Defining Racism In America

Defining Racism In America Race and race relations have been aspects of American society since the colonial era. With the exception of a handful of countries, no other nation has dealt with the struggles of a multiracial society and has had to overcome the problems created in its nations past. As a result, race in America is a complex issue with many facets and race relations have become increasingly difficult to define. Richard Thompson Ford, in examining the current race situation in America in his book The Race Card, defines the period as post-racism. Focusing on Fords ideas, as presented in his book, as well as an investigation into the Jena Six story, which is a contemporary example of racism, a more defined picture of current race relations in America can be uncovered. Fords The Race Card provides a critique on the current race situation in America. In his book, while Ford presents the idea that America is post-racism, he asserts that post-racism is not defined in the traditional way one might assume. To Ford, post-racism is a late stage of racism in which its contradictions and excesses both cancel out and amplify its original function (2008:25). To Ford, the era of post-racism allows people to have internal feelings of racism, as long as their overt actions and behaviors are not racist. Racial stereotypes may still exist, but no longer are those stereotypes defined by White Only establishments. With the elimination of the stereotypical racism, racism may now be harder to eliminate because overt racists will remain unidentified. Prior to the Civil Rights Movement, segregation laws and blatant bigotry provided easy markers to define racism and identify racists. Today there are laws preventing outward expressions of racism, making the process of defining the current state of race relations far more difficult. According to Charles Hirschman, racism is the belief that people can be divided into categories based on certain features that define a particular look (2004). While characteristics that define a person as part of a particular race are biological, race is a socially constructed concept in which people place meaning on the biological features. The seeds of racism in America were planted out of the need for a cheap and renewable labor force. When indentured servitude was no longer profitable to this countrys landowners, it prompted a needed change. Dark-skinned Africans, brought to this country as slaves, looked different from the white land owners. Based on that difference of appearance, along with the historical lack of a formal schooling, American society regarded them as inferior. This view by society eventually lead to the social construct of race, with whites seen as superior and blacks as inferior. While slavery was abolished following the Civil War, the overt concept of racial inferiority continued until the Civil Rights movement in the 1960s (Pinkney 1999). Up until the Civil Rights Act was passed, Jim Crow laws and other discrimination laws continued to segregate the races and reinforced the societal view of the inferiority of African Americans. Following the passage of the Civil Rights legislation, overt racism no longer was socially acceptable. Racism is no longer is defined by superiority and inferiority, but rather is defined as an acknowledged difference between cultures, with one no better than the other (Miles and Brown 2003). Because of the years of segregation, there are inherent differences between the black and white cultures. While segregation and discrimination no longer are a common practice, there still are differences between the groups and implicit discrimination remains. The faces of racism have changed, but racism has yet to disappear from society. Today, those who are identified as racists, under the old definition, are labeled as bigots and outsiders by society. Although there still are those who are viewed as racists under the traditional definition, there is a new form of racism present and it is much harder to define. As defined by Ford, the current state of racial affairs revolves around playing the race card. In playing the race card, people must presume that discrimination remains and it is based on ones race. More often than not, todays discrimination is a based on the many years of inferior treatment. In other words, people today claim racism because, at one point in history, it could be considered a result of racism (2008:31). There are four instances of playing the race card that are outlined in Fords book, including racism without racists, racism-by-analogy, unclear definitions of what is racism, and unclear goals for the current movement. People use the racism without racists definition because it is the easiest conclusion to use when explaining the motivations of others. There may be extenuating circumstances as to why people act a certain way, but people cry racism because it is an easy answer; they fail to see the situation from the other persons point of view. In racism-by-analogy, other groups claim that their struggles and discrimination are equal to those fought for in the Civil Rights Movement, even though they are not the same. As an example, people that are overweight or not pretty enough may make the claim that their legal rights are being violated, even though overweight is not a protected class under the legislation. Having unclear definitions of racism causes people to overuse the claim. There are many factors that motivate peoples actions, and it is not always based on race. With no clear-cut definition of present-day racism, the resulting lines are blurred as to what actually constitutes racism in todays society. Without an accepted definition of racism and no clear goals for the improvement of race relations, it is difficult to determine when playing the race card may be beneficial or detrimental to a movement. This unknown result causes internal conflict within the movement itself, preventing it from moving forward. Overall, Fords argument is correct in its assertions. The face of racism today has changed and a new era of race relations has begun. No longer are there overt forms of racism and discrimination, but rather there are more subtle situations affecting race relations in todays society. However, Fords argument is not as simple as post-racism and the race card; there still are societal and structural boundaries and obstacles that African Americans cannot seem to overcome. While legally discrimination and segregation are no longer present, there are still examples of it today. As author Shawn Utsey, et al., argues, there are three forms of racism that still exist today: individual, institutional and cultural racism (2000). Examples of individual racism include racial profiling and the lingering sentiments of the overt racism seen during the Civil Rights Movement. Residential segregation and other societal restrictions constitute institutional racism. Cultural racism refers to the lack of African American influence in mainstream American culture and history. These new forms of discrimination and segregation define the current race relations in contemporary American culture. A contemporary example to which Fords ideas of post-racism and the race card can be applied is the Jena Six incident. There are many incidents which occurred in Jenna, Louisiana, between September to December 