Residential high-rise buildings in São Paulo: aspects related to the adequacy to the occupant`s needs

This paper analyzes the production of apartment buildings for the middle-income segment in the city of So Paulo, Brazil, from a historical perspective. Tracing the response to the occupants` needs, the focus is on family profiles and their demands, the relationship between architectural design and marketing, and satisfaction levels of current users. The paper begins with a brief historical overview of how apartment buildings have evolved over the past eight decades, highlighting the consolidation of the tripartite model. Next, it analyzes family profiles and their current needs, which would call for a redesign of domestic space. From a different angle, it shows how the real-estate market reacts to this situation, namely by introducing minor changes in the domestic space that are closely linked to major investments in marketing. This leads to a discussion on the quality of recent architectural designs in light of Post-Occupancy Evaluation (POE) case studies, which corroborate the tendencies previously outlined. The conclusions drawn from the POEs suggest that the market should establish a closer and deeper relationship between the assessment of the human behavior in the domestic space and the architectural quality of homes as a means of increasing satisfaction levels and improving design performance.

Controlling cytokinesis in the fission yeast Schizosaccharomyces pombe : the role of dma1; and ubc8

ABSTRACT The fission yeast Schizosaccharomyces pombe is a single celled eukaryote that has proved to be an excellent model system for the study of cell cycle control. S. pombe cells are rod shaped and grow mainly by elongation at their tips. They divide by formation of medially-placed cell wall, or septum, which cleaves the cell in two. Once the cell commits itself to mitosis the site of division is determined by formation of an acto-myosin based contractile ring at the cell cortex. The ring is assembled in stages throughout mitosis and contracts at the end of anaphase, coincident with spindle disassembly. The contraction, but not the assembly, of the ring requires the signal transduction network called the septation initiation network or SIN. The core components of the SIN are three protein kinases (cdc7p, sidl p and sid2p) and their regulatory subunits (spg1 p, cdcl4p and moblp, respectively). Signalling is dependent upon the nucleotide status of the GTPase spgl p, which is regulated by a two-component GAP protein, cdc16p-byr4p. Signalling is thought to emanate from the spindle pole body, where core SIN components are anchored to a scaffold comprised of sid4p and cdc11p. Activation of the SIN requires the protein kinase plolp, which also has additional roles in mitosis. SIN signalling is tightly regulated to assure the proper co-ordination of mitosis and cytokinesis. Ectopic activation of the SIN in interphase can uncouple septum formation from mitosis, while deregulated SIN signalling leads to formation of cells with multiple septa that do not cleave. Regulators of SIN activity are therefore of considerable interest. This study has concentrated upon two of these, dma1 and ubc8. I have demonstrated that dmal becomes essential when SIN signalling is activated. This leads me to propose a tripartite model for regulation of the SIN during the mitotic cell cycle. Increased expression of dma1 inhibits SIN signalling and prevents cell division. To identify potential targets and mediators of this, multicopy suppressors of dma1 toxicity were identified. One of these, ubc8, is the subject of this thesis. Genetic and molecular analyses are consistent with the view that ubc8p acts as an inhibitor of the SIN Localisation of ubc8p indicates that it is a nuclear protein. The ubc8 gene is not essential, but in its absence cells are unable to prevent septum formation if progression through mitosis is impaired. These data suggest that it may be an effector of the spindle assembly checkpoint. Together, these data shed new light upon the mechanisms by which cytokinesis is regulated in S. pombe. RESUME La levure Schizosaccharomyces pombe est un eucaryote unicellulaire qui est un bon système d'étude du cycle cellulaire. Les cellules de S. pombe sont en forme de bâtonnets et poussent par allongement aux deux bouts. Elles se divisent en formant une paroi au milieu de la cellule, qui s'appelle un septum et qui sépare la cellule en deux. Une fois que la cellule est engagée dans la mitose, le site de clivage est déterminé par la formation d'un anneau contractile d'acto-myosine au niveau du cortex cellulaire. Cet anneau est séquentiellement assemblé au cours de la mitose et se contacte à la fin de l'anaphase, au moment où le fuseau mitotique et désassemblé. La contraction, mais non pas l'assemblage, de l'anneau dépend d'un réseau de signalisation appelé septation initiation netvvork' ou SIN. Les composants centraux du SIN sont trois kinases (cdc7, sidi et sid2) ainsi que leurs sous-unités régulatrices (spgl, cdc14 et mob1, respectivement). La signalisation dépend du nucléotide rattaché à la GTPase spgl qui est régulée par une GAP comprenant deux sous-unités cdc16 et byr4. La signalisation est présumée provenir du pôle du fuseau où les composants centraux du SIN sont ancrés grâce à un échafaudage comprenant sid4 et cdcl 1. La signalisation est étroitement régulée pour assurer une bonne coordination entre mitose et cytokinèse. Une activation ectopique du SIN en interphase peut découpler la formation du septum de la mitose, engendrant des cellules à multiples septa qui ne sont pas clivés. C'est pourquoi les régulateurs du SIN sont d'un intérêt considérable. Cette étude se concentre autour de deux ces régulateurs, dma1 et ubc8. J'ai montré que dma1 devient essentiel quand la signalisation du SIN est activée. Ceci m'amène à proposer un modèle en trois parties pour la régulation du SIN durant la mitose. Une expression élevée de dma1 inhibe la signalisation du SIN et empêche la division cellulaire. Afin d'identifier des substrats ou médiateurs potentiels de la toxicité de dma1, des supresseurs en copies multiples ont été identifiés. Un de ces supresseurs, ubc8, constitue le deuxième sujet de cette thèse. Les études génétiques et moléculaires suggèrent un rôle inhibiteur du SIN par ubc8. Ubc8p est une protéine nucléaire, non essentielle, mais en son absence les cellules ne peuvent pas restreindre la fomation du septum, lorsque la progression de la mitose est perturbée. Les données suggèrent que ubc8 pourrait être un effecteur de point de contrôle de l'assemblage du fuseau mitotique. Prises dans leur ensemble, ces données apportent un nouvel éclairage sur les mécanismes de régulation de la cytokinèse dans S. pombe.

