Decoherence without entanglement and quantum Darwinism
2020
It is often assumed that decoherence arises as a result of the entangling interaction between a quantum system and its environment, as a consequence of which the environment effectively measures the system, thus washing away its quantum properties. Moreover, this interaction results in the emergence of a classical objective reality, as described by quantum Darwinism. In this Rapid Communication, we show that the idea that entanglement is needed for decoherence is imprecise. We propose a dynamical mixing mechanism capable of inducing decoherence dynamics on a system without creating any entanglement with its quantum environment. We illustrate this mechanism by introducing a simple and exactl…
The role of health literacy in the association between academic performance and substance use.
2022
Abstract Background To address social inequalities in adolescent substance use and consequent disparities in health, it is important to identify the mechanisms of the association between substance use and academic performance. We study the role of health literacy (HL) in the association between academic performance and weekly smoking, monthly alcohol use and cannabis ever-use among adolescents in Europe. Methods SILNE-R school survey data, which was collected in 2016–17 with paper-and-pencil-method from Hanover (GE), Amersfoort (NL) and Tampere (FI), were used (N = 5088, age 13–19). Health Literacy for School-aged Children instrument was used to assess students’ HL. Logistic regression anal…
The role of career adaptability resources in dual career pathways: A person-oriented longitudinal study across elite sports upper secondary school
2023
Objectives Obtaining education is an important milestone in athletes’ preparation for their professional career after sport. Literature indicates that combining school and sport is not an easy task for many aspiring youth athletes. It has been proposed that career adaptability, which refers to psychosocial resources enabling individuals to solve complex occupational transitions, present and anticipated vocational development tasks, and career related challenges could be a relevant concept for applied work with student-athletes. In this study, we examined whether there are distinct developmental profiles of career adaptability among adolescent athletes across the upper secondary school years…
Moral conflicts in a project course in information systems education
2005
Tero Vartiaisen väitöskirja kuvaa informaatioteknologian ammattilaisiksi opiskelevien ja työelämässä toimivien IT-ammattilaisten yhteistyöprojektissa kohtaamia moraalisia ongelmia. Hän tutki tietojenkäsittelytieteiden yliopisto-opintoihin kuuluvaa projektikurssia, jossa opiskelijaryhmät toteuttavat alan kehityshankkeita yrityksille. Hanke voi kohdistua esimerkiksi tietojärjestelmän tai organisaation tietojenkäsittelyprosessien kehittämiseen. Liike-elämän ja yliopiston välinen yhteistyö on vaativaa kaikille osapuolille. Vartiainen kartoitti asiakkaiden, opiskelijoiden ja yliopisto-ohjaajien kohtaamia moraalisia ongelmia. Hän keräsi tietoa osallistuvalla havainnoinnilla, haastatteluin, päiväk…
Las formas cotidianas de la felicidad y sus mandatos: Pedagogías del pensamiento positivo, trabajo docente y subjetividad en el neoliberalismo contem…
2020
Positive thinking constitutes one of the great traditions that lead to the idea of the subject as an entrepreneur of himself and is perhaps one of the best that has successfully condensed cultural, political, social and pedagogical processes linked to reflection on well-being in this historical time. The teaching work is especially moved by the pregnancy of these perspectives that challenge the pedagogical field and the education workers as ?agents of change, or at least one more school available to give the discussion on well-being and happiness (yours and the students?) is celebrated and encouraged. In this article, I intend to understand what is being built as pedagogical discourses abou…
La proposta educativa dell'oratorio tra dialogo e testimonianza.
2016
L’oratorio continua ad essere un luogo educativo per tutti i giovani, per lo più di età compresa tra i 6 e i 18 anni, delle famiglie che condividono gli ideali della religione cristiano-cattolica. Esso è anche una palestra formativo-professionale per quei volontari che intendono dedicarsi a compiti educativi. L’uso intelligente del tempo libero dagli impegni di studio, in un clima di letizia e fratellanza, caratterizza l’educazione religiosa offerta ai giovani che frequentano l’oratorio. In alcune “periferie” l’oratorio costituisce l’unico luogo di aggregazione giovanile oltre la scuola. La formazione pedagogica e dottrinale degli educatori che lavorano negli oratori deve essere la prima pr…
Nuorten, valtion vai markkinoiden asialla? : nuorisojärjestöjen hybridit toimintalogiikat
2018
Suomalaiselle kolmannelle sektorille on ollut tyypillistä, että toiminta perustuu kansalaisten vapaaehtoiseen toimintaan yhdistysten jäseninä. Viimeaikaisen tutkimuksen mukaan kolmannen sektorin järjestöt näyttävät kuitenkin omaksuvan piirteitä julkiselta ja yksityiseltä sektorilta eli hybridisoituvan. Tässä tutkimuksessa ilmiötä tarkastellaan yhden järjestöryhmän näkökulmasta. Pääkysymykset ovat, miten valtakunnalliset nuorisojärjestöt määrittävät itsensä kolmannen sektorin järjestöinä ja nuorisotyön kentän toimijoina sekä millaiset institutionaaliset logiikat vaikuttavat niiden määrittelyihin itsestään. Tutkimuksen aineistona käytetään valtakunnallisille nuorisojärjestöille tehdyn kyselyn…
Membership negotiation in the first workplace : newcomers' experiences
2020
PurposeThis qualitative study aims to understand young professional newcomers' experiences of communication processes in membership negotiation in their first workplace after graduation.Design/methodology/approachInstead of a one-time interview, the participants were contacted five to ten times during the three to ten months, beginning when they entered the workplace. The data were analyzed using a constant comparative method.FindingsThree communication processes during membership negotiation were identified: developing reciprocity, seeking and perceiving acceptance and becoming an active member. To experience membership, newcomers need to achieve acceptance and engage in reciprocal communi…
Developing a narrative of worth through participation in critical youth program in Wilmington, Delaware
2017
Positive relationships and having a counterspace can help marginalized youth develop a more positive sense of self and their lives as well as encourage them to promote justice in society. Challenging the youth with an employment program can help them create beneficial goals for their lives and work towards the benefit of others. The purpose of this study was to find whether critical youth work can support the youth to develop a critical consciousness and willingness to fight against oppression. The research examined the Streetleaders program in the lives of marginalized youth in the city of Wilmington, Delaware, the US. This qualitative research was built with eight open-ended interviews, c…
Ecology, fisheries and management of wild brown trout populations in boreal inland waters
2010
Eutrophication of aquatic ecosystems is an increasing problem, especially threatening small and shallow freshwater lakes. While the extreme inputs of nutrients (phosphorus and nitrogen) can nowadays be reduced and controlled rather efficiently, additional measures to reverse eutrophication may be needed. These often involve biomanipulation, typically mass removal of cyprinid fish. However, the success of biomanipulations has many times been limited or short lived. The reasons for this are not well known, perhaps because the more subtle impacts of biomanipulation on the ecosystem-wide processes of lakes have not been thoroughly studied. Natural abundance stable isotopes may provide a cost-ef…
