    INFLUENCE OF FOREIGN DIRECT INVESTMENT ON CARBON DIOXIDE EMISSIONS IN NEWLY INDUSTRIALIZED COUNTRIES: A PANEL ARDL-PMG APPROACH
    Dam, MM; Gökbunar, AR; Yildiz, B; Bulut, S
    In this study, the effect of foreign direct investment on carbon dioxide emissions was analyzed using annual data for the 1990-2016 period for the newly industrialized countries. The study was analyzed using Panel Pooled Mean Group-Autoregressive distributive lag cointegration test and Dumitrescu and Hurlin panel causality test. As a result of the long-term analysis, the foreign direct investment, energy consumption and trade openness have a positive and significant impact on carbon dioxide emissions whereas economic growth has negative and significant impact on carbon dioxide emissions. It has been analyzed that a 1% increase in foreign direct investment increases carbon dioxide emission by 0.03%. According to Dumitrescu and Hurlin panel causality tests analysis results, a bidirectional causality relationship between energy consumption and carbon dioxide emissions; a unidirectional causality relationship from economic growth and trade openness to carbon dioxide emissions and from carbon dioxide emissions to foreign direct investment has been determined.

    Effect of ground poppy seed as a fat replacer on meat burgers
    Gök, V; Akkaya, L; Obuz, E; Bulut, S
    Poppy seed paste was used in koefte production as an animal fat replacer and efficacy of using poppy seed was investigated. The use of ground poppy seed in formulation of meat burgers had no effect on the moisture content of uncooked meat burgers; however, it did have a significant effect (p<0.05) on the fat content of meat burgers. Ground poppy seed addition significantly affected (p<0.05) cooking yield, moisture retention, and fat retention of meat burgers. Ground poppy seed addition significantly decreased (p<0.05) saturated fatty acid contents as the amount of ground poppy seed increased in meat burgers. A strong significant decrease (p< 0.05) on the cholesterol content of meat burgers with ground poppy seed addition was observed. Samples having 20% ground poppy seed had significantly better texture and juiciness score (p<0.05) than any other sample which could be explained by increased moisture retention. Replacing animal fat with ground poppy seed paste is effective and may pave the way for an innovative meat product. (C) 2011 Elsevier Ltd. All rights reserved.

    Validity and reliability of the Turkish version of the adult ADHD Self-Report Screening Scale for DSM-5
    Genç, HA; Yorguner, N; Bulut, S; Bulut, GC; Aydemir, Ö; Yazgan, Y
    Background: Approximately half of the children with attention-deficit hyperactivity disorder continue to meet diagnostic criteria in adulthood. The prevalence of adult attention-deficit hyperactivity disorder is reported between 2.5% and 4.4% and is associated with significant impairment in quality of life and increased psychiatric comorbidity. Attention-deficit hyperactivity disorder in adults remains mostly undiagnosed and/or untreated despite the availability of effective treatments. The majority of people who do not receive necessary treatment are in the nonclinical or nonpsychiatric clinical population. Screening is an important step for diagnosing adults with attention-deficit hyperactivity disorder. Yet, there are no valid and reliable screening questionnaires calibrated for the Diagnostic and Statistical Manual for Mental Disorders-5 in Turkish. Aims: We aimed to test the reliability and the validity of the Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5 screening questionnaire designed according to DSM-5 in the Turkish population. Study Design: Methodological and cross-sectional study. Methods: The translation was carried out according to the World Health Organization Composite International Diagnostic Interview translation guide using a linguistic adaptation approach. We used a convenience sampling method to recruit an individual with adult attention-deficit hyperactivity disorder (n = 68) and a control group (n = 68). The participants completed a sociodemographic form, 6-items Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5, and the previous version 18-items Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-v1.1 for the concurrent validity analysis. For the diagnostic validity, clinical diagnosis made by psychiatrists according to the Diagnostic and Statistical Manual for Mental Disorders-5 criteria was used. Internal consistency and item-total correlation coefficients, exploratory factor analyses, correlation with Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-v1.1, and receiver operating characteristic curve analysis were conducted. Results: The internal consistency measured by Cronbach alpha was 0.869. Item-total correlation coefficients were calculated to be between 0.602 and 0.717, and the correlations were statistically significant (P < 0.0001). The Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5 showed to have a unidimensional factor structure explaining 60.54% of the variance. The correlation between Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5 and Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-v1.1 total score was calculated as 0.992 (P < 0.0001), and that between Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5 and Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-v1.1 attention-deficit subdimension was 0.868 (P < 0.0001). In the receiver operating characteristic analysis of Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5, the area under the curve was found to be 0.916. The cut-off score was calculated as 9 of 10 with a sensitivity of 85.2% and specificity of 89.7%. Conclusion: Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale-5 is a valid and reliable self-report measure to assess and screen attention-deficit hyperactivity disorder in the Turkish population. It may be useful for both clinical and population studies.
