Forskningens syfte var att bidra med en ny kunskapssyntes om vad det innebär att leda förändring ur ett vårdvetenskapligt perspektiv. Vårdledaren har, speciellt vid större förändringar inom organisationen, en stor betydelse för hur vårdandet förvaltas genom att hålla den vårdande traditionen levande och genom formningen av den vårdande kulturen och vårdgemenskapen. Den övergripande hermeneutiska forskningsansatsen med tillämpning av metodologisk triangulering har influerats av Gadamers, Ricoeurs och Ödmans syn på hermeneutik med förståelse och förklaring som kompletterar varandra. Forskningens övergripande frågeställning ”Vad innebär det att leda förändring ur ett vårdvetenskapligt perspektiv?” förankrades i de fyra underliggande frågeställningarna. Den första frågeställningen berörde meningsinnehållet i begreppet förändring samt dess gestaltning. Metoden var en hermeneutisk begreppsbestämning på en ontologisk och kontextuell nivå enligt Koorts metod för begreppsbestämning. Genom en personalenkät undersöktes personalens åsikter (totalt 597 personer) om den kommande fusionen och förändringen samt deras förväntningar på ledarna under förändringsprocessen för att få svar på vad förutsättningarna var för en förändring eller förändringsprocess med avsedda mål och effekter. Svaret på hur vårdledaren och dennes uppgifter gestaltades vid en förändring samt hur vårdledarna uppfattade förändring och den kommande förändringsprocessen erhölls genom djupintervjuer med vårdledare (17). Av resultatet framgår att vårdledaren leder förändring genom att leda relationer, processer och kultur och genom ett stödjande, reflekterande och kulturbärande ledarskap med syftet att åstadkomma en verklig och hållbar förändring. För att åstadkomma en verklig och hållbar förändring, dvs. en inre omgestaltning och omdaning som vardande, förutsätts dock att både tankemönster och handlanden förändras. Riktningen och insatserna för förändringen skall ha sin grund i en tydlig och meningsfull målsättning och vision utgående från en gemensam värdegrund. En arena för dialog borde utvecklas så att förändringens liksom även vårdandets vision och mission förankras och utvecklas till handling och förändring. Vårdledarens primära uppgift eller mission var att tillhandahålla varje individuell patient en god vård. Den primära missionen var med andra ord att med ansvarsfullhet tjäna vårdandet sak utgående från ett etiskt förhållningssätt. I tjänande av vårdandets sak fanns dock en tillit till att förändringen gagnar patienten och hans eller hennes vård, men vårdledarnas anpassning till förändringen var utan djupare engagemang. Vårdledarna kände även en oro för sitt uppdrag som vårdledare, vårdarbetets ställning och mandatet som patientens advokat. Vårdledaren är också en kulturbärare, vilket innebär att även kulturen har betydelse under en förändringsprocess. Genom att leda kulturen skapar vårdledaren en öppen, bekräftande och evidensbaserad atmosfär med centrala värderingar som ger uttryck för den rådande andan och kulturen.

Open source and open source software development have been interesting phenomena during the past decade. Traditional business models do not apply with open source, where the actual product is free. However, it is possible to make business with open source, even successfully, but the question is: how? The aim of this study is to find the key factors of successfully making business out of commercial open source software development. The task is achieved by finding the factors that influence open source projects, finding the relation between those factors, and find out why some factors explain the success more than others. The literature review concentrates first on background of open innovation, open source and open source software. Then business models, critical success factors and success measures are examined. Based on existing literature a framework was created. The framework contains categorized success factors that influence software projects in general as well as open source software projects. The main categories of success factors in software business are divided into community management, technology management, project management and market management. In order to find out which of the factors based on the existing literature are the most critical, empirical research was done by conducting unstructured personal interviews. The main finding based on the interviews is that the critical success factors in open source software business do not differ from those in traditional software business or in fact from those in any other business. Some factors in the framework came out in the interviews that can be considered as key factors: establishing and communicating hierarchy (community management), localization (technology management), good license know-how and IPR management (project management), and effective market management (market management). The critical success factors according to the interviewees are not listed in the framework: low price, good product and good business model development.

