    Full Text Available CONTEXTO: Tem sido sugerido que durante as crises convulsivas induzidas pela pilocarpina pode ser observado aumento no estresse oxidativo cerebral. Estudos sugerem que compostos com atividade antioxidante podem fornecer certo grau de proteção contra a neurotoxicidade induzida pelas crises convulsivas. OBJETIVOS: O presente estudo investigou as ações farmacológicas da vigabatrina nas alterações comportamentais e na atividade enzimática da superóxido dismutase (SOD no corpo estriado de ratos adultos. MÉTODOS: Ratos Wistar adultos (2 meses de idade foram usados nos experimentos e divididos em quatro grupos. O primeiro foi tratado com solução salina 0,9% (grupo controle. O segundo grupo foi tratado com pilocarpina (400 mg/kg, i.p., grupo P400. O terceiro grupo foi tratado com vigabatrina (500 mg/kg, i.p., grupo VGB e o quarto grupo foi tratado com vigabatrina (500 mg/kg, i.p. e 30 minutos depois com pilocarpina (400 mg/kg, i.p., grupo VGB + P400. Os animais que apresentaram crises convulsivas, estado de mal epiléptico e não morreram durante o período de 24 horas de observação foram sacrificados para dissecação do corpo estriado para realização da determinação da atividade da SOD. RESULTADOS: Os estudos comportamentais revelaram que, após administração de pilocarpina, todos os animais apresentaram sinais colinérgicos periféricos, movimentos estereotipados e tremores. No mesmo grupo, foram observados, em 75% dos animais, crises convulsivas e o estado de mal epiléptico. Por sua vez, o pré-tratamento com vigabatrina produziu redução significativa de 50% nas crises convulsivas. Com relação aos estudos neuroquímicos, não foram observadas alterações na atividade da SOD no corpo estriado do grupo P400, em comparação aos valores do grupo controle. No entanto, no grupo VGB + P400 foi visto aumento significativo na atividade da SOD de 34% e 35%, quando comparado aos grupos controle e P400, respectivamente. CONCLUS

    Full Text Available O insulinoma é doença rara que cursa com sintomas episódicos neuroglicopênicos e/ou adrenérgicos. Descrevemos o caso de uma paciente de 36 anos, que estava sendo tratada por crises convulsivas parciais complexas há 4 anos sem melhora do quadro. Apresentava história de vários episódios de crise convulsiva associada a hipoglicemia marcante. Tomografia de crânio e eletrencefalograma eram normais. No teste de jejum de 72 horas evidenciaram-se sintomas hipoglicêmicos, que eram revertidos com reposição de glicose, associados com insulina e peptídeo C elevados. A localização do insulinoma foi possível apenas após laparotomia exploradora; os métodos de imagem utilizados não revelaram o tumor. O exame histopatológico confirmou neoplasia endócrina diferenciada. Concluímos que a dosagem da glicemia deve fazer parte da investigação de transtornos convulsivos ou do comportamento, pois o insulinoma pode inicialmente apresentar-se desta forma.Insulinoma is a rare disease presenting with episodic neuroglycopenic and/or adrenergic symptoms. We describe the case of a 36 year-old female that had been in treatment for complex partial seizures during 4 years without improvement. She presented many crises with marking hypoglycemia. Cranium tomography and electroencephalogram were normal. A 72-hour fast test showed hypoglycemic symptoms with raised insulin and C-peptide. The insulinoma localization was possible during exploratory laparatomy; image metods did not reveal the tumor. Histological findings confirmed an insulinoma. We conclude that blood glucose level should be requested during the investigation of convulsive and behavioral disorders since an insulinoma can present like them.

    Full Text Available Objetivo: estudar a grande variação dos prognósticos relatados após a primeira crise convulsiva não provocada e dos fatores de risco que são associados com recorrência, estabelecendo uma conduta uniforme. Fontes dos dados: revisão sistemática das citações do banco de dados da Bireme. Síntese dos dados: a taxa de recorrência difere nos estudos de primeira crise em conseqüência dos diferentes critérios de inclusão. O eletrencefalograma (EEG é particularmente útil na determinação da natureza epiléptica de um evento nos pacientes mais jovens e naqueles com crises de origem desconhecida. Um EEG anormal, particularmente com descargas de ponta-onda generalizadas, tem sido relatado como um preditor de recorrência consistente. Embora não seja um substituto para o exame clínico, o EEG é parte integral do processo diagnóstico após a primeira crise afebril, e deve ser solicitado. A decisão quanto tratar ou não os pacientes que apresentaram uma crise única depende fortemente do conhecimento do médico da potencial morbidade de uma outra crise versus a potencial morbidade da terapia com drogas antiepilépticas (DAEs. Conclusões: em crianças, efeitos colaterais das DAEs são comuns, e o risco de injúria após uma crise geralmente é mínimo, já que elas não se expõem a situações de extremo risco, como a condução de automóveis ou a operação de máquinas, além do fato de geralmente estarem em ambiente supervisionado. Em adultos, esta unanimidade é pequena.Objective: to observe the wide variety of reported prognosis after a first unprovoked convulsion and of risk factors that are associated with recurrence, and a uniform conduct. Sources: systematic review of Bireme. Summary of the findings: recurrence rates differ from a first seizure study because of different inclusion criteria. The EEG is particularly helpful to support the epileptic nature of the event in younger patients and in those with seizures of unknown

    Full Text Available Estudo do comportamento das concentrações de cloro, sódio, potássio e fósforo inorgânico no LCR de 33 pacientes na vigência de crises convulsivas e de 17 pacientes epilépticos na interfase de crises convulsivas. Os resultados obtidos foram estudados em comparação aos valôres normais anteriormente relatados. Não foram encontradas modificações quanto às taxas de íons estudados no LCR dos pacientes epilépticos examinados no período intercrítico. Foram verificadas alterações das taxas de íons estudados no LCR entre os pacientes estudados na vigência de crise convulsiva. As alterações encontradas se caracterizavam por aumento das taxas de potássio e de fósforo inorgânico. Os aumentos encontrados foram estatisticamente significantes. A taxa de sódio no LCR dos pacientes cuja crise convulsiva não se associava a outras manifestações de doença se apresentava, em média, aumentada. Diminuição das taxas médias de sódio e de cloro foi constatada entre os pacientes cuja crise convulsiva ocorreu durante reidratação. Os resultados foram discutidos em relação a dados da literatura quanto às modificações do metabolismo iônico envolvidas nos fenômenos de despo- larização de membrana, que ocorrem na crise convulsiva. Os aumentos verificados para as concentrações de potássio e de fósforo inorgânico no LCR durante a crise convulsiva confirmam os dados quanto à passagem dêsses ions do espaço intracelular para o extracelular nessas condições, já registrados através de estudos feitos no sangue e em amostras de cérebro de epilépticos.

    Full Text Available INTRODUCTION: Dom Pedro II, the Prince Heir and Emperor under regency, in a delicate period of the construction of the Brazilian nation, had convulsive seizures. OBJECTIVE: To investigate the convulsive seizures and related syndromes of Dom Pedro II and his family, besides the physicians in charge of the health care. METHOD: Narrative review based on primary and secondary sources. CONCLUSION: The scattered and self-limited convulsive seizures associated with physical and mental integrity favored a benign prognosis. Dom Pedro and his family presented rich history of epileptic seizures and febrile convulsion. This variety resembles the diagnosis of generalized epilepsy with febrile seizures plus that seems to be a combination of several syndromes with shared genetic susceptibility.INTRODUÇÃO: Dom Pedro, o príncipe herdeiro e imperador sob regência, em período delicado da formação da nação brasileira, apresentou crises convulsivas que geraram preocupação para o país. OBJETIVO: Investigar a história da epilepsia de Dom Pedro II e da sua família e procurar identificar quais tipos de crises epilépticas estavam presentes, além dos médicos envolvidos com os cuidados de saúde. MÉTODO: Revisão narrativa baseada em fontes primárias e secundárias. CONCLUSÃO: As crises convulsivas esparsas e auto-limitadas associadas a higidez física e mental de Dom Pedro II sugerem um prognóstico benigno. A história de epilepsia idiopática e convulsões febris no imperador e em outros membros da sua família aponta para o diagnóstico mais provável de Epilepsia Generalizada com Convulsões Febris Plus que é determinada por uma combinação de alguns tipos de manifestações epilépticas com suscetibilidade genética compartilhada.

    1991-12-01

    Full Text Available Levando em conta o número restrito de casos em âmbito internacional e a ausência de publicações na literatura nacional, os autores apresentam três casos de crises motoras focais induzidas por movimentos em pacientes diabéticos com mais de 50 anos de idade. As crises eram numerosas, sendo também desencadeadas ao serem assumidas determinadas posturas. Em dois casos havia hiperglicemia não cetótica. Todos os pacientes apresentavam hemiparesia e, em dois, tal déficit desapareceu após o cotnrole das crises. No outro paciente a hemiparesia era decorrente de acidente vascular cerebral isquêmico instalado 6 meses antes. Síndrome parietal transitória foi observada nos três pacientes. O EEG crítico mostrou, em dois pacientes, descargas na região parieto-occipital e, em um, na região temporal média contralateral. As crises foram resistentes aos anticonvulsivantes, só havendo controle com o tratamento dos distúrbios metabólicos. São discutidos aspectos clínico-eletren-cefalográficos e etiopatogênicos. A pesquisa do caráter reflexo das crises e a dosagem da glicemia devem ser feitas em todos os pacientes idosos com crises motoras focais, face às implicações de ordem terapêutica e prognóstica.

    Full Text Available This study was designed with the objective of evaluating the chance of recurrence in our area and to answer questions regarding prognostic factors capable of helping in the management of the first seizure in childhood. One hundred and thirty six children from 1 month to 12 years of age seen at the Pediatric Emergency Division of Hospital de Clínicas de Porto Alegre because of a first seizure with or without triggering factors were included in the study. The follow-up included 121 children. We concluded that family history of seizures, presence of triggering factors at first event, seizure type, seizure duration and paroxysmal electroencephalographic abnormalities were predictive factors for seizure recurrence. The recurrence in this sample was 36.36% during the study. Cumulative recurrence risks were 14.88%, 23.14%, 28.93%, 33.06% and 35.54% to 3, 6, 9, 12 and 15 months, respectively.Este estudo foi elaborado com a finalidade de avaliar a possibilidade de recorrência e de responder a questões referentes a fatores prognósticos capazes de auxiliar no manejo da primeira crise convulsiva na infância. Foram incluídas 136 crianças com idades entre 1 mês e 12 anos atendidas no Setor de Emergência Pediátrica do Hospital de Clínicas de Porto Alegre por ocasião da primeira crise convulsiva, com ou sem fator desencadeante. Foram seguidas 121 crianças por 24 meses, concluindo-se que história familiar de crise convulsiva, existência de fatores desencadeantes na primeira convulsão, tipo de crise, duração da crise e alterações paroxísticas no primeiro eletrencefalograma foram fatores preditivos para a recorrência de crise convulsiva. A recorrência foi de 36,36% no tempo em que durou o estudo. Os riscos acumulados para recorrência nesta amostra foram 14,88%, 23,14%, 28,93%, 33,06% e 35,54% para 3, 6, 9, 12 e 15 meses, respectivamente.

    Full Text Available Objetivos: determinar a freqüência de recorrência das crises convulsivas após tratamento com sulfato de magnésio, avaliando o tratamento adotado e o prognóstico materno. Casuística e Métodos: analisaram-se todos os casos de eclâmpsia atendidos no IMIP entre janeiro de 1995 e junho de 1998. Sulfato de magnésio e oxigenoterapia foram administrados para todas as pacientes, interrompendo-se a gravidez após estabilização do quadro clínico. Determinou-se a freqüência de complicações maternas de acordo com a presença ou não de recorrência da crise convulsiva, utilizando-se o teste chi² de associação, a um nível de significância de 5%. Resultados: doze pacientes apresentaram recorrência da eclâmpsia após sulfato de magnésio (10%, repetindo-se então metade da dose de ataque. Em 4 destas verificou-se nova recorrência, administrando-se então diazepam endovenoso. Depois do diazepam, uma paciente ainda teve crises repetidas, sendo então realizada infusão de fenitoína e, posteriormente, indução do coma barbitúrico (tionembutal. Essa paciente foi submetida a tomografia computadorizada, constatando-se hemorragia intracraniana. As complicações maternas foram significativamente mais freqüentes no grupo com recorrência: coma (16,7% versus 0,9%, acidose (50% versus 2,9%, edema agudo de pulmão (16,7% versus 2,9%, hemorragia cerebral (16,7% versus 0% e insuficiência renal aguda (16,7% versus 1,9%. Ocorreram 3 casos de morte materna no grupo com recorrência (25% e 2 no grupo sem recorrência (1,9%. Conclusões: a recorrência da crise convulsiva é pouco freqüente após uso do sulfato de magnésio (10%, porém associa-se a aumento da morbimortalidade materna, requerendo acompanhamento em UTI e realização de tomografia para exclusão de hemorragia cerebral.Purpose: to determine the frequency of recurrence of seizures after anticonvulsant therapy with magnesium sulfate and to evaluate treatment and maternal prognosis

Na primeira, a crise residiria em estar cedendo lugar às disciplinas em que se desmembrou (biofísica, bioquímica, farmacologia e, mesmo, imunologia e cada vez menos tendo a possibilidade de fazer pesquisa de ponta. Na segunda, o sentido da pesquisa teria divergido do concebido pelos seus instituidores, que deveria ser o de subsidiar as análises filogenéticas hauridas da anatomia, embriologia e paleontologia. Enfatiza que as referidas disciplinas continuam fisiológicas, a visão holística propiciada pela fisiologia clássica persiste importante e seus problemas de natureza sistêmica estão longe da elucidação satisfatória. Também não procederia a crítica feita à fisiologia comparativa de fracasso nas tentativas de compatibilizar as funções com a filogenia, pois, em casos significativos houve sucesso. Ademais, a fisiologia comparativa, na evolução de seus objetivos, ganhou novas conotações, mormente a ecológica, em que convergências antes que alinhamentos filogenéticos são buscados. Além disso, essa fisiologia tem oferecido à pesquisa básica animais, modelos experimentais mais simples, extremamente adequados ao estudo de funções complexas. Assim, não haveria crises num sentido de perda de objetivos ou mudança de paradigma nos dois casos. Novos rumos?

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Opioides são medicamentos frequentemente usados para o controle da dor que, contudo, podem causar hiperalgesia. A circunstância pela qual esse fenômeno pode ocorrer não está inteiramente esclarecida. O objetivo desta revisão foi descrever os mecanismos, os fatores implicados e a modulação por medicamentos. CONTEÚDO: Foram descritos os fatores implicados no desenvolvimento da hiperalgesia induzida por opioides (HIO, como duração de uso, dose e tipo de opioide. Os mecanismos incluem o sistema glutamatérgico e receptores N-metil-D-aspartato (NMDA, ativação de ciclo-oxigenase (COX espinal, aminoácidos excitatórios, dinorfina, citocinas e quimocinas; prostaglandinas e facilitação descendente. A modulação de hiperalgesia pode ser feita com antagonistas de receptores NMDA, agonistas adrenérgicos-alfa2 e inibidores de COX. CONCLUSÕES: O assunto é bastante complexo, envolvendo uma série de mecanismos fisiopatológicos que podem contribuir para a HIO e o desconforto do paciente, trazendo consequências que podem ser danosas.

    Full Text Available CONTEXTO: Crises epilépticas induzidas por pilocarpina podem produzir alterações histopatológicas em muitas regiões cerebrais como consequência da produção excessiva de radicais livres. OBJETIVO: O objetivo do presente estudo foi avaliar o efeito antioxidante da buspirona no modelo de epilepsia induzida por pilocarpina. MATERIAL E MÉTODOS: Quarenta e oito animais foram divididos em quatro grupos. O primeiro grupo foi tratado com solução salina 0,9% (Controle. O segundo grupo foi tratado com pilocarpina 400 mg/kg (P400. Por sua vez, o terceiro grupo foi tratado com buspirona 5 mg/kg (BUSP durante 14 dias consecutivos. Já os animais do quarto grupo foram tratados com buspirona durante 14 dias consecutivos, e, 30 minutos após a última administração dela, os camundongos receberam P400 (BUSP + P400. RESULTADOS: Durante o período do tratamento não se observaram sinais de toxicidade e nenhuma morte entre os animais tratados com buspirona. Em nosso estudo o grupo tratado com P400 demonstrou um aumento significativo da produção de nitrito e nos níveis de peroxidação lipídica após as crises epilépticas. Por outro lado, no hipocampo dos animais que receberam o pré-tratamento com buspirona e após 30 minutos receberam P400, foi observada redução significativa nos níveis de peroxidação lipídica (65% e nitrito (85%, bem como aumento na atividade da enzima superóxido dismutase. CONCLUSÃO: O pré-tratamento com BUSP aumentou a latência para primeira crise epiléptica e diminuiu a taxa de mortalidade e o número de animais que apresentaram crise epiléptica e que progridem para o estado de mal epiléptico. Além disso, apresentou efeitos anticonvulsivantes associados com a redução do estresse oxidativo hipocampal no modelo de epilepsia induzida por pilocarpina.

    Full Text Available A terapia convulsiva (TC constitui uma das principais contribuições européias ao tratamento psiquiátrico moderno e à psiquiatria biológica. A TC foi introduzida na psiquiatria em 1934 por László Meduna, neuropsiquiatra húngaro. As publicações subseqüentes sobre o primeiro paciente tratado com TC, Zoltán L (ZL, baseiam-se nos artigos e na autobiografia de Meduna. De acordo com essas referências, após quatro anos de estupor catatônico, ZL recebeu TC induzida por cânfora que resultou em plena remissão dos sintomas esquizofrênicos, culminando com alta da instituição. Este artigo reconstrói a história do caso de ZL a partir da recente recuperação de anotações - algumas escritas pelo próprio Meduna - dos Arquivos do Instituto Nacional de Psiquiatria e Neurologia (Hungria. Essas anotações mostram que ZL recebeu repetidas sessões de TC entre 1934 e 1937, primeiramente induzidas por cânfora e depois por cardiazol. A primeira série de TC resultou na suspensão do estupor catatônico e na remissão parcial da psicose. Entretanto, a remissão foi breve e, a despeito de repetidas sessões de TC, ZL nunca esteve inteiramente livre de sintomas, nunca teve alta hospitalar e veio a falecer no Instituto em 1945. Na discussão do caso de ZL, tentamos explicar as possíveis razões das discrepâncias entre o relato de Meduna e as notas originais do prontuário médico.Convulsive therapy (COT is a major European contribution to the psychiatric armamentarium and biological psychiatry. COT was introduced in psychiatry by László Meduna, a Hungarian neuropsychiatrist. All subsequent publications about the first patient treated with COT, Zoltán L (ZL, were based on Meduna's papers and autobiography. After 4 years of catatonic stupor, ZL received camphor-induced COT which resulted in full remission and discharge from the institution.

    Full Text Available Neurogenesis in the dentate gyrus (DG has attracted attention since abnormal supragranular mossy fiber sprouting occurs in the same region, in temporal lobe epilepsy. Thus, we submitted developing rats to pilocarpine-induced status epilepticus (SE to study the relationship between neurogenesis and mossy fiber sprouting. Groups were submitted to SE at: I-P9, II-P7, P8 and P9, III-P17 e IV-P21. Neurogenesis was quantified using BrdU protocol and confirmed through double staining, using neuronal pentraxin. Other animals were monitored by video system until P120 and their brain was studied (Timm and Nissl staining. The neurogenesis at P17 (p=0.007 and P21 (p=0.006 were increased. However, only P21 group showed recurrent seizures and the mossy fiber sprouting in the same region, during adult life, while P17 did not. Thus, our results suggest that neurogenesis is not related to mossy fiber sprouting neither to recurrent spontaneous seizures in pilocarpine model.A neurogênese no giro dentado tem atraído atenção já que ela ocorre na mesma região do hipocampo que o brotamento das fibras musgosas, na epilepsia do lobo temporal. Assim, submetemos ratos em desenvolvimento ao status epilepticus induzido (SE por pilocarpine. Grupos foram submetidos em I-P9, II-P7, P8, P9; III-P17 e IV-P21. A neurogênese foi observada usando o protocolo do BrdU e confirmada por dupla marcação com pentraxina neuronal. Outros animais foram monitorados até P120 e seus cérebros analisados (Nissl e Timm. A neurogênese nos grupos P17 (p=0,007 e P21 (p=0,006 aumentaram. Entretanto, o P21 apresentou crises espontâneas e brotamento de fibras musgosas, na mesma região onde ocorreu a neurogênese, enquanto o grupo P17 apresentou somente aumento na neurogênese. Assim, nossos resultados sugerem que o fenômeno da neurogênese não está relacionado com o brotamento de fibras musgosas nem com o aparecimento de crises espontâneas e recorrentes no modelo da pilocarpina.

Diversos estudios han mostrado beneficios en la salud con la implementación de los O-3 como agentes terapéuticos en alteraciones cardiovasculares, renales, dérmicas, metabólicas, neurodegenerativas e inmunológicas. Evidencias experimentales sugieren un beneficio potencial del aceite de pescado (APE como neuroprotector debido al alto contenido de DHA y EPA. Sin embargo, es poco lo que se conoce en cuanto a los efectos que pudieran tener sobre alteraciones nerviosas, como las crisis convulsivas. En este contexto, se ha reportado que el tipo más común de trastorno epiléptico observado en los niños son las crisis convulsivas provocadas por fiebre (CF. La incidencia es de 3-5%, con ocurrencia entre los 5 meses y 5 años de edad, y se ha propuesto que esta alteración en la vida temprana pudiera tener efectos a largo plazo, manifestándose como un síndrome de epilepsia en la vida adulta. El objetivo del presente estudio fue evaluar el efecto del APE sobre las convulsiones inducidas por hipertermia experimental en un grupo de ratas Wistar macho de 5 días de edad (grupo SAPE cuyas madres consumieron una dieta base más un suplemento de APE (suministrado desde su infancia hasta la etapa de crianza. Este grupo se comparó con otro grupo de ratas de la misma edad y cepa (grupo SAPA cuyas madres consumieron una dieta base más un suplemento de aceite de palma (suministrado desde su infancia hasta la etapa de crianza, y con un tercer grupo de ratas (grupo CTRL cuyas madres consumieron la dieta base más agua bidestilada como suplemento.

    Full Text Available Hemodialysis-associated seizure is a complication of hemodialysis. This report describes the occurrence of seizures in patients with end stage renal disease on dialysis therapy at the Nephrology Institute of Mogi das Cruzes, São Paulo State, Brazil. A retrospective medical history of 189 patients was reviewed to investigate the occurrence of convulsive seizures during dialytic program. Seven patients with history of seizures were selected but five of them were included in our study. Three patients presented generalized tonic-clonic seizures, one had partial seizure with secondary generalization, and one presented unclassified seizure. Three patients presented seizure just during the dialysis (unique seizure and one of them presented convulsive status epilepticus. The two other patients had already presented seizures prior the beginning of dialysis. We conclude that seizures in renal failure could be considered as occasional events that do not usually become chronic.Convulsões durante o tratamento dialítico podem constituir uma complicação da hemodiálise. Esse artigo descreve a ocorrência de crises em pacientes em estágio final de insuficiência renal crônica sob tratamento dialítico no Instituto de Nefrologia de Mogi das Cruzes, São Paulo, Brasil. Foram revistos os prontuários de 189 pacientes, com o objetivo de investigar a ocorrência de crises convulsivas durante o tratamento dialítico. Dos sete pacientes selecionados com história de crises, cinco concordaram em participar de nosso estudo. Três pacientes apresentaram crises generalizadas tônico-clônicas, um apresentou crise parcial com generalização subseqüente e um apresentou crise inclassificada. Três pacientes apresentaram crises apenas durante o processo dialítico (crise única sendo que um deles apresentou status epilepticus convulsivo.

Foram selecionadas 112 crianças com CE recorrentes e espontâneas. O estudo foi dividido em duas partes. Na Parte I avaliamos a idade na primeira crise, modo de início, semiologia pré-ictal, ictal e pós-ictal. Na Parte II a classificação das CE: a segundo padrão motor convulsivo, em convulsivas / não convulsivas; e b segundo o esquema da Liga Internacional Contra Epilepsia ( ILAE, 1981. Os resultados significantes foram a descrição de auras epilépticas em 42,9%, sinais localizatórios em 36,6% e a descrição semiológica motora em 95,5%, neurovegetativa em 56,3%, psíquica em 32,1% e sensitivo-sensorial em 4,5%. Foram classificadas pela semiologia motora as CE convulsiva em 83% e não convulsiva em 17% . No esquema da ILAE obteve-se na amostra geral 12,5% de CE não classificadas, pela dicotomia foram classificadas as CE parciais em 59,9% e as generalizadas em 27,2 % . Um alto índice de aproveitamento das informações foi obtido com 87,5% de CE classificadas.Este resultado nos permite concluir ser possível classificar clinicamente e com segurança as crises epilépticas com base na descrição dos pais e ou responsáveis, utilizando-se protocolo padronizado.

    Full Text Available Timely, provocative, and theoretically sophisticated, the essays comprising In the Face of Crises: Anglophone Literature in the Postmodern World situate their work amid several critical global concerns: the devastation wreaked by global capitalism following the worldwide financial crash, the financial sector’s totalizing grip upon the world economy, the challenge to traditional definitions of “human nature” and identity posed by technologies of the body and of warfare, the quest of indigenous communities for healing from the continuing traumatic effects of colonization, and the increasing corporatization of the academy as an apparatus of the neo-liberal state – to specify only a few. Edited by Professors Ljubica Matek and Jasna Poljak Rehlicki, these essays deploy a broad range of contemporary theories, representing recent developments in cultural studies, the new economic criticism, postcolonial film studies, feminism and gender studies, and the new historicism. The eleven essays selected by Matek and Rehlicki offer convincing support for their claim that humanistic research delving into Anglophone literature, far from being a “non-profitable” pursuit in an increasingly technologized society, affords clarifying insights into contemporary “economic, cultural, and social processes in the globalizing and globalized culture of the West” (ix.

    Full Text Available Financial crises mainly manifest themselves at the level of financial institutions. Although financial crises can also be generated within non-financial institutions, the role of banking institutions in the occurrence, transmitting and solving of financial crises is a deciding one. Banks play a deciding role in the development of financial crises as financial intermediaries who contribute to the efficient transfer of funds from the abundant agent towards the deficit agents. Banks can facilitate the financial crises through the activities performed on the financial markets that can influence the interest rates, the uncertainty on the market and the price of assets, but moreover bank crises can occur that transform financial crises. This paper aims to analyze the role of banks in the emergence, the propagation, the prevention or solving financial crises.

