Innovative entrepreneurial entry over the business cycle: variation by form of innovation and country economic development

Paul Steffens, Kim Klyver

Abstract While prior studies indicate innovation and product introductions decrease during economic downturns and recessions, the nature of innovative entry by startups is unclear. Furthermore, studies of business entry, which is dominated by non-innovative firms, show mixed results. We build on innovation …

Reimagining entrepreneurial ecosystems for sustainable development

Iulia Stroila, Paul Steffens, Carolin Plewa

Entrepreneurial ecosystems are widely recognized for fostering innovation, job creation, and economic growth. However, increasing attention is being paid to the negative externalities they may produce, including environmental degradation, social inequality, and reduced well-being. In response, the concept of sustainable entrepreneurial ecosystems …

Incipient modulated phase in Sr$_{1-x}$Ca$_{x}$TiO$_3$

Benoît Fauqué, D. A. Chaney, P. Bourges, S. Raymond et autres

Nanometer-scale modulations can spontaneously emerge in complex materials when multiple degrees of freedom interact. Here we demonstrate that ferroelectric Sr$_{1-x}$Ca$_x$TiO$_3$ lies in close proximity to an incipient structurally modulated phase. Using inelastic neutron and X-ray scattering, we show that upon cooling, dipolar …

Crisis perceptions among Ukrainian refugee entrepreneurs: Psychological antecedents and venture progress

Kim Klyver, Paul Steffens

Refugees face challenging circumstances. We contend that facing extreme adversity, in addition to the uncertainty always associated with entrepreneurship, renders entrepreneurship particularly challenging. We propose that heightening perceptions of opportunities and dampening perceptions of constraints are critical for refugees to engage in …

Latent Class Markov Modeling for Studying Dynamic Organizational Configurations

Paul Steffens, Leonard J. Paas, Scott R. Gordon

Interest in configurational approaches has seen a resurgence in organizational studies. Techniques such as QCA and fsQCA, commonly used to analyze organizational configurations, are static in nature and temporal extensions are limited. However, organizational researchers are often concerned with changes in organizational …

Gapped commensurate antiferromagnetic response in a strongly underdoped model cuprate superconductor

Zachary Anderson, Yang Tang, Vikram Nagarajan, M. K. Chan et autres

It is a distinct possibility that spin fluctuations are the pairing interactions in a wide range of unconventional superconductors. In the case of the high-transition-temperature (high-$T_c$) cuprates, in which superconductivity emerges upon doping an antiferromagnetic Mott-insulating state, spin correlations might furthermore drive …

Spin excitations arising from anisotropic Dirac spinons in YCu$_3$(OD)$_6$Br$_2$[Br$_{0.33}$(OD)$_{0.67}$]

Lankun Han, Zhenyuan Zeng, Bo Liu, Maiko Kofu et autres

A Dirac quantum spin liquid hosts Dirac spinons, which are low-energy fractionalized neutral quasiparticles with spin 1/2 that obey the Dirac equation. Recent inelastic neutron scattering studies have revealed a cone spin continuum in YCu$_3$(OD)$_6$Br$_2$[Br$_{x}$(OD)$_{1-x}$], consistent with the convolution of two Dirac …

What Actions are Helpful for Marginalized Entrepreneurs? Developing Questions Inductively

Alexander Glösenberg, Paul Steffens, Michael Fresé, Manjula Dissanayake et autres

It has been proposed that entrepreneurs with few socioeconomic resources engage in different entrepreneurial processes than more privileged entrepreneurs. However, it remains unclear what actions socioeconomically marginalized entrepreneurs might need to adopt to obtain successful outcomes. Increasingly, it is believed that individual …

Opportunity Attitude: Moving Beyond Cognitive-Centric Evaluation of Entrepreneurial Opportunities

Binyam Zewde Alemayehu, Paul Steffens, Scott R. Gordon

Opportunity evaluation is an important concept in entrepreneurship, central to our understanding of how individuals evaluate specific opportunities, develop entrepreneurial intentions and (possibly) engage in entrepreneurial behavior. Existing understandings of opportunity evaluation tend to adopt a cognitive-centric approach. We build on the …
