Staples and Cofer Essays

Staples and Cofer Essays Staples and Cofer Paper Staples and Cofer Paper Different Ethnicities Same Problems When Americans meet someone new they are already sticking that person into some sort of category because of their appearance. If someone looks different than Americans are use to, they automatically stick some sort of stereotype to them. Stereotypes are strongly displayed in the media; stereotype can be based of someones color, culture, religion, or sex. In Black men in public spaces by Brent Staples, and in The Myth of the Latin Woman: I Just Met a Girl Named Maria by Judith Ortiz Cofer, the authors talk about stereotypes based on their gender and ethnicity nd the experiences they both encounter because of their ethnicity and gender which have many similarities and differences. Stereotypes can lead to hatred and discrimination against other groups. The problem with stereotyping is it is identifying an individual based on a group a person belongs to, which is not right because each individual is their own person. Stereotypes can be true, and are sometimes false that is why a person should only be Judged by who he/she is, each person is unique in his/her own way. Cofer addresses the stereotypes of Latin women, while Brent Staples points out the social views of African American men by both displaying the stereotypes stuck to them, how the grew up, and encounters with strangers to reveal the similarities and differences they face concerning ethnicity. No matter what ethnicity a person is, it seems as if everyone has to face being Judged based on his/ her ethnicity and getting some kind of stereotype stuck to them. Both Staples and Cofer had to experience being stereotyped, but the way the handle the situation had some similarities. For staples him being an African American man he had to face being Judged by many people and being seen as a criminal. He expresses the feeling of rage because he was always being perceived as a criminal. He describes how many people, no matter what color, reacted when he walks by. He even noticed people lock their car doors as he walks past them, how they cross the street to avoid him, and how some women clutch onto their purses when they walk by him. Mr. Staples understands the fear as well as the real danger that everyone faces everyday however, he still feels alienated about constantly be perceived as a criminal because he was African American and a male. Cofer also goes through life feeling alienated, he notices how she dresses is different from what Americans are used to so she gets singled out from the group and harassed. Growing up Staples had to deal with seeing gangs killing others, people getting locked away, and seeing young friends and family members being buried. Staples 61) While Cofer grew up with strict parents and constantly being told how to act and dress. (Cofer 1 54) Both Cofer and Staples had to deal with having issues to fit it. Staples was a good boy and stood out for that reason he did not participate in the violence and gangs. He knew he did not want to o down the same paths as his friends did which was odd to the people where he group up at. , while Cofer also struggled with not fitting in because she was of different ethnicity and did not dress like the others. They both had went through being Judged growing up because of them being different. Where Staples grew up it people did, and for Cofer it was odd to Americans to see her dress like people in her home country. Although both the essays are dealing with stereotypes among a certain group, Staples encounters with people are very different than Cofers. In Cofers essay, the average Latin woman has to deal with others assuming they are ome kind of sex symbol. There is no fear associated with these Latina women because they do not look intimidating but rather sexy or domestic, they are approached with sexual advances or as if they were all house keepers, maids, or waitresses. In Staples case, he was not only Judged by his intimidating appearance, but also feared by all who came across him. As opposed to Cofer, where people are approaching and harassing her. Staples is seen as a threat and is unapproachable to all who come across his large stature. Staples explains how during several instances while walking around at night he would notice how individuals changed their eactions when they saw him. Staples describes how he would hear the sound of car doors being locked when he would cross a street with cars waiting for the traffic light to change (Staples 60). Staples also explains how tense it would get when he would walk down the street at night with other pedestrians around. Although Staples was everything but a mugger, the people he came across at night from fearing him. Staples was clearly seen as some sort of predator while Cofer was seen as the prey who is constantly approached and being harassed with negative and insulting comments. She was stopped and harassed on many occasions by men singing ffensive songs to her. Staples was nothing like a criminal, what most people assumed he was, he was an educated individual who had an intimidating appearance from his height and dark skin color. Staples is mainly Judged for his larger statue, skin color, and gender which comes off to be considered dangerous to people, while Cofer is also Judge on outer appearance which comes off to be domestic or sexy. Brent Staples, because he is black is perceived as a criminal; Judith Cofer is a Latina and is mistaken for a waitress. Both individuals have numerous examples of when they have been done wrong or discriminated against. When Staples was working as a Chicago Journalist, he was rushing into the office and mistaken by the manager as a burglar or criminal. Cofer went through something similar, when she was about to do her first poetry reading, she had been mistaken for waitress by some older women. Staples and Cofer both had Justified reasons to become upset in these situations and every other situation they have encountered, but instead of becoming upset they decide to do something to correct these misconceptions. Staples always considered himself to be in the wrong in these situations, while Cofer made herself the victim. Staples accepts that people are always going to Judge him because he is a African American male, and he feels he should change himself. As Cofer sees it oppositely, she wants the people who that have these misconceptions to change their ways, not only that she wants them to realize why they should change, and to become more knowledgeable when it comes to different cultures. Both authors are different genders so very different stereotypes apply to them in a different way.. Although Cofer and Staples were both of different ethnicity and gender they both faced many of the same issues of ethnicity, though different scenarios. What was different from Staples and Cofer then other individuals knew these stereotypes were wrong so they both wanted to prove so. Both Authors had a purpose to writing these essays, Staples wanted to reveal to society how peoples perception of the Black Male is affecting them, and Cofers purpose was to address the misconception of the stereotypes of Latin women. In the end, some people may agree with Staples and Cofers purpose and feel stereotypes are wrong, but some will not and may still believe them. Stereotypes are not going away today or anytime soon but it is import that people do not add to them.

Complaints against the Police Essay Example | Topics and Well Written Essays - 3000 words

Complaints against the Police - Essay Example With regard to the budding growth of the concern, the essay also tends to provide a proposal for change policy that leads to increasing policing crimes. In this context, the proposal for a change in policing policy includes a set of effective recommendations that can enable policymakers to reduce different potential issues. Acts of corruption, brutality, and bribery by the people with legislative power have long been witnessed to radically weaken the public faith on the governments. However, the loss of public faith is often regarded to be acute when the legislative acts involved with the police. This is owing to the fact that public, irrespective of their locations relies upon the law enforcement officers in order to uphold legal commandments and ensure adequate protection of the communities and provide assistance when needed. With due regards to various law enforcement reports and analysis, police officers are often considered as the most visible governmental arm for the communities or the citizens. They are often considered to be a yardstick through, which they measure their appropriate authority. The illegal acts performed by the police officers often lead them, to be dishonored not only by himself, but the practices also disgrace the entire legal environment along with the judicial system that he/ she represents (Williams, 2002). Unfortunately, to the growing concern of police officer complaints, there is a number of crucial factors that lead or enable them to commit unethical or illegal practices. In this regard, the organizational culture is often regarded as one of the major aspects that encourage police officers to commit different types of corruption-related acts. Those acts often recognize to be practiced in the form of monetary bribes, misuse of their authorities, or concealing numerous criminal activities.

