Undocked institutions widely dilate the scope of time-space distancing, since the separation between these elements is crucial for the extreme dynamism of modernity. This separation is the prime condition of the process of disembedding, in which the displacement of social relations of local contexts of interaction and its redesign through indefinite extensions of time and space are favored. Therefore, there are two types of dislocated mechanisms intrinsically involved in the development of social modern institutions: symbolic tokens and expert systems. These mechanisms depend on reliability. Within this context, this present paper sees the professional life cycle of the teacher in the perspective of the expert system. It also sees the work stability of public servants in the symbolic token perspective, more specifically public teachers in Brazil. This paper also attempts to propose some reflections on what a disembedding in Brazilian education would mean and on how an eventual impasse between teachercentrism and studentcentrism would affect this process if necessary or desired, from one would understand by modernity.

This was part of the post-doctorate study developed at the Faculty of Eucation in the University of Salamanca - Spain in 2010 with the Professor José Maria Hernández Díaz, who teaches the subject “History of Education” at the Pedagogy course provided by the institution. The objective of this reflection is to present some characteristics of that course, in order to highlight some of its peculiarities, and also indicate some similar issues when compared to Brazilian courses, thus producing a research useful for comparison and deepening of teacher’s training. The method was based on quali-quantitative nature (WOODS, 1996; BESSON, 1995): participant observation (EZPELETA; ROCKWELL, 1986; KETELE; ROEGIERS, 1993) and a questionnaire application (HEGENBERG, 1976; BOOTH; COLOMB; WILLIAMS, 1995) to the first and third classes in 2010, which resulted in a total of 99 students: 17 male and 82 female. This comparative information evinces the feminisation in that course, establishing direct relationship with Brazilian research. Another data, which has not yet been duly checked in Brazil, concerns the intellectual/social role of women in the classroom. Although this data is especific from that school environment, it is an important key-point for teachers’ training and teaching. The potentiality of this reflexition is exactly on this point.

As part of a round table entitled “Construction of descriptive grammars”, with authors of descriptive grammars of the Portuguese language, this text presents a personal refl ection that seeks to recover the key issues that have challenged me in this kind of work. In order to do this, I recover the historical route of the decisions I took in the construction of two manuals of Portuguese grammar and, at the same time, I gather, in other works I have written, information that can explain the guidelines adopted. Being consistent with my background and with my praxis, I offer some thoughts towards the fundamental proposition I have always considered such works to have, which is the school destination, something I can summarize in the question of what should constitute a work with the “grammar” at school.

This article, about reflections on the condition of Brazilian women from the Colony to the first decades of the twentieth century, reveals the historical position of them and the attitudes and behaviors related to gender and sexuality. Subdued, it was treated as a sexual object, arousing all sorts of misogyny by men. Rebel, veiled or ostensibly, could serve their own desires. Throughout history, the Church and medical institutions which jointly accounted for, significantly, established the meaning and place of women. In Colony period, the woman is a ward from the Catholic ideology, but from the nineteenth century, after Independence, this power control arises to Medicine. The physician submits the religious discourse, naturalizing the status of women as one that breeds, namely the insertion of the medical issues of family scientifically legitimate colonial patriarchy. This is accentuated in the early twentieth century, when medicine consolidated setting standards and rules for marriage, to motherhood and family life. We note how the feminine universe was (and it is nowadays) ambivalent, with "one foot" in virtue and another in sin, with a tendency to contain and another to trespass. On the one hand we have the home and motherhood, validated in marriage, in which the woman is cared for and dependent on her husband. Reflecting on the motherhood of Virgin Mary, comes to the sacred dimension of the idealized woman saint by the Church. At the same time, however, feels the need for freedom, identity and independence, needing to give a voice to the desire to have their sexuality and all that it is due in full. The manifestation of the desire and the call for sexual satisfaction, and put in permanent conflict personal, psychological and social split between moral entrenched across generations and cultural transformations resulting from decades of the 20th Century.

This article discusses the training of teachers to work with sexuality issues in regular school environment after the creation of the National Curriculum (PCNs) in 1997. The authors note that over a decade there have been no official regular and systematic initiatives or incentives to provide teachers with sex education disciplines at undergraduate level in Pedagogy, Teachers’ Training, Continuing Education or Initial Training courses, with rare exceptions. Generally the work with sexuality and sex education carry with it some coadjutors such as ignorance, prejudice, taboo and discrimination. In this way, if teachers are prepared to approach the field, they will experience a significant gain in performance and in the psycho-social development of their students, as well as work in a process of citizenship education.

The article is concerned with the professional development of teachers of Spanish as a foreign language (SFL). The study aimes at: (a) articulating a context for discussion on issues related to teaching SFL, and (b) identifying the main difficulties related to linguistic content and methodological aspects that students who are teachers have in regard to their professional development as SFL teachers. Participants were undergraduate student-teachers of Modern Languages who participate in the project Centro de Línguas e Desenvolvimento de Professores (CLDP). Data analysis was conducted according to the Qualitative-Interpretive Paradigm and Action Research. The results show that participation in the CLDP Project creates an academic context that facilitates the professional development of SFL teacher as the activities complement the quality of their academic education.

