 Creative Education (CE) , 2019, DOI: 10.4236/ce.2019.101001 Abstract: We report on a case study of the？mathematical？content of a 10th？grade？social studies？textbook. We develop our case in three analytical steps. First, we identify, describe, and categorize the full range of mathematics in the book. Put simply, we ask: What mathematical forms (e.g., Cartesian graphs and problems) do we find and what kinds of mathematical work do they require? Second, we characterize and critically evaluate the mathematics content in the textbook, focusing in particular on the kinds of mathematics literacy and student reasoning that the book fosters. Third and finally, we operationalize a measure of the “density” of mathematics in the textbook—that is, an estimate of the presence and pervasiveness of mathematical objects and practices relative to other disciplinary contents？and track how such “density” has changed over the past three editions of the same volume. Doing so helps us further contextualize and elaborate the prior analyses, but also surfaces shifts in the patterns of mathematics presence in that textbook series, including the growing encroachment of mathematics exercising and visual/representational presence.
 Flávio Fuchs Trials , 2001, DOI: 10.1186/cvm-2-5-244 Abstract: The stepped care approach for the management of hypertension was introduced in the first United States National Guidelines issued by the National High Blood Pressure Education Program [1]. Diuretics were indicated as the first step, based on their efficacy in the first trials of prevention of cardiovascular disease and because of their better tolerability compared to the other antihypertensive drugs that were available at that time, such as the ganglion blocking agents, guanethidine, hydralazine, and reserpine. These other antihypertensive drugs were recommended as second and third steps for patients who were not controlled by diuretics alone.In the report by the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure (JNC) in 1984 (JNC-III) [2], the first recommended step was extended to include β-blockers. Four years later, in the JNC-IV report, the recommendations were extended further to include four classes of blood-pressure-lowering drugs [3]. In the subsequent guidelines, the Committee returned to diuretics or β-blockers as the first antihypertensive option, but, because of the "compelling indications", the recommendations were extended to include a wide range of the other classes of blood-pressure-lowering drugs [4].The introduction of newer classes of antihypertensive drugs was based on their presumed better tolerance and on the expectation that they would improve the prevention of coronary heart disease, which was lower than expected in the first trials, mainly attributed to adverse metabolic effects of diuretics. Physicians around the world became convinced of these advantages and the use of the newer classes of drugs surpassed diuretics and β-blockers for antihypertensive treatment.The results of recent trials and reanalysis of the previous ones show that we should return to older practices. Two recent reviews of these trials have reached opposite conclusions. Pahor et al., showed that the calcium-channel blockers are infe
 Bakhtiniana: Revista de Estudos do Discurso , 2011, DOI: 10.1590/S2176-45732011000200005 Abstract: bakhtin analyzed dostoevsky's poetics not by a partial synthesis in terms of the speech of the writer or one of his characters, but through the dialogue that would leave its contingency to assume a structural role. however, bakhtin could not demonstrate how dostoevsky's work would constitute an integral polyphonic totality. with the contribution from the critical theory, we will try to reapproach bakhtin's polyphony to the contradictory notion of totality through the dialectical method.
 Educa？？o & Sociedade , 2001, DOI: 10.1590/S0101-73302001000300011 Abstract: this paper discusses the experience of erased frontiers between public and private spaces, on the one hand, and between adults and children, on the other, which encompasses decisive, if not catastrophic consequences on the permanence of a common world and its transmissibility. the relationship between school and citizenship comes as the unifying thread in this discussion whose main argument denies the existence of the so-called "student-citizen". finally, it brings forward a brief note on a (conservative) democratic school.
 Educa？？o em Revista , 2009, DOI: 10.1590/S0102-46982009000300003 Abstract: the article focuses on the conditions in which research in higher education is carried out in brazil, at the level of post graduate studies in our universities. the main concern is the assessment process of the post graduate courses supervised by capes. after a brief presentation of the emergence and recent evolution of the country's post graduate studies in education, principles, procedures and effects of the evaluative process are related to a culture of performativity, as conceived by the british researcher stephen ball. it is argued that such category is helpful to the analysis of capes evaluation. in the final comments, the environment of post graduate courses, characterized by a culture of performativity, is compared to the way teachers have been reacting to and experiencing recent curricular reforms, according to ivor goodon's recent research. possible alternatives are then sought of.