The Corporate Culture of Zappos Assignment Example | Topics and Well Written Essays - 250 words - 4

The Corporate Culture of Zappos - Assignment Example Considering the importance which Zappos gives the relationship between corporate culture and personal values, it is possible for the company to ask questions that measure the core value of an individual. While measuring an innate quality is difficult, it is easy to get a hint of what an individual perceives a situation (Nelson & Quick 541). This way, through the graduated rating scale, the company’s Human resource team can use the answers given t to evaluate the core values of the person. It is essential to mention that the interview focuses more on personality than technical capabilities. For this reason, the comparison between the core values of the organization and the individual perceptions of the applicant can tell their philosophies. Lack of a formal feedback might bring up issues in the organization. Formalities and bureaucracies have paramount importance as far as communication and consistency are concerned (Nelson & Quick 521). For instance, where an employee does not receive regular feedback, especially in writing, it is likely that any disciplinary action leveled against them will be treated as constructive discharge. As such, formal feedback is essential as it provides inspiration and a basis for employees to improve on their weaknesses as they judge themselves. To avoid such issues, the human resource group at Zappos should always issue a formal feedback. Over time, there are many signs that can be seen in an employee that fits into the corporate culture of Zappos. One of the signs of a character that fits the culture is the subordination of personal interest to organizational interest. Additionally, such an employee will be motivated and satisfied with their job. On the contrary, an employee that does not match the corporate culture of Zappos will be less concerned about organizational interests and will usually be a poor performer whose job is characterized by non-punctuality, and less formality.

Citric Acid to Remove Stains | Experiment

Citric Acid to Remove Stains | Experiment BACKGROUND AND PURPOSE: Knowledge about natural bleaches to remove stain may be useful in our daily life. Natural bleaches can be found in various types of fruits juice and many more. This green bleaches are more friendly to environment and cheaper than commercial product. Citric acid is one of bleaching agent that can be found in the citrus fruits such as lemon. This paper will discuss on the process of removing stains by citric acid in different type of fruit juices. The investigation was focused on How does the type of citrus fruits used affect the rate of reaction of stain removable? Since stains have different types, the effectiveness of citric acid on two types of stains (synthetic and vegetable based stain) had been discussed more in this investigation. MATERIALS AND METHODS: The experiment was conducted with different type of fruits; lemon, lime, navel orange and pineapple. The time taken for the different type of stain to be removed by different type of fruits had been recorded and be analyzed to identify the most best used as natural bleaches. RESULTS: Even though the lemon juice is more popularly known as natural bleach but based on the experiment, the best used citrus fruit as bleaching agent is lime and the citric acid is most effective used to remove vegetable based stain.

