In the present work the natural history and immature stages of Gonioterma exquisita Duckworth, 1964 of the Brazilian cerrado region are described. The caterpillars are external folivorous feeders and present a diet restricted to pubescent-leaved host plants of the genus Byrsonima Rich. (Malpighiaceae). They are solitary caterpillars and they build a hard individual shelter that looks like a planorbid shell, made from silk and frass, covered with trichomes and silk, where they develop until the last larval instar on the host plant, and remain inside it until the adult emergence on herbaceous stratum. The larval development presented eight instars. Egg, larval head capsules, instar duration, pupa, shelter, and behavior are also described. Diapause is mentioned for the first time in this species.

Age data frequently display excess frequencies at round or attractive ages, such as even numbers and multiples of five. This phenomenon of age heaping has been viewed as a problem in previous research, especially in demography and epidemiology. We see it as an opportunity and propose its use as a measure of human capital that can yield comparable estimates across a wide range of historical contexts. A simulation study yields methodological guidelines for measuring and interpreting differences in ageheaping, while analysis of contemporary and historical datasets demonstrates the existence of a robust correlation between age heaping and literacy at both the individual and aggregate level. To illustrate the method, we generate estimates of human capital in Europe over the very long run, which support the hypothesis of a major increase in human capital preceding the industrial revolution.

New records for species of Theope (Lepidoptera, Riodinidae) for the state of Pernambuco and northeastern Brazil, with notes on their natural history. Five new records for the state of Pernambuco and one new record for NE-Brazil are reported in this paper for the genus Theope. Relationship between ants and T. terambus was observed for the first time which also consists on the first ever recorded myrmecophilous interaction between Pheidole ants and a Theope immature. Schoepfia guianensis is reported as a probable hostplant for T. terambus. Illustrations of seven species of Theope which occur in the northeastern Atlantic Rainforest are provided.

Essays on the history of Brazilian dipterology. II. Notices about Brazilian Diptera (17th century). Notices from the Brazilian Diptera from the 17th century come mainly from two foreign invasions occurred in Brazil, the first one by the French in Maranhão and the second by the Dutch in northeastern Brazil. This paper includes reports of Fathers Claude d'Abbeville and Yves d'Evreux and from Piso and Marcgrave, the last two presenting the first illustrations of Brazilian Diptera. The paper also includes reports of Friar Laureano de la Cruz, Father João de Sotto Mayor and Maurício de Heriarte.

This paper registers reports about dipterans made by three Portuguese who lived in Brazil during the 18th century. Luiz Gomes Ferreira, in his book "Erário mineral" ["Mineral revenue"], wrote curious passages related with myiasis-causing flies of the genus Cochliomyia. José Rodrigues de Mello registered, in Latin verses, the folklore for curing myiases caused by Cochliomyia hominivorax in cattle. Luiz dos Santos Vilhena, in the last of his twenty letters dealing with several aspects of life in Brazil, made reference to horseflies, human bot flies and mosquitos.

According to Declan Kiberd, “postcolonial writing does not begin only when the occupier withdraws: rather it is initiated at that very moment when a native writer formulates a text committed to cultural resistance.” The Irish in Latin America – a continent emerging from indigenous cultures, colonisation, and migrations – may be regarded as colonised in Ireland and as colonisers in their new home. They are a counterexample to the standard pattern of identities in the major English-speaking destinations of the Irish Diaspora. Using literary sources, the press, correspondence, music, sports, and other cultural representations, in this thesis I search the attitudes and shared values signifying identities among the immigrants and their families. Their fragmentary and wide-ranging cultures provide a rich context to study the protean process of adaptation to, or rejection of, the new countries. Evolving from oppressed to oppressors, the Irish in Latin America swiftly became ingleses. Subsequently, in order to join the local middle classes they became vaqueros, llaneros, huasos, and gauchos so they could show signs of their effective integration to the native culture, as seen by the Latin American elites. Eventually, some Irish groups separated from the English mainstream culture and shaped their own community negotiating among Irishness, Englishness, and local identities in Brazil, Uruguay, Peru, Cuba, and other places in the region. These identities were not only unmoored in the emigrants’ minds but also manoeuvred by the political needs of community and religious leaders. After reviewing the major steps and patterns of Irish migration to Latin America, the thesis analyses texts from selected works, offers a version of how the settlers became Latin Americans or not, and elucidates the processes by which a new Irish-Latin American hybrid was created.

