Essays on Life Insurer Demutualizations and Diversifying Mergers and Acquisitions
Creators: name: Erhemjamts, Otgontsetseg
Publisher: name: Georgia State University
Year: 2005

description: One outcome of ever increasing competition and consolidation in the financial services industries has been the declining significance of the mutual organizational form in the U.S. life insurance industry. The process of converting from a mutual to a stock company gives rise to a variety of issues. The first three essays in this dissertation focus on the growing movement toward demutualization in the U.S. life insurance industry where essay one discusses industrial organization background. In essay two, I improve on the existing literature regarding the determinants of life insurer demutualizations by investigating an expanded data set and utilizing more robust econometric techniques to allow for different forms of demutualization. I also model the demutualization process as a two step process to account for the timing of demutualization, time-varying covariates, and censoring. These models yield results that strongly support the access to capital hypothesis. In essay three, I examine changes in risk management and investment strategies of demutualizing life insurers following conversion. The empirical tests reveal that demutualizing life insurers increase total risk after conversion consistent with their increased abilities and incentives for risk taking. They achieve this increase by hedging interest rate risk and increasing their core-business risks as proxied by investments in various illiquid asset classes. The final essay is on diversifying mergers and acquisitions. Conventional wisdom suggests diversification reduces risk. However, the change in the riskiness of the firm after diversifying acquisitions has not been directly tested in the literature. Using a sample of diversifying M&As, I find that total firm risk does not decrease significantly after these transactions. I then show that while total firm risk does not change, core-business risk increases significantly after the diversifying M&A transactions. I also find that capital expenditures in the acquirers? core business segments increase significantly more after diversifying transactions relative to that of non-diversifying transactions. Overall, the evidence in this essay adds to the risk management literature that says hedging is a means of allocating risk rather than reducing risk and offers an alternative explanation for why firms diversify.

CEO Turnover and Divisional Investment

Publisher: name: Georgia State University

description: This paper examines the impact of CEO turnover from an internal capital allocation perspective. We test whether new CEOs make different divisional investment decisions than their predecessors, and if yes, how would this difference affect firm performance. We find that segment investments respond to factors, such as segment investment opportunity, segment cash flow, and other segments? cash flows, differently after CEO turnover. Evidence also indicates that new CEOs adjust the segments? previous over-investment /under-investment status to match industry average investment level, and they adjust the relative investment preference among divisions. These findings support the argument that different CEOs have their own set of skills and incentives, which directly affect their internal capital allocation decisions after they take over the office. We also examine the affiliation relationship between certain divisions and new CEOs, and find that new CEOs do not make capital allocation in favor their affiliated divisions. Furthermore, the analyses on firm-level internal capital allocation sensitivity do not support the literature about positive relationship between firm performance and the ?Q-sensitivity?. But, our analyses do find a positive and robust relationship between changes in firm performance and changes in the ?cash flow-sensitivity?. This suggests that new CEOs making internal capital allocation in favor of their ?cash cow? segments are more likely to improve firm performance after CEO turnover.

description: Most solid tumors are aneuploid, carrying an abnormal number of chromosomes, and they frequently missegregate whole chromosomes in a phenomenon termed chromosome instability (CIN). While CIN can be provoked through disruption of numerous mitotic pathways, it is not clear which of these mechanisms are most critical, or whether alternative mechanisms could also contribute significantly in vivo. One difficulty in determining the relative importance of candidate CIN regulators has been the lack of a straightforward, quantitative assay for CIN in live human cells: While gross mitotic abnormalities can be detected visually, moderate levels of CIN may not be obvious, and are thus problematic to measure. To address this issue, we have developed the first Human Artificial Chromosome (HAC)-based quantitative live-cell assay for mitotic chromosome segregation in human cells. We have produced U2OS-Phoenix cells carrying the alphoidtetO-HAC encoding copies of eGFP fused to the destruction box (DB) of anaphase promoting complex/cyclosome (APC/C) substrate hSecurin and sequences encoding the tetracycline repressor fused to mCherry (TetR-mCherry). Upon HAC missegregation, daughter cells that do not obtain a copy of the HAC are GFP negative in the subsequent interphase. The HAC can also be monitored live following the TetR-mCherry signal. U2OS-Phoenix cells show low inherent levels of CIN, which can be enhanced by agents that target mitotic progression through distinct mechanisms. This assay allows direct detection of CIN induced by clinically important agents without conspicuous mitotic defects, allowing us to score increased levels of CIN that fall below the threshold required for discernable morphological disruption.

