Going global with assessment: what to do when the dominant culture's literacy drives assessment

This article explores how the dominant cultural literacy in a western context relies on a western template of knowledge that can inhibit internationalisation of the curricula unless it is identified, transformed, and broadened to become interculturally responsive. As Brian Street has said "literacies may be sites of negotiation and transform ation" (1994, p. 99). Drawing on the findings of an innovative website, Worldmarks , developed at Queensland University of Technology, as well as qualitative interviews with international students and staff, this article addresses the serious implications of assessment driven by the dominant culture's literacy. We identify how and why assessment driven by responsive cultural literacy enables all students to develop comprehensive intercultural communication skills and understandings as part of their lifelong learning in Australian universities.

Cortisol, DHEA, performance and training in elite swimmers

Salivary cortisol (C) and DHEA concentrations were measured in 9 elite swimmers (4 female and 5 male) over a 37-week period, 5 to 12 times per swimmer, before 68 competitions. For female and male swimmers, no significant relationship was found between C, DHEA and performance. For the whole group, C was negatively correlated with week number of training (r = -0.31, p < 0.01). The incorporation of the cumulated distance swum as a second variable in the regression increased r to 0.56 (p < 0.01). The higher the cumulated distance swum, the higher C. No significant relationship was found between DHEA and distance swum. For individual swimmers, 3 of 4 females showed a significant negative relationship between C and cumulated dry-land training. No equivalent relationship was found for DHEA. The 2 males practicing dry-land training showed a significant and negative relationship between DHEA and cumulated dry-land training. No equivalent relationship was found for C. Thus, C and DHEA were not good predictors of swimming performance. C for individual females, and DHEA for individual males were considered useful markers for dry-land training stress.

The effect of Yb addition in Bi2Sr2Ca1-x,YbxU2Oy partial melted thick films

To study the phase relations in the Bi-2212 and Yb2O3 system, Bi2Sr2Ca1-xYbxCu2Oy thick films are prepared by partial melt processing via an intermediate reaction between Bi-2212 and Yb2O3. When Bi-2212 and Yb2O3 are partially melted and then slowly cooled, solid solutions of Bi2Sr2Ca1-xYbxCu2Oy form by reactions between liquid and solid phases which contain Yb. Following these reactions, Ca is partially replaced in Bi-2212 matrix and participates in the formation of secondary phases, such as Bi-free, (Ca, Sr)O-x and CaO. Variation of the Bi-2212-Yb2O3 ratios and processing parameters changes the balance between the phases and leads to different Yb:Ca ratios in the Bi-2212 matrix of processed thick films. When the partial melting process is optimized for each sample to minimize the growth of secondary phases, x = 0.42-0.46 for the samples prepared at pO(2) = 0.01 atm, x = 0.24-0.29 for the samples prepared at pO(2) = 0.21 atm, x = 0.18-0.23 for the samples prepared at pO(2) = 0.99 atm are obtained regardless to the starting compositions. It is found that superconducting properties of Bi2Sr2Ca1-xYbxCu2Oy thick films strongly depend on the processing conditions, because the conditions result in different Yb content in the Bi-2212 matrix and the volume fraction of the secondary phases. The highest T-c(0) of 77, 90 and 91 K were obtained for the samples processed at 0.01, 0.21 and 0.99 atm of O-2, respectively.

Leukocyte subset responses during exercise under heat stress with carbohydrate or water intake

Purpose: This study investigated leukocyte subset responses to moderate-intensity exercise under heat stress, with water (W) or carbohydrate (CHO) drink ingestion. Methods: In repeated trials, 13 soldiers consumed either a W or CHO drink during 3 h of walking at 4.4 km center dot h(-1) with a 5% gradient (15 min rest per hour) under heat stress (35 C and 55% relative humidity). The soldiers wore combat uniforms and carried water bottles and dummy rifles and ammunition, altogether weighing about 11.5 +/- 1.0 kg. Results: Plasma glucose concentration was significantly higher with CHO than W ingestion during exercise (p < 0.01). There were no significant differences between W and CHO conditions in exercise performance, plasma cortisol concentration, heart rate, or core temperature. CHO ingestion significantly moderated the increases in leukocyte (83% in W, 28% in CHO; p < 0.001), monocyte (60% in W, 34% in CHO; p < 0.05), and granulocyte counts (120% in W, 30% in CHO; p < 0.001), but not in lymphocyte count (41% in W, 25% in CHO). Conclusions: The increases in leukocyte and subset counts during moderate-intensity exercise under heat stress may be comparable to those observed during intense exercise in cool conditions. The response of immune cell counts is blunted by CHO intake during moderate-intensity exercise in the heat, and may not occur through the cortisol pathway.

