Information security can be of high moral value. It can equally be used for immoral purposes and have undesirable consequences. In this paper we suggest that critical theory can facilitate a better understanding of possible ethical issues and can provide support when finding ways of addressing them. The paper argues that critical theory has intrinsic links to ethics and that it is possible to identify concepts frequently used in critical theory to pinpoint ethical concerns. Using the example of UK electronic medical records the paper demonstrates that a critical lens can highlight issues that traditional ethical theories tend to overlook. These are often linked to collective issues such as social and organisational structures, which philosophical ethics with its typical focus on the individual does not tend to emphasise. The paper suggests that this insight can help in developing ways of researching and innovating responsibly in the area of information security.  相似文献

Applying the framework of ecological rationality, the authors studied the adaptivity of group decision making. In detail, they investigated whether groups apply decision strategies conditional on their composition in terms of task‐relevant features. The authors focused on the recognition heuristic, so the task‐relevant features were the validity of the group members' recognition and knowledge, which influenced the potential performance of group strategies. Forty‐three three‐member groups performed an inference task in which they had to infer which of two German companies had the higher market capitalization. Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance. Time constraints had no effect on strategy use but did have an effect on the proportions of different types of arguments. Possible mechanisms underlying the adaptive use of recognition in group decision making are discussed.  相似文献

Background

Negative comments (teasing) on weight and body image in adolescence might predict body dissatisfaction, overweight and eating disorders in adulthood. This study investigated 134 nursing students for a relationship between a history of teasing, body image and weight.

Materials and methods

Subjects with a body mass index (BMI)>?25 kg/m2 reported more teasing compared with normal subjects whereas those with a BMI<?20 kg/m2 showed lower values compared with normal or overweight subjects. Teasing questionnaire values correlated with aspects of negative body image. The BMI was predicted by factors age (p?=?0.001), sex (p?=?0.016) and teasing subscale weight (p?=?0.001).

Conclusions

It is remarkable that low teasing experience was associated with low weight, which might point to underweight as protective factor against teasing; however, the cross-sectional design of this study precludes direct causal inferences.  相似文献

ABSTRACT

Frequent experiences of flow – an enjoyable state of optimal challenge – at work are associated with many positive individual and organizational outcomes. In our research, we examine how leaders affect subordinates’ flow experiences through subordinates’ work-related self-concept. Specifically, on the basis of self-concept theory, we propose that transformational leaders affect followers’ work-related self-concept, which we construe as followers’ psychological empowerment, consisting of the four sub-facets of meaning, competence, self-determination and impact. We further propose that psychological empowerment is positively related to flow experiences at work. In sum, we thus hypothesize that the effect of transformational leadership on employees’ flow experiences is mediated by psychological empowerment. Additionally, we propose that this indirect effect is moderated such that it is stronger for employees holding a formal leadership position. We tested the model with two two-wave questionnaire studies with employees (Study 1: N = 307 at time 1; N = 60 at time 2; Study 2: N = 611 at time 1; N = 271 at time 2) from different organizations. Path models reveal support for the mediation hypotheses in both samples but not for the moderated mediation hypothesis.  相似文献
