    Assessment of determinants for households' pro-environmental behaviours and direct emissions
    (Elsevier Sci Ltd, 2023) Buelbuel, Hasan; Topal, Ayse; Ozoglu, Buket; Buyukkeklik, Arzum
    This study aims to analyse the effect of environmental awareness, the mediating effect of environmental willingness and the moderating effects of demographics to better understand how pro-environmental behaviours and carbon emissions are affected and make recommendations on how to improve them. The structural equation modeling and multi-group analysis were employed to analyse the data collected from households in Turkiye. This study's novelty lies in the measuring model designed to consider moderating effects of demographics and mediating effects of environmental willingness on pro-environmental behaviours and carbon emissions in Turkish households. The results show that household demographics have moderating effect. It has also been found that environmental willingness plays a mediating role between environmental sensitivity and pro environmental behaviours. In addition, it is found that nothing affects direct carbon emissions. The main reason may be the use of standard equipment in the residences. Various implications for the public and private sectors have been given in conclusion to increase pro-environmental behaviours and to decrease emissions through considering environmental sensitivity, environmental willingness, and demographics.

    Estimating The Amount of Municipal Waste in Turkey with the Linear Fuzzy Regression Model
    (Sosyoekonomi Soc, 2022) Ozer, Fatmanur; Buyukkeklik, Arzum
    Waste management in both Turkey and the World has been of great importance in the 21st century. As a developing country, Turkey wants to reach an adequate waste management system like developed countries and tries to harmonize its laws on waste. This study aims to reveal the relationship between municipal waste generation and socioeconomic indicators and estimate the amount of municipal waste generated in Turkey between 2005 and 2019 by using Tanaka's linear fuzzy regression model. This study has revealed indicators affecting the municipal waste generation and generation projection between specific years. Population growth rate, GDP per capita, and literacy rate indicators that were thought to be more effective and easier to reach the data were used as independent variables. The total amount of municipal waste in Turkey was the dependent variable in the modelling. It is expected that the established projection model will benefit the development of forecasts about waste generation in the future and thus will contribute to the investments and planning for waste recovery and safe disposal.

    The Effects of COVID-19 Outbreak on Supply Chains and Logistics Activities
    (Tuba-Turkish Acad Sciences, 2020) Senir, Gul; Buyukkeklik, Arzum
    A virus called COVID-19, which emerged in Wuhan, China in December 2019, crossed the country's borders and was on the global agenda in a short period of time. In order to reduce the speed of the spread of the pandemic, the quarantine practices and curfews of countries caused significant breaks both in the countries' economies and in the global economy. The COVID-19 outbreak showed the vital importance of supply chains and logistics as well as the commercial deficiencies of the globalizing world and increased the need for reliable supply chains. During the pandemic process, it has been understood that all supply chains and logistics operations should function flawlessly from supply to production, warehouse operations to transportation, e-commerce to cargo and courier services in order to reach food, health, cleaning and all other basic consumer products easily and quickly. The aim of this study is to evaluate what happened in the supply chains and logistics operations with the COVID-19 outbreak and to develop predictions about possible changes for these areas after the pandemic. The effects of pandemics on supply chain, logistic sector, and especially logistic activities in Turkey are examined. The measures taken for the logistics sector, the expectations of the sector, and the possible changes in supply chains and logistics activities for post-pandemic period are discussed. It is thought that the localization for the supply chains, easy access to suppliers and customers, flexibility, dynamism and digitization will be areas for improvement after the pandemic. The contactless transport models; multi-location, dynamic, low-cost storage approaches; improving communication in logistics services; digitalization; cargo services adapting quickly to demand fluctuations will come to the fore as the topics to be developed in the logistic sector. It is thought that supply chain in health, humanitarian logistics, reverse logistics, closed-loop supply chain issues and the sustainability of supply chains will be areas to be studied and focused by both practitioners and academicians in the post-pandemic period.

    The relationship between environmental awareness, environmental behaviors, and carbon footprint in Turkish households
    (Springer Heidelberg, 2020) Bulbul, Hasan; Buyukkeklik, Arzum; Topal, Ayse; Ozoglu, Buket
    Having knowledge about household environmental behaviors is important for planning and conducting efforts to reduce carbon footprint. In this study, the relationship between environmental awareness, purchasing, household practices, and carbon footprint was investigated, and the impact of demographics on these variables was determined. The analysis shows that sensitivity dimension of environmental awareness is related to few environmental behavior variables (purchasing and efficiency) whereas willingness dimension was related to all variables (except gas). While improvements in demographic factors (income, education, and female employment status) positively affect environmental sensitivity, they increase carbon footprint from automobile. Only increase in income has an effect on willingness. It is determined that income positively affects environmental purchasing. Furthermore, it is revealed that environmental household practices did not differ in terms of demographic characteristics, except the effect of education on pollution.
