对当代雕塑观念性的几点思考

现在,很多人开始意识到搞艺术不是“做什么“、“怎么做“,而是“怎么想“的事了。2006年威尼斯双年展的主题是“用思想去观看,用视觉去思维“,展场里几乎见不到传统概念上的雕塑作品,传统的造型、手法、材料被有意无意地回避了。许多艺术作品借用各种可能的媒材,如声、光、电、现成品等综合材料,由技术团队参与合作而成。大量的艺术品用传统的思维观念和欣赏方式已经无法充分解读。当视觉无法完全读懂眼前的作品时,“用思想去观看,用视觉去思维“这样的观看和思维方式便浮现出来。显然,新的思维观念至关重要。新时期以来,雕塑作为造型艺术的“重工业“,在创作的思维观念上一开始就明显滞后。“里星画派“的展览中,雕塑家的作品很少;早期的圆明园画家村里,以雕塑家身

走在边缘

走在边缘是危险的,一不小心跨出界外,可能是跃入雷池,粉身碎骨,可能是另有蹊径,柳暗花明,但总是多了可能,吸引力也在此。不知什么时候开始,谈起中国画必谈传统与现代、传承与创新,甚或"革新"、"革命"、"死亡"等等,足见时世的艰辛和民族心理的脆弱和期盼。但对于一个实践者而言,任何主义都只能是用来摸着过

Study on the contamination and source of chromium in the sea worm jelly in Xiamen

目的了解厦门市市售土笋冻中铬的污染状况,探讨土笋冻中铬的污染来源及预防措施。方法 2012—2014年在厦门市各采样点随机抽取土笋冻样品81份,虫体样品9份,从宁德地区滩涂海域采集可口革囊星虫、淤泥、海水等环境样品6份,依照GB/T 5009.123—2003《食品中铬的测定》中推荐的石墨炉原子吸收光谱法测定样品中铬的含量。结果 81份土笋冻样品中铬含量范围在0.024~17.6 mg/kg之间,平均值为2.17 mg/kg,中位数为1.33 mg/kg,超标率为42.0%(34/81)。添加明胶加工后导致土笋冻中铬含量从1.33 mg/kg升至5.35 mg/kg。从宁德地区滩涂海域采集的星虫、淤泥、海水样品中铬的含量范围分别为2.67~2.70、68.5~77.9和0.038~0.046 mg/kg。结论厦门市市售土笋冻样品中铬的污染情况较为严重,监管部门须加强对土笋冻的原料、加工、销售过程的监控,保证食品安全。Objective To investigate the chromium contamination of sea worm jelly in Xiamen market and to propose the preventive measures against chromium contamination of sea worm jelly based on analysis of the source.Methods A total of 81 samples of sea worm jelly and 9 samples of polypide were collected in Xiamen market from 2012-2014 and 6 samples of Phascolosoma esculenta,silt and seawater were collected from Ningde.The concentrations of Cr in the samples were determined by graphite furnace atomic absorption spectrometry according to GB/T 5009.123-2003.Results The chromium content of 81 samples were 0.024-17.6 mg/kg,the average content was 2.17 mg/kg,and the median was 1.33 mg/kg.The qualified rate was 58.0%.The concentration of Cr in sea worm jelly was changed from 1.33 to 5.35 mg/kg after adding gelatin.The contents of Cr in the Phascolosoma esculenta,silt and seawater from Ningde area were 2.67-2.70,68.5-77.9,0.038-0.046 mg/kg,respectively.Conclusion The chromium contamination in the sea worm jelly was severely in Xiamen.Supervision and monitoring on the raw materials,production,sales of the sea worm jelly should be strengthened to ensure food safety.福建省卫生计生系统食品污染物及有害因素监测方案(闽卫法监函[2014]128号

生猪价格与玉米价格动态调整关系研究

采用回归、Granger检验、协整检验和Enders-Siklos检验研究生猪价格与玉米价格间的动态调整关系。结果表明:两者呈正相关关系,玉米价格是生猪价格变化的Granger原因。生猪价格与玉米价格存在线性协整关系;Enders-Siklos检验表明两者间存在门限惯性长期均衡关系,生猪价格与玉米价格差减少时的调整速度比增加时的调整速度快。价值规律的作用,政府的不同应对措施和生猪生产过程的特点等是上述结果产生的主要原因。提出了改进生猪价格发布信息平台、普及相关信息到基层养猪农户和广大消费者,以形成良好的市场预期;在影响猪价及引导猪农决策的时候充分考虑两价格之间的非对称调整关系等建议

玻璃化冷冻和程序化冷冻方法对人类卵母细胞骨架及其发育潜能的影响

目的探讨玻璃化冷冻和程序化冷冻对人卵母细胞纺锤体定位、细胞骨架及其发育潜能的影响。方法将第2日发育为M_II卵母细胞随机分为对照组、程序化冻融组、玻璃化冻融组(解冻0 h、1 h、3 h)。应用液晶偏振光显微镜(Polscope)成像系统观察卵母细胞纺锤体与第一极体(Pb)的夹角、表面积、卵透明带内层光阻值和外层光阻值。采用扫描电子显微镜和透射电子显微镜观察卵母细胞的表面和内部超微结构。统计2种冻融方法对卵母细胞发育潜能的影响。结果对照组、程序化冷冻解冻培养3 h组和玻璃化冷冻解冻后培养0 h、1 h、3 h组中的纺锤体可见率分别为92.4%、56.4%、11.2%、24.8%、61.1%。与程序化冻融组相比,玻璃化冷冻解冻培养3 h后卵母细胞中纺锤体与Pb的夹角更小(37.3°与68°,P=0.023)。对照组、程序化冻融组和玻璃化冻融后培养3 h组中卵母细胞的纺锤体面积、卵透明带内层光阻值和透明带外层光阻值差异无统计学意义(P>0.05)。与程序化冻融组相比,玻璃化冻融后培养3 h组中卵母细胞表面突起丰富,微绒毛形态较为正常,倒伏在细胞表面,卵透明带边界较为清晰,与对照组较为接近。程序化冻融组的正常受精率(65.7%)明显低于对照组(79.2%,P=0.041),而卵裂率和囊胚形成率与对照组和玻璃化冻融组差异无统计学意义(P>0.05)。玻璃化冻融后培养3 h组中正常受精率、卵裂率、囊胚形成率与对照组相比,差异无统计学意义(P>0.05)。结论相比程序化冷冻,玻璃化冷冻对卵母细胞纺锤体和卵透明带的损伤及对卵母细胞的发育潜能的影响都较小,可以作为卵母细胞冷冻的一种有效方法。国家自然科学青年基金(81701419);;国家自然科学基金面上项目(81571418)~
