A propaganda de medicamentos de venda livre: um estudo do discurso e das questões éticas

A pesquisa identifica as características do discurso da propaganda de medicamentos de venda livre, analisando a relação entre o seu conteúdo, as questões éticas e as normas legais que orientam a comercialização desses medicamentos. O corpus de análise é constituído de 31 peças publicitárias de mídia impressa, de merchandising em pontos de venda PDVs, em campanhas de divulgação/comercialização de medicamentos de venda livre por um laboratório nacional EMS Sigma Pharma, e um multinacional Aventis Pharma. A metodologia de investigação é a Análise do Discurso subjacente às mensagens veiculadas nas peças de PDV, tendo como orientação os pressupostos dos teóricos de linha francesa, além dos fundamentos da propaganda e a legislação que a rege bem como os direitos do consumidor. A investigação mostra que a propaganda de medicamentos de venda livre, com seus argumentos altamente persuasivos a fim de seduzir o consumidor, não evidencia uma preocupação responsável com o consumidor e trata os medicamentos como quaisquer outros produtos, restringindo-se ao cumprimento das determinações legais em seus aspectos mínimos. Os princípios éticos e os valores sociais são ignorados, na maioria das peças, o que vale dizer que os emissores pecam por omissão na construção de seu discurso.

No gender differences in brain activation during the N-back task:An fMRI study in healthy individuals

Gender differences have been well established in verbal and spatial abilities but few studies have examined if these differences also extend into the domain of working memory in terms of behavioural differences and brain activation. The conclusions that can be drawn from these studies are not clear cut but suggest that even though gender differences might not be apparent from behavioural measures, the underlying neural substrate associated with working memory might be different in men and women. Previous research suggests activation in a network of frontal and parietal regions during working memory tasks. This study aimed to investigate gender differences in patterns of brain activation during a verbal version of the N-back working memory task, which incorporates the effects of increased demands on working memory. A total of 50 healthy subjects, aged 18 to 58 years, that were equally split by gender were recruited matched for age, levels of education and ethnicity. All subjects underwent functional magnetic resonance imaging. We found that men and women performed equally well in terms of accuracy and response times, while using similar brain regions to the same degree. Our observations indicate that verbal working memory is not affected by gender at the behavioural or neural level, and support the findings of a recent meta-analysis by Hyde ([2005]: Sex Roles 53:717-725) that gender differences are generally smaller than intra-gender differences in many cognitive domains. © 2009 Wiley-Liss, Inc.

Comparative quantitative study of ‘signature’ pathological lesions in the hippocampus and adjacent gyri of 12 neurodegenerative disorders

The hippocampus (HC) and adjacent gyri are implicated in dementia in several neurodegenerative disorders. To compare HC pathology among disorders, densities of ‘signature’ pathological lesions were measured at a standard location in eight brain regions of 12 disorders. Principal components analysis of the data suggested that the disorders could be divided into three groups: (1) Alzheimer’s disease (AD), Down’s syndrome (DS), sporadic Creutzfeldt–Jakob disease, and variant Creutzfeldt–Jakob disease in which either β-amyloid (Aβ) or prion protein deposits were distributed in all sectors of the HC and adjacent gyri, with high densities being recorded in the parahippocampal gyrus and subiculum; (2) Pick’s disease, sporadic frontotemporal lobar degeneration with TDP-43 immunoreactive inclusions, and neuronal intermediate filament inclusion disease in which relatively high densities of neuronal cytoplasmic inclusions were present in the dentate gyrus (DG) granule cells; and (3) Parkinson’s disease dementia, dementia with Lewy bodies, progressive supranuclear palsy, corticobasal degeneration, and multiple system atrophy in which densities of signature lesions were relatively low. Variation in density of signature lesions in DG granule cells and CA1 were the most important sources of neuropathological variation among disorders. Hence, HC and adjacent gyri are differentially affected in dementia reflecting either variation in vulnerability of hippocampal neurons to specific molecular pathologies or in the spread of pathological proteins to the HC. Information regarding the distribution of pathology could ultimately help to explain variations in different cognitive domains, such as memory, observed in various disorders.

