Choices and Motivations: the why and how of Portuguese students' enrolment choices     

Orlanda Tavares  José Brites Ferreira 《European Journal of Education》2012,47(2):310-326

The student population is becoming increasingly diversified and heterogeneous. In a climate of decreasing traditional enrolments in the Portuguese higher education system and increasing competition for students, it becomes essential to understand the reasons and motivations that attract students to higher education and which are the more relevant factors they consider when choosing a higher education institution. This article presents the preliminary analysis of the results of a questionnaire filled in by a sample of 11,467 students entering different types of higher education institutions in 2006/07.  相似文献   

Cognitive processes and math performance: a study with children at third grade of basic education     

Isabel S. Campos  Leandro S. Almeida  Aristides I. Ferreira  Luis F. Martinez  Glória Ramalho 《European Journal of Psychology of Education - EJPE》2013,28(2):421-436

The present study aims to examine the relationship between cognitive factors and mathematical achievement in primary education. Participants were 103 Portuguese third grade students, aged 8 and 9. All participants completed a battery for working memory (WMTB-C), a test of general intelligence (Raven's Progressive Color Matrices), a selective attention test (d2), and mathematical exercises (arithmetic story problems and measurement skills). Data suggested significant correlations between math performance, executive, visuospatial sketchpad and g factor. Our findings suggest the importance of the cognitive factors in two mathematical domains considered. In consonance with the research in this area, we conclude that working memory (WM) assumes an important role in different math curricular achievements.  相似文献   

Aerobic exercise training performed by parents reduces mice offspring adiposity

The present study aimed to determine the effects of physical training performed by parents on mice offspring adiposity. Male and female parents underwent an aerobic training protocol for 7 weeks. The trained and sedentary parents were allowed to mate and the resultant offspring divided in: S (Offspring from Sedentary Parents), T (Offspring from Trained Parents), ST (Offspring from Sedentary Father and Trained Mother) and TS (Offspring from Trained Father and Sedentary Mother). After weaning, offspring was euthanized, blood collected and samples of mesenteric and inguinal fat pads used to isolate adipocytes for morphologic and histological analyses. Lee index, mesenteric fat pad, sum of visceral fat and total fat weight of female T was reduced in comparison to the other groups (p < 0.05). Periepididymal and sum of visceral fat in male T group was also reduced when compared to the other groups (p < 0.05). The diameter of mesenteric and inguinal adipocytes of T group was smaller compared to all groups comparisons for both sexes (p < 0.05). In summary, exercise training performed by parents reduced visceral offspring adiposity, the diameter of subcutaneous adipocytes and improved metabolic parameters associated to metabolic syndrome.  相似文献   

Effect of a pilot multi-component intervention on motor performance and metabolic risks in overweight/obese youth     

Dominique Silva Silveira  Luis Filipe Gomes Barbosa Ferreira Lemos  Rafael Miranda Tassitano  Maria Teresa Cattuzzo  Anderson Henry Pereira Feitoza  Luisa Maria Seara Moreira Carneiro Aires 《Journal of sports sciences》2018,36(20):2317-2326

This study evaluated the effect of a multi-component intervention on motor performance (MP) and metabolic risk markers (MRM) in overweight/obese youth. A secondary aim was to examine whether changes in MP are associated to changes in MRM. A 3-month multi-component intervention was performed, consisting of physical exercise sessions (twice/week;1h), nutritional education sessions (once/month), and parental support (twice/week). The sample included 35 volunteers (7–13 y.o), allocated to intervention (INT, n = 17) and control (CONT, n = 18) group. Variables were measured pre (T0) and post intervention (T1). Fasting blood samples were analyzed for MRM. MP tests included the measurement of health related physical fitness components and motor coordination performance (KTK battery). To assess food intake, a 24-hour recall diary was used. GLM-ANCOVA was performed. Standardized scores were calculated for the outcome variables, and multilinear regressions were applied to analyze associations between the key variables. INT group showed improvements in MP, glycolytic and hepatic profiles. After adjustments for MVPA, SB, total intake and maturational stage, negative associations between %ΔMP and %Δglycolytic (β = -.424; 95%CI:-0.343:-0.022), and %Δhepatic scores (β = -.382 95%CI:-0.001:-0.009) were observed. The intervention produced a moderate-to-high effect on the MP and some MRM. Changes in MP were inversely associated with changes in glycolytic and hepatic markers.  相似文献   

