Species of the oxyurum group (sensu Lauck) consist of five extant Neotropical small species, whose lengths range 15.0 to 20.0 mm. The anterior interocular width about 1.5 times the width of an eye and ventral diverticulum of phallus flattened, circular, and large are, in combination, diagnostic. The small species of the oxyurum group were included in the Lauck´s key to the identification of the species groups, without dealing with the species included in it because many of them are very similar in appearance. Therefore here we redescribe and key the Belostoma species of the oxyurum group. Belostoma oxyurum (Dufour) is newly recorded from Brazil (Paraná and Rio Grande do Sul). Holotype and lectotype are designated for B. oxyurum and B. sanctulum Montandon, respectively. The aspect of the prosternal keel, the ratio between the width of the ventral diverticulum of phallus and its length in ventral view, and the aspect of dorsal arms of ventral diverticulum have proven useful for better species delimitation. Based on specimens from Pará State (N. Brazil), Belostoma carajaensis Ribeiro & Estévez, sp. nov. is described and illustrated. This new species differs from B. sanctulum in having anteoculus shorter than interoculus and the dorsal arms of ventral diverticulum divergent and large. A male specimen of B. noualhieri Montandon was collected in São Paulo State and based mainly on features of male genitalia, this species is here also included under oxyurum group.

First report and morphological redescription of Teleonemia morio (Stål) (Hemiptera, Tingidae) in Annona squamosa L. (Annonaceae) in Brazil. This is the first report of a severe attack of Teleonemia morio (Stål, 1855) (Hemiptera, Heteroptera, Tingidae) on Annona squamosa L. (custard apple), causing up to 80% of losses of infested trees. In order to facilitate the identification of this insect pest, the adult female of T. morio is redescribed based on specimens collected in Palmeira dos Índios, Alagoas, Brazil.

Does the aggressiveness of the prey modify the attack behavior of the predator Supputius cincticeps (Stål) (Hemiptera, Pentatomidae)? The stink bug Supputius cincticeps (Stål) (Hemiptera, Pentatomidae) is a predator found in several Brazilian regions, which possesses desirable attributes as a natural control agent and in biological control programs. The aim of this study was to test if the attack behavior and predation success of S. cincticeps were affected by prey species. Larvae of Tenebrio molitor (L.) (Coleoptera, Tenebrionidae), Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae), and Thyrinteina arnobia (Stoll) (Lepidoptera, Geometridae) were offered to S. cincticeps in laboratory bioassays where predatory attack and prey defensive behaviors were observed for 2-hour periods. The attack behavior of S. cincticeps changed with the prey species offered. More than 25% of T. molitor and S. frugiperda larvae were immediately attacked, but T. arnobia was not immediately attacked by S. cincticeps. Successful attack (i.e., successful insertion of the predator stylets into the prey) depends on the region of the body attacked, with a greater proportion of successful attacks in the anterior than in the median or posterior regions. Larvae of T. arnobia and S. frugiperda displayed a sequence of abrupt head and body movements in response to S. cincticeps attack. Attempts of predation were more successful on T. molitor and S. frugiperda than on T. arnobia. Information about the differential attack behavior of S. cincticeps on different prey species is important for designing successful biological control programs using this hemipteran predator.

