Over the last two decades a new scholarship on alchemy has emerged, leading to a fundamental reformulation of knowledge about alchemists and their activities. We now know that medieval and early modern alchemists employed experiment in concert with theory to demonstrate the existence of stable "chymical atoms," which were thought to combine with one another according to a hierarchical theory of matter. Employing laboratory-based analysis and synthesis, alchemists were among the first explicitly to enunciate the principle of mass balance and to show that materials are compounded of the ingredients into which they can be physically decomposed. Perhaps even more surprisingly, these convictions and practices arose out of the interaction of alchemical practice with scholastic Aristotelianism, long viewed by historians of the Scientific Revolution as antithetical to experiment. Thus the new historiography challenges both a long-standing marginalization of alchemy itself and a commonplace view of Aristotelianism as inimical to the early modern growth of experimental science.  相似文献

The author chaired two Expert Groups of the OECD including that on privacy, whose guidelines form the basis of the legal regimes in Australia, New Zealand and many other countries. He reviews the success of those guidelines and the defects disclosed by time and by the remarkable advances in information technology since the guidelines were adopted in 1980. He then explores the revival of interest in the protection of privacy in the courts as a common law entitlement, instancing the recent decision of the Australian High Court in the Lenah Game Meats Case. The difficulty which the common law faces in responding to the challenge of informatics is then explored by reference to the decision in Dow Jones v Gutnik concerned with liability for defamation on the Internet. Finally, the author considers two contemporary problems: genetic privacy and terrorism. On the latter, he concludes with a reminder of the need to uphold civic rights, including privacy, so as to ensure that the terrorists, although losing, do not win.  相似文献

This essay addresses the other side of the robot ethics debate, taking up and investigating the question “Can and should robots have rights?” The examination of this subject proceeds by way of three steps or movements. We begin by looking at and analyzing the form of the question itself. There is an important philosophical difference between the two modal verbs that organize the inquiry—can and should. This difference has considerable history behind it that influences what is asked about and how. Second, capitalizing on this verbal distinction, it is possible to identify four modalities concerning social robots and the question of rights. The second section will identify and critically assess these four modalities as they have been deployed and developed in the current literature. Finally, we will conclude by proposing another alternative, a way of thinking otherwise that effectively challenges the existing rules of the game and provides for other ways of theorizing moral standing that can scale to the unique challenges and opportunities that are confronted in the face of social robots.  相似文献

Organizational knowledge, learning and memory have been popular topics for both academic research and practical applications over the past 20 years. But until now, these issues have been discussed independently and in a fragmented way. It is asserted that these concepts are interrelated and should be considered as a part of a system. Here, the perspective of the immune system is employed to integrate the issues of organizational knowledge, learning and memory into a framework and to explain their interrelationships. The perspective developed in this paper pioneers a micro-view to integrate and explain organizational phenomena.  相似文献

How can universities develop a knowledge management dynamic in order to train knowledge workers who are effective in an organizational learning process? Can games, and more specifically serious games, contribute to reaching this goal? To answer this question, we hypothesize that play can serve as a lever for knowledge management and double-loop learning. The purpose of this article is to show that serious games contribute to training knowledge workers in an organizational learning process. From this perspective, we attempt to understand how serious games promote the acquisition of knowledge and we explain the research method used in the field (participant observation, investigation using questionnaires). The final part analyses the main results: a community of practice and organization learning, internalization through Learning by Doing and better understanding of the environment’s complexity, towards double-loop learning and student satisfaction with the serious game.  相似文献

Information science, high-performance computing and artificial intelligence have boosted interdisciplinary topics in a wide range of domains, which calls for novel theories and methods specialized for the interdisciplinary research driven by information processing and management (IP&M)-centric methodology, frameworks and methods. In this article, we present a taxonomy of the IP&M_driven interdiscipline describing different levels of cross-disciplinary research paradigms centered around data, information and computing, and discuss opportunities and challenges confronted with the IP&M-driven interdiscipline development. We highlight the role of IP&M (and related disciplines, fields, or areas) in facilitating the interdisciplinary research and development.  相似文献

Cardiovascular diseases and allergic diseases occur commonly in developed countries. They lead to serious health complications and significantly impair the quality of life. Both types of diseases are characterized by excessive inflammatory processes. Recent studies suggest a link between allergy and an increased risk of cardiovascular disease, resulting from overactivity of the immune system in allergic diseases and increased synthesis of proinflammatory mediators, which has been well documented in the pathogenesis of atherosclerosis. The aim of this article is to present current data on the role of proinflammatory factors in the pathogenesis of cardiovascular diseases and allergies and on potential relationship between these disorders.  相似文献

