In forensic intelligence-gathering it would be useful to be able to estimate the size of a perpetrator's foot from a standing bare footprint found at the scene of crime. Currently, the advice is to add a fixed amount to the length of the footprint (typically 1.5 or 2.0 cm), but there is little evidence for this approach. This study used measured footprint and actual foot lengths from 146 participants from the white British student population of a University in the UK. Data were analysed using multiple regression with foot length as the dependent (outcome) variable and footprint length and sex as the independent variable/factor respectively. Sex was not a significant predictor. The regression equation for the best estimate of the foot length is 19.89 + 0.95 × print length ± 8 mm. 相似文献

In this article, we consider the phenomenon of message crimes involving harm to wildlife from a sociological and criminological perspective. Using a case study of dissident Nordic hunters killing protected wolves to send a message to the state agencies responsible for their conservation, we engage philosophically with the question of wildlife victimhood and why interspecies violence is unjustifiable as a mode of political dissent. As an alternative to the species justice perspective in green criminology, we examine how the acts disrespect animals as moral subjects of public communication and frustrate dialogue regarding what is owed to them in terms of political justice. 相似文献

Perflourinated compounds, or PFCs, have been widely used in our industrialized society. Notably, they are used in the manufacture of non-stick coated bakeware and in firefighting foams designed to fight high heat fires. These unregulated chemicals have gotten into surface and groundwater sources of drinking water in locations around the United States and likely the world. Data shows widespread release, particularly near airports and air bases and near industrial production sites.
PFCs cause many health related impacts. Human exposure pathways include perinatal transfer, consuming contaminated water, and consuming contaminated fish. Clean Water Act permitting programs can address their release into waterways. Contaminated site clean-up laws can also be used to remove the source contamination. Granular activated carbon technology can remove most forms of the chemicals from drinking water. The case study of drinking water contamination in Newburgh, New York illustrates the PFC challenge, public reaction, and government response. 相似文献

Adaptive and Maladaptive Gatekeeping Behaviors and Attitudes: Implications for Child Outcomes After Separation and Divorce 下载免费PDF全文
Gatekeeping has been used as a theory and a measure to describe and assess family dynamics within the context of separation and divorce. In this article, we explore adaptive and maladaptive gatekeeping behaviors and attitudes that can affect the other parent's relationship with the child. Implications are presented for connecting adaptive and maladaptive gatekeeping responses to child outcomes of safety, well‐being, and positive parent–child relationships following separation and divorce. We build on the recent attention to gatekeeping as a potential framework within the child custody context. 相似文献

The career stage theory postulates that employees go through different career stages, and each career stage has different effects on various outcomes, such as job satisfaction. There has been empirical support for the career stage theory from other disciplines, but there has been limited research relating to this theory to corrections. To expand the literature, the current study examined whether different career stages were significant predictors of job satisfactions, while including the personal characteristics and the workplace place variables among Texas correctional officers. The results supported the career state theory: job satisfaction was highest during the entry stage (0–2 years), but was lowest during the second career stage (2–5 years). In career stages three (5–15 years) and four (16+ years), job satisfaction rose. Possible interventions that correctional administrators can undertake to encourage job satisfaction from their staff during the second career stage are discussed. 相似文献
