Making decisions about hazardous waste remediation when even considering a remediation technology is controversial.

This paper investigates the circumstances under which proposed hazardous waste remediation technologies are socially acceptable, that is, considered seriously as options in a public arena. First, it summarizes a conceptual framework that guides investigation and interpretation of site-specific remediation decision-making. Second, it describes an initial application of that framework to the public participation venue of U.S. DOE Site-Specific Advisory Boards. Investigating the attributes of involved parties and of site context highlights technology acceptability as social decision-making that involves technical and technological issues rather than as a process driven by the technology itself.

Older adults' motivated choice for technological innovation: evidence for benefit-driven selectivity.

This study examined older adults' motivation to adopt technological innovation. Sixty-eight older e-mail users and nonusers discussed the use of e-mail and of traditional communication methods in 18 focus groups. The results show older adults' benefit-driven approach to new communication technology. Regardless of whether their decision about the new technology was positive or negative and irrespective of their e-mail experience, participants focused on benefits rather than costs. For traditional media, both costs and benefits were important. Results contradict the common belief that barriers such as usability problems determine whether older people use new technology and indicate the decisive role of perceived benefits for successful innovation.

Nursing in the dialysis unit: technological enframing and a declining art, or an imperative for caring.

Nursing in haemodialysis units has been well established since the 1960s. Technological developments, open patient selection methods and economic pressures have altered the dialysis unit to become increasingly busy, where demand outstrips availability. For nurses it has become akin to working on a 'production-line' in order to meet the need for treatment. The increasing demand has required the nurse to become technologically skilled often to the detriment of caring. What emerges is the nurse enframed by technology where the caring of nurses is focused through the demand of getting the patients processed. Here is a dilemma where caring becomes a moral imperative in order to overcome the dehumanising effects of technology, and the future of the dialysis nurse comes into question.

Utilization of technologies to reduce allogeneic blood transfusion in the United States.

Concern over safety of the blood supply has led to the use of technologies to reduce allogeneic blood transfusion. The objective of this research was to determine the utilization of these technologies in the United States. We evaluated the following techniques: preoperative autologous donation (PAD), cell salvage (CS) and acute normovolemic haemodilution (ANH); and the following pharmaceuticals: aprotinin (APR), epsilon-aminocaproic acid (EACA), tranexamic acid (TXA), desmopressin (DDAVP) and recombinant human erythropoietin (EPO). In 1997, we conducted a cross-sectional mail survey of service chiefs at 1000 US hospitals randomly selected and stratified by status as a provider of open-heart surgery, geographical location and hospital bed size. Sixty-nine per cent (690) of hospitals responded to at least one of the four surveys sent to each hospital. Hospitals reported use of techniques more than pharmaceuticals (P < 0.001); PAD (83%, n = 206) and CS (82% n = 420) were used most frequently. Lack of familiarity was the most common reason cited for infrequent use of pharmaceuticals. Organizational characteristics (e.g. provision of open-heart surgery, size, geographical location, teaching status and type of hospital) were differentially associated with technology use. There is greater use of techniques than pharmaceuticals in US hospitals to reduce the need for allogeneic blood in the peri-operative setting. Providing open-heart surgery is strongly associated with the utilization of these technologies.

Quality assurance and technology assessment: pieces of a larger puzzle.

Increasing integration of health care and health services research has resulted in an overlap between disciplines involved in the evaluation of clinical practice. We have examined the relationships of quality assurance (QA), medical technology assessment (TA), clinical epidemiology (CE) and evidence-based medicine (EBM) from an historical perspective. Clinicians, patients and administrators need local information on effectiveness of routine care. Information from trials alone, efficacy data, will not suffice nor can it be culled from administrative databases designed for other purposes. The current activities of QA should be therefore be expanded to include the study of the effectiveness of interventions in terms of appropriateness of use, patient outcomes and study of the determinants of outcomes, as seen from the perspective of doctors, patients, administrators and policy makers, using data collected during the course of routine patient care. With the assistance of information technology, with methodological support and multidisciplinary cooperation, clinicians can do this as part of a more broadly defined clinical research. Quality assurance and TA both evolved with the objective of studying clinical care but have quite different historical roots, complementary perspectives and objectives, use different methods and involve a different set of practitioners. Quality assurance is a type of 'formative' evaluation conducted in the clinical setting using indicators as flags of process or outcome events of interest, simple surveys and audit studies. Its primary aim is to achieve incremental improvement rather than to simply pass judgement. An important underlying assumption is that health care behaves as a complex dynamic system. Technology assessment, a form of summative evaluation with an orientation towards policy, synthesises information from formal scientific studies of efficacy in the form of clinical trials and studies of cost-effectiveness. For the evaluation of the impact of any technology more complex than a drug, the complementary contributions of both of these disciplines is needed, and QA and TA should work cooperatively in tandem with the support of CE and EBM.

