Sensors and Control Systems (Electrical and Electronic Engineering) - Lab Report Example Rotating a DC electric motor’s rotor like tacho generators will produce electricity and voice-coil speaker can also act as microphones. It consist of a nickel wire of 0.5-1 mm diameter kept stretched between the poles of a permanent magnet and having a small stylus rigidly attached to it at the mid-point. The wire is prestressed by twisting it, before being installed into the position. Two pick-up coils of fine wire are wound round the wire on either side of the mid-point. Any displacement of the stylus to one side or the other increases the torsion on the side and decreases it by an equal amount on the other side. This results in an increase of magnetic flux in one-half and a decrease in the other half. The corresponding induced emfs are in phase opposition and are processed by suitable networks as in the case of linear variable differential transformer. It is used as phonograph pick-up and is designed to have flat frequency response over 150 Hz- 15 kHz frequency range. Due to the nonlinearity and hysteresis in the performance, it is normally limited for use when time- varying torsions of small amplitude are to be measured. It was discovered in 1879 and belongs to one of the galvanomagnetic phenomena in which the interaction between the magnetic field and the moving electrical charges results in the development of forces that alter the motion of the charge. When an external magnetic field is applied to the current carrying hall element perpendicular to the current flow a Lorentz force acts on the current due to which a voltage called hall voltage is generated perpendicular to both the current and the magnetic field. This voltage is so small and needs amplification. If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the

Malcolm X and Martin Luther King Jr Essay The PBS video, â€Å"Malcolm and the Civil Rights Movement† is important in showing the varying views of both Malcolm X and Martin Luther King Jr. The video makes it well evident that both men were striving for the same end result, which was â€Å"defeating white racism and empowering African Americans. However, as the video explains, while both men had the same destination in mind, they both sought different journeys to get there. Through an analysis of the PBS video, Martin Luther King Jr.’s â€Å"I Have a Dream† speech, and several passages from The Autobiography of Malcolm X, it can be concluded that while the two men wanted the same thing, they both had different views and beliefs; Malcolm X was angry, bitter and vengeful, while Martin Luther King Jr. was only concerned with fixing the issue at hand. Early in the PBS video, it is explained that while King wished to mend and strengthen a family bond that already existed, Malcolm X viewed himself and black Muslims as an outside party. This is evident through the public denial that Malcolm X was even an American due to his opposing view of the suggestion of â€Å"integration with white America.† (â€Å"Malcolm and the Civil Rights Movement†, The American Experience. PBS. Video Transcript) This belief that Malcolm X was completely angry and against white America is aided though a passage in his autobiography coming from page 292 of the fifteenth chapter. In the first provided passage of Malcom X’s autobiography, Malcolm X shows marked bitterness and hatred in his choice of words to describe the situation. This can best be attributed to the quoting of the his words saying â€Å"the antebellum white slavemaster even devilishly manipulated his own woman.† This phrasing by Malcolm X speaks volumes to how he views the relationship of the white male to the rest of society. Through the using of the word â€Å"devilishly† he is portraying his inner thoughts that the white man is evil and c orrupt in his judgments. Then by using the words and â€Å"manipulated† and â€Å"own†, Malcolm X is expressing his belief that the white man is power hungry and sees the world as a game for his bemusement and handling. Furthermore by saying â€Å"his own woman†, this would suggest that Malcolm X believes that the white slave owner sees himself the master of not only black men but also white females. (Malcolm X, p. 292) To the slave owner, everything but himself is property and assets to be owned and managed. The passage then goes on to explain that Malcolm X strongly holds a general stereotype of slave owners copulating with their slaves to be unquestioned fact about all slave owners. His remarks that the slave owner has conned his wife into letting him procreate with the slaves allows valuable insight into Malcolm X’s thoughts that white male is purely a trickster and untrustworthy. The final two paragraphs of the first passage provided from The Autobiography of Malcolm X offer perhaps the most profound description of Malcolm X’s beliefs surrounding the relationship between blacks and whites. Through the anecdote of the girl traveling all that way to try and make amends for something that not even herself has been proven guilty of showcases how impenetrable Malcolm X’s beliefs are. While the girl asks Malcolm X if he believes â€Å"there are good white people†, Malcolm X explains that only actions can change his thoughts. The girl then offers, â€Å"What can I do?