Opis:
The research aimed to determine significant relationships between selected dimensions of professional life and the work of part-time teachers in a sample of respondents in the Republic of Serbia. In testing the model on a sample from the TALIS 2013 (Teaching and Learning International Survey), which consisted of dimensions of professional development (general and specific), barriers to professional development, evaluation and job satisfaction, showed statistically significant relationships between feedback, specific needs of professional development, and less significant links between the general needs of professional development and the barriers to this development with job satisfaction. Quantitative methods were followed to report the results of the cross-sectional study. Partial least square structural equation modelling (PLS-SEM) was utilised to assess the quantitative data. Research with this sample of surveyed teachers has not been done so far.

Opis:
The reliability study is the most important part of the engineering design process, as it is the basis of analysis and assessment of future product performance in exploitation. Since performance cannot be predicted with absolute certainty, the application of reliability theory includes probability theory and unreliability modeling. The proposed approach has been applied to assess the reliability of gear planetary power transmissions. The assessment of system reliability was determined on the basis of the block diagram method, as a function of the reliability of individual components, calculated by statistical analysis. Using the Weibull model, the reliability of the planetary gear was defined on the basis of the probability of failure of the gear teeth and the results were interpreted to assess the reliability of the component and the entire planetary train. For a more precise assessment of reliability and to avoid modeling every failure and mode of occurrence, a competitive risk model was developed. The reliability assessment study was conducted with a “bottom-up” approach. Reliability has been assessed, for instantaneous, estimated and assigned failures rate of planetary train and component.

Opis:
Building professional identities of student teachers at the beginning of their vocational education and professional training provides opportunities to explore diversity of practice and provide external support. In the available literature, there is only a small number of studies that explore the professional identity of pre-service and student teachers. The main problem of this research is to examine self-reported attitudes toward student teachers’ professional identity dimensions. The second aim of the presented study was examining the reliability and concurrent validity of the Student Teachers Professional Identity Scale (Fisherman & Abbot, 1998), which was used for the first time in Serbia. The initial sample of respondents consisted of 158 students from the Faculty of Pedagogical Sciences. Results indicate that university students perceive teaching roles more as a specific job and not as a profession. They are goal-directed towards their job as teachers and perceive their practice as a part of their studies and not as a result of their professional identity development as teachers. The mentioned scale (for one-factor solution with the satisfactory criterion of confirmatory factor analysis) obtained very good reliability (α = .935) and concurrent validity indicators and values. Researching professional identity at early career stages can help educators to emphasize the multidimensionality and complexity of the teaching profession.
