Professional (9)ForewordIn March of 2007, Dr. Wayne Blanchard of FEMA’s Emergency Management Higher Education Pro-ject, at the direction of Dr. Cortez Lawrence, Superintendent of FEMA’s Emergency Management Insti-tute, convened a working group of emergency management practitioners and academics to consider prin-ciples of emergency management. This project was prompted by the realization that while numerous books, articles and papers referred to “principles of emergency management”, nowhere in the vast array of literature on the subject was there an agreed upon definition of what these principles were.The group agreed on eight principles that will be used to guide the development of a doctrine of emer-gency management. This monograph lists these eight principles and provides a brief description of each.Members of the working group are:Dr. B.

ComprehensiveEmergency managers consider and take into account all hazards, all phases, all impacts, and all stake-holders relevant to disasters.Comprehensive emergency management can be defined as the preparation for and the carrying out of all emergency functions necessary to mitigate, prepare for, respond to, and recover from emergencies and disasters caused by all hazards, whether natural, tech-nological, or human caused. Comprehensive emer-gency management consists of four related com-ponents: all hazards, all phases, all impacts, and all stakeholders.All Hazards: All hazards within a jurisdiction must be considered as part of a thorough risk assess-ment and prioritized on the basis of impact and likeli-hood of occurrence. Treating all hazards the same in terms of planning resource allocation ultimately leads to failure. There are similarities in how one reacts to all disasters. These event-specific actions form the ba-sis for most emergency plans. However, there are also distinct differences between disaster agents that must be addressed in agent or hazard-specific plans and these can only be identified through the risk assess-ment process.All Phases: The Comprehensive Emergency Man-agement Model1 on which modern emergency man-agement is based defines four phases of emergency management: mitigation, preparedness, response, and recovery. Mitigation consists of those activities de-signed to prevent or reduce losses from disaster. It is usually considered the initial phase of emergency management, although it may be a component of other phases. Preparedness is focused on the development of plans and capabilities for effective disaster re-sponse. Response is the immediate reaction to a disas-ter. It may occur as the disaster is anticipated, as well as soon after it begins. Recovery consists of those ac-1 National Governors’ Association. 1978 Emergency Pre-paredness Project: Final Report.

Further, phases often overlap as there is often no clearly defined boundary where one phase ends and another begins. Successful emergency management coordinates activities in all four phases.All Impacts: Emergencies and disasters cut across a broad spectrum in terms of impact on infrastructure, human services, and the economy. Just as all hazards need to be considered in developing plans and proto-cols, all impacts or predictable consequences relating to those hazards must also be analyzed and addressed.All Stakeholders: This component is closely re-lated to the emergency management principles of co-ordination and collaboration. Effective emergency management requires close working relationships among all levels of government, the private sector, and the general public.2. ProgressiveEmergency managers anticipate future disasters and take preventive and preparatory measures to build disaster-resistant and disaster-resilient communities.Research and data from natural and social scien-tists indicates that disasters are becoming more fre-quent, intense, dynamic, and complex. The number of federally declared disasters has risen dramatically over recent decades. Monetary losses are rising at ex-ponential rates because more property is being put at risk. The location of communities and the construction of buildings and infrastructure have not considered potential hazards. Environmental mismanagement and a failure to develop and enforce sound building codes are producing more disasters. There is an increased risk of terrorist attacks using weapons of mass de-struction2 William L. Waugh, Jr. Living with Hazards, Dealing with Disasters: An Introduction to Emergency Management. Armonk, New York: M.E. Sharpe, 2000.Emergency management must give greater atten-tion to prevention and mitigation activities. Tradition-ally, emergency managers have confined their activi-ties to developing emergency response plans and co-ordinating the initial response to disasters. Given the escalating risks facing communities, however, emer-gency managers must become more progressive and strategic in their thinking. The role of the emergency manager can no longer be that of a technician but must evolve to that of a manager and senior policy advisor who oversees a community-wide program to address all hazards and all phases of the emergency management cycle.Emergency managers must understand how to as-sess hazards and reduce vulnerability, seek the support of public officials and support the passage of laws and the enforcement of ordinances that reduce vulner-ability. Collaborative efforts between experts and or-ganizations in the public, private and non-profit sec-tors are needed to promote disaster prevention and preparedness. Efforts such as land-use planning, envi-ronmental management, building code enforcement, planning, training, and exercises are required and must emphasize vulnerability reduction and capacity build-ing, not just compliance. Emergency management is progressive and not just reactive in orientation.3. Risk-drivenEmergency managers use sound risk management principles (hazard identification, risk analysis, and impact analysis) in assigning priorities and resources.Emergency managers are responsible for using available resources effectively and efficiently to man-age risk. That means that the setting of policy and programmatic priorities should be based upon meas-ured levels of risk to lives, property, and the environ-ment. NFPA 1600 states that emergency management programs “shall identify hazards, monitor those haz-ards, the likelihood of their occurrence, and the vul-nerability of people, property, the environment, and the entity [program] itself to those hazards”3 The Emergency Management Accreditation Program (EMAP) Standard echoes this requirement for public sector emergency management programs.3NFPA 1600 Standard on Disaster/Emergency Manage-ment and Business Continuity Programs, 2007 Edition, Na-tional Fire Protection Association, Quincy, MA. Section 5.3Effective risk management is based upon (1) the identification of the natural and man-made hazards that may have significant effect on the community or organization; (2) the analysis of those hazards based on the vulnerability of the community to determine the nature of the risks they pose; and (3) an impact analysis to determine the potential affect they may have on specific communities, organizations, and other entities. Mitigation strategies, emergency opera-tions plans, continuity of operations plans, and pre- and post-disaster recovery plans should be based upon the specific risks identified and resources should be allocated appropriately to address those risks.Communities across the United States have very different risks. It is the responsibility of emergency managers to address the risks specific to their com-munities. Budgets, human resource management deci-sions, plans, public education programs, training and exercising, and other efforts necessarily should focus on the hazards that pose the greatest risks first. An all-hazards focus ensures that plans are adaptable to a va-riety of disaster types and that, by addressing the haz-ards that pose the greatest risk, the community will be better prepared for lesser risks as well.4. IntegratedEmergency managers ensure unity of effort among all levels of government and all elements of a community.In the early 1980’s, emergency managers adopted the Integrated Emergency Management System (IEMS), an all-hazards approach to the direction, con-trol and coordination of disasters regardless of their location, size and complexity. IEMS integrates part-nerships that include all stakeholders in the commu-nity’s decision-making processes. IEMS is intended to create an organizational culture that is critical to achieving unity of effort between government, key community partners, non-governmental organizations (NGOs) and the private sector.Unity of effort is dependent on both vertical and horizontal integration. This means that at the local level, emergency programs must be integrated with other activities of government. For example, depart-ment emergency plans must be synchronized with and support the overall emergency operations plan for the community. In addition, plans at all levels of local government must ultimately be integrated with andsupport the community’s vision and be consistent with its values.Similarly, private sector continuity plans should take into account the community’s emergency opera-tions plan. Businesses are demanding greater interface with government to understand how to react to events that threaten business survival. Additionally, busi-nesses can provide significant resources during disas-ters and thus may be a critical component of the community’s emergency operations plan. In addition, given the high percentage of critical infrastructure owned by the private sector, failure to include busi-nesses in emergency programs could have grave con-sequences for the community.The local emergency management program must also be synchronized with higher-level plans and pro-grams. This is most noticeable in the dependence of local government on county, state and federal re-sources during a disaster. If plans have not been syn-chronized and integrated, resources may be delayed.Emergency management must be integrated into daily decisions, not just during times of disasters. While protecting the population is a primary responsi-bility of government, it cannot be accomplished with-out building partnerships among disciplines and across all sectors, including the private sector and the media.5. CollaborativeEmergency managers create and sustain broad and sincere relationships among individuals and organiza-tions to encourage trust, advocate a team atmosphere, build consensus, and facilitate communication.There is a difference between the terms “collabora-tion” and “coordination” and current usage often makes it difficult to distinguish between these words. Coordination refers to a process designed to ensure that functions, roles and responsibilities are identified and tasks accomplished; collaboration must be viewed as an attitude or an organizational culture that charac-terizes the degree of unity and cooperation that exists within a community. In essence, collaboration creates the environment in which coordination can function effectively.In disaster situations, the one factor that is consis-tently credited with improving the performance of a community is the degree to which there is an open and cooperative relationship among those individuals and agencies involved. Shortly after Hurricane Katrina, Governing magazine correspondent, Jonathan Walters wrote: “Most important to the strength of the inter-governmental chain are solid relationships among those who might be called upon to work together in times of high stress. ‘You don’t want to meet someone for the first time while you’re standing around in the rubble,’ says Jarrod Bernstein, a spokesman for the New York Office of Emergency Management.” 