† at which Malcolm X responds that there is nothing she can do (Malcolm X, p. 292). This effectively renders the argument that Malcolm X firmly believes that the previous and current disrespectful actions whites have shown blacks are unforgiving. This belief and anger strongly contradicts with the first part of Martin Luther King Jr.’s â€Å"I Have a Dream† spee ch. Martin Luther King Jr. begins his speech with a preface of â€Å"let us not wallow in the valley of despair,† which he uses to say that the past does not need to define the feelings of the future. King then addresses that by moving on from the past quarrels, brotherhood can be established and the nation’s creed of â€Å"all men are created equal† can be recognized (â€Å"Martin Luther King: I Have a Dream† 1963. Speech). Paralleling this theme of the past not defining the future, King speaks of the state of Mississippi’s current and previous mishaps and how it can change as long as the past is left in the past. In the second provided passage of Malcolm X’s autobiography, which is pages 250 and 251 of the fourteenth chapter, it becomes increasingly clear that Malcolm X does not believe that whites and blacks can live happily on the same level. He then makes a unique distinction between the words segregate and separate. Through a reference to Elijah Mohammed, Malcolm X explains that segregation implies that one side –blacks– are inferior to the other side, while separation suggests that both sides have mutually agreed to part ways and keep distance without one holding significant power or influence over the others. To round out the passage, Malcolm X makes an analogy to a mother and her child stating that unless the baby is separate at birth then both the mother and baby will ultimately die (Malcolm X, p. 250-1). Interestingly, in the third provided passage, which is also found in the fourteenth chapter on pages 260 and 261, Malcolm X makes an interesting comparison of the black people being pets of the white society. This shows that Malcolm X believes that blacks are being trained for the benefit of whites and even mentions the word â€Å"brainwashing† to describe how whites have affected blacks. This passage continues the thought from the second provided passage from earlier in the chapter that blacks should be given the chance to be their own people, away from the influence of white society (Malcolm X, p. 260-1). This analogy suggests that Malcolm X sees the black peoples as independent people that deserve the chance to grow and mature on their own terms. Differing strongly from Malcolm X is King’s speech which showcases his believe that separation is not needed and that he envisions both races coming together as a family. This is illustrated through the line â€Å"black boys and black girls will be able to join hands with little white boys and white girls as sister and brothers.† With reference to his reverend background, King makes a suggestion that religion can be a unifying factor for the two races and that â€Å"the Lord shall be revealed and all flesh shall see it together.† (â€Å"Martin Luther King: I Have a Dream†, 1963. Speech) This is in direct contrast to Malcolm X and his autobiography, which puts significant emphasis on his Muslim beliefs being in direct opposition to white society. With the religious tone set, King’s speech then continues to explain how the previous grievances and tragedies of yesterday can be removed for tomorrow beginning with the phrase â€Å"with this faith†. This explains that King was looking to mend fences while Malcolm X saw the situation as â€Å"us versus everyone† and that everyone was out to victimize them. Finishing his speech, King expands the current situation to encompass the hardships of all other situations in the United States. Through this, King is able to offer that uniting of the black and white races can be a foundation for freedom of all parties in the United States. This helps to explain the difference between the views King and Malcolm X most clearly. While Malcolm X believes that unless separation is achieved the two races will destroy each other, King believes that if the two races come together then great achievements and progress in freedom for all can be accomplished. The PBS video then explains that Malcolm X did not want the black Muslim people to viewed as â€Å"defenseless† and thus, he was opposed to a strategy of non-violence (â€Å"Malcolm and the Civil Rights Movement†, The American Experience. PBS. Video Transcript). Because of the differing views on violence, religion was brought into play and Malcolm X insinuated that King was following the white man’s religion and still being controlled by him. While physical violence was avoided by King’s strategy, so was verbal assault as King often avoided criticizing Malcolm X and his comments. The video then explains that Malcolm X’s unique position then became less dominant in his mind as he felt let down from Elijah Muhammad after the death of Ronald Stokes. At the same time Malcolm X was looking to cause physical pain to the other side, King was making legislative and social gains in his movement (â€Å"Malcolm and the Civil Rights Movement†, The American Experience. PBS. Video Transcript). This helps to explain that King largely wanted a fix to the problem, while Malcolm X wanted revenge. Through an analysis of the PBS video, Martin Luther King Jr.’s â€Å"I Have a Dream† speech, and several passages from The Autobiography of Malcolm X, it can be concluded that while the two men wanted the same thing, they both had different views and believes. Malcolm X can be concluded to be angry, bitter and vengeful, with no believe that the relationship between blacks and whites could be salvaged. While differing greatly, Martin Luther King Jr. can be said to be guided by faith, optimistic, future oriented and only concerned with fixing the issue at hand. Works Cited 1.King, Martin Luther.

