population transfer

(noun)

The movement of a large group of people from one region to another by state policy or international authority, most frequently on the basis of ethnicity or religion.

Examples of population transfer in the following topics:

  • Population Transfer

    • Population transfer is the movement of a large group of people from one region to another by state policy or international authority.
    • Population exchange is the transfer of two populations in opposite directions at about the same time.
    • The view of international law on population transfer underwent considerable evolution during the 20th century.
    • There is now little debate about the general legal status of involuntary population transfers, as forced population transfers are now considered violations of international law.
    • The Occupying Power shall not deport or transfer parts of its own civilian population into the territory it occupies.

  • Gene Transfer in Archaea

    • This phenomenon is described as horizontal gene transfer.
    • Horizontal gene transfer (HGT) refers to the transfer of genes between organisms in a manner other than traditional reproduction.
    • Some researchers suggest that individuals can be grouped into species-like populations given highly similar genomes and infrequent gene transfer to/from cells with less-related genomes, as in the Archaea genus Ferroplasma.
    • On the other hand, studies in Halorubrum found significant genetic transfer to/from less-related populations.
    • Taken together it is clear that gene transfer happens in Archaea, and probably is similar to horizontal gene transfer seen in the other domains of life.

  • Introduction to Plasmids

    • Plasmids can be considered part of the mobilome because they are often associated with conjugation, a mechanism of horizontal gene transfer.
    • Unlike viruses, they are naked DNA and do not encode genes necessary to encase the genetic material for transfer to a new host, though some classes of plasmids encode the sex pilus necessary for their own transfer.
    • Plasmid host-to-host transfer requires direct mechanical transfer by conjugation, or changes in incipient host gene expression allowing the intentional uptake of the genetic element by transformation.
    • Rather, plasmids provide a mechanism for horizontal gene transfer within a population of microbes and typically provide a selective advantage under a given environmental state.

  • Transition Metals

    • The Aufbau principle provides an methodical framework for predicting the order in which most atoms will populate their electron shells.
    • Color in transition-series metal compounds is generally due to the electronic transitions of two principal types of charge transfer transitions.
    • An electron may jump from a predominantly ligand orbital to a predominantly metal orbital, giving rise to a ligand-to-metal charge transfer (LMCT) transition.
    • This illustrates the order in which most atoms populate their electron shells.
    • I2•PPh3 charge-transfer complexes in CH2Cl2.

  • Vectors for Genomic Cloning and Sequencing

    • In molecular biology, a vector is a DNA molecule used as a vehicle to transfer foreign genetic material into another cell.
    • In molecular biology, a vector is a DNA molecule used as a vehicle to transfer foreign genetic material into another cell.
    • The purpose of a vector which transfers genetic information to another cell is typically to isolate, multiply, or express the insert in the target cell.
    • Conjugative vectors mediate DNA transfer through conjugation and therefore spread rapidly among the bacterial cells of a population, such as the F plasmid, as well as many R and some col plasmids.

  • Genomic Similiarities between Distant Species

    • Genetic distance refers to the genetic divergence between species or between populations within a species.
    • Genetic distance is useful in reconstructing the history of populations.
    • By examining the difference between allele frequencies between the populations, genetic distance can estimate how long ago the two populations were together.
    • Horizontal gene transfer (HGT), also known as lateral gene transfer, is the transfer of genes between unrelated species.
    • These gene transfers between species are the major mechanism whereby bacteria acquire resistance to antibiotics.

  • Logistic Population Growth

    • The successful ones will survive to pass on their own characteristics and traits (which we know now are transferred by genes) to the next generation at a greater rate: a process known as natural selection.
    • This population size, which represents the maximum population size that a particular environment can support, is called the carrying capacity, or K.
    • Thus, population growth is greatly slowed in large populations by the carrying capacity K.
    • This model also allows for negative population growth or a population decline.
    • This fluctuation in population size continues to occur as the population oscillates around its carrying capacity.

  • Disease in the New World

    • Rampant epidemic disease, to which the natives had no prior exposure or resistance, was one of the main causes of the massive population decline of the indigenous populations of the Americas.
    • Disease killed off a sizable portion of the populations before European observations and written records were made.
    • The transfer of disease between the Old World and New World was part of the phenomenon known as the Columbian Exchange.
    • The most vulnerable groups were those with a relatively small population and little built-up immunity.
    • While disease swept swiftly through the densely populated empires of Mesoamerica, the more scattered populations of North America saw a slower spread.

  • Estimates and Sample Size

    • Here, we present how to calculate the minimum sample size needed to estimate a population mean ($\mu$) and population proportion ($p$).
    • To calculate $E$, we need to know the desired confidence level (${ Z }_{ \frac { \alpha }{ 2 } }$) and the population standard deviation, $\sigma$.
    • When $n \geq 30$, the sample standard deviation ($s$) can be used to approximate the population standard deviation $\sigma$.
    • $p' = \frac{x}{n}$ is the point estimate for the population proportion
    • The Mesa College mathematics department has noticed that a number of students place in a non-transfer level course and only need a 6 week refresher rather than an entire semester long course.

  • Employee Transfers

    • Transfers take place in response to goals, needs, talent, or employee requests; HR evaluates and executes transfers.
    • Evaluating and executing employee transfers is an essential function of human resources management.
    • Transfers can occur for many different reasons; they can be driven by employees or managers.
    • Types of employee transfers include: strategic transfers, necessity transfers, and talent/management transfers.
    • A necessity transfer usually includes an incentive, like a raise, to give employees an incentive to put in the training the transfer will require.
