Results of a Study using the Motivation Strategies for Learning Questionnaire (MSLQ) in an Introductory Engineering Graphics CourseAaron C. Clark1 Jeremy V. Ernst2 Alice Y. Scales3Abstract – This paper will present data related to a study conducted at NC State University in the spring of 2008 that focused on student motivation in an introductory graphics course. This study conducted a motivation and learning assessment using the Motivated Strategies for Learning Questionnaire (MSLQ) Attitude Survey. The motivational portion of MSLQ focuses on six areas associated with student learning and motivation. These areas were intrinsic goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy learning performance, and test anxiety. Findings from the study included the identification of enduring motivational factors for learning graphics education. Insights into the strategic learning process of students in a graphics education course will be discussed. Also, areas of concern for future pedagogical development and course improvement will be highlighted.Keywords: MSLQ, Introductory Graphics Course,I NTRODUCTIONMany motivational processes are responsive to individual properties associated with tasks, the classroom, or the context within student engagement [Wolters & Pintrich, 11]. Literature on student motivation identifies many beliefs and constructs, but control, competence, and self-regulated strategic learning remain chief among them [Shell & Husman, 9]. Internal pressures also serve as strong motivators in adult learners [Knowles, Holton, & Swanson, 4, pp. 64-66]. An attitude of self-determination resides at the nucleus of intrinsic motivation [Johari & Bradshaw, 5]. This self-determined attitude is primarily a result of feeling competent and/or independent. In adults, feelings of intellectual competence can be highly motivational when paired with internal pressures that serve as a driving force. Self-determination theory research has placed a large amount of attention on, not only intrinsic motivation, but also extrinsic motivation. Extrinsic motivation refers to “engaging in an activity to obtain an outcome separable from the activity itself” [Vansteenkiste, Timmermans, Lens, Soenens, & Van den Broeck, 10, pp. 388]. A study conducted by Bye, Pushkar, & Conway [2] at Concordia University identifies intrinsic motivation as a predictor of positive classroom effect, while self-improvement and personal growth were found to be highly valued in comparison with extrinsic goals, further distinguishing between intrinsic and extrinsic motivation.1 NC State University, Box 7801, Raleigh, NC 27695-7801, aaron_clark@2 NC State University, Box 7801, Raleigh, NC 27695-7801, jeremy_ernst@3 NC State University, Box 7801, Raleigh, NC 27695-7801, alice_scales@Student motivation possesses a value component involving students’ goals and beliefs about the importance of a task or their personal interest in an application. Motivational value has been conceptualized through various approaches (e.g., learning vs. performance goals, intrinsic vs. extrinsic orientation, task value, and intrinsic interest); this motivational component effectively concerns students' motives for the completion of a task [Pintrich & De Groot, 8]. Beyond beliefs pertaining to importance and interest is self-efficacy. Students’ perceived self-efficacy might influence the process by which he or she selects activities to participate in or complete. There are many circumstances where students assume and perform activities they deem themselves capable of successfully completing and avoid those they believe exceed their ability [Yang, 12]. This paper will examine the results of a study conducted at North Carolina State University that looked at the type of motivation exhibited by students taking an introductory engineering class.M OTIVATED S TRATEGIES FOR L EARNING Q UESTIONNAIRET he Motivated Strategies for Learning Questionnaire (MSLQ) is an instrument designed to evaluate “college students’ motivational orientation and use of different learning strategies for a college course” [Pintrich, Smith, Garcia, and McKeachie, 8]. The broad cognitive analysis of motivation and learning strategy, paired with the social cognitive view of motivation and self-regulated learning, serves as the foundation of MSLQ. The MSLQ consists of two major sections: a motivation section and a learning strategies section. The motivation segment has 31 items that evaluate students’ goals and value beliefs, students’ beliefs about skills necessary to succeed, and test anxiety associated with a specific course [Duncan & McKeachie, 3]. Duncan & McKeachie further differentiate the learning strategy section of the MSLQ as identifying students’ use of different cognitiv e and metacognitive strategies as well as student management of resources. The motivation section and the learning strategies section of the MSLQ include 81 items. Each item is rated using a 7-point Likert-type scale. The rating scale ranges from one (not at all true of me) to seven (very true of me).Pintrich, Smith, Garcia, & McKeachie [8] describe the motivation scales of the MSLQ as vehicles to acquire information associated with value, expectancy, and affect. Value assists in exploring intrinsic and extrinsic goal orientation, expectancy targets beliefs about learning and self-efficacy, and affect gauges test anxiety. Learning strategies investigated through the motivation scales are drawn from a broad compilation of cognitive research representing cognitive processing and its affect on student learning [Lynch, 6].Numerous MSLQ studies have been conducted that present evidence of internal consistency, reliability, and predictive validity of the instrument [Pintrich, Smith, Garcia, & McKeachie, 8; Artino, 1; Duncan & McKeachie, 3]. The MSLQ represents a method to accurately and holistically gage student motivation and self-regulated learning grounded by a theoretical basis. The MSLQ allows student learning researchers to move beyond traditional examinations of individual differences in learning styles to gain insight into the motivation and learning specifically occurring in a targeted college course. In this investigation, an introductory engineering graphics course wasselected to investigate intrinsic goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy learning performance, and test anxiety with the MSLQ Attitude Survey.M ETHODOLOGYThis targeted investigation utilized the results of 31 motivational questions MSLQ Attitude Survey to examine six proposed null hypotheses concerning motivation and satisfaction of student learning. These null hypotheses were: 1) Ho: Student intrinsic goal orientation elements are independent components of motivation and learning. 2) Ho: Student extrinsic goal orientation elements are independent components of motivation and learning. 3) Ho: Student task value elements are independent components of motivation and learning. 