A Molecular Key for the Identification of Blow Flies in Southeastern Nebraska*

Abstract: Immature blow flies (Calliphoridae) are typically the first colonizers of cadavers. Identification of the early instars using traditional, morphology‐based keys is difficult because of their small size, similarity, and simplicity in external morphology. Information derived from molecular genetic data would augment the accurate identification of immature flies. Nine species of blow flies commonly found in southeastern Nebraska were used to examine the utility of molecular‐based keys. Polymerase chain reaction–restriction fragment length polymorphisms (PCR–RFLP) were investigated with 10 common, inexpensive, restriction enzymes from an amplicon of approximately 1500 bp spanning the mitochondrial cytochrome oxidase I gene. A simple molecular taxonomic key, comprising RFLP from the restriction enzymes HinfI and DraI, enabled the differentiation of all species used. Further development of PCR–RFLP, including more extensive and intensive examination of blow flies, would benefit forensic laboratories in the accurate identification of evidence consisting of immature blow flies.     

Planning for governmental efficiency through staffing allocation

The planning of personnel requirements for the various divisions of a government agency is a prerequisite to the preparation of reasonable operational budgets. This study describes a method for developing baseline estimates of personnel requirements in public agencies, by adpting traditional task analysis and work measurement approaches to teh broader framework of organizational theory. An application to determining the staffing requirements at the National Science Foundation for Fiscal Year 1979 - 1981 illustrates the method.     

Rewriting the “dirty war”: State terrorism reinterpreted by the press in Argentina during the transition to democracy

Abstract

The Argentine press reinterpreted the period of dictatorial military rule (1976–1983) in terms of an interest in the continuity of democratic protections. La Voz del Interior, the newspaper of record in the provincial capital and second largest city of Cordoba, sought to censure, subordinate, and yet reintegrate the military within a democratic institutional ideology. This study uses discourse analysis to characterize 10 elements of a model of coverage of state‐sponsored terrorism: (1) perpetrators, (2) victims, (3) target population, (4) violence and violation, (5) motives or intentions of the perpetrators, (6) fear or terror among the populace, (7) outcomes or changes in the target population, (8) news sources, (9) remedies and projects, (10) and probable responses or appropriated uses by readers or the press. In 1985–1986, when the elected government sought to judge and castigate senior junta commanders, La Voz supported establishment continuity by legitimating societal actors, including the military, even though its members were perceived as having violated basic societal values.     

Anxious Moments: Openings in Negotiation

Even experienced negotiators often feel anxiety about beginning a new negotiation. Subjects in this study described these opening moments with vivid imagery and metaphors, among them: lurking wolves, alligators, tightropes, and rushing trains. People's deep-seated worries can be triggered by several factors: doubts about personal competence, fear about the attitudes and behavior of other parties, and the inevitable uncertainty about what path negotiation will take. The author compares openings in other contexts, notably in the arts, to illustrate how the impact of anxiety need not be entirely negative. These feelings can also spark creativity and support constructive relationships.     

A survey of micro-enterprise in urban West Africa: drivers shaping the sector

This article identifies some key factors shaping the micro-enterprise sector in urban French West Africa. Drawing on interviews with micro-entrepreneurs and micro-finance practitioners in Benin, Burkina Faso, Niger, and Togo, the study explores the needs, characteristics, motivations, and success factors for micro-entrepreneurship in the region, together with some of the impediments to the growth and success of micro-enterprise ventures. It was found that those operating micro-enterprises in the informal economy are entrepreneurs principally by necessity, and that their most basic needs tend to drive their business activities and behaviours. It was also observed that their success was constrained by a number of barriers, including poor access to capital, poor training, and general aversion to risk. As a result, the development of the micro-enterprise sector in urban French West Africa has been sub-optimal, and the authors conclude that this situation may persist unless broader economic and social barriers are addressed.
