Protecção radiológica em Portugal: análise da nova directiva internacional (oportunidades e ameaças)
A Comissão Europeia irá lançar, num futuro próximo, uma nova directiva relativa à protecção radiológica - Basic Safety Standards – a qual irá substituir, num único
documento, os actualmente existentes. Durante as últimas três décadas, em Portugal, a protecção radiológica contra radiações ionizantes tem sido regulada segundo cinco directivas, publicadas entre 1989 e 2003. Têm sido relatados vários incidentes ocorridos em ambiente clínico, nomeadamente naqueles que operam com radiação ionizante, pois na maioria dos casos, as regras, boas práticas e infra-estruturas não estão adequadas para esta finalidade. As questões ligadas com esta temática estão agora em análise e sob discussão pública. É, contudo, importante entender os desafios e requisitos da nova directiva para melhorar e assegurar a excelência dos resultados nas organizações de cuidados de saúde. Este novo documento reúne as abordagens da International Commission on Radiation Protection (ICRP), International Atomic Energy Agency (IAEA), Nuclear Energy Agency (NEA), International Radiation Protection Association (IRPA) e World Health Organization (WHO) e também de outros especialistas na matéria. O propósito da nova directiva aplicada a qualquer exposição previamente planeada baseia-se no princípio ALARA (optimização das práticas, justificação da exposição e limitação da dose). O objectivo deste estudo é, na opinião das partes interessadas, identificar as oportunidades que podem resultar da implementação da nova directiva
Sexualidade em adultos com paralisia cerebral
Orientação: Patrícia Pascoal ; co-orientação : Ana PriosteDada a escassez de estudos sobre a sexualidade em pessoas com paralisia cerebral, este estudo pretende, com recurso a uma amostra de adultos (N = 19): (1) explorar as perceções, necessidades e os conhecimentos associados à sexualidade; (2) identificar os fatores associados à satisfação na vida afetivo/relacional e sexual de adultos com paralisia cerebral. Foi conduzido um estudo qualitativo transversal e exploratório. A amostra foi recolhida através de um pedido de colaboração com associações que apoiam pessoas com paralisia cerebral (e.g., Associação de Paralisia Cerebral, em Lisboa, Associação Centro de Vida Independente, Associação Mithós e Associação Salvador). Como critérios de inclusão na amostra foram estabelecidos: (1) compreender e escrever em português; (2) viver em Portugal; (3) ter mais de 18 anos; (4) ter um diagnóstico de paralisia cerebral, sem alterações cognitivas; (5) responder de forma individual, i.e., sem a presença de outras pessoas. Os participantes responderam a um questionário on-line, numa plataforma de opensource, com cinco perguntas abertas focadas nas perceções e necessidades relativas à sexualidade. Os dados foram analisados através da Análise Temática que conduziu à identificação de diversas propriedades do construto “prazer sexual” permitindo a identificação das significações que lhes estão associadas funções, contextos, processos e fontes.Given the scarcity of studies on sexuality in people with cerebral palsy, this study intends, with the help of a sample of adults (N = 19): (1) to explore the perceptions, needs and knowledge associated with sexuality; (2) to identify the factors associated with satisfaction in the affective / relational and sexual life of adults with cerebral palsy. A qualitative transversal and exploratory study was conducted. The sample was collected through a request for collaboration with associations that support people with cerebral palsy (eg, Cerebral Palsy Association, Lisbon, Independent Living Center Association, Mithós Association and Salvador Association). As criteria for inclusion in the sample were established: (1) understand and write in Portuguese; (2) live in Portugal; (3) be over 18 years of age; (4) have a diagnosis of cerebral palsy, without cognitive alterations; (5) respond individually, i.e. without the presence of other persons. Participants responded to an online questionnaire on an opensource platform with five open-ended questions focused on perceptions and needs related to sexuality. The data were analyzed through the Thematic Analysis that led to the identification of several properties of the "sexual pleasure" construct, allowing the identification of the meanings associated with functions, contexts, processes and sources
Teacher training forCLIL in Higher Education: challenges in blended learning
