余英时先生《朱熹的历史世界》一书重构两宋(尤其是南宋)政坛面貌,旁征博引,新见迭出,深得学界好评。然而通读全书,作者对若干史料的运用,似不无令人生疑之处。书中史料处理的疑点。主要可分为:字词含义、语段脉络、史料性质、推论程序四类。 相似文献

This study explores the consistency between objective indicators and subjective perceptions of quality of life in a ranking
of survey data for cities and counties in Taiwan. Data used for analysis included the Statistical Yearbook of Hsiens and Municipalities
and the Survey on Living Conditions of Citizens in Taiwan, both given for the year 2000. The Quality of life was examined
in seven domains: medical services, domestic finances, work, education, leisure, public safety, and environmental quality.
Subjective and objective rankings for each domain of quality of life for 23 areas (some areas are cities and some are counties)
are compared. Analysis by means of nonparametric correlation coefficients indicates that there is no significant correlation
between objective indicators and subjective perceptions, except in Education and Environmental Quality. Objective indicators
of Environmental Quality (air pollution and garbage) are positively correlated with subjective satisfaction with residential
environment. But inexplicably, higher levels of literacy and educational achievement are negatively correlated with satisfaction
with the educational system. It may be considered that disparity in either average objective conditions or in average subjective
perceptions may not adequately depict quality of life differences.

The purpose of this study was to examine the performance of the Thai-version of WHOQOL-BREF in assessing the quality of life
(QoL) among Thai college students. The psychometric properties of WHOQOL-BREF were assessed in this study. The self-administered
WHOQOL-BREF questionnaire was applied. A total of 407 Thai college students (male age = 20.5 ± 1.2; female age = 20.5 ± 1.2)
participated in this study. Item-response distributions, internal consistency reliability, discriminant validity, criterion-related
validity and construct validity through confirmatory analysis were analyzed. The findings indicate that the WHOQOL-BREF had
acceptable internal consistency (α = 0.73–0.83 across four domains), all items highly correlated with corresponding domain
scores (r = 0.53–0.80), the indices of a two-order confirmatory factor analysis (CFA) demonstrate that the data fit the model well
with allowing covary of error variances of some items, all items had good property of criterion-related validity and item
discrimination and, all three domain scores except the social relationship domain had significant associations with overall
QoL or general health. The results suggest that the WHOQOL-BREF was reliable and valid to health professionals in the assessment
of the QoL of college-based Thai youth, but some unsuitable items may be deleted in future studies. 相似文献

上海市人口老龄化:现状、影响及对策思考 总被引:2,自引:1,他引:1
人口老龄化已成为当今世界各国经济发展过程面临的共同性话题,就上海而言.未来上海市人口老龄化带来的影响已逐渐凸显,人口老龄化带来的养老金匮乏,劳动力不足以及社区为老服务发展滞后的矛盾已开始成为制约上海市经济发展的瓶颈,老龄化带来的影响将在未来很长一段时间内长期存在.缓解人口老龄化带来的影响以及寻求可行性办法解决老龄化人口的赡养问题已成为政府和社会必须要解决的问题。 相似文献

建国以来,我国出生率发生了重大转变,随着90年代以来人口出生率的逐年下降,我国高等教育将面临学生数量下滑趋势,未来高等院校将会出现生源不足的困境。但是,由于目前我国高等教育入学率还比较低,加之政府财政时高等教育支持的力度也还有很大提升空阅,因此,尽管出生率会不断下降,但对高等院校整体上生存不会受太大的影响。 相似文献

This paper analyses the importance of evaluating the various components of the programmes or actions carried out by education organisations. It highlights the need to assess the impact of the intervention on the organisation and consider how changes are consolidated over time in interaction with the context. We propose an impact evaluation model and as an example have chosen the implementation of Quality Management Systems in schools. The paper analyses the results obtained in 40 schools in three regions (Spanish Autonomous Communities) with varying levels of implementation. The results show overall impact on these education centres as the teachers and management teams of the centres perceive it. This impact is more evident in some of the dimensions considered in the study than in others. The results also confirm the differences between regional contexts. 相似文献

ABSTRACTService user involvement (SUI) in social work education has gained widespread attention in Europe and other continents. Nevertheless, experiences on including service users in social work education have not been reported from Germany or other German-speaking countries to date. This paper reports preliminary experiences with implementing SUI in a bachelor’s programme of social work in a German University of Applied Sciences. The main goals of the current paper are (1) to provide a background for implementing service user approaches in Germany by introducing the structure of social work education in Germany; (2) to report experiences from a weekend seminar where service users worked together with students of social work in the framework of a curriculum of a German University of Applied Sciences and (3) to formulate some implications of these experiences for SUI across Europe. The main results were that introducing service user involvement into a German curriculum of social work is possible but needs careful reflection and planning. Experiences gathered in the weekend seminar with service users were encouraging for service users, students and teachers. We conclude that systematically implementing SUI into German curricula of social work is important. 相似文献

The gist of the quickest change-point detection problem is to detect the presence of a change in the statistical behavior of a series of sequentially made observations, and do so in an optimal detection-speed-versus-“false-positive”-risk manner. When optimality is understood either in the generalized Bayesian sense or as defined in Shiryaev's multi-cyclic setup, the so-called Shiryaev–Roberts (SR) detection procedure is known to be the “best one can do”, provided, however, that the observations’ pre- and post-change distributions are both fully specified. We consider a more realistic setup, viz. one where the post-change distribution is assumed known only up to a parameter, so that the latter may be misspecified. The question of interest is the sensitivity (or robustness) of the otherwise “best” SR procedure with respect to a possible misspecification of the post-change distribution parameter. To answer this question, we provide a case study where, in a specific Gaussian scenario, we allow the SR procedure to be “out of tune” in the way of the post-change distribution parameter, and numerically assess the effect of the “mistuning” on Shiryaev's (multi-cyclic) Stationary Average Detection Delay delivered by the SR procedure. The comprehensive quantitative robustness characterization of the SR procedure obtained in the study can be used to develop the respective theory as well as to provide a rational for practical design of the SR procedure. The overall qualitative conclusion of the study is an expected one: the SR procedure is less (more) robust for less (more) contrast changes and for lower (higher) levels of the false alarm risk. 相似文献

It is well known that in finance variances and covariances of asset returns move together over time. Recently, much interest has been aroused by an approach involving the use of the realized covariance (RCOV) matrix constructed from high-frequency returns as the ex-post realization of the covariance matrix of low-frequency returns. For the analysis of dynamics of RCOV matrices, we propose the generalized conditional autoregressive Wishart (GCAW) model. Both the noncentrality matrix and scale matrix of the Wishart distribution are driven by the lagged values of RCOV matrices, and represent two different sources of dynamics, respectively. The GCAW is a generalization of the existing models, and accounts for symmetry and positive definiteness of RCOV matrices without imposing any parametric restriction. Some important properties such as conditional moments, unconditional moments, and stationarity are discussed. Empirical examples including sequences of daily RCOV matrices from the New York Stock Exchange illustrate that our model outperforms the existing models in terms of model fitting and forecasting. 相似文献
