- Desenvolvimento de habilidades socioprofissionais em indivíduos com necessidades especiais: avaliação de um programa de intervençãoPublication . Franco, Maria da Glória; Rodrigues, Ana Sofia; Rodrigues, Nuno; Telo, SimoneDe entre todas as transições pelas quais o ser humano passa ao longo da sua vida, a transição para a vida adulta (TVA) é uma das mais desafiantes, pois implica a entrada no mercado laboral, tarefa difícil para indivíduos com e sem incapacidade intelectual. Relativamente à procura do primeiro emprego, explorou-se as características mais valorizadas no mercado de trabalho e, entre outras, destacam-se as habilidades sociais e socioprofissionais. Torna-se, por isso, fundamental apostar em programas de desenvolvimento destas habilidades, de forma a preparar melhor as pessoas com incapacidade intelectual para os desafios da TVA. Assim sendo, contruiu-se e aplicou-se o programa de intervenção “Sou Capaz – Programa de Desenvolvimento de Habilidades Socioprofissionais”, avaliando-se se o mesmo promove o desenvolvimento de habilidades socioprofissionais em indivíduos com incapacidade intelectual, bem como se essas habilidades desenvolvidas se mantêm ao longo do tempo. Com uma amostra de 10 indivíduos institucionalizados, divididos em dois grupos homogéneos, as avaliações realizadas basearam-se na metodologia multiple probe design, aplicando-se uma forma adaptada do Inventário de Habilidades Sociais (IHS). Os resultados apontam para uma evolução após a intervenção no grupo dois. Contudo, registou-se alguma dificuldade em manter as aquisições ao longo do tempo. Em suma, é importante continuar a refletir sobre as temáticas abordadas, contribuindo para a consolidação e evolução dos conhecimentos científicos, assim como para uma profícua adaptação da intervenção às idiossincrasias dos indivíduos com necessidades especiais.
- A variação entre ter e haver em construções existenciais numa variedade insular do PE (Funchal)Publication . Bazenga, AlineA sintaxe do português, tal como outros domínios do seu sistema, mudou ao longo do tempo. No entanto, algumas variedades do português europeu (PE), sobretudo insulares, exibem traços sintáticos não-padrão mais conservadores, que resistiram à mudança ocorrida em variedades continentais, de que é exemplo o uso de ter em construções existenciais (onde eu trabalho tem muita gente de idade). O estudo que propomos, realizado no âmbito da Sociolinguística Variacionista (Weinreich, Labov e Herzog 1968, Labov 1972), visa analisar as ocorrências de ter e de haver neste tipo de construções em amostras do PE falado no Funchal (PEI-Funchal), selecionadas a partir do Corpus Concordância (Bazenga 2014). Os resultados apontam para valores significativos do uso da variante ter não-padrão – embora não tão expressivos quanto os observados em variedades do Português do Brasil (PB) (Mattos e Silva 2002a, 2002b, Avelar 2006a, 2006b) – como também para a influência de variáveis linguísticas (morfologia do verbo e traço semântico do N que integra o SN à sua direita) e sociais (género e nível de escolaridade dos falantes), em conformidade com o observado em trabalhos similares, realizados no âmbito das variedades do PB).
- Variation of carbon and isotope natural abundances (δ15N and δ13C) of whole-plant sweet potato (Ipomoea batatas L.) subjected to prolonged water stressPublication . Gouveia, Carla S.S.; Ganança, José F.T.; Slaski, Jan; Lebot, Vincent; Carvalho, Miguel Â. A.Sweet potato (Ipomoea batatas L.) is an important crop in the world, cultivated in temperate climates under low inputs. Drought changes the plant biomass allocation, together with the carbon and nitrogen isotopic composition (δ13C and δ15N), whose changes are faintly known in sweet potato crops. Here, we show the biomass allocation of eight sweet potato accessions submitted to drought during 3 months, using the δ13C, δ15N, carbon isotope discrimination (Δ13C), total carbon (TC) and water use efficiency (WUE) traits. The tolerant accessions had improved WUE, with higher TPB and TC. Storage roots and shoots had a heavier δ13C content under drought stress, with greater 13C fixation in roots. The Δ13C did not show a significant association with WUE. The δ15N values indicated a generalised N reallocation between whole-plant organs under drought, as a physiological integrator of response to environmental stress. This information can aid the selection of traits to be used in sweet potato breeding programs, to adapt this crop to climate change.
- Is it necessary to show virtual limbs in action observation neurorehabilitation systems?Publication . Modroño, Cristián; Bermúdez, Sergi; Cameirão, Mónica; Pereira, Fábio; Paulino, Teresa; Marcano, Francisco; Hernández-Martín, Estefanía; Plata-Bello, Julio; Palenzuela, Nereida; Núñez-Pádron, Daniel; Pérez-González, José M; González-Mora, José LAction observation neurorehabilitation systems are usually based on the observation of a virtual limb performing different kinds of actions. In this way, the activity in the frontoparietal Mirror Neuron System is enhanced, which can be helpful to rehabilitate stroke patients. However, the presence of limbs in such systems might not be necessary to produce mirror activity, for example, frontoparietal mirror activity can be produced just by the observation of virtual tool movements. The objective of this work was to explore to what point the presence of a virtual limb impacts the Mirror Neuron System activity in neurorehabilitation systems.
