As fontes do método analítico de leitura de João Köpke (1896-1917)

After two decades advertising and defending the synthetic method, João Köpke became active disseminator of analytical method for teaching reading. In five te xts published between 1896 and 1917, produced in different circumstance s for different publics readers, Köpke seeks the support of American and European authors, for their principles as well as for the education experience, to his analytical method. as by theirs principles as by theirs educational experiences. Among those authors: J. Jacotot, A. Bain, A. Meiklejohn, J. Froebel, C. Parker, G. Stanley Hall and J. Chubb. In this article, attention is given to repeated American references with special emphasis on the psychology of Stanley Hall and the method of teaching reading of Meiklejohn, highlighted and placed on convergence by Köpke in his final writings.

The Brazilian National Health Agency and the Mental Health Policy in the Context of the Private Health System: developments and challenges

This work analyses the mental health policy-making activity of the Brazilian National Health Agency (ANS), responsible for controlling health insurance companies. Three points are discussed: a) the framework of an economic and private health assistance regulatory activity, b) the ANS and its regulation activity and c) the rules produced by ANS in the mental health care field. It was concluded that, despite advances like the legal obligation to ensure medical treatment to all the diseases listed in ICD-10, the inclusion of suicidal patient damage and self-inflicted damage care, care provided by a multiprofessional team, the increase in the number of sessions with a psychologist, with an occupational therapist and of psychotherapy sessions, and mental health day hospitals included as part of the services offered, the authors identified specific regulatory gaps in this area. Some issues that ANS has to solve so that it can really play its institutional role of defending the public interest in the private health system are: the regulation of co-participation and franchise mechanisms, the increasing co-participation as a limitation of psychiatric hospitalization, and the limited number of crisis intervention psychotherapy sessions.

Purification and characterization of Hb 98-114: A novel hemoglobin-derived antimicrobial peptide from the midgut of Rhipicephalus (Boophilus) microplus

The antimicrobial activity of hemoglobin fragments (hemocidins) has been reported in a variety of models. The cattle tick Rhipicephalus (Boophilus) microplus is a blood sucking arthropod from where the first in vivo-generated hemocidin was characterized (Hb 33-61). In the present work we identified a novel antimicrobial peptide from the midgut of fully engorged R. (B.) microplus females, which comprises the amino acids 98-114 of the alpha subunit of bovine hemoglobin, and was designated Hb 98-114. This peptide was active against several yeast and filamentous fungi, although no activity was detected against bacteria up to 50 mu M of the synthetic peptide. Hb 98-114 was capable of permeabilizing Candida albicans cell membrane and had a fungicidal effect against this yeast. Circulardichroism (CD) and nuclear magnetic resonance (NMR) experiments showed that Hb 98-114 has a random conformation in aqueous solution but switches to an alpha-helical conformation in the presence of sodium dodecyl sulfate (SDS). This alpha helix adopts an amphipathic structure which may be the mechanism of cell membrane permeabilization. Importantly, Hb 98-114 may play an important role in defending the tick midgut against fungal pathogens and is the first hemocidin with specific antifungal activity to be characterized.

Role of xanthophyll and water-water cycles in the protection of photosynthetic apparatus in Arbutus unedo and Arabidopsis thaliana

Photosynthetic organisms have sought out the delicate balance between efficient light harvesting under limited irradiance and regulated energy dissipation under excess irradiance. One of the protective mechanisms is the thermal energy dissipation through the xanthophyll cycle that may transform harmlessly the excitation energy into heat and thereby prevent the formation of damaging active oxygen species (AOS). Violaxanthin deepoxidase (VDE) converts violaxanthin (V) to antheraxanthin (A) and zeaxanthin (Z) defending the photosynthetic apparatus from excess of light. Another important biological pathway is the chloroplast water-water cycle, which is referred to the electrons from water generated in PSII reducing atmospheric O2 to water in PSI. This mechanism is active in the scavenging of AOS, when electron transport is slowed down by the over-reduction of NADPH pool. The control of the VDE gene and the variations of a set of physiological parameters, such as chlorophyll florescence and AOS content, have been investigated in response to excess of light and drought condition using Arabidopsis thaliana and Arbutus unedo.. Pigment analysis showed an unambiguous relationship between xanthophyll de-epoxidation state ((A+Z)/(V+A+Z)) and VDE mRNA amount in not-irrigated plants. Unexpectedly, gene expression is higher during the night when xanthophylls are mostly epoxidated and VDE activity is supposed to be very low than during the day. The importance of the water-water cycle in protecting the chloroplasts from light stress has been examined through Arabidopsis plant with a suppressed expression of the key enzyme of the cycle: the thylakoid-attached copper/zinc superoxide dismutase. The analysis revealed changes in transcript expression during leaf development consistent with a signalling role of AOS in plant defence responses but no difference was found any in photosynthesis efficiency or in AOS concentration after short-term exposure to excess of light. Environmental stresses such as drought may render previously optimal light levels excessive. In these circumstances the intrinsic regulations of photosynthetic electron transport like xanthophyll and water-water cycles might modify metabolism and gene expression in order to deal with increasing AOS.

