An analytical evaluation of eight on-site oral fluid drug screening devices using laboratory confirmation results from oral fluid

A decaying cadaver emits volatile organic compounds that are used by necrophilous and necrophagous insects in order to find their brood substrate. Although volatile organic compounds (VOCs) that are released by carcasses have been identified, little is known about the specific compounds that are used by these insects while searching for a brood substrate. Therefore, we have investigated the chemical ecology involved in the attraction of the necrophagous hide beetle Dermestes maculatus, which feeds as an adult and larva upon decomposing carcasses. Our aims have been to identify the responsible compounds in the odours of the carcass that are important for the attraction of the beetles. Furthermore, we have studied sex- and age-related differences in beetle attraction and tested whether the hide beetle can distinguish between various stages of decomposition by means of the emitted odours. Headspace collection of volatiles released from piglet carcasses (bloated stage, post-bloating stage, advanced decay and dry remains), coupled gas chromatography-mass spectrometry (GC-MS), gas chromatography with electroantennographic detection (GC-EAD) and bioassays were conducted to identify the volatiles responsible for the attraction of the beetles. Freshly emerged male beetles were attracted by the odour of piglets in the post-bloating stage (9 days after death; T(mean) = 27 °C) and the EAD-active compound benzyl butyrate. Statistical analysis revealed a higher relative proportion of benzyl butyrate in the odour bouquet of the post-bloating stage in comparison with the other stages. We therefore conclude that this compound plays an important role in the attraction of hide beetles to carcass odour. This underlines the potential use of D. maculatus for the estimation of the post mortem interval. The decomposition stage at which the female beetles are attracted to the odour of a cadaver remains unknown, as does the nature of this attraction. Pheromones (sexual or aggregation pheromones) might play an essential role correlated with their attraction to carrion and consequently with their attraction to the substrate for mating and ovipositioning.     

An empirical analysis of aftermarket transactions by hospitals

Almost all U.S. hospitals procure their equipment through group purchasing organizations ("GPOs"). Some hospitals subject the prices secured by GPOs to a second round of competition in an "aftermarket," in which vendors both on and off the GPO contract compete for the hospital's business. To measure the extent of the potential benefit to hospitals from another round of competition, we analyzed a database of approximately 8,100 aftermarket transactions for hospital capital equipment. The transactions data suggest that hospitals were able to achieve average savings of approximately 10 to 14 percent across the entire database (2001 through 2010) and a savings of 15 percent on average for 2010 data. These savings may be attributable to many factors, including the compensation structure of GPOs.     

Water alternatives—who and what influences public acceptance?

• Water supports life, society, the environment and the economy, therefore, the task of ensuring a nation's water supply is one of the most fundamental responsibilities of every government. Water management has become a greater challenge due to the increased demand for water as a result of population growth and the impact of climate change on the variability of rainfall. In response, many cities have implemented plans to augment their traditional water supplies (e.g. dams and groundwater) with new or alternative sources (e.g. recycled wastewater and desalinated sea water). Historical evidence suggests that in order for water augmentation projects to be successfully implemented, the support of the general public is required. It is thus critical to understand the factors which influence people's attitudes regarding water‐related matters. The aim of this study is to identify these influencing factors. Results from an empirical study including both qualitative and quantitative components indicate that a number of factors are influential in the public's acceptance of alternative water sources, including research findings, the experience of water shortage, consideration for future generations and news, facts and other publicized information. Notably, politicians and the government were rated by respondents as having a low level of influence. Factors which may determine differences in influence were explored. This revealed a small number of differences for people with low acceptance levels of recycled and desalinated water, and for people with higher levels of education. Systematic differences were identified by comparing the general Australian population with that of Toowoomba, a regional town in Queensland where a referendum on a water recycling project was held. Policy implications are discussed.

Parental Alienation Syndrome in Italian legal judgments: an exploratory study

The present study highlights the characteristics of separated families in Italy for whom Parental Alienation Syndrome (PAS) has been diagnosed during court custody evaluations. The study analyzed the psychological reports of 12 court-appointed expert evaluations of families for whom PAS had been diagnosed. Twelve evaluations that did not receive the PAS diagnosis served as a control group. A specific coding system was used for data analysis. The results indicated that the alienating parents were always the parents who had custody of the children. Children who were diagnosed with PAS were predominantly the only child in the family, had identity problems and manifested manipulative behavior. The consultant in these cases suggested individual psychotherapy for the children and recommended foster care to the Social Services agency.     

Th e Decision to Contract Out: A Study of Contracting for E-Government Services in State Governments

Government contracting, especially for information technology products and services, has accelerated in recent years in the United States. Drawing on the insights of privatization studies, the authors examine the economic and political rationales underpinning government decisions to contract out e-government services. This article tests the extent to which economic and political rationality influence governments' contracting decisions using data from multiple sources: a survey conducted by National Association of State Chief Information Officers, a survey by the National Association of State Procurement Officers, the Council of State Legislatures, and macro-level state data from the U.S. Census Bureau. Important factors affecting the state-level contracting decision are population size, market size, the competitiveness of the bidding process, the professional management of contracts, the partisan composition of legislatures, and political competition. Political rationales appear to play a major role in state contracting decisions. Some arguments associated with markets and economic rationality are clearly politically motivated.     

Joint Working: The Health Service Agenda

The purpose of this article is to examine the policy and practice of collaboration between health and local government from a health servicesperspective. Within this remit, the authors primarily focus on the area of primary care. Four key elements of the post-1997 policy context are discussed: the move from GP fund-holding to Primary Care Groups and Trusts (PCG/Ts); a shift from treating to preventing illness; a drive for implementation by central government; and an emphasis on collaboration. Within this broad context, there are a number of factors which may support enhanced collaboration: the size, scope, responsibilities and budgets of PCG/Ts may well provide an organisational framework which is supportive of joint working. However, the ‘Berlin Wall’ between health and social care has proved to be enduring, and there are aspects of the post-1997 policy context which will continue to inhibit effective joint working, in particular centrally designed performance management systems and the dominance by GPs of PCG/Ts.     

Touching the rainbow

Swiss‐torn painter Angelica Kauffman (1741–1807) was trained in Italy, then moved to London in 1766, where she was to stay for 15 years. Kauffman soon became one of the leading neo‐classical artists, famous for her portraits and history paintings. Her high art pictures won an enormous popularity and were executed, e.g., in interior decorations and as prints. As one of the founding members of the Royal Academy of Arts and belonging to the inner circle surrounding its president, the painter Sir Joshua Reynolds, Kauffman was commissioned for four corner roundels in the ceiling of the Council and Assembly Room in the academy's new home, Somerset House, today at Burlington House. These allegorical paintings on the appropriate theme of the Visual Arts (and part of a larger programme) are discussed in this essay, and especially one of these, representing “Painting”. By means of iconographical analysis it is argued that Kauffman, following the tradition of feminist history painters like Artemisia Gentileschi (1593–1652/53), is not only representing the theory and praxis of the artistic process but in so doing, also comments on the dominant ideology of sexual difference.