2006, which contributed to the belief that racism and discrimination were involved in the Jena events (Newman 2007). The first incident occurred in September, involving nooses hung from a tree at the local high school. As is common at most high schools, certain social groups congregate in specific areas, though not necessarily based on race. At Jena High School, a racially diverse school, a specific tree commonly was known as the white tree. A black freshman asked the principal if he could sit under the tree and the principal assured him that he could sit wherever he wanted. The next day, two nooses were hung from the tree, though the motivations behind the hanging of the nooses were unclear. The students responsible for hanging the nooses were identified and suspended. When the suspensions were announced, the black community of Jena was enraged, insisting that the nooses were a symbol of a threat against the black students of the high school. There were two altercations between white and black students, which some claimed were a result of the events that occurred in September. At a party, five black students attempted to enter a party, but were denied entrance because they did not receive an invitation. An altercation ensued, resulting in a white student being charged with battery. The next day, another altercation occurred outside a convenience store between a white male and three black males, one of which had been involved in the previous altercation at the party the night before. One of the black students was charged with disturbing the peace, second degree robbery and the theft of a firearm. The final event, which ultimately is what led to the national publicity, was an altercation between six black students and one white student, Justin Barker. Barker was badly beaten, but was released from the hospital after three hours in the emergency room. Five of the six black students were charged with attempted second-degree murder, though the charges later were reduced to battery. Mychal Bell originally was charged with aggravated second-degree battery and tried as an adult, but his conviction later was overturned. The five who originally were charged later were convicted of simple battery (Associated Press 2007). Due to the events leading up to the attack on Justin Barker, many consider this to be a result of racial tensions in the town. This was reinforced by the filing of the charge of attempted murder to the Jena Six at the beginning of the trail proceedings, a charge many considered to be racially driven and not fitting to the crime. Many also believe that the all-white jury, which delivered the original guilty verdict against Bell, levied an unfair sentence. While on the surface these events seem to be motivated by racism, the events involving the Jena Six are more of a case of Fords racism without racists. Because the events which occurred in Jena involved both whites and blacks, people assume racism was a determining factor. However, most of the events leading up to the Barker incident were unrelated. Even when considered separately, racism is not the only motivation for the actions which occurred. The tree that was claimed as the white tree by the student body has since been refuted by the faculty and staff at Jena High School. According to later testimonies, students of all races sat under the tree at one point or another. There also was a conflict over the number of nooses which were hung from the tree on the following day, and further investigations revealed that only two were hung, not three, which is believed to be a symbol of the Ku Klux Klan. The nooses, it later was found, were a prank aimed at the rodeo team, not hung as racist symbols. As it later was learned, school administrators cut down the nooses before classes started because students were playing with them in inappropriate manners, not because of some underlying racial context. Following the Jena incident, the United States Justice Department conducted an investigation to determine if the act was in fact a racially-motivated hate crime. It was determined that the hanging of the nooses was an isolated event without lasting racial tensions at the school. As such, there is no direct connection between the events occurring in September and the Barker attack. Each event was separate and unique, yet collectively were made to seem as a cause and effect relationship by the media. Finally, the allegations accusing the all-white jury of delivering a racially-motivated verdict fails to take into account underlying causes. Due to the makeup of the town, there are only a small number of African Americans to select for jury duty. Of those summoned for jury duty, some were African American but failed to report on the day of the trial (Mangu-Ward 2007). The events that occurred in Jena led to one of the largest race riots in recent history. Sensationalized by the medias influence, the case seemed to be a series of events indicating the continued racial tensions of the South. When looking deeper into the facts, a different picture is seen. Instead, each event is isolated and unconnected. The coincidences surrounding the events seem to point to a plot against African Americans, yet the motivations had no racial underpinnings. Throughout American history, racism has played a major role in race relations. Although overt racism has become a lesser focus, examples of racial discrimination and segregation still exist in todays society. The era of post-racism has a new set of issues effecting society and the race relations within it. Until these issues are resolved, true racial equality cannot be attained.

ZigBee Physical IEEE

ZigBee Physical IEEE This report work started with extensive literature study in several area of ZigBee, particular in the physical aspect. This knowledge was then implemented in simulating the physical aspect of the Zigbee working in the range of 2.4 GHz. Various parameter of the physical layer are alter to demonstrate the its effect by using MATLAB(syntax code in M-file and Simulink). Results are analyzed and compared to demonstrate how the actual standard and specification are derived. 2.0 Literature Review Zigbee is known as IEEE 802.15.4 Low-Rate Wireless Personal Area Network (WPAN) standard is part of the IEEE 802 family of digital communication standards. It is designed for low-cost, low-power applications that require relatively low data throughput which is down to an average of less than 1 bps. It is also differentiated from IEEE 802.15.1TM (Bluetooth TM) in several respects; it does not support isochronous voice, as Bluetooth does. Figure 2.0(a) shows the comparison with standard and technologies. 