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
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
STEM educational engagement through coopetition, sport and wearable technology
Full text linkStudent engagement in Science, Technology, Engineering and Mathematics (STEM) activities are often perceived as solitary activities, resulting in a limited range of students that are intrinsically interested in it [1]. Historically STEM activities are often about “things rather than people” [2]. For those whom STEM is not perceived as intrinsically interesting, its lack of relevance to everyday life and social engagement means potential STEM students’ interests are focussed elsewhere.
A previously reported education program [3] utilised a range of sports technologies and sport-based activities to engage students in sport and play activities that were more likely to be of interest and have a significant social context through working as a team and competition. These were then linked to classroom activities involving numeracy and engineering based. The vehicle for this were principally inertial sensors, which have emerged in recent decades as a viable alternative for the quantification of human movement at the elite level [4] as well as emerging as popular consumer electronics [5] through wearable technologies (an important hook for children).
Recent studies of the program (STEMfit) [6] measured its efficacy for educational engagement and improving education outcomes [3]. These investigations garnered international interest for the potential to undertake cross cultural activities and exchange (even in a pandemic). Typically, in this program, physical activities are combined with classroom-based analysis using time series data developed from the STEMfit program and collected using a single body worn inertial sensor (Fig. 1).
Here we introduce the ISEA STEMfit International cup, an ISEA Education co-sponsored program that was supported by global expertise in inertial sensors from the wider ISEA community. Furthermore, it supports interest in translational outcomes to foster the education of children as a pathway into STEM careers, in particular in Sports Engineering. Figure 1 shows a sample activity, jumping together with associated time series data collection and visual representation of the vertical axis. The analysis can be varied and scaled, depending on student capabilities e.g. early primary school students may count how many jumps they did in 10 seconds.
In the developed competition and through partner schools of the co-authors, student teams from around the globe competed in a series of physical Olympic style athletic events and by using a range of sports technologies, collected data for a STEM analysis project. Student teams were judged by an international panel comprising of a senior sports engineer, an inertial sensor manufacturer, and an elite sports athlete/administrator. Students made a video presentation of their STEM analysis (in their own language and English) to share with other teams.

Residential IEQ improvement using UVGI lights and carbon fibre filters: Mould and relative humidity assessments
Full text linkMany New Zealand residential homes suffer from poor indoor environmental quality (IEQ). Cold, damp, and mould-ridden homes can cause serious respiratory health problems. Poor IEQ can arise due to poor insulation and ventilation, and is compounded when residents cannot afford heating. Features of the residential building code mean many New Zealand houses built under old standards lack wall insulation, have single glazing on windows and are poorly ventilated. A major indicator of poor IEQ is mould growth, which can cause, or exacerbate, respiratory illness. This project assesses the results of modifying an existing dehumidifier to include ultraviolet germicidal (UVGI) lights and two different types of filters (CityPleat and 30/30). The original device altered IEQ by removing moisture. The modified device was designed to further improve IEQ by performing filtration and purification of the air, with the addition of the CityPleat, 30/30 filters with the UVGI lights. This project investigates the impact on various IEQ elements, such as room temperature, particulate matters (PM2.5), and relative humidity using an air imaging sensor (compatible with current WHO guidelines), with a focus on mould growth. We found the different filtration scenarios presented reduced the relative humidity effectively in the room compared to the baseline dehumidifier action only. The results show that adding the 30/30 filter with the UVGI lights increased the room temperature by 2.2oC, reduced the relative humidity by 10%, and reduced the PM2.5 values from 2.5 µg/m³ to 0.4 µg/m³ in the room after three hours of operation. Mould growth, as measured in agar plate coverage, was also reduced by the addition of the filtration and UVGI lights
The Australasian association for engineering education
Full text linkSub-Themes are:
1. Beyond the qualification – future-proofing engineering education for a diverse workforce. (National Strategy)
a. Strategies for increasing diversity of student intake often exist within institutions. However what happens to students once they graduate? Have students been prepared for the diverse workforce that will emerge as a result of an increasingly diverse student intake?
2. Beyond tolerance – educational practices that embrace diversity. (Teaching Strategy)
a. Diverse perspectives add value to the classroom, as well as to the workplace. How can we move beyond merely tolerating different viewpoints to creating educational spaces that encourage, develop and allow the ideas of an increasingly diverse student group to flourish?
3. Beyond the classroom – tailoring engineering and STEM education to meet the needs of all stakeholders. (External Industry requirement)
a. Educational institutions must consider an increasingly diverse group of stakeholders, including students, staff, industry, and the wider community. How can educational activities expand our horizons beyond classroom and industry experience
Residential air quality improvement system
Full text linkMany New Zealand homes suffer from cold, damp and mould-ridden homes during the winter which can cause respiratory health problems. This can be due to poor insulation and ventilation and is made worse when residents cannot afford heating. The main aim of this paper is to modify an existing dehumidifier which can remove moisture, heat the home and reduce the mould and bacteria. To achieve that we combined the properties of a dehumidifier with ultraviolet germicidal lights (UV), which have been proven to effectively destroy the DNA of mould and bacteria. The result shows that the device reduced the mould growth and did increase the room temperature. This due to the fact that the dehumidifier captured 2 litters of water over 24 hours of testing. This shows that the device did improve the indoor air quality (IAQ) in the room
Chair a session/Integration of theory and practice in the learning and teaching process
Full text linkThe theme for AAEE-2017 is “Integrated Engineering”, which covers a range of sub-themes, such as:
Integration of theory and practice in the learning and teaching process Interdisciplinary and cross-disciplinary engineering programs and learning environments Integration of teaching and research in the engineering training process
The role and impact of engineering students and educators in the wider community Systems perspectives on engineering education.
Integration is also about connections, e.g. between students and teachers, between students in learning together, and between educational institutions and industry and wider society in the engineering education process
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
