Teaching with an Attitude: Finding Ways to the Conundrum of a Postmodern Curriculum  [PDF]
Ana Paula Martinez Duboc
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.412A2009
Abstract: Several scholars in the field of education have questioned the constituent aspects of a curriculum that would better respond to the rising demands in contemporary societies. The relevance of such enquiry finds its place in the very transformations in today’s societies marked by significant changes in the ways of knowing, being, and acting primarily due to the advent of new digital media in more recent globalizing processes. As Burke (2009) has stated, if schools wish to maintain their relevance in society, they must take into account such changes by first and foremost acknowledging the new and complex ways of making meanings in out-of-school literacy practices as equally legitimating those happening within school contexts. Along with Burke (ibid.), this paper advocates the need of rethinking the notion of curriculum in the light of the new ontologies and epistemologies of postmodernity. Such task proves itself to be a conundrum inasmuch as the very notion of curriculum has been traditionally founded on modern principles such as linearity, stability, and universality (Silva, 2009). In view of this, how can educators respond to the challenge of redefining what should be taught in schools in postmodern times so that students would better perform in relation to the self and the other within their social practices? This paper aims to analyse the relationship between postmodern philosophical concepts, curriculum theory and educational practice by presenting the notion of curricular attitude (Duboc, 2012) as a local redesign of teaching practices within a Brazilian educational context. Despite being situated in the field of foreign language teaching, the notion of a curricular attitude might be of interest of other areas of knowledge since it seeks to revisit teaching practices in the light of wider philosophical concerns.

Abstract: this paper aims at discussing english curricular guidelines for brazilian elementary and secondary schools towards recent transformations in contemporary societies. in doing so, we assume the new literacy studies as our theoretical framework for its insightful re-conceptualizations of knowledge, language and pedagogy. the paper will present a brief reflection on two curricular guidelines recently launched in brazil in different scales. firstly, the study will investigate the epistemological bases that underlie both guidelines. secondly, we intend to expand such reflection by interpreting both proposals in the light of the new global demands, with emphasis on the local-global dilemma.
O momento da saída do abrigo por causa da maioridade: a voz dos adolescentes
Ana Laura Moraes Martinez,Ana Paula Soares-Silva
Psicologia em Revista , 2008,
Abstract: O que significa para um adolescente crescer num abrigo? E o que significa para ele ter que deixá-lo por causa da maioridade legal? Na tentativa de compreender essas quest es, a presente pesquisa foi construída junto com dois adolescentes que vivenciavam a saída do abrigo, após terem permanecido na institui o por 12 anos. Partindo de uma perspectiva histórico-cultural, utilizou-se para a constru o do corpus, observa es participantes, entrevistas com os adolescentes e equipe técnica, além de produ es narrativas de um dos adolescentes. O eixo norteador da análise foram os sentidos produzidos sobre a saída do abrigo. Entre os apontamentos finais, verificou-se a ausência de práticas sistemáticas de auxílio aos adolescentes no enfrentamento da saída e a existência de atua es individualizadas, permeadas pelos estereótipos construídos pela institui o. Enquanto um dos adolescentes (o adolescente ativo) construiu arranjos próprios para sua saída, o outro (o adolescente problema) foi intensamente tutelado pela institui o nesse processo de desligamento.

Abstract: soybeans present commercial and nutritional importance, but they contain some components that decrease the availability of some nutrients. germination has a positive effect on the increase of the nutritional quality of the grain due to the changes that occur in the process because of the difference in vegetable kind, variety of seed, and the germination conditions. the objective of this research was to analyze soybean grains before and after 48 hours germination. centesimal composition, tripsin inhibitor, phytic acid, tannins, total phenolics, availability and amount of in vitro iron, in vitro protein digestibility and antioxidant activity analysis by dpph and abts were performed. the germination process altered the chemical composition of the grain and the iron and protein availability. the results showed that germination reduced tannins, available carbohydrates, and the antioxidant activities by dpph and abts methods. the germination process increased the moisture, lipid, protein, soluble fiber, in vitro protein digestibility, and total phenolics of the grain. germination did not alter significantly the content of ash, insoluble fiber, amount of iron and its availability, phytic acid, and tripsin inhibitor. although germination time was low, changes occurred in the grain composition promoting increase in the nutritional quality.

