Health care system in the Czeck Republic
No full textThis article reviews the health care system in the Czech Republic. It is aimed to point out the different matters in contrast to the Italian system. It summarizes the historical changes regarding the health care after the "fall of communism" in 1989 and the split of Czechoslovakia (1993) and basic organizational questions; particular consideration is devoted to the pharmaceutical care, hospitals accreditation, a responsibility of the physician and free and informed consent. The health care system in the Czech Republic has underwent many changes during the last years and its further transformation reflecting social requests can be expected
5-Phenyluridine trihydrate
No full textThe title compound (systematic name: 2,4-dihydroxy-5phenyl-1-beta-D-ribofuranosylpyrimidine trihydrate), crystallized as the trihydrate, C15H16N2O6 center dot 3H(2)O, stabilized by hydrogen bonds to the uracil O atoms. Two statistically disordered water solvent molecules occupy channels along the a axis; the site occupancy factors are ca 0.6 and 0.4. The heterocyclic base is almost planar and is oriented anti with respect to the puckered sugar moiety. The sugar ring adopts a conformation intermediate between twist and envelope

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Substance use and knowledge among Italian High School students.
No full textThis study was aimed for evaluation of Italian students' attitudes to addictive substances, their knowledge and personal experience, and their awareness about the risks. The research was realized among high school students from Marche region in the Central Italy in the year 2006; the study group was randomly chosen from all schools in the region. 4118 appropriately completed questionnaires returned. The statistic processing was carried out by
using chi-square test for two qualitative variables. 29.9 % of the students have tried drugs; 36.4 % of the
interviewed reckon alcohol, tobacco and antidepressants
for drugs. A relationship between the use of licit and illicit addictive substances and a correlation between the use of illicit substances and the use of liquors and tobacco
in family was found. The students, who drink frequently,
smoke regularly and use drugs, believe that the drugs create
dependence only if overused; only a quarter of them
classify themselves as drug addicts.
The study indicates a lack of information on the drugs among the young people. It emerges that the young people do not sufficiently know the risk of the dependence. A change of the preventive strategies should be considered
