Aspectos do cuidado cooperativo em dois grupos de Callithrix jacchus selvagens

The Callitrichidae family presents cooperative breeding, where breeders and non breeders take care of the offspring. The aspects of care analyzed in this study were infant carrying, supervision, proximity and food transfer. Three sets of infants from two wild groups of Callithrix jacchus were studied in the environments of Caatinga (Assu group) and Atlantic Forest (Jundiaí group). The methods used in the study were instantaneous focal sampling (infant carrying, supervision and proximity) and continuous focal sampling (food transfer). In the two sets observed in Assu group, the father carried and transferred food to infants more than the rest of the group. The biggest contribution in supervision was from the father and from another adult male. The members that remained in proximity to the infants in both groups were the younger in the groups (juveniles and sub-adults). In the Jundiaí group, the father and the adult male helper of the group were the main caregivers; one of the sub-adult females was responsible for supervision of the infants. With the disappearance of the reproductive male and one of the sub-adults females in 3º month of infants life, the care was redistributed and the only adult male left in the group was the animal that contributed more in provisioning of the infant. In the Assu group, there were adult females in its composition which were involved in agonistic interactions with breeders and adult males, and seemed to influence their low participation in care. Food transfer initiates early in the development of the infants, as a way to encourage nutritional independence. Different types of food transfer (active food transfer, food steal, food steal attempt, passive food transfer and food handling) were observed in the study and frequency of each one varied with developmental phase and tolerance by the members. One relevant data of the study was the presence of active food transfer in Assu group, since in literature there are very few registers of this type of transfer for this species. It is important that groups from distinct environments and composition be studied for a better understanding of the dynamics of infants development

Aplicabilidade do Rorshach na avaliação psicológica do autismo

This study investigates the applicability of the Rorschach Method for evaluating the personality of people with Autism Spectrum Disorder (ASD).The relevance of this study is justified by the limited number of investigations published in the research literature concerning the use of psychological tests used for evaluating the personality of individuals with ASD. The Rorschach Method was chosen as an appropriate instrument considering it reveals the personality s basic structure, including characteristics of the affectivity, sensuality, inner life, mental resources, psychic energy and general characteristics and intellectual state of the individual. The general objective of this investigation consisted of verifying the applicability of the use the Rorschach Method in the evaluation of the characteristics of people's personality with autism spectrum disorder (ASD).The study also sought to identify perceptive factors of the personality structure of individuals with ASD, provide contributions of the understanding of this syndrome, seeking the establishment of possible therapeutic interventions starting from diagnostic by Rorschach Method. In addition, this investigation aims at verifying the adequacy of using the Rorschach Method as an instrument for evaluating the personality characteristics of individuals with ASD and its possible use in Brazil, starting from preliminary normative results. Participants consisted of 44 youngsters and adults, both genders with age range 14 - 39 years-old (average: 23.5 years-old) distributed in 2 groups. Group 1: composed with 22 youngsters and adults with clinical diagnosis of autism spectrum disorder (communication impairments, social interaction deficits, restricted and repetitive interests and activities); Group 2: composed with 22 youngsters and adults with typical behavior. The participants were paired to gender and age, individually. The Mann-Whitney and Wilcoxon tests were applied to evaluate statistical differences between the groups, considering demographic and social data. The results indicate the presence of restricted interest or difficulty in the expression of the social and affective interaction of people with ASD. However, the need of broader normative studies concerning the use of personality evaluation instruments for people with ASD is warranted. These investigations could help understand the psychic dynamism of this population, offering subsidies that can be added to the current techniques of diagnosis. The Rorschach Method is susceptible to application but it is necessary to respect the individual limitations of these people and to establish more criterions about the spectrum

Caracterização de látices acrílicos em função da neutralização de seus grupos carboxilas

Latexes based on acrylic acid, acrylamide, ethyl methacrylate, and ethyl acrylate were synthesized via emulsion polymerization with different monomer compositions. The resultant latices were thickened with different molar ratios of NaOH to acrylic acid and were analyzed in terms of acid‐basis titrimetry, turbidimetry, rheology, and tensiometry. Titrimetry, turbidimetry, and rheometry were used to analyze factors such as carboxyl group availability and particle solubilization, tensiometry monitoring the influence of carboxyl neutralization on polymer‐surfactant interactions. For the acrylic acid content used in this work (20 wt%), the results indicated that as carboxyl groups distribution became more homogeneous, the process of latex thickening became more effective

GT4CCI: uma abordagem baseada em grounded theory para a identificação de interesses transversais em documentos de requisitos

