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
Role of Mediterranean Diet in bone health
No full textMediterranean Diet (MeDi) is a nutritional life style which has been developed in Mediterranean Countries. It is well known to be a balanced diet playing a key role in maintaining the good health of the individual, preventing chronic metabolic diseases, and optimizing genetic inheritance. It involves the presence of all macro- and micronutrients distributed in a balanced manner during the daily meals, with a prevalence of food of vegetal origin, such as cereals, legumes and olive oil, used as main dressing. Numerous recent studies have demonstrated the protective role of the MeDi on the skeleton, confirming that a definite and correct dietary approach such as MeDi can play an important key environmental factor for the maintenance on bone health and the prevention of osteoporosis
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
A School-Based Intervention Program to Reduce Weight Stigma in Adolescents
Full text linkBackground/Objectives: Weight-based stigma represents a pervasive psychosocial challenge affecting youth worldwide, with significant implications for mental and physical health. Although school-based interventions have been suggested as effective strategies to reduce weight bias, evidence regarding their content and efficacy in real-world educational contexts remains limited. The present study aimed to evaluate the effectiveness of a school-based intervention designed to reduce internalized weight stigma among Italian adolescents. Methods: A total of 539 secondary school students (Mage = 15.91 years; SD = 1.38; 51.5% males) from 10 schools in Italy were randomly assigned to either an intervention group (61.2%, n = 330) receiving the program or a minimal intervention control group (38.8%, n = 209). The intervention integrated psychoeducational modules and activities based on cognitive dissonance theory to address maladaptive weight-related attitudes and associated psychopathological outcomes. Pre- and post-intervention assessments evaluated internalized weight bias and body dissatisfaction in both groups. Results: A significant reduction in internalized weight bias was observed among students perceiving themselves as overweight following the intervention. Additionally, a marginally significant decrease in body dissatisfaction was reported in the intervention group from pre- to post-intervention. No comparable changes were found in the control group. Conclusions: These findings suggest that incorporating cognitive dissonance-based psychoeducational content within school-based programs may be a promising approach for reducing internalized weight stigma in adolescents. Further research is warranted to refine intervention strategies, explore the mechanisms underlying the observed effects, and assess the scalability and long-term impact of such initiatives in school settings
Oro-dental manifestations of eating disorders: a systematic review
Full text linkBackground Eating disorders (EDs) pose a significant risk to health, especially when not diagnosed early. For several years EDs and oral health has been extensively studied, and now it is quite clear the existence of a correlation between specific oral manifestations and these disorders. While these oral signs could potentially aid early diagnosis of EDs, their identification and the eventual establishment of a correlation is currently heavily limited to the clinician's experience. The present systematic review critically examines existing literature, offering an updated overview of oro-dental manifestations associated with EDs.Method MEDLINE (via PubMed), Web of Science, Scopus, and grey literature were searched, and relevant epidemiological comparative studies were screened using the Rayyan software. No limitations have been imposed on the research regarding oro-dental outcomes, encompassing all medically diagnosed EDs. The quality of the studies was valuated using AXIS appraisal tool for cross-sectional studies.Result Out of 3990 studies, 32 fulfilled the eligibility criteria and were included in the synthesis. The identified eating disorders include Anorexia Nervosa, Bulimia Nervosa and/or Eating Disorders Not Otherwise Specified, predominantly among female subjects, primarily originating from Europe. The evaluated oro-dental outcomes include dental erosion, caries, saliva assessment, hygiene-periodontal parameters, and mucosal tissue appearance. The association with erosion is confirmed while gingival recession, dentinal hypersensitivity, salivary flow thresholds and aspects relating to oral pathology are receiving increasing support from emerging evidence.Discussion This trend emphasizes the critical role of the complete intraoral examination to detect significant oro-dental signs that may indicate the onset of an ED.The article is a review of existing studies that explores the link between eating disorders and oral health issues. It found that people with eating disorders, including anorexia nervosa and bulimia nervosa, may experience dental problems such as tooth erosion, cavities, and altered saliva production. The review findings emphasize the importance of dental care providers recognizing these signs early and suggests better training for dental professionals. By doing so, they can help diagnose eating disorders sooner and recommend appropriate treatment. This approach aims to improve patients' overall wellbeing by addressing both the oral health issues and the underlying eating disorders, making it essential for patients and medical teams to be aware of the interconnectedness between oral health and eating disorders
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
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
