Combined total measure of a person's work experience and of social position in relation to others
Based on income education and occupation
43
Diversity in the systems level
Individual-each of us is unique (intragroup heterogeneity)
Relationship -each of us shares traits with others (inter group diversity)
Society - each of us is like everyone else (humanity)
44
Convergence theory
A theory of aging that states that old age is a leveler reducing inequality that was evident at earlier sages in life course
45
Multiple hierarchy stratification
Race class gender and age are all sources of inequality
46
Theory of cumulative disadvantage
Those that begin life with more resources continue to have more resources to have opportunities to accumulate even more while those with fewer resources fall behind
47
Where can resilience come from
Personal (spirituality confidence), cultural beliefs (tradition values) social (friends family)
48
Mortality crossover effect
If you survived through multiple forms of adversity in your life that you extend your life expectancy
49
Role theory
Shifting of roles as we move through age norms - assumptions or age related capacities
Age normative expectations - ages that things should be done or not done
Socialization-the way society conveys age norms
Role discontinuity skills learned in one field become contradictory to another role
50
Activity theory
Well adjusted individuals take on productive roles throughout the life course replacing old roles
51
Disengagement theory
Older adults withdraw from society and transfer power to younger generations
52
Gerotranscendence theory
Older individuals become more spirituals rather than materialists
53
Age stratification theory
Life course and soiciohistorical experiences cause differences in thinking between cohorts that can lead to conflict
54
Social exchange theory
Older adults contribute wisdom and experience in lieu of economic production in society
55
Political economy of aging
Social class plays a big detentions at of the aging process and that problems on the societal level are the reason for inequity among older groups
56
Feminist theory
Gender should be a primary consideration when attempting to understand the aging process.
57
Wear and tear hypothesis
Organisms wear out from metabolizing cell reproduction etc
| Cells that become damages can't be repaired especially in tissue cells that do not undergo cell division
58
Antagonistic plietropty
What is good for reproductive fitness may not be good in older age
Eg: anti cancer genes that become cellularly senescent are good in early stages of life for warding off cancer but limit ability for cell division and life span late in the future
59
Free radicals
Highly reactive molecules that damage important cellular structures including DNA
Genotoxicity can lead to cancer causing mutations or decrease in cell function
60
Cross linking
Free radicals bonding with proteins which reduces collagen flexibility and makes AGEs
61
Support ratio
Indoviduals able to economically support retired indoviduals of society
Issues with this theory are that
-dependents to working ratio but something's wrong with this ratio is that the age limits of being dependent are not always accurate
62
Pensioners democracy
Where the old "plunder(take too much) from the young
63
What states typically have the oldest Americans
Florida, West Virginia,
64
Senescent fibroblast
Secrete collagenase which destroy the collagen they used to produce which creates a favorable environment for tumor growth
Collagen is used to maintain the strictest of the tissue and plays an important role in wound healing
65
Lipofuscin
Oxidized fatty substance that causes liver spots
66
Heterogeneity
Even in a cohort of people born in similar times there exists significant differences
67
Health disparities
Racial and class inequalities in health mortality and life course conditions
68
Ethnogerontology
Study of causes processes and consequences of race national origin on individual and societal aging
69
Modernization theory
Modernization of society has caused older people to lose social and political power causing increased comp between older and younger gens
70
Scientific Tech
More jobs for young but more displacement of elders
71
Early vs late stages of modernization
Early stages- occupational and educational status of older adults declines
Later stages-differences between gens decrease and older person status rises J shape
72
Person-environment congruence model
Behavior is influenced and adjusted by interactions in the environment around us based on our abilities in varying areas
73
Freud theories
Psychosexual stage is development and as adolescence as a reflection of unconscious motives of childhood
74
Jungs Psychoanalytic Perspective
- move from extra version in youth to intraversion in adulthood
- as you get older people start to express the traits of the opposite sex
- anima:feminine side of mans personality
- animus:masculine side of female personality
75
Eriksons psychological model
8 stages with the unconscious goal of who identity
3 stages in adolescence
Epigenetic principle- people proceed through the stages as they become for cog and emotionally capable with association with a greater social radius
Last stage=ego integrity vs despair -either content with life and accepting of death or not accepting of death because of lack of satisfaction in life
-achieving ego integrity allows the individual to feel generativity or the desire to share wisdom with youth
76
Loveingers perspective
Most people don't move past stage 2 of conscientious conformist and the the last stage is integrated which is similar to eriksons last stage
77
Levinsons seasons of life
Very concrete and logical
| Pre adulthood, early adulthood,middle adulthood,late adulthood
78
The shift in social aging theories
Shift from objective quantitative methods to subjective interpretation of aging based or individuals interactions with structural factors
79
Symbolic interaction ism
Interactions between individuals and their environment affect people's experience of the aging process themselves
80
Political economy of aging
Structural factors enforced by public policy limit oops and choices later in life
81
Critical theory
Focuses on changes that can be made to improve adverse conditions caused by structural inequities
82
Disposable soma theory
Because the individuals genes have been passed on, the body can be disposed of and age
83
Accidental cell death
Cell dies due to lack of nutrients and broken down through the process of necrosis and can release contents that trigger inflammatory responses that damage tissue
84
Apoptosis
Genetically programmed cell suicide where the nuclear breaks down and is normal and essential to various organ systems
Also protects from cancer
85
Cellular senescence hypothesis
When somatic cells can't undergo replication they are under replicators senescence
When the telomeres become too short and the cell is affected by radiation chemicals or oxidative stress p53 protein is activated to do with temp suspension of cell division, apopstosis, or senescence
86
Wear and tear hypotheis
Accumulation of Lipofuscin which is dead red blood cells that leave pigment yellow
AGEs-cross linked proteins advanced glycation end products
----Can cause more cross linking and free radicals
87
Oxidative stress free radical hypotheis
Aging is a consequence of accumulated cellular damage caused by internal free radicals
Stemmed from the rate of living hypothesis which is no longer accepted put said that the lifespan of an organism is related to metabolic rates
-- suggested that animals with slower metabolism live longer
88
Free radicals
Contributors to forming of crosslinked proteins that make cell membrane more rigid which makes it harder to transport nutrients and waster across the permeable cell membrane
Usually counteracted by antioxidants
89
Arthritis
Second most chronic condition after cancer
Contains varying degenerative conditions of inflammation
Rheumatoid - inflammation of membranes lining joints and tendons
Osteoarthritis - degeneration of joints most commonly subjected to stress hands knees hips shoulders
90

93
Three classes of elders
1. No longer economically productive but still mentally capable to attend to daily needs
2. Those who are functionally dependent and can be seen as a burden
3. Those who are still active participants in the economy and social environment through self employment farming or
94
Highest rates of independent living in?
Immigrants of Cuba Japan and white
95
4 criterion for biological basis of aging
1. apply to everyone(UNIVERSAL)

108
Voting?
Voting differences are greater within than between age groups
109
Proponents of argument for older adults holding power
AARP Cast as a rep of older adults
1. Access to legislators
2. Seems legit so able to gain public platforms
3. Mass membership so can organize larger campaigns
110
Politics of entitlement
Failure model of old age- elders seen as dependent and needy
Other groups pay for the benefits of elders
111
Politics of productivity
Expanding economy in which older adults can contribute
| Older people can help younger people in interdependent society
112
Inter generational inequity framework
Measure the relative hardships of one generation in comparison to another gernerstion
Ex: having to pay for SS benefits for elders causes younger women to not be able to support their children
113
Interdependence of generations framework
Sharing of burdens and solidarity across generations
114
