Detecting threshold effects in price transmission
The analysis of price transmission plays a key role in understanding markets integration. This helps identify the nature of the relationship between geographically distant markets and cross-commodity price transmission, as well as the impact of liberalization policies and the identification of regions exposed to systemic shocks. This technical note contributes to the debate between symmetric and asymmetric price transmission and proposes to present the traditional and new approaches for detecting threshold effects in price transmission while focusing on their advantages and limitations. There is no one-size-fits-all method to detect threshold effects in price transmission. Experts need to select a combination of elements (context of study, the economy under consideration, data availability…) to justify the relevancy of their choice. Beyond the presentation of the methods for detecting thresholds in price transmission, we perform an application in the case of the rice market in Senegal. The results support the evidence of an asymmetric price transmission between world and domestic prices in the short-run and a symmetric transmission in the long-run.
Unit root tests: Common pitfalls and best practices
Since the seminal paper by Granger and Newbold (1974) on spurious regressions, applied econometricians have become aware of the consequences of unit roots in empirical analysis with time series data. Yet one can still find many published papers with unit root tests implemented in an inappropriate way. The objective of this Technical Note is to highlight the common pitfalls and best practices when testing for unit roots. In addition to the theoretical discussion, we provide examples using price data from Kenya, Mali, Togo, and South Africa to illustrate the procedures we think are worth following.
Africa’s Joola Shipwreck
In 2002, a government-owned Senegalese ferry named the Joola capsized in a storm off the coast of The Gambia in a tragedy that killed 1,863 people and left 64 survivors, only one of them female. The Joola caused more human suffering than the Titanic yet no scholarly research to date has explored the political and environmental conditions in which this African crisis occurred. Africa’s Joola Shipwreck: Causes and Consequences of a Humanitarian Disaster investigates the roots of the Joola shipwreck and its consequences for Senegalese people, particularly those living in the rural south. Using three summers of field research in Senegal, Karen Samantha Barton unravels the geographical forces such as migration, colonial cartographies, and geographies of the sea that led to this humanitarian disaster and defined its aftermath. Barton shows how the Sufi tenet of “beautiful optimism” shaped community resilience in the wake of the shipwreck, despite the repercussions the event had on Senegalese society and space.
Wrapping Authority
Since around 2000, a growing number of women in Dakar, Senegal have come to act openly as spiritual leaders for both men and women. As urban youth turn to the Fay?a Tij?niyya Sufi Islamic movement in search of direction and community, these women provide guidance in practicing Islam and cultivating mystical knowledge of God. While women Islamic leaders may appear radical in a context where women have rarely exercised Islamic authority, they have provoked surprisingly little controversy. Wrapping Authority tells these women's stories and explores how they have developed ways of leading that feel natural to themselves and those around them. Addressing the dominant perceptions of Islam as a con...
Le naufrage du Joola dix ans après. Chants pour les morts et les survivants
Préface d'Idrissa Diallo. Ce livre est un hommage aux morts et aux survivants du naufrage du Joola survenu dans la nuit du 26 au 27 septembre 2002, vers 23 heures, au large des côtes gambiennes. Les deux parties de l’ouvrage honorent les victimes en les unissant dans des chants, d’abord sous la forme de poèmes écrits pour la plupart peu de temps après le drame, dans l’émotion sous le choc des événements ; ensuite, en épelant tous les noms figurant sur la liste détaillée que l’auteur a contribué à établir, pour servir de litanie incantatoire invoquant les disparus et les rescapés et les sauvant ainsi de l’oubli. Les poèmes représentent des invocations, des dialogues...
Flore et végétation
La végétation naturelle est une importante source pour l’alimentation, la santé et la satisfaction des besoins énergétiques des populations. Cependant, elle est menacée par un certain nombre de facteurs biotiques et abiotiques. Face à ce constat, ENDA -Madesahel a mis en place le conservatoire botanique Michel Adanson (Mbour) pour une protection durable des ressources végétales menacées. Cependant, l’insuffisance des données scientifiques limite la gestion de la biodiversité végétale. Cette étude a pour objectif de contribuer à une meilleure connaissance de la flore, de la végétation et l’usage des plantes médicinales par la population riveraine en vue d’optimiser ...
Rubber Nanocomposites
Rubber Nanocomposites: Preparation, Properties and Applications focuses on the preparation, characterization and properties of natural and synthetic rubber nanocomposites. The book carefully debates the preparation of unmodified and modified nanofillers, various manufacturing techniques of rubber nanocomposites, structure, morphology and properties of nanocomposites. The text reviews the processing; characterization and properties of 0-, 1D and 2D nanofiller reinforced rubber nanocomposites. It examines the polymer/filler interaction, i.e., the compatibility between matrix and filler using unmodified and modified nanofillers. The book also examines the applications of rubber nanocomposites i...