Catalogue of the type-specimens of Bolitophilidae, Diadocidiidae and Ditomyiidae (Diptera, Bibionomorpha) in the Natural History Museum, London. A commented list of the types of three families of Bibionomorpha - Bolitophilidae, Diadocidiidae and Ditomyiidae - housed at the Natural History Museum (London) is provided. This includes four holotypes and one paratype of five species of Bolitophilidae; one paratype and three syntypes of two species of Diadocidiidae; and 17 holotypes, 91 paratypes, four lectotypes, and fourteen paralectotypes of 38 species of Ditomyiidae. Lectotypes are designated for the Neotropical species of the ditomyiids Australosymmerus (Melosymmerus) bisetosus Edwards, 1940 and A. (M.) pediferus Edwards, 1940.

BACKGROUND: A history of diabetes is associated with an increased risk of several types of cancers. Whether diabetes is a risk factor for head and neck cancer (HNC) has received little attention. METHODS: We pooled data from 12 case-control studies including 6,448 cases and 13,747 controls, and estimated odds ratios (OR) and 95% confidence intervals (CI) for the associations between diabetes and HNC, adjusted for age, education level, sex, race/ethnicity, study center, cigarette smoking, alcohol use and body mass index (BMI). RESULTS: We observed a weak association between diabetes and the incidence of HNC overall (OR, 1.09; 95% CI, 0.95-1.24). However, we observed a modest association among never smokers (OR, 1.59; 95% CI, 1.22-2.07), and no association among ever smokers (OR, 0.96; 95% CI, 0.83-1.11); likelihood ratio test for interaction p=0.001. CONCLUSIONS: A history of diabetes was weakly associated with HNC overall, but we observed evidence of effect modification by smoking status, with a positive association among those who never smoked cigarettes. Impact: This study suggests that glucose metabolism abnormalities may be a HNC risk factor in subgroups of the population. Prospective studies incorporating biomarkers are needed to improve our understanding of the relationship between diabetes and HNC risk, possibly providing new strategies in the prevention of HNC.

Major bubble episodes are rare events. In this paper, we examine what factors might cause some asset price bubbles to become very large. We recreate, in a laboratory setting, some of the specific institutional features investors in the South Sea Company faced in 1720. Several factors have been proposed as potentially contributing to one of the greatest periods of asset overvaluation in history: an intricate debt-for-equity swap, deferred payment for these shares, and the possibility of default on the deferred payments. We consider which aspect might have had the most impact in creating the South Sea bubble. The results of the experiment suggest that the company?s attempt to exchange its shares for government debt was the single biggest contributor to the stock price explosion, because of the manner in which the swap affected fundamental value. Issuing new shares with only partial payments required, in conjunction with the debt-equity swap, also had a significant effect on the size of the bubble. Limited contract enforcement, on the other hand, does not appear to have contributed significantly.

ABSTRACT Elachista synethes was recently recognized as an alien species in northern Chile, where its larvae mine the rescue grass Bromus catharticus (Poaceae). In order to provide the necessary information to allow field detection of E. synethes during early ontogeny, we conducted a morphological reappraisal of the immature stages of this leaf-miner moth, based on light and scanning electron microscopy, including the first descriptions of the egg and the first-instar larva. This is the first report of the existence of an apodal early larva for a species of Elachista Treitschke. The legs and prolegs are absent in the first two instars, but are well developed in the last two. Additional observations on the life history are also provided, including a description of the mine.

Variation in coloration with a strong underlying genetic basis is frequently found within animal populations but little is known about its function. Covariation between colour polymorphism and life-history traits can arise because morphs perform differently among environments or because they possess alternative alleles coding for key life-history traits. To test these two hypotheses, we studied a population of tawny owls Strix aluco, a bird displaying red, brown and grey morphs. We assessed the colour morph of breeding females, swapped eggs or hatchlings between pairs of nests, and examined how body condition in 3-week-old nestlings covaries with coloration of foster and genetic mothers. Redder foster and genetic mothers produced young in better condition. Because in two other years we observed that greyish females produced offspring in better condition than those of red females, the present study suggests that colour polymorphism signals genetic and phenotypic adaptations to cope with a fluctuating environment.