description: The CLIL (Content and Language Integrated Learning) approach is still sparse in Portugal, being implemented only in a few schools. Despite this panorama, a Portuguese school developed the project English Plus based on the CLIL approach, which was implemented with a class of 7th grade students, and combined the non-linguistic subject of History with English as a Foreign Language. In order to sustain the project, the school established partnerships, namely with a Higher Education Institution. One of this institution’s tasks was the monitoring of the project, particularly regarding the opinions of students, tutors/parents, teachers and school managers about it. This article presents a description of such opinions collected by means of questionnaires and interviews. The main findings indicate that the several educational actors seem to have a confluent opinion of the potentialities of the project and the CLIL approach, particularly in terms of: students’ development of linguistic and communicative competences, attitudes towards languages and Otherness, and increasing knowledge of History; teachers’ professional development; the overall community’s (particularly, the tutors/parents) interest and participation in the school activities; the creation of interdisciplinary synergies within school and implementation of networks and partnerships with society.

description: Considerando que Instituições de Ensino Superior são espaços onde o conhecimento científico é produzido e disseminado, apresenta-se um estudo de caso da Universidade de Aveiro, Portugal, que pretende descrever práticas e discursos institucionais relativamente à utilização das línguas na investigação científica. Para descrição das práticas, foram recolhidos e analisados Relatórios Anuais das Unidades de Investigação da Universidade de Aveiro. Para acesso aos discursos institucionais, foram entrevistados oito atores institucionais, responsáveis pela investigação científica e pelo governo e coordenação da instituição. Os resultados apontam para uma convergência entre as práticas investigativas e os discursos institucionais relativamente ao papel e estatuto que as diferentes línguas adquirem na investigação científica: a língua inglesa surge, tanto nas práticas como nos discursos, como primordial para o processo de internacionalização da ciência; por outro lado, as outras línguas são percecionadas enquanto barreiras a essa internacionalização e ao sucesso científico-profissional do investigador.

description: Aiming to characterize the way Portuguese Public Higher Education Institutions use Communication Technologies (CTs), the on-going project at University of Aveiro TRACER will apply a national online survey, therefore developing a prior pilot-study undertaken with validation purposes. This paper describes and summarizes part of the work developed within the pilot-survey, which includes a theoretical review outlining the context of CTs use and its impact on teacher training. First results of the pilot-study, which included four institutions, will be used to present institutional perspectives about CT use. The responses cannot be generalized as wide-reaching statements, but they already reveal that higher education institutions are making an effort to bring together policies and practices. Also, there seems to be a common awareness and concern about teacher training in this area, although training main topics and modalities seem to vary significantly. Results show that despite the uneven spread of responses about the existence of a formal political strategy concerning CT, there is an institutional investment (currently and foreseen in a near future) on CTs, namely on teacher training for CTs use.

description: A abordagem ao currículo one-size-fits-all é ineficaz e segregadora e, para muitos discentes, está repleto de barreiras. Os alunos não aprendem todos do mesmo modo, não se expressam da mesma forma e não estão motivados para a aprendizagem da mesma maneira. Um currículo projetado universalmente responde à diversidade existente nas salas de aula e é desenhado, desde o início, para atender às necessidades de um maior número de alunos. Proporciona ainda aos docentes a escolha de uma variedade de opções, ferramentas e estratégias que estão embutidas no currículo e nos materiais didáticos. O Universal Design for Learning tem a sua origem e inspiração no conceito de Design Universal aplicado à arquitetura, que preconiza que as adaptações realizadas para responder às necessidades das pessoas com deficiência, tendem a beneficiar todos. Preconiza o desenho de um currículo de forma a incluir objetivos, métodos, materiais e avaliações que apoiem os alunos, através da redução de barreiras e, simultaneamente, providenciando um apoio efetivo à aprendizagem. É, portanto, uma conceção inovadora e com um enorme potencial, merecedora de investigação aprofundada, que nos parece relevante para uma escola e uma educação inclusivas, cujo contributo pretendemos ventilar neste documento.

