He was an educator of tenet and depleted clasp in Germany where he was acquainted with new progresss in mental science and cultural logical order. He had a significant impact and had an enormous effect to the overview of society, implosion, the division of work, solidarity and confidence and has as often as possible been thought of and viewed as the laminitis of expert human science. Durkheim principal distributed his build of anomy in his book â€Å"The Division of Labor in Society† ( 1893 ) . In his book he showed guidelines of how connection between individuals was crumbling and how they couldn't indicate how to relate and communicate with one another. Accordingly he accepted that anomy was where the viewpoints of practices are non plainly characterized and there is a separate in the framework which is known as normlessness.

In criminology the develop of anomy is that the single decides to execute condemnable activities since this individual accepts there is no ground non to make so. The individual is ordinarily estranged and detached, feels useless or immaterial and thinks it is unpointed and vain to look for and achieve whatever else as it is a misuse of clasp and endeavor. Along these lines typically this individual conflicts with the standard and estimations of society and sees there is no other interchange than to go associated with condemnable and rebellious exercises. Take a situation which is classed as the standard in a functionalist society: the region gives guidance to kids, income upgrades are paid by the guardians/groups of these children which are in twist used to finance their guidance and improvement. Regularly these children grow up great instructed and ready to acquire work and achieve their finishes profession insightful. They become statute staying residents, have an occupation, pay their income upgrades, settle down have their ain children thus the mood proceeds. In the United Kingdom this is the standard for the greater part of the populace and society by and large presents. Anyway take the situation where anomy is associated with different words the fortunes the child is being raised and populating in is non the standard in this situation: The child goes to a failing to meet expectations school in a hapless nation where the heft of individuals are populating on region benefits. The child does non see the point in making a trip to class and only goes to the exposed insignificant total of clasp. The child leaves school at the soonest possibility and is non energized by family unit and companions to go on in guidance. The nation the child lives in has high offense rates and a group human progress. This child turns into a youthfu l who sees their solitary opportunity to get on in life is to fall in the nearby pack and go engaged with them and participates in offense. The guardians are jobless, uninvolved and have condemnable narratives so the pre-adult considers the to be as their family. The juvenile turns into an adult, has just spent clasp in a youthful offender’s foundation and has no chance of securing an occupation. This adult is presently unemployable and feels useless, irrelevant and has no feeling of way and consequently falls into an existence of offense. In this occasion the immature got associated with offense since they felt there was no other choice or chance accessible to them. This first outline shows how the develop of anomy is significant in the public eye today. In the United Kingdom sensibly late there have been two cases which show the develop of anomy is pertinent in current twenty-four hours society. The anomies being alluded to is open violences and fights where revolting is an outcome of anomy and a signifier of anomy. Revolting by English and Welsh residents is a legal offense in England and Wales and is recorded in Sections 1 to 5 of the â€Å"Public Order Act 1986† . An open brutality as characterized by the â€Å"Oxford English Dictionary† is ‘A wild or troublesome bother made by a major figure of individuals. In this outline the quickening agent for the open violences in Tottenham was non the shot of Mark Duggan on the 4ThursdayAugust 2011 as was introduced by the essentialness. The existent reason for the open violences was the encounter between a demonstrator and a cop outside the constabulary station in Tottenham at 7.20pm on Saturday sixth of August. These activities caused a territory of anomy that permitt ed the demonstrators the capacity to take out their thrashings in a way that does non match to cultural standards and this was the beginning of the Tottenham open violences in North London. At the point when society turns out to be progressively natural and complex like present day twenty-four hours society is individuals are not, at this point dependent on each other and consequently cultural bonds become unoriginal. In this delineation there was a separation of cultural standards where standards were not, at this point ready to order the activities of individuals in the public eye. Durkheim himself saw that cultural times of break for delineation financial downturn similar to the example in 2011 was as often as possible answerable for more prominent anomy with higher degrees of offense, implosion and distortion. With notice to the Tottenham open violences in North London there is an unmistakable relationship with Durkheim’s develop of anomy. The showdown among demonstrators and the constabulary was the quickening agent to get down the open violences yet it was non the reason which was a corporate develop of grounds and issues. With the state in a monetary emergencies and high evaluations of fomentation in the network because of the shot of this guiltless youthful grown-up male the degrees of estranged conduct were incredibly expanded. It could be contended that the standards of the situation had separated, as there was disarray about whether or non Mark Duggan had even taken shots at the constabulary. As the open violences heightened, we can other than partner to the way that there was a lack of guidelines to direct individuals, and thus, normlessness broke out, which as Durkheim expressed prompted freak conduct. This offered ascend to personal circumstance and enticed people to fall in the open violences on the balance that it is difficult to get a man in a major riffraff. Freak conduct, for example, burglary and â€Å"copycat† revolting in di fferent metropoliss in the state other than happened expanding the degrees of distanced conduct. The threatening speed with which the power spread from London to other huge metropoliss this clasp was implicative of an undeniably increasingly mind boggling and significant feeling of cultural alienation and disengagement. Britain’s upset and profoundly inconsistent society is one in which numerous individuals feel they have no intrigue or from now on, this sentiment of defenselessness energizes anomie. The other ongoing outline of estranged conduct applicable to cutting edge society was a progression of understudy dissents in 2010 in the United Kingdom with the central fights in London. The points of these fights were to restrict arranged payment cuts in farther guidance and the increments in understudy education costs. The quickening agent for this situation was the outcomes of the specialists reappraisal of help for higher guidance in England. Orchestrating to student bunches guarantees made by lawmakers during political decision runs had been broken. Higher guidance would go less come-at-capable for youthful individuals. Future students would plug up with high obligations holding to take care of these obligations over longer periods in cut go forthing them under water for longer during their large life. The perceptual experience was that proposed slices to training were unnecessary and would harm the nature of higher guidance. It would give understudies higher obligations, and r un guarantees made by legislators were seen as broken guarantees. The primary significant dissent composed by the National Union of Students ( NUS ) and the University and College Union ( UCU ) included up to fifty 1000 demonstrators who walked through cardinal London by the by a few hundred remaining the March to assault and occupied the Conservative Party focal office. The splitting ceaselessly bunch caused a partition inside the understudy movement for using such strategies each piece great as animadversion and horrible judg

Radio Waves :: essays research papers

Radio Waves      In the advanced society, radio is the most broadly utilized vehicle of broadcasting and electronic correspondence : it assumes a significant job in numerous regions for example, open security, mechanical assembling, handling, farming, transportation, amusement, national barrier, space travel, abroad correspondence, news detailing and climate guaging. In radio stations, they utilize the radio waves which can be the two microwaves and longer radio waves. These are transmitted in two different ways: abundancy adjustment (AM ) and recurrence balance ( FM ). These two sorts of wave have numerous distinctions.      Radio waves are among the numerous kinds of electromagnetic waves that travel inside the electromagnetic range. Radio waves can be characterized by their recurrence (in hertz, after Heinich Hertz , who originally delivered radio waves electronically), which is number of times they go through a total cycle for every second; or by their frequency, which is controlled by the separation (by meters) that is gone from the peak of one wave to the peak of the following.      Radio frequencies are estimated in units called kilohertz, megahertz, and gigahertz. (1 kilohertz = 1000 hertz : 1 megahertz = 106 hertz, 1 gigahertz = 109 hertz). Every single radio wave fall inside a recurrence scope of 3 kilohertz, or 3000 cycles for each second to 30 gigahertz. Inside the scope of frequencies, radio waves are additionally separated into two gatherings or groups, for example, low recurrence ( VLF 10-30 kHz ), low recurrence (LF 30-300 KHz), medium recurrence ( MF 300-3000 KHz), high recurrence ( HF 3-30 MHZ) and high recurrence ( VHF 30-300MHZ).      Amplitude tweak is the most seasoned strategy for transmitting voice and music through the wireless transmissions is by plentifulness tweak. This is practiced by joining a sound wave from a mouthpiece, tape, record, or CD with a "carrier" radio wave. The outcome : a wave that transmits voice or programming as its sufficiency ( force ) increments and diminishes. Plentifulness regulation is utilized by station broadcasting in the AM band and by most worldwide short wave stations.      Frequency tweak is another approach to pass on data, voice , and music on a radio wave is to marginally change, or regulate, the recurrence. The principle preferred position of FM broadcasting is of it is sans static. Be that as it may, the disadvantage to FM is since the recurrence is fluctuated, station occupies more space on the band. Recurrence regulation is, obviously, utilized on the FM band. What's more, it is utilized for "action band" and ham transmission in the VHF/UHF recurrence go.      In adequacy balance, what is altered is the sufficiency of a transporter wave on one explicit recurrence.

