The increasing pervasiveness of social networks allows users to share purchase behaviors with their online friends. In this study, we examine optimal pricing strategies of a monopolistic firm using an analytical model that accounts for behavioral observational learning in social networks. We show that a seller could potentially control the information available to future customers and induce behavioral observational learning, using an information‐revealing pricing strategy. This result suggests that offering introductory discounts is not always an effective method to boost purchases in social networks. It could prevent the behavioral observational learning that would increase future customers' willingness to pay. 相似文献

Systemic consultation is a form of tertiary case supervision derived from the principles of systemic family therapy. The present study defines the process and outcomes of systemic consultation through the experiences of case managers (CMs) working with people who have an intellectual disability. CMs were invited to present and discuss one of their complex cases with a team of consultants and attend a follow up session 4 to 6 weeks later. Measures of levels of stress, perception of workplace functioning, and workflow information were completed pre and post‐intervention and compared to measures completed by a second group of CMs receiving regular supervision only. After participation in systemic consultation, the networks of people CMs consulted about the case were significantly smaller and they scored significantly higher on a network measure of efficiency of information flow. The CMs experienced lower levels of stress and higher perception of workplace functioning, these differences approached significance. After attending the consultation outcome, themes included a reduced sense of being stuck and stressed, becoming an agent of change and taking perspective. The approach allows CMs space for reflection on practice and new perspectives to be heard. Case management has been under‐represented in documented research and evidence‐based training and supervision models, and is an area in which professional theory appears to be lacking. 相似文献

AbstractThis special issue responds to a growing body of literature at the nexus of studies on queer/sexuality and home/domesticity. It builds on this existing research that seeks to destabilize the heteronormative ideology of home and domesticity, while also opening up this important space—and its constituent practices—for a plurality of identity formations and subjective experiences. Additionally, it addresses calls from lesbian, gay, and queer studies to shift our attention from public spaces and community places to the domestic. This special issue introduction speaks to continuing investigations of how different groups of people seek to creatively construct intimate relations across time, space, and place. Towards this end, the five articles in this special issue are introduced in the context of their contribution to a cross-disciplinary approach to alternative domesticities. 相似文献

In this paper, we propose the class of generalized additive models for location, scale and shape in a test for the association of genetic markers with non-normally distributed phenotypes comprising a spike at zero. The resulting statistical test is a generalization of the quantitative transmission disequilibrium test with mating type indicator, which was originally designed for normally distributed quantitative traits and parent-offspring data. As a motivational example, we consider coronary artery calcification (CAC), which can accurately be identified by electron beam tomography. In the investigated regions, individuals will have a continuous measure of the extent of calcium found or they will be calcium-free. Hence, the resulting distribution is a mixed discrete-continuous distribution with spike at zero. We carry out parent-offspring simulations motivated by such CAC measurement values in a screening population to study statistical properties of the proposed test for genetic association. Furthermore, we apply the approach to data of the Genetic Analysis Workshop 16 that are based on real genotype and family data of the Framingham Heart Study, and test the association of selected genetic markers with simulated coronary artery calcification. 相似文献

Levy (2013) presented examples of discounted stochastic games that do not have stationary equilibria. The second named author has pointed out that one of these examples is incorrect. In addition to describing the details of this error, this note presents a new example by the first named author that succeeds in demonstrating that discounted stochastic games with absolutely continuous transitions can fail to have stationary equilibria. 相似文献

Environmental or genetic influences, or both could account for the increased risk of divorce among the offspring of separated parents. Previous studies have used covariates to statistically control for confounds, but the present research is the first genetically informed study of the topic. The investigation used the Children of Twins Design with twins, their spouses, and their young adult offspring (n = 2,310) from the Australian Twin Registry to test whether selection on the basis of genetic or shared environment factors accounted for part of the intergenerational association. The analyses also controlled for measured characteristics of both parents. The results suggest that both environmentally mediated and genetic risk account for the intergenerational transmission, supporting the roles of both selection and causation. 相似文献

In this article, we explore a few ways in which the age-old impulse to gamble has evolved into a global force. We start out by critically summarizing historical and foundational thinking on gambling in society, and then move into contemporary perspectives on the gambling act. We then focus upon two important actors in these global stages: 'the house' (the businesses that profit from gambling) and 'the players' (the individuals who, for the most part, do not). These explorations highlight the ways in which the globalization of gambling has been characterized by homogenizing trends as well as resistance to homogenization forces. 相似文献