description: In this paper we test the idea that citizens can be stimulated to vote in an election via subtle psychological processes, which have little or nothing to do with the act of voting as such. More specifically, we argue that presenting voters with stimuli that induce an active mood will increase their tendency to vote. We conducted an experiment to test our ideas. Participants were subtly primed by giving them a campaign leaflet that contained a word puzzle, which included words that are associated with either action or inaction. The results indicate that subtly primed participants in the action condition reported stronger voting intentions than those in the inaction condition. These findings suggest that individuals can indeed be stimulated (or inhibited) to vote through subtle psychological processes. We discuss the implications of our results for the study of voting behaviour as well as campaigns aimed at electoral mobilization.
Efficiency Implications of Corporate Diversification: Evidence from Micro Data

description: In this study we contribute to the ongoing research on the rationales for corporate diversification. Using plant-level data from the U.S. Census Bureau, we examine whether combining several lines of business in one entity leads to increased productive efficiency. Studying the direct effect of diversification on efficiency allows us to discern between two major theories of corporate diversification: the synergy hypothesis and the agency-cost hypothesis. To measure productive efficiency, we employ a non-parametric approach?a test based on Varian?s Weak Axiom of Profit Maximization (WAPM). This method has several advantages over other conventional measures of productive efficiency. Most importantly, it allows one to perform the efficiency test without relying on assumptions about the functional form of the underlying production function. To the best of our knowledge, this study is the first application of the WAPM test to a large sample of non-financial firms. The study provides evidence that business segments of diversified firms are more efficient compared to single-segment firms in the same industry. This finding suggests that the existence of the so-called ?diversification discount? cannot be explained by efficiency differences between multi-segment and focused firms. Furthermore, more efficient segments tend to be vertically integrated with others segments in the same firm and to have been added through acquisitions rather than grown internally. Overall, the results of this study indicate that corporate diversification is value-enhancing, and that it is not necessarily driven by managers? pursuit of their private benefits.

Las opciones pueden ir desde la administración del proceso educativo, a la evaluación o la comunicación. Sin embargo, una de las opciones más importantes de todas, es la oportunidad que las TIC ofrecen en el acceso a la información y a la participación para aquellos estudiantes que de otra forma les sería imposible, principalmente los denominados estudiantes o alumnos con necesidades educativas especiales (NEE). Se ha demostrado en repetidas ocasiones que el uso de las TIC puede tener un impacto positivo en la experiencia de aprendizaje de estos alumnos, asumiendo el uso de estas herramientas como estrategia educativa especializada que apoya la inclusión académica, cultural y social. Como sucede en la educación en términos generales, pero tal vez con mayor relevancia en el ámbito de la Educación Especial (EE), las TIC son asumidas como herramientas importantes al servicio de los profesores y estudiantes para superar las barreras y promover la adquisición de habilidades. Este documento presenta una revisión de bibliografía relevante en el campo de las TIC y su aplicación en el ámbito de la Educación Especial y la atención a alumnos con Necesidades Educativas Especiales. Finalmente se presenta una tabla resumen con las principales soluciones TIC categorizadas en función del tipo de discapacidad de los estudiantes.

description: UPLC-DAD method was developed and validated for the quantitative determination of free flavonol aglycones (kaempferol, quercetin and myricetin) after acidic hydrolysis in six Lysimachia species. Quantitative analyses showed that the amounts of various flavonol aglycones were significantly different in Lysimachia vulgaris, Lysimachia nummularia, Lysimachia punctata, Lysimachia christinae, Lysimachia ciliata and Lysimachia clethroides. The L. clethroides sample was found to be the richest in kaempferol (25.77 ± 1.29 μg/mg extract) and quercetin (97.67 ± 4.61 μg/mg extract), while the L. nummularia sample contained the highest amount of myricetin (20.79 ± 1.00 μg/mg extract). The antioxidant capacity of hydrolysed extracts was evaluated using in vitro DPPH• (2,2-diphenyl-1-picrylhydrazyl) and ABTS•+ [2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)] decolourisation tests. The observed radical scavenging capacities of the extracts showed a relationship with the measured flavonol aglycone content and composition. The acidic treatment resulted in an increased free radical scavenging activity compared to the untreated methanol extract.

