Information about the spread of the coronavirus is circulated through various information channels in the society, both mainstream media, alternative media, social media, and daily conversation. One of the information channels that is widely used and referenced by the public is social media. Dissemination of information about the expanse of the coronavirus on social media is arranged by various individuals. This study will explain the disemination of information relating to covid-19 in terms of the social class of the reader. In this study, we use critical discourse analysis as a method for analyzing data. This study finding is that the information circulation about coronavirus in social media is class bias.

'Stalin's Secret Weapon' is a gripping account of the early history of the globally significant Soviet biological weapons program, including its key scientists, its secret experimental bases and the role of intelligence specialists, establishing beyond doubt that the infrastructure created by Stalin continues to form the core of Russia's current biological defense network. Anthony Rimmington has enjoyed privileged access to an array of newly available sources and materials, including declassified British Secret Intelligence Service reports. The evidence contained therein has led him to conclude that the program, with its network of dedicated facilities and proving grounds, was far more extensive than previously considered, easily outstripping those of the major Western powers

This book examines the specific issue of whether or not there is a nexus (link or point of convergence) between international opium and heroin trafficking and terrorist networks operating in or from Afghanistan. Since 9/11 many public officials and others have made definitive statements concerning an alleged nexus between criminal narcotics trafficking and terrorist networks in Afghanistan. Although some anecdotal and circumstantial evidence suggests that a linkage between drug traffickers and international terrorists may exist in Afghanistan, the question is whether a convincing case based on sound empirical data can be made regarding a nexus or linkage between Afghan-based terrorists and national or internationally-based drug traffickers.

As the Internet represents an essential lever for growth, most of the brands have today, a Facebook account, an Instagram, or even a full website dedicated to them. Therefore, despite their strong need of control, brands belonging to the luxury sector need to adapt to this new communication and distribution tool. Nevertheless, the adoption of the Internet by luxury brands raises a paradox: the luxury is sensory and exclusive while the Internet is virtual and democratic. Indeed, it is advisable to wonder if the use of the digital as a distribution channel (e-commerce) still make high-end brands able to put forward an elitist image as well as the prestige and the rarity of their products. Consequently, this study focuses on the e-business of top of the range brands and more precisely investigates the attitudes and the perceptions of the French people regarding the sales of luxury products on the Internet. The research methodology is based on a quantitative method: data were collected by using a self-administered questionnaire in an online survey during a two weeks period. The findings revealed that the whole sample was very connected: out of 100 people, 100 have already bought something online. Also, the results of this investigation showed that the most important benefits of the e-shopping of high-end products are the time-saving and the greater choice than in stores whereas the most cited drawbacks are the impossibility to see, touch or try the products and the pleasure to buy in stores. ; A internet é indiscutivelmente uma alavanca para o crescimento empresarial, daí todas as marcas têm hoje uma conta no Facebook, na Instagram e até mesmo uma página própria no sítio da internet.

Ainda assin, a adoção do canal internet no mundo de produtos de luxo sofre de um paradoxo: o luxo é emocional e exclusivo enquanto que a internet é virutal e democrático. Questiona-se, pois, se o uso de internet como canal de distribuição (e-commerce) consegue transmitir a imagem elitista como também o prestígio e a raridade dos seus produtos. Este estudo foca o comércio electrónico das marcas de topo e mais precisamente, investiga as atitudes e as percepções dos franceses na compra de produtos de luxo via internet.

Os resultados encontrados foram muito consistentes: dos 100 respondentes, todos compraram algo via internet. O resultado mais importante ainda é que a compra on-line representa uma enorme poupança de tempo como também permitir confrontar maior variedade de escolha do que nas lojas. O ponto mais fraco indicado pelo estudo é a impossibilidade de ver, tocar e experimentar o produto na compra on-line como também o próprio prazer de comprar nas lojas.
