Standardisering av WHO-anbefalingen for fysisk aktivitet for barn og unge og konsekvenser for praksis i norske skoler.
2022
I denne artikkelen tar forfatterne opp til diskusjon Verdens helseorganisasjon (WHO) sin anbefaling for barn og unge om 60 minutter fysisk aktivt daglig, og et eksempel på hvordan denne helsebaserte anbefalingen blir innført som tiltak i norske skoler. Ved hjelp av sosiologiske begreper analyserer forfatterne hvordan fenomener, som for eksempel manglende fysisk aktivitet blant barn og unge, blir formulert som et samfunnsmessig problem og knyttes til handlinger og sosiale grupper. Deretter hvordan slike problemer og løsninger trekkes inn i skolen. Artikkelen analyserer hvilke konsekvenser det kan få for undervisningen og for elevene når det helsebaserte konseptet om fysisk aktivitet blir tra…
Behind the scenes of artificial intelligence: a study of micro-work platforms in France
2019
Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…
Diaspora Start-Up Programs and Creative Industries: Evidence from Romania
2021
Romania is one of the main countries of origin for intra-European migration. The national authorities recently implemented the first major program —Diaspora Start-up—to support the business initiatives of Romanian citizens who live abroad and who are interested in opening a business in their home country. This scheme was developed in parallel with a broader program—Romania Start-up Plus—which was designed to support the entrepreneurial initiatives of individuals residing inside the country. These programs have already supported over 8,600 non-agricultural start-ups created in urban areas. This study conducted a comparative analysis of the two programs based on different criteria and explore…
Kinematic and Elastostatic Design Optimisation of the 3-DOF Gantry-Tau Parallel Kinematic Manipulator
2009
Published version of an article in the journal: Modeling Identification and Control. Also available from the publisher:http://dx.doi.org/10.4173/mic.2009.2.1 One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The Gantry-Tau improves this ration further by allowing a change of assembly mode without internal link collisions or collisions between the links and end-effector. The reconfigurable Gantry-Tau kinematic design obtained by multi-objective optimisation according to this paper gives the following features: 3-D workspace/footprint ration is more than 3.19, lowest Cartesian stiffness in the workspa…
Overview and prerequisites of well-functioning Latvian national innovation system
2013
Analysis and understanding of the national innovation system can help policy-makers to identify strategies for improving innovative performance and overall competitiveness of the national economy. Nowadays we know too little about how to identify and measure specific problems in the system (if at all possible), despite several attempts to define them. Until now, little analysis on the Latvian innovation system was made. The paper aims to analyse the Latvian national innovation system and to provide a factors of well-functioning Latvian national innovation system. This research gives a possibility to researchers and policy-makers to investigate the mismatch between policies and problems and …
The landscape of childhood. A study of young adults’ memories in the face of childhood nature
2022
I denne studien undersøker vi hvilke minner som kommer til syne når unge voksne møter barndommens nærnatur igjen, og hvordan kan vi forstå disse minnene. Arbeidet tar utgangspunkt i en kulturell fenomenologisk forståelse. Åtte unge voksne har gått tilbake til sine barndomssteder i skolens nærnatur sammen med en av forskerne. De har gått, klatret og snakket om friluftsliv, lek og lekesteder ute i barndommen. Metoden åpner for å studere komplekse, kroppsliggjorte og stedsspesifikke minner og erfaringer knyttet til konkrete steder, aktiviteter og sosiale relasjoner. Teoretisk bygger studien på fenomenologen Merleau-Pontys beskrivelser av hvordan mennesker bebor verden, Rosas teori om resonans …
Stability of stochastic nonlinear systems with state-dependent switching
2013
In this paper, the problem of stability on stochastic systems with state-dependent switching is investigated. To analyze properties of the switched system by means of Itô’s formula and Dynkin’s formula, it is critical to show switching instants being stopping times. When the given active-region set can be replaced by its interior, the local solution of the switched system is constructed by defining a series of stopping times as switching instants, and the criteria on global existence and stability of solution are presented by Lyapunov approach. For the case where the active-region set can not be replaced by its interior, the switched systems do not necessarily have solutions, thereby quasi-…
Primer estudio experimental sobre los efectos de la digestión en restos esqueléticos de murciélagos (Mammalia: Chiroptera)
2018
Taphonomic studies dealing with small mammals do not usually consider bats. Therefore, the degree to which bat bones are modi? ed by predation and other taphonomic agents are largely unknown. Here we present the results obtained from a set of experiments developed to approach this issue, focusing initially on the e?ect of digestion. For this purpose several bat bones and teeth were exposed to HCl and to two di?erent proteolithic enzymes. The experiments showed that bat bones are altered by acidic and enzymatic attack in a similar way as the bones of other small mammals. However, some patterns were observed in the teeth that had not been previously described in other groups. Thus, both the i…