Carbohydrate supplementation and alterations in neutrophils, and plasma cortisol and myoglobin concentration after intense exercise

The present study examined the effect of carbohydrate supplementation on changes in neutrophil counts, and the plasma concentrations of cortisol and myoglobin after intense exercise. Eight well-trained male runners ran on a treadmill for 1 h at 85% maximal oxygen uptake on two separate occasions. In a double-blind cross-over design, subjects consumed either 750 ml of a 10% carbohydrate (CHO) drink or a placebo drink on each occasion. The order of the trials was counterbalanced. Blood was drawn immediately before and after exercise, and I h after exercise. Immediately after exercise, neutrophil counts (CHO, 49%; placebo, 65%; P < 0.05), plasma concentrations of glucose (CHO, 43%; P

Small-scale randomized controlled trials need more powerful methods of mediational analysis than the Baron-Kenny method

Objective: To devise more-effective physical activity interventions, the mediating mechanisms yielding behavioral change need to be identified. The Baron-Kenny method is most commonly used. but has low statistical power and May not identify mechanisms of behavioral change in small-to-medium size Studies. More powerful statistical tests are available, Study Design and Setting: Inactive adults (N = 52) were randomized to either a print or a print-plus-telephone intervention. Walking and exercise-related social support Were assessed at baseline, after file intervention, and 4 weeks later. The Baron-Kenny and three alternative methods of mediational analysis (Freedman-Schatzkin; MacKinnon et al.: bootstrap method) were used to examine the effects of social support on initial behavior change and maintenance. Results: A significant mediational effect of social support on initial behavior change was indicated by the MacKinnon et al., bootstrap. and. marginally. Freedman-Schatzkin methods, but not by the Baron-Kenny method. No significant mediational effecl of social support on maintenance of walking was found. Conclusions: Methodologically rigorous intervention studies to identify mediators of change in physical activity are costly and labor intensive, and may not be feasible with large samples. The Use of statistically powerful tests of mediational effects in small-scale studies can inform the development of more effective interventions. (C) 2006 Elsevier Inc. All rights reserved.

The roles of exercise-induced immune system disturbances in the pathology of heat stroke - The dual pathway model of heat stroke

Heat stroke is a life-threatening condition that can be fatal if not appropriately managed. Although heat stroke has been recognised as a medical condition for centuries, a universally accepted definition of heat stroke is lacking and the pathology of heat stroke is not fully understood. Information derived from autopsy reports and the clinical presentation of patients with heat stroke indicates that hyperthermia, septicaemia, central nervous system impairment and cardiovascular failure play important roles in the pathology of heat stroke. The current models of heat stroke advocate that heat stroke is triggered by hyperthermia but is driven by endotoxaemia. Endotoxaemia triggers the systemic inflammatory response, which can lead to systemic coagulation and haemorrhage, necrosis, cell death and multi-organ failure. However, the current heat stroke models cannot fully explain the discrepancies in high core temperature (Tc) as a trigger of heat stroke within and between individuals. Research on the concept of critical Tc: as a limitation to endurance exercise implies that a high Tc may function as a signal to trigger the protective mechanisms against heat stroke. Athletes undergoing a period of intense training are subjected to a variety of immune and gastrointestinal (GI) disturbances. The immune disturbances include the suppression of immune cells and their functions, suppression of cell-mediated immunity, translocation of lipopolysaccharide (LPS), suppression of anti-LPS antibodies, increased macrophage activity due to muscle tissue damage, and increased concentration of circulating inflammatory and pyrogenic cytokines. Common symptoms of exercise-induced GI disturbances include diarrhoea, vomiting, gastrointestinal bleeding, and cramps, which may increase gut-related LPS translocation. This article discusses the current evidence that supports the argument that these exercise-induced immune and GI disturbances may contribute to the development of endotoxaemia and heat stroke. When endotoxaemia can be tolerated or prevented, continuing exercise and heat exposure will elevate Tc to a higher level (> 42 degrees C), where heat stroke may occur through the direct thermal effects of heat on organ tissues and cells. We also discuss the evidence suggesting that heat stroke may occur through endotoxaemia (heat sepsis), the primary pathway of heat stroke, or hyperthermia, the secondary pathway of heat stroke. The existence of these two pathways of heat stroke and the contribution of exercise-induced immune and GI disturbances in the primary pathway of heat stroke are illustrated in the dual pathway model of heat stroke. This model of heat stroke suggests that prolonged intense exercise suppresses anti-LPS mechanisms, and promotes inflammatory and pyrogenic activities in the pathway of heat stroke.