Two fingerprints for each cultivar, based in 6 groups of aroma compounds before and after acidic hydrolysis of the musts were obtained by Multiple Variable Analysis. Only 17 aroma compounds before and 21 after hydrolysis, were selected by their high discriminating power. The Principal Component Analysis carried out with data of these selected compounds provided two components explaining 85.11 % of the overall variance for free aroma compounds and 87.58 % for those obtained after hydrolysis of musts, allowing an objective differentiation of each cultivar.

description: I find evidence of predictability in out-of-sample data for four risk premia using simple econometric models. Two factor return models are used, an APT model and the Wilshire Atlas.  I demonstrate that investors can exploit conditioning information to manage their exposures to risk factors. The results suggest that the investment opportunities set changes in a large and an economically significant way.  I show that the growth rate in money supply and trend in stock market valuations are the main drivers respectfully of the risk premia associated with the Book-to-Market and Size factors from the Wilshire model.  The predictability results are mixed with respect to Business Cycle Theory. At times investors price business cycle risk while at other times they exhibit herding tendencies.

description: Given a grid of cells each having an associated cost value, a raster version of the least-cost path problem seeks a sequence of cells connecting two specified cells such that its total accumulated cost is minimized. Identifying least-cost paths is one of the most basic functions of raster-based geographic information systems. Existing algorithms are useful if the path width is assumed to be zero or negligible compared to the cell size. This assumption, however, may not be valid in many real-world applications ranging from wildlife corridor planning to highway alignment. This paper presents a method to solve a raster-based least-cost path problem whose solution is a path having a specified width in terms of Euclidean distance (rather than by number of cells). Assuming that all cell values are positive, it does so by transforming the given grid into a graph such that each node represents a neighborhood of a certain form determined by the specified path width, and each arc represents a possible transition from one neighborhood to another. An existing shortest path algorithm is then applied to the graph. This method is highly efficient, as the number of nodes in the transformed graph is not more than the number of cells in the given grid and decreases with the specified path width. However, a shortcoming of this method is the possibility of generating a self-intersecting path which occurs only when the given grid has an extremely skewed distribution of cost values.

Two Essays on Investor Sentiment and Equity Offerings
Creators: name: Chiu, Hsin-Hui
Publisher: name: Georgia State University
Year: 2006

description: Using monthly open-end mutual fund flows as a proxy for investor sentiment, I am able to examine the impact of sentiment on IPO volume and underpricing. I find that issuers? filing decisions are significantly affected by the predicted future sentiment around the expected IPO dates. Furthermore, sentiment has an impact on the final offer price setting and over-allotment options exercised. While previous research documents IPO cycles with respect to other proxies for investor sentiment, I am able to examine IPO cycles and underpricing with respect to sentiment along with investor risk preferences. I hypothesize that a going public firm will try to issue its IPO when investor risk preferences are favorable to the firm?s own risk characteristics. Empirical results based on 5,661 initial public offerings between 1986 and 2004 are consistent with my hypotheses that issuers not only time the market with sentiment in general, but also attempt to incorporate investor risk preferences into their going public decisions. Furthermore, underpricing is more severe when firms issue equity during months with large inflows into equity mutual funds. In my second essay, I find that SEO firms appear to time market efficiently because of the shorter filing periods compared to the average 2-3 months of the IPOs. Also, sentiment not only affects a SEO offer price setting but also affects the over-allotment options exercised. I examine two subgroups of the SEO samples: shelf registration and non-shelf SEOs. I find that shelf-registered SEOs incorporate investor sentiment into offering price to a greater degree compared to regular SEOs. Lastly I find that investor risk preference plays a role in firms? decision to file prospectuses with the SEC. In other words, firms rationally decide the timing of filing based on the predicted investor preference and try to match firm characteristics with investor preference around the expected SEO date.

description: This article applies error propagation in a Monte Carlo simulation for a spatial-based fuzzy logic multi-criteria evaluation (MCE) in order to investigate the output uncertainty created by the input data sets and model structure. Six scenarios for quantifying uncertainty are reviewed. Three scenarios are progressively more complex in defining observational data (attribute uncertainty); while three other scenarios include uncertainty in observational data (position of boundaries between map units), weighting of evidence (fuzzy membership assignment), and evaluating changes in the MCE model (fuzzy logic operators). A case study of petroleum exploration in northern South America is used. Despite the resources and time required, the best estimate of input uncertainty is that based on expert-defined values. Uncertainties for fuzzy membership assignment and boundary transition zones do not affect the results as much as the attribute assignment uncertainty. The MCE fuzzy logic operator uncertainty affects the results the most. Confidence levels of 95% and 60% are evaluated with threshold values of 0.7 and 0.5 and show that accepting more uncertainty in the results increases the total area available for decision-making. Threshold values and confidence levels should be predetermined, although a series of combinations may yield the best decision-making support.
Deposit Insurance: Is it Good for the Development of Financial Markets?

