A six sigma case study in a large-scale auto motive supplier company in Turkey
(2012-01-10) Tanık, Murat; 143629
Although six sigma is a really effective methodology with its strong data-based decision-making aspect, there are many obstacles and factors that weaken the effectiveness of the projects. This fact is even more obvious in the heavy industry, especially in developing countries such as Turkey, where statistical insight is not very common and systematic approaches are often neglected. Belief systems, culture, knowledge level of data-based decision-making or to put it simply, human factor and its management are the most crucial factor for success. Different cultures and different work environments impose the need for discovering new ways for altering the beliefs and improving the motivation of the project participants. The responsibility of changing the perception of team members lies on the shoulders of quality leaders. The purpose of this study is to highlight some important points that can contribute to the success and effectiveness of future six sigma programmes via data obtained from a number of projects that were carried out in a large automotive supplier in Izmir, Turkey. The authors participated in the programme as project consultants and authors’ observations from management meetings, training courses, and the project meetings are reflected and many key findings are mentioned in the paper.

Additive Production as Metamorphosis in Production Morphology
(2019-12) Alçın, Sinan; 9467
Production as a live process, describes a flow in which different components come together in different shapes and quantities into a different new component. Production in its simplest form involves the effort to bring out something new, while in another aspect it is a process of extracting mineral from the soil, water from the river, and oxygen from the air. In the manufacturing stage of production, there are three classical methods: Cutting, Engraving and Forming. All three of these methods include cutting, engraving and shaping the mine or compound drawn from soil, air and water. The production compound detached from nature experiences the second intervention in the manufacturing stage. This metazori is a metaphormosis. In recent years, Additive Manufacturing has entered our agenda with three- dimensional printers and scanners, unlike classical production and manufacturing methods; with a wide range of material combinations using very different techniques (FDM, SLA, DLP, SLS etc.) production from the current state, it is based on the idea of integrating the fragmented state of the present. Additive Manufacturing enables product possibilities such as iron powder motor housing or a jointless table, the main purpose of this study is to discuss how differentiated from current production.

(IJOPEC Publication Limited, 2018-04) Dereli, Deniz Dilara; Sağlar, Uğur; 112577
Today, Industry 4.0 triggers a significant transformation process in macro scale. Countries seeking to increase production, productivity and growth rates find themselves in a different and rapid competition under the new conditions created by the new generation production systems. It is expected that the intelligent production processes comprising innovative elements such as big data, cloud, industrial internet, autonomous robots, etc., will provide economic benefits such as increase in productivity, decrease in cost, more flexible production structures and high market shares. In this respect, Industry 4.0 can be a tool in order to transform Turkey’s own economic dynamics paving the way to a structural change. This article attempts to explain current position of Turkey in Industry 4.0 processes and discusses the structural reforms required for Turkey’s economy to adapt itself to the intensifying global competition.

(BILGESEL YAYINCILIK SAN & TIC LTD, KUSKONDU SOKAK KILIM APT 14-8, A AYRANCI, ANKARA, 06550, TURKEY, 2009-11) Eser, Rüya; Kırer, Hale; TR23951
From the relationship between economics and physics to econophysics This paper is intended to review the literature investigating the interaction between physics and economics, The relationship between these two disciplines has been a repeated topic in the history of science, and recently the interaction between the two fields has been renewed by several new findings of physicists working on problems in social science. Econophysics, known as an interdisciplinary field of research, was born in 1995 and has grown extensively over the last decade. In this paper, after providing a definition and a brief historical background of econophysics, a summary of some applications of models and methods of statistical physics to economic problems are introduced Furthermore the study, based on a survey of the relevant literature, maintains that the methodology of econophysics has its own weaknesses.