Chemically, bleaches will breaks the stain molecules into smaller molecule that easily be removed. D.Noemia Souza (2008) stated that bleaches are chemical that capable to whitening the fabrics and removing stains by destroying colouring matter. There are two types of reaction that involve in bleaching. Commonly bleaching process involves in oxidation processes such as hydrogen peroxide and some involve the reduction processes such as sodium chlorite. However in bleaching processes, the oxidation and reduction also can occur simultaneously. Bleaching process for stains most effective when both an oxidative and a reductive bleaching steps worked together and this referred as full bleaching (J.M. Cardamone W.N. Marker, 1995) There are various types of bleaches, and each type of bleach is specifically used for certain type of fabrics. The fabrics are very specific and if use d with wrong bleach, the fabric will wear out. Concentration, pH, time and temperature are the various conditions which are affect the action of bleach on fabrics. Chemistry of Bleach Hydrogen peroxide is the most prominent bleach and usually used in commercial bleaches. However, according to D.Noemia Souza (2008), the strongest bleach is sodium hypochlorite while the weakest is sodium chlorate and the hydrogen peroxide is milder. Sodium hypochlorite(Chlorine-containing oxidants) Usually, the sodium hypochlorite will contain 15-18% of chlorine (D.Noemia Souza, 2008). Under certain condition, the solution will decompose into sodium chlorite (eq1) which then reacts with hypochlorite and produce the sodium chlorate (eq2). The sodium hypochlorite will undergoes further reaction to release oxygen (eq3). Thus it is classified as chlorine bleach 2NaOCl NaCl + NaClO2 (1) NaOCl +NaClO2 NaCl+NaClO3. (2) Overall equation: 3 NaOCl 2NaCl+NaClO3 (3) 2NaOCl 2NaCl+O2 (4) Hydrogen peroxide(preoxygen bleach) Hydrogen peroxide bleaching will dissociates into H+ and per hydroxyl ions HOO-(eq1).The per hydroxyl ions is the active bleaching agent. Under alkaline conditions it will release oxygen (eq2).Cotton would damage under this conditions as the bleaching effect is slow and the bleaching rate is fast. The activator and stabilizers are added to control this condition (J.M. Cardamone W.N. Marker, 1995). H2O2 HO2- + H+.. (1) 2H2O2 2H2O +O2 (2) Hydrogen peroxide is a universal bleaching and D.Noemia Souza (2008) said it is the only oxidizing bleach that can be safely used on protein. Mechanism of Bleaching Based on ProcterGamble (2005) the process of bleaching is divided into two, which are; Breaking up the stain The stain consist of molecule chains covering the fabrics The bleach molecule will break the stains into smaller pieces After that process, bleach molecule will disappear The stain is now broken into smaller pieces which can be easily removed by the surfactant Decolorizing the stains The stains color has its origin in the double-bond connections Then, the bleach will break up the bond and convert it into single bond, eliminating its ability to absorb visible light. After that, the bleach molecules will disappear. Once the double-bond connections are broken up, the stains isnt visible anymore. Citric Acid as Natural Bleach Citric acid is weak organic acid and one of the acids found in citrus fruits such as lime and lemon. It popularly used in food industrial as perservative. It also can act as natural bleaching agent and an antioxidant. So it is useful in our daily life to remove stain or dirt from fabric and bleach the spot. Citric acid exist in many type of vegetables and fruits but more concentrated in lime and juice where the dry weight of citric acid in fruit comprimise as much as 8 percent (sciencedaily.com).The concentration of cotric acid in fruits range from 0.005 mol/L for oranges to 0.30 mol/L in lemons and limes (Wiki.Org) Rationale of the Study Nowadays, most of people prefer to use biodegradable product or green product. Especially in current downturn economy, many people change to less expensive products. Using citrus fruits as an alternative ways to remove stain is the good choice. The question that arises here is what the significance of knowing which of the citrus fruits is best used in removing stains? Significance of the Study Sodium hypochlorite (chlorine bleach) and hydrogen peroxide (oxygen bleach) are extremely popular in the market to whiten the fabrics and in stain removable. However, there are some disadvantages using oxygen and chlorine bleaches. Most of them are hazardous if ingested or inhaled and should be used with care. Lindsay Evans (2009) also explained the chlorine can cause negative health effects. Besides, they are costly and give a bad impact to our environment especially rivers and lakes ecosystem. Chlorine that flowing into rivers or lakes will combine with other chemical to form a stable compound where it will remain unchanged in groundwater for many years (Wisconsin, 2010). On the other hand, citric acid best uses as natural bleaches because it does less harm to ecology of rivers and lake. Limitation of the study All of the experiment will conduct in the Mara College Serembans laboratory. Most of the material such as citrus fruits; lemon, lime, navel oranges and pineapple and table salt are obtained from Carrefour Cheras in Cheras, Selangor, Malaysia. So, all of the fruits are not in the same level of freshness due to different condition during storage that may affect the freshness of the fruits. Besides that, the fruits might not come from same tree and this will affect the concentration of acid in the fruits. Research Question The focus of study is to investigate the ability of citrus fruits as natural bleach to remove stain from fabric. The main objective of this study is to identify which of the citrus fruits; lime, lemon, pineapple, and navel oranges is best used as bleaching agent. So the research question of the study is How does the different type of citrus fruit used; lime, lemon, pineapple, and navel oranges affect the rate of reaction of stain removable? The study uses 4 different types of citrus fruits which are lime, lemon, pineapple, and navel oranges that will extract into juice and add with table salt (sodium chloride). Hypothesis The research question of the study is How does the type of citrus fruits used affect the rate of reaction of stain removable? The rate of reaction of stain removable is the highest at the most acidic solution. So the hypothesis is the most acidic fruit in this case is lime or lemon as both contains high concentration of citric acid. Variables Independent Variable There are two independent variables in this experiment as the experiment is divided into several parts. The first independent variable is the different types of citrus fruit juices; lemon, navel orange, lime and pineapple. While the second independent variable is the different type of stains where synthetic stain (syrup) and vegetable stain(tomatoes) are used throughout the experiment. Dependent Variable Rate of reaction to remove the stain from fabric will be the dependent variable. The time taken will be record by stopwatch for the stain to decolorize. Then by using the graph the gradient is determine which represent the rate of reaction. Fixed Variable The fixed variables are type of cloth (cotton), volume of juice (5oml), temperature (100ËÅ ¡c) and volume (100ml) of water bath and quantity of sodium hydroxide (3 teaspoon). All of this material will be use in same quantity throughout of the experiment. Apparatus and Materials Material Quantity Fruit juices (lemon, lime, navel oranges, and pineapples) 50 cm3 100 ËÅ ¡c of water bath 100 cm3 Phenolphthalein Distilled water 40 ml Table salt 1.0M of NaOH solution Dried KHP 3 teaspoon 10 cm3 1.0 g 4.0 Procedure and Analysis Preparation of an approximately 0.1 M Sodium Hydroxide Solution followed by the Standardization of the Sodium Hydroxide Before testing the concentration of citric acid, the standard sodium hydroxide solution needs to be prepared. In order to prepare 0.1 M of NaOH, 9.0 cm3 of 1.0M sodium hydroxide solution was diluted with 100.00cm3 of distilled water. Then the sodium hydroxide solution was standardizing to determine its concentration by titrated it with KHP. This acid base reaction is shown in Equation 1(M.L.Gillette, 1999); KHP(aq) + NaOH (aq) NaKP(aq) + H2O(l)(eq1) Two portion of 0.5g of dried potassium hydrogen phthalate (KHP) was weighed and dissolved with 50ml distilled water in conical flask. The Phenolphthalein solution was added for 2-3 drops into KHP solution to indicate the end point of titration. Phenolphthalein was used because the pH range of product is 8-10 .The sodium hydroxide was titrated with KHP solution until pale pink color was produced. The volume of NaOH solution added was recorded. Data Collection for Standardization of NaOH Number of trials 1sttrial 2ndtrial Initial Burette reading/cm3 ( ±0.05cm3) 0.00 0.00 Final Burette reading/cm3 ( ±0.05cm3) 23.50 25.40 Volume NaOH solution added/cm3 ( ±0.05cm3) 23.50 25.40 Observation After few minutes, the clear solution turned into pale pink before disappeared. After few minutes, the clear solution turned into pale pink before disappeared. Table 4.0 Data Analysis The purpose to standardize sodium hydroxide solution against potassium hydrogen phthalate is to determine the exact value of sodium hydroxide concentration. By titrate the 0.1M of sodium hydroxide solution against KHP solution the results collected are more accurate. The concentration of sodium hydroxide was found to be 0.1002M Calculation for determining the concentration of the sodium hydroxide; KHP (aq) + NaOH (aq) NaKP(aq) + H2O To calculate the number of mole of KHP Number of mole= mass/molar mass = 0.5g KHP/ 204.2 = 2.449ÃÆ'-10-3mol KHP To calculate the number of mole of NaOH required to neutralized KHP solution No. of moles of NaOH = No. of moles of KHP = 2.449ÃÆ'-10-3mol NaOH To calculate molarity of NaOH solution Concentration of NaOH = (number of moles/ volume of NaOH)ÃÆ'-1000 = (2.449ÃÆ'-10-3/ 24.45) ÃÆ'-1000 = 0.1002M Percentage uncertainty of the concentration of the 0.1M of sodium hydroxide % Uncertainty of Concentration of 0.1M NaOH = Volume(H2O) + Volume(NaOH)+ Concentration of NaOH(1.0M) % Uncertainty of VH2o = 0.04/100.00 ÃÆ'- 100 = 0.040% % Uncertainty of VNaOH = 0.05/9 ÃÆ'- 100 = 0.600% % Uncertainty of CNaOH = 0.040+ 0.600 =0.64% Extraction of juices from citrus fruits. The lemon was cut into small pieces and blend with blender. The juice released was putted into the beaker and labeled with A. First step was repeated again until half of the beaker filled. Then, the extracted juice was filtered through muslin cloth. The whole procedure were used again with another type of fruits, lime, navel orange and pineapple and labeled with; Beaker Type of juice A Lemon B Lime C Navel orange D Pineapple Citric Acid Determination The reason of citric acid determination is because to know the exact value of citric acid in juices for data analysis. This process is carried out by adding NaOH into the fruit juices. The approximately 10 mL of lime juice was prepared by using pipette and transferred into a conical flask. Then, the lime juice was diluted with 20ml of distilled water and three drops of phenolphthalein was added into solution. The solution with 0.1M sodium hydroxide (NaOH) was added from burette to the juice sample while swirling the mixture until the reaction mixture turned into faint pink color. The end point was reached when the pink color persists for thirty seconds. The volume of NaOH added was recorded. The processes were repeated again to increase the accuracy. Then, the procedure was repeated with different type of juice; lemon, orange and pineapple. By using the formula, the molarity of citric acid in the fruit juice was calculated.

