Extraordinary Educators Teacher Appreciation Stories

Extraordinary Educators Teacher Appreciation Stories Read about teachers who go the extra mile for their students and colleagues every day. Back in May, we asked teachers to enter our Teacher Appreciation giveaway by nominating a fellow teacher who inspired them as an educator. We received so many amazing stories from all over the country - spouses who worked together and drew inspiration from the other, daughters who became teachers to emulate their mothers, and newer teachers expressing gratitude for their mentors, just to name a few. We’re going to be sharing some of our favorite entries throughout the summer, beginning with the two below! Our first story is from our Grand Prize Winner Kimberly Cobb, a special education teacher working with fifth- and sixth-graders in an economically disadvantaged district in Maine. She nominated Jessica Hartford, her fellow fifth-grade teacher, saying: “Jess teaches her students in innovative ways, she uses hands-on activities to help her students learn. She takes them fly fishing every year, takes them outside to teach them about the kinds of trees and their attributes, and does many of her science lessons with hands-on activities. She takes new teachers on her grade level under her wing and guides them throughout the year to help them learn best ways to teach difficult curriculum, problem-solving for classroom behavior management, and other things to help them have a smooth year. She is a leader among teachers. She is always advocating for the environment with her students to give them the information they need to understand human impact on the environment. Most importantly, Jess always advocates for her students and what is best for them first and foremost.” It’s amazing to see what committed teachers can do, even with limited resources at their disposal. Congratulations to Kim and Jessica, who each received an Amazon gift card and 1-year membership to TeacherVision. Our second entry comes from Anne Faulks, a seventh-grade language arts teacher in Tennessee who calls her profession “a challenging joy.” She nominated her school’s band teacher, Angela Sanders. “Mrs. Sanders is a phenomenal teacher. She takes students from very limited music and band knowledge to sounding like professional musicians. Her patience is remarkable! One year, her jazz band students made a CD. I had my brother, someone who knows and likes jazz, to listen to the CD. He asked about the band. He was surprised to know that the band was composed of only middle school musicians. For our school Veterans Day program, we had the Navy band perform. The Navy band moved from our area and were not able to perform for our recognition program. Mrs. Sanders stepped in, trained students by teaching them the service anthems, and had them play during all three school lunch periods. Her students performed as well as the Navy Band. They also played other pieces of music that was of interest to the veterans as well as the students. Visiting veteran guests, myself included, marveled at their talent and skill at playing the various service anthems. Band students were dressed in patriotic tee shirts that matched the theme of the program. Some of the visiting guests stayed after the lunch periods and the program ended just to continue to enjoy the sounds of the Appling School Band. Mrs. Sanders also participates as a member of the Bartlett Community Band. She encourages her students to audition. Many have joined the band and perform with her. Her face expresses pride as she performs along with her current and former students. She delights in her students’ successes. Many have gone on to receive scholarships to college and to become music/band teachers themselves. I cannot say enough good things about Mrs. Sanders. She is just a phenomenal teacher who loves and enjoys what she does with all of her being!” By sharing Mrs. Sanders’ exceptional work as a music teacher, Anne demonstrated perfectly why arts education is so crucial for many students.

