Orchids have fascinated humans since ancient times. Not only the particular morphology of their flowers and hypogean organs, but also their reproductive biology have inspired myths, legends and popular traditions in many cultures, all around the world. Despite these facts, their representations on ancient artefacts have never been described in the scientific literature. No clear data exist for Eastern culture, and in Western countries, the first certain representations of orchids in art date back to the XV-XVI century CE. This paper documents different identifications of orchids on Roman monuments changing the common belief that these plants first appeared in art more recently. Floral elements of Cephalanthera spp., Spiranthes spiralis (L.) Chevall, of Orchis tridentata Scop., and of other orchids were observed in different architectonical elements (cornices and ceilings) throughout the Roman period, and in the external frieze of the Ara Pacis monument (I century CE). These representations seem to refer to a symbolism of fertility and sexuality, and their absence in medieval time can be explained only considering religion influences. 相似文献

There is an urgent need to address the grand sustainability challenges of our time, and to explore new and more responsible ways of operating, researching, and innovating that enable society to respond to these challenges. The emergent Responsible Research and Innovation (RRI) policy agenda can act as a catalyst towards the development of new and more responsible research and innovation efforts. Inevitably, higher education needs to be closely attuned to this need and agenda, by preparing students to engage in RRI efforts. This paper makes a first step towards guiding the embedding of RRI within higher education. It does so by bringing together academic knowledge with phronesis or practical knowledge about what should be done in an ethical, political, and practical sense. It draws on a literature review and on the reflective practices of partners in the European Commission funded project EnRRICH (Enhancing Responsible Research and Innovation through Curricula in Higher Education), as well as on interviews and case studies gathered as part of the project. The paper suggests elements, especially design principles and a competence framework, for (re)designing curricula and pedagogies to equip higher education students to be and to become responsible actors, researchers, and innovators in a complex world, and to address grand sustainability challenges. In addition, this paper proposes that contemporary higher education teaching and learning policies and strategies, especially those promoting neoliberal agendas and marketized practices, need to adopt a more responsible and responsive ethos to foster the renewal of higher education in times of systemic dysfunction. 相似文献

In this article we discuss processes of internal differentiation that have characterised European higher education systems in the last 50 years. We argue that these processes have gone through two main stages and in two different directions, each of which is showing its limits in the long run. Therefore, we expect a third stage of differentiation, which will be both internal to individual higher education institutions and multi‐dimensional concerning functions performed. In the first stage (1960–1970s) the main objective was to create a vocational track, without having to profoundly modify traditional academic institutions. In the second stage (mid‐1990s) the main objective was to differentiate between the more and the less competitive universities as regards the amount of financial and symbolic resources provided to them. However, large comprehensive universities are containers of smaller units whose performance may vary widely. Moreover, research is just one of the several functions that modern universities perform. The final section of the article provides some empirical evidence from United Kingdom universities to support the hypothesis of a third stage of differentiation. 相似文献

Abstract Press reviews of Hou Hsiao‐Hsien’s films appeared in a range of European magazines at a time when Hou’s films were hardly, if at all, available for watching in European cinemas. This essay asks what, in this context, may have been the reviews’ function. By way of an examination of a representative sample of these texts, I argue that, far from negotiating a relationship between, on the one hand, the producers, distributors and exhibitors of Hou’s films and, on the other hand, Hou’s European public, reviews of Hou’s films served to mediate the gradual and capillary instillation of new modes of viewing films. Reaching Europe very sparingly at a time when European cinemas had finally capitulated to the increasingly aggressive marketing strategies of distributors of Hollywood produce, the construction of Hou Hsiao‐Hsien as an auteur became available for the ‘educational’ realignment needed in order to sell Hollywood cinema better, not in spite of, but because of, the negligible European circulation of Hou Hsiao‐Hsien’s films. 相似文献

IntroductionIntensive physical activity causes functional and metabolic changes in the athlete’s organism. The study aimed to verify the common national available reference intervals (RIs) for common inflammatory and screening coagulation tests in a population of healthy young female athletes.Materials and methodsOne hundred and twenty-one female athletes (age range: 16–34), from various sports disciplines (water polo, handball, volleyball, football, basketball), were included in the study. All participants completed the international physical activity short-form questionnaire. Blood samples were collected between 8–10 am, after an overnight fast, before any physical activity. Reference intervals were determined according to Clinical & Laboratory Standards Institute EP28-A3C Guidelines.ResultsCalculated RIs for white blood cell count (WBC), prothrombin time (PT), and activated partial thromboplastin time (APTT) ratio were in accordance with the common national RIs. Calculated RI for C-reactive protein (CRP) was lower (< 2.9 mg/L) than the proposed cut-off for a healthy population (< 5.0 mg/L). Reference interval for fibrinogen was higher (1.9–4.4 g/L), than the available RIs (1.8–3.5 g/L). D-dimer cut-off value was set at 852 µg/L fibrinogen equivalent units (FEU), higher than the proposed 500 µg/L FEU for venous thromboembolism (VTE) exclusion.ConclusionsThe applicability of the available RIs for WBC count, PT, and APTT-ratio was confirmed. However, RIs for CRP and fibrinogen differed significantly than the available common national RIs for the healthy non-athletes’ population. A higher cut-off for D-dimers should be extensively verified before implementation for VTE diagnosis exclusion in a group of healthy young female athletes. 相似文献

Surveys of scientists' communication behaviours were carried out in a variety of institutions engaged in life science research within the former Soviet Union (FSU). The surveys followed the methodology developed by Garvey and Griffith and used in a variety of studies of information flows in various disciplines within the United States.1 The outcome was a contemporary overview of communication practices which showed, as expected, the devastating effects of the current economic plight of the FSU. It also reveals contrasts between the academy-institute structure of the FSU and more entrepreneurial independent university structure of the West. An extremely important result was the discovery of the extent and ingenuity of cooperative relationships with western scientists to sustain continuing scientific work in the FSU. These were initiated under perestroyka and are now proving essential. The present findings are being used, as a practical matter, to guide and information VINITI policy in furnishing information services to the FSU. 相似文献
