ARTICULATING THE INTUITIVE: MECHANISMS FOR ENTREPRENEURS TO COMMUNICATE OPPORTUNITY EVALUATION DECISION POLICIES
Thesis (PhD) - Indiana University, Business, 2006Ironically in the development of expertise, as expertise increases, an individual's ability to communicate the knowledge associated with that expertise decreases. This lack of transferability can be beneficial (the knowledge is inimitable by competitors), but it can also be detrimental (the knowledge is not usable by colleagues and other stakeholders). These differences likely arise from different types of causal ambiguity. Ambiguity about the attributes of a specific entrepreneurial opportunity represents a barrier to the transferability of knowledge to competitors (beneficial), while ambiguity about the relationship between a specific opportunity and value creation represents a barrier to the transferability of knowledge to stakeholders (detrimental). To reduce specific opportunity/value creation relationship ambiguity, I focus in this research on mechanisms thought to enhance entrepreneurial decision makers' decision-policy consciousness in opportunity evaluation decisions. In a field experiment, I capture the opportunity evaluation decisions of 127 entrepreneurial decision makers in high potential technology ventures, and introduce a series of experimental manipulations hypothesized to increase the decision-policy consciousness of these individuals. The findings suggest that firm founders have lower decision-policy consciousness than non-firm founders; that codification increases decision-policy consciousness; that in increasing decision-policy consciousness, codification is more efficacious for founders than non-founders; that opportunity desirability, feasibility and environment play a significant role in opportunity evaluation; and that as a result of specific individual cognitive factors, systematic differences exist across opportunity evaluation decision policies. In addition to the practical implications of these results for new venture founding, they also contribute to both the entrepreneurial cognition literature and the strategic capabilities literature

Occurrence of Two Species of Old World Bees, \u3ci\u3eAnthidium Manicatum\u3c/i\u3e and \u3ci\u3eA. Oblongatum\u3c/i\u3e (Apoidea: Megachilidae), in Northern Ohio and Southern Michigan
Anthidium manicatum and A. oblongatum are two European bees species that have recently established themselves in North America. Anthidium manicatum has previously been documented in New York and Ontario, Canada, and A. oblongatum has been documented in New York, New Jersey, Maryland, and eastern Pennsylvania. We surveyed a number of sites in Ohio, Michigan, and Indiana for these species in 2000 and 2001, and found both bee species to have extended their ranges into northern Ohio, and A. manicatum to have moved into southern Michigan. We present a key identifying the four Anthidium species now known from northeastern North America
Inter-correlations between laboratory Inter-correlations between laboratory and field-based tests of muscle contractile power
International Journal of Exercise Science 9(5): 635-645, 2016. Muscle contractile properties have previously been distinguished by fiber typing muscle samples obtained from needle biopsy; however due to conflicting evidence regarding sampling bias and the related need for multiple biopsies, it is not certain if these results are a reliable reflection of whole muscle fiber type expression. Inter-correlations between laboratory and field-based measures of muscle contractile power were used to determine which assessments best discriminate between participants of varying sprint performance, and indirectly reveal potential for power vs. endurance exercise performance. Healthy active male (n=32) and female (n=17) participants were recruited from the Central West region of New South Wales. Isometric rate of force development (RFD) and isokinetic torque were assessed at different velocities. A counter movement jump (CMJ) test was implemented to assess concentric and eccentric RFD. A modified Wingate test was used to assess peak power expressed as Watts using a stationary start to the onset of decreased cadence. A 20m sprint was used as a field-based measurement of exercise performance, recording split times at 2m, 10m and 20m, and interval times from 2-10m, 2-20m, and 10-20m. Over 85% (r2=0.851) of 10-20m sprint running performance variance was significantly accounted for by a multiple regression model consisting of peak Watts per kilogram body mass during the modified Wingate (pkWkg), sex, and peak concentric rate of force development (pkcRFDkg). Results indicate a highly significant and predictive relationship between performance measures assessed by the modified Wingate test and sprint running performance in both males and females. Laboratory power tests alone seem sensitive enough to ascertain suitability for power vs. endurance performance potential
Planar Airy beam light-sheet for two-photon microscopy
We demonstrate the first planar Airy light-sheet microscope. Fluorescence
light-sheet microscopy has become the method of choice to study large
biological samples with cellular or sub-cellular resolution. The
propagation-invariant Airy beam enables a ten-fold increase in field-of-view
with single-photon excitation; however, the characteristic asymmetry of the
light-sheet limits its potential for multi-photon excitation. Here we show how
a planar light-sheet can be formed from the curved propagation-invariant Airy
beam. The resulting symmetric light sheet excites two-photon fluorescence
uniformly across an extended field-of-view without the need for deconvolution.
We demonstrate the method for rapid two-photon imaging of large volumes of
neuronal tissue.Comment: 7 pages, 4 figure
