Upon this, a decision can be made whichever is important or urgent, and the matrix describes it into four categories, 1. Important and Urgent: There are two different types of urgent and important activities: ones that you could not have expected and others that you have left until the last minute. 2. Important but Not Urgent: These are the activities that support you to achieve your personal and professional goals for the long run and complete important work. 3. Not Important but Urgent: Urgent but not important tasks are things that prevent you from accomplishing your goals always try to reschedule or delegate them. 4. Not Important and Not Urgent: These activities are just a disruption, avoid them if possible. An external customer is someone who consumes your businesss products but is not part of your company. For example, an external customer is an individual who enters your store and buys merchandise or service. An internal customer is any member of your company who trusts on support from another to their job responsibilities, for example; sales representative who needs help from a customer service representative to complete an order. Another example for an internal customer; a customer calls on the call center to ask about his credit balance, the customer service agent calls the credit department to assist him to pass on the information to the end customer. And lastly, we have end users customer, business to business; which is a business that emphasis on marketing and selling products and services to other companies; for example in our direct English institution, we have other institutions that request to purchase our particular education course. Dealing with different customers the org anization must priorities for each, which mainly depends on its importance and its urgency for each situation and condition. 2.2 Effective communication is important to the company and it can be improved in many ways. In truth, communication act as a role in product development and customer relations also employee management and almost every aspect of a business operations process. Employees are a key audience because they often serve as the conduit to other audiences. If employees are knowledgeable, communications with other communities are likely to be strong as well. Effective structural communication will create a strong communication and the teamwork for employees to achieve company goals. There are mainly three types of communication, Verbal Communication which can be through a telephone or internet Skype, which is only through a voice channel, and Nonverbal Communication like emails, fax, SMS, test and lastly we have, Visual Communication which is mainly faced to face or meetings. Each has its own advantages and disadvantage for example; Verbal Communication you can communicate with a large number of cu stomers in short time, on the other hand, customer won’t be able to fully understand everything as the visual communication, and for Nonverbal Communication for example; customer has a reminder and a proof of the text which is reliable, on the other hand, some messages might be sent incorrectly and cause a large damage, Visual Communication is what customers prefer as so that they can express their emotions in better way, the disadvantage that this process takes lots of time to deal with each customer. 2.3 Effective service delivery, There are several overall points to think about when managing and planning the delivery of your services and products to be measured. There are also some particular aspects and methods that you may find helpful if you have limited time or resources. Within the framework of planning the business some aspects should be considered in order to improve the quality and the trust relationship with the community: Delivering service on time Time is limited. You cannot buy more time, but there are several things you can do to manage your time more efficiently. Plans rarely show up to be accomplished in the best way, and even the finest managers have to deal with unpredictable matters like suppliers not delivering on time, one of the employee members getting ill or trains are being delayed, equipment breaks, etc. Nevertheless, if you plan sufficiently you are more likely to deliver on time. When business starts deliver on time the business will start to be trusted and dependable, and this will attract lots of customers due to its timely delivery quality. Delivery service on a budget Planning a strategy based on a budget will enable you to identify the resources needed accurately before you start a project. Try to mark the things that may cost additional money. You should also make sure you are not forgetting anything that could end up costing you additional cost. Some practical preparation tools can be used to assist you to approximate how much resources will be needed at each stage of the process and how much will it cost and how long will it take. By then the business will start to reduce cost and be more efficient and effective in dealing the on a budget. Dealing with difficult customers First of all the one who deals with the customer needs to adjust his mindset once he/she is aware that the client is unhappy then the first priority is to have a customer service mindset. Secondly listen actively which is the most important phase of the whole dealing process is listening actively to what your client or customer is saying. Repeat the customers concerns to make sure that addressing the right issue, ask questions to make sure that youve identified the problem correctly. These matters should be considered when dealing with difficult customers, and it helps to solve future problems. Handling and resolving complaints Be Empathic and Apologize for example; I understand why youre upset. I would be too. Im very sorry that we didnt get the samples to you on time, especially since its caused these problems. And then to find or suggest the solution to his problem, if the suggested solution didn’t please the customer try to hear his perspective suggestion for the solution. Once you have both decided on a solution, you need to take action straight away. Explain every process to fix the problem to your customer Take Action and Follow-up to show your customer that you care. And lastly, use the Feedback from the complaints to decrease the risk of the condition happening again. References BIBLIOGRAPHY Eisenhower. (August 19, 1954). Eisenhowers Urgent/Important Principle.

Eclecticism: The Melting Pot of Education Essay -- Eclectic Teaching

Eclecticism: The Melting Pot of Education "Plasticene and self-expression will not solve the problems of education. Nor will technology and vocational guidance; nor the classics and the Hundred Best Books" (Aldous Huxley, English novelist, essayist, critic). If this is true, what will solve the problems of education? Hundreds have tried to answer that question and yet have said the same things over and over. A pure philosophy has never solved the problem of what to do about the education of the masses or the education of the individuahls, and because of that fact, I have not chosen any specific philosophy. I can only be described as eclectic, for I have taken different pieces from each of the five major philosophies and blended them into a personalized viewpoint. By drawing from the views of the great minds from the past, I have pieced together a way to describe what was already there: my point of view. Although I am eclectic, I have very strong opinions about what should be taught, and that is where I gather from the Essentialists. One of the basic beliefs of the Essentialists is that every child should, upon graduation, possess a basic body of knowledge. Included in this body of knowledge are such things as writing, reading, measurement, and computing. I agree that the child should have a basic body of knowledge, but I do not concur that it should be merely enormous rather than practical. In addition, I agree with the Essentialist beliefs that the program should be academically rigorous; that the teacher should model the correct behavior and instill such things as respect for authority, perseverance, dependability, dutifulness, consideration for others, and practicality. Traditional values and morals should be upheld ... ...hese various viewpoints has not influenced me to join a particular one, on the contrary they have strengthened my belief that no one person is right and only in a vast collection of cooperating educators and thinkers will the best environment for learning be achieved.

Stop Smoking :: essays research papers

Behavior Change Contract Paper   Ã‚  Ã‚  Ã‚  Ã‚  When the class was first told about the contract, I thought to myself that this can really help me stop smoking if I stick with it. I smoke about a pack a day, which is 20 cigarettes. I wanted to gradually decrease the amount of cigarettes I smoke every week for 7 weeks until I stopped smoking. Unfortunately this didn’t work and I was smoking the same amount I started with after the first week of the contract. There were three sets of factors that realy influenced me to continue to smoke.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  The first factor is the reinforcing factor, smoking is a very social and there are so many people that do it. There are always groups of people smoking anywhere, anytime. School is where I smoke the most cigarettes because I know a lot of people that smoke and whenever I see someone I know smoking I will join them and have a cigarette.   Ã‚  Ã‚  Ã‚  Ã‚  Next is the predisposing factor, this includes everything that is in my head already. Examples of this would be how I am mentally addicted to cigarettes and it feels like I will never be able to stop. This factor in my opinion has the biggest influence on me smoking.   Ã‚  Ã‚  Ã‚  Ã‚  The last factor is the enabling factor; today cigarettes are so easy to get, even for minors. Many of the stores wont even check IDs; they just sell them to whomever. Another enabling factor is that I make money, and can afford to buy the cigarettes at whatever price they are.   Ã‚  Ã‚  Ã‚  Ã‚  As you see these three factors had a lot to do with the reason why I couldn’t stop smoking cigarettes. I also think that another reason why I couldn’t stop was because of the whole reward system.

