Estudos de expressão gênica geralmente envolvem a realização de processos de análise integrados para a obtenção de respostas biológicas de interesse. A realização destes processos frequentemente requer o uso combinado de uma série de ferramentas de software. No entanto, o processo de integração manual de ferramentas pode ser demorado e propenso a erros devido ao crescente número de ferramentas e formatos de dados disponíveis no domínio. De modo a automatizar o processo de integração, algumas abordagens têm sido propostas tanto para a adaptação das ferramentas de análise existentes como serviços web semânticos, quanto para o desenvolvimento de ambientes de suporte à integração (composição) de serviços web semânticos. Embora estas abordagens representem avanços, nenhuma solução adequada para o desenvolvimento e composição de serviços foi especificamente definida para o domínio de genômica funcional. Neste contexto, o principal objetivo deste projeto foi investigar uma solução completa para o desenvolvimento e composição de serviços web semânticos para a análise de expressão gênica. Como parte da solução proposta, definimos uma metodologia integrada para a implementação de serviços web semânticos criados a partir de ferramentas de software existentes e para a anotação semântica destes serviços. Nossa metodologia fornece diretrizes concretas para o desenvolvimento sistemático de serviços, considerando também os principais aspectos técnicos associados ao processo de desenvolvimento. Esta metodologia foi aplicada a um conjunto representativo de serviços que fornecem suporte às principais atividades de análise realizadas em diferentes tipos de dados de expressão gênica. De forma complementar, definimos uma solução completa para a composição semântica de serviços no domínio de análise de expressão gênica. A solução proposta foi implementada em uma plataforma de suporte semi-automático à composição de serviços web semânticos, chamada SemanticSCo. Esta plataforma fornece suporte flexível a todas as atividades envolvidas no processo de composição de serviços, incluindo a criação, publicação, requisição, descoberta, seleção, composição e execução de serviços. Além disto, a plataforma SemanticSCo foi projetada para prover suporte adequado a diferentes tipos de usuários, incluindo biologistas e bioinformatas. Neste sentido, a plataforma fornece aos usuários um alto nível de abstração para a definição de seus processos de análise, permitindo que os mesmos se concentrem mais nas questões de pesquisa biológicas do que nos aspectos subjacentes do processo de composição. Adicionalmente, a plataforma SemanticSCo suporta a definição e incorporação não apenas de serviços simples, definidos em termos de uma única operação, mas também de serviços complexos, definidos em termos de um conjunto de condições que restringem a ordem de invocação de suas operações. Finalmente, de modo a avaliar a plataforma de suporte desenvolvida, definimos diferentes cenários de composição para a análise (integrada) de dados de expressão gênica. O uso da plataforma SemanticSCo facilitou a definição destes cenários, permitindo assim a reprodução dos resultados obtidos a partir de diferentes estudos de expressão gênica previamente documentados na literatura / Gene expression studies usually involve the creation of integrated analysis processes for obtaining responses for a biological question. The creation of such processes often require the combined use of a number of software tools. However, the manual integration of tools can be cumbersome and error prone due to the increasing number of tools and data formats available in the domain. In order to automate the integration process, some approaches have been proposed for the adaptation of existing analysis tools as semantic web services as well as for the development of software environments to support the integration (composition) of semantic web services. Although these approaches present advances, to the best of our knowledge, no suitable solution has been proposed for the development and composition of web services in the functional genomics domain. In this context, this project aimed at investigating a complete solution for the development and composition of semantic web services to support gene expression analysis. As part of the proposed solution, we have defined an integrated methodology for the implementation of semantic web services created from existing software tools and the semantic annotation of such services. Our methodology provides concrete guidelines for the systematic development of services, also taking into account the main technical aspects associated with the development process. This methodology has been applied in the development of a representative set of services that support the main analysis activities performed on different types of gene expression data. Complementary to our methodology, we have defined a complete solution for the semantic composition of web services in the gene expression analysis domain. The proposed solution has been implemented in a software platform to support the semi-automatic composition of semantic web services, named SemanticSCo. This platform provides flexible support to all activities involved in the service composition process including service creation, publication, request, discovery, selection, composition and execution. Additionally, the SemanticSCo platform has been designed to support different types of users, including biologists and bioinformaticians. In this sense, the platform provides users with a high level of abstraction in the definition of their analysis processes, thus allowing them to focus more on biological research issues rather than on underlying details of the composition process. In addition, the SemanticSCo platform supports not only the definition and incorporation of (simple) services defined in terms of a single operation, but also (complex) services defined in terms of a set of conditions that constrain the order in which service operations should be invoked. Finally, in order to evaluate the developed support platform, we have defined a number of composition scenarios for the (integrated) analysis of gene expression data. The use of the SemanticSCo platform has facilitated the definition of these scenarios, thus allowing the reproduction of the results obtained from different gene expression studies previously documented in the literature.

