浪漫派画家德拉克罗瓦

法国画家费迪南·维克托·欧仁·德拉克罗瓦(1798—1863)屏弃了新古典主义风格,以热烈的色彩,开拓出一种更为自由、更富浪漫气息的画风。     

呼吸和代谢的变异性:对次最大强度自行车和跑步运动的反应

次最大吸氧量、通气量和血乳酸常被用来评定体质、训练效果和治疗效果。研究人员通常都假定这些变量在不同的日子里是稳定的,而不考虑受试者和仪器所造成的日常变化(Faulkner1971)。本研究的目的就是想检验这一假设以及用数量来表示受试者、仪器等的日常变异性。在连续几天里利用交叉设计测定有经验的自行车、跑步运动员在次最大强度自行车和跑台试验中的吸氧量、每分通气量和血乳酸。方法在8—9天内对10名健康男性受试者(5名自行车运动和5名跑步运动员)随机进行四次自行车功率计试验和四次跑台试验。受试者在身体特征上没有显著差异。自行车运     

学前儿童创造性的非正式评价

研究幼儿的创造性必然涉及评价问題。正式的评价方法很复杂,需要特殊的设备和量表,必须由专业人员操作。这儿介绍一种非正式评价方法,供读者鉴定创造型英才儿童和创造倾向行为时参考。这方法是为教育学界和心理学界广泛接受的。     

电刺激在肌肉静力训练中的应用

苏联的研究者近年建议用电刺激来训练运动的肌肉静力力量。电刺激的原理是由电引起肌肉有次序地反复收缩,可用直接法和间接法使肌肉作这样的收缩。直接是把电极安放在躯干或远离躯干需要进行训练的肌肉之上;而间接法则是对某些运动神经进行刺激。为此目的,阿德莉安诺娃及其助手发明了一种训练肌肉的电刺激法,该法使用频率为2500赫兹的调制交流电。相对平时使用的使肌肉紧张的各种办法而言,电刺激具有以下优点: ——“电训练”可使收缩的肌肉最大     

格拉斯梅——华滋华斯的故乡

如今,已经没有人“象飘浮的云彩一般”,在华滋华斯故乡的村中独自徘徊了。每年,数以万计的仰慕华滋华斯盛名的人群来到他的墓前凭吊,追念这位将湖区精华尽收笔下的诗人。     

运动员训练程度综合评定法

在全年训练周期中的每个具体阶段,对运动员训练程度如何评定,是运动训练的一个重要问题。客观地评定运动员的训练状况和及时掌握它的动态,是有效地控制未来训练进程的必要条件。通常认为,运动成绩就是运动员训练状况的标志(Л·П·马特维也夫,С·М·     

Undertaking an information-needs analysis of the emergency-care physician to inform the role of the clinical librarian: a Greek perspective

AIM OF STUDY: The primary focus of this pilot study was to gain a better understanding of the information needs of emergency-care clinicians. The secondary focus was to compare the traditional current practice of information provision within other emergency departments in Greek hospitals, with the new model of clinical librarianship (CL). RATIONALE: Clinical staff in the emergency department deal with a variety of cases, they have no time to visit the library, but need information instantly in their place of work. Clinical decision making in the emergency department setting frequently requires the clinician to obtain additional sources of information and clinical librarians may facilitate this. STUDY DESIGN: The present study focused on two professional groups: medical librarians (group A) and clinicians (consultants, senior registrars, registrars, nurses (group B), working in the emergency departments of two Greek hospitals. The study was organized through a questionnaire survey and some in-depth interviews. RESULTS: This study showed that, for 100% of the clinicians in daily practice, the main information needs arise while treating patients, and that information would help in making patient-care decisions. Clinicians made little use of hospital libraries because they are usually under tremendous time pressure. The main outcome of the study was the use of a clinical librarian as an information provider. Clinical librarians supply information to assist decisions, based on this model. This extends the librarian's role in evidence-based medicine, giving much stronger attention to the relevant evidence in clinical practice. CONCLUSIONS: Nowadays, health services are facing organizational change. The introduction of new technology, and rapid growth of medical knowledge creates a demand for new ways of providing information. Clinical librarian programmes may deliver patients specific information in a timely manner. The mission of the clinical librarian is to facilitate access to quality information which is necessary for improving health, and to act as an informationist in the emergency department.
