Key for identification of the ladybirds (Coleoptera: Coccinellidae) of European Russia and the Russian Caucasus (native and alien species).

Although ladybirds of European Russia and the Caucasus have been the subject of numerous ecological and faunistic investigations, there is an evident lack of appropriate identification keys. New, original keys to subfamilies, tribes, genera, and species of ladybirds (Coccinellidae) of European Russia and the Russian Caucasus are presented here. The keys include all native species recorded in the region and all introduced alien species. Some species from adjacent regions are added. In total, 113 species are treated and illustrated with line drawings. Photographs of rare and endemic species are provided. Information on the distribution of species within the region under consideration is provided. Chilocorus kuwanae Silvestri, 1909 is recognized as a subjective junior synonym (syn. nov.) of Ch. renipustulatus (Scriba, 1791).

A Survey to Determine Decision-Making Styles of Working Paramedics and Student Paramedics.

OBJECTIVE: Two major processes underlie human decision-making: experiential (intuitive) and rational (conscious) thinking. The predominant thinking process used by working paramedics and student paramedics to make clinical decisions is unknown. METHODS: A survey was administered to ground ambulance paramedics and to primary care paramedic students. The survey included demographic questions and the Rational Experiential Inventory-40, a validated psychometric tool involving 40 questions. Twenty questions evaluated each thinking style: 10 assessed preference and 10 assessed ability to use that style. Responses were provided on a five-point Likert scale, with higher scores indicating higher affinity for the style in question. Analysis included both descriptive statistics and t tests to evaluate differences in thinking style. RESULTS: The response rate was 88.4% (1172/1326). Paramedics (n=904) had a median age of 36 years (IQR 29-42) and most were male (69.5%) and primary or advanced care paramedics (PCP=55.5%; ACP=32.5%). Paramedic students (n=268) had a median age of 23 years (IQR 21-26), most were male (63.1%) and had completed high school (31.7%) or an undergraduate degree (25.4%) prior to paramedic training. Both groups scored their ability to use and favourability toward rational thinking significantly higher than experiential thinking. The mean score for rational thinking was 3.86/5 among paramedics and 3.97/5 among paramedic students (p<0.001). The mean score for experiential thinking was 3.41/5 among paramedics and 3.35/5 among paramedic students (p=0.06). CONCLUSION: Working paramedics and student paramedics prefer and perceive that they have the ability to use rational over experiential thinking. This information adds to our current knowledge on paramedic decision-making and is potentially important for developing continuing education and clinical support tools.

Statistical techniques reported in pathology journals during 1983-1985. Implications for pathology educators.

The increasingly scientific basis of medicine challenges pathology educators to incorporate quantitative skills into a very compressed curriculum. One strategy is to focus training on the statistical techniques pathologists will most commonly encounter in their literature. We identified the reporting of statistical techniques in nearly 5200 original articles published during 1983-1985 in 16 journals important to pathology. Our results suggest that a reader familiar with 12 fundamental statistical concepts can evaluate knowledgeably over 95% of the quantitative findings reported in these journals. With the exception of survival analysis and pharmacologic modeling, these techniques are typically encountered in many introductory statistical texts. In numerous articles, failure to identify the statistical methodology used made it impossible to identify the analytic procedures used and, hence, judge the scientific validity of results.

Spectrum and frequency of use of statistical techniques in psychiatric journals.

Educators in psychiatry face an important challenge in deciding what quantitative skills to teach and where in the educational agenda to teach them. One strategy is to focus the quantitative training of psychiatrists on techniques they need to be effective consumers of their literature. The authors catalogued the statistical methods described in 15 major psychiatric journals during 1983 and 1984. A dozen procedures, typically encountered in intermediate-level statistics courses, accounted for approximately 95% of all the statistical methods reported. Readers of psychiatric journals also routinely encounter multivariate, nonparametric, and categorization techniques. Educators might apply these results in designing exposure to statistical skills for future psychiatrists.
