African American History and Women Timeline 1700-1799

African American History and Women Timeline 1700-1799 [Previous] [Next] Women and African American History: 1700-1799 1702 New York passed a law prohibiting public gatherings by three or more enslaved Africans, prohibiting testimony in court by enslaved Africans against white colonists, and prohibiting trade with enslaved Africans. 1705 Virginia Slave Codes of 1705 were enacted by the House of Burgesses in the Colony of Virginia.   These laws more clearly delineated differences in rights for indentured servants (from Europe) and slaves of color.   The latter included enslaved Africans and Native Americans sold to colonists by other Native Americans.   The codes specifically legalized the trade in enslaved people and established rights of ownership as property rights.   The codes also prohibited the Africans, even if free, from striking white people or owning any weapons.   Many historians agree that this was a response to events, including Bacons Rebellion, where white and black servants had united. 1711 A Pennsylvania law outlawing slavery was overturned by Britains Queen Anne.New York City opened a public slave market on Wall Street. 1712 New York responded to a slave revolt that year by passing legislation targeting black and Native Americans.   The legislation authorized punishment by slave owners and authorized the death penalty for enslaved Africans convicted of murder, rape, arson or assault.   Freeing those enslaved was made more difficult by requiring a significant payment to the government and an annuity to the one freed.   1721 The colony of South Carolina limited the right of voting to free white Christian men. 1725 Pennsylvania passed  An Act for the Better Regulating of Negroes in this Province, providing more property rights to owners, limiting contact and freedom of Free Negroes and Mulattoes, and requiring a payment to the government if a slave were freed. 1735 South Carolina laws required freed slaves to leave the colony within three months or return to enslavement. 1738 Fugitive slaves establish a permanent settlement at Gracia Real de Santa Teresa de Mose, Florida. 1739 A few white citizens in Georgia petition the governor to end bringing Africans to the colony, calling enslavement a moral wrong. 1741 After trials for conspiracy to burn down New York City, 13 African American men were burned at the stake, 17 African American men were hanged, and two white men and two white women were hanged.  South Carolina passed more restrictive slave laws, permitting the killing of rebellious slaves by their owners, banning the teaching of reading and writing to enslaved people and prohibiting enslaved people from earning money or gathering in groups. 1746 Lucy Terry wrote Bars Fight, the first known poem by an African American. It was not published until after Phillis Wheatleys poems were, passed down orally until 1855.   The poem was about an Indian raid on Terrys Massachusetts town. 1753 or 1754 Phillis Wheatley born (enslaved African, poet, first published African American writer). 1762 Virginias new voting law specifies that only white men may vote. 1773 Phillis Wheatleys book of poems, Poems on Various Subjects, Religious and Moral, was  published in Boston and then in England, making her the first published African American writer, and the second book by a woman to be published in the land which was about to become the United States. 1777 Vermont, establishing itself as a free republic, outlawed slavery in its constitution, allowing indentured servitude bound by their own consent.   Its this provision that grounds the claim of Vermont to be the first state in the United States to outlaw slavery. 1780 - 1781 Massachusetts, the first New England colony to legally establish slave ownership, found in a series of court cases that slavery was effectively abolished   African American men (but not women) had the right to vote. Freedom came, in fact, more slowly, including some enslaved Africans becoming indentured. By 1790, the federal census showed no slaves in Massachusetts. 1784 (December 5) Phillis Wheatley died (poet, enslaved African; first published African American writer) 1787 Thomas Jeffersons daughter, Mary, joins him in Paris, with Sally Hemings, likely his wifes enslaved half-sister,   accompanying Mary to Paris 1791 Vermont was admitted to the Union as a state, preserving a slavery ban in its constitution. 1792 Sarah Moore Grimke born (abolitionist, womens rights proponent) 1793 (January 3) Lucretia Mott born (Quaker abolitionist and womens rights advocate) 1795 (October 5, 1795)  Sally Hemings  gives birth to daughter, Harriet, who dies in 1797.

