Unit 5 discussion board - Essay Example In 2002, 70% of the notebook PCs sold were offered with a rebate and the concept seems simple enough (McGinn, 2003). Buy a $1000 notebook and save $200 after filling in the required paperwork, sending it into a third party processing center, and waiting the required number of weeks for your check to arrive. This is a great deal for the manufacturer as they have sold you a PC that was on sale for $800 and then asked you to loan them $200 for a couple of months. No interest is offered, and there is a risk that you may never see your money. Manufacturers rely on human nature to misplace the paperwork, send it in incomplete, or forget it ever existed. For the people that do get the rebate, they merely break even. The sellers have increased cash flow and sold a number of their products at $200 above market value. These practices are as deceptive as a carnival shell game and could have a negative effect on a companys reputation Whether a consumer will even apply for the rebate is largely determined by the amount being offered. While cosmetics that offer $1 back may go discarded, more expensive items will naturally get a better response. However, even on high-dollar electronics the rates can be surprisingly low. Timothy Silk, a University of Florida researcher, found, "...redemption rates, even on larger-ticket purchases such as computers and televisions, are well below 50 percent" (Keen, 2004). Networking accessories manufacturer Asante Technologies sees an even lower response rate. Jim Hsia, vice president of marketing says, "the typical redemption rate for his companys products hovers between 2 and 15 percent" (Millard, 2003). Most people will never see a rebate. In new car sales, rebates can work against the automakers intentions. A consumer electronics rebate can be used to attract attention to an item and create store traffic. However, on an expensive purchase such as a new car, the customer sees the rebate as part

Literature Sources for Nurse Administrators

Literature Sources for Nurse Administrators Pramila Chaudhary Nurse leaders today are assuming active role in planning, designing, managing, and organizing patient care delivery models in order to meet the challenges of mounting health care costs faced by health care settings. Department of Health and Human Services, through their Medicare Shared Savings Program, released a rule in 2011, to reward Account Care Organizations that lower healthcare cost and meet evidence-based quality performance parameters (Hajewski, 2014). A nurse administrator in healthcare setting is required to implement measures to find efficient ways of providing nursing care, safety, quality outcomes, and staff development. Planning care management based on evidence and research are within scope of nursing and the conceptual framework of management and leadership (Galganski, 2006). Nurse administrators today have access to many sources of financial and business literature regarding current trends in health care changes and its implication to leadership and management theor y.

The article in American Journal of Nursing by Wallis (2014-11), â€Å"CMS to Compensate Providers for Coordinating Care† discusses how nurse practioners may be compensated for services they already provide to chronically ill patients they care for. According to Wallis (2014), CMS establishes new policy to pay for coordination of care in management of multiple chronic health conditions. This policy is geared towards better access and quality of care for Medicare beneficiaries. The article also discusses patient centered care document and Shared Savings Program for long-term care management services. Nurse leaders may apply methods based on information from credible journals to improve care in an efficient manner. The article, â€Å"Physician Practice Participation in Accountable Care Organizations: The Emergence of the Unicorn† by Shortell et al., (2014) analyses a study to evaluate participation of physicians and healthcare management processes to provide efficient care in Accountable care Organizations. Shortell et al., (2014) argue that the affordable care act expansion of coverage will not remain affordable over time, unless hospitals find a way to deliver care more efficiently and effectively. Lewis et al., in their article found in the Cochrane Library database, discussed increasing demand for healthcare providers to reduce costs in surgical cases. Lewis et al., propose that studies did not reveal a clear difference between care provided by anesthesiologist and nurse anesthetist when it came to adverse patient outcomes like death. As healthcare expands in the Affordable Heath Care Act, hospitals are driven toward using nurse anesthetists in order to implement cost reducing measures (Lewis et al., 2014). Nursing leadership can use this study to relate to their facility. Conclusion In conclusion, nurse leaders and managers have access to current and credible literature from wide range of disciplines ranging from nursing, medicine, social sciences, business, finance, and research regarding evidence based practice and quality measures, and management and leadership topics, which is useful in planning and directing nursing care as well as implement changes on policies and procedures that need to be re evaluated. Nursing management includes direct care managers who are responsible for primary care, middle managers who are responsible for coordinating care between departments, and nurse executives who are responsible for directing care in a healthcare facility; reviewing the literature is equally valuable for all levels of management for guiding decisions based on current knowledge. Nurse educators and faculty uses literature review as a teaching strategy, and for professional development of graduating nurses. Searching databases like CINAHL and PubMed will provide a wide range of nursing practice and related discipline topics, in addition nurse administrators need to consider rising health care costs and new regulations to form partnership with government such as Shared Medicare Savings program pose new challenges for todays nursing administrators.

