O presente trabalho analisa o papel de uma abordagem plural de sensibilização à diversidade linguística na promoção da consciência fonológica de crianças em idade pré-escolar. Para o efeito, acompanha o percurso de desenvolvimento da consciência fonológica de um grupo de vinte e uma crianças, com idades compreendidas entre os 3 e os 6 anos, que participaram num projeto de sensibilização à diversidade linguística, intitulado «Uma viagem pelo mundo das línguas e dos sons». Abraçando um paradigma misto de investigação, o estudo recorreu a procedimentos quantitativos e qualitativos de recolha e análise de dados: com o objetivo de avaliar o desenvolvimento fonológico das crianças, recolheram-se e analisaram-se estatisticamente dados provenientes de testes de consciência fonológica, que foram aplicados a um grupo experimental e a um grupo de controlo, antes e após a realização do projeto de intervenção; de forma a compreender como se processou o desenvolvimento da consciência fonológica das crianças, foram feitos registos áudio e vídeo das sete sessões do projeto que foram, posteriormente, transcritos e submetidos a uma análise de conteúdo. Os resultados da análise revelam que, ao contrário das crianças do grupo de controlo, as crianças que participaram no projeto de intervenção desenvolveram a sua consciência fonológica de forma significativa, sobretudo no que se refere às capacidades de manipulação e segmentação fonémicas. Esse desenvolvimento foi mais visível em crianças mais velhas (5-6 anos) do que em crianças mais novas (3-4 anos) e parece ter sido promovido pelas atividades de sensibilização à diversidade linguística em que as crianças participaram. Em particular, as atividades de análise e de comparação inter e intralinguística despertaram a curiosidade das crianças em relação ao objeto-língua e estimularam uma vontade para brincar com os sons e com as letras, o que possibilitou o desenvolvimento de uma consciência mais explícita das unidades do oral e a descoberta do princípio alfabético. Estes resultados atestam a importância da integração curricular de abordagens plurais na educação da infância, no âmbito de uma educação global e integrada, capaz de atender às diversidades das crianças, promover atitudes positivas face à alteridade e assegurar o desenvolvimento de competências metalinguísticas, indispensáveis para uma aprendizagem ao longo da vida e para uma participação ativa em sociedades multilingues e multiculturais.

With the aim to provide new insights into operational cetacean-fishery interactions in Atlantic waters, this thesis assesses interactions of cetaceans with Spanish and Portuguese fishing vessels operating in Iberian and South West Atlantic waters. Different opportunistic research methodologies were applied, including an interview survey with fishers (mainly skippers) and onboard observations by fisheries observers and skippers, to describe different types of interactions and to identify potential hotspots for cetacean-fishery interactions and the cetacean species most involved, and to quantify the extent and the consequences of these interactions in terms of benefits and costs for cetaceans and fisheries. In addition, the suitability of different mitigation strategies was evaluated and discussed. The results of this work indicate that cetaceans interact frequently with Spanish and Portuguese fishing vessels, sometimes in a beneficial way (e.g. cetaceans indicate fish schools in purse seine fisheries), but mostly with negative consequences (depredation on catch, gear damage and cetacean bycatch). Significant economic loss and high bycatch rates are, however, only reported for certain fisheries and associated with particular cetacean species. In Galician fisheries, substantial economic loss was reported as a result of bottlenose dolphins damaging artisanal coastal gillnets, while high catch loss may arise from common dolphins scattering fish in purse seine fisheries. High cetacean bycatch mortality arises in trawl fisheries, mainly of common dolphin and particularly during trawling in water depths below 350 m, and in coastal set gillnet fisheries (mainly common and bottlenose dolphins). In large-scale bottom-set longline fisheries in South West Atlantic waters, sperm whales may significantly reduce catch rates through depredation on catch. The high diversity of cetacean-fishery interactions observed in the study area indicates that case-specific management strategies are needed to reduce negative impacts on fisheries and cetaceans. Acoustic deterrent devices (pingers) may be used to prevent small cetaceans from approaching and getting entangled in purse seines and set gillnets, although possible problems include cetacean habituation to the pinger sounds, as well as negative side effects on non-target cetaceans (habitat exclusion) and fisheries target species (reduced catch rates). For sardine and horse mackerel, target species of Iberian Atlantic fisheries, no aversive reaction to pinger sounds was detected during tank experiments conducted in the scope of this thesis. Bycatch in trawls may be reduced by the implementation of time/area restrictions of fishing activity. In addition, the avoidance of fishing areas with high cetacean abundance combined with the minimization of fishery-specific sound cues that possibly attract cetaceans, may also help to decrease interactions. In large-scale bottom-set longline fisheries, cetacean depredation on catch may be reduced by covering hooked fish with net sleeves ("umbrellas") provided that catch rates are not negatively affected by this gear modification. Trap fishing, as an alternative fishing method to bottom-set gillnetting and longlining, also has the potential to reduce cetacean bycatch and depredation, given that fish catch rates are similar to the rates obtained by bottom-set gillnets and longlines, whereas cetacean by-catch is unlikely. Economic incentives, such as the eco-certification of dolphin-safe fishing methods, should be promoted in order to create an additional source of income for fishers negatively affected by interactions with cetaceans, which, in turn, may also increase fishers’ willingness to accept and adopt mitigation measures. Although the opportunistic sampling methods applied in this work have certain restrictions concerning their reliability and precision, the results are consistent with previous studies in the same area. Moreover, they allow for the active participation of fishers that can provide important complementary ecological and technical knowledge required for cetacean management and conservation.

