ABSTRACT
ABSTRACT Objective. To analyze the effectiveness of social distancing in the United States (U.S.). Methods. A novel cell-phone ping data was used to quantify the measures of social distancing by all U.S. counties. Results. Using a difference-in-difference approach results show that social distancing has been effective in slowing the spread of COVID-19. Conclusions. As policymakers face the very difficult question of the necessity and effectiveness of social distancing across the U.S., counties where the policies have been imposed have effectively increased social distancing and have seen slowing the spread of COVID-19. These results might help policymakers to make the public understand the risks and benefits of the lockdown.(AU)
RESUMEN Objetivo. Analizar la efectividad del distanciamiento social en los Estados Unidos. Métodos. Se empleó un método novedoso de contacto con teléfonos celulares (ping) para cuantificar las medidas de distanciamiento social de todos los condados de EE.UU. Resultados. Usando un enfoque de diferencia en diferencias los resultados indicaron que el distanciamiento social ha sido efectivo para reducir la propagación de la COVID-19. Conclusiones. A medida que los responsables de la formulación de políticas se enfrentan a la muy difícil cuestión de la necesidad y la eficacia del distanciamiento social en Estados Unidos, los condados en los que se han impuesto las políticas han aumentado efectivamente el distanciamiento social y en ellos se ha enlentecido la propagación de la COVID-19. Estos resultados pueden ayudar a los responsables de las políticas a hacer comprender a la población los riesgos y beneficios de las restricciones.(AU)

La Organización Mundial de la Salud (2013), alerta a los gobiernos a tomar medidas urgentes para prevenir accidentes de tránsito. Si no se intervienen, en el 2030 serán la quinta causa de muerte. Este estudio establece el perfil psicológico de conductores de vehículo infractores frecuentes de normas de tránsito, en una muestra de 295 adultos de ambos sexos. Utilizando el cuestionario factorial de personalidad 16PF-5 y una escala de creencias, conocimientos, y comportamientos sobre seguridad vial, se identificaron relaciones significativas entre conducta infractora y creencias, además de los factores de personalidad y variables específicas que predicen la propensión a las infracciones frecuentes de normas de tránsito.
The World Health Organization (2013) has alerted governments to take urgent measures to prevent traffic accidents. If no intervention is made, they will be the fifth leading cause of death in 2030. This study established the psychological profile of frequent offenders of traffic rules in a sample of 295 drivers of both sexes. Using the 16PF-5 Personality Questionnaire and a scale of beliefs, knowledge, and road safety behaviors, significant relationships between offending behavior and beliefs were identified, in addition to the specific personality factors and variables that predict susceptibility to frequent violations of traffic rules.
ABSTRACT
Medical research has entered the era of mega-science.The multidisciplinary collaboration has attracted great attention.besides studies on genes and the environment interaction,multidisciplinary research between natural sciences has received widespread recognition.However muhidisciplinary researches on the interaction between the gene and social factors or behavioral factors on health science deserve more emphasis.This article described development of multidisciplinary research and its features;analyzed importants of conducting multidisciplinary research between natural and social disciplines,and finally provided suggestions on research organization reform in order to promote the multidisciplinary research.
ABSTRACT
@#ObjectiveTo explore the state of intelligence and adaptive behavior of children with cerebral palsy and the correlation between them.Methods169 children with cerebral palsy were evaluated with Wechsler Intelligence Scale for Children (Chinese version) and the Infants-Junior Middle School Students' Social-Life Abilities Scale for the intelligence and the adaptive behavior.ResultsThe average scores of verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ) and full intelligence quotient(FIQ) of the patients were lower than the normal children and the average scores of PIQ and FIQ were less than 70; the PIQ deficiency was significant more than the VIQ deficiency(P<0.001). 93 cases had mental deficiency, including 43(46.23%) for mild, 36(38.71%) for moderate, 13(13.98%) for severe, 1(1.08%) for extreme severe. There were 113(66.86%) for the deficiency of full social-life abilities, 104(61.54%) for Self-Help, 147(86.98%) for Locomotion, 133 (78.70%) for Occupation, 73 (43.20%) for Communication, 115(68.05%) for Socialization, 90 (53.25%) Self-Direction. The damage of Locomotion was the most serious, while the damage of Communication was the least serious. The outcomes of Wechsler Intelligence Scale was significantly correlated with the Infants-Junior Middle School Students' Social-Life Abilities Scale(P<0.001).ConclusionThe cerebral palsy causes not only intelligent damage, but also intelligence deficiency in most patients and the major level of the intelligent deficiency is mild to moderate. The damage of the performance intelligence has more influence on the full scale intelligence in the children with cerebral palsy. Most of the children with cerebral palsy have inconsistent deficiency of different aspects of the adaptive behavior.
