We present an overview of previous research results on the molecular phylogenetic analyses in Agaricales and its higher ranks (Agaricomycetes/Agaricomycotina/Basidiomycota) along with the most recent treatments of taxonomic systems in these taxa. Establishing phylogenetic hypotheses using DNA sequences, from which an understanding of the natural evolutionary relationships amongst clades may be derived, requires a robust dataset. It has been recognized that single-gene phylogenies may not truly represent organismal phylogenies, but the concordant phylogenetic genealogies from multiple-gene datasets can resolve this problem. The genes commonly used in mushroom phylogenetic research are summarized. 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
With the plethora of health sites on the Internet, it is sometimes hard to know where to start. This is a basic list of health sites that either cover a subject area comprehensively, or are good general sites to lead to more specific information. Most of these sites include both full-text information as well as links to many other sites on the World-Wide Web. Included are medical, nursing, dental, alternative health, consumer health, organization, and government sites. 相似文献