Researchers and foreign language teachers of ReCLes.pt (the Network Association of Language Centers in Higher Education in Portugal) would like to share recent research on a blended learning format for teacher training for CLIL (Content and Language Integrated Learning), based on a course carried out in the 2nd semester of 2016/2017 for teachers at four geographically disperse polytechnic instituts in Portugal. The course was implemented in these four different educational environments and had as trainees teachers of other subjects, representing specialty areas such as Experimental and Exact Sciences, Technology, Engineering, and Management. Together, the trainers from each of the four schools designed and carried out the teacher training, online and in loco, with initial face-to-face (F2F) sessions to establish a community of practice and a common objective – to learn to create conditions for learning that simultaneously promote the proposed subject and the foreign language through which it is taught. The framework of the b-learning course is the widely-used CLIL Training Guide (Morgado et al. 2015), available at http://recles.pt/, which includes techniques for scaffolding to build new concepts upon previously acquired competences and terminologically-inspired approaches and instruments for acquiring the much-needed specialist terminology of each subject. Also covered are the principles of how to teach effectively through English, activating and consolidating linguistic competences, considering aspects of classroom management and student learning styles. The assynchronous and F2F sessions also consisted of individual orientation and tutorial work with the teacher trainees, followed by classroom observation of the resulting CLIL module and interviews with the students and the teacher trainees. By ensuring the best possible application of the teachers’ new teaching competences, we aim to better understand just how students in higher education are receiving this new approach to learning through a foreign language. Overall, the present experience will serve for further national and international editions of this valuable opportunity to be trained in CLIL for higher education as it has allowed for reflection on the potential and the challenges for blended learning – ranging from the cohesion, distribution, and relevance of the topics covered to management of time for executing the assignments and to issues related to personal learning spaces. Learner satisfaction (for the teacher trainers and the students of these higher education CLIL modules) is high although realistic expectations about time are a consistent difficulty to be negotiated.info:eu-repo/semantics/publishedVersio
Genetics of pinus pinaster Aiton with cytoplasmic and nuclear markers
Tese de Doutoramento apresentada no Department of Forest Genetics and Plant Phisiology da Swedish University of Agricultural Sciences, em UmeaThis thesis summarizes and discusses results of three studies in which biochemical and
molecular techniques were used to study the genetic variation in Pinus pinaster. In
particular, the investigation focused on: (i) the within- and among-population genetic
diversity in the region hypothesised as a putative refugium for the species during the last
glaciation; (ii) the comparison of nuclear and cytoplasmic estimates of diversity within
and between two regions of the species; and (iiii) the design of a test for provenance
identification using knowledge about the levels of genetic variation between the two
regions.
The distribution of the genetic variation of P. pinaster in Portugal, as revealed by
chloroplast microsatellites (cpSSR), indicated that there are low levels of differentiation
among populations and that the diversity is found mainly within populations. No
discernable geographic pattern was found. Evidences of strong anthropogenic influence
associated with extensive gene flow could explain these findings. Fossil, charcoal and
palynological records supported the presence of the species in Portugal before and during
the last glaciation; therefore, the hypothesis of a putative refugium in this country cannot
be excluded.
The genetic variation of 24 populations from France and Portugal was investigated with
amplified fragments length polymorphisms (AFLPs) and cpSSRs. Both types of markers
could discriminate between the two provenances and the diversity of the French
provenance was higher compared with that from Portugal. Similar differentiation
estimates were found with nuclear and cytoplasmic markers. Extensive gene flow could
account for this result, but higher mutation rates and homoplasy at cpSSR loci are not to
be excluded. Despite the different modes of inheritance, a high correlation was found
between the genetic distances matrices with both types of markers, which suggests that
migration surpassed genetic drift in moulding the genetic structure of this species in the
regions studied.
A provenance diagnostic test was designed, based on cpSSRs, to screen the putative
origin of stands of P. pinaster in southwestern France and compared with the currently
used terpene-based test. Five stands of unknown origin were diagnosed with both tests.
The cpSSR-based test proved to be faster and more accurate to determine if stands were
of French or northwest Iberian (Portugal and Galicia) origin. The result obtained was
probably due to the higher capability of the DNA-based markers to discriminate between
both provenances, compared to that of the terpene markers
A crise das instituições portuguesas: no rumo duma metodologia de intervenção institucional
Existe entre nós, portugueses, o sentimento
generalizado de que as nossas Instituições funcionam
mal.
