Getting into the Cochrane Library for free

Cochrane Collaboration

Today, I was following up a press release about a review of clinical trials. The analysis suggests that the cannabinoid receptor antagonist rimonabant could help people quit smoking without gaining weight.

The research was published today in the Cochrane Database of Systematic Reviews, a repository of clinical trials data and analyses that is an invaluable resource for those in healthcare, medical research, patient advocacy groups and patients and their carers, the medical media, and others. Anyway, more on the actual story later this month in the summer issue of Reactive Reports.

Now whenever I have needed access to information held in the Cochrane Library database previously, I’ve simply gone through the usual journalist’s route to get at such nuggets. However, the press release pointed out that Cochrane Library publications are also available entirely free of charge to particular groups and to members of the public depending on where you are.

Guest users can access abstracts for all Reviews in the database, but if you live in any of the following places, there are special access points through which you can get publications for free from the Cochrane Collection (either that or the country tag of your computer’s IP address gives you free access:

Australia
New Zealand
Denmark
England
Finland
Ireland
Norway
Scotland
Spain
South Africa
Sweden
Wales
Saskatchewan
Wyoming

So, now you know how to get into the Cochrane Library for free. Of course, if you are in Michigan, Montreal or Moscow you may have to move house.

When Blogging Gets You Fired

Blogger fired

You wouldn’t think that writing up a few random thoughts in a blog could get anyone into trouble, would you? Obviously, if you’re making libelous statements then some day soon you are going to be sued, allegedly. But, most of us are sensible enough not to slander anyone in print, in person, or online, aren’t we?

No, the issue to which I am alluding to is the case where you, as a blogger, overhear some juicy gossip, perhaps not all the details, but enough to make you respond strongly enough that you want to tell the world. You do a short write-up, expressing your opinions about the turn of events as you heard them, you mention no one by name, make no direct connections to the place or time of the happening, and do all this in a personal blog.

Next thing you hear, someone connected with the gossip has made the connection, found out where you work and emailed a serious complaint, cc’ing your boss. The complaint alludes to an abuse of privacy laws, trust, and customer-client confidentiality. You panic, confess all to your boss, a meeting is called with the bosses and HR and before you know what’s hit you, you’re fired.

There have been several instances of medical professionals and others being barred from writing blogs recently. There is usually a serious conflict of interest between the public discussion of medical matters and the confidentiality inherent in the Hippocratic Oath. It’s the same when professionals present case studies in their trade publications, particularly if they mention any two of the following, portable vacuum cleaners, potatoes, genitals, the rectum, or hot-tubs, in the same sentence.

Seriously though, what can you, as a compulsive blogger, do to minimise the risk of employment cessation? Here are my top tips, which you can take or leave, but which do not represent secure advice in the legal sense but merely some common sense thoughts.

First off, decide whether the benefits of blogging and the risks it might entail actually outweigh the benefits of gainful employment. I suspect 99 times out of 100 they won’t, unless you’ve optimised your ads really, really well.

Second, double check your employment contract and any professional oaths you take to make sure there is no conflict of interest or that you are not automatically precluded from revealing your inner thoughts to the public.

Third, do not under any circumstances use your employer’s computing equipment, services, web connection, email, telephone or anything else for personal use and particularly not in relation to your blog, unless you have explicit permission. Even then, be very cautious of blogging from a work IP. They could string you up on a technicality if you even used the phone once to call your grandmother. In fact, they could fire you for all kinds of reasons on this one whether you’re blog breaks the rules or not.

Fourth, ensure your blog is entirely personally run, owned, and in no way tied to your employer. (Also see item 3 in this regard).

Fifth, make sure that what you are saying is legal and does not defame anyone, it’s a basic rule of journalism, and if bloggers are staking a claim on that realm, then they ought to learn the rules, for their own safety.

Finally, a bonus tip. Go back to point one and decide whether running a blog to vent off steam is really a better outlet than a trip to the pub with friends where you can ruminate to your heart’s content with (usually) no fear of losing your job. Ask yourself, does my blog shed a good light on me as a professional or my employer as the entity paying my bills?

In a recent report from American Medical News, some physician-bloggers have found that what they wrote could be used against them. That doesn’t mean you have to stop, or never start, says the report. But, people do get sacked for running blogs and saying the wrong thing, at the wrong time.

Incidentally, this post is NOT autobiographical. I didn’t. Honest. But, I’m not going to embarrass the blogger who did get fired this week, having essentially failed to adhere to those safe blogging rules.

Meanwhile, more public cases of blog firings that show this is nothing new. Read ’em and weep:

Of Blogging and Unemployment

5 Reasons Blogging Leads to the Unemployment Line (You’re Fired!) – Adds, the caveat that you must sure you’re not late for work or slacking cos you’re blogging.

Be warned though, not blogging can get you fired too!

