A multiculturalidade na disciplina de educação moral e religiosa católica

Desde sempre que a convivência entre pessoas e grupos de culturas e etnias diferentes se tem revelado difícil, e as grandes e profundas alterações na sociedade europeia têm vindo a alterar um pouco os paradigmas a que estávamos habituados em termos de convivência entre as pessoas, revelando uma sociedade com um tecido cada vez mais multicultural. Assim, torna-se pertinente uma educação que seja marcadamente multicultural. Entendemos que o conceito de multiculturalidade deve estar mais presente, aliás, na forma como se faz e pensa a educação hoje, por isso, é nosso entendimento, que é necessário rever mesmo a génese profunda do ato educativo e tudo o que isso implica na atualidade, pois não é possível pensar a educação e a escola hoje desligando-a da sua realidade multifacetada e multicultural. A disciplina de EMRC (Educação Moral e Religiosa Católica) é uma disciplina que tem já uma longa história de implementação no sistema de ensino português, existindo em quase todas as escolas do Ensino Básico e Secundário, por direito próprio ao abrigo da Concordata celebrada entre o Estado Português e a Santa Sé em 7 Maio de 1940 e ratificada em 18 Maio de 2004. A Disciplina de EMRC encontra-se assim incluída na matriz curricular do nosso sistema de ensino. Uma vez que a implementação da Disciplina de EMRC é da responsabilidade da Igreja Católica e tendo em linha de conta os valores e princípios naturalmente inerentes ao cristianismo, é legítimo supor a pertinência desta disciplina para uma educação e convivência multiculturais. O presente estudo pretendeu investigar o modo como a disciplina de EMRC contribui para uma educação multicultural. Propusemo-nos para isso encontrar, através de uma revisão da literatura, os principais elementos que constituem uma verdadeira educação, e neste sentido, definir a relação entre a escola e a multiculturalidade, e assim, contextualizar a educação multicultural. A tarefa seguinte foi a de comparar o conceito e a realidade da educação multicultural com o programa de EMRC. Procurámos complementar este estudo com a aplicação de um questionário a uma amostra significativa de professores de EMRC da Diocese de Lisboa, instrumento este que foi construído a partir da análise da literatura efetuada e tendo por base, sobretudo, o programa curricular, os manuais da disciplina e outros documentos relevantes para o tema em estudo. Pretendemos aferir o grau de importância dada pelos docentes à educação multicultural através da disciplina de EMRC, pelo menos nas escolas onde se verifique uma grande diversidade étnica. Para consolidar o estudo, foi também realizada uma entrevista a alguns professores e informantes – chave com destaque para a Disciplina. Pretendeu-se ainda investigar o grau de sensibilidade dos professores para uma verdadeira educação multicultural e as limitações encontradas por eles no programa e respetiva prática pedagógica, nomeadamente na sua ação como professores de EMRC e, eventualmente, a formulação de possíveis sugestões.

Orthogonal models, structure crossing, nesting and inference

We intend to study the algebraic structure of the simple orthogonal models to use them, through binary operations as building blocks in the construction of more complex orthogonal models. We start by presenting some matrix results considering Commutative Jordan Algebras of symmetric matrices, CJAs. Next, we use these results to study the algebraic structure of orthogonal models, obtained by crossing and nesting simpler ones. Then, we study the normal models with OBS, which can also be orthogonal models. We intend to study normal models with OBS (Orthogonal Block Structure), NOBS (Normal Orthogonal Block Structure), obtaining condition for having complete and suffcient statistics, having UMVUE, is unbiased estimators with minimal covariance matrices whatever the variance components. Lastly, see ([Pereira et al. (2014)]), we study the algebraic structure of orthogonal models, mixed models whose variance covariance matrices are all positive semi definite, linear combinations of known orthogonal pairwise orthogonal projection matrices, OPOPM, and whose least square estimators, LSE, of estimable vectors are best linear unbiased estimator, BLUE, whatever the variance components, so they are uniformly BLUE, UBLUE. From the results of the algebraic structure we will get explicit expressions for the LSE of these models.