When crosscutting concerns identification is performed from the beginning of development, on the activities involved in requirements engineering, there are many gains in terms of quality, cost and efficiency throughout the lifecycle of software development. This early identification supports the evolution of requirements, detects possible flaws in the requirements specification, improves traceability among requirements, provides better software modularity and prevents possible rework. However, despite these several advantages, the crosscutting concerns identification over requirements engineering faces several difficulties such as the lack of systematization and tools that support it. Furthermore, it is difficult to justify why some concerns are identified as crosscutting or not, since this identification is, most often, made without any methodology that systematizes and bases it. In this context, this paper proposes an approach based on Grounded Theory, called GT4CCI, for systematizing and basing the process of identifying crosscutting concerns in the initial stages of the software development process in the requirements document. Grounded Theory is a renowned methodology for qualitative analysis of data. Through the use of GT4CCI it is possible to better understand, track and document concerns, adding gains in terms of quality, reliability and modularity of the entire lifecycle of software

Identificando interesses transversais em modelos de requisitos PL-AOVgraph

The occurrence of problems related to the scattering and tangling phenomenon, such as the difficulty to do system maintenance, increasingly frequent. One way to solve this problem is related to the crosscutting concerns identification. To maximize its benefits, the identification must be performed from early stages of development process, but some works have reported that this has not been done in most of cases, making the system development susceptible to the errors incidence and prone to the refactoring later. This situation affects directly to the quality and cost of the system. PL-AOVgraph is a goal-oriented requirements modeling language which offers support to the relationships representation among requirements and provides separation of crosscutting concerns by crosscutting relationships representation. Therefore, this work presents a semi-automatic method to crosscutting concern identification in requirements specifications written in PL-AOVgraph. An adjacency matrix is used to identify the contributions relationships among the elements. The crosscutting concern identification is based in fan-out analysis of contribution relationships from the informations of adjacency matrix. When identified, the crosscutting relationships are created. And also, this method is implemented as a new module of ReqSys-MDD tool

Novos métodos determinísticos para gerar centros iniciais dos grupos no algoritmo fuzzy C-Means e variantes

Data clustering is applied to various fields such as data mining, image processing and pattern recognition technique. Clustering algorithms splits a data set into clusters such that elements within the same cluster have a high degree of similarity, while elements belonging to different clusters have a high degree of dissimilarity. The Fuzzy C-Means Algorithm (FCM) is a fuzzy clustering algorithm most used and discussed in the literature. The performance of the FCM is strongly affected by the selection of the initial centers of the clusters. Therefore, the choice of a good set of initial cluster centers is very important for the performance of the algorithm. However, in FCM, the choice of initial centers is made randomly, making it difficult to find a good set. This paper proposes three new methods to obtain initial cluster centers, deterministically, the FCM algorithm, and can also be used in variants of the FCM. In this work these initialization methods were applied in variant ckMeans.With the proposed methods, we intend to obtain a set of initial centers which are close to the real cluster centers. With these new approaches startup if you want to reduce the number of iterations to converge these algorithms and processing time without affecting the quality of the cluster or even improve the quality in some cases. Accordingly, cluster validation indices were used to measure the quality of the clusters obtained by the modified FCM and ckMeans algorithms with the proposed initialization methods when applied to various data sets

Urbanização turística em ponta negra: relações de força e processos sociais no período de 1979-2009

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Mapeamento de stakeholders nas áreas conexas de turismo e meio ambiente: um estudo em João Pessoa/PB

The present study aims to understand the perception in a manager perspective of the relationship between the stakeholders of tourism and environmental management in João Pessoa (PB). It is a qualitative, transversal, descriptive and exploratory research, held with keys stakeholders of tourism and environment in the capital of Paraíba. The data were collected through structured interviews and the analysis of the minutes of the municipal council of tourism, called COMTUR/ JP. The data research allowed us to affirm that the environmental stakeholders have a higher academic background than those of tourism, on the other hand the tourism stakeholders‟ have longer experience time than the environmental stakeholders‟. In general, the use of environmental resources for tourism is noticed as positively by the tourism stakeholders‟ and as intermediate for the environmental stakeholders‟, the tourism development is consider to be a non predatory active in João Pessoa, but it is very concentrate in the coastal area, the remnants of Atlantic Forest or protected areas are not used for tourism. The main environmental impacts cause by tourism according to the stakeholders interviewed (tourism and environment) were the environmental degradation of reef, beach pollution and the construction of tourism facilities in areas that should be protected, however, there was a stakeholder who believes that the tourism development in Paraíba is so nascent that it is unable to impact the environment. The performance of SETDE, PBTUR and SUDEMA was consider inconsistent by some of the interviewed stakeholders‟. The NGO representatives believe that the most important thing is a paradigm shift from the entrepreneurs and the local population. Despite the apparently close relationship between tourism and environment management in João Pessoa (PB), some actions of tourism agencies and the state government has left some unhappy important environmental stakeholders indicating that the relationship between tourism and environment in the city is becoming tenser each year

