Background: The world has watched with growing alarm as scientists in the U.K.  Identified a new coronavirus variant that appears to be more contagious than, and genetically distinct from, other established variants. The scientists keep collecting the facts about the new variant and its impact on symptom, severity, mortality, and vaccine efficacy. Objective: This review shed light on the SARS-CoV-2 2020 virus that appeared in Britain and South Africa in December 2020, known as B.1.1.7. Furthermore, it highlights the main differences between the new COVID-19 version (B.1.1.7) and the other strains of the virus. Conclusion: Mutations are still happening in the SARS-CoV-2 virus as the RNA viruses cause many changes in the proteins of the spikes of the virus and other parts. The British variant has 23 mutations, compared with the version that erupted in Wuhan, that renders the virus more contagious; however, these mutations do not change the disease's severity.

The case of former Yugoslavia and its successors is specific and a bit different from the other post-conflict societies. First, retributive model of justice is carried out, or it should be carried out, before the International Criminal Tribunal in the Hague. The question is how to start the process of searching for the truth and reconciliation inside and between societies, groups and individuals in newly established countries. There is no such a model in the world, like these in South Africa and some countries in Latin America, which can be applied here, because in this case we are talking about five states, from which at least three were in the war. Also, the character of these conflicts covers the diapason from international conflicts to internal aggression and civil war.

The several forms of preferential mating, such as cross-cousin marriage, sororate and levirate, are well known and have been reported from all the ethnographic provinces of the world. Lately Lowie and Rivers have devoted special chapters in their books on social organization to the comparative study of these important institutions. Lowie has pointed out that there is strong evidence for the correlation of sororate and levirate. The later publication of Rivers hardly serves to make these matters any clearer than Lowie's work. Although the latter scholar, with Tylor and others, recognized the close connexion existing between sororate and levirate, the evidence at his disposal did not allow him to arrive at a similar conclusion with regard to the other forms of preferential marriage. Accordingly he had to treat them, for the time being, as institutions of independent origin.

Two millenarian events, one in Brazil (Canudos Rebellion, 1897) and the other in South Africa (Bulhoek Massacre, 1921) have inspired two works of narrative fiction: Mario Vargas Llosa's The War of the End of the World (1981) and Mike Nicol’s This Day and Age (1992). In both novels the events are presented from the perspectives of both the oppressed landless peasants and the oppressors, who were the ruling élites. In both instances, governments which purported to be models of enlightenment and modernity resorted to violence and repression in order to uphold their authority. Vargas Llosa's novel was written in the Latin American tradition where truth and fiction mingle indistinguishably while in the South African novel fictional elements override historical truth.

This article analyses the proceedings of eight International Sanitary Conferences which were convened between 1851 and 1894 to address the danger that cholera epidemics posed to Europe. These conferences are examined in the context of the intellectual and institutional changes in scientific medicine and in the light of the changing structure of internationalist endeavours that took place in the second half of the nineteenth century. The article shows that the International Sanitary Conferences were as much spaces of co-operation as they were arenas where differences and boundaries between disciplines, nations, and cultures were defined. Furthermore, it seeks to shed light on a broader tension of the period. On the one hand, the fact that the world was growing together to an unprecedented extent due to new means of transportation enabled Europeans to establish and expand profitable commercial and colonial relations. On the other hand, this development increased the vulnerability of Europe – for example to the importation of diseases. The perception that the world was becoming increasingly interconnected was thus coupled with the need for controllable boundaries. The conferences attempted to find solutions as to how borders could be secured without resorting to traditional barriers; like semipermeable membranes they should be open for some kinds of communication but closed for others.

Given that the number of qualified programmers cannot be increased drastically and rapidly, software managers in most parts of the world will likely have to live with a human resources shortage in this area for some time. One way of dealing with this shortage is to form global software teams in which members are recruited from all over the world and software is developed in a distributed manner. Forming such a global software teams can have many advantages. In addition to alleviating the problems caused by scarcity of human resources, programmers on a global team would be free to work without being confined by physical location. Although forming global software teams may increase the size of the pool of programmers that can be recruited, both team quality and software quality are issues of great concern. Some software companies would prefer to establish a global software team with software programmers in developing countries, such as China, Poland, and South Africa (Sanford, 2003). Given the tremendous salary gap between skilled and unskilled developers or between developed and developing countries, it is not difficult to see that maintaining a team with a proportion of less experienced members significantly reduces running expenses (Figure 1). On the other hand, however, it would present the problem of managing inexperienced programmers. This chatper shares our experience of managing inexperienced software teams in China. To simplify our discussion, we deal separately with the two topics of inexperienced software teams and global software teams. However, it should be noted that a global software team can be composed of both inexperienced and experienced software subteams. We categorize the problems in these two types of software teams which will help software managers learn more how to manage the two types of software teams.

Young people throughout the world are an afterthought of policy and program interventions. In Africa, and particularly in third world nations, the irony of sloganizing youth as the cream or the future of the nation exists alongside tendencies and behaviors that impede their development towards being responsible and full citizens which rather aggravates youth underdevelopment and marginalization. It is an undisputed fact that young people have been the vanguard of liberatory struggles that resulted in dismantling colonialism and apartheid. On one hand, the chapter examines strategies adopted to overcome intergenerational poverty by using narratives (daily experiences of youth) of post-apartheid South Africa. On the other hand, the chapter highlights the uncertainties and frustrations of living in a democratic South Africa, with its failure to open up opportunities for their socio-economic growth, the apartheid discriminatory system, and survival.

