    This paper investigates whether or not the J-curve hypothesis holds in Turkish agricultural sector. The analysis is conducted using the model the most commonly employed in j-curve literature. Based on the data covering the period from 1986: I to 1998: III, our results indicate that, following devaluation, agricultural trade balance initially improves, then worsens, and then improves again. This pattern shows that J-curve effect does not exist in Turkish agricultural sector. Another important fi nding is that devaluation worsens the trade balance of the sector in the long run, a result contradicting with the earlier fi ndings for the Turkish economy as a whole

    The purpose of this study is to reveal the relationships between middle school students’ emotional expression levels and their self-concept, gender, and school types. It was conducted on the seventh-grade students of five middle schools in Sivas province in the 2016-2017 academic year.  Relational survey model was used. The Emotional Expression Questionnaire developed by King and Emmons (1990) and adapted into Turkish by Kuzucu (2011) and the Social Comparison Scale adapted into Turkish by Şahin, Şahin, and Durak (1993) were used as measurement tools. No significant difference was found between the emotional expression levels of the females and the males. However, the females were found to have significantly higher social comparison scores than the males. A significant difference was found between the scores obtained from the Emotional Expression Questionnaire by school type. A low-level significant, positive relationship was found between the scores obtained from the Emotional Expression Questionnaire and those obtained from the Social Comparison Scale.   Article visualizations

    UČINAK TEČAJA I CARINSKE UNIJE NA TRGOVINSKU BILANCU SIROVINA TURSKE S EU (15)

    This paper investigates the short-run and long-run impact of exchange rate and customs union on the trade balance at commodity-group level of Turkey with EU (15). Bounds testing approach is employed where a new strategy in the model selection phase is adopted ensuring that optimal model is selected from those models satisfying both diagnostics and cointegration. Results indicate that in the short-run exchange rate matters in determination of trade balance of 13 commodity groups out of 21 and customs union in 8 cases. Pattern of response of trade balance to exchange rate does not suggest a J-curve effect in any of cases. As for the long-run effect, neither exchange rate nor customs union has a statistically significant effect on trade balance of any of commodity groups, suggesting that those significant short-run effects don’t last into long-run.Ovaj rad proučava kratkoročni i dugoročni učinak tečaja i carinske unije na trgovinsku bilancu sirovina Turske s EU (15). Koristi se pristup graničnog testa gdje se u fazi odabira modela koristi nova strategija koja osigurava odabir optimalnog modela između onih koji udovoljavaju kako dijagnostici tako i kointegraciji. Rezultati ukazuju da, kratkoročno gledano, tečaj ima utjecaja na određivanje trgovinske bilance 13 grupa sirovina od 21, dok carinska unija utječe u 8 slučajeva. Uzorak odgovora trgovinske bilance na tečaj ne ukazuje na efekt J-krivulje ni u jednom slučaju. Što se tiče dugoročnog učinka, niti tečaj niti carinska unija nemaju statistički značajan učinak na trgovinsku bilancu bilo koje grupe sirovina, ukazujući na to da viđeni kratkoročni učinci ne prelaze u dugoročne

    Get PDF
    Nowadays, data is ubiquitous and gives businesses capabilities they did not have access to before. Data analytics helps organizations transform raw data into valuable insights and is, therefore, a critical asset to any organization as a baseline for any important tactical, operational, and strategic decisions. However, although data analytics provides many benefits, new security challenges have emerged that hamper the effectiveness of organizational analytics efforts. New approaches to security are required to address these challenges. This research in progress paper provides an overview of security-related challenges surrounding data analytical solutions. In addition, the paper discusses shortcomings of current governance and security frameworks in addressing data analytics-specific security challenges and presents avenues for future research

    FUNKCIJE UVOZNE I IZVOZNE POTRAŽNJE TURSKE POLJOPRIVREDE: PROCJENE PRISTUPOM GRANIČNOG TESTA

    This paper estimates the import and export demand functions for Turkish Agriculture based on the annual data for 1970-2003. The bounds testing approach to the cointegration and the error correction modeling is employed. We, however, adopt a new strategy in the model selection phase and select the optimal model from those models that satisfy both diagnostics and cointegration, thus, unlike the previous literature, ensuring that a statistically reliable and cointegrated model is picked up. Estimation results indicate that for the import demand, relative price is a significant determinant in both short-run and long-run, nominal effective exchange rate matters only in the long-run, but domestic income is not at all a significant determinant for Turkish agricultural import demand. As for the export demand, while all determinants affect the export demand significantly in the short-run, given the relatively small share of Turkish agricultural exports within the world agricultural exports, none individually matters in the long-run.Ovaj rad procjenjuje funkcije uvozne i izvozne potražnje u turskoj poljoprivredi na osnovu godišnjih podataka za period od 1970-2003. Za kointegraciju se koristio pristup graničnog testa i model ispravljanja pogreške. Ipak, primijenili smo novu strategiju u fazi odabira modela te odabrali optimalni model među onima koji su na najbolji način zadovoljili kako dijagnostiku tako i kointegraciju te tako, za razliku od prethodne literature, osigurali odabir statistički pouzdanog i kointegriranog modela. Rezultati procjene ukazuju na to da je relativna cijena značajna determinanta za uvoznu potražnju, kako kratkoročno tako i dugoročno, nominalni efektivni tečaj ima utjecaja samo dugoročno dok domaći dohodak uopće nije značajna determinanta za tursku poljoprivrednu uvoznu potražnju. Što se tiče izvozne potražnje, dok kratkoročno sve determinante značajno utječu na izvoznu potražnju, s obzirom na relativno mali udjel turskog poljoprivrednog izvoza u svjetskom poljoprivrednom izvozu, niti jedna zasebno nema dugoročni utjecaj

