Young Adult
A young adult is generally a person in the years following adolescence. Definitions and opinions on what qualifies as a young adult vary, with works such as Erik Erikson's stages of human development significantly influencing the definition of the term; generally, the term is often used to refer to adults in approximately the age range of 18 to 35 or 39 years. However, the term ''young adult'' is very often misused informally or in literary sense to refer to children down to ages 12 or 13 due to the category of young adult literature targeting this demographic in the lower age limit. This broad extension of ''young adult'' to minors has been greatly disputed, as they are not considered adults by the law or in any other cultures outside of religion (such as the Bar or Bat Mitzvah in Judaism), and the tradition of ''biological'' adulthood beginning at puberty has become archaic. The young adult stage in human development precedes middle adulthood.Martin BrinerErik Erikson page, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erik Erikson
Erik Homburger Erikson (born Erik Salomonsen; 15 June 1902 – 12 May 1994) was a German-American developmental psychologist and psychoanalyst known for his theory on psychological development of human beings. He coined the phrase identity crisis. Despite lacking a university degree, Erikson served as a professor at prominent institutions, including Harvard, University of California, Berkeley, and Yale. A ''Review of General Psychology'' survey, published in 2002, ranked Erikson as the 12th most eminent psychologist of the 20th century. Early life Erikson's mother, Karla Abrahamsen, came from a prominent Jewish family in Copenhagen, Denmark. She was married to Jewish stockbroker Valdemar Isidor Salomonsen, but had been estranged from him for several months at the time Erik was conceived. Little is known about Erik's biological father except that he was a non-Jewish Dane. On discovering her pregnancy, Karla fled to Frankfurt am Main in Germany where Erik was born on 15 June 19 ...

Fertility
Fertility is the capability to produce offspring through reproduction following the onset of sexual maturity. The fertility rate is the average number of children born by a female during her lifetime and is quantified demographically. Fertility is addressed when there is a difficulty or an inability to reproduce naturally, which is referred to as infertility. Infertility is widespread, with fertility specialists available all over the world to assist mothers and couples who experience difficulties having a baby. Human fertility depends on factors of nutrition, sexual behaviour, consanguinity, culture, instinct, endocrinology, timing, economics, personality, way of life, and emotions. Fertility differs from fecundity, which is defined as the ''potential'' for reproduction (influenced by gamete production, fertilization and carrying a pregnancy to term). Where a woman or the lack of fertility is infertility while a lack of fecundity would be called sterility. Demography I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Expectancy
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. ''Cohort'' LEB is the mean length of life of a birth cohort (all individuals born in a given year) and can be computed only for cohorts born so long ago that all their members have died. ''Period'' LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year. National LEB figures reported by national agencies and international organizations for human populations are estimates of ''period'' LEB. In the Bronze Age and the Iron Age, human LEB was 26 years; in 2010, world LEB was 67.2 years. In recent years, LEB in Eswatini (formerly Swaziland) is 49, while LEB in Japan is 83. The combination of high infant mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
