Development of a Comprehensive Framework for the Efficiency Measurement of Road Maintenance Strategies using Data Envelopment Analysis
… systems is the effect of the environmental factors (e.g., climate, location, and etc.) and operational factors (e.g., traffic, load, design-construction adequacy, and etc.) on the performance of the road maintenance process. This issue, again, indicates the need for a performance measurement …

Routing and scheduling models for robust allocation of slack
A myriad of uncontrollable factors in airline operations make delays and disruptions unavoidable. Most conventional scheduling models, however, ignore the presence of uncertainties in actual operations in order to limit the complexity of the problem. This leads to schedules that are prone to delays …

Attributional Outcomes: The Subtle Messages of Treatments for Attention Deficit Disorder
… that solutions would result form external and uncontrollable factors. No group differences were found at posttest on achievement attributions measures or on measures of behavioral or cognitive improvements. The motivational effects of combining medication with psychotherapy or other behavior …

What impact does an attendance incentive program have on student attendance?
… previous school year. Notwithstanding all of the uncontrollable factors that can affect student attendance such as illness, death in the family or other emergencies, it was concluded that an attendance incentive program that provided interim rewards for perfect attendance on a monthly and …

The Determinants of Children's Achievement: A New Framework
… strategies, attribution for failure to uncontrollable factors, and the expression of negative affect). This maladaptive response to failure was found to be ameliorated under conditions which emphasized the utility of knowledge acquired from the achievement task.

Buffer optimization and robust design studies in asynchronous assembly systems using design of experiments approach
… and to design AAS that are robust to noise factors. In order to determine an optimal area of buffers in which the throughput yields to maximum, the design of experiments (DoE) approach and discrete-event simulation are used, and appropriate buffer levels are identified accordingly. Studies …

The implementation of TQM models in an unstable macro-environment
… plan, because there are internal organisational factors that affect the TQM implementation process. Additionally, according to PESTEL analysis, external macro-environmental factors have an impact on an organisation, and its processes. These factors are; Political, Economic, Sociological, …

Data envelopment analysis for measuring the efficiency of head trauma care in England and Wales
… (SEM) in order to investigate the effects of uncontrollable variables on efficiencies. While the use of DEA provides valuable results, our SEM analysis reveals additional findings that were not identified in previous studies. For example, unlike previous second stage analysis studies in DEA …

Sustainability of the Service-Profit Chain
… augments the SPC with another component — uncontrollable factors (environmental variables and competition) that are exogenous to the operation but definitely have an effect on the service delivery process. Further, this research develops a dynamic model to evaluate investments made in …

Estimation and Determination of Carrying Capacity in Loblolly Pine
… on stand BA carrying capacity. Because some uncontrollable factors on long-term operational experiments can make estimates of stand BA carrying capacity unreliable for loblolly pine, it is suggested that the stand BA carrying capacity could be estimated from high initial planting density …

Assessing Organic Matter Breakdown and Associated Macroinvertebrate Community Structure in Headwater Streams: Effects of Hydrologic Gradients and Upland Timber Harvesting
… full ecosystem response and recovery. Due to uncontrollable factors, I was not able to evaluate the success of different SMZ widths. Results documented should be treated with hesitancy, until full ecosystem response has been documented.

Measuring the Efficiency of Highway Maintenance Operations: Environmental and Dynamic Considerations
… estimated efficiency scores, and the effect of uncontrollable variables; (ii) the application of the engineering approach by developing a dynamic micro-level simulation model for the highway deterioration and renewal processes and its coupling with calibration and optimization to find optimum …

Securitisation of mortgage loans, regulatory capital arbitrage and bank stability in South Africa: Econometric and theoretic analyses
… stability will remain partially uncertain due to uncontrollable factors such as the economic conditions. The concept of legitimacy, from Institutional Theory, explicated that banks’ legitimacy came from their ability to comply with the regulations. From this stance, the results suggested that …
