Hyperkalaemia, an elevated extracellular fluid potassium concentration, is a common electrolyte disorder and is present in 1-10% of hospitalised patients. Elevated serum potassium concentrations are usually asymptomatic but may be associated with electrocardiogram (ECG) changes. Hyperkalaemia occasionally leads to life-threatening cardiac arrhythmias. Prompt recognition of this disorder, patient risk management and administration of appropriate treatment can prevent serious cardiac complications of hyperkalaemia. Further assessment of the underlying basis for hyperkalaemia usually reveals a problem with renal potassium excretion (rather than transcellular shift of potassium or excess potassium intake). Reduced potassium excretion is typically associated with decreased potassium secretion in the aldosterone-sensitive distal nephron of the kidney. Common causes for hyperkalaemia include kidney failure, limited delivery of sodium and water to the distal nephron and drugs that inhibit the renin-angiotensin-aldosterone system. Treatment of life-threatening hyperkalaemia (particularly those patients with ECG changes) involves administration of intravenous calcium salts to stabilise the resting cardiac membrane potential. The potassium concentration can be lowered by administration of intravenous insulin combined with an infusion of glucose to stimulate intracellular uptake of potassium. Nebulised β-2 adrenoceptor agonists can augment the effects of intravenous insulin and glucose pending more definitive management of the recurrent hyperkalaemia risk. Additional management steps include stopping further potassium intake and careful review of prescribed drugs that may be adversely affecting potassium homeostasis. Changes to prescribing systems and an agreed institutional protocol for management of hyperkalaemia can improve patient safety for this frequently encountered electrolyte disorder.

Past research has frequently attributed the incidence of bank failures to macroeconomic cycles and/or downturns in the regional economy. More recent analyses have suggested that the incidence and severity of bank failures can be linked to governance failures, which may be preventable through more stringent disclosure and auditing requirements. Using data on bank failures during the years 1991 to 1997, for the US, Canada, the UK and Germany, this study examines the relationship between institutional characteristics of national legal and auditing systems and the incidence of bank failures. In the second part of our analysis we then examined the relationship between the same institutional variables and the severity of bank failures.
The first part of our study notes a significant correlation between the law and order tradition (‘rule of law’) of a national legal system and the incidence of bank failures. Nations which were assigned high 'rule of law’ scores by country risk guides appear to have been less likely to experience bank failures. Another variable which appears to impact on bank failure rates is the ‘risk of contract repudiation’. Countries with a greater ‘risk of contract repudiation’ appear to be more likely to experience bank failures. We suggest that this may be due to a greater ex ante protection of stakeholders in countries where contract enforcement is more stringent.
The results of the second part of our study are less clear cut. However, there appears to be a significant correlation between the amount paid out by national deposit insurers (our proxy for the severity of bank failures) and the macroeconomic variable 'GDP change'. Here our findings follow the conventional wisdom; with greater amounts of deposit insurance funds being paid during economic downturns (i.e. low or negative GDP 'growth' correlates with high amounts of deposit insurance being paid out). A less pronounced relationship with the severity of bank failures can also be established for the institutional variables ' accounting standards' as well as 'risk of contract repudiation'. Countries with more stringent ‘accounting standards’ and a low ‘risk of contract repudiation’ appear to have been less prone to severe bank failures.

Food colours are added to different types of commodities to increase their visual attractiveness or to compensate for natural colour variations. The use of these additives is strictly regulated in the European Union, the United States and many other countries worldwide. There is a growing concern about the safety of some commonly used legal food colourants and there is a trend to replace the synthetic forms with natural products. Additionally, a number of dyes with known or suspected genotoxic or carcinogenic properties have been shown to be added illegally to foods. Robust monitoring programs based on reliable detection methods are required to assure the food is free from harmful colours. The aim of this review is to present an up to date status of the various concerns arising from use of colour additives in food. The most important food safety concerns in the field of food colours are lack of uniform regulation concerning legal food colours worldwide, possible link of artificial colours to hyperactive behaviour, replacement of synthetic colours with natural ones and the presence of harmful illegal dyes - both known but also new, emerging ones in food. The legal status of food colour additives in the EU, US and worldwide is summarized. The reported negative health effects of both legal and illegal colours are presented. The European Rapid Alert System for Food and Feed notifications and US import alerts concerning food colours are analyzed and trends in fraudulent use of colour additives identified. The detection methods for synthetic colours are also reviewed.

