was employed the applied research, and as for the approaching method it was used the quantitative research.
The operationalization instruments of information collected were multiple correspondence analysis, internal
consistency determination and the means and standard deviations calculation.
The study of data obtained, for answering the hypothesis raised in this investigation, allowed, in a general
perspective, to characterize the safety climate of hotel establishments in Alentejo Litoral as positive and
tendentiously strong
Does work per repetition and phase angle play a role in Sarcopenia?
Aging is related to the increase of several
chronic diseases, such as, osteoarthritis, osteoporosis, diabetes,
hypertension and sarcopenia. Sarcopenia (progressive loss of
muscle mass and physical performance) is related to difficulties
in treating other comorbidities, whether pharmacologically
or non-pharmacologically.info:eu-repo/semantics/publishedVersio
Phase angle in osteoarthritis patients, relations with pain, muscular mass and strength
Several researches have been carried out to see the relation
between the Phase Angle (PhA), disease and several health risks factors.
Ageing is associated with the loss of muscle mass and changes in body
composition, which result in a decrease of the PhA. Malnutrition and
inflammation have been reported to have a strong influence on PhA in
diseased individuals. Subjects with Osteoarthritis (OA) have decreased
muscular strength and pain. The aim of this study was to understand if
the PhA was altered in patients with OA and if it's related with pain,
muscular mass and strength.info:eu-repo/semantics/publishedVersio
Performative Poetry as Program, Programmed Poetry as Performance
UIDB/05021/2020
UIDP/05021/2020Innovative forms of poetry such as language art and experimental poetry have adopted intersemiotic processes and linguistic constraints in their codification, promoting rereading and transgression of technical apparatuses from the techno-capitalist societies. In addition, new inventive forms of digital language art, such as electronic poetry, have integrated generativity, indeterminacy and combinatorics in their programming, stimulating the reinvention and subversion of computing mechanisms from the networked societies. Through the appropriation of media, poetry articulates creative strategies that question the interface between arts and languages, forms and mechanisms. The experimental attitude of performative poetry presents itself as a program. Similarly, using the potentialities of the computer as a semiotic machine, programmed poetry can be regarded as performative, producing unique, unrepeatable events. Poetry and performance can thus be regarded as floating entities, promoting the transition from a fixed order to an economy of circulations. This scenario fuels the discussion concerning the connections between poetry, performance and program, supporting our reflections through the presentation and description of different examples of poetic intervention in the Portuguese context, which use programming and coding to reconfigure the awareness of language and mediation.publishersversionpublishe

Ontogenia e estrutura do pericarpo e do envoltório da semente de Miconia albicans (Sw.) Triana (Melastomataceae) do cerrado, Brasil
Miconia albicans fruit and seed coat ontogeny were described under light microscope. The samples were fixed in formalin-aceto-alcohol (FAA), neutral-buffered formaldehyde solution (NBF) and formalin-ferrous sulphate (FFS) solutions, embedded in plastic resin, sectioned at 10 µm and stained with Toluidine Blue. Specific dyes and/or reagents were used for the microchemical tests. The ovary is semi-inferior and the indehiscent, fleshy globose berries are originated mainly from the development of the inferior portion of the ovary. The immature pericarp is mainly parenchymatous with some sclereids, druse crystal and phenolic-like compounds idioblasts widespread in the mesocarp. In the mature pericarp, the endocarp cells are often collapsed, the mesocarp is thick with cells more or less turgid, and the sclereids, the druses and the phenolic-like compound idioblasts are almost absent. The ovules are anatropous, bitegmic and crassinucellate, and the zig-zag micropyle is formed by both the exostome and the endostome. The mature seed is pyramidal-elongated in shape, exalbuminous and testal. The raphal part occupies about 40% of the seed coat total length and had the mechanical layer derived from its inner layer. The antiraphal side is non-multiplicative and the exotesta, mesotesta and endotesta are differentiated into a sclerotic layer, with the exotesta being the mechanical one. The tegmen is absent.A ontogenia dos frutos e das sementes de M. albicans foi descrita sob microscopia de luz. Os materiais foram fixados em soluções de formalina - ácido acético - álcool etílico 50% (FAA), formalina neutra tamponada (FNT) e sulfato ferroso em formalina (SFF), embebidos em resina plástica, seccionados a 10 µm de espessura e corados com Azul de Toluidina. Corantes e/ou reagentes específicos foram usados para os testes microquímicos. O ovário é semi-ínfero, e os frutos são bagas indeiscentes, originadas em sua maior parte a partir do desenvolvimento da porção ínfera do ovário. O pericarpo imaturo é principalmente parenquimático, com esclereídes, idioblastos cristalíferos e com compostos fenólicos no mesocarpo. No pericarpo maduro as células do endocarpo estão freqüentemente colapsadas, o mesocarpo é espesso, com células túrgidas, e as esclereídes e os idioblastos cristalíferos e com compostos fenólicos estão em pequena quantidade. Os óvulos são anátropos, bitegumentados e crassinucelados, e a micrópica, em zig-zag, é formada pelo exóstoma e pelo endóstoma. A semente madura é piramidal-alongada, exalbuminosa e testal. A porção rafeal ocupa aproximadamente 40% do comprimento total da semente e possui a camada mecânica derivada de suas camadas internas. A porção anti-rafeal é não-multiplicativa e possui a exotesta, a mesotesta e a endotesta diferenciadas em camada mecânica (esclerótica). O tégmen é ausente.717
