<P0-S0> Core stability refers to a person's ability to stabilize their core. <P0-S1>  Stability, in this context, should be considered as an ability to control the position and movement of the core. <P0-S2>  Thus, if a person has greater core stability, they have a greater level of control over the position and movement of this area of their body. <P0-S3>  The body's core is frequently involved in aiding other movements of the body, such as the limbs, and it is considered that by improving core stability a person's ability to perform these other movements may also be improved i.e. core stability training may help improve someone's running ability. <P0-S4>  The bodies core region is sometimes referred to as the torso or the trunk, although there are some differences in the muscles identified as constituting them. <P0-S5>  The major muscles involved in core stability include the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm. <P0-S6>  The minor muscles involved include the latissimus dorsi, gluteus maximus, and trapezius. <P0-S7>  Notably, breathing, including the action of the diaphragm, can significantly influence the posture and movement of the core; this is especially apparent in regard to extreme ranges of inhalation and exhalation. <P0-S8>  On this basis, how a person is breathing may influence their ability to control their core. <SEP> <P1-S0>  He left the party and became a radio reporter, eventually becoming president of the Philadelphia Association of Black Journalists. <P1-S1> Mumia Abu-Jamal (born Wesley Cook; April 24, 1954) is a convicted murderer, American activist and journalist who became involved in black nationalism in his youth and was a member of the Black Panther Party until October 1970. <P1-S2>  He was convicted and sentenced to death in 1982 for the murder of Philadelphia police officer Daniel Faulkner. <P1-S3>  After numerous appeals, his sentence was commuted in 2001 to life imprisonment without parole. <SEP> <P2-S0> Mumia most commonly refers to Mumia Abu-Jamal (born 1954), a convicted murderer. <SEP> <P3-S0> The need for affiliation (N-Affil) is a term that was popularized by David McClelland and describes a person's need to feel a sense of involvement and "belonging" within a social group; McClellend's thinking was strongly influenced by the pioneering work of Henry Murray who first identified underlying psychological human needs and motivational processes (1938). <P3-S1>  It was Murray who set out a taxonomy of needs, including achievement, power and affiliation—and placed these in the context of an integrated motivational model. <P3-S2>  People with a high need for affiliation require warm interpersonal relationships and approval from those with whom they have regular contact. <P3-S3>  Having a strong bond with others make a person feel as if they are a part of something important that creates a powerful impact. <P3-S4>  People who place high emphasis on affiliation tend to be supportive team members, but may be less effective in leadership positions. <P3-S5>  A person who takes part in a group, whether it be a movement or project, create a push towards a sense of achievement and satisfaction for the individual and the whole.
