Anadolu Kardiyoloji Dergisi , 2011,
Abstract: Objective: 1. Follow-up data of patients with simple transposition of great arteries (TGA) and TGA with ventricular septal defect (VSD), who had arterial switch operation (ASO) are compared. 2. Factors affecting mortality and morbidity after ASO are described.Methods: Seventy-six patients, who had an ASO between April 2007 and August 2010 were studied retrospectively. The patients with intact ventricular septum (IVS) (n=36) were in Group1, and those with VSD (n=40) in Group 2. The pre and postoperative clinical and echocardiographic variables and intensive care unit (ICU) outcomes were compared among groups using Mann-Whitney U, Pearson correlation and logistic regression tests.Results: The mean age at operation was 44.1 days, weight was 3.6±0.98 kg. Patients were followed for 15.5±11.21 months. The aortic cross-clamp (AoCC) and cardiopulmonary bypass (CPB) times were higher in patients with VSD (p=0.001, p=0.004). Patients in Group 1 had longer inotropic agent infusion (p=0.001). Length of stay in ICU was similar in two groups (p>0.05). There was no correlation between the length of stay in ICU and age, weight, CPB time, AoCC time. Aortic regurgitation was more frequent in Group 2 (p=0.02). During follow-up, 12 patients died (15.7%), and 8 patients had a revision operation (10.5%) (diaphragmatic plication in 4, pulmonary artery reconstruction in 1, recoarctation operation in 3 patients). Mortality was similar in groups (p>0.05).Conclusion: Arterial switch operation provides anatomical correction in TGA. Appropriate timing and good perioperative planning facilitates low morbidity and mortality in patients with VSD as in patients with simple TGA.
Moral Judgment: Truth, Order and Consequence  [PDF]
Magda Osman
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.65061
Abstract: Often we make snap moral judgments based on limited information. For instance upon reading a newspaper headline we very quickly decide on whether the implied outcome is good or bad. However, in situations like this we are also likely to revise our judgments when we read the main story and the conclusion of the article. One question yet to be answered is whether we adjust our moral judgments in a systematic way as we gain more details about a moral scenario. Two experiments (lab-based, online) addressed this question along with the influence of other factors on moral judgments (the origin of the moral scenario, the severity of the consequence of the scenario). Across both experiments, moral judgments were: 1) generally adjusted downwards as more information was presented; 2) more severe for headlines than the main story or the conclusion; 3) more severe for scenarios that were fabricated than real life stories; 4) more severe when the conclusion involved a severe consequence than a non-severe consequence.
Dynamic Moral Judgments and Emotions  [PDF]
Magda Osman
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.68090
Abstract: We may experience strong moral outrage when we read a news headline that describes a prohibited action, but when we gain additional information by reading the main news story, do our emotional experiences change at all, and if they do in what way do they change? In a single online study with 80 participants the aim was to examine the extent to which emotional experiences (disgust, anger) and moral judgments track changes in information about a moral scenario. The evidence from the present study suggests that we systematically adjust our moral judgments and our emotional experiences as a result of exposure to further information about the morally dubious action referred to in a moral scenario. More specifically, the way in which we adjust our moral judgments and emotions appears to be based on information signalling whether a morally dubious act is permitted or prohibited.
Behavioral Economics: Where Is It Heading?  [PDF]
Magda Osman
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.69109
Abstract: The addition of “behavioral” to economics has given rise to a highly successful field of research. But, is it just a fashionable new trend or is it here to stay? More to the point, how does it differ from its close relative psychology? To answer these questions, the present article considers what behavioral economics is, and where it started, with the aim of trying to forecast what the status of it will be in the future. In forecasting where behavioral economics might be heading, the argument proposed here is that the best clues can be found in psychological research. If, as has been proposed here, behavioral economics partners research trends in psychology, then the futures of both will almost certainly be moving in the same direction. Both are beginning to, and will start to rely on online tools/mobile phone applications to collect richer data revealing dynamic tends over long time horizons, and as technology continues to facilitate ways of looking at group behaviour online, then larger scale studies examining interactions amongst multiple groups of people will become the norm rather than the exception. More specifically this article speculates on the future research focus of researchers in behavioral economics and the extent to which this will overlap with psychological research on judgment and decision-making.
