O processo de escolarização e a questão da identidade da criança da classe popular

o homem é simultaneamente um ser animal e um ser social. E não somente uma. síntese bio-pSico+rocial. mas tam bém ideológico-afetiva. .1 A formação da personalidade nO.rmal ?I~ patológica nao esti fundamentalmsnte centrada no indivídtioiiológico, mas sim em suas relaç5es com o mundo, isto é} no relaciona- mento de seu potencial bio-psíquico com o social. i ~ Entre to~o~ os animais é o homem aquele que possui relativamente ao período total de vida, a mais longa : infân cia e portanto o que atravessa o maior período de aprendiz~ ~. gem social. Nele, a educabilidade vem sobrepondo-se aos ins tintos. Na realidade, o homem inicia, ao nascer, um proce~ so de tomada de consciência mediatizado por sua relação com os objetos e as pessoas que o cercam, reconstruindo o mun do e elaborando gradativamente sua identidad~. I" I Nesse processo de conscientização ~~antitativa e qualitativa da realidade 6bjetiva e de si próprio, a escola ocupi um importante papel, não só como um lugar de transmis I são d~, conhecimento mas uma agência de socialização de gra~ de significado. Examinar teoricamente a importância desse processo de escolarização veiculado pela relação do professor com seu aluno, par:l a elaboração da idcntid:Hlc da criança da clas- se po~ular ê objetivo desse trabalho. A escola como processo de difusão de cultura influ '! encia na v1são de mundo que o aluno tem de si e dos outros, interferindo em certa medida nas suas próprias atitudes fren te a vida. A escola assume um significado mui to importante f~ cionando como ponte entre a identificação da família e o gru po social mais amplo. A discriminação econômica que sofre a criança da classe popular' ~ revivida na relação direta com seu profes- sor que valoriza a cultura da classe dominante, menospreza a, cultura popular. criando na criança pobre um sentimento de ihcapacidade que s6 serve para justificar a dominação. Na relação professor-aluno a criança revive seus cc:>nflitos sociais revestidos de seus conflitos familiares. Nesse sentido o exame da questão ideol6gica para o estudo da influência do processo de escolarização na forma- çao da identidade da criança da classe popular passa também por uma compreensão dos aspectos afetivos que estruturam a relação professor-aluno e que lhe servem de suporte.

O luto pela perda da saúde: vivências de ser mãe de uma criança com Fibrose Cística

Este estudo tem por objetivo compreender como as mães da criança com Fibrose Cística (FC) vivenciam o luto pela perda da saúde do seu filho, considerando que esta ocorrência representa uma ameaça de morte continua à vida da criança, quando da ausência da adesão do tratamento. A Fibrose Cística é uma doença crônica, genética, sem cura e potencialmente letal, com prognóstico reservado, que demanda tratamento de alto impacto e intenso cuidado. A estratégia metodológica fundamentou-se na abordagem clínico qualitativa, com ênfase na análise de conteúdo. Participaram deste estudo onze mães com filho diagnosticado com FC e que se encontrava em acompanhamento ambulatorial no Programa de Assistência de FC, do Hospital Universitário João de Barros Barreto. A coleta de dados foi realizada a partir de um encontro com a mãe para uma entrevista semiestruturada e a realização de dois desenhos com objetivo de compreender o luto destas mães em relação à doença FC de seu filho, suas perdas e significados em relação ao adoecimento da criança. Os resultados mostram que as mães vivenciam o luto pela perda da saúde da criança, desvelando os significados atribuídos a morte e o morrer, confirmado pela hipótese de que a mãe da criança com FC sabe sobre a doença, tem consciência da ameaça de morte e compreende que o tratamento pode proporcionar ao seu filho melhor qualidade de vida. Para elas a proximidade da existência de uma morte iminente traz uma reorganização e mudanças internas e externas, pessoais e familiares que favorecem a ressignificação suas vidas a partir do enfrentamento da doença.