Códigos de sustentação da linguagem no cotidiano prisional do Rio Grande do Norte: penitenciária estadual de Parnamirim

The quarrel, in this study, tells about the language as social practical in the daily of Parnamirim State Prison that is integrated to the Rio Grande do Norte Penitentiary System - SISPERN, destined for men in fulfilment of penalty privative of freedom, in closed regimen. For the accomplishment of the research, the delimited objectives had been to analyze the language repertoires created in the prisional daily, trying to identify how it´s turned into distinct forms of resistance to the mechanisms of control in penitentiary system; to investigate which are the language repertoires created from the new sociability forms developed among prisoners and identify how the language repertoires are expressed in the daily prisional on relations/exercises of power not-institutionalized. In the methodological aspect, the study is in a qualitative boarding, that has as main instrument the interview. The inquiry was possible by means of using instruments for data collection, like as: the direct comment in the prisional daily duly registered as researcher´s ethnographical procedure, the analysis of interns´ cadastre handbooks and the application of half-structuralized interview, to the subjects of the research. The construction and understanding of the study object had been based on authors who argue on the arrest, as: Foucault, Goffman, Carvalho Filho and, in particular was searched the theorical referencial that approaches the language in a social and cultural perspective: Orlandi, Manfred, Bastos and Candiotto, amongst others. Beyond the normative endorsement of the Brazilian legislation, through the Law of Criminal Execution, of the Criminal Code and the Federal Constitution of the country and the legal apparatus in state scope. Still in the research methodological perspective, after the collection the data had been submitted to an analysis of the speech from Foucalt´s theory and in the Orlandi´s perspective, being also qualitative and quantitative. The results had evidenced that the social and juridical profile of the population in the site inquired is not different of others Brazilian prisons, composed for men, in its majority, with age band between 21 and 30 years old, prisoners for practicing crimes against the patrimony, against life, amongst others, and, in special, criminal recidivists. It evidenced, still, that the daily prisional of PSP is characterized for a sociocultural diversity expressed in the relations of power not institutionalized, that contributes for the formation and division of the groups, each one using a set of language codes/ repertoires sustentation. Therefore, the language, in the daily prisional, is one of the ways to understand the singularity of the sociability relations and as social practicing mediated by relations/exercises of power and antagonistic interests, in which each group aims first of all, their own interests. It represents the complexity of the social relations, in the prisional space, with diverse effects, in function of the situation and the moment. The language in the arrest, beyond the communication function, assumes and represents central element for the sociability human being, contributes for its changings and it´s configured as one of the resistance forms of prisoners against the controling, disciplining and monitoring mechanisms of penitentiary system

Grupos sanguíneos e lúpus eritematoso crônico discoide

FUNDAMENTOS: Lesão discoide é a manifestação cutânea mais comum do lúpus eritematoso, e formas cutâneas crônicas apresentam características imunológicas próprias, direcionadas ao polo Th1. Diversas doenças possuem associação com grupos sanguíneos, o que não foi ainda estudado no lúpus discoide. OBJETIVO: Investigar a associação entre tipos sanguíneos (ABO e Rh) e lúpus eritematoso discoide. MÉTODOS: Estudo prospectivo tipo transversal envolvendo tipagem sanguínea ABO e Rh, inquérito de dados clínicos e dosagem de FAN e C4 de portadores de lúpus discoide sem critérios de doença sistêmica, atendidos em hospital universitário. RESULTADOS: Foram incluídos no estudo 69 pacientes, sendo 71,0% do sexo feminino (p 1:160, em 31,9%; e níveis baixos de C4, em 8,7%. Não houve diferença significativa entre as frequências dos grupos sanguíneos dos pacientes e da população local; entretanto, o grupo A foi associado às formas disseminadas da doença (OR 4,1 e p < 0,05). CONCLUSÕES: Grupos sanguíneos de pacientes com lúpus discoide apresentam frequência semelhante à da população; porém, formas clínicas disseminadas foram mais prevalentes entre portadores do grupo A.

