description: Setting an effective learning experience for students is a very complex process and yet, this has become even more challenging as the numbers of students in lectures are increasing. Apart from the usual complexities such as additional administration processes and errors associated with large units, there are other critical issues that need to be addressed. In particular, students may not have the opportunity of reasonable interaction with the lecturer and their classmates. Certainly larger units have the potential to provide an opportunity of having a wider range of lateral thinking and innovative ideas. However, these opportunities are often overlooked as there is no practical tool to support them. In this paper we report on our ongoing work using a Wiki for two different units, one an undergraduate unit and another at a postgraduate level. We found that while there are considerable differences between our perception and students’ perceptions on using a Wiki, it can be a powerful tool for providing a space for students to present and record their efforts. Through using Wiki students can effectively disseminate their work and interact beyond their tutorial classes.
title: A Stylometric Analysis of Seneca’s Disputed Plays. Authorship Verification of Octavia and Hercules Oetaeus

Year: 2024

description: Seneca’s authorship of Octavia and Hercules Oetaeus is disputed.
This study employs established computational stylometry methods based on
character n-gram frequencies to investigate this case. Based on a Principal
Component Analysis (PCA) of stylistic similarities within the Senecan corpus,
Octavia and Phoenissae emerge as outliers, while Hercules Oetaeus only stands
out when the text is split in half. Subsequently, applying Bootstrap Consensus
Trees (BCT) to a corpus of distractor texts, both disputed plays align with the
Senecan cluster/branch. The General Impostors method confidently reports
Seneca as the author of the disputed plays under various scenarios. However,
upon closer examination of text segments, indications of mixed authorship arise.
Based on computational stylometry, it appears that the disputed plays were in
large part, but not wholly, written by Seneca.

description: Reviewing numerous textbooks, we found that in both differential and integral calculus textbooks the authors commonly assume that: (i) students can generalize associations between representations in two dimensions to associations between representations of the same mathematical concept in three dimensions on their own; and (ii) explicit discussions of these representations are not necessary. For example, in the presentation of partial derivatives, textbook presentations assume that students will understand the slope in a specified direction in without it ever being explicitly presented. Our preliminary interviews indicated that such assumptions may be erroneous, so we created and tested materials that explicitly use representations commonly omitted in textbook presentations of the differential and integral calculus of functions of two and three variables. This paper discusses the classroom activities that were created to include these missing representations, as well as the results when they were implemented in classroom instruction.

description: Increasingly universities are adopting a collaborative approach to ensure research outcomes have industry-relevant impact. This collaboration has known challenges given the complexity of the process which requires successful negotiation across the needs of various stakeholders, disciplinary knowledges and cultural contexts. A co-creation approach in collaborative research can assist in navigating these challenges by empowering all stakeholders including industry, the academy and the community. This paper presents a case study of an industry engaged research project that employed this approach. Partnering with a northern European international airline and universities from Australia and Singapore, the project investigated opportunities for innovation around the ageing population’s user experience with in-flight packaging. Applying case study method, data collected included in-flight observations, expert interviews, co-creation workshops and prototyping. Challenges as well as opportunities are identified around how the co-creation approach supported the industry relevant outcomes of the project. The findings suggest that co-creation supports better outcomes for collaboration across the complexity of industry engaged cross-cultural research projects.

description: A set of advanced networking laboratory rooms have been designed and built as part of Swinburne University of Technology's new Advanced Technology Centre (ATC) to facilitate the learning of both fundamental and advanced networking concepts and to ensure that students attain conceptual, design, professional and social skills. The main aim is to give students a more realistic network experience, which is achieved through increased access to equipment, and increased flexibility in how equipment can be utilised. This facility allows students to dynamically connect various computers within the room to different physical networking devices through the use of virtual networks. Multiple devices can be interconnected, both within and between enclosures. Overall power consumption is reduced through the use of managed power cycling and end-host virtualization. This paper outlines the physical, logical and teaching rationale behind the design and construction of the laboratory environment. We discuss the use of virtualisation to establish multiple hosts per kit of equipment and its implications on sustainability.
To Brunswick and beyond: a geography of creative and social participation for marginalised youth
Creators: name: Podkalicka, Aneta
Publisher: name: Swinburne
Year: 2024

