Zipf's rank‐size rule, lognormal distribution, and Gibrat's urban growth models are considered as summarizing fundamental properties of systems of cities. In this article, they are used as statistical benchmarks for comparing the shapes of urban hierarchies and evolutionary trends of seven systems of cities in the world including BRICS, Europe, and United States. In order to provide conclusions that avoid the pitfalls of too small samples or uncontrolled urban definitions, these models are tested on some 20,000 urban units whose geographically significant delineations were harmonized in each country over 50 years between 1960 and 2010. As a result, if the models appear not always statistically valid, their usefulness is confirmed since the observed deviations from empirical data remain limited and can often be interpreted from the geohistorical context of urbanism proper to each world region. Moreover, the article provides new free software which authorizes the reproducibility of our experiments with our data bases as well as with complementary data.  相似文献

Given the significant trading relationships between Canada and the United States, their transnational corporations and their tax authorities share more than a border. However, differences in transfer pricing regulations, tax rates, and regulatory enforcement philosophies have exacerbated many existing risks, and created new risks for executives in these corporations. These risks must be managed proactively, yet attempts at risk management are often incompatible with one tax authority or the other. Assuming that an operational transfer pricing framework is in place, there are several proactive strategies available to mitigate transfer pricing risk and potentially satisfy both tax authorities. An operational framework and proactive strategies, including documentation and advance pricing agreements, are discussed from the Canadian and US perspective, including expert interviews.  相似文献

Hurricanes Katrina and Felix made landfall in 2005 and 2007 on the Gulf Coast of the US and the Atlantic Coast of Nicaragua respectively. Despite many economic, political and cultural differences between these two sites, they share a number of interesting similarities. Their inhabitants are subject to similar modes of racialized Othering and internal colonialism, and both places have vital links with the transnational cultural consciousness that Gilroy referred to as the Black Atlantic. Katrina and Felix also occurred at a time when centralized forms of media are increasingly perceived to be in crisis. This crisis is creating new spaces for the development of alternative ways of knowing, watching and making media. This paper draws on recent literature on decolonization by Mignolo, Escobar, Quijano and others to explore the prospects for decolonizing energies within the new media environment and a context of devastation wrought by neoliberalism and disaster. This research examines disasters in/and the new media environment, and suggests that activists should understand the distinctions between mainstream (or corporate) and alternative media, between top‐down and grassroots media, and between “old” and “new” media, in relational and non‐categorical rather than absolute terms. These media realms should be engaged from an awareness of how they interact with and impact upon one another. This research also suggests that disasters must be understood as ongoing and open‐ended events embedded within historical, social, cultural, economic and political processes and systems. Media, policymaking and emergency management practices that are informed by an awareness of this complex embedding, and which are therefore able to take a long‐term view of the unfolding of disasters, will be best equipped to engage effectively, and in democratically responsive ways, with disasters and in particular with the needs of those populations most vulnerable to their impacts.  相似文献

This article presents the results of the excavation of a residence dated between the second and fourth centuries AD, constructed over the ruins of the South Arabian town of Makaynūn, in central Hadramawt (Yemen). The building yielded a large quantity of material including objects proving contacts between the central Hadramawt and regions located to the north‐east, such as central Oman, the Gulf area and India.  相似文献

This article examines the relationship between the introductionof women Justices of the Peace (JPs) in 1919 and the gendereddevelopment of juvenile courts in England, c. 1910–39.It argues that the campaigns for the appointment of women asJPs and for new methods of dealing with delinquent childrenwere closely connected from 1910 onwards, when the proposalwas first made that ‘suitable’ persons should beappointed to hear ‘suitable’ cases in magistratescourts. Using evidence drawn from government records and othersources, the article examines the interaction of the two campaignsand of feminist and penal reform groups in securing the remodellingof London's juvenile justice system in the Juvenile Courts (Metropolis)Act of 1920. It argues that these arrangements, and similarones adopted elsewhere in England, consciously reflected presumedfamilial and gender roles. It concludes that the replicationof the ‘traditional’ family in the composition ofthe court may have limited the ability of the youth justicesystem to be innovative in its approach to juvenile delinquencyin the period up to 1939. * a.f.logan{at}kent.ac.uk  相似文献

This paper argues that women's everyday practice of sharing fish at Warraber Island (Torres Strait) can be understood as a form of moral transaction. Gift‐fish are shown to be ‘socially entangled’, a fundamental mode of expressing kin relatedness as well as providing an indication of the current state of such relations. Fish distribution is portrayed locally as both an instance of generosity and of obligation, demonstrating a person's desire to engage in socially valued behaviour or correct their past failings. Importantly, I suggest that fish‐giving (and receiving) has a distinctly generational character, carrying different emphases across one's life‐span. The paper reflects on the tensions involved in strategic efforts by women to reconcile their limited capacity to meet expectations from a wide range of kin and neighbours, while affirming idealised visions of communally shared moral values.  相似文献

Abstract. In this paper, we suggest a framework that allows testing simultaneously for temporal heterogeneity, spatial heterogeneity, and spatial autocorrelation in β‐convergence models. Based on a sample of 145 European regions over the 1980–1999 period, we estimate a Seemingly Unrelated Regression Model with spatial regimes and spatial autocorrelation for two sub‐periods: 1980–1989 and 1989–1999. The assumption of temporal independence between the two periods is rejected, and the estimation results point to the presence of spatial error autocorrelation in both sub‐periods and spatial instability in the second sub‐period, indicating the formation of a convergence club between the peripheral regions of the European Union.  相似文献

Globalization and neoliberalism are having significant impacts upon the cleaning industry, as in the drive for greater work “efficiency”. One way in which cleaning companies have sought to increase efficiency is through the introduction of new equipment and forms of work organization. However, such moves appear to be having negative impacts upon cleaners’ bodies, and many report significant work‐related health problems. In light of this, here we explore the bodily consequences of two possible strategies for giving cleaners a healthier workday—increasing variation within cleaners’ current work tasks or allowing them to engage in a broader range of tasks through job enlargement. Drawing upon a literature review performed as part of a recent European Union project concerning the degree of physical strain to which cleaners are exposed during cleaning, a Danish laboratory study focusing on the loads to which cleaners’ shoulder muscles, backs, and hearts were exposed by different cleaning tasks, and a field study investigating the effects of job enlargement in Danish hospitals, we show that cleaning work is characterized by repetitive work for the muscles of the body's upper extremities and by high levels of dynamic and static force upon these muscles, regardless of which modes of cleaning (old or new style of cleaning tools) are used. Equally, monitoring of heart rates and assessment of the psychosocial environment suggest that simply interchanging current cleaning tasks does not provide sufficient variation in cleaners’ work to prevent work‐related musculoskeletal or cardiovascular damage, nor to create a less mentally stressful work environment. Although introducing greater work variation through job enlargement (such as combining cleaning with kitchen and portering tasks) is often presented as an effective way to minimize musculoskeletal and cardiovascular damage, our field study shows that even this does not provide sufficient variation in physical work conditions, although improvement in some cleaners’ mental health was noted. Therefore, we conclude, prevention of musculoskeletal and cardiovascular disorders demands a much more comprehensive strategy of work redesign than that proposed by some employers and government agencies. Whether this is likely, given competitive pressures towards increased outsourcing and privatization, is, of course, the question.  相似文献
