Abstract:

O presente artigo apresenta a proposição de uma abordagem robusta para a modelagem da satisfação de clientes de serviços. A abordagem robusta representa uma extensão da abordagem proposta por Tinoco e Ribeiro (2007), através da inclusão de estatísticas robustas que podem representar adequadamente as relações causais que envolvem a satisfação de clientes de serviços, mesmo na presença de respondentes inconsistentes. Os procedimentos robustos permitem identificar esses respondentes inconsistentes e atribuir uma ponderação em função da concordância de cada questionário em relação ao conjunto das observações. A modelagem proposta é apresentada e testada através da construção de um modelo geral de satisfação de clientes de serviços. Para isso, foram avaliados 12 segmentos de serviços escolhidos para o estudo por contemplarem diferentes categorias de serviços, no que se relaciona a grau tangibilidade e grau de contato e de envolvimento do cliente. A abordagem robusta permitiu confirmar a maioria das relações significativas entre determinantes da satisfação obtidas a partir da abordagem tradicional proposta por Tinoco e Ribeiro (2007) e, além disso, incorporar ao modelo outra relação significativa que não seria considerada a partir da técnica tradicional.

Abstract:

En este trabajo se compara la regresión de Gini con la regresión OLS y otros métodos de regresión robustos, del tipo L (LAV, combinaciones lineales de estadísticos de orden), del tipo M (M de Huber, basado en el concepto de máxima verosimilitud) y del tipo MM (basado en la minimización de un estimador M). La comparación de los métodos se realiza vía simulación bajo diferentes escenarios. Los resultados encontrados vía simulación muestran que la regresión de Gini tiene un mayor grado de robustez en comparación con la regresíon OLS al estimar los coeficientes de regresión ante la presencia de datos atípicos, pero su robustez es menor que la de los métodos de estimación robustos LAV, M de Huber y MM

Abstract:

El objetivo de este trabajo es explorar cuáles serían las circunstancias políticas que llevan a las autoridades de gobierno a impulsar y desarrollar estrategias relativamente robustas de Datos Abiertos Gubernamentales (DAG), a pesar de que ello implicaría debilitar su posición de poder y entregar parte del control sobre la información pública a la ciudadanía, el Congreso y otros actores. Para ello, se estudian los casos de México, Chile y Colombia entre 2010 y 2018, países en que se han implementado políticas de DAG con diferentes grados de éxito. La información proporcionada por diversos entrevistados, en conjunto con el análisis de información secundaria, muestra que (1) la robustez de la estrategia de DAG de México debe bastante a los casos de corrupción en que se vieron envueltos directamente el presidente Peña Nieto y su señora; (2) la debilidad de la política de DAG chilena es coherente con un grado generalizado de desinterés por esta tecnología entre las autoridades gubernamentales; y (3) la robusta y gradual evolución de la estrategia de DAG en Colombia tiene como antecedente indirecto la intención del presidente Santos de mejorar la imagen internacional del país.

Abstract:

Atualmente, a necessidade de coordenadas confiáveis tem sido um dos objetivos da comunidade científica e prática. Desta forma, a análise de robustez de uma rede geodésica, tem como objetivos, com base nos erros máximos não detectados, analisar se a rede é "robusta" ou não. A rede será robusta se a influência destes erros for pequena, caso contrário é "fraca", ou seja, "não robusta". Esta análise se faz com a fusão de duas técnicas, uma que trata da análise estatística de confiabilidade e outra sobre a análise geométrica de deformações. A análise de confiabilidade fornecerá o erro máximo que não pode ser detectado por testes, após o ajustamento. Depois de encontrar estes erros, a análise geométrica de deformações determinará o potencial de deformação que esta rede terá com base nestes erros. Ressalta-se, ainda, que a análise de robustez não é dependente de datum, refletindo somente na geometria da rede e na acurácia das observações (VANÌCEK et al., 2001). Portanto, este trabalho tem como propósito contribuir com as investigações científicas sobre redes geodésicas, checando a mesma, com base em sua geometria e observações.

