Genetic and environmental effects on age at first farrowing in sows in southeastern Brazil

We evaluated genetic and environmental factors affecting age at first farrowing of sows in the Brazilian southeast. For this purpose, 466 observations regarding the age at first farrowing were made for Dalland-C40 (c) animals belonging to two herds. The effects of the environmental factors on this trait were assessed by means of a model that included, as random effects, the influence of the sow's father and mother and, as fixed effects, the influence the year of birth, the herd and the birth season, along with the covariable litter size at birth. The variance components were estimated using the derivative-free restricted maximum likelihood method. The estimated mean was 354.8 +/- 25.87 days, with a coefficient of variation of 7.29%. Significant effects on the trait were observed for the herd, the year and the season of birth; but a linear effect of litter size at birth on the age at first farrowing was not observed. The boar did not significantly contribute to the variation occurring among the sows, whereas the sow's mother caused significant variation. The heritability estimate for the age at first farrowing was 0.44 +/- 0.15, which is considered high. We concluded that herd effect and year and season of birth should be taken into consideration for an accurate genetic comparison; consequently, the animals should be joined into contemporary groups.

Um olhar sobre as veredas rosianas.

The present work objective to study the configurations that the hinterland it acquires in the workmanship Great hinterland: trails, of Guimarães Rosa demonstrating as this author humanize this element, conferring to it characters universal mystics and through investigations, uncertainties, the auto-corrections of Riobaldo that become hinterland a metaphor of the human interior. Three are the chapters, that they will guide this work: the chapter 1 presents as element key for characterization of the epic one in Great hinterland: trails, the mining hinterland replete of trails, palco of exuberant vegetation, huge and multidimensional scene, where it has an entrecruzamento of fiction and reality. It retakes quarrel of critics as Manuel Cavalcanti Proença, Roberto Schwarz, on the existing epic character in the Great hinterland: trails, constructed from deriving myths of the universal culture, that they had been become popular. The brave and gracious knight, that it has its representabilidade in the popular culture. Thus the medieval hero, the knight represented for the Riobaldo personage, it is cognominado by Proença as Don Riobaldo of the Urucuia, knight of the general fields. O chapter 2 is a study on the popular culture in Rosa and Cascudo. Cascudo the example of Rosa also is exímio studious of the brazilian life, the regionalization and the popular manifestations proceeding from other cultures. O chapter 3 it has as focus of analysis two mitopoéticas personages: Diadorim e Luzia-Homem, which in the cited narratives they generally they assume functions generally atribute the men. Since children, if they dresses male. Valley to point out that Diadorim is not characterized as man, since in Great hinterland:trails if trajaq always as gunman. Luzia, when complete 18 anos pass if to dress as woman, but the stigma of male and female, inherited of the time where it coexisted the father folloies it for all the life. They suffer pain to have been born to fight and to não conhecer to love. They die you deliver the God. This study detects exactly that Diadorim and Luzia-Homem, are personages associates the myths of the universal culture and popular (sphinx, Jellyfish, Venus, Mother d water), that they possess similarities n the archetypes, that transit between the sexos masculine and feminine, without any sexual connotation, possesss it proper code of honr, of this not abdicating ahead of the death. Parallel, in this chapter two cascudianas workmanships willbe studies, that contemplate thematic of the dressed woman of man and being the woman without disguice: the enchantment tale Maria Gomes and romance Flower of tragics romances. The first one will be revisited in order to present subject in Great hinterland:trails through the Diadorim personage. As it will discourse on cases of brave women, cited for Cascudo, immortalized for the tradition, who had made history, that already is not disfarçam of men to carry through acts of bravery and honor.

Hydrocephalus and moderate mental retardation in a boy with Van der Woude phenotype and IRF6 gene mutation

In this report, we present a boy with lower lip pits, distinct craniofacial dysmorphism with cleft lip and palate, central nervous system malformation, and severe mental retardation. Similar but less pronounced facial findings were present in his mentally normal mother and maternal grandfather, both presenting with lower lip pits. Cleft lip was present in patient's father. Analysis of the VWS1 and VWS2 regions were performed to elucidate the molecular basis of the phenotype of the propositus. Screening or mutations at the IRF6 gene detected a pathogenic mutation (c.960G > C) in the propositus and in his mother; and a single nucleotide polymorphism (c.175-5C > G) in the propositus and in his father. Clinical and genetic aspects of this case are discussed.