L'accertamento dei reati di guida in stato di ebbrezza e alterazione da droghe

La tesi affronta le questioni processuali connesse alla verifica dei reati di guida in stato di ebbrezza e di alterazione da droghe. La ricerca si sviluppa in tre direzioni. La prima parte studia la disciplina tedesca. L’analisi parte dalle norme sostanziali che definiscono le fattispecie incriminatrici contemplate dall’ordinamento osservato; s’interessa, poi, degli equilibri tra gli strumenti di captazione della prova utili ai reati in discorso ed il principio nemo tenetur se detegere (l’ estensione del diritto di difesa tedesco copre anche le prove reali e non prevede obblighi di collaborazione all’alcoltest). Prosegue, infine, con l’esame delle metodologie di acquisizione della prova, dall’etilometro agli screening per le droghe, sino al prelievo ematico coattivo, indispensabile per l’accertamento penale. La seconda sezione esamina gli artt. 186 e 187 del codice della strada italiano, alla luce del principio di libertà personale e del diritto a non autoincriminarsi. Particolarmente delicati gli equilibri rispetto a quest’ultimo: l’obbligatorietà di un atto potenzialmente autoaccusatorio è evitabile solo a pena di una severa sanzione. Occorre definire se il diritto di difesa copra anche il mero facere o garantisca il solo silenzio. Se si ammette, infatti, che il nemo tenetur sia applicabile anche alle prove reali, la collaborazione obbligatoria imposta al conducente è scelta incompatibile con il diritto di difesa: la disciplina italiana presenta, dunque, profili d’illegittimità costituzionale. La terza parte riguarda le problematiche processuali poste dai controlli stradali che emergono dall’analisi della giurisprudenza. Si affrontano, così, le diverse vicende della formazione della prova: ci si interroga sull’istituto processuale cui ricondurre gli accertamenti, sulle garanzie di cui goda il guidatore durante e dopo l’espletamento dell’atto, sulle eventuali sanzioni processuali derivanti da una violazione delle predette garanzie. Si esaminano, infine, le regole di apprezzamento della prova che guidano il giudice nella delicata fase valutativa.

Les TICE pour la production écrite et la traduction de l'italien vers le français : le cas de la SSLMIT de Forlì

Les recherches relatives à l'utilisation des TICE se concentrent fréquemment soit sur la dimension cognitive, sur la dimension linguistique ou sur la dimension culturelle. Le plus souvent, les recherches empiriques se proposent d'évaluer les effets directs des TICE sur les performances langagières des apprenants. En outre, les recherches, surtout en psychologie cognitive, sont le plus souvent effectuées en laboratoire. C'est pourquoi le travail présenté dans cette thèse se propose d'inscrire l'utilisation des TICE dans une perspective écologique, et de proposer une approche intégrée pour l'analyse des pratiques effectives aussi bien en didactique des langues qu'en didactique de la traduction. En ce qui concerne les aspects cognitifs, nous recourons à un concept apprécié des praticiens, celui de stratégies d'apprentissage. Les quatre premiers chapitres de la présente thèse sont consacrés à l'élaboration du cadre théorique dans lequel nous inscrivons notre recherche. Nous aborderons en premier lieu les aspects disciplinaires, et notamment l’interdisciplinarité de nos deux champs de référence. Ensuite nous traiterons les stratégies d'apprentissage et les stratégies de traduction. Dans un troisième mouvement, nous nous efforcerons de définir les deux compétences visées par notre recherche : la production écrite et la traduction. Dans un quatrième temps, nous nous intéresserons aux modifications introduites par les TICE dans les pratiques d'enseignement et d'apprentissage de ces deux compétences. Le cinquième chapitre a pour objet la présentation, l'analyse des données recueillies auprès de groupes d'enseignants et d'étudiants de la section de français de la SSLMIT. Il s’agira dans un premier temps, de présenter notre corpus. Ensuite nous procéderons à l’analyse des données. Enfin, nous présenterons, après une synthèse globale, des pistes didactiques et scientifiques à même de prolonger notre travail.

