  • This study introduces the first method that determines tropospheric ozone column directly from a space-based instrument. This method is based on the physical differences in the Total Ozone Mapping Spectrometer (TOMS) measurement as a function of its scan-angle geometry. Tropospheric ozone in September-October exhibits a broad enhancement over South America, the southern Atlantic Ocean, and western South Africa and a minimum over the central Pacific Ocean. Tropical tropospheric ozone south of the equator is higher than north of the equator in September-October, the southern burning season. Conversely, ozone north of the equator is higher in March, the northern burning season. Overall, the ozone over the southern tropics during September-October is significantly higher than over the northern tropics. Abnormally high tropospheric ozone occurs over the western Pacific Ocean during the El Nino season when the ozone amounts are as high as the ozone over the Africa.

  • It is generally acknowledged that the Steel Catenary Riser (SCR) is the most cost-effective riser type for deep-water offshore fields among various risers, including the SCR, flexible riser, and hybrid riser. However, in West Africa, the SCR type may not be suitable for FPSO systems because the large vertical motion of the floater brings about a considerable riser dynamic response. In this paper, an SCR system is designed for the FPSO in the West African field, where the use of a hybrid riser has been preferred. The proposed SCR configuration fulfills the design criteria of the API, such as the strength check and fatigue life. Moreover, a sensitivity analysis is also carried out to improve the certainty in the SCR design of a deep-water FPSO. The parameters affecting the strength and fatigue performance of the SCR are considered.

  • South Africa is a multiracial country where different cultures and languages coexist. Culture can be conveyed through language. Language conditioning is also social conditioning, and through words we make sense of our own and others' experience. In this paper I investigate the meaning of two culturally significant words: (English) peace and (African) ubuntu. Data findings will show how L2 speakers of English, when asked to define peace, promptly operate a process of transfer of the meaning from their mother-tongue Xhosa equivalent - uxolo - to its English equivalent. Ubuntu, an African word which encompasses traditional African values, has no counterpart in English. I will also argue how, in the ongoing process of globalisation, English is playing a predominant role in promoting cultural homogenization.

  • Purpose - This paper attempts to provide an understanding of practice of franchising in eight countries - USA, UK, Australia, Brazil, China, Malaysia, South Africa and Nigeria. The bases of the review are: number of systems and outlets, employment generation, annual turnover, GDP contribution, legal and regulatory frameworks and country-specific franchise business practice nuances. Research design, data and methodology - the paper is descriptive, highlighting elements of the business practice that distinguish one country from another. Documentary data - mainly industry publications supplemented by empirical literature - was used for the review. Result - Although there are commonalities in the technical design and implementation of franchise business practice - especially the business model type - differences exist in terms of legal and regulatory frameworks guiding the industry across the eight countries studied. Conclusion - There are no two countries that have the same franchise practices. Franchise markets in the developed, and to some extent, the emerging economies have saturated. Franchise markets in African countries are at infant stage and thus, these countries are strategizing to attract foreign brands into their domains.

  • This paper investigates that the Granger-causality between ODA FDI Trade, and economic growth in Senegal over the last 50 years and ODA, FDI, Trade have a impact on the Senegal's economic growth using the Vector Error Correction Model. The empirical results do confirm a directional causality between the variables considered. It also showed that an increase of ODA in the Senegal has positive effect on GDP growth and FDI, which are important factors of economic growth for poor country like Senegal. Underdeveloped nation has been suffered from insufficient savings or capital for economic growth; therefore, developed nations have to provide enough ODA to supply initial capital formation for growth, so-called, seed money. In a nutshell, ODA as a priming the pump is required and expanded continuously for Africa country's economic growth.

  • Liberalization may be described as the opening up of the economy to the outside world by relaxing government trade and economic policy restrictions to allow imports. In Kenya, this took place in the early 1990s and it had negative and positive effects on businesses manufacturing and retailing clothing and textiles. This case study narrates what has happened over the last 20 years to businesses in Nairobi, Kenya dealing in clothing and textiles. Some of the original businesses have closed down and been replaced by new ones. More small scale Kenyan businesses have been started dealing in clothing imports from the East and West selling both new and second hand clothes. There has been increased employment in the small scale clothing and textiles sector in garment making and retailing. All in all, liberalization has forced large and medium scale textile manufacture to change strategy so that they target selling to the export market more than to the local market.

  • The symbiotic association between fungus-gardening termites Macrotermes and its fungal symbiont has a moderate degree of specificity-although the symbiotic fungi (Termitomyces) form a monophyletic clade, there is not a one-to-one association between termite species and their fungus-garden associates. Here, we aim to determine the origin and phylogenetic relationships of Termitomyces in Oman. We used sequences of the internal transcribed spacer region (ITS) and the nuclear large subunit ribosomal RNA (LSU rRNA, 25S) gene and analyzed these with sequences of Termitomyces from other geographic areas. We find no evidence for more than a single colonization of Oman by Termitomyces. Unexpectedly, we find Termitomyces in Oman is most closely related to the symbiont of M. subhyalinus in West Africa rather than to those of geographically closer populations in East Africa.
