This thesis aims to increase understanding of New Zealand consumer reactions to messages promoting genetically modified food products (GMFs) and to determine how the manipulation of three persuasion variables, message sidedness, source credibility and inward vs. outward focus impact upon consumer attitudes. To achieve this aim, the study integrated two frameworks, Bredahl's, (2001) determinants of attitudes towards GMFs and Wansink and Kim's, (2001) strategies for educating consumers about GMFs, into a new model. To empirically examine the model, a web-based experiment using a 2x2x2 between-subjects factorial design was conducted. The experiment exposed participants to one of eight treatment groups containing a promotional message for Genetically Modified foods. The participants then completed an on-line questionnaire detailing their responses to the messages. A total of 380 useable questionnaires were collected from a national sample of consumers and analysed using ANCOVA. The results of the study suggest that the outwardly focused, two-sided message was more powerful at lowering perceptions of risks, raising perceptions of benefits and positively influencing attitudes toward the ad than either the one-sided, outwardly focused message, or the inwardly focused messages of either sidedness condition. For purchase intentions individual differences appeared to be of greater influence than message factors.

The aim of this investigation was to determine whether there is a significant difference in the academic achievement of sixth grade Science students when teaching styles are matched to their learning styles. The research problem is encompassed in the following question: "Is there a relationship between matching teaching and learning styles and the academic success in Science?" A quantitative approach was undertaken, specifically, the pretest-posttest control group experimental design. The population comprised of sixth grade students selected according to a non-probability sampling method of convenience. The sample comprised of two class units randomly selected. The dependent sample t-test inferential statistic was used to analyze the data collected. The results indicated a statistically significant difference between the pretest and posttest scores of the experimental group. The conclusion reached is that matching teaching styles to learning styles improves the academic success of sixth grade learners in Science. / Educational Studies / M.Ed. (Educational Psychology)

The thesis called "Extended musical teaching in primary school" addresses the ini­tial idea of the author, professor Ladislav Daniel, since itś creation till its development in the last 45 elapsed years of its continuation in the Czech Republic. Based on this method this experimental research has taken place. This research will focus specifically on The 2nd primary school in Jindřichův Hradec where extended musical teaching has been in progress. The purpose of this activity is to find out how this school has dealt with extended teaching (the reason for its foundation, difficult situations during teaching, where is the musical education leading) and if this way of educating is comparable to professor Danielś method.

