Pollination is an effective ecosystem service, responsible for increasing the quantity and quality of fruits and seeds formed. Due to the self-incompatibility of some species of agricultural interest, cross-pollination is required and the limiting of pollinating species such affects its production. The yellow passion fruit (Passiflora edulis f. flavicarpa.), a selfincompatible specie is dependent on cross-pollination to form fruit. Thus, the general aim of this study was to study the biology of pollination and reproduction in P. edulis f. flavicarpa, emphasizing the efficacy of pollinators for this specie. The specific aims were: 1) to evaluate the richness, visitation frequency and the behavior of visitors in Passiflora edulis f. flavicarpa flowers.; 2) to compare the efficacy in the formation of fruits and seeds of P. edulis f. flavicarpa through individual and two visits by Xylocopa frontalis with manual crosspollination and natural pollination and 3) assess whether there is pollen limitation through comparison between natural and manual cross-pollination. Visitors were observed during the flowering period, from January to April 2015, totaling 106 hours of observations. For fruiting testing and seed counts: 1) manual cross pollination (n = 37 flowers); 2) natural pollination (n = 52 flowers); 3) pollination by single visit of X. frontalis (n = 41 flowers) and 4) pollination by two visits of X. frontalis. Were identified bee species of Apis, Bombus, Centris, Epicharis, Eulaema, Melipona, Oxaea, Trigona and Xylocopa genera, Apidae, being also observed an individual belonging to Halictidae family. Insects belonging to other orders were also observed, including different species of butterflies (Lepidoptera), bugs (Hemiptera), flies (Diptera), beetles (Coleoptera) and the presence of family Trochilidae hummingbirds. The specie A. mellifera (thief behavior) and X. frontalis (predominantly pollinator behavior) were the most frequent in the plantation with 58.11% and 30.20% respectively of occurrence. Regarding pollination tests, we observed the formation of fruits in all the treatments. Flowers of manual cross-pollination obtained the highest fruiting rate when compared to other treatments. The fruiting rate through manual cross-pollination was significantly higher than that obtained in natural conditions (X2 = 12.676; degree of freedom = 1; p <0.05) indicating that there is pollen limitation in natural pollination. Regarding the number of seeds, an analysis of variance (ANOVA) indicated no significant difference between the mean number of seeds produced in different reviews pollination. Conclude that there is richness of floral visitors specie in the study area, and that between them, the main pollinator species are those with larger, mainly bees belonging to the genus Xylocopa. Larger fruiting rates obtained by manual cross-pollination treatment suggest that more than one visit is needed to promote greater production rate in passion fruit crops.

Vitiligo is a depigmentation’s disorder of the skin, with an incidence of up to 2% of the population, particularly among female population. Investigations, both nationals and internationals, have pointed out that women suffering from this disease presented low selfesteem and high rates of depression. This study aimed to: 1) examine the occurrence of psychiatric morbidity in patients with vitiligo; 2) identify the severity of discomfort attributed to the presence of spots in different body regions; and 3) correlating discomfort attributed to the location of the spot, self-esteem, psychiatric comorbidities in general, and particularly of depression. For gathering information was used an online questionnaire, constructed and available in Google Docs base. Adults women diagnosed with vitiligo were invited to participate in the study, mainly through social networks and websites that offer information about the disease. The questionnaire presented initially the Informed Consent of the Research and, in the sequence, introduced issues related to socioeconomic variables and of living with the disease, namely: gender, age, education, occupation, marital status, family income; When he was diagnosed, the specialty of the professional that closed this diagnosis, among others. It was requested to indicate the body´s regions affected by stains and the degree of distressed related to each of them. Three instruments were available to assess various psychological conditions, namely: 1) Transversal Inventory PROMIS Level 1 for adults which assess risks related with mental health’s of 13 disorders; 2) Transversal Inventory PROMIS Level 2 Depression; and, 3) Self-Esteem Rosenberg Inventory. The participants presented aged 16-64 years, and the majority was declared single (41%), white (54.7%), with family income equal to or less than three minimum wages (38.7%), living in different regions of the country. The diagnosis would have happened 10 years or less (41.9%), by professional dermatologist (115 participants). 42.7% of the participants showed signs of depression, 50.4% showed the occurrence of six or more symptoms associated with different mental disorders and 17.9% had low self-esteem scores. Low self-esteem was related to high depression scores and a greater number of symptoms related to various disorders. high intensities of distress were associated with areas of greatest social exposure; higher the intensity of distress reported discomfort, greater were the indicators of various mental disorders, severe depression and lower scores on self-esteem. The discussion sought to establish convergent and divergent aspects of those observed in the literature in the area, particularly considering aspects of social cognition and social relations as an important element for building self-esteem and mental health.

