A cross-sectional analysis of ex-smokers and characteristics associated with quitting smoking: The Polish Norwegian Study (PONS)
No full textTobacco smoking remains a number one preventable risk factor of premature death worldwide. Findings of recent research show concurrent trends of lung cancer deaths in males and females in Europe. Although lung cancer death rates are consistently decreasing in male population, in women an upward trend is observed. The burden of tobacco-related harm can be prevented by smoking cessation. The main goal of this analysis is to identify the crucial correlates of successful smoking cessation in the middle-aged Polish population. The data came from 13 172 survey participants south-eastern part of Poland as part of the PONS cohort study established in 2010. A total of 6998 records of those who were either ex-smokers or current smokers at baseline were analyzed. We applied logistic regression and adjusted for sociodemographic covariates and health determinants. Characteristics related to being an ex-smoker as opposed to a current smoker included: older age [men: odds ratio (OR)=1.03, 95% confidence interval (CI)=1.01-1.05; women: OR=1.05, 95% CI=1.03-1.07], being married or living together, having secondary (OR=1.51, 95% CI=1.14-1.99) or higher (OR=2.30, 95% CI=1.75-3.18) education (women), full-time employment (men), alcohol consumer (women), being overweight (men: OR=2.85, 95% CI=2.26-3.59; women: OR=1.60, 95% CI=1.36-1.87) or obese (men: OR=3.47, 95% CI=2.67-4.51; women: OR=2.99, 95% CI=2.45-3.65), having normal fasting glucose and cholesterol blood level without any treatment (women), assessing their own health highly (9-10, on the scale from 1 to 10) and having at least one accompanying chronic disease (women, OR=1.25, 95% CI=1.07-1.45). These findings provide valuable information on characteristics of ex-smokers as well as behavioral and sociodemographic predictors of successful cessation. Such data expand our knowledge and can be used to design a more comprehensive and targeted group-specific tobacco control policy focused on increasing the number of ex-smokers
Alcohol accounts for a high proportion of premature mortality in central and eastern Europe
No full textBackground: There is a west-east mortality gradient in Europe, more pronounced in men. The objective of this article was to quantify the contribution of alcohol use to the gap in premature adult mortality between three old (France, Sweden and United Kingdom) and four new (Czech Republic, Hungary, Lithuania and Poland) European Union (EU) member states for the year 2002. Russia was added as an external comparator. Methods: Exposure data were taken from surveys and per capita consumption records from the World Health Organization (WHO) Global Alcohol Database. Mortality data were taken from the WHO databank. The risk relationships were taken from published meta-analyses and from the WHO Comparative Risk Assessment project. Alcohol exposure and relative risk information was combined to derive alcohol-attributable fractions for relevant causes of premature mortality. Results: Alcohol consumption was responsible for 14.6% of all premature adult mortality in the eight countries, 17.3% in men and 8.0% in women. This proportion was clearly higher in the new EU member states and Russia compared with the comparison countries from the old EU. For men, Russia with 29.0 alcohol attributable premature deaths per 10 000 population had a more than 10-fold higher rate compared with Sweden (2.7 deaths/10 000). For women, the ratio between Hungary (5.0 alcohol-attributable deaths/10 000) and Russia (4.7 deaths/10 000) compared with Sweden (0.5 deaths/10 000) was almost as high, but the rates were much lower. The Czech Republic and Poland showed proportionally less alcohol-attributable premature mortality than the other new EU member states or Russia for both genders, which, however, was still higher than in any of the old EU member states. Conclusions: Alcohol is a strong contributor to the health gap between western and central and eastern Europe, with both average volume of consumption and patterns of drinking contributing to burden of disease and injury. Alcohol also contributes substantially to male-female differences in mortality and life expectancy. However, there are feasible and cost-effective measures to reduce alcohol-related burden that should be implemented in central and eastern Europe. © The Author 2007; all rights reserved
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
