  • The International Journal of Wellbeing: An open access success story

    Weijers, Dan M.; Jarden, Aaron (2017)

    Book item
    University of Waikato

    Academics have long had the advantage of access to university libraries and their expensive subscriptions to scholarly journals. Critics of traditional journal publishing have complained that placing science and scholarship behind a paywall limits its potential. One solution to this problem is the emergence of open access journals. In this chapter, authors Weijers and Jarden offer a case study of a platinum open access journal they founded: the International Journal of Wellbeing. In their discussion of this new journal they offer both philosophical and practical insights that guide their work. They also point to often overlooked issues regarding open scholarship. One of these is the huge numbers of unaffiliated faculty or faculty from non-Western universities, all of whom suffer barriers to access to expensive journals. The authors look to increasing openness of journals to solve this and other problems.

    The first International Conference on Urban Tree Diversity hosted in June 2014 by the Swedish University of Agricultural Science in Alnarp, Sweden highlighted the need for a better understanding of the current state of urban tree diversity. Here we present and discuss a selection of urban tree diversity themes with the intention of developing and sharing knowledge in a research area that is gaining momentum. We begin by discussing the specific role of species diversity in ecosystem service provision and ecosystem stability. This is followed by exploring the urban conditions that affect species richness. Having determined that many ecosystem services depend on urban tree species diversity and that urban environments are capable of supporting high species diversity, we conclude by addressing how to govern for urban tree diversity.

  • Fostering incidental vocabulary uptake from audio-visual materials: The role of text comprehension

    Nguyễn, Chí Đức (2017)

    Doctoral thesis
    Victoria University of Wellington

    This research project explores various factors that may influence the rate of incidental foreign/second language (L2) vocabulary acquisition from audio-visual materials, with a special focus on procedures that enhance learners’ comprehension of these input materials. Informed by relevant theories and research findings in the fields of L2 listening comprehension and incidental vocabulary acquisition, I investigate the effects of having learners (a) view a TED Talks video twice rather than once, (b) sum up the content of the video before watching it a second time, (c) watch TED Talks videos on the same subject in order to increase familiarity with that subject, and (d) exchange summaries of TED Talks videos with peers so as to assist each other’s subsequent processing of those videos. As these interventions are all deemed to facilitate L2 listening comprehension, they are also expected to create favourable conditions for incidental vocabulary uptake to occur. The effects on incidental vocabulary acquisition of the above interventions were gauged in a series of classroom experiments with Vietnamese EFL learners. Although vocabulary uptake was generally far from spectacular, all of the tested procedures were found to result in statistically significant vocabulary gains. The insertion of the output tasks (i.e., the summary activities) was particularly useful. First, they helped to enhance the learners’ text comprehension. Second, they created opportunities for the learners to use newly met words and thus consolidate their knowledge of these lexical items. A thread through the experimental data is the strong association between the learners’ vocabulary uptake and their comprehension of the input content. The findings from this research project are consistent with several established notions, models and theories in the fields, including Ausubel’s Advance Organizer (1978), Hulstijn and Laufer’s Involvement Load Hypothesis (2001), Krashen’s Input Hypothesis (1985), Nation’s Vocabulary Generation (2013), Swain’s Output Hypothesis (2005), and Wittrock’s Model of Generative Teaching of Comprehension (1991). However, there are also findings that go beyond the core tenets of these, and that can further our understanding of how learners process new lexical items in meaning-focused input and output tasks. Regarding pedagogical implications, this research project confirms that fostering L2 listening comprehension creates favourable conditions for incidental vocabulary acquisition to happen, and that the aforementioned classroom procedures are facilitative in this regard, albeit to different degrees.

  • Can we improve participation in university course surveys using mobile tools? : a practical experiment

    Parsons, D.; Rees, M. (2017-05-10T05:37:14Z)

    Conference paper
    Unitec

    Student course surveys provide an important feedback mechanism for universities. However the quality of this feedback depends largely on the level of participation. New technologies have enabled course surveys to evolve from written paper-based tools to web-based and mobile channels, but using these channels does not necessarily lead to better response rates. This paper discusses the results of a survey designed and administered at Massey University, New Zealand, to gain insights into students’ attitudes towards course surveys and factors that might impact on their participation. The survey also explored the potential interest in mobile channels for providing course feedback. The responses to this survey informed a pilot study that tested a mobile course survey tool. The results of our experiment suggest that, whilst a mobile channel may lead to improved participation, more significant results would depend on its integration into a broader set of strategies and tools for student engagement.

