Behaviour of sediment-associated silver nanoparticles and their toxicity to Lumbriculus variegatus
2017
The increasing use of silver nanoparticles (AgNPs) in industry and consumer products results in the increasing environmental concentrations of AgNPs. In the aquatic environment, sediment is the major sink for the AgNPs. The behaviour and toxicity of AgNPs in sediments is largely unknown, and therefore the potential risk to the benthic ecosystems is difficult to predict. The aim of this thesis was to study the toxicity and uptake of uncoated AgNPs (uc-AgNPs) and polyvinylpyrrolidone-coated AgNPs (PVP-AgNPs) to Lumbriculus variegatus in sediment exposures. Also, the association of AgNP-originated dissolved Ag with sediment components was studied using a sequential extraction method. Studies w…
Zinc Adsorption by Activated Carbon Prepared from Lignocellulosic Waste Biomass
2019
Sawdust was used as a precursor for the production of biomass-based activated carbon. Carbonization and activation are single-stage processes, and steam was used as a physical activation agent at 800 °
Uno strumento virtuale per il monitoraggio e il controllo di un impianto fotovoltaico a concentrazione
2014
In questa memoria si presenta una sintesi delle attività condotte nell'ambito del progetto SERPICO ("Sviluppo E Realizzazione di Prototipi di Inverter per impianti fotovoltaici a Concentrazione", PO-FESR Sicilia 2007-2013, Misura 4.1.1.2). Il progetto ha riguardato lo sviluppo di un prototipo di impianto fotovoltaico-termico a concentrazione e del relativo sistema di monitoraggio e controllo. Tale sistema permette di acquisire le quantità sia elettriche che termiche. Inoltre esso implementa un algoritmo per l'inseguimento solare utilizzato per ottimizzare la produzione di potenza.
Los Sistemas Productivos, el Aprendizaje Interno y los Resultados del Área de Producción de Baldosas-Cerámicas
2009
El objetivo de la investigacion es comprobar la validez del modelo universal de gestion en la estrategia de produccion en el sector de fabricantes de pavimentos y baldosas ceramicas espanoles. El trabajo se centra en las decisiones de infraestructura, y pretende resaltar el efecto de los recursos internos y externos sobre la ventaja competitiva del area de produccion de las empresas. Los datos utilizados corresponden a 76 empresas espanolas fabricantes de pavimentos ceramicos. Los resultados obtenidos permiten comprobar que en este sector los recursos implantados guardan poca relacion con las prioridades manifestadas. Ademas, se demuestra que la ventaja competitiva esta mas explicada por el…
Sisäisen viestinnän rooli ketterän strategian toimeenpanossa
2016
Tämän tutkimuksen tavoitteena oli selventää yhteyttä sisäisen viestinnän ja strategian välillä. Tutkimuksella selvitettiin, millainen on henkilöstön kokemus sisäisestä viestinnästä, millaiset tekijät siihen vaikuttavat ja minkälainen on henkilöstön kokemus strategiasta ja sen synnystä. Lisäksi kerättiin tietoa siitä, mikä on sisäisen viestinnän tehtävä strategian toteuttamisessa. Tutkimuksen teoriapohja muodostuu strategia käytäntönä -ajattelusta, merkityksellistämisestä, sisäisestä viestinnästä, dialogisuudesta ja tarinankerrontaan liittyvästä tutkimuskirjallisuudesta. Tutkimus on tapaustutkimus, jonka avulla pyrittiin kertomaan sisäisen viestinnän tehtävästä strategian toteuttamisessa ohj…
Omistajaohjaus, sisäinen yrittäjyys ja tuloksellisuus ammattikorkeakouluissa
2008
The first aim of the study was to produce concepts by which corporate governance, intrapreneurship and effectiveness can be studied in the context of the Finnish Universities of Applied Sciences (=henceforth the UAS or schools). The second purpose was to find out to what extent the amount of corporate governance and intrapreneurship affect the objective-orientation and effectiveness of the same schools.The concepts of owners, juridical and psychological ownership and corporate governance were analyzed according to the Agency Theory, the Human Capital Investment Theory, the Stewardship Theory and the Stakeholder Theory. The concept of intrapreneurship was analyzed as part of entrepreneurship…
Nurturing the Interpreneur
2007
Few topics in the family business literature have been studied more than management and ownership succession. In today’s competitive global economy, businesses find that innovation, growth and other entrepreneurial behaviors are necessary to survive and prosper. Ernesto Poza (1988) proposed a model for developing entrepreneurial orientations and actions in family business successors, labeling those successors interpreneurs. This study reports the results of interviews with five second-generation company owners and determines how well their experiences match the precepts of Poza’s model. Analyses find that the CEOs behaved entrepreneurially post-transition, but with few examples of conscious…
Understanding family dynasty: Nurturing the corporate identity across generations

What drives travelers' adoption of user-generated content? : A literature review
2018
User-generated content (UGC) has become an important part of travel planning, as travelers evaluate travel products based on past reviews. However, different factors account for why tourists utilize UGC. The aim of this study is to review extant studies on UGC to identify the antecedents of UGC utilization for travel planning and the theories, models, and frameworks used in these studies. A total of 54 studies from 2005 to 2016 were found. This study found that UGC adoption is determined by attributes relating to the user, the source, the content, and response variables. It also found distinct and heterogeneous theories and frameworks mainly drawn from the information systems, socio-psychol…
Improving the game with user generated content : an overview of Skyrim mod users
2017
Käyttäjien luoma sisältö on merkittävä ja kasvava osa videopelikulttuuria. Tämä tutkielma tarkastelee fanien luomia ohjelmistomuokkauksia, modeja, joilla muutetaan tai lisätään sisältöä peleissä. Tutkielman tavoitteena on selvittää modien käyttäjien motivaatiota sekä tekijöitä, jotka vaikuttavat modien käyttämisen yleisyyteen. Vaikka modeja on tutkittu akateemisesti, on tutkimus modien käyttäjien näkökulmasta jäänyt hyvin vähäiseksi. Tässä tutkimuksessa tarkasteltiin suositun roolipelin, Skyrimin saatavilla olevia modeja. Empiirinen osuus toteutettiin kuvailevana kyselytutkimuksena, joka kohdistettiin erääseen suureen Skyrim-modiyhteisöön. Kyselyssä selvitettiin modien käyttöön liittyviä ta…
