Cancer stem cell definitions and terminology:the devil is in the details
2012
The cancer stem cell (CSC) concept has important therapeutic implications, but its investigation has been hampered both by a lack of consistency in the terms used for these cells and by how they are defined. Evidence of their heterogeneous origins, frequencies and their genomic, as well as their phenotypic and functional, properties has added to the confusion and has fuelled new ideas and controversies. Participants in The Year 2011 Working Conference on CSCs met to review these issues and to propose a conceptual and practical framework for CSC terminology. More precise reporting of the parameters that are used to identify CSCs and to attribute responses to them is also recommended as key t…
Measurement of Simplified Single- And Three-Phase Parameters for Harmonic Emission Assessment Based on IEEE 1459-2010
2021
This article investigates the feasibility of using a simplified approach, based on the measurement of power ratio parameters, for harmonic emissions assessment at the point of common coupling (PCC). The proposed approach comes from the common concept of power factor correction and the definitions of the IEEE Std. 1459-2010, where line utilization and harmonic pollution levels are evaluated by means of ratios between the power quantities of the apparent power decomposition. In addition to the IEEE Std. 1459–2010 indicators, in this article, the behavior is studied of additional parameters that are conceptually similar to those defined by the IEEE Std. 1459-2010. The suitability of such param…
Cryptocurrencies in the Light of Money Definitions
2020
Purpose: The aim of the article is to attempt to assess the phenomenon of digital currencies through the prism of existing money definitions as well as to determine to what extent the existing definitions of money are able to answer the question whether private decentralized digital currencies are money in the traditional sense or are they a completely new phenomenon that cannot be put in the framework of previous definitions of money. Design/methodology/approach: This study provides a critical literature review of the cryptocurrency’s definitions in comparison to traditional money definition. The literature review was intended to determine whether bitcoin could be treated as money. Finding…
Definitions and measurement of health literacy in health and medicine research: a systematic review
2022
ObjectivesThe way health literacy is understood (conceptualised) should be closely linked to how it is measured (operationalised). This study aimed to gain insights into how health literacy is defined and measured in current health literacy research and to examine the relationship between health literacy definitions and instruments.DesignSystematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.Data sourcesThe MEDLINE, PsycINFO, ERIC and CINAHL databases were searched for articles published during two randomly selected months (March and October) in 2019.Eligibility criteriaWe included articles with a quantitative design that measur…
A New Measurement Method for the Detection of Harmonic Sources in Power Systems Based on the Approach of the IEEE Std. 1459–2000
2010
In this paper, a novel single-point strategy is proposed for the detection of the harmonic sources in power systems. The method is an improvement of a strategy previously proposed by the authors; it is developed from the IEEE Std 1459-2000 approach and it can be entirely implemented in the time domain, thus simplifying the measurement system. The effectiveness of the proposed method is evaluated by introducing simple decision-making rules and by taking the presence of the measurement transducers into account. Several simulations and experimental tests are presented, showing that the enhanced strategy is able to give an useful information on the detection of the dominant harmonic source upst…
The Global Grounding System: Definitions and guidelines
2015
The present paper presents the preliminary results of the ongoing Italian METERGLOB project on the contribution given by the exposed conductive parts to a Global Grounding System. One of the expected results of METERGLOB is to carry out guidelines for the identification of a Global Grounding System. These guidelines must be defined on the basis of the definitions and methods present in the current international standards on grounding and safety. In the paper some definitions and elements to be taken into account for the identification of a Global Grounding System are given.

Explaining Hooke’s Law : Definitional Practices in a CLIL Physics Classroom
2016
This article examines how a teacher in a Content-and-Language-Integrated-Learning (CLIL) program engages in various definitional practices during a plenary episode in a physics class taught in English in Finland. The episode focuses on explaining Hooke’s law, which involves defining its key concepts and their relations as instructable matters. Using multimodal conversation analysis, the article shows how the teacher accomplishes definitions and definition-related actions through talk and a range of embodied and material resources. The different configurations of resources are coordinated to elucidate the key concepts, to contextualize them in relation to the larger activity, and to situate …

2015
International audience; Background: Studies carried out in the context of clinical trials have shown a relationship between survival and health-related quality of life in colorectal cancer patients.Aims: We assessed the prognostic value of health-related quality of life at diagnosis and of its longitudinal evolution on survival in older colorectal cancer patients. Methods: All patients aged >= 65 years, diagnosed with new colorectal cancer between 2003 and 2005 and registered in the Digestive Cancer Registry of Burgundy were eligible. Patients were asked to complete the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at inclusion, three, six …
