大学生创造性人格调查分析

21世纪人才素质的核心是创造性素质。创造性素质 ,主要指一个人的创新意识、创造性思维能力以及创造性人格品质。本研究利用卡氏十六种人格因素测验量表 (16 PF)对北京邮电大学本科生的创造性人格进行测试 ,分析表明影响人的创造力的因素是复杂的。创造性是可以通过教育进行培养的 ,关键是要通过教育改革创造条件 ,允许和鼓励人的个性的发展     

Adapting by calibration the sample size of a phase III trial on the basis of phase II data

The problem of estimating the sample size for a phase III trial on the basis of existing phase II data is considered, where data from phase II cannot be combined with those of the new phase III trial. Focus is on the test for comparing the means of two independent samples. A launching criterion is adopted in order to evaluate the relevance of phase II results: phase III is run if the effect size estimate is higher than a threshold of clinical importance. The variability in sample size estimation is taken into consideration. Then, the frequentist conservative strategies with a fixed amount of conservativeness and Bayesian strategies are compared. A new conservative strategy is introduced and is based on the calibration of the optimal amount of conservativeness – calibrated optimal strategy (COS). To evaluate the results we compute the Overall Power (OP) of the different strategies, as well as the mean and the MSE of sample size estimators. Bayesian strategies have poor characteristics since they show a very high mean and/or MSE of sample size estimators. COS clearly performs better than the other conservative strategies. Indeed, the OP of COS is, on average, the closest to the desired level; it is also the highest. COS sample size is also the closest to the ideal phase III sample size M_I, showing averages and MSEs lower than those of the other strategies. Costs and experimental times are therefore considerably reduced and standardized. However, if the ideal sample size M_I is to be estimated the phase II sample size n should be around the ideal phase III sample size, i.e. n?2M_I/3. Copyright © 2010 John Wiley & Sons, Ltd.     

Electricity consumption prediction with functional linear regression using spline estimators

A functional linear regression model linking observations of a functional response variable with measurements of an explanatory functional variable is considered. This model serves to analyse a real data set describing electricity consumption in Sardinia. The interest lies in predicting either oncoming weekends’ or oncoming weekdays’ consumption, provided actual weekdays’ consumption is known. A B-spline estimator of the functional parameter is used. Selected computational issues are addressed as well.     

人格特质对授权感知的调节效应研究

一、引言 传统的授权理论认为,授权就是将权利分派给其他人以完成特定活动的过程,也就是说,把决策权从组织的一个层级移交到另一个层级(Astly,1984)[1].现代授权理论则认为,授权的本质在于尽可能释放员工的知识、经验和动力,增加员工自我效能感,消除员工"无权"的感觉(Arad & Drasgow ,1994;Conger & Kanungo,1988;Spreitzer,1996).正如Lee和Koh(2001)指出的,授权实际上有两个完全不同的方面,一方面是主管给下属授权的"行为",另一方面是下属感知这种授权行为的"心理状态",即授权感知.

教育脱贫视阈下边境乡村学前教育发展的田野研究 ——以云南省怒江傈僳族自治州为例

教育是减少贫困的重要手段。学前教育作为基础教育的基础,其在教育脱贫功效发挥的过程中具有特殊的贡献。云 南怒江州是我国“三区三州”少数民族深度贫困地区之一。近几年,怒江州学前教育在办园规模、幼儿园毛入园率等方面取得 了巨大的进展。但是师资数量短缺、教师队伍专业素养偏低、教学小学化严重、在园活动保育环节不健全等突出问题,制约着 乡村幼儿园保教质量的提升,进而会影响教育脱贫整体功效的发挥。提升少数民族深度贫困地区乡村学前教育质量,既要在 物质层面继续完善办园条件,更要着力于尽快在师资层面建立优质教师补充机制,比如试行“少数民族深度贫困地区学前免费 师范生计划”,同时需要加快补充配齐较为优质的临时保教人员,加大在职幼儿园教师专业培训。

寻求价值均衡：现代和谐宪政建构的必由之路

审视现代西方宪政制度运行所面临的诸多问题和价值冲突,本文认为,寻求政治价值的某种均衡与和谐,是现代宪政发展的必然选择。寻求政治价值均衡既是现代社会多元利益关系相互博弈的合理抉择,也有着厚实的理论基础。从政府权力运用这一维度来考察,实现政治价值均衡的路径主要是解决公共权力"有限"与政府"有为"之间的关系问题。解决权力"有限"的核心是建构多元化的、相互补充的有机控权机制;实现政府"有为"的基础是塑造有效政府,保障政府治理在实现公共性、公平性、回应性、开放性、合作性、凝聚性等方面积极有为,增进社会和谐。     

新论土家语的判断句

土家语的判断句,归纳起来只有肯定判断和否定判断两大类,其中又有隐性判断和显性判断的区别,判断形式多种多样,判断词也极为丰富。说土家语“无判断词”和“判断动词是从汉语里吸收的”是以偏概全,应予纠正。     

Adaptable Careers: Maximizing Less and Exploring More

Today, young adults are expected to decide between educational, vocational, and job options and to make the best choice possible. Career literatures emphasize the importance of young adults' career decision making but also acknowledge the problems related to making these decisions. The authors argue that career counselors could support clients' intuitive processing of career information and help their clients to develop a positive and flexible view of the self and the environment while diminishing concerns about accountability for and irreversibility of career decisions. The authors argue that career adaptability rather than decision making should become the focal concept of career theory and practice.
