Andrew Jackson Essay Bad President Example For Students

Andrew Jackson Essay Bad President The CrucibleMany years ago, the culture and atmosphere was amazingly different. The expectations of people and communities are extremely high. During the Puritan times, many laws and regulations existed pertaining to government, religion, and witchcraft. In the play, The Crucible, by Arthur Miller, the one word that best describes the Puritan beliefs and the community structure is strict. The Puritan government during the time of this play is a theocracya government of God, run by the towns minister. This means that the people cannot elect their own leaders. In The Crucible, the minister of the town is Reverend Samuel Parris. Mr. Herrick says to Danforth, Mr. Parris command me, sir. I cannot deny him. This shows that he, Mr. Parris, holds a definite authority over Mr. Herrick. In this theocracy, the people have to obey the minister and his appointed colleagues no matter what. The townspeople will be condemned by the government if they can not recite the Ten Commandments whenever they are asked to do so. The government of Salem basically was the Church. From the church or the government there are many laws made pertaining to witchcraft. It is believed that if he or she is to dance, he is controlled by the devil. The subject of dancing is what gets the girls into trouble in the first place. The girls are seen by Parris dancing and conjuring evil spirits in the woods. Wi tches are what the girls are called by the people of the town. After they were caught, Parris goes upstairs to call Betty, his daughter, and Abagail, his niece, but Betty will not wake. This is when the Christie 2townspeople cry witch against her (Betty). Abagail says to her Uncle Parris, The rumor of witchcraft is all about. They think the devil has taken over the mind and soul of Betty and that is the reason she sleeps so soundly. The community that this play takes place in also believes that poppetsdollsare a sign of the devil. These are just ordinary dolls with regular human characteristics, but the people believed that the bodies and especially the faces of these dolls were rude mockeries of the human structure. Witchcraft and demonic ideas or beliefs are not to even be thought of during these times; severe punishment is the wrath of such things. Puritans must also attend the designated church services regularly. These are held on Sundays, from sun-up until sundown. If one fails to be in attendance, he will be punished accordingly. The Reverend Parris says, There is obedience or the church will burn like hell is burning. During the common folks spare time, they will not sit, read, or take part in any leisure activity unless they are studying or reading from their bibles. People believed that the common folks should not even have spare time. It is believed that laughing in church is also a sin. One might be hung for such an act. The Puritan religion is an incredibly strict religion. In the play by Arthur Miller, The Crucible, all of the beliefs and community structures are unbelievably strict. The minister of the town and the church rules the town as the government. Witchcraft is an act that should not even be thought of in Salem. The religion of the town is so strict that one may not even laugh in church. During the Puritan t imes, if the rules and regulations are broken, the punishment is made so severe that the other people in the town will be intimidated so that they will not commit the same crime.

Autobiography - The Separation Essay

Autobiography The Separation Essay Have you ever wondered if two people in love can stay together for life? In marriage, it is very common for husband and wife to vow to be with each other until one dies. However, there are studies that show that 8 out of 10 couples get divorced after the span of 1 to 20 years. This happened to my parents, they separated, this was when i was in the 8th grade leading to my first year of high school. I remember that day as if it was yesterday, a Wednesday afternoon. My sister Aixa and I had arrived home from school, as we strolled in through the front door we could smell the deliciousness of the ham and cheese sandwiches my grandma had ready for us. Later on, around 6 oclock, I was doing my english homework when my mother got to the house. She was always very drowsy and tired, work left her like that, and so commonly she would sleep as soon as she got home. This would make my mad upset and so they soon enough stopped kissing, stopped hugging, stopped talking. My father had also arrived home around an hour later, he went into his bedroom where my mom was resting and they talked for hours, which was a first in those past few months. They called for us and we all sat in the living room with the big plasma television. Mandy, Aixy ,  he exclaimed, calling us by our nicknames. We have decided to separate, you guys are already aware how much we dispute, it is not that we dont want to, but we dont have that spark anymore.   By that time my sister had broken into tears, screaming. Why? Why? Stay together for me! Please!   My mom put her hand up as a sign for her to be quiet as she replied. I simply do not love him anymore.   Everyone was quiet, the only sound was the couch creaking as I stood up and ran out the door. I thought I heard my parents call out to me, but I dont remember well. It was drizzling, and as I traversed through the cement I felt something cold stain my cheek, a tear, not a raindrop, but a tear. And soon came many ot hers, flooding my face with salty droplets. I hugged my hands to my chest and convinced myself I was going to be okay, I was going to move on and get past this hurtful event. I eventually walked back home where my parents yelled at me, and then hugged me. Months passed and my mother, sister and I finally moved. We moved into a cozy little apartment for three, every night I would remember my dad and how I didnt live with him anymore, I was very disappointed. But a year later i got used to it and I realized that it was okay for people to not love each other anymore, thoughts and ideas come and go, isnt it the same with love?

Pd film Movie Review Example | Topics and Well Written Essays - 500 words

Pd film - Movie Review Example The primary character in this case is Max Klein, one of the survivors after the plane crash. On realizing that the plane is on a crash course and there is minimal chance of survival, he gets comfortable with the idea that his life is going to be ended. In this situation, Max did not want it to be that he was the only one. This is because there were a whole lot of passengers who were scared by the situation at hand. It is at this point that we see the power of thought and the belief system, which a person has, working for them. Max is of the opinion that he is going to die and he has willingly accepted the fact. In this same case, he offers the other passengers a semblance of consolation. The other way through which this event seems to have changed the life of Max is by letting him do away with some of the fears, which he had. In this case, the fear, which is in question, is the fear of flying. This is something, which is exhibited when he declines the tickets, which were offered to him for the purpose of transport to San Francisco. He clearly states that he does not fear flying anymore. What this shows to the normal person is that it is of the essence to let of the fears, which act as barriers to the development of a person. The reason for this is that it may be difficult for the individual in question to make any significant progress in his or her life. This is simply because he or she is tied to the fears, which he or she seems to be having in his or her life. The happenings in the film also point out to the viewers that it is very important to be people who live for the moment and enjoy the pleasures which life has to offer. This is a fact, which was highlighted when Max met up with Alison, his high school sweetheart. Initially, it is realized that he had an allergy for strawberries. However, upon their meeting, Alison notes that max is eating strawberries. She questions this and the answer gives is that Max had gotten past his

Capstone Experience (Employee Impact on the Plan )3 Assignment

Capstone Experience (Employee Impact on the Plan )3 - Assignment Example have a negative effect on the organizations performance as a whole. Bad behavior in an organization setting can emanate from the work groups, to which an employee belongs; bad or strict organizational culture and policies e.g. tight supervision; work attitudes; organizational politics e.g. favoritism in promotions, poor compensation policies, personal deviance e.g. verbal abuse, sexual harassment and endangering co-workers, etc. (Robbins and Judge, 2012). Deviant behavior has a negative effect on employee recruitment and training (Martinko, Gundlach and Douglas, 2002). For instance, deviant behavior can lead to favoritism during recruitment, demotivation of new employees, high employee turnover, resistance to change, unhappy workers, unsafe work environment, low employee production, hostile work environment, low-skilled workers due to lack of commitment from old employees to mentor and train new employees, dissatisfaction, etc. (Tina, n.d.). The overall ramifications of poor employee training like poor or low quality work processes can affect negatively on the overall performance of the organization leading to business failure. Therefore, it is imperative that negative behaviors in organizations are checked to ensure that employees are satisfied because the overall performance of the organization depends on the productivity of individual employees of the organization.