4 It is this kind of culture and relationship that collaboration is intended to establish.A commitment to collaboration makes other essen-tial roles and functions possible. Comfort and Cahill acknowledge the essential nature of collaboration within the emergency management function: “In en-vironments of high uncertainty, this quality of inter-personal trust is essential for collective action. Build-ing that trust in a multi-organizational operating envi-ronment is a complex process, perhaps the most diffi-cult task involved in creating an integrated emergency management system.”5 Thomas Drabeck6 suggests that collaboration involves three elements:1.We must commit to ensuring that we have doneeverything possible to identify all potential play-ers in a disaster event and work to involve them in every aspect of planning and preparedness for a disaster event.2.Having achieved this broad involvement, wemust constantly work to maintain and sustain the real, human, contact necessary to make the system work in a disaster event.3.Finally, our involvement of all of our “partners”must be based on a sincere desire to listen to and incorporate their concerns and ideas into our planning and preparedness efforts. This element4 Jonathan Walters. , December 1, 20055 Louise K. Comfort and Anthony G. Cahill. Managing Disaster, Strategies and Policy Perspectives. Durham, NC: Duke University Press, 19886 Thomas E. Drabek. Strategies for Coordinating Disaster Responses. Boulder, CO: Program on Environment and Behavior, Monograph 61, University of Colorado, 2003.is probably the most critical because it is this sin-cere interest that engenders trust, cooperation and understanding and allows us to truly have a “team” approach to protecting our communities in times of disaster.This principle can perhaps best be encapsulated by remembering: “If we shake hands before a disaster, we won’t have to point fingers afterwards.”76. CoordinatedEmergency managers synchronize the activities of all relevant stakeholders to achieve a common purpose.Emergency managers are seldom in a position to direct the activities of the many agencies and organi-zations involved in the emergency management pro-gram. In most cases, the people in charge of these or-ganizations are senior to the emergency manager, have direct line authority from the senior official, or are autonomous. Each stakeholder brings to the plan-ning process their own authorities, legal mandates, culture and operating missions. The principle of coor-dination requires that the emergency manager gain agreement among these disparate agencies as to a common purpose and then ensure that their independ-ent activities help to achieve this common purpose.In essence, the principle of coordination requires that the emergency manager think strategically, that he or she see the “big picture” and how each stake-holder fits into that mosaic. This type of thinking is the basis for the strategic program plan required under the National Preparedness Standard (NFPA 1600) and the Emergency Management Accreditation Program. In developing the strategic plan, the emergency man-ager facilitates the identification of agreed-upon goals and then persuades stakeholders to accept responsibil-ity for specific performance objectives. The strategic plan then becomes a mechanism for assessing pro-gram progress and accomplishments.This same process can be used on a smaller scale to develop a specific plan, such as a community re-covery plan; it is also an inherent component of tacti-7 Michael D. Selves. Oral testimony before the United States House Subcommittee on Emergency Management of the Committee on Transportation and Infrastructure, April 26, 2007. cal and operational response. The principle of coordi-nation is applicable to all four phases of the Compre-hensive Emergency Management cycle and is essen-tial for successful planning and operational activities related to the emergency management program. Ap-plication of the principle of coordination provides the emergency manager with the management tools that produce the results necessary to achieve a common purpose.7. FlexibleEmergency managers use creative and innovative ap-proaches in solving disaster challenges.Due to their diverse and varied responsibilities, emergency managers constitute one of the most flexi-ble organizational elements of government. Laws, policies and operating procedures that allow little flexibility in the performance of duties drive more tra-ditional branches of government. Emergency manag-ers are instead encouraged to developed creative solu-tions to solve problems and achieve goals.A principal role of the emergency manager is the assessment of vulnerability and risk and the develop-ment of corresponding strategies that could be used to reduce or eliminate risk. However, there can more than one potential mitigation strategy for any given risk. The emergency manager must have the flexibility to choose not only the most efficient course of action but the one that would have the most chance of being implemented.In the preparedness phase, the emergency manager uses many resources to create and maintain a well-organized community response structure. One such re-source is the development of a risk-based community emergency operations plan. While most policies and procedures in government are specific and designed to offer little room for interpretation, the emergency op-erations plan is designed to be flexible and applicable to all community emergency operations. It is based on the consequences of the event, not the promulgating action.The most dramatic phase of emergency manage-ment is response. In this phase the emergency man-ager coordinates activities to ensure overall objectives are being met. The emergency manager must be flexi-ble enough to suggest variations in tactics or proce-dures and adapt quickly to a rapidly changing and fre-quently unclear situation. The emphasis is on creative problem solving based on the event and not on rigid adherence to pre-existing plans.As part of the community team that will determine recovery priorities the emergency manager must be capable of dealing with the political, economic and social pressures in making these decisions. It is natu-ral to focus on short-term efforts in disaster recovery. However, the emergency manager cannot lose sight of the long-term needs of the community and it is this aspect of recovery that often must be driven by the emergency manager.Flexibility is a key trait of emergency management and success in the emergency management field is de-pendent upon it. Being able to provide alternate solu-tions to stakeholders and then having the flexibility to implement these solutions is a formula for success in emergency management.8. ProfessionalEmergency managers value a science and knowledge-based approach based on education, training, experi-ence, ethical practice, public stewardship and con-tinuous improvement.Professionalism in the context of the principles of emergency management pertains not to the personal attributes of the emergency manager but to a com-mitment to emergency management as a profession. A profession, as opposed to a discipline or a vocation, has certain characteristics, among which are: Code of ethics – while no single code of ethics has yet been agreed upon for the profession, the Code of Ethics of the International Association of Emergency Managers, with its emphasis on respect, commitment and professionalism, is generally accepted as the stan-dard for emergency managers.Professional associations – emergency managers seeking to advance the profession of emergency man-agement are members of professional organizations such as the National Emergency Manager’s Associa-tion (NEMA) and the International Association of Emergency Managers (IAEM). They also participate in appropriate state, local and professional associa-tions.Board certification – emergency managers seek to earn professional certification through such programs as the Certified Emergency Manager program of IAEM. Professional certification demonstrates the achievement of a minimum level of expertise and en-courages continued professional development through periodic recertification.Specialized body of knowledge– the knowledge base for emergency managers consists of three princi-pal areas. The first is the study of historical disasters, particularly as it pertains to the community for which the emergency manager is responsible. Secondly, the emergency manager must have a working familiarity with social science literature pertaining to disaster is-sues. Third, the emergency manager must be well versed in emergency management practices, standards and guidelines.Standards and best practices – the principal standards used in emergency management are NFPA 1600 and the Emergency Management Accreditation Program (EMAP) Standard. These two standards pro-vide the overarching context for the use of other stan-dards and best practices.。

