How do integrated quality and environmental management practices affect firm performance? Mediating roles of quality performance and environmental proactivity

Based on a sample of 208 Turkish firms, this paper investigates the integration of two management systems, quality management and environmental management, and explores the effect of this integration on firm performance. First, a conceptual framework was developed, relying on the premises of the resource‐based view. Second, mediating roles of quality performance and environmental proactivity were examined on the association between integrated quality and environmental management systems and firm performance. Among the underlying trends, both quality performance and environmental proactivity were found to fully mediate the relationship between integrated quality and environmental management and firm performance.     

Social media or shopping websites? The influence of eWOM on consumers’ online purchase intentions

This study empirically tests and compares the influence of friends’ recommendations on social media and anonymous reviews on shopping websites in the context of online purchase intention. For this purpose, we analyse the impacts of these two platforms based on the components of information adoption model (IAM) which are borrowed as information quality, information credibility, information usefulness and information adoption. We conduct a survey and find anonymous reviews as more influential on consumer’ online purchase intentions than friends’ recommendations on social media. However, as this result was contrary to that expected, we conduct another study through in-depth interviews in order to enlighten our results found in the first study. In Study 2, we find the reasons why consumers prefer anonymous reviews rather than friends’ recommendations. Information quantity, information readiness, detailed information and dedicated information are factors which make shopping websites superior than social media in terms of the impact of electronic word of mouth (eWOM). Academic and managerial implications are discussed.     

Telecommunications Policy Reform in Turkey

This paper, considering the economic effects of liberalisation in the telecommunications sector on the Turkish economy, makes use of the empirical studies on the linkages between regulatory regimes and telecommunications prices. Since Turkey is trying to liberalise the telecommunications sector by following the EU approach to liberalisation, the paper considers briefly the regulatory regimes in the telecommunications sectors of the EU and Turkey, determines the ad valorem equivalent of barriers to the telecommunications services sector in Turkey, and derives estimates of the welfare effects of adopting the EU rules and regulations in the Turkish telecommunications sector. It shows that there is tremendous scope for Turkey to benefit from adopting and implementing the legislative, regulatory and institutional framework of the EU telecommunications sector.     

Testing the proposed “GuidePerf” scale for tourism: performances of tour guides in relation to various tour guiding diplomas

The satisfaction perceived from the performance of tour guides (TGs) affects tour operators and other services in the tourism industry. As the tour guiding performance becomes more crucial in service quality and tourist satisfaction, education also becomes a critical tool to enhance the tour guiding performance. Using semi-structured, face-to-face interviews with seven TGs in Cappadocia/Turkey and employing content analysis of the data, the Tour Guide Performance Scale (GuidePerf) was developed in this particular study. Reliability and validity of GuidePerf were supported by exploratory factor analysis and confirmatory factor analysis. The scale was composed of 18 items and three dimensions, namely: “personality and efficiency,” “presentableness,” and “proficiency.” Proceeding to the next step with the approval, the GuidePerf was conducted on the tour participants (TPs) who were guided by three different TG types in terms of the education they had received. The results revealed that there is significance when “presentableness,” and “proficiency” dimensions are considered.     

Effects of spatial experiences & cognitive styles in the solution process of space-based design problems in the first year of architectural design education

There are many factors that influence designers in the architectural design process. Cognitive style, which varies according to the cognitive structure of persons, and spatial experience, which is created with spatial data acquired during life are two of these factors. Designers usually refer to their spatial experiences in order to find solutions to design problems. Information recalled from past spatial experiences lay the ground for creating the conceptual framework when solving a design problem. In addition, the person’s cognitive style, which develops through factors such as education, environment, genetics and family, can also be effective in solving design problems. In this line, an empirical study was conducted to research the effects of spatial experiences and cognitive styles on the solution process of spatial design problems in the first year of architectural design education. The study concluded that the cognitive styles of students were effective on their space creation method, order and duration.

CEO Overconfidence,REIT Investment Activity and Performance

This is the first article to study the effects of overconfidence on trading activity and performance in real estate. The article looks at Real Estate Investment Trusts (REITs), as their investments and divestments can be identified with precision. We look at the effect of CEO overconfidence on investment activity and separately investigate property acquisitions and dispositions. We find that REITs with overconfident CEOs tend to invest more; these REITs acquire more assets and are less likely to sell assets than their counterparts if they have enough discretionary cash. Valuable private information is not the main driver for CEOs to be net buyers of company shares: the shares of their companies perform relatively weakly. In addition, we find that overconfident managers have lower property investment performance measured by net operating income and gain on sale of real estate.     

Tactical crew planning in railways

Tactical crew capacity planning problem in railways involves finding the minimum number of crews in a region required to operate a predetermined set of train duties satisfying the strict day-off requirement for crew. For the single-region problem, we develop two solution approaches based on a space–time network representation: the sequential approach and the integrated approach. We also study the multi-regional capacity planning problem where we minimize total system-wide capacity by simultaneously considering multiple regions within a neighborhood search algorithm based on our solution methods for the single-region problem. We present the computational study on problem instances from Turkish State Railways.     

Information and consumer willingness to pay for biofortified yellow cassava: evidence from experimental auctions in Nigeria

In this article, we use the Becker‐DeGroot‐Marschak mechanism to estimate consumer demand for biofortified yellow cassava varieties in two states of Nigeria: Imo in the southeast and Oyo in the southwest. These two states exhibit distinct habitual product color preferences for staple food made with cassava. We estimate the effect of nutrition information campaigns and nature of planting material delivery institutions on consumer demand. Willingness to pay estimations account for the effect of product endowment, censoring in bids and nonpayment. In Oyo, consumers are willing to pay a premium for light yellow cassava variety even in the absence of nutrition information. The article finds that nutrition information results in a large and significant price premium for biofortified cassava in both states, and the nature of delivery institution has no significant effect.
