Att etablera och upprätthålla ordning i klassrummet är en komplex uppgift för lärare, särskilt för oerfarna lärare som ännu inte har etablerat egna framgångsrika metoder. Syftet med denna studie är att analysera hur lärare och elever konstruerar lokal ordning och agenda, genom empiriska observationer av daglig klassrumsinteraktion. En genomgång av tidigare forskning visar att klassrumsordning kan studeras från olika perspektiv, inklusive historiska, moraliska, kulturella och konstruktivistiska perspektiv. Denna studie utgår från ett etnometodologiskt perspektiv och teoretiska begrepp som direktiv, tillsägelser, sanktionering, mitigering, uppgradering, intersubjektivitet och ansvarsskyldighet utgör verktyg för analys av interaktionen. Observationerna dokumenterades genom videoinspelningar och fältanteckningar under lektioner i två mellanstadieklasser från två åtskilda skolor. Datamaterialet består huvudsakligen av transkriberad interaktion från 735 minuters lektionstid. Interaktionerna har analyserats med samtalsanalys och vissa inslag av etnografiska metoder. Resultaten visar att både lärare och elever kan observeras konstruera ordning genom att adressera oönskat eller störande beteende. Lärare använder många olika strategier för att ge direktiv eller korrigera elever, medan eleverna verkar imitera vissa av dessa strategier när de saktionerar sina kamrater. Lärare tenderar att mitigera sina tillsägelser på olika sätt, medan elever interagerar på ett mer omitigerat sätt gentemot varandra. De flesta korrigeringar handlade om oönskade ljud eller prat, med det fanns även andra exempel, bland annat ouppmärksamhet (enligt lärare) och handlingar som ansågs vara fusk (enligt elever). Lärare använde även förebyggande strategier för att undvika potentiella problem innan de uppstod. När elever utmanade den rådande maktstrukturen kunde det leda till uppgraderade tillsägelser från lärarens sida, eller till agendakonflikter som inte alltid hade en självklar lösning. Denna studie ger empiriska exempel på strategier som implementerats av lärare och elever vid lokal konstruktion av ordning och agenda, vilket kan vara både till praktisk hjälp för verksamma lärare och en vetenskaplig utgångspunkt för vidare studier på området. / Establishing and maintaining classroom order among students is a complex task for any teacher, especially for inexperienced teachers who have not yet established their own successful methods. The aim of this study is to analyse how teachers and students construct local order and agenda through empirical observations of everyday classroom interaction. A review of previous research reveals that classroom order can be studied from different perspectives including historical, moral, cultural and constructionist perspectives. This study uses an ethnomethodological perspective and theoretical terms such as directives, reproaches, sanctions, mitigations, upgrades, intersubjectivity and accountability as tools for analysis of interaction. Observations were documented through video recordings and field notes during lessons in two middle school classrooms, from two different schools. The data consists mainly of transcribed interaction from 735 minutes of lesson time. Data has been analysed using Conversations Analysis conventions as well as some aspects of ethnographic methods. Results show that both teachers and students can be observed to construct order by addressing unwanted or disruptive behaviour. Teachers use many different strategies to direct or reproach students, while students appear to mimic some of these when sanctioning their peers. Teachers tend to mitigate their reproaches in various ways, while peers interact in a more unmitigated manner. The main cause for reproach was unwanted noises or talking, along with a variety of other examples such as inattention (addressed by teachers) or cheating (addressed by peers). Teachers also used preventative strategies in anticipation of potential problems. When students attempt to challenge the teacher’s position of power, it can lead to upgraded reproaches or to agenda conflicts which sometimes have no simple solution. This study provides examples of strategies implemented by teachers and students when constructing order and agenda, offering a source of empirical data for practicing educators and a foundation for further research.