Carlotti, Ana Paula de Carvalho Panzeri;Ferlin, Maria Lúcia Silveira;Martinez, Francisco Eulógio;
Sao Paulo Medical Journal , 2007, DOI: 10.1590/S1516-31802007000300010
Abstract: context and objective: neonatal resuscitation should be part of medical school curriculums. we aimed to evaluate medical school graduates' knowledge of neonatal resuscitation. design and setting: cross-sectional study on the performance of candidates sitting a medical residency exam at hospital das clínicas, faculdade de medicina de ribeir?o preto, universidade de s?o paulo, in 2004. methods: there were two questions on neonatal resuscitation. one question in the theory test aimed at evaluating basic knowledge on the initial approach towards newly born infants. the question in the practical exam was designed to evaluate the candidate's ability to perform the initial steps of resuscitation and to establish bag-mask ventilation. results: out of 642 candidates from 74 medical schools, 151 (23.5%) answered the theory question correctly. significantly more physicians from public medical schools in the state of s?o paulo answered correctly than did those from other schools in brazil (52.5% versus 9.2%; p < 0.05). a total of 436 candidates did the practical exam. the grades among graduates from medical schools belonging to the state of s?o paulo were significantly higher than among those from other schools (5.9 ± 2.6 versus 4.1 ± 2.1; p < 0.001). the grades for the practical question among candidates who had answered the theory question correctly were significantly higher than those obtained by candidates who had given wrong answers (p < 0.05). conclusion: medical school graduates' knowledge of neonate resuscitation in the delivery room is quite precarious. emphasis on neonatal resuscitation training is urgently needed in medical schools.

Abstract: We have obtained optical multicolour (UBVRI) linear polarimetric data for 46 of the brightest stars in the area of the open cluster NGC 6124 in order to investigate the properties of the interstellar medium (ISM) that lies along the line of sight toward the cluster. Our data yield a mean polarization efficiency of $P_V/E_{B-V}=3.1\pm$0.62, i.e., a value lower than the polarization produced by the ISM with normal efficiency for an average color excess of $E_{B-V}=0.80$ as that found for NGC 6124. Besides, the polarization shows an orientation of $\theta \sim 8^\circ$.1 which is not parallel to the Galactic Disk,an effect that we think may be caused by the Lupus Cloud. Our analysis also indicates that the observed visual extinction in NGC 6124 is caused by the presence of three different absorption sheets located between the Sun and NGC 6124. The values of the internal dispersion of the polarization ($\Delta P_V\sim 1.3% $) and of the colour excess ($\Delta E_{B-V}\sim 0.29$ mag) for the members of NGC 6124 seem to be compatible with the presence of an intra-cluster dust component. Only six stars exhibit some evidence of intrinsic polarization.Our work also shows that polarimetry provides an excellent tool to distinguish between member and non-member stars of a cluster.

Abstract: objective: to compare the metabolic effects of diets based on palm oil and hydrogenated fat on young rats. methods: wistar female rats, during lactation, were fed diets with different lipid sources, which were also adjusted to the recommendations (american institute of nutrition-93) and given to the male pups from the 21rst day to the 45th day of life, when they were killed. the epididimal and perirenal adipose tissues were extracted and had their lipogenesis rates measured in vivo with 3h2o. we also measured, in the plasma, the fatty acids profile, using gas cromatography, and the triglyceride and total cholesterol levels, using enzymatic kits. results: the replacement of dietary hydrogenated fat by palma oil, increased in the plasma the proportion of araquidonic fatty acid, and decreased the proportion of linolenic essential fatty acid, as well as the levels of triglyceride and total cholesterol. the lipid contents and the epidimal and perirenal lipogenic rates increased, resulting in higher body weight and adiposity. conclusion: the type of dietary fatty acid offered since the lactation period, can affect the lipid metabolism of the adipose tissue in early age, as well as the alimentary behavior and the gain of body weight, with possible repercussions on the development of non-transmissible chronic disease.

