Advances in the phylogenesis of Agaricales and its higher ranks and strategies for establishing phylogenetic hypotheses

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.     

On the problem of determining a citation index of publications by Kazakh scientists

This paper discusses the evaluation of scientific activity with the help of some scientometric indices, in particular, a citation index. The information massif of the bibliographic database of citations to domestic publications of Kazakh authors is statistically described.     

Key issues of the development of the information infrastructure and information support of innovation activities

We consider some issues of the development of the national information infrastructure in the field of innovation, including a national system of accounting for the results of scientific and technical activities (RSTA) and a national new-generation research computer network (NNGRCN). The current state of the national system of scientific and technical information and its resources for information support of innovation processes are analyzed. In the context of further development of the Commonwealth of Independent States (CIS), we propose a Conception of scientific and technical support for programs and projects of NIS member-states in the field of innovation, making it possible to incorporate the existing innovation-oriented information resources into a joint distributed integrated information system as well as to create new information resources and technologies.

Expanding rural primary care training by employing information technologies: the need for participation by medical reference librarians

The use of rural sites to train badly needed primary care providers requires access to sophisticated medical information not traditionally available outside of academic health centers. Medical reference librarians can play a key role in the development of primary care training sites in rural settings. Electronic information technologies, with proactive support from medical reference librarians, can provide current and detailed information without concern for distance from the health science center library. This paper discusses recent developments in technology, describes current challenges to the application of this technology in rural settings, and provides policy recommendations for medical reference librarians to enhance rural primary care training.     

Science at Harvard University, 1846-47: a case study of the character and functions of written documents

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.