Psychometric properties of the Portuguese version of the State-Trait Anxiety Inventory applied to college students: factor analysis and relation to the Beck Depression Inventory

The psychometric properties of the Portuguese version of the trait form of the State-Trait Anxiety Inventory (STAI-T) and its relation to the Beck Depression Inventory (BDI) were evaluated in a large Brazilian college student sample containing 845 women and 235 men. STAI-T scores tended to be higher for women, singles, those who work, and subjects under 30 years. Factor analysis of the STAI-T for total sample and by gender yielded two factors: the first representing a mood dimension and the second being related to worrying or cognitive aspects of anxiety. In order to study the relation between anxiety and depression measures, factor analysis of the combination of the 21 BDI items and the 20 STAI-T items was also carried out. The analysis resulted in two factors that were analyzed according to the tripartite model of anxiety and depression. Most of the BDI items (measuring positive affectivity and nonspecific symptoms of depression) were loaded on the first factor and four STAI-T items that measure positive affectivity. The remaining STAI-T items, all of them measuring negative affect, remained in the second factor. Thus, factor 1 represents a depression dimension and factor 2 measures a mood-worrying dimension. The findings of this study suggest that, although widely used as an anxiety scale, the STAI-T in fact measures mainly a general negative affect.

Social class as a factor for the construction of a musician’s identity : The Musician’s social background and identity questionnaire (MSBIQ) – a cross-sectional comparative quantitative online survey research study of music students at two higher education institutions in Finland

There is currently little empirical knowledge regarding the construction of a musician’s identity and social class. With a theoretical framework based on Bourdieu’s (1984) distinction theory, Bronfenbrenner’s (1979) theory of ecological systems, and the identity theories of Erikson (1950; 1968) and Marcia (1966), a survey called the Musician’s Social Background and Identity Questionnaire (MSBIQ) is developed to test three research hypotheses related to the construction of a musician’s identity, social class and ecological systems of development. The MSBIQ is administered to the music students at Sibelius Academy of the University of Arts Helsinki and Helsinki Metropolia University of Applied Sciences, representing the ’highbrow’ and the ’middlebrow’ samples in the field of music education in Finland. Acquired responses (N = 253) are analyzed and compared with quantitative methods including Pearson’s chi-square test, factor analysis and an adjusted analysis of variance (ANOVA). The study revealed that (1) the music students at Sibelius Academy and Metropolia construct their subjective musician’s identity differently, but (2) social class does not affect this identity construction process significantly. In turn, (3) the ecological systems of development, especially the individual’s residential location, do significantly affect the construction of a musician’s identity, as well as the age at which one starts to play one’s first musical instrument. Furthermore, a novel finding related to the structure of a musician’s identity was the tripartite model of musical identity consisting of the three dimensions of a musician’s identity: (I) ’the subjective dimension of a musician’s identity’, (II) ’the occupational dimension of a musician’s identity’ and, (III) ’the conservative-liberal dimension of a musician’s identity’. According to this finding, a musician’s identity is not a uniform, coherent entity, but a structure consisting of different elements continuously working in parallel within different dimensions. The results and limitations related to the study are discussed, as well as the objectives related to future studies using the MSBIQ to research the identity construction and social backgrounds of a musician or other performing artists.

