With an eye to academia or vocation? A draft to a research plan

There is a profound need to increase the quality and status of vocational education and train-ing (VET) and vocational education and training education – Teacher training (VTE-TT). As a consequence of several reforms the requirements of academic achievements in these different education systems are distinctly higher than before. These high ambitions cause problems and the actors in school and teacher education has got new challenges. Furthermore, vocational education teachers are supposed to prepare their pupils both to a pro-fessional career and to future academic studies. Accordingly, Vocational Education Teacher Trainers are supposed to prepare their students both to a career as vocational teachers and for further academic studies. This makes imprints in the field of VET and VTE-TT. The aim of this paper is to present a coming study about how actors in VET and VTE-TT think and act in relation to their changed assignment.

Predator Survival Tactics and Use of Habitat Cover in Rana Catesbeiana.

Predator-prey relationships are an important aspect of the natural world, and, because of its relevance to survival and natural selection, is an interesting relationship to study. In amphibian larvae, level of activity and landscape use are often what determines the survival as prey. I studied the anti-predator behavior of the North American bullfrog (Rana catesbeiana) tadpoles when presented with dragonfly (Aeshna) larvae, a known predator of tadpoles. Tadpoles were acclimated to four different habitats with varying degrees of habitat cover, and were transferred to a new habitat with a degree of cover equal to one of the acclimation tanks. A restrained predator, and thus its chemical cue, was introduced, and the behavior, particularly the use of the habitat cover to hide from the perceived risk of predation was observed. A significantly higher frequency of inactivity was found in tank I than in II and III, and inactivity followed a general trend of decreasing with increasing habitat cover. Difference in tank cover was not found to have a significant effect on swimming behavior, but did have a significant effect on hiding behavior, which increased with higher availability. Foraging decreased significantly with the addition of a predator, but did not vary significantly with different levels of cover. Hiding behavior and reducing conspicuous behaviors (like foraging) are probably the behaviors that afford the tadpole the most success at eluding a predator in their natural environment.

As escolhas das carreiras minimizam o impacto da política de cotas? O caso do estado do Rio de Janeiro

Esta pesquisa busca verificar se a política de cotas, incluída na legislação federal brasileira por meio da Lei nº 12.771 de 2012, ao tornar obrigatória a reserva de vagas no ensino superior numa combinação de cor/raça, renda e origem em rede pública de ensino médio, tem caminhado para alcançar seu objetivo de forma a minimizar as dívidas racial e social brasileiras, causadas, entre outras, pela escravidão que por décadas se perpetuou no país. Para isso a pesquisa focou na escolha das carreiras dos estudantes cotistas e não cotistas de uma forma geral, além de por sexo e turno. Buscará evidenciar a hipótese de que o público-alvo da política de cotas ao escolher carreiras menos prestigiadas ou com menor retorno financeiro, finda por minimizar o impacto da mesma e sugere que política complementar seria necessária. Para classificar e agrupar as carreiras, o trabalho utilizou a base de dados do Instituto Brasileiro de Geografia e Estatística - IBGE que lista as carreiras pela remuneração média percebida. Após contextualização da desigualdade racial e social, da educação como promotora do desenvolvimento econômico e social, das experiências americana e brasileira com ações afirmativas, da exposição da legislação que dispõe sobre o tema e de estudos já realizados, e da importância da avaliação das políticas públicas, são analisados os dados do Censo Escolar do Ensino Superior, do ano de 2013, do Instituto Nacional de Estudos e Pesquisas Anísio Teixeira – Inep, no que tange a escolha de carreira dos cotistas e não cotistas, além de por sexo e turno. A abrangência da pesquisa se restringiu às universidades, centros e institutos públicos situados no estado do Rio de Janeiro que, em diferentes graus e épocas já adotaram a política de cotas, a fim de verificar a hipótese. Ao final a pesquisa demonstra que o modelo de regressão que inclui as IES e o tempo de vigência da política se mostrou estatisticamente significativo sinalizando a forte influência das IES e do tempo sobre a razão de cotista e que, ao contrário do que se pensava, os cotistas escolhem as carreiras mais bem remuneradas ou de mais prestígio. Além disso, demonstra que o sexo feminino, da mesma forma que os estudantes de turno noturno, de uma forma geral, cotistas e não cotistas, optam por carreiras menos remuneradas indicando a necessidade de política complementar que: fomente a participação do sexo feminino nessas carreiras, avalie as carreiras e vagas oferecidas no turno noturno e corrija distorções que ampliem o leque de possibilidades para os alunos de ensino superior.