The use of a simplified consolidated bioprocess for the conversion of biomass using enzymes produced in-house (integrated into the process of converting lignocellulosic biomass) may enable significant increases in the production of bioethanol, without the need for expansion of cultivated area. With this motivation, the present work had as objective the study of the steps of production of (hemi)cellulases by solid-state fermentation (SSF) and the use of whole fermentation medium (WFM) for saccharification of biomass and subsequent alcoholic fermentation within the context of a consolidated bioprocess for the 2G ethanol production. To this end, firstly, the selection of the cultivation conditions for the production of enzymes directly using the sugarcane bagasse pretreated by steam explosion (SEB) as SSF substrate was studied. Thus, different fungi were cultivated in isolation and in co-cultivation, including the study of the use of wheat bran and lactose as inducers in the production of enzymes. In order to optimize the enzymatic hydrolysis (EH) step with the WFM from SSF, it was evaluated the influence of the operating parameters and the use of soy protein, Tween 80, PEG 1500 and bovine serum albumin (BSA) as additives. Finally, the alcoholic fermentation step was performed for the selected condition for the overall validation of this bioprocess. The results obtained in the conditions which maximize the production of enzymes, using SEB as substrate, were: addition of lactose at 0.075 g/g of substrate and wheat bran in the mass ratio 1:1 relative to the substrate, which led to an increase of activity of 73% for beta-glucosidase, 67% for endoglucanase, and 72% for xylanase, compared to the control condition using SEB as the substrate, without the presence of lactose or wheat bran. Cultivations under SSF followed by the EH step with the WFM showed that the co-cultivation were, in most cases, better in the conversion of SEB into fermentable sugars. The co-cultivation that presented the best result when compared to the best-isolated cultivation of Aspergillus niger was the Trichoderma reesei with Aspergillus oryzae, which has promoted an increase of 47% in the glucose production. The evaluation of operating parameters (pH, temperature and stirring) during the enzymatic hydrolysis step with the WFM from SSF showed that the saccharification process performed under the condition of pH 4.8, 200 RPM and 50 °C presented the best conversion of lignocellulosic biomass. This operational condition is the same already used in the conventional process of enzymatic hydrolysis with commercial extract enzymes. The addition of additives (soy protein and Tween 80) improved the saccharification process, whereas the addition of soy protein (0.5% w/v) lead to a 50% increase in glucose release. The alcoholic fermentation carried out for validating the overall integration process at the best condition of cultivation /hydrolysis gave a yield of 83.5% of the theoretical yield and volumetric productivity of ethanol (QP) 4.77 g/L.h. These results show that all process steps can be performed sequentially in the same reactor, thus denoting the proposed consolidated bioprocess.

The National Humanization Policy (PNH ) is considered a proposed policy readjustment Health System (SUS) from the perspective of promoting the autonomy of the actors involved: users, health worker and manager. Profile and abilities of municipalities have impact on health policy processes and promoting function of managers on these aimed to identify the perceptions and actions of managers at the cities level on the PNH , user embracement and the co-management. It is an exploratory research with qualitative approach whose data processing was due to the thematic analysis. Data production took place through individual interviews, oriented from semi-structured, with directors/health and a member of the 06 municipalities management team of a health region secretaries belonging to a Regional Department of Health's State of São Paulo, totaling 12 participants. The results demonstrates how that the managers, in general, are unaware of the PNH and user embracement and co-management. This study showed that decision-making processes within the territories of municipalities still reproduce centralizing management models, in which users and workers are not considered, and that this configuration reflects the context of health in the municipalities. Although it was possible to identify management practices concerned with little inclusive and democratic models as opposed to proposing the PNH.

