Effectiveness of online corporate collaborative teams

With this article we intend to contribute to the understanding of what can make Online Collaborative Teams (OCT) effective. This is done by identifying what can be considered best practices for individual team members, for leaders of OCT, and for the organizations that the teams are a part of. Best practices in these categories were identified from the existing literature related to online teams and collaborative work literature.

Personality, emotion, and mood in agent-based group decision making

Group decision making plays an important role in organizations, especially in the present-day economy that demands high-quality, yet quick decisions. Group decision-support systems (GDSSs) are interactive computer-based environments that support concerted, coordinated team efforts toward the completion of joint tasks. The need for collaborative work in organizations has led to the development of a set of general collaborative computer-supported technologies and specific GDSSs that support distributed groups (in time and space) in various domains. However, each person is unique and has different reactions to various arguments. Many times a disagreement arises because of the way we began arguing, not because of the content itself. Nevertheless, emotion, mood, and personality factors have not yet been addressed in GDSSs, despite how strongly they influence results. Our group’s previous work considered the roles that emotion and mood play in decision making. In this article, we reformulate these factors and include personality as well. Thus, this work incorporates personality, emotion, and mood in the negotiation process of an argumentbased group decision-making process. Our main goal in this work is to improve the negotiation process through argumentation using the affective characteristics of the involved participants. Each participant agent represents a group decision member. This representation lets us simulate people with different personalities. The discussion process between group members (agents) is made through the exchange of persuasive arguments. Although our multiagent architecture model4 includes two types of agents—the facilitator and the participant— this article focuses on the emotional, personality, and argumentation components of the participant agent.

Notas sobre o mundo social do livro: a construção do editor e da edição

Personagem-filtro, intérprete, mas também interventor, prescrevendo, legitimando e ordenando o universo tipográfico, o editor surge como figura múltipla e socialmente investida de atributos e práticas mediadoras na sua relação com o dado textual. Produtor de valor e materialidade, o editor inscreve o projecto do livro num espaço social colaborativo de trabalho, o campo da edição. Este artigo procura sistematizar teoricamente alguns tópicos relativos à articulação do editor com a construção social do campo editorial e a edificação da cultura impressa. Empreender semelhante exploração é abdicar forçosamente de uma visão linear, unidimensional e historicamente asséptica do mundo social e cultural do livro, cuja morfologia e suportes conhecem crescentemente os desafios da desmaterialização.

Pluralidade, mudança e produção de valor na edição de livros: notas sobre a edificação social da cultura impressa

Habitando um campo de intermediação, filtragem e interpretação, o editor assume um papel de legitimação, ordenação e prescrição do mundo pela via tipográfica. O esforço de realização de um livro não se restringe à génese autoral do texto. O livro resulta de um trabalho que implica acrescento simbólico e viabilidade de circulação, sem os quais o objecto se perde enquanto objecto de desejo, factor de aval de conteúdos ou elemento de alarde identitário. A existência de um livro corresponde em grande parte à acção editorial de o instituir socialmente como obra conhecida e reconhecida pelos seus receptores finais. Produtor de valor e materialidade, o editor inscreve o projecto do livro num espaço social colaborativo de trabalho, o campo da edição. Esta apresentação procura sistematizar teoricamente alguns tópicos relativos à articulação do editor com a construção social do campo editorial e a edificação da cultura impressa. Empreender semelhante exploração é abdicar forçosamente de uma visão linear, unidimensional e a-histórica do mundo social e cultural do livro, cuja morfologia e suportes conhecem crescentemente os desafios da desmaterialização.

VirtualECare: group support in collaborative networks organizations for digital homecare

Collaborative Work plays an important role in today’s organizations, especially in areas where decisions must be made. However, any decision that involves a collective or group of decision makers is, by itself complex, but is becoming recurrent in recent years. In this work we present the VirtualECare project, an intelligent multi-agent system able to monitor, interact and serve its customers, which are, normally, in need of care services. In last year’s there has been a substantially increase on the number of people needed of intensive care, especially among the elderly, a phenomenon that is related to population ageing. However, this is becoming not exclusive of the elderly, as diseases like obesity, diabetes and blood pressure have been increasing among young adults. This is a new reality that needs to be dealt by the health sector, particularly by the public one. Given this scenarios, the importance of finding new and cost effective ways for health care delivery are of particular importance, especially when we believe they should not to be removed from their natural “habitat”. Following this line of thinking, the VirtualECare project will be presented, like similar ones that preceded it. Recently we have also assisted to a growing interest in combining the advances in information society - computing, telecommunications and presentation – in order to create Group Decision Support Systems (GDSS). Indeed, the new economy, along with increased competition in today’s complex business environments, takes the companies to seek complementarities in order to increase competitiveness and reduce risks. Under these scenarios, planning takes a major role in a company life. However, effective planning depends on the generation and analysis of ideas (innovative or not) and, as a result, the idea generation and management processes are crucial. Our objective is to apply the above presented GDSS to a new area. We believe that the use of GDSS in the healthcare arena will allow professionals to achieve better results in the analysis of one’s Electronically Clinical Profile (ECP). This achievement is vital, regarding the explosion of knowledge and skills, together with the need to use limited resources and get better results.

