The Adaptation of Emotional Autonomy Scale into Turkish and Examinatıon of Emotional Autonomy an Non-Clinical Adolescence Sample

Bu çalışmada Duygusal Özerklik Ölçeği'nin (DÖÖ) doğrulayıcı faktör analizi ve madde cevap kuramı kullanımı ile Türkçe’ye uyarlanması ve psikometrik özelliklerinin incelenmesi amaçlanmıştır. Materyal ve Metot: Çalışma, İzmir’de farklı sosyodemografik özelliklere sahip dört lisedeki 14-20 yaş arasındaki 600’ü kız, 445’i erkek ve altısı cinsiyet belirtmemiş toplam 1,051 öğrenci ile gerçekleştirilmiştir. Çalışmada veri toplam aracı olarak DÖÖ ve Ana-Baba ve Ergen İlişki Envanteri kullanılmıştır. 20 maddeli DÖÖ, ebeveyni idealleştirmeme, ebeveyne bağımlı olmama, ebeveyni insan olarak algılama ve bireyleşme alt ölçeklerini kapsamaktadır. Bulgular: Ölçeğin içtutarlık katsayısı 0,78 ve Guttman iki yarım test güvenirliği 0,79, üç hafta arayla yapılan test-tekrar test güvenirlik katsayısı 0,65 olarak bulunmuştur. Madde cevap kuramı ile yapılan analizlerde 1, 2, 4, 9, 11 ve 18 numaralı maddelerde iki parametreli modele uyumu gözlenmiştir. 3, 8, 10, 14, 16 ve 19 numaralı maddeler en düşük seviyede madde ayırt ediciliği, 7, 17 ve 18. maddeler düşük, 6, 8 ve 10. maddeler yüksek madde güçlük düzeyi göstermişlerdir. Ölçeğin dört faktörlü yapısının test edildiği Doğrulayıcı Faktör Analizi sonucunda iyi uyum katsayısı 0,81 olarak elde edilmiştir. Ölçeğin Ana-Baba ve Ergen İlişki Envanteri Genel Anlaşmazlık ve Bütünlük alt ölçekleri ile bağıntı düzeyi sırasıyla 0,55 ve 0,48 bulunmuştur. Sonuç: Madde cevap kuramı ile yapılan analizler bu ölçek yapısının bazı sorunlu yönlerini göstermiştir. Bu sonuç, duygusal özerkliğin çok boyutlu doğasından kaynaklanmaktadır. Bu nedenle ileride duygusal özerkliğin belirleyicileri ve sonuçlarına ilişkin yapılacak çalışmalarda çok boyutlu yapısı dikkate alınmalıdır. Bazı sınırlılıklara karşın, geniş bir Türk öğrenci örnekleminde yapılan derinlemesine yapısal analizler, DÖÖ’nün kullanışlı olduğunu göstermiştir.The study is aimed to adapt the Emotional Autonomy Scale (EAS; Steinberg & Silverberg, 1986) to Turkish through the use of confirmatory factor analysis and item response theory, and to examine the psychometric characteristics of the scale. Material and Method: The study was done among 1,051 students (600 girls, 445 boys, 6 not identified sexuality; aged 14-20) in four high schools from different socioeconomic levels in İzmir. In the study, the Turkish form of the EAS and the Parent-Adolescent Relationship Questionnaire (PARQ) were used as data collection tools. Emotional Autonomy was measured by 20-item EAS, which included deidealization, nondependency on parents, perceives parents as people, and individuation subscales. Results: The internal consistency coefficient was 0.78 and the Guttman split-half coefficient was 0.79. The test-retest reliability by three weeks was 0.65. The analysis of items by item-response theory indicated that the six items (item 1, 2, 4, 9, 11, and 18) represented a good fit to the two-parameter model fit. The analysis of items by item response theory indicated that item 3, 8, 10, 14, 16 and 19 to be the least discriminant item, and consecutively item 7, 17 and 18 followed. The most discriminant items happened to be 6, 8, and 10. The four factor structure of the scale was tested and the Goodness of Fit Index was 0.81 through confirmatory factor analysis. The correlation coefficients between the EAS total score, and the PARQ Global Distress and Cohesion Subscales were 0.55 and -0.48 respectively. Conclusion: The analysis of items by item-response theory showed some problematic aspects of the construction of this scale. This result is due to the fact the emotional autonomy is very likely to be multidimensional in nature. Therefore, in future studies of predictors and outcomes of the emotional autonomy, multidimensionality should be taken into account. Despite some limitations, an in-depth structural analysis of the EAS in a large sample of Turkish students indicates that it is possible to give a useful interpretation to the EAS

