The Freudian unconscious in the context of the cognitive orientation

For decades psychoanalysis was the discipline studying the unconscious, and other branches of study lacked competence to take a stand on the issues concerning the unconscious. From 1980s onwards intense study of the unconscious has been taken place in the scope of cognitive orientation. Thus, nowadays it is talked about both pyschoanalytic and cognitive unconscious. The aim of this thesis is to integrate psychoanalytic and cognitive views. When the "Freudian" conception of the unconscious is considered, there are four entangled issues: 1) what is the unconscious like, 2) how does the unconsciuos give rise to psychic disorders 3) why and how certain contents are missing from consciousness (repression of contents), 4) the emergence of those contents (becoming conscious of the repressed). The conventional psychoanalytic answer to the first question - and "the cornerstone of psychoanalysis" - is "the unconscious is mental". The issues 2)-4) depend radically on the answer given to the 1): "psychoanalytic" conceptualizations on them rest on the "cornerstone". That ground was challended in study I: it was argued that it has never been clear what does it mean that the unconscious is mental. Thus, it was stated that in the current state of art psychoanalysis should drop out the ephitet "mental" before the term unconscious. That claim creates a pressure to reappraise the convential "psychoanalytic" answers to the other questions, and that reappraisal was the aim of studies II and III. In study II the question 2) is approached in terms of implicit knowledge. Study III focuses on mechanisms, which determine which contents appear in the scope of consciousness, and also cause missing of contents from there (the questions 3) and 4)). In the core of study III there are distinctions concerning the processess occuring in the levels of the brain, consciousness, self-consciousness, and narrative self-consciousness. Studies I-III set "psychoanalytic" topics in the frames of cognitive view. The picture emerging from those studies is not especially useful for a clinican (psychotherapist). Studies IV and V focused that issue. Study IV is a rather serious critique toward neuropsychoanalysis. In it it was claimed that repressive functions of conscious states are in the core of clinical psychoanalysis, and functions in general cannot be reduced to neurophysiological terminology. Thus, the limits of neuropsychoanalysis are more strict than it has been realized: crucial clinical issues remain outside its scope. In study V it was focused on the confusing state of things that although unconscious fantasies do not exist, the idea on them has been an important conceptual tool for clinicans. When put in a larger context, the aim of study V is similar to that of study IV: to determine the relation between psychotherapists' and neuroscientists' terminologies. Studies III, IV and V apply the philosopher Daniel Dennett's model on different levels of explanation.

Personality in sport and exercise psychology: Integrating a whole person perspective

This paper draws on contemporary views in personality psychology as a means for understanding people participating in sport and physical activity. Specifically, we focus on McAdams’ integrative framework [McAdams (2013). The psychological self as actor, agent, and author. Perspectives on Psychological Science, 8, 272–295; McAdams & Pals (2006). A new big five: Fundamental principles for an integrative science of personality. American Psychologist, 61, 204–217] and suggest this framework as potentially generative in the field of sport and exercise psychology. McAdams indicates that people can be defined through three layers of understanding, incorporating (a) dispositional traits, (b) characteristic adaptations, and (c) narrative identities. Together these layers provide a vision of the whole person – a perspective of personality rarely adopted by the sport and exercise community. The aim of this paper is to introduce scholars and practitioners to the potential benefits of embracing this whole person outlook, and to discuss the opportunities and challenges McAdams’ framework may have for advancing scholarship in sport and exercise psychology.

Is stereotype threat a useful construct for organizational psychology research and practice?

Stereotypes about different groups persist in organizations. Employees from such groups may experience stereotype threat, or the concern that they are being judged on the basis of demeaning stereotypes about groups to which they belong. The goal of this focal article is to discuss whether stereotype threat is a useful construct for organizational psychology research and practice. To this end, we focus on consequences other than acute performance deficits in laboratory settings. In particular, we examine studies that highlight the effects of stereotype threat on intrapersonal outcomes (e.g., job attitudes), interpersonal outcomes (e.g., negotiation), and on the relationship between employees and their organization. The research reviewed suggests that stereotype threat is a potentially important phenomenon in organizations, but it also highlights the paucity of research in an organizational context. We provide suggestions for future research directions as well as for the prevention and amelioration of stereotype threat in the workplace.