Background: Innovation and collaboration are deemed popular terms that are widely used and agreed on. It is implied that innovation without collaboration seems to be unlikely (Deichmann et al., 2017, Haanæs et al., 2018, Innov8rs, 2018). However, the meaning behind innovations of disruptive, incremental, or radical character remains vague and presumably differs between practitioners, just as it differs among scholars. Also, the literature only implies how collaboration can be used effectively for innovation, whilst focussing more on what forms of collaborations are existing.   Research questions: How is innovation understood in the CIC? How does the CIC work together in order to realise cross-industry collaborations for innovation?   Purpose: This study aims at investigating the variety of innovation understanding and how it is applied in collaborations, based on the views of practitioners from different companies that are part of the Cross Industry Club.   Method: This research is designed as an exploratory case study and follows a qualitative strategy with abductive reasoning. Data is collected through nine semi-structured interviews with representatives from five different companies.   Conclusion: The study revealed that practitioners have other aspects in mind which define their understanding of innovation compared to scholars. By that, the usage of innovation terminology is rather arbitrary in practice. The influence of innovation frameworks on the understanding of innovation and the collaborative work have been revealed. Innovation in a cross-industry collaboration, in its purpose and characteristics, is similar to the work of communities of practice. Challenges that appear during the emergence of a collaboration like the CIC, and values that affect the initial work towards cross-industry projects, have been identified.

Dagens taximarknad har på senare tid fått in nya innovativa aktörer som lyckats pressa ner priserna så pass mycket att de blivit ett globalt hot mot traditionella taxibolag. Dessa nya aktörer innefattar Uber och Heetch som etablerat sig inom Stockholmsregionen. Följande arbete innefattar en kartläggning av den nya moderna taximarknaden i Stockholmsområdet med ett stort fokus på traditionella taxibolag (multi-cab bolag) och moderna innovativa plattformsbaserade taxibolag (non-cab bolag). Huvudfokus är på Taxi Stockholm som är en ledande aktör i Stockholmsområdet samt Uber och Heetch. Vad kan traditionella taxibolag göra för att konkurrera med de nya taxiplattformarna som har ett stort kostnadsledarskap och vad kan plattformsföretagen göra för att lyckas konkurrera på taximarknaden och ta över marknadsandelar? Moderna non-cab bolag behöver satsa stort på att följa lagstiftning och regleringar i den marknaden de bedriver verksamhet och inte konkurrera på sina egna villkor, göra satsningar på bättre arbetsvillkor för anställda och följa miljökrav är också av prioritering. Traditionella taxibolag behöver satsa resurser på innovation för att hänga med i den tekniska utvecklingen av taximarknaden, pressa ner sina priser eller erbjuda kunna bättre tillgänglighet gentemot sina kunder i form av stora taxiflottor och satsningar gentemot företagskunder och statliga uppdrag ses som möjligheter för konkurrenskraft. Syftet med denna studie är att undersöka taximarknaden i Stockholm för att ta reda på hur de traditionella taxibolagen ska kunna hantera inflytandet från de nya, moderna och innovativa taxiaktörerna. Studien innefattar intervjuer, datainsamling och observationer hos Taxi Stockholm 15 00 00 AB och användning av sekundära källor för att få in information om de nya aktörerna och deras styrkor och svagheter. Dessutom läggs ett stort fokus på vetenskapliga artiklar och kurslitteratur. Studien är baserad på en fallstudie med inslag av explorativ forskning för att undersöka en case-studie om ett traditionellt taxibolag. Semistrukturerade intervjuer gjordes hos VD samt övriga ledningschefer för att kunna kartlägga hur deras bolag ligger till i förhållande mot de konkurrerande innovativa aktörerna samt de traditionella aktörerna. / The taxi market has recently gotten new competition from innovative companies that have managed to reduce the prices of cab transport so much that they are now a serious contender in the global market. Some of these new companies include Uber and Heetch which are now competing in the taxi market of Stockholm, Sweden. This upcoming thesis includes mapping of the new modern taxi market in the Stockholm region with a big focus on traditional cab companies (multi-cap enterprises) and modern innovative platform-based cap companies (non-cab enterprises). The focal point is on Taxi Stockholm 15 00 00 AB which is the leading competitor in Stockholm, with focus on Uber and Heetch as well. What can traditional cab companies do so that they can better compete with new platform-based cab companies which have big cost and pricing advantages and what can they do to become powerful competitors and subsequently gain market shares? Modern non-cab companies need to respect the laws and regulations of the markets that they compete in which differs depending on which country they operate in. They also need to improve the working conditions for their drivers and be more environmentally oriented. This will show that they take responsibility and are high calibre enterprises that take their societal responsibilities and duties seriously. Traditional cab companies and multi-cab companies need to invest resources and R&D into innovation, so that they can follow the technological development and the digitalization of the taxi market. Lowering their prices and cost is also important so that they can utilize better prices towards their customers, otherwise they would need to have many caps available to have big availability. Multi cap companies have good opportunities to utilize companies and big enterprises as their customers and government orders, this will in turn make them more competitive in the new era of Taxi businesses. The purpose of this comprehensive study is to research and compel the taxi market of Stockholm to discover and learn how the traditional multi-cap companies can handle the influence of the new innovative modern taxi companies. The study includes interviews, collection of data and observations of Taxi Stockholm 15 00 00 AB and the utilization of secondary sources to gain information about the new competitors and their strengths and weaknesses. A big part of secondary sources is also from scientific articles and course literature.   The study is based on a case study and some exploratory research methods in order to identify the mission and goal of this study. The interviews were done in a semi structured manner which was done with the CEO and the rest of the department executives, to be able to map their company in alignment with the rest of the competition in Stockholm including new innovative companies (non-cab) and traditional multi-cab companies.

