Sforzo, ricompensa e rottura del contratto psicologico: il ruolo del coinvolgimento lavorativo
No full textDiversi studi hanno mostrato interesse verso la comprensione delle variabili responsa-bili del contratto psicologico. Il presente contributo intende verificare gli effetti che le variabili considerate dal modello dell’Effort-Reward Imbalance (Siegrist, 1996) quali responsabili dello stress hanno sulla rottura del contratto psicologico. Lo studio è stato condotto su 300 lavoratori spagnoli. I risultati mostrano che lo sforzo, la ricompensa e la mancanza di equilibrio tra queste due elementi (E-RI) influenzano la rottura del con-tratto psicologico. Viene infine riscontrato il ruolo moderatore dell’overcommitment fra lo sforzo, l’E-RI e la percezione di rottura del contratto psicologico
Overcoming presenteeism: how can we prevent it?
No full textThe phenomenon of presenteeism (defined as
showing up for work when one is ill) has only
received interest in recent years, with research
suggesting that it might cause more
aggregate productivity loss than absenteeism
(Johns, 2010). Some researchers also founded
that job demands can enhance the propensity
to work of employees who feel sick and their
presenteeism might become a precursor of
exhaustion and depersonalization over time
(Demerouti, 2008). In this regard, job insecurity
has been considered as a factor that might
influence this phenomenon. Starting from
these premises, the main aims of this study
were to examine the relationship between job
insecurity, presenteeism and burnout, and the
factors that might moderate this relationship
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
Psychosocial risk factors and well-being: An application of the Job Demands-Resources model at the Italian justice department
No full textThe general aim of the present study was to identify the factors more associated to health and well-being of workers of an Italian Justice Department, by testing either the health impairment process and the motivational process of the Job Demands-Resources model. A self-report questionnaire was administered to 195 participants working at Justice Department.
The central hypothesis was that job demands would be the most important predictors of ill health, through their relationship with need for recovery, whereas job resources would be the most important predictors of affective commitment, through their relationship with work engagement. Results of a series of SEM analyses supported these dual processes and gained insight about the psychosocial risk factors in order to understand how prevent organizational malfunctioning and promote a good work environment. This means that, in order to understand the processes that are involved in fostering well-being, it is important to take into account both job demands and resources because the increase of job resources promote positive organizational outcomes, and decreases in job demands prevent ill-health
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
