Greening critical care
Martin Chapman, Alison Chapman
Critical Care , 2011, DOI: 10.1186/cc9409
Abstract: Many have argued that the risks to health from climate change are overwhelmingly negative. At the conclusion of the United Nations Climate Change Conference in Copenhagen (COP15), which took place in December 2009, there was no agreed- upon plan of action that would avoid a critical 2% rise in greenhouse gas (GHG) emissions globally. Our international leaders did not step up to the plate; rather, they produced an Accord [1] that will neither solve the problem nor appease the critics [2]. The implications for health [3-5], in light of this, are similar to implications for the economy [6] and the earth's natural systems - they are dire.Our viewpoint is that it is better to be part of the solution than part of the problem, even if there is a dearth of evidence stating that any of the described actions will generate a measureable outcome. When using the term green, we are referring to practices and policies that do not negatively affect our environment. It is hoped that this paper will map out ways to green up an intensive care unit (ICU) and reduce the effect of environmental toxins on our patients, with suggestions targeted at individuals and their institutions. Although sustainable critical care may sound like an oxymoron to many of us, we cannot ignore our responsibilities on the basis that greening an ICU is too difficult. There are steps that can be taken at all levels, setting an example to influence our collective behaviour. If an ICU can go green then there is little excuse for the rest of the hospital not to follow suit.The gauntlet is thrown down.ICUs are not, in our experience, at the forefront of sustainable environmental management. Possibly the only published mention of intensive care and the environment was when, during the Copenhagen Conference, India's Environment Minister said that the Kyoto pact was in 'Intensive Care, if not dead' when negotiations on extending the pact had stalled [7].We are not suggesting that patient care should be in any way com

The Case for a Smoker's License
Simon Chapman
PLOS Medicine , 2012, DOI: 10.1371/journal.pmed.1001342
Abstract: Background to the debate Tobacco continues to kill millions of people around the world each year and its use is increasing in some countries, which makes the need for new, creative, and radical efforts to achieve the tobacco control endgame vitally important. One such effort is discussed in this PLOS Medicine Debate, where Simon Chapman presents his proposal for a “smoker's license” and Jeff Collin argues against. Chapman sets out a case for introducing a smart card license for smokers designed to limit access to tobacco products and encourage cessation. Key elements of the smoker's license include smokers setting daily limits, financial incentives for permanent license surrender, and a test of health risk knowledge for commencing smokers. Collin argues against the proposal, saying that it would shift focus away from the real vector of the epidemic—the tobacco industry—and that by focusing on individuals it would censure victims, increase stigmatization of smokers, and marginalize the poor.

Hemorrhagic shock: a review
Martin Chapman
Critical Care , 2004, DOI: 10.1186/cc2898
Abstract: Damage control surgery in trauma and embolization are certainly useful tools in the control of bleeding.Pharmacological manipulation of the coagulation system is a rapidly expanding field of research. Activated recombinant factor VII (Factor VIIa) is a hemostatic agent originally developed for the hemophilia population, but it is emerging as a very effective way of treating uncontrolled hemorrhage in patients without pre-existing factor deficiencies. A heterogeneous case series of major hemorrhage was reported last year, in which 80% of the cases given Factor VIIa responded with complete or partial cessation of bleeding [2]. Data from the trauma environment with massive bleeding suggest a useful role for Factor VIIa [3], and further studies are ongoing.None declared.H David Reines, Marian Wulf-Gutierrrez and Guillermo Gutierrez.We thank Dr Chapman for his comments on new approaches to control hemorrhage. We agree that conservation of blood and blood products is not just an economic concern, but it is necessary to protect a limited resource and to prevent untoward effects of such products. Our sections on hypertonic saline and the use of blood substitutes were meant to address this issue directly. We limited our discussion to a general discussion of hemorrhagic shock and did not specifically address surgical approaches to the control of bleeding. 'Damage control' and packing is a valid concept in the treatment of severely injured patients with hemorrhage [4]. This approach was frequently used in battlefields, and has become more popular in civilian injury as a method for preventing death from coagulopathy and hypothermia in the operating room. The use of radiological embolization as a technique to control ongoing hemorrhage from solid organs such as the spleen and the liver has also supplemented its use in pelvic hemorrhage. This technique is not necessarily an ideal therapy for patients who are in shock. Operative intervention is still necessary in unstable patients
Taking the perspective of the other seriously? understanding historical argument
Chapman, Arthur;
Educar em Revista , 2011, DOI: 10.1590/S0104-40602011000500007
Abstract: this paper discusses the nature of argument and its role and importance in historical learning. the paper describes pedagogic strategies developed to help school pupils understand what argument is, model how arguments work and think about how arguments can be evaluated. these strategies are explained as generic critical thinking strategies and the article then demonstrates how these strategies can be applied in history education contexts. the strategies that the article describes aim to make the logical relationships that are embodied in arguments clear to students through the use of analogies and active learning strategies that seek, first, to enable students to represent logical relationships in concrete ways and, second, to help students manipulate and explore these relationships.
Mass Generation from Higgs-like Ghosts
Chapman, Scott
High Energy Physics - Phenomenology , 2008,
Abstract: Covariant quantization of gauge theories generally requires the inclusion of Fadeev Popov ghosts in the gauge-fixed Lagrangian. Normally these ghosts have fermionic statistics, but in supersymmetric theories that include fermionic gauge fields, there can also be ghosts with bosonic statistics. Since these ghosts are scalar bosons, they can have vacuum expectation values (VEVs) without violating Lorentz invariance. In particular, for the supersymmetric group SU(2/3), one can choose a gauge with a Higgs-like bosonic ghost potential that is minimized when one of the ghosts develops a VEV. This VEV breaks the SU(2) x U(1) subgroup of SU(2/3) down to U(1) and spontaneously generates vector boson masses, but without the "hierarchy" problems that accompany the Higgs field. SU(2/3) also has an SU(3) subgroup, and unitarity requires that the SU(3) gauge bosons must be confined. Since bosonic ghosts do not exist as particles asymptotically, this kind of theory could be a possible explanation if no Higgs Boson is detected at the LHC.
July 7th 2005 and its Aftermath
Elizabeth Chapman
Liber Quarterly : The Journal of European Research Libraries , 2006,
Abstract: I have been asked to give an account of the effect of the London bombs in July 2005 and how UCL library Services responded. In describing UCL’s libraries I shall deal with service continuity and the effects on staff. I shall then show some of the outcomes of our subsequent review of emergency preparedness and the follow-up we have initiated. I do not intend to provide too much detail on what actually happened but will give some where it sheds light on subsequent review and planning. Despite the grim nature of these events I intend to end with an optimistic note.