Purpose – This paper aims to research as to how Twitter is influential as an electronic word-of-mouth (e-WOM) communication tool and thereby affecting movie market. In present days, social media is playing an important role in connecting people around the globe. The technology has provided a platform in the social media space for people to share their experiences through text, photos and videos. Twitter is one such online social networking media that enables its users to send and read text-based messages of up to 140 characters, known as “tweets”. Twitter has nearly 200 million users and billions of such tweets are generated by users every other day. Social media micro-blogging broadcasting networks such as Twitter are transforming the way e-WOM is disseminated and consumed in the digital world. Twitter social behaviour for the Hollywood movies has been assessed across seven countries to validate the two basic blocks of the honeycomb model – sharing and conversation. Twitter behaviour was studied for 27 movies in 22 different cities of seven countries and for six genres with a total tweets of 9.28 million. The difference of Twitter social media behaviour was compared across countries, and “sharing” and “conversation” as two building blocks of the honeycomb model were studied. t-Test results revealed that the behaviour is different across countries and across genres. Design/methodology/approach – The objective of the paper is to analyse Twitter messages on an entertainment product (movies) across different regions of the world. Hollywood movies are released across different parts of the world, and Twitter users are also in different parts of the world. The objective is to hence validate “conversation” and “sharing” building blocks of the honeycomb model. The research is confined to analysing Twitter data related to a few Hollywood movies. The tweets were collected across nine different cities spanning four different countries where English language is prominent. To understand the Twitter social media behaviour, a crawler application using Python and Java was developed to collect tweets of Hollywood movies from the Twitter database. The application has incorporated Twitter application programming interfaces (APIs) to access the Twitter database to extract tweets according to movies search queries across different parts of the world. The searching, collecting and analysing of the tweets is a rather challenging task because of various reasons. The tweets are stored in a Twitter corpus and can be accessed by the public using APIs. To understand whether tweets vary from one country to another, the analysis of variance test was conducted. To assess whether Twitter behaviour is different, and to compare the behaviour across countries, t-tests were conducted taking two countries at a time. The comparisons were made across all the six genres. In this way, an attempt was made to obtain a microscopic view of the Twitter behaviour for each of the seven countries and the six genres. Findings – The findings show that the people use social media across the world. Nearly 9.28 million tweets were from seven countries, namely, USA, UK, Canada, South Africa, Australia, India and New Zealand for 27 Hollywood movies. This is indicative of the fact that today, people are exchanging information across different countries, that people are conversing about a product on social media and people are sharing information about a product on social media and, thus, proving the hypothesis. Further, the results indicate that the users in USA, Canada and UK, tweet more than the other countries, USA and UK being the highest in tweets followed by the Canada. On the other hand, the number of tweets in Australia, India and South Africa are low with New Zealand being the lowest of all the countries. This indicates that different countries’ users have different social media behaviour. Some countries use social media to communicate about their experience more than in some other country. However, consumers from all over the world are using Twitter to express their views openly and freely. Originality/value – This research is useful to scholars and enterprises to understand opinions on Twitter social media and predict their impact. The study can be extended to any products which can lead to better customer relationship management. Companies can use the Internet and social media to promote and get feedback on their products and services across different parts of the world. Governments can inform the public about their new policies, benefits of governmental programmes to people and ways to improve the Internet reach to more people and also for creating awareness about health, hygiene, natural calamities and safety.

AbstractThis article links classifying activities to practices of emotion. Re-reading al-Tanūkhī’s collectional-Faraj baʿd al-shidda(“Deliverance after hardship”), it focuses on the arrangement of the book on the one hand, and on how the involved emotions are handled on the other. This double approach suggests that by connecting the fields “order” and “emotion” the scope of knowledge with regard to the Arabic scholarly tradition can be reviewed and extended. Against the background of the widespread impulse to arrange and classify, the emotional spectrum is given a framework which generalizes, even rationalizes, the feeling itself. In turn, emotional representations in the stories shed light onto the fragile mechanisms of encyclopedic presuppositions and on definitions in general. Since both concepts are affected and shaped by narrative structures, story-telling can be considered as a significant means of structuring the world.

This paper intends to discuss the inter-religious dialogue and the Prophet’s engagement with the ‘Other’. Both dialogue and faith-based reconciliation provide a way to mankind by which the world will become peaceful place to live. In this violence torn world, reconciliation on the basis of faith is needed, so that unity may be created out of diversity. This paper argues that interfaith dialogical theory profits from a deep understanding of moral psychology and social learning theory. The paper highlights that reconciliation belongs to Abrahamic legacy, and also focuses on how Islam established and come up with advanced civilizations characterized by relatively harmonious co-existence between Muslims, Christians and Jews. It is through reconciliation that we regain our humanity. To work for reconciliation is to live and to show others what their humanity is. The paper also shed light on faith-based reconciliation in its Islamic perspective. It is this context the present paper has been drafted.
