A pesquisa em psicologia: ensaio sobre a Psicologia enquanto ciência, a pesquisa qualitativa e o uso da entrevista como principal instrumento de coleta de dados

For constituting itself a science, Psychology has coursed along way. From the time he was considered a Philosophy’s discipline until to be recognized as a legitimate science, Psychology had to devoteto the definition of its object of study, the development and refinement of theoretical-methodological frameworks and, in particular, to consolidation process of their research strategies and knowledge construction. Therefore, in order to regard the demands of the classical scientific paradigm, which is very influenced by Positivism, Psychology made use, initially, of quantitative methodology and laboratory research. This article presents some of the process of identity construction of Psychology as a science, focusing on its transition path between the quantitativist paradigm of scientific knowledge production to the qualitativist paradigm, until that is more commonly practiced nowadays: the collaborative use of these methodological strategies. For presenting the qualitative researching Psychology, we discussed, beyond its proposal and differentiation elements in relation to quantitative research, the different methods used for this mode and, in particular, the interview - which is considered the main way of data collection in surveys conducted by psychologists and, therefore, it is an important element the process of knowledge building that science, in addition to being the most qualified space for dialogue between there searcher and the research subject.

Um olhar epistemológico sobre o vocábulo ambiente: algumas contribuições para pensarmos a ecologia e a educação ambiental

After the presentation of semantic and etymological considerations given to the word environment, this paper discusses how this term was appropriated and re-signified in different historical moments. Based on previous studies, it is noted that there were two appropriations of the word environment: one whose origin was in the Natural Sciences and one that would be related to the Human Sciences. At the end is argued that such appropriations can be found today, respectively, in Ecology and Environmental Education

As dificuldades para a gestão do PIBID a partir do olhar de coordenadores e colaboradores em subprojetos na Faculdade de Ciências Bauru: limites e possibilidades

The Institutional Program of Initiation to Teaching, the PIBID, has by its nature the training of teachers. Focused on graduate students, the PIBID acts as a proposal for training beyond the mandatory classes, giving to the students that are entering the program, a great opportunity to improve their training as a teacher. Thus, this work focuses on a discussion of the PIBID at the Faculty of Sciences UNESP Bauru, aimed at subprojects of graduate students linked to the areas of Natural Sciences, Mathematics, Physics, Biology and Chemistry, working in an interdisciplinary way. I interviewed five teachers (three area coordinators and two contributors) seeking to verify, in their view, the understanding about the program and what were the major difficulties in the training of teachers. For contributors teachers and coordinators of the subprojects, interdisciplinarity has a very important role in the training of new teachers, and the PIBID allows to work this concept more broadly than just in the mandatory classes. However, a program so big like the PIBID comes with problems and it is in this context that this study was conducted. Coordinator teachers and contributors of the subprojects identified flaws in the program that may affect the activities proposed in the institutional design

O uso do diário de campo na inserção ecológica em uma família de uma comunidade ribeirinha amazônica

O presente estudo visa demonstrar a utilização do diário de campo em pesquisas realizadas em contexto natural sob a perspectiva do modelo bioecológico de Bronfenbrenner. Para efeito de ilustração, são apresentados dados que fizeram parte da pesquisa de mestrado da primeira autora sobre as percepções de uma família com uma criança com deficiência intelectual no contexto ribeirinho amazônico. Após a coleta das informações, os dados foram organizados com base nos conceitos propostos por Bronfenbrenner. O diário de campo permitiu o aprofundamento das análises em que foram contemplados tanto os aspectos contextuais (cultura ribeirinha amazônica), como os pessoais (características biossociopsicológicas da criança/pais) e os processuais (relações, papéis familiares e atividades compartilhadas). Os dados são discutidos considerando a contribuição do diário de campo nas pesquisas que investigam famílias em seu contexto.

