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
Heterogeneity of Members’ Characteristics and Cooperation within Producer Groups Regulating Geographical Indications: the Case of the “Prosciutto di Parma” Consortium
No full textConsumer willingness to pay for food quality labels: evaluating the prosciutto di parma PDO quality differentiation strategy
No full textThis poster paper aims to investigate the consumers’ preferences and willingness to pay for different quality strategies associated with the designations Prosciutto di Parma PDO. After a qualitative analysis, an on-line choice experiment was conducted on a sample of 250 Italian consumers. A multinomial logit model was tested to assess the relative importance of quality attributes. The results show that price, a “high quality” PDO label and the ageing period are the most important attributes for consumers. These findings provide Consortium members with an important food for thought for the development of future strategies for the Designation of Origin
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
E-learning courses at italian national institute of health: characteristics of dropout participants
Full text linkBackground. Over the last decades, the number of health professionals who participate in Continuing Medical Education (CME) through e-learning, has rapidly grown, due to its flexibility. In Italy, healthcare professionals in active clinical practice are required to keep their knowledge up to date, through this scheme.One of the most relevant challenges is represented by dropouts. Recent CME studies emphasize the dropout rates between 30% and 60 %. Since 2004, the Training Office of the Italian National Institute of Health (ISS) provides CME e-learning courses in public health, using Active and Problem Based Learning (PBL) methodology. The aim of this study was to identify characteristic of dropout participants in e-learning courses delivered during the 2017-2019 CME triennium. To understand factors that underline the dropout rate and consequently, hypothesize actions to improve retention and completion rates.
Methods. First we analyzed 21 courses (n= 44.630 participants) within the triennium 2017/19. Henceforth, we chose a single course for retrospective analysis. We ran a linear probability model through Stata 14.2, on age, gender, region, type of profession and occupation. Finally, we developed a matrix, based on the 7 steps of PBL, to identify the critical points of participants withdrawal.
Results. On the triennium 2017/19, we found the mean dropout rate of 34% and completion rate of 66%, with a great variability according to the level of interaction, enrolment modality, and accreditation. Based on five points LIKERT scale questionnaire on participants satisfaction into contents of the course, teaching methodology and platform function, out of 44.630, around 26635 (61.6%) who filled in the questionnaire, expressed their satisfaction (4.57 points out of 5). In the retrospective analysis, out of 11.198 participants, the retention rate was 6356 (56,8%) and dropout rate of 43,2% (n=4842). According to linear probability model, significance is noted on gender and age. Occupation type seems not to have significant differences in terms of retention between freelancers and unemployed compared to employed. Between regions and professions, there is also a variation in retention.
Conclusions. The results shade a light on key variables may be contributing to retention and dropouts, including critical points at the courses offered by ISS. Levels of interaction, gender and age seems to play a key role on participants to
withdraw either remain in the course
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
The resilient character of PDO/PGI products in dynamic food markets: the Italian case
Full text linkThe European and Italian food system is experiencing a change in the relationship with the consumer and with the distribution. In fact, customers are increasingly demanding, and are attracted, by products that have high quality content and a strong link with the territory.
The brands with the price are the two factors affecting the strategic policies of the food producer firms. At the same time, the retail system has proven to be very sensitive to consumer demands by providing quality products at competitive prices and using their brand as an element of loyalty.
In the European context, the Italian agri-food system has the higher number of products with the Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) recognition. However, 90% of PDO products are represented by only 15 Designations. This figure shows how different types of products find a much diversified business position in relation to the firm‟s characteristics, to the markets characteristics, to the reputation of the Designation and to the consortium strategies in relation to their commercialization.
The objective of this research, based on observed data collected through the survey of QUALIVITA Association, is to provide an exhaustive picture of the economic characteristics of the Italian PDO, PGI Designations and define a typology of such Designation according different set of variables as production system, reputation level, role of the territory and distribution channel.
The ultimate goal is to determine the strategic levers taken at the marketing stage and to identify which factors clarify their potentiality on the market.
The methodology adopted for the quantitative analysis is based on non-hierarchical cluster analysis by the method of k-mean in order to identify clusters of similar designations which explain what variables act on the various strategies adopted and on the related development processes
