The use of integrals in Mechanics of Materials textbooks for engineering students: the case of the first moment of an area
2018
International audience; Research has reported on the difficulties engineering students face in relating the content of their mathematics courses to what is taught in their professional courses. One way to address these difficulties is by better understanding how mathematical notions are used in professional engineering courses. This paper analyses how the notion of first moment of an area – which is defined as an integral – is used in civil engineering courses. Basing our analysis on elements from the anthropological theory of the didactic, we are currently analysing a classic Mechanics of Materials book. Our findings indicate that although first moments are introduced as an integral, the t…

Multiparameter quantum critical metrology
2022
Single parameter estimation is known to benefit from extreme sensitivity to parameter changes in quantum critical systems. However, the simultaneous estimation of multiple parameters is generally limited due to the incompatibility arising from the quantum nature of the underlying system. A key question is whether quantum criticality may also play a positive role in reducing the incompatibility in the simultaneous estimation of multiple parameters. We argue that this is generally the case and verify this prediction in paradigmatic quantum many-body systems close to first and second order phase transitions. The antiferromagnetic and ferromagnetic 1-D Ising chain with both transverse and longi…
Tema starosti v romane Gajto Gazdanova "Nočnye dorogi"
2016
Do tematu starości niejednokrotnie zwracał się w swojej twórczości przedstawiciel młodszego pokolenia pierwszej fali emigracji rosyjskiej, Gajto Gazdanow, najczęściej rozpatrując starość w kontekście sensu życia i śmierci. Ważna w tym zakresie jest powieść Nocne drogi, w której temat starości i stosunek do niej zostały zrealizowane głównie w historii właścicielki kawiarni, historii prostytutki Raldi, staruszka-kierowcy itd. Wszyscy bohaterowie mają cechy indywidualne, precyzyjnie uchwycone i wyrażone przez narratora. Temat starości dla Gazdanowa to przede wszystkim możliwość rozważania o sensie życia i śmierci, pokazania kontrastu pomiędzy ograniczonością, bezsensem istnienia i przeżywaniem…
On an idea of Bakhtin and Czerwik for solving a first-order periodic problem
2017
We study the existence of solutions to a first-order periodic problem involving ordinary differential equations, by using the quasimetric structure suggested by Bakhtin and Czerwik. The presented approach involves technical conditions and fixed point iterative schemes to yield new theoretical results guaranteeing the existence of at least one solution.
La gestión en educación física. Dos modelos de gestión, el mismo individuo
2020
In the development of this writing, we intend to critically analyze the idea of management in Physical Education and problematize it with the issues of inclusion and inequality. To do this, first there is a brief etymological review of the concept of management, and then we analyze how Physical Education links management to economic and business Sciences. The analysis material used are books, manuals and articles on Physical Education management. From the analysis of this material, the second point of the work arises to explain two management models in Physical Education that we call: individual management and self-management. These models are presented as different and opposite, but in the…

Examining the Indirect Effect of Online Gaming on Depression via Sleep Inequality and Anxiety—A Serial and Parallel Mediation Analysis
2022
Stress-related disorders are highly prevalent among first-year college students. Gaming disorder (GD) is an emerging disorder linked to physical and psychological consequences. We aimed to investigate the mechanism linking GD with anxiety, depression, and sleep disorders among first-year undergraduate students. Four hundred fifty-seven participants were recruited, and the survey included the Internet Gaming Disorder Scale Short-Form (IGDS9-SF), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Pittsburgh Sleep Quality Index (PSQI). Our results showed that female students scored significantly higher than males in anxiety and depression. Furthermore, we found…