2.1 Applications ZigBee technology is well suited to a wide range of energy management and efficiency, building automation, industrial, medical, home automation applications. Essentially, applications that require interoperability and/or the RF performance characteristics of the IEEE 802.15.4 standard would benefit from a ZigBee solution. Examples include: Demand Response Advanced Metering Infrastructure Automatic Meter Reading Lighting controls HVAC control Heating control Environmental controls Wireless smoke and CO detectors Home security Blind, drapery and shade controls Medical sensing and monitoring Universal Remote Control to a Set-Top Box which includes Home Control Industrial and building automation 2.2 Advantages The most appealing advantages Zigbee has is low power consumption due low duty cycle of end device that only turns on when required, uses only small capacity of battery but long operating time. It is also relatively low cost compare to other wireless network. It offered low message throughput with the size of code ranges from 32kB to 70kB and is only approximately 10% of code size used in Bluetooth technology. Other advantages are listed below: -Large network order. -Few QoS guarantee -Selectable levels of security based on the Advanced Encryption Standard with 128-bit keys (AES-128) s. 2.3 Physical layer IEEE 802.15.4/ZigBee has two available physical layers. In the 2.4-GHz band, it supports a data rate of 250 kbps; there are 16 available channels, centred at 2405 + 5k MHz, where 0 ≠¤ k ≠¤ 15. The other physical layer is a regional one, covering the 868.0 to 868.6 MHz band available in Europe and the 902 to 928 MHz band available in much of the Americas. There is a single channel in the 868 MHz band, centred at 868.3 MHz, with a BPSK data rate of 20 kbps; the standard supports a BPSK data rate of 40 kbps in the 902 to 928 MHz band, with channels centred at 906 + 2k MHz, where 0 ≠¤ k ≠¤ 9.[1] 2.4 Network topologies To meet its wide range of potential applications, IEEE 802.15.4/ZigBee supports star, mesh, and tree networks, the latter two being multihop networks. Multihop Network: A multi-hop communications allows data from one device to be relayed to another device via intermediary devices. By relying on these intermediary devices, the range of a given network can be significantly increased while at the same time limiting the power consumption of each device. [2] Star Network: Star network topologies are commonly referred to as point-to-point and point-to-multipoint networks. This topology can be supported by either ZigBee or 802.15.4. In this network, all devices are limited to â€Å"single-hop† communications. Typical applications for star networks include garage door openers and remote controls. [2] 2.5 DSSS (Direct Sequence Spread Spectrum) IEEE 802.15.4 uses direct sequence spread spectrum (DSSS) for robust data communications. A DSSS spectrum system is spreading baseband by directly multiplying the baseband data with the PN code sequence. At the receiver side code, synchronization is received and the signal is passed through a filter. At the next step, it is multiplied by a local version of the same PN sequence. The received data are then dispread. The signal bandwidth is reduced. An interference signal will be spread when multiplying with the dispread sequence and the power of the interference is reduced when the bandwidth are increased. The part of the interference signal that does not have the same bandwidth as the desired signal is then filter out. In this way the most of the interference power is eliminated. 2.6 Channel Access There are two types of channel access in the IEEE 802.15.4 defined communication system. They are based on whether the devices want to retain their own exclusive time slot for communication or they have to compete with other devices for accessing the channel. The contention based allows the devices to access the channel in distributed way using CSMA CA algorithm. With this method each devices has to scan the air medium for free channel or to compete with other devices for the channel access. With contention free method, the network coordinator decides about the channel access by using Guaranteed Time Slot (GTS) of the channel space. This method is suitable for latency sensitive devices that require short delay time and no competition for channel access. To meet its low average power consumption goals, IEEE 802.15.4/ZigBee is capable of extremely low duty cycles — below 10 ppm [3]. The standard also supports beaconless operation — an asynchronous, asymmetrical mode supporting unslotted CSMA-CA channel access for star networks — that enables devices other than the receiving central node to remain asleep for indefinite periods, thus reducing their average power consumption still further. 2.7 Data processing IEEE 802.15.4 2.4-GHz physical layer uses a 16-ary quasi-orthogonal signalling technique — trading signal bandwidth to recover sensitivity with coding gain. A particular 32-chip, pseudo-random (PN) sequence is used to represent four bits [3].A chip is a symbol from p-n code sequence. There are 16 chips sequence and one is defined in table below: Information is placed on the signal by cyclically rotating or conjugating (inverting chips with odd indices) the PN sequence 8. The PN sequence is rotated in increments of four chips: symbols 0 through 7 represent rotation without conjugation; and symbols 8 through 15 represent the same rotations, but with conjugation. In this way, four bits are placed on each transmitted symbol and, because transmitted symbols are related by simple rotations and conjugations, receiver implementations can be simplified over other orthogonal signalling techniques that employ unrelated PN sequences. Half-sine shaped Offset-Quadrature Phase Shift Keying (O-QPSK) is employed, in which the chips of even index are placed on the I-channel and the chips of odd index are delayed one-half chip period and then placed on the Q-channel. The chip rate on either the I or the Q channel is 1 Mchip/s, so the overall chip rate is 2 Mchip/s. The symbol rate is 62.5 k symbols/s, leading to a data rate of 250 kbps. [4] 3.0 Description of the Simulator In this report, Simulink and syntax code (M-file) in MATLAB are used to generate the scatter plot. For the implementation of overall block system in Simulink model, the equivalent block diagram is as shown above. The Simulink model block consists of random integer generator, modulator and demodulator, noise channel and also error rate calculator. Simulink model effectively represent the complicated syntax code into system model block. The signal is generated by using a Random integer, the Random Integer Generator block generates uniformly distributed random integers in the range [0, M-1]. Then, the signal are modulated by OQPSK, the Offset Quadrature Phase Shift Keying (OQPSK) modulation scheme is used in this assignment. As stated in literature review, Offset Quadrature Phase Shift Keying (OQPSK) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. Addictive White Gaussian Noise is then added to the signal to simulate a practical channel w hich consists noise. After that, the signal is demodulated by using the same scheme-OQPSK. Result are compared with the initial signal (output from the Random Integer) to calculate the BER and SER performance of the scheme. The Discrete-Time Scatter Plot Scope block displays scatter plots of a modulated signal, which are located after AWGN block to reveal the modulation characteristics, such as channel distortions of the signal. For M-file code, the sequence is similar as the above block diagram, the following command are to used to generated the random signal : out = randint(m,n,rg) The code represented above generates an m by n integer matrix of random number. Variable â€Å"rg† represent the range of random number to be generated. The modulating part and demodulating are done by using the below code: y = oqpskmod(x) y = oqpskdemod(x) To add noise to the signal: y = awgn(x,snr,measured) Where x is the input signal and â€Å"snr† is the signal to noise ratio. The scatter plot are plotted by using: scatterplot(y) Besides plotting the scatter plot, the BER versus SNR curve are plotted as it is important to compare different modulating scheme in term of the BER performance. This is done by using syntax code in M-file. The complete code is attached in the appendix. The following is the flow chart to describe the sequence of the code. At the end, three graphs are generated ideal BER characteristic, practical BER characteristic and SER characteristic. 