A CLUB BELONGS TO A CITY- A REGION- AND A COUNTRY: ATHLETIC CLUB DE BILBAO
(ISTANBUL UNIV PRESS ISTANBUL UNIV RECTORATE, 2021) Mertcan Akan; Zaloa Zabala Inchaurraga; Akan, Mertcan; Zabala Inchaurraga, Zaloa; M Unver; M Tanriverdi
Euskal Herria which means Basque country refers not only to a geographical region but also to a society culture and thought. The Civil War that took place in Spain between 1936-1939 and the following Franco period (1939-1975) have played a critical role in shaping the memory of the Basque society and forming the present identity. The city of Bilbao which is the center of the country's largest region Bizkaia (Vizcaya) is also one of the places where the Basque identity and memory are being lived and kept living densely. The post-Franco period and the flood disaster in 1983 triggered a social cultural artistic and architectural transformation process in Bilbao city throughout which the city left its idyllic and industrial identity behind. This experience made Bilbao one of the most specific examples of how a city can be transformed by adhering to its historical origins. The purpose of this article is to emphasize the active role played by the Athletic Club one of the most important clubs in the institutionalization of modem football in Spain and how a sport club is owned by a city and its society. Carrying out a rare policy in contemporary industrial football with the mission of being the representative of the Basque country the club continues its struggle with athletes trained mostly from quarry. In this sense Athletic Club managed to bring the local struggle of its own lands together to a global stage. Thus as a sport club the Athletic Club has been = so effective in the information of identity and city culture that it has become one of the rare examples of this in the world.

A Conceptual Framework for Food Loss and Waste in Agri-Food Supply Chains: Circular Economy Perspective
(Springer, 2021) Yasanur Kayikci; Nazlican Gozacan; Çisem Lafci; Yigit Kazancoglu; Kayıkcı, Yaşanur; Gözaçan, Nazlıcan; Lafcı, Çisem; Kazançoğlu, Yiğit
The importance given to Circular Economy (CE) has further increased in the Agri-Food Supply Chain (AFSC) to combat the challenges of food loss and waste which could be caused by various reasons such as poor stock management economic behavior and also the occurrence of COVID-19 outbreak. The transition from linear to circularity can also enable competitive sustainability from farm to fork in AFSC which consists of different stages: farmers food processors food distributors food retailers consumers. Food loss mainly occurs in AFSC at near-farm stages (i.e. harvesting processing) while food waste happens in AFSC at near-fork stages (i.e. retail post-consumption). Thus 6Rs (remanufacture redesign reduce recycle reuse and recover) of CE principles can offer various benefits to close the loop of the wastages along with the AFSC. In this chapter a conceptual framework for circularity in the AFSC is proposed considering the 6Rs. Furthermore this framework also supports the Sustainable Development Goals. The applicability of the proposed framework is examined and discussed in the case of Turkey using SWOT Analysis. Key findings indicate that there is confusion about food loss and waste issues in Turkey. In addition the solutions and developments for FLW problem are generally focused on food waste. © 2021 Elsevier B.V. All rights reserved.

A differential evolution algorithm with a variable neighborhood search for constrained function optimization
(Springer Verlag service@springer.de, 2015) M. Fatih Tasgetiren; Ponnuthurai Nagaratnam Suganthan; Sel Ozcan; Damla Kizilay; Tasgetiren, M. Fatih; Suganthan, P.N.; Kizilay, Damla; Ozcan, Sel
In this paper a differential evolution algorithm based on a variable neighborhood search algorithm (DE_VNS) is proposed in order to solve the constrained real-parameter optimization problems. The performance of DE algorithm depends on the mutation strategies crossover operators and control parameters. As a result a DE_VNS algorithm that can employ multiple mutation operators in its VNS loops is proposed in order to further enhance the solution quality. We also present an idea of injecting some good dimensional values to the trial individual through the injection procedure. In addition we also present a diversification procedure that is based on the inversion of the target individuals and injection of some good dimensional values from promising areas in the population by tournament selection. The computational results show that the simple DE_VNS algorithm was very competitive to some of the best performing algorithms from the literature. © 2015 Elsevier B.V. All rights reserved.
A HOLISTIC APPROACH AND A SYSTEMATIC MODEL SUGGESTION FOR STREET ECONOMY
(EMERALD GROUP PUBLISHING LTD, 2021) Isil Kellevezir; Kellevezir, Isil; S Grima; O Sirkeci; K Elbeyoglu
All sectors have been affected economically due to the COVID-19 epidemic that we have experienced since the beginning of 2020. As a natural reflection of this we know that unemployment is rising. The street economy is both a shelter for the workforce pushed from other sectors and for the existing workers. However we do not know much about the current situation and problems of this industry all over the world. Of course the investment required to determine with full accuracy the components of the street economy (how many people where they work and what are the characteristics of these people) which have a very dynamic structure are usually based on social needs is very large. However by photographing the street economy on a regional basis today the need to regulate this sector which has more impact on the mental and physical health of both the individual and society than ever before is strongly manifested. In this study a systematic layout proposal was tried to be proposed for this arrangement.

