Aggressive behavior in pet dogs is a serious problem for dog owners across the globe, with bite injuries representing a serious risk to both people and other dogs. The effective management of aggressive behavior in dogs represents a challenging and controversial issue. Although positive reinforcement training methods are now considered to be the most effective and humane technique to manage the risk of aggression, punishment‐based methods continue to be used. Unfortunately, there has been little scientific study into the various factors influencing whether dog owners choose to use positive reinforcement techniques to manage aggression in their dogs. As such, current understanding of how best to encourage and support dog owners to use these methods remains extremely limited. This article uses a survey methodology based on protection motivation theory (PMT) to investigate the factors that influence owner use of positive reinforcement methods to manage aggressive behavior, in an attempt to understand potential barriers and drivers of use. In addition, the article provides an initial exploration of the potential role of wider psychological factors, including owner emotional state, social influence, and cognitive bias. Findings show that the perceived efficacy of positive reinforcement methods and the perceived ability of owners to effectively implement the technique are both key factors predicting future intentions and current reported use. Future interventions should focus on enhancing owner confidence in the effective use of positive reinforcement techniques across multiple scenarios, as well as helping owners manage their own emotional responses when they encounter challenging situations and setbacks. 相似文献

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations. 相似文献

Interest in understanding how characteristics associated with where people live, in addition to the characteristics of the
people themselves, affect health outcomes has risen sharply in recent years. While much of the research examining this question
focus on teasing apart effects of place and individual on outcomes, less attention has been paid to examining how individuals’
perceptions of where they live may provide some clues to better understanding the influence of place on outcomes. We present
findings from analysis undertaken that incorporate the subjective responses of individuals, residing in three socially contrasting
neighbourhoods, to their local environment. Our first question addressed whether perceptions related to neighbourhood and
city of residence matter to self rated health and quality of life independent of individual characteristics, while the second
question examined whether the perceptions and individual characteristics are modified by the neighbourhood socio-economic
context. Our results show that perceived neighbourhood characteristics, in addition to individual sociodemographic factors,
are significant correlates of self rated health and quality of life. Moreover, we show that the type of perceived neighbourhood
characteristics and the magnitude of their influence on self rated health and quality of life vary depending on whether they
live in high- versus low-socioeconomic status neighbourhoods.

This research was undertaken at a West Coast USA sheltered retirement community where fifteen able elder residents were interviewed about their personal relationships and communication with peers, family and younger people. This paper focuses on respondent's discursive constructions of their relationships with family—particularly adult grandchildren. The analysis shows how respondents' talk about family relationships is largely positive and discusses how respondents build an image of intergenerational solidarity through their accounts of frequency and quality of contact with grandchildren. Some of the ways that intergenerational solidarity is communicated in the context of the interview are: discounting of family problems; cataloguing achievements and talking about grandchildren with pride; demonstrating that they–the elder–are valued; and accounts of how problematic aspects of their relationships are avoided in intergenerational talk. 相似文献

Within the court arena, the credibility and competency of child witnesses often comes under scrutiny and the decision whether a child is considered to be credible or not strongly in?uences whether their evidence will be heard by the court. A child's ability to demonstrate that they understand the difference between truth and lies and the importance of telling the truth is synonymous with competency. Research suggests that many professionals undertaking the task of establishing competency ?nd it very dif?cult, especially with younger children (Aldridge and Wood, 1997, cited in Aldridge and Wood, 1998). This paper describes the process involved in developing an innovative tool for helping professionals assess whether a child understands the difference between truth and lies. The development of the tool arose from the concerns of of?cers from Northumbria Police Force (in the UK) relating to interviews following the protocol of the government's Memorandum of Good Practice (Home Of?ce and Department of Health, 1992) on interviewing child witnesses, and the need to establish whether child witnesses can differentiate between truth and lies. As an example of good practice, The Truth and Lie Story described here has now been included in the Home Of?ce (2002) guidance Achieving Best Evidence in Criminal Proceedings, which is a revision of the 1992 Memorandum of Good Practice.
