Os Ichneumonidae (Hymenoptera) da Estação Ecológica da Universidade Federal de Minas Gerais, Belo Horizonte, com ênfase nas espécies de Pimplinae

The Ichneumonidae (Hymenoptera) of the Estação Ecológica of the Universidade Federal de Minas Gerais, Belo Horizonte, with emphasis on the Pimplinae species. In one annual cycle 83,712 insects were captured, of which 2,339 were Ichneumonidae, belonging to 17 subfamilies; they were collected by a Malaise trap placed in a montane semidecidual seasonal forest, inside the campus. Among the collected ichneumonids there were 13 genera and 30 species of Pimplinae, of which Pimpla croceiventris was the most frequent species. The species richness of Pimplinae was greater in the ecological station in Belo Horizonte, MG than in other localities studied.

Isolamento e Caracterização Fenotípica e Molecular de Parasitos Leishmania sp. de Pacientes com Leishmaniose Tegumentar Americana (LTA) Atendidos no Hospital Universitário Lauro Wanderley da Universidade Federal da Paraíba

As leishmanioses são um complexo de doenças infecto-parasitárias endêmicas em 88 países que constituem um grave problema de saúde pública. Diversas espécies do gênero Leishmania são os agentes causadores da doença, dentre elas a espécie L. (V.) braziliensis associada a diferentes quadros clínicos da Leishmaniose Tegumentar Americana. No presente trabalho foram obtidos nove isolados de Leishmania sp. oriundos de LTA, sendo sete isolados (87%) oriundos de pacientes residentes no município de Pilões, um (13%) da cidade de João Pessoa, ambas regiões, do estado da Paraíba. Todos os nove isolados foram identificados como sendo da espécie L. (V.) braziliensis através de PCR específica. As análises de caracterização molecular pela técnica de RAPD-PCR mostraram que esses isolados compartilharam 62,63% revelando diferenças genotípicas entre elas. Contudo, os isolados AF e JSL, ambos provenientes de lesões disseminadas, tiveram o maior percentual de bandas compartilhadas dentre os isolados. Outra técnica molecular utilizada foi o SSR-PCR com o iniciador K7 que também foi capaz de demontrar polimorfismo entre os isolados. Nas análises de PCR-RLFP das regiões ITS1, foram encontradas perfis diferentes entre os isolados, onde MRSS, JMTS, AF, JCTS, JRL apresentaram o mesmo perfil de bandas e os isolados JSL, JCNS, MFTS e JAS tiveram, cada um, perfis de bandas distintos. Na análise de PCR-RLFP da região do gene hsp70, JSL, AF, JCTS, JRL, MFTS apresentaram o mesmo perfil de bandas e os isolados, MRSS, JMTS, JCNS e JAS perfis de bandas distintos. Adicionalmente foram também observadas diferenças fenotípicas entre estes isolados, visto que em dado momento de cultivo, todos apresentaram comportamento diferenciado, além de demonstrarem diferenças quanto à sensibilidade às drogas utilizadas na terapêutica das leishmanioses. Portanto estes estudos revelam que os isolados de L. (V.) braziliensis obtidos no estado da Paraíba demonstraram um significativo polimorfismo genético, revelando um alto nível de variação intraespecífica.

As borboletas (Lepidoptera, Papilionoidea) do Distrito Federal, Brasil

Neste estudo é apresentada uma listagem atualizada com 504 espécies e 506 subespécies de borboletas (Papilionoidea) observadas no Distrito Federal nas últimas quatro décadas, onde foram reunidos dados da bibliografia, de coletas pessoais e de várias coleções entomológicas; espécies com ocorrência apenas presumida não foram incluídas. Alguns aspectos relacionados à ocorrência de espécies ameaçadas e à conservação da fauna de borboletas no Distrito Federal são também discutidos.

Restless bandits, partial conservation laws and indexability

We show that if performance measures in a stochastic scheduling problem satisfy a set of so-called partial conservation laws (PCL), which extend previously studied generalized conservation laws (GCL), then the problem is solved optimally by a priority-index policy for an appropriate range of linear performance objectives, where the optimal indices are computed by a one-pass adaptive-greedy algorithm, based on Klimov's. We further apply this framework to investigate the indexability property of restless bandits introduced by Whittle, obtaining the following results: (1) we identify a class of restless bandits (PCL-indexable) which are indexable; membership in this class is tested through a single run of the adaptive-greedy algorithm, which also computes the Whittle indices when the test is positive; this provides a tractable sufficient condition for indexability; (2) we further indentify the class of GCL-indexable bandits, which includes classical bandits, having the property that they are indexable under any linear reward objective. The analysis is based on the so-called achievable region method, as the results follow fromnew linear programming formulations for the problems investigated.

The effect of divorce laws on divorce rates in Europe

This paper analyzes a panel of 18 European countries spanning from 1950 to 2003 toexamine the extent to which the legal reforms leading to easier divorce that took placeduring the second half of the 20th century have contributed to the increase in divorce rates across Europe. We use a quasi-experimental set-up and exploit the different timing of the reforms in divorce laws across countries. We account for unobserved country-specificfactors by introducing country fixed effects, and we include country-specific trends tocontrol for time-varying factors at the country level that may be correlated with divorcerates and divorce laws, such as changing social norms or slow moving demographictrends. We find that the reforms were followed by significant increases in divorce rates.Overall, we estimate that the introduction of no-fault, unilateral divorce increased thedivorce rate by about 1, a sizeable effect given the average rate of 4.2 divorces per 1,000married people in 2002.

Interest rate restrictions in a natural experiment: loan allocation and the change in the usury laws in 1714

This article studies the effects of interest rate restrictions on loan allocation. The British governmenttightened the usury laws in 1714, reducing the maximum permissible interest rate from 6% to5%. A sample of individual loan transactions reveals that average loan size and minimum loan sizeincreased strongly, while access to credit worsened for those with little social capital. Collateralisedcredits, which had accounted for a declining share of total lending, returned to their former role ofprominence. Our results suggest that the usury laws distorted credit markets significantly; we findno evidence that they offered a form of Pareto-improving social insurance.

Tobin meets Oates: Solidarity and the optimal fiscal federal structure

We explore the implications for the optimal degree of fiscal decentralization when people spreferences for goods and services, which classic treatments of fiscal federalism (Oates, 1972)place in the purview of local governments, exhibit specific egalitarianism (Tobin, 1970), orsolidarity. We find that a system in which the central government provides a common minimumlevel of the publicly provided good, and local governments are allowed to use their ownresources to provide an even higher local level, performs better from an efficiency perspectiverelative to all other systems analyzed for a relevant range of preferences over solidarity.
