Radio Frequency Identification (RFID) systems identify and track objects, animals and, in principle, people. The ability to
gather information obtained by tracking consumer goods, government documents, monetary transactions and human beings raises
a number of interesting and important privacy issues. Moreover, RFID systems pose an ensemble of other ethical challenges
related to appropriate uses and users of such systems. This paper reviews a number of RFID applications with the intention
of identifying the technology’s benefits and possible misuses. We offer an overview and discussion of the most important ethical
issues concerning RFID, and describes and examine some methods of protecting privacy.
Norman G. Einspruch serves as a consultant to several high-technology companies, one of which is in the RFID components and
systems business. 相似文献

The self-belief, motivation, tendency to procrastinate and learning styles of engineering students are discussed. It is proposed that engineering has developed an idiom and a learning approach that favours the dominant client, i.e. men, while simultaneously undermining the self-efficacy and motivation of women. Thematic coherence and teaching within a context that is familiar to students have been shown previously to be effective approaches for engaging students and are extended here to utilise the common experiences of all students to initiate the learning cycle. These approaches are combined with a template for teaching that uses the 5Es (Engage, Explore, Explain, Elaborate and Evaluate) in order to render the fundamentals of engineering more accessible to all students. This methodology can be introduced by individual instructors, who will be rewarded by students who are more engaged, more motivated and more likely to give a higher rating to the instructor and the course. 相似文献

Most students participating in science undergraduate research (UR) plan to attend either medical school or graduate school. This study examines possible differences between premed and non-premed students in their influences to do research and expectations of research. Questionnaire responses from 55 premed students and 80 non-premed students were analyzed. No differences existed in the expectations of research between the two groups, but attitudes toward science and intrinsic motivation to learn more about science were significantly higher for non-premed students. Follow-up interviews with 11 of the students, including a case study with one premed student, provided explanation for the observed differences. Premed students, while not motivated to learn more about science, were motivated to help people, which is why most of them are pursuing medicine. They viewed research as a way to help them become doctors and to rule out the possibility of research as a career. Non-premed students participated in research to learn more about a specific science topic and gain experience that may be helpful in graduate school research. The difference in the reasons students want to do UR may be used to tailor UR experiences for students planning to go to graduate school or medical school. 相似文献

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source. 相似文献

What Could Have Been Done? Circuit City: A Case Study of Management and Employee Performance Failure
Todd A. Campbell 《Performance Improvement》2014,53(4):16-23
This case study is an employee performance analysis that utilizes Gilbert's behavior engineering model (Gilbert, 2007 ) as a theoretical framework to examine the events that caused Circuit City to fail in 2008. Additionally, the case study views the events through a systemic lens. As management implemented changes, employee morale and performance faltered, which in turn affected customer perceptions and attitudes. Taken together, these actions resulted in a negative feedback loop that greatly contributed to the demise of the company. 相似文献

This article considers a secondary science department that has, since 2000, developed distributed leadership as a form of human capacity building. Using a longitudinal ethnographic case study allowed us to consider how distributed leadership can be nurtured and developed in a department. Our analysis centres on two key issues: the nature and pattern of distributed leadership practices and the continuity that provides coherence to those practices. From our analysis, there appear to be two major conclusions. The first of these is the need for administrators to be purposeful in the appointments that they make to formal leadership positions. To enact distributed leadership practices requires leaders who can exercise both formal power and influence. The second conclusion relates to the time required for continuity of leadership practices to give rise to changes that lead to teachers managing the teaching and learning programme. 相似文献