Os sistemas de informação sempre fizeram parte da gestão empresarial, quer fossem sistemas de arquivos ou sistemas informatizados. Porém, a aposta actual das empresas são os sistemas informatizados e de preferência, aqueles que integram e gerem numa mesma plataforma tecnológica todas as informações da empresa, independentemente do nível de gestão ou departamento, são os ditos sistemas ERP. Neste cenário, propusemos com este trabalho, realizar um estudo exploratório dos principais aspectos ligados aos sistemas ERP, como funcionamento, estruturação, implementação, benefícios e problemas. Os sistemas ERP (Enterprise Resource Planning) são sistemas cuja utilização expandiu na década de noventa, devido a um leque de factores, como bug do milénio, problemas de redundância e inconsistência dos dados armazenados e problemas originados pelo uso de sistemas isolados. As principais características desses sistemas podem ser resumidas da seguinte forma: sistemas modular, comercializadas e destinadas a integrar todos os dados da empresa numa única plataforma. Actualmente, existem no mercado mundial vários sistemas ERP, sendo que um deles é a PHC, objecto do nosso estudo de caso. O ERP PHC é produzido em Portugal, mas já é uma realidade no mercado cabo-verdiano. O supermercado Palácio Fenícia é um dos testemunhos de uso do sistema ERP PHC em Cabo Verde. Para clarificar o funcionamento dos sistemas ERP na gestão empresarial, propusemos com este trabalho estudar o funcionamento do ERP PHC no Supermercado Palácio Fenícia, pois conhecendo o funcionamento de um sistema ERP específico, fica-se a entender a lógica geral de qualquer ERP.

Egg parasitoids of Edessa meditabunda (Fabricius) (Pentatomidae) in lettuce crop. This study evaluated the occurrence of parasitoids in eggs of the stink bug, Edessa meditabunda (Fabricius, 1794) (Heteroptera, Pentatomidae) found on lettuce crop in Mato Grosso State, Brazil. Samples were collected in the vegetable garden "Cheiro Verde", in the municipality of Tangará da Serra, in curly lettuce. A bed of lettuce was selected randomly, where the eggs of E. meditabunda were collected. Five-hundred and seventy eight eggs of E. meditabunda were collected, 86.3% of them parasitized by Telenomus podisi Ashmead, 1893 (Hymenoptera, Platygastridae), Trissolcus urichi Crawford, 1913 (Hymenoptera, Platygastridae) and Neorileya albipes Girault, 1913 (Hymenoptera, Eurytomidae), representing respectively 57.0%, 38.2% and 4.8% of the emerged individuals. This is the first record of these three species parasitizing eggs of E. meditabunda in lettuce.

No impact of Bt soybean that express Cry1Ac protein on biological traits of Euschistus heros (Hemiptera, Pentatomidae) and its egg parasitoid Telenomus podisi (Hymenoptera, Platygastridae). Biological traits of the stink bug Euschistus heros and its main biological control agent Telenomus podisi were evaluated under controlled environmental conditions (25 ± 2ºC; 60 ± 10% RH; and 14/10 h photoperiod) by placing first instar nymphs into Petri dishes with pods originating from two soybean isolines (Bt-soybean MON 87701 × MON 89788, which expresses the Cry1Ac protein, and its near non-Bt isoline A5547) where they remained until the adult stage. Due to gregarious behavior exhibited by first instar nymphs, they were individualized only when at the second instar. Adults were separated by sex and weighed, and pronotum width of each individual was subsequently measured. They were placed into plastic boxes containing soybean grains of the same soybean isoline as food source. Egg viability and female fecundity were assessed in adult individuals. Adult females of T. podisi (up to 24h old) were placed with eggs of E. heros from mothers reared on both soybean isolines. Nymphal development time, insect weight, pronotum width, sex ratio, female fecundity, and egg viability (% emergence) of Euschistus heros did not differ between treatments. Eggto-adult development time, female longevity, sex ratio, and percentage of parasitized eggs were not impacted by the Bt-soybean (expressing Cry1Ac protein). Results indicate that the Bt-soybean, MON 87701 × MON 89788, has no direct significant impact on the two studied species.

This article examines the shoreline evolution and human occupation in the vicinity of the important archeological site of Amarynthos (Euboea Island, Greece) over the last six millennia. Archeological evidence indicates a continuous occupation of the site from the Bronze Age to the Roman period and the site is well-known, thanks to the existence of a sanctuary dedicated to the goddess Artemis. Based on the study of four boreholes, a paleogeographic reconstruction of the coastal landscape is proposed. Facies were determined based on mollusc identification, and sedimentology based on grain-size measurements (hand sieving for the fraction above 2 mm and LASER technique for particles below 2 mm) and loss-on-ignition. In addition, a series of 12 AMS radiocarbon dates define a reliable chronostratigraphy. Results suggest the presence of a fully marine environment from the early Holocene to ca. 2600-2400 cal. BC, which developed into a brackish environment from ca. 2600-2400 cal. BC to ca. 750 cal. BC due to the deltaic progradation of the nearby stream (Sarandapotamos River). From ca. 750 cal. BC onward, coastal swamps prevailed in the study area. Human-environmental interaction is discussed and particular attention is paid to the paleolandscape configuration of Amarynthos.