Zoonotic Diseases in the Changing Arctic

Compatible with the biotic uniformity of northern regions, the occurrence of certain organisms which cause zoonotic diseases is general throughout the Arctic. In the past, most frequently affected by such diseases have been aboriginal peoples whose way of life involved encroachment upon naturally occurring parasite-host assemblages. Now, as changes take place in socioeconomic conditions in the Arctic, the importance of zoonotic diseases as a cause of morbidity may lessen among such peoples, but on the other hand, more nonaborigines may be affected. Although my remarks relate mainly to Alaska, again the biotic uniformity of the North seems to have its effect even with regard to man's activity, for similar changes are occurring throughout the arctic zone. Thus far, the natural environment has not been extensively disrupted at higher latitudes, and the arctic regions remain important for basic research in the natural history of zoonotic diseases. Because of the biotic peculiarities of these regions, conditions there especially favor the investigation of parasite-host relationships and the transmission of disease among the inhabitants. Significant benefit to the human population, in the temperate zone as well, can be expected to accrue from future studies in an undisturbed arctic wilderness.

Taxonomic revision of extant Doras Lacepede, 1803 (Siluriformes: Doradidae) with descriptions of three new species

Extant Doras are newly diagnosed among Doradidae by the unique combination of maxillary barbels long and fimbriate; mesethmoid with anterior lateral margins converging towards narrow tip; single anterior cranial fontanel contained largely within frontals and anteriorly by mesethmoid (posterior cranial fontanel occluded); anterior nuchal plate wide, pentaganol or roughly hexagonal, sharing distinct lateral suture with epioccipital and isolating supraoccipital from middle nuchal plate; nuchal foramina absent; coracoid process short, posterior tip falling well short of that of postcleithral process; dentary with acicular teeth; and skin immediately ventral to postcleithral process perforated with conspicuous pores. One fossil species, dagger D. dioneae, and two nominal extant species, D. carinatus and D. micropoeus, are recognized as valid and the latter two redescribed. Three additional extant species, D. phlyzakion, D. higuchii and D. zuanoni, are newly described from the middle Amazon and tributaries, lower Amazon tributaries and rio Araguaia (Tocantins drainage), respectively. Doras phlyzakion and D. zuanoni form a monophyletic group that is found in lowland, lentic habitats, and is characterized by multiple conspicuous pores in skin on breast and abdomen, a trait unique among doradids and rare if not unique among all catfishes. The remaining extant species, D. carinatus, D. higuchii and D. micropoeus, with uncertain relationships, are found in upland, lotic habitats. The occurrence of D. carinatus in the Orinoco basin suggests a historical link between right-bank tributaries of the lower Orinoco (e.g., Caroni) draining the western Guiana Shield and more eastern rivers (e.g., Cuyuni-Essequibo) that drain the Shield directly into the Atlantic Ocean. A key to extant species is provided, a neotype is designated for Silurtis carinatus Linnaeus 1766, and Mormyropsis Miranda Ribeiro, 1911, is placed in the synonymy of Doras Lacepede, 1803.

Two-dimensional semimetal-insulator transition in HgTe-based quantum wells induced by a longitudinal magnetic field

A metal-insulator transition in a two-dimensional semimetal based on HgTe quantum wells is discovered. The transition is induced by a magnetic field applied parallel to the plane of the quantum well. The threshold behavior of the activation energy as a function of the magnetic-field strength and an abrupt reduction of the Hall resistance at the onset of the transition suggest that the observed effect originates from the formation of an excitonic insulator.

EVALUATION OF IN VITRO AND IN VIVO EFFECTS OF SEMIPURIFIED PROTEINASE INHIBITORS FROM THEOBROMA SEEDS ON MIDGUT PROTEASE ACTIVITY OF LEPIDOPTERAN PEST INSECTS

