 Problem E - Parity   (Site not responding. Last check: 2007-10-04) The parity of 1 is 1 (mod 2). The parity of 10 is 1 (mod 2). The parity of 1010 is 2 (mod 2). acm.uva.es /p/v109/10931.html   (151 words)

 Parity Parity is an important idea in quantum mechanics because the wavefunctions which represent particles can behave in different ways upon transformation of the coordinate system which describes them. In a famous experiment by C. Wu, the non-conservation of parity in beta decay was demonstrated. The electromagnetic and strong interactions are invariant under the parity transformation. hyperphysics.phy-astr.gsu.edu /hbase/quantum/parity.html   (433 words)

 parity - HighBeam Encyclopedia   (Site not responding. Last check: 2007-10-04) parity or space parity, in physics, quantity that refers to the relationship between an object or process and the image that it can produce in a mirror. Parity is still conserved in the strong nuclear interactions and in the electromagnetic interactions. Formally, parity, P, is a quantity that expresses the behavior of the wave function of any system of particles when the spatial coordinates x, y, z, of the wave function are reflected through the origin to - x, - y, - z (see quantum theory). www.encyclopedia.com /doc/1E1-parity.html   (456 words)

 Parity Plus, A powerful technical analysis tool Parity's charting capabilities permit you to graph a security's price, volume and up to nine indicators in a single chart using any combination of stacked or overlapping panes, each of which can include one or more indicators. Parity includes nine different methods for calculating the composite ranging from simple sums and averages to complex geometric and harmonic means. Parity's ability to create a chart showing stock price, position status, cumulative profits, and profits per position at the click of the button for each security you test is another powerful feature. usecinternational.com /ParityPlus/index.htm   (1849 words)

 Parity   (Site not responding. Last check: 2007-10-04) Parity is a property important in the quantum-mechanical description of a physical system. For either parity the physical observables, which depend on the square of the wave function, are unchanged. This law of the conservation of parity was explicitly formulated in the early 1930s by the Hungarian-born physicist Eugene P. Wigner and became an intrinsic part of quantum mechanics. abyss.uoregon.edu /~js/glossary/parity.html   (424 words)

 Theory: Parity Invariance (SLAC VVC) A parity transformation about that origin would relocate the object at a point found by flipping that position vector so it goes the same distance from the origin but in exactly the opposite direction. Parity invariance is true for strong and electromagnetic interactions. One of the big surprises of the 1950s was the recognition that parity invariance is not true for weak interactions. www2.slac.stanford.edu /vvc/theory/parity.html   (417 words)

 Parity The second is that lack of parity has terrible consequences in the lives of people with mental illnesses and their families. Parity presumes the management of treatment to assure that it is medically necessary and to assure that care is delivered on an outpatient rather than an inpatient basis whenever possible. This is important to be clear about because one of the strangest sources of opposition to parity laws is the argument that it should be rejected because it does not solve all of the problems of mental health insurance coverage. mhawestchester.org /advocates/parity403.asp   (3060 words)

 Mental Health Parity rpeort- Executive Summary An overview of parity legislation on the national level (Appendix A) and an example of estimating the costs of mental health parity in Florida for individuals with severe mental disorders (Appendix B) are also provided. In addition, since the parity laws differ from state to state, one state's parity structure and resulting cost/utilization outcome is not necessarily applicable to another state. Thus, the definition of the specific type of parity legislation as well as the population to be covered are critical elements in parity legislative development. www.fmhi.usf.edu /parity/parityreport/execsum.html   (2157 words)

 Evaluation of Parity in the Federal Employees Health Benefits (FEHB) Program: Final Report Executive Summary In interpreting the results of the actuarial analysis of parity alongside the statistical analysis of the policy change it is important to bear in mind key differences in methodology and definitions used in the two sets of analyses. The Parity evaluation compared the before/after change in trend for the FEHB population to expenditure patterns for a matched control group of large insured populations to control for what the trend would have been absent parity. The impact of the parity policy was assessed in detail in nine FEHB plans that reflect both fee-for-service and health maintenance organizations from regions across the country where Federal employees, their dependents, and retirees reside. aspe.hhs.gov /daltcp/reports/parityes.htm   (3527 words)

