Fractures of delayed consolidation and fractures with non-union are commonly found in medical practice and are associated with high morbidity and mortality. Within this context, biochemical and biophysical resource have been studied in an attempt enhance bone healing. Among these may be highlighted the use of bioactive materials and low level laser therapy (LLLT). Several studies suggest that both resources are able to stimulate proliferation of osteoblasts and osteogenesis at the fracture site, promoting a greater deposition of bone mass and accelerating the process of consolidation. So the main purpose of the present work was to evaluate the effects of low-intensity laser (λ = 830nm), with fluencies of 60J/cm² and 120J/cm² and a bioactive ceramic, Biosilicato®, used alone or associated on bone consolidation of the tibial fractures in healthy rats. For the study 60 male Wistar rats were randomly divided in 6 groups: group bone defect control (GCF); group bone defect irradiated with LLLT, at 60 J/cm2 (GL60); group bone defect irradiated with LLLT, at 120 J/cm2 (GL120); group bone defect filled with Biosilicate® (GB); group bone defect filled with Biosilicate® , irradiated with LLLT, at 60 J/cm2 (GB60); and group bone defect filled with Biosilicate®, irradiated with LLLT, at 120 J/cm2 (GB120). A low-energy GaAlAs 830nm, CW, 100 mW, 60 and 120 J.cm² was used in this study. The rats were anesthetized by intraperitoneal injection of ketamine and xylazine 2% and a standardized 2.0-mm-diameter bone defect was created by using a motorized drill under copious irrigation with saline solution. Laser irradiation was initiated immediately after the surgery procedure and it was performed every 48 h for 14 days. After 14 day post-surgery, biomechanical analysis revealed no statistical differences between experimental groups. However, the morphological and morphometric analysis showed that the laser, in the two fluencies evaluated showed values statistically higher than control group and the Biosilicate®. Interestingly, the groups treated with Biosilicate® and laser, in two fluencies, showed statistically lower values of newly formed bone in the area of the defect even when compared with the control group. The scanning electron microscopy showed an intense presence of the biomaterial in bone defects of their animals. From the results obtained in this study, we concluded that the low-intensity laser was more effective in the process of bone repair when compared with biomaterial or the two resources associated.

In the context of construction companies, in general, planning is understood as the task of generating a plan and not as a management process. In most cases, the control is focused on management contracts, than in production. Also, note that these companies do not specify the manner in which they can develop and implement systems for planning and production control. Therefore, in order to assist in the understanding of production management, as well as the cost data, this paper deals with the reflection of Integrated Planning and Control the Cost of Production with the cash flow of the work from the budget pre-prepared and information regarding the process in this phase. Based on financial projections, or outflow of funds in cash flow are obtained parameters for administration of the work. We studied three construction companies that use different strategies and administrative management tools. This paper proposes the end the generic representation of the flow of information relating to the process studied. Thus, this analysis constitutes a contribution can provide agility, formality and support the decision-making to managers.

According to researchers, adolescence has been considered a risk age group for various mental health problems, such as: depression, behavioral problems and substance abuse. However, only a few Brazilian studies investigate mental health problems among young offenders, although the international literature agrees on the fact that juvenile offenders suffer from various mental health problems. Besides mental health, studies indicate that self-esteem, social support and parenting can also affect adolescents behavior and development. The aim of the present study was to identify the profile of male young offenders in treatment and also to identify correlations between levels of mental health, self-esteem, social support and parenting and correlations between these elements and other profile variables, such as age, education levels, substance abuse, among others. Another objective was to identify the adolescents perception of themselves, their difficulties and positive characteristics, their help resources and plans for their future. Fifty adolescents took part in the study. They answered a semi-structured interview and completed the following instruments: Identification Questionnnaire; Young Offenders Profile; Rosenberg Self-Esteem Scale, Social Support Appraisals, Parenting Inventory and Strengths and Difficulties Questionnaire. The scores were calculated according to each instrument. The Pearson Correlation Coefficient was used to identify possible correlations between the scores of these instruments and the Pearson Correlation Coefficient was used to verify possible correlations between the scores of the instruments and the adolescents profile variables. The interview analysis has been carried out through the Content Analysis. The main results indicated that most of the adolescents have low education levels and use marijuana, besides having friends who also use drugs. High selfesteem levels could be observed in this sample. Besides, it was possible to verify that levels of education, social support from teachers and positive parenting might be protection factors against vulnerable behavior, once it was possible to identify negative correlation between social support from teachers and use of cocaine and negative correlations between positive monitoring and recidivism and alcohol abuse, which indicates that the more the adolescents parents perform positive parenting, the lower the recidivism and alcohol abuse levels. We expect that this study can contribute to the planning and implementation of public actions aiming the treatment of young offenders.

