The longevity gender gap: are telomeres the explanation?

In this Perspective, we focus on the greater longevity of women as compared with men. We propose that, like aging itself, the longevity gender gap is exceedingly complex and argue that it may arise from sex-related hormonal differences and from somatic cell selection that favors cells more resistant to the ravages of time. We discuss the interplay of these factors with telomere biology and oxidative stress and suggest that an explanation for the longevity gender gap may arise from a better understanding of the differences in telomere dynamics between men and women.     

Controversy and Its Implications for the Practice of Contemporary Social Work in Intercountry Adoptions: A Korean–Australian Case Study

Abstract

Korean–Australian intercountry adoption has been practiced for 30 years. This longevity provides unique opportunities to develop critical perspectives on a complex, global practice. This paper presents understandings drawn from a study that explores Korean intercountry adoption using Actor Network Theory. It argues that the practice of intercountry adoption in Australia has been shaped by adoption-driven influences and characterised by controversy and competing discourses. It concludes that contemporary understandings necessitate a global, contextual, and critical view that is inclusive of emerging voices and alternate discourses. The challenge for practitioners and policy makers is to ensure the complex nature of the phenomenon is understood by all stakeholders. This will involve remaining child-focused, promoting multilevel interventions, incorporating research findings, and resisting wholly positive discourse that promotes singular perspectives. An awareness of how the internet is used to forge networks and promote discourses is crucial in ensuring multiple perspectives are considered in this contentious practice field.     

Allelic variation and human longevity

Human longevity is a complex phenotype with a strong genetic contribution. The search for allelic variation that impacts on longevity often involves population-based association studies of long-lived individuals (centenarians and nonagenarians) and younger controls. A major methodological problem with this approach is that the cases and controls in these experiments are often born several generations apart. The inherent absence of "age matching" can lead to serious misinterpretations. For example, allele frequency differences between long-lived individuals and younger controls may not reflect an effect on longevity but rather a change in population structure over time or different gene-environment interactions across generations.     

LONGEVITY AND PUBLIC OLD-AGE PENSIONS

Using an overlapping generations model with endogenous but uncertain longevity, this article analyzes the effects of public old-age pensions on longevity choice and capital accumulation. When agents are not altruistic, increases in old-age pensions are longevity-neutral for golden rule economies and longevity-decreasing if interest rates exceed population growth, and saving effects are strictly negative. When agents are altruistic, longevity is independent of old-age pensions regardless of the interest rate–population growth relation. On the other hand, the longevity effect of a price subsidy on longevity extending expenditures or an advance in longevity extending technology is positive.(JEL H5 , J1 )     

Social movement coalitions: Formation,longevity, and success

Social movements rely on coalitions to help mobilize the mass numbers of people necessary for success. In this article, we review the literature on social movement coalition formation, longevity, and success. We identify five factors critical to coalition formation: (a) social ties; (b) conducive organizational structures; (c) ideology, culture, and identity; (d) the institutional environment; and (e) resources. Next, we explore the extent to which coalition survival is influenced by these same factors and argue that emergent properties of the coalition, such as commitment and trust, also facilitate longevity. Our review of the literature reveals that two factors specific to coalitions influence their success: coalition form and the nature of institutional targets. Interaction, communication technology, and the availability of physical and virtual spaces that facilitate communication are themes that run throughout our discussion, as they undergird many of the elements that shape coalition formation and survival. We conclude by evaluating the state of the research area and suggesting directions for further research.     

Change resistance moderates existence and longevity biases

Evidence has been found for existence and longevity biases—inferences of goodness from prevalence or longevity. We argue these biases actually emerge among change-resisting individuals. Our evidence suggests change-accepting individuals can even demonstrate a reversal of these biases. In two studies, change-resisting individuals’ attitudes were suggestive of existence and longevity biases while change-accepting individuals significantly reversed this pattern by evaluating long-standing or prevalent objects less favorably. Finally, we reanalyzed data from the existence and longevity biases literature previously reported in Social Influence. We found Americans identifying as more Republican—thus theorized as more change-resisting—were those who favored a long-standing practice. Altogether, we argue that existence and longevity biases emerge depending on individuals’ change resistance, indicating an important theoretical expansion.     

