On the mechanism of imine elimination from Fischer tungsten carbene complexes
2016
(Aminoferrocenyl)(ferrocenyl)carbene(pentacarbonyl)tungsten(0) (CO)5W=C(NHFc)Fc (W(CO)5(E-2)) is synthesized by nucleophilic substitution of the ethoxy group of (CO)5W=C(OEt)Fc (M(CO)5(1Et)) by ferrocenyl amide Fc-NH– (Fc = ferrocenyl). W(CO)5(E-2) thermally and photochemically eliminates bulky E-1,2-diferrocenylimine (E-3) via a formal 1,2-H shift from the N to the carbene C atom. Kinetic and mechanistic studies to the formation of imine E-3 are performed by NMR, IR and UV–vis spectroscopy and liquid injection field desorption ionization (LIFDI) mass spectrometry as well as by trapping experiments for low-coordinate tungsten complexes with triphenylphosphane. W(CO)5(E-2) decays thermally i…
Students' problems in the identification of subspaces in Linear Algebra
2018
International audience; The goal of the study presented in this paper is the investigation of students' problems with exercises concerning central topics of linear algebra courses at university level. We present the results of our analysis of students' work on an exercise about subspaces of . We evaluated the written solutions of the task as well as transcripts based on videos taken of student groups working on the problem. We identified and classified descriptions of vector spaces and subspaces that varied widely and demonstrated highly different skills in working with geometric or formal algebraic objects. We analyzed how far students could progress in a complex reasoning process, and ide…
Constant sign and nodal solutions for parametric anisotropic $(p, 2)$-equations
2021
We consider an anisotropic ▫$(p, 2)$▫-equation, with a parametric and superlinear reaction term.Weshow that for all small values of the parameter the problem has at least five nontrivial smooth solutions, four with constant sign and the fifth nodal (sign-changing). The proofs use tools from critical point theory, truncation and comparison techniques, and critical groups. Spletna objava: 9. 9. 2021. Abstract. Bibliografija: str. 1076.
Capturing situational interest in the past : the salience of children’s experiences in open-air museums
2019
Open-air museums are immersive learning environments disseminating ideas about the lifestyle and material culture of pre-modern times. Considering their significance and prevalence in Northern and Eastern Europe, little is known about how contemporary children perceive these cultural heritage spaces. This study scrutinizes how primary school pupils from Sweden and Belarus encountered visits to Skansen (Sweden) and the Belarusian State Museum of Folk Architecture and Rural Lifestyle (Belarus) and expressed experiences about their visits in drawings and in follow-up interpretations. To record the patterns in children’s experiences, a mixed method was employed, including participant observatio…
Adaptación al Espacio Europeo de Educación Superior de un cuestionario de opinión del alumnado sobre la docencia de su profesorado
2014
El objetivo de este trabajo es presentar el proceso de adaptación al Espacio Europeo de Educación Superior del cuestionario de opinión del alumnado sobre la docencia de su profesorado que se ha seguido en la Universidad del País Vasco. En este proceso se ha adoptado una metodología mixta. Tras efectuar la revisión de los cuestionarios de otras universidades, teniendo en cuenta el marco teórico del nuevo cuestionario, las competencias transversales adoptadas por la Universidad y las tres dimensiones que señala la ANECA, se redactaron una serie de indicadores y posibles ítems susceptibles de conformar el nuevo cuestionario. Este marco teórico, los indicadores e ítems fueron contrastados en di…
Discussions of Fatherhood in Male Batterer Treatment Group
2013
The aim of this study was to examine how men who have perpetrated violence toward their partners and participated in batterer group talked about being a father and how they perceived their own fatherhood. The discussion in the group was analyzed qualitatively by using the methods of content analysis. In traditional fatherhood, they talked about avoidant, passiveness, distant, indifference, and authoritative controlling ways of acting. These men also created an image of themselves as active and caring fathers, thus including empathy and nurture in the concept of fatherhood. This new fatherhood was considered an achieved goal and an objective for the men as being a father. Talking about fath…
Lapsiperheiden hyvinvointi koronapandemian aikana: Osaraportti 2: Noin viisivuotiaiden hoito- ja varhaiskasvatusjärjestelyt
2021
Tämä osaraportti esittelee Jyväskylän yliopiston yhteistyössä Terveyden ja hyvinvoinnin laitoksen (THL) kanssa toteuttaman Varhaiskasvatus ja koronapandemia -hankkeen kyselytutkimuksen perusteella noin viisivuotiaiden lasten hoito- ja varhaiskasvatusjärjestelyitä vuoden 2020 aikana. Hanketta rahoittaa Jyväskylän yliopiston osalta Opetus ja kulttuuriministeriö. THL:n osalta rahoitus perustuu lisämäärärahaan, jonka eduskunta myönsi THL:lle koronaepidemian yhteiskunnallisten vaikutusten tutkimukseen. Kysely ajoittui vuosien 2020–2021 vaihteeseen, ja sen kohderyhmänä olivat 1.10.2014–30.9.2015 välisenä aikana syntyneiden lasten vanhemmat. Kyselyssä tarkasteltiin lasten hoito- ja varhaiskasvatus…
Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…
2021
Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…
Online support for vulnerable consumers: a safe place?
2017
Purpose This paper aims to examine the service experience in an online support community of consumers to understand the nature of social support and how it is experienced and enacted by vulnerable consumers. Design/methodology/approach A netnographic study was conducted to examine vulnerable consumers’ participation in an online support group for weight management. The Linguistic Inquiry Word Count (LIWC) program was used, and additionally data were coded using open coding. A hybrid approach to data analysis was undertaken using inductive and deductive methods. Findings The findings suggest online social support groups can be used as an online “third place” to support vulnerable consumers, …