Initial Psychometric Evaluation of the Physical Health Attitude Scale and a Survey of Mental Health Nurses

INTRODUCTION: Nurses play an important role in improving the physical health of individuals with serious mental illnesses. The literature on the attitudes of mental health nurses towards physical healthcare provides a small amount of data. Assessing trends in nurses' attitudes through suitable surveys is important to ensure holistic care. AIM/QUESTION: This study sought to examine the Turkish version of the Physical Health Attitude Scale's (PHASe) validity and reliability and to survey Turkish mental health nurses' attitudes towards physical healthcare. METHOD: The sample consisted of 174 nurses working in acute psychiatric wards. Firstly, the psychometric properties of the scale were analyzed using factor analysis and measures of internal consistency and reliability. Then, the survey results of the attitudes of mental health nurses towards the physical health of patients with serious mental illnesses were determined using the Physical Health Attitude Scale (PHASe). RESULTS: The translated PHASe scale functioned best as a 24-item version and 4-factor solution that explains 51.3% of the variance. The internal consistency value was .83. The respondents' attitudes were generally positive about their role. There was less agreement for the involvement of nurses in practices of health promotion, such as sexual health, eye and/or dental examinations. The nurses surveyed also tended to use smoking for therapeutic purposes. IMPLICATIONS FOR PRACTICE: Mental health nurses' knowledge and attitudes should be enhanced by additional training in the ways of meeting patients' biopsychosocial needs. Obstacles to physical healthcare can be removed by implementing standard protocols nationwide. This article is protected by copyright. All rights reserved

A comparative study on the effects of a pesticide (cypermethrin) and two metals (copper, lead) to serum biochemistry of Nile tilapia, Oreochromis niloticus

The present study was designed to compare the responses in freshwater fish Oreochromis niloticus exposed to a synthetic pyrethroid, cypermethrin (CYP); an essential metal, copper (Cu); and a nonessential metal, lead (Pb). Fish were exposed to 0.05 μg/l CYP, 0.05 mg/l Cu, and 0.05 mg/l Pb for 4 and 21 days, and the alterations in serum enzyme activities, metabolite, and ion levels were determined. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities increased in response to CYP, Cu, and Pb exposures at both exposure periods. While elevations in alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) activities and in cholesterol level were observed in pesticide-exposed fish at 4 and 21 days, they increased in Cu- and Pb-exposed fish at 21 days. Although metal-exposed fish showed increases in cortisol and glucose levels at 4 days followed by a return to control levels at the end of the exposure period, their levels elevated in pesticide-exposed fish at both exposure periods. Total protein levels decreased in Pb- and pesticide-exposed fish at 21 days. Na+ and Cl− levels decreased in pesticide-exposed fish at both exposure periods and in Cu- and Pb-exposed fish at 21 days. The exposures of pesticide and metals caused an elevation in K+ level at the end of the exposure period. The present study showed that observed alterations in all serum biochemical parameters of fish-treated pesticide were higher than those in fish exposed to metals

Effect of curing time on selected properties of soil stabilized with fly ash, marble dust and waste sand for road sub-base materials