Performance evaluation of the high sensitive troponin I assay on the Atellica IM analyser

IntroductionThe Fourth Universal Definition of Myocardial Infarction Global Taskforce recommends the use of high sensitive troponin (hs-Tn) assays in the diagnosis of acute myocardial infarction. We evaluated the analytical performance of the Atellica IM High-sensitivity Troponin I Assay (hs-TnI) (Siemens Healthcare Diagnostics Inc., Tarrytown, USA) and compared its performance to other hs-TnI assays (Siemens Advia Centaur, Dimension Vista, Dimension EXL, and Abbott Architect (Wiesbaden, Germany)) at one or more sites across Europe.Materials and methodsPrecision, detection limit, linearity, method comparison, and interference studies were performed according to Clinical and Laboratory Standards Institute protocols. Values in 40 healthy individuals were compared to the manufacturer’s cut-offs. Sample turnaround time (TAT) was examined.ResultsImprecision repeatability CVs were 1.1–4.7% and within-lab imprecision were 1.8–7.6% (10.0–25,000 ng/L). The limit of blank (LoB), detection (LoD), and quantitation (LoQ) aligned with the manufacturer’s values of 0.5 ng/L, 1.6 ng/L, and 2.5 ng/L, respectively. Passing-Bablok regression demonstrated good correlations between Atellica IM analyser with other systems; some minor deviations were observed. All results in healthy volunteers fell below the 99th percentile URL, and greater than 50% of each sex demonstrated values above the LoD. No interference was observed for biotin (≤ 1500 µg/L), but a slight bias at 5.0 g/L haemoglobin and 50 ng/L Tn was observed. TAT from was fast (mean time = 10.9 minutes) and reproducible (6%CV).ConclusionsReal-world analytical and TAT performance of the hs-TnI assay on the Atellica IM analyser make this assay fit for routine use in clinical laboratories.  相似文献

Developing and sustaining an educative mentoring model of STEM teacher professional development through collaborative partnership     

Gail Richmond  R. Charles Dershimer  Maria Ferreira  Nelson Maylone  Beth Kubitskey  Alycia Meriweather 《Mentoring & Tutoring: Partnership in Learning》2017,25(1):5-26

In this paper, we present details of a partnership undertaken by four universities with field-based, alternative STEM teacher preparation programs and a large urban school district to provide ongoing professional support for teachers serving as mentors for individuals preparing for careers in high-poverty schools. We also present key findings related to our implementation of an educative mentoring professional learning community (PLC) as a professional development (PD) model for these mentors. Our analysis reveals that mentors as well as candidates identified the PD program as addressing their specific interests and concerns, and that they were regularly and deeply engaged with key activities that were part of each session’s agenda. These findings signal how key elements of PD workshops can contribute to creating and sustaining a local but replicable PLC utilizing an educative mentoring model to support mentors and the future teachers whom they support.  相似文献

ABSTRACT

This paper intends to present an interdisciplinary project carried out in a School of Engineering, and to refer to its effects in the development of students’ skills. This project’s main goal was to present students with an intellectually demanding challenge which implied overcoming the disciplinary barriers thus integrating knowledge to solve the problems they were challenged with. After the project had been concluded, a study was carried out using a qualitative methodology by conducting two focus groups (n?=?16). The main goal of this procedure was to get a better perception of (1) how students understood the project; (2) what kind of skills students considered to have developed throughout the project, and (3) the importance they have attributed to this kind of project. The results demonstrate that students are aware of the relevance of the project not only for their education process but also for the development of their skills. The results of the study also reveal that the students involved in the project have been capable of identifying the specific skills that the project work had intended to address and develop.  相似文献

Key points

• Instructions to authors about submitting papers for publication vary hugely – from none at all to whole handbooks.
• Online submission systems have not reduced the complexity of submission and may have increased the work of authors.
• Electronic submission processes do not appear to have been adequately ‘road tested’ with authors.
• Some publishers are introducing more flexible submission rules that may help authors.