Na procura de uma «mudança institucional»,
começaremos por tentar definir alguns contornos
precisos dessa crítica generalizada à luz das teorias
institucionais, essencialmente as de influência
analítica. Seguidamente traçaremos os pontos
fundamentais de uma nova Metodologia de
Intervenção, influenciada esta, essencialmente, pelo
modelo Grupanalítico.
Um trabalho mais aprofundado sobre esta
Metodologia, e que foi por nós já realizado, será

The intention of visiting a new restaurant social media motivated: A comparison of social circle influence vs. Social Media Influencers
Dissertation presented as the partial requirement for obtaining a Master's degree in Data Driven Marketing, specialization in Digital Marketing and AnalyticsSocial Media platforms have become important tools for companies to track trends and customers’ desires, people have started to share their experiences with each other online faster and more efficiently. Social Media Influencers (SMI) for restaurant recommendations have been studied for the past few years, however, there is still a lack of studies comparing the influence of people’s social circle and the information they receive through digital influencers. Therefore, the main purposes of this dissertation were to identify and understand which factors are most valued in SMI and people’ social circle regarding restaurant recommendations and verify which endorsers tend to impact more the intention to visit a restaurant trough social media. The study was conducted by adapting two existing models: Source Credibility and Source Attractiveness; and deploying a questionnaire which collected a sample of 213 Portuguese respondents. To analyse this data, we used the Partial Least Square Structural Equation Modelling through the SmartPLS4 software. It has been found that expertise and trustworthiness of a person have a significant correlation with his/her credibility. People tend to attribute more credibility based on trustworthiness to their social circle in comparison to their opinion regarding SMI, but the model estimated shows that people are aware of SMI influence specially through their Attractiveness. It was also possible to conclude that people tend to be influenced face-to-face by their social circle
Rooting and survival of cork oak cuttings
I Congresso Luso-Brasileiro de HorticulturaThe cork oak (Quercus suber L.) has remarkable ecological, social and economic value
in the Mediterranean region. Due to the growing economic interest in cork, human
intervention in the plant production and renewal of this species is crucial. Thus, the
optimization of the propagation methodologies to produce selected and improved trees
for high quality cork production is a key factor in the species improvement program.
Rooting and survival of cuttings are greatly affected by several external and internal
factors. To circumvent this problem, experiments were made using young seedlings as a
source of cork oak cuttings for two consecutive years. We studied the influence of the
application of synthetic auxins, indole-3-butyric acid (IBA) and α-naphthalene acetic acid (NAA), the IBA concentration and the basal bark removal in rooting and survival
of cork oak cuttings. The IBA improved the rooting, the survival and the mean length of
the longest root per rooted cutting, but not the mean number of primary roots produced.
The basal bark removal associated with 0.5% of IBA gave the highest percent of rooting
and plant survival (60% and 54%, respectively). The application of 0.1% of NAA had
no significant influence on the rooting and survival. Thus, it is possible to draw the
conclusion that wounding along with 0.5 % IBA produced the highest percentage of
rooting and survival with cuttings planted in April, however complementary studies
involving different physical and chemical conditions are requiredinfo:eu-repo/semantics/publishedVersio
Intervenções do enfermeiro na prevenção de quedas na criança hospitalizada: scoping review
OBJECTIVES: map both nursing interventions for the prevention of falls in paediatric age during hospitalization and the instruments for assessing the risk of falls in paediatrics. METHODS: scoping review according to the protocol of Joanna Briggs Institute, with acronym PCC (P - children, C - fall preventive nursing interventions and instruments for assessing the risk of falling, C - hospital admission), in three sources of information (EBSCO, PubMed and SciELO). RESULTS: the sample consisted of seven articles. The education of the child/family is the basis of the interventions, and the instruments for assessing the risk of falling identified were: Humpty Dumpty Falls Scale, GRAF PIF, CUMMINGS, I'M SAFE and CHAMPS. CONCLUSIONS: the education of children/parents on preventive measures is important and should be reinforced during hospitalization, using different methodologies. The Humpty Dumpty Falls Scale was the most analyzed.Objetivos: mapear tanto as intervenções de enfermagem de prevenção de quedas em idade pediátrica durante o internamento hospitalar quanto os instrumentos de avaliação do risco de queda em pediatria.