Care managers’ perceptions of eHomecare: a qualitative interview study

To implement information and communication technology (ICT) in elderly care can be a challenge for healthcare organisations. In Sweden, care managers (CMs) are responsible for offering ICT as a new part of homecare, i.e. eHomecare. The aim of this study was to focus on CMs’ perspectives and describe their perceptions of eHomecare. The study has a qualitative approach. Semi-structured interviews based on vignettes were conducted with 12 CMs in a medium-sized municipality in central Sweden. Data were analysed using qualitative analysis. The findings showed that CMs are influenced by surrounding organisations and relatives in their decision to grant eHomecare. There were also difficulties in CMs’ management of eHomecare. Furthermore, eHomecare was perceived to improve the quality of everyday life for older. It is understood that the management of eHomecare is a challenging task for CMs and a complex mission. Interactions among CMs, relatives, care providers, and other factors as for example CMs’ own attitudes have an impact on CMs’ decisions.     

Vital connections

Scientists are currently exploring the structure and behavior of complex biological systems, which consist of networks of interacting entities. A recent paper in Proceedings of the Royal Society of London Series B Biological Sciences describes the distinctive characteristics of aging-related proteins in the yeast protein-protein interaction network. In this Perspective, I discuss the implications of these findings for longevity research.     

Introduction: Human Longevity,Utopia, and Solidarity

Biomedical and geriatric technologies are having major impacts on the development and management of human longevity. Our contention in this special issue is that longevity should be considered as a point of departure for new forms of politics in which social sciences, in particular sociology and politics, can play an important role. In this introduction, we argue that emerging consumer markets in biomedicine are incrementally redefining the relationship between old age and society. Techno‐economic transformations are creating new sites of vulnerability that are masked by medical utopias of good health and “living forever.” In this context, it is unlikely that such technologies will be able to overcome inequalities in distribution and may well exacerbate various forms of injustice. By drawing on notions of institutional precariousness and scarcity, we conclude that to maintain any degree of social solidarity, increasing longevity will force the emergence of a “sociology of limits.”     

Consistency between Sentiments and Acts

Consistency is a concept central to most social science research. In this paper we challenge the typical simplistic assumptions of consistency between words and deeds. We contend that consistency is a complex concept which must be studied through a situated approach. By employing the literature on motives in sociology and communication, we consider the means by which actors construct consistency and inconsistency in social interaction. Central to this process are anticipated, or actual, calls for accountability. Consistency and inconsistency become issues when we attempt to hold self, or other, accountable.     

Diversity Management in der Organisationsberatung

Each individual is (in some respect) similar to many, few or no other person. Diversity deals with this individuality i.e. with differences and similarities between people. In the light of internationalization, diversity has become a main interest area of organizations. Diversity Management is a strategic approach which uses individual abilities, experiences, competencies and qualifications as special success factors in companies. It is however, for many companies and managers, a real challenge to overcome mono-cultural thinking, prejudices and the reluctance to change. They need help from specialized diversity consultants.     

Epigenetic regulation of aging in honeybee workers

Aging and longevity are complex life history traits that are influenced by both genes and environment and exhibit significant phenotypic plasticity in a broad range of organisms. A striking example of this plasticity is seen in social insects, such as ants and bees, where different castes can have very different life spans. In particular, the honeybee worker offers an intriguing example of environmental control on aging rate, because workers are conditionally sterile and display very different aging patterns depending on which temporal caste they belong to (hive bee, forager, or a long-lived caste capable of surviving for several months on honey alone). The ubiquitous yolk protein vitellogenin appears to play a key role in the regulatory circuitry that controls this variation. Here we outline the current understanding of the relation between vitellogenin and somatic maintenance in honeybee workers, and how this relation can be understood in a life history context.     

Subfield history: use of model organisms in the search for human aging genes

The National Institute on Aging (NIA) started a program in 1993 to identify genes involved in the regulation of longevity in a variety of species, including yeast, nematodes, fruit flies, and mice. The initial success of this program has attracted the interest of many investigators working with these organisms. Of primary interest are single-gene mutants that have identified genes and processes involved in longevity regulation across species. These processes include the insulin-like signaling pathway, stress resistance, and most recently, chromosome and nuclear architecture. Mutations in genes that regulate these processes indirectly are also being identified in this program. The ultimate goal of this program is to extend these results to humans to identify the major biological risk factors for age-related decline of function in human physiological systems.     

