First Order Phase Transition in the 3-dimensional Blume-Capel Model on a Cellular Automaton

The first order phase transition of the three-dimensional Blume Capel are investigated using cooling algorithm which improved from Creutz Cellular Automaton for the $D/J=2.9$ parameter value in the first order phase transition region. The analysis of the data using the finite-size effect and the histogram technique indicate that the magnetic susceptibility maxima and the specific heat maxima increase with the system volume ($L^{d}$) at $$.Comment: 13 pages, 4 figure

Investigation of branch breaking resistances in “Sari Zeybek” fig cultivar

The aim of this study was to examine the branch breaking characteristics of the 4 to 5 years old branches mechanically by a determination of the breaking resistance in Sari Zeybek fig cultivars. In this respect, the study was conducted with 10 different ages for trees belonging to Sarilop cultivar, known with a characteristic of drying and Sari Zeybek cultivar, known with equal or even better characteristics. The sclerenchyma tissues of the 1 to 5 aged branches of Sari Zeybek cultivar were weaker in degree than some other fruit tree species, especially the Sarilop cultivar. Furthermore, it was brought out that the breakages were related to the flexibility of tissues even with the excess forced application (150 kg.) in Sarilop. In Sari Zeybek cultivar, where there is an existence of the branch breakage problem, the length and diameters of branches increased with the increasing branch ages. In particular, the forces at the branch collar were increased due to the fruit weight increase in trees, starting with the 4 to 5 year aged branches. According to the approach of encouragement of branch breakages due to the aforementioned reason, it was taken seriously that shape prunings need to be made more carefully, and not allowed in over critical levels branch lengths and angles within 1 to 4 years growth in Sari Zeybek cultivar.Key words: Sari Zeybek, fig, branch breakage

Reentrant Phase Transitions of the Blume-Emery-Griffiths Model for a Simple Cubic Lattice on the Cellular Automaton

The spin-1 Ising (BEG) model with the nearest-neighbour bilinear and biquadratic interactions and single-ion anisotropy is simulated on a cellular automaton which improved from the Creutz cellular automaton(CCA) for a simple cubic lattice. The simulations have been made for several sets of parameters $K/J$ and $D/J$ in the $-3<D/J\leq 0$ and $-1\leq K/J\leq 0$ parameter regions. The re-entrant and double re-entrant phase transitions of the BEG model are determined from the temperature variations of the thermodynamic quantities ($M$, $Q$ and $\chi$). The phase diagrams characterizing phase transitions are compared with those obtained from other methods.Comment: 12 pages 7 figure

Occupational burnout and cyberloafing among teachers: Analysis of personality traits, individual and occupational status variables as predictors

One of the phenomena that causes remarkable losses in terms of productivity and cost in organizations is occupational burnout. Burnout is encountered in different occupational groups. However, in professions that are in contact with a large number of people as part of their responsibilities, such as teaching, burnout is a problem that is far more on the foreground. In addition, emotional burnout, which is seen as the first step before occupational burnout, can cause workers to feel insufficient at the point of carrying out tasks related to their duties, leading to behaviour that is out of their fields such as cyberloafing. Addressing this situation in terms of teaching profession, the feeling of inadequacy in educational activities during the course may prevent the teacher from fulfilling any responsibilities while using a device that has internet access. In this context, the aim of this study is to investigate the factors that predict the cyberloafing and burnout levels of teachers working in different fields. This research is a relational research. This research was carried out with the participations of 194 teachers from different branches working in various provinces in Turkey. In this study, a personal information form and three different data collection tools were used. Analysis of the collected data was performed by hierarchical linear multiple regression analysis. The 9 models, created separately with cyberloafing and burnout, were found to be significant in the study. Demographic variables, ICT usage status variables, occupational variables and personality traits were used in these models. Therefore, all the hypotheses included in the research were accepted. As a result of the research, demographic variables were found to be the most important model to predict teachers' occupational burnout. The most important model explaining teachers' cyberloafing situations is their ICT usage. (C) 2018 Western Social Science Association. Published by Elsevier Inc. All rights reserved