Understanding technology in contemporary surgical nursing: a phenomenographic examination.

The purpose of this paper is to describe the result of phenomenographic research undertaken to identify the qualitatively different ways technology is understood and experienced by contemporary surgical nurses. Twenty surgical nurses were interviewed and conversations were recorded through the use of drawings and audiotape that were analysed using a series of seven analytical steps. There were two major outcomes of the research: eight categories of description were revealed and each one constitutes a conception of the experience and understanding of technology, and an outcome space portraying the logical relations between conceptions was identified. Conceptions revealed demonstrate the importance of technology to the theory, practice, research and education of nurses, and highlight the complexity and significance of technology in contemporary surgical nursing experience.

Comparative risk analysis of technological hazards (a review).

Hazards are threats to people and what they value and risks are measures of hazards. Comparative analyses of the risks and hazards of technology can be dated to Starr's 1969 paper [Starr, C. (1969) Science 165, 1232-1238] but are rooted in recent trends in the evolution of technology, the identification of hazard, the perception of risk, and the activities of society. These trends have spawned an interdisciplinary quasi profession with new terminology, methodology, and literature. A review of 54 English-language monographs and book-length collections, published between 1970 and 1983, identified seven recurring themes: (i) overviews of the field of risk assessment, (ii) efforts to estimate and quantify risk, (iii) discussions of risk acceptability, (iv) perception, (v) analyses of regulation, (vi) case studies of specific technological hazards, and (vii) agenda for research. Within this field, science occupies a unique niche, for many technological hazards transcend the realm of ordinary experience and require expert study. Scientists can make unique contributions to each area of hazard management but their primary contribution is the practice of basic science. Beyond that, science needs to further risk assessment by understanding the more subtle processes of hazard creation and by establishing conventions for estimating risk and for presenting and handling uncertainty. Scientists can enlighten the discussion of tolerable risk by setting risks into comparative contexts, by studying the process of evaluation, and by participating as knowledgeable individuals, but they cannot decide the issue. Science can inform the hazard management process by broadening the range of alternative control actions and modes of implementation and by devising methods to evaluate their effectiveness.

Comparative evaluation of molecular technologies for the identification of prevalent non-tuberculous mycobacteria in pulmonary infections: a systematic review and meta-analysis.

BACKGROUND: The increasing prevalence of non-tuberculous mycobacteria pulmonary disease (NTM PD) is a burden to public health. Successful management of NTM PD critically depends on accurate species identification and reliable drug susceptibility testing to guide appropriate antibiotic therapy. Emerging molecular technologies offer rapid diagnostic solutions compared to conventional methods, but their performance varies. This study aims to provide a comprehensive evaluation of current molecular techniques for NTM identification and to present a global antibiotic resistance profile. METHODS: A systematic literature search was conducted in PubMed and Web of Science for studies published between 2005 and 2024. Studies applying molecular methods for NTM identification and resistance detection in humans were included. Data on study characteristics, diagnostic methods, sample types, sample sizes, identification sensitivity, and drug susceptibility results were extracted. Meta-analysis was performed using R with the meta4diag package. The quality of included studies was assessed using the QUADAS-2 tool. RESULTS: The analysis included 49 studies on NTM identification and 33 studies on antibiotic resistance. For species identification, all evaluated molecular technologies (MALDI-TOF MS, PCR-based methods, Sequencing, DNA chip, and DNA strip) demonstrated high pooled sensitivities (>0.92). Subgroup analysis revealed that sample type significantly affected performance for MALDI-TOF MS. Preliminary analysis of antibiotic resistance rates revealed varying patterns. For slowly growing mycobacteria, a significantly high Ethambutol resistance rate was observed in M. avium (69.20%). Among rapidly growing mycobacteria, resistance to Imipenem was notable (54.22%), and Clarithromycin resistance varied significantly within the Mycobacterium abscessus complex. CONCLUSION: Emerging molecular technologies have revolutionized the methodology for NTM identification with excellent performance. However, their performance can be influenced by sample type, particularly for MALDI-TOF MS. The alarming and heterogeneous antibiotic resistance patterns also highlight the critical need for rapid and accurate species identification and drug susceptibility testing to inform effective therapeutic strategies. Key messagesMolecular technologies demonstrate high accuracy for NTM identification.Antibiotic resistance is a serious concern with variations among NTM species and subspecies.Rapid and accurate species identification and drug susceptibility testing are crucial for guiding effective clinical management of NTM PD.

Selection of rural assistive technology using a HyperCard-based knowledge system.

