In Making Science (1992) I make the distinction between two types of knowledge: research frontier knowledge and core knowledge. Core knowledge
is the small body of knowledge for which the entire scientific community treats as indisputable facts. The research frontier
is all new knowledge which makes claim to being facts but in practice there is no consensus on this knowledge. The two types
of knowledge are linked together by the evaluation process. Most frontier knowledge turns out to be insignificant and is ignored.
A small part of frontier knowledge is taken as candidates for the core and evaluated. Most of this knowledge turns out to
be “wrong.” Thus the important data of Jacobs ( 1989) loses a good deal of its impact because he forces it into a theory which
he calls “social control”: a theory for which there is no evidence.

Looking inside public involvement: how is it made so ineffective and can we change this? 总被引:1,自引:0,他引:1
Communities and community groups across Britain are faced withever-increasing opportunities to participate,yet such engagement is widely viewed as ineffective and themotives behind it viewed with suspicion. This article suggeststhat ineffectiveness is often at least partly the result ofdecisions that are taken within the wider policy-making processesthat develop and surround public involvement, and presents away of analysing such management. This analysis also pointsto a strategy for being more effective, through attempting tobecome more active players in the larger policy-making game. 相似文献

Practical computation of the minimum variance unbiased estimator (MVUE) is often a difficult, if not impossible, task, even
though general theory assures its existence under regularity conditions. We propose a new approach based on iterative bootstrap
bias correction of the maximum likelihood estimator to accurately approximate the MVUE. Viewing bootstrap iteration as a Markov
process, we develop a computational algorithm for bias correction based on arbitrarily many bootstrap iterations. The algorithm,
when applied parametrically to finite sample spaces, does not involve Monte Carlo simulation. For infinite sample spaces,
a nonparametric version of the algorithm is combined with a preliminary round of Monte Carlo simulation to yield an approximate
MVUE. Both algorithms are computationally more efficient and stable than conventional simulation-based bootstrap iterations.
Examples are given of both finite and infinite sample spaces to illustrate the effectiveness of our new approach.

In insurance markets, the uninsured can generate a negative externality on the insured, leading insurance companies to charge higher premia. Using a novel panel data set and a staggered policy change that introduces exogenous variation in the rate of uninsured drivers at the county level in California, we find that uninsured drivers lead to higher insurance premia: a 1 percentage point increase in the rate of uninsured drivers raises premia by roughly 1%. We calculate the monetary fine on the uninsured that would fully internalize the externality and conclude that actual fines in most US states are inefficiently low. 相似文献

The aim of this study is to examine the relationship between impairment, disabling barriers and risk factors relating to hate crime incidents. The study analyses quantitative data collected in 2011–2012 where there were 81 incidents of disability hate crime reported in the Tyne and Wear area of England. The research discovered that in the Tyne and Wear region people with learning difficulties have a greater likelihood of experiencing hate crime than do people with other impairments. Although there was no significant difference between impairment and types of hate crime incidents recorded (i.e. verbal abuse/harassment, violence and criminal damage), there were distinct differences between police and victim support responses to victims which correlated to impairment categories (p ≤ 0.05). The study concludes by suggesting that owing to specific disabling barriers experienced by people with learning difficulties, this group is at increased risk of being victimised and is less likely to receive support from criminal justice agencies. 相似文献

This paper develops a quantitative model of internal city structure that features agglomeration and dispersion forces and an arbitrary number of heterogeneous city blocks. The model remains tractable and amenable to empirical analysis because of stochastic shocks to commuting decisions, which yield a gravity equation for commuting flows. To structurally estimate agglomeration and dispersion forces, we use data on thousands of city blocks in Berlin for 1936, 1986, and 2006 and exogenous variation from the city's division and reunification. We estimate substantial and highly localized production and residential externalities. We show that the model with the estimated agglomeration parameters can account both qualitatively and quantitatively for the observed changes in city structure. We show how our quantitative framework can be used to undertake counterfactuals for changes in the organization of economic activity within cities in response, for example, to changes in the transport network. 相似文献

This paper is concerned with the relatively new interest in national planning in the United States. The effects of the Arab oil embargo and price increases, impending scarcities of minerals, inflation, unemployment, and other problems seem to be reversing the American public's negative views of planning by the Federal government. Assuming that negative sentiments are still strong and aware of the difficulty of institutional change, the authors submit a modest proposal for initiating a formal system of indicative national planning.The proposal is based upon an analysis of the economic challenges facing the United States and the apparent inability of the Federal government to respond effectively to change. The solution is seen as the need for an economic intelligence activity coupled to the formulation of ‘inventories of policy alternatives’, with a minimum of structural change or expansion in governmental structure.The recent Humphrey-Javits proposal for national planning is discussed briefly and critically. 相似文献

Political participation in the rural United States has often been narrowly defined within the confines of electoral politics. Increasingly, participants in rural US social movements have highlighted the shortcomings of democracy defined purely in terms of electoral politics in favour of a more participatory model of politics that focuses on the social and cultural rights of those who are often formally or informally excluded from the liberal definition of citizenship. This article highlights the process of claiming rights as cultural citizens in a political context where there are efforts through the formal political system—usually in the form of ballot referendums at the state or local level—to further limit the rights of specific constituencies such as gay, lesbian and transgendered individuals or immigrants. A second focus of this article is on the dynamics of solidarity and alliance building between different kinds of social movements acting in concert to push for cultural rights and then formal rights for each other's constituencies. The article specifically seeks to illustrate how two organizations that share quite different constituencies and agendas can effectively collaborate in regional and state-wide campaigns in the rural state of Oregon, while also honestly discussing their differences and difficulties in working together. 相似文献
