Chemistry of Depression - Essay Example Depression is mainly seen among females even though it is common among males also. Medical science was confused about this discrepancy in the occurrence of depression among males and females. However, recent studies have shown the reasons. â€Å"Scientists from the Karolinska Institutet, Sweden, showed that the brain's serotonin systems in males and females are different. They think they might have found one of the reasons why more women are affected with depression and chronic anxiety than me† (What Is Serotonin? What Does Serotonin Do?).Apart from Serotonin, dopamine, norepinephrine, melatonin, insulin and prostaglandins are some other chemicals which affect mood and emotions. Dopamine is also an aromatic compound in organic chemistry. It is a kind of neurotransmitter which controls the movement of emotional responses.

The brain regions known as the thalamus and the striatum are affected by dopaminergic activity† (Gromisch).The neurotransmitter dopamine (DA) and the dopaminergic neurones play an important role in schizophrenia and Parkinson's disease (PD).

This paper discusses the Humanitarian Aims of the 1951 Geneva Convention and how the aims have been upheld by countries over the years – particularly the United Kingdom. Background to the Humanitarian Aims of the 1951 Geneva Convention In the year 2001, the world celebrated 50 years of passing the Status of Refugees through the 1951 Geneva Convention. Legal analysts note the humanitarian needs that accompanied the need for the convention. In the first place, Mason (2009) notes that there was a humanitarian need for the convention because of the increasing rate at which the number of refugees was multiplying the world over. She notes that â€Å"over 30 million â€Å"persons of concern to the UN High Commissioner for Refugees† can still be counted in the world today.3† In the midst of the increasing population of refugees, the fundamental human rights spelt out in the Universal Declaration of Human Rights (UDRH) by the United Nations General Assembly of 1948 covers and protect refugees also4.

Even more, there was the realization by the Geneva Convention to the effect that causes and factors that put people in the state of being refugees were mostly, inevitable, unpredictable and unintentional and thus the need to be empathetic towards the plight of refugees.

Spicker (2001) quotes Asa Briggs (1961)7 who defines the principles on which the social welfare system of the United Kingdom operates as â€Å"a guarantee of minimum standards, including a minimum income; social protection in the event of insecurity; and the provision of servi ces at the best level possible.8† Since refugees fall under all these three wings of principles, it has become eminent on the United Kingdom Social Welfare System to over the years protect the rights of Asylum seekers.
