Network analysis as a tool for ecological interactions studies has been widely used since last decade. However, there are few studies on the factors that shape network patterns in communities. In this sense, we compared the topological properties of the interaction network between flower-visiting social wasps and plants in two distinct phytophysiognomies in a Brazilian savanna (Riparian Forest and Rocky Grassland). Results showed that the landscapes differed in species richness and composition, and also the interaction networks between wasps and plants (...) had different patterns. The network was more complex in the Riparian Forest, with a larger number of species and individuals and a greater amount of connections between them. The network specialization degree was more generalist in the Riparian Forest than in the Rocky Grassland. This result was corroborated by means of the nestedness index. In both networks was found asymmetry, with a large number of wasps per plant species. In general aspects, most wasps had low niche amplitude, visiting from one to three plant species. Our results suggest that differences in structural complexity of the environment directly influence the structure of the interaction network between flower-visiting social wasps and plants. (shrink)

Assessment of marine debris ingestion by sea turtles is important, especially to ensure their survival. From January to December 2011, 23 specimens of five species of sea turtleswere found dead or dying after being rehabilitated, along the coast of the municipality of Rio de Janeiro, Brazil. To detect the presence of marine debris in the digestive tract of these turtles, we conducted a postmortemexamination from the esophagus until the distal portion of the large intestine for each specimen. Of the total (...) number of turtles, 39% had ingested marine debris such as soft plastic, hard plastic, metal, polyethylene terephthalate (PET) bottle caps, human hair, tampons, and latex condoms. Five of the seven sea turtles species are found along the Brazilian coast, where they feed and breed. A large number of animals are exposed to various kinds of threats, including debris ingestion.

This research was done in Juiz de Fora, Minas Gerais, Brazil on february 2012, with objective was to determine which species of social wasps visiting mango fruits, their behaviors displayed by them while foraging and verify which the species of wasps visitors offer risk of accidents to farmers. The studied area was monitored during February 2012, from 8:00 to 17:00. in a 144 hour effort, and the data collected included the time of activity, diversity, aggressiveness and the general behavior of (...) social wasps around the fruits. There were registered a total of 175 individuals of 12 different species, healthy fruits were damaged during the day, and we registered the abundance and richness peaks throughout the day. This study indicated the needs for special care during the harvest, as aggressive wasps are indeed present and the abundant, resulting in a possible increase of the risk for the workers. (shrink)

Social wasps are broadly distributed in Brazil, and their distribution is closely related to local plant composition. However, only a few studies on the diversity of these insects have been carried out in northeastern Brazil, and in Caatinga Biome the diversity is probably underestimated due to the lack of inventories for the region. Aiming at advancing the knowledge about the wasp fauna, we carried out this study from October 2005 to September 2006 in Ibipeba, northeastern Brazil. We collected 172 wasps (...) of five genera and eight species, and recorded Polybia ruficeps Schrottky, 1902 for the first time in the state of Bahia. The most abundant species was Polybia ignobilis (Haliday, 1836) (n = 69), and the least abundant were Brachygastra lecheguana (Latreille, 1824) (n = 2) and Polistes canadensis (Linnaeus, 1758) (n = 2). The present study inventory focused exclusively on the diversity of social wasps in an area of Caatinga, which contributes to advance the local fauna knowledge. (shrink)

Generally, frugivorous lepidopteran, have great ecological importance and are often used as bioindicator in environmental assessment studies. However, the proposed methodologies for capturing moths require great effort on the field for installation and monitoring of traps, in addition to their high cost. Thereat attractive baits have been evaluated to assist the work of detection and monitoring of moths. The aim of this study was, therefore, to record the diversity of the Noctuidae family captured by traps with food attractions evaluate the (...) performance of this methodology model for its use in future work with cutworms. The study was conducted in urban semideciduous seasonal forest fragment in which three types of bait were used: pineapple with sugarcane juice, banana with sugarcane juice, and banana with water and collected 49 individuals of the Noctuidae family spread over six genera and eleven species. The bait of pineapple with sugarcane juice was the one with the highest diversity index, but the bait that showed greater wealth and greater dominance was banana with water as bait banana with sugarcane juice showed the highest equitability. From the results, it can be inferred that the use of attractive traps can be an advantageous alternative for Rapid Ecological Assessment or determining the presence of some groups as Noctuidae in a given area, explaining the need for the improvement of traps and bait tests to obtain best response of moths to this methodology.

