Jeff Bezos Makes Another Push for Amazon Fashion. Will It Work Essay

Jeff Bezos Makes Another Push for Amazon Fashion. Will It Work - Essay Example Integral to this effort is Amazon Fashion, a section of main website that sells well-known brands the â€Å"contemporary† category. These are labels that do not carry the astronomical price tags of luxury fashion houses like Chanel and Prada. In 2013 the site also launched its first TV campaign looking forward to persuade shoppers that it can be relied on as a source of swanky merchandise. Moreover, this month, it hired Vogue editor Caroline Palmer to head up editorial duties at the site. Amazon also pushed websites shopbop and Zappos toward a higher-end aesthetic in order to attain its fervent desire for more affluent clothing customers. And for the very first time in New York, a menswear version of Fashion Week will come this summer. Bulbs will flash as photographers hustle to document best looks from the spectacle’s dapper attendees; most creative garments will be showcased on radiant catwalks. All this will be sponsored by Amazon; this announcement was made by the council of Fashion Designers of America earlier this month. Observers say that it is difficult to insert couture items under the Amaxon anner, which they claim to have long thrived on offering a practical, easy way to buy just about everything. Fashion is about experience, it is often impractical, dominated by unpredictable trends and personal teste. However, Amazon is known for being massive vending machine whose brand has only been about convenience and price, but instead they should be concerned with what is missing in the field of fashion, what can be improved upon so as to make their products a trend that everyone looks upon. They are forgeting that all that is done is to meet the customers’ needs, rather than their ambitious move in order to be a two-hundred-billion-dollar company by learning how to sell clothes and food products. If the brands are luxury, aesthetically appealing to the eyes and