Further education or re-enlistment decision in Turkish armed forces: A seemingly unrelated probit analysis
(Taylor & Francis Ltd, 4 Park Square, Milton Park, Abingdon Ox14 4Rn, Oxon, England, 2010) Yıldırım, Juelide; Karasu, Şemsettin; GÜMÜŞOĞLU, NEBİLE KORUCU; 115505
Previous empirical studies examining the determinants of re-enlistment probabilities have generally employed a univariate approach and have suggested that expected further education increases the likelihood of joining the army. However, the re-enlistment and further education decisions can be interdependent. Accordingly, this study employs a seemingly unrelated bivariate probit model to jointly estimate the factors that influence both further education and re-enlistment decisions. Empirical analysis indicates that there is a correlation between the re-enlistment and further education decisions, revealing that previous single equation models might be misspecified. Moreover the geographical background, education level of the conscript, intention of further education and previous unemployment duration are influential in the re-enlistment decision. Additionally, the further education decision appears to be determined by family and sibship characteristics, education level and age.

Impact of High Technology Export on Economic Growth: An Analysis on Turkey
(2019-06-21) Erdil Şahin, Begüm; 112240
High-technology exports, with their high added value, are considered as one of the determinants of growth in recent years. The increasing competitiveness of developing countries in international markets depends on the country's capacity to produce and export high-tech products. Therefore, the export of high technology products is especially important for the economic growth and development of the countries. After 1980, Turkey has transitioned from import substitution to export-oriented industrialization strategies and largely completed the liberalization process during 1990s. Important policies for industrialization have been implemented by improving the export structure within the scope of competitive advantages. In this study the effects of the causality analysis on the economic growth of high-tech exports in Turkey has been investigated. Granger Causality Analysis was used to determine the direction of the relationship and the results of the variance decomposition were evaluated. In conclusion, it was found out that high technology exports affect economic growth.

Importance of Technology, Innovation and R&d In Increasing The Competitive Capacity of SMEs In Turkey
(International Finance Banking & Insurance Congress, 2012-04-18) Erdil Şahin, Begüm; Dündar, Efe; 112240; 165449
Small and Medium Enterprises (SMEs) have significant contributions to economic growth due to their flexible structures which help them develop technology and adapt to the rapidly changing market conditions in the condensing competition atmosphere as a result of globalization. Within this framework, SMEs have a significant role in increasing employment, investments, and export all around the world as well as in Turkey. It is necessary to develop new technologies and produce by using new methods in order to have and maintain a superior position in competition. SMEs started to become committed to research and development (R&D) activities especially in recent years. However, one of the most significant problems SMEs is the lack of financing in developing new technologies and R&D activities. A number of organizations in Turkey support SMEs in order to form highly innovative SMEs which are strong in international markets. Furthermore, with the incentives and policies executed, competitive capacities of SMEs are supported. The objectives of this study are to present the importance of technological innovations and R&D for SMEs in Turkey as essential factors of compatibility. Within this framework, this study deals with the notion and definition of SMEs in Turkey and in the European Union, place and importance of SMEs in the economy, and the problems that SMEs experience. Furthermore, after presenting the importance of technology, innovation, and R&D for compatibility of SMEs, the problems regarding R&D activities, the supports and policies for increasing the competition capacity in Turkey and finally the supports supplied in the European Union are evaluated.

Innovation management in global competition and competitive advantage
(Elsevier Science Bv, Sara Burgerhartstraat 25, Po Box 211, 1000 AE Amsterdam, Netherlands, 2015-05-28) Dereli, Deniz Dilara; 112577
Increasing competition due to the liberalization of world trade has led to the production of goods and services according to new needs arising in the global market. Obtaining an advantageous position in the global competitive environment depends on determining right strategies and creating different values. Dynamic market structure, differing market conditions and the existence of innovative competitors make competition even more intense. Nowadays, objectives such as increasing productivity and profitability, gaining new markets and improving existing market shares are reached through innovation activities. Therefore, companies exert themselves to develop innovative skills, gain sustainable abilities and upgrade their performances. In this context, innovation has been one of the essential elements of competitive advantage. New goods and services must be produced in new ways and by adapting the inside and outside applications to the new developed methods, the organizational processes must be restructured. Not only to produce new goods and services, it is also important to manage it as a process. For determination of innovation performance, it is very significant to address all the factors affecting the innovation management process with a holistic approach. While rightly determining needed technology and management stands out as an important element of innovation management, the human and structural adjustment of the organization is also gaining importance in innovation performance. In the global competitive environment, organizational and managerial innovations are the keys to success for companies. While technology and research and development activities significantly influenced the organizational structure and culture, right innovation management provides a competitive advantage. This study aims to evaluate the impact on the competitive advantage of innovation management by putting out the importance of innovation management. (C) 2015 The Authors. Published by Elsevier Ltd.

