Rasmussen number greater than one

This essay describes the ramifying influence of Jens Rasmussen, illustrating how his work lives on through people whom he has influenced, even though they may have never directly collaborated. I approach this in three ways: a social network analysis of the 'Rasmussen number' (an analogue of the Erdös number); and two citations network analyses based on different search domains and different network structures.

Agricultural anaerobic digestion power plants in Ireland and Germany: policy and practice

The process of anaerobic digestion (AD) is valued as a carbon-neutral energy source, while simultaneously treating organic waste, making it safer for disposal or use as a fertilizer on agricultural land. The AD process in many European nations, such as Germany, has grown from use of small, localized digesters to the operation of large-scale treatment facilities, which contribute significantly to national renewable energy quotas. However, these large AD plants are costly to run and demand intensive farming of energy crops for feedstock. Current policy in Germany has transitioned to support funding for smaller digesters, while also limiting the use of energy crops. AD within Ireland, as a new technology, is affected by ambiguous governmental policies concerning waste and energy. A clear governmental strategy supporting on-site AD processing of agricultural waste will significantly reduce Ireland's carbon footprint, improve the safety and bioavailability of agricultural waste, and provide an indigenous renewable energy source. © 2016 Society of Chemical Industry.

Use of K9 units in healthcare: a history

The use of K9 units within healthcare facilities will continue to increase as the violence within healthcare increases. K9s are a wise investment and are cost-effective. K9 units deter and prevent crime and violence at facilities. The typical K9 will be utilized for eight to ten years. The research demonstrates that facilities that have deployed K9 units have seen a reduction in crime and violence. A well trained K9 can not only patrol the exterior of a healthcare facility but also the patient care and service areas. As more hospitals and healthcare facilities look at non-lethal weapons to protect their officers, staff and guests, the use of K9 within healthcare will continue to rise.

Alice Magaw: a model for evidence-based practice

The model of evidence-based practice (EBP) of Alice Magaw places the practice of nurse anesthesia as an early pioneer in patient safety and is prophetic to the aims of the Institute of Medicine (IOM). In its 2001 report, Crossing the Quality Chasm, the IOM identified 6 aims essential to improving the delivery of care. These aims include safety, effectiveness, patient-centeredness, timeliness, efficiency, and equity. Magaw used her vast expertise in anesthetic administration to develop protocols and a body of knowledge that could be used as a template for practitioners near and far. This early use of EBP principles places nurse anesthesia at the forefront of the model and the movement to provide high-quality care. Practitioners sought her practice model out as she demonstrated her techniques to visiting providers as well as through her published ideal anesthetics in the literature. She wrote, "Pioneers are noted for building upon a body of knowledge, establishing a model for continuous improvement, and exemplifying notable methods of research with subsequent documentation of their findings." Magaw exemplified the EBP model.

Human milk banking to 1985

This paper provides a literature review of the use of donor human milk by hospitals in Australia and elsewhere from the postwar period through to the early 1980s, and establishes the context for a small study of practices which happened in that period. The latter study will be reported elsewhere. The purpose of this paper is to provide a resource for future comparison when the history of the new hospital milk banks of the 21st century is written. Relevant literature in English and two articles in French were accessed.

Communication of benefits and risks of medical radiation: a historical perspective