A molecular epidemiological study was performed with Babesia bigemina isolates from five geographical regions of Brazil. The genetic analysis was done with random amplification of polymorphic DNA (RAPD), repetitive extragenic palindromic elements-polymerase chain reaction (REP-PCR) and enterobacterial repetitive intergenic consensus sequences-polymerase chain reaction (ERIC-PCR) that showed genetic polymorphism between these isolates and generated fingerprinting. In RAPD, ILO872 and ILO876 primers were able to detect at least one fingerprinting for each B. bigemina isolate. The amplification of B. bigemina DNA fragments by REP-PCR and ERIC-PCR gave evidence for the presence in this haemoprotozoan of the sequences described previously in microorganisms of the bacterial kingdom. For the first time it was demonstrated that both techniques can be used for genetic analysis of a protozoan parasite, although the ERIC-PCR was more discriminatory than REP-PCR. The dendogram with similarity coefficient among isolates showed two clusters and one subcluster. The Northeastern and Mid-Western isolates showed the greatest genetic diversity, while the Southeastern and Southern isolates were the closest. The antigenic analysis was done through indirect fluorescent antibody technique and Western blotting using a panel of monoclonal antibodies directed against epitopes on the merozoite membrane surface, rhoptries and membrane of infected erythrocytes. As expected, the merozoite variable surface antigens, major surface antigen (MSA)-1 and MSA-2 showed antigenic diversity. However, B cell epitopes on rhoptries and infected erythrocytes were conserved among all isolates studied. In this study it was possible to identify variable and conserved antigens, which had already been described as potential immunogens. Considering that an attenuated Babesia clone used as immunogen selected populations capable of evading the immunity induced by this vaccine, it is necessary to evaluate more deeply the cross-protection conferred by genetically more distant Brazilian B. bigemina isolates and make an evaluation of the polymorphism degree of variable antigens such as MSA-1 and MSA-2.

Tutkimuksessa tarkastellaan nuorten antamia merkityksiä elämykseksi nimetylle kokemukselle ja tunteelle. Tavoitteena on ollut selvittää elämysten kokemista nuorten näkökulmasta ja suhteuttaa nuorten kokemuksilleen antamia merkityksiä laajemmin nuoruutta ja elämyksien kokemista käsittelevään yhteiskunnalliseen keskusteluun. Elämysten merkityksellistämistä analysoidaan suhteessa identiteetin muodostukseen. Yksilöllisesti koetut elämykset saavat merkityksensä diskursiivisesti rakentuneen todellisuuden ympäröimänä. Tutkimus paikantuu sosiologisen nuorisotutkimuksen ja tunteiden tutkimuksen alaan sekä metodologisesti fenomenologis-konstruktivistisen tutkimuksen alaan. Tutkimuksen taustalla on elämyshakuisuutta käsittelevä teoria. Elämyshakuisuuden tulkinta fenomenologisesta viitekehyksestä tuo käsitteen ymmärtämiseen uuden ulottuvuuden. Elämyshakuisuus kuvaa asennoitumistapaa eli sitä, miten yksilö orientoituu ympäröivään maailmaan. Tällöin ei edellytetä intentionaalisten tekojen tietoista luonnetta. Toiminnalliset prosessit muovautuvat vuorovaikutuksen myötä samaan tapaan kuin ihminen ruumiillisena subjektina muovautuu. Tutkimuksen aineisto koostuu lukion ensimmäisen luokan oppilaiden kirjoituksista (519 kpl), lastensuojeluinstituutioissa ja kuntoutuskeskuksissa asuvien nuorten yksilöteemahaastatteluista (16 nuorta) sekä seikkailualan asiantuntijoiden teemahaastatteluista (20 aikuista). Nuorten kirjoitukset on kerätty vuosina 1996–1997 ja 2002–2003. Aineiston analyysi on aineistolähtöinen. Erilaiset osa-aineistot työssäni avaavat erilaisia näkökulmia elämysten kokemiseen. Aineistojen analyysi ja tutkimukset teoreettiset lähtökohdat ovat rakentuneet analyysin edetessä ja vuorovaikutussuhteessa toisiinsa. Nuorten elämyksiä käsittelevä kerronta on moninaista ja elämyksiä koetaan erilaisissa tilanteissa. Elämykselle ei ole yhtä määritelmää, kokemisen paikkaan tai kokemisen syytä vaan kokemuksen merkitys rakentuu tilanteisesti. Elämys kuitenkin erottuu muista kokemuksista sen muistettavuuden, ainutlaatuisuuden, uutuuden ja intensiivisyyden perusteella. Nuorten elämyksellisissä hetkissä korostuvat harrastusten yhteydessä koetut uudet, erilaiset, yhteisöllisesti jaetut, mutta myös maailmaa nuorille avaavat itsenäisyyden tunnetta ja hallintaa tuottavat kokemukset. Yksi merkittävä uusia elämyksiä ja tietoa tuottava asia nuorten elämässä on seurustelu. Myös matkailu, erilaiset retket ja leirit olivat nuorille elämyksiä tuottavia tilanteita. Kaikilla nuorilla ei kuitenkaan ole sellaisia harrastuksia, joihin he olisivat sitoutuneita tai joissa he pääsisivät ilmaisemaan itseään ja kokemaan onnistumista. Nuorten elämyksiä käsittelevissä hetkissä nuorten vapaa-ajan toiminta, ympäristö ja sosiaaliset suhteet ovat keskeisessä asemassa. Nuoret eivät ensisijaisesti ajatelleet itse etsivänsä tai toisten nuorten etsivän elämyksiä viihdeteollisuuden tuottamista asioista. Elämyksissä arvostettiin aitoutta ja koettu tunne määritti sitä, oliko jokin koettu elämyksenä vai ei. Toisaalta erilaisten päihteiden todettiin mahdollisesti tuottavan elämyksiä, mutta niidenkin yhteydessä korostettiin usein muita asioita kokemusta rakentavina. Nuorten elämyskokemuksissa toisten nuorten merkitys, luottamus, läheisyyteen ja hyväksyntään liittyvät kokemukset korostuvat. Myös aikuisten asiantuntijoiden omaa nuoruutta käsittelevät elämykset olivat emotionaaliselta merkitykseltään hyvin samanlaisia kuin tämän päivän nuorten esittämät. Elämyksiksi miellettyjä kokemuksia pidettiin arvokkaina. Niiden uskottiin suuntaavan yksilön toimintaa.

