Large area amorphous silicon photodiode arrays for radiotherapy and diagnostic imaging

Amorphous silicon imaging devices consisting of two-dimensional pixel arrays of photodiodes and field effect transistors can now be fabricated over areas as large as 30 cm by 30 cm. Such imagers can offer considerable advantages for real-time radiotherapy megavoltage and diagnostic X-ray imaging applications. The design, operation, and advantages of such imagers are discussed, and sensor signal data are presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29013/1/0000042.pd

Rating the intelligibility of dysarthic speech amongst people with Parkinson’s Disease: a comparison of trained and untrained listeners

Intelligibility of speech is a key outcome in speech and language therapy (SLT) and research. SLT students frequently participate as raters of intelligibility but we lack information about whether they rate intelligibility in the same way as the general public. This paper aims to determine if there is a difference in the intelligibility ratings made by SLT students (trained in speech related topics) compared to individuals from the general public (untrained). The SLT students were in year 2 of a BSc programme or the first 6 months of a MSc programme. We recorded 10 speakers with Parkinson’s disease (PD) related speech reading aloud the words and sentences from the Assessment of Intelligibility of Dysarthric Speech. These speech recordings were rated for intelligibility by ‘trained’ raters and ‘untrained’ raters. The effort required to understand the speech was also reported. There were no significant differences in the measures of intelligibility from the trained and untrained raters for words or sentences after adjusting for speaker by including them as a covariate in the model. There was a slight increase in effort reported by the untrained raters for the sentences. This difference in reported effort was not evident with the words. SLT students can be recruited alongside individuals from the general public as naïve raters for evaluating intelligibility in people with speech disorders

Meanings of being received and met by others as experienced by women with MS

In order to elucidate meanings of being received and met by others as experienced by women with multiple sclerosis (MS) we conducted a qualitative inquiry. We interviewed 15 women with MS and analysed the interviews with a phenomenological hermeneutic interpretation. The findings were presented in two themes: experiencing oneself as a valuable person and experiencing oneself as diminished. Meanings of being received and met by others, as experienced by women with MS, can be understood as containing two dimensions where treatment from others can mean recognising oneself through confirmation, as well as being ignored due to missing togetherness with others

Brand Suicide? Memory and Liking of Negative Brand Names

Negative brand names are surprisingly common in the marketplace (e.g., Poison perfume; Hell pizza, and Monster energy drink), yet their effects on consumer behavior are currently unknown. Three studies investigated the effects of negative brand name valence on brand name memory and liking of a branded product. Study 1 demonstrates that relative to nonnegative brand names, negative brand names and their associated logos are better recognised. Studies 2 and 3 demonstrate that negative valence of a brand name tends to have a detrimental influence on product evaluation with evaluations worsening as negative valence increases. However, evaluation is also dependent on brand name arousal, with high arousal brand names resulting in more positive evaluations, such that moderately negative brand names are equally as attractive as some non-negative brand names. Study 3 shows evidence for affective habituation, whereby the effects of negative valence reduce with repeated exposures to some classes of negative brand name
