Unsuccessful Cassava Brown Streak Disease (CBSD) evaluation attempts in western Democratic Republic of Congo and implications with cassava root necrosis disease (CRND) etiology
Open Access ArticleCassava brown streak disease (CBSD) is the second most important virus disease after Cassava mosaic disease (CMD), infecting cassava (ManihotesculetaCrantz) in Africa. The disease is caused by two distinct viruses, Cassava brown streak virus [2, 3] and Ugandan Cassava brown streak virus (family, Potyviridae: genus, Ipomovirus). Transmission of CBSV from one plant to another is reported to occur through grafting CBSV-free with infected cuttings and subsequent dissemination by infected cuttings. The basic approach to control of CBSD is selecting planting material from symptomless mother plants. Graft inoculation is the most efficient and effective of the techniques for CBSD virus transmission and consequently cuttings are the most effective way of the disease spreading.
In early 2000s, cassava root necrosis similar to those of CBSD were reported in western provinces of Democratic Republic of Congo (RDC) (Kinshasa and Kongo Central) and up to date PCR diagnoses did not detect any causal agent related to the observed symptoms and the disease which was still referred as ‘CBSD-like disease’.
Due to lack of molecular data and the similarity of root symptoms with CBSD, the existence of a virus has always been suspected to be the cause of CBSD-like propagation. Thus, 2 field experiments were proposed in order to verify the existence of a systematic transmission of a possible CBSD related virus, knowing that CBSD viruses are transmitted efficiently by cuttings.
The first trial focused on the field evaluation of CBSD – like infected and apparently uninfected planting materials, while the second trial involved the importation of tanzanian CBSD resistant genotypes for evaluation in INERA Mvuazi research center under CBSD-like infection conditions.
Results of the first trial did not show a systemic transmission of any CBSD-like pathogen while CBSD-resistant parents involved in the second trial all succumbed to CBSD-like disease
Philosophy at the Beginning of the 21st Century
À la dernière moitié du 20 e siècle, la postmodernité a rejeté entièrement la notion de réalité objective et celui de vérité. On doit s'en souvenir que la vérité en dépend de ce qu’il montre et s'il n'y avait aucune réalité objective il n'y avait aucune vérité non plus. Mais aujourd’hui, au commencem ent du 21 e siècle, est survenue une nouvelle vue appelée la post post -modernité qui est un retour subtil à la modernité et qui tende trouver des choses fermes dans la réalité et des certitudes dans la pensée. Ainsi, ce courent reconnaît que notre expérien ce nous enseigne qu'il y a un monde réel qui existe indépendamment de nous, indépendamment de nos expériences, de nos pensées et de notre langue. À ce moment il semble qu'il y a une opportunité de revenir à une position réaliste, qui a du sens tant dans la science que dans la théologie. Elle fournit une vision du monde qui se veut correspondante à la réalité, cohérente en lui -même et capable à répondre systématiquement aux questions de la vie
EU Foreign Policy Identity: A Case Study on the EU’s Engagement of the Islamic Republic of Iran. College of Europe EU Diplomacy Paper 06/2019
The Joint Comprehensive Plan of Action (JCPOA) is often referred to as the biggest foreign policy success of the European Union (EU). It ended twelve years of tough negotiations, stabilising one of the most volatile regions of the world. The EU’s engagement with Iran was distinct from that of the United States or even that of its member states as it focused on promoting multilateralism and diplomatic dialogue, making the EU-Iran relationship of utmost importance for both parties involved. This paper seeks to answer the research question to what extent the EU possesses a foreign policy identity that is more than the sum of that of its member states and how it expressed this identity in its engagement with Iran. Exploring EU foreign policy identity is important because it explains what type of actor the EU is in the international system and sheds light on the decision-making process of its external action. The study argues that the EU has indeed an own distinct foreign policy identity which reflects its values such as a unique commitment to diplomatic dialogue and multilateralism as the solution to international problems as well as a guarantee to upholding the rule of law in the international system. Through a qualitative content analysis of the American, British and French press as well as expert interviews with EU officials and member states’ diplomats the existence and importance of a distinct brand of EU foreign policy identity will be demonstrated
Neural Likelihoods via Cumulative Distribution Functions
We leverage neural networks as universal approximators of monotonic functions
to build a parameterization of conditional cumulative distribution functions
(CDFs). By the application of automatic differentiation with respect to
response variables and then to parameters of this CDF representation, we are
able to build black box CDF and density estimators. A suite of families is
introduced as alternative constructions for the multivariate case. At one
extreme, the simplest construction is a competitive density estimator against
state-of-the-art deep learning methods, although it does not provide an easily
computable representation of multivariate CDFs. At the other extreme, we have a
flexible construction from which multivariate CDF evaluations and
marginalizations can be obtained by a simple forward pass in a deep neural net,
but where the computation of the likelihood scales exponentially with
dimensionality. Alternatives in between the extremes are discussed. We evaluate
the different representations empirically on a variety of tasks involving tail
area probabilities, tail dependence and (partial) density estimation.Comment: 10 page

Comparing international coverage of 9/11 : towards an interdisciplinary explanation of the construction of news
This article presents an interdisciplinary model attempting to explain how news is constructed by relying on the contributions of different fields of study: News Sociology, Political Communications, International Communications, International Relations. It is a first step towards developing a holistic theoretical approach to what shapes the news, which bridges current micro to macro approaches. More precisely the model explains news variation across different media organization and countries by focusing on the different way the sense of newsworthiness of journalists is affected by three main variables: national interest, national journalistic culture, and editorial policy of each media organization. The model is developed on the basis of an investigation into what shaped the media coverage of 9/11 in eight elite newspapers across the US, France, Italy and Pakistan
