Abstract (sommario):

AbstractFor the past two decades the issue of housing for the aged has caught the attention of many in the private as well as in the public sectors, and attempts have been made to improve the situation. If the problem persists today, gerontologists, among others, should be called to account, since they were instrumental in the formulation of many of the interventions. The problem has been approached generally in terms of adaptation to aging and adaptation to the environment. The ecological models currently used agree that happiness can be found at different states of equilibrium between the person and the environment and that the elderly arrive at this state of equilibrium through a special “docility” towards the environment; a “docility” which would be linked to aging. However, this docility would appear to be historically and socially contingent rather than being “natural”. It is thus important to explain the social production of old age and the docility which is tied to it.

Abstract (sommario):

The communication ecology model of successful aging (CEMSA) as a part of aging studies from a communication perspective was replicated in the Indonesian context. The CEMSA provided a specific perspective from communication scholars about the successful aging process. The study of CEMSA has grown significantly to demonstrate the importance of the interactive-communication process to propagate and enhance aging studies. However, there has been no specific aging study from a communication perspective, especially from communication scholars in the Indonesian context. This study applied all concepts, variables, measurements, and analyses from the replicated study. The result showed that seven domains of communication about aging may be relevant to predict successful aging from a negative effect and positive effect, and efficacy toward aging. The model showed that the uncertainty and combination of a negative and positive effect in seven domains of communication about aging could construct the efficacy and success of the aging process. The model with seven domains of communication about aging could be proved while the data were gathered not by self-report.

Abstract (sommario):

Abstract Substantial advances have been made in understanding both evolutionary and mechanistic aspects of biological ageing, but the two areas remain poorly integrated. I suggest that a greater emphasis on ecology can help to integrate evolutionary and mechanistic research on ageing, by providing insight into the interface between biological mechanisms and the environments in which they evolved. Among the most salient aspects of the environment relevant to ageing is nutrition. And yet in the bulk of ageing research nutrition is coarsely represented as dietary restriction or caloric restriction, without consideration for which components of the diet or which energetic substrates are driving the observed effects. I show how a method developed in nutritional ecology, called the nutritional geometry framework, can help to understand the nutritional interactions of animals with their environments, by explicitly distinguishing the roles of calories, individual nutrients and nutrient balance.

Abstract (sommario):

As animals age, they are expected to invest successively more energy in reproduction as they have fewer subsequent chances to reproduce (the “restraint” hypothesis). Conversely, the oldest animals may show restraint in reproduction because even a small increase in energy expended during reproduction may lead to death. Alternatively, both young and very old animals may lack the ability to maintain high levels of energy expenditure (the “constraint” hypothesis), leading to reduced reproductive success. Many studies have observed an increase in reproductive success with age followed by a reduction at the end of life, but fewer studies have examined the proximate mechanisms, which provide a context for understanding ultimate causes. I examined over 30 behavioural and physiological metrics of aging in two species of free-living long-lived seabirds (thick-billed murres Uria lomvia and black-legged kittiwakes Rissa tridactyla) and a short-lived passerine (tree swallows Tachycineta bicolor). For all species, reproductive success was high at intermediate ages. In support of the “restraint” hypothesis, when birds were stressed glucocorticoid hormones, which direct energy away from reproduction and towards survival, were higher in young birds (swallows) and both young and very old birds (kittiwakes and murres). When birds were handicapped older birds expended more energy. When challenged exogenously, there was no change in hormone levels with age, implying that they were “choosing” to be restrained. Resting metabolic rate (RMR) declined linearly with age in both seabird species. T3, which I show is indicative of RMR in birds, also declined with age, demonstrating that the reduction in metabolism was strategic and not due to changing body composition. In contrast, daily energy expenditure in both seabird species during breeding was constant with age while antioxidant capacity became elevated during middle age, and further increased with age. Several measures of behavioural performance did not vary with age. I conclude that hormonal cues lead to greater investment in adult’s energy stores over its offspring’s energy reserves (restraint hypothesis) at the start of life. At the end of life, both hypotheses were supported; energy expenditure was constrained by senescence, leading to increased restraint in investing additionally in offspring.

Abstract (sommario):

Aging is a degenerative process characterized by a decline in physiological functions and cellular activities. Environmental and pharmacological interventions affecting longevity pathways have been extensively studied in model organisms. This study investigated the effect of chronic mild intermittent hypoxia (4 mg O2/L) or mild mitochondrial uncoupling with three doses of 0 (control), 0.1, 1, and 5 μM of 2,4-Dinitrophenol (DNP), on life history and gene expression in four clones of Daphnia magna. Interestingly, clones from intermittent ponds displayed better tolerance to hypoxia and DNP. Although neither treatments extended longevity, hypoxia increased fecundity and body size, and decreased food consumption and respiration rate. We uncovered 12 candidate genes that were differentially expressed in hypoxia-tolerant and sensitive clones in response to hypoxia. Unexpectedly, DNP increased fecundity and mitochondrial membrane potential without affecting food intake. This work opens up an opportunity for genomic determination of the potentially important phenotypes in a model organism.