What Is Power Electronics Engineering Essay

What Is Power Electronics Engineering Essay Power electronics involves the study of electronic circuits intended to control the flow of electrical energy. These circuits handle power flow at levels much higher than the individual device ratings. It has been said that people do not use electricity, but rather they use communication, light, mechanical work, entertainment, and all the tangible benefits of both energy and electronics. In this sense, electrical engineering is a discipline very much involved in energy conversion and information. In the general world of electronics engineering, the circuits engineers design and use are intended to convert information, with energy merely a secondary consideration in most cases. This is true of both analog and digital circuit design. In radio frequency applications, energy and information are sometimes on a more equal footing, but the main function of any circuit is that of information transfer. What about the conversion and control of electrical energy itself? Electrical energy sources are varied and of many types. It is natural, then, to consider how electronic circuits and systems can be applied to the challenges of energy conversion and management. This is the framework of power electronics, a discipline that is defined in terms of electrical energy conversion, applications, and electronic devices. More specifically, Rectifiers are probably the most familiar example of circuits that meet this definition. Inverters (a general term for dc-ac converters) and dc-dc converters for power supplies are also common applications. As shown in Fig. 1.1, power electronics represents a median point at which the topics of energy systems, electronics, and control converge and combine [1].Any useful circuit design for the control of power must address issues of both devices and control, as well as of the energy itself. Among the unique aspects of power electronics are its emphasis on lar ge semiconductor devices, the application of magnetic devices for energy storage, and special control methods that must be applied to nonlinear systems. In any study of electrical engineering, power electronics must be placed on a level with digital, analog, and radio-frequency electronics if we are to reflect its distinctive design methods and unique challenges. FIGURE 1.1 Control, energy, and power electronics are interrelated. All power electronic circuits manage the flow of electrical energy between some sort of source and a load. The parts in a circuit must direct electrical flows, not impede them. A general power conversion system is shown in Fig. 1.2. The function of the power converter positioned at the middle is that of controlling energy flow between a given electrical source and a given load. For our purposes, the power converter will be implemented with a power electronic circuit. As a power converter appears between a source and a load, any energy used within the converter is lost to the overall system. A crucial point emergesà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬to build a power converter, we should consider only lossless components. A realistic converter design must approach 100% efficiency. A power converter connected between a source and a load also affects system reliability. FIGURE 1.2 General systems for electric power conversion A circuit built from ideal switches will be lossless. As a result, switches are the main components of power converters, and many people equate power electronics with the study of switching power converters. Magnetic transformers and lossless storage elements such as capacitors and inductors are also valid candidates for use in power converters. The complete concept, shown in Fig. 1.3, illustrates a power electronic system. Such a system consists of an energy source, an electrical load, a power electronic circuit, and control functions. The power electronic circuit contains switches, lossless energy storage elements, and magnetic transformers. The controls take information from the source, load, and designer and then determine how the switches operate to achieve the desired conversion. The controls are usually built up with conventional low-power analog and digital electronics. FIGURE 1.3 a basic power electronic system Trends in Power Supplies : As costs of electronics decline, the power supply becomes a larger fraction of system cost and design effort. One major manufacturer estimates that power supply cost will soon reach 50% of the total cost of a typical electronic product such as a cordless telephone or personal computer. Thus, new technology developments in power supplies are critically important. In the past, bulky linear power supplies were designed with transformers and rectifiers from the ac line frequency to provide low-level dc voltages for electronic circuits. Late in the 1960s, use of dc sources in aerospace applications led to the development of power electronic dc-dc conversion circuits for power supplies. In a typical power electronics arrangement today, an ac source from a wall outlet is rectified without any transformation; the resulting high dc voltage is converted through a dc-dc circuit to the 5V, 12 V, or other level required. These switched-mode power supplies are rapidly supplanting linear supplies across the full spectrum of circuit applications. A personal computer commonly requires three different 5V supplies, two .12 V supplies, a ÃÆ' ¿12 V supply, a 24 V supply, and perhaps a few more. This does not include supplies for 1 Introduction 3 video display or peripheral devices. Only