投影机的接口

一般用户使用投影机,其实就是对输入输出接口的操作。投影机的接口按照用途可以分成音频接口、视频接口、控制接口和综合接口四种。USB连线投影,无线网络投影等是当前的热门技术。投影机的接口发展呈现出数字化、高速化、集成化、轻便化等特征。     

基于.NET Web Service的动态接口设计与实现

由于智能手机的普及和社会信息化的不断发展,人们希望能通过手机或者平板的APP对原有B/S架构的信息化系统进行操作,因此这些系统就需要为移动端的APP提供访问系统内部业务逻辑的接口,而如何为APP快速高效地提供这些接口一直是个难题。如果服务器只向外界暴露一个接口,而外部应用只需通过调用该接口就可以完成服务器中所有的业务逻辑,则会大大降低接口的开发时间和成本。该类接口被称为“动态接口”,设计并实现了基于Web Service的动态接口,以提高接口开发效率。

关于心理生活基本性质和内涵的理解

人的心理生活是人的现实生活的重要构成。理解心理生活的性质和内涵，必须考虑如下几个方面。一是人性与心理生活。心理生活是人所拥有和创造的生活。二是自我与心理生活。这涉及到人格与自我，主我与客我，大我与小我。三是认知与心理生活。这包括认知的性质：对象的认知和生存的认知。四是意向与心理生活。意向决定了心理生活的一体性和自主性。五是观念与心理生活。人的心理生活是对意义的追求，意义的基本心理单元就是观念。六是体验与心理生活。心理体验是指感受、感悟、觉解、觉悟、思想、思念、体察、体会等。七是超越与心理生活。人的心理生活有价值的评判、有追求的目标和有超越的品性。八是创造与心理生活。人的心理有双重的创造功能，包括对外部生活世界和对自身心理行为的建构。     

从文明无知、文明冲突到文明交往、文明和谐--对学术界三种文明观的基本述评

文明是决定和影响人类活动的长期的基本因素。冷战结束后，特别是随着“文明冲突论”的提出，各种文明观的讨论逐渐演化成文明学的各种派系。当前主要有三种文明观：文明冲突论、文明对话论、文明交往论。在处理国与国关系的实践中应承认并维护文明的多样性。文明发展的趋势是文明和谐和文明相处。人类真正的危险在于各个民族、国家间文明的互不相融，以及由此导致的误解、紧张、冲突乃至战争。世界的持久和平与持续发展有赖于人与人之间、民族与民族之间、国家与国家之间文明的对话、沟通和理解，有赖于文明间的和谐，共同发展。     

中西方美学比较

中西方美学分别产生于春秋战国与古希腊罗马时期。先秦美学强调人与人之间的协调性、艺术对情感的表现性及善与美的教化性；古希腊美学强调人与自然的和谐性、艺术对现实的再现性及真与美的功利性。中国的艺术哲学产生于魏晋时期，《文心雕龙》完成了中国古代美学体系的建构。西方直到文艺复兴时代随着人性复苏、艺术哲学的发展，康德与黑格尔的美学体系才得以诞生。中西方美学体系形成之展开方式虽有不同，但基本规律一致。     

The Trend Towards Materials in Science and Technology Education

The teaching of science and technology in the final year of high school is examined in a new curriculum developed for the education system in Victoria, Australia. The traditional areas of Physics and Chemistry together with a technology related subject, Materials and Technology, are investigated The major curriculum link amongst these studies was the area of materials. In Chemistry this involved the nature of materials, the chemical basis for the production of metals and polymers, and the social consequences of waste disposal. Within Physics, the major involvement was the investigation of the structure and physical properties of materials through theory and practical investigation. The selection of materials, production of components and their testing were the major area involved with Materials and Technology. Although the area of materials related all three subjects enrollments were comparatively high for Physics and Chemistry but Materials and Technology had less than one tenth as much enrollment. Similarly, school providers were significantly lower for materials and technology. Materials and Technology is still considered a vocational subject compared with the science oriented subjects. When gender enrollments were considered, Chemistry had a similar number of females and males, Physics had twice as many males as females, and Materials and Technology had twice as many males as females. This appears to be a consequence of typical gender roles.

