Cholinesterase Research Outreach Project (CROP): measuring cholinesterase activity and pesticide use in an agricultural community

BACKGROUND: Australian farmers and their workers are exposed to a wide variety of pesticides. Organophosphate (OP) insecticides are a widely used class of pesticide used for animal husbandry practices (Naphthalophos for sheep dipping, jetting and drench), crop production for pest control (Dimethoate) and in public health (Maldison for head lice). Acute poisonings with this class of insecticide are reported among agricultural workers and children around the globe, due to the inhibition of acetylcholinesterase (AChE). Less is known about chronic exposures. Regular monitoring of erythrocyte AChE will enable farmers to identify potential exposure to organophosphate insecticides and take action to reduce exposures and improve their health and safety practices. This study aims to assess and improve the integration of AChE monitoring into routine point of care health clinics, and provide farming and non-farming people with a link between their AChE activity and their household chemical and agrichemical use. METHODS/DESIGN: The research will target individuals who work on mixed farming enterprises and routinely using OPs (n = 50) and non-farmers (n = 30). Baseline data are collected regarding demographic, health conditions and behaviours, Kessler 10 (K10) scores, chemical use and personal protection. Baseline anthropometric measures include height, weight, hip and waist circumference, body fat analysis and, biochemical analysis of fasted total serum cholesterol, triglycerides, low-density cholesterol (LDL), high-density cholesterol (HDL) and blood glucose. Analysis of erythrocyte cholinesterase (EAChE) activity is also conducted using a finger prick test. Testing of EAChE is then repeated in all participants every 3 weeks for a maximum of three times over a period 10 weeks. Participants are provided with full feedback and counselling about their EAChE activity after each reading and a detailed summary provided to all participants at the completion of the study. Data will be analysed using repeated measures within a general linear model. DISCUSSION: This work will provide an evidence base and recommendations for the integration of EAChE monitoring into Australian rural health clinics, leading to research which will further quantify pesticide exposure both on the farm and in the home, highlighting the importance of sustaining and providing a safe work and home environment for farming communities.

Improving student-industry engagement through project oriented curriculum

Industry expects a creative and innovative academic practice that provides students with valuable practical knowledge focused on graduate ready skills for future careers. The learning environment in engineering is inadequate for students to become a skillful graduate. The practical role of engineering is gained through working on real world problems in an industry collaborative environment through projects. Industry academia collaboration seems to be actively increasing in the development of engineering education in various parts of the globe. The close relationship between industry and academia is a vital component of the engineering pedagogy to improve student engagement in industry through projects. By engaging students with industry, students will acquire global perspective about the core attributes expected in future engineering jobs. In today’s large-scale industrial market, companies tend to prefer graduates with design skills attained through the project approach. Thus, universities should open their doors and accept the challenges of interacting with students with industrial experiences and expectations. This paper is focused on improving student industry engagement through project/design oriented curriculum. Through quantitative and qualitative research, the paper shows the industry perspectives and students views on university and industry collaboration. The research results show that students and industry can possibly maintain their engagement by providing regular feedback, reviewing goals and objectives, improving communication, keeping focused, and sharing a similar vision.

Lessons learnt from dancing the data : performed research of beginning teachers' experiences

This paper discusses the power of performed research. Such power lies in assisting to research the whole human – thought, action, and emotion. The paper discusses the potential for research through the arts in the development of creativity and imagination, to facilitate social change, and to explore performance as a research process as well as an end result that presents findings. The experiences of Bagley and Cancienne (2001); (2002) guided the creation of the work, and assist to frame this paper. The dance work discussed in this paper is a recent addition to the performed research work ‘The First Time’. The dance work was crafted to bring together the comparable experiences of first year teacher participants, and similarities among the findings of research into their identity. The creation of ‘The First Time’ was employed as a tool to understand and analyse the data. The dance work was employed to highlight findings regarding beginning teachers’ transition to teaching. This paper explores the process of creating and presenting arts-based research to expand the avenues through which the results of research are made available to a relevant audience; of how this method might broaden and complement traditional ways of thinking about and doing educational research.

Detonating the research plan: exploding the supervisory process

Bomb making is dangerous work. And not just because what you’re creating can blow up in your face. Even as you type in your search terms – how to make a bomb – you wonder who is watching, what algorithm might throw you up into the light of surveillance and trigger the knock at the door. (McKnight, 2014, p. 1)AbstractSo begins Lucinda’s PhD. In this dialogic paper of interwoven stories we employ a critical auto-ethnographic approach to explode moments of our lives and work together as we worked through the “research plan” at the heart of the supervision timeline. Lucinda’s thesis highlights the way curriculum emerges from the struggles of ideological becoming (Bakhtin 1981) as she and a group of teachers, sought to produce and perform both individual gendered identities (Butler 1997, 2007) and plans for the identities of student subjects, while negotiating subject positions made available to girls and women in broader social contexts. The link between the personal and political is created by a methodology combining narrative inquiry and discourse analysis as a heteroglossic (Bakhtin, 1981) text. In this paper we detonate the research plan developed in the first months of the PhD timeline as Jo responds to Lucinda’s narratives with her own, and we share jointly written narratives that try to capture some key moments of the process. We rework our own stories of the supervised and the supervisor through the competing discourses of our work and lives.

