Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
DigiExplanation driven assignments for personalising learning in construction education
Full text linkPersonalising learning is critical for universities to achieving excellence in education. It entails maintaining an education system that is responsive to the learning needs, aptitudes and interests of individual students. Rather than imposing a ‘one-size fits all’ model, personalising learning is anticipated to ensure that every learner achieves his/her highest potential. Pedagogical literature suggests that learning-oriented assessments that are engaging, authentic and relevant are an effective mode for personalisation. DigiExplanations is a novel approach that requires students to create short digital media to communicate their ideas to ordinary audiences. It offers an opportunity for research-based authentic learning by harnessing digital media that exist outside of their institution and their digital competencies to create personally relevant and interesting resources. The aim of the research was to investigate the effectiveness of digiExplanations driven assessments for improving personalised learning in construction education. A case study strategy was adopted in the research. A first-year subject from the construction management degree was chosen as the case, which had a class of 159 students. A new assignment scheme was introduced for which students were required to develop digiExplanations in groups of five. The assessment criteria comprised: rationale for the study; depth and breadth of the discussions for the topic; appropriateness of media used in the discussions; creativity in the use of media (storyboarding); design of digiExplanation; quality of conclusion; and proper acknowledgement of materials used. After the submission deadline, an online survey was conducted with the students to assess how the new assessment approach facilitated personalised learning. Several findings emerged from the study. The digiExplanations based assignment provided similar learning experiences for students with different characteristics concerning their first language, domestic/international student status, work situation and digital competencies. Moreover, the study found that some considerations are more significant than others in designing assessments that can drive personalised learning, which are: personally relevant/interesting, engagement, harnessing internet resources and progressive feedback. The survey findings further suggest that while the new pedagogical approach achieved its intended aim, few students perceived it a cumbersome method as it required more efforts than traditional assignments
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Evidence-based post-occupancy behaviour framework for energy consumption in BASIX-compliant dwellings in Sydney, Australia
Full text linkGovernment energy policy framework and regulation play a critical role in driving reductions in energy consumption and carbon emissions in the building sector; for example, the BASIX policy framework regulates energy, water and thermal performance requirements for residential buildings in NSW. More than 140,000 dwellings have been built in NSW under BASIX, since it was launched in 2004. However, recent studies have found discrepancies between the modelled and actual energy performance in BASIX-complaint dwellings. Hence, the NSW government initiated a large research project in collaboration with the CRC for Low Carbon Living (CRCLCL) to investigate and identify the causes of this energy performance discrepancy in BASIX-compliant dwellings and this doctoral research is a subset of this large research project.
The aim of this doctoral research is to understand post-occupancy behaviour in BASIX-compliant dwellings that may lead to the discrepancy between modelled and actual energy performance and inform the BASIX policy framework, design decisions and government education programme. In alignment with this aim, there are four objectives defined in this research:
1. Investigate the key post-occupancy energy-related behaviour that may cause the energy performance discrepancy in BASIX-compliant dwellings.
2. Identify the influential attributes that may affect post-occupancy energy-related behaviour in higher energy consumption.
3. Identify complex associations among post-occupancy energy-related behaviour and multi-dimensional influential attributes, that may contribute to the higher energy consumption in BASIX-compliant dwellings.
4. Draw on key findings to establish an evidence-based post-occupancy behaviour framework for residential energy consumption to inform BASIX policy framework, government education programmes, and building design/construction.
A literature-based, conceptual analysis framework was initially developed in this research, and guided the data collection and in-depth analysis. The research was conducted in both the cool season and the warm season in 2017. The primary data collection was through three activities: face-to-face interviews with households in 30 BASIX-compliant dwellings; site and dwelling inspections; and behaviour observations. These data were analysed using systematic thematic analysis method. As this study is part of CRCLCL BASIX project, secondary data derived via a demographic survey, real-time electricity monitoring, indoor thermal environment monitoring, and building diagnostic methods of the same dwelling sample were used to triangulate with primary data to establish credibility and trustworthiness of findings.
The findings of the in-depth analysis verified and refined the theory based initial conceptual analysis framework and informed the development of the Post-occupancy Energy-related Behaviour (PEB) framework, which supports to comprehensively understand the higher energy consumption in BASIX compliant dwellings with energy performance discrepancy. It established that energy-related behaviours in dwellings are a combination of direct energy-use behaviour, adaptive behaviour, and investment behaviour; however, in dwellings with higher energy consumption, direct energy-use behaviour was identified to be predominant, and occupants used energy excessively and inefficiently for air conditioning, lighting and hot water consumption. Those inefficient practices were identified to frequently occur for reasons beyond traditionally anticipated human needs of achieving thermal or visual comfort and were due to reasons, such as season independent habits, forgetfulness, lack of awareness, work efficiency concerns, and health and wellbeing of occupants. The in-depth investigation identified that those behaviours are shaped by five attributes: personal, social, building and environmental, economic, and governance, in simple to complex hierarchical associations.
Personal attributes, such as preferences, perceptions, awareness, personal characteristics, and attitudes, social attributes, such as family lifestyle and spatial utilisation pattern, and community practices were identified as directly influencing energy-related behaviour in those dwellings with higher energy consumption. For example, most dwellings had home offices, which supports the growing trend of occupants working remotely and spending more time inside their dwelling during the day. In addition, the research identified that the occupants’ thermal comfort related perceptions, preferences, awareness and attitudes in energy consumption in those dwellings with higher energy consumption were influenced by the construction systems and building envelope quality of dwellings, construction market and cost concerns and lack of governance support.
Many complex patterns of associations were derived from the in-depth analysis of this research that further support understanding of the higher energy consumption in those BASIX-compliant dwellings. Examples of such identified associations are:
– associations between occupants’ perceptions on thermal comfort, income concerns, building conditions, and geographic location of dwellings influence intensive use of air conditioners for cooling and less passive strategies for thermal comfort;
– associations between the availability of air conditioning systems in dwellings, occupants’ thermal comfort preferences, and the level of awareness on the use of air conditioning influence direct energy-use behaviour in intensive cooling; and
– associations between characteristics and conditions of dwellings’ that facilitate thermal comfort and occupants’ level of awareness on strategies for thermal comfort, influence occupants’ thermal perceptions that in turn influence Investment behaviour on heating/cooling appliances and direct energy-use behaviour in intensive heating/cooling practices.
The key insights and implications derived from the findings of this study provided recommendations for BASIX policy, government education programmes and building design/construction.
This research is significant as it is a unique investigation into post-occupancy energy-related behaviour in BASIX-compliant dwellings with energy performance discrepancy, and key findings fill the current knowledge gap. Unlike previous studies of post-occupancy energy-related behaviours that have conducted quantitative studies, this study adopted an in-depth qualitative approach to develop comprehensive understanding into BASIX-compliant dwellings in Sydney, with energy performance discrepancies. The findings of this research have already informed 2018-2019 updates in the BASIX Policy Framework and could further inform government educational programmes to promote sustainable energy use behaviour. This would ultimately improve low carbon dwellings to facilitate the transition towards net-zero carbon outcomes in 2050
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
