The concept of BIM is nascent but evolving rapidly, thus, its deployment has become the latest shibboleth amongst both academics and practitioners in the construction sector in the recent couple of years. Due to construction clients buy-in of the BIM concept, the entire industry is encouraged to pursue a vision of changing work practices in line with the BIM ideas. Also, existing research recognises that the implementation of BIM affects all areas of the construction process from design of the building, through the organisation of projects, to the way in which the construction process is executed and how the finished product is maintained. The problem however is that, existing research in technology utilisation in general, and BIM literature in particular, has offered limited help to practitioners trying to implement BIM, for focusing predominantly, on technology-centric views. Not surprisingly therefore, the current BIM literature emphasises on topics such as capability maturity models and anticipated outcomes of BIM rollouts. Rarely does the extant literature offer practitioners a cohesive approach to BIM implementation. Such technology-centric views inevitably represent a serious barrier to utilising the inscribed capabilities of BIM. This research therefore is predicated on the need to strengthen BIM implementation theory through monitoring and analysing its implementation in practice. Thus, the focus of this thesis is to carry out a sociotechnical systems (STS) analysis of BIM implementation in construction organisations. The concept of STS accommodates the dualism of the inscribed functions of BIM technologies and the contextual issues in the organisations and allows for the analysis of their interactive combination in producing the anticipated effect from BIM appropriation. An interpretive research methodology is adopted to study practitioners through a change process, involving the implementation of BIM in their work contexts. The study is based on constructivist ontological interpretations of participants. The study adopts an abductive research approach which ensures a back-and-forth movement between research sites and the theoretical phenomenon, effectively comparing the empirical findings with the existing theories and to eventually generate a new theoretical understanding and knowledge regarding the phenomenon under investigation. A two-stage process is also formulated for the empirical data collection - comprising: 1) initial exploratory study to help establish the framework for analysing BIM implementation in the construction context; and 2) case studies approach to provide a context for formulating novel understanding and validation of theory regarding BIM implementation in construction organisations. The analysis and interpretation of the empirical work follows the qualitative content analysis technique to observe and reflect on the results. The findings have shown that BIM implementation demands a complete breakaway from the status quo. Contrary to the prevailing understanding of a top-down approach to BIM utilisation, the study revealed that different organisations with plethora of visions, expectations and skills combine with artefacts to form or transform BIM practices. The rollout and appropriation of BIM occurs when organisations shape sociotechnical systems of institutions, processes and technologies to support certain practices over others. The study also showed that BIM implementation endures in a causal chain of influences as different project organisations with their localised BIM ambitions and expectations combine to develop holistic BIM-enabled project visions. Thus, distributed responsibilities on holistic BIM protocols among the different levels of influences are instituted and enforced under binding contractual obligations. The study has illuminated the centrality of both the technical challenges and sociological factors in shaping BIM deployment in construction. It is also one of the few studies that have produced accounts of BIM deployment that is strongly mediated by the institutional contexts of construction organisations. However, it is acknowledged that the focus of the research on qualitative interpretive enquiry does not have the hard and fast view of generalising from specific cases to broader population/contexts. Thus, it is suggested that further quantitative studies, using much larger data sample of BIM-enabled construction organisations could provide an interesting point of comparison to the conclusions derived from the research findings.

