Validation of the NANA (Novel Assessment of Nutrition and Ageing) touch screen system for use at home by older adults

Prospective measurement of nutrition, cognition, and physical activity in later life would facilitate early detection of detrimental change and early intervention but is hard to achieve in community settings. Technology can simplify the task and facilitate daily data collection. The Novel Assessment of Nutrition and Ageing (NANA) toolkit was developed to provide a holistic picture of an individual's function including diet, cognition and activity levels. This study aimed to validate the NANA toolkit for data collection in the community. Forty participants aged 65 years and over trialled the NANA toolkit in their homes for three 7-day periods at four-week intervals. Data collected using the NANA toolkit were compared with standard measures of diet (four-day food diary), cognitive ability (processing speed) and physical activity (self-report). Bland–Altman analysis of dietary intake (energy, carbohydrates, protein fat) found a good relationship with the food diary and cognitive processing speed and physical activity (hours) were significantly correlated with their standard counterparts. The NANA toolkit enables daily reporting of data that would otherwise be collected sporadically while reducing demands on participants; older adults can complete the daily reporting at home without a researcher being present; and it enables prospective investigation of several domains at once

Design and formative evaluation of an information kiosk on cattle health for landless cattle owners

This paper describes and analyses the experience of designing, installing and evaluating a farmer-usable touch screen information kiosk on cattle health in a veterinary institution in Pondicherry. The contents of the kiosk were prepared based on identified demands for information on cattle health, arrived at through various stakeholders meetings. Information on these cattle diseases and conditions affecting the livelihoods of the poor was provided through graphics, text and audio back-up, keeping in mind the needs of landless and illiterate poor cattle owners. A methodology for kiosk evaluation based on the feedback obtained from kiosk facilitator, critical group reflection and individual users was formulated. The formative evaluation reveals the potential strength this ICT has in transferring information to the cattle owners in a service delivery centre. Such information is vital in preventing diseases and helps cattle owners to present and treat their animals at an early stage of disease condition. This in turn helps prevent direct and indirect losses to the cattle owners. The study reveals how an information kiosk installed at a government institution as a freely accessible source of information to all farmers irrespective of their class and caste can help in transfer of information among poor cattle owners, provided periodic updating, interactivity and communication variability are taken care of. Being in the veterinary centre, the kiosk helps stimulate dialogue, and facilitates demand of services based on the information provided by the kiosk screens.

The validation of a computer-based food record for older adults: the Novel Assessment of Nutrition and Ageing (NANA) method

Dietary assessment in older adults can be challenging. The Novel Assessment of Nutrition and Ageing (NANA) method is a touch-screen computer-based food record that enables older adults to record their dietary intakes. The objective of the present study was to assess the relative validity of the NANA method for dietary assessment in older adults. For this purpose, three studies were conducted in which a total of ninety-four older adults (aged 65–89 years) used the NANA method of dietary assessment. On a separate occasion, participants completed a 4 d estimated food diary. Blood and 24 h urine samples were also collected from seventy-six of the volunteers for the analysis of biomarkers of nutrient intake. The results from all the three studies were combined, and nutrient intake data collected using the NANA method were compared against the 4 d estimated food diary and biomarkers of nutrient intake. Bland–Altman analysis showed a reasonable agreement between the dietary assessment methods for energy and macronutrient intake; however, there were small, but significant, differences for energy and protein intake, reflecting the tendency for the NANA method to record marginally lower energy intakes. Significant positive correlations were observed between urinary urea and dietary protein intake using both the NANA and the 4 d estimated food diary methods, and between plasma ascorbic acid and dietary vitamin C intake using the NANA method. The results demonstrate the feasibility of computer-based dietary assessment in older adults, and suggest that the NANA method is comparable to the 4 d estimated food diary, and could be used as an alternative to the food diary for the short-term assessment of an individual’s dietary intake.

Narrativising the facts: acting in screen and stage docudrama

This article presents findings and seeks to establish the theoretical markers that indicate the growing importance of fact-based drama in screen and theatre performance to the wider Anglophone culture. During the final decade of the twentieth century and the opening one of the twenty-first, television docudrama and documentary theatre have grown in visibility and importance in the UK, providing key responses to social, cultural and political change over the millennial period. Actors were the prime focus for the enquiry principally because so little research has been done into the special demands that fact-based performance makes on them. The main emphasis in actor training (in the UK at any rate) is, as it always has been, on preparation for fictional drama. Preparation in acting schools is also heavily geared towards stage performance. Our thesis was that performers called upon to play the roles of real people, in whatever medium, have added responsibilities both towards history and towards real individuals and their families. Actors must engage with ethical questions whether they like it or not, and we found them keenly aware of this. In the course of the research, we conducted 30 interviews with a selection of actors ranging from the experienced to the recently-trained. We also interviewed a few industry professionals and actor trainers. Once the interviews started it was clear that actors themselves made little or no distinction between how they set about their work for television and film. The essential disciplines for work in front of the camera, they told us, are the same whether the camera is electronic or photographic. Some adjustments become necessary, of course in the multi-camera TV studio. But much serious drama for the screen is made on film anyway. We found it was also the case that young actors now tend to get their first paid employment before a camera rather than on a stage. The screen-before-stage tendency, along with the fundamental re-shaping that has gone on in the British theatre since at least the early 1980s, had implications for actor training. We have also found that theatre work still tends to be most valued by actors. For all the actors we interviewed, theatre was what they liked doing best because it was there they could practice and develop their skills, there they could work most collectively towards performance, and there they could more directly experience audience feedback in the real time of the stage play. The current world of television has been especially constrained in regard to rehearsal time in comparison to theatre (and, to a lesser extent, film). This has also affected actors’ valuation of their work. Theatre is, and is not, the most important medium in which they find work. Theatre is most important spiritually and intellectually, because in theatre is collaborative, intensive, and involving; theatre is not as important in financial and career terms, because it is not as lucrative and not as visible to a large public as acting for the screen. Many actors took the view that, for all the industrial differences that do affect them and inevitably interest the academic, acting for the visible media of theatre, film and television involved fundamentally the same process with slightly different emphases.

Multi-finger grasps in a dynamic environment

Most current state-of-the-art haptic devices render only a single force, however almost all human grasps are characterised by multiple forces and torques applied by the fingers and palms of the hand to the object. In this chapter we will begin by considering the different types of grasp and then consider the physics of rigid objects that will be needed for correct haptic rendering. We then describe an algorithm to represent the forces associated with grasp in a natural manner. The power of the algorithm is that it considers only the capabilities of the haptic device and requires no model of the hand, thus applies to most practical grasp types. The technique is sufficiently general that it would also apply to multi-hand interactions, and hence to collaborative interactions where several people interact with the same rigid object. Key concepts in friction and rigid body dynamics are discussed and applied to the problem of rendering multiple forces to allow the person to choose their grasp on a virtual object and perceive the resulting movement via the forces in a natural way. The algorithm also generalises well to support computation of multi-body physics