Parenting in Diverse Cultures Essay Example for Free

Parenting in Diverse Cultures Essay Culture may influence child activities and behaviors through the organization of the physical and social settings of every day life. Social as well as cultural norms, values, and conventions can direct and control the childs behavior through the progression of social evaluation. Throughout childhood and preadolescence, due to childrens particular need for peer assimilation and closeness, peer evaluation and social recognition in the peer group can play a critical role in the mediation of cultural influences on individual functioning. Moreover, in the development of socialization, culturally shaped parental belief systems and parenting practices can mediate and restrained childrens acquisition of cultural messages. Finally, formal training in educational institutions such as the school constitutes another significant channel for the transmission of human knowledge and cultural values from adults to children in modern societies. Culturally diverse children can have an expectation concerning confidentiality as do American-born children. Also, this concept in fact runs counter to therapeutic attempts to enlist the parents as partners in their childrens treatment. Discretion with culturally diverse adolescents can be particularly challenging. Often, culturally diverse families experience conflict while children reach adolescence and instigate to identify mainly with the values of their American peer culture. On the contrary to the elongated American adolescence phase devoted to ongoing education and the development of peer relationships, culturally diverse parents can have experienced their own abbreviated adolescence cut short by the need to find employment, by early marriage, and/or by parenting. They do not recognize the push for independence among American adolescents. Culturally diverse adolescents can want to pursue the activities of American youth despite knowing their parents would condemn. Researchers are interested in parental ideologies concerning childrearing as they may provide useful information concerning the explanation of different parenting behaviors across cultures. Moreover, it is a practical assumption that parental cognitions, ideas, and beliefs serve a mediating function in development of cultural influences on parental attitudes and behaviors toward the child (Goodnow, 1995). Indeed, it has been found that parents in diverse cultures have different expectations and goals regarding parenting and that socialization goal are linked with parental judgment and valuation of normal and abnormal child behaviors (Hess, Kashiwagi, Azuma, Price, Dixon, 1980). In traditional Chinese cultures, for instance, â€Å"filial piety† is a Confucian doctrine dictating that children vow obedience and reverence to parents. Chinese parents, in turn, are accountable for â€Å"governing† (i. e. , teaching, disciplining) their children, and are held responsible for their childrens failures. While individualistic values are underlined in Western cultures, with children being mingled to be independent and self-assertive (Hess et al. , 1980), Chinese children are socialized to be moderate, well-mannered, reciprocally dependent, and concerned with the collective. Cross-cultural differences in parenting ideology can be illustrated also in different values concerning child independence in collectivistic and individualistic cultures. A sense of autonomy is measured crucial to adaptive development in many Western cultures (Maccoby Martin, 1983), but might not bear such implication to the adaptive development of children raised in other cultures. Indeed, there is little emphasis on socializing children to be independent in Japanese culture (Rothbaum, Pott, Azuma, Miyake, Weisz, 2000). While American mothers are more likely than Japanese mothers to persuade their children personal autonomy and forcefulness such as defending ones rights, Japanese mothers are more likely to socialize their children to be polite and deferential to authority figures (Hess et al. , 1980). Weisz, Rothbaum, and Blackburn (1984) argued that diverse emphases on self-sufficiency might account for such cross-cultural differences as Japanese children showing more self-control and sympathy to others and American children being more self-expressive. Parental belief systems consist of a wide range of thoughts, perceptions, values, and expectations regarding normative developmental processes, socialization goals, and parenting strategies (Goodnow, 1995). Cultural disparities in parental beliefs and values are a major source of involvement to cross-cultural differences in parental attitudes, actions, and behaviors in parenting. Nevertheless, it must be noted that the links between parental beliefs and behaviors characteristically range from weak to modest in the Western literature (Sigel, McGillicuddy-DeLisi, Goodnow, 1992). It is largely indefinite how belief systems might be linked with parenting practices at the cross-cultural level, as these two constructs have not been obviously differentiated in several cross-cultural studies. Parents of diverse culture have the same hopes as well as dreams for their children and families that the general population does. Most desire their children to get a good education and become prolific members of society. In the more traditional families, these desires comprise learning about tribal values, beliefs, and customs. These families want successful children in a manner reliable with cooperative, noncompetitive tribal, community, and family values as well as aspirations (Burgess, 1980). Parents in diverse culture often take an dynamic role in socializing their children concerning the consequences of their ethnicity in the larger society (Harrison et al. , 1990). Oppression provides the framework of teaching about the assaults of typical culture. Parents teach their children to watch for subtle clues about whether they are welcome in a given situation (Cross, 1995). As children mature, they are more well-informed about differences in race, and they come to recognize themselves with a particular tribe; though, they appear to prefer toys, activities, and friendships from the prevailing culture. Parents (Dawson, 1988) emphasize the significance of self-esteem in their children: â€Å"If my children are proud, if my children have an individuality, if my children know who they are and if they are proud to be who they are, theyll be able to meet anything in life† (p. 48). Positive self-esteem provides self-assurance, energy, and optimism to master lifes tasks. This positive sense of self and confidence is significant for parents as well as children. Parents who feel capable in their parenting are more able to involve themselves in their childrens lives outside the home. Parental involvement is significant to the future educational development of their children (Dawson, 1988). In diverse culture families believe that their children should have the opportunity to grow into adulthood with the considerate that they are worthwhile individuals who are equal to all other Americans. American children should believe that they are respected for their culture, as they value the worth of others. They should believe that they are valued in American society and that they can attain in any way they choose according to their individual talents (Noley, 1992). In diverse culture, children view themselves more pessimistically than do their dominant culture counterparts, let say self-concept of Native American children is negatively linked with chronological age and years of schooling. Soares and Soares (1969) found that in spite of living in poverty, disadvantaged children in elementary school did not essentially suffer from lower self-esteem and a lower sense of self-worth. These findings suggest that just being poor is not the leading factor in the low self-esteem of Native American students. Though, researchers have long been interested in family influences on child social and cognitive functioning. The general consent is that family, as a main socialization agent, plays a significant role in the development of individuals adaptive and maladaptive functioning. This belief has been sustained by the results of numerous empirical studies concerning the associations amongst parenting practices, family organization and family socio-ecological conditions, and child adaptive and maladaptive functioning in diverse settings, although different opinions still exist (Harris, 1995). Among family variables, parenting beliefs and practices compose a central theme in the cross-cultural study of upbringing. Several explanations for cross-cultural variations in parenting have been suggested. First, an anthropological viewpoint proposes that differential vulnerability to threats to the survival of children accounts for the changeability in parenting practices (LeVine, 1974). on the other hand, it has been suggested that parental needs to engender the values and attitudes essential for becoming a competent adult, able to achieve expected roles in his or her respective culture, may be related to diverse parenting practices across cultures (Hoffman, 1987). It has also been argued that cross-cultural differences in parenting attitudes and behaviors can reflect variability in beliefs pertaining to childrens distinctiveness and to the world in general (Super Harkness, 1986).

