The interaction in massively multiplayer online role-playing games¡]MMORPGs¡^form a considerable component in enjoyment of playing¡]Kerr, 2006¡FCole & Griffiths, 2007¡^. So player is attracted by the more interactive online gaming. Therefore interaction is extremely important for MMORPGs. However, according to Freeman (2004), much of the research focused on individual behavior, but ignored the social dimensions of the influence between relationships and individual behavior. The research of online gaming has neglected that too. Therefore, the purpose of this study is to explore how is the social network of MMORPGs players in the game¡HAnd what effect will social network have on players¡¦ interaction patterns¡H In this paper, the survey has been completed online by 337 players, who reported on their buddy list, ego-centered network, and interaction patterns. This study explored that male role is more skilled in technical behavior¡Fthe social capital of players involved in online gaming communities is more prosperous. It is found that the ego-centered network of players positively affects players¡¦ interaction patterns. Friendships are connected with strong ties, but acquaintances are connected with weak ties. Both of them could affect players¡¦ interaction patterns, but the influence of friendship is relatively higher than that of acquaintance on players¡¦ interaction patterns.

Research to date discovered two gaps restricts the existing service innovation theories from full support for SMEs - who also require good service innovation theory to innovate and to survive in the fast-pacing market - which are: goods-thinking-based service innovation logic and incomprehensible service innovation theory for SMEs. In this research, we share and enhance the vision of system thinking researchers - interaction plays the very basis and important role in service value creating and delivering - as our theory foundation. Founding on this interaction-centric notion, we propose an easy-to-adapt service innovation methodology which suggests that SMEs could do service innovation by adjusting business interactions, and justify it with a comprehensive model evaluated by simulation techniques and a prototype supporting information system mechanism to provide support for SME users. Last but not the least, at the end of this research, we re-examine the system thinking framework with our discoveries, and signaled a possible adjusting direction of the framework for more value-oriented purposes. From the practical view, we identify a way to extend the current system thinking theory to a practical model for real world SME’s service innovation purposes. For the academic research, our interaction-centric service innovation methodology is believed to enhance the to-date system thinking theories. In addition, we also identify several future possibilities for academic researchers in this field to discover.

As aulas expositivas dialogadas são aquelas nas quais os professores dialogam com os alunos, atuando como mediadores dessas aulas. O diálogo é um dos momentos em que pode ocorrer o processo de ensino e aprendizagem. Neste trabalho, foi analisada uma aula expositiva dialogada que foi ministrada 2 vezes pela mesma professora do 1º ano do ensino médio regular de uma escola pública da zona oeste da cidade de São Paulo. Nessa aula, foi realizada a correção de exercícios de uma ficha de atividades sobre dinâmica populacional. Essa ficha fazia parte de uma sequência de ensino investigativa (SEI) que incluía algumas atividades. As aulas foram áudio-vídeo gravadas, transcritas e analisadas sob o ponto de vista de 3 aspectos de 2 referenciais metodológicos, que foram os tipos de iniciações/perguntas (MEHAN, 1979) e os padrões de interação e a abordagem comunicativa (MORTIMER E SCOTT, 2002). Esses referenciais foram combinados uns aos outros para que a nossa análise ficasse mais completa. Os padrões de interação foram associados aos tipos de iniciações e os mesmos padrões foram analisados individualmente, seja em relação aos padrões triádicos, não triádicos abertos ou fechados. A abordagem comunicativa também foi analisada individualmente. Nossa hipótese inicial era que iniciações de metaprocesso desencadeariam sequências de interação mais longas e interativas. Porém, nossa hipótese não foi confirmada e constatamos que iniciações mais simples como as de escolha e de produto desencadearam sequências de interação mais longas. Em relação aos padrões de interação, a maioria era de não triádicos fechados, o que mostrou que a aula foi bem dinâmica e interativa e essa interação terminava com uma avaliação da professora, na maioria das vezes. Em relação à abordagem comunicativa, a interativa de autoridade foi a presente na maioria do discurso, demonstrando que o objetivo da professora era ouvir os pontos de vista dos alunos e encaminhá-los para o ponto de vista da ciência escolar. A abordagem interativa dialógica também esteve presente em algumas partes do discurso quando não havia avaliação das falas dos alunos pela professora. / The expository - negotiated lessons are those in which teachers interact with their students, becoming mediators. This interaction is one moment that can happen the teaching and learning process. This research analysed a expository - negotiated lesson that was given twice by the same teacher from a public school in the west zone of São Paulo. In this lesson, the teacher was correcting questions from activities form about population dynamics. This form was part of a didactic sequence with some activities. The lessons were recorded, transcribed and analysed in 3 aspects of 2 methodological standards: inicialization / questions types (MEHAN, 1979); interaction patterns and communicative approach (MORTIMER E SCOTT, 2002). These standards were combined in order to become our analysis more complete. The interaction patterns were associated to the inicialization types and the same patterns were analysed individually, in relation to the triadic and non triadic patterns. There were 2 types of non triadic patterns: the open and the closed ones. The communicative approach was also analysed individually. Our initial hypothesis were that metaprocess initiations could trigger longer and interactive interaction patterns. But our hypothesis was not confirmed and we establish that more simple initiations like choice and product types triggered longer interaction patterns. In relation to interaction patterns, most of them were closed non triadic, which meant that the lesson was very dynamic and interactive. And this interaction ended with a teacher evaluation most of the times. With respect to the communicative approach, the interactive of authority was present in most of all discourse, showing that the teacher aim was listen the students point of view to take them to the educational science point of view. The dialogical interactive communicative approach was present in some discourse parts when the teacher did not evaluate the students speeches.

