Costs of unnecessary repeated diagnostic tests in cholecystectomy
The purpose of this study was to calculate the number, rate and cost of unnecessarily repeated tests on the patients who underwent open cholecystectomy and laparoscopic cholecystectomy and figure out the share of the unnecessarily repeated test costs in total test expenditures and total treatment expenditures. Alkaline phosphatase, alanine aminotransferase, aspartate transaminase, gamma glutamyl transferase, Total bilirubin, whole abdominal ultrasonography, upper abdominal ultrasonography, hepatobiliary ultrasonography tests, which were among the tests used in the patients who underwent cholecystectomy. The research group included 1296 patients. All records of the patients within totally 180 days of period including 90 days of pre-cholecystectomy and 90 days of post-cholecystectomy period were analysed. Necessity/Unnecessary criteria of the tests were identified in accordance with literature data, expert opinions and American Society of Anaesthesiologists Physical Status Classification scores. It was determined that unnecessary test costs consisted of 8.48% of the total test costs and 0.93% of the total treatment expenditures. This study showed that age, gender, surgical technique, and American Society of Anesthesiologists scores significantly differentiated unnecessary repeated test costs. Reducing the use of excessive health service and the related health expenditures, working to reveal its financial and medical benefits are crucial for the reimbursement agency, health service hosts and patients
Computer Anxiety in Nursing: An Investigation from Turkish Nurses
Top, Mehmet/0000-0001-9162-4238The purpose of this study was to determine and analyze levels of computer anxiety in nurses at a public university hospital in Turkey. This study investigated the dimensions of computer anxiety in terms of computer literacy, self-efficacy, physical arousal, affective feelings, positive beliefs, and negative beliefs. Moreover in this study it was aimed to analyze relationships among computer anxiety and some characteristics of nurses (age, gender etc.). This study based on Beckers and Schmidt's computer anxiety model. The Beckers and Schmidt's Computer Anxiety Scale (BSCAS) was used for data collection. BSCAS comprises six factors: computer literacy, self-efficacy, physical arousal in the presence of computers, affective feelings towards computers, positive beliefs, and negative beliefs. At the end of the data collection period, 175 nurses were received from the population. The response rate was 43.75 %. This study showed that a majority of nurses had medium levels of computer anxiety. Overall computer anxiety means score was 12.11 +/- 1.72. Computer anxiety has significant relationship with age (r=-.153; p<.05), personal computer ownership (r=.171; p<.05). The highest correlation was between overall computer anxiety and self efficacy (r=-.859), the lowest correlation was between overall computer and negative beliefs (r=-.653). Multiple regression analysis revealed that computer anxiety of nurses was predicted significantly by self efficacy, affective feelings, physical arousal, computer literacy, positive beliefs, and negative beliefs, respectively
Quality of life and oral health impact profile in Turkish dental patients
Top, Mehmet/0000-0001-9162-4238Background: OHRQoL, oral health impact assessment and QoL in oral health have become central to dental and oral health research. Researchers studying oral health problems have used OHRQoL as an outcome measure to determine the effect of treatment on QoL in health technology assessment. Aim: Here we aimed to evaluate the effect of oral health related quality of life and oral health impact dimensions on general health related quality of life. Method: Outpatients (n=527) at a public dental hospital were incorporated into the study. Data were collected using a survey, including questions addressing socio-demographic features, oral health related quality of life (Oral Health Impact Profile-14 [OHIP14] and Oral Health Related Quality of Life - United Kingdom [OHRQoL-UK]) and general health related quality of life (SF-36). Results: We found that OHIP-14, OHRQoL-UK responses significantly correlated with the physical and mental health dimensions of the SF-36. Our data will be useful for health managers and decision makers in health planning and reimbursement policies. Conclusion: The research results are expected to provide important evidence based information to health managers and decision makers in health planning, health technology assessment, and reimbursement policies.

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
Organizational trust, employee commitment and job satisfaction in Turkish hospitals: implications for public policy and health
Top, Mehmet/0000-0001-9162-4238WOS: 000498934400005PubMed ID: 31625587Background: Understanding relationships between factors that can affect organizational outcomes such as organizational trust, employee commitment and job satisfaction is important to foster healthy work conditions in organizations. Aims: This study aimed to determine the perception of Turkish physicians about organizational trust, employee commitment and job satisfaction and determine the relationships between them. Methods: A questionnaire was developed based on three standard survey instruments and given to 1679 doctors in four training and research hospitals in Istanbul, Turkey, in 2013. The Pearson correlation coefficient was calculated and regression analyses were conducted. Results: A total of 304 doctors completed the survey (18.1% response rate). Most were males (57%), over 30 years old (62%) and specialists (82%). A strong positive correlation was found among the study variables (P <= 0.001). Regression analyses indicated that organizational trust was a significant predictor of job satisfaction and commitment. Conclusions: Policy-makers need to consider implementing interventions in the health care system to improve the working conditions of current and future doctors in Turkey, in order to attract and retain them and prevent health care labour force losses
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
