This article argues for an innovative methodology to appraising (ex ante) longer-term strategic research and development (R&D) investments. This methodology reflects the inherent value of such R&D in terms of opening up opportunities (but not obligations) for investment in new technological areas with potentially substantial returns. Although corporate R&D managers and public administrators describe the merits of long-term research on these grounds, only recently has the qualitative argument been replaced by the foundations of a methodology capable of quantifying this inherent value of R&D. Such a methodology could also facilitate a transition toward the use of more appropriate discount rates other than the unvarying rates of traditional methodologies.  相似文献

Microcredit schemes have been increasingly incorporated into development policies that aim to de-marginalise rural China. Based on in-depth ethnographic fieldwork, this paper examines the various roles that microcredit programmes play in development outcomes at the local level. It demonstrates that microcredit has the ability to facilitate the de-marginalisation of certain individuals/groups, while simultaneously (re)producing inequalities, thus exacerbating the marginalisation of others. This finding demonstrates that microcredit does not induce uniform, predictable and linear development through the integration of marginal places and people into the formal financial system and wider economy. Instead, microcredit programmes reflect and reinforce the interlocking sets of unequal relationships that are the root cause of marginality and underdevelopment in China. Through this detailed analysis of the contradictory outcomes of Chinese microcredit programmes, this paper provides the basis for a wider relational critique of microcredit as an intervention aimed at inducing a specific type of market-oriented linear development that is beneficial for some and detrimental for others.  相似文献

ABSTRACT

The aim of this article is to critically consider the effectiveness of the “Financial War on Terrorism” on the funding streams of the Islamic State of Iraq and Levant (ISIL). The article begins by identifying that the origins of the “Financial War on Terrorism” can be found in the international efforts to tackle money laundering. It then moves on to consider if the “Financial War on Terrorism” is able to tackle the funding streams of ISIL. The article concludes that the “Financial War on Terrorism” is no longer fit for the purpose to tackle the funding streams of ISIL.  相似文献

This article addresses the puzzle of electoral support for corrupt politicians in emerging democracies by examining citizens’ varying attitudes toward political corruption. We make an important theoretical distinction between perceptions of and tolerance for corruption, and argue that these different attitudes vary across individuals depending on whether they are political insiders or outsiders. We test our theory using Afrobarometer survey data from 18 sub‐Saharan African countries and find that individuals included within clientelistic networks simultaneously perceive corruption as ubiquitous and are more tolerant of malfeasance. Meanwhile, those individuals with partisan or ethnic ties to the incumbent are less likely to consider corruption as widespread. Finally, we explore whether variation in attitudes toward corruption influences citizens’ voting behavior, and find that insiders are less likely to “vote the rascals out.”  相似文献

Anthony King thought and wrote a great deal about British prime ministers and political leadership more generally. But in contrast to the way in which single papers embodied his contribution to our understanding of ‘government overload’, ‘executive‐legislative relations’ and ‘career politicians’, his contribution to our understanding of the prime ministership was defined by a body of work. This essay explores that body of work and identifies some of the themes that characterised it. It then relates King's work to claims about the ‘presidentialisation’ of the office, as well as the importance of the expectations surrounding contemporary prime ministers. As Britain grapples with the challenge of Brexit, we should all take note of his counsel against expecting too much in the way of ‘strong’ prime ministerial leadership.  相似文献

We use an institutional rational choice approach to help us understand how prime ministers in the UK make cabinet appointments and the implications for prime ministerial power. Assuming that prime ministers attempt to form a cabinet so as to get an overall package of policies as close as possible to their ideal, we show why the trade-offs they face are so complex, why apparently common-sense rules for making appointments might not always work well and why apparently strange choices made by prime ministers might actually be rational. Acknowledging the power prime ministers derive from their ability to appoint, we argue that the literature commonly fails to distinguish between power and luck, where lucky prime ministers get their way because they happen to agree with colleagues.  相似文献

This paper investigates authorities’ relative counterterrorism effectiveness focusing on its behavior over time, its impact on casualties and property losses. Using data on transnational terrorism from the ITERATE database (1973–2003) and discrete choice models, relative counterterrorism effectiveness is evaluated controlling for a variety of terrorists’ and authorities’ effort attributes. The probability of a terrorist incident being stopped by the authorities has increased in the examined period. Furthermore, a negative relationship between authorities’ ability to stop an incident and the probabilities of casualties and damages is identified. However, the “ability to stop” exerts higher impact on the probability of property losses compared to casualties.  相似文献

Studies of US trade policy legislation focus on the effect of constituents on trade policy voting and give less weight to institutions such as political parties. To demonstrate that political parties affect voting, I compare the votes of politicians who share constituency characteristics but differ in political party affiliation. This approach requires less reliance on assumptions about, or empirical measures of, constituents’ trade preferences. The results demonstrate that political parties play a significant role in legislative voting on trade policy. Theories of political economy therefore should incorporate how constituency interests and partisan pressures affect legislative voting.  相似文献

In unison, fingerprinting and DNA analysis have played a pivotal role in forensic investigations. Fingerprint powders that are available on the market can come in a range of colors and with specific properties. This study evaluated the efficiency of DNA extraction from samples coated with 3 brands of fingerprint powders: Lightning, Sirchie, and SupraNano, covering a range of colors and properties. A total of 23 fingerprint powders were tested using the Chelex, Promega DNA IQ™, and Applied Biosystems™ PrepFiler™ DNA extraction protocols. The DNA IQ™ and PrepFiler™ methods extracted higher yields of DNA in comparison to Chelex, which also accounted for better quality of PowerPlex x00AE; 21 DNA profiles recovered. There were no signs of degradation or inhibition in the quantification data, indicating that samples returning low DNA yield was due to interference during DNA extraction and not PCR inhibition. DNA profiles were recovered from the majority of fingerprint powders with only a single powder, Sirchie Magnetic Silver, failing to produce a profile using any of the methods tested. A link was observed between the DNA extraction chemistry, fingerprint powder property, that is, nonmagnetic, magnetic and aqueous, and the brand of fingerprint powder. Overall, the DNA IQ™ method was favorable for nonmagnetic fingerprint powders, while magnetic fingerprint powders produced more DNA profiles when extracted with the PrepFiler™ chemistry. This study highlights the importance of screening DNA extraction chemistries for the type of fingerprint powder used, as there is not a single DNA extraction method that suits all fingerprint powder brands and properties.  相似文献

ABSTRACT

Social movements increasingly embrace agroecology as an integral part of food sovereignty. This essay has two related aims: first, to highlight the barriers to agroecology and explore how these can be overcome; second, to deepen understandings of how agroecology can strengthen movements for food sovereignty or extend neoliberal governance. I ground these questions by examining state and social movement agroecological programs in Guatemala. I argue that strict rejection of conventional inputs and market production, in addition to insufficient state investment and redistribution, creates barriers to participation among a rural peasantry whose livelihoods have been transformed by decades of scientific, market-led development. Facing these limits, agroecology can work to strengthen food sovereignty movements, but can also reinforce the neoliberal food regime by promoting resilience and indigenous agriculture as sufficient to resolve the food crisis.  相似文献