- Tourist events and satisfaction: a product of regional tourism competitivenessPublication . Teixeira, Sérgio; Ferreira, João J. M.; Almeida, António; Parra-Lopez, EduardoPurpose – This study aims to analyze the contribution of tourist event and satisfaction with tourism events as a product of regional tourism competitiveness, as well as evaluate factors of competitiveness. Design/methodology/approach – The research followed a quantitative methodology by conducting a questionnaire on the four largest tourist events in Madeira (Carnival, Flower Festival, Atlantic Festival and Wine Festival), an insular island located in Portugal. Findings – The sample consisted of 2,262 tourists surveyed during the year 2017 and structural equation models were used as the statistical method. Results showed that satisfaction is reflected in the client’s loyalty to the choice of a tourist destination and also contributes directly and indirectly to the regional tourist competitiveness. Originality/value – This study contributes to the valorization of local and regional events, perceived by the level of satisfaction and loyalty of tourists, as products of regional competitiveness of a tourist destination.
- Effects of hydroxycinnamic acids on the glycolysis pathwayPublication . Serina, J.; Fernandes, M. X.; Castilho, P. C.Glycolysis is a metabolic pathway vital to the production of energy and some organisms rely on it solely to meet their energy requirements. It is also a central pathway in the metabolism of carbohydrates and a source of therapeutic targets against diabetes and cancer. Caffeoylquinic acids (CQAs) have been extensively studied for their role in the treatment and prevention of diabetes (and cancer) but their mechanisms of action remain mostly unknown. As such, molecular docking was used to find possible targets of CQAs in the glycolysis pathway. The molecular docking assays showed that CQAs were docked preferably to the Rossman fold (nicotinamide adenine dinucleotide — NAD(H) binding site) of oxidoreductases, that use NAD(H) as a cofactor, than to any other site. In-vitro assays were then performed using two NAD(H) dependent oxidoreductases from glycolysis (alcohol dehydrogenase and L-lactate dehydrogenase) in order confirm if CQAs would compete with the cofactor to inhibit the reaction. The results from these assays indicate that CQAs can act as both inhibitors and activators of NAD(H) dependent oxidoreductases of the glycolysis pathway.
- The impact of perioperative data science in hospital knowledge managementPublication . Baptista, Márcia; Vasconcelos, José Braga; Rocha, Álvaro; Silva, Rita; Carvalho, João Vidal; Jardim, Helena Gonçalves; Quintal, AntónioConservative practices, such as manual registry have limited scope regarding preoperative, intraoperative and post operative decision making, knowledge discovery, analytical techniques and knowledge integration into patient care. To maximize quality and value, perioperative care is changing through new technological developments. In this context, knowledge management practices will enable future transformation and enhancements in healthcare services. By performing a data science and knowledge management research in the perioperative department at Hospital Dr. Nélio Mendonça between 2013 and 2015, this paper describes its principal results. This study showed perioperative decision-making improvement by integrating data science tools on the perioperative electronic system (PES). Before the PES implementation only 1,2% of the nurses registered the preoperative visit and after 87,6% registered it. Regarding the patient features it was possible to assess anxiety and pain levels. A future conceptual model for perioperative decision support systems grounded on data science should be considered as a knowledge management tool.
- Fish processing industry residues: a review of valuable products extraction and characterization methodsPublication . Ideia, Pedro; Pinto, Joana; Ferreira, Rui; Figueiredo, Leandro; Spínola, Vítor; Castilho, Paula C.Fish processing industry has experienced significant growth, playing an important role in the world economy. The increased exploration of marine resources contributes to the generation of considerable amounts of biowaste, which ends up as discards. In the face of the resultant disposal and environmental problems, many efforts have been made to deal with the fishery waste in more efficient ways. Nowadays, these by-products are regarded as important sources of high added value compounds, such as hydroxyapatite, collagen, gelatin, lipids, enzymes, hydrolysates and bioactive peptides, with great potential for human health applications. The present paper aims to review the current methods of extraction and characterization of added value products from fish by-products, as well as their actual and potential applications.
- A fast responsive chromogenic and near-infrared fluorescence lighting-up probe for visual detection of toxic thiophenol in environmental water and living cellsPublication . Wu, Juanjuan; Su, Dongdong; Qin, Caiqin; Li, Wei; Rodrigues, João; Sheng, Ruilong; Zeng, LintaoThiophenols as high toxic environmental pollutants are poisonous for animals and aquatic organisms. Therefore, it is indispensable to monitor thiophenols in the environment. Herein, a novel near-infrared fluorescent probe was developed for the detection of thiophenols, which was easily prepared by one-step coupling of 2,4-dini trobenzenesulfonyl chloride with Nile blue. The probe showed a significant near infrared (∼675 nm) fluores cence “turn-on” response to thiophenols with some good features including chromogenic reaction, high sensi tivity and selectivity, fast response, near-infrared emission along with low detection limit (1.8 nM). The probe was employed to rapidly and visually determine thiophenols in several industrial wastewaters with good re coveries (90–110%). Moreover, this probe has been demonstrated good capability for imaging thiophenol in HeLa cells
