La relaci??n teor??a-pr??ctica en la ense??anza y el desarrollo profesional docente : un estudio de caso en Primaria

En el ??mbito de la educaci??n se plantea que es necesario establecer relaciones entre la teor??a y la pr??ctica, haciendo converger el conocimiento did??ctico y la acci??n docente, pero apenas se ha investigado sistem??ticamente sobre ello. En esta tesis se abordan estas relaciones mediante un estudio de caso ??nico en Educaci??n Primaria, siguiendo una metodolog??a etnogr??fica, para analizar las implicaciones de las mismas en la ense??anza y el desarrollo profesional docente. Esta investigaci??n trata de elaborar un marco te??rico amplio que permita situar el tema de las relaciones entre la teor??a y la pr??ctica en la ense??anza realizando un estado de la cuesti??n, as?? como fundamentando el marco metodol??gico seguido. El trabajo emp??rico, se centra en un aula de Educaci??n Primaria en la que trabaja un maestro que ha dedicado m??s de treinta a??os de su vida profesional al estudio de las relaciones teor??a-pr??ctica, elaborando abundantes documentos y publicaciones al respecto, as?? como innovadoras formas de ense??ar a lo largo de su ejercicio profesional, promoviendo el establecimiento de relaciones entre el conocimiento acad??mico educativo y la pr??ctica escolar. La investigaci??n se enmarca en el aula objeto de observaci??n, pero, a su vez, transciende este marco, incorporando a la investigaci??n a diversidad de personas vinculadas a la comunidad escolar del centro siguiendo pautas de trabajo de orden cualitativo: observaci??n participante, entrevistas, foros de discusi??n y an??lisis de documentos, fundamentalmente. En el estudio se concluye que la relaci??n teor??a-pr??ctica debe favorecerla el profesorado en su ejercicio docente, favoreciendo la cooperaci??n entre la instituci??n acad??mica universitaria y los centros escolares, en la medida de sus posibilidades.

Ethnic Identity in an Intercultural Geography: an Empirical Study = L’identité ethnique dans une géographie interculturelle: une étude empirique

This study explored the ethnic identity among 331 emerging adults (144 mestizos and 187 indigenous) from the Intercultural University of Chiapas (México). Scholars suggest that ethnicity is much more salient for ethnic minority adolescents than for adolescents who are members of the ethnic majority. Our aim was to compare the results of the Multigroup Ethnic Identity Measure (MEIM) between the majority ethnic group and the minority group studied. Specifically, the following hypothesis was examined: adolescents who are members of the ethnic minority group (indigenous) will score significantly higher on ethnic identity than adolescents who are members of the ethnic majority group (mestizos). The results supported these hypothesis. We suggest that the effect of an intercultural educative model could explain these results

Bioinspired iron and manganese catalysts for the effective and selective oxidation of alkanes and alkenes

La gran eficiència, selectivitat i les condicions suaus exhibides per les reaccions que tenen lloc al centre actiu de les metal·looxigenases són la font d'inspiració per la present dissertació. Amb l'objectiu de dissenyar catalitzadors d'oxidació eficients hem fet ús de dues estratègies: la primera consisteix en el disseny de complexos amb baix pes molecular inspirats en aspectes estructurals de la primera esfera de coordinació del centre metàl·lic d'enzims de ferro i de manganès. Aquests complexos s'han estudiat com a catalitzadors en l'oxidació selectiva d'alcans i d'alquens fent servir oxidants "verds" com ara l'H2O2. La segona estratègia està basada en l'ús de la química supramolecular per tal de desenvolupar estructures moleculars auto-acoblades amb la forma i les propietats químiques desitjades. Concretament, la construcció de nanocontenidors amb un catalitzador d'oxidació incrustat a la seva estructura ens permetria dur a terme reaccions més selectives, tal com passa en les reaccions catalitzades per enzims.

Discoespondilite Canina : Estudo Retrospectivo de 10 Casos Clínicos

A discoespondilite é uma doença infecciosa rara que afecta, de forma crónica, os discos intervertebrais e as extremidades adjacentes dos corpos vertebrais. Geralmente advém de uma infecção disseminada por via hematógena e os agentes mais frequentes são bacterianos e são principalmente Staphylococcus spp., Streptococcus spp., E. Coli e Brucella spp. Também pode ser devida a infecções fúngicas, parasitárias ou migração de corpos estranhos. É caracterizada pela degenerescência do disco intervertebral e lesões escleróticas e proliferativas das extremidades dos corpos vertebrais. O principal sinal clínico desta doença é a hiperestesia paravertebral e alterações da marcha ou relutância ao movimento. Febre e anorexia são menos frequentes do que seria de esperar e os sinais neurológicos são considerados raros. O diagnóstico desta doença é geralmente radiográfico e a determinação do agente pode ser conseguida por cultura de material discal, hemocultura ou urocultura. Podem ser usados meios de imagiologia avançada como TAC e RM para melhor avaliar a extensão das lesões e o envolvimento dos tecidos circunvizinhos. A realização de hemogramas raramente revela alterações significativas embora possa existir leucocitose. O tratamento médico é eficaz em aproximadamente 76% dos casos e deve ser feito com base em cultura e TSA mas, de forma empírica, as cefalosporinas de primeira geração são frequentemente utilizadas. Em alguns casos pode ser necessária a estabilização ou desbridamento cirúrgicos. O estudo retrospectivo realizado no âmbito deste trabalho, teve como objectivo avaliar os sinais clínicos, radiográficos e laboratoriais , assim como o maneio médico e cirúrgico de 10 casos de discoespondilite confirmada radiográfica e clinicamente, num período de 2 anos. Observou-se maior prevalência da doença em machos, em cães jovens e adultos, e raças de grande porte. A região mais afectada foi a junção lombossagrada, e o sinal mais observado foi a dor paraespinhal. No entanto os sinais neurológicos foram mais frequentes do que o descrito. Os agentes isolados em cultura de material discal não foram os mais comuns. O tratamento médico instituído pelos veterinários foi eficaz em 6 dos casos, Foi necessária intervenção cirúrgica em 3 e 1 animal não recuperou totalmente até à conclusão deste estudo.

