“…This study used a hierarchical process described by Dajani et al, 25 that included participant consensus (the percentage of participants agreeing on a particular response), followed by stability of opinion in the absence of consensus (consistency of answers between successive rounds of the questionnaire without achieving the pre-defined criteria for consensus), which is consistent with other Delphi studies. [13][14][15]25,26 The demonstration of convergence, (which is a progressive decrease in range and standard deviation of responses as rounds progressed 27 ), suggested increased panelist agreement, and further supported the study conclusions. The anonymous nature of the process avoided the influence of strong personalities and other group dynamics.…”

“…As there is significant disagreement in the literature regarding consensus and stability, these values were determined a priori and based on values used in similar studies. [13][14][15][16] Once an item achieved consensus or stability, it was removed from further rounds of the Delphi process. The process was conducted in a "quasi-anonymous" manner.…”

Objective: There is no evidence-based description of electrocardiogram (ECG) interpretation competencies for emergency medicine (EM) trainees. The first step in defining these competencies is to develop a prioritized list of adult ECG findings relevant to EM contexts. The purpose of this study was to categorize the importance of various adult ECG diagnoses and/or findings for the EM trainee. Methods: We developed a list of potentially important adult ECG diagnoses/findings and conducted a Delphi opinionsoliciting process. Participants used a 4-point Likert scale to rate the importance of each diagnosis for EM trainees. Consensus was defined as a minimum of 75% agreement at the second round or later. In the absence of consensus, stability was defined as a shift of 20% or less after successive rounds. Results: A purposive sampling of 22 emergency physicians participated in the Delphi process, and 16 (72%) completed the process. Of those, 15 were from 11 different EM training programs across Canada and one was an expert in EM electrocardiography. Overall, 78 diagnoses reached consensus, 42 achieved stability and one diagnosis achieved neither consensus nor stability. Out of 121 potentially important adult ECG diagnoses, 53 (44%) were considered "must know" diagnoses, 61 (50%) "should know" diagnoses, and 7 (6%) "nice to know" diagnoses. Conclusion: We have categorized adult ECG diagnoses within an EM training context, knowledge of which may allow clinical EM teachers to establish educational priorities. This categorization will also facilitate the development of an educational framework to establish EM trainee competency in ECG interpretation. RÉSUMÉObjectif: Il n'existe aucune description, fondée sur des données probantes, de la compétence que doivent acquérir les stagiaires en médecine d'urgence (MU) dans l'interprétation de l'électrocardiogramme (ECG). La première étape pour définir cette compétence consiste en l'élaboration d'une liste prioritaire de signes électrocardiographiques chez l'adulte, pertinents en MU. L'étude décrite ici avait pour but de classer l'importance de divers signes électrocardiographiques et diagnostics fondés sur l'ECG chez l'adulte, à l'intention des stagiaires en MU. Méthode: Les auteurs ont dressé une liste de signes électrocardiographiques et de diagnostics fondés sur l'ECG chez l'adulte, potentiellement importants à connaître par les stagiaires, et ont mené une enquête d'opinion selon la méthode Delphi. Les participants ont coté l'importance de chaque diagnostic pour les stagiaires en MU, sur une échelle de Likert à 4 points. Le consensus a été défini comme un taux minimal de convergence de 75 % au second tour ou à un tour ultérieur. En l'absence de consensus, la stabilité a été définie comme un changement d'opinion égal ou inférieur à 20 % après les différents tours. Résultats: Un échantillon choisi à dessein et composé de 22 médecins d'urgence a participé à l'enquête menée selon la méthode Delphi, et 16 répondants (72 %) se sont rendus à la fin du processus. Sur ce dernier...

“…The linguistic variables are then converted into triangular fuzzy numbers as suggested in Tables 1 and 2 According to Cheng and Lin [18], if the distance between the average and the expert's evaluation data is less than the threshold value of 0.2, then all the experts are considered to have achieved a consensus. Furthermore, among the n m× ratings of alternatives and n criteria weights, if the percentage of achieving a consensus is greater than 75% [19,20], then we calculate the fuzzy evaluation of each alternative. Otherwise, a second survey round is required.…”

Abstract-The objective of this study is to develop an assessment model that can be used to evaluate hydrogen fuel cell applications and provide a screening tool for decision makers. This model operates by selecting the evaluation indicators, determining criteria weight, and assessing the performance of hydrogen fuel cell applications with respect to each criterion. The fuzzy Delphi method (FDM) was used to select the criteria and the preferred hydrogen fuel cell products based on the information collected from a group of experts. Survey questionnaires were sent out to obtain the opinions of experts in different fields. After two rounds of surveying, the group consensus, criteria weight, and ranking of options were obtained. The selected criteria included four general fields-environment, technology, economy, and society, 14 indicators such as energy efficiency and CO 2 emission, and seven hydrogen fuel cell applications such as fuel cell forklifts and fuel cell backup power systems. The results show that the fuel cell backup power system ranked the highest, followed by household fuel cell electric-heat composite systems. The criteria provide a screening tool for decision makers to select appropriate hydrogen-related applications.

“…The Delphi method was applied to define the evaluation criteria and sub-criteria. Murry and Hammons suggested that the Delphi method should summaries expert opinions on a range from 10 to 30 [8]. Therefore, an initial questionnaire was distributed to 11 experts.…”

Abstract. While industry-oriented applications have been extensively investigated, the mold combination 3D printing product creativity for vocational college students is unexplored. First, this study collects the status of mold technology and 3D printing in various countries, the scope of technical knowledge of molds and the relevant literature on creativity performance. In addition, this study involves a quantitative and qualitative content analysis of relevant documents, textbooks and educational objectives of mold performance creativity, which includes mold technology, 3D printing design and production, industry-oriented applications in three hierarchies and 21 indexes. Second, this study assesses these criteria by employing the analytic hierarchy process (AHP) technique to solicit opinions from 11 experts by using questionnaires. Results show that mold technology, 3D printing design and production, industry-oriented applications have weights of 34%, 32.4%, 33.6%, respectively.
