Still photography is an important medium for visually communicating — and scrutinising — the power of elected representatives. However, it has been severely restricted by parliaments. Surprisingly, the photographs taken by press photographers have been viewed as a larger threat to parliamentary dignity than other seemingly more powerful media, such as television. This article analyses parliaments’ “extraordinary sensitivity to photography” 1 by conducting a comparative, historical examination of press photography in five national parliaments — Australia, Canada, New Zealand, the United Kingdom and the United States. The article discusses historical milestones in media access for each of these parliaments, but focuses particularly upon the unusual case of the Australian Parliament and its rules on still photography. The author draws upon interviews conducted with Australian press photographers, as well as an analysis of primary material — including parliamentary guidelines on media access, photographs, newspaper reports, parliamentary debates, inquiry reports and submissions.  相似文献

Ernest Cole’s photographs reveal the contradictions and paradoxes of apartheid South Africa. At a very young age, and with little formal instruction Cole instinctively produced a significant documentary photo-book titled House of Bondage (1967). This article makes a close reading of some of Ernest Cole’s photographs in relation to the historical circumstances of apartheid and how they can be perceived through the lens of hindsight in postapartheid South Africa. The work offers a potent argument for the power of perception to uncover overlooked moments of the period. As an African, Cole’s photographs construct a narrative of apartheid from the position of an “invisible” black insider. In so doing, they tellingly reveal how he used the system of apartheid to his own advantage in his photographic practice. His photographs ask us to consider his modus operandi and the courage it took to make them at that time, offering the opportunity to behold moments that cut across gaps of space and time.  相似文献

The status of international agricultural research as a global public good (GPG) has been widely accepted since the Green Revolution of the 1960s and 1970s. While the term was not used at the time of its creation, the Consultative Group on International Agricultural Research (CGIAR) system that evolved at that time has been described as a 'prime example of the promise, performance and perils of an international approach to providing GPGs'. Contemporary literature on international agricultural research as a GPG tends to support this view and focuses on how to operationalize the concept. This paper adopts a different starting point and questions this conceptualization of the CGIAR and its outputs. It questions the appropriateness of such a 'neutral' concept to a system born of the imperatives of Cold War geopolitics, and shaped by a history of attempts to secure its relevance in a changing world. This paper draws on a multi-sited, ethnographic study of a research effort highlighted by the CGIAR as an exemplar of GPG-oriented research. Behind the ubiquitous language of GPGs, 'partnership' and 'consensus', however, new forms of exclusion and restriction are emerging within everyday practice, reproducing North-South inequalities and undermining the ability of these programmes to respond to the needs of projected beneficiaries.  相似文献

Sixteen percent of children 6-11 years of age were classified as overweight in 1999-2002, four times the percentage in 1965. Although poverty has traditionally been associated with underweight as a result of poor diet, researchers have recently pointed to a paradox in the U.S., which is that low income and obesity can coexist in the same population. This paper first examines whether income is linked to overweight in school-age children. Second, it explores whether food programs such as the Food Stamp Program, the National School Lunch Program, and the School Breakfast Program are associated with overweight among children in different income groups. The data come from the nationally representative 1997 Panel Study of Income Dynamics Child Development Supplement. No evidence either that poor children are more likely to be overweight or that food programs contribute to overweight among poor children was found.  相似文献
