The FDA established the Standardized Data Collection for Cardiovascular Trials Initiative in 2009 to simplify the design and conduct of clinical trials intended to support marketing applications. The writing committee recognizes that these definitions may be used in other types of clinical trials and clinical care processes where appropriate. Use of these definitions at the FDA has enhanced the ability to aggregate data within and across medical product development programs, conduct meta-analyses to evaluate cardiovascular safety, integrate data from multiple trials, and compare effectiveness of drugs and devices. Further study is needed to determine whether prospective data collection using these common definitions improves the design, conduct, and interpretability of the results of clinical trials.

A review of research on innovation and new product development points to certain foundational issues of concern such as the use of (1) different definitions of constructs germane to the field (e.g., ...definitions of innovation, innovativeness, and specific types of innovations), (2) different construct labels to refer to specific innovation types, and (3) the same construct label to refer to different innovation types. Over the years, scholars have cautioned that a body of research in a field of study that is based on different definitions of constructs germane to the field would slow the advancement of knowledge. Against this backdrop, the purpose of this Catalyst paper is to initiate a conversation on the prospects for mitigating the definitional quagmire in research on innovation and new product development by developing an inclusive definition of innovation that can be used as a template for defining various types of innovations uniformly. Toward this end, the paper proposes an inclusive definition of innovation based on idea, outcome, and value creation as the defining or essential characteristics of all innovations. Definitions of 10 specific types of innovations defined in a consistent manner, employing the proposed inclusive definition of innovation as a template are also presented. All else being equal, consistency across research studies in the definitions of constructs employed can be conducive to the advancement of knowledge in a field of study in several ways such as streamlining the curation of the research‐based knowledge, facilitating the grounding of new research in prior research (i.e., curated knowledge), and eliminating differences across studies in the definitions of key constructs employed as a potential confound on the research findings.
The term represents an integral element of each subject and forms the basis for the development of knowledge and mastery of knowledge acquired through the development of science. The school and the ...course book should enable students to adopt a system of scientific concepts from a certain field. This work deals with the analysis of the concepts of nature in the coursebooks of Nature and Society for the fourth grade of primary school, published by the publishers: Klett, New logos, and Bigz schooling. The research provides answers to the following questions: Are the concepts of nature explicitly represented in coursebooks? Do complete and incomplete logical definitions of the concepts of nature dominate in the coursebooks of Nature and Society? Is there a dominance of complete and incomplete logical definitions of different publishers and by the dominance of complete and incomplete logical definitions of the concepts of nature? Based on the results of research on the definitions of the concepts of nature in the coursebooks of Nature and Society for the fourth grade, it can be concluded that the coursebooks of Klett, New logos, and Bigz schooling have a very large number of undefined concepts of nature, greater than the number of definitions. Most textbooks about nature are in the textbook published by Klett (198 terms), followed by the textbook published by New Logos (174 terms), while the least notions about nature are found in the textbook published by Bigz schooling (142 terms). The most accurate definitions are in the textbook published by Klett (86 definitions), followed by the textbook published by New Logos (83 definitions), while the least definitions of nature are found in the textbook Bigz schooling (59 definitions). All of this points to the need for detailed changes to the analyzed nature and society textbooks from the publishing houses Klett, New logos, and Bigz schooling. This problem will certainly be the subject of academic discussion and some future research.

‘Crowdsourcing’ is a relatively recent concept that encompasses many practices. This diversity leads to the blurring of the limits of crowdsourcing that may be identified virtually with any type of ...internet-based collaborative activity, such as co-creation or user innovation. Varying definitions of crowdsourcing exist, and therefore some authors present certain specific examples of crowdsourcing as paradigmatic, while others present the same examples as the opposite. In this article, existing definitions of crowdsourcing are analysed to extract common elements and to establish the basic characteristics of any crowdsourcing initiative. Based on these existing definitions, an exhaustive and consistent definition for crowdsourcing is presented and contrasted in 11 cases.
The current study is part of a comprehensive research on linking visualization, students’ construction of geometrical concepts and their definitions, and students’ ability to prove. The aim of the ...current study is to investigate the effect of learners’ understanding of definitions of geometrical concepts on their understanding of the essence of geometrical proofs and their ways of proving. By “understanding” (geometrical definitions and/or proofs), we mean knowing the definition’s and/or proof’s meaning and their role within the logic structure of geometry and also the ability to define and/or prove in “geometrically correct” ways. Ninety grade 11 students from an Arab high school in Israel participated in the comprehensive study in geometry of which the current study forms a part. Research tasks for the investigation of the current study’s aim were designed, constructed, and used in a questionnaire to the whole research population and in interviews with about 10% of the population. The findings point clearly to effects of elements within the students’ understanding of definitions on their understanding of proofs and on their ability to prove. These elements are as follows: (a) The difficulty to internalize that an incomplete definition is an incorrect definition and may lead to an incomplete proof. (b) The difficulty to deal with non-economical definitions forms the basis to non-economical proofs. (c) Students have difficulties to accept equivalent definitions to the same geometrical concept. (d) The students’ lack of understanding the origin of a constructive definition of geometrical concept.

The empathy concept has central significance for social and personality psychology and in many other domains, including neuroscience, clinical/abnormal psychology, and the health professions. ...However, the current diversity in conceptual and operational definitions, and the promiscuous use of the term "empathy," threaten the ability of researchers to advance the field. The present article provides a quantitative review and conceptual analysis of empathy definitions and usages by examining 393 studies published between 2001 and 2013, and 96 studies published in 2017. We document the prevalence and diversity of definitions, as well as inconsistencies between conceptual definitions and measurements employed. We discuss ways to refine the conceptualization and operationalization of the empathy construct, including for many purposes, bypassing the term empathy in favor of lower-level construct labels that more precisely describe what is actually being measured. In many cases we see no added theoretical or empirical value in applying the term empathy.

Central line...associated bloodstream infection (CLABSI) is the current benchmark used in HAI (Hospital-associated infection) surveillance and effective interventions have greatly reduced the ...incidence in recent years. However, bloodstream infection (BSI) continues to be a major source of morbidity and mortality in hospitals. Hospital-onset bloodstream infection (HOBSI), which includes central and peripheral line surveillance, may be a more sensitive indicator of preventable BSI. Our objective is to assess the impact of a change to HOBSI surveillance by comparing the incidence of BSIs using the National Health care and Safety Network LabID and BSI definitions compared to CLABSI.
Utilizing electronic medical charts, we determined if each blood culture met the HOBSI criteria according to the National Health care and Safety Network LabID and BSI definitions. We calculated the incidence rates (IRs) per 10,000 patient days for both definitions and compared them to the CLABSI rate per 10,000 patient days for the same period.
The IR of HOBSI using the LabID definition was 10.25. Using the BSI definition, we found an IR of 3.77. The IR of CLABSI for the same period was 1.84.
After excluding secondary BSIs, the HOBSI rate is still double that of the CLABSI rate. HOBSI surveillance is a more sensitive indicator of BSI than CLABSI, and thus a better target for monitoring effectiveness of interventions.
