    Opis:
    This paper develops a static model of endogenous task-based technical progress to study how factor scarcity induces technological progress and changes in factor prices. The equilibrium technology is multi-dimensional and not strongly factorsaving in the sense of Acemoglu (2010). Nevertheless, labour scarcity induces labour productivity growth. There is a  weak but no strong absolute equilibrium bias. This model provides a plausible interpretation of the famous contention of Hicks (1932) about the role of factor prices and factor endowments for induced innovations. It may serve as a microfoundation for canonical macro-economic models. Moreover, it accommodates features like endogenous factor supplies and a binding minimum wage.

    Opis:
    We analyze the medium- and long-run effects caused by an inflow of capital into a labor-abundant country. For that purpose, we incorporate directed technical change into a Heckscher-Ohlin model with a continuum of goods. This provides a comprehensive theory explaining the dynamics of comparative advantage based on differences in effective factor endowments, i.e. factor endowments adjusted by differences in technological levels. Our model constitutes an appropriate framework for understanding, e.g., the empirically observed changes in industrial structures of Central and Eastern European countries. Furthermore, we provide a theoretical foundation for the empirical Prospective Comparative Advantage index with new insights into the future dynamics of comparative advantage. Eventually, we show the importance of research spillovers and state dependence on the process of convergence.

    Opis:
    In contrast to the abundance of motor skill acquisition and performance research, there is a paucity of work which addresses how athletes with an already learnt and well-established skill may go about making a subtle change, or refinement, to that skill. Accordingly, the purpose of this review paper is to provide a comprehensive overview of current understanding pertaining to such practice. Specifically, this review addresses deliberately initiated refinements to closed and self-paced skills (e.g., javelin throwing, golf swing and horizontal jumps). In doing so, focus is directed to three fundamental considerations within applied coaching practice and future research endeavours; the intended outcomes, process and evaluative measures of skill refinement. Conclusions suggest that skill refinement is not the same as skill acquisition or performing already learnt skills with high-levels of automaticity. Due to the complexity of challenge faced, refinements are best addressed as an interdisciplinary solution, with objective measures informing coach decision making.

    Opis:
    Context: The Technical Debt metaphor has grown in popularity. More software is being created and has to be maintained. Agile methodologies, in particular Scrum, are widely used by development teams around the world. Estimation is an often practised step in sprint planning. The subject matter of this paper is the impact technical debt has on estimations. Objective: The goal of this research is to identify estimation problems and their solutions due to previously introduced technical debt in software projects. Method: The Systematic mapping study (SMS) method was applied in the research. Papers were selected from the popular digital databases (IEEE, ACM, Scopus, etc.) using defined search criteria. Afterwards, a snowballing procedure was performed and the final publication set was filtered using inclusion/exclusion criteria. Results: 42 studies were selected and evaluated. Five categories of problems and seven proposed solutions to the problems have been extracted from the papers. Problems include items related to business perspective (delivery pressure or lack of technical debt understanding by business decision-makers) and technical perspective (difficulties in forecasting architectural technical debt impact or limits of source code analysis). Solutions were categorized in: more sophisticated decision-making tools for business managers, better tools for estimation support and technical debt management tools on an architectural-level, portfolio approach to technical debt, code audit and technical debt reduction routine conducted every sprint. Conclusion: The results of this mapping study can help taking the appropriate approach in technical debt mitigation in organizations. However, the outcome of the conducted research shows that the problem of measuring technical debt impact on estimations has not yet been solved. We propose several directions for further investigation. In particular, we would focus on more sophisticated decision-making tools.

    Opis:
    The current discussion about innovations relates to wider aspects than technological progress or new knowledge. Despite the proved importance of ethics, this aspect is often underestimated with respect to thesuccess of innovation changes. We would like to point out thepossibilities and importance of the implementation of ethical approaches and practices that caninfluence quality, dynamics and successfulness of innovative changes significantly.
    Obecna dyskusja na temat innowacji odnosi się do szerszych aspektów niż postęp techniczny lub nowa wiedza. Mimo udowodnionego znaczenia etyki, ten aspekt jest często niedoceniany w odniesieniu do sukcesu zmian innowacyjnych. Autorzy chcieli zwrócić uwagę na możliwości i znaczenie wdrażania rozwiązań etycznych i praktyk, które mogą mieć duży wpływ na jakość, dynamikę i pełnię sukcesu innowacyjnych zmian.

    Opis:
    Research background: Agriculture plays a vital role in producing food to ensure food security, but it is one of the biggest contributors to environmental pollution. One of the main goals of the new CAP is to set higher ambitions for environmental actions, which brings into the front the concept of agricultural eco-efficiency. The notion of eco-efficiency includes the economic and also ecological dimensions of sustainable agriculture. Purpose of the article: The main goal of this paper is to evaluate the eco-efficiency of agricultural production and its dynamics during the years 2013, 2015, and 2017 of NUTS 2 regions within the Visegrad 4  (V4), i. e. The Czech Republic, Slovakia, Hungary, and Poland. The part of the main goal is to verify the research hypothesis that all the biggest agriculture producers are eco-efficient. Methods: V4 regional eco-efficiency of the agricultural sector is expressed by the Malmquist productivity index and is estimated using the output-oriented Data envelopment analysis (DEA) model, under the assumption of constant return to scale (CRS). The Malmquist index is decomposed to technical eco-efficiency change (EC) and technological change (TC). Based on the eco-efficiency, technological and pure technical eco-efficiency change, V4 regions are classified into three groups: the most progressive regions, the progressive regions, and the regressive regions. Findings & value added: CZ02: Central Bohemia, CZ04: Northwest, HU33: Dél-Alföld, HU31: Észak-Magyarország, HU32: Észak-Alföld, PL21: Malopolskie, PL41: Wielkopolskie, SK01: Bratislava region, and SK02: Western Slovakia have an eco-effective agricultural sector, the remaining V4 regions have eco-ineffective agricultural sector. The research hypothesis that all the biggest agricultural producers are eco-effective is not confirmed. During the analyzed years, 19 V4 regions improve their agricultural eco-efficiency. The main contributor to eco-efficiency improvement is technological progress, which indicates that producers implement innovations that lead to more eco-efficiency agricultural production.
