EPG Model is an international business model including three dimensions – ethnocentric, polycentric and geocentric. It has been introduced by Howard V. Perlmutter within the journal article "The Tortuous Evolution of Multinational Enterprises" in 1969. [1]
Howard V. Perlmutter (4 November 1925 – 8 November 2011) [1] was an expert on Globalization and Internationalization of Companies. He specialized in the development of international enterprises.
The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
The ITRS defines a geocentric system of coordinates using the SI system of measurement. An International Terrestrial Reference Frame (ITRF) is a realization of the ITRS. Its origin is at the center of mass of the whole earth including the oceans and atmosphere.
Staffing is the process of finding the right worker with appropriate qualifications or experience and recruiting them to fill a job position or role. [ 1 ] [ 2 ] Through this process, organizations acquire, deploy, and retain a workforce of sufficient quantity and quality to create positive impacts on the organization's effectiveness. [ 3 ]
Staffing is typically greatest during the early phases of a mission, [3]: 21 and during critical procedures and periods, such as when a spacecraft is in eclipse and unable to generate power. [16] Increasingly commonly, control centers for uncrewed spacecraft may be set up for "lights-out" (or automated ) operation, as a means of controlling ...
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