    Full Text Available O objetivo deste relato é fazer uma revisão a fim de obter informações atualizadas sobre trombocitopenia induzida por heparina, suas manifestações clínicas, seu diagnóstico e seu manejo terapêutico. Após, concluímos que a trombocitopenia induzida por heparina é uma complicação comum em pacientes submetidos a tratamento com heparina, indiferentemente da doença de base. Complicações trombóticas potencialmente fatais têm sido descritas. Por essa razão, se houver suspeita de trombocitopenia induzida por heparina, uma abordagem adequada incluindo suspensão precoce da heparina é mandatória. Produtos que substituem a heparina incluem hirudina e danaparóide sódico. Heparina de baixo peso molecular é contra-indicada.The aim of this paper is to review current information about the clinical manifestations, diagnosis and management of heparin-induced thrombocytopenia. This was achieved by a bibliographic review using Public Medline and consulting Hematology textbooks. From this study we concluded that heparin-induced thrombocytopenia is a common complication of patients exposed to heparin therapy regardless of underlying conditions. Potentially fatal thrombotic complications have been reported. Therefore, if heparin-induced thrombocytopenia is suspected, an adequate approach including early heparin discontinuation is mandatory. Alternative products for heparin include hirudin and danaparoid sodium. Low-molecular-weight heparin is contraindicated.

    Economic crises in the last decades have swept elderly workers more than younger workers out of employment. But now the tide is turning. In affluent societies, elderly workers will have more opportunities of being employed in meaningful and well-paid jobs than ever before. On account of demographic changes, fewer (younger) workers will be around, and most of the reasons that in the past have induced employers to lay off older rather than younger workers will disappear. Future employment strategies will have to focus more on an optimal age mix and on benefitting from the full potential of the elderly. Copyright © 2011 S. Karger AG, Basel.

    Economists have been blamed for their inability to forecast and address crises. This paper attributes this inability to intertwined factors: the lack of a coherent definition of crises, the reference class problem, the lack of imagination regarding the nature of future crises, and sample selection biases. Specifically, economists tend to adapt their views on crises to recent episodes, and omit averted and potential crises. Threshold-based definitions of crises run the risk of being ad hoc. Us...

    Full Text Available A necessidade de intubação e do uso de ventilação mecânica na prematuridade está relacionada à chamada lesão pulmonar induzida pela ventilação e à consequente displasia broncopulmonar. Busca-se a melhor compreensão dos mecanismos de lesão envolvendo resposta inflamatória mediada pelas citocinas para o desenvolvimento de novas estratégias protetoras. Pesquisou-se na base de dados PubMed, incluindo artigos relevantes, os unitermos "ventilator induced lung injury preterm", "continuous positive airway pressure", "preterm" e "bronchopulmonary dysplasia". Dados e informações significativas foram compilados em tópicos, com o objetivo de formar uma visão crítica e plena acerca da lesão induzida pela ventilação e de suas consequências ao prematuro. Foi revisado o papel das citocinas pró-inflamatórias como mediadores da lesão, especialmente interleucinas 6 e 8, e fator de necrose tumoral alfa. Foram apresentadas evidências em estudos com animais e também em humanos, mostrando que breves períodos de ventilação mecânica são suficientes para a liberação dessas interleucinas inflamatórias. Também foram revisadas outras formas de ventilação mecânica e de ventilação não invasiva, como alternativas protetoras aos modos convencionais. Concluiu-se que o uso de ventilação não invasiva, a intubação com administração precoce de surfactante e a extubação rápida para CPAP nasal, além de estratégias que regulam o volume corrente evitando o volutrauma (como a ventilação com volume garantido, são medidas protetoras da lesão pulmonar induzida pela ventilação mecânica no prematuro.

  4. Energy crises and Japanese response

    Japan, who depends on foreign sources for nearly 80% of her energy needs, experienced the most serious recession and industrial adjustment processes of the post-war period when world oil prices suddenly soared in 1973 and 1979. Yet, she has overcome the oil crises more successfully than any other industrialized nation. This paper examines her economic performance in the years following the first oil crisis and concludes that the important factors contributing to her success were not so much her energy-specific policies as her stringent monetary-fiscal policies, restrained unions' wage demands, industries' investments in energy-saving facilities and quality control techniques, and shift in production from energy-intensive to high-technology, knowledge-intensive products, along with the expansionary policies taken by the US after the first oil crisis. 6 references, 9 figures, 2 tables.

Se expone el caso de un varón de 42 años que fallece por broncoaspiración alimentaria secundaria a crisis convulsiva. El estudio neuropatológico puso de manifiesto dos lipomas situados en la rodilla del cuerpo calloso. Se destaca la necesidad de realizar tratamiento antiepiléptico en los lipomas del cuerpo calloso que se manifiestan clínicamente en forma de crisis comiciales.Lipomas of the corpus callosum make up approximately 5% of the tumours of the corpus callosum. Nowadays, they are considered congenital malformations rather than true neoplasms. They are usually asymptomatic; however they are sometimes associated with unspecific neurological symptoms such as psychomotor retardation, headache, epilepsy and cerebral palsy. A case is presented of a 42-year-old man who died due to alimentary aspiration following a seizure. Neuropathological study showed two lipomas located in the splenium of the corpus callosum. Also, we emphasise the importance of the anti-epileptic treatment in the corpus callosum lipomas which are associated with epilepsy.

    Full Text Available This paper analyzes the twin crises in Turkey experienced in 2000 and 2001. After a detailed survey of currency crisis models, together with a brief descriptive overview of the crises in Turkey, the similarities among the twin crises in Turkey and the models that have been developed to explain preceding crises in the world are investigated. It is found that the Turkish twin crises cannot be explained by using any individual generation of models, namely first generation models, second generation models or third generation models. Instead, a combination of these models is more appropriate to explain the details of the twin crises.

    Oculogyric crises are a rare movement disorder characterized by paroxysmal, conjugate, tonic, usually upwards, deviation of the eyes. Causes for oculogyric crises are limited and include complications of dopamine-receptor blocking medications and neurometabolic disorders affecting dopamine metabolism, suggesting that an underlying hypodopaminergic state is important to the pathogenesis. Mimickers of oculogyric crises exist, and we propose diagnostic criteria to distinguish true oculogyric crises. Recognition of oculogyric crises is important for the diagnosis and appropriate treatment of rare disorders, and an approach to investigations in oculogyric crises is proposed. © 2017 International Parkinson and Movement Disorder Society.

    Harris, Wesley; Le Floch, Francois

    2006-11-01

    Recent developments in sickle cell research and blood flow modeling allow for new interpretations of the sickle cell crises. With an appropriate set of theoretical and empirical equations describing the dynamics of the red cells in their environment, and the response of the capillaries to major changes in the rheology, a complete mathematical system has been derived. This system of equations is believed to be of major importance to provide new and significant insight into the causes of the disease and related crises. With simulations, it has been proven that the system transition from a periodic solution to a chaotic one, which illustrates the onset of crises from a regular blood flow synchronized with the heart beat. Moreover, the analysis of the effects of various physiological parameters exposes the potential to control chaotic solutions, which, in turn, could lead to the creation of new and more effective treatments for sickle cell anemia. .

  13. A model of international financial crises

    Science.gov (United States)

    Kaizoji, Taisei

    2001-10-01

    This paper proposes a model of international financial crises that is based on the statistical mechanics. In our model the international stock market is composed of two groups of traders mutually influencing each other with respect to their decision behavior, and financial contagion between markets occurs as a result of attempts by traders in the domestic market to imitate the behavior of traders who participate into exchange in a foreign market. This provides a channel through which a crisis in one market such as contemporaneous stock market crashes can be transmitted to other markets. We show that the model can explain the stylized facts characterizing periods of recent international financial crises.

  1. FOREIGN DIRECT INVESTMENTS DURING FINANCIAL CRISES

    Directory of Open Access Journals (Sweden)

    VINTILA DENISIA MARIANA

    2011-12-01

    Full Text Available The fundamental idea of International capital flows is that short-term flows can be easily reversed, while flows on a longer time horizon are more stable. Crises are associated with withdrawals of short-term capital flows and growth of the foreign direct investment flows. The current crisis has meant a major decline of international capital flows, also of the foreign direct investment. The analysis in this article tries to establish if and under which conditions foreign direct investments can bring greater stability during the crisis, comparing the evolution of foreign direct investments in the current crisis with their response in previous crises. We show that during previous crises foreign direct investments were stable, behaving differently from other types of capital. Yet, during the current crisis, foreign direct investments have proven to be not so stable and all the components declined, raising questions about the resumption of the positive trend. The stability of foreign direct investments in the past was given by the increase of mergers and acquisitions during the crisis, reflecting fire-sale FDI. This feature is not found in the current crisis as mergers and acquisitions were severe affected by the crises and recorded a major decline.

    Full Text Available In this paper we are looking at the cause-effect relationship between the economic, financial, demographic and food crises. Crises are interrelated and need to be viewed together, as the effects of one crisis are or may represent causes for another crisis. The current food crisis translates today in food price increases, in the level of health of the population that does not have enough resources for a balanced diet and in obesity problems of the young generation (Romania ranks third among European countries. All these issues with immediate and direct effects over the population in our country have generated our interest to conduct a rigorous and careful observation on the development of the phenomenon of food crisis. Food crisis, its causes and consequences – aging population, the migration of the active population to other countries (especially from the rural areas and the agglomeration of the disadvantaged population in certain geographical areas, can cause social and economic imbalances.

Economic theory has to be radically reinvented to squarely face the reality of rising unemployment, widening inequalities, growing ecological threats, frustrated social aspirations and unmet human needs. Monetary and fiscal policies are too crude and insufficient to steer the essential change of course required to address multidimensional demographic, ecological, economic, political and social crises. New values are needed to guide policy formulation and new institutions are needed to support peaceful social evolution and inclusive, equitable development in an increasingly globalized and interconnected world.

    Highlights: • We studied a dissipative bouncing ball dynamics. • A two-dimensional nonlinear mapping describes the dynamics. • Crises between attractors and its manifolds were characterized. • A new physical crisis between vibrating platform and an attractor was characterized. • The existence of a ‘robust’ chaotic attractor was set. - Abstract: The dynamics of a bouncing ball model under the influence of dissipation is investigated by using a two-dimensional nonlinear mapping. When high dissipation is considered, the dynamics evolves to different attractors. The evolution of the basins of the attracting fixed points is characterized, as we vary the control parameters. Crises between the attractors and their boundaries are observed. We found that the multiple attractors are intertwined, and when the boundary crisis between their stable and unstable manifolds occurs, it creates a successive mechanism of destruction for all attractors originated by the sinks. Also, a physical impact crisis is described, an important mechanism in the reduction of the number of attractors.

Although, olanzapine, which is an SGA, has a high risk of causing weight gain, metabolic syndrome, raised blood sugar, and dyslipidemias; it is widely used as the risk of developing extrapyramidal syndromes (EPS is low. Among the various forms of EPS, tardive syndromes are the most feared, tardive dyskinesia, tardive akathisia, and tardive dystonia are the commonest tardive syndromes, the others being less common. Tardive oculogyric crises (TOC are a rare form of tardive dystonia. This patient had TOC with prolonged unsupervised treatment with low-dose olanzapine. Added to that, she developed weight gain that was alarmingly high and such high gain in weight with olanzapine, to our knowledge, has not been reported.

    How economic crises impact the boundaries of firms has been offered virtually no attention in the literature on the theory of the firm. I review the best-known theories of the firm and identify the variables that matter for the explanation of firm boundaries.

    Stress during volcanic crises is high, and any friction between scientists can distract seriously from both humanitarian and scientific effort. Friction can arise, for example, if team members do not share all of their data, if differences in scientific interpretation erupt into public controversy, or if one scientist begins work on a prime research topic while a colleague with longer-standing investment is still busy with public safety work. Some problems arise within existing scientific teams; others are brought on by visiting scientists. Friction can also arise between volcanologists and public officials. Two general measures may avert or reduce friction: (a) National volcanologic surveys and other scientific groups that advise civil authorities in times of volcanic crisis should prepare, in advance of crises, a written plan that details crisis team policies, procedures, leadership and other roles of team members, and other matters pertinent to crisis conduct. A copy of this plan should be given to all current and prospective team members. (b) Each participant in a crisis team should examine his or her own actions and contribution to the crisis effort. A personal checklist is provided to aid this examination. Questions fall generally in two categories: Are my presence and actions for the public good? Are my words and actions collegial, i.e., courteous, respectful, and fair? Numerous specific solutions to common crisis problems are also offered. Among these suggestions are: (a) choose scientific team leaders primarily for their leadership skills; (b) speak publicly with a single scientific voice, especially when forecasts, warnings, or scientific disagreements are involved; (c) if you are a would-be visitor, inquire from the primary scientific team whether your help would be welcomed, and, in general, proceed only if the reply is genuinely positive; (d) in publications, personnel evaluations, and funding, reward rather than discourage teamwork.

    Sickle cell disease patients who acquire iron deficiency may experience a degree of amelioration from painful crises in terms of frequency, severity, and duration. This observation prompted us to identify the potential utility of iron load reduction in the management of this disease. Thirteen sickle cell patients not ameliorated by conventional treatment entered a weekly venesection protocol. Hematological values and painful crises of all degrees of severity were recorded and compared to those of the last 12 months before venesection for each case separately ("historical controls"). A decrease was noted in the frequency and intensity of several types of painful crises. Reduction of iron load by venesection seems to be a simple, safe, side-effect-free, and efficient way of preventing and ameliorating to a large extent painful crises in sickle cell disease. The biological effects of venesection on other parameters of sickle cell disease remain to be determined.

  10. Reassessing Wheat Crises in Eighteenth-century Thessaloniki

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Wheat crises and local riots in eighteenth-century Thessaloniki are not unknown to scholars. However, all the relative conclusions are based mostly on Svoronos' and Iliadou's indexes rather than on additional research of primary sources. Therefore, much space has been given to speculation and various issues have been left without proper examination. This paper seeks to explore, through the study of the French consular correspondence, if there was a common pattern in all wheat crises; why did not all crises develop into open revolts; and, who were the basic participants in the making and management of the crises. It asserts that the development of wheat shortages into popular riots was the outcome of local commercial interests and calculated petty politics, not of famine.

    We discuss some open problems concerning the origin and the emission mechanism of gamma-ray bursts (GRBs) in light of recent developments. If GRBs originate at extragalactic distances, we are facing four crises: (1) an energy crisis, models have to account for more than 10^{53} ergs of energy emitted in the gamma-ray energy band; (2) a spectral crisis, emission models have to account for the surprising `smoothness' of GRB broad-band spectra, with no indication of the predicted spectral `distorsions' caused by inverse Compton scattering in large radiation energy density media, and no evidence for beaming; (3) an afterglow crisis, relativistic shock models have to explain the complexity of the afterglow behavior, the longevity of optical transients detectable up to six months after the burst, the erratic behavior of the radio emission, and the lack of evidence for substantial beaming as indicated by recent searches for GRB afterglows in the X-ray band; (4) a population crisis, from data clearly indicating that ...

    Full Text Available O presente estudo tem como objetivo analisar a crise do meio ambiente sob uma abordagem epistemológica, ou seja, a partir do conhecimento produzido em relação à natureza. Verifica-se que o pensamento ocidental, manifestado pelos paradigmas da Ciência Moderna, está ligado à organização dos sistemas econômicos que reconheceram historicamente a natureza apenas como recurso e potencial de produção de capital, vindo a encontrar, por esta via, o limite entrópico da biosfera e, por conseguinte, do crescimento. Abordou-se o processo de construção do conhecimento, questionando-se a possibilidade de concepção de outras perspectivas, fundadas na inseparabilidade entre sujeito-objeto, ação-pensamento e homem-natureza. É percebida a necessidade do ser humano de se re-significar no mundo, conhecendo a complexidade da natureza e pensando além da crise ecológica.

  15. Stochastic Modelling of Past Volcanic Crises

    Science.gov (United States)

    Woo, Gordon

    2017-04-01

    It is customary to have continuous monitoring of volcanoes showing signs of unrest that might lead to an eruption threatening local populations. Despite scientific progress in estimating the probability of an eruption occurring, the concept of continuously tracking eruption probability remains a future aspiration for volcano risk analysts. During some recent major volcanic crises, attempts have been made to estimate the eruption probability in real time to support government decision-making. These include the possibility of an eruption of Katla linked with the eruption of Eyjafjallajökull in 2010, and the Santorini crisis of 2011-2012. However, once a crisis fades, interest in analyzing the probability that there might have been an eruption tends to wane. There is an inherent outcome bias well known to psychologists: if disaster was avoided, there is perceived to be little purpose in exploring scenarios where a disaster might have happened. Yet the better that previous periods of unrest are understood and modelled, the better that the risk associated with future periods of unrest will be quantified. Scenarios are counterfactual histories of the future. The task of quantifying the probability of an eruption for a past period of unrest should not be merely a statistical calculation, but should serve to elucidate and refine geophysical models of the eruptive processes. This is achieved by using a Bayesian Belief Network approach, in which monitoring observations are used to draw inferences on the underlying causal factors. Specifically, risk analysts are interested in identifying what dynamical perturbations might have tipped an unrest period in history over towards an eruption, and assessing what was the likelihood of such perturbations. Furthermore, in what ways might a historical volcano crisis have turned for the worse? Such important counterfactual questions are addressed in this paper.

    To further our understanding of how to enhance student science and risk communication skills in natural hazards and earth science courses, we conducted a pilot study to assess the different perceptions of expert scientists and risk communication practitioners versus the perceptions of students. These differences will be used to identify expert views on best practice, and improve the teaching of communication skills at the University level. In this pilot study, a perceptions questionnaire was developed and validated. Within this, respondents (geoscientists, engineers, and emergency managers; n=44) were asked to determine their agreement with the use and effectiveness of specific communication strategies (within the first 72 hours after a devastating earthquake) when communicating to the public. In terms of strategies and information to the public, the respondents were mostly in agreement, but there were several statements which elicited large differences between expert responses: 1) the role and purpose of the scientific communication during crises (to persuade people to care, to provide advice, to empower people to take action); 2) the scientist's delivery (showing the scientists emotions and enthusiasm for scientific concepts they are discussing); and 3) the amount of data that is discussed (being comprehensive versus 'only the important' data). The most disagreed upon dimension was related to whether to disclose any political influence on the communication. Additionally, scientists identified that being an effective communicator was an important part of their job, and agreed that it is important to practice these skills. Respondents generally indicated that while scientists should be accountable for the science advice provided, they should not be held liable.

    2016-09-01

    The present study is a systematic review of empirical literature from the last 35 years on families' responses to economic distress in the context of macroeconomic crises. Thirty-nine studies published between 1983 and 2015 in 12 countries were identified, resulting in 3 main findings. First, economic distress was associated with negative changes in family dynamics, specifically couple relationships and parenting. Second, protective factors were found to buffer the adverse effects of economic distress on family and individual outcomes. Third, the results suggest that individual responses to macroeconomic crises may be moderated by sex. Implications for future research encompass using validated assessment instruments, including participants beyond 2-parent families with adolescent children and conducting both longitudinal and qualitative studies that focus on the processes and meanings of adaptation within this risk context. Conclusions highlighted the need to assist families dealing with macroeconomic crises' demands, encouraging the development and validation of macrosystemic intervention programs.

  20. The benefits of flexible team interaction during crises.

    Stachowski, Alicia A; Kaplan, Seth A; Waller, Mary J

    2009-11-01

    Organizations increasingly rely on teams to respond to crises. While research on team effectiveness during nonroutine events is growing, naturalistic studies examining team behaviors during crises are relatively scarce. Furthermore, the relevant literature offers competing theoretical rationales concerning effective team response to crises. In this article, the authors investigate whether high- versus average-performing teams can be distinguished on the basis of the number and complexity of their interaction patterns. Using behavioral observation methodology, the authors coded the discrete verbal and nonverbal behaviors of 14 nuclear power plant control room crews as they responded to a simulated crisis. Pattern detection software revealed systematic differences among crews in their patterns of interaction. Mean comparisons and discriminant function analysis indicated that higher performing crews exhibited fewer, shorter, and less complex interaction patterns. These results illustrate the limitations of standardized response patterns and highlight the importance of team adaptability. Implications for future research and for team training are included.

    2016-05-01

    This paper examines the effects of financial crises on foreign exchange (FX) markets, where entropy evolution is measured for different exchange rates, using the time-dependent block entropy method. Empirical results suggest that financial crises are associated with significant increase of exchange rate entropy, reflecting instability in FX market dynamics. In accordance with phenomenological expectations, it is found that FX markets with large liquidity and large trading volume are more inert - they recover quicker from a crisis than markets with small liquidity and small trading volume. Moreover, our numerical analysis shows that periods of economic uncertainty are preceded by periods of low entropy values, which may serve as a tool for anticipating the onset of financial crises.

    2011-06-01

    Full Text Available An increase in the frequency and intensity of environmental crises associated with accelerating human-induced global change is of substantial concern to policy makers. The potential impacts, especially on the poor, are exacerbated in an increasingly connected world that enables the emergence of crises that are coupled in time and space. We discuss two factors that can interact to contribute to such an increased concatenation of crises: (1 the increasing strength of global vs. local drivers of change, so that changes become increasingly synchronized; and (2 unprecedented potential for the propagation of crises, and an enhanced risk of management interventions in one region becoming drivers elsewhere, because of increased connectivity. We discuss the oil-food-financial crisis of 2007 to 2008 as an example of a concatenated crisis with origin and ultimate impacts in far removed parts of the globe. The potential for a future of concatenated shocks requires adaptations in science and governance including (a an increased tolerance of uncertainty and surprise, (b strengthening capacity for early detection and response to shocks, and (c flexibility in response to enable adaptation and learning.

    1999-06-01

    Full Text Available Phenytoin is an effective antiepileptic drug, although, it can be associated with many side effects, including dyskinesia. OBJECTIVE: To describe the clinical characteristics of phenytoin induced dyskinesia. METHODS: We investigated the occurrence of involuntary movements in patients followed at our adult and pediatric epilepsy clinics during the period of one year. RESULTS: Three patients presented with phenytoin-induced dyskinesia: one adult with axial and orofacial dyskinesia, and two children with choreoathetosis. They did not have other signs of phenytoin intoxication and had complete recovery after phenytoin withdrawal. CONCLUSION: Phenytoin induced dyskinesia may occur during either chronic or initial treatment and with normal serum phenytoin levels. However, it occurs most often in patients on polytherapy, usually after increasing dosage and with toxic serum levels. Other signs of phenytoin intoxication may be present in these patients, but often the dyskinesia is the only side effect, which may delay the diagnosis and treatment. The clinical characteristics of the involuntary movements vary and may be focal or generalized, most often characterized by choreoathetosis and dyskinesias. These may last for hours, days or even years, but frequently disappear completely after phenytoin withdrawal.Fenitoína é droga anti-epiléptica eficaz, mas pode estar associada a vários efeitos colaterais, inclusive discinesia. OBJETIVO: Descrever as características clínicas da discinesia induzida por fenitoína. MÉTODO: Avaliamos a ocorrência de movimentos involuntários em pacientes seguidos nos ambulatórios de epilepsia durante o período de um ano. RESULTADOS: Três pacientes apresentaram discinesia induzida por fenitoína: um adulto com discinesia orofacial e duas crianças com coreoatetose. Eles não tinham outros sinais de intoxicação por fenitoína e apresentaram recuperação completa após a retirada da fenitoína. CONCLUSÃO: Discinesia

MÉTODOS: A hiperalgesia foi estudada através da indução de uma ceratite inflamatória em ratos (n = 60, pela exposição da córnea ao LPS (LPS +. Após a exposição, os olhos foram tratados durante quatro dias, com as soluções tópicas: DNI (200 mg, 65 mg e 20 mg, prednisolona 1% (PRED ou Veículo. Olhos controles foram expostos apenas à solução salina (LPS -. Para avaliar a dor ocular, contouse o número de piscadas em 40 segundos, após instilação de uma gota de capsaicina 0,01 mM. A análise histopatológica foi realizada para avaliação da infiltração neutrofílica. RESULTADOS: Foram observadas áreas esbranquiçadas no estroma corneano dos olhos com a ceratite induzida pelo LPS, entre os dias 3 e 15 dias. Esses olhos (LPS + apresentaram um número significativamente maior de piscadas que os LPS - (P = 0,019 à estimulação química. O tratamento tópico com o DNI reduziu o número de piscadas observadas (P = 0,010. Da mesma forma, olhos expostos ao LPS e tratados com DNI demonstraram redução significativa na infiltração neutrofílica (P = 0,0031. CONCLUSÃO: Baixas doses de DNI reduziram a hiperalgesia corneana e a infiltração neutrofílica nesse modelo de ceratite. Dessa forma, doadores de óxido nítrico, como o DNI, poderão ser úteis no futuro ao tratamento clínico de diversas condições dolorosas da superfície ocular.

    Full Text Available In last quarter of 1997, the economic crises came in the East Asian countries. However, the countries those are affected by these crises are Malaysia, South Korea, Indonesia, Japan, Philippians, Thailand and Taiwan. The reason behind these crises were due to miss management of economic system and bankruptcy because mostly bank became corrupt during these crises and real GDP effected by these crises, whereas GDP in some countries are less effected as compared by the remaining countries after the crises in 2000. But the investment ration fell during that period, whereas, a comparative analysis are done in this paper that showed the investment ratio decreased during the period but slightly recovered after the crises. We explored the growth of the Asian economy and determinants of the economic growth before and after the crises. In the first part of the paper, we review the East Asian economy before 1997 while in second part we discuss the crises development of East Asia countries after the crises. The crisis resulted in the stock market values have failed to pre-crisis values retain is supported by the result. A picture of currency and banking crises exhibited a slightly different image study in the result.

    Human conflict, geopolitical crises, terrorist attacks, and natural disasters can turn large parts of energy distribution networks offline. Europe's current gas supply network is largely dependent on deliveries from Russia and North Africa, creating vulnerabilities to social and political instabilities. During crises, less delivery may mean greater congestion, as the pipeline network is used in ways it has not been designed for. Given the importance of the security of natural gas supply, we develop a model to handle network congestion on various geographical scales. We offer a resilient response strategy to energy shortages and quantify its effectiveness for a variety of relevant scenarios. In essence, Europe's gas supply can be made robust even to major supply disruptions, if a fair distribution strategy is applied.

  1. [Political crises in Africa and infant and child mortality].

