During their life cycle, plants are typically confronted by simultaneous biotic and abiotic stresses. Low inorganic phosphate (Pi) is one of the most common nutrient deficiencies limiting plant growth in natural and agricultural ecosystems, while insect herbivory accounts for major losses in plant productivity and impacts ecological and evolutionary changes in plant populations. Here, we report that plants experiencing Pi deficiency induce the jasmonic acid (JA) pathway and enhance their defense against insect herbivory. Pi-deficient Arabidopsis (Arabidopsis thaliana) showed enhanced synthesis of JA and the bioactive conjugate JA-isoleucine, as well as activation of the JA signaling pathway, in both shoots and roots of wild-type plants and in shoots of the Pi-deficient mutant pho1 The kinetics of the induction of the JA signaling pathway by Pi deficiency was influenced by PHOSPHATE STARVATION RESPONSE1, the main transcription factor regulating the expression of Pi starvation-induced genes. Phenotypes of the pho1 mutant typically associated with Pi deficiency, such as high shoot anthocyanin levels and poor shoot growth, were significantly attenuated by blocking the JA biosynthesis or signaling pathway. Wounded pho1 leaves hyperaccumulated JA/JA-isoleucine in comparison with the wild type. The pho1 mutant also showed an increased resistance against the generalist herbivore Spodoptera littoralis that was attenuated in JA biosynthesis and signaling mutants. Pi deficiency also triggered increased resistance to S. littoralis in wild-type Arabidopsis as well as tomato (Solanum lycopersicum) and Nicotiana benthamiana, revealing that the link between Pi deficiency and enhanced herbivory resistance is conserved in a diversity of plants, including crops.

Aims: To improve engagement of Health Visitors and Community Practitioners delivering the Healthy Child Programme with fathers. To evaluate a one-day, father-focused workshop with a supporting handbook for Practitioners. To identify institutional and organisational barriers to engagement with fathers. Background: The UK government policy encourages health professionals to engage with fathers. This derives from robust evidence that fathers’ early involvement with their children impacts positively on emotional, behavioural and educational development. Yet, there is little evidence that the importance of engaging fathers is reflected in Health Visitor training or that primary-care services are wholly embracing father-inclusive practice. The Fatherhood Institute (FI), a UK charity, has developed a workshop for Practitioners delivering the Healthy Child Programme. Method: A ‘before and after’ evaluation study, comprising a survey followed by telephone interviews, evaluated the impact of the FI workshop on Health Visitors’ and Community Practitioners’ knowledge, attitudes and behaviour in practice. A total of 134 Health Visitors and Community Practitioners from eight NHS Trusts in England attended the workshop from November 2011 to January 2014 at 12 sites. A specially constructed survey, incorporating a validated questionnaire, was administered before the workshop, immediately afterwards and three months later. Telephone interviews further explored participants’ responses. Findings: Analysis of the questionnaire data showed that the workshop and handbook improved participants’ knowledge, attitudes and behaviour in practice. This was sustained over a three-month period. In telephone interviews, most participants said that the workshop had raised their awareness of engaging fathers and offered them helpful strategies. However, they also spoke of barriers to engagement with fathers. NHS Trusts need to review the training and education of Health Visitors and Community Practitioners and take a more strategic approach towards father-inclusive practice and extend services to meet the needs of fathers.

This paper describes the development and evaluation of web-based museum trails for university-level design students to access on handheld devices in the Victoria and Albert Museum (V&A) in London. The trails offered students a range of ways of exploring the museum environment and collections, some encouraging students to interpret objects and museum spaces in lateral and imaginative ways, others more straightforwardly providing context and extra information. In a three-stage qualitative evaluation programme, student feedback showed that overall the trails enhanced students’ knowledge of, interest in, and closeness to the objects. However, the trails were only partially successful from a technological standpoint due to device and network problems. Broader findings suggest that technology has a key role to play in helping to maintain the museum as a learning space which complements that of universities as well as schools. This research informed my other work in visitor-constructed learning trails in museums, specifically in the theoretical approach to data analysis used, in the research design, and in informing ways to structure visitor experiences in museums. It resulted in a conference presentation, and more broadly informed my subsequent teaching practice.

