    The aim of this study is to determine science teacher candidatesÔÇÖ (PSTs) levels of associating their chemistry knowledge with daily life and to examine the relationship between these levels and their attitudes towards teaching science. The study is a descriptive study conducted through the survey method. This study was carried out with 30 PSTs in the part of science teacher education at the College of Education in their final semester. As the data collection tools, an open-ended questionnaire, which was developed by K─▒y─▒c─▒ and Aydo─čdu (2011), was applied to determine the PSTsÔÇÖ levels of associating their chemical knowledge with daily life. Also, the ÔÇťScience Teaching Attitude ScaleÔÇŁ developed by Thompson and Shringley (1986) and adapted into Turkish by ├ľzkan, Tekkaya and ├çak─▒ro─člu (2002) was used to determine PSTsÔÇÖ attitudes towards teaching science. The data obtained from the open-ended questionnaire analyzed based on the three categories that were used by Vazquez-Alanso and Manassero-Mas (1999). Findings obtained from the data showed that PSTsÔÇÖ level of associating their chemistry knowledge with daily life was low. Results of the statistical analyses showed that there was a significant relations between level of associating their chemistry knowledge with daily and their attitudes towards teaching science

    This study aimed to determine the knowledge, attitude, and practices of cattle farmers regarding zoonotic diseases in Erzurum, Turkey, where cattle-raising is the most common occupation. A cross-sectional study was conducted on 1,045 cattle farmers in Erzurum. In terms of the diseases that can be transmitted from animal to human, 69.6% of the cattle farmers had information on anthrax, 62.8% on brucellosis, 18.4% on tuberculosis, 44.9% on rabies, 32.5% on Crimean-Congo hemorrhagic fever, 8.9% on hydatid cyst, 8.0% on toxoplasmosis and 7.9% on giardiasis. The knowledge level of cattle farmers who were university graduates was 94.8%. Cattle farmers having over 100 cattle had a knowledge level of 96.7% on zoonotic diseases and their positive attitudes and practices reached 95.1% and 91.8%, respectively. The results showed that the increase in education status, size of the enterprise, and monthly income of cattle farmers was related to an increase in knowledge, attitude, and practices regarding zoonotic diseases. However, it was found that the positive knowledge and attitudes of the cattle farmers could not be transformed into positive practices evenly

    EXPLORING SEMANTIC PROSODIC AWARENESS LEVELS OF EFL LEARNERS THROUGH NEAR-SYNONYM WORDS

    Get PDF
    Near-synonyms are semantically similar words, but they are not always interchangeable, having a variety of collocational and semantic behaviours. Tertiary level EFL learnersÔÇÖ use of near synonyms demonstrates significant differences in terms of word choices. This article investigates (1) the level of semantic prosodic (SP) awareness in EFL learners, (2) the correlation between their SP awareness and English proficiency levels, (3) the ways EFL learners use semantic prosodic features in their speech and written productions and how they cope with challenges in SP and (4) the factors affecting their SP knowledge. The data were analysed quantitively and qualitatively. A proficiency test, a semantic prosody test, an open-ended questionnaire and a structured interview were used respectively. The findings reveal that learnersÔÇÖ SP knowledge correlates with language proficiency, but their awareness levels have little to do with the proficiency. One implication for the curriculum developers is that they should consider including relevant content related to the semantic prosody in syllabi so that the students will be able to create semantically relevant sentences like their native counterparts.

In such platforms, providing Electromagnetic Compatibility (EMC) among systems is difficult due to the simultaneous operation modes. Antenna mounting on an aircraft needs special attention and experience. The conducting surfaces of these aircraft seriously affect the radiation patterns of the antennas in a manner of re-radiation or cross polarization. In this study, the optimization of the electromagnetic interference induced by two on-board VHF-UHF transreceiver antennas is aimed. The continuous parameter Genetic and Memetic Algorithms are chosen for the optimization method. In the numerical analysis, the wire-grid model of the aircraft is constructed; the Method of Moments (MoM) is utilized for calculating the coupling between the antennas by using SuperNEC. In the measurement process, coupling and S-parameters are measured on a 1:10 scaled model in an anechoic chamber. The originality of this study is that it combines the MoM Computational Electromagnetics (CEM), CPGA and CPMA optimization methods for the minimization of coupling between the F-4 Phantom aircraft antennas. When applied together, it is seen that these methods solve very complex and time-consuming problem efficiently. It can be concluded the selected method is an accurate and low-cost alternative for the expensive and time-consuming measurement methods and a suitable tool for verifying the validity of the measurement results.Keywords: Electromagnetic interference, electromagnetic compatibility, the genetic algorith

