Two Kinds by Amy Tan free essay sample

The story takes place around 1960’s, where the narrator talks about her childhood and 1980’s towards the end when she had grown up to be an adult about thirty years old. In the sixties, many Chinese immigrants came to America to persuade their American Dreams. â€Å"American dream† was first attributed in James Truslow Adams’s 1931 book The Epic of America, where he refers the dream as â€Å"a dream of a land in which life should be better and richer and fuller for everyone, with opportunities according to ability or achievement. † Another key aspect of the dream is freedom, the freedom to pursue happiness in life in this new world. The conflict between Jing Mei and her mother represents the conflict of the two generation of Chinese immigrants in pursuing their American Dream. The first generation, Jing Mei’s mother, who suffered hard life in China before coming to America, emphasized more on survival in her dreams, such as to open a restaurant, to buy a big house, to be rich and famous, whereas, the daughter, who was born in the new land, never go through the hardship of life like her mother, believes in her dream of being happy, free, and most of all, being just the way she is. We will write a custom essay sample on Two Kinds by Amy Tan or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Jing Mei’s mother lost everything in China including her twin daughters before she came to America. She believes in the American dream of success and tried her very best to turn Jing Mei into a famous prodigy. She works hard to provide her daughter ways to success. She took her to beauty training school to have her hair styled, took dozens of magazines from the houses she cleans so that Jing Mei could be knowledgeable and even provides free house cleaning for her piano teacher in exchange for her piano lessons. Her strong and willful character is well represented the first generation Chinese immigrants. Instead of lamenting over the hardship she had in China, she moves on to create happiness and success in the new land. She was confident that her daughter can be a prodigy if only they can locate her talent and nurture it well. Unfortunately, her effort leads to a deep resentment in Jing Mei. The protagonist and narrator, Jing Mei is the American-born daughter who struggles with the burden of failing to meet her mother’s expectations. She tells the story of her childhood under the pressure of her mother who kept trying to make her a famous prodigy. Although Jing Mei was excited about her mother’s plan at first, as time goes on, when the tasks got harder and harder, she failed to achieve them. Many times, after seeing her mother’s disappointed face she felt â€Å"something inside her began to die†. This shows that in she loves her mother and was afraid to see disappointment in her mother’s attempt to find her talent. Jing Mei lost her confidence and decided not to response to her mother’s effort in nurturing her. Jing Mei’s mother holds on strongly to her Chinese culture. She always uses Chinese language when she speaks to her daughter. She said, â€Å"Ni kan,†¦Ã¢â‚¬ ¦. † But she did not realize that in her way of pursuing her American dreams, she sacrificed her own culture. She forced her child to read Western magazines, she sent her to church and made her memorized the bible. By doing so, she created a culture difference between the two of them which leads to many misunderstanding. Being born in America, Jing Mei had a very independent behavior but her mother thinks that she is disobedient. This shows the difference perceptions of the two generations and they do not share the same views on things. Jing Mei struggles to find her own sense of identity against her mother’s wishes and feels that she can be successful through her own effort and determination. She felt that her mother was trying to control her and decided to do things her own way. The situation worsened when both of them failed to communicate with each other. They never listened to each other, and ended up being further apart. She was determined and tried many ways to annoy and displease her mother to end her domination and control, but her mother continued to push on. At last her mother gave up on her when she hurt her by saying that she wished she was dead like the twins she left behind in China. At the end of the story, Jing Mei realized her mistakes after her mother passed away and gave her the piano as a memory. Jing Mei thinks that her mother’s criticism are signs of lack of affection, but the fact is, her mother’s severity and high expectation are the results of her love and faith in her daughter. The mother’s traditional Chinese values of filial obedience, criticism-enveloped expressions of love, and concealment of excessive emotions clash with the daughter’s American ideas about autonomy, free and open speech, and self-esteem. However, as Jing Mei grown up as an adult, she ultimately reconciles some of these cultural and generation differences. Like all mothers, Jing Mei’s mother forgave her hurtful words and offered her the piano on her thirtieth birthday. When Jing Mei played the piano for the first time since childhood, she noticed the piece on the page opposite from the â€Å"Pleading Child† is called â€Å"Perfectly Contented†. She gets to realize that â€Å"they were two halves of the same song†. The names of the two- parts song are very ironic. Despite the differences of Jing Mei and her mother, they were like the songs, they may disagree but they made one stunning song. The song symbolized Jing Mei’s life. During her childhood, she had felt dissatisfied with her life and with the choices she was forced to make. As an adult, when she was offered the piano, she knew that her mother had forgiven her. Therefore she had found her inner peace. She had reconciled the issues of her failures and knew that her mother never considered them failures. It was just the love from a mother that she had for her daughter. Although Amy Tan tells the story of an American Chinese experience, the issues in Two Kinds are universal because the story explores themes of family, their relationship as well as the conflicts of culture which are applicable to all people disregard with their nationality, religion or race. Such themes actually apply to Asian families as well, as love and affection is universal. References: 1. TAN. A, The Joy Luck Club, New York: Ivy Books. 1989, pg 132-148 2. Huntley, E. D.