Optimal capital structure debt and equity - Free Essay Example

Literature Review The capital structure of the firm is made of two things, one is the level of debt and the other is the proportion of equity. The management of the firm has to decide an appropriate mix of both the funding sources for the smooth running of the firm and the maximization of the shareholders wealth. Traditional view was that to increase gearing level to get weighted average cost of capital (WACC) low which will consequently give a higher present value of future cash flows and enhance shareholders wealth. However the higher level of debt will require a higher payment of interests before dividends which in turn leads the firm to become financially distressed and in extreme circumstances to be liquidised. Therefore, getting an optimal capital structure is essential. In this study I will discuss the two theories, optimal capital structure theory and the pecking order theory with the help of literature. Literature Review of Optimal Capital Structure Theory Franco Modigliani and Merton Miller (1958) developed a theory for optimal capital structure. At first they assumed that there is a perfect capital market which means that there are no income taxes and transaction costs. If the market is ideal then the firms capital structure is inappropriate to its value as the investors are prudent, the required return of equity is directly proportional to increase in gearing. There is thus a linear association between cost of equity and gearing. The boost in cost of equity precisely offsets the benefits of the cheaper debt finance and therefore the WAAC remains unaffected. A number of practical criticisms were made at the assumptions of perfect market specifically at the supposition of no taxes which seemed unrealistic because the debt interest is tax deductible the effect of tax could not be neglected. However when corporation income taxes and transaction costs came into play Miller and Modigliani(1963) changed their view of having a perfect market and rephrased their theory saying that because debt interest is tax deductible the optimal capital structure can be complete debt finance as substituting debt instead of equity generates extra tax savings which can not be achieved otherwise. Firms can then pass on this extra saving to share holders and other investors in the form of higher returns. Arnold. G (2004) further explains this modified view as a firm financed with 99% of debt and 1% of equity serves its shareholders better then one funded by 50% debt and 50% equity. This in turn means that debt finance is cheaper then equity and using as much debt as possible in a firms capital structure will make the performance and outcome outstanding in terms of returns to its investors. This raised a further question that if the debt reduces the tax payments and results in the higher dividends to share holders then does this mean that the firms financed largely by equity are paying unnecessary corporation tax on the share hol ders funds? Miller (1977) discussed this problem as by increasing the debt finance in capital structure of the company we can save money on tax payouts but this will not change the value of the entity because the money saved by increasing the debt finance is paid back to the share holders in the form of dividends. In other words if the interest payments of debt is greater than the equity returns then it removes the advantage of debt finance. (Anne P. Villamil) The problem with Miller and Modiglianis theories is that if the company is financed by 99% debt it will put the company in the utter most degree of risk because debt is riskier than equity as well as cheaper. What is meant by risk here is that lenders will want their return before company can do anything else with its earnings and if company have to pay large amounts of its revenue towards the lenders then other obligations such as payments to suppliers, dividends, wages and salaries and other business expenses will not be met by the company. This can also result in poor rating by agencies and will stop investors to invest in the company in future and there will be no other way then to liquidise the company. Pecking Order Theory This theory is managerial type in which Myer (1984, p581) gives the idea that there is no such thing as optimal capital structure instead he argues that firms should raise finance in three different ways in order to save costs. Firstly they should generate funds internally secondly the debt finance should be used and thirdly there should some new share issues as well if needed. The ranking of fund raising in this particular way is entirely based upon the issue costs of the three different types. Because internally generated funds have the lowest issue costs then issuing debt has moderate issue costs and issue new equity has the highest costs. Therefore firms when ever they need funds for what ever reason should first generate funds internally and then move on to the next category if they need to. The pecking order theory is best explained by perspective of asymmetric information and the existence of transaction costs. Asymmetric or uneven information costs exist when firms produ ce funding for them internally to bring an investments net present value (NPV) to be positive. The outside investors, when the market price of the equity is greater than the actual value can under or over estimate the price of equity because usually they have very limited information about the company as compared to the managers and this gives chance to the managers to issue securities at a higher price (Myers and Majluf 1984). Some elegant investors are aware of the incentives behind the issue of new equity when the market overvalues the existing equity therefore they will adjust the price accordingly and as a result of this the new securities will be under priced in the market. The impact of under priced new equity issue will be a loss to existing share holders because new investors detain more of the NPV of the new project. The managers acting in the favour of existing share holder in such circumstances will reject the project even if the NPV is positive. This under investment ca n be avoided by financing the new project internally. (Mayer and Majluf 1984). The pecking order theory can also be explained by way of transaction costs. The costs linked with external fund raising are the key to select the source of finance. The sources can be ranked in order of the transaction costs associated with them as explained in the start of the pecking order theory section. There is another reason for the managers to give internal financing preference over external financing that is the managers or owner do not want to lose control over the entity by giving chance to the new share holders to enter in the company and exercise control (Holmes and Kent, 1991; Hamilton and Fox, 1998) therefore managers will attempt to finance their activities as much as possible with internally generated funds. However if there are no sufficient funds available to support the activities then the next option manager will choose for financing will be the one which gives the investor no or ve ry less control over the entity such as short term and long term debt and the final choice if there is no other way to raise finance will be issue of new equity. The problem with the pecking order theory is that it presses the point of giving preference to internal funds. If this is the case then the firm would have gearing ratio equal to zero. However, for being able to have enough internally generated funds and to cope with growth or to finance the activities the firm should be well established and mature. In reality this is not possible for most of the growing firms which do not have that level of internal funds therefore they have no other choice but to rely on debt finance which means the gearing ratio tends to move away from zero. Conclusion There is no any optimum capital structure which a firm can adopt and start running its businesses. A firm can get the point of gearing where it can maximize the shareholders wealth but finding that point is the problem in the real world. The point of optimum level of gearing is different for different type of industries like some of them have small level of borrowings, References Modigliani F. and Miller M., 1958.