Hystricognathi represent a monophyletic taxon within Rodentia. Since phylogenetically analyzed morphological systems are essential for revealing evolutionary processes, this study identifies evolutionary character transformations on the stem lineage of Hystricognathi as derived from the author's own work and the literature. Data so far indicate that evolutionary transformations in the rostral head region, the loss of tactile ability in the outer nasal skin and the mobile arrangement of the associated cartilage, were allied with a switch from omnivorous to herbivorous and fiber-rich nutrition. Additional character transformations in the skull assist in digesting such food. Structures associated with reproduction and placentation show a remarkable pro portion of derived character conditions: the chorioallantoic placenta has a ring-shaped organization and growth structure which optimizes the capacity for passive diffusion, a subplacenta occurred as a specialized region responsible for placental invasion and the inverted yolk sac facilitates substance exchange with the main placenta. Finally, precocial newborns evolved as a derived condition within Rodentia. All things considered, a mode of reproduction is indicated, which does not demand excessive additional energy intake by the mother and is in accordance with her low energetic diet. Hystricognathi possess major character transformations that represent prerequisites for their successful radiation at the time when more open ecosystems and grasslands evolved during Earth history. The analysis resulted in the reconstruction of a life-near picture of the hystricognath stem species pattern with high explanatory power in terms of changes in space and time and their interdependence with biodiversity.

In this Thesis various aspects of memory effects in the dynamics of open quantum systems are studied. We develop a general theoretical framework for open quantum systems beyond the Markov approximation which allows us to investigate different sources of memory effects and to develop methods for harnessing them in order to realise controllable open quantum systems. In the first part of the Thesis a characterisation of non-Markovian dynamics in terms of information flow is developed and applied to study different sources of memory effects. Namely, we study nonlocal memory effects which arise due to initial correlations between two local environments and further the memory effects induced by initial correlations between the open system and the environment. The last part focuses on describing two all-optical experiment in which through selective preparation of the initial environment states the information flow between the system and the environment can be controlled. In the first experiment the system is driven from the Markovian to the non- Markovian regime and the degree of non-Markovianity is determined. In the second experiment we observe the nonlocal nature of the memory effects and provide a novel method to experimentally quantify frequency correlations in photonic environments via polarisation measurements.

