Jorge R. Sanchez  Frankie Santos Laanan  W. Charles Wiseley 《Research in higher education》1999,40(1):87-113

In the wake of new federal and state mandates,community colleges are faced with demands to provideaccountability reports on student outcomes. With the useof the Employment Development Department Unemployment Insurance (EDD-UI) wage record data, along withthe California Community Colleges Chancellor's OfficeManagement Information System administrative database,this study sought to investigate the extent to which completing an associate degree andvocational certificate impacts the postcollege earningsof students. Based on information from 700,564 studentsfrom California community colleges during the 1992-93 academic year, the findings suggest thatstudents' gains from first year out of college to thirdyear out will differ by age group. Among economicallydisadvantaged students, a strong positive relationship exists between educational attainment andpostcollege gains. An important finding among vocationalstudents is that as women complete more education, theearnings gap closes between men and women. Finally, this study raises several policy implicationsand presents suggestions for future research.  相似文献   

Carnation Atoms? A History of Nuclear Energy in Portugal     

Tiago Santos Pereira  Paulo F. C. Fonseca  António Carvalho 《Minerva》2018,56(4):505-528

Drawing upon the concepts of civic epistemologies and sociotechnical imaginaries, this article delves into the history of nuclear energy in Portugal, analyzing the ways in which the nuclear endeavor was differently enacted by various sociopolitical collectives – the Fascist State, post-revolutionary governments and the public. Following the 1974 revolution - known as the Carnation Revolution - this paper analyzes how the nuclear project was fiercely contested by a vibrant anti-nuclear movement assembled against the construction of the Ferrel Nuclear Plant, the first sociotechnical controversy in Portugal, paving the way for the emergence of a combative civic epistemology. Supported by semi-structured interviews with scientists, activists and local residents of Ferrel and the analysis of historical material, this article presents the failed Portuguese nuclear endeavor as an emblematic case study to explore the co-production of science and society, in particular the role of revolutionary processes in the unfolding of sociotechnical controversies.  相似文献   

The fatigue effect of a simulated futsal match protocol on sprint performance and kinematics of the lower limbs     

Juliano Dal Pupo  Daniele Detanico  Jonathan Ache-Dias  Saray Giovana dos Santos 《Journal of sports sciences》2017,35(1):81-88

This study aimed to investigate the fatigue effects induced by a futsal-specific protocol (FIRP) on sprint performance and the kinematics of the lower limbs. Twenty-one futsal players participated in this study and performed a protocol to simulate the futsal demands. At pre-protocol, half-time and post-protocol, the athletes performed 10-m sprints that were recorded for kinematic analysis. Continuous relative phase (CRP) was calculated to assess the inter-segmental coordination. In addition, vertical (K_VERT) and leg (K_LEG) stiffness were calculated. Analysis of variance (ANOVA) for repeated measures was used (P < 0.05). The main results showed that sprint time increased (P < 0.01) post-protocol when compared to pre- and half-time conditions. Lower values of the step rate (P = 0.01) and higher values of the leg angular velocity (P = 0.02) were verified at the end of the FIRP. The CRP of thigh–leg and leg–foot and the stiffness did not change over the protocol. In addition, the high correlation of CRP between the conditions revealed no changes in coordination pattern. We concluded that futsal related-fatigue induced a decrement on sprint time, changing the kinematics of the lower limbs (decreasing step rate and increasing leg angular velocity). However, neither stiffness nor intersegment coordination during sprints was affected by fatigue.  相似文献   

Playing outdoor and practising sport: A study of physical activity levels in Portuguese children     

Paula Silva  Maria Paula Santos 《European Journal of Sport Science》2017,17(2):208-214

In outdoor activities, it seems reasonable that the longer children spend in spontaneous physical activity (PA), the higher the probability of being active. Indeed, the time spent outdoor has been identified as a variable consistently associated with the children’s PA. Outdoor playing, such as the organized sports practice, appears associated with healthier lifestyle standards. All the recommendations mention the importance of increasing daily PA practice in children and teenagers, but few studies highlight the relationship between outdoor play and the recommended PA levels. The purpose of this study is to investigate the relationships between the frequency of outdoor play, the frequency of the organized sports practice, and the compliance of the recommendations for PA practice in children in the inner city area of Porto. The sample of this study is composed of 422 individuals (mean age of 11.6 years). Two hundred and twenty-five of them were girls and 197 were boys from the sixth grade (elementary schools located in the inner city area of Porto). PA was objectively evaluated using accelerometers. Participants reported frequency of participation in different PA contexts, such as sports practice and outdoor play. The results show a predictor effect of participating in sports three or more times per week on compliance of PA guidelines.

