Incidence of auditory ossicle luxation and petrous bone fractures detected in post-mortem multislice computed tomography (MSCT)

As the auditory ossicles are difficult to display without harming them in conventional autopsies, lesions of these minute bones and the ossicular chain are regularly missed. In this study, the method of choice in clinical medicine for the examination of such lesions, namely multislice computed tomography, was applied to 100 corpses.The hereby obtained results regarding ossicle luxation and petrous bone fracture indicated that the lesions were not dependant on the amount, but rather on the type of energy inflicted to the head.

Policy influences on community trail development

This study explores processes and policies that facilitate the development of community trails. With funding from Active Living Research and the research framework of the Physical Activity Policy Research Network (PAPRN), we conducted a multiple-site case study. A total of six trails in Hawaii, Massachusetts, Missouri, North Carolina, South Carolina, and Washington were chosen for study. The goals of this case study were to identify the policy influences on trail development, explore the roles of key players in trail development, and compare and contrast findings from the different trails. Trail development can be a long process. Some of the trails took over a decade to complete because of funding, opposition, and roadblocks in the form of design standard policies. Work in trail development requires a team of many players, and it is necessary to balance their varied motives to accomplish a shared overall goal. Foresight through the master planning process is also a vital component of successful trail development. Finally, community involvement is key. Communities contemplating trail development should explore the effects of policy on the trail projects reported here to proactively identify potential influence.     

Police response to domestic violence: making decisions about risk and risk management

Assessing and responding to risk are key elements in how police respond to domestic violence. However, relatively little is known about the way police make judgments about the risks associated with domestic violence and how these judgments influence their actions. This study examines police decisions about risk in domestic violence incidents when using a risk assessment instrument. Based on a sample of 501 risk assessments completed by police in Australia, this study shows that a limited number of items on the risk assessment instrument are important in police officers' decisions about risk. Statistical analyses show that the victim's level of fear contributes to police officers' judgment on the level of risk and their decisions on which risk management strategy should be used. These findings suggest that research on police responses to domestic violence needs to pay greater attention to situational dynamics and the task requirements of risk-based decision making.     

A DNA-based approach for the forensic identification of Asiatic black bear (Ursus thibetanus) in a traditional Asian medicine

Attempts to prevent illegal trade in bile and gallbladders from Asiatic black bears, Ursus thibetanus, are hampered by difficulties associated with identifying such items. We extracted DNA from bile crystals of unknown species origin and generated partial cytochrome b (cyt b) sequences using either universal primers (positioned in conserved regions of cyt b), or primers designed on existing U. thibetanus sequences (UT). Species origin was determined by aligning resolved sequences to reference sequence data. The universal primers were unsuitable for U. thibetanus identification when multiple species templates were present in the samples. The UT primers amplified U. thibetanus DNA from all sample extracts, including those containing mixed species templates. The amplified fragment can distinguish U. thibetanus from the most closely related species, U. americanus, a distinct advantage of DNA sequencing over the methods currently used to analyze suspected U. thibetanus bile.     

Sexual dimorphism in America: geometric morphometric analysis of the craniofacial region

One of the four pillars of the anthropological protocol is the estimation of sex. The protocol generally consists of linear metric analysis or visually assessing individual skeletal traits on the skull and pelvis based on an ordinal scale of 1-5, ranging from very masculine to very feminine. The morphologic traits are then some how averaged by the investigator to estimate sex. Some skulls may be misclassified because of apparent morphologic features that appear more or less robust due to size differences among individuals. The question of misclassification may be further exemplified in light of comparisons across populations that may differ not only in cranial robusticity but also in stature and general physique. The purpose of this study is to further examine the effect of size and sex on craniofacial shape among American populations to better understand the allometric foundation of skeletal traits currently used for sex estimation. Three-dimensional coordinates of 16 standard craniofacial landmarks were collected using a Microscribe-3DX digitizer. Data were collected for 118 American White and Black males and females from the W.M. Bass Donated Collection and the Forensic Data Bank. The MANCOVA procedure tested shape differences as a function of sex and size. Sex had a significant influence on shape for both American Whites (F = 2.90; d.f. = 19, 39; p > F = 0.0024) and Blacks (F = 2.81; d.f. = 19, 37; p > F = 0.0035), whereas size did not have a significant influence on shape in either Whites (F = 1.69; d.f. = 19, 39; p > F = 0.08) or Blacks (F = 1.09; d.f. = 19, 37; p > F = 0.40). Therefore, for each sex, individuals of various sizes were statistically the same shape. In other words, while significant differences were present between the size of males and females (males on average were larger), there was no size effect beyond that accounted for by sex differences in size. Moreover, the consistency between American groups is interesting as it suggests that population differences in sexual dimorphism may result more from human variation in size than allometric variation in craniofacial morphology.     

Persistence and renewal: the German Left Party's journey from outcast to opposition

This article examines electoral support for the German Left Party (Die Linke) at the 2013 Federal election. It focuses on two substantive issues. The first is that whilst studies have commonly linked the party's support to political culture, the party has modernised and it is unclear how this has influenced its support. The second is that the election was held amidst the fallout of the global financial crisis and thus enables us to test if the party benefitted from economic adversity. Using multivariate logistic regression models, these issues are investigated at the individual-level using data from the German Longitudinal Election Study. The results demonstrate that the party's support is steeped in political culture, but with important east–west variation. Further, there is no evidence that the party attracted support from economically anxious voters. These findings present a basis for broader reflections on the party's influence on the contemporary political landscape.     

When Do Displaced Persons Return? Postwar Migration among Christians in Mount Lebanon

Under what conditions will forcibly displaced persons return to their original homes after wars end? We draw on theories of labor migration to show that even displaced persons who have positive feelings toward their original location may nevertheless choose to return as regular visitors rather than permanent residents unless the location offers attractive economic opportunities. Furthermore, we argue that violence can create negative emotions not only toward geographic locations of bloodshed but also against its perpetrators. After ethnic wars, the displaced may be unwilling to return to intermixed locations, exacerbating ethnic separation. We study postwar migration among Lebanese Christians displaced during the 1980s and identify economic conditions using exogenous price shocks for olive oil, a major local export. Among policy implications for economic reconstruction and transitional justice, our most important insight is that sometimes we should help the displaced in their new location rather than induce permanent return to their old homes.
