Biotechology Use of Commerical and Agricultural Land

Biotechnology is blazing a new trail for the use of commercial and agricultural land. Genetically modified crops are being harvested and placed into our food chain. Currently, there are many benefits of genetically modified food, but the current risks of this newfound technology are undefined. The on-going debate of biotechnology shows conflict between, Agri-biotech investors and their affiliated scientists who consider agricultural biotechnology as a solution to food shortage, and independent scientists, environmentalists, farmers and consumers who warn that genetically modified food introduces new risks to food security, the environment and human health such as loss of biodiversity (Magharri, Mohajer, and Ali). Genetically modified foods could benefit mankind greatly, as long as the reward outweighs the potential risk involved with genetic modification. Roughly 200 years ago Thomas Malthus proposed a hypothesis in which he believed the human population would continue to grow at suc h a rate that the human population would outnumber the available food supply (Nayak, Pandey, Ammayappan, Ray). The world’s population continues to grow at a high rate. For example, the world’s six billionth citizen was born in 1999 to the country of Serbia (Nayak, Pandey, Ammayappan, Ray). The hypothesis created by Malthus has led to advances in technology with agricultural sciences. These technology advances came directly in the form of biotechnology and genetic engineering. These advances

Gendered Roles Of The Police Force Essay - 2083 Words

The law enforcement sector is one that all members of society have been exposed to whether it be from personal experience, hear-say or representations in the media (Horton and Smith, 1988). These exposures to the police force although from inconsistent sources, have one key consistency, they are highly gendered and hyper- masculine (Wells and Alt, 2005). The police force has experienced great advances in terms of gender relations since the 1980s, however gender still influences the trends, forces and tensions that shape what it is to be a woman in law enforcement (Wells and Alt, 2005). Gendered issues in the police force occur within the organizational approaches to management style, attitudes and discourses around sexual assault and domestic violence and gendered media representations. Although these issues systematically disadvantage women in the police force, there is also evidence of organizational shifts toward transformational management and communication, and away from transac tional management and hyper- masculinity (Silvestri, 2007). This has carved out a path for women in the police, and shown that the gendered police force as we know it is in a state of flux. It is slowly moving away from an industry that ostracizes women and into one that embraces the difference women bring as a way forward for the organization. I chose the police force as my area of research because I have a number of ties to the New Zealand police and at one point considered joining.

Gender expectations and prejudices that arose out of the Guatemalan Civil War have developed a machoist, misogynistic society that is strife with physical and sexual violence toward women through which this societal violence has been entrenched through state inaction. Societal gender roles and expectations are perverse in Guatemala.

Violence, as defined by the World Health Organization is the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community that may result in various harms ranging from psychological harm and deprivation to injury and death. From an anthropological perspective, all dimensions ofRead MoreA Critical Discussion On Gender, Masculinity, Power, And Gender Politics1656 Words   |  7 Pagesexample it was found that 40% of households are run by women and often fathers are absent during childhood which thus affects aspects of gender within men such as masculinity. Morell et al. combine statistics with a strong analysis of South African gendered history to analyse hegemonic masculinity. To further their research, they draw on Connell’s framework which studied gender, p ower, masculinities and hegemonic masculinity (1995). This framework altered studies in South Africa regarding gender asRead MoreHow Does Biological Sex Affect Society?899 Words   |  4 Pagesbelieve that there are three big influences that try to keep people in a cis-gendered box. Those constricting influences are familial relationships, societal pressures, and the last are institutional incentives. Societal pressures and what is expected from people of each gender also make people conform to certain behaviors of personhood. Society is able to enforce this by instilling core values that we all feel like we must police each with. I will speak on the male perspective of this and for men thereRead MoreThe Politics Of Suicide By Maria Teresa Brancaccio Essay1587 Words   |  7 Pagessuicide in the years leading up the Emile Durkheim. It wasn’t until the age of the Enlightenment that the concept of taking one’s own life was deemed worthy of scientific analysis (Brancaccio, Engstrom, Lederer, 2013). It was during this time that police, physicians, and mental health care providers began to determine the indicators of such potential behaviors and began to see such rising trends as modern social dilemma (2013). In 1820, due to the work of Andre-Michel Guerry and Adolphe QueteletRead MoreGender Inequality In The Police1751 Words   |  8 Pagesway we interact in social settings.

The story revolves around a young woman in the Gold Coast in 1876 bringing a man who had enslaved her to court. In this story, gender is the underlying driving force for many of the events that take place, and can be seen even in parts of the story that were created by the authors. Gendered issues can sometimes be subtle, as they are often unspoken aspects of society, reinforced by cultural norms and behaviors. As a result, gendering was the most important problem faced whenRead MoreThe Black Lives Matter Is A Movement1659 Words   |  7 PagesIn 2013, a movement called Black Lives Matter, started to advocate their motto and cause for stopping police brutality and racial injustice.
