以硕士毕业生为研究对象,采用《硕士毕业生职业成熟度问卷》对其职业成熟度进行调查研究发现:硕士毕业生职业成熟度总体处于中等水平,各因素发展不平衡;男生的职业自我认知显著低于女生,职业自信显著高于女生;工科生的职业成熟度显著高于文科生,理科生职业成熟度水平最低;非独生子女的职业自信和职业独立性显著高于独生子女;专业满意度越高的硕士毕业生,其职业成熟度水平越高。高校可以通过建立“内外兼修”的课程体系、“校企共赢”的实践环节、“分类高效”的就业服务、“灵活动态”的评估机制,切实提升硕士生的职业成熟度。

身心发展尚不成熟的大学生的意识形态容易受外在因素的影响。调研显示,当前多数大学生的意识形态立场为中间派,其价值观整体呈积极、健康、向上的发展趋势。然而,部分大学生的意识形态呈现出“左倾”或“右倾”的思想趋势。对大学生意识形态立场的影响因素进行回归分析和多元线性回归分析发现,性别、政治面貌和学历层次具有一定的影响,而媒体和威权人格则是主要影响因素。思政课教学虽然在学生中满意度较高,在学生价值观引导方面起到了一定作用,但对比央视等主流媒体,在意识形态教育上仍需要加强。此外,在思政课教学中,教师素质、教学效果和教学内容三者之间存在中介效应。高校应从突出政治引领、突出创新方法、突出队伍建设和突出教学特色四方面加强对大学生的思想政治教育。

The effect of yttrium(Y)addition on the oxidation behavior of a ni-based directionally solidified single-crystal superalloy is investigated in this *** oxidation tests for samples with different levels of Y addition are conducted at 1100℃ in *** Y content of the samples is determined by the actual pickup amount obtained from an Inductively Coupled Plasma-Atomic Emission Spectrometry *** is discovered that the addition of Y increases the oxide resistance by the scale of an adhesive double-layer oxide,which is composed of Al_(2)O_(3) and spinel ni(Cr,Al)_(2)O_(4).With 70 ppm of Y addition,the oxidation mass gain decreases from 12.6 g/m^(2) for the alloy without Y addition to 5.3 g/m^(2),and the oxidation rate decreases *** addition,the internal nitride disappears after Y doping because of an increase in oxidation scale adherence and a decrease in oxidation *** this study,the alloy with 660 ppm Y addition demonstrates the best oxidation resistance.

Dear Editor,Since the first recognized case of human infection with avian influenza H5ni virus in 1997, the worldwide spread and re-emergence of this highly pathogenic influenza virus have led to 694 human infection cases. Of these cases, 402 died from 2003 to 2015 （http：//***/influenza/ human animal_interface/EN_GIP_20150106Cumulative- ***？ua=l）, with a morbidity rate of 57.9%, which is much higher than that of seasonal influenza H1N1 virus.