Miracles of the Quran Essay Example | Topics and Well Written Essays - 1250 words

Miracles of the Quran - Essay Example It was revealed piecemeal to him in twenty three years, starting from when he was forty, till he died at the age of sixty three. The book was not compiled during his lifetime, with many Muslims memorizing it by heart; some years afterwards, a lot of these memorizers, or Hafiz, were killed in battle, therefore, the Muslim Caliph Usman decided to get it compiled. The compilation of Quran in its present form was, hence, done under the Caliphate of Usman. The Muslims believe that the Quran is the direct word of God. They believe that the angel Gabriel, or Jibra’eel, came to the Prophet Muhammad and revealed the word of God to him, which the latter disseminated amongst his followers. Muslims further believe that the word of God, the Quran, is revealed to be a source of guidance and direction for all humanity. The fact that they consider it the last revelation of God to mankind further stipulates that Muslims consider this to be the last guidance sent to man from God. This entails t hat they spend their lives trying to live according to the edicts of the Quran, and trying to bring their lives as close to the commands of the Quran as possible. The Muslims consider this to be a book from God for a multiple of reasons. One reason, as is put forward in the Quran itself, is that such a book, with its poetic and miraculous nature could never be produced by man. In the second Chapter, or Surah, of the Quran (the Cow, or Al-Baqarah), it is said â€Å"And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (if there are any) besides Allah, if your (doubts) are true† (verse 23). Furthermore, the Muslims believe that there have been miraculous claims in the Quran that are further testament to it being the word of God. These include various predictions or prophecies in the Quran that were later fulfilled. One such prophecy relates to the body of the Pharaoh (the Phara oh said to have oppressed the Jews); when relating the story of his death, God thus speaks to the Pharaoh in the Quran â€Å"This day shall We save thee in the body, that thou mayest be a sign to those who come after thee! but verily, many among mankind are heedless of Our Signs!† (10: 92). The mummified body of a Pharaoh in an Egyptian Museum in Cairo is said to have been that of the same Pharaoh, thus the Quran’s prophecy regarding his body being preserved has proven to have come true. Further, a few years after the Byzantines had been defeated by the Persians completely, a revelation of the Quran said â€Å"The Roman Empire has been defeated – In a land close by; but they, (even) after (this) defeat of theirs will soon be victorious – within a few years†¦Ã¢â‚¬  (60: 2-4). This seemed impossible as the Byzantines had incurred heavy losses and the Empire seemed to be at the brink of total annihilation, however, a few years after this revelation, t he Persians were, indeed, defeated by the Byzantines. Moreover, in Chapter 48 of the Quran, a prophesy is given regarding the taking of Mecca: â€Å"†¦ye shall enter the Sacred Mosque, if Allah wills, with minds secure, heads shaved, hair cut short, and without fear†¦Ã¢â‚¬  (27). Some time afterwards, Mecca was indeed conquered by Muhammad and his followers, and they did enter the Sacred Mosque, or Kaaba, in the same condition described herein. Also, there have been some statements in the Quran that have been recently proven to be scientifically accurate. For example, when a verse of the Quran says â€Å"By the Firmament which returns (in its round)† (86: 11) and â€Å"

Native Americans Assignment Example | Topics and Well Written Essays - 250 words

Native Americans - Assignment Example Albanese (36) explains that Native Americans have responded positively to other religions assimilating some foreign practices, integrating religions, or conversion to new religion. Any of the three actions demonstrated compatibility, in either principles or beliefs, between Native American religions and religions among immigrant groups, and therefore suggests possible religious effects on the immigrant groups. Commonalities within the native religions, that distinguished them from foreign religions is another aspect that establishes the traditional religions as a microcosm for other religious adaptations. Even in their interactions with other religions, the native religions have sustained their identity, with peyote religion as an example (Albanese 37), and this shows that immigrant groups would monitor religious interactions for sustainability of their respective religious identities. Identity aspect of commonalities within religion would influence religions to establish distinct values for sustainability among other religions. Existence of relationship with a supreme authority, which is common among the Native American religions and other religions such as Christianity (Albanese 23- 25), is another illustration of the native religions as a basis for understanding possible religious adaptations among immigrant groups. The groups’ changes in religion would therefore be limited to such relationships with supernatural beings. Existence of distinct practices and beliefs among the native religions and foreign religions, together with compatibility into systematic religious interactions for sustaining religious identity are therefore microcosm for understanding religious adaptations of immigrant

