中国国家图书馆中文名称规范工作的思考 总被引:1,自引:0,他引:1
我国中文名称规范工作处于发展起步阶段,在实践中面临诸多问题.数据整合过程中编目业务流程内外如何协调和制作标准如何统一,以及规范控制中是否所有书目数据中的名称标目都要做规范数据、是否所有名称都要并尽量区分、规范记录是否要面面俱到等等,都是需要思考与解决的问题.当前阶段的规范工作应该避免单纯的理论化,需借鉴国外经验,重视可行性. 相似文献

This study investigated whether ischemic preconditioning (IPC) in a trained population affected repeated sprint performance. A secondary aim was to assess responses according to gender. Sixteen (nine females and seven males) well trained team sport athletes took part in a randomised crossover study design. Participants underwent an IPC and placebo treatment involving three periods of 5 min occlusion applied unilaterally (3 × 5 min occlusion to each leg) at either 220 mmHg or 50 mmHg. Each period of occlusion was followed by 5 min reperfusion. Following treatment 5 × 6 s maximal effort sprints were undertaken on a cycle ergometer against 7.5% body mass, each interspersed by 24 s recovery. Measured parameters included peak power, total power, percentage decrement, post-exercise blood lactate and ratings of perceived exertion. Nor within subject main effect for IPC was observed, neither was there an interaction effect with gender. Effect sizes were trivial (ES < 0.2) with the exception of a moderate (ES < 1.2) change in post-exercise blood lactate in the female cohort (1.6 ± 0.4 mmol?1 lower following IPC). Results suggest no benefit to team sport players in utilising IPC as a means of enhancing repeated sprint performance. A lower blood lactate response in female participants following IPC may suggest improved blood flow through vasodilation. 相似文献

“破窗理论”是社会治安治理的一个重要理论。过去三十余年,“破窗理论”的提出在警察学界和犯罪学界引发了广泛而深入的学术讨论。威尔逊和凯林在彼得曼和津巴多研究的基础之上提出了“破窗理论”,发现了无序行为与犯罪行为二者间的内在联系。无序行为与犯罪行为是否存在直接关联?这一问题引发了学术界赞成派和反对派的深入讨论。这些问题的讨论,深化了人们对无序行为与犯罪行为的理解,对社会治安的改善有着积极的促进作用。 相似文献

eCommerce, Brexit, new safety and security concerns are only a few examples of the challenges that government organisations, in particular customs administrations, face today when controlling goods crossing borders. To deal with the enormous volumes of trade customs administrations rely more and more on information technology (IT) and risk assessment, and are starting to explore the possibilities that data analytics (DA) can offer to support their supervision tasks. Driven by customs as our empirical domain, we explore the use of DA to support the supervision role of government. Although data analytics is considered to be a technological breakthrough, there is so far only a limited understanding of how governments can translate this potential into actual value and what are barriers and trade-offs that need to be overcome to lead to value realisation. The main question that we explore in this paper is: How to identify the value of DA in a government supervision context, and what are barriers and trade-offs to be considered and overcome in order to realise this value? Building on leading models from the information system (IS) literature, and by using case studies from the customs domain, we developed the Value of Data Analytics in Government Supervision (VDAGS) framework. The framework can help managers and policy-makers to gain a better understanding of the benefits and trade-offs of using DA when developing DA strategies or when embarking on new DA projects. Future research can examine the applicability of the VDAGS framework in other domains of government supervision. 相似文献

