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
An Experimental Field Study on the Effects of Coaching: The Mediating Role of Psychological Capital
No full textCoaching is a developmental intervention implemented in organisations to improve individual attitudes and behaviours. Few studies, however, have tested these assumptions and explained the mechanisms involved. We propose psychological capital (PsyCap), a set of positive individual resources, as a possible mediator. We investigated whether coaching framed in goal setting and conservation of resources theories is effective in improving PsyCap and, through this, individual attitudes and performance, and whether its effects maintain over time. We conducted an experiment with 56 employees in a marketing company, who were either randomly assigned to a coaching intervention or a wait-list control group. Measures of interest were collected before the programme started (T1), and after the programme, which lasted 4 months (T2). A follow-up measure for the experimental group was collected after a further 4 months (T3). ANOVAs showed coaching was associated with increases in PsyCap, job attitudes, and one dimension of job performance. The mediating role of PsyCap was supported for job attitudes. The effects on PsyCap and job attitudes lasted over time, as revealed by within-subjects repeated measures analyses. This study fills a gap in our knowledge of the explanatory processes of coaching effectiveness by building on solid research design features
Quo Vadis? A study of the state and development of coaching in Portugal
No full textAlthough coaching programs are becoming increasingly widespread across the world, in some countries this practice has only been introduced in recent years. To better understand the coaching context in one such country, Portugal, and to identify future trends and directions, a survey was carried out among 255 coaches via social media, using the snowball approach. We aimed to uncover the predominant background of coaches and whether this is associated with features of their practice, most notably their theoretical positions and the use of any tools or instruments. We also explored aspects related to the coachees’ most recurrent needs for coaching, and the positive and negative effects that coaches observe more frequently. The results of this descriptive study reveal, among other things, that there is room for more theory-driven methodologies that can be replicated and standardized and, therefore, ultimately contribute to coaching professionalization
What changes with coaching? Investigating within-person changes in reflection, the predicting role of implicit person theory and the effects on perceived utility of coaching
No full textCoaching literature assumes that people undergo personal change through coaching. We contend that different types of change may occur with coaching and investigate whether this is the case in reflection (a key competence in coaching). Results from our sample of 61 coachees indicate that three types of change (alpha, beta, gamma) are observed across participants. Alpha change refers to a substantive change in reflection (i.e. an increase or decrease), beta to a recalibration of one's assessment of reflection and gamma to a re-conceptualization of reflection. We further examine implicit person theory (IPT) as a predictor and perceived coaching utility as a correlate of the three types of change. We observe a higher probability that incremental IPT will associate with alpha change versus other types of change, and that beta and gamma changes correlate positively and negatively, respectively, with perceived utility for work. No significant correlations are observed between types of change and perceived utility for personal development. Our study represents an exploratory contribution to a better understanding of the within-person changes in reflection following coaching intervention, and has implications for both theory and practice, which we discuss along with indications for future directions
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
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