Essays in Philosophical Moral Psychology

The dissertation consists of four essays and a comprehensive introduction that discusses the topics, methods, and most prominent theories of philosophical moral psychology. I distinguish three main questions: What are the essential features of moral thinking? What are the psychological conditions of moral responsibility? And finally, what are the consequences of empirical facts about human nature to normative ethics? Each of the three last articles focuses on one of these issues. The first essay and part of the introduction are dedicated to methodological questions, in particular the relationship between empirical (social) psychology and philosophy. I reject recent attempts to understand the nature of morality on the basis of empirical research. One characteristic feature of moral thinking is its practical clout: if we regard an action as morally wrong, we either refrain from doing it even against our desires and interests, or else feel shame or guilt. Moral views seem to have a conceptual connection to motivation and emotions – roughly speaking, we can’t conceive of someone genuinely disapproving an action, but nonetheless doing it without any inner motivational conflict or regret. This conceptual thesis in moral psychology is called (judgment) internalism. It implies, among other things, that psychopaths cannot make moral judgments to the extent that they are incapable of corresponding motivation and emotion, even if they might say largely the words we would expect. Is internalism true? Recently, there has been an explosion of interest in so-called experimental philosophy, which is a methodological view according to which claims about conceptual truths that appeal to our intuitions should be tested by way of surveys presented to ordinary language users. One experimental result is that the majority of people are willing to grant that psychopaths make moral judgments, which challenges internalism. In the first article, ‘The Rise and Fall of Experimental Philosophy’, I argue that these results pose no real threat to internalism, since experimental philosophy is based on a too simple conception of the relationship between language use and concepts. Only the reactions of competent users in pragmatically neutral and otherwise conducive circumstances yield evidence about conceptual truths, and such robust intuitions remain inaccessible to surveys for reasons of principle. The epistemology of folk concepts must still be based on Socratic dialogue and critical reflection, whose character and authority I discuss at the end of the paper. The internal connection between moral judgment and motivation led many metaethicists in the past century to believe along Humean lines that judgment itself consists in a pro-attitude rather than a belief. This expressivist view, as it is called these days, has far-reaching consequences in metaethics. In the second essay I argue that perhaps the most sophisticated form of contemporary expressivism, Allan Gibbard’s norm-expressivism, according to which moral judgments are decisions or contingency plans, is implausible from the perspective of the theory of action. In certain circumstances it is possible to think that something is morally required of one without deciding to do so. Morality is not a matter of the will. Instead, I sketch on the basis of Robert Brandom’s inferentialist semantics a weak form of judgment internalism, according to which the content of moral judgment is determined by a commitment to a particular kind of practical reasoning. The last two essays in the dissertation emphasize the role of mutual recognition in the development and maintenance of responsible and autonomous moral agency. I defend a compatibilist view of autonomy, according to which agents who are unable to recognize right and wrong or act accordingly are not responsible for their actions – it is not fair to praise or blame them, since they lacked the relevant capacity to do otherwise. Conversely, autonomy demands an ability to recognize reasons and act on them. But as a long tradition in German moral philosophy whose best-known contemporary representative is Axel Honneth has it, both being aware of reasons and acting on them requires also the right sort of higher-order attitudes toward the self. Without self-respect and self-confidence we remain at the mercy of external pressures, even if we have the necessary normative competence. These attitudes toward the self, in turn, are formed through mutual recognition – we value ourselves when those who we value value us. Thus, standing in the right sort of relations of recognition is indirectly necessary for autonomy and moral responsibility. Recognition and valuing are concretely manifest in actions and institutions, whose practices make possible participation on an equal footing. Seeing this opens the way for a kind of normative social criticism that is grounded in the value of freedom and automomy, but is not limited to defending negative rights. It thus offers a new way to bridge the gap between liberalism and communitarianism.

A “business researcher” view on opportunities for psychology in entrepreneurship research

In this short essay I offer some “business researcher” advice on how to leverage a strong background in psychology when attempting to contribute to the maturing field of “entrepreneurship research”. Psychologists can benefit from within-discipline research, e.g. on emergence, small groups, fit, and expertise as well as method strengths in, e.g. experimentation, operationalisation of constructs, and multi-level modelling. However, achieving full leverage of these strengths requires a clear conceptualisation of “entrepreneurship” as well as insights into the challenges posed by the nature of this class of phenomena.

