Relatório da prática de ensino supervisionada na Escola Básica 2, 3/S Cunha Rivara, Arraiolos

O presente relatório tem como objetivo a explanação e a discussão de forma concisa da atividade docente desenvolvida no ano letivo 2012/2013, na Escola Básica 2,3/S Cunha Rivara de Arraiolos com as turmas do 8.º C e 11.º D nas disciplinas de Ciências Naturais e Saúde respetivamente, sob a orientação da Doutora Marília Cid. Apresentam-se os fundamentos teóricos que sustentaram o delineamento de todas as metodologias e estratégias de ensino no sentido de promover situações de aprendizagem significativa aos alunos das turmas referidas. Este é também um testemunho da participação ativa no projeto de educação para a saúde em colaboração com as entidades promotoras de saúde no Concelho de Arraiolos no sentido de organizar atividades extracurriculares propiciadoras da aprendizagem nesta dimensão, com a dinamização de sessões de esclarecimento de Educação Sexual a várias turmas da escola e a produção de um website informativo e de apoio aos alunos do 3.º Ciclo do Ensino Básico e do Ensino Secundário sobre Educação Sexual. Foi apanágio deste trabalho a análise e reflexão também evidenciadas no trabalho de investigação sobre as atividades desenvolvidas no âmbito da Educação para a Saúde mas também em toda a atividade de lecionação. Esta análise e reflexão, bem como a pesquisa individual e o trabalho colaborativo permitiram o desenvolvimento progressivo das minhas capacidades, da qualidade do trabalho desenvolvido e o melhoramento da formação académica. /ABSTRACT: This report aims at explaining concisely and discussion of teaching developed in the academic year 2012/2013, at Escola Básica 2,3 / S Cunha Rivara in Arraiolos with classes C from 8th grade class and D from 11th , in the disciplines of Natural Sciences and Health respectively under the guidance of PhD Teacher Marilia Cid. Here we present the theoretical foundations that supported the design of all methodologies and teaching strategies to promote meaningful learning situations for students of classes above. This is also a testament to the active participation in the design of health education in collaboration with the health promoters in the County of Arraiolos to organize extracurricular activities conducive learning these dimensions, the organization of information sessions to various Sex Education school classes and the production of an informational website to support the students of the 3rd cycle and Secondary Education on Sexual Education. It was the hallmark of this work, analysis and reflection evidenced in research work on the activities within the Health Education but also of the entire teaching activity. This analysis and reflection as well as individual research and collaborative work allowed the progressive development of my abilities, quality of work and the improvement of academic training.

Média-arte locativa e mapeamentos dinâmicos na compreensão de fluxos urbanos : o contributo do dispositivo móvel na atividade do caminhar como prática artística

O interesse pela análise de espaços urbanos através de dispositivos comunicacionais móveis (de meios digitais) – perspetivando a sua transformação contando com a participação colaborativa da população – traduz o enquadramento geral da investigação. As práticas artísticas, complementadas por métodos de estudo de cidades (capazes de abordarem a respetiva complexidade de modo multioperativo e flexível), foram integradas na pesquisa tendo em linha de conta o acentuado desenvolvimento que as mesmas têm conhecido para a compreensão da atual condição urbana. O resultado foca a hibridização de processos que permitem acrescentar conhecimento coletivo sobre estruturas urbanas, expresso em mapeamentos dinâmicos que promovem leituras aumentadas de realidades urbanas. Assente no enquadramento teórico e respetiva revisão da literatura (abrangendo áreas disciplinares da média-arte locativa, da análise urbana e dos mapeamentos dinâmicos), procedeu-se ao desenvolvimento de dois artefactos complementares, cuja elaboração implicou três fases: i) pré-produção; ii) produção; iii) pós-produção. Na primeira, conceptualizaram-se os artefactos, definindo-se critérios e especificando parâmetros de análise. Complementarmente, consideraram-se softwares a utilizar bem como a seleção de atores urbanos que participaram em experiências associadas à investigação. No que se refere à produção, encetaram-se diversas ações de apropriação e apreensão de espaços urbanos selecionados na Vila de Caminha, recorrendo à técnica do caminhar mediado pela tecnologia. Na terceira fase, a informação resultante foi analisada, comparada e sistematizada através de uma reflexão final. Registaram-se marcas e apropriações na Vila de Caminha, integrando abordagens da média-arte locativa, da morfologia urbana e tecnologias digitais. A partir desta metodologia, a resposta aos objetivos da investigação contribui para a colmatação da lacuna identificada no estado arte, dado demonstrar-se a relevância da convergência operativa entre a apreensão urbana e os fluxos informacionais e comunicacionais para o revelar de vivências espaciais urbanas quotidianas (passadas e presentes) que ocorrem sobre a estrutura física das cidades. Em síntese, as práticas artísticas, provindas da média-arte locativa, expressam – em mapeamentos dinâmicos e através de realidade aumentada – o devir coletivo de experiências individuais nos espaços das cidades, acrescentando histórias à sua memória e história urbana.

