Minimizing inter-genotypic competition effects to predict genetic values and selection in forestry genetic tests

The effect of competition is an important source of variation in breeding experiments. This study aimed to compare the selection of plants of open-pollinated families of Eucalyptus with and without the use of competition covariables. Genetic values were determined for each family and tree and for the traits height, diameter at breast height and timber volume in a randomized block design, resulting in the variance components, genetic parameters, selection gains, effective size and selection coincidence, with and without the use of covariables. Intergenotypic competition is an important factor of environmental variation. The use of competition covariables generally reduces the estimates of variance components and influences genetic gains in the studied traits. Intergenotypic competition biases the selection of open-pollinated eucalypt progenies, and can result in an erroneous choice of superior genotypes; the inclusion of covariables in the model reduces this influence.

O incesto : discurso e ideologia

This research had as purpose to establish the logic symbolic present in the contemporary society that facilitated the emergency of a public speech on the incest, and, consequently, to demonstrate the ideological nature that structures it. Event associated to the order of the taboo, the incest would be the transgression of the injunction that, second Lévi-Strauss, facilitated the emergency of the Culture while symbolic order, differentiated of the natural order. The injunction of the incest would reveal the elementary and universal structures of the order symbolic presents in the human societies: the demand of the Rule as rule; the reciprocity and the gift, present element in the social changes that it transforms the individuals in partners, increasing a new quality in the transferred value, according to Lévi-Strauss. Starting from this, I developed the hypothesis second which the phenomenon of the alone incest became an event of discursive order and public as right social transformations affected the normative system (social representations, values, moral) regulator of the relationships among the social subjects, being reflected like this, in the own structuring of the Law. A second work hypothesis was developed starting from that. I develop it leaving of the argument that if when inserting the discussion of the thematic of the defense of the children and adolescent rights, being then, considering it while "privileged modality of sexual abuse against children", the present central subjects in the structuring of the social entail would be leaved. Being like this, the partner-institutional speech on the incest would answer the social demands of order and social control, becoming like this, discursive formations of ideological character. This research work tried to follow the hypothesis above referred, demonstrating the singular sense that it will be attributed to the incest in the contemporary society, particularly, its relationship with the Law and the transgression in the contemporary society

Família e TV: mais que dominação e subordinação

This work analises the social relationship between Television and the Family though the resignification of individuals about Television messages and the speeches that they make about Family. Firstly, the objective is to understand if the principles, values and beliefs constructed and communicated (repassed) inside the Family filter the messages from the Mass Media. Secondly, if there still exists a family culture able to forge identity against so many cultural exchanges. Thirdly, what the function of this identity in the production of senses is. In session 1 and 2, a general approach about the dissemination of Mass Media in Society and the pertinence of the work is presented. Session 3 is about the method used: a qualitative research, with thirteen families from Natal-RN, situated in the Middle Class. The theorical base is considered in the fourth session where the reference to the evolution of the Family is made, with enphasis on the Middle Class and some theories that analyze the pheomenom of the Mass Media , specially in the second half of twentieth century. In session 5 and 6, the research data is presented and analyzed. Finally, in the last session, as a conclusion it can be said that the value of the Family as emotional support is reforced by the speeches and practices that interfere in the signification procces, singular aspects, as well as the social repertoire constructed per si and by institutions (including the family) moreover, mediative message is assimilated by the receiver and becomes understood inside the learned speeches during the receiver s history of life, although these messsages are also components in the construction of these repertoire

Natal como destino turístico : um estudo das imagens (re)veladas pela mídia, pelos turistas e suas implicações educacionais e culturais