  • Considerations on the effect of solutal on the grain size of castings from superheated melts

    Bolzoni, Leandro; Babu, Nadendla Hari (2017)

    Journal article
    University of Waikato

    The amount of solutal present in an alloy affects the grain size of the cast metal as solute is rejected at the solidification front. This is normally quantified using the so called growth restriction factor Q. This work presents some considerations about the effect of solutal on the final cast structure with a focus on the nature of the alloy system, the effect of non-equilibrium solidification conditions and the effect of superheating of the molten metal.

  • Urban Rural Differences in Breast Cancer in New Zealand

    Lawrenson, Ross; Lao, Chunhuan; Elwood, Mark; Brown, Charis; Sarfati, Diana; Campbell, Ian (2016)

    Journal article
    University of Waikato

    Many rural communities have poor access to health services due to a combination of distance from specialist services and a relative shortage of general practitioners. Our aims were to compare the characteristics of urban and rural women with breast cancer in New Zealand, to assess breast cancer-specific and all-cause survival using the Kaplan–Meier method and Cox proportional hazards model, and to assess whether the impact of rurality is different for Māori and New Zealand (NZ) European women. We found that rural women tended to be older and were more likely to be Māori. Overall there were no differences between urban and rural women with regards their survival. Rural Māori tended to be older, more likely to be diagnosed with metastatic disease and less likely to be screen detected than urban Māori. Rural Māori women had inferior breast cancer-specific survival and all-cause survival at 10 years at 72.1% and 55.8% compared to 77.9% and 64.9% for urban Māori. The study shows that rather than being concerned that more needs to be done for rural women in general it is rural Māori women where we need to make extra efforts to ensure early stage at diagnosis and optimum treatment.

    Lincoln University

    Aged population of senior citizens is growing noticeably at different regions in the world. Consequently, there are great numbers of demands for healthcare services. One of the services is assistive walking devices which have important role in mobility, stability, walking, and independency of older adults. Although various type of walking devices are available for older adults, yet fall incidents with severe injuries take place. Therefore, it is critical to analyze fall incidents, find out fall factors, and assess walking devices to minimize fall. This paper mainly focuses on risk factors of fall, considerable role of Information and Communication Technology (ICT) in walking devices, and also analyzes fall incidents with the purpose of understanding how fall incidents take place. This paper assists to have a clear understanding about fall incidents and its associated injuries.

    Journal article
    Lincoln University

    In recent decades, robots have been used noticeably at various industries. Autonomous robots have been embedded in human lives especially in elderly and disabled lives. Elderly population is growing worldwide significantly; therefore there is an increased need of personal care robots to enhance mobility and to promote independence. A great number of aging and disabled hold appeals for using robots in daily routine tasks as well as for various healthcare matters. It is essential to follow a proper framework in ethics of robot design to fulfill individual needs, whilst considering potential harmful effects of robots. This paper primarily focuses on the existing issues in robot ethics including general ethics theories and ethics frameworks for robots. Consequentialism ethics will be recommended to be applied in robot ethics frameworks.

  • A systems approach for determining gene expression from experimental observation of compound presence and absence

    Clark, Sangaalofa; Verwoerd, Wynand S.

    Journal article
    Lincoln University

    Different genes are expressed in different tissues, depending on functional objectives and selection pressures. Based on complete knowledge of the structure of the metabolic network and all the reactions taking place in the cell, elementary modes (EMs) and minimal cut sets (MCSs) can relate compounds observed in a tissue, to the genes being expressed by respectively providing the full set of non-decomposable routes of reactions and compounds that lead to the synthesis of external products, and the full set of possible target genes for blocking the synthesis of external products. So, for a particular tissue, only the EMs containing the reactions that are related to the genes being expressed in those tissues, are active for the production of the corresponding compounds. This concept is used to develop an algorithm for determining a matrix of reactions (which can be related to corresponding genes) taking place in a tissue, using experimental observations of compounds in a tissue. The program is applied to the Arabidopsis flower and identified 20 core reactions occurring in all the viable EMs. They originate from the trans-cinnamate compound and lead to the formation of kaempferol and quercetin compounds and their derivatives, as well as anthocyanin compounds. Analyses of the patterns in the matrix identify reaction sets related to certain functions such as the formation of derivatives of the two anthocyanin compounds present, as well as the reactions leading from the network’s external substrate erythrose-4P to L-Phenyla- lanine, cinnamyl-alc to trans-cinnamate and so on. The program can be used to successfully determine genes taking place in a tissue, and the patterns in the resulting matrix can be analysed to determine gene sets and the state of the tissue.