De gata borralheira a Cinderela :nova espacialidade decorrente do desenvolvimento turístico, diferenciada pelo estilo de vida em Ponta Negra, Natal, RN

The transformations economical, social and politics in you finish them decades of the century XX brought changes that didn't just limit to the production system. The flexible accumulation took many workers lost her/it their workstations and they look for her/it new survival forms, migrating for administrative activities, of services rendered and for the tourist activity of small and medium load. The State has been investing in the implantation of plans of tourist development in order to create favorable conditions for the reproduction of the tourist activity in Brazil, mainly in the Northeast. A space when it starts to present a predominant economical activity suffers a restructuring in their social and economical relationships. The restructuring of these relationships takes to the construction of a new espacialidade. In the city of Christmas, in Rio Grande do Norte, the neighborhood of Black Tip is the most representative of the public investments for the tourist development. After intense process of tourist urbanization, Black Tip passed interfering in the global context consolidating as the tourist locus in the city. The tourist urbanization of the neighborhood took to the transformation of the space in merchandise that is sold and consumed as such. The recreation of fragments of other cultures brought by social actors, resulting from migratory processes stimulated by the tourist development, it has been presenting ruled social relationships in the informational technology, consumption of global goods and in the fragmentation of the urban space characterized by the internationalization and cosmopolitização. That process has been masking the inequalities partners and cultural as well as the territorial appropriation for an economical elite. The spaces are being appropriate for investors of the tourist section, private investors, agents and real estate producers, where the inequality is not just economical, but also cultural. The local population, mainly of the urban fraction of the Town of Black Tip, it doesn't participate of the productive process in function of the little or any professional qualification and he/she doesn't also have access to the consumption process. To the native ones it remains the fight for the preservation of his/her cultural identity and for the survival

Interface cena e tecnologia : composições cênicas mediadas

Based on the presupposition that the arts in the West always counted on resources, supports, and devices pertaining to its time context, an reflection is intended regarding the scenic compositions mediated by digital technologies do. Such technologies are inserted in the daily routine, also composing artistic experiments, thus playing a dialogical role with the art/technology intersection. Therefore, the proposal is to investigate what relationships are established in the contemporary theatrical scene from the contagion by digital technologies, aiming at establishing this parallel through a dialogue with the authors discussing the subject, and also based on the group practices having technological resources as a determinant factor in their plays. Furthermore, a reflection should be made on the scene that incorporates or is carried out in intermediatic events, analyzing how digital technologies (re)configure compositional processes of the plays by GAG Phila7, in the city of São Paulo/SP. For such, the dissertation is organized in three sections comprising four moments, to wit: brief overview of the field, contextualization, poetic analysis and synthesis. Qualitative methods are used as the methodological proposal: semi-structure interview, note and document taking (program, website, playing book, disclosure material for advertising text, photographs, and videos). Within the universe of qualitative research, it works with the epistemological perspective of the Gadamer philosophical hermeneutics. The possibilities allowed by the double virtual (Internet/web) generated a type of theater with another material basis and new forms of organization and structure, being possible to perceive that such technological advances and the arts are mutually contaminated, generating a dislocation in the logics of theatrical composition, movement beginning with the artistic vanguards, gradually intensified, thus offering new possibilities of constructions and hybridization of the of the most different possible types. Experiment ―Profanações_superfície de eventos de construção coletiva‖, idealized by Phila7 is inserted in this perspective. Object of the discussion of such research, the experiment works with possible poetics arising from the intersection with the digital technologies, aiming at identifying and problematizing the challenges from the technological evolution and expansion in a scenic context

