RE: pedagogy – after neutrality

Within the UK and in many parts of the world, official accounts of what it is to make sense of religion are framed within a rhetorics of neutrality in which such study is premised upon the possibility of dispassionate engagement and analysis. This paper, which is largely theoretical in scope, explores both the affordances and the costs of such an approach which has become ‘black boxed’ on account of the work that it achieves. A series of new orientations within the academy that are broadly associated with post-structuralist philosophies, feminist and post-colonial studies, together with insights from Science and Technology Studies, question the plausibility of these claims for neutrality whilst in turn raising a series of new questions and priorities. It therefore becomes necessary to re-think and re-frame what it is to make sense of religious and cultural difference after neutrality. The gathering and co-ordination of new planes of sense-making that are responsive to an emergent series of epistemological, ontological, and ethical orientations are considered. Some of the distinctive pedagogical implications of such an approach that engages material practice, difference and uncertainty are then entertained

Registered replication report on Fischer, Castel, Dodd, and Pratt (2003)

The attentional spatial-numerical association of response codes (Att-SNARC) effect (Fischer, Castel, Dodd, & Pratt, 2003)—the finding that participants are quicker to detect left-side targets when the targets are preceded by small numbers and quicker to detect right-side targets when they are preceded by large numbers—has been used as evidence for embodied number representations and to support strong claims about the link between number and space (e.g., a mental number line). We attempted to replicate Experiment 2 of Fischer et al. by collecting data from 1,105 participants at 17 labs. Across all 1,105 participants and four interstimulus-interval conditions, the proportion of times the effect we observed was positive (i.e., directionally consistent with the original effect) was .50. Further, the effects we observed both within and across labs were minuscule and incompatible with those observed by Fischer et al. Given this, we conclude that we failed to replicate the effect reported by Fischer et al. In addition, our analysis of several participant-level moderators (finger-counting habits, reading and writing direction, handedness, and mathematics fluency and mathematics anxiety) revealed no substantial moderating effects. Our results indicate that the Att-SNARC effect cannot be used as evidence to support strong claims about the link between number and space

The Developments in Ethnographic Studies of Organizing: Towards Objects of Ignorance and Objects of Concern

In this introduction to the Special Issue, we review the rich tradition of ethnographic studies in organisation studies and critically examine the place of ethnography in organisation studies as practised in schools of business and management. Drawing on the findings of the articles published here, we reflect on the need for a significant extension of the content and syllabus of our discipline to include what we call objects of concern and objects of ignorance. The articles we publish show that decision makers in organizations are not always humans, and nor can we assume the human and its groups monopolise the capacity for agency in organisation. Where we still labour in organisation theory with dualisms such as structure or agent, or subject and object, these articles trace objects and their relations which point to new forms of non-human co-ordination and agency. The organisational realities to which these objects give rise demand careful methodological enquiry, and we show that recent experiments in a genre we call ‘post-reflexive ethnography’ are likely to prove helpful for developing ethnographic enquiry in contemporary organisation

Visualization and Movement as Configurations of Human-Nonhuman Engagements : Precolonial Geometric Earthwork Landscapes of the Upper Purus, Brazil

Producing geometric designs and images on materials, such as pottery, basketry, and bead artwork, as well as the human body, is elemental and widespread among Amazonian Indigenous peoples. In this article, we examine the different geometric forms identified in the precolonial geoglyph architecture of southwestern Amazonia in the context of geometric design making and relational ontologies. Our aim is to explore earthwork iconography through the lens of Amerindian visual arts and movement. Combining ethnographic and archaeological data from the Upper Purus, Brazil, the article shows how ancient history and socio-cosmology are deeply "written" onto the landscape in the form of geometric earthworks carved out of the soil, which materialize interactions between nonhuman and human actors. We underline skills in visualization, imaginative practices, and movement as ways to promote well-balanced engagements with animated life forms. Here, iconography inserted in the landscape is both a form of writing and also emerges as an agent, affecting people through visual and corporal practices.Peer reviewe

