Variable risk preferences in new firm growth and survival

We outline and test a decision-making theory of new venture growth and survival. Building upon research in entrepreneurship and decision making under risk, we hypothesize that entrepreneurs' attention to survival and aspiration reference points changes based on venture age (experience-based learning), size (differences in decision complexity), and performance decision domain. Examining a panel of 14,760 new ventures in the professional services sector, our findings show how risk preferences change as a venture ages and increases in size. This approach offers a more nuanced view of decision making under risk and provides a theoretical explanation for the common patterns of new ventures' probability of exit and growth diminishing with age and size

Selected ion flow tube cation-molecule reaction studies and threshold photoelectron photoion coincidence spectroscopy of cyclic C5F8

Using tunable vacuum-UV radiation from a synchrotron, the threshold photoelectron and threshold photoelectron photoion coincidence spectra of cyclic-C$_4$F$_8$ in the range 11–25 eV have been recorded. The parent ion is observed very weakly at threshold, 11.60 eV, and is most likely to have cyclic geometry. Ion yield curves and branching ratios have been determined for five fragments. Above threshold, the first ion observed is C$_3$F$_5^+$, at slightly higher energy C$_2$F$_4^+$, then successively CF$_3^+$, CF$_2^+$ and CF$^+$ are formed. The dominant ions are C$_3$F$_5^+$ and C$_2$F$_4^+$, with the data suggesting the presence of a barrier in the exit channel to production of C$_3$F$_5^+$ whilst no barrier to production of C$_2$F$_4^+$. In complementary experiments, the product branching ratios and rate coefficients have been measured in a selected ion flow tube at 298 K for the bimolecular reactions of cyclic-C$_4$F$_8$ with a large number of atomic and small molecular cations. Below the energy where charge transfer becomes energetically allowed, only one of the ions, CF$_2^+$, reacts. Above this energy, all but one of the remaining ions reacts. Experimental rate coefficients are consistently greater than the collisional values calculated from modified average dipole orientation theory. The inclusion of an additional ion-quadrupole interaction has allowed better agreement to be achieved. With the exception of N$^+$, a comparison of the fragment ion branching ratios from the TPEPICO and SIFT data suggest that long-range charge transfer is the dominate mechanism for reactions of ions with recombination energy between 12.9 and 15.8 eV. For all other ions, either short-range charge transfer or a chemical reaction, involving cleavage and making of new bond(s), is the dominant mechanism

A neuroethics framework for the Australian Brain Initiative

Neuroethics is central to the Australian Brain Initiative’s aim to sustain a thriving and responsible neurotechnology industry. Diverse and inclusive community and stakeholder engagement and a trans-disciplinary approach to neuroethics will be key to the success of the Australian Brain Initiative