description: Deposit Insurance: Is it good for the development of Financial Markets?  BY  Kaysia Therese Campbell  April 25, 2006  Committee Chair: Dr. Stephen Smith and Dr. James Owers  Major Department: Finance  The literature on deposit insurance has focused primarily on the role it plays in promoting banking sector stability and growth, while little attention has been placed on its possible effect on the development of other markets. Failure to examine the impact of deposit insurance on other markets could lead to premature conclusions about the full effect it has on total financial market development and, in turn, economic growth. Using panel data and cross sectional averages on 96 countries covering the time period 1975 ? 2004 to distinguish between short run and long run effects, and including a host of controls, I find evidence that deposit insurance is associated with greater long run, total financial market development, as measured by the size and activity of banks, equity markets, bond markets and non-bank financial intermediaries. This indicates that it is able to accelerate banking sector development without necessarily retarding the development of other markets so that overall financial market development is improved. It is important to note that this is primarily evident for countries with a strong legal and contracting environment. The results also suggest that the immediate impact of deposit insurance is greatest for middle income economies but over time there is no clear evidence that this persists. Using design features thought to contribute to the generosity and ability of the scheme to curb moral hazard and provide a credible guarantee, I construct two indices to summarize the various design features and examine their impact on financial market development. I find that countries adopting more credible schemes appear to have smaller and less active markets over time. However the results also indicate that more credible and generous design features are better able to promote total market activity in the long run. The hopeful conclusion to be made from this study is that the positive influence of deposit insurance on the banking sector is translated into the entire financial market system over time and may be irrespective of a country?s particular stage of economic development.

description: A correta construção de significados relativos ao conceito de números racionais pelos alunos revela-se de fundamental importância para uma sólida construção do conceito de número, para o sucesso no prosseguimento dos estudos e para resolver os problemas do dia-a-dia da vida moderna. Portanto, a inadequada apropriação e aplicação destes conceitos por parte dos alunos revela-se problemática. Na origem da dificuldade dos alunos, identificam-se aspetos inerentes à complexidade do conceito e a uma débil e fragmentada abordagem na escola, frequentemente limitada pela escassez e inadequada exploração de materiais didáticos apropriados. Neste contexto, criou-se uma sequência didática, corporizada num conjunto de tarefas e de materiais que suportam a sua resolução, que se pretende constituir um continuum do estudo dos racionais, projetado desde o Ensino Pré-Escolar. A mesma, que foi sendo sucessivamente implementada (em contextos da formação principalmente contínua de professores e com os respetivos alunos), avaliada e reformulada até à sua versão definitiva, contribuiu para uma mais sólida apropriação dos conceitos subjacentes aos racionais pelos respetivos alunos.

description: No sentido de perceber se a criatividade quando aplicada nas práticas letivas de matemática poderá ou não marcar a diferença na formação dos educadores e dos professores e, consequentemente, na formação dos mais novos, preparámos uma ação de formação destinada a educadores de infância e professores do 1.º ciclo do ensino básico. A metodologia de trabalho e as tarefas criadas para essa ação foram pensadas de modo a fomentar a criatividade. Efetuámos quatro estudos de caso múltiplos (os grupos de trabalho nas sessões) e posteriormente, quatro estudos de caso individuais com duas educadoras e duas professoras. Neste artigo apresentamos os dois estudos de caso relativos às duas educadoras.

description: Evidenciando a relevância do papel da inter-relação entre a escola e espaços de educação não formais, associada a experiências criativas e inovadoras de aprendizagem, apresenta-se um estudo desenvolvido com alunos de 4º ano do 1º Ciclo do Ensino Básico, tomando como problemática de investigação compreender em que medida a realização de atividades práticas no Jardim do Paço de Castelo Branco estimula a aprendizagem das ciências/matemática e se repercute nas aprendizagens de âmbito curricular. Nessa perspetiva, construímos e validámos recursos didáticos cujo objetivo é promover aprendizagens em ciências/matemática, realizadas num ambiente de educação não formal, complementando os espaços formais com aspetos decorrentes da relação com o meio social e cultural. Apresenta-se e analisa-se uma das atividades propostas numa visita de estudo ao Jardim do Paço desenvolvida com base na observação e medição das sombras dos alunos. Em termos de envolvimento afetivo e de atitudes, os resultados foram muito positivos e relevantes, tendo, igualmente, ocorrido aprendizagens significativas e contextualizadas, ao nível de conhecimentos e de capacidades.

