The effect of number of siblings and birth order on educational attainment: Empirical Evidence from Chinese General Social Survey

Data from China demonstrate that the effect of the number of siblings on education is restricted by many factors, such as children’s gender, urban or rural household registration, whether there is only one child, the birth order of children within the family, and parents’ status. Chinese families have significant preferences for the eldest son and the youngest son. Moreover, research based on the natural experiment and instrumental variable approach suggests that market-oriented reform of education has increased the cost of family education expenditures since China’s reform and opening up, which further aggravates the negative impact on education of having many siblings in an urban setting.

道家与道教人生观及人生实践之比较

道教的基本理论直接来源于道家思想,道家与道教有同而又有所不同,道家的自然无为、重生轻物、与世无争的人生观与道教的善生保真、追求长生的人生观具有惊人的相似之处。落实到具体的人生实践上,便是道家游方之外,因愤世嫉俗而远离政治,着重于追求内心自由、返朴归真,以一种出世姿态遁隐山林。道教从建立之初就积极地干预政治、游方之内。用实修的方法,追求长生不老、羽化登仙,努力地有所作为。道家的出世与道教积极入世的人生实践又有极大的不同之处。     

Developing the evidence base for UK film strategy: the research process at the UK Film Council

The UK Film Council established a Research and Statistics Unit in order to gather data relating to film to inform the development of UK Film Council strategy and to provide an information service to the industry, government, the arts and cultural sector and the wider research community. The Research and Statistics Unit draws data from both official and unofficial sources and commissions its own special-purpose studies to gather information relevant to the strategic objectives of the Council. Key tasks are the measurement of the size of the market for film and the various elements of the film value chain, the performance of films supported by the UK Film Council and the performance of UK films in general. Special-purpose research projects currently include a detailed survey of the film production workforce, a study of the economic impact of the UK screen industries and studies of the social impact of local cinemas and the experience of Black- and Minority-led film production companies. A range of industry and official partners are collaborating in these studies. The Research and Statistics Unit also provides statistical and policy analysis relating to the wider policy environment of UK film, including issues such as the future of film tax incentives. This analysis has been developed within the HM Treasury ‘Green Book’ framework with particular reference to understanding market failure in relation to film. Central to the market failure argument is the cultural value of film in both its qualitative and its quantitative aspects. UK Film Council research is placed in the context of the literature on hedonic pricing and contingent valuation. The industrial challenges of increasing cultural value are discussed. Finally, consideration is given to the potential of film to contribute directly to ‘public value’.