O teatro de Deus: a construção do espaço sagrado de juazeiro a partir de narrativas femininas (Ceará, 1889-1898)

In this work, we discuss the construction of Juazeiro in the state of Ceará -, as a sacred space from the analysis of the testimonies of nine religious women called beatas in an Episcopal process in the late nineteenth century. This process was initiated in 1891 to investigate the occurrence of an Eucharistic miracle with beata Maria Magdalena do Espírito Santo de Araújo. We show that the punitive strategies of the Diocese eventually caused a reordering of pilgrimages to Juazeiro which until 1894 worshipped the Precious Blood and that after the condemnation of the phenomena by the Holy See are rearranged around the figure of Father Cicero Romão Batista, under the pretext of worshipping the priest himself and also Nossa Senhora das Dores, currently the patron saint of the city of Juazeiro do Norte.

O reino encantado do sertão: uma crítica da produção e do fechamento da representação do sertão no romance de Ariano Suassuna

Based on the relation history, literature and space, this work examines the production and the closing of the representation of the hinterland in the Romance d A Pedra do Reino of the paraiban writer Ariano Suassuna. Inspired by method proposed by deconstructionist by Jacques Derrida, our reflection decomposes the writing scene of Suassuna by means of it s tracks to interpret the operation of the representation of the space-hinterland for the speech of the writer. Being thus, we present the elements chosen for Suassuna to weave an identification it s with this space-hinterland, taking a priori as a sentimental place and of familiar origin . The construction of this relation of belonging in great is measured grounded for a familiar memory entangled in the context politician who culminated in the Revolution of 1930 and that he resulted for the writer in the death of father. Suassuna launches a look on the identity and the Brazilian culture that guided in the tradition concept it searchs to deny the gift grounding its speech in the return to the past, a past order . Specifically in it s romance we notice to exist the fusing of these tracks in the production of a representation of the hinterland that it intends to close a concept of this space and its culture. Soon, the idea of kingdom sends to the space of the enchantments manufactured in infancy and retaken by the intellectual radical who in the anxiety of honor the father figure, does not save efforts in constructing a space representation that, over all, either faithful the representation that it searchs to trace of proper itself. Under one it marks of universality , the hinterland-kingdom of Suassuna if discloses eurocentric in the measure where it perpetuates discurse the filiation of the European cultural traditions.

O padre, o filósofo e o profeta : a América de Simão de Vasconcelos

To build an Portuguese America, after discovering at the beginning of XVI century, the Europeans used the physic, politic colonization and also a space ideological domain using write texts, chronicles, and started making a conceive America that was more European than American. One of those chronicles was the Society of Jesus Chronicle written by father Simão de Vasconcelos, a Jesuit. So our object is recognizing in this chronicle the ways that this father had imagined the America. We are looking to answer how the Jesuit use some references to Classic Antiquity (meanly Aristotle and Samuel) because how this action until happen in the Renascence (XVII century) the intellectual production certainly involve renascent topoi. To get this we used some authors that study Intellectual/ Cultural History like Burckhardt e Ginzburg and some authors from Speech Analyses like Certeau and Foucault, to, in the end, can understand how Simão de Vasconcelos created his Brazil

Corpo e fronteira: o diário de Samuel Fritz e a conquista do espaço amazônico

Considering that the Jesuitical tradition which Father Samuel Fritz belonged, has a clear political and institutional dimension that reveals itself in the missionary initiative placed since the Trento Council, his journal is a experience story as missionary at Maynás region during the period from 1686 until 1725. In his narrative, a series of data related to the conquer of Amazonia, conflicts among the Iberic Kingdoms and french, dutches and british, transformation of culture and space close the period of the Madrid Deal. I´ll explore the men and space relationship, in this case, the missionary in his special practice, therefore an effective and geometrical politic for border control was only applied at 1750 with reformist governments and that Amazônia was, until now, an object of autonomous initiatives, not being until now a priority focused state politics action like the ones in the central regions (silver mines) and that the missionary action of Samuel Fritz represented ant that moment represented the most important border advance to the Spanish Kingdom, coinciding with the end of the borders previously set in Madrid and Santo Idelfonso, I´ll put the question of how and with which politics the experience of Fritz in Maynás could represent an advance about Amazônia space. Then I´ll approach the problem about three aspects that are chapters: The first one was focused to the Iberic Kingdoms atlantic politics and the internal geopolitical relationships they created as the centre and the border emerging a new order; in the second chapter I studied the special transformation cause by the encounter and conflicts between the Indian and European order generating a new organization; in the third chapter I´ll examined the political border of the state and the emergency of the missionary body as an institution, with the tradition and missionary action as support, or not, to the exploration of the east border of Spanish America influencing the delimitation process of the border between Portugal and Spain

O pai presente: o desvelar da paternidade em uma família contemporânea

O objeto deste estudo é a figura concreta de um pai, presente em sua corporalidade e afetividade, que se depara com a demanda subjetiva, advinda da exigência de revisão de seu papel no mundo contemporâneo. Buscamos encontrar a paternidade que acolhe e convive com o processo de transformações em marcha: o pai que transita entre valores novos e arcaicos. O acesso a este conhecimento se deu através do método clínico de pesquisa, com apoio da psicanálise. Sem submeter os participantes ao tratamento psicanalítico, aplica seus conceitos na interpretação de fenômeno que tem dimensão subjetiva e também, social. Adotamos a entrevista como principal instrumento e a análise qualitativa enquanto estratégia, por permitir relevância à fala do entrevistado e dela extrair o dado significativo para nossas indagações.

