Item Open Access Analysing school-museum relations to improve partnerships for learning: A case study(Türk Eğitim Derneği, 2020) Ateş, Aysun; Lane, Jennie F.Field trips to museums can improve student learning by providing them with opportunities to see first-hand concepts they learned in the classroom. Unfortunately, perceived and real barriers may discourage partnerships between schools and museums for education. The current paper describes how case study methodology was used to examine relations between a school and museums. Through this case study, a phenomenographic research approach was used to gain insights into museum educators and teachers’ perceptions and practices related to museum education. The research was conducted in Ankara, Turkey, involving teachers from a private school and seven staff from local museums. This study utilized quantitative data to support qualitative data. Through interviews, questionnaires, and an analytical framework, the results revealed the importance of identifying roles associated with museum education and strengthening pathways for communication. Based on the results of the study, the authors provide suggestions to improve partnerships between a school and local museums. One strategy is to identify a school staff member who serves as a liaison between the school and the museums, ensuring consistent communication and sharing of ideas. Future research ideas for consideration are identifiedItem Open Access A case study on the perceptions of professional development unit members at an EFL program(2019) Peker, Hilal; Özkaynak, O.; Arslan, Z.; Tunç, H.Prior research focusing on teacher training indicated that professional development is considered as a continuous process, and trainings are essential for teacher development. In this qualitative case study, researchers examined the perceptions of professional development unit (PDU) members regarding the training sessions they offered at a foundation university in Turkey. After ethical committee permissions were obtained, the data were collected through semi-structured interview questions besides note taking during the interviews. There were five PDU members as participants. Content analysis was utilized after all the notes and transcriptions were brought together. To carry out the content analysis, the researchers employed a modified van Kaam method as defined by Moustakas (1994). Thematically analyzed data indicated three main findings: continuous professional development, good rapport, and motivation. These themes are discussed as reflected by the participants and implications are provided for future professional development series.Item Open Access Designing an intervention strategy for public-interest goods: The California electric vehicle market case(Elsevier, 2017) Demirci, E. Z.; Erkip, N. K.We study the intervention problem for public-interest goods. Public-interest goods are known as goods with positive externalities, allowing the consumer as well as others who do not pay for them benefit from the consumption. Health related goods, such as vaccines, or products with less carbon emissions are well known examples. We consider a supply chain for such a product. Generally, wider adoption or usage of such goods is ensured by the intervention of a central authority in their supply chain. We explore the problem for a setting composed of a retailer and a central authority. The main goal of the central authority is to design and fund an intervention scheme so that decisions of the channel are in line with the good of society, specified as a social welfare function. We propose two intervention tools applied simultaneously: (1) investing in demand-increasing strategies, which affects the level of the stochastic demand in the market; and (2) rebates that affect revenue per unit received by the retailer. We introduce a model that determines a utility maximizing intervention scheme and further investigate the model. We also present two decentralized approaches as benchmarks. Finally, we conduct a case study for California׳s electric vehicle market and validate our findings by a detailed analysis of the results, including comparisons with the current practice.Item Open Access Designing intervention strategy for public-interest goods(2016-09) Demirci, Ece ZelihaPublic-interest goods, which are also referred as goods with positive externalities, create benefits to individual consumers as well as non-paying third parties. Some significant examples include health related products such as vaccines and products with less carbon emissions. When positive externalities exist, the good may be under-produced or under-supplied due to incorrect pricing policies or failing to value external benefits and that is why a need for intervention arises. A central authority such as government or social planner intervenes into the system of these goods so that their adoption levels are increased towards socially desirable levels. The central authority seeks to design and finance an intervention strategy that will impact the decisions of the channel in line with the good of the society, specified as social welfare. A key issue in designing an intervention mechanism is choosing the intervention tools to incorporate. The intervention tools can target the supply or demand of the good. One option for the intervention tool is investment in demand-increasing strategies, which affects the level of stochastic demand in the market. Second option is investment in strategies that will improve supply of the good. Alternatives for this option include registering rebates or subsidies and investment in yield-improving strategies when production process faces imperfect yield. As several real life cases indicate, central authority operates under a limited budget in this environment. Thus, we introduce and analyze social welfare maximization models with the emphasis on optimal budget allocation. We model the lower level problem, which represents the channel as a newsvendor problem. We then utilize bilevel programming for modeling the environment incorporating the role of central authority. After obtaining single level equivalent formulations of the problems, we analyze and solve them as non-linear programs. Our first problem is to analyze an intervention strategy, which uses only subsidy issued per unit order quantity. We explore the subsidy design problem for single retailer and n retailers cases. We show that all of the budget will be used under mild conditions and present structural results. Also, we analyze subsidy design problem for two echelon setting, where the central authority gives subsidy both to retailer and manufacturer. We consider centralized and manufacturer-driven problems and present numerical results. In the remaining part of the thesis, we focus on joint intervention mechanisms in which two intervention tools are applied simultaneously. First, we study a joint mechanism composed of demand-increasing strategy and rebate. We present two models and associated structural properties. First model aims to find optimal budget and allocation of it among intervention tools. We deduce that rebate amount may be independent of investment made in demand-increasing strategies and improvement pattern of demand. Second model decides on the optimal allocation of a given budget between intervention tools. We show that central authority will allocate all budget under mild conditions. Furthermore, we use real-life data and information of California electric vehicle market in order to verify the proposed models and show benefits of taking such