大众文化与大学生思想政治教育

21世纪,随着经济的发展,文化的全球化、网络化相伴突出。西方意识形态通过文化传播对青年产生了不可忽视的影响,甚至动摇了部分大学生对共产主义理想的信仰;另外高校思想政治教育的实效性较难得到全面发挥,从而影响了大学生主流意识形态的提升与巩固。鉴于大众文化对青年学生理想信念产生的严重影响,高校学生思想政治教育需要作出新的思考。     

大鼠吸入原油和汽油对器官损害的组织形态学变化的比较性研究

观察大鼠吸入原油蒸气和汽油蒸气对器官损害的组织形态学变化,可为法医学鉴定和医学的防治提供依据。健康成年SD大鼠25只,随机分为正常对照组、原油实验组、93号无铅汽油实验组、死后对照组,每组5只。建模成功后,在光镜下观察大鼠主要器官的组织形态学变化。动物模型的制作均获得成功,光镜下观察心脏、肺脏、肝脏、肾脏、脑组织细胞形态均有明显的异常改变。大鼠吸入原油蒸气和汽油蒸气对主要器官有明显的损害作用,为法医学鉴定提供了有价值的依据。     

媒介传播中的文化差异与文化意识

传者与受者的文化差异产生传播的意义,文化意识也需要在这种差异中构建和保持。在文化质差中,传者需要保持明确的主流文化意识;在文化位差中,传者需要树立一定的精英文化意识;在文化时差中,传者则需要具备较强的大众文化意识。传受双方如果不存在任何文化差异,那么传者的文化意识也可以淡化乃至取消。     

关于对群体性事件发展规律及对策分析

当前,群体性事件已经成为影响社会稳定的突出问题,作为社会发展进程中的产物,群体性事件伴随着社会发展形态的进化而不断变化,本文试从社会学和政治学的角度对其发展规律进行了分析,并着重探索目前社会条件下对其有较强操作性的解决方案。     

过敏性休克死亡机体内白三烯变化的研究

本研究采用反相洗脱高效液相色谱(HPLC)法检测青霉素和血清过敏休克致死机体中自三烯(Leukotrienes,LTs)。(1)过敏休克前血中未检出LTs的任一组分,休克死亡后检出LTB_4和LTD_4。青霉素过敏血中LTB_4含量是10.10±4.76(ng/ml),LTD_4是26.75±6.55(ng/ml),未检出LTC_4和LTF_4。(2)正常动物肺,脾和肾中均未检出LTs。过敏休克的肺,脾和肾中不仅检出LTB_4和LTD_4,而且在不同脏器中呈规律分布。青霉素过敏肺中LTs_4是23.75±3.80(ng/g),LTD4是58.58±11.39(ng/g))未检出LTC_4和LTE_4。脾中仅有LTB_424.36±3.62(ng/g)。肾中仅有LTD_12.17±2.55(ng/g)。(3)过敏休克致死机体置室温6或12h,或置冰箱48h再测LTs,未见明显变化。(4)青霉素和血清诱发的过敏休克中,LTs的增加和分布是一致的。本研究提示:LTs含量和分布的变化是过敏性休克所共有,可为过敏性休克急死的法医学死因检定提供有价值的证据。     

媒体传播效果与标题制作

标题的制作对扩大媒体的影响力至关重要。《现代媒体编辑技巧》一书的作者引述一项有关报纸的调查显示:参与调查的读者中,56%只阅读标题,而阅读正文的,只有25%。所以该书作者多萝茜·A·鲍尔斯和黛安·L·博登特别强调:"在今天繁忙的社会中,报纸读者在很大程度上只是标题的浏览者"。这一事实告诉我们:要想使媒体有吸引力,就要先使标题有吸引力,否则就可能功亏一篑。     

The Peer Appearance Culture During Adolescence: Gender and Body Mass Variations

The purpose of this research was to examine gender and body mass, as factors linked to perceived experiences within the peer appearance culture. The sample included 215 girls and 200 boys who were either in 7th grade or 10th grade. Students provided self-reports on experiences in three domains: appearance culture among friends (appearance conversations and diet/muscle talk), peer evaluations (peer appearance pressure, appearance teasing, and vicarious peer teasing), and peer acceptance concerns (appearance-based acceptance, peer appearance comparison). The results indicated that although girls reported more appearance conversations, boys perceived more appearance pressure and teasing. Boys also admitted that they talked with friends about muscle building at a rate greater than girls talked about dieting. BMI showed distinct gender patterns. BMI was a key attribute that unified the experiences within the appearance culture for overweight girls. Among the boys, BMI was associated with differentiated experiences for underweight and overweight participants.Associate Professor in Educational Psychology at the University of Washington.

A comparison of the use of visible microspectrometry and high performance thin layer chromatography for the discrimination of aqueous inks used in porous tip and roller ball pens

Ink lines made by porous tip and roller ball pens have been examined by high performance thin layer chromatography (HPTLC) and by transmission microspectrophotometry (VM) in the visible region. Better discrimination between apparently similar coloured inks was obtained with HPTLC but VM has value as an additional technique for ink examination.     

The analysis of casework sized alloy fragments by inductively coupled plasma-optical emission spectrometry (ICP-OES) using discrete nebulisation

A discrete nebulisation technique has been developed for the multi-element analysis of 100-μl solution droplets by inductively coupled plasma-optical emission spectrometry (ICP-OES). The technique increases analytical speed and uses very small solution volumes with only a slight degradation in detection limits when compared to continuous solution introduction.To evaluate its suitability in casework, small alloy fragments were produced by cutting with a hacksaw, sample division and filing. The analysis of fragments from two different brasses indicated that quantitative data could be obtained from fragments as small as 10 μg. The accurate determination of lead, a non-homogeneous constituent of leaded brasses, required sample sizes an order of magnitude greater. Analysis of an alloy of fine grain structure (copper-nickel) demonstrated that quantitative data could be obtained from samples weighing a few micrograms or less.
