This paper explores surviving documentation and what it reveals about the underlying social structure and relations in a historic time and place. The mid-nineteenth century is chosen as a period prior to modern bureaucracies so that documents are not found in defining filing systems. Some six hundred documents are studied individually and characterized collectively. They are examined not to tell a story, however, but for evidence of their creation and maintenance and of their physical types, functional characteristics, and relations between authors and recipients. The study reveals the fruitfulness of such an orientation to documents, which complements traditional historical uses that emphasize document content. 相似文献

Conclusions On the basis of these findings, I suggest that the structure and organisation of the field of Hungarian economics under state socialism should be described as a case of partitioned bureaucracy.9 The compromise between research economists and the political elite in the New Course era between 1953 and 195510 survived the post-1956 reaction in so far as political economy, with its predominantly legitimatory and ideological functions, remained partitioned from the other sectors in the field through the remainder of the state-socialist period. This secured considerable protection both for Marxist-Leninist political economy—which faced the destabilising effects of exposure to the findings of serious empirical research—and for the other sectors, which were professionally oriented and earnestly interested in the pursuit of unbiased empirical research, free from stifling agitprop interference. Our data concerning the reputational control of the field reflects only one, although very important, aspect of this partitioning. Another and much plainer aspect is that, from the early 1960s, the Agitation and Propaganda Department of the Central Committee no longer exercised control over the field, except in the political economy sector.The proposition about the mechanism paradigm should not be taken seriously as a statement of a Kuhnian type of intellectual organisation of Hungarian economics, with reform economics at its hard theoretical core. But it should certainly be taken seriously as a reflection of the sociopolitical structure which emerged and developed from the mid-1950s onwards. Neither the politicians nor the economists saw as necessary or even contemplated the integration of Hungarian economic research with Western mainstream economic thought. In exchange for the professional expertise and socio-economic intelligence necessary for the exercise of power, Hungary's state-socialist political class offered their economists relative autonomy and freedom from interference. The price the economists had to pay was partly to refrain from openly and systematically challenging the beliefs perpetuated by the political economy of socialism, and partly to accept in their research the paramountcy of policy orientation. But this burden they assumed willingly since it made them the only group within Hungary's academic intelligentsia—indeed, the only group in Hungarian society outside the political class—with the privilege of being coopted to the institutions with power over some restricted domains of policymaking. After 1989, especially under the conservative Antall government, this proved less than advantageous.11 Although the benevolence of many critics is open to question, it could greatly benefit the field if the economists' expulsion from contemporary politics went hand in hand with provision of the material, intellectual and institutional conditions for a new approach where a fundamentally scientific orientation is paramount. 相似文献

Controversy concerning the issue of homosexual rights and practiceshas intensified in Britain over the last decade. Despite thisincrease in intensity, however, the question of mass publicopinion in relation to homosexual rights and practices has receivedalmost no empirical investigation. In an effort to remedy thissituation, this article focuses on both the role of respondents'gender as well as their perceptions concerning the gender ofparticipants in a homosexual relationship (both sexes versusgay men) in distinguishing their attitudes toward the publicacceptance of homosexuals and the adoption rights of lesbiansand gay men. Using nationally representative data from the BritishSocial Attitudes Surveys, we found that, whereas both respondents'gender and the gender of participants in a homosexual relationshipdemonstrated a significant influence on attitudes toward thepublic acceptance of homosexuals, they were unrelated to theadoption rights of lesbians or gay men. Even in relation tothe public acceptance of homosexuals, however, gender was notthe only, or even the most important, attribute in distinguishingindividual opinion in this instance. Other stronger and moreconsistent influences were education, age, and attitudes towardeither pre-marital or extra-marital sexual relations. The implicationsof these findings for both policy makers and homosexual activistsare discussed. 相似文献

One of the highest priorities in today's hospitals is the provision of quality care to patients. The medical librarian has an increased responsibility to furnish quality information to the medical staff. Traditional methods of reference service continue to work well, but it is increasingly important for librarians to become more directly involved in hospital quality assurance (QA) activities. Occurrence screening is one system of QA where the librarian can make a difference. 相似文献
