Assessment of a Multidimensional Job Satisfaction Instrument
(Elsevier Science Bv, 2015) Özpehlivan, Murat; Acar, A. Zafer; Uluslararası Lojistik ve Taşımacılık / International Logistics and Transportation
The job satisfaction concept has been attracting the attention of researchers and executives because of its influence on individuals' behaviour. The individual's behaviours are shaping organizational behaviours through groups within the organization and the organizational culture. The effects of job satisfaction on the different organizational behaviours have been tested and proven in myriad researches but using different methods and measurement instrument including various dimensions show us that there is no certain consensus of measuring at least basic components of this concept. This study aims to fill this gap through conceptualizing, measuring the concept on basic and necessary factors and developing a multidimensional job satisfaction measurement instrument by considering cultural affect. The questionnaires that using only by translating from another countries or cultures and if their cultural differences are not taken into account then obtained results may not give us accurate values and damages the validity of the scales. We established a scale incorporating six dimensions of job satisfaction. 699 data were then collected from Turkey and Russia's well-known businessmen associations in textile field and analysed through confirmatory factor analysis to assess validity and reliability. As a result, we have attempted to contribute to business executives and academics by providing a multidimensional job satisfaction scale.

Development and validation of a multidimensional job satisfaction scale in different cultures
(Taylor & Francis As, 2016) Özpehlivan, Murat; Acar, A. Zafer; Uluslararası Lojistik ve Taşımacılık / International Logistics and Transportation
Pioneer studies towards the definition of the concept of job satisfaction are based on the beginning of the 20th century. Since its presentation, this concept has been attracting the attention of researchers and executives because of its influence on individuals' behaviour in organizations. The effects of job satisfaction on the various concepts has been tested and proven in myriad researches. However using diverse measurement instruments including many different dimensions show us that there is no certain consensus of measuring at least basic components of this concept. Today, much of the used questionnaires coming from the developing countries and reflecting the employee behaviour of Anglo-Saxon cultures. By translating those questionnaires without considering their cultural differences, of course, may not give us accurate results and damaging the validity of the scales. This study aims to fill this gap by measuring the concept on the basic and necessary factors, and developing a multidimensional job satisfaction scale reckoning with cultural effect. As a consequence of our extensive literature scanning, we established a scale incorporating six dimensions of job satisfaction concept. 699 data were collected from Turkish and Russian well-known businessmen associations in textile field and analysed through confirmatory factor analysis to assess validity and reliability. The data that obtained generally from the SMEs and basically/mentally from two different developing countries forefront the cross-cultural dimension of the research. As a result of the analysis, we have attempted to contribute to business executives and academics by providing a multidimensional job satisfaction scale.

EVALUATING THE LOCATION OF REGIONAL RETURN CENTERS IN REVERSE LOGISTICS THROUGH INTEGRATION OF GIS, AHP AND INTEGER PROGRAMMING
(Univ Cincinnati industrial Engineering, 2015) Acar, A. Zafer; Onden, Ismail; Kara, Karahan
Reverse logistics network problems are accepted as sophisticated research areas in the existing literature due to difficulties of the prediction of the material flow in the network and the conflicting objectives of minimizing total cost and energy consumption while maximizing customer satisfaction and control of the pollution. There are different approaches to dealing with the difficulties of the problem, yet these approaches overlook the geographical aspect of the issues. In this paper, a reversed network of a governmental organization is evaluated. A methodology is proposed that integrates Analytic Hierarchy Process, Geographic Information Systems and integer programming to determine the locations of the return centers and to deal with the complicated structure. Population, airport locations, maritime facilities, railroad lines and highway lines are accepted as the decision criteria. Based on these decision criteria, suitability levels of the candidate cities are calculated. A closed-loop supply chain is taken into consideration and reverse functions of the chain are evaluated with the proposed methodology.

XXI century is witnessing the rise of innovation and innovativeness as one of the main drivers of industrial competition. Innovation becomes increasingly crucial in creating and maintaining an organization's competitive advantage, as well as its contributions to growth and wealth [i]. In other words innovation itself is a strong competitive strategy to achieve world-class manufacturing and servicing status and compete effectively in global markets [ii]. Learning capabilities of a firm in context of knowledge management are claimed that as one of the main drivers of innovativeness. Even there are some efforts to consider these concepts together; they are mostly studied as separately in today's "management theory jungle". Thus, this paper aims to offer a holistic approach for building organizational innovativeness on the basis of Knowledge Management (KM) and Organizational Learning Capabilities (OLC).

Talep planlamanın müşteri ve tedarik zincirine etkilerini düzenleyen bir yapı ve örnek uygulaması
(2015) Yılmaz, Behlül; Acar, A. Zafer
Küçük, orta ve büyük ölçekli işletmeler maliyetlerini minimum yapabilmek için eldeki kaynaklarını uygun şekilde kullanmalıdır. Bunun için yapılan planların, gerçeğe en yakın şekilde hazırlanması önemlidir. Ayrıca işletmeler çalışmalarının sürdürülebilir olması için, bugünü değil geleceği de planlamalı, stok maliyeti, işgücü, zaman, finans gibi kaynaklarını en iyi şekilde yönetebilmek ve fireleri önlemek maksadı ile gerekli tedbirleri almalıdırlar. Talep tahmini sistemleri, şirketlerin değişen pazar şartlarına kolayca ayak uydurabilmelerini sağlamanın yanında, stratejik ve yönetsel düzeyde planlamaları ile operasyonel uygulamalarında kolaylık sağlamaktadır. Talep tahmini performansı düştüğünde, müşteri taleplerinin zamanında karşılanma oranı düşer. Bunun sonucunda şirketler hızlandırılmış, sonucu çabuk alınabilen hizmetlere ve diğer pahalı aksiyonlara yönelirler. Yapılacak kısa ve uzun vadeli planların başlangıç noktası, talep tahminidir. Ayrıca uzun dönemli planlarda sapmaların yüksek olması sebebi ile yapılan planların kontrol sıklıkları ve yöntemlerinin belirlenmesi, başarılı bir talep tahmin sistemi için, çok önemlidir. Bu çalışmada talep tahmini ve planlamasının, üretim planlarının ilk aşaması olduğu gerçeği ile birlikte, müşteri ve tedarik zinciri halkalarını oluşturan tüm süreci nasıl etkilediği anlatılmaya çalışılmıştır. Yürütülen bu çalışmada nicel ve nitel talep tahmini yöntemleri incelenmiş, en uygun yöntemin belirlenmesi üzerine durulmuş ve doğru sonuca en yakın tahminler elde edilmeye çalışılmıştır. Belirlenen yöntem, bir planlama uygulaması ile desteklenerek sürecin takvimi ve çalışma şekli yeniden belirlenmiştir. Anahtar kelimeler: Talep, Tahmin, Planlama, Tedarik Zinciri Yönetimi