    Journal article
    Lincoln University

    Two trials were conducted on a Templeton silt loam soil at Lincoln University, New Zealand (43 ° 38' S, 172 ° 28' E.) in 2007/08. The aim was to compare the competitive ability of different pea canopy architectures as influenced by genotype, population, sowing date and their interaction as a means of low input weed control strategy. The first experiment had three sowing dates, two pea genotypes and two herbicide treatments. Experiment 2 treatments were a factorial combination of four pea populations and three sown artificial weed populations. A significant sowing date x pea genotype interaction showed that in the August sowing genotype had no effect on seed yield. However, in September sown plots Pro 7035 yielded 559 g m⁻², which was 40% more than Midichi, and in the October sowing, the difference was 87% more. Herbicide-sprayed peas produced 19% more seed (508 g m⁻²) than the unsprayed plants. When no weeds were sown, the highest pea total dry matter (TDM) of 1,129 g m⁻² occurred at 200 plants m⁻². This was more than twice (513 g m⁻²) the yield of the lowest population (50 plants m⁻²). There was distinct variation in the weed spectrum over time. Coronopus didymus, Stellaria media and Lolium spp were present in relatively large numbers throughout the season. Some weeds only occurred late in the season meaning they could be successfully controlled by early sowing. It could be concluded that it is possible to obtain high pea yields by using the right sowing date and appropriate seed rate as a means of low input weed management strategy.

  • Evolution of specialization of Cassida rubiginosa on Cirsium arvense (Compositae, Cardueae)

    Cripps, M. G.; Jackman, S. D.; Roquet, C.; van Koten, C.; Rostas, Michael; Bourdôt, G. W.; Susanna, A.

    Journal article
    Lincoln University

    The majority of herbivorous insects are specialized feeders restricted to a plant family, genus, or species. The evolution of specialized insect–plant interactions is generally considered to be a result of trade-offs in fitness between possible hosts. Through the course of natural selection, host plants that maximize insect fitness should result in optimal, specialized, insect–plant associations. However, the extent to which insects are tracking plant phylogeny or key plant traits that act as herbivore resistance or acceptance characters is uncertain. Thus, with regard to the evolution of host plant specialization, we tested if insect performance is explained by phylogenetic relatedness of potential host plants, or key plant traits that are not phylogenetically related. We tested the survival (naive first instar to adult) of the oligophagous leaf-feeding beetle, Cassida rubiginosa, on 16 selected representatives of the Cardueae tribe (thistles and knapweeds), including some of the worst weeds in temperate grasslands of the world in terms of the economic impacts caused by lost productivity. Leaf traits (specific leaf area, leaf pubescence, flavonoid concentration, carbon and nitrogen content) were measured as explanatory variables and tested in relation to survival of the beetle, and the phylogenetic signal of the traits were examined. The survival of C. rubiginosa decreased with increasing phylogenetic distance from the known primary host plant, C. arvense, suggesting that specialization is a conserved character, and that insect host range, to a large degree is constrained by evolutionary history. The only trait measured that clearly offered some explanatory value for the survival of C. rubiginosa was specific leaf area. This trait was not phylogenetically dependant, and when combined with phylogenetic distance from C. arvense gave the best model explaining C. rubiginosa survival. We conclude that the specialization of the beetle is explained by a combination of adaptation to an optimal host plant over evolutionary time, and key plant traits such as specific leaf area that can restrict or broaden host utilization within the Cardueae lineage. The phylogenetic pattern of C. rubiginosa fitness will aid in predicting the ability of this biocontrol agent to control multiple Cardueae weeds.