The assignment will also identify the legal and regulatory trends that need to be taken into consideration and how the CSA will adapt to changes in the industry. Major issues will be identified and classified to determine the importance of each issue in the analysis. SWOT ANALYSIS: Strength: Weakness Strategy- Provide quality service by staying true to the CSA vision, mission, and core values Structure- The structure for CSA is simplistic that it can be managed by the owner and an Administrative Executive and service rendered by contractors Resources- limited resources are needed for start up (capitol, facilities, computers, personnel Leadership- CSA leadership has a proven track record within the combat sports community Technology- CSA has very little knowledge of current technology application such as web design. Intellectual Property- All applicable regulatory requirements for SCA need to be written. Economic: Combat sports are currently the fastest growing sports in the U. S Technology: The growth in technology allows faster communication via social media, smart phones to allow for real time communication Innovation: By staying up to date on the changes/issues in the sports CSA will can stay of the leading edge of training officials and provide customers will the best service available Competitive Analysis: There is tremendous growth in the sports. There are more promoters than established sanctioning bodies. Resulting in a stronger market share for a reputable sanctioning body Legal/regulatory: Combat Sports legal/regulatory requirements vary from state to State Social: Changes in social values of promoters (ethics/morals) and competitors ( banned substances) require constant supervision Environmental: Exposure to blood borne pathogens by officials, competitors, and fans must be mitigated by ensuring testing and proper disposal of bio hazard materials Opportunity: Threat: The Combat Sports Association SWOT analysis provides key areas of focus for development of a strategic plan for operating a new sanctioning body for combat sports in Nevada. The external factors that will be looked at are legal and regulatory requirements in the combat sports industry and how CSA will apply these requirements to ensure customer compliance. CSA will look at the economical perspective in regards to the growth of combat sports in Nevada and the competitive analysis SCA will use to be a low-cost provider in a competitive market. These issues are classified as the external issues of CSA . The internal factor that will indentify the strengths and weaknesses of CSA will be Leadership, structure, resources, and intellectual property. The leadership provided to CSA customers and sub-contractors is a differentiating value chain activity that sets CSA apart from competitors. CSA is structured as a flat organization to provide a simplistic communication with customers and contractor and eliminate costs to maximize profit. Few physical resources and overhead are needed to develop CSA in the combat sports industry. The most significant hurdle to overcome fro CSA is the development of intellectual property that will set CSA apart from the competition. These issues are classified as the internal issues of CSA. The two largest hurdles for CSA are the legal and regulatory factors (external) and the intellectual property (internal). Legal and regulatory factors were identified as a threat based on governmental laws of the state of Nevada. The Nevada State Athletic Commission (NSAC) is the office of primary responsibility (OPR) that sets the regulatory guidance of combat sports in Nevada. This is accomplished through N. R. S 467 and N. A. C. 467 making compliance mandatory for all sanctioning bodies within Nevadas jurisdiction. CSA must comply with these standards and stay attuned to any changes, adapt to any changes of the law. One example is the policy changes for Therapeutic Use Exemption (TUE) for Testosterone Replacement Therapy (TRT) for combat sports athletes. The intellectual property for the SCA must be written to comply with the regulatory requirements of the NSAC. SCA classified intellectual property as an internal issue and weakness. CSA intellectual property is the policies and procedures that the organization will operate from and the standards operating procedures that its customers/promoters/athletes will abide by. The intellectual property has for CSA has yet to be written. Until the CSAs regulatory guidance is written CSA will be unable to operate within the state of Nevada. The economic factor was classified as an external issue and indentified as strength for CSA. Combat Sports in the U. S. , particularly Mixed Martial Arts (MMA) is the fastest growing sport. With the interest in the sports growing more gyms that cater to the mixed martial artist are opening. Those athletes that wish to compete seek out organizations they wish to compete for. This results in more events being put on by promoters. There is more business minded people investing in becoming promoters. As this growth continues it means more opportunity and work for sanctioning bodies. The CSA can take advantage of this growth in the MMA by conducting a competitive analysis to determine its place in the market. The competitive analysis was classified as strength for CSA because it beat the competition in all but one category. This gives CSA a strong competitive position in the sanctioning body market. Competitive Analysis CSA Rival 1 Rival 2 Quality performance 10 8 7 Reputation/Image 10 7 6 Service Capabilities 10 8 7 Competence Capabilities 9 9 7 Financial Resources 8 9 8 Geographical Infrastructure 9 8 8 Un-weighted Strength Assessment 56 49 43 The leadership of CSA is classified as an internal factor and identified as strength. One of the key factors is the experience the leadership has in the combat sports industry and over 21 years of providing quality control for regulatory standards. CSAs leadership has a proven track record within the industry for adherence to regulatory compliance and leading promoters to compliance rather than forcing them. The leadership is recognized as a subject matter expert within the state for matters concerning combat sports and is often recommended by NSAC to consult with new promoters prior to state licensing. The CSA leadership is a resident of the state of Nevada; where-as rival companies are out of state residents. This allows CSA leadership to frequently meet with NSAC on key issues and provide on-site supervision for customers/promoters event. All the experience and expertise has allowed the CSA leadership to develop a vision, mission, and core values that will allow SCA to achieve unprecedented success in a growing industry. The Structure of SCA flat this allows for direct communication to all functional areas of the CSA. This also is effective in cutting costs. By maintaining a flat structure CSA management speaks directly with customers and subcontractors on all matter to facilitate continuous improve to relationships and processes. For example; if a customers CFO needs a specific information on CSA officials travel itinerary they can call CSA management or the officials directly or if the customers administrative executive needs statistical data from previous event they can call CSA management directly. One of the benefits of a flat structure is that CSA provides customers with a hands-on approach to dealing with the customers needs. This creates a friendly and trusting environment. Another benefit to a flat structure is that it alleviates the high costs of multiple management and employees costs. With a flat structure that outsources key positions to subcontractors CSA can focus directly on maximizing profits. Customers/promoter will pay the subcontractors directly and only pay CSA the event representative fee and the standard sanctioning fee for services rendered. The resources factors was classified as an internal strength because there are very little resources and overhead needed to start up a sanctioning body. Essentially the initial resources needed are a computer, home office, and standard office supply. Very little capitol is needed to start this business. Some additional costs will be a business license, incorporation fees, legal fees to ensure contracts with customers are properly written to reduce CSA liabilities. CSA has established relationships with the best subcontractor/officials (Referees, judges, timekeepers, scorekeepers, inspectors, and physicians) in the combat sports industry. These relationships will help CSA move forward to become the premiere sanctioning body in Nevada. By using qualified and training officials CSA will create a culture of safe and fair competition for its customers that will attract the best competitors. This will result in a larger fan base for the promoters thus generating higher ticket sales and increased revenue. The comprehensive SWOT analysis conducted by CSA has achieved compound result that provides CSA with multiple areas of focus. It identified the internal strength and weaknesses of the organization. The opportunity and threat identified external factor that need to be focused on. The competitive analysis provided a current snapshot of how CSA currently ranks within the industry. The SWOT analysis also shows CSA where it can make improvements. The overall assessment for CSA is that it can gain a considerable market share of the combat sports industry within Nevada considering the growth of combat sports.

