Design Scheme of New Tetragonal Heusler Compounds for Spin-Transfer Torque Applications and its Experimental Realization
2012
Band Jahn-Teller type structural instabilities of cubic Mn(2)YZ Heusler compounds causing tetragonal distortions can be predicted by ab initio band-structure calculations. This allows for identification of new Heusler materials with tunable magnetic and structural properties that can satisfy the demands for spintronic applications, such as in spin-transfer torque-based devices.
Spin caloric transport from density-functional theory
2019
Spin caloric transport refers to the coupling of heat with spin transport. Its applications primarily concern the generation of spin currents and control of magnetisation by temperature gradients for information technology, known by the synonym spin caloritronics. Within the framework of ab initio theory, new tools are being developed to provide an additional understanding of these phenomena in realistic materials, accounting for the complexity of the electronic structure without adjustable parameters. Here, we review this progress, summarising the principles of the density-functional-based approaches in the field and presenting a number of application highlights. Our discussion includes th…
An Examination of Tourist Arrivals Dynamics Using Short-Term Time Series Data: A Space—Time Cluster Approach
2013
The purpose of this study is to examine the development of Italian tourist areas ( circoscrizioni turistiche) through a cluster analysis of short time series. The technique is an adaptation of the functional data analysis approach developed by Abraham et al (2003), which combines spline interpolation with k-means clustering. The findings indicate the presence of two patterns (increasing and stable) averagely characterizing groups of territories. Moreover, tests of spatial contiguity suggest the presence of ‘space–time clusters’; that is, areas in the same ‘time cluster’ are also spatially contiguous. These findings appear to be more robust in particular for those series characterized by an…
Social psychological aspects of ACL injury prevention and rehabilitation: An integrated model for behavioral adherence
2017
Managing rehabilitation for ACL injury is dependent on uptake of, and compliance with, medical and safety recommendations. In this paper, we propose a multi-theory model that integrates self-determination theory and the theory of planned behavior to identify the motivational determinants ACL injury prevention and management behaviors and the processes involved. nonPeerReviewed
Technical, tactical and spatial indicators related to goal scoring in European elite soccer
2020
The aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, o…
Effects of Rule Changes on Game-Related Statistics in Men's Water Polo Matches
2017
The aim of this study was to investigate the effects of rule changes on game-related statistics in men's water polo matches. A total of 856 men's matches played in all Olympic Games and World Championship since 1936 was analysed. The game-related statistics considered were: total goals, winners' goals, losers' goals, goals per minute, goals difference, relationship difference goals and total goals, and relationship difference goals and winners' goals. The rule changes were grouped by structural (game and period) and functional changes (possession time, exclusion time, timing, minimum distance to take a direct shot). Differences between rule changes were determined using a one-way ANOVA. In …
Edukacja zrównoważonego rozwoju wobec wyzwań społeczeństwa XXI wieku
2017
Idea zrównoważonego rozwoju w dobie permanentnego postępu technologicznego i cywilizacyjnego z jednej strony i braku poszanowania środowiska naturalnego z drugiej powoduje, że edukacja młodego pokolenia w XXI wieku ma szczególną rolę do spełnienia. Edukacja na rzecz zrównoważonego rozwoju, aby osiągnęła zamierzony efekt, potrzebuje holistycznego rozumienia środowiska jako układu stosunków ekologicznych, ekonomicznych i społeczno-kulturowych, w otoczeniu których egzystuje młody człowiek-uczeń. W opracowaniu wskazano zadania dla nauczycieli, którzy mają prowadzić świadomą edukację zgodnie z ideą zrównoważonego rozwoju. Dokonano również analizy podstawy programowej obowiązującej w różnych typa…
Mobilità e Urbanistica nella città diffusa
2014
The town that spreads in the territory no longer has “limits”, this urban sprawl produces the use of the land and an inevitable increase in demand for mobility. Since the contemporary town, organized only for those who use their car, does not guarantee those who want to move using public transport so a “slow” mobility could contribute to improving the quality of life in towns. This study reflects on a case study characterized by a continuous urbanization – a widespread town traveled “quickly” - to transform it, with sustainable urban planning and a multidisciplinary approach, in a landscape to cross through the design of different paths for different “speed”, for different types of users.
Zarząd "kadłubowy" w spółce z ograniczoną odpowiedzialnością
2021
Niniejszy artykuł przedstawia zagadnienie zarządu „kadłubowego” w spółce z ograniczoną odpowiedzialnością. Omawiana instytucja prawa handlowego nie została unormowana przez Kodeks spółek handlowych, lecz została wypracowana przez doktrynę. Autor w niniejszym artykule przedstawia typowe aspekty funkcjonowania zarządu – reprezentacja spółki oraz prowadzenie spraw spółki przez zarząd „kadłubowy”. Analizując różne stanowiska wypracowane zarówno przez doktrynę, jak i orzecznictwo sądowe, Autor stara się pokazać, że ważniejszą kwestią od istnienia samego organu dla prawidłowego funkcjonowania spółki niezbędna jest odpowiednia liczebność organu w celu dokonania ważnych czynności prawnych w sferze …
