Development of a prototype for multidimensional performance management in software engineering

Managing performance is an important, and difficult, topic, and tools are needed to help organizations manage their performance. Understanding, and improving performance is an important problem. Performance management has become more and more important for organizations, and managers are always on the lookout for better solutions to manage performance within their organizations. One of the most important consequences of not having a Performance Management Framework (PMF) in place is the difficulty of differentiating organizational success from failure over time. Performance Management Frameworks have become important to organizations that need to plan, monitor, control, and improve their decisions. Use of a PMF can show an organization how it is performing and indicate whether or not an organization is going in the right direction to achieve its objectives. Over the years, several frameworks have been developed to address the management of organizational assets, both tangible and intangible. Performance measurement has always mostly been focused on the economic viewpoint. The framework developed by Kaplan and Norton adds three other viewpoints to this, and this addition represents a significant improvement to PMFs. The PMFs currently proposed do not meet the analytical requirements of software engineering management when various viewpoints must be taken into account concurrently. This difficulty is compounded by the fact that the underlying quantitative data are multidimensional, and so the usual two- and three-dimensional approaches to visualization are generally not sufficient to represent such models. Organizations vary considerably in the wide variety of viewpoints that influence their performance, and every organization has their own viewpoints that they want to manage, and which must be represented in a consolidated manner. The purpose of this thesis is to develop a prototype for managing multidimensional performance in software engineering. The thesis begins by defining the important terms or key concepts used in the research: software, performance, management, model, multidimensional, development, engineering, and prototype, and the various associations of these terms. This is followed by a review of the multidimensional PMFs that are specific to software engineering and the generic multidimensional performance models that are available to management. A framework for managing performance in software engineering in four phases: design, implementation, use of the framework, and performance improvement is then presented. Based on this framework, a prototype tool is developed. The prototype notably includes visual analytical tools to manage, interpret, and understand the results in a consolidated manner, while at the same time keeping track of the values of the individual dimensions of performance. The repository of software project data made available by the International Software Benchmarking Standard Group (ISBSG) is integrated into and used by the prototype as well

Optimized scanning procedures for 4D CT data acquisition in radiation therapy

The goal of conformal radiation techniques is to improve local tumor control through dose escalation to target volumes while at the same time sparing surrounding healthy tissue. Accurate target volume delineation is essential in achieving this goal to avoid inadequate tumor coverage and/or irradiation of an unnecessary volume of healthy tissue. Respiratory motion is known to be the largest intra-fractional organ motion and the most significant source of uncertainty in treatment planning for chest lesions. A method to minimize effects of respiratory motion is to use four-dimensional (4D) radiotherapy.A novel scanning procedure for 4D CT data acquisition is described in this work. Three single-slice helical scans are acquired simultaneously with the real-time tracking of several markers placed on a moving phantom. At the end of the three scans. CT data is binned into different respiratory phases according to the externally recorded respiratory signal and the scanned volume is reconstructed for several respiratory phases. The 4D CT images obtained show an overall improvement when compared to conventional CT images of a moving phantom

Emotional Needs and Schematic Functioning in Depression: A Narrative Review

"Grounded in cognitive theory, the schema therapy model of psychopathology proposes a set of maladaptive cognitive structures, called early maladaptive schemas, resulting from the invalidation of emotional needs. More recently, the schema therapy model has been adapted for use with depressed clients. However, the utility of addressing emotional needs in the psychotherapeutic treatment of depression has not been established. The present paper aims to provide a narrative review of the current literature on basic needs as motivational factors in depression and their relation to schematic functioning. Theoretical considerations and practical evidence on the use of constructs related to basic motivation in depression are drawn from the literature on the cognitive and schema therapy-based models of depression. The implications for the theoretical understanding of needs are discussed, as are future directions for the research of schematic functioning in depression."</jats:p