Our aim is to investigate how much quicker Essay

Aim:- Our aim is to investigate how much quicker a reaction happens if the acid we uses strength goes up, and also to see if there is a pattern which could be carried on to higher strength acids. Background Science:- Chemical reactions play a very important part in our life, some even keep us alive (the process of our digestion system is a series of chemical reactions which convert food into chemicals which can be more easily used by our bodies), other circumstances where chemical reactions are used in our bodies that cut down the amount of acid in your stomach, there are also chemicals in washing powder for removing stains by using chemicals called enzymes which speed up the breakdown of the chemicals in stains. All chemical reactions happen at various speeds, such as chemicals in fireworks which react very fast, within seconds of the firework being lit the reaction is over. Slow chemical reactions could be such things as the ripening of cheese so it can mature over time. Some adhesives we use require two chemicals to be mixed depending on the amounts used it could make the glue harden quickly or slowly. Some reactions happen slowly whereas some happen very fast. The name in which we measure a speed of a reaction is called a â€Å"Rate Of Reaction†. It can be measured in two ways, either the rate in which one of the products is produced, one of the products that is produced is gas, you can measure gas in a syringe or in a upturned burette. Another method that can be used is recording mass of the reactant, (how much the mass has added to its weight of lost). The mass could be recorded every minute and could be written like this, 1. 0g/60secs. Variables:- We had four variables to choose from, Temperature, Concentration, Surface area/Pressure and Catalyst. If we were to use temperature we would measure how much quicker the reaction would go if the acid and calcium were heated together, but we would have to keep the temperature at a constant heat as it wouldn’t be a fair test if the reactants were getting hotter and colder. If we were to use a catalyst it would be used to speed up the reaction, but this would be unfair because we wouldn’t be able to measure how much extra speed is being put in by the catalyst. Or we could change the surface area of the reactant, this would give the acid more of a area to act on, to measure this we would have to weigh the calcium first then expose it to the acid for a certain time and then take it out and weigh it, making sure we use the same concentration of acid each time to make it a fair test. We decided to use Concentration, for this we would change the strength of concentration each time and take a volume of gas that is given off every ten seconds. From choosing the variable – Concentration we can measure the rate of gas that is being given of, this could be useful because we could work out how much gas per minute is being given off, from that we can then predict how much gas is being given off for any time you need to find. Prediction:- I think that as the strength of the acid goes up the rate of reaction will go up. Collision Theory:- I think this will happen because the higher the strength of the solution the more particles there are in the solution, which means more collisions more frequently. The acid will hit the calcium carbonate, if there is enough energy in the acid the calcium and acid will react together to give off Carbon Dioxide. The more the particles collide the faster they react. I have made a predicted graph, showing what I think the graph will look like. I have drawn in the lines of best fit showing the steepness of the line. This diagram shows how the acid particles collide with the marble chip to give off a gas. Method:- Set up apparatus as shown above. 1. Measure out desired amount of marble chips. 2. Measure out desired amount of hydrochloric acid – 0. 25 mole first, then when all experiments with 1 mole have been completed go onto 0. 5 mole then 1 mole then 1. 5 and finally 2 mole. 3. Fill up the water bowl. 4. Fill measuring cylinder with water up to 100 ml. 5. Holding hand over the top of the measuring cylinder quickly turn it upside down and place it under the water (as shown above). If the water comes out refill the cylinder and try again. 6. Place tube so one end is coming up in the cylinder under water. 7. Put the marbles in the chronicle flask. 8. Pour in the hydrochloric acid and quickly affix the top with the tube coming out of it into the chronicle flask. 9. Decide at what time you will measure how much gas is given off. We decided to take a reading every 10 seconds, we also decided to start taking the readings at 30 seconds. You measure how much gas is given off by the water dropping in the measuring cylinder. E. g. 10 mls given off in the first 30 seconds. 10. Take these readings for 100 seconds using a stop watch to be precise. I am going to take 3 repeats, I am doing 3 because I can get a fair average from these 3 results. From the averages I will plot a graph to compare the different strength acids. Analysis:- (Graphs). From my graphs I clearly show the variable of different strengths of acids. As I used higher strength acids, the time in which the gas was produced got much faster. As the acids get stronger the lines become more inline. Whereas the 0. 5 points were all over the place. From my results I can see that my prediction was correct â€Å"I think that as the strength of the acid goes up the rate of reaction will go up†. I could see that from my results the strength of acid went up and the speed it took to make the gas went down. This links to the collision theory, that is that as the strength of the acid went up there were more particles to collide on the marble, which meant that more gas was given of due to more particles in the small mixture. The higher the strength of acid the more accurate the results became, we can see this because the range bars get smaller as the strength of the acid gets stronger. From the predicted graph I can see a difference in the results graph. The 1 mole strength acid has taken longer than the 0. 5 mole acid to produce the gas. I will explain the possible reasons for this more in my evaluation. Evaluation:- The main difficulty we faced was with the 2 mole strength acid because it reacted so fast we barely had time to read the times precisely. This may have meant we had unfair results. The main anomalous results were the 1 mole results, because from the information we have (collision theory) it tells us that it is stronger than the 0. 5 mole which means it should be lower than on the graph than 0. 5. But it isn’t. This may have been because the results were read wrong, the acid we used may have been slightly too strong or the marble chips we used may have been smaller which means it is easier for the acids to break down. To improve the accuracy we could use a burette, which are far more accurate than a measuring cylinder or a gas cylinder. Gas Syringe Burette Computer data collectors are a very accurate way of registering the time, also if you were to use a camera recorder so you could look back at it and pause it when it got to the times when you needed to record a time. The results would never be the same because sometimes the measurement of marble chips maybe slightly more or less, or the accuracy of reading the time would be slightly out etc. As I said earlier in my investigation the results seemed to become more reliable as the strength of acid went up.