Resources and expertise on selecting assistive technology appropriate for an agricultural work setting are scarce. To meet this need a prototype knowledge system for the selection and documentation of rural assistive technology (BNG DATA) was developed to aid professionals working with farmers, ranchers, and agricultural workers with physical disabilities. The knowledge system consists of a hypertext database of technology examples and a decision support system that helps users identify solution alternatives to meet consumers' needs. End-user acceptance of BNG DATA was determined through field trials and an evaluation questionnaire administered to staff of the U.S. Department of Agriculture's AgrAbility Project. Using a statistical experiment in conjunction with the questionnaire, it was concluded that BNG DATA significantly reduced the time required by end users to find acceptable solution alternatives for consumers and increased the end users' confidence in the solutions they obtained. This manuscript describes the development and testing of BNG DATA, focusing on the selection of appropriate technology.

Frequency measures of behavior for assistive technology and rehabilitation.

Documenting assistive technology outcomes has grown in importance, but outcome measurement remains problematic. A new approach uses natural science measures and a model (selectionism) from the field of Behavior Analysis. Selectionism defines behaviors by their effects (functional performance) and the environment (including technology) within which they occur, and explicitly treats variation in patterns of behavior over time for individuals (intervention effects). Its basic metric is frequency of behaviors (count per unit time) which is similar to robust engineering measures like centimeters, grams, and seconds. This approach eliminates many of the problems inherent to more traditional psychometrics. Selectionism based on frequencies also provides an empirical structure or taxonomy to organize efforts and outcomes, unified by the notion of fluency. Composite behaviors are combinations of smaller component behaviors that are required for performance of the composite. A frequency above which a component behavior is readily retained, generalized, and recruited into the more complex composite behavior is called fluency; thus individuals fluent on the critical components easily and efficiently demonstrate the composite. This model suggests that when assistive technology interventions raise component behavior frequencies to fluent levels, they will be integrated usefully into an individual's life. This selectionistic approach has been used successfully in the field of education. It has the added benefit of not only empirically defining measurable outcomes, but also of providing useful ongoing measurement of change during treatment. This paper briefly describes this "Precision Measurement" strategy and its data-driven feedback process and makes suggestions for further research and development efforts. The method provides a basis for better documentation, control, and outcomes of assistive technology and related interventions.

A review of conceptual models for assistive technology outcomes research and practice.

Conceptual models provide a theoretical basis for advancing scientific knowledge and improving professional practice. Although numerous assistive technology-related models have appeared in the literature, there has been no systematic effort to assess them. Six conceptual models are reviewed here: Cook and Hussey's Human-Activity-Assistive Technology model; the World Health Organization's International Classification of Functioning, Disability, and Health; Scherer's Matching Person and Technology model; Gitlin's model of an AT user's "career"; social cognition decision-making theories; and Rogers' Perceived Attributes Theory. The models are reviewed in terms of six domains: background and goals; descriptive characteristics; indication of outcome measures; predictive characteristics; validation in the literature; and utility to assistive technology practitioners, developers, and consumers. The salient strengths and limitations are highlighted for each. Application of the models to advance theory, research, and practice is discussed.

Accomplishing technology transfer: case-based lessons of what works and what does not.

This paper presents lessons drawn from technology transfer case studies that address the persistent question: "What works, what does not, and why?" Each lesson highlights critical factors determining success or failure and is substantiated by case studies that exemplify the lesson. The case examples involve either the commercialization of prototype inventions (supply-push technology transfer) or the acquisition of desired technologies from other fields of application (demand-pull technology transfer). The cases present the chronology of events as they actually occurred, including supporting information from the other participants. Applying the lessons should help avoid common mistakes while increasing the likelihood of accomplishing the desired outcomes.

Controlling air pollution from passenger ferries: cost-effectiveness of seven technological options.

Continued interest in improving air quality in the United States along with renewed interest in the expansion of urban passenger ferry service has created concern about air pollution from ferry vessels. This paper presents a methodology for estimating the air pollution emissions from passenger ferries and the costs of emissions control strategies. The methodology is used to estimate the emissions and costs of retrofitting or re-powering ferries with seven technological options (combinations of propulsion and emission control systems) onto three vessels currently in service in San Francisco Bay. The technologies include improved engine design, cleaner fuels (including natural gas), and exhaust gas cleanup devices. The three vessels span a range of ages and technologies, from a 25-year-old monohull to a modern, high-speed catamaran built only four years ago. By looking at a range of technologies, vessel designs, and service conditions, a sense of the broader implications of controlling emissions from passenger ferries across a range of vessels and service profiles is provided. Tier 2-certified engines are the most cost-effective choice, but all options are cost-effective relative to other emission control strategies already in place in the transportation system.
