Effects of Peer Pressure Essay Example for Free

Effects of Peer Pressure Essay Everyone wants to belong , to be accepted . This is a major reason why teenagers feel pressurized to go along with what others are doing the so called peer pressure. Teenagers are going through tremendous physical and emotional changes as they change from childhood to young adults . There are new responsibilities to be faced , exams to be taken and of course new relationships to be faced . There is rebellion against the rules and ideas that parents impose and so they flock together almost in desperation in some cases. As young people spend more time with their peers outside the family home there are opportunities to do things that they haven t done before such as trying out substances drugs , alcohol and so on . Young people at this stage in their lives often feel very insecure are the changes that are happening to them normal ? Why haven t they got bigger breasts a longer penis , a boy /girl friend and all the rest ? They may even be unsure of their sexual orientation By giving in to peer pressure and uniting in a common `uniform whether of clothing or language they feel stronger and more normal , and meeting with others going through similar problems reinforces their egos , even though this may go against the norms of society in general. As they mature , obtain jobs , move away from the area in which they grew up perhaps , the effects of peer pressure will diminish . see more:essay on peer pressure They will hopefully realize that misusing drugs is not a good thing . Gradually , as they become surer of themselves , most people feel able to make their own decisions as to which music they prefer , clothes to be worn , even their opinions on world issues will be less affected by what their friends think or do . They will make their own decisions about taking drugs or getting drunk . They will feel accepted for who they are , what they are capable of , and though peer pressure continues to affect most people to some extent its effects tend to lessen as maturity occurs Peer pressure has a very strong influence on our decisions; so it is capable of bringing about great change, whether its for the good or the bad of the situation or person. Peer pressure exists for all ages. Pre-teens and teenagers face many issues related to conformity and peer pressure. They are pulled between the desire to be seen as individuals of unique value and the desire to belong to a group where they feel secure and accepted. The result is that often teens reject family or general society values, while feeling pressure to conform rigidly to the values of their peer Your peers are the people with whom you identify and spend time. In children and teens, they are usually, but not always, of the same age group. In adults, peers may be determined less by age and more by shared interests or professions. Peer pressure occurs when an individual experiences implied or expressed persuasion to adopt similar values, beliefs, and goals, or to participate in the same activities as those in the peer group. Peer groups have so much influence, especially with adolescents, because, nomatter how inappropriate it seems to adults, belonging to a group really doesgive something significant to the young person. Peer groups provide a placewhere children feels accepted, where they can feel good about themselves, andwhere their self-esteem is enhanced. Some psychologists also point out thatlife become simpler when we conform to expectations. Young people tend to gravitate toward other young people with the same problems and in the same situations as themselves and where they feel they will be understood and accepted.There is a very, very strong need to satisfy that thirst for unity and for acceptance. The feeling of belonging is a very powerful force that can outweigh ties to church, school, family, or community. In addition to the feeling of belonging and not being alone or socially isolated, some characteristics that peer groups offer which make them attractive and that families may lack are: (1) a strong belief structure; (2) a clear system of rules; and (3) communication and discussion about taboo subjects suchas drugs, sex, and religion.

