Dominant discourses on telecare technologies often celebrate the erasure of distance and place. This paper provides a critical intervention into these discourses by investigating how spaces still matter, despite the move from physical to virtual encounters between healthcare professionals and patients. I argue that science and technology studies (STS) research on telecare, as well as other technologies, can be enriched by including a focus on place to understand the dynamic interactions between people and things. Adopting insights of human geographers, I show how places in which technologies are used affect how technologies enable or constrain human actions and identities. Whereas some spaces may facilitate the incorporation of technologies, others may resist technologies. A focus on how places matter is important for understanding how telecare technologies reorder and redefine healthcare. Although other healthcare technologies are also important actors in transforming healthcare, telecare technologies do this in a very specific way: they redefine the spatial dimensions of healthcare. To capture and further explore this changing spatial configuration of healthcare, I introduce the notion of technogeography of care. This concept provides a useful heuristic to study how places matter in healthcare. Although telecare technologies introduce virtual encounters between healthcare providers and patients, the use of telecare devices still largely depends on locally grounded, situated care acts. Based on interviews with users of several cardiac telecare applications, including healthcare professionals and patients in Germany and The Netherlands, the paper shows how patients' homes and public spaces are important for shaping the implementation and use of telecare technologies, and vice versa. Last, but not least, telecare devices are implicated as well. The paper emphasizes the place-dependency of the use and meaning of technical devices by showing how the same technological device can do and mean different things in different places. 相似文献

While Interactive systems such as Chatbots, are well known in personal environments with technologies like “Apple’s Siri” or the “Google’s Assistant”, the acceptance of said technologies in the enterprise context has hardly been examined. Literature shows that these technologies hold great potential for enterprises as they can increase productivity and are cost-efficient by automating processes. Still, to not alienate employees when introducing these systems called Enterprise Bots in this paper, it is crucial to understand how employees accept and adopt these new systems. This paper derives a research model based on the decomposed Theory of Planned Behaviour, which is tested in a survey with 198 participants. Results from a structural equation model show that intrinsic motivation of the employees has a strong positive influence on the intention to use Enterprise Bots whereas external influences showed smaller effects. The results indicate that it is important that employees are convinced of the usefulness of a tool for themselves. The paper provides theoretical insights and helps decision makers to introduce such systems. 相似文献

The last two decades have witnessed a significant increase in discussions about the different dimensions of knowledge and knowledge management (KM). This is especially true in the construction context. Many factors have contributed to this growing interest including globalisation, increased competition, diffusion of new ICTs (information and communication technologies) and new procurement routes, among others. There are a range of techniques and technologies that can be used for KM in construction organisations. The use of techniques for KM is not new, but many technologies for KM are fairly new and still evolving. This paper begins with a review of different KM techniques and technologies and then reports the findings of case studies of selected U.K. construction organisations, carried out with the aim of establishing what tools are currently being used in U.K. construction organisations to support knowledge processes. Case study findings indicate that most organisations do not adopt a structured approach for selecting KM technologies and techniques. The use of KM techniques is more evident compared to KM technologies. There is also reluctance among construction companies to invest in highly specialised KM technologies. The high costs of specialist KM technologies are viewed as the barrier to their adoption. In conclusion, the paper advocates integrated use of KM techniques and technologies in construction organisations. 相似文献

Abstract In an effort to confront the key issue of where the information society is leading us, this essay begins where most discussions leave off: if advanced industrial societies are dedicating increasingly greater resources to the use of information services and technologies, what is the value of information in organizational and governmental processes? To assess the value of information: information technology, information/library science, information resource management, value/burden, organizational theory, and the economic theory of information. Based on this overview, we propose a conceptual framework which is sensitive to the major objectives and assumptions of previous approaches, but which also attempts to expand the criteria for the assessment of information value. 相似文献

The usage of communication networks provides a backbone of integration of information technologies and load frequency control (LFC) scheme. Time delays introduced by network environments taking the new challenge for dynamic performances and even the stability of closed-loop LFC scheme. This paper focuses on the stability and stabilization of multi-area LFC schemes for power systems with the introduction of communication networks and renewable energies. Markov theory is exploited in this paper for describing the discrete time-delay mechanism. Then, by utilizing Wirtinger-based inequality, and constructing a novel Lyapunov functions, the results of robust stability and stabilization criteria are derived in terms of linear matrix inequality (LMI). Finally, simulation results are provided to demonstrate the effectiveness and superiority of developed results. 相似文献

At present, the research and development in the food processing technology sector have generally been driven by the large manufacturing drivers that enhance the effectiveness of the economic scale. Increasing demand for high-quality, innovative texture-building foods, consumer requirements for customized products (i.e., fat, sugar, and micronutrient content), and the limited availability of ingredients and services are pressuring the business industry to use innovative technology to allow a more sustainable food supply. People need a successful approach for potential industrial technologies, and one of the key elements of the industry is Sustainable Food Smart Manufacturing Technology (SFIMT). Advanced methods and techniques are needed to select the appropriate alternate for SFIMT technologies. This paper summarizes technology in food processing and presents a modern framework to guide potential assessments. An innovative empirical evaluation method is proposed to provide several criteria for recognizing the suitability of different food technology for future SFIMT systems. Finally, the analysis value is investigated by utilizing the evaluation method for a number of chosen innovations with promising prospects in future food processing. 相似文献

Management effectiveness is strongly influenced by the quality and availability of the information resource available to managers. This is partially dependent upon the information and communication technologies which transport events, data and knowledge from isolated consciousness to individual and collective awareness. However, the use of these technologies rarely occurs in isolation. Rather, it is embedded in a far wider organisational context which recognises the politics of decision making and technical change, and the broader culture and experiences of organisations. Central to this is understanding how information technology (IT) investments cause organisations to reflect on the importance of their processes of communication and the value they place on information. A key part of this organisational flux acknowledges that IT applications are built on the existing systems, structure and past experiences of the organisation. Accordingly, investments in IT form part of an ongoing organisational development. Such intangible aspects create a dilemma for management in that they prove problematic to evaluate using conventional approaches to cost justification. By drawing on a series of case studies, questionnaires and interviews, this paper suggests a fresh approach to this dilemma by developing the concepts of dependency, legacy and heritage. The paper concludes by recognising that current approaches to investment appraisal emphasise a narrow, short-term perspective which focuses on a single investment, rather than on a continuous investment stream. 相似文献