Work Teams: Dispute Resolution Abstract Can conflict among work teams or individual employees be avoided? This and other conflict resolution issues will be addressed in this paper along with a couple of hypothetical workplace disputes and the viable solutions that can be applied to resolve the conflict(s). Work Teams and Conflicts   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The use of work teams has become a popular strategy for increasing productivity and worker flexibility in the United States. Seventy-eight percent of U.S. organizations report that at least some of their employees are organized into work teams. In those organizations that utilize teams, an average of 61% of all employees is members of teams† (Bishop, Scott, and Burroughs, 2000). â€Å"A team is a group of people who are interdependent with respect to information, resources, and skills and who seek to combine their efforts to achieve a common goal† (Thompson, Aranda, and Robbins 2000, p9).   Ã‚  Ã‚  Ã‚  Ã‚  In most cultures and most global organizations, individuals have been paired or grouped into teams that are required to work together towards the completion of set goals. Today’s employees come from diverse cultural backgrounds with diverse attitudes and values. This can be good in that it can provide an organization with new and innovative ideas for positive and profitable direction in a global economy that is dominated by many of the same types of businesses. However, when employees are placed in groups or work teams, conflict can, sometimes, arise. Types of Hypothetical Workplace Disputes   Ã‚  Ã‚  Ã‚  Ã‚   Conflict can be good or bad for an organization. It is good or functional when it causes a team to perform effectively. However, conflict can be bad for an organization when it causes a group or team to perform inefficient and ineffective work that keeps the team from achieving its desired goals and objectives in the specified timeframe. Some conflicts support the goals of the group and improve its performance; these are functional, constructive forms of conflicts. There are also conflicts that hinder group performance; these are dysfunctional or destructive forms (Robbins 2001, p262-263). What Causes Conflicts   Ã‚  Ã‚  Ã‚  Ã‚  Several factors can lead or contribute to the escalation of conflict among groups or teams in the workplace. Some factors include but are not limited to: communication barriers, lack of good interpersonal skills, and poor ethical behavior. Desired Outcomes   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Conflict is constructive when it improves the quality of decisions, stimulates creativity and innovation, encourages interest and curiosity among group members, provides the medium through which problems can be aired and tensions released, and fosters an environment of self-evaluation and improvement† (Robbins 2001, p269).