description: This article uses a case study of a Melbourne-based youth media project called Youthworx to explore the processes at stake in cultural engagement for marginalised young people. Drawing on ethnographic research conducted between 2008 and 2010, I identify some ways in which the city is implicated in promoting or preventing access to socially valued spaces of creativity and intended social mobility. The ethnographic material presented here has both empirical and theoretical value. It reveals the important relationships between the experience of place, creativity, and social life, demonstrating potentialities and limits of creativity-focused development interventions for marginalised youth. The articulation of these relationships and processes taking place within a particular city setting has theoretical implications. It opens up an opportunity to consider 'suburbs' as enacted by specific forms of access, contingencies, and opportunities for a particular demographic, rather than treating 'suburbs' as abstract, analytical constructs. Finally, my empirically grounded discussion draws attention to cultural and social consequences that inhabiting certain social worlds and acts of travelling 'to and beyond' them have for young people.
Is collecting anonymous but code-identified intervention assessment data worth the effort? Reflections on a recent study in electronics
Creators: name: Mazzolini, Alexander

Publisher: name: Swinburne
Year: 2024

description: Often the effectiveness of an educational intervention for a large lecture group is assessed by testing the cohort before and after the intervention and measuring any improvement in the aggregated data from pre- to post-testing. A limitation of this method is that not all students may attend the pre-test, post-test or the lectures where the intervention is administered, diluting the significance of the results. An alternative approach is for students to use a unique but anonymous research code that allows researchers to 'tag' each individual student and hence identify those students who participate in all intervention activities and tests ('complete responders'). This paper argues that tagged data can increase the statistical significance of an intervention hypothesis when compared to untagged data even when the statistical sample is small. In a recent study that tested the efficacy of interactive lecture demonstrations (ILDs) in improving students' conceptual understanding for an advanced topic in electronics (AC resonance), the 'complete responders' formed a relatively small subgroup (N=21) of the full group (N=86) that participated in all or only some of the activities or tests ('all responders'). The learning gains for the 'complete responders' were more significant than those of 'all responders'. The reasons for the increased significance are discussed in this paper.

description: Learning and teaching innovation is becoming more necessary in engineering, particularly with the new Engineers Australia Stage 1 Competencies and the 'voucher' system starting in 2012. There is also increasing pressure on academics to undertake research and publish. In Australia, a small number of groups have formed to meet these challenges and help engineering academics develop their education research practices. However while these groups have developed in and are focused on their local context, the factors that influenced their creation and support or hinder their growth have implications for similar groups in future. This paper aims to compare and contrast three such groups to identify essential elements of engineering education research groups in Australasia. Three case studies are presented from the perspective of the coordinators of the groups, along with a thematic analysis conducted across the three cases.

description: New Venture Failure (NVF) is a well researched field, emphasising the importance of learning and recovering from it. However, discrete information on how one can learn from NVF is rather scanty. This study explores how 27 experienced Australian entrepreneurs and intrapreneurs perceive NVF, and what they have learned from it. We conclude with a conceptual model to help novice and nascent entrepreneurs and intrapreneurs succeed in their first venture, based on the suggestion given by the participants.

