Telecare’ refers to the use of digital or information and communication technologies (ICTs) to facilitate health and social care delivery to individuals in their homes. This article explores the phenomenon by foregrounding its interconnections with work activities, paid and unpaid. It draws on research as a part of the design and deployment of a set of telecare innovations for older people in an Italian municipality. The project was conceived at the outset in terms of formal inter‐ relationships between functions and components of technical systems. Technical setbacks, however, were resolved only by enrolling the active support of groups and individuals (including civil society organisations and older people). By situating a telecare intervention conceptually within the ‘total social organisation of labour’ (TSOL), we provide an analysis that contributes to understanding how a socio‐technical infrastructural approach to telecare reveals ways to improve our understanding of how formal and informal care systems interact.  相似文献

Food sharing mobile applications are becoming increasingly popular, but little is known about the new social configurations of people using them, particularly those applications that use consumers as voluntary intermediaries in supply chains. This article presents a social network analysis of a food sharing mobile application conducted in partnership with OLIO. The study focuses on longitudinal social network data from 54,913 instances of food sharing between 9054 people and was collected over 10 months. The results challenge existing theories of food sharing (reciprocity, kin selection, tolerated scrounging, and costly signalling) as inadequate by showing that donor-recipient reciprocity and balance are rare, but also show that genuinely novel social relations have formed between organisations and consumers which depart from traditional linear supply chains. The findings have significant implications for managers and policymakers aiming to encourage, measure and understand technology-assisted food sharing practices.  相似文献

Social networks are an important driver for successful innovation, both at the individual level as well as the organizational level. Recent research has also shaped that networks within teams can enhance performance. Innovative project teams are embedded in an organizational context, however, and teams typically consist of people with expertise from diverse backgrounds, and from different units. Team members may have ties to other teams, business units, and hierarchical levels. Although it seems clear that such ties can influence team performance, remarkably little research has focused on what is here referred to as vertical and horizontal cross‐ties. Previous research may have ignored the possibility that vertical and horizontal bridging ties may have different performance outcomes. Although the literature suggests that diversity of input, or horizontal cross‐unit ties will benefit team performance and innovativeness, there is reason to believe that ties to higher levels in the organization might have an effect on project team performance and innovativeness too. This article in particular studies the role of vertical cross‐hierarchy ties. In an exploratory analysis combining quantitative and qualitative results, it is distinguished between horizontal cross‐unit and vertical cross‐hierarchy ties and their contribution to new business development (NBD) project performance, thereby making a substantial contribution to both academic literature and managerial practice. Our study is based on a multiple case‐study approach of several NBD project teams in a large European financial service provider. Our results show that successful innovation project teams are characterized by a large number of cross‐unit ties in combination with a large number of cross‐hierarchical ties compared with less successful project teams. Additionally, proof is found that vertical cross‐hierarchy ties should be concentrated rather than scattered across project members.  相似文献

This paper raises the question of the philosophical base of a liberal technology education, assuming that it cannot be provided simply by an engineer's perspective. It therefore reconstructs known ideas about technology in terms of the social relationships inherent in the development, gestalt and use of technical artifacts. The outcomes of this reconstruction are perceptual relationships in the phenomenology of technology, power relationships in critical theory, and artifact-designer relationships in social constructivism. Based on these outcomes, the paper suggests a series of questions for reconstructing the cultural meaning of technology and a structural model that shows how meaning is generated through a variety of social relationships. The final section deals with the educational implications of this approach. These include a shift from teaching content matter isolated from social considerations towards a dialectic engagement with the social and technical dimensions of technological activity in order to make technology education meaningful for all students.  相似文献

Although successful new product development practices often require joint efforts of professionals from various departments, all too often these professionals are trained as specialists with little exposure to other functional viewpoints. Colin Clipson describes the results of an educational initiative designed to bring together selected technical, business and design students enrolled in classes at The University of Michigan. Members of various student teams quickly ascertained a need to overcome language and cultural barriers in order to develop product recommendations for sponsoring firms. The results of this educational experiment have implications for current educational programs as long as improved innovation management is seen as a desirable social goal.  相似文献

The literature on Smart Cities has not as yet paid adequate attention to the rural sector, and the potential in villages for creating smart and sustainable solutions for the 21st century. This paper focuses on linking proposed smart city strategies to smart village policies to ensure that rural youth have improved opportunities for employment through ICT initiatives to ensure digital inclusion, using primary surveys undertaken in India. The motivation was to understand how mobile telephony could be a catalyst to create Smart Villages in India, where young people can chart out new pathways to realize their aspirations with regard to tertiary education and new avenues for diversifying into rural non-agricultural employment. We use data obtained from a household survey in villages in the states of Punjab and Tamil Nadu to examine the mobile phone usage preferences of rural educated youth to identify the way forward in improving the accessibility of services on the supply side. We make the case that where youth are using mobile phone access to increase their social information base it is indeed possible that the new social media groups formed by rural youth become a powerful conduit for generating new employment opportunities. The key to accessing this solution is to use a demand driven model for mobile services that would permit a bottom of governance model to generate sustainable growth of enterprises and improved human development of these villages.  相似文献

This paper investigates the price effects of cash versus mortgage transactions. Our hypothesis that home sales involving all-cash transactions will sell at discount is borne out by the results of this study. Analyzing a sample of comparable row home dwelling units, we find that all-cash transactions are associated with roughly a 13% price discount relative to transactions involving financing terms that are typical of the market. Cash is King. The findings are consistent with theories regarding buyer—seller behavior.  相似文献