Several factors can influence our gender identity. As a child (nurture) can help to shape, ones gender identity. One’s father and mother can see their child as male or female, meaning they see female as having feminine traits and a male as having masculine traits. For example, I was born female and this is the main factor in the evolution of my personal gender identity. My mother and father tried to dress me in clothes for a girl, while trying to teach me how to sit like a lady, and to show characteristics that are considered to fit my gender (female). Society defines a person’s gender by what they see; meaning the outward appearance of the individual is how they determine a person’s gender. Some people base their gender identity on social norms. I would not say that my gender identity has been easily influenced by society or culture. I may relate to the feminine role and that may be a reason why I consider myself a female.

American History And Its Impact On America - 1107 Words

American History American History and its people are extremely important to the health and progression of their nation. So may played a critical part in shaping this nation into what it is today. Even though many would love just to focus on the crisis and bad decisions that some have made. Our country is considered the land of the free, land of opportunity, land of dreams coming true. We can’t let bad choices by a few select cloud who we are and celebrate the great achievements we have made together as a nation. To do so would be to make a mockery out of the lives of those who worked so hard to shape this nation into one of the greatest nations on the earth. Most of these people acted from a place of strong faith and beliefs. They forged on against adversity and hostility because of this hope in God and in freedom. Thomas Jefferson was a man who helped establish this country on faith. He was the initial author of the Declaration of Independence and key to affirming freedom and rights for Americans. Jefferson introduced the statue of religious freedom. This is still having an impact on our society today and has helped solidify Christians’ faith across this country.