description: Movement of Walleyes Sander vitreus among reaches in a large, fragmented river was assessed by employing a combination of tagging, telemetry, and genetic analyses. Our objective was to determine whether the existing dams in the Ottawa River, Canada, were impeding Walleye movement among river reaches. Movement was predicted to be greater among contiguous, unimpounded reaches in comparison with impounded reaches. In total, 1,586 Walleyes were tagged in five river reaches, and 35 Walleyes were tracked by radiotelemetry in three river reaches. Genetic analyses (linkage disequilibrium, genetic divergence and diversity, effective population size, genetic structuring, bottlenecks, and migration rates) were conducted on 221 Walleyes from seven river reaches by genotyping at six microsatellite loci. Based on both tag returns (return rate = 12.1%) and telemetry data, there was limited movement among river reaches whether impounded or unimpounded, and movement was predominately upstream. Genetic analyses identified population structuring, with three genetic groupings occurring within the river. There was also evidence of genetic isolation in an upper reach of the river, indicating potential residual effects of a bottleneck or genetic drift. Our results suggest that existing dams may not act as significant barriers to Walleye movement in the Ottawa River, but limited movements appear to maintain genetic diversity and minimize genetic drift. Consequently, maintaining the genetic attributes of Walleye stocks in segmented rivers may require some level of fish passage.Received July 9, 2012; accepted January 16, 2015
Disruption revisited: Netflix, Apple TV, Google TV, Facebook TV
Creators: name: Barr, Trevor
Publisher: name: Swinburne

description: Historically, television and media content have generally been tied to specific distribution platforms or outlets. However, multiple new players and new forces are at work now driving significant changes. Four business models have been constructed in this paper, about current initiatives for Internet based television in the USA, which have the potential to challenge the established television industry. First, Netflix with its 'aggregation model' currently runs the largest 'watch instantly' streaming content service in the USA. Second, Apple TV’s ‘walled garden’ model offers an iTunes compatible streaming media device intended to revolutionise how Americans view television. Third, Google TV, with its 'convergence is free' model, now claims that it offers a major in-built innovation that television has lacked for so long — the web. And fourth, Facebook’s 'social media is ubiquitous' model has only recently enabled large movie studios in the USA to use the Facebook site as their first mode of movie release. The paper analyses how these new television services relate to the work of two established theorists on innovation, Joseph A Schumpeter, regarded as a pioneering thinker about 'creative destruction', and Clayton Christensen, who popularised the term 'disruptive technology'. So how transformational might the long term effects of current Internet television innovation become? On a scale from minor disruption to major destruction, what might emerge regarding long term changes to television as a service for its viewers, and to the industry?

description: A better author could probably write a detective story about the word pudding. The cultural and linguistic complex associated with this word spans in its full extent a thousand years and six continents. This paper concerns itself only with its semantic evolution in English, and its spread to several of the geographically closest languages: German, French, and Italian, each of which has a different relationship with both the word and the dish. The intention is not to explain everything, it is too early for that, but rather to sketch the overall picture and thus to highlight those areas which require further investigation.

description: One of the two aims of the Australian Learning and Teaching Council (ALTC) funded Define Your Discipline (DYD) project is to develop an efficient, inclusive, simple and systematic stakeholder consultation process that can be used by discipline stakeholders to define their discipline. During 2010 the DYD stakeholder consultation process was developed and then trialled nationally to develop a draft set of Graduate Outcomes for the environmental engineering discipline. The first part of the paper describes the DYD stakeholder consultation process which uses both divergent and convergent strategies to ensure that the individual voices of the participants are captured, as well as group perspectives. Data was gathered on the tasks undertaken by graduates during their first two or three years of practice. Once the 2010 stakeholder consultation workshops had been completed the data were synthesised to define a draft set of Graduate Outcomes for the discipline. Two different types of workshop are being used during 2011 to refine the draft set of Graduate Outcomes. Throughout this process each outcome remains linked to all of the identified tasks from which it was derived, and the people who submitted those tasks. Thus, the project team can review the importance of the contributions from the various groups of participants (such as academics, graduates and practitioners) as well as some of the characteristics of those groups such as location, and gender. The second part of the paper discusses the feedback received from members of the stakeholder groups who participated in the DYD stakeholder consultation process: 50 of the 110 workshop participants; the project team; and the client---the Environmental Engineering College Board. Overall, the feedback from all parties was very positive. The feedback from the 2010 workshops was used to fine-tune the DYD consultation process for the 2011 workshops.
Developing engineering design expertise though reflection

