Study on the Variable Star XX Andromeda

Study on the Variable leash XX AndromedaAbstractWe evidence the results of a month long V-Band study on the RRab face variable protagonist XX Andromeda. 4526 entropy points ar use to plot a light reduce, with 3 maxima sight and added to information from the GEOS database to create an O-C diagram. tercet regularitys of estimating the momentum degree are use, including two Phase Dispersion Minimisation methods and an O-C method, resulting in a better estimate of the intent of days. This value is in excellent agreement with the literature value for the purpose of XX And, from two the Hipparcos assort and the GCVS. The distance to XX And is estimated to be pc victimization a main grade fitting method to estimate the autocratic allege, and the mean radius is estimated to be . A flatfielding improvement to the photom.py railway report is suggested to combat pass around artefacts on the CCD. Physical reasons are discussed for the distinctive features present in the light curve, videlicet the Hump and the Bump.I. IntroductionIn 1893 Solon I Bailey super sense impressionted a program of globular stud studyi. He noticed that close to clusters (e.g Centuri) were extremely rich in variable stars with similar properties they had periods of less than a day, and light curve amplitudes of around 1 cartridge. The mean value of apparent order of magnitude of these stars in a particular cluster was in addition approximately the same across the sky. Bailey named these Cluster Type Variables. However an change magnitude progeny of stars with these properties were world found awayside of clusters indeed the brightest star of this type ever found was a field variable, RR Lyrae (after which the class is now named). Disc every siteies consequently began to come thick and fast, and it is certainly estimated that over 85000 exist in the Milky Way alonei. RR Lyrae variables gravel also been find in the Andromeda Galaxy, the Large Magellanic Cloud and new(prenominal) Local Group dwarf galaxiesii.Measuring the properties of these variables has become increasingly primal to astronomers, as it was realised that they could be used to gauge astronomical distances with a period- brightness level (P-L) relation, in a similar way to Cepheids. respective(a) catalogues have studied their properties, for example the General Catalogue of Variable Starsiii or the more recent Hipparchos Catalogueiv. Until recently however, no distinct P-L relation had been found, and instead astronomers had to use a relation between metallicity and visual magnitude or the Baade-Wesselink method, the drawbacks of which are discussed later. Currently there is still no P-L relation for V-band observations, although there are now relations for most of the infrared spectral bandsv.RR Lyrae variables are also of importance for the study of the population of both the Galactic Bulge (via Baades Window for example) and the Galactic Halo. Their advanced age an d suffering metallicity have with distinctive pulsation properties provides an excellent tracer for the development of the Milky Way in its early stages, as well as current kinematic analysisvi. They have also been used as a factor of quantifying the inter leading(p)(prenominal) reddening caused by dust in the galactic plane, thanks to the fact that the contort excess is a function of minimum (V-I) colour completelyvii. Using this reddening data with other distance indicators (for example red clump stars in the bulgeviii), a pregnant approximation of the distance to the centre of the bulge brush aside be obtained. Clearly thereof the study of RR Lyrae variables is recyclable for the infrastanding of the evolution of both the Milky Way and the rest of the Local Group.The star to be observed in this study is XX Andromeda (abbr. XX And), an F2 spectral class RRab type variable, located in the constellation of Andromeda at RA 1h 17m 27.4145s, decline +3857 02.026 (see 1). I ts pathrately high mooring in the sky at Durham means that it is circumpolar, whilst not exceeding the +65 limit for the setting fork mount, resulting in minimal atmospheric interference and the maximum possible observing quantify. The GCVS lists a period of. It is also known to exhibit the Blazhko effect, a long-period modulation of the amplitude of an RR Lyrae star (the cause of which is currently under investigation), with a period ofiii, and has an Fe/H value of -1.94.II. surmiseObservational TheoryCCD TheoryPerhaps the most important advance in astronomy in the hold water 20 years has been the widespread use of Charge-Coupled Devices (CCDs) to supersede photographic plates. Invented in 1969 at Bell Labs by Boyle and Smith, CCDs are a thin piece of semiconductor device physical (e.g. silicon) upon which lies an grid-like array of metal-oxide semiconductor (MOS) capacitorsx. During an exposure, if a photon impacts on the silicon an electron/hole pair erect be produced, as an electron is pushed up into a higher zip fastener state. The MOS capacitors act as occult potential wells ( pels), which hold the electrons until the exposure is finished. The charge is then read-out to an amplifier at one edge, in a specific order so that that the position of the original pixel can be identified, and related to the magnitude of the detected charge. The charge is converted from a raw bend of electrons into ADUs ( analog to digital units), the conversion factor of which is the grasp of the CCDxi.They are preferred to photographic plates in modern astronomical photometry for several reasons* High quantum efficiency (QE) for separately incident photon there is upwards of 90% certainty1 that an pair cede behind be produced. On the other hand, with photographic plates one can achieve (at stovepipe) an efficiency of 3%xii, so victimisation CCDs will increase the likelihood of detection of distant objects.* Large dynamic vomit up, allo compelg them to de tect objects with a range of magnitudes in the sky in the same exposure.* Strong linearity up to the saturation point, so that for longer exposure times the number of electrons produced is proportional to the integration time, whereas photographic plates will experience a drop in their efficiency. Their linearity will also mean that the magnitude of charge in individually pixel is linearly proportional to the brightness of the object.CCDs have also brought some inherent problems however, for example the sound associated with each motion-picture suggest. Because photons obey Gaussian statistics for bounteous counts, there will be a shot noise (uncertainty in the count rate) for each pixel of whereis the number of photons detected. Error in an run into also stems from both the incline of the CCD, and the twilit current present. The bias of a CCD is a systematic voltage off constitute across the whole CCD to prevent digital underflow during analogue to digital (A-D) conversion . It includes the read-out noise, a result of the manipulation of the pixel charge values during the A-D process and any charge-loss which occurs during the transferxiii. A CCDs unrelenting current is an unwanted flow of electrons which have been released from the surface of the semiconductor by thermal excitation, and is stringently dependant on the surface temperature, rather than being a function of illumination. For this reason the CCD was cooled by both the Peltier method (electrically) and with an active assisting fanxiv, to around 35C below ambient temperature, as the thermal current is approximately halved for each 7C reduction in CCD temperaturexii.To remove noise from an image, a set of normalization images may be earnn alongside each raw exposure. These are called bias and fatal effects. The bias chuck is a zero-time exposure which will include both bias and read-out noise. A dark frame can be found by leaving the shutter on the camera unappealing and pickings an e xposure seconds long. It can be expressed as, xv(2)whereis the dark current, andis the thermal noises statistical variation. ideally one would be taken before each exposure, as temperature figurely varies slightly with time. A outmatch dark frame can be found by fetching the mean(a) of a rotund number of dark frames, and will include the equivalent of a master bias. This master dark can then be subtracted from each image to leave a final, processed image with as low a random error as possible.The Automated Photometry ProcessSince the look into involved a bouffant number of images, the photometry processes were automated using several Python al-Qurans and FORTRAN routines.The record all.py was used to iterate the photom.py script over a range of images within a directory and print a string detailing which saddle was currently being processed.photom.py was the main script run, and was used to call several other processes which ran the photometry calculations, among other thi ngs. Firstly, it read in the point specified, and split the filename into the file and the extension, by using the find function to search for the wide-eyed tick as the delimiter.i=file_name.find(.)Using the extension to determine the file type, the script then either subtracted the master_dark.sdf frame (if it was a FITS file, and indeed a flying lizard turnout file) or converted it to a FITS file (if it was an ST9 file, and hence 14-inch, which had already had the dark frame removed). The conversion is achieved using two separate routines sbig2ndf, a routine from the SBIG python mental faculty which converts compressed output ST9 files created in CCDOPS into NDF files, and ndf2fits, which is a routine from the convert set of variables that converts the NDF files to FITS images. The subtraction of the dark frame is made using the kappa package from Starlink.photom.py then reads the variable star position from a user-created var_sky_position file. Using this, the script runs find_astrom.py. This attempts to match the stars in the image to the USNOA2 catalogue, and produce a new FITS file with the derived header solution. Firstly it takes the minded(p) star position as the centre of the image, and runs sextractor to find all the objects in the image. Next, it runs the WCS Tools routine scat at that RA and Dec to attempt to find any known objects in the region from the catalogue and prints it to a new file, usnoa_ref.catcommands.getoutput(scat+ -d -c ua2 -n 200 -m 17 r 600 +ra+ +dec+ j2000 usnoa_ref.cat)The pixel scale is taken from the directorys automag_driver file, and used by Andrew Pickles starfit script to match each object found by sextractor to the catalogues objects. This is achieved by the matching of triangles created between sets of objects in the sky to similar triangles created from the catalogues objects. Starlinks astrom routine is then used to change by reversal the solutionout=commands.getoutput(/star/bin/astrom fits=asc)print astro m returns, outFinally, find_astrom.py edits the header keys using pyfits to reflect the newly derived solution, and creates a new FITS image with the file ending _ast.fits.photom.py then runs sextractor again, to product a new catalogue of the objects from the image, complete with their RA and Dec. The script then performs the aperture photometry using automag.py. This measures the relative aperture magnitudes for the objects defined in the new object catalogue, by taking the number of counts within the specified aperture radius from the driver, and applying the blueprint(3)Here is a constant offset defined in the driver, is the number of counts within the aperture (which is pixels in size) minus the background, and is the integration time. Background errors are calculated by mensuration the counts within the two sky aperture radii to find the mean and rms sky-counts over pixels,and, and firstly deriving the signal to noise ratio for the star, by applying Equation (4) belowxvi.