Carbon Tax Carbon Taxes Essay - 720 Words

Carbon Tax A carbon tax is a fee on the emissions released from burning fossil fuels. According to carbontax.org, it is an â€Å"antidote to rigged corporate energy pricing†. So unlike cap-and-trade, it does not â€Å"create complex and easily gamed ‘carbon markets’ with allowances, trading and offsets†. It is implemented by placing a tax on carbon emissions. So carbon that is within products such as plastics will not be taxed as it does not get burned and release emissions into the atmosphere. The tax will be placed at the point where the fuel is extracted, imported, supplied, and consumed. As with all implementations, it will have its benefits and drawbacks. Benefits Having a carbon tax will encourage further research and development of more efficient alternatives. With the extra cost of using fossil fuels, companies will look into alternative sources like solar and wind for their power needs. This tax will also be a monetary incentive on a local level to push consumers to look for alternatives. In turn, this lowers emissions, saves them money, and has a positive impact to the environment. The revenue collected from the tax could be directed to funding for those alternative energy sources. More funding means more opportunity to develop effective alternative sources, because today, fossil fuels are simply more powerful, effective, and reliable.

Barilla Essay Research Paper Barilla SpA AGiorgio free essay sample

Barilla Essay, Research Paper Barilla SpA ( A ) Giorgio Maggiali was going progressively frustrated. As manager of Logistics for the universe # 8217 ; s largest pasta manufacturer, Barilla SpA, he was acutely cognizant of the turning load that demand fluctuations imposed on the company # 8217 ; s fabrication and distribution system. Since his assignment in 1988 as Director of Logistics, he had been seeking to do headroom on an advanced thought proposed by Brando Vitali, who had served as Barilla # 8217 ; s manager of Logistics before Maggiali. The thought, which Vitali called Just-in-Time Distribution ( JITD ) , was modeled after the popular # 8220 ; Just-In-Time # 8221 ; fabricating construct. In kernel, Vitali proposed that, instead than follow the traditional pattern of presenting merchandise to Barilla # 8217 ; s distributers on the footing of whatever orders those distributers placed with the company, Barilla # 8217 ; s ain logistics organisation would alternatively stipulate the # 8220 ; appropriate # 8221 ; bringin g quantities-those that would more efficaciously fitting end consumer # 8217 ; s needs yet would besides more equally administer the work load on Barilla # 8217 ; s fabrication and logistics systems. For two old ages Maggiali, a strong protagonist of Vitali # 8217 ; s proposal, had tried to implement the thought, but now, in the spring of 1990, small advancement had been made. It seemed that Barilla # 8217 ; s clients were merely unwilling to give up their authorization to put orders as they pleased ; some were even loath to supply the elaborate gross revenues informations upon which Barilla could do bringing determinations and better its demand prognosiss. Possibly more disconcerting was the internal opposition from Barilla # 8217 ; s ain gross revenues and selling organisations, which saw the construct as impracticable or unsafe, or both. Possibly it was clip to fling the thought as merely impracticable. If non, how might he increase the opportunities that the thought would be accepted? Company Background Barilla was founded in 1875 when Pietro Barilla opened a little store in Parma, Italy on via Vittorio Emanuele. Bordering the store was the little # 8220 ; research lab # 8221 ; Pietro used to do the pasta and staff of life merchandises he sold in his shop. Pietro # 8217 ; s boy Ricardo led the company through a important period of growing, and in the 1940s, passed the company to his ain boies, Pietro and Gianni. Over clip, Barilla evolved from its modest beginnings into a big, vertically incorporate corporation with flour nothings, pasta workss, and bakery-product mills located throughout Italy. SPA ( Societa per Azioni ) can be translated as # 8220 ; Society for Stockholders # 8221 ; and interpreted as In a crowded field of over 2,000 Italian pasta makers, Pietro and Gianni Barilla differentiated their company with a high quality merchandise supported by advanced selling plans. Barilla revolutionized the Italian pasta industry # 8217 ; s selling patterns by making a strong trade name name and image for its pasta, selling pasta in a certain -cardboard box with a recognizable colour form, instead than in majority, and puting in large-scale advertisement plans. In 1968, to back up the double-digit gross revenues growing the company experienced during the 1960s, Pietro and Gianni Barilla began building of a 1.25 million square metre state-of-the art pasta works in Pedrignano, a rural town 5 kilometer outside of Parma. The cost of this monolithic facility-the largest and most technologically advanced pasta works in the world-drove the Barillas deeply into debt. In 1971, they sold the company to the American multi-national house W. R. Grace, Inc. Grace brought extra capital investing and professional direction patterns to the company and launched an of import new Mulino Bianco ( # 8220 ; White Mill # 8221 ; ) line of bakeshop merchandises. Throughout the 1970s, confronting hard economic conditions -and new Italian statute law that both capped retail pasta monetary values and increased cost-of-living allowances for employees, Grace struggled to do its Barilla acquisition wage off. In 1979, Grace sold the company back to Pietro Barilla, who by so had secured the # 8216 ; necessary financess to buy it. The capital investings and organisational alterations that Grace had brought to Barilla, combined with bettering market conditions, helped Pietro Barilla launch a successful return to the company. During 1980s, Barilla enjoyed an one-year growing rate of over 21 % ( see Exhibit 1 ) . Growth was realized through enlargement of bing concerns, both in Italy and other European states, every bit good as through acquisition of new, related concerns. In 1990, Barilla was the largest pasta maker in the universe, doing 35 % of all pasta sold in Italy and 229/6 of all pasta sold in Europe. Barilla # 8217 ; s portion in Italy comprised its three trade names: the traditional Barilla trade name represented 32 % of the market, the staying 3 % of market portion was divided between its Voiello trade name ( a traditional Neapolitan pasta viing in the costly section of the semolina pasta market ) and its Braibanti trade name ( a high-quality, traditional Parmesan pasta made from eggs and semolina ) . About half of Barilla # 8217 ; s pasta was sold in northern Italy and half in the South, where Barilla held a smaller portion of the market than in the North but where the market was larger. In add-on, Barilla held a 29 % portion of the Italian bakery-products market. In 1990, Barilla was organized into seven divisions: three pasta divisions ( Barilla, Voiello, and Braibanti ) the Bakery Products Division ( fabricating medium to hanker shelf-life bakeshop merchandises ) , the Fresh Bread Division ( fabricating really short shelf-life bakeshop merchandises ) , the Catering Division ( administering bars and frozen crescent rolls to bars and pastry stores ) , and the International Division.