A dependence modelling study of extreme rainfall in Madeira Island
The dependence between variables plays a central role in multivariate extremes. In this paper, spatial dependence of Madeira Island's rainfall data is addressed within an extreme value copula approach through an analysis of maximum annual data. The impact of altitude, slope orientation, distance between rain gauge stations and distance from the stations to the sea are investigated for two different periods of time. The results obtained highlight the influence of the island's complex topography on the spatial distribution of extreme rainfall in Madeira Island.The authors wish to thank the Portuguese Foundation for Science

Processo de mudança na terapia para as fobias de afetos na perspetiva do cliente: um estudo qualitativo
A pertinência do estudo da perspetiva do cliente é cada vez mais reconhecida
como um meio de compreensão do modo como a psicoterapia funciona e de validação
dos modelos terapêuticos. A mudança através do Modelo para o Tratamento das Fobias
de Afetos (MTFA) ocorre quando os clientes aprendem a reconhecer e a comunicar as
suas emoções – fator fundamental para que haja saúde mental. Contudo, as pesquisas
sobre os mecanismos envolvidos no processo de mudança desta terapia são ainda muito
escassas. Nesse sentido, pretendemos identificar qual a perspetiva dos clientes acerca do
seu processo de mudança pelo MTFA. Para o efeito, foram realizadas entrevistas
semiestruturadas a oito clientes que concluíram um processo terapêutico. A análise das
entrevistas foi realizada através de uma abordagem qualitativa, com base na Análise
Temática, recorrendo ao software nVivo. Foram identificados dois temas, 10 categorias
e 14 subcategorias. De forma geral, observa-se que os participantes atribuem a sua
mudança a ganhos ao nível da compreensão, expressão e equilíbrio das suas emoções. Ao
longo do processo, são referidos aspetos importantes como a proximidade terapêutica e
experiência de libertação emocional. Os resultados são consistentes com os estudos
qualitativos anteriores e com os estudos sobre o MTFA. As principais descobertas são
discutidas com base na literatura atual sobre o processo de mudança em psicoterapia de
acordo com a perspetiva dos clientes.The relevance of studying the client's perspective is increasingly recognized as a
mean of comprehending how psychotherapy works and how it validates therapeutic
models. Change through the Model for the Treatment of Affect Phobia (APT) occurs
when clients learn to recognize and communicate their emotions – a fundamental factor
for a good mental health. However, research on the mechanisms involved in the change
process of this therapy is still very scarce. To clarify this, we intend to identify the client's
perspective on their process of change by the APT. For this purpose, semi-structured
interviews were carried out with eight clients, who had completed the therapeutic process.
The analysis of the interviews was carried out through a qualitative approach, based on
Thematic Analysis, using the nVivo software. Two themes, 10 categories and 14
subcategories were identified. In general, is observed that the participants attribute their
process of change to gains in comprehension, expression, and balance of their emotions.
Throughout the process important aspects were mentioned, such as therapeutic proximity
and the experience of emotional release. The results are consistent with previous
qualitative studies, and studies on the APT. The main results are discussed based on the
current literature on the process of change in psychotherapy through the perspective of
clients
Resenha de Robert Rowland Smith. On Modern Poetry – From Theory to Total Criticism. London; New York: Continuum, 2012, 182 págs. ISBN 9781441174222
Ilustración: "Lectura poetica en Bukowski Club (Madrid)", pepeltensoOn Modern Poetry – From Theory to Total Criticism, de Robert Rowland Smith, constitui um manifesto teórico no panorama da crítica literária do séc. XX e XXI. O filósofo e autor de Breakfast with Socrates (2009) propõe, no seu mais recente livro, uma teoria radical de análise poética a que dá o nome de Criticismo Total, defendendo o regresso dos estudos literários ao texto. Identificando na poesia europeia recente uma “identidade moderna”, este trabalho aponta as insuficiências metodológicas do Criticismo
Prático e da Teoria, propondo um novo método de “close reading” e abordagem analítica àquela identidade
Um buraco no ovo: Problemáticas da linguagem em António Aragão
António Aragão é uma das figuras mais icónicas do experimentalismo português.
A sua pesquisa literária encontra-se intimamente ligada à natureza da linguagem e dos seus procedimentos de pesquisa. A obra “Povo/Ovo” (1977) é paradigmática neste contexto, apenas se conhecendo, no entanto, hoje, parte da sua história. Neste artigo ensaiam-se possíveis caminhos de entrada e saída para este episódio da literatura experimental, ao mesmo tempo que se reflete sobre os contributos deste autor para uma
teorização experimental da linguagem
