Linkage between moderate wins consumption and well-being: analysis of Italian consumers by regions over time
No full textLINKAGE BETWEEN MODERATE WINE CONSUMPTION AND WELL-BEING: ANALYSIS OF ITALIAN CONSUMERS BY REGIONS OVER TIME Introduction: Italy has an old experience in wine production and consumption. Indeed, it is one of the most famous European and worldwide producer together with France and Spain. The country’s share on the world market is 20% and 33% on the European one (Romano & Natilli, 2009). As for wine consumption, it depends on different factors including geographical features (Villanueva et al., 2017). Wine characteristics, consumers’ preferences and consumption habits as well as wine culture vary territorially. The origin of the wine has a crucial importance for consumers’ decisions, sometimes they are willing even to travel for distanced areas with the aim to taste particular products of concrete wine producing regions (Antonazzo et al., 2015). Wine culture of the region somehow defines also consumers’ perception how the consumption of wine affects on their health and wellbeing. For instance, French policies advocate the restriction of wine consumption that indirectly influence on consumers’ perception of negative impact of wine on their health (Vecchio et al., 2017). However, firstly the importance has to be given to consumption frequency. Usually, heavy wine consumers decrease consumption in later years for health purposes (Stockley et al., 2017). Though, wine is a healthy product when it is consumed moderately; its impact on health depends on wine characteristics and attributes as well, whether it is red or white, variety of grapes and other variables (Artero et al., 2015). Aim: The purpose of this work is to investigate and prove the connection among wine consumption, health and well-being. We intend to analyze also how this link varies over time and territory on the example of Italian 21 regions, so to compare these regions in two different years, 2010 and 2017, based on different variables. Methodology: In order to meet the paper objectives, we analyze data of the Italian National Institute of Statistics – ISTAT (2018 a and b) that gathers the statistical surveys. The research is based on the following variables: (1) Moderate wine consumption; (2) Health composite index; (3) Social relationship composite index; (4) Subjective wellbeing composite index. We have used the cluster analysis and a set of statistical unsupervised methods for classifying the units into homogeneous groups. More precisely, we have used fuzzy clustering instead of classical method that does not allow units to belong to more clusters simultaneously. As for cluster validity, we decided to use different cluster validity methods to have different meters of comparison to evaluate our procedure. They are as follows: (1) Xie-Beni index – XBI (Xie & Beni, 1991); (2) the modified partition coefficient – MPC (Dave, 1996) and fuzzy silhouette index – FSIL (Campello and Hruschka, 2006). Results: With regard of the quantity of clusters, all three indices show the same result of three clusters as optimal solution. Nevertheless, they have different consistent of regions in 2010 and 2017 years (fig. 1 a and b). However, it is possible to make comparisons, taking into account for each year the link between the centroids describing the different clusters and the Italian values in the variables considered. In this way, we can characterize the 3 clusters: Cluster 1 as the one with the best values, Cluster 2 as the one with the worst values and Cluster 3 as the one with peculiar values compared to the national data, in both years considered. a – Year 2010 b – Year 2017 Figure 1 – Wine consumption, hedonism style and health: clusters composition; membership degrees; centroids. We can observe the so-called North-South gap, with the Northern and Central Regions with values higher than those of the Southern ones in all indicators (except in the Health composite index, in which the differences are less marked). The moderate wine consumption shows almost similar values in 2010 and 2017. Conclusion: In general, both the 2010 and 2017 analysis in all regions of the country confirm the existence of a relationship between moderate wine consumption and composite indicators of health, social relations and subjective wellbeing. Results showed North-South gap meaning the strong difference between the different areas of the country. In fact, northern and middle regions entered in a Cluster 1, described as having best values while in southern Italy the situation is worse than average of the country so they entered in second Cluster with the worst values. After cluster analysis. It is possible to conclude that the overall situation in the country is improved over time since Cluster 1 increased from 10 to 12 regions with Sardegna and Abruzzo in addition and Cluster 2 decreased from 8 to 5 regions from 2010 to 2017
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