And yet it can be hard to point to places where our education system is really making use of the latest neuroscience findings. But there is one happy link where research is meeting practice: bilingual education.“In the last 20 years or so, there's been a virtual explosion of research on bilingualism ,says Judith Kroll, a professor at the University of Califonia, Riverside.B) Again and again, researchers have found,“bilingualism is an experience that shapes our brain for life," in the words of Gigi Luk, an associate professor at Harvard's Graduate School of Education.At the same time, one of the hottest trends in public schooling is what's often called dual-language ortwo-way immersion programs.C) Traditional programs for English-language leamers, or ELLs, focus on assimilating students into English as quickdy as possible. Dual-languageclassrooms, by contrast, provide instruction across subjects to both English natives and English leamers, in both English and a target language.The goal is functional bilingualism and biliteracy for all students by middle school. New York City ,North Carolina, Delaware, Utah, Oregon and Washington state are among the places expanding dual-language classrooms.D) The trend fies in the face of some of the culture wars of two decades ago , when advocates insisted on“English first” education. Most famously, Califomnia passed Proposition 227 in 1998. It was intended to sharply reduce the amount of time that English-language leamers spent in bilingual settings. Proposition 58,passed by California voters on November 8, largely reversed that decision,paving the way for a huge expansion of bilingual education in the state that has the largest population of English-language leamers.E) Some of the insistence on Englih-first was founded on research produced decades ago, in which bilingual students underperformned monolingual English speakers and had lower IQ scores. Today's scholars, like Elen Bialystok at York University in Toronto, say that research was “deeply flawed. ”“ Earlier research looked at socially disadvantaged groups, ”agrees Antonella Sorace at the University of Edinburgh in Scotland.“This has been completely contradicted by recent research'”that compares groups more similar to each other.F) So what does recent research say about the potential benefts of bilingual education? It tuns out that, in many ways, the real trick to speaking twolanguages consists in managing not to speak one of those languages at a given moment- -which is fundametally a feat of paying attention. Saying “Goodbye" to mom and then“Guten t ag" to your teacher, or managing to askfor a crayola roja instead of a red crayon, requires skills called “ inhibition”and “task switching.” These skills are subsets of an ability called executive function.G) People who speak two languages often outperform monolinguals on general measures of executive function.“ Bilinguals can pay focused attention without being distracted and also improve in the ability to switch from one task to another,”says Sorace.H) Do these same advantages beneft a child who begins learning a second language in kindergarten instead of as a baby? We don't yet know. Patterns of language learning and language. use are complex. But Gigi Luk at Harvard cites at least one brain-imaging study on adolescents that shows similar changes in brain structure when compared with those who are bilingual from bith, even when they didn't begin practicing a second language in eamest before late childhood.I) Young children being raised bilingual have to follow social cues to fngure out which language to use with which person and in what setting. As a result, says Sorace,bilingual children as young as age 3 have demonstrated a head start on tests of perspective-taking and theory of mind- -both of which are fundamental social and emotional skills.J) About 10 percent of students in the Portland, Oregon public schools are assigned by lottery to dua]-language classrooms that offer instruction in Spanish, Japanese or Mandarin, alongside English.Jennifer Steele at American University conducted a four-year, randomized trial and found that these dual-language students outperforned their peers in English-reading skills by a full school-year's worth of learning by the end of middle school. Because the effects are found in reading, not in math or science where there were few differences, Steele suggests that learning two languages makes students more aware of how language works in general.K) The research of Gigi Luk at Harvard offers a slightly different explanation. She has recently done a small study looking at a group of 100 fourth-graders in Massachusetts who had similar reading scores on a standard test, but very different language experiences. Some were foreign-language dominant and others were English natives. Here's what's interesting. The students who were dominant in a foreign language weren't yet comfortably bilingual; they were just starting to leam English.Therefore, by definition, they had a much weaker English vocabulary than the native speakers.Yet they were just as good at interpreting a text. “ This is very surprising," Luk says.“You would expect the reading comprehension performance to mirror the vocabulary- -it's a cormerstone of comprehension.*L) How did the foreign-language dominant speakers manage this feat? Well, Luk found, they also scored higher on tests of executive functioning. So, even though they didn't have huge mental dictionaries to draw on, they may havebeen great puzzle- solvers, taling into account higher-level concepts such as whether a single sentence made sense within an overall story line. They got to the same results as the monolinguals, by a different path.M) American public school classrooms as a whole are becoming more segregated by race and class.Dual-language programs can be an exception.Because they are composed of native English speakers deliberately placed together with recent immigrants, they tend to be more ethnically andeconomically balanced. And there is some evidence that this helps kids of all backgrounds gain comfort with diversity and different cultures.N) Several of the researchers also pointed out that, in bilingual education, non-English- dominant students and their families tend to feel that their home language is heard and valued,compared with a classroom where the home language is left at the door in favor of English. This can improve students' sense of belonging and increase parents' involvement in their children's education,including behaviors like reading to children. “ Many parents fear their language is an obstacle,a problem, and if they abandon it their child will integrate better," says Antonella Sorace of the University of Edinburgh.“We tell them they're not doing their child a favor by giving up their language.”O) One theme that was striking in speaking to all these researchers was just how strongly they advocated for dual-language classrooms. Thomas and Collier have advised many school systems on how to expand theirdual-language programs, and Sorace runs “ Bilingualism Matters," aintermational network of researchers who promote bilingual education projects. This type 0 advocacy among scientists is unusual; even more so becausethe“bilingual advantage hypothesis" is being challenged once again.P) A review of studies published last year found that cognitive advantages failed to appear in 83 percent of published studies , though in a separateanalysis , the sum of effects was still signifcantly positive.One potential explanation offered by the researchers is that advantages that are measurable in the very young and very old tend to fade when testing young adults at the peak of their cognitive powers. And, they countered that no negative effects of bilingual education have been found.So,even if the advantages are small, they are still worth it. Not to mention one obvious, outstanding fact:“ Bilingual children can speak two languages! ' '36. A study found that there are similar changes in brain structure betweenthose who are bilingual from birth and those who start leaming a secondlanguage later.37. Unlike traditional monolingual prograns, bilingual classrooms aim atdeveloping students' ability to use two languages by middle school.38. A study showed that dual-language students did significantly better thantheir peers in reading English texts.39. About twenty years ago, bilingual practice was strongly discouraged,especially in California.10. Ethnically and economically balanced bilingual classooms are found to be helpful for kids to get used to social and cultural diversity.41. Researchers now claim that earlier research on bilingual education was seriously flawed.42. According to a researcher , dual-language experiences exert a lifelong influence on one's brain.43. Advocates of bilingual education argued that it produces positive effects though they may be limited.44. Bilingual speakers often do better than monolinguals in completing certain tasks because they can concentrate better on what they are doing.45. When their native language is used, parents can become more involved in their children's education.Passage OneQuestions 46 to 50 are based on the following passage.It is not controversial to say that an unhealthy diet causes bad health. Nor are the basic elements of healthy eating disputed. Obesity raises susceptibility tocancer, and Britain is the sixth most obese country on Earth. That is a public health emergency. But naming the problem is the easy part. No one disputesthe costs in quality of life and depleted health budgets of an obese population, but the quest for solutions gets diverted by ideological arguments aroundresponsibility and choice. And the water is muddied by lobbying from the industries that profit from consumption of obesity-inducing products.Historical precedent suggests that science and politics can overcome resistance from businesses that pollute and poison but it takes time, andsuccess often starts small. So it is heartening to note that a programme inLeeds has achieved a reduction in childhood obesity, becoming the first UK city to reverse a fattening trend. The best results were among younger children and in more deprived areas.When 28% of English children aged two to 15 are obese, a national shift on the scale achieved by Leeds would lengthen hundreds of thousands of lives. A significant factor in the Leeds experience appears to be a scheme called HENRY,which helps parents reward behaviours that preyent obesity in children.Many members of parliament are uncomfortable even with their own govemment's anti-obesity strategy,since it involves a“sugar tax" and a ban on the sale of energy drinks to under-16s. Bans and taxes can be blunt instruments, but their harshest critics can rarely suggest better methods.These critics just oppose regulation itself.The relationship between poor health and inequality is too pronounced for govermments to be passive about large-scale intervention. People living in the most deprived areas are four times more prone to die from avoidable causes than counterparts in more affluent places. As the structural nature of publichealth problems becomes harder to ignore,the complaint about overprotective govenment loses potency.In fact, the polarised debate over public health interventions should have been abandoned long emment action works when individuals are motivatedto respond. Individuals need govemments that expand access to good choices.The HENRY programme was delivered in part through children's centres. Closing such centres and cutting council budgets doesn't magically increase reserves of individual self-reliance. The function of a well-designed state intervention is not to deprive people of liberty but to build social capacity and infrastructure that helps people take responsibility for their wellbeing. The obesity crisis will not have a solution devised by leit or right ideology- -but experience indicates that the private sector needs the incentive of regulation before it starls taling public health emergencies seriously.46. Why is the obesity problem in Britain so difficult