Time‐simultaneous prediction band for a time series

I propose principles and methods for the construction of a time‐simultaneous prediction band for a univariate time series. The methods are entirely based on a learning sample of time trajectories, and make no parametric assumption about its distribution. Hence, the methods are general and widely applicable. The expected coverage probability of a band can be estimated by a bootstrap procedure. The estimate is likely to be less than the nominal level. Expected lack of coverage can be compensated for by increasing the coverage in the learning sample. Applications to simulated and empirical data illustrate the methods.

完善我国反贿赂犯罪之刑法立法的若干思考——来自国际反贿赂犯罪立法发展的借鉴

面对贿赂犯罪表现形式日趋多样,跨国贿赂、赃款向境外转移、贪官外逃现象日益严重的严峻局势,国际社会在立法上做出积极而迅速的反应。我国作为国际社会的一员,在贿赂犯罪问题上也面临相同的威胁,但我国刑法的相关规定却落后于国际反贿赂犯罪立法的发展。因此,我们应当借鉴国外立法的成功经验,在贿赂犯罪的范围、行为对象、刑罚种类等方面完善我国的刑法规范。     

Perceptual learning of dot pattern

Dot pattern is a type of pattern defined by specific spatial relationship among some dots. As a compensation for concrete and meaningful visual stimuli, meaningless dot pattern can be used as stimuli in learning tasks. We performed an experiment for exploring the perceptual learning process of dot pattern against random-dot background. Participants were required to learn two types of dot patterns (9-dot and 11-dot). They were assigned to two groups: participants in Group 1 learned 9-dot pattern first and 11-dot pattern later, while those in Group 2 learned 11-dot pattern first and 9-dot pattern later. The results showed that participants could acquire the spatial relationship of dot pattern through perceptual learning in relatively short learning time. In comparison with 9-dot pattern, learning time of 11-dot pattern was slightly longer and its accuracy rate lower, but there was significant positive transfer effect from 11-dot pattern learning to 9-dot learning.
