Intra‐individual dynamics of lesson‐specific engagement: Lagged and cross‐lagged effects from one lesson to the next
2020
Background Student engagement denotes active participation in academic work through commitment and involvement in learning tasks (Appleton et al., 2006, Journal of School Psychology, 44, 427). This study looks at questions such as whether engagement experiences in one lesson have an effect on the next lesson. In the present study, process‐oriented analyses were conducted to examine lower secondary school students’ engagement experiences and the stability of those experiences from one lesson to the next. Aims (1) To what extent are students’ engagement experiences, in terms of behavioural and cognitive engagement, emotional engagement, and disaffection, stable from one lesson to the next (au…
Water distribution network robust design based on energy surplus index maximization
2015
The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability to be adopted during the design phase, represent also a valuable and effective indicator of the robustness of the network in alternative network scenarios, and can thus be profitably used in condition of future demands uncertainty. The methodology adopted consisted of (I) multi-objective design optimization performed in order to minimize construction costs while maximizing the resilience index; (II) retrospective performance assessment of the alternative solutions of the Pareto front obtained, under demand conditions…
Tra continuo e discreto. Recenti tendenze nella linguistica contemporanea
2002
This paper investigates the relationship between continuum and discretum within recent theoretical approaches in contemporary linguistics, focusing in particular on the interaction with epistemological and methodological aspects common to physical-mathematical theoretical models
Surrogate-assisted multicriteria optimization: Complexities, prospective solutions, and business case
2017
Complexity in solving real-world multicriteria optimization problems often stems from the fact that complex, expensive, and/or time-consuming simulation tools or physical experiments are used to evaluate solutions to a problem. In such settings, it is common to use efficient computational models, often known as surrogates or metamodels, to approximate the outcome (objective or constraint function value) of a simulation or physical experiment. The presence of multiple objective functions poses an additional layer of complexity for surrogate-assisted optimization. For example, complexities may relate to the appropriate selection of metamodels for the individual objective functions, extensive …
Optiseen sensoriteknologiaan pohjautuvan pulssimittarin hyödyntäminen maksimaalisen hapenottokyvyn ja energiankulutuksen arvioinnissa
2015
Ihmisten kiinnostus oman hyvinvoinnin ja terveyden mittaamiseen on viime aikoina lisääntynyt. Erityisesti Suomessa on perustettu uusia innovatiivisia hyvinvointi- ja terveysteknologian alan yrityksiä. PulseOn – yksi näistä startupeista – on kehittänyt optiseen sensoriteknologiaan pohjautuvan rannekkeen, jonka avulla voidaan mitata pulssia analysoimalla veren liikettä suonissa. Rannekkeen kautta kerätty data lähetetään älypuhelimeen, jossa se jalostetaan edelleen käyttäjäpalautteeksi. Tämän tutkimuksen tarkoituksena oli selvittää, miten tarkasti maksimaalista hapenottokykyä (VO2max) ja energiankulutusta voidaan arvioida optisen sensoriteknologian avulla kerätyn pulssi- sekä matkapuhelimella …
Grappling with the Oral Skills: The learning processes of the low-educated adult second language and literacy learner
2013
This paper focuses on the learning processes in L2 literacy classes in the Netherlands, discussing specifically possible influences of the learning processes during the practice of the oral skills. To achieve a better understanding of the students’ spoken language development, classroom processes of six adult L2 literacy classes were observed during a period of eight months and students were pre- and post-assessed. In comparing the classes, notable differences in gain scores in morphosyntactic features as well as aspects of relevance and coherence in discourse surfaced. In order to explain these differences, certain factors were examined in relation to learner characteristics, classro…
Il calice di Giovanni di ser Iacobo ed altre suppellettili toscane del Trecento in Sicilia: novità su artisti e committenti
2012
La preziosa suppellettile liturgica conservata nel tesoro della Cattedrale di Messina è già nota da tempo agli studiosi perché firmata dall'orafo fiorentino Giovanni di ser Iacobo attivo alla corte reale angioina di Napoli. Il saggio, grazie alla corretta lettura della seconda iscrizione apposta sull'opera, individua la committente, la francescana suor Stefania Rufolo, la probabile destinazione originaria per un convento dell'area amalfitana e le ragioni per cui è successivamente giunta a Messina. Con l'occasione, si fa il punto anche su altre opere toscane coeve con smalti traslucidi The precious liturgical ornament preserved in the treasury of Messina Cathedral has long been known to scho…
Theoretical and computational studies of magnetic anisotropy and exchange coupling in molecular systems
2018
The field of molecular magnetism studies the magnetic properties of molecular systems as opposed to conventional metal-based magnets. The high chemical modifiability of the constituting molecules makes such materials highly versatile, and the small size of the building blocks leads to the rise of various quantum mechanical phenomena, such as tunneling and entanglement. These phenomena can then be further utilized in the construction of nanoscale quantum devices. This dissertation describes computational and theoretical studies in the field of molecular magnetism using state-of-the-art quantum chemical methods based on ab initio multireference approaches and broken symmetry density functional t…
Structural Correspondence Between Organizational Theories
2021
AbstractOrganizational research constitutes a differentiated, complex and fragmented field with multiple contradicting and incommensurable theories that make fundamentally different claims about the social and organizational reality. In contrast to natural sciences, the progress in this field can’t be attributed to the principle of truthlikeness where theories compete against each other and only best theories survive and prove they are closer to the truth and thus demonstrate scientific knowledge accumulation. We defend the structural realist view on the nature of organizational theories in order to demonstrate that despite the multiplicity of isolated and competing explanations of organiza…
Structure ofD-ribonic acid-dimethyltin(IV) in coordinating solvents: an experimental and DFT119Sn NMR study
2006
We have investigated a newly synthesized complex of D-ribonic acid with dimethyltin(IV). The structure of the complex in solution has been characterized by means of 1 H, 13 C, and 119 Sn NMR and by DFT calculations. The comparison of experimental and computational results allowed the determination of the stable conformation in solution as well as the detection of a dimerization process. Moreover, evidence is given of active coordination of the metal by the solvent.