C5 - Managerial Economics - Essay Example The objective of the paper is to provide advice to a large travel agency of Hong Kong from an economic point of view in order to reassess the company’s business strategies. Relevant official data available in the government sites, the local airlines, and travel agencies will also be collected to facilitate the analysis in this study. Our prime focus will be to provide an in-depth analysis of the pricing strategies adopted by the local airline industry by using the concepts of market structure, cost and revenue structure and price discrimination. With this purpose, an in-depth analysis will be conducted through literature review describing the current business environment of Hong Kong airline industry. 2 Background 2.1 Theoretical Background Evidences have revealed that economic factors have a significant influence on the business environment of any and every region (The Times 100, 2008; Kitching & Et. Al., 2009; Floyd & Wooldridge, 1997). Based on this concept, experts have fi rmly stated that macro and micro economic factors, both play a crucial role in influencing the pricing strategies of an industry. Besides, the macroeconomic environment which may greatly affect the demand side of the market, the micro economic factors can be witnessed in terms of the market structure of the industry, the price discrimination taking place in the market scenario, its cost and revenue structure as well as the demand elasticity observed in the industry (Nadar & Vijayan, 2009). Musonera & Ndagijimana (2001) stated that the pricing strategies of an organisation depend largely on the political, economical, technological and social factors. For instance, when the economic factors tend to be highly fluctuating, the pricing strategies of organisations are developed to be flexible which can effectively deal with the economic variations. It is in this context that the aforementioned factors create a string impact on the market structure of firms in an industry which in turn inf luences its pricing structure (Mazzucato, 2000). Hong Kong airline industry is scrutiny by various regulatory bodies, such as Civil Aviation Department, International Air Transport Association (IATA), Airport Authority Hong Kong and others. These regulatory bodies deliver the industry with a strong and well-organised structure (Information Services Department, 2010). The initial factor that will be considered in this study is the influence of market structure on the pricing strategies of the airline industry. Market structure relates to various elements existing in the business environment such as product differentiation, market concentration, economies of scale, vertical integration of the competitors in the market and other similar aspects that in turn define the market structure of an industry. Therefore, market structure can be defined as â€Å"the organisational characteristics of a market that largely determine where it fails on competitive spectrum between monopoly and compe tition†

Sound Waves Lab Report Example | Topics and Well Written Essays - 250 words

Sound Waves - Lab Report Example Fourier Transform essentially incorporates a time series of pressure intensity in the determination of the perfect pitched frequencies summation. It also incorporates the level of the amplitude to recreate the original sound. Series of data aids in telling the amplitude of the sound as a function of time to a corresponding series data that determines the amplitude of the frequencies for recreation of the sound. Based on the graphs collected the ambiguity within the time durations and frequencies measured for diverse sound waves emanated from the errors in the measurement Logger Pro. The percentage error amidst the tuning fork frequency and corresponding measured frequencies was less that 1%, which is relatively safe. The percentage error amidst the printed frequency and the measured frequency was 0.58% as depicted by the sine curve. Undertaking the curve fit is relatively more precise measurement method regarding finding the frequency since it is not subjective to many of individual’s errors. The concept of Fourier Transforms is fundamental in the examination of the sound waves. Moreover, it integrates a time series of pressure intensity in the resolving the perfect pitched frequencies summation. Series of data display amplitude of the sound as a function of time to a corresponding series data that determines the amplitude of the frequencies for recreation of the sound. There was certain error in the lab experiment that mainly occurs due to the individual’s point of view of the underlying maximum intensity, within is not fundamental to other