Addition of NaoH solution to Cu (NO3)2 gave a dark blue solution. After boiling the Solution gotten above, I sieved out the water and had CuO(s) left in the Beaker. The addition of HCl (drop wise) to CuO gave a yellowish green solution. When NH4OH solution was added it gave a yellowish green solution. I added 15ml of 1. m H2SO4 to yellowish green solution co I suspect the copper complex to be [Cu (H2O) 6]2+, since it gave a blue-green solution. When zinc dust was added to The solution a shiny reddish brown metal was formed. Discussion It is observed that copper was conserved throughout the experiment. And despite The conservation of copper in the reaction, the percentage recovery of copper is less than 100%. i had 80% of copper recovered from Cu (NO3)2. After pouring out the supernatant some CuO clung to the wall of the beaker. Therefore, the HCl did not dissolve all of the CuO. This unreacted CuO causes a decrease in the mass of Cu recovered. Also, I forgot to scrunch the copper formed before drying. The clumps of copper might contain some water which increases its mass when weighed. It is necessary to synthesize the various compounds one after the other in order to recover copper metal because, it is not possible to get copper metal because it is not possible to get copper directly from Cu (NO3)2. all these phases are needed to be passed through. When zinc is added a zinc hexaquo complex is formed from the bonding of Zn2+ with six molecules of water. The addition of H2SO4 causes the Cu2+ from Cu(OH)2 to combine with water molecules to form [Cu(H2O)6]2+. The Cu(OH)2 is gotten from reaction of CuCl2 with NH3. The percent yield depends on whether certain reactions were completed or not. my percent yield 80% is affected by incomplete reaction of CuO with HCl. During the decomposition of Cu (OH) 2, some Cu might have been lost in heat form. Also when transferring the copper from the Buchner funnels into the weighing bottle, some copper metal were stuck to the funnel. This would also decrease the percent yield of copper gotten. Conclusion Given the concentration of Cu (NO3)2 and volume as 10. 0ml, the percent recovery of copper gotten from synthesis of copper compounds is 80%.

Nethercott and M. Evelynn Walton Department of Physics, University of Utah, Salt Lake City, 84112, UT, USA (Dated: March 6, 2013) Using a simple pendulum the acceleration due to gravity in Salt Lake City, Utah, USA was found to be (9. 8 +/- . 1) m/s2 . The model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. The model was supported by the data using a linear ? t with chi-squared value: 0. 7429 and an r-square value: 0. 99988. This experimental value for gravity agrees well with and is within one standard deviation of the accepted value for this location. I. INTRODUCTION The study of the motion of the simple pendulum provided valuable insights into the gravitational force acting on the students at the University of Utah. The experiment was of value since the gravitational force is one all people continuously exp erience and the collection and analysis of data proved to be a rewarding learning experience in error analysis. Furthermore, this experiment tested a mathematical model for the value of gravity that that makes use of the small-angle approximation and the proportional relationship between the square of the period of oscillations to the length of the pendulum. Sources of error for this procedure included precision in both length and time measurement tools, reaction time of the stopwatch holder, and the accuracy of the stopwatch with respect to the lab atomic clock. The ? nal result of g takes into account the correction for the error introduced using the approximation. There are opportunities to correct for the e? cts of mass distribution, air buoyancy and damping, and string stretching[1]. Our results do not take these e? ects into account at this time. A. Theoretical Introduction The general form of Newton’s Law of Universal Gravitation can be used to ? nd the force between any two bodies. FG = ? G mME ? 2 r RE (1) 2 On earth this equation can be simpli? ed to F = ? mg? with the value r GME 2 RE taken to be the constant g. The value of gravity in Salt Lake City (elev. 1320 m) according to this model is: 9. 81792 m/s2 [3][4][5]. The simple pendulum provides a way to repeatedly measure the value of g.

F = ma = mgsin? can be written in di? erential form ? g ?=0 L The solution to this di? erential equation relies on the small angle approximation sin? ?: (2) (3) ? for small ?(t) = ? 0 cos( g ) L (4) 3 The Taylor expansion ?(t) ?o [1 ? gt2 g 2 t2 ] + 2L 4! L2 (5) allows us to take the ? dependence out of the equation of motion. Taking the second derivative of the approximation gives the following: g ? ? = 0 L (6) 0 g g g g + ? = 0 =? ?0 = ? L L L L g L, (7) 4? 2 T2 ? We know from the ? rst derivative ? = ? so it follows that since ? 2 = = g L ?0 . g 4? 2 =? 2 L T (8) From the initial conditions it is also clear that the initial amplitude ? is equal to ? 0 and so the linear relationship between length L and period T 2 can be expressed as T2 = . 4? 2 L g (9) Using the small angle approximation introduces a small systematic error in the period of oscillation, T. Fo r instance the maximum amplitude angle ? for a 1 percent error is . 398 radians or 22. 8 degrees; to reduce the error to 0. 1 percent the angle must be reduced to . 126 radians or 7. 2 degrees. This experiment used an angle of about 10 degrees and that introduced an error of 0. percent. The calculations for the systematic error are found in the Appendix. II. EXPERIMENTAL PROCEDURE A. Setup As seen in Figure 2, the pendulum apparatus was set up using a round metal bob with a hook attached to a string. The string passed through a hole in an aluminum bar, which was attached to 4 the wall. The length of the string could be adjusted, and the precise point of oscillation was ? xed by a screw, which also connected a protractor to the aluminum bar. FIG. 2: Experiment setup. Length measurements for the pendulum were taken using a meter stick and caliper. The caliper was used to measure the diameter of the bob, having an uncertainty of 0. 01cm. The total length was measured by holding the meter stick up against the aluminum bar, and measuring from the pivot point to the bottom of the bob. The bottom was determined by holding a ruler horizontally against the bottom of the bob. The meter stick measurements had an uncertainty of 0. 2cm. Time measurements were made using a stopwatch. For measuring the ? rst swing the starting time was determined by holding the bob in one hand and the stopwatch in the other and simultaneously releasing the bob and pushing Start. The stopping point, and starting point for the second oscillation, was determined by watching the bob and pushing Stop/Start when the bob appeared to reach the top of the swing and stop. The precision of the stopwatch was compared with an atomic clock by measuring several one second intervals. The precision of the time measurements were also a? ected by reaction time and perception of starting and stopping points of the person taking the measurements. Time measurements were taken by the same person to keep the uncertainty in reaction time consistent. 5 B. Procedure To determine which measurements weremost reliable, data was taken for the period of the ? rst oscillation, second oscillation, and twenty oscillations (omitting the ? rst) at a set length of 20. 098 cm. The length was then adjusted to 65. 5647 cm, and the same measurements were taken. To see the limits of the small angle approximation measurements of 20 oscillations (omitting the ? rst) at a ? xed length of 60. 1605 cm were taken by beginning the swing at angles of 5, 10, 20, and 40 degrees. Measurements were then taken for 20 oscillations (omitting the ? rst) for lengths of 20. 098, 26. 898, 32. 898, 60. 1605, 65. 6467, 74. 648, 89. 848, 104. 548, 116. 498, and 129. 898 cm at a starting angle of about 10 degrees. III. RESULTS The result for g obtained from both measured values of L and T 2 from equation 9 as well as from the slope in the Linear Fit model (Figure 4) agree very well with accepted results for g. The precision could be improved by corrections for e? ects of mass distrib ution, air buoyancy and damping, and string stretching[1].

DISCUSSION By measuring 20 oscillations the average period is determined by dividing by 20 and this helps reduce the error since the error propagation will provide an uncertainty in the period that is the uncertainty in the time measurement divided bytwenty. From Table 1 and Figure 3 the limits of the small angle approximation are shown. Between 10 and 20 degrees the theoretical model begins to breakdown and the measured period deviates from the theoretical value. Measurements taken at less than 10 degrees will be more accurate for the small angle approximation model that was used. Two methods were used to calculate a value of g from the data. The ? rst method used to calculate a value of g from the measurements taken is making the calculation from each of the 6 1. 62 1. 60 T (sec) 1. 58 1. 56 1. 54 0 5 10 15 20 25 30 35 40 45 Angle (degrees) FIG. 3: Period dependence on angle as ? increases from 3-40 degrees.