À medida que a supervisão, associada a lógicas de interação com a atividade docente e com outros intervenientes nos contextos educativos, adquiriu uma dimensão reflexiva e passou a ser entendida como instrumento de transformação do desenvolvimento humano e da qualidade do processo de ensino e aprendizagem na organização escolar inclusiva, tem vindo a conquistar o interesse de numerosos investigadores. Considerando que a intenção de oferecer uma escola de qualidade a todos e a cada um dos alunos (um dos princípios fundamentais da educação inclusiva), não está amplamente atingido, impõe-se uma nova atitude pessoal e institucional: um entendimento sistémico (envolvendo profissionais, alunos, pais e comunidade) sobre as respostas a oferecer aos alunos, capaz de atender às necessidades e especificidades de cada um, otimizando as suas oportunidades de aprendizagem e desenvolvimento. Na verdade, a intervenção na complexidade das diferentes situações-problema emergentes numa organização escola que se pretende inclusiva pode ser altamente potenciada se existir supervisão dos processos educacionais em curso. A especificidade do sistema de Educação Especial preconiza uma estrutura de coordenação e supervisão; uma estrutura capaz de viabilizar recursos e gerar dinâmicas de mediação à intervenção, bem como de acionar mecanismos de avaliação de processos e produtos, tornando-os consequentes ao nível das práticas e objetivando a aproximação a níveis superiores de funcionamento. Tendo como principal objetivo construir conhecimento sobre o perfil de competências profissionais do Coordenador da Educação Especial, com particular relevo na dimensão supervisiva inerente à respetiva ação, o estudo que se apresenta baseou-se numa abordagem de natureza mista para recolha e tratamento de dados de tipo quantitativo e qualitativo. Numa primeira fase, incluiu a aplicação dum inquérito por questionário a três grupos de informantes-chave: 105 professores de Educação Especial, 47 coordenadores da Educação Especial e 37 diretores de agrupamentos de escolas/escolas não agrupadas, do ensino público, da área de influência da Direção de Serviços da Região Centro, Direção-Geral dos Estabelecimentos Escolares. A segunda fase, em que se buscou vislumbrar insights passíveis de clarificar e aprofundar os dados recolhidos através dos inquéritos por questionário, compreendeu a realização de entrevistas a 10 especialistas em Educação Especial e/ou em Supervisão. Os dados apontam para um enquadramento organizacional /supervisivo em Educação Especial dissemelhante, podendo, todavia, identificar-se em comum, uma satisfatória ação liderante do Coordenador da Educação Especial, baseada em atividades de diálogo e reflexão, e respeitando princípios de colaboração e solidariedade. Há, no entanto, indicadores de que a prática deste coordenador se concentra bastante na gestão burocrática e administrativa do departamento/equipa, podendo isto explicar-se pelo facto de o Coordenador da Educação Especial servir mais de intermediário do que de interveniente entre órgãos de direção e gestão, nomeadamente, entre o diretor e o conselho pedagógico, e os docentes/profissionais do departamento/equipa. Os dados evidenciam também, a falta de formação dos coordenadores da Educação Especial em supervisão e salientam a importância do fator tempo para o eficaz exercício desse cargo, de modo a promover interações ricas e estimulantes, centradas nas reflexões sobre as práticas inclusivas. Podendo este coordenador contribuir de forma significativa para a dinamização e estímulo dos profissionais do agrupamento/escola, apoiando-os nos seus esforços e iniciativas para uma organização mais inclusiva, identificam-se alguns aspetos considerados determinantes no seu perfil de competências profissionais: experiência, conhecimentos, capacidades, valores e particularidades da personalidade.

RESUMO - As organizações de saúde, para além de muito complexas, sofrem a influência de importantes mudaas em curso nos sistemas de saúde, em que se integram, e que constituem novos desafios, com reflexos na sua gestão. Por isso se espera, cada vez mais, dos seus gestores uma atitude proactiva e inovadora, o que exige que o processo educativo conducente à formação dos gestores nesta área valorize, para além de conhecimentos técnicos aprofundados, outras dimensões de um futuro exercício: desde a capacidade de lideraa em organizações em mudaa, em cenários instáveis, à disponibilidade para suscitar a colaboração dos profissionais prestadores, passando pela faculdade de criação de coligações que facilitem processos de integração multidisciplinar e plurinstitucional, pela sensibilidade à relação qualidade/custo em ambientes de constrangimento financeiro e pela promoção da inovação. O presente artigo analisa duas questões subjacentes a um bom exercício e que atravessam a concepção de qualquer processo formativo em gestão: • A competência, que deverá ser o objectivo maior da formação em gestão; • A integração da aprendizagem enquanto elemento condicionante da angariação das aptidões necessárias.

