Antioxidative peptides derived from food proteins

The search for natural antioxidants is an ongoing endeavour as an aid to combat the harmful effects of free radicals. Research advances in the past few decades have shown that, by controlled enzymatic hydrolysis, natural antioxidants can be produced from food proteins. In this chapter, the role of certain antioxidative peptides derived from food proteins is discussed in relation to their prospect in the prevention of oxidative stress. The molecular diversity of these food peptides is described together with their pharmacological effects and mechanisms of action in relation to antioxidation. The production of these peptides and the elucidation of their antioxidative peptides are also presented. Owing to their therapeutic potential, antioxidative peptides derived from food proteins can be incorporated as ingredients in functional foods, nutraceuticals and pharmaceuticals, where their biological activities may inhibit product oxidation or assist in the control and prevention of diseases induced by free radicals. However, further insightful research is needed to overcome certain scientific challenges and thereby increase and promote consumer acceptance of these natural antioxidants.

Developing career aspirations of information technology students at Deakin University

It is important for students to develop informed and realistic career aspirations to gain the most value from their university studies towards achieving their initial career goals. However developing students’ career aspirations, goals, and expectations is a complex and discipline-specific process. In Information Technology (IT) no clear career development framework is evident in the literature. Recent research in Australia argues that electronic portfolios are a useful way for students to develop, articulate and document career objectives to enhance their employability. IT students at Deakin engage in formal training and assessment with respect to developing their professional skills and career understandings. Currently electronic portfolios feature as a useful method for evidencing professional competencies for employability. Through a combined quantitative and qualitative analysis of 306 students’ articulated current career aspirations, qualitative analysis of 7 staff opinions of desired student career competencies, and a quantitative analysis of 28 students’ current work personality traits assessments (Work Personality Index), this work presents an analysis of the current state of IT students’ career development. The results indicate that while students reported short-term career aspirations, navigating to their long-term career goals is going to require addressing difficult barriers such as confidence (self-perception) and motivation. This research will influence a larger program-wide endeavour to build student career competencies for employability in IT at Deakin University.

Teacher beliefs in ‘testing’ times: a lesson from Singapore

International benchmarking and national testing of students at all levels of schooling have provoked teachers to critically reflect on their place in this endeavour. Many of the curriculum and pedagogical approaches associated with this type of assessment and accountability conflict with long-held beliefs about the role of teachers and the work of schooling. Singapore is recognised for significant achievement in the international schooling arena and also has a long history of national testing. This study draws specifically on positioning theory to investigate teacher beliefs and positioning in these times. A large qualitative research project located in Singapore sought the ways experienced teachers positioned themselves and their work as they negotiated multiple and sometimes conflicting discourses of teaching. A rigorous process was used to elicit teacher beliefs and resultant teacher positions.

The science of the COAG coordinated care trials

Objectives: To explicate the organisational change agenda of the COAG coordinated care trials within the Australian health system and to illuminate the role of science in this process. Methods and Results: This article briefly outlines the COAG coordinated care trial aims and the effect of the trial as a change initiative in rural South Australia. It is proposed that although the formal trial outcomes are still not clear, the trial had significant impact upon health service delivery in some sites. The trial involved standard research methods with control and intervention groups and with key hypotheses being tested to compare the costs and service utilization profile of intervention and control groups. Formal results indicate that costs were not significantly different between intervention and control groups across all sites, but that the trial, nonetheless, had a powerful impact on the attitude and behaviours of service providers in the rural trial on Eyre Peninsula in particular. Some of the key structural changes now in place are outlined. Conclusions: The COAG trial has had many and varied impacts upon those organisations and individual providers involved with it. It is argued here that since successive initiatives had been implemented before final evaluation results were published, other agendas were served by the trial apart from those of standard scientific research and hypothesis testing. That is, the main impact of the coordinated care trial in Eyre Region at least has been change by stealth, and not through scientific research and demonstration. Implications: The COAG trials have set in train a series of structural and procedural changes in the methods of delivery and management of primary health care systems; changes that are embodied in the Enhanced Primary Care packages (EPC) and other initiatives recently introduced by the Commonwealth Government. These changes have occurred and are occurring across the system without formal evidence as to their efficacy, suggesting that other financial motives are driving these new approaches apart from the goal of improving health outcomes for consumers. Also, if science is to be used in this way to drive policy and procedural change ahead of actual outcome evidence, it is important that we examine the more subtle agendas of such research projects in future if the integrity of the scientific method is to be maintained. The occurrence of such phenomena questions the very foundation of scientific endeavour and weakens the application of scientific principles in the arena of social and political science.