Data Analysis- calculation for determining the citric acid concentration through sodium hydroxide added. The citric fruits consist of citric acid. Citric acid contains carboxyl acid group and reacts with hydroxide ion as indicate in equation 2 (Dr. Ewa Thomas, 2007). The sodium hydroxide will ionize to form sodium ions and hydroxide ions (eq 1). NaOH (s) Na+ (aq) + OH (aq) (eq 1) C3H5O (COOH)3 (aq) + 3 OH- (aq) C3H5O(COO)33- (aq) + 3 H2O (l) (eq 2) The purpose of this experiment is to determine the concentration of citric acid on the citrus fruit by titrating the citrus juice with standard sodium hydroxide solution. The concentration of citric acid can be calculated by measuring the volume of sodium hydroxide used (eq 3). Molarity,M= (eq 3) M1V1 = M2V2 (eq 4) Based on the equation, the molarity of the OH- ions equal with sodium hydroxide as the molecular ratio is 1:1. So, the molarity of hydroxide ions can be known. By using equation 4, the concentration of citric acid can be determined. Calculating the concentration of citric acid By using the data given above, I had calculated the concentration of citric acid in citrus juices. The citric acid C6H8O7 is a triple basic acid that consists of three carboxylic acids and react with one hydroxide ion ,eq 1(Ewa Peter Thomas M Moffet, 2007). In this experiment, I assumed that the citric acid is sole acid found in the citrus fruits. C3H5O(COOH)3 (aq) + 3 OH- (aq) C3H5O(COO)3 (aq) + 3 H2O (l).(eq 1) However, according to experiment conducted by Law.C Solak.E(2009) the citric acid does not always have the 3 carboxylic acid. So, in this experiment I will assume that the citric acids only have 1 carboxylic acids but its less accurate. The following reaction takes place in the titration; C6H8O7 + OH- à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ H2O + C6H7O7- (eq 2) Based on the equation(eq 2), the molarity of the OH- ions equal with C6H8O7 as the molecular ratio is 1:1. By using equation below, the concentration of citric acid can be determined. M1V1 = M2V2 where : m1 = molarity of Sodium hydroxide, NaOH v1 = volume of Sodium hydroxide Solution, NaOH m2 = molarity of dilute citric acids, C6H8O7 v2 = volume of dilute citric acids Solution, C6H8O7 Example of calculation: By Using the volume of NaOH use to titrate lemon juice 0.1M NaOH ÃÆ'- 23.98 ml = M2 ÃÆ'- 10 ml 0f C6H8O7 2.298 mmol OH- = M2 ÃÆ'- 10 ml C6H8O7 M2 = = 0.2398 mole/L C6H8O7 (The calculations showed above are applied to all other experiment, table 5.5) Calculating Uncertainties Percentage uncertainty of Concentration = [(Άn / n) + (ΆVolume / Volume)] x 100% Example; Percentage uncertainty of concentration for Lemon = = 6% Absolute uncertainty of concentration = Percentage uncertainty x Concentration / 100% Example for Lemon = 6% ÃÆ'-0.24/100% = 0.014 moldm-3 0.01 moldm- Data Presentation Type of juice Average NaOH used( ±0.1)mL Concentration of citric acid (mol/L) Lemon 23.98 0.2398 Lime 10.78 0.1078 Navel Oranges 5.35 0.0535 Pineapples 2.95 0.0295 Table 4.6 Procedure for process of stain removable The white cloth cotton was cut into3cmÃÆ'-3cm size for 20 pieces and each pieces of cloth were stained with syrup solution. Then the stained clothes were dried for about 1 hour. 20 cm3 of lime juice was prepared and the initial pH of juice was recorded by using pH meter. For the first trial, a stained cloth was held under the running water and was soaked in the lime solution for more than 30 minutes. After that, the stained cloth was put into100ËÅ ¡c hot water bath and the time taken for the stained decolorize was recorded. However, the stained took longer time to decolorize where the average of time taken cannot be recorded. So I used another method by adding 3 teaspoon of table salt (sodium chloride) into lime juice. The pH value of juice was recorded. The stained cloth was rubbed with salt before soaked into the solution for an hour. Then, the stained cloth was putted into 100 °C hot water bath and the time taken for the stained decolorized was recorded. In order to identi fy the best fruit best use to remove the stain, the whole step was repeated again with another type of fruits; lemon, navel orange, and pineapple. The results from different type of fruits were compared. Besides that, I also used the different type of stain to test which one is more effective been bleached by citric acid. In this experiment I used vegetable based stain which is tomato stain. The first method is used; without adding the table salt (sodium chloride) and the result was recorded and be compared with synthetic stain (syrup). Data Collection for Removable of stain Qualitative data For synthetic stain: The pinks colour of stain turns into colourless. Fabrics become white Fabric cloths smell fruity. The juices become more slippery when added with sodium chloride. For organic stain The red colour of tomatoes decolorize The fabric colour turn into redish The fabric turns white after held under running water. Data Analysis According to the data collected, the different type of fruits and different type of stain will affect the time taken for the stain to decolorize. For the syrup stain, there must be influenced by sodium chloride (cooking salt) as it is hard to remove by citric acid alone. Adding the cooking salt involved the osmosis concept where the solution will become more saturated, the water will moving from the cloth to the salt and taking the stain together (T. Lister J. Renshaw, 2000). When the cooking salt is added into the juice, the pH of juices drop and become more acidic. However, chemically the cooking salt does not affect the acidity of citric acid. The drop in pH value may be due the presence of water in the juices which react with the salt and release the hydrogen ions which might cause this to be happened. The reason putting stained cloth into the hot water is to increase the reaction by increase the movement of particle and reduce the time taken to remove the stain (Kenneth M.S, 194 2). The highest rate of reaction (Table 4.9) calculated is lime juice and the lowest rate of reaction is pineapple juice. The reaction for both juices can be related with its pH and concentration. In term of concentration of citric acid, the higher the concentration of citric acid will increase the acidity of juice and the time taken for stain removable will become faster. However, this might not be true for lemon juices. Even though, it has highest citric acid concentration but the time taken for stain removable is not the fastest. This probably because of error and limitation occurred and will be discussed more in other section. Meanwhile, graph 4.4 shows the rate of reaction of stain removable for both type of stain by using Microsoft Excel. It is show that the rate of reaction for removable stain in tomatoes stain is 0.154, higher than syrup stain. This is might be because the syrup stain is more thick and viscous. While the vegetable based stained (tomatoes) is easier to remove because it is organic in nature and more soluble in lemon juice. 8.0: Conclusion and Evaluation Conclusion The experiments showed that the type of citrus fruits used does affect the average time taken to remove the stain. The hypothesis that rate of reaction would be highest in the most acidic fruit (lime) which consist high concentration of citric acid, is also supported based on the data collected. The pH of lime is 2.2; most acidic among the others citrus fruits. The main objective of this essay is to identify which of the type of citrus fruits; lime, lemon, pineapple, and navel oranges are best used as bleaching agent. As mention above, the type of citrus fruit does affect the rate of reaction to remove the stain. However, it also depends on the type of stain. Test on fabric with synthetic stain without adding sodium chloride (salt) required a long time where the average time taken cannot be collected. Meanwhile, citrus fruits are best used on fabric with vegetable based stain as there in no influence with sodium chloride. It can be said that the sodium chloride act as catalyst and ma king the removable of stain easier. In addition, the time taken to remove the stain for vegetable based stain is fastest compare than synthetic stain. The hot temperature was used in the experiment to speed up the reaction. Thus it can be concluded that, the lime is the best used as bleaching agent but with certain condition; type of stain and temperature. Evaluation Some error and limitation occurring during the experiment which causes the result collected imprecise. The limitation and errors in these experiments can be divided into several parts. For the first part is problem in procedure A. Initially, the sodium hydroxide prepared had been assumed exactly 1.00M. However, to test the accuracy of the concentration, the sodium hydroxide had been standardized using KHP solution. After calculating the concentration of the sodium hydroxide, the concentration of sodium hydroxide is approximately 0.1M with 0.2% of percentage error. There is a limitation occur when calculating the concentration of citric acid by titrate it with sodium hydroxide solution. One problem is the citrus fruits contain several type of acid. So, in the experiment the citric acid had been assumed as sole acid in citrus fruits and be supported by Dr. Ewa Thomas. As a result, the amounts of citric acid concentrations calculated are inaccurate and larger than theoretical value. The citric acid should been standardized to know the exact concentration, where it reduce the uncertainties. Besides that, some common mistake occurred in the experiment such as improper position of burette and parallax error in taking the measurement. To overcome this, there is no other solution except reduce the parallax error by positioning the eyes straight to the scale reading needed and position the apparatus used at the smooth surface. Moreover, it was hard to determine that the colour of the solution turned to faint pink colour because if the titration of NaOH was titrated without care the solution will become too red. So the result of the first faint pink colour come out should be observed and detected properly so it needs a particular partner in doing that job. Based on data collected, there is error between the concentration of citric acid and pH value for lemon juices where supposedly the pH of lemon