Although both are fundamental terms in the humanities and social sciences, discourse and knowledge have seldom been explicitly related, and even less so in critical discourse studies. After a brief summary of what we know about these relationships in linguistics, psychology, epistemology and the social sciences, with special emphasis on the role of knowledge in the formation of mental models as a basis for discourse, I examine in more detail how a critical study of discourse and knowledge may be articulated in critical discourse studies. Thus, several areas of critical epistemic discourse analysis are identified, and then applied in a study of Tony Blair’s Iraq speech on March 18, 2003, in which he sought to legitimatize his decision to go to war in Iraq with George Bush. The analysis shows the various modes of how knowledge is managed and manipulated of all levels of discourse of this speech.

Through scientific discourse and reproductive technologies, the reproductive body and the maternal body continue to be constructed as ‘natural’. At the same time,these technologies have begun to blur the boundaries between what is consideredan acceptable reproductive body, and consequently an acceptable maternal body,and an unnatural or a socially undesireable one. As science purports to offerwomen greater control over how and when they choose to procreate, through methods which range between delaying or eliminating the possibility of contraception to those which extend the possibility of conception to postmenopausal or infertile women, these same procedures raise questions about thenature and ‘naturalness’ of reproduction. Added to these concerns are thesuitablility of the reproductive body as a maternal body. Consequently, and moreand more frequently, bodies which defy ideals about maternity and motherhoodemerge, and questions about what it means to mother are raised. Bodies whichcontest the construction of motherhood as natural are frequently represented asmonstrous or freakish, and the debate between science and nature is heightened.Hiromi Goto’s short story ‘Hopeful Monsters’ resists the construction of the‘natural’ maternal body by highlighting the way in which women’s bodies areshaped by scientific discourse. In turn, images of ‘monstrous’ mothers emerge andare challenged, suggesting the need to reimagine what it means to mother and whatit means to be a mother. Through reading a selection of the stories this paper willinterrogate possible alternatives to constructions of the ‘natural’ maternal body and motherhood, suggesting that the Goto’s ‘monsters’ are perhaps only monstrous as a result of scientific discourse which constructs them as such.

Understanding how blogs can support collaborative learning is a vital concern for researchers and teachers. This paper explores how blogs may be used to support Secondary Education students’ collaborative interaction and how such an interaction process can promote the creation of a Community of Inquiry to enhance critical thinking and meaningful learning. We designed, implemented and evaluated a science case-based project in which fifteen secondary students participated. Students worked in the science blogging project during 4 months. We asked students to be collaboratively engaged in purposeful critical discourse and reflection in their blogs in order to solve collectively science challenges and construct meaning about topics related to Astronomy and Space Sciences. Through student comments posted in the blog, our findings showed that the blog environment afforded the construction of a Community of Inquiry and therefore the creation of an effective online collaborative learning community. In student blog comments, the three presences for collaborative learning took place: cognitive, social, and teaching presence. Moreover, our research found a positive correlation among the three presences –cognitive, social and teaching– of the Community of Inquiry model with the level of learning obtained by the students. We discuss a series of issues that instructors should consider when blogs are incorporated into teaching and learning. We claim that embedded scaffolds to help students to argue and reason their comments in the blog are required to foster blog-supported collaborative learning.

Peering into the field of Alzheimer's disease (AD), the outsider realizes that many of the therapeutic strategies tested (in animal models) have been successful. One also may notice that there is a deficit in translational research, i.e., to take a successful drug in mice and translate it to the patient. Efforts are still focused on novel projects to expand the therapeutic arsenal to 'cure mice.' Scientific reasons behind so many successful strategies are not obvious. This article aims to review the current approaches to combat AD and to open a debate on common mechanisms of cognitive enhancement and neuroprotection. In short, either the rodent models are not good and should be discontinued, or we should extract the most useful information from those models. An example of a question that may be debated for the advancement in AD therapy is: In addition to reducing amyloid and tau pathologies, would it be necessary to boost synaptic strength and cognition? The debate could provide clues to turn around the current negative output in generating effective drugs for patients. Furthermore, discovery of biomarkers in human body fluids, and a clear distinction between cognitive enhancers and disease modifying strategies, should be instrumental for advancing in anti-AD drug discovery.

