This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and...
Despite the efforts of health care practitioners, medical errors are inevitable. Disclosure of errors is patients’ demand and right. The aim of this study was to determine the nursing staff’s attitudes about disclosure of medical errors to patients and its relationship with disclosure of actual and hypothetical errors. In this descriptive cross-sectional study, 180 of the nursing staff employed...
Current dosimetry protocols require geometrical reference conditions for the determination of absorbed dose in external radiotherapy. Whenever these geometrical conditions cannot be maintained the application of additional corrections becomes necessary, in principle. The current DIN6800-2 protocol includes a corresponding factor k(NR), but numerical values are lacking and no definite informatio...
Reasoning with hypothetical cases helps decision-makers evaluate alternate hypotheses for deciding a case. The hypotheticals demonstrate the sensitivity of a hypothesis to apparently small factual differences that may require different results because they shift the tradeoffs among conflicting underlying principles. By anticipating variations, the decision-maker seeks to formulate as general an...
