We offer a didactic proposal about conflict and explain the results of its application intwo Secondary Education classrooms

New strategies for treatment and reuse of spent sulfidic caustic stream from petroleum industry

This work examines traditional and new routes for removal of H2S and other sulfur compounds from spent sufidic caustic (SSC). SH- (hydrogenosulfide) and S2- (sulfide) ions were quantitatively oxidized at 25 ºC using H2O2, NaOCl or a spent sulfochromic mixture. SH-/S2- ions were also removed via reaction with freshly prepared iron or manganese hydroxides, or after passing the SSC through strong basic anion exchange resins (OH- form). The treated caustic solution, as well as iron/manganese hydroxides, removed H2S from diesel samples at 25 ºC. SSC treatment via strong basic anion-exchange resins produced the treated caustic solution with the highest free alkalinity.

Traditional and transgenic strategies for controlling tomato-infecting begomoviruses

Viruses of to the family Geminiviridae are considered some of the most important pathogens in tropical and subtropical regions of the world. Members of one Geminiviridae genus, Begomovirus, have been causing severe losses, particularly in tomato (Lycopersicon esculentum) production in the Americas and the Caribbean. Several new begomoviruses have been reported in the region and, at least one, Tomato yellow leaf curl virus (TYLCV), has been brought in from the Old World via infected transplants. In addition, the recombination events that are playing an important role in Begomovirus diversity have increased the complexity of their control. This scenario has led to the search for control measures that go beyond traditional host genetic resistance, chemical controls and cultural practices. In this review, besides the recommended classical control measures, transgenic approaches will be discussed, as well as the mechanisms involved in their successful control of viruses.

Certificate Handling Middleware for Mobile Devices

The purpose of this thesis was to study how certificates could be used to improve security of mobile devices. In the theoretical part the usage of certificates to improve security is explained. In the practical part a concept of certificate handling middleware is introduced and implemented. This is to demonstrate what kind of functionality is needed to provide an improvement over the current situation in security with mobile devices. The certificate handling middleware is a concept that would work better if implemented directly into mobile device's core functionality. Many of the mobile devices have a certificate store to some degree and often it is not used to store other people's certificates. A certificate store combined with address book and added with possibility to add attributes to the people such as group memberships would be sufficient to satisfy the needs of many emerging sharing and social applications.

The role of power relations in strategic supply management – A value net approach

Supplier relationships are key elements of supply management and thus have attracted substantial research interest among academics and practitioners. The collaborative nature of relationships has been the focus of the mainstream research, and limited interest has been channelled towards power in buyer–supplier relationships. However, power is one of the key factors determining the outcomes in many business relations. Hence, one of the main objectives of this dissertation is to clarify how power may influence the nature of buyer–supplier relationships and, moreover, the depth of collaboration. Another main objective is to clarify the role of power relations in strategic supply management. Given the different nature of relationships, the firm needs divergent strategies in its supply management in order to handle them efficiently. Power has been identified as one of the factors that affect the nature of buyer–supplier relationships, and firms should thus develop strategies for handling power relations. Three research questions are addressed in pursuit of these objectives, the aim being to clarify the sources of power, the influence of power on collaboration, and the role of buyer–supplier relationships in the firm’s supply strategy. This dissertation has two parts. The first part provides a synthesis of the overall dissertation, and the second part comprises five complementary research papers. The qualitative research method is applied in an empirical case study from the Finnish food industry. The main contribution of this dissertation is that it clarifies the role of power relations in strategic supply management in value nets, and discloses the nature of power as an influencing factor in supplier relationships. It extends the discussion on power in buyer– supplier relationships in highlighting the context of networks and raising the question of network effects on power relations. It also illustrates how power positions and power relations in value nets can be determined based on the sources of power of the network actors, and shows their influence on collaboration.

Simplified sample handing in mass spectrometry based protein research - focus on protein phosphorylation

