Core (anatomy)

In common parlance, the core of the body is broadly considered to be the torso. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck.

Muscles

Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm. Minor core muscles include the latissimus dorsi, gluteus maximus, and trapezius.

Functions of the core

The core is used to stabilize the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, feces, carbon-laden air, etc.).

Continence is the ability to withhold bowel movements, and urinary stress incontinence (the lack of bladder control due to pelvic floor dysfunction) can result from weak core musculature.

Disc jockey

A disc jockey (abbreviated DJ, D.J. or deejay) is a person who plays recorded music for an audience, either a radio audience if the mix is broadcast or the audience in a venue such as a bar or nightclub. In venues such as a club event or rave, this is an audience of dancers. Originally, "disc" (uncommonly spelled "disque" in French or commonly "disk" in American English) referred to phonograph records, not the later compact discs. Today, the term includes all forms of music playback, no matter which medium is used (e.g. vinyl, CDs, MP3 players).

The title "DJ" is also commonly used by DJs in front of their real names or adopted pseudonyms as a title to denote their profession and the music they play.

Types

There are several types of disc jockey. Radio DJs or radio personalities introduce and play music that is broadcast on AM, FM, digital or internet radio stations. Club DJs select and play music in bars, nightclubs or discothèques, or at parties or raves, or even in stadiums. Mobile DJs travel with portable sound systems and play recorded music at a variety of events. Some mobile DJs also serve as the master of ceremonies (MC) directing the attention of attendees, and maintaining a room-wide focus on what is included in the event's agenda. There are also many competitions that specialise in mixing, scratching or other kinds of techniques.

David Jones Limited

David Jones Limited, trading as David Jones (colloquially DJs), is an Australian department store, owned by South African retail group Woolworths Holdings Limited. David Jones was founded in 1838 by David Jones, a Welsh immigrant, and is the oldest continuously operating department store in the world still trading under its original name. It currently has 39 stores located in most Australian states and territories. David Jones' main department store rival is larger Myer. In mid 2016 David Jones will open their first New Zealand store in Wellington after buying Kirkcaldie & Stains.

History

David Jones, a Welsh merchant, met a Hobart businessman Charles Appleton in London. Appleton had established a store in Sydney in 1825 and Jones subsequently established a partnership with Appleton, moved to Australia in 1835, and the Sydney store became known as Appleton & Jones. When the partnership was dissolved in 1838, Jones moved his business to premises on the corner of George Street and Barrack Lane, Sydney. Jones survived the depression of the 1840s, and by 1856 had retired from active management of the business. A few years later when the firm failed, he returned to manage its affairs and in a few years had fully discharged all obligations to his creditors.