Organizational Structures that are Suitable in the Business Circumstances Today :: Papers

Organizational Structures that are Suitable in the Business Circumstances Today The world today is experiencing the most rapid pace of change in its history. The purpose of this essay is to discuss what organizational structure is suitable in the business circumstances of today. This essay will argue that ‘the environment of the 21st century is such, that to be effective, organizations are tending towards less formalized structures than used in the past’. To support this argument, firstly organizations will be defined, and then the properties that make an organization effective will be identified. Next organizational structure will be appraised, and what constitutes business environment will be established. Finally the influences globalisation and technology have had on the will be addressed in relation to changes in organizational structure. Robbins et al. define an organization as ‘a deliberate arrangement of people to accomplish some specific purpose’ (2000: 5). While Wood et al. consider organizations as ‘collections of people working together in divisions of labour to achieve a common purpose’ (1998: 15). These definitions fits a wide variety of groups such as sporting clubs, religious bodies, voluntary associations etcetera however for this essay will concentrate on business organizations. A Business organizations’ purpose is to deliver and product or service in such a way that a benefit is gained for the organization, profit or goodwill for example. The Macquarie dictionary is defines effective as ‘producing the intended or expected result and producing a striking impression’ (1990). Thus an effective organization is an arrangement of people that successfully achieved their purpose, ie. a large profit of fine product, and have done so in a noteworthy, exemplary, commendable method or fashion. It is understood that to be effective an organization must be efficient. Efficiency is defined as ‘the relationship between inputs and outputs, the goal of which is to minimize resource cost’ (Robbins et al., 2000: 8). Usually a business organizations’ success is primarily measured in financial profit, though this is not the only benchmark. Organizational structure is defined as ‘the organization’s formal framework by which job tasks are divided, grouped and coordinated’ (Robbins et al., 2000: 351). Generally an organizations’ structure is considered to be the managerial framework that directs the non-managerial employees. Traditionally western organizational structure can be argued to have developed from the feudal system of government where a strict pyramidal power and class structure existed.

