Proposta de arquitetura e protocolo para a geração automática de assinaturas de malwares

Given the exponential growth in the spread of the virus world wide web (Internet) and its increasing complexity, it is necessary to adopt more complex systems for the extraction of malware finger-prints (malware fingerprints - malicious software; is the name given to extracting unique information leading to identification of the virus, equivalent to humans, the fingerprint). The architecture and protocol proposed here aim to achieve more efficient fingerprints, using techniques that make a single fingerprint enough to compromise an entire group of viruses. This efficiency is given by the use of a hybrid approach of extracting fingerprints, taking into account the analysis of the code and the behavior of the sample, so called viruses. The main targets of this proposed system are Polymorphics and Metamorphics Malwares, given the difficulty in creating fingerprints that identify an entire family from these viruses. This difficulty is created by the use of techniques that have as their main objective compromise analysis by experts. The parameters chosen for the behavioral analysis are: File System; Records Windows; RAM Dump and API calls. As for the analysis of the code, the objective is to create, in binary virus, divisions in blocks, where it is possible to extract hashes. This technique considers the instruction there and its neighborhood, characterized as being accurate. In short, with this information is intended to predict and draw a profile of action of the virus and then create a fingerprint based on the degree of kinship between them (threshold), whose goal is to increase the ability to detect viruses that do not make part of the same family

Plantas entre los juruna: en busca de una metodología para el estudio del léxico

This paper presents methodological considerations related to the study of the plant lexicon of the Juruna ethnic group, an indigenous people of the Xingu Indigenous Park, Mato Grosso State, Brazil. The language of this ethnic group, along with that spoken by the Xipaya, belongs to the Juruna family of the Tupi stock. It is a tonal language with SOV syntactic structure (Fargetti 1992, 2007), and presents interesting processes of reduplication (Fargetti 1997). Part of our broader research project on the lexicology and lexicography of the language, research on the Juruna plant lexicon is still in development, together with studies of other semantic fields such as birds, material culture, and kinship relations. However, it is already possible to see interesting linguistic issues involving word formation, as well as issues of the relationship between language and culture (especially those related to “perspectivism”). These issues are presented in this paper.

Duby: uma perspectiva histórica sobre as mulheres medievais

This paper will discuss the wedding in the historical conditions of feudalism, and mainly, summarize partially the book Heloise and Isolde and other ladies of the twelfth century, in which the author provided an historical condition significant, exploring of an original manner the documents known. Then we will see as important medievalists have studied the issues addressed by Duby as kinship, sexuality, male and female, and that were the object of our work, serving as a counterpoint to them.

Heritability of Growth traits in fragmented popularions of Copaifera langsdorffii Desf. (Fabaceae)

The aim of this study is to investigate the genetic control of growth traits in the initial phases of development in fragmented populations of Copaifera langsdorffii Desf., using microsatellite markers. For the effect two populations of C. langsdorffii were used: a municipal park located in Sao Jose do Rio Preto (SJRP) and at Assis Ecological Station (AES), both in the state of sao Paulo, Brazil. The model to estimate the heritability coefficient is the method of regression of a measure of phenotypic similarity and an estimate of kinship between paired individuals. The coefficients of relatedness and heritability were estimated for three classes of distance (10, 20 and 30 m) within populations. Estimates of heritability were low (maximum 0.15) for all traits, ranging from positive values for regenerating individuals of the population SJRP and from negative to positive for the juvenile population AES. In evolutionary terms, these results indicate little chance of changing the population mean of the characters studied by natural selection; with strong random environmental effects changing this average. The results also suggest that the heritability for height to decrease between regenerating to juvenile stage and the natural selection in natural populations is stronger in the early stages of plant development.

Allonursing in river buffalo, Bubalus bubalis: Nepotism, incompetence, or thievery?

Allonursing was investigated in a dairy herd of 30 river buffalo cows and their calves. The primary behavioural variables were solicitations of allonursing by calves and acceptances of calves by cows. The sample of cows included a group of nine half-sisters, two additional pairs of half-sisters, and a pair of full-sisters. All of the calves were half-siblings owing to putative common paternity. Ancillary variables were age, milk-yield and docility of cows, as well as age, sex, weight and growth rate of calves. Three hundred and fifty-one instances of allonursing and 341 of filial nursing were recorded. There were large individual differences in the cows' tendencies to accept their own offspring and non-filial calves, and for the calves to successfully solicit milk from their mothers and other cows. Thirteen of the 30 cows accounted for 97% of the allonursing. Frequent allonursing was correlated with decreased growth rate in the donors' calves. Allonursing was unrelated to kinship or reciprocal relationships among the cows, and was associated with a lack of maternal experience in young cows and apparent milk theft by hungry calves whose mothers were not providing them with sufficient milk. © 1995 The Association for the Study of Animal Behaviour.

Rotinas familiares de crianças com necessidades especiais em família adotiva

Objetivou-se descrever as rotinas de três famílias, que adotaram crianças com necessidades especiais, que tinham conhecimento prévio dessa condição infantil. Utilizou-se o método de Estudo de Casos Múltiplos. Os dados foram obtidos por meio de Entrevista Semiestruturada (ES), do Inventário de Rotina (IR) e do Diário de Campo (DC). Quanto às semelhanças entre os grupos familiares, identificou-se que são comuns as atividades de alimentação/higiene, descanso e lazer, envolvendo a participação dos pais, irmãs e babás, geralmente nos ambientes domésticos da família. Observou-se diferenças importantes nos padrões de atividades, companhias e ambientes onde as rotinas ocorriam. Conclui-se que as variações nas rotinas estão relacionadas às particularidades de cada criança, à estrutura e nível socioeconômico de cada família participante.

Social cohesion among kin, gene flow without dispersal and the evolution of population genetic structure in the killer whale (Orcinus orca)

In social species, breeding system and gregarious behavior are key factors influencing the evolution of large-scale population genetic structure. The killer whale is a highly social apex predator showing genetic differentiation in sympatry between populations of foraging specialists (ecotypes), and low levels of genetic diversity overall. Our comparative assessments of kinship, parentage and dispersal reveal high levels of kinship within local populations and ongoing male-mediated gene flow among them, including among ecotypes that are maximally divergent within the mtDNA phylogeny. Dispersal from natal populations was rare, implying that gene flow occurs without dispersal, as a result of reproduction during temporary interactions. Discordance between nuclear and mitochondrial phylogenies was consistent with earlier studies suggesting a stochastic basis for the magnitude of mtDNA differentiation between matrilines. Taken together our results show how the killer whale breeding system, coupled with social, dispersal and foraging behaviour, contributes to the evolution of population genetic structure.
