Safety perceptions of residents are often analysed through surveys and compared with factual crime developments. Using the Dutch city of Rotterdam as an urban context of improved crime levels, this article provides a critique on standardised surveys in the research of safety perceptions and its presupposed connection to factual crime. Contrasting survey results from the Rotterdam Safety Index with qualitative data from 64 in-depth interviews in four districts, the qualitative narrative contradicts findings from the survey and implies more nuanced and diversified policy responses to safety issues. Because of the tendency of surveys to connect safety perceptions to factual crime, their unsuitability to catch subtle perceptions and their inability to expose new viewpoints, we argue for de-quantification: a lesser dependency on—but not a repeal of—survey data in this area, supplemented by a periodic qualitative approach in the research of crime and safety information (qualitative monitoring).  相似文献

This article examines the policies implemented by both the Obama and Trump Administrations toward Cuba to evaluate the claim that the ‘Thaw’ of relations between Washington and Havana represents a significant change in US foreign policy toward the island nation. Despite the appearance that the change in policy is a fundamental shift, I argue that the changes in US policy toward Cuba under both Obama and Trump represent changes in the means for pursuing the same historical objectives pursued by the Washington for the past few decades. In other words, the overall strategy and objective of US hegemony in Cuba is the same, with the only change being the means for achieving these ends. The central implication of this is that the ‘Thaw’ in relations between Cuba and the US represents a new, more ‘consensual’ means to instigating the same objective of provoking American-orchestrated political, economic, social and ideological changes in the island nation.  相似文献

There is an increasing demand for herbal medicines in weight loss treatment. Some synthetic chemicals, such as sibutramine (SB), have been detected as adulterants in herbal formulations. In this study, two strategies using near infrared (NIR) spectroscopy have been developed to evaluate potential adulteration of herbal medicines with SB: a qualitative screening approach and a quantitative methodology based on multivariate calibration. Samples were composed by products commercialized as herbal medicines, as well as by laboratory adulterated samples. Spectra were obtained in the range of 14,000–4000 per cm. Using PLS‐DA, a correct classification of 100% was achieved for the external validation set. In the quantitative approach, the root mean squares error of prediction (RMSEP), for both PLS and MLR models, was 0.2%w/w. The results prove the potential of NIR spectroscopy and multivariate calibration in quantifying sibutramine in adulterated herbal medicines samples.  相似文献