Collaborative learning in a qeb-accessible workbench

Web-based course management and delivery is regarded by many institutions as a key factor in an increasingly competitive education and training world, but the systems currently available are largely unsatisfactory in terms of supporting collaborative work and access to practical science facilities. These limitations are less important in areas where “pen-and-paper” courseware is the mainstream, but become unacceptably restrictive when student assignments require real-time teamwork and access to laboratory equipment. This paper presents a web-accessible workbench for electronics design and test, which was developed in the scope of an European IST project entitled PEARL, with the aim of supporting two main features: full web access and collaborative learning facilities.

Key cognitive and collaborative aptitudes in ambulance people

The aim of our study was to identify and document some key cognitive aptitudes used by ambulance people in emergency situations. Better knowing such aptitudes is necessary for a school of ambulance people in order to improve the selection and education of students. The idea was to better consider real work activity requirements and characteristics, and to develop and implement genuine educational content and selection tools. We followed the work activity of ambulance professionals involved in real emergency situations. Some interventions were filmed and post-analyzed. We completed and validated our analysis by means of interviews with ambulance personnel. We selected some video sequences and used them as a support for the interviews. We identified and documented many different key aptitudes like orientation and spatial sense, the capacity to perform complex cognitive tasks and delicate manipulations in the context of divided attention, as well as diverse aptitudes relevant in collaborative work.

Teaching how to learn with a wiki in Primary Education: what classroom interaction can tell us

Understanding how wikis are used to support collaborative learning is an important concern for researchers and teachers. Adopting a discourse analytic approach, this paper attempts to understand the teaching processes when a wiki is embedded in a science project in primary education to foster collaborative learning. Through studying interaction between the teacher and students, our findings identify ways in which the teacher prompts collaborative learning but also shed light on the difficulties for the teacher in supporting student collective collaboration. It is argued that technological wiki features supporting collaborative learning can only be realized if teacher talk and pedagogy are aligned with the characteristics of wiki collaborative work: the freedom of students to organize and participate by themselves, creating dialogic space and promoting student participation. We argue that a dialogic approach for examining interaction can be used to help to design a more effective pedagogic approach in the use of wikis in education, to shift into Web 2.0 learning paradigm and to equip learners with the competences they need to participate in knowledge co-construction.

Collaborative design procedures for architects and engineers

This book argues for novel strategies to integrate engineering design procedures and structural analysis data into architectural design. Algorithmic procedures that recently migrated into the architectural practice are utilized to improve the interface of both disciplines. Architectural design is predominately conducted as a negotiation process of various factors but often lacks rigor and data structures to link it to quantitative procedures. Numerical structural design on the other hand could act as a role model for handling data and robust optimization but it often lacks the complexity of architectural design. The goal of this research is to bring together robust methods from structural design and complex dependency networks from architectural design processes. The book presents three case studies of tools and methods that are developed to exemplify, analyze and evaluate a collaborative work flow.

Formação em contexto, revitalizadora de aprendizagens pessoais, profissionais e organizacionais

Muito se tem teorizado sobre a formação contínua dos professores e a sua implicação no desenvolvimento pessoal e profissional dos docentes, tendo sempre presente as necessárias melhorias no sistema educativo. Entre a dimensão teórica que nos reconforta pela quantidade de saberes acumulados ao longo dos anos e a dimensão prática que se esvanece frequentemente na inércia e rotinas diárias dos professores fica a ausência de uma formação contínua adequada às verdadeiras necessidades dos seus profissionais. Falta proporcionar o encontro mais sistemático entre teoria e prática em contexto, ou vice-versa, numa simbiose perfeita de sentidos para que a formação se torne essencial e determinante na prática diária do professor. A reflexão e o profundo questionamento sobre esta temática colocaram-nos diante de uma questão extremamente pertinente: que formação contínua em contexto proporcionar aos docentes, promotora de aprendizagens (pessoais, profissionais, organizacionais) e da melhoria dos resultados escolares num Agrupamento de Escolas? As respostas estão implícitas na formulação do tema do presente trabalho: (i) a formação em contexto permite revitalizar aprendizagens pessoais, profissionais e organizacionais; (ii) (re)pensar e (re)dinamizar as dinâmicas de trabalho entre professores, bem como criar novas dinâmicas organizacionais, procurando desenvolver saberes e competências individuais que devidamente aproveitados farão da escola um espaço de trabalho agradável, onde a partilha, o trabalho colaborativo e reflexivo melhorarão naturalmente as práticas do quotidiano escolar. Efetuou-se um levantamento das ações realizadas pelos docentes do agrupamento e verificou-se que maioritariamente se faziam fora do âmbito disciplinar, constrangimento apontado pela falta de formações específicas nas áreas disciplinares. Esta e outras questões foram validadas a partir das entrevistas semiestruturadas realizadas a docentes do agrupamento que confirmaram existir no contexto escolar oportunidades de aprendizagem desaproveitadas. Partindo das fundamentações necessárias, quer a partir dos dados, quer a partir de um quadro concetual teórico, quer ainda da opinião muito favorável das professoras entrevistadas, propomos um projeto de formação pró-ativo concebido para um agrupamento de escolas que contribua para a melhoria das práticas letivas.