Ocorrências e usos do Tucumã (astrocaryum vulgare mart) em comunidades ribeirinhas, quilombolas e de agricultores tradicionais no município de Irituia, Pará

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.

The Somatic Chromosomes of Some North American Marmots (Sciuridae), with Remarks on the Relationships of Marmota browerii Hall and Gilmore

Karyotypes are defined for two nearctic species of marmots, Marmota olympus (2n = 40) and M. vancouverensis (2n = 42), and supplemental information is included on the karyotypes of M. flaviventris, M. monax ochracea, and M. marmota. The six North American species of Marmota (NF = 66) comprise a distinct group as compared with the middle Asian species (NF = 70) for which the karyotypes are known. Karyologic findings and zoogeographic evidence based upon the distribution of two nearctic species of host-specific cestodes indicate that M. broweri, in northern Alaska, is a pre-Würm relict. Its affinities appear to be with the North American caligata-group rather than with the northeastern Siberian M. camtschatica. The occurrence on M. broweri of the Asian flea, Oropsylla silantiewi, has not been explained. Some ecological and behavioral characteristics of M. broweri are briefly described and compared with those of other species. Family groups of M. broweri hibernate together in single winter dens that are plugged at the entrance; copulation takes place before the animals emerge from the winter den, near mid-May; face-glands are utilized in marking of territory. French abstract: Les auteurs définissent les caryotypes de deux espèces néarctiques de marmottes, Marmota olympus (2n=40) et M. vancouverensis (2n=42), et donnent des précisions sur les caryotypes de M. flaviventris, M. monax ochracea et M. marmota. Les six especes de Marmota (NF=66) d'Amérique du Nord forment un groupe distinct des espèces d'Asie centrale (NF=70) dont Ie caryotype est connu. Les données caryologiques et les preuves zoogéographiques basées sur la répartition de deux espèces néarctiques de cestodes spécifiques de I'hôte démontrent que M. broweri, dans l'Alaska septentrional, est une relicte du pré-Würm. Elle semble avoir plus d'affinités avec Ie groupe nord américain de caligata qu'avec M. camtschatica du nord de la Sibérie. La présence sur M. broweri de la puce asiatique, Oropsylla silantiewi, n'est pas expliquée. Quelques caractéristiques écologiques et éthologiques de M. broweri sont décrites brièvement et comparées avec celles d'autres espèces. Les groupes familiaux de M. broweri hibernent dans un meme terrier dont l'entrée est bouchée; la copulation à lieu avant que les animaux sortent de leur abri hivernal, it la mi-mai ; ils se servent de leurs glandes faciales pour marquer leur territoire.

Das Burnout-Syndrom: eine medizinische Perspektive

The burnout syndrome is a heterogeneous concept mostly understood as a complex of symptoms, primarily exhaustion, in response to prolonged emotional and interpersonal stress at work. The prevalence of burnout is considerably high in Swiss primary care physicians. In spite of its vague definition, burnout is a serious stress disease with many associated medical problems and high economic costs. Previous recommendations for the psychosomatic management of patients with functional somatic syndromes also apply to burnout treatment. These are complemented by more specific interventions targeting job stress related factors. Relapse prevention focuses on early recognition of warning signs and is an ongoing process.

Empfehlungen zur Diagnostik und Therapie der behavioralen und psychologischen Symptome der Demenz (BPSD)

In patients with dementia, Behavioral and Psychological Symptoms of Dementia (BPSD) are frequent findings that accompany deficits caused by cognitive impairment and thus complicate diagnostics, therapy and care. BPSD are a burden both for affected individuals as well as care-givers, and represent a significant challenge for therapy of a patient population with high degree of multi-morbidity. The goal of this therapy-guideline issued by swiss professional associations is to present guidance regarding therapy of BPSD as attendant symptoms in dementia, based on evidence as well as clinical experience. Here it appears to be of particular importance to take into account professional experience, as at this point for most therapeutic options no sufficiently controlled clinical trials are available. A critical discussion of pharmaco-therapeutic intervention is necessary, as this patient-population is particularly vulnerable for medication side-effects. Finally, a particular emphasis is placed on incorporating and systematically reporting psycho-social and nursing options therapeutic intervention.