The aim of this quasi-experimental research study was to investigate whether guided small-group discussions that involved explaining, analysing or justifying design and followed a modeling session from the teacher could improve students' creativity in web design. The convenience sample comprised of 37 third year students of the ""Publication Design and Hypermedi Technology"" program at John Abbott College in Sainte-Anne-de-Bellvue, Quebec who had enrolled in the Web Design course offered in the Fall semester of 2011. The primary instrument of this study was a set of two assigments for the course. A traditional teaching method was used during the first assignment and a small-group teaching strategy was implemented during the second one. Another instrument used in this research was a questionnaire on willingness to participate in teamwork. The last instrument of this study was a questionnaire on the type of intelligences that students possessed. It is hoped that the knowledge gathered from the study will add to the information about group-work activities and critiquing in particular.

Die nachfolgend berichteten Ergebnisse basieren auf einem vignettenbasierten 2x2-Szenario-Experiment, in das die Situationsfaktoren Entdeckungswahrscheinlichkeit und Vorteilswert sowie die Personenfaktoren Organisationaler Zynismus, das Fünf-Faktoren-Modell der Persönlichkeit und Intelligenz einbezogen wurden. In diesem Bericht werden vorrangig die Ergebnisse zur Persönlichkeitsdimension Gewissenhaftigkeit vorgestellt, einem der Faktoren des Fünf-Faktoren-Modells der Persönlichkeit. Diese Ergebnisse werden ausführlich berichtet, weil sie von besonderer Bedeutung für das vom TÜV Hannover/Sachsen-Anhalt e.V. finanzierte Forschungsprojekt Korruption – Risikofaktoren der Person und der Situation (Laufzeit 2011 bis 2015) sind. Die nachfolgend berichtete Untersuchung zeigt, dass ein akteurszentrierter Ansatz in der Korruptionsursachenforschung grundsätzlich sinnvoll ist. Es wurden 113 Auszubildende in den Bereichen Banken- und Versicherungen sowie Sozialversicherung befragt. Die Ergebnisse zeigen, dass Korruption als verbreitete Verhaltensweise angesehen wird, die jedoch als verwerflich gilt. Während die einbezogenen Situationsfaktoren keine nennenswerten Effekte auf die Korruptionsbereitschaft hatten, führten einige der Personenfaktoren zu signifikanten Ergebnissen. Gewissenhaftigkeit kommt hierbei als Schutzfaktor vor korrupten Handlungen besondere Bedeutung zu.

Altruistisches Verhalten ist ein fester Bestandteil im Leben von Menschen. Die Bereitschaft sich gegenseitig zu unterstützen ist durch unterschiedliche Motive gekennzeichnet. Manche Menschen helfen, ohne einen eigenen Nutzen daraus zu ziehen. Andere Menschen dagegen verhalten sich in gewissem Maße hilfsbereit, erwarten hierfür aber eine Gegenleistung. Die vorliegende Arbeit untersucht die altruistischen Verhaltensweisen von Studierenden verschiedener Fachrichtungen. Basierend auf der Technik der verlorenen Briefe wurde in einem Feldexperiment das altruistische Verhalten von Studierenden der Fakultät IV (Wirtschaft und Informatik) und der Fakultät V (Diakonie, Gesundheit und Soziales) der Hochschule Hannover untersucht. Dabei wurden Briefe an unterschiedlichen Stellen platziert und deren Mitnahme- und Rücklaufergebnis gemessen. Die Ergebnisse zeigen, dass Studierende der Fakultät IV (Wirtschaft und Informatik) eher zu altruistischem Verhalten neigen, als die durch ihren Studiengang vermeintlich stärker sozial geprägten Studierenden der Fakultät V (Diakonie, Gesundheit und Soziales). Ferner nimmt die Wahrscheinlichkeit eines altruistischen Verhaltens mit steigender Anzahl an anwesenden Personen ab.