a switched-mode supply can support such complex requirements without high costs. The bulk and weight of linear supplies make them infeasible for hand-held communication devices, calculators, notebook computers, and similar equipment. Switched-mode supplies often take advantage of MOSFET semiconductor technology. Trends toward high reliability, low cost, and miniaturization have reached the point at which a 5 V power supply sold today might last 1,000,000 hr (more than 100 yr), provide 100Wof output in a package with volume This type of supply brings an interesting dilemma: the ac line cord to plug it in actually takes up more space than the power supply itself. Innovative concepts such as integrating a power supply within a connection cable will be used in the future. Device technology for power supplies is being driven by expanding needs in the automotive and telecommunications industries as well as in markets for portable equipment. The automotive industry is making a transition to 42 V systems to handle increasing electric power needs. Power conversion for this industry must be cost effective, yet rugged enough to survive the high vibration and wide temperature range to which a passenger car is exposed. Global communication is possible only when sophisticated equipment can be used almost anywhere. This brings a special challenge, because electrical supplies are neither reliable nor consistent throughout much of the world. While in North America voltage swings in the domestic ac supply are often Given the enormous size of worldwide markets for telephones and consumer electronics, there is a clear need for flexible-source equipment. Designers are challenged to obtain maximum performance from small batteries, and to create equipment with minimal energy requirements. DEVICE TYPE CHARACTERISTICS OF POWER DEVICES Diode: Current ratings from 5000 A. Voltage ratings from 10V to 10 kV or more. The fastest power devices switch in BJT (Bipolar Junction Transistor): Conducts collector current (in one direction) when sufficient base current is applied. Power device current ratings from 0.5 to 500 A or more; voltages from 30 to 1200V. Switching times from 0.5 to 100 ms. The function applies to dc-dc circuits; combinations with diodes are used in inverters. Power BJTs are being supplanted by FETs and IGBTs. FET (Field Effect Transistor): Conducts drain current when sufficient gate voltage is applied. Power FETs (nearly always enhancement mode MOSFETs) have a parallel connected reverse diode by virtue of their construction. Ratings from _1 to _100 A and 30 up to 1000V. Switching times are fast, from 50 or less up to 200 ns. The function applies to dc-dc conversion, where the FET is in wide use, and to inverters. IGBT (Insulated Gate Bipolar Transistor): A special type of power FET that has the function of a BJT with its base driven by a FET. Faster than a BJT of similar ratings, and easy to use. Ratings from 10 to >600 A, with voltages of 600 to 1700V. The IGBT is popular in inverters from _1 to 100kW or more. It is found almost exclusively in power electronics applications. SCR (Silicon Controlled Rectifier): A thyristor that conducts like a diode after a gate pulse is applied. Turns off only when current becomes zero. Prevents current flow until a pulse appears. Ratings from 10 up to more than 5000 A, and from 200V up to 6 kV. Switching requires 1 to 200 ms. widely used for controlled rectifiers. The SCR is found almost exclusively in power electronics applications, and is the most common member of the thyristor family. GTO (Gate Turn-Off Thyristor): an SCR that can be turned off by sending a negative pulse to its gate terminal. Can substitute for BJTs in applications where power ratings must be very high. The ratings approach those of SCRs, and the speeds are similar as well. Used in inverters rated >100 kW. TRIAC: A semiconductor constructed to resemble two SCRs connected in reverse parallel. Ratings from 2 to 50 A and 200 to 800V. Used in lamp dimmers, home appliances, and hand tools. Not as rugged as many other device types, but very convenient for many ac applications. MCT (MOSFET Controlled Thyristor): A special type of SCR that has the function of a GTO with its gate driven from a FET. Much faster than conventional GTOs, and easier to use. These devices are supplanting GTOs in some application areas. POWER CONVERTERS The power processors usually consist of more than one power conversion stage where the operation of these stages is decoupled on an instantaneous basis by means of energy storage elements such as capacitors and inductors. Therefore, the instantaneous power input does not have to equal the instantaneous power output. We will refer to each power conversion stage as a converter. Thus, a converter is a basic module (building block) of power electronic systems. It utilizes power semiconductor devices controlled by signal electronics (integrated circuits) and possibly energy storage elements such as inductors and capacitors. Based on the form (frequency) on the two sides, converters can be divided into the following broad categories: 1. AC to DC 2. DC to AC 3. DC to DC 4. AC to AC We will use converter as a generic tenn to refer to a single power conversion stage that may perform any of the functions listed above. To be more specific, in ac-to-dc and dc-to-ac conversion, rectifier refers to a converter when the average power flow is from the ac to the dc side. Inverter refers to the converter when the average power flow is from the dc to the ac side. In fact, the power flow through the converter may be reversible.