Abstract: We evaluated 345 HIV-infected patients on cART using two different MS definitions (NCEP-ATPIII-2005 and IDF-2005) and the Framingham risk score.CL was present in 58.7% of the patients. The prevalence of the MS was 52.2% (ATPIII) and 43.2% (IDF), and it was not significantly different between patients with (W) or without (WT) CL, regardless of the definition used (ATPIII WCL 52.9% vs WT CL 51.1%; p = 0.738; IDF WCL 41.3% vs WTCL 46.0%; p = 0.379). Moderate concordance was observed between the 2 definitions (kappa = 0.484; p < 0.001) and after gender stratification there was good concordance in women (kappa = 0.759; p < 0.001). Patients with CL had lower waist circumference and HDL-C and higher triglycerides levels. In women, CL was significantly associated with MS, hypertriglyceridemia and low HDL cholesterol independently of age, cART and BMI. Patients with CL had a significantly higher risk of coronary heart disease at 10 years, measured by the Framingham risk score, than patients without CL. Those with CL and with MS had higher frequencies of moderate and high risk categories than those without MS.The prevalence of the MS was high in these HIV-infected patients with an age average of 40 years and this finding could explain why HIV patients have an increased risk for cardiovascular disease (CVD).Combination antiretroviral therapy (cART) has changed the course of HIV infection, leading to a significant reduction in AIDS related morbidity and mortality [1]. However, cART is known to be associated with changes in fat distribution (lipodystrophy) and metabolic abnormalities, including insulin resistance, dyslipidemia, and increased blood pressure (BP) [2,3].The Metabolic syndrome (MS), a common condition in the general population, refers to a constellation of cardiovascular disease (CVD) risk factors, including increased waist circumference (WC), glucose and lipid metabolism disorders, and hypertension [4,5]. Each of these risk factors individually increases cardiovasc

Abstract: chromosomal translocations are characteristic of hematopoietic neoplasias and can lead to unregulated oncogene expression or the fusion of genes to yield novel functions. in recent years, different lymphoma/leukemia-associated rearrangements have been detected in healthy individuals. in this study, we used inverse pcr to screen peripheral lymphocytes from 100 healthy individuals for the presence of mll (mixed lineage leukemia) translocations. forty-nine percent of the probands showed mll rearrangements. sequence analysis showed that these rearrangements were specific for mll translocations that corresponded to t(4;11)(q21;q23) (66%) and t(9;11) (20%). however, rt-pcr failed to detect any expression of t(4;11)(q21;q23) in our population. we suggest that 11q23 rearrangements in peripheral lymphocytes from normal individuals may result from exposure to endogenous or exogenous dna-damaging agents. in practical terms, the high susceptibility of the mll gene to chemically-induced damage suggests that monitoring the aberrations associated with this gene in peripheral lymphocytes may be a sensitive assay for assessing genomic instability in individuals exposed to genotoxic stress.

Infectious Diseases in Obstetrics and Gynecology , 2012, DOI: 10.1155/2012/727248
Abstract: The aim of this work was to study the anti-Candida activity of lidocaine and nitroglycerin alone and in combination. Ten Candida strains were included, corresponding to 1 collection type strain (ATCC 10231) and 9 clinical isolates: 4 C. albicans, 2 C. glabrata, 1 C. tropicalis, 1 C. krusei, and 1 C. parapsilosis. The CLSI reference M27-A3 micromethod was used to determine the anti-Candida activity of the drugs alone; minimal inhibitory and lethal concentrations were determined. The classic checkboard technique was used to determine the activity of combined drugs. Lidocaine fungicidal effect was dosedependent. Nitroglycerin exhibited a higher effect. The drugs combination resulted in a reduction of the inhibitory concentration, corresponding to an additive effect. In conclusion, both drugs exhibited an interesting anti-Candida activity. The combination of lidocaine with nitroglycerin was shown to have an additive effect against Candida spp., predicting the interest to include, in the future, these drugs in a new delivery system for the treatment of mucocutaneous candidosis. 1. Introduction Candida spp. are microorganisms frequently found in the human oral cavity, gastrointestinal tract, and vagina [1–4]. Among mucocutaneous infections, vulvovaginal candidosis (VVC) is the second most frequent vaginal infection, after vaginal bacteriosis and is one of the most common clinical diseases caused by Candida spp. It affects 70–75% of women at least once in their lifetime while 40–50% of them will experience a recurrence; 5–8% of adult women develop recurrent vulvovaginal candidosis (RVVC), defined as four or more episodes within a year [3–7]. The main goal of VVC treatment is the control and immediate relief of its signs and symptoms, related to vulvovaginal inflammation, as quickly as possible and the mycological cure to be confirmed some days later; recurrence prevention is also pursued [8]. VVC is usually treated very effectively with azoles, which are present in the most prescribed therapeutic regimens, unless a suspected or confirmed azole-resistant Candida strain is involved. On the other hand, most gynecologists believe that the control of RVVC requires both systemic and local therapy, also involving new antifungal drugs and strategies [3, 9, 10]. Despite RVVC being considered a Candida infection that is more dependent on the host characteristics, therapeutics approaches available and able to allow a remission of the symptoms between episodes are antifungal drugs used for a long period of time [8, 9, 11]. Some authors consider that new therapeutic