Übergangslösungen beim Eintritt in die Schweizer Berufsbildung: Brückenschlag oder Sackgasse?

In der Schweiz finden viele Jugendliche keinen direkten Zugang zu einer beruflichen Grundbildung; vielmehr durchlaufen sie zunächst eine so genannte Übergangslösung oder ein Brückenangebot wie z.B. ein zehntes Schuljahr. Wir beleuchten in diesem Beitrag zum einen, wie schulische, individuelle, familiäre und kontextuell-systemische Faktoren den Übertritt in solche Brückenangebote beeinflussen. Zum anderen gehen wir der Frage nach, wie sich ein verzögerter Einstieg via ein Brückenangebot auf die Chance auswirkt, einen Abschluss der Sekundarstufe II zu erwerben. Die empirische Analyse stützt sich auf die TREE-Studie, welche eine Kohorte von Schulentlassenen des Jahres 2000 längsschnittlich beobachtet. Wir modellieren dabei zunächst die interessierenden Übertrittsprozesse mittels einer multinomialen logistischen Regression, um dann mittels Propensity Score Matching deren Wirkung auf die nachobligatorischen Bildungschancen abzuschätzen.

Mutations in the nebulin gene associated with autosomal recessive nemaline myopathy

The congenital nemaline myopathies are rare hereditary muscle disorders characterized by the presence in the muscle fibers of nemaline bodies consisting of proteins derived from the Z disc and thin filament. In a single large Australian family with an autosomal dominant form of nemaline myopathy, the disease is caused by a mutation in the α-tropomyosin gene TPM3. The typical form of nemaline myopathy is inherited as an autosomal recessive trait, the locus of which we previously assigned to chromosome 2q21.2-q22. We show here that mutations in the nebulin gene located within this region are associated with the disease. The nebulin protein is a giant protein found in the thin filaments of striated muscle. A variety of nebulin isoforms are thought to contribute to the molecular diversity of Z discs. We have studied the 3′ end of the 20.8-kb cDNA encoding the Z disc part of the 800-kDa protein and describe six disease-associated mutations in patients from five families of different ethnic origins. In two families with consanguineous parents, the patients were homozygous for point mutations. In one family with nonconsanguineous parents, the affected siblings were compound heterozygotes for two different mutations, and in two further families with one detected mutation each, haplotypes are compatible with compound heterozygosity. Immunofluorescence studies with antibodies specific to the C-terminal region of nebulin indicate that the mutations may cause protein truncation possibly associated with loss of fiber-type diversity, which may be relevant to disease pathogenesis.

Reciprocal Prospective Associations Between Depressive Symptoms and Perceived Relationship With Parents in Early Adolescence

Objective: Adolescent depressive symptoms are associated with difficult family relationships. Family systems and interpersonal theories of depression suggest that this association could reflect a circular process in which symptoms and family functioning affect each other over time. Few longitudinal studies have tested this hypothesis, and the results of these studies have been equivocal. In this study, we examine reciprocal prospective associations in early adolescence between depressive symptoms and 2 important aspects of parent–child relationships: communication and conflict. Methods: Participants were 3862 students who annually filled out self-reports. Path analysis was used to examine prospective associations between depressive symptoms and perceived communication and conflict with parents from the age of 12 to 13 and 14 to 15 years. Independence of these associations was assessed by controlling for family context (parental separation and family socioeconomic status) and adolescent behaviour problems (delinquent behaviours and substance use). Sex differences were evaluated with multiple group analysis. Results: Reciprocal prospective associations were found between depressive symptoms and perceived conflict with parents, but not between depressive symptoms and communication with parents. Depressive symptoms were found to predict poorer communication with parents over time, but communication was not predictive of lower depressive symptoms in subsequent years. All paths were sex-invariant and independent from family context and behaviour problems. Conclusion: This study highlights the importance of considering the potential impact of adolescent symptomatology on parent–child relationships and suggests that reciprocity may characterize the association between depressive symptoms and negative aspects of parent–child relationships. The role of adolescent perceptions in the interplay between depressive symptoms and family relationships remains to be clarified.