No entanto, sua investigação empírica nas organizações tem sido lenta em função da escassez de escalas e itens de medição confiáveis e válidos. Recentemente, um constructo multidimensional denominado de competência em NSD foi proposto para refletir a capacidade da organização de utilizar recursos e rotinas, usualmente em combinação, a fim de atingir um determinado resultado no lançamento de um novo serviço. O constructo foi operacionalizado através de cinco escalas complementares entre si (foco no processo de NSD, acuidade de mercado, estratégia de NSD, cultura de NSD e experiência em TI) e validada em uma amostra de bancos de varejo americanos. A fim de analisar a validade externa da nova escala, esse estudo utilizou uma amostra oriunda de uma empresa brasileira prestadora de serviços de telecomuni / The topic of NSD (New Service Development) has received a lot of attention in the past years, especially given its important competitive necessity in many service industries. However, NSD empirical investigations have been hindered by the lack of sound measurement items and scales. Recently, a second-order multidimensional construct called NSD competence has been proposed to reflect an organization´s expertise in deploying resources and routines, usually in combination, to achieve a desired new service outcome. The construct was operationalized through five complementary multi-item scales (NSD process focus, market acuity, NSD strategy, NSD culture and information technology experience) that were validated in a sample of American retail banks. In order to assess the external validity of the NSD competence construct in a different cultural setting, a sample obtained from key informants of a specific Brazilian telecommunication service provider was used. The results showed a partially satisfactory construct

To understand the impact of this program, we chose as our case studies three teachers in this process of in-service development program of a private school in São Paulo city. We tried capture the subjective directions produced by these teachers on their teaching practice and then to point out awareness markers in these developing teachers. The Theory of the Subjectivity, by Fernando González Rey (2001, 2002, 2003, 2004, 2004a, 2005), together with the contributions by Aguiar (1997, 2001), Aguiar and Ozella (2006) helped us in this analysis which allowed us to understand the subjective directions expressed by the teachers. As reference for the development program we based our research on authors such as Placco (2000, 2000a, 2002, 2006, 2007, 2008), Almeida (2000, 2007), Gatti (1972, 2003), Nóvoa (1992), Marcelo Garci'a (1999, 2007), Mizukami et al (2003), Imbernón (2004) and Zeichner (1993, 1993a), amongst others. The methodology used is inserted in the paradigm of the qualitative research, having interviews as main source of information, besides some other tools such as short essays, choosing paintings by some known painters and observation. In the development process of the analysis, markers and meaning groups emerged making possible the acquisition of directions, from which we made the awareness markers of the teacher inserted in this program. These awareness markers are the subjective directions produced by the teachers in the sense of value to their teaching practice; emotions such as involvement, satisfaction, willingness; search for knowledge necessary for teaching; the value of spaces for the in-service development program; the confrontation and relationship between the coordinator and the teacher which should be based on respect, cooperation, focus on the professional. Getting to know Indicators of teachers awareness movement in the process of in-service continued education helps the coordinator/trainer to be more appropriately and efficiently supportive during the teachers development / O presente trabalho pretende ser uma contribuição para a Formação Continuada em Serviço, entendida como um espaço prioritário de formação docente na escola em que os professores ministram as aulas. Para a compreensão do impacto dessa Formação Continuada, escolhemos como objeto de estudo três professores inseridos em um processo de formação continuada em serviço de uma escola de ensino particular da cidade de São Paulo. Buscamos apreender os sentidos subjetivos engendrados por esses professores sobre sua docência e, a partir deles, apontar indicadores de movimentos de conscientização nesses professores em processo de formação continuada em serviço. Auxiliou-nos nessa análise a Teoria da Subjetividade, de Fernando González Rey (2001, 2002, 2003, 2004, 2004a, 2005) que, juntamente com as contribuições de Aguiar (1997, 2001), Aguiar e Ozella (2006), permitiu compreender os sentidos subjetivos expressos pelos professores. Como referência para a formação continuada, apoiamo-nos em autores como Placco (2000, 2000a, 2002, 2006, 2007, 2008), Almeida (2000, 2007), Gatti (1972, 2003), Nóvoa (1992), Marcelo Garcia (1999, 2007), Mizukami et al (2003), Imbernón (2004) e Zeichner (1993, 1993a), dentre outros. O método utilizado insere-se no paradigma da pesquisa qualitativa, tendo como procedimento para coleta das informações, prioritariamente, entrevistas recorrentes, além de outros instrumentos, como redação, escolha de quadros de pintores e observação. No processo de desenvolvimento da análise, emergiram indicadores e núcleos de significação que possibilitaram a apreensão de sentidos, a partir dos quais elaboramos os indicadores de movimentos de conscientização dos professores inseridos nesse processo de formação continuada em serviço. São indicadores de movimentos de conscientização: os sentidos subjetivos engendrados pelos professores na direção da valorização da docência; emoções como: envolvimento, alegria, disposição; busca pelos saberes necessários à docência; a valorização dos espaços de formação continuada em serviço; o confronto com os pares e a relação coordenador-professor baseada no respeito, na parceria, na valorização do profissional. Conhecer indicadores de movimentos de conscientização do professor em formação continuada em serviço favorece ao coordenador/formador interferências mais adequadas, eficientes e eficazes nos processos de formação

Den demografiska utvecklingen i Sverige går mot en befolkningssammansättning med allt högre medelålder. Prognosen tyder på att nästan var fjärde svensk år 2025 kommer vara 65 år eller äldre. Många av dessa individer har en aktiv, frisk och relativt lång ålderdom framför sig. Studier har visat att morgondagens seniorer är en relativt välbeställd grupp med höga krav och stora förväntningar på ålderdomen och det framtida boendet. Allt detta innebär en utmaning för samhället där nödvändiga prioriteringar kan leda till att individen måste ta ett större ansvar och eget initiativ för boende och omvårdnadstjänster gentemot tidigare. I avhandlingen (”studien”) har seniorboendekonceptet med integrerade service-, vård- och omsorgstjänster studerats särskilt. Seniorboenden är ett marknadssegment med kraftig tillväxt under 2000-talet. Antalet seniorbostäder i Sverige har ökat från ca 10 000 år 2000 till ca 28 000 år 2007. Det som karaktäriserar konceptet är att boendet och de anslutande tjänsterna har anpassats och särskilt utformats för ett liv i åldrande. Studien rapporteras i form av en monografi bestående av två olika delstudier. Forskningsfrågan som varit vägledande för den första delstudien är ”Vad skapar en stark marknadsposition för en aktör på seniorbostadsmarknaden med integrerad service, vård och omsorg?”. Forskningsfrågan i den andra delstudien är ”Vilka produktionsstrategier och styrsystem går att identifiera hos några av de mest framgångsrika konceptbyggarna?”. Den andra delstudien utgår från den första delstudiens resultat. Forskningen, som har bedrivits som en explorativ fältstudie, har pågått under perioden 2002-2008. Mätinstrumentet har bestått av fasta intervjufrågor med öppna svarsalternativ. De underliggande intervjuerna har tillsammans med sekundärdata presenterats i ett antal fallbeskrivningar. I studien har ett antal framgångsrika, såväl svenska som nordamerikanska, aktörer medverkat. Den första delstudien har analyserats utifrån en föreställningsram som byggts upp kring begreppen omgivning, strategi, resurs, tjänstekoncept och konkurrenskraft. Resultaten har formulerats i ett antal strategiska vägval vilka sammanfattats i begreppen differentiering, fokus, integration, samverkan, kontroll, verksamhetsutveckling, kärnkompetens och resurser. Det har kunnat påvisas att framgångsrika aktörer följer den differentieringsstrategi om Porter (1980) definierat. Vidare har en affärsstrategisk typologi över aktörer på seniorboendemarknaden formulerats. Den första delstudiens slutsatser har formulerats i fyra strategiska idealtyper: förvaltare, konceptbyggare, entreprenörer och idealister. Utgångspunkten i den andra delstudien, som bl.a. hämtats i Nilssons och Rapps (2005) teoretiska ramverk, har varit idealtypen konceptbyggare. Med vissa kompletteringar har detta ramverk nyttjats och utvecklats för att beskriva och analysera orsakssambanden kring strategisk kongruens och integrerad styrning. Kompletteringar och justeringar har skett för att även omfatta strategier och styrsystem för bygg- och tjänsteproduktion. Föreställningsramen har, utifrån den erfarenhet som erhållits vid analysen av insamlad data, justerats. Justeringen har bestått i klassificeringsdimensionerna IT, organisationskultur och värdegrund. I studien, som bl.a. består av fallbeskrivning och analys av konceptbyggare, har framkommit att de konceptbyggare som nått framgång också har lyckats uppnå strategisk kongruens och integrerad styrning. Studien har bl.a. kunnat påvisa vad betydelsen av boendets fysiska planering innebär för möjligheten att bedriva