Effects of Learning Beliefs of Pre-Service Teachers at an English as a Foreign Language Certificate Program on their Practice Teaching
Turkish Online Journal of Qualitative Inquiry , 2011,
Abstract: The purpose of the current study is to explore the effects of pre-service teachers’ language learning beliefs on their practice teaching. Two randomly chosen pre-service teachers were recruited in the study (one male, one female). This research mainly adopted a qualitative approach using a structured interview, philosophy statements, field-notes during observations and the reflective journals of the participants. To explore their language learning beliefs and to determine the categories participants’ interview transcriptions were open coded. Five main categories of language learning beliefs were identified in the end of the analysis; (1) ideal English learner, (2) ideal English teacher, (3) ideal English classroom, (4) difficulties in language learning process, (5) strategies of learners to overcome difficulties. The findings of the observation checklist and reflection papers written by the participants revealed some significant effects of the language learning beliefs of pre-service teachers on their practice teaching. Briefly, the results of the study revealed that both participants’ teachings were greatly affected by their foreign language learning beliefs. However, it was also seen that some external factors created some divergences between the beliefs and practice teaching.
The Effect of Science Teacher Candidates’ Self-Efficacy towards Science Education on Academic Achievement
Journal of Kirsehir Education Faculty , 2011,
Abstract: The aim of study is to determinate the effect of self-efficacy beliefs towards science instruction on the academic achievement. In addition, it is investigated that effect of gender on self-efficacy and academic achievement. The sample of this research consist of total 127 candidates science teachers who attend II. III. IV. grades of Gazi University, Educational Faculty, Science Teaching Program on the spring semester of 2008-2009 educational period. In this study, to collect data, “System in Our Body Achievement Test” and “Science Instruction Self-efficacy Beliefs Scale” were used. The results showed that most of the science teacher candidates general achievement level and self-efficacy beliefs are not sufficient. In addition the teacher candidates general achievement level and self-efficacy beliefs do not vary according to the gender and it can be concluded that, self-efficacy beliefs predicts the academic achievement in system in our body concept positively in meaningful way.

Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2011,
Abstract: Istanbul city has experienced many strong earthquakes throughout its history and suffered extensive damage. The old Istanbul (Fatih and Eminonu districts), one of the most densely populated locations of Istanbul city, is a commercial centre and has many significant historical buildings. In this study, the data pertaining to the damage sustained by historical artifacts and structures from past earthquakes, are examined along with the soil amplification of the region, the liquefaction and slope stability risk in relation to the seismic microzonation maps which were prepared using geographic information system techniques. The relationship between soil behaviour and the damage resulting from previous earthquakes. The structural damage observed in the region was in accordance with the microzonation maps. Since the area does not have a high risk in terms of slope stability, this does not have much impact on the level of damage. However, it was found that soil amplification and partial liquefaction contributed to the damage to historical artifacts and structures.

Journal of Neurological Sciences , 2010,
Abstract: Aim: The aim of the present study is to determine the prevalence of cognitive and functional impairment which may be associated with dementia in hospitalized elderly.Methods: This survey was made as a descriptive study and conducted in 15 different inpatient clinics in a University hospital setting. The sample consisted a total of 273 patients who were available for the inclusion to the study. The data were collected by using the Socio-demographic Properties Questionnaire, Geriatric Depression Scale Short Form (GDS-SF 15), Delirium Graduated Scale (DGS), Functional Activities Questionnaire (FAQ), The Standardized Mini-Mental State Examination for educated and uneducated elderly individuals (D- SMMT).Results: The cognitive and functional decline which may be associated with dementia was designated on 91 of the 273 (33.3 %) hospitalized people. The risk of cognitive and functional decline is found to be significantly more with increasing age (p<0,01), female gender (p<0,05), having an income equivalent to expenses or less than costs (p<0,01), self-reporting forgetfulness (p<0,05) or lower education (p<0,01). Marital status (p>0,05) showed no significant relationship with the cognitive and functional decline.Conclusion: This survey results indicated that the rate of cognitive and functional impairment which may be associated with dementia in hospitalized people over 65 years of age is as high as one in every three patients, at a similar rate reported in the earlier literature. These results also showed that importance of nurses should take into consideration this ratio when planning their care and appropriate approach for this patients.

Klimik Journal , 2011,
Abstract: Objective: In this study, we aimed to determine the distribution of the genera of Gram-negative bacteria isolated from lower respiratory tracts of patients treated as in-patients and to calculate the antibiotic resistance rates to guide empirical antibiotic therapy. Methods: Samples taken from the lower respiratory tract and sent to the Bacteriology Laboratory at the Celal Bayar University Faculty of Medicine from January 2008 to December 2010 were retrospectively analyzed. Results: A total of 853 Gram-negative bacteria were isolated from specimens of in-patients. The rates of carbapenem (85%) and multidrug resistance (47%) among A. baumannii were higher than those observed for P. aeruginosa (30% and 19.2%). Carbapenem resistance was not found among the bacteria of the family Enterobacteriaceae, while the highest rates of resistance were detected for ciprofloxacin and trimethoprim-sulfamethoxazole.Conclusions: Implementation of effective treatment protocols based on sensitivity test results can be useful in preventing nosocomial lower respiratory infections caused by resistant Gram-negative bacteria.