Plant removal experiments are useful to elucidate these mechanisms because its cause and effect response. This thesis aims to analyze experiments removal plants. The first paper presents a scientometric review of the literature on plant functional groups removal 1991. We verify aspects such as the number of publications and citations in journals indexed in the Web of Science, which country was made in order to detect bias and geographic gaps, which ecological effects were tested, which functional groups were removed, which removal methods and which environments were made. We found an increase in the number of publications and citations on average during this period, however, was 12 times lower than publications on functional diversity, perhaps due to the difficulty of conducting experiments. The work was mainly carried out in temperate climates where taxonomic knowledge is greater, in addition, there is a prevalence of vegetation that is most commonly removed than trees. Testing interactions, especially competition, was the main reason for removal, perhaps as a matter of historical competition is considered the interaction that influences the co-occurrence of species. The cut at ground was the major method of removing, undisturbing the soil and avoiding undesirable effects of herbicides, and few studies have been made in a greenhouse and in the natural environment at the same time, which could elucidate responses to natural conditions and at the same time responses specific interactions. In the second paper we carried a case study on removal of capim-flecha ( Tristachya leiostachya Ness.), a dominant grass in Emas National Park (ENP), and what the consequences of such removal to the co-occurring grasses. We expected that the absence of capim-flecha allow further growth of grasses, however we found no difference in mean values between treatments indicating that there is no competition influencing the abundance of capim-flecha. The historical context burned in PNE may have influenced this high dominance of capim-flecha. We believe that experiments are useful in testing interactions, especially if they are made in the natural environment and greenhouse at the same time. / As relações entre os organismos e os mecanismos que permitem sua coexistência são importantes questões em ecologia. Experimentos de remoção de plantas são úteis em elucidar esses mecanismos, devido sua capacidade de resposta do tipo causa e efeito. Esta dissertação se propõe a analisar experimentos de remoção de plantas. O primeiro artigo apresenta uma revisão cienciométrica das publicações sobre remoção de grupos funcionais de plantas, desde 1991. Verificamos aspectos como o número de publicações e citações em periódicos indexados no Web of Science, em qual país foi feito, visando detectar vieses e lacunas geográficas, quais efeitos ecológicos testados, quais grupos funcionais removidos, quais os métodos de remoção e em quais ambientes foram feitos. Encontramos um crescimento no número de publicações bem como na média de citações nesse período, contudo foi 12 vezes menor do que publicações sobre diversidade funcional, talvez devido à dificuldade de realizar experimentos. Os trabalhos foram realizados principalmente em climas temperados onde o conhecimento taxonômico é maior, além disso, há um predomínio de vegetação rasteira que é mais comumente removida do que árvores. Testar interações, principalmente competição, foi o principal motivo de remoção, talvez por uma questão histórica de competição ser considerada a interação que mais influencia a co-ocorrência de espécies. O corte rente ao solo foi o principal método de remoção, evitando revolver o solo e efeitos indesejáveis de herbicidas, e poucos trabalhos foram feitos em casa de vegetação e ambiente natural ao mesmo tempo, o que poderia elucidar respostas à condições naturais e ao mesmo tempo respostas específicas de interações. No segundo capítulo fizemos um estudo de caso sobre remoção de capim-flecha (Tristachya leiostachya Ness.), uma gramínea dominante no Parque Nacional das Emas (PNE), e quais as consequências dessa remoção para as gramíneas co-ocorrentes. Esperávamos que a ausência do capim-flecha permitiria um maior crescimento das gramíneas, contudo não encontramos diferença nos valores das médias entre os tratamentos o que indica que não há competição influenciando a abundância do capim-flecha. O contexto histórico queimadas no PNE pode ter influenciado essa alta dominância do capim-flecha. Consideramos que experimentos são úteis em testar interações, sobretudo se forem feitos em ambiente natural e casa de vegetação ao mesmo tempo.

Cette thèse s’inscrit dans le système complexe de la formation par alternance des adultes avec une initiation à l’autoévaluation. Quels sont les éléments qui participeraient aux changements initiés par la loi de Refondation pour pallier les inégalités scolaires constatées ? Notre objet d’étude se situe hors de l’école en REP, avec un dispositif d’accompagnement à la scolarité qui prend en charge des enfants de 7 ans en difficulté scolaire : le CELEM (Club Lecture Ecriture Mathématiques). Bien que des études s’intéressent à l’impact de différents facteurs sur la réussite des enfants, les recherches qui permettent la validation des modèles d’évaluation formatrice sont rares. Nous proposons une initiation à l’autorégulation lors de la formation des intervenants des clubs afin de favoriser le développement cognitif et l’autonomie des adultes et par la suite des enfants. Notre méthodologie a pour objectif de tester une relation causale entre la formation des intervenants et la progression des enfants pour des disciplines scolaires et dans le comportement. Notre méthode est quasi expérimentale, comparative, prospective en quasi double aveugle. Deux groupes d’intervenants ont été constitués par randomisation. Les cartes associatives réalisées ont permis de suivre l’évolution des représentations que les intervenants se font de leur mission. Les résultats obtenus sont positifs et ont été corroborés par les résultats des enfants. On a constaté des modifications statistiquement significatives qui permettent d’affirmer que l’initiation à l’autorégulation des intervenants a entraîné des modifications de leurs représentations et l’amélioration des résultats des enfants. / This thesis falls within the complex system of the work/study training program of adults with an introduction to self-regulation. Which elements would participate to the changes initiated by the law of Reorganization to compensate the existing educational inequalities? Our subject is set outside school in the high-priority education network, within a plan of educational support for seven-year-olds with learning difficulties : the Reading Writing Mathematics Club. Though several studies take interest in the impact of various factors on the children’s success, little research has been done to validate the models of formative evaluation. We propose to improve the training of the Club’s staff members with an introduction to self-regulation, to stimulate the cognitive development and independence of both adults and children. Our methodology aimed to test a cause and effect relation between the staff's training and the children’s progress in both school subjects and behaviour. Our method was almost experimental, comparative, prospective, practically double blinded. Two staff groups were randomly formed. We observed how the representations they had of their own mission evolved, before and after their training; the obtained results were corroborated by the children’s results. We observed statistically significant differences which allow us to affirm that the training in self-regulation of the staff members changed their representations and led to better results for the children

