Wind Energy: Harnessing the Wind to Generate Electricity

Key facts: - The spinning blades of wind turbines convert energy from the wind's motion into electricity. - Installed US wind power plants had 6,740 megawatts (MW) of electrical capacity in 2004, enough to serve 1.6 million households. - The cost of wind power is competitive with other energy sources. With the Production Tax Credit of 1.9 cents per kilowatt-hour (kWh), wind power costs between $0.03 and$0.06 per kWh, a huge decline from $0.80 per kWh in 1980. - Wind power is one of the fastest growing energy sources in the United States: its capacity increased on average 25 percent per year from 1990 to 2003. Although capacity increased by only 6 percent in 2004, due to the expiration of the Production Tax Credit, the American Wind Energy Association anticipates that over 2000 MW of wind power capacity will be added in 2005, more than in any previous year

Corporate social responsibility: a myth? The example of the 'Round Table Codes of Conduct' in Germany

This paper is concerned with why and how multinational companies (MNCs) voluntarily engage in Corporate Social Responsibility (CSR), especially in social standards. The first part describes the prevailing perspectives on the CSR debate. Then, with the New Institutionalism in Sociology, an alternative view on CSR is discussed. The third part develops the argument that the ‘traditional’ rational institutional myth developed by Meyer and Rowan should be replaced or supplemented by a CSR myth. After that, the case study of “Round Table Codes of Conduct” provides an example of how MNCs deal with this emerging CSR myth

Review of Chagas Disease and Treatment Obstacles to Eradication

The World Health Organization and the Center for Disease Control reports Chagas disease, or American trypanosomiasis, as a major neglected tropical disease prevalent in 21 endemic Latin American countries. The agent of the disease is a single-celled protozoan parasite, Trypanosoma cruzi, and common modes of transmission include infected feces of a triatomine bug, crossing the placental barrier, and blood products. The two phases of infection are acute and chronic, and the three most affected body systems are cardiovascular, digestive, and nervous. Although research has led to several advances in the knowledge of CD, there are gaps in treatment and epidemiological research, leaving millions of people susceptible to infection

Research, relativity and relevance : can universal truths answer local questions

It is a commonplace that the internet has led to a globalisation of informatics and that this has had beneficial effects in terms of standards and interoperability. However this necessary harmonisation has also led to a growing understanding that this positive trend has an in-built assumption that "one size fits all". The paper explores the importance of local and national research in addressing global issues and the appropriateness of local solutions and applications. It concludes that federal and collegial solutions are to be preferred to imperial solutions

Seasonal Response of Workers of the Allegheny Mound Ant, \u3ci\u3eFormica Exsectoides\u3c/i\u3e (Hymenoptera: Formicidae) to Artificial Honeydews of Varying Nutritional Content

Field colonies of Allegheny mound ants, Formica exsectoides, were tested at monthly intervals throughout the summer to assess their preference for artificial honeydews containing varying compositions of sugars and amino acids. In choice tests, foragers significantly preferred high sugar honeydews early in the season, but shifted in mid-season to a strong preference for high amino acid honeydews. Late-season foragers slightly preferred sugars. When offered in equal concentrations, the honeydew sugar, melezitose, was consistently less attractive to foragers than sucrose. However both sugars were readily fed upon, and appeared to attract ants in an additive fashion. No single amino acid was significantly preferred; however the combination of asparagine, glutamine and serine was highly attractive during the mid-season sampling period. The seasonal switch in forager preference between sugars and amino acids coincides with an increase in the amount of actively growing brood
