Abstract Since 1947, distance education in Mexico has had an important role for nonconventional populations. Considering that distance education is a heterogeneous and dynamic field, it is important to reflect on the need to improve quality as measured by our own standards. With that perspective in mind, a national meeting was organized to start a self‐diagnosis in which quality and access were the main concerns. Five hundred and twenty specialists from fifty‐one institutions participated in a national interactive synchronous meeting held in four regions. As a result of the meeting, thirty‐five criteria and 230 parameters of quality were established. The main conclusion of the meeting refers to the need for the elaboration of our own indicators for open and distance education. 相似文献

In this study we aim at learning about adolescents’ future fears and wishes from different cultural origins with a view to finding implications for intervention in the furthering of their satisfaction and social integration in their acculturation process. The study sample comprised 938 secondary school students—64.4% Spanish, 19.7% South American and 12.8% African. Wishes and fears were evaluated by means of two open questions and the answers were categorized following traditional content analysis methodology. Results show that the adolescents wish for a satisfactory job, family and economic situation, and that they are concerned about aspects such as their own health and that of their family, the possibility of having a precarious job, isolation from their family of origin, and not forming a family. The findings also allow us to give differential profiles according to the cultural origin of the adolescents. 相似文献

SYNOPSIS Objective . To explore whether maternal sensitivity is associated with Autism Spectrum Disorder (ASD) severity in children with and without ASD. Design . The samples consisted of 25 Mexican dyads of children with ASD (aged 3.1-6.9 years) and their mothers (aged 20-47 years) and 24 Mexican dyads of children without ASD (aged 3.4-6.7 years) and their mothers (aged 24-45 years). Maternal sensitivity and ASD severity symptoms were scored from 2-h videos of mother-child daily interactions. Results . A between-group comparison showed a trend toward less severe ASD in children with highly sensitive mothers, specifically in the Nonverbal Communication subdomain. Conclusions . Greater maternal sensitivity is associated with improved social ability in children with ASD. 相似文献

Thirty‐eight Latin American mothers with young children tell of their perceptions of school discipline and comportment issues and talk of their children's encounters with ‘zero tolerance’ legislation, and related rules for conduct, implemented by the local school boards. The purpose of this exploratory study is to understand: (a) parents' views of and concern about disciplinary practices at school; (b) parents' ideas about the connection between home and school discipline; and (c) parents' understanding of the officially prescribed consequences of behaviour identified as non‐tolerable. Implications of the findings are discussed with regard to professional practice. 相似文献

The PI control configuration for stabilization and signal tracking of nonlinear systems is investigated. Semiglobal asymptotic stability and semiglobal practical signal tracking of the controlled system are proven using results from the theory of nonlinear singularly perturbed systems. 相似文献

This study aimed to analyse the effects of a simulated Brazilian jiu-jitsu (BJJ) tournament on vertical jump performance, grip strength test and perceived effort responses. 22 male BJJ athletes participated in a simulated tournament consisting of three 7 min matches separated by 14 min of rest. Kimono grip strength test (KGST), counter movement jump (CMJ) and rate of perceived exertion (RPE) were measured before and after each match, while RPE of specific areas was assessed after three matches. ANOVA for repeated measures was used to compare strength parameters after each match with the level of significance set at 5%. The key results showed a significant decrease of jump height (p = 0.001) and net vertical impulse in the CMJ (p = 0.031), as well as a reduction of the number of reps in the KGST (p < 0.001). A significant increase of RPE was found throughout the matches (p < 0.001). Considering the RPE in specific areas, no differences were observed between the upper and lower body (p = 0.743). We conclude that the BJJ simulated tournament generated a decrease of performance in both upper and lower limbs and provoked a progressive increase in the effort perception over the matches. 相似文献

The southernmost area of Texas, known as the Rio Grande Valley, is largely absent from histories of early radio. The social, political, and economic history of the Valley from 1848 to the 1950s prompts the authors to approach the region’s broadcast history from the context of rural and farm radio. The papers of broadcaster Bradford Smith, housed at the Margaret H. McAllen Memorial Archives at the Museum of South Texas History, provide an entryway for Valley radio to become part of the larger body of rural and farm radio scholarship. Smith’s radio reports emphasize the centrality of localism for remote communities, and they provide competing narratives about the region’s modern identity and its Mexican roots. 相似文献

Exploring the micromotivations (Williams, 1979, 1988; Aguiar, 1991)or internal reasons (Williams, 1979; Lupia, McCubbins, & Popkin, 2000)that mold public preferences for either democracy or authoritarianism,this paper aims to discuss the types of rationality that liebehind people’s choices in survey studies in Latin America.From this perspective, we examine the balance between surveyrespondents’ evaluation of democratic government and theirviews of the efficacy of democracy to solve their country’sproblems, and their joint impact on the molding of citizens’preferences for a particular type of government. Results showthat satisfaction with how democratic government performs standsout as one of the reasons underlying individuals’ preferencesfor democracy. Also the belief that democracy does not solvethe problems significantly determines the people’s choice.Conclusions favor the hypothesis that, in the region, a utilitarianrationality prevails over an axiological rationality (Weber, 1922;Boudon, 1996) in the way citizens form preferences for or againstdemocracy. 相似文献