Reimbursement and Pay-for-Performance Essay Example for Free

Reimbursement and Pay-for-Performance Essay Introduction As we come into the 21st Century, we find Healthcare is at a crisis level. Every agency is working on healthcare reform from policymakers to the public and private sector, as well as federally funded Medicare and Medicaid. The business of Medicine is greatly influenced by the government (federal, state and local levels) and private health sections that initiate policies. Pay for Performance is a reimbursement method where physicians and hospitals can receive a higher reimbursement for duplicate services based on the fact that they deliver better quality care with better results and outcomes. This payment reform offers initiates intended to improve efficiency, value, and quality of health care (Hood, 2007). If all doctors receive the same dollar amount as a doctor with poor outcomes, then the doctor with great outcomes should receive a little more and there will be patients that do not mind paying a higher deductible for better medical services (Mayes, 2006). Definition for Pay for performance Kimmel (2005), Pay for performance is a payment approach used in healthcare that is based on clinical information-driven reform. The fundamental concept is to tie payment to how well providers adhere to practice standards. The practice standards are evidence-based and tied to clinical outcomes. The primary areas of focus are preventive care delivery and disease management for chronic illnesses†. Effects on Reimbursement Pay for performance (P4P) is literally a group of performance indicators that are coupled with an incentive. The performance indicators supports the performance aspect of P4P while the incentive indicator is the pay component. Measuring patient outcomes and understanding the variances that  they have, has in part lead to the increasing rise in how pay for performance reimbursement is looked at. This style of reimbursement allows health plans and employers to pay increasing reimbursements to medical providers that have the better outcomes, give average outcome medical providers a chance to improve, and pay those medical providers with the lowest outcomes the least amount of money or not pay them at all (Cromwell, Trisolini, Pope, Mitchell, Greenwald. 2011). In order to have a pay for performance system in place, you must decide what domains or areas you wish to track, measure, and reward. Some areas in this domain are clinical process, quality and patient safety, access to and availability of care, cost efficiency or cost of care, cost-effectiveness, administrative efficiency and compliance, adoption of information technology, and reporting of performance indicators. These can be set up as a single performance tracker or a multi-domain performance tracker and the measure needed for improvement, importance, and cost. Performance indicators should be valid, reliable, and informative (Cromwell, Trisolini, Pope, Mitchell, Greenwald. 2011). The Incentive Schemes reward the performance measures, and is another important part of a pay for performance system. Funding proves to be another important part of this type of a reimbursement system. Types of funding include redistributing existing payments where additional funds will not have to be made and the quality of service is already high; however, medical providers with a lower quality of service will receive lower reimburse ments. Generated Savings and New Money are other sources of funding for performance measures. Generated savings claim that an increased quality of service will generate savings, although there are others who feel that new money should be used to fund the performance system. (Cromwell, Trisolini, Pope, Mitchell, Greenwald. 2011). Impact of System Cost Reductions on the Quality and Efficiency of Health Care The Medicare Physicians Group Practice (PGP) was the first physician pay for performance model used by the federal government. The PGP believes that higher quality and better cost efficiency could be achieved by managing and coordinating patient care and by engaging in wider choices of care management that are able to improve cost efficiency and quality of health care. Interventions include; chronic disease management, high risk and higher cost care management, transitional care management, end-of-life and palliative care programs. If there were a more  successful payment and delivery method to increase the value of health care and improve quality of care, the cost would grow at a slower pace. The American people would be more likely to purchase health insurance coverage that is affordable and more valuable. (Kautter, Pope, Trisolini, 2007). More progress toward effective delivery and system reform is one of the key elements to achieving the goals to push expanded coverage. Information technology is one of these key elements and a major part of pay for performance system. Information systems uses electronic medical records and patient registries have been created to improve the efficiency and quality of health care delivery. These type of initiatives that are being tested to see if cost savings are generated by reducing avoidable hospital stays, cutting down on readmissions and emergency room visits, while simultaneously improving quality of care (Kautter, Pope, Trisolini, 2007). Effect of Pay for performance on Health Care Providers and Their Customers Meredith B. Rosenthal states, Pay for performance will not replace the existing payment structure in either system, but it does allow payors to take into account a set of quality indicators, in addition to volume of service (as fee-for-service does now) or the number of covered lives (in the case of capitation). In this view, pay for performance can be viewed as a mechanism to correct some of the distortionary incentives that already exist in the reimbursement system. Physicians in the United States are paid on a fee-for-service basis. This encourages high volumes of services, where there is no regard to the value of services in regards to a patient. When services are reimbursed more generously than others it allows the payment system to influence additional medical services with a heavy emphasis on procedure-based care. Since the physicians pay is not attached to medical services provided, there is really no direct incentive to provide any services (How Will Paying for Performance Affect Patient Care?. (2006, March). Virtual Mentor, 8(3), 162-165). Effects of Pay for performance on the Future of Health Care Goldberg lists three points regarding the most significant implications of the movement toward paying for quality outcomes. These are that the quality and value become real parts of contractual reimbursement, the differences based on quality outcomes will be more evident grouped with provider tiers,  and quality metrics evolve to outcome-based and chronic disease management (Goldberg 2006). P4P is an incentive-based reimbursement system that rewards the best players. This pay for performance system is currently active in health systems, managed care settings, and private and group physician’s practices. P4P is likely to impact the entire health care environment and will provide yet another opportunity for pharmacy to become an active role player and leader with improving quality and efficient health care. The focus is not on value but on quality and cost. Pay for performance is not a new program, but in the age of informed choice, evidence based medicine, and patient safety, it can become the solution to our current health care dilemma (Pay for performance (P4P): Evaluating Current and Future Implications). Conclusion These pay for performance systems and programs will lead expansion across the United States health care industry in the near future. With the implementation of the Affordable Care Act, there has been a great amount of provision made to encourage continued improvement with quality of care. Accountable Care Organizations (ACOs) are groups of providers that agree to coordinate care and to be held accountable for the quality and cost of the services they provide (James, 2012). There needs to be a consensus as to how much of an incentive will have to be given in order to affect the needed change and how should these incentives be paid out monthly, quarterly, or yearly; and how can these improvements be sustained over time. Continued experimentation with the pay for performance model should begin to incorporate monitoring and evaluation in identifying design elements that will also affect outcomes in a positive way. Variations in health care markets should be evaluated and include comparison groups to isolate pay for performance from other types of factors. Pay for performance has some great attributes to it and could definitely be the beginning to improvements in quality of service. If physicians are receiving patients and referrals based on their ability to provide quality of service with reduced readmissions and more satisfied consumers, then the care they take in providing services to patients from admission to discharge will create positive change.

