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
Η εν γένει οργανωσιακή κουλτούρα που επικρατεί στα κέντρα υγείας. Η περίπτωση των κέντρων υγείας Ηγουμενίτσας, Μαργαριτίου και Παραμύθας
No full textΠεριέχει βιβλιογραφικές παραπομπές.Εισαγωγή: Ως οργανωσιακή κουλτούρα θεωρείται η συλλογική συμπεριφορά των ανθρώπων που αποτελούν μέρος μιας οργάνωσης, και αποτελείται από τις αξίες της οργάνωσης, τα οράματα, τους κανόνες, τη γλώσσα εργασίας, τα συστήματα, και τα σύμβολα αυτής, ενώ περιλαμβάνει και τις ευρύτερες πεποιθήσεις και συνήθειες. Η οργανωσιακή κουλτούρα επηρεάζει τον τρόπο που οι άνθρωποι και οι ομάδες αλληλεπιδρούν μεταξύ τους, με τους πελάτες, και με τα ενδιαφερόμενα μέρη. Η οργανωσιακή κουλτούρα επηρεάζει την απόδοση και ορθή λειτουργία του κάθε οργανισμού, ενώ όσοι λειτουργούν σε αυτόν μπορεί να αντιμετωπίσουν εσωτερικές συγκρούσεις, που θα καλείται η οργανωσιακή κουλτούρα να επιλύσει
Σκοπός: Σκοπός ης εργασίας αυτής είναι να μελετηθεί η οργανωσιακή κουλτούρα στα τρία κέντρα υγείας, Ηγουμενίτσας, Μαργαριτίου και Παραμυθιάς.
Μεθοδολογία: Για τη διπλωματική αυτή μοιράστηκαν και συμπληρώθηκαν 49 ερωτηματολόγια με 43 ερωτήσεις κλειστού τύπου στα τρία κέντρα υγείας. Οι 26 από αυτούς ήταν νοσηλευτές, οι 22 ιατροί, ενώ 1 δεν δήλωσε την ιδιότητά του. Για την ανάλυση του ερωτηματολογίου, οι ερωτήσεις κατηγοριοποιήθηκαν, ώστε να εξεταστούν οι παράγοντες «υποστηρικτικότητα», «καινοτομία», «ανταγωνιστικότητα», «προσανατολισμός στην απόδοση», «σταθερότητα», «έμφαση στην ανταμοιβή» και «κοινωνική ευθύνη». Για την εξέταση αυτών των παραγόντων χρησιμοποιήθηκε ο συντελεστής εσωτερικής συνέπειας alpha του Cronbach και η τιμή αξιοπιστίας αξιολογήθηκε με τα κριτήρια των George and Mallery (2003).
Αποτελέσματα: Όπως προέκυψε από την ανάλυση των αποτελεσμάτων ο παράγοντας της υποστηρικτικότητας, ήταν ο παράγοντας ο οποίος παίζει πολύ σημαντικό ρόλο για τους εργαζομένους και παράλληλα αυτός που δεν ικανοποιείται σε σημαντικό ποσοστό στο εργασιακό περιβάλλον. Σημαντικό αποτέλεσμα ήταν επίσης η εξέταση του παράγοντα της καινοτομίας έφερε αμφισβητήσιμα αποτελέσματα σχετικά με τη σημαντικότητα και την ικανοποίησή του.
Συμπεράσματα: Για να βελτιωθεί η κατάσταση στα τρία Κέντρα Υγείας καλό θα ήταν να αναθεωρήσουν τις αμοιβές τις οποίες δίνουν στους εργαζόμενους, τόσο τις σταθερές οικονομικές αμοιβές τους, δηλαδή το μισθό τους, όσο και τις μεταβλητές αμοιβές ή και τα γενικότερα κίνητρα τα οποία μπορούν να βοηθήσουν στην αύξηση της απόδοσης των

υπαλλήλων, όσο και άλλες αμοιβές μη οικονομικές, οι οποίες σχετίζονται με το περιεχόμενο και το περιβάλλον εργασίας, όπως η αναγνώριση, η επιβράβευση, η ανάπτυξη, η εκπαίδευση, οι προοπτικές καριέρας και η βελτίωση των συνθηκών εργασίας.Introduction: Organizational culture is the collective behavior of people within an organization and consists of the organization's values, visions, rules, language, systems and symbols, and includes its broader beliefs and habits. Organizational culture affects how people and groups interact with each other, with customers, and stakeholders. It also affects the performance and effectiveness of any organization, and those who work in it may face internal conflicts, which organizational culture is called to solve.
Purpose: This essay studies organizational culture in three health centers, Igoumenitsa, Margaritiou and Paramithias and furthermore examines the role conflict and ambiguity of roles within them.
Methodology: For the thesis 49 questionnaires were returned completed with 43 closed type questions in the three health centers. The 26 participants who answered were nurses, 22 doctors, and 1 did not report a job status. For the analysis of the questionnaire, questions were categorized in order to examine the factors of "support", "innovation", "competitiveness", "performance orientation", "stability", "focus on the reward" and "social responsibility." To examine these factors the Cronbach’s alpha internal consistency coefficient was used wghile reliability was assessed by the criteria of George and Mallery (2003).
