When Liam McGee departed as president of Bank of America in August, his explanation was surprisingly straight up. Rather than cloaking his exit in the usual vague excuse, he came right out and said he was leaving “to pursue my goal of running a company.” Broadcasting his ambition was “very much my decision,” McGee says. Within two weeks, he was talking for the first time with the board of Hartford Financial Services Group, which named him CEO and chairman on September 29.

McGee says leaving without a position lined up gave him time to reflect on what kinds of company he wanted to run. It also sent a clear message to the outside world about his aspirations. And McGee isn’t alone. In recent weeks the No. 2 executives at Avon and American Express quit with the explanation that they were looking for a CEO post. As boards scrutinize succession plans in response to shareholder pressure, executives who don’t get the nod also may wish to move on. A turbulent business environment also has senior managers cautious of letting vague pronouncements cloud their reputations.

As the first signs of recovery begin to take hold, deputy chiefs may be more willing to make the jump without a net. In the third quarter, CEO turnover was down 23% from a year ago as nervous boards stuck with the leaders they had, according to Liberum Research. As the economy picks up, opportunities will abound for aspiring leaders.

The decision to quit a senior position to look for a better one is unconventional. For years executives and headhunters have adhered to the rule that the most attractive CEO candidates are the ones who must be poached. Says Korn Ferry, senior partner Dennis Carey: “I can’t think of a single search I’ve done where a board has not instructed me to look at sitting CEOs first.”

Those who jumped without a job haven’t always landed in top positions quickly. Ellen Marram quit as chief of Tropicana when the business became part of PepsiCo (PEP) a decade ago, saying she wanted to be a CEO. It was a year before she became head of a tiny internet-based commodities exchange. Robert Willemstad left Citigroup in 2005 with ambitions to be a CEO. He finally took that post at a major financial institution three years later.

Many recruiters say the old disgrace is fading for top performers. The financial crisis has made it more acceptable to be between jobs or to leave a bad one. “The traditional rule was it’s safer to stay where you are, but that’s been fundamentally inverted,” says one headhunter. “The people who’ve been hurt the worst are those who’ve stayed too long.”

The number of accidents involving pedestrians (行人) wearing headphones is on the rise, a report suggests, causing fresh warning from road safety groups in Britain.

A US-based study found a total of 116 reports of death or injury to pedestrians wearing headphones between 2004 and 2011, jumping from 16 in 2005 to 47 in 2011.

Most victims were men (68%) and under the age of 30 (67%), with around one in ten of all cases (9%) under the age of 18.Some 89% of the cases occurred in urban areas and more than half (55%) of the victims were struck by trains .

Eighty-one of the 116 accidents (70%) resulted in the person’s death—even though a warning was sounded in around a third of the cases.

The study concluded, “The use of headphone may be a safety risk to pedestrians , especially in environments with moving vehicles（cars）. Further research is needed to determine if and how headphone use threatens pedestrian safety.” British road safety groups warned pedestrians to be careful.

Floor Lieshout, director of Youth For Road Safety, said, “ This study shows once more the importance of using all of our senses while we are near traffic. It is important that we find an attractive way to make youth learn about the risks of wearing headphones in traffic.”

Andrew Howard , who is the head of road safety at the Automobile Association, added that some pedestrians can be “so focused in their own little world they forget the world going on around them”. That can include headphone wearers, Howard said, but also people talking on phones.

However, Howard said that more researches needed to be done.

Earlier studies have shown that people wearing headphones or talking on phones can suffer “inattentional blindness” which makes them isolated (孤立) from the world around them .

Ian Harvey, at the charity Civic Voice, said that “ to defeat isolation and to help build a civic(文明的) society, people need to interact(交往) with each other .

He said, “ A basis for any civilized society is communication—Surfing the web, listening to MP3s, reading blogs or sending e-mail is not interacting with a person; it’s interacting with a machine.

“If people feel socially isolated, they need to have more face-to-face interactions with other human beings and in time, will begin to feel happier and more connected to the world and place they live in.”
