How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that (...) a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold‐based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non‐decreasing thresholds. Decreasing threshold strategies that “front‐load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.

Lawrence Sklar in his book, Physics and Chance (1993), proposes a sophisticated account of reduction of thermodynamics (TD) by statistical mechanics (SM). I argue that Sklar's analysis of the alleged reduction of TD by SM is problematic in several respects. I consider a few counterexamples to show that none of what Sklar takes to be the central features of successful reduction in science (unification and identification) holds in the case of TD and SM. I suggest the broader conclusion that a (...) more useful way of understanding the relationship between TD and SM is as collaboration and competition among alternative methodologies rather than reduction of one theory to another.

Over-general autobiographical memory retrieval is characterized by retrieval of categoric autobiographical memories. According to the CarFAX model, this tendency may result from avoidance which functions to protect the person against recalling details of upsetting memories. This study tested whether avoidance strategies impact on the ability to retrieve specific autobiographical memories. Healthy participants watched a negative video clip and were instructed to either suppress any thought , suppress any feeling , or think and feel naturally in response to the video. Participants (...) then completed the Autobiographical Memory Test. Participants engaging in either thought suppression or emotional inhibition retrieved fewer categoric autobiographical memories than controls. These findings challenge the affect regulation component of the CarFAX model insofar as they suggest that regulatory strategies that aim to reduce awareness of adverse emotional memories do not necessarily lead to increased recall of categoric autobiographical memories.

The Plight of Humanity in Paul In Paul and Palestinian Judaism, E. P. Sanders argues that, for Paul, humanity’s plight was not the condition that necessitated the solution of Jesus Christ. Instead, the solution was presented to Paul first on the Damascus road, and humanity’s plight was simply the logical corollary to the solution. This study will critically examine the particulars of Sanders’s argument— particularly with regard to Romans 7, Philippians 3, and Galatians 3—and offer some alternative exegetical analyses. This (...) essay will argue that, while the development of Paul’s thinking may indeed have run from solution to plight, the exposition of Paul’s thinking goes from plight to solution. The movement of Paul’s exposition may suggest that his conception of the plight of humanity was born out of his ideational milieu, which must have been fed, at least, by the Old Testament and evidenced, at least, by literature such as 4 Ezra.

Organizational leaders are eager to unlock the creative potential of followers. Yet, there is growing evidence that creativity can also have a dark side within organizations. Building on research linking creativity and unethical behavior, we develop the construct of creative unethicality—behavior that is both unethical and novel. We draw on social exchange theory to develop a model that identifies both why and when creative unethicality emerges within organizations. Specifically, we investigate the exchange dynamics through which creative support provided by empowering (...) leaders facilitates creative unethicality under conditions of high performance pressure. Across two multi-wave, multi-source field studies with employee-coworker and leader-subordinate dyads and an experimental study with a novel unethicality measure in a business simulation, we find convergent support for our theoretical model. These findings have important theoretical and practical implications for fostering creativity in organizations without simultaneously facilitating creative unethicality. (shrink)

BackgroundCOVID-19 break out has created panic and fear in society. A strict kind of lockdown was imposed in Wuhan, Hubei province of China. During home confinement due to lockdown, people face multidimensional issues. The present study explored the psychological impacts of COVID-19 home confinement during the lockdown period and Wuhan’s residents’ attitude toward physical activity.MethodsA cross-sectional online survey was conducted to collect the primary data according to the study objectives. The population was Wuhan residents who were in home confinement. A (...) total of 2280 participant’s reply to the online questionnaire survey and collected data after quantifying the data, about 2200 ; about female, about male, others about, and about were not disclosed their gender participants responses were used for analysis. The collected data were analyzed through appropriate statistical techniques.ResultsAccording to results, H1 is supported with β = −40.793, t = 57.835, p = 0.000, which claimed a negative association between COVID-19 lockdown policy and behavior and attitude. Results for H2 reveals that the COVID-19 lockdown policy have negative influence on emotional control with β = −0.769, t = 46.766, p = 0.000 and it is supported. H3 documented a significant positive relationship between COVID-19 lockdown policy and lockdown period psychological impact, which means lockdown policy, is the main reason to increase the lockdown psychological impact. Further, COVID-19 lockdown policy have negative influence on physical activity and self-belief with β = −0.657, t = 32.766, p = 0.000 and β = −0.620, t = −6.766, p = 0.000 respectively. H6 stated that there is a positive impact of behavior and attitude toward physical activity. The results for H6, behavior, and attitude affecting the physical activity with β = 0.401, t = 10, p = 0.000, which is supported.ConclusionCOVID-19 home confinement created various psychological impacts, negatively affecting the emotional state due to depression and anxiety. Physical activity is the best strategy to manage human nature’s psychological issues, and people’s attitudes were positive toward physical activity during home confinement. However, the lockdown policy also affects physical activity participation negatively, and a sedentary lifestyle prevailed during home confinement. (shrink)