4.0 Result and Discussion . Dots are located at the centre of the boundary lines which is within the box or boundary line. This indicated that proper digital signal is being received. The closer the detected level/phase dots are plotted to the middle of the boundaries, the lesser noise and interference to the digital signal. However this diagram will never be obtain in practical cases. Therefore to simulate a practical real cases, Addictive White Gaussian noise must be considered, Additive Gaussian noise disturb the digitally modulated signal during analog transmission, for instance in the analog channel. Additive superimposed noise normally has a constant power density and a Gaussian amplitude distribution throughout the bandwidth of a channel. If no other error is present at the same time, the points representing the ideal signal status are expanded to form circular â€Å"clouds† as shown below. As figure above shown, scattering of the dots indicates some marginal signal performance degradation but not enough to cause significant digital bit errors because dots are still located inside the boundary. Only dots to the edges of the quadrant or beyond represent significant degradation that results in bit errors during decoding which are shown in figure below generated by using Simulink . In conventional QPSK, change in the input bit from 00 to 11 or 01 to 10 causes a corresponding 180 ° shift in the output phase therefore an advantage of OQPSK is the limited phase shift that must be imparted during modulation. The sudden phase-shifts occur about twice as often as for QPSK (since the signals no longer change together), but they are less severe. In other words, OQPSK has smaller jumps when compared to QPSK. This lowers the dynamical range of fluctuations in the signal which is desirable in engineering communications signals. As mentioned earlier, the simulation is performed to study the performance of the design model. The study is done by observing the bit error rate (BER) with respect to the signal to noise ratio (SNR) The simulation (Figure 4.0(f)) compares the BER versus SNR curve for different modulation scheme used. Four different modulation schemes is taken into comparison, which is the Quadrature Amplitude Modulation (QAM), Quadrature Phase Shift Keying (QPSK), Differential Phase Shift Keying (DPSK) and finally Offset Quadrature Phase Shift Keying (OQPSK) employed by Zigbee operating at 2.4GHz radio band. By comparing different modulation scheme give better insight on which modulation is better and suitable. All modulation schemes are simulated with the value M = 4, where it is effectively represented by n = 2 bits which can be calculated from the following formula below: n = log2 (M) The first graph below shows the theoretical bit error rate versus signal to noise ratio curve. For practical system, white Gaussian noise is added. If comparison is made between theoretical graph and practical graph, it shows that there is not much of the different in term of the shape of the graph. ,it shows that for all the modulating scheme, the higher the SNR the lower the BER (bit error rate).The same principal are apply to the symbol error rate(SER) vs SNR(figure 4.0(g)). For BER vs SNR, comparing the four different modulation schemes from the practical graph plotted, DPSK modulation scheme shows to have the worst bit error rate at any level of SNR, followed by QPSK and QAM having approximately similar bit error rate at any SNR level. The OQPSK tends to have the lowest bit error rate at any SNR level if compared to other modulation scheme, which is desired. The comparison is done by taking one fixed SNR level, for example, considering the SNR level of -2. The bit error rate of OQPSK falls approximately to 10-2, which is the smallest. The QAM and QPSK have bit error rate falls within the range of 110-1 to 510-1, slightly much higher than OQPSK. The DPSK has the highest bit error rate, which is above the range 110-1. 2dB Graph 4.0(h) illustrate symbol error rate (SER) versus signal to noise ratio (SNR) under the same condition for the four modulation scheme. The SER versus SNR curve has similar characteristic over the BER versus SNR curve, with OQPSK being in the best performance, followed by QPSK and QAM and DPSK having the worst performances. Low average power is achieved with a low overall system duty cycle. However, low duty cycle must be achieved with low peak power consumption during active periods because most of the target power sources have limited current sourcing capabilities and low terminal voltage, and it is not desired to implement with complex power conditioning systems for cost and efficiency reasons. At the physical layer, the need for low duty cycle yet low active power consumption implies the need for a high data rate (to finish active periods quickly and return to sleep), but a low symbol rate (because signal processing peak power consumption is more closely tied to the symbol rate than the data rate). Therefore, this implies the need for multilevel signalling (or m-ary signalling, with m > 2), in which multiple information bits are sent per transmitted symbol. However, simple multilevel signalling, such as 4-FSK, results in a loss of sensitivity. As can be seen from figure 4.0(h), OQPSK provides a 2-dB increasein sensitivity over nearest scheme (QAM). For modulating scheme with low sensitivity, there is a need to recover the needed link margin (i.e. range) without resorting to directive antennas, the transmitted power must be increased or the receiver noise figure must be reduced, both of which can increase power consumption significantly. 5.0 Conclusion In conclusion, IEEE 802.15.4 is still a new standard which has the potential to unify methods of data communication for sensors, actuators, appliances, asset tracking devices and so on. It offers the means to build a reliable and affordable network backbone that takes advantage of battery-powered devices communicating at low data rates. In addition the complexity and cost of the IEEE 802.15.4/Zigbee-compliant devices are intended to be low. It can potentially create a whole new ecosystem of interconnected home appliances, light and climate control systems, and security and sensor sub-networks. In this respect, the implementation of the physical layer of the IEEE 802.15.4 standard must be optimized to meet the challenging low-cost and low-power targets. From the context above, various test and evaluation on the BER versus SNR curve and scatter plot for various scheme are done on physical layer of the ZigBee, the result shows that OQPSK is the most suitable modulating scheme which fit the ZigBee (2.4 GHz band) characteristic (low power consumption, high sensitivity, high reliability and low cost ). Thus it coincides with the actual standard for Zigbee. 6.0 References 1. Sensor Technology Handbook, Page 593 Section:  22.