Contract and Invitation

1. Offer 1. Offer means a proposal by a person in which he makes his willingness to enter into a legally binding contract for some conside ¬ration. 2. An offer is made with the object of getting consent of the offeree. 3. An offer can be accepted by the offeree. 4. An offer when accepted becomes an agreement. Invitation to Offer 1. An Invitation to offer means an intention of a person to invite others with a view to enter into an agreement. 2. An invitation to offer on the other hand is made with . An invitation to offer cannot be accepted by the person to whom it is made. 4. An invitation to offer cannot be accepted at all. 2. An offer / proposal are necessarily for the formation of an agreement. Section 2(a) of Contracts Act 1950 said when person signifies to another his willingness to do / to abstain from doing anything, with a view to obtaining the assent of that other to act / abstinence, he is said to make a proposal and invitation to treat means an invitation to make an offe r.A) There are many distinguishing between offer and invitation to treat. The first distinguishing is from meanings. Offer is an expression of willingness to contract on certain terms made with the intention that it shall become binding as soon as it is accepted by the person to whom it is addressed, the offeree. Invitation to treat different with offer it means an invitation to make an offer. An invitation to treat is not an offer, but an indication of a person's willingness to negotiate a contract.Based on the case: COELHO v. THE PUBLIC SERVICES COMMISSION[1964] M. L. J. 12 In this case, the applicant, a Health Inspector under the Town Board, Tanjong Malim, applied for the post of Assistant Passport Officer in the Federation of Malaya Government Oversea Missions advertised in the Malay Mail dated 19 February 1957. Consequently, the applicant was informed that he was accepted and, after undergoing training, he was posted to the Immigration Office,Kuala Lumpur, where he remained unt il December 1958 when he was transferred to the Immigration Office at Johor Bahru. On 5 November 1959, the Secretary to the Public Services Commission in a letter addressed to the applicant as ‘Assistant Passport Officer on Probation' informed him that, following a report from the Controller of Immigration concerning his conduct in the irregular issue of certain passports, disciplinary action was being taken against him with a view to his dismissal.The applicant made representation as invited by the said letter and, on 24 December 1959, the applicant was informed that the respondent had decided that he should not be dismissed but that his appointment on probation be terminated forthwith by payment of one month's salary in lieu of notice. The applicant now moved the court for an order of certiorari to quash the decision of the respondents on the grounds of error in law, want of jurisdiction, and failure to observe the principles of natural justice. An order of certiorari is an order of the court directing that something be done; in this case, the court order applied for was one directing that the decision of the respondents be overturned). It was held that: 1. That the Malay Mail advertisement was an invitation to qualified persons to apply and the resulting applications were offers. 2. The information conveyed to the applicant was an unqualified acceptance to join the overseas mission and he so understood it.B) Second distinction between offer and invitation to treat is an offer maybe made orally in writing or by conduct such as example of an offer made by conduct is where a customer in a supermarket chooses goods and hands them to the cashier, who then accepts the customer's offer to buy. Invitation to treat may made by displaying goods in shop windows, on shelves, advertisement, tender / auction or a statement of price. Based on the case of: PHARMACEUTICAL SOCIETY OF GREAT BRITAIN v. BOOTS CASH CHEMIST LTD[1953] 1 A11 ER 482. In this case the Defendant was being charged for failing to comply with one of the Great Britain Laws, i. . The Pharmacy and Poisons Act, 1933 which stated that it was illegal to sell specified poisons without under supervision by registered pharmacist. The Defendant operated self-service shop where a customer may select any goods, which were being display in the shop. When the customer has picked the goods, after that, the payment was to be made at the cashier's desk. At the cashier's desk, the operator of the shop can't stop the transaction since the display of goods as regarded as proposal and when the customer picked the goods as regarded as acceptance, therefore, the self-service shop failed to comply the above-said law.The self-service shop operated according to the above-said law display of goods only be regarded as invitation to treat and the customer was the one who made the proposal. Later on, at the cashier's desk a registered pharmacist supervised the transaction and was given authority to refuse the contract of sale, if violated any provisions in the above-said law. It was held that the Defendant was not made an illegal sale since display of goods only be regarded as invitation to treat and the customer was the one who made the proposal.Later on, at the cashier's desk a registered pharmacist supervised the transaction and was given authority to refuse the contract of sale, if violated any provisions in the above-said law. C) Another is an offer have a termination. There is based on counter-proposal, by using notice of revocation, lapse of time, by failure of acceptor to fulfill a condition precedent to acceptance and by the death of mental disorder of the proposer. For an invitation to treat there is no circumstances or conditions to termination a proposal. The termination of proposal is based on cased:MACON WORKS AND TRADING SDN BHD v. PHANG HON CHIN & ANOR[1976] 2 M. L. J. 177. In this case, the defendants gave an option to A her nominees to purchase a piece of land. The option was exercisable only after one LK showed no more interest in the land. The plaintiff's, A's nominee, exercised the option and claimed specific performance. The defendant resisted, contending inter alia, that the offer had already lapsed. It was held that where no time was fixed, an offer would lapse after the expiration of a reasonable time (section 47 of the Contracts Act 1950).What is reasonable is a question of fact depending on the actual circumstances of each case and the nature of the business. Failure to accept within a reasonable time implies rejection by the offeree. D) Otherwise, an invitation to treat is an action inviting other parties to make an offer to form a contract and it just a first step to negotiate, or indication of a person's willingness to negotiate a contract but an offer is a creates a binding contract, subject to compliance with the terms of the offer. It refers to the case:M & J FROZEN FOOD SDN. BHD & ANOR v. SILAND SDN BHD & ANOR[1994] 1 M. L. J. 303. In this case that Siland Sdn. Bhd (the first respondent) was the registered owner of a piece of land which it charged to the second appellant, Eu Finance Bhd. Due to a default on the part of the first respondent, the second appellant applied to the senior assistant registrar (the SAR) and obtained an order for sale of the property by public auction. M & J Frozen Food (the first appellant) was the highest bidder and was pronounced the purchaser of the property.The first appellant paid a 25% deposit of the total purchase price as provided under the conditions of sale, while the balance of purchase money was to be paid into court within 30 days from the date of sale. However, this was not done. It was held that the provisions of the National Land Code 1965 showed that the sale at this juncture (at the fall of hammer) had only be concluded in the sense that the goods would no longer be offered for a sale to prospective buyers and the successful bidder could not be permitted to ret ract his acceptance.Thereafter, each party to the contract of sale must perform his part of the obligation and until then no executed or actual sale had been concluded. Therefore a reference to a sale being concluded at the fall of the auctioneer's hammer could only refer to that stage of the transaction of sale when there was concluded an agreement between the vendor and the highest bidder, the former to sell and the latter to purchase the goods. E) In addition, statement of price is not necessarily an offer because offer only has a termination on proposal between invitations to treat; statement of price is necessarily in an invitation to treat.It referred to the case of: HARVEY v. FACEY[1893] AC 552. In the case that the plaintiff telegraphed to the defendant, ‘Will you sell us Bumper Hall Pen? ‘ ‘Telegraph lowest cash price'. Defendant telegraphed in reply ‘Lowest price for Bumper Hall Pen $900. The plaintiff then replied ‘We agree to buy Bumper Hall Pen for $900 asked by you. Please send your title deeds. No reply from the defendant. Plaintiff claimed that there was a contract between himself and the defendant. It was held that there was no contract. The second telegram was not an offer but in the nature of an invitation to treat.The final message could not be looked upon as an acceptance. F) Offer involved one party (unilateral) or more parties (bilateral). Bilateral contract is an agreement in which each of the parties to the contract make a promise or promise to the specific person and public at large. On the invitation to treat it only involve to the one party (unilateral). It means that only one party, make an offer but it depends to a person to form a contract. It based on case of: CARLILL v. CARBOLIC SMOKE BALL CO. LTD[1893] 1 QB 256.Facts of the case that the defendant made an advertisement in the newspaper where the defendant willing to pay 100. 00 Pounds to anyone who still suffering influenza after taking the medici ne according to the prescription sold by the defendant. On top that the defendant has deposited 1000. 00 Pounds in the special account in the Alliance Bank for the above-mentioned purposes. The plaintiff used the above-said medicine, unfortunately, she still suffering the influenza. Then, the plaintiff asked for the compensation that had been promised by the defendant in the newspaper.It was held that the plaintiff was entitled for the promise that amount 100. 00 Pounds made by the defendant since the defendant's advertisement being considered as proposal addressed to public at large and the plaintiff has accepted the proposal by purchased the medicine and used the medicine according to prescription. The defendant advertisement being considered as proposal because in the advertisement there was an element of willingness where the defendant has deposited money that amount 1000. 00 Pounds in special account in the Alliance Bank for the above said purposes.G) The offer must be communic ated to the offeree if the offeror want to revoke his or her proposal before it can be accepted and the offeror will bind to a legal after the acceptance but invitation to treat there is does not communicated before the acceptance and the invitation to treat can revoke anytime without mention to another party. It based on cased: BANQUE PARIBAS v. CITIBANK NA[1989] 1 M. L. J. 329, CA. In this case, a company, Selco Salvage Ltd, wrote a letter dated 14 October 1985, offering to sell to the respondents the salvage claims in respect of nine vessels.By a letter dated 31 October 1985, Selco offered to sell to the appellants salvage claims in respects of five vessels which were also part of the nine salvage claims offered for a sale in their 14 October 1985 letter to the respondents. The appellants accepted the offer and purchased those five salvage claims. Subsequently, on 7 November 1985, Selco again wrote to the respondents offering to sell their salvage claims in respect of four vessel s which were listed in the 14 October 1985 letter.They further stated in their letter that ‘ this letter will supersede our previous letter dated 14 October 1985'. The respondents accepted the offer and purchased the salvage claims regarding these four vessels. A dispute arose between the appellants and the respondents as to the ownership in respect of the five salvage claims and the respondents claimed that on 20 November 1985, they had purchased the five salvage claims without any notice of the appellant's prior purchase of them from Selco.The respondents agreed that although they purchased the salvage claims of four vessels on 7 November 1985, Selco's offer to sell the balance five salvage claims contained in the 14 October 1985 letter still remained open and available for acceptance by them, and that they finally accepted the offer on 20 November 1985. It was held that the 7 November 1985 letter written by Selco to the respondents contained the vital paragraph namely, â₠¬Ëœthis letter will supersede our previous letter dated 14 October 1985'.The only meaning one can give to this paragraph is that the 14 October letter had been replaced or substituted by the 7 November letter. The effect of that is any offer contained in the 14 October letter which had not been accepted had been withdrawn. Selco had, on 7 November 1985, in clear and unequivocal terms, withdrawn or cancelled the offer contained in the 14 October letter and henceforth there was no offer which remained upon and available for acceptance by the respondents on 20 November 1985 or any other date.Where the communication of acceptance is made by the acceptor through a course of transmission such as post, telegraph, telegram, then the communication of the acceptance is deemed complete as against the proposer, when it is put into a course of transmission to him, so as to be out the power of the acceptor.

As per the Halsbury's Laws of England. an offer is an expression by one person or group of persons, or by agents on his behalf, ade to another, of his willingness to be bound to a contract with that other on terms either certain or capable of being rendered certain. [Halsbury's Laws of England- Para. 632] An invitation to offer, on the other hand, may also be called an invitation to treat (as it is, under English Law) and merely indicates the interest of one party to enter into negotiations and is by no means supposed to form a binding contract. [Halsbury's Laws of England- Para. 633 4. Difference between AN OFFER and an INVITATION TO TREATAn invitation to treat is to be distinguished from an offer as it merely indicates a willingness to deal but does not display an intention to be bound. Broadly speaking, an invitation to treat is an action by one party which may appear to be a contractual offer but which is actually inviting others to make an offer whilst an offe r is an expression of willingness to contract on certain terms, made with the intention that it shall become binding as soon as it is accepted by the person to whom it is addressed, the â€Å"offeree†.The indication of willingness to enter into a contract may manifest itself in a variety of ways. The indication can be contained in a letter, a newspaper, a faxed document, an e-mail or it may even be inferred from someone’s behavior. An offer is something which must be done or refrained from being done which is accepted to become a contract. For example, you offer your car for sale for a price say for $9,000. 00, your offer to the world at large is $9,000. 0 consideration for your car. Your term is simply if you give me $9,000. 00 you can have my car. An invitation to treat simply means an invitation to make offers, so using the example above; if instead of the price you just said – â€Å"offers considered† that become an invitation to treat, then you are i n a position to accept or reject offers. It is important to distinguish between an offer and an invitation to treat.

