The Exodus evacuation model applied to building evacuation scenarios

The purpose of this paper is to demonstrate the potential of the EXODUS evacuation model in building environments. The latest PC/workstation version of EXODUS is described and is also applied to a large hypothetical supermarket/restaurant complex measuring 50 m x 40 m. A range of scenarios is presented where population characteristics (such as size, individual travel speeds, and individual response times), and enclosure configuration characteristics (such as number of exits, size of exits, and opening times of exits) are varied. The results demonstrate a wide range of occupant behavior including overtaking, queuing, redirection, and conflict avoidance. Evacuation performance is measured by a number of model predicted parameters including individual exit flow rates, overall evacuation flow rates, total evacuation time, average evacuation time per occupant, average travel distance, and average wait time. The simulations highlight the profound impact that variations in individual travel speeds and occupant response times have in determining the overall evacuation performance. 1.

Una revisión de la Cadena Datos-Información-Conocimiento desde el Pragmatismo de Peirce

La Cadena Datos-Información-Conocimiento (DIC), denominada “Jerarquía de la Información” o “Pirámide del Conocimiento”, es uno de los modelos más importantes en la Gestión de la Información y la Gestión del Conocimiento. Por lo general, la estructuración de la cadena se ha ido definiendo como una arquitectura en la que cada elemento se levanta sobre el elemento inmediatamente inferior; sin embargo no existe un consenso en la definición de los elementos, ni acerca de los procesos que transforman un elemento de un nivel a uno del siguiente nivel. En este artículo se realiza una revisión de la Cadena Datos-Información-Conocimiento examinando las definiciones más relevantes sobre sus elementos y sobre su articulación en la literatura, para sintetizar las acepciones más comunes. Se analizan los elementos de la Cadena DIC desde la semiótica de Peirce; enfoque que nos permite aclarar los significados e identificar las diferencias, las relaciones y los roles que desempeñan en la cadena desde el punto de vista del pragmatismo. Finalmente se propone una definición de la Cadena DIC apoyada en las categorías triádicas de signos y la semiosis ilimitada de Peirce, los niveles de sistemas de signos de Stamper y las metáforas de Zeleny.

Information sharing and reporting systems in the UK and Ireland: Professional barriers to reporting child maltreatment concerns

Across the UK recent policy developments have focused on improved information sharing and inter-agency cooperation. Professional non-reporting of child maltreatment concerns has been consistently highlighted as a problem in a range of countries and the research literature indicates that this can happen for a variety of reasons. Characteristics such as the type of abuse and the threshold of evidence available are key factors, as are concerns that reporting will damage the professional-client relationship. Professional discipline can also impact on willingness to report, as can personal beliefs about abuse, attitudes towards child protection services and experiences of court processes. Research examining the role of organisational factors in information sharing and reporting emphasises the importance of training and there are some positive indications that training can increase professional awareness of reporting processes and requirements and help to increase knowledge of child abuse and its symptoms. Nonetheless, this is a complex issue and the need for training to go beyond simple awareness raising is recognised. In order to tackle non-reporting in a meaningful way, childcare professionals need access to on-going multidisciplinary training which is specifically tailored to address the range of different factors which impact on reporting attitudes and behaviours.

Linking Parliamentary Records through Metatdata

The LIPARM schema links the parliamentary record together for the first time by creating a unified metadata scheme for all of its key elements. People, bills, acts, items of business, debates, divisions and sessions will all be described by the scheme and will be linked together across resources which are currently spread out and isolated. For the first time, it will be possible to trace a given MP’s entire voting record or to find every speech they made. It will be possible to follow the passage of every bill or act, and every contribution to the debates that accompany it. Both the historical and the contemporary record of parliamentary proceedings will become accessible in this way for the first time.