The slope of this line was used to calculate g. en di? erent lengths, using the measurements shown inTable 7 of 20 oscillations at the di? erent lengths, and taking the average. The calculated average g was (9. 7 + / ? 0. 1) m/s2 . The second method used was applying a linear least squares ? t to the values of length and the 7 accompanying T 2 . Figure 4 shows this method and gives the values for the ? t parameters. The value of g is determined by using the slope of the line and gave a value of g to be (9. 8 + / ? 0. 1) m/s2 . Figure 5 shows that data has a random pattern and all of the error bars go through zero, which means that the data is a good ? for a linear model. 0. 10 0. 05 Residual T 2 0. 00 -0. 05 -0. 10 0. 2 0. 4 0. 6 0. 8 1. 0 1. 2 1. 4 Independent Variable FIG. 5: Random pattern of Residual T 2 . As discussed in the theoretical introduction, a value of g 9. 81792 m/s2 can be calculated using G, ME , and RE . The value of g varies depending on location due to several factors including the non-sphericity of the earth, and varying density. A more accurate value of g in Salt Lake City, Utah can be calculated by taking into account these e? ects. The National Geodetic Survey website, which interpolates the value of g at a speci? latitude, longitude and elevation from observed gravity data in the National Geodetic Survey’s Integrated Data Base, was used to determine an accepted value of g for Sal t Lake City, Utah, for which to compare the calculated results[7][8][6]. The accepted value for g in Salt Lake City, Utah is (9. 79787 + / ? 0. 00002) m/s2 . Comparing the two methods used to calculate g shows that the least squares linear ? t provided a value of g that is closer to the theoretical[3][4][5] and accepted[7][8][6] values of g. The calculation of g supports the small angle approximation model that was used. The linear relationship to length and period squared provided by the approximation gave a way of employing a least squares linear ? t to the data to determine a value of g. Since the calculated value was 8 within one standard deviation from the theoretical value, the model was supported. V. CONCLUSION The small angle approximation model, which gives g as being proportional to T 2 and L, was supported by the data taken using a simple pendulum. The residual of the data showed that it was a good ? t for a linear model, and the least squares linear ? t of the data had ? t parameters of chi-squared: 0. 7429 and an r-square value: 0. 99988. The value of g taken from the slope of the least squares linear ? t provided a value of g: (9. 8 + / ? 0. 1) m/s2 , which is within one standard deviation of the accepted value of gravity in Salt Lake City: 9. 79787 m/s2 [6]. The experiment was a good way of testing the small angle approximation because the period measured using di? erent starting angle s was consistent for angles less than 10 degrees. Using the small angle approximation the relationship between period squared and length was linear so a least squares linear ? t could be utilized to calculate g. The value of g calulated using the least squares linear ? t could then be compared to the accepted value of g for the location, thus verifying the model that was employed. [1] R. A. Nelson, M. G.

Time The sources of error introduced in this experiment came from the tools we used to measure length: calipers for the bob and a meter stick for the string length as well as the stop watch used to time each period of oscillation. Measuring the period had several sources of error including precision, the atomic clock benchmark, the reaction time of the experimentor, and the statistical error which was the standard deviation from the measurements taken. On the whole, the relative error in T was greater so that was the error used in the linear ? t analysis. ?T = 1 20 (? Treaction )2 + (? Tatomic )2 + (? Tprecision )2 + (? Tstatistical )2 (10) Equation 10 also takes into account the error propagation in taking the time period for twenty oscillations. This ? T is the random error; to account for the systematic error introduced by using the small angle approximation the complete solution for the period of oscillation is as follows [2]: 1 ? max 9 ? max T (? max ) = T0 + T0 [ sin2 ( ) + sin4 ( )] 4 2 64 2 (11) To ? nd the percent error introduced by the angle used in the experiment the solution in equation 11 was rearranged to give: T (? max ) ? To 1 ? max 9 ? max = sin2 ( ) + sin4 ( ) T0 4 2 64 2 (12) The angle used in this experiment was 10 degrees. Plugging that value into the right side of equation twelve gives a value of . 002967. It follows that T0 = T (? max ) 1. 002967 (13) Each of our measured values of T was corrected by this factor. To get the error for T 2 : ? T 2 = T ? T The results are found in Table 7. These values were plotted in ? gures 4 and 5. (14) 10 C. Gravity The errors in the calculations for g were determined di? erently for the two methods. The uncertainty in the least square ? t was calculated from the slope and uncertainty of the slope (see Figure 4). ?g = The calculations of g from L and T 2 used: ? g = g ( These values are found in Table 8. 4? 2 ? m m2 (15) ?L 2 ?

An atmosphere of helium would cause an organ pipe to have a higher pitch because the speed of sound is taster in helium, but since the pitch tot a tuning fork has a set frequency, the pitch will not change, 3. If you measure an interval of S seconds between seeing a lighting flash and hearing the thunder with the temperature of air being ICC, the lightning was 1715 meters away, x=mm 4.

Wavelengths may be found by measuring the difference between two successive tube lengths at which resonance occurs and will be half the wavelength. The original hypothesis for this experiment was that the speed of the sound will be greater due to the enrapture of the air being higher. In the experiment, when the water was lowered to different heights which in turn caused a change in length of the air columns. Which then allowed the tuning fork to resonant.

Lab Report Essay Example Lab Report Paper The arm may be a bent portion of the shaft, or a separate arm attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod. The end of the rod attached to the crank moves in a circular motion, while the other end is usually constrained to move in a linear sliding motion. In a reciprocating piston engine, the connecting rod connects the piston to the crank or crankshaft. Together with the crank, they form a simple mechanism that converts linear motion into rotating motion. Connecting rods may also convert rotating motion into linear motion. Historically, before the development of engines, they were first used in this way. In this laboratory we will investigate the kinematics of some simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration or kinematical restricted motions, which will discover. An adjustable slider- crank apparatus and a computer simulation will show you some effects of changing the proportions of the slider-crank mechanism on piston velocity and acceleration. Other linkages and cam mechanisms may also be used for linear- rotary motion conversion and some of these will be included in the lab Abstract The distance between the piston and the centre of the crank is controlled by the triangle formed by the crank, the connecting rod and the line from the piston to the centre of the crank, as shown in [ Figure 1 1.

From this geometry, the distance s is given by [1]: The rightmost position of P occurs when the crank and connecting rod are in line along the axis at P and the distance from O to P is I + r. Since the distance measured in the experiment uses this position as the reference location, the distance measured is given by: This means that x is a function of the crank angle O and that the relationship is not linear. Figure 1 Geometry of Crank and Connecting Rod Mechanism Procedure 1 . )III of equipments for experiment of slider crank are set in good condition. 2. )Before taking readings,we turned the crank slowly and watched the movement of the piston to make sure it moves in the correct direction 3. ) The angle of the circle, is twisted at degrees and a resulting distance that the piston moves, q is measured. The position of sliding block/slider, x is calculated 4. ) The procedures number 3 and number 4 are repeated with an increasing angle of 5 degrees until the angle of circle reaches 3600 5. ) The graph of the position of slider, against angles of circle, is plotted. Apparatus Crank and connecting rod assembly Conclusion From the experiment we can conclude that the motion of the piston will gradually approach simple harmonic motion in increasing value of connecting rod and crank ratio. Even though that is the case in this experiment we did not really get the graph as said in theory but it is almost the same. I believe that we had done something wrong while doing the experiment. The graph plotted can be shown that almost all the graphs tend to move to simple harmonic motion. The experiment was a simple one but it really needs a lot of time to take the eating.