Building, shaping, forming, researching with metaphor

Ben Whitburn and Lucinda McKnight are two recent Deakin PhD graduates who thought with metaphor in their doctoral research projects, and found this process both exhilarating and frustrating. Ben teaches in inclusive education, and Lucinda is a professional writer who teaches in education; they bring to this workshop their different perspectives on how metaphor can be useful for consciously initiating creative and cohesive research strategies, and also how it can be insidious in restricting our worldviews.They will introduce participants to theory underpinning metaphor and provide opportunities to explore this theory in the context of HDR students' own projects, whether in Humanities, Communication, Creative Arts or Education.• How might metaphor assist with inspiring a research design?• How might metaphor invite researcher reflexivity?• What kinds of metaphors have other researchers employed?• What can we learn from the ways in which metaphor inevitably fails?These questions and others will be considered; participants should come prepared to write, talk, draw and think!

Re-presenting and representing with seven features: guiding an arts-based educational journey

This paper outlines a journey of arts-based inquiry into teacher education and identity transformation in the transition to teaching, guided by Barone and Eisner’s Seven Features of Arts-Based Educational Inquiry. Employing a theatre-based research approach the researcher investigated teachers’ epiphanic or revelatory first moments of identity transformation, culminating in the creation of the play script and performance: ‘The First Time’. The article discusses what Barone and Eisner’s works offered this arts-based researcher on their journey. Outcomes of the research include the value of working backwards from this frame for further data elucidation and analysis and presenting research to relevant ‘expert’ audiences.

A perspective on supporting STEM academics with blended learning at an Australian university

Design-based educational research can aid in providing a lens into understanding the complexities around imaginative methods, while also creating an avenue to share personal insights to support the solving of teaching and learning problems to direct future efforts. In this study, the ‘I’ narrative was extensively utilised in the form of an autoethnography perspective. This was achieved by incorporating three self-report methods within a design experiment, in order to explore the messiness associated with showcasing the creation and modification of a faculty-wide blended learning framework for STEM teachers. Data generation procedures from three sources provided the evidential basis for investigating this process: (1) self-reflection, (2) key literature findings, and (3) critical discussions from a community of inquiry. The findings identified three particular features of the process of change that were challenging, for which STEM academics required support: educators’ professional context; finding models to support change in practice; and identifying the change agent. The paper argues for the program of a personal and complex methodology to inform practice, providing insights into the change process, because process is just as important as product.

Swimming lessons : learning, new materialisms, posthumanism, and post qualitative research emerge through a pool poem

This article shifts from the formal learning spaces of school anduniversity to an Australian public swimming pool to playfullyengage some of the dilemmas that recent theory poses forcurriculum studies. The article enacts multiple diffractions(Barad, 2007) as theory becomes swimming and swimmingbecomes theory, and ideas and movements are themselvesdiffracted or changed by the writing of a poem. What does thepool teach us? What is learnt at the pool? How does learningemerge at the pool? Physics, chemistry, biology, and artistrycombine, as multiple human and non-human bodies intra-act(Barad, 2007), calling each other into being in this exploration ofhow distributed agencies and fractal causalities (Bennett, 2010)change how learning might be thought, represented, andswum. The poem incorporated here serves as provocation andinspiration for other scholars struggling with these educationaldilemmas and interested in arts-based research.

GEB (Children@School): a scale for measuring the impact of school design on children's general environmental behaviours

While there are many environmental education programs for children, few studies have used an appropriately developed scale for evaluating children’s environmental behaviours, informed by the school- design.The research presented in this paper used an adapted GEB (General Ecological Behaviour) scale to develop a scale for measuring children’s environmental behaviours in Australian schools; GEB (Children@School). This scale has been informed by the evidenced impact on children’s behaviour of their environment.A review of the literature reveals that assessing environmentalbehaviours across different domains is a complex issue. In the absence of a reliable ecological behaviours scale, the GEB scale was developed by Kaiser in 1998 as a scientifically grounded measure. The GEB is assumed to be the most generalizable and allencompassing environmental behaviour measure compared to the other environmental behavioural measures.In order to develop the GEB (Children@School), 624 children, aged 10-12 years old completed a survey. Factor analysis indicated that this scale has two dimensions: Children’s Pro-active Ecobehaviours, and Children’s Environmental Behaviours towards Resource and Energy Conservation. The estimate reliability omega value was calculated for each of the identified factors and the results indicated that the scale has a reasonable internal consistency. This suggests that GEB (Children@School) is an appropriate scale to meaningfully measure children’s environmental behaviours when associated with school-design.