In this thesis, the interaction pattern for a class of soliton solutions of the Kadomtsev- Petviashvili (KP) equation (−4ut + uxxx + 6uux )x + 3uyy = 0 is analyzed. The complete asymptotic properties of the soliton solutions for y → ±∞ are determined. The resonance characteristic of two sub-classes of the soliton solutions, in which N- incoming line solitons for y → −∞ interact to form N+ outgoing line solitons for y → ∞, is described. These two specific sub-classes of (N-,N+)-soliton solutions are the following: 1) [(2, 3), (2, 4), (2, 5)], 2) [(3, 2), (3, 3), (3, 4)]. The intermediate solitons and the interaction regions of the above soliton solutions are determined, and their various interaction patterns are explored. Maple and Mathematica are used to get the 3 dimensional plots and contour plots of the soliton solutions to show their interaction patterns. Finally, the spider-web-structures of the discussed solitons of the KP equation are displayed.

The research aims at modeling and analyzing the interactions among functional process variables (FPVs) for process control in semiconductor manufacturing. Interaction is a universal phenomenon and different interaction patterns among system components might characterize the system conditions. To monitor and control the system, process variables are normally collected for observation which could vary with time and present in a functional form. These FPVs interact with each other and contain rich information regarding the process conditions. As an example in one of the semiconductor manufacturing processes, changes of interactions among FPVs like temperature and coefficient of friction (COF) might characterize different process conditions. This dissertation systematically developed a methodology to study interaction among FPVs through statistical and physical modeling. Three main topics are discussed in this dissertation: (1) Interaction patterns of FPVs under varying process conditions are studied both through experiments and statistical approaches. A method based on functional canonical correlation analysis (FCCA) is employed to extract the interaction patterns between FPVs and experiments of wafer polishing processes are conducted to verify the patterns of FPVs under varying process conditions. (2) Interaction among FPVs is further studied based on physics for process condition diagnosis. A mathematical model based on nonlinear dynamics is developed to study the strength of interaction and their directionalities, and advanced statistical control charts followed by this nonlinear dynamics model are established for process monitoring. (3) Complex interaction structures among multiple FPVs are analyzed based on nonlinear dynamics for a better understanding of process mechanism. An approach with extended nonlinear dynamics model is proposed to characterize process conditions, and combined engineering knowledge, complex interaction structure patterns are concluded accordingly for interpretation of process mechanism. The main contribution of this dissertation is to propose a novel methodology based on nonlinear dynamics, which could investigate interactions between components of systems and provide physical understanding of process mechanism for process monitoring and diagnosis. Through studies on interaction among FPVs in semiconductor manufacturing, this research provides guidance for improvement of manufacturing processes. Not limited to manufacturing, the developed methodology can be applied to other areas such as healthcare delivery.