Common factors are not islands--they work through models: a response to Sexton, Ridley, and Kleiner

In this article, we respond to Sexton, Ridley, and Kleiner (this issue) from three different perspectives. First, we discuss their criticisms as rooted in a portrait of common factors to which we do not subscribe. Second, we discuss points of agreement and partial agreement between our two articles. Finally, we discuss our areas of clear disagreement with their points of view. In these areas of disagreement we put forth the common factors approach as an empirically supported lens; we discuss the influence of investigator allegiance on the specificity conclusion; and we challenge the idea that the common factors lens is simple. In conclusion, we illustrate how common factors work through a credible therapy model using functional family therapy as an example.     

Social Work Student Self-Care and Academic Stress

The purpose of the present study was to investigate the relationship between self-care and academic stress in the hope that training social work students to practice self-care will start them on the right path to academic success and career longevity. The study surveyed 90 BASW and MSW students using the Academic Stress Scale. Students who practiced daily self-care had lower academic stress. In addition, with each year of progression through the program, students experienced minimally less academic stress. The type of self-care practiced was not a factor. Social work programs can be encouraged to teach self-care. Self-care theory and domains are also reviewed. More studies are needed to examine other factors that might reduce academic stress.     

Exploring the development of meaningful work for children and youth in Western contexts

Through a literature review, this paper explores current issues influencing the transition to meaningful adult work for youth living in Western contexts. Historical and contemporary perspectives of children's work are discussed. With the current emphasis on finding meaningful work, youth face greater challenges because the transition to adult work is more complex, offering additional options without structured pathways. Today's youth are required to invest more energy into developing the skills and self-knowledge needed to make meaningful decisions about future work. Given this challenge, a number of key factors associated with the successful transition to adult work are identified and discussed including social origin, time orientation, parental influence, work experience, and participation in structured leisure pursuits. For each key factor, implications for practice are offered to help parents, teachers, youth workers, and other significant adults foster interactions and experiences that may assist today's youth in successfully transitioning to meaningful adult work.     

Cognitive Ability and Post-Retirement Asset Decumulation

Post-retirement asset decumulation decisions are complex and may be affected by cognitive abilities. Estimating uncertainties such as life expectancy and medical costs, and incorporating them effectively into decumulation decisions may be especially difficult as retirees face age-related changes in cognition. This may result in rates of decumulation that are contradictory to the goals that motivated accumulation, leading to potentially large utility losses. We investigated the relevance of cognitive ability to asset decumulation decisions within our sample. We found that cognitive ability was a significant predictor of the rate of asset decumulation, and that those with lower levels of cognitive ability were decumulating at a significantly lower rate. We also showed that the level of cognitive ability influenced the effects of expected longevity, market returns, and medical costs. While the estimates for these factors were consistent between those with high and low cognitive ability, there were significant differences in how the estimates were incorporated into the asset decumulation decisions of the two groups.     

Life at Age 100: An International Research Agenda for Centenarian Studies

ABSTRACT

Living a long life is desired by many individuals, and this dream is likely to become reality in more and more industrialized societies. During the past 3 decades, the number of very old individuals has increased significantly, creating a global demographic challenge with consequences at the individual, family, and societal levels. Yet, life in very old age is still poorly understood in terms of its unique characteristics and challenges. Besides specific content areas, very old age represents an understudied field of research. This lack of knowledge may be one reason that the very old also are an underserved population. This special issue introduces an international network of three centenarian studies that describe and compare the life circumstances and characteristics of centenarians across Germany, Portugal, and the United States. Our parallel studies comprehensively assess centenarians’ physical, cognitive, social, and psychological functioning to create a knowledge base regarding their capacities and needs. A specific focus lies in the investigation of psychological aspects, social resources, and societal/cultural contexts, factors that may contribute to longevity and successful aging. Determining key characteristics of this very old population and investigating similarities and differences across countries is timely and urgent, both from an applied and a policy standpoint.