Hamptonshire Express Case Essay

1. a. The simulation indicates that 584 is the optimum stocking quantity. Daily profit at this stocking quantity is $331.4346. b. Using the newsvendor model, Cu = 1 – 0.2 = 0.8 and Co = .2. Cu /(Cu + Co) = .8. Using the spreadsheet, we found Q* = NORM.INV(.8,500,100) = 584.16. The simulation and newsvendor model give the same optimal stocking quantity. 2. a. According to the simulation spreadsheet, 4 hours of investment in creation maximizes daily profit at $371.33. b. Sheen would choose an effort level where the marginal benefit gained by the effort is equal to her marginal cost of expending the effort. To calculate the effort level, h, we equalize marginal cost and marginal benefit. Here (.8 * 50) / (2√h) = 10. Solving gives h = 4, or the same as the simulation. c. The optimal profit derived in this scenario is $371.33 per day, which is a $40 increase from the profit derived in problem #1, of $331.43. 3. a. Using the spreadsheet, Ralph’s optimal stocking quantity to maximize his profit is 516. b. The optimal stocking quantity differs from problem #2 because Ralph is incurring the cost of overstocking, which changes the critical ratio from .8 in problem #2 to .2. Because of the critical ratio change, Anna’s profit decreases as Ralph’s increases. This is consistent with the Newsvendor Model, which gives Cu=.2, Co=.8, for a critical ratio of .2. Using the formula in the spreadsheet, Q*=NORM.INV(.2,600,100)=515.837, gives the optimal stocking quantity of 516. c. Assuming that we only use whole numbers for her amount of time, Anna’s optimal effort is 2 hours with a profit of $261.93, a decrease from problem #2 of 4 hours. This is because Anna is now sharing her profit. d. If you decrease the transfer price, Anna’s effort level also decreases, and Ralph will increase his stocking quantity, adding to his profit. Anna’s effort level decreases because her profit decreases when Ralph buys the newspapers for less than $0.80. When the transfer price increases, the opposite occurs; Anna’s effort level increases and there is a decrease in Ralph’s stocking quantity and profit. 4. a. The optimal stocking quantity is 409 according to the spreadsheet in the simulation, which is a decrease from 516 in problem #3 because in the event that the Express stocks out, Ralph still makes a profit from 40% of  customers who will buy the Private. Therefore, because he makes more profit off of the Private, his risk decreases because of cost of understocking of the Express. b. For problems #1 and #2 there were no profitable alternatives to understocking, whereas in problem #3, Ralph has a profitable alternative for understocking since 40% of customers will buy the Private. The different critical ratios from each problem produce a different optimal stocking quantity. c. This decreases his optimal stocking quantity because Ralph is allocating $0.03 to the cost of each newspaper, making his cost of understocking now 1-.83-40%*.4=.01. Co=.83 Critical ratio 0.01/.83= 0.012 According to the data, the optimal stocking quantity is Q*=NORMINV(.012,500,100). 5. a. A lower buy-back price means a lower stocking quantity, because it affects the cost of overstocking. Ralph wants to stock a lower quantity in order to lower his risk of overstocking. The optimal buy-back price is $0.75, which gives a stocking quantity of 659 and channel profits of $369.80. b. The optimal transfer price is $0.99, giving a buy-back price of $0.988, and channel profits of $372.62. However, this is an unrealistic scenario because Ralph’s profits are negative at -$24 and Anna is making almost the full $1 price on each sale. The channel profit is very close to the $371.33 profit from problem #2. This is because the transfer price is almost the same as the selling price to customers of $1, eliminating Anna’s cost of under or overstocking. c. If Ralph had to pay a franchise fee, he would no longer have an incentive to understock. Anna’s effort would remain the same because the marginal benefit of her effort would not change given the additional fixed profit from Ralph’s fee.