atomic bombing :: essays research papers

Nuclear war was brought about through the invention of the atomic bomb. The atomic bomb was first thought of in 1939. The Manhattan Project was devoted to researching and constructing the bomb (Serendipity: Manhattan Project para.1). Six years and 2 billion dollars later the Manhattan Project produced the first atomic bomb in history (Serendipity: Manhattan Project para.5). The bomb was tested in northern New Mexico on July 16th, 1945. The creators of the bomb watched the first detonation. One creator quoted from the Bhavad Gita saying, â€Å" I am become death, the destroyer of worlds.† The testing of the bomb in New Mexico was the first detonation, however it was not the last (Serendipity: Manhattan Project para.10). The atomic bomb was again set off in Hiroshima on August 4th, 1945. This time the bomb was used in warfare (Serendipity: Detonation para.1). Two aspects of these bombings were the injuries to the people caused by the bomb and the long-term effect the bombing ha d on the culture. There were three main kinds of injuries caused by the bombing: burns, mechanical, and radiation. The burns were due to the flash radiation of heat. The mechanical injuries were caused by debris in the air thrown by falling buildings, etc. the radiation injuries were from the gamma rays produced from the nuclear bomb itself (Avalon: Characteristics of Injuries para.1). Without exact numbers it is hard for experts to determine the actual death rate caused by each injury. Most would say that that majority of the deaths were caused by either radiation or mechanical injuries (Avalon: Characteristics of Injuries para.2). Two different kinds of burn were reported after the bomb, flame burn and flash burn (Avalon: Burns para.1). People that had any sort of protection or shielding around them were protected from flash burns (Avalon: Burns para.4). Japanese experts estimate that burns caused at least 50 percent of the deaths in Hiroshima. They say that most burn victims died instantly (Avalon: Burns para.5). The second form of injury due to the bomb was referred to as mechanical injuries. These injuries were cause by flying objects, falling buildings, crumbling walls, etc. People that were injured from these things experienced fractures, lacerations, concussions, abrasions, etc (Avalon: Burns para.1). The third and most talked about injury caused by the bombing were the radiation affects on the human body. Most people were expected to experience the affect of radiation seconds after the bombing.

The Death Penalty :: essays papers

The Death Penalty "An eye for an eye, a tooth for a tooth." This is another way for someone to say they are supportive of the death penalty. The death penalty, to me, is revenge. It kills innocent people every year. Many of the families of victims do not want the criminals to be put to death. The death penalty costs more than a life sentence in jail. It is also racists. "Since 1976, there have been five hundred twenty-three executions in the United States, twenty-three in 1999 alone. There was only eleven before 1984. Then the number rose to twenty-one that year. The number of execution stayed around twenty then dropped to eleven in 1988. Then it steadily rose from there to seventy-four executions in 1997. That was the highest since 1976."(Death Penalty Information Center, P.1) There are many different methods of execution used by the government. The most common is lethal injection used by thirty-four states. Electrocution is another method, which is used by ten states. The gas chamber is used in five states. There are still two states today that use hanging as a method of execution. And two other states use a firing squad. The death penalty is also extremely racist. There have been significantly more executions of minorities than white Americans. Capital punishment also goes against the Constitution of the United States. Amendments eight and fourteen state that no cruel and unusual punishment can be inflicted, and no state can deprive any person of life liberty or property. The death penalty clearly takes these privileges away from American citizens. "More than 2000 people are on death row today. Virtually all are poor, a significant number are mentally retarded or other wise mentally disabled. More than forty percent are African American and disproportionate numbers are Native American, Latino, and Asian." (American Civil Liberties Union) It does not seem fair that only these people are dying. The Constitution states that everyone should be given a fair trial. These statistics do not prove to me that these people had a fair trial. Everybody makes mistakes. If a jury makes a mistake and a person is falsely accused of murder when they find out they messed up they want to take the

Life in a High School

Cliques are small groups of between two and twelve individuals. Cliques are small enough that the members feel that they know each other better than do people outside the clique. Members of a clique share common activities and friendships. They are social settings in which adolescents hang out, talk to each other, and form closer friendships. Groups of friends, called cliques can be important for social upgrading, but in most cases the enormous power and effects of these cliques can create alienation, exclusion, and destructive results. In my high school, as well as every other high school in America there are social groups of individuals, called cliques, that effect every individual whether they are an insider or an outsider. Generally there are the cool cliques, the athletic cliques, the freak clique, the skater clique, the smart clique, and the average clique. Almost everyone finds their place in one of these cliques, but there are always a few outsiders who go through high school never knowing where they belong. these are the people who are constantly ridiculed, picked on, and talked about day in and day out. The effects can be devastating, even deadly. In Littleton, Coloraldo two outcast teenagers came into school one day and began shooting, targeting the athletes and other students who had made their lives awful by ridiculing them constantly. Seniors Eric Harris and Dylan Klebold stormed their suburban Denver school with guns and bombs last April 20, killing 12 students and a teacher before taking their own lives(Kenworthy 1). Augustana University education professor Larry Brendtro explained kids who feel powerless and rejected are capable of doing horrible things(Cohen 4). A high school student, Jason Sanchez understands why the two outsider snapped by saying If you go to school, and you dont have friends, it drives you to insanity(Cohen 4). So what do these lonely outcast kids do if they are rejected by everyone Roger Rosenblatt discusses in his article, Welcome to the Works of the Trench Coat, how kids will discover self-worth by hating an enemy(Rosenblatt 1). The kids of Columbine for example look alike; they conceal differences. People who are attracted to clans and cults seek to lose their individuality