Crescimento dos tecidos muscular e adiposo de fêmeas bovinas de diferentes grupos genéticos no modelo biológico superprecoce

Objetivou-se avaliar o crescimento de novilhas de diferentes grupos genéticos no sistema de produção superprecoce. Utilizaram-se 132 novilhas dos seguintes grupos genéticos: 18 ¾ Canchim × ¼ Nelore (¾ CN); 18 ½ Canchim × ½ Nelore (½ CN); 24 Simbrasil -⅝ Simental × ⅜ Nelore; e 72 Three-cross ¼ Simental × ¼ Nelore × ½ Angus. As novilhas foram desmamadas aos 210 dias de idade, com 247,4 ± 16,5 kg de peso vivo (PV), mantidas em creep-feeding durante a fase de cria e confinadas por 132 ± 14 dias até atingirem 350 kg PV e 5 mm de gordura subcutânea, quando, então, foram abatidas. Os grupos genéticos não influenciaram o ganho de peso médio diário, porém a espessura de gordura subcutânea do dorso (EGS) e da garupa (EGG) foi maior nos animais Three-cross, que apresentaram os maiores valores iniciais (1,07 kg/dia). Não houve diferença na área de olho-de-lombo (AOL) inicial, porém a os animais Three-cross apresentaram os maiores valores iniciais. Nos animais do grupo Three-cross, a área de olho-de-lombo (AOL) final e ajustada para 100 kg de peso vivo (PV) foi inferior à observada nos demais grupos, porém o peso final foi superior ao do grupo Simbrasil, com tempo intermediário de confinamento. Ajustando-se os valores de AOL e EGG para o menor número de dias de confinamento (114 dias), animais Simbrasil apresentam maior valor de AOL final e os animais Three-cross e Simbrasil, maior EGG final.

Efeito de valores discrepantes em grupos de contemporâneos na predição dos valores genéticos

Foram simuladas nove populações, cada uma com cinco replicações da variável ganho médio diário (GMD1) com distribuição normal e média 100, variando o tamanho dos grupos e os desvios-padrão. Cada replicação foi dividida de modo a formar grupos que representariam grupos de contemporâneos (GC) e de progênie dentro de GC. Cada GC tinha dez pais. Obtiveram-se três conjuntos: o conjunto 1 com 1.000 grupos de contemporâneos (GC), cada um com 100 observações e dez observações por pai; o conjunto 2, com 2.500 GC, 40 observações e quatro observações por pai; e o conjunto 3, com 5.000 GC, 20 observações e dois filhos por pai. em cada população, gerou-se GMD1, a qual foi transformada em outra variável, da seguinte forma: DIAS1 = 100/GMD1. Calcularam-se para cada pai, dentro de cada GC, as contribuições de cada GC ao valor de cada pai, para GMD1 (Cx) e DIAS1 (Cy). Os efeitos do máximo e da média de DIAS1 no grupo sobre o valor absoluto de Cy foram significativos, mas o R² foi baixo (máximo de 16%). O mínimo de DIAS1 não influenciou o valor de Cy. O máximo e o mínimo de GMD1 sobre Cx foram significativos, mas os R² foram muito baixos (máximo de 2%). A média não influenciou Cx. em grupos de contemporâneos com um animal com valor de GMD muito baixo, o valor de DIAS desse animal será relativamente muito mais alto, o que afetará a média do grupo e os valores de todos os animais do grupo. Esse efeito se refletirá na avaliação de seus pais e será mais uma importante fonte de erros na avaliação genética do rebanho. Assim, a utilização de DIAS em substituição ao GMD como critério de seleção para o melhoramento de bovinos é contra-indicada, pois deverá reduzir a possibilidade de ganho genético para crescimento.

Características de carcaça de caprinos de cinco grupos raciais criados em confinamento

Este trabalho foi realizado com o objetivo de avaliar a influência do grupo racial e da condição sexual nas características da carcaça de caprinos jovens criados em confinamento. Foram utilizados 91 animais, 52 machos e 39 fêmeas, pertencentes a cinco grupos raciais: Alpino, ½Boer + ½Alpino, ½Anglo Nubiano + ½Alpino, ¾Boer + ¼Alpino, e ½Anglo Nubiano + ¼Boer + ¼Alpino. Foi tomado o peso ao jejum, no dia do abate, após 24 horas de jejum de sólidos. Foram tomadas medidas biométricas e de carcaça, objetiva e subjetivamente. O grupo racial influenciou a altura de cernelha, o comprimento interno e externo da carcaça e o comprimento de perna, que foram maiores nos animais Alpinos, bem como a largura do peito, o escore corporal, os índices de compacidade da carcaça e da perna e a cobertura de gordura da carcaça, que foram melhores nos animais com grau de sangue Boer. Animais machos tiveram maior altura de cernelha, medidas da estérnebra com ultrassom, comprimento interno da carcaça, comprimento de perna, profundidade dos tecidos na altura da 3ª e 4ª estérnebras tomadas na carcaça. Nas demais características corporais avaliadas, não foram encontradas diferenças entre grupos raciais e sexo dos animais. O cruzamento do grupo Boer com Alpino reduz o comprimento das carcaças e aumenta a cobertura de gordura e a quantidade de tecidos depositados, mas não influencia o desempenho do animal.