Jaú´s region, in the center of the State of São Paulo, is home for a group of companies specialized in the production of women shoes. They are industries, studios or backstitch stands, raw material suppliers, machines and equipments, for the whole productive chain of the shoes industries, including the tanneries, responsible for the supply of the main raw material used: the leather. This structure allows the denomination of this area as Local Cluster, where several players, from public and private sectors, articulate themselves together seeking increase in productivity and competitiveness in the market sector. To best use these arrangements and to increase their efficiency of their actions, it is necessary the use of information and communication technologies that can optimize their processes and information flows, improving their competitiveness. In this context, this exploratory and descriptive research aimed to identify the paper of the Information and Communication Technology and its influence on the competitiveness of these companies based on some indicators like design, quality of the products, flexibility of the production, human resources, infrastructure and others. The collection of data was accomplished through interviews with the managers of a sample of these companies, using the interview instrument elaborated this research, following the appropriate ethical precepts. The results of the interviews indicated a disagreement on forms of management by the accounted companies, which leads to only 10% of them taking part on the Local Cluster. The remaining ones not only do not participate in the cluster, but also show no interest in getting involved in larger events, such as local, regional or national trade fairs, important for the competitiveness of these companies. It is critical for the survival and growth of the cluster a larger awareness of the importance of the junction of efforts by the companies, through a greater fulfillment of meetings, so that they may share problems and solutions and start seeing each other as partners, not rivals. The results obtained will be disseminated to companies and players in the region with a view to supporting the development of the Local Cluster.

Behavioral analysts have used the equivalence class paradigm to investigate and explain the processes involved in the formation and modification of social attitudes. From this perspective, attitudes are defined as equivalence classes established between social groups and certain attributes, with the classes specifying the psychological function of the social group for members of the verbal community. Following this line of research, the present study investigated attitude change by means of the reversal of the equivalence class relating black men to negative symbols. In two versions of the procedure, two pre-tests were conducted involving C-A and A-C relations in order to assess the association made by the participants between pictures of black men and the aforementioned negative symbols. Next, the participants were exposed to a conditional discrimination task with delay, a task in which they were taught the relations A-B (between a positive stimulus and an abstract picture) and B-C (between the abstract picture and pictures of black men). Post-tests assessed whether training had induced the emergence of a new relation between the figures of black men and positive symbols, which emergence would suggest a change of attitude and a reversal of the initial equivalence class exposed during the pre-test. Results showed that, for three of the five participants, the equivalence class relating pictures of black men to positive symbols did not emerge, which suggests resistance to revert the class relating black men to negative symbols. It seems that responses typical of natural settings generalized to the experimental situation, making responding in the latter case insensitive to the arranged reinforcement contingencies. The results are discussed in terms of the extension of the stimulus equivalence paradigm to cases in which the equivalence class comprises stimuli loaded with pre-experimental meaning.