Dès sa création en 1966, l’ERAP s’est fixé pour but d’accroître la production du pétrole « franc », en diversifiant ses sources d’approvisionnement. Un tel objectif prend une tournure cruciale dès lors que les rapports tendus entre le groupe fraais et les autorités algériennes semblent menacer ses acquis dans le Sahara. Toutefois, se tailler une place sur le marché mondial semble à cette époque une tâche ardue, voire improbable, puisque les espaces les plus pétrolifères sont déjà occupés par les grandes sociétés, dites Majors. Néanmoins, la société d’État fraaise réussit à s’implanter dans plusieurs pays producteurs, dont l’Irak en 1968, jusqu’alors considéré comme la chasse gardée de la Compagnie fraaise des pétroles (CFP). Aussi, l’expérience irakienne, suite à l’insuccès en Algérie, incite Elf ERAP à se concentrer dans les pays pétroliers de l’Afrique subsaharienne et en Mer du Nord. Le 3 février 1968, Elf ERAP signe un accord avec la compagnie d’État pétrolière, INOC, pour se charger de la prospection et de l’exploitation d’une partie du territoire confisqué par l’État irakien à la puissante Iraq Petroleum Company (IPC). En contrepartie de ses apports financiers et techniques, Elf ERAP sera rémunérée par un approvisionnement garanti en pétrole irakien : il s’agit d’un nouveau genre de partenariat, dit « contrat d’agence ». Ce dernier succède au système classique des concessions et vaut à la société d’État un franc succès dans son projet de pénétration au Moyen Orient. Très vite, les prospections donnent lieu à la découverte de gisements. La production démarre en 1976 et s’élève à 5 millions de tonnes en 1977. Dès lors, Elf ERAP, devenue la SNEA, peut envisager avec optimisme son avenir énergétique, puisque sa sécurité d’approvisionnement est, en partie, assurée par le marché irakien. Mais, contre toute attente, le groupe d’État fraais se retire de l’affaire en mai 1977, laissant place à l’INOC, qui prend en charge le projet deux ans avant la date prévue par le contrat initial de 1968. Ce sujet de recherche consiste à éclaircir le rôle d’opérateur joué par l’ERAP en Irak, entre 1968 et 1977. Pour tenter d’expliquer le départ prématuré d’Elf Irak, il nous faut identifier les facteurs endogènes et exogènes qui ont pu motiver une telle décision. Autrement dit, la société d’État aurait-elle subi les revers de ses propres choix énergétiques ou un tel dénouement serait-il imputable à la politique pétrolière irakienne? Quelles sont les implications de la conjoncture pétrolière internationale dans le cas d’un tel retrait? Aidée des archives historiques d’Elf et de TOTAL, nous sommes arrivée à la conclusion que la compression du marché pétrolier, entre distributeurs et producteurs, au cours des années 1970, a considérablement nui à la rentabilité des contrats intermédiaires du type agence.

This thesis entitled' On Queues with Interruptions and Repeat or Resumption of Service' introduces several new concepts into queues with service interruption. It is divided into Seven chapters including an introductory chapter. The following are keywords that we use in this thesis: Phase type (PH) distribution, Markovian Arrival Process (MAP), Geometric Distribution, Service Interruption, First in First out (FIFO), threshold random variable and Super threshold random variable. In the second chapter we introduce a new concept called the 'threshold random variable' which competes with interruption time to decide whether to repeat or resume the interrupted service after removal of interruptions. This notion generalizes the work reported so far in queues with service interruptions. In chapter 3 we introduce the concept of what is called 'Super threshold clock' (a random variable) which keeps track of the total interruption time of a customer during his service except when it is realized before completion of interruption in some cases to be discussed in this thesis and in other cases it exactly measures the duration of all interruptions put together. The Super threshold clock is OIl whenever the service is interrupted and is deactivated when service is rendered. Throughout this thesis the first in first out service discipline is followed except for priority queues.