Game Theory (Strategic Thinking in Everyday Life) Have you ever been faced with having to live with a decision you made knowing that had you taken the time to analyze the outcomes you may have made a more intelligible choice? Most likely the answer to that question was "yes". After all that is more - or - less is what life is about, a series of choices and the outcomes we are faced to live with as a result of our decisions. Well your probably asking yourself "What does this obvious statement have to do with me?". I'll begin by telling you it has everything to do with you and everything to do with any situation you may confront from this day forward. After - all life is but a game and it is our goal to win. The fundamentals of the "Game Theory will provide us with the basic tools we need to succeed at this game. What is Game Theory? Simply put, it is the study of rational behavior in situations requiring interdependence. Wow! That seems like a pretty heavy statement. Actually it is pretty straight - forward. What is meant by "rational behavior or interdependance?" Rational behavior in game theory is the assumption that moral critique aside, the players in the game will act in a way which provides them with the greatest benefits.. Interdependence is the idea that what one player does will directly affect the other and vice -versa. By players I am talking about any two interdependant variables, whether they be people, countries, animals etc. Game theorist take apart a situation involving two players and systematically analyze their objectives and their potential outcomes. In doing so they are able to create models which replicate the basic motives each player has and diagram the outcomes.. Game theory is something that to some extent all of us have experience in.

Shakespeares Soliloquies - Hamlet’s Soliloquy Essay -- The Tragedy of

Hamlet's Soliloquy  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚         The purpose of a soliloquy is to outline the thoughts and feelings of a certain character at a point in the play. It reveals the innermost beliefs of the character and offers an unbiased perspective as it is merely the character talking to the audience, albeit not directly, and not to any other characters who may cause the character to withhold their true opinions. Therefore, Hamlet's first soliloquy (act 1, scene 2) is essential to the play as it highlights his inner conflict caused by the events of the play. It reveals his true feelings and as such emphasizes the difference between his public appearance, his attitude towards Claudius in the previous scene is less confrontational than here where he is directly insulted as a "satyr", and his feelings within himself. In this essay, I will outline how Shakespeare communicates the turmoil of Hamlet's psyche.    Hamlet's despair stems from his mother's marriage to his uncle and it is this that is the driving force behind what is communicated. His constant repetition of the time in which it took the two to get married, "But two months dead...yet within a month...A little month...Within a month...most wicked speed", suggests his disgust at the situation and that it is not necessarily the nature of their "incestuous" relationship that troubles Hamlet; more the short time in which it occurred. In fact, this is especially well communicated to the audience as, throughout the soliloquy, the passage of time that Hamlet describes gets less from "two months" to "Within a month". This has the effect of outlining Hamlet's supposed contempt of his mother for only mourning a month whilst also highlighting that it is the time involved that is vexing him a... ...t only through the diction but also through the imagery, language and underlying messages of the text. It successfully highlights the divisions of character of Hamlet whilst aiding the audience in building a connection with him.    Works Cited and Consulted: Boklund, Gunnar. "Hamlet."

