基于小生境原理的免疫检测器集优化

基于否定选择的网络入侵检测系统中,检测器集的质量在很大程度上影响检测速率和检测准确率。基于小生境原理,对根据否定选择算法生成的检测器集中存在的重叠检测器进行高频变异和低频变异,提高了检测器集对非自体空间的覆盖率。根据否定选择算法的仿真实验的结果表明优化后的检测器集的整体检测效率明显改善。     

Equatorial aurora: the aurora-like airglow in the negative magnetic anomaly

The most fantastic optical phenomena in the Earth''s upper atmosphere are the auroras. They are highly informative indicators of solar activity, geomagnetic activity, upper atmospheric structures and dynamics, and magnetospheric energetic particles. An area where the geomagnetic field differs significantly from the expected symmetric dipole, such as at the South Atlantic Anomaly, where the magnetic field intensity is low, gives rise to stronger precipitation of energetic particles into the upper atmosphere. Impact excitation and the subsequent airglow emissions exhibit aurora-like dynamic signatures. Nomenclatures of nonpolar aurora or equatorial auroras are similar to those used with the polar auroras owing to their similar excitation mechanisms. This paper provides an overview of the knowledge and the challenges concerning auroral activity at the South Atlantic Anomaly, or more generally, at the negative magnetic anomaly. We emphasize systematic investigation of the equatorial auroras to reveal the temporal and spatial evolution of the magnetic anomaly and the behaviour of energetic particles in near-Earth space.

兴奋剂违规案件的证明责任问题——以“Contador案”为视角

运用案例分析法,将证据法学和体育法学交叉综合,对国际体育仲裁院仲裁庭（CAS）就“Contador案”所作的裁决进行分析。以从CAS的裁决中寻找有益的观点,为完善《世界反兴奋剂条例》及以之为蓝本的其他反兴奋剂条例中关于证明责任分配与证明标准的规定提供借鉴。“Contador案”的裁决采纳了证据法学中将证明责任分为法定说服责任与提供证据的责任的观点,认为不承担法定说服责任的当事人在对方当事人举证困难的情况下,也应承担提供证据协助查明案情的责任。这一观点应当为《世界反兴奋剂条例》所借鉴,以补充细化第3.1条中关于证明责任的规定。     

大学生就业负性心理暗示的归因及应对

由于社会、家庭、学校教育的偏颇,在大学生就业过程中产生了自卑心理、低就心理、造假心理、依赖心理、从众心理、仕途心理、嫉妒心理、攀比心理等负性心理暗示。必须通过学科建设、就业指导、心理辅导、校园网络及校友会等多种管道对大学生就业心理加以引导,以利于大学生就业。

Superior short-term learning effect of visual and sensory organisation ability when sensory information is unreliable in adolescent rhythmic gymnasts

Rhythmic gymnasts specialise in dynamic balance under sensory conditions of numerous somatosensory, visual, and vestibular stimulations. This study investigated whether adolescent rhythmic gymnasts are superior to peers in Sensory Organisation test (SOT) performance, which quantifies the ability to maintain standing balance in six sensory conditions, and explored whether they plateaued faster during familiarisation with the SOT. Three and six sessions of SOTs were administered to 15 female rhythmic gymnasts (15.0 ± 1.8 years) and matched peers (15.1 ± 2.1 years), respectively. The gymnasts were superior to their peers in terms of fitness measures, and their performance was better in the SOT equilibrium score when visual information was unreliable. The SOT learning effects were shown in more challenging sensory conditions between Sessions 1 and 2 and were equivalent in both groups; however, over time, the gymnasts gained marginally significant better visual ability and relied less on visual sense when unreliable. In conclusion, adolescent rhythmic gymnasts have generally the same sensory organisation ability and learning rates as their peers. However, when visual information is unreliable, they have superior sensory organisation ability and learn faster to rely less on visual sense.     

Latino Portrayals in Local News Media: Underrepresentation,Negative Stereotypes,and Institutional Predictors of Coverage

Given the rise in negative rhetoric about Latinos in the U.S., it is essential to examine whether this negative tone extends to general, local news as well. An analysis of 2426 news articles drawn from 55 local newspapers in 2015 reveals several important findings. First, despite the intense spotlight on Latinos, they are still underrepresented in local news media. Relative to the other ethnic groups and whites, Latinos are more likely to be portrayed through negative stereotypes. However, the probability of this negative coverage is smaller for news media with a big proportion of Latino audiences, or for publicly-owned media outlets.
