Adulthood
An adult is a human or other animal that has reached full growth. In human context, the term ''adult'' has meanings associated with social and legal concepts. In contrast to a " minor", a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and responsible. They may also be regarded as a "major". The typical age of attaining legal adulthood is 18, although definition may vary by legal rights, country, and psychological development. Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; a person may be biologically an adult, and have adult behavior, but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may define an adult character. In different cultures there are events that relate passing from being a child to becomin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Age Of Majority
The age of majority is the threshold of legal adulthood as recognized or declared in law. It is the moment when minors cease to be considered such and assume legal control over their persons, actions, and decisions, thus terminating the control and legal responsibilities of their parents or guardian over them. Most countries set the age of majority at 18, but some jurisdictions have a higher age and others lower. The word ''majority'' here refers to having greater years and being of full age as opposed to ''minority'', the state of being a minor. The law in a given jurisdiction may not actually use the term "age of majority". The term typically refers to a collection of laws bestowing the status of adulthood. Those under the age of majority are referred to as minors and may be legally denied certain privileges or rights (e.g. the right to vote, buy alcohol, marry, sign a binding contract). Age of majority should not be confused with the age of maturity, age of sexual consent, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maturity Model
Maturity is a measurement of the ability of an organization for continuous improvement in a particular discipline (as defined in O-ISM3 ). The higher the maturity, the higher will be the chances that incidents or errors will lead to improvements either in the quality or in the use of the resources of the discipline as implemented by the organization. Most maturity models assess qualitatively people/culture, processes/structures, and objects/technology. Two approaches for implementing maturity models exist. With a top-down approach, such as proposed by Becker et al., a fixed number of maturity stages or levels is specified first and further corroborated with characteristics (typically in form of specific assessment items) that support the initial assumptions about how maturity evolves. When using a bottom-up approach, such as suggested by Lahrmann et al., distinct characteristics or assessment items are determined first and clustered in a second step into maturity levels to induce a ...

Capability Maturity Model
The Capability Maturity Model (CMM) is a development model created in 1986 after a study of data collected from organizations that contracted with the U.S. Department of Defense, who funded the research. The term "maturity" relates to the degree of formality and optimization of processes, from ''ad hoc'' practices, to formally defined steps, to managed result metrics, to active optimization of the processes. The model's aim is to improve existing software development processes, but it can also be applied to other processes. In 2006, the Software Engineering Institute at Carnegie Mellon University developed the Capability Maturity Model Integration, which has largely superseded the CMM and addresses some of its drawbacks. Overview The Capability Maturity Model was originally developed as a tool for objectively assessing the ability of government contractors' ''processes'' to implement a contracted software project. The model is based on the process maturity framework first des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developmental Age
Human fertilization is the union of a human ovum, egg and spermatozoon, sperm, occurring primarily in the Fallopian tube#Ampulla, ampulla of the fallopian tube. The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the nineteenth century. The process of fertilization involves a sperm fusing with an ovum. The most common sequence begins with ejaculation during sexual intercourse, copulation, follows with ovulation, and finishes with fertilization. Various exceptions to this sequence are possible, including artificial insemination, In vitro fertilization, ''in vitro'' fertilization, external ejaculation without copulation, or copulation shortly after ovulation. Upon encountering the secondary oocyte, the acrosome of the sperm produces enzymes which allow it to burrow through the outer shell called the zona pellucida of the egg. The sperm plasma then fuses w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mature Technology
A mature technology is a technology that has been in use for long enough that most of its initial faults and inherent problems have been removed or reduced by further development. In some contexts, it may also refer to technology that has not seen widespread use, but whose scientific background is well understood. Its performance characteristics are also expected to be well understood with well-established design specifications. One of the key indicators of a mature technology is the ease of use for both non- experts and professionals. Another indicator is a reduction in the rate of new breakthrough advances related to it—whereas inventions related to a (popular) immature technology are usually rapid and diverse, and may change the whole use paradigm—advances to a mature technology are usually incremental improvements only. Examples The QWERTY keyboard design is an example of mature technology because its performance characteristics such as typing speeds and error rates ...

Maturity (finance)
In finance, maturity or maturity date is the date on which the final payment is due on a loan or other financial instrument, such as a bond or term deposit, at which point the principal (and all remaining interest) is due to be paid. Most instruments have a ''fixed maturity date'' which is a specific date on which the instrument matures. Such instruments include fixed interest and variable rate loans or debt instruments, however called, and other forms of security such as redeemable preference shares, provided their terms of issue specify a maturity date. It is similar in meaning to "redemption date". Some instruments have ''no fixed maturity date'' which continue indefinitely (unless repayment is agreed between the borrower and the lenders at some point) and may be known as "perpetual stocks". Some instruments have a range of possible maturity dates, and such stocks can usually be repaid at any time within that range, as chosen by the borrower. A ''serial maturity'' is when b ...

Maturity (geology)
In petroleum geology, the maturity of a rock is a measure of its state in terms of hydrocarbon generation. Maturity is established using a combination of geochemical and basin modelling techniques. Rocks with high total organic carbon, (termed source rocks), will alter under increasing temperature such that the organic molecules slowly mature into hydrocarbons (see diagenesis). Source rocks are therefore broadly categorised as ''immature'' (no hydrocarbon generation), ''sub-mature'' (limited hydrocarbon generation), ''mature'' (extensive hydrocarbon generation) and ''overmature'' (most hydrocarbons have been generated). The maturity of a source rock can also be used as an indicator of its hydrocarbon ''potential''. That is, if a rock is sub-mature, then it has a much higher potential to generate further hydrocarbons than one that is overmature.

Maturity (psychological)
In psychology, maturity can be operationally defined as the level of psychological functioning (measured through standards like the Wechsler Intelligence Scale for Children) one can attain, after which the level of psychological functioning no longer increases much with age. However, beyond this, integration is also an aspect of maturation, such as the integration of personality, where the behavioral patterns, motives and other traits of a person are gradually brought together, to work together effectively with little to no conflict between them, as an organized whole, e.g., bringing a person's various motives together into a purpose in life. Case in point: adult development and maturity theories include the purpose in life concept, in which maturity emphasizes a clear comprehension of life's purpose, directedness, and intentionality, which contributes to the feeling that life is meaningful. The status of maturity is distinguished by the shift away from reliance on guardianship and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maturity (sedimentology)
In sedimentary geology, maturity describes the composition and texture of grains in clastic rocks, most typically sandstones, resulting from different amounts of sediment transportation. A sediment is mature when the grains in a sediment become well-sorted and well-rounded due to weathering or abrasion of the grains during transport. There are two components to describe maturity, ''texture'' and ''composition''. Texture describes how rounded and sorted the sample is while composition describes how much the composition trends toward stable minerals and components (often quartz). A mature sediment is more uniform in appearance, for the sediment grains are well rounded, are of a similar size and exhibit little compositional variation. Conversely, an immature sediment contains more angular grains, diverse grain sizes, and is compositionally diverse. As the sediment is transported, the unstable minerals are abraded or dissolved to leave more stable minerals, such as quartz. Matur ...

Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood, but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.) Role of reproductive organs Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompani ...

Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules.
