School Schedules Affect Sleep Timing in Children and Contribute to Partial Sleep Deprivation     

Tâmile Stella Anacleto  Taísa Adamowicz  Laura Simões da Costa Pinto  Fernando Mazzilli Louzada 《Mind, Brain, and Education》2014,8(4):169-174

Although the environmental light/dark cycle is the main zeitgeber for the human species, the social cues seem to be important in the synchronization of circadian rhythms. In Brazil, the existence of two school schedules—one with only morning classes (MG) and other with only afternoon classes (AG)—allows the investigation of the effect of school activities on light exposure and sleep/wake patterns in children. Forty‐seven children wore wrist actimeters for a week for registration of light and sleep data. MG children presented shorter sleep duration on school days than the children from the AG. The results showed that during school days MG children were exposed to bright light earlier in the morning when compared to AG children. Nevertheless, there were no differences in light exposure after sunset. The results reflect the role of school schedules and artificial light in shaping light exposure, and its association with sleep timing in children.  相似文献   

Linguistic kernels for answer re-ranking in question answering systems     

Alessandro Moschitti  Silvia Quarteroni 《Information processing & management》2011

Answer selection is the most complex phase of a question answering (QA) system. To solve this task, typical approaches use unsupervised methods such as computing the similarity between query and answer, optionally exploiting advanced syntactic, semantic or logic representations.  相似文献

A Review of the Brazilian Book Market     

Ricardo Costa 《Publishing Research Quarterly》2011,27(1):72-75

Brazil is a huge country with at least 100 million readers with a total population of 200 million. Is this a good number for you? The article describes the developments of the Brazilian book market and publishing industry. Sales in 2009 were an estimated $2.5 billion for more than 228 million copies of books sold. But a country this big, as it is almost 50% of entire South America, confronts several major challenges including a real lack of bookstores. But one of the channels that is growing every year are the door-to-door sales, it has grown from 5% of all sales in 2006 to 17% in 2009. In a country this big, the digital or eBooks may also be a very good strategy to get to more readers, but it is still a small market in Brazil. The interesting news is that publishers are working on it and looking for solutions and ways to act on this new area of digital and online publishing.  相似文献   

Unsettling the ‘Challenge’: ELT Policy Ideology and the New Breach Amongst State-funded Schools in Colombia     

Norbella Miranda  Silvia Valencia Giraldo 《Changing English: An International Journal of English Teaching》2019,26(3):282-294

ABSTRACT

This article examines the ideologies present in Colombian official policy for English language teaching (ELT) and traces the links between governmental planning for state-funded schools and school pedagogical practices. Building on analysis of interviews with policy agents, policymakers’ pronouncements, documents and classroom observations, the article contends that instead of working towards educational equity, official policy actions are creating a new breach amongst state-funded schools, that is, between schools that are ‘focalised’ and others that are not. The national high-stakes exam for school leavers and the strategy of presenting policy goals and outcomes as a constant challenge perpetuate the knowledge-based economy ideology in the policy documents and pose a limit to teachers’ and schools’ decisions. The paper concludes with a call for a clear analysis of the material contexts of the ELT policy by policy actors at the macro-level and teacher agency that leads to student language learning despite policy constraints.  相似文献   

Children's Understanding of Agriculture as an economic activity: the role of figurative information     

Anna Maria Ajello  Anna Silvia Bombi  Clotilde Pontecorvo  Cristina Zucchermaglio 《European Journal of Psychology of Education - EJPE》1986,1(3):67-80

This paper presents the results of a curriculum of basic economic concepts given to 5 fourth-grade classes (Ss=95). The main topic of this curriculum was the production and distribution of agricultural produce, which had already proved to be difficult for the children. The proposed curriculum was largely inspired by the idea that familiarity with «social scenes» related to the economic process in question is necessary (although not sufficient) to allow children to understand such concepts. Children's level of understanding was tested before and after the curriculum by means of a semi-structured interview on 3 main topics: farmers' use of produce; farmers' use of earnings; produce distribution. Answers were scored according to their complexity and correctness; variance analyses performed on the scores showed significant improvements, as well as differences between classes. A qualitative analysis of children's answers was also performed, with the aim of interpreting the nature of change in each topic.  相似文献   

