Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Countering the scrooge in each of us: On the marketing of cooperative behavior..
No full textDe Vrek in Elk van Ons te Lijf Gaan Over het Bevorderen van Coöperatief Gedrag Veel sociale marketers veronderstellen dat de coöperatieve consument ged reven wordt door rationele beslissingen en dat zijn kennis, voorkeuren, en overtuigingen kunnen beïnvloed worden door informatieve campagnes en rationele argumenten met het oog op coöperatief gedrag. In dit doctoraat , staan we eerder stil bij de sociale consument als iemand die zich laat leiden door vuistregels; iemand die als het ware snel en vaak automatis ch beslissingen neemt. Daarbij onderzoeken we in drie verschillende manu scripten of subtiele signalen in de omgeving aangewend kunnen worden om de kans op een coöperatieve keuze te vergroten. Het eerste manuscript onderzoekt waarom NGOs en hulporganisaties mensen op straat gemakkelijk om een donatie vragen via de verkoop van een prod uct (vb. een sleutelhanger). De resultaten suggereren dat donateurs eige nlijk al iets immaterieels kopen wanneer ze doneren (vb. een goed gevoel ) en dat ze daarom niet op zoek zijn naar de aankoop van extra donatie product. In plaats daarvan is het beter om donateurs een indicatie te ge ven van een sociaal acceptabel donatiebedrag. We moeten als het ware de transactie zo gemakkelijk mogelijk laten verlopen door er een prijs op t e plakken. In het tweede manuscript, bestuderen we hoe ons verlangen naa r voedsel ons verlangen naar geld doet toenemen en omgekeerd. We probere n een evolutionaire verklaring te bieden voor het (sterke) menselijk ver langen naar geld in onze moderne maatschappij. Ons verlangen naar geld z ou dan een moderne aanpassing zijn van ons eeuwenoud verlangen naar voed sel. Het laatste artikel test een instrument dat door non-profit organis aties en commerciële marketers kan gebruikt worden om coöperatief gedrag te bevorderen. Vier studies tonen aan dat mensen een interviewer gemakk elijker zullen helpen als ze voordien veel akkoord zijn gegaan met de in terviewers stellingen. We tonen aan (1) dat dit proces gedreven wordt do or een verhoogde perceptie van gelijkheid met de interviewer en (2) dat het proces voor een groot deel automatisch verloopt.
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

The development of children’s beliefs about the trade-off between health and taste in food and the long-term consequences for body weight and related health problems
No full textThe escalating global obesity epidemic presents severe health, economic, and social challenges. Over the past four decades, obesity rates have nearly tripled; in 2016, over 650 million adults were considered obese, comprising about 13% of the global population, and this prevalence rose to 19% among women and 13% among men by 2022. Childhood obesity is particularly alarming, affecting over 340 million children and adolescents worldwide. Not only does it diminish children's quality of life and increase their risk of diseases, but it also raises the likelihood of bullying and tracks into adulthood, heightening the risk of chronic conditions like diabetes and heart disease. The dramatic rise in global obesity rates is driven by shifts toward high-calorie, nutrient-poor diets, and more sedentary lifestyles, exacerbated by urbanization and economic development. Moreover, socio- economic disparities contribute, as lower-income families may lack access to healthy foods and safe physical activity spaces.
Lay beliefs about health and food significantly impact eating behaviors and are shaped by cultural norms and personal experiences. For instance, beliefs about the relationship between taste and health—such as the "Unhealthy = Tasty Intuition" (UTI)— can drive people towards unhealthier dietary patterns, influencing long-term eating habits and contributing to obesity. This dissertation explores how the UTI develops. In Chapter 2 and 3, new measurement methods of the UTI are proposed. One is a simple measure tailored to children, the other is an implicit measure based on mouse tracking techniques. Chapter 4 examines whether parents socialize this belief to their children. Chapter 5 extends this idea and examines whether food choice independence triggers the development of the UTI. Finally, Chapter 6 examines whether the other culturally evoked beliefs such as the belief in a just world are reflected in the UTI.
This dissertation underscores the need for early intervention and targeted research to understand and mitigate factors influencing unhealthy dietary behaviors. It also highlights the importance of culturally tailored interventions that consider the unique dietary beliefs and behaviors within different populations to effectively combat the global obesity crisis