to solve?A) Goverment health budgets are depleted.B) People disagree as to who should do what.C) Individuals are not ready to take their responsibilties.D) Industry lobbying makes it hard to get healthy foods.47. What can we learmn from the past experience in tacking public health emergencies?A) Govemments have a role to play.B) Public health is a scientifc issue.C) Priority should be given to deprived regions.D) Businesses' responsility should be stressed.48. What does the author imply about some critics of bans and taxes concerning unhealthy drinks?A) They are not aware of the consequences of obesity.B) They have not come up with anything more constructive.C) They are uncomfortable with parliament's anti obesity debate.D) They have their own motives in opposing govermment regulation.49. Why does the author stress the relationship between poor health and inequality?A) To demonstrate the dilemma of people living in deprived areas.B) To bring to light the root cause of widespread obesity in Britain.C) To highlight the area deserving the most attention from the public.D) To justify govermment intervention in solving the obesity problem.50. When will govermment action be effective?A) When the polarised debate is abandoned.B) When ideological differences are resolved.C) When individuals have the incentive to act accordingly.D) When the private sector realises the severity of the crisis.Passage TwoQuestions 51 to 55 are based on the following passage.Home to virgin reefs, rare sharks and vast numbers of exotic fish, the Coral Sea is a unique haven of biodiversity off the northeastem coast of Australia. If a proposal by the Australian govemment goes ahead, the region will also become the world's largest marine protected area, with restrictions or bans on fishing, mining and marine farming.The Coral Sea reserve would cover almost 990 000 square kilometres and stretch as far as 1100 kilometres from the coast. Unveiled recently by environment minister Tony Burke,the proposal would be the last in a series of proposed marine reserves around Australia's coast.But the scheme is attracting criticism from scientists and conservation groups,who argue that the govemment hasn't gone far enough in protecting the Coral Sea, or in other marine reserves in the coastal network.HughPossingham,director of the Centre of Excellence for Environmental Decisions at the University of Queensland, points out that little more than half of the CoralSea reserve is proposed as“no take" area, in which all fishing would be banned. The world's largest existing marine reserve,established last year by the British govemment in the Indian Ocean, spans 554 000 km2 and is a no-take zone throughout. An alliance of campaigning conversation groups argues that more of the Coral Sea should receive this level of protection.“I would like to have seen more protection f or coral reefs," says Tery Hughes, director of the Centre of Excellence for Coral Reef Studies at James CookUniversity in Queensland.“More than 20 of them would be outside the no-take area and vulnerable to catch- and-release fshing” .As Nature went to press, the Australian govemment had not responded to specifc criticisms of the plan. But Robin Beaman, a marine geologist at James Cook University, says that the reserve does“broadly protect the range of habitats”in the sea.“I can testify to the huge effort that govemment agencies and other organisations have put into trying to understand the ecological values of this vast area," he says. .Reserves proposed earlier this year for Australia's southwester and northwesterm coastal regions have also been criticised for failing to give habitats adequate protection. In August,173 marine scientists signed an open letter to the govemment saying they were“greatly concemed" that the proposals for the southwestem region had not been based on the“ core science principles”of reserves-the protected regions were not, for instance , representative of all the habitats in the region, they said.Critics say that the southwestem reserve offers the greatest protection to the offishore areas where commercial opportunities are fewest and where there is lttle threat to the environment,a contention also levelled at the Coral Sea plan.51. What do we learn from the passage about the Coral Sea?A) It is exceptionally rich in marine life.B) It is the biggest marine protected area.C) It remains largely undisturbed by humans.D) It is a unique haven of endangered species.52. What does the Australian govemment plan to do according to Tony Burke?A) Make a new proposal to protect the Coral Sea.B) Revise its conservation plan owing to criticisms.C) Upgrade the established reserves to protect marine life.D) Complete the series of marine reserves around its coast.53. What is scientists' argument about the Coral Sea proposal?A) The govemment has not done enough for marine protection.B) It will not improve the marine reserves along Australia's coast.C) The govemment has not consulted them in drawing up the proposal.D) It is not based on suffcient investigations into the ecological system.54. What does marine geologist Robin Beaman say about the Coral Sea plan?A) It can compare with the British govemment's effort in the Indian Ocean.B) It will result in the establishment of the world's largest marine reserve.C) It will ensure the sustainability of the fishing industry around the coast.D) It is a tremendous joint effort to protect the range of marine habitats.55. What do critics think of the Coral Sea plan?A) It will do more harm than good to the environment.B) It will adversely affect Australia's fishing industry.C) It will protect regions that actually require lttle protection.D) It will win lttle support from environmental organisations.Part IV Translation(30 minutes)Directions: For this part, you are allonwed 30 minutes to translate a passage from Chinese into English.

英美关于职位、职称的称呼一、教授体系(一)美国教授体系美国的教授体制,显著的特点就是终身教授制度(tenure)。
一般能晋升为副教授,即意味着拿到了终身教职,也就意味着以后不会因学术考核而被学校解聘了。
美国的教授职称,分为教学研究型和纯研究型职称。
前者类似国内的教授体系,后者类似于研究员体系。
美国教授的教学研究型职称,主要包括四个阶段:1. 助理教授(assistant professor)。
助理教授一般是三到六年的试用期。
试用期后,如果工作出色,经过评选可以晋升为拥有终身教职的副教授。
否则,卷铺盖走人。
目前随着博士毕业生的数量增加,而全美的助理教授岗位有限,因此助理教授职位的竞争也日益激烈。
于是,出现了获得博士学位后,需要经历多站的博士后研究,方能达到一定的学术能力,去应聘助理教授的职位。
到此时,平均年龄差不多35岁上下了。
大约有一般的助理教授最终能够获得终身教职,不过在一些顶尖大学里,这个比例可能低至10%。
因此,在助理教授期间,是工作科研最为拼命的时候,也是学术论文的高产期。
经过这么六年左右的“煎熬”,很多人的头发都会逐渐变白,以及明显的掉发,甚至秃顶。
漫步在美国一流大学里,碰见的研究人员大多十有八九头发变白即是此理。
如果拿到终身教职的人,头发依旧乌黑,不外乎两种可能:一是染发了,二是该学者是出奇地厉害,可能二十出头就完成了科研及学术论文的积累,早早过了助理教授这个阶段。
2. 副教授(associate professor)。
经过那水生火热的六年左右助理教授期,如果成功获得终身教职,那么可以晋升为副教授。
评判标准一般都是在助理教授期间有大量的学术成就,比如发表了影响力较大的专著,以及大量的学术论文,拿到了研究项目,对所在部门有突出的教学或服务。
该评判标准又因所在学校不同,所要求的标准和严格程度也不同。
一般副教授都是终身教职。
但是,也有人以副教授职位进行聘请后还没有终身职位的,这一般是从外部引入的人才。
梅河口市第五中学2023-2024学年高二下学期开学考试英语试卷学校:___________姓名:___________班级:___________考号:___________一、阅读理解Bristol Old VicWhen the Theatre Royal (now Bristol Old Vic) was built, electricity hadn’t been discovered. For over 250 years the people who have owned, worked inside and visited the theatre have kept records about their activity. These are kept safe at the University of Bristol Theatre Collection, and you’ll discover a range of documents which record the history of the theatre, from its foundation in 1764 up until the present day. Here are some of them. BEGINNINGIn 1764 businessmen Alexander Edgar and Thomas Symons suggested building a new theatre between Baldwin Street and the back of Coopers’ Hall in King Street. The estimated cost was f2, 000 to be split among 40 subscribers, but the building work cost more than expected. Owning shares allowed them to influence decisions about the theatre.SILVER TICKETEach of the original Bristol Old Vic shareholders was given a silver ticket that promised sight of any performance held at the theatre. As the holders were clever businessmen, they insisted that the silver tickets could be loaned or traded. This enabled them to make some extra money but made it extremely difficult for the theatre managers to keep track of who was allowed to see shows for free.250TH BIRTHDAYIn May 2016, the theatre celebrated its 250th birthday! As the oldest continuously-working theatre in the English-speaking world, it deserved a proper party, so Bristol-based Limbic Cinema was hired to create a film of the theatre’s historical highlights which was projected (放映) onto the theatre itself.1.Where can you find the three mentioned documents?A. At Baldwin Street.B. At Coopers’ Hall in King Street.C. At Bristol-based Limbic Cinema.D. At the University of Bristol Theatre Collection.2.How was the theatre’s 250th birthday celebrated?A. By creating a film about its history.B. By building Bristol-based Limbic Cinema.C. By releasing silver ticket in memory of the birthday.D. By making a film projected in theatres across England.3.What’s the purpose of the text?A. To compare the theatre and others.B. To change people’s view on Bristol Old Vic.C. To introduce some information of Bristol Old Vic.D. To recommend a movie related to the theatre.For many runners, a marathon can often be a challenge — but sometimes what gets a runner through the tough 26.2 miles is looking out into the crowd and seeing his or her loved one holding up a sign and shouting words of encouragement. For one mom, though, her loved one was a bit more hands-on.While running the REVEL Big Cottonwood Marathon in Salt Lake City, Courtney Rich, a self-taught baker and mother of two, was beginning to run out of energy just yards from the end when she was suddenly joined by her 10-year-old daughter, Avery.The touching moment, caught on video and posted on social media, shows Avery running to her mother’s side to support her as she approached the end of the race. Rich’s face lit up when Avery joined her and helped her cross the finish line.Rich later said in the video’s caption that being joined by her daughter to finish the race was “a moment I hope neither of us ever forget”. Rich said that her daughter could tell she was struggling after a phone call near the end of the race. “She knew I had struggled the last few miles,” Rich said. “She saw tears in my eyes when I called on mile 24.”In the video, Rich’s facial expression changes from tiredness to a smile after seeing her daughter emerge from the crowd to join her. Then, Rich and her daughter ran hand-in-hand to the finish line. “Nothing could have prepared me for the moment my 10-year-old daughter would jump out of the crowd and run with me to the finish line,” she said. When the race was done, the two hugged each other at the finish line. The video ends with a final caption, “And then she just held me. She held me.”In the past, the REVEL Big Cottonwood Marathon has had other memorable moments of mothers caring for their children, but perhaps not as hands-on as this one.4.What happened to Rich when she was coming to the finish line?A. She fell down all of a sudden.B. She was far behind others.C. She felt herself struggling.D. She was interrupted by Avery.5.How did