数字化图书馆检索体系的层次结构模型

提出数字化图书馆检索体系的4层结构(界面层、传输层、中间层和资源层)。数字化图书馆的检索过程可以描述为这4个层次间的信息流动。中间层连接了界面层和资源层，是数字化图书馆检索体系的核心，它决定了数字化图书馆的基本特点，是数字化图书馆检索体系研究的主要内容。     

The myth of the biotech revolution: An assessment of technological, clinical and organisational change

This paper argues that despite being widely promoted by academics and consultants, the empirical evidence does not support the existence of a biotech revolution. Nor does the data support the widely held expectations that biotechnology is having a revolutionary impact on healthcare or economic development. The revolutionary model is therefore a misleading basis for policy making as it over-estimates the speed and extent of any changes in productivity or the quality of therapeutics. Instead, the evidence suggests biotechnology is following a well-established incremental pattern of technological change and ‘creative accumulation’ that builds upon, rather than disrupts, previous drug development heuristics.     

Popular culture and moral panics about ‘children at risk’: revisiting the sexualisation-of-young-girls debate

In an attempt to resist moral panics over children's media consumption, and especially girls' consumption of hyper-sexualised popular media, this paper aims to offer a more positive account of popular culture and young children's, especially girls', engagement with it. By adopting a historical approach to modern childhood and the moral panics associated with it, I argue that the consumption of entertainment media and popular culture is a leisure activity which, rather than facilitating or reinforcing female subordination and youth vulnerability, can be seen as a possible source of knowledge about sexuality, about the self and the social world. I draw on findings from qualitative research conducted in Athens with young schoolgirls aged 10–12 years about their favourite popular icons in order to examine the variety of their engagements with, readings and practices of popular culture. Their discursive accounts reveal the intricate ways in which pre-teenage girls make sense of fandom and stardom, discuss taste, fashion and body aesthetics, and construct notions of attractiveness and ethical selfhood.     

Modelling age and secular differences in fitness between basketball players

Concerns about the value of physical testing and apparently declining test performance in junior basketball players prompted this retrospective study of trends in anthropometric and fitness test scores related to recruitment age and recruitment year. The participants were 1011 females and 1087 males entering Basketball Australia's State and National programmes (1862 and 236 players, respectively). Players were tested on 2.6 +/- 2.0 (mean +/- s) occasions over 0.8 +/- 1.0 year. Test scores were adjusted to recruitment age (14-19 years) and recruitment year (1996-2003) using mixed modelling. Effects were estimated by log transformation and expressed as standardized (Cohen) differences in means. National players scored more favourably than State players on all tests, with the differences being generally small (standardized differences, 0.2-0.6) or moderate (0.6-1.2). On all tests, males scored more favourably than females, with large standardized differences (>1.2). Athletes entering at age 16 performed at least moderately better than athletes entering at age 14 on most tests (standardized differences, 0.7-2.1), but test scores often plateaued or began to deteriorate at around 17 years. Some fitness scores deteriorated over the 8-year period, most notably a moderate increase in sprint time and moderate (National male) to large (National female) declines in shuttle run performance. Variation in test scores between National players was generally less than that between State players (ratio of standard deviations, 0.83-1.18). More favourable means and lower variability in athletes of a higher standard highlight the potential utility of these tests in junior basketball programmes, although secular declines should be a major concern of Australian basketball coaches.     

Government Policy and School Development

The last 10 or 15 years of this century have been a time of great challenge as well as considerable excitement for educational systems around the world. Governments everywhere have been embarking on substantial programmes of reform in an attempt to develop more effective school systems and raise levels of student learning and achievement. We see in these policy initiatives an unfortunate paradox that inhibits them from realising their aspirations. The community of educational change researchers and practitioners has finally begun to learn something about how ongoing improvement can be fostered and sustained in schools. However, government policy on education has not taken adequate account of this knowledge about school development, with the result that an enormous potential source of synergy has been lost and student learning continues to lag behind its potential. Our argument in this article is that as a consequence of this gap government efforts to improve schooling are less effective than they might be and that many school improvement efforts have to swim against the current of government regulation. Following our analysis of this central irony in educational policy, we go on to outline an approach that would be more likely to help governments achieve their educational objectives by building policy initiatives more explicitly on the knowledge base of school development.     

友善员工更富于创造力

It may seem more professional to stay impersonal(非个人的)at work, but in fact friendlier employees are more productive.A comparison of the American work ethic(道德规范)toapproaches in other countries shows that keeping an emotional distance may not be the most effective way to get the job done.     

The relationship between quality of the present level of academic achievement and functional performance statement and student learning

The present level of academic achievement and functional performance (PLAAFP) is an essential component of the individualised educational program (IEP) process because it identifies student strengths and areas for growth. However, there is minimal research that examines components of an IEP and student outcomes. The current study examined the relationship between PLAAFP quality and student achievement, and between training and ongoing professional development and quality of the PLAAFP. The data were obtained from 211 special education teachers in one state. Results suggested that ongoing professional development predicted the quality of the PLAAFP statement, accounted for a large amount of the variance (r² = 0.14) in the PLAAFP quality score, and was a stronger predictor than participating in a single training. Additionally, PLAAFP quality predicted winter achievement scores beyond the school district, fall achievement scores and teacher variables, and accounted for significant and moderate amount of unique variance for reading (r² = 0.05) and math (r² = 0.07). Implications for research and practice are included.     

The path of least resistance: a voice‐relational analysis of disabled students’ experiences of discrimination in English universities

Recent legislation means that it is now illegal to treat a student, for reasons relating to a disability, less favourably than a non‐disabled student unless this is justified to maintain academic standards. However, recent research has identified numerous barriers faced by students with disabilities when they attempt to access the higher education curriculum. This study uses a methodology combining life‐story approaches with a voice‐relational analysis and aims to explore in more detail these barriers by listening to first person accounts from university students with a disability. The students’ narratives suggest that disabled students have to work considerably harder than non‐disabled students to overcome a wide range of physical, attitudinal, social, cultural and political barriers. Students appear to take the path of least resistance by choosing routes where the barriers are least great and it is argued that in this way they are being discriminated against. The research shows that voice‐relational methodology is excellent at producing a thorough account of the phenomenological world of these students without neglecting a materialist and cultural analysis of their environment. These insider perspectives are then used to suggest possible improvements to policy and practice in higher education.