Promoting Primary Education which provides children with thorough development requires the approach of knowledge, attitude and values in training professional educators who act at this level of teaching. Taking into consideration the premise that all the learning which takes place during childhood stays with us throughout life, it is important to observe the assistance that young learners have been receiving during such a period in Primary Education institutions in order to better understand the childish actions which take place in these places and how the children s development have been approached. The present work is the product of a field research carried out at a Primary Education institution in the city of Araraquara in São Paulo, which was accomplished so as to check if and how the mediation work of the teachers during the games take place as well as their contribution to the children s development. Therefore, the attempt was to identify how the professionals involved in this context conceive the play a game idea and their approach towards the kids when they are engaged in such an activity. The methodological procedures adopted in this work consisted of observations and interviews. The observations were carried out both when the children were in the classroom with the teacher and when they were doing free activities in the playground. Some interventions took place during the observations when the children were playing. Afterwards, interviews with the preschool children (3 to 6 years old) were carried out, who were asked about their idea of playing, the games they play and the places where these games take place. Furthermore, we also carried out interviews with the teachers and the educational agents, who are the people who attend the children throughout the period in which they stay at the institution. The methodological and theoretical reference on which this work was based was the Historical and Cultural theory by Vigotsky, which supported the data collection and analysis. The most significant results which were obtained show that the teachers assume a passive posture towards the possible mediation opportunities, thus restricting their acting to the explanation of a certain rule to the game or pulling the kids apart in case of conflicts. Considering the actions performed by the researcher during the games, it was possible to check that the main mediation opportunities should be based on constant observation, which is an important instrument to achieve mediations which are appropriate to the learning needs of the children. The importance of a deeper theoretical training for the teachers should also be highlighted, one which not only contributes to the games at the school day-to-day , but also so that these moments are legitimated through intentional mediations in order to promote an effective and thorough development of the children.

The Canchim has been used in beef cattle as an alternative to production intensification. Canchim (5/8 Charolais + 3/8 Zebu) and MA (offspring of Charolais bulls and 1/2 Canchim + 1/2 Zebu cows) constitute a synthetic beef cattle breed which has a good growth potential and tropical adaptation but suboptimal fat deposition under pasture. Backfat thickness (BF), total fat amount and distribution of fat have a strong impact on carcass and meat quality in beef cattle. For this reason, research has been conducted to increase fat deposition in this breed, including the search for molecular markers to identify animals with high genetic potential for fat deposition. To incorporate molecular genetics into breeding programs in beef cattle, it is essential that the association between molecular markers and production traits is evaluated in the population in which they are to be used. There are reports of many candidate genes and chromosomal segments associated with variation in fat deposition in cattle. The objective of this study was to identify SNPs associated to backfat thickness in Canchim. To achieve this objective we searched for SNPs in development and differentiation enhancing factor 1 and insulin-like growth factor binding protein 3 genes, tested the association of SNPs in the insulin-like growth factor binding protein 3, peroxisome proliferative active receptor gamma coactivator 1A, proteasome 26S subunit ATPase 1, development and differentiation enhancing factor 1, corticotropin releasing hormone and fatty acid binding protein 4 genes with fat thickness in Canchim and MA beef cattle. We also analyzed the existence of genomic regions associated with backfat thickness in these populations using a 54 K chip in extreme phenotypes. From the associated regions we selected the ones of BTA14 to validate the association by analysis of haplotypes in the whole population. The SNPs analyzed in development and differentiation enhancing factor 1 and fatty acid binding protein 4 genes were associated with variation in backfat thickness, wereas no association was found for the SNPs of the insulin-like growth factor binding protein 3, peroxisome proliferative active receptor gamma coactivator 1A, proteasome 26S subunit ATPase 1 and corticotropin releasing hormone genes. Additionally, two chromosomal regions of BTA14 were associated with the trait in this work.

