Counsellors working with students or other young adults may encounter individuals who have self-harmed, either with suicidal or non-suicidal intent. Recent US studies reported rates of self-injury of up to 37% of the student population, but studies in the UK have focussed primarily on younger adolescents. This study examined reported self-harm incidents (scratching, cutting, poisoning, overdose etc) from a sample of 617 university students. A total of 27% reported at least one incident of self-harm, with almost 10% having harmed themselves while at university. Gender differences were not significant but psychology students reported significantly more self-harm than other students. Participants reporting self-harm scored significantly higher on maladaptive coping styles, rumination, and alexithymia (specifically difficulty in identifying emotions) and these differences were most marked for students reporting repetitive and recent self-harm. Rumination and Alexithymia factor 1 (difficulty identifying feelings) emerged as the most robust factors predicting self-harm status. Comments from students who self-harmed at university highlighted the importance of accessible services and academic staff support. The implications of these findings for counselling interventions are discussed, including challenging negative rumination tendencies and developing mindfulness skills.

The current study sought to explore the impact of suicidal behaviours on probation staff, in relation to their experiences of working with probation service users who have carried out suicide, attempted suicide or self-harm. Thirteen in-depth interviews were carried out with probation staff who had direct contact with probation service users in one probation area, and had varying degrees of experience of managing suicidal or self-injurious service users. These were analysed using thematic analysis and five themes were identified. Findings indicate that staff felt that suicide and self-harm by service users are serious issues which need to be recognized and dealt with in an effective yet compassionate manner. Not attending the suicide prevention training, or lack of experience, were perceived as restricting their ability to know how to deal with these individuals, and offer support. Furthermore, staff were emotionally affected by these incidents and it is recommended that they should continue to be provided with access to appropriate support services after an incident.

Recent research on WW1 shows that incidents of fraternization across enemy lines took place regularly. However, fraternization remains a taboo in many contexts. The fact that the 2005 film Joyeux Noel by Christian Caron, which explicitly deals with the subject, encountered resistance from the authorities, is an indication of the kind of difficulty associated with the issue. I am drawing my inspiration from the way fraternizations are depicted in the film and in the literature in order to explore the concept of spatial justice. I define spatial justice as the question that emerges when a body desires to occupy the same space at the same time as another body. Defined like this, the question of spatial justice opens up in the dread of No Man’s Land and in particular the exchange of affects, objects and narratives that went on during fraternizations. I trace the movement of spatial justice as one of withdrawal from the asphyxiating atmosphere of the war and the propaganda machine. This withdrawal is not one of unpatriotic stance but of a courageous and difficult detachment from the supposed legality of the war that could only function on the basis of hate and demonization. While fraternizations did not end the war, they allowed for the possibility of spatial justice to emerge, as an opportunity to reorient the space and the bodies within.

The activity of Control Center operators is important to guarantee the effective performance of Power Systems. Operators’ actions are crucial to deal with incidents, especially severe faults like blackouts. In this paper, we present an Intelligent Tutoring approach for training Portuguese Control Center operators in tasks like incident analysis and diagnosis, and service restoration of Power Systems. Intelligent Tutoring System (ITS) approach is used in the training of the operators, having into account context awareness and the unobtrusive integration in the working environment. Several Artificial Intelligence techniques were criteriously used and combined together to obtain an effective Intelligent Tutoring environment, namely Multiagent Systems, Neural Networks, Constraint-based Modeling, Intelligent Planning, Knowledge Representation, Expert Systems, User Modeling, and Intelligent User Interfaces.

