As the educational use of computer mediated communication (CMC) increases there is growing interest among researchers as to social processes evolving within the varied models of group work using Internet, e.g., special interest groups, topical discussion groups, discussion forums attached to virtual courses, and learning communities. In this paper we present a synthetic summary of five studies that explored social climate issues in synchronous and asynchronous online activities in academic courses, focusing on the following questions: Does a social atmosphere develop in online learning discussion groups? What are the different modes of social interaction are manifest in online learning discussion groups? What is the role of the virtual teacher with regards to the social climate in online learning discussion groups? Discussed are the implications of these five studies' on the design of virtual-learning-discussion-groups, and the results for the characterization of teacher moderation functions.

We studied sexual dysfunction (SD) prevalence and lack of sexual activity in 117 women undergoing coronary angiography. SD was consistent with a low (≤26.55) Female Sexual Function Index questionnaire (FSFI) score. The mean age was 61.8 years (range: 40-75 years). SD prevalence was 76.1% (n = 89), and 41 (35.0%) women reported a lack of sexual activity. Regression analyses showed that only age was independently associated with SD (odds ratio 1.088; 95% confidence interval 1.024-1.157; p = .006) and lack of sexual activity (odds ratio 1.144; 95% confidence interval 1.064-1.230; p < .0001), regardless of cardiovascular risk factors, inflammatory biomarkers blood levels, and the number of stenotic coronary arteries.

This chapter deals with the process of giving names to newly discovered microorganisms and assigning names to them that are correctly formed in agreement with the rules of the relevant code of nomenclature: the International Code of Nomenclature of Prokaryotes for the prokaryotes (Archaea and Bacteria, including a small number of cyanobacteria), and the International Code of Nomenclature for algae, fungi, and plants for the microfungi and for most cyanobacteria. In-depth discussions will be devoted to the online databases and handbooks, where updated information can be found about all names with standing in the nomenclature.