Enabled by advanced communication and information technologies, the smart grid represents a major transformation for the electricity sector. Vast quantities of data and two-way communications abilities create the potential for a flexible, data-driven, multi-directional supply and consumption network well equipped to meet the challenges of the next century. For electricity service providers (“utilities”), the smart grid provides opportunities for improved business practices and new business models; however, a transformation of such magnitude is not without risks. Three related studies are conducted to explore the implications of the smart grid on utilities’ demand-side activities. An initial conceptual framework, based on organizational information processing theory, suggests that utilities’ performance depends on the fit between the information processing requirements and capacities associated with a given demand-side activity. Using secondary data and multiple regression analyses, the first study finds, consistent with OIPT, a positive relationship between utilities’ advanced meter deployments and demand-side management performance. However, it also finds that meters with only data collection capacities are associated with lower performance, suggesting the presence of information waste causing operational inefficiencies. In the second study, interviews with industry participants provide partial support for the initial conceptual model, new insights are gained with respect to information processing fit and information waste, and “big data” is identified as a central theme of the smart grid. To derive richer theoretical insights, the third study employs a grounded theory approach examining the experience of one successful utility in detail. Based on interviews and documentary data, the paradox of dynamic stability emerges as an essential enabler of utilities’ performance in the smart grid environment. Within this context, the frames of opportunity, control, and data limitation interact to support dynamic stability and contribute to innovation within tradition. The main contributions of this thesis include theoretical extensions to OIPT and the development of an emergent model of dynamic stability in relation to big data. The thesis also adds to the green IS literature and identifies important practical implications for utilities as they endeavour to bring the smart grid to reality. / Thesis (Ph.D, Management) -- Queen's University, 2013-01-21 12:04:43.652

This thesis investigates whether and how public policies can help build industrial clusters. The research applies a case study method based on 60 interviews to the emerging information communication technology (ICT) clusters in Scotland and Hong Kong. The analysis uses Molina’s sociotechnical constituency (STC) framework and its associated ‘diamond of alignment’, which help focus on two interrelated dimensions: 1) the complex technical and social aspects of the design, implementation and evolution of the Scottish and Hong Kong ICT clusters and 2) the difficulties of developing a cluster in the context of major diversity of organisational interests and patterns of interaction. This research revealed that the cluster building effort in the two regions has been fraught with difficulties due to misalignment between the perceptions and pursuits of policy makers and the interests of industry members. This thesis concludes that cluster building is an evolutionary process of sociotechnical alignment which can be facilitated by feedback and learning. It also suggests that for successful cluster building to take place, policy makers should focus on stimulating the processes of cluster formation, including the building up of the technological capabilities of the industrial actors, while facilitating the integration of the major actors’ interests and demands with the policy programmes. Cluster building involves the development of new ways of thinking as well as the practice of networking; it necessitates the coherent effort of collective learning and a long-term commitment to change the existing technological system. A long-term adaptive policy programme should be pursued to focus on effectively aligning the interests and pursuits of the different actors in the cluster at various stages.

