demonstration of the group’s power rather than an individual criminal act.2.Psychiatrist Ansar Haroun,who served in the U.S.Army Reserves in the first Gulf War and more recently in Afghanistan,says that terrorist groups often resort to psychological warfare because it’s the only tactic they have available to them.3.In a year marked by uncertainty and upheaval,officials at New Orleans universities that draw applicants nationwide are not following the usual rules of thumb when it comes to college admissions.4.Loyola University,whose trustees will vote May19on whether to drop several degree programs and eliminate17faculty positions,received fewer applications--about2,900to date,compared with3,500in recent years.5.Historically black Dillard University,which is operating out of a hotel and was forced to cancel its annual March open house,also saw drops,as did Xavier University,a historically black Catholic institution that fell behind its recruitment schedule.6.The difference between avian flu and human flu that should be commanding our rapt attention today is that avian influenza,specifically the H5N1strain known as bird flu,threatens to become the young people’s plague.7.The victims overreact to the alien virus,triggering a massive immune response called a cytokine storm,turning healthy lungs into a sodden mass of dying tissues congested with blood,toxic fluid,and rampaging inflammatory cells.8.Seem like hype?Not to the medical experts who discussed these scenarios during last week’s U:S.News Health Summit on preparedness.9.Today’s college students are more narcissistic and self-centered than their predecessors,according to a comprehensive new study by five psychologists who worry that the trend could be harmful to personal relationships and American society.10.The Employee Free Choice Act would allow a union to be recognized after collecting a majority of vote cards,instead of waiting for the National Labor Relations Board to oversee a secret ballot election,which can occur more than50days after the card vote is completed.11.Employment became widespread when the enclosures of the17th and18th centuries made many people dependent on paid work by depriving them of the use of the land,and thus of the means to provide a living for themselves.ter,as transport improved,first by rail and then by road,people traveled longer distances to their places of employment until,eventually,many people’s work lost all connection with their home lives and the places in which they lived.13.The time has certainly come to switch some effort and resources away from the impractical goal of creating jobs for all,to the urgent practical task of helping many people to manage without full-time jobs.14.Various innovations have been introduced as ways to break off our system which forces students through a series of identical classrooms in which teachers do most of the talking and students have little opportunity to respond.15.Among these innovations are team teaching and teacher aides,non-graded elementary and secondary schools,independent study,curricula focused on helping students discover things for themselves rather than on trying to tell them everything,and schools designed for maximum flexibility so that students can work alone,or in small groups,or take part in large group instruction via diverse media.16.Many people who have a strong dislike to organizing instruction scientifically and to bringing new technology into the schools and colleges fail to realize that the present system is in many respects mechanical and rigid.17.There is no escaping the evidence that many students themselves feel little enthusiasm and even outright hostility for the present way schools and colleges are organized and instruction is handled.18.To be useful as clocks,the elements have to be fairly common in natural minerals, unstable but decay slowly over millions of years to form recognizable“daughter”products which are preserved minerals.19.For example,an atom of radioactive rubidium decays to form an atom of strontium(another element)by converting a neutron in its nucleus to a proton and releasing an electron,generating energy in the process.20.The main problems with this dating method are the difficulty in finding minerals containing rubidium,the accuracy with which the proportions of rubidium and strontium are measured,and the fact that the method gives only the date when the mineral last cooled below the blocking temperature.21.Its care and management have differed over time,of course,but so,too,have its identity,visibility,and meaning.22.At one time,it was thought that cancer was a“disease of civilization,”belonging to much the same causal domain as“neurasthenia”and diabetes,the former a nervous weakness believed to be brought about by the stress of modern life and the latter a condition produced by bad diet and indolence.23.What made the argument striking in this instance was that it was being offered by none other than the former five-term Federal Reserve Chairman Alan Greenspan: iconic libertarian,preeminent defender of the free market,and(at least until recently) the nation’s foremost devotee of Ayn Rand.24.And this,in turn,has led to wider–and not unreasonable–fears that we are living in not merely a plutonomy,but a plutocracy,in which the rich display outsize political influence,narrowly self-interested motives,and a casual indifference to anyone outside their own rarefied economic bubble.25.It was understanding the idea’s significance and selling it to the public that made Darwin great,according to the Arnold Arboretum’s new director.26.Friedman said that Darwin’s thinking on natural selection as the mechanism of evolution was shared by few,most prominently Alfred Wallace,whose writing on the subject after years in the field spurred Darwin’s writing of“On the Origin of Species.”27.Most people experience this eerie phenomena at least once in their lives,but those who are sleep deprived are more likely to have panicked episodes of paralysis that are usually accompanied by hallucinations,as well.28.Research has revealed that REM sleep,or dream-sleep,helps solidify the“fragile”memories the brain creates throughout the day so that they can be easily organized and stored in the mind’s long–term cache.29.Vittorio Colao,the boss of Vodafone,which operates or partially owns networks in31countries,argues that the farther south you go,the more people use their phones, even past the equator:where life is less organized,people need a tool,for example to rejig appointments.30.For instance,in countries where many people have holiday homes they are more likely to give out a mobile number,which then becomes the default where they can be reached,thus undermining the use of fixed-line phones.31.An11th-century metalworking site recently discovered in the city of York is likely evidence of a makeshift recycling center;where Vikings took weapons for reprocessing after battle,according to historian Charles Jones,organizer of the Fulford Battlefield Society,which advocates preserving the battle site against potential development.。
