Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer’s crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.

From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn’t tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

When Should a Leader Apologize and When Not?

Why Difficult?

When we wrong someone we know,even not intentionally,we are generally expected to apologize so as to improve the situation. But when we’re acting as leaders,the circumstances are different. The act of apology is carried out not only at the level of the individual but also at the level of the institution. It is a performance in which every expression matters and every word becomes part of the public record. Refusing to apologize can be smart,or it can be stupid. So,readiness to apologize can be seen as a sign of strong character or as a sign of weakness. A successful apology can turn hate into personal and organizational harmony—while an apology that is too little,too late,or too obviously strategic can bring on individual and institutional ruin. What,then,is to be done?How can leaders decide if and when to apologize publicly?

Why Now?

The question of whether leaders should apologize publicly has never been more urgent. During the last decade or so,the United States in particular has developed an apology culture—apologies of all kinds and for all sorts of wrongdoings are made far more frequently than before. More newspaper writers have written about the growing importance of public apologies. More articles,cartoons,advice columns,and radio and television programs have similarly dealt with the subject of private apologies.

Why Bother?

Why do we apologize?Why do we ever put ourselves in situations likely to be difficult,embarrassing,and even risky?Leaders who apologize publicly could be an easy target. They are expected to appear strong and capable. And whenever they make public statements of any kind,their individual and institutional reputations are in danger. Clearly,then,leaders should not apologize often or lightly. For a leader to express apology,there needs to be a good,strong reason. Leaders will publicly apologize if and when they think the costs of doing so are lower than the costs of not doing so.

Why Refuse?

Why is it that leaders so often refuse to apologize,even when a public apology seems to be in order?Their reasons can be individual or institutional. Because leaders are public figures,their apologies are likely to be personally uncomfortable and even professionally risky. Leaders may also be afraid that the admission of a mistake will damage or destroy the organization for which they are responsible. There can be good reasons for hanging tough in tough situations,as we shall see,but it is a high-risk strategy.

―→·Public apology is much more than a(an) 1.act.

·It’s no 2. job to strike a balance between apologizing or not.

·There needs to be a sufficient reason for a leader to 8. in public.―→ ·Making apologies is likely to be personally uncomfortable and 9..

·Admission of a mistake or wrongdoing will probably do 10.to their organization.
