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

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
Organizational and individual work-related factors on longitudinal nurse employee outcomes and productivity costs
No full textPresenteeism is the behaviour of employees being physically present at work but with reduced performance. It impairs employee health and affects team productivity resulting in high financial costs wthat potentially exceed those of absenteeism. Nurses are more prone than other occupations in exhibiting presenteeism and is associated with adverse patient outcomes.
Hong Kong public hospitals provide 90 percent of all inpatient services, public hospital nurses work in high-intensity inpatient settings. In addition, Hong Kong is situated in the subtropical climate region, bimodal influenza winter and summer flu surge outbreaks introduces additional stress to an already saturated system, which may bring undesirable impacts on nurse employee outcomes in hospitals. Other than external environmental influence, organizational and individual factors play a role in employee work behaviour. This thesis takes a multi-level approach to address the impact of external, organizational and individual factors on nurse presenteeism and productivity.
The objectives of this study were to 1) quantify Hong Kong public hospital nurse presenteeism prevalence, related productivity costs, and association with workload (as proxied by hospital occupancy rates); 2) quantify the impact of ward- level organizational culture and leadership style on presenteeism and productivity; 3) evaluate the impact of ward-level leadership, individual work factors, workload and personal health locus of control on employee outcomes and 4) identify multi-level mediation pathways between work and individual variables on presenteeism and productivity based on the Jobs Demands-Resources model.
All full-time nurses from three Hong Kong acute care public hospitals with distinctive historical, cultural and religious context (NH1= 2145, NH2=1367 and NH3=1145) were invited to participate in this 3-wave prospective study. The collection periods corresponds to the three service utilization patterns (seasonal winter flu surge (March 2017), summer flu surge (July 2017) and normal (October 2017)). Generalized estimating equation (GEE) and hierarchical linear modelling (HLM) were used to account for the clustering dependency and hierarchical nature of data.
Higher presenteeism patterns in the sample compared to prior studies in western contexts may be attributed to cultural variation. Productivity loss costs among nurses working healthy, working sick and took sick leave were not significantly different. Total costs of nurses who took sick leave (productivity loss and sick leave costs) were highest. The impact of ward-level organizational culture on nurse presenteeism and productivity may differ by distinct hospital founder societal culture and mission.
This study also provided a temporal and multi-level perspective on the impact of ward-level leadership style and individual factors on employee outcomes. During winter flu surge, presenteeism level and work engagement was highest and nurse productivity plateaued. Whereas higher burnout was observed during less heavy workload period. Laissez-Faire passive and Confucius transformational leadership style did not directly impact presenteeism and productivity. However, the two types of leadership impacted presenteeism and productivity through the mediation of individual work resources. Work resources and health locus of control have comparable effects on improving presenteeism and productivity, which could be maneuvered by hospital management. This study provides evidence to support the formulation of future human-resources strategic measures in the future.published_or_final_versionPublic HealthDoctoralDoctor of Philosoph