4) Ho: Student controls of learning beliefs are independent components of motivation and learning. 5) Ho: Student self-efficacy and learning performance elements are independent components of motivation and learning. 6) Ho: Student test anxiety elements are independent components of motivation and learning.These hypotheses guided the motivation and learning investigation utilizing the MSLQ Attitude Survey as the means for data acquisition. Specifically, the six hypotheses structure the investigation to identify enduring motivational factors for learning graphics in the introductory engineering graphics course at NC State University.To better gauge indicators of student attitude and motivation, the MSLQ data analysis was shortened. As prescribed by Matthews [7] to solely measure motivation concerning goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy learning performance, and test anxiety, the MSLQ analysis was limited to 31 questions specifically targeted to student motivation. Additionally, Matthews identified the MSLQ item equivalent subsets to provide a targeted analysis of the six focal areas associated with student learning and motivation.In the 10th week of the 2008 spring semester the course instructors administered the MSLQ instrument to student participants in the introductory engineering graphics course. The questionnaire took the participants approximately 15 minutes to complete. One hundred and sixty one students in seven separate sections of GC 120 (Foundations of Graphics) completed and returned the instrument. One of the 161 participants failed to complete items 24 and 29 of the targeted subgroup analysis, but the researchers decided to include this questionnaire in the completed group. The researchers gathered the completed instruments from the course instructors, entered the MSLQ data, tabulated the questionnaire results, analyzed the target items, and formed conclusions based on the six identified student learning and motivation areas.R ESULTSThe proposed hypotheses were evaluated using a one-sample calculation of variance. The test of independence tabulates MSLQ instrument items in their designated categories and computes a chi-square value. This procedure uses the critical value to evaluate the proportional value derived from the Chi-Square table. A significant p-value foran item in a category demonstrates that it is independent of the other items and, therefore, has no relationship to the other items in its category or the category itself.The identified MSLQ item equivalents to investigate intrinsic goal orientation were 1, 16, 22, and 24 (See Table 1). Within the item equivalents that measured intrinsic goal orientation, item 16 had the highest average, while item 24 had the lowest. As a group, the intrinsic goal orientation items averaged 4.68 on the seven-point scale. The sampling variance, reported in the data summations, was due to a statistical fluctuation in the responses on intrinsic goal orientation sub grouped items identified in the six student learning and motivation areas. Additionally, evaluation of the chi-square statistic and the proportional value associated with each item identified all four MSLQ items within their student learning and motivation area as significantly different from one another, given the predetermined alpha level of significance (0.05). Items 1, 16, 22, and 24 all had p-values smaller than 0.05, therefore the null hypothesis that intrinsic goal orientation elements are independent components of motivation and learning could not be rejected because there is evidence that the questions were independent of the category and each other by virtue of their significant p-values.Table 1. MSLQ Intrinsic Goal OrientationThe identified item equivalents to investigate extrinsic goal orientation were MSLQ items 7, 11, 13, and 30 (See Table 2). Within the item equivalents of extrinsic goal orientation, item 13 had the highest average, while item 30 had the lowest. As a group, the extrinsic goal orientation items averaged 5.35 on the seven-point scale. Additionally, reporting and evaluation of the chi-square statistic and the proportional value associated with each item identified three of the four items were significantly different from one another. Item 13 was found not to significantly differ within the subgroup. Items 7, 11, and 30 all had a p-value smaller than 0.05, therefore, the null hypothesis that statedthat extrinsic goal orientation elements are independent components of motivation and learning also failed to be rejected.Table 2. MSLQ Extrinsic Goal OrientationThe identified item equivalents to investigate task value were MSLQ items 4, 10, 17, 23, 26, and 27 (See Table 3). Within the item equivalents for task value, the six items provide participant averages relatively close to one another. As a group, the task value items averaged a 5.16 on the seven-point scale. The sampling variance again was due to a statistical fluctuation in participant responses on the task value sub grouped items. Likewise, reporting and evaluation of the chi-square statistic and the proportional value associated with each item identified all six of the MSLQ items within their student learning and motivation area as significantly different from each other. The p-values for items 4, 10, 17, 23, 26, and 27 were all lower than the established cut-off value of 0.05, therefore, the null hypothesis that stated that task value elements are independent components of motivation and learning could not be rejected.Table 3. MSLQ Task ValueThe identified item equivalents that examined control of learning beliefs were MSLQ items 2, 9, 18, and 25 (See Table 4). Within the item equivalents of control of learning beliefs, item 18 had the highest average while item 25 had the lowest. As a group, the control of learning beliefs items averaged 5.62. The sampling variance was due to the variation in the participants’ responses on control of learning beliefs sub grouped items identified within the six student learning and motivation areas. The reporting and evaluation of the chi-square statistic, and the proportional value associated with each item, identified three of the four MSLQ items within their student learning and motivation area as significantly different from one another, given the predetermined alpha level of significance (0.05). Item 18 was found not to differ within the response subgroup. Items 2, 9, and 25 had a p-value lower than the critical value of 0.05, therefore, again the results failed to reject the null hypothesis that control of learning beliefs is an independent component of motivation and learning.Table 4. MSLQ Control of Learning BeliefsThe identified item equivalents to investigate self-efficacy learning performance are MSLQ items 5, 6, 12, 15, 20, 21, 29 and 31 (See Table 5). Within the item equivalents of self-efficacy learning performance, the