    The Performance of Private Equity Funds: Does Diversification Matter?

    Get PDF
    This paper is the first systematic analysis of the impact of diversification on the performance of private equity funds. A unique data set allows the exact evaluation of diversification across the dimensions financing stages, industries, and countries. Very different levels of diversification can be observed across sample funds. While some funds are highly specialized others are highly diversified. The empirical results show that the rate of return of private equity funds declines with diversification across financing stages, but increases with diversification across industries. Accordingly, the fraction of portfolio companies which have a negative return or return nothing at all, increase with diversification across financing stages. Diversification across countries has no systematic effect on the performance of private equity funds

    A terminal assessment of stages theory : introducing a dynamic states approach to entrepreneurship

    Get PDF
    Stages of Growth models were the most frequent theoretical approach to understanding entrepreneurial business growth from 1962 to 2006; they built on the growth imperative and developmental models of that time. An analysis of the universe of such models (N=104) published in the management literature shows no consensus on basic constructs of the approach, nor is there any empirical confirmations of stages theory. However, by changing two propositions of the stages models, a new dynamic states approach is derived. The dynamic states approach has far greater explanatory power than its precursor, and is compatible with leading edge research in entrepreneurship

    Constructing female entrepreneurship policy in the UK : is the US a relevant benchmark?

    Get PDF
    Successive UK governments have introduced a range of policy initiatives designed to encourage more women to start new firms. Underpinning these policies has been an explicit ambition for the UK to achieve similar participation rates as those in the US where it is widely reported that women own nearly half the stock of businesses. The data underlying these objectives are critically evaluated and it is argued that the definitions and measures of female enterprise used in the UK and the US restrict meaningful comparisons between the two. It is suggested that the expansion of female entrepreneurship in the US is historically and culturally specific to that country. UK policy goals should reflect the national socioeconomic context, while drawing upon good practice examples from a range of other countries. The paper concludes by discussing the economic and social viability of encouraging more women in the UK to enter self-employment without fully recognising the intensely competitive sectors in which they are often located

    Unique chemical parameters and microbial activity lead to increased archaeological preservation at the Roman frontier site of Vindolanda, UK.

    Waterlogged burial conditions impact upon artefact preservation. One major determinant of preservation is presence and behaviour of microorganisms, however, unravelling the mechanisms, especially in waterlogged conditions is challenging. In this study, we analysed elemental composition, bacterial diversity and community structure from excavation trenches at the Roman Site of Vindolanda, Northumberland, UK, using pXRF and 16S rRNA gene amplicon sequencing. Excavation trenches provide information of different occupation periods. The results indicated that microbial communities were dominated by Firmicutes, Bacteroidetes and Proteobacteria at a phylum level. Samples which also had visible vivianite presence showed that there were marked increases in Methylophilus. Methylophilus might be associated with favourable preservation in these anaerobic conditions. More research is needed to clearly link the presence of Methylophilus with vivianite production. The study emphasises the need for further integration of chemical and microbiome approaches, especially in good preservation areas, to explore microbial and chemical degradation mechanisms

    Association football and the representation of homosexuality by the print media: a case study of Anton Hysén

    Get PDF
    In March 2011 Anton Hysén (a semi-professional footballer currently playing in the Swedish fourth division) became only the second association football (soccer) player of any professional disposition to publicly declare his homosexuality whilst still playing the game. This article provides a textual analysis of the print media’s reaction to Hysén coming out and examines whether, in 2011, they portray more inclusive notions towards homosexuality than they did in 1990 when British footballer Justin Fashanu came out. The results advance inclusive masculinity theory as a number of print media sources (mostly British) interview Hysén in the weeks immediately after he came out and publish articles that challenge homophobia. Highlighting a change since 1990, a significant number of articles stress the need for the key stakeholders in football (players, fans, clubs, agents, the authorities and the media) to accept gay players

    Genomic erosion in the assessment of species extinction risk and recovery potential

