This article discusses the status of workplace training in the United States, describes a model of how to conduct effective on-the-job training, and presents the results of a questionnaire based on a model designed to assess on-the-job training practices aboard Navy ships. The model views the on-the-job trainer as a coach who guides the trainee through a task using three steps: 1) assessment, 2) training, and 3) evaluation. The questionnaire was sent to over 5,000 shipboard supervisors; 2,321 responded. Results indicate that nearly 50% of the Navy supervisors who responded are not as effective as they could be. The implications of these findings for the civilian workplace are discussed. 相似文献

The on-going Coronavirus disease(COVID-19)outbreak in China has become the world's leading health headline and is causing major panic and public concerns.On January 30,2020,the World Health Organization(WHO)declared that the new coronavirus outbreak is a public health emergency of international concern.1 The virus has already had a direct impact on more than 10 million people in the city of Wuhan and has reached other parts of China as well,posing a health threat of unknown magnitude globally.As of February 8,2020,WHO reported 34,886 confirmed cases of COVID-19 globally,with 34,589 of them occurring in China(including 6101 severe cases and 723 deaths).A total of 288 other confirmed cases(with 1 death)have been reported in 24 countries,including Japan,Australia,Germany,and United States.2 However,these daily estimates are expected to rise even higher as reports from health authorities in China3 are gathered and near real-time updates of the Johns Hopkins virus dashboard are made 4 The outbreak has caused governments in various countries to take swift and protective measures.In China,these included putting cities on lockdown,5 implementing travel wamings/bans and cancellations,6 extending national holidays,and closing schools and postponing classes7. 相似文献
