This article seeks to demonstrate that the field of entrepreneurship/small business can be characterized as fully mature, a view contrasting one proposed by Kuratko. Evidence of the achievement of full maturity and marginal legitimacy is given based on benchmarks in the development of the field. In addition, this article adds additional support to the concept of partial legitimacy on which Katz and Kuratko agree. Building from these analyses, a theoretical life cycle model for the growth of disciplines in general is offered, using entrepreneurship as the example. The major consequence of entrepreneurship's full maturity is identified as the growing centrality of the business‐school based discipline of entrepreneurship in relation to the emerging entrepreneurship efforts across campuses, and the implication of this centrality for the discipline of entrepreneurship is discussed.  相似文献

The pace, complexity, and globalization of change requires attention to the future. The change of millennia — the coming of the year 2001 — provides an opportunity, a psychological focus, for a global review of past achievements and problems and a unique chance to assess and reflect on future issues and opportunities.Unfortunately, there is as yet no mechanism or information utility to support a worldwide effort to study past achievements and problems or future issues and opportunities. Although there are many individual, isolated, special purpose, and one-time study efforts underway, there is no international system that can provide coherence or continuity to these studies, including feedback and sharing of information, and, in particular, the systematic exploration of future possibilities and policy alternatives. With growing interest in the future, the spread of instantaneous and global communications, the advent of powerful new nondeterministic modeling techniques, the ability to evoke, capture, and share information and perceptions with systematic questioning techniques and software, the proliferation of data bases, and knowledge visualization, it is now possible for futurists, scholars and others around the world to interact globally and take a fresh look at the future possibilities and policies in ways not previously possible.As the World Bank provides an ongoing system for research and feedback to improve economic policy, so too the United Nations University could provide an ongoing system for the improvement of futures research and its application to the policy process. According to a series of interviews, questionnaires, and meetings with leading futurists and scholars around the world, the proposed “Millenium Project” has the potential to become such a system.This study had as its principal objective determining the design of an information system that could effectively tap contributors, worldwide, to focus on lessons of the past that bear on world issues and the potential of future developments for intensifying or mitigating these and future issues. The first phase of the feasibility study was both methodological and substantive. Worldwide panels of experts contributed their judgments about the method or process of organizing the project; and the system that emerged from this interaction was applied in a prototype study to the issues of growing world population and the environment.During the first phase of the feasibility study, we found that:
1. 1. The Millennium Project is feasible and likely to be helpful to many institutions in examining and resolving policy issues at several levels. An overview of the project design and objectives appears in Section 2 of this article.
2. 2. Organizations that have an issues scanning function, or have a mandate to keep abreast of a broad range of futures thinking, have a need for access to a non-political, scholarly, and international system of future studies. Such organizations have requested continued participation in the second and third phase of this feasibility study, as well as establishing formal relations with the full Millennium Project.
3. 3. While several questions remain, the design features of a system to collect judgments using the Delphi process that were suggested by the international panel (outlined elsewhere in this report) form a straight forward operational system. Among the remaining questions are the design and use of international information systems and data bases, integration with quantitative techniques such as system modeling, the requirements for special study teams, and institutionalization and financial support. The design of the operational system is described in detail in Section 3 of this report.
4. 4. Cost estimates have been made for establishing international panels and collecting and analyzing information they provide using the Delphi process. Several assumptions are required. If a maximum of four topics are addressed in a particular year, each of the four panels consists of 150–200 people, the staff is kept to a base of three people with an additional 1.5 per panel, and advisors are paid an honorarium of $1.500, then the cost of this element of the full scale Project is likely to be approximately $900,000 per year. While communications modes are important in terms of timing and information access, the costs of communications are the smallest of the Project's cost elements. Detail of our cost estimates appear in Section 7 of this report.
This is not the final feasibility study report, but only a report on part of Phase I. As such, it contains our initial findings about how the Project might be organized. We welcome comments from the reader. Please consider this as work in progress.  相似文献

Studies of ‘futures’ have hitherto focused on those that are predictable and ‘tame’, and on those that are unpredictable and ‘wild’. Here we consider a new class, the ‘feral’; which are expectations that things might be made worse by risk-based actions. The type case is the nuclear accident at Three Mile Island, where operatives assumed that what was unfolding was of a sort described in their manual, and discovered too late that responses based on that assumption were making the situation worse. In this paper we review the idea of ‘feral’ and how it applies to futures, and discuss the different modes of engagement (or non-engagement) with feral futures. To make feral futures manageable, we suggest two ideas from other spheres of activity. Zen is a practice and philosophy which enables us to drop our preconceptions and thereby to respond to emerging, unprecedented situations. Aesthetics articulates a particular way to sense and appreciate realities intuitively, again enabling a direct response. The combination of Zen and aesthetics with scenario practice in the tradition of Pierre Wack provides a promising mode of response to emerging feral futures.  相似文献

This article tests the linearity assumption underlying the popular heterogeneous autoregressive model for realized volatility (HAR-RV). We implement a consistent model specification test that is robust to both distributional and model misspecification. We find that, using a nonparametric HAR-RV (NPHAR-RV), we are unable to reject the null of linearity.  相似文献

Reductionist scientific methodology has been at the forefront of economics research for much of the past 50 years. This short essay argues that recent discoveries in genetic engineering show that the study of complex phenomena might not be best served by such an approach, but rather by one that takes into consideration more evolutionary approaches. This provides a tremendous opportunity for the field of bioeconomics to establish itself as a major school of though, going into the future.  相似文献

One of the most important features of the Australian economy in the past two decades has been the structural deterioration of labour market performance, reflected in both an increase in the average rate of unemployment and an outward shift in the Beveridge Curve, which depicts the relationship between unemployment and vacancies. This article attempts to uncover some of the causes for this structural deterioration, in terms of the factors affecting the UVrelationship. We find that the Beveridge Curve shifted out around 1974, consistent with an increase in the equilibrium rate of unemployment which is generally agreed to have occurred around that time. Using gross labour market flow data, we also investigate the determinants of the equilibrium Beveridge Curve in the 1980s. We find that the Beveridge Curve shifted further outwards in the 1980s. The most important determinant of this shift was the decline in the search effectiveness of the unemployed, reflected in the increasing incidence of long-term unemployment. Partially offsetting this influence during this time were the declining labour force participation of men, and the very large increases in female employment.  相似文献

Lighter skin complexions may function as a form of capital, particularly for women, in marriage markets. The existence of a preference for light skin for marital partners is an index of the presence of colorism or color bias in a given society. This paper reports on a detailed examination of marital advertisements that appeared in India’s Sunday Times on a single day in March 2013. It asks how often skin shade is mentioned in the advertisements placed among those seeking grooms and those seeking brides, how those mentions are distributed by the reported age of the prospective marital partner, and the type of language used to describe the individual’s complexion. The study finds that skin shade is described far more often in advertisements placed by prospective brides or their families than prospective grooms or their families, and, whenever complexion is mentioned, the possession of lighter skin shades.  相似文献

Risk management and governance:: a post-normal science approach   总被引:2,自引:0,他引:2  
In this essay we consider the problems of risks and governance in the light of three well-known examples: the ‘Seveso' accident involving dioxin; the BSE epidemic; and the licensing of genetically modified maize. These form a natural progression, from hazards that are ‘classical', manageable mainly by ‘applied science', to those that are totally post-normal. The new hazards typified by genetically modified maize, but including many others such as untested toxic chemicals, pose serious challenges to governance. The erosion of trust in the established institutions could lead to paralysis of innovation and also of government.  相似文献