My school, my market

Australia’s Education Revolution, launched in 2008, emphasised equity as a key reason for reforms. It identified ‘pockets of disadvantage’ as one of the main problems that needed to be addressed through its reforms. Through a series of translations, the problem of ‘pockets of disadvantage’ was converted to one of a lack of information, a lack of comparable metrics and the absence of an informed public, leading to a number of solutions such as the development of a national assessment scheme and the My School website. In this paper, using the theoretical and methodological resources of actor-network theory, I argue that these translations were also, simultaneously, the processes by which the Australian education space was further ‘marketised’. These marketisation processes involved homogenisation, whereby schools were rendered comparable through the development of common evaluation and common metrics; the development of informational resources that enabled parents to function as economic agents and exert ‘market forces’; and coordinating the activities of the actors through the My School website. The paper concludes with a discussion of how such descriptive analyses might serve as critique.

Inclusion, organisational justice and employee well-being

Purpose: The purpose of this paper is to examine the relationship between employee perceived well-being and the four dimensions of organisational justice, namely, procedural, distributive, interpersonal and informational justice, and how dimensions of organisational justice affect employee well-being in the Australian tourism industry. Design/methodology/approach: The sample is selected from employees who work in the tourism industry in Australia, and the survey was conducted online (n=121). Factor analysis is used to identify key items related to perceived organisational justice, followed by multiple regression analysis to assess the magnitude and strength of impacts of different dimensions of organisational justice on employee well-being. Findings: The results support the established view that organisational justice is associated with employee well-being. Specifically, informational justice has the strongest influence on tourism employee well-being, followed by procedural justice, interpersonal justice and distributive justice. Research limitations/implications: The authors acknowledge key limitations in the study such as a relatively small sample size and gender imbalance in the sample. Practical implications: The authors provide strategies for managers to increase levels of organisational justice in the tourism sector such as workgroup interactions, a consultation process, team culture and social support. Originality/value: This study builds on limited literature in the area of inclusion and organisational justice in tourism organisations. The study provides a new path to effective organisational management within the context of a diverse workforce, adding to the current debate on which dimensions of organisational justice contribute to improving employee well-being.

Perceptions of mobile plan unit pricing and terms and conditions

Purpose: The purpose of this paper is to test the efficacy of disclosing unit pricing and increasing the type size of complex terms and conditions in advertising. This is in line with recommendations made by global telecommunications regulators, including in Australia, to protect consumers in selecting mobile plans.

Design/methodology/approach: The authors employed a 2 (unit price disclosed: no, yes)×3 (type size: nine-, 12- and 15-point terms and conditions) full factorial, between-subjects experimental design using a scenario and fictional advertisements for 24-month mobile phone plans. This was complemented by 24 in-depth interviews with consumers who had recently purchased “real” plans and their assessment of these.

Findings: Extra information in the form of unit pricing has a positive influence on consumers’ value perceptions, but not on perceived confusion or risk. Presenting complex terms and conditions in larger type increases consumers’ perceived confusion and risk, but not perceived value, as consumers have difficulty understanding the complicated information presented.

Research limitations/implications: This study focused on a single country market for one product type of mobile phones, using a limited range of mobile plans. Practical implications: Public policymakers and providers are advised to pre-test planned changes to advertising’s informational content prior to implementation to identify the efficacy of proposed changes to protect consumers. Consumers may also need to be educated to accurately interpret complex plans.

Originality/value: The study contributes to the domain of informational content in advertising as a form of consumer protection. The effect of unit pricing and larger type for terms and conditions on consumer perceptions has not been examined previously in complex product settings.