Untersuchungen zur Expression und Lokalisation der respiratorischen Proteine Neuroglobin (Ngb) und Cytoglobin (Cygb) in Säugern

Die vorliegende Dissertation beinhaltet Untersuchungen zur Expression und Funktion der respiratorischen Proteine Neuroglobin (Nbg) und Cytoglobin (Cygb) in Vertebraten. rnrnUm die Expression der Globine während der Entwicklung des Säugerhirns zu untersuchen, wurden die Hirne von Maus-Embryonen ab dem Fötalstadium MF10 bis zum Tag eins nach der Geburt (T1) mit Adulttieren verglichen. Quantifiziert wurde sowohl die mRNA- als auch die Protein-Expression. Beide Globine zeigten im Verlauf der Entwicklung einen stetigen Anstieg der mRNA-Expression, wobei Ngb zu Beginn in zehnfach höherer Konzentration vorlag und im zeitlichen Verlauf einen 130-fachen Anstieg zeigte. Cygb zeigte lediglich einen 16-fachen Anstieg bis zum Adultstadium. Auf Proteinebene konnte die Expressionszunahme beider Globine im Laufe der Entwicklung bestätigt werden. Weder in den hypoxieresistenten Frühembryonalstadien noch während der mit Sauerstoff-Stress verbundenen Geburt zeigte sich ein Expressionsmaximum. Dies spricht gegen eine Globin-Funktion in der Oxidanz-Abwehr. Eher ist zumindest Ngb mit der Reifung der Neurone und dem damit einhergehenden, gesteigerten oxidativen Stoffwechsel assoziiert.rnrnDes Weiteren sollte die zelluläre und intrazelluläre Lokalisation beider Globine anhand einer primären Zellkultur aus dem Hippocampus pränataler Ratten und in immortalen Zelllinien untersucht werden. Neuroglobin wurde dabei nur in Neuronen, nicht jedoch in Gliazellen nachgewiesen. Das Färbemuster war in allen Ngb-exprimierenden Zellen zytoplasmatisch. Cytoglobin wurde in der Primärkultur in den Neuronen jedoch ebenso in den mit anti-GFAP markierten Gliazellen beobachtet. In beiden Zellpopulationen war auch der Kern durch das CyGB-Antiserum markiert. rnEine genauere Untersuchung der intrazellulären Lokalisation sollte durch die Transfektion von Globin-pEGFP-Fusionsproteinen erfolgen. Nach Transfektion der Fusionskonstrukte wurde die GFP-Färbung bei beiden Globinen sowohl im Zytoplasma als auch im Kern beobachtet. Eine rein nukleäre Lokalisation, die insbesondere für Cygb von anderen Autoren postuliert wurde, konnte somit ausgeschlossen werden. rnrnIn primären Zellkulturen aus Cerebellum und Kortex, die mit Hilfe von Paraquat oxidativem Stress ausgesetzt wurden, wurde der Verlauf der Globin-mRNA-Expression mit dem unregulierten 18s rRNA-Referenzgen und mit den Antioxidanz-Enzymen Cu-Zn-SOD und Gpx verglichen. Neuroglobin zeigte einen Expressionsverlauf ähnlich dem der beiden Antioxidanz-Enzyme, jedoch liegt seine mRNA im Hirngewebe in hundertfach niedrigerer Menge als Cu-Zn-SOD und Gpx vor. Cytoglobin zeigte keine Veränderung der Expression. Eine Funktion der Globine im Sinne einer ROS-Abwehr kann aus den Befunden nicht abgeleitet werden. rnrnUntersuchungen von Tumor und Normalgewebe mittels eines cDNA-Cancer-Arrays zeigten, dass NGB in Tumoren verschiedenen Ursprungs nicht exprimiert wird, CyGB dagegen keine Änderung seiner Expression in Tumor versus Normalgewebe erfährt. Eine Induktion der beiden Globine z.B. durch Hypoxie in soliden Tumoren kann daher ausgeschlossen werden.rn

