多年来，群众演员安全事件不时发生，相较于专业演员的高收入，他们的工作却是高风险低回报。因此，众多报道将群众演员甘愿忍受恶劣现状的原因片面归结为不切实际的“明星梦”。为此，笔者专赴横店影视城，走近群众演员，了解他们的真实生存现状，还原“明星梦”背后的辛酸现实。

该文研究了不同话题转换方式和句子长度对边界处停顿、边界前延长量及音高重置的影响.语料是由两个句子构成的小语篇,通过改变第二个句子控制两种句子长度(短和长)和三种话题转换方式(延续、精述和转折).20位发音人的语音分析结果显示:(1)话题转换方式和句子长度对停顿及音高重置都有调节作用,但对边界前词的时长延长量没有显著影响.另外,两因素间没有交互作用.主要表现为:边界后句子越长,句间停顿越长,且边界处的音高重置越大.从话题延续、话题精述到话题转折,停顿时长呈增长趋势,且音高重置度增大;(2)停顿时长与边界前延长量存在较弱的负相关,与音高重置则存在较弱的正相关;(3)相较于男性发音人,女性发音人对话题转换方式更为敏感,且更倾向于用停顿和音高两种声学线索标记话题转换方式.句长效应则在男女发音人中都稳定存在.以上结果表明,句长对边界处声学参数的影响基于底层发音机制,而话题转换方式的影响则是语言中信息传递的需要.

We propose in this paper a series of flexible teaching methods for computer bilingual courses based on practice experience of existing bilingual courses.The details include ratio of English teaching,textbook choosing,practice teaching and other implementation strategy.Moreover,to reduce lack of connection among bilingual course,a progressive method used to enhance bilingual teaching is provided properly.

The present study investigated prosodic realization of focus in statement and yes/no question in Tibetan (Lhasa dialect). Two target sentences were uttered by 8 speakers in both statement and yes/no question under four focus conditions, initial, medial, final and neutral focus. Systematic acoustic analysis showed that: (1) On-focus words exhibited significant F0 rising, pitch range expansion, and duration lengthening, while pitch range of pre-focus words remained largely intact. Importantly, focus led to post-focus F0 lowering and compression. Focus was realized the same way in both statement and question. (2) Interrogative intonation had higher F0 than statement in unfocused words. In general, the prosodic realization of focus in Tibetan was comparable to English and Beijing Mandarin. The distribution and origin of post-focus compression (PFC) was also discussed.

* Prosodic marking of focus has been found to be typologically different in terms of existence of post-focus compression in F0 and intensity (PFC). In the current production experiments, we found that PFC showed in Mandarin, but not in Tsat (a language spoken in Hainan, China) or in Tsat-Mandarin (Mandarin spoken by Tsat people). The perception experiments further showed that focus perception in Tsat-Mandarin and Tsat was relatively low (about 30%). An interesting finding was that the perception of focus in Mandarin by Tsat listeners was much lower than that by Mandarin listeners (54.8% vs. 75.6%). In other words, it revealed the difficulty of speakers from a non-PFC language associating PFC with focus perception. It could partly explain why PFC is hard to be passed through language contact.

This paper studied effects of topic structure and sentence length on acoustic parameters at intonational phrases boundaries, comparing female and male speakers. Twenty native speakers of Mandarin Chinese read 12 short discourses, which contained two sentences. The second sentence was either short or long. And, the transition between the two sentences was either topic continuation, topic elaboration or topic shift, by varying the second sentence. Extensive acoustic analysis showed that [1] for the female speakers, both topic structure and sentence length had significant effects on pause duration and pitch reset, but not on final lengthening, whereas for the male speakers, only sentence length had such an effect. [2] A negative correlation between pause duration and pre-boundary lengthening was found for both the female and the male speakers. However, a positive correlation between pause duration and pitch reset was found only for the females, but not for the males. In general, the female speakers used combined acoustic cues for marking topic structure, whereas the male speakers did not mark topic structure systematically. Effect of sentence length on pause duration is robust while all the other conditions are controlled.

In this paper,we propose an active content access control device whose uniqueness lies on built-in intelligence powered by a specially designed USB controller and application firmware.The device functions standalone as a universal security key to unlock virtually all commonly used secure information storage volumes,as long as user identity,assigned privileges,and dynamic authorizations are provided properly.A variety of real world use cases demonstrate significant improvement in effectiveness and flexibility for secure information management.

We propose in this paper an inter-process communication hijacking scheme to intercept,filter,redirect,and modify virtually all commonly used inter-process communication mechanisms in running processes,without requiring recompilation,re-linkage and access to the source codes.Its implementation is orchestrated completely in the user space without kernel modifications and exploitation of potential security vulnerabilities.The hijack scheme demonstrates huge potentials when applied to software dynamic upgrades,system security monitoring and auditing,and software analyses.