Where do bright ideas occur in our brain? Meta-analytic evidence from neuroimaging studies of domain-specific creativity

Many studies have assessed the neural underpinnings of creativity, failing to find a clear anatomical localization. We aimed to provide evidence for a multi-componential neural system for creativity. We applied a general activation likelihood estimation (ALE) meta-analysis to 45 fMRI studies. Three individual ALE analyses were performed to assess creativity in different cognitive domains (Musical, Verbal, and Visuo-spatial). The general ALE revealed that creativity relies on clusters of activations in the bilateral occipital, parietal, frontal, and temporal lobes. The individual ALE revealed different maximal activation in different domains. Musical creativity yields activations in the bilateral medial frontal gyrus, in the left cingulate gyrus, middle frontal gyrus, and inferior parietal lobule and in the right postcentral and fusiform gyri. Verbal creativity yields activations mainly located in the left hemisphere, in the prefrontal cortex, middle and superior temporal gyri, inferior parietal lobule, postcentral and supramarginal gyri, middle occipital gyrus, and insula. The right inferior frontal gyrus and the lingual gyrus were also activated. Visuo-spatial creativity activates the right middle and inferior frontal gyri, the bilateral thalamus and the left precentral gyrus. This evidence suggests that creativity relies on multi-componential neural networks and that different creativity domains depend on different brain regions.

Toward an understanding of how individuals overcome challenges to development: A phenomenological study of an inner -city student's attitude toward academic orientation and life

The purpose of this qualitative case study was to gain an understanding of the phenomenon of academic orientation by seeking the insights into an inner-city Haitian-American middle school student's attitudes and world view toward education and life. A phenomenological approach was used in order to explore the way in which Cindy, a minority student, gives meaning to her lived-experiences in terms of her desire to meet academic expectations and her ability to overcome social adversity and/or other risk factors.^ The study attempted to answer the following two research questions: (1) What provides the focus for Cindy's (the subject's) approach to her school work and/or life? (2) What are the processes that give meaning and direction to academic orientation and life for Cindy? In-depth interviewing was the primary method of data collection. In addition, journal and sketchbook entries and school district records were used and classroom observations made.^ The nature of the study to understand lived-experience facilitated the use of the case study method and a phenomenological method of description. Data analysis was conducted by means of an adapted form of the constant comparative approach. Patterns in the data which emerged were coded and categorized according to underlying generative themes. Phenomenological reflection and analysis were used to grasp the experiential structures of Cindy's experience. The following textural themes were identified and confirmed to be essential themes to Cindy's experience: personal challenge to do her best, personal challenge to want to learn, having a sense of determination, being able to think for self, having a disposition to like self, achieving self-respect through performance, seeing a need to help others, being intrinsically motivated, being an independent learner, attending more to academic pressure and less to peer pressure, having motivational catalysts in her life, learning and support opportunities, and having a self-culture. Using Mahrer's humanistic theory of experiencing, Cindy's development was interpreted in terms of her progression through a sequence of developmental plateaus: externalized self, internalized self, and integrating and actualizing self.^ The findings of this study were that Cindy's desire to meet academic expectations is guided by a meaning construction internal frame of reference. High expectations of self in conjunction with other protective factors found in Cindy's home and school environments were also found to be linked to her educational resilience and success. Cindy's lived-experiences were also found to be related to Mahrer's theory of human development. In addition, it was concluded that "minority" students do not all fit into social categories and labels. ^

