Accurate knowledge of who knows whom in organizations have important benefits for individual work performance and managerial decision making,but people are not very accurate when recalling connections among others in their social *** present study investigates how holisticanalytic thinking styles influence the extent people can accurately perceive network relationships and choose the right persons to form a coalition in a fictious persuasive task We focused on two dimensions of holistic-analytic thinking style,namely attention to field(as opposed to parts)and interactionist(as opposed to dispositionist)causal theory Results from 281 participants reveals that while individuals with greater attention to field were more accurate in recalling relationships in asocial network those inclined toward interactionism in causal theory were less accurate Furthermore,greater attention to field enhanced the effectiveness of coalition member selection,in part through the mediationof accurate network perception;while interactionism,via the full mediation of network perception,indirectly led to less effective coalition choice.

为了解决荧光粉混合物之间存在的颜色再吸收和配比调控问题，采用高温固相法合成了一系列Ba4-xCe3Na3（PO4）6F2:xEu2+颜色可调荧光粉。在297 nm光激发下，材料呈现双峰发射特征，570 nm黄色发射峰来源于Eu2+的4f65d1→4f7跃迁发射，而380—470 nm范围内的发射来源于Ce3+的4f65d1→4f7跃迁。研究发现，随着Eu2+浓度的增大，材料的发光颜色可以由蓝色变为黄色，色坐标由（0.056,0.069）变为（0.303,0.347）,结合荧光衰减曲线，证明Ce3+到Eu2+存在着明显的能量传递。

采用等离子体化学气相沉积(PECVD)技术通过改变N_2O流量低温制备不同微观结构的镶嵌纳米晶硅的富硅氧化硅(nc-Si/SiO_x)薄膜,利用傅里叶变换红外(FTIR)透射光谱和Raman光谱技术研究薄膜中氢含量和氧含量变化及其对薄膜晶化度、纳米晶硅粒子大小、薄膜混合相比例的影响。实验表明,随着N_2O比例增加,由于逐渐增强的氧化反应阻碍了纳米晶硅的生长,导致晶硅比例减少和非晶成分增加,同时薄膜晶化度下降。混合相中晶界的比例随N_2O先增后减,当N_2O达到一定值时形成稳定界面。

当代国外左翼的生态帝国主义批判

广西大学学报（哲学社会科学版） 2022年第5期44卷 28-35页

作者：徐艳梅聊城大学马克思主义学院

生态帝国主义是指20世纪70年代以来,新自由主义的全球化使西方发达国家的资本霸权突破主权与制度的约束,向全世界范围拓展,以不平等、非正义的方式从落后国家掠夺资源和财富,造成国际间贫富差距和欠发达地区及全球生态环境的持续恶化现... 详细信息

生态帝国主义是指20世纪70年代以来,新自由主义的全球化使西方发达国家的资本霸权突破主权与制度的约束,向全世界范围拓展,以不平等、非正义的方式从落后国家掠夺资源和财富,造成国际间贫富差距和欠发达地区及全球生态环境的持续恶化现象。当代国外左翼学者在马克思主义经典作家帝国主义批判的基础上,结合新帝国主义时代国际垄断资本全球积累过程中对发展中国家的生态掠夺,从不同维度批判了生态帝国主义的非正义性与反生态性,倡导构建生态公平基础上的“全球生态共同体”。正确认识国外左翼学者的生态帝国主义批判,对认识全球生态治理问题的实质和解决途径,以及建设中国特色社会主义生态文明,具有重要意义。

以二次纤维企业生物处理二级出水为对象,通过田口试验设计和方差分析法(ANOVA),考察了聚合氯化铝(PAC)投加量、阳离子聚丙烯酰胺(CPAM)投加量、pH和温度对膜前混凝过程的影响,确定混凝预处理的最佳工艺条件:PAC投加量为1000 mg/L,CPAM投加量为20 mg/L,pH为9,温度为25℃.在此工艺条件下,废水化学需氧量COD值下降至441 mg/L,总悬浮物TSS为4 NTU,污泥体积系数SV为46,色度为23 Units PtCo.在此基础上进行废水的直接膜分离和经混凝预处理后的膜分离实验,研究结果表明,与未经混凝预处理相比,二沉池出水经混凝预处理后,超滤处理10 min,膜通量衰减至70%,废水COD去除率达到60. 2%.这说明混凝法作为膜分离的预处理工艺能提高二次纤维废水膜处理的整体性能.