  • A city in a water crisis: the responses of the people of Gaborone

    Kadibadiba, Arabang Tshepiso

    Thesis
    Lincoln University

    Worldwide, countries are challenged by the increasing pressure on potable water resources. In Botswana these pressures are particularly severe. Gaborone, the capital city of Botswana, is faced with a water crisis. There are no nearby permanent water sources to supply the city and successive years of drought led to extreme water shortages in Gaborone in 2015. This study investigates how the government has responded to the developing water shortage over the last decades and how the water use and management practices of the people changed in response to this water crisis. Social practice theory is applied as an analytical theoretical framework with a focus on the elements of practices and the norms of consumption (three Cs of cleanliness, comfort and convenience) reveal how and why consumption takes place. It is shown that the co-evolution of water supply infrastructure and customer demand creates imperatives and expectations that water is always available and ready to be used. It is also concluded that practices of water use are shaped around the concepts of cleanliness, comfort and convenience and that when water was very scarce, practices evolved so that acceptable social standards could still be maintained. The study shows that although people’s practices changed, there were limits to their adaptability in the context of the supply and demand paradigm that dominates water infrastructure across the world. This study illustrates that social practice theory’s conventions of comfort, cleanliness and convenience (the 3Cs) needs to be extended to survival to adequately capture how people respond in a resource constrained situation, which is a contribution this thesis makes to the social practice theory literature. While the importance of technical supply solutions to water situations cannot be overlooked, this study shows that addressing water demand and supply cannot be entirely dependent on them. Understanding people’s social practices and the ways in which they adjust to changes in water provision can be valuable to inform policy aimed at building resilience and adaptive strategies to crisis situations such as water paucity.

  • Efficient analytical moments for the robustness analysis in design optimisation

    Rajan, A.; Ooi, Melanie; Kuang, Y. C.; Demidenko, S. (2017-05-10T05:40:07Z)

    Journal article
    Unitec

    System uncertainties play a vital role in the robustness (or sensitivity) analysis of system designs. In an iterative procedure such as design optimisation, the robustness analysis that is simultaneously accurate and computationally efficient is essential. Accordingly, the current state-of-the-art techniques such as univariate dimension reduction method (DRM) and performance moment integration (PMI) approach have been developed. They are commonly used to express the sensitivity while utilising the statistical moments of a performance function in an advanced design optimisation paradigm known as the reliability-based robust design optimisation (RBRDO). However, the accuracy and computational efficiency scalability for increasing the problem dimension (i.e. the number of input variables) have not been tested. This study examines the scalability of the above-mentioned pioneering techniques. Additionally, it also introduces a novel analytical method that symbolically calculates the sensitivity of the performance function prior to the iterative optimisation procedure. As a result, it shows a better computational cost scalability when tested on performance functions with increased dimensionality. Most importantly, when applied to real-world RBRDO problems such as the vehicle side impact crashworthiness, the proposed technique is three times faster than the mainstream method while yielding a high quality and safe vehicle design

  • I didn’t know what I didn’t know – Postgraduate science students as new library users

    White, BD; Rainier, BA

    Conference paper
    Massey University

    While considerable effort goes into equipping undergraduate students in science, technology, engineering and medicine with knowledge discovery skills and an understanding of the scientific literature, many of them complete their first degrees with a relatively basic level of competence. Undergraduate science education demands an intensive development of subject knowledge and technical skills with less emphasis on the primary literature, and unless an information literacy element is expressly built into science programmes undergraduate students are not routinely required to make use of library resources (Bogucka & Wood, 2009; Wiegant, Scager, & Boonstra, 2011). Postgraduate study, particularly at masters and doctoral level, places quite a different level of demand on students, and even to formulate a research question requires an extensive knowledge of the existing literature. The first part of the thesis journey is the literature review which provides a theoretical and methodological grounding of the whole project, but students often arrive at postgraduate study poorly equipped to perform this task (Hoffmann, Antwi-Nsiah, Feng, & Stanley, 2008; Miller, 2014). Those skills that they have acquired tend to be based around Google and Google Scholar (Wu & Chen, 2014) which provide a good result for relatively little effort, but which lack the functionality to fully support a literature review at this level (Johnson & Simonsen, 2015). Increasing internationalisation of postgraduate education is another factor impacting on this situation, although it would be wrong to assume that English-speaking students or those from “developed countries” possess the appropriate skills for an advanced degree literature review.

  • Sleep-hygiene education improves sleep indices in elite female athletes.