X-rays were discovered by Wilhelm Röntgen in 1895. Within one year, benefits of x-rays, such as visualization of fractures, and detriments, such as x-ray dermatitis, were recognized. Nobel Laureates Pierre and Marie Sklodowska Curie discovered the radioactive element radium in 1898, and a year later the application of radiation to cure cancer was reported. A significant price was paid for this: Marie Curie died of aplastic anemia related to her radiation exposure, and her daughter Irene Joliot Curie, Nobelist for radiochemical research, died of radiation-induced leukemia. Internationally developed radiation protection recommendations were formalized starting in the late 1920s. The increasing use of ionizing radiation in medical diagnosis and radiation therapy has brought significant societal benefits. Known risks of therapeutic radiation include coronary artery disease and secondary malignancy. However, recently concerns have been raised of possible very small but incremental increases in malignancies due to diagnostic medical radiation. Patients are largely unaware of, and referring physicians and even radiologists often underestimate, the carcinogenic effects of radiation. There is a need to determine the appropriateness of imaging tests that use ionizing radiation prior to performance; optimize imaging protocols to reduce unnecessary radiation; include patients in the decision process and encourage and enable them to track their radiation exposure; and promote education about medical radiation to patients, referring physicians, radiologists, and members of the public. The basic radiation protection principles of justification, optimization, and application of dose limits still pertain.

Addressing fear of crime in public space: gender differences in reaction to safety measures in train transit

Research has identified several factors that affect fear of crime in public space. However, the extent to which gender moderates the effectiveness of fear-reducing measures has received little attention. Using data from the Chicago Transit Authority Customer Satisfaction Survey of 2003, this study aims to understand whether train transit security practices and service attributes affect men and women differently. Findings indicate that, while the presence of video cameras has a lower effect on women's feelings of safety compared with men, frequent and on-time service matters more to male passengers. Additionally, experience with safety-related problems affects women significantly more than men. Conclusions discuss the implications of the study for theory and gender-specific policies to improve perceptions of transit safety.

Oil on the water: Government regulation of a carcinogen in the twentieth-century Lancashire cotton spinning industry

In the Lancashire cotton textile industry, mule spinners were prone to a chronic and sometimes fatal skin cancer (often affecting the groin). The disease had reached epidemic proportions by the 1920s, which necessitated action by the government, employers, and trade unions. In contrast to previous accounts, this article focuses on the government's reaction to mule spinners' cancer. Using official records in the National Archives, the slow introduction of health and safety measures by the government is explored in detail. Although obstructionism by the employers played a key role, one of the reasons for government inaction was the ambiguity of scientific research on engineering oils. On the other hand, prolonged scientific research suited a government policy that was framed around self regulation - a policy that had proved largely ineffective by the 1950s.

History and evolution of control banding: a review

Control banding (CB) strategies offer simplified solutions for controlling worker exposures to constituents often encountered in the workplace. The original CB model was developed within the pharmaceutical industry; however, the modern movement involves models developed for non-experts to input hazard and exposure potential information for bulk chemical processes, receiving control advice as a result. The CB approach utilizes these models for the dissemination of qualitative and semiquantitative risk assessment tools being developed to complement the traditional industrial hygiene model of air sampling and analysis. It is being applied and tested in small- and medium-sized enterprises within developed countries and industrially developing countries; however, large enterprises have also incorporated these strategies within chemical safety programs. Existing research of the components of the most available CB model, the Control of Substances Hazardous to Health Essentials, has shown that exposure bands do not always provide adequate margins of safety, that there is a high rate of under-control errors, that it works better with dusts than with vapors, that there is an inherent inaccuracy in estimating variability, and that when taken together the outcomes of this model may lead to potentially inappropriate workplace confidence in chemical exposure reduction in some operations. Alternatively, large-scale comparisons of industry exposure data to this CB model's outcomes have indicated more promising results with a high correlation seen internationally. With the accuracy of the toxicological ratings and hazard band classification currently in question, their proper re-evaluation will be of great benefit to the reliability of existing and future CB models. The need for a more complete analysis of CB model components and, most importantly, a more comprehensive prospective research process remains. This analysis will be important in understanding implications of the model's overall effectiveness. Since the CB approach is now being used worldwide with an even broader implementation in progress, further research toward understanding its strengths and weaknesses will assist in its further refinement and confidence in its ongoing utility.

Counting as caring

Perioperative nurses have developed specific expert nursing care practices. "Counting as caring" is certainly an approach in keeping with the perioperative nurse's guiding principle of beneficence (to do no harm). This article takes a retrospective look, from the first half of the last century through into the late 1960s, at the practice of counting and the influences that have changed it.

