Participation in education among older people

National random sample data on 4254 people in four adult age categories were analyzed with regard to enrollments in different kinds of education settings, enrollment motives, and barriers to enrollment. Further analysis compared participants to nonparticipants. Most adult enrollments were at the college or university level before age 40, in other settings thereafter, and instrumental motives were predominant across the lifespan. Lack of time and interest were major barriers to enrollment among older people, and those enrolled generally had higher prior educational attainments, were younger, and lived in urban or suburban locations.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44538/1/10755_2005_Article_BF01080356.pd

Estudo da confiabilidade e validade da utilização do hidropletismômetro para medida de edema no tornozelo Study of the reliability and validity of the water plethysmographer for use in measurement of the edema at the ankle/foot

Instrumentos confiáveis e válidos são necessários para avaliar a efetividade das técnicas de reabilitação. O objetivo deste estudo foi avaliar a confiabilidade e a validade do Hidropletismômetro. Quatorze sujeitos com idade entre 18 e 59 anos foram selecionados para participar do estudo. Os tornozelos foram avaliados por dois examinadores treinados com o Hidropletismômetro. Três medidas de cada tornozelo foram obtidas pelos examinadores de forma aleatória para investigar a confiabilidade intra e inter-examinadores. Foram também obtidas vinte e seis medidas com o Hidropletismômetro e comparadas com as medidas obtidas com o Deslocador de Água considerado "padrão ouro", através de provetas de vidro graduadas de 10 ml a 1000 ml. A confiabilidade intra e inter-examinadores foi realizada através do Coeficiente de Correlação Intraclasse (CCI) e a validade através do teste t pareado. O Coeficiente de Correlação de Pearson foi utilizado para estabelecer a associação entre os dois instrumentos. Os dados demonstraram níveis de confiabilidade intra e inter-examinadores com (CCI)3,1 = 0,99 e (CCI)3,2 = 0,99, respectivamente. Nenhuma diferença foi encontrada entre as medidas obtidas com o Hidropletismômetro e as obtidas com as provetas (p=0,404). A Correlação de Coeficiente de Pearson mostrou alta magnitute e nível de significância entre as medidas (r=1,0; p<0,0001). Os resultados evidenciaram que o Hidropletismômetro é um instrumento confiável e válido para medida de volume do tornozelo/pé.<br>Reliable and valid instruments are necessary to evaluate the effectiveness of the rehabilitation techniques.The objective this study was to evaluate the reliability and the validity of the water plethysmography. Fourteen subjects between the ages of 18 and 59 years were selected to participate in the study. Ankles were assessed by two trained examiners with the water plethysmography. Three measures of each ankle were obtained by the two investigators to evaluate intra- and inter-raters reliability. Twenty-six measures were obtained with the water plethysmography and compared with measurements obtained by graduated cylinders from 10 to 1000 ml, water displacement device (gold standart). Intraclass correlation coefficients (ICCs) evaluated intra- and inter-raters reliability, whereas paired Student t-tests and Pearson's correlation coefficients were used to establish validity of the water plethysmography.The results demonstrated excellent intra- and inter-rater reliability levels with levels with CCI3,1=0.99 and CCI3,2=0.99 respectively. No differences were found between the measures obtained with the water plethysmography compared to those of the water displacement device (p=0.40). Pearson's correlation coefficient showed a high magnitude and significance level between the measures (r=1,0; p<0.0001).The findings demonstrated that the water plethysmography is a reliable and valid instrument for measuring ankle/foot volume
