Role of poultry in the global supply of meat Literature review

Role of poultry in the global supply of meat - Literature review Example There will be techniques discussed to prevent the animals from catching diseases and consumers to consume diseased meat. Lastly, the paper will also look at the advantages of consuming some poultry products like chicken. Role of Poultry in the Global Supply of Meat Breeding of Poultry Capper (2011) elucidates the different types of breeding techniques and names four of the most common types. In-breeding, line-breeding, out-crossing and out-breeding are the most common ones. In-breeding refers to the type of technique where animals that are close relatives are bred together. Line-breeding refers to breeding of animals that are not from the immediate family but could be distant relatives. The family line is the same but relationship is rather distant. Out-crossing is the crossing of animals especially dogs that is related to line breeding but the lines are completely distinct from one another. Out-breeding on the other hand is the breeding of animals that are from different lines. The animals are not the product of line-breeding. Capper (2011) is of the opinion that the demand for poultry products has increased in the past few years and resources like land and water to meet the demands have decreased. The production of livestock has to increase if the global demands are to be met and animal breeding must support it. Capper (2011) proposes that breeding goals have to be implemented on a more frequent basis. As breeding goals helps to improve characteristic of different species, it will help scientists with disease resistance and development or growth in animals. Delgado (2009) elucidates that growth is one of the most important features of breeding goals resulting to improve animal breeding. An animal that grows faster will be able to produce a larger amount in less time. One such example is the salmon fish in livestock marine. After 7 generations of endeavor, salmons can now be slaughtered at half the time it was done 7 generations before. It also now gives 25% m ore protein. Delgado (2009) believes that the major cost incurred in poultry arises from feeding the animals. The total cost in proportion to other cost of production is around 75%. Delgado (2009) believes that the cost will raise even further more in the future as more animal breeding takes place. Because of environment factors the prices of are also expected to rise. Production and reproduction will become more important than ever. Thus productivity traits will become a major part of the breeding goals not only for food purposes but also for the environment. Yoav & Soller (2013) believe an animal welfare is very important in achieving breeding goals. There should be proper breeding centers build in different localities for the purpose of breeding them. They could be far away from the cities but should have two major things. Firstly it should have all the necessary resources like food, medication and other health benefits to make sure that the animal receives proper treatment and s econdly the environment where they are made to breed must be clean, pollution free and fit for the animals in every other sense. Yoav & Soller (2013) believe that animal welfare is not only advantageous for the animals but it also has great many advantages for man. An animal that grows in a healthy environment receiving medication will unlikely be a threat to human life after when being consumed. Scientist in recent years has blamed the local farmers for the lack of responsibility

Business law (Qatar) - Essay Example Qatar is regarded as one of those wealthy countries in the world along with greatest mounting economies in the Gulf Cooperation Council (GCC). It is worth mentioning that Qatar has introduced and developed trademark law for gaining help in conducting a business efficiently in varied domestic regions (Government of the State of Qatar, 2015). According to Qatar law, infringement is deemed to be regarded as one of the crucial issues. Thus, to prevent infringement in Qatar, domestic companies can register their trademarks according to industrial design governing the trademark, which came into effect after the year 2002. Companies are ought to commercially register for trademark law to get qualified for the respective services. Besides, any company in Qatar can use this trademark registration for ten years (WIPO, 2006). The various forms of trademark can be clearly understood from the following tabular representation: According to Qatar Trademark Law no. 3/1978, the Qatari official regulates the defense of trade as well as industrial marks. There lay certain specific processes or steps for registering the trademark for any company in Qatar (Government of the State of Qatar, 2015). According to the article 9 to 12, the processes of registering trademark have been discussed in detail below. Under the trademark law in Qatar, an owner of trademark can resort to civil remedies, if any case of infringement made by third party. Then, only the owner can forward this process along with filing a lawsuit before the court of civil jurisdiction (Simmons & Simmons, 2013). The respective government of Qatar is planning to adopt an effecting law to combat phishing as well as cyber-squatting, but this plan of the government is still waiting for the approval of higher authority of ministry.