Defining student participation and empowerment in higher education

Customer participation has been studied for decades; however, it gained a postmodern perspective around the year 2000. Customers have become co-creators of personalized experiences, moving from the audience to the stage. In the educational context, students must take responsibility for their learning process and participate in the production of the service. This changing is providing opportunities and challenges for higher education institutions (HEIs) to redefine their relationship with stakeholders, especially with students. This study is based on the service dominant logic (SDL) perspective because students are assumed to take the role of co-creators of knowledge in the educational setting. The research uses adapted frameworks and concepts applied in organizational, knowledge-intensive business services (KIBS) and also medical studies to advance the understanding of value co-creation in the HEI context. The current study addresses a lack of research in the higher education context focusing on defining students’ participation and students’ empowerment in higher education context. An empirical investigation was developed with traditional schools in Brazil. This investigation allowed the description of the constructs in the specific context. The description of student participation in HEIs context reflects the relevance of three dimensions – information sharing, personal interaction and responsible behavior. In the Brazilian context, responsible behavior is the weakest dimension in the construct, because the responsibilities are unbalanced between students and professors. The main reasons identified for this unbalanced relation were cultural issues and local regulation. Student empowerment was described as composed by four dimensions – meaningfulness, competence, impact and choice; however, one of them – choice – was identified as the weakest dimension, facing cultural and bureaucratic barriers for implementation in the Brazilian educational context. Moreover, interviewees spontaneously cited the idea of trust in the faculty as an important antecedent of student participation that must be considered when analyzing student participation and empowerment mechanisms. An additional contribution was the proposal of a theory-based framework for understanding the service dominant logic perspective in the HEI context, in which student participation and student empowerment were explored as mechanisms leading to positive student behavior toward institution.

Democratização do acesso ao ensino superior: os cursos de graduação à distância na UFRN

This thesis pursuits to contextualize the theoretical debate between the implementation of public education policy of the Federal Government focused in a distance learning and legal foundations for its enforcement, in order to raise questions and comments on the topic in question. Its importance is back to provide scientific input and can offer to the academy, particularly in the UFRN, and elements of society to question and rethink the complex relationship between the socio-economic and geographic access to higher education. It consists of a descriptive study on the institutionalization of distance education in UFRN as a mechanism for expanding access to higher education, for both, the research seeks to understand if the distance undergraduate courses offered by the UAB system and implemented at UFRN, promote expanding access to higher education, as it is during implementation that the rules, routines and social processes are converted from intentions to action. The discussion of this study lasted between two opposing views of Implementation models: Top-down and Bottom-up. It is worth noting that the documents PNE, PDE and programs and UAB MEETING reflect positively in improving the educational level of the population of the country It is a qualitative study, using the means Bibliographic, Document and Field Study, where they were performed 04 (four) in 2010 interviews with the management framework SEDIS / UAB in UFRN. The data were analyzed and addressed through techniques: Document Analysis and Content Analysis. The results show that the process of implementation of distance education at UFRN is in progress. According to our results, the research objective is achieved, but there was a need to rethink the conditions of the infrastructure of poles, the structure of the academic calendar, the management of the SEDIS UFRN, regarding the expansion of existing vacancies and the supply of new courses by the need for a redesign as the Secretariat's ability to hold the offerings of undergraduate courses offered by the Federal Government to be implemented in the institution. It was also found that levels of evasion still presents a challenge to the teaching model. Given the context, we concluded that the greatest contribution of UAB and consequently UFRN by distance learning for undergraduate courses (Bachelor in Mathematics, Physics, Chemistry, Geography and Biological Sciences, beyond the bachelor's degrees in Business and Public Administration ) is related to increasing the number of vacancies and accessibility of a population that was previously deprived of access to university

Benthic response to upwelling events off the SE Brazilian coast

The main aim of the present study was to evaluate and compare temporal responses of the benthos in 2 continental shelf areas (Cabo Frio and Ubatuba) off the SE Brazilian coast. In Cabo Frio (23 degrees S, 42 degrees W), the western boundary coastal upwelling of the South Atlantic Central Water (SACW) enhances primary productivity, potentially increasing food supply to the benthic communities via sinking of particulate organic carbon (POC). In contrast, POC fluxes in Ubatuba (23 degrees S, 45 degrees W) are expected to be comparatively lower because SACW remains subsurface. We analyzed the temporal and spatial input of phytodetritus (concentration of chlorophyll a in sediments) and the benthic microbial biomass (estimated by ATP-based carbon content in sediments). Median surface chlorophyll concentration was computed for all daily available SeaWiFS images (from 2001 and 2002) to follow chlorophyll a inputs. All parameters used to investigate benthic responses in the study areas showed consistently higher values in Cabo Frio than in Ubatuba. The results showed that benthic response to upwelling may last months, fueling the microbial communities in the Cabo Frio region.