Avery react to the accident?A. She helped Rich run to the finish line.B. She tried to call for help at once.C. She ran the rest in place of Rich.D. She shouted encouraging words to Rich.6.How did Rich feel about Avery’s response?A. Doubtful.B. Content.C. Concerned.D. Expected.7.What can be the best title for the text?A. A Mother Would Never Give Up On Her Marathon DreamB. A Mother Encouraged Her Daughter To Pursue Her DreamC. A Daughter Got Involved In Her Mother’s Race By MistakeD. A Daughter Cheered For Her Mother By Joining In Her RaceWithin the beautiful scenery of Wisconsin’s Lake Chippewa lies a natural wonder that is a unique challenge for the local community. This hidden wonder is exactly a giant floating island. The island, made up of plants and trees, sometimes floats around the lake, causing a major inconvenience by blocking (阻塞) an important bridge. Later, the local people came up with a solution to this problem. Every year, local boat owners work together and push the island away from the bridge.Lake Chippewa was born in 1923 when a vast bog (沼泽) was changed through flooding. Soon after that, many of the dark bogs started rising to the surface and became perfect growing places for plants, with seeds carried by wind and wild birds to this floating place. Over the years, these bogs have grown plants and trees and turned into full islands. As time goes by, plants take root, and the oldest islands even have trees that act as sails (船帆) when the wind blows, moving the entire floating island around the lake.Although the years-old floating island does not relocate (重新迁移) so often, when it does, it causes trouble for the community by blocking the important bridge that serves as the only passage between the lake’s East and West sides. The only solution is to gather a group of boats, and not just one or two, but dozens of boats working together to push the island away. “It takes a community’s effort, and you must have the winds at your back to push them in,” said a resident. Moving the island also requires precision (精确), as just relocating it a short distance may result in its return within days.Some people have suggested destroying the floating islands to get rid of the problem. However, the big bog in Lake Chippewa has been around for many years, and during thattime a variety of animal and plant species have made it their home. Therefore, local government advises they be dealt with in a way that won’t do harm to wildlife, paying more attention to the fine-drawn balance between human convenience and environmental protection. The annual tradition of relocating Lake Chippewa’s floating island is evidence to the coexistence of man and nature, a heartwarming display of community unity, and a reminder of the importance of preserving the unique areas that enrich our world.8.What does the underlined word “solution” in paragraph 1 refer to?A. Building a new bridge.B. Moving the floating island away.C. Transforming the vast bog.D. Rebuilding the local community.9.What can we know from paragraph 2?A. The formation of the floating island.B. The history of flooding in Lake Chippewa.C. The varieties of species in Lake Chippewa.D. The impact of the wind on the floating island.10.Which of the following statements is true about the relocation work from paragraph 3?A. It is usually finished within days.B. It is a must in cooperation and precision.C. It can only be carried out during windless days.D. It greatly disturbs the community residents’ lives.11.Why has the local government refused to destroy the island?A. To save costs for local people.B. To ensure the safety of residents.C. To improve the bond between communities.D. To protect the wildlife species on the island.Like so many other good things in life, sleep is best at a right length. A multi-year study of older adults found that both short and long sleepers experienced greater cognitive (认知的) decline than people who slept a proper amount, even when the effects of early Alzheimer's disease were taken into account.“Our study suggests that there is a middle range, or ‘sweet spot’, for total sleep time where cognitive performance is stable over time. Short and long sleep time is associated with worse cognitive performance,” said first author Brendan Lucey, an associate professor of the Washington University Sleep Medicine Center. “An unanswered question is if we can intervene to improve sleep, would that have a positive effect on their cognitive performanceso they no longer decline? We need more further data to answer this question.”Lucey and colleagues turned to volunteers who participate in Alzheimer's studies through the university's Charles F. and Joanne Knight Alzheimer Disease Research Center. Such volunteers experienced annual clinical and cognitive assessments, and provided a blood sample to be tested. For this study, each participant slept with a tiny EEG monitor attached to their heads for four to six nights to measure their brain activities during sleep.The researchers found a U-shaped relationship between sleep and cognitive decline. Overall, cognitive scores declined for the groups that slept less than 4.5 or more than 6.5 hours per night while scores stayed stable for those in the middle of the range.The U-shaped relationship held true for measures of specific sleep phases, including rapid-eye movement (REM), or dreaming sleep and non-REM sleep. Moreover, the same is true even after adjusting for factors that can affect both sleep and cognition, such as age, sex, levels of Alzheimer's proteins. “It was particularly interesting to see that not only those with short amounts of sleep but also those with long amounts of sleep had more cognitive decline,” said Professor Be au M. Ances.“Each person's sleep needs are unique, and people who wake up feeling rested on short or long sleep schedules should not feel forced to change their habits,” said co-senior author David Holtzman, MD. “But those who are not sleeping well should be aware that sleep problems often can be treated.”12.What's the passage mainly about?A. The effects of Alzheimer's disease.B. The benefits of best sleep.C. The influence of sleep time on cognition.D. The good things in life.13.According to the passage, which sleep time is suitable?A. 4 hours.B. 6 hours.C. 7 hours.D. 7. 5 hours.14.What can we know about U-shaped relationship?A. The sleep time has no connection with cognitive scores.B. The longer sleep time is, the higher cognitive scores are.C. Cognition is related to different sleep phases.D. It is not effective when age, sex, and so on are considered.15.What does David Holtzman's words imply?A. Quality of sleep is the key.B. Long time sleepers do not have cognitive decline.C. Short sleep schedules must change their habits.D. Both long time and shot time sleepers have sleep problems.二、七选五16.When gardeners grow varieties of plants in their beautiful gardens, they are happy to see beneficial insects like bees and butterflies surrounding the flowers. But as they take a closer look, they may find some plants are covered in black dots and filled with harmful insects or pests. Some gardeners may immediately reach for chemicals. ①_________ Although it may stop the insect problem, it will also threaten bees and butterflies which help the plants reproduce.If you are wise gardeners, you should first take preventive measures to control the harmful insects. ② _________ Only when there are too many harmful insects, should pest control be considered. The first defense should always be the safest method available. PreventionAs a rule, prevention is the best treatment.

RESEARCHThe Medical Journal of Australia ISSN:0025-729X 4 August 2003 179 3 130-133©The Medical Journal of Australia .au Research A S THE A USTRALIAN POPULATION ages, changes in the distribution of disa-bility and morbidity will lead to changes in healthcare needs and costs of care for older people.1,2 To appropriately planhealth services we need reliable projec-tions of disability in both the entire population and in older people.The most recent (1998) national Sur-vey of Disability, Ageing and Carers (SDAC) in 1998 by the Australian Bureau of Statistics (ABS) estimated that 3.6 million Australians (19%) had some form of disability.3 Of these, 2.8million (78%) had a core activity restriction — in self-care, mobility or communication — caused by their disa-bility.4 The ABS further defines core activity restrictions as profound, severe,moderate or mild.3 People with a pro-found restriction are unable to perform a core activity, such as eating or dress-ing, or always require assistance from another person. People with severe restriction sometimes need assistance to perform a core activity, while those with moderate restriction do not need assist-ance but have difficulty performing a core activity. People with mild restric-tion use aids because of their disability,but have no difficulty in performing a core activity.The Australian Institute of Health and Welfare 5 has recently presented projections of the numbers of people with either profound or severe core activity restrictions for the years 2000–2031, based on the disability preva-lences in the SDAC.3 However, the main health conditions underlying disa-bility were not considered.Our aim was to provide detailed pop-ulation projections for disability and the common health conditions underlyingdisability in older people for the period 2006–2031. Our study is a secondary analysis of data collected by the ABS and extends the work done by the Aus-tralian Institute of Health and Welfare.5METHODSABS population projections for 2006 to 2031 were taken from the most recently published series.6 We used the ABS projection Series I, II and III to com-pare the projections of disability with a range of assumptions for fertility, migra-tion and mortality. All three series assume life expectancy at birth will increase over the projection period.Series II most closely reflects current fertility and migration levels. Series I (high population growth) and III (lowpopulation growth) are presented to contrast the results obtained from the medium series for the percentage change in disability. We also used the 1998 ABS Survey of Disability, Ageing and Carers Confidentialised Unit Record File 7 to derive estimates of the prevalence of disability and selected main health conditions associated with disability. Some additional data break-downs for the oldest age groups (ie, 85–94 and 95+) were provided by the ABS.Established procedures 5,8 were used to derive projections of disability:■Data from the 1998 SDAC were used to derive age-group and sex-spe-cific prevalence rates of (i) disability and (ii) underlying health conditions;■These rates were applied to the pro-jected 2006–2031 age and sex distribu-tions of the Australian population,using Series I, II and III from the ABS projections.RESULTSThe prevalence of disability by category of core activity restriction in 1998 is summarised in Box 1.