This text is going to show many ways that compose the IDH until the year of 2007 that they are going to be talked the analysis the development for the development from the countries for the Program of the Union Nation to the development from the Union Nation Organizations PNUD ONU. The first chapter is going to show the definition of IDH its particulars, methods of calculus and its structurations beyond the observation from three ways that componde the indicator in the actuality income per capita, health, and education. For helping in your understand, we are going to include the index of Gini to help us in our analysis. In the second chapter, we are going to do an analysis commented and compared of the Brazilian s IDH in terms of inner regions for that we could understand the discrepancies that there are in the same country being utile when analysis the Brazilian s IDH in general forms. In the third and forth chapter we are going to do the analysis of IDH among the nations, showing the evolution and the retreat of each country got along the years, their deficiencies in determinates sectors like social or economics, the characteristics and the reasons of the countries show us the variables of optimization of the quality of live in remains from nations that hale index medium and others in precarious situations. We are going to analyses the divergences that there we are among many region in the globe where we are going to do the calculus between the sub-regions, for examples we are going to analyses the IDH of Emirates Arabs, Africa, Subssariana, Latin America inside others. In the forth chapter we are going to show the IDH in 2007 with the brief report of the IDH the 2009 that gets their relatives facts to indicaters of 2006 the insert of Brazil in context latin and world-wide the observation of first placing, to the last, and the motives that took these countries to get these classification. In the fifth chapter we are going to show the criticism that are done in the index at the meaning of the same not portray with the total real fidelity condition of development that a nation meet and the possible inclusion of others variables that could do the IDH the index much precise. Also be boarding the difficulties of methodologies that exist in case of others variables go in to the index. At the of this text we are going to reunite the annexed of some interviews with professors, or specialist in the field of socialeconomics about the problematization of the index.

The porcelainized stoneware has been outstanding in the current market of ceramic tiles because it offers excellent technical and esthetic features. In this research traditional ceramic raw materials were selected and a standard formulation reported in the literature was adopted, aiming to replace the vitreous phase former (feldspar) from the composition by two fluxing agents at high temperature. The objective was to evaluate these materials as a technical alternative with lower cost (30-40%), since, in the porcelain, the amount of flux former is very large, and represents approximately 50% of all raw materials used. The nepheline syenite was the natural raw material selected to replace the feldspar due to the fact that it belongs to the family of feldspathoids, and has similar physicochemical characteristics, therefore, high fluxing efficiency. The second vitreous phase former was a synthetic material, named flux agent, with physical and chemical characteristics very different from those of the feldspar and even greater fluxing efficiency. The replacement of feldspar occurred in complete and in part, through combinations of the alternative fluxes. The masses were processed from mixing of powders, wet milling, drying, desagglomeration, compaction and firing. In addition to the curves of vitrification, techniques, as sedimentometry, dilatometry, flexure strength test, electron microscopy, piroplastic deformation measurements and X-ray diffraction were used to characterize the material sintered at different temperatures. The most important results show that it is possible to combine nepheline and synthetic flux as alternative material other than feldspar because they promote vitrification at lower temperatures. Compositions with both fluxes showed low values of water absorption (<0.1%) and high mechanical strength (45 MPa) when compared to the standard, despite of the higher piroplastic deformation. The presence of nepheline does not change qualitatively the formation of phases and the flow generates new crystalline phases, in according to phases diagram.

To overcome the scenarios of environmental degradation in the State of Mato Grosso, requires a dialogical model between schools, communities and government to order the construction and implementation of Public Policies for Environmental Education. This thesis aimed to understand the policy in environmental education of the State Department of Education, as an unfinished process, with the possibility of reversing unwanted scenarios for social control exercise their power of coauthorship and citizenship. In order to meet this goal, we used throughout the thesis based on qualitative research methodologies, participatory research, bibliographic and documental research diagnostic evaluation, in search of hybridization between the evaluation results and processes, observing the natural phenomenon. The sustainability analysis was infused, initially for a critical educational praxis of Environmental Education in the Learning System TM. And in understanding the process used to formulate public policies in Mato Grosso, in the ethical axiom of non-neutrality of subjects, establishing dialogues with SEDUC MT, Researcher Group on Environmental Education and Training Centres of Vocational Education Basic. By launching an evaluative look on Policy Environmental Education, focusing on the educational materials, the tactics of implementation. The results are offered prognoses of the construction and implementation of the Environmental Education Policy SEDUC MT (PREA). The path ahead for construction of Public Policies for Environmental Education in the spaces must be limited by the educated social participation, since its construction process (initial proposal) to its evaluation. "Learning with the error" this is the tactic that could revive the school units of Mato Grosso Environmental Education, but greatly participatory, with the audience needed to bring schools and communities feel part of their formative processes and decision-making, it based the political processes necessary for teaching an education policy that is environmentally and in search of a more just and sustainable..

