This study examines the perceptions of mental illness identity among a group of emerging adults based on their retrospective experiences with diagnoses and psychotropic medication use during their earlier formative adolescent years. A short questionnaire was administered via online social media platforms to volunteers between the ages of 19 and 30 and who self-identified as having taken psychotropic medication between the ages of 12 and 18 (N = 46). Correlation analysis revealed that several variables were associated with a stronger illness identity, including participant’s happiness with their medication experiences, the belief that medication made them more like their “true” selves, and the belief that their diagnosis was accurate. Content analysis of participant narratives suggested themes related to discontinuation and barriers to adherence. These results contribute to the growing knowledge base around lived experiences of psychiatric medication use and suggest further study on how to advance more informed and compassionate mental health care. 相似文献

An effective business model is the core enabler of any company's performance. Business model innovation is not only becoming more and more important due to increasing and globalizing competition, but also an enormous challenge, both theoretically and practically. Although many managers are eager to consider more disruptive changes to their business model, they often do not know how to articulate their existing or desired business model and, even less so, understand the possibilities for innovating it. One of the steps toward developing more theoretical insight and practical guidelines is the identification of types and the development of a typology of business model innovations. Ten retrospective case studies of business model innovations undertaken by two industrial companies provide the empirical basis for this article. We analyzed the characteristics of these innovations as well as their success rates. The findings suggest that there are indeed various business model innovation types, each with its own characteristics and challenges. 相似文献

We focus on the role that community plays in the continuum of disaster preparedness, response and recovery, and we explore
where community fits in conceptual frameworks concerning disaster decision-making. We offer an overview of models developed
in the literature as well as insights drawn from research related to Hurricane Katrina. Each model illustrates some aspect
of the spectrum of disaster preparedness and recovery, beginning with risk perception and vulnerability assessments, and proceeding
to notions of resiliency and capacity building. Concepts like social resilience are related to theories of “social capital,”
which stress the importance of social networks, reciprocity, and interpersonal trust. These allow individuals and groups to
accomplish greater things than they could by their isolated efforts. We trace two contrasting notions of community to Tocqueville.
On the one hand, community is simply an aggregation of individual persons, that is, a population. As individuals, they have
only limited capacity to act effectively or make decisions for themselves, and they are strongly subject to administrative
decisions that authorities impose on them. On the other hand, community is an autonomous actor, with its own interests, preferences,
resources, and capabilities. This definition of community has also been embraced by community-based participatory researchers
and has been thought to offer an approach that is more active and advocacy oriented. We conclude with a discussion of the
strengths and weaknesses of community in disaster response and in disaster research. 相似文献

We examined factors related to attitudes toward marriage and the importance of having children in both the US and Singapore.
Path analysis indicated that life dissatisfaction leads to materialism, and both of these factors lead to favorable attitudes
toward marriage, which leads to greater desire for children. Further analysis indicated this model was effective in explaining
the difference in desire for children between Singaporeans and Americans, whereby Singaporeans have lower life satisfaction,
higher materialism, and lower attitudes toward marriage and children. Materialistic standards of success were also related
to the emphasis women placed on potential marriage partners’ earning capacity. As Singaporean women had higher materialistic
standards, they also placed higher emphasis on potential mates’ earning capacity. Results suggest a consideration of psychological
variables such as life satisfaction, materialism, and mate preferences may lead to a better understanding of larger-scale
socioeconomic issues, including low fertility rates among developed East Asian countries. 相似文献

We consider the problem of UMVU estimation of a U-estimable function of four unknown truncation parameters based on two independent random samples from two two-truncation parameter families. In particular, we obtain the UMVU estimator of functional, P (Y > X). Also the confidence intervals for some parametric functions are obtained. 相似文献

A system of predictors for estimating a finite population variance is defined and shown to be asymptotically design-unbiased (ADU) and asymptotically design-consistent (ADC) under probability sampling. An asymptotic mean squared error (MSE) of a generalized regression-type predictor, generated from the system, is obtained. The suggested predictor attains the minimum expected variance of any design-unbiased estimator when the superpopulation model is correct. The generalized regression-type predictor and the predictor suggested by Mukhopadhyay (1990) are compared. 相似文献

This paper considers an inventory system with non-instantaneous deteriorating item in which demand rate is a function of advertisement of an item and selling price. This paper aids the retailer in maximizing the total profit by determining optimal inventory and marketing parameters. In contrast to previous inventory models, an arbitrary holding cost rate and arbitrary deterioration rate have been incorporated to provide general framework to the model. First, a mathematical model is formulated and then some useful theoretical results have been framed to characterize the optimal solutions. The necessary and sufficient conditions for the existence and uniqueness of the optimal solutions are also derived. An algorithm is designed to find the optimum solutions of the proposed model. Numerical examples are included to illustrate the algorithmic procedure and the effects of key parameters are studied to analyze the behavior of the model. 相似文献
