The history of the establishment of the scientific research station on Laurie Island, South Orkney Islands, is recounted. Its founding by the Scottish National Antarctic (Scotia) Expedition (1902–04) and the subsequent operation by Argentina resulted in it becoming the first all‐year‐round permanently‐staffed research facility in Antarctica. The networks of government and non‐government personnel involved in the rivalry between British and Scottish interests and aspirations and the transfer of the Laurie Island facility from the Scottish expedition to Argentine government control are investigated. The narrative is set against the background of the centennial celebrations of that transfer. 相似文献

While the prevalence of smoking has declined in the UK in recent years, class differentials in smoking behaviour have become more marked and smoking is increasingly recognised as a causal factor in inequalities in health. Health education initiatives to support both smoking cessation and to teach children about the health risks of smoking remain key initiatives in reducing health inequalities. However, teaching children about the risks of smoking and the impact of parental smoking on their health is not straightforward for children from backgrounds who are more likely to encounter smoking at home and in their local communities. These children have to reconcile the key messages taught at school and reinforced in smoking cessation campaigns with the knowledge that their parents and other family members smoke. In this article we consider how children from smoking homes make sense of these education and health campaigns as observed by their parents, and the impact that this has on both parental smoking and relationships within the home. The article thus seeks to challenge assumptions about the delivery of health education and the need to acknowledge family diversity. 相似文献

The Canadian inner city is currently marked by diversity and dynamism. One way to approach this diversity is through photography. A visual approach was used to capture the simultaneous upgrading, decline/revitalization, decline and stability within the changing landscapes of Southwest Montréal, Canada's original industrial heartland. 相似文献

For half of a century, models of nonrational behavior have grown in popularity for explaining the behavior of administrative organizations. However, models of nonrational behavior are notoriously difficult to test because nonrational behavior is often difficult to separate from fully rational behavior. Recent research has suggested that particular types of nonrational processes should produce "punctuated" equilibria rather than "instantaneous" equilibria. In these nonrational processes, a decision maker underresponds to changes for a long period of time. Once pressure for change becomes overwhelming, the decision maker adopts a radical change. This is called "punctuation." The key to identifying this type of nonrationality of a process's rationality is the comparative success of fitting the observed behavior to "punctuated" rather than "instantaneous" equilibria.
True, Jones, and Baumgartner (1999 ) developed a method for comparing the distribution of decision outputs as a strategy for assessing the relative degree of "punctuation" in the decision processes. By assessing the kurtosis (or "peakedness") of the distribution of decision outputs, one can get a sense of the excess (compared with a standard, normal distribution) of low and high rates of change–a sign of punctuated equilibrium.
This article extends these recent developments by adapting the method to a comparative kurtosis framework. The results suggest that bureaucracy in K–12 schools serves to reduce (rather than amplify) the punctuations in budgeting processes. The article concludes with a discussion of the potential extension of the empirical results and modifications to the testing procedure. 相似文献

Geoffrey Stokes 《Australian journal of political science》2004,39(1):5-22
Arguments for reshaping political agendas invariably begin from an appraisal of past errors and achievements. Paul Kelly's notion of the ‘Australian Settlement’ attempts such a task. Kelly identifies a particular ideological and institutional tradition in Australian politics that dominated much of the twentieth century and that is now deemed to have broken down. This article accepts that the notion of a Settlement provides certain insights into the evolution of Australian political thought. Nonetheless, the paper takes issue with the specific content of Kelly's version of the ‘Australian Settlement’ and indicates how it may be reformulated. It argues that, to the extent that we can speak of a ‘Settlement’ in Australia, it was one reached on a wider range of key conflicts or cleavages than those to which Kelly refers. 相似文献

In this paper, we expand upon a prior study [Surovell, T.A., Brantingham, P.J., 2007. A note on the use of temporal frequency distributions in studies of prehistoric demography. Journal of Archaeological Science 34, 1868–1877.] that explored the problem of taphonomic bias. Taphonomic bias refers to the tendency for younger things to be over-represented relative to older things in the archaeological record due to the operation of destructive processes like erosion and weathering. Using a database of radiocarbon dated volcanic deposits from Bryson, R.U., Bryson, R.A., Ruter, A. [2006. A calibrated radiocarbon database of late Quaternary volcanic eruptions. Earth Discussions 1, 123–124.], we develop an empirical model of taphonomic bias. In contrast to our prior study in which we modeled taphonomic bias as an exponential function wherein the likelihood of site loss remains constant through time, we argue that the probability of site destruction actually decreases with site age. We further demonstrate how this model can be used to correct temporal frequency distributions and extract demographic histories. We illustrate this approach using databases of radiocarbon dates from rockshelter and open-air sites in the Bighorn Basin, Wyoming, USA, and mammoths and humans in Siberia, Russia. 相似文献

This study examines the potential socio-spatial impacts of a new series of marine protected areas (MPAs) on fishers in Moorea, French Polynesia. The establishment of the MPAs is contextualized within recent and historical processes of economic development and theories of women in development and gender, culture and development. Seventy adults from three neighborhoods in Moorea were interviewed. Analysis of the data provides new information about the characteristics of fishing in Moorea. Unlike most fishing cultures and communities throughout the Pacific Islands, men and women in Moorea have similar, as opposed to segregated, spatial patterns of fishing activities and fishing methods. The study also points out the potential negative impacts of the MPAs on both men and women, particularly younger and lower-income fishers. 相似文献

The Loch of Clickimin, Shetland, is well known for its broch and associated monuments supposedly of the Bronze and Iron Ages, although the former date is disputed. Pollen, diatom and sedimentological investigations permit fresh insights into the landscape and economic impacts of those who constructed the monuments, reveal that the environs of the site experienced environmental change from Neolithic times onward and provide the first Holocene radiocarbon dates from the immediate locality. The broch-building period witnessed a continuation of pre-existing pastoral husbandry for which heather burning may have exacerbated the natural spread of blanket peat. Initially, no evidence was adduced for local arable activity in the present investigation, and this was thought to be consistent possibly with the low numbers of excavated querns and the absence of cereal macrofossil finds when compared with other Shetland broch sites. The application of ‘rapid scanning’ techniques, however, led to the discovery of a consistent cereal-type pollen representation from Bronze Age times onwards. The discrepancies between the palaeoenvironmental evidence and the environmental and palaeoeconomic inferences made by the excavator of the site are explored. Evidence is presented that both supports and contradicts previous assumptions surrounding an important archaeological site. 相似文献

This paper examines the impact of information technology on urban spatial structure in the Chicago region. Urban scientists are challenged to understand in what ways information technology has influenced the distribution of urban economic activities: concentration or dispersion. Using data collected in the Chicago region, orientation of establishments toward the center is tested to separate the impact of locational features of centers from the impact of information technology. The result reveals that information technology has attraction as well as spillover effect on urban spatial structure and thus concentration rather than dispersion is dominant at a local scale in the Chicago region. It was found, however, that center‐orientedness varies depending on the sector. 相似文献