Answer: Cell types or their structures can be distinguished from one another on the basis of the stain that is retained. Source: Microbiology A Laboratory Manual 4th Edition/ James G. Cappuccino, Natalie Sherman/ 2008/ Pages 73 Question 4: which is the most crucial step in the performance of the Gram staining procedures? Explain. Answer: Decentralization is the most crucial step of the Gram stain. Over-decentralization will result in lost of the primary stain causing Gram positive organisms to appear Gram negative. Under-decentralization will not completely remove the C.V.-I (crystal-violet-iodine) complex, causing Gram negative organisms to appear Gram positive. Source: Microbiology A Pages 74 Question 5: Because of a snowstorm, your regular laboratory session was cancelled and the Gram staining procedure was performed on cultures incubated for a longer period of time. Examination of the stained Bacillus cereus slides revealed a great deal of color variability, ranging from an intense blue to shades of pink. Account for this result. Answer: The organisms lost their ability to retain the primary stain and appear to be gram-variable. Source: Microbiology A Laboratory Manual 4th Edition/ James G.

Mycobacterium has a thick, waxy wall that makes penetration by stains extremely difficult so the acid fast stain is used because once the primary stain sets it cannot be removed with acid alcohol. This stain is a diagnostic value in identifying these organisms. MATERIALS: * Bunsen burner * Hot plate * Inoculating loop * Glass slides * Bibulous paper * Lens paper * Staining tray * Microscope METHODS: 1. Prepared a bacterial smear of M. Schematic, S. Erasures, ; a mixture of M. Schematic ; S. Erasures 2. Allowed 3 bacterial slides to air dry ; then heat fixed over Bunsen burner 8 times. . Set up for staining over the beaker on hot plate, flooded smears with primary stain-crystal fuchsia and steamed for 8 minutes. 4. Rinsed slides with water 5. Decolonize slides with acid alcohol until it runs clear with a slight red color. 6. Rinsed with water 7. Countersigned with methyl blue for 2 minutes 8. Rinsed slides with water. 9. Blot dry using bibulous paper and examine under oil immersion * Mycobacterium Schematic * S. Erasures * A mixture of S. Erasures ; M. Schematic RESULTS AND DATA USED: 1. M. Schematic, a bacilli bacteria that colored pink resulting in acid fast. 2. S. Urges, a Cisco bacteria that colored blue resulting in non acid fast. 3. M. Schematic ; S. Erasures resulted in both acid fast ; non acid fast. CONCLUSION The conclusion to the acid fast stain is that S. Erasures lacks a cellular wax wall causing the primary stain to be easily removed during decentralization, causing it to pick up the countersink-methyl blue. This results in a non acid fast reaction, meaning it is not in the genus Mycobacterium. M. Schematic has a cellular wax wall causing the primary stain to set in and not be decolonize; this results in an acid fast reaction meaning it is in the genus Mycobacterium. REVIEW QUESTIONS Question 1: Why must heat or a surface-active agent be used with application of the primary stain during acid-fast staining? Answer: It reduces surface tension between the cell wall of the embarcadero and the stain. Source: Microbiology page 79 Question 2: Why is acid-alcohol rather than ethyl alcohol used as a decontrolling agent? Answer: Acid-fast cells will be resistant to decentralization since the primary stain is more soluble in the cellular waxes than in the decontrolling agent. Ethyl alcohol would make the acid fast cells non-resistant to the decentralization. Source: Microbiology A Laboratory Manual 4th Edition/ James G. Cappuccino, Natalie Sherman/ 2008/ page 79 Question 3: What is the specific diagnostic value of this staining procedure? Answer: Acid-fasting staining represents bacteria that is pathogenic to humans Question 4: Why is the application of heat or a surface-active agent not required during the application of the counter stain in acid-fast staining? Answer: The counter stain methyl blue is only needed to give the stain its color. Source: Microbiology A page 79 Question 5: A child presents symptoms suggestive of tuberculosis, namely a respiratory infection with a productive cough. Microscopic examination f the childs sputum reveals no acid-fast rods. However, examination of gastric washings reveals the presence of both acid-fast and non-acid fast bacilli. Do you think the child has active tuberculosis? Explain. Answer: Yes, the child may have active tuberculosis. Although, acid-fast microorganisms are not easily removed and non-acid fast are. Tuberculosis represents bacteria that are pathogenic to humans, the stain is of diagnostic value identifying these organisms. Source: Microbiology A Laboratory Manual 4th Edition/ James G. Cappuccino, Natalie Sherman/ 2008/page 79 LAB EXPERIMENT NUMBER 13 The purpose of this experiment is to identify the difference between the bacterial spore and vegetative cell forms. The vegetative cells are highly resistant, metabolically inactive cell types. The endoscope is released from the degenerating vegetative cell and becomes an independent cell. MATERIALS: * hot plate * staining tray * inoculating loop * glass slides * bibulous paper * lens paper * microscope 1 . The spore stain (Schaeffer-Fulton Method) is performed on a microscopic slide by making an individual smear of the bacteria on slide and heat fixing until dry. 2. Flood the smears with malachite green and place on top of a beaker of warm eater on a hot plate, allowing it to steam for 5 minutes. 3. Remove the slide and rinse with water. 4. Add counter stain seafaring for 1 minute then rinse again with water and blot dry with bibulous paper. MICROORGANISMS USED: * S. Erasures * S. Erasures B. Rues mix RESULTS/DATA USED 1. B. Cereus- green spores, pink vegetative cells, endoscope located in center of cell 2. B. Cereus S. Erasures- green spores, pink vegetative cells, endoscope located in center of cell CONCLUSION: An endoscope is a special type of dormant cell that requires heat to uptake the primary stain. To make endoscopes readily noticeable, a spore stain can be used. In using a microscope, under oil immersion, you will be able to identify the color of the spores, color of the vegetative cells and be able to locate the endoscope in certain bacteria like S. Erasures and B. Cereus. Question 1: Why is heat necessary in spore staining? Answer: The heat dries the dye into the vegetative cell of the spore. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 85 Question 2: Explain the function of water in spore staining. Answer: The water removes the excess primary stain, while the spores remain green the water nines the vegetative cells that are now colorless. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 85 Question 3: Assume that during the performance of this exercise you made several errors in your spore- staining procedure. In each of the following cases, indicate how your microscopic observations WOUld differ from those observed when the slides were prepared correctly. Answer: a. ) You used acid-alcohol as the decontrolling agent. The alcohol would wash out all coloring from the bacteria. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 5 b. ) You used seafaring as the primary stain and malachite green as the countersink. Seafaring will absorb to vegetative cells and not endoscopes since you need heat for endoscopes to form and malachite green will not absorb without heat but it will to vegetative cells. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 85 c. ) You did not apply heat during the application of the primary stain. Without heat, the endoscopes will not form and it will not penetrate the spore to color the vegetative cell. Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 5 Question 4: Explain the medical significance of a capsule. Answer: The capsule protects bacteria against the normal phagocyte activities of the host cells. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 7 Question 5: Explain the function of copper sulfate in this procedure. Answer: It is used as a decontrolling agent rather than water, washes the purple primary stain out of the capsular material without removing the stain bound to the cell wall, the capsule absorbs the copper sulfate and will appear blue. Cappuccino Sherman, p. 88 LAB EXPERIMENT NUMBER AAA The purpose of this experiment is to identify the best chemotherapeutic agents used for infe ctious diseases. S. Erasures is the infectious disease used for this experiment. MATERIALS: * Sense-disc dispensers or forceps * sterile cotton swabs * glassware marking pencil * millimeter ruler Using the Kirby-Bauer antibiotic sensitivity test method is used. This method Uses an Antibiotic Sense-disc dispenser, which placed six different types of antibiotics on an Mueller-Hint agar plate, infected with S. Erasures. The antibiotics are in the form of small, round disc, approximately mm in diameter. The antibiotics are placed evenly away from each other on the S. Erasures infected Mueller-Hint agar plate and incubated at 37 degrees Celsius for up to 48 hours. After the completed incubation time, any area surrounding the antibiotic disc which shows a clearing or an area of inhibition is then measured. Measurements are taken from the diameter of each antibiotic area of inhibition. This measurement will determine which of the antibiotics is best to be used against the specific organism. (In this case, S. Erasures) MICROORGANISMS USED: S. Erasures ANTIBIOTICS USED: Autocratic Erythrocyte Cylindrical Geocentric Fancying Linemen A chart showing the measurements of each antibiotic is used to determine its effectiveness. The three different types of ranges are: Resistant (Least useful) Intermediate (Medium useful) Susceptible (Most useful) The following results are: Zone Size Autocratic mm (Susceptible) Erythrocyte mm (Intermediate) Cylindrical mm (Intermediate) Geocentric mm (Susceptible) Fancying 13 mm (Susceptible) Linemen 21 mm (Susceptible) CONCLUSION: 4 of the 6 antibiotics above can be effectively used against inhibiting this organism (S. Erasures). This information would be passed on to the provider of the infected patient, so the patient can be given the antibiotic chosen by their provider and recover from this infection. LAB EXPERIMENT NUMBER BOB The purpose of this experiment is to evaluate the effectiveness of antiseptic agents against selected test organisms. MATERIALS: The materials used are five Traipses soy agar plates. 24-48 hours Triplicate soy broth cultures of E. Coli, B. Cereus, S. Erasures and M. Specialist. The microorganisms used were E. Coli, B. Cereus, S. Erasures and M. Specialist. The data collected in this experiment shows chlorine bleach having the broadest anger of microbial activity because it has the strongest ingredients. Tincture of iodine and hydrogen peroxide seems to have the narrowest range because the contents arent as strong. CONCLUSION: The Agar Plate-Sensitivity Method shows the effectiveness of antiseptic agents against selected test organisms. The antiseptic exhibited microbial activity against each microorganism. Question 1: Evaluate the effectiveness of a disinfectant with a phenol coefficient of 40. Answer: A disinfectant with a phenol coefficient of 40 indicates the chemical agent being more effective than the phenol. Source: Microbiology A Laboratory Manual 4th Edition/ James G.

