Post-war reconstruction. Participatory approaches to rebuilding the damaged villages of Lebanon: a case study of al-Burjain 总被引:1,自引:0,他引:1
This paper focuses on the reconstruction of war-damaged villages in Lebanon destroyed during the civil war (1975–1991). It presents a holistic approach that considers the complexity of socio-economic, cultural and organisational issues involved in shaping the built environment, in contrast to conventional top–down approaches, which concentrate largely on physical aspects. Therefore, the paper attempts to gain an insight into the socio-cultural conditions of the communities prior to disaster and into the specific situations, which emerged after the destruction of the villages. This will be illustrated by means of a detailed case study of one Lebanese village—namely al Burjain. It develops an understanding of the conditions of the people, their needs and perceptions about rebuilding the village and derives the specific and general principles that should guide the reconstruction process. The paper is based on fieldwork, which employs a qualitative approach that offers flexibility and suits the practical conditions in the field. This allows dynamic discussions with the community under study and permits better understanding of the local conditions. The developmental approach proposed for reconstruction presents principles and good practices appropriate for rebuilding the villages in Lebanon in particular and in similar reconstruction contexts in general. 相似文献

Methods are suggested for improving the coverage accuracy of intervals for predicting future values of a random variable drawn from a sampled distribution. It is shown that properties of solutions to such problems may be quite unexpected. For example, the bootstrap and the jackknife perform very poorly when used to calibrate coverage, although the jackknife estimator of the true coverage is virtually unbiased. A version of the smoothed bootstrap can be employed for successful calibration, however. Interpolation among adjacent order statistics can also be an effective way of calibrating, although even there the results are unexpected. In particular, whereas the coverage error can be reduced from O ( n -1 ) to orders O ( n -2 ) and O ( n -3 ) (where n denotes the sample size) by interpolating among two and three order statistics respectively, the next two orders of reduction require interpolation among five and eight order statistics respectively. 相似文献

Spatiotemporal prediction for log-Gaussian Cox processes 总被引:1,自引:0,他引:1

Space–time point pattern data have become more widely available as a result of technological developments in areas such as geographic information systems. We describe a flexible class of space–time point processes. Our models are Cox processes whose stochastic intensity is a space–time Ornstein–Uhlenbeck process. We develop moment-based methods of parameter estimation, show how to predict the underlying intensity by using a Markov chain Monte Carlo approach and illustrate the performance of our methods on a synthetic data set. 相似文献

理学作为一种思想体系受到朝廷的推崇,并作为科举考试的组成部分。在20世纪,对理学的看法发生了分歧。有人认为理学是智识与科学进步的障碍,中国要想走向现代化就必须摆脱理学。关于中国在12世纪后进入长时期停滞的看法,历史学界一般都不赞成了,但读者的这种看法还比较强烈。对于中国历史的一些基本特征的认识需要重新检验,比如中国文化不是只有一个起源;中国并非与外界隔离并拒绝外界影响;中国的政治体制不是绝对独裁;中国文化并没有一个纯正的“正统”或“道统”(orthodox);中国人并非没有自主的完整实体的“自我”观念。学者在实际研究中往往把中国当作一个实体民族或一个连续不断的文明体,这种观念并不太准确,实际是误解了China的原意。 相似文献

所谓“西方”,本身是一个历史的建构。欧洲特定的文化背景,历史上一系列的文化及社会运动,对历史思想和历史书写都产生了重大影响,使得西方史学具有了一定程度上的独特性,譬如强调进步和发展等等。然而这种独特性并不是一连串独一无二的特征,也不意味着西方历史著作的方式在所有方面都优于其他方式。归根到底,正是不同体系之间的冲突,尤其是不同“力量”之间的动态平衡,才构成西方历史思想和历史书写的特点。 相似文献

This article is based on a study which examined hypotheses about Japanese marketing using a matched sample of British companies and their major Japanese competitors. Japanese subsidiaries in Britain were shown to be much more marketing-oriented, more responsive to strategic opportunities, and more single-minded in their pursuit of market share. Organizationally, there were few differences between the two groups. The Japanese subsidiaries, however, were more inclined to use product or market-based divisions and continuous, informal planning and control procedures. The result is that managerial focus and responsibility are centred upon overall product-market rather than financial or production performance, with continuous feedback facilitating rapid adaptation and implementation of marketing plans and strategy. 相似文献

There is consensus that the effective implementation of cross-functional teams is critical to new product success. However, such teams face particular challenges because of well-documented barriers between functions. Furthermore, there is little evidence-based guidance for practitioners on how to achieve effective cross-functional teamwork. In order to address this gap, the literature on cross-functional teamwork was analysed to identify critical success factors. Using a heuristic team effectiveness model, these were categorized into six groups: task design, group composition, organizational context, internal processes, external processes and group psychosocial traits. Recent theory on group effectiveness has increasingly recognized the significance of a supportive organizational context, and this is particularly pertinent for cross-functional teams. Key success factors include strategic alignment between functions, a climate supportive of teamwork and team-based accountability. The findings are integrated into a diagnostic model which is intended to be of practical benefit to people designing, leading and facilitating cross-functional new product development teams. 相似文献

The theory of the firm seeks to explain the existence and boundaries of the firm in relation to the market. Since the pioneering work of Coase (The nature of the firm. Economica , 4 , 386–405, 1937), economics has developed a whole family of theories that focus on the ability of firms to economize on certain costs of using markets. More recently, researchers in strategic management have published several theories of the firm that have tended to emphasize the benefits of incorporation rather than the costs of using the market. Although researchers in the strategy profession have tentatively labeled their work as 'moving towards' a strategic theory of the firm, economists have been very critical of existing approaches. This paper seeks to begin 'arriving' at a strategic theory of the firm by addressing these criticisms and offering an integration of the strategic and economic perspectives within an institutional framework. The paper concludes with future directions for research in the theory of the firm. 相似文献

The debate continues over whether prescribed quantities or unit pricing offers the best method to enable consumers to make value-for-money comparisons. In theory, the 'informed' consumer should benefit from being given unit-price information to identify optimum purchases; in practice, however, it would appear that many consumers do not use the data. Although unit pricing can reduce the level of confusion caused by large product ranges and large numbers of unique size–price combinations, results of a survey of over 1000 people showed that: 31% of the sample did not understand how unit pricing was meant to help them compare products; 35% could not be bothered to look at unit prices and 28% stated that unit pricing was too difficult to use. Those least likely to look at unit prices are women, the least educated and consumers aged 18–34. The research investigated why consumers do not use unit-price information and found: some consumers do not possess the cognitive ability to process the information and feel unit pricing is too complicated to use; some products are not comparable, which makes unit prices misleading; many shops do not provide unit-price information; unit-price information was felt unnecessary when evaluating products with few or no alternative sizes or brands; unit-price comparisons take too much time; consumers use simpler strategies for getting value for money, e.g. volume discount heuristic, own brands, special offers, x% free, reward points, etc. The paper explores policy and retailer implications for unit pricing and examines recommendations for government. 相似文献