The main conditions associated with profound or severe core activity restriction in older Australians are musculoskeletal, nervous system, circulatory and respiratory conditions and stroke.Conclusions: In the future, there will be many more older Australians requiring assistance because of disability. This will present a challenge to families, friends, volunteers and paid service providers. The Australian planning ratio for residential aged-care services and community aged care services should be changed to take MJA 2003; 179: 130–133account of the shift to an older population with greater need of support.Department of Rehabilitation and Aged Care, Flinders University, Adelaide, SA.Lynne C Giles, MPH, AStat, Clinical Epidemiologist and Research Manager; Maria Crotty, PhD, FAFRM (RACP), Professor, and Head.Rehabilitation Studies Unit, Faculty of Medicine, University of Sydney, Sydney, NSW.Ian D Cameron, PhD, FAFRM (RACP), AssociateProfessor, and Head.Reprints will not be available from the authors.

While peo-ple with disability who require assist-ance often obtain this assistance from informal providers, more than 50% of older people also receive formal paid assistance.4 Our projections imply that there will be a greater need for both informal and formal assistance.The current planning ratio for resi-dential aged-care services, based only on the population over 70 years of age, will become progressively more inequi-table, because the age-specific preva-lence of profound disability (associated with a need for residential care) increases from about 5% at age 70 years to 50% at age 90 years. In other coun-tries with ageing populations (eg, Ger-many and Japan), the response has been to introduce insurance for long-term care, and such approaches need to be debated. The Australian planning ratio for residential aged care services and community aged care packages should be changed to take account of the shift to an older population with greater sup-port needs.There are difficulties associated with collecting data by self-report — the method used for determining the main conditions underlying disability in the SDAC. For example, nervous system disorders (including “Alzheimer’s dis-ease” and “dementia”) were reported as the main condition underlying disability by around 16% in the 85 years and older group. Estimates of the point prevalence of dementia alone in this age group using DSM-III-R criteria11 have varied between 21% and 30%.12,13 This raises the question of whether self-report is the best method for these surveys.Another potential limitation is that surveys such as the SDAC combine transient disability (such as that associ-ated with a fall) and chronic disability (such as that associated with dementia) and assume that disability is a static rather than dynamic attribute. Longitu-dinal studies14,15 identify older individu-als who recover from disability and show that their condition does not nec-essarily deteriorate.16There has been debate about the trends in disability with ageing. Data from the 1980s and 1990s have shown increases in the period of disability-freelife.14,17 For example, the prevalence ofchronic disability in older people in theUnited States was shown to havedeclined by 0.47% per annum over thepast decade.18 If a similar trendoccurred in Australia over the next 30years, then the disability prevalence onwhich our projections are based woulddecrease from about 54% in 1998 (Box 1[value weighted by the estimated popu-lation in each age group]) to 38.5% ofolder Australians in 2031. In absolutenumbers this would still represent 2.1million people with a disability, which isfar in excess of the comparable 1998figure of 1.2 million people. However,analyses by the Australian Institute ofHealth and Welfare5 suggest that short-term changes in disability prevalence inAustralia do not follow the reported UStrend. Moreover, its analyses show thatdisability prevalence in persons aged 65years and older may have increased by0.2% per year from 1981 to 1998.5Some caution must be exercised wheninterpreting our projections. The ABSpopulation projections are based on cur-rent knowledge, and our estimates ofdisability prevalence were based on 1998data. Thus, our projections are likely tobe robust if the assumptions regardingmortality, migration and fertility under-pinning the population projections holdin the future, and the prevalence ofdisability remains constant. We repeatedall analyses using the three projectionseries and very similar estimates werederived from each series, lending confi-dence to our findings.It may be possible to reduce the pro-jected increase in profound disabilitylate in life. There is evidence that treat-ing chronic health impairments (eg,self-management approaches for arthri-tis and diabetes) prevents disability.Environmental risks for disability,including social support, health systemfactors, and community support inter-ventions, are a neglected and crucialarea.19 There is an urgent need thattranscends organisational boundaries todevelop effective approaches to deliver-ing care and maintaining older people inthe community.Even if the projected increase in totalprevalence of disability can be mitigated,a greater number of older Australians inthe future will have a disability, andmany will require assistance.COMPETING INTERESTSNone identified.REFERENCES1.Fried LP, Bush TL.

Four Measures of System BehaviorDavid Kazmer Associate ProfessorDavid HatchResearch AssistantLiang ZhuResearch AssistantDepartment of Mechanical & Industrial EngineeringUniversity of Massachusetts AmherstAbstractEngineering systems are typically designed to cost and specification. The robustness of the engineered systems is frequently measured with respect to consistency according to a Six Sigma philosophy. However, robustness is just one measure of system behavior, and in insufficient to characterize the behavior of complex systems with respect to extensibility, robustness controllability, and flexibility. The extensibility index measures the extent to which the quality attributes may be adjusted relative to their variation, even if such adjustment causes other attributes to fail specification. The robustness index is representative of consistency of the quality attributes, as measured the relative breadth of the specification to the variance of the quality attributes. The controllability index measures the span of the quality attributes while maintaining the feasibility of the other quality attributes. Finally, the flexibility index measures the range of the quality attributes while holding other quality attributes fixed. All of the measures are valid for linear and non-linear systems, uncoupled and coupled systems, and systems with varying number of decision variables and quality attributes. The four measures are applied to the injection molding of digital video disc substrates. The application example demonstrates some significant short comings in this manufacturing process, and provides insight into general system design requirements and strategies.IntroductionEngineering design is an unstructured but logic-based process where successive iterations of synthesis and analysis eventually converge to the desired solution [Paz-Soldan, 1989 #701]. This iterative process is necessary since it is normally infeasible to deduce the final design from the initial set of specifications.There are many difficulties in the design process that prevent direct convergence to a final design. First, there are many potential concept strategies that may result in an adequate solution. The development and validation of each design concept requires the configuration of the components within the engineered system and identification of the design parameters. If the approach appears promising, quantitative relationships may be established between the design parameters and performance attributes. These relationships can be complex and numerous such that the designer may not be able to simultaneously navigate and resolve an adequate solution. At this stage, the designer may become acutely aware of difficulties with the design: inadequate performance, conflicting specifications, and infeasibility. The designer may accept the current design as final, modify the design parameters to negotiate between the different performance attributes, consider the relaxation or constriction of the design specifications, or start again with another concept design. This complex decision-making process prevents direct development of the final design in all but incremental redesigns.In the context of this article, a system is defined by a set of relations between quality attributes, y i , that are dependent upon the selection of the decision variables, x j . For a system design to be feasible, a set of decision variables must be selected within their lower and upper control limits, i.e. LCL j ≤ x j ≤ UCL j , such that each of the quality attributes is within their lower and upper specification limits, i.e. LSL i ≤ y i ≤ USL i . While the relationship between decision variables and quality attributes is frequently presented via the function matrix, A :[]XY=, (0)Athere is no requirement in engineering design that a linear mapping exist from the decision variablesto quality attributes, nor that the function matrix, A, is square.TheoryRecent research in both industry and academe has focused on achieving robustness in systemdesign (Iyer and Krishnamurty 1998; Koch and Mavris 1998; Suri and Otto 1999; Thornton 1999;Zhang, Wiecek et al. 1999). While many of the academic approaches do provide significant insightinto the behavior and optimality of systems, they very frequently require information and numericalmethods that are beyond the capability of the research team that published the work. Alternatively,industry practitioners frequently rely on overly simplified approaches that require little informationand no or minimal optimization. However, such overly simplified approaches often produceincorrect results, or overly focus on non-critical issues. Robust design is not the only, and perhapsnot even the most important, aspect of system design.Towards this end, four measures of system behavior are defined: robustness, extensibility,controllability, and flexibility. Robustness will first be defined since it may be best understood due tosignificant emphasis of Six Sigma in the media. Special attention has been paid to ensure thepotential for broad adoption. As such, the only required information is the function matrix, controllimits, specification limits, and standard deviations of the quality attributes. All results of this papercan be reproduced with simple single objective, constrained optimization techniques.RobustnessRobustness has been defined as the insensitivity of performance to uncontrolled variation. Lackof