Bourdieu's non-material forms of capital:Implications for start-up policy

The role of Bourdieu’s non-material forms of capital (cultural, social and symbolic) in the entrepreneurial process has received little dedicated research attention. Similarly, the link between occupationally distinct entrepreneurship and accumulation of non-material capitals is understudied. Addressing this, we examine the non-material capitals of different nascent entrepreneurs by occupational classification who participated on two enterprise-training programmes funded by the 1997-2010 Labour Government; each with considerably different foci. Findings demonstrate that professional and higher technician entrepreneurs possess valuable non-material capitals, in contrast to non-professional entrepreneurs. Against the backdrop of recent business enterprise policy, findings suggest that policy-makers should prioritise focused support that nurtures the valuable, productive non-material capitals of professional and higher technician entrepreneurs. Furthermore, initiatives should be tailored to improve the less distinguished non-material capitals of non-professional entrepreneurs

Women and power: a theoretical approach using the example of copreneurial businesses

Despite the gradual recognition of strategic issues related to the integration of women into the economy, female entrepreneurship continues to receive little attention. Family business research attributes this situation to a lack of recognition given to the (decisive) role of women in these organizations. However, there is one type of family governance that formally acknowledges the man/woman combination: the copreneurial company. Copreneurs are couples who run a business together. This theoretical article highlights the role of women in the copreneurial context by distinguishing between formal and informal power- the latter being primarily held by women, but which is no less influential. The distribution of power reduces opposition costs between partners and the social costs of non-compliance, and improves the clarity of the entrepreneurial structure. Moreover, it increases satisfaction and a feeling of equality between the partners. These results can be generalized and shed light on the role of women in other entrepreneurial and social contexts. This article is published as part as part of a collection on the role of women in management and business

A readily-accessible (+)-sparteine surrogate

A “(+)-sparteine-like” chiral diamine, readily synthesized in three steps from (−)-cytisine, has been evaluated in four different asymmetric transformations; in each case, selectivity in an enantiocomplementary fashion to (−)-sparteine was observed

Relation of risk of systemic lupus erythematosus to west African admixture in a Caribbean population.

Risk of systemic lupus erythematosus (SLE) is higher in people of west African descent than in Europeans. The objective of this study was to distinguish between genetic and environmental explanations for this ethnic difference by examining the relationship of disease risk to individual admixture (defined as the proportion of the genome that is of west African ancestry); 124 cases of SLE and 219 matched controls resident in Trinidad were studied. Analysis of admixture was restricted to 52 cases and 107 controls who reported no Indian or Chinese ancestry. These individuals were typed with a panel of 26 single-nucleotide polymorphisms and five insertion/deletion polymorphisms chosen to have large allele frequency differentials between west African, European and Native American populations. A Bayesian model for population admixture, individual admixture and locus ancestry was fitted by Markov chain simulation. Mean west African admixture (M) was 0.81 in cases and 0.74 in controls (P=0.01). The risk ratio for SLE associated with unit change in M was estimated as 32.5 with a 95% confidence interval (CI) of 2.0-518. Adjustment for measures of socioeconomic status (household amenities in childhood and years of education) altered this risk ratio only slightly (adjusted risk ratio: 28.4, 95% CI 1.7-485). These results support an additive genetic model for the ethnic difference in risk of SLE between west Africans and Europeans, rather than an environmental explanation or an "overdominant" model in which risk is higher in heterozygous than in homozygous individuals. This conclusion lays a basis for localizing the genes underlying this ethnic difference in risk of SLE by admixture mapping
