Corporate Governance and Tunneling: Empirical Evidence From Turkey
(Economics Bulletin, 2018) Akben Selçuk, Elif; Sener, Pınar
This study investigates whether internal governance mechanisms affect tunneling through intercorporate loans for a sample of Turkish listed non-financial firms over the period 2006 to 2014. While the findings reveal a significant and positive relationship between state ownership and tunneling and a significant and negative relationship between foreign ownership and tunneling the relationship between family ownership and tunneling is non-linear. In addition while board size is negatively associated with tunneling independent directors do not prevent the embezzlement of resources. Furthermore the results indicate that while older firms firms with family chairman and higher growth opportunities are more likely to engage in tunneling activities firm size high cash holding leverage and financial distress do not affect tunneling.

Exploring Competitive Intelligence Practices of French Local Public Agricultural Organisations
(Halmstad University, 2014) Bisson, Christophe
Modern agriculture has increased the need for information when making strategic decisions for farmers since they must be more entrepreneurial to survive. This paper investigates the levels of Competitive Intelligence practices in a French Regional Chamber of Agriculture and its four Departmental Chambers of Agriculture to examine the ability of these public organisations to keep fulfilling one of their missions which is to provide the necessary information and knowledge to farmers. Thus this study proposes a behavioural and operational typology of Competitive Intelligence practice. Both types of organisations demonstrate that they are not well adapted to support the entrepreneurial farmers on this issue. The findings of this study and the diagnosis of the Competitive Intelligence practices applied to the typology could be of help to increase their and other public agricultural structures performance levels. Furthermore the platform has the potential to inspire the public sector through subsequent adaptations.
Generalized and Numerical Solution for a Quasilinear Parabolic Equation With Nonlocal Conditions
(Univ Babes-Bolyai, 2015) Kanca, Fatma; Baglan, Irem Sakinc
In this paper we study the one dimensional mixed problem with nonlocal boundary conditions for the quasilinear parabolic equation. We prove an existence uniqueness of the weak generalized solution and also continuous dependence upon the data of the solution are shown by using the generalized Fourier method. We construct an iteration algorithm for the numerical solution of this problem. We analyze computationally convergence of the iteration algorithm as well as on test example.

An Integrated Framework for Examining Innovation Alignment in Organizations
(World Scientific Publ Co Pte Ltd, 2018) Dilan, Ebru; Aydın, Mehmet Nafiz
Innovation has been promoted as a panacea to solve the long-standing problem of how organizations deal with complexities associated with uncertainty and instability in ever changing environments. information systems (IS) research focusing on innovation has adopted several perspectives to reveal a rich context in which the innovation surfaces as a phenomenon. Examination of a rich context may contribute to a better understanding of an extent to which uncertainty and instability can affect or be affected by innovation strategies that require various innovation efforts in an organization. In this regard one of the most critical issues is to ensure that these innovation efforts can achieve a successful outcome via their strategic and structural alignment. In this research we propose an integrated framework that addresses an innovation alignment issue by employing three high-level notions (strategic dimensions structural characteristics strategizing acts). The integrated framework has been used rigorously in two cases for an explorative purpose. Our interpretation of the evidence suggests that strategizing act as a high-level notion has an explanatory power to articulate the associations between strategic dimensions and structural characteristics. Among other findings we have observed that the closed incremental and process-oriented innovation strategy is particularly relevant to the corporate level whereas radical product-oriented and partially open innovation strategy is associated with a more exclusive innovation structure. © 2019 World Scientific Publishing Company.

Productivity Analysis of Black Sea Container Ports by Using Integrated Entropy and Eatwos Methods
(Eskısehır Osmangazı Univ, 2019) Görçün, Ömer Faruk
The Black Sea region is an extremely important region for global trade. Approaches such as short sea shipping and marine highways, which are on the agenda of European Union lead to increase the importance of Black Sea container ports by day by. Thus, performance of seaports of the region will be important factors, which can affect to their development and improvement that will be happened. Because effectivity of seaports may be effected by many factors, it is needed to use the MCDM methodologies can provide a systematic and structural solution way for evaluation. In this study, a hybrid model, which integrated the entropy and EATWOS methods is proposed to make productivity analysis of Black sea container ports. It is expected that obtained results from this study may have a usable characteristic by investors and public authorities in addition to actors, that placed in the logistics processes

Project Management Method Adoption: a Service Industry Case Study
(IGI Global, 2017) Aydın, Mehmet Nafiz; Dilan, Ebru
The purpose of this research is to understand what aspects of brand-named project management method (Project Management Institute - PMI) have been adopted in a service organization and how. The case context examined demonstrates how a weak-matrix organizational structure and agency interpretation along with project management maturity for IT outsourcing projects can affect adoption of a project management method. An interpretative case study is employed for examining the interplays among key notions underlying project management method adoption in IT outsourcing projects. The case study is framed with a research logic constituting the underlying notions of method adoption: the context the agency and the method and its fragments. It is found that the organization realizes 43 out of 47 processes proposed by PMI. It is also observed that the perceived project management maturity level is not aligned with the method fragments adopted. Among other discussion points the present findings contribute to the existing literature by emphasizing the effects of management control on PM method adoption in IT outsourcing. Furthermore this case allows us to argue that product-focused orientation in project management method adoption is evident and has several implications. The adoption and adaptation of processes in different types of projects is on the authors' future research agenda.

