城市农民工子女教育问题的调查研究——以HF市某一工地为例

通过对城市中某一施工工地农民工开展问卷调查,结果反映当前在这一工地上农民工关于子女教育问题的基本情况,了解到农民工在其子女教育问题上的努力和遇到的问题,以及其对子女教育问题的态度,调查结果表明目前随迁子女受教育问题主要是：公办学校费用高、门槛高;城市农民工子弟学校教学条件不足;城市农民工子女接受教育不稳定等问题,并提出了针对农民工子女教育的几条相关建议,以期社会、农民工家庭共同改善子女的教育现状.     

儿童早期发展与教育中最重要的内容：动作教育与综合训练

运用文献资料研究、比较、思辨等方法对动作教育在儿童早期发展与教育中的意义、儿童早期动作教育的概念与内容、当前我国幼儿园动作教育现状与困境进行了阐述;指出：儿童动作学习核心经验的研究是中国早期教育中最薄弱的环节,并对进行幼儿动作教育与综合训练学习时应注意的事项等国内外热点问题进行了探讨分析,旨在为落实教育部于2012年9月颁布的《3~6岁儿童学习与发展指南》、促进幼儿的动作教育与综合身体训练的常规化、正规化提供参考依据。     

RADIOGRAPHIC AND ECHOCARDIOGRAPHIC ASSESSMENT OF LEFT ATRIAL SIZE IN 100 CATS WITH ACUTE LEFT‐SIDED CONGESTIVE HEART FAILURE

The aims of this study were to evaluate left atrial size in cats with acute left‐sided congestive heart failure. We hypothesized that left atrial size as determined by thoracic radiography can be normal in cats with acute left‐sided congestive heart failure. One hundred cats with acute left‐sided congestive heart failure in which thoracic radiography and echocardiography were performed within 12 h were identified. Left atrial size was evaluated using right lateral and ventrodorsal radiographs. Measurements were compared to two‐dimensional echocardiographic variables of left atrial size and left ventricular size. On echocardiography, left atrial enlargement was observed in 96% cats (subjective assessment) whereas maximum left atrial dimension was increased (>15.7 mm) in 93% cats. On radiographs left atrial enlargement (subjective assessment) was found in 48% (lateral view), 53% (ventrodorsal view), and 64% (any view) of cats whereas left atrial enlargement was absent in 36% of cats in both views. Agreement between both methods of left atrial size estimation was poor (Cohen's kappa 0.17). Receiver operating characteristic curve analysis identified a maximum echocardiographic left atrial dimension of approximately 20 mm as the best compromise (Youden index) between sensitivity and specificity in the prediction of radiographic left atrial enlargement. Left atrial enlargement as assessed by thoracic radiography may be absent in a clinically relevant number of cats with congestive heart failure. Therefore, normal left atrial size on thoracic radiographs does not rule out presence of left‐sided congestive heart failure in cats with clinical signs of respiratory distress.     

内蒙古鄂尔多斯市市售预包装儿童食品现状调查

对内蒙古鄂尔多斯市东胜区及其周边3个旗的50家超市和小卖店的预包装儿童食品品牌、品种进行了调查分析。结果显示,该市儿童食品品牌多达169个,品种达222种。其中,营养补充类品牌49个(29.0%),品种61种(27.5%);纯粹休闲类品牌120个(71.0%),品种161种(72.5%),且大多属于"垃圾食品"。鄂尔多斯市东胜区在售的儿童食品品牌124个(62.3%),品种180种(59.4%),其他3个旗合计有75个品牌(37.7%),123个品种(59.4%),说明地区经济文化发展水平不同,儿童食品的种类以及档次也存在差异。该次调查的产品包装和标签信息均较为全面,且有QS标识,虽较往年规范了许多,但其品质是否合格尚需进行专业的检验。     

关于中国农村留守儿童问题的调查研究

农村留守儿童已经成为当今一个不容忽视的社会问题。本文通过抽样调查,对比留守儿童和非留守儿童,来研究留守儿童在学习、生活、心理和道德方面出现的问题,并分析了产生这些问题的原因。     

论我国农民工子女入学难的国际公约视角

本文从国际公约的视角,认为无迁徙自由权造成了农民工子女入学难;受教育的不公平造成了农民工子女的读书难;性别不平等造成了农民工女童的升学难;不良的生存环境造成了农民工子女的学习难。     

Feasibility of radial and circumferential strain analysis using 2D speckle tracking echocardiography in cats

The purpose of the present study is to investigate the feasibility of strain analysis using speckle tracking echocardiography (STE) in cats and to evaluate STE variables in cats with hypertrophic cardiomyopathy (HCM). Sixteen clinically healthy cats and 17 cats with HCM were used. Radial and circumferential strain and strain rate variables in healthy cats were measured using STE to assess the feasibility. Comparisons of global strain and strain variables between healthy cats and cats with HCM were performed. Segmental assessments of left ventricle (LV) wall for strain and strain rate variables in cats with HCM were also performed. As a result, technically adequate images were obtained in 97.6% of the segments for STE analysis. Sedation using buprenorphine and acepromazine did not affect any global strain nor strain rate variable. In LV segments of cats with HCM, reduced segmental radial strain and strain rate variables had significantly related with segmental LV hypertrophy. It is concluded that STE analysis using short axis images of LV appeared to be clinically feasible in cats, having the possibility to be useful for detecting myocardial dysfunctions in cats with diseased heart.     

农村留守儿童交往问题的实证研究

通过自行编制的儿童交往量表,对2所农村初级中学和1所小学留守儿童进行抽样调查研究.结果表明,12个方面的交往特征上交往问题检测率分别为:亲情冷漠与憎恨占留守儿童数量的1.7%;孤独与郁闷占23.2%;受歧视占4.7%;亲情梦占51.0%;担忧与失眠占11.7%;学习辅导缺失占1.3%;受欺负与攻击占11.1%;放任与自暴自弃占14.8%;虚拟社区占2.3%;亲情管教缺失占9.4%;亲师占67.8%;疏远老师占17.1%;亲同学占84.9%;疏远同学占11.4%.留守儿童存在着比较严重的交往问题,最为典型的是亲情梦,孤独与郁闷,放任与自暴自弃,担忧与失眠,受欺负与攻击等.留守儿童的交往问题显著地受父母在外打工时间和回家间隔时间长短的影响,时间越长影响越严重.同时存在年级差异和性别差异,年级越低受到的影响越大,4年级留守儿童显著地在各个交往特征上受到最深重的影响.留守儿童女生比男生在交往交流问题上需要更多的关注和帮护.