Putting grammar in its place: interactions and identity in a Master of TESOL course

This chapter reports on the development of language awareness and second language identities of a cohort of Chinese TESOL teachers that arose as a result of incidental classroom interactions during a TESOL Masters course in Australia. The experiences of such interactions appeared to help the Chinese teachers make stronger connections between form and meaning, and, while they also reflected deeply on the pedagogies of grammar, they gained a wider view of language teaching and learning that included pragmatic and sociolinguistic awareness. The impact of cultural and educational exchanges and the resulting formations of second language identities is an emerging focus of research (Benson, Barkhuizen, Bodycott and Brown, 2013). In the field of TESOL, such movements and exchanges are creating opportunities to develop a richer discourse, by drawing on diverse traditions of professionalism in different communities and contexts, and calls are increasingly being made for a plural professional knowledge and more inclusive relationships (Canagarajah, 2005; Holliday, 2005; Widdowson, 2004). The People’s Republic of China has been one of the major contributors to student and teacher mobility in recent years; English language is now a priority subject in China, and all students entering university must take the English college test whether they intend to major in English or not, and therefore there has been much interest in upskilling cohorts of Chinese teachers of English to meet this demand. An increasingly typical initiative is to award scholarships to gain professional qualifications in English-speaking countries. A cohort of English teachers from Jiangsu province, China, is the focus of the present study. During their Masters in TESOL course in Queensland, Australia, they experienced interactions with native speakers inside and outside of the classroom. As their course lecturer for several TESOL units, I was interested in the nature of the incidental language awareness arising from course activities with their native-speaking peers. I was also interested in whether they felt that these experiences had implications for their sense of identity in a second language. The following sections therefore discuss the key themes: interaction in higher education contexts, language awareness, and second language identities.

National dance forum 2015

There are ongoing tensions between academics who employ artistic practice as part of their skills set versus artists who enter the academy through a higher degree or taking up a university job opportunity. This panel will address both the pitfalls and opportunities when academic research interacts with creative practice. How one area supports and engages the other is a multifaceted and complex endeavour.

Ontology forecasting in scientific literature:semantic concepts prediction based on innovation-adoption priors

The ontology engineering research community has focused for many years on supporting the creation, development and evolution of ontologies. Ontology forecasting, which aims at predicting semantic changes in an ontology, represents instead a new challenge. In this paper, we want to give a contribution to this novel endeavour by focusing on the task of forecasting semantic concepts in the research domain. Indeed, ontologies representing scientific disciplines contain only research topics that are already popular enough to be selected by human experts or automatic algorithms. They are thus unfit to support tasks which require the ability of describing and exploring the forefront of research, such as trend detection and horizon scanning. We address this issue by introducing the Semantic Innovation Forecast (SIF) model, which predicts new concepts of an ontology at time t + 1, using only data available at time t. Our approach relies on lexical innovation and adoption information extracted from historical data. We evaluated the SIF model on a very large dataset consisting of over one million scientific papers belonging to the Computer Science domain: the outcomes show that the proposed approach offers a competitive boost in mean average precision-at-ten compared to the baselines when forecasting over 5 years.

