The role of materially heterogeneous entities in the entrepreneurial network

Few researchers have examined empirically the dynamics of human-non-human networking and its importance for strategic outcomes, particularly in the field of entrepreneurship. In this paper, we use Actor-Network Theory to observe and investigate the role of materially heterogeneous entities in the entrepreneurial network. Building on the results of a four-year, multi-case study, this paper describes how an entrepreneurial network, beyond its social nature, is also a socio-material constellation. The symmetric treatment of human and non-human actors enables us to move away from the figure of the heroic entrepreneur. Our findings reveal various roles that the heterogeneity of actor-networks can play in the entrepreneurial process. We see on the one hand their power to attract and recruit new allies when they are aligned with the entrepreneur's vision, and on the other their ability to repel and block the new venture creation process when they fail to effectively translate what the entrepreneur has in mind

Slack resources, exploratory and exploitative innovation and the performance of small technology-based firms

This paper aims to contribute (1) to the understanding about how small technology based firms in spite of being constrained by limited resources, can still perform exploratory and exploitative innovation and (2) to extend knowledge about the role of slack resources in the context of small technology-based firms in facilitating those innovation activities. Herein, we focus on two types of slack resources: internal slack, resources that are available within the firms and external slack, additional resources that are gathered through the facilitation of external sources such as business incubators. Using a sample of 141 small technology-based firms located at incubators, this study combined two streams of research on incubator studies and innovation to construct some hypotheses examining the role of slack resources and innovation activities in enhancing the performance of small technology-based firms operating in incubator setting. Our findings demonstrate that neither slack resources nor innovation activities alone explain firm performance. Instead, small technology-based firms fit their innovation activities to their slack resources. While the relationship between internal slack and performance is mediated by exploitative innovation, exploratory innovation plays a role as a mediator for the relationship between external slack and performance

The impact of university-based incubation support on the innovation strategy of academic spin-offs

This paper develops understanding about how incubation support and innovation strategy can determine the performance of academic spin-offs. Using a sample of spin-offs from the United Kingdom, the Netherlands and Norway, we analyse the potential moderating effect of incubation support (networking and entrepreneurial support) on innovation strategy effectiveness. The empirical results demonstrate: (1) a technology and market exploitation strategy has a stronger and more positive effect on the performance of spin-offs than a technology and market exploration strategy. In relation to an ambidextrous technology and market exploration and exploitation strategy, a market growth strategy (combining technology exploitation and market exploration) has a positive effect on performance while a product development strategy (combining technology exploration and market exploitation) has little effect on performance; (2) incubation support in the form of networking and entrepreneurial support has a positive effect on the performance of spin-offs; (3) networking support moderates the relationship between an exploitation strategy and spin-off performance while entrepreneurial support moderates the relationship between a market growth strategy and spin-off performance. By examining the interactions between types of innovation strategies and incubation support, this study provides a more refined understanding of the strategy selected by spin-offs. In doing so, it offers new insights about the role of incubator support in enhancing the effect of strategy on performance

Dual, Photo‐Responsive and Redox‐Active Supramolecular Foldamers

We report on dual, light‐responsive and redox‐active foldamers that demonstrate reversible and robust stimuli‐induced behaviour. Herein, UV/Vis, 1H NMR and circular dichroism (CD) spectroscopy and cyclic voltammetry have been used to establish the reversibility and highly robust nature of the light‐ and redox‐driven behaviour of these new foldamers with minimal levels of fatigue observed even upon multiple cyclic treatments with irradiative/non‐irradiative and oxidative/reductive conditions. This proof‐of‐concept work paves the way towards the creation of novel stimuli‐responsive foldamers of increasing sophistication capable of demonstrating reversible and robust responses to multiple distinct stimuli

Entrepreneurial learning from observing role models

This study examines entrepreneurial learning through the observation of role models. Adopting an interpretive and inductive approach, and using biographical interviews and life course techniques, the article examines how sixteen entrepreneurs articulate their entrepreneurial learning from role models. The overarching research question ‘How do entrepreneurs learn from observing role models?’ enables illustrating who the role models are (parents, teachers, colleagues, other entrepreneurs), the relevant social contexts (home, education, workplace) and what is learned in relation to entrepreneurial learning tasks (learning about oneself, managing relationships, the business and small business management). The study contributes to developing the social perspectives of entrepreneurial learning by demonstrating the significance of learning from role models in different social contexts and at distinct entrepreneurial stages pre- and post-start-up

Re-framing the status of narrative in family business research:towards an understanding of families in business

This article will emphasize the status and relevance of narrative research in the study of families in business and family business strategy. It argues that narratives can provide a better understanding of the intricate connections between family and business and across family generations in business. Narratives generate knowledge by helping to shape a collective identity and as a form of intergenerational communication. By focusing on narratives as a phenomenological inquiry, we argue that interviews allow researchers to engage often in emotionally charged and intimate conversations with individuals that want to talk about experiences as members of a family business. This paper will discuss the usefulness of narrative approaches for family business strategy research, develop a catalogue of research questions for exploration, highlight challenges and offer solutions to deal with them when using narrative methods in family business research. This paper argues that while several challenges may be encountered, narratives allow researchers to delve into the intricate lives of members of a family in business

A step into the unknown:universities and the governance of regional economic development

As the social and economic landscape changes, universities are coming under growing pressure to contribute to the economic development of their localities. This paper explores the increasing trends towards universities as key actors in the governance of regional economic development through activities to support economic and entrepreneurship development in their regions. A case study is presented of an institution in the UK which is increasingly situating itself in the economic governance sphere. Drawing on the experiences of those working at the coalface of economic governance activities, the opportunities and potential challenges faced by a university when engaging in such activities are explored. The ultimate goal of this paper is to shed light on universities’ activities in the realm of regional economic governance, an area currently under-explored in extant literature

Plasma evolution within an erupting coronal cavity

Coronal cavities have previously been observed associated with long-lived quiescent filaments and are thought to correspond to the associated magnetic flux rope. Although the standard flare model predicts a coronal cavity corresponding to the erupting flux rope, these have only been observed using broadband imaging data, restricting analysis to the plane-of-sky. We present a unique set of spectroscopic observations of an active region filament seen erupting at the solar limb in the extreme ultraviolet (EUV). The cavity erupted and expanded rapidly, with the change in rise phase contemporaneous with an increase in non-thermal electron energy flux of the associated flare. Hot and cool filamentary material was observed to rise with the erupting flux rope, disappearing suddenly as the cavity appeared. Although strongly blue-shifted plasma continued to be observed flowing from the apex of the erupting flux rope, this outflow soon ceased. These results indicate that the sudden injection of energy from the flare beneath forced the rapid eruption and expansion of the flux rope, driving strong plasma flows which resulted in the eruption of an under-dense filamentary flux rope.Comment: 11 pages, 5 figures.

Breast Cancer Risk in Young Women in the National Breast Screening Programme: Implications for Applying NICE Guidelines for Additional Screening and Chemoprevention

In the United Kingdom, women at moderate and high risk of breast cancer between the ages of 40 and 49 years are eligible for annual mammographic screening and preventive therapy with tamoxifen. Here, we estimate the numbers of women in a population eligible for this service and the proportion of breast cancers detected in this group compared with the whole population. Wome
