The railroad industry as a whole, despite its brightening fortunes, still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic.
It's a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail.
Shippers who feel they are being overcharged have the right to appeal to the federal government's Surface Transportation Board for rate relief, but the process is expensive, time-consuming, and will work only in truly extreme cases.
But many shippers complain that for heavy bulk commodities traveling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat.
Former Colorado governor Richard Lamm has been quoted as saying that the old and infirm "have a duty to die and get out of the way", so that younger, healthier people can realize their potential.
Physicians — frustrated by their inability to cure the disease and fearing loss of hope in the patient — too often offer aggressive treatment far beyond what is scientifically justified.
Shielded by third-party payers from the cost of our care, we demand everything that can possibly be done for us, even if it's useless.
If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line.
Because they are adjusting to their new bodies and a whole host of new intellectual and emotional challenges, teenagers are especially self-conscious and need the confidence that comes from achieving success and knowing that their accomplishments are admired by others.
However, the typical teenage lifestyle is already filled with so much competition that it would be wise to plan activities in which there are more winners than losers, for example, publishing newsletters with many student-written book reviews, displaying student artwork, and sponsoring book discussion clubs.
Making friends is extremely important to teenagers, and many shy students need the security of some kind of organization with a supportive adult barely visible in the background.
A variety of activities should be organized so that participants can remain active as long as they want and then go on to something else without feeling guilty and without letting the other participants down.
In these activities, it is important to remember that the young teens have short attention spans.
On the contrary, they can help students get a sense of commitment by planning for roles that are within their capabilities and their attention spans and by having clearly stated rules.
Anthropology is a field-study oriented discipline which makes extensive use of the comparative method in analysis.
Therefore, it is important to study humans in all their richness and diversity in a calm and systematic manner, with the hope that the knowledge resulting from such studies can lead humans to a more harmonious way of living with themselves and with all other life forms on this planet Earth.
Tylor defined culture as "…that complex whole which includes belief, art, morals, law, custom, and any other capabilities and habits acquired by man as a member of society".
Thus, the anthropological concept of "culture", like the concept of "set" in mathematics, is an abstract concept which makes possible immense amounts of concrete research and understanding.
The emphasis on data gathered first-hand, combined with a cross-cultural perspective brought to the analysis of cultures past and present, makes this study a unique and distinctly important social science.
Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic, and dispassioned manner that natural scientists use for the study of natural phenomena.
Furthermore, humans have the ability to modify the environment in which they live, thus subjecting all other life forms to their own peculiar ideas and fancies.
For any job search, you should start with a narrow concept — what you think you want to do — then broaden it.
Instead, the best strategy is to use the agent as a kind of tip service to keep abreast of jobs in a particular database; when you get e-mail, consider it a reminder to check the database again.
Hunting for a job late last year, lawyer Gant Redmon stumbled across CareerBuilder, a job database on the Internet.
"I would not rely on agents for finding everything that is added to a database that might interest me," says the author of a job-searching guide.
It's an interactive feature that lets visitors key in job criteria such as location, title, and salary, then e-mails them when a matching position is posted in the database.
Some use them to keep a close watch on the demand for their line of work or gather information on compensation to arm themselves when negotiating for a raise.
"On the day after we send our messages, we see a sharp increase in our traffic," says Seth Peets, vice president of marketing for CareerSite.
When CareerSite's agent sends out messages to those who have signed up for its service, for example, it includes only three potential jobs — those it considers the best matches.
In Manhattan, "there's a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran.
