The general concept of mesomechanical constitutive modeling developed by the first author is applied to the description of inelastic mechanical behavior of concrete under very complex loading in three orthogonal directions. Concrete is modeled as an isotropic heterogeneous medium consisting of elastic inclusions that are embedded in a plastically deforming and fracturing matrix. The fracturing process of the matrix results in cumulative damage, in changes of elastic moduli, and in volumetric expansion. It was the confrontation with the complex experimental data presented in this study that led us to a new version of the hypotheses on which our special model for concrete is based. Three kinds of deformation modes in different loading segments are differentiated: elastic‐plastic‐damaging deformation, elastic‐plastic deformation, and only elastic deformation. Criteria for distinguishing between these three kinds of deformation are newly formulated. The results of this isotropic mesoscale model are shown to agree reasonably well with the experimental data received for very complex loading paths.

Year 2004 was influenced by the strike in the National Hockey League. The reason of this strike was the option of adoption of the wage ceiling for the NHL players. The paper stresses the attention to the problem how to account and measure the possibility of the players’ contracts with options in the new model. We are dealing with the following hypothesis: “Is possible to use the experiences of valuation of financial options not only to ROA (Real Options Analysis) but also for valuation of players’ contracts with option?” The modified Black‐Scholes Formula is one of the possible solutions how to measure the value of the option clause.

This study aimed to examine the similarities and differences between the ability to analyze the environment and exploit new knowledge (absorptive capacity) and the skills to generate value from innovation (appropriation). These fields have similar origins and are sometimes confused by practitioners and academics.

A review was conducted based on a full-text analysis of 681 and 431 papers on appropriation and absorptive capacity, respectively, from Scopus, Science Direct and Lens, using methodologies such as text mining, backward citation analysis, modularity clustering and latent Dirichlet allocation analysis.

In business disciplines, the fields are considered different; however, in other disciplines, it was found that some authors defined them quite similarly. The citation analysis results showed that appropriation was more relevant to absorptive capacity, or vice versa. From the dimension perspective, it was found that although appropriation was considered a relevant element for absorptive capacity, the last models did not include it. Finally, it was found that studies on both topics identified the importance of appropriation and absorptive capacity for innovation performance, knowledge management and technology transfer.

This is one of the first studies to examine in-depth the relationship between appropriation and absorptive capacity, bridging a gap in both fields.
