We apply GIS techniques to analyze a carefully selected database of 93 Early Neolithic sites in the Iberian Peninsula. This allows us to study the spatial dynamics of the Neolithic transition in Iberia. We study how the Neolithic was introduced into the peninsula in order to test the hypothesis that the Neolithic was introduced almost simultaneously from two sources: one at the northeast (via the Mediterranean coast) and another one at the south (possibly from Northern Africa). We also analyze how the expansion of the Neolithic transition took place within the Iberian Peninsula and measure local rates of spread in order to identify regions with fast and slow rates (such as the slowdown at the Cantabrian coast). In addition, we attempt to reproduce the main results obtained from the GIS analysis by applying reaction–dispersal models to the expansion of the Neolithic transition in the Iberian Peninsula. We conclude that a model with two sources is a reasonable assumption that agrees better with the archaeological data available at present than a model with a single source.  相似文献

This article describes the conditions for the development of four industrial clusters and the mechanisms of their integration in the regional economy. The case studies are the aerospace and apparel clusters in Montreal, and the agri‐food and marine science and technology clusters in the Lower St. Lawrence region. Clusters are defined as arrangements of businesses, government actors, public authorities, and local intermediary organizations in a local area. However, the study shows that clusters are based on actors and processes operating at different scales, from the local to the global. It also shows the importance of the sectoral leadership acknowledged by the different stakeholders.  相似文献

Everyday knowledge – body knowledge – knowledge of experience – specialized knowledge: Acquisition, assessment and the orientation of logic concerning cultures of knowledge. – The essay explores changes in the understanding, legitimisation, and practice of midwifery. It was one of the earliest professional activities for women. During the eighteenth century a new culture of expertise emphasized theoretical knowledge and adherence to medical disciplines over the empirical practice gained by women. This early phase of professionalisation, with its hierarchies and preferred use of medically accredited knowledge, was not, however, solely divided along gender lines. Female professionalism was not just supplanted by male academic medicalisation. New ways of attaining and assessing knowledge, a different perception of how it is organised, and above all, social change created new patterns of understanding. This process achieved a new professional ethos. In pursuing the issue of gender, various examples are chosen to illustrate how changes in scientific knowledge and its relevant application are mediated. The construct of scientific knowledge and how it is used reflects gender relations and power structures. There is not only competition between female and male perceptions of knowledge, but also male stereotyping of female knowledge, in particular male notions of what kind of knowledge is necessary and how this is perceived by women. Karen Offen used the term ‘knowledge wars’ to describe how a monopoly of scientific expertise and relevant knowledge works within the professions.  相似文献

As deportations from the United States rose to unprecedented levels, a nationwide immigration enforcement program Secure Communities helped identify deportable noncitizens under arrest in county jails. Examining county‐level variation in deportation activity between 2008 and 2013, this paper contributes to immigration policy research by examining how county officials in some locations facilitated exceptionally restrictive deportation outcomes while others exercised the discretion to turn noncitizens over for deportation sparingly. Consistent with a hypothesized “tiered influence” relationship, but contrary to a “racial threat” hypothesis, Hispanic concentration predicts the highest levels of exercised discretion where Hispanic concentration is neither too small nor too large. Noncitizens under arrest seem to have benefited from above‐average Hispanic concentrations, except in counties where Hispanics exceed about 40 percent of the population.  相似文献

At the European level, several strategic documents concerned with spatial and urban development have been published during the last decades. While these documents are essential to communicate European ideas and objectives, they are often regarded least influential in practice due to their abstract nature, legally non-binding status and lack of allocated resources. Though these limitations apply to the EU Urban Agenda, this recently published policy paper introduces partnerships as a new implementation tool. The partnerships can be regarded as innovative in two respects: On the one hand, they involve new actors, most importantly cities, in European policy debates. On the other hand, they ensure the anchorage of the Urban Agenda with a broad range of actors at various spatial scales without challenging its legally non-binding status. The Urban Agenda can thus be understood as another example of the move towards soft European spatial planning and urban development. This article investigates the notion of partnership as a soft planning and governance tool within the Urban Agenda. Moreover, based on expert interviews, it presents early opinions and expectations of actors involved in the development of the Urban Agenda and the partnerships on affordable housing.  相似文献

