公私合营模式在医疗领域中应用的探讨——以镜湖医院在澳门的发展为例

在阐述公私合营模式定义的基础上,以澳门为典型案例介绍了该模式在医疗领域中的具体应用,并从理论上对中国内地实施公私合营的医院管理模式提出相关建议.中国内地在日后推行这种医院管理模式时应特别注意明确私立医疗机构的社会责任和使命、完善相关扶持政策和强化审批与监管制度.     

运动知识与概念知识概率学习下的内隐学习效应

研究采用序列学习范式,用反应时间接测量被试的内隐知识,问卷以及再认成绩直接测量被试的外显知识,并采用PDP测量被试的意识与无意识贡献率.结果表明:(1)无RSI条件下能习得一定的无意识知识,而在有RSI条件下习得的知识大部分能被外显地意识到.(2)当内隐序列学习中既包含运动知识又包含概念知识时,无RSI条件下易获得运动知识;而在有RSI条件下,如果时间充分且能协调注意资源,运动知识和概念知识均能有效学习.     

Supporting Generative Thinking About the Integer Number Line in Elementary Mathematics

This report provides evidence of the influence of a tutorial “communication game” on fifth graders’ generative understanding of the integer number line. Students matched for classroom and pretest score were randomly assigned to a tutorial (n = 19) and control group (n = 19). The tutorial group students played a 13-problem game in which student and tutor each were required to mark the same position on a number line but could not see one another's activities. To resolve discrepant solutions, tutor and student constructed agreements about number line principles and conventions to guide subsequent placements. Pre-/posttest contrasts showed that (a) tutorial students gained more than controls and (b) agreement use predicted gain. Analyses of micro-constructions during play revealed properties of student learning trajectories.     

The Two Facets of Conscientiousness: Interaction of Achievement Orientation and Dependability in Predicting Managerial Execution Effectiveness

The two facets of conscientiousness, achievement orientation and dependability, have frequently been found to relate to performance outcomes in different manners. However, little research has examined the interaction between these two facets. In this article we examine the main effect and interaction of these two facets in predicting managerial execution. Using two separate samples of Executive Master of Business Administration (EMBA) students (N?=?167 in Study 1 and N?=?269 in Study 2), we found that dependability but not achievement orientation had a direct positive association with coworkers’ rating on managerial execution. More important, there was an interaction effect between these two facets. Dependability was strongly associated with execution among managers with high achievement orientation, but not among managers with low achievement orientation.     

Twinning in cryomilled nanocrystalline Mg powder

Nanocrystalline (nc) Mg powder was synthesized via cryomilling. Extension twins were identified with high-resolution transmission electron microscopy in the cryomilled powders and the study presents the first evidence of twinning in unalloyed nc Mg. The formation of twins in the nc Mg is attributed to a high strain rate, the low (cryogenic) temperature and high local shear stresses present around the grain boundaries during deformation by cryomilling.     

Differentiating core and co-opted mechanisms in calculation: The neuroimaging of calculation in aphasia

The role of language in exact calculation is the subject of debate. Some behavioral and functional neuroimaging investigations of healthy participants suggest that calculation requires language resources. However, there are also reports of individuals with severe aphasic language impairment who retain calculation ability. One possibility in resolving these discordant findings is that the neural basis of calculation has undergone significant reorganization in aphasic calculators. Using fMRI, we examined brain activations associated with exact addition and subtraction in two patients with severe agrammatic aphasia and retained calculation ability. Behavior and brain activations during two-digit addition and subtraction were compared to those of a group of 11 healthy, age-matched controls. Behavioral results confirmed that both patients retained calculation ability. Imaging findings revealed individual differences in processing, but also a similar activation pattern across patients and controls in bilateral parietal cortices. Patients differed from controls in small areas of increased activation in peri-lesional regions, a shift from left fronto-temporal activation to the contralateral region, and increased activations in bilateral superior parietal regions. Our results suggest that bilateral parietal cortex represents the core of the calculation network and, while healthy controls may recruit language resources to support calculation, these mechanisms are not mandatory in adult cognition.     

阻塞性睡眠呼吸暂停低通气综合征与脑卒中

阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)作为一种脑卒中独立的危险因素已经广泛受到重视,是脑卒中、冠心病、高血压、充血性心力衰竭等心脑血管疾病的一个主要发病因素.OSAHS引起的频繁血氧饱和度下降和夜间睡眠结构紊乱对心脑血管系统产生严重的危害.本综述主要讨论OSAHS对脑卒中患者的影响和对此类患者的治疗.了解OSAHS和脑卒中之间的联系对于脑卒中的一、二级预防具有重要的意义.     

Research Productivity and Performance of Journals in the Creativity Sciences: A Bibliometric Analysis

A bibliometric approach was employed to analyze the research productivity and performance of creativity studies between 1965 and 2012. A dataset was constructed using all publications and citations retrieved from four key journals that publish creativity research: Journal of Creative Behavior (JCB), Gifted Child Quarterly (GCQ), Creativity Research Journal (CRJ), and Psychology of Aesthetics, Creativity, and the Arts (PACA). Major findings in this study include: (a) During the study period, the four journals have published 1,891 articles on creativity and they have been cited 11,709 times; (b) the impact factors of the four journals increased from lower than .50 in 2002 to over 1.0 in 2012; in 2012 PACA had the highest impact factor, followed by CRJ; (c) JCB published the most creativity papers and CRJ had the most citations; (d) about a third of the articles published in the four journals have never been cited. Implications for the field of creativity are discussed.     

“Faith Maturity Scale” for Chinese: A Revision and Construct Validation

Using a large sample of Chinese Christians (n = 2,196), we examined the internal structure, reliability, and validity of the Faith Maturity Scale (FMS). Despite its being developed in North America, and for a mainline Protestant population, the FMS was shown to have validity among non-Western, non-mainline Protestants. There is convergent validity with self-reported religious practices and a belief measure of religiosity. Our analyses also confirmed good construct validity with the Big Five personality dimensions, social axioms, attributional style, and quality of life. FMS remained associated with religious practices and high quality of life after personality was statistically controlled. Findings supported that the Chinese version of the FMS assesses the same theoretical construct as does the original scale and that the distinction between the vertical and horizontal dimensions of faith maturity is meaningful.
