A diversificação das atividades e os produtos do turismo de base comunitária contribuem para aumentar o rendimento local. No contexto do desenvolvimento do turismo criativo no município de Lautém pode minimizar a pobreza e proporcionar experiências turísticas com base na comunidade em áreas rurais, através da criação de emprego de forma a responder às dificuldades econômicas e às necessidades da vida local neste município, em particular no posto-administrativo de Tutuala. Este estudo tem como objetivo, por um lado, compreender a importância da criatividade da comunidade na aplicação de experiências turísticas e, por outro lado, compreender a necessidade e a procura turística. De modo complementar, pretende-se dar a conhecer o papel da participação da comunidade como cocriadores no processo, para que se possa refletir sobre o conceito de turismo criativo como o método de desenvolvimento de transformação do destino, como um grande potencial de turismo de base comunitária nesta região. As técnicas de recolha de dados que se utilizam é a entrevista e a observação, ou seja, o método bola neve e a técnica de análise de dados sobre o conteúdo.

One hundred and ninety six researchers participated in the survey completing an on-line questionnaire. The questionnaire had three distinct sections, a classification of research domains, a classification of models, and an inquiry into software requirements for designing simulation platforms. The survey results allowed us to disambiguate the variety of scientific goals and modus operandi of researchers with a reasonable level of detail, and to identify a classification of agent-based models used in simulation. In particular, in the interdisciplinary context of social-scientific modelling, agentbased computational modelling and computer engineering, we analyse the extent to which these paradigmatic models seem to be mutually instrumental in the field. We expect that our proposal may improve the viability of submitting, explaining and comparing agent-based simulations in articles, which is an important methodological requirement to consolidate the field. We also expect that it will motivate other proposals that could further validate, extend or change ours, in order to refine the classification with more types of models.

It details several parameter sweeps and experiments done to characterise an agent-based model created for the purpose of exploring the role of communication strategies and topology in determining the transformation of cultural systems. It characterises systems in terms of the stantardised entropy (HRel) of "local prototypes" (LP) - here understood as vectors of probabilities of interpretation of certain categories - as well as the convergence of these LP to the "Global Prototypes" (GP), using a simple ratio of the two Hrel (CL).

This short paper introduces a hypothesis complementary to the current logic of replicating computerized models in social simulations. It is submitted that the logic of cumulative knowledge provided by the process of peer reviewing may become more resourceful once the effort of replication becomes focused on producing multiple computerized versions of the same conceptual model before actually submitting it for peer reviewing, in contrast to the usual practice of having other teams aligning and replicating models after they have already been reviewed, accepted and published. Note that while this is a similar approach to Edmonds and Hales ’ proposal, it differs from a methodological point of view, insofar as they double replicated an already published model. While this approach would require more manpower in simulation projects, it is argued here that the resulting benefits may override the costs, particularly in participative-based simulations, where potential underverified ...

Our claim is that any social principle prescribed within a level of abstraction above Newell's Knowledge Level, in order to balance the needs of the individual and the system as a whole, can not adopt an utility-oriented scale of performance but instead must adopt a substantialist-oriented (goaldriven) concept of performance. On this perspective, we propose a number of goal-generating principles for social responsible agents, towards an uncompromising individualistic view of autonomous agents that nevertheless attempt to motivate the welfare of collectives.

We give the following contributions: (i) aid the identification of general principles to develop platforms; (ii) advance the analysis and prospection of technical-operational and highlevel requirements; (iii) promote the identification of shared requirements, addressing them to the development of an integrated work. We present our reference model and make a comparative analysis between three well-known platforms, resulting in an unambiguous and schematic characterisation of computational systems for agent-based simulation.

The data is made available raw or by department listing and does not provide the network of co-authorships that implicitly emerges from scientific collaborations among different departments. Sometimes, the network of co-authorships is computed within the institution, via standalone applications that have few or no functionalities to explore the structure of collaborations. The possibility of searching online and managing the network of scientific communities in the institution is a matter of management efficiency, both for the institution itself and other external collaborators. This paper explains a distributed architecture and a tool that uses data from an online institutional repository. The tool calculates and puts available online the co-authorship network that identifies research communities according to different algorithms. The tool reflects and identifies the emergent structure of communities, graphically analyses communities, exports, reports and follows up with the evolution of communities in time.

To help you decide how to check your simulation – both against its antecedent conceptual models (verification) and external standards such as data (validation) – and in this way help you to establish the credibility of your simulation. In order to do this the chapter will point out the nature of these processes, including the variety of ways in which people seek to achieve them. Abstract Verification and validation are two important aspects of model building. Verification and validation compare models with observations and descriptions of the problem modelled, which may include other models that have been verified and validated to some level. However, the use of simulation for modelling social complexity is very diverse. Often, verification and validation do not refer to an explicit stage in the simulation development process, but to the modelling process itself, according to good practices and in a way that grants credibility to using the simulation for a spe...

