Fatalities Due to Indigenous and Exotic Species in Florida

Florida's climate is suitable for many potentially hazardous animals, including both indigenous and exotic species, which are frequently kept as in zoos or as pets. This has resulted in many unforeseen fatal encounters between animals and the ever expanding human population. While the literature and knowledge pool for more common types of deaths referred to medical examiner/coroner's offices is abundant, the appreciation of wildlife and exotic pet‐related deaths is far less widespread. We report seven animal attack‐related deaths that occurred in Florida. The inflicted injuries included blunt and sharp force injuries, asphyxia, drowning, and envenomation. The underlying cause of death, however, was always a result of the human/animal interaction and in many cases related to human error and failure to appreciate the potentially dangerous behavior of nondomesticated species. These cases illustrate the varied circumstances and pathophysiologies associated with deaths due to indigenous and exotic species and the importance of the multidisciplinary approach in the medicolegal investigation of these cases.     

Developmental validation of RSID™-Semen: a lateral flow immunochromatographic strip test for the forensic detection of human semen

Abstract: Tests for the identification of semen commonly involve the microscopic visualization of spermatozoa or assays for the presence of seminal markers such as acid phosphatase (AP) or prostate‐specific antigen (PSA). Here, we describe the rapid stain identification kit for the identification of semen (RSID?‐Semen), a lateral flow immunochromatographic strip test that uses two antihuman semenogelin monoclonal antibodies to detect the presence of semenogelin. The RSID?‐Semen strip is specific for human semen, detecting <2.5 nL of semen, and does not cross‐react with other human or nonhuman tissues tested. RSID?‐Semen is more sensitive with certain forensic evidence samples containing mixtures of vaginal secretions and semen than either of the commercially available PSA‐based forensic semen detection tests or tests that measure AP activity that were tested in parallel. The RSID?‐Semen kit also allows sampling a fraction of a questioned stain while retaining the majority of the sample for further processing through short tandem repeat analysis.     

The Narmada River Project: Toward a feminist model of women in development

A number of competing models of women in development have been vying for the allegiance of feminist scholars concerned with gender equity in the Third World. This article compares the merits of the liberal integration model, the marginalization model, the capitalist exploitation model, and the socialist feminist model in assessing the probable consequences of a mega-development project for women. Using the Sardar Sarovar Project on the Narmada River in India as a case study, the essay contrasts the outcomes projected by each model in order to explore the play of gender in Third World societies and in development policies. In addition, applying these competing models to an on-going development project illuminates limitations in each model which must be overcome if the goal of a feminist model of women in development is to minimize the harm done to women by development and to empower women of the Third World.     

Rapid screening of selected organic explosives by high performance liquid chromatography using reversed-phase monolithic columns

This study presents the rapid screening of various high grade explosives by high performance liquid chromatography (HPLC) with monolithic stationary phases. Two gradient methods were developed, the first for quantitative analysis of eleven explosives: HMX; RDX; Tetryl; TNT; 2,3-DNT; 2,6-DNT; 3,4-DNT; 2-NT; 3-NT; 4-NT; and PETN in under 14 min. The second method separated seven explosives in under two min and is suitable for rapid screening to determine the presence of specific and/or class of explosive. The rapid screening methods were successfully applied to soils spiked with known amounts of target explosives. This technology showed excellent potential for forensic explosives detection and analysis.     

Negotiating group decisions

Conclusion The research on negotiations, coalition formation, and group decision making suggests numerous ways to improve the quality of group decisions ranging from selection and training of group members, development of norms to maximize the amount of relevant information considered by the group, and the selection of an approach to integrate that information. In thinking about managing the process, it is useful to consider what may be done at the time a task force or team is formed, what needs to be done prior to decision making, and what may be done to integrate information and preferences to make high quality decisions. Table 5 organizes the ideas discussed in this article by stages.An interesting question is how overtly a group leader or member may act in managing this process. Groups themselves do not seem to engage in much deliberate planning. They often jump into their tasks only to back off and plan when they find themselves hopelessly frustrated, such as in the MIS task force in our example. Most groups do not have the luxury of team-building training—learning techniques to reach high quality group decisions in a simulated environment. So, it is often up to individual group members to direct the group to use processes that will produce high quality decisions. Jeanne M. Brett is the DeWitt W.

Latent Print Proficiency Testing: An Examination of Test Respondents,Test-Taking Procedures,and Test Characteristics

Proficiency testing is a key component of quality assurance programs within crime laboratories and can help improve laboratory practices. However, current proficiency testing procedures contain significant limitations and can be misinterpreted by examiners and court personnel (Garrett & Mitchell, 2018). To evaluate some of these limitations, we surveyed latent print examiners (n = 198) after they completed a Collaborative Testing Services, Inc. proficiency test. Additionally, we evaluated test performance and used a quality metric algorithm to evaluate the quality of test prints. Results do not suggest that respondents are dissimilar to the broader examiner population, although they may engage in different behaviors when completing tests versus casework. Findings show that proficiency testing contains prints of high quality and is perceived as both relatively easy and representative of casework. The test discriminated between inexperienced and experienced respondents, and verification procedures were largely ineffective in reducing errors. Objective quality metrics may provide a path forward to improving proficiency testing in a measurable manner.     

Social Networks of Homeless Youth in Emerging Adulthood

Little is known about the social networks of homeless youth in emerging adulthood despite the importance of this information for interventions to reduce health risks. This study examined the composition of social networks, and the risks and supports present within them, in a random sample of 349 homeless youth (33.4% female, 23.9% African American, 17.7% Hispanic) between the ages of 18 and 24. Social network members who were met on the street were among the most likely to be perceived as engaging in risky sex, as well as to engage in substance use with the youth. Youth were more likely to count on relatives and sex partners for support compared to other network members, but they also were more likely to use substances with sex partners and perceived them as engaging in risky sex. Interventions may need to recognize the importance of intimate relationships during the developmental stage of emerging adulthood by enhancing supportive bonds and reducing substance use and risky sex in these relationships.