As obras subterrâneas têm actualmente maior relevância, sobretudo em meios urbanos e são, desde a fase de estudo até à sua execução, projectos tecnicamente complexos, exigentes e interessantes. O meio em que a obra subterrânea está inserida condiciona, quer na fase de estudo quer no desenvolvimento dos trabalhos, as opções técnicas e representa um desafio constante para todos os intervenientes. São poucos os técnicos que têm a oportunidade de acompanhar e apreender o conhecimento envolvido nestas obras, pelo que é importante que toda a experiência adquirida seja registada e se possível transmitida. Pela sua formação e vocação, os engenheiros geotécnicos desempenham um papel de destaque nestes empreendimentos, onde o conhecimento e a sensibilidade técnica, associados à experiência em trabalhos semelhantes, são factores determinantes para atingir os objectivos propostos. Com este trabalho pretende-se caracterizar, valorizar, analisar e concluir sobre as várias etapas desenvolvidas na construção do túnel de Seixo Alvo, enquadrado na Concessão do Douro Litoral. Realizou-se uma apreciação do estado da arte e apresenta-se o túnel do Seixo Alvo como caso de estudo, onde se evidencia a importância do estudo e observação da obra e do meio em que está inserida, caracteriza os métodos e processos construtivos implementados e propostos, analisa os incidentes ocorridos e valoriza os trabalhos executados. Por último conclui-se sobre as técnicas, os custos e os rendimentos obtidos.

1.Pre-assessment data of the patient A 2-year-old boy, weighing 15 kg was admitted with a history of limited mouth opening(inter-incisor distance of 6 mm), hypoplastic and retrognathic mandible (bird face deformity) and facial asymmetry from left temporomandibular joint ankylosis (TMJA). He was born at term, after an uneventful pregnancy, and there was no report of trauma during caesarean section. No other possible aetiologies were identified. He was scheduled for mandibular osteotomy. Preoperative ENT examination revealed adenotonsillar hypertrophy. 2. Anaesthetic Plan A fiberoptic nasal intubation was performed under deep inhalation anaesthesia with sevoflurane, with the patient breathing spontaneously. Midazolam (0.05 mg.kg-1) and alfentanil (0.03 mg.kg-1) were given and anaesthesia was maintained with O2/air and sevoflurane. No neuromuscular blocking agent was administered since the surgical team needed facial nerve monitoring. 3. Description of incident During surgery an accidental extubation occurred and an attempt was made to reintubate the trachea by direct laryngoscopy. Although the osteotomy was nearly completed, the vocal cords could not be visualized (Cormack-Lehane grade IV laryngoscopic view). 4. Solving the problem Re-intubation was finally accomplished with the flexible fiberscope and the procedure was concluded without any more incidents. Extubation was performed 24 hours postoperatively with the patient fully awake. After surgery mouth opening improved to inter-incisor gap of 15 mm. 5. Lessons learned and take home message Two airways issues present in this case can lead to difficultventilation and intubation: TMJA and adenotonsillar hypertrophy. These difficulties were anticipated and managed accordingly. The accidental extubation brought to our attention the fact that, even after surgical correction, this airway remains challenging. Even with intensive jaw stretchingexercises there is a high incidence of re-ankylosis, especially in younger patients. One should bear that in mind when anaesthetizing patients with TMJA.

A instabilização de taludes rochosos, com consequências mais ou menos gravosas, repete-se com frequência no território nacional. Os enquadramentos destes incidentes são diversos, sendo mais comum e mais visível a sua ocorrência em taludes adjacentes a vias de comunicação. No entanto, o fenómeno repete-se também em vertentes naturais, geralmente em alturas de pluviosidade mais prolongada e intensa. No presente trabalho reveem-se conceitos associados a maciços rochosos, nomeadamente as principais classificações geotécnicas e as diferentes tipologias de instabilidade em taludes rochosos. Desenvolve-se um caso de estudo de uma vertente localizada em S. Simão, concelho de Amarante. Percorrem-se as sucessivas fases de estudo, incluindo a realização da fotografia aérea com recurso a um veículo não tripulado, a geração de um modelo 3D de elevada precisão da vertente e a caracterização e a classificação dos diferentes afloramentos rochosos. Desenvolve-se uma metodologia de inspeção com a criação de dois conjuntos de fichas e propõe-se o agravamento da classificação das anomalias perante a simultaneidade de ocorrência de anomalias de idêntica gravidade e a hierarquização dos blocos potencialmente instáveis, de acordo com os respetivos níveis de gravidade (NGB). Recorre-se ao programa de modelação da queda de blocos, “Rocfall (4.0”, da “Rocscience”, a partir de trajetórias definidas no modelo 3D gerado e propõem-se soluções de reforço e de proteção da vertente.

