Ethics on scientific research is approached and often discussed in several areas of knowledge connected to health. In the Administration area there are very few studies which approach the topic of ethics on research. The present paper tried to fill in this gap in the production of knowledge about the topic, investigating how the ethical principles found in the literature and in the codes of conduct are noticed and taken into account in Administration research activities developed by acting researchers in Administration Post Graduation Programs. Theoretically speaking, the study was based mainly on the approaches by Creswell (2007) and Bell and Bryman (2007), which discuss the research ethical principles. Methodologically speaking it was all about an exploratory kind of study, with qualitative research approach. Upon data collection, personal interviews were made aiming at its depth and focus groups were formed. The first stage had interviews with four experienced researchers who took part on a teaching and researching event and on the second stage we used the focus group technique. The focus groups were done in four college institutions along with the post graduation programs in Administration in the states of Rio Grande do Norte, Paraíba and Pernambuco, in Brazil. The results suggest the existence of general principles and parameters for the scientific research recommended in the literature and on official resolution. However, in the Administration area, there are only a few recommendations of good practices when it comes to submitting articles for scientific publications but we found no guidance with ethical principles and parameters which cover all the activities in the scientific research and which specifically meet the research particularities in Administration. The main ethical dilemma pointed by the researchers refers to ethical questions which arise at the time of data collection and on disclosing the results. Most researchers do not know the guidelines and the ethical norms on ethics about research that we have in our country neither do they send in their projects to the research ethics committee. When dilemma arises, they decide the ethical question based on their values and common sense. These elements confirm the thesis that the researcher s procedure in the research activities in Administration is predominantly signed by personal values or by common sense and less by ethical principles, whether by not knowing the normative instruments related to ethics or by disagreeing with any disciplining rules on ethical behavior in the research

Flowering is a fundamental process in the life cycle for plant. This process is marked by vegetative to reproductive apical meristem conversion, due to interactions between several factors, both internal and external to plant. Therefore, eight subtractive libraries were constructed using apical meristem induced or not induced for two contrasting species: Solanum lycopersicum cv. Micro-Tom and Solanum pimpinellifolium. Several cDNAs were identified and among these, were selected two cDNAs: one homologous cDNA to cyclophilin (LeCYP1) and the other to Auxin repressed protein (ARP). It has observed that LeCYP1 and ARP genes are important in the developmental process to plants. In silico analysis, were used several databases with the exclusion criterion E-value <1.0x10-15. As a result, conservation was observed for proteins analyzed by means of multiple alignments and the presence of functional domains. Then, overexpression cassettes were constructed for the ARP cDNA in sense and antisense orientations. For this step, it was used the CaMV35S promoter. The cDNA orientation (sense or antisense) in relation to the promoter was determined by restriction enzymes and sequencing. Then, this cassette was transferred to binary vector pZP211 and these cassettes were transferred into Agrobacterium tumefaciens LBA4404. S. lycopersicum cv. Micro-Tom (MT) and MT-Rg1 plants were transformed. In addition, seedlings were subjected to hormone treatments using a synthetic auxin (- naphthalene acetic acid) and cyclosporin A (cyclophilin inhibitor) treatments and it was found that the hormone treatment there were changes in development of lateral roots pattern, probably related to decreases in auxin signaling caused by reduction of LeCYP1 in MT-dgt plants while cyclosporin A treatments, there was a slight delay in flowering in cv. MT plants. Furthermore, assay with real-time PCR (RT-qPCR) were done for expression level analysis from LeCYP1 and ARP in order to functionally characterize these sequences in tomato plants.

Primary cementing is one of the main operations in well drilling responsible for the mechanical stability and zonal isolation during the production of oil. However, the cement sheath is constantly under mechanical stresses and temperature variations caused by the recovery of heavy oil. In order to minimize fracture and wear of the cement sheath, new admixtures are developed to improve the properties of Portland cement slurries and avoid environmental contamination caused by leaking gas and oil. Polymers with the ability to form polymeric films are candidates to improve the properties of hardened cement slurries, especially their fracture energy. The present study aimed at evaluating the effect of the addition of a chitosan suspension on cement slurries in order to improve the properties of the cement and increase its performance on heavy oil recovery. Chitosan was dissolved in acetic ac id (0.25 M and 2 M) and added to the formulation of the slurries in different concentrations. SEM analyses confirmed the formation of polymeric films in the cementitious matrix. Strength tests showed higher fracture energy compared to slurries without the addition of chitosan. The formation of the polymeric films also reduced the permeability of the slurry. Therefore, chitosan suspensions can be potentially used as cementing admixtures for heavy oil well applications

