The field of science and technology studies provides three landmarks useful for orienting the loose constellation of intellectual projects pursued under the rubric of Internet research. Interdisciplinarity, networks, and politics offer a foundation from which social change and progress can be assessed. These landmarks can help to examine the rapid change, the micro and macro connections, the constraints and possibilities for self-organization that stand to reconfigure the substance of power, class, and culture associated with the adoption of new communication technologies. 相似文献

Pulp and paper is a major impact industry, in which environmental impacts can be seen to be complex, diverse and characterised by uncertainty and interdependence. A greening process within this industry requires wide ranging environmental knowledge. Also fundamental are effective networks for information exchange and greening is therefore dependent on changes to such networks. This study investigates the issue of how greening occurs, focusing on the process at the Fletcher Challenge New Zealand integrated pulp and paper mill situated in Tasmania, Australia. It was seen that effective greening within this industry relies on information processing capabilities to access external and internal knowledge and skills, and that this is fundamentally dependent on structural arrangements. Appropriate organisational structure and external networks are therefore essential for accessing information and facilitating its dissemination and integration, thereby enhancing the firm's ability to address environmental concerns. The study highlights interaction between the formal change process, one which sought limited change, and an informal change process that continued greening the company beyond the official aims. The reasons for this are located in the power of informal information exchange. 相似文献

IntroductionIt is common for patients to switch between several healthcare providers. In this context, the long-term follow-up of medical conditions based on laboratory test results obtained from different laboratories is a challenge. The measurement uncertainty in an inter-laboratory context should also be considered in data mining research based on routine results from randomly selected laboratories. As a proof-of-concept study, we aimed at estimating the inter-laboratory reference change value (IL-RCV) for exemplary analytes from publicly available data on external quality assessment (EQA) and biological variation.Materials and methodsExternal quality assessment data of the Reference Institute for Bioanalytics (RfB, Bonn, Germany) for serum creatinine, calcium, aldosterone, PSA, and of whole blood HbA1c from campaigns sent out in 2019 were analysed. The median CVs of all EQA participants were calculated based on 8 samples from 4 EQA campaigns per analyte. Using intra-individual biological variation data from the EFLM database, positive and negative IL-RCV were estimated with a formula based on log transformation under the assumption that the analytes under examination have a skewed distribution.ResultsWe estimated IL-RCVs for all exemplary analytes, ranging from 13.3% to 203% for the positive IL-RCV and - 11.8% to - 67.0% for the negative IL-RCV (serum calcium - serum aldosterone), respectively.ConclusionExternal quality assessment data together with data on the biological variation – both freely available – allow the estimation of inter-laboratory RCVs. These differ substantially between different analytes and can help to assess the boundaries of interoperability in laboratory medicine. 相似文献

Abstract During the late 1990s, photography moved from being a primarily analogue medium to being an almost entirely digital medium. The development of digital cameras and software for working with photographs has led to the wholesale computerization of photography in many different domains. This paper reports on the findings of a study of the social and organizational changes experienced by marine mammal scientists who have changed from film‐based photography to digital photography. This technical change might be viewed as a simple substitution of a digital for an analogue camera, with little significance for how scientists do what they do. However, a perspective anchored in social informatics leads to the expectation that such incremental technical changes can have significant outcomes, changing not only how scientists work, but also the outcomes of their research. This present study finds that key consequences of this change have been the composition of the personnel working on the scientific research teams for marine biology projects and the ways in which these scientists allocate their time. 相似文献

The Bell Labs of decades ago was well recognized as a national treasure for its pioneering innovations and its creation of new knowledge. However, the breakup of the Bell System that occurred in 1984 resulted in considerable change for research and development in telecommunication. This paper reviews that history and, in anticipation of continuing uncertainty and a possible impending crisis, examines possible options for the future to assure leadership by the United States in basic research in telecommunication. 相似文献

Abstract The information age is bringing about a change in the world division of labor. Many of the great trading cities that arose during the Industrial Revolution as shipping, railroad, and financial centers are now facing new challenges, challenges brought about by global telecommunications. Information technology and the changing nature of business and government offer new opportunities and threats to these and other cities as they strive to acquire or retain treasured economic activity. Telecommunications and computation capacity are among the tools cities can use as they vie with one another for this commerce. This study describes how U. S. cities are affected by these trends and summarizes some of the key technological and policy issues involved. Several case studies are reported, which show the various strategies used by large cities such as New York and Boston, progressive Midwest cities such as Omaha, and small cities such as Heathrow, Florida. Some preliminary principles of success are adduced. 相似文献

Abstract This paper provides a detailed analysis of the change process of academic science. The change pressures currently visible in UK science have been conceptualised as the product of three interdependent dynamics: a shift towards neo‐liberal ideologies and discourses of government; a process of reconstitution of the relationship between government and science; and the resulting reshaping of science itself. Focusing on the universities and academic science, we argue that this process of transformation has adverse consequences the end result of which may be a loss of capacity within the science system to maintain knowledge bases. 相似文献

Diabetes Mellitus in obese and non-obese Indian individuals.AIMS: Effect of Obesity and insulin resistance on diabetic control.SETTINGS AND DESIGN: 50 each groups Diabetic individuals obese and non-obese.METHODS AND MATERIAL: On selected 50 each group diabetic patient and normal, following blood investigations has been performed—Plasma Glucose,
Glycohemoglobin and Serum Insulin.STATISTICAL ANALYSIS USED: Individuals patient’s results were analyzed and compared with the normal controls.RESULTS AND CONCLUSION: The changes in glycosylated haemoglobin are mainly proportional to the post lunch glucose level (r=0.773) (p<0.01) and not
correlated to circulating insulin or the body mass index. However the levels were higher in obese diabetes (Type I and II
both) than in non-obese. Mechanism of resistance in insulin receptor interactions due to obesity is well known. However, obesity
does not seem to affect directly glycosylated haemoglobin. Under such circumstances, the reduction of weight for a diabetic
person can improve sugar control by minimizing insulin resistance and thereby can improve glycosylated haemoglobin levels. 相似文献

In April 1997, Tasmania (Australia) adopted the reputably successful New Brunswick (Canada) industrial strategy to build an information technology (IT) industry of significance. The strategy aims to overcome isolation in small regional economies and structurally change from declining natural resource industries. Both plans reject neo-classical economics-based industry policy, opting instead for a strong state-based investment planning approach. An analytical framework is set out, using Adolph Lowe's 'Instrumental Analysis', to examine implementation of both IT strategies. Implications of this analysis are drawn for any attempts at developing IT regional plans and, more generally, as a guide for broad strategic-based national industrial strategies. 相似文献