Notions of Nation : A Critical Discursive Psychology perspective on the Isle of Man

At the the heart of this study can be seen the dual concern of how the nation is represented as a categorical entity and how this is put to use in everyday social interactions.This can be seen as a reaction to the general approach to categorisation and identity functions that tend to be reified and essentialized within the social sciences. The empirical focus of this study is the Isle of Man, a crown dependency situated geographically central within the British Isles while remaining political outside the United Kingdom. The choice of this site was chosen explicitly as ‘notions of nation’ expressed on the island can be seen as being contested and ephemerally unstable. To get at these ‘notions of nation’ is was necessary to choose specific theoretical tools that were able to capture the wider cultural and representational domain while being capable of addressing the nuanced and functional aspects of interaction. As such, the main theoretical perspective used within this study was that of critical discursive psychology which incorporates the specific theoretical tools interpretative repertoires, ideological dilemmas and subject positions. To supplement these tools, a discursive approach to place was taken in tandem to address the form and function of place attached to nationhood. Two methods of data collection were utilized, that of computer mediated communication and acquaintance interviews. From the data a number of interpretative repertoires were proposed, namely being, essential rights, economic worth, heritage claims, conflict orientation, people-as-nation and place-as-nation. Attached to such interpretative repertoires were the ideological dilemmas region vs. country, people vs. place and individualism vs. collectivism. The subject positions found are much more difficult to condense, but the most significant ones were gender, age and parentage. The final focus of the study, that of place, was shown to be more than just an unreflected on ‘container’ of people but was significant in terms of the rhetorical construction of such places for how people saw themselves and the discursive function of the particular interaction. As such, certain forms of place construction included size, community, temporal, economic, safety, political and recognition. A number of conclusions were drawn from the above which included, that when looking at nation categories we should take into account the specific meanings that people attach to such concepts and to be aware of the particular uses they are put to in interaction. Also, that it is impossible to separate concepts neatly, but it is necessary to be aware of the intersection where concepts cross, and clash, when looking at nationhood.

Catabolite repression of phosphoenolpyruvate carboxykinase by a zinc finger protein under biotin- and pyruvate carboxylase-deficient conditions in Pichia pastoris

We have identified a methanol- and biotin-starvation-inducible zinc finger protein named ROP [repressor of phosphoenolpyruvate carboxykinase (PEPCK)] in the methylotrophic yeast Pichia pastoris. When P. pastoris strain GS115 (wild-type, WT) is cultured in biotin-deficient, glucose-ammonium (Bio(-)) medium, growth is suppressed due to the inhibition of anaplerotic synthesis of oxaloacetate, catalysed by the biotin-dependent enzyme pyruvate carboxylase (PC). Deletion of ROP results in a strain (Delta ROP) that can grow under biotin-deficient conditions due to derepression of a biotin- and PC-independent pathway of anaplerotic synthesis of oxaloacetate. Northern analysis as well as microarray expression profiling of RNA isolated from WT and Delta ROP strains cultured in Bio(-) medium indicate that expression of the phosphoenolpyruvate carboxykinase gene (PEPCK) is induced in Delta ROP during biotin- or PC-deficiency even under glucose-abundant conditions. There is an excellent correlation between PEPCK expression and growth of Delta ROP in Bio(-) medium, suggesting that ROP-mediated regulation of PEPCK may have a crucial role in the biotin- and PC-independent growth of the Delta ROP strain. To our knowledge, ROP is the first example of a zinc finger transcription factor involved in the catabolite repression of PEPCK in yeast cells cultured under biotin- or PC-deficient and glucose-abundant conditions.

Regulation of lipid biosynthesis by phosphatidylinositol-specific phospholipase C through the transcriptional repression of upstream activating sequence inositol containing genes

The regulation of phospholipid biosynthesis in Saccharomyces cerevisiae through cis-acting upstream activating sequence inositol (UAS(ino)) and trans-acting elements, such as the INO2-INO4 complex and OPI1 by inositol supplementation in growth is thoroughly studied. In this study, we provide evidence for the regulation of lipid biosynthesis by phosphatidylinositol-specific phospholipase C (PLC) through UAS(ino) and the trans-acting elements. Gene expression analysis and radiolabelling experiments demonstrated that the overexpression of rice PLC in yeast cells altered phospholipid biosynthesis at the levels of transcriptional and enzyme activity. This is the first report implicating PLC in the direct regulation of lipid biosynthesis. (C) 2012 Federation of European Biochemical Societies. Published by Elsevier B.V. All rights reserved.