Waterflooding is a technique largely applied in the oil industry. The injected water displaces oil to the producer wells and avoid reservoir pressure decline. However, suspended particles in the injected water may cause plugging of pore throats causing formation damage (permeability reduction) and injectivity decline during waterflooding. When injectivity decline occurs it is necessary to increase the injection pressure in order to maintain water flow injection. Therefore, a reliable prediction of injectivity decline is essential in waterflooding projects. In this dissertation, a simulator based on the traditional porous medium filtration model (including deep bed filtration and external filter cake formation) was developed and applied to predict injectivity decline in perforated wells (this prediction was made from history data). Experimental modeling and injectivity decline in open-hole wells is also discussed. The injectivity of modeling showed good agreement with field data, which can be used to support plan stimulation injection wells

The flowering is a physiological process that it is vital for plants. This physiological process has been well studied in the plant model Arabidopsis, but in sugarcane this process is not well known. The transition of the shoot apical meristem from vegetative to flowering is a critical factor for plant development. At Brazil northeastern region, the transition to flowering in sugarcane has an important effect as it may reduce up to 60% its production. This is a consequence of the sugar translocation from stalks to the shoot apical meristem which is necessary during the flowering process. Therefore, the aim of this work was to explore and analyze cDNAs previously identified using subtractive cDNA libraries. The results showed that these cDNAs showed differential expression profile in varieties of sugarcane (early x late flowering). The in silico analysis suggested that these cDNAs had homology to calmodulin, NAC transcription factor and phosphatidylinositol, a SEC14, which were described in the literature as having a role in the process of floral development. To better understand the role of the cDNA homologous to calmodulin, tobacco plants were transformed with overexpression cassettes in sense and antissense orientation. Plants overexpressing the cassette in sense orientation did not flowered, while plants overexpressing the cassette in the antissense orientation produced flowers. The data obtained in this study suggested the possible role from CAM sequence, SEC14 and NAC in the induction/floral development pathway in sugarcane, this is the first study in order to analyze these genes in the sugarcane flowering process.

The preeclampsia is a disease that evolves to high death rate for the mother and for the fetus. The incidence of this disease in the world is variable and there are no data of this disturb in the Brazilian population. This paper had the objective to determine the incidence and risk factors for development of hypertensive disorders of pregnancy in a neighborhood in Natal, RN, Brazil, taking place a prospective study, cohort type, with the objective of evaluating the entire pregnancy of 242 women that got pregnant between 2004-2007. The incidence of hypertensive disorders was of 17%, while the incidence of preeclampsia was of 13.8%. The age average of women that developed the hypertensive disorders was of 27.4 years (SD±.9), whilst those that developed preeclampsia was of 26.6 (SD ±7.8) years and the normotensive was of 23.9 (SD±5.8) (p=0.002). It is noted a significant increase of the hypertensive disorder with age (p=0.0265). The gestational age for those who developed preeclampsia was lower than the women that developed normotensive pregnancy (p=0.0002). The body mass index (BMI) of the group of women that developed the hypertensive disorder was of 25.8 (SD±3.9), significantly higher than the group of normotensive women with 23.5 (SD±3.7) (p=0.02). The levels of triglycerides and cholesterol tended to be higher on women with preeclampsia than on normotensive, p=0.0502 and p=0.0566, respectively. Six (6) women presented with severe preeclampsia and one (1) developed HELLP Syndrome. The resolution of the pregnancy was performed by cesarean section in 70% of women that developed hypertensive disorders, whilst the normotensive was of 23.6% (p<0.0001). A subgroup of the studied subjects was reassessed one year after labor, revealing that 50% of the patients were still hypertensive. There were no larger complications nor mother death during labor. The incidence of hypertensive disorders are above the levels noted in other studies and 30% of the women were within the poles of greater risk for the hypertensive disorders; the elevated BMI in the beginning of the pregnancy is a risk factor for hypertensive disorder. The risk of severe complication in preeclampsia is high, with imminence of eclampsia occurring in 20.1% of women who developed hypertensive disorder of pregnancy. The adequate prenatal care and the opportune labor assistance may minimize the complications of the pregnancy hypertension and avoid mother death, although the risk of women remaining hypertensive is elevated