劳伦斯与非理性主义

以叔本华、尼采、弗洛伊德为代表的非理性主义是劳伦斯小说创作的思想基础。受叔本华影响,劳伦斯把生存意志作为人物行动的基本动力,这主要表现为向性力和精神占有欲。受尼采影响,劳伦斯赞美躯体,重视生命的内在能量和自我超越性,并与基督教决裂,成为西方基督教道德观的激烈批判者。劳伦斯在性与无意识这两个领域,对弗洛伊德精神分析理论有接受,也有超越。弗洛伊德与劳伦斯都把性、无意识与文明对立起来,但弗洛伊德进行的是否定性研究,强调对其疏导和控制,劳伦斯则认为性与无意识是原初的创造性力量,是生活的源泉,是对抗人之社会化和理性化的正面力量。非理性主义丰富和深化了劳伦斯对现代人心理世界的理解,加强了他的小说的社会批判力量。

学科和课程分化与综合的辩证法

科学和学科是课程的基础,科学和学科内容的发展趋势必然影响课程教学内容的发展走势。科学、学科和课程的分化与综合是辩证的。分化是综合的基础,综合是分化的结果。没有分化就没有综合,只是混沌。在分化基础上的综合和在综合基础上的分化既是近现代科学、学科和课程发展的基本趋势和规律,也应该是未来科学发展、学科建设和课程改革的基本依据。     

A Systematic Review of Barriers and Facilitators of Disability Disclosure and Accommodations for Youth in Post-Secondary Education

This review critically appraised the literature on disability disclosure and accommodations for youth with disabilities in post-secondary education (PSE). Systematic searches of 8 databases identified 36 studies meeting our inclusion criteria. These studies were analysed with respect to the characteristics of the participants, methodology, results of the studies and quality of evidence. Five thousand, one hundred and seventy four participants (mean age 26.4) were represented across six countries. Barriers to disability disclosure and requests for accommodations in PSE included stigma, discrimination, lack of knowledge of supports and how to access them, type of course and instructor, coping styles, and nature of the disability. Facilitators included supports and resources, coping and self-advocacy skills, mentorship, and realising the benefits of disclosure. Factors affecting the process and timing of disability disclosure in PSE included the type of disability, and mode of disclosure. There was a lack of consensus on the timing of disclosure.     

A Subtle Tyranny: Rediscovering the Purpose of the Liberal Arts

Discord in the academy currently manifests in divisions over political correctness, the content of the canon and the defects of modernity. As scholarly and intellectual matters these concerns arise exclusively from the domain of the liberal arts. At their core, these controversies arguably develop from deep epistemic roots reflecting fundamental differences concerning the nature, purpose and value of the liberal arts. At issue is the integrity of the liberal arts and understanding the nature, purpose and value of these fields depends upon appreciating the distinction between professional, theoretical, and moral studies. One can begin to understand these distinctions by considering the contrast in ordinary language between knowledge and wisdom. For it is arguable that while the notion of wisdom is presumably irrelevant to production or dissemination of knowledge in all other disciplines, it is demonstrably central to the purpose and value of both research and teaching in each and every liberal art. If this can be shown then it is possible to understand why emphasis on expertise and professionalism, on knowledge for its own sake undermines commitment to common purposes and concerns. By institutionalizing new patterns of behavior, stress on professionalism changes the nature and conception of liberal arts scholarship in ways that produce deep confusions about meaning and value in these fields. The object of this article is to show that unlike other disciplines the liberal arts depend upon shared purposes and concerns such that participation of in a common moral discourse is essential to the integrity and worth of each field.