description: The three key elements of engineering design expertise---framing, systemic thinking and the conscious application of first principles---have been shown to be difficult to acquire by both students and practicing professionals. Because of this, it is of value to investigate how framing, systemic thinking and the application of first principles can be better developed in engineering students which will in turn develop better graduate design engineers. This paper reports on a project to do this in two mechanical engineering design subjects. Students were introduced to one or all of the three key elements of engineering design expertise, encouraged to apply them in a design project and practice questions throughout the semester of study. Finally, students were examined on their framing ability and their ability to apply first principles. It was found that only around 15% to 20% had a developed framing ability. Further, the ability to apply first principles appeared to be bimodal some students could apply them almost completely, some could not apply them at all and only a few could apply them partially. This suggests that skills related to engineering design expertise can only be learned by some students or that the current education system (including earlier schooling) has not developed sufficient related skills in the majority of students. This requires further research.

description: Because of the rise of anthropogenic sources of NP human exposure to NP has dramatically increased in the recent years, in the general population as well as in workers (e.g., welders). This raises the question of the potential adverse effects of NP on human health, particularly at the respiratory level, since it represents the main route of exposure for air pollutants. Since inhalation exposure is the most relevant but yet under evaluated route of exposure for the evaluation of NP toxicity our study was aimed to design, build, and characterize a safe inhalation system dedicated to evaluate the respiratory effects of NP in mice. We chose to focus on the generation of iron (Fe) and manganese (Mn) oxide NP distributions centered on 20–25 nm diameters at concentrations of 107–108 NP/cm3 as it is representative of the occupational exposure of welders. Fe and Mn NP aerosols were generated with the spark discharge generator technique with air as a carrier gas conditio sine qua non for the mice. Indeed, the spark generator has been widely studied and used but in noble gases (N2, Ar, . . .) suggests the absence of oxidation. Aerosol particles are characterized in terms of size distribution, concentration, morphology, and chemical composition. Exposure of mice for 1 to 4 days (3 h a day) to these occupationally relevant aerosol concentrations induces inflammatory effects (increased lung total protein content). Moreover, clusters of particles were observed throughout the lungs.Copyright © 2015 American Association for Aerosol Research
Community participation in the development of digital radio: the Australian experience

description: The participation of the community broadcasting sector in the development of digital radio provides a potentially valuable opportunity for non-market, end user-driven experimentation in the development of these new services in Australia. However this development path is constrained by various factors, some of which are specific to the community broadcasting sector and others that are generic to the broader media and communications policy, industrial and technological context. This paper filters recent developments in digital radio policy and implementation through the perspectives of community radio stakeholders, obtained through interviews, to describe and analyse these constraints. The early stage of digital community radio presented here is intended as a baseline for tracking the development of the sector as digital radio broadcasting develops. We also draw upon insights from scholarly debates about citizens media and participatory culture to identify and discuss two sets of opportunities for social benefit that are enabled by the inclusion of community radio in digital radio service development. The first arises from community broadcasting's involvement in the propagation of the multi-literacies that drive new digital economies, not only through formal and informal multi- and trans-media training, but also in the 'co-creative' forms of collaborative and participatory media production that are fostered in the sector. The second arises from the fact that community radio is uniquely placed - indeed charged with the responsibility - to facilitate social participation in the design and operation of media institutions themselves, not just their service outputs.

