Common genetic effects on risk-taking preferences and choices

Although prior research has shown that risk-taking preferences and choices are correlated across many domains, there is a dearth of research investigating whether these correlations are primarily the result of genetic or environmental factors. We examine the extent to which common genetic factors account for the association between general risk-taking preferences and domain specific risk-taking preferences, and between general risk-taking preferences and risk taking choices in financial investments, stock market participation and business formation. Using data from 1898 monozygotic (MZ) and 1344 same-sex dizygotic (DZ) twins, we find that general risk-taking shares a common genetic component with domain-specific risk-taking preferences and risk-taking choices

Management of construction jobsite productivity : a self assessment approach

A critical component of construction project management is the improvement of jobsite productivity. This paper proposes a procedure for use by project managers to assess jobsite productivity performance. The methodology provides a framework which when applied will identify specific aspects of the jobsite where potential productivity improvement is possible. A major feature is its systematic approach which will direct the project manager to the specific resources which when better managed will lead to lower construction costs

Resource orchestration in startups : synchronizing human capital investment, leveraging strategy and founder startup experience

Research Summary: We examine the performance effects of resource orchestration in start-ups by investigating three key contingencies of resource orchestration: human capital (HC) investment relative to rivals, leveraging strategy, and founder start-up experience. We find that deviating from rivals' resource investments (either above or below the industry mean) negatively affects performance, while conforming to the norms set by rivals positively affects performance. However, we also find that a higher investment in HC relative to rivals is less detrimental when aligned with a leveraging strategy focused on innovation. In addition, we find evidence that this relationship is conditioned by the entrepreneurial experience of the founders themselves. Managerial Summary: To create value, entrepreneurs need to assemble and manage various resources and capabilities. We explain how entrepreneurs can manage their resources to achieve higher performance. Using a sample of U.S. start-ups, we find that deviations in human capital (HC) investments relative to rivals (either below or above) harm the performance of start-ups. However, we also find that a higher investment in HC relative to rivals is less detrimental when the start-up is focused on innovation. In addition, we find that experienced founders benefit from actively orchestrating HC investments relative to rivals with a strategy focused on innovation

Electronic performance monitoring : the crossover between self-discipline and emotion management

This thesis studies the crossover between self-discipline and emotion management in an electronic performance monitoring (EPM) setting. The intersection between these two elements is explained in terms of six main themes: control, power and discipline; compliance, conformity and resistance; rationality, performance standards and corrective action; emotional labour and the management of emotions; society, responsibility and accountability; and subjectivity, internalisation and the self. These main themes emerged from interview data and are supported by the literature. A qualitative methodology was adopted to support a social constructionist perspective. Semi-structured interviews were conducted to collect data from a single case study organisation, and thematic coding was used for analysis. EPM systems installed in the case study call centre are used to control agents’ behaviour, embedding in their minds the importance of controlling and disciplining their own behaviour. They are forced by EPM to manage their own emotions and conform to the rules of the system through self-discipline. Nevertheless, some find it difficult constantly to suppress their emotions and may exhibit resistance. There is a preoccupation with self-correction. Agents internalise the call centre's norms of behavior. The technological environment largely determines the way in which they manage their emotions. They fake their emotions when interacting with callers, supervisors and colleagues, and exercise self-discipline and emotion management to satisfy personal and group expectations. They incorporate the cultural values, motives and beliefs of the EPM context through learning, socialisation and identification. This thesis offers significant theoretical contributions which revolve around the relationship between surveillance-induced self-discipline and emotional labour over time. It aims to alert academics and business people to the problems of emotional labour and to prompt them to make changes to the design, implementation and use of EPM

The biological perspective in entrepreneurship research

The past decade has experienced a significant increase in the number of papers on the biology of entrepreneurship. This trend is aligned with the general interest in the biology of management studies as evidenced by the more than 300 articles already published (Nofal et al., 2018). It illustrates the progression of science along two dimensions. First is the drive to seek smaller units of analyses to identify the core mechanisms of action. Second is the opposing drive to seek larger units of analyses to identify general principles. These simultaneous processes move our understanding of social and natural phenomena closer to a unified theory. In this note, we reflect on how the biology of why, how, what, when, and where of entrepreneurship represents a natural progression from the institutional, organizational, and psychological explanations. We call this the biological perspective in entrepreneurship (BPE), which is illustrated by the papers in this volume. We examine the key domains of inquiry, various methodologies, and reflect on the directions that future research should take

Chapter 5 The Biology of Entrepreneurship

In this chapter, we provide a systematic review of the biological perspective in entrepreneurship. Specifically, we systematically review research linking the three biological strands of genetics, physiology, and neuroscience to entrepreneurship. We discuss the findings of this growing literature and how incorporating biology into the study of entrepreneurship can enhance our understanding of various entrepreneurial outcomes. We then discuss the mechanisms through which biology affects entrepreneurship. Finally, we conclude with directions for future research

Exploring the potential and limits of a neuroscientific approach to entrepreneurship

