In 1918, the U.S. Public Health Service (PHS) told American parents that "it is no longer possible for you to choose whether your child will learn about sex or not." According to the PHS, most American boys learned about sex from "improper sources" by the age of nine. The "unfortunate effect of these early impressions" had, PHS warned, not only resulted in a gross misunderstanding of sex, but also been a major factor in the spread of venereal disease (The Parents' Part [the U.S. Public Health Service, 1918], p. 5). To counter and correct this miseducation, PHS joined with the Young Men's Christian Association (YMCA) to create a sex education program aimed at adolescent boys. Officially launched in the spring of 1919, the "Keeping Fit" campaign provides a unique insight into the federal government's attempt to medicalize and regulate American sexuality through the forum of public health.  相似文献

From studies of ‘panoptic’ CCTV surveillance to accounts of undercover police officers, it is often mooted that visibility and invisibility are central to the policing of public space. However, there has been no comprehensive and critical assessment of this axiom. Drawing on the practices of a variety of policing providers and regulators, and the work of geographers, criminologists and other social scientists, this paper examines how and why visibility underpins the policing of public space. We begin by considering the ways in which policing bodies and technologies seek to render themselves selectively visible and invisible in the landscape. The paper then moves on to explore the ways in which policing agents attempt to make ‘incongruous’ bodies, behaviours and signs variously visible and invisible in public space. We then offer a sympathetic critique of these accounts, arguing that more attention is needed in understanding: (i) how other senses such as touch, smell and sound are socially constructed as in and out‐of‐place and ‘policed’ accordingly; and (ii) how the policing of undesirable bodies and practices is not simply about quantitative crime reduction, but conducted through qualitative, embodied performance. The paper concludes by pinpointing key areas for future research.  相似文献

The purpose of this paper is to review and discuss the relationship between government publications and academic studies of flood management in Bangladesh. The paper reviews these literatures while also emphasizing the assumptions, objectives and national issues that have influenced modern flood management. This approach aims to engage with the evolving knowledges used to inform and to criticize flood management in one of the most flood-prone nations on earth. The analysis suggests a disconnection between government and academic knowledge, particularly concerning the characterization of government objectives within the academic discourse. The paper is divided into four periods in which the objectives, methods and understandings were fundamentally reoriented, contributing to the current discrepancy between government and academic approaches to flooding and flood management. The paper concludes with discussion of three issues related to the competing assumptions of flood risk management in Bangladesh and raises the issue of growing complexity in relation to hazards management.  相似文献

Over 50 identifications of Tertiary pollen are reviewed. The pollen assemblages indicate rain-forest through most of the Tertiary, but the requisites for pollen preservation are biased towards the wetter climates.

The present day geographical affinities of the botanical groups are largely with taxa of the tropical zone and Australia-wide taxa. There is geographic variation in the fossil pollen assemblages when southeastern Australia is compared with Central Australia and Queensland.

The major changes in the fossil floras coincide with climatic change, indicating the influence of climate on the evolution of plant assemblages. The older phytogeographic concepts are inappropriate for the fossil record, especially when considered in conjunction with palaeoclimates and palaeogeography.

It is unfortunate that palynology has given little information of the evolution of floras in drier climatic regimes, or of the evolution of the eucalypts.  相似文献

This article explores issues of socio‐cultural identity in the north‐western Roman provinces, using all the available archaeobotanical evidence of date (Phoenix dactylifera L.). This fruit does not conform to the general social distribution pattern of other Roman exotic food plant imports in this area, but instead indicates a strong ceremonial connection. Through an in‐depth contextual approach the role of date in both domestic and ceremonial sites is investigated to reach beyond the simple ‘date‐Roman‐ritual’ association. The results suggest strong temporal, spatial and contextual patterning and an overall rare occurrence and selective use of the fruit in certain rituals and mystic cults. Date may have been employed not necessarily as a food, and was probably an affordable luxury for some in their ritual pursuits. As such, date can now be regarded as part of specific ceremonial expressions rather than a standard ingredient of a normative ceremonial or ‘Roman’ identity.  相似文献

The difficult but by no means dysfunctional relationship between President Abraham Lincoln and Congress remains an understudied aspect of Civil War history. Indeed, it is impossible to arrive at a comprehensive or convincing explanation for Union victory until that relationship is limned more precisely. This article contends that U.S. Senator William Pitt Fessenden (1806–69) played a critical mediating role in the wartime Congress. He did so firstly in his capacities as chair of the Senate finance committee and close associate of U.S. Secretary of the Treasury Salmon P. Chase and secondly as a public supporter of executive war powers. Although the influential Maine Republican had serious doubts about the effectiveness of the Lincoln administration, his determination to quash the southern rebellion and considerable powers of self‐restraint enabled him to act as an important and constructive broker between the White House and the fractious Republicans on Capitol Hill.  相似文献