Indagações quanto à possibilidade de a IA substituir o trabalho do homem ou à eventualidade de que a máquina possa vir a pensar como um ser humano aparecem quando se discorre a respeito da interação da máquina com a sociedade. Aparentemente, há consenso entre os especialistas sobre o fato de que a IA seja uma tecnologia importante na prática do Direito. O objetivo deste trabalho é apresentar tal tecnologia ao leitor, identificar seus principais impactos na profissão jurídica e mapear os desafios que aparecerão do conflito e da confusão gerados pelas mudanças tecnológicas. Como a discussão sobre o alcance da IA é recente, foi realizada uma revisão bibliográfica a respeito do tema. Para tanto, foi consultada a literatura especializada publicada por meio das mídias tradicionais durante os últimos dez anos no Brasil, nos Estados Unidos e na Europa. Para relatar a abrangência da tecnologia em questão, optou-se por pesquisar experiências de empresas brasileiras que estejam desenvolvendo ferramentas de IA para o mundo jurídico, bem como comentar experiências de escritórios de advocacia na discussão e implementação de atividades relacionadas com a IA. O trabalho de revisão bibliográfica foi complementado com a exposição de relatos de empresas que atuam no desenvolvimento de ferramentas de IA, nos setores público e privado, bem como de colaboradores de escritórios brasileiros que têm estudado formas de utilização dessas ferramentas. Este trabalho aponta para a importância de se acompanhar a utilização das ferramentas da IA na profissão jurídica. Tal tendência pode contribuir para a liberação do tempo do advogado, permitindo-lhe concentrar-se em funções estratégicas, e está alinhado com a demanda dos clientes por serviços a preços cada vez mais competitivos, representando um incentivo para que sejam encontradas formas alternativas de realização do trabalho dos advogados. A pesquisa referente ao desenvolvimento de tais ferramentas é fundamental e deve ser aprofundada. Faz-se necessário, também, discutir a grade de formação do advogado, com o objetivo de capacitar o aluno a atuar com conhecimentos ampliados que lhe permitam trabalhar como um agente multidisciplinar na indústria de serviços legais. / Recent achievements coming from Artificial Intelligence (AI) tools provoke increasing curiosity while generating some discomfort. Inquiries about the possibility of AI replacing human work or the possibility that the machine may think like a human appear when discussing the interaction of the machine with society. There seems to be consensus among scholars that AI is an important technology in law practice. The objective of this work is to present the technology to the reader, to identify the main impacts of AI in the legal profession, and to map the challenges that will arise from the conflict and the confusion generated by the technological changes. Since the discussion about the scope of AI is recent, a bibliographical review of the specialized literature, over the last 10 years, has been carried out on traditional media from Brazil, the United States and Europe. In order to report the scope of the AI, the experiences from both Brazilian companies that are developing AI tools for the legal world and from law firms in the discussion and implementation of activities related to AI have been researched. The bibliographical review work was complemented by the reports of companies that work in the development of AI tools both in the public and private sectors, as well as by the experience related by Brazilian legal firms who have studied ways of using these tools. This work points to the importance of accompanying the use of AI tools in the legal profession. Such a move can contribute to the lawyer's time release by allowing him to focus on strategic functions and is aligned with customer´s demand for services at increasingly competitive prices, representing an incentive to find alternative ways of performing the lawyers´ work. The research concerning the development of such tools is fundamental and should be deepened. It is necessary to discuss the lawyer´s training grid with the objective of enabling the student to act with expanded knowledge in order to enable him to work as a multidisciplinary agent in the legal services.

