    Valuing precarious commodities : an ethnography of trade in three charity shops in the Cape Metropolitan area

    Thesis (MA)--Stellenbosch University, 2014.ENGLISH ABSTRACT: In this study I investigate how the value of factory manufactured second-hand objects is determined within three charity shops in the Cape Metropolitan area. I argue that the value of the second-hand object sold in the charity shop cannot be determined solely from the quantifiable abstract labour of its 'initial production', or the perceived depreciation thereof. Nor can it be ascribed to the meanings produced in exchange. Instead I propose the histories of use and biographies of the objects in conjunction with the expectations of charity that emerge within the charity shop render them 'precarious commodities'. The value of the precarious charity shop commodity is informed by the socio-spatial conditions inside and outside the charity shops that, I suggest, propagate racial nostalgias from which notions of 'expensive respectability' and the middle class emerge as valuing. Within these conditions the charity shop acts as a point of production, in which staff labour to reconstitute value and transform donated objects into resalable commodities. These labours include the purging, sorting and distribution of objects in the 'back-space' of each shop and the commodity aesthetics of the 'front-spaces'. This labour is not limited to sellers; buyers also negotiate the dynamics of value within the 'front-space' of the charity shop, drawing upon similar notions of racialized respectability as they seek out 'quality' shopping experiences and engage in 'treasure hunting' and 'aspirational shopping'.AFRIKAANSE OPSOMMING: In hierdie studie het ek ondersoek hoe waarde bepaal word binne drie liefdadigheid winkels in die Kaapse Metropool. Ek argumenteer dat die waarde van die tweedeHande liefdadigheid voorwerpe wat verkoop word in die liefdadigheid‘s winkel kan nie uitsluitlik bepaal word van die kwantifiseerbare abstrakte arbeid van die voorwerp se 'aanvanklike produksie', of die vermeende waardevermindering daarvan bepaal nie. Dit kan ook nie toegeskryf word aan die betekenis wat in ruil geproduseer is nie, omdat die voorwerpe wat op die spel is reeds onderhewig aan gebruik en die spesifieke verwagtinge van liefdadigheid wat na vore kom in die liefdadigheid‘s winkel. Verder illustreer ek dat waarde bepaal word deur die sosio-ruimtelike omstandighede binne en buite die winkels. Hierdie toestande, stel ek voor, propageer rasse nostalgie waaruit 'n bepaalde rasse tipe, 'n 'duur ordentlikheid' na vore kom as waardering. Ek argumenteer dat liefdadigheid winkels tree op as punte van produksie en transformeer geskenkde voorwerpe in haglike-kommoditeite deur arbeid wat nastreef om gebruik-waarde, die vervaardiging van die kommoditeit estetika en verkoop van die voorwerp te versterk. Hierdie arbeid is nie beperk tot verkopers nie, ek wys dat kopers maak gebruik van soortgelyke rasgedrewe opvattings van kwaliteit terwyl hulle die dinamika van waarde binne die liefdadigheid winkel onderhandel

    “The big wide world of school”: Supporting children on the autism spectrum to successfully transition to primary school: Perspectives from parents and early intervention professionals

    Get PDF
    Background: The transition to primary school is often a complex and uncertain time for autistic children and their families. Understanding how best to develop school readiness and support transition to primary school for autistic children is essential. School readiness and transition planning are influenced by a range of personal and contextual factors, and it is important to understand the perspectives of the various stakeholders involved in the transition process. Methods: A qualitative exploration employing focus groups and interviews was undertaken with early intervention (EI) staff (n = 45) and parents (n = 18) across Australia to understand their perspectives on school readiness and the transition to primary school. Results: Thematic analysis identified four emerging themes facilitating transition including: 1) building the child; 2) building the parents; 3) building the receiving school; and, 4) connecting the system. Conclusion: Findings highlight the need to consider school readiness and transition planning from a holistic perspective, ensuring clear, collaborative and ongoing communication between parents, teachers and EI staff, using a strength-based approach, and individualizing transition planning

    Association of Maternal Antiangiogenic Profile at Birth With Early Postnatal Loss of Microvascular Density in Offspring of Hypertensive Pregnancies

    Offspring of hypertensive pregnancies are more likely to have microvascular rarefaction and increased blood pressure in later life. We tested the hypothesis that maternal angiogenic profile during a hypertensive pregnancy is associated with fetal vasculogenic capacity and abnormal postnatal microvascular remodeling. Infants (n=255) born after either hypertensive or normotensive pregnancies were recruited for quantification of postnatal dermal microvascular structure at birth and 3 months of age. Vasculogenic cell potential was assessed in umbilical vein endothelial cells from 55 offspring based on in vitro microvessel tube formation and proliferation assays. Maternal angiogenic profile (soluble fms-like tyrosine kinase-1, soluble endoglin, vascular endothelial growth factor, and placental growth factor) was measured from postpartum plasma samples to characterize severity of pregnancy disorder. At birth, offspring born after hypertensive pregnancy had similar microvessel density to those born after a normotensive pregnancy, but during the first 3 postnatal months, they had an almost 2-fold greater reduction in total vessel density (−17.7±16.4% versus −9.9±18.7%; P=0.002). This postnatal loss varied according to the vasculogenic capacity of the endothelial cells of the infant at birth (r=0.49; P=0.02). The degree of reduction in both in vitro and postnatal in vivo vascular development was proportional to levels of antiangiogenic factors in the maternal circulation. In conclusion, our data indicate that offspring born to hypertensive pregnancies have reduced vasculogenic capacity at birth that predicts microvessel density loss over the first 3 postnatal months. Degree of postnatal microvessel reduction is proportional to levels of antiangiogenic factors in the maternal circulation at birth.Hypertension is published on behalf of the American Heart Association, Inc., by Wolters Kluwer.

    Prospective observational cohort study on grading the severity of postoperative complications in global surgery research

    Background The Clavien–Dindo classification is perhaps the most widely used approach for reporting postoperative complications in clinical trials. This system classifies complication severity by the treatment provided. However, it is unclear whether the Clavien–Dindo system can be used internationally in studies across differing healthcare systems in high- (HICs) and low- and middle-income countries (LMICs). Methods This was a secondary analysis of the International Surgical Outcomes Study (ISOS), a prospective observational cohort study of elective surgery in adults. Data collection occurred over a 7-day period. Severity of complications was graded using Clavien–Dindo and the simpler ISOS grading (mild, moderate or severe, based on guided investigator judgement). Severity grading was compared using the intraclass correlation coefficient (ICC). Data are presented as frequencies and ICC values (with 95 per cent c.i.). The analysis was stratified by income status of the country, comparing HICs with LMICs. Results A total of 44 814 patients were recruited from 474 hospitals in 27 countries (19 HICs and 8 LMICs). Some 7508 patients (16·8 per cent) experienced at least one postoperative complication, equivalent to 11 664 complications in total. Using the ISOS classification, 5504 of 11 664 complications (47·2 per cent) were graded as mild, 4244 (36·4 per cent) as moderate and 1916 (16·4 per cent) as severe. Using Clavien–Dindo, 6781 of 11 664 complications (58·1 per cent) were graded as I or II, 1740 (14·9 per cent) as III, 2408 (20·6 per cent) as IV and 735 (6·3 per cent) as V. Agreement between classification systems was poor overall (ICC 0·41, 95 per cent c.i. 0·20 to 0·55), and in LMICs (ICC 0·23, 0·05 to 0·38) and HICs (ICC 0·46, 0·25 to 0·59). Conclusion Caution is recommended when using a treatment approach to grade complications in global surgery studies, as this may introduce bias unintentionally