This thesis is a result of a research on Natal/RN as a tourist destination. We understand that cities are chosen as tourist destinations beyond its cartographic localization, from other dimensions of meanings that, in its set, constitute images. These images are, probably, very different of the images constructed by native and resident populations, who possess relations of identity with the place. The knowledge of the meanings that others attribute to this city as tourist destination, bring us near to the symbolic bonds established by individuals or social groups on the act of their choices, as well as bring us near to the interaction process city-tourists where the expectations are confirmed or not. The images divulgated by the media also participate of the complex formation of the tourist image that is being constructed and available for the different public, in different social contexts. The tourism constitutes a symbolic asset of the modern society, being considered by the studious, as one of the most expressive phenomena of the modernity, for involving each year displacement and the interaction of thousand of people of different cultures in the entire world. All this people s mobilization points to practical social related to personal motivations, to the entailed desired to the idea to travel and to exceed borders. It is already consensus that tourism is a phenomenon of economic growth, generating jobs, income, professional, qualification, bringing improvements for the host cities. Since 1995, in Brazil, the tourism as a sector of the economy, passed to be considered one of the national priorities, and in this perspective, the national politics of the tourism invested in infrastructure of Brazilian cities with high tourist potential, objecting to increase the flows of Brazilian and foreign tourists. Owing to this fact, the country still invests in programs of tourist marketing, mainly divulging the images of the natural beauties of Brazil abroad. And for Brazilians, the campaigns appeal to rescue the feeling to be Brazilian, associating the idea to travel and know its country. Natal city possesses an excellent positioning in the tourist marketing, being predominantly divulgated in national and international level, for its naturalistic singularity, where the images of its natural enchantments as warm water beaches, white dunes, warm weather, constant breeze and an always blue sky are shown as the favorite scene on this city. From what was viewed above that the choice of a tourist destination articulates from a determined imaginary of a place, already constructed or in process of construction, we consider the knowledge of this imaginary a basic learning for the population of the city and especially, for educators, in the formation of professionals in this area and for tourism managers, elaborators of public politics. Based on this estimative, we developed this research that had as a general objective to identify the images that illustrate Natal city as a tourist destination - our objective of study, particularly the meanings and senses attributed by the tourist marketing (hotel s folders) and by the tourists that visited the city during this study. The discussions and reflections that had guided this research had been given from the theoretical link between imaginary and social representation, also considering some interfaces between the fields of communication and symbol. From the studied authors, Baczko (1985) clarifies that the study of social imaginary is directed for the mechanisms and structures of the social life, especially for the intervention accomplishes and efficient of the representations and symbols in the practical collectives, as well as in its direction and orientation . Following this same thought, Moscovici (1978) says that the social representation are produced in communicational and symbolic contexts, and these representations once that already constituted circulate socially as almost tangible entities. Based on this fundament and on the analyze of Barthes (1990), particularly in the approach given to the reading of photographic image, we could observe on hotel s folders that each page evidences senses and meanings of functionality of internal and external spaces, pointing to the way of leisure offered by the keepers of city which is the hotels. About, the leisure that they offer, it is directed to young public, giving meaning to the young myth of personalized leisure tourism on children, young and adults images. The image about security that hotels offer and the singular image of Natal city as a paradise place, provide an idealization of pleasure through the sun, dunes, and beaches and also due to the hospitability of the natives who are assigned as educated . For the tourist that participated on this research, Natal city is tied only by the imaginary of leisure and nature which constitute the emotional link of the relation media-city-tourist. And with such force and fullness of directions the city discloses without tensions and contradictions as a place protected by a mythical and sacred aura. The study also demonstrates us that the potiguar culture remains (almost) forgotten, due to the silenced in this imaginary. In this perspective, we highlight that this culture silence is very close related to the disvalue of education in its general meaning. We defend that the imaginary apprehended constitutes a new reading and a new looking and understanding the tourist reality that comes historically consolidating in this city. In this direction, we glimpse that this study and its future dismemberments can collaborate with the process of rescue the cultural values of the potiguar people, in the way that the meaning of tourist may be redefined, and the tourist image of the city can be also disclosed for its identities particularities of its culture

A formação do professor em diferentes espaços socializadores: um olhar sobre os alunos do curso Pedagogia da Terra da UFRN

This work is an analysis about the teacher's formation starting from certain aspects of its culture. It is supposed that the teacher is constituted in an individual that acts starting from singular aspects, in an individual point of view, but at the same time it interacts with other individuals in an environment strongly marked by the culture. Those two dimensions are representatives of the socio-cultural characteristics and they can be seen in the perspective of the individual and collective identity. Based on those presuppositions we chose, as reference, four environment of formation: the family, the school, the work and the Movement of the Rural Workers Without-Soil/MST (MST: The without-soil-ones in Portuguese) observing as the teachers refers to those environment highlighting, mostly, the formative aspects stood out. The individuals researched are teachers involved in the education of settled communities, who are students of the Earth Pedagogy course of the Universidade Federal do Rio Grande do Norte/UFFRN. For our analyses, we used narrative texts, written by the teachers, as conclusion of the discipline History of the Brazilian Education in which they tell their life histories. The speeches show as the environments of reference influence in their world conceptions, attitudes and values that not just mix in an individual dimension, but also collective. The research make us reflect about the possibility to think on the educational action starting from that understanding of wide formation considering the present elements in the courses of teacher's life