Dramatic Importance of Similar Themes Essay

A distinct art form like a poem, novel or play, a short story is a short piece of writing, having few characters, conflicts, a theme, a setting and a point of view, usually fewer than 10,000 words. Every detail contributes to the unity of effect. Most short stories can connect if they include similar elements, characteristics or qualities including character development and themes. In the short stories: A Deal in Ostriches, The Beautiful Suit, and The Triumphs of a Taxidermist, all written by H. G. Wells, there are similar features in the way the author writes about the theme of humans going through major changes in their lifetime, which shows how important this fundamental is in the plot development of a short story. Whether the change is positive or negative; all humans go through many changes that could as well be life altering. In A Deal in Ostriches, this theme is situated to play out a role, so the main character goes through a dramatic change from start to finish, ending with a twist to show the main characters true side. In The Beautiful suit, the main character goes through his major change at the end as well, starting off as a man boy, but dying happily in the end. In The triumphs of a Taxidermist, the taxidermist starts off as a man of an unintelligent nature, but concludes in the founding of an extinct species of a New Zealand bird, showing his true identity. These factors help prove that the consistency of having the same theme, helps plot development and structure greatly in short stories. In A Deal in Ostriches, the theme is showing that the main character goes through a vivid change in his life and role as the story progress to the finish. The main character Padishah, tends to be a loyal character who needs help finding his jewel. We believe he is against Potter, who is trying to steal his jewel for his own contentment. In the end we consider the fact that Padishah changes throughout the story and turns against everyone to be on Potters side. This story concludes with a bit of a twist, â€Å"A week or so after landing I was down Regent-street doing a bit of shopping, and who should I see arm-in-arm and having a purple time of it but Padishah and Potter. †(Wells 4) This shows that even if someone is reliable or trustworthy at the start, it does not mean they will never change. Padishah is a perfect example of how life situations will always change over time. In The Beautiful Suit, the main character is a little man, who goes through a major change at the end of the story, showing the theme of how life changes can occur in very little periods of time. He starts off as a sad man because his mother would never let him wear his favourite suit, but dies happily in the end. â€Å"But his face was a face of such happiness that, had you seen it, you would have understood indeed how that he had died happy. †(Wells 4) He is the one who changes his feelings; he decides to go out and live his life the way he wanted to. One night he decided he was going to do everything he ever wished to do, including wearing his suit. We find out that his negative attitude turned into a positive one just by changing the way he felt he should be doing things. This little man starts his life in a way he did not feel was right, so he took a chance to turn his life around, and he did. He died happily, just as he wished he would. This shows the theme of human life changing noticeably, and how it can also change in an encouraging way. In The triumphs of a Taxidermist, the main character who is a taxidermist starts off hiding who he truly is, but ends up showing how truly smart and sneaky he is in the end. The taxidermist does not tell or show anyone his uniqueness until the end of the story when he reveals that he found a species of a New Zealand bird which is extinct. One man questioned â€Å"Is it one of those big birds recently extinct in New Zealand? †(Wells 2) No one truly believed that the taxidermist actually founded this spices, but life is full of unexpected surprises. If you are gentle and composed, you can always change your ways in life and become a man of great power. The taxidermist showed that humans go through major changes or chose to make those changes themselves, sometime throughout their lifetime. In conclusion all three of these well written short stories by H. G Wells, brought me to the attention that similar themes, such as the theme of humans going through major changes, is very important in plot development of a short story. These short stories all include a main character that goes through dramatic changes from start to finish presenting its similarities. Everything has something in common; you just need to be imaginative to find it out.

