This paper concerns the design of temporal relational database schemas. Normal forms play a central role during the design of conventional relational databases, and we have previously extended all existing relational normal forms to apply to temporal relations. However, these normal forms are all atemporal in nature and do not fully take into account the temporal semantics of the attributes of ...

Longitudinality, which is concerned with Primary Health Care (APS) professionals accompanying patients over time, is considered a central feature of this level of health care. The fulfilment of this attribute is related to positive health results, which justify its use for assessing Primary Health Care. On the other hand, the term is not commonly used by Brazilian authors, and in international ...

Conceptual representation of the Old Turkic denominal verb formative {+GAr-} can be characterized with a schema: “ACT + base noun”. It incorporates noun into such that (1) it brings about an action complimentary to quality, attribute or capacity when used without object; (2) object, associating object noun. The reference could either literal metonymical. To support proposition, twenty-two examp...

BACKGROUND Discrete choice experiments (DCEs) are attribute-driven experimental techniques used to elicit stakeholders' preferences to support the design and implementation of policy interventions. The validity of a DCE, therefore, depends on the appropriate specification of the attributes and their levels. There have been recent calls for greater rigor in implementing and reporting on the proc...

In 1994Eleanor Saffran co-authoredwithMyrna Schwartz a seminal review of semantic memory impairments and their implications for the representational format and organisation of conceptual knowledge. In that paper, they argued that conceptual knowledge is distributedacross a network of different sub-systems or ‘‘attribute domains,’’ including at least a perceptual and functional or propositional ...

| This paper provides a systematic and comprehensive study of the underlying semantics of temporal databases, summarizing the results of an intensive collaboration between the two authors over the last ve years. We rst examine how facts may be associated with time, most prominently with one or more dimensions of valid time and transaction time. One common case is that of a bitemporal relation, ...

Most of data in Multi-attribute decision making (MADM) problems are changeable rather than constant and stable. Therefore, sensitivity analysis after problem solving can effectively contribute to making accurate decisions. In this paper, we offer a new method for sensitivity analysis in multi-attribute decision making problems in which if the weights of one attribute changes, then we can dete...
