The process of online grooming facilitates child abuse and is a threat to young people across the world. This literature review explores the research surrounding how young people are targeted by offenders on the internet. Definitions, prevalence, and characteristics of online grooming are addressed in addition to consideration of child sexual abuse theories and internet behaviors. There are a variety of techniques used by internet groomers to manipulate young people (e.g., flattery, bribes, and threats) and different ways that young people engage in risk taking behavior on the internet (e.g., communicating with strangers online and sharing personal information). While models and typologies can aid professionals in understanding the crime, it is important to acknowledge that internet offenders, victims, and the dynamics between the two are often unique and varied. This is fundamental to the development of effective preventative education for online grooming and abuse. The review concludes that research concerning the online grooming of young people is limited, and calls for further study in this field. 相似文献

Despite the benefits of physical activity for youth with cystic fibrosis (CF) and congenital heart disease (CHD), most are insufficiently active. More information is required on how to facilitate physical activity in these populations. Although there are no studies that provide information about participation in CF and CHD youth from the perspective of parents, the involvement of caregivers may be an important facilitator to physical activity in youth with chronic diseases.
Objective
This qualitative study explored how the parents of youth with CF and CHD experience physical activity, and parents commented on both their own and their child’s physical activity.Methods
Twenty-nine parents from a CHD and CF clinic participated in a semi-structured interview, and a thematic analysis of the transcribed data was undertaken.Results
Parents discussed the numerous benefits and barriers associated with physical activity for both child and self. Role modeling was a critical social process to overcoming barriers. Parents experiences were situated within the broader family context characterized by a prevailing sense of stress and complexity.Conclusion
By illustrating how the parents of youth with CF and CHD understand the role of physical activity in their and their child’s life, this study provides valuable information regarding the development of interventions to increase physical activity among children with CF and CHD. 相似文献494.

Using Hollander's (1958) idiosyncrasy credit theory of leadership as the theoretical backdrop, we examined when and why organizational leaders escape punitive evaluation for their organizational transgressions. In a sample of 162 full-time employees, we found that leaders who were perceived to be more able and inspirationally motivating were less punitively evaluated by employees for leader transgressions. These effects were mediated by the leaders' LMX (leader-member exchange) with their employees. Moreover, the tendency of leaders with higher LMX to escape punitive evaluations for their transgressions was stronger when those leaders were more valued within the organization. Finally, employees who punitively evaluated their leaders were more likely to have turnover intentions and to psychologically withdraw from their organization. Theoretical and practical implications associated with relatively understudied leader-transgression dynamics are discussed. 相似文献

1/f noise has been discovered in a number of time series collected in psychological and behavioral experiments. This ubiquitous phenomenon has been ignored for a long time and classical models were not designed for accounting for these long-range correlations. The aim of this paper is to present and discuss contrasted theoretical perspectives on 1/f noise, in order to provide a comprehensive overview of current debates in this domain. In a first part, we propose a formal definition of the phenomenon of 1/f noise, and we present some commonly used methods for measuring long-range correlations in time series. In a second part, we develop a theoretical position that considers 1/f noise as the hallmark of system complexity. From this point of view, 1/f noise emerges from the coordination of the many elements that compose the system. In a third part, we present a theoretical counterpoint suggesting that 1/f noise could emerge from localized sources within the system. In conclusion, we try to draw some lines of reasoning for going beyond the opposition between these two approaches. 相似文献

This paper aims to cast doubt upon a certain way of analysing prudential value (or good for), namely in the manner of a ‘buck-passing’ analysis. It begins by explaining why we should be interested in analyses of good for and the nature of buck-passing analyses generally (§I). It moves on to considering and rejecting two sets of buck-passing
analyses. The first are analyses that are likely to be suggested by those attracted to the idea of analysing good for in a buck-passing fashion (§II). The second are the buck-passing analyses of good for proposed by John Skorupski (§III), Henry Sidgwick (§IV), and Stephen Darwall (§V). Along the way the paper shows that Michael
Smith’s and Peter Railton’s analyses of other concepts—analyses that could be (and have been) taken to be analyses of good for—are similarly unsuitable as analyses of it. The paper concludes by suggesting that the fact that none of the buck-passing
accounts of good for considered here is satisfactory, coupled with an appreciation of the various problems that a buck-passing analysis of good for would have to avoid, suggests that we should be sceptical about the prospects of finding such an analysis and should look
for one of a different type. 相似文献

Flow is an experience of enjoyment, concentration, and low self-awareness that occurs during active task performance. We investigated associations between the tendency to experience flow (flow proneness), Big Five personality traits and intelligence in two samples. We hypothesized a negative relation between flow proneness and neuroticism, since negative affect could interfere with the affective component of flow. Secondly, since sustained attention is a component of flow, we tested whether flow proneness is positively related to intelligence. Sample 1 included 137 individuals who completed tests for flow proneness, intelligence, and Big Five personality. In Sample 2 (all twins; n = 2539), flow proneness and intelligence, but not personality, were measured. As hypothesized, we found a negative correlation between flow proneness and neuroticism in Sample 1. Additional exploratory analyses revealed a positive association between flow proneness and conscientiousness. There was no correlation between flow proneness and intelligence. Although significant for some comparisons, associations between intelligence and flow proneness were also very weak in Sample 2. We conclude that flow proneness is associated with personality rather than intelligence, and discuss that flow may be a state of effortless attention that relies on different mechanisms from those involved in attention during mental effort. 相似文献

The stress associated with providing care for a spouse diagnosed with Alzheimer's disease can have adverse effects on cardiovascular health. One potential explanation is that chronic caregiving stress may contribute to the development of atherosclerosis. The purpose of this study was to determine whether the duration that one has provided care is associated with the degree of atherosclerotic burden, as measured by carotid artery intima-media thickness (IMT). One hundred and ten Alzheimer caregivers [mean age 74?±?8 (SD) years, 69% female] underwent in-home assessment of carotid artery IMT via B-mode ultrasonography. Data regarding medical history, blood pressure, and multiple indicators of caregiving stress were also collected. Multiple regression indicated that duration of care was positively associated with IMT measured in the internal/bifurcation segments of the carotid artery (β?=?0.202, p?=?0.044) independent of risk factors such as age, gender, body mass index, smoking history, sleep quality, hypertension status, and caregiving stressors. Duration of care was positively associated with IMT in the common carotid artery, but the relationship was not significant. These findings provide more evidence of the link between chronic caregiving stress and cardiovascular disease and indicate that enduring the experience of caregiving over a period of years might be associated with atherosclerotic burden. 相似文献

COPD (chronic obstructive pulmonary disease) is associated with psychological distress for patients as well as their partners. Dyadic coping can be negatively impacted by stressors. This study's objective was to compare the dyadic coping of couples in which one partner suffered from COPD with healthy couples of the same age. A total of 43 complete couples with COPD and 138 healthy couples participated in this pilot study. The surveys were sent by mail. The response rate of the COPD sample was 24.3%. In order to analyze the effect of gender and role (patient vs. partner) on dyadic coping, linear mixed models were calculated. To analyze the effect of gender and group (COPD group vs. normative comparison group) on dyadic coping, two-way analyses of variance were calculated for independent samples. COPD patients and their partners indicated that the patients received more support and were less able to provide support to their partners. This difference was also evident in comparison with the normative comparison group. In addition, couples with COPD perceived higher levels of negative coping and provided a considerably lower assessment of their positive dyadic coping. The dyadic coping of couples with COPD is unbalanced and more negative when compared to that of healthy couples. Interventions aimed at supporting COPD couples should seek to improve couples' dyadic coping in addition to individual coping strategies. 相似文献