    Garenne, M

    1997-01-01

    Many African countries experienced severe political crises after independence, and in a number of cases the crises had significant demographic consequences, especially for child mortality. Data based on maternity histories allowed the reconstruction of child mortality trends over the past 20-30 years in Uganda, Ghana, Rwanda, Madagascar, and Mozambique. The indicator used was the child mortality quotient (number of deaths of under-5 children per 1000 births). Uganda's child mortality declined from 227/1000 in 1960 to 154/1000 in 1970, but the trend was reversed in 1971, when Idi Amin Dada came to power, and the rate reached 204/1000 in 1982 before beginning to decline again. The level of mortality remained high, however, and was still 160/1000 in 1988. Ghana suffered a political and economic crisis during 1979-84. Child mortality rose from 130/1000 in 1978 to 175/1000 in 1983. Mortality rates began a rapid decline after structural adjustment programs were begun, possibly due to improved management of health services. The child mortality rate in Rwanda increased from around 220/1000 in 1960 to 240/1000 in 1975, before beginning a decline in the late 1970s that reached 140/1000 by 1990. The period of political stability and relative prosperity during the 15-year reign of Juvenal Habyarimana was associated with the decline. Political crises marked by student and peasant uprisings were associated with Madagascar's child mortality rate increase from about 145/1000 in 1960 to 185/1000 in 1985. Mozambique was beset by civil war after independence, in which destruction of the health infrastructure was a strategy. The child mortality rate increased from 270/1000 to 470/1000 between 1975 and 1986, a peak war year. The factors by which political crises affect mortality so profoundly remain to be explained, but particular attention should be given to studying the health sector.

    Full Text Available Today software projects are important part into almost every business application. It is quality, efficiency and effectiveness of these applications will determine the failure or success of many business solutions. Consequently, businesses often find that they need to have a competitive and efficient advantage through the development and improve of software projects that help critical business activities. The quality of a software project is determined by the quality of the software development process. Improvements in the development process can lead to significant improvement in software quality. Based on the foregoing risks and problems which may be software engineering project faced, we try to shed light on the mechanism of dealing with crises in software engineering projects in this research. This research suggests a set of rules and guidelines that help software project mangers to prevent and dealing with software project crises Also a model was proposed; the proposed model showed a set of steps that must be implemented in case of crises emerging or before it happen. The crisis management starts understanding it first and then to prepare a careful review of her as she is looking for regions or aspects of the turmoil and failures. The next step is the classification of crisis, then the preparation or design a plan attitudinal or contingency plan, which must be implemented immediately upon the occurrence of crisis. Finally, the final element is the implementation of the program or plan established soon after the crisis and it should be noted here that the project team of software engineering that have been trained on the virtual models of various crises, which helps in the development of managed, skills, and also that you should avoid or ignore the failure to acknowledge a problem when Start or try to be underestimated or taken lightly.

    Full Text Available Os casos de três pacientes com crises focais associadas a hiperglicemia não cetótica (HNC são relatados. Os dois primeiros tiveram epilepsia parcial contínua (EPC motora. No primeiro paciente a EPC foi a manifestação inicial do diabetes mellitus. O exame neurológico mostrou-se normal em todos os pacientes. TC de crânio e exame do LCR foram normais, quando realizados. O EEG, durante a EPC em um caso, mostrou atividade critica epileptiforme nas regiões temporais bilateralmente, a despeito da manifestação clínica ser unilateral. Os níveis glicêmicos foram de 455, 660 e 439 mg/dl. Dois pacientes apresentavam hiponatremia concomitante. Nenhum dos pacientes respondeu à hidantalização ou ao uso de benzodiazepínicos; em um deles houve acentuação das crises após sua administração. O controle das crises só ocorreu com insulinoterapia e correção hidroeletrolítica. O reconhecimento da HCN como causa de EPC, sem lesão estrutural evidenciável, é de grande importância no sentido de orientar a terapêutica adequada para o controle das crises e de evitar evolução para síndrome de HNC com hiperosmolaridade e alteração de consciência, o que leva a mortalidade significante.

    This European Psychiatric Association (EPA) guidance paper is a result of the Working Group on Mental Health Consequences of Economic Crises of the EPA Council of National Psychiatric Associations. Its purpose is to identify the impact on mental health in Europe of the economic downturn and the measures that may be taken to respond to it. We performed a review of the existing literature that yields 350 articles on which our conclusions and recommendations are based. Evidence-based tables and recommendations were developed through an expert consensus process. Literature dealing with the consequences of economic turmoil on the health and health behaviours of the population is heterogeneous, and the results are not completely unequivocal. However, there is a broad consensus about the deleterious consequences of economic crises on mental health, particularly on psychological well-being, depression, anxiety disorders, insomnia, alcohol abuse, and suicidal behaviour. Unemployment, indebtedness, precarious working conditions, inequalities, lack of social connectedness, and housing instability emerge as main risk factors. Men at working age could be particularly at risk, together with previous low SES or stigmatized populations. Generalized austerity measures and poor developed welfare systems trend to increase the harmful effects of economic crises on mental health. Although many articles suggest limitations of existing research and provide suggestions for future research, there is relatively little discussion of policy approaches to address the negative impact of economic crises on mental health. The few studies that addressed policy questions suggested that the development of social protection programs such as active labour programs, social support systems, protection for housing instability, and better access to mental health care, particularly at primary care level, is strongly needed.

    RAQUEL DEZIDÉRIO SOUTO

    Full Text Available resumo Diante da crise ambiental atual, diversas disciplinas científicas têm se voltado para sua análise, a fim de apontar soluções para dirimir ou minimizar os danos ambientais e sociais causados pelas atividades econômicas e por outros tipos de fatores de pressão ambiental. Este artigo propõe-se inicialmente a mostrar sucintamente como mudou a visão geográfica predominante no mundo ocidental a respeito da relação entre as populações humanas e o ambiente. Uma mudança de visão que foi reflexo das mudanças que estavam em curso na geografia como um todo, resguardadas as diferenças entre os países. Discute-se ainda que a crise ambiental é uma crise do conhecimento, como afirmam cada vez mais autores. Este texto culmina com as virtudes e limitações da geografia na busca desse entendimento, no intuito de colaborar para seu avançar.

    Full Text Available The paper aims to look into the origin and nature of global economic crises, the least studied phenomena of the global economic life – the phenomena, the nature of which still has not received a generally accepted explanation in economic science. Market economy has its own laws, the spontaneous nature of which is revealed in times of crises. However, the analysis of global “crisis experience” draws attention to an important feature in the implementation of various forms of crises that remains at all the stages of economic development. Some economic shocks, despite their urgency and scale, gradually give way to recovery and then – to complete recovery. Other end up with weak revival and depression, gradually turning into a new recession. Such crises, depressions, and periods of sluggish economic recovery form the “waves of crisis development” that hold the economy in a depressed condition for a long time. The impact and the consequences of these “waves” of economic shocks that are sequential or overlapping in time go beyond the medium-term economic dynamics. They occur within a long-term (Kondratiev cycle and coincide with its descending phase, when, according to empirically confirmed ideas of the great Russian economist Nikolai Kondratiev, the economy is undergoing a difficult stage of the crisis-depression development that shapes the parameters of future economic growth. The present paper unites the economic events of this stage in the concept of “systemic economic crisis”. This concept is introduced for the purpose of structuring in the single economic process the diverse phenomena occurring at the downward phase of the long-term cycle. Each of them may be due to special causes and have a separate history, but initially, all these events are subordinated to the decision of general systemic problems, and for this reason can be considered as part of the single systemic crisis, the overcoming of which provides the rise of the

    Major economic crises tend to be followed by crises in subjective well-being. Following the financial and debt crises, politicians and social scientists have engaged in heated discussions of ways to alleviate such losses. In particular, should governments intervene more or less? This paper explores...... whether liberalizing economic institutions, a type of reform favoured by some economists, is likely to alleviate such loses. Estimating the effects of crises across European states 1975–2011 suggest that countries with relatively easy market regulations suffered smaller well-being losses....

    Full Text Available Este artigo apresenta criticamente diferentes interpretações da crise atual. Orientaram a seleção das várias contribuições a representatividade das teorias marxistas clássicas de crise e a importância das novas abordagens correspondentes aos novos fenômenos em desenvolvimento no capitalismo atual. O exame crítico dessas contribuições revela uma linha divisória entre aqueles que concebem a crise como tendo sido causada pelo afluxo dos lucros da produção para as finanças (Husson e Foster /Magdoff e aqueles para os quais o aumento do crédito de consumo foi resultado de uma reestruturação dos fluxos de crédito das empresas, cada vez mais autônomas no mercado de dinheiro, às famílias assalariadas, cada vez mais dependentes do financiamento bancário. Essa linha divisória reflete a importância que o primeiro grupo adjudica à diminuição do ritmo de crescimento vis-à-vis os teóricos da School of Oriental and African Studies. A análise revela também que a atrofia da economia política leva a um abandono precoce da teoria bancária e financeira de Marx em favor dos instrumentos teóricos pós-keynesianos imediatamente disponíveis para o uso.This article is a critical survey of different interpretations of the 2007-2008 financial crises. They were chosen either because they represented classical Marxian views on crisis, such as the underconsumption or over-accumulation theories, or else because they were newly developed interpretations based on recent newly economic developments, as it is the case of the financial expropriation theory. The analysis reveals three main points of view. The first is that the cause of crisis is the stagnation of the economy and the ensuing transfer of profits from production to finance, process that caused the housing-financial bubble (Husson and Foster/Magdoff. The second view argues that it was the structural change in financial markets which led banks to increasingly rely on consumer credit

    The health effects of recent economic crises differ markedly by population group. The objective of this systematic review is to examine evidence from longitudinal studies on factors influencing resilience for any health outcome or health behaviour among the general population living in countries exposed to financial crises. We systematically reviewed studies from six electronic databases (EMBASE, Global Health, MEDLINE, PsycINFO, Scopus, Web of Science) which used quantitative longitudinal study designs and included: (i) exposure to an economic crisis; (ii) changes in health outcomes/behaviours over time; (iii) statistical tests of associations of health risk and/or protective factors with health outcomes/behaviours. The quality of the selected studies was appraised using the Quality Assessment Tool for Quantitative Studies. PRISMA reporting guidelines were followed. From 14,584 retrieved records, 22 studies met the eligibility criteria. These studies were conducted across 10 countries in Asia, Europe and North America over the past two decades. Ten socio-demographic factors that increased or protected against health risk were identified: gender, age, education, marital status, household size, employment/occupation, income/ financial constraints, personal beliefs, health status, area of residence, and social relations. These studies addressed physical health, mortality, suicide and suicide attempts, mental health, and health behaviours. Women's mental health appeared more susceptible to crises than men's. Lower income levels were associated with greater increases in cardiovascular disease, mortality and worse mental health. Employment status was associated with changes in mental health. Associations with age, marital status, and education were less consistent, although higher education was associated with healthier behaviours. Despite widespread rhetoric about the importance of resilience, there was a dearth of studies which operationalised resilience factors

    Full Text Available This paper examines the effect of economic crises on structural unemployment using an Autoregressive Distributed Lags model and accounting for the role of institutional settings on an unbalanced panel of 30 OECD economies from 1960 to 2006. We found that downturns have, on average, a significant positive impact on the level of structural unemployment rate. The maximum impact varies with the severity of the downturn. Institutions (such as employment protection legislation, average replacement ratio and product market regulation influence both the extent of the initial shock and the adjustment pattern in the aftermath of an economic downturn.

    Erikson (1959) proposed a theoretical basis for healthy psychosocial development. His theory posits eight critical conflict situations throughout one's lifetime, each of which can result in a favorable or unfavorable resolution. Autobiographies, memoirs, interviews, personal diaries, and oral histories of 97 international astronauts were content analyzed to assess reported resolutions of Erikson's psychosocial crises, regardless of chronological sequence. We made comparisons across flight phases (before, during, and after), gender, nationality of home space agency, and flight duration. Astronauts reported more favorable than unfavorable outcomes across flight phases and demographic variables. Differences across demographic variables and flight phases, as well as the changes as a result of the flight are discussed.

  10. Early Warning Models for Systemic Banking Crises in Montenegro

    Željka Asanović

    2013-06-01

    Full Text Available The purpose of this research is to create an adequate early warning model for systemic banking crises in Montenegro. The probability of banking crisis occurrence is calculated using discrete dependent variable models, more precisely, estimating logit regression. Afterwards, seven simple logit regressions that individually have two explanatory variables are estimated. Adequate weights have been assigned to all seven regressions using the technique of Bayesian model averaging. The advantage of this technique is that it takes into account the model uncertainty by considering various combinations of models in order to minimize the author’s subjective judgment when determining reliable early warning indicators. The results of Bayesian model averaging largely coincide with the results of a previously estimated dynamic logit model. Indicators of credit expansion, thanks to their performances, have a dominant role in early warning models for systemic banking crises in Montenegro. The results have also shown that the Montenegrin banking system is significantly exposed to trends on the global level.

    Full Text Available Resumo Este artigo mostra que a crise de 2014/2017 é fruto de uma combinação de choques de oferta e demanda resultado de erros de política econômica. Esses choques produziram uma redução da capacidade de crescimento da economia brasileira e risco de insolvência das finanças públicas. A solução da crise fiscal, através da PEC do teto dos gastos, fará que o país retome o crescimento econômico a partir de 2017, utilizando a capacidade ociosa da economia. No entanto, a taxa de crescimento do produto potencial não recuperará o ritmo anterior devido aos efeitos duradouros das políticas da Nova Matriz Econômica (NME que reduziram o produto potencial nacional. Recomenda-se, portanto, a adoção de políticas que induzam uma recuperação da produtividade da economia brasileira.

La métropolisation, telle que présentée à l’opinion publique, est l’avenir urbain de l’humanité.

    2010-01-01

    Full Text Available There has been much work highlighting the benefits of autoethnographic research yet little acknowledgement of the demands researching your own life makes on the emotional and mental wellbeing of the researcher. This paper explores the consequences that can arise as a result of autoethnographic research by detailing the crises involved in researching a topic that the researcher has experienced herself. This paper discusses the re-emergence of my grief over the death of my mother as I researched into the experience of other young women who had experienced the death of their mother during their youth. The research process was a journey in which crises were experienced that conflicted and illuminated the emerging findings of the research. The role of the researcher and the researcher's subjectivity--emotions, feelings, actions--are highlighted as integral to research practice. Accepting vulnerability and problematic feelings and emotions can be seen both as an important part of grieving the loss of a mother but also a significant step in conducting research and being a researcher.

  14. Improving communication during volcanic crises on small, vulnerable islands

    Increased exposure to volcanic hazard, particularly at vulnerable small islands, is driving an urgent and growing need for improved communication between monitoring scientists, emergency managers and the media, in advance of and during volcanic crises. Information gathering exercises undertaken on volcanic islands (Guadeloupe, St. Vincent and Montserrat) in the Lesser Antilles (eastern Caribbean), which have recently experienced - or are currently experiencing - volcanic action, have provided the basis for the compilation and publication of a handbook on Communication During Volcanic Emergencies, aimed at the principal stakeholder groups. The findings of the on-island surveys point up the critical importance of (1) bringing together monitoring scientists, emergency managers, and representatives of the media, well in advance of a volcanic crisis, and (2), ensuring that procedures and protocols are in place that will allow, as far as possible, effective and seamless cooperation and coordination when and if a crisis situation develops. Communication During Volcanic Emergencies is designed to promote and encourage both of these priorities through providing the first source-book addressing working relationships and inter-linkages between the stakeholder groups, and providing examples of good and bad practice. While targeting the volcanic islands of the eastern Caribbean, the source-book and its content are largely generic, and the advice and guidelines contained therein have equal validity in respect of improving communication before and during crises at any volcano, and have application to the communication issue in respect of a range of other geophysical hazards.

  15. Propagation of crises in the virtual water trade network

    2015-04-01

    The international trade of agricultural goods is associated to the displacement of the water used to produce such goods and embedded in trade as a factor of production. Water virtually exchanged from producing to consuming countries, named virtual water, defines flows across an international network of 'virtual water trade' which enable the assessment of environmental forcings and implications of trade, such as global water savings or country dependencies on foreign water resources. Given the recent expansion of commodity (and virtual water) trade, in both displaced volumes and network structure, concerns have been raised about the exposure to crises of individuals and societies. In fact, if one country had to markedly decrease its export following a socio-economical or environmental crisis, such as a war or a drought, many -if not all- countries would be affected due to a cascade effect within the trade network. The present contribution proposes a mechanistic model describing the propagation of a local crisis into the virtual water trade network, accounting for the network structure and the virtual water balance of all countries. The model, built on data-based assumptions, is tested on the real case study of the Argentinean crisis in 2008-09, when the internal agricultural production (measured as virtual water volume) decreased by 26% and the virtual water export of Argentina dropped accordingly. Crisis propagation and effects on the virtual water trade are correctly captured, showing the way forward to investigations of crises impact and country vulnerability based on the results of the model proposed.

  4. Scenarios for Evolving Seismic Crises: Possible Communication Strategies

    Science.gov (United States)

    Steacy, S.

    2015-12-01

    Recent advances in operational earthquake forecasting mean that we are very close to being able to confidently compute changes in earthquake probability as seismic crises develop. For instance, we now have statistical models such as ETAS and STEP which demonstrate considerable skill in forecasting earthquake rates and recent advances in Coulomb based models are also showing much promise. Communicating changes in earthquake probability is likely be very difficult, however, as the absolute probability of a damaging event is likely to remain quite small despite a significant increase in the relative value. Here, we use a hybrid Coulomb/statistical model to compute probability changes for a series of earthquake scenarios in New Zealand. We discuss the strengths and limitations of the forecasts and suggest a number of possible mechanisms that might be used to communicate results in an actual developing seismic crisis.

    Hypertension is a common clinical problem in the elderly worldwide and physicians of all types are likely to encounter patients with hypertensive urgencies and emergencies in these patients. Although various terms have been applied to these conditions,they are all characterized by acute elevations in blood pressure and evidence of end-organ injury. Prompt, but carefully considered therapy is necessary to limit morbidity and mortality. A wide range of pharmacologic alternatives are available to the practitioner to control blood pressure and treat complications in these patients. The management of the elderly patient with hypertensive crises needs to include close monitoring and a gentle decline in blood pressure to avoid catastrophic complications, exacerbation of ischemic myopathy, and vascular insufficiency.

  6. Economic Crises and the Complexity of Animal Spirits Modeling

    Directory of Open Access Journals (Sweden)

    Grigore PIROŞCĂ

    2011-02-01

    Full Text Available The rationale of this research goes into the origins of the economic crises from a different way of economic thinking, hence the professional interest on bringing again into the light the concept of animal spirits, used for the first time from classic liberals like David Hume, developed by doctrine founder John Maynard Keynes, and captured as groundbreaking economic crisis hypothesis in Nobel Prize laureates’ books like George Akerlof. A familiar account of the last financial crisis underlines the collapse of confidence and evaporation of trust which leaded to failure of corporate governance and easy money policy. Nor were these problems of recent origin; they were rooted in deep structural changes in the economy that date back many years. Financial innovations overheated the world economy and gained steam because of irrational exuberance over a risk free better future. Considering the evidence analyzed in this paper work, this approach of economic crisis through animal spirits puts forward new highlights of economic thought.

    2016-03-01

    Full Text Available Deborah R Stein, Michael A Ferguson Division of Nephrology, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA Abstract: Hypertensive crises in children are medical emergencies that must be identified, evaluated, and treated promptly and appropriately to prevent end-organ injury and even death. Treatment in the acute setting typically includes continuous intravenous antihypertensive medications with monitoring in the intensive care unit setting. Medications commonly used to treat severe hypertension have been poorly studied in children. Dosing guidelines are available, although few pediatric-specific trials have been conducted to facilitate evidence-based therapy. Regardless of what medication is used, blood pressure should be lowered gradually to allow for accommodation of autoregulatory mechanisms and to prevent cerebral ischemia. Determining the underlying cause of the blood pressure elevation may be helpful in guiding therapy.

    The growing dependency of Europe as a whole on energy imports and anticipated further increases in energy prices reinforce the concerns about meeting the energy demand in the future. The objective of the Study is to identify the threats leading to potential energy crises and suggest solutions for facing, in an appropriate way, the related key challenges. In addition, the Study intends to develop a number of indicators effective enough to assess the level of different types of vulnerability, as well the overall vulnerability of a country or region, including threats to physical disruption, higher energy prices etc. The use of vulnerability indicators is highly recommended for all WEC-European countries, as well as to policy makers and market players.

    Full Text Available The remarkable properties of shape memory alloys have been motivating the interest in applications in different areas varying from biomedical to aerospace hardware. The dynamical response of systems composed by shape memory actuators presents nonlinear characteristics and a very rich behavior, showing periodic, quasi-periodic and chaotic responses. This contribution analyses some aspects related to bifurcation phenomenon in a shape memory oscillator where the restitution force is described by a polynomial constitutive model. The term bifurcation is used to describe qualitative changes that occur in the orbit structure of a system, as a consequence of parameter changes, being related to chaos. Numerical simulations show that the response of the shape memory oscillator presents period doubling cascades, direct and reverse, and crises.

  13. Cinacalcet to prevent parathyrotoxic crises in hypercalcaemic patients awaiting parathyroidectomy

    Rostoker, Guy; Bellamy, Jean; Janklewicz, Philippe

    2011-01-01

    Primary hyperparathyroidism is the third most common endocrine disorder. Hypercalcaemia exceeding 3 mmol/l is a major risk factor for parathyrotoxic crises, and management of patients at risk remains a medical challenge. The authors recently managed three such patients referred for severe nephrolithiasis. All had severe hypercalcaemia (at least 3 mmol/l). Instead of the usual management, which involves hospitalisation in an intensive care environment (for about 5–7 days) for rehydration and infusion of intravenous bisphosphonates, followed by emergency parathyroidectomy, the three patients received ambulatory cinacalcet (not an approved indication), 30 mg twice a day. The serum calcium normalised in two cases and declined to a safe level in the third case, allowing minimally invasive parathyroidectomy to be performed at a date chosen according to the patients’ and surgeon’s respective schedules. The authors consider that cinacalcet may benefit severely hypercalcaemic patients awaiting surgery for primary hyperparathyroidism. PMID:22696718

  14. Managing crises through organisational development: a conceptual framework.

    2011-04-01

    This paper presents a synthesis of the guiding principles in crisis management in accordance with the four configurational imperatives (strategy, structure, leadership and environment) defined by Miller (1987) and outlines interventions in organisational development (OD) that may contribute to their achievement. The aim is to build a conceptual framework at the intersection of these two fields that could help to strengthen the resilient capabilities of individuals, organisations and communities to face crises. This incursion into the field of OD--to generate more efficient configurations of practices in crisis management--seems particularly fruitful considering the system-wide application of OD, based on open-systems theory (Burke, 2008). Various interventions proposed by OD in terms of human processes, structural designs and human resource management, as well as strategy, may help leaders, members of organisations and civil society apply effectively, and in a more sustainable way, the crisis management guiding principles defined by researchers.

  16. Evolution, Punctuational Crises and the Threat to Civilization

    Science.gov (United States)

    Clube, S. V. M.

    1996-02-01

    The relationship between “punctuated equilibrium” and “impact crises” is critically examined in the light of our present knowledge of asteroids and comets. It turns out that the emphasis on relatively narrow epochs associated with occasional “NEO” impacts is probably misplaced. Rather priority should be given to the wider and more frequent epochs associated with multiple “NEO” debris impacts which result in so-called “punctuational crises” afflicting the planets. These comprise the global coolings, super-Tunguska events and generally enhanced fireball flux produced by the larger orbital debris whenever an active, dormant or dead comet fragments and produces a trail. Taken as a whole and in conjunction with the target, the response function is inevitably complex. Nevertheless we broadly expect that the strength of a punctuational crisis will vary as the progenitor comet mass, the inverse dispersion of its debris and the inverse delay since fragmentation. The encounter of P/SL-9 with Jupiter may be taken as representing an extreme punctuational crisis where the dispersion and delay were exceptionally small. The more familiar crises affecting the Earth with less extreme values of dispersion and delay, which have resulted in civilization being disturbed a good many times during recent millennia, are no less important however. Indeed, the next such threat to civilization ostensibly has a roughly 1 in 4 lifetime chance. Any support for the Spaceguard programme which detracts from consideration of these punctuational crises, whatever their strength, would seem now to be peculiarly wide of the mark.

  17. Coping with Financial Crises: Latin American Answers to European Questions

    Directory of Open Access Journals (Sweden)

    Eduardo A.Cavallo

    2013-06-01

    Full Text Available Europe faces challenges reminiscent of Latin American financial crises, namely unsustainable sovereign spreads, banking system distress, sudden stops in capital flows and growth rate collapse. The failure of recent liquidity support to normalize the situation suggests the need to refocus the policy debate on fundamentals: structural reform for growth and, where needed, restructuring to resolve banking crises and the debt overhang.  Latin America’s experience yields relevant policy lessons for Europe on all these fronts, tempered only by the slight exception that sharp real devaluation, which was key to spearheading recovery in Latin America, is unfeasible in the eurozone. Struggling eurozone countries are caught between a rock and a hard place, as the currency union imposes strict policy constraints while the reintroduction of national currencies under conditions of crisis would be catastrophic. Nevertheless, contemporary Europe stands a better chance of recovery because, in contrast with the Latin America experience, the European Union possesses greater avenues for international cooperation. With respect to financial support, a resourceful European Central Bank able to avoid chaotic adjustment by brute force is a decisive advantage of Europe relative to Latin America, which only had access to the weaker and less reliable IMF. Arguably, the limited nature of external support strongly contributed to the depth of Latin America’s great collapses. European cooperation can explore and exhaust alternatives to a euro exit to the benefit of all union members and, if dissolution becomes unavoidable, ensure amicable support to ease the transition. The path to success remains uncharted, however, and implementation of the necessary regional mechanisms will require innovation and political will. If the available means of cooperation are not used effectively, crisis countries in Europe may fare worse than those in Latin America.

    2015-01-01

    Full Text Available New analyses of food crises in West Africa. The issue of crisis is a central element of debate and a strategic challenge for all stakeholders in West Africa. Food and nutrition crises are recurrent in the region, with a level of intensity and high variability constituting renewed challenges. The definition, delimitation and management of these crises are provided by an established and structured professional field, which favors intervention. Different conceptual and contextual approaches can be mobilized to account for the diversity and complexity of food and nutrition crises. Some more descriptive approaches list the causes and manifestations of these crises, while others insist on the fact that they are created, and identify their dynamic as being linked to interactions between various phenomena. To date, most of the various institutional actors involved in addressing food and nutrition crises, both at national and international levels, have favored the gradual improvement of expert systems providing technical short-term responses. In parallel, this has led to a harmonization of these frameworks of thought, which has been detrimental to the consideration of the diversity of questions and the integration of non-institutional actors. These are the boundaries and limitations that this article aims to question, in order to reinvoke the political dimension of the management of food crises (and their eventual resolution.