As práticas ágeis de desenvolvimento de sistemas de software são, neste trabalho, classificadas sob três aspectos: dependabilidade, domínios do ESSENCE e guidelines para redução de erro humano. A partir dessa classificação, um questionário baseado nas práticas relacionadas aos fatores humanos foi aplicado para desenvolvedores de sistemas de software com diferentes níveis de experiência com o objetivo de avaliar a interferência do ambiente na dependabilidade do sistema de software desenvolvido. O questionário foi respondido por 125 desenvolvedores. Os desenvolvedores foram separados em dois grupos e os grupos foram comparados em relação à percepção de certos guidelines para desenvolvimento de software para cada prática considerada. Os resultados do questionário mostraram que a utilização das práticas ágeis analisadas aumentou fatores que reconhecidamente facilitam a redução do erro humano. / In this work, agile software development practices are categorized using three aspects: reliability, ESSENCEs areas of concern and guidelines for human error reduction. From this categorization, it was applied to software developers with different levels of expertise a questionnaire with practices related to human factors with the goal of evaluating the interference of the environment on the reliability of the developed software. The questionnaire was answered by 125 developers. For every practice considered the developers were separated in two groups and compared in relation to the perception of certain guidelines. The results show that the use of those agile practices increase factors that help reduce human error.

Uma metodologia que combina mapeamento e análise de processos, elicitação, mapeamento e análise crítica de conhecimentos e análise sociotécnica com base em análise de redes sociais foi concebida. A metodologia foi aplicada à uma pequena organização intensiva conhecimento LNMRI e permitiu a avaliação dos seus principais ativos intelectuais e sua capacidade de evoluir. Nesse sentido, com base em questões reais, tal como a saída de pessoas da organização, foram avaliados os impactos de prováveis cenários futuros. Para tal tarefa, foi analisada uma rede multimodal de processos, objetos de conhecimento e pessoas, utilizando-se um conjunto apropriado de métricas e meios, incluindo a avaliação das esferas de influências de nós chave. Para diferenciar a capacidade das pessoas em desempenhar diferentes papeis nos processos, alguns atributos dos nós foram utilizados como critérios de partição da rede, proporcionando assim, a capacidade de diferenciar o impacto da perda potencial de supervisores e operadores. A metodologia proposta possibilitou: i) a identificação de objetos de conhecimento e de suas fontes; ii) a classificação desses objetos segundo sua relevância; iii) a avaliação de vulnerabilidades da estrutura da rede LNMRI e iv) revelou os mecanismos informais de partilha de conhecimento. A metodologia concebida demonstrou ser uma ferramenta robusta para um amplo diagnóstico para subsidiar o planejamento de sucessão e também o planejamento estratégico organizacional. / A methodology combining process mapping and analysis; knowledge elicitation mapping and critical analysis; and sociotechnical analysis based on social network analysis was conceived. The methodology was applied to a small knowledge intensive organization LNMRI, and has allowed the appraisal of the main intellectual assets and their ability to evolve. In this sense, based on real issues such as attrition, the impacts of probable future scenarios were assessed. For such task, a multimodal network of processes, knowledge objects and people was analyzed using a set of appropriate metrics and means, including sphere of influence of key nodes. To differentiate the ability of peoples role playing in the processes, some nodes attributes were used to provide partition criteria for the network and thus the ability to differentiate the impact of potential loss of supervisors and operators. The proposed methodology has allowed for: i) the identification of knowledge objects and their sources; ii) mapping and ranking of these objects according to their relevance and iii) the assessment of vulnerabilities in LNMRIs network structure and iv) revealing of informal mechanisms of knowledge sharing The conceived methodological framework has proved to be a robust tool for a broad diagnosis to support succession planning and also the organizational strategic planning.

