Školski uzrast kao prediktor kvaliteta grupnog donošenja odluka učenika - perspektiva nastavnika

The forms of organization supporting social interaction are favored in the pedagogical and didactical models of work of educational institutions of progressive orientation. Interaction between students during work in small groups is viewed as a significant factor in enabling them for a quality decision-making in the process of interactive work. The paper investigates whether, from teachers' perspective, the age of students is a significant predictor of the quality of decision-making during work in small groups. The attitudes of 162 teachers towards the quality of decisions that students make while working in small groups were examined by using the KDO-MG scale. The assumption that there is a tendency for the quality of decision-making to increase with the progression of students' age was verified by using a single linear regression analysis. The results confirmed that, according to teachers, the age of students can be considered a predictor of the quality of decision-making during work in small groups. It is a relatively weak, but stable prediction. Teachers do not question the positive effect of students' work in small groups, but they believe that it is slightly determined by their age, so that the older the students are, the higher the quality of decision-making during work in small groups.

Exploring the Enablers of Strategic Orientation for Technology-Driven Business Innovation Ecosystems

The present study explores the impacts of corporate strategic orientation on innovation ecosystems through the perspective of systems thinking. Multiple-cases method was adopted to analyze three representative companies of different industries. In terms of academic contribution, the results of this study verify an innovation ecosystem model in a generalized manner, and find that market orientation, interaction orientation, and entrepreneurial orientation generate a positively reinforcing effect on the paths of the innovation ecosystem model in all phases, thus, diversifying the available literature of innovative ecosystems. In terms of practical contribution, this study presents a dynamic context of the development of new business, and describes the links between innovative activities and the market. Enterprises can refer to the proposed framework as well as strategic architecture in this study to effectively transform innovative activities into market performance.

Entrepreneurial Orientation, Interaction Orientation, and Innovation Performance: A Model of Moderated Mediation

This research explored the relationships between entrepreneurial orientation (EO), interaction orientation (IO), and innovation performance based on resource-based theory. We used two market approaches (market-driving and market-driven) to test our research model. We collected data from the responses of 209 corporations in China. Our findings indicated that both EO and IO positively affected knowledge combination capability (KCC), which contributed to innovation performance. The results indicated that organizational collectivism moderated the link between EO and KCC. It also moderated the mediation effect of EO on firm’s innovation performance by KCC. Interestingly, we found that organizational collectivism moderated the link between IO and KCC and also moderated the mediation of IO on innovation performance by KCC. Our research contributes to the field of strategic orientation and suggests that managers should pay attention to the two market approaches and organizational culture, which can improve innovation performance. Furthermore, this research offers theoretical and practical implications to firm’s innovation capability.

Discontinuous Galerkin methods for a kinetic model of self-organized dynamics

This paper deals with the numerical resolution of kinetic models for systems of self-propelled particles subject to alignment interaction and attraction–repulsion. We focus on the kinetic model considered in [P. Degond and S. Motsch, Continuum limit of self-driven particles with orientation interaction, Math. Models Methods Appl. Sci. 18 (2008) 1193–1215; P. Degond, J.-G. Liu, S. Motsch and V. Panferov, Hydrodynamic models of self-organized dynamics: Derivation and existence theory, Methods Appl. Anal. 20 (2013) 89–114] where alignment is taken into account in addition to an attraction–repulsion interaction potential. We apply a discontinuous Galerkin method for the free transport and non-local drift velocity together with a spectral method for the velocity variable. Then, we analyze consistency and stability of the semi-discrete scheme. We propose several numerical experiments which provide a solid validation of the method and illustrate its underlying concepts.

Orientation, interaction and laser assisted self-assembly of organic single-crystal micro-sheets in a nematic liquid crystal

In this paper we report first experimental study on the orientation, interaction and directed-assembly of single crystal micro-sheets in nematic liquid crystals.

CONTINUUM LIMIT OF SELF-DRIVEN PARTICLES WITH ORIENTATION INTERACTION

The discrete Couzin–Vicsek algorithm (CVA), which describes the interactions of individuals among animal societies such as fish schools is considered. In this paper, a kinetic (mean-field) version of the CVA model is proposed and its formal macroscopic limit is provided. The final macroscopic model involves a conservation equation for the density of the individuals and a non-conservative equation for the director of the mean velocity and is proved to be hyperbolic. The derivation is based on the introduction of a non-conventional concept of a collisional invariant of a collision operator.
