The importance of leaf-cutting ants is increasing in many parts of Latin America, particularly where agriculture has advanced rapidly in recent times; thus Atta capiguara, a grass-cutting species unknown as a pest in 1944, is now spreading rapidly through grassland areas of Southern Brazil. Recent studies of ant behaviour such as trail-making and leaf transport, and the chemical factors involved, fascinating purely as a research topic, may point the way to improved methods of control.

We publish below a list of writers and journalists abducted by the security forces and numbered among the ‘disappeared’ in Argentina since 24 March 1976, the date of the military coup that installed General Jorge Rafael Videla in power. Two eye-witness accounts illustrate the way in which such abductions usually take place. Finally, Robert Cox, editor-in-exile of the daily newspaper Buenos Aires Herald, describes how independent-minded journalists and the families of los desaparecidos ( ‘the disappeared’) have been affected. The material is introduced by Index on Censorship's researcher on Latin America, Malcolm Coad.

Significance National GDP nevertheless contracted by just 1.5% in 2020 -- less than almost any other country in Latin America. Resilient remittances and exports, coupled with unprecedented policy support, have mitigated the effects of the pandemic and subsequent containment measures, leaving the country better placed for recovery than its neighbours. Impacts Enduring poverty, inequality and violent crime, and the impacts of accelerating climate change, will drive further migration from Guatemala. The government will pursue banking law reforms, to reduce risks to financial activities in the post-pandemic business environment. Infighting and corruption scandals will hinder the opposition's ability to benefit from the decline of the president's popularity.

This article provides an overview of some prominent aspects of intellectual history as practiced today in Latin America, especially regarding conceptual history. It delves into the way this methodology arrived to the region not long ago and discusses the way some of its practitioners combine it with the history of political languages, often ignoring the profound differences between both approaches. Therefore, the text stresses some of the most significant contrasts between them. In its last part, the article is critical of the purported “globality” of global intellectual history, an issue that is inextricably linked with the pervasive use of the English language in the field. Throughout, the text poses several of the challenges that lie ahead for intellectual history in Latin America.

Market multiples are more often used than studied. Equity analysts, investment bankers and other practitioners widely use market multiples to estimate the value of companies. Nevertheless, literature about multiples is not as rich as the wide use of these valuation tools would suggest. This paper, focusing on European listed companies, investigates how multiples can be used in the valuation of cyclical companies, a much less investigated research topic. We test the accuracy of multiples to understand whether their performance in valuing cyclical companies is better, worse or equal to the performance found in prior studies, where both cyclical and non cyclical companies are analyzed without distinguishing between them. We also attempt to verify whether the way in which multiples are calculated significantly affects the accuracy of estimation. Our aim is to develop a valuation approach consistent with valuation theory and helpful in everyday practice.

The notion of silence must be handled very carefully. In addition, its use reveals the way we deal with the urban environment as well as social life. What does the notion of silence convey about the current state of the urban sonic environment? How can we clarify the various meanings and the stakes involved in silence? Three themes are developed in order to answer these questions: silence as a research topic presents three complementary perspectives (acoustic, sociocultural, technological); silence as a polysemous notion emphasises the ideas of keeping quiet, tranquillity and pause; silence as a design issue relies on basic properties and principles in order to orient the design of the urban sonic environment.

One of the constant worries of the United States, since the role of a dominant world-power has been thrust on her, is the situation of Latin America. Relations with Canada require thought and preoccupation but they produce no deep concern. Canada and the United States understand each other and they form their policies in terms of friendly adjustment. Yet the same is not true when we consider the bloc of nations stretching to the south of the Rio Grande. They form two thirds of the geographic stretch of the western hemisphere, and they constitute a population equal to ours. The dependence on Latin America on the part of the United States in her capacity as an international power is evident. What is not evident is the way to make our friendship with our southern neighbors a more stable thing than the fragile arrangement which confronts us in the present.

AbstractScholars interested in labour in Latin America have traditionally paid little attention to trade unions’ legal mobilisation. However, the increasing number of legal complaints filed by workers with labour ministries and/or the courts in countries like Argentina, Brazil and Chile calls for a more serious debate on the role that trade unions play in this process. This article focuses on the Chilean case. Drawing on various sources, it shows that Chilean unions have turned legal complaints into a weapon to gain more rights and curb employers’ power. This process has involved the strongest and most combative unions, and is due to two historical conditions: (1) the obstacles placed in the way of successful resort to more disruptive tactics; (2) the increase in institutional opportunities to report infringements of the law. Overall, the article challenges the current image of the Chilean unions by foregrounding their agency and their achievements over the last decade.

Leaf Cutting

The breeding structure of both colony and population of social insects can be examined by genetic analysis. Colonies of the leaf-cutting ants Acromyrmex heyeri and A. striatus (Myrmicinae, Attini) were thus analyzed for isoenzyme systems MDH, a-GPDH, and AMY to describe genotype variability and social structure. A total of five loci were investigated (three for amylase and one for each other system). Ninety-seven colonies of A. heyeri and 103 of A. striatus were sampled in different localities in Southern Brazil (State of Rio Grande do Sul). The genotypes found show the occurrence of monogyny and polygyny associated or not with polyandry, which indicates that the social organization is colony-specific. The polygyny and polyandry observed are likely to be responsible for the great genotypic diversity of the colonies. The average inbreeding coefficient per colony was higher in A. striatus than in A. heyeri, which may reflect the different patterns of production of sexual individuals and nuptial flight of those two species.