CHAPTER 1: INTRODUCTION Introduction A Liquid to Liquid hydrocyclone is a static machine that use centrifugal force and apply it on the liquid mixture which will make the separation of heavy and between the mixture components (light and heavy components) of this liquid. A Liquid to Liquid hydrocyclone will normally consist of the below three parts (see figure 1) Cylindrical section Conical base The angle DSeriesCyclone3 2 Figure : Diagrams of a Hydrocyclones The key difference between the centrifuges and Liquid to Liquid Hydrocyclones that the Hydrocyclones are passive separators where it capable to apply the modest amounts of centrifugal force, but the centrifuges are called dynamic separators which are usually able to concern more centrifugal force than The Hydrocyclones. Another difference between hydroclones and centrifuges devices is the cost where the Centrifuges are expensive machines because its often need sophisticated control but the Hydrocyclones doesnt contain moving parts and it usually doesnt contain controls systems and because of this it at all so they are lesser cost devices There are any types of a hydrocyclone where it could be used to separate solids from liquids or to separate liquids mixture of unlike density. The hydrocyclone is used in various applications in many industries, from degritting sewage sludge to removing oil droplets from produced water. The governing principles are difficult to quantify because of the complexity of the fluid dynamics with multiple phases in highly swirling flows. The majority of applications are in the processing of mineral ores however, and experience has helped develop a basis for predicting the hydrocyclone classification performance in these duties. The factors that affect performance, both process and hydrocyclone design, will be covered in this paper. The focus will be on providing information that an engineer who is designing a hydrocylone system will find useful. A cutaway of a hydrocyclone is shown in Figure 2. The slurry enters the area of the hydrocyclone called the inlet head from the inlet feed pipe. The slurry is introduced next to the wall of the cylindrical inlet, which induces a swirling action. Figure : Hydrocyclone Cutaway  [1]   This action helps develop the inertial forces that enable the classification of particles within the hydrocyclone. The slurry is further accelerated in the conical sections of the separator. The swirling action produces a low-pressure vortex in the center of the hydrocyclone where the finer, lower-mass particles migrate. The relatively light particles are removed with the overflow stream by an upward swirling flow through the vortex finder. The heavier particles are removed with an underflow stream by a downward swirling flow through the apex region of the hydrocyclone classifier. Figure : Hydrocyclone, Tangential Velocity Distribution  [2]   Figure : Hydrocyclone, Tangential Velocity Distribution  [3]   Figure : Hydrocyclone, Tangential Velocity Distribution  [4]   Figures 3 and 4 shows the mean axial and tangential components of the velocity at different cross-sections in the upper portion of a 250-mm diameter hydrocyclone (Petty et al., 2002). These single-phase numerical calculations were developed using the Reynolds averaged Navier-Stokes (RANS) equation, and standard transport equations for the Reynolds stress (RSM model) and the turbulence dissipation. The simulation imposes a backpressure on the overflow and underflow streams to avoid the air core. The Reynolds number based on the effective diameter of the feed entry and the volumetric flow rate of the feed stream is about 200,000. Figure 5 shows the pressure distribution predicted by the simulation. The results, which are qualitatively similar to experiments by Kelsall (1952) and to multi-phase flow calculations reported by Devulapalli and Rajamani (1994), predict a Rankine vortex flow with a maximum tangential velocity near the radius of the vortex finder (see Figure 4). This feature distinguishes hydrocyclone flows from other swirling flows encountered in centrifugal separators. As illustrated by Figure 5, the swirling action of the flow field causes a lower pressure to develop in the core of the hydrocyclone. It is noteworthy that the Computational Fluid Dynamics (CFD) simulation captures the important qualitative flow features of a hydrocyclone classifier. Applications of Liquid to Liquid Hydrocyclone: In pulp and paper mills. In the sector of water treatment industry. In petroleum industry sector to separate oil from water or water from oil. In Food industries. In chemicals industries. Basic Parameters for Standard Cyclone The definition of a standard cyclone is that cyclone which has the proper geometrical relationship between the cyclone diameter, inlet area, vortex finder, apex orifice, and sufficient length providing retention time to properly classify particles. As with the involutes type design, the graphs and mathematical relationships shown for proper selection and sizing of cyclones apply to the standard cyclone geometry. The main parameter is the cyclone diameter. This is the inside diameter of the cylindrical feed chamber. The next parameter is the area of the inlet nozzle at the point of entry into the feed chamber. This is normally a rectangular orifice, with the larger dimension parallel to the cyclone axis. The basic area of the inlet nozzle approximates 0.05 times the cyclone diameter squared. The next important parameter is the vortex finder. 3.jpg Figure : Hydrocyclone Cutaway  [5]   The primary function of the vortex finder is to control both the separation and the flow leaving the cyclone. Also, the vortex finder is sufficiently extended below the feed entrance to prevent short circuiting of material directly into the overflow. The size of the vortex finder equals 0.35 times the cyclone diameter. The cylindrical section is the next basic part of the cyclone and is located between the feed chamber and the conical section. It is the same diameter as the feed chamber and its function is to lengthen the cyclone and increase the retention time. For the basic cyclone, its length should be 100% of the cyclone diameter. The next section is the conical section, typically referred to as the cone section. The included angle of the cone section is normally between 100 and 200 and, similar to the cylinder section, provides retention time. Figure : Involuted Feed vs. Tangential Feed  [6]   The termination of the cone section is the apex orifice and the critical dimension is the inside diameter at the discharge point. The size of this orifice is determined by the application involved and must be large enough to permit the solids that have been classified to underflow to exit the cyclone without plugging. The normal minimum orifice size would be 10% of the cyclone diameter and can be as large as 35%. Below the apex is normally a splash skirt to help contain the underflow slurry. Construction of the Liquid to Liquid Hydrocyclone: A typical Liquid to Liquid hydrocyclone made of a conically shaped vessel this vessel open at its apex or underflow this is fixed to a cylindrical section which has feed inlet at the tangent. The top of the cylindrical section is congested with a plate which exceed through the axial mounted pipe of overflow and the pipe is lengthen into the body of the hydrocyclone by small removable section known as the vortex finder the function of this vortex finder to prevent the short-circuiting feeding directly into the overflow. The bottom of the vortex finder is protruding below the feed chamber. The feed chamber and the cones are lined inside with the rubber or synthetic linings due to the abrasive nature of most metallurgical slurries. The lined material is made from hard rubber such as neoprene or urethane and the apex is fixed with a concentric hardwearing synthetic rubber (See Figure 8). Figure : Construction of the Hydrocyclone Working Principle of Liquid to Liquid Hydrocyclone: The Liquid to Liquid hydrocyclone generally is a closed vessel that designed to make conversion for the incoming velocity of the liquid into rotary motion. This is achieved by direct inflow tangentially near to the top of a vertical cylinder where this will spins the entire contents of the cylinder and creating centrifugal force in the liquid so that the Heavy Liquid will go Outward toward the cylinder wall, where they farm and a spiral down the wall to a port in the bottom of the ship and in the light of Liquid will move toward the axis of the hydrocyclone (see figure 9) where they will move toward the outlet which is exist at the top of the vessel. 1 Figure : Working principle of the Liquid to Liquid Hydrocyclone CHAPTER 2: SIZING AND SELECTION OF HYDROCYCLONES Performance In determining the proper size and number of cyclones required for a given application, two main objectives must be considered. The first is the classification or separation that is required, and the second is the volume of feed slurry to be handled. Before determining whether these objectives can be achieved, it is necessary to establish a base condition as follows: 1. Feed liquid water at 20O C. 2. Feed solids spherical particles of 2.65 sp gr. 3. Feed concentration less than 1% solids by volume 4. Pressure drop 69 kPa (10psi). 5. Cyclone geometry standard cyclone as described above Classification Historically, classification has been defined as the particle size of which 1% to 3% reports to the cyclone overflow with coarser particles reporting to the cyclone underflow. Recent investigations have defined classification as the particle size of which 50% reports to the overflow and 50% to the underflow, or the so-called D50C point. Figure 10 shows the typical relationship between particle diameter and the percent recovered to underflow. The portion of the curve near the 50% recovery level is quite steep and lends itself readily to determining an accurate particle diameter. Examination of the recovery curve near the 97% to 99% recovery level shows that the curve is nearly horizontal and a small differential could change the micron diameter considerably. Figure 11 also shows that the actual recovery curve does not decrease below a certain level. This indicates that a certain amount of material is always recovered to the underflow and bypasses classification. If a comparison is made between the minimum recovery levels of solids to the liquid that is recovered, they are found to be equal. Therefore it is assumed that a percent of all size fractions reports directly to the underflow as bypassed solids in equal proportion to the liquid split. Then each size fraction of the actual recovery curve is adjusted by an amount equal to the liquid recovery to produce the corrected recovery curve shown in Figure 10. As the D50C point changes from one application to another, the recovery curves shift, along the horizontal axis. Figure : Particle Diameter VS. Particle Recovery  [7]   In order to determine a single graph which represents the corrected recovery curve, the particle size of each size fraction is divided by the D50C value and a reduced recovery curve can be plotted, as shown in Figure 11. Investigations have shown that this curve remains constant over a wide range of cyclone diameters and operating conditions when applied to a slurry containing solids of a single specific gravity and a typical or normal size distribution such as those encountered in most grinding circuits. Equation 1 gives a mathematical relationship which can be used to calculate the reduced recovery. This recovery, along with the bypassed solids, is used to predict the complete size distribution for the underflow product. Where Rr = Recovery to underflow on corrected basis. X = Particle diameter /D50C particle diameter. Figure : Reduce Recovery  [8]   In designing comminution circuits the objective is to produce an overflow from the cyclone which has a certain size distribution, normally defined as a given percent passing a specified micron size. An empirical relationship shown in Table 1 is used to relate the overflow size distribution to the D50C required producing the specified separation. The relationship of this table is for typical or average grinding size distributions and may vary slightly Depending upon the grinding characteristics of the ore itself. The separation a cyclone can achieve can be approximated using Equation 2. The D50C (base) for a given diameter cyclone is multiplied times a series of correction factors designated by C1, C2, and C3. Table : Relationship of D50C to Overflow Size Distribution Required Overflow Size Distribution (percent Passing) of Specified Micron Size Multiplies (To be Multiplied Times Micron Size) 98.8 0.54 95.0 0.3 90.0 0.91 80.0 1.25 70.0 1.67 60.0 2.08 50.0 2.78 Example: Produce an overflow of 80% passing 149 microns (100 meshes). Multiplier from Table 1 at 80% passing = 1.25. Micron size for application = 149 microns (100 mesh). D50C required = 1.25149 = 186 microns for application. This D50C (base) is the micron size that a standard cyclone can achieve operating under the base conditions and is given in Figure 12 or calculated from Equation 3. For example, a 25.4 cm (10 in.) diameter cyclone has a base D50C point of 24 microns. Figure : Cyclone Diameter V.s D50 (For Typical Cyclones)  [9]   Where D = Cyclone diameter in cm. The first correction (C1) is for the influence of the concentration of solids contained in the feed slurry. The graphical representation of this correction is shown in Figure 13 and can be calculated using Equation 4. Figure 13 indicates that the level of percent solids is extremely important