First Steps Towards Hearts and Minds? USAID\u27s Countering Violent Extremism Policies in Africa

The United States government has adopted new approaches to counter violent extremist organizations around the world. “Soft security” and development programs include focused educational training for groups vulnerable to terrorist recruitment, norm messaging through local radio programming, and job creation in rural communities. This article evaluates the effectiveness of one set of these multi-vectored, community-level programs through analysis of data from 200 respondents in two similar, neighboring cities in northern Mali, Africa. The data show that residents in Timbuktu who were exposed to the programming for up to five years displayed measurably altered civic behavior and listening patterns in comparison with their counterparts in the control city of Dire which had no programming (controlling for potential covariates including age, ethnicity, and political and socioeconomic conditions). However, there was little measurable difference between the groups in terms of their cultural identities and attitudes towards the West. This article suggests that the process of “winning hearts and minds” can be effective at certain levels but may require extended time and dedicated resources to have higher-level results

Natural Disasters, Climate Change, and Tourism Panel Discussion

Tourism, an economic sector of great global importance, faces a “trifecta” of challenges given its propensity towards locations that are densely populated and susceptible to extreme weather events that will be exacerbated by climate change. While climate change is a global problem, its impacts will manifest differently at the local scale and will likely necessitate responses that are specific to individual tourism communities. Subsequently, efforts to increase resilience for tourism destinations should be strongly tied to efforts to build their communities’ resilience, as some of the factors that increase community resilience have also been shown to increase the resilience of the tourism sector

Strong civil-society as a double-edged sword: Sitting trailers in post-Katrina

Submission procedures: Weatherhead Center affiliates are encouraged to submit papers to the Working Paper Series. Manuscripts are assessed on the basis of their scholarly qualities-the extent of original research, the rigor of the analysis, the significance of the conclusions-as well as their relevance to contemporary issues in international affairs. Manuscripts should range between 25 and 80 double-spaced pages and must include an abstract of no more than 150 words. Authors should submit their paper as an e-mail attachment in a standard word processing application (Microsoft Word or Word Perfect) to the Publications Department at [email protected]. where a number of communities and individuals expressed their opposition to hosting such trailer sites both publicly and privately. We analyze the final list of city-approved sites to track which factors were correlated with larger (or smaller) numbers of trailers and trailer sites per zip code bloc. Our data show that areas which displayed greater levels of social capital, as evidenced by voluntaristic activities such as turning out to vote, were slated for fewer trailers, controlling for race, income, flood damage, area, population density, and other relevant factors. Despite theories uncritically connecting denser social capital with more rapid rebuilding, areas of strong civil society weakened the city's ability to recover quickly by forcing it to invest more effort in locating amenable sites for temporary housing

Intelligence within BAOR and NATO's Northern Army Group

During the Cold War the UK's principal military role was its commitment to the North Atlantic Treaty Organisation (NATO) through the British Army of the Rhine (BAOR), together with wartime command of NATO's Northern Army Group. The possibility of a surprise attack by the numerically superior Warsaw Pact forces ensured that great importance was attached to intelligence, warning and rapid mobilisation. As yet we know very little about the intelligence dimension of BAOR and its interface with NATO allies. This article attempts to address these neglected issues, ending with the impact of the 1973 Yom Kippur War upon NATO thinking about warning and surprise in the mid-1970s. It concludes that the arrangements made by Whitehall for support to BAOR from national assets during crisis or transition to war were - at best - improbable. Accordingly, over the years, BAOR developed its own unique assets in the realm of both intelligence collection and special operations in order to prepare for the possible outbreak of conflict

Target-Based Identification of Whole-Cell Active Inhibitors of Biotin Biosynthesis in Mycobacterium tuberculosis

SummaryBiotin biosynthesis is essential for survival and persistence of Mycobacterium tuberculosis (Mtb) in vivo. The aminotransferase BioA, which catalyzes the antepenultimate step in the biotin pathway, has been established as a promising target due to its vulnerability to chemical inhibition. We performed high-throughput screening (HTS) employing a fluorescence displacement assay and identified a diverse set of potent inhibitors including many diversity-oriented synthesis (DOS) scaffolds. To efficiently select only hits targeting biotin biosynthesis, we then deployed a whole-cell counterscreen in biotin-free and biotin-containing medium against wild-type Mtb and in parallel with isogenic bioA Mtb strains that possess differential levels of BioA expression. This counterscreen proved crucial to filter out compounds whose whole-cell activity was off target as well as identify hits with weak, but measurable whole-cell activity in BioA-depleted strains. Several of the most promising hits were cocrystallized with BioA to provide a framework for future structure-based drug design efforts

