Ozdemir, Yasal; Kaya, Sema Kayapinar; Turhan, Erkan
This study aims to develop a measuring tool which can address two independent research areas in the literature: Sustainability in higher education and service quality in higher education. Both subjects are studied independently in the literature, showing a need for an integrated approach that bridges these areas. For achieving this purpose, a new scale was developed based on a questionnaire applied to two universities in Turkey. The scale aimed to measure the perceptions of the students regarding the quality of sustainable campus services. The questionnaire consisted of 22 questions on several aspects of campus services which are related to sustainability. A total of 234 samples were used for Exploratory Factor Analysis for determining the underlying structures in the data set. The scale was validated with satisfactory Kaiser-Meyer Olkin and Bartlett's test results. Five dimensions were extracted, which represent sustainable service quality. After validation, the scale was applied to two universities located in geographically and socio-economically different regions of Turkey. The term chosen for the proposed combined scale is Sustainable Service Quality (SusServQual). With additional data, t-tests were applied to 308 students aiming to compare the two universities based on perceived quality scores. The results show that the university located in the socio-economically more developed region performed better regarding the overall satisfaction score and four of the five dimensions. The scores were also weighted utilizing a modified method of Analytical Hierarchy Process. Instead of crisp numbers which forces the decision maker to think in mathematical terms while comparing criteria, linguistic terms, each of which corresponds to a fuzzy number were used. Thus, a more accurate evaluation was obtained where the decision maker's subjectivity and ambiguity of the situation are important.

İncele - MakaleYalnız künye2020Scopus SJRQ2“Home-buying behaviour model of Generation Y in Turkey”
Kayapinar Kaya, Sema; Ozdemir, Yasal; Dal, Murat
Purpose: The young population in Turkey is gradually increasing. Generation Y, which comprises the people born between 1980 and 1999 (Broadbridge et al., 2007) and free-spirited and tech-savvy, forms a large part of the population of the world, especially Turkey, and is of great importance to the housing sector for their home-buying preferences. In this study, housing preferences of students in Turkey’s two socio-economically different universities were comparatively analysed through quantitative methods. Design/methodology/approach: A survey was simultaneously distributed among students of two universities. The survey consists of six main factors: “reliability”, “economic opportunities”, “transportation opportunities”, “quality of life and social opportunities”, “quality standards”, and “technological opportunities”, with 25 statements. The questionnaire was developed through a comprehensive literature review and the opinions of university stakeholders. Findings: Results showed that the structure of the family and socio-economic differences affect home-buying preferences. The Mann–Whitney U test indicated that there was a meaningful difference of opinion between students of two universities. Munzur University students paid attention to economic opportunities when buying a home. Additionally, there was a meaningful relationship among the age groups in factors of “having a parking place” (p = 0.026) and “having a playground” (p = 0.026). As the age increases, students desire a playground around their future home. Research limitations/implications: The most important limitation of this study is the non-parametric data. Non-parametric data structure and the tests performed accordingly are less preferred than parametric data structure. For that reason, to what extent the results accurately represent Generation Y needs to be assessed through future study. Also, a certain number of sampling could be reached as purposive sampling was used. Originality/value: This study contributes to the literature in terms of comparatively analysing buying preferences of Generation Y through statistical methods and showing the relationship between these preferences and socio-economic features statistically. Due to the insufficient quantitative research on the literature, this quantitative study was carried future home-buying preferences of Generation Y university students, who will also be actively involved in the housing market. The purpose of this study investigates marketing factors that affect housing preferences of students in Turkey.

Ozdemir, Yasal; Gul, Muhammet
Regional development seeks to better understand the issues and problems facing the regions because of the contemporary economic and social changes, including the formulation of territorial policies accordingly. In Turkey, in order to coordinate regional development, 26 regional development agencies were founded relating to the nomenclature of territorial units for statistics-2 (NUTS-2) regions. Since these regions have different development levels, it is useful for stakeholders to determine performance measures related to the regional development and propose a ranking model among these regions to provide a balance in delivering financial support mechanisms. Therefore, in this study, an iterative multi-criteria decision-making (MCDM) model is proposed. Firstly, Pythagorean Fuzzy Analytic Hierarchy Process (PFAHP) is used to assign weights to indicators of well-being index for provinces (WiP) in Turkey. Then, a TODIM (an acronym in Portuguese of interactive and multiple attribute decision making) based ranking model for 26 regions was applied. Also, this model takes capabilities and well-being approach into account differently from traditional utilitarian development models which take only some macro-economic and financial parameters. In order to do this, the model uses data from WiP. On conclusion, a comparative ranking projection with two other MCDM methods and WiP is provided and an effective and broader point of view was gained by the regional development performance measuring model.

Ozdemir, Yasal; Gul, Muhammet; Celik, Erkan
University laboratories involve various occupational hazards during the research and course activities, which might affect health and safety of both researchers and students, including chemical, physical, electrical, mechanical, as well as ergonomic and psychosocial risk factors. There are many aspects open to improvements in Occupational Health and Safety management of laboratories, and it is required to deal with risks, reduce them in an acceptable level, and implement control measures. In this study, a risk assessment approach is proposed for the university laboratory operations. The proposed approach incorporates 5S methodology, failure modes and effects analysis (FMEA), interval type-two fuzzy sets (IT2FSs), analytic hierarchy process (AHP), and the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR). AHP is injected into IT2FSs in the phase of evaluation and weighting of severity (S), occurrence (O), and detectability (D) parameters of FMEA. By applying IT2FVIKOR, it is aimed at prioritizing the emerged hazards in the chemical laboratory of the observed university. The proposed approach reveals the important hazards and suggests control measures for managing them. The study methodologically contributes to risk assessment in the knowledge, while a case study in a chemical laboratory of a newly established university offers an insight into education industry in safety improvement.
