This work, which extends Squire et al. [ApJL, 830 L25 (2016)], explores the effect of self-generated pressure anisotropy on linearly polarized shear-Alfvén fluctuations in low-collisionality plasmas. Such anisotropies lead to stringent limits on the amplitude of magnetic perturbations in high-β plasmas, above which a fluctuation can destabilize itself through the parallel firehose instability. ...

We study the effects of diverse team composition on the survival and growth of new ventures using the Danish Linked Employer-Employee database. To get cleaner measures of diverse team composition, we focus on entrepreneurial dyads, and also investigate the asymmetric effects of team composition by distinguishing between the ‘primary’ and the ‘secondary’ founder. We complement existing work by s...

Using arguments from the behavioral theory of firm, agency theory, and literature on internal capital markets, this article investigates relationship between financial slack firms’ profitability in standalone versus business group–affiliated firms. a large sample French privately held firms, we show that there is quadratic, inverse U-shape for We observe relation steeper group affiliated firms ...

This study investigates how the Psychological Capital (PsyCap) of small and medium enterprises (SME) leaders has influenced their strategic responses, ultimately impacting performance companies, during COVID-19 pandemic. Embedded within research on behavioral micro-foundations in strategy, based resource-based theory (RBT) individual entrepreneur as well positive organizational behavior literat...

In this paper, we explore the optimal combination of femtosecond laser drilling parameters for micro-hole processing on DD6 single-crystal high-temperature alloy and analyze significance parameter variations microstructure characteristics holes. The L25(56) orthogonal test was performed by controlling six during ring processing: average power; overlap rate; defocus feed amount; gas pressure; en...

Article history: Received 20 October 2011 Received in revised form 11 July 2012 Accepted 12 July 2012 Available online 20 July 2012 In this paper we analyze the relationship between survival, employment growth and firm size in Chile, an economy that has reduced largely its trade barriers in the last three decades. We are particularly interested in analyzing whether the small and medium sized en...

As emphasized by Hausmann, Rodrik and Velasco, the policy challenge of boosting growth requires prioritization and identifying what are the most binding constraints. This paper draws on firm-level data from the World Bank Enterprise Survey, which suggests that the obstacles for the functioning of firms is related to firm size. Recognizing the potential endogeneity and simultaneity between firms...

This paper uses flight-level data and measures of Internet penetration in U.S. metropolitan statistical areas between 1997 and 2007 to study the relationship between Internet access and flight on-time performance, which represents a measure of flight quality. We find that on-time performance is substantially worse for flights in which passengers originated in areas with greater Internet access....
