Evaluating the Wiimote as a musical controller

The Nintendo Wiimote is growing in popularity with mu-sicians as a controller. This mode of use is an adaptationfrom its intended use as a game controller, and requiresevaluation of its functions in a musical context in orderto understand its possibilities and limits. Drawing on Hu-man Computer Interaction methodology, we assessed thecore musical applications of the Wiimote and designeda usability experiment to test them. 17 participants tookpart, performing musical tasks in four contexts: trigger-ing; precise and expressive continuous control; and ges-ture recognition. Interviews and empirical evidence wereutilised to probe the device’s limitations and its creativestrengths. This study should help potential users to planthe Wiimote’s employment in their projects, and should beuseful as a case study in HCI evaluation of musical con-trollers

Phalanger: controlling music software with hand movement using a computer vision and machine learning approach

Phalanger is a system which facilitates the control of music software with hand and finger motion, with the aim of creating a fluid style of interaction that promotes musicality. The system is purely video based, requires no wearables or accessories and uses affordable and accessible technology. It employs a neural network for background segmentation, a combination of imaging techniques for frame analysis, and a support vector machine (SVM) for recognition of hand positions. System evaluation showed the SVM to reliably differentiate between eight different classes. An initial formative user evaluation with ten musicians was carried out to help build a picture of how users responded to the system; this highlighted areas that need improvement and lent some insight into useful features for the next version

Changes in health-related quality of life following imprisonment in 92 women in England: a three month follow-up study

<p>Abstract</p> <p>Background</p> <p>Despite the considerable changes in the provision of health care to prisoners in the UK there is little published literature that attempts to examine broader aspects of health and the impact of imprisonment on these, focusing instead on disease specific areas. This is surprising given that one of the main drivers behind the changes was the need for improvements in the quality of care; examining changes in health outcomes should be an important part of monitoring service developments. This study assessed the health-related quality of life of women on entry into prison and examined changes during a period of three months imprisonment.</p> <p>Methods</p> <p>This was a prospective longitudinal study involving 505 women prisoners in England. The SF-36 was contained within a questionnaire designed to examine many aspects of imprisoned women's health. Participants completed this questionnaire within 72 hours of entering prison. The researchers followed up all participants who were still imprisoned three months later.</p> <p>Results</p> <p>The study achieved good response rates: 82% of women agreed to participate initially (n = 505), and 93% of those still imprisoned participating three months later (n = 112). At prison entry, women prisoners have lower mental component summary score (MCS) and physical component summary score (PCS) compared to women within the general population. The mental well-being of those 112 women still imprisoned after three months improved over this period of imprisonment, although remained poorer than that of the general population. The PCS did not improve significantly and remained significantly lower than that of the general population. Multivariate analyses showed that the only independent predictor of change in component score was the score at baseline.</p> <p>Conclusions</p> <p>The results highlight the poor health-related quality of life of women prisoners and highlight the scale of the challenge faced by those providing health care to prisoners. They also draw attention to the major health disadvantages of women offenders compared to women in general. While recent reforms may improve health services for prisoners, broader inequalities in the health of women are a more complex challenge.</p

Review of the state of practice in geovisualization in the geosciences

Geosciences modelling and 3D geovisualization is growing and evolving rapidly. Driven by commercial urgency and an increase in data from sensor-based sources, there is an abundance of opportunities to analyze geosciences data in 3D and 4D. Geosciences modelling is developing in GIS based systems, 3D modelling through both game engines and custom programs, and the use of extended reality to further interact with data. The key limitations that are currently prevalent in 3D geovisualization in the geosciences are GIS representations having difficulty displaying 3D data and undergoing translations to pseudo-3D, thus losing fidelity, financial and personnel capital, processing issues with the terabytes worth of data and limited computing, digital occlusion and spatial interpretation challenges with users, and matching and alignment of 3D points. The future of 3D geovisualization lies in its accelerated growth, data management solutions, further interactivity in applications, and more information regarding the benefits and best practices in the field

Can Early Intervention Policies Improve Well-being? Evidence from a randomized controlled trial *

Many authors have proposed incorporating measures of well-being into evaluations of public policy. Yet few evaluations use experimental design or examine multiple aspects of well-being, thus the causal impact of public policies on well-being is largely unknown. In this paper we examine the effect of an intensive early intervention program on maternal well-being in a targeted disadvantaged community. Using a randomized controlled trial design we estimate and compare treatment effects on global well-being using measures of life satisfaction, experienced well-being using both the Day Reconstruction Method (DRM) and a measure of mood yesterday, and also a standardized measure of parenting stress. The intervention has no significant impact on negative measures of well-being, such as experienced negative affect as measured by the DRM and global measures of well-being such as life satisfaction or a global measure of parenting stress. Significant treatment effects are observed on experienced measures of positive affect using the DRM, and a measure of mood yesterday. The DRM treatment effects are primarily concentrated during times spent without the target child which may reflect the increased effort and burden associated with additional parental investment. Our findings suggest that a maternal-focused intervention may produce meaningful improvements in experienced well-being. Incorporating measures of experienced affect may thus alter cost-benefit calculations for public policies

Can Early Intervention Improve Maternal Well-Being? Evidence from a Randomized Controlled Trial

Objective&nbsp; &nbsp;This study estimates the effect of a targeted early childhood intervention program on global and experienced measures of maternal well-being utilizing a randomized controlled trial design. The primary aim of the intervention is to improve children&rsquo;s school readiness skills by working directly with parents to improve their knowledge of child development and parenting behavior. One potential externality of the program is well-being benefits for parents given its direct focus on improving parental coping, self-efficacy, and problem solving skills, as well as generating an indirect effect on parental well-being by targeting child developmental problems.&nbsp; Methods&nbsp; &nbsp;Participants from a socio-economically disadvantaged community are randomly assigned during pregnancy to an intensive 5-year home visiting parenting program or a control group. We estimate and compare treatment effects on multiple measures of global and experienced well-being using permutation testing to account for small sample size and a stepdown procedure to account for multiple testing.&nbsp; Results&nbsp; The intervention has no impact on global well-being as measured by life satisfaction and parenting stress or experienced negative affect using episodic reports derived from the Day Reconstruction Method (DRM). Treatment effects are observed on measures of experienced positive affect derived from the DRM and a measure of mood yesterday.&nbsp; Conclusion&nbsp; &nbsp;The limited treatment effects suggest that early intervention programs may produce some improvements in experienced positive well-being, but no effects on negative aspects of well-being. Different findings across measures may result as experienced measures of well-being avoid the cognitive biases that impinge upon global assessments
