(三)背景资料某施工单位承担了我国东南某地直埋光缆线路工程,采用包工不包料的方式承包。项目负责人在开工前组织全体施工人员开会,由现场勘察人员作安全技术交底,并指定由质量负责人兼任安全员,会议没有做书面记录,会后按照分工分别投入工程施工。在材料进场检验时,检验人员仔细对各种材料外观、材料出厂合格证进行了检查,并对光缆长度以及光电特性进行了抽测,各种检验均有记录。在施工过程中发生了以下事件:事件一:在开挖光缆沟工作进行中,项目部从天气预报中得知强台风即将来临,于是在没有通知监理工程师的情况下,决定赶在台风来临前把光缆布放在还在开挖的光缆沟中,并立即回填,以免光缆沟被冲毁。事后,监理工程师拒绝为沟深和放缆等隐蔽工程签字。事件二:施工单位在中继段测试时,发现有一芯光纤衰耗过大,经现场分析确认是由于光缆本身质量不合格造成的。问题

     Andy Steele lives just a few blocks from the campus of Black Hills State University in Spearfish,

S.D., so commuting(经常往返) to class isn't the problem. But he doesn't like lectures much, isn't a

morning person, and wants time during the day to restore motorcycles.

     So Steele, a full-time senior business major, has been taking as many classes as he can from the

South Dakota State system's online offerings. He gets better grades and learns more, he says, and

insists he isn't missing out on the college experience.

     "I still know a lot of people from my first two years living on campus, and I still meet a lot of people,"

he says. But now, he sets his own schedule.

    At least 2.3 million people took some kind of online courses, according to a recent survey by The

Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses

also offer online ones. But what were once two different types of classes are looking more and more

alike and often falling into the same pool of students.

    At some schools, online courses originally intended for non-traditional students living far from campus

have proved surprisingly popular with on-campus students. A recent study found 42 percent of the

students enrolled(登记) in its distance education courses were located on campus at the university that

was hosting the online courses.

     Numbers vary depending on the policies of particular colleges, but other schools also have students

mixing and matching online and "face-to-face" credits. Motives range from lifestyle to adapting a job

schedule to getting into high-demand courses.

    Washington State had about 325 on-campus undergraduates taking one or more distance courses last

year. As many as 9,000 students took both distance and in-person classes at Arizona State last year.

"Business is really about providing choices to their customers, and that's really what we want to do," said

Sheila Aaker, extended services coordinator (协调人) at Black Hills State.

     Many schools, such as Washington State and Arizona State, let departments and academic units

decide who can take an online course. They say students with legitimate academic needs-a conflict

with another class, a course they need to graduate that is full---often get permission, though they still must

take some key classes in person.
