The article suggests that the efforts of the British government to reform the National Health Service (NHS) are under threat from other factors that aim to hasten competition in the health service, according to the British Medical Association (BMA) in October 2010. As mentioned in the government's White Paper "Equity and Excellence: Liberating the NHS," reform efforts will allow more control to patients and frontline clinicians and promote stronger attention on public health. The other arguments of BMA are further explained by chairman Hamish Meldrum.

The British Government appointed a departmental committee to review anti-homosexuality laws in 1954 following a marked increase in the number of arrests for homosexuality after World War II. The committee invited the British Medical Association (BMA) and other institutions to provide scientific and medical evidence relating to homosexuality. In 1954, the BMA established the Committee on Homosexuality and Prostitution to present its view on how the law impacted upon homosexuals and society. This paper analyses the BMA's attitudes to homosexuality by examining its submission to the Departmental Committee. Whilst the BMA supported implicitly the decriminalization of certain homosexual acts, it remained strongly opposed to homosexuality from a moral perspective and insisted that it was an illness. It is concluded that the BMA's submission was driven primarily by a desire to control the "unnatural deviant" behavior of homosexuals and to protect society from that behavior rather than to protect homosexuals.

The article provides information about the development of the journal "Archives of Disease in Childhood." The British Medical Association (BMA) has founded the journal in 1926. In 1977, the BMA and British Pediatric Association (BPA) became partners and shared profits and losses with up to 800 copies given to BPA members. Years passed by, the journal has adapted new technology and become more friendly to the reader. It has embraced standard approaches to assessment and criticisms of papers.

Meteorological ensemble members are a collection of scenarios for future weather issued by a meteorological center. Such ensembles nowadays form the main source of valuable information for probabilistic forecasting which aims at producing a predictive probability distribution of the quantity of interest instead of a single best guess point-wise estimate. Unfortunately, ensemble members cannot generally be considered as a sample from such a predictive probability distribution without a preliminary post-processing treatment to re-calibrate the ensemble. Two main families of post-processing methods, either competing such as the BMA or collaborative such as the EMOS, can be found in the literature. This paper proposes a mixed-effect model belonging to the collaborative family. The structure of the model is formally justified by Bruno de Finetti's representation theorem which shows how to construct operational statistical models of ensemble based on judgments of invariance under the relabeling of the members. Its interesting specificities are as follows: (1) exchangeability contributes to parsimony, with an interpretation of the latent pivot of the ensemble in terms of a statistical synthesis of the essential meteorological features of the ensemble members, (2) a multiensemble implementation is straightforward, allowing to take advantage of various information so as to increase the sharpness of the forecasting procedure. Focus is cast onto normal statistical structures, first with a direct application for temperatures, then with its very convenient Tobit extension for precipitation. Inference is performed by expectation maximization (EM) algorithms with both steps leading to explicit analytic expressions in the Gaussian temperature case, and recourse is made to stochastic conditional simulations in the zero-inflated precipitation case. After checking its good behavior on artificial data, the proposed post-processing technique is applied to temperature and precipitation ensemble forecasts produced for lead times from 1 to 9 days over five river basins managed by Hydro-Québec, which ranks among the world's largest electric companies. These ensemble forecasts, provided by three meteorological global forecast centers (Canadian, USA and European), were extracted from the THORPEX Interactive Grand Global Ensemble (TIGGE) database. The results indicate that post-processed ensembles are calibrated and generally sharper than the raw ensembles for the five watersheds under study. Supplementary materials accompanying this paper appear on-line. [ABSTRACT FROM AUTHOR]

This paper examines the experiences of women in one professional organisation - the British Medical Association in Australia - during a significant period in the development of such bodies. In doing so it offers an opportunity to consider the relationship between professional societies and the construction of a gendered profession. For the medical profession in particular the time-frame of this study, from the 1880s to the 1930s, has been regarded by scholars as especially important. In this period various features of medical professionalism came to prominence: the status and authority of doctors, the processes of formally registering medical credentials, and the scope and cohesiveness of professional associations. Taking the third of these themes, the current paper extends previous analyses by uniting gender with history and medicine as the central point of examination, in order to evaluate the changing and contested positions of women within the profession. In this way we not only demonstrate how the history of professional societies can reveal the diverse beliefs and shifting priorities of their members, but also contribute to explaining the remarkable persistence of gendered differences in the medical profession.