This paper developed a reflection about problems related to the establishment of ethical principles that guide the sexual education aiming at emancipation. Our theoretical framework is the Critical Theory of Society, in particular texts by T. W. Adorno on training, prejudice and education. It is understood that numerous difficulties are related to the achievement of an emancipatory education, and such difficulties are even greater when it comes to sex education since it is an issue that still raises irrational fears on educators, and is absent from the training they received. Following Adorno, it is understood that the current formation favors the development of subjects inclined to prejudice, and that an emancipatory sexual education involves a critique to the conditions under which such formation occurs and, at the same time, a continuous reflection about the relations between the desires and the social possibilities of their realization.

This text, homage to Ignacio Assis Silva, looks for the founding theoretical conceptions of his thoughts. When I looked at his texts, from the 70’s to the 90’s, my reading went through the path of an author who is always worried about revealing the birthplace of meaning. To catch this unique moment of semiosis, Silva proposes the concept of metamorphosis, a key-term which allows us to unite the two ends of his formation: Historical Grammar and Semiotic

The article searches to launch some analyses and investigations on the historical reach of produced participative processes in Spain and Brazil. Evidently, both the processes if had uncurled in historical, social, economic contexts and distinct politicians, but, exactly thus, keep some approaches that we intend to give prominence in the present article. How much to the dismantlement of the State of social welfare, we present, still, that in the case of Spain occurred a decentralization of its formulator power to decide arrangement of public politics that started to count on the participation of social actors in the called relational city (BECERRA, 2011). In the case of Brazil, the dictatorial period (1964-1985), the fast urban growth and the generation of precarious peripheries in the main cities, the distension and the Constituent (1986-1988) had generated the enough forces of pressure so that, gradually, if it incorporated the participative arrangement in the power to decide process.

This bibliographical article aimed to analyze the work Masculine domination of Pierre Bourdieu, considering the concepts of Analytical Psychology from C. G. Jung. Among other issues, this psychological theory is based on the analysis of the masculine and feminine principles in order to bring a different apparatus for discussion of the ideas brought by Bourdieu that involves masculine domination. The Analytical Psychology concepts understand this domination from the patriarchal view of society, according to Bourdieu in submission question that this culture imposes on women. However, there were counterpoints regarding the quality and validation of female reference that Bourdieu’s theory seems to disqualify. Among the permanencies and changes of the structures that reproduce the masculine order, both theories show agreement with updates regarding the patriarchal structure.

For a better understanding of the processing at the nucleus tractus solitarius (NTS) level of the autonomic and respiratory responses to peripheral chemoreceptor activation, herein we evaluated the role of glutamatergic neurotransmission in the intermediate (iNTS) and caudal NTS (cNTS) on baseline respiratory parameters and on chemoreflex-evoked responses using the in situ working heart-brain stem preparation (WHBP). The activities of phrenic (PND), cervical vagus (cVNA), and thoracic sympathetic (tSNA) nerves were recorded before and after bilateral microinjections of kynurenic acid (Kyn, 5 nmol/20 nl) into iNTS, cNTS, or both simultaneously. In WHBP, baseline sympathetic discharge markedly correlated with phrenic bursts (inspiration). However, most of sympathoexcitation elicited by chemoreflex activation occurred during expiration. Kyn microinjected into iNTS or into cNTS decreased the postinspiratory component of cVNA and increased the duration and frequency of PND. Kyn into iNTS produced no changes in sympathoexcitatory and tachypneic responses to peripheral chemoreflex activation, whereas into cNTS, a reduction of the sympathoexcitation, but not of the tachypnea, was observed. The pattern of phrenic and sympathetic coupling during the chemoreflex activation was an inspiratory-related rather than an expiratory-related sympathoexcitation. Kyn simultaneously into iNTS and cNTS produced a greater decrease in postinspiratory component of cVNA and increase in frequency and duration of PND and abolished the respiratory and autonomic responses to chemoreflex activation. The data show that glutamatergic neurotransmission in the iNTS and cNTS plays a tonic role on the baseline respiratory rhythm, contributes to the postinspiratory activity, and is essential to expiratory-related sympathoexcitation observed during chemoreflex activation.

In studies about the subjectivation process in contemporaneity and the social context in which one is inserted nowadays, the contemporary world is often characterized by the ascension of the narcissism – or individualism – and consumerism as a baseline to all other recent changes. The excessive valorization of aesthetics; the influence of media and marketing and the culture of image; the loss of the “inner side” and inter-human interchanges; against the exacerbation of the superficial and external, appear as essential transformations to the new configuration of the so called “post-modern” subjectivation process, privileged and reinforced by capitalist society. Next to them, exists an individual discontent – a malaise in the individual’s life – usually associated to an interior emptiness and general dissatisfaction in face of idealizations and self-esteem fluctuations. This work tries to understand how individuals establish affective bonds and social relationships in this contemporary context, connecting the contemporary context and relevant concepts to this study, including the idea of romantic love, narcissism and the “state of helplessness” in psychoanalysis, subject’s development and a parallel discussion with social-historical texts. The study, of a theoretical character, is located in the intersection between "individual" and "society" – a subjectivity, therefore, formed internally, within the individual, and submitted directly to social influence – and analyzes the determinants and influences that they exert upon one and another, based on critical-reflective readings and textual analysis of works in the fields of sociology, psychosociology and psychoanalysis.
