Fair-Play Obligations: A Critical Note on Free Riding

McDermott rejects the argument that an individual, in receiving benefits from a political community, thus incurs a 'fair-play obligation' to contribute to the provision of these benefits. While acknowledging that an individual receiving benefits without contributing is 'free riding' and that free riding may be morally wrong, McDermott denies that such moral lapses entail communities having any right to demand support. Not contributing may be morally objectionable, but individuals may still have a right not to contribute. However, both proponents and opponents of the fair-play obligation claim do not sufficiently differentiate between different forms of free riding. Arguments tend to be based on rights that may or may not be invoked when individuals free ride through consuming externalities. However, this form of free riding does not entail any reciprocal obligations. Yet it can plausibly be argued that when free riding occurs in the case of the production of public goods, then communities can demand support from individuals, and can have a right to do so.     

Reliable, sensitive, rapid and quantitative enzyme-based assay for gamma-hydroxybutyric acid (GHB)

Several assays for gamma-hydroxybutyrate (4-hydroxybutyrate, GHB) have been developed based on the enzyme gamma-hydroxybutyrate dehydrogenase (GHB-DH). Enzymatic oxidation of GHB by NAD+ is coupled to diaphorase-mediated reduction of pro-dye to yield colored product. GHB-DH from Ralstonia eutropha was cloned and expressed as a stable fusion protein easily purified by affinity chromatography. Quantitative initial velocity and endpoint versions of the assay in solution are described. Michaelis-Menten parameters for oxidation of GHB and ethanol were estimated. A semi-quantitative "dipstick" version of the assay on paper also is described. Both solution endpoint and "dipstick" assays are sensitive to about 0.05 mg GHB/mL using 10 microL of sample. Ethanol at concentrations possible in urine and agents used to stabilize physiological fluids for forensics analysis do not interfere significantly. The "dipstick" assay also allows detection of GHB in alcoholic beverages after evaporation of about one-fourth drop of beverage before testing. The enzymatic assay for GHB is reliable, sensitive, inexpensive and rapid.     

Investigating polyurethane foam as a form of trace evidence.

The aim of this study was to determine whether polyurethane (PU) foam fragments from different sources could be discriminated from each other. Low and high power microscopy was used to determine whether or not foam fragments were distinguishable from each other under various lighting conditions. Once similar foam fragments were declared microscopically indistinguishable, the visible range microspectrophotometer was highly competent in further distinguishing the spectral characteristics in various fragments from each other. Foam fragments from the same source were shown to display no microscopical or chemical variation. Conversely, it was possible to make clear distinctions between foam fragments from different sources.     

Identification of Missing Norwegian World War II Soldiers,in Karelia Russia

This article presents the multidisciplinary effort in trying to identify the skeletal remains of 100 Norwegian soldiers serving in the German army, killed in Karelia Russia in 1944, from the recovery of the remains through the final identification using DNA. Of the 150 bone samples sent for DNA testing, 93 DNA profiles were obtained relating to 57 unique individuals. The relatives could not be directly contacted as the soldiers were considered as traitors to Norway; therefore, only 45 reference samples, relating to 42 cases of the missing, were donated. DNA matches for 14 soldiers and 12 additional body part re‐associations for these individuals were found. Another 24 bone samples were re‐associated with 16 individuals, but no familial match was found. More than six decades after the end of WWII, DNA analysis can significantly contribute to the identification of the remains.     

Nondestructive Biological Evidence Collection with Alternative Swabs and Adhesive Lifters

In forensic science, biological material is typically collected from evidence via wet/dry double swabbing with cotton swabs, which is effective but can visibly damage an item's surface. When an item's appearance must be maintained, dry swabbing and tape‐lifting may be employed as collection techniques that are visually nondestructive to substrates' surfaces. This study examined the efficacy of alternative swab matrices and adhesive lifters when collecting blood and fingerprints from glass, painted drywall, 100% cotton, and copy paper. Data were evaluated by determining the percent profile and quality score for each STR profile generated. Hydraflock^® swabs, BVDA Gellifters^®, and Scenesafe FAST? tape performed as well as or better than cotton swabs when collecting fingerprints from painted drywall and 100% cotton. Collection success was also dependent on the type of biological material sampled and the substrate on which it was deposited. These results demonstrated that alternative swabs and adhesive lifters can be effective for nondestructive DNA collection from various substrates.     

Toward Better Outcomes for Families Through Innovative Dispute Resolution Programs in England

This article explores and shares the learning from two of Cafcass’ innovative dispute resolution pilot programs. The programs aim to improve outcomes for families against the backdrop of rising private law demand in England, while keeping the child at the center. The Positive co‐Parenting Programme pilot provides a structured intervention to reduce conflict and promote timely resolution for children and families in complex cases. The Support with Making Child Arrangements pilot explores whether the provision of a package of support to parents ahead of the first court hearing can help them come to safe agreements about their children without the need for court intervention.     

THE ROARING SILENCE: FEMINIST REVISIONS IN THE EDUCATIONAL POLICY LITERATURE

Absent from assessments of feminism's influence on the academy and the disciplines is an evaluation of the impact of feminist thought on policy research. The purpose of this paper is to evaluate feminist scholarship's presence in the core policy and higher education journals. The first section of the paper explains why it is important to consider the influence of feminism on the policy literature. This is followed by a discussion of what is meant by feminism in the context of this paper. The third section presents the methodology used in evaluating the literature. The paper concludes with a discussion of the findings and implications