and discover power and pride in a group. As individuals, the killers Eric Harris and Dylan Klebold, were vulnerable, taunted by the other tribes in school– the cliques, the athletes– as geeks and nerds(Rosenblatt 1). The end result as a young girl involved in the murders reported was, He just put a gun to my head, and he started laughing and saying it was all because people were mean to him last year(Rosenblatt 1). The social warfare of cliques has no limits or boundaries; anything can and will happen. Columbine High School is only one example of how high school cliques can be damaging to teenagers. At Glen Ridge High School a group of jocks raped a retarded woman. In that attractive upper-middle-class New Jersey suburb, thirteen jocks were present in the basement where the young womans body was penetrated by a baseball bat and a broomstick. The country was sickened by the inhumanity of a bunch of guys who were among the most admired and envied young men in their community and high school (Lefkowitz 653). These star athletes were not even afraid of being punished. They told their friends and schoolmates of the incident not trying to hide it at all. Athletes are treated as kings of the school. This is not only true for the athletes, but for the cheerleaders too. In the article by Adam Cohen he says While others plod through high school, they glide: their exploits celebrated in the pep rallies and recorded in the school paper and trophy cases(Cohen 2). Another high school student Blake McConnell says that The jocks and the cheerleaders have the most clout, they get out of punishment — even with the police. Joe Blow has a wreck and has been drinking, and he gets the book thrown at him. The quarterback gets busted, and he gets a lighter sentence ( Cohen 2). How does this prepare the so called stars for the real world whenever they are just an average working man How does this make the normal and less special students feel What about the smart people, where is their recognition for all their hard work and success Cohen noted that assemblies to honor the best students rarely lasted twenty minutes. The school yearbook displayed ten photographs of the most mediocre football player. But the outstanding scholar was lucky to get one grainy photo ( Lefkowitz 654). This is leaving the impression on many teens that the jocks are superior while everyone else is below them. What kind of lasting impression will this leave on the kids Lefkowitz stated in her essay, I received hundreds of letters from people, some in their seventies and eighties, who recalled how excluded they felt when their schools anointed one group of guys as leaders(Lefkowitz 654). High school teaches us all many important lessons that stay with us all through our life, and sometimes the lessons inside the classroom are the least of it. High school is a chance for us all to invent ourselves. High school for me was the best of times, even though when I was still in school and someone told this to me I just thought they were crazy. My senior prom, the football games, the pep rallies, and even the trouble I got into are all memories that I will look back upon for the rest of my life and just think how great life was then. I guess though while I was caught up in all the fun and games of high school I never stopped and noticed all the people being left behind. The people who remember high school as pain and suffering. The outsiders that we all picked on not stopping to realize what we had cost them, the best years of their lives.

Effect Of Leadership Traits On Employee Performance Commerce Essay

Within every company a leader is needed. Sometimes even more than one, when a company has grown and therefore exists out of multiple divisions. These leaders are of import because they give the company a way to caput to, and teach the employees to make this in the best possible manner. Particularly when a company has merely been started, it is really of import to do certain that everyone does his very best and knows precisely what to make in order to diminish the opportunity of failure of the new venture. Past research has shown that entrepreneurship forms a important portion of every economic system in many ways ( Van Praag & A ; Versloot, 2007 ) . For illustration, the generating of employment ( Sutton, 1997 ) , economic growing through entrepreneurship ( Carry & A ; Thurik, 2003 ) , the importance of little and average sized houses associating to invention ( Biggs, 2002 ) and economic value creative activity ( Parker, 2004 ) . Therefore, it is really of import to cognize every bit much about this whole procedure as possible. This can merely lend to increasing the per centum of successfully started ventures. Due to the fiscal crisis in 2009, the per centum of failures in new ventures has been really high ( Graydon, 2010 ) . As this has great effects for the economic system, it is of import that this per centum goes down in the coming old ages. A batch of research has already been done on this topic, but clear grounds on leading in combination with enterprisers that start up a new co mpany is still losing. In order to acquire to cognize more about the leading of enterprisers, this research is aimed at the enterprisers in Amsterdam who have merely started their ain company. The research is done to acquire an reply to the inquiry of what leading traits lead to the biggest opportunity of conveying the new venture to a success. In Amsterdam, there are a batch of new start-ups every twelvemonth and together with the easy handiness to these enterprisers and their companies ; this environing signifiers an outstanding possibility to make research in. Hopefully this survey leads to a more clear vision on the success traits of enterprisers who have to move every bit leaders as good in conveying their start-ups to a success. The following subdivision, which is the theoretical model, will discourse the bing literature on leading traits, the features that distinguish an enterpriser from a non-entrepreneur and recent literature on leading combined with entrepreneurship. Section three is the methodological analysis subdivision and discusses everything that is of import in making this research. For illustration, the research method that is traveling to be used, and the features of the research.Theoretical model2.1 LeadershipIn the yesteryear, there have been 100s of articles written on leading. In the 1950 ‘s, Bales based his research on the differentiation between two different leading attacks, viz. : task-oriented manner and the interpersonally oriented manner. The task-oriented manner is frequently associated with the ‘initiation of construction ‘ as construction was what it was all about. The interpersonally oriented manner is related with consideration, and was based on common relations hips with followings and so on ( Eagly & A ; Johannesen-Schmidt, 2001 ) . Later on, research was frequently aimed at the differentiation between democratic and bossy leading ( Vroom & A ; Yetton, 1973 ) and therefore differentiated leaders who