Evidências apontam para forte relação independente entre maus tratos na infância, comportamentos disruptivos e prejuízos em funções executivas. No entanto, ainda não é completamente compreendido como estes três fatores se relacionam entre si. Esta pesquisa avaliou a relação entre maus-tratos na infância e transtornos do comportamento disruptivo, testando desempenho em funções executivas como possível mediador e moderador desta relação. A presente pesquisa está inserida no estudo \"Coorte de escolares de alto risco para o desenvolvimento de psicopatologia e resiliência na infância e adolescência - projeto Prevenção\", projeto integrante do Instituto Nacional de Ciência e Tecnologia de Psiquiatria do Desenvolvimento para Infância e Adolescência (INCT-INPD), o qual incluiu 2500 crianças em idade escolar de São Paulo e Porto Alegre (Brasil). As crianças foram extensamente avaliadas com entrevistas diagnósticas, relatos de pais e da própria criança sobre maus tratos e com testes neuropsicológicos. Resultados indicam associação de maus tratos na infância e transtornos do comportamento disruptivo, porém não foi encontrada associação entre maus tratos e funções executivas. Crianças com transtornos do comportamento disruptivo apresentaram pior desempenho em teste específico para avaliação de flexibilidade cognitiva. Desempenho em funções executivas não agiu como mediador ou moderador da associação entre maus tratos e transtornos do comportamento disruptivo. Desta forma, os resultados indicam que a associação entre experiências de maus tratos e transtornos do comportamento disruptivo ocorre independentemente do desempenho em funções executivas. Futuros estudos longitudinais são fundamentais para confirmar estes resultados e elucidar os mecanismos cognitivos envolvidos nesta associação causal / Empirical evidences point to a strong independent relationship between maltreatment in childhood, disruptive behaviors and impairments in executive functions. However, how these three factors are interrelated it is not completed understood yet. This study evaluated the relationship between childhood maltreatment and disruptive behavior disorders, testing performance in executive functions as possible mediator and moderator factor in this relationship. This research is part of the study \"Cohort of high-risk students for the development of psychopathology and resilience in childhood and adolescence - Prevention Project\", a member project of the National Institute of Science and Developmental Psychiatry Technology for Children and Adolescents (INCT -INPD) in which is included 2,500 schoolchildren from São Paulo and Porto Alegre (Brazil). The children were evaluated with diagnostic interviews, reports of parents and children themselves about maltreatment and with neuropsychological tests, which included evaluation of inhibitory control, working memory, cognitive flexibility and planning. Results indicate association of childhood maltreatment and disruptive behavior disorder, but no association was found between maltreatment and executive functions. Children with Disruptive Behavior Disorders showed worse performance in specific task for assessment of cognitive flexibility. Performance in executive functions didn\'t work as a mediator or modifier variable in the association between childhood maltreatment and disruptive behavior disorder. Thus, the study results indicate that the association between experiences of maltreatment and disruptive behavior disorder occurs regardless of the performance in executive function in a community sample. Future longitudinal studies are essential to confirm these findings and elucidate the cognitive mechanisms involved on this causal association

O proposito deste estudo e avaliar o impacto psicologico da vivencia hospitalar de individuos que sofrem complicacoes pos-operatoria, partindo do pressuposto de que a intercorrencia agrava o quadro clinico com repercussoes na esfera psiquica destes pacientes. Teoricamente enfoca a evolucao do conceito de trauma na teoria freudiana, partindo do desamparo primordial (hilflosigkeit) ate a nova concepcao de angustia, levando em consideracao o fator economico, a nocao de a posteriori (nachträglichkeit) e a compulsao a repeticao. Com o intuito de ampliar a compreensao do fenomeno, o estudo percorre a etiologia do trauma para outros teoricos: Sandor Ferenczi, sobre o narcisismo da doenca; Donald W. Winnicott, que correlaciona o trauma a vivencia do fracasso do ambiente, a imprevisibilidade, ao excesso de tempo de exposicao a situacao desorganizadora, e a elevacao do nivel de dependencia. A constancia desta situacao leva ao que Maksud Khan nomeou de trauma cumulativo. A hipotese e a de que esta experiencia hospitalar pode promover um trauma psiquico, na medida em que o individuo se ve diante de uma situacao imprevisivel, que pode lhe causar transbordamento emocional pelo estado de desamparo, impotencia e risco da perda de sua integridade fisica -, que inibe uma elaboracao psiquica. Apos a alta hospitalar tais fatores podem, ainda, desencadear