Bloody Chamber Commentary Essays

Bloody Chamber Commentary Essays Bloody Chamber Commentary Essay Bloody Chamber Commentary Essay Essay Topic: Jaws There Will Be Blood It is late evening, the child runs out onto the moonlit green, searching for something in the lean grass, she had only the light of the moon to guide her as she gazes into the ground in melancholy. She swore she had it on her earlier, she swore to look after it, she swore she wouldnt lose it, but, as whenever we promise ourselves something, the worst always seems to happen. It started with a doll, a petite wooden doll her late mother had given her. The feel of it against her skin did nothing to bring back the warm embrace of her. A dress of embroidered orange silk, the stitching on it as fine and golden as a thread of Rapunzels hair or the spun gold of that millers daughter who had given her word in exchange for a name, her tiny painted face relentlessly smiling in sympathy. Since then she had never managed to hold onto anything for long. Each precious gift would go missing in time, no matter how extensively she clung to it, as a spider clings its sticky, furred, legs to a painted wall. Someone had taken it, it had been there and now it was gone, she remembered it clear as day, even though the dim night had already crept in, had muted the daylight. Innocence has flushed from her cheeks into a guilty crimson. There was no end to her excuses. After that it was an antique music box, the lid engraved with her initials in the cursive script of an antique bible or a medieval tapestry. It played a sweet tune as the tiny figure turned and swirled and spiralled, it had sent chills down her thin frame whenever she heard it. After its elusive disappearance she had heard the merry tune again, this time sinister, at night, but only ever when her eyes were tightly closed. She would reach out for it in longing, almost touching, her fingertips longing for the touch of the bitter, reassuring metal. Then it was gone. It started with a doll and it finished with a tiny golden ball. Perhaps it had fallen down the well. She remembered throwing it into the air yesterday morning, while she sat and hummed a tune at the edge of the black hole. She had peered in, hoping to see the splash of a tiny water snake she had seen once before, but the well was low, the black liquid could not be seen, and only a dropping pebble would reveal the true depth. A call from the house had prompted her to leave; perhaps she had left it there, perched on the side, peering into the abyss. Morning, the sun shone down, touching her ashen skin with its golden tendrils. Her father knew nothing about her missing gift; she knew it would break his ruby heart to hear of its disappearance. Shed searched and hunted all night with no luck. Maybe the vivid morning sun would cast its glow into the direction of her golden orb. Id do anything to get it back. She looked into the horizon, scanning her tired eyes across the emerald green earth. She could see the jagged form of something, developing in detail as it edged toward her. Movement, his thin body swerving and slithering towards her, his eyes as green as the ground he slipped across. His skin so smooth. His smile melted her. You are looking for something, he whispered, his red tongue caressing the soft flesh of his inner cheek as he spoke, looking for something I have. An unravelled palm looked like a spring bud opening to the sun, and there it was, growing and shrinking in his fleshy hold, the light ebbing and flowing off of it like the scales of an iridescent water-snake stirring below the surface of azure settled waters. Take it. She was Eve and he was the serpent, the orb a polished scarlet apple. A snake charmer humming an enchanting refrain. Take it. Green omniscient eyes embraced her body, her breathing slows, her blood feels as though it is trickling through her body like th e fresh, cool stream that ran beside her. She reached out, just as she had in her dreams, the same soft fingertips, the same enchanting melody, the same cool touch. His lips met hers. Inhaling the warm breath from her lungs. The blood drained from her eyes. She hugged the floor, her fingernails gripping to the hard earth, the world was spinning, she was falling, the gravity pulled her further down. A single tear flew from her eye into the sky. Then, she slept. He curled his body around her, jaws wide. The scales of his cracked skin rubbed against hers. A glow of a beady eye. A flick of a red tongue. A flash of those white-hot raw teeth, jagged and roughen. He engulfed her. And slinked away. Commentary Angela Carters stories have several very distinct elements. She often subverts characters traditional roles and values, teamed with rich description and imagery. The incredibly stereotypical characters in fairytales make it perfect for Angela Carter to take a different twist on. In my piece, the first Carter style technique I have used is the switching of tenses. While the story starts in the present tense, with It is late evening, very different to common narrative, it soon switches to past tense. It also switches between events that have happened recently or are happening to something that has happened long before, for example in the switch from the first paragraph being in the present tense and the second paragraph switching to a past event or story. This is similar to the way The Bloody Chamber changes between the current events and much earlier in the story. This makes the reader feel more involved in the story, as the present tense really puts them in the position of what is going on around them. As well as this technique, I used the technique of directly addressing the reader, which again involves them in the story more with the phrase whenever we promise ourselves something, the worst always seems to happen. This makes the reader think of their own personal issues helps them find a similarity with the main character. I also used a similar juxtapositioning of words, which help create a contrast. I described the feel of the music box as bitter, reassuring metal. This contrast creates a different image of the seemingly innocent item and makes it more complex to the reader, whilst also adding a sense of darkness. Because the image took place during a dream, I thought this phrase helped to encapsulate the overwhelming feelings of the dream/nightmare in a way that all readers can relate too but is difficult to express. In most typical fairytales the male characters are usually strong and desirable, and the evil characters are often female, ugly and cruel characters. In my piece I have created the villain as a man to subvert this. The villain, despite being oddly enchanting, has a strong negative side in description. I have portrayed him as a character that seems unnaturally charming but also someone to be wary of. This is a strong change from the normal fairytale males, usually obviously handsome and safe, yet my character still has some of the typical dominant male qualities, his eyes as green as the ground he slipped across. His skin so smooth., this phrase is not necessarily negative but strongly reinforces the idea of the true identity of the male. I also included a variety of different sentence lengths. Minor sentences have more impact and stand out; sentences such as There was no end to her excuses. In this case, the short sentence emphasises the situation of the character. I combined the power of three along with these minor sentences in the description A glow of a beady eye. A flick of a red tongue. A flash of those white-hot raw teeth. This style is similar to the way a person may take in the characteristics of a person they have met, a list of their most prominent features. I mixed some other myths and fairytales into the story when I said golden as a thread of Rapunzels hair or the spun gold of that millers daughter. This slightly sets the time and place of the story, as the character would have to have heard the stories to reference them. However, because of the lack of detail there is still some mystery in the time and setting. This is similar to the phrase in The Bloody Chamber when the main character describes the glass box telling the story of Bluebeard. When describing the male character, I wanted to portray an element of mystery to the form the character appeared in, as in many of Carters stories, the actual form of the character only becomes apparent near the end of the story, or sometimes not at all. In my story the form of the character at the end is rather obvious, with phrases like The scales of his cracked skin, although when previously describing him I tried to give him the serpentine elements but in a way so they could have been used to describe a real human being. This technique is very apparent in Carters Wolf-Alice and I wanted to achieve the same mystery as this with my story. The general tone of the story starts off fairly innocent, but as the story develops the darkness appears, perhaps with the introduction of the male figure. Also, the temptation of the female character was another common feature in most fairytales, and I imitated this in my piece. The way in which Carter shows dialogue makes the reader again feel involved. In my story, all the dialogue occurred during descriptions. I thought this flow of dialogue included the reader in the situation in the same way. Most common fairytales all have some kind of moral. Usually these morals are intended to teach children what not to do. For example, be careful what you wish for or things dont always appear as they seem. In my story I have played with this idea, as my piece is loosely based on the Frog Prince I have looked into the moral things are not always what they seem. In the original Frog Prince, the ugly frog turns out to be a handsome Prince. However, in my story I decided to make a significant twist. Infact the moral of my story was that sometimes things are what they seem, and sometimes people who appear suspicious are exactly what you think of them. Another point I tried to add was the idea of the enchantment being similar to that of Eve and the Serpent in the garden of Eden. The male characters charm is similar to that of the serpent in convincing Eve to take the apple. The golden orb also represents the apple of the story. This religious aspect of the story strongly relates back to the traditional fairytales which combined magic realism with strong religious views. In many traditional fairytale the replacement of a mother with a step-mother, or no mother at all, is very apparent. In my story I made reference to the lack of a mother figure when I said a petite wooden doll her late mother had given her. The feel of it against her skin did nothing to bring back the warm embrace of her. This is a common fairytale feature. In conclusion, I think my story showed many of the similar stylised techniques as Carters stories. The overall values of common fairytales were clearly apparent, but along with several elements that are similar to Carters own style.

Superconductor Definition, Types, and Uses

Superconductor Definition, Types, and Uses A superconductor is an element or metallic alloy which, when cooled below a certain threshold temperature, the material  dramatically loses all electrical resistance. In principle, superconductors can allow electrical current to flow without any energy loss (although, in practice, an ideal superconductor is very hard to produce). This type of current is called a supercurrent. The threshold temperature below which a material transitions into a superconductor state is designated as Tc, which stands for critical temperature. Not all materials turn into superconductors, and the materials that do each have their own value of Tc. Types of Superconductors Type I superconductors act as conductors at room temperature, but when cooled below Tc, the molecular motion within the material reduces enough that the flow of current can move unimpeded.Type 2 superconductors are not particularly good conductors at room temperature, the transition to a superconductor state is more gradual than Type 1 superconductors. The mechanism and physical basis for this change in state is not, at present, fully understood. Type 2 superconductors are typically metallic compounds and alloys. Discovery of the Superconductor Superconductivity was first discovered in 1911 when mercury was cooled to approximately 4 degrees Kelvin by Dutch physicist Heike Kamerlingh Onnes, which earned him the 1913 Nobel Prize in physics. In the years since, this field has greatly expanded and many other forms of superconductors have been discovered, including Type 2 superconductors in the 1930s. The basic theory of superconductivity, BCS Theory, earned the scientists- John Bardeen, Leon Cooper, and John Schrieffer- the 1972 Nobel Prize in physics. A portion of the 1973 Nobel Prize in physics went to Brian Josephson, also for work with superconductivity. In January 1986, Karl Muller and Johannes Bednorz made a discovery that revolutionized how scientists thought of superconductors. Prior to this point, the understanding was that superconductivity manifested only when cooled to  near  absolute zero, but using an oxide of barium, lanthanum, and copper, they found that it became a superconductor at approximately 40 degrees Kelvin. This initiated a race to discover materials that functioned as superconductors at much higher temperatures. In the decades since, the highest temperatures that had been reached were about 133 degrees Kelvin (though you could get up to 164 degrees Kelvin if you applied a high pressure). In August 2015, a paper published in the journal Nature  reported the discovery of superconductivity at a temperature of 203 degrees Kelvin when under high pressure. Applications of Superconductors Superconductors are used in a variety of applications, but most notably within the structure of the Large Hadron Collider. The tunnels that contain the beams of charged particles are surrounded by tubes containing powerful superconductors. The supercurrents that flow through the superconductors generate an intense magnetic field, through electromagnetic induction, that can be used to accelerate and direct the team as desired. In addition, superconductors exhibit the  Meissner effect  in which they cancel all magnetic flux inside the material, becoming perfectly diamagnetic (discovered in 1933). In this case, the magnetic field lines actually travel around the cooled superconductor. It is this property of  superconductors  which is frequently used in magnetic levitation experiments, such as the quantum locking seen in quantum levitation. In other words, if  Back to the Future  style hoverboards ever become a reality. In a less mundane application, superconductors play a role in modern advancements in magnetic levitation trains, which provide a powerful possibility for high-speed public transport that is based on electricity (which can be generated using renewable energy) in contrast to non-renewable current options like airplanes, cars, and coal-powered trains.

