This contribution compares existing and newly developed techniques for geometrically representing mean-variances-kewness portfolio frontiers based on the rather widely adapted methodology of polynomial goal programming (PGP) on the one hand and the more recent approach based on the shortage function on the other hand. Moreover, we explain the working of these different methodologies in detail and provide graphical illustrations. Inspired by these illustrations, we prove a generalization of the well-known two fund separation theorem from traditionalmean-variance portfolio theory.

Aims Food-deceptive pollination, in which plants do not offer any food reward to their pollinators, is common within the Orchidaceae. As food-deceptive orchids are poorer competitors for pollinator visitation than rewarding orchids, their occurrence in a given habitat may be more constrained than that of rewarding orchids. In particular, the success of deceptive orchids strongly relies on several biotic factors such as interactions with co-flowering rewarding species and pollinators, which may vary with altitude and over time. Our study compares generalized food-deceptive (i.e. excluding sexually deceptive) and rewarding orchids to test whether (i) deceptive orchids flower earlier compared to their rewarding counterparts and whether (ii) the relative occurrence of deceptive orchids decreases with increasing altitude. Methods To compare the flowering phenology of rewarding and deceptive orchids, we analysed data compiled from the literature at the species level over the occidental Palaearctic area. Since flowering phenology can be constrained by the latitudinal distribution of the species and by their phylogenetic relationships, we accounted for these factors in our analysis. To compare the altitudinal distribution of rewarding and deceptive orchids, we used field observations made over the entire Swiss territory and over two Swiss mountain ranges. Important Findings We found that deceptive orchid species start flowering earlier than rewarding orchids do, which is in accordance with the hypotheses of exploitation of naive pollinators and/or avoidance of competition with rewarding co-occurring species. Also, the relative frequency of deceptive orchids decreases with altitude, suggesting that deception may be less profitable at high compared to low altitude.

This paper presents a first approach of Evaluation Engine Architecture (EEA) as proposal to support adaptive integral assessment, in the context of a virtual learning environment. The goal of our research is design an evaluation engine tool to assist in the whole assessment process within the A2UN@ project, linking that tool with the other key elements of a learning design (learning task, learning resources and learning support). The teachers would define the relation between knowledge, competencies, activities, resources and type of assessment. Providing this relation is possible obtain more accurate estimations of student's knowledge for adaptive evaluations and future recommendations. The process is supported by usage of educational standards and specifications and for an integral user modelling

Este trabalho faz uma reflexão entre a percepção do cuidar pelo profissional de enfermagem e a relação do significado dado ao termo Cuidar, que é um instrumento norteador da qualidade da assistência. Questiona o nível de profundidade do significado que essa palavra pode assumir, identificando sua presença em todos os processos do Universo e na história mitológica do ser humano. Propõe que o cuidar é a Lei que permite a manifestação dos potenciais de organização numa certa direção de estabilidade dinâmica, manifestos na matéria, até a promoção e estabelecimento da saúde e do bem-estar. Concluiu-se, afirmando que a Lei do Cuidar pode ser entendida como um conjunto de forças que permitem o prolongamento ou abreviamento de certo grau de organização, que pode ser expresso em diversos níveis.

Models of codon evolution have attracted particular interest because of their unique capabilities to detect selection forces and their high fit when applied to sequence evolution. We described here a novel approach for modeling codon evolution, which is based on Kronecker product of matrices. The 61 × 61 codon substitution rate matrix is created using Kronecker product of three 4 × 4 nucleotide substitution matrices, the equilibrium frequency of codons, and the selection rate parameter. The entities of the nucleotide substitution matrices and selection rate are considered as parameters of the model, which are optimized by maximum likelihood. Our fully mechanistic model allows the instantaneous substitution matrix between codons to be fully estimated with only 19 parameters instead of 3,721, by using the biological interdependence existing between positions within codons. We illustrate the properties of our models using computer simulations and assessed its relevance by comparing the AICc measures of our model and other models of codon evolution on simulations and a large range of empirical data sets. We show that our model fits most biological data better compared with the current codon models. Furthermore, the parameters in our model can be interpreted in a similar way as the exchangeability rates found in empirical codon models.

O Brasil, até o ano de 2025, será o sexto país do mundo em número de idosos. É função das políticas públicas contribuir para que as pessoas alcancem idades avançadas com melhor saúde. O objetivo deste estudo foi conhecer o que pensam os profissionais sobre necessidades de saúde e atenção integral. Os sujeitos foram dezessete, que compõem duas equipes do Programa Saúde da Família, no Município de Santos. A abordagem foi qualitativa, os discursos foram analisados a partir da Representação Social, referencial teórico do Discurso do Sujeito Coletivo. A análise revelou que os profissionais se esforçam para atender as necessidades de saúde dos idosos através de ações de prevenção e promoção da saúde. No entanto, suas necessidades sociais e psicológicas não estão sendo atendidas. Concluímos que os idosos necessitam de maior integralidade e agilidade no sistema de saúde, porque possuem dificuldades no acesso e deslocamento nos serviços de saúde.

A new graph-based construction of generalized low density codes (GLD-Tanner) with binary BCH constituents is described. The proposed family of GLD codes is optimal on block erasure channels and quasi-optimal on block fading channels. Optimality is considered in the outage probability sense. Aclassical GLD code for ergodic channels (e.g., the AWGN channel,the i.i.d. Rayleigh fading channel, and the i.i.d. binary erasure channel) is built by connecting bitnodes and subcode nodes via a unique random edge permutation. In the proposed construction of full-diversity GLD codes (referred to as root GLD), bitnodes are divided into 4 classes, subcodes are divided into 2 classes, and finally both sides of the Tanner graph are linked via 4 random edge permutations. The study focuses on non-ergodic channels with two states and can be easily extended to channels with 3 states or more.

A Fibrose Cística é uma doença crônica que grande impacto exerce sobre a vida familiar. A experiência da doença é a maneira pela qual os indivíduos respondem à doença, atribuindo significados e buscando maneiras para lidar com ela no seu cotidiano. O estudo teve como objetivo compreender a experiência da Fibrose Cística a partir do contexto familiar. Estudo de caso etnográfico, realizado com famílias de crianças com a doença atendidas em um hospital escola do interior do estado de São Paulo. Os resultados foram divididos nos temas: passado, presente e futuro e permearam essas fases a busca pelo significado da doença e pelo suporte social, a importância da religião e espiritualidade e a centralidade da socialização da criança. Conhecer a experiência na doença e a rede social torna-se imprescindível para o planejamento de um cuidado integral. Essa abordagem mostrou-se inovadora para o cuidado à doença crônica.

An important statistical development of the last 30 years has been the advance in regression analysis provided by generalized linear models (GLMs) and generalized additive models (GAMs). Here we introduce a series of papers prepared within the framework of an international workshop entitled: Advances in GLMs/GAMs modeling: from species distribution to environmental management, held in Riederalp, Switzerland, 6-11 August 2001.We first discuss some general uses of statistical models in ecology, as well as provide a short review of several key examples of the use of GLMs and GAMs in ecological modeling efforts. We next present an overview of GLMs and GAMs, and discuss some of their related statistics used for predictor selection, model diagnostics, and evaluation. Included is a discussion of several new approaches applicable to GLMs and GAMs, such as ridge regression, an alternative to stepwise selection of predictors, and methods for the identification of interactions by a combined use of regression trees and several other approaches. We close with an overview of the papers and how we feel they advance our understanding of their application to ecological modeling.