The human genome comprises roughly 20 000 protein coding genes. Proteins are the building material for cells and tissues, and proteins are functional compounds having an important role in many cellular responses, such as cell signalling. In multicellular organisms such as humans, cells need to communicate with each other in order to maintain a normal function of the tissues within the body. This complex signalling between and within cells is transferred by proteins and their post-translational modifications, one of the most important being phosphorylation. The work presented here concerns the development and use of tools for phosphorylation analysis. Mass spectrometers have become essential tools to study proteins and proteomes. In mass spectrometry oriented proteomics, proteins can be identified and their post-translational modifications can be studied. In this Ph.D. thesis the objectives were to improve the robustness of sample handling methods prior to mass spectrometry analysis for peptides and their phosphorylation status. The focus was to develop strategies that enable acquisition of more MS measurements per sample, higher quality MS spectra and simplified and rapid enrichment procedures for phosphopeptides. Furthermore, an objective was to apply these methods to characterize phosphorylation sites of phosphopeptides. In these studies a new MALDI matrix was developed which allowed more homogenous, intense and durable signals to be acquired when compared to traditional CHCA matrix. This new matrix along with other matrices was subsequently used to develop a new method that combines multiple spectra from different matrises from identical peptides. With this approach it was possible to identify more phosphopeptides than with conventional LC/ESI-MS/MS methods, and to use 5 times less sample. Also, phosphopeptide affinity MALDI target was prepared to capture and immobilise phosphopeptides from a standard peptide mixture while maintaining their spatial orientation. In addition a new protocol utilizing commercially available conductive glass slides was developed that enabled fast and sensitive phosphopeptide purification. This protocol was applied to characterize the in vivo phosphorylation of a signalling protein, NFATc1. Evidence for 12 phosphorylation sites were found, and many of those were found in multiply phosphorylated peptides

Att förstå det stora i det lilla : byskolan som pedagogik, kultur och struktur

I det lilla sammanhanget synliggörs de stora frågorna om både pedagogik, kultur och struktur och om samverkan mellan dem. Studiet av de minsta enheterna i den finländska utbildningen ger kunskap om det viktiga i pedagogiska relationer och i skolgemenskaper, men synliggör också samhällsskeendets inbyggda konflikter om mål och värderingar. Det övergripande syftet med studien är att fördjupa kunskapen om de små skolornas pedagogiska, kulturella och strukturella innebörd och betingelser. Genom djupintervjuer med 12 finlandssvenska lärare i byskolor med färre än 30 elever, analys av skolindragningsdebatt och utbildningspolitiska styrdokument, samt genom teoretiskt förankrade reflektioner skapas en förståelse av såväl lärares arbete och pedagogiska tänkande som skolans funktion i samhället. Avhandlingen byggs upp enligt ett hermeneutiskt och narrativt tänkande. I studien framkommer att byskollärares pedagogiska tänkande syftar till det enskilda barnets optimala och balanserade helhetsutveckling i en gemenskap, där det är centralt att finna den pedagogiska balansen och möjligheten inom kontinuum mellan bl.a. elevbemyndigande och beledsagande. De pedagogiska intentionerna bär syftet att ge rötter och vingar, samhörighet och frihet. I lärarnas beskrivningar uttrycks en sammanvävning mellan deras pedagogiska intentioner och de kontextuella möjligheterna att realisera dessa. Byskollärarna är bärare av en pedagogisk professionalitet som utvecklas i relation till arbetets betingelser. Det praktiska yrkeskunnandet innefattar en balansgång mellan å ena sidan systematik och organisering och å andra sidan flexibilitet och frihet. Att samma lärare handhar eleverna en lång tid är en pedagogisk möjlighet och utmaning. I lärarnas berättelser aktualiseras vad balansgången i en god pedagogisk relation innebär. Både lärare och elever fostras in i en särskild skolkultur och undervisningskultur, i en växelverkan. Yrkeskulturen präglas av olika former av samverkan, både med skolans hela personal som ett teamarbete och med lokalsamhället. Lärarna uttrycker god arbetstrivsel, men friheten och ansvaret i arbetet kan vara både stimulerande och betungande. I en metaanalys skapas teoretiska modeller för vad arbete i närhetens och litenhetens spänningsfält kan innebära och hur det kan påverka lärares professionella utveckling och ork. Den lilla byskolan relaterad till en större samhällskontext öppnar för frågor om vad kvalitet innebär och vilka värderingar som är riktgivande inom utbildningsplanering. Kampen för kontinuiteten i byskolans berättelse tolkas som en kamp för det lokala rummet, för gemenskap, existens, framtid, likvärdighet och trygghet. Kampen för byskolan är ett försvar av både lokal livskvalitet och pedagogisk kvalitet för den enskilde eleven. I det övergripande kulturella sammanhanget synliggörs motsättningar. Det verkar finnas en inbyggd konflikt i utbildningsplaneringens föresatser att samtidigt uppnå jämlikhet, kostnadseffektivitet och kvalitet. En teoretisk modell synliggör hur pedagogik, kultur och struktur samverkar inom utbildning/byskola och påverkar lärares och elevers handlingsutrymme.