Una aproximación a la cosmovisión y a la historia de occidente en la obra ensayística de Czeslaw Milosz

This thesis aims to identify the world-view of Czesław Miłosz as it underlies his work; a world-view which comprises historical, philosophical and theological perspectives. With this aim an analysis has been made of the books of essays and the collections of articles of the Polish writer. These form a major part of his literary production: twenty seven of the thirty eight volumes. The work The Land of Urlo (1977) has a special relevance to this endeavour. Two principal hypotheses have been formulated: 1. The world-view of Czesław Miłosz grew out of the assimilation of a series of intellectual influences. The catholic education in his childhood. The encounter in his youth with the gnostic Christian Oskar Miłosz and with Marxism. His contact during the period of the Second Word War and at the beginning of its sequel with the hegelian philosopher Tadeusz Kroński. This world-view had crystalized during his exile. From then he completed his reading of Simone Weil, Emanuel Swedenborg, and William Blake. 2. The world-view of Czesław Miłosz is directly related to his understanding of the History of the West from the beginnings of Christianity to contemporary times. The difficulty in understanding the Weltanschauung of Czesław Miłosz is not of a technical nature (expression in an excessively complex language, dispersion of his work in multifarious archives, collections of letters, etc.). It arises – and only to a lesser degree in his political and philosophical-religeous and biographical essays – out of the author's use of a cryptic language with the intention of hiding a part of his message from view...

Stepwise evolution of the centriole-assembly pathway

The centriole and basal body (CBB) structure nucleates cilia and flagella, and is an essential component of the centrosome, underlying eukaryotic microtubule-based motility, cell division and polarity. In recent years, components of the CBB-assembly machinery have been identified, but little is known about their regulation and evolution. Given the diversity of cellular contexts encountered in eukaryotes, but the remarkable conservation of CBB morphology, we asked whether general mechanistic principles could explain CBB assembly. We analysed the distribution of each component of the human CBB-assembly machinery across eukaryotes as a strategy to generate testable hypotheses. We found an evolutionarily cohesive and ancestral module, which we term UNIMOD and is defined by three components (SAS6, SAS4/CPAP and BLD10/CEP135), that correlates with the occurrence of CBBs. Unexpectedly, other players (SAK/PLK4, SPD2/CEP192 and CP110) emerged in a taxon-specific manner. We report that gene duplication plays an important role in the evolution of CBB components and show that, in the case of BLD10/CEP135, this is a source of tissue specificity in CBB and flagella biogenesis. Moreover, we observe extreme protein divergence amongst CBB components and show experimentally that there is loss of cross-species complementation among SAK/PLK4 family members, suggesting species-specific adaptations in CBB assembly. We propose that the UNIMOD theory explains the conservation of CBB architecture and that taxon- and tissue-specific molecular innovations, gained through emergence, duplication and divergence, play important roles in coordinating CBB biogenesis and function in different cellular contexts.

Databases for quantitative history

This paper will propose that, rather than sitting on silos of data, historians that utilise quantitative methods should endeavour to make their data accessible through databases, and treat this as a new form of bibliographic entry. Of course in many instances historical data does not lend itself easily to the creation of such data sets. With this in mind some of the issues regarding normalising raw historical data will be looked at with reference to current work on nineteenth century Irish trade. These issues encompass (but are not limited to) measurement systems, geographic locations, and potential problems that may arise in attempting to unify disaggregated sources. It will discuss the need for a concerted effort by historians to define what is required from digital resources for them to be considered accurate, and to what extent the normalisation requirements for database systems may conflict with the desire for accuracy. Many of the issues that the historian may encounter engaging with databases will be common to all historians, and there would be merit in having defined standards for referencing items, such as people, places, locations, and measurements.

Adaptive cultural transmission biases in children and nonhuman primates

Comparative and evolutionary developmental analyses seek to discover the similarities and differences between humans and non-human species that illuminate both the evolutionary foundations of our nature that we share with other animals, and the distinctive characteristics that make human development unique. As our closest animal relatives, with whom we last shared common ancestry, non-human primates have beenparticularly important in this endeavour. Such studies that have focused on social learning, traditions, and culture have discovered much about the ‘how’ of social learning, concerned with key underlying processes such as imitation and emulation. One of the core discoveries is that the adaptive adjustment of social learning options to different contexts is not unique to human infants, therefore multiple new strands of research have begun to focus on more subtle questions about when, from whom, and why such learning occurs. Here we review illustrative studies on both human infants and young children and on non-human primates to identify the similarities shared more broadly across the primate order, and the apparent specialisms that distinguish human development. Adaptive biases in social learning discussed include those modulated by task comprehension, experience, conformity to majorities, and the age, skill, proficiency and familiarity of potential alternative cultural models.

