Agent-based simulation of the learning dissemination on a Project-Based Learning context considering the human aspects

This work presents an agent-based simulation (ABS) of the active learning process in an Electrical Engineering course. In order to generate input data to the simulation, an active learning methodology developed especially for part-time degree courses, called Project-Based Learning Agile (PBLA), has been proposed and implemented at the Regional University of Blumenau (FURB), Brazil. Through the analysis of survey responses obtained over five consecutive semesters, using partial least squares path modeling (PLS-PM), it was possible to generate data parameters to use as an input in a hybrid kind of agent-based simulation known as PLS agent. The simulation of the scenario suggests that the learning occur faster when the student has higher levels of humanist's aspects as self-esteem, self-realization and cooperation.Comment: 8 pages, 6 figures, minor correction

Maintenance of shared spaces: courtyards of Tbilisi

Purpose The courtyard dwellings of Tbilisi form a critical part of the city’s architectural identity. However, the multiple occupation of these buildings is blamed for confounding their prospects for repair and consequent valorisation as a world heritage site. Models for the shared ownership of residential blocks, have been adapted globally. Some have established communal sources for rehabilitation and maintenance applicable to historic buildings. This paper assesses the relevance of such precedents to the complex and urgent context of Tbilisi’s threatened architectural heritage. Design/methodology/approach The paper uses existing literature and data to establish a hypothesis in support of adopting a collaborative approach for the maintenance and rehabilitation of shared buildings in a challenging and specific context. Using socio-economic data to characterise the occupants of such buildings and current critical sources, the paper investigates how existing collective communities can be empowered to capitalise from their unique social frameworks. Findings It finds evidence to support theoretical claims that there is scope for co-operative networks to flourish there. Originality/value This paper addresses a critical problem in the formulation of conservation plans for Old Tbilisi, it tests the relevance of global exemplars for community repair programmes by reference to existing data for the care of the predominantly domestic architecture of Old Tbilisi at a time of rapid change

HBIM and matching techniques: considerations for late nineteenth- and early twentieth-century buildings

Historic Building Information Modelling (HBIM) is limited by the irrelevance of object libraries and the inability of 3D scans to determine structures in buildings of dissimilar age and construction. The potential for energy conscious initiatives to make informed judgments regarding the ‘deep renovation’ of traditional buildings requires development of better non-invasive appraisal methods. Presumptions are dangerous for the majority of forms of historic building construction, yet older buildings benefit from better statutory control against alteration in any event. Here it is proposed that the pre-existing standard methods of nineteenth- and early twentieth-century construction could improve capacity to build data for a significant number of buildings of that era. The matching of images to develop place recognition algorithms has been deployed in a number of contexts. Standards, Patents and Specifications provide the means for developing new object libraries nested and shared from the surface to the structure. The example of decorative finishes, commonly used in public buildings at the turn of the twentieth century, demonstrates a traceable route whereby classifications could be determined using historic specifications and product data. The wider potential for such groundwork to enhance capacity to model energy performance of these less well protected buildings is suggested

Deconstructing the brain’s moral network: dissociable functionality between the temporoparietal junction and ventro-medial prefrontal cortex

Research has illustrated that the brain regions implicated in moral cognition comprise a robust and broadly distributed network. However, understanding how these brain regions interact and give rise to the complex interplay of cognitive processes underpinning human moral cognition is still in its infancy. We used functional magnetic resonance imaging to examine patterns of activation for ‘difficult’ and ‘easy’ moral decisions relative to matched non-moral comparators. This revealed an activation pattern consistent with a relative functional double dissociation between the temporoparietal junction (TPJ) and ventro-medial prefrontal cortex (vmPFC). Difficult moral decisions activated bilateral TPJ and deactivated the vmPFC and OFC. In contrast, easy moral decisions revealed patterns of activation in the vmPFC and deactivation in bilateral TPJ and dorsolateral PFC. Together these results suggest that moral cognition is a dynamic process implemented by a distributed network that involves interacting, yet functionally dissociable networks

Shared knowledge: The result of negotiation in non-hierarchical environments

The knowledge building can be seen as a collaborative process of which negotiation is a fundamental aspect. The use of technology to support this process has been attempted in various groupware systems. However, there is no adequate support system for the process of negotiation, which generally relies on voting as the element for reaching agreement in decision-making. On the other hand, the best approaches to this problem have been formalised in learning environments where there is a clear hierarchical structure. When the environment is not hierarchical, new problems arise which require special attention. This article presents a model of knowledge building that has negotiation as its basis in a group that is non-hierarchical in its structure. The model is implemented on a prototype tool named ShaKnoMa, which is tested on common tasks in an environment such as that proposed here. For the knowledge representation, concept maps are used which act a scaffolding to classify, index and search the information

Empathic concern drives costly altruism

Why do we self-sacrifice to help others in distress? Two competing theories have emerged, one suggesting that prosocial behavior is primarily motivated by feelings of empathic other-oriented concern, the other that we help mainly because we are egoistically focused on reducing our own discomfort. Here we explore the relationship between costly altruism and these two sub-processes of empathy, specifically drawing on the caregiving model to test the theory that trait empathic concern (e.g. general tendency to have sympathy for another) and trait personal distress (e.g. predisposition to experiencing aversive arousal states) may differentially drive altruistic behavior. We find that trait empathic concern – and not trait personal distress – motivates costly altruism, and this relationship is supported by activity in the ventral tegmental area, caudate and subgenual anterior cingulate, key regions for promoting social attachment and caregiving. Together, this data helps identify the behavioral and neural mechanisms motivating costly altruism, while demonstrating that individual differences in empathic concern-related brain responses can predict real prosocial choice

Remote lab experiments: opening possibilities for distance learning in engineering fields

Remote experimentation laboratories are systems based on real equipment, allowing students to perform practical work through a computer connected to the internet. In engineering fields lab activities play a fundamental role. Distance learning has not demonstrated good results in engineering fields because traditional lab activities cannot be covered by this paradigm. These activities can be set for one or for a group of students who work from different locations. All these configurations lead to considering a flexible model that covers all possibilities (for an individual or a group). An inter-continental network of remote laboratories supported by both European and Latin American institutions of higher education has been formed. In this network context, a learning collaborative model for students working from different locations has been defined. The first considerations are presented

How can century-old architectural hierarchies for the design of public libraries be re-interpreted and re-used?

Purpose The purpose of this paper is to describe a novel approach to inform heritage conservation based on the effective integration of documentation-based research with advanced survey methods for the creation of a sharable historic building information modelling (HBIM) objects database, specifically oriented to the study of Carnegie libraries whose designs in the USA and the UK were somewhat systematised by early principles of standardisation. The aim is to generate an exemplar developing new methodologies for the salvage, re-use and re-invigoration of shared inherited public buildings which have many common and standardized features. Design/methodology/approach This project will also involve the collaboration of conservation practice and digital recording together with library history. Digital laser scanning and structure from motion will be used together with archival documents to accurately build an information-rich framework for CAD and building information modelling applications. Findings By providing the base elements for the semi-automatic generation of a wide variety of morphological typologies and construction elements, this work ultimately promotes a shift towards the implementation of HBIM to support the conservation, maintenance and management of a high number of insufficiently protected public buildings from the turn of the last century. Originality/value The intention is that the resulting multidimensional parametric object library will provide suitable support for the faster generation of enriched 3D historic models and ultimately support the preservation of a large proportion of the huge but threatened public library building heritage in the UK and USA