Kropp, handling och ritual: hur förstå religion och personer med grava funktionshinder?

Arbetet som omsorgspräst sedan 1990 har väckt många frågor samband med mötet med personer som har grava funktionshinder. Det har skett framför allt i skriftskolor och konfirmationsundervisning från år 1984 framåt. Men speciellt samarbetet med fysioterapeut Karin Isaksson fick betydelse. Vi inbjöd personer med svåra spänningar och lite aktivitet att delta i en grupp med avslappning och kontemplativ sång. Gruppen (1997-2001)som höll på en timme gav uppmuntrande resultat. Men det var lättare för Isaksson att tänka på det i termer av avslappning och fysiskt välbefinnande då det för mig ingick sådant som helig närvaro och tystnad i mötet med deltagarna. Det resulterade så småningom i ett forskningsprojekt som jag kallar för Aaa-gruppen efter de kontemplativa intonationsövningar som ingår i ritualen. (AÅOM). Sex par (deltagare och handledare) anmälde sig till forskningsprojektet. Materialet samlades in åren 2002-2003. Aaa-gruppens ritual består av kontemplativ gregoriansk sång(intonationsövningar + antifoner som Kyrie eleison, Hosanna Filio David, Sanctus, Non i solo pane - Människan skall icke leva av bröd allenast och Fader Vår bönen.) Samarbetet i Aaa-gruppen mellan deltagare och handledare omfattade taktil stimulans (beröring enligt strykningar och ”Keep in Touch”) Materialet samlades in som observationsprotokoll, frågeformulär och intervjuer. Materialet har jag använt för att reflektera över hur vi kan förstå Aaa-gruppen och verklighet. I avhandlingen utgår jag från tankar om kontextens betydelse för en förståelse. Jag uppfattar att tre sammanhang är av betydelse för förståelsen. Dem har jag kallat för omsorgssammanhang, religiöst sammanhang och forskarsammanhang. I avhandlingen användes tre perspektiv som jag kallar för dialogfilosofi, neurofilosofi och livsformsfilosofi för att reflektera materialet. Den nära relationen mellan deltagare och handledare i Aaa-gruppen kan förstås ur olika sammanhang. Resultatet av den religionsfilosofiska reflektionen är att sammanhangen liksom de olika filosofiska perspektiven kompletterar och ger en mångsidig förståelse för religion och personer med grava funktionshinder. Reflektionen berör grundläggande frågeställningar kring kropp och medvetande och frågan om språk (nonverbalt och verbalt) och verklighet. En dualistisk uppfattning om jaget, som delbart i kropp och medvetande, avisas till förmån för ett så kallat ”kroppsjag”. Religion i Aaa-gruppen kan förstås som ett möte i en nära relation. Ett möte som är nonverbalt men inbegriper en mänskligt förhållningssätt som inom dialogfilosofin kan beskrivas med ordparet Jag-Du.