Currently the Down syndrome challenge the school and educators to outline new methodologies and pedagogical practices. Consequently, the teacher is an important mediator to conception internalization, which will be acquired. This way, the objective of this study was analyze written language of a down syndrome’s student in the inclusive classroom context. In addition, as specifics objectives: a) observe the teaching strategies used by the teacher of regular classroom to teach the reading and writing and b) analyze the writing production of the Down syndrome’s student. In this direction, the present study it is qualitative and it is guided in a case study, had as reference the historical-cultural theoretical approach and the dates were collected in a regular classroom second grade in the elementary school. The instruments used were a semi-structured interview and a semi structured used with the teacher of the classroom, participant observation and photographs of the school production of student during the classes. The results has showed an initial and continue training need for teacher who have in their classrooms students with Down syndrome, and with it, thinking with new strategies, because, as was evidence in this research the literacy activities for those students are guided for repetition and memorization techniques. In addition, few different activities were developed with the student been a lagged literacy processes. The written production of the student analyzed, indicated that despite not be literate, the participant student started to attribute signification for your draws, that it is a step for written language acquisition.

In my Master's research, I evaluated the Japanese Kendō practice as a Japaneseness device, i.e., something that sought to "make Japanese". In this manufacturing process, Kendō focused on three connected planes: the 'Spirit' [Ki], the Sword and the Body. While development of the foregoing, this doctoral thesis sought to analyze data from life stories of Kendō practitioners and Documents about the notion of Ki – Life Force, Vital Energy – through an extensive ethnographic research in Brazil and Japan. The notion of Ki introduced itself as an important way to understanding the Japanese Culture itself, in a close relationship with an idiosyncratic notion of Love - Ai. The result was a theoretical and analytical potentiality to understand the Japanese Kinship and Japanese-and-Non-Japanese’s Family Studies, including cultural recognition processes whose assessment was made by anthropological and comparative perspectives

A child with Autism Spectrum Disorder (ASD) can present difficulties in the acquisition of symbolic behavior in general, including in reading. Educational programs via computerized curriculum based on stimulus equivalence provide children opportunities to learn reading repertoire. This study aimed at the implementation and evaluation of a computerized procedure for teaching reading fifteen-syllable words (isolated) for children with ASD, based on stimulus equivalence paradigm. As a secondary goal of the study we built games to work at home, seeking parental involvement in reading learning of their children. In the study participated three autistic children and their parents. We used a multiple baseline design of sets of words, combined with pre and post-test. The procedure began with the implementation of the pre-test after conducting five stages of teaching and finally the post-test. In the five teaching steps, gaming sessions and teaching sessions of isolated words through computerized curriculum were performed. In general, the results showed that children made gains in the repertoire of reading, although they showed no generalization of learning to generalized reading significantly. Parents were involved in the application of games and used reinforcement and prompt during the sessions properly. Keywords: reading, computerized instruction, games, children with ASD, parents.

Several teaching procedures based on the stimulus equivalence paradigm have been developed and proved effective in improving reading performance. Expanding the research on the subject, this study aimed to determine the effects of using a teaching reading sentences procedure with this paradigm. The study used programmed sentences with multiple and critical differences in order to check, as a secondary measure, possible patterns of responding under the control of stimuli in this situation and the effects of these patterns on learning to read. The sentences were composed of subject, verb and object. Ten children with seven to nine years old, without clinical diagnosis, attending in the first primary education cycle, participated. The study consisted of four phases and 12 steps. The sentences and the difficulty of discrimination varied over the phases: simple words of the Portuguese language and comparisons had multiple differences between them; simple words and critical differences; complex words and multiple differences; and complex words and critical differences. The steps contemplated pretest and posttest, teaching AB relations (match figures to spoken sentences) and AC (match printed sentences to spoken sentences), testing of BD relations (nomination of the figure), CD (nomination of the printed sentence), BC (match printed sentences to the figures) and CB (match figures to the printed sentences), Reading Test of recombinative generalization sentences, Reading Test of comparisons sentences and test of learning maintenance after 30 days. Nine of ten participants had higher performance at posttest than in the pretest. The children had more errors in the phases that had critical differences. In the Reading Test of recombinative generalization sentences, two of ten children had a high percentage of correct answers. The results suggest that the procedure promoted the learning of sentences during the teaching; however, it was not sufficient for recombinative generalization.