Written Rational of Negotiating with Learners

Written rational of negotiating with learners, understanding inclusive learning, how to integrate functional skills and how communication can be delivered to the learner Teaching is based on many different ideas which all come to gether to help create and deliver a session to a group of learners. It is important to understand how, communication, inclusive learning, functional skills and negotiating with learners can lead to effective learning.Planning teaching and sessions can enable all learners to have the same opportunities to learn equally and will help the teacher to achieve their learning objectives. Negotiating with learners Assessment should be used for teachers as well as learners Life long learning UK (2007) Assessment is a valuable tool for both Teachers and learners to assess how and whether learning has occurred, according to Scales (2008) The principle purpose of assessment is to help people to learn; it should not be about testing people to see at what point they will fail.It is a method of elevating learners to a higher level of learning Everett (2012) Initial assessment occurs at the beginning of the course or precourse to obtain information about the learner’s skills and knowlage to date. Formative assessment helps the teacher to see how learners are progressing before moving on to other topics. It includes the effectiveness of the teaching and learning-taking place. Summative assessment is carried out at the end of the module or the course to assess whether the learning objectives have been achieved this can be via an exam.Other Methods of assessment include the following, *Observation * Simulation * Project and assignment * Portfolio * Written questions (essays and short answers) * Verbal or oral questions * Professional * On going assessment * Questions and answers * Assignments * Debates and discussions Initial assessment should help agree goals between the learner and the teacher; it is god process to help ensure the learner feels supported and happy. Inclusive learningInclusive learning Is about recognising that each learner is if different and each learner will require different information or aids to help them learn, it is about understanding that no one learner should be excluded from any activities within any session. In terms of learning this is where the teacher can really empower their students. According to Petty (2009) Inclusion, diversity, entitlement, differentiation, ensuring equal opportunities and personalized learning require teachers to treat students as individuals.When planning sessions it is important that the teacher plans for inclusion, an effective way to do this is to make sure session plans are written beforehand and â€Å"includes methods that appeal to visual, auditory, and kinaesthetic learners† Wilson (2009) Sessions should follow a structured style, that includes a introduction, middle and end, it should also include lots of interaction between the teacher and the class, b ut also make sure there are lots of things to do such as quizzes, visuals (PowerPoint) and games.The teacher should also analyze the class as it progresses to make any needed changes but also make an effort to make sure everyone in the class feel included. â€Å"Support your less able learners and stretch the imagination of the gifted ones† Wilson (2009)The Use of different resources to help each learner get the most from the session is important, aim to be creative with your learners, if there is a lot of talking in a planned session create hand outs to aid visual learners to help them follow, a great way to invite kinaesthic learners to learn is to give them hand outs and ask them to fill in blank words as they go though the session, by making sure the session is varied and has lots to do ensures that the needs of VAK are being met.Great resource openers, fillers and closers include word searches, quizzes, and crosswords can be given to those learners who are quick to finis h or for those who need an alternative exercise. Communication Communication is a means of passing on information from one person to another; it can be verbal, non-verbal or written Gravells (2008) Communication is generally in one of three ways; 1. Written – this can be long hand, short hand, text, images 2. Verbal – spoken, direct face-to-face or indirect on the telephone 3.Non-verbal, also know as body language – dress, facial expression, Proximity, and touch. In any communication exchange, the teacher should ensure that what has been offered has been understood. Pausing to summarize the things that have been spoken and heard can do this, and by asking questions to get feedback from learners to make sure they have understood and comprehended the topic. The key with any communication understands the message, which is being conveyed which can be done via questions and answer sessions, quizzes, questionnaires, feedback sessions.For communication to be effective the teacher needs to understand the intrinsic barriers to effective communication these can include the following: * Jargon and specialist terminology – write specialist words or info On the board so learners understand * Level of language depends on age of the learner be mindful when Developing hand outs so learners understand * Language and accent- speak clearly and slowly * Noise background noise can be distracting, fans, computers outside Noise * Listening and writing some people can not write and listen at the Same time, time should be given for note taking Talking and listening- speed, timing and allow for thinking time Integrating functional skills Functional skills are an initiative that was devised by the government to standardize qualifications in English, maths, and ICT. Functional skills are also known, †¢ Basic skills †¢ Common skills †¢ Key skills †¢ Core skills However they are now known as functional skills and these refer to the mastery of English (lit and language), maths (numeracy) ICT (info technology) These are the skills that underpin all learning and without them learners will struggle to meet the needs and demands of their chosen qualification, work and life skills.Government 14-19 education and skills white paper employers have identified functional skills as vital skills to learning, and functional skills can be taught in any class setting. English/ Literacy – spelling competitions – Discussions – Presentations Maths – – real life skills – Calculations – Interpreting and presenting results ICT – finding and selecting information – Entering and developing information.Embedding functional skills means that English, maths and ICT are delivered within any session in a clear concise way with out the learner realising it is being taught. â€Å" Integrating functional skills into your teaching means that you will set activities which meet the literacy, or numeracy standards; they may or may not be in context. By incorporating functional skills into every activity they will become embedded† Wilson (2009) Integrating functional skills is essential for helping learners to achieve and succeed in the future.Learning should engage, motivate and enthuse each learner on an individual basis, this means the learners individual needs should be considered and language, literacy, and numeracy skill levels should be considered, teachers should make sure each learner is taught in a way that they feel engaged, respected, safe, secure, and valued. Teachers should seek to use communication strategies that are within the learner’s range of understanding to motivate them.Wilson (2009) suggests that teaching and learning strategies should vary according to how the teacher will engage and support the learners within the time allowed, by using a range of learning methods, materials and resources each learner will feel included and supporte d with in the learning environment.

