Transients and asymptotics of natural gradient learning

We analyse natural gradient learning in a two-layer feed-forward neural network using a statistical mechanics framework which is appropriate for large input dimension. We find significant improvement over standard gradient descent in both the transient and asymptotic phases of learning

Mobile phones and entrepreneurial identity negotiation by urban female street traders in Uganda

Mobile phones have been posited as enhancing women's entrepreneurship and gender equality in developing countries, yet empowerment outcomes are unclear. This article considers how women in the gender-segregated informal economy construct their entrepreneurial identity in relation to mobile phones and the discursive repertoires that marginalize and empower. Using data from interviews with six urban female street traders in Kampala, Uganda, it explores how these repertoires illustrate their sense of self, positioning and belonging to the business community. Normative representations and positioning of female traders can sideline entrepreneurial identity and over-validate gender identity. But, participants also negotiate entrepreneurial identity construction in response to these marginalizing influences. Although the data demonstrate that participants are equivocal about their entrepreneurial identity or fit in business, some representations are more validating and offer a sense of belonging. The article concludes by highlighting the nuanced opportunities for social change their discursive repertoires may present

Women’s entrepreneurship policy research : a 30-year review of the evidence

This paper focuses on women’s entrepreneurship policy as a core component of the entrepreneurial ecosystem. We use a systematic literature review (SLR) approach to critically explore the policy implications of women’s entrepreneurship research according to gender perspective: feminist empiricism, feminist standpoint theory, and post-structuralist feminist theory. Our research question asks whether there is a link between the nature of policy implications and the different theoretical perspectives adopted, and whether scholars’ policy implications have changed as the field of women’s entrepreneurship research has developed. We concentrate on empirical studies published in the “Big Five” primary entrepreneurship research journals (SBE, ETP, JBV, JSBM, and ERD) over a period of more than 30 years (1983–2015). We find that policy implications from women’s entrepreneurship research are mostly vague, conservative, and center on identifying skills gaps in women entrepreneurs that need to be “fixed,” thus isolating and individualizing any perceived problem. Despite an increase in the number of articles offering policy implications, we find little variance in the types of policy implications being offered by scholars, regardless of the particular theoretical perspective adopted, and no notable change over our 30-year review period. Recommendations to improve the entrepreneurial ecosystem for women from a policy perspective are offered, and avenues for future research are identified
