Oppdragelsessyn i endring? : En komparativ studie av populære oppdragelsesbøker utgitt i Norge i perioden 1950-2000
2017
Masteroppgave pedagogikk PED511 - Universitetet i Agder 2017 The topic of this assignment is to study if the view of parenting has changed in Norway. There have been many discussions about parenting and what it entails. This study is limited to popular books that have been released in Norway between 1950 and 2000. The parenting books emphasise different aspects in the children’s upbringing and how that positively affects their development. The primary research question is to examine the views of parenting and its development from four books from the selected period: “Barneoppdragelse” by Lise Østlyngen (1950), “Barn og foreldre: barneoppdragelse i praksis” by Hambro & Moa (1966), “Elsker du…
Damping Provision by Different Virtual Synchronous Machine Schemes
2020
The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…
Sensitivity Analysis and Frequency Dynamics of Grid-Connected Converters with Virtual Inertia
2021
For the participation in the frequency control of the system, power converters can be controlled with different strategies and methods, sharing the common concept of virtual inertia capability. In this work, a sensitivity analysis of two main categories of converter controls with virtual inertia is presented. The considered schemes are a grid-following current vector control with additional virtual inertia block and a grid-forming control scheme based on virtual synchronous machine concept. A proper basis for the comparison is first assessed providing an analytical correlation between the control parameters of the two schemes. For the two control strategies, the sensitivity analysis of the …
Passive Control of Linear Structures Equipped with non-Linear Viscous Dampers and Amplification Mechanism
2008
Fluid damper devices in civil structures such as buildings or bridges are commonly used as energy absorbers for seismic protection. The problem in the response analysis of structures with filled dampers mainly consists in the fact that, due to the strongly nonlinear behavior of such equipments, the response spectrum technique fails. Moreover, in order to enhance the damping effect various toggle brace configurations have been recently proposed. In this paper by using the concept of power spectral density function compatible with the elastic response spectrum and the stochastic linearization technique, the equivalent damping ratio is obtained. It is shown that once the system is linearized r…
The marketplace vulnerability of low-income unbanked consumers : a developing country perspective
2018
Financial exclusion is recognised as an important element of socio-economic inequality where economically vulnerable groups are excluded from basic financial services. The issue of financial exclusion is mainly concentrated in the world’s developing countries. However, research on the issue of financial exclusion in the field of marketing as well as from the perspective of unbanked consumers is lacking. Although financial exclusion impedes low-income consumers’ welfare, there is a shortage of wellbeing related studies on low-income consumers in the context of developing countries. This doctoral dissertation aims to investigate the ways in which low-income unbanked consumers experience vulne…
“The Evils Which Have Arisen in My Country” : Mary Power Lalor and Active Female Landlordism during the Land Agitation
2021
The British journalist and author, Frederic Whyte, reminisced fondly about his childhood trips to County Tipperary, presenting an idealistic image of Mary Frances Power Lalor, one of the most active of Irish landowners during the later Victorian period. peerReviewed
Interaction between students and class teachers in vocational education and training: ‘Safety distance is needed’
2020
Interaction between students and teachers is fundamental and has therefore been widely studied in education. However, there have been few studies on intensive spe-cial support being provided to vocational education and training (VET) students. Firstly, the focus of this article is on students’ perceptions of interactions with their class teachers. Students (aged 17–34 years) from four Finnish vocational institutions providing intensive special support were interviewed. According to the findings, the demands students placed on their class teachers and for interactions with them were modest and their perceptions of both were favourable. Interactions seemed to be study-orientated and class tea…
Lastentarhanopettajien huippukokemukset työhyvinvointia rakentamassa
2010
Tutkimus tarkastelee lastentarhanopettajien työhön liittyviä huippukokemuksia. Teoreettisena lähtökohtana toimii Csikszentmihalyin flowkäsite. Ilmiötä lähestytään kolmen tutkimusongelman avulla, joilla selvitetään huippukokemusten ominaisuuksia, työtiimin ja -yhteisön merkitystä niiden ilmenemiseen sekä huippukokemusten yhteyttä työhyvinvointiin. Tutkimuksen tarkoituksena on ollut löytää työhyvinvointiin vaikuttavia tekijöitä ja mahdollisia keinoja hyvinvoinnin lisäämiseksi päiväkotikontekstissa. Lastentarhanopettajien työhön liittyvät huippukokemukset eli työhön uppoutumisen hetket olivat erityisiä kokemuksia ja ne erosivat arkisesta työnilosta. Tilanteisiin sisältyi onnistumisen ja pystyv…
Miten opettaja rakentaa pedagogisen auktoriteetin? Otteita opettajan arjesta
2002
Laadullisen tutkimuksen päätavoitteena oli pureutua siihen, miten opettaja ymmärtää ja rakentaa pedagogisen auktoriteettinsa koulun arjessa. Koska auktoriteettisuhde ei todennu ajatuksissa, puheessa ja kuvitelmissa, tutkin myös, miten auktoriteetti toimii ja saa oikeutuksen luokkatilanteessa. Pedagoginen auktoriteetti liitetään taustakirjallisuudessa toisaalta varsinaisen vallankäytön ulkopuoliseen, kasvatukseen liittyvään auktoriteettisuhteeseen, toisaalta korostetaan henkilösuhteen merkitystä auktoriteettisuhteen muotoutumisessa. Työn peruskysymys on sama kuin työn nimi: Miten opettaja rakentaa pedagogisen auktoriteetin? Osakysymyksiä ovat seuraavat: Mitä ilmiöön pedagoginen auktoriteetti…
