美国舆论战在现代局部战争中的特点及策略

20世纪90年代以来，以美国为首的北约先后打响了海湾战争、科索沃战争、阿富汗战争和伊拉克战争四场现代局部战争。在这四场战争中，舆论战作为信息化战争时期的一种作战模式，与军事战紧密配合舆论战，主要以敌方意识形态为目标，通过各种媒介或渠道，运用意识渗透、政治进攻、舆论诱导等策略鼓舞士气，凝聚民心，分化瓦解敌对势力，争取国际社会支持，令其发生有利于己而不利于敌的变化，从而达到“不战而屈人之兵”的目的。它是达成国家战略目的不可或缺的重要手段之一。     

社会制作发展探略

电视社会制作经过十年的发展，已经初步形成了一定的规模．仅北京就有超过1000家影视制作机构在从事节目制作和销售工作．并且出现了如光线、嘉实、银汉、唐龙、星美、欢乐、赛迪等颇具规模和实力的公司。而电视剧制作许可证和广播电视节目制作经营许可证的发放也为电视社会制作机构最终确立合法身份开了一个颇有希望的好头。     

Not All Perceptual Gaps Were Created Equal: Explicating the Third-Person Perception (TPP) as a Cognitive Fallacy

Explicating the third-person perception (TPP) as a cognitive fallacy in the process of comparative social judgment of media effects, we propose that not all self–other perceptual gaps in media effects should be considered as TPP. When there is reasonably valid and accurate information regarding self vis-à-vis others on media consumption and vulnerability to media influence, the associated self–other gaps in media effects are not exaggerations, hence, not TPP. TPP results from cognitive biases in information retrieval and application in the process of comparative social judgments. Such biases are in the forms of self-other information differential, assimilation, contrast, and anchoring effects. Caveats in interpretation of extant evidence and implications for future TPP research are discussed.     

平原省建置缘由考

平原省建制始于1949年8月1日,止于1952年11月15日,位于今山东、河南、河北的三省结合部,是中原地区的核心地带。它的设立不仅是其本身发展的需要,还是区域发展的结果。同时,平原省在成立后,各个专区所辖县数量是逐渐减少的,最终趋于稳定,这恰恰反映政区建设就是一个不断探索与优化的过程。     

Simultaneous changes in seed size,oil content and protein content driven by selection of SWEET homologues during soybean domestication

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.