We have characterized in vitro and in vivo effects of trypsin inhibitors from Theobroma seeds on the activity of trypsin- and chymotrypsin-like proteins from Lepidopteran pest insects. The action of semipurified trypsin inhibitors from Theobroma was evaluated by the inhibition of bovine trypsin and chymotrypsin activities determined by the hydrolysis of N-Benzoyl-DL-Arginine-p-Nitroanilide (BAPA) and N-Succinyl-Ala-Ala-Pho-Phe p-Nitroanilide (S-(Ala)2ProPhe-pNA). Proteinase inhibitor activities from Theobroma cacao and T. obovatum seeds were the most effective in inhibiting trypsin-like proteins, whereas those from T. obovatum and T. sylvestre were the most efficient against chymotrypsin-like proteins. All larvae midgut extracts showed trypsin-like proteolytic activities, and the putative trypsin inhibitors from Theobroma seeds significantly inhibited purified bovine trypsin. With respect to the influence of Theobroma trypsin inhibitors on intact insects, the inclusion of T. cacao extracts in artificial diets of velvet bean caterpillars (Anticarsia gemmatalis) and sugarcane borer (Diatraea saccharalis) produced a significant increase in the percentage of adult deformation, which is directly related to both the survival rate of the insects and oviposition.

Iheringichthys syi (Siluriformes: Pimelodidae), a new pimelodid species from upper Paraná basin, Brazil

We describe a new species of pimelodid catfish of the genus Iheringichthys from the upper Paraná basin, Brazil. Iheringichthys syi n. sp. is distinguished by the comparatively fine serration along the anterior margin of the pectoral-fin spine, an adpressed dorsal-fin remote from the adipose-fin origin, a large eye (23.2-31.2% of head length), narrow interorbital (16.2-23.0% of head length), long snout (42.0-51.0% of head length), long postorbital length (30.6-34.0% of head length), low adipose fin (4.8-7.8% of standard length), eye diameter 97.0-140.0% of interorbital length, and body with numerous, small dots irregularly scattered on flanks, especially marked on anterior half of flank.

Untersuchungen zur induzierbaren Expression des Adhäsionsmoleküls E-Selektin und dessen potentieller Bedeutung bei der Tumormetastasierung

In der vorliegenden Arbeit konnte gezeigt werden, dass sowohl die durch TNFalpha-, als auch durch Röntgenstrahlen vermittelte Expression des Adhäsionsmoleküls E-Selektin in Endothelzellen durch kleine GTPasen der Rho-Proteinfamilie reguliert ist. Hemmung dieser kleinen G-Proteine z.B. durch HMG-CoA Reduktase-Inhibitoren (Statine) oder clostridiale Toxine führt zu verminderter Expression von E-Selektin in humanen Endothelzellen (HUVEC; EA.hy-926). Aus den in der Arbeit erhaltenen Ergebnissen kann außerdem die Schlussfolgerung gezogen werden, dass die Regulation der zytokininduzierten E-Selektin-Genexpression von der gamma-Strahlen-vermittelten Expression des E-Selektingens differiert. Für die strahleninduzierte endotheliale E-Selektin-Expression scheint beispielsweise der Transkriptionsfaktor AP-1 als ein weiterer Kontrollfaktor neben NF-kappaB zu fungieren. Des Weiteren konnte in der vorliegenden Arbeit gezeigt werden, dass eine gesteigerte E-Selektin-Proteinexpression mit erhöhter Tumorzelladhäsion und -transmigration an bzw. durch humane Endothelzellen korreliert. Hemmung der TNFalpha- bzw. gamma-Strahlen-induzierten Expression von E-Selektin durch Statine oder Retinsäuren ist ausreichend, sowohl Tumorzelladhäsion als auch Tumorzelldiapedese zu reduzieren. Zusammenfassend lässt sich festhalten, dass das Adhäsionsmolekül E-Selektin eine vielversprechende Zielstruktur ist, über deren kontrollierte Beeinflussung es auch in vivo möglich sein sollte, das Risiko der Metastasierung zu reduzieren. Mit Statinen und Retinsäurederivaten wurden somit Pharmaka identifiziert, die durch Hemmung der Rho-regulierten E-Selektin-Expression der Tumorzellmetastasierung vorbeugen könnten. Um diese Hypothese in zukünftigen tierexperimentelle Studien zu bestätigen, wurde im Rahmen dieser Arbeit mit der Generierung transgener Tiermodelle begonnen.