Wearable Computer

Ever since the development of the ENIGMA (the first digital computer), computers have inspired our imagination. In this period came the World War II code breaking machine designed by Alan Turing, and Von Neuman’s ENIAC which can be called dinosaurs compared to present day PCs. In the earlier days, computers were so huge that it took an entire building, or at least a floor to occupy one. Computers of that era were very slow by today’s standards.In the non-ending struggle to increase computing speed, it was found out that speed of electricity might become a limiting factor in the speed of computation, and so it was a need to lessen the distance that electricity had to travel in order to increase the computing speed. This idea still holds true in modern computing. By the 1970s, computers grew fast enough to process an average user’s applications. But, they continued to occupy considerable amount of space as they were made of solid blocks of iron.The input was done b y means of punch cards, and later came the keyboard, which revolutionalized the market. In 1971 came the 4004, a computer that was finally small in size. The programmability of these systems were quite less. Still, computers had to be plugged directly in to AC outlets, and input and output done by punch cards. These computers were not built keeping users in mind. In fact, the user had to adjust himself with the computer. This was the time when wearable computer (wearcomp) was born.In the 1970s, wearcomp challenged the other PCs with its capability to run on batteries. Wearcomps were a new vision of how computing should be done. Wearable computing showed that man and machine were no more separate concepts, but rather a symbiosis. The wearcomps could become a true extension of one’s mind and body. 1. 1. Definition of â€Å"Wearable Computer† Wearable computing facilitates a new form of human-computer interaction comprising a small body-worn computer that is always on and always ready and accessible.In this regard, the new computational framework differs from that of hand held devices, laptop computers and personal digital assistants (PDAs). The â€Å"always ready† capability leads to a new form of synergy between human and computer, characterized by long-term adaptation through constancy of user-interface. 1. 2. What is a Wearable Computer? A wearable computer is a computer that is engulfed into the personal space of a user, controlled by the user, and has both operational and interact ional constancy.Most notably, it is a device that is always with the user, and into which the user can always enter commands, and execute a set of such entered commands, and in which the user can do so while walking around or doing other activities. i. e. The wearcomp is a intertwined computer. Unlike wristwatches, regular eyeglasses, wearable radios, etc. the wearcomps are reconfigurable as the regular desktop PCs. Wearable computing can be defined in terms o f its three basic modes of operation and its six fundamental attributes.

Bushs Cold War essays

Bush's Cold War essays For fifty years, the total purpose of American foreign interaction was to stop the spread of Communism. Only the threat of annihilation could prevent the citizens from rolling back into their traditional isolationism. George Washington himself preached that the United States should stay out of European affairs, and his people didnt forget that. Keeping their noses out of Europeans business was like second nature. Unfortunately, the Cold War changed that. If the US wanted to keep its allies democratic, or at least dictatorial, it would have to give them a reason to stay that way. In Eastern Europe, countries were given money and other supplies to keep themselves out of poverty. Impoverished people tend to turn towards Communism. In South America, harsh dictators were supported only because a dictator is not going to let his people turn against him. For the longest time, this plan worked. However, fifty years is a long time. By the time the USSR broke up in 1991, the American people were used to meddling in foreign affairs. Sitting back and funding internal improvements and the economy no longer appealed to the Great Society. As a consequence, the old President Bush defended Kuwait from Iraq, not so much that it was necessary for the United States, but because it seemed right and just. This policy has been imitated in Bosnia, Kosovo, and partially in Iraq (after no Weapons of Mass Destruction were found, Bush tried to turn this into a war to save the Iraqi people). This is not a good trend. If the US continues to meddle in other peoples business, it will make some powerful enemies. The United Nations has already been deeply offended when Bush ignored its demand not to invade Iraq. Being the largest cooperation of democratic nations in the world, the UN is not a group to infuriate. If the European Union decides to shun the US, a crippling amou ...

Organizational Behavior Case Study Example | Topics and Well Written Essays - 1000 words - 1

Organizational Behavior - Case Study Example Indeed, all the medical staff report to the Chief Medical Officer and clinic administrator. Notably, all the medical staff and the management must have adequate training and knowledge on their responsibilities (Borkowski, 2011). As such, they performed according to their abilities and valued team work in achieving the goals of the clinic. However, late last year, the Chief Medical Officer and clinic administrator decided to implement changes in the clinic’s policies and practices without consulting the medical staff which led to adverse effects in the organization (Borkowski, 2011). At the time, there were numerous delays and long wait list in the clinic subject to increasing number of patients, frequent problems with the machines in the theater, lack of administrative support, few numbers of medical staff, inefficient policies, poor IT support, and lack of space in the clinic as earlier noted by the medical staff. The Chief Medical Officer and clinic administrator opted to in crease the working hours of the medical staff, introduce a universal method to assess the performance of the health providers, and changed policies as they sought to address the problems at the clinic. Notably, the new working schedule did not solve the problems as the medical staff would work for long hours for no extra returns thus demotivating them. Moreover, the new policies contradicted with the professional ethics of the medical staff and thus they declined to adopt the new policies. In fact the management set the working in the clinic to be from 7:00-5:30 every day including weekends where every medical staff would work for atleast70 hours in a week. More so, the management used an informal method to communicate the changes to the medical staff. As a result, lack of administrative support, communication, and motivation led to resignation of 2 nurses and 2 physicians thus crippling the operations of the facility. However, the clinic is slowly restoring its operations and effic iency after the clinic was put under new management. X And Y-Theories Styles of Management Douglas McGregor devised Theory X and Theory Y of management which assumes human nature and human behavior in management (Kopelman et al, 2008). Theory X assumes that work is undesirable, works avoid responsibility, money is the ultimate motivation to work, and creativity is exclusive to  management (Mohamed & Mohamad, 2013). The theory asserts that workers require forcible manipulation, resists change, control, and direction for them to achieve company objectives and workers avoid work at all costs. In this style of management, there is minimal delegation, centralized control and supervision (Mohamed & Mohamad, 2013). Indeed, the X-Theory assumes that the management’s role is to coerce and control employees. This theory applies in large organizations where X-Theory management is unavoidable (Mohamed & Mohamad, 2013). On the other hand, we have the Y-Theory which assumes a positive vi ew of human behavior where individuals are normally responsible, industrious, creative, and adopt self-control in their work (Mohamed & Mohamad, 2013). Indeed, this theory would have helped with provider retention in this case study. This is because theory Y encourages participative management where the management consults with the employees in making decisions and affords employees with a chance to control their working environment (Mohamed & Mo