Abstract (sommario):

In recent years, tremendous growth in the older adult population has prompted the US Federal government along with state governments to fund programs and organizational structures that can help meet the needs of older adults. Further, organizations such as the National Council on Aging, as well as the American Association of Retired Persons (AARP), and nonprofits such as the United Way also partner in these efforts. This project seeks to analyze the content of American state and federal policy as well as nonprofit programs in order to identify the policy priorities that are currently being supported. Do current policy efforts promote “aging in place” strategies as a way to maintain quality of life and older adult health? An analysis of public policies and nonprofit program structures in the United States since 2000 will help to identify policy priorities that impact aging adults, and will hopefully pave the way to prepare our society for further actions and needs in order to continue to serve them in the next several decades.

Abstract (sommario):

Ageing women have so often been represented in government policy rhetoric, gerontology literatures and journalistic discourse as the genderless, powerless and passive objects of welfare and services;, by and large, as a social problem that needs to be monitored and managed. Taking a cultural research approach, this thesis explores ageing women’s actual practices in Hong Kong social movements and aims to rerepresent ageing women as active social agents capable of generating multiple “tactical identities” enabling them to participate in and interact with an environment that poses concrete challenges to their participation. In filling the gap between research on social movements and in social gerontology, both massively studied areas but ones whose mutual interactions are rare, this thesis reviews the social participations of three women at their late 60s and early 70s, who have been actively involved around issues of involuntary removal in public housing, and in health care and rent issues. The research explores how ageing women have used the notions of “Old Hong Kong” and “Old residents” - a rhetoric long bound up with their life histories in Hong Kong—to create a ‘mask of ageing’ in negotiation and interaction with the authorities, with neighbours, their community and, most importantly, their children. On the other hand, by acting as mothers, as grandmothers and as the “po po” (older woman in Cantonese) living next door, ageing women in effect compose collectives and form networks in their community to support their independent mode of living. The thesis argues that a new politics of ageing which addresses the everyday realities of ageing women’s lives is essential if we are to offer an alternative interpretation of their ageing experiences.

Abstract (sommario):

Climate change will lead to higher temperatures and longer summers in the future, which will likely influence the growing season of fish living in temperate lakes. The warm summer of 2018 in Sweden matches prognoses for normal summers at the end of the century and can thus be used to investigate the effect of temperature related factors on fish growth. In this study I used back-calculation of the growth of roach (Rutilus rutilus) caught in Lake Tåkern, Sweden, to find differences in growth during 2018’s hot summer versus the period 2012-2017. I compared growth during these years with results from a similar study from Lake Tåkern in 1978. For this comparison I used 1977 as a representative year for the 1970’s. I applied sclerochronology to the scales to determine age and growth. The results show that growth in terms of length increment was faster in 2018 than in 2012 – 2016. The results indicate that 2018 had an effect on the whole roach population, since significant differences were found across age groups. Additional comparisons between 1977 and 2018 showed no significant difference. Differences in roach growth rate between 2012-2018 could be caused by the differences in mean temperature during the roaches growing season, since 2018 was abnormally warm, and the difference between 1997 and 2018 could be attributed to 1977’s fish death. This means that if the pattern of climate change continues, roach growth rates will increase in the future regardless of age group.

Rick J. Scheidt
Currently in the United States there are 2.7 million grandparent caregivers caring for 5.4 million grandchildren, with 883,386 of these grandparents caring for their grandchildren without any assistance from the child’s biological parent. These grandparents have unique needs and require support services that understand and recognize those needs. However, many of the resources currently available are not designed to assist this population. This report explores many of the issues grandparents face when taking over as the primary caregiver for their grandchild. Specifically this report highlights the financial, legal, and medical issues, as well as the need for respite care and housing. These particular issues were selected because they are commonly cited as difficult areas to navigate for grandparent caregivers, and also because there are crucial resources in each of these areas that allow grandparents to successfully raise their grandchild. Without these tools, the process of raising the grandchild can prove extremely difficult for grandparents, which can have negative consequences on the grandchildren. In addition it offers suggestions for grandparents seeking assistance regarding these issues, also providing several resources. This report also offers guidance for grandparent caregiver advocates and encourages future research and scholarship to explore programs assisting this population.