    We first argue about the similarity between the propagation phenomenon of negative information about potential deterioration of economic situation in group of investors and the propagation phenomenon of infectious disease in crowd Applying the negative-information-propagation-induced model built based on above argument, we investigate the relationship between the generation of financial crises and propagation effects of negative information We introduce the discrimination parameter to distinguish whether or not negative information will be propagated extensively in group of investors. We also introduce the target critical value of financial crises. By comparing the theoretically predicted ratio of the long term projected number of total investors to the total number of investors at some time as initial time with target critical value of financial crises, the model can provide real-time monitoring of whether the curve of total number of investors is progressing toward the direction of generating financial crises or running on track of financial markets safety. If at some time this ratio is computed to be less than the target critical value of financial crises, governments can take relevant measures to prevent the generation of financial crises in advance Governments' interference helps to recover the confidence of investors so that they never will again believe in negative information to continue their investment. Results from theoretical and numerical analysis show that the number of investors who hold the belief of potential deterioration of economic situation, and the number of investors who withdraw capital and depart from financial markets for avoiding business loss when governments make appropriate interference are lowered compared to that without appropriate governments' interference. The results show the effectiveness of governments in preventing financial crises from the viewpoint of the negative information-propagation-induced model, namely governments

Esse ensaísmo produziu alguns textos que se transformaram, por meio da crítica, em clássicos da reflexão sobre o país - tais como Radiografía de la pampa, de Ezequiel Martínez Estrada, e Historia de una pasión argentina, de Eduardo Mallea -, e que se gestaram sobre a base de uma crise política - sua primeira exteriorização foi o golpe de Estado de 1930 - e de uma desordem mais ampla dos pontos intelectuais de referência, em consequência da falência do positivismo entre as elites culturais. O dissabor provocado pelo contexto político nacional se mesclou ao mal-estar oriundo do pensamento europeu sobre a crise - crise do espírito, da ordem liberal e do capitalismo -, e esse amálgama alimentou um estado de descontentamento intelectual que ganhou forma na reflexão ensaística. De modo cada vez mais amplo, esse gênero dá início a uma rigorosa revisão da Argentina liberal, no âmbito de cuja produção destacam-se os referidos ensaios de Martínez Estrada e de Mallea, que serão analisados na parte final do presente estudo.This study analyzes a sector of Argentine thought from the 1930s, represented in the essays on the national 'soul' or character.

    Full Text Available Social and cultural anthropologists have made a unique, relevant and anti-normative contribution to the study of crises. By means of ethnographic fieldwork in specific settings, anthropologists have provided significant information on how social groups try to cope with critical situations in everyday life resorting to different strategies, forms of cooperation or political action. Simultaneously, anthropology has brought to light the role played by cognitive schemata and symbolic resources in making sense of crisis situations, turning them intelligible and developing possible resolutions. Anthropology has carried out important studies on how people experience time, give meaning to and produce plausible images of the future in crisis situations, when time freezes. The main theoretical contributions to the study of crises will be discussed, together with a number of empirical studies among which special attention will be paid to those carried out in Latin America, including my own research on the experiences and responses of the middle class during the 2001 Argentine crisis.   Resumen Los antropólogos sociales y culturales han hecho una contribución única, relevante y anti-normativa a los estudios de crisis.

  14. Multiple crises and global health: new and necessary frontiers of health politics.

    Schrecker, Ted

    2012-01-01

    The world economy is entering an era of multiple crises, involving finance, food security and global environmental change. This article assesses the implications for global public health, describes the contours of post-2007 crises in food security and finance, and then briefly indicates the probable health impacts. There follows a discussion of the crisis of climate change, one that will unfold over a longer time frame but with manifestations that may already be upon us. The article then discusses the political economy of responses to these crises, noting the formidable obstacles that exist to equitable resolution. The article concludes by noting the threat that such crises present to recent progress in global health, arguing that global health researchers and practitioners must become more familiar with the relevant social processes, and that proposed solutions that neglect the continuing importance of the nation-state are misdirected.

    Why did some countries learn to grow up to financial stability and others not? We explore this question by surveying the key determinants and major policy responses to banking, currency, and debt crises between 1880 and present. We divide countries into three groups: leaders, learners, and non-learners. Each of these groups had very different experiences in terms of long-run economic outcomes, financial development, financial stability, crisis frequency, and their policy responses to crises. ...

  3. The impact of economic crises on social inequalities in health: what do we know so far?

    Bacigalupe, Amaia; Escolar-Pujolar, Antonio

    2014-07-25

    Since 2008, Western countries are going through a deep economic crisis whose health impacts seem to be fundamentally counter-cyclical: when economic conditions worsen, so does health, and mortality tends to rise. While a growing number of studies have presented evidence on the effect of crises on the average population health, a largely neglected aspect of research is the impact of crises and the related political responses on social inequalities in health, even if the negative consequences of the crises are primarily borne by the most disadvantaged populations. This commentary will reflect on the results of the studies that have analyzed the effect of economic crises on social inequalities in health up to 2013. With some exceptions, the studies show an increase in health inequalities during crises, especially during the Southeast Asian and Japanese crises and the Soviet Union crisis, although it is not always evident for both sexes or all health or socioeconomic variables. In the Nordic countries during the nineties, a clear worsening of health equity did not occur. Results about the impacts of the current economic recession on health equity are still inconsistent. Some of the factors that could explain this variability in results are the role of welfare state policies, the diversity of time periods used in the analyses, the heterogeneity of socioeconomic and health variables considered, the changes in the socioeconomic profile of the groups under comparison in times of crises, and the type of measures used to analyze the magnitude of social inequalities in health. Social epidemiology should further collaborate with other disciplines to help produce more accurate and useful evidence about the relationship between crises and health equity.

  4. Impact of the topology of global macroeconomic network on the spreading of economic crises.

    Throughout economic history, the global economy has experienced recurring crises. The persistent recurrence of such economic crises calls for an understanding of their generic features rather than treating them as singular events. The global economic system is a highly complex system and can best be viewed in terms of a network of interacting macroeconomic agents. In this regard, from the perspective of collective network dynamics, here we explore how the topology of the global macroeconomic network affects the patterns of spreading of economic crises. Using a simple toy model of crisis spreading, we demonstrate that an individual country's role in crisis spreading is not only dependent on its gross macroeconomic capacities, but also on its local and global connectivity profile in the context of the world economic network. We find that on one hand clustering of weak links at the regional scale can significantly aggravate the spread of crises, but on the other hand the current network structure at the global scale harbors higher tolerance of extreme crises compared to more "globalized" random networks. These results suggest that there can be a potential hidden cost in the ongoing globalization movement towards establishing less-constrained, trans-regional economic links between countries, by increasing vulnerability of the global economic system to extreme crises.

    2010-12-01

    The perception, acceptability and management of risks are social construction. Consequently, in managing public health crises, the gap between facts, beliefs and feelings tests the responsiveness of official institutions to health alarms that can be objective, potential, or imaginary. On balance, a strong point of the Spanish experience of health crises is the presence of clinicians and public health officers working in an organization capable of responding adequately, although the quasi-federal Spanish political structure has both advantages and disadvantages. Weaknesses include the low profile given to public health and a management structure that relies too heavily on partitocracy. The management of these crises could be improved by transferring greater scope to health professionals in decisions about crisis identification and management (with transparency) and limiting bureaucratic inertia. For some, health crises involve visibility or business opportunities (not always legitimate). Therefore, the perception of crisis will increasingly rest less in the hands of experts and more in those of groups interested in spreading these crises or in providing solutions. While progress is needed to develop participation in strategies to respond to emerging crises, even more essential is the involvement of all healthcare levels in their preparation and dissemination.

    Historical and contemporary experience suggests that science plays an increasingly critical role in governmental and institutional responses to major environmental crises. Recent examples include major western wildfires (2009), the Deepwater Horizon oil spill (2010), the Fukushima nuclear accident (2011), and Hurricane Sandy (2012). The application of science during such crises has several distinctive characteristics, as well as essential requirements if it is to be useful to decision makers. these include scope conditions that include coupled natural/human systems, clear statement of uncertainties and limitations, description of cascading consequences, accurate sense of place, estimates of magnitude of impacts, identification of beneficiaries and those adversely affected, clarity and conciseness, compelling visualization and presentation, capacity to speak "truth to power", and direct access to decision makers. In this chapter, we explore the role and significance of science – including all relevant disciplines and focusing attention on the social sciences – in responding to major environmental crises. We explore several important questions: How is science during crisis distinctive? What social science is most useful during crises? What distinctive characteristics are necessary for social science to make meaningful contributions to emergency response and recovery? How might the social sciences be integrated into the strategic science needed to respond to future crises? The authors, both members of the Department of the Interior's innovative Strategic Sciences Group, describe broad principles of engagement as well as specific examples drawn from history, contemporary efforts (such as during the Deepwater Horizon oil spill), and predictions of environmental crises still to be confronted.

    Heinrich, K; Walter, C

    1995-01-01

    On the occasion of a rather incidental visit in the sanatorium "Berghof" at Davos, Hans Castorp, the--as to his primary personality--asthenic and low-profile protagonist of the "Zauberberg" is gradually getting caught up in the maelstrom of the there prevailing timelessness and irresponsibility, this being interrupted solely by two tapering to crisis episodes: his amouressness to Mme. Chauchat as an erotic crisis and by the visionary daydream during a snowstorm about the abilities of men as a cognitive, mental crisis. Both events are triggered by a pathoid irritability, following the maxim of Th. Mann that illness, decay and death as borderline experiences may be the presupposition for cognition and reversal. Both crises end without consequences--the "Zauberberg" is the negation of the novel of education and development in the narrower sense. The unsuccessfulness and undecidedness of Hans Castorp's existence culminate in the open end of the novel, regarding his surviving on the battle field, and is in strict contrast to Adrian Leverkühn's determined autoinfection with Lues with the aim of artistic perfection and the creative break-through of "Doctor Faustus". Hans Castorp's regression and self-fragmentation within the decadent-morbid atmosphere of the sanatorium lead to his storming into the battles of the First World War as a last and existential crisis; it is here where finally the individual and national fate are merging. Hans Castorp becomes the paradigma of the German pre-war bourgeoisie and its crisis-prone development.

    2011-08-01

    Neonatal cardiomyopathies due to mitochondrial oxidative phosphorylation (OXPHOS) defects are extremely severe conditions which can be either isolated or included in a multi-organ disease, with or without metabolic crises, of which profound lactic acidosis is the prominent feature. Cardiomyopathy is more often hypertrophic than dilated. Antenatal manifestations such as fetal cardiomyopathy, arrhythmia and/or hydrops have been reported. Pathophysiological mechanisms are complex, going beyond ATP deficiency of the high-energy-consuming neonatal myocardium. Birth is a key metabolic period when the myocardium switches ATP production from anaerobic glycolysis to mitochondrial fatty acid oxidation and OXPHOS. Heart-specificity of the defect may be related to the specific localization of the defect, to the high myocardium dependency on OXPHOS, and/or to interaction between the primary genetic alteration and other factors such as modifier genes. Therapeutic options are limited but standardized diagnostic procedures are mandatory to confirm the OXPHOS defect and to identify its causal mutation, allowing genetic counseling and potential prenatal diagnosis.

A partir de algumas ferramentas da análise do discurso foucaultiana, discute-se um dos enunciados que compõe o discurso aqui investigado: o “Terror e medo pela perda do Planeta”. O estudo toma como corpus discursivo a revista Veja, especialmente reportagens produzidas a partir de 2001, em que enunciações ocupadas por terror e medo se tornam evidentes na mídia em análise. Discussões acerca do medo em Zigmunt Bauman, biopoder/biopolítica em Michel Foucault e cultura a partir de estudiosos do campo da Educação Ambiental são tomados como aportes teóricos desse estudo. Nas reportagens em evidência, há um forte chamamento para riscos e perigos quanto à continuidade de vida na Terra atrelado ao convite para que participemos da grande campanha mundial. Pensarmos possibilidades de enfrentar medos líquidos modernos, produzindo outros modos de nos relacionarmos com o ambiente, é um dos desafios dessa pesquisa.

    The importance of animal health crises has considerably increased over the last few years. When a crisis occurs, farmers can receive financial support through various public, private and mixed compensation schemes. Economic losses resulting from diseases may be direct and indirect. If a disease is covered by European Union regulations then countries have a legal obligation to partly compensate farmers for direct losses, either directly through the national budget, or through a specific fund. The European Veterinary Fund also co-finances these losses. Only a few countries provide compensation for indirect losses. The private insurance sector also provides protection against some direct and indirect losses but the risks covered are variable. To encourage farmers to subscribe to this kind of insurance, some public authorities provide subsidies to help pay the premium. Insurance companies do not generally cover the risks linked to contagious diseases, but some companies do extend cover to include this type of risk. Several alternatives, such as mutual funds, are available to improve risk coverage. There is a lack of harmonisation among the various compensation schemes of different countries. Public authorities cannot provide full compensation, but mutual funds and private insurance companies are alternatives that should be further investigated and their use should be extended to other countries. A classification of diseases would harmonise the situation at the European level.

Loin d’avoir réglé les problèmes structurels, elle témoigne cependant d’une évolution significative des rapports entre l’outre-mer et l’Hexagone.The social crisis which recently shook the French West Indies legitimises the return of the “social question” on the insular political scenes.

    Full Text Available Realities of today have defined a new stage of development which can be characterized as the entry of world economic system in a condition of crisis. Recognizing that development of economic systems means continuous violation of macroeconomic balance - a necessary condition of development. In this context transition processes are considered as a natural, state of society and economy in the course of its evolution. Characteristic feature of a market economy is recurrence of economic development. Recurrence is a form of development of economy as whole, the movement from one macroeconomic balance to another. Recurrence can be as one of ways of self-regulation of market economy. As line of recurrence is the movement not around, and on a spiral, it likes a form of progressive development. The main phase of a business cycle is crisis during which the broken proportions of a social production are restored. For crisis the following signs are characteristic: growth of mass of unrealized production; increase of loan percent; decrease in the share price, etc. All this is of the capital and control of business activity that leads to falling of profit, crisis of non-payments, and is frequent also to bankruptcy. The article is devoted to research of specific non-uniform economic systems, identification of the factors of heterogeneity promoting development of crises of heterogeneity

    Full Text Available A cisplatina é uma droga antineoplásica altamente efetiva contra vários tipos de cânceres humanos, tais como tumores do testículo e ovário, câncer da cabeça e pescoço e câncer do pulmão. Entretanto, a nefrotoxicidade é um dos principais efeitos colaterais da terapia com a cisplatina. A gravidade da nefrotoxicidade induzida pela cisplatina está relacionada com a concentração de platina nos rins. As evidências mostram que a nefrotoxicidade induzida pela cisplatina é atribuída ao dano oxidativo resultante da geração de radicais livres, e que a administração de antioxidantes é eficiente na inibição destes efeitos colaterais. Uma abordagem alternativa para proteger os roedores dos efeitos colaterais da cisplatina é o uso de conhecidos antioxidantes da dieta. Alguns estudos têm sido realizados para diminuir a peroxidação lipídica e os efeitos citotóxicos induzidos pela cisplatina, com o emprego de antioxidantes da dieta, tais como, selenito de sódio, vitaminas C e E, curcumina e o carotenóide bixina. Nós sugerimos que aqueles antioxidantes da dieta têm efeito nefroprotetor, e que os mecanismos antioxidantes destes compostos deveriam ser explorados durante a quimioterapia com a cisplatina.Cisplatin is a highly effective antineoplastic drug used against several types of human cancers, such as testicular and ovarian tumors; head and neck; and lung cancer. However, nephrotoxicity is one of the most important side-effects of cisplatin therapy. The severity of cisplatin nephrotoxicity is related to platinum concentration in the kidneys. There is a growing amount of evidence that cisplatin-induced nephrotoxicity is ascribed to oxidative damage resulting from free radical generation and that the administration of antioxidants is efficient in inhibiting these side effects. An alternative approach aiming to protect rodents against cisplatin side-effects is the introduction of known dietary antioxidants. Some studies have been

O tempo de exposição à obesidade foi associado com uma redução de colágeno do tipo I no grupo Ob30, quando comparado com o Ob15. A obesidade não afetou a expressão do colágeno tipo III. CONCLUSÃO: Este estudo mostrou que o tempo de exposição à obesidade por 30 semanas induzida por uma dieta rica em gordura insaturada causou uma redução na expressão do colágeno miocárdico tipo I em ratos obesos. No entanto, nenhum efeito foi observado em relação à expressão do colágeno miocárdico tipo III

    Full Text Available Safety and security are the most important issues to tourist while traveling and the first aspect they consider is to be protected from hazards. Emergency planning and preparedness for a crisis are the most significant components of dealing with disasters. Hospitality practitioners noticed a rising number of natural and man-made crises that harm the hospitality industry, regarding its vulnerability to crisis and internal and external hazards. By using secondary data, this study aims to shed some light on this issue, contributing to knowledge and awareness on emergency preparedness for the hospitality industry. Moreover, the study aims to explain the management’s commitment to adopt, develop, and update emergency plans. The results of this study explain that tourism as an international mobile industry must respond to internal and external hazards such as disease movement and terrorist attacks. Marketing safety is important to promote hotels and tourist destinations to the guests and holiday advisors. Hotels have a long history of being a soft target for terrorist attacks, as can be seen in several accidents that have shaken the hotel industry in the past few decades. Hotels invest a lot to install protective techniques, but terrorists are becoming more organized. Practitioners propose disaster management frameworks using several measurements. Recovery from crisis and learning help business retention that minimizes negative impacts and prevent losses. Finally, evaluation and feedback are very important to overcome the hazards and return to normal, as well as adopting new ideas to deal with emergencies. Single- and double-loop organizational learning should benefit proactive preparedness.

  20. Energy crises and cooperation: Do international institutions matter?

    Science.gov (United States)

    Chakarova, Vessela P.

    The risk of an oil supply disruption still exists. Oil reserves are increasingly concentrated in a handful of unreliable regimes, plagued by piracy and terrorism. Natural disasters and chokepoint incidents have increased in frequency. In addition, oil is expected to remain a significant part of the energy mix up until 2030. By that time Europe will be importing 90% of its oil. Thus, oil supply security will become an increasingly important feature of European politics. One way to counter the noxious consequences of an oil disruption is to cooperate. International cooperation is a critical factor in any type of crisis, however, it is especially important when it comes to a finite, highly concentrated and critical commodity like oil. The lack of coordination might lead to scrambling and oil hoarding, which dramatically exacerbate the crisis. Yet cooperation in the oil issue-area has been the subject of only a few studies, none of which provides a systematic and comprehensive analysis. They are also limited in their scope and findings. This dissertation aims to partially fill this lacuna. It employs a structured focused comparison to study European consumer countries' cooperation in times of oil supply shortages. There have been fifteen such crises since the Second World War, three of which with dramatic consequences for the world economy. The analysis evaluates European cooperative efforts in seven of these cases, starting with the Abadan crisis in 1951. The cases are selected on the basis of their magnitude and economic impact. In particular, I look at intergovernmental negotiations within existing international bodies prior to, during and immediately after the crisis. The findings suggest that institutions are more likely to facilitate interstate cooperation in the presence of a strong leader (a hegemon) - a role, which in the case of the oil issue-area was assumed by the US until the early 1970s.

    Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

    Blood ammonia and glutamine levels are used as biomarkers of control in patients with urea cycle disorders (UCDs). This study was undertaken to evaluate glutamine variability and utility as a predictor of hyperammonemic crises (HACs) in UCD patients. Methods The relationships between glutamine and ammonia levels and the incidence and timing of HACs were evaluated in over 100 adult and pediatric UCD patients who participated in clinical trials of glycerol phenylbutyrate. Results The median (range) intra-subject 24-hour coefficient of variation for glutamine was 15% (8–29%) as compared with 56% (28%–154%) for ammonia, and the correlation coefficient between glutamine and concurrent ammonia levels varied from 0.17 to 0.29. Patients with baseline (fasting) glutamine values >900 µmol/L had higher baseline ammonia levels (mean [SD]: 39.6 [26.2] µmol/L) than patients with baseline glutamine ≤900 µmol/L (26.6 [18.0] µmol/L). Glutamine values >900 µmol/L during the study were associated with an approximately 2-fold higher HAC risk (odds ratio [OR]=1.98; p=0.173). However, glutamine lost predictive significance (OR=1.47; p=0.439) when concomitant ammonia was taken into account, whereas the predictive value of baseline ammonia ≥ 1.0 upper limit of normal (ULN) was highly statistically significant (OR=4.96; p=0.013). There was no significant effect of glutamine >900 µmol/L on time to first HAC crisis (hazard ratio [HR]=1.14; p=0.813), but there was a significant effect of baseline ammonia ≥ 1.0 ULN (HR=4.62; p=0.0011). Conclusions The findings in this UCD population suggest that glutamine is a weaker predictor of HACs than ammonia and that the utility of the predictive value of glutamine will need to take into account concurrent ammonia levels.

    Julio Cesar MAGALHÃES DE OLIVEIRA

    Full Text Available RESUMO Comparado à organização política do Principado, o regime imperial da Antiguidade Tardia obteve um controle muito maior sobre a circulação da informação política em decorrência da centralização do poder e do número ainda maior de funcionários qualificados dedicados a coligir, cotejar e recuperar informações em todo o Império. Ainda assim, a vastidão do Império Romano e a lentidão das comunicações continuavam a representar as principais ameaças ao poder absolutista, especialmente nos momentos de crises políticas, quando a própria ausência de informações oficiais alimentava os canais subterrâneos e incontrolados de notícias. Do ponto de vista da plebe urbana e dos atores políticos locais, o recurso a essas notícias clandestinas que nós chamamos de "boatos" podia representar uma tentativa de avaliar a abertura de oportunidades para a ação em um ambiente político marcado por uma profunda incerteza. O objetivo deste artigo é explorar como a plebe urbana, as facções religiosas ou seus líderes percebiam (e encorajavam a difusão de notícias sobre as mudanças no poder imperial como uma "janela de oportunidades" e como uma forma de organizar uma ação coletiva.

    Full Text Available The occurrence of the most critical international economical and financial crisis of the 21st century brought into the spotlight the damages that crises can bring to our economy. After its burst in the autumn of 2007, the crisis has spread all over the world through the Contagion Effect, and has led to an accelerated and sharp deterioration of economic activity. The effects of the episodes of financial crises have on the real economy seem to be more important and persistent in some specific countries. For this reason we focused our attention upon eight European transition countries and a sample of thirteen financial crises. The aim of this study is to perform an econometric analysis of the effects of episodes of financial crises on real output (GDP for eight economies from Central and Eastern Europe (CEE using an ARDL equation and an impulse response function. The main findings of the paper suggest that, in the case of the CEE economies analyzed, financial crises have an important and long-lasting effect, lowering the real output by about 12-14%.

  12. Global effects of local food-production crises: a virtual water perspective

    Science.gov (United States)

    Tamea, Stefania; Laio, Francesco; Ridolfi, Luca

    2016-01-01

    By importing food and agricultural goods, countries cope with the heterogeneous global water distribution and often rely on water resources available abroad. The virtual displacement of the water used to produce such goods (known as virtual water) connects together, in a global water system, all countries participating to the international trade network. Local food-production crises, having social, economic or environmental origin, propagate in this network, modifying the virtual water trade and perturbing local and global food availability, quantified in terms of virtual water. We analyze here the possible effects of local crises by developing a new propagation model, parsimonious but grounded on data-based and statistically-verified assumptions, whose effectiveness is proved on the Argentinean crisis in 2008-09. The model serves as the basis to propose indicators of crisis impact and country vulnerability to external food-production crises, which highlight that countries with largest water resources have the highest impact on the international trade, and that not only water-scarce but also wealthy and globalized countries are among the most vulnerable to external crises. The temporal analysis reveals that global average vulnerability has increased over time and that stronger effects of crises are now found in countries with low food (and water) availability.

    Odemene, Glory C.

    The Niger Delta crises escalated beyond the borders of the Nigerian nation to become an issue that affected individuals and corporations around the world. This study led to the discovery of how the local crises escalated with international implications. This discovery was accomplished by addressing how the Niger Delta crises escalated from villages to international scenes, with notable impacts on the environment, health, safety, security, and financial segments of local, international, private, and corporate entities. Using Sweeny's crisis decision theory and Lazarus and Folkman's coping theory, the study considered the coping strategies of community members, the decisions, and actions they took in response to the management approaches of the government and the oil and gas companies (OGCs). This qualitative study utilized historical narrative to collect data by interviewing 4 participants who lived and worked in the region during the crises. NVivo was used for manual and automatic coding of data, as well as for categorization and connection of codes. Content analysis of identified codes and categories revealed the themes and trends in the experiences narrated by participants. Findings include the root causes, trend of escalation, and management strategies of the government and the OGCs that influenced the crises. These findings will help to influence policies and practices in the region and enhance effective management of current and emerging conflicts, with possibilities of restoring stability and security in the areas and in the nation at large.

À análise morfológica evidenciou-se que os grupos chalcona e corticóide apresentaram efeitos terapêuticos semelhantes. CONCLUSÃO: A chalcona teve efeito terapêutico na conjuntivite alérgica induzida por ovalbumina.

  15. The Turn Towards Unity: Converting Crises into Opportunities

    2011-10-01

    Full Text Available Human progress is stimulated by external threats and pressures. Values distilled from long experience possess the essential knowledge and power needed for continuous development and evolution. Successive waves of foreign invasions following the collapse of the Roman Empire coalesced the tribes of England into a nation state. Centuries of incessant warfare finally compelled the countries of Western Europe to evolve a regional union within which war has become unthinkable. Most recently, the rising incidence of terrorism has compelled national security institutions to forge a network for global coordination unimaginable during the Cold War. Challenges met are converted into opportunities. Opportunities missed degenerate into problems. All crises are psychological in origin. The remedy always calls for a change of attitude and values. The greatest threats confronting human beings today do not come from external aggressors. They are the result of problems that affect humanity as a whole and can only be addressed collectively by the entire human race. International financial instability, unemployment, terrorism, proliferation of nuclear weapons and climate change are indications that humanity is entering a higher phase in social evolution that compels us to evolve more effective instruments for governance at the global level. No nation or group of nations acting on its own can protect itself from these threats. Effective action to address these issues is unlikely to come from governments whose source of power and very identity are based on national sovereignty and separateness. Mechanisms for global governance will not be effective unless founded upon universally accepted values in fact as well as in principle, a condition violated by the undemocratic character of the UN system. Power relents only in the face of greater power. Power that exceeds that of the five permanent members of the Security Council can only come from representatives of humanity

    Full Text Available OBJECTIVE: The aim of this study is to investigate the effects of pregabalin on the behavior of rats under the influence of ketamine, an NMDA receptor antagonist that mimics the symptoms of schizophrenia. METHODS: Rats were injected with saline or 25 mg/kg ketamine intraperitoneally. After that, behavior modifications were investigated by the evaluation of stereotypy and hyperlocomotion, after treating rats with pregabalin (at doses of 30 mg/kg or 100 mg/kg or placebo (saline solution. RESULTS: The administration of pregabalin reduced ketamine-induced hyperlocomotion. However, neither doses of pregabalin had a significant effect on ketamineinduced stereotypy. CONCLUSION: This is the first study to investigate the effects of pregabalin using an animal model of psychosis. Furthermore, our results indicate that behavioral changes induced by ketamine in rats can be reversed with the use of pregabalin, suggesting its potential to treat psychotic symptoms.OBJETIVO: O presente estudo tem como objetivo investigar os efeitos da pregabalina sobre as alterações comportamentais em ratos induzidas pela cetamina, um antagonista do receptor glutamatérgico NMDA, utilizado em modelos animais de psicose. MÉTODOS:Ratos receberam injeção com solução salina ou cetamina, na dose de 25 mg/kg, com posterior avaliação das alterações comportamentais induzidas, através da avaliação da estereotipia e hiperlocomoção, depois destes ratos terem sido tratados com pregabalina (30 mg/kg ou 100 mg/kg ou placebo. RESULTADOS:A administração de pregabalina reduziu a hiperlocomoção nos ratos sob o efeito da cetamina. No entanto, nenhuma das doses de pregabalina teve efeito significativo sobre a estereotipia induzida pela cetamina. CONCLUSÃO: Este é o primeiro estudo que investiga os efeitos da pregabalina em um modelo animal de psicose.

