Negotiating networks of self-employed work: strategies of minority ethnic contractors

Within the increased flexible, contracted work in cities, employment is negotiated through network arrangements characterised by multiplicity, mobility and fluidity. For black and minority ethnic group members, this network labour becomes fraught as they negotiate both their own communities, which can be complex systems of conflicting networks, as well as non-BME networks which can be exclusionary. This discussion explores the networking experiences of BME individuals who are self-employed in portfolio work arrangements in Canada. The analysis draws from a theoretical frame of ‘racialisation’ (Mirchandani and Chan, 2007) to examine the social processes of continually constructing and positioning the Other as well as the self through representations in these networks. These positions and concomitant identities enroll BME workers in particular modes of social production, which order their roles and movement in the changing dynamics of material production in networked employment

Evidence of negative energy balance using doubly labelled water in elite Kenyan endurance runners prior to competition

Previous studies have found Kenyan endurance runners to be in negative energy balance during training and prior to competition. The aim of the present study was to assess energy balance in nine elite Kenyan endurance runners during heavy training. Energy intake and expenditure were determined over 7d using weighed dietary intake and doubly labelled water, respectively. Athletes were on average in negative energy balance (mean energy intake 13 241 (SD 1330) kJ/d v. mean energy expenditure 14 611 (SD 1043) kJ/d; P=0·046), although there was no loss in body mass (mean 56·0 (SD 3·4) kg v. 55·7 (SD 3·6) kg; P=0·285). The calculation of underreporting was 13; (range −24 to +9%) and almost entirely accounted for by undereating (9% (range −55 to +39%)) as opposed to a lack of significant underrecording (i.e. total water intake was no different from water loss (mean 4·2 (SD 0·6) l/d v. 4·5 (SD 0·8) l/d; P=0·496)). Fluid intake was modest and consisted mainly of water (0·9 (SD 0·5) l/d) and milky tea (0·9 (SD 0·3) l/d). The diet was high in carbohydrate (67·3 (SD 7·8) %) and sufficient in protein (15·3 (SD 4·0) %) and fat (17·4 (SD 3·9) %). These results confirm previous observations that Kenyan runners are in negative energy balance during periods of intense training. A negative energy balance would result in a reduction in body mass, which, when combined with a high carbohydrate diet, would have the potential in the short term to enhance endurance running performance by reducing the energy cost of runnin

'Some people are not allowed to love': intimate citizenship in the lives of people labelled with intellectual disabilities

Disability helps us think differently about the ‘ideal’ neoliberal-able citizen who may not equate to ideas of productive, sexual, ‘normal’. Intimate citizenship – our rights and access to intimacy – is often ignored by those working with people labelled with intellectual disabilities and in research. In this article, we discuss the outcome of a dialogue between self-advocates labelled with intellectual disabilities, academics, service providers, Aboriginal leaders, students and artists about intimate citizenship through love, intimate work and consumption

The Future of the Standard Employment Relationship: Labour Law, New Institutional Economics and Old Power Resource Theory

This article addresses two questions about the standard employment relationship that have become prominent in labour law literature: Does it exacerbate inequality? Is its decline inevitable? The focus is on the second question and emphasizes the extent to which the standard employment relationship was both embedded in, and the outcome of, an institutional ensemble that was fashioned out of the post-war capital–labour compromise in industrialized democracies. The analysis proceeds in three steps. The first is conceptual and stresses the distinctive nature of labour as a fictive commodity, and the recurring regulatory dilemmas that arise in any attempt to institutionalize a labour market. The second step historicizes and contextualizes the employment relationship, emphasizing politics and conflict (power resource theory) over rational choice and coordination (new institutional economics) as the basis for its institutionalization. The emphasis on politics, power and labour leads to the third step, which focuses on how the broad process of financialization influences three key institutions – the large manufacturing firm, the democratic welfare state and autonomous trade unions – that have been crucial for the development of the standard employment relationship

Modern Slavery, Unfree Labour and the Labour Market: The Social Dynamics of Legal Characterization

Treating the United Kingdom’s Modern Slavery Act as its focus, this article examines what the legal characterization of labour unfreedom reveals about the underlying conception of the labour market that informs contemporary approaches to labour law in the United Kingdom. It discusses how unfree labour is conceptualized within two key literatures – Marxist-inspired political economy and liberal approaches to modern slavery – and their underlying assumptions of the labour market and how it operates. As an alternative to these depictions of the labour market, it proposes a legal institutionalist or constitutive account. It develops an approach to legal characterization and jurisdiction that is attentive to modes of governing and the role of political and legal differentiation both in producing labour exploitation and unfree labour and in developing strategies for its elimination. It argues that the problem with the modern slavery approach to unfree labour is that it tends to displace labour law as the principal remedy to the problem of labour abuse and exploitation, while simultaneously reinforcing the idea that flexible labour markets of the type that prevails in the United Kingdom are realms of labour freedom

Sucrose activates human taste pathways differently from artificial sweetener

Animal models suggest that sucrose activates taste afferents differently than non-caloric sweeteners. Little information exists how artificial sweeteners engage central taste pathways in the human brain. We assessed sucrose and sucralose taste pleasantness across a concentration gradient in 12 healthy control women and applied 10% sucrose and matched sucralose during functional magnet resonance imaging. The results indicate that (1) both sucrose and sucralose activate functionally connected primary taste pathways; (2) taste pleasantness predicts left insula response; (3) sucrose elicits a stronger brain response in the anterior insula, frontal operculum, striatum and anterior cingulate, compared to sucralose; (4) only sucrose, but not sucralose, stimulation engages dopaminergic midbrain areas in relation to the behavioral pleasantness response. Thus, brain response distinguishes the caloric from the non-caloric sweetener, although the conscious mind could not. This could have important implications on how effective artificial sweeteners are in their ability to substitute sugar intake

TMEFF2 Is a PDGF-AA Binding Protein with Methylation-Associated Gene Silencing in Multiple Cancer Types Including Glioma

BACKGROUND: TMEFF2 is a protein containing a single EGF-like domain and two follistatin-like modules. The biological function of TMEFF2 remains unclear with conflicting reports suggesting both a positive and a negative association between TMEFF2 expression and human cancers. METHODOLOGY/PRINCIPAL FINDINGS: Here we report that the extracellular domain of TMEFF2 interacts with PDGF-AA. This interaction requires the amino terminal region of the extracellular domain containing the follistatin modules and cannot be mediated by the EGF-like domain alone. Furthermore, the extracellular domain of TMEFF2 interferes with PDGF-AA-stimulated fibroblast proliferation in a dose-dependent manner. TMEFF2 expression is downregulated in human brain cancers and is negatively correlated with PDGF-AA expression. Suppressed expression of TMEFF2 is associated with its hypermethylation in several human tumor types, including glioblastoma and cancers of ovarian, rectal, colon and lung origins. Analysis of glioma subtypes indicates that TMEFF2 hypermethylation and decreased expression are associated with a subset of non-Proneural gliomas that do not display CpG island methylator phentoype. CONCLUSIONS/SIGNIFICANCE: These data provide the first evidence that TMEFF2 can function to regulate PDGF signaling and that it is hypermethylated and downregulated in glioma and several other cancers, thereby suggesting an important role for this protein in the etiology of human cancers