O Curso Normal de 1º Ciclo em Assu/RN (1951-1971)

The aim of this research is the analysis of the history of the Normal Course in the 1st period in Assu, Rio Grande do Norte, since its foundation by the state law no. 621, de 06 December 1951 until its demise, with the implementation of the Course of the Magisterium, by Federal Law 5692 from August 11, 1971. The goal is to answer how it was constituted the operation and the educational practices of this institution, teacher trainers, throughout its existence. For this, we analyze the institution's documents in focus interviews, legislation, of the education, newspapers and books of the season, guiding itself by the studies of Chartier (1991), Elias (2001), Certeau (2001), Frago (1995), Magalhães (2005) and Julia (2001). When dealing with an educational institution, the central category of analysis is the school culture, in which supported the cutting of specific categories of study: the entrance into the Normal Course, the conferring of a degree, the "Normalista Week‖ in Assu and formative elements. The Normal Course from 1st cycle formed teachers in a basic level, differing themselves from schools of teacher education of 2nd Cycle. It was founded in Assu as Regional Training Course and called Ginásio Normal in 1961.In the temporal cut studied, 279 women and 07 men were graduated as Regents of Elementary School, demonstrating a school attended virtually by women. In the narrative, it is restored to the inclusion of female students in the Normal Course, focusing on the processes of registration and the admission exams, graduation events, imbued with discourses on the social role of the teacher and the Party Normalista Week, which valued the sense of belonging with of students to the profession. Through theater plays in the school, of practices forming behaviors and stages of female students in elementary school, training elements are reassembled, demonstrating the discourse of modern education intermingled with the Christian Catholic values of the culture for female education. The reconstruction of the historical identity of this institution sometimes close, sometimes unique, when confronted with other schools of teacher training brings a contribution to the setting of the history of schooling in the state of Rio Grande do Norte

Atenção à saúde da pessoa idosa na estratégia saúde da família no município de Santo Antônio/RN: um estudo de caso

According to demographic estimates, by the year 2025 Brazil will be the sixth country in the world in number of elderly. For this reason, it is a purpose of public policies to help people to reach that age being healthier. The current health care model of health surveillance through the Family Health Strategy (EFS, in portuguese) is configured as a gateway into the care of the elderly in the Unified Health System (SUS, in portuguese). It is also an area of development of practices to promote health, prevention and control of chronic nondegenerative diseases. The aim of this study was to analyze the health care of the elderly provided by ESF professionals for the achievement of a full care. The study is descriptive case study with a quantitative approach, performed in the city of Santo Antônio/RN. The population included all health professionals, who are FHS members of the city that agreed to participate of the survey, a total of 80 professionals. Data were collected using a structured questionnaire, having mostly closed questions and divided into two parts: one containing sociodemographic information of health professionals and vocational training and the other, the activities carried on by the professionals in senior care, being analyzed from a database tabulated in a spreadsheet and discussed according to the descriptive statistics in tables, graphs and charts using frequencies, medians and values of central tendency. It was verified a predominance of professionals who finished highschool, mostly female, aged from 30 to 34 years old, with training completed in the last 10 years, without being graduated in the field of geriatrics or gerontology and mostly without training in gerontology. Family members and caregivers were the components of the social support network most identified by the professionals (66.3%).The elderly access to the Family Health Basic Unit was considered by83.8% of professionals as the most important factor that interferes in the activities of health care of the elderly. Considering the inclusion of the family in care: 98.8% of professionals consider the family as one of the goals of care, but 82.5% assist the family to know their role and participate in the care of the elderly, emphasizing that no professional makes use of tools for evaluating the functionality of the family. Regarding the actions taken to assist the elderly, 91.25% have home visits program to the elderly, 88.75% use the host program; 77.5% know the habits of life, cultural, ethical and religious values of the elderly, their families and their community ;51.25% complement the activities through intersectoral actions, 50%participate in groups of living with the elderly; 33.75% keeps track and maintain updated the health information of the elderly; 11.25% of the professionals perform the Single Therapy Planning (PTS, in portuguese) and few implement the actions to promote health according to PTS; there is a deficit in the number of professional categories in the identification and monitoring of the frail older people in their households. It is concluded that the health care of the elderly developed by ESF professionals differs among the professional categories. It was identified weaknesses in the promotion of an active and healthy aging and also in the establishment of an integrated and full care of the elderly. It is recommended the adoption of permanent educational activities by the City Management, initially for ESF professionals in the the perspective of the guidelines of the National Policy of Health Care for the Elderly and later to the other professionals that are part of the health care network of the elderly, at all levels of care in the city for the development of strategies and practices that promote the improvement of the quality of healthcare for the elderly, expecting concrete and effective results in terms of promoting health within Brazilian reality