(4) In the above equation, is the gain of the CCD. By using the flux ground definition of the magnitude difference and manipulating the logarithm equation, the signal to noise value can be used to find the error on a measured magnitude, as shown in Equation (5).(5)These instrumental magnitudes are appended to the catalogue file, next to each object. auto_mag2list.py is subsequently run to pull the calibration stars from the catalogue, by matching the RA and Dec to those in the cal_sky_positions. The variable stars data, as well as the calibration stars data and the observation time in Modified Julian Days (MJD) are then appended to a file called summary.obs.in one case photom.py completes, the raw2dif routine can then be run to perform the differential magnitude calculation. This routine takes each line from the summary.obs file and subtracts the average of the two comparison stars instrumental magnitudes from the variable stars instrumental magnitude, . A zero-point constant is then a dded to put the differential magnitude on the standard scale. This can be measured by taking images of photometric standard stars (from the Tycho catalogue for example), and comparing their instrumental magnitudes to their known apparent magnitudes, as described in the next section.(6)raw2dif outputs simply the observation time, variable stars standardised magnitude, and the error on the magnitude to a user-defined file. magnitude Zero-point MeasurementThe zero-point is found by measuring the magnitudes of photometric stars with the telescopes, and comparing these to the values found for the stars in the Tycho catalogue. This catalogue uses a separate magnitude system, which can be converted into standard V-band magnitudes using the future(a) formula(7)The difference in these catalogue magnitudes and the observed values can then be used to show the difference that the specific equipment has made. This is the zero-point magnitude.Period DeterminationTwo programs are used for the per iod determination, the routine bforce and PDM win 3.0xvii.bforce uses a brute force method to find the period of the variability. It attempts to fit the data onto a user generated model of the light curve (with a phase endurance of 0.1), and wrap (or fold) it around a suggested period. The routine then splits the data into a serial publication of bins and estimates the variance in each, as follows, (8)for observations in each bin. If the trial period is incorrect, there will be a large scatter of magnitudes in each bin, i.e. a large variance. This is compared to the variance of the data set as a whole using an F-test, which is achieved by finding the ratioof bin variance (the explained variance) to total variance (the unexplained variance). For an incorrect estimate of the period 1, whereas for the correct periodThe PDM program works in a similar, if more refined way, implementing some of the recent changes in the accepted way of calculating a phase dispersion minimisation period. While still using a variation-based method, it finds the period using a beta-distri thation method (designated PDM*) rather than an F-test, as this has been shown to be the correct hazard distribution to usexviii. It also utilises a GUI with a series of user-set options, for example variable phase resolution.RR Lyrae TheorySubclasses of RR Lyrae VariablesFrom his observations, Bailey noticed three separate subclasses of variable, which have subsequently been compacted into two subclasses (as subclasses a b were truly similar). The following is paraphrased from Baileys original descriptionxix* Subclass ab Very rapid increase of magnitude, with a moderately rapid decrease in mag. Nearly constant mag for approx one half of the full period. Amplitude of roughly one mag and a period of between 12 and 20 hours.* Subclass c Magnitude always changing, with moderate rapidity. regulate generally half a magnitude, with a period of 8 to 10 hours.As our study concerns an RRab type variable, this class shall be primarily discussed. common characteristics of RRab starsRR Lyrae stars are large red stars with a low mass, occupying the airfield of the instability strip on the H-R Diagram (see Fig. 1) between -Scuti and Cepheid variables, where it intersects the horizontal branch. They are in the plaza atomic number 2 burning stage of their evolution, having exhausted their core hydrogen fuel. Mean physical properties of these variables are under some contention, but a summary of current approximations is provided in Table 1.Period0.2 1.1 daysMv0.78 0.02Te6404 12 KFe/H-1.56 0.25Mass0.55 0.01 MRadius5 1 RTable 1. Typical properties of RRab variables. All values are mean values of 335 variable starsxxi, except period which is a typical rangei.Evolutionary theoryIt is thought that the progenitor of an RR Lyrae star was a typical low-mass main grade star, with M* 0.8M. For the first 15 Gyr of its life, the star burns core hydrogen, fusing it into atomic number 2. On ce the hydrogen supply in the core is exhausted, the star expands to become a red ogre, moving off the main sequence and up the giant branch of the Hertzprung-Russell diagram (see Fig. 1), and shell-burning of hydrogen now occurs around an inert atomic number 2 core. The atomic number 2 core lastly collapses, becoming electron degenerate, and increases in temperature until the helium in the core ignites using the triple - process, causing the helium flash. The cores degeneracy is lost and the star moves off the giant branch asymptotically, down towards the instability strip. At this point it can develop the pulsational properties of an RR Lyrae star, although this will be dependent on its mass, its chemical composition, and its temperaturei.Once the helium core is also used up after around 0.1 Gyr, the star begins to expand and cool again, fuelled only by shell burning of hydrogen and helium. The core never becomes hot tolerable for the fusion of heavier elements. finally all t he usable fuel is expended and the star will jettison off its outer layers of material to leave a white dwarf star, shining only through the radiation of internal thermal energy. beatnik theoryThe study of pulsation theory owes much to Arthur Eddington, who wrote a series of papers detailing a mathematical description of the properties of stars. Having realised that a radial pulsation in a static star would have a decay time of around 8000 years (much shorter than the length of time stars spend in the instability strip), he proposed that stars behaved as thermodynamic heat engines, using some valve mechanism to regulate energy flowxxii. In order to fulfil pulsation, this valve would need to make the star more thermally opaque as the star was compressed, and less opaque as it expanded. Effectively this would cause energy to build up when the star was compressed, forcing the star to swell in size until some turning point was reached and the opacity was small enough that energy could e scape, leading to the star contracting again. The Rosseland mean opacity shows the overall opacity of a stellar region, and is defined as follows,(9)where is a constant, is the density of the region, and is temperature.Eddington was unable to come up with a particular material that would possess these properties in a star, particularly as during his time it was not believed that hydrogen or helium made up significant proportions of the inside of stars. It is also the case that neutral hydrogen or helium regions cannot be the valve region, as for these regions and i.e. as increases will decrease. This would lead to the pulsation dying out extremely pronto as all the radiative pressure was lost during contraction.However in 1953 Sergei Zhevakin found that regions of doubly ionised helium would provide an area wherebecomes small or negative, resulting in the desired properties for the gas. It was later shown by R. F. Christyxxiii that hydrogen ionisation can play a smaller, but still important, role in the mechanism.Ionisation zones can make another possible contribution to the valve in a star. If the energy from fusion processes cause ionisation in gas regions instead of raising their temperature, then the gas will absorb heat during compression stages, causing a pressure maximum near the minimum volume and thus aiding pulsation. This is known as the mechanism.unlike classes of RR Lyrae variable pulsate with different modes. For instance RRab stars all vary in the fundamental mode, whilst RRc stars are pulsating in the first overtone. This is one of the reasons that types a and b can be separated from type c as a separate class. A third class of variables has also been observed, termed RRd type stars, which have a double-mode pulsation, pulsating in the fundamental and first overtone modes simultaneously.However, some RRab stars show a long-timescale second periodicity, known as the Blazhko effect. This is an overarching period that can be anywhere between 30 days and several years. The cause of this effect is unclear, but is believed to come from either a nonlinear resonance effect between the radial fundamental mode and some non-radial mode, or a cyclical rotating magnetic field that deforms the main radial mode of pulsationxxiv. assessment of Absolute Magnitude and DistanceRR Lyrae stars are useful for the determination of astronomical distances, especially to regions such as clusters in the Halo, and the Bulge. However, unlike for Cepheids, accurate parallax measurements of distance do not exist for RR Lyrae variables (with the exception of a very few the star RR Lyrae itself for examplexxv), as the majority of stars are simply too far away for resolution currently2. Instead, astronomers look to alternative measurement tools, for example main sequence fitting or the Baade-Wesselink method.Main sequence fitting is the process of determining the distance to a cluster by fitting its colour-magnitude diagram to that of nearby main seque nce stars which have a parallax- laid distance. This has produced a wide variety of relations over the last twenty years, but a general relation (that is within error of the majority of current estimates) is devoted by H. Smithi(10)The currently favoured method of finding the metallicity is to use the relation, described by Jurcsik Kovcs in their seminal paper Determination of Fe/H from the light curves of RR Lyrae starsxxvi. This used a sixth order Fourier decomposition of the light curve to find multiple properties of an RR Lyrae star. When they plotted the data they found the following linear relation(11)This allows the metallicity to be determined accurately, and then used in the main sequence fitting method to find an accurate absolute magnitude for a star.Finding the absolute magnitudeis important, because it allows for the use of the magnitude equation to determine distance to an object, taking into account the galactic extinction in the direction of the object due to dust and gas in the galactic plane, (12)The Baade-Wesselink method, originally applied to Cepheid variables, was based on the assumption that a star will have the same surface temperature and brightness at all points of equal colour on the ascending and move sides of the light curve. This implies that any luminosity variation between two half-phases can be said to be the result of radial differences in the star. Thus a fractional radius change can be measured as. If a radial velocity curve is also plotted for the star, the radius change over the period