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
The impact of digital corporate branding on consumer - company identification
No full textDeveloping a distinctive image in the marketplace is increasingly recognized as a key part of a company’s marketing strategy and a route for achieving competitive advantage. Strong corporate brands (CB) can lead to a wide customer base and a distinctive image. As product and service offers become similar, companies tend to emphasize the communication of CBs to stakeholders as a way to convey distinctiveness and uniqueness. Nonetheless, although CB focuses primarily in reaching all the company’s stakeholders, consumers are increasingly becoming a core target for corporate branding. Consumers are exposed to the image portrayed by a company online. The website, therefore, can be a reflection of the company’s CB’s characteristics and personality and a company’s online atmospherics and its online stores may have an impact on consumer behaviour. In the online context, the CB dimensions of visual appeal, the way the information is communicated, and social responsibility are crucial. A well-liked corporate website could lead to favourable behavioural outcomes, such as positive word of mouth, and repatronage intentions. Despite the obvious commercial benefits and the recent research attention on online corporate branding, the impact of online dimensions of CB in consumer perceptions is overlooked. Our study investigates the impact of three online CB dimensions (visual appeal, communications, CSR) on consumer-company identification (CCI), and the behavioural outcomes (word of mouth, repatronage intention) in retail sector. We employed a scenario-based quasi-experiment in two retail settings—grocery and clothing—using two fictitiously created brands and their websites. Three scenarios for each brand were created representing high, medium, and low levels of descriptions of dimensions of CB on the websites. A questionnaire was created and the scales operationalization relied on adaptations from previous research. Following a pilot, the data were collected via web-based survey software, using a convenience sample of cross-section demographics of UK consumers, resulting in 244 valid responses. We tested the hypothesized relationships using partial least squares-based structural equation modelling (PLS SEM). The results show that the way in which a company communicates its CB online, as well as its socially responsible activities, positively influences consumers’ identification with the company. Such identification also leads to the generation of positive word of mouth and repatronage intentions. The results also reveal that high degree of information placed on a website is not the most optimal tool for generating positive CCI. Further, stronger the firm’s portrayed engagement in corporate giving, the more a consumer identifies with the firm. Overall, the study makes novel contributions to the domain of CB and its impact on consumer perceptions, and leads to several managerial implications and avenues for further research.</p
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
World Health Organization (WHO) and the World Heart Federation (WHF) Pathobiological Determinants of Atherosclerosis in Youth (PBDAY) Study. Lipid and raised lesion distribution in the right coronary artery of young people
No full textBACKGROUND AND AIM: As part of the WHO-WHF PBDAY Study, we examined the proximal segment of the right coronary artery (RCA) (n = 469) of 5-34 yr-old otherwise healthy trauma victims from 15 countries to establish the topographical relation of atherosclerotic lesions to age, sex and geographical location.
METHODS AND RESULTS: Topography and extent of lesions were analyzed by image processing and probability-of-occurrence maps of lipid lesions (mostly fatty streaks) and raised lesions on the intimal surface of the RCA were produced. Extension of lesions varied considerably between the groups and between individuals in the same group. The prevalence of lipid lesions was 68% (319/469) compared with 100% in the aorta. The prevalence of raised lesions was 22% (102/469) compared with 7% and 26% in the thoracic and abdominal aorta. Females had more lipid lesions, whereas raised lesions prevailed in males. Lipid lesion extent increased with age in both sexes.
CONCLUSIONS: High probability-of-occurrence areas for lipid and raised lesions prevailed in the proximal 5 cm of the intimal surface of the RCA (myocardial side) and were greatly overlapping. Regression analysis between lipid and raised lesion extent in the thoracic or abdominal aorta and the RCA showed no correlations between the lipid lesion extent, whereas significant correlations were found between the raised lesion extent in the RCA and the thoracic aorta only, showing that the two types of lesion behave differently in different anatomical locations
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
Assessing the influence of electrostatic schemes on molecular dynamics simulations of secondary structure forming peptides
No full textElectrostatic interactions play a fundamental role in determining the
structure and dynamics of biomolecules in solution. However the accurate
representation of electrostatics in classical mechanics based simulation
approaches such as molecular dynamics (MD) is a challenging task. Given
the growing importance that MD simulation methods are taking on in the
study of protein folding, protein stability and dynamics, and in
structure prediction and design projects, it is important to evaluate
the influence that different electrostatic schemes have on the results
of MD simulations. In this paper we performed long timescale simulations
(500 ns) of two peptides, beta3 and RN24 forming different secondary
structures, using for each peptide four different electrostatic schemes
(namely PME, reaction field correction, and cut-off schemes with and
without neutralizing counterions) for a total of eight 500 ns long MD
runs. The structural and conformational features of each peptide under
the different conditions were evaluated in terms of the time dependence
of the flexibility, secondary structure evolution, hydrogen-bonding
patterns, and several other structural parameters. The degree of
sampling for each simulation as a function of the electrostatic scheme
was also critically evaluated. Our results suggest that, while in the
case of the short peptide RN24 the performances of the four methods are
comparable, PME and RF schemes perform better in maintaining the
structure close to the native one for the beta-sheet peptide beta3, in
which long range contacts are mostly responsible for the definition of
the native structure