Architecture-Driven Modernization (ADM) is a model-based initiative for standardizing reengineering processes. Its most important meta-model is KDM (Knowledge Discovery Metamodel), which is a platform and language-independent ISO standard. A important step in an Architecture-Driven Modernization is the Architectural Conformance Checking (ACC), whose goal is to identify the violations between the Planned (PA) and Current Architectures (CA) of a system. Although there are ACC approaches that act on source-code or proprietary models, there is none for hystems represented as KDM. This absence hinders the dissemination of ADM and increases the interest for research that investigates the suitability of KDM in this context. Therefore, in this paper, we present ArchKDM, a KDMbased ACC approach that relies exclusively on the KDM meta-model for representing i) the legacy system under analysis; ii) the PA; iii) the CA; and iv) the violations between them. ArchKDM is composed of three tool-supported steps: 1) Specifying the Planned Architecture; 2) Extracting the Current Architecture; and 3) Performing the Checking. Our goal is to investigate the suitability of KDM as the main representation in all ACC steps as well as to deliver an ACC approach in the ADM context. We evaluated steps 2 and 3 of the approach using two real-world systems and the results showed no false positives and negatives.

Partes de África, by the Portuguese writer Helder Macedo, is intriguing due to fragmentation and profusion of speeches that assembles when unites diverse voices, memory, history, autobiography and fiction in what the narrator calls a mosaic-inlaid mirrors. If on the one hand the narrative fragmentation is not new, on the other, the mirroring undertaken between its various pieces inserts the narrative in an undecidable place, refusing theories and binarisms in which the colonial world was engineered. In addition, there is a constant flirtation with referentiality, highlighted by the metaficcionality of a narrator self-conscious of the relativity of truth. For this reason, we pursue the hypothesis that Partes de África refuses the traditional speech forms which are identified with the idea of the writing’s ability to apprehend the truth about a subject or about his own time, as is the case with traditional history, the autobiography or the novels of eighteenth and nineteenth century. It is evident in this novel, a narrative way of relating to reality that is typical of the contemporary world, which conceives the notion of subject and history as categories constantly changing because they are hopelessly being modified by the future. Subject and history are an eternal construction and, to show this dynamic character, the narrator makes use of strategies used by traditional speeches to create an illusion of reality just to destabilize them, presenting them rather an effect of reality.

The pelvic floor muscles have an important role in supporting the abdominal viscera and also in urinary and fecal continence, also have an important role in sexual function of women. It is through the functional assessment of these muscles that is verified the efficiency of conservative treatment, for that were developed some tools, however, the dynamometer is the only one equipment which performs direct assessment of strength. The vaginal dynamometer is a device of difficult access, since most of it was developed by research groups and only one device is commercially available, but it still used only for study and research. This study is composed of a systematic review of the literature about vaginal dynamometers and a search for prior patents, to identify devices that perform direct assessment of the strength of the pelvic floor muscles to identify the technologies developed and their settings, as well as search for commercial equipment. The objective of this study was to propose a device to evaluate the pelvic floor muscles directly and objectively, from the prior art search. The objective of this study was to propose a device to evaluate the pelvic floor muscles directly and objectively, from the prior art search. Were found 13 equipments in the literature that varied in cylindrical, specular and spherical that have different dimensions in relation to the length and diameter. They have different numbers of sensors and different parameters evaluated, as well as maximum force of contraction of the pelvic floor muscles, some equipments evaluated resistance and tonus. Were found 14 patents of which eight were related to the equipment found in the literature. The patents have a less specific detail and may have more than one configuration for the same equipment. Only one commercial equipment was found, but its sale is restricted only to research, until this moment. At the end of this review, it was possible to make a proposal for intravaginal device, as well as integrating relevant characteristics to assess the direct force of the pelvic floor as well as other important aspects to evaluate the function of these muscles, and attempts to overcome some limitations of the present equipment in literature. It is concluded from the literature that the dynamometer is an important equipment to be developed because of its contribution to evaluation of treatment and greater understanding of the pathophysiology, and has great potential for innovation