This is the first record of nesting in the soil by the ant Camponotus sericeiventris (Guérin-Méneville, 1838), which has arboreal habit. The study was conducted in southeastern Brazil, in an ant colony located in a subterranean site. This study describes, for the first time, the ability of this arboreal species to vary its nesting site by the occupation of an unusual place in an urban environment; and this study demonstrates that this species is an interesting model for studies in urban (...) environments.

Solenopsis saevissima fire ants were found foraging in a Felis catus carcass over tissues an secretions present in holes and mucosa. The ants built a dirt-made physical structure around the carcass, which prevented necrophagous flies from laying eggs or larvae in the body. These observations are relevant to increasing knowledge on the role of this ant genus in the decaying process of other animal corpses, including humans.

The literature provides different methodologies for sampling social wasps, including, flight intercept trap type Malaise and Attractive trap, however, there is no consensus on its use. In this respect, the aim of this study was to evaluate the best use of Malaise traps and Attractive trap in biodiversity work of social wasps, and generate a collection protocol for the use of these traps. The study was conducted in the Parque Estadual do Rio Doce, located in the east of the state (...) of Minas Gerais, in the years 2000, 2001, 2002 and 2004 and in the Botanical Garden of the Federal University of Juiz de Fora, located in the southeastern state of Minas Gerais, in years 2011, 2012 and 2013. 15 species were collected using Malaise traps, and, 26 species of social wasps were collected using Attractive traps. Although the negative aspects of both traps, complementary methodologies surveys varying social wasps are useful and it is recommended to choose for using in accordance with the logistical field.

Previously unreported nesting associations of Yellow-Olive Flycatcher (Tolmomyias sulphurescens) (Aves: Tyrannidae) with social wasps and bees.

Protopolybia sedula is a social swarming wasp, widely spread throughout many countries in the Americas, including most of Brazil. Despite its distribution, studies of its behavioral ecology are scarce. This study aimed to describe its foraging activity and relation to climatic variables in the city of Juiz de Fora in southeastern Brazil. Three colonies were under observation between 07:00 and 18:00 during April 2012, January 2013, and March 2013. Every 30 minutes, the number of foragers leaving and returning to the (...) colony was registered along with air temperature and relative humidity. Activity began around 07:30¸ increased between 10:30 and 14:30, and ended around 18:30. A mean of 52.7 exits and 54 returns were measured every 30 minutes. The daily mean values were 1,107 ± 510.6 exits and 1,135 ± 854.8 returns. Only one colony showed a significant correlation between forager exits and temperature (rs = 0.8055; P < 0.0001) and between exits and relative humidity (rs = -0.7441; P = 0.0001). This paper shows that climatic variables are likely to have little control on the foraging rhythm of P. sedula when compared to other species, suggesting the interaction of other external and internal factors as stimuli of species foraging behavior.

Ophiocordyceps is a fungal pathogen of ants of the tribe Camponotini. It is called zombie fungus, since it changes the host behavior, causing them to die in an exposed position, typically clinging onto and biting into the adaxial surface of shrub leaves. This study aimed to describe the occurrence of parasitic associations between Ophiocordyceps and ants of the genus Camponotus in an urban fragment of Atlantic Rainforest in southeastern Brazil and to measure the rate of hyperparasitism in Ophiocordyceps by other (...) fungi in the same location. We found 57 individuals of four species of ants and three species of fungus. The age categories of fungi were equally distributed, and rate of hyperparasitism was 17.5% (n = 10). The sampled area was recognized as an important site of Ophiocordyceps occurrence. (shrink)

This record describes the occurrence of conflicts between stingless bees of an active colony of Scaptotrigona bipunctata (Lepeletier) and individuals of Melipona quadrifasciata (Lepeletier), and discusses possible hypotheses that motivated the attack. Behaviors were observed in an active colony of S. bipunctata. The active nest guards detained individuals of M. quadrifasciata who invaded the colony. The chances of misidentification of the colony entrance and error in the species possible aggregation were discarded, however, the hypothesis of the real invasion recorded in (...) this study demonstrates a behavioral strategy by M. quadrifasciata suggests that there is an energy savings if successful in looting.

