AbstractThis manuscript presents an empirically tested model of entrepreneurial intentions based upon social cognitive career theory (SCCT). Our study consisted of 320 undergraduate business students at a large U.S. university and emphasizes the important influences of prior exposure to entrepreneurship, as well as social support mechanisms on formation of entrepreneurial intentions and entrepreneurial outcome expectations. We offer strong theoretical support to the entrepreneurial intentions literature through the lens of SCCT. Additionally, our manuscript highlights the important role of entrepreneurial attitude in mediating the relationship between entrepreneurial motivation and intention. SCCT offers additional explanation to the existing underspecified model and complexity of entrepreneurial intentions. In this manuscript the authors identify attitude as an important precursor to entrepreneurial intent.

AbstractDietary analyses were carried out on four species of native birds on Tiritiri Matangi and Motuora Islands, New Zealand, between February 2007 and February 2008. We examined regurgitated pellets of kingfishers, moreporks and swamp harriers, and the faeces of pukeko. Remains of lizards were found in 88% and 43% of regurgitated kingfisher pellets on Tiritiri Matangi and Motuora, respectively. All remains belonged to one species, Oligosoma moco. No evidence of lizard predation was found for the other three bird species. Translocation of lizards to areas supporting a high abundance of kingfishers should take avian predation risk into account.

A thin gash in the continental slope northwest of Monterey Bay, Ascension Canyon, is steep, with sides and axis both strongly supercritical to M2internal tides. A hydrostatic model forced with eight tidal constituents shows no major sources feeding energy into the canyon, but significant energy is exchanged between barotropic and baroclinic flows along the tops of the sides, where slopes are critical. Average turbulent dissipation rates observed near spring tide during April are half as large as a two week average measured during August in Monterey Canyon. Owing to Ascension's weaker stratification, however, its average diapycnal diffusivity, 3.9 × 10−3m2s−1, exceeded the 2.5 × 10−3m2s−1found in Monterey. Most of the dissipation occurred near the bottom, apparently associated with an internal bore, and just below the rim, where sustained cross‐canyon flow may have been generating lee waves or rotors. The near‐bottom mixing decreased sharply around Ascension's one bend, as did vertically integrated baroclinic energy fluxes. Dissipation had a minor effect on energetics, which were controlled by flux divergences and convergences and temporal changes in energy density. In Ascension, the observed dissipation rate near spring tide was 2.1 times that predicted from a simulation using eight tidal constituents averaged over a fortnightly period. The same observation was 1.5 times the average of an M2‐only prediction. In Monterey, the previous observed average was 4.9 times the average of an M2‐only prediction. As hypothesized, mixing in Ascension is less than in Monterey CanyonA hydrostatic model shows no major sources feeding energy into Ascension CanyonLee waves, rotors from cross flow, and internal tide beams may cause the mixing