Les mécanismes sous-jacents aux effets pathologiques cardiaques de l’angiotensine II dans le remodelage électrique et contractile entre les sexes

L’insuffisance cardiaque (IC) est associée à un taux de mortalité et d’hospitalisations élevé causant un fardeau économique important. Les deux causes majeures de décès de l’IC sont les arythmies ventriculaires létales et les sidérations myocardiques. Il est maintenant reconnu que l’angiotensine II (ANGII) est l'un des principaux médiateurs de l’IC. Ses effets délétères découlent de l’activation du récepteur de type 1 de l’ANGII (AT1) et entraînent le développement d’hypertrophie. Toutefois, son rôle dans la genèse d’arythmies demeure incompris. De ce fait, l'étude des mécanismes électriques et contractiles sous-jacents aux effets pathologiques de l’ANGII s’avère essentielle afin de mieux comprendre et soigner cette pathologie. Il est souvent perçu que les femmes sont protégées envers les maladies cardiovasculaires. Cependant, le nombre total de femmes décédant d’IC est plus grand que le nombre d’hommes. Également, l’impact des facteurs de risque diffère entre chaque sexe. Ces différences existent, mais les mécanismes sous-jacents sont encore peu connus. De plus, les femmes reçoivent fréquemment un diagnostic ou un traitement inapproprié en raison d’un manque d’information sur les différences entre les sexes dans la manifestation d’une pathologie. Ce manque de données peut découler du fait que les sujets de sexe féminin sont souvent sous-représentés dans les essais cliniques ou la recherche fondamentale ce qui a grandement limité l’avancement de nos connaissances sur ~50 % de la population. Ainsi, il semble plus que nécessaire d’approfondir notre compréhension des différences entre les sexes, notamment dans la progression de l’IC. L’utilisation d’un modèle de souris transgénique surexprimant le récepteur AT1 (souris AT1R) a permis d’étudier les changements électriques, structurels et contractiles avant et après le développement d’hypertrophie. Premièrement, chez les souris AT1R mâles, un ralentissement de la conduction ventriculaire a été observé indépendamment de l’hypertrophie. Ce résultat était expliqué par une réduction de la densité du courant Na+, mais pas de l’expression du canal. Ensuite, le rôle des protéines kinases C (PKC) dans la régulation du canal Na+ par l’ANGII a été exploré. Les évidences ont suggéré que la PKCα était responsable de la modulation de la diminution du courant Na+ chez les souris AT1R mâles et dans les cardiomyocytes humains dérivés de cellules souches induites pluripotentes (hiPSC-CM) en réponse à un traitement chronique à l’ANGII. Ensuite, les différences entre les sexes ont été comparées chez la souris AT1R. Une plus grande mortalité a été constatée chez les femelles AT1R suggérant qu’elles sont plus sensibles à la surexpression de AT1R. Le remodelage électrique ventriculaire a donc été comparé entre les souris AT1R des deux sexes. Les courants ioniques étaient altérés de façon similaire entre les sexes excluant ainsi leur implication dans la mortalité plus élevée chez les femelles. Ensuite, l’homéostasie calcique et la fonction cardiaque ont été étudiées. Il a été démontré que les femelles développaient une hypertrophie et une dilatation ventriculaire plus sévère que les mâles. De plus, les femelles AT1R avaient de petits transitoires calciques, une extrusion du Ca2+ plus lente ainsi qu’une augmentation de la fréquence des étincelles Ca2+ pouvant participer à des troubles contractiles et à la venue de post-dépolarisations précoces. En conclusion, l’ANGII est impliquée dans le remodelage électrique, structurel et calcique associé à l'émergence de l’IC. De surcroît, ces altérations affectent plus sévèrement les femelles soulignant la présence de différences entre les sexes dans le développement de l’IC.
