The purpose of this study is to determine relational links via documents and to have an impression about the development of organization theory in Turkey by using bibliometric methods. Studies of various researchers have been considered with a longditutional approach.The papers which had been presented in National Management and Organization Congress within 10 years were examined in terms of most cited theories, authors, research topics and academic journals. The data were also used for social network analyses to examine interactions between universities, research topics and authors.The data were examined under two periods consist of five years. Findings show that there is a variation between two periods and work style have been transferred to newly founded universities or PhD programs in these universities.

Turkish military services field can be conceptualized for embracing two distinct and inconsistent types of institutional logics, namely; mandatory military service logic as the dominant and pragmatic logics as the alternatives. We examine the relationship between the dominant logic which determines legitimate organizational activities and alternative logics which are activated sporadically in the field of Turkish military services. From this standpoint, the circumstances whereby pragmatic logics as alternative institutional logics become effective in the field without devitalizing the dominant logic is explored. Broadly, the results indicate that dominant and alternative logics can support each other in order to preserve field's static condition, rather than interfere with each other so as to induce a permanent transformation.

This paper identifies the researches that have had the greatest impact on the Information Systems (IS) discipline and analyses the changes that have taken place in the intellectual structure of this discipline within the ongoing paradigmatic debates between Europe and North America. The methodology applies citation analysis and social network analysis to the articles published in four European and North American journals with the highest impact factors in the IS field. The findings of the study reveal a significant difference between the research styles and publication patterns of European and North American research traditions.

Freshwater crayfish are one of the most important aquatic organisms that play a pivotal role in the aquatic food chain as well as serving as bioindicators for the aquatic ecosystem health assessment. Hemocytes, the blood cells of crustaceans, can be considered stress and health indicators in crayfish, and are used to evaluate the health response. Therefore, total hemocyte cell numbers (THCs) are useful parameters to show the health of crustaceans and serve as stress indicators to decide the quality of the habitat. Since, catching the fish and the other aquatic organisms, and collecting the data for further assessments are time-consuming and frustrating, today, scientists tend to use swift, more sophisticated, and more reliable methods for modeling the ecosystem stressors based on bioindicators. One tool which has attracted the attention of science communities in the last decades is machine learning algorithms that are reliable and accurate methods to solve classification and regression problems. In this study, a support vector machine is carried out as a machine learning algorithm to classify healthy and unhealthy crayfish based on physiological characteristics. To solve the non-linearity problem of the data by transporting data to high-dimensional space, different kernel functions including polynomial (PK), Pearson VII function-based universal (PUK), and radial basis function (RBF) kernels are used and their effect on the performance of the SVM model was evaluated. Both PK and PUK functions performed well in classifying the crayfish. RBF, however, had an adverse impact on the performance of the model. PUK kernel exhibited an outstanding performance (Accu-racy = 100%) for the classification of the healthy and unhealthy crayfish.