What is Cryptography Free Essays

Technology has developed throughout the years, which has been shown by changes in different aspects of how people live their daily lives. One example could be the means of transportation which started from horses during early times to carriages, invention of automobiles, aircrafts, submarines and many more which we use at present. Through centuries, sending of messages has also evolved from messenger mail to electronic mail via the World Wide Web. We will write a custom essay sample on What is Cryptography? or any similar topic only for you Order Now Along with these are rising security threats to senders and receivers of those messages who fear that their mail would be opened by someone else. It is and has been the same problem ever since. How can these security threats and privacy invasions be avoided then? The main topic of this research is the importance of a science that helps everyone. It could be in terms of technology to the benefit of computer enthusiasts and industrialists, or simply for protection of the privacy of each citizen. The following pages would give the readers a brief introduction of the subject at hand, Cryptography. Along with its definition, history, forms and uses, readers would also be able to learn how important this science is and why each person should use it in their daily communication. According to the Merriam-Webster online dictionary, Cryptography is the enciphering and deciphering of messages in secret code or cipher, the computerized encoding and decoding of information. It is also known as secret writing. Derived from the Greek words kryptos, which means hidden and the grafo, meaning write, is the transformation of data into a secure message, so that unintended recepients would not be able to understand or use them. (Wikibooks, Inc. , 2007). Cryptography is used to hide information by means of encryption, therefore making data unreadable to those who don’t have the secret key that can decipher or decrypt the message into an understandable one. Encryption is done when information is transformed into something which others might see as useless. This is called ciphertext. The act of transforming the said information into an understandable format with the use of a cipher or secret key is called decryption. (Wikibooks, 2007) The use of cryptography is seen today through its many uses. These include the security of ATM cards, electronic commerce and computer passwords. These are used for access control and confidentiality of secure information. (Cryptography, 2007) Such techniques like microdots and combining words with images are used by cryptographers to hide information from unintended recepients. (Pawliw, 2006) The earliest known use of cryptography is Classical Cryptography. It shows that it has been thousands of years since cryptography was first done. History has stated that the first proof of the use of cryptography dates back to 2000 BC. It has been related with the Egyptians’ practice of hieroglyphics which consisted of complicated pictograms seen carved into monuments of Ancient Egypt. These pictograms were hard to interpret and only a chosen few knew what their real meanings were. Some time within 500 and 600 BC, Hebrew scholars made use of simple substitution ciphers like the Atbash Cipher in order to solve these encrypted messages. According to Wikibooks, the first known use of a modern cipher was by Julius Caesar (100 BC to 44 BC): â€Å"†¦who did not trust his messengers when communicating with his governors and officers. For this reason, he created a system in which each character in his messages was replaced by a character three positions ahead of it in the Roman alphabet. † (Wikibooks, 2007) By the time of World War II, there has become a great use of mechanical and electromechanical cryptographic cipher machines, but the usage of these was very impractical. During this time, there were various developments in both mathematical and practical cryptography. When the period of modern cryptography began, Claude Shannon, father of mathematical cryptography, published the paper Communication Theory of Secrecy Systems in the Bell System Technical Journal in 1949. Shortly after that, along with Warren Weaver, he published the book Mathematical Theory of Communication as well. Because of those publications, a solid theoretical basis for cryptography and for cryptanalysis was established, which made cryptography known only by secret government communications organizations such as the NSA. It was only in 1969 that the public again saw developments in the field of cryptography: â€Å"First was the DES (Data Encryption Standard) submitted by IBM†¦ in an effort to develop secure electronic communication facilities for businesses such as banks and other large financial organizations†¦ it was adopted and published as a FIPS Publication (Federal Information Processing Standard) in 1977†¦has been made effectively obsolete by the adoption in 2001 of the Advanced Encryption Standard†¦DES was the first publicly accessible cypher algorithm to be ‘blessed’ by a national crypto agency such as NSA. The release of its design details by NBS stimulated an explosion of public and academic interest in cryptography. † (Wikibooks, 2006) Here are the important terms related to Cryptography in detail; Encryption is the act of hiding information using cryptography. Processed information in this manner is said to be encrypted. Decryption is the process of translating encrypted information. The Key is like a password used to encrypt and decrypt information. A transmission channel used to transmit information in secrecy is called a Secure Line, while a Public Line is the opposite. An example of which are public pay phones and the Internet. (Wooledge , 2000) There are several types of Cryptography being used today. In order to further explain the types of Cryptography, Wooledge compared the Key to a key to a door. First among these is the Symmetric Cipher, which can sometimes be called a symmetric key. Most of the time, it is used for simple types of cryptography because a same key is used to encrypt and decrypt the secret message. â€Å"Everybody who should have access to the room is given a copy of the key†¦put new information in, take old information out†¦if you send somebody a copy of the key by way of the Post Office, somebody working at the Post Office could intercept this key†¦allow them to access this same locked room, and do the same things with it†¦letting them read everything you locked up with that key, even letting them modify it. â€Å"(Wooledge , 2000) The Public Key Cryptography is more complex because in this type of cryptography there are two keys used and together, they are called a key pair. The key used to encrypt is called the public key, which can be given to anyone in order to send information to the owner of the private key, which will be used to decrypt information sent to him. The most common example of this is the use of electronic mail over the internet, also known as email. The public key is an email address which one gives out to his friends. This allows them to send information to the holder of the secret key, the owner of the email address, the only one who has the password to open and translate the information sent to him or her. (Wooledge , 2000) A One Time Pad is used to send high security messages such as national secrets and is considered the only perfect encryption in the world. In this type of encryption, both the sender and receiver has a copy of the pad to be used as a symmetric key to hide and unhide a message sent over a secure line and destroys them after it has been used. A good example of this is the one seen in Mission Impossible movies, wherein Ethan Hunt receives messages that self-destruct. (Wooledge , 2000) For the sake of totality, it would be best to include Steganography, the science of hiding information from people who would spy on a person. This type of encryption is designed not to let spies know that there is indeed a something hidden in a certain message. It is very effective, but only used occasionally. (Wooledge , 2000) Along with the internet, there is a large growth in the variety of forms of electronic communications, making its security very important. There are a number of enumerated uses for Cryptography such as protection of e-mail messages, credit card information, corporate and other important information. (Jupiter Media Corporation, 2004) After a brief background on Cryptography, readers would come to know why it is important to use them in their daily activities. The following are common concerns, goals or objectives that answer the above stated question. Message Confidentiality; Encrypted messages would only be understood by intended recepients of a certain message. If a sender would want to hide certain information from the public or from someone in particular, it would be best that cryptography is used. In that manner, only the receiver would have the key to translate the message into a useful and understandable one. Message Integrity; If an encrypted message is intercepted and changed during the sending process, it would easily be known by the receiver, which secures its integrity. Sender Authentication; It would be possible to make sure of the identities of both sender and recepient of the message. With cryptography, the recipient would be able to verify the true identity of the sender, along with the origin and destination of the message. Sender Non-Repudiation; This would prevent a sender from denying an intention to send and that he or she is the true sender of the said message. (Wikibooks, 2007) Though these cryptographic procedures are effective enough to achieve the goals, and concerns mentioned, it is still important for receivers and specially senders to practice caution such as creating a password with a very strong integrity, logging off private systems when they are not being used by the owner and keeping all private information to oneself.
