Joe Mangano's Credibility Takes Another Body Blow

This time, the sledgehammer is delivered courtesy of Barbara Feder Ostrov's Health Journalism Blog. Like plenty of other folks, she was shocked at Joe Mangano's claims -- ones that he backed off from when under questioning from MedPage Today -- so she talked to some long-time medical journalists.

Here's what Ivan Oransky of Reuters Health had to say about Mangano's research:
I do use impact factor to judge journals, while accepting that it's an imperfect measure that is used in all sorts of inappropriate ways (and, for the sake of full disclosure, is a Thomson Scientific product, as in Thomson Reuters). I find it helpful to rank journals within a particular specialty.

[...]

I looked up the journal in question, and it's actually ranked 45th out of 58 in the Health Policy and Services category (in the social sciences rankings) and 59th out of 72 in the Health Care Sciences & Services category (in the science rankings).
Here's Gary Schwitzer of Health News Review:
Journalists who live on a steady diet of journal articles almost by definition promote a rose-colored view of progress in research if they don't grasp and convey the publication bias in many journals for positive findings. Negative or null findings may not be viewed as sexy enough. Or they may be squelched prior to submission. While perhaps not a factor in this one case, it nonetheless drives home the point to journalists about the need to critically evaluate studies.
I'm afraid I have more bad news for Mangano. Who's going to tell Christie Brinkley?

Int J Health Serv is a rather obscure journal, which has been used by Mangano, Sherman, and some of Mangano's old colleagues (e.g., Sternglass and Gould) for a couple of decades or so to publish dubious papers such as this.

It looks like Mangano has a sympathetic editor, who is willing to set up his papers for softball reviews (so-called "Pal Review," rather than rigorous peer review) and who is willing to publish just about anything that Mangano gives him.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why Nuclear Plant Closures Are a Crisis for Small Town USA

Nuclear plants occupy an unusual spot in the towns where they operate: integral but so much in the background that they may seem almost invisible. But when they close, it can be like the earth shifting underfoot.

Lohud.com, the Gannett newspaper that covers the Lower Hudson Valley in New York, took a look around at the experience of towns where reactors have closed, because the Indian Point reactors in Buchanan are scheduled to be shut down under an agreement with Gov. Mario Cuomo.


From sea to shining sea, it was dismal. It wasn’t just the plant employees who were hurt. The losses of hundreds of jobs, tens of millions of dollars in payrolls and millions in property taxes depressed whole towns and surrounding areas. For example:

Vernon, Vermont, home to Vermont Yankee for more than 40 years, had to cut its municipal budget in half. The town closed its police department and let the county take over; the youth sports teams lost their volunteer coaches, and Vernon Elementary School lost th…