Abstract (sommario):

AbstractIn this part we focus on the domain of exclusion from social relations where social relations can be defined as comprising social resources, social connections and social networks. Other types of social engagement with formal civic, political and voluntary groups and organisations are not included in this part, but instead are incorporated in the domain of civic exclusion [see Part VI]. Theorising on exclusion from social relations is facilitated by the ROSEnet Cost Action, which brought together experts in the field and led to the publication of a critical review and development of a conceptual model of exclusion from social relations for older people (Burholt et al. 2019). The model captured the complexity of exclusion from social relations through a subjective interpretation of the literature and took into account the inter-relationships between systems in the critical human ecology framework (Fig. 6.1). The synthesis of the findings was endorsed by the working group on social relations comprising 45 members from 25 countries. The purpose of this introduction is to outline what exclusion from social relations involves, and to frame the three contributions within this part in the broader research debates and scholarship on this topic.

AbstractThis chapter fits Goal 15 of the SDGs and analyzes the protection and sustainable use of territorial ecosystems in Japan, focusing on sustainable agricultureand forestry. The beautiful natural landscape and pristine nature in Japan are protected in nature parks. After the Earth Summit in 1992, the government committed to protecting socio-ecological landscapes referred to as “satoyama.” They include farmland, pastureland, and forests for logging. They are deteriorating because the population of farmers and forestry workers is declining and aging. The Natural Parks Act introduced a scheme to ensure that environmental NGOs maintain these areas on behalf of the farmers and forest workers. Modernization of agriculture has caused the loss of biodiversity in farmlands. Restoration projects have been implemented to restore biodiversity in rural areas. To reduce farmland abandonment, the government grants subsidies to help encourage eco-friendly agriculture. The government is encouraging active farmers to scale-up agricultural management to be competitive in the marketplace. Solar sharing is one way to help farmers. Ecologically sustainable development is thus interwoven with social and economic factors.

AbstractIn this chapter, we explore how applying a feminist political ecology (FPE) lens to ageing shows how ageing experiences are relational and dynamic processes of embodying everyday practices and ethics of care. We apply writings on post-capitalist community economies and rupturist gerontology and FPE intersectional thinking and link them to two studies of ageing in Japan and Uruguay. We analyse ageing as part of dynamic socionatural relations and the ethics of care including the agentic roles played by miso, machines, fungus, climate, and politics. Our chapter shows how the role played by socionatural relations in ageing experiences demands more careful attention.

Abstract (sommario):

The term smart city was first used in the nineties of the 20th century, and then the focus was on the application of innovative technologies, as part of modern infrastructure within cities. Nowadays, a smart city means an instrumented, interconnected and intelligent city. European cities are not sufficiently tolerable, inclusive or productive for the needs of the modern age. Smart cities of the present and future should improve the area of social life, but also the organization of public transport, for example. In addition, the policy of developing smart cities should prevent difficulties, rather than finding ways to solve them. The aging of the European population, the integration of migrants, social exclusion or the unsustainability of the natural environment, as well as unemployment, delinquency and a weak local economy, are seen as pressing difficulties. Human or social ecology describes the relationships between people who share the same habitat or local territory and these relationships are clearly related to the character of the territory itself. It is, in fact, learning about social structure in relation to the local environment. So sociologists, in the later years of the 20th century, included ecology in studies of social development or the evolution of human institutions and widely incorporated that concept from the domain of natural sciences into the domain of social sciences. The development of smart cities, by itself, will not eliminate delinquency. Therefore, it is necessary to consider a special concept of crime prevention, which would primarily refer to the prevention of criminal behavior within the community, within the city.

Abstract (sommario):

Abstract Electronic parts may be subjected to continuous activity at high temperatures as well as high strain-rate loads in the oil exploration industry, military, automotive, avionics, and space applications, and parts may be stored in non-climate-controlled enclosures prior to deployment. Material properties evolve at even moderate temperatures after a long period of storage, according to previous studies on undoped SAC alloys. To reduce the aging effects, a number of alloy formulations have been proposed. Data on the mechanical properties of lead-free solder alloys used for interconnection in electronic packaging at high strain rates and high storage temperatures is very important for design optimization of electronic package sustainability at extreme temperatures, since SAC soldiers have shown degradation of mechanical properties after prolonged exposure to storage temperature. The use of dopants in SAC solder has been proposed as a solution to minimize degradation. In this study, After keeping the samples in storage at 50°C for 1–8 months, a doped SAC solder called SAC-R (Ecolloy) was subjected to high strain rate testing. Uniaxial impact hammer tensile tests were conducted on samples with no aging and samples that had been aged for up to 8 months to assess the mechanical properties of SAC-R at high and low operating temperatures ranging from −65°C to 200°C and the Mechanical properties has been compared with an undoped solder SAC 105. The constants for the Anand Visco-Plasticity model were calculated using the material data for SAC-R. By comparing model predictions of the uniaxial tensile test with experimental results, the model’s ability to reflect material constitutive behavior has been quantified.