Human Impact of Climate Change Essay

Climate change concerns to a statistically momentous deviation in either the mean state of the climate or in its variability, remaining for an extensive period (normally decades or longer) (What is climate change, 2001). Climate change is term that adverts to any major and long-term change in average weather in a specified region or whole Earth. Fundamentally important variability of average weather over longer time period can be depicted as climate change. Climate change is due to natural internal procedures or external pressures, or to relentless anthropogenic alterations in the composition of the atmosphere or in land utilization. Earlier in the beginnings of Earth’s history climate changes were normally induced by different vibrant processes on Earth but recently it is caused by human activities. This is the reason that in our everyday talks the term climate change refers to climate change caused by global warming. The most disposed signs of climate change are glaciers that are presently melting at rapid level which entails climate change has already began. This time, climate change is only due to the recent human activities and had resulted in global warming process. Today, Global warming has become synonym for climate change due to its role in climate change. Undue emission of injurious greenhouse gases into atmosphere is causing a raise in average temperature that in turn is affecting the climate on Earth (What is climate change, 2001). The use of fossil fuels as a dominant aspect is continuing to emit CO2 and other greenhouse gases into atmosphere that is causing even more grave effects to climate change. With the rise in temperature globally effects like severe changes in weather patterns, climbing sea levels and increasing frequency and intensity of extreme weather is been experienced. The world’ most susceptible areas are around Earth’s poles and Africa and these areas had already started experiencing momentous increase in average temperature. The depressing fact is that one can’t stop climate change and can only make attempt to adjust to it and not making it worse with its own activities. Our own activities induced global warming and at this time all of us are confronted with the climate change as our most prominent environmental challenge. Although, all of us are already aware of climate change but still lacking in our activities to stop further increase of greenhouse gases in the atmosphere. For dealing with this present environmental challenge, there is a need to work vigorously for a global agreement to control climate change and to take possible domestic actions to attain satisfying diminutions in our own contribution. Discussion Significance & Scope of the Issue The management of the severe environmental challenge is essential as otherwise it could direct us towards drastic results. Already climate change is responsible for 300,000 deaths a year in accordance to former UN secretary general Kofi Annan’s think tank, the Global Humanitarian Forum. The study generated by the Global Humanitarian Forum also claims that approximate 300 million people in a year are affected by the outcomes of climate change (The Human Impact of Climate Change, 2009). Climate change is not only an all-encompassing menace but it is also an arbitrary threat-multiplier. With the affects of climate change a number of vulnerable communities of this planet can get destroyed (2009 Forum-Human Impact of Climate Change, 2009). The devastating effects of our development and measures for national, regional and global security are not measurable presently, but slowly or gradually its affects will start appearing along with destruction. The different studies done in this field projects that the increasing severity of events, like flooding and storms due to climate change will be accountable for approximately 500,000 deaths a year by 2030. Currently climate change is stimulating losses of over $125bn a year that is greater than the last year total of world aid. Anticipations exhibit that by 2030, losses could be around $600bn a year. With this weather related disasters problems like hunger, disease, poverty and lost livelihoods can increase (The Human Impact of Climate Change, 2009). If within coming 25 years, emissions are not brought under control the 310 million more people will start suffering with unfavourable health consequences connected to temperature gains, 20 million more people will fall under poverty and 5 million more people will be expatriate by climate change (The Human Impact of Climate Change, 2009). These statistics regarding the effect of climate change demonstrates that in present this is most significant environmental challenge that the world is facing. This need to be managed as soon as possible for everyone as otherwise it could lead to pressurize food production, decrease sanitation, and block economic development and degradation of ecosystems. Specific causes of Climate Change Climate change is the result of both the natural and human factors, but from some past decades it is mainly due to the subsequent human factors: †¢The most prominent reason of climate change is releasing of greenhouse gases and aerosols into the atmosphere. From last two hundred and fifty years, the concentrations of greenhouse gases and carbon dioxide have increased due to the burning of fossil fuels for energy production. The more the countries are moving towards industrialization and development, the more they are affecting their environment, which is resulting in the climate change (Climate Change, n. d. ). †¢Another prominent reason of climate change is deforestation, which is related with agriculture and urban development and harvesting timber for fuel, construction and paper. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). †¢Sulphate Aerosols and Black Carbon are other two crucial instances of anthropogenic forcings. Current industrial activities have recently increased the concentration of sulphate aerosols and black carbon in the atmosphere that is making imperative effect on our climate in the form of drastic weather events. Critical Analysis & Evaluation of Environmental and Ecological Consequences Earlier, the Earth’s atmosphere was changed very little. The temperature and the equilibrium of heat-trapping greenhouse gases were appropriate for humans, animals and plants to stay alive but presently everyone is confronting problems in maintaining the balance due to increasing industrialization and development activities. For our own comfort of life and economic development, all of us are making increasing use of fossil fuels from heating our homes to creating energy. This is adding more and more greenhouse gases to the atmosphere that in turn is raising the warming potentiality of the natural greenhouse effect. This enhanced greenhouse effect is causing environmental and ecological concerns as it has the potency to warm the planet at a range that has never been went through in human history. This warming of the climate is resulting in more extreme weather patterns, chances for several ecosystems to adapt naturally are decreasing, sea levels are rising, glaciers are melting, ocean acidification is increasing and agricultural outputs are ailing resulting in hunger. All these consequences are related with the use of fossil fuels that is the significant reason for CO2 emissions. The use of fossil fuels in turn is closely linked to economic growth, lifestyle and our culture. In present every human being is contributing to the CO2 concentrations in the atmosphere (Climate Change, n. d. ). Though, the person’s lifestyle and culture determines the amount emitted by him. The more flourishing a country’s economy is the superior is its fossil fuel consumption, ensuing in higher greenhouse gas emissions. Success of Solutions’ Proposed & Applied Climate change is affecting the whole world. Number of developed and developing countries are working together to discover the solution of environmental challenge of climate change. From the time, this issues has emerged a number of efforts had been done some of which had attained success and some had failed. In June 1992, 154 countries signed the United Nations Framework Convention on Climate Change (UNFCC) that corresponded to alleviate the amount of greenhouse gases in the atmosphere at levels that would not cause destruction. In Kyoto, in December 1997, Japan, Canada and 160 other industrialized nations committed to cut down their greenhouse gas emissions, as component of an international agreement on climate change identified as the Kyoto Protocol. This eventually came into force throughout 2005. Till the time these efforts had not attained immense success but with these efforts modest emission reductions had been encountered from industrialised countries. Countries are trying to reduce their emissions as now they had become aware with its severe results. Conclusion With the detailed discussion it can be said that in present climate change is with us. A decade ago, it was only an assumption but currently the future is unveiling before our eyes. Canada is experiencing it in the form of vanishing Arctic ice and permafrost. Latin America and Southern Asia is seeing it in lethal storms and floods whereas Europeans are experiencing it in melting glaciers, forest fires and disastrous heat waves (Pearce, 2006). All these experiences of different countries disclose that the consideration regarding this environmental challenge is imperative as otherwise more and more countries of the world will start experiencing its effects. The present rastic change in the climate needs to be controlled for assuring an appropriate level of CO2 concentrations in the atmosphere as otherwise it could bring unpredictable changes in our environment and ecological system. For controlling this environmental challenge staying educated about climate change and supporting attempts to deliberate its progress are the things that everyone can do and should do. Our ef forts regarding the climate change could make our economy more internationally competitive by creating expansion and jobs while raising less waste, pollution and greenhouse gases.