Abstract:

Abstract The validity of the Alchian–Allen (AA) theorem is tested for the export demand of Brazilian Arabica (high-quality) and Robusta (low-quality) coffees. We check for robustness using different model specifications, estimation procedures and time periods. Given that international prices for both Brazilian naturals (Arabica varieties) and Robusta are determined on international commodity exchanges, the change in relative price varies by country only due to changes in transportation costs. Results show that the consumption of Arabica increases relative to the consumption of Robusta with distance, therefore with the corresponding increasing per-unit transportation cost. We confirm that GDP per capita does not impact relative demand for coffee.

Die Gewöhnliche Robinie oder Falsche Akazie (Robinia pseudoacacia) ist Deutschlands Baum des Jahres 2020. Sie stammt aus Nord-Amerika, ist aber weltweit vielerorts eingebürgert. Sie liefert robustes Holz und ist eine gute Bienenweide. Als hitze- und trockenheitsresistente robuste Art könnte sie ein sogenannter Klimawandelbaum für die Zukunft sein. Die Robinie ist aber auch ein invasiver Neophyt, der vor allem an mageren Standorten die heimische Vegetation verdrängen kann.

Full text

Abstract:

Streptostachys robusta was described from a single collection from Southern Bahia, Brazil. Because of the early flowering stage of the type material, with immature spikelets, the taxonomic position of this species remained uncertain for more than three decades. We obtained new collections of the taxon, and using several lines of evidence demonstrate that S. robusta belongs to the genus Ichnanthus and is related to I. bambusiflorus. We transfer this species to Ichnanthus, as I. robustus, and amend its description to reflect a broader range of morphological variation, based on study of all known specimens. Details of fully developed spikelets are presented for the first time. We also propose an epitype for the name S. robusta because the holotype and isotypes do not allow precise application of the name.

Abstract:

É apresentada uma abordagem computacional baseada em otimização para o projeto de controladores de ordem fixa através de alocação robusta de pólos para plantas lineares e invariantes no tempo, SISO, com incertezas do tipo intervalar. O objetivo do projeto é a minimização do desvio total do desempenho desejado para o sistema em malha fechada, especificado por um politopo de polinômios característicos. O problema de projeto por alocação robusta de pólos é associado à solução de uma equação Diofantina intervalar, cujas propriedades básicas são analisadas. Controladores por alocação robusta de pólos são vistos como soluções internas da equação Diofantina intervalar. Caracterizações simples e computacionalmente eficientes do conjunto de todos os controladores por alocação robusta de pólos são então obtidos e algumas das suas propriedades geométricas discutidas. Vários aspectos do projeto de controladores robustos por Análise Intervalar são integrados a uma formulação de programação alvo linear, que também pode incorporar restrições adicionais aos parâmetros do controlador. Exemplos ilustram as principais características da abordagem proposta.

Abstract:

O artigo tem como objetivo principal apresentar uma metodologia simples para estimar o grau de cobertura dos registros de óbitos e obter estimativas de mortalidade para pequenas áreas, usando Minas Gerais como exemplo. A metodologia proposta combina a padronização indireta da estrutura de mortalidade de áreas menores com base nas funções de mortalidade de áreas maiores, e depois a aplicação dos métodos de distribuição de mortes para obter estimativas mais robustas de mortalidade para áreas menores. Os resultados obtidos são robustos e adequados quando comparados com estimativas oficiais e usando outros métodos. As estimativas em dois estágios foram tão robustas que elas reduziram o sobre-registro de óbitos em alguns casos e melhorou as estimativas de mortalidade adulta em algumas áreas onde os dados são menos confiáveis.