Reproducing Women: Female Bodily Narratives and English Patriarchies, 1600-1660

During the early Stuart period, England’s return to male monarchal rule resulted in the emergence of a political analogy that understood the authority of the monarch to be rooted in the “natural” authority of the father; consequently, the mother’s authoritative role within the family was repressed. As the literature of the period recognized, however, there would be no family unit for the father to lead without the words and bodies of women to make narratives of dynasty and legitimacy possible. Early modern discourse reveals that the reproductive roles of men and women, and the social hierarchies that grow out of them, are as much a matter of human design as of divine or natural law. Moreover, despite the attempts of James I and Charles I to strengthen royal patriarchal authority, the role of the monarch was repeatedly challenged on stage and in print even prior to the British Civil Wars and the 1649 beheading of Charles I. Texts produced at moments of political crisis reveal how women could uphold the legitimacy of familial and political hierarchies, but they also disclose patriarchy’s limits by representing “natural” male authority as depending in part on women’s discursive control over their bodies. Due to the epistemological instability of the female reproductive body, women play a privileged interpretive role in constructing patriarchal identities. The dearth of definitive knowledge about the female body during this period, and the consequent inability to fix or stabilize somatic meaning, led to the proliferation of differing, and frequently contradictory, depictions of women’s bodies. The female body became a site of contested meaning in early modern discourse, with men and women struggling for dominance, and competitors so diverse as to include kings, midwives, scholars of anatomy, and female religious sectarians. Essentially, this competition came down to a question of where to locate somatic meaning: In the opaque, uncertain bodies of women? In women’s equally uncertain and unreliable words? In the often contradictory claims of various male-authored medical treatises? In the whispered conversations that took place between women behind the closed doors of birthing rooms? My dissertation traces this representational instability through plays by William Shakespeare, John Ford, Thomas Middleton, and William Rowley, as well as in monstrous birth pamphlets, medical treatises, legal documents, histories, satires, and ballads. In these texts, the stories women tell about and through their bodies challenge and often supersede male epistemological control. These stories, which I term female bodily narratives, allow women to participate in defining patriarchal authority at the levels of both the family and the state. After laying out these controversies and instabilities surrounding early modern women’s bodies in my first chapter, my remaining chapters analyze the impact of women’s words on four distinct but overlapping reproductive issues: virginity, pregnancy, birthing room rituals, and paternity. In chapters 2 and 3, I reveal how women construct the inner, unseen “truths” of their reproductive bodies through speech and performance, and in doing so challenge the traditional forms of male authority that depend on these very constructions for coherence. Chapter 2 analyzes virginity in Thomas Middleton and William Rowley’s play The Changeling (1622) and in texts documenting the 1613 Essex divorce, during which Frances Howard, like Beatrice-Joanna in the play, was required to undergo a virginity test. These texts demonstrate that a woman’s ability to feign virginity could allow her to undermine patriarchal authority within the family and the state, even as they reveal how men relied on women to represent their reproductive bodies in socially stabilizing ways. During the British Civil Wars and Interregnum (1642-1660), Parliamentary writers used Howard as an example of how the unruly words and bodies of women could disrupt and transform state politics by influencing court faction; in doing so, they also revealed how female bodily narratives could help recast political historiography. In chapter 3, I investigate depictions of pregnancy in John Ford’s tragedy, ‘Tis Pity She’s a Whore (1633) and in early modern medical treatises from 1604 to 1651. Although medical texts claim to convey definitive knowledge about the female reproductive body, in actuality male knowledge frequently hinged on the ways women chose to interpret the unstable physical indicators of pregnancy. In Ford’s play, Annabella and Putana take advantage of male ignorance in order to conceal Annabella’s incestuous, illegitimate pregnancy from her father and husband, thus raising fears about women’s ability to misrepresent their bodies. Since medical treatises often frame the conception of healthy, legitimate offspring as a matter of national importance, women’s ability to conceal or even terminate their pregnancies could weaken both the patriarchal family and the patriarchal state that the family helped found. Chapters 4 and 5 broaden the socio-political ramifications of women’s words and bodies by demonstrating how female bodily narratives are required to establish paternity and legitimacy, and thus help shape patriarchal authority at multiple social levels. In chapter 4, I study representations of birthing room gossip in Thomas Middleton’s play, A Chaste Maid in Cheapside (1613), and in three Mistris Parliament pamphlets (1648) that satirize parliamentary power. Across these texts, women’s birthing room “gossip” comments on and critiques such issues as men’s behavior towards their wives and children, the proper use of household funds, the finer points of religious ritual, and even the limits of the authority of the monarch. The collective speech of the female-dominated birthing room thus proves central not only to attributing paternity to particular men, but also to the consequent definition and establishment of the political, socio-economic, and domestic roles of patriarchy. Chapter 5 examines anxieties about paternity in William Shakespeare’s The Winter’s Tale (1611) and in early modern monstrous birth pamphlets from 1600 to 1647, in which children born with congenital deformities are explained as God’s punishment for the sexual, religious, and/or political transgressions of their parents or communities. Both the play and the pamphlets explore the formative/deformative power of women’s words and bodies over their offspring, a power that could obscure a father’s connection to his children. However, although the pamphlets attempt to contain and discipline women’s unruly words and bodies with the force of male authority, the play reveals the dangers of male tyranny and the crucial role of maternal authority in reproducing and authenticating dynastic continuity and royal legitimacy. My emphasis on the socio-political impact of women’s self-representation distinguishes my work from that of scholars such as Mary Fissell and Julie Crawford, who claim that early modern beliefs about the female reproductive body influenced textual depictions of major religious and political events, but give little sustained attention to the role female speech plays in these representations. In contrast, my dissertation reveals that in such texts, patriarchal society relies precisely on the words women speak about their own and other women’s bodies. Ultimately, I argue that female bodily narratives were crucial in shaping early modern culture, and they are equally crucial to our critical understanding of sexual and state politics in the literature of the period.