jefferson and hamilton essays

jefferson and hamilton essays Both Thomas Jefferson and Alexander Hamilton are very popular known men today. Thomas Jefferson was born in 1743 in Virginia. Both had many different ways of looking at the world. Both were very different in many ways. Hamilton was a country person, while Jefferson likes to be a city person. At that time 95% of the people lived in the country, while only 5% of the people lived in the city. Thomas Jefferson was from the south. At that time there were two sides the North and the south. In the North the main image was that you were very religious. Though, in the south the main image was to fool around, basically to have fun. Jefferson could have been recognized as a country boy. Jeffersons idea for a government was that a farmer couldnt do what a local government could do, and a local government couldnt do what a state could have done, and a state couldnt do what a Federal Government couldnt do. Jeffersons beliefs included that aristocracy was a talent, while Hamilton thought that Hamilton thought aristocracy was a form of wealth. Jefferson could be known as a scientist, author, statesman, architect, philosopher, and a farmer. Jefferson wrote the Declaration of Independence, and came to know what is now America. Thomas Jefferson had many ups and down of his life. He became a president and served for two terms. Thomas Jefferson was the third president of the United States. After Jeffersons wife died in 1782 Jefferson became very lonely and sad. To overcome his loneliness Jefferson became a good friend with a married woman. They both liked the company of each other. No one knew if the friendship of the two was just more then friends. The year Jefferson was inaugurated it was 1801. Though, there was a secret relationship between Jefferson and his black housekeeper Sally Hemmings. He had several children from her as well. Jefferson never agreed too much of this but disagreed with it. Jefferson is th...

Hormonal Influences on Breast Tissue during the Normal Menstrual Cycle Assignment

Hormonal Influences on Breast Tissue during the Normal Menstrual Cycle - Assignment Example This paper illustrates that according to Suri, the hormonal imbalance in female patient affects MRI accuracy. Menstrual occurs during cycles of between twenty-three and thirty-five days. In the book, Suri, explains that after the first half of the menstrual cycle is the best time to perform a breast MRI in women who experience a normal menstrual cycle. It is very difficult to figure out the best time to perform an MRI on women with an irregular menstrual cycle. Studies have shown that it is essential for doctors to measure progesterone levels before performing a breast MRI in women with irregular menstrual cycles. This helps in improving accuracy hence reducing the possibility of repeat tests. An MRI uses magnetic and radio waves to create a three-dimension image of the breast. A gadolinium which is a contrast resolution is injected into the body during an MRI. It collects in areas which have cancer growth thus helping doctors to see cancer. When progesterone levels are high more blo od flows in the breast. When this is the case, the contrast solution collects through ought the entire breast. This makes distinguishing regular tissues and irregular tissues hard, hence a possibility of repetition. According to Michell, today measuring of progesterone level should be done before a breast MRI is done routinely especially for women who have irregular menstrual cycles. However menstrual cycle whether regular or irregular should be put into consideration before an MRI is done. Disappointingly, most radiologists do not assess progesterone level or even put the women’s menstrual cycle into consideration. This turns out to be very expensive due to the repeat test which cost a tone of money. If a woman is about to have a breast MRI scan, she should talk to her radiologist about timing the MRI with respect to their menstrual cycle. If possible, Michell suggests that women should avoid going for a breast MRI during the second half of their menstrual cycle. This is bec ause progesterone levels are high during this period hence affecting the accuracy of the MRI resulting to repeat tests which are very expensive.

Annotated bibliography - Essay Example The Truth and reconciliation process offers restorative form of justice that seeks to repair and solidify relationships between conflicting parties, victims and the general society. Restorative justice differs from retributive justice as it does not recognize punishment for those found guilty of facilitating conflict. The purpose of TRC in championing truth and reconciliation process is to determine and unveil truth to the public regarding the issues behind a particular conflict. Truth and reconciliation process therefore seeks to facilitate acknowledgement about a certain conflict, public mourning, healing and forgiveness among the people. In light of the above, Derek Rasmussen’s recommendation of reconciliation to forgive remains the only viable and practical way to achieve restorative justice, which is the basis of truth and reconciliation process. This is a news article written by the Canadian Broadcasting Corporation in reflection of the factors that led to the creation of the Canadian Truth and Reconciliation Commission. The article also identifies and recognizes commissioners appointed to serve in the TRC. According to the article, the move by the Canadian government through court to establish TRC related to the need to reconcile and console aboriginal Canadians who suffered in the Indian Residence School. The mandates of the TRC as indicted in the article were to investigate the reasons that led to the creation of the IRS system of learning and its impacts on the children. The article also reveals series of resignation by chairs of the committee as one of the challenges TRC of Canada faced. This article defines a very important material in facilitating the study bearing the clear information it depicts. Its importance to this study also relates to succinct definition and description of truth and reconciliation process as well differentiating restorative from retributive forms of justice.

