Crossing Wesleyan University’s campus usually requires walking over colorful messages chalked on the ground. They can be as innocent as meeting announcements, but in a growing number of cases the language is meant to shock. It’s not uncommon, for instance, to see lewd reference to professors’ sexual preferences scrawled across a path or the mention of the word "Nig" that African-American students say make them feel uncomfortable. In resp0nse, officials and students at schools are now debating ways to lead their communities away from forms of expression that offend or harass. In the process, they’re putting up against the difficulties of regulating speech at institutions that pride themselves on fostering open debate. Mr. Bennet of Wesleyan says he had gotten used to seeing occasional chalkings filled with four-letter words. Campus tradition made any horizontal surface not attached to a building a potential billboard. But when chalkings began taking on a more threatening and obscene tone, Bennet deeided to act. "This is not acceptable in a workplace and not acceptable in an institution of higher learning," Bennet says. For now, Bennet is seeking input about what kind of message-posting policy the school should adopt. The student assembly recently passed a resolution saying the "right to speech comes with implicit responsibilities to respect community standards". Other public universities have confronted problems this year while considering various ways of regulating where students can express themselves. At Harvard Law School, the recent controversy was more linked to the academic setting. Minority students there are seeking to curb what they consider harassing speech in the wake of a series of incidents last spring. At a meeting held by the "Committee on Health Diversity" last week, the school’s Black Law Students Association endorsed a policy targeting discriminatory harassment. It would trigger a review by school officials if there were charges of "severe or pervasive conduct" by students or faculty. The policy would cover harassment based on, but not limited to, factors such as race, religion, creed, sexual orientation, national origin, and ethnicity. Boston attorney Harvey Silverglate, says other schools have adopted similar harassment policies that are actually speech codes, punishing students for raising certain ideas. "Restricting students from saying anything that would be perceived ns very unpleasant by another student continues uninterrupted," says Silverglate, who attended the Harvard Law Town Meeting last week. What is the typical scene found in the campus of Wesleyan University
Think of the ocean on a calm day. Ignoring the rise and fall of the waves, you might imagine the surface was dead flat the whole way across. You’d be wrong. Hills and valleys are as much as a feature of the sea as the land, although on a much smaller scale. These undulations have a variety of causes. Tides, currents, eddies, winds, river flow and changes in salinity and temperature push the sea level up in some places and down in others by as much as 2 meters. Ever tried swimming uphill How do we map these oceanic hills and valleys First, we need to know what the planet would look like without them. This is where the geoid (大地水准面) comes in. It is a surface where the Earth’s gravitational potential is equal and which best fits the global mean sea level. It is approximately an ellipsoid, though uneven distribution of mass within the Earth means that it can vary from this ideal by up to 150 meters. The geoid represents the shape the sea surface would be if the oceans were net moving and affected only by gravity. Thus it can be used as a reference to measure any deviations in the ocean surface height that aren’t caused by gravity—the hills and valleys, for instance, or any regional increase in sea level. So how do you measure the geoid and the ocean’s irregular topography It’s complicated. Geophysicists calculate the geoid using data on variation in gravitational acceleration from several dozen satellites. The hills and valleys of the oceans are all very interesting, but can the geoid tell us anything more significant about the state of the planet It certainly can. Knowing accurately where the geoid lies and how the Ocean surface deviates from it will help meteorologists spot changes in Ocean currents associated with climate change. The circumpolar current around Antarctic is one they are particularly interested in. It can also predict local climate variations produced by events such as El Nino, El Nino keeps warm water that would normally move westwards close to the coast of South America, deprives Southeast Asia of its monsoon rains, and increases rainfall on the west coast of the Ametlca. Since temperature changes cause changes in sea level, geoid-watchers should be able to prepare us before it strikes. According to the passage, geoid may be helpful in all the following areas EXCEFT______.