Análise do modelo de gestão implantado no Centro de Atenção Psicossocial CAPS II OESTE de 1995 a 2005, situado no distrito sanitário Oeste do município de Natal/RN, à luz da Co-gestão

This dissertation has as aim the praxis of co-management of the health service of CAPS II OESTE of Natal-RN, where health workers, family members got to materialize guidelines and principles of psychiatric Brazilian reform in real possibilities of subjectivity construction, whereas they changed social relations in daily life. The path chosen to record was from testimonials and contributions of those who meant their done. Redeeming this story from social representations of the majority of their builders was an instigating, delicate and rewarding task, emphasizing the living memory, rebuilt in a line of time which could not be found in simple documentary collections. Mainly, by knowing that service routine was intense and had as characteristic the singular mobility itself from a creation process and therefore not always its dynamic allowed adequate records. At the same time, from this occurred the field and bibliographic research which allowed the detailed information from the prior milestones and motivated to the practice here reported. The rereading of concepts in an interface with the reports of the interviewees enabled the verification that the model of mental health advocated by psychiatric reform was understood. Once noticed the presence of the beliefs and values of people in motivating energy for the progress of reform, it has gone to fetch theoretical subsidies of administrative order to understand how they saw this building and that uniqueness has been printed. The theoretical way and praxis have tracked here has allowed to analyze how occurred such a process of production and subjectivity and collectives that when organize enabled themselves for analysis and intervention, including in crisis situations. Therefore, it was revealed that ethical and multi-disciplinarity, the humanitarian sense, the coresponsibility, co-production and horizontal management were the key factors for spread from a changing protagonist. One can thus conclude that co-management from that collective has been multi-disciplinary weaving a cross

Comparison of selective genotyping strategies for prediction of breeding values in a population undergoing selection

Genomewide marker information can improve the reliability of breeding value predictions for young selection candidates in genomic selection. However, the cost of genotyping limits its use to elite animals, and how such selective genotyping affects predictive ability of genomic selection models is an open question. We performed a simulation study to evaluate the quality of breeding value predictions for selection candidates based on different selective genotyping strategies in a population undergoing selection. The genome consisted of 10 chromosomes of 100 cM each. After 5,000 generations of random mating with a population size of 100 (50 males and 50 females), generation G(0) (reference population) was produced via a full factorial mating between the 50 males and 50 females from generation 5,000. Different levels of selection intensities (animals with the largest yield deviation value) in G(0) or random sampling (no selection) were used to produce offspring of G(0) generation (G(1)). Five genotyping strategies were used to choose 500 animals in G(0) to be genotyped: 1) Random: randomly selected animals, 2) Top: animals with largest yield deviation values, 3) Bottom: animals with lowest yield deviations values, 4) Extreme: animals with the 250 largest and the 250 lowest yield deviations values, and 5) Less Related: less genetically related animals. The number of individuals in G(0) and G(1) was fixed at 2,500 each, and different levels of heritability were considered (0.10, 0.25, and 0.50). Additionally, all 5 selective genotyping strategies (Random, Top, Bottom, Extreme, and Less Related) were applied to an indicator trait in generation G(0), and the results were evaluated for the target trait in generation G(1), with the genetic correlation between the 2 traits set to 0.50. The 5 genotyping strategies applied to individuals in G(0) (reference population) were compared in terms of their ability to predict the genetic values of the animals in G(1) (selection candidates). Lower correlations between genomic-based estimates of breeding values (GEBV) and true breeding values (TBV) were obtained when using the Bottom strategy. For Random, Extreme, and Less Related strategies, the correlation between GEBV and TBV became slightly larger as selection intensity decreased and was largest when no selection occurred. These 3 strategies were better than the Top approach. In addition, the Extreme, Random, and Less Related strategies had smaller predictive mean squared errors (PMSE) followed by the Top and Bottom methods. Overall, the Extreme genotyping strategy led to the best predictive ability of breeding values, indicating that animals with extreme yield deviations values in a reference population are the most informative when training genomic selection models.
