Can Entrepreneurship Be Taught? AgEcon
Klein, Peter G.; Bullock, J. Bruce.
Is entrepreneurship an innate ability or an acquired skill? Can entrepreneurship acumen be achieved and enhanced through education and training, or are certain people “born” to be entrepreneurs or to act entrepreneurially? Economists and management theorists give widely divergent answers to these questions. This paper reviews the major approaches to teaching entrepreneurship, primarily at the undergraduate level, and relates them to economic theories of entrepreneurship. Surprisingly, we find little connection between the leading approaches to entrepreneurship education and economists’ understanding of the entrepreneurial function. We assess likely explanations for the lack of contact between these two groups of scholars and suggest possible...

Relative contribution of expectancy and immediate arousal to the facilitatory effect of an auditory accessory stimulus BJMBR
Del-Fava,F.; Ribeiro-do-Valle,L.E..
An auditory stimulus speeds up a digital response to a subsequent visual stimulus. This facilitatory effect has been related to the expectancy and the immediate arousal that would be caused by the accessory stimulus. The present study examined the relative contribution of these two influences. In a first and a third experiment a simple reaction time task was used. In a second and fourth experiment a go/no-go reaction time task was used. In each of these experiments, the accessory stimulus preceded the target stimulus by 200 ms for one group of male and female volunteers (G Fix). For another group of similar volunteers (G Var) the accessory stimulus preceded the target stimulus by 200 ms in 25% of the trials, by 1000 ms in 25% of the trials and was not...

Sentinels in Saltator atricollis (Passeriformes: Emberizidae) BJB
RAGUSA-NETTO,J..
I studied the existence of sentinels in Saltator atricollis in a 'campo-cerrado' (Brazilian savanna) during the breeding seasons of 1994-95 and 1995-96. Groups of this species consisted of two to seven birds (N = 25). Sentinels were present (mean ± sd) 62% ± 9% of the time, and most sentinel bouts lasted from less than one to six minutes (although in some occasions for more than 30 min.). Overlap of two or more sentinels occurred on average only 3.2% of the time with birds on guard. Sentinels commonly gave contact calls in the beginning and/or at the end of a sentinel bout. The group size had no effect on time with sentinels. However the encounter rate between raptors and groups significantly influenced the time guarded. The results of this study suggests...