Reduction in Predator Defense in the Presence of Neighbors in a Colonial Fish

Predation pressure has long been considered a leading explanation of colonies, where close neighbors may reduce predation via dilution, alarming or group predator attacks. Attacking predators may be costly in terms of energy and survival, leading to the question of how neighbors contribute to predator deterrence in relationship to each other. Two hypotheses explaining the relative efforts made by neighbors are byproduct-mutualism, which occurs when breeders inadvertently attack predators by defending their nests, and reciprocity, which occurs when breeders deliberately exchange predator defense efforts with neighbors. Most studies investigating group nest defense have been performed with birds. However, colonial fish may constitute a more practical model system for an experimental approach because of the greater ability of researchers to manipulate their environment. We investigated in the colonial fish, Neolamprologus caudopunctatus, whether prospecting pairs preferred to breed near conspecifics or solitarily, and how breeders invested in anti-predator defense in relation to neighbors. In a simple choice test, prospecting pairs selected breeding sites close to neighbors versus a solitary site. Predators were then sequentially presented to the newly established test pairs, the previously established stimulus pairs or in between the two pairs. Test pairs attacked the predator eight times more frequently when they were presented on their non-neighbor side compared to between the two breeding sites, where stimulus pairs maintained high attack rates. Thus, by joining an established pair, test pairs were able to reduce their anti-predator efforts near neighbors, at no apparent cost to the stimulus pairs. These findings are unlikely to be explained by reciprocity or byproduct-mutualism. Our results instead suggest a commensal relationship in which new pairs exploit the high anti-predator efforts of established pairs, which invest similarly with or without neighbors. Further studies are needed to determine the scope of commensalism as an anti-predator strategy in colonial animals.

Effects of Ethylene on Secondary Xylem Formation in Arabidopsis thaliana

Ethylene has myriad roles as a plant hormone, ranging from senescence and defending against pathogen attacks to fruit ripening and interactions with other hormones. It has been shown to increase cambial activity in poplar, but the effect on wood formation in Arabidopsis hypocotyl has not previously been studied. The Auxin-Regulated Gene involved in Organ Size (ARGOS), which increases organ size by lengthening the time for cell division, was found to be upregulated by ethylene. We tested the effect of ethylene treatment at 10 and 100 µM ACC on three genotypes of Arabidopsis, Col0 (wild-type), an ARGOS deficient mutant (argos), and ein3-1, an ethylene insensitive mutant. ARGOS expression analysis with qPCR indicated that ACC does induce ARGOS and ARGOS-LIKE (ARL) in the hypocotyl. As seen in poplar, ethylene also decreases stem elongation.Histochemical staining, showed that ethylene changes the way secondary xylem lignifies, causing gaps in lignification around the outer edge of secondary xylem. Our results also implied that ethylene treatment changes the proportion of secondary to total xylem, resulting in less secondary, whereas in poplar, ethylene treatment caused an increase.

Induced Jasmonate Signaling Leads to Contrasting Effects on Root Damage and Herbivore Performance

Induced defenses play a key role in plant resistance against leaf feeders. However, very little is known about the signals that are involved in defending plants against root feeders and how they are influenced by abiotic factors. We investigated these aspects for the interaction between rice (Oryza sativa) and two root-feeding insects: the generalist cucumber beetle (Diabrotica balteata) and the more specialized rice water weevil (Lissorhoptrus oryzophilus). Rice plants responded to root attack by increasing the production of jasmonic acid (JA) and abscisic acid, whereas in contrast to in herbivore-attacked leaves, salicylic acid and ethylene levels remained unchanged. The JA response was decoupled from flooding and remained constant over different soil moisture levels. Exogenous application of methyl JA to the roots markedly decreased the performance of both root herbivores, whereas abscisic acid and the ethylene precursor 1-aminocyclopropane-1-carboxylic acid did not have any effect. JA-deficient antisense 13-lipoxygenase (asLOX) and mutant allene oxide cyclase hebiba plants lost more root biomass under attack from both root herbivores. Surprisingly, herbivore weight gain was decreased markedly in asLOX but not hebiba mutant plants, despite the higher root biomass removal. This effect was correlated with a herbivore-induced reduction of sucrose pools in asLOX roots. Taken together, our experiments show that jasmonates are induced signals that protect rice roots from herbivores under varying abiotic conditions and that boosting jasmonate responses can strongly enhance rice resistance against root pests. Furthermore, we show that a rice 13-lipoxygenase regulates root primary metabolites and specifically improves root herbivore growth.
