“I had a Welsh speaking test. I'd had to memorize a paragraph in front of the whole class. I just couldn’t do it,” says 13-year-old Mary. “I pretended to be ill.” But Mary did not enjoy her day off. “I watched TV all day — it was boring. I wished I had gone to school.”

Mary’s story is not unusual in Britain. According to the latest government figures, pupil absences are rising, despite schools taking a hard line on truancy (逃学).

Philippa James, a PhD researcher at Cardiff University’s school of social sciences, thinks she knows why: “The more schools improve methods of detection(检查), the more children work out better methods of deception.” Teenagers told her it was now harder to skip a single lesson, so they’d miss whole days to avoid being caught.

For several years, James has researched student truancy of 60 teenagers, aged 13 and 14, including Mary, to see how the teenagers truant, for how long, and why.

Through online conversations and face-to-face interviews, she discovered that most truancy was “a response to factors within the school”. Truants are not necessarily less advanced or less intelligent. They complained of teachers who failed to engage them, and of “boring” lessons. “Many truants really enjoy school and believe in education, but drop out when aspects of it were ineffective.” James says.

The views of students like Adam, who believes that skipping lessons has little impact on his schooling, were common. “I only take-off for a lesson, or a couple of days. It doesn’t affect my education,” he told James.

James’ study concludes that schools need to address the question of why pupils want to leave in the first place. “Pupils need help from the start.” she says. “It’s a two-way process – schools must be responsive. We need to look at the reasons for truancy rather than the number, so that instead of walking away from school, students have the skills and chances to talk through problems and make a change.”

综合题:ABC公司正在考虑改变它的资本结构,有关资料如下:(1)公司目前债务的账面价值1000万元,利息率为5%,债务的市场价值与账面价值相同;普通股4000万股,每股价格1元,所有者权益账面金额4000万元(与市价相同);每年的息前税前利润为500万元。该公司的所得税税率为15%。(2)公司将保持现有的资产规模和资产息前税前利润率,每年将全部税后净利润分派给股东,因此预计未来增长率为零。(3)为了提高企业价值,该公司拟改变资本结构,举借新的债务,替换旧的债务并回购部分普通股。可供选择的资本结构调整方案有两个:①举借新债务的总额为2000万元,预计利息率为6%;②举借新债务的总额为3000万元,预计利息率为7%。(4)假设当前资本市场上无风险利率为4%,市场风险溢价为5%。要求:(1)计算该公司目前的权益成本和贝塔系数(计算结果均保留小数点后4位)。(2)计算该公司无负债的贝塔系数和无负债的权益成本(提示:根据账面价值的权重调整贝塔系数,下同)。(3)计算两种资本结构调整方案的权益贝塔系数、权益成本和实体价值(实体价值计算结果保留整数,以万元为单位)。(4)判断企业应否调整资本结构并说明依据,如果需要调整应选择哪一个方案?