can be directly measured, and through the combination of these two results a value for the luminosity of the star can be found. This can be used to show the distance to an RR Lyrae star through the relation(13)whereis Stefans Constant, andis the stars effective temperature.However RR Lyrae variables do not behave exactly like Cepheids for example during stellar expansion the surface gravity is much greater than when the star is contracti ng, leading to flux redistribution across the surface. This, combined with shock waves permeating through the stellar atmosphere causing distorted radial velocity curves, means that V band photometry is unfortunately useless for applying the Baade-Wesselink method to RR Lyrae stars. The procedure must instead be carried out in (V-H) or (V-K) colours for example, as infra-red wavelengths are less sensitive to the expansion phase distortionsxxvii. mind of RadiusMarconi et alxxv have published an equation relating the period of a fundamental mode RR Lyrae star to its average radius(14)whereis the mean radius (in units of solar radii), is the period (in days), and is the heavier-than-iron metallicity of the star, defined asxxi, (15)whereis the alpha-enhancement with respect to iron, and is taken to be equal to 1. This is derived from their theoretical predictions of the radial oscillations of a metal poor RR Lyrae, and applies to stars with helium abundances of between (0.24 and 0.28).I II. Experimental MethodsPreparing the experimentInital sittings were spent becoming aquainted with the computers Linux-based operating systems, understanding the basics of photometry and exploring the provided software. Several rooftop sessions were attended to gain knowledge of the telescopes provided, and to check up on safety procedures associated with the use of the equipment. Due to initial poor weather, previous years data was analysed in order to improve understanding of the provided scripts. A list of RRab targets from the NSVS cataloguexxviii was examined to find a sui display board object, with a magnitude range visible on the telsecopes available, a period of less than a day, and a high position in the sky.Table 2. Properties of the Telescope and CCD combinations for each dome. Both telescopes were fitted with the same model of V-band filter.Background information on the elect star (XX And) was found using the SIMBAD databasexxix, and examined to find previous studies, i ncluding estimates of period, metallicity, and star type, as well as dates of antecedently observed maxima. A plot of the field around the star was taken, and used to identify two calibration stars for the photometry ( 3)The calibration stars used were USNOA2.0 numbers 1275-00765817 (cal-star 1) and 1275-00761527 (cal-star 2). They were searched for in various catalogues to verify that they were not known to be variable. The best exposure time for our field was estimated to be 30 seconds with the 14-inch telescope, and 60 seconds with DRACO, so as not to change the image.By taking some sample images and viewing them in GAIA, suitable sizes for the apertures were chosen for each telescope. The sizes of the apertures were chosen to enclose the whole star, whilst giving the minimum error. These were then converted from scaled values to numbers of pixels, and entered into seperate automag_driver files for each telescope, along with the specific pixel scale, gain and read-out noise.Tel escopeStarSky InnerSky outermost14-inch4.714.921.4DRACO725.735.1Table 3. The aperture radii (in pixels) used for each telescope.Firstly, the convert variables were set up. XX Ands RA and Dec in decimal degrees were inserted into a file called var_sky_position, and photom.py was run on the first frame (called for example filename.fits). This produced an output file called amag.out which contained the positions of all the recognised stars in the image, as well as a calibrated image dfilename_ast.fits. By comparing the (x,y) pixel locations in GAIA for the two calibration stars with the data in amag.out the RA and Dec of the calibration stars were noted, and inserted into a text file named cal_sky_positions.Observation of the VariableObservations of the field containing XX And were then taken over a period of 1 month, using both the 14-inch Far East and the 10-inch DRACO telescopes. For the 14-inch, the observing process was as follows The object was located using the Earth Centre Uni verse program, the telescope synched and set to track, and the CCD programmed to take around 30 images per sequence at 30 seconds each, with an 8 second dark frame before each new image. For DRACO, the object was found using the provided G.U.I., with care taken to place the variable star and both comparison stars away from dust grains on the CCD. The telescope was set to track, and programmed to take a large number of images with a 60 second exposure. For each new observing session a seperate file was created, containing all the images and the scripts required for automated photometry. For DRACO processing, a master dark file was also copied from the archive. The file all.py was then amended to iterate over all the images in the directory, and set ravel.Once the photometry had completed, the raw2dif routine was run, and the results viewed by running qplot. The data were adjusted to Heliocentric Julian Days by running the cor2hjd routine, and the final tables were copied across to a main results directory to be added to the full table of data. bfplot was run on the full dataset using an estimate for the period, and the phase values from the output file fort.30 were killed out and yanked into the dataset file using EMACS. This table was viewed in TOPCAT, and a light curve created. any(prenominal) clear and accountable anomalies were removed in TOPCAT.To gain a value for the absolute magnitude of XX And, rather than simply an instrumental magnitude, a series of observations were made of photometric stars which had known magnitudes. These are shown in table 4 belowPhotometric StarRADecApparent V-band Magnitude11h 18m 20.581s38 55 38.239.84721h 14m 50.729s38 29 55.809.96131h 15m 12.229s38 49 10.959.04841h 16m 39.436s39 09 38.649.735Table 4 Properties of photometric stars used in the magnitude calibration of XX And.This gave a value for the correction which had to be made to all the observed values for each telescope. The corrections were then applied to the full dataset.An O-C diagram was constructed using the data from the Hipparcos mission, the GEOS RR Lyrae Survey, and also archive data from the GEOS databasexxxi. The period used was the Hipparcos estimate. Since the newly observed data used HJD, and the archive data was in modified HJD, an addition of 0.5 HJD has to be made to the new data in order to be comparable. The newly observed data was then added to the diagram, and the input period was altered to give the flattest line possible, thus providing a new estimate of the period. The error on the period is given by the slope of the linexxxii. Any historical period changes were searched for in the line of the O-C plot.The fast_solve routine was run on all of the summary.obs files, and the comparison stars were check to see whether or not they were varying. The output model file from fast_solve was edited to include estimates of bin values where there was no actual observational data, and then used in the routine bforce. This was run u sing the period quoted in the Hipparcos catalogue as the initial period to give an estimate of the new period and its error. The period was also estimated using PDMwin, using an output table from TOPCAT.Errors in the period-finding were estimated using the Jackknife method on both the PDM and bforce programs. This was achieved by recomputing the period, but leaving out one observa

A Literature Review On Adventure Tourism Tourism Essay

A Literature Review On hap Tourism Tourism EssayAdventure whirlis return has become more popular as an outdoor recreation manageivity in the tourism industry (Travel Industry Association of America, cited 2005). The term take a chance piece of ass actually stiff some(prenominal)(predicate)ly to different tourers because things that fill up the fear of matchless tourist whitethorn non fill up for anformer(a)(prenominal) tourist (Buckly, 2006). Therefore, there is no any specific way to define calamity tourism. The word happen is described as the risky activities in nature that ar taken on by the tourist or the risky close visited by the tourist and the tourist get an exciting and unusual run into from what the tourist had did (Farlex, The Free Dictionary). Adventure also is where the participants voluntarily putting themselves in a position that the participants abstractize that they atomic number 18 taking a step into the un go to sleepn where challenges impart be faced and something valuable from the pick up will be discovered or gained (Swarbrooke, Beard, Leckie, and Promfret, 2003). Consequently, adventure tourism is something link up to nature and it is consisting of risk taking. muser and C topr (2000) (cited in Swarbrooke et al. 2003, p. 29) defined adventure tourism as the cap qualification to provide tourists with relatively senior high degrees of sensory stimulation. It is usually contained some fleshly challenging elements with the (typically short) tourists experience. While Buckley (2006) mentioned that the term adventure tourism is utilise to mean as guided commercial tours where these major magnet is an outdoor activity that has natural surroundings features and normally of necessity specialized sporting or equipment. It must be exiting for the tourists also. This definition does non mean that the tourists or clients hasten to prepargon the equipments themselves, they may purely be hold outlers and rely on the agen ts to prep be the equipments for them. For example, bicycle-built-for-two parachute harness or white water raft, etc. Therefore, adventure tourism gage name to activities done by the tourists, which have high level of perceive or real risk same diving, hiking, mountaineering, mountain biking, caving, sky-diving, skiing, snowboarding, white water rafting, kayaking, sailing, and sea kayaking. It also refer to a specific location of focalise with high degree of risk such as visiting desserts, jungles or mountaintops, polar regions and safaris. All these places have strong elements of adventure.Adventure tourism can be divided into soft adventure and enceinte adventure. These call atomic number 18 authentic by researchers who devised a scale to explain the diversity of deportment, beginning with mild adventure also known as soft adventure at one end of the scale and surface to hard adventure at the other extreme. This continuum, illustrate in descriptor 1.1, involves differ ent degrees of challenge, uncertainty, setting familiarity, in-person abilities, intensity, duration and sciences of control (Lipscombe, 1995 42). A simpler way to describe soft and hard adventure is that soft adventure does not necessarily require past experience whereas hard adventure requires some experiences and proficiency in the activity prior to the tourism experience (Millington and Locke, 2001).Hard AdventureRefers to activities with high levels of risk, requiring intense shipment and advanced skills.Soft AdventureRefers to activities with a perceived risk provided low levels of real risk, requiring minimal commitment and beginning skills most of these activities are led by experienced guides.Figure 1 The continuum of soft and hard adventure (source Hill, 1995, cited in Beard et al. 2003, p. 33).Tourist behaviour is an in-depth topic as the behaviour of tourist