Running a marathon has become the motivation to achieve success and economic independence for athletes, mainly from African countries. This feeling is more evident among the black community, considering that they have been presenting better results than white athletes. The objective of the study was to analyse the ranking of marathon runners around the world, in the last 15 years considering: 1) nationality; 2) best average time of the 100 best classified runners from the Top 100, Top 50, Top 25, Top 10 and Top 3. An analysis was made to the ranking available on the International Association of Athletics Federations (IAAF) website, for the 100 best world results for both sexes, focusing on records from 2000 to 2014. The analysis was subdivided into ranking groups (Top 3, 10, 25, 50 and 100), resulting in 3000 records. African runners, Kenyan and Ethiopian, dominate the male ranking representing 70% of the total of runners in Top 100, keeping this proportion up to Top 3. African runners, Kenyan and Ethiopian, dominate the male ranking representing 70% of the total of runners in Top 100, keeping this proportion up to Top 3. The same is observed for females, however with a significantly lower percentage (34%), with Japanese, Ethiopian and Kenyan (17%) and an English athlete as the world record. The average time of a marathon has been decreasing in males more than in female competitions, both in Top 3 and Top 10, however still presenting a large gap from world records.

Institutional System

We examine questions of historical formation of the International Organization of La Francophonie as an institutional system (1950–1980). The characterization and analysis of the initial stages of the International Organization of La Francophonie institutionalization allows a better understanding of its historical and modern ideological principles. It is noted that the world system of Francophonie begins to take shape in the middle of the 20th century. We analyze various projects for the creation of the International Organization of La Francophonie, which influenced the legal structure of the organization, its traditions, as well as relations with french-speaking states and other linguistic associations (International Association of French-Speaking Journalists and Press, The Union of French Culture, The Conference of Ministers of National Education of French-Speaking States, etc.). It shows the importance of both Western European and African countries and their political leaders in the development of the Francophonie project as an international organization, as well as the leading role of France. It is noted that the whole Francophone space became the springboard of the Union’s actions, and the goal was to protect and spread the French language and Francophone culture in the world. We conclude that the process of institutionalization of the International Organization of La Francophonie has played a huge role in maintaining the status of the French language and the role of France in the global space.

This article presents an overview of GE’s HA gas turbines that represent the most reliable and efficient machines in the world for converting natural gas into electricity. In a combined cycle arrangement, these turbines provide cost-effective and clean generation that offers reliable electricity to an expanding, global population. The 7/9HA turbine is based upon the original H-class 4-stage gas turbine with exception of simplification by eliminating steam cooling. Metals chosen for the 7/9HA are proven alloys with over 50 million hours of operation on F- and H-class gas turbines. The first 9HA.01 entered commercial operation on June 17, 2016 at the Électricité de France Bouchain plant, located in the Nord Pas-de-Calais region of France. GE followed the Guinness Book of World Records’ definition for a consistent and traceable operating condition for establishing efficiency in world records. Under the oversight of Guinness World Records staff, GE set the record for the world’s most efficient combined-cycle power plant with an efficiency of 62.22% while producing more than 605 MW of electricity.

Present Case Study

The aim of the present case study was to analyse the performance data of the world’s best female ultra-triathlete setting a new world record in a Quintuple (5xIronman) and Deca Iron (10xIronman) ultra-triathlon, within and between race days, and between disciplines (cycling and running) and races (Quintuple and Deca Iron ultra-triathlon). The subject was an elite female triathlete (52 kg, 169 cm) born in 1983. At the time of her world record in Quintuple Iron ultra-triathlon she had an age of 35 years and at the time of the world record in Deca Iron ultra-triathlon 36 years old. The distribution of time spent in each discipline and transitions was 8.48% in swimming, 51.67% cycling, 37.91% running, and 1.94% transitions. There was no difference between the race days of the average speed neither in cycling nor running. The running pace had a within-day variation larger than the cycling pace, and also varied more between race days. In conclusion, the world’s best female ultra-triathlete adopted a steady (even) pacing strategy for both cycling and running, without substantial variations within- or between race days, for both the world record in a Quintuple and a Deca Iron ultra-triathlon.

Background: Age-related declines in sport performance are characteristic of all endurance and sprinting disciplines. However, it is not known if the mode of locomotion (ie, swimming, cycling or running) influences the age-related decline in sport performance in sprinting and endurance events. Methods: To examine the age-related decline in 3 different modes of locomotion (ie, swimming, cycling, and running) for endurance and sprint events, the world-best performances achieved for men in the age groups 18–39, 40–44, 45–49, 50–54, 55–59, 60–64, 65–69, 70–74, 75–79, and 80–84 y were compared in swimming (1500 and 50 m), cycling (1 h and 200 m), and running (10 and 100 m). Each performance was considered as an average speed (throughout the distance), and the age-related decline in performance was expressed as a percentage of the world record (regardless of age group) for that discipline. Results: The age-related decline in 1-h track cycling is less pronounced than in 1500-m swimming and 10-km running after 60 y. In contrast, the age-related decline was similar among the 3 locomotion modes for the sprinting events. Conclusion: The data show that the maintenance of high performance in cycling persists longer into old age than in running and swimming.

