Responding to Big Data in the Art Education Classroom: Affordances and Problematics          下载免费PDF全文

Paul Duncum 《The International Journal of Art & Design Education》2018,37(2):325-332

The article raises questions about the use in art education classrooms of social networking sites like Facebook and image sharing sites like YouTube that rely upon the ability of Big Data to aggregate large amounts of data, including data on students. The article also offers suggestions for the responsible use of these sites. Many youth are using these sites as creative platforms and, taking their lead, the author describes his own use of YouTube as a creative tool in his pre‐service classroom. The author argues that most art educational literature that relies upon Big Data sites consider only the affordances and not the problematics involved, specifically issues of privacy and having youth effectively working as unpaid labour for global corporations.  相似文献   

Differences in mobile health app use: A source of new digital inequalities?     

Nadine Bol  Natali Helberger  Julia C. M. Weert 《The Information Society》2018,34(3):183-193

This article provides a more differentiated understanding of mobile health consumers, and considers whether health app use may contribute to new digital inequalities. It focuses on factors associated with mobile health app use, and identifies which factors explain the use of different types of health apps. Data from a large representative sample of the Dutch population (N = 1,079) show that mobile health app users were generally younger, higher educated, and had higher levels of e-health literacy skills than non-users. Interestingly, different usage patterns were found for specific types of health apps. Theory and policy implications are discussed.  相似文献

网络隐私第三方认证机制初探   总被引：4，自引：1，他引：3  

董燕影  周庆山 《情报理论与实践》2009,32(5)

研究表明,由于担心个人信息得不到有效的保护,人们对使用基于互联网的各种服务心存疑虑,严重影响到电子商务的发展.旨在给电子商务的发展营造宽松的发展环境,在网络隐私法律框架之外,以美国为代表的国家产生了基于市场运作的网络隐私第三方认证.为了减少网络用户担心隐私遭到侵犯的不安全感,不少网站加入网络隐私认证计划.本文介绍了网络隐私第三方认证运行机制,以及在保护个人隐私方面存在的不足之处,并提出完善第三方认证机制的策略,以期对我国的个人信息保护提供新的思路.  相似文献   

Information management of medical errors in Greece: The MERIS proposal     

Athanassios Vozikis 《International Journal of Information Management》2009

There is a substantial amount of public concern about patient safety, as, according to estimates from major studies, hundreds of thousands die in hospitals each year all over the developed world as a result of medical errors that could have been prevented. Unprecedented research commissioned by the EU has found that almost one out of every four families has experienced a serious medical error. Greek citizens concerning about serious medical errors in the hospital environment, were at the top of the list. Greek Ombudsman's report on medical errors has raised the debate among health policy makers as to the appropriate response to the problem. Proposals range from the implementation of nationwide mandatory reporting with public release of performance data, to voluntary reporting and quality-assurance efforts that protect the confidentiality of error-related data. Any successful safety program will first require a national effort to make significant investments in information systems, along with providing an environment and education that enables to contribute to an active quality improvement process. In this paper we propose the development and implementation of Medical Error Reporting Information System (MERIS), in order to identify, collect, analyse and report medical errors and patient adverse events, as a tool for enhancing patient safety and health care quality. We also describe the necessary organisational structure and the infrastructure environment of the system and the barriers to its successful implementation.  相似文献   

The primary school’s invasion of the privacy of the child: unmasking the potential of some current practices     

Joan Hanafin  Marie Flynn  Michael Shevlin 《Educational studies》2010,36(2):143-152

Privacy has been defined as “the protective buffer within which people can avoid another party’s taking something from them, keeping watch over them, or entering into their lives in a way that is both unwelcome and undesirable”. It is a premise of this paper that such a position needs to be taken very seriously in contemporary society, and particularly in the case of schools, as school personnel have the capacity to engage in practices which show great disregard for individual and family privacy. This is illustrated in the case of primary school education in the Republic of Ireland. Particular attention is paid to assessment, pedagogical and curricular practices that derive from patterns of systematic and mandatory disclosure that are confessional, performative and public.  相似文献   

性犯罪被害人司法救助研究   总被引：1，自引：0，他引：1  

雍自元  唐胜 《安徽师范大学学报(人文社会科学版)》2010,38(6):729-733

性犯罪被害人是急需救助的弱势群体,而救助性犯罪被害人是司法机关的职责之一。与其他刑事被害人相比,性犯罪被害人精神损害尤为严重,精神损害赔偿的要求合理而强烈,为此司法机关应修改相关司法解释,赋予性犯罪被害人精神损害赔偿权。同时,在司法实践中保障她们的知情权和参与权;鉴于性犯罪被害人的敏感与脆弱性,司法机关在救助时应尊重其人格、保护其隐私。  相似文献
