Strategies for Improving Optimal Positioning of Quality Sensors in Urban Drainage Systems for Non-Conservative Contaminants
2021
In the urban drainage sector, the problem of polluting discharges in sewers may act on the proper functioning of the sewer system, on the wastewater treatment plant reliability and on the receiving water body preservation. Therefore, the implementation of a chemical monitoring network is necessary to promptly detect and contain the event of contamination. Sensor location is usually an optimization exercise that is based on probabilistic or black-box methods and their efficiency is usually dependent on the initial assumption made on possible eligibility of nodes to become a monitoring point. It is a common practice to establish an initial non-informative assumption by considering all network…
Development of Composites with a Self-Healing Function
2015
This research aimed to realize experimentally the facilevascular self-healing system in epoxy glass fibre reinforced composite. Using flexiblepolytetrafluoroethylene tubes as removable preforms, the channels were embeddedinto both neat epoxy resin and unidirectional glass-fibre reinforced epoxy laminate.Room temperature curable epoxy resin with a surfactant and an amine-basedhardener were the components of the binary healing agent. The specimens oftapered double cantilever beam geometry were subjected to Mode I fracture tests.Fracture of specimens released the healing agent from channels and triggeredself-healing process of the crack. Tested neat epoxy resin specimensdemonstrated recovery o…
Investigating occupational well-being and leadership from a person-centred longitudinal approach: congruence of well-being and perceived leadership
2015
The overall objective of this longitudinal study was to investigate the association between perceived leadership and employee well-being from a person-centred approach utilizing the principles of the conservation of resources theory (Hobfoll, S. E. (1989). Conservation of resources: A new attempt at conceptualizing stress. American Psychologist, 44, 513–524; Hobfoll, S. E. (2002). Social and psychological resources and adaptation. Review of General Psychology, 6, 307–324). First, we aimed to identify latent classes (i.e., subgroups) of employees that demonstrated similar mean levels of stability and change in occupational well-being (i.e., vigour and emotional exhaustion) across a mean time…
Antecedents of daily team job crafting
2017
This study investigated potential antecedents of team job crafting defined as the extent to which team members engage together in increasing (social and structural) job resources and challenges, and decreasing hindering job demands. Mindful of the teamwork literature, we hypothesized that individual employee factors (self-efficacy for teamwork, daily affect), team features (team cohesion, climate) and the organizational context of teams (engaging leadership and organizational resources for teamwork) relate positively to daily team job crafting behaviour. Data were collected among 46 multi-professional rehabilitation teams whose members completed two daily surveys after their weekly meetings…
Leaders’ intensified job demands : Their multi-level associations with leader-follower relationships and follower well-being
2022
To study the ever-increasing pace of work practices, we investigated leader experiences of intensified job demands (IJDs) and their effects on followers. Based on the challenge-hindrance approach, different kinds of job demands may produce either negative or positive work-related outcomes. Using this perspective, we investigated the leaders IJDs against their followers’ satisfaction with them as leaders, follower evaluations of the leader-member exchange (LMX) relationship quality, and their personal well-being (burnout and work engagement). Of the four IJDs, (1) work intensification and (2) career-related planning demands were conceptualised as negative hindrances for leaders, whereas (3) …
Deductive and inductive approaches in teaching singular and plural nouns in English
2008
Deduktiivinen ja induktiivinen lähestymistapa ovat jo pitkään kilpailleet keskenään asemastaan kielen opetuksessa. Useista tutkimuksista huolimatta kummankaan lähestymistavan paremmuutta ei ole pystytty osoittamaan. Deduktiivinen lähestymistapa seuraa perinteisempiä opetusmetodeja, joissa säännöt ja esimerkit annetaan ensin, ja tämän jälkeen oppilaat soveltavat oppimaansa useissa tehtävissä. Induktiivinen lähestymistapa puolestaan lähestyy opetettavaa asiaa päinvastaiselta kannalta, jossa oppilaat itse päättelevät säännöt useista esimerkeistä. Säännöt voidaan tämän jälkeen käydä yhdessä läpi. Tämän tutkimuksen tarkoituksena oli vertailla deduktiivisen ja induktiivisen lähestymistavan paremm…
Individuālās pieejas nodrošināšana bērniem ar mācīšanās traucējumiem vispārējās izglītības iestādē 3. un 4. klasē
2017
Diplomdarba „Individuālās pieejas nodrošināšana bērniem ar mācīšanās traucējumiem vispārējās izglītības iestādē 3.un 4. klasē” mērķis ir izpētīt un analizēt individuālās pieejas veidus bērniem ar mācīšanās traucējumiem vispārējās izglītības iestādē. Pētījuma aktualitāte izriet no galvenajiem principiem kvalitātes veicināšanai iekļaujošā izglītībā (Eiropas speciālās izglītības aģentūra, 2009). Galveno principu izstrādāšanas svarīgākais mērķis ir veicināt līdzdalību iekļaujošā izglītībā, nodrošinot kvalitatīvus izglītības pakalpojumus. Iekļaujošās izglītības mērķis ir paplašināt pieejamību izglītībai un veicināt visu izglītojamo līdzdalību un iespējas, lai īstenotu savu potenciālu. Pozitīvas …
Leksiskā pieeja lietišķās angļu valodas sarakstes prasmju pilveidei augstskolā
2021
Šabloniskās valodas lietojums lietišķajā komunikācijā palīdz ziņu padarīt īsāku un skaidrāku, kas ir svarīgi, lai panāktu veiksmīgas biznesa attiecības un sasniegtu komunikatīvos mērķus. Mērķis bija izpētīt, cik efektīvi būtu piemērot leksisko pieeju mācot vēstuļu rakstīšanu lietišķās angļu valodas kontekstā. Pielietotā pētniecības metode bija gadījuma izpēte. Datu iegušanas metodes bija aptaujas un testi. Pētījuma dalībnieki bija trīsdesmit pilna laika bakalaura līmeņa studenti, kas apguva programmu vienā no universitātēm Latvijā. Visiem dalībniekiem angļu valoda bija svešvaloda. Secinājumi norādīja, ka leksiskā pieeja kā metodoloģiskā stratēģija pozitīvi ietekmēja šabloniskās valodas liet…
Inequalities in Consumption Patterns over the Life Cycle and the Great Recession
2015
The aim of the study is to analyse the relationship between recession, population structure and consumption behaviour over the life cycle. To this aim, we consider three clusters of non-durable expenditures such as food at home, work-related and core expenditures. The analysis has been performed on micro data on the Household Budgets for the period 1997-2013. Based on life cycle theory, two statistical models has been estimated, viz. a pre-crisis (1997-2007) and a great recession period (2008-2013) model. The study shows that the recession has entailed a reduction of the average expenditure for each category of consumption, and the intensity of the reduction is different among households an…
Il lifelong learning come vocazione ontologica “nell’Essere Più”
2022
Nel passato il paradigma fordista ha affidato alla politica e alla società di produrre capitale umano e sociale poiché in grado di consumare la produttività e l’efficienza del mercato (Margiotta, 2015). Oggi invece la produzione fa leva sulle ambizioni e capacità di tanti individui che si danno da fare. Saper gestire la propria formazione continua è una competenza che ogni insegnante deve sviluppare perché essa subordina l’acquisizione e lo sviluppo di tutte le altre. Emerge dunque la necessità di una policy educativa e formativa in grado di promuovere opportunità realizzativa, la riscoperta dell’intelligenza personale e comunitaria come motore generativo di estrazione di valore. Il dir…
