Package design is concerned with the determining the best way to partition the classes in a system into subsystems. A poor package design can adversely affect the quality of a software system. In this paper we present a new metric, Class Reachability Set Size (CRSS), the distribution of which can be used to determine if the relationships between the classes in a system preclude it from a good p...

A recent report on the state of the UK information technology (IT) industry based most of its findings and recommendations on expert opinion. It is surprising that the report was unable to incorporate more empirical evidence. This paper aims to assess whether it is necessary to base IT industry and academic policy on expert opinion rather than on empirical evidence. Current evidence related to ...

The predictability of abnormal returns based on information contained in past earnings announcements is a statistically and economically significant anomaly. Neither is it illusory, nor is it an artefact of the experimental design. It may be a result of market inefficiency. Our results cannot rule out this explanation. However, we find that the magnitude of the post-earnings announcement effect...

This paper discusses the dynamic error characteristics of touch trigger probes used with coordinate measuring machines. During the investigation, a number of important parameters have been identified, including measurement speed, probe longitude, approach distance, probe latitude, stylus length/stylus tip diameter, probe orientation, operating mode (scanning and nonscanning), scan pitch, preloa...

The Unified Modeling Language (UML) currently proposes a mechanism to model recurrent design structures: the parameterized collaborations. The main goal of this mechanism is to model the structure of Design Patterns. This is an interesting feature because it can help designers to point out pattern application without spending time with intricate design details. Moreover, it can also help design...