Electrochemical battery

Electrochemical battery HISTORY An early form of electrochemical battery called the Baghdad Battery may have been used in antiquity. However, the modern development of batteries started with the Voltaic pile, invented by the Italian physicist Alessandro Volta in 1800. In 1780 the Italian anatomist and physiologist Luigi Galvani noticed that dissected frogs legs would twitch when struck by a spark from a Leyden jar, an external source of electricity. In 1786 he noticed that twitching would occur during lightning storms. After many years Galvani learned how to produce twitching without using any external source of electricity. He started doing his experiments on frogs with metals but he replaced them with electrolyte and electrodes and named the system as voltaic cell. In 1800, Volta invented the battery by placing many voltaic cells in series, literally piling them one above the other. This Voltaic pile gave a greatly enhanced net emf for the combination. After voltaic cell, in 1836 Daniell cell came into existence. It provided more stable current and was also accepted by the industries. These wet cells were not portable as there liquid electrolyte used to spill. Therefore by the end of nineteenth century dry batteries came into existence in which the liquid electrolyte was replaced with dry paste making the dry batteries portable. Working of Batteries Electrochemical cell In this example the two half-cells are linked by a salt bridge separator that permits the transfer of ions, but not water molecules. A battery is a device that converts chemical energy directly to electrical energy. It consists of a number of voltaic cells; each voltaic cell consists of two half cells connected in series by a conductive electrolyte containing anions and cations. One half-cell includes electrolyte and the electrode to which anions (negatively-charged ions) migrate, i.e. the anode or negative electrode; the other half-cell includes electrolyte and the electrode to which cations (positively-charged ions) migrate, i.e. the cathode or positive electrode. In the redox reaction that powers the battery, reduction (addition of electrons) occurs to cations at the cathode, while oxidation (removal of electrons) occurs to anions at the anode. The electrodes do not touch each other but are electrically connected by the electrolyte, which can be either solid or liquid. Many cells use two half-cells with different electrolytes. In that case each half-cell is enclosed in a container, and a separator that is porou s to ions but not the bulk of the electrolytes prevents mixing. Each half cell has an electromotive force (or emf), determined by its ability to drive electric current from the interior to the exterior of the cell. The net emf of the cell is the difference between the emfs of its half-cells, as first recognized by Volta. Therefore, if the electrodes have emfs and, then the net emf is; in other words, the net emf is the difference between the reduction potentials of the half-reactions. The electrical driving force or across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. The terminal voltage of a cell that is neither charging nor discharging is called the open-circuit voltage and equals the emf of the cell. Because of internal resistance, the terminal voltage of a cell that is discharging is smaller in magnitude than the open-circuit voltage and the terminal voltage of a cell that is charging exceeds the open-circuit voltage. An ideal cell has negligible internal resistance, so it would maintain a constant terminal voltage of until exhausted, then dropping to zero. If such a cell maintained 1.5 volts and stored a charge of one Coulomb then on complete discharge it would perform 1.5 Joule of work. In actual cells, the internal resistance increases under discharge, and the open circuit voltage also decreases under discharge. If the voltage and resistance are plotted against time, the resulting graphs typically are a cur ve; the shape of the curve varies according to the chemistry and internal arrangement employed. As stated above, the voltage developed across a cells terminals depends on the energy release of the chemical reactions of its electrodes and electrolyte. Alkaline and carbon-zinc cells have different chemistries but approximately the same emf of 1.5 volts; likewise NiCd and NiMH cells have different chemistries, but approximately the same emf of 1.2 volts. On the other hand the high electrochemical potential changes in the reactions of lithium compounds give lithium cells emfs of 3 volts or more. Categories and types of batteries Main article: List of battery types Batteries are classified into two broad categories, each type with advantages and disadvantages. Primary batteries irreversibly (within limits of practicality) transform chemical energy to electrical energy. When the initial supply of reactants is exhausted, energy cannot be readily restored to the battery by electrical means. Secondary batteries can be recharged; that is, they can have their chemical reactions reversed by supplying electrical energy to the cell, restoring their original composition. Historically, some types of primary batteries used, for example, for telegraph circuits, were restored to operation by replacing the components of the battery consumed by the chemical reaction.