Pathways of Fire: An Empirical Look at Entrepreneurial Passion

This paper develops and tests a theory of entrepreneurial passion. We draw from the literature on identity theory to investigate the influence of entrepreneurial identities on entrepreneurial passion, as well as the relationship of entrepreneurial passion to behavior. Empirical analyses of responses from 247 entrepreneurs confirm that entrepreneurial passion rises and falls in connection with entrepreneurial identity centrality. Moreover, entrepreneurial passion influences entrepreneurial behavior through multiple pathways involving intrinsic motivation, self-efficacy and positive affect. This research provides new insights into the factors that impact entrepreneurial passion as well as the mechanisms through which that passion stokes the fire of entrepreneurial action

Entrepreneurial Passion: Sources and Sustenance

Entrepreneurial passion helps coordinate cognition and behavior of entrepreneurs, providing the fire that fuels innovation, persistence, and ultimate success. But where does entrepreneurial passion come from? Using a phenomenological approach, we conduct a qualitative study of 80 entrepreneurs and analyze their oral histories to explore the sources of entrepreneurial passion, as experienced by entrepreneurs. Our discovery process in the interviews suggests six major sources of entrepreneurial passion: passion for building/developing the venture, passion for people, passion for the product or service, passion for inventing, passion for competition, and passion for a social cause

Investigation of quantitative measures related to reading disability in a large sample of sib-pairs from the UK

We describe a family-based sample of individuals with reading disability collected as part of a quantitative trait loci (QTL) mapping study. Eighty-nine nuclear families (135 independent sib-pairs) were identified through a single proband using a traditional discrepancy score of predicted/actual reading ability and a known family history. Eight correlated psychometric measures were administered to each sibling, including single word reading, spelling, similarities, matrices, spoonerisms, nonword and irregular word reading, and a pseudohomophone test. Summary statistics for each measure showed a reduced mean for the probands compared to the co-sibs, which in turn was lower than that of the population. This partial co-sib regression back to the mean indicates that the measures are influenced by familial factors and therefore, may be suitable for a mapping study. The variance of each of the measures remained largely unaffected, which is reassuring for the application of a QTL approach. Multivariate genetic analysis carried out to explore the relationship between the measures identified a common factor between the reading measures that accounted for 54% of the variance. Finally the familiality estimates (range 0.32–0.73) obtained for the reading measures including the common factor (0.68) supported their heritability. These findings demonstrate the viability of this sample for QTL mapping, and will assist in the interpretation of any subsequent linkage findings in an ongoing genome scan

Study of the processing and properties of mixtures of recycled plastics for outdoor applications

There is an industrial need for the study of the mechanical and physical properties of recycled polyolefins mixed with cellulose fibres from diapers, wood and packaging containing aluminium. The recycling of thermoplastic based residues is economically very interesting for the easy reprocessing of these materials and flexible shaping using conventional moulding processes as injection moulding or intrusion. Various mixtures of these materials were characterized in terms of their constituents and properties determined using 200 mm square mouldings of 10 mm and 5 mm thickness, in view of their potential application in urban furniture. These mouldings were processed by injection moulding and by intrusion that is a method which uses and extruder for delivering the melt directly into an injection mould. The mouldings were tested in terms of theirmechanical performance in impact and flexion. The intrusion process yielded mouldings with properties similar to injection moulding but appeared to be more attractive for requiring lower moulding pressure and thus lighter and cheaper tooling. The morphology of the mouldings, observed by bright field light microscopy showed some contamination and voiding associated to specific processing conditions and moulding size, the thinner mouldings having less voids than the 10 mm thick. The higher voiding in the thicker mouldings was detrimental to the flexural and impact performances of the parts. The coefficient of linear thermal expansion was determined and showed to be sensitive to the percentage of LDPE and fibres in the mixtures. The flexural stiffness of the moulded plates was assessed using the whole mouldings in the 3-point support test and showed the positive influence of the wood fibres and the diaper content in the mixtures. Conversely the impact performance assessed by the Charpy test was affected by the diaper content, but benefitted from the presence of aluminium from the recycled packaging. The prediction of these properties using the law of mixtures for predicting the overall density in the mouldings was not particularly accurate for the mixtures with recycled diapers.European Commission for Education and Training, Erasmus placement scholarship at Hogeschool Gen