in determining the proper separation, as the higher the concentration the coarser the separation. It should be pointed out that this correction is a relative measure of slurry viscosity and is affected by such things as the size of particles present as well as particle shape. For example, a feed that contains a large amount of clay would tend to shift this curve to the left and result in a coarser separation, whereas the absence of fines would shift the curve to the right and result in a finer separation. Many other variables such as liquid viscosity also affect this correction. Where C1 = Correction for the influence of cyclone feed concentration. V = Percent solids by volume of cyclone feed. Figure : Correction for Feed Concentration  [10]   The second correction is for the influence of pressure drop across the cyclone as measured by taking the difference between the supply or feed pressure and with overflow pressure. Pressure drop is a measure of the energy being utilized in the cyclone to achieve the separation. It is recommended that pressure drops, whenever possible, be designed in the 40 to 70 kPa (5 to 10 psi) range to minimize energy requirements as well as reduce wear rates. This is especially true for coarse separations usually associated with primary or secondary grinding circuits. The correction for pressure drop is shown in Figure 14 and can be calculated from Equation 5. As indicated, a higher pressure drop would result in a finer separation and lower pressure drop in a coarser separation. Where C2 = Correction for influence of pressure drop. à ¢Ã‹â€ Ã¢â‚¬  P = Pressure drop in kPa. Figure : Correction for Pressure Drop  [11]   The next correction is for the effect that specific gravity of the solids and liquid have on the separation. Since the cyclone does not actually achieve a size separation but rather a mass separation, the specific gravity of the particle is extremely important in determining the separation. It is especially meaningful in applications where the mineral has a higher specific gravity than the gangue material which allows better liberation of mineral particles at a coarser overall separation size. It has been found that Stokes law can be applied to determine particle diameters which would produce the same terminal settling velocity for a particle of known specific gravity in a liquid of known specific gravity as compared to a particle of 2.65 specific gravity in water. This relationship is shown in Figure 15 and can be calculated using Equation 6. Where C3 = Correction for influence of specific gravity GS = Specific gravity of solids GL = Specific gravity of liquid (normally 1.0) Figure : Correction for Solids Specific Gravity (in water)  [12]   The cyclone diameter, along with the three corrections of percent solids, pressure drop, and specific gravity, are the main variables necessary for preliminary sizing and selection of cyclones. Other variables, such as the vortex finder and inlet size, also have an effect on separation. For example, a larger vortex finder size would tend to coarsen the separation, whereas a smaller size would tend to achieve a finer separation. Due to this fact, most cyclones have a replaceable vortex finder with different sizes available. Vortex finder diameters vary from a minimum of about 25% of the cyclone diameter to a maximum of about 45%. The inlet area also shows the same effect as the vortex finder, but not as pronounced. The apex size also has an effect on separation but the effect is minor unless the apex is too small and becomes a physical constraint, forcing material into the overflow. Cyclone retention time is also a minor factor influencing cyclone performance. Within limits, increased retention time would help achieve a finer separation; whereas reduced retention time would coarsen the separation. The retention time of the cyclone can be altered by either changing the length of the cylindrical section or by changing the cone angle. There are numerous other variables which also have an effect of separation; however, these variables are relatively minor and may be neglected for the preliminary sizing and selection of cyclones. Flow Rate The second main objective which must be considered is to provide adequate cyclone capacity for the application. The volume of feed slurry that a given cyclone can handle is related to the pressure drop across the cyclone. The relationship between flow rate and pressure drop for several different sizes of standard cyclones is shown in Figure 16. As shown, the flow rate increases as the pressure drop increases. In order to utilize this graph, the pressure drop used for calculating the separation is used to determine the flow rate for the cyclone diameter which was also used for determining the separation. The flow rate is then divided into the total flow for a specific application to determine the number of units necessary. Since the flow rate given in Figure 16 is for water rather than slurry, it should be mentioned that slurry normally increases the capacity of a cyclone over that shown for water; however, for preliminary estimates this factor can be neglected. This will result in th e number of cyclones calculated being slightly higher than those actually needed. Approximately 20% to 25% standby cyclones are recommended for operational as well as maintenance flexibility. The vortex finder size and inlet area of a cyclone also have an effect on the volumetric flow rate that a given cyclone can handle. Larger vortex finders or inlet areas would increase the capacity, whereas smaller vortex finders or inlet areas would decrease the capacity. The shaded area in Figure 17 corresponding to each standard cyclone gives the approximate range of capacity for each cyclone. Figure : Pressure Drop V.s Volumetric Flow rate  [13]   Shown that an underflow density of 50% to 53% solids by volume is typical for primary grinding circuits, whereas an underflow density of 40% to 45% solids by volume is normal for regrind circuits. Therefore, an underflow density can be assumed which establishes the total flow rate that must report through each cyclone apex. Figure 17 shows the approximate flow rate for a given diameter apex orifice. Figure : Apex Capacity Diameter VS. Flow rate  [14]   Operational and Design Considerations One of the most important considerations is to insure that cyclones are installed properly. A detailed list of Dos and Donts is given in a later chapter. Feed Piping and Distribution A most important consideration for a given cyclone system is proper delivery of the slurry to the cyclone or cyclones. It has been found that a pipe size which produces a line velocity of 200 to 300cm/sec (7 to 10 ft/sec) is high enough to prevent particles from settling, even in horizontal sections, but low enough to minimize wear. Normally for a single cyclone installation the inlet pipe size of the manufacturers recommendation produces a velocity in this area. If the slurry is to be distributed to a number of cyclones operating in parallel, extreme care should be given to the design of the distribution system, and a radial type of manifold is recommended. This is a system where the cyclones are fed from a central circular chamber. When properly designed the central chamber becomes a mixing area and the line velocity should be lowered to approximately 60 to 90 cm/sec (2 to 3 ft/sec). This will help insure that each cyclone is fed with the same slurry concentration as well as the sa me particle size distribution and also will reduce wear rates. Using the radial manifold also makes it easier to install standby cyclones. Should an inline type manifold be utilized, the cyclones do not receive good distribution. It is typical that the high mass particles or coarser particles tend to pass the first cyclones and report to the final cyclone. This results in the last cyclone receiving a higher feed concentration of coarser particles, which accelerates the wear of the last cyclone as well as produces a coarser separation due to the higher feed density. Also, the last cyclone, once shut off, becomes difficult to restart because the solids will tend to pack into the feed pipe. For applications where the separation is not critical or one in which the feed concentration is extremely low, an inline manifold is acceptable and is much less expensive than the radial type. Pressure Drop Calculation As mentioned earlier, the pressure drop across a cyclone is measured by taking the difference between the feed pressure and the overflow pressure. If the overflow is discharged at near atmospheric pressure as recommended, the feed pressure is the same as the pressure drop. Cyclone selection provides the pressure drop required, and for pump calculations this must be converted to meters of slurry which can then be added to the static and friction heads to determine the total dynamic head for the pump. Equation 7 is used for conversion of pressure drop to meters of slurry. Where M = Meters, slurry. à ¢Ã‹â€ Ã¢â‚¬  P = Pressure drop, kPa. G = Sp gr of slurry. As stated, it is recommended that both the overflow and underflow products be discharged at atmospheric pressure. Should the overflow be discharged against a positive head, some of the fluid which normally reports to the overflow is forced to report to the underflow. This does not have a major effect on classification but does increase the amount of bypass solids and reduces underflow density. Should the overflow be discharged at a point lower than the feed entrance, a possible siphon can be established which would cause a breakdown in classification and could bring larger particles into the overflow. A large siphon effect could actually dislodge a worn liner which in turn would plug the overflow piping. Siphons can be prevented by installing a vent pipe on the overflow piping of each cyclone. The underflow should also be discharged at or near atmospheric pressure. Should the underflow be discharged at a negative pressure, the effect would be similar to a positive pressure at the cyc lone overflow. If the underflow is discharged against a positive pressure, the amount of flow is reduced and a larger apex must be selected in order to insure that the SUMP/PUMP Design Another chapter covers the selection and sizing of slurry pumps and should be consulted for more detailed information concerning sump/pump design. Specifically regarding cyclone applications, the feed slurry being delivered to a cyclone should be as steady as possible with regard to both volumetric flow rate and slurry density. Unsteady feed conditions such as severe pump surging or extreme variations in slurry density are very detrimental to good cyclone performance. In general, a sump/pump system for a cyclone application should have a sump with as much depth as possible and a minimum cross-sectional area consistent with the pump manufacturers recommended retention time. A sump of this design will normally eliminate pump surging by allowing small variations in sump level well above the minimum pump suction level. The small cross-sectional area will reduce the buildup of solids in the bottom of the sump and help prevent large sections of the settled solids to slough into the pump su ction and plug either the cyclone feed line or the cyclone apex. Therefore, a tall sump with a small crosssectional area provides much smoother operation. Apex Discharge Pattern An Important part of cyclone operation is being able to observe the type of pattern that the cyclone apex is producing. An apex operating at atmospheric pressure should produce a cone shaped discharge with an angle of 20O to 30O and a hollow center. If the cyclone consistently produces a high angle cone spray, the apex orifice should be reduced in size to maximize the slurry density being discharged. On the other hand, should the cone spray be void of the hollow center and resemble a rope, then the apex is too small and oversize material may be reporting to the cyclone overflow. In this case, a larger apex orifice should be installed. CHAPTER 3: DESIGN VARIABLES, HYDROCYCLONE GEOMETRY Hydrocyclone Inlet Design Hydrocyclones designed prior to 1950 featured outer wall tangential feed entry and 12-15 mm thick rubber liners. This design was not adequate for fine separations or for abrasive slurry applications. Most hydrocyclone manufacturers have redesigned their inlets to include some form of involutes, ramped or scrolled feed style and all of these provide a measured advantage in hydrocyclone performance compared to earlier tangential designs. Figure 18 illustrates the various types of hydrocyclone feed entries. The inlet opening or cross-sectional area of the orifice feeding into the cylindrical section of the inlet has an effect on capacity as well as D50, and most hydrocyclone models have several options to increase or decrease this area based on the desired flow rates and cutpoint. In general, the larger inlet area, the higher the hydrocyclone capacity and the larger predicted D50. Cylinder Section Typically hydrocyclones have a cylinder section length equal to the hydrocyclone diameter. This can be a separate section or integral to the inlet head. Figure 19 illustrates a hydrocyclone without a cylinder section plus hydrocyclones with a single and double cylinder. While the longer cylinder section provided greater residence time and thus more capacity, it also reduces the tangential velocity. The added cylinder length results in minimal improvement in hydrocyclone separation and will increase hydrocyclone capacity at the same pressure by 8-10%. Larger 660-840mm diameter hydrocyclones typically have shorter cylinder sections.