eight items present participant averages relatively close to one another. As a group, the self-efficacy learning performance items averaged a 5.47 on a seven-point scale. The sampling variance again is due to the statistical fluctuation in participant response on this sub group of items. Additionally, the evaluation of the chi-square statistic and the proportional value associated with each item identified six of the eight MSLQ items within their student learning and motivation area as significantly differing from one another based on the predetermined alpha level of significance (0.05). Items 20 and 21 were found not to significantly differ within the response subgroup; however, items 5, 6, 12, 15, 29 and 31 were lower than the critical p-value set at 0.05; therefore, it was not possible to reject the null hypothesis that self-efficacy and learning performance are independent components of motivation and learning.Table 5. MSLQ Self-Efficacy Learning PerformanceThe identified item equivalents to investigate test anxiety are MSLQ items 3, 8, 14, 19, and 28 (See Table 6). Within the items used to examine test anxiety, item 14 had the highest average while item 3 had the lowest. As a group, the task value items averaged 3.74 on the seven-point scale. The sampling variance was again due to the fluctuation in participants’ responses. Evaluation of t he chi-square statistic and the proportional value associated with each item indicated that all five of the MSLQ items significantly differed from each other and were smaller than the predetermined value for significance. Since items 3, 8, 14, 19, and 28 were not found to be significant, the null hypothesis that test anxiety is an independent component of motivation and learning failed to be rejected.Table 6. MSLQ Test AnxietyC ONCLUSIONSItem 13 (“If I can, I want to get better grades in this class than most of the other students”); in the Extrinsic Goal Orientation subgroup, item 18 (“If I try hard enough, then I will understand the course materials”); in the Control of Learning Beliefs subgroup, item 20 (“I’m confident I can do an excellent job on the assignments and test in this course”) and item 21 (“I expect to do well in this class”) of the Self-Efficacy Learning Performance subgroup were identified by the study as continuing motivational and learning factors for learning engineering graphics in the introductory engineering graphics course at NC State University. Considering the fact that these statements “standout” among the others and that each in some way is associated with the level of understanding and the grade they wish to receive in class, grades are still a good motivation factor to consider with these participants. The ability to do well and see relevance in what is being taugh t is also paramount to a student’s motivation in a course, like a fundamentals of engineering graphics. From the data collected for this study, it can be observed that grades, relevance of content, and understanding subject matter are the main factors tha t affect students’ motivation. Based on these findings, more research in areas of strategic learning of students in engineering graphics courses as it relates to their abilities to be self-motivated needs to be conducted, particularly as the structure and delivery methods of engineering graphics courses are rapidly changing. Also, considering the change and growth of new areas and concepts in the engineering graphics profession, how can we utilize contemporary methods to increase student motivation? Again, more investigation is needed in this area of student motivation as the profession works to educate future professionals that use graphics for the 21st century.R EFERENCES[1] Artino, A.R.

With the rapid development of technology, online education has become increasingly popular. Discuss the advantages and disadvantages of online education, and give your own opinion on whether it is a positive or n egative change.”Example:In recent years, the advent of online education has revolutionized the waywe acquire knowledge.

Students can attend classes from the comfort of their homes, which is particularly beneficial for those with busy schedules. Moreover, online platforms often offer a wide range of resources and interactive tools that can enhance the learning experience.However, there are also some drawbacks to online education. One major concern is the lack of face-to-face interaction, which can lead to feelings of isolation and reduced social skills. Additionally, self-discipline and time management are crucial for online learners, as they need to stay motivated and focused without the guidance of a traditional classroom environment.In my opinion, online education is a positive change. While it does have its drawbacks, the flexibility and accessibility it offers far outweigh the negatives. With the right mindset and support, online education can empower individuals to pursue their dreams and contribute to societal progress.Analysis:The essay presents a clear and concise argument about the advantages and disadvantages of online education.

Scarcely a man in the 500 does not carry the scars of accident crashes. The mark of the plastic surgeon is everywhere, and burned skin is common. Sometimes a driver^ scars are invisible, part of his heritage. Two young drivers, Billy Vukovich and Gary Bettenhausen, raced in their first 500 in 1968. Less than 20 years before, their fathers also competed against one another on the Indy track-and died there.All this the drivers accept. Over the years, they have learned to trust their own techniques, reflexes, and courage. They depend, too, on a trusted servant-scientific engineering. Though they may not have had a great deal of schooling (an exception is New Zealand’s Bruce McLaren, who had an engineering degree), many drivers are gifted mechanics, with a feeling for their engines that amount to kinship.A few top drivers have become extremely wealthy, with six-figure incomes from prize money, endorsement, and jobs with auto-product manufacturers. Some have businesses of their own. McLaren designs racing chassis (底盘).Dan GumeyJs California factory manufactured the chassis of three of the first four cars in the 1968 Indy 500, including his own second place car.

The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The worlds largest Milu Deer Nature Reserve is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands.The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife. Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wet-lands. Wetlands are important because they can also prevent floods. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.Luckily, more and more people are beginning to realize the importance Of wetlands and wildlife. Every year, on February 2, many activities are held to tell people more about wet-lands.The World Wetlands Day is on. ______ .B. June 25C. February 2D.