Conservation and accessibility of an inner core lipopolysaccharide epitope of Neisseria meningitidis

We investigated the conservation and antibody accessibility of inner core epitopes of Neisseria meningitidis lipopolysaccharide (LPS) because of their potential as vaccine candidates. An immunoglobulin G3 murine monoclonal antibody (MAb), designated MAb B5, was obtained by immunizing mice with a galE mutant of N. meningitidis H44/76 (B.15.P1.7,16 immunotype L3). We have shown that MAb B5 can bind to the core LPS of wild-type encapsulated MC58 (B.15.P1.7,16 immunotype L3) organisms in vitro and ex vivo. An inner core structure recognized by MAb B5 is conserved and accessible in 26 of 34 (76%) of group B and 78 of 112 (70%) of groups A, C, W, X, Y, and Z strains. N. meningitidis strains which possess this epitope are immunotypes in which phosphoethanolamine (PEtn) is linked to the 3-position of the beta-chain heptose (HepII) of the inner core. In contrast, N. neningitidis strains lacking reactivity with MAb B5 have an alternative core structure in which PEtn is linked to an exocyclic position (i.e., position 6 or 7) of HepII (immunotypes L2, L4, and L6) or is absent (immunotype L5). We conclude that MAb B5 defines one or more of the major inner core glycoforms of N. meningitidis LPS. These findings support the possibility that immunogens capable of eliciting functional antibodies specific to inner core structures could be the basis of a vaccine against invasive infections caused by N. meningitidis.

'Worldmarks': Web guidelines for socially and culturally responsive assessment in university classrooms

In the early 21st century, we need to prepare university students to navigate local and global cultures effectively and sensitively. These future professionals must develop comprehensive intercultural communication skills and understanding. Yet university assessment in Australia is often based on a western template of knowledge, which automatically places International, Indigenous, as well as certain groups of local students at a study disadvantage. It also ensures that Australian students from dominant groups are not given the opportunity to develop these vital intercultural skills. This paper explores the issues embedded in themes 1 and 4 of this conference and provides details of an innovative website developed at Queensland University of Technology in Brisbane, Australia, which encourages academic staff to investigate the hidden assumptions that can underpin their assessment practices. The website also suggests strategies academics can use to ensure that their assessment becomes more socially and culturally responsive.

DIVINDADES MLK E CULTO A MOLEK NOS QUADROS DA CRISE RELIGIOSA NO FINAL DA MONARQUIA DE JUDÁ (2 Reis 16,3; 17,17.31; 21,6; 23,10; KTU 1.100; 1.118; 1.161)

A dissertação é dirigida a um especial e não resolvido problema na descrição do desenvolvimento religioso de Israel. Em textos do Antigo Testamento acerca do sacrifício de humanos, há uma unidades literárias autônomas relacionadas ao culto a mOlek. Porém, alguns pesquisadores sustentam que o culto a mOlek não tem esta característica. A dissertação aspira a investigar este argumento, concentrando-se em fontes históricas (2Reis 16,3; 17,17.31; 21,6; 23,10). Discutindo fontes ugaríticas duas listas de divindades e um texto funerário nós perguntares acerca das características das divindades mLlK nas culturas cananéias. Em síntese, mOlek é uma divindade ctônica mas não é destinatária de sacrifícios humanos.(AU)

DISCURSOS E PRÁTICAS FUNDAMENTALISTAS NA IGREJA PRESBITERIANA DO BRASIL (2002-2008) UMA ANÁ-LISE DA PRETENSA POSIÇÃO DE EQÜIDISTÂNCIA DOS EXTREMOS FUNDAMENTALISTAS E LIBERAIS

Em diversas ocasiões, os líderes da Igreja Presbiteriana do Brasil revelaram o desejo de uma eqüidistância teológica dos extremos liberais e fundamentalistas. Entretanto, os dis-cursos e as práticas dessa instituição eclesiástica contrastam com esse posicionamento ofici-al. Além disso, essa pretensa posição de eqüidistância dos extremos liberais e fundamenta-listas não denota fronteiras rígidas, mas é um instrumento eficaz de legitimação do poder nos momentos de reconfiguração do campo religioso, principalmente em situações de crises internas. Outrossim, após a redemocratização do Brasil e o conseqüente aumento de plura-lismo religioso, houve a transformação do campo social brasileiro, provocando dificuldades em setores mais conservadores dessa instituição. Atualmente, procura-se revitalizar a pró-pria tradição religiosa diante das ameaças de sua dissolução impostas pelos processos e-mancipatórios modernos e pela influência das concepções seculares e supostamente atéias da vida (como o feminismo, a luta em defesa dos direitos reprodutivos, a união civil entre pessoas do mesmo sexo, o chamado ―movimento de lésbicas, gays, bissexuais, travestis e transgêneros‖ etc.). No campo religioso, os resultados imediatos dessa postura de reação em face das transformações sociais impostas pela modernidade são: (1) misoginia; (2) aquela manifestação de ativismo político-religioso de caráter conservador os protestantes de pen-dor fundamentalista, cuja expansão no Brasil se vem processando há muitas décadas, em ritmo sabidamente veloz, com base em um modelo de proselitismo muito bem-sucedido entre as camadas mais pobres da população brasileira, por todo território nacional.(AU)
