This article examined the personal profiles of the Heads of Government of countries in South/North America and how they communicated with their audiences on institutional measures to contain COVID-19. Analyses were carried out on data collected from Twitter from November-2019 to November-2020. This study includes: i)quantitative analysis, measuring categories and emphases in the communication of tweets, retweets, likes, and comments on matters relevant to the pandemic; ii)qualitative analysis that allowed evaluating speeches to identify political interference and the effectiveness of communication at critical moments of the pandemic. It was possible to infer that each president has his singularities and understanding about Social Media’s use as a more direct communication tool with his audience. It was also found that successful communication is not directly proportional to the volume of messages on Twitter, but to socio-political aspects and institutional leadership that can make a difference in Social Media in combating COVID-19.

In this article, I conduct a quantitative analysis of negative concord in Buckie, a relic dialect from the northeast of Scotland, and compare these findings with transported varieties of English in North America. Two major results arise from the analysis. First, Buckie has high rates of use of negative concord to indeterminates within the same clause, as do all the dialects included in the study. Second, negative concord in other environments is found in certain varieties in the New World that have no counterparts in the Old World. I suggest that the quantitative similarities can be explained in terms of the primitive status of negative concord in vernacular varieties of English, in combination with a shared linguistic heritage during the colonial period. The qualitative differences demonstrate that contexts of linguistic heterogeneity in North America during the early colonization period led to an extension and restructuring of the original rules.

Scalable Synthesis

Mathuralure (1) is the major sex pheromone component of the pink gypsy moth Lymantria mathura, a potentially devastating invasive species to North America. To support population monitoring of this moth, a gram-scale synthesis of (–)-mathuralure (1) was developed. This process relies on coupling an alkynyl lithium species with a chloroepoxide and provides access to the natural product in a 10% yield over 10 steps.
