This study analyzed the accent perceptions of a group of 37 English language learners and 10 American undergraduate students. Each subject listened to a one-minute passage read by four speakers with different accents of English: General American, British English, Chinese English, and Mexican English. Participants then attempted to identify the different accents and stated their preferences and opinions about each. They also provided background information, including reasons for studying English and pronunciation goals. Additionally, 11 participants were individually interviewed about the different accents. Although more than half (62%) of the learners stated that their goal was to sound like a native English speaker, only 29% were able to correctly identify the American accent. No strong correlations were found between the ability to identify accents and the amount of time spent in the United States nor time studying English. However, an almost perfect correlation was found between the accent voted easiest to understand and the one that participants preferred. The lack of consistency in identifying accents may refl ect an idealized conception of what the native accent aspired to actually sounds like. This fi nding and the priority placed on listening comprehension suggest a need for more thorough consideration of accent in ESOL programs. R ecently, the fi eld of TESOL has seen increasing interest in the role of English as an international language. One facet of this topic is

The STriatal-Enriched protein tyrosine Phosphatase 61 (STEP61) inhibits the activity of the tyrosine kinase Fyn and dephosphorylates the GluN2B subunit of the NMDA receptor, whereas PKA phosphorylation of STEP61 inhibits the activity of the phosphatase (Goebel-Goody et al. 2012). Previously, we found that ethanol activates Fyn in the dorsomedial striatum (DMS) leading to GluN2B phosphorylation, which, in turn, underlies the development of ethanol intake (Wang et al. 2010). Here, we tested the hypothesis that inhibition of STEP61 by ethanol is upstream of Fyn/GluN2B. We show that exposure of mice to ethanol increased STEP61 phosphorylation in the DMS, which was maintained after withdrawal and was not observed in other striatal regions. Specific knockdown of STEP61 in the DMS of mice enhanced ethanol-mediated Fyn activation and GluN2B phosphorylation, and increased ethanol intake without altering the level of water, saccharine, quinine consumption or spontaneous locomotor activity. Together, our data suggest that blockade of STEP61 activity in response to ethanol is sufficient for the activation of the Fyn/GluN2B pathway in the DMS. Being upstream of Fyn and GluN2B, inactive STEP61 in the DMS primes the induction of ethanol intake.

By using a Malmquist total factor productivity index and data envelopment analysis it is possible to investigate the efficiency and productivity of Australian airports during the 1990s. The results from this analysis indicate that these airports recorded strong growth in technological change and total factor productivity, but did not fare all that well in terms of growth in technical and scale efficiency during the 1990s. At the international level it appears that Australia's largest airports fare reasonably well in comparison to airports overseas, although they still possess the potential to realise further gains.