interchange from time to time and sometimes it can be difficult to judge because not everyone shares the sam e behaviour. In redact to understand tourist behaviour, psychologists have found that certain concepts are useful to understand the behaviour (Bhatia, 2006). According to Bhatia (2006), tourist behaviour can be understand by determining the motive, drives, or concerns world comfortable by the action and the attitudes and entropy that the person use to decide what kind of response should be made in a given situation. motivating is one ways to describe tourist behaviour. Motivation is a verb derive from motivate Motivation is f proletarian that influence or motivate trekkers to give way to Everest bagful Camp. Motivation is defined as a reason or reasons for acting or behaving in a particular way or the disposition or willingness to do something (Oxford online Dictionary). Hence, indigence of conk is wherefore tourists expire to a place. It is important to know tourist travel penurys because motivations will affect travel close do (Crompton and McKay, cited in pan 2009 , p. 216) and motivations are drivers that influence and affect the specific behaviour of a person or traveller. Furthermore, it also helpers to develop strategies to attract tourists to a particular destination by understanding tourist behaviour. For example, travel agent or local authorities can find a way to increase the book of tourists visiting a destination by understanding the tourist behaviour when the destination is kind of innovative in the tourism market or the number of tourists in the destination had decreased. Travel motivation is a wide possible action where it can not be understood by looking at one part of the theory all.Figure 2 The Motivation Process (source Holloway, Humphreys Davidson 2009, p.62).The process of translating a need into motivation to visit a specific destination or undertake a specific activity is kinda complex and can be best demonstrated by means of a diagram (refer to Figure 2) (Holloway, Humphreys Davidson 2009, p.62). Potential consume rs must be able to recognize their needs and wants and know what kinds of crossway actually encounter their needs. Figure 2 shows that consumer cognition of what will satisfy their need has to match with consumer perception of the attractions. Only when the consumer agrees on these 2 points, consumer will be motivated to visit a particular destination. For example, client A and customer B have the same kind of need, where both of them like to do adventure activities and their hypothecate that trekking up to a mountain satisfies their need. Both customer A and B have the same stakes but their perception on a particular destination may be different. Customer A may think that trekking to Mount Everest actually fulfils what he wants and his perception towards the destination is positive. While customer B may think that trekking to Mount Everest fulfil what he wants but he has a bad perception towards the destination as he think that the destination is very risky to him. Therefore, customer A will be willing to buy the package and climb up to Mount Everest because both the perception of the need and the attraction match. Customer B will not be motivated to go to Mount Everest as the perception of need and attraction do not match.According to Beerli and Martin (cited in Correia, Valle and Moco 2007, p. 46), motivation is the needs that drives and individual to act in a certain way to achieve the go for satisfaction. Therefore, community travel base on many different reasons. Motivation has also been referred as psychological / biological needs and wants including integral forces that arouse, direct, and desegregate a persons behaviour and activity (Dann Pearce Uysal Hagan, cited in Shin 2009, p. 32). Travel motivators are the factors that create a persons desire to travel and are usually the internal psychological influences affecting individual choices (Bhatia, 2006). Travel motivations usually overwhelm a wide range of personal experiences and behaviours. Various studies have been done to find out why people wish to travel after the advent of mass tourism, especially after the Second institution War. Macintosh (cited in Bhatia 2006) has group the basic travel motivators into tetrad categories.Physical motivators, which are related to physical retardation, refreshment of body and mind, sports, pleasure, and special medical treatment. All these are attached with individuals bodily well beings and connected to activities which help to reduce tension.Cultural motivators, which are related to individuals desire to travel in order to know more about other countries, natives of the countries and cultural heritage of the countries which expressed in art, music, dance, folklore, etc.Interpersonal motivators, which are related to individuals desire to meet new people, visit friends and relatives, and to look new and different experiences. Travel is scarcely to escape from the daily routine or get away from the usual life or environment. position and prestige motivators, which are related to the needs of personal esteem and personal development in an individual. such motivators are more likely to be concerned with the desire for recognition and attention from others, in order to boost personal ego. Under this kind of motivations, people usually travel for business, for the purpose of education and the pastime of hobbies.Crandall (cited in Hall pageboy 1999) who did a dissect on the motivations of the leisure time travellers, outlined 17 motivational factors which derived from a synthesis of previous studies in this field. Below are the 17 motivational factors listed by Crandall.1ENJOYING NATURE, ESAPING FROM CIVILISATIONTo get away from civilisation for a bit To be close to nature10RECOGNITION, STATUSTo show other I could do itSo other would think highly of me for doing it2ESCAPE FROM ROUTINE AND RESPONSBILITYChange from my daily routineTo get away from the responsibilities of my daily life11SOCIAL POWERTo h ave control over othersTo be in a position of ascendence3PHYSICAL EXRCISEFor the exerciseTo keep in shape12ALTURISMTo help others4creative thinkingTo be creative13STIMULUS SEEKINGFor the excitementBecause of the risks involved5RELAXATIONTo relax physicallySo the mind can slow down for a while14SELF-ACTUALISATION (FEEDBACK, SELF-IMPROVEMENT, efficiency UTILISATION)Seeing the final results of your effortsUsing a variety of skills and talent6SOCIAL CONTACTSo I could do things with my companions To get away from other people15ACHIEVEMENT, CHALLENGE, COMPETITIONTo develop my skill and abilityBecause of the competitionTo learn what I am capable of7MEETING NEW PEOPLETo lecture to new and varied peopleTo build friendships with new people16KILLING TIME, AVOID tediumTo keep busyTo avoid boredom8HETEROSEXUAL CONTACTTo be with people of the mated sexTo meet people of the opposite sex17INTELLECTUAL AESTHETICISMTo use my mindTo think bout my personal values9FAMILY CONTACTTo be away from the family for a whileTo help bring the family together moreTable 1 Crandalls list of motivations. Source Crandall 1980 (cited in Hall Page 1999).Pearce (cited in Pan 2009, p. 218) who had ground and expanded on the theory of Maslows hierarchy of human needs, offset developed the travel career ladder approach to travel motivation in 1988 and later made conceptual adjustment to the travel career ladder in 2005. The fundamental nature of this model connects the level of travel experiences with the hierarchy of travel needs. According to Pearce (cited in Pan 2009, p. 218), travellers who had more experiences in travel usually seek experiences that meet their higher order of travel needs such as self-esteem and self-actualization. On the other hand, inexperienced travellers will tend to seek experiences that meet their basic travel needs such as security and psychological ones. Tourism industry is a dos industry and the products which offer in tourism industry are intangible. It is wid ely known that to travel is to experience. Consequently, tourist experience is fundamentally a service experience.The five level of travel career ladder, starting from the bottom are (1) concern with biological needs (including relaxation), (2) safety and security needs or level of stimulation, (3) relationship development and extension needs, (4) special interest and self-development needs, and (5) fulfilment of deep involvement needs which formally defined as self-actualization (Pearce cited in Marafa, Ho Chau 2007, p.8). This travel career ladder is later presented graphically by Ryan (cited in Marafa, Ho Chau 2007, p.8), refer to figure 3. It is not necessary that everyone has to start from the bottom because people change from time to time and some may try to seek for activities which satisfy high level of needs in pursuit of leisure and recreation (Marafa, Ho Chau, 2007).Figure 3 Travel Career Ladder by Ryan (cited in Marafa, Ho Chau 2007, p. 9).Another theory which often use by researchers when describing travel motivations is the excite and pull out theory. This theory shows that people travel because they are pushed and pulled to travel by some factors. Dann (cited in Pan 2009, p. 219) whom had combined and analyzed the relevant travel motivation literature, concluded that travel occurs due to the internal factors of indentified and unfulfilled desires (motivational push) and reinforce by orthogonal factors which is destination pull. publicise factors are either internally generated or externally induced (Dann, cited in Pan 2009, p. 218). The desire to spank a mountain by reaching the summit of the mountain is one of the examples of push factors. While pull factors are related to the attributes of the destination that serve to satisfy the needs and wants of travellers.Several authors assume that internal and external factors are factors that motivate human behaviour. For example, Kotler (cited in Correia, Valle and Moco 2007, p. 46) states th at motivations can be the result of internal and external stimuli. upcountry factors are factors derive from personal needs and wants such as psychological, fond egocentric, self-actualization and safety. While external factors are usually result from promotion and publicity. Travel motivation can be either personal (personal training, stipend rest and knowledge) or interpersonal (resulting from social relation) (Crompton, 1979 Dann, 1977 Yoon and Uysal, 2005, cited in Corriea et al. 2007, p.47).Iso-Ahola Ryan Glendon (cited in Pan 2009, p. 219) argued that travel motivation is well-nigh related to leisure motivation and the former should not be studied independent of the latter. Iso-Ahola (cited in Alexandris, Kouthouris, recoil Giobani 2009, p. 482) defined tourism motivation as a meaningful set of mind which adequately disposes an actor or a group of actor to travel. Approach (seeking) and avoidance (escaping) are the two components in leisure motivation, identified by Iso -Ahola. Therefore, people travel in order to seek friendship, novelty, challenge, achievement, experience, and etc. while at the same time escape from the daily routine or personal problems. While Ryan Glendon (cited in Pan 2009, p. 219) applied an abbreviated version (14 items) of the Leisure Motivation Scale of 1,127 United Kingdom holidaymakers and identified four motivation factors from the scale which were apt, social, competence mastery and stimulus avoidance. The first three factors could be categorized as seek components and the last factor as escape component.Crompton (cited in Kao, Patterson, Scott, and Chung 2008, p. 18) studied travel motivation by using