A web-based teaching/learning environment to support collaborative knowledge construction in design

A web-based application has been developed as part of a recently completed research which proposed a conceptual framework to collect, analyze and compare different design experiences and to construct structured representations of the emerging knowledge in digital architectural design. The paper introduces the theoretical and practical development of this application as a teaching/learning environment which has significantly contributed to the development and testing of the ideas developed throughout the research. Later in the paper, the application of BLIP in two experimental (design) workshops is reported and evaluated according to the extent to which the application facilitates generation, modification and utilization of design knowledge

Assessing architectural evolution: A case study

This is the post-print version of the Article. The official published can be accessed from the link below - Copyright @ 2011 SpringerThis paper proposes to use a historical perspective on generic laws, principles, and guidelines, like Lehman’s software evolution laws and Martin’s design principles, in order to achieve a multi-faceted process and structural assessment of a system’s architectural evolution. We present a simple structural model with associated historical metrics and visualizations that could form part of an architect’s dashboard. We perform such an assessment for the Eclipse SDK, as a case study of a large, complex, and long-lived system for which sustained effective architectural evolution is paramount. The twofold aim of checking generic principles on a well-know system is, on the one hand, to see whether there are certain lessons that could be learned for best practice of architectural evolution, and on the other hand to get more insights about the applicability of such principles. We find that while the Eclipse SDK does follow several of the laws and principles, there are some deviations, and we discuss areas of architectural improvement and limitations of the assessment approach

Towards guidelines for building a business case and gathering evidence of software reference architectures in industry

Background: Software reference architectures are becoming widely adopted by organizations that need to support the design and maintenance of software applications of a shared domain. For organizations that plan to adopt this architecture-centric approach, it becomes fundamental to know the return on investment and to understand how software reference architectures are designed, maintained, and used. Unfortunately, there is little evidence-based support to help organizations with these challenges. Methods: We have conducted action research in an industry-academia collaboration between the GESSI research group and everis, a multinational IT consulting firm based in Spain. Results: The results from such collaboration are being packaged in order to create guidelines that could be used in similar contexts as the one of everis. The main result of this paper is the construction of empirically-grounded guidelines that support organizations to decide on the adoption of software reference architectures and to gather evidence to improve RA-related practices. Conclusions: The created guidelines could be used by other organizations outside of our industry-academia collaboration. With this goal in mind, we describe the guidelines in detail for their use.Peer ReviewedPostprint (published version

A dependency network description of building information models

The pervasive deployment of “smart building” projects world-wide is driving innovation on many fronts including; technology, telematics, engineering and entrepreneurship. This paper focuses on the technical and engineering perspectives of BIM, by extending building morphology studies as to respond to the challenges posed by Big Data, and smart infrastructure. The proposed framework incorporates theoretical and modelling descriptions to verify how network-based models can act as the backbone skeletal representation of building complexity, and yet relate to environmental performance and smart infrastructure. The paper provides some empirical basis to support data information models through building dependency networks as to represent the relationships between different existing and smart infrastructure components. These dependency networks are thought to inform decisions on how to represent building data sets in response to different social and environmental performance requirements, feeding that into void and solid descriptions of data maturity models. It is concluded that network-based models are fundamental to comprehend and represent the complexity of buildings and inform architectural design and public policy practices, in the design and operation phases of infrastructure projects

Turning points or turning around: Family coach work with 'troubled families'

The study aimed to discover how family coaches work intensively with families with moderately complex problems bringing together perceptions from 20 families, 20 coaches and six other professionals, and exploring potential savings for 50 family cases. The Family Coaching Service is part of the English government’s ‘Troubled Families’ payment by results initiative, seeking to help families ‘turn their lives around’ to save state spending on anti-social behaviour, worklessness and school absence. Results show the work to be a staged process, over six months with the coach combining practical help with relationship building to engage families, set and achieve goals and negotiate endings. Cost savings were made in 82% of cases. Family coaches find the work rewarding but emotionally demanding. Families say their coach is special and different, and describe potential turning point experiences stemming from the work with their coach. There is clear congruence in the perceptions of the service from families, coaches and other professionals. Some tensions were evident in the work with other professionals and in managing relationship boundaries with families. Relationship-based help offered by para-professionals may offer a promising model of family support that statutory social workers in particular can learn from and engage with

Dyadic Relationship Scale: A Measure of the Impact of the Provision and Receipt of Family Care

Purpose: This study evaluated the psychometric properties of the Dyadic Relationship Scale (DRS), which measures negative and positive dyadic interactions from the perspective of both the patient and the family caregiver. An important aspect of evaluating the DRS was that it be statistically sound and meaningful for both members of the dyad. Design and Methods: The study used a cross-sectional design. Survey packages were mailed to home health care patients and their family caregivers. The unit of analysis was the dyad, and exploratory and confirmatory factor analyses were conducted. We examined the reliability, discriminant, and concurrent validities of the instrument. Results: The data supported a two-factor DRS that included negative dyadic strain (patient α = .84; caregiver α = .89) and positive dyadic interaction (patient α = .86; caregiver α = .85). The analysis supported the DRS\u27s construct, discriminant, and concurrent validity, as well as its reliability for both patients and family caregivers. Implications: Using the DRS to measure the impact of family care on positive and negative interactions inclusive of patients and caregivers can assist in identifying areas of difficulty and guide interventions to improve outcomes for both members of the dyad
