Why did the world succeed in eradicating smallpox? Though eradication is a global public good, theory suggests that it should not have been vulnerable to free riding. Some countries, however, lacked the capacity to eliminate smallpox. Success thus depended on the other countries providing assistance. Theory suggests that this public good also should not have been vulnerable to free riding. However, financing proved challenging, even though the global benefit-cost ratio for eradication exceeded 400:1. Contrary to what theory suggests, what may have been the greatest achievement of international cooperation ever was not inevitable. Indeed, it very nearly failed.  相似文献

This report concerns a four-month-old white female infant who exhibited abnormal feeding behavior and EKG irregularities during a newborn sucking behavior study. The immediate post-birth history showed an irregular heart rate on two occasions, but a cardiac consultation elicited no unusual findings. During sucrose sucking conditions, the heart rate increased with a beat-to-beat variation of 50 beats per minute, noted to be due to premature atrial beats. At 39 days, an EKG showed a marked sinus tachycardia of 156, a PR interval of 0.08, QRS of 0.05 and a QT of 0.26. The infant was diagnosed as a sudden infant death syndrome (SIDS) following an unexpected death at home. Subsequent cardiac pathology revealed an anomalous tract between the right atrium and the atrioventricular (AV) bundle which formed an extensive bypass of the AV node (atrio-His tract), and two accessory AV connections between the left atrium and posterior left ventricle. These findings are consistent with the Wolff-Parkinson-White syndrome type A. Only further studies can determine whether such abnormal feeding behavior with EKG irregularities can be used to identify infants who are at high risk for sudden death.  相似文献

Abstract: This research is intended to assess the ability of UV–visible microspectrophotometry to successfully discriminate the color of dyed hair. Fifty‐five red hair dyes were analyzed and evaluated using multivariate statistical techniques including agglomerative hierarchical clustering (AHC), principal component analysis (PCA), and discriminant analysis (DA). The spectra were grouped into three classes, which were visually consistent with different shades of red. A two‐dimensional PCA observations plot was constructed, describing 78.6% of the overall variance. The wavelength regions associated with the absorbance of hair and dye were highly correlated. Principal components were selected to represent 95% of the overall variance for analysis with DA. A classification accuracy of 89% was observed for the comprehensive dye set, while external validation using 20 of the dyes resulted in a prediction accuracy of 75%. Significant color loss from successive washing of hair samples was estimated to occur within 3 weeks of dye application.  相似文献

Abstract

This article presents an overview of current understandings in the study of political and civic engagement and participation, drawing in particular on innovations which have emerged from the Processes Influencing Democratic Ownership and Participation (PIDOP) project. For the purposes of the article, ‘engagement’ is defined as having an interest in, paying attention to, or having knowledge, beliefs, opinions, attitudes, or feelings about either political or civic matters, whereas ‘participation’ is defined in terms of political and civic participatory behaviours. The different forms that political and civic engagement and participation can take are outlined, and the factors that are related to different patterns of engagement and participation are reviewed. These factors operate at different levels, and include distal macro contextual factors, demographic factors, proximal social factors, and endogenous psychological factors. An integrative model covering all four levels of factors is outlined. Some findings from the secondary analysis of existing data-sets (including the European Social Survey and the International Social Survey Programme) in the PIDOP project are also reported. These findings show that engagement and participation vary as a function of complex interactions between macro, demographic, and psychological factors. It is argued that multi-level integrative theories, such as the one proposed in the current article, are required to understand the drivers of political and civic engagement and participation, and that policies and interventions aimed at enhancing citizens' levels of engagement and participation need to take this multi-level complexity into account.  相似文献

Over the past five years the Government of Rwanda has placed renewed emphasis on increasing the number of female military personnel and gender mainstreaming the Rwanda Defence Force (RDF). This article examines the efforts made by the RDF since 2007 to meet these strategic requirements and integrate women into the national security organ. It is suggested that, in spite of Rwanda's success in bringing women into the political sphere, women are still reluctant to join the military. It is argued that prevailing societal values and attitudes, conflicting narratives within official discourse about the role of women as security actors, resource constraints and the RDF's emphasis on ‘gender equality’ are barriers to achieving RDF goals. Drawing on in-depth interviews with RDF military personnel and government officials, as well as documentary research, the article first provides an overview of the Rwandan government's approach to mobilizing women to securitize the state, before examining how the RDF aims to progress the Women, Peace and Security (WPS) agenda nationally and within local communities. The article then reflects on some of the factors that are hindering the recruitment and retention of female military personnel.  相似文献

Effective targeting of transfers is a key issue in public policy to combat poverty. Much faith is presently placed in self-targeting mechanisms such as public employment schemes supported by food-for-work transfers. Where targeting errors have been observed, these are usually attributed to mismanagement of key operational details, such as the project's wage rate. Using a unique data set from rural Ethiopia, we demonstrate that targeting errors may also have structural causes in some low-income countries. We hypothesise that imperfect factor markets generate a predictable dispersion across households in reservation wage rates that breaks down the unconditionally positive relation between income and shadow wages on which the theory of self-targeting public employment programmes rests. Our results confirm that the inaccuracy of FFW targeting stems from the fact that, in rural Ethiopia, higher income households are endowed with more labour per unit of land or animal. Due to poor factor markets in land and livestock these labour-abundant households have lower marginal labour productivity on farm, thereby depressing the reservation wage rates they find acceptable for FFW participation.  相似文献

Improvisation can be an important element of mediation practice, and there are several ways in which mediation practice correlates to improvisational performance. In this article, two mediation experts and two skilled jazz musicians explore the improvisational aspects of mediation. Two central themes emerge: (1) mediators often use improvisational techniques, and (2) by being improvisational, mediators can create environments that would encourage the parties themselves to be improvisational. We argue that practitioners can enhance their effectiveness as mediators by mastering improvisational skills.  相似文献
