Counseling Outcome as a Function of Counselor Nationality for American Expatriate Clients

This study tested the proposition that national similarity between counselor and client results in improved counseling outcome. Using a repeated-measures, quasi-experimental design, eight female counselors (four Turkish, four American) saw 16 volunteer, expatriate female American clients for single, individual counseling sessions. Results indicated no differences on (a) clients’ and counselors’ ratings of working alliance and of progress on goals, or (b) clients’ ratings of utilization intent as a function of counselor nationality. Irrespective of nationality, clients’ ratings of working alliance were higher than their counselors. These results echo a trend suggesting that clients’ preferences for cultural/ethnic similarity dissipate as the research methodology approximates actual counseling sessions. Additionally, local mental health service providers may be a viable resource for expatriate Americans.     

The solutions of vibration control problems using artificial neural networks

This paper introduces an alternative method artificial neural networks (ANN) used to obtain numerical solutions of mathematical models of dynamic systems, represented by ordinary differential equations (ODEs) and partial differential equations (PDEs). The proposed trial solution of differential equations (DEs) consists of two parts: The initial and boundary conditions (BCs) should be satisfied by the first part. However, the second part is not affected from initial and BCs, but it only tries to satisfy DE. This part involves a feedforward ANN containing adjustable parameters (weight and bias). The proposed solution satisfying boundary and initial condition uses a feedforward ANN with one hidden layer varying the neuron number in the hidden layer according to complexity of the considered problem. The ANN having appropriate architecture has been trained with backpropagation algorithm using an adaptive learning rate to satisfy DE. Moreover, we have, first, developed the general formula for the numerical solutions of nth-order initial-value problems by using ANN.For numerical applications, the ODEs that are the mathematical models of linear and non-linear mass-damper-spring systems and the second- and fourth-order PDEs that are the mathematical models of the control of longitudinal vibrations of rods and lateral vibrations of beams have been considered. Finally, the responses of the controlled and non-controlled systems have been obtained. The obtained results have been graphically presented and some conclusion remarks are given.     

An Alternative Method for Anatomy Training: Immersive Virtual Reality

The aim of this study was to investigate the effect of immersive three-dimensional (3D) interactive virtual reality (VR) on anatomy training in undergraduate physical therapy students. A total of 72 students were included in the study. The students were randomized into control (n = 36) and VR (n = 36) group according to the Kolb Learning Style Inventory, sex, and Purdue Spatial Visualization Test Rotations (PSVT-R). Each student completed a pre-intervention and post-intervention test, consisting of 15 multiple-choice questions. There was no significant difference between the two groups in terms of age, sex, Kolb Learning Style Inventory distribution, and the PSVT-R (P > 0.05). The post-test scores were significantly higher compared to pre-test scores in both the VR group (P < 0.001) and the control group (P < 0.001). The difference between the pre-test and post-test results was found to be significantly higher in favor of the VR group (P < 0.001). In this study, anatomy training with a 3D immersive VR system was found to be beneficial. These results suggest that VR systems can be used as an alternative method to the conventional anatomy training approach for health students.     

Educational technology research trends in Turkey from a critical perspective: An analysis of postgraduate theses

The aim of this study is to explore the research trends in the context of postgraduate programmes in the field of Educational Technology (ET) in Turkey between 1996 and 2016, and to uncover the possible factors that influence these trends from the perspective of ET faculty members. This study was informed by critical theory and employed the critical inquiry method. In the first phase, content analysis technique was used in order to explore trends in research methods and topics in theses completed in ET postgraduate programmes in Turkey. In the second phase, in-depth interviews were conducted with 11 faculty members regarding the possible influential factors. The findings of the content analysis indicated that ET research was dominated by quantitative research designs in the examined theses. Critical methods were overlooked and social, cultural, and political issues were largely silenced. The findings of the interviews showed that the factors that have been influential on ET research trends were the social impact of the research, personal interests and skills, disciplinary and departmental culture, and feasibility concerns. This study presents implications for better ET research by addressing blind spots of the field and providing suggestions for ET postgraduate students, ET scholars, policymakers and practitioners in a global context and other developing countries since the resulting trends in Turkey were found similar to international trends in the field.     

Development and validation of perceptions of online interaction scale

The aim of this study was to develop a measurement instrument which is compatible with literature, of which validity and reliability are proved with the aim of determining interaction perceived by learners in online learning environments. Accordingly, literature review was made, and outline form of the scale was formed with item pool by taking 14 expert opinions. As a result of exploratory factor analysis of data obtained from participation of 177 learners from eight different universities, it was seen that the scale consisted of 30 items and 3 dimensions. These dimensions are learner–content interaction, learner–instructor interaction and learner–learner interaction. Cronbach Alpha reliability coefficient of the whole scale was .95. Confirmatory factor analysis showed that fit indexes of the structure provided a good and acceptable fit. Based on these findings, Perceptions of Online Interaction Scale is a valid and reliable tool that may be used in measuring interaction occurring in online learning environments.     