The paper considers the recently published British Medical Association Guidance on ethical issues arising in relation to rationing of treatment during the COVID-19 Pandemic. It considers whether it is lawful to create policies for the rationing and withdrawal of treatment, and goes on to consider how such policies might apply in practice. Legal analysis is undertaken of certain aspects of the Guidance which appear to misunderstand the law in respect of withdrawing treatment. [ABSTRACT FROM AUTHOR]

In low-seismicity areas such as Europe, seismic records do not cover the whole range of variable configurations required for seismic hazard analysis. Usually, a set of empirical models established in such context (the Mediterranean Basin, northeast U.S.A., Japan, etc.) is considered through a logic-tree-based selection process. This approach is mainly based on the scientist's expertise and ignores the uncertainty in model selection. One important and potential consequence of neglecting model uncertainty is that we assign more precision to our inference than what is warranted by the data, and this leads to overly confident decisions and precision. In this paper, we investigate the Bayesian model averaging (BMA) approach, using nine ground-motion prediction equations (GMPEs) issued from several databases. The BMA method has become an important tool to deal with model uncertainty, especially in empirical settings with large number of potential models and relatively limited number of observations. Two numerical techniques, based on the Markov chain Monte Carlo method and the maximum likelihood estimation approach, for implementing BMA are presented and applied together with around 1000 records issued from the RESORCE-2013 database. In the example considered, it is shown that BMA provides both a hierarchy of GMPEs and an improved out-of-sample predictive performance. [ABSTRACT FROM AUTHOR]

This paper investigates the role of real estate-specific uncertainty in predicting the conditional distribution of US home sales growth over the monthly period of 1970:07 to 2017:12, based on Bayesian Model Averaging (BMA) to account for model uncertainty. After controlling for standard predictors of home sales (housing price, mortgage rate, personal disposable income, unemployment rate, building permits, and housing starts), and macroeconomic and financial uncertainties, our results from the quantile BMA (QBMA) model show that real estate uncertainty has predictive content for the lower and upper quantiles of the conditional distribution of home sales growth.

In this paper, inspired by the biology migration phenomenon, which is ubiquitous in the social evolution process in nature, a new meta-heuristic optimization paradigm called biology migration algorithm (BMA) is proposed. This optimizer consists of two phases, i.e., migration phase and updating phase. The first phase mainly simulates how the species move to new habits. During this phase, each agent should obey two main rules depicted by two random operators. The second phase mimics how some species leave the group and new ones join the group during the migration process. In this phase, a maximum number of iterations will be set to predetermine whether a current individual should leave and be replaced by a new one. Simulation results based on a comprehensive set of benchmark functions and four real engineering problems indicate that BMA is effective in comparison with other existing optimization methods.

Accurate and reliable long-term runoff forecasting is very important for water resource system planning and management. This study utilized three data-driven models to simulate and forecast the monthly runoff series of the Huangzhuang hydrological station from 1981 to 2017. To improve the accuracy and reduce the uncertainty, two model averaging techniques were applied to merge forecast results of the different models, and 90% confidence intervals were derived using Monte Carlo sampling. Several indices were used to evaluate the results of three data-driven models and two model averaging techniques. Among the many discoveries in this paper, the following stand out: (i) in general, the random forest (RF) algorithm presented nearly the same accuracy as did the artificial neural network (ANN) algorithm, and both were superior to the support vector machine (SVM) method; however, none of the models consistently provided the best result in all months; (ii) the comparison of the deterministic results indicated that Copula-Bayesian model averaging (BMA) exhibited smaller errors than did BMA, especially for the points whose uniform quantiles ranged within (0.125, 0.35) and (0.5, 0.625); and (iii) in most cases, the 90% confidence interval of the Copula-BMA scheme had higher containing ratio values, smaller average relative bandwidth values in the high-flow months, and smaller average relative deviation amplitudes than did BMA.

