Context paragraphs:
King Schools, Inc.: King Schools, Inc. is an American computer software company headquartered in San Diego, California, USA.  The company focuses on the creation of Computer Based Training (CBT) or E-learning, to assist individuals in obtaining all levels of Pilot certification in the United States.  Over the years, the company has expanded its training courses to cover the various pilot certificates, ratings and educational requirements, along with many aeronautical elective studies.  More recently, it has begun offering all of its courses in Web-based training (WBT) and mobile device formats.

Centre for Child Protection: The Centre for Child Protection (CCP) was launched in Munich in January 2012 by the Institute of Psychology of the Pontifical Gregorian University in Rome in cooperation with the Archdiocese of Munich and Freising and the Department of Child and Adolescent Psychiatry and Psychotherapy of the State University Clinic of Ulm.  The founding of the CCP was part of a global initiative for the prevention of sexual abuse of minors.  After successful completion of the pilot phase at the end of 2014, the CCP relocated its headquarters to Rome in January 2015.  The CCP is part of the academic structure of the Pontifical Gregorian University as part of the Institute of Psychology.  It closely collaborates with the Faculties of Theology, Canon Law, and Social Sciences.  A main task of the institution is the creation of a global e-learning training centre for pastoral professions responding to the sexual abuse of minors, taking into account multilingual and intercultural issues.

Skillsoft: Skillsoft is an American educational technology company that produces learning management system software and content.  s of 2014 , it was one of the world's largest corporate training providers, with 10,000 customers, 60 million users, and 2,400 employees.

WebCT: WebCT (Course Tools) or Blackboard Learning System, now owned by Blackboard, is an online proprietary virtual learning environment system that is licensed to colleges and other institutions and used in many campuses for e-learning.  To their WebCT courses, instructors can add such tools as discussion boards, mail systems, and live chat, along with content including documents and web pages.  The latest versions of this software are now called Webcourses.  WebCT is significant in that it was the world's first widely successful course management system for higher education.  At its height, it was in use by over 10 million students in 80 countries.

Distributed element filter: A distributed element filter is an electronic filter in which capacitance, inductance and resistance (the elements of the circuit) are not localised in discrete capacitors, inductors and resistors as they are in conventional filters.  Its purpose is to allow a range of signal frequencies to pass, but to block others.  Conventional filters are constructed from inductors and capacitors, and the circuits so built are described by the lumped element model, which considers each element to be "lumped together" at one place.  That model is conceptually simple, but it becomes increasingly unreliable as the frequency of the signal increases, or equivalently as the wavelength decreases.  The distributed element model applies at all frequencies, and is used in transmission line theory; many distributed element components are made of short lengths of transmission line.  In the distributed view of circuits, the elements are distributed along the length of conductors and are inextricably mixed together.  The filter design is usually concerned only with inductance and capacitance, but because of this mixing of elements they cannot be treated as separate "lumped" capacitors and inductors.  There is no precise frequency above which distributed element filters must be used but they are especially associated with the microwave band (wavelength less than one metre).

K–Ar dating: Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology.  It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).  Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites.  In these materials, the decay product Ar is able to escape the liquid (molten) rock, but starts to accumulate when the rock solidifies (recrystallizes).  The amount of Argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material, and a number of other factors.  These factors introduce error limits on the upper and lower bounds of dating, so that final determination of age is reliant on the environmental factors during formation, melting, and exposure to decreased pressure and/or open-air.  Time since recrystallization is calculated by measuring the ratio of the amount of Ar accumulated to the amount of K remaining.  The long half-life of K allows the method to be used to calculate the absolute age of samples older than a few thousand years.

ChinaCast Education: ChinaCast Education Corporation (Public, NASDAQ:CAST), People's Republic of China.  Established in 1999, ChinaCast Education Corporation is a leading for-profit, post-secondary education and e-learning services provider in the People's Republic of China.
