Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

*these members are joint last authors.
Objectives:
Identify top 10 Research Priorities for the management of Parkinson’s;
Align research priorities of healthcare professionals with People with Parkinson’s (PwP);
Compare differences in priorities across geographical location;
Identify unanswered priorities to guide future research;
Guidance on how we disseminate results to participants.
Background:
In 2014, Deane et al. identified the Top 10 research Priorities for Parkinson’s, asking people what they wanted to see addressed by clinical research. Participants at a research open-day, were shown the survey and rated their priorities differently. We want to update the priorities to align with our participants, collaborating with our colleagues in Germany and Luxembourg with similar Parkinson’s cohorts.
Methods
Participants will include PwP, friends/family, healthcare professionals, researchers/students and members of email lists associated with the three cohorts. All will be invited to complete the same survey.
A modified Delphi process will be used whereby in the first round of survey, participants may add a question they feel is not represented by the list of 27 questions (taken from 2014 survey). Participants will be asked to rate each question on how important it is to them on a scale of 1-9.
Free text responses will be organised in to themes and the most popular 10 will be added to the list for the Delphi panel (50 randomly selected Oxford participants) to rate again.
Some demographics will be collected to allow for sensitivity analyses on whether confounders change the priorities.
Results
The median and interquartile ranges for each question will be calculated then ordered in ranking of priority.
Conclusion
Guidance for future research and results dissemination will be made. A systematic search of current research published, registered or ongoing will be conducted and compared to the most important priorities
Variations on the Author
Get PDF“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
Get PDFWe 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
A mixed-methods investigation of the trajectories of patient-reported functional mobility in people with Parkinson's disease
Get PDFFunctional mobility in PD worsens as the disease progresses, leading to increased care needs and costs. This dissertation aimed to understand determinants of functional mobility, unexpectedly stable trajectories, and the experiences of men and women with Parkinson’s disease. The research employed a mixed-methods approach, combining quantitative analyses of longitudinal data with qualitative interviews. Key findings and methodological aspects include: - Validation of the Functional Mobility Composite Score (FMCS) for assessing patient-reported functional mobility. - Identification of environmental factors as important determinants of functional mobility.- Observation of slower symptoms progression in women compared to men. - Investigation of genetic variants and their association with functional mobility. - Exploration of factors associated with unexpectedly stable trajectories of functional mobility. The findings contribute to a better understanding of functional mobility in PD and may inform strategies to delay institutionalization and improve patients' quality of life. Thus, this work is relevant for healthcare professionals, researchers, and policymakers involved in PD management, as it provides insights into factors associated with functional mobility and potential interventions to maintain the independence and well-being in men and women with Parkinson’s disease
A MIXED-METHODS INVESTIGATION OF TRAJECTORIES OF PATIENT-REPORTED FUNCTIONAL MOBILITY IN PEOPLE WITH PARKINSON’S DISEASE
Get PDFFunctional mobility is one of the disease-related features most relevant to people with PD (Bowring et al., 2022). It worsens as the disease progresses (Lindh-Rengifo et al., 2021, Mirelman et al., 2019) resulting in increasing professional care and nursing home costs (Chaudhuri et al., 2024). A promotion of mobility and functionality could help to delay institutionalisation and respect the desire of people with PD to remain in their homes (Habermann and Shin, 2017). This dissertation aimed to understand determinants of functional mobility, the phenomenon of unexpectedly stable trajectories for functional mobility and their experience in people with PD. CHAPTER ONE introduces the impaired functional mobility in Parkinson’s disease, life with a chronic disease, longitudinal data analysis of the Luxembourg Parkinson’s Study, the mixed-methods design and the involvement of individuals with PD in the dissertation. Using data from the Luxembourg Parkinson’s study, a nationwide, observational, longitudinal-prospective and dynamic cohort, CHAPTER TWO reports the assessment of convergent and discriminative validity of the Functional Mobility Composite Score (FMCS). The FMCS is an algorithm based on the Parkinson’s Disease Questionnaire-39 (PDQ-39) to assess patient-reported functional mobility in a multilingual context of Luxembourg. To get an overview of the current state of research, CHAPTER THREE reports a systematic review concluding future research on patient-reported functional mobility should focus among other on environmental factors as determinants. In preparation of the longitudinal analyses, CHAPTER FOUR demonstrates in a comparative analysis, how the choice of statistical method may influence research outcomes. Using the previously established and validated methodology, CHAPTER FIVE applies linear mixed-effects models to deal with the differential trajectories of patient-reported functional mobility and the motor- and nonmotor symptoms in men and women with PD. An overall slower disease progression was observed in women compared to men. As the development of Parkinson’s disease (PD) is influenced by genetic and environmental factors and the role of PD-risk GBA1 variants is not yet well understood, CHAPTER SIX compares the progression of patient-reported functional mobility and other symptoms in individuals with different genetic GBA1 variants (Gaucher-related or PD-risk GBA1 variants) and the non-carriers. The GBA1-variants were not associated with a slower decline of patient-reported functional mobility. Nevertheless, a reevaluation of their pathologic relevance would be warranted if these findings are confirmed in an independent cohort due to the described effect modification of the nonmotor symptoms. To better understand the phenomenon of unexpectedly stable trajectories of functional mobility and the protective factors involved, CHAPTER SEVEN reports a sequential explanatory mixed-methods study. First mixed effects models investigated the effect modification of relational (partner, children), cognitive (educational attainment), and socioeconomic (place of residence) reserves on the trajectory of patient-reported functional mobility. Then qualitative semi-structured interviews with participants experiencing an unexpectedly stable trajectory of functional mobility explored their perceptions of barriers and facilitators related to those reserves. Characteristics of individuals with unexpectedly stable trajectories of patient-reported functional mobility that emerged from the inductive analysis were psychosocial factors similar to self-efficacy, chronic inflammatory diseases and self-care activities promoting a physically active lifestyle. Finally, CHAPTER EIGHT of this dissertation synthesises and discusses the results of all chapters, the methodological considerations and presents future directions and the overall conclusions of this dissertation
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
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