juice should be most acidic as it has highest citric acid concentration. The problem may arise in determining the citric acid concentration where the value of citric acid calculated in lemon juice was incorrect. Because of the lemon used are in different freshness (as mention earlier in limitation of study), it might affect the result. So, the same lemon must be use throughout the experiment. In the last part (procedure D), one of the error occurs is during taking the average time taken to remove the stain from fabric. When the stained fabric is place into hot water, it is difficult to identify whether the cloth decolorize or not because it is possible for fabric to turn into white without be rub. To improve this, the experiment must be repeated for several times to increase the accuracy. There is also a limitation where the removable of stain cannot be seen clearly when test conducted with coffee at first. So, to overcome this problem, the stain was changed into syrup which the red colour can be seen clearly. However the problem had comes when there is change in pH value of fruit juice after adding with NaCl due to presence f water. This might be because limitation that occurred during extraction of juice. So, it is necessary to ensure all the equipment to rinse and dry first before conducting any experiment. Recommendation for further research More work could be done on the use of sodium chloride (cooking salt) in removing stain; is it effective used and how it will increase the effectiveness of citric acid in removing stain? The other use of citric acid beside remove stain should be investigated as if citric has potential in other cleaning process. Besides that, while the experiment was done by using citrus fruits as natural bleaching agent other natural bleaching agent should be considered. Investigation on the effectiveness of citric acid by comparing it with the commercial bleaches and color safer bleaches has applications in our daily life. CdS Quantum dots: Synthesis and Optical Properties CdS Quantum dots: Synthesis and Optical Properties CdS Quantum dots: Synthesis and Optical Properties Characterization for Solar Cell Raimy Roy Abstract— In this work CdS quantum dots were synthesized using Successive Ionic Layer Adsorption and Reaction (SILAR) method. Then a study of the morphology and optical property were made for the application of solar cell. The structural characterization were made by XRD while the optical characterization where done by UV-vis-NIR spectroscopy techniques. Index Terms—Quantum dots, SILAR I. INTRODUCTION Quantum dot sensitized solar cell is an emerging field of photovoltaic in which the absorbing material is a quantum dot. The advantage of using such solar cell is size tunability and increased surface to volume ratio. In a quantum dot based solar cell the active layer consist of the quantum dot and the scattering layer is formed by the TiO2 layer. The mesoscopic TiO2 when deposited with CdS quantum dot act as an energy harvester and convert the incident photon to electricity. In this work, a model of the photoanode for the solar cell was made with mesoscopic TiO2 layer as scattering layer and quantum dots as absorbing layer. Here instead of ITO a glass slide was used. [1] To synthesize a quantum dot various techniques are used. Among them Successive Ionic Adsorption and Reaction (SILAR) method is a cost effective and is used to prepare quantum dot. In a SILAR method the time of reaction or the number of cycles can be controlled. Depending on which the size of the quantum dot varies. Another advantage of this technique is that it can be prepared at room temperature. Also this method provides a close contact between the quantum dots and the oxide layer, so it is an attractive method for the preparation of electrodes in a solar cell. [1] Cadmium sulfide (CdS) quantum dot is a direct band gap semiconductor. It is a II-VI compound semiconductor that is used for many optoelectronic devices such as solar cell, laser diodes and photoconductors. It is an inorganic semiconductor which has several advantages over conventional dyes. These advantages are band gap tunability, large extinction coefficient (this means that the dark current can be reduced and the overall efficiency can be improved) and multiple electron generation by utilizing hot electrons. [2] II. EXPERIMENTAL SETUP Chemicals Required Titanium dioxide powder (SD Fine-Chem Limited, purity 60%), 2M nitric acid, 0.05M cadmium nitrate, ethanol, 0.05M sodium sulfide hydrate (Sigma Aldrich, assay=60%), methanol. Preparation of TiO2 layer on glass slide A paste of titania (TiO2) was prepared from TiO2 powder and nitric acid. The chemicals were added in 2:1 proportion. A thin layer of titania paste was coated on the glass slide using a technique called doctor blade method [3]. In this method, either a glass rod or a microscope slide is used. We have used a microscope slide of thickness 1.45mm to coat the paste. A glass slide of dimension 2cm X 1cm was cut and cleaned. With the help of an adhesive tape, the glass slide is positioned firmly on the work bench. Another advantage of using such tape is that we could define an area to coat the paste and to deposit the quantum dot. Now place the paste on one side of the glass slide, positioning the microscope slide in 45à ¯Ã¢â‚¬Å¡Ã‚ ° spread the paste across the glass slide. Repeat the operation till a reasonably homogeneous layer is formed. After coating heat the paste to 80à ¯Ã¢â‚¬Å¡Ã‚ °C followed by annealing at 450à ¯Ã¢â‚¬Å¡Ã‚ °C for 30 min. After sintering the paste is white in color . This provides a better surface for adsorption of the CdS quantum dots since sintering makes the mesoporous films to a continuous network. Deposition of CdS Quantum Dots Successive Ionic-Adsorption and Reaction method is commonly used to deposit metal sulphide onto a nanostructured film. CdS quantum dot was deposited onto titania using this method as described in [4]. The first precursor solution used is 0.05M cadmium nitrate (Cd(NO3)2) and the second precursor solution is 0.05M sodium sulphide (Na2S). The bare TiO2 paste is dipped onto the first precursor solution for one minute. The Cd2+ ions have been deposited onto the TiO2 surface. This is then rinsed in an ethanolic solution for one minute and dried under room temperature. It is then dipped in the anionic precursor for one minute and then rinsed in methanolic solution for one minute and allowed to dry at room temperature. This completes one deposition cycle of SILAR. In this work we have performed four deposition cycles of SILAR. III. RESULT AND DISCUSSION The CdS quantum dot was deposited on to the surface of TiO2. An obvious color change was observed during the deposition cycle which is shown in Fig.1. The color change was pale yellow to golden yellow. The characterization was done using XRD and UV-vis spectroscopy techniques. Fig 1: Photograph of glass slides with CdS coating with increasing SILAR cycles XRD Characterization Fig 2. shows the obtained XRD pattern for TiO2 (Fig.2a), TiO2/ CdS (Fig 2b.) . From the peak obtained, we confirm that CdS quantum dot was deposited onto the film. Since the peaks at 44.1à ¯Ã¢â‚¬Å¡Ã‚ °, 51.9à ¯Ã¢â‚¬Å¡Ã‚ °, 64.3à ¯Ã¢â‚¬Å¡Ã‚ °, 70.4à ¯Ã¢â‚¬Å¡Ã‚ ° and 72.9à ¯Ã¢â‚¬Å¡Ã‚ ° coincides with the intensity pattern as defined by the JCPDS 10-0454 for the CdS QD. The corresponding miller indices are (220), (311), (400), (331) and (420). From this we conclude that CdS QD was deposited. It belongs to the cubic crystal system and the mineral name is hawleyite. For TiO2 the XRD pattern exactly matches with JCPDS 21-1272. It belongs to tetragonal crystal system and its mineral name is anatase. Fig.2 : XRD pattern (a) TiO2 (b) TiO2/CdS Size Characterization The size characterization was done by non-contact mode AFM (Atomic Force Microscopy). The size of the CdS quantum dot was found to be 25.83nm. the thickness of the deposited layer was calculated to be 29.65nm. Fig 3. Fig 3 : AFM non-contact mode characterization of CdS quantum dot UV-vis Characterization The optical property was characterized using Jasco Spectrophotometer V670. The absorption spectrum is shown in Fig 4. The absorption spectrum for the TiO2 and CdS/TiO2 is shown in Fig 4a. and TiO2/CdS alone is shown in Fig.4b. The absorption peak for CdS is as reported by Antonio et.al [4]. From the absorption spectrum we could observe a shift in the peak indicating CdS QD is being deposited. The absorption peak was observed in the range of 386nm-484nm. For TiO2 the absorption peak was observed at 341nm. In Fig 4b. the inset is the absorption spectrum that was reported in [5] Fig 4: Absorption spectrum of (a) TiO2 and TiO2/CdS (b) TiO2/CdS Fig 5: UV-Vis absorption spectra showing increase (~49 %) in absorption due to CdS Figure 5. depicts the percentage increase in the absorption peak of CdS with respect to TiO2. It was calculated to be a 49.08% increase in the absorption peak. Determination of Optical Band gap The DRS (Diffuse Reflectance Spectroscopy) characterization was done to obtain the optical band gap. The optical band gap was calculated by plotting the Tauc plot . It is the plot between energy and absorbance. The optical band gap can be determined by Tauc relation Where à ¯Ã‚ Ã‚ ¡ is the absorption coefficient in cm-1, hà ¯Ã‚ Ã‚ ® is the photon energy in eV and A is a constant. The value of n is given as follows n =  ½ for direct allowed transition n = 2 for indirect allowed transition The Tauc plot for TiO2 and TiO2/CdS is shown in Fig 6. TiO2 is an indirect band gap material whereas CdS is a direct band gap semiconductor. The bandgap value of CdS in bulk is given as 2.42eV [5]. From the experiment we calculated the optical band gap to be 2.38eV. Also the absorbance value of the CdS QD is blue shifted. Using the equation The value of the peak was calculated to be 519.16nm which is within the absorption region. Fig 6. Tauc plot of (a) TiO2 (b)TiO2/CdS IV. CONCLUSION In this work CdS quantum dot have been synthesized using SILAR method. Its structural characterization was done that confirmed the deposition of the CdS quantum dot on to TiO2 paste. The optical property was characterized and analysed using UV-vis-NIR spectroscopy. The optical band gap was calculated to be 2.38 eV. The size of the quantum dot deposited was calculated to be in nanometer.

