Decoupled control scheme of grid-connected split-source inverters
2017
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…
Modellazione numerica del comportamento meccanico delle volte catalane
2010
Il presente lavoro riguarda la modellazione numerica del comportamento costitutivo delle cosiddette volte in foglio (le bóvedas tabicadas) che rappresentano una delle tecniche edilizie tradizionali catalane più diffusamente impiegate da alcuni tra i più grandi architetti spagnoli (primo fra tutti Gaudí) alla fine del XIX secolo [1-3]. Tali volte risultano fondamentalmente costituite da strati alternati di spessore in generale pressoché uguale di mattoni e di malta. Questa particolare caratteristica viene studiata in questo lavoro nel quale si vuole confrontare la modellazione del comportamento costitutivo considerando il materiale come ideale omogeneo con quella ottenuta modellando il mater…
Measuring Vulnerability of Asylum Seekers and Refugees in Italy
2019
In recent years, a growing number of forced migrants have travelled to Italy across the Mediterranean Sea. While the number of new arrivals has diminished since 2017, the Italian reception system still struggles to process the high number of applications for international protection. A significant proportion of forced migrants who arrive in Italy end up living in informal settlements, such as occupied buildings, shacks, containers and tented camps. In this study, we assess the vulnerability of asylum seekers and refugees living in informal settlements in Italy, using data from the first nationally representative survey of this population. We compare a count measure of vulnerability with a n…
The relationships between urbanization and bird functional traits across the streetscape
2023
Publisher Copyright: © 2023 The Authors The urbanization process leads to changes in bird communities’ taxonomic and functional compositions. Highly urbanized areas generally exhibit a reduced number of bird species sharing few functional traits. However, most urban bird studies focused on vegetation patches in temperate cities. In this study, we investigate how urban environmental attributes – noise, height of buildings, and urban vegetation characteristics – modulate species occurrences and the distribution of functional traits across the streetscape of a tropical metropolis. We predicted diverse trait-environment relationships, but that highly urbanized contexts (e.g., noisy streets with…
Associations Among Teacher–Child Interactions, Teacher Curriculum Emphases, and Reading Skills in Grade 1
2017
Research Findings: The purpose of the present study was to examine the extent to which the quality of teacher–child interactions and teachers’ self-reported curriculum emphases are related to children’s reading skill development during their 1st school year. To accomplish this, we assessed the reading skills of 1,029 Finnish children (M age = 85.77 months) twice during Grade 1, and the children’s teachers (n = 91) completed questionnaires concerning their literacy-related curriculum emphases. In addition, teacher–child interactions in terms of emotional support, classroom organization, and instructional support were observed in 29 classrooms. The results of multilevel modeling showed that a…
Understanding Different Approaches to ECE Pedagogy through Tensions
2021
Publisher Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland. The concept of pedagogy is the key to understanding pedagogy in early childhood education (ECE) in the Nordic countries, which are known for their high quality of life and education. However, in ECE, there are several different approaches toward pedagogy and it can be said that pedagogy is a multidimensional and dynamic concept. In this paper, the different approaches to pedagogy are defined and reconceptualized through an integrative literature analysis focusing on scientific papers and research reports of the concept. Five approaches to pedagogy were constructed: pedagogy through interaction, pedagogy through s…
Examining Consumers’ Usage Intention of Contactless Payment Systems
2019
Purpose The purpose of this paper is to develop and test a conceptual model that combines the modified Unified Theory of Acceptance and Use of Technology (UTAUT2) with a consumer brand engagement (CBE) model to predict consumers’ usage intentions toward contactless payment systems in a developed country. Design/methodology/approach The authors cooperated with a contactless payment service provider in Finland and reached out to 22,000 customers, resulting in 1,165 usable responses. The collected data were analyzed using structural equation modeling. Findings The study shows that the UTAUT2 and the CBE model together explain approximately 70 percent of the variance in usage intention. Of the…
Predator response to the coloured eyespots and defensive posture of Colombian four‐eyed frogs
2023
Deimatic displays, where sudden changes in prey appearance elicit aversive predator reactions, have been suggested to occur in many taxa. These (often only putative) displays frequently involve different components that may also serve antipredator functions via other mechanisms (e.g., mimicry, warning signalling, body inflation). The Colombian four-eyed frog, Pleurodema brachyops, has been suggested to gain protection against predation through putative deimatic displays where they inflate and elevate the posterior part of their body revealing eye-like colour markings. We exposed stationary artificial frogs to wild predators to test whether the two components (eyespot/colour markings, defens…
Atgriezeniskā saite franču valodas kā svešvalodas mācīšanā klātienē un neklātienē : pētījums par skolotāju pielietotajām praksēm Latvijā
2022
Pētījuma mērķis ir izpētīt franču valodas kā svešvalodas skolotāju izmantotās atgriezeniskās saites prakses klātienes un tālmācības stundās. Šis pētījums sastāv no teorētiskās un empīriskās daļas. Teorētiskajā daļā ir izklāstīti trīs galvenie jēdzieni: vērtēšana, labošana un atgriezeniskā saite, kā arī tiek pētīti divi mācību modeļi – klātienes un attālinātais. Empīriskajā daļā ir sniegts korpusa un metodoloģijas apraksts, kā arī 10 daļēji strukturēto interviju korpusa analīze, kas transkribētas, lai veiktu satura analīzi. Vispārējie secinājumi parāda, ka klātienes stundās izmantotās prakses atšķiras no attālinātajās stundās izmantotajām praksēm formas un korektīvo stratēģiju ziņā.
Izglītības iestāžu direktoru vērtības kā profesionālās kompetences dimensija
2015
Maģistra darbs „Izglītības iestāžu direktoru vērtības kā profesionālās kompetences dimensija” iztirzā direktoru vērtības to profesionālās kompetences kontekstā ar mērķi noskaidrot, kādas vērtības vai to pamatgrupas veido izglītības iestāžu direktoru profesionālo kompetenci. Darba teorētiskajā daļā tiek analizēta zinātniskā literatūra, Latvijas Republikas un starptautiskie tiesību akti, ar kuriem tiek noskaidroti tādi jēdzieni kā „izglītības iestādes direktors”, „kompetence” un „vērtības”. Tiek izpētīta Šaloma H. Švarca (angļ. Shalom H. Schwartz) universālo vērtību modelis ar mērķi adaptēt šī autora vērtību pētīšanas metodoloģiju darba praktiskajā daļā.