Its a Mans World Essays

Its a Mans World Essays Its a Mans World Essay Its a Mans World Essay Where do women stand in a mans world? It is a mans world. Men are higher paid, have more options and are overall more noticed in the world than women. But this is not to say that women are left flailing away helplessly at the bottom of the gender food chain or hidden somewhere in the shadows or mans success, because many would argue those mens lives are greatly dependent on women. It is a well known fact that men in general have been known to achieve to a much higher standard than women in the financial world. The top 15 billionaires are all ale except for one female who inherited the money from her belated husband. While these men sit comfortably at one end of the spectrum, many women are located at the complete other end of the extremes occupied by unpaid work. Unpaid work is known to women all over the world from women collecting wood and walking kilometers to find water in Africa to cooking and cleaning in households Just like our own. However, because this type of work does not produce any financial profit alone it is often considered economically redundant and worthless. The truth is that this mind of work is essential for the workings of the rest of society and the existence of the paid work force itself. In 1999 unpaid work was calculated to be valued at 40 million dollars which was equivalent to 39% of the NZ gross domestic product and in 2006 a New Zealand survey showed that women are still more likely to do unpaid work than men. This type of work may be taken up time that could be used to do paid work, but it is this kind of work allows others to get out of the house and do paid work which is why mens financial success is greatly dependent on women.

Past-Tense Regular Verb Pronunciation Guide

Past-Tense Regular Verb Pronunciation Guide A language thats always changing and adding new words, English is a challenging one to learn, as it is full of quirks and exceptions. The construction of regular past-tense verbs, at least, is pretty straightforward. It is generally done by adding -d or -ed to the verb, and it doesnt change form based on the subject of the verb: I asked, he agreed, you accepted- the verbs in these instances all look alike, ending in -ed. What does differ between them, though, is the  pronunciation of the ending. For some verbs, its a voiceless sound like T, as in asked; in some, its a voiced sound of D, as in agreed; and in some, its pronounced like ID, as in accepted. The lists that follow are three groupings of regular past-tense verbs, based on their pronunciation of the ending.   Note:  When you are looking at sentences to find the verbs to change to past tense, be certain you have found the verbs.  Theyre the action words. Group A:  Voiceless Last Sound of the Infinitive If the infinitive of the verb has a voiceless sound at the end of it, such as p, k, s, ch, sh, f, x, or h, you pronounce the ed ending as a T. (Note the pronunciation in parentheses. Its the sound that determines the group that a word belongs to, not always the written letter. For example, even though dance ends with a -ce, its sound is that of an s, so its in this voiceless group.) Example: Ask, asked ask(T) -ed as â€Å"T† askedbakedbrushedcookedcrackedcrasheddanced (da:ns) tdresseddroppedescapedfinishedfixedguessedhelpedhikedhopedjokedjumpedkissedknockedlaughed (là ¦f) tlockedlookedmissedmixedpackedpassedpickedpressedpronouncedpushedrelaxedshoppedslippedsmokedstoppedtalkedtypedwalkedwashedwatchedworked Group B:  Voiced Last Sound of the Infinitive If the last sound in the  verb is a voiced one, such as in l, v, n, m, r, b, v, g, w, y, z, and vowel sounds, or diphthongs, then pronounce the -ed ending as D.
