Relations between acoustic and articulatory measurements of /l/
No full textVariation in the production of English /l/ has received significant study. It has been characterized in terms of categorical allophones, in terms of acoustic properties, and in terms of articulatory timing. Using a parallel corpus of acoustic-articulatory data from two speakers of American English, this study looks at the relations between acoustic and articulatory measurements of /l/ across words in corpus of read speech. We find significant negative correlations between F1 and tongue tip height and significant positive correlations between F2 and tongue body retraction. Additionally, we find that the relative timing of tongue tip and tongue back gestures in our data are consistent with past work on positional variants of /l/
Sharing news, making sense, saying thanks: patterns of talk on Twitter during the Queensland floods
No full textAbstract: This paper examines the discursive aspects of Twitter communication during the floods in the summer of 2010–2011 in Queensland, Australia. Using a representative sample of communication associated with the #qldfloods hashtag on Twitter, we coded and analysed the patterns of communication. We focus on key phenomena in the use of social media in crisis communication: communal sense-making practices, the negotiation of participant roles, and digital convergence around shared events. Social media is used both as a crisis communication and emergency management tool, as well as a space for participants to engage in emotional exchanges and communication of distress.Authored by Frances Shaw, Jean Burgess, Kate Crawford and Axel Bruns

Lack of cerebral BMAA in human cerebral cortex
No full textBioaccumulation of -methylamino-L-alanine (BMAA) through Cyanobacteria-contaminated food or water supplies has been suggested as a possible contributor to Parkinson-dementia complex (PDC) among the indigenous Chamorro of Guam as well as Alzheimer disease (AD) worldwide, a speculation that has been widely commented on in news and editorial sections of premier scientific and medical journals, and that has led to product recalls and government-sponsored assessments of public health in Europe. However, quantification of BMAA to date has been based on indirect high performance liquid chromatography methods. Given the potential global health significance, we developed a stable-isotope dilution assay for BMAA to more rigorously test its proposed bioaccumulation in cerebral cortex.Peer reviewedfinal article publishe

Spec. 33, 569 (1979).Author Institution:Several have shown that line parameter estimates can be obtained from digitized absorption spectra by non-linear regression analysis. We are concerned with the distribution of parameter estimates and estimates of standard deviation obtained by this method of analysis. The most general technique of studying these estimates-is by Five parameters which are used to describe the appearance of a single Lorenzian line, the background, instrument function width, line position, intensity and half width, have been studied in this way. The distributions of estimates are described and contrasted with some results of Niple and $Shaw.^{7}

Lack of behavioral and neuropathological effects of dietary β-methylamino- l-alanine (BMAA) in mice
No full textβ-Methylamino- l-alanine (BMAA) is an excitotoxin allegedly involved in ALS–parkinsonism–dementia complex (ALS–PDC), a neurological disorder found in Guam and its surrounding islands, in which motor neuron disease symptoms can present alone or can co-occur with parkinsonism and dementia. Although in vitro experiments have shown BMAA's neurotoxic properties, studies using adult animals and systemic administration which better model the case of environmentally-induced human neurodegenerative diseases have not supported the involvement of BMAA in these disorders. In order to better test the hypothesized role of BMAA in neurodegeneration, we fed adult mice BMAA at a dose (28 mg/kg body weight, daily for 30 days) that reproduces the natural levels and tested the animals with a battery of behavioural tests, the latter including the evaluation of motor coordination, motor neuron-mediated reflexes, locomotion, muscular strength and memory. We also assessed whether BMAA exposure triggers cell death in the central nervous system (CNS) of mice by examining neuronal numbers and glial response in the spinal cord and the brain. No motor, cognitive or neuropathological outcome resulted from this feeding paradigm. Our findings support neither the causal role of BMAA in neurodegeneration nor the specific involvement of this amino acid in ALS–PDC.Peer reviewedfinal article publishedALS–PDCNeurotoxinNeurodegenerationExcitotoxicityβ-Methylamino-l-alanin