Hacia fines del siglo XX, en Latinoamérica se publica una gran producción de novelas calificadas como históricas, notable cuantitativa y cualitativamente. Sus novedosas propuestas y las diferencias que guarda respecto a las características tradicionales del género, provocan un cuestionamiento crítico respecto a la categoría de novela histórica. En general, las producciones recientes problematizan las posibilidades del conocimiento histórico, como también las posibilidades del lenguaje para expresar ese conocimiento. Además, contienen una fuerte crítica hacia el discurso historiográfico oficial y recurren a la historia, no como producto acabado o dato, sino como procedimiento narrativo y cognoscitivo. Esto les permite trascender la referencia histórica local –sin excluirla – para remitir de manera más amplia a la historiografía y a la historia como portadores de la verdad sobre el pasado. La investigación analiza un corpus de novelas argentinas de finales del siglo pasado indagando los conceptos de historia y ficción propuestos por los textos.

This Working Paper aims to offer an up-to-date list of cultural relativist players and arguments with respect to human rights, constituted by China, Viet Nam, Myanmar, Iran, Pakistan, Yemen, Syria, Malaysia and Cuba. This working paper argues that Indonesia, Iraq, Colombia and Mexico are not in the same cultural relativist group of states maintained by renowned scholars, notably Cristina Cerna and Dianne Otto. As such, apart from this form of cultural relativism based on the respect for the self-determination of indigenous peoples and communities, this working paper exposes two different categories of radical cultural relativism based on revolutionary discourse and/or radical Islamism, as well as targets the credibility on the latter two based on the information facilitated by the United Nations (UN) Human Rights Council (HRC) Universal Periodic Review (UPR).

En esta comunicación vamos a examinar los patrones que sigue la codificación sintáctica en los conectores causales resultantes de procesos de gramaticalización. Tal como observó Givón (1979:107), la dirección de los procesos de codificación puede producirse desde el discurso a la sintaxis. Esta idea se ha retomado en teorías más recientes como, por ejemplo, la Teoría de la Relevancia, desarrollada en distintos trabajos de Sperber y Wilson, entre otros. La aplicación de esta teoría en el ámbito de los conectores discursivos ha sido llevada a cabo por distintos autores, entre los cuales destaca Blakemore. El propósito de nuestro trabajo residirá en integrar las ventajas de un análisis pragmático discursivo como la citada Teoría de la Relevancia con una teoría sintáctica formal de la gramaticalización, concretamente la que proponen dentro del marco de la gramática generativa Roberts y Roussou (2003). Esto permitirá profundizar, por un lado, en el tipo de codificación de las instruccions lingüísticas que aportan los conectores (información procedimental) y, por otro, en la relación lógico-discursiva entre las proposiciones y en la propia estructura del nexo

En el context de la crisi econòmica i social que vivien els Estats Units a començament dels anys trenta, diversos actors polítics i socials van elaborar missatges que provaven d’acarar els ciutadans amb la realitat, però sobretot de restituir-los la confiança en ells mateixos i en el país. Aquest article analitza els discursos i les aportacions ideològiques de dues de les personalitats més destacades que participaren en aquest procés de reconstrucció emocional: el president Franklin D. Roosevelt i el cineasta Frank Capra. El text cerca d’establir les connexions entre aquests dos discursos, descobrir-ne les coincidències i, també, les diferències, i plantejar una aproximació al cinema com un mitjà de comunicació que va més enllà del simple entreteniment, per a convertir-se, en diverses ocasions, en un eficaç document amb el qual apropar-se a una època, desxifrar-ne els aspectes més significatius

The aim of this working paper is to analyze the inclusion of political humor into the set of actions used by opponents to the Syrian regime during the first year of a state-wide uprising in 2011. The research argues that although political humor has traditionally been seen mainly as a concealed voice against dominant elites, it can nevertheless take a confrontational stance and challenge a regime. In this paper we assess the role of political humor in challenging the legitimacy of the Syrian State through the battle for the signification of events. We will work with a theoretical framework that draws its assumptions from social movements’ studies and cultural studies. Through the assessment of the importance of discourse and the role of ideological domination to a regime we will see how the first year of the Syrian uprising included widespread acts of political humor as part of the strategy against the regime.

