The Food Preferences of the Blow Fly Lucilia cuprina Offered Human Blood,Semen and Saliva,and Various Nonhuman Foods Sources

As human DNA profiles can be obtained from blow fly artifacts, this study aimed to establish the feeding preferences of Lucilia cuprina (Wiedemann) blow flies when offered human biological fluids and nonhuman food sources. One‐day‐old and 3‐day‐old blow flies of both sexes were simultaneously offered human blood, semen and saliva, pet food, canned tuna and honey, and the number and length of visits documented over 6 h. One‐day‐old flies visited pet food and honey most often, but stayed longest on honey and semen. Three‐day‐old flies visited semen and pet food most often, and stayed longest on these food sources. Blood and saliva were the least preferred options for all flies. Overall, flies preferred dry blood and semen to the wet forms. These findings demonstrate that even when other food sources are available, flies at a crime scene may feed on human biological fluids if present, potentially transferring human DNA.     

Lake Taupo: a multi‐sector collaborative partnership towards sustainable development

This paper explores the motivations for and processes of a unique multi‐stakeholder collaboration aimed at the long‐term sustainable development of a region. The region is that of Australasia's largest lake, Lake Taupo, New Zealand. Lake Taupo has geographic features that have not only enabled the development of a strong economy based on tourism, forestry and agriculture but have also generated particular environmental problems. The findings of the case study present highly innovative solutions that are premised on collaboration and on a ‘business case’ for sustainability. From extensive interviews with a wide range of stakeholders, the case confirms extant literature that looks at the roles of leadership, stakeholder engagement, and first movers in bringing about change, but it also highlights further findings that include the surprisingly important role of fringe stakeholders, the difficulties presented by uncertain regulation, and the need to innovate in tailoring solutions to fit the peculiarities of a specific problem.

Community involvement in constructing village health buildings in Uganda and Sierra Leone

Three public health projects in Uganda and Sierra Leone are used to illustrate a new approach to construction of health buildings in villages. Emphasis is placed on community involvement. The health projects were comprehensive and relied on health education, employment of local village health workers, and establishment of village health committees. The objective of community involvement was described as encouragement of people to change their own diets and living conditions. This approach to primary health care is considered to be a strong basis for sustainable social development. Each of the three communities initiated the building projects slightly differently. There was a range of structures: traditional meeting halls, simple rooms with imported materials and a pit latrine, new buildings combining local and imported materials and labor, new nontraditional buildings, rehabilitated existing nontraditional buildings with imported labor and materials, and temporary mobile clinics. Community involvement was at different levels. All three projects were the result of a combined effort of national governments or mission hospitals, nongovernmental organizations, and the host community. The following should be considered before beginning construction: a suitable site, appropriate staff accommodation, the likely motivation of the host community, seasonality, local materials available, availability of skilled labor, and design. A plan of work during construction should include a building design, site supervision, transportation of local and non-local materials, unskilled labor, and skilled labor. Village health committees with or without government help would be responsible for maintenance of buildings after construction. A key feature of this approach is the assessment of the community's ability and capacity to contribute.     

The impact of legal constraints on voter registration,turnout, and the composition of the American electorate

Research on the effects of restrictive voter registration laws has been largely passé for nearly a decade, apparently due to the widespread acceptance of Wolfinger and Rosenstone's (1980) study of voter turnout. Wolfinger and Rosenstone's research indicates that fully liberalized registration laws would produce a larger voting population, which would differ only marginally in its composition from the existing electorate. But their analysis only addresses turnout, not registration itself, and is based on a single sample of the American electorate, 1972. This paper focuses on the impact of restrictive laws on registration and turnout in presidential and nonpresidential election years during the period 1972–1982, relying on data from both the U.S. Census Bureau's Current Population Surveys and the National Election Studies. The results of the analyses do mark important points of difference from Wolfinger and Rosenstone's findings. Ultimately, however, there is no escaping their conclusion that the implications of liberalized voter registration laws on the composition of the electorate would be relatively minor.     

Tolerance and Intolerance, 1976–1998

Early students of political tolerance projected a rapid rise in levels of tolerance, but subsequent research has failed to offer conclusive evidence regarding whether tolerance has, in fact, increased. The General Social Survey (GSS) included the same 15 dichotomous tolerance items in the period 1976–1998, seemingly permitting assessment of trends in tolerance through examination of a standard 0–15 scale. Unfortunately, the validity of these data is uncertain because we cannot rule out the possibility that changes in affect toward the five GSS target groups, not true changes in tolerance, drive movement in the longitudinal series. To address this problem, we reexamine the GSS data from the perspective of past discussions of the meaning of tolerance and intolerance. We argue that that the GSS scale captures two aspects of tolerance: whether respondents are tolerant or intolerant; and, among the intolerant, the breadth and depth of their intolerance. We further argue that the first of these dimensions can be measured validly using the GSS data. Our analyses reveal that, at most, tolerance has increased only marginally in the period 1976–1998.
