Abstract

Social media offer unprecedented opportunities to terrorist groups to spread their message and target specific audiences for indoctrination and recruitment. In 2013 and 2014, social media, in particular Twitter, overtook Internet forums as preferred space for jihadist propaganda. This article looks into Arabic statements by Jabhat al-Nusra, Islamic State and jihadist forum administrators and online activists to argue that, beside the easier use of social media and disruption and infiltration of the forums, the conflict between the jihadist groups accelerated the migration to social media and the building of a presence on Twitter that provided relative resilience to suspensions.  相似文献

Government responses to the Covid-19 pandemic in the Nordic states—Denmark, Finland, Iceland, Norway, and Sweden—exhibit similarities and differences. This article investigates the extent to which crisis policymaking diverges from normal policymaking within the Nordic countries and whether variations between the countries are associated with the role of expertise and the level of politicization. Government responses are analyzed in terms of governance arrangements and regulatory instruments. Findings demonstrate some deviation from normal policymaking within and considerable variation between the Nordic countries, as Denmark, Finland, and to some extent Norway exhibit similar patterns with hierarchical command and control governance arrangements, while Iceland, in some instances, resembles the case of Sweden, which has made use of network-based governance. The article shows that the higher the influence of experts, the more likely it is that the governance arrangement will be network-based.  相似文献

There is no lack of surveys showing that from a high rate of breastfeeding in the industrializing world of the early 20th century, after World War II the incidence declined to a nadir around 1960. For instance only a third of the infants in the US were given their own mothers' milk. The suckling of the new born is clearly not a natural instinct but needs to be taught and supported. Even if quantitative data is hard to come by for earlier centuries, there still is ample evidence that many mothers followed a tradition of not breastfeeding themselves, especially in the early 18th century. The reasons for this are partly economical, centered on the mother's heavy workload in non-industrial and energy-poor societies. But there are also cultural background factors behind the use of wet-nurses and artificial nourishment, where medical, religious and sexual ideas blend into a persuasive set of motives imprinting in women that breastfeeding is undesirable. The sending of urban babies to wet-nurses in the countryside was in part motivated by the tough epidemic climate in the cities. Modern anthropological research shows how cultural and economic motives can be doubly effective by reinforcing each other. The paper hypothesizes that for Western Europe where we have the richest historical records there may have been a breastfeeding pattern with more extensive breastfeeding in the northern parts of the continent and more use of wet-nurses and artificial nourishment in the Catholic southern parts, and that this may be rooted in long-lasting cultural factors. In addition there may have a number of places (Iceland, the Fennoscandian Arctic) where women had difficulty breastfeeding consistently because of an especially heavy workload in a tough environment, and where this developed into normative behaviour.  相似文献

Die Anwendung des naturschutzrechtlichen Vorkaufsrechts wirft in der Praxis immer wieder Fragen auf. Dies gilt etwa für die Problematik der Rechtsnatur der Vorkaufsrechtsausübung, aber auch für die Frage, ob die zust?ndige Beh?rde verpflichtet ist, die Ausübung des Vorkaufsrechts auf solche Teile eines Grundstücks zu begrenzen, die tats?chlich für Zwecke des Naturschutzes ben?tigt werden. Fraglich ist weiterhin, welche Anforderungen an die Rechtfertigung der Vorkaufsrechtsausübung zu stellen sind. Schlie?lich sind die Auswirkungen des § 467 S. 2 BGB auf das naturschutzrechtliche Vorkaufsrecht weitestgehend ungekl?rt.  相似文献
