Software maintenance and mainly software comprehension pose the largest costs in the software lifecycle. In order to assess the cost of software comprehension, various complexity measures have been proposed in the literature. This paper proposes new cognitive-spatial complexity measures, which combine the impact of spatial as well as architectural aspect of the software to compute the software ...

Identifying high cognitive complexity modules can lead to a better quality software system and can help during maintenance also. It has been found that inheritance has an impact on cognitive complexity of a software system. In this paper, two inheritance metrics based on cognitive complexity, one at class level CCI (Class Complexity due to Inheritance) and another at program level ACI (Average ...

Distance Learning is an educational method that uses the Internet to support class discussions and activities. This paper presents a qualitative study that investigates the role changes that occur when classes go online or become “virtual”. We examine several distance learning initiatives that have been implemented in information technology curricula in the past decade. Our analysis is based up...

Exhibit WRIGHT shows a few of Frank Lloyd Wright’s sketches for a collection of cabins contemplated for a development at Lake Tahoe. Wright’s sketches reveal a process of exploration of design alternatives, which is a hallmark of the activity of design. This chapter describes the essential elements of the exploration process. After explaining why exploration is necessary, I describe the concept...

OBJECTIVE To examine whether occupational complexity of working with data or people, and cognitive or social leisure activity at midlife predicted cognition in advanced old age. METHODS We used 810 eligible participants from Longitudinal Study of Living Conditions of the Oldest Old, a Swedish nationally representative study of individuals aged 77+ with cognitive assessments (an abridged versi...

New procedures and technologies of Air Traffic Control (ATC) under development in Next Generation Air Transportation System (NextGen) will change controllers' tasks, roles, and responsibilities. However, cognitive complexity will remain one of the limiting factors in future system's capacity and none of existing complexity metrics can be directly extended to evaluate cognitive complexity under ...
