Equity in the Turkish education system: A multilevel analysis of social background influences on the mathematics performance of 15-year-old students

Ozdemir, Caner

Makale | 2016 | EUROPEAN EDUCATIONAL RESEARCH JOURNAL15 ( 2 ) , pp.193 - 217

This paper aims to discover the level of equity in the Turkish education system using maths outcomes of 15-year-old students in the Programme for International Student Assessment (PISA) exam. In order to do that, associations between various social background variables and student performance are analysed via multilevel models. Female pupils, students from lower socio-economic backgrounds and students from eastern regions are all found to be disadvantaged in terms of maths outcomes. The biggest gap between students in Turkey is due to school types. The difference between selective academic schools and other types of schools is more . . .than 100 points, which is equal to the difference between almost four grade years. However, the positive effect of attending selective academic schools is smaller for girls. Further investigations indicate that, in the Turkish education system, school type at secondary level represents the effects of socio-economic background and educational and physical resources at school in addition to previous achievements of pupils. Results of the analyses show that it is very hard to claim that the education system in Turkey is operating in a way that mitigates existing inequalities in the society. To the contrary, there are indications that the Turkish education system itself reproduces inequalities Daha fazlası Daha az

We report a new species of Spermophilus ( Rodentia: Sciuridae), here designated as S. torosensis sp. nov., distributed in the Taurus Mountains in southern Anatolia, Turkey. A total of 161 specimens of the genus Spermophilus from Turkey and Iran were analyzed for their morphological, morphometric, and karyological characteristics. Uni- and multi-variate statistical analyses of morphologic data for 95 adult specimens yielded 4 distinct groups. Taxonomic evaluations classified the specimens into 4 species Spermophilus citellus, S. xanthopymnus, S. fulvus and S. torosensis sp. nov. Morphometrics, coat coloration, a brush-shaped tail, an . . .d a NFa value of 72 are diagnostic characters that distinguish S. torosensis sp. nov. from the other species. In Turkey, S. torosensis sp. nov. was found in 6 locations. The karyotype of S. fulvus also is described for the first time as 2n= 36, NFa= 70 and NFa= 66; new karyotypic data is reported for S. xanthoprymnus from Iran and Turkey Daha fazlası Daha az

Introduction: We aimed to describe the treatment outcomes in patients with bacteriologically confirmed pulmonary tuberculosis (PTB) and identify factors associated with successful treatment outcome. Methodology: The medical charts of patients with smear and/or culture-positive PTB who were treated between 2005 and 2011 at the Kocaeli Tuberculosis Dispensary, Turkey, were reviewed. Patients were categorized as having a successful (cured or with a completed treatment) or poor (treatment default, treatment failure, death) treatment outcome. The association of demographic and clinical factors, including gender, age, education, occupatio . . .n, insurance, family size, living area, smear and culture positivity, retreatment, comorbidity, drug resistance, and cavity on radiography, with the success of treatment, was evaluated by univariate and multivariate analyses. Results: Of 738 patients (258 females, 480 males) with bacteriologically confirmed PTB, 683 (92.6%) had successful treatment outcomes. Of those with a poor outcome, 29 (3.9%) had treatment default, 18 (2.4%) died, and 8 (1.1%) had treatment failure. Young age, no previous treatment, no comorbidity, no drug resistance, and high education level were factors significantly associated with successful PTB treatment outcome (p < 0.05 for all). Conclusions: Treatment outcome was successful in young and educated PTB patients who had drug resistance, previous treatment history, and no comorbidities. Knowledge of the factors affecting treatment success will lead to the undertaking of specific measures in the management of PTB, which may help to decrease treatment failure Daha fazlası Daha az

Chronic abdominal pain sometimes constitute a major challenge, specially when a patient has two diseases with dominant features of abdominal pain in both. At this point, clinicians face a daunting task both in diagnosing and treating an individual’s chronic abdominal pain. Similarly, familial Mediterranean fever disease and Crohn's disease have the same clinical features in terms of chronic abdominal pain, and inflammatory properties of these diseases. The association of familial Mediterranean fever disease and Crohn’s disease is very rare and may lead to a remarkable challenge in both diagnosis and treatment. Here, we report a youn . . .g man with FMF disease presented with extraordinary and intolerable abdominal pain relieved only by excessive narcotic analgesics. The presented case was diagnosed with CD and successfully treated with anti-TNF (tumor necrosis factor) due to steroid refractory. © 2016, Academy of Medical Sciences of I.R. Iran.

Hydropower potential of municipal water supply dams in Turkey: A case study in Ulutan Dam

Kucukali S.