Teachers’ voices about being a teacher: comparative studies in England, Finland and Sweden

The aim of the article is to present and discuss a study in which Finnish, English and Swedish teachers and student teachers described the implications of being a teacher. It is cross-national and consists of multiple case studies. Data were collected through twenty-four focus group dialogues, and 110 teachers/student teachers participated in the study. According to the study, we have found that teachers and student teachers in all three countries promoted pupils’ development of critical thinking, which is another way of saying that they focused on ‘the attitudes and values’ aspect of citizenship education; however, this was most evident in the Finnish and the Swedish focus groups. In England there is a subject emphasis to the professional role, the three countries ranked the topics (the pupils; the subject; the organization; the society; teacher identity; parents) equally, in Finland the teacher role did not appear to be as post modern as in the two other countries.

Growth and public infrastructure

The paper analyzes a multicountry extension of the Barro model of productive public expenditure. In the presence of positive infrastructural externalities between countries, the provision of infrastructure will be inefficiently low if countries do not coordinate. This provides a role for a supranational body, such as the European Union, to coordinate the policies of the individual governments. It is shown how intervention by a supranational body can raise welfare by internalizing the infrastructural externality. Infrastructural externalities increase the importance of tax policy in the growth process and distribute the benefits of taxation across countries.

Perspex machine X: software development

The Perspex Machine arose from the unification of computation with geometry. We now report significant redevelopment of both a partial C compiler that generates perspex programs and of a Graphical User Interface (GUI). The compiler is constructed with standard compiler-generator tools and produces both an explicit parse tree for C and an Abstract Syntax Tree (AST) that is better suited to code generation. The GUI uses a hash table and a simpler software architecture to achieve an order of magnitude speed up in processing and, consequently, an order of magnitude increase in the number of perspexes that can be manipulated in real time (now 6,000). Two perspex-machine simulators are provided, one using trans-floating-point arithmetic and the other using transrational arithmetic. All of the software described here is available on the world wide web. The compiler generates code in the neural model of the perspex. At each branch point it uses a jumper to return control to the main fibre. This has the effect of pruning out an exponentially increasing number of branching fibres, thereby greatly increasing the efficiency of perspex programs as measured by the number of neurons required to implement an algorithm. The jumpers are placed at unit distance from the main fibre and form a geometrical structure analogous to a myelin sheath in a biological neuron. Both the perspex jumper-sheath and the biological myelin-sheath share the computational function of preventing cross-over of signals to neurons that lie close to an axon. This is an example of convergence driven by similar geometrical and computational constraints in perspex and biological neurons.

Advanced skills teachers: professional identity and status

The teaching profession continues to struggle with defining itself in relation to other professions. Even though public opinion positions teachers second only to doctors and nurses in terms of their professional status and prestige research in the UK suggests that teachers still believe that they have much lower status than other professions. With teacher job satisfaction considerably lower today than the past and on-going issues with teacher recruitment and retention, new government policies have set out to enhance the status of teachers both within and outside of the profession. The Advanced Skill Teacher (AST) grade was introduced in 1998 as a means to recognise and reward teaching expertise and was framed as a way of also raising the status of the teaching profession. As to what a teaching professional should look like, the AST was in many ways positioned as the embodiment. Using survey data from 849 ASTs and in depth interviews with 31, this paper seeks to explores the ways that the AST designation impacts or not on teachers’ perceptions of their professional identity. In particular, the paper considers whether such awards contribute in positive ways to a teacher’s sense of professional identity and status. The results from the research suggest that teaching grades that recognise and reward teaching excellence do contribute in important ways to a teachers’ professional identity via an increased sense of recognition, reward and job satisfaction. The results from this research also suggest that recognising the skills and expertise of teachers is clearly important in supporting teacher retention. This is because as it allows highly accomplished teachers to remain where they want to be and that is the classroom.

Molecular detection of enterotoxins in environmental strains of Aeromonas hydrophila and Aeromonas jandaei

Aeromonas species are widely distributed in aquatic environments and recent studies include the genus in the emergent pathogens group because of its frequent association with local and systemic infections in immunocompetent humans. Aiming to search for virulence genes in environmental strains of Aeromonas hydrophila and Aeromonas jandaei, we designed specific primers to detect act/hly A/aer complex and alt genes. Primers described elsewhere were used to detect ast. Eighty-seven strains previously identified using phenotypic and genotypic tests as A. hydrophila (41) and A. jandaei (46) were analysed for the presence of the virulence genes using PCR. DNA fragments of expected size were purified and directly sequenced. Among the 41 strains of A. hydrophila 70.7% (29), 97.6% (40) and 26.8% (11) possessed act/hly A/aer complex, ast and alt genes, respectively. Among the 46 strains of A. jandaei, 4.4% (2), 0% (0) and 32.6% (15) were positive for act/hly A/aer complex, ast and alt genes, respectively. Sequencing allowed for the confirmation of amplified products using BLAST. The present work proposes a specific and rapid diagnostic method to detect the main virulence determinants of Aeromonas, a genus potentially pathogenic to humans.