The proposal of this study was to work with women in the politics, focusing on their trajectories, biographies and speeches, to catch the meanings given by themselves to their insertion in the political field. The privileged instrument of research was the autobiographical narratives of fifteen women who, in Paraíba, had participated of the electoral processes and the life partisan politics in the period from 1998 to 2008, in the state and federal scopes. This permitted us to search the dimension of their lived expericence, to understand the trajectories and the processes of autonomation of the women, in the politics. Moreover, a quantitative mapping of the feminine presence in the processes was made electoral politicians in a wider context. In a similar way, two surveys had been carried throughout the research, among others aspects, to understand that image voters and politicians they construct concerning the feminine participation in this field. These instruments were important not to lose of all the social view where these lives were developed, the places from which these women speak and locate and the social meanings originated from this participation. The research aimed to establish dialogues between knowing and fields of discipline, beyond the dichotomy of actor/structure, preventing generalizations that ignore the plurality of the individuals, to reveal some aspects of the complex and contradictory processes that involve their participation in the political field. At last, it is tried to show that, although the frequent accusations of autonomy lack, when establishing relations in the public space, the women, as all subjects, can reflect about themselves, the motives of their thoughts and their actions escaping from the servitude of the repetition and avoid being only product of the institution that formed them (CASTORIADIS, 1992, p.140-141)

In this master s thesis I intend to carry out an interpretation of Michel Foucault s thought that points out the relations and theoretical, conceptual and thematic consequences with sociology in his work and theoretical propositions. For my argumentation and analysis I take as a base a specific part of his thought: the problem of domination in modern societies in the genealogic texts in the decade of 1970. It s about to identify how Foucault does his analysis of the relations of domination and the use of the power with the objective to suggest and point out his contribution to sociological analysis of domination. I will discuss the foucaultian program of the study of domination from four units of analysis: person constitution, knowledge, power and truth. The structure and division of the chapters will follow the specific and detailed study of each of those units of analysis, prioritizing their theoretical sense and consequences to the sociology. Thus, in the first chapter, I will highlight a little more the relations of affinity and the convergences between Foucault and the sociology in a way to offer more elements to justify the general objectives that this work intends to achieve. In the second chapter, I will analyze the subject of domination in Foucault s thought, discussing his basic presuppositions and its intrinsic relation with the heart of the foucaultian philosophical project, the person constitution. In turn, in the third and fourth chapter, I will discuss the interdependence between knowledge and power as an essential and opaque dimension of the ways of modern domination. In the fifth chapter, I will analyze the relation between domination and the truth discourse production

The present study aimed to understand how and to what extent the electronic forró, currently hegemonic in the music market in the state of Rio Grande do Norte, establishes and maintains relations of domination in the social contexts in which it is produced, transmitted and received. Based, in significant form-content, on the writings of the first generation of theorists of the so-called Frankfurt School (Critical Theory), particularly with Theodor W. Adorno, and systematically using the contributions of the Cultural Studies (from the Centre for Contemporary Cultural Studies of Birmingham) and of the sociology of Pierre Bourdieu, this study aimed to perform, in the fertile intersection of these references, a critical possibility of interpretation of the electronic forró predominantly spread in the state of Rio Grande do Norte. To this end, aiming at a better apprehension of the so-called capital circuits/culture circuits , this study resulted from a qualitative investment of research, based on structured interviews with musicians, entrepreneurs of the sector and music consumers, as well as on the analysis of the themes contained in the official discography of the electronic forró band called Garota Safada (Shameless Girl). As a general empirical conclusion, it was possible to infer that far from the significant presence of domination or mere prevalence of oppositions, there is a relational pluralism of forms of domination and ways of resistances present in the production and consumption of electronic forró, regardless of gender, age, income, education or place of residence. However, the artifices of the cultural industry has been shown to be efficient: from large-scale businessmen to small producers enabled by the so-called open markets . The currentness of the concept of cultural industry is based on the idea that its products are offered systematically (the systematic insistence of everything to everyone) and on the notion that its production primarily meets the administrative criteria of control over the effects on the receiver (capacity of prescription of desires). Thus, the Adornian reflection on the pseudo-individualization leads to the inference that even in some of the most apparent ways of negotiation and/or refusal regarding the consumption of forró, certain behaviors of the cultural industry still prevail both in the very (re)interpretation of the forró and in the choice of other music genres also standardized, rationalized and massified. Therefore, despite the absence of cause-effect relation and the recognition of the popular capacity of re-elaboration and contestation of the media consumption, some world views prevailing in relation to the electronic forró establish or, at least, support some hegemonic ideologies, especially those concerning the life style, consumption and genre relations (fun by all means). Therefore, due the massification of certain songs, some ways of dissemination of values, beliefs and feelings are potentially experienced from the electronic forró. So, it is presumable that in the current advance of the process of semiformation (Halbbildung), the habitus of a part of the youth from the state of Rio Grande do Norte reinforces and is reinforced by the centrality of the trinomial fun, love and sex present in the songs, emphasized in some constructive practices of sense and in certain flows of social significance