A Variable Block Insertion Heuristic for the Energy-Efficient Permutation Flowshop Scheduling with Makespan Criterion
(Springer Science and Business Media Deutschland GmbH, 2021) M. Fatih Tasgetiren; Hande Oztop; Quanke Pan; Mustafa Arslan Ornek; Talya Temizceri; Tasgetiren, M. Fatih; Temizceri, Talya; Oztop, Hande; Pan, Quan-Ke; Ornek, M. Arslan
Permutation flow shop scheduling problem is a well-known problem in the scheduling literature. Even though various multi-objective permutation flowshop scheduling problems have been studied in the literature energy consumption consideration in scheduling is still very seldom. In this paper we consider a bi-objective permutation flowshop scheduling problem with the objectives of minimizing the total energy consumption and the makespan. We present a bi-objective mixed integer programming model for the problem applying a speed-scaling approach. Then we employ the augmented ε -constraint method to generate the Pareto-optimal solution sets for small-sized instances. For larger instances we use the augmented ε -constraint method with a time limit on CPLEX solver to approximate the Pareto frontiers. We also propose a heuristic approach which employs a very recent variable block insertion heuristic algorithm. In order to evaluate performance of the proposed algorithm we have carried out detailed computational experiments using well-known benchmarks from the literature. First we present the performance of the proposed algorithm on small-sized problems, then we show that the proposed algorithm is very effective to solve larger problems as compared with the time-limited CPLEX. © 2020 Elsevier B.V.

Account portfolio management: Optimizing the customer portfolio of the firm
(wiley, 2015) Osman Gök; Gök, Osman
The account portfolio management (APM) process deals with grouping customers and developing meaningful strategies for each group incorporated into resource allocation decisions to meet marketing objectives. Portfolio techniques offer a convenient and comprehensible framework for strategic decision-making. This paper presents a comprehensive guide to developing customer portfolios using variables identified in previous studies. The paper also illustrates implications for marketing strategies and future resource allocation for the strategic account portfolio. A portfolio approach may reveal necessary actions for important relationships and may streamline the decision-making process for suppliers' account portfolios. Each customer relationship requires different types and degrees of investment and produces different outcomes (Cannon and Perreault 1999). Hence the paper emphasizes customer heterogeneity in the business-to-business (B2B) marketing context and arrives at sound evaluations of individual customers. © 2023 Elsevier B.V.

Adaptive Reuse of Existing Buildings
(Springer Science and Business Media Deutschland GmbH, 2025) Maria Beatrice Andreucci; Selin Karagözler; Andreucci, Maria Beatrice; Karagözler, Selin
Amid the introduction of the United Nations’ Sustainable Development Goals the longevity and lifecycle of heritage and modern buildings and the process of redevelopment have come under greater scrutiny. Through adaptive reuse i.e. changes that involve both a functional and a physical component practitioners can give a second life to existing buildings. To define the state of the art in the scientific research focused on building adaptive reuse the authors conducted a rapid evidence assessment. It emerged that adaptive reuse is comprehensive topic that deals with social economic and environmental issues. The goal of the adaptive reuse studies varies from social to environmental topics such as human-centred adaptive reuse and energy efficient adaptive reuse. A comprehensive approach to adaptive reuse requires integrated strategies aimed at preserving valuable pre-existing human artifacts in the Anthropocene era characterized by unsustainable consumption and transience of data and images. Adaptive reuse combines pragmatism and creativity and requires sensitivity in the selective approach on existing structures contexts and materials. Adaptive reuse projects call for specific skills and targeted strategies that falls into different action categories: reuse restoration and renewal i.e. innovative transformations of the “old and degraded” into “new and performative”. Overall adaptive reuse optimizes environmental sustainability efficient regeneration processes increased community interest and profitability making it an attractive opportunity for stakeholders seeking to revitalize urban and peri urban areas. Adaptive reuse projects deliver workable solutions support heritage and cultural preservation while meeting the changing needs of communities. © 2024 Elsevier B.V. All rights reserved.