[34] Secondary batteries are not indefinitely rechargeable due to dissipation of the active materials, loss of electrolyte and internal corrosion. Primary batteries Primary batteries can produce current immediately on assembly. Disposable batteries are intended to be used once and discarded. These are most commonly used in portable devices that have low current drain, are only used intermittently, or are used well away from an alternative power source, such as in alarm and communication circuits where other electric power is only intermittently available. Disposable primary cells cannot be reliably recharged, since the chemical reactions are not easily reversible and active materials may not return to their original forms. Battery manufacturers recommend against attempting to recharge primary cells. Common types of disposable batteries include zinc-carbon batteries and alkaline batteries. Generally, these have higher energy densities than rechargeable batteries, but disposable batteries do not fare well under high-drain applications with loads under 75 ohms (75 ÃŽ ©). Secondary batteries Main article: Rechargeable battery Secondary batteries must be charged before use; they are usually assembled with active materials in the discharged state. Rechargeable batteries or secondary cells can be recharged by applying electrical current, which reverses the chemical reactions that occur during its use. Devices to supply the appropriate current are called chargers or rechargers. The oldest form of rechargeable battery is the lead-acid battery. This battery is notable in that it contains a liquid in an unsealed container, requiring that the battery be kept upright and the area be well ventilated to ensure safe dispersal of the hydrogen gas produced by these batteries during overcharging. The lead-acid battery is also very heavy for the amount of electrical energy it can supply. Despite this, its low manufacturing cost and its high surge current levels make its use common where a large capacity (over approximately 10Ah) is required or where the weight and ease of handling are not concerns. A common form of the lead-acid battery is the modern car battery, which can generally deliver a peak current of 450 amperes. An improved type of liquid electrolyte battery is the sealed valve regulated lead acid (VRLA) battery, popular in the automotive industry as a replacement for the lead-acid wet cell. The VRLA battery uses an immobilized sulfuric acid electrolyte, reducing the chance of leakage and extending shelf life. VRLA batteries have the electrolyte immobilized, usually by one of two means: Gel batteries (or gel cell) contain a semi-solid electrolyte to prevent spillage. Absorbed Glass Mat (AGM) batteries absorb the electrolyte in a special fiberglass matting Other portable rechargeable batteries include several dry cell types, which are sealed units and are therefore useful in appliances such as mobile phones and laptop computers. Cells of this type (in order of increasing power density and cost) include nickel-cadmium (NiCd), nickel metal hydride (NiMH) and lithium-ion (Li-ion) cells. By far, Li-ion has the highest share of the dry cell rechargeable market. Meanwhile, NiMH has replaced NiCd in most applications due to its higher capacity, but NiCd remains in use in power tools, two-way radios, and medical equipment. Battery cell types There are many general types of electrochemical cells, according to chemical processes applied and design chosen. The variation includes galvanic cells, electrolytic cells, fuel cells, flow cells and voltaic piles. Wet cell A wet cell battery has a liquid electrolyte. Other names are flooded cell since the liquid covers all internal parts, or vented cell since gases produced during operation can escape to the air. Wet cells were a precursor to dry cells and are commonly used as a learning tool for electrochemistry. It is often built with common laboratory supplies, like beakers, for demonstrations of how electrochemical cells work. A particular type of wet cell known as a concentration cell is important in understanding corrosion. Wet cells may be primary cells (non-rechargeable) or secondary cells (rechargeable). Originally all practical primary batteries such as the Daniel cell were built as open-topped glass jar wet cells. Other primary wet cells are the Leclanche cell, Grove cell, Bunsen cell, Chromic acid cell, Clark cell and Weston cell. The Leclanche cell chemistry was adapted to the first dry cells. Wet cells are still used in automobile batteries and in industry for standby power for switchgear, telecommunication or large uninterruptible power supplys, but