E-government discourses: An inductive analysis

This article offers a new perspective on e-government by documenting the categories of e-government discourses, and evaluating them within a public value framework. Understanding e-government discourses is significant, since these discourses represent contested visions of e-government, and one can derive a feel for public sentiment about e-government from the discourses used in the media. The findings are accumulated through an inductive analysis of 85 newspaper articles, published during the year of 2010, in three top-selling, ideologically different, nationally circulating Turkish newspapers. In these 85 articles, 98 discourses presented by 90 policy actors are found. Five positive and four negative discourse categories and their relationships emerged from the analysis of the data. The results show that, government reform efforts shaped by the New Public Management movement and Turkey's harmonization efforts with the global political system in general, and with the European Union in particular, are influential in the presentation of e-government projects to the Turkish public through newspapers.     

Diagnostic accuracy of UriSed automated urine microscopic sediment analyzer and dipstick parameters in predicting urine culture test results

Introduction

Urinary tract infection (UTI) is one of the most common types of infection. Currently, diagnosis is primarily based on microbiologic culture, which is time- and labor-consuming. The aim of this study was to assess the diagnostic accuracy of urinalysis results from UriSed (77 Electronica, Budapest, Hungary), an automated microscopic image-based sediment analyzer, in predicting positive urine cultures.

Materials and methods:

We examined a total of 384 urine specimens from hospitalized patients and outpatients attending our hospital on the same day for urinalysis, dipstick tests and semi-quantitative urine culture. The urinalysis results were compared with those of conventional semi-quantitative urine culture.

Results:

Of 384 urinary specimens, 68 were positive for bacteriuria by culture, and were thus considered true positives. Comparison of these results with those obtained from the UriSed analyzer indicated that the analyzer had a specificity of 91.1%, a sensitivity of 47.0%, a positive predictive value (PPV) of 53.3% (95% confidence interval (CI) = 40.8–65.3), and a negative predictive value (NPV) of 88.8% (95% Cl = 85.0–91.8%). The accuracy was 83.3% when the urine leukocyte parameter was used, 76.8% when bacteriuria analysis of urinary sediment was used, and 85.1% when the bacteriuria and leukocyturia parameters were combined. The presence of nitrite was the best indicator of culture positivity (99.3% specificity) but had a negative likelihood ratio of 0.7, indicating that it was not a reliable clinical test.

Conclusions:

Although the specificity of the UriSed analyzer was within acceptable limits, the sensitivity value was low. Thus, UriSed urinalysis results do not accurately predict the outcome of culture.     

Turkish preservice science teachers’ efficacy beliefs regarding science teaching and their beliefs about classroom management

The purpose of this study was to explore Turkish preservice science teachers’ science teaching efficacy and classroom management beliefs. Data in this study were collected from a total number of 584 preservice science teachers utilizing the Science Teaching Efficacy Belief Instrument and the attitudes and beliefs on classroom control (ABCC) inventory. Data analysis indicated that preservice science teachers generally expressed positive efficacy beliefs regarding science teaching. In addition, results revealed that participants were interventionist on the instructional management dimension, whereas they favored non-interventionist style on the people management dimension of the ABCC inventory.     

Developing a Scale of Attitudes Toward Seeking Psychological Help: Validity and Reliability Analyses

The present study was conducted to develop the scale for Attitudes Toward Seeking Psychological Help (ASPH). Four dimensions of ASPH were determined by using factor analysis, which was conducted with 356 participants. The dimensions were named as confidence for getting psychological help; beliefs about the functions of psychological help; endurance against labelling, and self-disclosure. Reliability coefficient was found as satisfactory in the scale (.88) and subscales (.76, .77, .76, and .68). Test-retest reliability was .99. Validity of the scale was examined by using discriminant validity analysis and it was observed as sufficient. The results of the study showed that ASPH has an identifiable factor structure and it is a reliable and valid scale.     

Science teacher candidates’ perceptions about roles and nature of scientific models

Background: Scientific models have important roles in science and science education. For scientists, they provide a means for generating new knowledge or function as an accessible summary of scientific studies. In science education, on the other hand, they are accessible representations of abstract concepts, and are also organizational frameworks to teach and learn inaccessible facts. As being indispensable parts of learning and doing science, use of scientific models in science classes should be reinforced. At this point, uncovering pre-service science teachers’ (PSTs) understandings of scientific models are of great importance since they will design and conduct teaching situations for their students. Purpose: The study aimed to provide an answer to the research question: What understandings do PSTs possess about scientific models? Sample: The sample of the study consisted of 14 PSTs enrolled in an Elementary Science Education program in a public university in Ankara, Turkey. Design and methods: Data were collected by using an open-item instrument and semi-structured interviews, and were analyzed by using qualitative data analysis methods. Results: Findings showed that PSTs held fragmented views of models by having informed views in some aspects while having naïve views on others. That is, although they displayed a constructivist orientation by acknowledging the presence of multiple models for the same phenomenon depending on scientists’ perspectives or creativity involved in the production of scientific knowledge, PSTs also expressed logical positivist views by believing that models should be close to the real phenomena that they represent. Findings further revealed that PSTs generally conceptualized models’ materialistic uses, yet they did not think much about their theoretical and conceptual uses. It was observed that roles like reifying and visualizing were overestimated and models were dominantly characterized as three-dimensional representations. Conclusions: It is clear that PSTs, having difficulties in grasping the concept of models, would possibly have problems in planning their lessons effectively and would not develop accurate concepts in their students. These findings apparently support the need for appropriate pedagogic training of PSTs to scientifically reflect on and professionally make use of models in science classes.