Fission, critical mass and safety--a historical review

Since the discovery of fission, the notion of a chain reaction in a critical mass releasing massive amounts of energy has haunted physicists. The possibility of a bomb or a reactor prompted much of the early work on determining a critical mass, but the need to avoid an accidental critical excursion during processing or transport of fissile material drove much that took place subsequently. Because of the variety of possible situations that might arise, it took some time to develop adequate theoretical tools for criticality safety and the early assessments were based on direct experiment. Some extension of these experiments to closely similar situations proved possible, but it was not until the 1960s that theoretical methods (and computers to run them) developed enough for them to become reliable assessment tools. Validating such theoretical methods remained a concern, but by the end of the century they formed the backbone of criticality safety assessment. This paper traces the evolution of these methods, principally in the UK and USA, and summarises some related work concerned with the nature of criticality accidents and their radiological consequences. It also indicates how the results have been communicated and used in ensuring nuclear safety.

From strange bedfellows to natural allies: the shifting allegiance of fire service organisations in the push for federal fire-safe cigarette legislation

BACKGROUND

Cigarettes are the leading cause of fatal fires in the USA and are associated with one in four fire deaths. Although the technology needed to make fire-safe cigarettes has been available for many years, progress has been slow on legislative and regulatory fronts to require the tobacco industry to manufacture fire-safe cigarettes.

METHOD AND RESULTS

We conducted a case study, drawing on data from tobacco industry documents, archives, and key informant interviews to investigate tobacco industry strategies for thwarting fire-safe cigarette legislation in the US Congress. We apply a theoretical framework that posits that policymaking is the product of three sets of forces: interests, institutions, and ideas, to examine tobacco industry behaviour, with a special focus on their and others' attempts to court fire service organisations, including firefighters' unions as allies. We discuss the implications of our findings for future policy efforts related to fire-safe cigarettes and other tobacco control issues.

CONCLUSIONS

Tobacco control advocates ought to: continue efforts to align key interest groups, including the firefighters unions; contest tobacco industry "diversionary" science tactics; and pursue a state based legislative strategy for fire-safe cigarettes, building towards national legislation.

[The dilatation of auditive tube (Bougirage tubaire) by dilators in XIX century]

The treatment of auditiory tube chronic catarrh in XIX century by pharmagological drugs, by special apparatuses of surprising technical sophistication, by electrisation and faradisation is discussed first of all. The dilatation of auditory tube by dilators was the diagnostical and therapeutical methods, especially preferenced by Victor Urbantschitsch, Hermann Schwartze, Jean P. Bonnafonte, Albert Calmettes and Bronisław Taczanowski, Teodor Heiman and Samuel Meyerson. The dilators were building of celluloid, whale-bone, silver and were absorbed by argentum nitrate, vaseline. The technique, difficulties and effects of dilatation are described in more detail. The complications of this operation is presented finally.

A review of the history of U.S. radiation protection regulations, recommendations, and standards

Shortly after the discovery of x rays by Wilhelm Konrad Roentgen in 1895, and the isolation of the element radium by Pierre and Marie Curie three years later, the fascination with and potential for an array of uses of ionizing radiation in medicine, science, and technology was born. As with any new technology, there was a need to balance both the beneficial and potential detrimental effects of uses of these new technologies for the advancement of humankind. In the early days, radiation hazards were not well understood. Over the decades increasing concerns in the scientific community and lay population demanded that standardized guidance and recommendations be developed for the use of ionizing radiation. Today, U.S. radiation protection standards and recommendations to protect the occupational worker, members of the general public, and the environment are numerous and complex. This review summarizes the history of the development and application of radiation protection standards and regulations to assure the safe use of radiation and radioactive materials. The evolution and roles of international and national scientific recommending and regulatory organizations that shape U.S. radiation protection policy are described and discussed.