Comparing Chinese Culture in Amy Tans The Joy Luck Club and Kitchen Go

Chinese Culture Exposed in Joy Luck Club and Kitchen God's Wife  Ã‚  Ã‚        Ã‚  Ã‚   Traditional Chinese customs are described in great detail in Amy Tan's books. This rich culture adds interesting and mesmerizing detail to the intricate stories of both The Joy Luck Club and The Kitchen God's Wife.    Traditions are apparent throughout all of the stories in The Joy Luck Club. One of the first instances is in the story from Ying-Ying St. Clair entitled "The Moon Lady." Ying-Ying is describing the Festival of the Moon Lady, a festival dedicated to the lady who lives on the moon and once a year comes down to earth to grant your secret wish--something you want but cannot ask. This excerpt describes proper traditional dress (ornate clothing saved for special occasions), delicious foods such as rabbits feet and mooncakes (saved for special occasions), fireworks, and family gathered all together. This is one of the most richly detailed and culturally authentic stories in the novel.    The other story that strikes the reader as containing vivid culture and tradition is Lindo Jong's "The Red Candle." This story, like Winnie Louie's, describes in great detail the customs of arranged marriages. Lindo Jong begins by talking about the village matchmaker coming to her housewhen she was two years old.

Chicago Gangs and History

This paper deals with gang violence in the city of Chicago since the beginning of time. It takes a deep look into the history of Chicago gangs and how they interact today. Also the past problems the City of Chicago made when dealing with gangs and the problems that gangs today have and how Chicago has the worst gang problem in the country. Also how gangs have turned themselves into big, and lucrative enterprises most known for money. Also stated are possible solutions to stop or reduce violence of the gangs that all start off with teaching the young kids about gangs and gang prevention. Chicago Gangs, Then and Now with Solutions Jimi Hendrix once said â€Å"Every city in the world always has a gang, a street gang, or the so- called outcasts. † Every city deals with gangs but some cities are worse off than others. Chicago is infamous for gang violence and problems dealing with gangs. For some getting to school in the Chicago land area can even be a matter of life and death because of the gangs and their violent ways (Belluck, 2000). Throughout history gang violence infested the city of Chicago, and it continues to create problems today; hopefully solutions planned by the city can stop the violence. Race shaped Chicago gang history. â€Å"African Americans were crowded into to the south side ‘Black Belt’† (A brief outline of Chicago’s gang history, para 2). As the First World War ended, blacks came back to Chicago and fights broke out to find jobs. The Democratic Party led by Mayor Richard J. Daley decided to keep segregating the city (Brief outline). The blacks were separated by an expressway and an 18 story housing project. Separating races caused violence to sky rocket. The segregated areas proved more nationalistic for their area and defended it to the core. Gang leaders were constantly thrown into jail so they had to find ways to keep a lucrative business. The Chicago Police Department declared war on gangs in the 1960’s and the prisons soon became overpopulated (Brief outline). Gangs reorganized and many combined their gangs into one bigger enterprise. Gangs were mostly run from prisons during the 1970’s and on (Brief outline); therefore one could not escape the gangs. Gangs shaped Chicago early on. Gentrification is displacing gangs and causing turf wars. Gentrification and the tearing down of public housing in Chicago left many gangs homeless (Brief outline). Due to this, gangs battle over land and housing, known as turf wars. The violence rises, along with the number of deaths. Therefore police attempt to limit the gangs, but that also leads to fighting and violence with police. The whole cycle involves violence and is vicious. Chicago has the biggest gang problem in the country (Thomas & Bass, 2009). â€Å"There are more gang members per citizen in Chicago than anywhere else in the country† (Thomas, 2009, para 4). The average Chicago gang leader is 43, convicted of murder and lives in the suburbs. That leader on many occasions directs his gang from jail (Main, 2006) and 95 percent of inmates in the Cook County Jail are gang members (Thomas, 2009). Gangs are everywhere today just like they use to be. The high number of gangs causes violence and deaths to rise in Chicago. â€Å"Gangs have morphed from social organizations into full-fledged criminal enterprises† (Thomas, 2009, para 5). Gangs are highly sophisticated and more dangerous then ever. The number one reason to join a gang is money; and 95 percent of gangs profit comes from drug dealing (Thomas, 2009). Gangs do not worry about others and civilians, but rather money and their respective gang. Dealing with gangs is very dangerous. Even coming into contact with gangs can be dangerous. There are a wide variety of ethnicities and groups of gangs. â€Å"Gangs can not be attributed to one ethnic or cultural group† (Decker, 2009, pg 404). The high number of gangs again leads to turf wars because of a need for land and housing. Due to all of this violence police can not stop gangs alone; people must contribute to the effort (Thomas, 2009). Gangs can not be stopped but reducing the violence can be done. It will require Chicagoans participation and officers doing their job but it will make gangs less apparent in the city. Gang prevention must start with kids. The young people must be taught about gangs and the consequences of them since they are the future. They need to be taught the right way so they will not become involved with gangs and eventually gangs will die out. Schools should offer after school and summer jobs programs in order to get kids off the street after school and learning. Schools also should teach about gangs and offer drug prevention programs (Main, 2006). Kids are the key to stopping gangs and if taught correctly it can happen. Going after leaders of gangs is beneficial. Superintendent Jody Weis put in an ordinance saying, â€Å"That if gangs resort to violence, police will go after their leaders (Tarm, 2010). Gang leaders will be held accountable for all the actions of their members. It is likely that a leader might become infuriated after going to jail so many times for actions of his gang members that he might leave the gang. If this happens a couple of times the gang might diminish or vanish completely. This is one possible way to stop gangs. Controlling â€Å"hot spots† is key in stopping gangs. An ordinance was passed saying that police can arrest suspected members of a gang if they don’t leave and area an officer tells them to (Belluck, 2000). A similar ordinance was passed that allows officers to tell people to remove themselves from an area and to stay eye distance away (Johnson, 2000). This again allows officers to watch â€Å"hot spots† and can destroy gangs business in an area causing them to lose money. It also allows gang members to keep being jailed and off of the streets for a period of time so they can not commit crimes or violence. This will limit gang’s enterprises. Gang violence infests the city of Chicago but solutions can stop the violence. Chicago has the worst gang problem in the country but with the help of police and members of society it can be lowered. Kids must be taught from a young age about gangs and ordinances that make it hard for gangs to conduct business must be passed. Gangs can be stopped but it is no easy task. Chicagoans will have to work very hard but gangs can become lesser of a problem or maybe even obsolete one day.

