Aging as intracohort differentiation: Accentuation,the Matthew effect,and the life course

Recent contributions of sociologists and others have brought a new awareness and new theoretical understanding of the extent to which human aging and life-course patterns are shaped by social conditions and influenced by social change. Yet the potential of many social processes to account for individual aging patterns remains untapped, because research and theory have focused heavily upon comparisons between cohorts rather than the internal differentiation of cohorts. This paper shows that focusing upon intracohort differentiation over the life course leads to a mobilization of sociological findings whose age-related implications have not been exploited. Using the phenomenon of aged heterogeneity as an illustrative case, it is suggested that intracohort differentiation—operating through macro-level, organizational, and micro-level processes—can explain significant phenomena of aging previously neglected by theory, or else assumed to be psychological in origin. These processes specify Merton's Matthew effect. Implications for biological aging and for research are briefly discussed.     

Successful aging: choosing wisdom over despair

This article defines wisdom and despair as choices for cognitively intact older adults. Some individuals are able to integrate the conditions of old age while others respond in ways that inhibit effective integration. The conscious aging theory, as well as Erikson's developmental theory regarding achievement of integrity/wisdom, provides a theoretical basis for exploration of this topic. Constructs of personality, including self-concept, self-acceptance, destiny control, interiority, rigidity, and flexibility, are described. Finally, guidelines for nurses working with older adults who are facing this developmental stage of life are provided.     

Autopoiesis and socialization: on Luhmann's reconceptualization of communication and socialization

In 1984, Niklas Luhmann published Soziale Systeme in which he applies the idea of autopoiesis (= self-production) to social systems. Abstracted from its biological connotations, the concept of autopoiesis leads to a sharp distinction between different kinds of autopoietic organization, i.e. between life, consciousness and communication. According to Luhmann, the relationship between social systems and human beings cannot be adequately analysed except by taking into account that they are environments for one another. If this theoretical background is accepted, the concepts and theory of socialization need to be revised. Luhmann takes issues with classical notions such as internalization, inculcation, or 'socialization to the grounds of consensus' (Talcott Parsons). After a historical overview of social systems research and general systems theory, it is indicated how communications trigger further communications and realize the autopoiesis of social systems. In the second part of the article, the distinction between social systems and psychic systems is used to discuss issues crucial to socialization theory. Both a revision of the concept of socialization, and lines for an empirical research programme are proposed in accordance with Luhmann's theory of social systems.     

Intergenerational solidarity: An attachment perspective

The concept of intergenerational solidarity between parents and children has been addressed within sociology using an increasing number of dimensions, some overlapping with phenomena studied in attachment theoretical research within psychology. Attachment theory is an important candidate for cross-disciplinary research into intergenerational solidarity, because it identifies causal processes within individuals as well as relationships. Due to its developmental nature the attachment theory is also highly relevant to life-cycle issues surrounding intergenerational solidarity. In this theoretical review, the basic dimensions which attachment theory uses to describe relationships are articulated with reference to pertinent issues under the rubric of intergenerational solidarity. Examples are provided to illustrate how at the cross-section of psychology and sociology these dimensions (direction, quality, and penetration) can be used for answering questions (patterns of exchange, tensions, ambivalence) about relationships between adult children and aging parents.     

Theories of Aging and Social Work Practice with Sensitivity to Diversity

Abstract

Aging experiences are multidimensional, and social workers need to know theoretical perspectives on aging which are useful in understanding the diversity of experiences of individuals in later adulthood. This article describes and discusses four theoretical perspectives on aging which are not usually presented in Human Behavior and the Social Environment textbooks but which contribute to understanding of diversity in later adulthood: Atchley's continuity theory; Fisher's age-independent periods; Stoller and Gibson's perspectives on gender, race and ethnicity, class, and the life course; and Friend's theory of successful aging of gay men and lesbian women.     

Nitric oxide and oxidative stress in cardiovascular aging

The long-standing free radical theory of aging, which attributes cellular pathology to the relentless accumulation of reactive oxygen species (ROS), remains attractive but controversial. Emerging insights into the molecular interactions between ROS and reactive nitrogen species (RNS) such as nitric oxide suggest that, in biological systems, one effect of increased ROS is the disruption of protein S-nitrosylation, a ubiquitous posttranslational modification system. In this way, ROS may not only damage cells but also disrupt widespread signaling pathways. Here, we discuss this phenomenon in the context of the cardiovascular system and propose that ideas regarding oxidative stress and aging need to be reevaluated to take account of the balance between oxidative and nitrosative stress.     