Committing suicide Essay Example for Free

Committing suicide Essay By the end Sybil denies all to do with Eva committing suicide. The audience has never liked her and this makes things worse.  Mrs Birling is selfish, ignorant and up tight, just like Mr Birling. He starts the same way as his wife when the inspector shows up. Mr Birling is the man of the house and is involved in most of the play. He describes himself as a hard-headed man of business and tells Eric that he should look after himself and his family, he wants Eric to be a hard-headed man of business so he can take over eventually. He likes Gerald and would prefer him as a son rather than Eric because they both think the same way. When Sheila calls off the engagement Gerald understands but Mr Birlings plans are in ruins. He had planned co-operation between Crofts limited and his own company. I dont understand why you should come here, Inspector.  Arthur doesnt like the Inspectors attitude and makes this clear. He is probably the most disliked character in this play. What he did to Eva was considered a very minor thing but she was only asking for a small raise. He dismisses what Sheila and Sybil did. At the end he too looks for ways out. Mr Birling predicts the future occasionally and every time he is wrong. We can look back on what has already happened and we know that he is wrong. The Germans dont want war. Nobody wants war  - the Titanic-she sails next week-forty six thousand eight hundred tons- forty six thousand eight hundred tons- New York in five days-and every luxury-and unsinkable  In both cases he is wrong and the next case he will probably be wrong:  theres a very good chance of a knighthood-so long as we behave ourselves  This leads to scandal, which there is a lot of in this play. This also attracts the audiences as people enjoy things to gossip about especially when there are respectable or rich people involved. Geralds affair, Eric making Eva pregnant and Alderman Meggartys nasty private life. But she became your mistress.  Yes.  And you made love again?  Yes.  Hes notorious womaniser. About Alderman Meggarty.  Mr Birling was never liked and through the course of the play the audience likes him less and less.  I personally never thought about liking or not liking the Inspector, he is just there, putting the questions to the Birlings. He is the most assertive on the scene and the stage directions show he makes his presence felt even though Mr Birling repeats his past achievements. By the time Gerald returns from his walk he is too late to confront Mr Goole, his timing is perfect. Then Gerald tells us:  That man wasnt a police officer.  There is an element of shock and surprise but some of the audience may have guessed this. Who is he then?  That is one of many questions left open and unanswered. Most of them are about the Inspector. His name suggests something supernatural. Goole sounds like Ghoul this means, a person unnaturally interested in death. This is exactly what the Inspector is but it seems he can change the future. But just remember this. One Eva Smith is gone-but here are millions and millions and millions Eva Smiths and John Smiths still left with us, with their lives, their hopes and fears, with their suffering and their chance of happiness, all intertwined with our lives, and what we say and do. We dont live alone. We are members of the body. We are responsible for each other. And I tell you that the time will soon come when, if men will soon learn, then they will be taught it in fire and blood and anguish. Good night. The end is about the wars so he knows about the future and ends up changing it. He knows too much to be human. He already knows what has happened and is just there to make the truth come out and teach the Birlings a lesson, or else. As mentioned before he seems to be able to change the future because of what happens at the end.  The end of the play is not really the end, it is the middle because things are just getting interesting again. The biggest unanswered question is what will happen now, J.B Priestly has left this to us to think about and try to finish. The ending leaves everything wide open and open to debate and argument. It is the talking point of the whole play.  Yes? Mr Birling speaking What? -here-  That was the police. A girl has just died- on her way to the Infirmary- after swallowing some disinfectant. And a police inspector is on his way here- to ask some- questions-

Analysis of Robert Frosts Stopping by Woods on a Snowy Evening Essay e

Analysis of Robert Frost's "Stopping by Woods on a Snowy Evening" "Stopping by Woods on a Snowy Evening" is a very well know poem by Robert Frost. The poem appears to be very simple, but it has a hidden meaning to it. The simple words and rhyme scheme of the poem gives it an easy flow, which adds to the calmness of the poem. The rhyme scheme (aaba, bbcb, ccdc, dddd) and the rhythm (iambic tetrameter) give the poem a solid structure. The poem is about the speaker’s experience of stopping by the dark woods in the winter evening with his horse and admiring the beauty of the fresh fallen snow in the forest. Then, the speaker projects himself into the mind of his horse, speculating about his horse’s practical concerns and the horse communicates by shaking his harness bells, and his head impatiently wanting to continue the homeward journey forward. The speaker also tells that he would like to stay but he has to continue home to take care of all the responsibilities before he can die peaceful. In the first stanza, I think that the speaker is familiar with the land; he knows the individual who â€Å"owns† the woods; but that owner doesn’t live on this land instead he lives in the village. The speaker implies that he is trespassing someone’s property but he doesn’t need to worry because that person is in the village and not there anywhere around. So, it’s not an ethical problem for him. He is not ashamed of trespassing somebody’s property. Instead, taking advantage of the moment, h...