Future generations could be living well into their second century and still doing Sudoku, if life expectancy predictions are true. Increasing by two years every decade, they show no signs of flattening out. Average lifespan worldwide is already double what it was 200 years ago. Since the 1980s, experts thought the increase in life expectancy would slow down and then stop, but forecasters have repeatedly been proved wrong.The reason behind the steady rise in life expectancy is “the decline in the death rate of the elderly”, says Professor Tom Kirkwood from Newcas tle University. He maintains that our bodies are evolving to maintain and repair themselves better and our genes are investing in →this process ←to put off the damage which will eventually lead to death. As a result, there is no ceiling imposed by the real ities of the ageing process. “There is no use-by-date when we age. Ageing is not a fixed biological process," Tom says.A large study of people aged 85 and over carried out by Professor Kirkwood discovered that there were a remarkable number of people enjoying good health and independence in their late 80s and beyonD. With people reaching old age in better shape, it is safe to assume that this is all due to better eating habits, living conditions, education and medicine.There are still many people who suffer from major health problems, but modem medicine means doctors are better at managing long-term health conditions like diabetes, high blood pres- sure and heart disease. “We are reaching old age with less accumulative damage than previous generations, we are less damaged," says Professor KirkwooD. Our softer lives and the improvements in nutrition and healthcare have had a direct impact on longevity.Nearly one-in-five people currency in the UK will live to see their 100th birthday, the Office for National Statistics predicted last year. Life expectancy at birth has continued to increase in the UK——from 73.4 years for the period 1991 to 1993 to 77.85 years for 2007 to 2009. A report in Science from 2002 which looked at life expectancy patterns in different countries since 1840 concluded that there was no sign of a natural limit to life.Researchers Jim Oeppen and Dr. James Vaupel found that people in the country with the highest life expectancy would live to an average age of 100 in about six decades. But they stopped short of predicting anything more."This is far from eternity: modest annual increments in life expectancy will never lead to immortality,” the researchers saiD.We do not seem to be approaching anything like the limits of life expectancy, says Professor David Leon from the London School of Hygiene and Tropical Medicine. “There has been no flattening out of the best the groups which everyone knows have good life expectancy and→ low mortality←. ”he says.These groups, which tend to be in the higher social and economic groups in society, can live for several years longer than people in lower social groups, prompting calls for an end to inequalities within societies.Within populations, genes also have an important role to play in determining how long we could survive for, but environment is still the most important factor.It is no surprise that healthy-living societies like Japan have the highest life expectancies in the worlD. But it would still be incredible to think that life expectancy could go on rising forever. “I would bet there will be further increases in life expectancy and then it will probably begin to slow,” says Tom, “but we just don’t know.”The underlined phrase “low mortality” in Paragraph 8 could best be replaced by “→←".A. short life spanB. low death rateC. low illness rateD. good health condition23.(单项选择题)(每题 2.00 分) For grammar teaching, if the rule is given first and explained and the student then has to apply the rule to given situation, the method is definedas______methoD.A. deductiveB. inductiveC.

Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be reviveD. Biological death occurs when changes in the organism lead to the disintegration of vital cells and tissues. Death is then irreversible and final.Scientists have been seeking a way to prolong the period of clinical death so that the organism can be revived before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body^ metabolism, cooling delays the processes leading to biological death.To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called KetA. The scientists put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from its body. The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped; clinical death set in.this point the scientists pumped blood into its body in the direction of the heart and started artificial breathing. After two minutes the monkey’s heart became active once more. Aft er fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her heaD. After six hours, when the scientists tried to give her a penicillin injection. Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.One characteristic of clinical death is______.A. lasting damage to the lungsB. destruction of the tissuesC. temporary non-functioning of the heartD. that the organism cannot be revived28.(单项选择题)(每题 2.00 分) Which of the following activities actually does not involve writing?→ ←.A.

Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation. In thisextreme, of course, white salt would be left behind; this, by the way, is how much of the table salt we use is actually obtaineD.The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreaseD. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation.Normally, in hot regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behinD. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeareD. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.In the Weddell Sea, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portion of the oceans of the worlD.It can be known from the passage that increase in the salinity of ocean water is caused by______.A. melting of sea iceB. precipitationC. evaporationD. supplement of salt33.(单项选择题)(每题 2.00 分) Mr. King works in a shop and drives a car for the manager.

Future generations could be living well into their second century and still doing Sudoku, if life expectancy predictions are true. Increasing by two years every decade, they show no signs of flattening out. Average lifespan worldwide is already double what it was 200 years ago. Since the 1980s, experts thought the increase in life expectancy would slow down and then stop, but forecasters have repeatedly been proved wrong.The reason behind the stead y rise in life expectancy is “the decline in the death rate of the elderly”, says Professor Tom Kirkwood from Newcastle University. He maintains that our bodies are evolving to maintain and repair themselves better and our genes are investing in →this process ←to put off the damage which will eventually lead to death. As a result, there is no ceiling imposed by the realities of the ageing process. “There is no use-by-date when we age. Ageing is not a fixed biological process," Tom says.A large study of people aged 85 and over carried out by Professor Kirkwood discovered that there were a remarkable number of people enjoying good health and independence in their late 80s and beyonD. With people reaching old age in better shape, it is safe to assume that this is all due to better eating habits, living conditions, education and medicine.There are still many people who suffer from major health problems, but modem medicine means doctors are better at managing long-term health conditions like diabetes, high blood pres- sure and heart disease. “We are reaching old age with less accumulative damage than previous generations, we are less damaged," says Professor KirkwooD. Our softer lives and the improvements in nutrition and healthcare have had a direct impact on longevity.Nearly one-in-five people currency in the UK will live to see their 100th birthday, the Office for National Statistics predicted last year. Life expectancy at birth has continued to increase in the UK——from 73.4 years for the period 1991 to 1993 to 77.85 years for 2007 to 2009. A report in Science from 2002 which looked at life expectancy patterns in different countries since 1840 concluded that there was no sign of a natural limit to life.Researchers Jim Oeppen and Dr. James Vaupel found that people in the country with the highest life expectancy would live to an average age of 100 in about six decades. But they stopped short of predicting anything more."This is far from eternity: modest annual increments in life expectancy will never lead to immortality,” the researchers saiD.We do not seem to be approaching anything like the limits of life expectancy, says Professor David Leon from the London School of Hygiene and Tropical Medicine. “There has been no flattening out of the best the group s which everyone knows have good life expectancy and→ low mortality←. ”he says.for several years longer than people in lower social groups, prompting calls for an end to inequalities within societies.Within populations, genes also have an important role to play in determining how long we could survive for, but environment is still the most important factor.It is no surprise that healthy-living societies like Japan have the highest life expectancies in the worlD. But it would still be incredible to think that life expectancy could go on rising forever. “I would bet there will be further increases in life expectancy and then it will probably begin to slow,” says Tom, “but we just don’t know.”Which statement below is TRUE concerning life expectancy according to thepassage?→←.A.