In conclusion, organized sports practice seems more effective than outdoor play to reach the recommended levels of PA in children.  相似文献   

Horizontal ground reaction forces to stationary running performed in the water and on dry land at different physiological intensities     

Cristine Lima Alberton  Stephanie Santana Pinto  Gabriela Neves Nunes  Douglas Guerreiro dos Santos Rau  Paula Finatto  Amanda Haberland Antunes 《European Journal of Sport Science》2017,17(8):1013-1020

The aim of the present study was to compare the peak anterior–posterior (Fy) and medio–lateral (Fx) ground reaction forces (GRFs) of women performing stationary running at different intensities in aquatic and dry land environments. Fourteen young women performed the stationary running exercise at three cadences (first ventilatory threshold, second ventilatory threshold and maximum effort, as determined during exercise in water) in aquatic and dry land environments. Two-way repeated measures ANOVA was used to analyse the data (α?=?.05). As a result, significantly lower peak Fy anterior, Fy posterior, Fx medial and Fx lateral values were observed for the aquatic environment, except for the Fy posterior at the first ventilatory threshold. Significant differences were observed between cadences in the peak Fy anterior, Fy posterior, Fx medial and Fx lateral values, with higher values for the cadence corresponding to maximum effort compared to the first ventilatory threshold, except for the Fy posterior and Fx medial in the aquatic environment. The results indicate that the horizontal GRFs are reduced in the aquatic environment and depend on the intensity of stationary running exercise performance.  相似文献

Ethics in educational technology research: Informing participants on data sharing risks     

Marc Beardsley  Patricia Santos  Davinia Hernández-Leo  Konstantinos Michos 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(3):1019-1034

Participants in educational technology research regularly share personal data which carries with it risks. Informing participants of these data sharing risks is often only done so through text contained within a consent form. However, conceptualizations of data sharing risks and knowledge of responsible data management practices among teachers and learners may be impoverished—limiting the effectiveness of a consent form in communicating such risks in a manner that adequately supports participants in making informed decisions about sharing their data. At two high schools participating in an educational research project involving the use of technology in the classroom, we investigate teacher and student conceptions of data sharing risks and knowledge of responsible data management practices; and introduce a communication approach that attempts to better inform educational technology research participants of such risks. Results of this study suggest that most teachers have not received formal training related to responsibly managing data; and both teachers and students see the need for such training as they come to realize that their understanding of responsible data management is underdeveloped. Thus, efforts beyond solely explaining data sharing risks in an informed consent form may be needed in educational technology research to facilitate ethical self-determination.  相似文献   

English language learning difficulty of korean students in a Philippine Multidisciplinary University     

Allan B. de Guzman  Emmanuel Jeric A. Albela  Deborah Rosalind D. Nieto  John Bernard F. Ferrer  Rior N. Santos 《Asia Pacific Education Review》2006,7(2):152-161

This qualitative study analyzed the English language learning difficulties of 13 purposively chosen Korean students relative to their sociolinguistic competence, motivation in using the English language, and cultural factors. Interview responses were transcribed, categorized and thematised according to saliency, meaning and homogeneity. The findings of the study disclosed that, on the whole, while the subjects never had the opportunity to use the English language in Korea, they use it almost everywhere in the Philippines. Their difficulties exist both in daily conversation and in the academic setting. Such difficulties are attributable to both the subjects’ and the Filipinos’ different entry points in the learning and use of English. Despite cultural barriers in communication, however, the Koreans studying in the Philippines are instrumentally motivated to learn the English language.  相似文献   

Role of the Undergraduate Student Research Assistant in the New Millennium   总被引：1，自引：0，他引：1  

Thais Dutra Nascimento Silva  Lúcia Cristina da Cunha Aguiar  Jaqueline Leta  Dilvani Oliveira Santos  Fernanda Serpa Cardoso  Lúcio Mendes Cabral  Carlos Rangel Rodrigues    Helena Carla Castro 《CBE life sciences education》2004,3(4):235-240

In this study, we analyze the contribution of the undergraduate student who participates in the process of generating scientific data and developing a research project using Brazilian research as an example. Historically, undergraduate students have performed the critical role of research assistants in developing countries. This aspect has been underappreciated as a means of generating scientific data in Brazilian research facilities. Brazilian educational institutions are facing major age-related generational changes among the science faculty within the next 5–10 yr. A lack of adequate support for graduate students leads to a concern that undergraduates will not be interested in choosing research assistant programs and, subsequently, academic research careers. To remedy this situation it is important to focus on ways to encourage new research careers and enhance university–industry collaborations.  相似文献   

The pathways to higher education: lexical availability in adult candidate students and in young first-year students     

Luís Filipe Barbeiro  Cláudia João  Susana Santos 《International Journal of Lifelong Education》2013,32(3):309-329

In the past few years there has been an increase in the number of adult students in higher education courses, many of whom have returned to school after a break. Most of these students do not intend to continue their studies from the point where they stopped; rather, they want to prepare for specific tests in order to have direct access to higher education courses, which in Portugal is a legal option for students over the age of 23. In response to this new cohort, higher education institutions need to find out what kind of students these are, determining their characteristics, capabilities and major problems, if they are to provide them with successful learning opportunities alongside younger students. This article presents a comparative study of lexical competence, focusing on lexical availability, contrasting those adult applicants to higher education who are attending a course preparatory to higher education with first-year students who have just entered higher education. The results show significant differences between the two groups, the adult group in general showing poorer results. Their withdrawal from schooling is clearly reflected in their vocabulary activation with regard to transversal themes. The most salient contrasts are related to the number of words mentioned and the frequency of words in the group, as well as the greater or lesser proximity to the topic of the terms mentioned.  相似文献
