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
Career Competencies and Career Success: On the Roles of Employability Activities and Academic Satisfaction During the School-to-Work Transition
No full textBuilding on the integrative career competencies framework, we examined the indirect association between career competencies, assessed at graduation, and subjective career success (SCS) via employability activities, both assessed six months after graduation, among a sample of 613 Italian graduates. We also examined the moderating role of three facets of academic satisfaction (i.e., vocational choice, educational goals, and occupational prospects). Our findings showed an indirect relation between career competencies and SCS through employability activities. Furthermore, academic satisfaction acted as a moderator. The results of this time-lagged study, that tapped into the actual transition into work process, have implications for (1) school-to-work transitions, providing insights into graduates’ transition into the labor market, (2) employability, focusing on employability activities and providing additional knowledge on their antecedents and outcomes,and (3) career competencies,providing further empirical evidence that career competencies are an important resource that graduates can mobilize to during and after their school-to-work transition
FE Analyses of a CFRP–Aluminum Single-Lap Hybrid Bonded/Bolted Joint at Different Tensile Loads
No full textJoints are often unavoidable and can be critical points in a complex structure made up of different sub-elements and materials, e.g., a lightweight aircraft structure. Joining can be performed with different techniques as mechanical fasteners, bonding, or hybrid bonded/bolted (HBB) solutions. HBB solutions are effectively used to join different materials, as metals and composites, leading to composite–metal HBB joint. In this paper, the structural behavior of a carbon fiber reinforced polymer (CFRP)–aluminum single-lap HBB joint is numerically investigated. Specifically, a detailed finite element model (FEM) is developed to study the joint subjected to an external tensile load. Analyses are conducted by considering two different bolt preloads and three external tensile loads (six tests in total). Results are compared with the aim to highlight the behavior of the joint, and in particular the stress–strain state in each component as a consequence of the applied load pair
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