Nursing Students’ Experience with Information Literacy Skill  [PDF]

Yangtze Medicine (YM) , 2017, DOI: 10.4236/ym.2017.13016
Abstract: This study examined the searching skills and extent of usage of electronic databases by Nursing, Midwifery and Public Health Nursing students in the University of Health and Allied Science (UHAS). The focus was on forty (40) level 300 students drawn from a universe of two hundred and forty six (246) of the School of Public Health (SPH). The study used quantitative method approach and the survey instruments were questionnaire, interview and observation. The data collected were analyzed and classified into the following themes: usefulness, extent of use, determinants of use of e-databases, searching skills, and main drawbacks of learning information literacy skills (ILS). Although all the respondents strongly agreed that e-databases are indispensable for academic and professional practice, findings revealed that majority of them have low quality of searching skills and that accounts for the sparse use of the e-databases. This positive association is proven by Pearson’s chi square test (0.000). The study also established that students’ attitude, academic loads and methodology of teaching were the challenges hindering the acquisition of ILS of students. As a consequence, the study recommends that Academic librarians should intensify their education on e-databases, the development of research guides and encourages stronger collaboration with faculty members in the teaching of ILS so that student nurses would be more adept in searching for information to enhanced scholarship and professional practice.

Akdeniz M et al.
Konuralp Tip Dergisi , 2012,
Abstract: Objective: This study aims to investigate the health behavior of patients, their time and reason of encounter. Methods: 20 women and 9 males participated in this study. The survey questions with face-to-face interview technique were applied. Analysis was performed on 29 patients. In this study, individuals' complaints when first admitted to whom, when and what problems they applied to physician. If they applied physician and they are using family therapy; what is happening and why they use them, a questionnaire was applied. Results: The distribution of participants by age group 10.3% [three Male (M)] from 18 to 25 year age group, 13.7% percent [two M and two Female (F)] 26 to 35 year age group, 24.1% (seven M) 36-45 year age group, 27.5% (three M, five F) from 46 to 55 year age group, 20.6% (four M, two F) 56-65 year age group and 3.4% (one M) 66 years and older band. Looking at the level of education of participants, of 13.7% percent (n=4) didn’t finish elementary; of 51.7% percent (n=15) were elementary, of 13.7% percent (n=4), were middle’s, of 17.2% percent (n=5) were maturation’s and of 3.4% graduation’s. The majority of respondents (86.3%) stated that they didn’t use only physician’s recommended treatment. There is no statistically significant difference between men and women (p=0.636) to comply or not comply their physician’s recommendations. 34.4% of respondents do not only apply their physicians’ recommendations stated that they have used family therapy. Using family therapy in terms of, there is no significant difference between women and men (p=0.661). Conclusion: 52% of patients receiving conventional treatment stated that they have not declared it to their family physicians. 50% of the patients who have used traditional therapy were also used of CAM.
The Iterative Stein Rule Estimator of the Disturbance Variance in a Linear Regression Model When the Proxy Variables are Used
Deniz ünal,Fikri Akdeniz
Sel?uk Journal of Applied Mathematics , 2006,
Abstract: In case of the existence of the unobservable relevant regressors, a way of estimating the model is to use the proxy variables as regressors. Here we consider the estimator of the disturbance variance in a linear regression model with the proxy variables when the Stein-rule(SR) estimator of this model is used in place of the ordinary least square estimator (OLSE). Our aim is to examine the effect of the proxy variables on disturbance variance in a regression models with proxy variables. For this purpose we define the iterative SRP (SR in a linear regression model with the proxy variables) and iterative PSRP (Positive part SR in a linear regression model with the proxy variables) estimators of the disturbance variance in a regression model with proxy variable and analyze them by using MSE (Mean square error) criterion.
A New Statistical Method to Represent Speech Signals
Rafet Akdeniz,B. Siddik Yarman
Asian Journal of Information Technology , 2012,
Abstract: In this work, speech signals are modeled by means of so called the pre-defined "signature functions". The pre-defined signature functions are generated using the statistical properties of the speech signals. It has been exhibited that, with a few basic signature functions, any hearable sounds such as music and voice can be generated within a tolerable error.
