The objective of this article is to investigate ethical aspects of technology through the moral term “paternalism”. The field of investigation is medicine. The reason for this is twofold. Firstly, “paternalism” has gained moral relevance through modern medicine, where physicians have been accused of behaving paternalistic and threatening patients’ autonomy. Secondly, medicine is a brilliant area to scrutinise the evaluative aspects of technology. It is argued that paternalism is a morally relevant term for the ethics of technology, but that its traditional conception is not adequate to address the challenges of modern technology. A modification towards a “technological paternalism” is necessary. That is, “technological paternalism” is a fruitful term in the ethics of technology. Moreover, it is suited to point out the deficiencies of the traditional concept of paternalism and to reform and vitalise the conception of paternalism in ethics in order to handle the challenges of technology.  相似文献

The benefits of mindfulness-based interventions to alleviate anxiety and depression have been supported by many studies. Given the effectiveness of mindfulness-based interventions on anxiety and depression, the underlying mechanisms need to be explored. Using a randomized waitlist-controlled design, this study investigated whether anxiety sensitivity was a potential mechanism for the impact of mindfulness training on anxiety and depression. Participants with high psychological distress were randomly assigned to an eight-week mindfulness intervention (N = 35) or a wait-list control group (N = 34). Before and after the intervention or corresponding waitlist period, participants completed measures of anxiety and depression severity and impairment and anxiety sensitivity. Separate mixed ANOVA demonstrated significant group (intervention vs. control group) × time (pre- vs. post-test) interactions for anxiety sensitivity and overall anxiety severity and impairment and marginally significant interaction for overall depression severity and impairment. Moreover, simple mediation models showed that reductions of anxiety sensitivity from pre- to post-test mediated the impact of mindfulness training on changes in anxiety and depression severity and impairment. The findings suggest that anxiety sensitivity is a potential mechanism underlying the effect of mindfulness training on anxiety and depression, which provides a new perspective for the study of processes of change of mindfulness-based interventions.  相似文献

Paradoxical performance effects (‘choking under pressure’) are defined as the occurrence of inferior performance despite striving and incentives for superior performance. Experimental demonstrations of these effects on tasks analogous to athletic performance and the theories that may explain them are reviewed. At present, attentional theories seem to offer the most complete explanation of the processes underlying paradoxical performance effects. In particular, choking may result from distraction or from the interference of self-focused attention with the execution of automatic responses. Experimental findings of paradoxical performance decrements are associated with four pressure variables: audience presence, competition, performance-contingent rewards and punishments, and ego relevance of the task. The mediating factors of task complexity, expectancies, and individual differences are discussed.  相似文献

Alternative conceptions of the relationship between job perceptions and job satisfaction were tested using survey responses from 450 engineers. One model, based on Job Characteristics Theory (JCT) (e.g., Hackman & Lawler, 1971), predicted that job perceptions lead to job satisfaction (JP → Sat). A second model, based on Social Information Processing (SIP) theory (e.g., Salancik & Pfeffer, 1978) and Zajonc′s (1980) theory, predicted that job satisfaction leads to job perceptions (Sat → JP). A third model, which specified a reciprocal relationship between perceptions and satisfaction (JP ↔ Sat), was developed based on James′ theory (e.g., James, Hater, Gent, & Bruni, 1978). Supervisors′ ratings of departmental characteristics were used as contextual variables along with individual difference measures as antecedents of job perceptions and job satisfaction. Model contrasts performed using LISREL VII yielded clear support for the reciprocal model based on James′ theory, in contrast to the unidirectional models based on JCT and on SIP and Zajonc′s theory. The magnitudes of the two reciprocal paths linking job perceptions and job satisfaction did not differ significantly. Directions for future research and application were offered.  相似文献

For detecting differential item functioning (DIF) between two or more groups of test takers in the Rasch model, their item parameters need to be placed on the same scale. Typically this is done by means of choosing a set of so-called anchor items based on statistical tests or heuristics. Here the authors suggest an alternative strategy: By means of an inequality criterion from economics, the Gini Index, the item parameters are shifted to an optimal position where the item parameter estimates of the groups best overlap. Several toy examples, extensive simulation studies, and two empirical application examples are presented to illustrate the properties of the Gini Index as an anchor point selection criterion and compare its properties to those of the criterion used in the alignment approach of Asparouhov and Muthén. In particular, the authors show that—in addition to the globally optimal position for the anchor point—the criterion plot contains valuable additional information and may help discover unaccounted DIF-inducing multidimensionality. They further provide mathematical results that enable an efficient sparse grid optimization and make it feasible to extend the approach, for example, to multiple group scenarios.  相似文献

Previous studies have found that social anxiety and experiential avoidance (EA) are significantly associated, but the directionality of this relationship has not been firmly established. The present study examined momentary EA and social anxiety using repeated measurements during an opposite-sex interaction. Participants were 164 individuals (50% female): 42 were diagnosed with social anxiety disorder (SAD) and the remaining 122 were non-socially-anxious individuals (NSAs). Participants formed 42 experimental dyads including 1 individual with SAD and 1 NSA individual, and 40 control dyads including 2 NSA individuals. Lower-level mediational modeling indicated that for individuals with SAD, a reciprocal relationship was observed in which changes in both EA and social anxiety mediated changes in each other. However, changes in EA explained approximately 89% of changes in social anxiety whereas changes in social anxiety explained approximately 52% of changes in EA throughout the interaction. For NSA individuals, only social anxiety predicted EA. These findings point to a deleterious cycle driven mostly by EA among individuals with SAD, but not NSA individuals. Findings are discussed within the context of previous empirical findings as well as acceptance and commitment therapy (ACT) and cognitive-behavioral models of psychopathology.  相似文献

Well-functioning teamwork has frequently been linked to increased work satisfaction and performance. However, there is a paucity of research on the different types of roles in teams. Recently, a new model of role behavior in teams was proposed (comprising seven such team roles: Idea creator, information gatherer, decision-maker, implementer, influencer, energizer, and relationship manager), but an assessment instrument was lacking so far. The present study describes the construction of an instrument for the assessment of these roles in two samples (N = 291 and 274) and examines their relationships with character strengths and job satisfaction. Results show that the team roles are positively related to job satisfaction and most character strengths. The findings support the important role of character strengths in work-related settings and lay ground for further studies on team roles.  相似文献

What determines human ratings of association? We planned this paper as a test for association strength (AS) that is derived from the log likelihood that two words co‐occur significantly more often together in sentences than is expected from their single word frequencies. We also investigated the moderately correlated interactions of word frequency, emotional valence, arousal, and imageability of both words (r's ≤ .3). In three studies, linear mixed effects models revealed that AS and valence reproducibly account for variance in the human ratings. To understand further correlated predictors, we conducted a hierarchical cluster analysis and examined the predictors of four clusters in competitive analyses: Only AS and word2vec skip‐gram cosine distances reproducibly accounted for variance in all three studies. The other predictors of the first cluster (number of common associates, (positive) point‐wise mutual information, and word2vec CBOW cosine) did not reproducibly explain further variance. The same was true for the second cluster (word frequency and arousal); the third cluster (emotional valence and imageability); and the fourth cluster (consisting of joint frequency only). Finally, we discuss emotional valence as an important dimension of semantic space. Our results suggest that a simple definition of syntagmatic word contiguity (AS) and a paradigmatic measure of semantic similarity (skip‐gram cosine) provide the most general performance‐independent explanation of association ratings.  相似文献