    2014-09-01

    Full Text Available This paper explores the synchronicity of two mega-crises we are now facing: The BP oil spill and the repercussions of the 2008 financial meltdown. It examines some key common threads in both of these crises. The overarching message is that firms must maintain a culture of social responsibility, must behave in an ethical manner, and must do everything possible to avoid societal harm. The three key lessons to be learned from the twin crises are to consider and mange risk in decision making; minimize conflicts of interest in the hope that executives will then not engage in actions that involve excessive risk to stakeholders; and that government regulation can be beneficial, rather than harmful to business and society – as long as it does not stifle innovation and growth.

    Full Text Available In terms of global tourism business, tourism constantly faces crises that affect its development. At the beginning of the XXI century, several significant crises have had a negative effect on the world tourism industry, starting with the terrorist attacks on the USA, epidemics, the global economic crisis, natural disasters, political crises, etc. Tourism has resulted in the decline in tourism traffic and tourism receipts, with major or minor impacts on global tourism trends. The largest negative effects realized under the influence of global economic crisis, when the indicators of tourism development were poor throughout the world. To adequately manage the crisis in tourism, certain preventive measures are introduced so as to forestall the outbreak of the crisis and mitigate the negative effects upon its outbreak. Regardless of the type and duration of the crisis events, tourism has so far shown remarkable resilience.

    Full Text Available INTRODUÇÃO: A acatisia induzida por antipsicóticos é um transtorno de movimento relacionado ao sistema motor e caracterizado por sensação subjetiva de inquietude interna, irritabilidade ou disforia que podem ser intensas. Associa-se à sensação física e objetiva de desassossego e a movimentos não discinéticos. Esse efeito adverso pode predispor à pobre adesão ao tratamento e, conseqüentemente, favorecer recaídas. Assim, a escolha do melhor tratamento contribui para o alívio do sofrimento dos pacientes e favorece o melhor prognóstico. OBJETIVOS: Avaliar a eficácia e a tolerabilidade dos betabloqueadores, benzodiazepínicos e anticolinérgicos, comparados ao placebo e entre si, no tratamento de acatisia induzida por antipsicóticos, independente de idade ou diagnóstico psiquiátrico. MÉTODOS: Todos os estudos controlados, obtidos a partir das estratégias de busca que compararam betabloqueadores de ação central, benzodiazepínicos ou anticolinérgicos ao placebo e entre si, independente de sexo, idade ou diagnóstico psiquiátrico, foram considerados para esta atualização. Até março de 1999, foram consultadas sete bases de dados eletrônicos, sendo também examinadas as referências bibliográficas dos artigos selecionados. RESULTADOS: São apresentados 22 estudos controlados, sendo 13 comparando betabloqueadores, benzodiazepínicos e anticolinérgicos ao placebo e nove comparando diretamente as intervenções entre si. CONCLUSÕES: As três intervenções farmacológicas demonstraram eficácia superior comparadas ao placebo. Betabloqueadores de ação central mostraram-se mais eficazes, quando comparados a betabloqueadores de ação periférica, benzodiazepínicos e anticolinérgicos.INTRODUCTION: Neuroleptic-induced akathisia is a movement disorder related to the motor system characterized by complaints of inner restlessness, mental uneasiness, or dysphoria, all of which can be intense.

A membrana amniótica humana (MA devido às suas propriedades anti-inflamatórias e anti-fibróticas pode ser uma terapia alternativa. A proposta desse trabalho é analisar as alterações nos níveis séricos das principais enzimas celulares e da albumina, na fibrose hepática induzida pela ligadura do ducto biliar (LDB e após o tratamento com a MA. Dez ratos foram divididos nos grupos LDB e LDB+MA, e eutanasiados após 9 semanas da LDB. As amostras de sangue foram processadas bioquimicamente para análise da albumina (ALB, fosfatase alcalina (FA e transaminases (TGP e TGO.  Comparando os grupos experimentais verificou-se que no grupo LDB+MA houve a diminuição da ALB e TGP e no grupo LDB houve a diminuição da FA e TGO, entretanto sem apresentar diferença significante entre os grupos. Conclui-se que a MA, quando aplicada ao fígado no mesmo momento da indução da fibrose, parece não ter exercido efeito significativo na função hepática.

    Prolonged economic downturns and economic crises are affecting nations around the world, including developed countries such as Portugal, Spain, and Greece. In the United States, recovery from the latest economic crisis has been accompanied by a persistently high rate of unemployment. To a large extent, the impacts on the nursing profession may depend on the severity of economic downturns and their duration in the country of employment of nurses. Nurses in certain areas of patient care (such as mental health) may also be more strongly affected because of the impact of economic crises and high unemployment on morbidity patterns. Emigration of nurses may also increase as a result of prolonged economic crisis.

    Background The up-regulation of P-selectin in endothelial cells and platelets contributes to the cell-cell interactions that are involved in the pathogenesis of vaso-occlusion and sickle cell-related pain crises. The safety and efficacy of crizanlizumab, an antibody against the adhesion molecule P-selectin, were evaluated in patients with sickle cell disease. Methods In this double-blind, randomized, placebo-controlled, phase 2 trial, we assigned patients to receive low-dose crizanlizumab (2.5 mg per kilogram of body weight), high-dose crizanlizumab (5.0 mg per kilogram), or placebo, administered intravenously 14 times over a period of 52 weeks. Patients who were receiving concomitant hydroxyurea as well as those not receiving hydroxyurea were included in the study. The primary end point was the annual rate of sickle cell-related pain crises with high-dose crizanlizumab versus placebo. The annual rate of days hospitalized, the times to first and second crises, annual rates of uncomplicated crises (defined as crises other than the acute chest syndrome, hepatic sequestration, splenic sequestration, or priapism) and the acute chest syndrome, and patient-reported outcomes were also assessed. Results A total of 198 patients underwent randomization at 60 sites. The median rate of crises per year was 1.63 with high-dose crizanlizumab versus 2.98 with placebo (indicating a 45.3% lower rate with high-dose crizanlizumab, P=0.01). The median time to the first crisis was significantly longer with high-dose crizanlizumab than with placebo (4.07 vs. 1.38 months, P=0.001), as was the median time to the second crisis (10.32 vs. 5.09 months, P=0.02). The median rate of uncomplicated crises per year was 1.08 with high-dose crizanlizumab, as compared with 2.91 with placebo (indicating a 62.9% lower rate with high-dose crizanlizumab, P=0.02). Adverse events that occurred in 10% or more of the patients in either active-treatment group and at a frequency that was at least twice as high

    2002-12-01

    Between 1114 and 1170 Syria was struck by 7 seismic crises: 5 were great earthquakes (August and November 1114, November 1115, June 1117, June 1170), amongst which that of 29th June 1170 represents one of the most destructive events of the Middle-Eastern and Mediterranean area. Instead 2 were long and violent tremor sequences without a real main shock: the first one went on from October 1138 to June 1139, the second from September 1156 to May 1159. Until now all of these seismic events had been known mostly through Arab sources. However, owing to the particular political and military situation in the Syria of that period, such sources could not provide a complete frame of reference. Indeed, in those years in the territories of Syria and present-day Lebanon, some Latin States had been formed due to the military invasion of the Frankish Crusades. Furthermore, Syria was a privileged territory of travellers from various countries heading towards Palestine. Hence, basing ourselves on complex and diversified types of sources, precious new data have emerged written in Latin, Frankish, Greek, Armenian and Syrian. At the same time, the contribution of the Arab sources has been broadened. The overall picture that has emerged offers a new observational basis that has allowed us to date, differentiate, localise and thoroughly evaluate the elements of at least 5 of these earthquakes (the best documented ones: November 1114, 1115, 1138-39, 1156-59 and 1170). Overall nearly 90 hit locations have been identified, about 30 of which new and unknown to the previous studies. It has thus been possible for the first time to shed light on the intense seismic activity that affected this region in the dark ages. In just less than 60 years all of the vast territory that includes present-day Lebanon, north-eastern Syria and south-eastern Turkey was repeatedly struck. The earthquakes of 13th November 1114 and 29th November 1115 (until today often muddled up), and the sequence in 1138-39 hit

    Full Text Available The basic lessons obtained from financial turbulences all over the wor ld are the need to spot main causes, identify the triggering risk factors and consequently develop resolution plans for the potential financial crises, which include the establishment of a sound and strong financial system with strengthened institutional and structural bodies. Accurately and timely detection of the main causes that trigger financial fragilitiesemerging from currency, debt and banking is supposed to guide regulators to find "to the point" solutions to the fragility problems and to isolate their effects. Since in the Turkey case, financial crises were observed to occur in the form of twin crises or triplet crises, in this paper, we put forward Turkey-specific diagnoses and suggestions. Thus, the main factors that triggered financial turmoils in Turkey's last quarter century are low GDP, inadequate equity capital, insufficient bank returns, poor FX reserve, high inflation, short position-hot money policy, capital outflows, manipulative credit ratings and bank inertia, namely a trade off betweencredit transactions and risk-free investment vehicles

    Full Text Available Resumo: Crises de marca, decorrentes de falhas no produto, têm se tornado mais frequentes em razão do aumento da complexidade dos produtos. As crises geradas por campanhas de recall são únicas, inesperadas e podem gerar deterioração da relação favorável estabelecida entre a marca e o consumidor, afetar a imagem de marca e reduzir o brand equity. Suas consequências envolvem prejuízos financeiros de curto e longo prazo para a marca, para a empresa e, eventualmente, para a categoria como um todo. Este artigo é fruto de uma pesquisa exploratória qualitativa realizada por meio de um estudo de caso único na indústria de alimentos. Seu objetivo é verificar empiricamente a aplicação das teorias sobre crise de marca e recall em um caso brasileiro recente. Os resultados encontrados estão alinhados com as suposições elaboradas com base no referencial teórico. Como contribuição adicional para o tema, o estudo apresenta o efeito de uma crise real ao longo do tempo.

    Full Text Available One of the sociological features of the current economic crises had been its beginning as a media fact rather than economic reality for ordinary people in Poland. Until the very end of 2008 the offi cial strategy of Polish government was denying of present of any economic crises in Poland: “The Polish economy as well as Polish banking system are used to be healthy and in good conditions and we will be suffer a little slow done because we are not an island”. Unfortunately it occurs not to be true.Based on discourse analysis of two major Polish daily and two weekly we would like to show the evolution of narrative describing crises in global terms and particularly at the domestic market. What was the picture of global crises at the beginning of this discussion, how it supposed to affect Poland, who serve as experts and opinion givers and finally how through the language we can observe the change from ‘slow down’ to ‘crises’? This are basic questions we would like to answer in our text.

    2012-04-01

    Full Text Available L’Union européenne est durement affectée par la crise des dettes souveraines. Cette crise peut être interprétée comme la conséquence de plusieurs faits importants : une absence de leadership européen, des inégalités fortes parfois anciennes entre les performances macroéconomiques des pays membres, des faiblesses structurelles déjà observables avant la crise dans certains pays. Mais le principal facteur de fragilité de l’Union européenne réside dans sa division interne. Tant que la problématique de l’intégration européenne ne sera pas appropriée par les citoyens européens eux-mêmes et tant que certaines politiques ne seront pas davantage coordonnées, l’Union restera sur le fil du rasoir. Cette crise met en lumière l’essoufflement d’un certain modèle d’intégration. Dans cet article, on explore ces problématiques avec un regard géographique.

    2012-04-01

    Full Text Available Este artigo discute a crise ambiental por meio de um diálogo entre a psicanálise, filosofia e ciências sociais. Busca-se introduzir um eixo comum de compreensão das relações entre a psiquê e a natureza, a partir de um texto reflexivo sobre a natureza humana, sua complexidade e suas sociopatias. A crise socioambiental em que vivemos é tratada a partir das seguintes proposições: (i a humanidade se distanciou da sua condição natural; (ii a humanidade pode estar psicologicamente doente; (iii a humanidade não está moralmente apta para delegar a superação da crise às futuras gerações, pois vivemos num simulacro que envolve consumismo e alienação. Conclui-se que há uma dimensão subjetiva na raiz da crise ambiental, de cuja análise depende a solução real do impasse civilizacional com o qual nos defrontamos.

  7. Bond markets and banking crises in emerging market economies: The role of institutions

    Directory of Open Access Journals (Sweden)

    Boukhatem Jamel

    2012-01-01

    Full Text Available This paper deals with the question of knowing if countries whose activity of financing is mainly bank based face crises more expensive than those where the bond markets are broader and more developed. The results of the empirical tests on a panel of emerging countries suggest that bank based financial systems are associated with crises slightly more expensive, whereas the relationship between the bond markets and the crises’ costs is fragile. Moreover, financial systems where bond markets play an important role are associated with a higher growth of the production, and this, independently of the presence or not of crises. The consideration of the combined effect of financial liberalization and institutional framework on the bond markets development shows the importance of the direction of the financial liberalization. We join in this case one of the most significant aspects of the “sequencing” theorized by McKinnon (1973. Finally, an effective prudential regulation tends to reduce significantly the probability of occurrence of banking crises.

  14. Vulnerability of countries to food-production crises propagating in the virtual water trade network

    Science.gov (United States)

    Tamea, S.; Laio, F.; Ridolfi, L.

    2015-12-01

    In recent years, the international trade of food and agricultural commodities has undergone a marked increase of exchanged volumes and an expansion of the trade network. This globalization of trade has both positive and negative effects, but the interconnectedness and external dependency of countries generate complex dynamics which are often difficult to understand and model. In this study we consider the volume of water used for the production of agricultural commodities, virtually exchanged among countries through commodity trade, i.e. the virtual water trade. Then, we set up a parsimonious mechanistic model describing the propagation, into the global trade network, of food-production crises generated locally by a social, economic or environmental event (such as war, economic crisis, drought, pest). The model, accounting for the network structure and the virtual water balance of all countries, bases on rules derived from observed virtual water flows and on data-based and statistically verified assumption. It is also tested on real case studies that prove its capability to capture the main features of crises propagation. The model is then employed as the basis for the development of an index of country vulnerability, measuring the exposure of countries to crises propagating in the virtual water trade network. Results of the analysis are discussed within the context of socio-economic and environmental conditions of countries, showing that not only water-scarce, but also wealthy and globalized countries, are among the most vulnerable to external crises. The temporal analysis for the period 1986-2011 reveals that the global average vulnerability has strongly increased over time, confirming the increased exposure of countries to external crises which may occur in the virtual water trade network.

  15. Alterações fetais induzidas pelo uso de antiinflamatórios durante a gestação

    Directory of Open Access Journals (Sweden)

    Fonseca Cláudia Sampaio

    2002-01-01

    Full Text Available Em geral, todos os efeitos dos antiinflamatórios estão relacionados com a inibição da ciclo-oxigenase (COX do ácido araquidônico e, portanto, inibição da produção de prostaglandinas e tromboxanos. Existem dois tipos de COX, quais sejam COX-1 e COX-2. A COX-1 é uma enzima constitucional expressa em muitos tecidos, incluindo plaquetas sangüíneas, e está envolvida na homeostase tecidual. Por outro lado, a COX-2 é induzida em células inflamatórias quando elas são ativadas, sendo considerada a enzima que produz os mediadores da inflamação da classe dos prostanóides. A ação dos antiinflamatórios está relacionada à inibição da COX-2 e é provável que seus efeitos indesejados se devam principalmente à inibição da COX-1. Tratamentos maternos com antiinflamatórios não esteroidais (AINEs têm sido associados, com freqüência, à vasoconstrição do ducto arterioso fetal, hipertensão arterial pulmonar e inibição da agregação plaquetária. Alterações na hemostasia são alguns dos efeitos colaterais produzidos pelo uso incontrolado dos AINEs, os quais induzem a um desequilíbrio na liberação de prostaglandinas e tromboxanos, que se reflete na adesividade e agregação plaquetária. As alterações hemostáticas observadas em neonatos, decorrentes do uso de salicilatos pela mãe, ocorrem devido à inibição da agregação plaquetária e à diminuição da atividade do fator XII relacionado à coagulação sangüínea. Estudos em camundongos revelaram que o uso de corticóides durante a gestação pode levar a anormalidades no desenvolvimento fetal, por alterações na diferenciação celular.

    2011-10-01

    Full Text Available Osteonecrose dos maxilares relacionada aos bisfosfonatos pode ser uma complicação importante do tratamento da osteoporose a longo prazo. A possibilidade de osteonecrose dos maxilares em pacientes expostos a bisfosfonatos nitrogenados foi descrita pela primeira vez em 2003. Desde então, relatos de casos e estudos retrospectivos demonstraram maiores percentuais de ocorrência de osteonecrose em pacientes que fizeram ou fazem uso de bisfosfonatos. Embora esta complicação possa ser espontânea, os procedimentos invasivos orais têm um papel como fatores de risco associados aos procedimentos odontológicos, tais como as extrações dentárias e cirurgias de outros ossos. Além disso, infecções dentárias e doença periodontal são relatadas como principais fatores de risco para o desenvolvimento de osteonecrose dos maxilares induzida por bisfosfonatos. Por isso, dentistas, clínicos gerais, ortopedistas, geriatras e cirurgiões bucomaxilofaciais precisam estar cientes do problema e trabalhar em um ambiente multidisciplinar, incentivando o diagnóstico precoce e a prevenção de novos casos potenciais.Bisphosphonate-related osteonecrosis of the maxillae may be an important complication of long-term osteoporosis treatment. The possibility of osteonecrosis of the maxillae in patients exposed to nitrogenated bisphosphonates was first described in 2003. Since then, case reports and retrospective studies have demonstrated higher percentages of occurrence of osteonecrosis in patients who have used or are using bisphosphonates. Although this complication may be spontaneous, invasive oral procedures have a role as risk factors associated with dental procedures such as tooth extractions and other bone operations. In addition, tooth infections and periodontal disease have been reported to be the main risk factors for development of bisphosphonate-induced osteonecrosis of the maxillae. For this reason, dentists, general clinicians, orthopedists

  17. AVALIAÇÃO DE CITOCINAS NA FIBROSE HEPÁTICA INDUZIDA EM RATOS PELA LIGADURA DO DUCTO BILIAR

    Directory of Open Access Journals (Sweden)

    Juliana Saraiva Freitas

    2015-01-01

    Full Text Available A fibrose hepática é uma doença causada por uma grande variedade de doenças crônicas que afetam o fígado após diferentes agressões, cujo único tratamento é o transplante de fígado. A patogênese da fibrose engloba uma complexa interação entre as células e a matriz extracelular do tecido hepático, interações estas mediadas por citocinas que modulam a progressão da fibrose. O objetivo do trabalho foi analisar quantitativamente o perfil de citocinas pró-inflamatórias (IL-6 e TNF-a e anti-inflamatória (IL-10 no fígado de ratos, com diferentes graus de fibrose, induzida pela ligadura do ducto biliar (LDB. Vinte ratos foram submetidos ao procedimento da LDB e eutanasiados após 2, 4 e 6 semanas da indução da fibrose para a remoção do fígado e quantificação das citocinas pró e anti-inflamatórias pelo método de ELISA sanduíche. Foi observado o aumento na concentração de todas as citocinas após 4 semanas da LDB e diminuição dessas concentrações na 6ª semana. Dentre as citocinas pró-inflamatórias, o TNF-a mostrou aumento e diminuição estatisticamente significantes, respectivamente, na 4ª e 6ª semana, quando comparado a IL-6, a qual não apresentou significância estatística em nenhuma semana após a LDB. A IL-10, mostrou-se, significativamente, elevada na 4ª semana, seguida de uma diminuição moderada na 6ª semana. Esses resultados indicam que o TNF é a principal citocina na progessão da fibrose biliar, principalmente, durante sua fase intermediária. Ao mesmo tempo, a IL-10 atua nessa fase, limitando a produção da citocina pró-inflamatória TNF-a, na tentativa de um controle endógeno da progressão da doença.

    Full Text Available Os anticoagulantes orais que atuam através do antagonismo à vitamina K são utilizados na prática clínica há muito tempo, porém ainda há dificuldades no seu manejo e na condução das complicações. Entre as complicações, as mais conhecidas são os transtornos hemorrágicos, mas outras também devem ser reconhecidas, tais como a necrose induzida por varfarina. Esta é uma grave, porém rara complicação, cuja fisiopatologia é ainda obscura e cujas causas são indefinidas. Dentre as possíveis causas, as mais prováveis são a deficiência de proteína C e de proteína S, reações de hipersensibilidade e deficiência de fator VII. Há maior incidência desta complicação entre mulheres de meia-idade, acometendo preferencialmente mamas e glúteos. As medidas mais importantes para o tratamento são: suspensão imediata da droga, uso de heparina não fracionada ou de baixo peso molecular em doses terapêuticas, emprego da vitamina K e, eventualmente, infusão de plasma fresco congelado ou de proteína C ativada recombinante.Oral anticoagulants acting via vitamin K antagonists have long been employed in the clinical practice. However, difficulties related to the management of treatment regimens and complications still persist. Among the complications, bleeding disorders are widely known, but others should also be taken into consideration, such as warfarin-induced skin necrosis. The pathophysiology of this rare but severe complication is still obscure, and its causes remain to be defined. Among possible causes, protein C and protein S deficiency, hypersensitivity reactions and VII factor deficiency are the most probable ones. There is an increased incidence of warfarin-induced skin necrosis among middle-aged women, usually affecting breasts and buttocks. The most important treatment measures are immediate discontinuation of the drug, use of unfractionated or low-molecular-weight heparin at therapeutic doses, use of vitamin K and

    2016-09-01

    Bone crises in type 1 Gaucher disease are reported in long bones and occasionally in weight bearing bones and other bones, but rarely in small bones of the hands and feet. We retrospectively examined the incidence of bone pain in patients followed at the Rabin Medical Center, Israel, before and following the initiation of enzyme replacement therapy (ERT) and evaluated them for bone crises. Of 100 type I Gaucher disease patients, 30 (30%) experienced one or more bone crises. Small bone crises represented 31.5% of all bone crises and were always preceded by crises in other bones. While the incidence of long bone crises reduced after the initiation of ERT, small bone crises increased. Almost 60% of patients with bone crises were of the N370S/84GG genotype suggesting a greater susceptibility of N370S/84GG patients to severe bone complications. These patients also underwent the greatest number of splenectomies (70.6% of splenectomised patients). Splenectomised patients showed a trend towards increased long and small bone crises after surgery. Active investigation of acute pain in the hands and feet in patients in our cohort has revealed a high incidence of small bone crises. Physicians should consider imaging studies to investigate unexplained pain in these areas.

    Sickle cell disease is one of the most common genetic disorders. Sickle cell crises in which irregular and dehydrated cells contribute to blocking of blood vessels are characterised by episodes of pain. Treatment is mainly supportive and symptomatic. In vitro studies with piracetam indicate that it has the potential for inhibition and a reversal of the process of sickling of erythrocytes. This is an update of a previously published Cochrane review. To assess the effectiveness of piracetam for reducing the incidence of painful sickle cell disease crises. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Last search of the Group's Haemoglobinopathies Trials Register: 21 September 2015. Randomised controlled trials comparing orally administered piracetam to placebo or standard care in people, of all ages and both sexes, with sickle cell disease. Two authors independently assessed trial quality and extracted data. Trial authors were contacted for additional information. Adverse effects data were collected from the trials. Three trials involving 169 participants were included in the review. A limited amount of data addressing some of the primary and some of the secondary outcomes were provided, but data were incomplete and based on un-validated assumptions used in the evaluation of outcomes. One trial reported a reduction in the number of pain crises and their severity with active intervention than placebo but presented no data to confirm these results. A second trial presented a monthly global pain score based on the number of sickle cell crises and severity of pain but included no separate data for these primary outcomes. Although there was no significant difference between the piracetam and placebo periods for the number of days of

Este artigo tem o objetivo de apresentar as conexões existentes entre essas duas crises e a conjuntura da economia-mundo capitalista das últimas décadas do século XIX, enfatizando o problema da dívida externa e da política econômica, e re-organizando algumas contribuições da historiografia econômica por meio da metodologia da "encompassing comparison" e da teoria dos ciclos mundiais de endividamento. O artigo mostra que ambas as crises estiveram condicionadas pela dinâmica da economia-mundo capitalista, especialmente pelos fluxos mundiais de capital, não sendo resultados exclusivos de políticas econômicas nacionais.The end of the 19th century was characterized by economic growth and instability in Brazil and Argentina. In this period, two important economic crises took place - the Baring Crisis (in Argentina and the Encilhamento Crisis (in Brazil. The aim of this paper is to present the connections between these two crises and the dynamics of the capitalist world-economy of the end of the 19th century, focusing on the problems of external debt and economic policy and re-organizing some contributions of economic historiography through the methodology of "encompassing comparison" and of the world debt cycles' theory. The paper concludes that both crises were influenced by the dynamics of the capitalist world-economy, especially by the international flows of capital, and that they were not exclusive results of national economic policies.