Avaliação genética da eficiência reprodutiva em vacas pardo-suíças por meio da análise de sobrevivência

Among the traits of economic importance to dairy cattle livestock those related to sexual precocity and longevity of the herd are essential to the success of the activity, because the stayability time of a cow in a herd is determined by their productive and reproductive lives. In Brazil, there are few studies about the reproductive efficiency of Swiss-Brown cows and no study was found using the methodology of survival analysis applied to this breed. Thus, in the first chapter of this study, the age at first calving from Swiss-Brown heifers was analyzed as the time until the event by the nonparametric method of Kaplan-Meier and the gamma shared frailty model, under the survival analysis methodology. Survival and hazard rate curves associated with this event were estimated and identified the influence of covariates on such time. The mean and median times at the first calving were 987.77 and 1,003 days, respectively, and significant covariates by the Log-Rank test, through Kaplan-Meier analysis, were birth season, calving year, sire (cow s father) and calving season. In the analysis by frailty model, the breeding values and the frailties of the sires (fathers) for the calving were predicted modeling the risk function of each cow as a function of the birth season as fixed covariate and sire as random covariate. The frailty followed the gamma distribution. Sires with high and positive breeding values possess high frailties, what means shorter survival time of their daughters to the event, i.e., reduction in the age at first calving of them. The second chapter aimed to evaluate the longevity of dairy cows using the nonparametric Kaplan-Meier and the Cox and Weibull proportional hazards models. It were simulated 10,000 records of the longevity trait from Brown-Swiss cows involving their respective times until the occurrence of five consecutive calvings (event), considered here as typical of a long-lived cow. The covariates considered in the database were age at first calving, herd and sire (cow s father). All covariates had influence on the longevity of cows by Log-Rank and Wilcoxon tests. The mean and median times to the occurrence of the event were 2,436.285 and 2,437 days, respectively. Sires that have higher breeding values also have a greater risk of that their daughters reach the five consecutive calvings until 84 months

Quando as mulheres se tornam mães: a história reprodutiva feminina numa visão evolucionista

In this thesis we tested evolutionary hypotheses, with empirically collected data, in a sample composed of pregnant Brazilian women. We consider that during pregnancy and soon after the baby's birth fundamental reproductive decisions take place, given the complete feminine involvement with the reproduction phenomenon. The results are presented in four empirical articles related to the history of female reproduction. The topics approached were mate selection, the life-history theory, the strategies of parental investment and postpartum depression. Data collection was accomplished through interviews with pregnant women and after the baby s birth, with a sample composed of women from two income classes (low income and middle class), in Natal, Brazil. With respect to mate selection, the results suggest that a real situation of reproductive mate selection shows significant differences when compared to the results obtained in studies involving potential mate selection (Article I). Considering the life-history theory, we have partially confirmed the hypothesis of the father`s absence influencing the development of the young female syndrome (Article II). In regard to parental investment strategies and the decrease of fatherhood uncertainty, we identified a larger attribution of the baby's resemblance after birth with the father, confirming our hypothesis (Article III). The results related to postpartum depression occurrence partially support the hypothesis that it is an evolutionary adaptation (Article IV). This thesis is part of a consolidation movement of Evolutionary Psychology in Brazil and it presents results on female reproductive history hitherto unpublished.

Ausência do pai ao longo do desenvolvimento ontogenético e indicadores de desconto de futuro: uma contribuição da psicologia evolucionista

The new Evolutionary Psychology (E. P.) paradigm has been trying to understand how the human beings make their decisions over time regarding the most diverse variables, always bearing in mind that such a cognitive process is due to a complex natural selection process that occurred millions of years ago. One of the main topics discussed by this new paradigm is the issue of parental investment, i.e., the care the parents provide to an offspring at the expense of the investment into a new one. The present work sought to integrate these two topics, trying to understand how some variables modulate the process of decision making in a sample of the city of Natal, Rio Grande do Norte state. It was investigated the hypothesis that the presence of both parents, along the individual development, could signal a more favorable environment, providing clues to the individual that he could assume a competitive position at the socio-biological market. His decisions, therefore, could be guided by long-term investments with aims to obtain more robust rewards. On the contrary, those who has suffered for some moment the absence of one the parents could develop theirselves in a not so competitive way, starting to choose immediate benefits - but lesser ones -, since the future would be less predictable due to their worse development conditions. This study involved 152 individuals from three higher education institutions, one of them being public and the others being private ones. In the results found, there was no difference between children of coupled parents and children of deceased or divorced parents concerning discount rates. The levels of hopelessness did not affect the discount rates of children of single parents when compared to children of coupled parents. Not having one of the parents because of divorce made the child to tend to present lower scores in the domain of social relations of WHOQOL - Bref, whilst the absence of the father by death made the scores lower in the domain of environment. The results indicate that loosing one of the parents along the development influences the individual's quality of life perception, but the measurement method of future discounting rates by means of financial choices is not sensitive to this variation

