Association of Elevated Serum Lipoprotein(a), Inflammation,Oxidative Stress and Chronic Kidney Disease with Hypertension in Non-diabetes Hypertensive Patients

Hypertension is the most common cardiovascular risk factor. Lipoprotein(a) [Lp(a)], inflammation, oxidative stress and chronic kidney disease (CKD) exacerbate the response to tissue injury and acts as markers of the vascular disease, especially in glomerulosclerosis. We compared the clinical characteristics of 138 non-diabetes hypertensive women (ndHT) patients with 417 non-diabetes normotensive subjects and tested the association of hypertension with Lp(a), inflammation, CKD and oxidative stress by using multiple logistic regression. BP, BMI, waist circumference, creatinine, Lp(a), inflammation and malondialdehyde levels were significantly higher and CKD state in the ndHT patients (p < 0.05). Multiple logistic regression showed hypertension associated with increased Lp(a), inflammation, ORs and 95 % CIs were 2.52 (1.33, 4.80), 2.75 (1.44, 5.27) after adjusting for their covariates. Elevated serum Lp(a) and inflammation levels concomitants with increased oxidative stress and CKD were the major risk factors associated with hypertension and implications for the increased risk of HT and vascular disease.

Critical factors influencing secondary school pupil’s decisions to study computing in tertiary education: Gender differences

This paper aims to determine the factors affecting the decisions of both male and female secondary school pupils whether or not to pursue undergraduate studies in Computing. It is based on research conducted in Greece, on a sample of 248 pupils, 135 of whom were female. All were aged 17 and about to decide on their future undergraduate studies. Questionnaires were used, addressing issues in the following four main categories: a) the reasons pupils chose/rejected Computing, b) how family and friends, the media and the school environment contribute to their decision, c) how pupils perceived their future after studying Computing and d) how pupils perceived the profile of a computer professional in terms of gender.

Locus and nature of perceptual phonological deficit in Spanish children with reading disabilities

The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit.     

Getting sloshed in outer space

We document some basic facts about how liquids behave in the low gravity of outer space and how this poses challenges to space scientists and engineers who need to design and test systems that handle fluids in outer space while working in the 1-g environment on Earth.

中德高职教育与企业关系的理性分析

德国企业在"双元制"高等职业教育中发挥举足轻重的作用。由于我国高职教育制度不完善,导致企业对高等职业教育参与度比较低,借鉴德国企业深度参与高等职业教育的先进经验和管理模式,我们应准确定位企业与高职教育关系,推进高职教育办学体制多元化改革;建立健全企业参与高职教育的激励机制,使高职教育发展由学校本位向企业主导转变;进一步提升企业责任和人才竞争力意识,形成互动双赢的校企合作机制。     

“可能”、“会”的“或然性”高低及特点

“可能”、“会”都可表示估计将成事实与否,但其“或然性”并不相等。“会”表推测性肯定,而“可能”只是个表肯定性不强的词语,因此就其所反映的“或然性”性质而言,“会”是个点,其值为“1”,而“可能”是个弹性区间,其值徘徊在“0．5”左右。     

Evaluation and publication delay in Ibero-American scientific journals

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.     

日本国家级教育政策研究机构的改革与职能定位——基于日本国立教育政策研究所的分析

日本的国家级教育政策研究机构包括国家级政府主导的公务机关性质的教育政策研究机构、独立行政法人性质的教育政策研究机构和大学或大学附属性质的教育政策研究机构。为了更有助于国家层面教育政策的整体规划和深度推进,日本文部科学省对原有的国家级教育政策研究机构进行了改革重组,强化了其服务于政府宏观教育决策的职能。以代表日本国家级教育政策研究机构的国立教育政策研究所为例,改革后其职能为:准确恰当并且迅速地应对教育行政上的诸多课题;回应教育基层实践的要求,进行全面综合地调查研究;向教育相关者提供教育研究情报信息;开展教育领域的国际性的共同研究;推进与地方政府的教育研究所或研究中心等的共同研究。日本国家级教育政策研究机构的改革与发展,为我国教育政策研究的科学化发展提供了参考和启示。