The Impact

The incorporation of a trade-labour (standards) linkage into the multilateral trade regime of the World Trade Organisation (WTO) has been persistently opposed by developing countries, including those in Africa, on the grounds that it has the potential to weaken their competitive advantage. For that reason, low levels of compliance with core labour standards have been viewed as acceptable by African countries. However, with the impact of WTO agreements growing increasingly broader and deeper for the weaker and vulnerable economies of developing countries, the jurisprudence developed by the WTO Panels and Appellate Body regarding a trade-environment/public health linkage has the potential to address the concerns of developing countries regarding the potential negative effects of a trade-labour linkage. This article argues that the pertinent WTO Panel and Appellate Body decisions could advance the prospects of establishing a linkage of global trade participation to labour standards without any harm befalling developing countries.

Use Of Social Media

Social media as a communication tool has enabled governments around the world to interact with citizens for customer service, access to information and to direct community involvement needs. The trends around the world show recognition by governments that social media content may constitute records and should be managed accordingly. The literature shows that governments and organisations in other countries, particularly in Europe, have social media policies and strategies to guide the management of social media content, but there is less evidence among African countries. Thus the purpose of this paper is to examine the extent of usage of social media by the Botswana government in order to determine the necessity for the governance of liquid communication. Liquid communication here refers to the type of communication that goes easily back and forth between participants involved through social media. The ARMA principle of availability requires that where there is information governance, an organisation shall maintain its information assets in a manner that ensures their timely, efficient and accurate retrieval. The study adopted a qualitative case study approach where data were collected through documentary reviews and interviews among purposively selected employees of the Botswana government. This study revealed that the Botswana government has been actively using social media platforms to interact with its citizens since 2011 for increased access, usage and awareness of services offered by the government. Nonetheless, the study revealed that the government had no official documentation on the use of social media, and policies and strategies that dealt with the governance of liquid communication. This study recommends the governance of liquid communication to ensure timely, efficient and accurate retrieval when needed for business purposes.

BACKGROUND In sub-Saharan Africa, underreporting of cases and deaths has been attributed to various factors including, weak disease surveillance, low health-seeking behaviour of flu like symptoms, and stigma of Covid-19. There is evidence that SARS-CoV-2 spread mimics transmission patterns of other countries across the world. Since the Covid-19 pandemic has changed the way research can be conducted and in light of restrictions on travel and risks to in-person data collection, innovative approaches to collecting data must be considered. Nearly 50% of Africa’s population is a unique mobile subscriber and it is one of the fastest growing smart-phone marketplaces in the world; hence, mobile phone platforms should be considered to monitor Covid-19 trends in the community. OBJECTIVE We demonstrate the use of digital contributor platforms to survey individuals about cases of flu-like symptoms and instances of unexplained deaths in Ethiopia, Kenya, Nigeria, Somalia, and Zimbabwe. METHODS Rapid cross-sectional survey of individuals with severe flu and pneumonia symptoms and unexplained deaths in Ethiopia, Kenya, Nigeria, Somalia and Zimbabwe RESULTS Using a non-health specific information platform, we found COVID-19 signals in five African countries, specifically: •Across countries, nearly half of the respondents (n=739) knew someone who had severe flu or pneumonia symptoms in recent months. •One in three respondents from Somalia and one in five from Zimbabwe respondents said they knew more than five people recently displaying flu and/or pneumonia symptoms. •In Somalia there were signals that a large number of people might be dying outside of health facilities, specifically in their homes or in IDP or refugee camps. CONCLUSIONS Existing digital contributor platforms with local networks are a non-traditional data source that can provide information from the community to supplement traditional government surveillance systems and academic surveys. We demonstrate that using these distributor networks to for community surveys can provide periodic information on rumours but could also be used to capture local sentiment to inform public health decision-making; for example, these insights could be useful to inform strategies to increase confidence in Covid19 vaccine. As Covid-19 continues to spread somewhat silently across sub-Saharan Africa, regional and national public health entities should consider expanding event-based surveillance sources to include these systems.

Background As it is common with the most devastating events in the world, women always seem to be at the most disadvantage position. This situation manifested during the period of COVID-19 lockdown throughout the world and Africa in particular. The purpose of this study is to explore Domestic Violence (DV) cases in African during the COVID-19 lockdown. Methods Data for this study were gleaned from an electronic literature search using various databases PubMed and BioMed Central, Web of Science, etc. Key search words were gender DV during and after COVID-19. A total of 68 records were identified during the search. However, only 46 of these sources met the inclusion criteria. Results From the review done in selected African countries which include Egypt, South Africa, Kenya, Nigeria, Ghana and Zimbabwe; it was discovered that COVID-19 lockdown across these countries worsens the already existing cases of DV. The study also noted that generally, the response of the government has been very poor in terms of dealing with DV cases in the period of COVID-19 lockdown. Conclusion The study concluded that despite the failures of government in tackling the DV pandemics, NGOs have been very active in championing the cause of those violated while also trying to provide succour to victims. Thus, the study recommended that countries in Africa need to join international initiatives in prioritising DV cases while trying to deal with the virus itself. Thus, one disease should not be traded for another.
