Disappearance of ethyl glucuronide during heavy putrefaction

Adrenocorticotropic hormone (ACTH) is involved in systemic reactions to stress. The aim of the present study was a comprehensive analysis of serum and cerebrospinal fluid (CSF) levels of ACTH, and the pituitary immunohistochemistry with special regard to fatal hypothermia in routine forensic autopsy cases (n=162: 5-97 years of age; 114 males and 48 females; 4 h to 3 days postmortem, median, 19.2 h). The ACTH concentrations were independent of the postmortem time, gender, or age of the subjects. The serum ACTH level was similar to the clinical reference value for sharp instrument injury, fire fatality, and hypothermia, but was lower in other groups including hyperthermia, in particular for asphyxia and poisoning. The CSF level was usually much higher than the serum level, but was significantly lower for hypothermia and hyperthermia than in other groups (p<0.01). The rate of ACTH-immunopositivity in the anterior pituitary was low in cases of fatal hypothermia and hyperthermia, while it was high in cases of blunt injury, fire fatality, and acute ischemic heart disease. These observations showed that ACTH levels in the serum and CSF depended on the cause of death. The serum level was maintained despite a low CSF level and pituitary immunopositivity for fatal hypothermia, while the serum and CSF levels as well as pituitary immunopositivity were decreased for hyperthermia.     

‘There is no racism here’: public discourses on racism,immigrants and integration in Denmark

ABSTRACT

Jensen, Weibel and Vitus's article critically discusses contemporary Danish policies aimed at the elimination of ethnoracial discrimination, drawing on policy analyses and qualitative interviews with local and national authorities in Denmark. It illustrates how questions of discrimination and racism are marginalized and de-legitimized within the dominant integration discourse, resulting in the marginalization of anti-racism in policymaking. The side-stepping of racism is being naturalized in public policies through strategies of denial and by addressing discrimination as a product of ignorance and individual prejudice rather than as embedded in social structures. The authors examine how immigration, integration and (anti-)racism as concepts and phenomena are understood and addressed in Danish public policies and discourses. Despite denials of racism in Denmark, Jensen, Weibel and Vitus show that, based on re-definitions of identities and relations, it continues to exist and is evident in public debates and policies on immigration and integration.

Analysis of histomorphometric variables: Proposal and validation of osteon definitions

Histological analysis of bone tissue has been used to explore a variety of questions relating to age-at-death, habitual behaviors, health, and nutritional stress. Identification of intact and fragmentary osteons is of key interest to many researchers in these studies, yet the definitions of these features vary between researchers making cross-study comparisons problematic. Furthermore, histological variable definitions are often ambiguous or require subjective classifications by the observer. As a result, and as indicated by previous studies, observer error and misclassification of certain variables, namely intact and fragmentary osteons, can be significant. This study proposes new definitions for intact and fragmentary osteons that are designed to limit observer subjectivity and also explore efficacy of combining osteon types into one variable. A sample of 30 6th rib cross-sections from a modern forensic population was used to test the validity of the proposed definitions. Observations of intact osteon population density (OPD(I)) and fragmentary osteon population density (OPD(F)) were made by three observers for each cross-section. These observations were used to explore the interobserver error associated with the proposed definitions and determine if combining variables into one variable (OPD) mitigates persisting classification difficulties. Results indicate that the proposed definitions significantly reduce interobserver error and misclassification of intact and fragmentary osteons. However, the interobserver error associated with fragmentary osteons is still high. Evaluation of the variables independently indicates that combining variables has potential to reduce the predictive strength of an age estimation model and the ability to interpret age-related bone remodeling.

Cream‐Skimming,Parking and Other Intended and Unintended Effects of High‐Powered,Performance‐Based Contracts

As performance‐based contracting in social welfare services continues to expand, concerns about potential unintended effects are also growing. We analyze the incentive effects of high‐powered, performance‐based contracts and their implications for program outcomes using panel data on Dutch cohorts of unemployed and disabled workers that were assigned to private social welfare providers in 2002 to 2005. We employ a difference‐in‐differences design that takes advantage of the fact that contracts gradually moved from partial performance‐contingent pay to full (100 percent) performance‐contingent contracting schemes. We develop explicit measures of selection into the programs and find evidence of cream skimming and other gaming activities on the part of providers, but little impact of these activities on program outcomes. Moving to a system with contract payments fully contingent on performance appears to increase job placements, but not job duration, for more readily employable workers.     

Organizational form and performance: An empirical investigation of nonprofit and for‐profit job‐training service providers

While research on the distinctions between for‐profit and nonprofit organizations and their changing service sector shares is vast, there is comparatively little empirical evidence on the consequences of their differing attributes for social program outcomes. This article presents research on publicly subsidized for‐profit and nonprofit job‐training service providers, namely whether organizational form influences client enrollment, service delivery activities, or performance, as measured in terms of participant outcomes. The findings show that nonprofit providers were not more likely to serve more disadvantaged clients and that neither for‐profit nor nonprofit service providers were consistently more effective in increasing participants' earn‐ings and employment rates. When performance incentives were included in service providers' contracts, contractors of all forms performed significantly better across all participant outcomes examined. © 2000 by the Association for Public Policy and Management.     

One Standard Fits All? The Pros and Cons of Performance Standard Adjustments

Despite the wide‐ranging use of performance measures within the public sector and the growing use of performance bonuses to recognize performance achievements, the use of formal performance standards adjustment procedures in public performance measurement systems is relatively rare. Burt S. Barnow of Johns Hopkins University and Carolyn J. Heinrich of the University of Wisconsin–Madison set forth the basic arguments in favor of and against the use of formal or informal procedures for adjusting performance expectations. They describe how performance standards adjustments processes are currently (or have been) in use, review the evidence of their effectiveness or problems encountered in their application, and explore the consequences of the inadequacy of performance standards adjustments. The authors offer recommendations for the improvement of public sector performance measurement systems and conclude why this area remains fruitful for future research experimentation. The nice thing about standards is that there are so many of them to choose from. —Andrew S. Tannenbaum
