Ethyl Hexanoate Transfer Modeling in Carrageenan Matrices for Determination of Diffusion and Partition Properties.
2007
; Aroma compound properties in food matrices, such as volatility and diffusivity, have to be determined to understand the effect of composition and structure on aroma release and perception. This work illustrates the use of mass transfer modeling to identify diffusion and partition properties of ethyl hexanoate in water and in carrageenan matrices with various degrees of structure. The comparison of results obtained with a diffusive model to those obtained with a convective model highlights the importance of considering the appropriate transfer mechanism. Modeling of the preliminary experimental steps ensures correct estimation of the conditions for the main aroma release step. The obtaine…
I minori tra nuovi e vecchi media
2020
Il contributo presenta il tema generale della sessione coordinata dall'autrice, sottolineando come il rapporto tra infanzia, media ed educazione, sia diventato sempre più attuale. Quasi ogni aspetto della vita dei minori ha una dimensione online, sia attraverso il loro impegno diretto con le TIC sia attraverso la gestione istituzionale di contenuti o servizi che ne influenzano le condizioni di vita. In questo modo diventa sempre più complesso tracciare il confine tra offline e online, ed è per questo che è necessario esaminare in che modo questo ambiente in evoluzione influisca sul benessere e sullo sviluppo dei bambini dei loro diritti. Il dibattito attuale in molte parti del mondo su mino…
Finnish pre-service teachers’ perceptions of their strategic learning skills and collaboration dispositions
2019
To support the development of pupils’ 21st-century skills, teachers themselves must also be competent in these skills and learn them during pre-service teacher education. The aim of this study is to investigate what kind of profiles emerge among Finnish first-year pre-service teachers’ (N = 872) in terms of perceptions of their strategic learning skills and collaboration dispositions and what background variables explain membership of the profiles found. Latent profile analysis showed five student profiles corresponding to perceived strategic learning skills and collaboration dispositions. The most robust factor explaining the membership of the profiles was life satisfaction. Pre-service te…
Challenge of supporting vocational learning: Empowering collaboration in a scripted 3D game – How does teachers’ real-time orchestration make a diffe…
2012
Along with the development of new technologies, orchestrating computer-supported collaborative learning (CSCL) has become a topic of discussion because new learning spaces challenge teacher to support collaborative learning in new ways. However, despite the optimistic notions of teachers’ orchestration in CSCL situations, there are still no systematic research findings on real-time orchestration. This study is one attempt to fill in the knowledge gap on understanding the differences in knowledge construction processes between settings with and without teachers’ real time orchestration in 3D learning games from a socio-cultural perspective. The aims of the study are twofold. The first aim is…
Processing habits and second language learning: Students’ self‐evaluation of their learning
1994
Abstract This article reports a study of students’ second language learning at the upper stage of the comprehensive school. The aim of the study was to analyse students’ conscious second language learning activity and the kinds of language problems the students themselves recognise. 700 students (14–15 year‐olds), representative of the Swedish‐speaking schools in Finland, answered a questionnaire regarding their learning habits and language problems in Finnish. The differences between successful and less successful students were then analysed. The results show that successful and less successful language learners did not differ from each other in processing intensity and general approach to…
Theoretical and pedagogical perspectives on orchestrating creativity and collaborative learning
2011
The role of teacher is increasingly related to designing and arranging collaborative learning situations in which fruitful and creative group work may occur. This thematic review presents recent studies on creativity and collaborative learning from the perspective of the teacher as conductor of learning processes. The precondition for the design and orchestration of these kinds of learning situations is analysing and understanding of creative and collaborative processes and their contextual adaption. Thus, the first section of this review focuses on the theoretical vantage points of creativity and collaborative learning mainly from socio-cultural perspective. Based on this theoretical groun…
The Last Planner System Style of Planning: Its Basis in Learning Theory
2012
The objective of this article is to contribute to creating a better understanding of the Last Planner System (LPS) - which is associated with Lean Construction - in the light of the learning processes at the basis of knowledge development, and of change and innovation. Founded on a theoretical discussion, three research questions are asked, namely: In what ways can the LPS be expected to alter the learning arenas compared to conventional project management in construction; according to learning theory, what are the main challenges associated with implementing the LPS; and, finally, what kind of learning can be linked to an implemented LPS that functions as intended? The implementation of th…
Deliberate or Instinctive? : Proactive and Reactive Coping for Technostress
2019
Employees in organizations face technostress that is, stress from information technology (IT) use. Although technostress is a highly prevalent organizational phenomenon, there is a lack of theory-based understanding on how IT users can cope with it. We theorize and validate a model for deliberate proactive and instinctive reactive coping for technostress. Drawing from theories on coping, our model posits that the reactive coping behaviors of distress venting and distancing from IT can alleviate technostress by diminishing the negative effect of technostress creators on IT-enabled productivity. The proactive coping behaviors of positive reinterpretation and IT control can help IT users by in…
Palliative Care Professionals' Inner Life: Exploring the Relationships Among Awareness, Self-Care, and Compassion Satisfaction and Fatigue, Burnout, …
2015
Context. Professionals working in the landscape of death and dying frequently are exposed to existential issues, psychological challenges, and emotional distress associated with care at the end of life. Identifying factors that help professionals cope with frequent exposure to issues related to mortality could enhance palliative care providers' and patients' quality of life. Objectives. To improve our understanding of the factors associated with professionals' inner life, through the assessment of an adapted version of Kearney and Kearney's awareness model of self-care. The main assumptions of the study were that competence in coping with death and awareness would be positively related to c…
KNOWLEDGE, ATTITUDES AND COVID-19-RELATED BEHAVIOR AMONG INDIVIDUALS AGED 50 AND OLDER IN LATVIA
2021
The coronavirus disease 2019 (COVID-19) was declared a pandemic by the WHO on March 11, 2020, due to its high infection rate, which caused thousands of deaths worldwide and expanding. The evolving outbreak of COVID-19 requires health-protective behavior that can alleviate the severity of an epidemic. Therefore, recognizing the underlying drivers of health-protective behavior against COVID-19 is urgently needed to form policy responses. The purpose of this study was to investigate the individual-level underlying drivers affecting the formation of knowledge, attitudes, and COVID-19-related health-protective behavior among individuals aged 50 and older who are more vulnerable to complications …