Pembe KESK?NO?LU,Reyhan U?KU,Grsev YENER
Journal of Neurological Sciences , 2008,
Abstract: Aim. To examine the Turkish version of Standardized Mini Mental State Examination (SMMSE) that some items were revised in the community dwelling elderly population as a pretest.Methods. The revised SMMSE that some items such as orientation to time, orientation to place, phrase construction, phrase repeatition and figure copying were changed according to educated and less educated older persons separately, was examined in 58 elderly aged 65 years and over to be pretest.Results. Of the totally 58 elder subjects, 27 were educated 5 years and over, while 31 elderly were less educated, and mean age was 70.8 years. The total score, the scores of orientation to time and attention-calculation were significantly higher in the educated elderly. The score of recall was the lowest in both educated and less educated groups.Conclusion. The revised SMMSE was a more understandable and more simple administrable test for educated and less educated elderly individuals. However, the reliability and validity of the revised test should be done.

Journal of Neurological Sciences , 2011,
Abstract: Alzheimer disease is a progressive disorder and leading to decrease in cognition, and functional capacity. There are several reports on the relationship between motor function and cognitive impairment in healthy elderly. And also the relationship between depressive and cognitive status has been discussed before. We hypothesized that physical performance is related to cognitive deficits and aimed to examine the relationship between cognition, physical status and depression in this study. The study consisted of 26 patients with probable Alzheimer type of dementia (21 female, 5 male) according to NINCDS-ADRDA criteria, who were admitted to Dokuz Eylul University Dementia outpatient clinic. The Physical Performance Test (PPT), the Mini-Mental State Examination (MMSE), the Stroop Test, the Yesavage Geriatric Depression Scale (YGDS), and the Instrumental Activities of Daily Living Scale (IADL) were used to evaluate the physical, depressive and cognitive status. We found significant weak to moderate correlations between PPT and cognitive tests [(the Stroop test; time to identify the colors of words (r: 0.5152 p: 0.012)], and MMSE [(r: 0.5564 p: 0.006)], and also YGDS (r: - 0.4304 p: 0.040) after corrected with age, gender and education status (p<0.05). At the end of this study, it has been concluded that the Stroop test is more sensitive tool showing the correlation to depression and physical functions. Also, we believe a comprehensive therapeutic strategy should be designed in coping with physical and cognitive disability.

Journal of Neurological Sciences , 2009,
Abstract: Aim: The study was methodically carried out to examine validity and reliability of Turkish form of “Caregiver Burden Inventory” Methods: Sampling group of the study included 230 primary caregiver of dementia patients. Data was collected using Caregiver Burden Inventory which has 24 items was developed by Novak and Guest in 1989. Forward and backward translation procedure and pretest was made to establish translation equivalency and linguistic adaptation. In order to estimate instrument stability between different occasions test-retest reliability was performed. To determine the internal consistency for the inventory, Coefficient Alpha was obtained. The scale was examined by 10 experts to verify it's contend validity. Construct validity was established by hypothesis testing and factor analysis.Results: Expert opinions were consulted regarding the scope validity of the CBI. The CBI showed very high internal consistency (Cronbah alpha value 0.94). Confirmatory factor analyses demostrated that model was well fit. There was a strong and linear correlations between test-retest measures (r=0.98). In the item analysis it has seen that the item-total correlation coefficients of scale ranged from 0.52- to 0.84 and none of the items of scale was deleted. All of the factors of the inventory positively correlated with Beck Depression Inventory scores (r ranged from 0.47-0.71)Conclusion: As a result it has found that “Caregiver Burden Inventory” was a sufficiently valid and reliable instrument in Turkey.
Comparative Evaluation of Community Detection Algorithms: A Topological Approach
Günce Orman,Vincent Labatut,Hocine Cherifi
Computer Science , 2012, DOI: 10.1088/1742-5468/2012/08/P08001
Abstract: Community detection is one of the most active fields in complex networks analysis, due to its potential value in practical applications. Many works inspired by different paradigms are devoted to the development of algorithmic solutions allowing to reveal the network structure in such cohesive subgroups. Comparative studies reported in the literature usually rely on a performance measure considering the community structure as a partition (Rand Index, Normalized Mutual information, etc.). However, this type of comparison neglects the topological properties of the communities. In this article, we present a comprehensive comparative study of a representative set of community detection methods, in which we adopt both types of evaluation. Community-oriented topological measures are used to qualify the communities and evaluate their deviation from the reference structure. In order to mimic real-world systems, we use artificially generated realistic networks. It turns out there is no equivalence between both approaches: a high performance does not necessarily correspond to correct topological properties, and vice-versa. They can therefore be considered as complementary, and we recommend applying both of them in order to perform a complete and accurate assessment.
