Speech convergence is the tendency of talkers to become more similar to someone they are listening or talking to, whether that person is a conversational partner or merely a voice heard repeating words. To elucidate the nature of the mechanisms underlying convergence, this study uses different levels of task difficulty on speech convergence within dyads collaborating on a task. Dyad members had to build identical LEGO® constructions without being able to see each other's construction, and with each member having half of the instructions required to complete the construction. Three levels of task difficulty were created, with five dyads at each level (30 participants total). Task difficulty was also measured using completion time and error rate. Listeners who heard pairs of utterances from each dyad judged convergence to be occurring in the Easy condition and to a lesser extent in the Medium condition, but not in the Hard condition. Amplitude envelope acoustic similarity analyses of the same utterance pairs showed that convergence occurred in dyads with shorter completion times and lower error rates. Together, these results suggest that while speech convergence is a highly variable behavior, it may occur more in contexts of low cognitive load. The relevance of these results for the current automatic and socially-driven models of convergence is discussed.

Language learning is a multimodal endeavor; to improve their pronunciation in a new language, learners access not only auditory information about speech sounds and patterns, but also visual information about articulatory movements and processes. With the development of new technologies in computer-assisted pronunciation training (CAPT) comes new possibilities for delivering feedback in both auditory and visual modalities. The present paper surveys the literature on computer-assisted visual articulation feedback, including direct feedback that provides visual models of articulation and indirect feedback that uses visualized acoustic information as a means to inform articulation instruction. Our focus is explicitly on segmental features rather than suprasegmental ones, with visual feedback conceived of as providing visualizations of articulatory configurations, movements, and processes. In addition to discussing types of visual articulation feedback, we also consider the criteria for effective delivery of feedback, and methods of evaluation.

Objectives: To assess the quality of care for patients with diabetes in Queensland hospitals, including blood glucose control, rates of hospital-acquired harm, the incidence of insulin prescription and management errors, and appropriate foot and peri-operative care.Design, setting: Cross-sectional audit of 27 public hospitals in Queensland: four of five tertiary/quaternary referral centres, four of seven large regional or outer metropolitan hospitals, seven of 13 smaller outer metropolitan or small regional hospitals, and 12 of 88 hospitals in rural or remote locations.Participants: 850 adult inpatients with diabetes mellitus in medical, surgical, mental health, high dependency, or intensive care wards.

Background: One common cluster of chronic conditionschronic kidney disease, diabetes mellitus and heart failureplaces a significant burden on the Australian healthcare system. In combination, these conditions complicate treatment, increase rates of hospitalisation and carry a poorer prognosis for survival. Current health services are organised around single conditions, making coordination of care more difficult and adding complexity to patients' lives. Aims: To describe an integrated model of care provided by nurse practitioners for patients with multiple chronic diseases. Methods: A prospective, longitudinal study of patients with two or three chronic diseases attending a community-based nurse practitioner clinic. On entry to the clinic demographic and clinical data were collected from patients and health records (n = 121). At six months a subgroup (n = 70) also reported their satisfaction with the clinic. Findings: Over 18 months the clinic provided 925 appointments to patients aged between 27-90 years. Most (79.2%) had chronic kidney disease as one of their diagnoses. At baseline, blood pressure and glycosylated haemoglobin targets were achieved by 66.4% and 83.2% respectively, although only 7.1% had a healthy-range body mass index. After six months of attendance, there was high overall patient satisfaction with the new service (98.7%). Discussion: Nurse practitioners can reform healthcare delivery through innovative personcentred models of care, breaking down the siloes of treatment for chronic disease. Conclusion: In the current and growing context of multi-morbid chronic health conditions, integration of care within and across organisations is required to meet future health care demands.
