The aim of this study was to determine whether polyurethane (PU) foam fragments from different sources could be discriminated from each other. Low and high power microscopy was used to determine whether or not foam fragments were distinguishable from each other under various lighting conditions. Once similar foam fragments were declared microscopically indistinguishable, the visible range microspectrophotometer was highly competent in further distinguishing the spectral characteristics in various fragments from each other. Foam fragments from the same source were shown to display no microscopical or chemical variation. Conversely, it was possible to make clear distinctions between foam fragments from different sources. 相似文献

This study assessed the associations of characteristics of domestic violence incidents with clinically significant levels
of traumatic symptoms and behavioral problems in a socio-economically and ethnically mixed sample of 687 children participating
in a community-service program for children witnessing violence. Study predictors included child/family demographic characteristics,
type and chronicity of exposure, and child’s perceptions of control over the event and threat to personal safety. Outcomes
consisted of traumatic symptoms and behavior problems. Results showed that perceived threat and control were associated with
greater odds of clinically significant levels of several trauma symptoms (and behavior problems in the case of perceived threat)
after adjusting for effects of demographic factors and violence characteristics. Child co-victimization increased odds of
reaching clinically significant levels of traumatic symptoms compared to children who witnessed the event but were not victimized.
Female sex and White ethnicity increased odds of specific trauma symptoms and behavior problems. Increasing age reduced odds
of some trauma symptoms. Associations between predictors and one outcome measure did not generalize across the other outcome
measure. Implications of study findings, and directions for future research are discussed. 相似文献

Childhood obesity is in important respects a result of legal policies that influence both dietary intake and physical activity. The law must shift focus away from individual risk factors alone and seek instead to promote situational and environmental influences that create an atmosphere conducive to health. To attain this goal, advocates should embrace a population-wide model of public health, and policymakers must critically examine the fashionable rhetoric of consumer choice. 相似文献

Recent interest in the construct of motivation to change among male perpetrators of intimate partner violence (IPV) has led
to development of two self-report measures of this construct: the University of Rhode Island Change Assessment for Domestic
Violence (URICA-DV; Levesque et al. 2000) and the Safe at Home Inventory (SAH; Begun et al. 2003). We examined the internal
structure of these instruments using confirmatory and exploratory factor analyses in a sample of 199 male IPV perpetrators
waiting to begin court-mandated batterer intervention programs. Results indicated that the scales had adequate internal consistency.
However, using confirmatory factor analyses, the hypothesized structural models of each instrument fit the data poorly. Subsequent
models suggested by a series of exploratory factor analyses failed to improve model fit substantially for both scales. For
the URICA-DV, a 3-factor model including items from the Precontemplation, Contemplation, and Action subscales fit the data
adequately. No acceptable model fit could be found for the SAH. Intercorrelations among similar subscales across the two inventories
suggested only a modest degree of intercorrelation (r’s = 0.16–0.52), and a factor structure more dependent on scale of origin than item latent content, suggesting that the scales
assess different facets of the readiness to change construct. These results suggest that before the stages of change construct
can be fully applied to the IPV area, more research and evaluation are needed on how to accurately assess abuser readiness
to change. 相似文献

A synoptic study of six cases of self-inflicted sharp force injuries is presented, where young, mostly female people had simulated assaults to gain sympathy or other personal advantage. The morphological distinctives of simulated assault wounds from such of real assault are worked out and the common situative and motivative background is cleared up. 相似文献
