Although "naming rights" have proliferated in American higher education for the past several decades, the phenomenon has recently expanded to extraordinary lengths. Anything to get an extra dollar out of donors is fair game. I know colleges and universities sorely need to raise funds in these times of fiscal constraints, but things have gotten a bit out of hand.

Universities and colleges have long been named after donors—think of Harvard, Yale, Brown, and many others. John Harvard would hardly get a bench named after him today, given the modesty of his gift of books for the library back in the seventeenth century. Now it takes much more to get one’s name on a college. One institution, Rowan University of New Jersey, changed its name (from Glassboro State College) not long ago when a large donation was made. Buildings, too, have been affected. Traditionally, they were named after people such as distinguished scholars or visionary academic leaders; now they’re often named after big donors.

Why is all of this happening now The main motivation for the naming frenzy is, of course, to raise money. Donors love to see their names, or the names of their parents or other relatives, on buildings, schools, institutions, professorships, and the like. Increasingly, corporations and other businesses also seek to benefit from having their names on educational facilities. Today, no limits seem to exist on what can be named. If something does not have a name, it is up for grabs—a staircase, a pond, or a parking garage. Once all the major facilities have titles, lesser things go on the naming auction block. Colleges and universities, public and private, are all under increased pressure to raise money, and naming brings in cash.

It is unproductive. Separate branding weakens the focus and mission of an institution and perhaps even its broader reputation. It confuses the public, including potential students, and feeds the idea that the twenty-first-century university is simply a confederation of independent entrepreneurial domains.

The trends we see now in the United States, and perhaps tomorrow in other countries, will inevitably weaken the concept of the university as an institution that is devoted to the search for truth and the transmission of knowledge. All this naming distracts from the mission of an institution that has almost a millennium of history and cheapens its image. It is a sad symbol indeed of the commercialization and entrepreneurialism of the contemporary university.

In the 4th paragraph, the word "unproductive" probably means ().

A. naming cannot bring benefits to the donating businesses

B. separate naming yields a broader reputation for a university

C. out-of-hand naming weakens the goal of higher education

D. naming cannot raise enough money for a university’s development

希赛公司最近签订了一份控制系统软件的研制合同。合同技术要求如下：
①本控制系统的软件运行平台拟采用嵌入式实时操作系统，控制系统的工作周期为10ms，要求控制软件能够精确地按事先预定的时间顺序完成数据的采集、处理和输出。
②为了提高整个系统的可靠性，控制系统采用容错处理，即用两个相对独立的计算机承担相同的工作，通过交叉对比，实现控制的双余度管理；当任何一台计算机出现故障时，系统可以进行单余度控制。系统结构如图12-21所示。

③在10ms工作周期内的时间分配如表12—15所示。

表12—15 10ms工作周期内的时间分配
功 能	时间要求(mS)
余度数据采集	1.5
输入交叉对比	1
数据处理	4
比较监控	1
输出交叉对比	1.5
其他	1

公司总工程师将本项任务交付给项目主管李工程师实施，要求李工按双方合同要求完成本项目的策划、需求分析和方案设计工作，重点强调系统的可靠性要求，并特别提示：目前比较流行的嵌入式操作系统普遍采用可抢占式优先级调度策略，不能满足用户关于“能够精确地按事先预定的时间顺序完成数据的采集、处理和输出”的要求。

请用200字以内的文字说明李工应如何设计优先级调度策略，并按照如表12-14所示的要求实现任务流程处理。