The wind was blowing, the trees swaying from side to side. It was time for me to conquer my fears. Although I did not know it, I was about to begin an adventure that would push my companions and I to our limits. The day had just begun. My alarm clock was ringing and the birds were chirping. It seemed like it was going to be a fantastic day.The sun was out; there was not a breath of wind. I fled from my bed so I would not miss a moment of the beautiful day Mother Nature had been kind enough to share. I devoured my breakfast like it was my last and turned on the television. It was a magnificent day but little did I know that on this day I would take part in an event that would push me to my limits. And that’s when I noticed the branches of the trees starting to sway rhythm with the wi nd. I thought to myself, surely this cannot be. In an instant there were clouds on the horizon. I did not believe my eyes.The weather had changed instantaneously changed. It was now a cold, miserable and windy day. Then I saw her standing in the distance. She told me she was going to take me to a place of adventure, somewhere where I could overcome my fears and attempt something that only few had dared. She took me to this place. It was not scary, not intimidating. In fact it was extremely inviting. There were people eating foods at the gorgeous restaurants. While admiring this concrete jungle known as the Moses Madibha Stadium I realised I was no longer afraid. I was wrong.I was going to be going to be going face to face with my greatest fear. I was going to be jumping off this jungle. Papers were signed, my harness firmly secured around my waist. It was time to begin my voyage.

