文化视域下社会主义核心价值体系对高校德育的引领作用

高校德育是社会主义核心价值体系建设的重要基础工程，社会主义核心价值体系在德育中占有重要地位，而这个重要地位是在引领中实现的。高校教育德育工作者应当结合大学生的实际状况，从文化建设的视觉，领会社会主义核心价值体系对高校德育的引领作用，进而有的放矢地开展德育，培养大学生成为理想远大、热爱祖国的人，追求真理、勇于刨新的人，德才兼备、全面发展的人，视野开阔、胸怀宽广的人，知行统一、脚踏实地的人。     

零膨胀计数数据的联合建模及变量选择

零膨胀计数数据破坏了泊松分布的方差-均值关系，可由取值服从泊松分布的数据和取值为零(退化分布)的数据各占一定比例所构成的混合分布所解释。本文基于自适应弹性网技术， 研究了零膨胀计数数据的联合建模及变量选择问题.对于零膨胀泊松分布，引入潜变量，构造出零膨胀泊松模型的完全似然, 其中由零膨胀部分和泊松部分两项组成.考虑到协变量可能存在共线性和稀疏性，通过对似然函数加自适应弹性网惩罚得到目标函数,然后利用EM算法得到回归系数的稀疏估计量，并用贝叶斯信息准则BIC来确定最优调节参数.本文也给出了估计量的大样本性质的理论证明和模拟研究，最后把所提出的方法应用到实际问题中。     

Stress and job satisfaction in mammography radiographers

Abstract

Previous research suggests that substantial numbers of health professionals experience undue levels of occupational stress. Little is yet known, however, about a recently established specialized group, namely radiographers who work in the UK National Health Service Breast Screening Programme. All 134 radiographers in the first wave of the programme were sent a postal questionnaire to determine how stressed they felt at work, how satisfied they were with the job, and what were the principal causes of stress and dissatisfaction. A total of 103 were returned, a response rate of 77 %. The results showed that 30 % reported high levels of stress, which is more than in most other professions, and that only 17% described themselves as ‘very satisfied’ with their jobs. The most important predictors of stress were problems of communication (mainly knowing what to tell the client) and conflicts between home and work. The most important predictor of dissatisfaction was role ambiguity. Ways of reducing stress and increasing satisfaction must be found if radiographers are to remain healthy and are to continue to work for the programme.     

Performance of Robust RA Estimator for Bidimensional Autoregressive Models

The additive AR-2D model has been successfully related to the modeling of satelital images both optic and of radar of synthetic opening. Having in mind the errors that are produced in the process of captation and quantification of the image, an interesting subject, is the robust estimation of the parameters in this model. Besides the robust methods in image models are also applied in some important image processing situations such as segmentation by texture and image restoration in the presence of outliers. This paper is concerned with the development and performance of the robust RA estimator proposed by Ojeda (1998) for the estimation of parameters in contaminated AR-2D models. Here, we implement this estimator and we show by simulation study that it has a better performance than the classic least square estimator and the robust M and GM estimators in an additive outlier contaminated image model.     

和谐社会实践中档案职业的角色意识

在构建社会主义和谐社会的进程中，社会对档案工作提出了新的要求。档案职业的角色意识，包括维护档案的历史真实性的使命感、责任感的意识，档案资政惠民服务功能的意识，勇于创新和开拓精神的意识。这是社会对档案职业的角色期望，是社会对档案职业这个岗位所要求的职责所在，也是档案职业者站在角色位置上要表现的符合角色行为的神圣使命。

审计在基金会治理中能够有效发挥作用吗?

本文以2005年至2009年中国全国基金会为样本,研究基金会捐赠收入与外部审计师选择之间的关系,即在中国慈善市场上,外部监督机制之一的外部审计是否具有治理效应及治理职能如何有效实现。实证结果表明:当基金会选择百强事务所审计时,能够有效实现审计的治理职能,吸引更多的捐赠者进行捐赠;当基金会选择民政部中标事务所审计时,不能有效实现审计的治理职能,从而不能显著增加捐赠收入。上述结论在一定程度上验证了在慈善市场中,外部审计具有治理效应,其有效治理效应依赖于高质量的审计。     

The reform of the welfare services in Norway: one office – one way of thinking?

This paper discusses the professional role of social workers in the new Norwegian Nav system. The Nav reform merged the state social insurance office, the state employment office and components of municipal social services. The aim is to include clients in the work force by making the services more holistic and efficient. The paper presents a discussion of the introduction of the ‘Nav reform’, drawing on a qualitative multi-method study. The material sheds light on a social worker's role under pressure to work in a more standardised and ‘simplified’ way. Social workers at the Nav offices must adjust to expectations that require a general, basic and common competence for all employees, as one type of comprehensive, but simplified and non-specialised, approach. The study describes the dilemma of how to combine one-stop service and specialist principles. The paper attempts to criticise ‘the flexible system’ related to Whole of Government perspectives and one-stop service principles as a generalist ‘light’ approach, as opposed to the generalist approach in social work. The findings provide a basis for raising questions about the development of the social worker's role in light of the post-New Public Management (NPM) reforms and the potential threat to the professional basis of social work.     

The AGENCY Computer Simulation Model

AGENCY is a computer simulation model developed to emulate service delivery in a mental health center, but broadly applicable to most human service delivery organizations. Definition of the service providing agency is input to the program from a separate data file, so the program is extremely flexible and general. Initial validation results are positive. The program is written in SIMULA to run on a DEC-10.     

A Public Transportation Decision‐Making Model within a Metropolitan Area

Understanding the decision‐making factors associated with public transportation is essential in strategic development of public transportation to improve acceptance and utilization of mass transit systems. This research analyzes factors affecting attitudes toward public transportation and the choice of transportation mode by investigating the public transportation decision‐making process of working professionals using a survey methodology. The objectives of this research are to model the transportation decision‐making process of public transportation users in a metropolitan area and to determine key factors that affect the public transportation choices made by potential public transportation users. This study contributes to the literature by developing and testing an integrated theoretical framework for modeling an individual's public transportation decision‐making process using four independent variables: Perceived Public Transportation Security, Knowledge, Price, and Convenience. We develop the proposed theoretical framework based upon the extant literature and tested it using partial least squares structural equation modeling (PLS‐SEM). Based on the Theory of Reasoned Action, the Theory of Planned Behavior, and utility theory, we develop the factors and refine associated items using confirmatory factor analysis.
