Reframing science and other local knowledge traditions 总被引:2,自引:0,他引:2
David Turnbull 《Futures》1997,29(6):551-562
By recognizing science as a set of local practices it becomes possible to ‘decentre’ it and develop a framework within which all knowledge systems can be equitably compared. It is argued that all knowledge traditions are spatial in that they link people, sites and skills. In order to ensure the continued existence of the diversity of knowledge traditions rather than have them absorbed into the great imperialist archive we need to enable disparate knowledge traditions to work together through the creation of a third space in which the social organization of trust can be negotiated. 相似文献

Demand for wireless telephony is huge and the potential for GMPCS, in particular, is widely recognized. However, the most serious problems to the introduction of GMPCS are not technical, nor financial, but are rather the political and regulatory barriers—notably fear of bypass and security concerns. Inmarsat does not believe that there should be any a priori limit to the number of GMPCS operators offering satellite capacity to national service providers. The market can best determine which will be successful. However, before countries open their markets, they will need to be convinced that it is in their interest to do so. 相似文献

We focus on determining the impacts of government programs on farms’ technical inefficiency levels. We use Kumbhakar's stochastic frontier model that accounts for both production risks and risk preferences. Our theoretical framework shows that decoupled government transfers are likely to increase (decrease) DARA (IARA) farmers’ production inefficiencies if variable inputs are risk decreasing. However, the impacts of decoupled payments cannot be anticipated if variable inputs are risk increasing. We use farm‐level data collected in Kansas to illustrate the model. 相似文献

Empirical studies of hedonic housing prices show that the spatial maximum likelihood estimation (MLE) method is preferable to the traditional ordinary least squares (OLS) hedonic method. Current computing capabilities restrict the MLE method to relatively small data sets. This paper circumvents this limitation by coupling the spatial MLE method with block bootstrapping, a form of Monte Carlo simulation that accounts for spatially dependent data. Blocks are created based on monthly and census tract information for resampling. For each month, we obtained 50 resamples of 750 observations from a data set of 15,727 residential properties to compare OLS and MLE empirical results. We find that the spatial MLE method consistently outperforms the traditional OLS method under these simulated conditions and that air quality matters irrespective of the method used. 相似文献

Economists and other social scientists are calling for a reassessment of the impact of international trade on labor markets
in developed and developing countries. Classical models of globalization and trade, based upon the international exchange
of finished goods, fail to capture the fragmentation of much commodity production and the geographical separation of individual
production tasks. This fragmentation, captured in the growing volume of intra-industry trade, prompts investigation of the
effects of trade within, rather than between, sectors of the economy. In this paper we examine the relationship between international
trade and the task structure of US employment. We link disaggregate US trade data from 1972 to 2006, the NBER manufacturing
database, the Decennial Census, and occupational and task data from the Dictionary of Occupational Titles. Within-industry
shifts in task characteristics are linked to import competition and technological change. Our results suggest that trade has
played a major role in the growth in relative demand for nonroutine tasks, particularly those requiring high levels of interpersonal
interaction. 相似文献

This paper evaluates the effects of binding regulatory restraints on the rate of performance-based management compensation within a banking framework in which a primary function of bank management teams is to monitor loans in order to eliminate deadweight default losses. Available management teams are endowed with heterogeneous levels of monitoring efficiencies, and obtaining services from more efficient monitoring teams requires payment of higher rates of performance-based compensation. In equilibrium, a fraction of banks choose to employ management teams that monitor. With or without binding capital requirements, imposing binding restraints on the allowed rate of performance-based compensation results either in lower bank efficiency or in a reduced fraction of monitoring banks and, hence, lower aggregate loan quality. 相似文献

Applying the Shin z measure of market efficiency to the relatively new person‐to‐person internet betting exchanges, Smith, Paton, and Vaughan Williams found “significantly lower market biases” compared to bookmaker‐dominated markets. A reduced favorite‐longshot bias is interpreted as evidence that insider trading on the exchanges “is not widespread” and “not as commonplace … as is sometimes portrayed in the media.” Given that the Shin measure assumes “betting with bookies,” whereas the exchanges represent “betting without bookies,” the present study employs the notion of ‘significant mover’ to empirically test for the presence of ‘known loser’ insider trading on the exchanges where traditional notions of bookmaking do not apply. Findings indicate that, far from being less problematized by insider trading compared to racetrack betting, activity aimed at profiting from “known losers” may be potentially commonplace on the exchanges. This includes profiting from horses that are unplaced. This study offers new insight into the efficiency of betting markets. 相似文献

Loyalty discounts and rebates are pricing schemes that offer incentives to buyers for reaching or exceeding certain sales thresholds. In the case of market share discounts, thresholds are expressed as a percentage of the buyer’s total purchase requirements. Although market share discounts may have exclusionary effects under certain circumstances when a seller has significant market power, there are plausible non‐exclusionary reasons for offering them as well. Two such reasons – rent extraction and inducing downstream selling effort – are explored in this paper. The paper considers the case of a manufacturer who sells a differentiated good through a network of heterogeneous, non‐exclusive retailers. The manufacturer offers market share discounts to induce non‐contractible selling effort such as brand‐specific information or customer service from those retailers who possess certain unobservable characteristics. In some instances, market share discounts induce increased selling effort and improve market performance as compared to linear pricing. In other instances, they have no effect on aggregate benefits, but merely shift the rents created by induced selling effort upstream to the manufacturer. In no instance, as long as the producers of substitute goods retain sufficient sales to remain viable, do market share discounts impair market performance. 相似文献
