Understanding Action and Adventure Sports Participation—An Ecological Dynamics Perspective
2017
© 2017, The Author(s). Previous research has considered action and adventure sports using a variety of associated terms and definitions which has led to confusing discourse and contradictory research findings. Traditional narratives have typically considered participation exclusively as the pastime of young people with abnormal characteristics or personalities having unhealthy and pathological tendencies to take risks because of the need for thrill, excitement or an adrenaline ‘rush’. Conversely, recent research has linked even the most extreme forms of action and adventure sports to positive physical and psychological health and well-being outcomes. Here, we argue that traditional framewor…
Activity profile, PlayerLoad™ and heart rate response of Gaelic football players : A pilot study
2019
The objectives of this study were to; quantify positional differences in the activity profiles of Gaelic football players and to evaluate decrements in physical performance during a pre-season competition. Global positioning system (GPS) data was recorded from 36 players from 3 teams across 5 games. The relative distance covered in locomotor activities, peak speed, relative PlayerLoad™ (PL.min -1 )and heart rate responses were evaluated between playing positions and across match periods using a mixed model analysis. The mean relative distance of 92.4 ± 23.3 m.min -1 covered,comprised 28.4 ± 10.2 m.min -1 of high intensity running (m.min -1 ≥4.0 m.s -1 ) and 9.9 ± 3.9 m.min -1 of very high i…

International audience; Bankruptcy of enterprises is macroeconomic issue and a phenomenon of a dynamic and competitive market economy. It results in a lot of negative effects not only for the enterprise and its employees but also for other enterprises and institutions, as well as the state and society. The aim of the article is to carry out the analysis of bankruptcy of Latvian and Lithuanian enterprises. No such study has been carried out so far. Article analyses the dynamics of Latvian and Lithuanian enterprise bankruptcy, which manifest themselves in larger waves in certain periods and the factors that influence them. From 1993-when the bankruptcy of enterprises was started to be officia…
The methodology of the statement of comprehensive income and its impact on profitability: the case of Latvia
2018
International audience; The financial statements of a company are used by external users as the main source of information in order to take financially informed decisions. The author of the article has summarized the study on one of the financial statements-a statement of comprehensive income (CI statement) that enables creditors and investors to assess the process of the formation of company's profit and profitability. Purpose: on the basis of the study of the specificity of the preparation of the statement of comprehensive income to analyze and evaluate the influence of CI statement items on the profitability of Latvian companies. In order to achieve the purpose, the author has structured…
Engaging universities in social innovation research for understanding sustainability issues
2017
International audience; The paper presents the analysis of a three-stage research conducted by the authors within a social innovation project in collaboration with international master students of Riga Technical University for determining the factors, which motivate people to be involved in the solution of social problems. The authors not only analyse and use the outcomes of the students’ research but also provide feasibility study of using the potential of study research at the university, for implementing serious research projects. Data collection from Africa, Asia, America and Europe was organised jointly by all the students via web-based survey for creating an original data base for the…
Graphic model for evaluating the competitiveness and eco-efficiency of eco-innovative projects
2019
Eco-innovation describes the creation of novel and competitively priced goods, processes, systems, services, policies, and procedures that satisfy human needs and improve the quality of life while ensuring sustainable development with minimal use of natural resources and minimal release of toxic substances. This article delves into one of the most pressing problems in improving the assessment of eco-innovative projects meant to effect sustainable development. The article also proposes new criteria for evaluating eco-innovation projects. The purpose is to develop and propose a graphic model by which to assess the innovativeness, competitiveness, and eco-efficiency of eco-innovation projects.…

Review of the Hydrogen Evolution Reaction—A Basic Approach
2021
An increasing emphasis on energy storage has resulted in a surge of R&D efforts into producing catalyst materials for the hydrogen evolution reaction (HER) with emphasis on decreasing the usage of platinum group metals (PGMs). Alkaline water electrolysis holds promise for satisfying future energy storage demands, however the intrinsic potential of this technology is impeded by sluggish reaction kinetics. Here, we summarize the latest efforts within alkaline HER electrocatalyst design, where these efforts are divided between three catalyst design strategies inspired by the three prevailing theories describing the pH-dependence of the HER activity. Modifying the electronic structure of a …
Evaluation of anti-androgenic activity of di-(2-ethylhexyl)phthalate
2005
International audience; DEHP is a widely used platiciser in the manufacture of PVC-based materials. It is known to disrupt the reproductive tract development in male rats. We have performed the Hershberger assay with DEHP on an immature castrated rat model to check if DEHP antagonise the testosterone propionate androgenic effect on the accessory sex organs development. DEHP significantly decreased the BC/LA muscles, the prostate, and the seminal vesicles relative weights from 100, 200, and 400 mg/kg bw/day, respectively. DEHP increased the liver relative weight from 100 mg/kg bw/day. A study was also performed on MDA-MB453 cell line stably transfected with pMMTVneo-Luc with DEHP and its maj…
