“Thinking Creatively with Sounds and Words: Sounds and Images IIA” validity study in the Turkish language

Creativity, although it had existed since the existence of humanity, nowadays it is gaining more and more importance. In this process, creativity have been addressed in a variety of ways such as the studies of development on creativity and determination of the level of creativity. For this reason some scales or tests have been developed. Developed tests in a certain culture or language have reflect this culture and language’s understanding and qualifications. It is important to be done in a systematic way to test or scale adaptation studies in order to be applicable and meaningful in different culture or language.The purpose of this research is to study the validity of the Turkish language of the Test of Thinking Creatively with Sounds and Words: Sounds and Images IIA developed by Torrance and Cunnington.Language validity study was conducted in the academic year 2014-2015 by Dokuz Eylül University Buca Education Faculty Department of Foreign Language Education and Literature Faculty Department of Translation and Interpreting 4. Grade students (n=55). For the reliability and validity study, the Sounds and Images IIA Turkish form was conducted in the academic year 2014-2015 by Dokuz Eylül University, Adnan Menderes University, Muğla Sıtkı Koçman University Education Faculty Department of music Education 1.- 4. Grade students (n=276).The reliability of the test was determined through the value of Cronbach’s Alpha. The Cronbach’s Alpha value of the Sounds and Images IIA English form was determined .64, for the Sounds and Images IIA Turkish form was determined .61 [.60 ≤ α < .90]. To determine the correlation between English and Turkish forms the correlation analysis was made. The correlation was determined .81 and there is a positive significant relationship between scores [r=.81, p<.01]. There isn’t statistically significant difference between the English and Turkish form scores [t=.29, p>.01].The Sounds and Images IIA Turkish Form Cronbach’s Alpha reliability coefficient is .61, Spearman-Brown split-half reliability coefficient is .59 [.60 ≤ α < .90].

Assessment of creativity based learning environment for major instrument courses: A case study of Buca Faculty of Education, Department of Music Education

The development of the creative potential of individuals is considered to be one of the requirements of modern education. As in all areas, the development of students’ creative potential is also among the objectives of education programs in music education. The ability of music teachers to achieve this objective and create creative learning environments for their own students’ creative potential, is dependent on their training in such a learning environment.In this regard, one aim of this research is to develop a scale which can assess the creativity based learning environment for Major Instrument courses carried out within faculties of Education, Fine Arts Education, Music Education programs. The second aim is to evaluate using this scale, the creativity based learning environment for the Major Instrument courses carried out in the Buca Faculty of Education, Department of Music Education.The scale was developed as 5 point Likert scale and was applied to 528 students who were studying in the Faculty of Education, Fine Arts Education, Music Education Department in several universities during the 2012–2013 academic year. The data was analyzed with SPSS 16.0. Additionally, the LISREL 8.8 program was used for confirmatory factor analyses.After items distorting the factor structure were removed, the scale was left with 12 items. The scale’s Cronbach Alpha value was determined as .928. At the end of the confirmatory factor analysis the level of fit criteria were found to be; : 4.0; RMSEA: .07; NNFI: .98; CFI: .98; GFI: .94. The data show that the scale in general has an improved fit.The scale was applied to 72 students studying at the Buca Faculty of Education, Fine Arts Education, Music Education Department in the 2014–2015 academic year with the aim of determining the Major Instrument courses’ learning environments. The scale’s Cronbach Alpha value was determined as .948.Responses by students taking Major Instrument courses showed that lessons were carried out in creativity based ( =3.95) and positive learning environments ( =4.25) in which the students’ creativity was supported ( =3.73). With regard to the creativity based learning environment, Major Instrument Guitar courses presented the highest level ( =4.55) and Major Instrument Baglama course, the lowest ( =2.95)