This thesis is concerned with the work of business leaders. The interest lies in the holders of positions as Chairpersons, Boardmembers and Managing Directors. This study, however, goes beyond the position holder to consider the actions of actors, as they operate within networks with concurrent multiple business activities. The purpose is to generate knowledge and understanding of the activities and relations of multibusiness leaders involved in managing small and medium-sized companies. Major schools of thought on the manager's job are described. The review relates the scientific debate about different schools and emphasises the need for more inductive research. The call for processual and contextual analysis leads to an epistemological position grounded in understanding through interpretation. The method used in this study adopts such an approach, and thus aims to discover qualities of the studied phenomenon based on social constructivism. Empirical reality is approached by means of intensive studies of a few cases. Case descriptions of the work of multibusiness leaders in the National, Regional, Intermediary, Independent, and Developing Networks are undertaken, where the inter­action processes of the different actors are described according to the working life his­tory of the actor, and to the networking and work activities carried out. The analysis is based upon four themes (the actor's 'task legitimacy', 'economic legi­timacy', 'idea development' and 'network'). The first two themes have been given the generic term 'legitimacy concept', not only to reflect the interactive and changeable aspects of work, but also to illustrate how work in itself is intimately interwoven in an institutional context. The creation of 'task legitimacy' and 'economic legitimacy' of the leaders is analysed. The analysis of the actors' idea development results in a description of differing visions in the individual networks. This description takes up visions covering long-term industrial leadership, regional co-operative leadership, restructuring leadership, flexible market-adaptive leadership and network-based leadership. In a survey of the existing literature, the role of a leader is seen as one of many managerial roles, a view that is based upon the work of Mintzberg (1973). This study contrasts with the above picture, by discussing a reciprocal dependency between the leader's leadership role and his/her other roles. This reciprocity and concurrency is dealt with by introducing the concept of identity as a theoretical aid, thus reflecting in a more appropriate way the complex and interactive actor. The social identity concept (Tajfel, 1982) is used, in order to answer more profoundly the research questions. As leaders are reciprocally dependent on a network for their own existence, we must both look inward in order to be able to understand at a deeper level the actors' motives, and look outward to be able to look at identity creation in a wider industry context. What I have termed näringslivsledaridentitet (the Identity of Multibusiness Leaders), is a substantial part of this study's findings. The concept is used in order to be able to describe how the actors' inner and outer motives merge in identity creating processes. The actors' different patterns of interaction are absorbed into a composite whole. / digitalisering@umu

Recent years have shown a broad spectra of tangible interfaces or TUI's, based upon interaction with music, but also other interfaces containing ubiquitous computing. This is an interesting field due to how engaging music can be and work as connector between people. But the field of human computer interaction has some explorational properties. This paper presents an idea of abstraction with a tangible interface for creating music. The idea behind abstraction of the interface is to engage the user(s) in exploring the artifact, rather than explaining the artifact to the user what can and cannot be done with the artifact.