His assessment weighed the pros and cons of e-book technology’s impact on social rela tionships, the environment, the economy,etC. Before you curl up with an e-book, consider the disadvantages.They increase eyestrain due to poor screen resolution, replace a relatively cheap commodity with a more expensive one, and displace workers in print book production and traditional publishing. E-books make it easy to share data, thereby threatening copyright agreements and reducing compensation of authors, as well as creating no biodegradable trash. On the other hand, e-books save paper and trees, reduce the burden of the carrying and storing of printed books, promote self- sufficiency in learning, and make reading a collaborative experience online. They also create new jobs for writers and artists and encourageself-publishing. In final analysis, Ohler points out, e-books should gain society’s approval if a few conditions are met: make them biodegradable and recyclable,solve the problem of eye fatigue,be sure the “have-nots” get the technology,and support e-book training in schools and business.What is e-books negative impact on social relationships?______.A. They create new jobs only for writers.B. Fewer and fewer people have access to new technology.C. They may threaten some traditional trades.。

a rXiv:h ep-ph/58144v112Aug25A Systematic Study on Nonrelativistic Quarkonium Interaction Sameer M.Ikhdair ∗and Ramazan Sever †∗Department of Electrical and Electronic Engineering,Near East University,Nicosia,North Cyprus,Turkey †Department of Physics,Middle East Technical University,Ankara,Turkey.PACS NUMBER(S):12.39.Pn,14.40-n,12.39.Jh,14.65.-q,13.30.Gd Key Words:Bound state energy,Decay widths,Shifted large N-expansion method,Quarkonia,Mesons (February 2,2008)Typeset using REVT E XAbstractA recently proposed strictly phenomenological static quark-antiquark poten-tial belonging to the generality V(r)=−Ar−α+κrβ+V0is tested with heavyquarkonia in the context of the shifted large N-expansion method.This non-relativistic potential modelfits the spin-averaged mass spectra of the c band cc and bb states.Our results are compared with other models to gauge the reliabilityof the predictions and point out differences.I.INTRODUCTIONThe charm-beauty(B c)quarkonium states provide a unique window into heavy quark dy-namics.The properties of the B c mesons are of special interest,since they are the only quarkonia consisting of two heavy quarks with differentflavours and are also intermediate to the charmonium and bottomonium systems.Additionally,because they carryflavour they cannot annihilate into gluons so are more stable with widths less than a hundred keV.Ex-cited B c meson states lying below BD(and BD∗or B∗D)threshold can only undergo hadronic (pionic)or radiative transitions to the ground pseudoscalar state which then decays weakly. This results in a rich spectroscopy of narrow radial and orbital excitations which are consid-erably more stable than their charmonium and bottomonium analogues.The discovery ofthe B c meson by the Collider Detector at Fermilab(CDF)Collaboration[1]in p(1S)=6.40±0.39±0.13GeV s=1.8T eV with an observed pseudoscalar mass M Bchas inspired new theoretical interest in the study of the B c spectroscopy in the framework of heavy quarkonium theory[2,3,4,5,6,7,8,9,10,11,12,13,14,15].On the other hand,for bottomonium system,the ALEPH collaboration in2002has searched for the pseudoscalar bottomonium meson,ηb,in two-photon interactions at LEP2 with an integrated luminosity of699pb−1collected at e+e−centre-of mass energies from181 GeV to209GeV.One candidate event is found in the six-charged-particlefinal state and none in the four-charged-particlefinal state.The candidateηb(1S)(ηb→K S K−π+π−π+) has reconstructed invariant mass of9.30±0.02±0.02GeV[16].Theoretical estimates(from perturbative QCD and lattice nonrelativistic QCD)to the hyperfine mass splitting for the 1S bottomonium state∆HF(1S)are reported(cf.[16]and references therein).Moreover,the inconsistent Crystal Ball measurement for the pseudoscalar charmonium =3594±5MeV[17]has been given for more than20years,before a new mass,Mηc(2S)measurement of3654±6±8MeV was available by Belle Collaboration in summer of2002 [18]for the exclusive B−→KK S K−π+decays.It is close to theηc(2S)mass observed by the same group in the experiment e+e−−→J/ψηc where Mηc(2S)=3622±12MeV was found[19].It is giving rise to a small hyperfine splitting for the2S charmonium state,∆HF(2S,exp)=Mψ(2S)−Mηc(2S)=32±14MeV[20].Very recently,several more new measurements have been appeared that support the Belle value:BaBar measures3630.8±3.4±1.0MeV[21](an earlier analysis resulted in 3632.2±5.0±1.8MeV[22]),CLEO II gives3642.7±4.1±4.0MeV[23](CLEO III prelim: 3642.5±3.6±?MeV)and a different Belle analysis