S'ha portat a terme una analisi estadística de les dades craniometriques de les principals poblacions catalano-balears del passat, des de J'Edat del Bronze fins a l'Edat Mitjana, i posteriorment s'han integrat les poblacions en un context peninsular més ampli. S'han analitzalles relacions entre poblacions per mitja d'un analisi d'agrupament (cluster), emprant els algoritmes UPGMA i del "veí més proper" i la distancia euclídea al quadrat. Així mateix, s'ha realitzat un re-mostreig (bootstrap) per comprovar la robustes de les agrupacions obtingudes i un test de Mantel per comprovar el grau de concordan~a entre les poblacions femenines i masculines. Els resultats mostren que, a nivell peninsular, els Bascos són la població més diferenciada de la resta des d'un punt de vista morfologic, la qual cosa pot estar relacionada amb una major antiguitat d'aquesta població, potser present des de temps pre-neolítics. La segona font de variació peninsular la constitueixen dues poblacions amb possibles influencies foranies d'origen africa: jueus i musulmans. La resta de poblacions, incloent-hi les de Mallorca, són notablement homogenies a pesar de la seva heterogene'itat cultural, temporal i geogràtfica. Finalment, es conclou que no hi ha cap analisi estadística que objectivament recolzi I'existencia deIs tipus racials tradicionalmcnt descrits a la Península Iberica, i que responen a una visió tipologica i estatica de la diversitat humana.

En un estudio osteológico de los restos humanos de la Edad del Bronce de Cataluña se ha puesto de manifiesto la existencia, en esta época, de un suave y gradual proceso de difusión racial a lo largo del litoral noroeste del Mediterráneo, así como las influencias que éste ha tenido en el área catalana, donde aparece un elemento foráneo, de origen centroeuropeo, minoritario, localizado fundamentalmente en Solsona y de modo particular en tres yacimientos muy cercanos entre sí: los megalitos de El Collet, Clara y la cueva sepulcral de AigüesVives (fig. 1). Este aporte foráneo, relacionado sin duda con las prospecciones de metal y objetos de origen transpirenaico como la cerámica de apéndice de botón, aparece asentado en la zona reutilizando los sepulcros y mezclado con la población indígena, según muestran las abundantes formas de tránsito (Turbón, 1977, págs. 132, 340, 418 Y 326).

Long-run economic growth arouses a great interest since it can shed light on the income-path of an economy and try to explain the large differences in income we observe across countries and over time. The neoclassical model has been followed by several endogenous growth models which, contrarily to the former, seem to predict that economies with similar preferences and technological level, do not necessarily tend to converge to similar per capita income levels. This paper attempts to show a possible mechanismthrough which macroeconomic disequilibria and inefficiencies, represented by budget deficits, may hinder human capital accumulation and therefore economic growth. Using a mixed education system, deficit is characterized as a bug agent which may end up sharply reducing the resources devoted to education and training. The paper goes a step further from the literature on deficit by introducing a rich dynamic analysis of the effects of a deficit reduction on different economic aspects.Following a simple growth model and allowing for slight changes in the law of human capital accumulation, we reach a point where deficit might sharply reduce human capital accumulation. On the other hand, a deficit reduction carried on for a long time, taking that reduction as a more efficient management of the economy, may prove useful in inducing endogenous growth. Empirical evidence for a sample of countries seems to support the theoretical assumptions in the model: (1) evidence on an inverse relationship betweendeficit and human capital accumulation, (2) presence of a strongly negative associationbetween the quantity of deficit in the economy and the rate of growth. They may prove a certain role for budget deficit in economic growth