In this study, we used the capture-recapture procedure to estimate the size of a closed population. We analysed three di_erent statistics models. For each one of these models we determined - through several methods of eliminating nuisance parameters - the likelihood function and the pro_le, conditional, uniform integrated, Je_reys integrated and generalized integrated likelihood functions of the population size, except for the last model where we determined a function that is analogous to the conditional likelihood function, called integrated restricted likelihood function. In each instance we determined the respectives maximum likelihood estimates, the empirical con_dence intervals and the empirical mean squared errors of the estimates for the population size and we studied, using simulated data, the performances of the models.

The climatic resort of Santa Rita do Passa Quatro-SP, located in the north-east region of the state of Sao Paulo, has about 27,500 inhabitants, as well as other cities of the country, reserved its right proportions, currently suffers from several problems of urban and environmental degradations, which are often caused by human action, mainly by the indiscriminate appropriation of their territories. It is known that in the face of intense population growth in the period of industrialization, coupled with a lack of commitment of some municipal administrations with the urbanenvironmental zoning, the territorial planning, the production of space in cities, etc., many cities live great mistake processes of occupation and without any concern for sustainable development. Thus, in order to recover the vitality of the degraded environment and the quality of life of its inhabitants, some brazilian cities are already taking very important decisions to realize their strategic planing, master plans, etc. Therefore, the characterization of the potentiality and environmental fragility of the physical environment of the cities are key to subsidize their urbanenvironmental planning, is also an important tool to aid in monitoring the land occupation in its urban and suburban regions in a technically adequate. Thus, this study aims to characterize the potentiality and environmental fragility of the part physical environment of the city of Santa Rita do Passa Quatro, in order to provide information that can subsidize studies of urban planning, territorial planning and also other related studies the identification, mitigation of environmental problems and guidelines for the prevention of future problems in the physical occupation of the region studied.

The potentiodynamic and potentiostatic electrochemical synthesis were performed for the eletrosynthesis of nanofibers and nanoparticles of polyaniline on gold electrodes without the use of physical or chemical templates. The electrochemical system used is composed of aniline and hydrochloric acid and the formation of PANI nanostructures was by analyzed by the following parameters: scan rate, concentration of monomer; potential interval; number of cycles, temperature and pH. The films of PANI were characterized by an electrochemical technique (voltammetry cyclic), two microscopic techniques (electron microscopy scanning and atomic force microscopy) and a spectroscopic technique (UV-Vis absorption). It was conducted the study of the influence of the number of cycles in the oxidation state of the polyaniline film and the comparison between models of nucleation and growth of metals with the process of formation of polyaniline nanoparticles. The studies have demonstrated that the variation on the concentration of monomer, the electrochemical technique used in eletrosynthesis, temperature and pH are fundamental steps to determine the morphology of polyaniline. The comparison of theoretical models of nucleation and growth metals with the formation of polyaniline nanoparticles showed a good correlation with instantaneous nucleation with two-dimensional growth.

Cinemateca Brasileira, the largest film archive in Brazil, for years has stored, catalogued and conserved a large number of Brazilian films that have survived to the present day. But in order for a film to be thoroughly preserved it needs to be known by both the general public and specialized audiences. Some collections manage to be fully preserved while others remain stored without the adequate circulation: this is the case of the home movies collection. The aim of the current research is the valorization of this collection through its physical description and the investigation about its content. Throughout this process, the cataloguing procedures currently in practice at the archive and the specificities of the collection of home movies regarding its informational status will be described. From this investigation specific work methods and forms of analysis will be proposed. In a broader perspective, historical background and conceptual discussions about the formation of the amateur field, the use of cinema in the domestic realm, the production of images in the private domain and the amateur cinema columns of the magazine Cinearte will add to the cataloguing procedures of Cinemateca Brasileira.

