The University

This paper presents appreciative inquiry (AI) methodology in the context of management education. Therefore, we propose that AI, which focuses on positive aspects of doing business, needs to be implemented into management education of future managers in Slovenia and Croatia and we provide empirical evidence of thinking patterns of business students studying at the University of Ljubljana and the University of Split. For comparison, we investigated the previous experiences and future expectations of business students in Croatia and Slovenia. Empirical part is composed of two parts: qualitatively based AI and a quantitative study, based on statistical methods. Results show a positive outlook of business students in both countries.

Investment Allocation

Changes in global economic environment meant that companies, particularly publicly traded, seek adaptations to global market model, which gives preference to the analysis of stock indicators profitability. In this sense, we carried out a quantitative study, based on data published by Petrobras SA, concerning the balance sheet comprising the period 2009 to 2013. Data analysis was carried out through statistical methods of covariance, correlation and linear regression. Among the findings of the paper, we emphasize that more than prove the good relations between the good historical results, the joint techniques of statistical methods serve as warnings to indicate to managers that something is not going as expected, thus helping the decision to promote a change in internal company policies, specifically in the way of investment allocation.

Systematic And Random Errors

This review paper deals with the use of statistical methods to evaluate systematic and random errors associated with trigonometric parallaxes. First, systematic errors which arise when using trigonometric parallaxes to calibrate luminosity systems are discussed. Next, determination of the external errors of parallax measurement are reviewed. Observatory corrections are discussed. Schilt’s point, that as the causes of these systematic differences between observatories are not known the computed corrections can not be applied appropriately, is emphasized. However, modern parallax work is sufficiently accurate that it is necessary to determine observatory corrections if full use is to be made of the potential precision of the data. To this end, it is suggested that a prior experimental design is required. Past experience has shown that accidental overlap of observing programs will not suffice to determine observatory corrections which are meaningful.

Ferroelectric Domains

Recent progress in the electron-mirror microscopy (EMM), e.g., an improvement of its resolving power together with an increase of the magnification makes it useful for investigating the ferroelectric domain physics. English has recently observed the domain texture in the surface layer of BaTiO3. The present authors ) have developed a theory by which one can evaluate small one-dimensional electric fields and/or topographic step heights in the crystal surfaces from their EMM pictures. This theory was applied to a quantitative study of the surface pattern of BaTiO3).