How does deep brain stimulation help with Parkinso Essays - Medicine

How does deep brain stimulation help with Parkinso Essays - Medicine How does deep brain stimulation help with Parkinson disease Deep brain stimulation is a surgical procedure used to treat a variety of disabling neurological symptoms such as: tremor, stiffness, slowed movement and walking problems. What does deep brain stimulation involve? Deep brain stimulation involves implanting very fine wires with electrodes at their tips into the brain. These are connected to extensions that are tunneled under the skin behind the ear and down the neck. They are connected to a pulse generator (a device like a pacemaker), which is placed under the skin around the chest or stomach area. When the device is switched on, the electrodes deliver high frequency stimulation to the targeted area. This stimulation changes some of the electrical signals in the brain that cause the symptoms of Parkinson's. Your specialist or Parkinson's nurse will programme the device using a small portable computer. It may take several months to fully programme the stimulator and adjust your Parkinson's medication to get the most benefit from the surgery. Deep brain stimulation is a 'non-destructive' type of surgery, so it doesn't destroy any part of the brain. It's also reversible in many cases if no damage occurs during surgery. Surgery may take place under general anesthetic (when you are asleep) or you may be awake for part of the procedure - it depends at which Centre you have the surgery. What Are the Advantages of Deep Brain Stimulation? advantages . First, it does not require purposeful destruction of any part of the brain and therefore, has fewer complications than thalamotomy and pallidotomy . In addition, the electrical stimulation is adjustable and can be changed as the person's disease changes or his or her response to medications change. No further surgery is necessary to make the adjustments. Another significant advantage of deep brain stimulation relates to future treatments. Destructive surgery, such as thalamotomy or pallidotomy , may reduce the person's potential to benefit from future therapies. For example, future brain cell transplantation may be of great help to people with Parkinson's disease. There is concern that a pallidotomy or thalamotomy may prevent patients from benefiting from brain cell transplantation. This would not be the case with deep brain stimulation, as the stimulator could be turned off. Deep brain stimulation is a relatively safe procedure. The procedure can treat all the major symptoms of Parkinson's disease . Daily living tasks and quality of life are also improved. With subthalamic nucleus stimulation, medications can usually be reduced. The stimulator can also be turned off at any time if deep brain stimulation is causing excessive side effects. Possible Disadvantages : A small increased risk of infection. The implantation of any foreign object in the body carries that risk. Additional surgery may be needed if the equipment stops working or for battery replacement. Additional time on the part of the patient and health care provider to program device and adjust medications What can you expect after surgery? The surgery usually requires a 2-day hospital stay. Most people recover completely within about 6 weeks. It is best to discuss the risks associated with your neurologist because there are many risk factors, including underlying medical conditions.

All About the French Regular Verb Passer (to Pass)

All About the French Regular Verb 'Passer' ('to Pass') Passer (to pass) is a very common and useful regular -er verb, by far the largest group of verbs in the French language.

Essay on Frazer&Patti Candy Example | Topics and Well Written Essays - 750 words

On Frazer&Patti Candy - Essay Example Managing marketing pursuits requires evaluation and critical assessment of markets and consumer buying behaviors in those markets. The manager at the Candy Council had critically accounted for this provision beforehand. Antonella critically reviewed advertising pursuits and strategies employed by New Century Advertising to determine the impact of advertising on candy consumption. Loopholes emerged as to the effectiveness of advertising that the Candy Council engaged in. The council engaged in huge advertisement financing for candy consumption. While some advertisement bids realized positive results, there were times when consumption declined with exacerbating advertisement pursuits (Frazer & Patti, 2000). According to Antonella, the role of advertising for the council’s pursuits was unclear. However, it was also clear that the council was in dire need for advertisement given the market trends in candy consumption. For this reason, the three finalist advertisement agencies need ed critical scrutiny for effectiveness and efficiency. All the three finalists had their strongholds and weaknesses. According to the summarized agency profiles, the three finalists were competitive enough in their own way for the advertisement task. However, their ratings according to the council’s advertising manager would play a central role in choosing the agency that would oversee the Candy Council’s advertisement activities. The ineffectiveness that Antonella attributed to advertisement emanated from the comparison of candy consumption figures to the level of investment in advertisement that the council was making. In several instances, huge investments yielded negative results in terms of candy consumption, a scenario that depicted no need for investment. This was the primary concern for Antonella. The council’s advertisement manager, therefore, remained torn between need and no need for advertisement. Up to 70 percent growth in candy gift giving had been realized for a period of ten years by the time Antonella started working for the council (Frazer & Patti, 2000). What was not clear to her is the role of advertising in the realization of that growth. However, even with Antonella’s failure to comprehend the role of advertisement in the realization of that growth, advertisement had actually contributed to the 70 percent growth realized. The Candy Council remained vibrant in creating awareness and marketing candy products, without necessary advocating for specific candy brands. In this regard, this pursuit had mobilized candy consumers into candy gift giving, even when no specific candy products had been highlighted by such advertisements. New Century Advertising had worked with the Candy Council for several years. In this regard, the agency was fully integrated into the council’s activities unlike the other two advertisement agencies. The evaluation conducted by Antonella depicted inadequacies in the duty performance o f New Century Advertising. Antonella’s agency ratings showed that the other two finalists were better than the current agency. However, the fact that New Century Advertising understood the candy market environment that the council operated in was overlooked. Given the fact that all the three advertisement agencies were dealing with edible consumer products, changing the current agency would be relatively insignificant. New Century Adve

The Case for Reparations Article Essay Example | Topics and Well Written Essays - 250 words - 3

The Case for Reparations Article - Essay Example The Mississippi region had many cases of lynching colored Americans, unnecessary arrests, slavery, discriminatory learning, and discrimination against access to resources, among other issues, (p.2, 3, 6). The article was written to expose the trauma experienced by colored Americans to diverse Americans race but the African Americans, in particular. Perhaps, AP published this article to address the American government and other legal authorities to seek justice for the atrocities carried out on the black American race. Overly, the target audience might be the global populace since racial discrimination, slavery, and reparations affect international the society. When reading through this article, a variety of evidences is showed to explain the central themes of the story. However, this paper only focuses on a few indications outlined in the article. For instance, the AP reported that Mississippi involved lynching black populace (p.2) and whoever resisted legal arrangements was gravely injured or killed (p.3). There was the lack of legal protection for the black people (p.5), and land currently developed as a country club in Virginia was forcefully acquired from blacks (p.6). In addition, Ross explains that there was meager support for educating the black race that resided in Mississippi (p.7) and that he failed to receive a legitimate mortgage just because there was no financing for black people (p.18).

Stem Cell Research from Christian Perspective Essay

Stem Cell Research from Christian Perspective - Essay Example Stem cell research's eligibility and necessity is doubted through moral and ethical arguments, while the scientific approach tries to convince the humans that the primary goal is to make them healthier, to find the cure to cancer and many other benefits. The main reason why stem cell research causes such a controversy is because, in the stage in which the blastocyst is extracted, the embryo dies. Since it is impossible to remove the blastocyst without killing the embryo, certain religions believe that stem cell research is evil. This is because there is an uncertainty as to when life begins, and whether it begins from the time of conception, or it begins only after the fetus has begun to develop. This is where society is distinctly split, between the scientists and the religious ethicists. One of the positive aspects of stem cell research that goes in favor of the scientists is the fact that they can do a great deal to help scientific studies, especially in finding the cures for diseases. Scientists have found that, by experimenting with stem cells, they can possibly find cures for chronic and fatal diseases such as diabetes, Parkinson's, Alzheimer's, heart disease, cancer, multiple sclerosis, spinal cord injuries, and many more. By performing stem cell research, scientists will be able to help hundreds of thousands of people who are affected by diseases such as these. This can be done by taking the unspecialized stem cells and removing certain protein coats, and therefore turning it into a certain type of cell (such as a cardiac cell or brain cell). These cells can then are transplanted into the needed areas and replace the existing, non-working cells to cure the person of that illness. During the process through which a stem cell is removed from an embryo, and the embryo is sacrificed. The argument many people make about this issue is that it is morally wrong. Many Catholics feel that it is not right to kill the embryos because they are human beings. Scientists believe it is not their part to judge whether it is morally right or wrong. Their job is to make the cures and this is one way to do it. Many people think it is wrong to kill humans to help other humans. This opinion is supported by four passages from Scriptures (Benson 2004): Genesis 1:26-27 - Humans are made in God's image Deuteronomy 5:17 - We are not to unjustly take human life Psalm 139:15, 16 - God knew us as individuals in our mother's womb and even before Matthew 1:20 - Our Savior was once a single cell embryo The debate over stem cell research is closely related to the cloning issue. As Dr. David Stevens has noted, the embryonic clone would be the patient's genetic twin displaced in time. It would be a human being because it has the chromosomes of a human perfectly formed for that stage of development. At that point in time, the embryo is self-directed and, if left in the proper environment, it will continue development through gestation, birth, maturity and eventually natural death, just like all humans (Benson 2004). The question here is when does the life begin according to the Creator Christians and the representatives of other religions are confident that the stem cell research

Wayne Williams Assessment Research Paper Example | Topics and Well Written Essays - 500 words

