The space of merging submanifolds in R^n
Federico Cantero
Mathematics , 2014,
Abstract: We compute the homotopy type of the space of possibly empty proper $d$-dimensional submanifolds of R^n with a topology coming from a Hausdorff distance. Our methods give also a different proof of the Galatius--Randal-Williams theorem on the homotopy type of their space of submanifolds.
A note on hyperspaces and the compact-open topology
Federico Cantero
Mathematics , 2014,
Abstract: We prove that the inclusion of map(X,Y) into map(K(X),K(Y)) is continuous, where K(X) is the space of non-empty compact subsets of X (also known as the hyperspace of compact subsets of X), and both spaces of maps are endowed with the compact-open topology.
Origen étnico y cambios intergeneracionales en los niveles educacionales y sociales en la Araucanía
Williamson, Guillermo;Cantero, Violeta;
Cadernos de Pesquisa , 2010, DOI: 10.1590/S0100-15742010000100014
Abstract: this article refers to the inter-generational changes that have occurred in educational terms and by social category in three of the main communes of the araucária region of chile. it analyses the rates of educational mobility and the incidence of parent's education (educational capital) in the educational level of the children. it also provides evidence of the social and inter-generational transformation by ethnic origin that has occurred in this region, as well as of the greater occupational opportunities opened for individuals who have risen to higher levels of education. the study shows that even when educational inequality resulting from ethnic origin remained, higher education has created opportunities for social mobility for most those who had access to it.

Abstract: a retrospective case-control study was conducted aimed at knowing the perinatal results among the adolescents attended at “clodomira acosta ferrales”, in havana city, from january 1st, 1999 to march 31st, 2000. the study group (184 adolescents) was compared with a control group composed of pregnat women aged 20-24 (n = 439) that received attention in this center in the same period of time. gestational age, mode of delivery, weight and apgar score of the infant were some of the data collected by a survey done to this end. these data were processed by using the spss computerized statistical system. the results were showed in graphs. the most significant were the highest frequency of instrumental delivery and the asphyxial infants among the adolescents. it was concluded that in spite of the specialized care, early pregnancy is still a risk factor for obtaining unfavorable perinatal results.

Abstract: acute yellow hepatic atrophy present of pregnancy is an infrequent complication characterized by fatty liver infiltration provoking an acute hepatic failure and other not lesser severe complications, and its frequent association with pre-eclampsia, and similarity with other disorders, make difficult diagnosis and a delay in pregnancy completion, a behavior present when disorder is identified. authors made a matter review to increase our own knowledges and to improve diagnosis quality and management of pregnants with this severe complication.
Reproductive Behavior of Immigrant Latin American Women in Spain
Paula Acevedo Cantero
Social Medicine , 2008,
Abstract: The present study analyzes fertility patterns among a group of Latin-American female immigrants examining the impact of decade of birth, educational level, and migration on reproductive behavior. The study group was composed of 138 Latin-American women, aged 18 to 59 years, and residing in Spain. Menarche occurred at a mean age of 13.6 years old (sd 1.8) and the social initiation of fertility, as determined by age of first cohabitation, occurred at a mean age of 21.4 years (sd 0.4). Neither of these variables was affected by decade of birth. However, there were significant educational influences on age at first cohabitation. Women with a higher educational level showed delayed cohabitation and decreased fertility rates. On the other hand, there was in increase in the number of induced abortions after immigration to Spain seen among the youngest women. In conclusion, age at first cohabitation is an important indicator for the analysis of community demographic dynamics, although this age is conditioned by educational level. Likewise, adaptation to new social structures and situations is associated with changes in reproductive behaviors and may lead to practices among women that put their health at risk.

Abstract: Se realizó un estudio retrospectivo de caso control con el objetivo de conocer los resultados perinatales en las adolescentes atendidas en el Hospital "Clodomira Acosta Ferrales" de Ciudad Habana, del 1ro. de enero de 1999 al 31 de marzo de 2000. El grupo de estudio, 184 adolescentes, se comparó con un grupo control representado por las gestantes de 20 a 24 a os (n = 439) atendidas en dicho centro en igual periodo de tiempo. Datos referentes como edad gestacional, modo de parto y peso y Apgar del recién nacido, se recogieron en una encuesta habilitada al efecto y se procesaron utilizando el sistema estadístico computadorizado SPSS. Los resultados se exponen en gráficos,y los más relevantes fueron la mayor frecuencia del parto instrumentado y recién nacidos asfícticos entre las adolescentes. Se concluye que a pesar de la atención especializada, el embarazo precoz continúa siendo un factor de riesgo para obtener resultados perinatales desfavorables.

Revista Cubana de Obstetricia y Ginecolog?-a , 2009,
Abstract: La atrofia hepática amarilla aguda del embarazo es una complicación rara caracterizada por la infiltración grasa del hígado que provoca un fallo hepático agudo y otras complicaciones no menos graves. Su frecuente asociación con la preeclampsia y la similitud con otros trastornos dificultan el diagnóstico y retardan la terminación del embarazo, conducta indicada una vez identificado el trastorno. Se realizó una revisión del tema con el objetivo de aumentar nuestros conocimientos y mejorar la calidad del diagnóstico y manejo de las gestantes con tan severa complicación. Acute yellow hepatic atrophy present of pregnancy is an infrequent complication characterized by fatty liver infiltration provoking an acute hepatic failure and other not lesser severe complications, and its frequent association with pre-eclampsia, and similarity with other disorders, make difficult diagnosis and a delay in pregnancy completion, a behavior present when disorder is identified.