Discovery and settlement of the new world Coursework

Discovery and settlement of the new world - Coursework Example Their occupation mainly consisted of hunting and farming in a limited manner as the invention of tools and wheel were not made in those times. However, they used few primitive tool and gold and silver for ornaments. None of the tribes had written language. They used pictures to convey their messages or make a record of important events and for long distance messages, used smoke signals and sign language. On the other hand, the tribes in south like Aztec and Inca were more developed and furnished with equipment formed a cultured society. They were at an advance level in mathematics and architecture, due to which proper cities and towns were constructed and great stone temples were made to worship. They had a written language. A common viewpoint about these southern tribes is they had a high level of cultural advancement comparatively to any country of the Western Europe. The disagreement in Anglican Church found its way across Atlantic oceans. The puritans especially were in tolerant about beliefs different than them. They argued that the religious practices of Church of England should not resemble to Catholicism. The aim of British Colonies was to practice religion as to worship God with freedom. However, this approach was only adapted by early colonists, which was not extended further. There were four main New England colonies, Massachusetts, Rhode Island, Connecticut, and New Hampshire. Later on the survival of English colonies depended on them In 1629, Massachusetts was founded by few puritans of common faith. About one thousand men, women and children started their journey towards America, as they were distressed to see the moral life and future of religion in England. They came to America to practice religion freely and in turn forced the residents to practice the same belief. They punished, whipped and persecuted those who did not belief in puritan faith. Many settlers were forced out from their lands for not practicing those beliefs, which eventually set tled in Rhode Island. In 1644, Roger Williams was banished from the Massachusetts colony due to his belief in, God can be worshipped in many ways. He did not thrust puritan believes on the Indian tribes due to which he was ordered to ship back England but he managed to escape and found Rhode Island, which was the first colony where any or every religion was acceptable to practice. The dissenters were forced to live here and some later on moved to Connecticut. Thomas hooker was the most popular Puritan preacher in the Massachusetts colony, who formed Connecticut colony in the valley of Connecticut river .He angrily fought for religious rights and in 1662 was granted with the charter by the Anglican Church. A written plan was documented for the four colonies and presented to the government by Connecticut. The first big battle among settlers and Native Americans was also fought here and was won bye English settlers. New hemisphere was founded in 1679 with the consent of English King an d it became a royal colony. At one time it was part of Massachusetts. The immigration of tribes, from a nonjudgmental perspective was held acutely. Past events flowed in front our eyes as a story being told. The determination and efforts put by daring explorers who ventured over the world and discovered new lands and exotic things, is a note to be marveled upon. With few sources in hand and limited knowledge about the whereabouts of final destiny these explorers are

Reflect on a challenge you overcame through persistence (650 words) Essay

Reflect on a challenge you overcame through persistence (650 words) - Essay Example I read the speeches of Socrates when I entered my tenth grade. It was then that i realized that I wanted to attain a speech ability like his through which i could persuade people as to what life really is about. In the tenth grade i tried competing in the debates organized by my school but i was not encouraged a bit by my parents or teachers. When i gave the auditions of my debate for the first time in school not a single stone was unturned in humiliating me by my class mates. It was then that i was quite discouraged and went into isolation for a few days to think as to if i could achieve my goal or not. However i did not lose hope and worked on my abilities to deliver speech. My aim was to participate in the debate competition as a leading participant but this aim was laughed upon by many of my class mates. In order to grasp better skills i had to sort out certain things which i lacked when delivering speeches. I suffered from the problem of stage fear and i had to cut off this prob lem first in order to deliver the speeches. To rectify this problem i started participating in activities which had audiences viewing it. The first option was of selecting different sports and participating in different activities so i could get strong in front of the audience. This greatly helped me in the field of debates as i learned to act in certain situations. After that my very next aim was to work on my debating skills. I began reading books and increased my vocabulary so i could write a better speech which would attract the audience. I learned the basics of debating through different lessons and i was successfully able to craft speeches. I delivered my speech in front of my friends and some of them praised it. This gave a boost to me so that i could compete in the next competition. I also got the encouragement of my parents and teachers after i rehearsed in front of them. I polished my skills of debating since i passed my tenth grade and was able to deliver in my next try. It was in high school that i tried for competing in debating again and this time the try was not wasted. I received a better appreciation from the crowd but still could not make up to the final participants. I erased my stage fear and learned to act in the situations of debates. It was here that the changing point of life had arrived. The teachers realized the potential in me and gave me a chance again in the last year of my high school. I learned skills from them and delivered well in the auditions. I was then qualified finally for the participants sent through my school. Although this was my first exposure to debates nationally i learned a lot from the event. I did not get to win from the event but my goal of being a debater was fulfilled. It was then that i made a platform for me to be a debater. After I passed my high school i participated in events which were outside the territory of my school and learned a lot. I have since become a debater with the right potential. My aim of becoming a debater only became successful after I went through a lot in my life. Persistence as said by Edison was the major source of success in my life. I have learned a lot through my experience and can now successfully achieve many of the aims that i had in

Social entrepreneurship Essay Example | Topics and Well Written Essays - 1000 words

Social entrepreneurship - Essay Example While this aspect may seem obvious, the distinction interests me deeply because of social entrepreneurship’s potential to produce breakthrough outputs that could solve the perennial social problems such as income disparity, monopolies and so on. We should remember that we have been under some economic systems but our world is still confronted with issues such poverty, exploitation and so forth. In the course of my studies and research in this field, I have come across a lot of business models that sought to define what constitutes business and its purpose. There has been some degree of confusion for me since it seemed logical and reasonable to follow the popular economic theories, such as those of Milton Friedman’s which place profit as the main objective of a business’ existence. This was where things got interesting because the concept of the social entrepreneur disproved some widely accepted notions, say, in terms of the stakeholders in an enterprise. For the traditional business people, the sole stakeholder in a business organization is the stockholder or the owner of the capital and that the management is working for his benefit. In social entrepreneurship, the stakeholder is not only the entrepreneur but they include the community, the employees, their clients and all the participants in the organization and its operation. The attributes cited by William Drayton, which differentiates an entrepreneur from the social entrepreneur further underscores my point: â€Å"Social entrepreneurs have the same core temperament as their industry-creating, business entrepreneur peers but instead, use their talents to solve social problems.† (Drayton, 2002) If this concept would be refined into a successful business model and integrated in the mainstream, then there is a chance of a radical positive change not just in business but in the society as well. In line with the previously mentioned â€Å"pearl† the second important point that I would like to discuss