Wayne Williams Assessment - Research Paper Example The route taken by the accused could be a human rights preference, and it is also highly probable that he took that route to dump the body of one of his murder victims. The taunts that Wayne directed at the investigators cannot be overlooked as they could have two implications to the case. The investigations were slated at a time when race related matters were at an all time high. This could mean that Wayne was reacting to the maltreatment that he received which was a direct result of his race. On the other hand, it could be that he was highly corky and overconfident because he knew that there was no evidence that would eventually link him to the murders (Deadman, 1982). This paper will support the conclusion that Wayne Williams was guilty in the murder of some of the victims, as an outcome of fiber evidence analysis and linkage. Despite all the numerous challenges in the provision of evidence, in the above stated claims, there are certain aspects of the case that remain hazy. It is not possible for Wayne to claim that he was travelling to scout and recruit Cheryl Johnson, who could not be traced. There is no existing evidence that shows that they had previously communicated or even agreed to meet on the said date. Evidence that was gathered from his home intimated that he had taken time to acclimatize himself on the procedures to follow when trying to beat a polygraph test. It is a result of non-binding evidence that the prosecutors thought it prudent to rely on fiber evidence (Deadman, 1982). It is prudent to note that fiber evidence has contributed greatly in drawing resolute conclusions in criminology. The process, analysis, correlation and merging of fibers has the capacity of solving mysteries that would have otherwise remain unresolved. In the case of Wayne, the fibers processed and analyzed from the murdered victims were of a rare kind (Ramsland, 1991). However, investigators were able to

Development of Comprehensive Integrated Marketing Communication Mix - Assignment Example Other than messages regarding the cure of the Prostate Cancer the charity should also develop messages about creating awareness in the masses. Stage 5: One should identify the channels and who to hit what stake holder. May be message for each stake holder is same but there is difference in approaching them so other than proper message identification of proper channel also matters. This also includes how the message development helps the supporters and teams of the organization to achieve the objectives of the organization and help them in creation of the awareness regarding the disease. Stage 1: Background – The UK Charity Sector The UK charities’ market is large, with more than 169,000 ‘main’ charities registered with the Charity Commission in June 20071. A ‘main’ charity is defined by the Charity Commission as one that is: â€Å"required to prepare accounts and to send an Annual Return to the Charity Commission or, if their income is less th an ?10,000, inform the Commission of changes to the information held on the Register of Charities.† Based on the latest available financial information reported by each of these ‘main’ charities, their total aggregate annual income, according to the Charity Commission, amounts to just over?46 billion. As would be expected, many of the charities are very small, with an annual income of less than ?10,000, which is below the Charity Commission’s reporting threshold. Although these are still required to keep accounts, they do not have to submit them as a matter of course to the Commission. Around 90% of total annual charity income is controlled by the largest 5% of the charities. These are all subject to more stringent annual reporting and audit requirements. There are 722charities with an annual income in excess...In assignment Development of Comprehensive Integrated Marketing Communication Mix, the author describes man principles and backgrounds of this moder n marketing trend in order to create critical outlook and answer next questions: How it can be used nowadays?

