Exploring resilience in nursing and midwifery students: a literature review

AIM: The aim of this study was to explore the concepts of 'resilience' and 'hardiness' in nursing and midwifery students in educational settings and to identify educational interventions to promote resilience.

BACKGROUND: Resilience in healthcare professionals has gained increasing attention globally, yet to date resilience and resilience education in nursing and midwifery students remain largely under-researched.

DESIGN: An integrative literature review was planned, however, only quantitative evidence was identified therefore, a review of quantitative studies was undertaken using a systematic approach.

DATA SOURCES: A comprehensive search was undertaken using Medline, CINAHL, Embase, PsycINFO and Maternity and Infant Care databases January 1980-February 2015.

REVIEW METHODS: Data were extracted using a specifically designed form and quality assessed using an appropriate checklist. A narrative summary of findings and statistical outcomes was undertaken.

RESULTS: Eight quantitative studies were included. Research relating to resilience and resilience education in nursing and midwifery students is sparse. There is a weak evidence that resilience and hardiness is associated with slightly improved academic performance and decreased burnout. However, studies were heterogeneous in design and limited by poor methodological quality. No study specifically considered student midwives.

CONCLUSION: A greater understanding of the theoretical underpinnings of resilience in nursing and midwifery students is essential for the development of educational resources. It is imperative that future research considers both nursing and midwifery training cohorts and should be of strong methodological quality.

STUDENT’ S ENGAGEMENT IN SCHOOL: A LITERATURE REVIEW

Students’ Engagement in School has been the focus of debate concerning academic success and school dropout, and pointed out as a mean to address the problems affecting our schools and their students, not only for having value in itself, but also for being an important mediator between several academic variables. This paper reviews the research and literature on this concept and its relations with personal and contextual variables, as well as with academic performance, with the aim of summarizing the main relationships found. Literature presents a significant number of studies which sustain that personal variables, such as self-efficacy and self-concept, as well as contextual - peers, school, family- are related with school engagement. The adoption of mastery goals, for instance, has a positive impact on school, as they are related with the use of cognitive and self-regulatory strategies by students. Positive relationships with peers, teachers support and the quality of family relations are associated with higher levels of engagement and academic performance, while negative experiences, such as bullying, are related with educational difficulties. Following this, we reflect about the relevance of studying engagement in school, in the context of widespread financial crisis, and emphasize the need to rethink educational institutions considering the paradigmatic changes that currently occur.

Lacertid lizards as bioindicators of agricultural contamination

Apesar do recente aumento no número de estudos, os lagartos persistem como um dos grupos menos estudados em ecotoxicologia e o desconhecimento em relação à sua resposta à contaminação ambiental é enorme. A nível europeu, os lacertídeos têm sido identificados como potenciais espécies modelo para a ecotoxicologia com répteis. O principal objectivo deste projecto era determinar se um lacertídeo abundante pertencente ao género Podarcis, podia ser utilizado como bioindicador de exposição e toxicidade em zonas agrícolas. Para atingir este objectivo, utilizámos uma estratégia integrada com três fases. Numa primeira fase realizou-se um estudo de campo para documentar o tipo de exposição e parâmetros populacionais de populações de lacertídeos que ocorrem em zonas de uso intenso de pesticidas e zonas de agricultura orgânica. A segunda fase consistiu num estudo de mesocosmo em que se expuseram juvenis a um conjunto de pesticidas em condições controladas durante um período de um ano. Finalmente, a terceira fase incluiu um estudo laboratorial sobre os efeitos do clorpirifos, um dos insecticidas mais utilizado a nível global, em lagartixas. No término de cada um dos estudos, analisaram-se diversos biomarcadores e parâmetros de exposição e toxicidade a pesticidas nos diferentes indivíduos. Este conjunto abrangente de parâmetros foi analisado em diferentes níveis de organização biológica, incluindo parâmetros populacionais, bem como comportamentais, fisiológicos, bioquímicos e histológicos. Em geral, detectaram-se poucas diferenças estatísticas significativas entre as populações dos campos expostos a pesticidas e populações referência. Confirmando a dificuldade que existe em isolar os efeitos de diferentes contaminantes sobre as populações de outros factores locais, ciclos sazonais ou eventos estocásticos. As populações de P. bocagei parecem ser capazes de lidar com o nível observado de exposição a pesticidas. No entanto, indivíduos que vivem em locais expostos a pesticidas parecem estar menos adaptados ecologicamente do que aqueles que vivem em locais referência, apresentando um estado de depleção nutricional e sinais de stress metabólico. Os resultados obtidos com os animais da experiência de mesocosmo parecem reforçar estes resultados. Os animais prosperaram relativamente bem em todos os mesocosmos, independentemente do tratamento ou não com pesticidas, apresentando uma ampla gama de comportamentos naturais. A abordagem laboratorial confirmou P. bocagei como um valioso indicador de exposição sub-letal a doses ambientalmente realistas de clorpirifos. De acordo, com o conjunto d resultados obtidos, P. bocagei parece ser um bioindicador adequado de exposição a pesticidas.