And, it’s not just blogging that could get you into trouble, your boss could “own” your Facebook, MySpace, Twitter, Pownce, etc accounts if you even mentioned running one at work, under your contract of employment. Just as a research chemist who invents a new life-saving drug, attempts to take out a patent in their own name will most likely discover that anything they produce while employed will defer to the intellectual property of their employer. Unless their contract contains a get out clause or an IP sharing paragraph, they will not profit from their invention even if they did it in a home lab.

The same might apply to your StumbleUpon account, your Digg page, your del.icio.us bookmarks, and links you share with others using the Share This plugin displayed below.

Harry Potter and the Terrorist Threat

Harry potter and the deathly hallows

Could the UK government’s response to the terrorist threat since 9/11 be the basis of plots and story lines in the Harry Potter series of books? Judith Rauhofer of the University of Central Lancashire believes so and has carried out a study of JK Rowling’s fictional accounts of the exploits of the child wizard with the infamous scar. She has found several subtle parallels in the books written since September 11, 2001, with contemporary society and suggests that the allegorical nature of these novels could underpin much of their appeal to adult readers.

Since the publication of the fourth book, “Harry Potter and the Goblet of Fire”, the publishers, Bloomsbury, has acknowledged that a large part of the readership is among adults, by publishing an adult edition alongside the children’s version. Many commentators suspect that one possible rationale for this is to allow adults to read the book in public without embarrassment.

Jon Howells of Waterstone’s told me that, “Based on our pre-order statistics we estimate that some 45 per cent of Harry Potter book 7 sales will be of the adult edition, which is up on about 23 per cent for the last book.” Book 7 – Harry Potter and the Deathly Hallows – goes on sale Saturday 21st July.

According to Rauhofer, book five in the series was the first Harry Potter book to be written entirely after the terrorist attacks in New York City, Pennsylvania, and Washington. “Until then, the Harry Potter series could be seen as nothing more than a simple story of good versus evil,” says Rauhofer. But, after that, “JK Rowling’s work evolved into more of a social commentary on current events.”

Rauhofer believes that with the Harry Potter series Rowling has created a parallel world highlighting many of the steps taken by the British government, which she says are mostly unfair and unjustifiable, in the name of the war on terror. For instance, in the fifth book, “Harry Potter and the Order of the Phoenix”, all wizards are issued with emergency pamphlets. “Most people who received the UK government’s ‘Preparing for an-emergency’ pamphlet through their letterbox in 2004 will recognise the irony of Rowling’s plot detail here,” says Rauhofer.

Several key plot features hint at parallels between the wizard world and the so-called “muggle” world of humans, says Rauhofer. The marginalising of an ethnic group, for instance, by the muggles themselves, identity issues with Death Eaters masquerading as others, detention without trial of Knight Bus conductor Stanley Shunpike on suspicion of Death Eater activity, interception of Arthur and Molly’s post while in The Burrow in the name of safety, and many other examples.

“Rowling’s description of an alternative society and its government traces recent events in contemporary society,” Rauhofer adds, “The political thread going through the series largely focuses on the way in which the Ministry of Magic deals with Lord Voldemort’s return.” If Voldemort, whom of course should not be named, is the terrorist threat in disguise, then the anti-Voldemort security measures taken by the Wizards could be seen to reflect various legal and political changes that have occurred in the UK since 9/11.

Of course, it could simply be that, like countless books before it, readers find ways of looking between the lines to see hidden messages that are simply not there. Unfortunately, JK Rowling is rather busy this week and was unavailable for comment at the time of writing.

Chemical Crocodile Clips

I hate having to download standalone video players to enable playback of video content. Google Videos/Youtube are both guilty, although obviously you can view online, but then you have to have an internet connection to do that unless you save the file to your hard drive and download the player…

Crocodile Clips provides simple simulation software and, you’ve guessed it, they have their own proprietary player. But, I can excuse them, because their player is not a simple video rendering application but a simulator that allows educators and students alike to work with data and generate simulations of a whole range of processes from titration to animation. For ChemSpy.com users, the chemistry simulations and tutorials will probably be of most interest.

With the snappy Crocodile Chemistry, you get a simulated chemistry laboratory where you can model experiments and reactions, without all the hassle of fume cupboards and safety goggles. Drag chemicals, equipment and glassware from the toolbars at the side of the screen, and combine them as you wish. Choose whatever quantities and concentrations you like: reactions are modelled accurately as soon as you mix the chemicals. Plot graphs to analyse data from your experiment, and view mechanisms using 3D animations.

Moreover, if you really cannot face downloading yet another applet for viewing something, then they also have a section on pre-simulated videos ready for showing that are targeted at training potential users, but only if you’re online and only in their proprietary video format.

Filter Paper Lead by Atomic Absorption Spectrometry

LeadA single drop of blood absorbed on to a filter paper is all that is needed for a new test for lead, based on solid sampling-graphite furnace atomic absorption spectrometry (SS-GFAAS). The minimally-invasive method would allow many more people, and children in particular, to be tested quickly and safely for exposure to lead and to facilitate follow-up industrial safety incidents involving the neurotoxic metal.