Anomalous Resistance Behavior in Bilayer Graphene

Anomalous Resistance Behavior in Bilayer Graphene Observation of Anomalous Resistance Behavior in Bilayer Graphene Yanping Liu 1,2, Wen Siang Lew 2,*and Zongwen Liu 3,* Abstract Our measurement results have shown that bilayer graphene exhibits an unexpected sharp transition of the resistance value in the temperature region 200~250K. We argue that this behavior originates from the interlayer ripple scattering effect between the top and bottom ripple graphene layer. The inter-scattering can mimic the Coulomb scattering, but is strongly dependent on temperature. The observed behavior is consistent with the theoretical prediction that charged impurities are the dominant scatters in bilayer graphene. The resistance increase with increasing perpendicular magnetic field strongly supports the postulate that magnetic field induces an excitonic gap in bilayer graphene. Our results reveal that the relative change of resistance induced by magnetic field in the bilayer graphene shows an anomalous thermally activated property. ______________________________________ Introduction: The electronic properties of monolayer graphene have been extensively studied due to its intriguing energy band structure with linear dispersion around the Dirac point and chirality exhibiting Berry phase of [1]. There is a zero-energy Landau level (LL) with four-fold degeneracy due to interactions between electron spins and valleys in the magnetic field [2-4]. Recently, bilayer graphene became a subject of intense research due to the low energy Hamiltonian of chiral quasiparticles and a Berry phase of [5-8]. It has a double-degeneracy zero-energy Landau level that incorporates two different orbital states with the same energy under an external magnetic field. The bilayer graphene with a Bernal (A-B) configuration loses some features of monolayer graphene and has a unique band structure where the conduction and valence bands are in contact with a nearly quadratic dispersion [5]. In bilayer graphene, a parabolic band structure ( ) with an effective mass m*=0.037, has been calculated by using the interlayer coupling model [9-14]. What makes bilayer graphene an interesting material for study is that the interlayer potential asymmetry can be controlled by an electric field, thus opening an energy gap between the conduction and valence bands [16-18]. Various applications for bilayer graphene are possible due to the fact that its band gap can be modulated by using an external out-of-plane electric field and chemical doping. There is intensive research on bilayer graphene under the application of a perpendicular electric field, however, experimental reports on magnetic transport properties of bilayer graphene are not as well-studied. Recent theoretical work reports on excitonic condensation and quantum Hall ferromagnetism in bilayer graphene [22]. There are interesting features in bilayer graphene due to its extra twofold orbital degeneracy in the LL spectrum, which results in an eightfold -degenerate LL at zero energy. The scattering mechanism of graphene is current ly a subject of intense research and debate. The problem of magneto-transport properties in the presence of Coulomb impurities is still an open research problem. Our understanding of the nature of the disorder and how the mesoscopic ripple effect affects the transport properties still need improvement; hence, a better understanding on the general electric and magnetic transport properties of bilayer graphene is necessary. In this paper, we have systematically investigated the charge transport properties in bilayer graphene as a function of temperature, magnetic field, and electric field. Our measurement results have shown that bilayer graphene exhibits a semi-metallic R-T property and an unexpected sharp transition of the resistance value in the temperature region 200~250K. The longitudinal resistance decreases with increasing temperature and electric field, a behavior that is markedly different from the experimental reports of monolayer graphene. Our results reveal that the energy gap in the bilayer graphene shows an anomalous thermally activated property and increases with. We have shown that this phenomenon originates from a tuneable band structure behavior that can be controlled by a magnetic field, a property that had never previously been observed in bilayer graphene. It has been shown that Raman spectroscopy is a reliable, non-destructive tool for identifying the number of graphene layers and it can be done through the 2D-band deconvolution procedure [23-25]. The Raman spectra of our graphene structure were measured at room temperature using a WITEC CRM200 instrument at 532 nm excitation wavelength in the backscattering configuration [26-28]. Fig.1a shows the characteristic Raman spectrum with a clearly distinguishable G peak and 2D band. The two most intense features are the G peak and the 2D band which is sensitive to the number of layers of graphene. The position of the G peak and the shape of the 2D band confirm the number of layers of graphene. Additionally, the number of layers of graphene can be easily distinguished from the full width half maximum of the 2D band, as its mode changes from a narrow and symmetric feature for monolayer graphene to an asymmetric distribution on the high-energy side for bilayer graphene [27]. The 2D band inset in Fig.1a shows that the Raman spectrum of bilayer graphene is red-shifted and broadened with respect to that of the monolayer graphene. Fig. 1b shows the four terminal resistance as a function of carrier-density n, and the sample shows a pronounced peak at density . Note that the sharp peak in resistance at low n is enhanced by the opening of the small energy gap owing to disorder-induced differences in carrier density between the top and the bottom layers of the flake. We have characterized the current (I)-voltage (V) characteristics of the bilayer graphene via four-terminal measurement, at different temperatures and magnetic fields. Shown in Fig. 2a are the I-V curves for bilayer graphene under the application of various magnetic fields at three different temperatures: 2 K, 200 K and 340 K. The magnetic field is applied in the perpendicular direction to the plane of the graphene. For all the temperatures and magnetic field strengths, the bilayer graphene exhibits a linear I-V curve. This implies that the graphene layer is ohmic in nature. We observed that for a fixed magnetic field, the I-V curve displays a larger gradient at higher temperature than at lower temperature. Interestingly, the gradient of the I-V curve decreases with increasing magnetic field. In our structure, the gradient of the curve corresponds to the conductivity of the graphene layer. Such temperature and magnetic field dependent behaviour of conductivity is characteristic of an intrinsic semiconductor. The decrease in the conductivity of the bilayer graphene with increasing magnetic field is attributed to the excitonic energy gap induced by the magnetic field. This conductivity dependence on the magnetic field suggests that the resistance () of graphene is a qualitative fingerprint of its band gap. In the absence of a magnetic field, the band structure of the bilayer graphene at the Dirac valley has a parabolic dispersion relation. When a magnetic field is present, the band structure is changed to a split Landau level structure [19-21]. Fig. 2(b) is an illustration of the bilayer bandgap and Landau level splitting under the influence of a magnetic field. Inset shows an optical image of the bilayer graphene with the metal contact electrodes. In Fig.2(c) we plot the resistance of the bilayer graphene, as extracted from the I-V curve, as a function of magnetic field for three different temperatures. As the magnetic field was increased in a step of 4T, the resistance increase for each step was different, resulting in a non-linear relationship between the resistance and magnetic field. Interestingly, the observed non-line relationship is markedly different from Zeeman spin-splitting theoretical model with the line relationship, where gap with a free-electron g-factor g=2, where is the Bohr magneton. This potentially indicates sublattice symmetry breaking and gap formation due to many-body correction in this LL [32-34]. This is further confirmation that magnetic field opens an excitonic gap in the bilayer graphene. The temperature dependence of monolayer graphene resistance is mainly attributed to the different scattering mechanisms: Coulomb scattering [35-36], short range scattering [37], and phonon scattering [38-39]. However, the temperature dependence of bilayer graphene resistance has not been established yet. Shown in Fig.3a are the temperature dependence of the resistance of the bilayer graphene under the application of a magnetic field 0T and 12T, respectively. The results show that the resistance of the bilayer graphene drops following non-metallic behaviour as temperature increases from 2K to 340 K. This implies that the bilayer graphene resistors have intrinsic semiconductor properties as mentioned earlier. This can be explained by the decrease in Coulomb scattering with temperature for bilayer graphene due to its parabolic band structure. For B=12T, a similar trend as B=0T is obtained in Fig 3a, where the resistance decreases with increasing temperature. However, the resistance for the entire temperature range is much larger than for B=0T. This indicates that the magnetic field opens an excitonic gap in the bilayer graphene that is thermally activated due to the Coulomb interaction ion-driven electronic instabilities [20, 31]. Ripples are a common feature of cleaved graphene because it is never atomically flat, as it is placed on a substrate such as SiO2 in the term of nanometre-scale deformations or ripples [40-42]. Despite the magnitude of the ripples being quite small, it is still believed to be responsible for the unusual transport behaviour of graphene, also susceptible to adsorbed impurities, defects and the roughness of the underlying substrate [40-43]. On the other hand, it has been shown that suspended graphene films are corrugated on a mesoscopic scale, with out-of-plane deformations up to 1 nm [44-45]. The deformation is a typically smaller than the Fermi wavelengthand these ripples induce predominantly short-range scattering. The observed height variation shows that the surface roughness beyond the