tjänsteproduktion. Studien har bl.a. visat att nordamerikanska konceptbyggare har en hög grad av samstämmighet mellan strategi och styrsystem. Samstämmigheten kan sammanfattas i marknadskännedom, tydlig verksamhetsidé, branscherfarenhet, insikt om skalfördelar via klustring, organisatorisk småskalighet, känsla för värdeskapande, målinriktning, långtgående befogenheter och delegerat ansvar, värdestyrd verksamhet och en väl utvecklad organisationskultur. De nordamerikanska konceptbyggarna har definierat sina verksamheter som hotellverksamhet för seniorer vilket innebär att de boende blivit kunder och de äldre i allmänhet betraktas som en tillgång. / The demographic trend in Sweden features a population with a rising average age. According to forecasts, nearly one Swede out of four will be 65 or older by the year 2025. Many individuals in this category of older persons, or seniors, can look forward to an active, healthy and relatively long old age. Studies have shown that tomorrow’s seniors and retirees will be relatively well off as social groups. In addition, attitude and generation surveys have indicated that these groups have high demands and expectations for their old age, future housing and related services. Society will thus face a considerable challenge, which includes maintaining a basic commitment to continue guaranteeing the standard of quality in housing and services for the elderly that is presently taken for granted. Necessary societal priorities, however, may require individuals to take more initiative and assume greater financial responsibility than before in some of these areas. In the 2000’s a new market segment has been established and shown vigorous growth. That segment is the senior housing market, where various housing concepts are offered to the target group, seniors, or persons aged 55+. The number of senior housing units in Sweden has soared in the last few years, from about 10 000 in 2000 to some 28 000 in 2007. In this study, the concept of senior housing, with features of integrated service and care, has been of special interest. What characterizes this housing concept is that housing and related services have been adapted and specially designed for living as an aging individual. This dissertation (”the survey”) is reported in the form of a monograph consisting of two separate studies. The research question that has guided the first study is, “What creates a strong market position for a player on the senior-housing market with integrated service, health care and other forms of service and care?” The research question for the second study is, “What production strategies and control systems can be identified for some of the most successful concept-builders?” The two studies are related in that the latter is based on the results of the former. The studies were conducted over a period from 2002 to 2008. The research was done as an exploratory field study. The field-study approach has given priority to breadth and inclusion of many aspects. The instrument of measurement has consisted of set interview questions with open-ended alternative responses. The underlying interviews, together with secondary data, have been presented as a number of case studies. In the survey, a number of successful players have been selected on the basis of the criteria considered typical of successful actors on the senior housing market. Both Swedish and North American organizations have participated in the survey. The empirical material of the survey has been analyzed on the basis of the theoretical conceptual frameworks developed for the two respective studies. The first study has been analyzed with a framework based on the concepts of environment, strategy, resources, service and competitiveness. The results have been formulated in a number of strategic choices that are summarized in the concepts of differentiation, focus, integration, collaboration, control, business development, core competence and resources. In this connection, it has been possible to show that actors who operate a successful business follow largely what Porter (1980) has defined as a strategy of differentiation. Moreover, a business-strategy typology of actors on the senior housing market has also been constructed. Also, the tentative conclusions of the first study have been formulated in four strategic ideal types: administrators, concept-builders, entrepreneurs and idealists. The point of departure for the second study has been the ideal type referred to as the concept-builder. The conceptual framework has therefore been developed further, based in part on the theoretical framework of Nilsson and Rapp (2005). With certain additions, these foundations have been used to construct a detailed theoretical framework for the study. The conceptual framework has been designed to describe and analyze the causal relationships relating to strategic congruence and integrated control. In