Many now have been breathing hot flames at our industry and so I thought it would be time to say my piece this week, after all, we in the business cannot deny that it has been a rough spring for news paper editors and reporters.’’ Ethical scandals great and small have soiled newsrooms from coast to coast. Everyone knows about the profound deceits of Jayson Blair at The New York Times, and the "Writergate" controversy involving Rick Bragg, which led to the departure of the two top editors at the paper. Other misdeeds have ranged from two reporters at The Salt Lake Tribune selling information to The National Enquirer, to a food writer for The Hartford Courant fired for plagiarizing recipes. Are newspaper standards going to pot Some say ethics are worse than ever or are they The past is filled with people running photos of wrestlers in the sports section in exchange for money. In fact, ethical breaches may be less of a problem than 20 years ago. A 1,t of newspapers are cutting corners, but the standards in the business have improved. There were things going on in the past such as reporters writing speeches for politicians they covered and taking bribes from lobbyists -- but people back then were quietly moved out or they left on their own. There was no public ’’display. The industry as a whole is in trouble because, due to media concentration, people at the top are taking out too much money and driving the profits up. The perception is that the real customers are not those who read the paper but those who buy the stock, which damages the profession. Some of this is about resource pressure. Copydesks are overloaded and there is not enough time and more reporters are having to report by phone. The larger the size of newspapers, the less communication between divisions there tends to be. Reporters don’’t climb the stairs anymore, they are highly trained people who sit in their offices and write term papers and won’’t sully themselves going to a greasy housing project or stand out in the rain for a few hours. The economics of journalism along with technological changes has created an atmosphere of trying to get enormous amounts of information as rapidly as possible. The important thing is to make sure the ownership understands the value of a news organization with integrity and every paper needs to slow down and remind ourselves that we have nothing to Sell if the readers don’’t believe us. Technology has meant more information is available at a faster speed ______.

TEXT B Every year, 2,000 American lives are saved by the selflessness of others. These are the bone marrow donors who give the gift of life to patients fighting deadly diseases such as leukemia, lymphoma, and aplastic anemia. That’s the good news. The bad news is that thousands more die each year because not enough people have signed on to the registries that would help the ill find a suitable match for a transplant. Bone marrow or stem-cell transplants are usually a last resort, intended for those whose illnesses have not responded to traditional treatments such as chemotherapy or radiation. How do they work We all store a special type of cell in our bone marrow called stem cells. These primitive cells give rise to the three types of blood cells: red, white and platelets. Everyone’s stem cells have certain genetic characteristics or markers that make them unique from others. Despite this uniqueness, there are some shared characteristics between people. This is important, because a patient’s immune system will reject blood or organs received from someone else if they do not share sufficient similarities. Family members, especially siblings, are always the first to be considered as donors, because there’s a greater chance that the genetic markers on their cells will have enough in common to prevent rejection after transplantation. In many cases, however, a familial match can’t be found and then the search begins for an unrelated donor. These donors typically come from a pool of people who have already signed up on a donor registry in the event that their cells match a needy recipient. Once the lab has verified a match between donor and recipient, the next phase starts. The patient is given radiation or chemotherapy to kill the unhealthy cells. Healthy cells are harvested from the donor — either extracted from the pelvic bones or taken from the arm in a way that is similar to having blood drawn — and prepared in a laboratory. Once they’re ready, they’re given to the patient through a vein — the same way as one would receive a blood transfusion. Once these transplanted donor cells get settled within the patient’s bone marrow, they make the healthy red blood cells, white blood cells and platelets necessary to support life. One of the major problems currently faced by transplant centers is that while bonemarrow transplants can cure more than 70 different diseases, there aren’t enough donors on the registry to treat the more than 3,000 patients awaiting transplants. The National Marrow Donor Program, the largest registry in the country, has approximately 4.8 million adult volunteer donors, but that isn’t nearly enough for the thousands who need transplants. Why isn’t a pool of more than 4 million donors isn’t enough to cover 3,000 needy patients Here’s the reason: in the vast-majority of cases, finding a suitable match isn’t easy. Because we are unique individuals with a variety of ancestral backgrounds and integration patterns, finding someone similar to us is a major task. In the end, it comes down to a numbers game — the more potential donors listed on the registry, the greater a chance of finding a match, especially for those with unusual genetic characteristics. What should be done immediately after the matched donor has been found