Acoustic correlates of speaker sex identification: Implications for the transsexual voice

As sex research has expanded, a plethora of similar but unconnected theoretical constructs has arisen. Recently, Byrne (1977) and colleagues have developed a conceptual framework which establishes a set of relationships between erotic stimuli, theoretical constructs, and sexual behavior. One main component of this theory is a type of emotional response to sexual stimuli labelled erotophobia‐erotophilia as measured by the Sexual Opinion Survey. Research on this theory indicates that its constructs are important for sex therapists and researchers. Based on previous studies establishing the reliability and validity of the Sexual Opinion Survey (SOS), a study was conducted in which the Survey was administered to 327 adults. Responses to the SOS were used to develop a set of standard scores, percentiles, and preliminary norms to facilitate use of the Survey in clinical practice and research. A principal components analysis of the SOS also was conducted, yielding three reliable and interpretable factors. Analysis of various weighting systems suggested that factor scores derived from the SOS could be calculated reliably simply by addition or subtraction of item scores. Application of the SOS and Byrne's theory for clinical practice, case studies, and clinical research is encouraged as a means of extending the theory and as a way of helping relate elements of sexuality to ongoing social behavior.     

Age and subcultural differences on personal and general beliefs about memory

This study examined age and cultural differences on both personal and general beliefs about memory by comparing three age groups within two subcultures belonging to the same country: Milanese and Sardinian. Two innovative instruments on general and personal beliefs with graphic-rating-scale format (General Beliefs about Memory Instrument and Personal Beliefs about Memory Instrument) and a memory task (recall of 40 words) were administrated to participants. Sardinians held more positive attitudes about the effects of aging on memory reporting a later onset of declining memory ability and control over memory across the life span. They were also more optimistic in rating their global memory efficacy, control, and retrospective change. The two subcultural groups differed in terms of memory performance, with Sardinian individuals outperforming the Milanese. Findings are discussed in relation to the view of aging in different subcultural contexts.     

Aging and Family Life: A Decade Review

In this review, we summarize and critically evaluate the major empirical, conceptual, and theoretical directions that studies of aging families have taken during the first decade of the 21st century. The field has benefited from an expanded perspective based on four overarching themes: (a) complexity in emotional relations, (b) diversity in family structures and households, (c) interdependence of family roles and functions, and (d) patterns and outcomes of caregiving. Although research on aging families has advanced theory and applied innovative statistical techniques, the literature has fallen short in fully representing diverse populations and in applying the broadest set of methodological tools available. We discuss these and other frontier areas of scholarship in light of the aging of baby boomers and their families.     

Extending the Symbolic Interactionist Theory of Interaction Processes: A Conceptual Outline

This article outlines the elements of a more robust symbolic interactionist theory of interpersonal processes. I argue that George Herbert Mead's conceptualization of interaction processes can be extended to explain not only micro‐level social processes but also key elements of meso‐ and macro‐level dynamics. By expanding Mead's and more recent symbolic interactionist theorizing, and incorporating key ideas from other theoretical traditions outside symbolic interactionism proper, it becomes possible to develop a theory of interaction that fills in important conceptual gaps in theories on the dynamics of micro‐, meso‐, and macro‐level social phenomena.     

Perspectives on the Biodemography of Longevity and Aging

Biodemography is a timely and exciting area of research that has been emerging over the past 15–20 years and might arguably be the most quickly growing area of demography. From the perspective of longevity and aging, questions arise that touch on the biological foundation of aging. With a focus on mortality, this article offers a perspective on recent developments in evolutionary biodemography. These include new theories, methods, and data that have resulted in striking new findings on the diversity of life courses (including the option of escape from aging for some species) that is licensed by nature across the tree of life. As the human life course is rapidly changing due to unimpeded population aging, advances in development of biodemographic theories, methods and databases may prove useful and inspire advances in sociology.     

Redefining generativity: Through life course and pragmatist lenses

Scholars in diverse disciplines have studied and used the concept of generativity, originally introduced in psychology as a midlife development task. However, a review of this multidisciplinary literature in generativity revealed several issues—the lack of a cohesive conceptual definition, incompatibility between a conceptual definition and measurements, and varying applications of the model, necessitating a new direction for further conceptual development. Interdisciplinary theoretical insight and empirical evidence collectively suggest that generativity as a targeted midlife task may no longer be sufficient for explaining a life course pattern of generative concerns, commitment, and actions. Given the current trend of population aging, it is especially important to understand better the phenomenon of generativity during the later stages of the life course. The current article offers a new definition for generativity applicable to people across the life course and develops an expanded generativity model, which considers social context and bears practical implications for well‐being. Major implications for future research consist of eliminating the implicit age bias in the conception of generativity and as informed by the pragmatist philosophical perspective, linking generativity to diverse personal experiences and growth rather than mortality.     