Transcriptional Repression of Tumor Suppressor CDC73, Encoding an RNA Polymerase II Interactor, by Wilms Tumor 1 Protein (WT1) Promotes Cell Proliferation IMPLICATION FOR CANCER THERAPEUTICS

The Wilms tumor 1 gene (WT1) can either repress or induce the expression of genes. Inconsistent with its tumor suppressor role, elevated WT1 levels have been observed in leukemia and solid tumors. WT1 has also been suggested to act as an oncogene by inducing the expression of MYC and BCL-2. However, these are only the correlational studies, and no functional study has been performed to date. Consistent with its tumor suppressor role, CDC73 binds to RNA polymerase II as part of a PAF1 transcriptional regulatory complex and causes transcriptional repression of oncogenes MYC and CCND1. It also represses beta-catenin-mediated transcription. Based on the reduced level of CDC73 in oral squamous cell carcinoma (OSCC) samples in the absence of loss-of-heterozygosity, promoter methylation, and mutations, we speculated that an inhibitory transcription factor is regulating its expression. The bioinformatics analysis predicted WT1 as an inhibitory transcription factor to regulate the CDC73 level. Our results showed that overexpression of WT1 decreased CDC73 levels and promoted proliferation of OSCC cells. ChIP and EMSA results demonstrated binding of WT1 to the CDC73 promoter. The 5-azacytidine treatment of OSCC cells led to an up-regulation of WT1 with a concomitant down-regulation of CDC73, further suggesting regulation of CDC73 by WT1. Exogenous CDC73 attenuated the protumorigenic activity of WT1 by apoptosis induction. An inverse correlation between expression levels of CDC73 and WT1 was observed in OSCC samples. These observations indicated that WT1 functions as an oncogene by repressing the expression of CDC73 in OSCC. We suggest that targeting WT1 could be a therapeutic strategy for cancer, including OSCC.

The mycobacterial iron-dependent regulator IdeR induces ferritin (bfrB) by alleviating Lsr2 repression

Emerging evidence indicates that precise regulation of iron (Fe) metabolism and maintenance of Fe homeostasis in Mycobacterium tuberculosis (Mtb) are essential for its survival and proliferation in the host. IdeR is a central transcriptional regulator of Mtb genes involved in Fe metabolism. While it is well understood how IdeR functions as a repressor, how it induces transcription of a subset of its targets is still unclear. We investigated the molecular mechanism of IdeR-mediated positive regulation of bfrB, the gene encoding the major Fe-storage protein of Mtb. We found that bfrB induction by Fe required direct interaction of IdeR with a DNA sequence containing four tandem IdeR-binding boxes located upstream of the bfrB promoter. Results of in vivo and in vitro transcription assays identified a direct repressor of bfrB, the histone-like protein Lsr2. IdeR counteracted Lsr2-mediated repression in vitro, suggesting that IdeR induces bfrB transcription by antagonizing the repressor activity of Lsr2. Together, these results elucidate the main mechanism of bfrB positive regulation by IdeR and identify Lsr2 as a new factor contributing to Fe homeostasis in mycobacteria.

A influência do discurso médico no poder punitivo

Esta dissertação discute a relação entre a medicina, a psiquiatria, a psicologia, o poder punitivo e o Direito Penal, bem como a influência que o discurso de uma produziu no outro, e vice versa. Defende a idéia de que a medicina é um espetáculo de poder que, acasalado com o poder punitivo, e interagindo com, e sobre, o indivíduo, invade e se apropria do seu corpo para, usando-o como instrumento de dominação política, discipliná-lo de acordo com a conveniência, sobretudo, da higiene e, naquela sua relação espúria com o poder punitivo, diferenciá-lo e controlá-lo social e penalmente. Sustenta, ainda, que, malgrado o acasalamento não tenha sido intencional, o Estado via na medicina o instrumento para reforçar o seu poder, enquanto essa via naquele o apoio para o seu espraiamento, embora Medicina e Estado tenham convergido, mas também divergido, por vezes tática e estrategicamente, porquanto nem sempre os dois poderes reconheceram o valor da aliança que haviam estabelecido. Então, defende a tese de que o Estado acatou a medicalização das suas ações políticas e admitiu o valor político das ações da medicina, e com vantagens para ambos que, dividindo o poder, conquistaram. É que, a medicina, mais rápida e mais adequada aos problemas salutares apresentados, ajudava-o a se imiscuir no corpo para a permanência parasitária daquela. E, para manter seu direito ao discurso, sustenta que a medicina reinventou constantemente uma necessidade para, diante dela, apresentar-se como única solução, tendo conseguido isso mediante a apresentação de uma retórica dominial eloquente, mas, sobretudo, tecnificada, é dizer, inacessível ao dominado. Com isso, a disciplina, o controle e a repressão do indivíduo, penal e medicamente, estavam prontas, pois, Direito e Medicina, aquele com a lei, esta com o remédio, juntos, dominaram e dominam os destinos do indivíduo, e da coletividade. Demonstrou, ainda, que os higienistas nunca se desocuparam de suas funções. E, por fim, que os princípios penais devem, independente da qualificação que se os dê, sempre refrear o poder punitivo.