Introduction: Childhood cancers are rare and community based health care professionals have limited experience in caring for these children and often even less experience in providing their palliative care. It is well recognised that the provision of palliative care falls beyond the remit of any one profession, thus inter professional working is the standard model. This qualitative study aims to examine the experiences of the range of health care professionals involved in providing palliative care at home for children with cancer, focusing on how knowledge is exchanged; the level of communication and support both interprofessionally and at the community/specialist interface. It also aims to examine interprofessional collaboration in palliative care; identifying healthcare professional's perceptions of problems involved, interprofessional boundaries, specific areas of the organisation or provision of care that could be enhanced through changes in practice, support issues and the educational needs of health professionals. Methods The study involves three types of data collection; in-depth interviews, facilitated case discussion (FCD) and field notes from up to 20 cases (a "case" refers to the provision of palliative care to one child). Cases are selected from children who were treated at one regional childhood caner centre. For each case the community based health care professionals (for example the GP, community nurse or health visitor) involved in the care of the child at home are invited to participate in a one-to-one tape recorded in-depth interview followed by a group discussion in the form of a FCD. Field notes are completed following each interview. Data analysis follows a grounded theory approach. The term "social worlds theory" (SWT) his used to define a type of social organisation with no fixed or formal boundaries (such as membership boundaries), for example the range of health professionals that work together to provide palliative care. The boundaries of SW's are determined by the interaction and communication between recognised organisations, such as community nursing teams and general practitioners. SWT examines encounters between different professional groups and can be used to extend knowledge in both the organisation (for example general practice) and the content of what is being provisioned (for example, palliative care). The use of SWT in the analysis of the data is through examining the ethos of the different professions and the associated individual approaches to palliative care, exploring how this determines their roles in the provision of palliative care. Results 10 cases have so far been completed: 47 1:1 interviews (with a range of between 2-7 health care professionals being involved in each case): ( 9 x GP, 19 x CCN, 4 x DN, 3 x HV, 1 x HV assistant 7 x paediatric palliative care nurses, 1 x home support worker, 1 x OT, 1 x physiotherapist, 1 x community paediatrician) and 5 x FCD. The range of participants in the FCDs reflected that of the individual interview sampler. Data obtained to date gives clear insight into the personal experience of the individual health care professional in providing palliative care. Two themes emerging from the data will be focused upon: the continuity of care provision throughout treatment and palliation and the emotional burden experiences by the health care professional. Conclusions SWT can provide a useful framework in examining the social worlds of a disparate group of health care professionals working together for the first and maybe, the only time. A wide variation in the continuity of care provision has been found not only between professions, but also within professions. The emotional burden is evident across the professions.

This thesis nalyzes the wayfinding in Landscape Museum of Contemporary Art (MPAC), based on the Institute of Contemporary Art CACI, Minas Gerais, Brazil and the Museum of Contemporary Art of the Serralves Foundation, Porto, Portugal. The study focuses on the interrelationship of the public/visitors with the landscape, architecture and contemporary art museums in these, in order to understand visual perception and apprehension of such an environment for their users. For both were confronted documentation (visual and written) and people talk. The main hypothesis put forward is that the audience/visitor MPAC appreciates the interrelationship between the natural environment (park/garden) and built environment (the works of contemporary art and the galleries), giving equal value to both. To complement this, a second hypothesis is that during the visit to MPACS, visitors define their paths spontaneously, but strongly influenced by existing visual indicators (maps, signage and striking landscape elements), which facilitate the readability of space, which also contribute to the offered services and the experiences of similar institutions. The analytical basis of the research used the concepts of legibility (LYNCH, 2009), wayfinding (GIBSON, 2009; ARTHUR, PASSINI, 2002; WEISMAN, 1982), Experiential Cotinnum (TUAN, 1985), Space Bound (CRUZ PINTO, 2007) and habitus (BOURDIEU, 1992). Methodologically was used qualitative research (DEMO 2000) by means of a case study (YIN, 2005; STAKE, 1999) and participant observation (WHYTE, 2005). In the two institutions interviews with researchers and curators, behavior observation and questionnaires from employees, trainees, monitors and the public/visitor of the two museums were performed. Although partially referende the initial hypothesis, the research showed that the public/visitor value appears more natural environments, they experience a greater intensity and in addition to the factors listed in the second case, your perception and definition of paths suffer significant influence of emotional relations established with space. Generally the audience/visitor adapts easily to different demands of contemporary art exhibition in the two museums and the built environment (park/garden and museum) interferes with your reading path during the visit, perceived by the public/visitor condition as a factor that favors the enjoyment of works on different mounts (wayfinding), though often become a factor that hinders the legibility of the building and its built environment

