Bicommutants of reduced unbounded operator algebras
2009
The unbounded bicommutant $(\mathfrak M_{E'})''$ of the {\em reduction} of an O*-algebra $\MM$ via a given projection $E'$ weakly commuting with $\mathfrak M$ is studied, with the aim of finding conditions under which the reduction of a GW*-algebra is a GW*-algebra itself. The obtained results are applied to the problem of the existence of conditional expectations on O*-algebras.
Mutiskā tulkošana evaņģēliskajās draudzēs ar dievkalpojumiem krievu valodā
2017
Maģistra darbs „Mutiskā tulkošana evaņģēliskajās draudzēs ar dievkalpojumiem krievu valodā” izstrādāts 2017. gada pavasarī. Mutiskās tulkošanas nozares pētniekus arvien vairāk interesē dažādu tulkošanas situāciju pētniecība. Taču mutiskā tulkošana draudzēs, neskatoties uz tās vēsturisko nozīmi tulkošanas jomā, arvien palikusi novārtā. Šī darba autore, draudzes tulks ar 25 gadu stāžu, vēlās pievērst uzmanību šai savas kompetences jomai, mutiskajai tulkošanai evaņģēliskajās draudzēs ar dievkalpojumiem krievu valodā, un izveidot „ideālā” draudzes tulka portretu, balstoties uz klientu vēlmēm. Pētījums tika uzsākts 2015. gadā, veicot pilotaptauju, un turpinājās 2017. gadā. Kopumā 258 respondenti…
Enhancing Joined-Up Government and Outcome-Based Performance Management through System Dynamics Modelling to Deal with Wicked Problems: the Case of S…
2015
The paper by Auping et al. (2015) focuses on the topic of societal ‘ageing’, that is, ‘a population process, caused by declining fertility and mortality rates, which manifests itself in the growing number of older persons in society’ (Huber, 2005). A broader definition frames societal ageing as a ‘demographic, structural, cultural and economic transformation resultant from the increase in the number and proportion of “older” people within society’ (Victor, 2005, p. 5). ‘Double societal ageing’ today characterizes most developed countries, which experience both an increase in the percentage of older people and in their life expectancy. In terms of public policy and finance, the relevance of …
Children's expectancy beliefs and subjective task values through two years of school-based program and associated links to physical education enjoyme…
2016
Purpose: The present study examined the patterns of children's expectancy beliefs and subjective task values through the Physical Activity as Civil Skill Program and associated links to physical education enjoyment and total physical activity. Methods: The sample comprised 401 children aged 9–13 years from 3 small towns located in North-East Finland. All children received school-based activities across 2-year program from Grades 5 to 7. The present data were collected using questionnaires across 3 measurement phases during 2012–2014. Results: The levels of expectancy beliefs and subjective task values indicated to be relatively high and the development was stable through the program, especi…
Self-Efficacy, Satisfaction, and Academic Achievement: The Mediator Role of Students Expectancy-Value Beliefs
2017
Although there is considerable evidence to support the direct effects of self-efficacy beliefs on academic achievement, very few studies have explored the motivational mechanism that mediates the self-efficacy–achievement relationship, and they are necessary to understand how and why self-efficacy affects students’ academic achievement. Based on a socio-cognitive perspective of motivation, this study examines the relationships among academic self-efficacy, students’ expectancy-value beliefs, teaching process satisfaction, and academic achievement. Its main aim is to identify some motivational-underlying processes through which students’ academic self-efficacy affects student achievement and…
Octupolar excitation of ion motion in a Penning trap: A theoretical study
2014
Abstract High-precision Penning-trap mass spectrometry uses the resonant conversion of the magnetron motional mode into the cyclotron motional mode to determine the cyclotron frequency of the ions under investigation. Usually the conversion process is performed by interaction of the ions with external quadrupolar rf-fields. Recently it was found that conversion by means of octupolar rf-fields entails a tremendous increase in mass resolution and is thus of great interest. However, the conversion results depend in an intricate way on the amplitudes and phases of the octupolar rf-field and of the motional modes of the ions. Experimental progress was hampered by the lack of an underlying theory…
School aspirations, cognitive skills and wage expectations of French Undergraduates
2013
en ligne : http://cemapre.iseg.utl.pt/educonf/2e3/files/submissions_to_web/Bonnard%20Claire_%20Giret%20Jean-Francois_Lambert-Le%20Mener%20Marielle.pdf; This paper aims to study the earnings expectations of first-year students at a French university and to compare them with the observed earnings of young people in the labour market for that same year. Our findings highlight the importance of the environment in which students make their choices about education. Expected earnings are proportionally higher when their parents seem to be involved in the careers guidance, even controlling for the effect of parental socio-economic status. The positive opinion of parents about the orientation or the…
Attraversare l’inatteso selvatico urbano. Un’esperienza di cammino con Stalker a Roma est
2021
Italian cities have undergone in the past century a rapid development which has generated abandoned areas within its limits. Many of these places are now uncultivated and rich in spontaneous vegetation. The article reports the relationship between a wild area in eastern Rome, the ex-SNIA-Viscosa Lake, from which the artistic group Stalker has started some walking experiences. During the crossing of the wild spaces that characterize this part of the city, questions emerged related to the link between a community and unpredictable nature, the search for new approaches to conservation and the planning of natural spaces in the city.
Structure of longitudinal chromomagnetic fields in high energy collisions
2014
We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields.
Scheduling independent stochastic tasks under deadline and budget constraints
2018
This article discusses scheduling strategies for the problem of maximizing the expected number of tasks that can be executed on a cloud platform within a given budget and under a deadline constraint. The execution times of tasks follow independent and identically distributed probability laws. The main questions are how many processors to enroll and whether and when to interrupt tasks that have been executing for some time. We provide complexity results and an asymptotically optimal strategy for the problem instance with discrete probability distributions and without deadline. We extend the latter strategy for the general case with continuous distributions and a deadline and we design an ef…
