The study explored whether perceived shared experience with a media portrayal could influence various cognitions—such as concern, sense of personal involvement, and desire to learn more—that are important for behavior change. This research used the situational theory of publics in order to evaluate whether perceived shared risk is an antecedent to the factors leading to communication behavior. In general, the findings from this experiment supported the idea that shared risk experience with portrayals in news coverage has the potential to influence problem recognition, involvement recognition, and a new variable that combines information seeking and processing: that of information gaining.  相似文献

Elizabethkingia spp. are common environmental pathogens responsible for infections in more vulnerable populations. Although the exposure routes of concern are not well understood, some hospital-associated outbreaks have indicated possible waterborne transmission. In order to facilitate quantitative microbial risk assessment (QMRA) for Elizabethkingia spp., this study fit dose–response models to frog and mice datasets that evaluated intramuscular and intraperitoneal exposure to Elizabethkingia spp. The frog datasets could be pooled, and the exact beta-Poisson model was the best fitting model with optimized parameters α  = 0.52 and β = 86,351. Using the exact beta-Poisson model, the dose of Elizabethkingia miricola resulting in a 50% morbidity response (LD50) was estimated to be approximately 237,000 CFU. The model developed herein was used to estimate the probability of infection for a hospital patient under a modeled exposure scenario involving a contaminated medical device and reported Elizabethkingia spp. concentrations isolated from hospital sinks after an outbreak. The median exposure dose was approximately 3 CFU/insertion event, and the corresponding median risk of infection was 3.4E-05. The median risk estimated in this case study was lower than the 3% attack rate observed in a previous outbreak, however, there are noted gaps pertaining to the possible concentrations of Elizabethkingia spp. in tap water and the most likely exposure routes. This is the first dose–response model developed for Elizabethkingia spp. thus enabling future risk assessments to help determine levels of risk and potential effective risk management strategies.  相似文献

This study tested a model of the association between maternal and child anxiety that views mother and child attachment beliefs and children's perceptions of maternal control as mediators of the association. The study was conducted with mothers and their children aged 6 to 17 (N = 88). Maternal anxiety was significantly associated with child anxiety and maternal anxious attachment beliefs, whereas child anxiety was associated with maternal anxious attachment beliefs, child insecure attachment beliefs, and children's perceptions of maternal control. Maternal anxious attachment beliefs mediated the association between maternal and child anxiety; however, child attachment beliefs and children's perceptions of maternal control did not. The influence of age and gender is also addressed. The findings are discussed in terms of elucidating the role of attachment beliefs and children's perceptions of maternal control on the association between maternal and child anxiety.  相似文献

L'histoire des peuples autochtones ne figure pas parmi les sujets qui sont traités dans la recherche comparée en génocide. Les auteures examinent l'approche conceptuelle qui a conduit à cette lacune en s'attardant à la terminologie employée et à la distinction qu'impose la typologie du génocide entre génocide idéologique et génocide provoqué par l'expansion d'un groupe aux dépens d'un autre, et en soulignant l'importance qui est rattachée dans cette même typologie à la logique qui motive les régimes coupables de génocide. On examine également la relation qui existe entre génocide des peuples autochtones et ceux des autres peuples, ceci en relation avec trois critères d'analyse, soit la réaction des persécutés, le processus de guérison et la quête de justice. À la suite de cet examen, on démontre qu'une approche plus globale dans l'étude comparée du génocide, approche qui reconnaîtrait l'enver-gure des génocides des peuples autochtones, serait à l'avantage des chercheurs. Enfin, les auteures font remarquer que l'approche foncièrement européenne dans la recherche en génocide a pour effet de circonscrire le débat. The experiences of indigenous peoples have been left outside the framework of comparative genocide research. We first discuss conceptual reasons for this omission, focussing on the role of genocide definitions, ideological vs. developmental distinctions in genocide typologies, and the emphasis in genocide typologies on the motivations of perpetrators. We then illustrate the relation between indigenous genocides and other genocides by examining three important foci of genocide studies: responses, healing and justice. From these comparisons and contrasts, we conclude that a broader comparative approach that acknowledges the importance of indigenous genocides would contribute significantly to genocide studies. Finally, we note that adherence to European world views in genocide studies limits the potential for constructive analysis.  相似文献

Abstract

Occupancy models are used in statistical ecology to estimate species dispersion. The two components of an occupancy model are the detection and occupancy probabilities, with the main interest being in the occupancy probabilities. We show that for the homogeneous occupancy model there is an orthogonal transformation of the parameters that gives a natural two-stage inference procedure based on a conditional likelihood. We then extend this to a partial likelihood that gives explicit estimators of the model parameters. By allowing the separate modeling of the detection and occupancy probabilities, the extension of the two-stage approach to more general models has the potential to simplify the computational routines used there.  相似文献

In this paper we present standardized measures of tenth grade students’ knowledge, attitudes and behaviours concerning sustainable development as those concepts are understood in the United Nations Educational, Scientific and Cultural Organization, and we test the hypothesis that knowledge and favourable attitudes toward SD lead to favourable behaviours. Using a fairly representative random sample of 1,551 tenth grade students from the province of Manitoba, Canada, we crafted 3 indexes. There is a 20-item Index of Knowledge of SD with a good Cronbach alpha = 0.89, a 15-item Index of Attitudes Favourable Toward SD with alpha = 0.84 and a 15-item Index of Behaviours Favourable Toward SD with an alpha = 0.83. About 21% of the variation in our Behaviours Index scores could be accounted for by our Knowledge Index and Attitudes Index scores.  相似文献

Previous research has analyzed how organizations publicly respond in crisis situations. This study addresses a sports crisis, the University of Miami NCAA investigation, as an avenue for exploring how fans become surrogates for organizational crisis responses via the social media entity, Twitter. Using Coombs's (2007) strategy for reputation repair, analysis of 75 highly identified Miami fans with over 42,000 Twitter followers shows that fans were most likely to engage in (a) ingratiation, (b) reminder, (c) attack the accuser, and (d) divert attention as primary methods of coping with the scandal. New methods for reputation repair were also found within the analysis and implications for organizations, academic institutions, sports research, and crisis communication theory are articulated.  相似文献

ABSTRACT

The current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women’s Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996–2015) from the cohort born 1973–1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review.  相似文献

One in three Australian marriages end in divorce, and over half of such divorces involve children. Research indicates that men tend to repartner within 1 to 2 years of a divorce and women within 3 to 5 years. A significant issue for repartnered men is the provision of financial support for children from both their first and second families. Although only 6% of all Australian first family children spend near/equal time (shared care) after divorce with both parents, fathers in Australia are mandated under child support legislation to provide financial support for their first family children, whether they reside with them or not. However, it is argued by this study's nonresidential fathers that the Child Support Agency, when considering the level of financial support for first family children, tends to overlook the needs of second family children, thus creating an advantaged and disadvantaged set of siblings. This finding is reviewed through a distributive justice theory lens. Finally, some future directions for research aimed at exploring the impact of Child Support Legislation on second families are suggested.  相似文献