Makale | 2010 | Energy Policy38 ( 11 ) , pp.6534 - 6539

This paper aims to analyze the hydropower potential of municipal water supply dams in Turkey. The facility is in favor with the energy policy of Turkish Government and European Union. In the study, the design head of the power plant was selected as the average water level of the reservoir and the discharge was calculated from the annual water supply of the dam. It has been estimated that the existing 45 municipal water supply dams of Turkey have an electric energy potential of 173GWh/year, corresponding to about 24,000,000 Euro/year economic benefit. The financing of these facilities can be provided from international funding instit . . .utions. For a case study, Zonguldak Ulutan Dam and its water treatment plant have been investigated in detail. The current electricity consumption of the water treatment plant is 4,500,000kWh/year and the facility provides 35,000m 3/day water to 6 settlements. The installation of a hydropower plant on the mentioned water treatment plant will cut the electric consumption by 24%. The proposed project has a payback period of 1.4 years and it can produce clean and feasible energy. © 2010 Elsevier Ltd Daha fazlası Daha az

Mole rats have adapted to living underground and have a wide range chromosomal variation in Turkey, ranging between 2n = 36 and 2n = 60. This study was performed on the subterranean mole rats of the Nannospalax nehringi (Nehring, 1898), sampled around Cankiri and corum provinces in central Anatolia, and the karyotypes of 91 specimens across 38 localities were analyzed. Different chromosomal forms that have the same 2n values were assigned letters according to their geographic locations in Turkey: C for central forms, N for northern forms, S for southern forms, E for eastern forms, and W for western forms. It was determined that N. n . . .ehring has 2n = 54C, NF = 74; 2n = 56N, NF = 72; 2n = 58N, NF = 74, and 2 different forms of 2n = 60 (NF = 78, NF = 82) in these areas. This study filled the gaps in distribution of blind mole rat chromosomal forms around Cankiri and Corum provinces. The distribution areas of 2n = 54C, 56N, 58N, and 60 forms in the area were brought to light Daha fazlası Daha az

Background and Design: Albeit an easily recognized disease, urticaria features many diverse approaches which rationalize the need for an algorithm for the diagnosis, classification, etiopathogenesis, diagnostic evaluation and therapeutic approach. Therefore, authors from Dermatoallergy Working Group of the Turkish Society of Dermatology and the Turkish Dermatoimmunology and Allergy Association aimed to create an urticaria guideline for the diagnosis, treatment and followup of urticaria. Materials and Methods: Each section of the guideline has been written by a different author. The prepared sections were evaluated in part by e-mail . . .correspondence and have taken its final form after revision in the last meeting held by the participation of all authors. Results: The guideline includes the description, classification, pathophysiology as well as diagnosis and treatment of urticaria. Urticaria is classified into two main types: acute urticaria and chronic urticaria while chronic urticaria is further subdivided into spontaneous urticaria and inducible urticaria. The first step of treatment includes standard doses of H1-blockers. In patients who do not respond to the first step, antihistamine dose is increased up to four times; if unsuccessful, another second-generation antihistamine is given in the same dose. In antihistamine-resistant cases, introduction of omalizumab is required. Omalizumab dose may be increased in patients failing to respond to the standard dose. In patients unresponsive to omalizumab, cyclosporine-A may be given. Routine diagnostic tests are not recommended in acute urticaria. In chronic urticaria, erythrocyte sedimentation rate, differential blood count and C-reactive protein testing are the only investigations that are needed routinely. Conclusion: Chronic urticaria is a disease that can be challenging for the physician in terms of treatment and follow-up. Depending on evidence-based data (and individual experiences), this guideline will have a leading role in the diagnosis and treatment of urticaria and help the physician to overcome the challenges in the management Daha fazlası Daha az

Macrofloral Biostratigraphy of the Upper Bashkirian Kozlu Formation, Zonguldak Coalfield, North Turkey

Cleal, Christopher | Stolle, Ellen | van Waveren, Isabel | King, Sarah | Didari, Vedat


The macrofloras of the Kozlu Formation of the Zonguldak Coalfield (north Turkey) belong to the Lyginopteris hoeninghausii Zone and thus indicate a Langsettian (early Westphalian/late Bashkirian) age. The macrofloral evidence indicates the lower part of the zone (Neuralethopteris jongmansii Subzone) and thus an early Langsettian age, whereas palynological biostratigraphy indicates that upper Langsettian deposits are also present.

Airborne particulate matter (PM2.5 and PM10) concentrations were measured in Zonguldak, Turkey from January to December 2007, using dichotomous Partisol 2025 sampler. Collected particulate matter was analyzed for 14 selected polycyclic aromatic hydrocarbons (PAHs) by high-performance liquid chromatography with fluorescence detection (HPLC-FL). The seasonal variations of PM2.5 and PM10 concentrations were investigated together with their relationships with meteorological parameters. The maximum daily concentrations of PM2.5 and PM10 reached 83.3 µg m-3 and 116.7 µg m-3 in winter, whereas in summer, they reached 32.4 µg m-3 and 66.7 µ . . .g m-3, respectively. Total concentration of PM10-associated PAHs reached 492.4 ng m-3 in winter and 26.0 ng m-3 in summer times. The multiple regression analysis was performed to predict total PM2.5- and PM10-associated PAHs and benzo(a)pyrene-equivalent (BaPE) concentrations with respect to meteorological parameters and particulate mass concentrations with the determination coefficients (R2) of 0.811, 0.805 and 0.778, respectively. The measured mean values of concentrations of total PM2.5- and PM10-associated PAHs were found to be 88.4 ng m-3 and 93.7 ng m-3 while their predicted mean values were found to be 92.5 ng m-3 and 98.2 ng m-3, respectively. In addition, observed and predicted mean concentration values of PM2.5-BaPE were found to be 14.1 ng m-3 and 14.6 ng m-3. The close annual mean concentrations of measured and predicted total particulate related PAHs imply that the models can be reliably used for future predictions of particulate related PAHs in urban atmospheres especially where fossil fuels are mainly used for heating. © 2009 Elsevier B.V.