efeitos pos-traumaticos, acarretando-lhe, assim, uma dificuldade adaptativa. Para Moty Benyakar isto significa que o evento disruptivo pode promover um vivenciar traumatico dado a magnitude do impacto no psiquismo. Metodologicamente, para melhor compreensao do processo psiquico, faz-se um estudo longitudinal, de seis sujeitos, iniciando enquanto estes se encontram hospitalizados (situacao potencialmente traumatica), tres e seis meses apos a alta hospitalar. Na aplicacao do metodo qualitativo o estudo baseia-se na coleta de dados com entrevistas e na aplicacao reduzida da tecnica projetiva do TAT (Thematic Apperception Test). Pelo metodo quantitativo os pacientes sao submetidos a aplicacao da escala de avaliacao do transtorno de estresse pos-traumatico (CAPS Clinician Administred PTDS Scale). Esta pesquisa foi realizada em Hospital Escola de Universidade Publica, apos a aprovacao do Comite de Etica desta instituicao e do Comite de Etica para Seres Humanos do Instituto de Psicologia da Universidade de Sao Paulo. Atraves dos resultados obtidos na pesquisa pode-se constatar que ha uma relacao direta entre o evento e os seus efeitos no psiquismo. Pelo proprio carater disruptivo da instituicao hospitalar, dos encargos dos problemas de saude e do entorno (familiar, socioeconomico) o individuo vivencia uma vulnerabilidade fisica e psiquica. Contudo constatou-se que a dimensao da repercussao psiquica esta diretamente associada ao quadro clinico dos pesquisados, e ao tempo que ficam expostos a situacao potencialmente traumatica. Sendo este um fator fundamental na incidencia dos sintomas do Transtorno de Estresse Pos-traumatico. Com base neste estudo psicologico das complicacoes pos-operatorias, espera-se possibilitar aos profissionais de saude um novo olhar ao promover sua conscientizacao sobre problemas advindos desta experiencia, nao so aos individuos como, tambem, aos familiares, levantando a possibilidade de, se necessario, recorrerem a uma assistencia psicologica e/ou psiquiatrica / The objective of this study is to assess the psychological impact in subjects who stay in hospital after suffering from post-operative complications, on the assumption that the clinical picture gets worse causing troubles in the psychic area of these patients. Theoretically it focuses the evolution of the concept of trauma according to Freudian theory, since the primordial abandonment (hilflosigkeit) up to the new concept of distress, considering the economical situation, the concept of a posteriori (nachtraglichkeit) and the repetition compulsion. Aiming to offer a deeper understanding of the phenomenon, the study works with the etiology of trauma by other theorists: Sandor Ferenczi, about the narcissism of the disorder; Donald W. Winnicott, who relates the trauma to the experience of the environment failure, the unpredictability, the length of time facing a disordering situation, and the raising in dependence level. The constancy of this situation leads to what Maksud Khan called as cumulative trauma. The hypothesis is that in-hospital experience might provide a psychic trauma in so far as the subject has faced an unpredictable situation that might cause an overflow of emotions feeling abandoned, powerless and at the risk of losing physical integrity -, inhibiting a psychic elaboration. After having been discharged from hospital, such factors might also trigger post traumatic effects, implying into an adapting difficulty. According to Moty Benyakar, the disruptive event might provide a traumatic experience due to the great impact in the psychism. Methodologically for a better understanding of the psychic process, a longitudinal study has been made, with a number x of subjects, starting while they are in hospital (a potentially traumatic situation), from three to six months after they had been discharged from hospital. Applying the qualitative method the study has been based on the data collected through interviews and in the reduced application of the projective technique of TAT ( Thematic Apperception Test). Through the quantitative method the patients have been submitted to the application of the evaluation scale on the post-traumatic stress disorder (CAPS - Clinician Administered PTDS Scale). This research was carried out at the Hospital Escola da Universidade Publica, after the approval of the Comite de Etica ( Ethics Committee) of this institution and the Comite de Etica para Seres Humanos ( Ethics Committee for Human Beings) of the Instituto de Psicologia (Psychology Institute) of Universidade de Sao Paulo (USP). Through the results provided by the research, it was observed that there is a direct relation between the event and the effects in the psychism. For the own disruptive aspect in hospital, the burdens of health disorders and other surroundings ( familiar, socio- economic problems), the subject lives in a physical and psychic vulnerability. However it was pointed out that the dimension of the psychic repercussion is directly linked to the clinical picture of the six subjects who are studied, and the length of time that they have been exposed to the potentially traumatic situation. And this factor is extremely important in the incidence of the symptoms of the Post-Traumatic Stress Disorder. This psychological study of the post- traumatic surgery complications is meant to bring to health professionals much more awareness about the problems that come after this experience, not only for the subjects as well as to the relatives, who should be allowed to require, whenever necessary, some psychological and/or psychiatric treatment