this regard, additions and adjustments have been made to include strategies and control systems for the construction of buildings and the production of services. The results of the second study include a case description and an analysis of successful concept-builders. One reason for their success is assumed to be their ability to achieve strategic congruence and integrated control. In light of the findings from the analysis of the data, the conceptual framework has been somewhat modified. This adjustment has consisted in classification along the dimensions of IT, organizational culture and fundamental values. In this connection it has been possible to demonstrate the importance of the physical planning of housing for the production of services. Emphasis has been placed on designing the physical facility and housing right from the beginning so as to facilitate the service-producing operation in a later stage of the life cycle. One finding of the survey is that with North American concept-builders there is a high degree of consistency between strategies and control systems. The factors underlying this consistency can be summarized as market knowledge, industry experience, understanding the economies of scale attainable through clustering, organization on a small scale, a clear concept of business, a sense of value creation, a focus on objectives, farreaching delegation of authority and responsibility to the operating level, skilled management, value-oriented operations and a well-developed organizational culture. Through the survey, a number of customer-controlled operations have been illustrated in the case studies. It is apparent that compared to the past, there has been a shift in industry attitude in North America, creating a situation that differs from Swedish conditions in some respects. The North American concept-builders have defined their businesses as hotel operations for seniors. This has automatically shifted the focus toward one where residents have become customers and older people in general are regarded as assets.

Ur ett företagsekonomiskt perspektiv finns det ett stort intresse av att utveckla innovativa tjänster då forskning visar att det skapar hållbara konkurrensfördelar. Fastighetsföretag arbetar med tjänsteutveckling för att fylla sina fastigheter och arbetar tätt ihop med sina kunder där efterfrågan styr utvecklingsprocessen. Föreliggande studie testar Wang & Tsais (2012) tjänsteutvecklingsmodell där metoderna tjänstekartläggning, ‘service blueprint’ och ‘axiomatic design’ utgör verktyg för fastighetsföretag. Med dessa metoder ska företaget identifiera kundernas behov och leverera en ny tjänst som uppfyller både interna och externa krav. Genom innovativ tjänsteutvecklingsprocess minskar på så sätt gapet mellan kunders förväntningar om vad företaget kan erbjuda för tjänster och fastighetsbolags uppfattningar om vilket behov kunderna har. Med denna utgångspunkt utformades studiens forskningsfrågor; -     Vilka tjänster kan fastighetsföretagen erbjuda för att matcha den efterfrågan som ställs av nyetablerade entreprenörer? -          Hur kan fastighetsföretag genom ’service blueprinting’, i ett nära samarbete med kunden, skapa innovativa tjänster med en långsiktig plan för lokalkontrakt? -          Hur arbetar fastighetsföretag med ’axiomatic design methodology’, för att konstruera tjänster som efterfrågas av nyetablerade entreprenörer, och på så sätt skapa hållbara konkurrensfördelar? / From a business perspective, there is a considerable interest in developing innovative services, as research shows that it creates sustainable competitive advantage. Real estate companies are working with service development to fill their properties and work closely with their customers where demand determines the development process. The present study tests the Wang & Tsai (2012) service development model where the methods service mapping, service blueprint and axiomatic design provides tools for real estate companies. With these methods, the company shall identify customer needs and deliver a new service that meets both internal and external requirements. Through innovative service development process, the gap between customers’ expectations of what services the company can offer and the real estate companies’ perceptions of what needs the customers have decreases. On this basis, the research questions of the study were designed; -          What services can property companies offer to match the demand made by newly established entrepreneurs? -          How can the real estate company through service blueprinting, in a close cooperation with the customer, create innovative service with a long-term plan for local contracts? -          How do real estate companies work with axiomatic design methodology, to construct the services demanded by newly established entrepreneurs, and thus create sustainable competitive advantage?

