The fire ant Soleopsis invicta recently invaded Puerto Rico. Its presence has created great alarm among farmers and the public. This work reviews the ecology of this ant in the United States, Brazil and Puerto Rico in order to clarify some misconceptions. Information is provided to separate Solenopsis invicta from S. geminata. Colony foundation, caste differentiation, venom toxicity, and damage to agricultural crops and wildlife are discussed. The evidence supporting the damaging capabilities and ways to control this fire ant are examined.

Fire ants (Solenopsis richteri and Solenopsis invicta) have received scant attention from individuals other than agriculturists, entomologists, and victims of the bite and sting. Since their original importation into Mobile, Alabama, these small, seemingly benign, creatures have slowly migrated throughout most of the southern United States. Not unexpectedly, physicians working in the southern portions of the United States have been confronted with increasingly large numbers of patients, particularly children, who have been bitten and envenomated by these insects. Information regarding the pathogenesis of fire ant bite reactions and an approach to treatment are provided.

El artículo analiza la diplomacia pública del gobierno de Lázaro Cárdenas centrándose en su opción por publicitar la pobreza nacional en el extranjero, especialmente en Estados Unidos. Se plantea que se trató de una estrategia inédita, que accedió a poner en riesgo el “prestigio nacional” con el fin de justificar ante la opinión pública estadounidense la necesidad de implementar las reformas contenidas en el Plan Sexenal. Aprovechando la inusual empatía hacia los pobres en tiempos del New Deal, se construyó una imagen específica de pobreza que fuera higiénica y redimible. Ésta, sin embargo, no generó consenso entre los mexicanos. This article analyzes the public diplomacy of the government of Lázaro Cárdenas, focusing on the administration’s decision to publicize the nation’s poverty internationally, especially in the United States. This study suggests that this was an unprecedented strategy, putting “national prestige” at risk in order to explain the importance of implementing the reforms contained in the Six Year Plan, in the face of public opinion in the United States. Taking advantage of the increased empathy felt towards the poor during the New Deal, a specific image of hygienic and redeemable poverty was constructed. However, this strategy did not generate agreement among Mexicans.

2018 marks the 100th anniversary of the proclamation of Ukrainian independence. OnJanuary 22, 1918, the Ukrainian People’s Republic proclaimed its independence by adopting the IV Universal of the Ukrainian Central Rada, although this significant event was «wiped out» from the public consciousness on the territory of Ukraine during the years of the Soviet totalitarian regime. At the same time, January 22 was a crucial event for the Ukrainian diaspora in the USA. This article examines how American Ukrainians interacted with the USA Government institutions regarding the celebration and recognition of the Ukrainian Independence day on January 22. The attention is focused on the activities of ethnic Ukrainians in the United States, directed at the organization of the special celebration of the Ukrainian Independence anniversaries in the US Congress and cities. Drawing from the diaspora press and Congressional Records, this article argues that many members of Congress participated in the observed celebration and expressed kind feelings to the Ukrainian people, recognised their fight for freedom, during the House of Representatives and Senate sessions. Several Congressmen submitted the resolutions in the US Congress urging the President of United States to designate January 22 as «Ukrainian lndependence Day». January 22 was proclaimed Ukrainian Day by the governors of fifteen States and mayors of many cities. Keywords: January 22, Ukrainian independence day, Ukrainian diaspora, USA, interaction, Congress