Este trabalho enfoca o campo de atuação do marketing de serviços, setor cada vez mais representativo nas economias mundiais, em que a competitividade igualmente crescente demanda das empresas a capacidade de inovar e se diferenciar continuamente em prol da sobrevivência e crescimento. As características distintivas de marcas de serviços, sobretudo o caráter intangível da prestação, trazem para estas empresas o desafio da transformação dos serviços em benefícios concretos, buscando um posicionamento sólido junto aos consumidores e influenciando o processo de decisão de compra. Assim, é objetivo deste trabalho estudar como o posicionamento de marcas de serviços é gerido quando ocorre a introdução de uma inovação disruptiva, ou seja, quando a empresa decide pela introdução de uma tecnologia de ruptura, com uma proposição de valor consideravelmente diferente da tecnologia vigente. A metodologia adotada envolveu primeiramente a revisão de literatura nos temas de marketing de serviços, segmentação/posicionamento e aspectos da inovação disruptiva, buscando um entendimento da relação entre os construtos. De forma complementar, considerando-se a adequação com a questão de pesquisa, decidiu-se pela condução de um estudo de caso enfocando uma empresa do setor de serviços de telecomunicação móvel brasileiro, a Vivo S/A. A decisão pelo estudo de caso único foi motivada pelo caráter peculiar da situação estudada, representada pela introdução da tecnologia GSM pela empresa no período compreendido entre os anos 2006 e 2007, em caráter disruptivo. Estudou-se a forma como a empresa procedeu no tocante aos processos de segmentação, posicionamento e gestão do composto de marketing frente a este evento. Os resultados apontam para uma influência significativa da mudança tecnológica no posicionamento da marca, com maior impacto nos fatores relacionados a produto, promoção e pessoas, do composto de marketing de serviços. A pesquisa também revelou o poder de tecnologias emergentes em transformar as competências internas de uma empresa, muito além da tecnologia em si. Por fim, os resultados mostram como a empresa conseguiu resultados positivos nas dimensões de negócios e de marca, revertendo uma situação competitiva desfavorável, identificada no contexto que se pôde construir para o caso. / The following dissertation will address the theme of services marketing, a sector that has been increasingly representative in global economies, where competitiveness is constantly growing and demands that companies have the ability to continually innovate and differentiate in favor of their own survival and growth. The distinctive characteristics of service brands, especially the intangible characteristic, bring to these companies the challenge of transforming services into concrete benefits, seeking a solid position among consumers and influencing the purchase decision process. Thus, the objective of this project is to study how the positioning of services brands are managed when there\'s introduction of a disruptive innovation, ie, when the company decides to introduce a disruptive technology, with a value proposition considerably different from the current technology. The adopted methodology involved primarily a literature review in the areas of services marketing, segmentation / positioning and aspects of disruptive innovation, seeking to understand the relationship between the concepts. In a complementary way, considering the suitability to the research question, it was decided to conduct a case study focused on a mobile telecommunications company in Brazil, Vivo S/A. The decision for a single case study was motivated by the peculiar character of the studied situation, represented by the introduction of GSM technology by the company in the period between 2006 and 2007 in a disruptive character. The project sought to understand how the company proceeded regarding the processes of segmentation, positioning and management of the marketing mix, considering this event. The results point to a significant influence of technological change in brand positioning, with the greatest impact on factors related to product, promotion and people of the services marketing mix. The research also revealed the power of emerging technologies to transform the internal competencies of a company, beyond the technology itself. Finally, the results show how the company achieved positive results in the dimensions of business and brand, reversing a competitive disadvantage, identified in the context that could build into the case.