网络关系强度作为表征企业网络的重要变量之一,理论界关于其对企业技术创新的影响尚存在较大的争议。本文以企业规模和研发投入作为控制变量,构建了网络关系强度、企业学习能力和技术创新三者之间的关系理论模型,并以申报广东省高新技术企业和民营科技型企业的企业为调查对象进行了实证检验。研究发现:(1)企业网络关系强度和学习能力都对技术创新存在着显著的正向影响。(2)企业学习能力在网络关系强度和技术创新之间起到不完全中介作用。(3)在小规模企业中,这三者之间并不存在相互影响的关系。本研究进一步深化了前人的研究结论,对组织网络及技术创新的相关研究都有学术贡献。  相似文献

Since its emergence in the 1980s, the concept of “Innovation Systems” (IS) has inspired research and shaped discussions in academia and policy alike, leading to a cascading development of approaches and extensions at various analytic levels. IS research has expanded far beyond its initial focus by generating new knowledge within but also attracting increased attention from adjacent fields. As a result, the broad understanding of IS and its diversity in applications has resulted in blurry boundaries of the field, making its contemporary delineation, synthesis, and assessment of its progress challenging. Using a combination of data-driven techniques from bibliometrics, natural language processing, and network analysis, this paper maps and analyzes the structure of knowledge production and the process of knowledge integration in current research. We find an overall growing tendency toward increasing diversity in the knowledge bases from which the field draws, accompanied by a decreasing coherence of collective research efforts. We point to the crucial role of institutions and academic entrepreneurs in shaping these developments in interdisciplinary and diverse fields, illustrating this by the role of the Organisation for Economic Co-operation and Development (OECD).  相似文献

We contribute to the literature on abandonment and innovation by showing the dynamic nature of the linkage between abandoned innovation activities and subsequent innovation outcomes at firm level. Based on a balanced panel of Spanish manufacturing firms from 2008 to 2016, we demonstrate that abandoning innovation not only leads to more successful innovation, but that there is an explicit time dimension to this. Firms which have prior experience of abandonment have stronger positive effects of more recent abandoned innovation activities on innovation output. However, these effects are largely restricted to prior experience from – and implementation in – the early (conception) phases of the innovation process. While firms systematically develop abilities to prevent failure, there is little evidence of learning from failure in terms of innovation abandonment.  相似文献

This paper explores what factors determine the nature, extent, and location of Japanese multinationals’ R&D activities abroad. Taking advantage of a rich micro-level dataset from the survey on Japanese overseas subsidiaries, the study distinguishes between two types of overseas R&D: basic/applied research and development/design. We find several differences between the determinants of those R&D activities. These differences confirm the view that basic/applied research of overseas subsidiaries aims at the exploitation of foreign advanced knowledge, whereas their development/design activities are mostly influenced by the market size of the host country. Our results provide a convincing and comprehensive explanation of the geographical distribution of overseas R&D by Japanese MNEs.  相似文献

The invention of partition chromatography by the biochemists Archer Martin and Richard Synge in 1941 offered crucial insights into the structure and function of DNA, insights at least as important as those from X-ray crystallography. Even so, the role that partition chromatography played in molecular biological studies is far less well known. Using new archival material, this article describes the origins of Martin and Synge’s work, arguing that their achievement was far more than a new technical innovation; it went on to have a profound impact on the development of molecular biology to an extent that scholars have insufficiently appreciated.  相似文献

Amartya Sen’s capability approach has become increasingly popular in development studies. This paper identifies controllability and operationalisability as two key stumbling blocks which prevent the capability approach from being used even more widely in development practice. It discusses the origins and application of the Choice Framework, a conceptual tool designed to help operationalise the approach. The framework can be used to deconstruct embedded ideologies and analyse the appropriateness of development goals, to map development as a systemic process, and to plan interventions which can result in increased freedom of choice for people. Three examples of the application of the Choice Framework in the field of information and communication for development (ICT4D) are given. The three technologies which are examined, telecentres (Infocentros), Chilecompra and Fair Tracing, can be placed at different places of a determinism continuum, some reducing the spectrum of choices a user has. The paper argues that while frameworks such as the Choice Framework can be developed further to increase the operationalisability of the capability approach, it is up to development funders to accept the fact that people’s choices are never fully predictable and thus Sen’s ‘development as freedom’ will inevitably be a dynamic and open-ended process.  相似文献

This paper aims to contribute to the conceptual debate on the connection between social innovation and social entrepreneurship, considering the role of the ‘social’ within this connection. Supported by a systematic literature review (SLR) with an in-depth analysis of 34 articles from Scopus-indexed and Web of Science databases journals, this paper identifies, analyzes and describes the difficulties and opportunities in the social innovation and social entrepreneurship literature. Little is known about the link between both concepts and the influence of the ‘social’ in their development and implementation. This SLR was conducted to identify and describe definitions and patterns. Results show that the connection between social innovation and social entrepreneurship is in its take-off phase, but it still is a fragmented field with a huge lack of consensus. Thus, it will be important to see where the field will head, as this paper aims to be a first step in the understanding of social innovation and social entrepreneurship through a collective and integrated perspective, providing an elucidation of the different perspectives of the literature.  相似文献