    The aim of this study is to develop a scale compatible with the Nine Types Temperament Model (NTTM), which did not have any prior measurement tools to scientifically prove its reliability and validity. NTTM is created by re-evaluating the Enneagram System ÔÇôa system that defines nine personality types- used for analyzing and comprehending ego mechanisms. Nine Types Temperament Scale (NTTS) which is a self-rated instrument composed of 91 items with three-point Likert type was developed from this model and applied to 990 participants. Confirmatory factor analyses were carried out in order to evaluate whether the scale fits to the model related to the temperament model. In exploratory factor analyses of the scale eigen values of nine factors vary between 8.089 and 1.661, and represent 39.04% of the total variance. In confirmatory analyses of the scale CFI value is 0.88, GFI value is 0.845, IFI value is 0.88 and RMSEA value is 0.054. Test-retest reliability of the scale was evaluated with 46 participants. Cronbach alpha value of the whole scale is 0.75, while Cronbach alpha values for every temperament type were calculated as 0.77, 0.79, 0.68, 0.71, 0.80, 0.74, 0.71, 0.83 and 0.77 respectively. Concurrent validity was performed with Cloninger's TCI (Temperament and Character Inventory) and Akiskal's TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire Version). The types of NTTM showed significant correlations with TCI and TEMPS-A. Results of the study support that NTTS is a reliable and valid scale.Bu ├žal─▒┼čmada, benlik mekanizmalar─▒n─▒ dokuz ki┼čilik tipi ile a├ž─▒klayan Enneagram Sistemi'nin yeniden yorumlanmas─▒ ile olu┼čturulan ve g├╝n├╝m├╝zde ge├žerlik ve g├╝venirli─či bilimsel a├ž─▒dan kan─▒tlanm─▒┼č bir ├Âl├ž├╝m arac─▒ bulunmayan Dokuz Tip Miza├ž Modeli (DTMM) ile uyumlu bir ├Âl├žek geli┼čtirilmesi ama├žlanm─▒┼čt─▒r. 91 maddeden olu┼čan ve ├╝├žl├╝ Likert tipi bir ├Âz bildirim ├Âl├že─či olan Dokuz Tip Miza├ž ├ľl├že─či (DTM├ľ) 990 ├╝niversite ├Â─črencisine uygulanm─▒┼čt─▒r. ├ľl├že─če uygulanan a├ž─▒klay─▒c─▒ fakt├Âr analizlerinde dokuz fakt├Âr├╝n ├Âz de─čerleri 8.08 ve 1.66 aras─▒nda de─či┼čmekte ve toplam varyans─▒n %39.04'├╝n├╝ temsil etmektedir. ├ľl├že─čin modele uygunlu─čunu saptamak i├žin do─črulay─▒c─▒ fakt├Âr analizi uygulanm─▒┼čt─▒r. ├ľl├že─čin do─črulay─▒c─▒ fakt├Âr analizi sonu├žlar─▒na g├Âre CFI de─čeri 0.88, GFI de─čeri 0.845, IFI de─čeri 0.88 ve RMSEA de─čeri 0.054't├╝r. ├ľl├že─čin test-tekrar test g├╝venirli─či 46 kat─▒l─▒mc─▒yla s─▒nanm─▒┼čt─▒r. ├ľl├že─čin t├╝m├╝ i├žin Cronbach alfa de─čeri 0.75, tipler i├žin s─▒ras─▒yla 0.77, 0.79, 0.68, 0.71, 0.80, 0.74, 0.71, 0.83, 0.77ÔÇÖdir. ├ľl├že─čin e┼č zamanl─▒ ge├žerli─či Cloninger'in MKE (Miza├ž ve Karakter Envanteri) ve Akiskal'in TEMPSA( Temparement Evaluation of Memphis, Pisa, Paris and San Diego- Autoquestionnaire) ├Âl├žekleriyle s─▒nanm─▒┼čt─▒r.