This work has proposed to relate the experience product of a pedagogical intervention, performed in a public institution of teaching situated in this capital. It had as objective to validade the applying of a teaching module of geometry, more specifically about the conceptions of perimeter and área in the second cycle of fundamental teaching. This dissertation has presented the problematic which involves the teaching of geometry in different contexts. It has adopted the broach of the radical constructivism while methodological theoretical referencial through which it has tried to explain the phenomena that involves the teaching and the apprenticeship. It appropriates Jean s Piaget contributions related to the development stages, while referencial that will dialogue in the search by sense and comprehension of the geometric apprenticeship process and it runs over Richard s Skemp (1980) theory in order to explicit the student s apprenticeship according to the levels of instrumental comprehesion and relacional comprehension . The research has presented datum related to initial diagnosis evaluantion, the pedagogical intervention and analysis of the activities and students perfomance displaying still the results of the final evaluation. According to the results got, we could check the students group growth front to the acquisition of the concepts of perimeter and área in comparison with the previous knowledges presented in the initial diagnosis evoluation of the students participants of the research. We have concluded evaluating the objectives of the research, connecting the strategies and reasoning employed by the students in order to resolve the questions and then to reach the objectives proposed by the teaching module. We have presented still the main obstacles to the apprenticeship of such concepts

In Reading Television: Limits of the course TV in the School and the Challenges of Today in Sergipe , we had as objective to detect that type of critical reading of the cultural texts produced by the television, professionals of the education of the public net of the basic and average education of the state of Sergipe that all had concluded its 3 (three) modules carries through. We were effectively tutorial of the first edition of this course of extension in the distance and witness some inconsistencies in its application, moment where the instigated investigation appeared: ahead of the current necessity of if understanding with a critical sense, the paper that plays it measured them in orchestration of the globalizado world, that type of critical reading of the audiovisual language is capable to carry through a professional of the education that participated of a course of this nature? Beginning with documental analysys and qualitative metodology we try to analyse in four chapters, since the origins and motivations of this course, to the opinions of 10 (ten) former course students about the approaches of the same thematic subject by two different television new programs, without missing the opinions of the tutors about the conditions in which were made 4 (four) consecutive editions of the course in Sergipe nor the concrete relationships estabilished by the former course students and the audiovisual on their everyday routine both at home and at work. We conclude that the reading made by the former course students is based on common sense and then not satisfactory to the requirements of this task nowadays, and at the same time we point out that the course failed, for it presented severe issues in terms of management and operations in its practical application to distance, by priorizing quantity over quality, by linking itself to a deficient technical structure, by not beholding the diosyncrasies nor the fundamental videos the teachers have access everyday and that it all had direct relation with the attachment of this course to a verticalized policy of technologization of brazilian education.

The present study had the objective to identify to the Social Representations of the professionals of medicine and nursing superior level of the Program Health of the Family concerning the assistance for the gestation. The research was qualitative under the optics of the Theory of the Social Representations of Serge Moscovici, of the Central Nucleus of Jean-Claude Abric and of the Analysis of Content of Laurence Bardin. We worked with the following instruments for the collection of data: Questionnaires, with social-demographic data; Free association of Words, with the inductive terms Pregnancy, Assistance for Gestation and Care; Production of mental image and half-structuralized Interview, with the following question: What does the assistance for the gestation represent for you? . We interviewed all the professionals of nursing and medicine of the Program Health of the Family in the city of Santa Cruz /RN (ten for each profession) in the period of February and March of 2007. From the analysis of the social-demographics data, we respectively identified the following percentages for nursing and medicine: the feminine sex for nursing predominated (90%); the age between 24 and 33 (70 and 60%); the religion catholic (80 and 50%) and 50% of the two groups has up to two years of formation and work in the score of the research. The analysis of the others instruments resulted in two categories: Institutionalized vision and Vision of the Common-sense. In the free association of words, the category institutionalized vision is configured as Central Nucleus and of the common sense one as nucleus Peripheral, demonstrating that the Social Representations of the assistance for the gestation attendance are in the universes consensual. In the mental images, we identified to this same construction. In the content of the interviews, the institutionalized vision is permeated by the responsibility of making and the availability of having - assistance for the gestation is recommended by the Health department and necessary genders - while the vision of the common-sense can be represented by the category sort, whose role of professionals of the assistance for the gestation is to strengthen the responsibility for the woman of a maternity socially constructed. In short, the analyzed speeches reflect that, to the knowledge acquired in the academy, are incorporated in the knowledge of the daily professional, and conducted by popular myths. Medicine and nursing recognize the importance of the attendance in such a way for the chance to educate the women for the maternity as for the possibility to prevent complications, but in its speeches they had excluded from this process the masculine figure. We conclude that the meaning of the inductive term take care, part of the common-sense and is incorporated the institutionalized speech to humanize the assistance. However, the pregnancy ceases from being seen in its natural biological direction and starts to be analyzed as a moment of fragility and predisposition the illnesses. Finally, the social nursing and the central nucleus representations for the assistance in gestation for medicine is anchored in the speeches institutionalized and of the common-sense, reflecting the concern in establishing a humanized assistance with quality