Este artigo tem como objetivo mostrar que é possível incentivar a aprendizagem em museus através da construção de comunidades virtuais, com base em repositórios de objetos de aprendizagem (OA), ferramentas comunicacionais e produção de OA por parte dos visitantes. O enfoque é incentivar a aprendizagem no sentido de motivar a participação/envolvimento do visitante nas atividades da comunidade virtual. Nesta perspectiva, partimos do pressuposto de que a informação, a comunicação, a interação e a colaboração são essenciais para o processo de aprender no contexto informal dos museus. Acreditamos que a interação e a colaboração são partes integrantes do processo de aprendizagem proporcionado por comunidades virtuais e que o principal recurso de aprendizagem oferecido nessas comunidades são os objetos de aprendizagem. Assim sendo, por meio de um entendimento do aprender baseado na comunicação e na linguagem, percebemos os museus interativos como espaços discursivos em que os visitantes mergulham e por eles são modificados. Neste sentido, argumentamos que as comunidades virtuais de aprendizagem, com a possibilidade de virtualizar a linguagem, são excelentes mecanismos para ampliar o poder comunicacional dos museus, criando novas estratégias comunicativas. Para atingir o objetivo, foi necessário reunir quatro conceitos técnicos da área de informática, são eles: comunidades virtuais de aprendizagem; objetos de aprendizagem; metadados e mapas de tópicos. A junção destes conceitos permitiu a construção do ambiente de comunidade virtual, denominada CV-Muzar. Diante do exposto, de modo a identificar os meios pelos quais se podem motivar os visitantes a realmente produzirem novos conhecimentos durante sua visita informal ao museu, examinando essa questão tanto do ponto de vista quantitativo, como também qualitativamente, foi realizada uma experimentação do ambiente com um grupo de pessoas convidadas segundo suas áreas de formação.

O golfinho-comum (Delphinus delphis) é uma das espécies de cetáceos mais abundantes e mais amplamente distribuídas em todo o planeta, sendo a espécie mais abundante ao longo da costa continental portuguesa. Algumas das suas principais presas apresentam um elevado interesse comercial estando por isso, muitas vezes, associado a capturas acidentais em artes de pesca. Contudo, estudos mais recentes sobre os hábitos alimentares desta espécie na costa portuguesa são escassos. Assim, este estudo visa contribuir para a avaliação da ecologia alimentar deste cetáceo na costa portuguesa através de índices de importância numérica, ocorrência e do peso estimado, permitindo descrever a dieta não só em termos qualitativos, mas também em termos quantitativos. Foram examinados os conteúdos estomacais de 55 golfinhoscomuns arrojados na costa continental portuguesa (norte e centro) entre 2004 e 2015. De um total de 6699 presas identificadas, 66% pertenciam à classe dos peixes, 32% eram cefalópodes e 3% eram crustáceos. As espécies-presa de peixes mais importantes em termos de importância numérica foram os góbios (Gobiidae) e o carapau (Trachurus sp.). Em relação à ocorrência foram o góbio (Gobiidae) e a sardinha (Sardina pilchardus), seguidas de carapau, as espécies predominantes. Relativamente ao peso, a sardinha foi a espécie-presa predominante, seguida de faneca (Trisopterus luscus) e carapau. Quanto aos cefalópodes, a lula-bicuda (Alloteuthis sp.) foi a espécie mais importante, tanto em termos de importância numérica como em termos de ocorrência. A lula-comum (Loligo sp.) foi a mais importante em termos de peso total estimado. As espécies demersais dominaram a dieta do golfinho-comum, com uma percentagem numérica de 40%. Foram detetadas diferenças entre machos e fêmeas na composição da dieta relativamente à sardinha. Foram detetadas diferenças entre indivíduos maturos e imaturos na composição da dieta relativamente à lula-bicuda. A diversidade de presas observada nos conteúdos estomacais do golfinho-comum sugere um comportamento oportunista, consumindo as presas mais abundantes, localmente. As interações com as artes de pesca podem levar a uma elevada mortalidade destes mamíferos marinhos. Deste modo, a realização de estudos sobre os hábitos alimentares de cetáceos permitem uma melhor compreensão das possíveis interações com a pesca, e a melhoria de estratégias de conservação para evitar a morte destes animais.