Caught between nationalism and internationalism : replicating histories of Antarctica in Hobart

In December 2013, a replica of Mawsons Hut (a historic structure in Antarctica) joined a growing list of polar tourist attractions in the Australian city of Hobart, Tasmania. Initially promoted as the citys latest tourist hotspot, the replica museum quickly took its place in Hobarts newly redeveloped waterfront, reinforcing the citys identity as an Antarctic Gateway. The hut forms part of a heritage cluster, an urban assemblage that weaves together the local and national, the past and present, the familiar and remote. In this article, we examine the replica hut in relation to the complex temporal and spatial relations that give it meaning, and to which it gives meaning. Our focus is the hut as a point of convergence between memory, material culture and the histories-and possible futures-of nationalism and internationalism. We argue that the replica hut, as a key site of Hobarts Antarctic heritage tourism industry, reproduces and prioritises domestic readings of exploration and colonisation over a reading of Antarctic engagement as a transnational endeavour. However, like other gateway city heritage sites, it has the potential for aligning with a larger trend in international heritage conservation and heritage diplomacy, that of prioritising narratives of the past that weave together transnational connections and associations.

Resilience as a double-edged health promotion goal : examples from Lao PDR

Individual and community resilience are undoubtedly important targets for health enhancement and invaluable aspirational outcomes in the health promotion endeavour especially in disaster contexts. However, overreliance on resilience as a proxy for positive well-being has serious personal and political implications in many contexts, as illustrated in research findings on women's quality of life in southern Lao PDR. Case studies derived from focus group interviews with ethnic minority Lao women about their quality of life are used to exemplify how overt signs of resilience may mask, rather than mirror, covert existential reality leaving women without a voice. The political implications of this silencing are profound. Private troubles remain hidden rather than being identified as public issues subject to public policy. This conundrum is not confined to third world countries. Structural limitations to achieving profound fulfilment abound in affluent countries also, yet neo-liberal governments rely heavily on the resilience of populations to minimize public spending. The challenge for health promotion researchers, policy makers and practitioners is to explore the nexus between individual agency and structural change in each specific context to ensure that health promotion initiatives do not inadvertently perpetuate disparities in access to power and resources.

Improving laboratory learning

It has been most encouraging to see science (and innovation)at the forefront of Australian domestic politics in recentmonths. It is also reassuring to see broader bipartisanagreement from the major political parties on the importance ofscience and research to the nation’s future. Governments maychoose to prioritise the areas of scientific endeavour thatwarrant greater support but the acknowledgement by ourpolitical leaders (federal and state) that science and innovationis vital for the nation’s future has not always been forthcoming.The funding mechanisms (e.g. grant schemes) and businessincentives (e.g. taxation) put in place by governments areimportant catalysts of ideally spontaneous processes leading toinnovation and economic advances. However, this pathway isvery complicated.

Towards reflexive ethnicity: museums as sites of intercultural encounter

In a highly globalised world with increasing ethno-nationalistic tensions and conflicts, the importance of intercultural education has never been greater. The challenge remains, however, as to whether educating for mutual respect and social cohesion can be achieved through traditional modes of schooling or whether additional approaches that are not necessarily school-centric are required. Drawing on in-depth qualitative data including video diaries, narrative interviews and focus groups with Australian secondary school students and semi-structured interviews with teachers, this paper discusses such an endeavour in which a museum exhibition on identity and belonging is employed as an interactive space for meaningful encounter among students and as a form of professional learning that enlivened teaching practice. Using the concept of reflexive ethnicity, this paper examines whether cognitive and affective encounters outside the ‘school gate’ create opportunities for critical learning about ethnicity that can complement and enhance school curricula and classroom learning. More importantly, the paper explores how the possibility of building on such activities to create and sustain teaching practice can challenge entrenched static notions of ethnicity.The paper concludes that reflexive encounters with ‘difference’ within an interactive museum space can unsettle prejudice and provide a deeper and more meaningful understanding of ethnic identity that goes beyond rote classroom learning.
