This paper provides formal semantics for an extension of the Object-Role Modeling approach to support declaration of dynamic rules. Dynamic rules differ from static rules by involving state transitions, rather than simply individual states. This paper restricts application of dynamic rules to...

Fact-oriented modeling approaches such as Object-Role Modeling (ORM) include a rich graphical notation for capturing business constraints, allowing modelers to visualize fine details of their data models. These data models should be validated with domain experts who best understand the business...

Since large amount of geospatial data are produced by various sources and stored in incompatible formats, geospatial data integration is difficult because of the shortage of semantics. Despite standardised data format and data access protocols, such as Web Feature Service (WFS), can enable...

Advances in data collection and storage have tremendously increased the presence of functional data, whose graphical representations are curves, images or shapes. As a new area of statistics, functional data analysis extends existing methodologies and theories from the realms of functional...

Since the early 1980s, electricity industry reforms have been initiated in more than half of the countries in the world. Among the primary targets of these reform schemes, there has been an increase in efficiency of the sector; and it is implicitly assumed that government support to energy...

This study applies ordinal confirmatory factor analysis for multiple groups to assess equivalence of scale, random errors and systematic (nonrandom) errors of attitudinal questions surveyed on rating scales under different survey modes (Face-to-Face [F2F], Telephone, Paper, and Web). Empirical...

Purpose – The purpose of this paper is to report on the Global Human Resources People and Strategy Conference. Design/methodology/approach – The paper presents a conference report on the Global Human Resources People and Strategy Conference, which was held in New York, USA from May 6‐9,...

Municipalities around the world are using community energy plans (CEPs) to drive progress towards a more sustainable energy future. Many recognize the supply of local and renewable energy as a crucial component of a resilient future including the potential use of wind power generation. The city...