Re-embedding economic and social constitutionalism:Normative perspectives for the EU

Introduction Tensions between the economic and the social dimensions of European integration are being perceived as increasing, and so is the potential for conflict between national and European levels of policy-making. Both are well illustrated by a highly controversial line of Court of Justice of the European Union (ECJ) cases on industrial relations: Viking and Laval have become symbols for the continuing dominance of the economic over the social dimension of European integration and for an increasing tendency of the EU to diminish national autonomy. As one consequence, demands to protect Member States’ social policy choices from EU law pressures arise. For such demands to be tenable, isolation of national and EU policy-making and of economic and social dimensions of European integration would have to be possible. This is arguably not the case. Economic and social dimensions of integration will thus have to be reconciled across EU and national levels, if the EU and its Member States are to maintain the ability of enhancing social justice against the pulls of economic globalisation.

Employee 'words' on high involvement work practices, value congruence and burnout

This article examined the impact of perceived high involvement work practices (HIWPs) on person-organization value congruence (P-O fit) and long term burnout. The study was conducted in a Canadian general hospital. Findings from structural equation modeling (N = 185) revealed that perceived HIWPs were significantly positively associated with P-O fit. While there was no direct effect of HIWPs on burnout, P-O fit fully mediated the relationship between perceptions of HIWPs and burnout. We discuss the implications of these findings for our understanding of HIWPs influence on P-O fit and burnout.

Non-invasive ventilation for cystic fibrosis.

Non-invasive ventilation may be a means to temporarily reverse or slow the progression of respiratory failure in cystic fibrosis. To compare the effect of non-invasive ventilation versus no non-invasive ventilation in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches, handsearching relevant journals and abstract books of conference proceedings. We searched the reference lists of each trial for additional publications possibly containing other trials.Most recent search: 22 February 2013. Randomised controlled trials comparing a form of pressure preset or volume preset non-invasive ventilation to no non-invasive ventilation in people with acute or chronic respiratory failure in cystic fibrosis. Three reviewers independently assessed trials for inclusion criteria and methodological quality, and extracted data. Fifteen trials were identified; seven trials met the inclusion criteria with a total of 106 participants. Six trials evaluated single treatment sessions and one evaluated a six-week intervention.Four trials (79 participants) evaluated non-invasive ventilation for airway clearance compared with an alternative chest physiotherapy method and showed that airway clearance may be easier with non-invasive ventilation and people with cystic fibrosis may prefer it. We were unable to find any evidence that NIV increases sputum expectoration, but it did improve some lung function parameters.Three trials (27 participants) evaluated non-invasive ventilation for overnight ventilatory support, measuring lung function, validated quality of life scores and nocturnal transcutaneous carbon dioxide. Due to the small numbers of participants and statistical issues, there were discrepancies in the results between the RevMan and the original trial analyses. No clear differences were found between non-invasive ventilation compared with oxygen or room air except for exercise performance, which significantly improved with non-invasive ventilation compared to room air over six weeks. Non-invasive ventilation may be a useful adjunct to other airway clearance techniques, particularly in people with cystic fibrosis who have difficulty expectorating sputum. Non-invasive ventilation, used in addition to oxygen, may improve gas exchange during sleep to a greater extent than oxygen therapy alone in moderate to severe disease. These benefits of non-invasive ventilation have largely been demonstrated in single treatment sessions with small numbers of participants. The impact of this therapy on pulmonary exacerbations and disease progression remain unclear. There is a need for long-term randomised controlled trials which are adequately powered to determine the clinical effects of non-invasive ventilation in cystic fibrosis airway clearance and exercise.

Eco-efficiency approaches towards a sustainable composite materials manufacturing industry’

In this study the potential eco-efficiency performance of a pultrusion manufacturing company was assessed. Indicators values and eco-efficiency ratios were estimated taking into account the implementation of new proceedings and procedures in the production process of glass fibre reinforced polymers (GFRP) pultrusion profiles. Two different approaches were foreseen: 1)Adoption of a new heating system for pultrusion die in the manufacturing process, more effective and with minor heat losses; and 2) Recycling approach, with partial waste reuse of scrap material derived from manufacturing, cutting and assembly processes of GFRP profiles. These features lead to significant improvements on the sequent assessed eco-efficiency ratios of the present case study, yielding to a more sustainable product and manufacturing process of pultruded GFRP profiles.

