Polygyra cereolus (Megerle von Mühlfeld, 1816) is a small air-breathing snail originating in Florida, which is considered as an invasive species and is reported from a wide area in the south of the United States to Mexico and in some in some Caribbean Islands, Hawaii, Spain and the Arabian peninsula. Here we report the observation of this species in Puerto Rico.

Abstract Urochloa reptans is an annual grass regarded as native to Asia, the Arabian Peninsula, Australia and the Pacific region, although its status is ambiguous in many countries. The species grows forming clumps of slender, creeping culms up to 50 cm tall that are capable of displacing other plants and grasses. It is considered an important weed in agricultural lands and pastures, but it can also invade disturbed sites, degraded forests, coastal areas, river and creek beds, and riparian forests. Currently, it is listed as invasive in Costa Rica, Puerto Rico, the United States Virgin Islands and some islands in Oceania, where it has been reported invading relatively undisturbed forests.

This work analyses the diplomatic conflicts that slavery and the problem of runaway slaves provoked in relations between Mexico and the United States from 1821 to 1857. Slavery became a source of conflict after the colonization of Texas. Later, after the US-Mexico War, slaves ran away into Mexican territory, and therefore slaveholders and politicians in Texas wanted a treaty of extradition that included a stipulation for the return of fugitives. This article contests recent historiography that considers the South (as a region) and southern politicians as strongly influential in the design of foreign policy, putting into question the actual power not only of the South but also of the United States as a whole. The problem of slavery divided the United States and rendered the pursuit of a proslavery foreign policy increasingly difficult. In addition, the South never acted as a unified bloc; there were considerable differences between the upper South and the lower South. These differences are noticeable in the fact that southerners in Congress never sought with enough energy a treaty of extradition with Mexico. The article also argues that Mexico found the necessary leeway to defend its own interests, even with the stark differential of wealth and resources existing between the two countries. El presente trabajo analiza los conflictos diplomáticos entre México y Estados Unidos que fueron provocados por la esclavitud y el problema de los esclavos fugitivos entre 1821 y 1857. La esclavitud se convirtió en fuente de conflicto tras la colonización de Texas. Más tarde, después de la guerra Mexico-Estados Unidos, algunos esclavos se fugaron al territorio mexicano y por lo tanto dueños y políticos solicitaron un tratado de extradición que incluyera una estipulación para el retorno de los fugitivos. Este artículo disputa la idea de la historiografía reciente que considera al Sur (en cuanto región), así como a los políticos sureños, como grandes influencias en el diseño de la política exterior, y pone en tela de juicio el verdadero poder no sólo del Sur sino de Estados Unidos en su conjunto. El problema de la esclavitud dividió a Estados Unidos y dificultó cada vez más el impulso de una política exterior que favoreciera la esclavitud. Además, el Sur jamás operó como unidad: había diferencias marcadas entre el Alto Sur y el Bajo Sur. Estas diferencias se observan en el hecho de que los sureños en el Congreso jamás se esforzaron en buscar con suficiente energía un tratado de extradición con México. El artículo también sostiene que México halló el margen de maniobra necesario para defender sus propios intereses, pese a los fuertes contrastes de riqueza y recursos entre los dos países.

On 2 April 1917, President Woodrow Wilson urged Congress to enter the European war, and Congress voted to do so on Friday, 6 April. On the 15th of that month, Victor released the Original Dixieland Jazz Band’s record of “Livery Stable Blues” and “Dixieland Jass Band One-Step”; it caused an immediate nationwide sensation. James Reese Europe travelled to Puerto Rico in search of woodwind players for the Fifteenth New York Regiment Band, and the Creole Band ended its vaudeville career when it missed the train to Portland, Maine. German musicians in the United States came under increased scrutiny in the weeks after the declaration of war, as the country prepared to adopt new laws and regulations for wartime.