    Get PDF
    Many species are facing unprecedented population size declines and deterioration of their environment. This exposes species to genomic erosion, which we define here as the damage inflicted to a species’ genome or gene pool due to a loss of genetic diversity, an increase in expressed genetic load, maladaptation, and/or genetic introgression. The International Union for Conservation of Nature (IUCN) bases its extinction risk assessments on direct threats to population size and habitat. However, it does not assess the long-term impacts of genomic erosion, and hence, it is likely to underestimate the extinction risk of many species. High-quality whole genome sequence data that is currently being generated could help improve extinction risk assessments. Genomic data contains information about a species’ past demography, its genome-wide genetic diversity, the incidence of genetic introgression, as well as the genetic load of deleterious mutations. Computer modelling of these data enables forecasting of population trajectories under different management scenarios. In this Perspective, we discuss the threats posed by genomic erosion. Using evolutionary genomic simulations, we argue that whole genome sequence data provides critical information for assessing the extinction risk and recovery potential of species. Genomics-informed assessments of the extinction risk complement the IUCN Red List, and such genomics-informed conservation is invaluable in guiding species recovery programs in the UN’s Decade on Ecosystem Restoration and beyond

    In-roads to the spread of antibiotic resistance: regional patterns of microbial transmission in northern coastal Ecuador

    Get PDF
    The evolution of antibiotic resistance (AR) increases treatment cost and probability of failure, threatening human health worldwide. The relative importance of individual antibiotic use, environmental transmission and rates of introduction of resistant bacteria in explaining community AR patterns is poorly understood. Evaluating their relative importance requires studying a region where they vary. The construction of a new road in a previously roadless area of northern coastal Ecuador provides a valuable natural experiment to study how changes in the social and natural environment affect the epidemiology of resistant Escherichia coli. We conducted seven bi-annual 15 day surveys of AR between 2003 and 2008 in 21 villages. Resistance to both ampicillin and sulphamethoxazole was the most frequently observed profile, based on antibiogram tests of seven antibiotics from 2210 samples. The prevalence of enteric bacteria with this resistance pair in the less remote communities was 80 per cent higher than in more remote communities (OR = 1.8 [1.3, 2.3]). This pattern could not be explained with data on individual antibiotic use. We used a transmission model to help explain this observed discrepancy. The model analysis suggests that both transmission and the rate of introduction of resistant bacteria into communities may contribute to the observed regional scale AR patterns, and that village-level antibiotic use rate determines which of these two factors predominate. While usually conceived as a main effect on individual risk, antibiotic use rate is revealed in this analysis as an effect modifier with regard to community-level risk of resistance

    "Aye, but it were wasted on thee": Cricket, British Asians, ethnic identities, and the 'magical recovery of community'

    Get PDF
    People in sport tend to possess rather jaded perceptions of its colour-blindness and thus, they are reluctant to confront the fact that, quite often racism is endemic. Yorkshire cricket in particular, has faced frequent accusations from minority ethnic communities of inveterate and institutionalised racism and territorial defensiveness. Drawing upon semi-structured interviews conducted with amateur white and British Asian cricketers, this paper examines the construction of regional identities in Yorkshire at a time when traditional myths and invented traditions of Yorkshire and 'Yorkshireness' are being deconstructed. This is conceptualised through a reading of John Clarke's 'magical recovery of community'. Although cricket has been multiracial for decades, I argue that some people's position as insiders is more straightforward than others. I present evidence to suggest that, regardless of being committed to Yorkshire and their 'Yorkshireness', white Yorkshire people may never fully accept British Asians as 'one of us'. Ideologically and practically, white Yorkshire people are engaged in constructing British Asians as anathema to Yorkshire culture. The paper concludes by advocating that, for sports cultures to be truly egalitarian, the ideology of sport itself has to change. True equality will only ever be achieved within a deracialised discourse that not only accepts difference, but embraces it

    Life After Succession in the Family Business: Is It Really the End of Problems?

    Get PDF
    The succession processes in family business are well chronicled in the business literature. Most of the research focuses on the process of transferring power within the business-family. What has not been as closely examined is the after-succession environment that exists when the management and leadership of the family business are passed on to the next generation. This article addresses that organizational climate and the potential for additional problems in the business-family if post-succession issues are not identified and addressed and suggests some steps that will be helpful in producing complete succession success.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
