Strength in Numbers? Understanding the Effect of Team-Level PSM on Team Effectiveness
Get PDFTo date, public service motivation (PSM) has been investigated only as an individual-level phenomenon. We argue that, in order better to understand team effectiveness in public organizations, it is essential that team characteristics are also taken into consideration. This study provides a key contribution to public management research by exploring the relationship between PSM and team effectiveness at the group level. Specifically, we introduce the concepts of team-level PSM, which describes the average level of PSM within a team, and PSM differentiation, which refers to the variance in PSM that exists across different members of a team. The data used for this study are based on a two-wave survey of 122 teams of public sector employees in Switzerland. Findings show that team-level PSM is indirectly related to team effectiveness through the process of team identification and that this relationship is strengthened when there is less variability in PSM within the team. The implications of our findings for theory and practice are discussed
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
Oil Wealth and Policical (In)stability: Is it really the rents?
No full textResearchers at the Political Instability Task Force (PITF) recently published an article identifying regime type, infant mortality rates, level of state led discrimination and the stability of bordering states as best measures for predicting the onset of political instability. None of the additional variables tested were significant and improved the model‟s forecasting ability. Additional variables included natural resource dependence of a state. This measure was constructed using ratios of export revenues based on crude oil, petroleum, ores and metals. The purpose of this research paper is to test an alternative means of measuring resource dependency by focusing directly on the relationship between oil rents and political instability. As such, an „oil rent per capita‟ variable was created and tested alongside the PITF‟s variables. A conditional-regression analysis revealed a significant negative relationship between oil rents and political stability. However, the new measure did not improve the overall forecasting ability of the model. Notable findings also include an increase in odds of conflict in partially democratic states that exhibit factionalism. Several theoretical and methodological reasons for these findings are presented
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
