Evaluating the Use of Daily Care Notes Software for Older People with Dementia

There has been little research to investigate the impact of software to support the care for older people with dementia care. This article reports the evaluation of software adapted to support one key person-centered task for the care of older residents with dementia – recording and sharing daily care notes. The evaluation on the dementia wing of 1 residential home for over 6 months revealed that use of the software on mobile devices carried by the carers increased the number and volume of daily care notes recorded, but only for the types of content that were already being recorded by carers. Carers reported more advantages that resulted from daily care notes once in digital form than from the documenting task, as well as barriers to the use of mobile digital software to record daily care notes.     

Social Roles in an Online Support Community for Older People

In this article, an online support community for older people is studied, with the aim of developing a taxonomy of social roles based on content analysis and social network analysis. Four hundred messages (posted between August 9, 2007, and February 5, 2008) in an online support community for older people (http://www.seniornet.org) were investigated. The data were analyzed to identify and shed light on patterns of the online functional behavior as well as the social structure of active members. Drawing on the findings, a set of six social roles were identified, defined, and described in depth. The findings showed that the structural positions of online community members were associated with the kind of content these members tended to post. For example, it was found that central members were very likely to give support, whereas members not very well connected were more inclined to post self-disclosing messages.

Multimodal Computer-Mediated Communication and Social Support among Older Chinese Internet Users

Using the grounded theory approach, this ethnographic study examines the relationship between the use of three different modes of computer-mediated communication (CMC) and the types of social support exchanged within an online community of older Chinese (age 50 or older). The findings indicate that the voice chat room is best suited for companionship while the online forum is used primarily for informational support. The exchange of emotional and instrumental support is most likely to occur via instant messaging (IM). These findings suggest that each of these particular modes of CMC, due to its inherent features, may be specialized to sustain certain interactions and relationships. Yet, because older Chinese in this study employ multiple modes of CMC to interact and develop relationships, the overall relationships developed through CMC are multidimensional.     

Accessibility Support for Older Adults with the ACCESS Framework

Equitable access to the digital economy is predicated on the usability of the devices that are used to access electronic goods and services, with computers being the primary mechanism for many users by which this is currently done. For novice users with special interaction requirements, current arrangements for enabling accessibility support are suboptimal. Older users in particular require special consideration with regards to the design of software support packages to ensure the burden of knowledge required to configure a system is reasonable. This article describes the ACCESS Framework, a novel open-source, plug-in enabled software framework designed to address some of the issues around providing accessibility support on the desktop. The framework employs a system through which corrections are successively adapted to an individual user's preferences. Through empirical work with older adults, the framework has been shown to provide an understandable, appropriate, and effective way to enable accessibility support.

A Knowledge Discovery System with Support for Model Selection and Visualization

The process of knowledge discovery in databases consists of several steps that are iterative and interactive. In each application, to go through this process the user has to exploit different algorithms and their settings that usually yield multiple models. Model selection, that is, the selection of appropriate models or algorithms to achieve such models, requires meta-knowledge of algorithm/model and model performance metrics. Therefore, model selection is usually a difficult task for the user. We believe that simplifying the process of model selection for the user is crucial to the success of real-life knowledge discovery activities. As opposed to most related work that aims to automate model selection, in our view model selection is a semiautomatic process, requiring an effective collaboration between the user and the discovery system. For such a collaboration, our solution is to give the user the ability to try various alternatives and to compare competing models quantitatively by performance metrics, and qualitatively by effective visualization. This paper presents our research on model selection and visualization in the development of a knowledge discovery system called D2MS. The paper addresses the motivation of model selection in knowledge discovery and related work, gives an overview of D2MS, and describes its solution to model selection and visualization. It then presents the usefulness of D2MS model selection in two case studies of discovering medical knowledge in hospital data—on meningitis and stomach cancer—using three data mining methods of decision trees, conceptual clustering, and rule induction.     

Marginalised Care: Migrant Workers Caring for Older People in Ireland

Older adult care in Ireland is a mix of public, private, voluntary and family provision. This model is characterised by deficient funding and support structures for both care recipients and carers, leading ultimately to fragmented service delivery, both in the community and in residential care. Against this backdrop, there has been a significant and rapid growth in the number of migrant registered nurses and care assistants providing care to Irish older people. With two potentially marginalised groups now at the centre of the caring relationship, questions arise regarding the sustainability of quality of care and quality of life for both providers and recipients of care. This research study draws on the perspectives of the older person, the migrant carer and the employer to develop an understanding of migrant worker care provision within the disadvantaged ageing sector in Ireland. The paper will frame migrant care workers’ experiences within the perspective of a marginalised sector, whose central consumers, older people, are not prioritised in policy or practice. Providing evidence of disadvantage for older adults and migrant carers, the research findings demonstrate that it is necessary to improve caring experiences and conditions for both groups if quality of care is to be enhanced.     

Delineation of House Design Guidelines for Fall Prevention of Older People

As the average life span becomes longer due to the development of medical technology and improving living conditions, interest in the quality of life in old age is on the increase. Health is central to a better quality of life, but the increasing healthcare costs incurred by older people are expected to become a heavy burden on society. Falls are the main external cause of unintentional injury among older people and are also responsible for a large proportion of healthcare costs. They occur frequently in the home and this has necessitated the improvement of the home environment in relation to fall prevention. Although there have been a considerable amount of studies concerning design features and guidelines, not enough research about the relationship between fall risks and the home environment has been conducted. In this context, the purpose of this study is to delineate house design guidelines for fall prevention in a comprehensive and systematic way. The main method of this study is a content analysis technique, and thirteen sources related to the environmental design for fall prevention and universal design were analysed through the content analysis. As a result, a total of 220 guidelines for fall prevention were identified and systematically arranged according to fall risk factors. These guidelines will help older people better perceive the danger of falls and will promote the improvement of housing conditions based on fall risk factors.
