Religious perspectives on umbilical cord blood banking

Umbilical cord blood is a valuable source of haematopoietic stem cells. There is little information about whether religious affiliations have any bearing on attitudes to and decisions about its collection, donation and storage. The authors provided information about umbilical cord blood banking to expert commentators from six major world religions (Catholicism, Anglicanism, Islam, Judaism, Hinduism and Buddhism) and asked them to address a specific set of questions in a commentary. The commentaries suggest there is considerable support for umbilical cord blood banking in these religions. Four commentaries provide moral grounds for favouring public donation over private storage. None attach any particular religious significance to the umbilical cord or to the blood within it, nor place restrictions on the ethnicity or religion of donors and recipients. Views on ownership of umbilical cord blood vary. The authors offer a series of general points for those who seek a better understanding of religious perspectives on umbilical cord blood banking.     

Evolving Federal Policies and Their Implications for Greenbook Interventions

This article addresses the influence of the Greenbook on federal policy in the past 20 years and traces the history of federal policy responses to the co‐occurrence of domestic violence and child maltreatment. While there has been some success in getting the domestic violence and child abuse fields to embrace equally the needs of adult and child survivors of domestic violence, federal legislation has progressed slowly, reflecting that ambivalence. Strengthening cross‐system policy advocacy and increasing evidence that addressing domestic violence improves outcomes for children are identified as ongoing needs.     

Avoiding overstating the strength of forensic evidence: Shrunk likelihood ratios/Bayes factors

When strength of forensic evidence is quantified using sample data and statistical models, a concern may be raised as to whether the output of a model overestimates the strength of evidence. This is particularly the case when the amount of sample data is small, and hence sampling variability is high. This concern is related to concern about precision. This paper describes, explores, and tests three procedures which shrink the value of the likelihood ratio or Bayes factor toward the neutral value of one. The procedures are: (1) a Bayesian procedure with uninformative priors, (2) use of empirical lower and upper bounds (ELUB), and (3) a novel form of regularized logistic regression. As a benchmark, they are compared with linear discriminant analysis, and in some instances with non-regularized logistic regression. The behaviours of the procedures are explored using Monte Carlo simulated data, and tested on real data from comparisons of voice recordings, face images, and glass fragments.     

New developments in SPME Part 2: Analysis of ammonium nitrate-based explosives

Solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry (GC-MS) is a simple, reliable technique for the recovery and analysis of many organic explosives. However, this technique is impractical for the analysis of ammonium nitrate-type explosives due to the extreme polarity, low molecular weight, and high volatility of the amine moiety. This article describes an initial investigation of a derivatization process utilizing alkylchloroformates that converts ammonium nitrate and methylammonium nitrate into a form suitable for recovery by SPME and analysis by GC-MS.     

Metal concentrations in plants and urine from patients treated with traditional remedies

A number of traditional South African herbal remedies which are associated with morbidity and mortality were analysed for selenium, manganese, copper, lead, zinc and mercury content. Few showed high levels of toxic metals, but in these the concentrations were sufficiently high as to cause concern since there is no quality control on the production of these remedies, which are the accepted form of medication for over 80% of the population. Urine samples, obtained from 65 patients admitted to hospital following treatment with a traditional herbal remedy were also analysed for metals. Only a small number of the patients had abnormally high levels of metal excretion. These data suggest that, in contrast to experience with traditional Chinese and Indian preparations, metal contamination from plants seems not to be a problem in traditional South African remedies.     

Mediation and Psychotherapy: Two Sides of the Same Coin?

Some mediators believe that mediation and psychotherapy are quite similar, and that when doing mediation, the mediator also is practicing an art form similar to psychotherapy. On face value, some forms of mediation (e.g., evaluative) and some forms of psychotherapy (e.g., psychoanalysis) are so far apart in theoretical conception and in actual practice that they cannot be compared meaningfully. However, the forms of mediation known as facilitative and transformative and the forms of brief or focused psychotherapy that often involve families or couples do have considerable similarity. Overall, numerous resonances exist between these two approaches to mediation and to couples or family-oriented psychotherapies, especially when differences in terminology, licensure, and training requirements are not allowed to obscure commonalities.