    O'Donnell, Shannon; Driller, Matthew W. (2017)

    Journal article
    University of Waikato

    The importance of sleep in providing psychophysiological recovery in elite athletes is often overlooked. In other populations (eg shift workers and adolescent students), sleep hygiene education may serve to acutely improve sleep indices. However, this is yet to be examined in an elite athlete setting. Therefore, the aim of the current study was to evaluate the effect of a sleep hygiene education session on sleep indices in elite athletes. The study involved 26 elite female netball athletes performing one week of baseline sleep monitoring (PRE), followed by a sleep hygiene education session and a further week of sleep monitoring (POST) in a single group, pre- post design. The sleep hygiene education session focused on providing information on the importance of sleep for athletes and practical tips to improve sleep quality and quantity. Sleep monitoring was performed using wrist actigraphy to assess total sleep time (TST), sleep efficiency (SE%), total time in bed (TTB), sleep latency (SL), wake episodes per night (WE), sleep onset variance (SOV), wake variance (WV) wake episode duration (WED), sleep onset time (SOT), and wake time (WT). There was a significant improvement in TST (mean ± SD; 22.3 ± 39.9 minutes, p=0.01) PRE to POST sleep hygiene education session, the difference associated with a small effect (ES: 0.39). A significant improvement PRE to POST was found for WV (p=0.03), and for WED (p=0.03). There were no significant differences for SE%, SL, TTB, WE, SOV, SOT, WT. The current study reports that a sleep hygiene education session is effective in improving sleep quantity in elite female athletes in an acute setting.

  • Determination of maximal oxygen uptake using the Bruce or a novel athlete-led protocol in a mixed population

    Hamlin, Michael J.; Draper, N.; Blackwell, G.; Shearman, J. P.; Kimber, Nicholas E.

    Journal article
    Lincoln University

    Treadmill tests for maximal oxygen uptake (V O2max) have traditionally used set speed and incline increments regardless of participants training or exercise background. The aim of this study was to determine the validity of a novel athlete-led protocol for determining maximal aerobic fitness in adults. Twenty-nine participants (21 male, 8 female, age 29.8 ± 9.5 y, BMI 24.4 ± 3.1, mean ± SD) from a variety of exercise backgrounds were asked to complete two maximal treadmill running tests (using the standard Bruce or a novel athlete-led protocol [ALP]) to volitional failure in a counter-balanced randomised cross-over trial one week apart. We found no substantial difference in maximal oxygen uptake (47.0 ± 9.1 and 46.8 ± 10.7 ml.kg-1.min-1, mean ± SD for the ALP and Bruce protocols respectively), evidenced by the Spearman correlation coefficient of 0.93 (90% confidence limits, 0.88-0.96). However, compared to the Bruce protocol, participants completing the ALP protocol attained a substantially higher maximal heart rate (ALP = 182.8 ±10.5, Bruce = 179.7 ± 8.7 beats.min-1). Additionally, using the Bruce protocol took a longer period of time (23.2 ± 17.0s) compared to the ALP protocol. It seems that using either treadmill protocol will give you similar maximal oxygen uptake results. We suggest the ALP protocol which is simpler, quicker and probably better at achieving maximal heart rates is a useful alternative to the traditional Bruce protocol.

  • ICTs in climate change communication in the Pacific Islands

    Harris, U.; Papoutsaki, Evangelia; Kailahi, S. (2017-05-10T05:39:41Z)

    Journal article
    Unitec

    Community participation is essential to effectively address communities’ needs in relation to climate change. Conventional media forms that are easily accessible in the Pacfic Islands region, including digital media, require strategic integration of both message creation and dissemination with stakeholder inclusion. This article argues that use of information and communication technologies (ICTs) not only enables information dissemination, but also invites local participation in communicative processes. Greater citizen engagement in content creation improves community understanding of the issues around climate change by including local perspectives, cultural knowledge, and concerns specific to the area. Recording, sharing, and discussing these changes in community settings will inform new thinking, with the potential to change perceptions and attitudes toward this urgent problem.

  • Relational accountability in indigenizing visual research for participatory communication

    Thomas, V.; Eggins, J.; Papoutsaki, Evangelia (2017-05-10T05:39:30Z)

    Journal article
    Unitec

    This article argues that an indigenous approach to communication research allows us to re-think academic approaches of engaging in and evaluating participatory communication research. It takes as its case study the Komuniti Tok Piksa project undertaken in the Highlands of Papua New Guinea. The project explores ways in which visual methods when paired with a community action approach embedded within an indigenous framework can be used to facilitate social change through meaningful participation. It involves communities to narrate their experiences in regard to HIV and AIDS and assists them in designing and recording their own messages. Local researchers are trained in using visual tools to facilitate this engagement with the communities.
