We propose a person-centered framework for conceptualizing subjective careers in an increasingly boundaryless work context. Specifically, we argue that entrepreneurship, professionalism, and leadership (EPL) can serve as three key dimensions of subjective career space. We relate this framework to earlier macro-level national and organizational career models proposed by Kanter (1989) and Schein (1978). Our empirical study involving 10,326 Singaporean university students demonstrated that entrepreneurial, professional, and leadership career aspirations (including motivations, efficacies, and intentions) can be measured independently, that these career dimensions are independent of vocational interests, and that they are to some degree viewed as competing career alternatives. We also show that EPL motivation profiles can operationalize the boundaryless and protean career concepts. Individuals concurrently high in entrepreneurial, professional, and leadership career motivations, and those high in entrepreneurial and leadership motivations are highest in boundaryless and self-directed career attitudes, while those primarily motivated for professional careers hold the most traditional career attitudes. We conclude by discussing the potential of the framework for understanding human resource issues at organizational and national levels and for enhancing the study of entrepreneurship, professionalism, and leadership.  相似文献

利用眼动分析技术,通过设置不同难度和分值的计算项目,探讨了在有时间压力下学习者的学习时间分配。结果发现:(1)在首次项目选择上,学习者优先选择学习率最高的项目;(2)在学习过程中,学习者的项目选择次序也是根据学习率由高到低。总之,在学习时间分配上,如果需要权衡难度与分值,学习者会考虑单位时间的获益,也就是以学习率为议程的主要依据。研究不仅利用眼动分析技术证实了基于议程的学习时间分配模型,而且进一步揭示了学习率是设置学习时间分配议程的重要依据。  相似文献

执行功能缺陷是网络成瘾发生、维持和复发的原因之一,以往研究侧重于探讨网络成瘾者注意控制、反应抑制等执行功能成分的损伤状况,而其记忆抑制状况尚不清楚。本研究通过考察网络成瘾大学生的提取诱发遗忘(RIF)来探讨其记忆抑制的特点及RIF的产生机制。结果发现:低网络成瘾个体在高项目竞争强度下表现出显著的RIF,在低项目竞争强度下未产生;高网络成瘾个体在低项目竞争强度下表现出显著的RIF,在高项目竞争强度下未产生。结果表明网络成瘾大学生的记忆抑制能力受损严重,其在低项目竞争强度下易受相关代价与效益问题(CCB)影响而产生干扰性RIF。  相似文献

逻辑学以及形式语义学对汉语连动结构的研究一般都停留在一阶逻辑的层面上,即通过一阶逻辑中的形式化方法给出连动结构的形式化构造。但是在对不同类型连动结构进行更为深入的研究时,一阶逻辑这一工具就显的不够了。本文中,作者将以因果型连动结构为研究对象,利用一阶模态逻辑为其构建形式系统并尝试给出因果型连动结构和途径–目的型连动结构之间的区别和联系。  相似文献

Personality is hypothesized to have direct and indirect effects on health-related quality of life (HRQoL) through the mediating role of perceived occupational stressors. This hypothesized model was tested with Chinese judges, individuals characterized by high occupational stress. In this cross-sectional study, 330 judges undergoing professional training at the Shandong Judge Training Institute completed questionnaires assessing their personality (Big Five Inventory, BFI), perceived occupational stressors (Occupational Role Questionnaire, ORQ), and HRQoL (Medical Outcomes Study Short-Form Health Survey, SF-36). The proposed model was tested using structural equation modelling (SEM) approaches. The SEM analysis showed a good fit of the data to the hypothesized model(x 2/df = 1.52, P?P?Neuroticism also had a negative indirect effect (?0.18, P?P?P?相似文献

The transition to university can be stressful for first-year university students. Despite the fact where the feeling of worry is a shared symptom by various mental health issues, there is a lack of studies that investigate into this matter. As worry is a domain-specific construct, there is a need for a valid and reliable measure of worry specifically for university students. Hence, this study aimed to evaluate the psychometric properties of the Student Worry Scale (SWS), particularly in terms of its validity and reliability. For this purpose, the current study recruited a sample of 295 first-year students to evaluate the psychometric properties of SWS. Exploratory factor analysis yielded a five-factor structure of SWS, which explained 55.7% of the total variance. The yielded five factors were general worries, financial-related concerns, significant other’s well-being, academic concerns, and social adequacy concerns. Inter-correlations between the five factors were all significant (r ranged between 0.395 and 0.625). The SWS demonstrated good internal consistency in this study (Cronbach’s alpha ranged between 0.786 and 0.941). Overall, the SWS is psychometrically evidenced to be a reliable and valid content-based worry measure specifically for university students.  相似文献

The isolated elements and variability effects of cognitive load theory were used to alter the element interactivity of Chinese characters when instructing novice learners (72 overseas students at a Chinese university) in writing characters using worked examples-practice procedures. A group of characters with more than eight strokes was disassembled into three individual components. Students were required to trace examples and practice writing of either similar sequences of isolated components followed by integrated components of full characters (Isolated–Integrated sequences); variable sequences of isolated followed by integrated components (Variability–Integrated sequences); or conventional Integrated–Integrated sequences of full characters. It was hypothesized that the fully integrated stroke-movements form of example-practice sequences would result in less learning due to a greater cognitive load. The results demonstrated that the participants in both the Isolated–Integrated and Variable–Integrated groups performed significantly better than the Integrated–Integrated group with the Variable–Integrated group outperforming the Isolated–Integrated group.  相似文献

The aim of this study was to determine the effects of psychological interventions (e.g. cognitive restructuring, relaxation) on physiological and psychological health in osteoarthritis patients. A systematic literature search was done using PubMed, Embase, PsycINFO, Web of Science, China National Knowledge Infrastructure, and Wanfang Database through November 2016. Studies were included if they used a randomized controlled trial designed to explore the effects of psychological interventions in osteoarthritis patients. Two independent authors assessed the methodological quality of the trials using criteria outlined by Jadad et al. Meta-analysis was done with the Revman5.0. Twelve randomized controlled trials, including 1307 osteoarthritis patients, met the study inclusion criteria. Meta-analysis showed that psychological interventions could reduce the levels of pain [standard mean difference (SMD) ?0.28, 95% CI ?0.48, ?0.08, P-value 0.005)] and fatigue (SMD ?0.18, 95% CI ?0.34, ?0.01, P-value 0.04). In addition, psychological interventions significantly improved osteoarthritis patients’ self-efficacy (SMD 0.58, 95% CI 0.40, 0.75, P-value 0.00) and pain coping (MD 1.64, 95% CI 0.03, 3.25, P-value 0.05). Although the effects on physical function, anxiety, depression, psychological disability were in the expected direction, they were not statistically significant. In conclusion, the role of psychological interventions in the management of osteoarthritis remains equivocal. Some encouraging results were seen with regard to pain, pain coping, self-efficacy, and fatigue. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question.  相似文献
