Using data from a longitudinal study, the present study employed a latent class mover-stayer analytical strategy to examine both the cross-sectional and longitudinal (+33 months) relationship between membership of stress classes, and subjective life expectancy. Participants were from 21 High schools in Scotland and Northern Ireland. Data were collected in the first year of High school (mean age = 12.5 years), and at +33 months (fourth year, or school year 11). Sample 1 consisted of 1171 adolescents (40.82% females, 2.56% unreported) in Northern Ireland. Sample 2 consisted of 1059 adolescents (52.79% females, 1.32% unreported) in Scotland. Adolescents with the lowest levels of stress projected the highest subjective life expectancy scores. Longitudinal analyses were jumbled and not in keeping with cross-sectional results. More research may be needed on the trajectory of subjective life expectancy over time before it can be depended upon as a reliable outcome variable in adolescent development.  相似文献

This study investigated how creative personality, psychological empowerment, and job stress affect creative self-efficacy and innovative behavior in hospitality employees. A hypothesized moderating role of knowledge-sharing role in the relationship between creative self-efficacy and innovative behavior was also tested. Three hundred and thirty-nine employees and 89 supervisors employed by International Tourist Hotels in Taiwan participated in the study. A structural equation modeling analysis indicated that creative self-efficacy significantly mediates the effects of creative personality and psychological empowerment on innovative behavior in the hospitality industry. The positive effect of creative self-efficacy on innovative behavior was larger in high knowledge-sharing work environments than in low knowledge-sharing work environments. Theoretical and practical implications are further discussed.  相似文献

Authenticity is generally indicated to be an important predictor to subjective well-being. However, remarkably few empirical researches investigated possible psychological mechanism underlying the process. The purpose of the current research is to explore whether mindfulness can explain one pathway between authenticity and subjective well-being. By conducting a cross-sectional study and a time-lagged study, we verified that higher authenticity associated higher subjective well-being via higher mindfulness. Furthermore, the effect of authenticity on subjective well-being was specifically through two facets of mindfulness–describing and acting-with-awareness. These results contribute to a better understanding of the association of authenticity and subjective well-being. Moreover, these findings suggest that mindfulness training may be a useful technique to accelerate the transformation from being thyself to being happy.  相似文献

The use of social networking websites (SNWs) during employee selection is gaining popularity in organizations. Using a foundation that integrates identity and situational strength theories, we develop a conceptual framework that differentiates SNW information from information gathered through traditional selection procedures, and distinguishes between SNW types. Research questions and hypotheses are tested using a survey of 291 hiring professionals. Results indicate that SNW content is considered useful and is regularly utilized during hiring. Some SNW content is viewed positively (e.g., information supporting qualifications), while other information leads to negative perceptions (e.g., discriminatory comments). Finally, results support a differentiation between personal and professional SNW, as the kind of information sought and the effectiveness of assessing various work‐related constructs differs between these SNW categories.  相似文献

A gist retrieval-orientation decreases one’s ability to remember objective details from past experiences. Here, we examined whether a gist retrieval-orientation manipulation can impact both the objective and subjective aspects of remembering. Young participants took part in two cued-recollection tasks in which they studied pictures associated with labels; at retrieval, from the labels, they evaluated the vividness of their memories of the corresponding pictures, and recalled picture details. Before retrieval, participants were submitted either to a gist or a control retrieval-orientation (one per task). Results revealed that the amount of recalled details was lower following the gist condition while vividness ratings did not differ between the two retrieval orientations. Critically, the amount of recalled details predicted the corresponding vividness ratings to a similar extent in the gist and control conditions, thus suggesting that recollected memory traces in the gist condition were still rich enough to be judged as subjectively vivid.  相似文献

IntroductionWriting and metacognition play an essential function in the learning process, in that writers engage arduous cognitive efforts by selecting and organizing ideas, then reviewing and readjusting them.ObjectiveThe present research aimed to construct and validate a self-report instrument to measure some specific metacognitive processes implicated in writing planning. Two categories of metacognitive components were considered: metacognitive knowledge and self-regulation strategies.MethodBased on exploratory and confirmatory analyses, the Metacognitive Components of Planning Writing Self-inventory (MCPW-I) was constructed and validated. This instrument is composed of three factors: Metacognitive Conditional Knowledge – MCK (6 items), Covert Self-regulation – CSF (4 items), and Environmental self-regulation – ESF (5 items). 1022 undergraduates students engaged in various programs of a French university filled in the inventory.ResultsThe alpha coefficients indicated a reliable internal consistency and the test-retest reliability showed a good temporal stability. Correlational analyses revealed that the CRS factor was related to ESR and MCK factors, and these last two were not correlated with each other. After the analysis of variance, the responses relative to ESR and MCK dimensions differed according to gender, but no differences relatively to the academic disciplines considered was found. Concerning the predictive validity, CSF and MCK were correlated with writing performance.ConclusionThe results confirm the validity and reliability of the MCPW-I which constitutes a new research tool for the study of metacognitive processes of writing.  相似文献

