体坛打假扫黑呼唤司法介入

分析了我国体育界近年来的假球和黑哨现象,指出体坛打假扫黑,必须要有司法介入。然而我国法律制度还不够健全,司法介入体坛困难重重。建议刑法增加体育类犯罪,以完善体育法制。

巩固黑土地粮仓 保障国家粮食安全

粮食安全是国家安全的重要保障。东北黑土区是我国重要的商品粮生产基地,在保障国家粮食安全中起到"压舱石"的作用。但由于该区域耕地的高强度、不合理或过度利用造成了严峻的黑土退化问题。因此,如何使黑土地粮仓高效、可持续地为国家粮食安全提供保障,是当前亟待解决的科学问题。文章系统梳理了改革开放以来黑土地粮仓的农业发展状况;在此基础上,系统总结了黑土地粮食生产可持续发展所面临的问题,并结合中央对东北地区农业生产要求,提出了协调粮食安全和生态安全、增强粮食生产可持续发展的相应对策。以期为东北黑土区农业可持续发展提供参考,为国家粮食战略部署、农业政策制定及国家粮食安全稳固等提供科学指导。     

建构黑人女性主体三部曲——从《最蓝的眼睛》《秀拉》到《宠儿》

托尼·莫里森是迄今唯一获得诺贝尔文学奖的黑人女作家,她以自己独特的女性视角和经验,深入到黑人女性的内心世界,讲述她们在种族和性别的双重压迫之下的身心重创,以至于丧失了作为人的主体性。通过《最蓝的眼睛》《秀拉》和《宠儿》三部作品,作者描述了黑人女性主体从丧失、觉醒反抗到最终建构的艰辛过程。     

有机物料施用量对土壤CO_2排放速率的影响

本试验选用有机碳含量不同的黑土,研究了有机物料施用量对土壤CO2排放速率的影响.研究表明,施用有机物料以后CO2排放速率明显增加,5%和3%处理CO2排放速率增加幅度显著高于2%和1%处理.有机碳分解初期CO2排放速率增加较快,波动性大,后期趋于稳定,其相对值大小随有机物料施用量及土壤有机碳含量增加而增加,即6号土>5号土>4号土>1号土.3号土性质与其它土壤样品略有不同,CO2排放速率偏高.     

The development of attitudes and social characteristics of students attending predominantly black colleges: A longitudinal study

The study was designed to assess the development of Family Independence (FI), Peer Independence (PI), Liberalism (L), Social Conscience (SC), and Cultural Sophistication (CS) among students attending three predominantly black colleges. Responses to the Attitudes section of the College Student Questionnaires were obtained from 334 students when they were entering freshmen, end-of-year freshmen, and graduating seniors. The data were analyzed with a repeated measures multivariate analysis of variance design. College, Sex, and Time were the independent variables, and the five attitude scales were the dependent variables. The tests for the main effects of time revealed overall gains on all five scales. A significant Sex × Time interaction indicated that PI scores for males increased, while females' PI scores decreased, during the freshman year; the females' PI scores increased during the subsequent three year period. Significant College × Time interactions were found for FI and CS. College × Sex × Time interactions were significant for L and CS. The results indicated that students who attended these predominantly black colleges developed greater self-reliance and autonomy and broadened interests in political, social, and cultural affairs. The extent of change in these attitudes varied, however, according to the college attended and/or sex of the student.     

20世纪美国黑人文学三次高潮中的人性变化

美国黑人文学在人性主题的认识和发展方面经历了复杂曲折的变化。这种变化与黑人民族觉醒与抗争的政治斗争相伴而行,也与黑人作家和民众对自我身份认同和对人性认知的逐步深入直接相关。在整个20世纪里,经过大致三个时期的发展和变化,黑人文学逐渐成熟起来,步人世界文学的前列,其对人性的认识和分析也变得冷静而客观,达到了文学艺术的巅峰。     

氧化絮凝法处理活性大黑染料废水的研究

以硫酸铝铁溶液为絮凝剂,高锰酸钾溶液为氧化剂,采用氧化絮凝的方法处理活性大黑染料废水,考察了絮凝剂与氧化剂用量比、絮凝时间、温度、pH等对脱色率和CODCr去除率的影响,确定最佳条件：絮凝剂与氧化剂的摩尔比为3.45∶0.14,pH=1,θ=30℃,絮凝时间t=1 h,脱色率可达99.13%,CODCr去除率达66.81%.如果采用两段处理法,脱色率可进一步提高到99.88%,CODCr去除率达85.13%.砖末二次吸附后,脱色率达99.24%,CODCr去除率达77.05%.     

EAG and behavioral responses of Helicoverpa armigera males to volatiles from poplar leaves and their combinations with sex pheromone

Electroantennogram (EAG) evaluation of selected compounds from wilted leaves ofblack poplar,Populus nigra,showed that phenyl acetaldehyde, methyl salicylate, (E)-2-hexenal elicited strong responses from male antennae of Helicoverpa armigera. When mixed with sex pheromone (Ph), some volatiles, e.g. phenyl acetaldehyde, benzyl alcohol,phenylethanol, methylsalicylate, linalool, benzaldehyde, (Z)-3-hexenol, (Z)-3-hexenylacetate, (Z)-6-nonenol, cineole, (E)-2-hexenal, and geraniol elicited stronger responses from male antennae than Ph alone. Wind tunnel bioassay demonstrated that various volatiles could either enhance or inhibit the effect of synthetic sex pheromone. (E)-2-hexenal, (Z)-3-hexenol and linalool in combination with Ph could not induce any male to land on source at all, whereas phenyl acetaldehyde, benzaldehyde, (Z)-6-nonenol and salicylaldehyde combined with Ph enhanced male response rates by 58.63%,50.33%, 51.85% and 127.78%, respectively, compared to Ph alone. These results suggested that some volatiles should modify sex pheromone caused behavior and that some of them could possibly be used as a tool for disrupting mating or for enhancing the effect of synthetic sex pheromone in the field.     

《最蓝的眼睛》中的文化霸权研究

《最蓝的眼睛》是美国黑人女作家托尼.莫里森的处女作。文本揭示出:在白人对黑人实行文化霸权过程中,知识机构起着不可忽视的作用;大众传媒作为文化霸权机构,在社会中广泛传播白人文化,对黑人心理造成极大伤害,它与统治主体是一种共谋关系。