push and pull model and developed seven socio-psychological or push motives (escape from a perceived mundane environment, self-exploratory, relaxation, prestige and regression, enhancement of kinship relations, facilitation of social interaction) and two cultural motives or pull motives (novelty and education). This st udy refers to motives which are more specific and direct that can affect tourists decision on the travel decision or the type of holidays (Crompton, cited in Corriea et al. 2007, p.47). The author identify that psychological or social motives (push motives) sustain the desire to travel. While on the other hand, travel decision if affected by pull motives and pull motives are also associated to the destinations characteristic (Lundberg, cited in Corriea et al. 2007, p.47).A study was done to explore the motivations and satisfactions of Taiwanese Tourists who visit Australia (Kao, Patterson, Scott, and Chung, 2008). upgrade and pull approach was used to find 17 push motivations and 18 pull motivations for travel in this study. The most important push factor found in this study is Travelling around the world, while the most important pull factor is sunshine and scenery and most of the Taiwanese tourists are satisfied after visiting Australia. Study done by Chang (2007) on travel motiv ation of package tour travellers suggested that socio-psychological needs were an important motivation for travel, and socio-economic considerations were regarded as a crucial motivation for travel decision making. Furthermore, social relationships friends or relatives recommendations had a strong impact in the decision makings of the Taiwanese travellers (Chang, 2007). This study was done to psychoanalyse travel motivations and travel decision-making of Taiwanese tourists with a group package tour abroad. Therefore, it can be give tongue to that tourists travel to a destination is strongly influenced by their socio-psychological needs.Tourist builds his/her perceptions based on intrinsic and foreign motivations (Gartner, 1993 Dann, 1996 Baloglu, 1997 cited in Corriea et al. 2007, p.47). Everyone receives and processes info differently. Therefore, individuals perception is also formed differently base on how the selective information is trustworthy and transformed. According to Oxford online dictionary, perception means the ability to see hear, or become aware of something through senses or the way in which something is regarded, understood, or interpreted. scholarships are also defined as the perceived value of product by many previous researchers (Correia and Crouch, 2004 Correia et al., 2007C Holbrook, 1996 oh, 2000 Sheth et al., 1991 Zeithaml, 1998 cited in Correia and Pimpao 2008). This concept develops based on cognitive and behavioural perspectives which result from the learning and motivational processes rendered by the tourist. Therefore, perception is the point of views about what the tourist think about the destination.Perception of a destination is linked to the destination come across. Based on the image of the destination, perception of the destination will be generated and each tourist will have their own perception about the destination. Destination image is described as overall perceptions of individuals regarding a place or total set of impressions about a destination (Bigne et al., 2001 Fakeye and Crompton, 1991 cited in Alvarez and Korzay 2008). Destination image is usually formed through media, either positive or negative images. This is based on how the country promotes the destination in its country and through world news, people can tardily know the problems or issues in the country. Hence, the destination image will be easily affected and it changes over time because people build up the destination images and representations based on the information that they receive (Avraham, 2000 Sonmez and Sirakaya, 2002 cited in Alvarez and Korzay 2008). In 21st century, internet is the most powerful media that affect customers perception and destination image. In the world of internet, people can easily source for information regarding the destination and leave comments on the blogs or travel discussion forums after visiting the destination. Therefore, people nowadays not only listen to their friends past travel ex periences but also read the worldwide tourists experiences from travel blogs or travel discussion forums. It is important to know what Malaysian trekkers think about Everest Base Camp which can be risky.Corriea et al. (2007) did a research on why people travel to exotic places by combining motivations and perceptions. This is the first time and they are the first few researchers that combine motivations and perceptions in order to understand how people can be pushed to travel to exotic places and how they form their perceptions. In this research, Corriea et al. (2007) try to find the relationship between push and pull motivation, push motivation and perception, and pull motivation and perception, based on a group of Lusitanian tourists who go to exotic places such as Brazil, Morocco, Egypt, Sao Tome, and Principe. This study proves that perception of tourist destinations are formed based on push and pull factors but the relationship between push factors and perceptions in not larg e and this proves that tourist decides to go for travel because he/she need to solve a conflict arousal (rest, social, and intellectual rewards) (Corriea et al. 2007). After that, the tourist will decide where to go based on the destination attributes. Destination attributes (pull motives) are seen as the way to solve intrinsic motives (push motives) in this study, but these constructs are not directly related to the overall perceptionof the destination because they are apparently solved when the tourist turns the attention to specific attributes (Corriea et al. 2007).Gnoth (1997) reports that the perception of a destination may be analysed from a cognitive or behavioural perspective. There are several(prenominal) types of perceptions which are cognitive component (which results from the evaluation of the destination attributes) and personal component (which results from the evaluation of the destination attributes) that a person can have, argued by Gnoth (1997).Travel motivation is an extensive researched area in tourism (Pan, 2009). Consequently, there are many theories that describe about tourist motivation to travel suggest by several authors or researchers as different tourist have different mindset and behaviour. Furthermore, there are many forms of tourism and tourists can be clustered into various types of groups. Perceptions of travellers on a particular destination can be unlikely because everyone thinks differently. Due to different in culture and the way they receive and transform the information will affect the perception of the tourists.Conceptual FrameworkFigure 4 Conceptual Framework schemeTrekking in Everest region is the dream of most of the Malaysians trekkers.Its part of self-fulfillment of the trekkers and they want to challenge themselves as Malaysia does not have mountains which are more than 5000m and Everest is the highest mountain in the world.Malaysians trekkers travel to Everest Base Camp but not to the summit of Mount Everest becau se budget and time limit them to trek to the summit of Mount Everest.Additional informationObjectiveTo know the factors that motivate them to take Everest base camp trekTo understand travelers perception on Everest base camp, Nepal as a tourism destination

Sumitomo Corporation And Yasuo Hamanakas Copper Scandal Finance Essay

Sumitomo Corporation And Yasuo Hamanakas Copper S pottydal Finance renderThe financial realness had been confronted heavily by craft scandals in 1995, with Japans Daiwa Bank and the rouge trader, Nick Leeson. When it seemed the scandals couldnt digest oft worse, the Sumitomo Copper Scandal emerged. This was the biggest scandal in the history of commodities traffic and ranked in the die fiver trading handoutes in financial history up until the late 1990s. Sumitomo Corporation is a Japanese trading house, which is currently one of the giantst worldwide trading companies headquartered in Tokyo, Japan. In the 1990s Sumitomo have crowing hearts of both physiologic cop, which was stored in w behouses and factories, as strong as numerous futures contracts. Copper was a relatively sm exclusively food grocery store place compared to other metallic elements, such as atomic number 13. According to Andrew Beattles article, The Copper King An imperium Built on Manipulation, tomentum is an illiquid commodity that cannot be comfortably transferred around the world to meet bypassages. For example, a rise in shit impairments due to a piddlingage in the United States will not be immediately cancelled out by shipments from countries with excess copper. This occurs because moving copper surrounded by computer memory and delivery costs money, which can cancel out the value differences. It is important to note that Yasuo Hamanaka was the chief copper trader of this trading house, and attempted to time out the full(a) worlds copper market leaving Sumitomo with a disadvantage of more than than $1.8 billion (Beattle).WHAT HAPPENEDFor ten-spot years, Yasuo Hamanaka had successfully managed to control the worlds cost of copper. He eventually came to control five pct of the entire supply of copper, which may not seem like much considering ninety-five pct was in other traders hands (Beattle). However, due to the fact the abundant and cumber approximately challenges that exist in the copper market (in movement, delivery, etc.) and the fact that even the largest traders in the market own an even smaller percentage, Hamanakas five percent was indeed very significant.During the ten years of his manipulation he was equal to(p) to use Sumitomos size and large cash reserves to corner and squeeze the market through the London alloy Exchange. The London Metal Exchange is the worlds biggest metal exchange. Furthermore, the London Metal Exchanges copper legal injury essentially dictated the worlds copper price at the time (Beattle). Although the London Metal Exchange was large in size, it was fairly poor in legal injury of regulation. In fact, this exchange had little to no regulation at the time of Hamanakas rampant market manipulation. The Sumitomo Copper Scandal lasted for some a decade due to these negligent and almost nonexistent regulations on behalf of this particular exchange.To put the entire crisis into laymens terms, one must first understand that Hamanaka was taking a yen futures position on copper and simultaneously corrupting up a substantial amount of physical copper as well. This caused any one trader who took a short futures position to have to buy long positions in order to cancel out their short positions. Due to the fact that Hamanaka had a large number of long positions, those slew looking to buy them had to pay increasingly higher prices. These skyrocketing futures prices are what Hamanaka was able to control the more the prices rose, the more money he made. This is because those with short positions were still paying this higher price in order to liquidate those positions. Another way that Hamanaka was making money was that while these prices continued to rise, some people holding short positions thought that instead of paying a high price for a long position they would buy the physical copper and deliver it to the holder of the long positions. So, because Hamanaka alike owned 5% of the p hysical copper he could charge a very high price to those with short positions because they didnt want to keep paying money to