Affordances of using multiple videoed events to construct a rich understanding of adult-child book readings

This paper explores the affordances of using video-based research to capture a multiplicity of events, along with multimodal representations when producing data related to adult–child book readings. In doing this we answer two questions: (1) why more than one event is needed when seeking a comprehensive collection of information for the purpose of analysis; and (2) why one mode of data production alone (e.g. audio recordings or note taking) is insufficient to record practice or interviews when richness is of priority. This research used three videoed events to produce data. These included videoing: (1) caregiver–child interactions during four shared book reading sessions, (2) interviews with caregivers immediately following each of the reading sessions and (3) video-stimulated discussions with caregivers within two months of the final shared book reading. In this paper, I contribute to discussions that highlight the affordances of using video-based research as a means of capturing the multimodal elements of an experience, which can contribute to the analysis and interpretation of data. I expand on this, however, to suggest that when coupled with a multiplicity of events, video-based research can be a means of pursuing richness via a method that has been criticized for its narrow subjectivity.

Comparison of bovine RNA polymerase III promoters for short hairpin RNA expression

RNA interference (RNAi) mediated by DNA-based expression of short hairpin RNA (shRNA) is a powerful method of sequence-specific gene knockdown. A number of vectors for expression of shRNA have been developed that feature promoters from RNA polymerase III (pol III)-transcribed genes of mouse or human origin. To advance the use of RNAi as a tool for functional genomic research and for future development of specific therapeutics in the bovine species, we have developed shRNA expression vectors that feature novel bovine RNA pol III promoters. We characterized two bovine U6 small nuclear RNA (snRNA) promoters (bU6-2 and bU6-3) and a bovine 7SK snRNA promoter (b7SK). We compared the efficiency of each of these promoters to express shRNA molecules. Promoter activity was measured in the context of RNAi by targeting and suppressing the reporter gene encoding enhanced green fluorescent protein. Results show that the b7SK promoter induced the greatest level of suppression in a range of cell lines. The comparison of these bovine promoters in shRNA expression is an important component for the future development of bovine-specific RNAi-based research.

Mega-events and the "Showcase" effect: investigating the moderating influence of exposure to the 2004 Olympic games telecast and interest in the Olympic movement- an Australian perspective

Survey-based research explored the moderating effects of "exposure" to the Australian free-to-air telecast of Athens 2004 and "interest" in Olympic Games in developing behavioral intentions to visit Greece in the future. Differences were found between groups with low and high levels of exposure to the telecast, and also between groups with high levels of interest in the Olympic Games, but these were only marginal. When the combinatorial influences of these two variables were considered simultaneously, their effects were generally synergistic. The article calls for further research on this area of mega-events, as the results, while of significance, provide food to continue the broader debate on the role of mega-events in developing tourism to their host destinations after their staging.

Utilizing hyperlink transitivity to improve web page clustering

The rapid increase of web complexity and size makes web searched results far from satisfaction in many cases due to a huge amount of information returned by search engines. How to find intrinsic relationships among the web pages at a higher level to implement efficient web searched information management and retrieval is becoming a challenge problem. In this paper, we propose an approach to measure web page similarity. This approach takes hyperlink transitivity and page importance into consideration. From this new similarity measurement, an effective hierarchical web page clustering algorithm is proposed. The primary evaluations show the effectiveness of the new similarity measurement and the improvement of web page clustering. The proposed page similarity, as well as the matrix-based hyperlink analysis methods, could be applied to other web-based research areas..

Waste production simulation for building deconstruction projects

The recently erected concept of building deconstruction has significantly promoted building components and materials reuse and recycling where building is carefully dismantled into reusable parts. Current research and practices of building deconstruction mainly focus on issues of process before and during the deconstruction such as hazardous material detection, deconstruction design and deconstruction technology. The issues after the deconstruction project are rarely considered. Waste reuse and recycling are enabled through deconstruction yet not practically achieved, and especially the demands of waste building components and materials are hard to appear and match the actual waste production in a building deconstruction project. To deal with this awkward situation, the waste production needs to be conducted in a demand-oriented way. It needs to be thoughtfully planned and scheduled prior to the physical deconstruction as an essential portion of deconstruction project planning and scheduling. Furthermore, the relationship between waste production and structural characteristics of the building creates a serious consideration affecting a deconstruction plan. As a result, a waste production simulation will facilitate waste reuse and recycling in a deconstruction project. It serves as a crucial section of deconstruction planning and design. This research aims to describe the concept of waste production simulation and investigate various management and technical aspects of waste production simulation for building deconstruction projects.

Public satisfaction with police : using procedural justice to improve police legitimacy

Policing research and theory emphasises the importance of supportive relationships between police and the communities they serve in increasing police effectiveness in reducing crime and disorder. A key reason people support police is that they view police as legitimate. The existing research literature, primarily from the United States, indicates that the most important factor in public assessments of police legitimacy is procedural justice. The present study is the first in an Australian jurisdiction to examine the effect of procedural justice and police legitimacy on public satisfaction with police. Using responses to a large postal survey (n = 2611), findings show that people who believe police use procedural justice when they exercise their authority are more likely to view police as legitimate, and in turn are more satisfied with police services. This study differs to US-based research in the greater importance of people's evaluations of instrumental factors in judgments of police legitimacy. The findings are important as they confirm that people's assessments of fair and effective policing in Australia will be enhanced by policing strategies that emphasise the use of procedural justice in encounters with the public.
