Aplicação de cartas de controlo na monitorização de resultados de ensaios de comparação interlaboratorial

A norma NP EN ISO/IEC 17025 descreve os requisitos gerais para o reconhecimento da competência de um laboratório em realizar ensaios e/ou calibrações, incluindo amostragem, que é utilizada pelos laboratórios para desenvolver os seus sistemas de gestão da qualidade e para as atividades administrativas e técnicas. Além da referência aos procedimentos de controlo da qualidade para monitorizar a validade dos ensaios e calibrações realizadas, é referida a necessidade dos laboratórios participarem em Ensaios de Comparação Interlaboratorial (ECI) como garantia da fiabilidade dos resultados. Neste trabalho, apresentam-se resultados da aplicação de cartas de controlo de qualidade para monitorização da estatística z-score (diferença entre o resultado obtido pelo laboratório participante e o valor de referência dividida pelo erro). Quando os dados analisados apresentam autocorrelação, é testado um modelo apropriado de série temporal, ou seja, um modelo que remova a autocorrelação dos dados aplicando cartas de controlo aos resíduos

ELEMENTOS DE CARTOGRAFÍA MATEMÁTICA Y SU APLICACIÓN EN LA ELABORACIÓN DE LAS CARTAS GEOGRÁFICAS

En este artículo se analizan algunos de los elementos básicos de la cartografía matemática, partiendo de los aspectos generales como sistemas de coordenadas y superficies de referencia. Se discuten además los elementos cartográficos sobre los esferoides, los datums y la definición de los sistemas de coordenadas geográficas, así como las transformaciones esferoidales. Una vez establecidos los conceptos básicos, se discuten los aspectos fundamentales de la teoría de las proyecciones cartográficas y sus principales características.ABSTRACTThis article analyzes some basic concepts about mathematical cartography, from general aspects such as coordinate systems and reference surfaces. The cartographic elements concerning spheroids, datum and definitions of geographical coordinate systems are discussed, as well as the spheroid transformations. Based on these basic concepts, the fundamental aspects of cartographic projections theory and its main characteristics are discussed.

THE “CARTAS PORTUGUESAS” (PORTUGUESE LETTERS) AND THE TRADITION OF THE “UNREQUITED LOVE" IN THE PORTUGUESE LITERATURE OF FEMALE VOICE

Inserted in the perspective of literary studies, this paper proposes an analysis of the “Cartas Portuguesas” (Portuguese Letters), a work attributed to Mariana Alcoforado, assuming that this work is constituted within the Lusitanian literature as an important formative element of the imaginary loving Portuguese female voice. Through the study, it is possible to identify the fact that the letters are prefaced, stylistically or thematically, by the songs of love and of friend, and succeeded by works such as “Livro de Sóror Saudade” (Book of Longing Sóror), of Florbela Espanca, and “Novas Cartas Portuguesas” (New Portuguese Letters) by Maria Isabel Barreno, Maria Velho da Costa and Maria Teresa Horta.

Physical activity in Latino men and women: Facilitators, barriers, and interventions

Latinos report less leisure time physical activity (PA) than non–Latino Whites and suffer disproportionately from diseases related to sedentary lifestyle, yet remain underserved and understudied. Gaining a better understanding of PA behavior in Latinos is critical to intervene on this significant public health issue. This article discusses the growing literature on the facilitators and barriers of PA in Latino men and women and reviews recent interventions to promote activity. Apart from acculturation influences, facilitators of PA in Latinos are similar to those of non–Latino Whites, with most research focusing on self-efficacy and social support. Barriers for Latinas, however, are more culturally distinct, such as a focus on caregiving and cultural standards for body shape. Barriers unique to Latino men largely have not been studied. Researchers have adopted a variety of approaches to increase PA, including using promotores and incorporating culturally appropriate activities, and have had mixed success. However, the community and randomized controlled trials almost exclusively included only women. Studies reviewed here suggest that interventions should target culturally specific barriers beyond language to successfully increase PA in Latinos and highlight a need for formative research and design of interventions for Latino men.

Awareness and knowledge of Human Papillomavirus (HPV) among ethnically diverse women varying in generation status

Although Human papillomavirus (HPV) is a common sexually transmitted infection, there is limited knowledge of HPV with ethnic/racial minorities experiencing the greatest disparities. This cross-sectional study used the most recent available data from the California Health Interview Survey to assess disparities in awareness and knowledge of HPV among ethnically/racially diverse women varying in generation status (N = 19,928). Generation status emerged as a significant predictor of HPV awareness across ethnic/racial groups, with 1st generation Asian-Americans and 1st and 2nd generation Latinas reporting the least awareness when compared to same-generation White counterparts. Also, generation status was a significant predictor of HPV knowledge, but only for Asian-Americans. Regardless of ethnicity/race, 1st generation women reported lowest HPV knowledge when compared to 2nd and 3rd generation women. These findings underscore the importance of looking at differences within and across ethnic/racial groups to identify subgroups at greatest risk for poor health outcomes. In particular, we found generation status to be an important yet often overlooked factor in the identification of health disparities.

El escrito autobiográfico de Fernando Álvarez de Albornoz y la guerra civil castellana (1366- 1371)

Resumen: En la segunda mitad del siglo XIV, Fernando Álvarez de Albornoz escribió un texto autobiográfi co en latín en la hoja de guarda de un códice del Decreto de Graciano. Parte de este texto es un relato de la guerra civil castellana (1366-1371), probablemente basado en la información que le llegó a Italia a través de cartas enviadas a él o a alguno de sus familiares. Así, puede ser estudiado como fuente primaria o como escrito historiográfi co. En este estudio el texto es transcrito, traducido y analizado. A partir de este análisis, se proponen una datación del texto, modelos para sus estructuras temática y narrativa, y algunas hipótesis sobre su naturaleza e intencionalidad.

Proto-alphabetic inscriptions from the Wadi Arabah

Abstract: Three early West Semitic inscriptions from the Arabah valley are studied here, all of them apparently connected with the Egyptian copper-mining activity in the region, notably at Timna, in the period of the Ramessides. The most striking detail in these texts is a sign corresponding to an Egyptian hieroglyph (N6B ) which depicts two serpents guarding the sun-disc, and another with one serpent (N6 , ); these never appear on conventional tables of early alphabetic letters; this leads to a critical reappraisal of current identifications of the original picture-signs, and elaboration of a new system of interpreting early Canaanite inscriptions, involving recognition that the signs could sometimes stand for whole words and could also be used as rebuses.
