The use of analytic rubrics remains popular in the field of writing assessment. Previous work in second-language writing assessment and other fields like economics suggest that ratings produced using this method may have lower reliability on average than other methods. Currently, there is little research on the reliability of ratings of creative writing, specifically creative writing authored by adults. This study evaluated the reliability of ratings from an analytic rubric against those produced by a comparative method called Randomly Distributed Comparative Judgment and the rater experience of the methods. The author administered a science fiction and fantasy contest in which 9 raters rated subsets of 47 total contest entries. Raters used both methods on two occasions for a total of four ratings per assigned artifact. The analytic rubric ratings were analyzed using the Many-Facets Rasch Model to model story, rater, occasion, and interaction effects. The comparisons from the RDCJ method were used in a proprietary version of the Bradley-Terry Model to calculate true scores and rater effects. Analysis showed rater effects in the ratings of both methods, though greater for those associated with the rubric model. The ratings from the rubric also contained occasion effects, but the RDCJ ratings did not. Interviews with the raters found that raters generally favored the RDCJ method, though some would have preferred a modified version. However, they all found the rubric less useful, even though many thought that it covered the generally accepted factors of good creative writing. These findings may influence practitioners' decisions when choosing a rating method for shorter works of creative writing, particularly in contexts like story contests or university admissions. However, rating of creative writing is an understudied field compared to academic writing, and more work is needed in the areas of reliability and rating.

Background: Performance-based financing (PBF) is a healthcare reform that is widely adopted in low- and middle-income countries (LMICs). PBF is an intervention designed to strengthen healthcare systems in LMICs. It represents a fundamental shift towards improving healthcare amongst the most vulnerable, with a focus on maternal and child health services. Broadly, there are gaps regarding PBF’s effect on healthcare systems and various aspect of healthcare, including efforts to implement universal healthcare coverage. PBF introduced an innovative component—the PBF equity instrument—geared towards achieving universal health coverage. The effect of this equity instrument has not been studied. There is significant gap regarding how it is defined and implemented in various context. Cameroon has one of the highest maternal mortality rates in sub–Saharan Africa and with high out-of-pocket expenses that impede access to maternal health services. PBF was introduced in Cameroon in 2012 with a focus on maternal health services and was adopted in 2017 as a national strategy towards achieving universal coverage, however, the definition and implementation of the PBF equity elements remain a gap in Cameroon and sub-Saharan Africa. This dissertation is focused on studying the PBF equity elements in Cameroon in order to get a broader perspective on the effect of the PBF equity elements as a policy tool in improving the lives of the most vulnerable population to ensure no one is left behind in the efforts towards achieving universal health coverage. Objectives: This dissertation aimed (1) to investigate and characterize the effect of the PBF equity elements in improving equity in access to selected maternal services (2) to understand how the equity elements is defined and implemented in Cameroon; and (3) to generate a framework that will facilitate the identification of gaps and challenges, in turn informing policy development that is relevant to PBF equity elements in Cameroon and PBF research on equity in other countries; and (4) to explore health providers experiences before and after the introduction of PBF in Cameroon. Methods: This dissertation employed a mixed methods approach to address the above objectives, involving the use of multiple frameworks and triangulation across and within objectives. First, to investigate the effect of PBF on equity in improving access to maternal services, I designed a systematic review with a focus on one of the equity elements—subsidizing user fees to reduce out-of-pocket expenses to improve access to maternal health services. The aim was to get a broader overview of the PBF equity element and to understand the effect of PBF on out-of-pocket expenses in improving access to selected maternal health services in sub–Saharan Africa. Second, I narrowed the assessment to a specific context-Cameroon. Given the heterogenous nature of care delivery in Cameroon, I investigated the effect of PBF on out-of-pocket expenses in improving access to selected maternal health services across healthcare sectors using a before-and-after study design. The rationale was to address the limitations of an earlier PBF impact evaluation in Cameroon, in particular, potential heterogeneity across settings and sectors which had not been considered. Third, to describe and define the implementation of the PBF equity elements in Cameroon, I conducted a grounded theory study -given that it is a new policy that has not been well studied -to understand the social processes and actions from health facilities, health providers, PBF managers and the community, and generated a theoretical framework to inform the challenges and gaps in the implementation process. Finally, as a newly adopted health reform, I conducted an in-depth qualitative study to understand the experiences of health care provides before -and-after the implementation of PBF and its equity elements and the potential for sustainability of the policy especially the equity strategies in Cameroon. Findings: The findings provide an overarching understanding on the effect of one of the PBF equity elements in improving access to maternal health services in sub–Saharan Africa, and in particular, an understanding of the effect of the PBF equity elements in improving access and utilization of selected maternal services in Cameroon. At the health system level, the findings provide an understanding of the focus of the equity elements within the context of Cameroon and further insight on the gaps and limitations in the implementation of the PBF equity elements and the potential challenges in sustainability towards achieving universal health coverage. At the health facility level, it provides an understanding on how the PBF equity elements is understood, defined, and implemented and provides directions on the challenges to inform policy and to guide research. At the individual level, it provides an overview of the expectations of health care providers from a supply side perspective and the potential effect it has on demand creation from women and households in improving access to maternal health services. Overall, the findings provide insight on how the equity elements are defined and implemented but also provides opportunity and areas of improvement and detailed how PBF equity elements can be further assessed and how delays in payment of PBF incentives can potentially affect the realization of the equity elements in improving access and utilization of maternal health services amongst the poor and vulnerable. Conclusion: Equity is central and essential to the delivery of services to achieve universal health coverage. The adoption of PBF in Cameroon is a step toward achieving universal health coverage with the recognition that universal health coverage cannot be effectively implemented in an institution without good governance. The PBF initiative is viewed as an entry point for universal health coverage, in order to evaluate the level of preparedness of health facilities to embrace universal health coverage in terms of quality of health care, production, good managerial skills, and financial management. However, due to administrative bottlenecks, the government has yet to accept some of the established principles of PBF—this in turn causes delays in payment and this hampers the effective implementation of some of the PBF equity strategies. Therefore, though PBF is a national policy, the actors at the central level, i.e., the Ministry of Public Health, are not playing their role effectively in enabling full implementation of PBF best practices and theories.