The properties of sub-base filling materials in highway construction are essential, as they can determine the performance of the road in service. Normally, the existing materials are removed and replaced with new materials that have adequate load-bearing capacity. Rising environmental concern and new environmental legislations have made construction professionals consider other methods. These methods include stabilizing the existing materials with other additives to improve their performance. Additives can be waste materials generated by different industries. In this work, the existing excavated soil is stabilized with waste materials. The wastes consisted of fly ash, marble dust and waste sand. The percentage addition of waste materials was 5%, 10%, 15% and 20% (by mass) of the existing soil. The soil/waste specimens were cured for 1, 7, 28, 56, 90 and 112 days before testing. Testing included the dry unit weight and unconfined compressive strength ( qu) as well as X-ray diffraction analysis and scanning electron microscopy observation. Also, the California Bearing Ratio values were obtained and are reported in this investigation. The results showed that the qu values increased with the increase in waste materials content. Also, there is tendency for the dry unit weight to increase with the increase in waste materials

A high-performance 8 nV/root Hz 8-channel wearable and wireless system for real-time monitoring of bioelectrical signals

Background: It is widely accepted by the scientific community that bioelectrical signals, which can be used for the identification of neurophysiological biomarkers indicative of a diseased or pathological state, could direct patient treatment towards more effective therapeutic strategies. However, the design and realisation of an instrument that can precisely record weak bioelectrical signals in the presence of strong interference stemming from a noisy clinical environment is one of the most difficult challenges associated with the strategy of monitoring bioelectrical signals for diagnostic purposes. Moreover, since patients often have to cope with the problem of limited mobility being connected to bulky and mains-powered instruments, there is a growing demand for small-sized, high-performance and ambulatory biopotential acquisition systems in the Intensive Care Unit (ICU) and in High-dependency wards. Finally, to the best of our knowledge, there are no commercial, small, battery-powered, wearable and wireless recording-only instruments that claim the capability of recording electrocorticographic (ECoG) signals. Methods: To address this problem, we designed and developed a low-noise (8 nV/√Hz), eight-channel, battery-powered, wearable and wireless instrument (55 × 80 mm2). The performance of the realised instrument was assessed by conducting both ex vivo and in vivo experiments. Results: To provide ex vivo proof-of-function, a wide variety of high-quality bioelectrical signal recordings are reported, including electroencephalographic (EEG), electromyographic (EMG), electrocardiographic (ECG), acceleration signals, and muscle fasciculations. Low-noise in vivo recordings of weak local field potentials (LFPs), which were wirelessly acquired in real time using segmented deep brain stimulation (DBS) electrodes implanted in the thalamus of a non-human primate, are also presented. Conclusions: The combination of desirable features and capabilities of this instrument, namely its small size (~one business card), its enhanced recording capabilities, its increased processing capabilities, its manufacturability (since it was designed using discrete off-the-shelf components), the wide bandwidth it offers (0.5 – 500 Hz) and the plurality of bioelectrical signals it can precisely record, render it a versatile and reliable tool to be utilized in a wide range of applications and environments

Hyperbolic three-string vertex

Abstract We begin developing tools to compute off-shell string amplitudes with the recently proposed hyperbolic string vertices of Costello and Zwiebach. Exploiting the relation between a boundary value problem for Liouville’s equation and a monodromy problem for a Fuchsian equation, we construct the local coordinates around the punctures for the generalized hyperbolic three-string vertex and investigate their various limits. This vertex corresponds to the general pants diagram with three boundary geodesics of unequal lengths. We derive the conservation laws associated with such vertex and perform sample computations. We note the relevance of our construction to the calculations of the higher-order string vertices using the pants decomposition of hyperbolic Riemann surfaces

A Glance At The Relation Of Human, Place And Building Out Of The Phenomenon Of Mobility In Architecture