 Costs and Effects of Parity - Case Studies, National Mental Health Information Center Therefore, we chose the four states that required parity in coverage for private-sector employees on or before 1995 (Maryland, Minnesota, New Hampshire, and Rhode Island), and Texas, which is one of two states with a law applying to coverage for public employees. Parity resulted in only a small increase in MH/SA benefits in New Hampshire and Rhode Island, in part because the 1995 laws apply to a small number of people (those with SMI), and New Hampshire had generous benefits before parity was implemented. State MH/SA parity laws do not affect most people in employer-sponsored health plans because they are enrolled in a self-funded plan (exempt under ERISA), or because they are in a small employer plan (exempt from the state law). mentalhealth.samhsa.gov /publications/allpubs/Mc99-80/prtych2.asp   (2954 words)

 Behavioral Healthcare Parity Parity means treating behavioral health illnesses (both mental health and substance abuse) in the same manner as other physical conditions in the construction of health care benefits. In opposition to parity, health insurance representatives point out that the premium increase varies depending on the degree to which the care is managed, with PPO and fee-for-service plans projecting an average 5 percent increase. The state of Vermont successfully negotiated and enacted behavioral health parity legislation that is considered the most comprehensive, to date, and includes coverage for both mental health and substance abuse. www.naswdc.org /practice/behavioral_health/behavioral.asp   (2142 words)

 parity The puzzle is hard until you study the parity of each layer, then the problem becomes simple. Since any rectangle with an area of 210 has a balanced parity when you color the squares, the tiling is impossible. A grid with a parity of six, such as the side-six trapezoid, is impossible. www.mathpuzzle.com /parity.html   (602 words)

 History of Science: Parity Violation The importance of parity conservation, its fundamental nature, was discovered in 1927 by the physicist Eugene Wigner, Wigner proved that Laporte's rule was a consequence of right-left symmetry (or mirror image symmetry) of the electromagnetic force[1]. Conservation of parity rested upon Maxwell's equations describing electromagnetism, but more important, the intuitive idea that nature should be left-right symmetric had been established on the quantum level. In their paper, Lee and Yang stated, "To decide unequivocally whether parity is conserved in weak interactions, one must perform an experiment to determine whether weak interactions differentiate the right from the left."

 Parity - Wikipedia, the free encyclopedia Parity is a concept of equality of status or functional equivalence. in economic history, parity was the ratio of farm income to farm expenditure with 1910-1914 as a base. In Human Genetics, base parity is the G/C ratio in regions of DNA. en.wikipedia.org /wiki/Parity   (363 words)

 Parity and Profits Basically, parity is a measuring device that puts the value of raw commodities at a level that equals all the costs, including labor costs and capital costs. Parity, George Warren said, was based on a market basket of what was happening in the rest of the economy, which whipped around and provided the requirement for the first part of the economy, which was agriculture. Later their publications said that parity was a theory and a form that no longer mattered. www.westonaprice.org /farming/parity.html   (3210 words)

 Race 2 Win - Parity? Maybe I have blinders on and I'm missing the picture, but there is no more parity in Winston Cup than there are a shortage of fights on the Jerry Springer show. Just to be sure that my definition of parity was correct, or if the definition might have changed, I looked it up in Webster's dictionary. Brinster will be saying that there is parity among the Busch regulars and the Cup guys driving in the Busch series. www.angelfire.com /sc/race2win/holtz3.html   (437 words)

 Overturning of Parity Law in Nuclear Physics Basically, parity conservation in quantum mechanics means that two physical systems, one of which is a mirror image of the other, must behave in identical fashion. If parity is conserved in such interactions, then the intensity of the beta emission should be the same in either direction along the axis of spin. This result unequivocally demonstrated that parity is not conserved in the emission of beta particles by cobalt-60. physics.nist.gov /GenInt/Parity/expt.html   (1760 words)

 What is parity checking? - A Word Definition From the Webopedia Computer Dictionary The parity bit for each unit is set so that all bytes have either an odd number or an even number of set bits. Parity checking is the most basic form of error detection in communications. Parity checking is used not only in communications but also to test memory storage devices. www.webopedia.com /TERM/P/parity_checking.html   (367 words)

 Character Parity   (Site not responding. Last check: 2007-10-04) Parity is an error detection technique which is typically used on asynchronous links. Parity may also be calculated in software using a shift register to count the number of '1' bits in each byte. When the calculated parity from the received character does not match the value of the received parity bit, then a parity error is said to have occurred, and the character is normally discarded. www.erg.abdn.ac.uk /users/gorry/eg2069/parity.html   (415 words)