Die Studie basiert auf einem Experiment, bei dem Einflussfaktoren auf Korruptionsbereitschaft untersucht wurden. Es wurden personale und situative Einflussfaktoren berücksichtigt. Mithilfe eines 2x2x2-Vignettendesigns wurden die situativen Einflussfaktoren operationalisiert und methodenkritisch überprüft, ob eine homogene Geschlechtswahl der Vignettenprotagonisten die Antworten der Versuchspersonen beeinflusst. Befragt wurden 171 Studierende der Betriebswirtschaftslehre. Es konnten keine statistisch signifikanten Effekte nachgewiesen werden, die schlussfolgern ließen, dass die Versuchspersonen in ihren Antworten durch die homogene Geschlechtswahl der Vignettenprotagonisten beeinflusst wurden. Die Versuchspersonen wählten ihre Antworten unabhängig davon, ob eine Vignette mit weiblichen Protagonisten oder eine Vignette mit männlichen Protagonisten vorlag.

In diesem Beitrag werden die Ergebnisse von sieben Datenhebungen zur Relevanz situativer Risikofaktoren für Korruption aus den Jahren 2010 bis 2013 vorgestellt. In fünf quantitativen Datenerhebungen wurden folgende sechs Faktoren untersucht: Dauer der Korruptionsbeziehung, Vorteilshöhe, Art der Vorteilsempfänger, Entdeckungswahrscheinlichkeit, Vorliegen einer persönliche Notlage und situative Unsicherheit. In zwei qualitativen Datenerhebungen wurde mit offenen Fragen nach situativen Einflussfaktoren von Korruption gefragt. Erwartungswidrig erwiesen sich die untersuchten Faktoren als weitgehend irrelevant für die Bewertung von Korruption sowie für das Meldeverhalten bei beobachteter Korruption. Zu vermuteten ist, dass situative Risikofaktoren nicht unmittelbar, sondern indirekt über vom Umfeld geteilte mögliche Rechtfertigungen korrupter Handlungen im Alltag wirken. Die durchgängig nicht signifikanten Ergebnisse lassen daran zweifeln, dass korruptes Handeln maßgeblich durch situative Risikofaktoren beeinflussbar ist.

Most studies of returned highly skilled migrants in China were guided by a national approach, emphasizing how the size and direction of the return migration were shaped by national policies and practices. What have been overlooked are the flows of returned skills at the municipal level where talent attraction and employment really take place. To fill this gap, the author conducted a comparative study of the returned highly-skilled migration in Beijing, Shanghai, Guangzhou and Shenzhen, the four most important cities in China. Based on in-depth interviews with returned skills from different countries and with various occupational backgrounds, complemented by the analysis of talent policies that have been issued by each city since the early 1990s and relevant statistical data, this study finds that, first, municipal cities tend to make ‘localized policies’ in order to suit local situation and to increase flexibility and efficiency in their effort of enticing of talents, demonstrating a wide range of variations not yet discussed in previous literature. It is thus crucial to pay timely attention to municipalities in order to obtain a more accurate and balanced picture of returned skilled migration in China. Second, the flow of returned skills shall be perceived in a broader analytical framework, in which the attractiveness to skills comes mostly from the long-term career potentials made possible by the industrial structure of individual city and mediated by social, cultural and geographical factors. It is only within this larger framework and through the interaction with other factors that government policies play their modulator roles.

Private school enrolment may lead to worse subsequent performance in further education or in the labour market. If students differ in their ability not only to pay but to take advantage of educational opportunities (“talent” for short), private schools attract a worse pool of students when publicly funded schools are better suited to foster progress by more talented students. In the data we analyze, the impact of observable talent proxies on educational and labour market outcomes is indeed more positive for students who (endogenously) choose to attend public schools than for those who choose to pay for private education.

Tendo Macau por contexto, quinze anos após a transferência da sua administração para a República Popular da China e cinco séculos de presença portuguesa, o estudo efetua uma abordagem às representações e estereótipos sociais dos portugueses, a partir de um inquérito a cento e setenta e cinco mulheres chinesas desta Região Administrativa Especial (RAEM). Tendo como marcos conceptuais a Teoria das Representações Sociais, de Moscovici, e a Teoria da Identidade Social, de Tajfel, o estudo procura explicitar os saberes sociais construídos por esse grupo de referência, determinantes na forma como se processa a comunicação e a interação grupal com portugueses e âncora para a construção de estereótipos com os quais esses processos são simplificados, mas também enviesados. Antevendo-se, num horizonte não muito longínquo, decisões quanto à manutenção do princípio “um país, dois sistemas”, que viabiliza a preservação de marcas portuguesas (como a língua) e uma abertura especial à presença de portugueses em Macau, a compreensão das imagens e metáforas sobre esta comunidade constitui estratégia relevante para a perspetivação, no presente como no futuro, das relações intergrupais que a envolvem. O estudo conclui que as representações sobre os portugueses são, no essencial, de pendor positivo e exibem uma abertura à proximidade social e à participação desta comunidade nas dinâmicas sociais da RAEM. Mas assinala também áreas de potencial maior conflitualidade na defesa, pelo endogrupo, de áreas vitais de afirmação dessa nova ordem social pós- transferência.