in many places batteries with gel cells have been used instead. These applications commonly use lead-acid or nickel-cadmium cells. Dry cell A dry cell has the electrolyte immobilized as a paste, with only enough moisture in the paste to allow current to flow. Compared to a wet cell, the battery can be operated in any random position, and will not spill its electrolyte if inverted. While a dry cells electrolyte is not truly completely free of moisture and must contain some moisture to function, when it was first developed it had the advantage of containing no sloshing liquid that might leak or drip out when inverted or handled roughly, making it highly suitable for small portable electric devices. By comparison, the first wet cells were typically fragile glass containers with lead rods hanging from the open top, and needed careful handling to avoid spillage. An inverted wet cell would leak, while a dry cell would not. Lead-acid batteries would not achieve the safety and portability of the dry cell, until the development of the gel battery. A common dry cell battery is the zinc-carbon battery, using a cell sometimes called the dry Leclanchà © cell, with a nominal voltage of 1.5 volts, the same nominal voltage as the alkaline battery (since both use the same zinc-manganese dioxide combination. The makeup of a standard dry cell is a zinc anode (negative pole), usually in the form of a cylindrical pot, with a carbon cathode (positive pole) in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste next to the zinc anode. The remaining space between the electrolyte and carbon cathode is taken up by a second paste consisting of ammonium chloride and manganese dioxide, the latter acting as a depolarizer. In some more modern types of so called high power batteries, the ammonium chloride has been replaced by zinc chloride. Battery cell performance A batterys characteristics may vary over load cycle, charge cycle and over life time due to many factors including internal chemistry, current drain and temperature. Extending battery life Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, because the chemical reactions in the batteries are slower. Such storage can extend the life of alkaline batteries by ~5%; while the charge of rechargeable batteries can be extended from a few days up to several months. In order to reach their maximum voltage, batteries must be returned to room temperature; discharging an alkaline battery at 250 mAh at 0 °C is only half as efficient as it is at 20 °C. As a result, alkaline battery manufacturers like Duracell do not recommend refrigerating or freezing batteries. Hazards 1.) Explosion A battery explosion is caused by the misuse or malfunction of a battery, such as attempting to recharge a primary (non-rechargeable) battery, or short circuiting a battery. With car batteries, explosions are most likely to occur when a short circuit generates very large currents. In addition, car batteries liberate hydrogen when they are overcharged (because of electrolysis of the water in the electrolyte). Normally the amount of overcharging is very small, as is the amount of explosive gas developed, and the gas dissipates quickly. However, when jumping a car battery, the high current can cause the rapid release of large volumes of hydrogen, which can be ignited by a nearby spark. When a battery is recharged at an excessive rate, an explosive gas mixture of hydrogen and oxygen may be produced faster than it can escape from within the walls of the battery, leading to pressure build-up and the possibility of the battery case bursting. In extreme cases, the battery acid may spray violently from the casing of the battery and cause injury. Overcharging—that is, attempting to charge a battery beyond its electrical capacity—can also lead to a battery explosion, leakage, or irreversible damage to the battery. It may also cause damage to the charger or device in which the overcharged battery is later used. Additionally, disposing of a battery in fire may cause an explosion as steam builds up within the sealed case of the battery. 2.) Leakage One style of disposable battery uses zinc can as both a reactant and as the container to hold the other reagents. If this kind of battery is run all the way down, or if it is recharged after running down too far, the reagents can emerge through the cardboard and plastic that forms the remainder of the container. The active chemicals can then corrode or otherwise destroy the equipment that they were inserted into. Many battery chemicals are corrosive or poisonous or both. If leakage occurs, either spontaneously or through accident, the chemicals released may be dangerous. 