A probabilistic dealing strategy is proposed which allows all premium brands in an established market to earn nonnegative profits without cooperation. Following the strategy, brands take turns attracting deal-responsive customers. Relative to a reactive competitive strategy, the proposed strategy improves the positions of all premium brands. With use of the strategy, average deal sizes are positively related to a brand's market share, the proportion of quality conscious customers, the proportion of informed customers, the span of regular prices in a market, and the range of customers' acceptable prices.  相似文献

Since the sixties, a number of Western countries have conducted a lot of NPM type reforms in order to improve their public administration (PA). However, more than forty years of NPM type reforms raise questions about whether these reforms consist in an improvement of PA or if alternative theories could find their place in the field of PA reforms. In order to answer these questions, the five main public administration theories (New Public Administration, New Public Management, Public Value Management, New Public Service and New Public Governance) have been selected, and based on an original analysis of their incipits, some guidelines are proposed for practitioners and students in PA.  相似文献

This study examined Family Court of Australia (FCA) judicial determinations in parenting disputes when allegations of child sexual abuse (CSA) are made by an interested party, usually the mother. For the study, 156 published judgments from 2013–2015 were examined to measure how often allegations of CSA are substantiated, suspected to be true, and disbelieved. The characteristics most common in substantiated versus unsubstantiated cases, evidence of abuse presented, and resulting parenting orders were assessed. Findings indicate that, against international comparisons, FCA judges substantiate cases very conservatively, with rates of substantiation much lower than in other studies. Allegations made by mothers against fathers were disproportionately unsubstantiated, as were those which did not fall under the Magellan case management system. Cases where the only evidence of CSA was a child’s disclosure and parent’s allegation were common in both substantiated and unsubstantiated cases, meaning that a lack of other evidence does not preclude a positive finding of risk of CSA by the FCA. Those cases also involving a protection order against the accused were more likely to be substantiated. Confirmation biases and a judicial tendency to err on the side of false negatives are discussed.  相似文献

Objective: To analyze the overlap of nonsuicidal self-injury (NSSI) and suicide-related behaviors (SRB) among college students with regard to demographics, mental health, and coping styles. Participants: Respondents were 572 undergraduate students at a southwestern public university. Methods: Data were collected in 2015. Respondents completed a demographic survey and assessments of NSSI, SRB, internalizing symptoms (ie, anxiety, stress, and depression), aggression, and negative coping strategies. The survey was administered via a Web-based procedure. Results: Women reported more frequent cutting behaviors than men. Endorsement of NSSI was also associated with an increased likelihood of lifetime SRB. A subgroup of students endorsing both NSSI and SRB demonstrated poorer mental health, more negative coping, and self-reported female sex. Conclusions: College healthcare providers may benefit from competency-based training in techniques for the combination treatment of NSSI and SRB, as well as culturally based models of suicide.  相似文献

This article shows that unfavorable economic conditions at graduation decrease the likelihood of a good job‐worker match over a worker's subsequent career. Mismatch is quantified in terms of overeducation by both industry and occupation. The German Socio‐Economic Panel and region‐level unemployment rates from 1994 to 2012 are used. Instrumental variables estimates account for endogenous graduation timing. A single percentage point increase in regional unemployment causes an increase in the probability of overeducation of 1.6–1.7 percentage points for university graduates. Effects for technical tertiary education and apprenticeship graduates are smaller. Labor market entry conditions affect workers for up to 9 years after graduation. (JEL J23, J22, E32, I23)  相似文献

This article explores the continued importance of teaching a diverse curriculum at a time when issues of racial and ethnic equality and diversity have been increasingly sidelined in the political discussion around ‘British’ values and identities, and how these should be taught in schools. The 2014 History National curriculum, in particular, provoked widespread controversy around what British history is, who gets included in this story and how best to engage young people in increasingly diverse classrooms with the subject. The new curriculum provides both opportunities for, and constraints on, addressing issues of racial and ethnic equality and diversity, but how these are put into practice in an increasingly fragmented school system remains less clear. Drawing on the findings of two research projects in schools across England and Wales, this article examines the challenges and opportunities facing teachers and young people in the classroom in the teaching and learning of diverse British histories. We argue that it is not only the content of what children and young people are taught in schools that is at issue, but how teachers are supported to teach diverse curricula effectively and confidently.  相似文献

Analyses of disordered gambling assessment data have indicated that commonly used screens appear to measure latent categories. This stands in contrast to the oft-held assumption that problem gambling is at the extreme of a continuum. To explore this further, we report a series of latent class analyses of a number of prevalent problem gambling assessments (PGSI, SOGS, DSM-IV Pathological Gambling based assessments) in nationally representative British surveys between 1999 and 2012, analysing data from nearly fifty thousand individuals. The analyses converged on a three class model in which the classes differed by problem gambling severity. This identified an initial class of gamblers showing minimal problems, a additional class predominantly endorsing indicators of preoccupation and loss chasing, and a third endorsing a range of disordered gambling criteria. However, there was considerable evidence to suggest that classes of intermediate and high severity disordered gamblers differed systematically in their responses to items related to loss of control, and not simply on the most ‘difficult’ items. It appeared that these differences were similar between assessments. An important exception to this was one set of DSM-IV criteria based analyses using a specific cutoff, which was also used in an analysis that identified an increase in UK problem gambling prevalence between 2007 and 2010. The results suggest that disordered gambling has a mixed latent structure, and that present assessments of problem gambling appear to converge on a broadly similar construct.  相似文献
