由于现代科学技术的发展,相邻学科之间的相互渗透,分析化学的发展经历了三次巨大的变革,使分析化学发展成为以仪器分析为主的现代分析化学。面对生命科学中复杂的分离分析任务,发展了色谱分析方法。结构分析、价态分析、晶体分析等方面的研究又促进了光谱分析的发展。以计算机应用为主要标志的信息时代的来临,仪器分析迅速发展,为药物检测提供各种非常灵敏、准确而快速的分析方法。生物测定受到了极大的挑战,其发展前景令我们从事药品生物测定工作者所关注。面对目前的基本状况,阐明了生物测定专业在中药开发、新药研制、药物安全性评价及微生物限度检查方面的应用和发展趋势。 相似文献

Technology acceptance has spawned considerable research in technology adoption, technology use, and technology switching. However, technology choice—i.e., an individual’s selection of a technology from a set of technologies that support similar tasks—has received limited attention in information systems research. This research was aimed at identifying the drivers of technology choice through a series of activities in two universities, in which students chose an information technology tool from various alternatives to complete the given tasks. A thematic analysis was conducted on the reasons for technology choice reported by 249 students, which yielded 18 technology, user, and environmental drivers that influenced individuals’ technology choice. This study provides insights into the drivers generally applicable for technology choice and drivers applicable in specific contexts. Implications for research and practice are discussed. 相似文献

A sample of one hundred and eleven scientific instrument innovations was studied to determine the roles of instrument users and instrument manufacturers in the innovation processes which culminated in the successful commercialization of those instruments. Our key finding was that approximately 80% of the innovations judged by users to offer them a significant increment in functional utility were in fact invented, prototyped and first field-tested by users of the instrument rather than by an instrument manufacturer. The role of the first commercial manufacturer of the innovative instrument in all such cases was restricted, we found, to the performance of product engineering work on the user prototype (work which improved the prototype's reliability, ‘manufacturability’, and convenience of operation, while leaving its principles of operation intact) and to the manufacture and sale of the resulting innovative product. Thus, this research provides the interesting picture of an industry widely regarded as innovative in which the firms comprising the industry are not in themselves necessarily innovative, but rather — in 80% of the innovations sampled — only provide the product engineering and manufacturing function for innovative instrument users.We term the innovation pattern observed in scientific instruments a ‘user dominated’ one and suggest that such a pattern may play a major role in numerous industries. 相似文献

With the growth of high‐technology industries and knowledge intensive services, the pursuit of industrial competitiveness has progressed from a broad concern with the processes of industrialisation to a more focused analysis of the factors explaining cross‐national variation in the level of participation in knowledge industries. From an examination of cross‐national data, the paper develops the proposition that particular elements of the domestic science, technology and industry infrastructure—such as the stock of knowledge and competence in the economy, the capacity for learning and generation of new ideas and the capacity to commercialise new ideas—vary cross‐nationally and are related to the level of participation of a nation in knowledge intensive activities. Existing understandings of the role of the state in promoting industrial competitiveness might be expanded to incorporate an analysis of the contribution of the state through the building of competencies in science, technology and industry. 相似文献

纵向视角下中国技术转移系统演变的协同度研究——基于复合系统协同度模型的测度 总被引：2，自引：0，他引：2
从纵向视角出发,结合系统论,对技术转移系统进行概念界定及结构解析。在此基础上,选择合适的序变量,基于2000-2009年相关数据,运用复合系统协同度模型对我国技术转移系统演变的协同度进行实证分析。结果证明,我国技术转移系统的协调发展程度不高,且呈现波动演变态势,其中,技术传播子系统是影响我国技术转移系统演变过程中协同度发展方向和程度的关键因素。最后,针对我国技术转移系统协调度的现状,为宏观调控者提供了政策性建议。 相似文献

