81.The overall result has been to make entrance to professional geological journals harder for a mateurs,a result that has been reinforced by the widespread introduction of refereeing,first by national journals in the 19th century and then by several local geological journals in the 20th century.
82.A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies,whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way.
83.Sad to say,this project has turned out to be mostly low——level findings about factual errors and spelling and grammar mistakes,combined with lots of head——scratching puzzlement about what in the world those readers really want.
84.I believe that the most important forces behind the massive M&M wave are the same that underlie the globalization process： falling transportation and communication costs,lower trade and investment barriers and enlarged markets that require enlarged operations capable of meeting customers''demands.
85.A lateral move that hurt my pride and blocked my professional progress promoted me to abandon my relatively high profile career although,in the manner of a disgraced government minister,I covered my exit by claiming I wanted to spend more time with my family.
86.I have discovered,as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build-up of stress,that abandoning the doctrine of juggling your life,and making the alternative move into downshifting brings with it far greater rewards than financial success and social status.
87.While in America the trend started as a reaction to the economic decline-after the mass redundancies caused by downsizing in the late ''80s-and is still linked to the politics of thrift,in Britain,at least among the middle-class down shifters of my acquaintance,we have different reasons for seeking to simplify our lives.
88.For the women of my generation who were urged to keep juggling through the''80s,down-shifting in the mid''90s is not so much a search for the mythical good lift-growing your own organic vegetables,and risking turning into one-as a personal recognition of your limitations.
89.If you are part of the group which you are addressing,you will be in a position to know the experiences and problems which are common to all of you and it''11 be appropriate for you to make a passing remark about the inedible canteen food or the chairman''s notorious bad taste in ties.
90.There are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy far greater precision than highly skilled physicians can achieve with their handsaone
91.But if robots are to reach the next stage of laborsaving utility,they will have to operate with less human supervision and be able to make at least''a few decisions for themselves-goals that pose a real challenge.
92.But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant,instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd.
93.The OECD estimates in its latest Economic Outlook that,if oil prices averaged $22 a barrel for a full year,compared with $13 in 1998,this would increase the oil import bill in rich economies by only 0.25——0.5% of GDP.
94.One more reason not to lose sleep over the rise in oil prices is that,unlike the rises in the 1970s,it has not occurred against the background of general commodity-price inflation and global excess demand.
95.Although it ruled that there is no constitutional right to physician-assisted suicide,the Court in effect supported the medical principle of double effect,a centuries-old moral principle holding that an action having two effects——a good one that is intended and a harmful one that is foreseen——is permissible if the actor intends only the good effect.
96.Nancy Dubler,director of Montefiore Medical Center,contends that the principle will shield doctors who until now have very,very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death.
97.On another level,many in the medical community acknowledge that the assisted—suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying.
98.It identifies the undertreatment of pain and the aggressive use of ineffectual and forced medical procedures that may prolong and even dishonor the period of dying as the twin problems of end——of——life care.
99.In other words,there is a conventional story line in the newsroom culture that provides a backbone and a ready-made narrative structure for otherwise confusing new.
100.If it did,it would open up its diversity program,now focused narrowly on race and gender,and look for reporters who differ broadly by outlook,values,education,and class.
