An intelligent content discovery technique for health portal content management

Background: Continuous content management of health information portals is a feature vital for its sustainability and widespread acceptance. Knowledge and experience of a domain expert is essential for content management in the health domain. The rate of generation of online health resources is exponential and thereby manual examination for relevance to a specific topic and audience is a formidable challenge for domain experts. Intelligent content discovery for effective content management is a less researched topic. An existing expert-endorsed content repository can provide the necessary leverage to automatically identify relevant resources and evaluate qualitative metrics.Objective: This paper reports on the design research towards an intelligent technique for automated content discovery and ranking for health information portals. The proposed technique aims to improve efficiency of the current mostly manual process of portal content management by utilising an existing expert-endorsed content repository as a supporting base and a benchmark to evaluate the suitability of new contentMethods: A model for content management was established based on a field study of potential users. The proposed technique is integral to this content management model and executes in several phases (ie, query construction, content search, text analytics and fuzzy multi-criteria ranking). The construction of multi-dimensional search queries with input from Wordnet, the use of multi-word and single-word terms as representative semantics for text analytics and the use of fuzzy multi-criteria ranking for subjective evaluation of quality metrics are original contributions reported in this paper.Results: The feasibility of the proposed technique was examined with experiments conducted on an actual health information portal, the BCKOnline portal. Both intermediary and final results generated by the technique are presented in the paper and these help to establish benefits of the technique and its contribution towards effective content management.Conclusions: The prevalence of large numbers of online health resources is a key obstacle for domain experts involved in content management of health information portals and websites. The proposed technique has proven successful at search and identification of resources and the measurement of their relevance. It can be used to support the domain expert in content management and thereby ensure the health portal is up-to-date and current.

Designing a responsive material system with physical computing

This paper focuses on an investigation to explore architectural design potentials with a responsive material system and physical computing. Contemporary architects and designers are seeking to integrate physical computing in responsive architectural designs; however, they have largely borrowed from engineering technology's mechanical devices and components. There is the opportunity to investigate an unexplored design approach to exploit the responsive capacity of material properties as alternatives to the current focus on mechanical components and discrete sensing devices. This opportunity creates a different design paradigm for responsive architecture that investigates the potential to integrate physical computing with responsive materials as one integrated material system. Instead of adopting highly intricate and expensive materials, this approach is explored through accessible and off-the-shelf materials to form a responsive material system, called Lumina. Lumina is implemented as an architectural installation called Cloud that serves as a morphing architectural skin. Cloud is a proof of concept to embody a responsive material system with physical computing to create a reciprocal and luminous architectural intervention for a selected dark corridor. It represents a different design paradigm for responsive architecture through alternative exploitation of contemporary materials and parametric design tools. © 2014, The Association for Computer-Aided Architectural Design Research in Asia (CAADRIA), Hong Kong.

Assessment might dictate the curriculum, but what dictates assessment?

Almost all tertiary educators make assessment choices, for example, when they create an assessment task, design a rubric, or write multiple-choice items. Educators potentially have access to a variety of evidence and materials regarding good assessment practice but may not choose to consult them or be successful in translating these into practice. In this article, we propose a new challenge for the Scholarship of Teaching and Learning: the need to study the disjunction between proposals for assessment “best practice” and assessment in practice by examining the assessment decision-making of teachers. We suggest that assessment decision-making involves almost all university teachers, occurs at multiple levels, and is influenced by expertise, trust, culture, and policy. Assessment may dictate the curriculum from the student’s perspective, and we argue that assessment decision-making dictates assessment.

Towards a BIM-based energy rating system

Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria. © 2014, The Association for Computer-Aided Architectural Design Research in Asia (CAADRIA), Hong Kong.

A case study on developing a teacher's capacity in mathematical modelling

Research has indicated that for teachers to facilitate mathematical modelling activities in the mathematics classroom, they need to be familiar with the process of mathematical modelling. As such, it is imperative that teachers experience the whole mathematical modelling process. This paper reports on a Multi-tiered Teaching Experiment designed to help a teacher develop his capacity in the domain of mathematical modelling. Drawing on part of a larger case-based study conducted using Design Research phases situated within the Multi-tiered Teaching Experiment framework, the purpose of this paper is to exemplify how the research design fostered growth in teacher capacity through the natural development of critical moments of learning by the teacher during interactions between the researchers and the teacher-modeller himself. The potential of the Multi-tiered Teaching Experiment as a useful non-prescriptive teacher development approach building upon the existing repertoire of individual teachers will be discussed.

Developing teacher competencies through videos for facilitation of mathematical modelling in Singapore primary schools

Mathematical modelling tasks which are situated in real-world contexts encourage students to draw connections between school-based mathematics and the real-world, enhancing their engagement in learning. Such tasks often require varied interpretations of the real-world problem context resulting in multiple pathways of solutions. Although mathematical modelling has been introduced in the Singapore mathematics curriculum since 2007, its incorporation in schools has been limited. One reason for this could be that teachers are challenged by how best to facilitate for rich student mathematisation processes during such tasks. This chapter reports how a multi-tiered teaching experiment using design research methodology was conducted to build teachers’ capacity in designing, facilitating, and evaluating student mathematisation during mathematical modelling tasks with an intact class of Primary 5 students (aged 10-11). The use of videos was critical because grounded images helped capture the dynamics and complexity of authentic classroom interactions. This chapter highlights how video recordings of teacher-student interactions during a modelling task were harnessed during design methodology cycles, particularly during the Retrospective Analysis phase, to activate critical moments of learning for the teacher towards developing her competencies in facilitating students’ mathematisation processes.