This work is inserted to Applied Linguistic studies, concerned to the understanding that language is a social practice, bringing a qualitative research, discussing essential aspects that involve the subject and his/her discursive practice: signification and valuation. Due to this, we have elected as subject study, the sense and values attributed to the verbs make out and date searched on the articles written in the Vestibular 2005 process promoted by the Universidade Federal do Rio Grande do Norte (UFRN), that had the following instruction: In a relationship, is it better make out , just date , or, both, make out and date ? This research is based on the Circle of Bakhtin s dialogic theory, as well as in the notions of instability in the affective relationships nowadays and in the individualization and multiplicity of contemporaneous subjectivity. Those papers are important to analyze the meaning and values that the verbs make out and date present, nowadays, as expressions of an affective relationship and how this situation can interfere in the positions of subjectivity in a formal instance as a vestibular. Those textual productions reflect those relationships, confronting temporary ones, whose discuss is marked, in general, by social voices that evaluate to make out negatively and to date positively

This research, part of Applied Linguistics field, aims to analyze the language of a school blog, developed with the participation of students, as a work based on the conception of multiliteracies, focusing on the construction of different meanings. The research is carried on from the building and maintenance of a school blog, the Ieceblog, with students of Ensino Fundamental II, since 2008, in a private school in Natal-RN. The investigation of the language produced on a school blog is justified due to the interactive conceptions of writing and reading on the virtual environment. Given the fact that new technologies are a reality in the schools opened to the practices of multiliteracies, it is assumed that text, image, video, audio, non-graphic signs and hypertext intensifies the produced interaction, in which the students become real authors. In this perspective, some voices belonging to the statements that are formed through the posts and comments chosen to the analyses and reflection on the blog space as locus of productions of senses inserted in the school and the world environment, as well as for the identification of the language resources used to intensify the senses that emerge from it. From the view of dialogism conceptualized by Bakhtin Circle, the qualitative interpretive-research deepens the experience of a school blog focusing on digital language in line with the vision of digital literacy. From the blog posts, a corpus that promote the exposure of different manifestations of language in the design of digital multiliteracies is elected. Thereby, the method used was the dialogical analysis of speech based on Bakhtin s studies and the Circle. The corpus was taken from the blog s posts in order to point up the different language manifestations in the following categories: (i) mood reinforced by the mockery, (ii) search for compliance with school sphere, (iii) conflicting social values and consistent complicity between sense and verbal imagery, and finally (iv) social practices that take place from and through the discursive genre. The study points to the tension between the active voices in several directions, revealing the distorted unit of posts which, under the analytical observation raises multiple meanings in a responsive manner. The analysis of the dialogue interaction in which intersperses the digital one becomes more apparent that the multiliteracies events that are mediated by language in addition to structure of the language and makes us rethink the students

This study approach the Jorge Luis Borges s prose of fiction under the perspective of mimesis and the self-reflexivity. The hypothesis is that the Aleph is a central symbol of the Borges s fictional universe. The rewriting and the retake of this symbol along of his work entail to a reflection about the possibilities and the limits of mimesis. This study is divided in three parts which contain two chapters. The first part Bibliographic revision and conceptual fundaments of inquiry discuss the critical fortune of author (Chapter 1) and the concepts that will give sustentation to the inquiry (Chapter 2). The second part About the Borges s aesthetic project sketch out the literary project defended by Borges that is his conception of the literature and his ideological matrix (Chapter 3) beside his anti-psychologism and his nostalgia of epos (Chapter 4). The third and last part is entitled The Aleph and his doubles. In the chapter 5 this study analyses the short story El Aleph and consider its centrality on the Borges s work. The argument that is on this short story Borges elaborates a reflection about mimesis. In the chapter 6, on the same hand, four short stories will be analysed: Funes el memorioso ; El Libro de Arena ; El evangelio según Marcos and Del rigor en la ciencia . The conclusion that is the Borges s literature is self-awake of its process as such demonstrate its parodic sense and its bookish origin. Hence, the Borges s literature overlapping the mimetic crisis of language and challenge the limits between fiction and reality. However, it doesn t surrender to the nihilist perspective that is closing of literature to the world