Binge Drinking Among College Students and Consequences Essay Example for Free

Binge Drinking Among College Students and Consequences Essay Binge drinking is a problem that has continued to have a toll on the lives of college students despite efforts by the government and school administrators to curb the trend. Many studies have been conducted to reveal the facts behind binge drinking in colleges and campuses. It is clear that for the problem of binge drinking in colleges to be resolved, it must all start by understanding the factors that influence college students to engage in this behaviour and the impacts that binge drinking have had on the lives of college students. This is because students who do engage in binge drinking have their reasons to justify their behaviour but often have failed to recognize the magnitude of risks that they are exposed to by binge drinking. Among the government initiatives to reduce this problem has been to increase the national drinking age though this has not had much impact on the level of binge drinking among college students according to several studies. It is worth noting that many students have been indulging in binge drinking with the excuse that it is normal as per the culture in their colleges. There are other factors that influence college students to binge drink including environmental, social, developmental, and cognitive factors. Though most students who binge drink defend their behaviour by citing the positive side of binge drinking such as curbing stress and elevating self-confidence, the consequences are often costly and regrettable. This essay provides an argument on the factors that influence college students to indulge in binge drinking, including the various false beliefs about alcohol consumption. In addition, the essay will shed light on the consequences of binge drinking and show that contrary to the tendency of college students to glamorize binge drinking, it is a risky and costly endeavour. Binge drinking has been defined as heavy episodic alcohol consumption in which men end up taking five or more drinks in a si tting while women take four or more drinks in a sitting (Nelson and Wechsler 287). The prevalence of binge drinking on college campuses has remained high, posing serious health, academic, social, and legal implications. In order to understand binge drinking, it is worth mentioning that drinking is measured in terms of frequency or quantity. While quantity refers to how much, frequency is concerned with measuring how often consumption takes place. A drinking behaviour qualifies as binge drinking if large quantities of alcohol are consumed within a short time frame (Binge Drinking). By looking at the history and prevalence of binge drinking among college students, it leaves no doubt that changing drinking age over time has had little impact on the prevalence of drinking on college campuses. Beer drinking among college students is not a new phenomenon as tales dating back to 19th century are told of college students engaging in drinking. A survey conducted by Yale University researchers in 1949 gave an idea of the prevalence of drinking on college campuses. The survey found that 6% of women and 17% of men engaged in drinking more than once per week. In the 1960s and 70s the minimum drinking age in many states was set at 18 to agree with the requirement that those joining the military ought to be old enough to drink (Dietz 88). However, this action only paved way for increased drinking on college campuses given that now drinking was legal. The government had to act swiftly to arrest this trend and in 1984, the minimum drinking age was set at 21. Even then, the level of drinking remained almost the same as most college students had attained this age and thus regarded themselves as being entitled to drink (Krock). Drinking rates over the past 20 years have remained relatively at the same level and now it is estimated that 80-90% of college students are into drinking. Heavy drinkers constitute 15-25% of college students and 44% of college students report frequent or occasional binge drinking (Dietz 88). These statistics are indicative of the fact that binge drinking is a problem that is deep rooted in other factors such as the kind of cultures in colleges, environmental, cognitive, and developmental factors. Therefore, altering the national drinking age while it has shown positive impacts in the general population in terms of decreasing the prevalence of binge drinking, cannot offer a comprehensive solution to the same problem in colleges (Krock). The culture of drinking on campus has contributed a great deal to the high prevalence of binge drinking. While acknowledging the fact that unique cultures exist among individual colleges, these individual cultures harbour certain sub-cultures that encourage excessive consumption of alcohol. Within these sub-cultures, a common message is perpetuated that drinking is a normal and essential component of social interaction. Therefore, many college students conduct themselves in a manner that agrees with what the prevailing culture dictates (Ho pe and Ham 727). The culture of drinking on college campuses is composed of a number of elements. The first element is drinking events which encourage students to indulge in drinking to mark certain events (Dietz 89). In the same way that universities and colleges have a strong sense of tradition, the drinking culture has deep roots in most colleges. Therefore, many students engage in binge drinking in the process of honouring certain events that to them require people to drink in order for the commemoration to have real meaning (Dietz 89). In as much as the culture of drinking in many colleges and universities is difficult to do away with, it has only served to make students make the wrong decision of involving themselves in heavy episodic drinking characteristic of binge drinking. The bottom line is that in the disguise of marking particular events, many college students involve themselves in binge drinking thus exposing themselves to detrimental consequences. Drinking games is an element of drinking culture in colleges that have contributed to the high prevalence of binge drinking. In some colleges, students have tended to glamorize the aspect of drinking alcohol to the extent that drinking gam es are held in which students compete in drinking alcohol. Some drinking games are highly competitive while others just dictate rules regarding how much participants are expected to drink (Dietz 89). Nevertheless, the fact is that whether a drinking is highly competitive or not, by the virtue of portraying drinking as totally harmless, such games have encouraged binge drinking to the detriment of many students. It is true to say that in order to create opportunities for excessive drinking, students in many colleges have perpetuated drinking games entrenched in the culture of drinking. A good example of a drinking game in colleges is Beer Pong in which 6-16 cups partially filled with alcohol are taken by each team. The person playing the game is expected to throw a ping-pong ball aiming at the opponent’s cup across the table. If the ball lands into the partially filled cup, the opponent has to drink the content. The team that runs out of cups first is considered the loser (Dietz 89). By considering the nature of such a game, it is prudent to note that its objective is to encourage excessive drinking judging by the number of cups involved. Therefore, students who get involved in such games more often than not end up binge drinking in the name of having fun but in reality exposes themselves to negative consequences. Another important factor which makes college students to indulge in binge drinking is the kind of choices they make in terms of the groups they want to identify themselves with given that college students are eager to have a sense of belonging. One study targeting to investigate how college students seek to have a sense of belonging revealed that those students who joined Greek organizations drank consistently and more heavily than those who did not join Greek societies (Hensley). Greek societies are known to be prevalent in colleges and often entice students to join them in order to gain a sense of brotherhood or sisterhood. However, many students who agree to join these organizations are exposed to a life of excessive drinking in the disguise of obeying induction rituals. Eventually, the life of excessive drinking becomes part and parcel of these students (Dietz 90). While it is understandable that many students joining college are eager to identify themselves with particular groups or organizations, it is expected of them to make prudent decisions which would not compromise their studies and their lives in college. Unfortunately, many students have ended up in binge drinking through making inappropriate decisions only to realize when things go terribly wrong. Athletics is also another element of college culture whereby, students take the moment as an excuse for drinking but then end up binge drinking. When students drink excessively during sporting events, they often cause incidences and fall in trouble with authorities. Drunken fans are known for causing chaos during and after games irrespective of the game outcome. Consequently, property may be damaged and both bystanders and the rioters suffer serious injuries (Dietz 91). For students who binge drink because of sporting events, it is just a flimsy excuse and the consequences are often regrett able. Therefore, drinking games, sporting events, traditional drinking events, and Greek organizations are the elements of the culture of drinking on college campuses which make many students involve themselves in binge drinking. Unfortunately, the notion that alcohol is essential for complete social life on campus is a misconception whose consequences are harmful. Apart from the culture of drinking, college students are influenced into binge drinking by environmental, developmental, and cognitive factors. Regarding the environment, logic dictates that the way someone behaves is more often than not influenced by what is going on in the surrounding. Therefore, when students drink in environments where people have carried alcohol to drink, drinking games are being played, hard alcohol is available in plenty, and the people around are intoxicated; binge drinking can always be predicted. On the other hand a drinking environment where drinking is taking place in a family setting, in the context of dating or where food is available, studies have shown that in such environments, binge drinking is very unlikely (Dietz 92). Though this suggestion carries weight, it is paramount to reckon that studies that have been done on such environmental implications on the likelihood of binge drinking have been largely correlational. What this means is that though the first kind of environment may contribute to the occurrence of binge drinking, it is also a possibility that those students who indulge in binge drinking are already present in such an environment. Therefore, it would be difficult to determine for instance whether playing of drinking games in such an environment resulted from the presence of binge drinkers or whether students ended up binge drinking because of being in an environment where people played drinking games (Dietz 92). Nevertheless, it leaves no doubt that depending on the kind of environment that students expose themselves to, the likelihood of binge drinking either increases or decreases. Cognitive factors constitute another influential force which has led many college students to develop binge drinking behaviour. The cognitive influences are deeply rooted in misleading beliefs about alcohol, the notion that binge drinking is something that is acceptable, and misinformation about the effects of excessive alcohol consumption. Regarding the false beliefs or myths that some college students confidently hold on to, there are those who believe that everybody is engaging in binge drinking and thus experiences similar negative consequences (Binge Drinking). This is a misguided thought because a significant percentage of college students do not engage in binge drinking. At the same time, the negative consequences experienced by those who indulge in binge drinking vary and cannot be the same. For instance, according to the direct effects model, binge drinking consequences are determined by both the drinking beliefs and the binge drinking tendencies. Going by this model, students who hold more risky myths such as â€Å"everybody is doing it† is more likely to experience harsher consequences. This is because; such students are often lured into thinking that binge drinking cannot make them suffer physical harm. Consequently, they are more likely to involve themselves in highly risky behaviours after binge drinking and hence experience more severe consequences compared to those who do not hold such a myth (Turrisi, Wiersma and Hughes 343). Another myth among binge drinkers is that binge drinking enhances sexual performance and sex appeal. The fact is that binge drinking predisposes students to risky sexual behavior in which some students may engage in unprotected sex which can lead to the contraction of HIV/AIDS and other sexually transmitted infections (DeSimone 2). In fact binge drinking causes disorientation and those who engage in it are incapacitated from making rational decisions when they are drunk. The belief that their sex appeal is enhanced is misguided. There is also the belief among those who attempt to justify binge drinking that binge drinking is a remedy for stress and that it can enhance social interaction. On the contrary, binge drinking has been associated with hangovers and even suicidal thoughts. Binge drinking does not enhance social interactions but instead it triggers quarrels, arguments, fights, and incidences of blacking out and vomiting (Wechsler). Others believe that alcohol is not harmful to the body. Again, such a belief is the total opposite of the fact since alcohol consumption has been associated with serious health consequences including alcohol poisoning. The other aspect of cognitive influences is that some students will engage in binge drinking because they perceive the behavior as acceptable in the eyes of their parents and friends. In other words, they find consolation in the idea that binge drink is not bad after all since their parents and friends do not show any disapproval of the behavior (Dietz 94). Developmental factors also help to explain why college students engage in