Experiencia y construcción de significados en relación con su rol en cuidadores de personas con esquizofrenia

La perspectiva de los conocimientos situados es una postura epistemológica que surge de la corriente feminista y permite comprender las experiencias y la construcción de significados de un sujeto desde la posición que ocupa dentro de un contexto específico. Esta perspectiva no pretende generar un conocimiento generalizable, más bien busca comprender una realidad particular que viven las personas frente a problemáticas específicas. Esta perspectiva se implementó en este trabajo de grado con el objetivo de entender el significado que tiene para un cuidador informal cuidar a una persona con un diagnóstico de esquizofrenia. Este trabajo utilizó una metodología fenomenológica desde la cual se realizaron cinco entrevistas en profundidad al mismo número de cuidadores de personas con esquizofrenia donde se busca indagar acerca de la experiencia del cuidador en relación con su rol, las circunstancias por las se llega a ser cuidador, las condiciones bajo las cuales se da el cuidado, la percepción de la salud de los cuidadores y las expectativas de estas personas. La información se registró por medio de audio y de manera escrita. El análisis de la información se realizó de forma manual teniendo en cuenta a los autores Bautista (2011); Giraldo y González (2015) y Fernández (2006). Inicialmente se generaron categorías orientadoras que se fundamentaron a partir de la teoría y posteriormente se realizó la construcción de categorías emergentes. Acto seguido se contrastaron ambos tipos de categorías (teóricas y empíricas) para reflexionar acerca de la experiencia y construcción de significados de los cuidadores de personas con esquizofrenia. Se identificó que la experiencia de las cuidadoras está enmarcada en relación con el género femenino el cual ha asumido tradicionalmente esta función y también es característica que termina justificando el rol que asumen.

El rol de los actores subnacionales en la construcción de la política exterior de Japón. Estudio de caso: La disputa territorial por las islas Senkaku/Diaoyu entre Japón y China (2001-2014)

El presente estudio de caso tiene como objetivo analizar la influencia de la gobernación de Tokio en la formulación de la política exterior de Japón durante la disputa territorial por las islas Senkaku/Diaoyu. Para ello, se identifican los puntos más relevantes de la política exterior de seguridad de Japón después de la Segunda Guerra Mundial. Se hace un énfasis en la política bilateral de seguridad sino-japonesa, con el fin de ubicar el conflicto territorial por las islas Senkaku/Diaoyu como un punto importante en la agenda internacional de seguridad de ambos países. Se estudia y analiza el concepto de paradiplomacia; articulado, a su vez, por los conceptos de identidad y rol en política exterior de la perspectiva teórica del Constructivismo de las Relaciones Internacionales, para así analizar la influencia de Tokio en el manejo de la política exterior de Japón en el marco del conflicto territorial por las islas Senkaku/Diaoyu.

