Bruising, the result of capillary failure, is a common physical exam finding due to blunt trauma and, depending on location and severity, a potential indicator of abuse. Despite its clinical relevance, few studies have investigated the etiology of capillary failure. The goal of this study was to determine whether capillaries primarily fail under shear stress or hydraulic‐induced tensile stress. An arteriole bifurcating into four capillaries was modeled using ANSYS 14.0 ®. The capillaries were embedded in muscle tissue and a pressure of 20.4 kPa was applied. Any tensile stress exceeding 8.4 × 104 Pa was considered failure. Results showed that failure occurred directly under the impact zone and where capillaries bifurcated, rather than along the line of greatest shear stress, indicating that internal tensile stress is likely the primary mode of capillary failure in bruising. These results are supported by the concept that bruising can occur via blunt trauma in which no shearing lacerations occur. 相似文献

The present study considered risk factors associated with suicidal ideation and the likelihood of a suicide attempt in a sample of 297 homeless and runaway youth from four Midwestern states. It was hypothesized that sociodemographic characteristics, family factors, suicide exposure, street factors, externalizing behavior, and internalizing behavior would be related to suicidal ideation and to the likelihood of a suicide attempt. It was also hypothesized that suicidal ideation would mediate the relationship between the other predictor variables and the likelihood of a suicide attempt. Over half the sample (53.9%) endorsed some level of suicidal ideation, and over one quarter (26.3%) attempted suicide in the year prior to the interview. Univariate and multivariate results indicated that sexual abuse by a family member, knowing a friend who attempted suicide, drug abuse, and internalization were highly related to suicidal ideation. In the absence of suicidal ideation, sexual abuse, sexual victimization while on their own, and internalization were highly related to the likelihood of a suicide attempt. Finally, the hypothesized mediating effect was found for both sexual abuse and internalization. 相似文献

In this note I examine the concept of sacred values. Some commentators have recommended avoiding the question or postponing negotiations until other issues have been settled, whereas others have suggested that few sacred values cannot be rendered into some form of trade‐off (i.e., they are pseudosacred). Here, I follow Scott Atran and Robert Axelrod and argue that ritual and the sacred can be an important component of negotiation and, when addressed effectively, have great potential to break impasse. I first examine the notion of the sacred and its near synonyms, the priceless and the intrinsically valuable. I then look at the issue of valuing life and show that although society places limits on lives as a matter of policy, it paradoxically funds heroic acts, such as mine rescues, which defy economic justification. These acts turn out to fulfill an important symbolic and ritualistic function. Finally, I draw out three implications of the framework for negotiators: negotiators should engage in some form of values clarification among the parties, material compromise by one party does not necessarily indicate that that party's values were not ultimate or that these have been relinquished, and considerable weight should be placed on ritualistic and symbolic gestures with regard to values. 相似文献

This study examined the impact of prior personal or vicarious experience with the criminal justice system on sentencing attitudes.
Existing research on sentencing attitudes has examined factors such as race, gender, income level, political affiliation,
and education level, but few research studies have focused on actual contact with the criminal justice system and its influence
on perceptions of sentencing as either too harsh or too lenient. The current study utilized data collected by the Roper Center
for Public Opinion Research. Over 1,500 respondents were surveyed nationwide in 2006 regarding sentencing attitudes. Logistic
regression analysis was utilized to assess the impact of factors of interest on sentencing attitudes. Results indicated that
individuals who had been charged with a crime (personal experience), or who had an immediate relative or close friend who
had been charged (vicarious experience), were more likely to perceive the criminal justice system as too harsh, regardless
of race/ethnicity. 相似文献

Two studies tested the impact of an alibi witness’s relationship to a defendant on the perceived credibility of that witness.
In the first study, 291 mock jurors estimated the frequency with which individuals would invent alibis, the frequency they
themselves would do so, and the frequency of interpersonal contact among individuals of varying relationships. The degree
of relationship between an alibi witness and a defendant remained a predictor of witness credibility when contact frequency
was controlled. In the second study, 512 mock jurors were randomly assigned to case scenarios. Skepticism toward witnesses
who are biologically or affinally related to a defendant was greater than skepticism toward a socially linked witness. Both
studies supported predications from kinship theory and reciprocal altruism. 相似文献

The members of the U.S. Supreme Court have different ideas about what constitutes good judicial policy as well as how best to achieve that policy. From where do these ideas originate? Evolutionary psychology suggests that an answer may lie in early life experiences in which siblings assume roles that affect an adult's likely acceptance of changes in the established order. According to this view, older siblings take on responsibilities that make them more conservative and rule‐bound, while younger ones adopt roles that promote liberalism and greater rebelliousness. Applying this theory to the Court, I show that these childhood roles manifest themselves in later life in the decisions of the justices. Birth order explains not only the justices’ policy preferences but also their acceptance of one important norm of judicial decisionmaking, specifically their willingness to exercise judicial review. 相似文献