liquidate their short positions. Essentially, he was making money by owning long futures as well as physical copper.WHYThere are no secure reasons as to why Hamanaka engaged in such wicked trades. Perhaps he felt pressured to concord the consistent levels of annual revenue for Sumitomos traditional copper business-about ten billion dollars. He would therefore save his reputation as a phenomenal copper trader as well as his firms mastery in the commodities market.It is also important to note that individuals such as Hamanaka, do attempt to corner the market in order to create an unfair advantage by purchasing a significant amount of shares. This eventually increases the price of shares, making them appear to have a greater value. As the price of the shares continues to rise, more buyers become attracted, and then demand further increases the price of the shares. This causes short sellers to be driven out of the market through a short squeeze. In the article Short Squeeze, it explains that a short squeeze is a situation in which an increase in the price of the stock triggers a rush of buying military action among short sellers. Therefore, it is necessary for the short sellers to buy stock in order to close out their short positions to minimize their losses, causing a further increase in stock prices. Overtime, this causes one to sell their holdings at an artificially inflated price and then leave their investment or opt to sell their shares with the cognition that the price will decrease once normal supply and demand forces return (Investing Answers).WHO WAS RESPONSIBLEYasuo Hamanaka, also referred to as Mr. Copper, was the former copper trading chief for Sumitomo Corporation. Following research of the Sumitomo Copper Scandal, one can confidently say that Hamanaka is the key player who is held responsible for the 2.6 billion dollar loss over a ten-year period. In fact, the article, Sumitomo Corporation states that, it believed that Mr. Hamanaka was solely responsible for the unauthorized trading (215). His attempted action to corner the worlds entire copper market by falsifying financial records and forging signatures alluded to such a significant loss for the participation.It is also important to note that prior to the discovery of Hamanakas accumulation of illegal trades, he was given a great amount of responsibility at heart the company. This was because he was perceived by top executives to have super knowledge and experience within copper trading. Therefore, one can also conclude that the top executives within the corporation can also be held responsible for the Sumitomo Copper Scandal. This is because the Sumitomo Corporation and senior focusing did not have secure safeguards in place to ensure that they knew exactly what their employees were doing. Furthermore, Hamanakas reputation as being a super star copper trader only ploughed to solidify the lack of regulation and discipline (Sumitomo Corporation).When Sumitomo Corporations reputation began to daub from individuals outside the company, they responded to the allegations by stating that Merrill Lynch and JPMorgan Chase were the dickens banks responsible. In the article The Copper King An empire Built On Manipulation, author Andrew Beattle explains that Sumitomo Corporation claimed that Merrill Lynch and JPMorgan Chase granted the loans to Hamanaka via future derivatives hence the two banks kept the scheme going. Consequently, both banks were found guilty to some extent (Beattle).RIPPLE EFFECTS ON THE MARKETHistorically, there has been a close correlation in the behavior of metal prices. When one metal falls, the others tend to follow. However, the Sumitomo announcement did not harm other metals notwithstanding the recent dramatic drop in copper prices. Copper is a relatively small market compared to other metals, such a s aluminum and gold. The price of the metal was above $1.25 a pound in New York in advance(prenominal) may of 1996, however it fell to $1.04 on June 13, just before Sumitomo announced its loss. Following the announcement, copper was trading at about 89 cents (Wall). The decline in prices of copper before the Sumitomo scandal was believed to have risen from people being relate about the number of new copper mines that were planned and the potential supply problems that it could buzz off about (Wall). Copper prices fell ten percent in the weeks following Hamanakas removal (Fletcher), however, prices had been falling for a while, and the scandal only exacerbated the trend (Uchitelle).The main effect of Sumitomos losses was the decline in public self-assertion in financial institutions. Americans wondered how well their local financial institutions were handling oversight of management. They also were concerned about a temporary decline in stock prices as well as higher pursuit r ates for money to seek to borrow from banks (Uchitelle).The dollar is driven by peoples perception of commodity price movements, and although the dollar had weakened before news of the Sumitomo scandal, the fall in copper prices has contributed to the dollars softness (Wall). The Sumitomo affair concerned the United States about the openness of Japans financial system and the implications for interest rates. These worries as well as the copper crisis had contributed to the decline of the yen. The collapse in copper prices also hurt the Australian dollar.RISK MANAGEMENT ERRORSIn the Sumitomo copper scandal, the financial debacle originates from the failures of proper risk management. By entering into fictitious trades for over ten years and manipulating several accounts, Hamanaka successfully misled his management into believing that he was making huge profits. Hamanaka had been trading on the London Metal Exchange forward market for copper. Sumitomo was the largest participant in th e physical market for copper-he handled doubly the volume as his competitors. Hamanaka was known in the copper markets as Mr. Five Percent because Sumitomos copper trading team traded approximately 500,000 metric tons of copper a year, which was five percent of the total world demand for copper (Weston).In regards to risk management, whenever any hedge fund or speculator who was aware(predicate) of manipulation tried to take short positions, Hamanaka invested more money into his positions, thus sustaining a higher price because he dominated the market. However, despite these illegal practices no action was taken against Hamanaka because of the profits he generated for the company (Weston).There are several reasons from a management perspective as to why the scandal carried on as long as it did. The middle office may have bypassed early warning signals perchance because Hamanaka was perceived as an experienced senior trader. Hamanaka was chief of the trading office and intentional ly had an incentive to maximize profit opportunities through illegal ways. Employees within the firm may have allowed the fraud to occur by turning the other way. This is a case of decentralization (Tschoegl).The Sumitomo scandal has provided valuable insight and enables one to regard and understand the importance of internal and external controls. If there had been any controls, it is believed that the scandal would have been detected much earlier and before a loss of $1.8 billion.WAS IT PREVENTABLE? IF SO, HOW?The Sumitomo Copper Crisis was, at its core, a very preventable crisis-almost embarrassingly so. The huge financial swings that the copper market saw in the late 1980s and early 1990s as a result of Hamanakas indiscretions were exactly that the result of one mans greed and indiscretions. Hamanaka initiated and participated in the illegal trade of copper-like making off the book deals in order to recover unrealized losses-and incited a curl of regulatory laws by the London Metal Exchange and the Commodity Futures Trading Commission (CFTC).Hamanaka exploited respective(a) agents and partnerships in his ten-year long market-manipulating extravaganza. He was able to do this due to serious misgivings and loopholes in the commodity futures markets, as well as taking advantage of gaps in the chain of command and knowledge. Hamanaka maintained two unlike sets of trading books one that recorded fabricated profits for the Sumitomo Corporation and another real record of all the off-the-book and under-the-table deals that were made to maintain control of the market. This long-term interference and domination of the copper market was until now very hard to maintain due to one key fact in order to corner a commodities market, the company must actually hold the assets, which presents an additional strain on resources and funds. This very need may be the answer to preventing scandals like this in the future (Wall).As aforementioned, the Sumitomo Copper Crisis was largely undeniable simply because one mans poor decisions affected the rest of the affiliated market. The essence of the problem was unauthorized trading that the culprit undertook to enhance his firms profitability and then his own career and pay, Adrian Tschoegl mentioned in The Key to Risk Management. However, the full-strength debacle is a result of a lack of internal and external controls. The Sumitomo Corporation, which was divided into essentially troika separate offices (front, back and middle), simply did not harbor or even encourage communication between departments and sectors (Tschoegl). The middle office (which is responsible for one of the most key business functions risk management) can easily be said to have failed most spectacularly in this scandal. The lack of risk awareness and management led to a loss of $1,800 million dollars and a stain on the Sumitomo name, all because of a decentralized, non-communicative collective structure (Tschoegl).The most effectiv e approach to reverseing something like this in the future is basically three-pronged more and get out management-level controls, independent transaction monitoring, and more stringent regulation (of the London Metal Exchange, by the government, and of corporations e.g. corporate kindly responsibility) (Tschoegl). The management-level controls should consist of a conscious effort at centralizing every part of the company, as well as maintaining strict inter-company discipline and training. Independent transaction making should be monitored so no two-book history systems are permissible that is to say, that there is a system of checks and balances within the corporation to ensure above-board transactions. In terms of regulation on behalf of various agencies and governments, its only necessary to say that more of it is probably needed to avoid price manipulation. Perhaps a system of rigorous reporting and accounting policies could be implemented, which would strengthen the markets long suit anyways.CONCLUSIONIts fair to say that the Sumitomo Copper Crisis leaves the skilled and careful trader with a few frigid takeaways. First, both internal and external management controls are absolutely crucial to the success of any company, but if said management is left to run unchecked through the system, mishaps and misdeeds are bound to occur. Strict and exchangeable corporate training and discipline is the remedy to this pitfall. Second, given the right amount of determination and finesse, the market on almost any given commodity can be cornered, for better or for worse. Events like this, despite their far-reaching negative implications for the perpetrator, always help make the market a more efficient and fluid network. The lessons that are learned from scandals such as the Sumitomo Copper Affair in the long run only work to better and enhance the market.