Orchestrating Whole Group Discourse to Mediate Mathematical Meaning

The most common pattern of classroom discourse follows a three-part exchange of teacher initiation, student response, and teacher evaluation or follow-up (IRE/IRF) (Cazden, 2001). Although sometimes described as encouraging illusory understanding (Lemke, 1990), triadic exchanges can mediate meaning (Nassaji & Wells, 2000). This paper focuses on one case from a study of discursive practices of seven middle grades teachers identified for their expertise in mathematics instruction. The central result of the study was the development of a model to explain how teachers use discourse to mediate mathematical meaning in whole group instruction. Drawing on the model for analysis, thick descriptions of one teacher’s skillful orchestration of triadic exchanges that enhance student understanding of mathematics are presented.

Metaphors in Hugo Chávez's political discourse:conceptualizing nation, revolution and opposition

This dissertation examines Hugo Chávez's choice of metaphors in his efforts to construct and legitimize his Bolivarian Revolution. It focuses on metaphors drawn from three of the most frequent target domains present in his discourse: the nation, his revolution, and the opposition. The study argues that behind an official discourse of inclusion, Chávez's choice of metaphors contributes to the construction of a polarizing discourse of exclusion in which his political opponents are represented as enemies of the nation.The study shows that Chávez constructs this polarizing discourse of exclusion by combining metaphors that conceptualize: (a) the nation as a person who has been resurrected by his government, as a person ready to fight for his revolution, or as Chávez himself; (b) the revolution as war; and (c) members of the opposition as war combatants or criminals. At the same time, the study shows that by making explicit references in his discourse about the revolution as the continuation of Bolívar's wars of independence, Chávez contributes to represent opponents as enemies of the nation, given that in the Venezuelan collective imaginary Simón Bolívar is the symbol of the nation's emancipation.This research, which covers a period of nine years (from Chávez's first year in office in 1999 through 2007), is part of the discipline of Political Discourse Analysis (PDA). It is anchored both in the theoretical framework provided by the cognitive linguistic metaphor theory developed by George Lakoff and Mark Johnson described in their book Metaphors We Live By, and in Critical Metaphor Analysis (CMA) as defined by Jonathan Charteris-Black in his book Corpus Approaches to Critical Metaphor Analysis.The study provides the first comprehensive analysis of metaphors used by Chávez in his political discourse. It builds upon the findings of previous studies on political discourse analysis in Venezuela by showing that Chávez's discourse not only polarizes the country and represents opponents as detractors of national symbols such as Bolívar or his wars of independence (which have been clearly established in previous studies), but also represents political opponents as enemies of the nation.

Optimizing the CAMCOG test in the screening for mild cognitive impairment and incipient dementia: saving time with relevant domains

Objective: To identify the CAMCOG sub-items that best contribute for the identification of patients with mild cognitive impairment (MCI) and incipient Alzheimer`s disease (AD) in clinical practice. Methods: Cross-sectional assessment of 272 older adults (98 MCI, 82 AD, and 92 controls) with a standardized neuropsychological battery and the CAMCOG schedule. Backward logistic regression analysis with diagnosis (MCI and controls) as dependent variable and the sub-items of the CAMCOG as independent variable was carried out to determine the CAMCOG sub-items that predicted the diagnosis of MCI. Results: Lower scores on Language, Memory, Praxis, and Calculation CAMCOG sub-items were significantly associated with the diagnosis of MCI. A composite score obtained by the sum of these scores significantly discriminated MCI patients from comparison groups. This reduced version of the CAMCOG showed similar diagnostic accuracy than the original schedule for the identification of patients with MCI as compared to controls (AUC = 0.80 +/- 0.03 for the reduced CAMCOG; AUC = 0.79 +/- 0.03 for the original CAMCOG). Conclusion: This reduced version of the CAMCOG had similar diagnostic properties as the original CAMCOG and was faster and easier to administer, rendering it more suitable for the screening of subtle cognitive deficits in general clinical practice.