Untersuchungen zur Visuomotorik des Menschen

Motorische Bewegungen werden über die visuelle Rückmeldung auf ihre Genauigkeit kontrolliert und ggf. korrigiert. Über einen technischen Eingriff, wie beispielsweise einer Prismenbrille, kann man eine Differenz zwischen optisch wahrgenommener und haptisch erlebter Umwelt erzeugen, um die Fähigkeiten des visuomotorischen Systems zu testen. In dieser Arbeit wurde eine computergestützte Methode entwickelt, eine solche visuomotorische Differenz zu simulieren. Die Versuchspersonen führen eine ballistische Bewegung mit Arm und Hand aus in der Absicht, ein vorgegebenes Ziel zu treffen. Die Trefferpunkte werden durch einen Computer mit Hilfe eines Digitalisierungstablettes aufgenommen. Die visuelle Umwelt, welche den Versuchspersonen präsentiert wird, ist auf einem Monitor dargestellt. Das Monitorabbild – ein Kreuz auf weißem Hintergrund – betrachten die Testpersonen über einen Spiegel. Dieser ist in einem entsprechenden Winkel zwischen Monitor und Digitalisierungstablett angebracht, so dass das Zielbild auf dem Digitalisierungstablett projiziert wird. Die Testpersonen nehmen das Zielkreuz auf dem Digitalisierungstablett liegend wahr. Führt die Versuchsperson eine Zielbewegung aus, können die aufgenommenen Koordinaten als Punkte auf dem Monitor dargestellt werden und die Testperson erhält über diese Punktanzeige ein visuelles Feedback ihrer Bewegung. Der Arbeitsbereich des Digitalisierungstabletts kann über den Computer eingerichtet und so motorische Verschiebungen simuliert werden. Die verschiedenartigen Möglichkeiten dieses Aufbaus wurden zum Teil in Vorversuchen getestet um Fragestellungen, Methodik und technische Einrichtungen aufeinander abzustimmen. Den Hauptversuchen galt besonderes Interesse an der zeitlichen Verzögerung des visuellen Feedbacks sowie dem intermanuellen Transfer. Hierbei ergaben sich folgende Ergebnisse: ● Die Versuchspersonen adaptieren an eine räumlich verschobene Umwelt. Der Adaptationsverlauf lässt sich mit einer Exponentialfunktion mathematisch berechnen und darstellen. ● Dieser Verlauf ist unabhängig von der Art des visuellen Feedbacks. Die Beobachtung der Handbewegung während der Adaptation zeigt die gleiche Zielabfolge wie eine einfache Punktprojektion, die den Trefferort der Bewegung darstellt. ● Der exponentielle Verlauf der Adaptationsbewegung ist unabhängig von den getesteten zeitlichen Verzögerungen des visuellen Feedbacks. ● Die Ergebnisse des Folgeeffektes zeigen, dass bei zunehmender zeitlicher Verzögerung des visuellen Feedbacks während der Adaptationsphase, die Größe des Folgeeffektwertes geringer wird, d.h. die anhaltende Anpassungsleistung an eine visuomotorische Differenz sinkt. ● Die Folgeeffekte weisen individuelle Eigenheiten auf. Die Testpersonen adaptieren verschieden stark an eine simulierte Verschiebung. Ein Vergleich mit den visuomotorischen Herausforderungen im Vorleben der Versuchspersonen ließ vermuten, dass das visuomotorische System des Menschen trainierbar ist und sich - je nach Trainingszustand – unterschiedlich an wahrgenommene Differenzen anpasst. ● Der intermanuelle Transfer konnte unter verschiedenen Bedingungen nachgewiesen werden. ● Ein deutlich stärkerer Folgeeffekt kann beobachtet werden, wenn die wahrgenommene visuomotorische Differenz zwischen Ziel und Trefferpunkt in eine Gehirnhälfte projiziert wird und der Folgeeffekt mit der Hand erfolgt, welche von dieser Hirnhemisphäre gesteuert wird. Der intermanuelle Transfer wird demnach begünstigt, wenn die visuelle Projektion der Fehlerbeobachtung in die Gehirnhälfte erfolgt, die während der Adaptationsphase motorisch passiv ist.