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2006Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2006Mobil mimarlık diye bir alanın varlığın iddia etmeyi olanaklı kılan -ve onu böyle ilgi çekici hale getiren- mimarlık ürününün ağır, durağan ve kalıcı olan baskın imgesidir. Buradan yola çıkarak bu çalışma mimarlıkta mobilite kavramını bir çerçeve olarak alır ve onunla insan yerleşmesine ve yapılı çevreye bakmayı dener. Yapıyla yer arasındaki bir takım ‘sıradan’ ilişkileri deşifre etmeye çalışır. Endüstrileşme, kapitalizm ve modern mimarlıkla birlikte insanın çevresiyle ilişkisinin zayıfladığı tespiti üzerine geliştirilen ‘yersizleşme’ söylemi mimarlık alanında kayda değer bir yere sahiptir: Mekanla girilen ilişki anlamdan boşaltılmış; yapılar soyut bir ‘hiçbiryerde’ inşa edilmeye başlanmış; bu çevrelerde yaşayan insanlar da yersiz yurtsuz göçebelere hatta şizofrenlere dönüşmüşlerdir. Bu çalışma, mobil mimarlığı bu süreçlerle ilişkilendirmeyi dener. Onu ‘yerleşik’ değerlerin dışında, daha sorgulanmış bir yasam için bir mimarlık önerisi olarak ortaya koyar. Göçebeliğin olumlu vurgusu ve belki de mobil mimari düzeneklerin ‘olay’ üzerine kurulu varlıkları insanlar için daha özgür bir yaşantının, daha insancıl ilişkilerin kurulmasına yardımcı olabilir.Actually, which makes feasible to affirm the presence of Mobile Architecture -and makes it attractive- is nothing but the dominant image of architecture which is massive, stagnant and permanent. Therefore this study is an attempt to take a glance to settlement of human and designed environment via the frame of “mobility” concept in architecture. It takes “place” as context rather than “a part of soil/ground” and transcribes the very ‘ordinary’ connections between the place and the man made construction. The discourse of “Loss of place” which is based on the idea that, industrialization, capitalism and modern architecture weakened the bonds of humans with environment is an appreciable one in the field of architecture: The space has lost its meanings ; the buildings has been constructed on abstract ‘nowhere’s; people who are doomed to live in such nowheres turn out to be nomads with the symptoms of schizophrenia. This study aims to relate mobile architecture to the vision and concepts depicted till now. It puts forward the ‘mobile architecture’ as a suggestion in a more interrogated way of life out of the common settled values. The positive accent of Nomadic life and the contrivances of mobile architecture based on “happening” may help to open a gateway for a more independent and humanistic lives for people.Yüksek LisansM.Sc

Hemodynamics of patient-specific aorta-pulmonary shunt configurations

Optimal hemodynamics in aorta-pulmonary shunt reconstruction is essential for improved post-operative recovery of the newborn congenital heart disease patient. However, prior to in vivo execution, the prediction of post-operative hemodynamics is extremely challenging due to the interplay of multiple confounding physiological factors. It is hypothesized that the post-operative performance of the surgical shunt can be predicted through computational blood flow simulations that consider patient size, shunt configuration, cardiac output and the complex three-dimensional disease anatomy. Utilizing only the routine patient-specific pre-surgery clinical data sets, we demonstrated an intelligent decision-making process for a real patient having pulmonary artery atresia and ventricular septal defect. For this patient, a total of 12 customized candidate shunt configurations are contemplated and reconstructed virtually using a sketch-based computer-aided anatomical editing tool. Candidate shunt configurations are evaluated based on the parameters that are computed from the flow simulations, which include 3D flow complexity, outlet flow splits, shunt patency, coronary perfusion and energy loss. Our results showed that the modified Blalock-Taussig (mBT) shunt has 12% higher right pulmonary artery (RPA) and 40% lower left pulmonary artery (LPA) flow compared to the central shunt configuration. Also, the RPA flow regime is distinct from the LPA, creating an uneven flow split at the pulmonary arteries. For all three shunt sizes, right mBT innominate and central configurations cause higher pulmonary artery (PA) flow and lower coronary artery pressure than right and left mBT subclavian configurations. While there is a trade-off between energy loss, flow split and coronary artery pressure, overall, the mBT shunts provide sufficient PA perfusion with higher coronary artery pressures and could be preferred for similar patients having PA overflow risk. Central shunts would be preferred otherwise particularly for cases with very low PA overflow risk
