Any analysis is only as convincing as the quality of the underlying data. In this article, the role of data quality is exemplified by its impact on the interpretation of surveillance data, by operations research projects conducted in the training courses of the International Union Against Tuberculosis and Lung Disease, and the lessons learnt through them. It provides information why double-entr...

This paper is a contribution to the theoretical foundations of strategies. We first present a general definition of abstract strategies which is extensional in the sense that a strategy is defined explicitly as a set of derivations of an abstract reduction system. We then move to a more intensional definition supporting the abstract view but more operational in the sense that it describes a mea...

This paper introduces the Operational Patient Care Pathway which is a unified approach for clinical care to all operational patients arising from the Defence population at risk (PAR) exposed to the 'all-hazards environment' while deployed on military operations. It comprises three organisational models: the Healthcare Cycle, the Chain of Care and the Operational Patient Care Pathway. It is supp...

The term ‘meaning’, as it is presently employed in Linguistics, a polysemous concept, covering broad range of operational definitions. Focussing on two these definitions, meaning ‘concept’ and ‘context’ (also known ‘distributional semantics’), this paper explores to what extent definitions lead converging conclusions regarding the number nature distinct senses form covers. More specifically, in...

Operational risk assessment is a stochastic approach to quantify the operational security of power systems. In this study, interrelation between severity factor and risk, two important parameters in assessment, analyzed. Four different definitions factor, based on results from network studies, are proposed applied, resulting values for indices. The behavior these indices analyzed under varying ...

OBJECTIVE Harmonized data quality (DQ) assessment terms, methods, and reporting practices can establish a common understanding of the strengths and limitations of electronic health record (EHR) data for operational analytics, quality improvement, and research. Existing published DQ terms were harmonized to a comprehensive unified terminology with definitions and examples and organized into a co...

BACKGROUND There is currently no consensus from the relevant stakeholders regarding the operational and construct definitions of child assent for research. As such, the requirements for assent are often construed in different ways, institutionally disparate, and often conflated with those of parental consent. Development of a standardized operational definition of assent would thus be important...

This paper is a contribution to the formal study and analysis of vernacular forms of program derivation. Specifically, in this paper, our vernacular derivations are elementary program transformations over the natural numbers. We provide an intensional semantics for these transformations within the derivations of the Elementary theory of Operations and Numbers, EON, [Bee85]. This semantics is in...

This paper presents a new metamodel based on partially ordered hypersets. The metamodel is minimalist, its only primitives being atoms, potentially infinite hypersets and partial order. The type system is very loose and supports concurrent extensional and intensional definition of types. Every element of the metamodel can be directly referenced, thanks to a powerful automated reification facili...

We present Lang-n-Send, a pi-calculus that is equipped with language definitions. Processes can define languages in operational semantics, and use them to execute programs. Furthermore, processes send receive pieces of semantics through channels. reduction for we offer examples demonstrate some the scenarios Lang-n-Send captures.