The paper defines and validates a scale—CC-Qual—to assess the quality of services provided through a Collaborative Consumption (CC) model.The authors have borrowed a set of items arranged in eight dimensions from the literature on CC. A panel of selected practitioners (seven CEOs of CC companies) assisted in the design of the questionnaire, which was launched in June 2018. A sample of 127 questionnaires was used for exploratory factor analysis. A second sample of 301 users was used for confirmatory analysis using EQS 6.4 software.A scale of 21 items gathered under five dimensions is proposed. Accordingly, the perceived quality in CC is composed of five dimensions: three of them related to the interaction with the platform (“site organization”, “platform responsiveness and agility” and “legal protection and trustworthiness”), another related to the perceived quality of the peer service supplier (“peer service provider”) and the last one to assess the encounters with other consumers and with the person who provides the service (“social interaction”).This study provides a useful measure for the assessment of the perceived quality of CC services, regardless of the activity sector. This instrument might assist managers for both assessing and benchmarking. The instrument also provides independent and reliable information for customers. 相似文献

Cloud computing providers and their software-as-a-service offerings have become more profuse and mature, making cloud technology an increasingly important platform for business services innovation. Although the cloud offers rich opportunities for transforming businesses—innovating existing services and introducing creative new ones—it also involves risks that business managers must identify and resolve to successfully drive innovation efforts. However, no comprehensive models are available to help managers assess and mitigate the risks they face. To address this void, we reviewed extant literature on cloud computing from a business innovation perspective to uncover the myriad challenges managers confront as they seek to leverage cloud technology in the ongoing transformation of their organization’s service offerings. Combining this systematic literature analysis with relevant theory, we synthesized an integrated model for managing risk during innovation of cloud-based business services. The model identifies three types of risks (services, technology, and process risks) and four types of resolutions (stakeholder engagement, technology development, innovation planning, and innovation control). The model also helps managers identify their organization’s general risk profile and link that profile to a specific configuration of resolutions. 相似文献

在协同研发的背景下,多技术知识主体参与、多技术知识资源融合成为共性技术研发和溢出的主流范式,揭示跨领域搜索、产业联盟和共性技术溢出之间的关系,是现实驱动的结果。本文针对当前研究对“共性技术溢出如何产生”这一问题关注不足的现状,从企业“搜索行为”出发,基于专利分析法和内容分析法,构建了373家企业专利数据样本和190家企业产业联盟数据样本,通过实证研究发现：跨领域搜索对共性技术溢出的影响存在双刃剑效应,而产业联盟特性在二者关系中起到放大作用。主要研究结论是：（1）跨领域搜索与共性技术溢出深度存在倒U型关系;（2）跨领域搜索与共性技术溢出广度存在倒U型关系;（3）产业联盟的数量在“跨领域搜索-共性技术溢出深度”“跨领域搜索-共性技术溢出广度”的关系中均存在正向调节作用;（4）产业联盟的异质性在“跨领域搜索-共性技术溢出深度”“跨领域搜索-共性技术溢出广度”的关系中均存在正向调节作用。本文在一定程度上向前延伸了共性技术溢出的前因研究,并为企业和政府提供一定的现实借鉴意义。 相似文献

环保产业是连接环境与经济的桥梁,是“十三五”时期国家的重点建设内容,为更有效地促进环保产业发展,有必要对众多环保产业政策工具进行比较。本文基于国外经验及中国实际构建了中国环保产业政策工具分类的概念模型,并在此基础上应用中国环保产业营业收入和三类六项政策工具的1995-2014年数据构建GRA-VAR模型,通过测度政策工具对环保产业的重要程度及影响比较环保产业多项政策工具。研究得出：在促进环保产业发展三类政策中,科技政策工具最优、经济政策工具次之、法制政策工具最弱。其中,科技政策工具中代表成果的细分工具在六项细分工具中排名第五;经济政策工具作为经济手段,其与环保产业的关联程度高于另两类行政手段与环保产业的平均关联程度。 相似文献

The high technology debate in Australia since 1981 is analysed using one of the most prominent features of the debate — he political rhetoric and symbols used in the debate. This form of analysis emphasises both instrumental and expressive political activity. The high technology debate is seen as having a significant expressive component and function. Most of the advocacy for high technology came as a result of institutional pressures and efforts of the Minister for Science and Technology, Barry Jones. High technology became a ‘maverick’ term in political debate but it has now become an accepted part of current economic language. The paper draws a number of conclusions for policy from the analysis. 相似文献
