Entrepreneurship is an important process in regional economic development. However, there is no dedicated research to determinants of entrepreneurship in relation to all regions of Turkey. The main objective of chapter is to find the extent to which the level of entrepreneurial activity varies between regions in Turkey. This chapter also contributes to the field of entrepreneurship studies by presenting, for the first time, the entrepreneurship data of women over the regions of Turkey and by analyzing the regional variations with respect to gender in the early stage of entrepreneurial activity. Our findings support the fact that the . . . entrepreneurial activity in the West Marmara, the Mediterranean, the West Black Sea and the West, Southeast and the Central Anatolia Regions, are no different from the base Region of Istanbul. The general entrepreneurship pursuit in Aegean, the East Marmara, the East Black Sea, the Northeast Anatolia and the Central East Anatolia Regions are found to be about 2% lower compared to the Region of Istanbul, on the average. On the other hand, the likelihood of being an entrepreneur among women is highest in the Aegean Region which is 9.4%. This likelihood is even higher than that in the Region of Istanbul which is 8.1%. Hence, the probability of being a woman entrepreneur ranges from 5.8 to 10.6% in Turkey. When the same probabilities are considered at the age of 45, they are lower and range from 5.4 to 9.7%. Moreover, while the entrepreneurial attitudes, i.e. fear of failure in starting business, and education have a negative effect, the perceptions on start-up opportunities and believed to have knowledge, skill and experience have a positive effect on the probability of being an entrepreneur. The data used in this study were collected by means of the national adult population Survey (APS) from the Global Entrepreneurship monitor (GEM) project conducted in Turkey covering the years of 2006–2015 (except for the year of 2009). The dataset consisting of 56,142 interviews with a representative sample of adults (18–64Â years old) covering 12 regions. © Springer International Publishing AG, part of Springer Nature 2018

Iran, Pakistan, and Turkey are the founding members of the Economic Cooperation Organization (ECO), established in 1985, to promote economic, technical, and cultural cooperation among the member states. The three countries share borders and have marked similarities in numerous cultural, religious, and traditional values. With a combined population of over 320 million and economies ranging from factor-driven to efficiency-driven, countries of Iran, Pakistan and Turkey, comprise more than half of the MENA region population. This project envisages a comparative study of women entrepreneurship in Iran, Pakistan, and Turkey using qualita . . .tive as well as quantitative approaches. Women entrepreneurship in these countries are studied from both domestic and international perspectives. © Springer International Publishing AG, part of Springer Nature 2018

This study introduces the usability of Balance Theory for the effective and correlated management of vision, strategies and projects especially in complex environments. Balance Theory was initially developed by Livvarçin (J Turk Navy Navy 77–81, 2010) as a tool for the strategic management of business organizations as well as national organizations or even countries. The theory basically claims that there should be a balance between the interest area of the organization and its power. Any misbalance between those two parameters will cause various types of strategic level problems. When the level of complexity increases, the establis . . .hment of clear vision, derivation of strategies and finally development of oriented projects becomes more crucial and more difficult. This study proposes the usage of balance theory for designing vision as the first step. It basically aims to answer the questions; “Where are we now?”, “Where do we want to be?” and finally “How shall we go there?” for the determination of the vision. In the second step; strategies will be developed by assessing the gap between our current and aimed positions. Afterwards, the most appropriate and feasible projects can be initiated. This straightforward process is valid also in complex environments where pursuit of strategies becomes more difficult. © Springer International Publishing Switzerland 2015