Marine environments are under constant pressure from anthropogenic pollution. Chemical pollutants are introduced into the aquatic environment through waste disposal, sewage, land runoff and environmental exploitation (harbours, fisheries, tourism) leading to disastrous effects on the marine wildlife. Developmental malformations, reproduction failure including sex changes and high death rates are commonly observed in aquatic animal populations around the world. Unfortunately, the underlying molecular mechanisms of these pollution effects, in particular for marine invertebrate species, are often unknown. One proposed mechanism through which environmental pollution affects wildlife, is the disruption of nuclear receptors (NRs), ligand-binding transcription factors in animals. Environmental pollutants can directly interact with nuclear receptors, inducing incorrect signals for gene expression and subsequently disrupt developmental and physiological processes. Elucidation of the exact mechanism in invertebrates, however, is sparse due to limited understanding of invertebrate endocrinology and molecular regulatory mechanisms. Here, I have investigated the presence, expression and function of NRs in the Pacific oyster, Crassostrea gigas, and explored their interrelation with known environmental pollutants. Using a suite of molecular techniques and bioinformatics tools I demonstrate that the Pacific oyster possesses a large variety of NR homologs (43 NRs), which display individual expression profiles during embryo/larval development and supposedly fulfil distinct functions in developmental and physiological processes. Functional studies on a small subset of oyster NRs provided evidence for their ability to regulate gene expression, including interactions with DNA, other NRs or small molecules (ligand-binding). Oyster receptors also show a high likeliness to be disrupted by environmental pollutants. Computational docking showed that the retinoid X receptor ortholog, CgRXR, is able to bind and be activated by 9-cis retinoic acid and by the well-known environmental contaminant tributyltin. A potential interaction between tributyltin and the peroxisome proliferator-activated receptor ortholog CgPPAR has also been found. In addition, exposure of oyster embryos to retinoic acids and tributyltin resulted in shell deformations and developmental failure. In contrast, computer modelling of another putative target for pollutants, the retinoic acid receptor ortholog CgRAR, did not indicate interactions with common retinoic acids, supporting a recently developed theory of loss of retinoid binding in molluscan RARs. Sequence analyses revealed six residues in the receptor sequence, which prevent the successful interaction with retinoid ligands. In conclusion, this investigative work aids the understanding of fundamental processes in invertebrates, such as gene expression and endocrinology, as well as further understanding and prediction of effects of environmental pollutants on marine invertebrates.

Abstract Attention deficit hyperactivity disorder (ADHD) and disruptive behavior disorder (DBD) are two very common and co-occurring psychiatric disorders among children and adolescents. They are among the leading reasons for clinical referrals to child and adolescent mental health facilities worldwide and have many unfavorable consequences with a high cost to society. In this thesis, the potential early risk factors associated with ADHD and/or DBD were examined, the current well-being of the adolescent with ADHD and/or DBD was evaluated and the later education and the psychiatric morbidity of the adolescent were researched. The study population in this thesis is based on a subsample of the Northern Finland Birth Cohort 1986 (NFBC 1986) containing 457 study subjects, of which 91 (19.9%) were diagnosed with ADHD, 44 (9.6%) with DBD, 72 (15.6%) with comorbid ADHD and DBD and 250 (54.7%) with neither of these disorders. Confirmatory factor analysis, Kaplan-Meier survival analysis, Kruskal-Wallis one-way analysis of variance and several regression analyses were carried out in the study. This thesis contains four original publications. The results in the first publication indicated that there are different risk factors in childhood associating with different behavioral problems in adolescence. The differences between behavioral problems were also visible in the results of the second publication, where those adolescents who were diagnosed with both ADHD and DBD had more severe conduct disorder symptoms and had increased risks for many psychiatric disorders. The results from the third publication suggested that those adolescents who were diagnosed with both ADHD and DBD fared worse in school at the end of ninth grade and were later less likely to achieve higher than basic education. Finally, the fourth publication