Annual pattern of plasma melatonin and progesterone concentrations in hair and wool ewe lambs kept under natural photoperiod at lower latitudes in the southern hemisphere

To study the annual pattern of plasma melatonin and progesterone concentrations in hair [Santa Ines (SI)] and wool [Romney Marsh (RM) and Suffolk (SU)] ewe lambs kept under natural photoperiods at 21 degrees 59'S, 12 ewe lambs (four/breed) were used. For melatonin, blood samples were collected monthly throughout the year at the onset (17:00, 19:00 and 21:00 hr) and end (04:00, 06:00 and 08:00 hr) of the night, and for progesterone the samples were collected in the morning, two to three times a week throughout the year. Plasma melatonin concentrations at different times of the day changed according to the season. In diurnal periods (17:00 and 8:00 hr) no seasonal differences were observed but they became evident in the nocturnal intervals (21:00 and 4:00 hr) and transitional night-day (6:00 hr) times. The patterns of melatonin secretion were higher in winter and autumn than in spring and summer. The patterns of plasma progesterone secretion were affected by interaction between breed and season. There was no seasonal variation in plasma progesterone concentrations for SI females. The progesterone pattern for RM and SU females varied with season. The plasma levels were higher in autumn and winter than in spring and summer. At 21 degrees 59'S hair and wool ewe lambs showed the same annual pattern of plasma melatonin concentration while the annual progesterone profiles were quite different. For SI females this pattern was constant along all seasons and for RM and SU females this pattern was higher during autumn and winter than spring and summer.

As coisas estão no (meu) mundo, só que eu preciso aprender. Autobiografia, reflexividade e formação em Educação Nutricional

This paper gives clues for the educative action in nutrition subjects. It deals about the professors experiences deployments lived in 2003 e 2004, both in Nutrition undergraduate course of the Federal University of the Rio Grande do Norte (UFRN), in Nutrition Education and Supervised Internship in Social Nutrition academic disciplines, as well as in the II Update Course in Nutrition Practices for Health Basic Care , offered to the supervisors nutritionists of internship, in this same department, being able to be characterized as an action-research, with interventionism purpose. The study stands out the importance of a new point of view about the nutritionist formation to overcome the limits imposed by the scientism, and the adoption of a complex and reflexive reference about the educational practice in this area. The corpus is made up by 81 undergraduate students alimentary autobiography (source of generating subjects for interventions with the nutritionists), 17 questionnaires and 05 interviews, being 03 of them biography (the start up for an initial dialogue with the nutritionists). The data found and the professors experiences allied to a theoretic reference, by the light of the education proposals for the XXI century were used as establishment elements for the proposition of five guidance axles used to build a complex and reflexive nutrition education, which are: 1) Take the cookery and the culture of eating together as significant elements for the human being integral formation; 2) Conceive the religion manifestations associated to feeding process as relevant elements of the human food culture; 3) Discuss the rupture nature/culture aiming the preservation of live in earth; 4) Search for the overcoming of the identity conflicts by a higher inclosing conscience degrees of being part of this process. 5) Face the limits of fragmented formation. The presented thesis stands that the autobiography method, allied to the freirean pedagogy and to a complex reference, could be taken as an important tool to the health educative subjects, contributing to the formation of reflective individuals able to transform themselves and the world.