  12. Contingency and Political Action: The Role of Leadership in Endogenously Created Crises

    Directory of Open Access Journals (Sweden)

    András Körösényi

    2016-06-01

    Full Text Available Among the recent literature about leadership and crisis situations two main strands are to be observed: structuralist ones mainly treat political leaders as reactive agents who have relatively little room for maneuver, while constructivist ones put greater emphasis on the opportunities in interpreting crises. Our claim is that there is a third analytical possibility mainly neglected in recent literature that is even more voluntaristic than the constructivist approaches. In this scenario, there is no external shock; leaders do not only interpret, but also “invent” crises. To make our claim plausible, we build a conceptual-descriptive typology of the potential relationships between crisis situations and agency. The typology is founded on Kari Palonen’s differentiation between Machiavellian and Weberian types of contingency, but uses his originally conceptual historical argument for analytical purposes. To underpin our theoretical argument, we present short illustrative examples to all three types of crisis scenarios (the structuralist, the constructivist, and the voluntarist one.

    We examined the time series properties of the foreign exchange market for 1990-2008 in relation to the history of the currency crises using the minimum spanning tree (MST) approach and made several meaningful observations about the MST of currencies. First, around currency crises, the mean correlation coefficient between currencies decreased whereas the normalized tree length increased. The mean correlation coefficient dropped dramatically passing through the Asian crisis and remained at the lowered level after that. Second, the Euro and the US dollar showed a strong negative correlation after 1997, implying that the prices of the two currencies moved in opposite directions. Third, we observed that Asian countries and Latin American countries moved away from the cluster center (USA) passing through the Asian crisis and Argentine crisis, respectively.

    Directory of Open Access Journals (Sweden)

    Luiz Carlos Bresser-Pereira

    2008-12-01

    Full Text Available Contrary to what conventional economic analysis afirms, the main cause of the financial crises in emerging countries during the 1990s, beginning with Mexico (1994 and ending with the crisis in Argentina (2001 was not primarily fiscal, but the decision by governments to foster growth with foreign savings, i.e., with current account deficits. Since the exchange rate has other determinants besides domestic absorption, the assumption of twin deficits often does not hold. These were balance of payment crises triggered by an overvalued local currency and the high increases in the foreign debt and/or the fast growth of the current account deficit. This led, foreign creditors to suddenly become persuaded that the country faced both liquidity and solvency problems, and to stop rolling over the debt. An econometric test substantiates these claims.

  18. Morality, energy, and the environment. [Causal interrelation of energy and social crises

    Energy Technology Data Exchange (ETDEWEB)

    Sayre, K.

    Our crises of energy and of social values are causally interrelated. Our energy problems have contributed substantially to our contemporary value problems, as evident, for example, by the institution of the private automobiles, which has begun to erode the very values it initially served. That our energy crisis has resulted from problems of value is illustrated by setting up a simple model of producer-consumer interaction, with egoism and hedonism as dominant principles of duty and of good, respectively, and by showing that an energy crisis like the one we are currently experiencing is practically inevitable. These discussions lead to an assessment of the possible roles moral philosophy might play in confronting these two crises by replacing energy hedonism with a low-energy life style.

    Moisés de Andrade Resende Filho

    Full Text Available Resumo: Investiga-se se crises de segurança do alimento deslocam para baixo as demandas por carne bovina, suína e de frango no Brasil. Constroem-se três séries de índices de crises de segurança do alimento, um para cada tipo de carne, somando-se o total de notícias na Folha de São Paulo que atenderam a critérios predefinidos de busca. Utilizam-se estas três séries, os preços das carnes e de um bem composto e o gasto per capita com consumo como variáveis explicativas em seis especificações alternativas de um sistema de quatro equações de demanda. Seleciona-se a melhor especificação do modelo por meio de testes ajustados de razão de verossimilhança. Testes com o modelo selecionado não rejeitam a hipótese de que as demandas não são afetadas por crises de segurança do alimento. Conclui-se que se deslocamentos da demanda para baixo em reação a crises de segurança do alimento criam incentivos para que as empresas adotem medidas para produzir um alimento mais seguro, tais incentivos não existem nos setores de carnes no Brasil. Assim, reforça-se a importância e necessidade de um sistema público ativo para regulamentar e estabelecer padrões de segurança da carne no Brasil.

    Directory of Open Access Journals (Sweden)

    Olszewska Barbara

    2014-06-01

    Full Text Available Crises in company development are a particular subset of management crises. They emerge on various stages of company development, as a result of gradual depletion of effective management solutions. Crisis situations in companies have varied impact on company stakeholders. The paper presents results of empirical studies of factors influencing company relations with market stakeholders and those that facilitate the process of restoring and maintaining any relations that suffered in the course of crises in company development. The authors’ intention was to identify such factors and evaluate their importance, in relation to various stages of company development and the associated types of crisis situations faced by companies. Empirical studies suggest that certain factors may facilitate conflict resolution in matters concerning company relations with market stakeholders, and that the impact of these factors varies depending on the phase of organizational development and the type of the associated crisis situation. It must be noted, that one of the most important factors to influence problem resolution is the perceived honesty of the exchange participants. Moreover, research suggests that opinions on the significance of organizational dependence of exchange participants in the resolution of problems in relations with market stakeholders are varied.

Alguns exemplos recentes parecem comprovar tal crise: o complexo de indústrias mundiais de alimentos que arrasa sementes tradicionais acabou por criar uma situação de desequilíbrio alimentar no planeta. Além disso, fatos como  a comercialização mundial do petróleo, o monopólio da comunicação e a realidade virtual manipulável demonstram que a internalização do Poder Público da modernidade provavelmente cederá espaço à transnacionalização desse mesmo Poder Público.

  14. Subsequent biotic crises delayed marine recovery following the late Permian mass extinction event in northern Italy.

    2017-01-01

    The late Permian mass extinction event was the largest biotic crisis of the Phanerozoic and has the longest recovery interval of any extinction event. It has been hypothesised that subsequent carbon isotope perturbations during the Early Triassic are associated with biotic crises that impeded benthic recovery. We test this hypothesis by undertaking the highest-resolution study yet made of the rock and fossil records of the entire Werfen Formation, Italy. Here, we show that elevated extinction rates were recorded not only in the Dienerian, as previously recognised, but also around the Smithian/Spathian boundary. Functional richness increases across the Smithian/Spathian boundary associated with elevated origination rates in the lower Spathian. The taxonomic and functional composition of benthic faunas only recorded two significant changes: (1) reduced heterogeneity in the Dienerian, and (2) and a faunal turnover across the Smithian/Spathian boundary. The elevated extinctions and compositional shifts in the Dienerian and across the Smithian/Spathian boundary are associated with a negative and positive isotope excursion, respectively, which supports the hypothesis that subsequent biotic crises are associated with carbon isotope shifts. The Spathian fauna represents a more advanced ecological state, not recognised in the previous members of the Werfen Formation, with increased habitat differentiation, a shift in the dominant modes of life, appearance of stenohaline taxa and the occupation of the erect and infaunal tiers. In addition to subsequent biotic crises delaying the recovery, therefore, persistent environmental stress limited the ecological complexity of benthic recovery prior to the Spathian.

A problematização dessa tese pressupõe considerar a perda de critérios para avaliar a crise na educação e ao mesmo tempo voltar à questão mesma, à essência da educação. Feito isso, sugerimos que o amor mundi no pensamento arendtiano é o princípio que articula responsabilidade e ação por parte daqueles que elegeram a docência como forma de inserção e atividade no mundo.Como princípio de ação pode inspirar uma nova prática ético-política no campo educativo.   Palavras-chave: educação; pensamento; amor mundi; responsabilidade; Hannah Arendt.

O presente texto procura discutir também esta alternativa, considerando que os processos sociais da modernidade se autonomizam dos seus agentes e constituem como que um "sujeito automático" a subjugar os sujeitos conscientes e envolvê-los em suas estruturas. O sujeito relativamente consciente e livre só pontua através da crise em que entram aqueles processos sociais, como verificamos na atualidade. A crise representa, assim, o ressurgimento da história enquanto oportunidade decisiva para reordenar, mediante a crítica, a trama da identidade e da diferença, constitutiva tanto da existência social quanto da consciência historiadora.

    An analysis of the response of American markets to supply crises in world oil markets is presented. It addresses four main issues: the efficiency of the operation of American oil markets during oil supply crises; the problems of both economic efficiency and social equity which arise during the American adaptation process; the propriety of the Federal government's past policy responses to these problems; and the relationship between perceptions of the problems caused by world oil crises and the real economic natures of these problems. Specifically, Chapter 1 presents a theoretical discussion of the effects of a world supply disruption on the price level and supply availability of the world market oil to any consuming country including the US Chapter 2 provides a theoretical and empirical analysis of the efficiency of the adaptations of US oil product markets to higher world oil prices. Chapter 3 examines the responses of various groups of US oil firms to the alterations observed in world markets, while Chapter 4 presents a theoretical explanation for the price-lagging behavior exhibited by firms in the US oil industry. Chapter 5 addresses the nature of both real and imagined oil market problems in the US during periods of world oil market transition. (MCW)

    Full Text Available In this case study, I examine the quality of decision-making under conditions of rapidly evolving urban water crises, and the adaptive policy challenges of building regional resilience in response to both drought and flood. Like other regions of Australia, Southeast Queensland has been subject to substantial cycles of drought and flood. I draw on resilience literature concerning sustainability, together with governance literature on policy change, to explain the changing awareness of urban water crises and the strategic options available for addressing these crises in this case study. The problem of resilience thinking opens up a number of important questions about the efficacy and adaptability of the policy system. The case provides insights into the interplay between the ways in which problems are framed, the knowledge bases required for planning and decision-making, the collaborative governance processes required for managing complex and rapidly evolving issues, and the overall capacity for policy learning over time. Regional resilience was proclaimed as a policy goal by government, but the practices remained largely anchored in traditional technical frameworks. Centralized investment decisions and governance restructures provoked conflict between levels of government, undermining the capacity of stakeholders to create more consensual approaches to problem-solving and limiting the collective learning that could have emerged.

  20. Early Cretaceous CO2 Pulses: Trigger of Carbon Cycle Perturbations and of Biocalcification Crises

    The Early Cretaceous C-isotope curve is marked by several positive carbon isotope anomalies with an amplitude of 2-3 ppm and lasting up to millions of years. The two most prominent of these excursions are of Late Valanginian and Aptian age. Isotopic mass balance models suggest that positive carbon isotope excursions reflect altered partitioning of carbon between the oxidized and reduced carbon sinks and that these changes occurred in response to elevated atmospheric CO_2 levels and coupled climate change. Both carbon isotope anomalies coincide with episodes of increased volcanic activity, which is regarded as the source of excess atmospheric carbon dioxide. The Aptian carbon isotope anomaly is preceded by a short-lived negative carbon isotope pulse of up to 2 ppm amplitude while a comparable pulse is not recognized at the base of the Valanginian carbon isotope excursion. This C- isotope event may record a climate-induced destabilisation of sedimentary gas hydrates and the sudden release of methane to oceans and atmosphere. Both, the Aptian and the Valanginian carbon isotope excursions are accompanied by biocalcification crises on carbonate platforms and in pelagic environments. The Valanginian carbonate platform drowning, the nannoconid crisis and the disappearance of calpionellids coincide with the beginning of the positive carbon isotope anomaly. The Aptian biocalcification crises on platforms and in pelagic environments started before the negative carbon isotope spike. Both crises in biocalcification may have been triggered by p CO_2-induced changes in surface water chemistry and/or by sudden changes in temperatures and/or by changes in nutrient levels. Available paleoclimate data and the bulk oxygen isotope records show no evidence for major low latitude ocean paleotemperature changes at the base of the Valanginian isotope anomaly. Partial choking of carbonate production during the Aptian occurred at a time of decreasing oxygen isotope values in pelagic bulk

    Full Text Available Antiepileptic drugs may cause worsening of epilepsy by aggravating pre-existing seizures or by triggering new seizure types. There are several reports of adverse effects related to midazolam, but only a few authors reported epileptic manifestations. We report four newborns seen at the Neonatal Intensive Care Unit of our University Hospital, who developed seizures a few seconds after the administration of midazolam. It is difficult to identify the patients at risk, but it is important to be aware and recognize this situation.Drogas antiepilépticas podem piorar o controle da epilepsia por agravar crises epilépticas pre-existentes ou por desencadear novos tipos de crises. Existem vários relatos de eventos adversos relacionados ao midazolam; entretanto, poucos autores referem manifestações epilépticas. Neste estudo relatamos a ocorrência de crises epilépticas poucos segundos após a administração de midazolam, em quatro neonatos atendidos na Unidade de Terapia Intensiva do nosso hospital universitário. É difícil determinar quais pacientes estão em risco, mas é importante estar atento e reconhecer esta situação.

    Full Text Available Para estabelecer um modelo experimental para o estudo da etiologia, patologia e patogênese da polioencefalomalacia (PEM em bovinos, a condição foi induzida em quatro novilhos pela administração oral de amprólio nas doses diárias de 500 e 350mg/kg de peso vivo, respectivamente por 22 e 26-28 dias. Todos os bovinos morreram espontaneamente ou foram eutanasiados in extremis após um curso clínico de 4-7 dias. Três bovinos que receberam 1.000mg/kg de amprólio e dois que receberam 500mg/kg morreram espontaneamente com quadro clínico agudo a subagudo sem desenvolverem sinais e lesões de PEM. Nos novilhos que PEM foi reproduzida, os sinais neurológicos incluíram marcada apatia, incoordenação, posição de cavalete, quedas ocasionais, hiperexcitabilidade, tremores musculares, cegueira, bruxismo, estrabismo, nistagmo, midríase, opistótono, decúbito lateral e movimentos de pedalagem. Os principais achados de necropsia eram restritos ao encéfalo e consistiam de tumefação, achatamento, amolecimento e amarelamento das circunvoluções cerebrais. Histologicamente, havia necrose neuronal segmentar e laminar (neurônios vermelhos associada a edema, tumefação endotelial, separação das lâminas de neurônios do córtex telencefálico ou entre as substâncias cinzenta e branca e infiltração moderada a acentuada de macrófagos espumosos. Essas alterações eram mais acentuadas nos lobos telencefálicos frontal, parietal e occipital. Adicionalmente, lesões similares e moderadas foram detectadas no mesencéfalo e hipocampo.

    Desde 2007, temos acompanhado as notícias sobre a mais profunda crise do
    capitalismo, segundo analistas de todos os matizes, desde a grande depressão de
    1929. A crise tem seu estopim no mercado financeiro, por meio do esgotamento
    do crédito, e no epicentro do sistema, a potência econômico-militar norteamericana.
    E se alastra obrigando muitos que dormiram neoliberais num dia a
    acordarem keynesianos no outro, reivindicando mais do que nunca o suporte do
    fundo público dos Estados nacionais. A crise abre uma onda de falências,
    concordatas, aquisições e fusões, num profundo processo de concentração de

    An economic crisis has been defined as a situation in which the scale of a country's economy becomes smaller in a period of time. Economic crises happen for various reasons, including economic sanctions. Economic crises in a country may affect national priorities for investment and expenditure and reduce available resources, and hence may affect the health care sector including access to medicines. We reviewed the pharmaceutical policies that the countries adopted in order to mitigate the potential negative effects on access to medicines. We reviewed published reports and articles after conducting a comprehensive search of the PubMed and the Google Scholar. After extracting relevant data from the identified articles, we used the World Health Organization (WHO) access to medicines framework as a guide for the categorization of the policies. We identified a total of 40 studies, of which 10 reported the national pharmaceutical policies adopted to reduce the negative impacts of economic crises on access to medicines in high-income and middle-income countries. We identified 89 policies adopted in the 11 countries and categorized them into 12 distinct policy directions. Most of the policies focused on financial aspects of the pharmaceutical sector. In some cases, countries adopted policies that potentially had negative effects on access to medicines. Only Italy had adopted policies encompassing all four accesses to medicine factors recommended by the WHO. While the countries have adopted many seemingly effective policies, little evidence exists on the effectiveness of these policies to improve access to medicines at a time of an economic crisis.

    Full Text Available Orientation: Crises that threaten an organisation’s continued existence cannot be seen in isolation when considering the perception of threats to individual job security. These threats often go hand in hand with employee panic.Research purpose: The aim of this study was to establish a model to assist organisations in managing employee emotionality and panic during times of crisis.Motivation for the study: Environmental crises threaten organisations’ existence, threatening employees’ livelihood and resulting in employee panic. Panic reduces employees’ contributions. Organisations that are successful harness employee contributions at all times.Research design, approach, and method: A modernist qualitative research methodology was adopted, which included a case study as research strategy, purposive sampling to select 12 research participants, semi-structured interviews for data gathering, focus groups for data verification, and the use of grounded theory for data analysis.Main findings: An organisation’s ability to manage employee panic depends on the relationship between the foundational elements of authentic leadership, crisis readiness, resilience practices, versatile and committed talent, strategic management, quality management, and coherence actions taken during the crisis, which include crisis leadership, ongoing visible communication, mindfulness, work flexibility, and decisions based on the greatest financial need and social support.Practical/managerial implications: The study provides a best-practice option for managing emotionality during crises for the case organisation and other organisations within the vehicle components and other manufacturing industries.Contribution/value-add: The Coherence Hexagons Model is presented as a tool to manage employee panic during crisis.Keywords: crisis management; employee emotionality; employee panic; authentic leadership; talent management

  9. Perturbation of Aptian and Valanginian Carbon Cycle and Marine Biocalcification Crises

    2005-12-01

    The mid-Cretaceous is known as a time of major perturbations of the global carbon cycle, which coincided with widespread biocalcification crises. Detailed Ccarbonate and Corganic carbon isotope records through the early Aptian show a prominent negative spike followed by a positive carbon isotope anomaly with amplitude of up to 3permil. Based on cyclostratigraphy, the negative C-isotope anomaly lasted up to a few hundred thousand years while the positive excursion had duration of up to millions of years. The negative spike coincides with low oxygen isotope values documented from the Pacific and Tethys Oceans. Tethyan carbon isotope data indicate that fractionation between marine organic matter and carbonate was largest during the time of most negative carbon isotope values. These data provide evidence that atmospheric carbon dioxide levels were highest during the time of the negative spike. The negative carbon isotope spike coincides with a major biocalcification crisis which is recorded in pelagic, neritic and coastal environments. New carbon and strontium isotope data from Aptian coastal successions in Portugal confirm that the most severe Aptian biocalcification crisis started before but culminated during negative carbon isotope anomaly. The widespread Aptian biocalcifcation crisis seems to have been triggered by elevated atmospheric CO2 values related to volcanic activity. Sudden methane release contributed to an amplification of greenhouse climate and it led to further weakening of marine calcification. Comparable calcification crises are recognized in the Valanginian. There, a negative carbon isotope anomaly recoding a methane pulse is not observed. Volcanic degassing alone seems to have triggered this calcification crisis. The positive carbon isotope excursions in the early Aptian and in the Valanginian following the biocalcification crises record the response of oceans and biota to greenhouse climate. Increased organic carbon burial and an accelerated

    The police are considered frontline professionals in managing individuals experiencing mental health crises. This study examines the extent to which these individuals are disconnected from mental health services, and whether the police response has an influence on re-establishing contact. Police records were searched for calls regarding individuals with acute mental health needs and police handling of these calls. Mental healthcare contact data were retrieved from a Psychiatric Case Register. The police were called upon for mental health crisis situations 492 times within the study year, involving 336 individuals (i.e. 1.7 per 1000 inhabitants per year). Half of these individuals (N=162) were disengaged from mental health services, lacking regular care contact in the year prior to the crisis (apart from contact for crisis intervention). In the month following the crisis, 21% of those who were previously disengaged from services had regular care contact, and this was more frequent (49%) if the police had contacted the mental health services during the crisis. The influence of police referral to the services was still present the following year. However, for the majority (58%) of disengaged individuals police did not contact the mental health services at the time of crisis. The police deal with a substantial number of individuals experiencing a mental health crisis, half of whom are out of contact with mental health services, and police play an important role in linking these individuals to services. Training police officers to recognise and handle mental health crises, and implementing practical models of cooperation between the police and mental health services in dealing with such crises may further improve police referral of individuals disengaged from mental health services.

    Full Text Available La crise financière et économique a durement frappé les pays en développement, même si l’onde de choc les a atteints avec un certain retard. Chaque nation a ses propres défis à relever. Plus un pays en développement est intégré dans l’économie mondiale, plus les effets ont été dévastateurs. Et le redressement constaté aujourd’hui se limite pour le moment à un nombre restreint de pays et de régions.C’est essentiellement par le biais des flux commerciaux et financiers que la crise s’était propagée, rejetant des millions de gens dans le dénuement. Les pays en développement n’ont, dans l’ensemble, pas les mêmes moyens que les nations industrialisées lorsqu’il s’agit de stimuler la conjoncture tout en protégeant leurs catégories sociales les plus vulnérables. Mais beaucoup ont entrepris des efforts considérables pour atténuer les répercussions de la crise. Certains pays en développement ont intensifié leur coopération réciproque et réclament avec insistance d’être associés plus étroitement à l’élaboration des règles de l’économie mondiale. Les pays industrialisés s’occupent avant tout de leurs propres problèmes, et manifestent peu d’enthousiasme à l’idée d’accroître leur aide. Ils se voient mis sous pression par les institutions internationales qui les exhortent à céder une part de leur prédominance aux pays émergents. On voit se poursuivre le processus de déplacement des centres de gravité politiques et économiques, déjà constaté avant la crise financière.

    Full Text Available Este trabalho analisou a relação entre o comportamento do mercado acionário brasileiro, representado pelo Ibovespa, e os fluxos de capitais estrangeiros direcionados para investimentos em carteira de ações, no período posterior à implantação do Plano Real. Ao longo desse período, foram observadas diversas crises financeiras no âmbito internacional que provocaram instabilidade e volatilidade nos fluxos de capitais estrangeiros. Este trabalho considera as influências sistemáticas dessas instabilidades sobre o Ibovespa, especialmente pela capitalização relativamente pequena do mercado brasileiro de ações. A hipótese de mercado eficiente supõe que os preços das ações, e com isso o Ibovespa, seguem um caminho aleatório e não devem estar sujeitos a influências sistemáticas de outros fatores. A hipótese geral do trabalho é que os fluxos de capitais estrangeiros direcionados para o mercado acionário brasileiro influenciam significativamente o Ibovespa. A hipótese especifica que crises internacionais e nacionais influenciam negativamente os fluxos de capitais estrangeiros nesse segmento e com isso o Ibovespa. A justificação para este trabalho é de que essas influências sistemáticas de crises sobre o Ibovespa são um fator sistemático que limita a hipótese de mercado acionário brasileiro eficiente. Foi realizada uma análise empírica com diferentes modelos mostrando que há evidências de influência sistemática dos fluxos de capital estrangeiro em carteira de ações sobre o Ibovespa. Esses achados limitam, de certa forma, a adequação da hipótese de mercado eficiente para o mercado brasileiro de ações. Essa influência sistemática dos fluxos de capital estrangeiro sobre o Ibovespa pode ser um fenômeno restrito no período analisado, refletindo a alta volatilidade dos fluxos de capitais estrangeiros por causa de crises externas e internas.

    Full Text Available The aim of this study was to evaluate the influence of ligature-induced periodontal disease in pregnant rats on their newborn's health parameters. Twenty-four female adult Wistar rats were divided into two groups: the control group (G1 and the group that was submitted to dental ligatures around second upper molars (G2. After the four week period of development of periodontitis, the female animals were mated with male adult Wistar rats. There were no differences in the body weight of females between the two groups during mating and pregnancy. No differences were observed among the groups in relation to the viable newborn index. However, there were differences in newborn birth weight, explained by the diverse size of the litters. In this study, ligature-induced periodontal disease did not promote changes during pregnancy that resulted in low birth weight in newborn Wistar rats.O objetivo do presente estudo foi avaliar a influência da periodontite induzida por ligadura em ratas prenhes sobre parâmetros de saúde geral de seus filhotes. Vinte e quatro ratas Wistar de idade adulta foram divididas em dois grupos: grupo controle (G1 e grupo experimental, que recebeu ligaduras ao redor dos segundos molares superiores (G2. Após o período de indução de periodontite (quatro semanas, as ratas foram colocadas para cruzamento com ratos Wistar machos, adultos. Não houve diferença no peso corporal das fêmeas durante os períodos de cruzamento e prenhez. Também não foram observadas diferenças entre os grupos quanto à taxa de recém-nascidos viáveis. No entanto, houve diferença quanto ao peso dos recém-nascidos, sendo tal diferença explicada pela variação no tamanho das ninhadas. No presente estudo, doença periodontal induzida por ligadura não promoveu mudanças durante a prenhez que resultassem em baixo peso ao nascer dos filhotes Wistar.

    Full Text Available As sucessivas crises financeiras dos países "emergentes", na segunda metade dos anos 90, despertaram o interesse dos economistas do mainstream, uma vez que os modelos de crises cambiais de primeira geração, desenvolvidos nos anos 80, revelaram-se insuficientes para a compreensão destes eventos. Nesse contexto, foram desenvolvidos novos modelos que incorporaram, como condicionantes destas crises, fatos estilizados, que têm caracterizado o sistema financeiro internacional contemporâneo, dentre os quais os ataques especulativos auto-realizáveis e o comportamento de manada dos investidores estrangeiros. Este artigo pretende apresentar as principais características desses novos modelos. Primeiramente, apresentam-se os modelos desenvolvidos após a crise mexicana, que seguiram a tradição dos modelos de segunda geração desenvolvidos após a crise do Sistema Monetário Europeu. Em seguida, são examinados os modelos que surgem após a crise asiática, denominados "modelos de terceira geração", nos quais a crise cambial está intrinsecamente associada a uma crise bancária. Seguem-se algumas considerações finais.In the 90s, the succession of financial crises in the so called "emergent countries", with characteristics that haven't been considered by the first-generation models of exchange crises developed in the 80s, was followed by the emergency of new models of exchange crisis. The purpose of this article is to present these models, which have introduced in their analytical framework new elements, how the self-fulfilling expectations and the volatility of the capital flows. Firstly, we analyze the models developed after the Mexican crise, which have followed the tradition of the second-generation models that emerged after the European monetary system crise. Secondly, we examine the models developed after the Asian crise, labeled "third generation models", in which the exchange crise is intrinsically linked with a banking crise. We end up

In order to fulfill the aim mentioned above, an empirical approach was adopted to examine and analyze the deficiencies that exist in the current plans used by both public and private sectors in Jordan to face the negative effects of natural crises that strike Petra. Finally, a proposed model will be presented to the sectors mentioned above with recommendations on how these deficiencies can be eliminated to provide better crises management in Petra.

  4. The role of motivation, responsibility, and integrative complexity in crisis escalation: comparative studies of war and peace crises.