Essay about American History

Essay about American History Essay about American History A Chronology of American History: 15th | 16th | 17th | 18th | 19th | 20th 17th Century 1607 May 13: The first permanent English colony is founded in Jamestown, Virginia. 1619 July 30: Virginia's House of Burgesses convenes; it is the first legislative assembly in English North America. August: A Dutch ship carries 20 blacks to Virginia. We now know that these were not the first blacks to arrive in Virginia. 1620 May 21: The Mayflower Compact, signed by 41 adult males in Provincetown Harbor, Mass., represents the first agreement on self-government in English North America. December 26: The Pilgrim Separatists land at Plymouth, Mass. 1621 December 25: Massachusetts Governor William Bradford forbids game-playing on Christmas day. 1622 March 22: Indian attacks kill one-third of the English settlers in Virginia. 1624 John Smith publishes his General History of Virginia, New England, and the Summer Isles, which describes his rescue by Pocahontas. May: The Dutch establish the colony of New Netherland. May 1: The Maypole at Mare Mount. In what is now Quincy, Mass., Thomas Morton and others set up a May Pole, engaged in drinking and dancing with Indian women, and celebrated "the feasts of the Roman Goddes Glora, or the beastly practises of the Madd Bacchinalians," according to Massachusetts Governor William Bradford. Morton was deported to England. 1632 Charles I grants Lord Baltimore territory north of the Potomac River, which will become Maryland. Because the royal charter did not restrict settlement to Protestants, Catholics could settle in the colony. 1634 Massachusetts' sumptuary law forebodes the purchase of woolen, linen or silk clothes with silver, gold, silk, or lace on them. 1636 June: After being expelled from Massachusetts Bay Colony, Roger Williams founds Rhode Island, which becomes the first English colony to grant complete religious tolerance. 1637 November 7: Massachusetts banishes Anne Hutchinson for preaching that faith alone was sufficient for salvation. 1638 March: The first Swedish colonists settle in Delaware. 1654 The first Jews arrive in New Amsterdam, fleeing the Spanish Inquisition in Brazil. 1660 May: Massachusetts forbids the celebration of Christmas. December 1: Parliament adopts the First Navigation Act, which requires all goods carried to and from England to be transported on English ships and that the colonies could export cotton, ginger, sugar, tobacco, and wool exclusively to England. Other Navigation Acts were enacted in 1662, 1663, 1670, and 1673. 1661 September: Governor John Endicott orders an end to persecution of Quakers in Massachusetts, where three Quakers had been executed. 1662 A synod of Massachusetts churches adopts the Halfway Covenant, which permits baptism of children whose parents had not become full church members. 1664 Maryland adopts a statute denying freedom to slaves who converted to Christianity. A similar act was adopted by Virginia in 1667. September 7: The Dutch surrender New Netherland to the English, who rename the colony New York. The Dutch temporarily regained possession in 1673 and 1674. 1669 John Locke drafts the Fundamental Constitutions for the Carolinas, which combines a feudal social order with a stress on religious toleration. 1675 June 24: King Philip's War begins. Relative to the size of the population, this conflict between the New England colonists and

Leadership Essay Example | Topics and Well Written Essays - 1000 words

Leadership - Essay Example This is contested by Andersen (2006) who wrote that traits alone are not enough for effective leadership and they are only prerequisite. Traits only provide people with the potential for leadership. Goleman (2008) hypothesized that great leaders are naturally inclined to show interest in others and bring about positive feelings from these people. This then allows a strong show of support. He further mentioned that learning and practice on desirable leadership style can lead to enhanced performance of a potential leader. Thus, the Great Man Theory only explains a part of a successful leader. There are various factors that influence the development of a good leader (Goleman 2008). Cawthon (1996) stated that most important leadership capabilities and proficiencies can be learned and people can be educated along these as long as there is desire to learn and there are no apparent obstacles to learning such as a learning disorder. When studying the several circumstances that play an import ant role in the lives of the great leaders, it seems hard to believe that only inherent traits contributed to their success. There are too many variables that are considered to make effective leaders. The possession of certain inherent traits does not guarantee the success of leadership. Additionally, any leadership style can be successful as long as it recognizes the path to success. Strong leadership capability goes further than genetic inheritance. House and Mitchell (1974) proposed that successful leaders have the capacity to persuade and motivate others to willingly increase their efforts to contribute to the organisation. They further stated that this can be achieved through a leader’s inimitable focus toward fulfilling the needs of their associates by providing the needed training, supervision and support. These motivate followers toward higher levels of performance. Researchers often take on the assumption that leadership comes inherently with individuals, that some o f them .possess a set of inherent traits that enable them to be recognized as great leaders. For many years, this assumption led social scientists to focus only on these traits. However, because of inconsistency in the results research, the trait theory was discarded in favor of the theory that leadership development does not espouse inherent leadership traits but only leadership styles or behaviors that may be developed and changed completely from one setting to another. There is also the notion that a person who is a leader in one setting may be a follower in another in the same way that traits which are practical in one situation may not be helpful in others. Thus, leaders are not born with any specific traits that determine effective leadership (Howard & Wilson, 1982). Even without inherent traits, a person can be an effective leader as long as he can adapt to the unique demands of ever changing organisations. According to Howard and Wilson (1982), leaders must have the aspirati on to lead. In order to be effective, a person must want to lead. However, even if a person has the ability and education to lead but has no enthusiasm, success will most likely not be achieved. History has presented the crucial roles that leaders and leadership play in the success of an organisation – these can be in the context of business ventures, educational settings and