showed that the adolescents diagnosed with DBD (both with and without ADHD) seemed to have an increased risk for admittance to the psychiatric inpatient hospital. This thesis underlines the differences between children and adolescents diagnosed with ADHD and/or DBD and emphasizes the role of comorbidity between these disorders as an indicator of poorer outcomes later in life. / Tiivistelmä Tarkkaavaisuus- ja ylivilkkaushäiriö (attention deficit hyperactivity disorder, ADHD) sekä käytös- ja uhmakkuushäiriöt (disruptive behavior disorder, DBD) ovat hyvin yleisiä – ja usein yhtä aikaa ilmeneviä – lasten ja nuorten psyykkisiä häiriöitä. Nämä häiriöt ovat hyvin usein syynä lasten ja nuorten psykiatristen terveyspalveluiden käyttöön. Niillä on myös todettu olevan useita epätoivottuja seurauksia, joiden hoitaminen puolestaan nostaa yhteiskunnan kuluja. Tämä väitöskirjatyö tutkii mahdollisia varhaisia riskitekijöitä, jotka assosioituivat ADHD- ja/tai DBD-häiriöiden kanssa, arvioi näillä häiriöillä diagnosoitujen nuorten sen hetkistä hyvinvointia ja tutkii näiden nuorten kouluttautumista sekä muuta psykiatrista sairastavuutta. Tutkimusaineisto koostuu Pohjois-Suomen syntymäkohortti 1986 (Northern Finland Birth Cohort 1986, NFBC 1986) -aineiston osaotoksesta, johon kuuluu 457 henkilöä. Osaotoksesta 91:llä (19,9 %) oli diagnosoitu ADHD, 44:llä (9,6 %) DBD ja 72:lla (15,6 %) komorbidi ADHD ja DBD. 250 henkilöllä (54,7 %) osaotoksesta ei ollut diagnosoitu kumpaakaan diagnoosia. Aineiston analysoinnissa käytettiin konfirmatorista faktorianalyysiä, Kaplan-Meierin elossaolomenetelmää, Kruskal-Wallisin yksisuuntaista varianssianalyysiä ja useita regressioanalyysejä. Tämä väitöskirja koostuu neljästä osajulkaisusta. Ensimmäisen osajulkaisun tulokset osoittivat, että eri riskitekijät lapsuudessa assosioituivat eri käytösongelmiin nuoruudessa. Eri käytösongelmien eroavaisuudet olivat myös nähtävillä toisessa osajulkaisussa: niillä nuorilla, joilla oli diagnosoitu komorbidi ADHD ja DBD, todettiin olevan vakavampia käytöshäiriöiden oireita sekä kohonnut riski useisiin muihin psykiatrisiin sairauksiin. Kolmannen osajulkaisun tulokset viittasivat näiden nuorien, jotka oli diagnosoitu komorbidillä ADHD:lla ja DBD:llä, pärjäävän huonommin koulussa ja valmistuvan muita todennäköisemmin vain peruskoulusta. Lopuksi neljännessä osajulkaisussa todettiin, että DBD diagnoosin nuorena saaneilla (riippumatta ADHD diagnoosista) näytti olevan kohonnut riski psykiatriseen osastohoitoon joutumiselle. Tämä väitöskirjatyö alleviivaa tarkkaavaisuus- ja ylivilkkaushäiriöllä sekä käytös- ja uhmakkuushäiriöillä diagnosoitujen lasten ja nuorten eroavaisuuksia ja korostaa kyseisten häiriöiden komorbidin ilmenemisen roolia huonon lopputuloksen ennustetekijänä myöhemmin nuoren elämässä.

Abstract The objective of this thesis was to obtain new information about mechanisms of thermomechanical pulp refining in the inner area of a refiner disc gap by studying inter-fibre refining and by calculating the distribution of energy consumption in the refiner disc gap. The energy consumption of thermomechanical pulping process is very high although theoretically a small amount of energy is needed to create new fibre surfaces. Mechanisms of refining have been widely studied in order to understand the high energy consumption of the process, however, phenomena in the inner area of disc gap has had less attention. It is likely that this important position is causing high energy consumption due to the high residence time of pulp located there. The power distribution as a function of the refiner disc gap was calculated in this work. The calculation was based on mass and energy balances, as well as temperature and consistency profiles determined by mill trials. The power distribution was found to be dependent on segment geometry and the refining stage. However, in the first stage refiner with standard refiner segments, a notable amount of power was consumed in the inner area of the disc gap. Fibre-to-fibre refining is likely to be the most important mechanism in the inner area of disc gap from the point of view of energy consumption. In this work the inter-fibre refining was studied using equipment for shear and compression. Fibre-to-fibre refining was found to be an effective way to refine fibres from coarse pulp to separated, fibrillated and peeled fibres if frictional forces inside the compressed pulp were high enough. It was proposed that high energy of today’s thermomechanical pulping process could derive from too low frictional forces that heated pulp and evaporated water without any changes in fibre structure. The method to calculate power distribution and results of fibre-to-fibre refining experiments may give ideas for developing today’s thermomechanical pulp refiners’ or for developing totally new energy saving mechanical pulping processes.