Involvement of serotoninergic receptors in the anteroventral preoptic region on hypoxia-induced hypothermia

Hypoxia causes a regulated decrease in body temperature (Tb). There is circumstantial evidence that the neurotransmitter serotonin (5-HT) in the anteroventral preoptic region (AVPO) mediates this response. However, which 5-HT receptor(s) is (are) involved in this response has not been assessed. Thus, we investigated the participation of the 5-HT receptors (5-HT(1), 5-HT(2), and 5-HT(7)) in the AVPO in hypoxic hypothermia. To this end, Tb of conscious Wistar rats was monitored by biotelemetry before and after intra-AVPO microinjection of methysergide (a 5-HT(1) and 5-HT(2) receptor antagonist, 0.2 and 2 mu g/100 nL), WAY-100635 (a 5-HT(1A) receptor antagonist, 0.3 and 3 mu g/100 nL), and SB-269970 (a 5-HT(7) receptor antagonist, 0.4 and 4 mu/100 nL), followed by 60 min of hypoxia exposure (7% O(2)). During the experiments, the mean chamber temperature was 24.6 +/- 0.7 degrees C (mean +/- SE) and the mean room temperature was 23.5 +/- 0.8 degrees C (mean +/- SE). Intra-AVPO microinjection of vehicle or 5-HT antagonists did not change Tb during normoxic conditions. Exposure of rats to 7% of inspired oxygen evoked typical hypoxia-induced hypothermia after vehicle microinjection, which was not affected by both doses of methysergide. However, WAY-100635 and SB-269970 treatment attenuated the drop in Tb in response to hypoxia. The effect was more pronounced with the 5-HT7 antagonist since both doses (0.4 and 4 mu g/0.1 mu L) were capable of attenuating the hypothermic response. As to the 5-HT(1A) antagonist, the attenuation of hypoxia-induced hypothermia was only observed at the higher dose. Therefore, the present results are consistent with the notion that 5-HT acts on both 5-HT(1A) and 5-HT7 receptors in the AVPO to induce hypothermia, during hypoxia.

Environmental temperature and cloacal and surface temperatures of broiler chicks in first week post-hatch

Adequate environmental temperature during the brooding period is very important to future broiler performance. Thus, the objective of this study was to investigate the extent to which environmental temperature affects the body weight and cloacal and surface (back, head, wing, and shank) temperatures. The study also investigated the sensible heat loss by radiation of broiler chicks reared at three environmental temperatures (35, 25, and 20 degrees C) up to 7 days of life. The results showed that chicks raised at low environmental temperature (20 degrees C) had lower body weight at 7 days of age. Birds kept at 20 degrees C also had significantly lower cloacal and surface temperatures than did other birds. The most marked difference was seen in the shanks. These findings revealed that body weight declined in chicks reared at 20 degrees C, and radiant heat loss (W) was nine times higher than for the birds kept at 35 degrees C at 7 days of age.

Ser bacharel e professor: sentidos e relações entre o bacharelado e a docência universitária

The need to research about meanings and relationships between individuals with Bachelor s degrees and Teaching can be considered an exercise capable of aiding in the comprehension of the very performance of the Bachelor as teacher. The guiding question of this study asks: what relationships are established by Bachelors, who are teachers, between their professional education and their performance as a teacher? My objective is to understand the meanings attributed by the Bachelor teachers to teaching at the university level, seeking indicators about the relationships established by them, between their professional education and being a teacher. For this, the methodology used was the Comprehensive Interview, which permits, through the individual s oral discourse, the interpretation of meanings and values expressed by the teachers about their actions. The research is done through oral discourse collected in interviews and from these I analyze the elements that are revealed, and those which help me in the development of this object of study. I understand that the contribution about the possibilities of action and continued education for Bachelors who act as instructors in Higher Education is increasingly necessary, through research, because through continuing education teachers can revisit their actions and reformulate meanings they attribute to teaching as a profession. I consider the debate about meanings about teaching and the relationships with the initial education is not only necessary in the investigation of the Bachelors who act as professors, but also the credentialed teachers, because the teacher s sense of identity and their professional development is constructed through a historical process and in relation to the alternative positioning in the contexts of which they are a part

