Counter‐knowledge refers to flaws in citizens' mental models arising from utilization of rumours, inappropriate knowledge structures, outdated routines or procedures. When counter‐knowledge is applied to civil servants, it may result in problems of efficiency, equity and motivation. This paper examines the relationship between counter‐knowledge and open‐mindedness to model a framework for improving city marketing and policy development. This study tested two measurement models. While the theoretical model represents the effect of counter‐knowledge on city marketing and that the latter has a negative effect on open‐mindedness, the alternative model involves that counter‐knowledge has a positive indirect impact on open‐mindedness. These relationships are examined through an empirical investigation of 203 Spanish city halls. The results show a potential positive indirect effect of counter‐knowledge on open‐mindedness through city marketing programmes. This paper clarifies the existing literature, which tries to contribute to the discussion of city marketing, and helps us to obtain meaning out of the relationship between counter‐knowledge, city marketing and open‐mindedness.

Over the years, many suggestions have been made on how to reduce the importance of family background in political recruitment. In this study, we examine the effectiveness of one such proposal: the expansion of mass education. We utilize a difference‐in‐difference strategy to analyze how a large school reform launched in Sweden in the 1950s, which lengthened schooling and postponed tracking, affected the likelihood of individuals with different family backgrounds to run for public office. The data come from public registers and pertain to the entire Swedish population born between 1943 and 1955. The empirical analysis provides strong support for the view that improved educational opportunities for individuals from disadvantaged backgrounds can be an effective means to reduce the social bias of elected assemblies. 相似文献

In 1998 the Jamuna Multi-Purpose Bridge (JMB), the largest infrastructure development project in Bangladesh was completed. Huge numbers of households were affected by the project and many were displaced. Only a handful of displaced people were resettled by the project. The JMB was the first development project in Bangladesh that included resettlement activities as an integral part of the project and introduced a resettlement action plan. In principle, the Revised Resettlement Action Plan endorsed the primary principle of Operational Directives 4:30 of the World Bank. The resettlement project's core objective was to improve the living standards of project-affected persons above their previous level, or at least reinstate their pre-project standard. To meet the goals, various grants and supports were given as compensation. The project has earned international admiration as an example for other projects to follow. This study investigates the extent to which Jamuna Multi-Purpose Bridge's compensation-based resettlement succeeded in reconstructing displaced households, and identifies discrepancies between policy and practice. It concludes with major findings and comparative analysis on the compensation principle, and provides opinions based on information gathered from the field. 相似文献

Four preparation techniques for MALDI/TOF mass spectrometry were compared to determine the ability to gather intelligence for investigations through the chemical analysis of latent fingerprints, defined as “touch chemistry.” Compatible fingerprint development processes used for identification along with new techniques are necessary to evaluate touch chemistry. Ten volunteers deposited fingerprints from solvent residues containing drugs and explosives onto microscope slides. The developers included (A) fingerprint powder, (B) MALDI matrix, (C) fingerprint powder and lifting, and (D) cyanoacrylate fuming with fingerprint powder. Qualitative identification was based on ion images and spectra. The highest average detection rates (88%) were found using methods A and B. Methods C (52%) or D (18%) had limited success. Results demonstrate the importance of imaging coupled to extracted mass spectral data in detecting analytes in deposited fingerprints. Overall, the results suggest continued development of touch chemistry applications could prove useful for gathering intelligence and forensically relevant information. 相似文献

We distinguish among three types of actions that can be taken to alleviate the consequences of natural disasters: precautionary efforts (made ex ante), relief efforts (made in the immediate aftermath of a disaster), and recovery efforts (made ex post). We argue that recognizing this distinction lessens many of the problems that the literature attributes to government intervention and hence expands the scope of government action following disasters. Relief is less likely than recovery to generate over‐supply by the government and over‐reliance by victims. 相似文献

Is there a relationship between legislators’ religious affiliations and the consistency of their voting records? Building on the theory of “the personal roots of representation,” we argue that a legislator's likelihood of switching positions depends on whether the issue is central to their personal values. We evaluate this claim using a data set including senators’ religious affiliations and “culture war” votes from 1976 to 2004 and find that different religious groups vary in their voting consistency on issues such as abortion, public prayer, and gay and lesbian rights. 相似文献

The decades since the 1970s have seen an ‘explosion of interest’ in the concept of citizenship, both as means to elucidating the compromises over demands of justice and membership which underlie communities and feed into definitions of citizenship, and the increasing instability of those communities and ideals in the modern era. While there have been as many contexts of the negotiation of citizenship as there are nations (whether real or imagined), within Canada some of the most intriguing discourses around belonging have occurred within First Nations. This article is an attempt to elucidate the struggles over citizenship and membership within one Canadian Aboriginal community, the Mohawk Nation at Kahnawake. Here, intertwined with issues of blood, ‘Indian status’ and entitlement, Kahnawake has been riven by contests over the meaning of ‘belonging’ and who should belong in this First Nation. 相似文献