Accurate and reliable probabilistic forecasts of hydrological quantities like runoff or water level are beneficial to various areas of society. Probabilistic state‐of‐the‐art hydrological ensemble prediction models are usually driven with meteorological ensemble forecasts. Hence, biases and dispersion errors of the meteorological forecasts cascade down to the hydrological predictions and add to the errors of the hydrological models. The systematic parts of these errors can be reduced by applying statistical postprocessing. For a sound estimation of predictive uncertainty and an optimal correction of systematic errors, statistical postprocessing methods should be tailored to the particular forecast variable at hand. Former studies have shown that it can make sense to treat hydrological quantities as bounded variables. In this paper, a doubly truncated Bayesian model averaging (BMA) method, which allows for flexible postprocessing of possibly multimodel ensemble forecasts of water level, is introduced. A case study based on water levels for a gauge of river Rhine reveals a good predictive skill of doubly truncated BMA compared both to the raw ensemble and the reference ensemble model output statistics approach. Using rolling training periods, BMA considerably outerperforms ensemble model output statistics. However, this gap shrinks drastically when using analog‐based training periods. Key Points: Doubly truncated Bayesian model averaging (BMA) is introduced as a postprocessing methodThe proposed BMA approach, which is tailored to bounded variables, outperforms an ensemble model output statistics reference methodThe benefit from BMA is considerable for rolling training periods but shrinks drastically for analog‐based training periods [ABSTRACT FROM AUTHOR]

The demand for organs prompted the first use of elective ventilation in the UK in the 1990s. Recently the shortfall in supply of organs has once again prompted calls for elective ventilation to be instituted even in patients who are not brain dead. This paper proposes that the term 'elective' ventilation is a misnomer and the term non-therapeutic ventilation (NTV) should be used instead. It is further argued that the practice of NTV in cases of severe stroke is unethical and has the potential of causing a variety of harms to the patient, their relatives, and the healthcare professionals working in transplant teams and this may result in a backlash of reductions in the number of organ donations.

Public policy on alcohol in the UK relies on health promotion campaigns that encourage individuals who misuse alcohol to make healthier choices about their drinking. Individuals with alcohol-dependence syndrome have an impaired capacity to choose health. As a result, individuals with the worst alcohol misuse problems lie largely outside the reach of choice-based policy. However, such policy has been widely criticized and efforts to reform it are underway. This paper argues that the British Medical Association's recent attempt to improve policy on alcohol in the UK by introducing strategies which have been shown to control drinking within populations still gives insufficient attention to alcohol dependence. This is because it fails accurately and consistently to characterize alcohol dependence and gives insufficient attention to the social challenges it presents. [ABSTRACT FROM AUTHOR]

This paper challenges the view that British medical parliamentarians were a rare breed whose limited presence was felt most during the late-Victorian period. Focused on the interwar "movement" for a medical lobby in Parliament, it identifies 159 medical candidates (of whom 72 were elected). It traces the motivations of the British Medical Association in promoting this movement, and shows how the BMA's goals were subverted in part by the identity interests and agendas of the medical men and women who sought election. The paper also highlights some of the alternative political strategies that the profession attempted to use to promote its interests. In addition to providing a window on the culture and politics of British medicine in the interwar period, it explains why the place of doctors in the House of Commons cannot be seen as contributing to the emergence of professional society as defined by Harold Perkin.

It is argued that the current policy of the British Medical Association (BMA) on conscientious objection is not aligned with recent human rights developments. These grant a right to conscientious objection to doctors in many more circumstances than the very few recognised by the BMA. However, this wide-ranging right may be overridden if the refusal to accommodate the conscientious objection is proportionate. It is shown that it is very likely that it is lawful to refuse to accommodate conscientious objections that would result in discrimination of protected groups. It is still uncertain, however, in what particular circumstances the objection may be lawfully refused, if it poses risks to the health and safety of patients. The BMA's policy has not caught up with these human rights developments and ought to be changed. [ABSTRACT FROM AUTHOR]