Physics Behind Why Rockets Fly :: physics rocket rockets fly

In order for any rocket to fly, it must obey some basic rules of physics. No rocket can escape the cardinal rule that the center of gravity must be in front of the center of pressure. Center of Gravity The Center of Gravity or Cg is the point that behaves as if all the mass was concentrated in that one spot. Simply put it is the point at which you could balance the rocket on your finger. The Cg is also the point around which the rocket rotates. This becomes very important for the rocket's stability as you will soon see. Center of Pressure The Center of Pressure or Cp is similar to the Cg. The Cp is the point at which the forces from the air pushing on the vechicle seem to be focused. What is a Cg or a Cp? Basic Rocket Why Does This Matter ? When a rocket is in flight, the force of the air pushing on it keeps the Cp behind the Cg. This is important because the rocket is pushed by the force of the exhaust coming out the back. If the Cp was in front of the Cg, the rocket would want to spin around (so that its back was pointing forwards).. However, because the exhaust is always pushing the rocket forward, it spins around again and again... and you get the picture from there. Fins So now that you know all about Cgs and Cps, it should make perfect sense what fins are for. Still a little confused? The fins are extra surface area near the back of the rocket. This brings the Cp further back on the rocket without significantly moving the Cg.. Calculating Cp Calculating a Cp is rather involved. The easiest way to do it is by using Barrowman's Equations, although these are still fairly complicated. I was going to explain them, but I found a site that does a better job than I could ever do. The UAF Student Rocket Project builds and flies sounding rockets with help from Wollops Flight Facilty. Our latest mission, SRP4, is a student designed and built payload. It will be carrying a science instrument designed by students and professors at Toyama Prefectual University in Japan. Our goal is to measure the D-region of the ionosphere. SRP4 will fly atop an Orion sounding rocket motor that will be supplied by NASA's Wollops Flight Facility. We expect to launch from Poker Flat Research Range in March of 2002.
