The Subtle Colourings of （Informed） Consent in Performance Enhancement： Implications for Expertise

Journal of Philosophy Study 2017年第4期7卷 197-203页

作者： konstantinos G. papageorgiou University of Athens

The analytic method, part of the epistemonic method, provides us with a way to cope with perplexed cases, without even referring to the world out there. We are able to predict all possible variations of consent, and go on forming minimum logical quadripoles, 8-poles, 16-poles, etc., before even trying to make any connection to the world. This way, there are two major outcomes： All possible scenarios are predicted, and, because of that, our ＂logical generator＂ produces scenarios we couldn＇t even think of. Consent is, therefore, neither binary （existence or absence）, nor just a continuum from existence to absence, but a cladistic tree stemming from the basic quadripole ＂existence of consent/not existence of consent/absence of consent/not absence of consent.＂ The complexity increases rapidly when other terms are included; try：＂existence of informed consent＂ or ＂existence of unintentional consent.＂ More levels develop as we examine relevant terms, such as ＂exposure,＂＂protection,＂ or ＂consumption.＂ In our case-study, we shall examine how different aspects of consent are expressed regarding the issue of performance enhancement and consider some implications for the notion of expertise within an SEA （Science of Exceptional Achievement） context. Many different terms may describe the most common situations, namely, ＂uniformed consent,＂＂unintentional consent,＂＂non-intentional consent,＂＂not absence of consent,＂ and also, ＂unintentional exposure,＂＂intentional non-protection,＂ and so on. In Greek language, the possible variations are even more （there are two kinds of negation in Greek）. All the aforementioned terms have different ethical consequences. We shall also examine whether doping is an inherent part of expertise attainment.

目的:讨论孕妇Valsalva视网膜病变保守或手术治疗方法的选择。方法:一健康孕妇在自然阴道分娩时,右眼底发生黄斑前玻璃体后界膜下出血,本文报道其保守治疗的效果。结果:右眼发病3wk时积血收缩,视力为眼前手动,但病程6mo时,积血溶解,视力恢复至6/5。结论:大多数Valsalva视网膜病变能够自愈。对一些难治性病例,采用Nd:YAG激光行内界膜切开具有一定的效果。而早期玻璃体切除术的增殖膜切除,对预防眼底新生血管膜的发生也具有一定的效果。

Is there sufficient evidence to support the use of antibiotic holiday just before the second stage of an infected total hip or knee arthroplasty revision surgery?

The practice of implementing an antibiotic holiday before the second stage of hip or knee arthroplasty is currently controversial due to limited evidence for this approach,as per the International Consensus Meeting 2018 on Musculoskeletal Infection.A greater understanding of this issue could augment the quality of Alrayes and Sukeik’s mini-review(2023)on diagnosing,managing,and treating periprosthetic knee ***,a significant lack of literature exists concerning the optimal duration for the antibiotic holiday,calling for more research before establishing any clinical guidelines.

Evaluation of Technical Education by Using a Modern Structured MOODLE Laboratory Course, in Relation to Recent Data

引用

Journal of Intelligent Learning Systems and Applications 2024年第3期16卷 316-339页

作者： Gerasimos Vlassopoulos George Albert Karikas Efstathia papageorgiou Ioannis Psaromiligkos Niki Giannouli Pigi Vlassopoulou Petros Karkalousos Department of Biomedical Sciences University of West Attica Athens Greece

E-learning platforms support education systems worldwide, transferring theoretical knowledge as well as soft skills. In the present study high-school pupils’, and adult students’ opinions were evaluated through a modern structured MOODLE interactive course, designed for the needs of the laboratory course “Automotive Systems”. The study concerns Greek secondary vocational education pupils aged 18 and vocational training adult students aged 20 to 50 years. The multistage, equal size simple random cluster sample was used as a sampling method. Pupils and adult students of each cluster completed structured 10-question questionnaires both before and after attending the course. A total of 120 questionnaires were collected. In general, our findings disclosed that the majority of pupils and adult students had significantly improved their knowledge and skills from using MOODLE. They reported strengthening conventional teaching, using the new MOODLE technology. The satisfaction indices improved quite, with the differences in their mean values being statistically significant.

央行数字货币(CBDC)快速发展,与传统法定货币不同,CBDC对宏观经济,尤其是对邻国的宏观经济有哪些影响值得关注。本文建立了一个考虑内生货币替代和金融摩擦的两国新凯恩斯模型,以考察大型外国经济体发行的稳定币对小型发展中经济体的影响。研究发现,外国稳定币为国内经济中的家庭提供流动性服务,并为国内通胀提供额外的对冲;同时,它的引入放大了货币替代效应,减少了银行中介作用,削弱了货币政策传导作用,加剧了衰退冲击的影响,增加了银行业经营压力;而资本管制提高了稳定币作为规避手段的使用率,增加了对外国冲击溢出效应的敞口。与国内中央银行数字货币不同,禁止外国稳定币支付可以缓解这些影响。本刊编译此篇国际货币基金组织(IMF)的工作论文,以期为读者带来启示。