The innovative advancements of information communication technology (ICT) combinedwith a globalized economy have given rise to organizational forms that manipulate timeand distance. Today, competitive advantages are more elusive than tangible as a result ofdynamically complex environments motivating organizations to adjust in structure andfunctional capacity. New emergent forms of organizational structures have resulted inthe virtual organization (VO), which employs a network structure and allowsorganizations the flexibility to perform core processes amongst distributed teams, units,departments, and/or organizations. In essence the virtual organization may be viewed asa strategic response to dynamic environmental forces that have encouragedorganizations to rethink the concept of competitiveness. Virtual organizations havegained popularity throughout the last decade as a more effective way of managing andcommunicating information within and across organizations. Information communicationtechnology (ICT) has aided in the globalizing effect of informationalism. Theinformational flows within a virtual organization have direct bearing on individual andgroup efforts to obtain and employ information essential to organizational objectives.This thesis investigates the information interchange within virtual organizations througha theoretical study, which converges identified relevant subject areas and introduces theMedia Rich Social Information Interchange (MERiSii) model. The empirical study isdesigned to further investigate the validity of theoretical concepts employed in theMERiSii model and to expand its development to facilitate the function of informationinterchange. VGR-IT is an IT infrastructure provider, for hospitals and healthcarefacilities in the Västra Götaland region of Sweden. Interviews conducted with an accountmanager for VGR-IT and an IT strategist for Borås Hospital give insight into thecommunicative tasks of information interchange that must be effective to support the coreprocesses within VGR-IT and the service VGR-IT provides to Borås hospital. The resultsof a comparative analysis between the theoretical and empirical studies support a revisedMERiSii model that may be implicated in future research to further verify itseffectiveness. / Program: Magisterutbildning i informatik

Les transitions agroécologiques impliquent une transformation radicale des modes de production, mais également des modes de transformation, de distribution et de consommation, du conseil agricole, des politiques publiques et de la recherche - en d’autres termes : une reconfiguration du système agri-alimentaire. Dans la vallée de la Drôme, la forte proportion d’acteurs plaçant l’agriculture biologique au coeur de leur stratégie de développement et leur collaboration dans le projet Biovallée semblent indiquer qu’une transition agroécologique est en cours et que l’échelle territoriale offre des leviers permettant de la déclencher. Cette thèse propose une analyse historique des dynamiques à l’oeuvre sur ce territoire, afin de contribuer à la compréhension des mécanismes de transition et à leur conceptualisation. En mobilisant la théorie des transitions sociotechniques et à travers une approche pragmatique et ethnographique, nous montrons qu’une reconfiguration du système agri-alimentaire territorial est en cours, et qu’elle résulte des interactions entre une configuration sociotechnique dominante et deux configurations alternatives qu’ont construites les acteurs au fil du temps, autour de deux paradigmes alternatifs à la modernisation agricole. Nous montrons comment, à travers ces interactions, les acteurs parviennent à modifier les rapports de force régissant le système agri-alimentaire, et que l’échelle territoriale leur offre des marges de manoeuvre inexistantes à une échelle plus large. Nous mettons en évidence le rôle essentiel d’une diversité d’initiatives, au sein desquelles les acteurs ont progressivement construit de nouvelles formes de coordination. Dès lors, la question est non plus de penser les transitions à partir du développement d’une innovation technique, mais de créer les conditions pour favoriser la coexistence d’une diversité d’initiatives, porteuses d’innovations sociales, et leurs interactions avec le système dominant. / Agriculture’s transition towards agrocology requires a radical transformation of production practices based on ecological principles, but it also requires radical changes within transformation, distribution and consumption practices and within advisory systems, public policies and research. In other words, it requires a profound reconfiguration of the whole agrifood system. In the Drome Valley (France), the high proportion of actors who consider organic agriculture as central in their development strategy and their involvement within the “Biovallée” project, suggest that an agroecological transition is in process and that the territorial scale might facilitate it. This thesis analyses the agricultural dynamics at the scale of this territory since the 1970s, in order to understand the transition mechanisms and to conceptualize them. Based on a framework inspired from the sustainable transition theories and on an ethnographic and pragmatic approach, it shows that a reconfiguration of the whole local agrifood system is indeed in process, and that it results from the interactions between a dominant sociotechnical configuration and two alternative ones which local actors have set up over time around two alternative paradigms. We analyze how actors succeed in changing the balance of power within the local agri-food system and how the territorial scale offers them some levers which do not exist on a larger scale. In this case, certain traditional actors and a diversity of initiatives allowed actors to progressively set up new forms of coordination, that is social or organizational innovations (rather than technological ones). Therefore the main issue shifts from thinking transitions based on the development of atechnological innovation, towards creating conditions in order to favour the coexistence of a diversity of initiatives that develop social innovations and to favour their interactions with the dominant system.

Process control is essential in chemical engineering and has diverse applications in automation, manufacturing, scheduling, etc. In this cross-disciplinary work, we shift the domain focus from the control of machines to the control of multiple intelligent agents. Our goal is to improve the optimization problem-solving process, such as optimal regulation of emerging technologies, in a multi-agent system. Achieving that improvement would have potential value both within and outside the chemical engineering community. This work also illustrates the possibility of applying process systems engineering techniques, especially process control, beyond chemical plants. It is very common to observe crowds of individuals solving similar problems with similar information in a largely independent manner. We argue here that the crowds can become more efficient and robust problem-solvers, by partially following the average opinion. This observation runs counter to the widely accepted claim that the wisdom of crowds deteriorates with social influence. The key difference is that individuals are self-interested and hence will reject feedbacks that do not improve their performance. We propose a multi-agent control-theoretic methodology, soft regulation, to model the collective dynamics and compute the degree of social influence, i.e., the level to which one accepts the population feedback, that optimizes the problem-solving performance. Soft regulation is a modeling language for multi-agent sociotechnical systems. The state-space formulation captures the individual learning process (i.e., open loop dynamics) as well as the influence of the population feedback in a straightforward manner. It can model a diverse set of existing multi-agent dynamics. Through numerical analysis and linear algebra, we attempt to understand the role of feedback in multi-agent collective dynamics, thus achieving multi-agent control in sociotechnical systems. Our analysis through mathematical proofs, simulations, and a human subject experiment suggests that intelligent individuals, solving the same problem (or similar problems), could do much better by adaptively adjusting their decisions towards the population average. We even discover that the crowd of human subjects could self-organize into a near-optimal setting. This discovery suggests a new coordination mechanism for enhancing individual decision-making. Potential applications include mobile health, urban planning, and policymaking.