上古史是中国近代历史学的重要研究对象,有关上古神话的研究更引起了广泛关注。吕思勉利用文献考据、社会从低级到高级的发展规律及“统属思维”塑造的“同质人类群体”的概念,对上古神话进行清理和重构,形成了区别于传统的新解释,并尝试以此取代传统思想中有关上古神话的“旧常识”。这种新旧知识迭代背后隐藏着吕思勉以“统属性思维”取代“关联性思维”的研究理路,是近代新史学打造学科话语体系的尝试,也彰显出历史学家普遍面对的“当下主义”的困境,以及这种困境对于历史知识迭代的意义。  相似文献

The term “millets” is used to identify several genera of grasses (Poaceae), most of which belong to the subfamily Panicoideae. Millets are one of the major food sources in arid and semi-arid areas of the world and they have been important crops in the prehistory of Africa and Eurasia. In this paper, we discuss phytoliths and starch grains from two of the less studied major millets (Pennisetum glaucum and Sorghum bicolor) as well as from some small millet species that are not normally considered of much importance (so-called forgotten millets: Digitaria ciliaris, Echinochloa colona, Echinochloa frumentacea, Brachiaria ramosa, Setaria pumila and Setaria verticillata). The preliminary results of this study on phytolith morphology, both at single and joined (silica skeletons) morphotypes, and starch grains show great potentials for the identification of different genus or species on the basis of microremains.  相似文献

Historical films made by neuroscientists have shown up in several countries during past years. Although originally supposed to have been lost, we recently found a collection of films produced between 1909 and 1940 by Rudolf Magnus (1873–1927), professor of pharmacology (Utrecht) and his student Gysbertus Rademaker (1887–1957), professor of physiology (1928, succeeding Willem Einthoven) and neurology (1945, both in Leiden). Both collections deal with the physiology of body posture by the equilibrium of reflex musculature contractions for which experimental studies were done with animals (labyrinthectomies, cerebellectomies, and brainstem sections) and observations on patients. The films demonstrate the results of these studies. Moreover, there are films with babies showing tonic neck reflexes and moving images capturing adults with cerebellar symptoms following cerebellectomies for tumors and several other conditions. Magnus’ studies resulted in his well-known Körperstellung (1924, “Body Posture”) and Rademaker’s research in his Das Stehen (1931, “Standing”). The films probably had an educative and scientific purpose. Magnus demonstrated his films at congresses, including the Eighth International Congress of Physiologists (Vienna, 1910) and Rademaker screened his moving images at meetings of the Amsterdam Neurologists Society (at several occasions as reflected in the Winkler-Monakow correspondence and the Nederlands Tijdschrift voor Geneeskunde). Next to these purposes, the films were used to analyze movement and a series of images from the films were published in articles and books. The films are important historical sources that provide a portrait of the pre-World War II era in neuroscience, partly answering questions on how physicians dealt with patients and researchers with their laboratory animals. Moreover, the films confirm that cinematography was an important scientific tool in neuroscience research.  相似文献

This paper reviews a tourist planning experience developed for the Couto Mixto in 2007–2008. The Couto Mixto is a small territory of three hamlets situated in Galicia (Spain) and bordering Portugal that, until the end of the 19th century, used to be a virtually independent state of 25 km2. This tourism planning process is compared and contrasted with the well‐described Action Research (AR) approach. The paper begins by providing the conceptual foundations of tourism planning which were used as a framework for the research. Then, the tourism planning experience is introduced in detail, focussing on the results of the interviews conducted to identify the tourism resources of the area. Therefore, 23 resources were inventoried and further audited to determine their various degrees of potential for the purposes of tourism planning. Previous AR experiences and the tourism planning initiative developed for the Couto Mixto share a common objective to facilitate change in communities in trouble. However, the case‐study tourism planning experience was not fully compliant with genuine AR in several respects. We conclude by recommending AR as a worthy approach for tourism planning as a way to effectively put the local community in focus.  相似文献
