    Are shocks to disaggregated energy consumption transitory or permanent in Turkey? New evidence from fourier panel KPSS test
    (Pergamon-Elsevier Science Ltd, 2020) Erdogan, Sinan; Akalin, Guray; Oypan, Oguz
    The investigation of the stationarity property of energy consumption has recently been a challenge for researchers in energy economics and important for consistent policy proposals. This study uses a set of conventional unit root tests and a recently developed Fourier panel KPSS test to investigate the persistence of shocks in disaggregated energy consumption data in Turkey from 1970 to 2016. The empirical results are as follows. First, the results of the unit root tests with no structural breaks reveal that energy consumption is overwhelmingly nonstationary in regard to sectoral energy consumption, except for the government's consumption; additionally, panel statistics also indicate that energy consumption is nonstationary. Second, the results of the stationarity test that allows multiple structural breaks reveal that sectoral energy use is stationary, but the panel results are controversial. Third, the Fourier panel KPSS test shows that energy use is nonstationary at both the sectoral and the panel level. Overall, the empirical findings indicate that disaggregated energy use is nonstationary, and that the effects of possible shocks on energy consumption in Turkey are permanent. Therefore, stabilization policies on energy consumption are required to avoid a possible spillover effect of energy shocks on other macroeconomic variables. (C) 2020 Elsevier Ltd.

    Identification of the drivers of and barriers to COVID-19 vaccine intake behavior using a mixed-method design: implications from a developing country
    (Elsevier Espana, 2023) Kordestani, Arash; Oghazi, Pejvak; Izmir, Onur; Oypan, Oguz; Ozer, Serhat
    Various COVID-19 vaccines are available across the world. However, short phases of clinical trials for emer-gency use and myriad rumors about and misinformation on vaccines spread through different media sources, induce confusion and trigger vaccine hesitancy behavior. Although clinical trials demonstrated promising results in the ability of vaccines to protect, social endeavor is required for vaccines to succeed. Mitigation of the pandemic is only possible through widespread acceptance of the vaccine. Thus, identifying the factors that impact vaccine intake is crucial. This study determined factors that affect intentions toward vaccination using a mixed-method approach, in which qualitative and quantitative analyses were conducted together. Analysis of variance (ANOVA) is used in the quantitative study, and content analysis is employed in the quali-tative study. The final sample of this mixed-method study consists of 568 participants for the quantitative study and 237 for the qualitative study. They were selected using an online questionnaire. Findings suggest that social, psychological, attitudinal, perceptual, and informational factors play a crucial role in shaping peo-ple's intentions toward vaccines, ultimately influencing their decision to accept or reject vaccination. Results of both the qualitative and quantitative studies, in parallel with each other, indicated similar barriers against and drivers toward vaccine intake behavior, providing strong insights into the reasons behind vaccine accep-tance and hesitancy. Based on the insights gained in this study, a set of recommendations were compiled for policymakers.& COPY; 2023 The Author(s).

    This study aims to evaluate the features, socio-economic and cultural aspects of the advertisements of Hatay Newspaper which was published in 1938, by content analysis. Ad texts were analyzed according to the structured and systematized coding scheme. In the research findings, simplicity of the advertisements, plain narration, being as an announcement and direct expression appear as the main features of that period. Information strategy was mostly used as a message strategy. Also, it's observed that typography of advertisement is strong and that the print and punctuation marks are based on artistic and design. In parallel to the saving campaign in Turkey, bank advertisements; in parallel with the literacy campaign, printing-house ads; and in parallel to the clothing revolution, tailor's workshops ads are seen. Reflections of tendencies such as going to cinema and holidaying are seen in cinema and hotel advertisements. Although Turkish is accepted as the official language, it can be said that Arabic words are frequently used in the language and thus, the advertisements reflect the transition period in the language. The original value of the study is examined for the first time the past advertisement texts of a local newspaper in Hatay and, contributed to Turkey's advertising history literature.