system robustness can lead to unsatisfactory product performance, low production yields, andincreased operating cost in end use. The Six Sigma philosophy (Breyfogle 1999) dictates that themean performance should be located six standard deviations from the closest performancespecification. In engineering practice, application of Six Sigma implies a defect rate less than three defects per million. However, it is well known among researchers that normal statistics are rarely valid to this degree of precision (Ref), and that such application is very prone to uncertainty in models and insufficiency of assumptions (Roser and Kazmer 2001).Rather, the original motivation of the Six Sigma methodology was to ensure a production yield of 99.87% in 99.87% of the applications. As shown in Figure 1, the mean performance should be located at least three standard deviations from the nearest specification limit. To allow for long-term shifts in the mean performance, the targeted mean performance should be another three standard deviations from the allowable mean performance. Together, six standard deviations should be required between the targeted mean performance and the closest specification limit.Figure 1: Six Sigma PhilosophyFrequently, a process capability index, Cp ,σ6LSL USL Cp −= (1) or the asymmetric process capability index, Cpk ,⎟⎠⎞⎜⎝⎛−−=σµσµ3,3min LSL USL Cpk (2)is utilized as a measure of robustness (Boyles 1991). The Cpk index has two advantageous properties: 1) that it can be used for one sided metrics, and 2) denotes a loss in quality due to shifts of the mean off the target center. In either case, however, a process capability equal to one generally implies product performance at the target level with three standard deviations to the closest specification limit. The process capability should be at least two to meet Six Sigma guidelines.Most engineering systems, however, have multiple quality attributes. As such, it is desirable to measure the robustness of the individual quality attributes as the aggregate system. The robustness, Ri, of each quality attribute can be computed directly as the process capability index of eq. (1) and(2), where the USL , LSL , µ, and σ, are appropriately substituted for each quality attribute. If the mean, µ, and standard deviation, σ, are unknown, then the process capability index of eq. (1) is frequently used with an estimate of σ derived from a moment matching formula (Cacoullos 1982). It has been proposed (Ford 1996; Kazmer 1999) that the robustness of a system with multiple quality attributes may be evaluated via the joint probability of likely acceptance as:(3) i n i system P P 1=Π=where i P i i ∀⋅Φ−=ℜ−131 (4) which is also valid for the relation between √system and P system . Combining these equations gives: ()()attributes quality of Number functiondensity cumulative normal Inverse functiondensity cumulative Normal (1) eq. attribute,quality th -i of Robustness :where ,321212131111≡≡Φ≡Φ≡ℜ⎟⎠⎞⎜⎝⎛ℜ−Φ−−Φ−=ℜ−=−Πn i i n i (5)Thus, system robustness is an aggregate performance measure that includes the likelihood of each quality attribute being acceptable. It is important to note that internal validation has shown thatthe independence assumption is not generally valid, as will be discussed in more detail later on. However, this measure generally provides a reasonable estimate of system robustness, and does possess several beneficial properties useful in system design including (Kazmer 1999): 1) models multiple design objectives; 2) convex behavior allows for global optimization; 3) allows for direct inclusion of different kinds of specifications; 4) consistent with Taguchi’s concept of tolerance design since it promotes central tendencies with small deviations in product properties, rather than a goal post mentality (Devore 1995); and, 5) consistent with many design axioms to minimize information content since the production yield will tend to decline geometrically as the number of requirements rise (Suh 1990).ExtensibilityWhile robustness is a critical measure of system behavior, other measures are useful in system design. Extensibility is defined as the capability of a quality attribute to be extended to the broadest achievable range relative to uncontrolled variation. The lower extensible limit, LEL , and upper extensible limit, UEL , for each quality attribute may be derived directly from the function matrix and control limits on the decision variables, or from a series of optimizations for more general systems:UCLX LCL y UEL y LEL i X i i Xi ≤≤==max min (6)It should be noted that in achieving the minimum or maximum quality attribute, the decision variables may be selected such that some or all of the other quality attributes are not within specification. The invalidation of other quality specifications is not a limitation of the extensibility measure, since the extensibility is intended to simply measure the total extent to which each quality attribute can be modified.Once the LEL and UEL are available, the extensibility of each quality attribute, E i , can be evaluated according to the established method for the process capability indices of eq. (1) and (2), e.g.σ6i i i LEL UEL E −= (7) ⎟⎠⎞⎜⎝⎛−−=σµσµ3,3min i i i i i LEL UEL E (8) The system extensibility, E , may be calculated as an inverse joint probability as previously described in eq. 5, and discussed for system robustness. For the asymmetric index of eq. 8, the extensibility is dependent upon the selection of the decision variables in a system design, and the resulting mean of each quality attribute.The extensibility measure seems trivial, yet provides valuable information that should be considered during system design prior to robustness issues. Generally, system designs should exhibit an extensibility index significantly greater than the robustness index. If the extensibility is less than one, then the system is largely incapable of being designed, i.e. the entire range of quality attributes is small compared to the variation that the quality attributes exhibit. If the system extensibility is small, then several alternatives are suggested. First, the extensibility measures of each quality attribute should be inspected to identify and eliminate those quality attributes that are not extensible. If inextensible quality attributes cannot be eliminated through negotiation, then development of a different system design concept may provide increased extensibility. One common approach is to augment the decision variables with added degrees of freedom that will significantly affect the behavior of the quality attributes.ControllabilityWhile the extensibility index provides a measure of the total range of the quality attributes, significant portions of the range will require other quality attributes to fall outside of theirspecification. As such, the controllability is defined as the capability of a quality attribute to be extended to the broadest range relative to uncontrolled variation while maintaining all quality attributes within specification. Thus, each quality attribute can only be extended to the point at which other quality attributes become unacceptable. In a broad sense, the controllable space may be considered as the feasible performance space (of an engineering design) or process window (of a manufacturing process). The feasible region is a polytope formed by the joint intersection of the half-spaces corresponding to the constraint surfaces of all the system specifications. While the feasible region can be solved efficiently for moderately sized linear systems via the extensive Simplex Method (Zhu, Zhao et al. 2000), it is generally believed that the solution of the feasible region is infeasible for large linear systems or even small nonlinear systems.For practical characterization of system behavior, however, the lower global controllable limit, LGL , and upper global controllable limit, UGL , for each quality attribute may generally be resolved from a series of optimizations:j USL y LSL UCL X LCL y UGL y LGL jj j i X i i X i ∀≤≤≤≤==max min (9)Once the LGL and UGL are available, the controllability of each quality attribute, C i , can be evaluated according to the established method for the previously defined indices in eq. (1-2) and (7-8). The system controllability, C , may be calculated as an inverse joint probability as previously described in eq. 5, and discussed for system robustness. Again, the asymmetric controllability is dependent upon the selection of the decision variables in a system design, and the resulting mean of each quality attribute.It should be noted that in resolving the global controllable limits for each quality attribute, the decision variables will be selected such that all quality attributes are within specification. Since theLGL and UGL are constrained to the LSL and USL, the controllability index will be less than the robustness index. Thus, it is necessary for a system to be robust to be controllable.However, the controllability index does provide different information than the robustness or extensibility indices. The LGL and UGL are the broadest limits that can be achieved while ensuring other quality attributes (and the overall system) are within specification. Thus the controllability provides a measure indicative of the extent of the system to be significantly modified within specification. It is possible for a system to be extensible and robust, but not controllable. In such a system, multiple quality attributes will conflict and exhibit negative correlations, i.e. desirable changes in a quality attribute will bring about undesirable changes in other quality attributes. If the controllability index is less than one, it is indicative that the system design may not be able to be successfully modified if significant changes in the mean quality attributes is necessary. As such, a different system design concept with fewer quality attributes, augmented degrees of freedom, or differing system behavior may be necessary.It should also be noted that the controllability index, unlike the previous two indices, will also reflect the infeasibility of a system design. If the quality attributes conflict significantly and the specification levels are unrealistic, then no selection of the decision variables may result in a set of quality attributes that meet specification. As such, no solution will be obtained for the LGL and UGL, and the controllability index will be undefined.FlexibilityThe controllability index provides a measure of the adaptability of the system while maintaining all quality attributes within specification. However, it is sometimes desired to modify the level of individual quality attributes while maintaining other quality attributes fixed. As such, the flexibility is defined as the capability of a quality attribute