As far as I’m concerned, Korean moral education is facing the new challenge and new era. I’m teaching Korean secondary school studens as an Ethic teacher in high school and EBS lecturer as well. I’m worried about Korean education especially in middle and high school. There was missing thinking those parts cause an entrance examination, only for university in Korea. In this a serious worry, I found some exits from significant experience. First, I’d like to mention about P4C (Philosophy for (...) children) Program which was learned from Professor Mattew Lipman of Mont Clair State University in New Jersey, U.S.A. This program is emphasizing upon thinking skill including creative, critical, and caring thinking. The huge shift from knowledge based education to thinking based education inKorea contemporarily. Also Student-based education is new stream of Korean education system. Teachers think students come to school to get knowledge, parents think children can learn judgment at school which was "lost area.”All this things come from philosophy, when we ask for reason it is a philosophical question. For example, "Why is he a hero?”, “He is brave.” "Why is he brave?" Which is philosophical conceptualization? Every day life gives us some questions and concepts like: love, freedom and philosophy gives us answers to those question so without philosophy we cannot have happy life. In reality of Korean education system there is no independent class for philosophy. So philosophy can be taught in Korean language classes or social studies. I started using P4C program from Lipman: I taught students making questions or making stories. These exercising result was remarkable and amazing. So questions are thebeginning of discovering new knowledge. Even if the knowledge is known by other people students can enjoy the process of discovering new knowledge. They could also get thinking skills. (shrink)

The paper studies the nature of understanding in condensed matter physics (CMP), mediated by the successful employment of its models. I first consider two obvious candidates for the criteria of model-based understanding, Van Fraassen's sense of empirical adequacy and Hacking's instrumental utility , and conclude that both are unsatisfactory. Inspired by Hasok Chang's recent proposal to reformulate realism as the pursuit of ontological plausibility in our system of knowledge, we may require the model under consideration to be understood (or intelligible) (...) before claiming model-based understanding. Here the understanding of a model typically consists of the following: figuring out at least one plausible (preferably realistic) physical mechanism for the model, determining the theoretical consequences of the model by mathematically probing it and developing our physical intuitions about the model. I consider the q-state Potts model to illustrate. After having understood a model, we may employ the model to understand its target phenomena in the world. This is done by matching one of the interpretative models of the model with the central features of the phenomena. The matching should be motivated (ideally both theoretically and empirically) in the sense that we have good reason to believe that the central features of the phenomena can be thought of as having more or less the same structure as postulated by the interpretative model. In conclusion, I propose a two-stage account of model-based understanding in CMP: (1) understanding of a model and (2) matching a target phenomenon with a well-motivated interpretative model of the model. Empirical success and instrumental utility both play their roles in the evaluation of how successful the model is, but are not the essential part of model-based understanding. (shrink)

Although sufficient attention has been paid to residents' attitudes to tourism in previous studies, few studies have used residents' attitudes to tourists and tourism simultaneously to explain their support for tourism. This study fills this gap by examining the effect of place image and host–tourist interactions on residents' attitudes to tourists and tourism, respectively, and their consequent reactions by considering the moderating effect of Chinese traditionality. The proposed model is tested using data from 357 residents living in Huangshan, a fifth-tier (...) city in China. Results demonstrate that attitudes to tourism and host-tourists interaction positively affect their pro-tourism behaviours. Moreover, attitudes to tourism mediate place the image's, host–tourists interaction's and attitudes to tourists' respective relationships with pro-tourism behaviours. Furthermore, the higher the Chinese traditionality of residents, the stronger the influence of their attitudes to tourism on pro-tourism behaviours. However, the relationship of place image and attitudes of residents towards tourists with pro-tourism behaviours are not supported. Findings offer critical implications for planners, practitioners and interested researchers. (shrink)

