Un sistema per la concimazione spazialmente variabile
2005
Lo scopo del lavoro è quello di misurare il tempo e la distanza di regolazione di un sistema per l’applicazione di fattori produttivi a dosi spazialmente variabili, progettato, sviluppato, messo a punto e già sperimentato positivamente per il diserbo dalla Sezione Meccanica del Dipartimento I.T.A.F. Tale sistema è stato sperimentato per la concimazione spazialmente variabile, installando, su uno spandiconcime ad azione centrifuga a due dischi di distribuzione opportunamente modificato, due diversi tipi di attuatori, collegati al sistema di regolazione delle luci di caduta del concime. E’ risultato che, a parità di variazione di dose, la distanza di regolazione del sistema, con entrambi gli …
The school inclusion of students with special needs. Bullying and school adjustment in students with neurodevelopmental disorders and other special e…
2023
Introduction Bullying is the most common type of violence in school. Nearly one third of students worldwide are bullied, with negative physical, psychological, relational consequences for victims, perpetrators and bystanders. Bullying is a group process that involves school climate in promoting or inhibiting aggressive behaviors: positive relationships with peers and teachers are protective factors against victimization, while problems in school adjustment are related to bullying in both victims and bullies. Individuals owning to minorities are more at risk for bullying, because they differ from the group. Among these, students with disabilities and other special educational needs (SEN) are…
Sexual and postmating reproductive isolation between allopatric Drosophila montana populations suggest speciation potential
2011
Background - Widely distributed species with populations adapted to different environmental conditions can provide valuable opportunities for tracing the onset of reproductive incompatibilities and their role in the speciation process. Drosophila montana, a D. virilis group species found in high latitude boreal forests in Nearctic and Palearctic regions around the globe, could be an excellent model system for studying the early stages of speciation, as a wealth of information concerning this species' ecology, mating system, life history, genetics and phylogeography is available. However, reproductive barriers between populations have hereto not been investigated. Results - We report both pr…
Diskriminācijas aizlieguma saturs starptautiskajos investīciju strīdos
2019
Diskriminācijas aizliegums ir viens no pamatprincipiem starptautisko investīciju tiesībās un starptautisko investīciju aizsardzības režīmos. Lai gan šis princips ir sastopams gandrīz ikkatrā investīciju aizsardzības režīmu nodibinošajā dokumentā, tā definīcija un saturs joprojām ir neskaidri, izraisot diskusijas starptautiskajā sabiedrībā. Principa interpretācija ir atstāta tiesu un šķīrējtiesu ziņā, kas nav spējušas nonākt pie vienota un skaidra diskriminācijas aizlieguma satura. Šī darba mērķis ir noskaidrot līdzīgās iezīmes principa definēšanā un piemērošanā, ko ir izvirzījušas tiesas un šķīrējtiesas risinot starptautiskos investīciju strīdus, tādējādi definējot diskriminācijas aizliegum…
Startup-sijoittajat portinvartijoina journalismin kentällä
2023
Startup-yritysten roolista journalismin uudistajina on ristiriitaisia näkemyksiä, mutta niiden katsotaan kuitenkin yleisesti tuovan alalle uusia toimintamalleja ja haastavan vakiintuneita instituutioita. Sijoittajien merkitys journalistisen startup-yrittämisen kentällä on jäänyt vähälle huomiolle, vaikka he viime kädessä päättävät, millaiset yritykset saavat mahdollisuuden käynnistää tai kehittää toimintaansa. Tässä tutkimuksessa tarkastelemme startup-sijoittajia SCOT-teorian kehyksessä journalismin portinvartijoina ja journalistiseen metadiskurssiin osallistuvina keskustelijoina, joilla on alan kehittämiseen liittyvää valtaa ja vastuuta. Tavoitteenamme on tarkentaa kuvaa siitä, millaiset a…
Postmodernisma stilistiskie apsekti vizuālās identitātes izveidē
2021
Diplomdarba tēma ir “Postmodernisma stilistiskie aspekti vizuālās identitātes veidošanā”. Balstoties uz teorētisku un empīrisku pētījumu, darba mērķis ir izveidot vizuālo identitāti konceptuālai kafejnīcai “CES–it-IS”, izmantojot postmodernisma grafikas dizainam raksturīgus vizuālos izteiksmes līdzekļus. Teorētiskajā daļā aprakstīts vizuālās identitātes jēdziens, modernisms un stili, kas ietekmēja postmodernisma rašanos, postmodernisms mākslā un dizainā. Kā arī – postmodernās grafiskā dizaina kustības un ievērojamākās dizaina sistēmas. Lai veiksmīgi realizētu darba mērķi, darba empīriskajā daļā tika veikta ēdināšanas iestāžu vizuālo identitāšu analīze. Rezultātā tika noskaidroti postmoderni…
Impact of supplier-specific investments in inter-organisational information systems on strategic electronic coordination: the moderation effect of bu…
2018
Abstract This paper examines the factors which influence sharing of the strategic information (in other words, electronic coordination) in a buyer–supplier dyad. The antecedents of this coordination are examined rather well in the transaction cost economics (TCE) theory and resource-dependency theory (RDT), while the supply chain management perspective is contemplated. The mentioned frameworks are used in the analysis. However, the research focus is narrowed down to the exploration of the antecedents of information exchange conducted via inter-organisational information systems (IOS). The empirical analysis is based on 198 observations of Norwegian companies operating in different types of …
Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM
2014
Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…
Psychosocial Factors and Chronic Illness as Predictors for Anxiety and Depression in Adolescence
2020
Adolescence is a challenging time when emotional difficulties often arise. Self-esteem, good relationships with peers, and emotional competences can buffer the effects of these difficulties. The difficulties can be even greater when coupled with the presence of a chronic physical illness (CD). Our goal is to analyze psychosocial factors and CD as predictors for anxiety and depression. It was compared the results of structural equation models (SEM) with models based on qualitative comparative analysis (QCA) to analyze the possible influence of these variables on levels of anxiety-depression in adolescents with and without CD. The sample consisted of 681 adolescents, between 12 and 16 years o…
Effects of contextual variables on strategic investment decision-making styles: An empirical study from Pakistan.
2022
There is a gap in the literature of strategic investment decision making (SIDM) concerning the links between context variables, infrastructure and SIDM practices (or SIDM styles) in developing countries. This research aims to fill that gap. Survey data (N = 128) from the manufacturing companies listed on the Pakistan Stock Exchange was collected via an e-mailed questionnaire and visits to the companies. Data are analyzed with factor analysis and multiple regression analysis. The results reveal what we call four different SIDM styles (or emphases): managerial power-, financial analysis-, top management-, and strategy-based investing. These styles are considered to be novel perspectives on SI…