The Mental Capacity Act 2005 introduced a statutory framework for advance decisions, thus promoting autonomous healthcare decision making in advance of loss of capacity. In order to be valid and applicable, and so binding on healthcare professionals, advance decisions refusing treatment ( ADRT) must specify treatments to be refused and the circumstances of refusal. Recent case-law indicates that a high level of specificity is required for advance refusals of life-sustaining treatment and, in contrast to a presumption of capacity for contemporaneous decisions, in some circumstances capacity must be demonstrated at the time of making the advance decision. In comparison with the 'stringent' requirements for ADRT, the more generic Advance Care Planning ( ACP) is gaining more prominence in end of life decision making. The paper explores recent case-law and its impact on the effectiveness of ADRT in practice and compares with ACP. [ABSTRACT FROM AUTHOR]

Research into bone marrow adiposity (BMA) has expanded greatly since the late 1990s, leading to development of new methods for the study of bone marrow adipocytes. Simultaneously, research fields interested in BMA have diversified substantially. This increasing interest is revealing fundamental new knowledge of BMA; however, it has also led to a highly variable nomenclature that makes it difficult to interpret and compare results from different studies. A consensus on BMA nomenclature has therefore become indispensable. This article addresses this critical need for standardised terminology and consistent reporting of parameters related to BMA research. The International Bone Marrow Adiposity Society (BMAS) was formed in 2017 to consolidate the growing scientific community interested in BMA. To address the BMA nomenclature challenge, BMAS members from diverse fields established a working group (WG). Based on their broad expertise, the WG first reviewed the existing, unsystematic nomenclature and identified terms, and concepts requiring further discussion. They thereby identified and defined 8 broad concepts and methods central to BMA research. Notably, these had been described using 519 unique combinations of term, abbreviation and unit, many of which were overlapping or redundant. On this foundation a second consensus was reached, with each term classified as " to use " or " not to use." As a result, the WG reached a consensus to craft recommendations for 26 terms related to concepts and methods in BMA research. This was approved by the Scientific Board and Executive Board of BMAS and is the basis for the present recommendations for a formal BMA nomenclature. As an example, several terms or abbreviations have been used to represent "bone marrow adipocytes," including BMAds, BM-As , and BMAs. The WG decided that BMA should refer to "bone marrow adiposity"; that BM-A is too similar to BMA ; and noted that "Ad" has previously been recommended to refer to adipocytes. Thus, it was recommended to use BMAds to represent bone marrow adipocytes. In conclusion, the standard nomenclature proposed in this article should be followed for all communications of results related to BMA. This will allow for better interactions both inside and outside of this emerging scientific community. [ABSTRACT FROM AUTHOR]

In this paper, a hybrid wind power forecasting approach based on Bayesian model averaging and Ensemble learning (BMA-EL) is proposed. Firstly, SOM clustering and K-fold cross-validation are used to generate multiple sets of the training subsets with the same distribution from the training set of meteorological data to increase the difference of the input samples of the base learners. These training subsets are imported into three base learners, i.e. BPNN, RBFNN, and SVM, to train the model. Then, the BMA combining strategy is trained based on the outputs of the three base learners on the validation set. Finally, the test set is combined by the BMA through the outputs of the three base learners to obtain the WPF results. By comparing the simulation error and curve between the base learner and other literature approaches, our proposed method can accurately and reliably forecast the wind power outputs under different meteorological conditions, with higher precision and reliability. • SOM clustering and k-fold cross-validation are combined on the training set. • Different base learners and diverse training subsets improve EL-model's performance. • The wind power forecasting approach based on BMA-EL has better prediction results.