 História, Ciências, Saúde-Manguinhos , 2012, DOI: 10.1590/S0104-59702012000500006 Abstract: the article presents serial data on african atlantic demographics in rio de janeiro in the seventeenth, eighteenth, and early decades of the nineteenth century, highlighting parish death, marriage, and baptismal registers. these represent partial, local findings from a broader demographic study underway on various urban and rural regions of slaveholding brazil, based on a variety of historical registers, which are used in an analysis of sociodemographic patterns (age, occupation, kinship, disease, gender, price) and variations in african ethnonyms from 1650 through 1870.
 Estudos Avan？ados , 2011, DOI: 10.1590/S0103-40142011000100004 Abstract: the paper starts with the idea that urban space is not a product of nature but of men′s labour. it proceeds presenting a new way of focusing and analyzing urban segregation, using the city of s？o paulo as a case study. through several social indicators, presented in 8 illustrations, it shows urban segregation in s？o paulo. it shows however that this new way also applies to any brazilian metropolitan area. important aspects shown by this new way are: on the one hand, the possibility it offers of analyzing the relationship between urban segregation of residences, working places and the overall urban spatial structure; on the other hand, the possibility of analyzing the relationship between urban segregation and the social inequality which prevails in brazilian society as well as with social domination. it finally shows the relationship between human production of urban space and human production of time and the importance of the former.
 Etnográfica , 2012, Abstract: à partir d’une enquête avec des pères homosexuels fran？ais membres de l’association des parents et futurs parents gays et lesbiens (apgl), cet article analyse les contextes sociaux d’émergence du désir d’enfant et certains enjeux liés à l’élaboration du projet parental. l’univers associatif est ici considéré non seulement comme un lieu de visibilité, mais aussi comme un espace de création de nouvelles formes familiales. ainsi, le désir d’enfant est analysé comme un fait social dont l’expression et la genèse peuvent être situées dans des contextes socioculturels particuliers.
 Arquivos de Neuro-Psiquiatria , 1994, DOI: 10.1590/S0004-282X1994000200023 Abstract: the ubiquitousness of normal yawning and the existence of abnormal yawning warrant an understanding of this reflex. its mechanisms and functional role are not entirely known. a review of the literature reveals that yawning is a brain stem arousal reflex with both peripheral and central loops subserving reversal of brain hypoxia or hypoxemia. behaviorally, yawning is a semi-involuntary act that occurs also because of loss of interest in the surroundings and it is not necessarily associated with fatigue. socio-environmental factors can influence the emergence of yawning. dopaminergic, acetylcholinergic, acthergic and oxytocinergic systems are involved in the generation and modulation of yawning in animal experimentation.
 Cadernos de Saúde Pública , 2001, DOI: 10.1590/S0102-311X2001000200014 Abstract: based on an analysis of aids cases among the xokléng indians in 1988, this article relates the illness phenomenon to socio-cultural disruptions and transformations in this indigenous group's universe, focusing on the history of their contact with brazilian national society. the analysis and interpretation of this relationship are based on anthropological theories about the centrality of the body, corporeality, and degenerative bodily processes in brazilian indigenous societies, according to which the body, society, and macro-situational elements are articulated by social praxis, and should thus be related in socio-anthropological studies of health-illness phenomena. the article briefly describes the history of epidemics emerging from contact and attempts to relate them to specific historical contexts. ethnomedical categories, cosmology, and xokléng concepts of corporeality are related to their social organization, which are thus connected to the aids cases. the latter are presented with a special focus on the relationship between their emergence and the changes occurring in the xokléng world with the construction of a dam bordering on their land.