Global Exploration and Global Empires 1500-1700 Essay - 1

Global Exploration and Global Empires 1500-1700 - Essay Example The use of African slaves was very favorable for planters. First, Blacks were better adapted to wearisome physical work in the hot climate than white Europeans or Indians; secondly, taken out far from the habitats of their own tribes, not having any idea how to come back home, they were less inclined to escapes. In the middle of the XX century almost all the black population of the American continent was the descendants of the slaves taken out from Africa. In total about 13 million African slaves were imported to the British North America and later to the USA. On average, only one from 3-5 captured slaves was brought to a plantation, the others perished during the capture and transportation. According to the estimates of researchers, as a result of a slave trade Africa lost about 80 million lives (Slavery Timeline). In Europe the use of a slave labor was resumed and mass slave trade, which prospered up to the XIX century began. Africans were captured in their native lands, loaded on ships and sent to destination. The Irish captured by British during the conquest of Ireland in 1649 — 1651 prevailed among "white slaves". Intermediate position between exiled and free colonists was occupied by the "sold in a service": people sold their freedom for the right to move to colonies and to work it off there again. Considerable part of the Irish population, including women and children, was turned into white slaves and took out to English colonies in West Indies. During this period People in Ireland cost less than wolves: English soldiers were paid 5 pounds for the head of "the rebel or the priest" and 6 pounds — for the wolf ‘s head (Slave Trade Statistics). In the XVII—XVIII centuries Dahomey played a significant role in a slave trade and conducted fierce fight against the rivals: Allada, which was attacked by Dahomey in 1724 for the first time and captured in 1730, and Whydah captured in

Learning Theories and Emergent Theories of Learning Essay

Learning Theories and Emergent Theories of Learning - Essay Example Starratt (2008) posit that decontextualized and depersonalized learning method in instruction posed an inauthentic, dishonest, disrespectful, and, hence, do not a virtuous learning approach (p. 1). Learners should be taught to discover the relevance and goodness of dialogue between learners and the relation of intelligible realities to their mutual interdependence (Starratt, 2008, p 1). These learning processes need learning-centred and extensive monitoring of their academic progress, as well as, diagnose the learning difficulties of students (Masters, 2005). Standard academic development is relevant to meet the needs and teachers must be constructivist broad-based leaders inside every classroom as a strategy (Lambert, 2003). The learning-centred approaches refers to the nurturing of students for clarity of knowledge, skills, and understanding including the academic design, diagnosis, and monitoring of individual progress (Lambert, 2003). Hence, it’s important that teachers po ssess quality teaching materials for effective teaching strategies (Lambert, 2003).Gross (2004) observed that numerous educators and schools are not quite supported by the government and hence, confront serious disruption in their roles as educators and expert managers of educational institutions. With lacking supports, educators are pulled from completing and achieving their targets hence, demoralizing students, teachers and managers (Gross, 2004). Education can only be successful when institutions are supported by the government to make it an effective and efficient service institution. This value-oriented education will put all learners within the positive tract and will motivate them to become pro-active stakeholders in a community that is struggling to remove the vestiges of poverty, illiteracy, social inequities, and ecological-related problems (Starrat, 2005). This can bring about the highest form of commitment and leadership in all endeavours and context. Teachers therefore play a crucial role in nurturing values and principle-centred knowledge for learners to genuinely and authentically live their lives in a deeply meaningful and value-centred sense of purpose. But these ideals can only be undertaken with support for change management; curriculum-instruction assessment; professional development practices; innovative pedagogical approach; and, education management (Gross, 2004; Wehlage, Newmann, & Secada, 1996). The learning process should be innovative and motivating for an authentic outcome using learners and instructors’ skills and ability to innovate means to elicit or generate the authentic outcome of education (Parens, 2005; Glendinning, 2005) Module 3: Learning Theories and Emergent Theories of Learning Teachers must develop a curriculum that is supported of an environment where students are allowed full participation, dialogue, inquiry, reflection, and rediscovering of the transformational models to revive their sense of purposiveness in this world (Tuana, 2007; Wehlage, Newmann, & Secada, 1996; Ornstein & Hunkins, 2004). Everybody has the notion that teachers are there to engage learners to improve their crafts, to make them action and result-oriented, and to inculcate on learners to be adaptive to changes and to possess such disposition of assuming responsibility to question falsities. It’s also from this notion that those who’d found the need to rise up from challenges brace themselves to respond to perplexed and multidimensional concerns on civilization, poverty, lack of access to quality education, conflicts and war, excessive human rights

The Book of Kells and its influence on the State of Arizona Research Paper

The Book of Kells and its influence on the State of Arizona - Research Paper Example It contains full pages of extraneous decoration for the canon tables; symbols and text of the evangelists Matthew (the Man), Mark (the Lion), Luke (the Calf) and John (the Eagle); the opening words of the Gospels; the Virgin and Child; a portrait of Christ, and complex narrative scenes such as the earliest to survive in gospel manuscripts which corresponds the arrest of Christ and his temptation by the Devil. The word Christ has been abbreviated with letters Chi Rho in medieval manuscripts and Chi Rho page is the most famous page in medieval art which introduces Matthew’s account of the nascence. However, the book is not a full copy of the Vulgate and contains a number of variations from the Vulgate and also some uncorrected errors. It is assumed that around 30 folios of the text had been lost in the medieval and early modern periods and some pages are deteriorated.3 According to experts, the handwriting differs throughout the text therefore the artwork seemed to have produced by at least three different artists.4 Today the manuscript contains 340 folios with 330 by 250mm dimensions, and scriptures are written with a range of pigments including yellow, red, green, purple and black. The manuscript is believed to have created by Celtic monks in year 800, but the date and origin of the book has been a controversial issue. The widely accepted belief is that the text creation might have started at Iona from where it was brought to Abbey of Kells, when Vikings invaded the island of Iona, where the artwork might have been continued to be undertaken. The text was revered at Kells as a souvenir of Saint Columba throughout the medieval periods. The Book of Kells is the considered to be one of the finest manuscripts and described as â€Å"the chief treasure of the Western world†. The Annals of Ulster record stealth of the book in year 1006 and that it discovered again after many years, stripped off its ornate gold. Around 1653, the Book of Kells was sent to Dublin, Ireland for safety concerns and after few years it was brought to Trinity College, Dublin where it has been on display in library over there. The text has been bound in four volumes, since 1953, of which two volumes can commonly be seen in library, one opened to display a major decorated page, and the other to show two pages of script.5 A quote of Sir Edward Sullivan demonstrates the concept of how mind-bending the artwork of The Book of Kells: "The finest draftsmen of the entire world have tried to recreate the Chi-Rho page, and have failed." Anyone in today's modern world could not recreate it as it takes an ineffable artist working in the Middle Ages to create something.6 However, in 1951, the first facsimile of the Book of Kells was produced by a Swiss publisher, Urs Graf Verlag Bern, in black-and-white photographs and color reproductions as well. Second facsimile in full color was produced in 1974 by photographers Thames and Hudson in Dublin, and included all the full-p age detailed illustrations and also an ornamentation representative section in the manuscript. In the 1980s, Faksimile-Verlag Luzern produced with permission from Trinity College,

The Semantic Web and Relational Databases essay

The Semantic Web and Relational Databases - Essay Example I think maybe when you've got an overlay of scalable vector graphics - everything rippling and folding and looking misty on Web 2.0 and access to a semantic Web integrated across a huge space of data, you'll have access to an unbelievable data resource." (Wikipedia, 2009) World Wide Web consortiumW3C is working on this technology to make it more efficient, extendable and presentable to the users. Semantic Web enables the user to find, share and combine information on the web. It is based on machine readable information and uses XML technology to define customized tagging. It provides the common language to represent how the data is related to real world objects. The central idea is to provide the specific user requirements from the web. It is not a communication between web pages, but it describes relationships between objects. A software database technology includes some aspects through which semantic web works. Data which is transferred by human intervention or by machine is portably collected in a data space. Data spaces are domain specific. They are identified by an identifier. The data which can be viewed in object oriented view is called a data space. Linked data is a part of the Semantic web which is identified by URI (Uniform resource identifier). The Data or object existed in the data space must be movable and can be identified and cited by the uniform resource identifier whenever required. Open linked database, which is called as â€Å"ODS† is a distributed, collaborative web application platform, social network and content management system. It has been written using VSP, VSPX and the open link AJAX toolkit. It incorporates wide range of industry standards for data access and management (Wikipedia, 2009).