 Auto-selectable self-parity generator (US5355377) A 9th data input from another parity generator on the system mother board is compared to the generator tree output when DRAM is written to. If a mismatch occurs, the type of parity generated by the generator tree is opposite to the type of parity that the mother board generates, and the parity tree output must be inverted on subsequent reads. The state of the latch is used to output the correct type of parity on a read from DRAM by inverting the output of the parity generating circuit if needed. www.delphion.com /details?pn=US05355377__   (599 words)

 Parity Loopholes Should Be Closed Case studies of five states that had a parity law for at least a year revealed a small effect on premiums – at most a change of a few percent, plus or minus. In addition to requiring dollar limit parity, these more comprehensive laws may also require parity in service limits and cost-sharing provisions and mandate the inclusion of mental health benefits in group health plans. Premium cost increases for full parity are estimated to be between 2% and 4%, both nationally and for individual states. www.apa.org /practice/parity2001_8.html   (1041 words)

 Cisco - Cisco 7200 Parity Error Fault Tree Parity checking is capable of detecting a single bit error by using a simple method; adding one check bit per eight bits of data. Parity errors may cause the system to reset and can be a transient Single Event Upset (SEU or soft error) or can occur multiple times (often referred to as hard errors) due to damaged hardware. An imprecise parity error is when the CPU reads information without blocking, and later determines there was a parity error in the associated cache line. www.cisco.com /warp/public/63/c7200_faulttree.html   (1861 words)

 What is parity? - a definition from Whatis.com Parity bit checking is not an infallible error-checking method since it's possible that two bits could be in error in a transmission, offsetting each other. Parity checking is also used in communication between modems. When no parity is selected (or defaulted), it's assumed that there are other forms of checking that will detect any errors in transmission. searchstorage.techtarget.com /sDefinition/0,,sid5_gci212748,00.html   (472 words)

 The National Association of Hispanic Journalists   (Site not responding. Last check: 2007-10-04) The Parity Project is part of a five-year strategic plan that NAHJ adopted in October of 2002 in Washington, D.C. That same year, NAHJ called on the news industry to increase dramatically the employment of Latino journalists during the next five years. The Parity Project involves NAHJ’s work with selected English-language news organizations that serve large Latino communities, but that do not have a representative percentage of Latino journalists in their newsrooms. Through the Parity Project, NAHJ helps these organizations to accomplish two main goals: 1) to find and hire more journalists who happen to be Latino for their newsroom job openings. www.nahj.org /parityproject/parityproject.shtml   (504 words)

 State Laws Mandating or Regulating Mental Health Benefits   (Site not responding. Last check: 2007-10-04) Parity, as it relates to mental health and substance abuse, prohibits insurers or health care service plans from discriminating between coverage offered for mental illness, serious mental illness, substance abuse, and other physical disorders and diseases. Others feel that anything other than full parity is discrimination against the mentally ill. Some of these laws specify that copayments and deductibles must be equal to those for physical illness up to the required level of benefits provided. The law, otherwise known as the Mental Health Parity Act of 1996 (Public Law 104-204, see text online), prohibits group health plans that offer mental health benefits from imposing more restrictive annual or lifetime limits on spending for mental illness than are imposed on coverage of physical illnesses. www.ncsl.org /programs/health/mentalben.htm   (2564 words)

 Frequently Asked Questions About The Mental Health Parity Act MHPA provides for parity in the application of aggregate lifetime and annual dollar limits on mental health benefits with dollar limits on medical/surgical benefits. Plans are still able to set the terms and conditions (such as cost-sharing and limits on the number of visits or days of coverage) for the amount, duration and scope of mental health benefits. Once a plan qualifies for the 1 percent increased cost exemption, it does not have to comply with the parity requirements for the life of the MHPA provisions. www.dol.gov /ebsa/faqs/faq_consumer_mentalhealthparity.html   (523 words)

 Parity (physics) - Wikipedia, the free encyclopedia In a two-dimensional plane, parity is the same as a rotation by 180 degrees. In general one assigns the parity of the most common massive particles, the proton, the neutron and the electron, to be +1. This implies that parity is not a symmetry of our universe, unless a hidden mirror sector exists in which parity is violated in the opposite way. en.wikipedia.org /wiki/Parity_(physics)   (2046 words)
