Increased longevity is the success story of 20th‐century biomedicine, together with improvements in general living conditions, but it brings great challenges. Although many individuals do undergo what might be termed ‘successful ageing’, this is not a universal experience, for with older age comes a range of age‐related diseases and degenerations that can diminish, if not destroy, quality of life for some older individuals. Biogerontology is the study of the biology of ageing, a normal process but one that has the potential to contribute to age‐related disease. Its goal is to extend the proportion of a life that is healthy, an outcome that is desirable both at an individual and a societal level. One of the great insights from the last decade or more of biogerontology is the realisation that the ageing process is not a fixed, unchangeable process. Rather, it is controlled by genes and is open to experimental interventions that extend healthy lifespan, in species from microbes to mice. These findings have produced a sea change in the way the biogerontological community views ageing: not as a fixed, ‘inevitable’ process, but one where rates of ageing vary enormously according to genotype, and can be readily changed by interventions. This makes the biological process of ageing an attractive target both to understand, and target, age‐related conditions.

The purpose of this paper is to describe the ageing behaviour of acrylate‐based resins for stereolithography (SL) technology using different test methods and to investigate these effects on polymers.

Controlling the polymer degradation requires an understanding of many different phenomena, including the different chemical mechanisms underlying structural changes in polymer macromolecules, the influences of polymer morphology, the complexities of oxidation chemistry and the complex reaction pathways of polymer additives. Several ageing characterization experiments are given.

The paper covers the ageing process analysis of acrylate‐based polymers. An overview of the ageing behaviour is given, along with the bandwidth of material characteristics for a prolonged lifetime of this material class.

For research and development in the field of rapid prototyping (RP) materials data about ageing behaviour and environmental effects are crucial. The authors show possible methods for measuring these effects and discuss the consequences in material research using a recently developed biocompatible SL resin as an example.

The study of the ageing behaviour of polymers is important for understanding their usability, storage, lifetime and recycling. The presented polymeric formulations are able to meet the growing demand for both soft and stiff manufacturing resin materials in the engineering and medical fields.

The analysis of the ageing behaviour of polymer materials is an important issue for engineering applications, recycling of post‐consumer plastic waste, as well as the use of polymers as biological implants and matrices for drug delivery and the lifetime of an article. The paper gives an overview of details involving ageing behaviour and their meaning for applications of acrylate‐based SL resins and is therefore of high importance to people with interest in long‐term behaviour and ageing of RP materials.

The purpose of this paper is to highlight the need to challenge ageism and to draw attention to how art, especially art activism, can challenge Ageism and bring about a new personal understanding of ageing.

This paper is a summary of personal reflections by the author.

The pervasive, ageist, stereotypical attitudes developed at an early age and the possible means to challenge and transform thinking through Art.

Artist and Arts organisations, their commissioners and funders could consider focussing upon ageing across the life course and commission and create work which challenges thinking and the status quo on ageing, reflecting society’s adjustment to an Ageing society.

Art and especially art activism could make a fundamental contribution to a raft of strategies to not only combat ageism but assist personal understanding of our ageing.

Currently there are relatively few artists and arts organisation focussing upon ageing across the life course. The paper states the view that such art activity could assist with new ways of understanding personal ageing and challenge ageist attitudes.

The purpose of this paper is to aim to characterise the knowledge management process of the ageing human capital, within the sectors of aeronautics and bio‐technologies in Canada.

The methodology consists of: cross‐search of literature towards the elaboration of a theoretical map; and collection of data involving semi‐directed interviews followed by a thematic and statistical analysis of the textual data.

Management's knowledge of social and relational knowledge, especially those of ageing workers, appears to be scarce, thus resulting in ageing workers being perceived as surpassed by technological and scientific progress. This conception deprives the company of an important source of knowledge capitalisation. A model relevant to the evaluation of company practices related to inter‐generational aspects of knowledge management should include six basic dimensions, namely: management philosophy (a managerial style favouring projections and proximities), strategic analysis (knowledge, memory and learning strategy), organisational analysis (information management system and knowledge creation process), operational analysis (places of socialisation), competencies (relational and communicational know‐how, individual memory and capacity of judgement), and the role of ageing personnel (activation of organisational and human resource networks).

Further validation is required across an enlarged population, with the aim of operationalising the observed concepts within a practical evaluation guide of company practices related to inter‐generational aspects of knowledge management.

By centering the analysis on highly qualified ageing individuals, the authors discerned a phenomenon showing that even within highly technological contexts knowledge management is far from systematically integrating those recognised a priori as carriers of knowledge.