Many jurisdictions require cyclists to wear bicycle helmets. The UK is currently not one of these. However, an increasing number of interest groups, including the British Medical Association, want to change the status quo. They argue that mandatory cycle helmet laws will reduce the incidence of head injuries and that this will be both good for cyclists (because they will suffer fewer head injuries) and good for society (because the burden of having to treat cyclists suffering from head injuries will be reduced). In this paper we argue against this position. We suggest that cycle helmets may not be especially effective in reducing head injuries and we suggest that the imposition of such a restrictive law would violate people's freedom and reduce their autonomy. We also argue that those who accept such a restrictive law would be committed to supporting further legislation which would force many other groups -- including pedestrians -- to take fewer risks with their health. We conclude that cycle helmet legislation should not be enacted in the UK unless, perhaps, it is restricted to children. [ABSTRACT FROM AUTHOR]

Current General Medical Council (GMC) guidelines state that any doctor who does not wish to carry out a non-therapeutic circumcision (NTC) on a boy must invoke conscientious objection. This paper argues that this is illogical, as it is clear that an ethical doctor will object to conducting a clinically unnecessary operation on a child who cannot consent simply because of the parents' religious beliefs. Comparison of the GMC guidelines with the more sensible British Medical Association guidance reveals that both are biased in favour of NTC and subvert standard consent procedures. It is further argued that any doctor who does participate in NTC of a minor may be guilty of negligence and in breach of the Human Rights Act. In fact, the GMC guidance implies that doctors must claim conscientious objection if they do not wish to be negligent. Both sets of guidelines should be changed to ensure an objective consent process and avoid confusion over the ethics of NTC. [ABSTRACT FROM AUTHOR]

The very efficacy of antisepsis put its inventor, Joseph Lister, in a difficult diplomatic position—one that required him not to attack those who, for whatever misguided reason, refused to adopt the new technique. Lister’s writings are notably understated, and it is in keeping with their humility of expression that he does not orate against those who resisted antisepsis at such cost to their patients [ABSTRACT FROM AUTHOR]

Abstract The paper considers how attributes and skills fundamental to the information profession may be applied to the development and management of Web-based services and resources. It also looks at the need for the acquisition of new skills as part of a continuing professional development programme. The report considers the changing role of the Webmaster and the implications this might have in terms of the role of information professionals. To offer a practical example, from within the healthcare sector, the article goes on to describe the development of BMA Library Online. This is the BMA Library’s own suite of Web-based information services and resources for personal members, institutional members and staff. The library’s own Web team has been responsible for the development and maintenance of BMA Library Online. To conclude, the paper looks forward to future possibilities for information professionals as Web developers and at how this might be influenced by changes in the Webmaster role. It is crucial that skills and expertise are shared as the roles that go to make up a Webmaster or Webmaster team continue to merge and evolve, and with the possible wider distribution of provision of Web content within organizations.

In this paper, the study area was the Inner Niger Delta (IND) in Mali, West Africa. The IND is threatened by climate change, increasing irrigation, and dam operations. 2D hydrodynamic modelling was used to simulate water levels, discharge, and inundation extent in the IND. Three different digital elevation models (DEM) (SRTM, MERIT, and a DEM derived from satellite images were used as a source of elevation data. Six different models were created, with different sources of elevation data and different downstream boundary conditions. Given that the performance of the models varies according to the location in the IND, the variable under consideration and the performance criteria, Bayesian Model Averaging (BMA) was used to assess the relative performance of each of the six models. The BMA weights, along with deterministic performance measures, such as the Nash Sutcliffe coefficient (NS) and the Pearson's correlation coefficient (r), provide quantitative evidence as to which model is the best when simulating a particular hydraulic variable at a particular location. After the models were combined with BMA, both discharge and water levels could be simulated with reasonable precision (NS > 0.8). The results of this work can contribute to the more efficient management of water resources in the IND. [ABSTRACT FROM AUTHOR]

This article revisits the nineteenth-century debate about medical quackery in Britain, to examine its implications for the history of modern advertising. It makes two related claims. First, the prevalent view of advertising as a field prone to exaggeration, often taken as obvious, has a legal history. The circumstances of the quackery debate led to a legal elaboration and formalization of views of advertising as an epistemologically doubtful but not illegal field. Second, advertising's status as exaggeration was part of a legally supported cultural division of labour – or legal boundary work, which carved differentiated roles for science and the market in modern Britain whereby science was increasingly defined by restraint, and the market by its lack. The analysis examines the implications, while also offering new insights on the role of law in the history of quackery, and examining untapped sources, particularly a set of libel cases that developed a legal definition of quackery.