Intervenção em situações de violência e indisciplina em alunos do ensino básico: Estudo de Caso

A indisciplina e a violência em contexto escolar têm sido uma preocupação social crescente e um assunto amplamente discutido sob diversas perspetivas. Pela complexidade de que se revestem e amplitude de implicações que acarretam, nomeadamente o insucesso escolar e as consequências psicossociais e individuais inerentes, os problemas ao nível do comportamento exigem cada vez mais uma resposta eficaz da comunidade escolar, que vê o seu funcionamento diário ser prejudicado. A acumulação de processos disciplinares evidencia a ineficácia dos sistemas punitivos, pelo que se impõe uma alternativa eficaz. Neste trabalho procuramos apresentar um programa de intervenção comportamental de caráter preventivo e que tem revelado eficácia em diversos contextos escolares. Pelo seu carácter proativo e cientificamente fundamentado, o sistema PBIS (Positive Behavioral Interventions and Supports) apoia-se em princípios da Psicologia Positiva e em dados empíricos e oferece um quadro operacional adaptável a qualquer instituição escolar. O estudo de caso apresentado apresenta intervenções de nível dois e três que, mesmo sem a implementação do nível um de base, revelaram resultados bastante positivos, pelo que há evidências de que seria benéfico para as escolas a introdução destes sistemas no combate diário, constante e preocupante à indisciplina.

A Metrologia na Indústria Aeronáutica

O presente relatório é um dos elementos que contribuirão para a concretização da avaliação individual da Unidade Curricular de Dissertação/Projeto/Estágio Profissional, inserida no plano de estudos do Mestrado em Engenharia de Instrumentação e Metrologia e traduz o trabalho realizado na empresa Caetano Aeronautic. O estágio, com a duração de sete meses, permitiu a concretização de finalidades e objetivos que deram suporte ao desenvolvimento das aprendizagens e mobilização dos saberes científicos relativos a domínios e conteúdos curriculares, nomeadamente inseridos nas áreas da Metrologia e Qualidade. A Metrologia é circunscrita como a ciência da medição. A medição é uma operação de extrema relevância em diversas atividades, porque é através da Metrologia que se garante um elevado nível de qualidade pretendido para a conceção, fabricação e utilização de serviços ou produtos. Face à indústria aeronáutica envolver um elevado conjunto de processos, de normas e documentação, foi necessário inicialmente um envolvimento integrado com o Sistema de Gestão da Qualidade da Caetano Aeronautic e com as operações inerentes, nomeadamente de melhoria contínua. Foram desenvolvidas, dentro do possível, propostas de melhoria no processo de inspeção dos componentes aeronáuticos. Dentro das mesmas destacam-se a alteração dos registos de medição, o estudo e posterior proposta de aquisição de ferramentas adicionais para equipamentos de medição. O fluxo de medição tornou-se mais fluído através da concretização da proposta de alteração do layout do laboratório. De salientar o trabalho desenvolvido na área da Engenharia da Qualidade, nomeadamente no tratamento de não conformidades, o que contribuiu para que o processo se encontre atualmente bastante simplificado na empresa.

A caracterização do trabalho análogo ao escravo na jurisprudência dos tribunais brasileiros

Based on bibliographical research and the analysis of court rulings, this study investigates the characterization of slave-like labor by Brazilian courts. After the alteration of article 149 of the Brazilian Penal Code, introduced by Law nº 10.803/2003, which typifies the practice of contemporary slavery in Brazil, divergent characterizations of this practice remain. The courts currently employ the broadest concept of contemporary slave labor, in which the crime is characterized by the engagement in one of the following conducts established as a criminal offense: labor with the restriction of freedom, submission to exhaustive working conditions, degrading working conditions, and debt bondage. The engagement in one of the above is therefore enough to constitute a crime. Contemporary slave labor in Brazil is not characterized only by the restriction of the worker’s freedom, as in the case of forced labor or debt bondage, but also through the submission of the workers to situations that offend their human dignity. Individual freedom and the dignity of the human person, fundamental tenets of the Brazilian Federal Constitution, are juridical resources safeguarded by law. Contemporary slavery is not limited to the mere infringement of labor laws, but represents a severe violation of the human rights of the workers involved.