Abstract Section 162 of the South African Companies Act 71 of 2008 empowers courts to declare directors delinquent and hence to disqualify them from office. This article compares the judicial disqualification of directors under this section with the equivalent provisions in the United Kingdom, Australia and the United States of America, which have all influenced the South African act. The article compares the classes of persons who have locus standi to apply to court to disqualify a director from holding office, as well as the grounds for the judicial disqualification of a director, the duration of the disqualification, the application of a prescription period and the discretion conferred on courts to disqualify directors from office. It contends that, in empowering courts to disqualify directors from holding office, section 162 of the South African Companies Act goes too far in certain respects.

Racial Lines

It has become common to compare racial inequality in the United States with a “Latin American” pattern of racial inequality in which egalitarian racial ideologies mask stark socioeconomic inequalities along racial lines. However, relatively few comparative studies exist attempting to analyze variations in degrees of racial inequality in the Americas. To stimulate further research in this area, the following study analyzes census data on racial inequality in unemployment rates, educational attainment, homeownership rates, and income in Brazil, Colombia, Cuba, Puerto Rico, and the United States. The results suggest that while Brazil is similar to the United States in displaying large levels of racial inequality in the areas measured, Cuba and Puerto Rico display significantly lower levels of racial inequality and Colombia falls in between, undermining conceptions of a monolithic Latin American racial system.

AbstractExtensive collections of synanthropic fly parasitoids in animal excrement accumulations in the United States, Mexico, Costa Rica, Puerto Rico, Uruguay, Chile, Denmark, Israel, and South Africa yielded seven forms of a Muscidifurax complex which were totally or partially reproductively isolated. Morphological studies of female and male parasitoids coupled with biological and zoogeographical information permitted the identification of five sibling species. Muscidifurax raptor Girault and Sanders 1910 is redescribed and four additional species are described as new: M. zaraptor, from the southwestern United States; M. raptoroides from Central America and Mexico; M. uniraptor from Puerto Rico, and M. raptorellus from Uruguay and Chile. Biological notes are added to the descriptions, and it was postulated that the genus is undergoing a process of speciation with local populations slowly becoming reproductively isolated and eventually giving rise to morphologically distinguishable entities. Most evidence suggests the establishment of Muscidifurax in the New World, concomitant with or shortly following the establishment of muscoid flies in accumulated excrement. Scanning electronmicroscopy was used in the analysis of some morphological structures.

The first difference version of the restricted source-differentiated almost ideal demand system is used to estimate South Korean meat demand. The results of this study indicate that the United States has the most to gain from an increase in the size of the South Korean imported meat market in terms of its beef exports, while South Korea has the most to gain from this expansion in the pork market. Moreover, the results indicate that the United States has a competitive advantage to Australia in the South Korean beef market. Results of this study have implications for U.S. meat exports in this ever-changing policy environment.

A 5-month-old boy died of asphyxia from airway obstruction caused by his pacifier. It had been imported from Spain by La Cibeles Inc. of Union City, New Jersey, and had been marketed in New York, Massachusetts, New Jersey, Connecticut, Illinois, Maryland, Florida, and Puerto Rico under the brand names Fauna, Flower, Navy, and Texas. It sold for about 50 cents. It is attractive in design, but has characteristics that make it dangerous. Following our report to the United States Consumer Product Safety Commission,* the pacifier was recalled. We have been able to find only one similar case in the literature.1 The unnecessary tragedy was due to a preventable hazard and both individual and governmental action should avoid its recurrence.

Abstract The purpose of this research was to better understand the beliefs and practices that the residents of Puerto Rico have regarding cockfighting, including their perception of the recently passed prohibition against nonhuman animal fighting on the island. It had an exploratory descriptive design consisting of three phases, where the qualitative data obtained from phase one would guide the process of identifying variables that could be measured. In the second phase, an instrument was developed, and in the third, it was administered. Most of the participants agreed with the prohibition of cockfighting in Puerto Rico and that it was necessary. The data showed that there is a disconnect between what the federal government of the United States legislated, what the local government and agencies that were supposed to enforce the prohibition did with the legislation, and what the people directly affected by the legislation received for education and guidance.