The work "Modelling the human approach to world" is part of the mutlidisciplinary field of informatics which deals with production and use of information systems in enterprises and other communities. It contributes to its development in the area of human-machine relationship and communicating information. At present information systems (IS) are used for collecting, distributing, storing, processing and conveying information. Their components are hardware (machines) and software. Without information systems today's work with information wouldn't be possible. People remain in spite of intensive implementation of information technologies the main element for companies' operation. Information technologies help man, cannot replace him however. To understand the role of information technologies it is important to be aware of the difference between man and machine (computer) information processing from which we can deduce the implications for business operation. The computer is only able to work with a reality model prepared by a human being. Reality is in information systems represented by means of signs. Even though we can understand the information system as a tool similar to classical tools (typing machine, filing cabinet etc.), there is a difference, because these tools don't exist as physical objects, but only as signs. The symbolic nature of information systems didn't interest researchers in the past very much, but now it increases. The first reason can be found in the massive implementation of information and communication technologies (ICT), which calls for intelligibility of their representation; the second reason can be found in the fact that computers are used as media with functions similar to textbooks, letters, newspapers, telephones, films, where the importance of semiotics has already been recognized. The advancement of hardware requires from software developers abilities similar to professional artists. The third reason lies in the fact that production processes are more and more controlled by computers. Cooperating people must rely on symbols mediated by computers (Andersen, 1997). IS are more complex and important is their influence on people on many levels and through many means. Structuralism may be of some help as it studied similar phenomena in the first half of the 20th century. In the first part of my work I described the differences between human and computer information processing, in the second part I analysed the modelling theories which take into account the human approach and at the end I deduced general conclusions for the relationship between man and computer in information system and suggested some recommendations on how to improve their relationship and make human understanding and use of information in information system easier. One of the researchers who studied the difference between man and machine was Hubert Dreyfus. He came to the conclusion that there is a principle difference between man and machine. He identified some typical situations where man and machine differ: Rule following, bodily existence, situations, pattern recognition etc. Dreyfus' analysis will be supplemented with the analysis of public space, intentionality and language. I don't want to present a complete description of human approach to world, I rather sketch some key points to clarify the difference between man and machine. From the analysis of man and machine two conclusions emerge: on the one hand proposal how to analyse and propose information system which would better connect subjective and objective aspects; on the other hand importance of IS integration into the business culture and the whole context of human work. As a suitable approach appears in compliance with P. Ricoeur structuralism and its analysis of narrativity. In the area of IS development there are four so called socio-technical theories which try to incorporate some principles of human approach to world into their modelling procedures and balance the superiority of technical view on the human computer interaction. The main common feature of these theories lies in the emphasis on the importance of human factor for organisations (they consider organisations social systems). The role of technical equipment is seen in the support of human activities. They are called Language Action Perspective, specifically methodology DEMO, Organisational Semiotics, Theory of Organised Activity and Human Interaction Management. DEMO methodology focuses on communication which is analysed by means of four axioms based on the language act theory. The theory differentiates between locution, illocution and perlocution. Locution deals with the proposition's content, illocution is related to the intention which we communicate the proposition with and perlocution contains effects in the addressee. From these three perspectives production and communication acts are analysed. Organizational semiotics deals with the semiotic aspect of human communication. It uses a six-stage semiotic ladder with physical, empirical, syntactic, semantic, pragmatic and social level. On all these levels communication and its signs are analysed. On the first three levels machines can be used, on the next three levels the human work with information is carried out and machines don't help there much. Organisational semiotics emphasizes the social level where organisational, social and cultural norms play an important role. Theory of organized activity is based on the theory of units which the group has in common. The theory divides the world on actors and things. For the activity to start both these elements must be present. Typical features of actors are interest and responsibility. The human interaction management tries to modify the proposal and functioning of information systems in order to respect the principles of human work. The basic argument of human interaction management is that most processes where people are involved is in instant change which cannot be governed by rules independent of the process participants. Flexibility is necessary for success. K.H. Broninski, the author of Management of Human Interaction, calls for support for mental work a transformation of information into knowledge. He proposes a procedure structuring work. It consist of five parts: research, evaluation, analysis, constrain, task. Another piece of knowledge of the Human interaction management is that a big proportion of human work has small concrete results, and cannot be quantified. However time spent on researching, comparing, evaluating, generally information processing and their transformation into knowledge, is a substantial part of a worker cooperating with colleagues and other people. It is better for employees to have supportive rather than directive leadership, as people are individuals. People do things in different times, in different ways, on the basis of communication with others, according to the state of resources and their mood. They do what they consider most appropriate in given situation. Continual process change must be possible and it is necessary to support it. Human activities are creative, exploratory and loosely structured. The socio-technical theories neither explicitly address the difference between man and machine nor try to unify their perspectives organically. However they show some content elements which are important for human beings. When considering the human approach to world we cannot be limited to a set of perceptions where man and machine differ. We should consider their arrangement which allows for new ways of understanding reality. The synthesis of the elements can be carried out only when the elements are linked together into a structure, e.g. a plot. Another problem lies in the necessity to consider time. Progressive development and its modalities constitute integral part of a homogenous stylistic form. Two rationalities are at work here; the one understands the world in its unity mediated by a form, best of all and most generally by a narrative; the other systemizes the first understanding and transforms it onto a syntactic level. The modelling techniques use the second syntactic rationality; we can reach it only in time, however. Stories have many advantages in comparison to other ways of conveying information: aims, causes, chances, agents are unified in time and space into a plot. Originally different elements are unified in the plot. They seem accidental; however they gain necessity in the plot. Other important aspects are source of information, narrator, rhythm, repetition and focalization. These elements can be separated on three levels: text, plot, fabula. They concentrate on different elements and their relations. We will use the results of work of the structuralist J. Greimas and his theory of actants suggesting which role can be considered in narrative information conveying. His semiotic square is a method of understanding context elements. Analysis of the elements of narrative which are the results of structuralist research cannot substitute the narrative understanding; we can only approximate it and explain it in further details. We encounter a creative act which cannot be reduced on rules and formalized. That is why a creative approach of the author is necessary in the development of IS. The conclusion achieved in the analysis of differences between human and machine that human understanding and behaviour is not completely formalizable was found in our attempt to use the structuralist approach on design and functioning of information systems. The interconnection of objective world of machines with the subjective human understanding is possible in a story created by a creative human being able to ensure organic and natural unity.