yields3630±8MeV[24].The∆HF(2S) splitting calculated from a naive average of the central values of all measurements except Crystal Ball is47MeV).Further,the following mass values have been obtained:M J/ψ(1S)= 3096.917±0.010±0.007MeV and Mψ(2S)=3686.111±0.025±0.009MeV.The relative measurement accuracy reached4×10−6for the J/ψ(1S),7×10−6for theψ(2S)and is approximately3times better than that of the previous precise experiments in[25]and[26].The new result for the mass difference is Mψ(2S)−M J/ψ(1S)=589.194±0.027±0.011MeV [2].Consequently,such observations of hyperfine splittings for the2S charmonium and1S bottomonium spectra have inspired new theoretical interest in the study of the hyperfine splittings of the charmonium and bottomonium states as well as their spectra[5,14,27,28,29]. Badalian and Bakker[27]calculated the hyperfine splitting for the2S charmonium state,∆HF(2S,theory)=57±8MeV,in their recent work.Recksiegel and Sumino developed a new formalism[28]based on improved perturbative QCD approach to compute thefine and hyperfine splittings of charmonium and bottomonium[28,29].As a result,one is able to test the validity of the conventional phenomenological potential models where the core potential follow from simple ansatzes by comparing our theoretical predictions of the spectrum of heavy quarkonia in terms of agreement with the experimental data with respect to the estimated uncertainties.Thus,these phenomenological potential models are not a priori connected to a fundamental QCD parameters[4,5,6,7,8].In general, where the masses of bottomonium and charmonium states have been measured,the experi-mental uncertainties are much smaller than the theoretical uncertainties[20].The only two exceptions are the very poorly measured masses ofηb(1S)andηc(2S).With suitable potential model,very good agreement with the observed spectra can be obtained for the charmonium and bottomonium states(e.g.,[15]).These studies established the non-relativistic nature of the heavy quarkonium systems and,in overall,a unified shape of the inter-quark potential in the distance region0.5 r 5GeV−1.In this work we extend our previous analysis of the shifted large-N expansion technique (SLNET)developed for the Schr¨o dinger wave equation[4,30,31,32]and then applied to semirelativistic and relativistic wave equations[5,32,33]to reproduce the hyperfine split-tings of the c b and cc,bical potential form[15].We also calculate the masses of the recently found new charmonium ηc(2S)and the searched bottomoniumηb(1S)mesons together with the hyperfine splittings of their states.The outline of this paper is as following:In Section II,wefirst review briefly the analytic solution of the Schr¨o dinger equation for unequal mass case(m qi=m q j).Section III is devoted for the spin-averaged quarkonium masses of spin triplet states.The leptonic decay widths are briefly reviewed in Section IV.Finally,Section V contains our conclusions.II.SCHR¨ODINGER MASS SPECTRUMWe limit our discussion to the following generality of potentials[5,15,34]:V(r)=−Ar−α+κrβ+V0,(1) where A,κ,αandβare nonnegative constants whereas V0is taking any sign.These static quarkonium potentials are monotone nondecreasing,and concave functions satisfying the condition[4,5,30,32,33]V′(r)>0and V′′(r)≤0.(2) At least ten potentials of this generality,but with various values of the parameters,have been proposed in the literature.Cornell potential hasα=β=1,Lichtenberg potential has α=β=0.75,Song-Lin potential hasα=β=0.5,and the logarithmic potential of Quigg and Rosner corresponds toα=β→0,have been recently studied(cf.e.g.,[4,5,6,30,32,33] and references therein).The Song’s potential used in[34]hasα=β=2/3.Potentials with α=βhave also been popular.Thus,Martin potentialα=0,β=0.1[4,5,6,30,32,33],while Grant,Rosner and Rynes[35]preferα=0.045,β=0.Heikkil¨a,T¨o rnquist and Ono[36] triedα=1,β=2/3.More successful potential known in literature as Indiana potential[37] and the Richardson potential[38].Recently,Motyka and Zalewski[15]have also explored the quality offit in the region0≤α≤1.2,0≤β≤1.1of theα,βplane.They choose the region with coordinatesα=1,β=0.5.In the present work,in order to get a goodfit,we test the second generality(1)with α=1,β=0.5.Therefore,the nonrelativistic phenomenological potential used by Motyka and Zelawiski[15]for the q i q j systems has the formV(r)=−0.325250r−0.78891,(3)where V(r),√b quarkonium we use the reduced massµcb=m c m bb quarkonium are not known or very poorly measured.For two particles system,we shall consider the N−dimensional space Schr¨o dinger equa-tion for any spherically symmetric central potential V(r).Ifψ(r)denotes the Schr¨o dinger’s wave function,a separation of variablesψ(r)=Y l,m(θ,φ)u(r)/r(N−1)/2gives the following radial Schr¨o dinger equation( =c=1)[4,6,30,31,32]−1dr2+[k−(3−a)]m qi +m qjis the reduced mass for the two quarkonium composite particles.Here,E n,ldenotes the Schr¨o dinger binding energy of meson,andproper shift to be calculated later on and l is the angular quantum number.We follow the shifted1/N or1/dr m0 (r0x)m k(4−m)/2,(7) and also the energy eigenvalue expansion[4,5,30,32,33]E n,l=∞m=0Q E m,(8)where x=k2at the end of our calculations.Following the approach presented by Ref.