Rapid social change creates a powerful challenge to individuals and educational institutions. Technology education is not an exception. To be a useful and authentic learning area, technology education should constantly re-examine its rationale in order to formulate responses to changing contexts to improve the quality of learning for students. The more perspectives used for this process, the better the results should be. This article explores several facets of social change that can influence an understanding of the aims and nature of technology education and that might contribute to its development. Social change is a very complex and dynamic phenomenon that can be considered from a variety of perspectives and is reflected in a number of processes. These processes are different in different types of societies. In relation to the topic, the following processes that are relevant to Western societies (it is acknowledged that for different type of societies, e.g. Islamic, Chinese, social context will be different) will be analyzed: (1) The shift of emphasis from engaging society members primarily as producers to engaging society members primarily as consumers; (2) The colonisation of the cognitive and moral spheres of human life by the aesthetic sphere; (3) The integration of people into the technological world and (4) The shift from the Welfare state to the Competition state. These processes have been identified on the basis of their potential influences on the development of technology education and, as a consequence, the students who study it. These processes are in tension which creates even greater challenges to technology education. Several implications of the above analysis in terms of conceptualizing technology education are discussed. It is suggested that social change can be addressed through technology education if the educational goals of it are ‘to broaden minds and develop all pupils in the creation of a better society’. For technology education classrooms, these specifically mean the involvement of students in democratic debates on the future outlines of technological development; development of their social and ecological sensitivities; avoiding orienting their solutions exclusively to the standard of business efficiency and profitability criteria; helping them to distinguish real needs from desires; discussing the role of designed objects in the life of contemporary society; putting more emphasis on other than the aesthetic aspects of life that can provide existential meaning for people; challenging the way people are manipulated through advertising and cultivation of their desires; developing an active/creative attitude towards problems (not re-active); teaching students to formulate problems (not only being involved in problem solving); challenging consumer-oriented design; looking at design as one source of inspiration, not as a source of economic utility; and developing social responsibility  相似文献

Vocational training incidence for those at work is frequently financed partly or wholly by employers, who then lose part of their investment return if workers migrate to other firms. We investigate the incidence of training and the incidence of job-to-job mobility for a large sample of British workers in 1984 and 1989. We also analyse the role of sectoral technology characteristics in influencing patterns of both training and inter-firm mobility.
Our results demonstrate that job-to-job mobility is highest for the young and higher for those with formal educational qualifications than for the unskilled. These are also characteristics which engender a higher training propensity; so, unavoidably, private gains to training for employers are below social gains for these young people. Public-sector workers have high training rates but low mobility; this perhaps explains the lack of perception of the poaching problem by successive governments. Sectoral R&D activity is associated with more training and less mobility for men; in contrast, women are more likely to train and are less mobile if the rate of adoption of innovation is rapid.  相似文献

This paper investigates the evolutionary dynamics of network formation by analyzing how organizational units create new interunit linkages for resource exchange. Using sociometric techniques and event history analysis, this study predicts the rate at which new interunit linkages are created between a newly formed unit and all the existing units in a large multinational organization. Two important constructs: social capital, derived from the literature on social structure and network formation, and strategic relatedness, derived from research on diversification and the resource‐based view of the firm, are used to explain the rate of new linkage creation. Results show that the interaction between social capital and strategic relatedness significantly affects the formation of intraorganizational linkages.

This study investigates the impact of two organizational antecedents, (1) Six Sigma resources (technical) and (2) team psychological safety (social), on learning behaviour and knowledge creation and, in turn, on the success of Six Sigma process improvement projects. The paper proposes an integrated model to explain process improvement implementation success through two learning activities undertaken by Six Sigma project teams: Knowing-what and Knowing-how. The conceptualization of these knowledge types in this research is different from usual conceptualization as it represents the knowledge brought into projects through various phases of Six Sigma projects. The three hypotheses proposed in the model were tested using the data collected from 52 Six Sigma project teams from a single organization. Regression analysis showed psychological safety affects project performance through knowing-how. Regression and bootstrapping analyses showed resources influence project performance through the combined mediation of knowing-what and knowing-how.The paper provides an interdisciplinary treatment of knowledge management in process improvement teams, and offers a research model demonstrating how Six Sigma project teams promote deliberate organizational learning. By doing so, this study empirically establishes the notion that technical and social supports jointly impact the success of operations management initiatives such as Six Sigma through learning. The limitations of the study along with the future research directions are highlighted.  相似文献

Cognitive radio (CR) is still an emerging and disruptive communication technology which is expected to improve the overall efficiency of the spectrum use. It is envisaged that cognitive radio systems (CRS) could impact many aspects of communications and in particular could facilitate accommodation of the increasing amount of services and applications in wireless networks. Intensive research on CR aims at maximising the utilisation of the limited radio spectrum resource. There have been many advances in CR regarding the technology development aspects; however supplementary research on regulation, policy and market structure reforms in relation with application specific deployment is still required before any CR-based spectrum access could be implemented for specific broadband mobile applications. Indeed, mobile community is still at an early stage of understanding and development of CR capabilities and it is premature to envisage wide deployment of CRS without careful consideration of regulatory and business issues. Therefore, this paper gives a classification of CR-based network and application scenarios, and investigates the feasibility of them from a regulatory perspective at a global level (ITU-R). Main part of this paper presents the wireless network operator’s approach to CRS specific for International Mobile Telecommunications (IMT) systems and proposes the radio environment map (REM) concept as a cognitive tool that increases environmental awareness in wireless network operator’s networks. Studies, which the authors performed internally and within the framework of a collaborative European project as well as within ITU-R yield the conclusion that, at shorter term, only intra-operator based CRS maximises the possibility for CR capabilities to be implemented.  相似文献