The Great British Pub Essay Example | Topics and Well Written Essays - 3000 words

The Great British Pub - Essay Example veral pubs to its brand and offers a wonderful mix of traditional food and exotic drinks most wines are hand selected and carefully brewed to meet the varying tastes of customers across the country and visiting tourists. To meet the next challenges that lie ahead in the pub retail industry, the operations department has to come up with up-to-date innovations ascribed to the products and services offered. There are several modus operandi for innovating services in the pub market arena. The great British pub can and should redefine its strategy to fit the current market trends and deliver maximum profits. As opposed to the current strategy of only offering mostly food and drinks, it must develop a new strategy that targets even those who seek accommodation. The firm’s mission and vision statements must reflect and include its stakeholders. These measures should be driven using the bottom up approach in order for the employees to own the new strategy. Openness in setting targets should involve everyone that directly or indirectly attached or associated with the great old British pub. The strategy must take into consideration the suppliers, the government restrictions, outsourced service partners, the highly esteemed workforce and most importantly, it should revere its customers. The products offered by the pub are mainly drinks and food. These products must be offered in a manner that treats customers with respect. The beers and whiskeys must concentrate on the particular tastes preferred by the customers according to recent market researches. Quality can be made a side-by-side buzz word for the pub and as such the business can establish itself as completely unique pub in the world. When quality becomes a part of an organization, customers are attached to the enterprise since they are assured of getting value for their money. This can be done by sampling tastes all over the world so that not even tourists are left unattended. Once the traditional foods and drinks

To measure numerical results for ZR processing schemes with imperfect CSI, and in a multi-cell scenario. 1.4 Main Contributions This thesis has contributions to knowledge in three research issues for LS-MIMO system, which are the new refined circuit power consumption model, energy efficiency maximisation with ZF processing scheme, and deployment of imperfect CSI case and symmetric multi-cell scenario. Those main contributions of this thesis are summarized and elaborated more detail as follows: The circuit power consumption is the sum of the power consumed by different analogue components and digital signal processing. The new refined model of the total power explicitly described how the total power consumption depends non-linearly on number of number of UEs, number of BS antennas, and transmit power. The closed-form EE expression under the assumption of ZF processing scheme is employed in the uplink and downlink for optimal number of UEs, number of BS antennas, and transmit power for a single-cell scenario with perfect CSI. This option is driven by analytic convenience and numerical results likewise which are close to optimal. Analysis of imperfect CSI case and symmetric multi-cell scenarios deployment are extended using the same method above. A New achievable rate derived for symmetric multi-cell scenarios with ZF processing. 1.5 Research Methodology In the first stage of the research, literature review of past and current works on the area of MIMO, MU-MIMO, and LS-MIMO are extensively conducted to broaden the perspective on such areas of study. Furthermore, state of the art related to those addressed issues are deeply studied and intensively explored during this period. Following the literature review phase, implementation starts with formulating the EE maximisation problem. A new refined circuit power consumption model is proposed. All this then used to compute closed-form expression for the optimal number of UEs, number of BS antennas, and transmit power under the assumption of ZF processing scheme. The testing stage starts with simulation. All the simulations were performed using Monte Carlo Simulation techniques in Matlab. Monte Carlo simulation can handle very complex and realistic. Monte Carlo Simulation were executed for all the investigated schemes with perfect CSI, for ZF with imperfect CSI, and in a multi-cell scenario In the validation stage, numerical results are used to authenticate the theoretical analysis and make comparison amongst different processing schemes. 1.6 Thesis Structure This thesis comprises of six chapters, where each chapter is inter- dependent.

LS-MIMO An Overview 2.1 Introduction to LS-MIMO Wireless communication is one of the most successful technologies is one of the most successful technologies in modern years, given that an exponential growth rate in wireless traffic (known as Coopers law) [1]. This trend will certainly drive by; for example, augmented reality and internet-of-things [1]. Figure 2-1:[6] 2.2 Antenna configurations Radio-Frequency (RF) circuit is usually connected to its physical antennas through an RF cable in a passive AA. A Remote Radio Unit (RRU) in with a Baseband Unit (BBU) has become a preferred configuration recently [1]. 2.3 Channel Measurements Realistic channel measurements have been carried out in in an effort to identify the main characteristics of LS-MIMO channels [15] 2.4 Channel Model Three types of channel models have been used for evaluating the performance of wireless communications systems, namely the Correlation-Based Stochastic Model (CBSM), the Parametric Stochastic Model (PSM) and the Geometry- Based Stochastic Model (GBSM) in [1]. 2.5 Processing Schemes Precoding LS-MIMO is based on linear processing at the BS. BS has observation of the multiple access channels from the terminals [6]. The BS applies linear receive combining to discriminate the signal transmitted [6]. The simplest choice is maximum ratio (MR) combining by adding the signal components coherently. In [6], this result signal amplification proportional to. Energy Efficiency Problem Literature Review 3.1 System and Signal Model The uplink and downlink of a single-cell multiuser MIMO system operating is considered over a bandwidth of B Hz [15]. 3.2 Channel Model and Linear Processing The M antennas at the BS are spaced apart such that the channel components between the BS antennas and the single-antenna UEs are uncorrelated [15]. The channel describes propagation channel between antenna at the BS and the UE. We assume small scale fading distribution [15]. 3.3 Uplink In [15], under the assumption of Gaussian, linear processing, and the perfect CSI, the achievable uplink rate of the th UE is (3.6) the pre-log factor accounts for pilot overhead and is the fraction of uplink transmission [15]. In addition, (3.7) 3.4 Downlink A normalized precoding vector and the downlink signal to the kth is assigned a transmit power of . In [15], assuming Gaussian codebooks and perfect CSI the achievable downlink rate of the kth UE with linear processing is (3.13) 3.5 Problem Statement The EE of a communication system is measured in bit/Joule and the average total power consumption (in Watt = Joule/second) [15]. The total EE of the uplink and downlink is (3.20) Energy Efficiency Maximisation-Techniques 4.1 Realistic Circuit Power Consumption Model The sum of the power consumed by different components and signal processing is the circuit consumption is [15]. A power consumption model is proposed (3.22) 4.2 Energy Efficiency Maximisation with ZF Processing The EE maximisation problem is resolved under the assumption that ZF processing is employed. This solution is driven by analytic and the numerical results [15]. For ZF processing, Problem 1 reduces to (3.30) 4.3 Extension to Imperfect CSI and Multi-Cell The analysis is prolonged to single-cell scenarios with imperfect CSI. A new achievable rate is derived with ZF forcing processing. The achievable user rates in single-cell scenarios with imperfect CSI [15]. (3.52) Simulation Setup and Numerical Results 5.1 Simulation Setup Simulations used to validate the system design guidelines under ZF processing and to make comparison with other processing schemes [15]. Numerical results provided under both perfect and imperfect CSI, and for single-cell and multi-cell scenarios [ 15]. For stimulating ZF, and MRT analytic results were executed and MMSE, and Monte Carlo simulations were performed to maximise EE [15]. 5.2 Single-Cell Scenario The chosen deployment model validated. 5.3 Multi-Cell Scenario A lot of studies have been carried out. Conclusions and Future Research 6.1 Conclusions This thesis focuses on the energy maximisation improvement of the LS-MIMO systems to cope with energy maximisation problem. The thesis has three main contributions; all are elaborated in detail. 6.2 Future Research Several recommendations, which may guide to the future research directions on LS-MIMO systems.