Service-based communication is becoming increasingly relevant, as seen in the Internet of Things scenarios. Choosing an adequate service however can be a difficult task, as this form of communication may involve sensible resources and data. A trustworthy, safe, and privacy preserving mechanism is desirable for service selection. Reputation systems can help in this selection. This thesis presents a reputation system for service selection based on the security and privacy mechanisms of crypto-coins. In order to evaluate the performance of the proposed mechanism in the identification of low quality service providers we also investigated the use of different formulations used to determine a reputation based on peer voting. Results from simulation show the proposed system architecture is viable and supports large adoption via a scalable infrastructure. The performance analysis of different formulations for the calculus of reputations also shows that the recent behavior of an entity is the most impacting factor in establishing its reputation.

Studies show that the main causes of failures in software projects are related to the requirements specification document that contains incomplete, inconsistent and ambiguous requirements. The software development with quality requires a complete and consistent requirements specification. One of the problems faced by software engineers is that, sometimes, they do not know completely the application domain and have difficulty in communication with stakeholders to obtain the requirements specification. The knowledge reuse obtained from completed projects can facilitate the identification and writing of requirements in the elaboration of a complete and consistent requirements document. In the information systems domain it is common to find a set of requirements that has similar characteristics, which is present in different systems, indicating a possible requirement pattern. The advantage of using requirements patterns is provide to the software engineer a starting point for the elaboration of the requirements document, instead of starting from scratch to solve known problems. The requirements patterns can contribute to the improvement of software quality, minimizing the development time and cost, because previously defined and tested solutions are reused. In this dissertation it was developed a set of requirements patterns to assist the software engineer in the elaboration of requirements document of information systems. In order to facilitate and standardize the requirements document elaborated it was also developed a computational support based in that set of patterns. Case studies were used to evaluate the patterns and the computational support, with graduate students of UFSCar and UEMG, aiming prove the effectiveness of this proposal, as wellas to identify possible improvements. Analyzing the case studies conducted, it can be inferred that there is evidence that the elaborated patterns assist in the elaboration of a more complete requirements document, that the computational support is easy to use, and that there was an increased productivity, mainly of inexperienced developers.

Inductive Decision Trees (DT) are mechanisms based on the symbolic paradigm of machine learning which main characteristics are easy interpretability and low computational cost. Though they are widely used, the DTs can represent problems with just discrete or continuous variables. However, for some problems, the variables are not well represented in this way. In order to improve DTs, the Fuzzy Decision Trees (FDT) were developed, adding the ability to deal with fuzzy variables to the Inductive Decision Trees, making them capable to deal with imprecise knowledge. In this text, it is presented a new algorithm for fuzzy decision trees induction. Its fuzification method is applied during the induction and it is inspired by the C4.5’s partitioning method for continuous attributes. The proposed algorithm was tested with 20 datasets from UCI repository (LICHMAN, 2013). It was compared with other three algorithms that implement different solutions to classification problem: C4.5, which induces an Inductive Decision Tree, FURIA, that induces a Rule-based Fuzzy System and FuzzyDT, which induces a Fuzzy Decision Tree where the fuzification is done before tree’s induction is performed. The results are presented in Chapter 4.

The main purpose of this dissertation is to analyze the capacity of sectors of the Brazilian economy to tranfer their productivity gains over the production chain, in the period 2000-2009. In this way, an adjustment is performed, through the structural decomposition technique of the input-output analysis of Dietzenbacher and Los (1998), of the method proposed by Greenhalgh e Gregory (2000). The fundamental assumptions, based on the structuralist current, are that the Industry tends to have larger increases in productivity and linkages with other segments of the economy, especially when compared to the Services. Together, these attributes would make that the productivity gains of the industrial sector propagate more intensely by the productive chain. The results show that in the period analyzed, the Agricultural and Services were the primarily responsible for transmiting these increments for the rest of the economy, instead of Industry, which moved forward losses of productivity. However, despite the Services have become more productive and transferred these gains over the production chain, the average transmission power of its segments was relatively low compared to the Industry's ability to transmit forward its productivity losses. This is because a considerable portion of the increments of the tertiary sector occurred in Personal Services, segment with reduced links in the production chain and whose goods meet, mainly, the individual consumer. The fact that the Industry ´s power transmission is, on average, higher than that of Services implies that if the industrial sector had increase its productivity, rather than decrease it, greater productivity gains would have been transmitted to the other segments of the economy that have been verified by the productivity gains of Services. However, it is important to stress that certain activities of the tertiary sector showed high potential to transfer these increments. This was the case of the Knowledge-Intensive Business Services.