Choice of industrial development options and the relevant allocation of the research funds become more and more difficult because of the increasing R&D costs and pressure for shorter development period. Forecast of the research progress is based on the analysis of the publications activity in the field of interest as well as on the dynamics of its change. Moreover, allocation of funds is hindered by exponential growth in the number of publications and patents. Thematic clusters become more and more difficult to identify, and their evolution hard to follow. The existing approaches of research field structuring and identification of its development are very limited. They do not identify the thematic clusters with adequate precision while the identified trends are often ambiguous. Therefore, there is a clear need to develop methods and tools, which are able to identify developing fields of research. The main objective of this Thesis is to develop tools and methods helping in the identification of the promising research topics in the field of separation processes. Two structuring methods as well as three approaches for identification of the development trends have been proposed. The proposed methods have been applied to the analysis of the research on distillation and filtration. The results show that the developed methods are universal and could be used to study of the various fields of research. The identified thematic clusters and the forecasted trends of their development have been confirmed in almost all tested cases. It proves the universality of the proposed methods. The results allow for identification of the fast-growing scientific fields as well as the topics characterized by stagnant or diminishing research activity.

This work aims to carry out a comparative analysis using RAPD molecular markers in four Commelina weed species from the state of Paraná and C. benghalensis populations from the states of Paraná and São Paulo, Brazil. The genomic plant DNA sample was extracted from the leaves, separated, randomly fragmented and amplified by PCR. Random amplified polymorphic DNA fragments (RAPD markers) were analyzed by using POPGENE statistical program. Eighty-five primer sequences were tested but only three were suitable as molecular markers producing 37 DNA polymorphic fragments for comparisons among four Commelina species and 22 polymorphic fragments for comparisons among C. benghalensis populations. The results showed that there were inter-specific and intra-specific genetic variabilities among Commelina plant genera. Genetic diversity analysis between species indicated four mono-specific clusters and it was suggested to keep C. villosa as one species. Regarding the intra-specific genetic variability of C. benghalensis alone, three groups were verified, although there were 13 populations from two geographical areas. However, these clusters do not correspond to the distinct characteristics verified.

Can crowdsourcing solutions serve many masters? Can they be beneficial for both, for the layman or native speakers of minority languages on the one hand and serious linguistic research on the other? How did an infrastructure that was designed to support linguistics turn out to be a solution for raising awareness of native languages? Since 2012 the National Library of Finland has been developing the Digitisation Project for Kindred Languages, in which the key objective is to support a culture of openness and interaction in linguistic research, but also to promote crowdsourcing as a tool for participation of the language community in research. In the course of the project, over 1,200 monographs and nearly 111,000 pages of newspapers in Finno-Ugric languages will be digitised and made available in the Fenno-Ugrica digital collection. This material was published in the Soviet Union in the 1920s and 1930s, and users have had only sporadic access to the material. The publication of open-access and searchable materials from this period is a goldmine for researchers. Historians, social scientists and laymen with an interest in specific local publications can now find text materials pertinent to their studies. The linguistically-oriented population can also find writings to delight them: (1) lexical items specific to a given publication, and (2) orthographically-documented specifics of phonetics. In addition to the open access collection, we developed an open source code OCR editor that enables the editing of machine-encoded text for the benefit of linguistic research. This tool was necessary since these rare and peripheral prints often include already archaic characters, which are neglected by modern OCR software developers but belong to the historical context of kindred languages, and are thus an essential part of the linguistic heritage. When modelling the OCR editor, it was essential to consider both the needs of researchers and the capabilities of lay citizens, and to have them participate in the planning and execution of the project from the very beginning. By implementing the feedback iteratively from both groups, it was possible to transform the requested changes as tools for research that not only supported the work of linguistics but also encouraged the citizen scientists to face the challenge and work with the crowdsourcing tools for the benefit of research. This presentation will not only deal with the technical aspects, developments and achievements of the infrastructure but will highlight the way in which user groups, researchers and lay citizens were engaged in a process as an active and communicative group of users and how their contributions were made to mutual benefit.