Weirs belong to the basic water structures mainly creating vertical contraction of stream against the flumes, which creating mainly horizontal contraction of stream. In the case of the flow over weir usually occurs change from subcritical flow over critical with critical depth to supercritical flow, therefore overflow. Weirs with rectangular control section are described rectangular longitudinal and transverse profile and horizontal crest. Can be distinguish three basic inflow directions to weir. The first is frontal inflow, which is the most frequent in practice. The second is lateral inflow used in distribution and consumption objects. The third is lower inflow used as laboratory weirs, weirs with deeply submerged wall, etc. In terms of knowledge of influence listed directions of inflows, currently are not sufficiently researched the cases of frontal inflow with side contraction and lower inflow on all types of weirs. Due to extent of the issue, labour is focused only on frontal inflow over broad-crested weir with side contraction and lower inflow over broad-crested weir without side contraction. The goal of the labour was to summarize the current knowledge of the flow over broad-crested weir with side contraction and lower inflow over broad-crested weir without side contraction, describe the character of the flow at the overflow and on the basis of it determine recommendations for measurement and calculation of discharge. Further to define unexplored area, specify methods of solution and verify own measurements. The research dealt with application and optimal numerical model setting for to solve the problem.

[pt] A tese investiga os princípios da pesquisa experimental para a criação de objetos em harmonia com o meio ambiente físico e social. A base para este estudo é a pesquisa realizada no Laboratório de Investigação em Livre Desenho (LILD) da PUC-Rio. Defendemos a tese de que a metodologia experimental para a pesquisa dessas técnicas se beneficia tanto de elementos da cultural material pré-industrial, quanto de técnicas informatizadas e do conhecimento universitário moderno. A partir do encontro desses diferentes saberes, a pesquisa experimental pode enriquecer seus parâmetros e ter maior potencial para a geração de objetos em harmonia com o meio ambiente físico e social. A tese conta com o resultado da pesquisa em dois campos - uma aldeia indígena na Amazônia e o laboratório CPI (Construction Process Investigation), da Universidade do Havaí. Também é feita a descrição de oficinas realizadas para o compartilhamento de técnicas desenvolvidas no laboratório. A partir dos elementos, apresentamos um debate acerca da pesquisa e do desenvolvimento de objetos em harmonia com o meio ambiente físico e social e concluímos que o encontro entre os conhecimentos da cultura material de sociedades pré-industriais e da pesquisa acadêmica ligada à indústria potencializa a metodologia da pesquisa de técnicas em harmonia com o meio ambiente físico e social. / [en] This thesis investigates the principles of the experimental research for the creation of objects that are in harmony with the physical and social environments. The base for this study is the research done in the Laboratório de Investigação em Livre Desenho (LILD). We defend the idea that the experimental methodology in this kind of research is enrichened both by elements of pre-industrial material culture and by modern academic knowledge. With these different knowledges, experimental research can enrich its parameters and have greater potential to create objects in harmony with the physical and social environments. Thus, the thesis has the result of two fiel researches - and indigenous village in the Amazon and the CPI (Construction Process Innovation) lab of the University of Hawaii. There is also a description of workshops that have been done to share the techniques developed in the laboratory. Based on these elements, we present a discussion about the experimental research and about the development of objects in harmony with the physical and social environments, and we come to the conclusion that the integration of elements of pre-industrial societies and of academic research related to the industry favors to the development of the methodology for research of techniques in harmony with the physical and social environments.
