    Um estudo epidemiolĂłgico transversal com todos os 808 professores da Rede Municipal de Ensino de VitĂłria da Conquista, Bahia, encontrou elevadas prevalĂȘncias de queixas de cansaço mental (70,1%) e de nervosismo (49,2%). Diversos fatores de risco associaram-se a cansaço mental e a nervosismo: idade >27 anos, ser mulher, ter filhos, escolaridade mĂ©dia, lecionar >5 anos, vĂ­nculo de trabalho estĂĄvel, trabalho em zona urbana, carga horĂĄria semanal >35h, renda >360 reais, sobrecarga domĂ©stica mĂ©dia/alta, nĂŁo ter atividades de lazer, alta demanda no trabalho e baixo suporte social. A classificação do trabalho docente, segundo o Modelo Demanda-Controle de Karasek, revelou os quadrantes "baixa exigĂȘncia" (40,3%) e "trabalho ativo" (39,7%), ambos com alto controle das atividades por parte dos professores. Professores em trabalho de "alta exigĂȘncia" e "trabalho ativo" apresentaram prevalĂȘncias de cansaço mental e de nervosismo mais elevadas que aqueles de "baixa exigĂȘncia".<br>An epidemiological cross-sectional study among the 808 teachers from VitĂłria da Conquista, State of Bahia, Brazil, revealed that most of them complained of mental tiredness (70,1%) and nervousness (49,2%). Several risk factors were statistically associated with mental tiredness and nervousness: age > 27 years, being female, having children, having secondary education, teaching for >5 years, stable job, working in urban areas, weekly work hours e"35 hours, income > BRL 360 (&plusmn; USD 185), medium/high domestic overload, having no leisure activity, high psychological demand at work and low social support. According to Karasek's demand-control model, teachers' work was classified in the "low strain" (40.3%) and "active work" (39.7%) quadrants, both with high control of activities by teachers. Teachers with "high strain" and "active work" presented higher prevalence of mental tiredness and of nervousness than those with "low strain" jobs

    The Vulnerable System: An Analysis of the Tenerife Air Disaster

    The Tenerife air disaster, in which a KLM 747 and a Pan Am 747 collided with a loss of 583 lives, is examined as a prototype of system vulnerability to crisis. It is concluded that the combination of interruption of important routines among interdependent systems, interdependencies that become tighter, a loss of cognitive efficiency due to autonomic arousal, and a loss of communication accuracy due to increased hierarchical distortion, created a configuration that encouraged the occurrence and rapid diffusion of multiple small errors. Implications of this prototype for future research and practice are explored.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68716/2/10.1177_014920639001600304.pd