Resultados: a amostra foi constituída por sete artigos. A educação da criança/família é a base das intervenções, e os instrumentos de avaliação do risco de queda identificados foram: Humpty Dumpty Falls Scale, GRAF PIF, CUMMINGS, I'M SAFE e CHAMPS. Conclusões: a educação das crianças/pais sobre as medidas preventivas é importante e deve ser reforçada durante o internamento, sendo utilizadas diferentes metodologias. A escala Humpty Dumpty Falls Scale foi a mais analisada.info:eu-repo/semantics/publishedVersio
Uma manifestação de borreliose de Lyme?
Introdução: A borreliose de Lyme é uma doença infecciosa multissistémica que se assume como emergente em Portugal. A apresentação atípica no nosso país, provavelmente associada à infecção por Borrelia lusitaniae, tem dificultado o diagnóstico correcto desta espiroquetose. Justifica-se, pelo motivo enunciado, um maior nível de suspeição perante manifestações inespecíficas da doença. A morfeia é uma dermatose cuja associação com a infecção por Borrelia burgdorferi sensu lato tem sido alvo de investigação sistemática, mas não está ainda esclarecida. O objectivo do presente trabalho consiste na determinação da possibilidade de uma correlação entre a morfeia e a borreliose de Lyme na região da Guarda. Métodos: Este estudo observacional descritivo foi realizado com o intuito de avaliar retrospectivamente uma amostra de dez doentes com morfeia seguidos no Serviço de Dermatologia da Unidade Local de Saúde da Guarda. Os dados necessários foram obtidos mediante revisão dos processos clínicos e entrevista dos doentes. Foi efectuada uma análise estatística descritiva através do cálculo de medidas como frequências, percentagens e médias.
Resultados e Discussão: Os dez doentes da amostra estudada eram naturais e residentes no distrito da Guarda, região em que a presença de Ixodes ricinus já foi referida e onde foram detectados alguns casos seropositivos para borreliose de Lyme. O enquadramento epidemiológico efectuado permitiu verificar que a localização das habitações e respectivas características, o contacto com animais e as ocupações profissionais e recreativas condicionam a exposição dos doentes a ambientes propícios à mordedura de carraça, ainda que a mesma tenha sido assinalada em apenas dois casos. Relativamente à informação clínica, constatou-se, nalguns doentes, a existência de sintomatologia acompanhante das lesões de morfeia, sugerindo a possível associação destas a outras manifestações eventualmente relacionadas com a referida espiroquetose. Não foram encontrados antecedentes de sinais clínicos específicos de borreliose de Lyme ou de outras patologias causadas por mordedura de carraça. Testes serológicos de rastreio foram os únicos exames complementares de diagnóstico solicitados para avaliação da possível infecção por Borrelia burgdorferi sensu lato nestes doentes. Conclusões: A verificação da exposição dos doentes a factores de risco para mordedura de carraça e as informações clínicas obtidas permitem confirmar a necessidade de investigar de forma sistemática, por métodos complementares de diagnóstico adequados que deverão ir para além dos testes de rastreio, a origem borreliana da esclerodermia circunscrita.Introduction: Lyme borreliosis is a multisystem infectious disease believed to be
emerging in Portugal. The atypical presentation in our country, possibly related
to the infection with Borrelia lusitaniae, has lead to difficulties in diagnosing this
spirochetosis. Therefore, a higher level of suspicion is required when evaluating
non-specific manifestations of the disease. Although still not clarified, morphea
is a dermatosis which linkage to Borrelia burgdorferi sensu lato infection has
been open to systematic investigation. The aim of the present research is to
determine the possibility of a correlation between morphea and Lyme
borreliosis, in Guarda region.
