Relationship between volume and energy of vector fields

2001

Abstract A unified study of energy and volume functionals is presented here by determining the critical points of a functional that extends simultaneously energy and volume and that is defined on the product of the manifold of smooth maps C∞(M,N) times the manifold M of riemannian metrics on M. The restriction of this functional to different submanifolds of the space of vector fields X (M)× M is also considered, and used to study several functionals generalizing volume and energy or total bending of vector fields

Who Controls Who? Embodied Control Within Human–Technology Choreographies

2017

In this article we explore issues of embodied control that relate to current and future technologies in which body movements function as an instrument of control. Instead of just seeing ourselves in control, it is time to consider how these technologies actually control our moving bodies and transform our lived spaces. By shifting the focus from devices to choreographies among devices, we perform a theoretical analysis of the multidimensional aspects that reside within embodied interaction with technology. We suggest that it is beneficial to acknowledge and reformulate the phenomena of embodied control that go beyond the instrumental user-to-device control scheme. Drawing upon the phenomeno…

Significant in life : Core learning outcomes of a social and emotional course in physical education teacher education

2022

The purpose of the study is to explore physical education (PE) students’ social and emotional learning (SEL) and the meaningful learning experiences during the SEL course. In the teaching profession, understanding SEL is important because the guidance of learning and group dynamics is essentially an interactive social process. Further, previous research shows that focusing on socioemotional skills promotes students’ academic achievement. Teachers’ SEL skills can be developed by training. In PE teacher education annually, 60 first-year-students participate in a 20-hours SEL skills course based on Gordon’s interaction model and SEL concepts. The course consists of practising SEL skills such a…

Multimodal Aposematic Signals and Their Emerging Role in Mate Attraction

2018

Chemically defended animals often display conspicuous color patterns that predators learn to associate with their unprofitability and subsequently avoid. Such animals (i.e., aposematic), deter predators by stimulating their visual and chemical sensory channels. Hence, aposematism is considered to be “multimodal.” The evolution of warning signals (and to a lesser degree their accompanying chemical defenses) is fundamentally linked to natural selection by predators. Lately, however, increasing evidence also points to a role of sexual selection shaping warning signal evolution. One of the species in which this has been shown is the wood tiger moth, Arctia plantaginis, which we here put forward…

From ‘no dogs here!’ to ‘beware of the dog!’ : restricting dog signs as a reflection of social norms

2019

Signs in public space reflect ‘normalcy’ in a community. The authors ask what restricting signs tell us about a society? In order to explore the system and variation in the ways dog signs manifest different norms and control, they compare two different data sets: dog signs in a Northern European town, Jyväskylä in Finland, and two Eastern European villages in Romania. They apply a qualitative methodology based on visual communication, geosemiotics and linguistic landscape studies. The focus of the article is on the resources of addressing and the visual semiotics of the image. The investigated communities seem to create a complementary distribution of what they regulate that is also displa…

System wczesnego ostrzegania w zarządzaniu projektami jako narzędzie wspomagania osiągania sukcesu projektu

2020

Celem artykułu jest zaprezentowanie istoty systemów wczesnego ostrzegania w zarządzaniu projektami w kontekście osiągania celów projektów. Potrzeba stosowania narzędzi wczesnego ostrzegania w zarządzaniu projektami ma uzasadnienie przede wszystkim w fakcie, że z reguły (pomijając zdarzenia nadzwyczajne) przedsiębiorstwa wykazują objawy sytuacji kryzysowych w realizacji podejmowanych projektów na długo przedtem zanim dojdzie do niepowodzenia projektu. Wczesne zidentyfikowanie sygnałów zbliżającego się kryzysu powinno być zatem jednym z podstawowych zadań w zarządzaniu projektami. W artykule omówiono rolę systemu wczesnego ostrzegania oraz jego funkcje. Wskazano na zastosowania systemów wczes…

Latvijas Universitātes Pedagoģijas, psiholoģijas un mākslas fakultātes Datordizaina nodaļas Mākslas profesionālā bakalaura studiju programmas 4. Kursa studenta Klāva Lukaševiča (Stud. apl. Nr. Kl10063) diplomdarbā „Tīmekļa vietņu dizaina attīstība un virzieni 21. gadsimta sākumā.” tiek izpētītas ietekmīgākās un raksturīgākās tīmekļa vietņu dizaina tendences laika posmā no 2000. līdz 2015. gadam. Diplomdarbā ir trīs daļas. Teorētiskajā daļā tiek apkopota informācija par tīmekļa vietņu dizaina tendencēm noteiktajā laika posmā. Empīriskajā daļā tiek izpētīts Latvijā populāru tīmekļa vietņu dizains, un tiek analizēta tā aktualitāte. Radošajā daļā tiek izstrādāts dizaina projekts. Šajā daļā ir d…

Le Crowdsourcing : problématisation sensible autour d'une mise en forme du lien communautaire

2014

International audience; Alors que l’utilisation des plateformes sociales (réseaux sociaux, blogs, wikis) est désormais généralisée (du côté des internautes comme des organisations), on observe un investissement et un intérêt croissant pour les plateformes de création collaborative, issues du paradigme de l’open-innovation (H.Chesbrough). On insistera plus exactement sur les dispositifs de crowdsourcing et de co-création en ligne ayant pour point commun la mise en relation de communautés (de professionnels, d’ingénieurs, de designers, d’experts, de fans…) avec les enjeux communicationnels des organisations. La recherche à propos de ces nouveaux espaces de collaboration en ligne a été jusqu’i…

A Comparative Eye Tracking Study of Usability—Towards Sustainable Web Design

2021

Websites are one of the most frequently used communication environments, and creating sustainable web designs should be an objective for all companies. Ensuring high usability is proving to be one of the main contributors to sustainable web design, reducing usage time, eliminating frustration and increasing satisfaction and retention. The present paper studies the usability of different website landing pages, seeking to identify the elements, structures and designs that increase usability. The study analyzed the behavior of 22 participants during their interaction with five different landing pages while they performed three tasks on the webpage and freely viewed each page for one minute. Th…