[4,30,32],we give the necessary expressions for calculating the binding energies:E0=V(r0)+Qr20 n r+18µ ,(10)E2=Q16µ+α(1) ,(11) E3=Q2r0V′(r0)+116µ+α(1)+α(2)k+O 1k2 .(14)where the shifting parameter,a,is defined bya=2−(2n r+1) 3+r0V′′(r0)V′(r0) 1/2= 8µr30V′(r0) 1/2,(16) with n r=n−1is the radial quantum number and n is the principal quantum number. Once r0is found via equation(16),then the Schr¨o dinger binding energy of the q iq j system is written asM(q ik becomes smaller as l becomes larger since the parameter+V(r)+V SS,(18)2µwhere V SS is the spin-dependent term.The spin dependent correction to the nonrelativistic Hamiltonian,which is responsible for the hyperfine splitting of the mass levels,is generally used in the form[7,8,39,40,41,42](s1.s2−1V SS−→V HF=32παsq jsubstituted from the prod-4uct of the spins corresponds to the recent assumption that the unperturbed nonrelativisticHamiltonian gives the energy of the triplet states.Since for the states with orbital angular momentum L>0the wave function vanishes at the origin,the shift effect only the S states. Thus,the onlyfirst order effect of this perturbation is to shift the1S0states down in energy by32παs|ψ(0)|2,(20)∆E HF=q jwith the wave function at the origin is calculated by using the expectation value of the potential derivative via[4,5,6,30,42,43]|ψ(0)|2=µdr .(21) In order to apply the last formula one needs the value of the wavefunction at the origin-this is obtained by solving the Schr¨o dinger equation with the nonrelativistic Hamiltonian and the coupling constant.In this approach,the QCD strong coupling constantαs(4µ2),on the renormalization pointµ2is not an independent parameter.It can be connected(in the2µMS 2−1β0Λ(n f)n f.Like most authors(cf.e.g.[4,5,6,7,8,15]),the strong coupling constant3αs(m2c)isfitted to the experimental charmonium hyperfine splitting number∆HF(1S,exp)= 117±2MeV[4,20]yieldsαs(m2c)=0.254.(23) Knowing the coupling at the scale m2c we obtain the couplings at other scales as follows. The number offlavours(n f)is put equal to three for4µ2≤m2c(we are not interested in the region4µ2≤m2s),equal to four for m2b≥4µ2≥m2c and equal tofive for4µ2≥m2b(we are not interested in the region4µ2≥m2t).Then the value ofαs(4µ2=m2c)from(22)is used tocalculateΛ(n f=3).Using the known value ofΛ(n f=4)MSis found.Note that this supports our model since a differentMSchoice of the Hamiltonian would in general lead to a different value of the wave function at the origin and to a different determination ofαs(m2c)from the same hyperfine splitting. Then the estimate ofαs(m2Z)would,of course,be also different.For the hyperfine splitting of the cc and bc)level−92/32MeV-is much bigger/lower than expected from the potential models.In all cases,where comparison with the other models are significantly smaller than the splittings found by Eichten and Quigg[7]and similar to,but usually a little smaller than,the splittings calculated by Gupta and Johnson [44].One can also try to compare our results with more ambitious approaches.A careful analysis in the framework of QCD sum rules[45]finds the hyperfine splitting of the bot-tomonium∆HF(1S,theory)=63+29MeV.The central value agrees to several MeV very well−51with our expectation,but the uncertainty is too large to distinguish between the potential models.A lattice calculation[9]gives the hyperfine splitting∆HF(1S,theory)=60MeVwith a large uncertainty.Again the central value is close to our model,but the uncertainty is big enough to be consistent with all the potential models quoted here.IV.LEPTONIC DECAY WIDTHSThe leading terms in the leptonic decay widths of the heavy quarkonia are proportional to the squares of the wave functions at the origin.Therefore,they are significant only for the S states.For the c b quarkonium systems,we shall consider the decays of the n3S1(vector)states into pairs of charge conjugated charged leptons,e.g.for definiteness into e+e−pairs.For the cc and b=16πα2e2q|ψ(0)|23π .(26)llFor vector mesons containing light quarks this formula leads to paradoxes(cf.