Data size sufficiency analyses of haplotype inference algortihms

We present experimental and theoretical analyses of data requirements for haplotype inference algorithms. Our experiments include a broad range of problem sizes under two standard models of tree distribution and were designed to yield statistically robust results despite the size of the sample space. Our results validate Gusfield's conjecture that a population size of n log n is required to give (with high probability) sufficient information to deduce the n haplotypes and their complete evolutionary history. The experimental results inspired our experimental finding with theoretical bounds on the population size. We also analyze the population size required to deduce some fixed fraction of the evolutionary history of a set of n haplotypes and establish linear bounds on the required sample size. These linear bounds are also shown theoretically.

Business-science research collaboration under moral hazard

I analyze, in the context of business and science research collaboration, how the characteristics of partnership agreements are the result of an optimal contract between partners. The final outcome depends on the structure governing the partnership, and on the informational problems towards the efforts involved. The positive effect that the effort of each party has on the success of the other party, makes collaboration a preferred solution. Divergence in research goals may, however, create conflicts between partners. This paper shows how two different structures of partnership governance (a centralized, and a decentralized ones) may optimally use the type of project to motivate the supply of non-contractible efforts. Decentralized structure, however, always choose a project closer to its own preferences. Incentives may also come from monetary transfers, either from partners sharing each other benefits, or from public funds. I derive conditions under which public interventio

Restriction site-associated DNA sequencing, genotyping error estimation and de novo assembly optimization for population genetic inference.

Restriction site-associated DNA sequencing (RADseq) provides researchers with the ability to record genetic polymorphism across thousands of loci for nonmodel organisms, potentially revolutionizing the field of molecular ecology. However, as with other genotyping methods, RADseq is prone to a number of sources of error that may have consequential effects for population genetic inferences, and these have received only limited attention in terms of the estimation and reporting of genotyping error rates. Here we use individual sample replicates, under the expectation of identical genotypes, to quantify genotyping error in the absence of a reference genome. We then use sample replicates to (i) optimize de novo assembly parameters within the program Stacks, by minimizing error and maximizing the retrieval of informative loci; and (ii) quantify error rates for loci, alleles and single-nucleotide polymorphisms. As an empirical example, we use a double-digest RAD data set of a nonmodel plant species, Berberis alpina, collected from high-altitude mountains in Mexico.

Raising the Level of Moral Thinking among Managers Will Not Help. Kohlberg's Conventionality and Systemic Ethical Flaws in Business

Business ethicists often assume that unethical behavior arises when individuals deviate from the norms and responsibilities that are institutionalized to frame economic activities. People's greed motivates them to violate the rules of the game. In Kohlberg's terms, it is assumed that such actors make decisions in a preconventional way and act opportunistically. In this article, we propose an alternative interpretation of deviant behavior, arguing that such behavior does not result from a lack of conventional moral guidance but rather from the fact that characteristics attributed to preconventional morality by Kohlberg - the purely incentive and punishment driven opportunistic morality - have become the conventionalized morality. The prevailing norms that economic actors have internalized as their yardstick are those of the preconventional Homo economicus. Not the deviation from, but the compliance with the rules of the game explains many forms of harmful and illegal decisions made in corporations.

Bayesian Inference in the Time Varying Cointegration Model

There are both theoretical and empirical reasons for believing that the parameters of macroeconomic models may vary over time. However, work with time-varying parameter models has largely involved Vector autoregressions (VARs), ignoring cointegration. This is despite the fact that cointegration plays an important role in informing macroeconomists on a range of issues. In this paper we develop time varying parameter models which permit cointegration. Time-varying parameter VARs (TVP-VARs) typically use state space representations to model the evolution of parameters. In this paper, we show that it is not sensible to use straightforward extensions of TVP-VARs when allowing for cointegration. Instead we develop a specification which allows for the cointegrating space to evolve over time in a manner comparable to the random walk variation used with TVP-VARs. The properties of our approach are investigated before developing a method of posterior simulation. We use our methods in an empirical investigation involving a permanent/transitory variance decomposition for inflation.

Moral Hazard with Counterfeit Signals

In many moral hazard problems, the principal evaluates the agent's performance based on signals which the agent may suppress and replace with counterfeits. This form of fraud may affect the design of optimal contracts drastically, leading to complete market failure in extreme cases. I show that in optimal contracts, the principal deters all fraud, and does so by two complementary mechanisms. First, the principal punishes signals that are suspicious, i.e. appear counterfeit. Second, the principal is lenient on bad signals that the agent could suppress, but does not.