nÃo hà / A tese de doutoramento âUm cais que abriga histÃrias de vida: homens e mÃquinas construindo o social na cidade de Macapà (1943-1970)â à um estudo sobre as sociabilidades que deram forma a existÃncia na cidade de MacapÃ. A narrativa versa sobre as interaÃÃes, redes sociais e relaÃÃes sociotÃcnicas estabelecidas no cotidiano do processo de gentrificaÃÃo da Cidade, em um perÃodo de predomÃnio do poder local pela famÃlia Nunes no TFA (1943-70). O estudo laboratorial teve em vista apreender como se construiu o social na cidade de MacapÃ, quando este MunicÃpio passava por mudanÃa social na sua estrutura urbana. A sociabilidade foi o caminho pelo qual pressupus a forma possÃvel de como apreender as construÃÃes coletivas, que possibilitam a realizaÃÃo ou nÃo das vontades singulares ou plurais da vida social. Portanto, o experimento fundamentou-se na abordagem das sociabilidades e associaÃÃes simÃtricas, inspirados, em Simmel, dentre outros aportes, concepÃÃo teÃrica que implicou na necessidade de acolher categorias analÃticas como poder, cotidiano, redes sociais, relaÃÃes sociotÃcnicas. A atividade de campo teve como fundamento o gÃnero biogrÃfico, constituÃdo pela modalidade trajetÃria de vida como possibilidade concreta de reconstruÃÃo do passado a partir de relatos, levando em conta a descontinuidade e as rupturas ocorridas tanto no nÃvel da vida individual como coletiva. Entrementes, o material examinado foi plural na sua composiÃÃo: uso de autobiografias, narrativas ouvidas de interlocutores, periÃdicos, fotografias, letras de mÃsicas e poesias, como referente empÃrico produzido no recorte temporal em estudo. O resultado desse estudo se configurou na presenÃa de formas plurais de sociabilidade compondo o universo urbano de cidade de MacapÃ, dentre essas formas, o poder de forÃas de seus ocupantes parece dizer que foi e elemento norteador na conquista de viver à cidade. / The doutoramento thesis âA wharf that shelters life histories: men and machines constructing the social one in the city of Macapà (1943-1970)â is a study on the sociabilities that had given to form the existence in the city of MacapÃ. The narrative turns on the social interactions, nets and established sociotÃcnicas relations in the daily one of the process of gentrificaÃÃo of the City, in a period of predominance of the local power for the Nunes family in the TFA (1943-70). The laboratorial study it had in sight to apprehend as if it constructed the social one in the city of MacapÃ, when this City passed for social change in its urban structure. The sociability was the way for which I estimated the possible form of as to apprehend the collective constructions, that make possible the accomplishment or not of the singular or plural wills of the social life. Therefore, the experiment based on the boarding of the sociabilities and symmetrical associations, inhaled, in Simmel, amongst others arrives in port, theoretical conception that implied in the necessity to receive analytical categories as to be able, daily, social nets, sociotÃcnicas relations. The activity of field had as bedding the biographical sort, consisting of the modality life trajectory as concrete possibility of reconstruction of the past from stories, leading in account the occured discontinuity and ruptures in such a way in the level of the individual life as collective. Meantime, the examined material was plural in its composition: use of autobiografias, heard narratives of interlocutors, periodic, photographs, letters of musics and poetries, as referring empiricist produced in the secular clipping in study. The result of this study if configured in the presence of plural forms of sociability composing the urban universe of city of MacapÃ, amongst these forms, the power of forces of its occupants seems to say that it was and norteador element in the conquest of living to the city.