This paper uses complexity theory to help our understanding of the development of specific leadership characteristics that would be appropriate in today’s complex and turbulent environments. In terms of complexity theory complex systems accomplish harmony through uncontrolled interactions of various different agents. The consequences of these interactions are unpredictable (Plowman et al. Leadersh Q 18(4):341–356, 2007). In complex systems the leader’s responsibility is to incorporate interactions between agents that may occur in multi-dimensional processes (Avolio et al. Ann Rev Psychol 60(1):421–449, 2009; Taylor et al. Leadersh Q . . . 22(2):412–433, 2011). In complex environments, classical, top-down leadership styles are presumed not to be effective (Schneider and Somers, Leadersh Q 17(4):351–365, 2006). Therefore, in this study, a theoretical framework including the necessary leadership attributes within complex adaptive systems will be developed and discussed. The framework presents an integrative perspective of leadership that focuses on effective and necessary leadership attributes, reactions and interactions that are expected to positive organizational performance in complex and chaotic environments. © Springer Science+Business Media Dordrecht 2014

Mathematical models based on thermodynamic, kinetic, heat, and mass transfer analysis are central to this chapter. Microbial growth, death, enzyme inactivation models, and the modeling of material properties, including those pertinent to conduction and convection heating, mass transfer, such as diffusion and convective mass transfer, and thermodynamic properties, such as specific heat, enthalpy, and Gibbs free energy of formation and specific chemical exergy are also needed in this task. The origins, simplifying assumptions, and uses of model equations are discussed in this chapter, together with their benefits. The simplified forms . . . of these models are sometimes referred to as “laws,” such as “the first law of thermodynamics” or “Fick’s second law.” Starting to modeling a study with such “laws” without considering the conditions under which they are valid runs the risk of ending up with erronous conclusions. On the other hand, models started with fundamental concepts and simplified with appropriate considerations may offer explanations for the phenomena which may not be obtained just with measurements or unprocessed experimental data. The discussion presented here is strengthened with case studies and references to the literature. © 2017, Springer International Publishing AG

In this paper we give a short survey of the boundary value problems in polydomains in the last decades. Firstly we develop an alternative method to derive integral representations for functions in C n . This unified method provides representations which are suitable to be employed in discussions for all linear boundary value problems. In the rest of the article we have improved some results obtained for Schwarz and Dirichlet type problems. © Springer Nature Switzerland AG 2019.

This study examines the effect of entrepreneurial activity on economic growth in MENA countries. Following the endogenous growth model, we included human capital and technology spillover variables into the analysis. Due to limited data of entrepreneurship measures in MENA countries this study employed self-employment rate as a proxy. As the level of education increases, absorptive capacity and innovation capacity of the entrepreneurs’ increase. In order to adjust for human capital, the interaction variable of self-employment and average years of schooling are used. The fixed- effect panel regression estimates that the effect of self . . .-employment on economic growth is negative in all specifications. However, the interaction estimate of self-employment and average years of schooling are positive and significant. Our results suggest that the driving force of entrepreneurship in MENA countries is also affected by the economic necessities. On the other hand, the level of education accelerates the effect of entrepreneurial activity on economic growth. © Springer International Publishing AG, part of Springer Nature 2018

For those studying the biomechanical response of the lumbar spine, anatomical meshes obtained from medical imaging data is quite important. However, such models are generally fixed and can only represent a single subject’s geometry. The objective of this study was to improve our previous lumbar vertebral CAD model such that the parameters are now extracted from the CT scan using a semi-automatic procedure. To illustrate the procedure, first, the transverse cross-sections of vertebral bodies were obtained from an individual at three levels, superior, middle and inferior. Parametric contour curves were fitted onto the vertebral body b . . .oundaries using an optimization procedure and the fitting errors are reported here. Five lumbar vertebral bodies were then formed using the lofting operation. Hausdorff distance between the CAD and segmentation models was used to assess the accuracy of the resulting models. The means and standard deviations of Hausdorff distances are also reported here. The adopted optimization process was observed to be resulting coefficient of determination values as high as 0.978. Our new model is expected to lead to dramatic reductions in both time and effort required to build a patient-specific biomechanical model. © Springer Nature Switzerland AG 2019

In this presentation, we will discuss the Neumann problem for higher-order model equations in the unit polydisc of C 2 . We derive the integral representations of the functions defined in the unit polydisc of C 2 which may particularly be suitable for Neumann problems. © Springer Nature Switzerland AG 2019.
