"I wouldn't choose that key ring; it's not me": A design study of cherished possessions and the self

Copyright © 2016 ACM. We each possess certain objects that are dear to us for a variety of reasons. They can be sentimental to us, bring us delight through their use or empower us. Throughout our lives, we use these cherished possessions to reaffirm who we are, who we were and who we wish to become. To explore this, we conducted a design study that asked ten participants to consider their emotional attachment towards and the identity-relevance of cherished and newly introduced possessions. Participants were then asked to elaborate on their responses in interviews. Through a thematic analysis of these responses, we found that the emotional significance of possessions was reportedly influenced by both their relevance to selfhood and position within a life story. We use these findings to discuss how the design of new products and systems can promote emotional attachment by holding a multitude of emotionally significant meanings to their owners

Early Adversity and Late Life Employment History—A Sequence Analysis Based on SHARE

Numerous studies have linked poor socioeconomic circumstances during working life with early retirement. Few studies, however, have summarized entire patterns of employment histories and tested their links to social position at earlier stages of the life course. Therefore, this article summarizes types of late life employment histories and tests their associations with adversity both during childhood and early adulthood. We use data from the Survey of Health, Ageing and Retirement in Europe (SHARE) with retrospective life history data on 5,857 older men and women across 14 countries. Employment histories are studied with annual information on the employment situation between ages 50 and 70. To summarize employment histories we apply sequence analysis and group histories into 8 clusters with similar histories. Most of these clusters are dominated by full-time employees, with retirement before, at or after age 60. Additionally, we find clusters that are dominated by self-employment and comparatively late retirement. The remaining clusters are marked by part-time work, continuous domestic work, or discontinuous histories that include unemployment before retirement. Results of multinomial regressions (accounting for country affiliation and adjusted for potential confounders) show that early adversity is linked to full-time employment ending in retirement at age 60 or earlier and to discontinuous histories (in the case of women), but not to histories of self-employment. In sum, we find that histories of employees with early retirement and discontinuous histories are part of larger trajectories of disadvantage throughout the life course, supporting the idea of cumulative disadvantage in life course research

Oligon-coated contact lens case study: The efficacy of oligodynamic iontophoresis as a contact lens disinfection system as determined by FDA stand-alone protocol

Prototype contact lens cases have been prepared which are coated with an Oligon antimicrobial silicone formulation. The Oligon silicone coating incorporates a conductive additive, silver and platinum powder to set up an electrochemical system, that when contacted by chloride ions found in physiological saline, releases silver ions into the surrounding aqueous medium. Silver ions have been reported in the literature to be a potent antimicrobial agent, showing effectiveness against both gram-positive and gram-negative bacteria as well as yeasts and molds. This study was designed to study the effectiveness of Oligon coated contact lens cases against FDA (Food and Drug Administration) approved Stand Alone protocol for disinfecting contact lenses for the following organisms: Psuedomonas aeruginosa, Serratia marcenscens, Staphylococcus aureus, Candida albicans, and Fusarium solani. The results of the study conclude that the Oligon cases do not meet the 8 hour FDA stand alone criteria for any of the organisms tested, but with modification, may be an exciting new frontier for the future of contact lens disinfection

Designing meaningful products in the digital age: How users value their technological possessions

© 2019 Association for Computing Machinery. Devices such as phones, laptops and tablets have become central to the ways in which many people communicate with others, conduct business and spend their leisure time. This type of product uniquely contains both physical and digital components that affect how they are perceived and valued by users. This article investigates the nature of attachment in the context of technological possessions to better understand ways in which designers can create devices that are meaningful and kept for longer. Findings from our study of the self-reported associations and meaningfulness of technological possessions revealed that the digital contents of these possessions were often the primary source of meaning. Technological possessions were frequently perceived as systems of products rather than as singular devices. We identified several design opportunities for materialising the associations ascribed to the digital information contained within technological products to more meaningfully integrate their physical and digital components