Equivalence and translation strategies in multilingual thesaurus construction

In the present dissertation, multilingual thesauri were approached as cultural products and the focus was twofold: On the empirical level the focus was placed on the translatability of certain British-English social science indexing terms into the Finnish language and culture at a concept, a term and an indexing term level. On the theoretical level the focus was placed on the aim of translation and on the concept of equivalence. In accordance with modern communicative and dynamic translation theories the interest was on the human dimension. The study is qualitative. In this study, equivalence was understood in a similar way to how dynamic, functional equivalence is commonly understood in translation studies. Translating was seen as a decision-making process, where a translator often has different kinds of possibilities to choose in order to fulfil the function of the translation. Accordingly, and as a starting point for the construction of the empirical part, the function of the source text was considered to be the same or similar to the function of the target text, that is, a functional thesaurus both in source and target context. Further, the study approached the challenges of multilingual thesaurus construction from the perspectives of semantics and pragmatics. In semantic analysis the focus was on what the words conventionally mean and in pragmatics on the ‘invisible’ meaning - or how we recognise what is meant even when it is not actually said (or written). Languages and ideas expressed by languages are created mainly in accordance with expressional needs of the surrounding culture and thesauri were considered to reflect several subcultures and consequently the discourses which represent them. The research material consisted of different kinds of potential discourses: dictionaries, database records, and thesauri, Finnish versus British social science researches, Finnish versus British indexers, simulated indexing tasks with five articles and Finnish versus British thesaurus constructors. In practice, the professional background of the two last mentioned groups was rather similar. It became even more clear that all the material types had their own characteristics, although naturally not entirely separate from each other. It is further noteworthy that the different types and origins of research material were not used to represent true comparison pairs, and that the aim of triangulation of methods and material was to gain a holistic view. The general research questions were: 1. Can differences be found between Finnish and British discourses regarding family roles as thesaurus terms, and if so, what kinds of differences and which are the implications for multilingual thesaurus construction? 2. What is the pragmatic indexing term equivalence? The first question studied how the same topic (family roles) was represented in different contexts and by different users, and further focused on how the possible differences were handled in multilingual thesaurus construction. The second question was based on findings of the previous one, and answered to the final question as to what kinds of factors should be considered when defining translation equivalence in multilingual thesaurus construction. The study used multiple cases and several data collection and analysis methods aiming at theoretical replication and complementarity. The empirical material and analysis consisted of focused interviews (with Finnish and British social scientists, thesaurus constructors and indexers), simulated indexing tasks with Finnish and British indexers, semantic component analysis of dictionary definitions and translations, coword analysis and datasets retrieved in databases, and discourse analysis of thesauri. As a terminological starting point a topic and case family roles was selected. The results were clear: 1) It was possible to identify different discourses. There also existed subdiscourses. For example within the group of social scientists the orientation to qualitative versus quantitative research had an impact on the way they reacted to the studied words and discourses, and indexers placed more emphasis on the information seekers whereas thesaurus constructors approached the construction problems from a more material based solution. The differences between the different specialist groups i.e. the social scientists, the indexers and the thesaurus constructors were often greater than between the different geo-cultural groups i.e. Finnish versus British. The differences occurred as a result of different translation aims, diverging expectations for multilingual thesauri and variety of practices. For multilingual thesaurus construction this means severe challenges. The clearly ambiguous concept of multilingual thesaurus as well as different construction and translation strategies should be considered more precisely in order to shed light on focus and equivalence types, which are clearly not self-evident. The research also revealed the close connection between the aims of multilingual thesauri and the pragmatic indexing term equivalence. 2) The pragmatic indexing term equivalence is very much context-depended. Although thesaurus term equivalence is defined and standardised in the field of library and information science (LIS), it is not understood in one established way and the current LIS tools are inadequate to provide enough analytical tools for both constructing and studying different kinds of multilingual thesauri as well as their indexing term equivalence. The tools provided in translation science were more practical and theoretical, and especially the division of different meanings of a word provided a useful tool in analysing the pragmatic equivalence, which often differs from the ideal model represented in thesaurus construction literature. The study thus showed that the variety of different discourses should be acknowledged, there is a need for operationalisation of new types of multilingual thesauri, and the factors influencing pragmatic indexing term equivalence should be discussed more precisely than is traditionally done.

Regional innovation strategies and sustainability in selected EU countries

This study focuses on regional innovation strategy (RIS) and sustainability aspects in selected regions of European Union (EU) countries. It is known that RIS helps a region to innovate locally and to compete globally and it is considered as one of the main policy tools of the EU for innovation support at a regional level. This study is conducted to explore the existence and adoption of RIS in different regions of selected EU countries, and to highlight and compare regional RIS characteristics. The study is also aimed at identifying the factors that characterise the formulation and implementation of RIS as well as the problems associated thereof. In this study, six regions of EU countries are considered: Päijät-Häme Region (Finland); London Region (United Kingdom); Mid-West Region (Ireland); Veneto Region (Italy); Eastern Region (Poland); and West Region (Romania). Data and information are collected by sending questionnaires to the respective regional authorities of these selected regions. Based on the gathered information and analysis, RIS or equivalent strategy document serves as a blueprint for forwarding innovative programmes towards regional sustainability. The objectives of RIS in these regions are found to be dependent on the priority sectors and state of the region’s development. The current environmental sustainability aspects are focused on eco-design, eco-products, and eco-innovation, although each region also has its own specific aspects supported by RIS. Likewise, regional policies typically follow the RIS yet translated in various sectoral focus or priority areas. The main enhancing factors supporting RIS among selected regions have some similarities and variations; among others, some regions are strongly supported by EU while others have support from own regional agencies, organisations and professional networks. RIS implementation is not without challenges and despite the differences in challenges, almost all of reviewed regions consider financial resource as a common problem. Generally, it is learned from this study that RIS and regional sustainability are reinforcing each other mutually. In this study, the strong focus is given towards environmental sustainability in the regions although regional sustainability also includes economic and social aspects. A well-focused and prioritised RIS is beneficial for regional sustainable development.
