Achievements are among the things that make a life good. Assessing the plausibility of this intuitive claim requires an account of the nature of achievements. One necessary condition for achievement appears to be that the achieving agent acted competently, i.e. was not just lucky. I begin by critically assessing existing accounts of anti-luck conditions for achievements in both the ethics and epistemology literature. My own proposal is that a goal is reached competently (and thus an achievement), only if the actions of the would-be-achiever make success likely, and that this is the reason why she acts that way.  相似文献

Common resource dilemmas involve collectively coordinating individual choices to promote group efficiency. Equal division represents one of the most important coordination rules. Previous research suggests that individuals follow the equality rule for different reasons. Some individuals behave cooperatively out of their concern for other's welfare, whereas some individuals cooperate strategically to enhance personal gains. Building on the dual‐process perspective, the authors aim to differentiate strategic fairness from true fairness in solving a resource dilemma. In four experiments, the effect of cognitive processing manipulations on individual harvesting behavior in a one‐shot resource dilemma was tested against participants with different social values. Results consistently showed that prosocials, who value joint outcome and equality, requested significantly less money than did proselfs, who value personal gain. More importantly, prosocials in the intuition and deliberation conditions request similar amounts, whereas proselfs in the intuition condition request more money than those in the deliberation condition. The results were further validated by a follow‐up meta‐analysis based on the four experiments. The implications of the dual‐process perspective for social coordination research are discussed.  相似文献

The StemBANCC consortium was a large European consortium bringing together scientists from academic institutions and the pharmaceutical industry. The aim of the consortium was to produce 1500 induced pluripotent stem cell (iPSC) lines from participants with a variety of common, complex diseases. These cell lines were intended to help develop iPSC as tools for screening small molecule drug candidates and modelling human diseases in vitro. The scale of investment in this and other biobanks presents iPSC as a valuable commodity. However, StemBANCC was also mandated to make its making cells and data available to European researchers on a not-for-profit basis. To understand how making this quantity of stem cells and data available is configured as a valuable and worthwhile investment for the consortium partners, research materials (project documents, scientific literature and interviews with scientists working on StemBANCC) were analysed using theoretical tools from Valuation Studies. Combining STS and economic sociology, valuation studies analyse how the worth of things, ideas and phenomena result from context-specific practices of assessment and evaluation; worth incorporates moral, financial, scientific, economic. social and cultural registers of value. In this sense, practitioners evaluate the worth of the StemBANCC cells and data at a variety of sites, from participant recruitment to online databases. This provides an alternative to biovalue and similar conceptual models for theorising the generation of value in the Life Sciences.  相似文献

Using Quality Management System (QMS) enables the organization to fulfil its purpose and mission to meet customers and regulatory requirements and improve its effectiveness and efficiency on a continuous basis, Quality Audit is very critical tool to ensure that the standards, policies and/or procedures are applied in the organization as planned in QMS, in real world applications, the results of the Quality Audit process depend on the auditors’ human judgments that characterized with doubts sometimes, estimating values another times, and using general impressions in his judgment, which motivate to introduce for the first time the Neutrosophic Quality Audit (NQA) model which can be extended to manage and audit in the future. NQA will be used to enhance the way of evaluating the quality audit results while many uncertainty aspects and indeterminacy do exist, the proposed model using Single Value Neutrosophic Numbers (SVNN) which is an instance of neutrosophic set, to overcome the weakness of using a crisp value to present the result of the audit findings, in addition, using Simplified Neutrosophic Weighted Geometric Average Operator (SNWGAO), and cosine similarity degree, an illustrative example is provided to validate the proposed model.  相似文献

本研究采用汉化的Schwartz《肖像价值观问卷》(2012)测量了2569人的大样本,以验证Schwartz新价值观理论及其工具在中国的适用性及中国人价值观结构特点。结果表明,19种价值观内部一致性系数平均为0.66,范围从“支配权力”价值观的0.54到“社会安全”价值观的0.80,验证性因素分析各项指标均达到可接受水平;中国人个人定向类价值观之间的相关关系与原理论假设不相符合;个人定向类和社会定向类价值观之间,出现了多项位置相对、在原理论中假定为低相关的价值观呈高相关关系。表明Schwartz等(2012)价值观理论虽从测量学角度适用中国人群,但其不能预测和解释中国人价值观的“个人”与“社会”辩证统一与交叉融合特点。  相似文献

Value transmission from one generation to the next is a key issue in every society, but it is not clear which parents are the most successful in transmitting their values to their children. We propose parents’ prosocial educational goals as key predictors of parent–child value similarity. Accordingly, we hypothesized that the more parents wanted their children to endorse values of self‐transcendence (helping, supporting, and caring for others) and the less parents wanted their children to endorse the opposing values of self‐enhancement (striving for power and achievement), the higher would be parent–child overall value similarity. Findings from two studies of families – Study 1: 261 Swiss families, children aged 7–9 years; Study 2: 157 German families, children aged 6–11 years – confirmed this hypothesis. The effect was even stronger after controlling for values that prevail in the Swiss and German society, respectively. We integrate evidence from this study of values in families with young children with existing findings from studies with adolescent and adult children, and we discuss potential pathways from parents’ educational goals to parent–child value similarity.  相似文献

The present study investigates the connection between personal value preferences, group identifications, and cultural practices among Palestinian Israelis working in close contact with the Jewish population in Israel. One hundred twenty-two Palestinian Israelis participated in the study. The participants were employed in different professional positions in the Tel Aviv Metropolitan area and were recruited to the study using the snowball technique. A stronger national identification was associated with a higher preference for the security and conformity values, and a lower preference for the humility values. A stronger ethnic identification was associated with a lower preference for the security, power, and stimulation values. Group identifications mediated the connection between personal value preferences and cultural practices. A longer time working in close contact with the majority group and less frequent visits home were associated with a greater adherence to the majority group’s cultural practices but not with adherence to the ethnic group’s practices and not with the group identifications.  相似文献

This study examines the relationship between job insecurity and discretionary behaviors, that is, organizational citizenship behaviors (OCB) and counterproductive work behaviors (CWB), with the purpose to extend knowledge on the theoretical explanations for these outcomes. Considering the employment relationship with the organization, two different perspectives are suggested and compared in a multiple mediator model, in order to understand the reasons for discretionary behaviors. We draw upon social exchange theory as the basis of psychological contract perceptions and we rely on the group value model to explain organizational justice evaluations. A total of 570 blue‐collar workers in Italy participated in our survey. The results show that job insecurity is indirectly related to OCB and CWB through psychological contract breach and organizational injustice. Both mediational mechanisms have equivalent strength in explaining the relationships, namely, they are complementary processes in accounting for both behaviors. These findings suggest that employees’ behaviors in job insecure contexts are driven not only by concerns related to the exchange of resources with the organization, but also by evaluations about their value as important members of the group.  相似文献

Measurement instruments assessing multiple emotions during epistemic activities are largely lacking. We describe the construction and validation of the Epistemically-Related Emotion Scales, which measure surprise, curiosity, enjoyment, confusion, anxiety, frustration, and boredom occurring during epistemic cognitive activities. The instrument was tested in a multinational study of emotions during learning from conflicting texts (N?=?438 university students from the United States, Canada, and Germany). The findings document the reliability, internal validity, and external validity of the instrument. A seven-factor model best fit the data, suggesting that epistemically-related emotions should be conceptualised in terms of discrete emotion categories, and the scales showed metric invariance across the North American and German samples. Furthermore, emotion scores changed over time as a function of conflicting task information and related significantly to perceived task value and use of cognitive and metacognitive learning strategies.  相似文献
