The role of adolescents' temperament in their positive and negative emotions as well as in psychophysiological reactions during achievement situations
2019
Abstract This study examined the role of adolescents' (n = 190) temperament in their emotional reactions in achievement situations. Adolescents rated their temperament (i.e., surgency/extraversion, negative affectivity, effortful control) and completed achievement tasks in Grade 6. They also reported their emotions before and during challenging and non-challenging tasks. In addition, adolescents' autonomic nervous system reactions (i.e., skin conductance levels) were recorded. The results showed that high effortful control was related to higher levels of positive emotions independent of the degree of task difficulty. Low negative affectivity and high effortful control were related to lower …
Sludinājumu jaunumu serviss
2016
Kvalifikācijas darbs “Sludinājumu jaunumu serviss” ir uz tīmekļa tehnoloģijām balstīta sistēma, kas realizēta kā interneta vietne. Katru dienu daudzi cilvēki stundām ilgi meklē sludinājumu portālos sev interesējošu piedāvājumu, un, manuprāt, tā ir ļoti nelietderīga laika izmantošana. Bieži vien sanāk palaist garām iespēju nopirkt vēlamo preci, jo to ir paspējis izdarīt jau kāds cits. Mana izstrādātā sistēma piedāvā risinājumu visām iepriekšminētajām problēmām. Sistēmas lietotājiem ir iespēja izvēlēties sludinājumu meklēšanas kritērijus un saņemt e-pasta paziņojumus ik reizi, kad sludinājumu portālā tiek publicēts viņam interesējošs piedāvājums. Lietotāji var veikt arī citas papildus darbība…
The social mediators: limits and challenges of a system
2011
Following a study aimed at measuring the limits and challenges of the social mediation system, the authors put forward an examination in this article of the mutual expectations of the social mediator and its employer, the urban community. This sociological study is comprehensive: it uses the method of the individual interview and focus group. The analysis of the results is supported by contributions from Boltanski and Thévenot in order to compare the reference “worlds” of both types of actor. It is supplemented by the analysis of notions of “system” (Foucault) and “professionalisation” (Hainaux et al., Bartoli). The authors try to understand the extent to which the actors understand involve…
Self-reported life-space mobility in the first year after ischemic stroke: longitudinal findings from the MOBITEC-Stroke project
2023
Abstract Background Life-space mobility is defined as the size of the area in which a person moves about within a specified period of time. Our study aimed to characterize life-space mobility, identify factors associated with its course, and detect typical trajectories in the first year after ischemic stroke. Methods MOBITEC-Stroke (ISRCTN85999967; 13/08/2020) was a cohort study with assessments performed 3, 6, 9 and 12 months after stroke onset. We applied linear mixed effects models (LMMs) with life-space mobility (Life-Space Assessment; LSA) as outcome and time point, sex, age, pre-stroke mobility limitation, stroke severity (National Institutes of Health Stroke Scale; NIHSS), modified R…
Détermination du taux de salaire réel et analyse néoclassique
1997
L'ambition des Néoclassiques est d'établir une loi scientifique de la répartition qu’ils expliquent essentiellement de deux façons. La première explication est fondée sur la productivité marginale des facteurs déterminée à la production. La seconde est fondée sur l'échange qui détermine la rémunérationdes facteurs ou leur « prix » sur le marché. Or, ces deux déterminations ne sont pas compatibles. La théorie marginaliste écarte d'emblée une grande partie de la réalité économique représentée par les rendements croissants et constants. Elle limite encore son champ en supposant que sur une quantité fixe d’un facteur on peut employer n’importe quelle quantité de facteur variable, hypothèse néce…
On the Stability of the Soft Pendulum With Affine Curvature: Open-Loop, Collocated Closed-Loop, and Switching Control
2022
This letter investigates the stability properties of the soft inverted pendulum with affine curvature - a template model for nonlinear control of underactuated soft robots. We look at how changes in physical parameters affect stability and equilibrium. We give conditions under which zero dynamics corresponding to a collocated choice of the output is (locally or globally) stable or unstable. We leverage these results to design a switching controller that stabilizes a class of nonlinear equilibria of the pendulum, which can drive the system from one equilibrium to another.
Travail du soin, soin du travail
2020
Cet ouvrage s’adresse à l’ensemble des acteurs du travail du soin. Il vise à repenser dans une perspective interdisciplinaire et interprofessionnelle le concept fondamental de travail à l’aune de sa spécificité dans les services de soins.Le travail du soin ne repose pas que sur des compétences certifiées ou des actes techniques. Un regard, un geste, une présence, une écoute… : il tient pour beaucoup à ce qui ne s’inscrit pas dans les tableaux de bord. Ces dernières années, les transformations organisationnelles ont grandement modifié, voire altéré, les conditions dans lesquelles les soins sont apportés. Indicateurs de qualité, mesure de la rentabilité, cotation des actes : tout le travail d…
Early life of fathers affects offspring fitness in a wild rodent
2019
Intergenerational fitness effects on offspring due to the early life of the parent are well studied from the standpoint of the maternal environment, but intergenerational effects owing to the paternal early life environment are often overlooked. Nonetheless, recent laboratory studies in mammals and ecologically relevant studies in invertebrates predict that paternal effects can have a major impact on the offspring's phenotype. These non‐genetic, environment‐dependent paternal effects provide a mechanism for fathers to transmit environmental information to their offspring, and could allow rapid adaptation. We used the bank vole Myodes glareolus, a wild rodent species with no paternal care, t…
La gestione dell’inadempimento contrattuale negli smart contract
2022
Il contributo ha l’obiettivo di prospettare soluzioni giuridiche alla gestione delle sopravvenienze contrattuali negli smart contract, ipotesi che sembra in contrasto con la loro rigida struttura, che dà luogo all’automatica esecuzione degli stessi. Strumentale è anche il confronto con il sistema giuridico tedesco, grazie al quale si avvalora la tesi che gli smart contract non sono una nuova tipologia contrattuale, ma una formazione digitale dello stesso, al quale però vanno applicati sia i principi generali del contratto sia soluzioni giuridiche già esistenti, benchè adattati all’ultima evoluzione tecnologica, sempre più incline alla dematerializzazione del contratto.
I tempi di lavoro e di riposo nel diritto dell'Unione Europea
2017
L’articolo analizza la normativa europea in materia di orario di lavoro (dir. 2003/88/CE) per come interpretata dalla Corte di Giustizia. Più in particolare vengono discusse le nozioni di orario e tempi di lavoro e la regolamentazione di ferie, lavoro notturno, riposi giornalieri e settimanali, e le discipline speciali; specifica attenzione è dedicata alle deroghe che secondo la direttiva possono essere apportate dall’autonomia collettiva ed individuale (“opt-out”) alla disciplina legale, per sottolineare come il diritto dell’Unione abbia determinato una marcata liberalizzazione dei tempi di lavoro. The present work analyses the EU legislative framework on working time (dir. 2003/88/EC) and…