Institutional Determinants Of Sectoral FDI In Eastern European And Central Asian Countries : The Role Of Investment Climate And Democracy
(M E Sharpe Inc, 80 Business Park Dr, Armonk, Ny 10504 Usa, 2012-12) Doytch, Nadia; Eren, Mesut
We study the determinants of the sectoral distribution of foreign direct investment (FDI) in Eastern Europe and Central Asia, focusing on the investment climate and state of democracy. Using a dynamic system generalized method of moments estimator, we examine twenty-one countries for the period 1994-2008. We find that when human capital is controlled for, the host country investment profile has a positive effect on agricultural FDI and the host country state of democracy positively affects agricultural and manufacturing FDI. In addition, services FDI is attracted by educated labor, whereas FDI to other sectors is attracted by cheap labor. Moreover, natural resource endowments have a positive impact on FDI in the sectors of agriculture and manufacturing.

Institutional quality similarity, corruption distance and inward FDI in Turkey
(Rainer Hampp Verlag, Meringerzellerstr 10, Mering, D-86415, Germany, 2015) Eren, Tevfik Mesut; Jimenez, Alfredo; 108275
In this paper we investigate the impact of institutional differences as a determinant of Turkish FDI inflows from OECD economies. We focus on the corruption distance between the home and host countries as a crucial part of institutional quality. Our results confirm that FDI flows are higher when they come from countries with low differences in corruption with Turkey. Conversely, FDI flows are negatively affected when there exists a large difference in corruption between the investing country and Turkey. This is explained by the ability of firms to obtain a higher return from their resources and capabilities in those environments with a similar idiosyncrasy to the one of their home country.

Mergers and Acquisitions Versus Greenfield Investment, Absorptive Capacity, and Economic Growth: Evidence from 12 New Member States of the European Union
(Routledge Journals, Taylor & Francis Ltd, 4 Park Square, Milton Park, Abingdon Ox14 4Rn, Oxfordshire, England, 2015-03) Eren, Tevfik Mesut; Zhuang, Hong; 108275
Using disaggregated FDI data on 12 new member states of the European Union from 1999 to 2010, this paper examines whether different types of FDI have differential effects on economic growth. Our results show that mergers and acquisitions (M&As) and greenfield investment do not on their own have significant growth effects in these economies. In both cases, the availability of absorptive capacity plays an important role in stimulating their growth effects. Moreover, a developed financial system complements the impact of M& As on economic growth, while a minimum threshold level of human capital needs to be reached so that greenfield investment is beneficial for economic growth. Domestic investment is revealed to be a consistent contributor to economic growth.

Opinions and Expectations of Student of Economics in a Turkish University
(2019-06) Özışık, Tuğba
With a population of more than 80 million, Turkey has a great number of young people wishing to get a university degree and have an edge in the competition for a job. However, to what extent they have a clear idea about the department they choose is a question mark. This study focuses on the opinions of 3rd grade university students in the Department of Economics at İstanbul Kültür University. It aims to compare the motivational factors through which these students decided to study Economics with their current points of view about this field of study. It also analyzes students' career expectations and beliefs about job opportunities after graduation. In order to gather data, students were given questionnaires and a descriptive analysis was carried out. In addition, a focus group meeting with the students was organized. Common themes emerged from the transcriptions of the meeting were supported by students' actual sentences. Findings reveal that a surprising number of students have different ideas from the time they started studying Economics, both from positive to negative and negative to positive, which might suggest that during the critical phase of choosing a career path, most students are not fully aware of what is waiting for them. Moreover, almost two thirds of the students do not have high hopes of getting a decent job due to the nonstable economy and the problem of unemployment in the country.