The reception of British literature under dictatorships in Hungary and Portugal

Esta tese tem como objectivo comparar aspectos da recepção da literatura britânica durante o Estado Novo em Portugal, e na Hungria durante a era comunista. Na primeira parte da dissertação fica contextualizada e analisada a alteração da posição da literatura britânica nos dois países, enquanto na segunda parte se comparam facetas da recepção da mesma, contrastando as traduções literárias publicadas em Portugal e na Hungria entre 1949 e 1974, altura em que ambos os países foram dirigidos simultaneamente por regimes autocratas. Este estudo faz-se, em parte, através da comparação de manuais escolares e seletas, a fim de examinar os diferentes métodos usados pelos dois regimes ditatoriais politicamente opostos na tentativa de moldarem os seus leitores. É dada especial atenção à literatura proibida e aos motivos para as atitudes restritivas diferenciadas em relação a certos escritores na era de Salazar e na Hungria durante o período de Bloco de Leste. A tese conclui que a abordagem divergente em relação às obras literárias britânicas, bem como à literatura em geral, é principalmente enraizada na ideologia de governação diametralmente oposta dos dois regimes ditatoriais. A crença idealista no poder educativo da literatura em estabelecer o socialismo na Hungria está em nítido contraste com a política de cultura obscurantista do Estado Novo. Mesmo quando o apoio à literatura britânica não era uma das principais prioridades da esfera cultural húngara, parece evidente que a literatura canónica britânica teve uma recepção mais favorável na Hungria comunista do que no Estado Novo.

Mining biomedical information from scientific literature

The rapid evolution and proliferation of a world-wide computerized network, the Internet, resulted in an overwhelming and constantly growing amount of publicly available data and information, a fact that was also verified in biomedicine. However, the lack of structure of textual data inhibits its direct processing by computational solutions. Information extraction is the task of text mining that intends to automatically collect information from unstructured text data sources. The goal of the work described in this thesis was to build innovative solutions for biomedical information extraction from scientific literature, through the development of simple software artifacts for developers and biocurators, delivering more accurate, usable and faster results. We started by tackling named entity recognition - a crucial initial task - with the development of Gimli, a machine-learning-based solution that follows an incremental approach to optimize extracted linguistic characteristics for each concept type. Afterwards, Totum was built to harmonize concept names provided by heterogeneous systems, delivering a robust solution with improved performance results. Such approach takes advantage of heterogenous corpora to deliver cross-corpus harmonization that is not constrained to specific characteristics. Since previous solutions do not provide links to knowledge bases, Neji was built to streamline the development of complex and custom solutions for biomedical concept name recognition and normalization. This was achieved through a modular and flexible framework focused on speed and performance, integrating a large amount of processing modules optimized for the biomedical domain. To offer on-demand heterogenous biomedical concept identification, we developed BeCAS, a web application, service and widget. We also tackled relation mining by developing TrigNER, a machine-learning-based solution for biomedical event trigger recognition, which applies an automatic algorithm to obtain the best linguistic features and model parameters for each event type. Finally, in order to assist biocurators, Egas was developed to support rapid, interactive and real-time collaborative curation of biomedical documents, through manual and automatic in-line annotation of concepts and relations. Overall, the research work presented in this thesis contributed to a more accurate update of current biomedical knowledge bases, towards improved hypothesis generation and knowledge discovery.

