Sustainable investment in land in the Global South: What would it require from a coherence perspective? The case of Sierra Leone

Large scale acquisitions of land in the Global South have signifi-cantly increased since the millennium. It is often the case that foreign investors are involved in such acquisitions, which are commonly aimed at facilitating the export of commodities. These investments in land tend to transform conventional, rather small scale agricultural systems into large scale, industrial agricultural systems. While investment in ag-riculture in the Global South is much needed, large-scale investments in land often goes hand-in-hand with environmental and human rights re-lated challenges. As a consequence, lawyers need to address questions of sovereignty over natural resources (this paper focuses in particular on land resources), to peoples’ right to self-determination, to the responsi-bilities of the home and host states of the investors, including public-private relationships, and the role of international institutions who are involved, as well as relevant jurisprudence. This paper approaches these questions from the perspective of a theory on policy coherence for sus-tainable development.

Geheime Netzwerke im Militär 1700-1945

Die Armee ist ein zentraler Machtfaktor im Staat, militärische Informationen sind grundsätzlich gesetzlich geschützt. Das Militär bildet zudem ein soziales System mit eigenen Normen, Ritualen und Symbolen. Die hierarchische Struktur und das starke Berufsethos prägen das Militär bis heute. Innerhalb dieses Rahmens bildeten sich immer wieder geheime Netzwerke von Militärangehörigen mit abweichenden Verhaltenskodizes. Sie erregten häufig den Verdacht, gegen das eigene Militärsystem oder den Staat gerichtet zu sein. Die Autorinnen und Autoren des Bandes erkunden die Wechselwirkungen zwischen Geheimbundorganisationen, Geheimnisträgern, Verschwörern und dem Militär – von Freimaurern und Illuminaten bis zum Stauffenberg-Kreis. Das Buch enthält Beiträge in deutscher und englischer Sprache

Potential Impact of Sexual Transmission on Ebola Virus Epidemiology: Sierra Leone as a Case Study.

BACKGROUND Sexual transmission of Ebola virus disease (EVD) 6 months after onset of symptoms has been recently documented, and Ebola virus RNA has been detected in semen of survivors up to 9 months after onset of symptoms. As countries affected by the 2013-2015 epidemic in West Africa, by far the largest to date, are declared free of Ebola virus disease (EVD), it remains unclear what threat is posed by rare sexual transmission events that could arise from survivors. METHODOLOGY/PRINCIPAL FINDINGS We devised a compartmental mathematical model that includes sexual transmission from convalescent survivors: a SEICR (susceptible-exposed-infectious-convalescent-recovered) transmission model. We fitted the model to weekly incidence of EVD cases from the 2014-2015 epidemic in Sierra Leone. Sensitivity analyses and Monte Carlo simulations showed that a 0.1% per sex act transmission probability and a 3-month convalescent period (the two key unknown parameters of sexual transmission) create very few additional cases, but would extend the epidemic by 83 days [95% CI: 68-98 days] (p < 0.0001) on average. Strikingly, a 6-month convalescent period extended the average epidemic by 540 days (95% CI: 508-572 days), doubling the current length, despite an insignificant rise in the number of new cases generated. CONCLUSIONS/SIGNIFICANCE Our results show that reductions in the per sex act transmission probability via abstinence and condom use should reduce the number of sporadic sexual transmission events, but will not significantly reduce the epidemic size and may only minimally shorten the length of time the public health community must maintain response preparedness. While the number of infectious survivors is expected to greatly decline over the coming months, our results show that transmission events may still be expected for quite some time as each event results in a new potential cluster of non-sexual transmission. Precise measurement of the convalescent period is thus important for planning ongoing surveillance efforts.
