Abstract

Academic procrastination is a common phenomenon in students that can have a negative impact on effective learning, academic achievement, self-esteem, and quality of life. This study examined the associations among the two dimensions of perfectionism (personal standards perfectionism and evaluative concerns perfectionism), academic hardiness, and academic procrastination, as well as the moderating role of academic hardiness in the relationship between the two dimensions of perfectionism and academic procrastination. Participants of this study included 410 high school students in grades 9 to 12 from six schools in Tehran, Iran who completed the Almost Perfect Scale-Revised, the Academic Hardiness Scale, and the Procrastination Assessment Scale. The results indicated that personal standards perfectionism and academic hardiness had negative relationships with academic procrastination, whereas evaluative concerns perfectionism had a positive relationship with academic procrastination. Interaction-moderation analysis demonstrated that academic hardiness only played a buffering role in the relationship between evaluative concerns perfectionism and academic procrastination. The results of this study elucidate the experience of academic procrastination in students and highlight the role of academic hardiness and personal standards perfectionism. Implications for educators and psychologists are discussed.  相似文献

The question of whether “we drive as we live” or whether “we are transformed behind the wheel” generates discussion at all levels from the scholarly to the popular. To shed light on this issue, this study measured the personality traits of general anger and driving anger and four modes of expression common to both contexts (verbal, physical, displaced and adaptive) in a sample of 198 drivers. The results showed a moderate correlation between the two measured traits and indicated that each mode of expression correlated better with its equivalent mode in the other context than it did with the other modes of expression. Next, three hypotheses about the multivariate relationship were tested through five path models. These models confirmed that general anger and driving anger, although related to each other, are two different traits: a propensity to general anger and a propensity to driving anger. However, it was observed that when someone experiences anger, either on or off the road, it is expressed in the same way, given that each mode of expression behind the wheel is associated to both the propensity to driving anger and the equivalent mode of expression in a general context. Finally, the study’s implications are discussed.  相似文献

ABSTRACT

A complex set of European regulations aims to facilitate regenerative medicine, harmonizing good clinical and manufacturing standards and streamlining ethical approval procedures. The sociology of standardization has elaborated some of the effects of regulation but little is known about how such implementation works in practice across institutions and countries in regenerative medicine. The effects of transnational harmonization of clinical trial conduct are complex. A long-term ethnographic study alongside a multinational clinical trial finds a range of obstacles. Harmonization standardizes at one level, but implementing the standards brings to the fore new layers of difference between countries. Europe-wide harmonization of regulations currently disadvantages low-cost clinician-lead research in comparison to industry-sponsored clinical trials. Moreover, harmonized standards must be aligned with the cultural variations in everyday practice across European countries. Each clinical team must find its own way of bridging harmonized compulsory practice with how things are done where they are, respecting expectations from both patients and the local hospital ethics committee. Established ways of working must further be adapted to a range of institutional and cultural conventions that affect the clinical trial such as insurance practices and understandings of patient autonomy. An additional finding is that the specific practical roles of team members in the trial affect their evaluation of the importance of these challenges. Our findings lead to conclusions of wider significance for the sociology of standards concerning how regulation works and for medical sociology about how trial funding and research directions in stem cell medicine intersect.  相似文献

道德评价标准的理想性、前瞻性是道德存在的意义,是道德导向功能、教育功能、规范功能发挥作用的理论前提。从“道德容许行为”到“次道德”范畴的提出,道德评价标准的理想性、前瞻性正在丧失,道德的规范作用、引领作用日益淡化,道德已经跌出了“道德底线”。道德在沦为经济附庸的同时丧失自己的高贵品位。因此,道德建设必须高扬理想的旗帜,实现道德评价标准理想性和现实性的有机统一。  相似文献

In driver behaviour research there is considerable focus on distraction caused by specific external systems, such as navigation systems or mobile telephones. However, it is not clear whether self-paced actions such as daydreaming have the same negative effects on driving behaviour. In a driving simulator study, the effects of an internal cognitive process (internal distraction) on driving behaviour and physiological data were compared to the effects of a sound and speech task (external distraction). Three groups of participants made two drives on a motorway, with one control group, one internal distraction group and one external distraction group. Dependent measures included driving behavioural measures, physiological measures and a subjective indication of participants’ experienced involvement in the driving task.The effects of both the internal and external distraction task were reflected in speed, number of lane changes, deceleration, glances and subjective ratings. When an effect was found for both the internal and the external distraction task, the results indicated similar (negative) effects. Participants also indicated that they had the feeling they were less involved in the driving task with both secondary tasks.  相似文献
