On social work's theory - Essay Example roviding services (e) with most of these services located within the context of the welfare state and (f) social work is a composite of knowledge, skill and values (Ife, 1997). This has been the traditional framework within which social work has been existing, but this is becoming â€Å"increasingly out of step with the reality of the contemporary practice context†.(Ike, 1997: 12). The hitherto existing system has produced an increase in individual worker case loads, with less levels of control over one’s work while also faced with ethical dilemmas. The disparity between the traditional role that has been ascribed to social work and the reality of actual practice has resulted in critical reviews being instituted of the existing theories that drive social work and how they can be improved. This essay will examine and critique two specific social work theories (a) crisis intervention theory and (b) feminism. A crisis occurs when there is a source of stress that arises in the environment. There are three interrelated factors that are responsible for the generation of a crisis (a) a hazardous event which poses a threat (b) the threat is posed to the person’s instinctual needs, which may also be linked to earlier threats that may have occurred, thus making a person vulnerable to the threat and (c) the inability to respond appropriately to the crisis with an adequate level of coping mechanisms.(Rapoport, 1965:25-26). Dealing with crises is an integral part of social work, because it is a time when people need help. Situations presenting danger or opportunity call for effective decision making by social workers. The crisis theory states that in a developmental or situational crisis, the habitual ways of coping do not work, either because the situation is too new and has not been anticipated or because the events in question are too overwhelming for individuals to deal with. The underlying assumption of the crisis theory is that there are a number of needs, such as

Energy Sources of the Future - Essay Example Biomass Biomass is energy from organic matter and is usually in the form of â€Å"clean† carbo-hydrogen gas or COH2 (Valone). Biomass is also known as biofuel and is produced from organic material such as woodchips, animal wastes and seaweed (â€Å"Biomass†). These organic components are made into oil, natural gas or methanol. The COH2 gas derived from biomass â€Å"burns cleanly, [produces] water vapor† and a limited amount of CO2, which is the one the biomass consumed while it was still growing as a plant (Valone). David Wallman patented the process of producing COH2 from any biomass solution, and this is currently used as â€Å"municipal sewage treatment† and perhaps a replacement for foreign oil in the future (Valone). The biomass power station, which operates using David Wallman’s patented process, involves the burning of the animal or plant wastes. The heat that is produced from the burning is converted into steam and this steam powers the tur bines that convert mechanical energy into electricity (â€Å"Biomass†). When it comes to availability and renewability, the availability of biomass depends on the supply of organic wastes, which are actually relatively cheap to use (â€Å"Biomass†). ... Perhaps the only environmental issue associated with biomass is the greenhouse gas, which results from the combustion of organic fuel or biomass (â€Å"Biomass†). This would naturally bring about pollution. Other harmful effects of biomass production include destruction of the ecosystem, loss of biodiversity, competition for land and food, and excessive demand of the organic matter for water (Langeveld & Corre). Wind Power Wind power is obviously another very good alternative to fossil fuel use, and one that is becoming a more popular option in the United States (Walker). At the speed of around 25 km per hour, wind power can be used to produce electricity from towers with wind-blown propellers. The mechanical energy from the movement of the propellers is then converted into electricity (â€Å"Wind Power†). Wind power is both available and renewable because it needs no fuel; therefore, it is produced for free by the wind, except in some places which are not naturally win dy (â€Å"Wind Power†). Coastal areas, as well as open plains and the tops of rounded hills are the perfect places for the construction of wind farms because of the high availability of wind in these areas (â€Å"Wind Power†). Wind power is relatively practical and cheap at the cost of around â€Å"4 cents per kilowatt-hour† and is usually put up as â€Å"offshore wind farms† in open-water areas (Walker). In fact, Ireland’s eight-mile Arklow Bank Offshore Wind Park is made up of wind towers that can provide electrical power for 16,000 homes (Walker). As to environmental impact, wind power does not produce any greenhouse gases or other toxic waste products (â€Å"Wind Power†). Nevertheless, the propellers can occasionally kill birds that
