This article assesses the impact of armed conflict on the drinking water service of Basrah from 1978 to 2013 through an ‘urban warfare ecology’ lens in order to draw out the implications for relief programming and relevance to urban studies. It interprets an extensive range of unpublished literature through a frame that incorporates the accumulation of direct and indirect impacts upon the hardware, consumables and people upon which urban services rely. The analysis attributes a step‐wise decline in service quality to the lack of water treatment chemicals, lack of spare parts, and, primarily, an extended ‘brain‐drain’ of qualified water service staff. The service is found to have been vulnerable to dependence upon foreign parts and people, ‘vicious cycles’ of impact, and the politics of aid and of reconstruction. It follows that practitioners and donors eschew ideas of relief–rehabilitation–development (RRD) for an appreciation of the needs particular to complex urban warfare biospheres, where armed conflict and sanctions permeate all aspects of service provision through altered biological and social processes. The urban warfare ecology lens is found to be a useful complement to ‘infrastructural warfare’ research, suggesting the study of protracted armed conflict upon all aspects of urban life be both deepened technically and broadened to other cases.  相似文献

This article draws on investigations of worker response to two factory closures to develop recent discussions around mobilization theory. With many shared characteristics between the factories, both located in the garment manufacturing sector, and with similar workforces and union organization, certain key distinguishing features between the two provide insights into why worker protest became effectively mobilized and sustained in one case but failed to materialize in the other. The findings point to the value of assigning greater weight in studies of worker mobilization to the impact of prior existing social structures within a population, and the interaction between that population, its leaders and wider society.  相似文献

Even though there is a worldwide consensus as to the necessity of an audit of annual financial statements for public companies, there is divergence of views as to the review of interim financial statements. While some jurisdictions make it mandatory (e.g., Australia, France, United States), others allow the review without requiring it (e.g., Canada, United Kingdom). Using a sample of companies listed in Canada, we examine the costs associated with these reviews and the benefits they generate in terms of improvement in the quality of interim financial statements for the years 2004 and 2005. Controlling for the decision to purchase the reviews, we find that audit fees are 18 percent higher for firms with interim reviews and, contrary to many regulators' assumption, we find no evidence that this cost increase is proportionally higher for smaller firms. Regarding the benefits of interim reviews, we find no significant association between either accruals‐ or nonaccruals‐based measures of earnings management and the fact that the interim statements are reviewed by the auditor, neither in the interim reports nor in those of the fourth quarter. The results suggest that auditors' involvement with interim reports may not be as effective as previously thought at controlling the quality of interim financial statements.  相似文献

This paper investigates changes in factors bearing on technology adoption decisions in small manufacturing firms. It is hypothesized that, as a firm's experience with technology increases and its technological capabilities grow, the decision process is gradually modified and puts more weight on those factors which are more closely related to the true potential of the technology. An empirical study shows the more innovative firms to have an outward orientation dominated by clients and suppliers, and to pay more attention to the added flexibility brought about by new technology. It is also shown that functional groups within the company play a more important role in the decision-making process.  相似文献

Abstract

Little systematic research has investigated differences in expressed attitude as a function of the manner in which probability information is communicated to a decision maker. The purpose of this paper is to investigate differences in expressed attitude when insurance coverage is introduced in a known-risk situation (the probability of loss is known), an uncertain situation (there is no prior information on the probability of loss) or an ambiguous (the information provided is vague). The experiments reported in this paper have been developed and tested in the classroom with undergraduate students. Unlike the vast majority of previous work dealing with lotteries and laboratory gambles, this study examine the behavior of people when facing a purchase decision on a well-known consumer good, i.e. a bottle of wine. The comparative results provide some evidence on the risk-taking behavior of consumers for small losses. Within an insurance context, people prefer the more familiar option of a known-risk situation and contrary to expectations, the results do not provide support to ambiguity aversion but to ambiguity seeking.  相似文献

This article presents the intellectual structure and 25‐year author cocitation analysis of the journal Business Strategy and the Environment. The findings show that Business Strategy and the Environment is an emerging, well‐established journal in its field. The journal needs a core set of authors who are actively engaged in the production and certification of knowledge; further, it consists of a number of loosely linked research team contributors, each with its own areas of interest. The existence of these research teams is a sign of strength that characterizes the journal as it strives to foster a community of unified scholars whose published works advance our understanding of business strategic decisions and behavior with regard to the natural environment. This study is useful for contributors, readers, and editorial board members who form the journal's community of knowledge creation and certification.  相似文献

Abstract: In this paper we propose that historically generated institutions and persistent pattern of human capital formation condition the emergent systems of innovation in Africa. These factors determine the development path of the region. We advance the notion of dynamic and non‐dynamic systems of innovation, the latter describing the African condition. We combine the strands of literature on institutions and their persistence in shaping development with evolutionary theory and systems of innovation. Evidence is presented on the colonial origins of skewed schooling enrolment, at variance with the industrialization objective of modern economies. Employing simple statistical tests, the persistence of initial human capital (school enrolment) reflects in the significant correlation among the three levels of schooling enrolments, and correlation of enrolment in 1970 with per capita income in 2000, a periodicity of some three decades. This outcome is consistent with the literature on countries at early stages of development. Path‐dependency is partially proved even though we did not attempt to investigate all variables making up the system of innovation. This is a first tentative attempt to explore long‐run development in Africa within the systems of innovation framework.  相似文献

In the present paper, we propose an extension of Spengler's (1950) analysis of successive oligopolies, to study the effects of entry in the downstream and upstream markets. Free entry is analyzed using replica economies à la Debreu and Scarf (1963) . We find that free entry may have different effects in the upstream and in the downstream market. Namely, the usual convergence of the price to the corresponding marginal cost only occurs in the downstream market.  相似文献

DOES SAMPLE DESIGN MATTER FOR POVERTY RATE COMPARISONS?   总被引:1,自引:1,他引:0  
Poverty comparisons—an increasingly important starting-point for welfare policy analysis-are almost always based on household surveys. Therefore they require that one be able to distinguish underlying differences in the populations being compared from sampling variation: standard errors must be calculated. This has typically been done assuming that the household surveys are simple random samples. However, household surveys are more complex than this. We show that taking into account sampling design has a major effect on estimated standard errors for well-known poverty measures. In our samples they increase by around one-half. We also show that making only a partial correction for sample design (taking into account clustering, but not stratification, whether explicit or implicit) can be as misleading as not taking any account of sampling design at all.  相似文献