    Winter, David G

    2007-05-01

    Drawing on D. G. Winter's (1993) comparison of 1914 and the Cuban Missile Crisis, the author identified 8 paired crises (1 escalating to war, 1 peacefully resolved). Documents (diplomatic messages, speeches, official media commentary) from each crisis were scored for power, affiliation, and achievement motivation; text measures of responsibility and activity inhibition; and integrative complexity. Aggregated effect-size results show that war crises had significantly higher levels of power motivation and responsibility, whereas peace crises showed trends toward higher integrative complexity and achievement motivation. Follow-up analyses suggested that these results are robust with respect to both sides in a crisis, type of material scored, and historical time. The power motive results extend previous findings, but the responsibility results suggest that responsibility plays a paradoxical role in war. Future research directions are sketched, and the role of psychological content analysis in monitoring the danger of war is discussed.

    2013-02-01

    In the provision of care to older clients, home support workers regularly confront, avert, and manage crises. Semistructured interviews were conducted to explore the nature, type, and management of crises from the perspective of home support workers (N = 118) of older persons in British Columbia, Canada. The delivery of home health care occurs within a context of unpredictability related to scheduling, time constraints, variability of client need, and changing work environments. These events are experienced by 91% of home support workers and range from a serious medical incident (e.g., fall, death) to an interpersonal dilemma (e.g., client refusal of service, argument between worker and family member). Home support workers use a variety of strategies to manage these incidents. The analysis of crises enables us to better understand how agency and care policies may be more responsive to circumstances that challenge care work in home health settings.

  6. Charisma, volatility and violence: assessing the role of crises of charismatic authority in precipitating incidents of millenarian violence

    Directory of Open Access Journals (Sweden)

    John Walliss

    2006-01-01

    Full Text Available In this article the author develops some of the points he has made elsewhere regarding the role of what may be termed ‘crises of charismatic authority’ in producing volatility or even violence within marginal apocalyptic religious groups. The last quarter of the twentieth century witnessed several incidents where such groups engaged in violent actions against themselves, others in the outside world, or typically both (among them the Peoples Temple in Guayana in 1978, Branch Davidians in Waco, Texas in 1994, Order of the Solar Temple in Switzerland, Quebec and France in 1997, Aum Shirinkyo, Japan in 1995, Movement for the Restoration of the Ten Commandments of God, Uganda in 2000. This notion of ‘crises of charismatic authority’ has in many ways become a central, recurring theme in the author's analysis of these incidents. While accepting that such crises were typically not sufficient in themselves to have precipitated each of the dramatic denouements the author has examined, he has come to the conclusion that they did play a major role in each; such crises played a much more significant role than that played by external opposition in almost all of the cases the author examined (the case of the Branch Davidians being perhaps the exception that proves the rule. In this article, the author discusses what he means by crises of charismatic authority (an important task in itself due to the diverse understandings of ‘charisma’ found within the literature and presents a comparative analysis of some of the ways in which these crises can occur.

  7. Role of Social Media and Networking in Volcanic Crises and Communication

    2016-12-01

    The growth of social media as a primary and often preferred news source has led to the rapid dissemination of information about volcanic eruptions and potential volcanic crises as they begin, evolve, and end. This information comes from a variety of sources: news organisations, emergency management personnel, individuals (both members of the public and official representatives), and volcano monitoring agencies. Once posted, this information is easily shared, increasing the reach to a much broader population than more traditional forms of media, such as radio and newspapers. The onset and popularity of social media as a vehicle for dissemination of eruption information points toward the need to systematically incorporate social media into the official channels that volcano observatories use to distribute activity statements, forecasts, and images. We explore two examples of projects that collect/disseminate information regarding volcanic crises and eruptive activity via social media sources; the Smithsonian/USGS Weekly Volcanic Activity Report (WVAR), which summarizes new and on-going volcanic activity globally and on a weekly basis, and Eruptions, a blog that discusses eruptions as well as other volcanic topics. Based on these experiences, recommendations are made to volcanic observatories in relation to the use of social media as a communication tool. These recommendations include: using social media as a two-way dialogue to communicate and receive information directly from the public and other sources; stating that the social media account is from an official source; and posting types of information that users want to see such as images, videos, and figures.

    2011-06-01

    Full Text Available The strategies for structural-systemic crisis management have generated, to a geographical level, a number of differences between EU countries. These cleavages are the result of differentialmacroeconomic policies. In this context, this article has the aim of achieving a comparative approach between countries of the south, west and east of the EU space. Also our approach is focused on observing the nature of macroeconomic policies and also on identifying a "pattern" associated with a common ideal -type of "rational choice" in the efficient and effective management of systemic crises. This article aims to identify areas of growth and economic stability of a particular model of public policy and political-economic ideology, to set up a mechanism for "economic engineering”. From the methodological point of view, this article uses a quantitativemethodology, derived from mathematical analysis, statistics and stochastic, in order to explain, understand and predict the possible evolution of the systemic crises in the EU countries. The interest lies in the possibility of giving a model of macroeconomic policy for the adjustment of inflationist imbalances, labor market and pricepolicy, and also in regulating the equation of production-consumption.

    Full Text Available Urban gardens have been observed to multiply in response to crises. However, the meaning and motivations behind the emergence of gardening movements varies greatly over space and time. In this paper we argue that bottom up urban gardening initiatives taking place in Southern European countries in form of land occupation and communalization represent forms of resistance that enhance social cohesion and collective action in times of need. Specifically, this research examines the role of urban gardens in (i building community resilience and (ii articulating forms of resistance and contestation to development pressure and commodified urban lifestyles. Our research is based on data collected among 27 urban gardening initiatives in Barcelona, Spain, including 13 self-governed community gardens and 14 public gardens. Data were collected from semi-structured interviews with gardeners and with staff from the Barcelona City Council. Our results show mechanisms through which urban gardens can contribute to build resilience by nurturing social and ecological diversity, generating and transmitting local ecological knowledge, and by creating opportunities for collective action and self-organization. We further examine collectively managed gardens as urban commons that emerge as a form of resistance to the privatization of public urban space, and that offer opportunities to experiment with new models of urban lifestyles. We show how gardening initiatives can be seen to represent an emerging form of urban green commons that provides a suitable ground to ‘sow’ resilience and contestation in times of crises and socio-ecological deterioration.

A partir da análise de editoriais dos três principais jornais da imprensa brasileira entre maio e dezembro de 2005, meses do escândalo do "mensalão", este artigo observa outra faceta: como a crise é constituída como "desvio" a ser corrigido pela punição ou exclusão de determinados atores e comportamentos, impedindo que se coloque em questão os fundamentos do regime político.Press is frequently accused of being "incendiary", nourishing political crisis in an irresponsible way, in search of better headlines.

  12. Confronting ecological futures: global environmental crises in contemporary survival quests for young adults

    Directory of Open Access Journals (Sweden)

    Yvonne Hammer

    2010-01-01

    Full Text Available This paper examines representations of societal concern in the futuristic ecological disaster fictions of three British authors: Julie Bertagna (Exodus; Zenith, Jan Mark (Riding Tycho; Voyager and Marcus Sedgwick Floodland. The depicted refugee journeys in these futuristic worlds speak into a growing global disquiet that surrounds current historic events. Environmental crises that ground the emergent world orders of depicted future societies set the scene in each coming of age frame: each survival quest embeds social and cultural issues recognisable to contemporary audiences in futuristic representations of changed world orders, limited resources, and isolated communities. Authors resist the mythic frame of a traditional quest journey − a call to journey, the engagement with growth through a road of trials and then celebrations in a return to home territory: their conclusions offer limited resolutions, the struggle to survive entrenched as a linear path. Because authors link depictions of the refugee subject with environmental degradation, apocalyptic scenarios that signify the devastating consequences of global environmental crises provide an ecocritical platform from which each author situates a discourse of protest. Interrogating contemporary political positions of ambiguity and denial their novels profile social justice issues experienced by refugee populations in contemporary society.

    Full Text Available Retrospective view of the Ivorian crises from 1993 to 2011. At the independence, Ivory Coast is led by Felix Houphouët Boigny with a system of single party, the PDCI-RDA. The country enjoys political stability which is about the "Ivorian miracle". The economic upturn that knows a halt in 1979 led to social unrest, which later lead the President to re-establish a multiparty system in 1990. Even relative, peace has been preserved. The death of the father of the nation at December 7 of the year 1993 marks the beginning of a turbulent period characterized among other things by the division of the "heirs" meeting within the PDCI-RDA, the coup of 1999 and the bursting of the socio-political military crisis in 2002. The 2010 elections considered like the end of the long crisis will cause over 3,000 deaths due to severe post-electoral crisis that followed. What can we read today of these successive crises? What are the main factors and actors that have characterized the last twenty years of crisis? How are they structured the country? Our approach is backward looking. It is to see through a systematic analysis of past and present how Ivory Coast reached the current situation in order to draw lessons for the future.

  14. Crises and Collective Socio-Economic Phenomena: Simple Models and Challenges

    Bouchaud, Jean-Philippe

    2013-05-01

    Financial and economic history is strewn with bubbles and crashes, booms and busts, crises and upheavals of all sorts. Understanding the origin of these events is arguably one of the most important problems in economic theory. In this paper, we review recent efforts to include heterogeneities and interactions in models of decision. We argue that the so-called Random Field Ising model ( rfim) provides a unifying framework to account for many collective socio-economic phenomena that lead to sudden ruptures and crises. We discuss different models that can capture potentially destabilizing self-referential feedback loops, induced either by herding, i.e. reference to peers, or trending, i.e. reference to the past, and that account for some of the phenomenology missing in the standard models. We discuss some empirically testable predictions of these models, for example robust signatures of rfim-like herding effects, or the logarithmic decay of spatial correlations of voting patterns. One of the most striking result, inspired by statistical physics methods, is that Adam Smith's invisible hand can fail badly at solving simple coordination problems. We also insist on the issue of time-scales, that can be extremely long in some cases, and prevent socially optimal equilibria from being reached. As a theoretical challenge, the study of so-called "detailed-balance" violating decision rules is needed to decide whether conclusions based on current models (that all assume detailed-balance) are indeed robust and generic.

We specify the macroeconomic indicators we follow and we identify the symptoms associated with the associated disorder, as it is described by the economic literature as indicators that use to predict some of the internal crisis (currency, banking, balance of payment, all crisis at once. We see the dynamics of this indicators and we compare them with the the dynamics of the best leading indicators for a crisis, that were able to predict a crisis nationally, regionally or globally. We choose 7 early warning indicators that provided in-time valid signals about a crises in Romania, and we define a composite indicator for showing the distress of the economy (as each indicator can give a particular signal of distress, while the composite indicator shows the imminence of the Romanian Financial Crises of 2008-2010.

    Directory of Open Access Journals (Sweden)

    Monika Poettinger

    2013-12-01

    Full Text Available During the nineteenth century in Continental Europe, merchant networks founded enterprises wherever comparative or absolute advantages related to naturalresources or workers’ capabilities, but also changing economic policies, made it profitable. Incessantly comparing the cost-effectiveness of investments, merchant networks enhanced the efficiency of the entire economic system, but also favoured innovation, introducing technological advancements when feasible and potentially remunerative. At the same time, though, economic crises, more and more dependent on manufacturing and less on agricultural cycles, became manifest and an object of theoretical debate. The paper analyzes how merchant networks envisioned economic crises, if at all, and how the economic decision processes of such organizational structures responded to them. It will be ascertained that, more than sectorial imbalances and insufficient demand, the crisis that merchants really feared was the end of credibility and thus of access to credit. Personal failure could dramatically reduce the level of trust, depriving the merchant system of its functioning principle. The chosen framework of analysis describes the actual economic decision process, on which the distribution of production depended, and itsrelation to economic cycles.

  17. Finite-time singularities in the dynamics of Mexican financial crises

    2004-01-01

    Historically, symptoms of Mexican financial crises have been strongly reflected in the dynamics of the Mexican peso to the dollar exchange currency market. Specifically, in the Mexican financial crises during 1990's, the peso suffered significant depreciation processes, which has important impacts in the macro- and micro-economical environment. In this paper, it is shown that the peso depreciation growth was greater than an exponential and that these growth rates are compatible with a spontaneous singularity occurring at a critical time, which signals an abrupt transition to new dynamical conditions. As in the major 1990's financial crisis in 1994-1995, some control actions (e.g., increasing the USA dollar supply) are commonly taken to decelerate the degree of abruptness of peso depreciation. Implications of these control actions on the crisis dynamics are discussed. Interestingly, by means of a simple model, it is demonstrated that the time at which the control actions begin to apply is critical to moderate the adverse effects of the financial crisis.

    Full Text Available Heparin-induced thrombocytopenia (HIT is a transient disorder caused by platelet-activating antibodies against platelet factor 4 (PF4-heparin complexes. Clinically it translates into arterial or venous thrombosis and carries high morbidity and mortality. The use of large doses of heparin during endovascular repair of abdominal aortic aneurysm could increase the incidence of HIT. We report two cases associating the use of heparin during endovascular repair of abdominal aortic aneurysm with the development of HIT.Trombocitopenia induzida por heparina (TIH é um distúrbio transitório causado pela ativação de anticorpos anti-plaquetários contra o fator plaquetário 4 (FP4 combinado com a molécula de heparina, formando complexos que clinicamente se traduzem em tromboses arteriais ou venosas com alta morbimortalidade. O uso de altas doses de heparina durante procedimentos endovasculares para o tratamento de aneurisma de aorta abdominal pode aumentar a incidência de TIH. Relatamos dois casos em que o uso de heparina durante tratamento endovascular de aneurisma de aorta abdominal estava associado ao aparecimento de TIH.

    Full Text Available This study aims at the analysis of the lexicon in English of the two professional areas, telecommunications and finance, affected by the crises of the recent years: the 90s dot-com bubble and the present-day Credit Crunch. Both crises share a common context of wealth and cultural complexity, being the root for the coinage of innovative specialised terms and collocations. Our study is specifically aimed at unveiling the lexical coverage of both crises, in terms of technolects and their context, evolving in several phases. First, two corpora of specialised, semi-specialised and general texts from the domains’ digital periodicals will be characterized according to lexical relevance and terminological volume, to see the extent in which they are lexically connected or diverge when experiencing a critical situation like a crisis. Finally, clarifying how far these two disciplines have related during the last critical years will hopefully provide some clues for the lexical ethnography of two institutionalised ways of thinking.Este estudio se dirige hacia el análisis del léxico en ingles en dos áreas profesionales, la tecnología y las finanzas, muy afectadas por las crisis de estos últimos años: la de la burbuja tecnológica y la llamada crisis del crédito, en la que nos encontramos inmersos.

  16. A crise da masculinidade: uma crítica à identidade de gênero e à literatura masculinista

    Directory of Open Access Journals (Sweden)

    Sergio Gomes da Silva

    Full Text Available Nos últimos anos, tem se discutido acerca da atual crise da masculinidade. O “novo homem” estaria em crise porque não encontraria modelos identitários hegemônicos para descrever sua nova condição masculina. Os reflexos dessa crise se devem à maior participação das mulheres no campo do trabalho, do avanço da tecnologia no campo da sexualidade, na pluralidade de papéis e identidades sexuais, na redefinição do papel de pai, na maior preocupação com o corpo e com a estética e a tentativa de manter e sustentar um modelo hegemônico único no papel masculino. A partir disto, o presente trabalho objetiva analisar a atual crise da masculinidade, a partir de uma crítica do conceito de identidade de gênero e da literatura masculinista enquanto representantes dos men´s studies. Propõe-se, como saída mais ética, a definição do sujeito de acordo com o neopragmatismo lingüístico.

  9. A further update on possible crises in nuclear-matter theory

    2015-01-01

    The ancient problem of the saturation of symmetric nuclear matter is reviewed with an update on the status of the crises that were identified at an early stage by John Clark. We discuss how the initial problem with variational calculations providing more binding than the two hole-line contribution for the same interaction was overcome by calculations including three hole-line contributions without however reproducing the empirical nuclear saturation properties. It is argued that this remaining problem is still open because many solutions have been proposed or ad hoc adjustments implemented without generating universal agreement on the proper interpretation of the physics. The problem of nuclear saturation therefore persists leading to the necessity of an analysis of the way the nuclear saturation properties are obtained from experimental data. We clarify the role of short-range correlations and review results for nuclear saturation when such ingredients are completely taken into account using the Green's func...

  11. The Food Crises and Political Instability in North Africa and the Middle East

    Lagi, Marco; Bar-Yam, Yaneer

    2011-01-01

    Social unrest may reflect a variety of factors such as poverty, unemployment, and social injustice. Despite the many possible contributing factors, the timing of violent protests in North Africa and the Middle East in 2011 as well as earlier riots in 2008 coincides with large peaks in global food prices. We identify a specific food price threshold above which protests become likely. These observations suggest that protests may reflect not only long-standing political failings of governments, but also the sudden desperate straits of vulnerable populations. If food prices remain high, there is likely to be persistent and increasing global social disruption. Underlying the food price peaks we also find an ongoing trend of increasing prices. We extrapolate these trends and identify a crossing point to the domain of high impacts, even without price peaks, in 2012-2013. This implies that avoiding global food crises and associated social unrest requires rapid and concerted action.

    Full Text Available A integração comercial e financeira global fortaleceu a classe capitalista em relação ao proletariado em cada país ao permitir às transnacionais deslocar suas empresas para países em que o custo da mão de obra é menor. A crise colheu a América Latina pela fuga das divisas fortes, extinção do crédito externo e queda das exportações, das inversões estrangeiras e das remessas dos emigrados. A crise se generaliza com as demissões em massa, a difusão do pânico que faz o crédito encolher, derrubando as vendas de bens de maior valor e os investimentos. Os governos do Primeiro Mundo trataram de resgatar os seus bancos falidos, comprando parte do seu capital ou sua totalidade com recursos do Tesouro. No Brasil, o governo faz que os bancos públicos estendam o crédito aos setores abandonados pelos bancos privados e baixem os juros que cobram. Os governos latino-americanos estimulam o mercado interno a absorver a produção que não enontra mais compradores no exterior mediante redistribuição da renda e aumento do investimento público. Nos últimos seis anos, os emergentes cresceram 50%, enquanto os industrializados cresceram apenas 10%, o que ampliou o número de nações cuja coordenação é indispensável para que a crise mundial possa ser domada do G-7 para o G-20. Uma das lições da crise é que, em lugar da globalização financeira, o povo de cada país deve ter o direito de decidir como seu excedente social deve ser administrado. A guarda do dinheiro do público e o seu empréstimo a investidores e consumidores devem ser reservados ao poder público e a entidades associativas sem fins de lucro.Global commercial and financial integration has strengthened the capitalist class in comparison with the proletariat around the globe as it permitted multinationals to relocate their companies to countries in which the cost of the labor force was lower.

    Cem Okan Tuncel

    Full Text Available The main aim of this paper is to investigate on banking crises which stemming from asymmetric knowledge problems in financial system. Asymmetric information and its related problems have a great influence on the functioning of financial markets. Finance literature underlines that banking firms are special intermediaries due to systemic risk concerns. In post liberalization interest rate tends to rise and moral hazard and adverse selection problem exist at firm level in banking business because of lack of adequate supervision. As is typically argued, unless liberalization is accompanied by sufficient prudential supervision of the banking sector, it will result in excessive risk taking by financial intermediaries and a subsequent crisis. In this paper excessive risk taking behavior of banking firms analyze with using a theoretical framework of New Keynesian that the “credit rationing model” offers, and moral hazard, adverse selections problems causing bank failure are discussed.

We argue that institutional changes need to be systemic, amounting to the construction of a new social structure of accumulation (SSA or mode of regulation (MOR, which we call an SSA of embedded communitarian liberalism. Five institutional spheres are introduced which are in need of systemic change, due to the entrenched contradictions and problems which the current set of institutions generate. These involve firstly institutions within the world-system of finance and production; secondly relating to finance versus industry; thirdly capital versus labor; fourthly state systems of production; and fifthly the interlinking of state, community and ecology.

    Health diplomacy has increasingly become a crucial element in forging political neutrality and conflict resolution and the World Health Organization has strongly encouraged its use. Global turmoil has heightened, especially in the Middle East, and with it, political, religious, and cultural differences have become major reasons to incite crises. The authors cite the example of the human stampede and the deaths of over 2000 pilgrims during the 2015 annual Haj pilgrimage in Mecca. The resulting political conflict between Iran and Saudi Arabia had the potential to escalate into a more severe political and military crisis had it not been for the ministers of health from both countries successfully exercising "soft power" options. Global health security demands critical health diplomacy skills and training for all health providers. (Disaster Med Public Health Preparedness. 2016;page 1 of 4).

    1994-11-01

    This paper addresses US energy security in the post-Cold War era for a conference on energy security jointly sponsored by the Department of Energy and the National Defense University. It examines the evolving nature of energy security based on analysis of past crisis-inducing events and-discusses potentially important geopolitical, environmental, regulatory, and economic developments during the next twenty-five years. The paper steps beyond the traditional economic focus of energy security issues to examine the interplay between fundamental economic and technical drivers on the one hand, and political, environmental, and perceptual phenomena, on the other hand, that can combine to create crises where none were expected. The paper expands on the premise that the recent demise of the Soviet Union and other changing world conditions have created a new set of energy dynamics, and that it is imperative that the United States revise its energy security perspective accordingly. It proceeds by reviewing key factors that comprise the concepts of ``energy security`` and ``energy crisis`` and how they may fit into the new world energy security equation. The study also presents a series of crisis scenarios that could develop during the next twenty-five years, paying particular attention to mechanisms and linked crisis causes and responses. It concludes with a discussion of factors that may serve to warn analysts and decision makers of impending future crises conditions. The crisis scenarios contained in this report should be viewed only as a representative sample of the types of situations that could occur. They serve to illustrate the variety of factors that can coalesce to produce a ``crisis.``

As with adults, pediatric patients with HTN can present with hypertensive crises include hypertensive urgency and hypertensive emergencies. However, pediatric blood pressure problems have a greater chance of being from secondary causes of HTN, as opposed to primary HTN, than in adults. Thorough evaluation of a child with a hypertensive emergency includes accurate blood pressure readings, complete and focused symptom history, and appropriate past medical, surgical, and family history. Physical exam should include height, weight, four-limb blood pressures, a general overall examination and especially detailed cardiovascular and neurological examinations, including fundoscopic examination. Initial work-up should typically include electrocardiography, chest X-ray, serum chemistries, complete blood count, and urinalysis. Initial management of hypertensive emergencies generally includes the use of intravenous or oral antihypertensive medications, as well as appropriate, typically outpatient, follow-up. Emergency department goals for hypertensive crises are to (1 safely lower blood pressure, and (2 treat/minimize acute end organ damage, while (3 identifying underlying etiology.

    Full Text Available O objetivo deste artigo, apoiado nos principais indicadores da economia global e nacional, é promover uma análise dos efeitos da crise mundial e as perspectivas de crescimento da economia brasileira no período de 2013-2015. O referencial teórico está apoiado nas Teorias Keynesiana, Neoinstitucionalista e das Finanças Públicas. Trata-se de um artigo bibliográfico, descritivo e qualitativo, cujas discussões estão baseadas nas projeções contidas nos relatórios das principais instituições multilaterais e nacionais brasileiras, em especial nas variáveis econômicas mais relevantes como o crescimento da economia mundial, do comportamento do nível de emprego e da inflação. Os resultados das discussões, a partir das análises dos documentos citados, evidenciam que a crise econômica mundial continua impactando de forma preocupante na maioria dos países, em especial, dos países membros da Zona do Euro e Estados Unidos, e que o desempenho da economia brasileira deverá crescer num ritmo menor nos próximos anos. Essas constatações permite concluir que se faz necessário a definição de um diagnóstico consistente para o Brasil, que permita uma mudança estrutural no potencial de expansão da economia do país, em especial, preparando de forma mais adequada o seu ambiente macro e microeconômico.

    Full Text Available O artigo procurar explorar a ideia de que no Brasil dos dias atuais vive-se numa situação de mal-estar institucional e crise política fortemente concentrada no plano da subjetividade política, ou seja, dos atores, ideias e projetos de sociedade. Busca discutir a recente crise do Senado como expressão dessa situação, vendo-a também como reflexo de um quadro mais amplo, que afeta os Parlamentos modernos de modo geral e poderia ser explicado como derivando de um cerco que o decisionismo governamental e as pressões sociais fazem sobre o Poder Legislativo, fazendo que perca eixo e capacidade de ação. Repercutindo os traços dominantes da época atual, os sistemas políticos e, por extensão, os Parlamentos tornam-se menos capazes de interagir de modo virtuoso com a cultura e as estruturas sociais derivadas dos novos termos da vida globalizada, ou seja, com sociedades plurais, fragmentadas, reflexivas, velozes e explosivas.This paper aims to explore the idea that we are currently facing a situation of institutional unrest and political crisis strongly concentrated on political subjectivity, that is, on players, ideas and projects of society. It attempts to discuss the recent crisis in Brazil's Senate as an expression of this situation, but also as a reflection of a wider framework, which affects modern Parliaments in general and could be seen as resultant from a siege laid by government decisionism and social pressures to the Legislative branch, depriving it from its axis and capacity to act. Echoing the dominant features of the present time, political systems and, by inference, Parliaments are rendered less able to interact in a virtuous way with culture and social structures that derive from the new terms of globalized life, that is, with plural, fragmented, reflexive, quick and explosive societies.

    Full Text Available Este ensaio explora o conceito de crises de fraternidade aplicando-o ao contexto dos conflitos humanos ligados à pós-colonialidade em Moçambique, inspirando-se no conceito de fraternidade desenvolvido pelo filósofo Emmanuel Lévinas. O material analisado é de natureza literária: dois romances recentes, que desenvolvem o tema das reacções emocionais à Guerra Civil ocorrida na década de 1980; e materiais memorialistas produzidos em torno à história controversa de uma mulher branca que optou pela cidadania moçambicana no período pós-Independência. A noção de "autoctonia" é explorada por relação à diversificação étnica no contexto pós-colonial. O artigo propõe uma complexificação do conceito antropológico de "alteridade" e rejeita as concepções reducionistas da história da nossa disciplina que têm vindo a difundir-se recentemente.This essay applies the concept of crises of fraternity to the human conflicts that accompanied the post-colonial moment in Mozambique, drawing its inspiration from Emmanuel Lévinas' philosophical concept of "fraternity". The paper analyses literary materials: two recent novels dealing with the emotional reactions to the Civil War of the 1980's; and memorialist records produced around the perplexing story of a white woman who opted for Mozambican citizenship in the post-Independence period. The notion of "autochtony" is explored by reference to the process of ethnic diversification in the post-colonial moment. The article argues for a complexification of the anthropological notion of "alterity" and rejects the reductionist views of the history of our discipline that have recently become widespread.