[47]and references therein).For quarkonia,however,the main problem seems to be the QCD cor-rection.Thus,in order to get quantitative predictions it is necessary to include higher order corrections which are not known.In order to estimate the missing terms we tried two simple forms.Exponentialization of thefirst correction16αs(m2q)C1(αs(m2q))=exp(−1+16αs(m2q)uncertainty of this estimate.The resulting leptonic widths are collected in Table5.Further, we have the relationΓV→84m2qαs(m2q)C av∆E HF,(29)where C av is the averaged QCD correction factor.With our choice of parameters this formula reduces toΓV→M2V∆E HF,(30)with F(c)=7.07×10−5and F(b)=2.43×10−5.The formula for the leptonic widths of the pseudoscalar c8πf2Bc|V cb|2MB cm2τ 1−m2τM2B cC(αs)is QCD correction factor.Formally this decay constant is defined in terms of the element of the axial weak current0|Aµ(0)|B c(q) =if B c V cb qµ.(33) The QCD correction factor is[48]π 2−m b−m c m c .(34)With our parametersb quarkoniumare found to be f Bc =492MeV and f Bc=338MeV(cf.e.g.,[6].Let us note the convenient relationf2Bc =27µcbM Bc6199∆E HF,(36)where all the parameters are in suitable powers of MeV.V.CONCLUSIONSFigure1shows the behavior of the present potential form in comparison with some other potential forms considered in[4].From thisfigure it is noticed that,all potential forms are nearly the same at large r,but the behavior seem different at very small r(r<0.5GeV−1, about0.1fm),due to the variation of the one-gluon exchange term in each potential model. Further,the present potential model containing six free parameters:the three parameters in the strictly nonrelativistic phenomenological potential(3),the masses of the c and b quarks (4)and the strong coupling constant at the m c scale(22).This model is applicable to all heavy quarkonia below their strong decay thresholds.Consequently,we obtain the c b and c c)quarkonium mass spectra and also their leptonic decay widths in good agreement with up-to-date experimentalfindings.We also give prediction for the cb quarkonium.Our model predicts similar hyperfine splitting for the1S bottomonium and 2S charmonium as in the other potential models[7,15],lattice[49,50]and perturbation QCD [28,29,51].Further,thefine splitting in charmonium is found to be Mψ(1S)−M J/ψ(1S)=597 MeV.Finally,in general,the potential models reproduce the experimental values much better. This feature would be understandable,since the potential models contain much more input parameters than the lattice or perturbative QCD models.ACKNOWLEDGMENTSThis research was partially supported by the Scientific and Technical Research Council of Turkey.The authors wish to thank S.Recksiegel for information on recent QCD-based formalism.Sameer M.Ikhdair would like to thank his wife,Oyoun,and his son,Musbah, for their assistance,patience and love.FIGURESFIG.1.The behavior of the different potential models versus r.REFERENCES[1]CDF Collaboration,F.Abe et al.,Phys.Rev.D58(1998)112004.[2]N.Brambilla et al.,[arXiv:hep-ph/0412158].[3]S.Godfrey,Phys.Rev.D70(2004)054017.[4]S.M.Ikhdair and R.Sever,Int.J.Mod.Phys.A18(2003)4215.[5]S.M.Ikhdair and R.Sever,Int.J.Mod.Phys.A19(2004)1771;ibid.A20(2005)4035;ibid.[arXiv:hep-ph/0406005](in press).[6]S.M.Ikhdair,[arXiv:hep-ph/0504107];ibid.[arXiv:hep-ph/0504176].[7]E.J.Eichten and C.Quigg,Phys.Rev.D49(1994)5845.[8]L.P.Fulcher,Z.Chen,and K.C.Yeong,Phys.Rev.D47(1993)4122;ibid.50(1994)447;L.P.Fulcher,Phys.Rev.D60(1999)074006;ibid.44(1991)2079.[9]C.T.H.Davies et al.,Phys.Lett.B382(1996)131.[10]M.Baldicchi and G.M.Prosperi,Phys.Lett.B436(1998)145;ibid.Phys.Rev.D62(2000)114024;ibid.Fiz.B8(1999)251.[11]W.Kwong and J.Rosner,Phys.Rev.D44(1991)212;ibid.D38(1988)279.[12]S.Gershtein et al.,Phys.Rev.D51(1995)3613.[13]N.Brambilla and A.Vairo,Phys.Rev.D62(2000)094019.[14]D.Ebert,R.N.Faustov and V.O.Galkin,Phys.Rev.D67(2003)014027;ibid.Mod.Phys.Lett.A17(2002)803;ibid.[arXiv:hep-ph/0210381];ibid.[arXiv:hep-ph/0110190];ibid.[arXiv:hep-ph/0006186].[15]L.Motyka and K.Zalewiski,Eur.Phys.J.C4(1998)107;ibid.,Z.Phys.C69(1996)343.[16]A.Heister et al.,(ALEPH Collaboration),Phys.Lett.B530(2002)56.[17]E.Edwards et al.,(Crystal Ball Collaborations),Phys.Rev.Lett.48(1982)70.[18]S.-K.Choi et al.,(Belle Collaboration),Phys.Rev.Lett.89(2002)102001;Erratum-ibid.89(2002)129901.[19]K.Abe et al.,(Belle Collaboration),Phys.Rev.Lett.89(2002)142001.[20]K.Hagiwara et al.,(Particle Data Group Collaboration),Phys.Rev.D66(2002)010001.[21]B.Aubert et al.,(BaBar Collaboration),[hep-ex/0311038].[22]G.Wagner,(BaBar Collaboration),[hep-ex/0305083].[23]J.Ernst et al.,(CLEO Collaboration),[hep-ex/0306060].[24]K.Abe et al.,(Belle Collaboration),Belle-Conf-0331.[25]A.A.Zholents et al.,Phys.Lett.B96(1980)214.[26]T.A.Armstrong et al.,(E760Collaboration),Phys.Rev.D47(1993)772.[27]A.M.Badalian and B.L.G.Bakker,Phys.Rev.D67(2003)071901;ibid.D62(2000)094031.[28]S.Recksiegel and Y.Sumino,Phys.Rev.D67,014004(2003).[29]S.Recksiegel and Y.Sumino,Phys.Lett.B578,369(2004).[30]S.M.Ikhdair and R.Sever,[arXiv:hep-ph/0507209](to be published).[31]T.Imbo et al.,Phys.Rev.D29(1984)1669;H.Christiansen et al.,Phys.Rev.A40(1989)1760;T.D.Imbo and U.P.Sukhatme,Phys.Rev.Lett.54(1985)2184.
