Neoliberalism has become the dominant ideology of our day. As with all ideologies, it influences without drawing attention to itself. Critical pedagogy, with its focus on the oppressed and marginalised, offers a perspective on the media and education that seeks to expose neoliberalism's hegemonic power. Traditional media has become complicit with neoliberalism, but with new media's role in the recent events of the Arab Spring and the Iranian uprisings, there is hope that it can expose and challenge unjust powers. New media, or more specifically for this article, YouTube, is a contested frontier where the power is sought: critically, the power of the imagination. To engage on YouTube is to be on that frontier, and new skills are required. This article concludes that critical media literacy is essential to successfully engage that space and provide the opportunity for users to imagine a different world. Source

Education has long been regarded as the foundation stone of national growth and international competitiveness. In the last three decades national educational reforms to improve access to higher education qualifications, individual higher education institutions' aggressive national and international marketing initiatives and improved information and communication technology (ICT) systems and infrastructure have resulted in greatly increased participation in tertiary education. As a consequence of this wider participation, tertiary educators are now engaging with increased numbers of culturally and economically diverse learners in distributed ICT environments that they, the educators and learners, are often unfamiliar with. There is an expectation that these educators will be able to design learning modules to meet students' multi-cultural needs, in a range of contexts, with no additional resources. In essence, it is expected that learners will participate in individually customised learning events at a cost similar to traditional delivery. This requires a fundamental shift in educators and learners conceptions on the provision of education. The purpose of this paper is to explore how the development and deployment of reflective frameworks, based on recognised international standards, can fully engage learners in mass-customised environments. First this article outlines the key building blocks required for reflective mass-customisation to occur. Second, it illustrates how this concept is being tentatively explored at a New Zealand institution. Finally, it recommends the areas of action for further research on the impact and effect of masscustomisation on learners, educators and institutions to be undertaken. © J. Clayton. Source

While referent tracking is considered highly problematic, researchers have generally concluded that adult second language learners face few problems with referent introductions. However, previous studies have typically blurred the distinction between recognitional and non-recognitional introductions and have largely focused on the noun phrase as the primary unit of analysis, overlooking the complex multi-stage and interactional practices used to refer to entities with low accessibility. The present study addresses these issues in the analysis of references by native and non-native speakers in a film retelling task, and additionally explores the interlocutors' interpretations of references through stimulated recall interviews, thereby identifying which introductions were miscommunicated. The findings suggest that, even for relatively competent second language speakers, introductions pose a substantially greater communicative and acquisitional challenge than has been previously reported, with evidence presented of miscommunications triggered by under-explicitness. The findings highlight theoretical issues in interlanguage pragmatics and the methodological value of analysing interpretations of learner speech; pedagogically, the findings suggest a need for addressing the complex move structure and interactional practices for achieving recognition. © 2016 Elsevier B.V.

Rapid Communications in Mass Spectrometry | Year: 2011

We describe a new, simple, robust and efficient method based on direct-tissue matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry that enables consistent semi-quantitation of peptide hormones in isolated pancreatic islets from normal and diabetic rodents. Prominent signals were measured that corresponded to all the main peptide hormones present in islet-endocrine cells: (α-cells) glucagon, glicentin-related polypeptide/GRPP; (β-cells) insulin I, insulin II, C-peptide I, C-peptide II, amylin; (δ-cells) somatostatin-14; and (PP-cells), and pancreatic polypeptide. The signal ratios coincided with known relative hormone abundances. The method demonstrated that severe insulin deficiency is accompanied by elevated levels of all non-β-cell-hormones in diabetic rat islets, consistent with alleviation of paracrine suppression of hormone production by non-β-cells. It was also effective in characterizing hormonal phenotype in hemizygous human-amylin transgenic mice that express human and mouse amylin in approx. equimolar quantities. Finally, the method demonstrated utility in basic peptide-hormone discovery by identifying a prominent new Gcg-gene-derived peptide (theoretical monoisotopic molecular weight 3263.5 Da), closely related to but distinct from GRPP, in diabetic islets. This peptide, whose sequence is HAPQDTEENARSFPASQTEPLEDPNQINE in Rattus norvegicus, could be a peptide hormone whose roles in physiology and metabolic disease warrant further investigation. This method provides a powerful new approach that could provide important new insights into the physiology and regulation of peptide hormones in islets and other endocrine tissues. It has potentially wide-ranging applications that encompass endocrinology, pharmacology, phenotypic analysis in genetic models of metabolic disease, and hormone discovery, and could also effectively limit the numbers of animals required for such studies.

This paper investigates the ability of impedance based fault locating systems in series compensated lines. Behaviour of Series capacitors and their built-in protection system has been studied to analyse the dynamics of the system during short circuit faults. This paper also aims at investigating attempt to provide a framework to facilitate a reliable decision making in the real time situation by amending conventional fault locating algorithms. The algorithm is simulated using MATLAB Simiilink for a 220kV transmission line. © 2015 IEEE. Source