Designing memory probes to inform dialogue

© 2017 ACM. To investigate the phenomenon that occurs during interactions between used objects and autobiographical memories, which are both ever-changing and imbedded with personal significance, an adapted probing method capable of managing these complex qualities is needed. This pictorial is our attempt to find a nuanced indication of how probes could go beyond common usage to facilitate complex felt experience, and how probes can be used in less prescriptive ways to instead promote reminiscent dialogues that are rich and open to interpretation for both participants and researchers. It illustrates our exploration into potential Memory Probes and how this might be done that reflects the value we see in creating restrictions or limitations in technologymediated interactions to encourage active participation by users in social acts such as memory creation and remembrance

Things that make us reminisce: Everyday memory cues as opportunities for interaction design

© Copyright 2015 ACM. Interactive devices can support personal remembering to benefit well-being. These designs require insight into what brings the past to mind, and how people relate to such cues. Prior work focused on mementos in the home; instead, this paper presents a diary and interview study of involuntary memory cueing in everyday life. Data was collected from fifteen adult individuals, using sentence completion diaries, combined with debriefing interviews. Qualitative analysis of the data showed that these participants were relying on everyday physical objects like food items for cueing memories during everyday life, locations and (repeated) activities, while digital items and photos were shown to be less frequent stimulants. Meaningful relations to memory cues can be partially explained from a memory cueing perspective. We discuss how design for remembering can benefit from our insights, through careful trade-offs in timing, exposure to cues, and supporting a process of personal attachment with items invoking memories

Negotiating claims of ‘whiteness’:Indo-European everyday experiences and ‘mixed-race’ identities in the Netherlands

This paper examines identity formations and negotiations among Indo-Europeans, and senses of ‘race’ in the postcolonial Netherlands. We do so by analysing daily practices of ‘being’, ‘feeling’ and ‘doing’ identities by second- and third-generation Indo-Europeans in the North-Eastern Netherlands. The paper contributes to ‘mixed-race’ literature by highlighting new, underexplored contexts in which ‘mixed-race’ identities are negotiated. We focus on practices, relations and transmissions across two generations and changing contexts within the Netherlands. Drawing on life story interviews, the narratives reveal how participants’ identities are politically and historically contingent, shaped by larger structures of racialized violence Indo-Europeans experienced in both the Dutch East Indies and the Netherlands. Identities are navigated in various ways with divergences and negotiations between self-identification, social imposition and familial and biological narrative

Making history: intentional capture of future memories

Lifelogging' technology makes it possible to amass digital data about every aspect of our everyday lives. Instead of focusing on such technical possibilities, here we investigate the way people compose long-term mnemonic representations of their lives. We asked 10 families to create a time capsule, a collection of objects used to trigger remembering in the distant future. Our results show that contrary to the lifelogging view, people are less interested in exhaustively digitally recording their past than in reconstructing it from carefully selected cues that are often physical objects. Time capsules were highly expressive and personal, many objects were made explicitly for inclusion, however with little object annotation. We use these findings to propose principles for designing technology that supports the active reconstruction of our future past

Neighbourhood walks as place-making in later life

For older people living in densely populated urban neighbourhoods, walking is an important mode of everyday mobility: it allows to engage in neighbourhood social life and can mitigate physiological decline, which is emphasised in healthy ageing discourses. However, walking is also a means through which meanings about the places of one's everyday life are (re)produced and, hence, contributes to feelings of illbeing and wellbeing. In this paper, we provide a phenomenological account of older adults' place-making practices through walking. In examining this topic, we draw on twelve walking interviews with older adults living independently in two urban neighbourhoods in the Netherlands. Our findings reveal that although our respondents developed a sense of 'insideness' through their spatial and social routes and routines, these same routes and routines also acted as exclusionary mechanisms. We argue that these 'meaningful movements', characterised by ambivalence, remain underexposed in healthy ageing discourses. Paying attention to these feelings and experiences would allow for a better understanding of the facilitators and impediments of walking in later life and its effect on social and emotional wellbeing. This paper concludes by providing implications for policy and planning practice in developing age-friendly and walkable neighbourhoods