Financial Accounting Essay -- Business and Management Studies:

Financial Accounting Financial accounting or ‘book-keeping’ is the process of recording financial transactions from the day-to-day operation of a business. The sale of goods to a customer and the subsequent settlement of the debt are two examples of financial transactions. Sales Accounting When credit sales are made to customers, a record needs to be kept of amounts owing and paid. Payment is normally requested with an invoice. An invoice usually gives details of goods supplied, quantities, prices and VAT. Credit sales are usually made on weekly a basis, which means that the customer has to pay within that period to obtain the discounts, if any offered. Overdue payments need to be chased, so sales accounting systems normally produce reports analysing the indebtedness of different customers. Debt control is vital to business profitability and computerised systems can produce prompt and up-to-date reports as a by-product of the main application. Human Resources --------------- The human resources (personnel) function is responsible for the selection (usually by interview), recruitment, training and development of staff. Personnel records on employees will store all the information needed by Salaries and Wages to make the correct payments to employees; this will include details of, for example, gross salary, tax code, statutory sick pay and holiday entitlement. Depending on the size of the organisation, information may also be held concerning: qualifications, courses attended; and career development plans. Design ------ The design function is present where an organisation develops its own products and services; a trader who simply buys and sells goods has no need of a design team unless designing logo’s etc which maybe carried out by another firm. Design is part of the research and development (R&D) function, which is vital to organisations wishing to radically develop their product range. The nature of design teams depends on the product or service being designed. The skills and talents of a car design team are clearly very different from those of a team designing a cover for a magazine. Production Markets for a business’s products should ideally, drive the production function. In other words, it should be geared to produce the necessary mix and quantities of products required by customers. If goods ar... ...ons need specialist staff to develop, introduce, maintain and update the various systems that make use of information technology. The responsibilities of ICT Services are much broader than those traditional held by wholly centralised computer services or data processing departments because communication is a larger part of IT with the introduction of the internet and E-mail amongst other things.. The development of cheaper and more powerful microcomputer systems has resulted in computer facilities being distributed more widely. For this reason, ICT Services needs to provide a much more flexible service and support user systems at the point of use. For example, uses of network workstations need support when equipment, such as a shared printer, breaks down or they may require help in the use of software on the network. This contrasts with a centralised department, which holds all the computer equipment, carries out all computer processing and restricts user access to specialised applications, run through dedicated terminals. ICT Services may be known variously as Computer Services, Management Information Services or less commonly now, the Data Processing Department.

The Color Pulpe Essay -- Character Analysis, Celie

The rivalry between the right of men and women has been an hardily fight for decades. In The Color Purple, Alice Walker portrayed a patriarchal society made by and for men. In this system women struggle to obtain a voice. An example is the protagonist, Celie, who from the beginning of her life experience sexual, mental and physical abuse from her step-father and also by her husband. As a result of this unequal system where women are consider nothing without a man, Celie develops a passive character only doing what men order. However, with the unconditional support of the women around her, she finally attain her liberation and independence. As a result, her emancipation generate an opportunity to make her realize her individuality and inner strength. From the beginning of the novel it is show the patriarchal and misogynist society of which Celie is part. This harmful environment affect many aspects of her life. The initial system that is expose is the patriarchalism through her step-father, Alphonso, who is characterize as a mean, opprobrious and malicious old man. He is the first one who sexually abuse Celie. â€Å"Just say You gonna do what your mammy wouldn't. First he put his thing up against my hip and sort of wiggle around. Then he grab hold my titties. Then he push his thing inside my pussy.†(1) Alphonso aggressively took away the virginity as well as her innocence since there weren't any familiar attachments with her. Moreover, aside from being a sexual abuse is also physiological seem he make her believes that is her duty to give him the satisfactions that her mother refuse to. Furthermore, Alphonso also damage Celie emotionally by taking away her children, Adam and Olivia as well as making her feel inferior compare ... ...e as a women duty and not make it for man. â€Å"I use to try to sew along with mama cause that's what she was always doing. But everybody laughed at me. But you know, I liked it.†(279) To become part of the society he abandon something that he like. His perspective of the world change completely as well as he opinion of women. He begins to make t-shirts and with each stich he forget and forgive as well as fixing his mistakes. This way showing the extended metaphor of making t-shirts that represent forgiveness and repentance to go along with pants make out of love. After all, Mr.____ understood that that was a stupid rule and that as Celie he will not care about other people opinions but his. To establish equality is a difficult task in our society but is not impossible. A place where women and men could stand at the same level would make our society healthier.

Potential Cognitive and Memory Enhancing Property of the Caulerpa Lentillifera (Lato) & Kappaphycus Alvarezii (Guso).

