A new method for casting three-dimensional shoeprints and tire marks with dental stone

Dental stone is used as the major material for recovering three-dimensional shoeprints and tire tracks from crime scenes. The procedure for using dental stone sparsely changed over the years. There are two common methods for mixing dental stone: (i) a premeasured amount of dental stone is put in a zip-lock bag to which water is added, and (ii) the water and dental stone are mixed in a bucket. We suggest a novel rapid and efficient method of mixing dental stone and water in a bottle. These methods were compared at equal conditions. The parameters measured were the number of air bubbles, the strength of the cast, the ease of use, and the sharpness and quality of the accidental characteristics present in the cast. The proposed bottle method has the advantages of both the bucket and the zip-lock methods hence it combines strength, sharpness, high quality, and ease of use.     

A Longitudinal Family-Level Model of Arab Muslim Adolescent Behavior Problems

Arab-American Muslim adolescents in immigrant families face a number of challenges that put them at risk for behavior problems. This study of Arab-American Muslim Adolescents and their relatively recent immigrant mothers tested a longitudinal family-level model of adolescent behavior problems. Mother-adolescent dyads (N = 530) completed measures of maternal and adolescent stressors, active and avoidance coping, and social support; maternal distress; quality of mother–child relationship; and adolescent behavior problems at Time 1 and approximately 18 months later. The youth were between the ages of 11 and 15 years at Time 1 and 48.7% were girls. Longitudinal analyses were conducted using latent change modeling with change scores from Time 1 and Time 2 data. Social support facilitated active coping for both mothers and adolescents. Although maternal avoidance coping mediated maternal stressors and its effect on maternal distress, maternal stressors and maternal distress were not related to adolescent behavior problems. The only factor mitigating the effects of adolescent stressors on adolescent behavior problems was the quality of the mother–child relationship. These findings suggest that adolescents are insulated from maternal stress and distress as long as there is a good mother–child relationship.     

Factors Influencing the Filing of Complaints,Their Investigation,and Subsequent Legal Judgment in Cases of Sexual Assault

In Geneva, examination of victims of sexual assault is performed by a gynecologist and a medical examiner. 48% of the victims file a complaint and we wanted to investigate the factors leading to file a complaint, those leading the Prosecutor to go to trial, and those influencing a conviction. Between 2006 and 2012, 676 victims of sexual assault were investigated (averaged age 26 year, mean 22). Information on injuries, perpetrators, and circumstances of the assault was collected and analyzed. The attacker being the ex‐spouse or a friend and the presence of semen were factors leading to file a complaint. The assailant being a family member or ex‐spouse and the presence of genital/anal lesions were factors influencing the Prosecutor. The presence of nongenital lesions, the assailant being known by the victim, influenced conviction. This study shows that the medical examiner plays a vital role in the investigation of cases of sexual assault.     

The identification of stolen paintings using comparison of various marks

Several oil paintings, suspected of being stolen, were found in the possession of an art dealer in Tel-Aviv, Israel. The authors were asked to determine if these paintings were the stolen ones, based on photographs, stretchers, and frames submitted by the alleged owners in France. A physical match was found between two of the questioned paintings and two stretchers. Another painting was identified as being previously affixed to the original frame by several nails. The fourth painting was identified as being the one photographed by the alleged owner. This identification was done by comparing micro-topography marks revealed by the illumination conditions of that photograph and of the questioned painting.     

Maternal cigarette smoking during pregnancy and life-course-persistent offending

Evidence exists documenting the relationship between maternal cigarette smoking and offspring criminal behavior. Although efforts to understand this relationship in a theoretical framework have only recently emerged, attempts made have been grounded in Moffitt's developmental taxonomy of antisocial behavior. Specifically, maternal cigarette smoking is generally viewed as a potential disruption in the offspring's neuropsychological development, which is subsequently associated with life-course-persistent offending. Using a birth cohort of 987 African Americans, the authors extend previous research by empirically assessing, prospectively, the link between maternal cigarette smoking and life-course-persistent offending while using different operationalizations of Moffitt's offending categorization. The authors' findings offer some support for the relationship between maternal cigarette smoking and life-course-persistent offending, which is dependent on how this concept is operationalized.     

The Future Israeli-Palestinian Relationship

In this concept paper, the Joint Working Group on Israeli‐Palestinian Relations‐a group of influential Palestinians and Israelis that has been meeting periodically since 1994 to discuss final‐status issues in the Israeli‐Palestinian negotiations‐explores the future relationship between the two societies after the signing of a peace agreement. The paper considers a relationship based on total separation between the two societies and states as neither realistic nor desirable. Instead, it envisages a future relationship based on mutually beneficial cooperation in many spheres, conducive to stable peace, sustainable development, and ultimate reconciliation. The basis for such a relationship must be laid in the process and outcome of the final‐status negotiations and in the patterns of cooperation established on the ground. Efforts at cooperation and reconciliation cannot be pursued apart from their political context. The paper argues that the only feasible political arrangement on which a cooperative relationship can be built is a two‐state solution, establishing a genuinely independent Palestinian state alongside of Israel. The resolution of final‐status issues must be consistent with the sovereignty, viability, and security of both states. The paper then proceeds to describe several models for the relationship between the two states and societies. It advocates a model of close cooperation, but proposes that this relationship be built in stages. The scope and speed of expanding and institutionalizing cooperative activities must be determined by experience‐by the extent to which such activities meet the needs of both parties, enhance mutual trust, and reduce inequalities between the parties. Finally, the paper discusses three avenues for promoting a cooperative relationship based on equality, reciprocal benefit, and mutual trust and respect: the development of functional ties and civil‐society institutions across national borders; programs directed toward attitude change and stereotype reduction; and efforts to close the economic and political gap between the two societies.