TFAW survey II: six newly validated planets and 13 planet candidates from K2

Searching for Earth-sized planets in data from Kepler's extended mission (K2) is a niche that still remains to be fully exploited. The TFAW survey is an ongoing project that aims to re-analyse all light curves in K2 C1-C8 and C12-C18 campaigns with a wavelet-based detrending and denoising method, and the period search algorithm TLS to search for new transit candidates not detected in previous works. We have analysed a first subset of 24 candidate planetary systems around relatively faint host stars (10.9 < Kp < 15.4) to allow for follow-up speckle imaging observations. Using vespa and TRICERATOPS, we statistically validate six candidates orbiting four unique host stars by obtaining false-positive probabilities smaller than 1 per cent with both methods. We also present 13 vetted planet candidates that might benefit from other, more precise follow-up observations. All of these planets are sub-Neptune-sized with two validated planets and three candidates with sub-Earth sizes, and have orbital periods between 0.81 and 23.98 d. Some interesting systems include two ultra-short-period planets, three multiplanetary systems, three sub-Neptunes that appear to be within the small planet Radius Gap, and two validated and one candidate sub-Earths (EPIC 210706310.01, K2-411 b, and K2-413 b) orbiting metal-poor stars

Thrombolytic removal of intraventricular haemorrhage in treatment of severe stroke: results of the randomised, multicentre, multiregion, placebo-controlled CLEAR III trial

Background: Intraventricular haemorrhage is a subtype of intracerebral haemorrhage, with 50% mortality and serious disability for survivors. We aimed to test whether attempting to remove intraventricular haemorrhage with alteplase versus saline irrigation improved functional outcome. Methods: In this randomised, double-blinded, placebo-controlled, multiregional trial (CLEAR III), participants with a routinely placed extraventricular drain, in the intensive care unit with stable, non-traumatic intracerebral haemorrhage volume less than 30 mL, intraventricular haemorrhage obstructing the 3rd or 4th ventricles, and no underlying pathology were adaptively randomly assigned (1:1), via a web-based system to receive up to 12 doses, 8 h apart of 1 mg of alteplase or 0·9% saline via the extraventricular drain. The treating physician, clinical research staff, and participants were masked to treatment assignment. CT scans were obtained every 24 h throughout dosing. The primary efficacy outcome was good functional outcome, defined as a modified Rankin Scale score (mRS) of 3 or less at 180 days per central adjudication by blinded evaluators. This study is registered with ClinicalTrials.gov, NCT00784134. Findings: Between Sept 18, 2009, and Jan 13, 2015, 500 patients were randomised: 249 to the alteplase group and 251 to the saline group. 180-day follow-up data were available for analysis from 246 of 249 participants in the alteplase group and 245 of 251 participants in the placebo group. The primary efficacy outcome was similar in each group (good outcome in alteplase group 48% vs saline 45%; risk ratio [RR] 1·06 [95% CI 0·88–1·28; p=0·554]). A difference of 3·5% (RR 1·08 [95% CI 0·90–1·29], p=0·420) was found after adjustment for intraventricular haemorrhage size and thalamic intracerebral haemorrhage. At 180 days, the treatment group had lower case fatality (46 [18%] vs saline 73 [29%], hazard ratio 0·60 [95% CI 0·41–0·86], p=0·006), but a greater proportion with mRS 5 (42 [17%] vs 21 [9%]; RR 1·99 [95% CI 1·22–3·26], p=0·007). Ventriculitis (17 [7%] alteplase vs 31 [12%] saline; RR 0·55 [95% CI 0·31–0·97], p=0·048) and serious adverse events (114 [46%] alteplase vs 151 [60%] saline; RR 0·76 [95% CI 0·64–0·90], p=0·002) were less frequent with alteplase treatment. Symptomatic bleeding (six [2%] in the alteplase group vs five [2%] in the saline group; RR 1·21 [95% CI 0·37–3·91], p=0·771) was similar. Interpretation: In patients with intraventricular haemorrhage and a routine extraventricular drain, irrigation with alteplase did not substantially improve functional outcomes at the mRS 3 cutoff compared with irrigation with saline. Protocol-based use of alteplase with extraventricular drain seems safe. Future investigation is needed to determine whether a greater frequency of complete intraventricular haemorrhage removal via alteplase produces gains in functional status
