Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Patients with gastrointestinal cancer and the effectiveness of probiotics usage
Uvod:
Probiotiki so zaradi svojih koristnih učinkov za zdravje gostitelja dandanes zelo pomembni v medicini. Kakovostne klinične študije kažejo številne pozitivne učinke probiotikov tudi pri bolnikih z rakom prebavil. Z našo raziskavo smo ugotavljali, kakšna je seznanjenost s probiotiki pri bolnikih po operaciji raka prebavil pri nas in kako vpliva uporaba probiotikov na bolnikovo počutje.
Metode:
Uporabljena je bila kvantitativna metodologija. Podatke smo pridobili s pomočjo anonimnega vprašalnika, ki vsebuje 20 vprašanj zaprtega tipa. Razdeljenih je bilo 123 vprašalnikov, pravilno izpolnjenih je bilo 100. Rezultati so bili analizirani s statističnim programom IBM SPSS 26. Za testiranje hipotez smo uporabili hi kvadrat in binomski test.
Rezultati:
Večina pacientov po operaciji raka prebavil ni imela večjih težav. Na to ni vplivala uporaba probiotikov. Ugotovili smo, da preiskovanci nad 60 let bistveno slabše poznajo mehanizem in delovanje probiotikov ali pa jih sploh ne poznajo. Glede na izsledke naše raziskave pacienti največ informacij o probiotikih prejmejo preko reklam na televiziji ali internetu in zelo malo od zdravstvenih delavcev.
Razprava in sklep:
V naši raziskavi smo prišli do zaključka, da se vsi anketirani pacienti po operaciji na splošno dobro počutijo. Anketirani pacienti ob tem navajajo tudi veliko pozitivnih učinkov uživanja probiotikov. Menimo, da bi bil za boljšo ozaveščenost ljudi o probiotikih potreben sistemskih pristop za implementacijo sodobnih smernic za zdravo prehrano, ki vsebuje tudi probiotike.Introduction:
Probiotics are very important in modern medicine due to their beneficial effects on the hosts health. Qualitative clinical studies also show a number of positive effects of probiotics in patients with gastrointestinal cancer. In our study we researched the familiarity of Slovenian patients with probiotics, after their gastrointestinal cancer surgery, and how the use of probiotics affects the patient\u27s well-being.
Methods:
A quantitative methodology was applied. The data was obtained with the use of an anonymous questionnaire, containing 20 closed-ended questions. A total of 123 questionnaires were distributed, 100 were filled in correctly. The results were analysed with the IBM SPSS 26 statistical program. For the testing of the hypotheses we used the binomial and chi-squared test.
Results:
Most patients did not experience any major problems after gastrointestinal cancer surgery. This fact was not affected by the use of probiotics. We found that patients over 60 years of age are significantly less familiar with the mechanism and functions of probiotics or did not know them at all. According to the results of our research, patients receive most of their information about probiotics through advertisements on television or on the Internet, and little from healthcare professionals.
Discussion and conclusion:
In our study, we came to the conclusion that all surveyed patients feel generally well after surgery. Surveyed patients also report many positive effects of probiotics usage. We believe that in order to raise the people\u27s awareness of probiotics, a systemic approach would be needed for the implementation of modern guidelines for a healthy diet, which also includes probiotics
The influence of microbiota of kefir grains on the survival and growth of the fungus Candida albicans in milk
V zadnjih dveh desetletjih se vedno več pojavlja invazivna glivična okužba, imenovana kandidoza, ki predstavlja velik zdravstveni problem po celem svetu. Za preprečevanje in zdravljenje kandidoze je med drugim potrebna tudi pravilna prehrana, med katero lahko uvrščamo tudi kefir. Tako smo se posledično v diplomskem delu osredotočili na vpliv kefirja na rast in razmnoževanje glive Candida albicans.
Diplomsko delo je sestavljeno iz dveh delovteoretičnega in raziskovalnega. V teoretičnem delu je predstavljena gliva C. albicans ter bolezni, ki jih povzroča. Opisali smo tudi kefir in njegovo sestavo, med katero sodijo kefirna zrna in kefiran. Splošno smo opisali tudi skupino probiotikov.
V raziskovalnem diplomskem delu smo ugotavljali, kako se gliva kvasovka Candida albicans razmnožuje in raste v kulturi kefirnih zrn ali v svežem mleku. Različne koncentracije C. albicans smo gojili na Hicrome Ogye gojišču, kjer je bilo prisotno sveže mleko ali sveže mleko s kefirnimi zrni.
Na podlagi raziskovalnega dela smo potrdili hipotezo, da smo ob prisotnosti kefirnih zrn zasledili manjšo rast kolonij C. albicans kot pa v svežem mleku. Iz tega lahko sklepamo, da kefir zavira oz. omejuje rast C. albicans.In the past two decades we have been noticing an increased manifestation of an invasive yeast infection candidiasis, which presents a huge health problem all over the world. In order to prevent and heal candidiasis, we should also consider a healthy diet that includes kefir as well. Therefore, this diploma thesis focuses on the influence of kefir on the growth and reproduction of Candida albicans.
The diploma thesis consists of two parts, theoretical and empirical part. In the theoretical part, we presented the fungus C. albicans and diseases caused by it. We have also described kefir and its composition, which consists of kefir grains and kefiran. A general description of a group of probiotics is also given in that part of the diploma thesis.
In the empirical part, we investigated in what way yeasts belonging to the culture of Candida albicans reproduce and grow in the culture of kefir grains or in fresh milk. Different concentrations of species C. albicans were cultured on Hicrome Ogye medium, with a presence of fresh milk or fresh milk including kefir grains.
Based on the empirical part, we confirmed our hypothesis related to the influence of kefir on the growth of the yeast-like fungus C. albicans. In the presence of kefir grains, we detected the reduced growth of C. albicans colonies. This leads us to the conclusion that kefir prevents or inhibits the growth of C. albicans
Variations on the Author
“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
We 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
We 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
We 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