Motivações para adoção: uma perspectiva da Psicologia Evolucionista

Parental investment increases the offspring s survival, though it decreases the opportunities for the parents to invest in a future progeny. In a broad sense, this investment is directed to one s own descendant, but in some cases, such as in adoption, resources are directed to non-relatives even in the absence of fitness benefits. Once there are many factors involved in adoption, this study investigated adopters candidates, aiming to analyze aspects considered by them for adopting, based on the Evolutionary Psychology s perspective. We analyzed the judicial proceedings´ files people who had been inlisted for adoption at the 2ª Childhood and Adolescence Law Court, Natal-RN. The adopter s motivations were classified into biological or social reasons. A relationship between adopters´ age and kind of motivation was found: requirements of young people were related to biological reasons while requirements of the old ones were related to social reasons. Fertility, mainly female requirer´s fertility, underlie this relationship, considering that women fertility is strongly influenced by age. The reasons to adopt were also related to the age of the desired child, once that people who wanted children older than 25 months alleged social reasons while those that wanted younger babies alleged biological reasons. There are lots of motives to adopt a child, but the phenomenon of adoption is broadly acknowledged by society as an act of love and the adoptive parents are often regarded as kind and generous people. It was observed, instead, that the reasons to adopt comes from the adopters themselves, related to the fulfillment of personal needs, such as increasing the family, carrying out mother/father role or having a company or someone to care form them in elderly age

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

Maternidade na adolescência: significados e repercussões

From evidence of an existing divergence of opinion among professionals and adolescents using the prenatal and delivery services at a Public Health Unit, aimed to study meanings and consequences of adolescent motherhood among 26 adolescent mothers living in Felipe Camarão, low income district of Natal, capital do Estado do Rio Grande do Norte. Living in a peripheral neighbourhood with a high rate of adolescent mothers in relation to the total new-born, those girls, with offspring among 8 and 12 months age, during interview and focus groups, expressed a different appreciation of their experience than the hegemonic idea among professionals that considers pregnancy and motherhood as unwanted or undesired. With age among 15 and 20 years old, having 53,8% initiated sexual activity before being 15 years old, revealed that the pregnancy was desired in 73,1% of cases, but showing at the same time a social context marked by strong gender oppression and lack of opportunities as consequence of social class deprivation. Life projects, almost always limited to the constitution of a traditional nuclear family, with a purveyor father and care giver mother, appears with very limited possibilities: 46,2% already lived with her partner before becoming pregnant and for 50% of the participants, the birth of the child did not provoke changes in plans and projects. Lack of economical recourses and precarious public services available, together with an idealized maternity role seems to produce extra apprehension among those girls, resulting in frustration and disillusion. As a fact, 92,3% of those adolescents would recommend other adolescent to postpone the maternity project

A manifestação da vontade da criança na disputa judicial da guarda: escuta psicanalítica/

Currently, in custody disputes, the child has the right to be heard and to have its opinion considered, according to its age and maturity. The psychologist/psychoanalyst who works in the Family Court is required to produce a Report with the purpose of helping the Court´s decision. The present research aims to discuss and to find guiding principles for the hearing of the declaration of the child´s will in a custody dispute by its parents, from a psychoanalytical perspective. The case of a nine year old girl that affirmed in Court the desire of living with the mother and seeing the father only once a year is the starting point of this theoretical research over the psychoanalytic fundaments of the hearing of the case, how it appeared in that experience and how it was reflected in the report. Throughout this work, the peculiarities of psychoanalysis as a way of understanding the subject and the conditions that must be observed so that a sctrictu sensu analytic hearing is possible are studied. Then we present a reflection of the case, in the light of the theories studied, verifying that we could observe in the experience: i) the assumption of a subject of the unconscious, divided and desire full that constitutes itself from the oedipic structuration, that leads to the difference between speech and speak; ii) the concept of the child as having a sexuality of its own; iii) a hearing based on the ethic principles of psychoanalysis and the analysts'' formation. In the final considerations, we state that the institutional demand of a meaning for the case is a great difficulty for the analyst since he works from a place of 'not-knowing"