No interior do pensamento de Dewey, a gênese da estética merece mais atenção do que lhe é dada na literatura. Um aspecto, em especial, tem sido virtualmente negligenciado — com as notáveis exceções de Robins 2015, Ueno 2016, Hein 2017 e Granger 2018a e 2018b — a saber, os vínculos com Albert Coombs Barnes. Nossa hipótese é que Barnes desempenhou um papel relevante na “virada estética” da filosofia madura de Dewey. Neste artigo, nós tomamos um primeiro passo rumo ao esclarecimento (...) da relação entre eles e uma tentativa de mostrar a influência do colecionador de arte na obra do filósofo. (shrink)

Ad oggi non esistono in letteratura studi specificatamente dedicati al collezionismo privato di antichità in Basilicata, al contrario di quanto avvenuto in altre regioni limitrofe del Meridione d’Italia. Eppure, ad un’attenta disamina delle fonti bibliografiche e archivistiche – queste ultime per lo più inedite – disponibili, appare evidente come questo territorio molto ricco sotto il profilo archeologico abbia in realtà conosciuto, tra il XVIII e gli inizi del XX secolo, numerose ed importanti esperienze collezionistiche a livello locale. Nel presente contributo (...) si cercherà per la prima volta non solo di enuclearne sistematicamente episodi e protagonisti principali, ma anche di delinearne alcune linee di tendenza generali e seguirne l’evoluzione di forme e contenuti nel corso del tempo. L’intento che si vuole perseguire, in altre parole, è quello di giungere ad una messa a fuoco della “cultura collezionistica” lucana, la quale pare perfettamente inserirsi e trovare ragion d’essere nella più ampia cultura antiquaria italiana e europea del periodo considerato, offrendo al contempo nuovi dati per la conoscenza di una delle sue espressioni più peculiari: la pratica di ricercare e raccogliere testimonianze materiali del passato al fine di elaborare nuove costruzioni identitarie nel presente.

O presente artigo tem como objetivo realizar uma leitura do modo como a biopolítica, em autores como Foucault e Agamben, reflete sobre a economia em sua constituição contemporânea, desde a sua formação moderna, numa ordem que é liberal e capitalista. Em um primeiro momento, busca-se apresentar uma contextualização, indicando a relação entre Mercado e Estado no mundo moderno, destacando alguns destes aspectos fundamentais. Em seguida, almeja-se refletir e expor a relação entre a biopolítica e economia, privilegiando aquilo que Foucault realizou (...) em Nascimento da Biopolítica e, logo depois, apresentar as percepções de Agamben sobre o capitalismo, destacando o livro O Reino e a Glória. Não se propondo uma reflexão fechada, busca-se apresentar as reflexões dos autores, marcada pela leitura biopolítica, sobre a hegemonia do econômico na contemporaneidade. (shrink)

An open question in the semantics of modality is what relations there are among different modal flavours. In this article, we consider the thorny issue of whether ascribing to an agent the obligation to φ implies that it is possible for the agent to φ. Traditionally, this issue has been interpreted as whether ‘ought’ implies ‘can’. But another linguistic interpretation is available as well, namely, whether ‘must’ implies ‘can’ (MIC). We show that ‘must’ does imply ‘can’ via a convergent argument. (...) The first strand of the argument is theoretical: it consists in proving MIC from a well-established theory of modality in natural language, i.e., that proposed by Kratzer. The second strand is empirical: we present novel acceptability judgment studies showing that MIC predicts and explains the linguistic behaviour of native English speakers. (shrink)