an approach. We also explore the application of the joint mechanism under a given budget for exponentially distributed demand family and fully characterize the optimal solution. The analysis of the solution reveals that designing an intervention scheme without considering an explicit budget constraint will result in budget deficit and excess money transfers to the retailer. As the second modeling environment we consider a joint mechanism consisting of demand-increasing strategy and yield-improving strategy in a setting where yield uncertainty exists. We introduce lognormal demand and yield models that take into account the investments made for improving them. We test the suggested model with a case study relying on the available estimates of US influenza market. The results indicate that addressing both demand and yield issues by the proposed mechanism will increase vaccination percentages remarkably.Item Open Access Effectiveness of information systems outsourcing: An exploratory case study(IADIS, 2012) Uçar, Erkan; Bilgen, S.The objective of this research is to construct an assessment model for measuring the effectiveness of Information Systems (IS) outsourcing. "Lack of expertise" and "cost effectiveness" constitute the major points of motivation for IS outsourcing. Although various decision models and analytical frameworks have been modeled before, the literature is not abundant on a complete qualitative model. In contrast with the decision models which are executed before an outsourcing engagement (a-priori), an effectiveness assessment model will be an a-posteriori guide which will enable the clients to measure their outsourcing performance and re-evaluate their business and management strategies. This paper examines the factors for outsourcing effectiveness through the framework of an exploratory case study for an IS developed by a major Turkish software house for a public organization. © 2012 IADIS.Item Open Access Fractioning the refugee label – a case study of Syrian refugees in Turkey(2019-08) Qureshi, TazeenThis research analyzes Turkey‟s national asylum policies to determine if they result in the fractioning of the refugee label – as theorized by Roger Zetter. Fractioning of the refugee label occurs when states utilize legal and bureaucratic measures that are based on arbitrary or discriminatory requisites to restrict and exclude selected individuals from claiming unconditional refugee status within their territory. Refugees who suffer the consequences of disjunctive labels are unable to obtain legal status in the host country, unable to permanently settle or integrate in host society, and cannot avail the full gamut of rights accorded to them by the 1951 Refugee Convention – as in the case of Syrian refugees in Turkey. The question then arises as to why Turkey continues to host the largest refugee population in the world since 2013, even when it does not legally recognize Syrians as refugees and has no obligation towards them under the 1951 Refugee Convention. One finding is that Turkey‟s approach towards the Syrian refugee crisis has been somewhat myopic since the beginning. This is evident from Turkish government‟s changing stances on Syrian „guests‟ and the impromptu laws that have been adopted since 2011. A second finding is that Turkey continues to host Syrian refugees for opportunistic foreign policy reasons. This is evident from Turkey‟s recent bout of „refugee rentierism‟ – as theorized by Gerasimos Tsourapas – where Turkey is using its geo-strategic location and its large refugee population as a resource to extract strategic rent from the European Union through blackmail.Item Open Access Mapping out socio-cultural transformations through food packaging design in Turkey : a case study(2005) Karamullaoğlu, NazifeExploration of the impact of socio-cultural transformations in the development of food packaging design and brand identity in Turkey, in the post-1980 period, is the focus of this research. Accordingly, this thesis explores the related and broad issues of modernization and convergence; globalization, consumption contexts and culture; internationalization of retailing; postmodernism and aestheticized (conspicuous) consumption in parallel with developments in food packaging design and brand identity. All these are tied and analyzed in a case study where in the collected samples, developments in domestic and foreign food packaging design and the corresponding brand identities are socio-semiotically related to the transformations in socio-cultural context in Turkey. Socio-semiotic method of analysis, along with visual style analysis, has provided a study of images in their social and material context which is in accordance with this field of research.Item Open Access Marketing manufacturing interface in Biltepe AS(1996) Ayırga, A. OğuzMarketing manufacturing interface in Biltepe Inc. is analyzed by a qualitative research tool in this thesis.

Inadequate coordination between these two departments can be originated from various factors. The study determines the factors that have effect on the marketing manufacturing interface and provides an empirical case study by applying research tool in a manufacturing organization in the advanced construction materials industry. The study also includes analysis of the company related issues which have been scrutinized from a strategic perspective. In the final part recommendations made for future use of both this company and this study.Item Open Access Student perspectives on sustainability in engineering education: multiple case study of european bachelor's programs in industrial engineering and management(ARROW@TU, 2023-10-10) Trigueiros, Francisca; Kaipainen, Jenni; Silva, Frederico; Geising, Niklas; Tosun, Erdem AtaThe global sustainability crisis is calling for engineers to take action. To enable and empower engineers to address this crisis, there must be a change in engineering education. Given the industry's key role in not only causing but also solving this sustainability crisis, it is especially crucial to improve how sustainability is addressed in industrial engineering and management (IEM) education. This paper examines (1) to which extent European IEM degrees are covering sustainability; (2) European IEM students’ motivations to learn and work with sustainability topics; and (3) their perceptions of their degree’s contribution to their knowledge and motivation regarding sustainability; and (4) which sustainability-related changes they would like to see in their degrees. Three IEM curricula covering different regions of Europe—Portugal, Germany, and Turkey—were analysed. The mixed-method analysis included a quantitative evaluation of the extent to which each course meets specific theory-based learning objectives pertinent to sustainability in engineering education. The analysis was complemented by students’ perspectives, which were gathered through group discussions and interviews. The results reveal how sustainability is addressed in IEM education in different European regions, its impact on students’ knowledge and motivation for sustainability issues, and how sustainability in engineering education should be developed based on students' perceptions. These findings contribute to the research on sustainability in engineering education and support university teachers in revising engineering study programs to provide adequate sustainability understanding and skills to students.Item Restricted The Abundance of Solutions: Some Thoughts for Theoretical and Practical Solution Seekers(1982) Meindl, James R.
