In this paper we report on our experience developing the Eye OCL Software (EOS) evaluator, a Java component for efficient OCL evaluation. We first motivate the need for an efficient implementation of OCL in order to cope with novel usages of the language. We then discuss some aspects that, based on our experience, should be taken into account when building an OCL evaluator for medium-large scen...

A partial evaluator is an automatic program transformation tool. Given as input a general program and part of its input, it can produce a specialized version. If the partial evaluator is self-applicable, program generators can be made. The goal is efficiency : the specialized program often runs an order of magnitude faster than the general one. We consider partial evaluation of the pragmatic or...

This is a preliminary report on a self-applicable online partial evaluator for a flowchart language with recursive calls. Self-application of the partial evaluator yields generating extensions that are as efficient as those reported in the literature for offline partial evaluation. This result is remarkable because partial evaluation folklore has indicated that online partial evaluation techniq...

A random sample of American Evaluation Association (AEA) members were surveyed for their reactions to three case scenarios--informed consent, impartial reporting, and stakeholder involvement--in which an evaluator acts in a way that could be deemed ethically problematic. Significant disagreement among respondents was found for each of the scenarios, in terms of respondents' views of whether the...

Comparative evaluation operators for sets and multisets are proposed from a possibilistic point of view. In general, an evaluator estimates the possibility of (non) co-reference of two arbitrary (sub)-objects. Such operators can be used in a hierarchical possibilistic framework for finding co-referent objects with a complex structure. This paper first discusses properties of evaluators in gener...

This paper addresses the problem of querying several databases considered as a whole. Assuming that the different databases share a common data description language, the problem that raises is to consistently answer queries even if the database contents are contradictory. The main contribution of this paper is the specification of a query-evaluator for answering closed and open queries addresse...

Research Summary Seeking causal evidence on biases in idea evaluation, we conducted a field experiment large multinational company with two conditions: (a) blind which managers received no proposer information, and (b) non-blind they the proposer's name, unit, location. To our surprise—and contrast to preregistered hypotheses—we found against women proposers from different units locations, blin...

This study aimed to determine the criteria for quantifying developmental defects of enamel in primary teeth premature babies and investigate severity according gestational age, birth weight, systemic complications, treatments received after preterm birth. Birth information, a history duration parenteral nutrition, endotracheal intubation were investigated by retrospectively reviewing admission ...

This article outlines an efficient runtime representation of evaluation transformers. An evaluator space containing parameterised evaluators for structured and polymorphic types is introduced. Using this framework it is possible to handle runtime information about evaluators for arbitrary structured types as well as evaluation transformers for functions over polymorphic types. In future develop...

A life cycle metaphor characterizes the evolving relationship between the evaluator and program staff. This framework suggests that common developmental dynamics occur in roughly the same order across groups and settings. There are stage-specific dynamics that begin with Pre-History, which characterize the relationship between the grantees and evaluator. The stages are: (a) Pre-History, (b) Pro...
