Toward a Dynamic Learning Perspective of Entrepreneurship

ENTREPRENEURSHIP THEORY AND PRACTICE, Issue 4 2005
Jason Cope
This conceptual article introduces a dynamic learning perspective of entrepreneurship that builds upon existing "dominant" theoretical approaches to understanding entrepreneurial activity. As many aspects of entrepreneurial learning remain poorly understood, this article maps out and extends current boundaries of thinking regarding how entrepreneurs learn. It presents key conclusions from emergent empirical and conceptual work on the subject and synthesizes a broad range of contributory adult, management, and individual learning literature to develop a robust and integrated thematic conceptualization of entrepreneurial learning. Three distinctive, interrelated elements of entrepreneurial learning are proposed,dynamic temporal phases, interrelated processes, and overarching characteristics. The article concludes by demonstrating how a "learning lens" can be applied to create further avenues for research in entrepreneurship from a learning perspective. [source]

The extraction of power from a hot stream

INTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 6 2001
A. Bejan
Abstract The solution to the problem of maximizing the extraction of exergy from a stream of hot gas showed that the hot stream must be cooled in a counterflow heat exchanger with optimal imbalance of capacity rates, i.e. with an optimal capacity rate on the cold side. This paper outlines the first few steps toward making this solution practical, by combining the optimized counterflow with conventional components for compressing and expanding the cold stream. In the first part of the paper, the cold stream is compressed in an isothermal compressor, expanded in an adiabatic turbine, and discharged into the ambient. In the second part, the cold stream is compressed in an adiabatic compressor. Both designs are optimized with respect to two degrees of freedom, the capacity-rate imbalance of the counterflow, and the pressure ratio maintained by the compressor. The effect of other constraints is documented, e.g. heat transfer area size, hot gas initial temperature and compressor and turbine efficiencies. This study shows the tradeoff between simplicity and increased performance, and outlines the path for further conceptual work on the extraction of exergy from a hot stream that is being cooled gradually.

Is Justice Binary?: A Free-Will-Related Exploration

METAPHILOSOPHY, Issue 4 2003
Saul Smilansky
Abstract: This article asks whether justice is binary, whether matters are either-or with respect to it. This question has been inexplicably neglected, and the elementary conceptual work has not been done. We consider this question through exploring the implications of free-will-related justice. We see that there are actually two questions of very different scope here, and that two distinct notions of binarity need to be distinguished. In the process, the plausibility of considering justice as a binary notion is evaluated. [source]

Linguistic Anthropology at the End of the Naughts: A Review of 2009

AMERICAN ANTHROPOLOGIST, Issue 2 2010
Francis Cody
ABSTRACT, Here I consider some of the major themes that emerged in linguistic anthropology in 2009, focusing on intersections with other disciplinary fields. Research on globalization, citizenship, publics, footing, and register formation shows how linguistic anthropology has developed a distinctive set of tools to address broad questions in the human sciences. The subdiscipline remains centrally concerned with the semiotic qualities specific to language and the forms of social life that these qualities enable. "Language" has not yet dissolved into a weak adjective in quite the same way that "culture" or "society" seem to have done, and much of the most sophisticated conceptual work on the semiotics of life lived collectively continues to focus on the concrete aspects of this multifaceted phenomenon. Linguistic anthropology maintains a relatively stable theoretical core compared to its subdisciplinary siblings, even if few of us would agree on what constitutes the limits of the field. [source]

The Eye of the Expert: Walter Benjamin and the avant garde

ART HISTORY, Issue 3 2001
Frederic J. Schwartz
In ,The Work of Art in the Age of its Technical Reproducibility' of 1935/36, Walter Benjamin considers the effects of new conditions of production and commerce on the response to visual stimuli and on the structure of works of art, contrasting reception characterized by ,aura' with that characterized by ,distraction', the gaze of the (bourgeois) art lover with that of the working ,expert'. This essay represents Benjamin's theory of a new and positive form of mass spectatorship; in it he seeks to rise to the challenge of conservative critiques of culture, finding revolutionary potential and cognitive value in seemingly debased modes of apperception. By focusing on the notion of the ,expert', this article seeks to plot new coordinates by which to map the complex conceptual work involved in Benjamin's influential theses. The ,expert' was a key figure in the radical retheorization of cultural values in Weimar Germany, one implicated in the crisis of the traditional intelligentsia as well as in the processes of professionalization that affected fields from the arts to the sciences. Benjamin and those close to him in the Constructivist avant garde felt the pressures of new conditions of intellectual work, and traces of this can be found in the essay. There is also evidence of another process affecting the nature of thought in modernity: as objects of knowledge came to be approached within the parameters of narrowly defined professional concerns, both the origins and uses of the knowledge produced inevitably tended to fall into the blind spots of professional vision. By studying his contact with and borrowings from bodies of professional expertise, this article will question the extent of Benjamin's awareness of changing conditions of knowledge in the twentieth century.