Additive manufacturing and its impact on pharmaceutical supply chains
(Elsevier, 2024) Wenqi Li; Banu Yetkin Yetkin Ekren; Emel Aktas; Li, Wenqi; Aktas, Emel; Ekren, Banu Y.
Additive manufacturing (AM) also known as 3D printing has the potential to improve the performance of the pharmaceutical supply chain (PSC). By using 3D printing for manufacturing drugs pharmaceutical companies can reduce waste by using only the required number of raw materials and eliminating excess inventory. This chapter will provide a systematic literature review of the state of the art of AM in PSC and develop a conceptual framework to explain their interconnections. It was found that 3D printing impacts the SC in three main ways: reducing complexity moving manufacturing facilities closer to the end user and shifting production from make-to-stock to make-to-order. These changes influence the inventory level which in turn affects SC sustainability efficiency responsiveness and resilience. This study provides a conceptual framework that illustrates the interrelationships between various variables in the medical SC impacted by 3D printing technology. © 2024 Elsevier B.V.

Graphical user interfaces (GUIs) enable comfortable interactions of the computer-based systems with their environment. Large systems usually require complex GUIs which are commonly fault prone and thus are to be carefully designed implemented and tested. As a thorough testing is not feasible techniques are favored to test relevant features of the system under test that will be specifically modeled. This chapter summarizes reviews and exemplifies conventional and novel techniques for model-based GUI testing. © 2017 Elsevier B.V. All rights reserved.

Alternative measures of currency and asset substitution: The case of Turkey
(Anthem Press, 2010) Ayşe Özden Birkan; Birkan, A. Özden
Like many developing countries that liberalized their capital account Turkey has been at the mercy of short term capital inflows accompanied by a continuous real appreciation of the domestic currency since 1989. Open foreign exchange positions and increasing foreign exchange related assets in residents’ portfolios have been the inevitable side affect. The recent inflation targeting policy is claimed to have reversed this trend. However the currency substitution measure developed in this study suggests an alternative interpretation of the situation. Although the share of TL denominated assets in total monetary assets has been increasing relative to the share of foreign currency related assets the liquidity services of TL denominated assets is in fact not increasing. In this study distinct measures of asset substitution and currency substitution as opposed to the generic FCD/M2Y are developed and the different degrees of liquidity provided by alternative monetary assets are distinctly measured. These AS and CS measures follow the conventional intuition as to their driving factors and suggest the existence of hysteresis in currency substitution in Turkey. From a policy standpoint this provides evidence that targeting and decreasing the inflation rate alone may not be sufficient to overcome the structural problems of the economy that have been in the making for decades. © 2015 Elsevier B.V.

Inventory management is one essential lever to use the resources efficiently. However managing inventories in hospitals is a challenging task because of the several issues: a high service level of medical supplies is required under the unpredictable demand medical products constitute a significant portion of the overall costs and the management of these supplies requires considerable effort to check the levels to track usage and to distribute them. Therefore it is pertinence to apply operations research tools to cope with the managerial issues of the hospital inventory system. In this chapter the authors implement an (s S) inventory model by using simulation in a case study of a hospital in Izmir Turkey. They aim to analyze the unpredictable nature of demand of medical supplies in this hospital and its implications on the developed inventory policy. © 2022 Elsevier B.V. All rights reserved.