The Changing role of women in Britain since 1900

Target 1: How useful is source A as evidence about attitudes towards suffragettes in 1908? Explain your answer using source and knowledge from your studies. The attitudes towards suffragettes in 1908 were mixed; everyone had their own opinions of them. Some people were very supportive on what they were doing and some of them had a very negative response. In source A there is a picture of a ‘suffragette demonstrations in London 1908'. Underneath the source the source it states â€Å"Mrs Emmeline Pankhurst leading a demonstration which 200,00 people are said to have attended.† This source does not give enough evidence to prove this statement. I explain why. In this picture it shows me the suffragettes having a peaceful demonstration they are smiling and at the same time getting what they want to say across, from my knowledge and understanding suffragettes were seen as violent and they were seen as a very confrontational group. In the source booklet under The WSPU- the suffragettes it tells me that In 1903 Emmeline Pankhurst and her daughters formed a breakaway group called the Women's social and political union (WSPU), that was to campaign for the parliamentary vote for women on the same terms as it was granted to men, or would be in the future, their motto was â€Å"deeds not words† yet the photo paints a different picture. In source booklet source 6 under Suffragette tactics it tells me that in 1908 the suffragettes would start occasional attacks on properties such as breaking windows, etc. But yet again from source A I cannot see this. The source also states, â€Å"200,000 people are said to have attended† From source A it seems to me that at least only 1,000 people attended. In this source I can see only one policeman and he looks quite peaceful and undisturbed. If this were a demonstration where 200,000 people are said to have attended there would be hundreds of policemen on sight. This photo is very unreliable to its statement. The source says that Ms Pankhurst lead the campaign yet there is no proof to prove this. This is supposed to be a demonstration but from my understanding a demonstration is 1) an outward showing or feeling. 2) A public meeting or a march for political or moral response. 3) A show of military force. If this was a demonstration you would have seen exactly what they were demonstration from the use of banners and posters or even photos but I cannot see any of this. This photo (source A) is very unreliable and does not give enough evidence to represent that it was a suffragette demonstration in London 1908. This source is not useful evidence about suffragettes in 1908. Target 2:Source D and E are both from 1910, yet they give different views about the campaign to gain women the vote. Which is the most reliable source for investigating people's attitudes in 1910 towards the campaign? Source D is an article from the daily sketch (newspaper) in 1910. It is about a demonstration made by women in 1910. This article is anti-suffragette; it's against women for what they are doing. This article is about a suffragist attack on the House of Commons. The title â€Å"DISCRACEFUL SCENES†, and â€Å"120 arrests† gives you a dreadful view of the suffragettes. This source is also very negative against women because it puts them down. In the first passage it states â€Å"they caused even more violent scenes then before†. This gives you the impression that they were always violent and aggressive and that's all they were good for. Also in the first passage it states â€Å"It was a picture of shameless recklessness†. This makes the women look disgraceful and outrageous. In Passage two the first four lines say, † One campaigner sprawled in the mud to the obvious disgust of decent men and the obvious delight of others†. This gives me the idea that some people found it a revolting and thought they were shameful, but yet some people saw it a something very positive. This source is very negative towards the suffragettes and makes them appear violent and shameful. This really affected the way people viewed the suffragettes. Source E is in favour of the suffragettes and are for the vote for women. This source is a postcard issued by the suffragettes in 1910. This postcard shows what a women may be, such as a mayor, a mother a doctor or even a teacher and still not have vote, then goes on to show what a man may be, such as a convict a lunatic, unfit for service or even a drunkard but yet still get the vote. Women were put in a lower category then these types of men; Suffragettes saw this as an insult. However I feel that both Source D and Source E are very reliable for investigating people's attitudes towards the campaign, but I think the most common attitude towards the suffragettes at that time was Source D. Source D gives the most relevant information and is the most reliable source because these were the negative attitudes shown towards the suffragettes at this period of time. The community didn't like to see women behaving as men or behaving inappropriately it made them look bad. This source investigates the minority of people's attitudes towards suffragettes in 1910 but at the same time remains relevant for the investigation of people's attitudes towards suffragettes in 1910. Target 3: Without the First World War women would have not gained the right to vote in 1918†³ Do you agree or disagree with this interpretation? I agree with this interpretation. I believe that women would have never gained the vote without the First World War. So many men had gone of to war that the women were needed to fill their places this increased the number of women in the industry. The war made it adequate for women to work such jobs. People believed that women shouldn't be prohibited from doing work they are fit for. While the men were sent of to war, women showed how equally they worked to men, the leaders saw this as an opportunity to show what women were capable of, they showed how capable they were of doing what was seen as a man's jobs. The suffragettes broke the stereotype of how people viewed women, women were seen as housewives, they stayed home and cook and look after the kids. Men also thought that they didn't have the intelligence or intellect to do a â€Å"mans job†. In Source 27 on the source sheet written by E.S. Montague, Minister of munitions, in 1916 he states that: â€Å"Women of every station†¦. have proved themselves able to undertake work that before the war was regarded as solely the province of men†¦. Where is the man now who would deny women the civil rights which she has earned by her hard work?† Women were showing themselves how equally skilled they were to men, and that both sexes were equally alike. People started to see the women as people that played a likewise part in society as men and that they deserved the vote. People believed that the women earned their rights through their hard work. In Source 29 on page 68 it also state that: â€Å"†¦ Many women had witnessed the suffering and anguish of men of men as they had not seen in the previous wars and had also worked side by side with comrades and friends. It was inevitable that this would start to change mutual perceptions of and the granting of the votes at last (to women over thirty) seemed totally appropriate.† This gives me the impression that people did see the women working really due to the war and did all they could to gain the vote and the only resort and the most appropriate was to give them the vote. In Source 19; Page 66 we are shown a female tram driver it does not give us a date but it shows it shows us that women were enthusiastically involved in a man's role. This acts helped change the way people viewed suffragettes. Before most people attitudes were biased towards giving women the vote, but after the war people attitudes change and However in 1918 the barrier against women's suffrage was broken and a partial victory won, under the Representation of the People Act, women over 30 years of age were given the parliamentary vote if they were householders, the wives of householders, occupiers of property with an annual rent of à ¯Ã‚ ¿Ã‚ ½5 or more. About 8.5 million women were put under this new law. It was not until ten years later, however, that all women could vote on equal terms with men, at the age of 21 and over, the new bill becoming law on July 2, 1928.
