Foreign direct investment in Africa : policies also matter
No full textAfrica has not succeeded in attracting much foreign direct investment in the past few decades. When countries did attract multinational companies, it was principally because of their (abundant) natural resources and the size of their domestic market. Angola, Cote d'Ivoire, Nigeria, and South Africa have traditionally been the main recipients of foreign direct investment in Sub-Saharan Africa. But the author shows that a few Sub-Saharan countries have generated interest among international investors by improving their business environment. In the 1990s, Mali, Mozambique, Namibia, and Senegal attracted substantial foreign direct investment--more so than countries with bigger domestic markets (Cameroon, Republic of Congo, and Kenya) and greater natural resources (Republic of Congo and Zimbabwe). Mali and Mozambique, which improved their business climate spectacularly in the 1990s, did so with a few strategic actions: liberalizing trade, launching an attractive privatization program, modernizing mining and investment codes, adopting international agreements on foreign direct investment, developing a few priority projects that had multiplier effects on other investment projects, and mounting an image-building effort in which political figures such as the nation's president participated. These actions are similar to those associated with the success of other small countries with limited natural resources, such as Ireland and Singapore about 20 years ago.Environmental Economics&Policies,Economic Theory&Research,Governance Indicators,International Terrorism&Counterterrorism,Foreign Direct Investment

No full textInhibition of the miR-143/145 cluster attenuated neutrophil differentiation of APL cells
No full textMicroRNAs can influence hematopoietic cell lineage commitment and aberrant expression of hematopoietic miRNAs contributes to AML pathology. We found that miR-143 and miR-145 expression is significantly repressed in primary AML patient samples as compared to neutrophils of healthy donors. Further analysis revealed impaired neutrophil differentiation of APL cells upon inhibition of miR-145 expression. Lastly, we identified p73 as transcriptional regulator of miR-143/145 during neutrophil differentiation of APL cells. Our data suggest that low miR-145 levels in APL, possibly due to aberrant expression of p73 transcription factors, contribute to the differentiation block seen in this disease

An overview on Global Positioning Techniques for Harsh Environments
No full textAbstract This chapter presents strategies and techniques used to increase the sensitivity of global navigation satellite system (GNSS) receivers in order to make them usable in harsh environments, such as urban canyons, light indoor scenarios, deep forests, or space. It discusses the assistance that can be provided to the GNSS receiver through communication channels to ease the acquisition and tracking processes. Assisted GNSS is a consolidated standard, but other kinds of assistance and signal processing techniques can improve the ability of the receiver to process the signal at a low signal-to-noise ratio. The chapter introduces the common approaches to increase the sensitivity at the acquisition stage, discussing the impact on the accuracy of the delay and Doppler shift estimation, and the intrinsic limitation to coherent and noncoherent integration time extension. Techniques to increase robustness to low signal-to-noise ratio scenarios are presented, considering the structure of new and modernized GNSS signals
