    Black Holes and Vacuum Cleaners: Using Metaphor, Relevance, and Inquiry in Labels for Space Images

    Full text link
    This study extended research on the development of explanatory labels for astronomical images for the non-expert lay public. The research questions addressed how labels with leading questions/metaphors and relevance to everyday life affect comprehension of the intended message for deep space images, the desire to learn more, and the aesthetic appreciation of images. Participants were a convenience sample of 1,921 respondents solicited from a variety of websites and through social media who completed an online survey that used four high-resolution images as stimuli: Sagittarius A*, Solar Flare, Cassiopeia A, and the Pinwheel Galaxy (M101). Participants were randomly assigned initially to 1 of 3 label conditions: the standard label originally written for the image, a label with a leading question containing a metaphor related to the information for the image, or a label that contained a fact about the image relevant to everyday life. Participants were randomly assigned to 1 image and compared all labels for that image. Open-ended items at various points asked participants to pose questions to a hypothetical astronomer. Main findings were that the relevance condition was significantly more likely to increase wanting to learn more; the original label was most likely to increase overall appreciation; and, smart phone users were more likely to want to learn more and report increased levels of appreciation. Results are discussed in terms of the need to examine individual viewer characteristics and goals in creating different labels for different audiences.Comment: 50 pages, 7 tables, 2 figures, accepted by the journal "Psychology of Aesthetics, Creativity, and the Arts

    Work of Health Educators in a Clinical Setting

    This study examined the task of health educators working in a clinical setting to better understand their roles. The study was designed as a descriptive, cross-sectional survey using a convenience sample of health educators who worked in clinical settings in Indiana and who had a college degree in health education. Forty health educators were contacted and 62% of the subjects participated in the survey. Results indicated most jobs were similar in nature and the health education curriculum studied helped them in the roles they were serving. However, many educators felt there were other content areas of study that would have been helpful to prepare them for working in the clinical setting. A majority of the respondents reported that having Certified Health Education Specialist (CHES) certification was helpful and necessary in their positions

The study was designed as a descriptive, cross-sectional survey using a convenience sample of health educators who worked in clinical settings in Indiana and who had a college degree in health education. Forty health educators were contacted and 62.5% of the subjects participated in the survey. Results indicated most jobs were similar in nature and the health education curriculum studied helped them in the roles they were serving. However, many educators felt there were other content areas of study that would have been helpful to prepare them for working in the clinical setting.

    Context, Curriculum, and Community Matter: Leadership Practices of Primary School Principals in the Otago Province of New Zealand

    Get PDF
    This research examined the leadership practices of rural primary school principals in the Otago province of New Zealand. Principals of large (\u3e150 students) and small (students) rural schools served as participants in an investigation to learn how their practice creates and maintains effective rural schools. The goals were to investigate the interrelationships of principal, curriculum, and community and effective leadership in their schools. A mixed methods approach included a survey completed by rural principals (n = 63), followed by observations and interviews. Key findings were that leadership practices varied across contexts of large rural and small rural schools; having a local curriculum was critical; and, communication and involvement with parents and the community were essential. The survey had good psychometric qualities; validation through future research use is needed. Results are discussed in terms of factors to consider for effective leadership in rural schools

    SonoNet: Real-Time Detection and Localisation of Fetal Standard Scan Planes in Freehand Ultrasound

    Get PDF
    Identifying and interpreting fetal standard scan planes during 2D ultrasound mid-pregnancy examinations are highly complex tasks which require years of training. Apart from guiding the probe to the correct location, it can be equally difficult for a non-expert to identify relevant structures within the image. Automatic image processing can provide tools to help experienced as well as inexperienced operators with these tasks. In this paper, we propose a novel method based on convolutional neural networks which can automatically detect 13 fetal standard views in freehand 2D ultrasound data as well as provide a localisation of the fetal structures via a bounding box. An important contribution is that the network learns to localise the target anatomy using weak supervision based on image-level labels only. The network architecture is designed to operate in real-time while providing optimal output for the localisation task. We present results for real-time annotation, retrospective frame retrieval from saved videos, and localisation on a very large and challenging dataset consisting of images and video recordings of full clinical anomaly screenings. We found that the proposed method achieved an average F1-score of 0.798 in a realistic classification experiment modelling real-time detection, and obtained a 90.09% accuracy for retrospective frame retrieval. Moreover, an accuracy of 77.8% was achieved on the localisation task.Comment: 12 pages, 8 figures, published in IEEE Transactions in Medical Imagin

    Individual score validity and student effort in higher education assessment

    This study explored the use of the five invalidity flags plus a new sixth flag based on self-reported effort. Participants were 155 entering first-year university students who were measured during an orientation week and again 18 months later. The instruments were a faculty-developed test of oral communications skills with 40 four-option multiple-choice items and a self-reported measure of test-taking motivation (Student Opinion Survey; Sundre, 1999 adapted from Wolf and Smith, 1995). Results indicated that the Flags explored in this study generalized well to university students. There was a moderate correlation between Response Time Effort and Effort as measured by the Student Opinion Scale, suggesting there was a relationship not captured by the dichotomized flags