This study aims to comprehend traffic safety competencies in high school students from two specific regions of Peru, as well as to analyze the differences between both groups. For this purpose, a qualitative study was carried out which consisted of eight focus groups in high schools, three of them in the metropolitan area of Lima (Lima region) and five in the province of Rodríguez de Mendoza (the Amazonas region). The focus groups were constituted by 73 students enrolled in the last three years of high school, named 3rd, 4th and 5th grade of secondary education, whose ages ranged from 14 to 18 years. The collected data were analyzed employing elements of Grounded Theory and Axiomatic Set Theory. The main findings reveal that most participants have a general understanding of traffic rules and the proper use of the components of traffic safety. Thus, they understand the traffic rules as road signs that regulate the behavior of drivers and pedestrians. In addition, participants know the proper procedure to follow at traffic lights, pedestrian walkways and how to use seat belts. They also identify the driver’s tiredness/drowsiness, and the consumption of alcohol and drugs as potential factors that cause traffic accidents. No causes that are linked to pedestrian behavior were identified, and only participants from the Amazonas region mentioned speeding as a contributing factor. On the other hand, participants report that in practical situations they engage in risky behavior and fail to comply with transit rules. They justify this behavior by citing poor infrastructure, vehicle malfunctions, and the need get around quickly in order to get things done. Finally, the implications of the results are discussed and compared to the content and implementation of the Peruvian Road Safety Educational Program (PENSV, for its acronym in Spanish), providing recommendations that can aid evidence‐based policy making in Peru.  相似文献

For scientific knowledge to be trustworthy, it needs to be dissociated from material interests. Disinterested research also performs other important non-instrumental roles. In particular, academic science has traditionally provided society with reliable, imaginative public knowledge and independent, self-critical expertise. But this type of science is not compatible with the practice of instrumental research, which is typically proprietary, prosaic, pragmatic and partisan. With ever-increasing dependence on commercial or state funding, all modes of knowledge production are merging into a new, ‘post-academic’ research culture which is dominated by utilitarian goals. Growing concern about conflicts of interest is thus a symptom of deep-seated malaise in science and medicine. An expanded version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.  相似文献

Professional autonomy is often described as a claim of professionalsthat has to serve primarily their own interests. However, it can also beseen as an element of a professional ideal that can function as astandard for professional, i.e. medical practice. This normativeunderstanding of the medical profession and professional autonomy facesthree threats today. 1) Internal erosion of professional autonomy due toa lack of internal quality control by the medical profession; 2)the increasing upward pressure on health care expenses that calls for ahealth care policy that could imply limitations for the professionalautonomy of physicians; 3) a distorted understanding of theprofession as being based on a formal type of knowledge and relatedtechnology, in which other normative dimensions of medical practice areneglected and which frustrates meaningful communication betweenphysicians and patients. To answer these threats a normative structureanalysis of medical practice is presented, that indicates whichprinciples and norms are constitutive for medical practice. It isconcluded that professional autonomy, normatively understood, should bemaintained to avoid the lure of the technological imperative and toprotect patients against third parties' pressure to undertreatment.However, this professional autonomy can only be maintained if members ofthe profession subject their activities and decisions to a criticalevaluation by other members of the profession and by patients and ifthey continue to critically reflect on the values that regulate today'smedicine.  相似文献

Infants aged 3-5 months (mean of approximately 4 months) were given a novel anticipatory looking task to test object permanence understanding. They were trained to expect an experimenter to retrieve an object from behind a transparent screen upon hearing a cue ("Doors up, here comes the hand"). The experimenter then hid the object behind one of two opaque screens and after either 2 or 8s gave the "doors up" cue. Infants looked to the correct location after the two-second delay, but not after the eight-second delay. This indicates a brief memory that the object is present behind the occluder. The study provides converging evidence that infants grasp object permanence by a young age. The novel anticipatory looking paradigm helps rule out counter-explanations applied to violation-of-expectation tasks.  相似文献
