Leader-member Exchange (LMX) quality and follower well-being: A daily diary study.
Get PDFGuided by Self-determination and Social Exchange theories, we examine how leader-member exchange (LMX) quality impacts follower well-being. Despite LMX relationships being dynamic in nature, the way relationship quality varies over time and its impact on well-being has not been examined in detail. To address this important issue, a daily diary study is reported of employees from a variety of organizations. 158 participants completed a daily diary in the morning and evening for five consecutive workdays (k = 603 observations). Measures included hedonic and eudaimonic well-being, and social and economic LMX exchanges. There was a significant variation of LMX quality over the diary days. Daily LMX quality predicted daily follower well-being (while controlling for morning well-being). Further, for those that interacted with their manager, social LMX exchanges but not economic exchange predicted daily well-being. Interaction characteristics (frequency, time, content) had a relatively small impact on daily well-being. As predicted, work engagement mediated the relation between daily LMX quality and social LMX exchanges and well-being but not daily economic LMX exchanges. The results show how LMX quality affects followers’ well-being that varies daily, that is affected by leaders’ behaviors
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
Forgiveness in leader-member exchange (LMX) relationships: A multi-study examination of mediating and moderating mechanisms
Get PDFDrawing upon theories from both the leadership and forgiveness domains, the overarching aim of this thesis was to answer a fundamental question. Namely, how and when does forgiveness unfold in Leader-Member Exchange (LMX) relationships and what are its outcomes? Even though it has been suggested that generic relationship knowledge from close relationship science can inform the understanding of LMX relationship maintenance, surprisingly little theoretical or empirical studies have addressed this area. By integrating both a framework of relationship maintenance mechanisms and a model of forgiveness in close relationships with LMX theory, study one developed and tested a model of forgiveness in LMX relationships. In a cross-sectional study involving 254 employees from eight organisations it was found that high LMX quality lead to higher job satisfaction and subjective well-being via greater follower’s forgiveness and subsequent follower’s relational efforts. Furthermore, it was found that higher levels of follower’s relationship self-efficacy and Leader-Member Exchange Social Comparison (LMXSC) enhanced follower’s forgiveness. The results of study one demonstrated that forgiveness of interpersonal transgressions in LMX relationships can lead to positive outcomes, and thus has important implications for LMX relationship maintenance and repair. Building on study one, study two adopted an experimental scenario design in order to examine the causal associations between LMX and forgiveness. Additionally, the study investigated the moderating role of forgiveness climate and the type of offence on follower’s forgiveness. The causal links between LMX and forgiveness were found for a competence-based offence but not for an integrity-based offence. Furthermore, it was found that forgiveness climate enhanced follower’s forgiveness in low quality (but not high quality) LMX relationships. This impact of forgiveness climate was found only following a low severity competence-based offence, and not following a high severity of competence-based or integrity-based offence. Overall, the findings of the thesis demonstrate that LMX relationships are vulnerable to interpersonal offences and that forgiveness could be used as a relationship maintenance strategy that yields positive outcomes
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
Ethics-related mentoring and protégé ethical behaviour:exploring the moderating role of mentor prototypicality and the mediating role of protégé moral motivation
Get PDFAlthough practitioners have strong incentives to select for and develop ethical managers, andscholars are increasingly interested in the study of ethical leadership in a post-Enron world,most of the research has dealt with the consequences of ethical leadership, but hasneglected to examine the antecedents to ethical leadership. This doctorate study addressesthis gap by investigating the conditions under which, and the mechanisms through which,mentoring at work can influence protégés’ ethical leadership behaviour and other ethicsrelatedoutcomes. To start research in this area, the prerequisite was to develop and test anew instrument to measure ethics-related mentoring – an additional dimension of mentoringthat is separate and distinct from the well-established mentoring functions in the literature(i.e., career-related mentoring, psychosocial mentoring, and role modelling). FollowingHinkin’s (1998) guidelines for scale development and validation, the first study included aseries of semi-structured interviews with key informants with the purpose of identifying anddefining the attitudes and behaviours associated with ethics-related mentoring. Thegenerated pool of items underwent a test of content (face) validity with subject-matter expertratings. A scale development study was then conducted to develop and validate the ethicsrelatedmentoring scale. This scale was then put to use in a time-lagged field study. Drawingon Bandura’s (1977, 1986, 1991) social cognitive theory, it was suggested that protégéperceptions of ethics-related mentoring influences protégé’s moral motivation which, in turn,impact his/her development of ethical behaviour. The moderating effect of mentorprototypicality on the relationship between ethics-related mentoring and moral motivationwas further examined. Analyses revealed that the proposed mediated moderationrelationships were not significant. However, strong interaction effects of both mentoringsubscales with mentor prototypicality on protégé moral motivation and directly on all outcomevariables (i.e., ethical leadership, OCB altruism, and turnover intentions) were seen
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
