This paper draws on research commissioned to investigate the regional innovation system of Wales on green innovation, focusing on the renewable energy sub-sectors of wind, solar and biomass. It shows how many innovative firms operate within regional networks, cooperating and interacting not only with other firms such as suppliers, customers and competitors, but also with research and technology resource organizations, innovation support agencies, venture capital funds, and local and regional government bodies. The paper argues that within the region there is the presence of various renewable energy production platforms, usually based on core technologies (wind, solar, biomass, marine, etc.) at different levels of development. They involve a mix of established energy utilities and new sustainable energy businesses that are positioned at different levels within the renewable energy supply chain. The research shows that the regional government is playing an important role in supporting the renewable energy industry; nevertheless, more needs to be done to facilitate planning control, provide skills and create new demands for renewable energy that will further foster business growth and further strengthen the existing manufacturing base and innovation in Wales. The paper identifies some weaknesses in the Welsh energy innovation system, not least that energy is not a devolved responsibility and it argues that there is some scope for the Welsh Assembly Government to further investigate gaps within the green innovation supply chain and act on strengthening regional capabilities within the industry but also to support and investigate further opportunities for inward investment.  相似文献

2003年12月贵州人民出版社出版发行的《辛亥革命老人刘莘园遗稿》,其中《联语十则》之第八则有“功在定黔,罪在定黔,乱世为人真不易;朝言革命,暮言革命,先生结局竞如斯”这样一副挽联,根据有关文史资料所述,结合《遗稿》中的作者观点,以及联语中的错字来分析,可知该挽联并非刘莘园作品。  相似文献

A new method for determining the maximum firing temperature of ceramics and burnt clay is presented. The technique relies on measuring the magnetic susceptibility on a step-wise re-fired sample. The validity of the method has been tested by determining firing temperatures of two sets of clay samples fired at temperatures ranging from 400 to 1000 °C. Aliquots of the same samples have been studied petrographically by optical microscopy on thin sections and analyzed by powder X-ray diffraction in order to monitor structural and mineralogical changes as a function of temperature. The method is demonstrated on samples from four geographically widely different sites and it is applied to a larger set of ceramics of Late (ca. AD 900–AD 1450) and Inca (ca. AD 1480–AD 1532) periods from the Northwestern Argentine region, dating to a limited period of time prior to the fall of the Inca Empire. The method is shown to be a powerful tool in revealing archaeological information about the change in firing technologies in the pre-Hispanic societies in the Andean area through time.  相似文献

This paper reviews the concept of Regional Innovation Systems with particular attention on the labour market dimension. It argues that the labour force as a repository of skills and knowledge plays a key role in generating knowledge flows within Regional Innovation Systems. Then, by reference to a number of important dimensions characterizing innovation, five regions from northern Europe are contrasted. In light of research undertaken by the authors the paper highlights the problems associated with a regional system that may hamper innovation and it shows that Regional Innovation Systems can be underdeveloped by being too dependent on public support. Accordingly a combination of public and private governance at the regional level to promote systemic innovation is advocated. The paper also shows how the Regional Innovation Systems can evolve and how regions can become increasingly developmental knowledge laboratories influencing labour market conditions.  相似文献

Abstract: In summer 2006, Professor Ghazi‐Walid Falah, a political geographer and editor‐in‐chief of the journal Arab World Geographer, was arrested by Israeli police after taking photographs of rural landscapes in Northern Galilee. Falah was subsequently held for 23 days, incommunicado, and without charge. An international campaign to “Free Ghazi” was launched by his family, friends and colleagues, largely over academic listservs and other media. Utilizing social network analysis and contextualizing the campaign within structures of telecommunications technologies, the purpose of this paper is to assess the various factors that contributed to the campaign's coalescence, its rapid development, and its global reach.  相似文献

The objective of this paper is to obtain several poverty reduction effects by using multipliers based on social accounting matrices. Expressions relating them to Foster, Greer and Thorbecke poverty measures were derived, and two simulations were carried out for the Spanish region of Extremadura. In the first, we posited a per capita transfer equivalent to certain social policy instruments already existing in this region. Structural path analysis is also used to determine the paths by which poverty reduction effects are transmitted. In the second, we calculate the minimum government expenditure in transfers needed to reduce the regional poverty indices to the national values. The results confirmed that the main feature of poverty in Extremadura is incidence.  相似文献

The use of surgical techniques in ancient Egyptian medicine has only been suggested indirectly through ancient medical texts and iconography, and there is no evidence of amputation as a means of therapeutic medical treatment. This paper presents four cases of amputation from the archaeological site of Dayr al‐Barshā, Egypt. Two of the cases (dated to the First Intermediate and Middle Kingdom periods, respectively) are from individuals that display bilateral amputations of the feet, one through the metatarso‐phalangeal joints, the other a transmetatarsal amputation. The exact reason for the amputation, perhaps from trauma or disease, is unknown. The particular healing patterns of the distal ends of the amputations suggest these individuals used foot binding or prosthetic devices. Another case represents a healed amputation of the left ulna near the elbow, dated to the Old Kingdom. The final case represents a perimortem amputation of the distal end of the right humerus. The exact date of this individual is unknown, but most likely pertains to the Old Kingdom or First Intermediate period. This individual seems to have suffered a traumatic incident shortly before death, sustaining many fractures, including a butterfly fracture on the right humerus. Several cut marks were identified on top of the butterfly fracture, indicating amputation of the arm at this point. All four cases support the hypothesis that the ancient Egyptians did use amputation as a therapeutic medical treatment for particular diseases or trauma.