I wrote about this research over on the SpectroscopyNOW.com site, and asked team leader Martin Resano about the applications of his test in epidemiological studies. Apparently, there is already a well established approach to testing new-borns based on a filter paper test. However, he told me that the situation is very different, there is some reluctance in the clinic to adopt filter paper tests.

“Many people in the clinical community are against the filter paper test for Pb,” Resano told me, “Precisely, the goal of our work is to show that, if a suitable direct solid sampling technique such as SS-GFAAS is used (thus avoiding the tedious and contamination-prone step of digestion of the papers), it is feasible to achieve satisfactory results for Pb blood using the filter paper test.”

Arctic droughts, plastic breakdown, and liquid telescopes

This month’s intute Spotlight from David Bradley is now available online:

Telescopic lunar liquid: A liquid reflector for a vast Newtonian telescope to be based on the surface of the Moon is being developed by scientists in Canada, UK, and US. The new type of telescope could provide the clearest views yet of ancient parts of the Universe.

Arctic drought – Frozen Arctic ponds that have persisted for millennia are drying out during the polar summer, according to evidence from Canadian scientists. Marianne Douglas of the Canadian Circumpolar Institute at the University of Alberta together with John Smol, of Queen’s University, have studied these shallow ponds that dot the Arctic landscape for more than two decades. Changes in such environmental features provide an important indication of how particular regions are being affected by climate change. Douglas and Smol have analysed 24 years of detailed data, including water quality and water levels from about forty Arctic ponds. The data represents the longest record of systematic fresh water monitoring in the high Arctic.

Plastic breakdown – As if to show just how diverse the properties and applications of ionic liquids can be, a new era in recycling of plastics is fast approaching thanks to scientists in Japan. The researchers have developed a process based on ionic liquids that can depolymerise plastic materials back into the component monomers from which they were originally made. The team says the method can then be used to convert waste polymers into new high-quality plastics.

Viz Comic to Win Science Writing Award

Viz comic

When I was a kid growing up in the North East of England, the literature was limited, but there was one item of essential reading: Viz Comic. This crudely produced and photocopied newsheet used to worm its way from brothers Chris and Simon Donald’s bedroom to our school with its vulgar, laugh out loud humour and top tips. LetterBox was key to its success providing, as does any modern blog, a conduit through which readers could vent their spleen, offer advice, and generally answer the preceding question in the very same issue as if by magic.

Why am I discussing Viz? Well, in recent issues they have taken to satirizing various prominent figures from the world of science. The current issue provides a scatalogical skit of the biggest name in amateur astronomy this side of the Pond – Sir Patrick Moore – while the last issue picked up on Richard Dawkins’ vehement atheism and apparent anti-religious stance. In the story, Dawkins creates a giant artificial cardiac organ and then finds it impossible to prevent a tiny “Jesus Christ” from gaining access. Thus having allowed “Jesus to enter his heart”, Dawkins is forcefully ejected from the Royal Science Organisation by a group of bearded gents in stove-pipe hats and tail coats. Did I say Viz was not only crude but can also be incredibly offensive?

If memory serves correctly, at least one of the original Viz team studied microbiology at University, although that could be a blatant lie as Chris Donald failed his A-levels and there is scant information on brother Simon that mentions any science connection either. However, there have been, despite appearance and the presence of Rude Kid, Roger’s Profanisaurus (NSFW), Johnny Fartpants, and Black Bag, several instances of rather technologically and scientifically insightful parodies and spoofs in the Comic over the years (it began life in 1979, when I was still at school, by the way).

One fellow science writer, who shall remain anonymous here, has gone so far as to suggest that Viz should, on the basis of recent activity viz. Prof Dawkins and Sir Patrick, should enter the ABSW science writing awards. The competition is tight, but you never know, they may stand a chance in the “science in society” section. I just wonder whether society is ready to accept Viz as a pillar of the scientific literature.

Quit smoking avoid the munchies

Rimonabant structureCould a drug that blocks the brain’s cannabinoid (CB1) receptors help people stop smoking without gaining weight? According to a Cochrane Systematic Review, just 20 mg of CB1 antagonist rimonabant each day helps quitters and also helps them avoid the munchies.

Smoking tobacco sends nicotine into the blood stream, and this chemical disrupts the endocannabinoid system, part of the hormonal control mechanism in the brain that controls energy balance and food intake. Over time the body alters the nature of its energy mechanism to compensate for this effect. When you quit smoking, the nicotine withdrawal disturbs this mechanism, causing withdrawal symptoms and leaving a person prone to put on weight.

Unfortunately for smokers who want to quite and stay slim, rimonabant is yet to be approved for this use in the USA or Europe.