3.) Environmental concerns The widespread use of batteries has created many environmental concerns, such as toxic metal pollution. Battery manufacture consumes resources and often involves hazardous chemicals. Used batteries also contribute to electronic waste. Some areas now have battery recycling services available to recover some of the materials from used batteries. Batteries may be harmful or fatal if swallowed. Recycling or proper disposal prevents dangerous elements (such as lead, mercury, and cadmium) found in some types of batteries from entering the environment. In the United States, Americans purchase nearly three billion batteries annually, and about 179,000 tons of those end up in landfills across the country. In the United States, the Mercury-Containing and Rechargeable Battery Management Act of 1996 banned the sale of mercury-containing batteries (except small button cell batteries), enacted uniform labeling requirements for rechargeable batteries, and required that rechargeable batteries be easily removable. California and New York City prohibit the disposal of rechargeable batteries in solid waste, and along with Maine require recycling of cell phones. The rechargeable battery industry has nationwide recycling programs in the United States and Canada, with drop-off points at local retailers. Battery chemistry Older batteries were mostly based on rechargeable lead-acid or non-rechargeable alkaline chemistries, with nominal voltages in increments of 2.10 2.13 and 1.5Volts respectively, each representing one individual electrochemical cell. New special battery chemistries have strained older naming conventions. Rechargeable NiCd (Nickel Cadmium) and NiMH (Nickel Metal Hydride) typically output 1.25V per cell. Some devices may not operate properly with these cells, given the 16% reduction in voltage, but most modern ones handle them well. Conversely, lithium-ion rechargeable batteries output 3.7V per cell, 23% higher than a pair of alkaline cells (3V), which they are often designed to replace. Non-rechargeable lithium-chemistry batteries, which provide exceptionally high energy density, produce about 1.5V per cell and are thus similar to alkaline batteries. Many new battery sizes refer to both the batteries size and chemistry, while older names do not. For a more complete list see battery types. This summary is only for types relating to battery sizes. Homemade cells Almost any liquid or moist object that has enough ions to be electrically conductive can serve as the electrolyte for a cell. As a novelty or science demonstration, it is possible to insert two electrodes made of different metals into a lemon, potato, etc. and generate small amounts of electricity. Two-potato clocks are also widely available in hobby and toy stores; they consist of a pair of cells, each consisting of a potato (lemon, et cetera) with two electrodes inserted into it, wired in series to form a battery with enough voltage to power a digital clock. Homemade cells of this kind are of no real practical use, because they produce far less current—and cost far more per unit of energy generated—than commercial cells, due to the need for frequent replacement of the fruit or vegetable. In addition, one can make a voltaic pile from two coins and a piece of paper towel dipped in salt water. Such a pile would make very little voltage itself, but when many of them are s tacked together in series, they can replace normal batteries for a short amount of time. Sony has developed a biologically friendly battery that generates electricity from sugar in a way that is similar to the processes observed in living organisms. The battery generates electricity through the use of enzymes that break down carbohydrates, which are essentially sugar. Lead acid cells can easily be manufactured at home, but a tedious charge/discharge cycle is needed to form the plates. This is a process whereby lead sulfate forms on the plates, and during charge is converted to lead dioxide (positive plate) and pure lead (negative plate). Repeating this process results in a microscopically rough surface, with far greater surface area being exposed. This increases the current the cell can deliver. Daniell cells are also easy to make at home. Aluminum-air batteries can also be produced with high purity aluminum. Aluminum foil batteries will produce some electricity, but they are not very efficient, in part because a significant amount of hydrogen gas is produced.

Stereoptyping, Labeling, Pre-judging Essay -- Personal Narrative Racis

Stereoptyping, Labeling, Pre-judging One day as I was shopping in Patterson’s at the mall here in Bemidji I noticed somethin that I have seen quite a lot of as I have been living in this town of racial diversity. I seemed to notice when I walked in the store with my mom we got the expected "Hello, can I help you find something?". We said "No, we are just looking." and went on our way through the store. A couple of minutes later some Natives came in the store and the guy who was working acted much different. He kind of looked at them with a disgusted look and followed them about the store without really saying anything. If he did it was something like "What size are you looking for?", no hellos or any chance of using the word help. I watched how he kind of looked at them with a sick grin on his face resembling a smirk of disgust. My mom also saw this same thing happen a couple of days earlier but didn’t say anything until we left the store. I have never really liked this guy working there because I have seen him do this almost every time I am in the store and that type of thi...

