"The red zone": temporal risk for unwanted sex among college students

The "red zone" usually refers to the first few weeks of the first semester at college, when female students are believed to be at greatest risk for experiencing unwanted sex. We tested this notion using data from a survey study of 207 first-and second-year students (121 women, 84 men) at a small, liberal arts university. Results demonstrated only one significant elevation in incidence rates of first- and second-year women's unwanted sexual experiences (sexual touching, attempted and completed anal, oral, and vaginal sex), between the end of the first month and fall break (mid-October) during the second year at school. Previous research and local information about the relevant behaviors of sorority and fraternity members is discussed in light of these findings to provide heuristic material for further empirical testing. Because risk may involve both temporal and situational factors, systematic collection and dissemination of local data are recommended.     

Government procurement law and hacking technology: The role of public contracting in regulating an invisible market

This article considers the purchasing of hacking technology by governments and the role of government procurement processes in regulating the hacking market and reducing risks to the buyer. While the proliferation of hacking technology for government actors has led to various proposed solutions for accountability, little consideration has been given to public purchasing of this technology. This article explores whether public contracting processes could be used to help minimize the risks that arise from the use of government hacking technology, and, if so, the types of contractual clauses and institutional supports that might be useful to achieve that goal. In exploring this issue, this article considers theories of government by contract and the publicization of the private sector. These theories posit that public contracting can be used as a vehicle to impose public considerations—for example, certain policy goals—on the private sector. It argues that requirements of transparency and accountability that inhere on the public sector could be transferred in part to the private sector through the vehicle of a public contract and explores how public contracts for government hacking technology could be structured in order to reduce risks posed by the use of this technology.     

Metric assessment of the "mastoid triangle" for sex determination: a validation study

Recently, a metric approach to skeletal sex determination was published by Paiva and Segre which is based on the summation of two triangular areas defined by three distinct craniometric landmarks: Porion, Mastoidale, and Asterion. According to the authors, values for the total triangle > or =1447.40 mm(2) are characteristic for male crania, while values < or =1260.36 mm(2) are indicative of female skulls (95% confidence). In order to evaluate the method's validity, two sex- and age-documented samples of different provenience were analyzed (N=197). The results show that while the indicated measurements display significant sex differences, the technique is of little practical meaning where a single individual must be independently classified. It is hypothesized that differences in the expression of sexual dimorphism as well as a population-specific variability of the asterion location undermine the value of the mastoid triangle as a sex determinant.     

The theory of postmortem rigidity: the history and an original concept

The original theory of postmortem rigidity has been developed and substantiated based on the concept of postmortem muscular contracture. It is postulated that the unrestricted growth of Ca2+ concentration in myoplasm of contractile cells during the immediate postmortal period brings the actin-myosine complex to the force generation state without subsequent relaxation.

The juvenile sex offender: The effect of employment on offending

PurposeIn many countries, sex offenders are treated as a special group of offenders, requiring special criminal justice responses and treatment modalities, presuming they are at high risk of re-offending. These special measures limit them in entering adult roles, especially employment. At the same time, such adult roles have been found to reduce offending risk in general offenders. We aim to investigate whether employment reduces offending rates in juvenile sex offenders' (JSO).MethodUsing longitudinal data on a Dutch sample of 498 JSO, we investigate employment and offending careers in JSO. A hybrid random effects model is used to investigate within-individual changes of employment quality and employment stability on offending. We also investigated whether the effects differ for child abusers, peer abusers and group offenders, who have different background profiles and for whom employment effects could be less.ResultsWe first show that JSO enter the labor market at relatively young ages, with stagnating participation rates from age 25 on, and numerous and short-lived employment contracts. In spite of these fractured careers, employment is associated with a decrease in offending. We found no difference for offender types in the effect of employment on offending.ConclusionsWe conclude that for JSO, employment decreases offending. Policies aimed at guidance towards employment, or the inclusion into conventional society, may be effective for JSO.     

The case for regulating collaborative reproduction: a children's rights perspective

There is little regulation of collaborative reproduction--the use of the eggs, sperm, or embryos of a third party to create a child biologically unrelated to at least one intending parent. This Article argues that the dearth of regulation should be assessed from a children's rights perspective and accordingly adjusted. After examining the effects of the experimental reproductive technologies, it concludes that traditional family law preferences and policies are undercut by the deliberate creation of collaboratively reproduced children. The lack of regulation might stem from constitutional protection afforded parents in the right of privacy and substantive due process cases. The author, however, contends that collaborative reproduction implicates the rights of children and requires a separate balancing of rights not contemplated in other cases. Collaborative reproduction also requires regulation because of its spill over effects on the acceptability of cloning. The Article concludes by offering several possible regulatory responses to the problems posed by collaborative reproduction.     

Consistency in crime site selection: An investigation of crime sites used by serial sex offenders across crime series

PurposeKnowing sites used by serial sex offenders to commit their crimes is highly beneficial for criminal investigations. However, environmental choices of serial sex offenders remain unclear to this date. Considering the challenges these offenders pose to law enforcement, the study aims to identify sites serial sex offenders use to encounter and release their victims and investigate their stability across crime series.MethodsThe study uses latent class analysis (LCA) to identify victim encounter and release sites used by 72 serial sex offenders having committed 361 sex offenses. Additional LCA are performed to investigate the stability of these offense environments across offenders' crimes series.ResultsDistinct profiles of crime sites that are recurrent across crime series are found, suggesting that serial sex offenders present a limited diversity of victim encounter and victim release sites. Encounter sites representative of longer crime series are also identified. Specifically, the use of sites known to "attract" potential victims decreases over series and offenders become more risk-taking in regard of sites used to encounter their victims.ConclusionsThe study identifies patterns of site- selection for the victim encounter and release in cases of serial crimes. Implications for crime linkage and police investigations strategies are discussed.     

Harnessing technology: The workers' stake

Innovation has both potential benefits and possible destructive effects when viewed by the worker. This article presents some of the thinking of the AFL/CIO concerning this issue. Several methods to ease the human cost of industrial innovation are discussed. Early warning systems, income maintenance, transfers and relocation are suggested as helpful. The point is made that the best way to stimulate innovation is to make sure the economy of the nation is at full employment, with strong consumer demand and high utilization of national resources. A discussion is presented about the shift in technology caused by the expansion of the multinational corporations. This technology shift has a significant impact on our economy and should be understood better and possibly controlled. Another major point of the paper deals with safety and safety regulations as they relate to innovation and to the worker.
