A turnaround describes an organization's ability to recover from successive periods of decline. Current and projected declines in US economic conditions continue to place local public health departments at risk of fiscal exigency. This examination focused on turnaround methodologies used by a local public health department to reverse successive periods of operational and financial declines. Ill...

This work proposes a graph mining based approach to mine a taxonomy of events from activities for complex videos which are represented in terms of qualitative spatio-temporal relationships. A Hidden Markov Model to obtain stable qualitative spatial relations from noisy measurements is introduced. The effectiveness of the approach is demonstrated through experimental results for a complex aircra...

In this work, we represent complex video activities as one large activity graph and propose a constraint based graph mining technique to discover a partonomy of classes of subgraphs corresponding to event classes. Events are defined as subgraphs of the activity graph that represent what we regard as interesting interactions, that is, where all objects are actively engaged and are characterized ...

Using a sample of Australian firms, we document improvements in operating performance following performance shocks. These improvements result in part from turnaround strategies adopted by management. Evidence suggests that changes made to leverage and operating expenses result in a negative contemporaneous effect on performance improvement. The adjustments made to working capital (revenue growt...

The ground-level ozone is a pervasive air pollutant, which can be potentially elevated by flaring emissions during chemical plant turnaround operations (i.e., startup and shutdown). Especially in chemical plant concentrated regions, the regional air-quality (i.e., the ozone concentration) may be aggravated by simultaneous turnaround emissions from multiple chemical plants. Thus, under viable ma...

We analyse the factors that led to the turnaround of the Indian Railways from a low performing organisation to a high performing one. Literature on public sector turnaround provides the theoretical underpinnings. Enterprise turnaround is often ascribed to managerial leadership; we found that environmental factors (good luck) also contribute to the success. The implication of our study is that a...

GQM+Strategies is an approach that aligns the business goals at each level of an organization to strategies to achieve overall business goals and assesses the achievement of such goals. Strategies are extracted from business goals based on rationales (contexts and assumptions). Using the proposed approach, which refines the GQM+Strategies model by extracting rationales based on the analysis of ...

To achieve overall business goals, GQM+Strategies® is an approach that aligns the business goals at each level of an organization to strategies and assesses the achievement of goals. Strategies derived from business goals are based on rationales (context factors and assumptions). Because extracting all rationales is an important process in the GQM+Strategies approach, we propose Context-Assumpt...