The control of surgical site infection, especially during clean is important, especially when exposed bone in orthopedic surgery. A study was conducted exploratory study aimed to assess the impact of particulate matter, air and microbial resistance profile of Staphylococcus aureus in suspension for the intraoperative orthopedic procedures in a medium-sized hospital in São Carlos, SP. In the initial ten samples, the results indicate presence of filamentous fungi in 69% of the samples and 93.75% of the bacterial samples were identified as Gram positive and Gram negative 6.25%. In the 10 samples analyzed in the second stage, the UFC's of bacteria had an average of 97.80%, standard deviation of 51.60%, coefficient of variation of 52.75% and range between 21 and 178. We identified the presence of Staphylococcus aureus, Staphylococcus spp. and Shigella spp. 25%, 75% and 25% of samples, respectively. Held an antibiotic for Staphylococcus aureus isolated from the air in the operating room, and found that the strain had high levels of resistance to most antibiotics used, with sensitivity only two of 15 antimicrobial agents tested. The presence of suspended particles was above the recommended standard for the surgery, suggesting the need for an effective control of air quality. It was observed that during surgery there was a significant increase in suspended particles in accordance with WHO standards and CONAMA. The increase in the number of the surgical team in the room probably generated an increase of suspended particles and hence an increase in microbial range. Of the surgeries performed, one can see that in 70% of the operating room door was closed and 50% with air conditioning was off. In 3 (60%) of surgeries in which the air conditioning was off, we found the incidence of a bacterial genus.

Digital television will allow the transmission of new services, with a significant increase in the amount of information available to users compared to traditional analog system. Given that growth of possible applications, recommendation systems have emerged as useful tools to help viewers cope with this overload of information, allowing identify their needs and preferences. For this reason, this work presents a solution to support the development of recommender systems, by adding a new module in the middleware Ginga entitled Recommender TV. Thus, it was implemented an abstraction layer that allows developers of applications for interactive digital television, specifically for developers of recommender systems, be concerned with the interface and navigability of their systems, leaving questions of low-level module Recommender TV manage. Issues regarding the low level processing the new module presented in this work allows the implementation of different recommender systems, quickly and efficiently. The use of the results provided by such systems will assist us to better understand the implementation of interactive digital television.

Health personal are constantly exposed to biological hazards by the nature of their work, which involves the use of sharps and contact with body fluids. Exposure involving biological materials is a serious event by the potential contamination that exposes professionals, subject to diseases such as hepatitis B, hepatitis C and AIDS. Knowing the factors related to the occurrence of these events enables the development of preventive actions. This study is an integrative review of the literature to characterize the scientific literature on the subject and identify prevention strategies recommended in studies published in the SciELO Brazil. We used the keywords "Accidents, Occupational ", "Occupational Risks ", "Occupational Exposure ", "Exposure to Biological Agents ", "Needlestick Injuries", Universal Precautions ", "Health Personnel ", "Nursing" and "Nurses' Aides ". The 54 selected articles were read in full by completing a roadmap for data collection. The data were entered into Microsoft Excel for further characterization and analysis. The Revista Latino Americana de Enfermagem published the most articles on the subject, 72% of articles were published between 2004 to 2008, 74% of studies were conducted in the Southeast, 59% of the state of Sao Paulo. The occupation was the most studied of nursing workers. Approximately 75% of the studies were descriptive according to their objectives and 61% as a quantitative approach, 7% were case-control studies, 9% of studies of action research, 15% review studies, 19% prevalence and 50% of studies survey collecting information on knowledge, perceptions, opinions and attitudes of the people, through interviews and / or self-administered questionnaires. More than a third of the studies characterize the accident, the occupations most affected, the circumstances of the accident and its evolution. Less than 20% address the risks faced by professionals in their workplace and 17% focuses on the consequences of the accident and post-exposure. Accidents are not only related to individual risk factors or protection. Accidents are also influenced by the environment where workers are inserted and the organizational structure of the institution. The articles of prevention of occupational accidents with exposure to biological material discuss the adhesion of measures Protection Standard, hepatitis B vaccination, biosecurity education courses in health and actions to minimize the occurrence of accidents. The most cited recommendations for prevention of accidents with biological material were: continuing education, adoption of standard precaution measures, worker participation in the discussion of the risks, action planning based on the evaluation of working conditions and adoption of safety devices. Only 2 articles (4%) investigate the causes of the accident after its occurrence. Studies of this kind are important and need to be encouraged, as it allows the origin of the accident and from there to propose preventive measures.