The sudden outbreak of coronavirus disease 2019 has caused a huge impact on the Chinese residents' health and economic level. In the pandemic background, the country and its institutions have introduced pandemic-related insurance to stabilize the national situation. At this stage, insurance has played an increasingly important role in social life. With the popularization of insurance, the idea of buying insurance to avoid risk has gradually become popular among people. Among them, the New Rural Cooperative Medical System has been farmers' (...) common choice. The NRCMS, a mutual aid system created by farmers spontaneously in the country, plays a great role in guaranteeing farmers access to basic health services, alleviating poverty caused by disease and returning to poverty due to disease, and promoting poverty alleviation and rural revitalization. Given this backdrop, we study the efficiency of the NRCMS that can effectively promote poverty alleviation and rural revitalization and ensure the people's happy life. Implementing the Data Envelopment Analysis, we find that technological progress is one of the main factors influencing the efficiency of the NRCMS. Therefore, it is important to improve the technology for providing the efficiency of the NRCMS and promoting the happiness of the society. (shrink)

Judges and jurors must make decisions in an environment of ignoranceand uncertainty for example by hearing statements of possibly unreliable ordishonest witnesses, assessing possibly doubtful or irrelevantevidence, and enduring attempts by the opponents to manipulate thejudge''s and the jurors'' perceptions and feelings. Three importantaspects of decision making in this environment are the quantificationof sufficient proof, the weighing of pieces of evidence, and therelevancy of evidence. This paper proposes a mathematical frameworkfor dealing with the two first aspects, namely the quantification ofproof (...) and weighing of evidence. Our approach is based on subjectivelogic, which is an extension of standard logic and probability theory,in which the notion of probability is extended by including degrees ofuncertainty. Subjective Logic is a framework for modelling humanreasoning and we show how it can be applied to legalreasoning. (shrink)

Evaluating readiness for discharge from the intensive care unit (ICU) is a critical aspect of patient care. Whereas evidence-based criteria for ICU admission have been established, practical criteria for discharge from the ICU are lacking. Often discharge guidelines simply state that a patient no longer meets ICU admission criteria. Such discharge criteria can be interpreted differently by different healthcare providers, leaving a clinical void where misunderstandings of patients’ readiness can conflict with perceptions of what readiness means for patients, families, and (...) healthcare providers. In considering ICU discharge readiness, the use and application of ethical principles may be helpful in mitigating such conflicts and achieving desired patient outcomes. Ethical principles propose different ways of understanding what readiness might mean and how clinicians might weigh these principles in their decision-making process. This article examines the concept of discharge readiness through the lens of the most widely cited ethical principles (autonomy [respect for persons], nonmaleficence/beneficence, and justice) and provides a discussion of their application in the critical care environment. Ongoing bioethics discourse and empirical research are needed to identify factors that help determine discharge readiness within critical care environments that will ultimately promote safe and effective ICU discharges for patients and their families.

Service providers working for a service organization are asked to express such positive emotions as joy, pleasure, and politeness required at the organizational level rather than their natural emotions they are experiencing at the moment. They cannot express their emotion they are actually going through and accordingly, their level of emotional labor and emotional dissonance influence on their job commitment and trust toward their organization. This study thus set out to investigate the effects of leading variables of emotional labor on (...) the level of emotional labor and the impact of emotional labor on organizational trust and organizational commitment with a subject group of college administrative staffs. Three underlying factors such as job stress, intimacy, and professionalism were identified as the determinants of emotional labor. Conceptual background about job stress, intimacy, emotional labor, and organizational effectiveness as the core variables of the study was investigated. Based on the conceptual background and our research questions, 5 research hypotheses and the proposed research model regarding the effects of emotional labor on organizational commitment and trust were developed. We also tried to include the moderating effects of work environment and gender of service providers on the research model. Unlike many different studies on emotional labor from the traditional perspective of service, this study also offers a practical implication by expanding and applying it to the field of college administrative service, which is an area where service providers are in the different working environment from the traditional company work environment. Finally, the managerial implications and the limitations of the study were also discussed. (shrink)
