Full text linkChronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. COPD is frequently associated with comorbidities, the most common complication being pulmonary hypertension and subsequent right heart failure. The prevalence of pulmonary hypertension and the pathophysiological processes of its installation in patients with COPD remain insufficiently studied, although it is known that its share increases with the severity of COPD, and its rate has been reported ranging from 20% to 90%. in the article, the author summarizes the notorious international discoveries and local contributions in this field, elucidating the opportunities, challenges and perspectives of studying the problem. Multiple investigations conducted in the last three decades by local researchers have deepened the knowledge of the pathophysiology, clinic, diagnosis, treatment and prophylaxis of pulmonary hemodynamic and cardiac function disorders in patients with COPD. Further investigations in this area are neededBronhopneumopatia obstructivă cronică (BPOC) reprezintă una dintre principalele cauze ale morbidităţii şi mortalităţii la nivel mondial. BPOC este frecvent asociată cu comorbidităţi, complicaţia cea mai frecvent întâlnită fiind hipertensiunea pulmonară şi insuficienţa cardiacă dreaptă ulterioară. Prevalenţa hipertensiunii pulmonare şi procesele fiziopatologice de instalare a ei la pacienţii cu BPOC rămân studiate insuficient, deşi se cunoaşte că ponderea ei creşte odată cu severitatea BPOC, iar rata sa a fost raportată variind de la 20% la 90%. În articol, autorul sintetizează descoperirile notorii internaţionale şi contribuţiile autohtone în acest domeniu, elucidând oportunităţile, provocările şi perspectivele de studiere a problemei. Multiplele investigaţii efectuate în ultimele trei decenii de cercetătorii autohtoni au permis aprofundarea cunoştinţelor fiziopatologiei, clinicii, diagnosticului, tratamentului şi profilaxiei dereglărilor hemodinamicii pulmonare şi funcţiei cardiace la pacienţii cu BPOC. Este necesară continuarea investigaţiilor în acest domeniuХроническая обструктивная болезнь легких (ХОБЛ) является одной из ведущих причин заболеваемости и смертности во всем мире. ХОБЛ часто сопровождается сопутствующими заболеваниями, а наиболее частым осложнением является легочная гипертензия и последующая правожелудочковая недостаточность. Распространенность легочной гипертензии и патофизиологические процессы ее возникновения у пациентов с ХОБЛ остаются недостаточно изученными, хотя известно, что ее доля увеличивается одновременно с тяжестью ХОБЛ, и ее частота, по сообщениям, колеблется от 20% до 90%. В статье автор обобщает известные международные открытия и вклад отечественных ученных в этой области, освещая возможности, проблемы и перспективы изучения вопроса. Множественные научные изыскания, проведенные за последние три десятилетия местными исследователями, углубили знания о патофизиологии, клинике, диагностике, лечении и профилактике нарушений легочной гемодинамики и сердечной функции у пациентов с ХОБЛ. Необходимы дальнейшие исследования в этой област
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
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