Violência contra a mulher : estudo de caso em uma instituição de ensino

The study research case with a quantitative approach and prospective data, carried out between December 2010 and February 2011 with the aim of identifying the profile of women in the study, to characterize the acts of violence in the type, frequency, location occurrence and aggressor, analyze the steps taken after the occurrence of acts of violence and the main consequences on the victims. The population consisted of 285 workers in a tertiary institution in Rio Grande do Norte. The results showed that 99 (34.74%) have between 51 to 60 years of age, 78 (27.37%) of 41 to 50 and 62 (21.75%) between 20 and 30 years, are considered color white, 162 (56.84%) have completed higher education, 171 (60.00%) and of these 97 (56.73%) reported having some post-graduate degrees, are married, 141 (49.47%) and have from zero to one child, 148 (51.93%) reside in the south of the city of Natal, 146 (51.23%) have a monthly income of three to five minimum wages, 171 (60.00%) and are mostly in the Technical Administrative Sciences 152 (53.33%), 77 (27.02%) reported having experienced violence, 60 (62.50%) episodes of verbal aggression, 26 (27.08%) of bullying , 05 (5.21%) of physical abuse and 05 (5.21%) sexual harassment; 05 (100.00%) assaults were made by the spouse or partner of the victims and co-workers is another profession were responsible for 18 (30.00%) verbal aggression, 15 (57.69%) bullying and 03 (60.00%) sexual harassment, 02 (40.00%) of victims of physical aggression and 18 (30.00 %) of verbal abused only once, 10 (38.46%) of bullying and 02 (40.00%) of sexual harassment experienced four or more times 05 (100.00%) assaults occurred at domestic and work stood out with 36 (60.00%), verbal abuse, 22 (84.62%), moral harassment and 04 (80.00%) sexual harassment, 35 (36.46%) told colleagues work and 31 (32.29%) for family and friends in 75 (78.13%) cases there was no intervention, 07 (7.29) were unable to respond if something had been done and 14 (14.58% ) have been reported intervention of these, 09 (64.29%) were taken by the heads of the victims, 26 (32.10%) did not notify the fact on the ground that no action would be taken, 62 (80.52%) felt stress , 5 (1.76%) of women turned away from work after the episode of violence, accounting for 198 days of absenteeism. It is concluded that there is a high rate of violence against women, even when they have a good socioeconomic status, and in this sense is important to establish bases of new proposals for improving control of cases of health professionals, especially nurses, to approach patients with a more investigative, and that by identifying a case of violence, be instructed about the paths to be followed for notification while providing psychological support to victims.

Germinação de sementes de Dypsis decaryi(Jum.) Beentje & J. Dransf. (Arecaceae)

Dypsis decaryi (Jum.) Beentje & J. Dransf. is an important palm with ornamental commercial value. Although it reproduces sexually, there are no data available as far as what are the factors that affect this species seed germination. The purpose of this work is to study the potential effects of temperature and substrate in Dypsis decaryi seed germination. The research framework is based on randomization, using a 6 X 2 factorial schema (six different temperatures, 25 degrees C, 30 degrees C, 35 degrees C, 20-30 degrees C, 25-35 degrees C and room temperature, combined with two types of substratum, sand and vermiculite) with 5 repetitions of 20 seeds. The researcher made daily records on the number of germinated seeds, and the criteria used was protusion of the germination plug. After 35 days data become stable. The Index of Germination Speed (IVG) and germination percentage were then calculated (data were converted to sen). The averages for these two indexes were compared using the Scott-Knott method with a probability of 5%. The data show that the higher percentages of germination were obtained with a sand substratum at temperatures of 25 degrees C (86%), 25-35 degrees C (92%) and lab room temperature (93%), and with a vermiculite substratum, at temperatures of 25 degrees C (76%), 30 degrees C (83%), 20-30 degrees C (87%), 25-35 degrees C (80%) and room temperature (91%). The seeds germinated sooner in the lab environment, for both substrates. The percentage of germination at 35 degrees C was markedly lower, both on sand (21%) and vermiculite (38%). In this case, the seeds took longer to germinate and germination was not uniform.

Vermiculita como substrato para o teste de germinação de sementes de ipê-amarelo

Vermiculite is a substrate used in seedling production of forest species and can be an option for the germination test of ipe seeds. The objective of this research was to evaluate the use of vermiculite in the germination test of Tabebuia chrysotricha seeds and to stablish appropriate particle size and moisture for this substrate. Four replications of 20 seeds were sown in soil, sand, paper rolls, and vermiculite with different particle sizes: micron (0.15-0.20 mm), superthin (0.21-0.30 mm), thin (0.30-0.50 mm) and medium (0.50-1.19 mm) moistened with water equivalent to 0.5, 1.0, 1.5 and 2.0 times the weight of the dry subtrate. Germination test was carried out at 30 degrees C. The percentage of normal seedlings was obtained seven days after sowing (first count) and then weekly until 28 days, when abnormal seedlings and dead seeds were also counted. It was concluded that the germination test of ipe seeds can be carried out with thin or medium vermiculite moistened with water equivalent to 1.5 times the dry weight of the substrate. These treatments resulted in higher and faster germination (21 days).
