Psychophysiological correlates of glucose monitoring frequency in diabetes mellitus
No full textAims: Diabetes mellitus (DM) is a chronic metabolic disorder characterized by heightened blood glucose levels.
Prevention of DM complications relies heavily on self-management, including frequent monitoring of blood glucose
levels. The goal of this study was to investigate psychological and physiological correlates of blood glucose monitoring
frequency (BGM frequency) in DM patients using a continuous blood glucose monitoring sensor connected to a
electronic reading system.
Methods: Fifty-nine DM patients (26 women; 49 DM type 1) wearing a continuous blood glucose monitoring sensor
filled out the Hospital Anxiety and Depression Scale, the Need for Controllability and Predictability Questionnaire, and
the Action and Acceptance in Diabetes Questionnaire. The number of glucose sensor readings was recorded daily from
the monitoring system for three months.
Results: Sixty-three percent of patients had an HbA1c value over 7. Anxiety, depression, and traumatic experiences
levels were overall low in our sample (10% had a HADS depression score > 12, and 12% had a HADS anxiety score > 12).
On average, patients read out their blood glucose levels 7.83 times per day (SD = 3.60). BGM frequency was negatively
correlated with HbA1c levels (r = -0.355, p = 0.018). No associations between (BGM frequency) on the one hand and
depression, anxiety, need for control, or experiential avoidance on the other hand, were found.
Conclusion: Patients who measured their glucose levels more frequently had lower HbA1c values, and thus better long-
term glucose control. Frequency of blood glucose measuring was unrelated to the psychological variables included in
this study

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
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
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
Statistical estimation of physical properties of cell monolayers
No full textLes cellules épithéliales forment des tissus cohésifs, sous forme de monocouches que l'on retrouve dans les poumons, les reins ou la peau. Travaillant à partir d'expériences in vitro, nous avons caractérisé le comportement mécanique de monocouches cellulaires. Nous avons étudié la fermeture de blessures circulaires sur un substrat non adhésif. En comparant différents modèles, nous avons montré comment la fermeture est possible grâce à un cable contractile d'acto-myosine et aux fluctuations de la tension du tissu. La Microscopie des Forces de Traction (TFM) permet de mesurer les forces que les cellules exercent sur leur substrat. A partir de cette mesure et en utilisant l'équilibre des forces, nous avons développé une méthode qui résout ce problème sous-déterminé par inversion bayésienne et permet d'obtenir le champ des contraintes internes au tissu. En appliquant cette méthode sur des images (BISM: Microscopie des contraintes par inversion bayésienne) et en l'adaptant à l'aide d'un filtre de Kalman sur des films (KISM: Microscopie des contraintes par inversion de Kalman), nous avons inféré le tenseur des contraintes de monocouches cellulaires sans faire aucune hypothèse sur la rhéologie du tissu. Enfin, nous avons estimé les contraintes directement depuis les déplacements du substrat, sans passer par les forces de tractions et donc en réduisant le nombre d'inversions de matrice (BISMu: Microscopie des contraintes par inversion bayésienne à partir des déplacements du substrat).Epithelial cells are known to form cohesive monolayers, a form of tissue organization encountered in the lung, the kidney or the skin. From in vitro experiments, we have characterized the mechanical properties of cell monolayers. We have studied the closure of circular wounds over a nonadhesive substrate. Comparing different models, we have shown how closure is possible thanks to a contractile acto-myosin cable and to fluctuations of the tissue tension. Traction Force Microscopy (TFM) allows to measure the forces that cells exert on their substrate. Starting from this measurement and using the force balance equations, we have solved this underdetermined problem by Bayesian inversion and obtained the internal stress field of the tissue. Applying this method on single images (BISM: Bayesian Inversion Stress Microscopy), and adapting it with a Kalman filter for movies (KISM: Kalman Inversion Stress Microscopy) we have inferred the stress tensor of cell monolayers, without making any hypothesis on the tissue rheology. Finally, we have estimated the stresses directly from the substrate displacements, without computing the traction forces and thus reducing the number of matrix inversions (BISMu: Bayesian Inversion Stress Microscopy from substrate displacements)
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
