Background: The new human coronavirus that leads to COVID-19 has spread rapidly around the world and has a high degree of lethality. In more severe cases, patients remain hospitalized for several days under treatment of the health team. Thus, it is important to develop and use technologies with the aim to strengthen conventional therapy by encouraging movement, physical activity, and improving cardiorespiratory fitness for patients. In this sense, therapies for exposure to virtual reality are promising and have been shown to (...) be an adequate and equivalent alternative to conventional exercise programs.Aim: This is a study protocol with the aim of comparing the conventional physical therapy intervention with the use of a non-immersive VR software during COVID-19 hospitalization.Methods: Fifty patients hospitalized with confirmed diagnosis of COVID-19 will be divided in two groups under physiotherapy treatment using conventional or VR intervention: Group A: participants with COVID-19 will start the first day of the protocol with VR tasks in the morning and then in the second period, in the afternoon, will perform the conventional exercises and Group B: participants with COVID-19 will start the first day with conventional exercises in the morning and in the second period, in the afternoon, will perform activity with VR. All participants will be evaluated with different motor and physiologic scales before and after the treatment to measure improvements.Conclusion: Considering the importance of benefits from physical activity during hospitalization, VR software shows promise as a potential mechanism for improving physical activity. The results of this study may provide new insights into hospital rehabilitation.Trial Registration:ClinicalTrials.gov, identifier: NCT04537858. Registered on 01 September 2020. (shrink)

Outlines the ten ways to achieve happiness, discusses the relationship between health and happinesss, and examines the importance of cultivating human values.

The bias–variance tradeoff is a theoretical concept that suggests machine learning algorithms are susceptible to two kinds of error, with some algorithms tending to suffer from one more than the other. In this letter, we claim that the bias–variance tradeoff is a general concept that can be applied to human cognition as well, and we discuss implications for research in cognitive science. In particular, we show how various strands of research in cognitive science can be interpreted in light of the (...) bias–variance tradeoff, giving insight into individual differences in learning, the nature of cognitive processes, and debates in cognitive science research.

An important part of research is situating one’s work in a body of existing literature, thereby connecting to existing ideas. Despite this, the various kinds of relationships that might exist among academic literature do not appear to have been formally studied. Here I present a graphical representation of academic work in terms of entities and relations, drawing on structure-mapping theory (used in the study of analogies). I then use this representation to present a typology of operations that could relate two (...) pieces of academic work. I illustrate the various types of relationships with examples from medicine, physics, psychology, history and philosophy of science, machine learning, education, and neuroscience. The resulting typology not only gives insights into the relationships that might exist between static publications, but also the rich process whereby an ongoing research project evolves through interactions with the research literature.

Ranchers and pastoralists worldwide manage and depend upon resources from rangelands across Earth’s terrestrial surface. In the Great Plains of North America rangeland ecology has increasingly recognized the importance of managing rangeland vegetation heterogeneity to address conservation and production goals. This paradigm, however, has limited application for ranchers as they manage extensive beef production operations under high levels of social-ecological complexity and uncertainty. We draw on the ethics of care theoretical framework to explore how ranchers choose management actions. We used (...) modified grounded theory analysis of repeated interviews with ranchers to compare rancher decision-making under relatively certain and uncertain conditions and describe a typology of practices used to prioritize and choose management actions that maintain effective stewardship of these often multi-generational ranches. We contrast traditional decision-making frameworks with those described by interviewees when high levels of environmental and market uncertainty or ecological complexity led ranchers toward use of care-based, flexible and relational frameworks for decision-making. Ranchers facing complexity and uncertainty often sought “middle-ground” strategies to balance multiple, conflicting responsibilities in rangeland social-ecological systems. For example, ranchers’ care-based decision-making leads to conservative stocking approaches to “manage for the middle,” e.g. to limit risk under uncertain weather and forage availability conditions. Efforts to promote heterogeneity-based rangeland management for biodiversity conservation through the restoration of patch burn grazing and prairie dog conservation will require increased valuation of ranchers’ care work.

The religious ideology of contemporary communities of Ukraine and the diaspora that belong to different currents of the Ukrainian mother-tongue movement cannot bypass the figure of Volodymyr Shayan. He holds the leading position in the conscious proclamation of a new religion in Ukraine, based on the revived and rethought pre-Christian beliefs of the ancestors of the Ukrainians and in the creation of the first religious organizations in this area. The figure of V. Shayan is ambiguous, but his ideology (...) has a significant influence on the religious movement of both the Diaspora and Ukraine and imposes a certain imprint on all its movements.

The article continues to study the topic of the uprising of the image of the Kyiv philosophical school as a prominent leading Ukrainian participant in the world philosophical process of the Cold War period in the scientific and socio-political thought of the Western block, especially in the USA, Canada and Western Germany, in the second half of the twentieth century. The history of the formation of this image by scholars of the democratic world, mainly from the Ukrainian diaspora, can be (...) conditionally divided into the following stages: 1. Scientific international interaction between the USSR and the Western bloc during the transition of the USSR from Khrushchew's "thaw" to neo-Stalinist "stagnation" (early 1960s – early 1970s); 2. Intensification of the ideological confrontation between the USSR and the Western bloc countries during transition of the USSR from said "stagnation" to Gorbachev's "perestroika" (early1970s – second half of the 1980s). In contrast to the first separate critical assessments by diaspora philosophers P. Fedenko, D. Soloviy and their colleagues of philosophy in the Ukrainian SSR in the 1950s and early 1960s, primarily articles of T. Shevcenko by the director of the Institute of Philosophy of the Academy of Sciences of the Ukrainian SSR D. Ostryanin (1952 – 1962), the image of the Kyiv philosophical school in the 1970s and 1980s was significantly emphasized abroad. The political aspect of this image, dominant in which became, primarily due to its popularization by the Canadian philosopher T. Zakydalsky, the figure of a prisoner of conscience V. Lisovyi, was supplemented in the same and subsequent decades by the scientific aspect. In the memoirs of the Soviet prisoner of conscience and political immigrant L. Plyushch and in the publications of scientists from the US M. H. Teeter and B. Vitvitsky the image of the said school was generally drawn on the basis of their study of the history of the mentioned institute and the directions of its work in the 1940s – 1970s. At the same time, philosophers of the Ukrainian diaspora K. Mytrovych, W. Oleksiuk, W. Shayan and some their colleagues critically assessed the Ukrainian historical and philosophical achievements of this institute in the 1950s and 1980s. (shrink)