Impacto de la auto - percepción de imagen corporal en sujetos con VIH y lipoatrofia facial.

La lipoatrofia facial es uno de los efectos secundarios que con más frecuencia se presenta y afecta la calidad de vida del paciente con VIH que recibe tratamiento antiretroviral. Metodología: Estudio observacional de corte transversal que involucró 126 sujetos, a quienes se aplicó una encuesta semi-estructurada para determinar cómo percibe el paciente que la lipoatrofia facial lo afecta en áreas afectiva, social, laboral y ocupacional; evaluar la percepción de la imagen corporal; caracterizar sociodemográficamente; determinar la prevalencia de lipoatrofia facial y establecer si hay diferencias de percepción de la imagen corporal según la caracterización sociodemográfica. Resultados: La Prevalencia de lipoatrofia facial fue del 57.1%. El grado de satisfacción en cuanto a apariencia física tuvo un promedio de 5.01±2.69. El 88.7% y 80.3% de los pacientes evaluados sintieron tristeza y frustración con su apariencia respectivamente. El 53.5% y el 42.9% informaron menos oportunidades laborales y educativas. La orientación sexual reportada con mayor frecuencia fue homosexualidad. No hubo diferencias estadísticamente significativas entre el grado de satisfacción de apariencia con aspectos sociodemográficos excepto en pacientes que recibieron apoyo psicológico. Conclusión: Primer estudio en el país que evalúa el impacto de la lipoatrofia facial en pacientes con VIH y tratamiento antiretroviral. Aunque la presencia de lipoatrofia facial sobre la cotidianidad no es estadísticamente significativa, si resulta trascendental pues existen porcentajes importantes de emociones y alteraciones psicológicas que afectan directamente a estos sujetos en las áreas afectiva, social, laboral y ocupacional. Se hace necesaria la realización de más estudios que permitan obtener mayor de evidencia.

Actitudes hacia el VIH/SIDA, el cáncer y la enfermedad de Alzheimer

Esta revisión de la literatura tuvo como objetivo describir las actitudes hacia el VIH/SIDA, el cáncer y la Enfermedad de Alzheimer desde el modelo tripartito. Se revisaron 109 artículos publicados entre 2005 y 2015 en algunas bases de datos especializadas y herramientas de análisis de impacto. También se incluyeron fuentes secundarias ampliándose la búsqueda a los últimos 20 años (1995-2015). Los resultados mostraron que la mayoría de los estudios realizados sobre las actitudes hacia estas tres enfermedades son de tipo cuantitativo y la información se analizó con base en los componentes del modelo tripartito. Algunos aspectos sociodemográficos como el sexo y la edad están asociados con las actitudes hacia las tres enfermedades y predominan las creencias erróneas sobre ellas respecto a sus causas, curso y tratamiento. También predominan actitudes negativas hacia las tres enfermedades y las conductas e intenciones conductuales son diversas hacia cada una de ellas. No se hallaron antecedentes empíricos del estudio de la estructura de las actitudes propuesta por el modelo tripartito hacia las tres enfermedades. La Salud Pública ha liderado la investigación con base en el modelo de conocimientos, actitudes y prácticas propuesto por la OMS.

Factor structure of the Mood and Anxiety Symptom Questionnaire does not generalize to an anxious/depressed sample

Objective: The tripartite model of anxiety and depression has been proposed as a representation of the structure of anxiety and depression symptoms. The Mood and Anxiety Symptom Questionnaire (MASQ) has been put forwards as a valid measure of the tripartite model of anxiety and depression symptoms. This research set out to examine the factor structure of anxiety and depression symptoms in a clinical sample to assess the MASQ's validity for use in this population. MethodsThe present study uses confirmatory factor analytic methods to examine the psychometric properties of the MASQ in 470 outpatients with anxiety and mood disorder. Results: The results showed that none of the previously reported two-factor, three-factor or five-factor models adequately fit the data, irrespective of whether items or subscales were used as the unit of analysis. Conclusions: It was concluded that the factor structure of the MASQ in a mixed anxiety/depression clinical sample does not support a structure consistent with the tripartite model. This suggests that researchers using the MASQ with anxious/depressed individuals should be mindful of the instrument's psychometric limitations.