    Full Text Available George Gershwin, renowned composer and pianist, well known for his popular works, died on the 11th July 1937 due to a brain tumor. His neurological symptoms first appeared on that same year, in February, with a simple olfactory partial seizure, characterized by an unpleasant smell of burnt rubber (uncinated seizure. He later had a quick clinical descend, with severe headache that occurred in bouts, dizziness, coordination compromise and olfactory seizures, eventually lapsing into a coma on the 9th July 1937. It was then that a gliomatosus cyst was diagnosed, which on microscopic examination proved to be a "glioblastoma multiforme". Despite the surgical intervention, Gershwin died soon after the procedure without recovering his consciousness. We make a brief review of Gershwin's neurologic disease, with emphasis on the initial symptoms, namely the uncinated seizures.O célebre pianista e compositor George Gershwin, renomado pelas suas composições harmônicas e de apelo popular, faleceu em 11 de Julho de 1937 como consequência de um tumor cerebral. Seus sintomas neurológicos tiveram início em fevereiro daquele ano com uma crise epiléptica de tipo uncinado. Posteriormente houve rápida deterioração do quadro com cefaléia intensa, acompanhada por tonturas, até que em 9 de Julho de 1937 Gershwin foi internado em coma, tendo então o diagnóstico de tumor cerebral. Foi realizada a remoção cirúrgica parcial de tumor cístico, cujo exame anátomo-patológico revelou tratar-se de um glioblastoma. Gershwin faleceu logo após a neurocirurgia, sem ter ao menos recobrado a consciência. Fazemos uma breve revisão sobre a enfermidade neurológica de Gershwin, com ênfase aos sintomas iniciais da doença, as crises uncinadas.

    Marcelo Brutti Righi

    Full Text Available Com a crescente globalização, os mercados financeiros do mundo todo passaram a apresentar maior integração. Tal relacionamento entre mercados possui como implicação um termo que vem atraindo a atenção de profissionais e acadêmicos, a transmissão de volatilidade. Dessa forma, o presente trabalho tem como escopo analisar a transmissão internacional de volatilidade no mercado brasileiro. Para tanto, é utilizado um modelo Garch multivariado com parametrização BEKK. Com base nesse modelo, são estimados os relacionamentos bivariados entre o mercado brasileiro, representado pelo índice Ibovespa, e os mercados americano, argentino, mexicano e chinês, utilizando-se de índices representativos de 4 de janeiro de 2000 até 31 de março de 2010, totalizando 2667 cotações. A amostra foi dividida em três partes, representando os períodos anteriores, durante e posteriores à crise do subprime de 2007/2008. Os resultados obtidos permitem concluir que, durante a crise de 2008, de forma geral, houve mudança na direção da transmissão de volatilidade entre o mercado brasileiro e os demais estudados, de forma ao Brasil passar a exercer maior influência na volatilidade condicional desses, por ter sofrido menores consequências com a crise financeira. Além disso, após o período de turbulência causado pela crise de 2008, o relacionamento da volatilidade entre o mercado brasileiro com os demais passou a ser menos assimétrico do que no período anterior a crise.

    Full Text Available RATIONALE: Metabolic acidosis induced by topiramate is a well documented but infrequent adverse event. The objective was to demonstrate the lowering of carbon dioxide serum levels, which is usually asymptomatic but may facilitate the occurrence of metabolic acidosis in patients using topiramate. METHODS: We evaluated, prospectively, the carbon dioxide serum levels of 18 patients seen at the epilepsy clinic of our university hospital, before and 3 months after introducing topiramate. RESULTS: Five patients were female and 13 were male, age ranging from 2 to 16 years old (mean=9.3. Carbon dioxide mean serum levels were 25 and 21.2 mmol/L (normal = 22 to 30, before and 3 months after introducing topiramate, respectively. Dose ranged from 2.08 to 11.76 mg/kg/day (mean=6.7mg/kg/day. Adverse events were anorexia, nausea and somnolence. CONCLUSION: We conclude that the lowering of carbon dioxide serum levels induced by topiramate is mostly asymptomatic, but may facilitate the occurrence of metabolic acidosis. Since patients in use of topiramate have refractory epilepsy, they may need epilepsy surgery, and must be carefully monitored for the risk of metabolic acidosis during surgery.INTRODUÇÃO: Acidose metabólica induzida por topiramato é evento adverso pouco frequente, mas bem documentado. Nosso objetivo foi demonstrar a diminuição dos níveis de dióxido de carbono, muitas vezes assintomática, mas que pode predispor ao aparecimento de acidose metabólica. MATERIAL E MÉTODO: Avaliamos prospectivamente os níveis de dióxido de carbono de 18 pacientes acompanhados no ambulatório de epilepsia infantil da UNICAMP, antes e 3 meses após o início do uso de topiramato. RESULTADOS: Foram avaliados 18 pacientes com idade entre 2 e 16 anos (média = 9,3 anos. Cinco pacientes eram do sexo feminino e 13, do sexo masculino. Os níveis médios de dióxido de carbono antes e após o uso de topiramato foram 25 e 21,2 mmol/L (normal = 22 a 30

    Full Text Available Early identification of arrhythmias in dogs showing doxorubicin-induced cardiomyopathy was studied. Ten healthy dogs were assigned to groups A (n=5 and B (n=5. Dogs from group B were given doxorubicin 30mg/m² intravenously, every 21 days, until a cumulative dose of 180mg/m² or 240mg/m² was reached. Dogs from group A (used as control were administered saline intravenously at the same group B intervals. As soon as myocardium dysfunction was observed in dogs from group B, determined by a shortening fraction below 20%, increased E-point to septal separation above 0.7cm, and increased end-systolic left ventricular volume index (61.4ml/m², a 24-hour Holter was recorded in all dogs from both groups. There was an increase of minimum heart rate (44.6% and mean heart rate (41.7% in animals from group B in comparison with the control animals. Either supraventricular or ventricular arrhythmias were observed, despite group B dogs showed higher occurrence of supraventricular arrhytmias. Holter monitoring is efficient in early determination of heart rate and cardiac rhythm alterations in dogs showing doxorubicin-induced myocardial dysfunction.O estudo consistiu na identificação precoce da ocorrência de arritmias em cães com cardiomiopatia dilatada experimental induzida pela doxorrubicina (DOX.

    Full Text Available Durante a aplicação de uma força constante e leve, eventos mecânicos e bioquímicos se sucedem, resultando na movimentação dentária. O deslocamento dentário inicial, ainda nos limites da largura alveolar, leva ao extravasamento do fluido do ligamento periodontal, compressão parcial dos vasos sanguíneos e distorção mecânica de fibras e células do ligamento periodontal. As alterações do fluxo sanguíneo acarretam a liberação de mediadores bioquímicos que resultam no recrutamento de osteoclastos e, conseqüentemente, na remodelação óssea. Neste trabalho, os autores se propuseram a avaliar as alterações do periodonto de inserção durante a movimentação dentária induzida em ratos. A amostra foi constituída por nove ratos, divididos em três grupos, cujos primeiros molares superiores direitos foram movimentados utilizando-se uma força de 0,5 N. Os primeiros molares superiores esquerdos desempenharam o papel do grupo controle. Os animais do grupo 1 tiveram seus dentes movimentados por três dias, os do grupo 2, por sete dias e os do grupo 3, por catorze dias. Os cortes histológicos foram corados com hematoxilina e eosina e analisados em microscopia óptica. Verificou-se, durante os primeiros dias de aplicação de força, um predomínio dos fenômenos de neoformação óssea no lado de tração e de reabsorção óssea no lado de pressão

    Full Text Available Considerando que a irracionalidade dos agentes no mercado se acentua em crises financeiras, esse artigo objetivou verificar a existência do Efeito Segunda-Feira em períodos de crise e de estabilidade no Brasil, através da análise do Ibovespa. Para tanto, o comportamento do índice foi modelado através de técnicas estatísticas de séries de tempo (modelos autorregressivos e de heteroscedasticidade condicional, para o período de janeiro de 2003 até abril de 2012, agrupando os dados em séries diferentes, com o intuito de identificar os períodos de crise. Foi identificado um retorno médio estatisticamente inferior nas segundas-feiras somente para os períodos ambientados pela crise do Subprime e pela Crise do Euro, sugerindo que crises financeiras são favoráveis para a existência do Efeito Dia da Semana para as segundas-feiras. Explicações para esse fato podem ser pautadas na irracionalidade dos agentes no mercado de capitais, que é acentuada em ambientes de crise, onde a sensação de medo é mais forte do que os fundamentos analíticos para a precificação dos ativos financeiros.

    Full Text Available Abstract: In this article we examined the impact of economic crises in the years 2008/2009 on the logistics industry in old member states EU-15 and the new EU member states. The emergence of the economic crisis in 2008/2009 when the states of the old members of EU-15 and new EU member states were the first time subjected to the effects of the crisis inside the single entity-the European Union. Research question: The basic research question is: Were implications of economic crises in the years 2008/2009 in logistics industry in heterogenic states of European Union; old member states EU-15 and the new EU member states different? Purpose:We wanted to determine how the logistics companys in old member States EU (15 and in the new EU member states adapt to the new circumstances caused by economic crises in the years 2008/2009. Method: Economic crises are complex multifunctional phenomenon. Analysing complexity of the changes of the state of economic system need to supplement the pure scientific approach with other types of research work, more holistic approach, which is commonly used in Comparative economics. In this article we combine both. In empirical part we used appropriate parametric and non-parametric tests of differences between old and new member states of the European Union. We used Pearson's chi-squared test (Pearson, 1900, p. 157-175. Results: In the article we studied changes ocured by economic crises in the years 2008/2009 in the European logistics industry. We found that the logistics companies in the old EU member states EU-15 and in the new EU member states differently adapt to the implications of economic crises in the years 2008/2009. EU hasn’t adopted and implemented the harmonised economic policy, which will solve the »North-South« problem in logistics industry and find a way to operate systemically in global environment.

    Crisis and emergency psychiatric services are an integral part of the healthcare system, yet there are no standardized measures for programs providing these services. We developed the Crisis Reliability Indicators Supporting Emergency Services (CRISES) framework to create measures that inform internal performance improvement initiatives and allow comparison across programs. The framework consists of two components-the CRISES domains (timely, safe, accessible, least-restrictive, effective, consumer/family centered, and partnership) and the measures supporting each domain. The CRISES framework provides a foundation for development of standardized measures for the crisis field. This will become increasingly important as pay-for-performance initiatives expand with healthcare reform.

    Full Text Available BACKGROUND: Hypothermia is a frequent event in severe acute pancreatitis (AP and its real effects on the normal pancreas have not been well demonstrated. Moreover, neither have its effects on the outcome of acute pancreatitis been fully investigated. One hypothesis is that oxidative stress may be implicated in lesions caused or treated by hypothermia. AIM OF THE STUDY: To investigate the effect of hypothermia in cerulein-induced acute pancreatitis (CIAP in rats and the role played by oxidative stress in this process. METHODS: Male Wistar rats were divided into hypothermic and normothermic groups. Hypothermia was induced with a cold mattress and rectal temperature was kept at 30ºC for one hour. Acute pancreatitis was induced with 2 doses of cerulein (20 ìg/kg administered at a one-hour interval. Serum amylase, pancreas vascular permeability by Evan's blue method, pancreas wet-to-dry weight ratio and histopathology were analyzed in each group. RESULTS: When compared with normothermic rats, hypothermic animals, with cerulein-induced acute pancreatitis, showed higher levels of pancreatic vascular permeability (p BACKGROUND: Hipotermia é um evento freqüente em episódios de pancreatite aguda, contudo seu efeito real sobre pâncreas normal ainda não esta bem demonstrado. Além do mais, o efeito da hipotermia no decorrer da pancreatite aguda também não está completamente esclarecido. Uma das hipóteses sobre as causas das lesões causadas ou tratadas por hipotermia aventa a implicação de estresse oxidativo. OBJETIVOS: Investigar o efeito da hipotermia em ratos com pancreatite aguda induzida por ceruleína e o papel do estresse oxidativo neste processo. MÉTODOS: Ratos Wistar machos foram divididos em grupos hipotérmicos e normotérmicos. Hipotermia foi induzida com uma bolsa gelada de forma que a temperatura retal permanecesse em 30ºC por uma hora. Pancreatite aguda foi induzida com duas aplicações de ceruleína (20 ìg/kg administradas

  20. The Nature of Punctuational Crises and the Spenglerian Model of Civilization

    Clube, S. V. M.

    acknowledged dispensers of prognosis and mitigation who endorsed the adverse implications of 'blazing stars' (astrologers, soothsayers etc.) were commonly impugned and censured. Nowadays, of course, we are able to recognise that the Earth's environment is not only one of essentially uniformitarian calm, as formerly assumed, but one that is also interrupted by 'punctuational crises', each crisis being the sequence of events which arises due to the fragmentation of an individual comet whose orbit intersects the Earth's. That even modest crises can arouse apprehension is known through the circumstances of the nineteenth century break-up of Comet Biela. Indeed it seems that these crises are rather frequently characterized by relatively violent (paradigm shifting) transmutations of human society such as were originally proposed by Spengler and Toynbee more than sixty years ago on the basis of historical analysis alone. It would appear, then, that the historical fear of comets which has been with us since the foundation of civilization, far from being the reflection of an astrological perception of the cosmos which was deranged and therefore abandoned, has a perfectly rational basis in occasional cometary fragmentation events. Such events recur and evidently have quite serious implications for society and government today. Thus when cosmic danger returns and there is growing awareness of the fact, we find that society is capable of becoming uncontrollably convulsed as 'enlightenment' spreads. A revival of millenarian expectations under these circumstances, for example, is not so much an underlying consequence but a deviant manifestation of the violent turmoil into which society falls, often to revolutionary effect.

    Full Text Available O capitalismo é um sistema econômico inerentemente contraditório e instável, com variações que se processam no tempo e no espaço. Após a derrocada do socialismo real, o capital assumiu uma missão civilizatória cada vez mais ampla, distribuindo suas benesses e contradições em nível global. Neste artigo se pretende expor as mudanças no capitalismo contemporâneo a partir do fordismo até a crise de 2008, relacionando-as com as desigualdades econômicas e sociais. A recente crise – que teve origem no setor imobiliário (subprime dos Estados Unidos e contagiou o mercado financeiro mundial, lançando o mundo em mais uma onda de recessão – parece apontar para um cenário pessimista no futuro. No entanto, alguns mecanismos presentes nas democracias modernas propiciaram, a um variado conjunto de movimentos, a contestação da atual ordem econômica e social em escala global – sugerindo a possibilidade de cenários alternativos.Palavras-chave | Capitalismo; crise; democracia; desigualdades sociais.Código JEL | G01; G28; P17. CONTEMPORARY CAPITALISM, SOCIAL INEQUALITY AND THE CRISIS OF 2008AbstractCapitalism is an economic system inherently contradictory and unstable, with variations that take place in time and space.

    Full Text Available O presente artigo argumenta que a decadência do ensino público é, nos Estados Unidos, principalmente, um produto de contradições impostas externamente que são inerentes à educação na sociedade capitalista, agravadas em nossos tempos pelas condições de estagnação econômicas, em especial nas economias desenvolvidas, e pelos efeitos do próprio movimento de reforma conservador. Para tal fim, apresenta os pressupostos da política educacional e os desdobramentos e consequências para a educação pública – a partir de uma perspectiva histórica – no contexto da crise estrutural do capital nos Estados Unidos. Explicita-se a crise estrutural associada a uma nova fase do capitalismo: o capital monopolista-financeiro, caracterizada por: (1 estagnação econômica nas economias capitalistas desenvolvidas; (2 uma mudança dramática em direção à financeirização, as bolhas especulativas como meio de expansão econômica; e (3 a rápida concentração (e monopolização de capital em uma escala global, mostrando, como uma consequência do lento crescimento endêmico para as economias desenvolvidas, que as grandes corporações que dominam a economia mundial atual são obrigadas a procurar novos mercados para investimento, fora de suas áreas tradicionais de atuação, levando à aquisição e privatização de elementos-chave da administração do Estado. A contrapartida política do capital monopolista-financeiro é, portanto, a reestruturação neoliberal, em que o Estado é cada vez mais ocupado por interesses privados. Apresentando diversos autores da área da economia e com base em Marx – o texto vai informando a relação de degradação e desvalorização da educação pública. Finaliza suas análises indicando a necessidade de uma longa revolução, para criar, entre outras coisas, uma nova educação ligada à comunidade, e desenvolvida a partir das necessidades reais das pessoas.

  3. Um olhar sistêmico sobre a crise norte-americana

    CHRISTIAN CARVALHO GANZERT

    Full Text Available RESUMO No contexto contemporâneo, a economia global pode ser descrita como um sistema baseado em agentes que, quando associados, manifestam seus próprios meios e fins. A crise das hipotecas subprime nos Estados Unidos é um bom exemplo das implicações desse tipo de relacionamento. Ela está diretamente relacionada a poderosos laços de realimentação, compostos por uma série de variáveis que amplificaram o fato de as famílias americanas terem se endividado em ritmo maior do que a sua distribuição de riqueza, prejudicada pela externalização da produção. Há atualmente uma nova estrutura na economia internacional, em que as ex-nações subdesenvolvidas estão mais bem posicionadas no cenário macroeconômico e têm maior poder do que antes - uma consequência do necessário rearranjo sistêmico. Diante dessa complexa dinâmica, a função de inteligência que deveria controlar e garantir a estabilidade sistêmica falhou em perceber a dinâmica e os impactos da nova cultura atrelada ao comportamento do capital contemporâneo, para evitar a perda da hegemonia. Observando-se ex post facto, por meio de um enfoque sistêmico, a crise econômica americana pode ser definida como tendo suas raízes nas premissas de todo o arcabouço cultural da globalização que acabou por conduzir à externalização da produção. Assim, o contexto sistêmico desta análise aponta que a cultura, como importante gerador e amplificador, deve ser o principal foco dos intentos de análise do atual contexto socioeconômico global.

To compare the efficacy and safety of urapidil (i/v solution 5 mg/ml in 5 and 10 ml ampoules and enalaprilat (i/v solution 1.25 mg/ml in 1 ml ampoules in the treatment of complicated hypertensive crises in patients with arterial hypertension, 1-3 degrees. Material and methods. Patients with complicated hypertensive crisis (n=70 were included into the comparative randomized study. Patients were randomized for treatment with urapidil (the initial dose 12.5 mg; if there was no effect after 15 minutes it was possible to re-infused urapidil 12.5 mg or enalaprilat (the initial dose 1.25 mg. The frequency of target blood pressure (BP achievement, BP and heart rate dynamics, as well as safety of treatment were evaluated in groups during 6 hours. Results. The frequency of target BP achievement in the urapidil treatment group was higher than this in enalaprilat group (96.7 vs 73.3%; p<0.001, for the first hour systolic BP (SBP in the urapidil group reduced from 210.5±13.6 to 157.8±8.3 mmHg (p<0.05, and diastolic BP (DBP - from 115.7±8.5 to 86.9±9.1 mmHg (p<0.05. In the enalaprilat group in the first hour SBP reduced from 208.1 to 182.5 mmHg (p<0.05, DBP — from 114.8 to 95.0 mmHg (p<0.05. During next 6 hours the urapidil group demonstrated longer lasting antihypertensive effect in comparison with enalaprilat. Both drugs did not have a significant effect on heart rate and showed no significant adverse events. In next 72 hours no one acute vascular event was registered in the patients of both groups. Conclusion. Urapidil is an effective and safe drug for arresting of complicated hypertensive crises. Its efficacy is not inferior to this of enalaprilat.

En d'autres termes, à notre époque les démocraties seraient devenues le règne des espaces temporels toujours plus restreints dont la nanoseconde peut être considérée comme le symbole.Mais quelles sont les retombées de ce processus sur l’idée de futur ?Si au cours du XXe siècle, l'image du futur en tant qu'espace regorgeant de possibilités s'est progressivement affaiblie, c'est essentiellement ce nouveau siècle qui a mis en relief le croisement entre l'accélération sociale d'un côté, et la crise du futur de l'autre.L'augmentation du rythme de vie ainsi que l'accélération des processus de transformation économique, sociale et technologique, annihilent le futur. En raison de la pression temporelle ainsi produite, le futur a tendance à se replier sur le présent, se consume avant même d’être représenté. À leur tour, les nouveaux idéaux d’instantanéité et de mobilité ont une incidence négative sur la conception de la politique en tant que champ d'action ouvert pour le contrôle des processus de changement, et la mettent en crise.Dans les conclusions l’article indique toutefois la possibilité d’une vision de la politique à même de se soustraire aux impératifs de l’accélération. Une telle vision s’allie aux « savoirs situés » féminins, à la multiplicité des temps et à la centralité de la vie quotidienne qu’ils renferment. Ensemble, ils disposeraient peut-être encore du potentiel de reconstruction de formes d’agora.Today, Western societies appear more and more like ‘nanocracies‘, as it has been proposed to rename them, because of the absolute pre-eminence of the dimension of speed within them.

    Full Text Available This explorative study presents an empirical examination of the connection between motivation and the measures individuals take to prevent everyday accidents and prepare for crises. Positional factors (age and gender and situational factors (education, size of locality, and household composition are included because the literature highlights their importance. The study used data gathered in a 2010/2011 poll of randomly selected Swedish residents aged 16–75 (N = 2000; 44.8% response rate. A factor analysis reduced the theoretical model for situational motivation (Guay, Vallerand, & Blanchard, 2000 from four to two dimensions: motivation and amotivation. Subsequent regression analyses statistically confirmed the connection between motivation or amotivation and the extent to which individuals pursue preventative and preparedness measures, even when accounting for positional and situational factors. These findings underscore the need for continued studies of individuals’ incentives to prevent accidents and prepare for crises and for the study of the nuances of (situational motivation and preventive/preparedness measures.

Êste foi conseguido, em um grupo de 6 enfermos, pela suspensão das drogas anticolinesterásicas, emprego da respiração artificial e alimentação por sonda nasogástrica — "repouso relativo". Outro grupo de 6 pacientes foi submetido ao "repouso absoluto" da junção neuromuscular, mediante o uso da respiração artificial, alimentação por sonda nasogástrica e curarização prolongada pela galamina. Em mais de 50% das crises observaram-se melhoras imediatas e acentuadas com o método de tratamento pelo "repouso" da junção neuromuscular, ao lado de redução significativa da taxa de mortalidade nas crises. A evolução mostrou que os pacientes que responderam melhor durante e logo após o tratamento da crise, tiveram, também, melhor evolução ulterior. Dos 12 enfermos somente um era portador de timoma e, mesmo nesse paciente, a evolução foi satisfatória. A sensibilidade inicial ao curare foi muito grande em todos os doentes submetidos à curarização prolongada, mas, em prazo relativamente curto (alguns dias, esta hipersensibilidade diminuiu sensivelmente. Apesar de todos os cuidados, as infecções respiratórias foram a regra, exigindo tratamento enérgico e bem orientado.

    Full Text Available A regulamentação da reforma do ensino da arquitectura em 1957 inicia um processo de transformações sucessivas no quotidiano dos cursos de arquitectura que irá culminar com uma crise no ano de 1969.Ao longo de uma década de funcionamento, a nova orgânica proposta pela reforma não conseguiu, na sua globalidade, introduzir uma nova pedagogia nem democratizar o funcionamento das escolas, ficando refém do autoritarismo do Ministério da Educação. No entanto, a sua rigidez científica e administrativa estimulou professores e alunos a desenvolver estratégias, quer de projecto, quer de reflexão e debate, que procuraram promover a função social do arquitecto atento aos problemas da sociedade e da cidade, por oposição ao arquitecto tecnocrático.Nos anos de 1968 e 1969 as duas escolas, tal como a universidade e a sociedade, politizam o seu discurso. Os estudantes e os professores reivindicam abertamente alterações profundas na gestão da escola, nos métodos pedagógicos e nos objectivos do ensino, exigindo a reforma da Reforma de 57.Este texto aborda os momentos críticos deste processo de consciencialização política e social dos estudantes, que procura recolocar o papel da Escola no debate sobre a formação e sobre a profissão de arquitecto. No final de 1969 as escolas de arquitectura estão em crise, porque a universidade está em crise, mas também porque a profissão está crise.

    Full Text Available Aborda-se, aqui, as causas profundas da crise e as formas que ela tomou durante os últimos cinco anos, particularmente sobre a gigantesca concorrência, verdadeira "guerra de moedas". Para além da "crônica de acontecimentos" da crise suas dimensões financeira e monetária, crise das dívidas "soberanas", o futuro e a "sobrevida" do euro busca-se a problemática que circunscreve esta crise desde 2008. O fio condutor, capaz de abarcar seu processo, continua sendo aquele da análise do processo real, baseado no método e na teoria de Marx, através da evolução do capitalismo de "concorrência". Revela-se a importância da concorrência e o fato de que, atualmente, ela também tende a se exacerbar. Evidenciam-se as novas condições de valorização do capital e a busca pelo lucro, em processos complexos de destruição-criação de valor e se ilustram, também, os mecanismos ligados à superacumulação do capital, à superprodução de mercadorias dela decorrentes. Marx nos ajuda a compreender que, para sobreviver, o capitalismo deve continuar "extorquindo" a mais-valia, a qualquer preço. É um imperativo absoluto para sua reprodução e o que hoje lhe confere um caráter predador e brutal em todos os domínios da vida social.

    Glutaryl-CoA dehydrogenase (GCDH) deficiency is a rare neurometabolic disorder that is considered treatable if patients are identified before the onset of acute encephalopathic crises. To allow early identification of affected individuals, tandem mass spectrometry-based newborn screening for GCDH deficiency has been started in Germany in 1999. We prospectively followed neonatally screened patients (n=38) and compared the neurologic outcome with patients from a historical cohort (n=62). In the majority of neonatally screened children, the onset of encephalopathic crises has been prevented (89%), whereas acute encephalopathic crises or progressive neurologic impairment was common in the historical cohort. Neonatal screening in combination with intensive management is effective--even assuming ascertainment bias in the historical cohort. Similar proportions of commonest mutations and biochemical phenotypes (high and low excretors) were found in neonatally screened and historical patients. However, potential predictor variables for mild clinical phenotypes are not yet known and thus a selection of these patients by newborn screening is not excluded. No patient was known to be missed by newborn screening from 1999 to 2005. In conclusion, this study confirms that newborn screening for GCDH deficiency in combination with intensive management is beneficial.

Em um sentido mais amplo, se trata de pensar o lugar da geografia na explicação da realidade em constante transformação. Se é possível pensar que, apesar de seus avanços, a Geografia vive um estado de crise? Deparamos-nos com a exigência de revelar seus sintomas e como consequência, a necessidade de construção de um caminho frente a necessidade de compreensão da realidade a partir da ou através da Geografia. A metageografia é a proposta de um caminho teórico-metodológico de superação do estado de crise en que se encontra a disciplina a partir da prática sócio-espacial como momento explicativo.