This research aims to understand how the control of practices in public spaces is elaborated, wich is part of the urban surveillance so called "fiscalização" of Belo Horizonte, under the protection of the Código de Posturas (2003). This is a social control which focuses on the regulation of street vendors activities, marked as "social problem" in a context of "urban order" promotion. Further than an analysis that prioritizes organizational or institutional ideal types, this research developed between 2013 and 2015, priorized the data collection "from inside", from an interactional point of view. For this, qualitative research techniques (interviews and observation) were operated in order to keep the subjects working practices as the main reference for descriptions and analyzes. These workers work daily on city streets in direct contact with the street vendors (interacting with other people, like other professional groups) in different part of the fronts of street surveillance: the plantões, the equipes de Apoio and the operações. In general, the practices of these assistants anticipates the participation of their bosses, the fiscais integrados (and other authorities in this field), reducing, as an effect, their workload. At the same time, these assistants actively participate of the situational production of references of differenciation (between formal /informal, bearable/unbearable) and social control as a whole. The research effort was to come up, in an interrelated manner, the various aspects that make up the street surveillance as a social construction. At the beginning, I analysed the strategic and managerial aspects enrolled in practical work of these agents in different working arrangements and enviroments, giving a focus on how the control is produced in a negotiated manner, although it is constantly rationalized as a tool for public space management. The analysis was enlarged by replacing the focus on the continuities and discontinuities between the private life aspects and the work aspects, from the reconstruction of trajectories of some of the research subjects. Through this perspective, it was possible to work out with some different social aspects (such as class and gender) in order to observe and describe the practices that reveal the main basis and senses of this social and relational control. All this conjugated analysis dimensions demonstrate how this particular control is produced. At the same time, it shows, from this field, some modes of circulation of power.

Emission reduction of greenhouse gases to the atmosphere in order to control global warming is an urgent need fully accepted by the international community. Ceramic materials play an important role in the possible solutions for this problem, with emphasis on 8 mol% Yttria-Stabilized Zirconia (8YSZ). 8YSZ is the state of the art material for high temperature Solid Oxide Fuel Cell (SOFC) electrolytes, however its ionic conductivity is not high enough to enable cell operation at intermediate temperatures (T~600°C), which are considered to be optimal for technological feasibility, considering cost, efficiency and life span. The goal of this work was to investigate the role of new interfaces in electrolytes with 8YSZ as the major phase, in order to obtain ceramic materials with unique microstructures, as well as higher conductivity than conventional ones. In order to achieve this goal, the following were investigated: i) homogeneous composite consisting of 8YSZ single crystals dispersed and oriented in 8YSZ polycrystalline matrix; ii) heterogeneous composite formed by Al2O3 single crystals (sapphire) dispersed and oriented in 8YSZ polycrystalline matrix; iii) heterogeneous composite consisting of intercalated layers of 8YSZ and Al2O3 polycrystalline films, which were deposited on Al2O3 mono and polycrystalline substrates. All analyzed systems showed higher electrical conductivity than 8YSZ samples with conventional microstructure. Emphasis should be made to the homogeneous composite (8YSZ polycrystalline matrix with 8YSZ monocrystalline fiber oriented) which showed electrical conductivity 18 times higher than 8YSZ with conventional microstructure, which can enable SOFC operation at intermediate temperatures.

