All for one, one for all: coopetition and virtual team performance
No full textThis study establishes a model based on coopetition theory to explain the formation of team performance in virtual teams. We tested the model in information technology (IT) organizations, and found applicability of coopetition in influencing team performance and knowledge sharing. Knowledge sharing is indirectly influenced by team politics and social capital (i.e., trust, social interaction and shared vision) via the mediation of cooperation and competition, while team performance is indirectly affected by team politics and social capital via the mediation of cooperation, team emotional intelligence and team competence
Modeling team knowledge sharing and team flexibility : the role of within-team competition
Full text linkThis study examines the role of within-team competition (i.e. team hypercompetition and team development competition) in a team process. We developed and tested a model that associates team collectivism as the antecedent of within-team competition, and knowledge sharing and team flexibility as the outcomes. The model was empirically tested with data from 141 knowledge-intensive teams. The empirical findings showed that team collectivism had a positive relationship with team development competition and a negative relationship with team hypercompetition. Regarding the outcomes, team development competition and team hypercompetition had an indirect relationship with knowledge sharing and team flexibility through team empowerment. We offer a number of original contributions to the team effectiveness literature, especially by showing that team hypercompetition and team development competition have different impacts on team knowledge sharing and team flexibility

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
Customer-supplier Relationship and Cost Stickiness
No full text傳統的成本模型指出變動成本應與銷貨收入成等比例的變動。然而Anderson et al.(2003)的研究指出許多成本具有僵固性- 成本在銷貨收入上升時的調整幅度大於當銷貨收入下滑時調整之幅度。本研究調查顧客與供應商關係對於公司成本結構的影響。實證結果指出，當供應商的顧客集中度越高時，該供應商的成本結構較不僵固。傳統的顧客與供應商關係理論指出主要顧客較強的議價能力能迫使供應商保留產能，導致成本僵固。然而我們的實證結果指出，供應商與顧客關係將使雙方有更密切的資訊交流，供應商與顧客的資訊交流溝通使得供應商能及時調整產能，因此成本較不僵固。本研究指出供應商與顧客關係應為研究公司成本結構時應考量之因素。Traditional model of cost behavior assumes that cost changes proportionally with sales. However, Anderson et al. (2003) show that costs may behave sticky in the sense that costs increase in response to the increase in sales, but do not decrease proportionately when sales decrease by the equivalent amount. This study investigates whether and how relationship with major customers can affect its cost stickiness. The evidence shows that costs are less sticky for firms which have higher concentrated customer bases. Different from the conventional view, which suggests that major customers may pressure suppliers to retain resources when sales decrease and thus, increase the stickiness of cost, the study finds that suppliers have more information from their customer-supplier relationship through better information transfers along the supply chain. Suppliers are more certain about future demand, thus adjusting their costs accordingly in time. Overall, my study shows the importance of customer-supplier relationship when analyzing a firm’s cost behavior
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