description: In adult skin epidermis and the epithelium lining the esophagus cells are constantly shed from the tissue surface and replaced by cell division. Tracking genetically labelled cells in transgenic mice has given insight into cell behavior, but conflicting models appear consistent with the results. Here, we use an additional transgenic assay to follow cell division in mouse esophagus and the epidermis at multiple body sites. We find that proliferating cells divide at a similar rate, and place bounds on the distribution cell cycle times. By including these results in a common analytic approach, we show that data from eight lineage tracing experiments is consistent with tissue maintenance by a single population of proliferating cells. The outcome of a given cell division is unpredictable but, on average, the likelihood of producing proliferating and differentiating cells is equal, ensuring cellular homeostasis. These findings are key to understanding squamous epithelial homeostasis and carcinogenesis.

description: A comparison between three different types of particle sizing instruments (fast mobility particle sizer, FMPS; electrical low pressure impactor, ELPI; and scanning mobility particle sizer, SMPS) and one condensation particle counter (CPC) was made to compare instrument response in terms of size distributions and number concentration. Spherical oil droplets in 39 different sizes, with geometric mean diameter (GMD) ranging from 50 nm to 820 nm, were used as test particles. Furthermore, a characterization of the FMPS unipolar charger behavior was made to analyze the measured size distributions and number concentrations. The results show that all three sizing-instruments agree well for particle sizes below 200 nm, both in terms of size and number concentration, but the FMPS deviates clearly when particle sizes exceed 200 nm. Above this, the FMPS underestimates the particle size throughout the remainder of the size range, with an apparent upper limit for GMD of 300 nm. It also estimates a higher particle number concentration as compared to the other instruments. Analysis of the 22 FMPS electrometer currents and calculation of average number of charges per particle show a diameter dependence of response of for the FMPS unipolar charger. The resulting calculated electrical mobility showed a minimum in mobility for spherical particles at 577 nm, which indicates an interfering range of particles above the measurement range, but below the cut-off of the inlet pre-separator (1 μm). The study concludes that particle distributions with a true GMD above 200 nm cannot be measured reliably with the FMPS.Copyright 2015 American Association for Aerosol Research
Constrained Bayesian optimization for automatic chemical design using variational autoencoders.

Publisher: name: Apollo - University of Cambridge Repository
Year: 2019

description: Automatic Chemical Design is a framework for generating novel molecules with optimized properties. The original scheme, featuring Bayesian optimization over the latent space of a variational autoencoder, suffers from the pathology that it tends to produce invalid molecular structures. First, we demonstrate empirically that this pathology arises when the Bayesian optimization scheme queries latent space points far away from the data on which the variational autoencoder has been trained. Secondly, by reformulating the search procedure as a constrained Bayesian optimization problem, we show that the effects of this pathology can be mitigated, yielding marked improvements in the validity of the generated molecules. We posit that constrained Bayesian optimization is a good approach for solving this kind of training set mismatch in many generative tasks involving Bayesian optimization over the latent space of a variational autoencoder.
The internet in Australia 2011: initial findings from the World Internet Project
Creators: name: Ewing, Scott
Publisher: name: Swinburne

description: This paper outlines initial findings from the most recent survey of the Australian component of the World Internet Project (WIP). WIP is a collaborative survey-based project looking at the social, political and economic impact of the Internet and other new technologies. The paper argues that while Australian internet use is very high and for some segments of the population approaching universality this has the potential to exacerbate the disadvantage of those not online. Despite a drop in support between 2009 and 2011 the National Broadband Network is still supported by a clear majority of Australians. While our research indicates that many Australians have integrated the internet into their daily lives our data overall indicates a plateau in many activities and the NBN has the potential to facilitate a new cycle of innovation. Finally it finds that the internet has become the most important source of news and information for users while pointing to the continuing problem of developing funding models given consumer resistance to paying for online content.