Methods: This observational descriptive study was designed to retrospectively
evaluate a sample of ten patients with morphea followed up at the Unidade
Local de Saúde da Guarda Dermatology Department. The data was collected
by reviewing clinical files and by patients’ interviewing. A descriptive statistical
analysis was performed through the calculus of measures like frequencies,
percentages and means.
Results and Discussion: All patients were born and are living in Guarda district,
where Ixodes ricinus has already been identified and some Lyme borreliosis’
seropositive cases have been detected. An epidemiological approach lead to
the findings that the location and characteristics of the houses, the contact with
animals and the professional and recreational activities of the patients expose
them to environmental risk for tick bites, even if bites were recalled in only two cases. Concerning clinical information, symptoms accompanying the morphea
lesions and coexistence with other manifestations potentially associated with
the studied spirochetosis were present in some cases. There was no previous
history of specific signs of Lyme borreliosis or other vector-borne diseases.
Serologic first-tier testing was the only diagnostic modality used to assess the
possible infection with Borrelia burgdorferi sensu lato in these patients.
Conclusions: Exposure to risk factors for tick bites and the clinical data
determine the need for further investigation of a borrelian etiology for localized
scleroderma in these patients, by the use of appropriate laboratory
examinations
Setor bancário português: análise da perceção de qualidade, equidade, valor, satisfação e confiança da população portuguesa
As Instituições Bancárias dependem, quase inteiramente, do bem-estar económico e da
confiança da comunidade que servem, e estão inseridas num mercado altamente
concorrencial, tornando-se mais premente a necessidade de saber o que os clientes mais
valorizam.
Tendo em consideração os acontecimentos económicos recentes, importa referir que durante o
processo de expansão de uma economia em crescimento, as pessoas exigem cada vez maior
quantidade e melhores serviços financeiros. Para que aconteça o desenvolvimento financeiro,
é então necessário atender a estas exigências e expetativas, oferecendo sofisticação,
quantidade e qualidade nos serviços prestados. Por conseguinte, o objetivo principal da
presente dissertação centra-se na análise das perceções de Qualidade, de Equidade, de Valor,
de Satisfação e de Confiança que os portugueses fazem acerca dos serviços no setor bancário
português.
De forma a concretizar a investigação foi aplicado um inquérito, no âmbito do qual se
inquiriram 280 clientes de instituições bancárias.
Os resultados revelaram que o construto com melhor avaliação foi a satisfação, e pelo
contrário, o valor percebido é o construto que reúne as avaliações mais baixas.
Para além dos resultados acima mencionados, foi também estudada a estrutura das relações
entre os construtos, e concluiu-se que a equidade influencia positivamente a Qualidade, o
Valor Percebido e a Satisfação. Adicionalmente o Valor Percebido é influenciado também
pela qualidade, e ambos influenciam a Satisfação.
Por fim, a Confiança é influenciada por todos os construtos, sendo a Satisfação a dimensão
com menor impacto e o Valor Percebido apresenta-se como a dimensão com maior impacto
na Confiança.Banking Institutions depend almost entirely on the economic well-being and the trust of the
community they serve and are embedded in a highly competitive market, making the need to
know and valued customers more pressing.
Taking into account recent economic developments, it should be noted that, in the process of
expanding a growing economy, people are demanding more and better financial services. For
financial development to occur, it is then necessary to meet these requirements and
expectations, offering sophistication, quantity and quality in the services provided. Therefore,
the main objective of this dissertation is centered in the analysis of the perceptions of Quality,
Equity, Value, Satisfaction and Confidence that the Portuguese make about services in the
Portuguese banking sector.
In order to carry out the investigation, a survey was carried out in which 280 clients of
banking institutions were surveyed.
The results showed that the construct with the best evaluation was satisfaction and, on the
contrary, perceived value was the construct that brings together the lowest evaluations.
In addition to the aforementioned results, the structure of the relationship between the
constructs was also studied, and it was concluded that equity positively influences Quality,
Perceived Value and Satisfaction. Additionally, Perceived Value is also influenced by quality
and both influence Satisfaction.
Finally, Confidence is influenced by all constructs, Satisfaction being the dimension with the
least impact and Perceived Value the dimension with the greatest impact on Confidence