The gigantic white structure surrounded me. It was as if I was on a pathway to happiness. After what seemed like an eternity I had arrived at my destination.It was my time to shine. The spotlight was firmly placed on me. Pure adrenaline rush! Pure energy! It was now or never! This was the opportunity I had been waiting for! It was time for action. Then it happened. I jumped. I felt my stomach disappear my toes went numb, the wind was rushing through. I then opened my eyes. To my delight it was all over. My heart was pounding, my blood gushing through my veins. There I was dangling in mid-air. I had conquered my fear. I felt like I was in a scene in a movie. All I could think was that it had been an amazing day. Word count: 511

Ethics and Moral Theory Essay

The words â€Å"moral† and â€Å"ethics† (and cognates) are often used interchangeably. However, it is useful to make the following distinction: Morality is the system through which we determine right and wrong conduct — i.e., the guide to good or right conduct. Ethics is the philosophical study of Morality. What, then, is a moral theory? A theory is a structured set of statements used to explain (or predict) a set of facts or concepts.à  A moral theory, then, explains why a certain action is wrong — or why we ought to act in certain ways.à Ãƒ  In short, it is a theory of how we determine right and wrong conduct.à  Also, moral theories provide the framework upon which we think and discuss in a reasoned way, and so evaluate, specific moral issues. Seen in this light, it becomes clear that we cannot draw a sharp divide between moral theory and applied ethics (e.g., medical or business ethics). For instance, in order to critically evaluate the moral issue of affirmative action, we must not attempt to evaluate what actions or policies are right (or wrong) independent of what we take to determine right and wrong conduct. You will see, as we proceed, that we do not do ethics without at least some moral theory.à  When evaluating the merits of some decision regarding a case, we will always (or at least ought to always) find ourselves thinking about how right and wrong is determined in general, and then apply that to the case at hand.à  Note, though, that sound moral thinking does not simply involve going one way — from theory to applied issue.à  Sometimes a case may suggest that we need to change or adjust our thinking about what moral theory we think is the best, or perhaps it might lead us to think that a preferred theory needs modification. Another important distinction: Are moral theories descriptive or prescriptive ? In presenting a moral theory, are we merely describing how people, in their everyday ‘doings’ and ‘thinkings,’ form a judgement about what is right and wrong, or are we prescribing how people ought to make these judgements? Most take moral theories to be prescriptive. The descriptive accounts of what people do is left to sociologists and anthropologists.à  Philosophers, then, when they study morality, want to know what is the proper way of determining right and wrong. There have been many different proposals.à  Here is a brief summary. Theories of Morality (1) Moral Subjectivism Right and wrong is determined by what you — the subject — just happens to think (or ‘feel’) is right or wrong. In its common form, Moral Subjectivism amounts to the denial of moral principles of any significant kind, and the possibility of moral criticism and argumentation.à  In essence, ‘right’ and ‘wrong’ lose their meaning because so long as someone thinks or feels that some action is ‘right’, there are no grounds for criticism.à  If you are a moral subjectivist, you cannot object to anyone’s behaviour (assuming people are in fact acting in accordance with what they think or feel is right).à  This shows the key flaw in moral subjectivism — probably nearly everyone thinks that it is legitimate to object, on moral grounds, to at least some peoples’ actions.à  That is, it is possible to disagree about moral issues. à  (2) Cultural Relativism Right and wrong is determined by the particular set of principles or rules the relevant culture just happens to hold at the time. Cultural Relativism is closely linked to Moral Subjectivism.à  It implies that we cannot criticize the actions of those in cultures other than our own.à  And again, it amounts to the denial of universal moral principles.à  Also, it implies that a culture cannot be mistaken about what is right and wrong (which seems not to be true), and so it denies the possibility of moral advancement (which also seems not to be true). à  (3) Ethical Egoism Right and wrong is determined by what is in your self-interest.à  Or, it is immoral to act contrary to your self-interest. Ethical Egoism is usually based upon Psychological Egoism — that we, by nature, act selfishly.à  Ethical egoism does not imply hedonism or that we ought to aim for at least some ‘higher’ goods (e.g., wisdom, political success), but rather that we will (ideally) act so as to maximize our self interest.à  This may require that we forgo some immediate pleasures for the sake of achieving some long term goals.à  Also, ethical egoism does not exclude helping others.à  However, egoists will help others only if this will further their own interests.à  An ethical egoist will claim that the altruist helps others only because they want to (perhaps because they derive pleasure out of helping others) or because they think there will be some personal advantage in doing so.à  That is, they deny the possibility of genuine altruism (because they think we are all by nature selfish).à  This leads us to the key implausibility of Ethical Egoism — that the person who helps others at the expense of their self-interest is actually acting immorally.à  Many think that the ethical egoist has misunderstood the concept of morality — i.e., morality is the system of practical reasoning through which we are guided to constrain our self-interest, not further it.à  Also, thatà  genuine altruism is indeed possible, and relatively commonly exhibited. à  (4) Divine Command Theory Many claim that there is a necessary connection between morality and religion, such that, without religion (in particular, without God or gods) there is no morality, i.e., no right and wrong behaviour.à  Although there are related claims that religion is necessary to motivate and guide people to behave in morally good way, most take the claim of the necessary connection between morality and religion to mean that right and wrong come from the commands of God (or the gods).à  This view of morality is known as Divine Command Theory.à  The upshot is that an action is right — or obligatory — if God command we do it, wrong if God commands we refrain from doing it, and morally permissible if God does not command that it not be done. Divine Command Theory is widely held to have several serious flaws.à  First, it presupposes that God or gods exist.à  Second, even if we assume that God does exist, it presupposes that we can know what God commandsà  But even if we accept theism, it looks like even theists should reject the theory.à  Plato raised the relevant objection 2500 years ago.à  He asked: Is something right (or wrong) because the gods command it, or do the gods command it because it is right? If the latter, then right and wrong are independent of the gods’ commands — Divine Command Theory is false.à  If the former, then right and wrong are just a matter of the arbitrary will of the gods (i.e., they might have willed some other, contradictory commands). Most think that right and wrong are not arbitrary — that is, some action is wrong, say, for a reason.à  Moreover, that if God commands us not to do an action, He does so because of this reason, not simply because He arbitrarily commands it.à  What makes the action wrong, then, is not God’s commanding it, but the reason.à  Divine Command Theory is false again. à  (5) Virtue Ethics Right and wrong are characterized in terms of acting in accordance with the traditional virtues — making the good person. The most widely discussed is Aristotle’s account.à  For Aristotle, the central concern is â€Å"Ethica† = things to do with character.à  Of particular concern are excellences of character — i.e., the moral virtues. Aristotle, and most of the ancient Greeks really had nothing to say about moral duty, i.e., modern day moral concepts.à  Rather, they were concerned with what makes human beings truly ‘happy’.à  True ‘happiness’ is calledEudaimonia (flourishing / well- being / fulfilment / self- actualization).à  Like Plato, Aristotle wants to show that there are objective reasons for living in accordance with the traditional virtues (wisdom, courage, justice and temperance).à  For Aristotle, this comes from a particular account of human nature — i.e., the virtuous life is the â⠂¬Ëœhappiest’ (most fulfilling) life.

Ford Pinto Case Study Essays

Ford Pinto Case Study Essays Ford Pinto Case Study Paper Ford Pinto Case Study Paper Now more than ever it seems that organizations face ethical or moral dilemmas. The dilemmas that an organization can see are both issues that can be caused by internal or external factors. External issues can be more damaging to the image of an organization. Because of this organizations needs to promptly and properly respond to the issue at hand. In 1971, Ford Motor Corporation faced an ethical issue surrounding the Ford Pinto. During this time executives of Ford made decisions that were considered unethical or immoral. If Ford had had the same morals in 1971 that they do today lives would have been saved. Summary of Case In the early 70’s the Japanese had started to become a major competitor in the United States. In order for Ford to remain competitive Ford’s CEO Lee Iacocca insisted that Ford roll out a car that cost less than $2,000 and weighed less than two tons. This car was eventually called the Ford Pinto. In order for the Pinto to be cost effective the car was designed and manufactured in 25 months rather than the typical 43 months (De George, 2006). The rush and pressure from Ford corporate to produce this car caused quality and safety issues. : The corporate push to produce a car that would appeal to consumers ultimately ended up injuring and costing consumers their lives. From the beginning assembly line workers to the CEO knew that the car had safety issues. Front line Ford employees were not made aware of the decision of the executives to proceed with the Pinto’s production despite the repeat failure of safety test. Ultimately the car was produced and when the Ford Pinto was involved in a rear end crash in the excess of 20 mph the gas tank would explode causing injury, death, or extensive damage to the vehicle. During the 70’s the Ford’s ethics, values, and basic organizational principles varied greatly from today. Ethics and Ford Despite Ford’s executives knowledge of the defects in the Pinto the production was pushed through. The rush to produce the Pinto saved Ford 20 million in production cost and cost Ford 50 million in negligence suits (DeGeorge, 2006). During the 1970’s there was little or no job protection for indviduals that would speak out against an organizations ethical practices. Due to this indviduals feared job loss and refused to speak up. If Ford was faced today with a similar situation to the Ford Pinto situation the outcome would be gravley different. In today’s society there are mesausres that have been put into place that will protect an indviudal if they choose to speak up on the practices of an organization. The National Highway Traffic Safety Administration (NHTSA) has also been developed to ensure the safety of the cars and drives on the roads of the United States. This administrations does not only inforce rules and regulation, but it encourages car manfactures to keep moral and ethical standards high. Conclusion Ultimately the decision made by executives in the Ford 1972 Pinto Case was immoral and cost individuals their lives. The lack of ability for individuals to feel comfortable to speak up and the pressure that executive received caused an immoral issue that could have been prevented. Over the years Ford has learned from their mistake and has not had another issue that compares to the Pinto Case. References DeGeorge, R. T. (2006). Business Ethics. In R. T.