Kümeleme yöntemlerinde BCO, OCO, BOCO ve OBCO algoritmalarının karşılaştırılması

Clustering is a process of dividing the objects into subgroups so that the same set of data is similar, but the data of different clusters is different. The basis of the fuzzy clustering algorithms is the C- Means families and the strongest algorithm is the Fuzzy C-means (FCM) algorithm. In this study; FCM, Possibilistic Fuzzy C-means (PFCM), Fuzzy Possibilistic C-means (FPCM) and Possibilistic C- means (PCM) algorithms are used to classify the several real data sets which are E.coli, wine and seed data sets into different clusters by MATLAB program. Also, the results of PFCM, FPCM, PCM and FCM algorithms are compared according to the classification accuracy, root mean squared error (RMSE) and mean absolute error (MAE). The results show that the PFCM and FPCM algorithms have better performance than FCM and PCM according to criteria for comparing the performances.Kümeleme, nesneleri özelliklerine göre kümelere bölme işlemidir, böylece aynı veri kümesi benzerdir, farklı kümelerin verileri farklıdır.

Location obfuscation and distance-based attacks on private trajectories: an experimental evaluation on real trajectory data sets

With the wide availability of GPS-enabled mobile devices, spatio-temporal data is being collected and stored for providing location-based services or for data analytics. Location-based advertisement, market research, and data mining are just some of the motivations for collecting spatio-temporal data. However, location data is also very sensitive since it may reveal information about the data subject such as his/her political views, religion, state of health, and various personal preferences, which is considered private information. One of the approaches to protect sensitive location data is obfuscation. In this thesis, we have implemented two location obfuscation techniques, performed an analytical and experimental study to investigate how e ective they are on a state of the art attack algorithm designed for spatio-temporal data. In the attack scenario, given a set of known trajectories, and a distance matrix composed of known pairwise distances between trajectories, adversary tries to approximate the target trajectory and then extract information about absence or presence of the trajectory in a given area. We used obfuscation techniques to hide information around predefined sensitive places such as hospitals, medical centers. We then used obfuscated data on the attack. Experimental results show that the applied obfuscation methods do not help protecting the privacy of users in sensitive areas in case of spatio-temporal trajectories that follow a regular pattern. We observed that the attack method works successfully because the obfuscation techniques do not scatter the sensitive points far enough from sensitive places and the linearity of the trajectory is preserved

Fuzzy multicriteria evaluation of health research investments

Health research and investments are expensive, and its explicit social, health and economic impacts are hard to define. There are many challenges and assumptions in defining specific returns on investment in health research. In the literature, there is no common approach to evaluate health research impacts. Single criterion methods are generally used with validated indicators to track overall outcomes or outcomes in a specific health research area. These methods have the ability of considering only one criterion at a time, which is usually the cost of the investment. A multicriteria method is proposed for taking care of many conflicting criteria of health research investments. The difficulty of measuring intangible criteria is captured by the fuzzy set theory. Fuzzy analytic hierarchy process (AHP) is used for the selection among four possible health research investment alternatives. A sensitivity analysis is made for the changes in the values of various parameters. First published online: 05 Feb 201

Rectal duplications accompanying rectovestibular fistula: Report of two cases

Rectal duplication (RD) cysts are rare congenital anomalies that can be diagnosed with the presence of another opening in the perineum. They seldom accompany anorectal malformations (ARM). Two cases of RD accompanying ARM at opposite ends of the phenotypic spectrum, are described. A 3-month-old baby and a 2-year-old girl with ARM were scheduled for posterior sagittal anorectoplasty. The infant had an orifice at the anal dimple and the other had an orifice at the vestibulum posterior to the rectovestibular fistula. The infant presented with no other anomalies whereas the older one presented with an unusual coexistence of caudal duplication and caudal regression syndromes. Perioperatively both orifices were found to be related to retrorectal cysts, and were excised. Clinicians should always be alert when dealing with complex malformations. Because these malformations have variable anatomical and clinical presentations, they can represent a diagnostic and therapeutic challenge