CHAPTER I INTRODUCTION Rationale It is true that some of us get more forgetful as we age. It may take longer to learn new things, remember certain words, or find our glasses. These changes are often signs of forgetfulness. Brain scientists believe that the effects of normal aging on memory may result from the subtly changing environment within the brain. With aging, the brain seems to lose cells in areas that produce important neurotransmitters, upsetting the brain’s delicate balance of these chemical messengers. Other changes occur in the brain’s white matter, which is made up of nerve cell fibers, the â€Å"telephone cables† of brain cells through which communication with other cells takes place. Just how these changes affect memory is not entirely clear, but it may be that they decrease the efficiency of cell-to-cell communication. What the scientist knows is as we get older, our capability to lay down fresh memories may be affected, making it more difficult to learn new things. It’s not so much that we forget more easily, but that we may take longer to learn the information in the first place A lot of studies have been made in different substance for its potential property on enhancing memory and cognition. Docosahexaenoic acid is one of them. DHA is the most abundant omega-3 fatty acid in the brain. DHA is believe that it could maintain memory and support overall cognitive health. A carotenoid namely fucoxanthin increase the amount DHA in the biological system without intake of fish oil supplementation. It is also consider that low carotenoid levels could play a role in cognitive impairment. Phytochemicals such as antioxidants polyphenolic compounds flavonoids occur all over in foods of plant origin like fruits and vegetable, carotenoids, vitamin E and vitamin C have also a possible in improving age-related neurological dysfunction. These substances could also be found in marine algae and other marine organism. DHA is mostly found in the fish oil but the DHA originates from the photosynthetic and heterotrophic microalgae and macroalgae that the fish ate and other marine creature. Phytochemical such as flavonoids is found also in algae. Knowing about this there could be a possibility for its memory and cognitive enhancing property. Eating seaweeds could have its benefits. It is time to get to know the seaweeds known in the Filipino tables which are Caulerpa lentillifera (lato), Kappaphycus alvarezii (guso) and lukot although everyone calls it a ‘seaweed', â€Å"lukot† is anything but a the ‘secretions' of the creature dongsul/Sea Hare (Dolabella auricularia) and it is not an algae but it eats algae. With all this information there could be a possibility for its memory and cognitive enhancing property. Thus this study is to be conducted. A. kappaphycus alvarezii (Guso)B. Caulerpa lentillifera (Lato) www. ruffordsmallgrants. orgwww. backpackingphilippines. com C. Egg mass of Sea Hare (Dolabella auriculari) (Lukot) www. marketmanila. com Fig. 1 A, B, C: Seaweeds and Egg Mass Used in the Experiments Objective of the Study This study aims to determine the memory and cognitive enhancing properties of Caulerpa Lentillifera (lato), Kappaphycus alvarezii (guso) and and egg mass of Sea Hare(Dolabella auricularia) on mature albino mice. 1. To determine the average time at which the mice were able to complete the task after the allotted period for the consumption of the pigeon pellets, Caulerpa Lentillifera (lato), Kappaphycus alvarezii (guso) and egg mass of Sea Hare(Dolabella auricularia). 2. To compare which of the treatment Caulerpa Lentillifera (lato), Kappaphycus alvarezii (guso) and â€Å"lukot† egg mass of Sea Hare(Dolabella auricularia) have more cognitive and memory enhancing property. Significance of the Study The importance of the study is to help us reveal the potential cognitive and memory enhancing property of the Caulerpa lentillifera (lato) & Kappaphycus alvarezii (guso). Once its memory-cognition enhancing property is determine, this study promotes the consumption of edible eaweeds and other marine creatures to be part of the diet of average Filipino citizen like the Japanese people. Incorporating it through our daily meals could be use as a preventive measure away from dementia, Alzheimer’s and other memory-cognitive decline diseases. Moreover this study will present additional information to the other researchers with their studies in improving the memory & cognition and those researchers doing investigation & experimentation on Caulerpa le ntillifera (lato), Kappaphycus alvarezii (guso)and egg mass of Sea Hare(Dolabella auricularia). Scope and Limitation The study only focuses on Caulerpa lentillifera (lato), Kappaphycus alvarezii (guso) and and egg mass (lukot) of Sea Hare (Dolabella auricularia) and its cognitive-memory enhancing property. The seaweeds and the egg mass will be purchased in Carbon Public Market. The experimentation will takes place in University of San Carlos- Animal House, Pharmacological Testing Room where there is sufficient air, light and ventilation and the testing period will take 20 days. The mature albino white mice will be coming from one single source and will weigh 25-30grams. The method will be use in measuring memory and cognition will be Morris Water Maze. The time that the rat reaches the platform is used as the basis of analysis on the memory-cognitive enhancing property. This study only provide information on the effectiveness of the macroalgae Caulerpa lentillifera (lato) & Kappaphycus alvarezii (guso) and egg mass (lukot) of Sea Hare(Dolabella auricularia) on their cognitive-memory enhancing property. Definition of Terms Cognition- A term referring to the mental processes involved in gaining knowledge and comprehension, including thinking, knowing, remembering, judging and problem-solving. DHA (Docosahexaenoic acid )-An omega-3, polyunsaturated, 22-carbon fatty acid found almost exclusively in fish and marine animal oils. Latency- The amount of time a message takes to traverse a system. Memory- Refers to the processes that are used to acquire, store, retain and later retrieve information. There are three major processes involved in memory: encoding, storage and retrieval. Non-sequential- Not in logical order or sequence. Spatial- With reference to space or arrangement in space. Quasi-random- A low-discrepancy sequence. CHAPTER II REVIEW OF RELATED LITERATURE One of the memory & cognition decline is caused by oxidative stress and epigenetic changes. Multiple lines of evidence suggest that progressive oxidative damage is a conserved, central mechanism of age-related functional decline moreover; genes that mediate oxidative stress responses and DNA damage repair constitute the largest class of genes up regulated in the ageing human prefrontal cortex. Dietary antioxidants can suppress many age-related gene expressions and can reduce cognitive decline and prevent oxidative damage to the brain in ageing rats (Bishop et al. , 2010). Eating food rich in phytochemicals improves the aged-related neurological dysfunction including the most devastating of these, are Alzheimer’s disease [AD] and Parkinson’s disease [PD]. Phytochemicals such as consumption of dietary antioxidants polyphenolic compounds (flavonoids) occur ubiquitously in foods of plant origin (fruits and vegetable), Carotenoids, vitamin E and vitamin C (Youdim and Joseph, 2001) A study was done showing the relationship between cognitive performance (assessed by the Mini-Mental State Examination, Trail Making Test Part B, Digit Symbol Substitution, Finger Tapping Test, and Word Fluency Test) and different plasma carotenoids (lutein, zeaxanthin, b-cryptoxanthin, lycopene, a-carotene, and trans-bcarotene and cis-b-carotene) in a healthy elderly population. Logistic regression showed that participants with the lowest cognitive functioning (25th percentile) had a higher probability of having low levels of specific plasma carotenoids (,1st quartile): lycopene and zeaxanthin. This shows that Low carotenoid level in the blood could be the cause of cognitive impairment. (Akbaraly, et al. 2007). Fucoxanthum a carotenoid extracted in macroalgae by using of powdered seaweed (Undaria Pinnatifida) with chloroform/methanol (2:1) v/v. Undaria lipids containing the Fucoxanthin 9. 6% was obtained from the powdered seaweed while 78% from the crude. Fucoxanthin also enhances the amount of DHA in the liver. This shows the chance of dietary fucoxanthin stimulated increase DHA (docosahexaenoic acid) in biological system without direct DHA supplementation. DHA is naturally originate in the body in small amounts, and is the most abundant omega 3 fatty acid in the brain. DHA oil is abundant in some marine microalgae (Miyashita, et al. 2008). A Twenty-four week supplementation with 900 mg/d DHA improved learning and memory function in age related cognitive decline (ARCD) and is a beneficial supplement that supports cognitive health with aging and with Alzheimer’s disease. The omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are orthomolecular, conditionally essential nutrients that enhance quality of life and lower the risk of premature death. They function exclusively via cell membranes, in which they are anchored by phospholipid molecules. DHA is proven essential to pre- and postnatal brain development, whereas EPA seems more influential on behavior and mood. Both DHA and EPA generate neuroprotective metabolites. In doubleblind, randomized, controlled trials, DHA and EPA combinations have been shown to benefit attention deficit/hyperactivity disorder (AD/HD), autism, dyspraxia, dyslexia, and aggression. For the affective disorders, meta-analyses confirm benefits in major depressive disorder (MDD) and bipolar disorder, with promising results in schizophrenia and initial benefit for borderline personality disorder. Accelerated cognitive decline and mild cognitive impairment (MCI) correlate with lowered tissue levels of DHA/EPA, and supplementation has improved cognitive function. Altern Med Rev, 2007). Twenty weaning Sprague Dawley (SD) female rats were randomly divided into two groups and fed either with a diet that was adequate in LNA (n-3 Adq) or with a diet that was deficient in LNA (n-3 Def). In the MWM test, the escape latency of both groups gradually decreased over the testing period, indicating an improvement in performance for both groups. In general, the n-3 Adq group had shorter late ncies to locate the escape platform than the n-3-Def rats (P