Women In Business Essay

Unassuming nature (humility) M – Motivator I- Interpersonal skills S – Sense of purpose E – Empathic N – Notable – Innovative N – Novice S – Self-confidence Spokesman N – Never giving up E- Efficacious In the business world there are a lot of obstacles women have to face to climb the career ladder. Helen Keller once said, â€Å"Never bend your head. Always hold it high. Look the world right in the eye. † Women should take this message and run with it. It's not the people around us but ourselves which holds us back from what we want to accomplish.Self-confidence is the master key that unlocks the door in succeeding in today's business world. Confidence in one's self assists in elevating our position. Once a woman is confident, she has pride in her work and a little hard work comes easy. Singer Marsha Evans once remarked, â€Å"You can have unbelievable intelligence, you can have connections, you can have opportunities fal l out of the sky. But in the end hard work is the true, enduring characteristic of successful people. † Women, today we need not to be afraid of hard work. Working long hours and sacrificing our spare time is what it takes to build a business.Sometimes aging on an extra task can be beneficial to building the career we actually seek. We are classified as the ‘weaker vessels', but if we endure the hard work, it only makes us stronger and climbing the career ladder would be easy. As aforementioned in the acronym, the attribute listed for ‘B' in the word BUSINESS was bravery. Being a woman in a corporate world you would be timid by the male gender. You have to constantly push yourself out of your comfort zone to move forward. This means you have to take risks and accept when things go dismay. No matter the challenge or situation be brave.You will survive and turn things around. I am a young woman striving to succeed. Ambition is embedded. I don't settle for second best . â€Å"Reach for the stars†, but in reality I want to have it in the palm of my hands. My vision, dreams and aspirations will be a reality. The words of Anita Rowdier, â€Å"To succeed you have to believe in something with such a passion that it becomes a reality', and know I have passion within. For no matter what it is once I'm involved I will be passionate and committed. I stumbled upon a poem and the words of it really depicts who am and the attributes posses.Heart of a Woman in Business by Sherry Rough is an inspirational poem for women for all walks of life. A woman in business is like no other Multi-brilliant at work, and often too, a mother. Guided by vision to make a difference in this world, Reporting for service, with her hair even curled. Ready to go, whenever the need She knows in her heart, there's a calling to feed. To do right, to speak up, determined to succeed A role model that plants the possibility seed. Knows who she is, right down to the core Her essen ce, her passion-?shine all the more! She's in charge with a handle on it all.At the office, at home, or at the mall. Even in the depth of all she may know Realizes there's still plenty room to grow. So energetic, creative and fun . Early rise, there's much to be done!

It will allow me to build on the skills and traits that I already own and develop new ones that will take me on the road to success full speed.Women rarely hold highly influential leadership positions. I believe that women are just as capable of being successful leaders as men with the same abilities. If more women are allowed and encouraged to become leaders, it would create a wavelet effect throughout society. There is an imbalance in the business world between men and women leaders. It is very critical that women hold leadership position. Within the work environment there will be new perspectives and outlook on different situations. We have accepted the mental abilities that men and women are equal. Marie C.Wilson in Closing the Leadership Gap: Add Women Change Everything said, â€Å"When look at issues face, and when I think of the need, I am as convinced as I have ever been that our future depend s on the leadership of women – not to replace men but to transform our options alongside them. † These words that came forth is truly a divine statement. Women holding leadership positions isn't undermining men in influential positions but wanting to work hand in hand with them. You receive views from each person and ideas can be formulated and bought forth. It shouldn't be about male vs.. Male but about how we can all benefit.Right now too much power is placed within the grasp of men and the masculine perspective. A survey from Right Management Consultants shows that the skill that companies most often seek in managers is the ability to motivate and engage others. These characteristics are displayed more from women. Ultimately, if women are in leadership positions with their male counterpart, the feminine qualities such as intuitive, compassionate and emotional nature will bloom. â€Å"The gateway to our intuitive wisdom and our connection to the rater landscape of hu manity is emotions,† quote Tabby Fiddle.