to be extended to the broadest feasible range relative to uncontrolled variation while maintaining the level of other quality attributes. In a general sense,the flexibility of a quality attribute can be derived by successively intersecting the global feasible space with additional equality constraints. This approach is generally infeasible. For practical characterization of system behavior, the lower flexible limit, LFL , and upper flexible limit, UFL , for each quality attribute may generally be resolved from a series of optimizations:i j y UCL X LCL y UGL y LGL j j i Xi i Xi ≠∀=≤≤==τmax min (10) Once the LFL and UFL are available, the flexibility of each quality attribute, F i , can be evaluated according to the established method for the previously defined indices in eq. (1-2) and (7-8). The system flexibility, F , may be calculated as an inverse joint probability as previously described in eq. 5, and discussed for system robustness.It should be noted that in resolving the flexible limits for each quality attribute, the decision variables will be selected such that all other quality attributes are maintained near their current levels. Since the LFL and UFL are constrained to the LGL and UGL , the flexibility index will be less than the controllability index. Thus, it is necessary for a system to be controllable to be flexible. If a system is infeasible, it will not possess any feasible space and thus both the controllability and flexibility indices will be undefined.There are some substantive differences in the definition and behavior of the controllability and flexibility indices. The controllability index is derived from the global feasible space that maintains all quality attributes within specification. While the asymmetric controllability index is dependent on the selection of the decision variables, the symmetric and more general controllability index (e.g. eq. 8) is not. As such, the controllability of the system can be estimated without selecting a specific design. However, the flexibility of the system is dependent upon the desired targets for the quality attributes. As previously described, the range of flexibility is derived from the global space with additionalconstraints based on maintaining the value of the other quality attributes. Since the polytope is irregularly shaped and certainly not prismatic, the selection of the targets for the quality attributes will result in significant changes in the system flexibility. In other words, the targets for the quality attributes will determine the nearest active constraint as well as the amount of allowable slack for the decision variables. If a target value is selected near the edge of the controllable region, then the system flexibility will quickly degrade.ApplicationConcepts of extensibility, robustness, controllability, and flexibility will now be applied to the manufacture of a digital videodisc (DVD). The diversity of quality requirements of the DVD, coupled with numerous formats and manufacturing systems, has made the optical media industry open to process improvement opportunities. In addition, growth in the DVD market has left production facilities searching for cost effective added capacity. All DVD formats require bonding of two 0.60 mm polycarbonate substrates. Injection molding is the primary manufacturing process in optical media creation. Each disc is composed of an optically transparent substrate (typically polycarbonate), with one or more substrates containing a reflective metalized data surface. For prerecorded media, the data is stored on a disc in the form of pits that are molded into the disc during the injection molding process. The data is part of the disc; the data is not written in a secondary operation as in magnetic media. The bonding process combined with the small definition of data pits requires stringent flatness specifications of each DVD substrate. In addition, substrate thickness and birefringence play significant roles in the ability of the DVD laser to properly read the optical media (Oshiro, Goto et al. 1997; Park, Han et al. 1998; Shin, Rhee et al. 1998).Previous research has focused on methodologies for process characterization through empirical models (Hatch 2000). The results of a main effect DOE identified the critical processing parameters that justified further exploration. The newly recognized parameters were segregated into stagesbased on idealized interactions affects. Using a designed experiment that yields nonlinear models, including interaction effects, the system can be then optimized within each stage. DVD experiments were conducted on a Sumitomo SD30 injection-molding machine. All laboratory experimentation was conducted at General Electric Plastics Polymer Processing Development Center, in the Optical Media Development Center (OMDC). In the OMDC, the Sumitomo SD30 is configured as a batch process. The OMDC possesses the analytical testing equipment required to characterize all relevant quality characteristics, including a TopoMetrix Atomic Force Microscope, Dr. Schenk Optical Disk Scanner, and multiple CD Associates Stamper Player Signal Analysis instruments. Multiple replicates were measured for each run of the DOE. Data from designed experiments and/or random data can be used to develop a model of the system.Solution of the model requires determining the model coefficients, or estimation of parameters, and testing for significance (Myers, Khuri et al. 1989). The parameters βj are the regression coefficients and represent the expected change in response, y , due to the change in x j . To estimate the regression coefficients suppose there are n > p observations on the response variable , y 1, y 2,…, y n . For each response variable y k there is a set of predictors, x ij , where k denotes the k th observation of the x j predictor variable. A general response surface model representing the system can be expressed by a multiple linear regression model:(11),110k p j kj j k x y εββ++=∑−=where the error of the model, ε, is assumed normal and has an expected value, E(ε) = 0, variance, Var(ε) = σ2, and the errors, εi , are uncorrelated random variables (Neter, Kutner et al. 1996). Both the mean and variance are modeled as a function of the processing parameters. Frequently the goodness of fit, or how well the model fits the data is expressed in terms of R 2 or R 2-adjusted:yyEyy R S SSS SS R −==12 (12)()22111)1()(1Rp n n n Syyp n SS R Eadj−⎟⎟⎠⎞⎜⎜⎝⎛−−−=−−−= (13)where S yy = SS R + SS E , and SS R is the sum square due to regression model and SS E is the sum square due to the error.In this work, the DVD processing space was characterized using two different system models. The first model consists of nine input processing parameters and eight output quality characteristics. The nine input processing parameters are based on the injection molding machine control inputs. The melt temperature and the clamping profile are quantified through these parameters, x i for j = 1, 2, 3..9:(14)⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢⎣⎡=⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢⎣⎡Time Change Point Transfer V/P 2 Time Clamp 2 Tonnage Clamp 1 Time Clamp 1 Tonnage Clamp Time Cooling Temp Mold Temp Melt 987654321x x x x x x x x x The eight output quality parameters evaluate the flatness and optical quality characteristics for the DVD substrate. The tangential, radial, dishing, and outer diameter (OD) deviation measurements guarantee flatness of the disc. Flatness is critical to ensuring proper bonding for the DVD substrates. Optical specifications are characterized by birefringence measurements. The output parameters and quality specifications are:Using linear regression techniques, a linear empirical model of the system was generated utilizing quality data from 575 molded DVDs across 115 process settings.

The {minimum, median, and maximum} R 2-adjusted value across all eight quality attributes for the full quadratic model was {59.2%, 76.7%, 91.3%}, significantly higher than those of the linear models {26.8%, 57.5%, 82.6%}. It should be noted that the complexity of the process, process variance, and lack of knowledge about the true process behavior prevents the development of perfect process models. However, the linear models are of significant value in understanding the trends and constraints of the DVD manufacturing process.RobustnessThe robustness of the system is evaluated according to eq. (1) and 2, which compares the relative width of the specifications to the observed variance for each quality attribute. The specifications and measured variance for the manufacturing of DVD substrates is shown in Table 1. The robustness, R i , of each quality attribute is very high when measured with the symmetric process capability index (eq. 1). Since there are fifteen standard deviations between the specifications, the aggregate system robustness across all quality attributes is approximately equal to the least robust quality attribute.Table 1: System Robustness of a DVD Substrate Manufacturing ProcessAs previously mentioned, however, symmetric measures of robustness disregard the error between the mean and target performance value. As such, the robustness of the system, as measured with an asymmetric definition, is dependent upon the selection of the decision variables. One natural tendency would be to evaluate the system at the central value of the decision variables. Such an approach may be valid since the control limits on the decision variables are usually intentionally set to encompass the useful region of the decisions. Inspection of the asymmetric robustness at the center point of the system design immediately indicates that the system design is infeasible since the maximum birefringence and the tangential deviations are outside the specified limits. Clearly the selected values of the decision variables are poor, and hopefully may be improved.One approach is to select the decision variables to provide a more robust design. In this case, an optimization approach is frequently utilized to bring all quality attributes far within their specifications. The right most column of Table 1 provides the resulting robustness of this system at the optimal settings of the decision variables. It is evidenced that the several of the quality attributes have a robustness less than two, and the aggregate robustness is 1.36 indicating that approximately four standard deviations (3σ*1.36 ≈ 4σ) lie between the mean performance and the specifications. This level of robustness would likely be acceptable in many manufacturing plants. Further inspection of the optimal decision settings indicates that many decision variables are constrained by their control limits, and that a more optimal solution could be obtained by modifying the control limits, if possible.。
