Voicing and Devoicing Assimilation of French /s/ and /z/

The present acoustic-phonetic study explores whether voicing and devoicing assimilations of French fricatives are equivalent in magnitude and whether they operate similarly (i.e., complete vs. gradient, obligatory vs. optional, regressive vs. progressive). It concurrently assesses the contribution of speakers' articulation rate to the proportion of voicing (i.e., voicing ratios) in /s/ and /z/ embedded in fricative#stop sequences. Data analyses show that voicing and devoicing assimilation are similar in many regards: the absolute amounts of voicing change are equivalent in magnitude (0.77, 0.78) for the two processes: changes in voicing ratios are accompanied by changes in fricative and preceding vowel durations. These concomitant alterations result in the increased acoustic-phonetic similarity between the assimilated and the non-assimilated forms, suggesting that the two processes might be complete. In addition, the two processes operate regressively and across word-boundary. However, data show that the voicing assimilation of /s/ is not rate dependent, which suggest that it might be obligatory, while the devoicing assimilation of /z/ is rate dependent, which suggest that it might be optional.     

Gender/Body/Machine

This article considers the question of embodiment in relation to gender and whether there are models of artificial intelligence (AI) which can enrol a concept of gender in their design. A central concern for feminist epistemology is the role of the body in the making of knowledge. I consider how this may inform a critique of the AI project and the related area of artificial life (A–Life), the latter area being of most interest in this paper. I explore briefly the tensions between the treatment of the body in different branches of feminist theory, especially the tensions between the approaches of feminist sociology and feminist philosophy. I explore the ways in which writing from category theory and anthropological phenomenology offers rich suggestions as to how the body has been left out of objectivist accounts of epistemology, but struggles to offer an account of why . In its analysis of the links between women, knowledge and the body, feminist revisions of epistemology offer a more convincing why . This is explored briefly through a critique of symbolic AI, and more substantially through the problem of embodiment in artificial life.     

The perception of /r/ and /l/ in syllable-initial and syllable-final position

American English liquids /r/ and /l/ have been considered intermediate between stop consonants and vowels acoustically, articulatorily, phonologically, and perceptually. Cutting (1947a) found position-dependent ear advantages for liquids in a dichotic listening task: syllable-initial liquids produced significant right ear advantages, while syllable-final liquids produced no reliable ear advantages. The present study employed identification and discrimination tasks to determine whether /r/and /l/ are perceived differently depending on syllable position when perception is tested by a different method. Fifteen subjects listened to two synthetically produced speech series—/li/ to /ri/ and /il/ to /ir/—in which stepwise variations of the third formant cued the difference in consonant identity. The results indicated that: (1) perception did not differ between syllable positions (in contrast to the dichotic listening results), (2) liquids in both syllable positions were perceived categorically, and (3) discrimination of a nonspeech control series did not account for the perception of the speech sounds.     

The discrimination learning of the liquids /r/ and /l/ by Japanese speakers

The discrimination learning of the /r/ and /l/ sounds in a single 1-h session by Japanese college students who had received little or no English conversation training was examined. About half of the subjects exhibited significant improvement after this brief amount of training. A three-state Markov model with the unconditioned, intermediate, and conditioned states was applied as a first approximation of the learning of the liquid pairs, learning which is characterized as two-stage all-or-none conditioning. Also found in the study was a significant correlation between the ability to perceive the liquids and the ability to read English as assessed by a cloze procedure. This correlation is interreted in light of general theory on phoneme awareness.     

/n/-/l/音位合并现象的神经机制：来自MMN的证据

采用ERP技术,比较音位合并者与非音位合并者辨别合并音位/n/-/l/的脑电和行为反应。结果发现,非音位合并者在注意前阶段展现了显著的MMN;而音位合并者没有展现MMN,但在晚期展现了一个显著的负波。行为实验发现,相比于音位合并者,非音位合并者在分辨/n/-/l/时正确率更高,反应时更短。这些结果表明：两组被试区分/n/-/l/的能力在早期自动加工阶段就已经有了显著的差异。方言经验可能降低了音位合并者在听觉感觉加工阶段检测合并音位差异的敏感度。     

THE LEGALIST SCHOOL1 AND LEGAL POSITIVISM2

Law is the authoritative principle for the people and is the basis of government; it is what shapes the people.
The Book of Lord Shang, Chap. V, Par. 26.
If the people be led by laws and controlled by punishments, they will try to evade them but have no sense of shame. If they be led by virtue and controlled by the rules of propriety, they will have the sense of shame and will moreover attain character.
Analects, book ii, Chap. iii

Kolb学习风格与中国大学生英语/i/-/I/发音的关系

以中国大学生为对象, 在对其英语/i/-/&;#618;/发音进行声学分析的基础上, 从Kolb经验学习模式入手, 结合其他相关学习者因素, 探讨学习风格与英语/i/-/&;#618;/发音的关系。结果显示, 中国学生发音表现个体差异较大, 其发音水平与学习风格紧密相关：吸收型和发散型学习者表现较好, 集中型学习者较差, 适应型学习者最差。另外, 中国学生发音表现与其英语使用和练习量也有显著正相关, 但与英语学习起始年龄和英语教育年限等其他因素都无直接联系。     

A Chicano/black/white encounter

What happens when members of three ethnic groups spend eighteen hours together in an “Encounter Weekend”? A facilitation style that placed the major responsibility for group progress on the group itself brought about marked behavioral changes among the group participants. The group progressed from distrust, suspicion, and violent rhetoric to effective communication and understanding. The interracial encounter is a powerful social tool that counselors can use to help people develop respect for each other and live together more humanely.