Actitudes hacia la Enfermedad del Alzheimer según el género y la edad de adultos colombianos

La enfermedad de Alzheimer (EA) es la demencia más frecuente y su prevalencia continúa en aumento tanto en Colombia como en el mundo. Esta investigación tuvo como objetivo explorar si las actitudes hacia la EA varían según la edad y género de 450 personas adultas colombianas. Se realizó un estudio exploratorio de corte transversal en el que se aplicó un cuestionario autodiligenciado. Se encontró que efectivamente hay algunas diferencias según la edad y el género en el componente cognoscitivo (creencias y conocimiento) y conductual (intención conductual y conducta) de las actitudes; y diferencias según el género en el componente afectivo. Se concluye que los conocimientos sobre la EA son escasos, que la tristeza es la emoción predominante hacia la EA y que es un tema de interés en el que predomina la idea de que afecta especialmente la memoria. Se discutieron los resultados reconociendo que esta es una aproximación inicial a las actitudes hacia la EA.

Santé mentale, alcool/drogues et violence : adaptation du modèle tripartite de Goldstein.

Plusieurs recherches démontrent que le fait de présenter un trouble mental sévère et un trouble concomitant lié à une substance serait associé à un risque plus élevé de comportements violents. Toutefois, il n’existe aucun modèle conceptuel expliquant la relation entre ce type de comorbidité psychiatrique et la violence. Cet article propose une première explication du phénomène basée sur une adaptation des volets psychopharmacologique et économicocompulsif du modèle tripartite de Goldstein, à la population atteinte d’un trouble mental sévère et persistant (la schizophrénie ou la maladie bipolaire) et d’un trouble concomitant lié à une substance.

Quantitative aspects of entanglement in the driven Jaynes-Cummings model

Adopting the framework of the Jaynes-Cummings model with an external quantum field, we obtain exact analytical expressions of the normally ordered moments for any kind of cavity and driving fields. Such analytical results are expressed in the integral form, with their integrands having a commom term that describes the product of the Glauber-Sudarshan quasiprobability distribution functions for each field, and a kernel responsible for the entanglement. Considering a specific initial state of the tripartite system, the normally ordered moments are then applied to investigate not only the squeezing effect and the nonlocal correlation measure based on the total variance of a pair of Einstein-Podolsky-Rosen type operators for continuous variable systems, but also the Shchukin-Vogel criterion. This kind of numerical investigation constitutes the first quantitative characterization of the entanglement properties for the driven Jaynes-Cummings model.

Analog Modeling of Human Cognitive Functions with Tripartite Synapses

Searching for an understanding of how the brain supports conscious processes, cognitive scientists have proposed two main classes of theory: Global Workspace and Information Integration theories. These theories seem to be complementary, but both still lack grounding in terms of brain mechanisms responsible for the production of coherent and unitary conscious states. Here we propose following James Robertson's "Astrocentric Hypothesis" - that conscious processing is based on analog computing in astrocytes. The "hardware" for these computations is calcium waves mediated by adenosine triphosphate signaling. Besides presenting our version of this hypothesis, we also review recent findings on astrocyte morphology that lend support to their functioning as Local Hubs (composed of protoplasmic astrocytes) that integrate synaptic activity, and as a Master Hub (composed, in the human brain, by a combination of interlaminar, fibrous, polarized and varicose projection astrocytes) that integrates whole-brain activity.

Integrated Proteomics Identified Up-regulated Focal Adhesion-mediated Proteins In Human Squamous Cell Carcinoma In An Orthotopic Murine Model.

Understanding the molecular mechanisms of oral carcinogenesis will yield important advances in diagnostics, prognostics, effective treatment, and outcome of oral cancer. Hence, in this study we have investigated the proteomic and peptidomic profiles by combining an orthotopic murine model of oral squamous cell carcinoma (OSCC), mass spectrometry-based proteomics and biological network analysis. Our results indicated the up-regulation of proteins involved in actin cytoskeleton organization and cell-cell junction assembly events and their expression was validated in human OSCC tissues. In addition, the functional relevance of talin-1 in OSCC adhesion, migration and invasion was demonstrated. Taken together, this study identified specific processes deregulated in oral cancer and provided novel refined OSCC-targeting molecules.
