We consider whether and under what conditions it is morally illicit to profit from poverty. We argue that when profit counterfactually depends on poverty, the agent making the profit is morally obliged to relinquish it. Finally, we argue that the people to whom the profit should be redirected are those on whom it counterfactually depends.  相似文献

Procrastination is a common self-regulatory failure that can have a negative impact on well-being and performance. However, few clinical trials have been conducted, and no follow-up has ever been performed. The current study therefore aimed to provide evidence for the long-term benefits and investigate predictors of a positive treatment outcome among patients receiving Internet-based cognitive behavior therapy (ICBT). A total of 150 self-recruited participants were randomized to guided or unguided ICBT. Self-report measures of procrastination, depression, anxiety, and quality of life were distributed at pre-treatment assessment, post-treatment assessment, and one-year follow-up. Mixed effects models were used to investigate the long-term gains, and multiple linear regression for predictors of a positive treatment outcome, using the change score on the Irrational Procrastination Scale as the dependent variable. Intention-to-treat was implemented for all statistical analyses. Large within-group effect sizes for guided and unguided ICBT, Cohen’s d = .97–1.64, were found for self-report measures of procrastination, together with d = .56–.66 for depression and anxiety. Gains were maintained, and, in some cases, improved at follow-up. Guided and unguided ICBT did not differ from each other, mean differences ?.31–1.17, 95% CIs [?2.59–3.22], and none of the predictors were associated with a better result, bs ?1.45–1.61, 95% CIs [?3.14–4.26]. In sum, ICBT could be useful and beneficial in relation to managing procrastination, yielding great benefits up to one year after the treatment period has ended, with comparable results between guided and unguided ICBT.  相似文献

Decades of research and more than 20 randomized controlled trials show that Virtual Reality exposure therapy (VRET) is effective in reducing fear and anxiety. Unfortunately, few providers or patients have had access to the costly and technical equipment previously required. Recent technological advances in the form of consumer Virtual Reality (VR) systems (e.g. Oculus Rift and Samsung Gear), however, now make widespread use of VRET in clinical settings and as self-help applications possible. In this literature review, we detail the current state of VR technology and discuss important therapeutic considerations in designing self-help and clinician-led VRETs, such as platform choice, exposure progression design, inhibitory learning strategies, stimuli tailoring, gamification, virtual social learning and more. We illustrate how these therapeutic components can be incorporated and utilized in VRET applications, taking full advantage of the unique capabilities of virtual environments, and showcase some of these features by describing the development of a consumer-ready, gamified self-help VRET application for low-cost commercially available VR hardware. We also raise and discuss challenges in the planning, development, evaluation, and dissemination of VRET applications, including the need for more high-quality research. We conclude by discussing how new technology (e.g. eye-tracking) can be incorporated into future VRETs and how widespread use of VRET self-help applications will enable collection of naturalistic “Big Data” that promises to inform learning theory and behavioral therapy in general.  相似文献

The so-called Preface Paradox seems to show that one can rationally believe two logically incompatible propositions. We address this puzzle, relying on the notions of truthlikeness and approximate truth as studied within the post-Popperian research programme on verisimilitude. In particular, we show that adequately combining probability, approximate truth, and truthlikeness leads to an explanation of how rational belief is possible in the face of the Preface Paradox. We argue that our account is superior to other solutions of the paradox, including a recent one advanced by Hannes Leitgeb (Analysis 74.1).  相似文献

Logic programs under answer set semantics have become popular as a knowledge representation formalism in Artificial Intelligence. In this paper we investigate the possibility of using answer sets for qualitative decision making. Our approach is based on an extension of the formalism, called logic programs with ordered disjunction (LPODs). These programs contain a new connective called ordered disjunction. The new connective allows us to represent alternative, ranked options for problem solutions in the heads of rules: A × B intuitively means: if possible A, but if A is not possible then at least B. The semantics of logic programs with ordered disjunction is based on a preference relation on answer sets. We show that LPODs can serve as a basis for qualitative decision making.  相似文献

Objective: To understand the cultural context of illness in a homogeneous ethnic community, the Circassians. This is the first study of health perceptions and beliefs among Circassians. The Circassians arrived in Palestine from the Caucasus Mountain region more than a century ago. They constitute an endogamous group, whose members live in relative cultural isolation in two small villages in northern Israel, preserving their language and traditions. Design: Twenty-one elderly community members (men and women) were interviewed using open-ended interviews. Results: It was found that kutze (internal bodily resilience) is the central health-related concept and as such constitutes the main building block of a healthy and resilient community. Conclusions: By focusing on this specific community, the relationships between health beliefs and social organization were explored. Our findings highlight the need for the development of treatment approaches and/or health education that are deeply embedded in the cultural context, with special emphasis on the group's value infrastructure, life habits and health-related beliefs when studying various ethnic populations.  相似文献

Career exploration by Antioch College students who graduated between 1946 and 1955 (N=73) was studied to determine relationships between the occupational categories of cooperative education jobs taken in college (obtained from a campus archive) and subsequent work histories (obtained from surveying the graduates at about 70 years). Five hypotheses were tested. Results supported four of the hypotheses, with partial support for the fifth. Co-op jobs taken by the sample represented each of 23 occupational classifications, and most graduates took post-graduate jobs in occupational functions and contexts they had explored as co-op students. High levels of individuality in use of the co-op program and in career paths were found. Four co-op-to-career patterns were described, based on the degree to which functions and contexts were explored during college and career; a case study was included to exemplify each pattern. Gender differences were revealed in the patterns, but not the group data. Job context was particularly important in defining these patterns. Implications for research and practice were discussed tentatively, however given the lack of a control group, characteristics of the study sample, and particularities of the historical era studied, the ability to generalize beyond the study sample is limited.  相似文献
