Behavioral aspects of regulation: A discussion on switching and demand response in Turkish electricity market

Electricity sector has been transformed from state-owned monopolistic utilities to competitive markets with an aim to promote incentives for improving efficiency, reducing costs and increasing service quality to customers. One of the cardinal assumptions of the liberalized and competitive electricity markets is the rational actor, and decision-makers are assumed to make the best decisions that maximize their utility. However, a vast literature on behavioral economics has shown the weakness of economic theory in explaining and predicting individuals’ decision-making behavior. This issue is quite important for competition in electricity markets in which consumers’ preferences have a significant role. Despite its importance, this issue has almost been neglected in Turkey, which has taken major steps in electricity sector restructuring. Therefore, this paper aims to examine switching and demand response behavior in Turkish electricity market by using multiple correspondence and panel data analysis, and findings are discussed in light of the neoclassical and behavioral economics literature. Analyses’ results show that consumers’ switching and demand response behavior is consistent with the neoclassical literature to some extent; however, behavioral factors are also affecting consumers’ decisions. Furthermore, there are systemic problems that hinder effective functioning of the electricity market and restrict competition.     

Vocational college students' acceptance of web-based summative listening comprehension test in an EFL course

There is a substantial increase in the utilization of web-based assessment procedures to assist teaching and learning processes in higher education institutions. Despite their benefits, institutions use them to a limited extent due to a number of factors influencing both instructors' and students' behaviors. This study examines students' acceptance of a web-based summative listening test administered in the 2014–2015 academic year within an ‘English as a Foreign Language' course at a two-year post-secondary military school in Turkey. The participants consisted of 602 military students. As a model, Computer Based Assessment Acceptance Model based on Technology Acceptance Model was adopted in order to analyze the participants' perceptions on a web-based summative listening comprehension test. The data were collected via an online questionnaire. A structural equation modeling analysis was utilized to analyze the relationships among factors. The general results showed that perceived ease of use and perceived playfulness had a direct influence on the participants' behavioral intentions to use web-based tests. In other words, web-based tests are expected to be used if they are easy to use and playful enough.

Genetic and environmental influences on problematic Internet use: A twin study

Despite many studies on the prevalence and correlates of problematic Internet use (PIU), we know little about its etiological components. Our main aim is to find out to what extent PIU is influenced by genetic and environmental factors using the classic twin design. A total of 237 Turkish twin-pairs aged 10–25 participated in the study. PIU was measured using the ‘Problematic Internet Use Scale’ (PIUS) developed by Ceyhan, Ceyhan and Gürcan. For male twin-pairs, the monozygotic (MZ) twin correlations were larger than the dizygotic (DZ) twin correlations, indicating that genetic factors influenced scores on the PIUS. However, for female twin-pairs, the MZ correlations were smaller than the DZ correlations for the PIUS, showing that genetic factors did not play a role in female twin-pairs. The influence of both genetic and environmental factors was explored with model-fitting analysis. Results showed that both for the “social comfort/benefit” and “negative consequences associated with the Internet use” sub-dimensions, the best-fitting models were the ADE models whereas both for the “excessive use” sub-dimension and “PIUS-Total”, the best-fittings models were the ACE models. The key result of this study is that the genetic and non-shared environmental effects are equally influential on the overall PIU in male twin-pairs.

Discrediting in a Message Board Forum: The Effects of Social Support and Attacks on Expertise and Trustworthiness

Given the prevalence of online media today, credibility continues to be a popular subject of empirical research. However, studies examining the effects of discrediting strategies are rare. This issue is significant given the popularity of online media and the ease of such sources to spread misinformation. Therefore, the present study examines the effects of attacking the expertise and trustworthiness of a proponent of a major social issue. Results showed that support as well specific combinations of discrediting attack strategies significantly reduced message board readers' perceptions of the proponent's credibility. In addition, attacks on either the proponent's expertise or trustworthiness resulted in a reduced likelihood of readers taking action with respect to the issue.     

从师承关系的角度研究日本当代建筑设计的主流特征

日本有着完整的现代建筑发展史,日本建筑师凭借着其一代代的传承与创新在世界范围内取得了广泛的影响力。同时,在每一代建筑师的努力下,日本每个时期的建筑都呈现出鲜明的特点。对比现代主义时期,日本当代建筑已经呈现出完全不同的风格。本文将结合日本建筑师的代际关系与时代背景,纵向解读日本现代建筑的发展演变并剖析日本当代建筑设计倾向转变的原因,同时,以师承关系为主要线索,通过对日本当代几位重要建筑师的创作手法及其创作观念的分析,总结出日本当代建筑设计的主流特征。
