This article presents a provocative perspective on creativity with two controversial assertions. First, it challenges the conventional view of the creator as an innovative person, by promoting the notion of the dogmatic creator. Second, it argues that nice people are not creative, and creative people are not nice. An integrative review of the empirical literature on culture, creativity, and conflict ensues. In the process, four sets of hypotheses are developed which are embedded in two theoretical models of behavior. In Theoretical Model A, it is postulated that cultural individualism-collectivism has a positive causal impact on independent self-construal (Hypothesis 1A). In turn, independent self-construal is posited to have a positive causal impact on positive perception of conflict (Hypothesis 2A), confrontational conflict style (Hypothesis 3A), and creative behavior (Hypothesis 4A). In Theoretical Model B, it is postulated that cultural individualism-collectivism has a negative causal impact on interdependent self-construal (Hypothesis 1B). In turn, interdependent self-construal was postulated to have a positive causal impact on negative perception of conflict (Hypothesis 2B), non-confrontational conflict style (Hypothesis 3B), and conforming behavior (Hypothesis 4B). One-hundred-eighty-six university students in Singapore and 158 students in Australia responded to a survey, which consisted of various scales tapping the constructs in these two theoretical models of behavior. SEM analyses using LISREL 8.0 provided empirical support for both models of behavior. Based on these findings, several points are raised. First, creativity should not be perceived in a naïve manner. Second, there is an urgent need to assist parents, teachers, and employers to deal with creative individuals. Finally, since creativity is a cultural phenomenon, the cultural context must be made amenable for this type of behavior.  相似文献

We consider a two-agent scheduling problem on a single machine, where the objective is to minimize the total completion time of the first agent with the restriction that the number of tardy jobs of the second agent cannot exceed a given number. It is reported in the literature that the complexity of this problem is still open. We show in this paper that this problem is NP-hard under high multiplicity encoding and can be solved in pseudo-polynomial time under binary encoding. When the first agent's objective is to minimize the total weighted completion time, we show that the problem is strongly NP-hard even when the number of tardy jobs of the second agent is restricted to be zero.  相似文献

This study examined 58 sexually abused children referred for clinical psychological services in 1999 in Hong Kong and compared the characteristics and disclosure patterns between those with multiple incidents of abuse and those with single incident. The former group was more likely to have been abused by a family member, took a longer time to disclose, and was more often abused in contexts where the abusers had control and power. Over 40% of subjects also reported presence of other persons during abuse. Myths and misconceptions among professionals are highlighted. Implications on future service development and training needs in child protection are discussed.  相似文献

The purpose of this study is to evaluate the newly developed clinical protocol "Goal Attainment Program" to assist psychiatric in-patients in Hong Kong to formulate realistic life goals, with a view to shortening their length of stay and motivating them to join in work rehabilitation. The Goal Attainment Scale for Psychiatric In-patients was validated and used to evaluate the change in life goals after attending the four-session Goal Attainment Program. The validated 10-item version of the Goal Attainment Scale for Psychiatric In-patients (GASPI-10) was found to have good inter-rater reliability (rho_{I} ranged from 0.64 to 0.88,p < 0.01; N = 26) and internal consistency (alpha of rater 1 = 0.92, rater 2 = 0.87, N = 26). Twenty-five chronic psychiatric in-patients of Castle Peak Hospital in Hong Kong completed the Goal Attainment Program and were assessed using a pre and post-test quasi-experimental design. The T-score computation of GASPI-10 indicated that 92% of patients showed improvement in goal attainment. Some 92% of patients stated that they were willing to leave hospital, and 72% of participants planned to seek paid employment upon discharge after completion of the program. The overall results of this study verified the effectiveness of the Goal Attainment Program in instilling hope in chronic patients with schizophrenia and the use of the Goal Attainment Scale in documenting patients' progress.  相似文献

Studies on women's sexuality in China since 1980: a critical review   总被引:1,自引:0,他引:1  
Over the last 20 years, women's sexuality has become one of the most written about and intensely debated subjects in sexology, sociology and women's studies in mainland China. From these studies, one can trace the development of academic discourse on women's sexuality through three distinct phases: from a predominantly medical discourse, to the use of survey methods to investigate women's real experiences, and finally to a phase in which Western theories have become increasingly influential. Each phase features a distinct stereotype of woman. The implications of this review for sexual research in China will also be discussed.  相似文献

Many organizations that were once quality leaders have had challenges sustaining high‐quality performance. Although research has examined frameworks and concepts that lead to high‐quality performance, few studies examine how to sustain high‐quality performance. Sustaining performance may require additional capabilities from what it takes to achieve it. Drawing on quality management literature, organizational resilience literature, and the theory of dynamic capabilities in the strategy literature, this study empirically investigates the effects of four capabilities that help sustain high‐quality performance. The analysis shows that capabilities in improvement, innovation, sensing weak signals, and responsiveness all help sustain high‐quality performance. This suggests that what it takes to achieve high‐quality performance is different, in part, from what it takes to sustain it. The data comes from a survey of 147 manufacturing business units. The analysis shows that the relative benefits of these capabilities may depend on the level of competitive intensity and environmental uncertainty. The findings provide empirical support for a theoretical model and practical guidance for sustaining quality performance.  相似文献

Testing for the difference in the strength of bivariate association in two independent contingency tables is an important issue that finds applications in various disciplines. Currently, many of the commonly used tests are based on single-index measures of association. More specifically, one obtains single-index measurements of association from two tables and compares them based on asymptotic theory. Although they are usually easy to understand and use, often much of the information contained in the data is lost with single-index measures. Accordingly, they fail to fully capture the association in the data. To remedy this shortcoming, we introduce a new summary statistic measuring various types of association in a contingency table. Based on this new summary statistic, we propose a likelihood ratio test comparing the strength of association in two independent contingency tables. The proposed test examines the stochastic order between summary statistics. We derive its asymptotic null distribution and demonstrate that the least favorable distributions are chi-bar distributions. We numerically compare the power of the proposed test to that of the tests based on single-index measures. Finally, we provide two examples illustrating the new summary statistics and the related tests.  相似文献

The emerging field of cancer radiomics endeavors to characterize intrinsic patterns of tumor phenotypes and surrogate markers of response by transforming medical images into objects that yield quantifiable summary statistics to which regression and machine learning algorithms may be applied for statistical interrogation. Recent literature has identified clinicopathological association based on textural features deriving from gray-level co-occurrence matrices (GLCM) which facilitate evaluations of gray-level spatial dependence within a delineated region of interest. GLCM-derived features, however, tend to contribute highly redundant information. Moreover, when reporting selected feature sets, investigators often fail to adjust for multiplicities and commonly fail to convey the predictive power of their findings. This article presents a Bayesian probabilistic modeling framework for the GLCM as a multivariate object as well as describes its application within a cancer detection context based on computed tomography. The methodology, which circumvents processing steps and avoids evaluations of reductive and highly correlated feature sets, uses latent Gaussian Markov random field structure to characterize spatial dependencies among GLCM cells and facilitates classification via predictive probability. Correctly predicting the underlying pathology of 81% of the adrenal lesions in our case study, the proposed method outperformed current practices which achieved a maximum accuracy of only 59%. Simulations and theory are presented to further elucidate this comparison as well as ascertain the utility of applying multivariate Gaussian spatial processes to GLCM objects.  相似文献
