Flattening is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution respectively. Other terms used oblateness; the usual notation for flattening is f and its definition in terms of the semi-axes of the resulting ellipse or ellipsoid is f l a t t e n i n g = f = a − b a. The compression factor is b/a in each case. For the ellipse, this factor is the aspect ratio of the ellipse. There are two other variants of flattening and when it is necessary to avoid confusion the above flattening is called the first flattening; the following definitions may be found in standard texts and online web texts In the following, a is the larger dimension, whereas b is the smaller. All flattenings are zero for a circle; the flattenings are related to other parameters of the ellipse. For example: b = a = a, e 2 = 2 f − f 2 = 4 n 2. Where e is the eccentricity. For the WGS84 ellipsoid to model Earth, the defining values are a: 6 378 137.0 m 1/f: 298.257 223 563from which one derives b: 6 356 752.3142 m,so that the difference of the major and minor semi-axes is 21.385 km.

Other values in the Solar System are Jupiter, f = 1/16. The flattening of the Sun is about 9×10−6. In 1687, Isaac Newton published the Principia in which he included a proof that a rotating self-gravitating fluid body in equilibrium takes the form of an oblate ellipsoid of revolution; the amount of flattening depends on the density and the balance of gravitational force and centrifugal force.

Proculus (prefect of Constantinople)

Proculus or Proklos was Eparch of Constantinople during the reign of Theodosius the Great (r. 379-395. An epigram on the pedestal of an obelisk at the hippodrome of Constantinople records his success in setting the obelisk upright. A Latin translation of the epigram by Hugo Grotius is given by Fabricius. Proculus was the son of Eutolmius Tatianus, he held the posts of Phoenicia. During this time, his name was carved on the Commemorative stela of Nahr el-Kalb. In 388, shortly before leaving for a campaign in the West against the usurper Magnus Maximus, Emperor Theodosius I appointed him praefectus urbi of Constantinople. In 392 he fell into disgrace: the general and statesman Rufinus, jealous of the power of Proculus and of his father, used his influence to launch accusations against Proculus, who went into hiding. Rufinus coaxed Tatianus and Theodosius to pardon Proculus, who received a letter from his father asking him to return to court. Once Proculus turned up, he was imprisoned, he was tried and sentenced, as Rufinus had decided, sent to death in a suburb of Constantinople called Sykai.

His name was subject to damnatio memoriae and was erased from monuments, as, for example, the Obelisk of Theodosius in the Hippodrome of Constantinople. His nephew, who came to power under the Emperor Marcian, had the good name of Proculus restored, re-carving it on the obelisk. Zosimus, Historia nea, iv.45.1, iv.52.1—4.

List of college football coaches with a .750 winning percentage

This is a list of football coaches with a.750 or greater winning percentage. College football coaches who have coached college teams for 10 or more seasons are included in the list. "College level" is defined as a four-year college or university program in either the National Association of Intercollegiate Athletics or the National Collegiate Athletic Association. If the team competed at a time before the official organization of either of the two groups, but is accepted as a "college football program," it is included. Leading the list is Larry Kehres, who compiled a.929 winning percentage while coaching the Mount Union Purple Raiders from 1986 to 2012. The longest tenure among coaches on the list is that of John Gagliardi, a head coach from 1949 until retiring after the 2012 season. Gagliardi leads all listed coaches in total games and losses. Former Vanderbilt head coach Dan McGugin has the most ties of anyone on the list. List may be incomplete. Note: As of the end of the 2010 season, Jim Tressel, who served as the head football coach for Youngstown State and Ohio State, had a career record of 241–79–2 for a winning percentage of.752.

In July 2011, Ohio State vacated all 12 of its wins from the 2010 season, dropping Tressel's career record to 229–79–2 and his winning percentage to.742. This list identifies active coaches who have: a winning percentage of.735 or greater after at least 10 full seasons as a college football head coach, or a winning percentage of.750 or greater after at least 7 full seasons, but fewer than 10, as a college football head coach.

Companionship Exemption

The companionship exemption refers to federal labor regulations in the United States that exclude workers providing companionship services to the elderly or disabled from the federal minimum wage and overtime protections that apply to most other American workers. The exemption came into existence in 1974 through an amendment to the Fair Labor Standards Act. While the main purpose of the amendment was to expand labor protections to domestic workers, two exceptions were included: one for those serving as “casual” babysitters and another for those providing “companionship services for individuals who are unable to care for themselves.” The United States Department of Labor holds significant discretion over how the companionship exemption is interpreted and applied in the workplace. Under the DOL’s current interpretation, the companionship exemption applies to most home care workers, allowing their employers—unless they are in a state with regulations superseding those at the federal level—to pay below minimum wage and avoid overtime compensation.

Since the companionship exemption was put in place, a variety of unsuccessful efforts have been made through legislation, court challenges, by the DOL itself to narrow the exemption so that more home care workers become eligible for minimum wage and overtime. In 2007, the case Long Island Care at Home, Ltd. v. Coke brought the issue of the companionship exemption in front of the United States Supreme Court. In this case, home care worker Evelyn Coke claimed she was unfairly denied minimum wage and overtime pay by her employer. While the court ruled against Coke, its decision reaffirmed the DOL’s authority to change its interpretation of the exemption at any time; the New York Times has written three editorials calling for an end to the companionship exemption. The disability community and many home care workers are concerned that the proposed changes will force seniors and people with disabilities into institutions, cut the take-home pay of attendants, reduce the available attendant workforce, force people with disabilities to cut the hours of longtime attendants and bring strangers into their homes, devastate consumer directed services.

They point out that the administration failed to adequately engage the disability community as described in Executive Order 13563. The sent a letter urging the Obama administration to use a negotiated rule-making to address this oversight; the Obama administration announced in December 2011 that it has proposed a regulation amending the companionship exemption. If implemented, the regulation would grant minimum wage and overtime protections to home care workers throughout the U. S; the regulation will become a final rule following a 60-day comment period. ADAPT still considers the issue unresolved. Source: On September 17, 2013, the U. S. Department of Labor announced a final rule extending the Fair Labor Standards Act’s minimum wage and overtime protections to most of the nation’s workers who provide essential home care assistance to elderly people and people with illnesses, injuries or disabilities; the Obama Administration anticipated that this change would provide FLSA protections to nearly two million direct care workers—such as home health aides, personal care aides and certified nursing assistant and help guarantee that those who rely on the assistance of direct care workers have access to consistent and high-quality care from a stable and professional workforce.

With an unprecedented 15 month implementation timeframe, the narrowing on the companionship exemption under FLSA, becomes effective January 1, 2015. The final rule, released October 2013, is intended to provide additional protections under FLSA for homecare workers and has been accompanied by dedicated webpages on the DOL's Wage an Hour website at
