Abstract
For centuries, Turkey has been the nexus of trade and enterprise in Southeastern Europe. Located between the continents of Europe and Asia, Turkey remains the historical portal of the Eastern and Western worlds. Although rooted in an entrepreneurial spirit, the antiquated trade laws in Turkey hindered the sprawling nation’s ability to trade with others. In the late 1980s however, Turkey liberalized its economic legislation, thus enabling the private sector to take the lead in generating growth and employment. This paper examines the evolving Turkish economy through the vehicles of history, the banking system, foreign investments, government apparatuses, and domestic markets and trade policy. Moreover, this paper identifies strategies and market sectors for potential investors. Finally, this paper offers a counterpoint which notes several possible and current economic pitfalls which have and may continue to handicap Turkey in the global marketplace.

Abstract
Researchers in the field of occupational stress and well-being are increasingly interested in the role of emotion regulation in the work context. Emotion regulation has also been widely investigated in the area of lifespan developmental psychology, with findings indicating that the ability to modify one’s emotions represents a domain in which age-related growth is possible. In this chapter, we integrate the literatures on aging, emotion regulation, and occupational stress and well-being. To this end, we review key theories and empirical findings in each of these areas, summarize existing research on age, emotion regulation, and stress and well-being at work, and develop a conceptual model on how aging affects emotion regulation and the stress process in work settings to guide future research. According to the model, age will affect (1) what kinds of affective work events are encountered and how often, (2) the appraisal of and initial emotional response to affective work events (emotion generation), and (3) the management of emotions and coping with affective work events (emotion regulation). The model has implications for researchers and practitioners who want to understand and facilitate successful emotion regulation and stress reduction in the workplace among different age groups.

Abstract
Racism occurs in many ways and varies across countries, evolving and adapting to sociocultural history, as well as contemporary economic, political and technological changes. This chapter discusses the multilevel dimensions of racism and its diverse manifestations across multiracial societies. It examines how different aspects of racism are mediated interpersonally, and embedded in institutions, social structures and processes, that produce and sustain racial inequities in power, resources and lived experiences. Furthermore, this chapter explores the direct and indirect ways racism is expressed in online and offline platforms and details its impacts on various groups based on their intersecting social and cultural identities. Targets of racism are those who primarily bear the adverse effects. However, racism also affects its perpetrators in many ways, including by limiting their social relations and attachments, and by imposing social and economic costs. This chapter thus analyses the many aspects of racism both from targets and perpetrators' perspectives.

Abstract
Purpose
The present study aimed to demonstrate different computational models, data and stability results obtained in a wide number of projects of various aircrafts such as unmanned aerial vehicles (UAVs), general aviation and big passenger flying airliners in blended wing body (BWB) configurations. Many details of modeling and computing are shown for unconventional configurations, namely, for a BWB aircraft and for tailless UAVs.
Design/methodology/approach
Mathematical models for analysis of static and dynamic stability were built and investigated based on equations of motion in the linearized form using the so-called state variable model for a steady-state disturbed, generally asymmetric, flight.
Findings
Flight dynamics models and associated computational procedures appeared to be useful, both in a preliminary design phase and during the final assessment of the configuration at flight tests. It was also found that the difference between thresholds for static and dynamic stability conditions was equal to 9 per cent of mean aerodynamic chord (MAC) in the case of BWB and 3 per cent of MAC in the case of tailless UAVs.
Practical implications
Many useful information about aircraft dynamics can be easily obtained from computational analyses including time to half/double and periods of oscillation, undamped frequencies, damping ratio and many others. Stability analysis of different unconventional configurations will be easier and faster if an access to such configurations is available.
Originality/value
This paper presents a very efficient method of assessment of the designing parameters, especially in an early stage of the design process. In open literature, there are a great number of datasets for classical configurations, but it is hard to find anything for passenger BWB and tailless UAVs. Stability computations are performed based on equations of motion derived in the stability frame of the reference fixed with one-quarter of MAC. It can be considered as an original, not typical but a very practical approach because values of stability and control derivatives do not change even if the centre of gravity is travelling.

Abstract
Purpose
The purpose of this paper is to identify mechanisms and strategies involved in individual and local responses to complex global sustainability issues such as climate change.
Design/methodology/approach
This paper describes an innovative approach to understanding the role of informal leadership and its utility in influencing societal attitudes and practice. The approach builds on theories of diffusion in which learning about new ideas, practices or technologies occurs through interpersonal communication with informal opinion leaders. It draws on findings from studies in other fields of social research, such as community health, development aid, and agriculture, in which the engagement of opinion leaders has been found to speed up the spread of responsive behaviours. The approach also analyses linkages between the concepts of response capacity to climate change and social capital with the strategies of opinion leaders for influencing societal change through informal social networks.
Findings
Research related to social change in response to climate change has focused predominantly on the need for reform at the public policy and institutional level, and at the other extreme, on individual behaviour change. The role of leaders has been cited as an important component of social change in case studies of adaptive management of natural resources, sustainability studies, and in research on social capital.
Originality/value
Development of the approach will contribute to the understanding of social mechanisms and processes involved in community engagement with complex problems and more specifically, response capacity for climate change at the regional level.

Abstract
Purpose
The purpose of this paper is to present a comparison of nonlinear and linear simulations of aircraft dynamics to determine the divergence of the linear solution from the nonlinear solution.
Design/methodology/approach
The general equations of motion of a transport aircraft are presented both in nonlinear and linear form. The nonlinear equations are solved by using the Runge Kutta method. Linear equations are solved numerically by using the Runge Kutta method and they are also solved exactly by using the Laplace transformation method. All of these solutions are obtained by using the body axis system. The results of the simulations are plotted for different control deflections.
Findings
Solution of linear equations by both methods gave the same results as expected. There are important differences in amplitude and frequency of oscillations which are obtained by using nonlinear and linear equations. These differences increase with growing input control deflection. Therefore, it is appropriate to prefer nonlinear approach to obtain more satisfactory results.
Research limitations/implications
Accurate determination of the aerodynamic derivatives is important for the accuracy of the nonlinear solutions.
Originality/value
Many classical approaches use stability axis system for the solution of linear equations. However, in this paper transfer functions of the aircraft are redefined in the body axis system, because stability axes change with angle of attack and some of the stability derivatives need to be re‐evaluated for each angle of attack. Moreover, in addition to classical text book, linear equations are also solved by using the 4th order Runge Kutta medhod.