In particular, social interactions that are centered around and reinforcing of antisocial values, known as deviant peer contagion, are predictive of a variety of antisocial outcomes, including substance use. However, much less is known about the interpersonal dynamics between friends that are associated with resilience to peer contagion. Recent work has associated self-regulation with resilience to the effects of associating with deviant and substance-using peers. Limited resource models of self-regulation have proposed that social interactions may tax regulatory resources to the point that self-regulation becomes impaired. Youth with more limited regulatory resources may demonstrate increased susceptibility to influence from peers. However, in friendship interactions, self-regulatory behaviors are highly dependent on the self-regulation of the partner. Therefore, the present study examined dyadic regulation in friendship interactions consistent with the idea of a dyadic process. In addition to investigating the construct validity of dyadic regulation, it was hypothesized that dyadic regulation would moderate the impact of peer contagion on problematic substance use. Furthermore, consistent with a limited resource model, it was predicted that adolescents with declining dyadic regulation over the course of an interaction would be more susceptible to peer contagion. Problematic substance use and interaction patterns within friendships were assessed in a sample of 711 (355 male, 356 female) ethnically diverse 16- and 17-year-old adolescents. Using videotaped observations of friendship interactions, dyadic regulation was assessed by rating responsiveness, self-focused intrusions, attention, and conversational turn-taking. Deviant peer contagion was assessed through the proportion of the interaction spent discussing deviant topics. Contrary to the hypothesized self-regulatory resilience model, those dyads that were more highly regulated while discussing deviant topics demonstrated the highest levels of problematic tobacco use. Consistent with a limited resource model of regulation, however, dyads with decreasing regulation over the course of an interaction appeared to be the most vulnerable to deviant peer contagion, demonstrating greater problematic marijuana use. These results are encouraging of further investigation in this area and may have implications for direct interventions targeting risk for substance use as well as reducing iatrogenic effects in group interventions. / Adviser: Thomas J.

Denna kvalitativa studies syfte är att undersöka, kartlägga och analysera sociala interaktionsmönster kring beslutsprocessen på Migrationsverkets asylprövning utifrån asylbeslutsfattares perspektiv. Genom att luta sig mot teori om beslut inom ramen för administrativt beteende samt teori om ansvarfördelning analyseras empirisk data insamlat med hjälp av semistrukturerade intervjuer med beslutsfattare från olika asylprövningsenheter.Studiens resultat visar att det finns invecklade sociala interaktionsmönster i asylbeslutsfattandet samt att tre kommunikationstyper kunde identifieras; informella, formella och semiformella. Beslutsfattare växlar mellan dessa typer i beslutsprocessens olika steg. Med hjälp av utvecklade sociala kommunikationsmönster, omsätts en tidspressad beslutsplan i handling. Sammantaget påvisar studien den administrativa människans begränsade rationalitet. På grund av ringa sociologiska forskning inom området är studien ett bidrag till disciplinen. / This qualitative study aims to investigate, identify and analyze social interaction patterns regarding the decision-making process at the Migration board’s asylum processing unit from the perspective of the asylum officer. Empirical data, which is collected through semi-structured interviews with asylum officers from different Migration board entities, is analyzed by employing different theories on decision-making in the context of administrative behavior and diffusion of responsibility. The outcome of the study shows that there is an intricate social interaction pattern in the asylum decision process and three communication types have been identified: informal, formal and semi-formal. The asylum officer switches between these types in the various stages of the decision-making process. Through developed social communication patterns, a time-pressured decision-making plan is put in action. Generally, the study demonstrates the bounded rationality of the administrative person. Due to lack of sociological research in this area, this study is a contribution to the field.

Cancer is a leading cause of death worldwide. Development of new cancer drugs is increasingly costly and time-consuming. By exploiting massive amounts of biological data, computational repositioning proposes new uses for old drugs to reduce these development hurdles. A promising approach is the systematic analysis of structural data for identification of shared binding pockets and modes of action. In this thesis, I developed the Protein-Ligand Interaction Profiler (PLIP), which characterizes and indexes protein-ligand interactions to enable comparative analyses and searching in all available structures. Following, I applied PLIP to identify new treatment options in cancer: the heat shock protein Hsp27 confers resistance to drugs in cancer cells and is therefore an attractive target with a postulated drug binding site. Starting from Hsp27, I used PLIP to define an interaction profile to screen all structures from the Protein Data Bank (PDB). The top prediction was experimentally validated in vitro. It inhibits Hsp27 and significantly reduces resistance of multiple myeloma cells against the chemotherapeutic agent bortezomib. Besides computational repositioning, PLIP is used in docking, binding mode analysis, quantification of interactions and many other applications as evidenced by over 12,000 users so far. PLIP is provided to the community online and as open source.
