Four Tips for Becoming a Franchisee

If you want to become a franchisee, the tips below can help you to find the perfect opportunity.

Be focusd on your preference. On the stage of decision-making, the bottom line is: Don' t rule out a business without learning or seeing what the day-to-day will look like. For instance, think about a mom returning to the work force who knows she wants to interact with children on a daily basis. Among the hundreds of options there, she needs to decide if she would like to be hands on as a teacher or if she would rather manage a facility that tutors children in math. Deciding between the two is easy if she considers which day-to-day position she would prefer and how that will impact her other goals. Be proactive with your research. After you've determined what role you want in a franchise, it' s important to start researching different options. Physically visit many different franchise locations and browse the web and then determine what will be a fit in your community.

Make sure the franchisor has experience. Before signing on to a franchise, it is essential to ask the franchisor about the executive team and its past industry experience. Find out if the company leaders have had significant experience at another franchise and are now applying that knowledge successfully.

Read the franchise disclosure document carefully. The first thing to look at is how much a franchise would cost to purchase. Make sure you have a financial advisor who can look at that item with you and see the type of profit a franchisee can make on average. It' s also important to take a look at the post-termination clause in the agreement to make sure that when you want to leave the business, you know the terms well and your interests are properly protected.

1.Decide on a business with learning or seeing what the day-to-day will look like.()

2.Before you' ve determined what role you want in a franchise, it's time to start the business.()

3.Before signing on to a franchise, the essential job is to ask the franchisor about the executive team and its past industry experience.()

4.The first thing to look at is how long a franchise would take to purchase.()

5.To make sure that when you want to leave the business, you have made enough money and you are satisfied with that.()

Happiness can be described as a positive mood and a pleasant state of mind. According to recent polls (民意测验) sixty to seventy percent of Americans consider themselves to be moderately happy and one in twenty persons feels very unhappy. Psychologists have been studying the factors that contribute to happiness. It is not predictable nor is a person in an apparently ideal situation necessarily happy. The ideal situation may have little to do with his actual feelings. A good education and income are usually considered necessary for happiness. Though both may contribute, they are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs. The rich are not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly because they have more opportunity to control their lives. Yet people with a high income and a college education may be less happy than those with the same income and no college education. Poor health does not rule out happiness except for the severely disabled or those in pain. Learning to cope with a health problem can contribute to happiness. Those with a good sex life are happier in general, but those who have a loving, affectionate relationship are happier than those who rely on sex alone. Love has a higher correlation with happiness than any other factor. It should be noted that people quickly get used to what they have, and they are happiest when they feel they are increasing their level no matter where it stands at a given time. Children whose parents were happily married have happier childhoods are not necessarily happier adults. The best formula for happiness is to be able to develop the ability to tolerate frustration, to have a personal involvement and commitment, and to develop self-confidence and self-esteem. It can be inferred from the passage that______.
A.happiness is predictable
B.a person in an apparently ideal situation must be happy
C.the rich are likely to be happier than the middle-income group
D.happiness is not necessarily connected to one's situation in society

在美国，资本在GDP中的份额为30%左右；产出的平均增长为每年3%左右；折旧率为每年4%左右；资本—产出比率为2.5左右。假设生产函数是柯布—道格拉斯生产函数，因此，资本在产出中的份额是不变的，而且，美国已经处于稳定状态。
a．在初始稳定状态，储蓄率应该是多少？[提示：使用稳定状态的关系式：sy=(δ+n+g)k]
b．在初始稳定状态，资本的边际产量是多少？
c．假设公共政策提高了储蓄率，从而使经济达到了资本的黄金律水平。在黄金律稳定状态，资本的边际产量将是多少？比较黄金稳定状态的边际产量和初始稳定状态的边际产量，并解释。
d．在黄金律稳定状态，资本—产出比率将是多少？(提示：对柯布—道格拉斯生产函数来说，资本—产出比率与资本的边际产量是相关的。)
e．要达到黄金律稳定状态，储蓄率必须是多少？
In the United States, the capital share of GDP is about 30 percent; the average growth in output is about 3 percent per year; the depreciation rate is about 4 percent per year; and the capital-output ratio is about 2.5. Suppose that the production function is Cobb-Douglas, So that the capital share in output is constant, and that the United States has been in a steady state.
a．What must the saving rate be in the initial steady state？ [Hint: Use the steady-state relationship, sy=(δ+n+g)k]
b．What is the marginal product of capital in the initial steady state？
c．Suppose that public policy raises the saving rate So that the economy reaches the Golden Rule level of capital. What will the marginal product of capital be at the Golden Rule steady state？ Compare the marginal product at the Golden Rule steady state to the marginal product in the initial steady state. Explain.
d．What will the capital-output ratio be at the Golden Rule steady state？ (Hint: For the Cobb-Douglas production function, the capital-output ratio is related to the marginal product of capital.)
e．What must the saving rate be to reach the Golden Rule steady state？

Every culture attempts to create a "universe of discourse" for its members, a way in which people can interpret their experience and convey it to one another. Without a common system of codifying sensations, life would be absurd and all efforts to share meanings doomed to failure. This universe of discourse—one of the most precious of all cultural legacies—is transmitted to each generation in part consciously and in part unconsciously. Parents and teachers give explicit instruction in it by praising or criticizing certain ways of dressing, of thinking, of gesturing, of responding to the acts of others. But the most significant aspects of any cultural code may be conveyed implicitly, not by rule or lesson but through modeling behavior. A child is surrounded by others who, through the mere consistency of their actions as males and females, mothers and fathers, salesclerks and policemen, display what is appropriate behavior. Thus the grammar of any culture is sent and received largely unconsciously, making one's own cultural assumptions and biases difficult to recognize. They seem so obviously right that they require no explanation.
In The Open and Closed Mind, Milton Rokeach poses the problem of cultural understanding in its simplest form, but one that can readily demonstrate the complication of communication between cultures. It is called the "Denny Doodlebug Problem. "Readers are given all the rules that govern this culture: Denny is an animal that always faces North, and can move only by jumping; he can jump large distances or small distances, but can change direction only after jumping four times in any direction; he can jump North, South, East or West, but not diagonally. Upon concluding a jump his master places some food three feet directly West of him. Surveying the situation, Denny concludes he must jump four times to reach the food. No more or less. And he is right. All the reader has to do is to explain the circumstances that make his conclusion correct.
The large majority of people who attempt this problem fail to solve it, despite the fact that they are given all the rules that control behavior. in this culture. If there is difficulty in getting inside the simplistic world of Denny Doodlebug—where the cultural code has already been broken and handed to us—imagine the complexity of comprehending behavior. in societies whose codes have not yet been deciphered, and where even those who obey these codes are only vaguely aware and can rarely describe the underlying sources of their own actions.
We acquire the greater part of our cultural codes by ______.
A．creating a universe of discourse
B．imitating the behavior. of others, especially those of the previous generation
C．sharing the same experiences with other people
D．taking in the various information we're given with no discrimination
