| 1 | 幼儿自尊与攻击性行为的特点及其关系显示文摘攻击性行为是儿童时期最具代表性的反社会行为,对儿童的身体、心理以及社会性发展都有显著的不良影响。随着相关研究的不断深入,幼儿个体内部心理因素开始进入研究者的视野,作为人格核心的自我意识系统,尤其是自尊受到了研究者的强烈关注。为了解当前幼儿自尊与攻击性行为的特点,探明二者之间的关系。本研究采用分层整群随机抽样法,以淮南市5所幼儿园15个班的579名幼儿为研究对象,以《3~9岁儿童自尊问卷》和《幼儿社会行为教师评估问卷》为研究工具,请这15个班的30名教师对本班幼儿的自尊与攻击性行为进行问卷评定。结果发现5岁是幼儿自尊和攻击性行为发展的转折期,幼儿自尊和攻击性行为均存在显著的年龄差异和性别差异;5岁幼儿的自尊水平最高,其次是6岁幼儿,最低的是4岁幼儿,女童的自尊水平显著高于男童;6岁幼儿的攻击性行为水平最高,其次是4岁幼儿,最低的是5岁幼儿,男童的攻击性水平显著高于女童;幼儿总体自尊及各个维度与攻击性行为间均存在显著负相关。回归分析结果表明,自尊中的自我胜任感和重要感对攻击性行为具有显著的负向预测作用。家长和教师可以通过提升幼儿的自尊水平来预防或矫正其攻击性行为,为此家长和教师应尊重幼儿,保护幼儿自尊,促进幼儿人格和谐发展;为幼儿创造活动的机会和条件,使其在活动过程中获得并提升自我胜任感;通过积极评价引导幼儿正确认识和评价自己,增强其重要感。 | 卢长娥 Roxanne Fillmore 王勇 | 2016 | 学前教育研究2016,,4: | 13 |
| 2 | 逆行脑灌注压力对猪脑保护作用的实验研究显示文摘目的 探讨逆行脑灌注压力 34~ 4 0mmHg(1mmHg =0 133kPa)是否有益于延长期停循环时的脑保护。方法 16头猪被降温到食管温度 15℃ ,在 12 0min停循环期间随机分为二组 ,组I(8头 )采用逆灌压力 2 3~ 2 9mmHg ;组II(8头 )采用 34~ 4 0mmHg。然后 ,复温至 37℃、体外循环 6 0min。 结果 在逆灌期间 ,组II的脑皮层血流量是基础值的 114 %~ 16 8% ,明显高于组I的 4 3%~ 4 8% ,差异有非常显著性 (P <0 0 1)。逆灌 15min脑组织氧摄取率 ,组I是 (6 2 5± 34) % ,组II是 (6 6 4± 30 ) %。提示组II提供了较多的脑组织氧供。 37℃再灌注期间 ,组II的脑组织氧饱和度和还原血红蛋白恢复到 37℃对照值 ;组I的氧饱和度增高 ,还原血红蛋白明显低于对照值 (P <0 0 1) ,表明组II较好地保存了脑组织对氧的利用能力。脑组织水含量和正常对照组比较无差异。结论 在猪的急性实验模型 ,增加逆灌压力从 2 3~2 9mmHg到 34~ 4 0mmHg可提供较多的脑皮层血流 ,较好地保存了脑组织对再灌注早期氧的利用能力 ,没有明显增加脑水肿。提示逆灌压力 34~ 4 0mmHg有益于深低温延长期停循环时的脑保护。 | 郦志军 叶箭 Michael J Roxanne D | 2003 | 中华胸心血管外科杂志2003,19,5: | 5 |

| 5 | Manufacture and Cytotoxicity of a Lead-free Piezoelectric Ceramic as a Bone Substitute—Consolidation of Porous Lithium Sodium Potassium Niobate by Cold Isostatic Pressing显示文摘Aim The piezoelectric properties and cytotoxicity of a porous lead-free piezoelectric ceramic for use as a direct bone substitute were investigated. Methodology Cold isostatic pressing(CIP) was applied to fabricate porous lithium sodium potassium niobate (Li_(0.06)Na_(0.5)K_(0.44)) NbO_3 specimens using a pore-forming method.The morphologies of the CIP-processed specimens were characterized and compared to those of specimens made by from conventional pressing procedures.The effects of the ceramic on the attachment and proliferation of osteoblasts isolated from the cranium of 1-day-old Sprague-Dawley rats were examined by a scanning electron microscopy (SEM) and methylthiazol tetrazolium(MTT) assay. Results The results showed that CIP enhanced piezoelectricity and biological performance of the niobate specimen, and also promoted an extracellular matrix-like topography of it.In vitro studies showed that the CIP-enhanced material had positive effects on the attachment and proliferation of osteoblasts. Conclusion Niobate ceramic generated by CIP shows a promise for being a piezoelectric composite bone substitute. | Qi Wang Jun Yang Wu Zhang Roxanne Khoie Yi-ming Li Jian-guo Zhu Zhi-qing Chen | 2009 | International Journal of Oral Science2009,1,2: | 3 |
| 6 | 长期使用单一促生长剂的功效显示文摘在养禽业,促生长剂通常是交替使用的。其理由是通过变换使用,对投喂的任何抗菌素来说,潜在的细菌抗药性最小,可以提高日增重与饲料效率。然而,事实上并不总是如此。有证据表明,对某些促生长剂来说,可以连续以单一形式使用而不降低其功效。本文将讨论单一促生长剂的长期使用效果。每隔三、四年,养禽业就会敏感地认识到某些细菌可能已对所用的促生长剂产生了抗药性。这种忧虑并不是基于新的科学发现,而往往是来自人们对抗菌素在人医或兽医上的临床应用所长期存在的认识。只要这些问题还存在,人们就会怀疑作为促生长剂长期使用的抗菌素之功效。在养禽业的饲喂计划中,常常使用不止一种促生长抗菌素(交替使用)。这种交替使用的道理往往是出于直觉而非科学根据。在家禽饲养周期内,通过用一种促生长剂替代另一种,希望最大限度减小对任何投饲的抗菌素可能存在的细菌耐药性,以便最终提高日增重及饲料效率。下面讨论的焦点是抗菌素作为促生长剂单一使用与交替使用的效果比较。近期的一份综述文献指出,像类如维吉尼霉素、黄霉素以及杆菌肽类(杆菌肽锌与亚甲基二水杨酸杆菌肽)在单一长期使用时,并不会降低其功效。 | 夏伦志 蔡东东 ROXANNE LANDON | 1993 | 国外畜牧学(饲料)1993,,4: | 2 |
