The Initial Changes of Fat Deposits During the Decomposition of Human and Pig Remains

Abstract:  The early stages of adipocere formation in both pig and human adipose tissue in aqueous environments have been investigated. The aims were to determine the short-term changes occurring to fat deposits during decomposition and to ascertain the suitability of pigs as models for human decomposition. Subcutaneous adipose tissue from both species after immersion in distilled water for up to six months was compared using Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry and inductively coupled plasma-mass spectrometry. Changes associated with decomposition were observed, but no adipocere was formed during the initial month of decomposition for either tissue type. Early-stage adipocere formation in pig samples during later months was detected. The variable time courses for adipose tissue decomposition were attributed to differences in the distribution of total fatty acids between species. Variations in the amount of sodium, potassium, calcium, and magnesium were also detected between species. The study shows that differences in total fatty acid composition between species need to be considered when interpreting results from experimental decomposition studies using pigs as human body analogs.     

Public Intellectuals and Think Tanks: A Free Market in Ideas?

The paper critically evaluates the thesis of the interchangeability between the think-tank public intellectual and the academic public intellectual. It suggests that this thesis, while endorsing the rise of the think-tank public intellectual, pronounces the salience of the intellectual-social critic and undermines the authority of academic public intellectuals. It is argued that the think-tank expert doubling as the public intellectuals could limit the political relevance of the academic public intellectual and that the think-tank expert’s monopolization of the public forum could present a threat to the quality of public debates. While recognizing that there are many contradictions inherent in the role of intellectual and that there are now numerous factors that hinder the abilities of academics to act as public intellectuals, the paper emphasizes public academic intellectuals’ contribution to the dynamics of public opinion and the quality of democratic standards. In today’s context, with the omnipresent of media, the new conditions of knowledge production, the neo-liberal ethos and the social prominence of think-tank experts, the sources of the academic public intellectual authority are in a continuous need for reinvestment.     

DNA Profiles from Fingerprint Lifts—Enhancing the Evidential Value of Fingermarks Through Successful DNA Typing

This study evaluated the compatibility of the most common enhancement methods and lifting techniques with DNA profiling. Emphasis is placed on modern lifting techniques (i.e., gelatin lifters and Isomark?) and historical fingerprint lifts for which limited research has been previously conducted. A total of 180 fingerprints were deposited on a glass surface, enhanced, lifted, and processed for DNA typing. DNA could be extracted and profiled for all the powders and lifts tested and from both groomed fingerprints and natural prints with no significant difference in the percentage of profile recovered. DNA profiles could also be obtained from historical fingerprint lifts (79.2% of 72 lifts) with one or more alleles detected. These results demonstrate the compatibility between different powder/lift combinations and DNA profiling therefore augmenting the evidential value of fingerprints in forensic casework.     

Sexual Orientation,Gender Identity,and Adoption Law

The legal landscape surrounding adoption by lesbian, gay, bisexual, transgender, or questioning/queer (LGBTQ) parents continues to be dynamic and variable across the United States, yet the topic is generally viewed favorably by Americans and increasing numbers of LGBTQ adults are becoming adoptive parents. In this essay, we explore intersections of sexual orientation, gender identity, and adoption law. We discuss connections between parenting (including adoption) and marriage rights, highlight the influence of varying legal contexts and discrimination for LGBTQ adults who pursue adoption (including case examples from Florida after the gay adoption ban was lifted), and incorporating the perspectives of adoption‐agency personnel working with LGBTQ clients.     

Politicians,the Representativeness Heuristic and Decision-Making Biases

Political Behavior - Do politicians use the representativeness heuristic when making judgements, that is, when they appraise the likelihood or frequency of an outcome that is unknown or unknowable?...     

The Challenges of Contracting and Accountability Across the Federal System: From Ambulances to Space Shuttles

This article focuses on two questions related lo governmentcontracting and accountability. How are key components of contractingsimilar or different for city, state, and federal governmentsin the United States? To what extent do the three levels ofgovernment share the widely recognized challenges of contractdesign and contract management? To address these questions,we compared and contrasted six contracting cases, two each forlocal, state, and the federal governments. We found that forall governments in the U.S. federal system, the public managementfunctions of contracting are remarkably similar, and that contractmanagement and the achievement of accountability are "weak links"in the contracting process. Our findings do not support thehypothesis that contract management is more effective in localgovernment relative to state and federal governments.     

Signs and symptoms of post-traumatic stress disorder in children

Summary Post-traumatic Stress Disorder in children is a complex interaction of cognitive, affective, and physiological responses to an event that is outside the range of usual human experience and would be markedly distressing to almost anyone. Traumatic stress reactions in children are conscious and unconscious efforts to assimilate an overwhelming event and have been identified in the past as panic reaction, acute grief hysterical reaction, and physical shock. PTSD in children is complicated by multiple issues of developmental stages, family dynamics, physical maturity, genetic predisposition, and cognitive skills. Characteristic symptoms of PTSD which must persist for more than one month include re-experiencing (flashbacks, nightmares); avoidance; numbing of general responsiveness; and persistent autonomic arousal. Children exhibit characteristic PTSD symptoms, but research suggests four criteria specific to traumatized children independent of chronological age and the course of the disorder: 1) visualized and repeatedly perceived memories; 2) repetitive behaviors; 3) trauma-related fears; 4) altered attitudes about life and future orientation. These four criteria appear to remain clustered together in childhood trauma victims even when other diagnosis would appear more appropriate. PTSD in children encompasses a complex spectrum of diagnosis and remains technically intricate for the mental health professional.