description: Исследования проводили с целью изучения влияния видов, возрастающих доз и кратности внесения твердых и жидких азотных удобрений в ранневесеннюю подкормку на урожайность и качество зерна озимой пшеницы для совершенствования технологии возделывания культуры. Эксперименты выполняли в 2016–2019 гг. в Центральном Предкавказье. Территория проведения опытов находится в зоне неустойчивого увлажнения, почва – чернозем выщелоченный, мощный, среднегумусный тяжелосуглинистый. В трехфакторном опыте изучали эффективность подкормки возрастающими дозами (35, 70, 105, 140 кг/га д.в.) различных азотных удобрений (аммиачная селитра (Naa) и карбамидно-аммиачная смесь (КАС)) и кратности их внесения (однократное, дробное). Контроль – без подкормки. На фоне повышенного температурного режима во все годы исследований (на 0,2…2,2 оС больше среднемноголетнего) гидротермический коэффициент в 2016/17 сельскохозяйственном году был равен 1,24, в 2017/18 г. – 0,74; в 2018/19 г. – 0,63. Все изучаемые дозы азотных удобрений обеспечили достоверную прибавку урожайности озимой пшеницы, по сравнению с контролем (0,82…2,80 т/ га). Дробное внесение КАС и аммиачной селитры оказалось эффективным только при использовании дозы 140 кг/га д.в. В этих вариантах отмечен наибольший сбор зерна – 6,34 и 6,22 т/га соответственно. Азотные удобрения, вне зависимости от вида и кратности внесения, значительно увеличили содержание белка и клейковины в зерне, по сравнению с контролем, на 0,8…3,9 % и 1,3…10,2 % соответственно. С экономической точки зрения из изученных вариантов наиболее предпочтительно дробное внесение карбамидно-аммиачной смеси в дозе N70+70: прибыль – 47866 руб./ га, уровень рентабельности – 139 %.

description: In this study, the thermogravimetric analysis (TGA) technique has been applied to determine the extent of in situ polymerization achievable in solid wood on treating with bio-polyester oligomers. Low-molecular-weight oligomers of poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(butylene succinate) (PBS), and poly(butylene adipate) (PBA) were impregnated and then thermally polymerized within solid wood to enhance the physical properties of wood. TGA revealed a similar degree of oligomer polymerization was achieved either with pure oligomers or within the wood structure. The influence of relatively acidic treatments, such as low-molecular-weight PGA oligomers, was observed to lead to degradation of the hemicellulose wood component. Polymerization of PLA and PGA oligomer treatments which penetrate the wood cell wall gave relatively lower wood thermal stability. Treatment and polymerization of lumen filling PBS and PBA oligomers contributed to increased wood thermal stability.

description: The discipline of archaeology is uniquely positioned to allow for inclusion of culturally appropriate curricula to be incorporated into student learning objectives as mentioned in the 94 Calls to Action by the Truth and Reconciliation Commission of Canada (2015). In this paper the authors discuss the creation, implementation, and qualitative feedback of a community-directed and curriculum-based education program developed by graduate students that uses archaeology to mediate student learning and meet curriculum goals in both classroom and land-based environments. This experiential learning initiative involves graduate and undergraduate students, and students from a local Indigenous community and the surrounding area. Feedback from educators and student participants, both Indigenous and non-Indigenous found that the experience fostered a deeper understanding of longstanding histories of the land and increased cultural appreciation. The paper outlines program development, curriculum connections, community engagement, as well as educator and student feedback. This programming can be used as a framework, and the creation of local and place-based education initiatives is encouraged within other disciplines to facilitate pedagogy for reconciliation.

description: A new synthetic approach for α-ketoamides was achieved by copper-catalyzed coupling reactions between N,N-dialkylformamides and phenylacetic acids. A variety of substrates were well tolerated to give yields of 46–87% (17 examples). A 13C-labeling experiment revealed that the carbonyl group of the products came from the phenylacetic acid.

