Skills acquisition and personality development during a voluntary social year: a comparison of four different fields of social work
No full textVoluntary work is regarded as a learning environment which facilitates character development and skills acquisition in adolescents. Based on a sample of young adults who completed a year of voluntary work in the social sector, this study investigates whether a volunteer service is accompanied by personality development, networking opportunities as well as amplified cognitive, social, and personal competencies. It is further investigated to what extent the potential for learning and personality development is shaped by the field of activity in which subjects are involved. To this end, this study analyzes retrospective self-ratings of volunteers. The findings indicate that voluntary work is linked to a variety of positively evaluated developmental changes regarding personality and skills. Moreover, the results reveal pronounced differences between different fields of activity. Four domains within the non-profit sector are described and analyzed, with each domain relating to a distinct horizon of experience and unique learning opportunity. These four domains are care and ministration, ambulance and rescue service, education and culture, and sport and exercise
The Influence of Dynamic Yoga Styles on Spinal Flexibility
No full textObjective: Dynamic yoga styles like Ashtanga-Yoga are assumed to have - apart from positive psychophysical health benefits a positive effect on spinal flexibility. The relevant studies reviewed on this topic shared limitations concerning inconsistent measurements of spinal flexibility. Furthermore, only few studies have focused on dynamic yoga styles. Using a non-invasive instrument we assessed the impact of a dynamic yoga-lesson on spinal flexibility comparing it with other health-related kinds of training like strength and machine cardio training. Method: A randomised study (pre-post design) with one intervention yoga group (n = 20), one control group cardio training (n = 21) and a second control group strength-training with machines (n = 21) was conducted. Results: A significant improvement of the spinal flexibility caused by a dynamic yoga session could be found. Mere was only a small impact of the cardio exercises on spinal flexibility and no effect of the strength training. Age, weight or sex did not have any influence on the results. Conclusion: The positive health benefits of dynamic yoga on spinal flexibility confirm earlier studies on this topic. However, there are limitations to our findings as the study was restricted to one single yoga lesson. Therefore, further studies should focus on dynamic yoga's long-term effects in order to evaluate its relevance for health promotion measures
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
