Determination of the Relationship Between Leadership Perceptions of Blue Collars and Organizational Outcomes by Using MLQ Analysis

AbstractThe relationship between leadership and organizational outcomes was investigated by some academicians. Since leadership is a phenomenon that keeps numerous characteristics together and that is the basis of shaping organizational structures, its relationship with organizational outcomes is of particular concern both to the academic world and the business world in practice. Within this scope, the relationship between several different leadership models and organizational outcomes was investigated; however, in the researches, leadership perception studies were carried out only for white collar personnel. When it is considered that particularly most of the employees (followers) working in the production sector are blue collar employees, it is thought that investigating the leadership perceptions of blue collars plays an important role in determining the contribution of leadership types to organizational outcomes.In this study, with the information obtained from 296 blue collar employees who work in food and manufacturing industry in Kocaeli and Istanbul, heavily industrialized provinces in our country, by means of multifactor leadership questionnaire (MLQ), the relationship of leadership behaviors with organizational outcomes (efficiency, satisfaction and extra effort) was investigated. When the multifactor leadership scale (MLQ) was applied to the participants, it was seen that the nine components that shows all leadership dimensions stated by Bass were not clearly decomposed from each other. As a result of reliability and internal consistency tests applied to these data, active and passive leadership dimensions were revised. As a result of the analysis conducted considering these data, the relationships of active and passive leadership dimensions with organizational outcomes were investigated and it was found out that organizational outcomes had a positive strong relationship with active leadership dimension

Quality management in the Turkish Higher Education institutions: Preliminary findings

Bu çalışma, 10-12, Aralık 2015 tarihlerinde İstanbul[Türkiye]’da düzenlenen 5. International Conference on Leadership, Technology, Innovation and Business Management (ICLTIBM) Kongresi‘nde bildiri olarak sunulmuştur.There is an extensive literature on antecedents and positive/negative consequences of quality management in manufacturing organizations. However, studies that focus on quality management in higher education institutions are inadequate. In addition, these studies are generally based on developed countries and small samples. This study examines the situation of quality management in higher education institutions of a developing country, Turkey. In addition, it uses a relatively large data set (241 faculties and institutes) for this aim. The findings show that although the Turkish higher education institutions have progressed in their quality efforts in recent years, there is still a long way to go.Yıldız Teknik ÜniversitesiGebze Teknik Üniversitesiİstanbul Teknik Üniversites

Sectoral system of innovation and sources of technological change in machinery industry: An investigation on Turkish machinery industry

Bu çalışma, 10-12 Aralık 2015 tarihlerinde İstanbul[Türkiye]’düzenlenen 5. International Conference on Leadership, Technology, Innovation and Business Management (ICLTIBM) Kongresi‘nde bildiri olarak sunulmuştur.Machinery industry is the main sector in investment product sector. Therefore it has an strategic importance. Turkish machinery industry must have a technology policy to achieve competitiveness on a global level. This study, focus on the sectors which can produce and transfer technology and knowledge. Thus it is based on the basis of the sectoral system of innovation which can produce industry specific technology. In this study according to innovation activities 250 different scale firms data were collected using a questionnaire prepared by the Oslo Manual. Data were analyzed. And the results obtained from the data used for researching the level of technological capabilities of the sectors. Finally the sector's position in new technological developments such as Industry 4.0 was evaluated.Yıldız Teknik ÜniversitesiGebze Teknik Üniversitesiİstanbul Teknik Üniversites

Early time-locked gamma response and gender specificity

Cataloged from PDF version of article.The aim was to investigate whether gender is a causative factor in the gamma status according to which some individuals respond with time-locked, early gamma response, G+, while the others do not show this response, G-. The sample consisted of 42 volunteer participants (between 19 and 37 years of age with at least 9 years of education). There were 22 females and 20 males. Data were collected under the oddball paradigm. Auditory stimulation (10 ms r/f time, 50 ms duration, 65 dB SPL) consisted of target (2000 Hz; p = .20) stimuli that occurred randomly within a series of standard stimuli (1000 Hz; p = .80). Gamma responses were studied in the amplitude frequency characteristics, in the digitally filtered event-related potentials (f-ERPs) and in the distributions which were obtained using the recently developed time-frequency component analysis (TFCA) technique. Participants were classified into G+ and G- groups with a criterion of full agreement between the results of an automated gamma detection technique and expert opinion. The 2 × 2 × 2 ANOVA on f-ERPs and 2 × 2 × 2 multivariate ANOVA on TFCA distributions showed the main effect of gamma status and gender as significant, and the interaction between gamma status and gender as nonsignificant. Accordingly, individual difference in gamma status is a reliable phenomenon, but this does not depend on gender. There are conflicting findings in the literature concerning the effect of gender on ERP components (N100, P300). The present study showed that if the gamma status is not included in research designs, it may produce a confounding effect on ERP parameters. © 2005 Elsevier B.V. All rights reserved

Affinity purification and characterization of polyphenol oxidase from helianthus tuberosus L.

Polyphenol oxidase (PPO) of Jerusalem artichoke (Helianthus Tuberosus L.) tubers was purified using a Sepharose-4B-L-tyrosine-p-amino benzoic acid affinity gel. Both nativeand SDS-gel electrophoresis analyses of the purified PPO gave a single band (ca. 65 kDa based on SDS-PAGE), indicating that it is a monomer. The purified PPO showed activity towards diphenolic and triphenolic substrates but not with the monophenolic substrates, suggesting that it lacks monophenolase activity. The optimum temperature and pH values vary between 20-35oC and 5.0-8.0, respectively, depending on the substrate used; for catechol, the optimum temperature and pH values were found to be 20oC and 7.0, respectively. The purified enzyme was relatively stable at 40oC but unstable at higher temperatures. Furthermore, IC50 values for various inhibitors and inhibition modes were also determined using catechol as a substrate; β-mercaptoethanol showed the strongest inhibition, followed by 2-mercapto benzothiazol, glutathione, L-cysteine and dithioerythritol, respectivel