The Health Physics Society: a 50-year chronology

In 2005, the Health Physics Society celebrates its 50th anniversary. During its half century of existence, the Society has evolved from a small group of operationally oriented radiation protection scientists into an organization of several thousand with a recognized and respected peer reviewed journal. The bold decision to form an organization devoted to radiation safety in the United States spurred the formation of such societies in other countries and led to the formation of an international confederation of national societies, which has facilitated scientific communication and exchange worldwide. It also led to the formation of a separate body for the certification of health physicists, which in turn has grown into an academy with more than 1,000 members, and was instrumental in providing basic information establishing the need for a registry of radiation protection technologists.

John M. Eisenberg Patient Safety Awards. Individual lifetime achievement: Julianne M. Morath, RN, MS

BACKGROUND

This article provides a brief biography of Julianne M. Morath, describes the scope and impact of her patient safety initiatives at Children's Hospitals and Clinics in Minneapolis and St Paul, and includes an interview in which Morath responds to questions about challenges to patient safety and medical accident reduction.

BIOGRAPHY IN BRIEF

With a 25-year career spanning the spectrum of health care, Morath has served in leadership positions in health care organizations in Minnesota, Rhode Island, Ohio, and Georgia.

LEADERSHIP AT THE FRONT LINE

Morath joined Children's Hospitals and Clinics in 1999 and launched a major patient safety initiative that put Children's on the map. Elements of the initiative included a culture of learning, patient safety action teams, open discussion of medical accidents and error, blameless reporting, and a full accident disclosure policy.

AN INTERVIEW WITH JULIE MORATH

As the greatest challenge to leadership ownership of the patient safety initiative, Morath cites the need to confront the myths of the medical system and to develop the awareness of the issues of patient safety. She believes that clinicians on the front lines will be convinced that patient safety isn't "just another fad of the month" when leadership action is disciplined and aligns with what is being espoused. She advises other leaders of health care organizations interested in establishing a culture of safety to start with a personal and passionate belief that harm-free care is possible, to commit to informed action, and to identify and develop champions throughout the organization and medical staff.

Historical analysis of siderail use in American hospitals

PURPOSE

To explore the social, economic, and legal influences on siderail use in 20th century American hospitals and how use of siderails became embedded in nursing practice.

DESIGN

Social historical research.

METHODS

Numerous primary and secondary sources were collected and interpreted to illustrate the pattern of siderail use, the value attached to siderails, and attitudes about using siderails.

FINDINGS

The persistent use of siderails in American hospitals indicates a gradual consensus between law and medicine rather than an empirically driven nursing intervention. Use of siderails became embedded in nursing practice as nurses assumed increasing responsibility for their actions as institutional employees.

CONCLUSIONS

New federal guidelines, based on reports of adverse consequences associated with siderails, are limiting siderail use in hospitals and nursing homes across the United States. Lowering siderails and using alternatives will depend on new norms among health care providers, hospital administrators, bed manufacturers, insurers, attorneys, regulators, and patients and their families.

Safe biotechnology. 7. Classification of microorganisms on the basis of hazard. Working Party "Safety in Biotechnology" of the European Federation Biotechnology

The current systems for classifying human pathogens on the basis of hazard are well developed and their basic criteria are in general agreement one with another. Of more importance, the safety practices based on these classifications have generally been successful. They have enabled extensive research activities, medical practice and industrial production to be conducted on an ever-increasing scale, involving dangerous microorganisms (e.g. in vaccine production and treatment of infected patients) with a very low incidence of adverse effects on the workers involved and the general public. Although the EU has adopted a harmonised list of agents in groups 1-4 there is as yet no complete agreement among member states and individual microbiologists. The purpose of this paper is to present a historical survey and to discuss the current processes for identifying and classifying the hazards posed by the use of microorganisms in research and technology. This is essential in the design of appropriate methods of counteracting potential risks.
