西宁市某中学学生艾滋病知识、态度、行为的调查研究

目的了解西宁市某中学学生艾滋病知识、态度、行为现状,为更好地开展中学生艾滋病健康教育工作提供依据。方法采取多阶段随机整群抽样方法,对西宁市某中学275名初、高中学生开展艾滋病防治知识、态度、行为问卷调查。结果被调查学生艾滋病知识总知晓率仅为41.09%,不同年级和性别学生对艾滋病基本知识的认知不同,获取艾滋病防治知识的途经和渠道从高到低依次是电视/广播/网络、报刊/杂志、同学/朋友、家庭成员、老师、学校等;仅有37.50%的中学生不歧视艾滋病病毒感染者和病人,不同年级、不同性别学生对待艾滋病的态度和行为不同。结论西宁市某中学学生对艾滋病基本知识掌握不够全面,不能正确对待艾滋病病人或感染者,存在着明显的歧视倾向。     

零污染、零感染、零废弃物排放变废为宝的人类如厕解决方案

冲水厕所是都市和城镇化的标志,也是近代人类文明的象征。由于冲水厕所建设需要投资庞大的建筑管道网络配套系统、管道维护及技术复杂昂贵的高耗能污水处理运营系统,冲水厕所的数量和位置受到限制,世界上只有在比较发达地区得到普及。2008年全世界有25.78亿人没有卫生厕所。在中国,25394.2万户农村人口中只有1578.6万(6.2%)的农户拥有完整下水道冲水厕所。一些农村城镇仍然使用旱厕,卫生条件差,夏天蚊蛆四窜、苍蝇乱飞、臭气熏天。即便如此,相当多的农村城镇学校仍然由于蹲

Co-evolution of physical and social technologies in clinical practice: The case of HIV treatments

In this paper, we investigate the interplay of clinical knowledge and technological capabilities in the recent development of HIV/AIDS treatments and offer qualitative and quantitative evidence from the empirical setting of Italian practice. The study contributes to the literature on the co-evolution of physical and social technologies in medical innovation by showing how professional guidelines, systematic evaluative research and local coordination mechanisms contribute actively to the resolution of the uncertainty that surrounds technological advances, while leaving room for largely discretional therapeutic choices. The resulting variety in implementation strategies improves health outcomes, but may reduce productive efficiency.

Uses of information and communication technologies in HIV self-management: A systematic review of global literature

Information and Communication Technology (ICT) has been applied increasingly in supporting human immunodeficiency virus (HIV) prevention and treatment. The technological advances have extended to the field of HIV self-management. The objectives of this paper are to examine the design and use of ICTs in HIV self-management programs, to identify the knowledge gaps in existing practice, and to provide recommendations for future research and program development. A systematic review was conducted to search all English literature published prior to August 2016 in six electronic databases. The inclusion criteria also included either quantitative or qualitative assessments of HIV self-management programs that utilized at least one ICT platform in the program protocol. The search identified six studies conducted in Australia and the United States. The studies were diverse in sample size and enrollment criteria of study population. The major functionalities of ICT platforms (mobile phones and websites) included delivering information modules, sending medication reminders, supporting self-monitoring for medical adherence and risk behavior reduction, enhancing communication among participants, and providing easy access to HIV self-management information. The major challenges faced by self-management programs utilizing ICTs were lack of interaction and concern of privacy. The HIV self-management programs that employed ICT platforms were limited in number and geographic coverage. Most of the programs were also tested at an initial stage with small size samples and minimum technical innovation. The lack of explicit guiding theories and models on information behavior or technology use was observed in all studies. Use of ICTs in HIV self-management interventions is an emerging field. Future research would benefit from paying more attention to technical innovation and interactive features in applying ICT platform in self-management programs. The ICTs platforms, with increasing innovation in connecting people and places, can serve as a powerful tool to reduce the disparities in health care and health promotion. Future research is also needed to explore the feasibility of applying ICT platforms in self-management programs that serving populations from diverse socioeconomic background and in resource-poor settings.     

Surveillance,Privacy and the Ethics of Vehicle Safety Communication Technologies

Recent advances in wireless technologies have led to the development of intelligent, in-vehicle safety applications designed to share information about the actions of nearby vehicles, potential road hazards, and ultimately predict dangerous scenarios or imminent collisions. These vehicle safety communication (VSC) technologies rely on the creation of autonomous, self-organizing, wireless communication networks connecting vehicles with roadside infrastructure and with each other. As the technical standards and communication protocols for VSC technologies are still being developed, certain ethical implications of these new information technologies emerge: Coupled with the predicted safety benefits of VSC applications is a potential rise in the ability to surveil a driver engaging in her everyday activities on the public roads. This paper will explore how the introduction of VSC technologies might disrupt the “contextual integrity” of personal information flows in the context of highway travel and threaten one’s “privacy in public.” Since VSC technologies and their related protocols and standards are still in the developmental stage, the paper will conclude by revealing how close attention to the ethical implications of the remaining design decisions can inform and guide designers of VSC technologies to create innovate safety applications that increase public safety, but without compromising the value of one’s privacy in public. This work was supported by the National Science Foundation PORTIA Grant No. CNS-0331542, and could not have been completed without the valuable guidance of Prof. Helen Nissenbaum (New York University) and Prof. Dan Boneh (Stanford University). I am grateful to many other colleagues who generously contributed to this work with excellent comments and suggestions, including Emily Clark and Steve Tengler at the VSCC, and Sam Howard-Spink, Joseph Reagle and Tim Weber at New York University. Drafts were further sharpened through opportunities to present at colloquia and conferences sponsored by New York University’s Department of Culture & Communication, the American Association for the Advancement of Science, the Society for Philosophy and Technology, and Computer Ethics: Philosophical Enquiry.     

The Victorian Information Society: Surveillance, Bureaucracy, and Public Librarianship in 19th-Century Britain

Contrary to the "retro" image often awarded them, and despite their continuing enthusiasm and responsibility for the organization of printed materials, librarians are upbeat about the prospects of an information society driven primarily by electronic technologies, but in which libraries can play an important part. Public librarians detect a natural correlation between the historic democratic mission of their institution and the increased accessibility made possible by digitalized sources. The library community's acceptance of the information society idea as a "given" social phenomenon supports discourses that play down historical continuities and herald the dawn of a new age. Such discourses ignore or reject historical evidence that points to the existence of past information societies, revolutions, and infrastructures defined, in part, by the operation of indirect surveillance, constituted by the bureaucratic information systems of modernity. Victorian Britain serves as a good example of an early information society, to which public libraries, themselves micro-information societies, contributed significantly. The role played by public librarians in the Victorian information society, illustrated in this article by evidence drawn from the contemporary library press, is seen in their preoccupation with the surveillance and ordering of knowledge; their adoption for library operations of the businesslike, bureaucratic procedures described recently by business historians; and their panoptic tracking of users and their activities.
