Musculoskeletal stress marker (MSM) differences in the modern American upper limb and pectoral girdle in relation to activity level and body mass index (BMI)

Obesity is a widespread condition affecting modern Americans. The prevalence of obesity has led to questions of how it can affect the skeleton, and if so can it be identified in unknown skeletal material. This study attempts to decipher the effects of activity level and body mass in modern Americans by employing musculoskeletal stress markers (MSM) to estimate osseous responses to workload and body weight. A total sample of 108 skeletons of known activity level and body mass index (BMI) was observed for MSM in the upper extremity (excluding hands). The entheses selected included arm muscles used during the sit-to-stand transition, which is common in most persons, regardless of activity level and BMI. Using the three categories: normal, active, and obese, logistic regression was calculated on MSM to ascertain which markers were the best indicators of these three categories. Numerous muscles of the upper limb were significant predictors of activity level and body mass, although they did not perform much better than chance. MSM may be used as predictors of activity level and/or BMI in forensic contexts; however, they should be used in conjunction with other indications of workload and/or BMI.     

Reality bites--A ten-year retrospective analysis of bitemark casework in Australia

Criticism of forensic science, particularly that of bitemark analysis, has become increasingly common in the last decade. Much of the criticism directed at forensic odontology cites cases where miscarriages of justice have occurred when erroneous, over-confident or even false bitemark evidence has been tendered by odontologists. Despite Australia's own experience with such cases in the past, it is postulated that this does not represent the true nature of bitemark analysis as practiced by odontologists today-at least in this country. A review of 119 cases from the last 10 years confirms that 'identification' of a suspect is rarely, if ever, offered, and that conclusions reached by odontologists with respect to bitemark analysis are generally conservative. However, the results of this study also indicate that in a small but significant proportion of cases, there is still some tendency to reach conclusions that could be considered over-confident when considering the overall quality of the physical evidence offered. It is suggested that odontologists should avoid making conclusive remarks regarding the origin of the mark, or the identification of a perpetrator, when such comments are realistically precluded, given the low evidentiary value of the mark itself.     

Scientist entrepreneurship in Saudi Arabia

This paper examines scientist entrepreneurship at universities in Saudi Arabia. It is the first paper to examine scientist research in the context of the Middle East and, in particular, Saudi Arabia. In this paper we hypothesize that scientist entrepreneurship is positively influenced by experience, gender, social capital, human capital, and university and other institutional policies encouraging commercialization activities. To test our hypotheses, we use data from a unique survey of scientists from three universities in Saudi Arabia. The paper finds that there are key elements to scientist entrepreneurship that provide a sharp contrast to what has been established in the literature based on studies from the OECD countries. Finally, managerial implications are discussed and future research is recommended.     

The application of anodic stripping voltammetry to forensic science I. The construction of a low-cost polarograph

Intended for forensic gunshot residue analyses and other applications, a low-cost (about $250.00) polarograph was constructed. This instrument is essentially' an operational amplifier version of a three-electrode potentiostat containing a voltage ramp generator, a scan amplifier, an amplifier and a current-to-voltage converter, two voltage followers and an electrolysis cell. An anodic stripping procedure was developed for the simultaneous determination of a zinc, cadmium, lead, antimony and copper mixture, and used for testing the instrument. Effects of pre-electrolysis time, concentration changes, presence of other species and overlapping were also studied.     

The Intention Debate in German Criminal Law

Abstract.  This article considers the various suggestions that have been put forward by German scholars to replace the traditional concept of intention, which the author has criticised elsewhere ( Taylor 2004 ). The debate on this topic has become a minor academic industry in Germany, and should be better known as the English-speaking world struggles with its own concepts of intention. Despite the great amount of effort and ingenuity devoted to this topic in Germany, however, the author concludes that only one theory of intention, that put forward by Professor Wolfgang Frisch, shows any substantial degree of promise.