description: Pretendemos discutir as oportunidades que os espaços de educação não formal oferecem para a implementação de um ensino e aprendizagem que evidencie a utilização da matemática em contextos sociais e culturais. A discussão apoia-se num estudo desenvolvido no âmbito da Prática de Ensino Supervisionada no 4.º ano do 1.º Ciclo do Ensino Básico e em que se planeou, implementou e avaliou uma visita ao Jardim do Paço de Castelo Branco. Para apoiar a visita foi criado um conjunto de tarefas que, a par de visarem uma aprendizagem ativa da matemática, pretendiam despertar os alunos para a presença desta no mundo que nos rodeia. Apresentamos uma das tarefas propostas aos alunos no Jardim do Paço e analisam-se e discutem-se os resultados da atividade, bem como os textos e os desenhos livres realizados, após a visita, em sala de aula. A resolução da tarefa requereu dos alunos a mobilização e aplicação de conhecimentos matemáticos em contextos reais, contribuindo para aprendizagens contextualizadas. O empenho, a alegria e a motivação manifestada pelos alunos na realização das atividades apontam para uma forte interação entre os dois contextos, formal (escola) e não formal (Jardim do Paço de Castelo Branco).

description: As decisões financeiras constituem grande parte das deliberações tomadas ao longo da vida de um cidadão. Muitas implicações negativas podem resultar de uma inadequada atitude, comportamento ou ação nesta área. A educação financeira (EF) revela-se numa vertente cada vez mais essencial na formação individual e até social, ganhando assim uma importância e relevância incontestável na sociedade, ao dotar os indivíduos de conhecimentos que lhes permitem responder mais eficazmente a situações quotidianas. A par de inúmeras organizações nacionais e internacionais, também o Projecto Matemática Ensino (PmatE) se tem vindo a debruçar na identificação de oportunidades e no desenvolvimento de estratégias, de forma de estimular o interesse pela aprendizagem na área da EF e assim aproximar o ensino às necessidades atuais de formação para a cidadania. Dada a transversalidade do tema, analisaram-se os conteúdos promulgados nos programas escolares e curriculares do Ministério da Educação (ME) e identificaram-se alguns indicadores que apontam caminhos e focos programáticos através dos quais poderá ser possível despertar nos alunos o interesse para a EF. Neste sentido, têm sido desenvolvidos recursos pedagógico-didáticos, além de existir também um enorme investimento em conferências, seminários e oficinas sobre o tema. O presente artigo pretende apresentar algumas das iniciativas, práticas criativas e produtos desenvolvidos para o ensino básico na área da literacia financeira (LF) pelo PmatE, em diversos formatos, físico, mas também multimédia, não descurando a importância e impacto atual das novas tecnologias na sociedade.

description: Conclusion: The two discovered mutations in COL1A1 gene, although first reported in China, are recurrent ones that have also been found elsewhere in type I osteogenesis imperfecta patients, suggesting their role in pathogenesis of Van der Hoeve syndrome. Objectives: The aim of this study is to find mutational patterns of COL1A1 gene that may account for the putative Van der Hoeve syndrome in the patients carrying symptoms of osteogenesis imperfecta, blue sclera, and conductive deafness. Method: Genomic DNA was extracted from the blood of each patient and exons of COL1A1 gene were amplified using PCR and sequenced. Results: Sequencing in some of the two family members revealed point mutations in exon 26 (c.1792C > T) and exon 43 (c.3076C > T) of COL1A1 gene, respectively.

description: Face às mudanças sociais e comunicativas atuais, torna-se cada vez mais imprescindível a sensibilização à diversidade linguística e cultural de crianças em idade do pré-escolar, para que estas, desde cedo, desenvolvam competências pessoais, culturais e linguísticas que lhes permitam desenvolver o gosto pelas diferentes línguas e culturas e atitudes de respeito face ao Outro. Neste âmbito, o jogo apresenta-se como uma via promissora para as crianças se aproximarem das línguas e das culturas. O estudo aqui apresentado segue uma metodologia qualitativa de tipo investigação-ação e resulta da confluência dos trabalhos de Autor (data) e Autor (data), que tiveram por base o mesmo projeto pedagógico-didático. Tem como questão orientadora: Qual o contributo da abordagem da Sensibilização à Diversidade Linguística e Cultural através do jogo para o desenvolvimento das competências plurilingue e intercultural de crianças em idade pré-escolar? Os principais resultados apontam para as potencialidades do projeto de intervenção ao nível da construção de conhecimentos sobre o mundo das culturas e do desenvolvimento de capacidades nas esferas plurilingue e intercultural (tais como, estabelecimento de comparações entre línguas e culturas) e do ponto de vista socioafetivo.