RESUMO - O problema do erro de medicação tem vindo a adquirir uma importância e um interesse crescentes nos últimos anos. As consequências directas no doente que condicionam frequentemente o prolongamento do internamento, a necessidade de utilização adicional de recursos e a diminuição de satisfação por parte dos doentes, são alguns dos aspectos que importa analisar no sentido de se aumentar a segurança do doente. No circuito do medicamento em meio hospitalar estão envolvidos diversos profissionais, estando o enfermeiro no final da cadeia quando administra a medicação ao doente. Na bibliografia internacional, são referidas incidências elevadas de eventos adversos relacionados com o medicamento. Em Portugal, não existem estudos disponíveis que nos permitam conhecer, nem o tipo de incidentes, nem a dimensão do problema do erro de medicação. Efectuamos um estudo descritivo, prospectivo, exploratório, utilizando a técnica de observação não participante, da administração de medicamentos. Os objectivos são, por um lado, determinar a frequência de incidentes na administração de medicação num Serviço de Medicina Interna e, por outro, caracterizar o tipo de incidentes na administração da medicação e identificar as suas possíveis causas. A população em estudo foi constituída pelos enfermeiros que administraram medicamentos aos doentes internados no Serviço de Medicina Interna seleccionado, durante os meses de junho a agosto de 2012, sendo observadas 1521 administrações. Foi utilizada uma grelha de observação, que incluiu os seguintes elementos: doente certo; medicamento certo; dose certa; hora certa; via certa; técnica de administração correcta (assépsia); tempo de infusão; monitorização correcta. Constatou-se que em 43% das doses administradas apresentavam pelo menos um erro, num total de 764 erros. Não foi observado nenhum erro de doente, de medicamento, de dose extra, de via, de forma farmacêutica, nem a administração de medicamento não prescrito. Detectaram-se 0,19% de erros na preparação, 0,72% de erros de dose, 1,7% erros de omissão, 1,97% de erros de administração, 13,52% de erros de monitorização, 28,73% de erros de v horário. O tempo de infusão da terapêutica parentérica não foi cumprida em 27,69% das oportunidades, tendo sido sempre administrado em tempo inferior ao preconizado. Não encontramos relação entre as interrupções durante a administração de terapêutica e os erros. Pelo contrário constatou-se haver relação entre o número de doses com erro e o turno em que ocorreram, sendo mais frequentes no turno da noite. Constatamos também que aos fins de semana os erros eram mais frequentes e o risco da ocorrência de um erro na administração de medicação aumenta 1,5 vezes quando o número de enfermeiros é insuficiente.

A producer of 5.4 M bbl/d, totalling almost half of the consumption of the entire European Union, the Gulf of Guinea is a fundamental lifeline and maritime link between Europe, the Americas and Africa. Geographically positioned as a staging post for transit originating in Latin America and coupled with its relatively porous borders, the region is also the perfect stepping stone for contraband heading to European shores. While blessed with an enviable wealth of marine and mineral resources, the region is also plagued by an ever-increasing spectre of maritime piracy; accounting for around 30% of incidents in African waters from 2003 to 2011. It is for these reasons that this research centres around the issues of maritime security in the Gulf of Guinea, with a particular focus on the first two decades of the 21st century. This research looks to examine the overall picture of the present state of play in the area, before going on to provide an analysis of potential regional developments in maritime security. This research begins with the analysis of concepts/phenomena that have played a notable role in the shaping of the field of maritime security, namely Globalisation and security issues in the post-Cold War era. The ensuing chapter then focuses in on the Gulf of Guinea and the issues dominating the field of maritime security in the region. The penultimate chapter presents a SWOT analysis, undertaken as part of this research with the aim of correlating opinions from a variety of sectors/professions regarding maritime security in the Gulf of Guinea. The final chapter builds upon the results obtained from the abovementioned SWOT analysis, presenting a series of potential proposals/strategies that can contribute to the field of maritime security in the region over the coming years. This research draws to a close with the presentation of conclusions taken from this particular investigation, as well as a final overview of the earlier presented proposals applicable to the field of maritime security during the second decade of the 21st century.