description: Исследования проводили с целью подбора наиболее продуктивных сортов сои для увеличения производства зерна при оптимизации влагообеспеченности посевов путем орошения. Работа выполнена в условиях степной зоны Центрального Предкавказья в 2005–2011 гг. Почва опытного участка – карбонатный мощный малогумусный тяжелосуглинистый чернозем на лессовидном суглинке. Материалом для исследования служили 12 сортов разных групп спелости южного экотипа. Предшественник – озимая пшеница. Норма высева семян скороспелых сортов – 600 тыс. шт./га, раннеспелых – 550 тыс. шт./га, среднеспелых – 500 тыс. шт./га. Ширина междурядий 70 см. Поливы проводили дождевальной машиной ДДА-100МА расчетной поливной нормой, которая в среднем составляла 350…580 м3/га. В группе скороспелых сортов период всходы–цветение был наиболее коротким (37 дн.), у раннеспелых и среднеспелых сортов он увеличивался на 4…9 дн. Период от цветения до налива бобов был наиболее продолжительным и сильно варьировал по группам спелости – сорта раннеспелой и среднеспелой групп проходили его на 8…13 дн. дольше, чем скороспелые. Период вегетации в среднем за годы исследований у скороспелых сортов составил 102 дн., у раннеспелых и среднеспелых – на 15…26 дн. дольше. В среднем за 2005–2011 гг. самая высокая урожайность в опыте сформирована при выращивании среднеспелого сорта Селекта 302 – 2,51 т/га, что больше стандарта (Вилана) на 0,07 т/га, прибыль в этом варианте составила 25536,3 руб./га, при себестоимости 12826,2 руб./т и рентабельности 79,3 %.

description: Background: Process evaluation is important for improving theories of behavior change and behavioral intervention methods. The present study reports on the process outcomes of a pilot test of the theoretical model (the Process Model for Lifestyle Behavior Change; PMLBC) underpinning an evidence-informed, theory-driven, group-based intervention designed to promote healthy eating and physical activity for people with high cardiovascular risk. Methods: 108 people at high risk of diabetes or heart disease were randomized to a group-based weight management intervention targeting diet and physical activity plus usual care, or to usual care. The intervention comprised nine group based sessions designed to promote motivation, social support, self-regulation and understanding of the behavior change process. Weight loss, diet, physical activity and theoretically defined mediators of change were measured pre-intervention, and after four and 12 months. Results: The intervention resulted in significant improvements in fiber intake (M between-group difference = 5.7 g/day, p < .001) but not fat consumption (-2.3 g/day, p = 0.13), that were predictive of weight loss at both four months (M between-group difference = -1.98 kg, p < .01; R2 = 0.2, p < 0.005), and 12 months (M difference = -1.85 kg, p = 0.1; R2 = 0.1, p < 0.01). The intervention was successful in improving the majority of specified mediators of behavior change, and the predicted mechanisms of change specified in the PMBLC were largely supported. Improvements in self-efficacy and understanding of the behavior change process were associated with engagement in coping planning and self-monitoring activities, and successful dietary change at four and 12 months. While participants reported improvements in motivational and social support variables, there was no effect of these, or of the intervention overall, on physical activity. Conclusions: The data broadly support the theoretical model for supporting some dietary changes, but not for physical activity. Systematic intervention design allowed us to identify where improvements to the intervention may be implemented to promote change in all proposed mediators. More work is needed to explore effective mechanisms within interventions to promote physical activity behavior.

description: Spatial ability is an important tool in chemistry and this ability can be improved. Various technologies have been used to improve spatial ability. However, it is not clear if viewing technologies should take the place of the model kit; the traditional method of learning about molecular structures. Our research aims to address this gap. In our study, we aimed to take advantage of student affinity to technology to drive spatial ability improvements (in the context of chemistry) by having students experience molecules in virtual space using modern viewing technologies (WBVE, AR, and VR). Students were first engaged with the technologies then were assessed to see if their ability to solve problems relating to 3D-molecular structure improved. The mean spatial ability of students improved over the course of the semester (permutation test, p < 0.05) and students using model kits scored higher than those using the technologies (t-test, p < 0.05). The collection and assessment of anonymous, aggregated, student responses for this study was conducted with the approval of the University of Calgary ethics board (REB13-0724).
