Developing and Testing a Soil Property Database for Forensic Applications in Southern California

The research sought to develop and test a forensic database of surface soil variability within previously mapped geologic and soil units in southern California. This type of database could be used to link suspects to crime scenes or determine source locations of soil sample evidence. Variability was evaluated using (i) color, (ii) magnetic susceptibility, and (iii) particle‐size distribution. Soil properties were analyzed for their ability to discriminate source areas using stepwise discriminant analysis. The percent correct predictions for geologic unit groups ranged from 30% to 100%. A blind study experiment matched four of the 18 samples to their unit of origin with the first choice by stepwise discriminant analysis, and eight were matched as second and third choices. The probability of selecting the appropriate unit of origin increased by 54% over random chance and eliminated as much as 99% of the field area as a potential search location.     

The role of religious coping on problematic alcohol consumption by police officers

Problematic alcohol consumption by police officers is well documented in the literature. It also shows that critical incident stress is correlated with this behavior. A separate body of research indicates that religious coping exerts a moderate protective effect on various types of problematic behavior, including problematic alcohol consumption. We merge these literatures in an effort to determine if religious coping reduces problematic alcohol consumption by police officers and whether it mitigates the positive relationship between critical incident stress and problematic drinking. Data from the Police Stress and Domestic Violence in Police Families in Baltimore, Maryland, 1997–1999 are analyzed to examine these propositions (n = 1004). Results indicate that police officers with higher levels of religious coping were in fact less likely to report problematic alcohol consumption. However, religious coping did not mitigate the positive relationship between critical incident stress and problematic alcohol consumption. The implications of our findings and suggestions for future research are discussed.     

Nova Scotia renews its HIV/AIDS strategy

On 1 December 2003, after a five-year process of consultation and planning, Nova Scotia embarked on a new HIV/AIDS strategy. It replaces the first strategy, launched a decade earlier. The renewed strategy is meant to promote collaborative action on the determinants of vulnerability to HIV infection and on the capacity of people living with HIV/AIDS to achieve optimal health and quality of life.     

An economic approach to social choice — II

There is a formal equivalence between games, societies, and economies. Lindahl equilibrium for a game or society corresponds to competitive equilibrium for the equivalent economy. Results on existence and optimality of competitive equilibrium thus apply to the theory of games and societies. The “core” for a game or society as derived by extension from the core of an economy is “too large” to be interesting. An example illustrates that the α-core may be disjoint from the set of Lindahl equilibria. However, if the power of coalitions to inflict negative externalities is suitably restricted, Lindahl equilibria must be in the α-core.     

Wrongfully Convicted: How the Dutch Deal with the Revision of Their “Miscarriages of Justice”

During most of the twentieth century the very existence of judicial errors was considered an awkward subject in the Dutch legal system. This article considers the change of attitude in recent years. In previous years there was a remarkable self-confidence within the criminal justice system (and in most of the scholarly writings) in doing things the ‘right way.’ After a few warnings from (only partly legally trained) scholars, who became interested in the functioning of the system, and moreover, after a few clear and undeniable cases of judicial error, there was a volte-face in the general feeling amongst both the public and the profession. It is the opinion of the authors that this shift in opinion is historically important. This article therefore intends to draw a picture of the current state of affairs in The Netherlands.