A series of extension, such as OCL, XMI, ASL, MOF, UML profiles, and different proposed formal semantics, to the language and to its application scope have fedoff each other in synergy. While these extensions constitute a sound starting point to make UML the pivotal element for the Model-Driven Engineering (MDE) and Semantic Web (SW) visions, many other building blocks are still missing, including: (1) Complete formal semantics for UML and OCL; (2) UML inference engine based on such semantics to support model checking and intelligent agent reasoning with UML semantic web ontologies; (3) UML model compilers to fully automate both structural and behavioral code generation from detailed UML/OCL models. In this thesis, we present the MODELOG framework based on a single proposal to address these three issues: it consists of an automatic mapping from fully refined UML/OCL models to the object-oriented logic programs in the Flora-2, an executable and Turing-complete language with a well-defined formal semantics. We developed the MODELOG mapping as model transformations. As source for these transformations, we reused the UML2 and OCL2 metamodels provided by OMG and as target we developed a Flora metamodel. As we experimented and compared two language to implement the transformation: the dedicated transformation language ATL based on OCL, and Flora itself viewed as a model transformation language. As validating case study for MODELOG, we developed the Triangram robotic assembly puzzle. It is an example of planning tasks often executed by agents and it requires a complex class hierarchy together with complex structural and behavioral constraints. The Flora PSM of this puzzle was entirely automatically generated from its UML/OCL model by applying the MODELOG transformations. The main originality of this thesis is twofold. First, it simultaneously tackles various gaps in UML for its new extended role: formal specification language, MDE, semantic web services and agent engineering, Second, it does so without putting forward any new language but only by reusing a theoretically consolidated and efficiently implemented one. In contrast, previous proposals tend be limited to one or two such applications while often proposing new languages. The thesis makes contributions to various fields: For MDE, it shows the feasibility of completely automated full structural and behavioral executable code generation from a UML/OCL PIM, on a non-trivial, complex case study involving automated reasoning; For agile development, it reconcile that the robustness of formal methods with the early testing of fast prototyping, since MODELOG not only generates executable code, but also model checking code from UML/OCL models. For UML and OCL, it provides a fully integrated denotational formal semantics in Transaction Frame Logic on which Flora is based; For logic programming, it provides compositional metamodels of all the languages integrated in the Flora platform that clarify their relations and make them available as source or target language for a variety of MDE tasks such as model checking and fast prototyping; it also provides a way to develop logic programs using the consolidated full-life cycle object-oriented software engineering processes; For agent engineering, it shows how to get combine the complementary strengths of the object-oriented and logic paradigms, the two mostly widely reused in agent-oriented methods; For the semantic web service development, its introduced a highly automated MDE approach allowing to model them visually with UML-based industrial strengths method and CASE tools, and automatically generate their specification in the W3C standard SWSL, which is a XML-enabled variant of Flora

Dentre esses recursos estão os serviços científicos, usados para processar dados em determinadas tarefas de um processo de experimentação científica. Desenvolvedores especializados criam e mantêm esses serviços científicos. O sucesso de uma experimentação científica depende da correta execução de seu processo. Como os serviços científicos são utilizados em tarefas dos processos, suas falhas comprometem toda a experimentação. Por isso, é importante que os serviços estejam funcionando corretamente. Neste contexto, é necessário apoiar o desenvolvedor de serviços científicos para que ele possa desenvolver serviços com o máximo de eficiência possível. Diante disso, o objetivo deste trabalho é apresentar recursos que buscam apoiar o desenvolvimento de serviços científicos em uma plataforma de ecossistema de software científico. Esses recursos são associados a um processo de desenvolvimento de serviços que mapeia as atividades dos desenvolvedores e cientistas durante o desenvolvimento de serviços. Apresenta uma interface para análise contextual dos serviços, oferecendo elementos de visualização associados a informações contextuais. Além disso, utiliza a análise de redes sociais científicas para auxiliar na seleção de cientistas mais adequados à avaliação dos serviços.

Among these resources are the scientific services, used to process data in certain tasks of a process of scientific experimentation. Specialized developers create and maintain these scientific services. The success of a scientific experiment depends on the correct execution of its process. As scientific services are used in process tasks, their failures undermine all experimentation. Therefore, it is important that the services are working properly. In this context, it is necessary to support the scientific services developer so that he can develop services as efficiently as possible. Therefore, the objective of this work is to present resources that seek to support the development of scientific services in a scientific software ecosystem platform. These resources are associated with a service development process that maps the activities of developers and scientists during service development. It presents an interface for contextual analysis of the services, offering elements of visualization associated with contextual information. In addition, it uses the analysis of scientific social networks to assist in the selection of better suited scientists to the evaluation of services. In order to evaluate these resources, case studies involving the development of scientific services were carried out. The results suggest that the resources employed can support the development of scientific services in a scientific software ecosystem platform.

