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
Comparison of Life Satisfaction between physical activity levels according to age in Luxembourg: Health Behaviour in School-aged Children survey 2022
No full textBackground: Life satisfaction is a major component of adolescents’ subjective well-being. Physical activity (PA) is associated with the improvement of physical, cognitive, and mental health. Objective: This study aimed to analyse adolescents’ life satisfaction (LS) and levels of PA across age in adolescents from Luxembourg. Method: A representative sample of 7089 adolescents (11-to-18-years-old) took part in the Health Behavior in School Aged Children (HBSC) Luxembourg 2022 survey. LS was measured using Cantril Ladder, levels of PA were determined according to the time spend on and frequency of moderate-vigorous and vigorous PA and classified into: Highly active, Active, Low active and Not active. A two-way ANOVA was performed to analyse differences in the LS mean for PA and age groups. Results: All 11-12y have a better LS than the other age groups in all PA groups (p<0.01). However, Highly Active pupils reported better LS than those Not active, Low Active and Active, in all age groups (p<0.01). Low Active (mean=7.26, CI95%7.10-7.43; mean=6.93 CI95%6.78-7.10) reported worse LS than those who were Active in the 13-14y (mean=7.55, CI95%7.44-7.66; p=0.02) and 15-16y (mean=7.29 CI95%7.18-7.40; p<0.01). Conclusion: PA is a factor associated with better LS in adolescents in Luxembourg in all ages. Furthermore, the study showed that although Highly Active pupils have a higher life satisfaction, being physically active is better than Not being active. This study reinforces the importance of PA to maintain a higher life satisfaction through adolescence in Luxembourg

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
The impact of physical activity on anxiety and depression among adolescents in Luxembourg
Full text linkpeer reviewedBackground: According to the WHO (2019), anxiety and depression are among the leading causes of illness and disability among adolescents. Anxiety disorders are the most common emotional disorder, estimated at 4.6% of 15–19-year-olds experiencing it. Depression is also common, affecting 2.8% of 15–19-year-olds. Both anxiety and depression can importantly affect an adolescent’s life. Having an emotional disorder during adolescence increases the likelihood of having it during adulthood. Physical activity is known to be negatively associated with depression and anxiety (Rebar et al., 2015). However, the extent of this relationship among adolescents in Luxembourg remains unstudied. The present study aims to understand the relationship between anxiety and depression, on the one hand, and physical activity, on the other, in adolescents in Luxembourg.
Methods: This study is based on the 2022 Health Behaviour in School-aged Children Luxembourg survey. A total of 8415 adolescents aged 11 to 18 years old, were included in this study. The Generalised Anxiety Disorder Scale was used in its 2-item form (Kroenke et al., 2007) to measure anxiety, while the WHO-5 Well-Being Index was used for depression (Allgaier et al., 2012; Blom et al., 2012). Based on the time spent on and frequency of moderate-vigorous and vigorous physical activity, adolescents were categorized into highly active, active, low active and inactive. Binary logistic regressions were performed to estimate the predictive power of physical activity on anxiety and depression. The level of statistical significance was .05.
Results: The prevalence of anxiety and depression symptoms in the studied population was 34.6% and 29.5%, respectively. A negative association between the levels of physical activity, on the one hand, and anxiety and depression, on the other, was found. For instance, compared to those who are highly active, the odds of presenting depression symptomatology are OR=1.64 (95CI 1.37-1.97) for those who are active, OR=2.68 (95CI 2.23-3.23) for the low active, and OR=4.35 (95CI 3.42-5.53) for the inactive adolescents. Similar results are found for anxiety.
Conclusion: As the physical activity levels decreased, the likelihood of experiencing depression or anxiety symptoms increased significantly in adolescents in Luxembourg. Those findings corroborate the literature, suggesting that practising physical activity during adolescence has a protective effect on the outcomes of depression and anxiety. As such, physical activity should be encouraged as part of the preventive strategies in order to decrease the prevalence of depression and anxiety in Luxembourg
The impact of bullying in school in pupils’ well-being - comparison in the different types of school in Luxembourg
No full textpeer reviewedA person is considered to be bullied when repeatedly exposed to negative actions of others over time (Olweus, 1996). Adolescents who are bullied more frequently experience negative psychosocial outcomes, such as lower levels of well-being (Halliday et al., 2021). The present study aims to compare the mean levels of well-being within bullying victims/non-victims in the different types of school in Luxembourg. In the (Health Behaviour in School-Aged Children) HBSC Luxembourg study, adolescents were asked how often they have been bullied at school and the WHO-5 Well-Being Index measured subjective well-being. Independent t-tests were performed to compare the mean values of well-being by victims and non-victims of bullying by each school type. Although in Luxembourg, the prevalence of bullying victimization decreased since 2006 (13% in 2006 vs 7% in 2022), in 2022 it varied considerably in the seven different school types, from 1.6% (in ESC-sup) to 13.6% (in VP). Adolescents who had not been bullied exhibited significant higher mean levels of well-being compared to those who had experienced bullying in past two months in most of the school types, the exception being pupils from VP, in which no significant difference was found. As individuals evaluate their own experiences in comparison to others (Festinger, 1954), it is possible that once a pupil is being bullied in a context where many others experience the same situation, this problem might be relativized, while in the context of infrequent bullying, the detriment to one's well-being might be increased

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
