Research on the structure of personality in middle childhood, while advancing, is still in the early stages of development. In this study, we employed a group of 1563 twins to elucidate the hierarchical structure of personality in middle childhood and provide connections to established personality traits in adult populations. Our results provide evidence for a higher-order structure of personality in middle childhood that maps on to recent findings in adult populations supporting hierarchical relationships among 2-, 3-, 4-, and 5-factor models of personality. In addition, primary higher-order personality traits rated by parents at age 11 showed substantial predictive validity for analogous traits rated by self at age 17. We discuss our results within the context of developing a convergent hierarchical taxonomy of personality in middle childhood and the importance of multi-informant investigations.  相似文献

人格与智力是个体差异中相互关联的两个重要方面,人格随智力水平的提高而不断分化,智力影响了特定人格维度之间的相关。尽管人格分化的智力假设尚未获得一致性的证据,但它却暗示了智力对人格结构的潜在影响。由于人格测量工具的信度和效度可能因受测者的能力水平而异,因此未来的研究应在使用统一测量工具的基础上,尽量扩大被试的能力范围,采用多重评估或集合评定的方法,使人格测量真正独立于受测者的认知能力。  相似文献

修订BTL-QZ-V1.1气质测试系统。对519名12—21岁男女学生进行了测量。结果发现:神经系统特性具有年龄差异,随年龄增长兴奋性、抑制性增强,灵活性、稳定性增高;12~14岁是其快速增长期,14~18岁为慢速增长期,18岁后为稳定期;神经系统的兴奋性、抑制性具有性别差异,男生强于女生;可将气质类型划分为10种,年龄和性别不影响气质类型的分布;除灵活性外,神经系统兴奋性、抑制性和稳定性的重测信度系数在0.6~0.8之间,且达到显著性水平;以80·8神经类型量表为效标,所得相关系数达中等程度。提示BTL-QZ-V1.1气质测试系统的评定需按年龄和性别分组进行,建立的分组标准较为准确科学,信度、效度较高,可以广泛应用。  相似文献

The experience with genetically modified foods has been prominent in motivating science, industry and regulatory bodies to address the social and ethical dimensions of nanotechnology. The overall objective is to gain the general public’s acceptance of nanotechnology in order not to provoke a consumer boycott as it happened with genetically modified foods. It is stated implicitly in reports on nanotechnology research and development that this acceptance depends on the public’s confidence in the technology and that the confidence is created on the basis of information, education, openness and debate about scientific and technological developments. Hence, it is assumed that informing and educating the public will create trust, which will consequently lead to an acceptance of nanotechnology. Thus, the humanities and social sciences are seen as tools to achieve public acceptance. In this paper, the author argues that this is a narrow apprehension of the role of the humanities and social sciences. The humanities and social sciences have a critical function asking fundamental questions and informing the public about these reflections. This may lead to scepticism, however, the motivation for addressing the social and ethical dimensions of nanotechnology should not be public acceptance but informed judgement. The author illustrates this critical function by discussing the role, motivation and contribution of ethics as an example. Lastly, the author shows that a possible strategy for incorporating the humanities and the social sciences into nanotechnology research and development is Real-Time Technology Assessment, where the purpose is to integrate natural science and engineering investigations with ethical, legal and social science from the outset.

There is no agreement on how nanoethics should proceed. In this article I focus on approaches for discerning ethical issues in nanotechnology, which is as of yet one of the most difficult and urging tasks for nanoethics. I discuss and criticize two existing approaches for discerning ethical issues in nanotechnology and propose a network approach as alternative. I discuss debates in nanoethics about the desirable role of ethics in nanotechnological development and about the newness of ethical issues in nanotechnology. On basis of a critical analysis of both debates, I formulate a number of desiderata for a method for discerning ethical issues in nanotechnology and argue that the network approach that my colleagues and I have developed for ethical issues in research and development networks is also appropriate in nanotechnology.

This article deals with perhaps the greatest problem of our time, the ever increasing world’s neglected and ignored poor. I argue here that economic development can be cultivated by endogenously from the bottom up (implemented through entrepreneurship) and that the economic output to be exported globally. Unique characteristics of entrepreneurs and their contribution to the economy can make it possible for third world countries to grow their economies faster and provide economic means to enhance social, health, and environmental well-being (basic dimensions of quality of life), along with products and services that the poor need in these countries. Developing countries need to develop entrepreneurial cultures for economic growth and enhanced quality of life. But, sheer presence and positive performance is not totally adequate since the above mentioned dimensions are only necessary but not sufficient conditions. Note: This paper draws from A. Coskun Samli (2008), “International Entrepreneurship and Quality of Life,” in W. E. Kilbourne and J. D. Middelstaedt (eds), The 33rd Annual Meeting of the Macro-Marketing Society 2008, 109–116.  相似文献

The WOrk-reLated Flow inventory (WOLF) measures flow at work, defined as a short-term peak experience characterized by absorption, work enjoyment, and intrinsic work motivation. Results of Study 1 among 7 samples of employees (total N = 1346) from different occupational groups offer support for the factorial validity and reliability of the WOLF. Study 2 examined the validity of the WOLF in more detail among some of the samples. Positive correlations between a general flow index and the three flow dimensions confirm the convergent validity of the WOLF. In addition, the findings of Study 2 provide evidence for the construct and predictive validity of the WOLF using five job characteristics as predictors of flow, and other-ratings of performance as outcomes.  相似文献

Do 18-month-olds understand that an agent's false belief can be corrected by an appropriate, though not an inappropriate, communication? In Experiment 1, infants watched a series of events involving two agents, a ball, and two containers: a box and a cup. To start, agent1 played with the ball and then hid it in the box, while agent2 looked on. Next, in agent1's absence, agent2 moved the ball from the box to the cup. When agent1 returned, agent2 told her "The ball is in the cup!" (informative-intervention condition) or "I like the cup!" (uninformative-intervention condition). During test, agent1 reached for either the box (box event) or the cup (cup event). In the informative-intervention condition, infants who saw the box event looked reliably longer than those who saw the cup event; in the uninformative-intervention condition, the reverse pattern was found. These results suggest that infants expected agent1's false belief about the ball's location to be corrected when she was told "The ball is in the cup!", but not "I like the cup!". In Experiment 2, agent2 simply pointed to the ball's new location, and infants again expected agent1's false belief to be corrected. These and control results provide additional evidence that infants in the second year of life can attribute false beliefs to agents. In addition, the results suggest that by 18 months of age infants expect agents' false beliefs to be corrected by relevant communications involving words or gestures.  相似文献