The use of technology based on Field Programmable Gate Arrays (FPGAs), a reconfigurable technology, has become a frequent object of study. This technique is feasible and a promising application in the development of embedded systems, however, the difficulty in finding a flexible and efficient way to perform such an application is their bigger problem. In this work, a virtual and reconfigurable architecture (AVR) in FPGA for hardware applications is presented using a Genetic Programming Software on the development of an optimal reconfiguration for this AVR, in order to build a hardware capable of performing a given task in an embedded system. This proposal is a simple, flexible and efficient way to achieve appropriate applications in embedded systems, when compared to other reconfigurable hardware techniques. The representation of phenotype of the proposed evolutionary system is based on a bi-dimensional network function elements (EF). The GPLAB tool for MATLAB is used in Genetic Programming, and the solution found by this procedure is converted into a memory mapping to represent the best solution, where it is used to reconfigure the hardware. In the tests, GPLAB found results for logic circuits in a few generations, and for image filters containing efficient solutions, where there was little hardware occupation, especially memory, in the cases this has been presented, with a reduced chromosome size, shows a proposal efficiency.

The purchasing management plays a strategic role in public organizations, since their function is supply them with inputs, raw materials and services needed to achieve their goals. However, the public procurement processes are highly regulated and bureaucratic, causing disorders affecting the performance of acquisitions. The objective of this research was to propose and implement a system for improving the internal purchasing process in a Federal Institution of Higher Education (IFES) based on Knowledge Management. The research method used was action research and the organization studied was the Federal University of São Carlos (UFSCar). The results comprised the development of a systematic, based on knowledge management, to improve the purchasing process and its application in unit case, which involved four steps: 1] diagnosis of the problem situation: mapping process information flow purchasing, identification of stakeholders, problem causes, the knowledge conversion processes; identification of potential knowledge management initiatives and the selection of operational focus; 2] implementation; 3] Evaluation and 4] solution Replication. The conclusion is based on theoretical discussion and analysis of results that knowledge management can contribute to the improvement of public organizations purchasing process by implementing solutions focused on the actors and the knowledge conversion processes.

Coparenting involves interactions between the mother and father of a child for whom they are jointly responsible. However, when a review of the Brazilian literature was conducted, no studies on the validation of coparenting instruments, for use in Brazil, were found. Thus, the objectives of this study were: (a) compare coparenting instruments described in the international literature, and select the one with the strongest theoretical foundations and the most robust psychometric properties, to adapt for use in Brazil; and (b) compare the Brazilian version of the selected instrument with the original version, to verify their semantic, conceptual, cultural, idiomatic, operational and measurement equivalence. Using a systematic search in electronic databases, 35 articles about the validation of eight coparenting instruments were found. After analyzing the theoretical and psychometric evidence, the Coparenting Relationship Scale (CRS) was chosen, to adapt for use in Brazil. Next, an initial translation of the CRS was revised, using the transcultural adaptation process, leading to the preparation of the Escala da Relação Coparental (ERC). In the final step of this process, individual interviews were conducted with each member of 25 couples, who all had at least one child between 3 and 6 years of age. The participants ranged in age between 24 and 49 years, and the couples earned an average of BRL 6,420.00 (sd = BRL 4,598.54), a month. For each item of the instrument, the participants: (a) indicated the extent to which the behavior being described represented their own coparenting relationship (using a scale of agreement, ranging from 0 to 6); (b) indicated if they believed that these behaviors influenced the quality of the interactions established by couples raising children, and, if so, how positive or negative this impact would be (evaluated using a scale from 1 to 10); and (c) gave examples of situations in which they had behaved in the described way. The levels of internal consistency for the ERC were within the expected range for three of the seven subscales. Average subscale scores were high on the positive dimensions (4.53 to 5.35) and low on the two negative subscales (0.63 and 0.78). Between 76 – 100% of the respondents rated each behavior as positive or negative, in accordance with the structure of the original instrument, and their examples confirmed this. Thus, the results of this study indicate that coparenting is being incorporated into parenting relationships, in Brazil, and that the participants’ perceptions of the ERC are convergent with the structure of the original version. However, the ERC must be tested with a second sample, to verify and resolve possible internal consistency problems, in addition to conducting studies to obtain evidence of the validity of this instrument, based on relationships with external variables. If the ERC can be validated for use in Brazil, it will be useful for evaluating intervention programs that aim to increase parents’ positive interactions, with respect to raising their children.
