In particular, the National Bureau of Economic Research does not use the unemployment rate but prefers various employment rates to date recessions. Labor force participation rate
The labor force participation rate is the ratio between the labor force and the overall size of their cohort (national population of the same age range). In the West, during the later half of the 20th century, the labor force participation rate increased significantly because of an increase in the number of women entering the workplace. In the United States, there have been four significant stages of womens participation in the labour force: increases in the 20th century and decreases in the 21st century. Male labor force participation decreased from 1953 to 2013. Since October 2013, men have been increasingly joining the labour force. From the late 19th century to the 1920s, very few women worked outside the home. They were young single women who typically withdrew from the labor force at marriage unless family needed two incomes. Such women worked primarily in the textile manufacturing industry or as domestic workers. That profession empowered women and allowed them to earn a living wage. At times, they were a financial help to their families. Between 1930 and 1950, female labor force participation increased primarily because of the increased demand for office workers, womens participation in the high school movement, and electrification, which reduced the time that was spent on household chores.
He thought he had "borrowed [his] mothers spirit to show [him] around Hell" and that she was asleep in Scotland. The article Recurrent Postictal Depression with Cotard Delusion (2005) describes the case of a 14-year-old epileptic boy who experienced Cotards syndrome after seizures. His mental health history showed themes of death, chronic sadness, decreased physical activity in leisure time, social withdrawal, and disturbed biological functions. About twice a year, the boy had episodes that lasted between three weeks and three months. In the course of each episode, he said that everyone and everything was dead (including trees), described himself as a dead body, and warned that the world would be destroyed within hours. Throughout the episode, the boy showed no response to pleasurable stimuli, and had no interest in social activities. Pathophysiology
The underlying neurophysiology and psychopathology of Cotards syndrome might be related to problems of delusional misidentification. Neurologically, Cotards delusion (negation of the self) is thought to be related to Capgras delusion (people replaced by impostors); each type of delusion is thought to result from neural misfiring in the fusiform face area of the brain, which recognizes faces, and in the amygdalae, which associate emotions to a recognized face.The neural disconnection creates in the patient a sense that the face they are observing is not the face of the person to whom it belongs; therefore, that face lacks the familiarity (recognition) normally associated with it. This results in derealization or a disconnection from the environment.