O presente relatório de qualificação profissional surgiu no âmbito da Unidade Curricular de Prática Pedagógica Supervisionada, pertencente ao plano de estudos do Mestrado em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico. Deste modo, pretende evidenciar o percurso formativo da mestranda, refletindo as experiências e as competências desenvolvidas nos dois níveis educativos, tendo em vista a construção de um perfil duplo. Neste documento reflexivo espelha-se, portanto, o desenvolvimento de práticas sustentadas num quadro teórico e legal, construído ao longo do percurso formativo da mestranda, nas caraterísticas do contexto onde foram desenvolvidas as práticas nos dois níveis educativos e nos conhecimentos obtidos sobre a individualidade de cada criança, os seus interesses e necessidades. Finda-se este mesmo documento, com uma análise reflexiva de todo o percurso desenvolvido, focando-se as competências adquiridas, evidenciando-se, deste modo, a progressão da mestranda ao longo do mesmo. Durante as suas ações a mestranda perfilhou a metodologia de investigação-ação, espelhada ao longo deste relatório de estágio, desenvolvendo os processos de observação, planificação, ação, avaliação e reflexão, de uma forma cíclica, articulando-os. Esta metodologia e os instrumentos e estratégias desenvolvidos com base na mesma permitiram à mestranda a melhoria das suas práticas, possibilitando-lhe um olhar crítico e reflexivo sobre as mesmas, bem como, sobre a educação na Educação Pré- Escolar e no 1.º Ciclo do Ensino Básico, proporcionando, desta forma, o desenvolvimento de competências investigativas e reflexivas. Todo este percurso formativo possibilitou à mestranda o desenvolvimento de competências pessoais e profissionais na construção de um perfil generalista, apresentando-se como as primeiras “pegadas” de uma aprendizagem ao longo da vida.

Increasing abundance of non-commercial sprats and decreasing biomass and landings of commercial anchovies and sardines justify the need to study the feeding ecology and trophic niche overlap of these planktivorous species in the Gulf of Lions. Their diet has been investigated on the basis of stomach content and stable isotope analyses in 2011 and 2012 according to different depths and regions in the study area. The main prey were Corycaeidae copepods, Clauso/Paracalanus, Euterpina acutifrons and Microsetella, for sprats and small copepods, such as Microsetella, Oncaea and Corycaeidae, for anchovies and sardines. This is the first time that the diet of sprats is described in the Gulf of Lions. Sprats fed on a larger size spectrum of prey and seem to be more generalist feeders compared to anchovies and sardines. Ontogenetic changes as well as spatial and temporal variations of the diet occurred in the three species. Stable isotope analysis revealed mobility of sardines and sprats among feeding areas while anchovies exhibited preferred feeding areas. Sprats showed a higher relative condition assessed by C/N ratios than sardines and anchovies. Our results showed an overlap of the trophic niches for the three species, indicating a potential trophic competition in the Gulf of Lions.