Esta pesquisa analisa as motivações de Heidegger para colocar em questão o sentido do ser,conforme seu projeto em _Ser e Tempo_, publicado em 1927, no qual analisa a metafísica tradicional e chega à conclusão de que a história da filosofia se deteve a refletir apenas sobre os entes, esquecendo-se do ser. No §6 de _Ser e Tempo_, Heidegger assume como tarefa a destruição da história da ontologia. Por isto, tece profundas críticas à categorização do ser na _Vorhandenheit_ grega – em (...) Platão e Aristóteles – e desarticula o racionalismo de René Descartes. Para os gregos, o ser consistia em uma essência previamente estabelecida, e caracterizava-se pela universalidade, infinitude e imutabilidade. Em Descartes, com a elaboração da _res cogitans _e _res extensa_, assujeitou-se o _Dasein_ e a dualidade entre sujeito e objeto foi fortificada. Heidegger, por seu turno, objetivou o desenvolvimento de uma filosofia que desarticulasse a metafísica proposta pela tradição (incluindo-se a corrente racionalista), e aludiu que o _Dasein_, isto é, o ente humano, pelo seu caráter ontológico, não possui essência prévia – é um ente existencial – e não é um sujeito dual – pois é um _ser-no-mundo_. Logo, não há, na natureza humana, elementos que caracterizam o ser do ente humano antes da sua existência propriamente dita, porque é apenas na existência e nos horizontes de temporalidade que o _Dasein_ se constitui e se percebe como ente aberto às possibilidades mundanas. A filosofia heideggeriana, neste sentido, pode ser relacionada com a educação, já que os diferentes saberes são construídos coletivamente, na relação ser-com (_mitsein_). Partindo da ontologia de Heidegger, a educação é uma ferramenta que possibilita o direcionamento do ser do estudante à autenticidade existencial. (shrink)

This article examines the comparison between a reductionist mechanistic paradigm and the Goethean paradigm, that provides a vision of an informed universe.

In business administration or in economics it is absolutely relevant not to consider indexes like profit growth rate or gross domestic product as exhaustive indexes for economic wealth. Likewise, in biology it is important not to confuse the representation of life with life itself. The most important concepts in biology are information, memory, structure, plasticity, and robustness. Information is the difference that makes the difference. Memories are information registered in an organism. Plasticity is the capacity of a living organism to (...) change its own structure/sets of behaviors for having a competitive advantage. Robustness is the ability of a living organism to resist environmental changes without changing its own structure/sets of behavior, and fragility is when a living organism undergoes changes in its own structure without being able to resist non-adaptive changes.

Ainda que a estética de John Dewey tenha sido assunto de uma grande quantidade de estudos conduzidos através de abordagens muito diferentes há uma ausência de contribuições capazes de reconhecer vínculos entre a estética de Dewey e a história da arte. Neste artigo, analisamos três obras de arte da Antiguidade tardia, principalmente, seguindo os conceitos-chave de Dewey de análise formal e desvio, para reconstruir a experiência estética do autor, o observador e o patrono de cada obra de arte. Nosso propósito (...) é duplo. Primeiro, queremos demonstrar que uma abordagem baseada na teoria de Dewey é frutífera quando se estuda obras de arte antigas. Segundo, queremos demonstrar que uma interpretação pragmatista da arte antiga tardia é mais frutífera e menos reducionista do que as tradicionais. (shrink)

We discuss the possible breakdown of Lorentz invariance—at distances greater than the Planck length—from both the theoretical and the phenomenological point of view. The theoretical tool to deal with such a problem is provided by a “deformation” of the Minkowski metric, with parameters dependent on the energy of the physical system considered. Such a deformed metric realizes, for any interaction, the “solidarity principle” between interactions and spacetime geometry (usually assumed for gravitation), according to which the peculiar features of every interaction (...) determine—locally—its own spacetinie structure. The generalized theory of relativity, based on the locally deformed Minkowski spacetime, is called “deformed special relativity” (DSR). In the first part of the paper, we give the foundations and the basic laws of DSR. In the second part, we analyze some experimental data, which admit an interpretation in terms of the DSR formalism and are, therefore, candidates for displaying a breakdown of the Lorentz symmetry. They are (i) the superluminal propagation of evanescent electromagnetic waves in waveguides, (ii) the meanlife of the KS 0, (iii) the Bose-Einstein correlation in pion production and (iv) the comparison of clock rates in the gravitational field of Earth. Such analysis provides us with the explicit forms of the related deformed metrics as functions of the energy, thus putting in evidence, in all four cases (and therefore for all four fundamental interactions), departures from the usual Minkowski metric. This preliminary evidence for a broken Lorentz invariance may be regarded as the signature of possible nonlocal effects involved in the processes examined. Moreover, the corresponding deformed metrics obtained by our analysis provide an effective dynamical description of the interactions (at least in the energy range considered). (shrink)

According Klemperer language thinks for us. But also the institutions think for us. With the result that the practices often determine a common thought that is shared and made their own without realizing it. What thought communicates the current organization of the teaching practice of the Italian schools? The report answers this question by showing how users should be aware of the precise meaning of these educational practices.

