life span

Examples of life span in the following topics:

• Plant Life Spans

  • The life cycles and life spans of plants vary and are affected by environmental and genetic factors.
  • The length of time from the beginning of development to the death of a plant is called its life span.
  • Biennials, such as carrots, complete their life cycle in two seasons.
  • Perennials, such as the magnolia, complete their life cycle in two years or more.
  • Other polycarpic species, such as perennials, flower several times during their life span, but not each year.

• Practice 2: Hypothesis Testing for Two Averages

  • Center for Disease Control reports that the mean life expectancy for whites born in 1900 was 47.6 years and for nonwhites it was 33.0 years.
  • Of the 124 whites, the mean life span was 45.3 years with a standard deviation of 12.7 years.
  • Of the 82 nonwhites, the mean life span was 34.1 years with a standard deviation of 15.6 years.
  • Conduct a hypothesis test to see if the mean life spans in the county were the same for whites and nonwhites.

• Age and Race

  • There is evidence that black senior citizens are more likely to be abused - both physically and psychologically and suffer greater financial exploitation than do white senior citizens.Further, recent demographic profiles suggest that social aging varies across racial groups, and demonstrates that minority elders (especially Hispanic and African American identified) typically enter later life with less education, less financial resources, and less access to health care than their white counterparts.Finally, researchers have noted that minority groups' greater likelihood of facing patterns of structural disadvantage throughout the life course, such as racial discrimination, poverty, and fewer social, political, and economic resources on average, create significant racial variations in the stages or age-related trajectories of racial minorities and majorities that may be observed at all points of the life span, and contribute to disparities in health, income, self-perceived age, mortality, and morbidity.
  • As a result, sociologists often explore the timing (in both subjective and objective conceptualizations of age) of varied life events within and between racial groups while exploring ways that age-related disparities influence the structural realities and bio-social outcomes of people located within different racial groups.

• Socialization Throughout the Life Span

  • Any study that focuses on how cultural context influences individual development is an example of the life course approach.
  • Socialization is a process that continues throughout an individual's life.
  • The life course approach was developed in the 1960s for analyzing people's lives within structural, social and cultural contexts.
  • Origins of this approach can be traced to such pioneering studies as Thomas's and Znaniecki's "The Polish Peasant in Europe and America" from the 1920s or Mannheim's essay on the "Problem of generations. " The life course approach examines an individual's life history and how early events influence future decisions.
  • The life course approach studies the impact that sociocultural contexts have on an individual's development, from infancy until old age.

• Stages of Socialization Throughout the Life Span

  • Socialization is a life process, but is generally divided into two parts: primary and secondary socialization.
  • Primary socialization takes place early in life, as a child and adolescent.
  • Secondary socialization refers to the socialization that takes place throughout one's life, both as a child and as one encounters new groups that require additional socialization.
  • The need for later-life socialization may stem from the increasing complexity of society with its corresponding increase in varied roles and responsibilities.
  • Give examples of how the socialization process progresses throughout a person's life

• Dividing the lifespan

  • Human life is often divided into various age spans, like the following:
  • These divisions are somewhat arbitrary, but generally capture periods of life that reflect a certain degree of similarity.

• The Middle Years

  • Various attempts have been made to define this age, which is around the third quarter of the average life span.
  • In general, life expectancy in developing countries is much lower and the risk of death at all ages is higher.
  • Middle-aged people benefit from greater life experience than they had when they were young; this contributes to happiness and makes emotional responses to stress less volatile.
  • Diana DeGette, a politician from Colorado, was born in 1957 and is in the middle age stage of life.

• Age

  • Successful aging consists of three components: 1) Low probability of disease or disability; 2) high cognitive and physical function capacity; and 3) active engagement with life.
  • Successful aging may be viewed an interdisciplinary concept, spanning both psychology and sociology, where it is seen as the transaction between society and individuals across the life span with specific focus on the later years of life.
  • Discuss the impact of aging on a person's life and the demand it places on health care

• Half-Life of Knowledge

  • As a result, the span of time between learning something new, being able to apply it, and finding that it is outdated and no longer useful continues to decrease.
  • This phenomenon is what Gonzalez refers to as the "half-life" of knowledge - the time span from when knowledge is gained until it becomes obsolete (2004).
  • Since the advent of technology, from the radio to the internet, the half-life of knowledge has decreased significantly.

• The Life Course

  • The life course approach analyzes people's lives within structural, social, and cultural contexts.
  • The life course approach, also known as the life course perspective, or life course theory, refers to an approach developed in the 1960s for analyzing people's lives within structural, social, and cultural contexts.
  • In a more general reading, human life is seen as often divided into various age spans such as infancy, toddler, childhood, adolescence, young adult, prime adulthood, middle age, and old age .
  • This man is well into his later years and depicts life in its final stages.
  • This picture depicts an individual at the earliest of life stages.