Mechanisms of Transposable Element Repression by Piwi Proteins in the piRNA Pathway of Drosophila Germ Cells

The ability to reproduce is a defining characteristic of all living organisms. During reproduction, the integrity of genetic material transferred from one generation to the next is of utmost importance. Organisms have diverse strategies to ensure the fidelity of genomic information inherited between generations of individuals. In sexually reproducing animals, the piRNA pathway is an RNA-interference (RNAi) mechanism that protects the genomes of germ cells from the replication of ‘selfish’ genetic sequences called transposable elements (TE). When left unabated, the replication of TE sequences can cause gene disruption, double-stranded DNA breaks, and germ cell death that results in sterility of the organism. In Drosophila, the piRNA pathway is divided into a cytoplasmic and nuclear branch that involves the functions of three Piwi-clade Argonaute proteins—Piwi, Aubergine (Aub) and Argonaute-3 (Ago3)—which bind piwi-interacting RNA (piRNA) to form the effector complexes that represses deleterious TE sequences.

The work presented in this thesis examines the function and regulation of Piwi proteins in Drosophila germ cells. Chapter 1 presents an introduction to piRNA biogenesis and to the essential roles occupied by each Piwi protein in the repression of TE. We discuss the architecture and function of germ granules as the cellular compartments where much of the piRNA pathway operates. In Chapter 2, we present how Piwi in the nucleus co-transcriptionally targets genomic loci expressing TE sequences to direct the deposition of repressive chromatin marks. Chapter 3 examines the cytoplasmic function of the piRNA pathway, where we find that the protein Krimper coordinates Aub and Ago3 in the piRNA ping-pong pathway to adaptively target and destroy TE transcripts. Chapter 4 explores how interactions of Piwis with associated proteins are modulated by arginine methylation modifications. Lastly, in Chapter 5 I present evidence that the cytoplasmic branch of the piRNA pathway can potentially ‘cross-talk’ with the nuclear branch to transfer sequence information to better target and co-transcriptionally silence the genomic loci coding active TE sequences. Overall, the work presented in this thesis constitutes a part of the first steps in understanding the molecular mechanisms that protect germ cells from invasion by TE sequences.

Mechanisms of E2F2-mediated transcriptional repression

In this work we wanted to study the mechanism of E2F2-mediated repression. Our hypothesis is that E2F2 activates the expression of one or more E2F members of the “repressor” subset of the family through the E2F motifs present in their promoters, and those repressor E2F(s) would subsequently repress the target promoters. To address this hypothesis, we focused on E2F7. E2F7 is a repressor that lacks the Rb binding domain, and associates with DNA through E2F binding sites (de Bruin et al., 2003). Furthermore, E2F7 itself is also regulated by E2F motifs on its own promoter, and it has been shown to repress DNA metabolism and replication genes in late S-phase (de Bruin et al., 2003; Westendorp et al., 2012). E2F7, together with E2F8 has been found to form heterodimers, being critical on cell proliferation and development, and both seem to have similar functions (Li et al., 2008). Preliminary results from Zubiaga’s group have indicated that E2F2 activates E2F7 transcription in U2OS cells, suggesting that E2F2’s repressor function could be mediated by E2F7. For this purpose, we focused on studying E2F7’s role on the target genes previously known to be repressed by E2F2: Chk1 and Mcm5. The specific aims for this work were the following: - Confirm that E2F2 induces E2F7 in HEK-293T cells - Assess whether E2F7 acts as a transcriptional repressor on E2F sites - Evaluate the role of E2F7 on E2F2-mediated transcriptional repression of Chk1 and Mcm5.

Rádice: muito prazer! : crônicas do passado e do futuro da Psicologia no Brasil

O objetivo desta tese é apresentar a revista Rádice revista de psicologia, produzida por psicólogos cariocas entre 1976 e 1981. Esta revista foi de grande importância (intelectual e afetiva) para a geração que, durante o período da ditadura militar brasileira, graduava-se em psicologia. Levava aos seus leitores matérias sobre temas variados e polêmicos, não existentes nas revistas de psicologia da época, como a repressão política, o tratamento desumano nos hospitais psiquiátricos, a regulamentação da profissão de psicologia, as terapias corporais. Participava, com outras publicações nanicas, do Comitê de Imprensa Alternativa, indicando sua participação ativa nos debates políticos ocorridos à época. A Rádice é, pois, um analisador da constituição histórica da psicologia no Brasil, sendo um dos poucos dispositivos de divulgação de outras formas de se fazer psicologia.

Ethnography as a linking method between psychology and sociology: research design

World Conference on Psychology and Sociology 2012