Led Zeppelin essays

Led Zeppelin essays Led Zeppelin was one of the greatest rock bands ever. Their biggest hit Stairway to Heaven, is one of the best rock songs of all time, also. There were four members in the band: John Bonham, John Baldwin, Jimmy Page, and Robert Plant. Jimmy Page was born on January 9, 1944 in Heston, Middlesex U.K. His mother was a doctor's secretary and his father was an industrial personnel officer. In his early life he live on his uncles farm in Northamptionshire, then later his family moved to Epsom, Surrey when his was eight. His life was basically normal, then at twelve he heard Elvis Baby Lets Play House and it change his life forever. He picked up a guitar and some lessons and he was set. He continued to play and in 1965 in was asked to join the Yardbirds (later renamed Led Zeppelin), he first declined and then later joined. In 1968 the Yardbirds broke up and Jimmy had it put together a new band and thats how Led Zeppelin was formed. After Led Zeppelin broke up Jimmy Page continue in playing guitar for many years and still today. (led-zeppelin.org) John Bonham was born on May 31, 1948 in Redditch, Worcestershire UK. His parents were Jack and Joan. He also had two other siblings Michael and Debbie. When he was young he would beat on his moms pots and pans. At the age of ten he got his first snare drum and then at fifteen he got his own drum kit. When he was seventeen he married Pat, who he met at a dance. John played in several bands, and then in August of 1968 Jimmy Page and Peter Grant went to see him play and he accepted the position as drummer for Led Zeppelin. After being with Led Zeppelin for twelve years he died on September 25, 1980 in Windsor, England after a night of heavy drinking.

Marketing Concepts and Planning of Cathay pacific Essay

Marketing Concepts and Planning of Cathay pacific - Essay Example The company believes that their business is marketing knowledge to the travellers. Accordingly, the company is dedicated to Hong Kong where it was established as it continues to make substantial investments to create Hong Kong’s aviation industry and improve the position for Hong Kong as a regional transportation hub. Furthermore, additional to fleet of aircraft, the company also invests in food preparation, aircraft repairs and ground management companies. To Cathay Pacific, a great airlift is not just concerned with the offering of a charming check-in, delicious food and relaxed seats; it is about knowing what a customer desires before they need to request. This is Cathay Pacific company considers that the factual long-term distinction between themselves and their rivals is the exclusive service elegance offered by their staff. Research has shown that their service has an even superior influence on travellers' opinions than the product they provide (Danny 2006, p. 78). To Ca thay Pacific, this shows that training and advancing in their workforce has just as noteworthy profit as their venture in extraordinary technology. For this reason, they have been concentrating or aiming at evolving a culture of service quality. They call this new culture 'Service Honest from the Heart.' Segmentation, Targeting And Positioning Decisions of Cathay Pacific Cathay Pacific is the sphere`s third most cost-effective air company. It is registered and grounded in Hong Kong and at present hires over twenty thousand employees. Segmentation, targeting and positioning are the vital methods of marketing plan. Quantity market is separated into minor sections in which clients share the same set of needs and desires (Graydon 2003, p. 87). Sellers recognize sections or fragments and choose the most practicable and cost-effective sections to target. Cathay Pacific targets trade travellers by chosen account database and mice advertisings. Giving emphasis to the dedication to Hong Kong is a distinction positioning approach of Cathay Pacific (Moyo 2005, p. 59). In addition, Cathay Pacific situates itself as an air company giving superiority services from deep down their hearts. Therefore, its present brand building war for reinforcing this position is â€Å"Individuals and services.† Cathay Pacific manages the complaints of its clients through various channels including comment card, Website, and frontline employee because the number of objections is a sign, which can reveal client approval or contentment indirectly. Accordingly, the company recurrently performs survey concerning the contentment of clients proactively (Greenley 2005, p. 123). The outcome of the contentment shows that client is fulfilled with Cathay Pacific`s services. Content clients lead to client reliability and, in turn, improve brand justice. Nevertheless, Cathay Pacific still copes with two tiered reliability program to uphold and enhance customer reliability. According to Robeson (200 9, p.89), segmentation, targeting and positioning are interrelated steps for planning marketing stratagem. Segmentation has been identified to encompass apportioning the market into numerous smaller sections with comparatively consistent client needs and desires. Targeting includes a company`s choice of deciding on one or more target sections to attend. On the

On the facts, Adam undertook to form Fortress Ltd. for the express purpose of securing a security services project for the Olympic games. All indications are that Adam intends to supervise the project and to ensure that it is accomplished. The mere fact that he is securing the loan for the proposed company’s project substantiates his supervision of the project. Moreover, since the term promoter is essentially a business term, whether or not a person is a promoter is question of fact (Whaley Bridge Calico Printing Co. v Green 1880, 109). On the facts of the case for discussion and pursuant to common law, Adam is for all intents a purposes a promoter. In general a company cannot be held liable for the breach of a contract that was concluded prior to the co mpany’s incorporation (Kelner v Baxter1886 174). In cases where the contract was formed prior to the formation of the company, the person or promoters acting for the proposed company prior to its incorporation are generally liable in a personal capacity (Kelner v Baxter1886 174). ... This was particularly so when Section 36 (C) of the Companies Act 1985 overruled the decision in Kelner v Baxter and essentially codified the decision in Phonogram Ltd. v Lane (1982). Section 36(C) which was further amended by Section 51 of the Companies Act 2006 provided that pre-incorporation contracts would have effect provided there were no agreements otherwise. In the absence of an agreement excluding liability, both the company and the promoter acting as agent would be liable for breach of the contract in a personal capacity (Companies Act 1985, Section 36(C)(1)). Section 36(C) (1) however, did not clear up the confusion as there was some confusion as to whether or not it was necessary for the wronged party to know that the company had not yet been incorporated (Bourne 2011, p. 48). For instance it was decided in (Cotronic (UK) Ltd. v Dexonie 1991,721) that it must be shown that the defendant was purporting to act on behalf of a proposed company. In another case it held that li ability as mutually exclusive in that both the third party acting on behalf of the proposed company and the other contracting party were equally liable for breach of the contract (Braymist Ltd. v Wise Finance Co. Ltd. 2002, 273). In other words, there was no definitive rule of law determining when and if a promoter could be liable for a breach of a pre-incorporation contract. There were instances where a promoter could be liable only if it was clear that the other contracting party did not know that the company was incorporated at the time of entering an agreement. In other instances, liability was assigned to the promoter automatically (Savirimuthu 2003, 203). As the law currently stands, Section 51(1) of the Companies Act 2006 will apply to determine