A tool for replay and analysis of gaze-enhanced multiparty sessions captured in immersive collaborative environments

A desktop tool for replay and analysis of gaze-enhanced multiparty virtual collaborative sessions is described. We linked three CAVE (TM)-like environments, creating a multiparty collaborative virtual space where avatars are animated with 3D gaze as well as head and hand motions in real time. Log files are recorded for subsequent playback and analysis Using the proposed software tool. During replaying the user can rotate the viewpoint and navigate in the simulated 3D scene. The playback mechanism relies on multiple distributed log files captured at every site. This structure enables an observer to experience latencies of movement and information transfer for every site as this is important fir conversation analysis. Playback uses an event-replay algorithm, modified to allow fast traversal of the scene by selective rendering of nodes, and to simulate fast random access. The tool's is analysis module can show each participant's 3D gaze points and areas where gaze has been concentrated.

Model-based groupware solution for distributed real-time collaborative 4D planning via teamwork

Construction planning plays a fundamental role in construction project management that requires team working among planners from a diverse range of disciplines and in geographically dispersed working situations. Model-based four-dimensional (4D) computer-aided design (CAD) groupware, though considered a possible approach to supporting collaborative planning, is still short of effective collaborative mechanisms for teamwork due to methodological, technological and social challenges. Targeting this problem, this paper proposes a model-based groupware solution to enable a group of multidisciplinary planners to perform real-time collaborative 4D planning across the Internet. In the light of the interactive definition method, and its computer-supported collaborative work (CSCW) design analysis, the paper discusses the realization of interactive collaborative mechanisms from software architecture, application mode, and data exchange protocol. These mechanisms have been integrated into a groupware solution, which was validated by a planning team in a truly geographically dispersed condition. Analysis of the validation results revealed that the proposed solution is feasible for real-time collaborative 4D planning to gain a robust construction plan through collaborative teamwork. The realization of this solution triggers further considerations about its enhancement for wider groupware applications.

Characterising the use of urban space: a geochemical case study from Calleva Atrebatum (Silchester, Hampshire, UK) Insula IX during the late first/early second century AD

The geochemical analysis of soil samples from the Roman town of Calleva Atrebatum (Silchester, Hampshire, UK) has been undertaken in order to enhance our understanding of urban occupation during the late first/early second century AD. Samples taken from a variety of occupation deposits within several, contemporary timber buildings, including associated hearths, have been analysed using laboratory-based x-ray fluorescence for a suite of elements (Cu, Zn, Pb, Sr, P and Ca). The patterns of elemental enrichment seen across the site have allowed us to compare and contrast the buildings that were occupied during this time in an attempt to distinguish different uses, such as between domestic and work-space. Two of the buildings stand out as having high concentrations of elements which suggest that they were dirtier work spaces, whilst other buildings appear to be have lower chemical loadings suggesting they were cleaner.

Posicionamento e movimentação de um robô humanóide utilizando imagens de uma câmera móvel externa

This work proposes a method to localize a simple humanoid robot, without embedded sensors, using images taken from an extern camera and image processing techniques. Once the robot is localized relative to the camera, supposing we know the position of the camera relative to the world, we can compute the position of the robot relative to the world. To make the camera move in the work space, we will use another mobile robot with wheels, which has a precise locating system, and will place the camera on it. Once the humanoid is localized in the work space, we can take the necessary actions to move it. Simultaneously, we will move the camera robot, so it will take good images of the humanoid. The mainly contributions of this work are: the idea of using another mobile robot to aid the navigation of a humanoid robot without and advanced embedded electronics; chosing of the intrinsic and extrinsic calibration methods appropriated to the task, especially in the real time part; and the collaborative algorithm of simultaneous navigation of the robots