    Get PDF
    Background: Substance abuse is a serious problem all over the world. There are many studies report the illegal substance use profile but few studies present their toxicology laboratory analysis. This study reports a quantitative profile of (Urine Drug Screening)) for illegal substances in Sakarya-Turkey.Methods: This study presents the urine analysis of all illegal substances which were made in the laboratory of Sakarya Training Research Hospital between March 2012 and February 2015. The results obtained from socio-demographic data and urine tests of patients were analyzed by examining their hospital record files. Urine drug screening was conducted with immunoassay quantitative analysis.Results: People subjected to substance analysis (n=2948) ages vary between 12 and 76, their mean age was 28.30±9.46. 96.74% (n=2852) of them were males. Substance positivity was determined in 34.73% of all patients (n=1024/2948) and their ages varied between 14 and 70 and their mean age was 29.39±9.65. Distribution of the urine positivity of the substances contained: marijuana 79, 5% (n=814), amphetamine 30.17% (n=309), ecstasy 23.74% (n=199), benzodiazepine 9,1% (n=94), synthetic cannabinoid 4.9% (n=12/243); opioid 5.2% (n=54), cocaine 1.67% (n=14) and multiple substance 29.9% (n=308).Conclusions: According to this study, marijuana is the most frequently used substance and multiple substance use is common. Synthetic cannabinoid seems to take place rapidly among the users. Updating the kits is important to reach the correct information in drug screening tests

    Firm size and job creation: evidence from Turkey

    Get PDF
    This study examines the relationship between firm size and job creation by using an extensive data set covering all non-farm Turkish businesses with 20 or more employees from 2003 to 2010. We find that small firms (firms with employees between 20 and 100 employees) have higher mean job flow rates (job creation, job destruction and net job creation rates) than large firms. Firm size and job flow rates are inversely related, and this relationship is especially prominent for firms with 50 employees or more. Although the overall pattern observed is also observed in both sectors, job creation rates in services are higher than the ones in manufacturing. The magnitudes of job destruction rates are comparable across sectors. Higher job creation rate in services but comparable job destruction rate results in higher net job creation rate in services. As for shares, only for smaller firms (20-49 and 50-99 size categories), job creation shares are greater than their shares in employment. But these firms have disproportionate job destruction shares as well. We also find that only the 20-49 category firms contribute to net job creation more than their share in employment. The smaller firms have high disproportionate shares in job creation and destruction in manufacturing and services as well

    Near-field radiation from nano-particles and nano-antennas illuminated with a focused beam of light

    Get PDF
    The interaction of photons with metallic nanoparticles and nanoantennas yields large enhancement and tight localization of electromagnetic fields in the vicinity of nanoparticles. In the first part of this study, the interaction of a spherical nanoparticle with focused beams of various angular spectra is investigated. This study demonstrates that the focused light can be utilized to manipulate the near-field radiation around nanoparticles. In the second part of this study, the interaction between linearly and radially polarized focused light with prolate spheroidal nanoparticles and nano-antennas is investigated. Strong and tightly localized longitudinal components of a radially polarized focused beam can excite strong plasmon modes on elongated nanoparticles such as prolate spheroids. The effect of a focused beam on parameters such as the numerical aperture of a beam and the wavelength of incident light, as well as particle geometry and composition are also studied

    Myocardial infarction secondary to unintentional ingestion of hydrogen peroxide

    Get PDF
    Ingestion of acid-containing household products, either accidentally or as a suicide attempt, is a common form of intoxication. A clear and odorless liquid, hydrogen peroxide is an oxidizing agent found in most households and many industrial environments. Cardiovascular manifestations of hydrogen peroxide ingestion are extremely rare. Here we report a 60 year-old woman with acute inferolateral myocardial infarction (MI) after hydrogen peroxide ingestion, who had no history of coronary artery disease. Physicians dealing with hydrogen peroxide ingestion in the emergency department should be aware of the probability of MI and obtain an electrocardiogram, even if the patient has no cardiac complaint.

    WOS: 000290915100012PubMed: 22291766Introduction: We investigated the association between bone mineral density (BMD) detected by dual-energy X-ray absorptiometric (DXA) method and blood pressure (BP) in a large sample of postmenopausal women. Material and methods: The current study was based on a retrospective analysis of 586 postmenopausal women with a mean age of 60.8 +/- 8.8 years, who were screened for osteopenia or osteoporosis by DXA. Patients with hypertension (HT, n = 306) were compared with normotensive (NT, n = 290) individuals. Bone mineral density results for the femur neck and spine were classified into 3 groups according to World Health Organization criteria: normal (T score > -1.0 SD), osteopenia (T score -1.0 to -2.5 SD) and osteoporosis (T score <-2.5 SD). Patients with osteopenia or osteoporosis (T score < -1.0 SD) were grouped as having low bone mass (LBM). Results: There were no significant differences in femur T score, femur BMD, femur Z score, spinal T score, spinal BMD and spinal Z score between hypertensive and normotensive groups. The group of patients with low bone mass calculated from femur T scores had higher age, systolic BP, duration of hypertension and duration of menopause, but lower BMI. Similarly, patients with low spine BMD had higher age and duration of menopause, but lower BMI. Linear regression analysis showed a significant correlation between systolic BP and femur BMD and T score values. Furthermore, logistic regression analysis revealed that hypertension is an independent predictor of spinal osteopenia and osteoporosis. Conclusions: The presence of hypertension is an independent predictor of spinal low bone density in Turkish women after menopause