Transfer of gangliosides across the human placenta

Objectives: Gangliosides are structural and functional glycosphingolipids, considered to have important roles in neuronal development in fetal and neonatal development and in memory formation. In this report, we have investigated the ability of bovine milk-derived gangliosides GM3 and GD3 to cross the human placenta. Study design: We have employed the ex-vivo model of dually-perfused isolated human placental lobules. Results: There was significant uptake of both GD3 and GM3 from the maternal perfusate. There was significant increase of GM3 in the fetal side and a non-statistically significant trend for GD3 to increase on the fetal side. Conclusions: Hence an apparent preference for GM3 release into fetal circulation. We suggest that gangliosides consumed by the mother enter her circulation, can be transferred across the placenta and may be available to the developing fetus for building neural connections

Evaluation of Novel Inhibitors of Tryptophan Dioxygenases for Enzyme and Species Selectivity Using Engineered Tumour Cell Lines Expressing Either Murine or Human IDO1 or TDO2

Indoleamine 2, 3-dioxygenase 1 (IDO1) is commonly expressed by cancers as a mechanism for evading the immune system. Preclinical and clinical studies have indicated the potential of combining IDO1 inhibitors with immune therapies for the treatment of cancer, strengthening an interest in the discovery of novel dioxygenase inhibitors for reversing tumour-mediated immune suppression. To facilitate the discovery, development and investigation of novel small molecule inhibitors of IDO1 and its hepatic isozyme tryptophan dioxygenase (TDO2), murine tumour cells were engineered to selectively express either murine or human IDO1 and TDO2 for use as tools to dissect both the species specificity and isoenzyme selectivity of newly discovered inhibitors. Lewis lung carcinoma (LLTC) lines were engineered to express either murine or human IDO1 for use to test species selectivity of the novel inhibitors; in addition, GL261 glioma lines were engineered to express either human IDO1 or human TDO2 and used to test the isoenzyme selectivity of individual inhibitors in cell-based assays. The 20 most potent inhibitors against recombinant human IDO1 enzyme, discovered from a commissioned screening of 40,000 compounds in the Australian WEHI compound library, returned comparable IC50 values against murine or human IDO1 in cell-based assays using the LLTC-mIDO1 and LLTC-hIDO1 line, respectively. To test the in vivo activity of the hits, transfected lines were inoculated into syngeneic C57Bl/6 mice. Individual LLTC-hIDO1 tumours showed variable expression of human IDO1 in contrast to GL261-hIDO1 tumours which were homogenous in their IDO1 expression and were subsequently used for in vivo studies. W-0019482, the most potent IDO1 inhibitor identified from cell-based assays, reduced plasma and intratumoural ratios of kynurenine to tryptophan (K:T) and delayed the growth of subcutaneous GL261-hIDO1 tumours in mice. Synthetic modification of W-0019482 generated analogues with dual IDO1/TDO2 inhibitory activity, as well as inhibitors that were selective for either TDO2 or IDO1. These results demonstrate the versatility of W-0019482 as a lead in generating all three subclasses of tryptophan dioxygenase inhibitors which can be applied for investigating the individual roles and interactions between IDO1 and TDO2 in driving cancer-mediated immune suppression

Synthesis and Biological Activity of Azido Analogues of 5,6-Dimethylxanthenone-4-acetic Acid for Use in Photoaffinity Labeling

5,6-Dimethylxanthenone-4-acetic acid (1) is scheduled for phase III clinical trials as a vascular disrupting agent. However, its biochemical receptor(s) have yet to be identified. In this report, the synthesis of azido analogues of 1 that could be used for photoaffinity labeling of proteins as an approach toward identifying its molecular targets is described. While 5-azidoxanthenone-4-acetic acid (2) and 5-azido-6-methylxantheone-4-acetic acid (3) were found to have biological activities similar to that of 1, 6-azido-5-methylxanthenone-4-acetic acid (4) was unstable and could not be evaluated. Both azido compounds 2 and 3 activated NF-kappaB, induced the production of tumor necrosis factor in cultured mouse splenocytes, and induced hemorrhagic necrosis of colon 38 tumors in mice. Photoreaction of lysates from spleen cells with tritiated 2 resulted in two radiolabeled protein bands at 50 and 14 kDa that could be competitively inhibited with cold 1 and cold 2. The azido compounds 2 and 3 exhibit all the requirements for use in photoaffinity labeling of potential receptor(s) for 1