Using Random Forest Tree Classification for Evaluating Vertical Cross-Sections in Epoxy Blocks To Get Unbiased Estimates for 3d Mineral Map
(Gazi University, 2021) Camalan, Mahmut; Çavur, Mahmut
Areal mineral maps are constructed from the polished sections of particles that settle to the bottom of epoxy resin. However, heavy minerals can preferentially settle to the bottom, making the polished surface rich in heavy minerals. Therefore, polished sections will become biased estimates of the volumetric (3D) map. The study aims to test whether any vertical cross-section (any section along the settling direction of particles) can be an unbiased estimate of the 3D mineral map of a chromite ore sample. For the purpose of this study, 2D maps of the vertical cross-sections were acquired by using Random Forest classification coupled with image pre- and post-processing tools. Then, 3D mineral maps were converted from 2D maps without assuming stereological errors. The modal mineralogy and particle size distributions predicted from 3D maps were compared with the same features estimated from the particulate sample by XRD and dry sieving analyses, respectively. Any 2D map which yields a modal mineralogy and a size distribution similar to the true analyses was selected as an unbiased estimate of the true 3D map. The results suggest that any vertical cross-section is an unbiased estimate, unlike polished section at which heavier minerals settle preferentially.
Welfare Effects of Coasean Transactions: a Generalized Graphical Approach
(Yerküre Tanıtım ve Yayıncılık Hizmetleri A.Ş., 2011) Ocakcıoğlu, A. Bora
This article is about the graphical description and analysis of the welfare effects of the Coasean1 transactions between the polluters and the pollutees. 2 Professor Coase, in an article entitled The Problem of Social Cost (1960)3 asserted that in the absence of transaction costs, the opposed parties involved in an activity having “harmful effects” on each other may reach within the market an agreement that can lead to an efficient allocation regardless of the initial endowment of the property rights. According to this agreement, when the polluter has the property right (the right to pollute) the pollutee will offer him/her an indemnity to cease or decrease the activity causing the pollution. On the contrary, when the pollutee has the property right (the right not to be polluted) this time the polluter will offer him/her an indemnity to buy the right to pollute. Ronald Coase put the problem as the following: “This paper is concerned with those actions of business firms which have harmful effects on others…The economic analysis of such a situation has usually proceeded in terms of divergence between the private and social product of the factory in which economists have largely followed the treatment of Pigou in The Economics of Welfare.” 4 As we know, Professor Pigou in his book “Economics of Welfare” proposed that the government can correct the distorted market allocation caused by externalities by imposing an appropriate tax on the polluter. This is what today is called the Pigouvian5 tax. The Pigouvian tax is imposed on the polluter as the price of polluting with a view to decrease it (actually this approach is taught even today in modern books of public finance.) But Coase asserts that approaching the problem via Pigouvian taxes is of reciprocal nature: because, Pigouvian taxes designed to eliminate the harm on the pollutee inflict harm on the polluter. As a matter of fact a Pigouvian tax decreases production and consequently part of the producer’s surplus (and also the consumer surplus of the concerning consumers.) According to Coase instead of Pigouvian taxes the conflicting parties may reach an agreement within the market framework in which the party who does not have the property right may offer an indemnity to the other party having it. George Stigler called Coase’s argument as “theorem”6 . After Coase a large number of scholars went over the matter. An immense literature was developed on the subject. Some of the articles were against and some for the Coase’s assertion. Here in this article none of these are discussed and the validity of the Coasean assumptions and propositions are not questioned at all. The original contributions in this article are the following: 1-The generalization of the cases or models within which the polluters and the pollutees can bargain; 2-The microeconomic equilibrium of the concerning parties after the transaction; 3- The welfare change of each side after the transaction. This article takes the Coase’s assertion as valid and uses the tools of the public sector economics and especially of cost-benefit analysis in the description of different possible transaction cases and equilibrium analyses.

Yereraltı Maden İşçilerini Gerçek Zamanlı Takip Etmek İçin Rfıd Teknolojisine Dayalı Özgün Bir Entegrasyon Metodolojisi
(Gazi Universitesi, 2018) Çavur, Mahmut
In recent years many companies want to keep track of their employees sources and working machines due to various reasons like security coordination performance monitoring. The purpose and requirements are the main factors that determine the methodology of tracking. The real-time tracking can be determined with high precision in open areas with the global positioning system (GPS). However previous research and developments for indoor tracking have mostly focused on infrared wireless LAN and ultrasonic. In this study a Radio-Frequency Identification (RFID) protocol and interface are integrated into an open source Information Systems (IS) software. A tight coupling methodology is developed for integration of RFID into an open source software. The use of open source software as a common interface also provides better spatial display and analysis capabilities. The tracking algorithm is completely unique original and it is encoded in the Java programming language. In the algorithm the accuracy of locating the proximity direction of miners and whether the RFID tag is on the right and left of the last point of RFID receiver is determined with 20 m accuracy. The system was tested in an underground salt mine. The developed methodology and system are now being commercialized in Turkey.
