In this paper we will try to address technological diffusion and substitution from two methodological angles. The first consists in a complete and comprehensive morphological analysis (MA) of a set of (process) technologies for a particular industry. In the second part, we use the results of our MA of the technological trajectories in the casting industry, to analyse their diffusion in two countries, France and the FRG. With respect to the results of this work, we can express two observations. First, this case study will provide valuable insights on the conditions of exit from a “lock-in” situation. Second, the MA will permit us to avoid misinterpretation concerning the asymmetrical character and discontinuities of the diffusion trajectory of the technology under consideration.  相似文献

The size of patent applications has doubled over the past two decades, resulting in a dramatic surge in the workload of patent offices all over the world and serious concerns over patent quality standards. The current paper investigates the sources of this inflation in claims and pages for EPO applications. Four hypotheses are quantitatively examined: the diffusion of national drafting practices, the complexity of research activities, the emergence of new sectors, and filing strategies. The results validate the four hypotheses. They reveal major differences across countries in patent drafting styles, especially between Civil and Common Law countries, the latter being characterized by much larger patents. Second, the success of the PCT route is leading to the harmonizing of drafting styles worldwide on the US model. This paper therefore challenges the commonly accepted idea that more claims reflect a broader scope of protection by showing that the size of patents is partly due to institutional changes in the system.  相似文献

遗产包括代际之间物质和非物质的交流,各个群体和团体随着其所处环境、与自然界的相互关系和历史条件的变化不断使这种代代相传的物质的和非物质的遗产得到保护和创新,同时使他们自己具有一种认同感和历史感,从而促进了文化多样性,激发人类的创造力。但是目前这种交流的客观事实或性质以及历史维度在遗产保护中并没有给予足够的重视。本文针对遗产在当地社区身份中的重要性,以及地方身份是否在当地居民中产生了对遗产保护的积极性等问题进行了探讨,调查了遗产及其保护是否以及如何成为社区复兴、保护意识、社区建设及公众参与的一个组成部分。因此,当地居民的态度及其期望是非常关键的因素。本文对在比利时弗兰德地区根特城市核心区工业化前的邻里关系进行了考察,并进行了大量的参与式图片调查。尽管其历史渊源相当独特,但当地居民反对退化和支持保护的动机却具有更加普遍的价值。  相似文献

What I consider in this paper are various forms of government, various technologies and discursive regimes of government that are in common use today. What interests me are the categories and tools, practical dispositifs and languages that developed over the last decades ‘to constitute, define, organize, and instrumentalize the strategies that individuals, acting freely, may use to deal with one another’ (Foucault). The paper considers first the neo-liberal wish to reassert the individual as alone in responsibility for his/her own life after the unfortunate digression into Welfare Statism and Keynesian economics, source of all ills. It then focuses on some material and social technologies that encourage people to accept full and complete ‘self-sovereignty’. This section leads to a discussion on the new demands (and resistance) society imposed on this liberal normative ideal. It notably considers the growing demands to ‘participate’ in decision processes and to be environmentally friendly. In section “Les Mots et Les Choses: A New Discursive Regime”, it considers the discursive regime that progressively took shape and which currently permeates international governance bodies of all stripes—from the World Bank to the Conference of Parties for Climate Change. In the final section, it comes back to the initial question and considers what these changes actually mean for the democratic order as constituted over the past 250 years.  相似文献

To date, hardly any evidence is available on the quality of adult education programs for vulnerable adults. Evaluation instruments or models mostly focussed on regular education and less on programs of adult education aiming to enhance social inclusion. This study presents a first exploration of the construct validity of a newly developed instrument, called the SIT-instrument (social inclusion after transfer) for the evaluation of educational programs for vulnerable adults and their impact on increasing social inclusion. The sample consisted of 308 respondents belonging to the target-group of vulnerable adults. The results of the validation study indicate a reliable instrument consisting of elements of a learning-environment for “vulnerable” adults influencing 4 specified categories of social inclusion.  相似文献

This study presents characterizations of weathering forms of the same oolitic limestone from four quarries and eight monuments exposed on various environmental conditions focusing on the waterproofing effect of endolithic organic matter. Patinas were analyzed by X-ray diffraction (XRD), scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDX), capillarity coefficient through weathered and unweathered sides, gypsum content and porous network morphology by epoxy resin molding. Study of weathering forms on old quarries indicates that lichens colonization (Verrucaria nigrescens and Caloplaca aurantia) can fill the superficial porous network with a dense network of lichenised fungal hyphae. Capillary coefficient measurement on natural and calcinated samples showed that endolithic organic matter can waterproof the stone and could act as a sulfate contamination barrier. Similar endolithic organic layer due to ancient lichens growth are found on some antique monuments of the Nîmes downtown and could explain their well-preserved state, unlike decayed 19th century churches that were never colonized by lichens.  相似文献

There is a growing trend to offer students learning opportunities that are flexible, innovative and engaging. As educators embrace student-centred agile teaching and learning methodologies, which require continuous reflection and adaptation, the need to evaluate students’ learning in a timely manner has become more pressing. Conventional evaluation surveys currently dominate the evaluation landscape internationally, despite recognition that they are insufficient to effectively evaluate curriculum and teaching quality. Surveys often: (1) fail to address the issues for which educators need feedback, (2) constrain student voice, (3) have low response rates and (4) occur too late to benefit current students. Consequently, this paper explores principles of effective feedback to propose a framework for learner-focused evaluation. We apply a three-stage control model, involving feedforward, concurrent and feedback evaluation, to investigate the intersection of assessment and evaluation in agile learning environments. We conclude that learner-focused evaluation cycles can be used to guide action so that evaluation is not undertaken simply for the benefit of future offerings, but rather to benefit current students by allowing ‘real-time’ learning activities to be adapted in the moment. As a result, students become co-producers of learning and evaluation becomes a meaningful, responsive dialogue between students and their instructors.  相似文献

This paper describes how a short, repeated and structured opportunity to reflect was integrated in the storyline of a serious game in order to stimulate the development of a meta-cognitive skill: the ability to self-assess the degree of confidence in own answers. An empirical validation of the approach, conducted with 28 secondary school pupils, delivers an uncommon pattern: while the cognitive benefits—the acquisition of academic knowledge in optics—are negligible and mixed up, the meta-cognitive gains present a raising tendency. The experiment also demonstrates that reflection does not necessarily hamper the game flow, if certain conditions, discussed in the paper, are met.  相似文献

A frequent critique of contemporary journalism is that journalists rarely adjudicate factual disputes when covering politics; however, very little research has been done on the effects of such passive journalism on audiences. This study tests effects of active adjudication versus “he said/she said” journalism on a variety of outcomes, finding that adjudication can correct factual beliefs, increase perceived news quality, satisfy perceived informational needs, and increase the likelihood of future news use. However, for readers who were less interested in the issues under dispute, adjudication also reduced epistemic political efficacy, which is confidence in one's ability to find the truth in politics.  相似文献