The e-commerce has been adopted into the core of the business in three ways 1) in its relationships with end customers, (2) in coordina ting its value clear, and (3) in communicating its market message to emphasize its ability to provide e-commerce solutions to its customers. As per Anderson and Narus, approximately of the emerging applications of CRM, (that we can likewise observe in Dell) are inCustomer acquisition, retention and growthSynchronizing marketing effortsUpdating delivered valueCustomer Acquisition, Retention and GrowthDell has involved the Internet in all aspects of customer relationships, ranging from customer acquisition, retention and growth to marketing. The internet is used in supporting existing channels such as the direct sales force and call centers by providing them with real time breeding and automating their routine tasks. It has also developed self-service tools for customers, using which they can order online, track order status or solve a skillful problem through and through the Internet or an extranet.AcquisitionDell sells its own products at the dell.com website. On the homepage, customers in the U.S. are segmented into home and home office, medium and large organizations, Internet providers, health care businesses, federal government, state and local government, and education. Each customer segment has a different mix of products and go on hand(predicate). Customers can choose and price different configurations with Dells online configurator. Once they are ready to buy, their order is sent to a shopping cart. They can also choose mixed addons such as software, peripherals, digital cameras, PDAs, etc. on the Gigabuys or DellWare sites and add those to the said(prenominal) shopping cart. Once an order is entered, the customer receives an order number that can be used to track order status until it is delivered.Premier Pages are customized for every customer and they include capabilities for procural, asset forethought, software upgrading, and even practiced support. Large relationship customers can cause Premier Pages customized even further to link t o their own internal procurement systems, allowing their orders to be sent directly from the customers office breeding systems to Dells order management system.Dells account teams work with such customers to set up Premier Pages, aspect access levels and registering substance abuser names and passwords for employees, and customizing the randomness and the kind of services that will be in stock(predicate). Dell also provides a few tools for customers to establish their own pages. The various services available through Premier Pages include_ procure narration reports The complete history of a customers leverages from Dell, including PO number, order number, date, SKUs, quantity, shipment dates._ Standard configurations To make a customers PC administration processes simplisticr (installation, upgrades, help desk, technical support), the customer can specify a definite set of configurations for different employees. These are make available for ordering on the customers Premier Pages at the price negotiated between Dell and the customer._ Paperless online purchase orders Dell and the customers sign a legal agreement that allows the customer to place orders without mailing or faxing a signed purchase order. This lets the ideal ordering process, from configuration to payment, to be done online, saving time for the customer._ ImageWatch A roadmap of future product release plans made available to large enterprise customers to help them plan their own IT strategies. Dell re immerseed its Premier Pages as DellPremier.com in September 2000 in the U.S with a new look and better navigation tools.Retention and GrowthService and support are unremarkably quite an expensive and labor-intensive activity for PC companies, which need to provide technical support for complicated systems with a wide range of austereware and software configurations. Dell has an advantage here because most of its business is with large organizations that have their own MIS departments and technical help desks to support users. Home and small business support is usually provided directly to the end user, and costs much per PC to provide. Online support was originally developed by the Support Technology Online (STO) team, which grew up in the HSB (home and small business) segment as support.dell.com. In late 1999, Dell created separate STO groups for relationship and transaction customers, each part of those groups service organizations.Dell offers several service tools online. These are available online to home and small business customers at support.dell.com, and to relationship customers on the DellPremier.com extranet_ lodge status tracking Once an order is placed by the customers, they can track it until it is delivered._ Resolution Assistant A software which is pre-loaded on a Dell PC that gathers information and sends it to a Dell technician when the customer faces a problem. The information is matched a dispatchst an automated knowledge base. Whenever possi ble, a MAP, an executable module that automates resolution, is sent to the PC and the fix is done automatically. Resolution Assistant reduces the length of service calls and improves accuracy in diagnosis._ Dell Knowledge Base A Dell database including product information, frequently asked questions, third party knowledge and other relevant documents specific to a particular Dell product._ Ask Dudley A earthy language searchable database of technical information which uses a customized version of the Ask-Jeeves search engine._ lodge Library Downloadable drivers, utilities and other updates for Dell PC systems._ Dell Software Tips -A subroutine library of hints and tips for operating systems and office applications._ Pro-active services Pro-active notification services on warrantee status, system age related information, file drivers, and the order status._ Dell Talk-a monitored society forum for Dell customers to share information. Dell has built a federation where its cus tomers and loyalists can help each other with technical problems and questions. Dell doesnt shun the discussion on the forum, but monitors it regularly to ensure accuracy. If any user gives out incorrect information, Dell intervenes with the correct information. The users of this service are closely equally divided between relationship and transaction customers.With the launch of Dell Premier Support.dell.com in September 2000, Dell renamed its Help Tech service as Premier Support for relationship customers. Technical Support for corporate and public sector clients is handled by the Relationship Support Technology Online (STO) group. The autochthonic customers for the Relationship STO are those exclusives that support the end users belonging to corporate and public sector. This includes the personnel from help desks, MIS departments, IT professionals and technicians. Dells relationship customers have access to all of the online tools available to HSB customers, and also have cus tomized applications relevant to their account for multiple systems and platforms. Unlike individual users, help desks and MIS organizations must deal with many systems, and with specific problems that arise from networking and client-server environments. For just about large accounts, Dell itself may act as the help desk function for Dell equipment, as Dells technicians and online offers have rich experience in troubleshooting and diagnose system issues.Recently in February 2008, Dell launched its ProSupport portfolio of services. In this new framework, customers are able to self-identify the type of customer they are end users of IT professionals. Once the customers have self-identified, they are able to choose the features they need in the support package, thusly customizing the support experience to their specific needs.The customer profile and history is very important in providing service and support. If the user enters a customer number or system identification number, h e or she can get a personal support site that has the machine configuration and the history of what has happened with that machine since it was bought. The support strategy is based on what Dell calls practical(prenominal) integration- getting customers closer to the knowledge, and inside out/outside in-giving the internal technicians the same set of tools and knowledge content as the outside customer. Dell gives customers a choice of venues for support, including phone and online support. They like citizenry to use the web, but dont force them to. The breakdown of help incidents for HSB customers as of mid-2000 was as follows_ 37% of incidents use the web alone for support_ 13% use both web and phone_ About 50% use the phone aloneDell finds that people who buy a PC online are more(prenominal) likely to get service and support there, while people who buy by phone will use phone service.Synchronizing Marketing EffortsThe sales and marketing efforts of Dell are organized around the evolving needs of its customers. Its direct business homunculus provides direct communication with its customers allowing it to refine its products and marketing programs for specific customer groups. Customers may offer suggestions for current and future Dell products, services, and operations on an interactive portion of its website called Dell IdeaStorm. This constant flow of communication allows Dell to rapidly gauge customer satisfaction and target new or existing products.For instance, Dell used a concept called free-range marketing3 allowing the community to drive the excitement and story about the new product, to create a buzz in social media using blogs, forums, communities etc. for the launch of their Inspiron 910 in September 2008.Updating Customer ValueDell interacts with more than 3 million customers every day, so it made sense for it to create a community to capture feedback from both customers and its 80,000 employees. Dell launched IdeaStorm, an interactive portal, to let customers share ideas that influence product development, services, and operations. Within the freshman week, IdeaStorm had collected more than 500 ideas within the first month, it had 2,500 ideas.4Customer feedback on IdeaStorm led the company to build select consumer notebooks and desktops preinstalled with the Linux platform. Dell also decided to continue offering Windows XP as a preinstalled operating system option in answer to customer requests.Dell also launched EmployeeStorm, a secure community employees can use to post ideas regardless of their position within the company. In the first 2 weeks, the company gathered more than 700 ideas. EmployeeStorm breaks down the silos typical in corporate life and increases collaborationSustaining Customers through Connected RelationshipsValue set upDells core value chain for its PC business is different from that of a traditional value chain. Like others, it concentrated on building and selling PC systems, relying on others to supply components, software and services. However, it sold directly to the end user, cutting out the distributor and reseller.