Alternative Perspectives on Community Impacting: Toward Complementary Theory and Application

Community impact analysis has been limited in applied effectiveness and sociological contribution because of its primary reliance on an ecological system paradigm and the conservative ideology imbedded therein. It is argued that the quality of community impact analysis and similar social change work would be improved by increased concern with matters of theory. Specifically, improvements can come from: (1) use and further development of alternate sociological perspectives appropriate to the impacting topic, especially those perspectives that deal with community and adaptive processes; and (2) empirical determination of the extent to which various theoretical perspectives fit conditions of specific community cases. The concerns of critical and interactionist theory are discussed as alternatives to the dominant structural-functional perspective, and a case is made for blending perspectives consistent with themes of "general systems" theory. This blending incorporates structural concerns, but offers more complete guidance by emphasizing relevant process considerations. Aspects of the "dramaturgical" analogy, applied more broadly than usual, illustrate abstract points in the complementarity of the several theories.     

PREDICTING MORTALITY AMONG INDEPENDENTLY LIVING RURAL ELDERLY:

The problem of predicting mortality among rural elderly (65 years and older) living independently is examined using 20-year panel data derived from a random multistage cluster sample. Fifteen independent variables, including social networks, age, sex, and health status, were hypothesized on theoretical and empirical grounds to predict mortality. Face-to-face structured interviews were conducted with the same respondents in 1966, 1974, and 1986/87. Logistic regression establishes that a model comprising age, sex, participation in formal organizations, relative and children association, and general health status is a powerful predictor of mortality. The authors conclude that the more heterogeneous formal, or secondary, social networks which may enhance self esteem are most functional for the elderly.     

Themes from older men's lay definitions of successful aging as indicators of primary and secondary control beliefs over time: The Manitoba Follow-up Study

Constructs of control have theoretically been equated to successful aging in the psychology literature. Hence, we used themes from lay definitions of successful aging to quantify the prevalence of primary and secondary control beliefs over time. In doing so we hoped to shed new light upon the virtually uncharted area of older men's primary and secondary control beliefs over time. Using successful aging narratives spanning a 10-year timeframe from the Manitoba Follow-up Study cohort, we mapped themes from older men's lay definitions of successful aging onto Rothbaum, Weisz, and Snyder's (1982) constructs of primary and secondary control. We then examined the prevalence of the constructs of control over 10 years and found that some men emphasized primary control, some emphasized secondary control, and others emphasized both, prospectively. Counter to what had previously been theorized, many older men continued to emphasize primary control as important well into late life. As expected, secondary control became more important with age. Furthermore, among those men who endorsed both primary and secondary control, significantly more men switched emphasis from primary to secondary control beliefs as they aged. This finding supported Rothbaum et al.'s (1982) surmise that individuals could switch from one type of control to another, presumably as life circumstances dictated. Knowing which types of control beliefs older men emphasize as they age has theoretical and practical implications. Theoretically, it sheds new light on the under-researched area of control beliefs in older men. Practically, it is informative for anyone interested in enhancing older men's perceptions of control in very late life, particularly in the face of otherwise uncontrollable age-related decline and imminent demise.     

Grenzen der Meritokratie oder warum Quotenregulierungen sinnvoll sind

Economic theory has shown that economic discrimination can not persist for longer periods due to the intervention of market mechanisms. In contrast to this view, this article will demonstrate by using a theoretical model that in typical selection situations the practice of admitting persons to educational institutions while strongly discriminating against a particular group of applicants does not affect important success indicators of those educational institutions. As this observation also holds true under very general circumstances with respect to test reliabilities and distributional assumptions, it therefore can be used as a theoretical basis for many empirical investigations of persisting discrimination in non-economic spheres and for a general critique of meritocratic selection procedures.     

Volunteer Reliability in Nonprofit Organizations: A Theoretical Model

The reliability of volunteers is a major concern for many nonprofit organizations. To address this problem in more detail, we develop a theoretical model of volunteer reliability based on psychological contract theory. By taking this perspective as a starting point, we explore how individual volunteer characteristics, organizational factors, and sociological developments shape the exchange of inducements and contributions between volunteers and nonprofit organizations. We discuss how these factors can create tensions in the psychological contract and determine the extent to which volunteers behave reliably. As such, we develop a theoretical framework for addressing the reliability problem in volunteer management.