Die Bedeutung des Dienstgüte-Managements (SLM) im Bereich von Unternehmensanwendungen steigt mit der zunehmenden Kritikalität von IT-gestützten Prozessen für den Erfolg einzelner Unternehmen. Traditionell werden zur Implementierung eines wirksamen SLMs Monitoringprozesse in hierarchischen Managementumgebungen etabliert, die einen Administrator bei der notwendigen Rekonfiguration von Systemen unterstützen. Auf aktuelle, hochdynamische Softwarearchitekturen sind diese hierarchischen Ansätze jedoch nur sehr eingeschränkt anwendbar. Ein Beispiel dafür sind dienstorientierte Architekturen (SOA), bei denen die Geschäftsfunktionalität durch das Zusammenspiel einzelner, voneinander unabhängiger Dienste auf Basis deskriptiver Workflow-Beschreibungen modelliert wird. Dadurch ergibt sich eine hohe Laufzeitdynamik der gesamten Architektur. Für das SLM ist insbesondere die dezentrale Struktur einer SOA mit unterschiedlichen administrativen Zuständigkeiten für einzelne Teilsysteme problematisch, da regelnde Eingriffe zum einen durch die Kapselung der Implementierung einzelner Dienste und zum anderen durch das Fehlen einer zentralen Kontrollinstanz nur sehr eingeschränkt möglich sind. Die vorliegende Arbeit definiert die Architektur eines SLM-Systems für SOA-Umgebungen, in dem autonome Management-Komponenten kooperieren, um übergeordnete Dienstgüteziele zu erfüllen: Mithilfe von Selbst-Management-Technologien wird zunächst eine Automatisierung des Dienstgüte-Managements auf Ebene einzelner Dienste erreicht. Die autonomen Management-Komponenten dieser Dienste können dann mithilfe von Selbstorganisationsmechanismen übergreifende Ziele zur Optimierung von Dienstgüteverhalten und Ressourcennutzung verfolgen. Für das SLM auf Ebene von SOA Workflows müssen temporär dienstübergreifende Kooperationen zur Erfüllung von Dienstgüteanforderungen etabliert werden, die sich damit auch über mehrere administrative Domänen erstrecken können. Eine solche zeitlich begrenzte Kooperation autonomer Teilsysteme kann sinnvoll nur dezentral erfolgen, da die jeweiligen Kooperationspartner im Vorfeld nicht bekannt sind und – je nach Lebensdauer einzelner Workflows – zur Laufzeit beteiligte Komponenten ausgetauscht werden können. In der Arbeit wird ein Verfahren zur Koordination autonomer Management-Komponenten mit dem Ziel der Optimierung von Antwortzeiten auf Workflow-Ebene entwickelt: Management-Komponenten können durch Übertragung von Antwortzeitanteilen untereinander ihre individuellen Ziele straffen oder lockern, ohne dass das Gesamtantwortzeitziel dadurch verändert wird. Die Übertragung von Antwortzeitanteilen wird mithilfe eines Auktionsverfahrens realisiert. Technische Grundlage der Kooperation bildet ein Gruppenkommunikationsmechanismus. Weiterhin werden in Bezug auf die Nutzung geteilter, virtualisierter Ressourcen konkurrierende Dienste entsprechend geschäftlicher Ziele priorisiert. Im Rahmen der praktischen Umsetzung wird die Realisierung zentraler Architekturelemente und der entwickelten Verfahren zur Selbstorganisation beispielhaft für das SLM konkreter Komponenten vorgestellt. Zur Untersuchung der Management-Kooperation in größeren Szenarien wird ein hybrider Simulationsansatz verwendet. Im Rahmen der Evaluation werden Untersuchungen zur Skalierbarkeit des Ansatzes durchgeführt. Schwerpunkt ist hierbei die Betrachtung eines Systems aus kooperierenden Management-Komponenten, insbesondere im Hinblick auf den Kommunikationsaufwand. Die Evaluation zeigt, dass ein dienstübergreifendes, autonomes Performance-Management in SOA-Umgebungen möglich ist. Die Ergebnisse legen nahe, dass der entwickelte Ansatz auch in großen Umgebungen erfolgreich angewendet werden kann.

Food safety management systems (FSMSs) and the scrutinisation of the food safety practices that are intended for adoption on the firm level both offer strategic value to the dried fig sector. This study aims to prove the hypothesis that export orientation is a major motivating force for the adoption of food safety systems in the Turkish dried fig firms. Data were obtained from 91 dried fig firms located in Aydin, Turkey. Interviews were carried out with firms’ managers/owners using a face-to-face questionnaire designed from May to August of 2010. While 36.3 percent of the interviewed firms had adopted one or more systems, the rest had no certification. A binomial logistic econometric model was employed. The parameters that influenced this decision included contractual agreements with other firms, implementation of good practices by the dried fig farmers, export orientation and cost-benefit ratio. Interestingly, the rest of the indicators employed had no statistically significant effect on adoption behaviour. This paper focusses on the export orientation parameter directly in order to test the validity of the main research hypothesis. The estimated marginal effect suggests that when dried fig firms are export-oriented, the probability that these firms will adopt food safety systems goes up by 39.5 percent. This rate was the first range observed among all the marginal probability values obtained and thus verified the hypothesis that export orientation is a major motivator for the adoption of food safety systems in the Turkish dried fig firms.