allowed followings to take part in determination devising and those who did non ( Eagly & A ; Johannesen-Schmidt, 2001 ) . Burns ( 1978 ) argued that some of import leading traits were losing. Three new types of leading were recognized. The transformational leader was person who stood for individualized consideration, rational stimulation, inspirational motive and idealized influence ( Saunders et al. , 2007 ) . The 2nd type was the transactional leader, person who brought the contingent wages system, to merely honor followings if they had performed good plenty, and merely changed something when it did non work, which was called direction by exclusion ( Saunders et al. , 2007 ) . The last type was the Individualistic leader. This leader was pe rson who likely did non hold adequate accomplishments or motive and therefore avoided doing determinations and being responsible. Apart from spliting leaders into the manners they follow, the can be differentiated on leading traits. There are besides many surveies aimed at the features of people that make them a leader. Although none of these results were precisely the same, the most articles did come to the similar features that differentiate a leader from person who is non. Stogdill ( 1974 ) and House & A ; Baetz ( 1979 ) showed that leaders tend to be higher in ( 1 ) intelligence, ( 2 ) laterality, ( 3 ) assurance, ( 4 ) energy and ( 5 ) cognition of the undertaking than non-leaders. Throughout these surveies, the most of import inquiry was what the most of import features of a born leader are. But research besides showed that it is non about holding these features, but how to utilize them in a manner that makes you effectual as a leader. Therefore, Kouzes and Posner ( 2007 ) did research on the leading behavior and found that this behavior can be identified through five factors, viz. ( 1 ) animating a visio n that is shared, ( 2 ) patterning the manner, ( 3 ) promoting the bosom of the followings, ( 4 ) disputing the procedure and ( 5 ) enabling others to move. Different types of undertakings frequently ask for different leader features and behaviors. Therefore it is of import that a leader knows how to accommodate to certain fortunes. This makes him other than his followings and therefore person with whom they can interact. Fiedler ( 1967 ) argues through his eventuality theory that the ultimate leading behavior is dependent upon the state of affairs. Thereby, Fiedler has besides stated that experience is more of import than intelligence in some hard state of affairss. This means that leaders besides grow as they gain working experience, and utilize this experience in state of affairss that require more than unconditioned traits. This is really of import because of the fact that the leader influences all kinds of employee variables like organisational committedness, occupation satisfaction, public presentation and so on. ( Kouzes & A ; Posner, 2007 ) . Research done on leading has a batch of things in common with research in other Fieldss. One illustration is the research on traits of a specific type of individual. This research is besides done in the field of employees as followings of leaders, but besides for illustration the features of employees in combination with occupation satisfaction and organisational committedness. Another illustration is research on features of people with regard to working-groups or calling direction. One of the most similar types of research compared to surveies on leading is the research on enterprisers. What are the traits of a existent enterpriser? Why is one enterpriser more successful so another? In a batch of ways this research is comparable.2.2 EntrepreneurshipThe research on entrepreneurship and leading is really similar in many ways ( Ensley et al. , 2006 ) . The facet that is most similar is the hunt for traits that makes person good and efficient in his function. This type of research is ca lled the â€Å" traits attack † . Throughout the old ages, a batch of research was done on two facets within this traits attack. The first facet is the consequence of the state of affairs on enterprisers ( e.g. Kirzner, 1997 ) or leaders ( e.g. Wofford and Liska, 1993 ) and the 2nd facet is the behavior of enterprisers ( e.g. Shaver and Scott, 1991 ) or leaders ( e.g. Bass, 1990 ) . Merely like with a leader, an enterpriser besides influences the public presentation of his organisation. He can be the 1 who makes the difference between success and failure of the new venture. Some research workers say that this is due to his features that divide him from others, such as risk-taking leaning ( Stewart & A ; Roth, 2001 ) , high self-efficacy ( Chen, Greene & A ; Crick, 1998 ) or to detect chances that others do non ( Alvarez & A ; Busenitz, 2001 ) . But other research workers say that it is due to the behavior of the enterpriser that concerns increase the opportunities to win, so how he uses these features ( Bass, 1990 ) . Either manner, a batch of similarities are found between leaders and enterprisers, which makes it interesting to analyze the combination of the two.2.3 Uniting leading with entrepreneurshipAs leaders and enterprisers have a batch in common, it is non a surprise to cognize that the two can be combined. In fact, research has showed that being a leade r while get downing a new venture, and therefore being an enterpriser, is of import in order to acquire the most out of the company. As stated above, leaders are able to act upon facets such as the motive, productiveness, and committedness of employees and therefore act upon the overall public presentation ( Kouzes & A ; Posner, 2007 ) . As enterprisers are depending to a great extent on the employees in the beginning stage of the new venture, it is of import to convey up the best out of these employees ( aˆÂ ¦ . ) . Different types of leaders have different kinds of influence on their followings. This is an of import thing to maintain in head while making research. Each type of leading has its ain advantages and disadvantages and therefore respond different to a specific state of affairs. For illustration, transformational and magnetic leading are frequently related to a better public presentation of workgroups and organisations ( Saunders et al. , 2007 ) . Another illustration is that a transformational leader wants to be seen as ‘the great leader ‘ and does non pay any attending to the state of affairs or his followings, while a democratic leader is person who joins the group and works every bit difficult as the remainder ( Saunders et al. , 2007 ) . In order to allow the employees work every bit efficient as possible it is of import to cognize what type of leader tantrums best in the start-up. Up till now there has been little old research on the combination of leading traits and entrepreneurship. Therefore there are few researches to trust on for now. What is utile is research that has been done on leading in different state of affairss. One of the most of import in this field is that of Fiedler, who did research on different