atomic-level is intrinsically present in bilayer graphene. Hence, one of the interesting features of corrugation of graphene is that it offers a new experimental opportunity to study how the corrugat ion-induced scattering impacts the transport properties of graphene. It is important to mention that there is a strange sharp threshold like decrease in resistance observed above 200K. The strong temperature dependence is inconsistent with scattering by acoustic phonons. One possible explanation is that the flexural phonons confined within ripples between the top and bottom layer causes the scattering. The presence of the ripple effect exhibits local out-of-plane ripples [44]. Theoretical calculations[41,46] show that the scattering rates for interripple flexural phonons with respect to two-phonon scattering process as, where is the flexural-phonon frequency, the derivative of the nearest-neighbour hopping integral with respect to deformation, a the lattice constant, , and the mass of carbon atom [46]. For low temperatures T () , few flexural modes can be excited inside ripples (). The conductivity of the surface roughness model at the limit at low temperature is[45-46]. As the t emperature increases and typical wavelengths become shorter, short-range scattering excites the flexural phonons. For the high temperature limit, based on the above expression, we can estimate that , which yields ~100 to 1000 at T=300K. The model of quenched-ripple disorder [46] suggested that the electron scattering of the static ripples quenched from the flexural phonon disorder can mimic Coulomb scattering when at room temperature. One should also note that the model predicts stronger temperature dependence (above a certain quenching temperature of about 100K) which is close to our experimental result at about 200K. However, the ripple effect normally leads to a rapid increase in the R-T curve rather than the sudden decrease in R-T as observed for our bilayer graphene. In the absence of a theory to explain the stronger temperature dependence behaviour, we propose that the behaviour is consistent with the ripple effect interlayer scattering instead of interlayer scattering. Fig. 3b shows the schematically illustration of scattering mechanisms in bilayer graphene. For a bilayer graphene, the interlayer scattering between the top and bottom ripple graphene layer is similar to coulomb scattering with stronger dependence on temperature. The rapid decrease in R-T above 200K can be attributed to the transition between the low- and high-T limits in the interlayer ripple effect scattering. On the other hand, it was suggested that the observed strong T dependence could be explained by thermally excited surface polar phonons of the SiO2 substrate [35-38]. The SiO2 optical phonons at the substrate-graphene interface induce an electric field which couples to the carriers in graphene due to it modulating the polarizability [38-39]. However, Coulomb scattering is dominant for bilayer graphene and the substrate surface polar phonon induced field is to some extent screened by the additional graphene layers [39]. Recently it has been shown that the substrate dielectric constant plays an important role in scattering in graphene. Theoretical predictions show that for dielectric constant , Coulomb scattering dominates, while for dielectric constant , short-range scattering dominates, as Coulomb scattering is more strongly screened for materials with a larger dielectric constant. In fact, our observed behaviour is consistent with the theory suggesting that scattering from charged impurities is dominant in graphene. We introduce a relaxation-time approximation and treat the unscreened Coulomb potential as [1,5] where Q is the charge of impurities. Based on the Boltzmann transport theory, we can obtain the bilayer graphene resistivity with massless Dirac-fermions (MDF) at low energies as. For high temperature , , we can obtain the bilayer graphene resistivity as[47], where is the density of impurities per unit volume, is the permittivity of the semiconductor, and is the charge state of the impurity. This shows that the resistance of bilayer graphene limited by Coulomb scattering increases as increases and decreases with increasing temperature. Considering the above analysis, we deduce that the temperature dependence of resistance in bilayer graphene is mainly determined by Coulomb scattering. The short-range scattering is independent of temperature for bilayer graphene, as the density-of-states, the matrix element and the screening function are all energy independent. As a result of the parab olic band structure of bilayer graphene, the energy averaging of the Coulomb scattering time can give rise to the resistivity decreasing proportionality to temperature : . Based on the above discussion, we fit the measured resistance in Fig.3a by using the following model for bilayer graphene:, where and are the resistance due to the Coulomb and short-range scatterings, respectively. Fig.3b shows the relative resistance change under the biased and unbiased magnetic field as a function of temperature, and the dotted line is the fit following the equation , where is the energy gap. The opening of the energy gap due to a potential difference between the two layers and Coulomb interactions could be a cause for this. These considerations explain qualitatively why the resistance of bilayer graphene decreases with increasing temperature. Note that the relative resistance change is a strong function of temperature. At temperatures of 2Kà ¯Ã¢â€š ¬Ã‚ ­180K and 220Kà ¯Ã¢â€š ¬Ã‚ ­250K, the relative resistance strongly increases as temperature increases, indicating that an energy gap forms due to many-body correction in Landau Level. When the temperature incr eases to T >250K, the relative resistance is roughly independent of the increasing temperature; this indicates that the energy gap is mostly stable at high temperatures. On the other hand, with the temperature increase from 180K to 220K, the relative resistance dependence of temperature shows a sharp decrease, which indicates that the energy gap shows an anomalous thermally activated behaviour as a function of temperature. For zero gate voltage (i.e., neutrality point), we measured changes in longitudinal resistance as a function of applied perpendicular field B. Fig. 4a shows the four-terminal longitudinal resistance of bilayer graphene as a function of magnetic field at T= 2K at the charge-neutrality point. We have plotted the resistance per square, because it is independent of a size effect of the sample. As seen from Fig. 4a, the resistance increases nonlinearly with the magnetic field strength followed by a plateau-like phase. One should note that the plateau-like phase in Fig. 4b disappears at higher temperatures. One possible explanation is the augmented sublattice spin-splitting due to the high surface-impurity concentration of the graphene layer [18]. The origin of the nonlinear magnetoresistance increment behaviour is the splitting of Landau level that gives rise to a bandgap opening at the zero energy level [32-34]. In our measurements, we fit our results to an analytical approximation for the non-linear resistance , where is the Boltzmann constant. We found that our results are in good agreement with this equation. These considerations explain qualitatively why the nonlinear resistance increases with the magnetic field. Fig. 5 shows the resistance of bilayer graphene as a function of electric field (E) under different magnetic fields. The dependent characteristics are symmetric due to the chirality of graphene electrons when an applied electric field changes from E to E. The normalized resistance curve describes the response under the applied magnetic field in the range of B=0T to B=12T and the temperatures of 2-340K. The results demonstrate that when the magnetic field increases from 0T to 12T at low temperatures (2à ¯Ã¢â€š ¬Ã‚ ­200K) and low electric field (E), the resistance of bilayer graphene drops significantly. The larger slump in the resistance at lower temperature T=2K and low electric field as the increasing of electric field are due to Coulomb scattering by impurities, which is a strong function of temperature. On the other hand, at high temperatures (T >200K) and electric fields (E>0.01 ), the resistance of bilayer graphene show a linear decrease. This can be explained by the scatteri ng from thermally excited surface polar phonons of the substrate being screened by the additional top graphene layers [39]. This further confirms that at high temperatures, the scattering induced by the electric field on the substrate surface polar phonons is significantly screened between top and bottom layers in bilayer graphene. In our experiment, temperature and magnetic field dependence of resistance of bilayer graphene was investigated. Intrinsic semiconductor behaviour at the range of temperature is 2K-340K was observed. The strange sharp threshold-like decrease in resistance around 200K is unexpected, and we attribute it to the presence of mesoscopic ripples between the top and bottom layer. Our results reveal that the energy gap in the bilayer graphene is thermally dependent. This potentially indicates the sublattice symmetry breaking and an energy gap formation due to Landau Level splits. The obtained results are important for the better understanding of magnetic field induced high resistance and provide indications of a theoretically predicted magnetic field induced excitonic gap.

Experimental section The bilayer graphene samples for this study were prepared using mechanical exfoliation techniques [2] from the bulk highly oriented pyrolitic graphite (grade ZYA, SPI Supplies) and transferred onto the surface of a lightly doped silicon substrate covered with a 300-nm thick layer of thermally grown , The doped silicon substrate and were used as back-gate and gate dielectric, respectively. Graphene electrical electrodes were patterned using photolithography techniques.

Electronic transport measurements have been carried out on multiple samples, using PPMS (Quantum Design) with a fixed excitation current of 10 . Electrical measurements were performed in the temperature range 2K ~340K and a magnetic field up to 12T was applied. In order to enhance electrical transport, the sample was cleaned in situ by the mag netic and electric field. Four-terminal electrical measurements were used for transport characterization.