En el marc de la recerca sobre identitats i nova ciutadania, l’objecte d’aquest treball és reconèixer elements clau dels processos d’identificació nacional a Catalunya en la població nouvinguda, i identificar els factors que n'afavoreixen la seva vinculació comunitària. La recerca s'ha desenvolupat en un primer bloc analitzant la perspectiva sociològica entorn a la idea d’identitat, així com l’evolució del discurs identitari a Catalunya, a fi de continuar desenvolupant amb profunditat el debat sobre identitat i nació en relació al fet migratori i la diversitat social existent. En un segon bloc d’anàlisi, la recerca fixa la mirada a una dotzena de casos treballats a través d’històries de vida de diverses realitats migratòries del nostre país corresponents a les diverses onades del segle XX, tant d’immigració espanyola com d'immigració de fora de l'Estat espanyol. La voluntat d’aquest segon bloc és extreure experiències socials d’interpretacions individuals que assenyalin quins elements permeten o dificulten la mobilitat social, quines experiències tenen valor identitari i de quin tipus, i quins fenòmens esdevenen rellevants en la configuració d’espais de referència i identificació nacional a nivell individual. Finalment s’incorpora un apartat d’entrevistes en profunditat a diversos actors socials i polítics rellevants a fi de reconèixer aquells elements que centren el discurs de la “nova cultura pública comuna”. L’objectiu és interrelacionar el discurs polític i filosòfic actual amb l’experiència biogràfica de les persones, assenyalant aquells elements que han estat significatius per a la seva identitat com a catalans i catalanes o, ans al contrari, que no han afavorit una situació en aquests termes. En aquest sentit la pregunta que vincula aquest espai de reflexió és: Quins elements afavoreixen la identificació nacional englobant la diversitat social existent i quins mecanismes d'adhesió hi podrien funcionar?

In recent grammars and dictionaries also (`therefore, so, well¿) continues to be preferably presented as an adverb with a conclusive-consecutive connective function that essentially corresponds to its use in formal written German. Its function as a modal particle is documented, however, since the beginnings of what is known as Partikelforschung, though not all its uses have been systematically investigated contrasting oral and written German, either in mode or concept. In this article we analyse the uses of also in semi-informal oral interactions on the basis of empirical data (from a subsample of the VARCOM corpus). Specifically, we will analyse the presence and frequency of also at the beginning of a sentence or sequence, the functions it serves as a logical-semantic connector or discourse and interaction marker and the interrelations between these functions, in order to contrast these results with the description of also provided by current reference works.

Intervenir eficaçment en les dificultats d'aprenentatge que presenten els nostres alumnes es converteix sovint en un repte per als educadors. En el decurs del segle passat hi havia un predomini clar de l'estudi de les dificultats de la lectoescriptura basat en el 'resultat o producte escrit', és a dir, s'observaven les errades comeses a l'hora de llegir i/o d'escriure i es procurava incidir en el canvi bo i focalitzant la majoria dels esforços en la millora d'aquest resultat o producte. Amb l'apropament de les investigacions provinents de la neurociència en el camp educatiu, se'ns mostra la possibilitat d'apropar-nos a l'origen, a l'engranatge gràcies al qual els humans podem escriure, llegir i aprendre. Estem parlant d'apropar-nos a l'explicació de com funciona el nostre cervell tant en l'àmbit dels processos cognitius com dels processos emocionals

Els autors s’endinsen en aquest article en l’estudi de les relacions entre geografia, orientalisme i colonialisme a Europa al tombant del segle passat, tot introduint la perspectiva de gènere i en el marc d'un interès més general per la història del pensament geogràfic contemporani. Ho fan a partir de l’anàlisi contextualitzada d'un text de l’època que fa referència al cas espanyol i a la seva aventura colonial africana. Es tracta del llibre El Marroc sensual i fanàtic (1936) d’Aurora Bertrana, una versió molt elaborada del discurs de la diferència i una bona il•lustració de la literatura de viatges de dones europees, força excepcional i atípica -això sí- en el context literari català i espanyol de l’època

It has been suggested that decisionmaking depends on sensitive feelings associatedwith cognitive processing rather than cognitiveprocessing alone. From human lesions, we knowthe medial anterior inferior-ventral prefrontalcortex processes the sensitivity associated withcognitive processing, it being essentiallyresponsible for decision making.In this fMRI (functional Magnetic ResonanceImage) study 15 subjects were analyzed usingmoral dilemmas as probes to investigate the neuralbasis for painful-emotional sensitivity associatedwith decision making. We found that a networkcomprising the posterior and anterior cingulateand the medial anterior prefrontal cortex wassignificantly and specifically activated by painfulmoral dilemmas, but not by non-painful dilemmas.These findings provide new evidence that thecingulate and medial anterior prefrontal areinvolved in processing painful emotionalsensibility, in particular, when decision makingtakes place. We speculate that decision makinghas a cognitive component processed by cognitivebrain areas and a sensitivity component processedby emotional brain areas. The structures activatedsuggest that decision making depends on painfulemotional feeling processing rather than cognitiveprocessing when painful feeling processinghappens