factors act uponing leading public presentation. For illustration, his cognitive research theory, which was aimed at stressful-situations, leading intelligence and leading experience. Although non everyone was to the full convinced by these theories ( Vecchio, 1992 ) , there have non been any cardinal challenges of the theory.Methodology3.1 Research sceneThe scene of this research is based on Amsterdam and its milieus. This is because of the fact that these companies are easy accessible for the research worker. Thereby comes that a batch of the enterprisers in Amsterdam are united in several associations. For illustration, the ‘Ondernemersgroep Amsterdam ‘ , ‘het Ondernemershuis ‘ and MKB Groot Amsterdam. Furthermore, the ‘Kamer new wave Koophandel ‘ , which is Dutch for Chamber of Commerce, is located near the Centre of the metropolis. These associations will likely be able to give all the information that is needed for this research.3.2 Research featuresThis research will be done through utilizing a cross-sectional attack. This can be described as a ‘snapshot ‘ clip skyline. Due to clip restraints and informations handiness it is likely the best option to utilize. Of class, being able to analyze alterations and developments of certain companies over clip, and therefore utilizing a longitudinal attack, would likely take to even more specified consequences ( Saunders et al. , 2007 ) , but this option would take excessively much clip. So, informations from companies that are in their first or 2nd twelvemonth of concern will be used, this information is still recent and should non t ake to much problem when roll uping. Thereby comes that the enterprisers should still be clearly cognizant of how they fulfilled their leading functions, with regard to the traits of their leading type. Clear should be that the degree of analysis is on the firm-level and that the research is practice-driven. This research could be valuable to the theoretical scientific discipline as it is seeking to acquire a better apprehension of certain phenomena, but besides in pattern where enterpriser and leader can larn from. By cognizing more about the traits of each function, and particularly for enterprisers how to unite the traits of these two functions could be really valuable ( Ensley et al. , 2006 ) . The social relevancy therefore plays a bigger function than the scientific relevancy. The companies that are traveling to be used in this survey are likely all established within Amsterdam and its milieus. Besides, they have to be registered at one or more of the above mentioned associations so that the entree to the enterprisers and necessary informations will be available. Variables used in this survey will be traits of enterprisers as they are besides perceived as leaders within their company, and the company ‘s public presentation. For many companies the term of one or two old ages after start-up will likely be excessively short to be able to talk of a success or failure of the company. Therefore, the company ‘s public presentation as in being good on path compared to what was planned earlier, the opportunity of lasting the following old ages, and employee public presentation will be used to mensurate the company ‘s state of affairs.3.3 RestrictionsThe end of this research is to acquire an indicant of the effects of leading traits on the public p resentation of little entrepreneurial ventures that have merely started. In this first bowl, it is of import to allow the employees be every bit efficient as possible, as most of the resources such as money and clip are limited and rivals are frequently watching the company closely to do usage of any errors made. A quantitative attack will be used through looking at company ‘s public presentation in relation to leading traits of the enterprisers. Hopefully, afterwards the cognition on this particular topic will be deepened and be utile for scientific discipline every bit good as in pattern. For illustration, a relation between the traits of a leader that inspires his employees to work towards a certain end every bit efficient as possible is extremely related to a good executing start-up. In Figure 1, a schematical position on the research is given. The normal line between ‘leadership traits ‘ and ‘start-up public presentation ‘ is the chief relation that will be investigated in this research. The flecked lines, between ‘leadership traits ‘ and employee public presentation, and between 'employee public presentation ‘ and start-up public presentation ‘ will likely besides be investigated, although this is still a spot unsure because of the fact that garnering the information will be comparatively hard and there may besides be excessively many other facets that could act upon this relationship. Therefore, a spot more research has to be done foremost on the 'employee public presentation ‘ as a moderating/mediating variable.Figure 1. A schematical position on the variables and their relation to each other.An advantage of this survey can be that the combination of leading and entrepreneurship on the degree of little sta rt-ups is still comparatively bleary and therefore has the possibility to open up a new portion of this field. Thereby comes that this research is chiefly aimed to better the cognition of enterprisers on leading traits that are helpful in the beginning stage of a company, which means that the state of affairs can be seen from the houses point of position, alternatively of a theoretical point of position which sometimes differs excessively much from world ( Saunders at al. , 2007 ) . This survey will hold a batch of restrictions. One of them is the sample size. Through bounds on clip and resources it will be impossible to acquire a really big sample size. Amsterdam will be taken as the chief country of the start-ups of which informations will be gathered. Thereby comes, that there is a bound on the sum of start-ups, as the figure of new ventures depend on all kinds of variables and conditions. Besides, non all informations may be available for every company due to privacy grounds or unwillingness to collaborate of enterprisers. Another restriction can be the usage of Amsterdam as the chief part of entrepreneurial activity. Several factors within Amsterdam and its surrounding can be of influence on the consequences and therefore consequences do non hold to be generalizable in other parts of the universe. Amsterdam being a big metropolis, the capital of the Netherlands, and for illustration a big tourer attractive force. Furthermore, This research is aimed at start -ups and therefore is non generalizable for every company, as several resources such as clip, money and employees are frequently really limited.Small Planning tabular arrayEventGet downing day of the monthCompleting day of the monthDiscoursing the subject, with Ms. van Eerde and supervisor 6thJanuary Bettering the literature reappraisal and methodological analysis 7thJanuary Middle of February Get downing with study ‘s etc, because this will ever take longer than expected.
