为应对预付式消费给传统监管体系提出的挑战,一些地方政府利用信息化、互联化的优势,探索建立统一的互联网监管平台。这些平台存在着备案参与度低、平台风险警示制度缺乏互联互通等困境,究其根源是由于政府管控型监管理念与风险预防逻辑不适应;监管权力配置模式过于僵化;制度规范滞后于监管需求;监管工具的创新性不足。为治理上述困境,亟需从政府管控监管理念转换为多元协同监管理念;构建“部门协同、社会共担”的监管权力配置格局;健全“风险预防、程序保障”为导向的监管规范体系;创新监管工具以提高风险预防的精准性等四个方面的改革路径,为治理政府主导型预付式消费互联网平台的监管困境提供思路。

It is claimed that the formula used for calculating the tensile strength of a disk-shaped rock specimen in the Brazilian test is not accurate, because the formula is based on the 2-dimensional elastic theory and only suitable for very long or very short cylinders. The Matlab software was used to obtain the 2-dimensional distribution of stress in the rock specimen for Brazilian test. Then the 2-dimensional stress distribution in Brazilian disk was analyzed by the Marc FEM software. It can be found that the results obtained by the two software packages can verify each other. Finally, the 3-dimensional elastic stress in the specimen was calculated. The results demonstrate that the distribution of stress on the cross section of the specimen is similar to that in 2-dimension. However, the value of the stress on the cross section varies along the thickness of the specimen and the stress is bigger when getting closer to the end of the specimen. For the specimen with a height-to-diameter ratio of 1 and a Poisson＇s ratio of 0.25, the tensile strength calculated with the classical 2-D formula is 23.3% smaller than the real strength. Therefore, the classical 2-D formula is too conservative.

新中国成立以来,我国综合大学参与教师教育经历了初创探索、政策确认、深化发展、跨越式发展四个阶段。教师教育从封闭走向开放,从集权管理到分权尝试,从强制性变迁向诱致性变迁转变,教师教育在发展过程中付出了高昂的构建和固定成本。受原有制度自我强化的学习效应影响,综合大学参与教师教育的阻力增大;受合作效应影响产生的教师教育利益集团,阻碍综合大学参与教师教育进程;受适应性预期影响,综合大学参与教师教育的积极性不高。因此,教师教育改革必须坚持师范院校为主、综合大学参与的基本立场,综合大学参与教师教育的政策支持要做到深化细化,加大教师教育经费投入,建立健全高校评价体制。

A two-step energy injection explanation for the rebrightenings of the multi-band afterglow of GRB 081029

The afterglow of GRB 081029 showed unusual behavior, with a signifi- cant rebrightening being observed at the optical wavelength at about 3000 s after the burst. One possible explanation is that the rebrightening resulted from an energy in- jection. Here we present a detailed numerical study of the energy injection process and interpret the X-ray and optical afterglow light curves of GRB 081029. In our model, we have assumed two periods of energy injection, each with a constant injec- tion power. One injection starts at 2.8 × 10^3 s and lasts for about 2500 s, with a power of 7.0 × 10^47 erg s-1. This energy injection mainly accounts for the rapid rebrighten- ing at about 3000 s. The other injection starts at 8.0 × 10^3 s and lasts for about 5000 s. The injection power is 3.5 × 10^47 erg s-1. This energy injection can help to explain the slight rebrightening at about 10 000 s. It is shown that the observed optical after- glow, especially the marked rebrightening at about 3000 s, can be reproduced well. In the X-ray band, the predicted amplitude of the rebrightening is much shallower, which is also consistent with the observed X-ray afterglow light curve. It is argued that the two periods of energy injection can be produced by clumpy materials falling onto the central compact object of the burster, which leads to an enhancement of accretion and gives rise to a strong temporary outflow.

Long term observations by Brook et al. reveal that the derivative of rotational frequency of PSR J0738-4042 changed abruptly in 2005. Originally, the spin-down rate was relatively stable, with the rotational frequency derivative being - 1.14 x 10-14 s-2. After September 2005, the derivative began to rise. About 1000 days later, it arrived at another relatively stable value of about -0.98 x 10-24 s-2, indicating that the pulsar is spinning-down relatively slowly. To explain the observed change in spin-down rate, we resort to an asteroid disrupted by PSR J0738-4042. In our model, the orbital angular momentum of the asteroid is assumed to be parallel to that of the rotating pulsar, so that the pronounced reduction in the spin-down rate can be naturally explained as due to the transfer of angular momentum from the disrupted material to the central pulsar. The derived magnetospheric radius is about 7.0 x 109 cm, which is smaller than the tidal disruption radius （8.7 x 10^10cm）. Our model is self-consistent. It is shown that the variability in the spin-down rate of PSR J0738-4042 can be quantitatively accounted for by accretion from the asteroid disrupted by the central pulsar.