This research was carried out through fieldwork in the Piaçagüera Indigenous Land, located on the southern coast of São Paulo, between 2007 and 2009. It proposes an analysis of the Tupi Guarani relations construction with other indigenous groups, especially with Guarani Mbya, non-Indians, and also the relations between themselves. In a context of territorial conflict and the formation of a new village in which they discussed ways to rescue the culture, I realized that people can operate distances and approaches to what they consider being Guarani, Tupi and indigenous people, based on a speech that deals with the mixture. The Tupi Guarani people say that they are mixed because of the marriages that occurred between the Guarani and the Tupi as the basis of their ethnicity. They also speak about the mixture with other Indians and whit nonindigenous people - like white and black people. It thus becomes clear that they establish a kind of gradation between being "more Indian" and "less Indian" that is linked to characteristics typically considered Guarani, for example, the mobility and the territoriality. Through the relationships that the Tupi Guarani people establish among themselves and with others, it is possible to understand how the knowledge and the knowing the language, prayers, traditions and the Tupi and Guarani ethnic identities are constructed and constantly updated.

Two problems related to Partial Least Squares method are considered in this work. Heteroscedastic errors and an asymmetrical error distribution. In the _rst part of this work a methodology is developed which allows, based in PLS methods, to estimate the model parameters in the presence of non-constant error variance. This technique is compared with the usual PLS method which considers homoscedastic erros. The PLS method is an distribution free approach, that is, it does not assume any distribution for the error terms. In order to estimate the heterocedastic structure an probability distribution is attributed to the errors, similar to the idea of Bastien et al: (2005). In this work, it is proposed a class of asymmetric distributions, the asymmetric normal distribution, presented in Azzalini (1985), which includes the normal distribution as a particular case. For the heteroscedasticity detection is proposed adaptations of the White test, the Goldfeld-Quandt test and an test proposed by Xei et al: (2009), which is used for testing the homogeneity of the scale parameter and/or signi_cance of autocorrelation in skew-normal nonlinear regression model. The test methods are illustrated with two numerical examples. All the methods present in the work are illustrated with simulated and real datasets.

This study aimed to understand the meaning that the family in social vulnerability attributes to the social support and the social network in their experience with cancer. This is a qualitative study guided by Symbolic Interactionism as a theoretical framework, and Grounded Theory as a methodological reference. Data were collected through interviews with families at high social vulnerability, which have one member diagnosed with cancer referred by a Family Health Care Unit in a countryside city in São Paulo. From the continuous comparative analysis of the data emerged two dynamically interrelated phenomena: Realizing themselves vulnerable, which shows the family situation when facing the adversities imposed by the disease and Supporting each other to care, which shows the moves of the family seeking for support to care for the member of the family with cancer while maintaining family balance. Families reorganize and restructure to overcome obstacles and provide care to their beloved, often giving rise to a new family, which includes people who have responded to the demand for social support and exclude those who do not. The social context of these families influences the family system. The interaction that occurs in the subsystems and in the familiar supersystem directly affects the meanings attributed by the families and affect their actions. The relationship of these families with the Public Health System and other Public Services, and especially with the Family Health Care Unit, reveals the difficulties encountered by families to meet their needs. The development of this study offers support to family care of the patient with cancer in a situation of social vulnerability, according to their real needs.
