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
Mindfulness and psychosomatic well-being among firefighters: a mediational model
No full textAs a consequence of the exposure to potentially traumatic events, firefighters are at high risk to develop traumatic stress reactions (Wagner et al., 2010) and psychosomatic effects, such as emotional strain and feelings of hyper-arousal (Beaton & Murphy, 1993). But, as demonstrated by the Job Demands-Resources model (JD-R; Bakker et al., 2003; Demerouti et al., 2001), every occupation has both job demands and job resources, that reduce job demands and the related costs. In this view, in addition to job demands and their associated negative effects, firefighters have also psychological resources at their disposal. An example is represented by mindfulness, that is the ability to pay attention to and to be aware of the current experience (Brown & Ryan, 2003; Kabat-Zinn, 1990). It has been widely demonstrated that mindfulness may influence levels of physic-physical well-being (Kabat-Zinn, 1990; Shapiro et al., 1998).
This study aims to test a new process underlying the negative relationship between mindfulness and psychosomatic malaise. In particular, we proposed that intrusion predicts symptoms of general dysphoria in response to mindfulness.
The sample consisted of 255 Italian firefighters (both professional and volunteer). Self-report measures were used to assess mindfulness (MAAS; Brown & Ryan, 2003), psychosomatic symptoms (GHQ-12; Goldberg & Williams, 1988) and post-traumatic manifestations (STSS-It; Setti & Argentero, 2012).
Data were analyzed using structural equation modelling. Mindfulness did not directly influence general dysphoria whereas mediation analyses revealed its meaningful indirect effect via intrusion (standardized indirect effect = -.041**). According to our results, mindfulness leads to reduced symptoms of general dysphoria through low levels of intrusive thoughts.
From a theoretical perspective, to our knowledge this is one of the first studies focused on the protective role of mindfulness against the risk of developing psychosomatic malaise via post-traumatic manifestations. From a practical point of view, our results suggest the importance to implement interventions based on the reduction of post-traumatic symptoms, on the one hand, and on the enhancement of mindfulness, on the other hand. Through these strategies, people could learn to regulate distressing thoughts and feelings that occur in response to stressful events
The Impact of Age Discrimination on Engagement of Older Workers: the Buffering Role of Proactive Personality
No full textPurpose
The workforce in most industrialized countries is aging: this ongoing demographic change provides new challenges for the organization management. In particular, recent reports show an increase in perceived age discrimination, that is the prejudice by one age group toward other age groups: this differential treatment can be unintentional or deliberate, unconscious or explicit. In the workplace, age discrimination is often manifested in such organizational practices as limiting older workers from job responsibilities or restricting access to career development opportunities. Despite the importance of this topic, there has been relatively little research on age discrimination and its negative impact on both worker and organization. Therefore, the purpose of the present study is to test the effect of age discrimination on engagement of older workers. Drawing on the social exchange framework and in particular on the norm of reciprocity, we hypothesize that when employees feel treated unfairly they will respond by reducing their engagement, that is a broad measure of employee’s reciprocity with the organization. The second aim of the study is examine the presence of moderating factors that can mitigate this negative relationship. Specifically, proactive personality is the tendency to affect environmental changes: proactive individuals take actions to influence their environment, identify opportunities and show initiatives. Therefore, age discrimination should have a differential relationship with engagement for older workers with low or high level of proactive personality.
Design
Data were collected from 120 workers over 55 years in an insurance company in Italy. Hierarchical regression analysis was performed in order to test direct and moderated effects.
Results
Results show that age discrimination is negatively related to engagement for older workers (main effect). Moreover, there is a moderating effect of proactive personality on the relationship age discrimination-engagement: older workers reported lower levels of engagement, are those with high age discrimination and low proactive personality (interaction effect).
Practical Implications
Organizations should take into consideration that age discrimination leads to negative effects on work attitudes for older employees: the fact that proactive personality can buffer these consequences suggests to develop this characteristic, for example focusing on activities such as mentoring, group processes and citizenship behaviours
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