Functionalism In Families And Societies

Functionalism In Families And Societies Functionalists view the family as a nuclear family structure, i.e. a mother, father and 1 or 2 children. Murdock surveyed 250 societies from the small hunting tribes to the large industrialised societies. He found that in every society there was some form of a nuclear family, he concluded from this study that the nuclear family was universal. Murdocks definition of a nuclear family is Within the framework of the nuclear family, Murdock identified with four family functions which if were ignored, society would not exist. Sexual, Reproduction, Economic and Education were the four functions. Similar to Murdock, Tallcott Parsons another functionalist had his own views of what functions the nuclear family should contribute to society. He believed that there were two important roles within the family Expressive and Instrumental. The womens role was the Expressive role as she was the one who raised, nurtured and taught the children the norms and values within the home. The mans role was the Instrumental role because he went out to work to provide financial security for his family. Parsons also identified the family as being the primary agent of socialisation and came up with the warm bath theory primary socialisation (norms and values) and stabilisation of adult personalities (support and love for the adults within the family. Criticisms Functionalists view of the family is similar to a fairy tale, because they ignore the family dynamics and in some families the darker side i.e. abuse, neglect and violence through male domination. Marxism A Marxist perspective of the family saw the family as a means of production and cheap labour whereby they are influenced by capitalism in a capitalist society. Marxists identified three main functions which they saw as a way for the family to fulfil for capitalism. Inheritance of Property means that in order for property to be handed down to a legitimate heir, sexual relationships need to be restricted to one person, thus the offspring would be blood related. For this to happen, The monogamous nuclear family developed with the emergence of private property, in particular the private ownership of the forces of production, and the advent of the state, (cited in Haralambos, M. 1985. 340) The second function is the Ideological Functions which families need to fulfil by socialising children with the ideas that there will always be bosses and workers within a capitalist society. The last function looks at the Unit of Consumption whereby families work to produce goods, which are bought by the families to enable them to be fed and clothed, which bring greater profit for the capitalists. Criticisms Marxists ignore the different structures of families which are found in todays society and with this the different roles within the family. Feminism Feministic views of the family are split into 3 groups, similar to that of the key perspectives. Liberal feminists believe that both the male and the females have equal roles within the family when it comes to the household chores and childcare. Marxist feminists view the women as the producer of future workers and womens oppression stems from capitalism and not the family. Radical feminists view of the family structure is one of patriarchal and that men are seen as the enemy. This type of family within society is also seen by feminists as the key institution in its contribution to maintaining social control Criticisms All three branches of feminism view the nuclear family as the most dominant unit within society, as well as believing that all members of the family serve society, performing different functions. Post Modernist A post modernistic view of the family is at the opposite ends of the scale to functionalism. Post modernists believe that in most societies there are diverse and multi-cultural types of families where members within these units are free to make their own life choices as to how, what and where they live, work and socialise within society. Post modernists also believe that everyone is entitled to the same opportunities in education, healthcare and family support as in their view, there are no class divisions (working and ruling classes), in most societies. Zietlin et al summarises this view of the world, The post modern world is shaped by pluralism, democracy, religious freedom, consumerism, mobility and increasing access to news and entertainment, (Zietlin class handout 2009. 92) Criticisms Because of their views of equal opportunities and freedom of speech and choices they ignore the fact that some people can and do make wrong choices with regards to ignoring the norms and values which are passed down the generations which inevitably upsets the social control aspects in some societies. How the roles and relationships of the family have change over time. Sociologists view childhood as Social Construction because they are biologically distinct from adults, (Harris, M. 2008.44) For this reason I will explain the question in two parts. Children The role of the child within a pre-industrial family (pre 1750), was one of equal standing. As soon as the child could walk and talk they were taught the family trade and were expected to carry on the family tradition. After the industrial revolution came the emergence of the industrial family (1800-1900), when children as young as 6 or 7 were sent to work in factories and down coal mines to bring money into the family home, however this brought about higher mortality rates because children werent as strong as adults. The mortality rates went into decline when the modern industrial family emerged (1900-2000), this is because children were starting to be seen as children and not as cheap labour. Experiences of childhood began to emerge for the majority of children within families, however there are still some societies today that still send their children out to work, but this is now not the norm in todays world. Gender roles and relationships During the pre-industrial years both men and women worked together with other family members. However this all changed between 1750 and 1900 when women were expected to stay at home and be responsible for household chores, childcare and producing the future workforce. This type of family structure was very patriarchal the men had the power so they were the dominators in the family. However this started to change when the modern industrial family emerged between 1900 and 2000, as more women were given the opportunity to become educated, this led to more women in the workforce. This led the family to share the household chores and the childcare and sometimes swap roles within the family if the man became unemployed. Diversity of the contemporary family structure What is a family? This question has been raised by many sociologists and the majority of these have all had different opinion. However in answer to this question, a family can be the nuclear or extended type of family, which are 2 or 3 generations living under one roof. This type of family was more common pre-1750 when families worked with and supported each other, and which still does happen in some cultures and societies i.e. Asian families. Other types of family structures which are more common in Britain today are the one parent families, the step families, the divorced families and the gay and lesbian families who have children. Families today are extremely diverse and multi-cultural through social influences from the media, education and global improvements. Conclusion Throughout this assignment I have paid particular attention to the different views of Functionalism, Marxism, Feminism and Post Modernism. I have given an evaluation of each perspective and have briefly described the changes in roles, relationships and structures within families. I have concluded in my evaluation that my opinion of families and households is one that in todays society of choice, freedom, diversity and multi-cultural structures that post modernism is by far the best view and explanation of society today.

Difference And Inequality Essay

City Road is a good place to investigate inequality and differences as it plays host to a variety of different people, businesses and cultures. Inequalities and differences can be observed just by walking along City Road in the changes that have taken place, in the people that we meet and in the shops that we see, and can be measured in in many different ways. Inequality is prevalent all over the world and can be for various reasons. To discover where inequality and difference can occur we can compare the lives and circumstances of different individuals by asking questions and looking deeper into their stories to see if there is a pattern, in doing so we can get a sense of how inequality can occur. In the first video we heard from John Arthur, a homeless resident of City Road. John tells us of his childhood and how he started to drink at a very early age, he tells us that as an adult he made bad choices and even spent time in prison for his actions. John explains how he never felt like he fitted in anywhere, and blames this on his earlier years. This example in my opinion shows an unequal distribution of circumstance and care as a child and has directly impacted his place in society as an adult. As we compare John Arthurs`s story to Mark Hocking the differences are immediately obvious. Mark`s circumstances and social standing are better than John Arthur`s because Mark Hocking is well known and has a respected and well known business. Mark Hocking tells us how he had a car repair garage which did well in the early days, and he even managed to sell a few cars from the forecourt, however due to larger car show rooms emerging Mark felt his place on the street was in danger so he took the opportunity to reinvent his business and is now a well-established company making bespoke architectural items to order. John Arthur and Mark Hocking are excellent examples of how different lives and circumstances can affect your place in society, and how inequality can occur just by where you are born and how it can create differences in opportunities and income. In conclusion Inequalities can be defined in many different ways, through culture, distribution of resources, wealth, social stature and opportunity and many more.
