Preferential Selection Independent of Race and Gender: Effects on Self-Evaluations and Newcomer Information-Seeking Behaviors

The current study investigated the effects of an experimentally imposed program of preferential selection on beneficiary self-evaluations and newcomer information-seeking behavior. One hundred-twenty undergraduates were randomly assigned to a classification condition (in which they were informed that they tended to think in either an analytical or abstract manner) and collaborated on a task in groups of three. A fourth participant was introduced into each of these 40 extant groups under either a condition of preferential selection or not. Preferentially selected newcomers were shown to have more positive self-evaluations than their nonpreferentially selected counterparts. The presence or absence of a similar (in terms of thinking style) incumbent moderated the effect of being preferentially selected on the use of specific information-seeking behaviors.     

Bolt Cutter Blade's Imprint in Toolmarks Examination

Bolt cutters are known as cutting tools which are used for cutting hard objects and materials, such as padlocks and bars. Bolt cutter blades leave their imprint on the cut objects. When receiving a cut object from a crime scene, forensic toolmarks examiners can determine whether the suspected cutting tool was used in a specific crime or not based on class characteristic marks and individual marks that the bolt cutter blades leave on the cut object. The paper presents preliminary results of a study on ten bolt cutters and suggests a quick preliminary examination—the comparison between the blade thickness and the width of the imprint left by the tool on the cut object. Based on the comparison result, if there is not a match, the examiner can eliminate the feasibility of the use of the suspected cutting tool in a specific crime. This examination simplifies and accelerates the comparison procedure.     

The Class Characteristic Mark of the H&M Mul‐T‐Lock Picking Tool in Toolmarks Examination

Mul‐T‐Lock is a high security lock cylinder distinguished by the use of a telescoping “pin‐in‐pin”—tumbler design. Picking the Mul‐T‐Lock cylinder with a traditional picking tool is highly complicated because it can get stuck between the inner and outer pins. The H&M Mul‐T‐Lock picking tool was designed to overcome this problem and facilitate the picking of the “pin‐in‐pin” cylinder. The purpose of this research is to determine whether H&M Mul‐T‐Lock picking tool leaves class characteristic mark and whether it can be distinguished from traditional picking tools marks and from regular key marks. It also describes and determines the class characteristic mark left on telescopic pins, its origin, recurrence, and its benefit to the toolmarks examiner. When receiving a Mul‐T‐Lock from a crime scene, a toolmarks examiner can quickly determine whether or not it was picked by an H&M Mul‐T‐Lock picking tool by noticing the class characteristic mark which this typical tool leaves.

Effect of Cutting with an Abrasive Saw on Swarf Composition

Crime scene investigators are often asked to examine swarf from break‐in sites and compare it with swarf found on a suspect. Occasionally, elemental composition of swarf from these two sources does not match. It is generally assumed that cutting metal does not induce changes in chemical composition. However, this study shows that, if a matrix contains iron, chromium, and nickel, composition of swarf produced from cutting the matrix with an abrasive saw may indeed alter. In this study, we cut a stainless steel sheet using a standard cutoff saw. Swarf was sorted and chemically analyzed by EDS/SEM, and the following relationships between chip morphology and modified composition were discovered: elongated chips remained unchanged; changes in the irregular chips appeared to be random, possibly because they are formed in a number of different ways; composition of spherical chips changed with size.     

Gender Differences in Rates of Depressive Symptoms Among Low-Income,Urban, African American Youth: A Test of Two Mediational Hypotheses

The present study tested for gender differences in depressive symptoms in a sample of 622 low-income, urban, African American adolescents. Results indicate that adolescent girls in this sample were significantly more likely to endorse depressive symptoms than were boys. To examine possible explanations for this gender difference, 2 variables were tested as mediators of the relation between gender and depressive symptoms: (1) interpersonal stressors and (2) ruminative coping. Results indicate that ruminative coping, but not interpersonal stressors, mediated the relation between gender and depressive symptoms in this sample. Possible explanations for these findings, in light of the common and unique experiences of low-income, urban youth of color, are explored.     

Methods for estimating medical expenditures attributable to intimate partner violence

This article compares three methods for estimating the medical cost burden of intimate partner violence against U.S. adult women (18 years and older), 1 year postvictimization. To compute the estimates, prevalence data from the National Violence Against Women Survey are combined with cost data from the Medical Expenditure Panel Survey, the Medicare 5% sample, and published studies and with relative risk estimates from published studies. Results are compared and reasons for difference are explored, including the advantages and disadvantages of each approach. Estimates of the medical cost burden of intimate partner violence within the first 12 months after victimization range from USD 2.3 billion to USD 7.0 billion, depending on the method used. Although limited to women victimized in the last year, each method reveals that intimate partner violence imposes a substantial burden on the health care system. Among the approaches, there is no clear gold standard nor any evidence of bias.     

Photographic Image Comparison of Vegetation

Images and videos are common types of evidence in crime scene investigations and laboratory analysis. Images may be taken by the suspect and/or by crime scene investigators and may serve as crucial elements in forensic laboratory analysis. Forensic photographic image comparison is the process of comparing one or more objects or persons in photographs/images when at least one image is known to be related to a crime. The forensic examiner usually compares the images in order to determine whether or not an association between the exhibits in the images can be made. This paper proposes an extension to the currently prevalent photographic image examination method. The extension introduces comparison of landscape and vegetation over time. It is revealed that similarities between images may still be found between the period of time the suspect photograph was taken and the period the crime scene investigator took the photograph from the same area. In this case report, two suspects to be involved in growing a marijuana field were arrested by the police. The forensic experts were asked to examine images taken by the crime scene investigators and to compare them to the images found in the suspects’ phones. They then tried to determine whether the suspects could be linked to the specific locations. While applying techniques derived from morphological comparison methodologies, the plants at the scene provided significant additional information. A tree trunk, branches, and twigs on a hedge in the photographs revealed specific individual characteristics that led the examiner to reach a conclusive decision.
