合并升本院校实行矩阵管理的构想     

景丽芳  刘春 《福建工程学院学报》2005,3(5):431-434

针对合并、“升本”院校面临的管理挑战，提出了矩阵管理的构想，认为合并、“升本”院校可根据实际分别采用简单型和混合型两种矩阵管理模式，以缩短“磨合期”和“适应发展期”，并强调了实行矩阵管理应注意的几点问题。  相似文献   

城市居民消费结构变动的因子分析     

纪荣芳  娄本平 《德州学院学报》2006,22(6):80-82,89

在居民消费结构研究中,应用最广泛的是恩格尔系数和线性支出系统,但在进行消费结构变动分析时,因指标较多且各指标的变化趋势不尽相同,很难看出居民消费在某一方面的变动趋势.多元统计分析中的因子分析法正是解决这一问题的有力工具,文中利用因子分析法和DPS数据处理系统,对泰安城市居民消费结构的变动情况进行了分析.  相似文献

Consumer health information seeking in social media: a literature review          下载免费PDF全文

Yuehua Zhao  Jin Zhang 《Health information and libraries journal》2017,34(4):268-283

Objective

The objective of this literature review was to summarise current research regarding how consumers seek health‐related information from social media. Primarily, we hope to reveal characteristics of existing studies investigating the health topics that consumers have discussed in social media, ascertaining the roles social media have played in consumers’ information‐seeking processes and discussing the potential benefits and concerns of accessing consumer health information in social media.

Methods

The Web of Science Core Collection database was searched for existing literature on consumer health information seeking in social media. The search returned 214 articles, of which 21 met the eligibility criteria following review of full‐text documents.

Conclusion

Between 2011 and 2016, twenty‐one studies published explored various topics related to consumer information seeking in social media. These ranged from online discussions on specific diseases (e.g. diabetes) to public health concerns (e.g. pesticide residues). Consumers’ information needs vary depending on the health issues of interest. Benefits of health seeking on social media, in addition to filling a need for health information, include the social and emotional support health consumers gain from peer‐to‐peer interactions. These benefits, however, are tempered by concerns of information quality and authority and lead to decreased consumer engagement.  相似文献

This year's virtual issue (the 6th in the series) has been published to coincide with the European Association for Health Information and Libraries’ (EAHIL) 2015 workshop (10–12 June, Edinburgh): Research‐Minded: Understanding, Supporting, Conducting Research. This event is being run in collaboration with the International Conference of Animal Health Information Specialists and the International Clinical Librarian Conference. Although research has always been a central part of any librarian's role, until recently health librarians and library users and funding bodies assumed that librarians were ‘midwives’ – there to assist students, clinicians, academics and managers set up and carry out their research. The notion of the librarian as a professional with a research agenda, who understands research methods, submits research grants, and publishes, is a relatively new perspective. If librarians are to take an evidence‐based approach to their profession they need to acquire research skills. This is the rationale for the 2015 EAHIL workshop. To support the workshop, this virtual issue contains six original articles published in Health Information and Libraries Journal over the last 2 years that demonstrate the range of research activities carried out by health librarians, as well as a review article and articles from each of the three feature columns. All articles included in this virtual issue are available free online.  相似文献   

The use of standardized residuals to derive value‐added measures of school performance     

Ian Schagen 《Educational studies》2006,32(2):119-132

Measures of school performance based on pupil attainment are becoming more sophisticated, with DfES piloting ‘contextualized value‐added’ measures. However, most such measures are based on simple sums of residuals about ‘expected’ values, but it is clear from national data that distributions of performance are not symmetrical and of constant variance. A method is explored which takes account of the exact shape of the performance distribution to produce ‘standardized residuals’ which can be aggregated to the school level and give consistent measures on a fixed metric. Examples are given based on national data.  相似文献