Die Autoren entwickeln das Konzept einer sich auf dem Weg von Mimesis kulturell stets neu formierenden Leiblichkeit. In ihrem Ansatz verbinden sie europäische Konzepte wie Merleau-Pontys Phänomenologie, kulturanthropologisch orientierte Erziehungstheorie und Foucault mit lateinamerikanischen Forschungen. Vor diesem Hintergrund wird ein kritischer Blick auf den brasilianischen Schönheitskult geworfen, der mittlerweile bereits im Kinderzimmer angekommen ist.

Contemporary Darwinian medicine is a still-expanding new discipline whose principal aim is to arrive at an evolutionary understanding of aspects of the body that leave it vulnerable to disease. Historically, there was a precedent; between 1880 and 1940 several scientists tried to develop a general evolutionary theory of disease as arising from deleterious traits that escape elimination by natural selection. In contrast, contemporary Darwinian medicine uses evolutionary theory to consider all the possible reasons why selection has left human vulnerable to (...) a disease. (shrink)

Fábio Alves dos Santos (1954-2013) cursou Pedagogia, Ciências Sociais e Teologia, era Especialista em Filosofia da Religião (PUC Minas), Advogado (PUC Minas) e Mestre em Direito Constitucional (UFMG). Lecionou na PUC Minas como professor de Cultura Religiosa e depois como professor no Curso de Direito, atuando principalmente no Serviço de Assistência Judiciária – SAJ, especialmente cuidado de causas populares como as da ASMARE (Associação dos Catadores de Papel, Papelão e Material Reaproveitável de Belo Horizonte), da Pastoral de Rua, da (...) Pastoral Carcerária, de movimentos de “Sem Casa”, de ocupações e tantos outros grupos. Fábio sofria de grave problema de visão há mais de 15 anos. Quase ficou cego depois de diversas cirurgias de miopia. Isso, porém, não o impedia de seguir seu constante compromisso com as lutas populares. Na última entrevista que concedeu, menos de um mês antes de sua morte (19 de outubro de 2013), depois de duro sofrimento de quase dois anos, no tratamento de um câncer no pâncreas, conta um pouco de sua vida, sua luta e sua percepção de várias realidades, especialmente da Igreja e da pastoral. Militante formado na Teologia da Libertação, de profunda espiritualidade, marcada por traços da religiosidade popular nordestina e comprometida com a libertação, Fábio Alves também buscou em sua vida abrir-se à teologia do pluralismo religioso, especialmente com o Santo Daime, em cuja tradição religiosa chegou a ser “fardado”, mantendo uma profunda atitude espiritual aberta ao diálogo inter-religioso. Sua primeira publicação foi “Começo de mundo novo: sofrimento, luta e vitória dos posseiros de Santana dos Frades”, Sergipe, numa versão popular em 1981 e outra pela Editora Vozes (1990). Fruto de sua dissertação de mestrado, publicou o livro “Direito Agrário: política fundiária no Brasil (1995). Em 2001 saiu seu último livro, uma coletânea de artigos publicados em diversos jornais: “Em defesa da vida”. Num artigo em Horizonte (2004), juntamente com o advogado, amigo e colega Prof. Cristiano de Melo Bastos, discutiu “A prática jurídica na missão da PUC Minas”.

Internal misconduct is a universal problem in prisons and affects the maintenance of social order. Consequently, correctional institutions often develop rehabilitation programs to reduce the likelihood of inmates committing internal offenses and criminal recidivism after release. Therefore, it is necessary to identify the profile of each offender, both for the appropriate indication of a rehabilitation program and the level of internal security to which he must be submitted. In this context, this work aims to discover the most significant characteristics in (...) predicting inmate misconduct from ML methods and the SHAP approach. A database produced in 2004 through the Survey of Inmates in State and Federal Correctional Facilities in the United States of America was used, which provides nationally representative data on prisoners from state and federal facilities. The predictive model based on Random Forest performed the best, thus, we applied the SHAP to it. Overall, the results showed that features related to victimization, type of crime committed, age and age at first arrest, history of association with criminal groups, education, and drug and alcohol use are most relevant in predicting internal misconduct. Thus, it is expected to contribute to the prior classification of an inmate on time, to use programs and practices that aim to improve the lives of offenders, their reintegration into society, and consequently, the reduction of criminal recidivism.
