Research on meditation

Since the 1950s hundreds of studies on meditation have been conducted, though many of the early studies were flawed and thus yielded unreliable results. More recent reviews have pointed out many of these flaws with the hope of guiding current research into a more fruitful path.

Research on the processes and effects of meditation is a growing subfield of neurological research. Modern scientific techniques and instruments, such as fMRI and EEG, have been used to see what happens in the bodies of people when they meditate, and how their bodies and brains change after meditating regularly.

Meditation is a broad term which encompasses a number of practices.

Christian meditation

Christian meditation is a form of prayer in which a structured attempt is made to become aware of and reflect upon the revelations of God. The word meditation comes from the Latin word meditārī, which has a range of meanings including to reflect on, to study and to practice. Christian meditation is the process of deliberately focusing on specific thoughts (such as a bible passage) and reflecting on their meaning in the context of the love of God.

Christian meditation aims to heighten the personal relationship based on the love of God that marks Christian communion. Both in Eastern and Western Christianity meditation is the middle level in a broad three-stage characterization of prayer: it involves more reflection than first level vocal prayer, but is more structured than the multiple layers of contemplative prayer. Teachings in both the Eastern and Western Christian churches have emphasized the use of Christian meditation as an element in increasing one's knowledge of Christ.

Méditation (Thaïs)

"Méditation" (pronounced: [meditasjɔ̃]) is a symphonic intermezzo from the opera Thaïs by French composer Jules Massenet. The piece is written for solo violin and orchestra. The opera premiered at the Opéra Garnier in Paris on March 16, 1894.

Description

The Méditation is a symphonic entr'acte performed between the scenes of Act II in the opera Thaïs. In the first scene of Act II, Athanaël, a Cenobite monk, confronts Thaïs, a beautiful and hedonistic courtesan and devotée of Venus, and attempts to persuade her to leave her life of luxury and pleasure and find salvation through God. It is during a time of reflection following the encounter that the Méditation is played by the orchestra. In the second scene of Act II, following the Méditation, Thaïs tells Athanaël that she will follow him to the desert.

The piece is in D major and is approximately five minutes long (although there are a number of interpretations that stretch the piece to over six minutes). Massenet may also have written the piece with religious intentions; the tempo marking is Andante religioso, signifying his intention that it should be played religiously (which could mean either strictly in the tempo or literally with religiously-founded emotion) and at walking tempo. The piece opens with a short introduction by the harps, with the solo violin quickly entering with the motif. After the violin plays the melody twice, the piece goes into a section marked animato, gradually becoming more and more passionate (Massenet wrote poco a poco appassionato). The climax is reached at a place marked poco piu appassionato (a little more passion) and is then followed by a short cadenza-like passage from the soloist and returns to the main theme. After the theme is played twice, the soloist joins the orchestra while playing harmonics on the upper register as the harps and strings quietly play below the solo line.

List of Internet top-level domains

This list of Internet top-level domain extensions contains all top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet.

The official list of all top-level domains is maintained by the Internet Assigned Numbers Authority (IANA). IANA also oversees the approval process for new proposed top-level domains. As of January 2016, the root domain contains 1205 top-level domains, while a few have been retired and are no longer functional.

Types

As of 2015, IANA distinguishes the following groups of top-level domains:

Original top-level domains

Seven generic top-level domains were created early in the development of the Internet, and pre-date the creation of ICANN in 1998.

Organic unit

An organic unit is a military unit that is a permanent part of a larger unit and (usually) provides some specialized capability to that parent unit. For instance, the US Marine Corps incorporates its own aviation units (distinct from the US Air Force and US Navy) that provide it with fire support, electronic warfare, and transport.

At a lower level of organization, infantry units commonly incorporate organic armour or artillery units to improve their combined arms capability. Organic assets are closely integrated into their parent unit's command structure and their personnel are familiar with other personnel in the parent unit, improving coordination and responsiveness and making the parent unit more self-sufficient.

However, over-emphasis of organic assets can create wasteful redundancy. For instance, an infantry unit assigned to urban peacekeeping duties might have little use for its organic artillery, while another unit deployed elsewhere might have less artillery support than it required. The question of how much to emphasise the use of organic assets, as opposed to coordination with separate units ('joint organization') is a subject of debate and heavily dependent on questions of command and control.
