Transformations actuelles des loisirs sportifs : Extension des pratiques adolescentes et apparition d'une offre hybride de loisirs
No full textNotre étude s’est passée en deux temps: une partie quantitative dont le souci a été de réaliser un constat statistique sur la nature et le sens de la participation au loisir sportif d’un échantillon large d’individus de l’académie d’Aix-Marseille. Une partie qualitative où une approche statistique et ethnographique a été réalisée à partir d’une activité de loisir caractéristique des pratiques hybrides récemment apparues dans le secteur marchand du loisir: les parcs aventure. Nous définissons les pratiques hybrides comme des activités développées par le secteur marchand se situant entre une offre instituée classique et la pratique libre. En basant leurs arguments de séduction sur la vente d’un espace naturel sécurisé et domestiqué où les sensations et l’expérience partagée sont mises en avant, le secteur des pratiques hybrides connaît un engouement de plus en plus important. Force est de constater que l’offre proposée dans cette activité est en phase avec les motifs les plus avancées par l’échantillon de sportifs interrogés lors de notre enquête quantitative. L’enquête qualitative sur les motifs qui poussent les individus à fréquenter les pratiques hybrides confirme la place dominante des valeurs de sociabilité et de jeu aux limites dans ce loisir sportif. Les observations outillées et l’analyse des discours des participants permettent de mettre à jour la suprématie d’une expérience combinant sensations, défi et partage. Cette recherche d’expérience aux multiples facettes nous semble en rupture avec les modèles sportifs traditionnels. Ces derniers ont souvent des significations plus univoques, plus tranchées. Axés principalement sur la performance, les repères fédéraux peuvent paraître en décalage avec ce qui motive les individus à pratiquer une activité physique et sportive. Ainsi, à la lumière de nos résultats, il est cohérent de constater une baisse du taux de pratique instituée. Cette baisse serait à interpréter comme un signal de décalage entre l’offre des uns et la recherche des autres. Si les motifs dominants les plus mis en avant se basent sur une recherche combinant sociabilité, performance et expérience émotionnelle, il est normal de voir régresser quantitativement le nombre d’adhérents aux structures proposant une offre à la signification univoque.Our study happened in two stages: a quantitative part was to make a statistical statement about the nature and meaning of participation in leisure sports of a large sample of individuals from the Aix –Marseille’s district. A qualitatively or a statistical approach and ethnographic was made from a leisure activity characteristic of hybrid practices recently appeared in the market sector of leisure: adventure parks. We define hybrid as the practical activities developed by the commercial sector ranging from formal sport and informal sport. Basing their arguments on the sale of seduction of a natural area where domesticated and secure feeling and shared experience are put forward, the sector is experiencing a practical hybrid craze increasingly important. It is clear that the offer in this activity is consistent with the reasons advanced by the sample of athletes surveyed in our quantitative survey. The qualitative survey on the reasons that motivate people to attend practices hybrids confirms the dominant values of sociability and play limits in this recreational sport. Equipped observations and analysis of discourse allows participants to update the supremacy of an experiment combining sensations, challenge and sharing. This research experience with many facets seems at odds with the traditional sports models. These meanings are often more unequivocal, more trenches. Focused primarily on performance, benchmarks may seem Federal sync with what motivates people to engage in physical activity and sports. Thus, in light of our results, it is consistent to find a lower rate of established practice. This decrease is interpreted as a signal of mismatch between supplies of both the research of others. If the most dominant reasons put forward are based on research combining social skills, performance and emotional experience, it is normal to see decline quantitatively the membership structures to offering a single meaning
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