The power of digital technology serves developers of new services as an access funnel to the vast amount of customer behavioural information. The utilization of this information is forecasted to differentiate the winners from the losers in the market and benefit the new service development process. This study explores the phenomenon of customer information in new service development empirically by looking at the industry at the forefront, the gaming industry. By conducting three case studies with leading Swedish game developers, it challenges the previous research assumptions that acquired and disseminated customer information is implicitly used. This study has made significant contributions by investigating the broader context of customer information use and differentiating among three types of use. The findings show that behavioural information is used to backup own decisions or to enhance the developers understanding, but is not directly applied to the decision task. Despite the great potential, this advanced type of customer information is only used in the post-launch stages of new service development, for service iterations. To further validate the findings and explore information use in new service development more in-depth, future research generating contextual detailed realtime data is needed.

Co-creation is a new approach to the development of videogames, films, television, music and other creative services. It is a manifestation of open innovation paradigm where the firm collaborates with customers in new service development (NSD) activities. Firm can either co-create with individual customers, or with customer communities. Customers may substantially contribute to ideation, design, production, testing, marketing or distribution of a new or existing service. Customer networks, because of their intrinsic and extrinsic motivations, contribute to the development of services. They have a potential to innovate, as their ideas come from the outside of the organization and reflect their need-related knowledge. Via co-creation a firm can also learn about unarticulated or future customer needs, and what kind of service features they would pay the most for. Co-creation has also benefits for marketing. By inviting customers to participate in their activities, firms can capitalize on positive word of mouth and increased value ascribed to their services. They can also engage in new models of raising finance, i.e. crowdfunding. We studied thirteen videogames firms in North America and in Western Europe. Our goal was to gain insight into their NSD activities when customers were also involved. We observed those studios’ co-creation practices, tracked their communications with customers, and spoke to employees in all levels and functions of those firms. We also participated in various related events. We identified three ideal types of co-creation practice: structured, semi-structured, and loose, and ordered the firms into three cases according to these types. We investigate the main factors that determine co-creation’s practice in firms, as well as firms’ ability co-create. This includes a firm’s propensity for and style of co-creation. We identify four relevant co-creation competences which, together with funding arrangements and organizational culture, influence co-creation. We find that co-creation can occur via formal, as well as informal channels. Informal co-creation takes place on the level of individual interactions between employees and customers (and is linked to hidden innovation), while formal relies on the strategic use of contests, volunteer programs, as well as other legally-regulated exchanges. Firms can use co-creation in NSD to source ideas from the customers, as well as to enhance their marketing by redefining customer relationship. Still, co-creation also has a profound transformative effect on the organization itself. We identify the sites within a firm that are affected by co-creation. Those sites go beyond just the content of the service, and include functions of the firm that normally are hidden from customers (back-end and service design functions). The new service development is also affected. Similarly, the way that firm interacts with its customers is transformed, too.

The road based transportation operations are growing rapidly, but the current infrastructure cannot sustain the entire growth. At the same time vehicle utilisation and fill rates are low. Improved efficiency of the operations is a necessary way forward for road based transportation. Parallel to this, heavy vehicle producers are currently improving the efficiency with services accompanying the product that are focused on the driver and the vehicle performance. However, the data from connected vehicles required for these services only entail a small amount of the operational data generated by connected vehicles. The case study aims to answer how to use connected vehicle operational data in order to suggest value adding services in a dynamic road distribution system. The applied methodology is an inductive study with an explanatory approach to map the current and future service offerings of the case company. This knowledge is combined with an exploratory approach with interviews of transport planners and theories of Lean and fleet management. Primarily, it is concluded that the perspective of operational data requires widening. Considering not only driver and vehicle operations but rather the entire transport operation of a company. It is also concluded that value creation with operational data is possible during three phases of fleet management. First, if knowledge about order data is accessible, the planning of transportations can be improved using route optimisation and operations research. Secondly, it is possible to create value during the execution phase, throughless manual supervision and communication by transport planners. Lastly, both the currently used operational data and further data usage can contribute to a better understanding of the performance of a fleet operation and facilitate for continuous improvements during an evaluation phase.
