单选题According to a recent study, a small but growing proportion of the workforce is affected to some degree by a sense of entitlement. Work is less about what they can contribute but more about what they can take. It can lead to workplace dysfunction and diminish their own job satisfaction. I’m not referring to employees who are legitimately dissatisfied with their employment conditions due to, say, being denied fair pay or flexible work practices. I’m talking about those who consistently believe they deserve special treatment and generous rewards. It’s an expectation that exists irrespective of their abilities or levels of performance. As a result of that discrepancy between the privileges they feel they’re owed and their inflated sense of self-worth, they don’t work as hard for their employer. They prefer instead to slack off. It’s a tendency which many scholars believe begins in childhood due to parents who overindulge their kids. This thereby leads them to expect the same kind of spoilt treatment throughout their adult lives. And yet despite how these employees feel, it’s obviously important for their manager to nonetheless find out how to keep them motivated. And, by virtue of that heightened motivation, to perform well. The research team from several American universities surveyed more than 240 individuals. They sampled managers as well as team members. Employee entitlement was measured by statements such as "I honestly feel I’m just more deserving than others". The respondents had to rate the extent of their agreement. Employee engagement, meanwhile, was assessed with statements like "I really throw myself into my work." The findings revealed ethical leadership is precisely what alleviates the negative effects of employee entitlement. That’s because rather than indulging employees or neglecting them, ethical leaders communicate very direct and clear expectations. They also hold employees accountable for their behaviors and are genuinely committed to doing the right thing. Additionally, these leaders are consistent in their standards. They’re also less likely to deviate in how they treat employees. This means, when confronted by an entitled team member, an ethical leader is significantly disinclined to accommodate their demands. He or she will instead point out, constructively and tactfully, exactly how their inflated sense of deservingness is somewhat distorted. They’d then go further to explain the specific, and objective, criteria the employee must meet to receive their desired rewards. This shift away from unrealistic expectations is successful because entitled employees feel more confident that ethical leaders will deliver on their promises. This occurs because they’re perceived to be fair and trustworthy. The researchers, however, exercise caution by warning no one single response is the perfect remedy. But there’s no denying ethical leadership is at least a critical step in the right direction.

单选题There are many stereotypes about the character of people in various parts of the United States. In the Northeast and Midwest, people are said to be closed and private. In the South and West, however, they are often thought of as being more open and hospitable. Ask someone from St. Louis where the nearest sandwich shop is, and he or she will politely give you directions. A New Yorker might eye you at first and after deciding it is safe to talk to you, might give you a rather unexpected explanation. A person from Georgia might be very kind about directing you and even suggest some different places to eat. A Texan just might take you to the place and treat you to lunch. American stereotypes are abundant. New Englanders are often thought of as being friendly and helpful. Southerners are known for their hospitality and warmth. People from the western part of the United States are often considered very outgoing. These differences in character can be traced to different factors such as climate, living conditions, and historical development. When travelling from place to place, Americans themselves are often surprised at the differing degrees of friendliness in the United States.