We critically examine the potential that neuroscience holds for the future of entrepreneurship research and provide a framework for entrepreneurship researchers interested in pursuing this line of inquiry. Specifically, we propose four complementary mechanisms through which neuroscience can inform entrepreneurship theory and research. We conclude with a discussion of the limitations and ethical implications of a neuroscientific approach to entrepreneurship

Testosterone and the tendency to engage in self-employment

Does testosterone increase the tendency to engage in self-employment? The results presented to date have been mixed. Using three different studies, we provide additional evidence on the relationship between testosterone and self-employment. Drawing on a cross-section of 2,146 individuals (1,178 males and 968 females) from the National Health and Nutrition Examination Surveys’ (NHANES’) 2011-2012 sample, and controlling for endogeneity (with red blood cell count, percentage Hematocrit, and zinc supplements intake in the past 30-days as instruments), serum testosterone levels are positively associated with self-employment for males (marginally significant, two-tailed test). As testosterone levels could be affected by social, economic, and biological factors during one’s life course, to draw more robust inferences we assess whether the 2D:4D digit ratio, a marker of prenatal testosterone exposure, influences the likelihood of self-employment. We reviewed a sample of 971 cases (449 males and 525 females) from Understanding Society’s Innovation Panel 6 (IP6), and our results indicate that males (females) with lower 2D:4D ratio in their left hand, or higher prenatal testosterone exposure, have a significantly greater (marginally significant for females) likelihood of self-employment (two-tailed test). Finally, we examine the twin testosterone transfer effect in a sample of opposite-sex and same-sex twins from the National Survey of Midlife Development (MIDUS I) in the Unites States and provide additional support for the marginally significant (two-tailed test) positive association between testosterone and self-employment

Exploring the sentiment of entrepreneurs on Twitter

Sentiment analysis is an evolving field of study that employs artificial intelligence techniques to identify the emotions and opinions expressed in a given text. Applying sentiment analysis to study the billions of messages that circulate in popular online social media platforms has raised numerous opportunities for exploring the emotional expressions of their users. In this paper we combine sentiment analysis with natural language processing and topic analysis techniques and conduct two different studies to examine whether engagement in entrepreneurship is associated with more positive emotions expressed on Twitter. In study 1, we investigate three samples with 6.717.308, 13.253.244, and 62.067.509 tweets respectively. We find that entrepreneurs express more positive emotions than non-entrepreneurs for most topics. We also find that social entrepreneurs express more positive emotions, and that serial entrepreneurs express less positive emotions than other entrepreneurs. In study 2, we use 21.491.962 tweets to explore 37.225 job-status changes by individuals who entered or quit entrepreneurship. We find that a job change to entrepreneurship is associated with a shift in the expression of emotions to more positive ones

Temporal changes in the prevalence of childhood asthma and allergies in urban and rural areas of Cyprus: results from two cross sectional studies

<p>Abstract</p> <p>Background</p> <p>The prevalence of childhood asthma and allergies in Cyprus was significantly higher in urban compared to rural areas back in the year 2000, against a background of an overall low prevalence (e.g. current wheeze 6.9%) by comparison to northern European countries. In this study we aimed to assess temporal changes in the prevalence of asthma and allergies in Cyprus after an 8-year interval and to examine whether any differential changes have occurred in urban and rural parts of the island.</p> <p>Methods</p> <p>During the academic years 1999-2000 and 2007-2008, the parents of 7-8 year old children residing in the same set of urban and rural areas completed the ISAAC core questionnaire. In addition to providing prevalence estimates of allergic diseases in 2000 and 2008, changes between the two periods were expressed as odds ratios estimated in multiple logistic regression models adjusting for survey participants' characteristics.</p> <p>Results</p> <p>The prevalence of current wheeze was higher in 2008 (8.7%, 95% confidence interval 7.5%-9.9%, n = 2216) than the previously recorded figure in 2000 (6.9%, 95% CI 6.2%-7.6%, OR = 1.25, 95% CI: 1.02-1.53, n = 4944). Significant increases were also seen in the prevalence of lifetime asthma (11.3% vs. 17.4%, OR = 1.59, CI: 1.36-1.86), eczema (6.8% vs. 13.5%, OR = 1.91, CI: 1.59-2.29) and allergic rhinoconjuctivitis (2.6% vs. 5.2%, OR = 1.82, CI: 1.39-2.41). The prevalence of current wheeze nearly doubled between 2000 and 2008 in rural areas (5.4% vs. 9.7%, OR 1.81, CI: 1.24-2.64) while no significant change was observed in urban areas (7.5% vs. 8.4%, OR 1.08, CI: 0.84-1.37); p value for effect modification = 0.04. Rises in asthma and rhinitis prevalence, but not eczema were also more pronounced in rural compared to urban areas.</p> <p>Conclusions</p> <p>The prevalence of allergic diseases in Cyprus is still on the rise; recent increases appear more pronounced among children living in rural areas possibly indicating recent environmental and lifestyle changes in these communities</p