Questionnaire on fashion brands Essay

Factors Affecting Consumer Preference of International Brands over Local Brands Zeenat Ismail1âˆâ€", Sarah Masood2 and Zainab Mehmood Tawab2 1 Department of Social Sciences, Institute of Business Administration – Karachi 2 Students of Institute of Business Administration – Karachi Abstract: This study was conducted in order to determine the consumer preferences of global brands instead of local ones. It is also designed to find out the buying behavior patterns of young Pakistani consumers Consumer evaluates products based on information cues, which are intrinsic and extrinsic. A number of factors affect the consumer purchase decisions. The results suggest that most important factors that influence a consumer’s final decision are the price and quality of the product in question. Since the consumers usually associate the price of the brand with its quality, a brand priced too low is generally perceived as a low quality product. Similarly, a product priced too high may not be affordable by many. Other factors that have an impact on the consumer preferences are: consumer ethnocentrism, country of origin, social status, price relativity with the competing brands and family and friends. The research was conducted in Karachi and the samples selected included 200 people of age 16-24. The data collected for the research was through a questionnaire and was conducted in two popular shopping malls of the city and two universities since the target audience was largely the youth. Calculations were then analyzed and interpreted using a percentage of respondents and through frequency distribution tables and charts. Keywords: Consumer preference, International brands, Local brands 1. Introduction Globalization is an inevitable phenomenon that is leading the entire world towards becoming one market, a global village. Not only has the process of globalization aided immensely in the exchange of goods and services, information and knowledge through the reductions in international barriers, but it has also led the world into becoming a real single universal community comprising of people from different cultures, thus resulting in the shrinkage of the world. With the world becoming a single market, globalization has had a major contribution in enabling the organizations worldwide to step out of the restricted domestic markets and to set up their operations across the globe with confidence. This has largely led to a decline in the importance in national borders and a greater emphasis on what the consumers actually demand; be the consumers located in the very country in which the organization exists or an entirely different part of the world. Moreover, with the rapid increase in global competition, companies that strictly adhere to and cater to the needs of the local markets are finding themselves at a disadvantage and gradually loosing the competitive advantage that they so much strived to achieve. However, for some products and services â€Å"the tastes and preferences of consumers in different nations are beginning to converge on some global norm† (Holt 2002). From a consumer perspective, however, reactions to the prevalence of global brands seem to vary among the different customers. On the one hand, consumers seem to value and admire global brands and regard such brands as a status symbol. On the other hand, global brands are often criticized for threatening the local differences and imposing the western cultures on our society, leading to a loss of cultural identity. 2. Purpose of the study: âˆâ€" Email: zismail@iba.edu.pk Tel #:+92(333) 3775545 Fax #:+92(21) 38103008 54 This study is aimed at determining consumer preference of the youth of international brands instead of national or local brands in Pakistan. There are various factors which influence consumer purchase decision. Such as  Country of origin, price of the brand fashion, family and friends, brand name, availability, advertising campaigns, consumers’ ethnocentrism etc. The study is also designed to find out the buying behaviour patterns of the young Pakistani consumers, attitudes towards global and local brands and the preference for foreign brands. 3. Literature review Brands have been constantly reviewed and redefined in the marketing literature and there are numerous definitions for ‘brand’. A definition of a brand by The American Marketing Association (AMA) in the 1960s (Keller, 1998:2) is â€Å"a name, term, sign, symbol, or design, or a combination of them, intended to identify the goods and services of one seller or group of sellers and differentiate them from those of competitors.† For consumers, when deciding between brands which are in the marketplace will include brands as an element to determine the qualities of the product rather than employing their time to enhance their knowledge of the product in information searching activities. Therefore, consumers use brands as cues to make decisions to purchase or try products (Ger et al., 1993). 4. Quality Perceived quality is defined as the consumers’ judgment about an entity’s (service’s) overall excellence or superiority (Zeithaml, 1988 and Rowley, 1998). Research also indicates that consumers value global brands especially for their assumed high quality and prestigious image (e.g., Nguyen, Barrett and Miller 2005; Steenkamp, Batra and Alden 2003). An internationally well-established brand name can act as a â€Å"halo† constructs that effects quality beliefs (Han 1989). If a brand is perceived as globally available, consumers are likely to attribute a superior quality to the brand, since such quality is thought of as a prerequisite for international acceptance. 5. Country of origin The country of origin effect has been defined as â€Å"the positive and negative influence that a product’s country of manufacture may have on consumers’ decision making processes or subsequent behavior (Elliott and Cameron, 1994). 1991). Infact in the words of Nagashima (1970), COE can be defined as  Ã¢â‚¬Å"the picture, the reputation, and the stereotype that businessmen and consumers attach to products or brands of a specific country. This image is created by such variables as representative products, national characteristics, economic and political background, history, and traditions†. The literature on country-of-origin effects is quite rich and covers the topic from different perspectives in different countries. Some studies have shown that country of origin also has symbolic and emotional meaning to consumes, and it plays an important role along with other attributes such as quality and reliability in shaping consumers attitudes toward products. Moreover, attitudes and perceptions of consumers toward brands and products will depend on categories, for instance, electronic goods from Italy may be perceived as a poor quality but Italian clothing would be perceive as fashionable and high quality (Bikey and Nes, 1982). This would be differently perceived with Japanese brands as Japanese electronic goods would be perceive with positive attitudes and Japanese clothing will be negatively perceived. 6. Price Researchers found out that once consumers perceive a price difference between local-owned and foreignowned brands, price dissimilarities begin to affect their preference for local-owned brands. Therefore, since price is also one of the most important extrinsic cues that consumers use when evaluating the product/brand (Hansen, 2005), we test the impact of price against consumer’s ethnocentric tendencies to determine at what point consumers are willing to forsake preference for local products for a greater price discount with foreignowned products. 7. Social status 55 Authors have stressed that consumers may prefer global brands because of associations of higher prestige (Schuiling & Kapferer, 2004; Shocker, Srivastava, & Rueckert, 1994; Steenkamp, et. al., 2003). Global brands may have a higher prestige than local brands due to their relative scarcity and higher price. Furthermore, global brands may also stand for cosmopolitanism. Some consumers prefer global brands because they enhance their selfimage as being cosmopolitan, sophisticated, and modern. Conversely, according to Ger (1999), local brands tend to be targeted and positioned based on a deep cultural understanding and therefore create â€Å"a sustainable unique value and offer the symbolism of authenticity and prestige†. Still, consumers have been found to have no intrinsic preference for global brands (De Mooij, 1998). 8. Friends and family Reference groups include groups or people whom one can look up for guidance and ask for opinion. These are important source of influencing the brand purchases. Reference group include friends and family who influence ones buying decisions due to special skills, knowledge, personality. If a friend had a bad experience with a product, it is more likely that one will refrain from buying it. However many studies found out that, knowledge that consumers obtain through direct personal experience will be perceived to be more trustworthy than information from other communications. This results in more strongly held beliefs (Swaminathan et al., 2001). 9. Research Questions The reasons for consumer preference of global brands over the local ones. The product attributes that are mostly considered by consumers when buying a brand. The demographic characteristic of consumers who buy foreign brands more frequently. 10. Research methodology This study is a descriptive study and more of a qualitative nature and was conducted to identify and analyze the reasons why consumers prefer international brands to national brands when purchasing consumer goods. The sample for this research included the 200 consumers whose ages ranged from 16-24 years from Karachi. Simple random sampling was used for this study. Questionnaires were used to collect primary data. The questionnaire included closed ended questions and Likert scale is used in most of the questions. These questionnaires were distributed to collect data from the students of  Institute of Business Administration itself as well as the students of Institute of Business Management. Apart from this, we also visited Park Towers shopping mall and The Forum, the two leading shopping malls in Karachi, with the aim of collecting data for our research from the shoppers there. 50 questionnaires were distributed to each of the universities and shopping malls in equal proportion to males and females. We mainly classified our population according to gender. Frequency distribution and bar charts have been used to evaluate the results. In addition to this, the means of different factors that influence consumers’ preferences of the local and global brands were used to determine which factors are considered the most by consumers when purchasing different brands. 11. Findings and Discussion 11.1. Question 1: Do you use international brands products? 56 According to the data collected, 72.5% of the people used international brands of which 60 were male and 85 were females. 18.5% of the people questioned claimed to use international brands occasionally, whereas, 9.1% of the people claimed not to use global brands at all. As indicated in the pie charts above,18.5% of the people who used the global brands sometimes included 28 males and 9 females, and those who did not use the global brands consisted of 12 males and 6 females. 11.2. Question 2 If an international brand and a national brand are priced same, would you prefer the international brand? The purpose of this question was to evaluate and discover how important a factor such as price is in determining whether the consumers would go for the domestic brand or stick to the global one if both the products were in  the same price range. The results found out that 76% of the consumers would go for the international brands whereas 24% would still purchase the domestic ones. 11.3. Question 3 Do you consider where a product is manufactured when purchasing it? F r e q u e n c y d i s Responses This question was asked to discover how much importance the youth lay on the country of origin as a factor when making a purchase. The results revealed far different results compared to what had been stated by the review of previous researches done. As indicated in the graph, the youth was found to be mailnly ignorant of the country in which the brand was manufactured. Majority of the consumers (76% males and 88% females) did not consider it as significant a factor as to affect his or her purchase decision. 11.4. Question 4 It is said that people buy international products so that they can be accepted in a particular social group. Do you agree? 57 The results to these two questions confirmed the general perception that exists in our society, that is, the global are purchased as a status symbol. The youth mainly bought foreign branded products to be able to fit in a particular social group. This occurs largely because peer pressure tends to be high at this age, and most of the people find themselves being victims of inferiority complexes. The results to the first of these questions indicated that on average 75% of the youth (71 males and 79 females) purchased the international and local brands as a status symbol. These results were further enhanced by the results to the next question, which showed that 72% of the males and 68% of the females did, infact, believe that the people purchased the international brands to be able to fit in a particular social group. The table above compares the means of the different factors in influencing consumer preferences of the global brands over the local ones. The means, expressed in percentages, indicates that amongst all the factors, the quality of the branded product was considered the most important factor in shaping the consumers’ purchase decision. The current trends and fashion were found to be just as important, but the price of the product was not found to be more important than the prevailing fashion and styles. The reason why 85% of the people decide to buy a particular brand was mainly because it was reflective of the ongoing fashion and there were only 5% people on average, who did not give importance to the ongoing fashion when purchasing a product. The results revealed that price was rated as the third most important factor in influencing consumer choice, whereas the quality of the product was considered the most significant, followed by the current trends and fashion. Mean number of people ( in percentages) Yes Sometimes 76% 16.5% Price of the product 4.5% 13.5% Country of origin 87.5% 7.5% Quality of the product 75% 15.5% Status symbol 85% 10% Current fashion and trends 64.5% 17.55% Family and friends 60% 20.5% Ethnocentrism No 7.5% 82% 5% 9.5% 5% 18% 19.5% Country of origin, as a factor in influencing consumers’ choice of the brand was hardly a significant factor, since 82% of the people, on, average claimed that they did not consider which country a product is manufactured in when making purchase decisions. Only 4.5% people, on average, claimed that they do consider the country of origin when purchasing a brand. The ethnocentrism factor was considered by 60% of the people questioned. This indicates that most of the people believed that as a Pakistani we should buy our local brands rather than giving preference to the global brands, however, this was what they believed to be the ideal scenario. In practice, our people, especially the females were found to be extremely prone to the global brands. According to our findings, 78% of the females were not willing to even substitute the global brand with a domestic if the foreign  brand is not available. The males, however, were not found to be that prone to the foreign brand. The results also show that status symbol is also perceived to be a major factor in shaping consumer purchase decisions. The above table reveals that 75% of the people linked the branded product with their social status when actually purchasing it. The table provides a summary and ratings of the factors influencing consumer preferences of the national or international brand. 12.