In this paper we present preliminary findings from a study of the social, ethical and cultural aspects of ageing science and medicine. The paper draws on a collaborative, ongoing project between life scientists and sociologists, funded by the Economic and Social Research Council's (ESRC) New Dynamics of Ageing Programme1 and the ESRC Centre for the Economic and Social Aspects of Genomics2. The sociological element of this project involves participant observation and interviews with expert scientists who specialise in ageing and age‐related diseases, both in the UK and the US, as well as interviews with sceptics of ageing science and medicine. There has been much critique of how ageing science is anti‐ageing, reinforcing the ageism prevalent in Western culture. Our specific objective in this paper is to suggest how biogerontology can contribute to the social inclusion of older people, particularly in relation to health care. We discuss how agesim is endemic to some aspects of health care, and go on to show how the ways that biogerontology is reconceptualising what it is to age, and to be old, can help reinclude ageing and the aged in health‐care education, policy and practice.

Ageing has been known to affect the performance of lubricants. However, there is a lot of debate as to whether ageing is beneficial or detrimental to the wear performance of lubricants.

The purpose of this research is to evaluate the effect of ageing on the viscosity, total acid number and Fourier-transform infrared spectroscopy information of a series of lubricants. The tribological performance (friction and wear) of the aged lubricants is also studied, followed by X-ray photoelectron spectroscopy analysis on the selected post-test samples to study the tribochemical features of the tribofilm.

The results show that ageing has a different impact on lubricants and tribological performances based on the physical and chemical properties.

These findings will be compared with the research on the role of water in lubricant ageing (Part II of this study).

Preventative public health policies often rely on objective criteria to identify people in vulnerable situations. Age is one of the criteria when investigating the risk of malnutrition associated with ageing. By looking at changes in the food practices of individuals as they age, this study aims to seek to contribute to more precise targeting of older adults in view of the dynamic nature of ageing.

From a theoretical perspective, this research is based on the life course paradigm. Data were collected from 42 semi-structured interviews with retirees aged 60 and over.

The results show that some ageing events lead to immense reconfigurations of individuals’ lives, implying changes as prior food practices are extensively replaced by new ones (“rebuilding after a tsunami”). Other more diffuse and gradual effects of ageing lead to adaptations of previous food practices and, in a more localised way, areas that can be targeted by healthy eating campaigns (“plugging the gaps”). Lastly, this study shows that a normative perspective can help endorse a new social role (“getting into character”), and that relying on their human capital (“it’s a matter of perspective”) can help people cope with new age-related mindsets.

The sample did not include individuals with serious physical or mental health problems at the time of the interviews.

The study identifies social, biological and psychological events related to ageing that have an impact on food practices, as well as moments and milestones for developing public policy campaigns to promote healthy eating.

The study gives insights into the place of food in the process of coping with ageing, showing that food can be either a problem to solve or a resource to help cope with social or psychological imbalances. The holistic view adopted contributes to identifying other events that impact food practices (and consequently health) during the ageing process.

The purpose of this paper is to examine the gendered processes of ageing at work in Switzerland, a country already characterised by particularly high employment rates for seniors of both sexes, and where the notion of “active ageing” has recently appeared on the policy agenda. The study illustrates the mechanisms through which men and women accumulate dis-/advantage across the life course, and the influence that critical events in different life domains have on the conditions under which they prepare the transition to retirement.

The data used in the paper were collected with a mixed methods approach, including secondary statistical data analysis, expert interviews (with human resource and line managers), company case studies and 63-biographical interviews with male and female seniors employed in three different sectors (food distribution, health, transport) of the Swiss labour market. The interview guide covered issues relating directly to the employment histories and working conditions of the over 50s, but also enabled respondents to reflect on the influence of past or recent events in their private lives on their experiences of ageing at work (and vice versa).

The study shows that, in the Swiss context, ageing at work is a social experience, that is profoundly marked by societal-level normative “gender scripts” and by the gendered nature of major life-course transitions. However, rather than producing a clear distinction between the experiences of men on the one hand and women on the other, studying the accumulation of dis-/advantages (Dannefer, 2009) enables us to elaborate a more nuanced typology, mapping the Swiss experience of ageing at work according to four alternative ideal-type models: confident, resentful, determined and distressed.

In a context characterised by prolonged life expectancy and restricted welfare budgets, a clearer understanding of the conditions under which men and women make decisions about the continuation, interruption or adaptation of their professional activities (and care commitments) in the second half of their adult lives has clear implications, both for patterns of “active ageing” and for gender equality.

The paper sheds new light on the gendered variations in the experience of ageing at work in the Swiss context; it examines the implications of the dis-/advantages accumulated by different categories of men and women during various transitions in the employment and family spheres on their autonomy, well-being and satisfaction during this critical period of their adult lives.