binge drinking. It is worth noting that once students reach this level of maturity, they naturally develop the desire to be regarded as mature adults who can make independent decisions and be responsible for the consequences of their actions. Therefore, binge drinking behaviour among many college students emanate from this desire to assert their adulthood. Moreover, college students are usually at their prime physically and thus they feel much confident in terms of being able to withstand the impacts of drinking alcohol which may also lead them into drinking excessively (Dietz 91). Though regarded as normal development, the fact that college students are likely to regard as adult hypocrisy anti-drinking messages from people, only puts them at more a vulnerable position. It is also noteworthy that college students are at a stage of critical social and emotional development. For instance, this is a time that they experience a higher level of autonomy since their parents are not around to monitor them. This increased freedom makes many students to make autonomous decisions and often experiment with behaviours that their parents had forbidden them. Moreover, many college students are still continuing with the process of devel oping their identity and in the process, often indulge in behaviours such as binge drinking in search of more sensational experiences (Hope and Ham 727). Peer influence is usually at the centre of identity development as students try to fit in new environments with a sense of belonging. Therefore, given that in many colleges students are confronted with a drinking culture, it is not a wonder that some result to binge drinking. However, many students fail to realize that with more freedom comes the need to be more responsible. This is because too much freedom without a sense of self-control or restraint is harmful. In this regard, in as much as certain developmental factors are normal, it cannot be justified as the excuse for engaging in heavy drinking. Binge drinking has a wide range of negative consequences which many college students fail to foresee before plunging themselves into the risky behaviour of binge drinking. Some students do not think that binge drinking can lead to any immediate negative consequence while others lean on the belief that alcohol does not pose harm to the body at all. Such notions are null and void given th at bingers are often caught in a wide range of crises such as engaging in unplanned or unprotected sex and getting into trouble with the authorities. In addition, bingers are more likely to engage in dangerous acts such as driving while drunk than nonbinging drinkers. Drunk driving is a major cause of car accidents and many young people have lost their lives because of it (Nelson and Wechsler 290). Some of the beliefs about the benefits of binge drinking among college students include the idea that by binge drinking, one can get more sexual opportunities. On the contrary, binge drinking only serves to make bingers behave irresponsibly and engage in risky sexual behaviours such as unplanned or unprotected sex. Consequently, some may contract STIs and HIV/AIDS which is a very high price to pay for being irresponsible. Unwanted pregnancy is another possible outcome of binge drinking which adds to the social burden and compromises the studies of the affected student. Contrary to the notion that binge drinking helps to relieve stress, one of its notable consequences has been the increased risk of committing suicide among college studen ts. Given that 67% of suicide incidences in colleges result from alcohol abuse, the idea that binge drinking causes relaxation is a nonstarter (Wechsler). The health consequences associated with binge drinking are severe. For instance, liver cancer is a fatal illness which can lead to death if not treated early. Another terrible consequence of binge drinking is alcohol poisoning which is a health condition that is not reversible once it occurs. This is a fact which is contrary to what people believe that alcohol poisoning can be reversed by drinking black coffee, walking, sleeping, or taking a cold bath. Time is the only factor that can determine whether the condition will get better or worse. However, due to the high level of alcohol in the blood, there may be no time for the alcohol level to decrease. Instead, the increase in blood alcohol level may continue even after quitting drinking. Consequently, death can result from interruption of breathing functions or the patient may choke on his/her vomit while unconscious (Do You Understand Binge Drinking?). Binge drinking causes students to be left behind in school work and academic performance of binge drinkers is rendered poor. For instance, due to hangovers and disorientation that comes with excessive drinking, students often fail to complete their assignments or to attend lectures. Consequently, their grades continue to deteriorate and their academic life may become a nightmare (Hensley). Such outcomes are contrary to the notion among young binge drinkers that they have the ability to control the effects of excessive drinking. The fact is that the consequences of binge drinking are stronger than one may try to imagine and many students only regret later when it is too late. The second hand effects of binge drinking are also real and come in the form of insults, sleepless nights, unwanted sex advance, arguments, and a ssaults (Wechsler). From this discussion, it leaves no doubt that binge drinking is highly prevalent on college campuses, something that has been contributed by different factors. This is supported by the evidence of many studies showing that despite the national drinking age being increased to 21, binge drinking especially among female students has increased. The consequences of binge drinking are detrimental. This has been witnessed in the form of the escalating cases of road accidents which has cost many lives of college students. Despite the belief among many college students that alcohol consumption enhances social interaction and sex appeal, binge drinking results in quarrels, arguments, and risky sexual behavior. In addition, students who binge drink have often found themselves in trouble with authorities. Poor academic performance due to inability to focus is a big problem among binge drinkers. Contrary to the belief that alcohol releases stress, statistics have proved otherwise. In fact, incidences of suicide have been on the rise among binge drinkers. The notion among binge drinkers that they are able to control the impacts of alcohol is a nonstarter given the high incidences of rape, assault, and vandalism among college students who binge drink. Regarding the culture of drinking in most colleges, this is something that bingers lean on as an excuse for their behavior. Issues of autonomy and the urge to identify with particular groups though real only imply that individual students must make prudent choices amidst the pressure. It all has to start by correcting the misconceptions and wrong attitudes among college students. Nevertheless, binge drinking remains a nagging issue whose consequences are a threat to many generations. Annotated Bibliography 1. Binge Drinking. n.d. Web 25 Nov 2011 . This article presents an argument regarding the way binge drinking has been defined by researchers and helps the reader to understand the controversy surrounding what actually amounts to binge drinking. It acknowledges that binge drinking is characterized by repeated intoxication with alcohol which makes a person become careless and abandon his/her responsibilities. In this case, it is useful in this research paper in terms of shedding light on what amounts to binge drinking and the possible consequences. It also alludes to the fact that binge drinking is still prevalent on college campuses. However, it points out that most of the research results about binge drinking on colleges have not reflected the real picture of the situation. 2. DeSimone, Jeff. Binge Drinking and Risky Sex among College Students. 2010. Web 25 Nov 2011 . This article is useful in this research to the extent of addressing one of the main consequences of binge drinking; risky sexual behaviour. The information in the article is presented in form of a report based on research aimed at finding out the relationship between binge drinking and risky sexual behaviour among college students aged between 18 and 24 years. Its findings that binge drinking increases promiscuity and inability to opt for safer sex such as condom use help to build on the paper’s argument. However, it fails to recognize other numerous negative consequences of binge drinking besides risky sexual behaviour. 3. Dietz, Christine M. Development of Binge Drinking Behavior in College Students: A Developmental Analysis. Graduate Journal of Counseling Psychology (2008): 1(1), pp. 86-96. The journal presents valuable information on the factors that influence college students to engage in binge drinking. It extensively addresses the culture of drinking in most colleges which many students lean on as an excuse for intoxicating themselves with alcohol. In addition, the journal discusses the developmental, cognitive, and environmental factors that play a big influential role in binge drinking. The information in the journal is quite useful in this research paper as it presents a broad picture of what has led to the high prevalence of binge drinking on college campuses. However, it falls short of addressing the details of the consequences of binge drinking. 4. Do You Understand Binge Drinking? 2011. Web 25 Nov 2011 . This is an article that explores in a brief but precise manner, what binge drinking is, the myth surrounding binge drinking, and the main health consequences of binge drinking. It helps to build the argument that contrary to what many college students perceive as being invincible to harm, binge drinking is a monster that induces slow death regardless of age. 5. Hensley, Laura G. College Student Binge Drinking: Implications for a Constructivist Approach to College Counseling. Journal of College Counseling (2001): Vol 4. T he journal covers the most fundamental elements presented in this research paper in the form of an argument. It begins by explaining the prevalence of binge drinking and the factors causing this trend such as students joining Greek societies and succumbing to peer pressure. It then highlights the behavioural, health, and academic negative consequences that result from binge drinking. Though the information is useful in building an argument, the journal presents it in form of a report or literature review. 6. Hope, Debra A and Lindsay S Ham. College students and problematic drinking: A review of the literature. Clinical Psychology Review (2003): Vol 23, pp. 719-759. This journal review explores the problem of excessive drinking among college students by citing the findings of a number of studies that have been conducted in the past. It acknowledges the importance of considering frequency and quantity when defining binge drinking. Besides highlighting the consequences of binge drinking, it also explores other aspects such as gender difference in the likelihood of excessive drinking. Nevertheless, it contributes to the research paper since it also addresses factors such as sensation seeking, personality and environmental factors, and cognitive processes as influencing college students to engage in binge drinking. 7. Krock, Becca. Higher drinking age lowers binge drinking for all except college students. 2009. Web 25 Nov 2011 . The article presents important findings from a recent study which revealed that though the national drinking age was set at 21 and has remained so since 1984, the effects on the level of binge drinking among college students have not been significant. However, the article points out that a major decline in the prevalence of binge drinking among teenagers has been noted. The article is relevant to the research paper since it helps the reader to see that altering the drinking age is not enough to curb the issue at hand. The main idea in the article is that since most college students are already 21 years and above, it’s legal for them to drink and the situation is exacerbated by other factors. 8. Nelson, Toben F and Henry Wechsler. Binge Drinking and the American College Student: Whats Five Drink? Psychology of Addictive Behaviours (2001): 15(4), pp. 287-291. The journal article discusses the importance of the clinical five/four measure of binge drinking in evaluating its various consequences. By citing findings about the consequences of binge drinking among college students, the article helps to build the argument presented in this paper. The article notes that there is a huge difference in the severity of binge-drinking consequences between bingers and non-bingers. However, the article does not address the fundamental factors that influence students to engage in binge drinking. 9. Turrisi, Rob, Kimberly A Wiersma and Kelli K Hughes. Binge-Drinking-Related Consequences in College Students: Role of Drinking Beliefs and Mother-Teen Communications. Psychology of Addictive Behaviors (2000): 14(4), 342-355. The information presented in this journal article is highly relevant to the argument since it not only focuses on the false beliefs about alcohol among college students but also the relationship between these beliefs and the consequences. For instance, the article asserts the findings that a direct relationship exists between drinking beliefs and binge-drinking consequences. However, there is no direct relationship between drinking beliefs and consequences when it comes to health matters and physical risk. Overall, the article helps the reader to understand the phenomenon of binge drinking in terms of why students engage in it and the difference in the nature of consequences expected by bingers and the actual consequences. 10. Wechsler, Henry. Binge Drinking on Americas College Campuses. 2009. Web 25 Nov 2011 . In this article, the question of binge drinking is discussed in light of its prevalence which according to the article has remained relatively steady. At the same time, the article notes that more dangerous forms of binge drinking have been on the rise. The far-reaching consequences of binge drinking including alcohol poisoning, poor academic performance, vandalism of property, and physical harm have been highlighted. It helps to underscore the fact that by believing that they are able to control the effects of alcohol, many college students have only predisposed themselves to harm.