Verification and validation compare models with observations and descriptions of the problem modelled, which may include other models that have been verified and validated to some level. However, the use of simulation for modelling social complexity is very diverse. Often, verification and validation do not refer to an explicit stage in the simulation development process, but to the modelling process itself, according to good practices and in a way that grants credibility to using the simulation for a specific purpose. One cannot consider verification and validation without considering the purpose of the simulation. This chapter deals with a comprehensive outline of methodological perspectives and practical uses of verification and validation. The problem of evaluating simulations is addressed in four main topics: (1) the meaning of the terms verification and validation in the context of simulating social compl...

The experimental reference of simulation remains ambiguous, insofar as the logic of its method turns computer programs into something more than a tool in the social sciences, defining them as the experimental subject itself. The goal of this paper is to construct a methodological perspective that is able to conciliate the formal and empirical logic of program verification in computer science, with the interpretative and multiparadigmatic logic of the social sciences. This is a condensed and revised version of David et al. (2006). We demonstrate that the method of simulation implies at least two distinct types of program verifications, which we call empirical and intentional verification. Furthermore, we clarify the experimental reference of simulation by demonstrating that the process of intentional verification is contingent upon both the behaviors of the programs and the observed social phenomena.

An intensity that makes the teaching of electronic marketing somewhat challenging and specific when compared with other disciplines. Teaching electronic marketing will only be effective if the learning environment reaches similar levels of technological intensity as the discipline itself. This suggests that electronic marketing might be particularly appropriate to the use of e-learning as a teaching instructional model. However, this carries risks and further challenges, resulting from difficulties in obtaining positive results whenever learning is supported by e-learning platforms. If one wants to achieve lower failure risks and effective and motivated learning, the e-learning model should be provided with features that strengthen it pedagogically. This paper proposes a practice field for teaching electronic marketing, embedded and tested in an e-learning platform provided with learning activities that implement a practice field.

The design of learning activities through mediating tools (MTs) moderates this difficulty, allowing the adaptation of instructional designs so they are pedagogically appropriate to the learning outcomes. Nevertheless, the provision of methods and empirical results to help design activities and properly organise them in MTs remains a challenge. In this paper, we propose a pattern of alignment among learning outcomes, learning activities and MTs that facilitates instructional design, using pedagogical principles based on Bloom's taxonomy and problem-based learning (PBL). A framework is provided to classify, model and implement teacher-centred content into organised student-centred activities that are clustered in MTs with higher-order learning capabilities. This approach can lead to the development of a consistent instructional design, which is susceptible to evaluation, thus making it possible to test further alignments among the obtained results, the intended design characteristics and the pedagogical principles. The results confirm that high levels of Bloom's taxonomy are achieved, particularly with respect to the requirements of learning model centricity and collaborative learning.

Deste âmbito, a presente investigação pretende identificar os indicadores que podem contribuir para a adoção das políticas do Estado para mitigar a emigração de camada jovens em Timor-Leste em relação das causas e seus impactos socioeconómicos no seio da sociedade timorense. Com aproximação ao método qualitativo, recolhemos as informações através da realização de entrevistas não estruturada face às entidades públicas, líderes políticos e religiosos, sociedade civil, e aos familiares de emigrantes que partilharam os seus conhecimentos sobre os assuntos de investigação em causa. Neste caso, utilizando-se neste processo a análise conteúdo e QDA Miner.
Os resultados apresentam que o destino de emigração de camadas jovens emigrantes de Timor-Leste é Reino Unido e a Irlanda do Norte. As bases que fomentam a escolher esses países de destino variam-se pelos diversos indicadores fundamentais. Os fatores que influência os jovens à emigrarem são: questões económicas causadas pela pobreza e fatores sociais como desempregados, educação, cultura e tecnologia. As causas da emigração de jovens são as ofertas do trabalho para os trabalhadores com menos habilidades (skills), problemas de economia e social e das deceções e pressões psicológicas.
O impacto socioeconómico dos emigrantes na sociedade timorense tem vindo para contribuir a diminuição de desempregos no país, também para obterem as novas experiências de trabalho, para a melhoria da economia familiar, para além disso tenham ainda os seus impactos negativos como perde da idade produtiva do trabalho e da melhoria económica no desenvolvimento das indústrias com facilidades modernas dos países recetores.
A política de consenso nacional acerca da diversificação económica e do investimento no setor produtivo, a criação do campo de trabalho, o desenvolvimento do setor da educação e técnico profissional, considerando-se neste sentido através da cooperação com o Reino Unido da Inglaterra e da Irlanda do Norte, vimo-nos como maiores vantagens e prioridades que, deveríamos articular e ao agregá-las de forma deliberada como as políticas do Estado alvos para o desenvolvimento da criação de novas oportunidades, dando conta, para mitigar a emigração de camadas jovens em Timor-Leste.
