This study, an historical survey of medical journals in Louisiana before the outbreak of the Civil War in 1861, revealed that nine journals made an appearance during the period covered-all of them published in New Orleans. Of these, two were French language journals published by a French medical society. The others were all published by individuals rather than by professional societies. Medical practices, interests, and problems of the times were clearly reflected on the pages of the journals. It is evident that medical journalism reached a high plane in the era before the Civil War. Of the nine periodicals, only one emerged as a permanent publication after the War.  相似文献

The history of nursing education in America is briefly told, with the growth of education in institutions of higher learning emphasized. Two trends in nursing education are paralleled by similar developments in nursing literature. The growth of scholarship in nursing is also noted. It is pointed out that nursing is a discipline in its own right, and that training for leadership is required. Continuing education programs are mentioned, together with the increase in nursing literature. Integrated libraries for the health sciences are recommended.  相似文献

Conclusions Palestinian teachers at the pre-collegiate level who participate in the CEEPAT programme will, it is hoped, learn to place new emphasis on enhancement of their students' analytical skills and discourage an identification of knowledge with memorisation. For their part, Palestinian professors who have been trained to teach in the programme will presumably constitute a growing reservoir of talent which may be expected to raise the quality of Palestinian university education. Plans are now under way to give all Palestinians teaching under the auspices of CEEPAT an opportunity to attend an annual, three-week winter seminar in Gaza and/or a summer seminar in the United States, both of which will focus on issues of pedagogy and methodology. Such professors can be expected to pass on their new understanding of teaching via discussion to their colleagues and to their university students, thereby spreading an important pedagogical method to other segments of the Palestinian... community. 7 CEEPAT clearly has the potential to make a significant contribution to the elevation of educational standards in Palestine at a time of major historical change.In Palestine, higher education of quality is obviously a very serious business. It is understood that it underlies any possibility of individual betterment, economic development, or the evolution of an independent Palestinian state. If ever the Israeli occupation is completely terminated and the present financial crisis of the universities is solved, Palestinian university and post-baccalaureate training may reasonably be expected to become fully competitive on an international scale.  相似文献

The purpose of the study was to identify the pattern of publication about women and AIDS in scientific journals. Bradford zones were identified in each of six databases. The study determined that journal scatter for this subset of AIDS literature differed from the scatter in the general literature; further, the information indexed in the six electronic sources demonstrated little overlap. Consequently, key journal and newsletter titles identified by this study should form the core of any collection focusing on women and AIDS. The assurance of quality patient care management demands that librarians consult multiple resources for information retrieval that can assist health care providers, patients, and caregivers to enhance quality of life as well as to provide optimum care.  相似文献
