一种改进的分层并行演化算法(英文)

提出了一种改进的分层并行演化算法。针对传统算法中"同构子种群"和"同步通信"所引发的问题,新算法构建了异构模型,并将各子种群充分连接。子种群一旦满足迁移条件,便可按照预设的迁移模式实施异步迁移。仿真实验结果表明,本文提出的新算法有效地解决了"征服问题"和"无效问题",避免了算法的过早收敛,提高了算法的效率。     

叙事哀伤照护赋能围产期临床人文关爱实践

安宁疗护和哀伤辅导是叙事医学的重要维度。以中国叙事医学理念为框架,围绕一则死胎家庭的围产期叙事照护及叙事哀伤辅导案例,阐述围产期丧失造成的哀伤剥夺如何导致失胎/失婴家庭成员陷入严重的创伤叙事闭锁和心身失调状态,进而阐明如何通过强化多学科团队的协同作用,通过产科医护人员的叙事照护,引领丧子家庭走出至暗时刻,重新回归正常的生命叙事进程。叙事性的哀伤支持是最佳的哀伤支持方式,唯有重视围产期叙事生态,积极开展有效的叙事照护,增强生育体验与生育信心,才能对抗生育率下降的社会危机。

     

Why schema-violations are sometimes preferable to schema-consistencies: The role of interest and openness to experience

We investigated the appraisal processes and personality antecedents that regulate people’s attraction to schema-violations - targets and objects that disconfirm schema- and stereotype-based expectancies. In two studies a preference for schema-violations (vs. consistencies) correlated positively with openness to experience, and negatively with the need for structure. In the second study, schema-violations were seen as more surprising (by all individuals), decreasing intentions to approach schema-violations, but were also seen as more interesting (by those higher in openness to experience), increasing intentions to approach and accept schema-violations. This suggests that two opposing processes - appraisals of surprise and appraisals of interest - regulate reactions to schema-violations, and that these processes are bounded by individual differences in openness to experience.     

Social power tactics and subordinates’ compliance at work: The role of need for cognitive closure

IntroductionThe present research highlights the importance of subordinates’ motivation for compliance-related phenomena.ObjectivesThe aim of this research was to examine subordinates’ willingness to comply with their supervisors’ harsh and soft power tactics as a function of subordinates’ need for cognitive closure.MethodTwo cross-sectional studies were conducted in five different Italian organizations, namely, a bank, a federation of small businesses, a security company, an oil company, and a hospital.ResultsIt was found that subordinates high (vs. low) on need for closure reported greater willingness to comply with harsh social power tactics, but lower willingness to comply with soft power tactics.ConclusionOur findings nuance prior research by showing that soft (vs. harsh) power tactics are not always the most effective power tactics in organizational setting (e.g., Pierro et al., 2004; Raven et al., 1998).     

Working Hard to Take the Easy Way Out: How the Need for Cognitive Closure Shapes Strategic Effort Investment to Ease Future Decision Making

Consumers make countless decisions each day that force them to determine the amount of effort they are willing to invest into the decision process. Due to their desire for immediate resolution and propensity to seize upon available options, individuals high in the need for cognitive closure make decisions that are traditionally associated with reduced effort investment. Counter to this traditional perspective, this research demonstrates that those seeking closure strategically invest effort into the decision process, so long as the initial effort investment is expected to simplify similar decisions in the future. Three experiments demonstrate that those motivated by closure put forth greater effort when they expect to repeat the decision (Experiment 1) and in contexts where a justifiable choice option is not readily available (Experiment 2). Furthermore, this effort investment is shown to payoff in terms of streamlining subsequent decision making (Experiment 3). These findings detail the strategic use of effort by those seeking closure to ease future decision making and thus provide a conceptual framework for when and why those seeking closure allocate effort in decision making.     

Victims' Stories of Human Rights Abuse: The Ethics of Ownership,Dissemination, and Reception

This paper addresses three commentaries on Victims' Stories and the Advancement of Human Rights. In response to Vittorio Bufacchi, it argues that asking victims to tell their stories needn't be coercive or unjust and that victims are entitled to decide whether and under what conditions to tell their stories. In response to Serene Khader, it argues that empathy with victims' stories can contribute to building a culture of human rights provided that measures are taken to overcome the implicit biases and colonialist interpellations she identifies. In response to Andrea Westlund, it proposes a taxonomy of types of narrative closure and offers some arguments to strengthen her view that empathy with victims' stories endows audience members with a new reason and new motivation to support human rights.     

Measurement and Indeterminacy in the Quantum Mechanics of Dirac

The quantum-measurement problem and the Heisenberg indeterminacy principle are presented in the language of the Dirac formulation of the quantum theory. Particularly the relationship between quantum state prior to measurement and the result of the measurement are discussed. The relation between the indeterminacy principle and the analog between quantum and classical systems is presented, showing that this principle may be discussed independently of the wave-particle duality. The importance of statistics in the treatment of many body systems is outlined and the approach to investigating God's interaction with human beings is discussed in this context. The treatment is nonmathematical.     

Motivated Closed‐Mindedness Mediates the Effect of Threat on Political Conservatism

In this article we synthesize theory and research from several areas of psychology and political science to propose and test a causal model of the effects of threat on political attitudes. Based in part on prior research showing that fear, threat, and anxiety decrease cognitive capacity and motivation, we hypothesize that under high (vs. low) threat, people will seek to curtail open‐ended information searches and exhibit motivated closed‐mindedness (one aspect of the need for cognitive closure). The subjective desire for certainty, control, and closure, in turn, is expected to increase the individual's affinity for political conservatism, insofar as resistance to change and adherence to authority figures and conventional forms of morality are assumed to satisfy these epistemic motives more successfully than their ideological opposites. Consistent with this account, we find in Studies 1a and 1b that putting people into a highly threatened mindset leads them to exhibit an increase in motivated closed‐mindedness and to perceive the world as more dangerous. Furthermore, in Study 2 we demonstrate that a subtle threat manipulation increases self‐reported conservatism (or decreases self‐reported liberalism), and this effect is mediated by closed‐mindedness. In Study 3, we manipulated closed‐mindedness directly and found that high (vs. low) cognitive load results in a greater affinity for the Republican (vs. Democratic) party. Finally, in Study 4 we conducted an experiment involving political elites in Iceland and found that three different types of threat (to the self, group, and system) all led center‐right politicians to score higher on closed‐mindedness and issue‐based political conservatism. Implications for society and for the theory of ideology as motivated social cognition are discussed.     

Emerging Technologies and the Future of Philosophy

This article examines how a class of emerging technologies—specifically, radical cognitive enhancements and artificial intelligence—has the potential to influence the future of philosophy. The article argues that progress in philosophy has been impeded, in part, by two specific constraints imposed on us by the natural architecture of our cognitive systems. Both of these constraints, though, could in principle be overcome by certain cognitive technologies currently being researched and/or developed. It surveys a number of these technologies, and then looks at a particular metaphilosophical stance (called “inflationism”) that advocates amplifying the abilities of philosophers rather than reducing the ambitions of philosophy, given the apparent “teleological gap” between philosophy's ultimate goal (i.e., “the truth”) and the limited capacities of our evolved mental machinery.
