Recent work has applied the Narrative Policy Framework (NPF) to examine narrative strategies in policy debates on social media platforms. We contribute to the literature by applying the NPF to fracking policy debates in New York using well-established Natural Language Processing tools, including sentiment analysis. We combine this computational approach with a qualitative hand-coding of pro- and antifracking Twitter influentials. This approach allows us to consider a much larger corpus of tweets over a much longer time frame than has been done thus far. We adapt and test NPF propositions related to the use of the devil/angel shift strategies before and after a major state-wide policy change, that is, a state-wide moratorium on high volume hydraulic fracturing or fracking. Overall, we find evidence for the use of the devil shift narrative strategy by the pro-fracking coalition aimed at the Governor prior to the moratorium. After the moratorium, the relative percentage of Tweets containing devil shift sentiments decreases as the pro-fracking coalition generally downshifts in its use of angel shift language without a corresponding increase in devil shift language, whereas, conversely, the anti-fracking coalition generally downshifts in its use of devil shift language without a general increase in angel shift language. When we shifted our analysis to Tweets containing fracking and the Governor, we found a similar postban decrease in devil shift language among anti-fracking users. Our findings offer lessons for using computational tools in the NPF as an approach to expand analytic ability and for the operationalization of concepts such as narrative strategies and policy entrepreneurs.  相似文献

This paper aims to examine the role of individual resources in explaining African political participation. If political participation is costly and requires inputs in terms of individual resources, and citizens in young developing country democracies face comparatively high participation costs and have more limited individual resource endowments than citizens in more established democracies, a resource approach to political participation should be particularly relevant in the African setting. On the contrary, however, empirical findings drawing on recent data for more than 27,000 respondents in 20 emerging African democracies suggest weak explanatory power of the resource perspective. Often, the relatively resource poor actually participate to a greater extent than the more resource rich. The results are encouraging in that they suggest fairly broad-based political participation, but also call attention to the need to evaluate the motivational forces behind the decision to take part.  相似文献

In Norway, as in many other high-cost OECD countries in a geographical and cultural periphery, policy-makers seem to have given up attempts at attracting large numbers of foreign R&D investments. Instead, a major focus of innovation policies is to help companies internationalise yet with an aim to maintain or even increase their level of R&D and other innovation activities nationally. Based on case studies of eight Norwegian companies and their motives for and experiences with internationalisation of R&D, this article questions this policy. From the perspective of the companies, many factors explain how, why and where they carry out their R&D activities.   相似文献

随着我国人口老年化的加剧,作为人口占多数的农村养老问题也受到更多的关注。由于家庭结构变化,中国家庭4-2-1模式的普遍存在,传统家庭养老面临巨大挑战,新型的农村社区居家养老应运而生。但由于法律建设的不健全,农村社区养老在实践中面临困境。要解决这一问题,就要基于法律的思维,构建完善的农村社区居家养老模式。  相似文献

This paper contributes to ard a better understanding of innovation in the service sector by focusing on the disparate nature of R&D in the U.S. service sector as learned through case studies of the U.S. telecommunications, financial services, systems integration services, and research and development testing services industries. Based on this understanding of the nature and scope of R&D therein, a new policy-oriented model of innovation specific to the service sector is posited. Also, policy recommendations are offered with regard to the public sector’s collection and interpretation of R&D data related to the service sector.   相似文献

In forensic identification, the use of foot dimensions to predict stature is a requisite. For Taiwanese male stature prediction, available information about stature estimation using foot dimensions is still lacking. Therefore, the primary purpose of this study was to establish Taiwanese adult male stature prediction models for various foot dimensions. A total of 2,072 male 3D foot models were collected and the subjects' ages ranged from 18 to 59 years old. Thirteen foot dimensions for each foot were utilized in this study. Bilateral differences were tested using paired t-tests. Stature predictions based on different foot dimensions were conducted using simple linear and stepwise regression methods. The results showed significant bilateral differences in the majority of the selected foot dimensions (p < 0.001). Foot length had the highest positive correlation with stature in the right and left foot. Using length-related dimensions generated better prediction accuracy (0.356 < R2 < 0.533, 4.193 < SEE < 4.928), whereas the worst accuracy was observed with angle-related dimensions (0.001 < R2 < 0.023; 6.072 < SEE < 6.137) when employing a single foot dimension to estimate Taiwanese male stature. Stepwise regression analysis results indicated that the coefficient of determination was improved to 0.590 and 0.593 by applying five and six foot parameters to predict stature, respectively. The findings of the present study suggest that these stature estimation equations can be applied to predict Taiwanese male stature in the forensic science field.  相似文献