Abstract:

Unter den Bedingungen eines volatilen Umfelds wird es für Unternehmen heute schwieriger die Zielerreichung in der Produktion sicherzustellen. Heterogene Schwankungen im Verhalten der Elemente eines Produktionssystems erfordern die Fähigkeit, Planzustände stabil beibehalten zu können. Dieser Beitrag stellt einen Messansatz vor, der mithilfe der Materialflusssimulation diese Elemente einer Produktion hinsichtlich ihrer Robustheit bewertet. So lassen sich robuste Produktionssysteme ableiten.   It is becoming increasingly difficult for manufacturing companies to achieve their production targets in today’s volatile economic environment. Heterogeneous fluctuations in the behaviour of components of a manufacturing system require stable planning states. The following article presents a measurement approach which uses material flow simulation to evaluate components in manufacturing in terms of their robustness. Thus, robust manufacturing systems can be derived.

Abstract:

Shorea robusta is a valuable tree species which provides good quality timber along with other useful materials like seeds which can be used as a source of starch. Woody plants are difficult to regenerate under in vitro conditions and only some success has been achieved so far. Here we have presented the data for successful in vitro regeneration of S. robusta using nodal explants. Shoot proliferation and rooting were also successfully achieved in subsequent subcultures. The best medium for shoot initiation and proliferation was found to be WPM with 1.0 mg·l<sup>–1</sup> BAP and 0.5 mg·l<sup>–1</sup> NAA and 1.0 mg·l<sup>–1</sup> BAP +0.5 mg·l<sup>–1</sup> NAA, respectively. Likewise for rooting WPM medium with 0.5 mg·l<sup>–1</sup> IBA was found to be the best medium.

Abstract:

The <I>in vitro</I> radical scavenging capacity of the roasted and ground coffee is generally known as well as the published results of lowering the incidence of various diseases by regular intake of coffee. The antioxidant capacity of coffee is based mainly on the phenols, but during the roasting phenols are degraded and new products with antioxidant capacity are formed. A major contributor to the antioxidant activity was identified as N-methylpyridinium, which is formed during the roasting by degradation of trigonelline, the degradation is about 50% of trigonelline content and the concentration of N-methylpyridinium in roasted coffee is up to 0.25% on a dry weight basis. These literature data were verified within the processing plant experiment, during the usual roasting procedure of Robusta coffee the following parameters were analysed: humidity, water activity, total antioxidant capacity, total phenols, chlorogenic acid and trigonelline content, and colour <I>(L*, a*, b*</I>). The changes of the evaluated parameters were correlated to each other. During the roasting the total antioxidant capacity (TAC) decreased to about one half of original level in the beginning stages of roasting, another decrease continued during the storage of roasted coffee at about 10% within the year. The degradation of trigonelline, neither the content of chlorogenic acid or total phenols did not correlate with TAC in samples during the roasting and storage.

Abstract:

L’objectif de cet article est de définir et illustrer la notion de robustesse telle qu’elle est vue par les généticiens. Pour ces derniers, il existe deux concepts de robustesse. Le premier considère que la robustesse correspond à la capacité de survie de l’animal et au maintien d’un potentiel global de production dans des environnements stressants et fait notamment référence au rôle de l’axe corticotrope. Le second concept définit la robustesse comme le maintien d’un potentiel de production spécifique : dans ce cadre, un animal est dit robuste pour un caractère donné si ce caractère est stable dans des environnements variés, ce qui rejoint la notion d’interaction génotype-milieu et s’explique par différentes hypothèses génétiques (modèle de surdominance, modèle pléiotropique, modèle épistatique). La canalisation d’un caractère correspond alors à l’action de sélectionner pour diminuer la sensibilité aux variations environnementales. Cette canalisation est intéressante pour répondre, par exemple, aux attentes des producteurs (optimum de production), des transformateurs (homogénéité des productions) ou aux nouvelles contraintes environnementales (agriculture durable). La mise en pratique de cette dernière passe par différentes modélisations des interactions génotype-milieu ; la plus novatrice utilise les modèles dits structuraux qui considèrent une variabilité génétique de la variance du caractère considéré et pour lesquels des développements méthodologiques sont encore nécessaires. Différentes expériences de sélection canalisante ont été mises en place sur des animaux de rente avec plus ou moins de succès. A l’heure actuelle, seule la sélection canalisante sur l’homogénéité des poids des lapereaux à la naissance est pratiquée en routine.