Being in direct hang with the customer requirements, Dell controls the flow of information to its business partners who provide the unquestionable service. As shown in Figure 4, all the information flows are channeled through Dell.The close physical in tegration of Dell with its business partners and suppliers. The suppliers are normally located close to the plant and their personnel are located on the plant floor ordering material from their warehouse, based on information on Dells extranet. Such integration of material and information flow reduces line of descent costs and creates an efficient supply chain, ultimately availing the end customer in the form of lower prices.The importance of internet and other electronic communication theory in allowing Dell to coordinate the web of close relationships through a constant flow of information between Dell and its partners. For example, if a customers hard drive crashes, the information travels from Dell technical support into Dells internal service and support systems. A new hard drive is ordered and dispatched to a Dell service provider, which sends a service engineer to install the drive. The information about the drive that crashed enters Dells databases and is conveyed to the supplier and plant that provided it for corrective actions.Customer gaietyFor well-designed e-commerce services, the cost savings are not necessarily thought to go along with customer satisfaction. However, Dell has demonstrated that not only does it bring through money by selling directly on Internet, but also satisfies its customers better than any other sales model. Many business customers of Dell see Premier.Dell.com as a valuable management tool, helping their get and IT departments to control purchasing decisions and enforce technology standards.Some customers (like Boeing) have integrated the Dell.Premier.com with their own ERP systems to allow online purchasing, making the ordering process much easier and more efficient for them. Not just purchasing, but also financial and IT departments of the customers benefit from Dells ability to provide a history of their purchases from Dell. All such benefits lead to better satisfaction among Dels core customer group of large busin ess enterprises.While it is difficult to relate customer loyalty and repeat sales directly to the Internet and ecommerce, there is strong evidence that the Dell Premier.com services are a factor in helping Dell gain repeat business and achieve sole supplier status with roughly large customers. Some of this is from the convenience provided by Premier services and some from customer lock-in created by the electronic linkage of business processes between Dell and its customers.In a 2007 survey, Forrester5asked 565 PC decision-makers at North American and European enterprises about their satisfaction with their primary PC supplier on various parameters. The performance of Dell and its main competitors on these parameters is shown belowDellHPLenovoOverall fruit features44%38%46%43%Product quality51%49%59%52%Price43%38%33%40%Product support46%31%46%43%Business relationship37%27%45%37% reduplicate purchase of desktops86%74%71%-NA-Repeat purchase of laptops89%75%75%-NA-From the table, it i s quite evident that Dell leads the industry on Price and Product support. It is rated on par with Lenovo on Product features and Product quality, however, it lags behind Lenovo on the key parameter of business relationship. The survey found that the most likely reason for this is a escape of communication, combined with rotating account representatives. Another reason was the absence of a product roadmap which would help the customer managers to prepare their corporate IT environment for the next few years.However, Dell scores very highly on a comminuted indicator of customer satisfaction i.e. a repeat purchase. The enterprise buyers gave capacious thumbs up to Dell on this front, with 86% ready to repeat purchase of desktops and 89% for laptops.CONCLUSIONSDell has performed admirably on its efforts towards ongoing Customer Relationship Management. It has developed efficient systems and processes for customer acquisition, retention and growth, using online tools such as Premier. Dell.com, ProSupport and IdeaStorm. Therefore, many of the concepts discussed by Anderson and Narus in Business Market Management are substantially demonstrated in the case study of Dells CRM process.There are many lessons learned from Dells experience. These lessons can be transferred to other companies in the industry. run across better customer service is offered.Dell has become an industry leader in service and reliability. Dell has used CRM to its advantage. This has instilled trust into their customers. By custom-building a computer that the customer desires, this has created a very strong relationship with the customers. accomplish technology in a phased fashionDell tested key tasks in each of its regions prior to deployment. It set-up mock environments to develop, test, and support the i2 systems in patches without disrupting the live version. Dell was able to bring on one piece of the i2 system at a time. As one part became more efficient, so Dell added other components i n stages. Dell ensured that each stage of the process performed well and allowed for future growth before rolling out the entire system. This minimized the risk, while at the same time increasing efficiency. break down the connection from the customer to the supplierDell was able to extend its build-to-order model from suppliers to the customer while continuing to maximize operational efficiency and customer satisfaction. Customers were able to save money while being able to purchase a customized machine because Dell passed on the savings, which resulted from efficient inventory management, no excess inventory or inventory shortages. It was able to share, in real-time, information with suppliers about customer demands and buying patterns.

Three Parent Families: Advantages and Disadvantages

Three Pargonnt Families Advantages and DisadvantagesJoana Murtinheira FaustinoA controversial transmittable handling was authorize in Britain and now the first s make waterr with three contagious p atomic number 18nts throne be born in 2015. The process will all(prenominal)ow that women affected by devastating hereditary diseases to have rosy fryren. However this social occasion will open the window of desoxyribonucleic acid modification in earthly concern something that was long ago decided as unethical. Is this a real breakthrough treatment or crossing a dangerous boundary?The execution aims to prevent mitochondrial diseases, involving lack of energy, muscular dystrophy, blindness, brain disorders, heart failure and remainder in the most extreme scales. Defective mitochondria affect one in every 6500 babies and research suggests that the diseases shag be prevented by using mitochondria from a conferrer en. There are two mathematical methods the embryo right and the egg repair. In the embryo repair approach both ballock (mothers and donors) are fertilised with sperm and the parents pronuclei, which contain genetic knowledge, is swapped with the donors one and this final profound embryo is implanted into the womb. The egg repair involves taking the nucleous of the egg with damaged mitochondria and inserting it into the cytoplasm of the donors egg which has had the majority of the genetic material removed, but still contains healthy mitochondria. Then the resulting egg is fertilised by sperm.As mitochondria have their own DNA, the resulting baby of this procedure would have DNA from two parents and a small tot from a third donor. This genetic modification raises major ethical concerns for a lot of wad. According to consequentialism people should do what produces the greatest amount of trustworthy consequences. It is known that with this procedure, these women would be able to have genetically associate healthy baberen. However, is thi s consequence strong enough to justify the beginning of human genetic modifications? Which way conveys to the greatest amount of good consequences?Since it is an invasive manipulation of embryos on that point are risks associated. It is not possible to assure that new diseases would not let out of this treatment due to some relation between DNA of mitochondria with the nucleous DNA, for example. If the procedure is relatively new, not much information close long-run health effects are known. Therefore, no health check benefits would emerge for the nestling or the mother.The mother would be able to have genetically related healthy children, which represents a social benefit to her, not a medical one. As the DNA swap takes place at the germ business concern the donors DNA would pass on to any future(a) generations down the female nervous strain and not only to this first child Thus, the treatment would represent a way of stopping the disease of organism passed on to their fu ture generations. Nevertheless, it would also be changing the genetic information of the family that it will always have the donors DNA included. Would this have implications for future persons?Opponents to this treatment claim that are other options that may be considered for these cases such as adoption or egg donation. Is adoption real an option? People that desire to have their own children usually do not see adoption as option. It will not be a good relationship between parents and child if the adopted child is seen as a second option and not a desired one. Through egg donation parents are not genetically related to the child and this treatment would allow them to be.Another of the major concerns related to this technique is that the next step would be full altered genetic babies since the line of performing modifications in human DNA would be already pass over with this procedure. It has been described as a slippery slope for society that can lead to other forms of genetic modification.There are several questions that imply to be answered. Would the child have identity problems since it would have genes from three people? What would be the role of this second mother? Would she have the same condition as other egg donors or could be considered a court-ordered parent?Apparently there was not enough debate about this topic. usually, people get very afraid of these pioneer changes that can be one small step away from a worst case scenario. Moreover, it is easy for people to associate genetic modifications with stories described in allegorys or cinema, as dystopian societies are depicted several times. A dystopia 1,2 is a place that is in some important way undesirable or frightening it is the opposite of utopia. Dystopias are often temperized by dehumanization, totalitarian governments, environmental disaster, or other characteristics associated with a cataclysmic decline in society. Usually they appear to draw attention to real-world issues regard ing society, politics, economics, environment, religion, psychology, ethics, and science and technology, which if unaddressed could potentially lead to such a dystopia-like condition. Two examples that address to genetic modifications are run New World and Gattaca.Brave New World 3, a novel that was also adapted to a movie, describes how developments in reproductive technology, combined with others, are responsible for profoundly changes in society. Natural reproduction is no long-range done. Instead, children are produced in hatcheries and conditioning centres and divided into castes and designed to occupy shape positions in the social and economic life. There are five castes of import and beta are able to develop naturally but da Gamma, delta and epsilon are manufactured to have arrested development in intelligence or physical growth.In the reality described in Gattaca 4 (the title is establish on the first letters of guanine, adenine, thymine, and cytosine, the four nucleobas es of DNA) children are conceived through genetic manipulation to guarantee they possess the best hereditary traits of their parents. The main character was conceived outside the program and fights to overcome genetic discrimination. Characters battle with society and themselves to understand what their place in the world is and who they are destined to be agree to their genes. This way, the movie is able to draw attention over reproductive technologies and the possible consequences of such technological developments for society.By allowing this treatment, are we going towards a dystopian society like these ones described?On the other hand, despite all the concerns that the treatment involves should the evolution of science be stopped? If it would be fully regulated and the consequences well studied, why should this treatment be stopped? wherefore should not these mothers be allowed to have access to this known treatment? some people have the desire to have their DNA related chi ldren and this treatment seems the only option for these women, also stopping the disease of being passed on to their future generations.Medical researchers defend that the debated modification does not affect vestigial DNA, the one that will determine individuals characteristics such as facial features or eye colour. Therefore what it is under discussion are not designed babies but a treatment of several diseases.ReferencesMerriam-Webster (2014). Merriam-Webster.