Results: The support factor was the one that played a very important role for employees while it was not satisfied to a great extent for a significant proportion of the working environment. Another significant result was also that the factor of innovation had questionable results on terms of its importance and its fulfillment.
Conclusions: To improve the situation in the three health centers a review of the employee rewards is needed both in terms of stable economic rewards, ie wages, and other variable fees, or general incentives that can help increase the efficiency of employees, as well as other non-economic factors, that relate to the content of the job and the working environment, such as recognizing, rewarding, development, education, career prospects and better working conditions
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
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
Dietary exposure to persistent organic pollutants during pregnancy and child health
Full text linkIntroduction
Diet is the main source of exposure to persistent organic pollutants (POPs), including dioxins and PCBs. During pregnancy the fetus is exposed to POPs which can lead to adverse health effects. The research hypothesis of this thesis is that maternal diet, as a source of prenatal exposure to POPs, may be linked to impaired fetal growth and endocrine disruptive effects.
Methods
This thesis included 604 mother-child pairs from the European NewGeneris project, 50,651 mother-child pairs from the Norwegian Mother and Child Cohort (MoBa) and 707 mother-child pairs from the Rhea and the Hmar studies. Dietary data were collected during pregnancy by food frequency questionnaires. Three approaches were used to derive dietary estimates of prenatal exposure, either related to levels of POPs in maternal and cord blood or in food. Birth outcome information was obtained by medical registries. Anogenital distance measurements were collected and used as a marker of endocrine disruptive effects. Main predictors of anogenital distance were assessed and a reliability study was conducted.
Results
In the NewGeneris project, a dioxin-diet characterized by high maternal intakes of meat and fish was positively related to dioxins and dioxin-like compounds in maternal blood. High adherence to the dioxin-diet was associated with a reduction of -115g in birth weight. In the MoBa study, an inverse dose-response association was found between dietary dioxins and PCBs intakes during pregnancy and birth size. The negative association remained even for intakes lower than the tolerable weekly intake. In the Rhea and Hmar studies, anogenital distances were related to growth, tracked through early life and were highly reliable anthropometric measurements. A high-fat diet score during pregnancy was positively related to POPs in maternal blood and was associated with 15% reduction in anogenital distance of newborn boys.
Conclusions
Diet during pregnancy can influence maternal and fetal body burden of POPs. Prenatal exposure to POPs, through maternal diet, may lead to impaired fetal growth and endocrine disruptive effects, even in populations with low background exposures to POPs.Introducció
La dieta és la principal font d'exposició als contaminants orgànics persistents (COP), com les dioxines i els PCBs. Durant l'embaràs el fetus està exposat als COPs, que poden donar lloc a efectes adversos per a la salut. La hipòtesi principal d'aquesta tesi és que la dieta materna, com una font d'exposició prenatal als COPs, podria estar relacionada amb alteracions en el creixement fetal i efectes endocrins perjudicials.
Mètodes
En aquesta tesi es van incloure 604 parelles mare-fill del projecte europeu NewGeneris, 50.651 parelles mare-fill de la cohort noruega (MOBA) i 707 parells de mares i fills dels estudis RHEA (Grècia) i Hmar (Catalunya). Les dades dietètiques es van recollir durant l'embaràs mitjançant qüestionaris de freqüència d'aliments. Tres mètodes s'han aplicat per derivar estimacions de l'exposició dietètica prenatal, ja sigui en relació als nivells de COP en la sang materna i del cordó o en els aliments. Informació sobre el naixement va ser obtinguda pels registres mèdics. Mesures de les distàncies anogenitals es van recollir i s'han utilitzat com marcadors d'efectes endocrins pertorbadors. Els determinants principals de la distància anogenital van ser avaluats i es va fer un estudi de fiabilitat de les mesures.
Resultats
En el projecte NewGeneris, una dieta alta en dioxines es caracteritza per una alta ingesta materna de carn i peix, i estava positivament relacionada amb dioxines i compostos similars a les dioxines a la sang materna. Alta adherència a una dieta alta en dioxines es va associar amb una reducció de 115 g de pes al néixer. En l'estudi Moba, es va trobar una relació de dosi-resposta inversa entre la ingesta de dioxines i PCBs durant l'embaràs i el pes en néixer. L'associació es va mantenir fins i tot per una ingesta inferior al límit de ingesta tolerable. En els estudis Rhea i Hmar, les distàncies anogenitals estan relacionades amb el pes al néixer, les mesures al naixement s’associaven amb aquestes dels primers anys de vida, i les mesures antropomètriques van ser altament fiables. Una dieta alta en greixos durant l'embaràs va ser positivament relacionada amb els COP en la sang materna i es va associar amb un 15% de reducció en la distància anogenital dels nounats.
Conclusions
La dieta durant l'embaràs pot influir en la càrrega corporal materna i fetal dels COP. L'exposició prenatal als COP, a través de la dieta materna, pot conduir a alteracions en el creixement fetal i als efectes pertorbadors endocrins, fins i tot en poblacions amb exposicions sota els límits d’ingesta estipulats.Programa de doctorat en Biomedicin
