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

Possible Utilizations of Rainwater on the Campus of National University of Public Service Faculty of Military Sciences and Officer Training
Full text linkRainwater is usually only drained away, and is not utilized. Despite that, that the water during its natural circulation is the purest in this form. Why is it not used? Even now there are several methods developed to collect, store and use rainwater. My essays main goal is to present these applications on the campus of the National University of Public Service Faculty of Military Sciences and Officer Training.Rainwater is usually only drained away, and is not utilized.

Az ATP-szenzitív K+ -csatornák szerepe a szív iszkémiás adaptációjában hiperlipidémiában = The role of ATP-sensitive K+-channels in ischemic adaptation in hyperlipidemia
No full textAz ATP-szenzitív K+-csatornák (KATP) fontos szerepet játszanak a szívizom iszkémiás adaptációjában. Hiperlipidémiás állatmodellekben azonban az iszkémiás adaptáció elvész. Ez a jelenség valószínűleg összefüggésbe hozható a szív KATP csatornáinak megváltozott működésével, ezért a projekt célja a KATP csatornák vizsgálata volt hiperlipidémiás patkánymodellen. Megállapítottuk, hogy a KATP aktiváció normál étrendű patkányokban csökkenti az iszkémiát követő reperfúzió során az infarktusos terület nagyságát. A védő hatás specifikusan a mitokondriális KATP-re hatva is előidézhető. Ez a védő hatás mind specifikus mind nem-specifikus KATP blokkolók adásával kivédhető. A hiperlipidémiás állatok szíveiben a KATP infarktusos területet csökkentő hatása nem váltható ki. Hiperlipidémiában a KATP csatornát alkotó fehérjék expressziója nem változott, azonban a szívek ATP termelődése jelentősen csökkent, míg a laktát termelődés fokozódott. Megállapítottunk, hogy hiperlipidémiában a szív metabolikus funkciójának zavarával magyarázható az KATP csatornák infarktusos terület csökkentő hatásának elmaradása. | ATP-sensitive potassium channels (KATP) play an important role in the myocardial ischemic adaptation. In hyperlipidemic animal models the ischemic adaptation of the heart adaptation is lost possibly due to a KATP dysfunction. Therefore, the aim of this study was to investigate the cardioprotective effect of KATP opening in hiperlipidemic rat heart model. We found that KATP activation significantly decreased infarct size in normolipidemic animals after ischemia and reperfusion. This cardiopretective effect could also be induced by selective activation of the mitochondrial KATP. The cardiopretective effect could be inhibited by either a non-selective or a selective mitochondrial KATP blocker. We also found that in hiperlipidemia KATP opening failed to decrease infarct size. The expession of the KATP forming proteins did not change in the hyperlipidemic hearts, however, the ATP production significantly decreased and the lactate production increased. We can conclude that in hiperlipidemia the loss of the cardioprotective effect of KATP opening can be explained by the altered metabolism and impaired ATP production of the hiperlipidemic myocardium