School bullying attracts significant research and resources globally, yet critical questions are being raised about the long-term impact of these efforts. There is a disconnect between young people's perspectives and the long-established psychology-based technical definitions of school bullying dominating practice and policy in Australia. This dominant paradigm has recently been described as the first paradigm of school bullying. In contrast, this paper explores the potential for reorienting school bullying research towards the concerns of young people and away from adult-derived technical definitions. Borrowing from paradigm two, which emphasises the social, cultural and philosophical (among others) elements of school bullying, in this paper, I approach bullying under the broad banner of ‘social violence’. This approach addresses some of the inherent limitations of the first paradigm to conceptualise social and cultural dynamics. I argue that a ‘social violence’ approach reveals that the exclusionary effects of the social phenomenon of youth continue to be overlooked. Furthermore, the term ‘violence’ in bullying research could benefit from integrating contemporary sociological insights on this phenomenon. This paper draws on qualitative insights from a small group of young people in secondary schooling in South Australia gained through prolonged listening to peer conversations in a series of focus groups. In addition, 1:1 interviews were conducted pre and post the focus group series. I argue that these participants' insights reveal the exclusionary effects of youth and the employment of bullying to trivialise young people's experiences and concern for harm. There is a need to reprioritise young people's knowledge in school bullying research and the exclusionary effects of youth alongside other social forces. 相似文献

The process of comprehending a problem, strategically developing a solution and translating the solution into an algorithm
is arguably the single most important series of skills acquired during the education of an undergraduate computer science
or information technology major. With this in mind, much care should be taken when choosing a programming language to deploy
in the first University programming course. BLAKE, Beginners Language for Acquiring Key programming Essentials, is designed
specifically for use in a Programming I class. BLAKE aids in enforcing fundamental object-oriented practices while simultaneously
facilitating the transition to subsequent programming languages. BLAKE’s major features include; consistent parameter passing,
single inheritance, non-redundant control structures, a simple development environment, and hardware independent data types.
The syntax remains relatively small while still facilitating a straightforward transition to industry standard programming
languages. 相似文献

Separate Catholic schooling in Britain has historically been a key mechanism for the religious socialisation of children within the denomination and for the transmission of communal identity and heritage. Catholic schools currently comprise around a tenth of all state schools in England and nearly all ‘denominational’ schools in Scotland. This study analyses Catholics’ attitudes towards publicly funded faith schools for different religious groups using a nationally representative survey of adult Catholics in Britain. It assesses the impact of social characteristics, religious behaving and believing, and moral attitudes. Catholics’ religious orthodoxy is consistently related to support for state-funding of faith schools, irrespective of the religious group in question, providing some support for the ‘solidarity of the religious’ perspective. The effects for moral attitudes are less consistent, with socially conservative views associated with support for faith schools for Catholics and Anglicans, but associated with opposition to faith schools in general and for non-Christian religions. 相似文献

This paper argues that methods used for the classification and measurement of online education are not neutral and objective, but involved in the creation of the educational realities they claim to measure. In particular, the paper draws on material semiotics to examine cluster analysis as a ‘performative device’ that, to a significant extent, creates the educational entities it claims to objectively represent through the emerging body of knowledge of Learning Analytics (LA). It also offers a more critical and political reading of the algorithmic assemblages of LA, of which cluster analysis is a part. Our argument is that if we want to understand how algorithmic processes and techniques like cluster analysis function as performative devices, then we need methodological sensibilities that consider critically both their political dimensions and their technical-mathematical mechanisms. The implications for critical research in educational technology are discussed. 相似文献

We study the input-to-state stability (ISS) of switched nonlinear input delay systems under asynchronous switching. Our results apply to cases where some subsystems of the switched systems are not necessarily stable under the influence of input delay. By making a compromise among the matched-stable period, the matched-unstable period, and the unmatched period and allowing the increase of the Lyapunov–Krasovskii functional (LKF) on all the switching times, the extended stability criteria for switched delay systems in generally nonlinear setting are derived first. Then, we focus on switched nonlinear input delay systems where the presence of the input delay leads to the instability of some subsystems of it. By explicitly constructing input-to-state stable LKF, the sufficient conditions for ISS of switched nonlinear input delay systems under asynchronous switching are presented. Finally, two examples are given to illustrate the effectiveness of the proposed theory. 相似文献