Painterface: an integrated responsive architectural interface

Interface design is one of the main research areas in human-computer interaction (HCI). In computer science, many HCI re-searchers and designers explore novel interface designs with cutting-edge technology, but few investigate alternative interfaces for existing built environments, especially in the area of architecture. In this pa-per, we investigate alternative interface designs for existing architectural elements—such as walls, floors, and ceilings—that can be created with off-the-shelf materials. Instead of merely serving as discrete sensing and display devices integrated to an existing building’s surface, these liquid and thin materials act as interventions that can be ‘painted’ on a surface, transforming it into an architectural interface. This interface, Painterface, is a responsive material intervention that serves as an analogue, wall-type media interface that senses and responds to people’s actions. Painterface is equipped with three sensing and responsive capacities: touch, sound, and light. While the inter-face’s touch capacity performs tactile sensing, its sound-production and illumination capacities emit notes and light respectively. The out-comes of this research suggest the possibility of a simple, inexpensive, replaceable, and even disposable interface that could serve as an architectural intervention applicable to existing building surfaces.

Typography and the branding of culture: a methodological investigation into the way typography is used to brand cultural festivals in Australia

The observance of and participation in festivals and celebratory events is an increasingly significant aspect of the contemporary experience (Picard & Robinson, 2006). With the prestige that comes from holding culturally relevant and socially acceptable festivals that serve the discourses of “city branding” and the “creative industries” in a competitive global context; significant government, community and private funding is allocated to such events. Festivals have become a central figure of not only the political economy of tourism but also of urban regeneration and cultural tourism. Cultural festivals possess the hallmarks of destination branding or place branding and inadvertently share some of the attributes that influence visitors’ decisions to visit such destinations (Blain, Levy, & Ritchie, 2005; Cooper, 2005; Esu & Arrey, 2009; Jayswal, 2008). Branding is a vital part of this festival space and relies on typography to establish the symbolic values and representations of urban freedoms; rich histories, cultured places, playfulness and stimulation that seek to subvert our daily existence while performing the task of engaging local, national, and international visitors and participants. However, professional practices demonstrated in the design, media and arts industries have far outpaced the extent to which this phenomenon has been written about in the academic or public realm. What this paper intends is to interrogate appropriate semiotic approaches in an effort to analysing the discursive practices of typography as it performs in service to branding cultural festivals in Australia. The intention is to establish a methodology suited to the significant role typography performs within this context and to offer a contribution to design research that not only engages with the artefacts of design but with the conceptualization of designed meaning in 21st century visual culture.

Typography and the branding of culture: a systemic functional analysis of typography’s performance in branding cultural festivals in Australia

This paper offers a social semiotic analysis of logotypes used to brand cultural festivals in 21st century Australia. A contemporary method is explored that suits the significant role typography performs within this context and offers a contribution to design research and the festival scape that not only engages with the artefacts of design but with the conceptualization of designed meaning in visual culture. Branding is a vital part of the festival space and relies on typography to establish the symbolic values and representations of urban freedoms; rich histories, cultured places, playfulness and stimulation that seek to subvert our daily existence while performing the task of engaging local, national, and international visitors and participants. However, professional practices demonstrated in the design, media and arts industries have far outpaced the extent to which this phenomenon has been written about in the academic or public realm. This paper addresses this shortfall and offers the foundation for a systemic functional method in the decoding of typography in visual culture

Problems experienced by students on field placement: using research findings to inform curriculum design and content

Recent recognition of workplace learning from within the University sector has resulted in more emphasis being placed on including field experiences in course curriculum across a range of disciplines. This article begins with a short review of the literature relating to the current context in which work-based learning occurs. Next, selected findings from a survey of 39 Victorian social work students on their experiences of placement learning are reported. The survey focused on problems encountered by students on placement. A number of the problems students faced suggested the need for additional opportunities both before and during the placements to engage with material on safety in the field, and ways to deal with workplace stress and conflict. In response to these issues the article summarises some pedagogical strategies that may be used to enhance student learning in these areas both leading up to and during their field placements. In addition to matters relating to safety and stress, financial pressures were evident for students endeavouring to complete field placements. The recent moves from universities to embrace industry based learning, clearly has implications for funding support made available to students undertaking this type of education.

Design, format, validity and reliability of mutiple choice questions for use in nursing research and education

Multiple choice questions are used extensively in nursing research and education and play a fundamental role in the design of research studies or educational programs. Despite their widespread use, there is a lack of evidence-based guidelines relating to design and use of multiple choice questions. Little is written about their format, structure, validity and reliability of in the context of nursing research and/or education and most of the current literature in this area is based on opinion or consensus. Systematic multiple choice question design and use of valid and reliable multiple choice questions are vital if the results of research or educational testing are to be considered valid. Content and face validity schould be established by expert panel review and construct validity should be established using ‘key check’, item discrimination and item difficulty analyses. Reliability measures include internal consistency and equivalence. Internal consistency should be established by determination of internal consistency using reliability coefficients while equivalence should be established using alternate form correlation. This paper reviews literature related to the use of multiple choice questions, current design recommendations and processes to establish reliability and validity, and discusses implications for their use in nursing research and education.

The measurement of trust in inter-organisational networks: a conceptual framework and research design

The aim of this paper is to outline a conceptual model and research design for measuring trust in inter-organisational networks which has the potential to be a ‘blueprint’ for a large-scale, multilevel study of trust in networks. Inter-organisational networks are increasingly recognised as a means to achieve economic and social exchange yet, how these networks operate is less widely understood. Trust is widely identified as being essential to the functioning of networks forms of organisation. In order to analyse trust in networks the Social Relations Model (Kenny 1994) of interpersonal perception is applied here. Insights from this model are used to specify relevant components of trust; and extended by incorporating measures of trust at the level of the work group.
