Opportunity recognition attitudes of nascent indigenous entrepreneurs

This exploratory research aims to fill a gap in the literature. The current theory of entrepreneurial attitude toward opportunity recognition (EOR) is primarily based upon a non-indigenous entrepreneurship theory. Yet, there are significant differences between non-indigenous and indigenous forms of entrepreneurship. Non-indigenous entrepreneurship tends to emphasise economic objectives whereas indigenous entrepreneurship tends to embrace both economic and non-economic objectives. As such, the current EOR theory needs to be expanded to include both non-indigenous and indigenous similarities and differences. This research uses indigenous culture as a context for examining the relationships between personal values, EOR and expected personal success of nascent indigenous entrepreneurs.

Pervasive limitations : innovating with ambient intelligence (AmI) technologies and restricted absorptive capacity in Australian SME manufacturers

The last 25 years have seen rapid increases in the number and sophistication of technological and process innovations in large manufacturers, producing dramatic improvements in productivity and efficiency. However, smaller manufacturers’ adoption of such innovations has been uneven. Ambient Intelligence (AmI) technologies are being positioned as the next performance and productivity enhancing purchase for manufacturers. This paper defines and gives examples of AmI technologies in current use, summarises AmI technologies of potential interest to small and medium enterprise (SME) manufacturers, and identifies potential impacts of restricted absorptive capacity in SMEs on the adoption of AmI technologies. Comparing two SME manufacturers, one from Germany and one from Australia illustrates a potential application of generic AmI technology based business solutions to a range of SME manufacturers.

Identification and expression of natriuretic peptide receptor Type-A and-B mRNA in freshwater and seawater rainbow trout

Natriuretic peptide receptors mediate the physiological response of  natriuretic peptide hormones. One of the natriuretic peptide receptor types is the particulate guanylyl cyclase receptors, of which there are two identified: NPR-A and NPR-B. In fishes, these have been sequenced and characterized in eels, medaka, and dogfish shark (NPR-B only). The euryhaline rainbow trout provides an opportunity to further pursue examination of the system in teleosts. In this study, partial rainbow trout NPR-A-like and NPR-B-like mRNA sequences were identified via PCR and cloning. The sequence information was used in real-time PCR to examine mRNA expression in a variety of tissues of freshwater rainbow trout and rainbow trout acclimated to 35 parts per thousand seawater for a period of 10 days. In the excretory kidney and posterior intestine, real-time PCR analysis showed greater expression of NPR-B in freshwater fish than in those adapted to seawater; otherwise, there was no difference in the expression of the individual receptors in fresh water or seawater. In general, the expression of the NPR-A and NPR-B type receptors was quite low. These findings indicate that NPR-A and NPR-B mRNA expression is minimally altered under the experimental regime used in this study.