A definition of literary literacy: a content analysis of literature syllabuses and interviews with Portuguese lecturers of literature

The aim of this paper is to present a definition of literary literacy in the context of majors in languages, literatures and cultures, in Portugal. A definition of literary literacy was deduced from a content analysis of primary data sources and from the theoretical underpinnings of the transactional theory of reading. The primary data sources are fourteen Portuguese and English literature syllabuses from four Portuguese universities (Lisboa, Nova, Coimbra and Porto) and twelve interviews with Portuguese university lecturers of literature. Based on the findings of a content analysis of both syllabuses and interviews, from the lecturers‘ point of view, a literary literate student doing a major in languages, literatures and cultures must, above all, be able to contextualize literary texts and their authors both historically and culturally, must be able to present an interpretation as a coherent text, and must be able to do and organize bibliographical research.

Study of sewage sludge aimed at agricultural soil amendment by thermogravimetric analysis and fourier-transform infrared spectroscopy

Thermal degradation and gaseous products evolving from the pyrolysis of sewage sludge, aimed at agricultural soil amendment, were investigated using Thermogravimetric Analysis in conjunction with Fourier Transform Infrared Analysis (TG-FTIR). The materials were studied in temperatures ranging from 30 to 800 ºC. Furthermore infrared spectra of sewage sludge samples were performed as a complementary technique. In parallel the sewage sludge was spiked with ibuprofen in order to test whether the mentioned techniques are able to detect the drug. Thermal analysis showed the range of 200-400ºC as the most characteristic for weight loss, corresponding with the organic matter volatilization, while the range of 500-800ºC was also characteristic and due to the volatilization of carbonates. On the other hand, ibuprofen-spiking tests identified at temperature range (150-250ºC) where the compound totally volatilizes, therefore, in this work, the detection of ibuprofen by TGA was established for concentrations higher than 0.5 g/kg sludge, concentration 102 times higher than the concentrations measured by other authors in regular sewage sludge (Martín, et al., 2010). A correlation has been found between the ibuprofen concentrations in the sludge and the intensity of the absorption bands, both for FT-IR spectra at the maximum emission temperature for ibuprofen (232ºC) as for the FT-IR spectra of the non-pyrolyzed samples.

The economic effects of common agricultural policy on Mediterranean montado/dehesa ecosystem

The decoupling of CAP payments leads production decisions and resources allocation to be more dependent on market prices and competitive advantages. The objective of this paper is to assess the effects of CAP trends on the montado/dehesa traditional ecosystem of Mediterranean regions in terms of farm income, land, labour and capital. A positive mathematical supply model disaggregated by the montado agro-forestry production systems of the Alentejo region in southern Portugal is developed. The results show that decoupling payments of CAP have negative economic effects on agricultural activities and resource use. Agricultural income increases with single farm payments but the foreseen increases in prices do not compensate the loss of the Agenda 2000 area payments in terms of competitiveness. These results reinforce the need to promote alternative agricultural and non-agricultural activities and policies in Mediterranean rural European areas and regions.

Is agricultural policy promoting a new role for farmers?: a case study

European Agenda 2000 considers the integration of environment in CAP and the role farmers can play on natural resources management. Alternative tillage technologies to seed cereals play an important economic and environmental role on the development of a sustainable agriculture and its adoption may depend on the agricultural policy, particularly policies on income support. The results obtained clearly show that the use of alternative soil tillage technologies would be promoted by the change of supports from the first to the second pillar of CAP and we can conclude that, in general, this change will encourage a faster technological adoption.

Combined disaggregation of agricultural land uses, livestock numbers and crops' production: an entropy approach

This paper presents several combined agricultural data disaggregation models in order to recover the farms' land uses, the livestock numbers and main crops' productions. The proposed approach estimates incomplete information at disaggregated level through entropy, using an information prior, and generating information for a combined calculation use of data in the estimation of other variables. The models were applied to the region of Algarve, to some rural pilot areas (Salir-Ameixial-Cachopo and Alcoutim) for livestock data, since this data in some Algarve's inland areas is needed for a European forest fire prevention project, and to the agrarian zones in a more complex framework. The results are promising. They were validated, in cross reference to real data, having proven to be valid and reliable. The total error was small and a considerable level of information heterogeneity was recovered. The total error was about 27,9% for the counties' land uses and 21% for the agrarian zones, and for the livestock it was also acceptable. The level of heterogeneity recovered was always higher than 50%, revealing some improvements regarding previous studies.