An Analysis of Corporate Social Responsibility in the Turkish Business Context
(Springer Nature, 2015) Duygu Türker; Turker, Duygu
Depending on the increasing social and environmental problems corporate social responsibility (CSR) has been promoted by both national and international bodies to achieve the principles of sustainable development at the organizational level. Since the concept has provided a significant framework for the relations between business and society this corporate response can be particularly crucial for the problems in the developing country context. Therefore it is important to understand how CSR is adopted and practiced by the organizations in such countries to improve the overall quality and quantity of CSR involvement. The purpose of current study is to analyse the evolution of CSR conception in Turkey as a developing country. Considering its unique position between East and West Turkey provides a different political economic social and cultural context for CSR conception than other European counties. The concept has built on the philanthropic heritage of Ottoman period and then evolved in line with the dependency relationship between business and state during the Republican period. Despite the increasing attention of organizations towards CSR during the last decade it seems that the institutional environment continues to affect the nature and structure of CSR involvement in Turkey. © 2022 Elsevier B.V.

AN ASSESSMENT OF INNOVATION EFFICIENCY IN EECA COUNTRIES USING THE DEA METHOD
(EMERALD GROUP PUBLISHING LTD, 2020) Rustem Baris Yesilay; Umut Halac; Halac, Umut; Yesilay, Rustem Baris; S Grima; E Ozen; H Boz
Introduction - In recent years there has been a growing interest in innovation not only in developed countries but also in developing countries. However there has been limited literature for the developing countries. Purpose - The literature on national innovation systems (NIS) mainly consists of case studies or qualitative researches aiming to explain the patterns of innovation while the quantitative analysis are limited in explaining the innovation capability and efficiency of innovation. This study is unique in a sense that it compares the innovation efficiencies of the EECA countries. This chapter aims to measure the efficiency of NIS via data envelopment analysis (DEA) method. Methodology - DEA is used to consider a sample of 18 Eastern European and Central Asian (EECA) countries and Turkey. One of the main issues is to determine the input and output variables because the available data for some of these countries were limited. Therefore research and development expenditure (% of GDP) government expenditure on education total (% of GDP) imports of goods and services (% of GDP) and foreign direct investment net inflows (% of GDP) were determined as input variables. Output variables were as follows, patent applications both residents and non-residents high-technology exports (% of manufactured exports) and scientific and technical journal articles. Findings - Based on the key findings it can be noted that Kazakhstan Turkey Latvia and Uzbekistan are more efficient in innovation performance compared to other EECA countries. Throughout the results of the DEA these countries may develop new policies about their innovation systems to reach out the higher performance.

An evaluation of measuring the publicness level of interiors in public building design: Visual Graph Analysis (VGA) approach
(IGI Global, 2021) Pelin Aykutlar; Seckin Kutucu; Işın Can-Traunmüller; Can-Traunmüller, Işin; Kutucu, Seçkin; Aykutlar, Pelin
This study examines the publicness level of the interior spaces of public buildings. As a method VGA (visual graph analysis) is used for analyzing the early design phases of selected municipal service buildings. In this study the authors utilized from VGA for quantifying the publicness level of the two selected architectural competitions of municipality buildings. The method allows us analyzing the floor plans of each project in obtaining an eventual assessment of permeability and accessibility which give an idea of the levels of publicness comparatively. Subsequently representation parameters are compared under two main criteria: connectivity and integration. The aim of the study is to understand the level of publicness and efficiency of spatial settings for the users circulating in the public buildings which have dissimilar plan schemes. This method would be used by the designers for early design stage and provide useful feedback for understanding the level of accessibility and permeability of the structures and adjust their schemes accordingly. © 2022 Elsevier B.V.

An overview of international fintech instruments using innovation diffusion theory adoption strategies
(IGI Global, 2020) Ebru E. Saygılı; Tuncay Ercan; Ercan, Tuncay; Saygili, Ebru
The aim of this chapter is to evaluate and predict the future of international fintech instruments in the domain of innovation diffusion theory (IDT) adoption strategies. Further the consequences of the new payments system directive (PSD2) in Europe and blockchain applications are discussed. For instance money transfer and payments have the highest rate of adoption (ROA) while insurance services have the highest speed of growing ROA due to relative advantages high compatibility and trialability levels and low level of complexity and uncertainty. Cross country comparisons include descriptive statistics about fintech deal value and volume innovation rank B2C commerce market ROA and internet penetration. Germany is the only country listed in all of the top 10 ranking lists followed by the U.S. the U.K. and France. Also China India and Canada have distinguished success in terms of fintech indicators while the growth in Japan is expected to be slow. Accordingly ROA in five emerging markets is much higher than some of the developed countries which can be explained by the Cancian Theory. © 2022 Elsevier B.V. All rights reserved.
