Dealing with affective needs in e-learning: Contrasting two cases in two cultures.

This chapter presents and contrasts descriptions of two cases of online affective support provided to support students engaged in higher level learning tasks. The cases are set in different cultures, centre upon different intended learning outcomes, and follow different tutorial styles. One (Eastern) tutor acted as a “shepherd leader” in response to needs arising in the Confucian Heritage Culture as the teacher promoted critical thinking, according to the Western model. The other (Western) tutor provided Rogerian facilitation of reflective learning journals, kept by students seeking to develop personal and professional capabilities. In both styles, affective support features strongly. The cultural and pedagogical comparisons between the cases have proved useful to the writers. These distinctions together with the similarities between the two online styles emerge in the comparisons. Keywords: affective needs, asynchronous discussion, Confucian Heritage Culture, constructivism, critical thinking, facilitation, reflection, reflective learning journals, Rogerian, shepherd leadership, social-constructivist, student-centred, support.

Mammalian cell cultures as a model system for the determination of cytotoxicity induced by cholesterol oxidation products

Oxysterols are products of cholesterol oxidation, which may be produced endogenously or may be absorbed from the diet where they are commonly found in foods of animal origin. Oxysterols are known to be cyctotoxic to cells in culture and mode of toxicity has been identified as apoptosis in certain cell lines. The cytotoxicity of the oxysterols 25-hydroxycholesterol (25-OH) and 7β-hydroxycholesterol (7β-OH) was examined in two human cell lines, HepG2, a hepatoma cell line, and U937, a monocytic cell line. Both 25-OH and 7β-OH were cytotoxic to the HepG2 cell line but apoptotic cells were not detected and it was concluded that cells underwent necrosis. 25-OH was not cytotoxic to the U937 cell line but it was found to have a cytostatic effect. 7β-OH was shown to induce apoptosis in the U937 line. The mechanism of oxysterol-induced apoptosis has not yet been fully elucidated, however the generation of an oxidative stress and the depletion of glutathione have been associated with the initial stages of the apoptotic process. The concentration of cellular antioxidant enzyme, superoxide dismutase (SOD) was increased in association with 7β-OH induced apoptosis in the U937 cell line. There was no change in the glutathione concentration or the SOD activity of HepG2 cells, which underwent necrosis in the presence of 7β-OH. Many apoptotic pathways center on the activation of caspase-3, which is the key executioner protease of apoptosis. Caspase-3 activity was also shown to increase in association with 7β-OH-induced apoptosis in U937 cells but there was no significant increase in caspase-3 activity in HepG2 cells. DNA fragmentation is regarded as the biochemical hallmark of apoptosis, therefore the comet assay as a measure of DNA fragmentation was assessed as a measure of apoptosis. The level of DNA fragmentation induced by 7β-OH, as measured using the comet assay, was similar for both cell lines. Therefore, it was concluded that the comet assay could not be used to distinguish between 7β-OH-induced apoptosis in U937 cells and 7β-OH-induced necrosis in HepG2 cells. The cytotoxicity and apoptotic potency of oxysterols 25-OH, 7β-OH, cholesterol- 5a,6a-epoxide (a-epoxide), cholesterol-5β,6β-epoxide (β-epoxide), 19-hydroxy-cholesterol (19-OH), and 7-ketocholesterol (7-keto) was compared in the U937 cell line. 7 β-OH, β-epoxide and 7-keto were found to induce apoptosis in U937 cells. 7β-OH-induced apoptosis was associated with a decrease in the cellular glutathione concentration and an increase in SOD activity, 7-keto and β-epoxide did not affect the glutathione concentration or the SOD activity of the cells.a-Epoxide, 19-OH and 25-OH were not cytotoxic to the U937 cell line.

Computational Journalism: from Answering Question to Questioning Answers and Raising Good Questions

Our media is saturated with claims of ``facts'' made from data. Database research has in the past focused on how to answer queries, but has not devoted much attention to discerning more subtle qualities of the resulting claims, e.g., is a claim ``cherry-picking''? This paper proposes a Query Response Surface (QRS) based framework that models claims based on structured data as parameterized queries. A key insight is that we can learn a lot about a claim by perturbing its parameters and seeing how its conclusion changes. This framework lets us formulate and tackle practical fact-checking tasks --- reverse-engineering vague claims, and countering questionable claims --- as computational problems. Within the QRS based framework, we take one step further, and propose a problem along with efficient algorithms for finding high-quality claims of a given form from data, i.e. raising good questions, in the first place. This is achieved to using a limited number of high-valued claims to represent high-valued regions of the QRS. Besides the general purpose high-quality claim finding problem, lead-finding can be tailored towards specific claim quality measures, also defined within the QRS framework. An example of uniqueness-based lead-finding is presented for ``one-of-the-few'' claims, landing in interpretable high-quality claims, and an adjustable mechanism for ranking objects, e.g. NBA players, based on what claims can be made for them. Finally, we study the use of visualization as a powerful way of conveying results of a large number of claims. An efficient two stage sampling algorithm is proposed for generating input of 2d scatter plot with heatmap, evalutaing a limited amount of data, while preserving the two essential visual features, namely outliers and clusters. For all the problems, we present real-world examples and experiments that demonstrate the power of our model, efficiency of our algorithms, and usefulness of their results.

‘The Pinocchio Effect’ – when managing the brand creation process, across cultures

In global marketing and international management, the fields of Branding and Culture are well discussed as separate disciplines; within both academia and industry. However, there appears to be limited supporting literature, examining brands and culture as a collective discipline. In addition, environmental factors such as ethnicity, nationality and religion are also seen to play a significant role. This in itself adds to the challenges encountered, by those looking to critically apply learning and frameworks, to any information gathered. In the first instance, this paper tries to bring aspects together from Branding and Culture and in doing so, aims to find linkages between the two. The main purpose of this paper is to distil current brand thinking and explore what impact cross-cultural, cross-national, and ethnic interactions have on a brand’s creation. The position of the authors is that without further understanding in this field, a brand will experience what has been termed by them as the ‘Pinocchio Effect’. Pinocchio was a puppet who longed to become a real human being; but sadly encountered difficulties. The conclusion presented is that the critical long-term success of a brand lies in three areas: how it is created; the subsequent associated perceptions; and more specifically in the reality of the relationships that it enjoys. Collectively these processes necessitate an appraisal of connecting strategic management procedures and thinking. Finally, this paper looks into proposing future methods for brand evaluation and strategic management. The aim is to stimulate further thinking in a field; which transcends national, ethnic and cultural boundaries - in the interests of developing new insight, and to provide a platform for marketers to develop more effective communications.

Living sustainably: changing cultures and behaviours

2007 was a turning point on what sustainability meant for the construction industry with its new regulation and initiatives. The Government defined sustainability in terms of environmental objectives that can be measured, monitored and met. Last year was also the introduction of the Code for Sustainable Homes. This seminar explores the lessons learnt and the next stage of sustainability in terms of policy and practice.