Caught in the triangle of mobility: social,residential and pupil mobility     

Bálint Ábel Bereményi  Silvia Carrasco 《British Journal of Sociology of Education》2018,39(1):32-46

This article examines the school choices of families who have recently experienced downward mobility during the economic crisis in Spain. Based on semi-structured interviews we analyse the educational strategies of the families in a Bourdieusian framework, focusing on how they cope with the loss of their perceived social status. Prior to the crisis, these families of working-class origin improved their social position as a result of their success in economic capital accumulation with a humble increase in social and cultural capital. Our research suggests that the concerns of families confronted with downward social mobility are manifested in tensions related to their school choice in terms of their strategies of resistance and negotiation with regards to the ownership, social composition and corresponding perceived quality of the school. School can symbolically represent the last resort, an indispensable investment in one’s own future and that of the next generation.  相似文献   

Alteration of serum beta 2-microglobulin in oral carcinoma     

C. R. Wilma Delphine Silvia  D. M. Vasudevan  K. Sudhakar Prabhu 《Indian journal of clinical biochemistry : IJCB》2002,17(2):104-107

Serum β₂-microglubin (β₂-m) levels were measured in oral carcinoma patients and compared with normal healthy controls. It was observed that there was a significant rise in serum β₂-microglobulin in oral carcinoma patients. Progressively higher values were obtained as the cancer advanced clinically. Therefore the estimation of serum β₂-microglobulin may be useful as one of a battery of tests in the assessment of oral carcinoma patients.  相似文献   

When differences do not matter: inclusion in a Mexican primary school / Cuando las diferencias no importan: la inclusión en una escuela primaria mexicana     

Maribel Cruz-Ortiz  Cristina Jenaro-Río  Dora-Esperanza Sevilla-Santo  Silvia Cruz-Ortiz 《Cultura y Educación》2016,28(1):72-98

Studies show that disability is a cause of educational exclusion worldwide. Different countries adopt different views of the inclusion movement. Different variables seem to be associated with the success or failure of inclusion. This study takes place in a primary school located in Mexico. It aims to identify how inclusion is experienced by children with and without special needs, and the connections between inclusion and quality of life. Measures utilized were the questionnaire My Primary School from the Index for Inclusion and the Questionnaires on Assessment of Quality of Life for Children, self-report, and parents’ report. Participants are 69 regular students and 15 students with special education needs. Self-reports from regular children and proxy reports from the mothers of the special education needs students were analysed. Results indicated that there is an association between perceived inclusion and experiencing quality of life; having special needs does not impact on scores on QoL or inclusion; educational level does not impact on perceived QoL or inclusion for special education students. These results are discussed in light of a culture that appreciates diversity.  相似文献   

Student satisfaction in higher education: a meta-analytic study     

Fernando de Oliveira Santini  Wagner Junior Ladeira  Claudio Hoffmann Sampaio  Gustavo da Silva Costa 《Journal of Marketing for HIGHER EDUCATION》2017,27(1):1-18

This paper discusses the results of a meta-analysis performed to identify key antecedent and consequent constructs of satisfaction in higher education. We offer an integrated model to achieve a better understanding of satisfaction in the context of higher education. To accomplish this objective, we identified 83 studies that were valid and relevant to the research objective of the current study, generating a total of 469 observations. We identified studies published from 1986 to 2016 and analyzed six antecedent dimensions (perceived value of educational services, resources provided to the student, service quality perception, marketing orientation, identity of the higher education institution, university environment) and one consequent dimension related to satisfaction. The 7 dimensions exhibited a total of 51 relationships. We believe that the originality of the findings clearly contributes to future academic research in higher education.  相似文献