For the last two decades, the road maintenance concept has been gaining tremendous attention. This has brought about new institutional changes, predominant of which is the challenge for maintenance managers to achieve maximum performance from the existing road system. Such challenge makes it imperative to implement comprehensive systems that measure road maintenance performance. However, the road maintenance performance measurement systems developed and implemented by researchers and state departments of transportation (DOTs) mainly focus on the effectiveness measures, e.g., the level-of-service. Such measurement systems do not sufficiently elaborate on the efficiency concept, e.g., the amount of resources utilized to achieve such level-of-service. Not knowing how "efficient" state DOTs are in being "effective" can lead to excessive and unrealistic maintenance budget expectations. This issue indicates the need for a performance measurement approach that can take the efficiency concept into account. Another important concept that is not investigated in the current road maintenance performance measurement 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 approach that can take such external and uncontrollable factors into account. The purpose of this research is to develop and implement a comprehensive framework that can measure the relative efficiency of different road maintenance strategies given the (i) multiple inputs and outputs that characterize the road maintenance process and (ii) uncontrollable factors (e.g., climate, traffic, etc.) that affect the performance of such process. It is challenging to measure the overall efficiency of a process when such process is a multiple input-multiple output process and when such process is affected by multiple factors. To address this challenge, an innovative approach to efficiency measurement, Data Envelopment Analysis, is used in this research. It is believed that this research, by taking the efficiency concept into account, will significantly improve the ways that are currently used to model and measure the performance of road maintenance. The findings of this research will contribute new knowledge to the asset management field in the road maintenance domain by providing a framework that is able to differentiate effective and efficient maintenance strategies from effective and inefficient ones. / Ph.

In the late 1980s and early 1990s few transportation agencies around the world considered performance-based specifications as an alternative to improve the efficiency of the services provided to the public. These initiatives are better known as Performance-Based Road Maintenance (PBRM). PBRM calls for performance-based work, in which a desired outcome is specified rather than a material or method. This type of specification promises to be an excellent tool to improve government efficiency in maintaining transportation networks; however, without proper monitoring, it could likely yield adverse outcomes. Since PBRM is relatively new, the availability of reliable and comprehensive sets of guidelines to evaluate the effectiveness and efficiency of this type of specifications in the roadway maintenance arena is limited. Transportation agencies currently rely on criteria and procedures they have had developed from their traditional methods used to evaluate performance. Unfortunately, some of these procedures cannot appropriately assess the benefits, if any, accrued by the government as a result of implementing performance-based specifications for the maintenance of the roadway system. This research presents the development of a framework for monitoring PBRM more comprehensively and accurately. The framework considers the assessment of five main areas -- Level of Service Effectiveness, Cost-Efficiency, Timeliness of Response, Safety Procedures, and Quality of Services -- in order to guarantee the comprehensiveness and reliability of the evaluation process. The major contribution of this framework is to provide transportation agencies with guidelines for evaluating the effectiveness and efficiency of PBRM as an alternative delivery method to maintain and preserve the roadway system. / Ph.

There is a need to develop efficient multi-hazard performance based design (PBD) tools to analyze and optimize buildings at a preliminary stage of design. The first step was to develop a database and it is supported by five major contributions: 1) development of nomenclature of variables in PBD; 2) creation of mathematical model to fit data; 3) collection of data; 4) identification of gaps and methods for filling data in PBD; 5) screening of soil, foundation, structure, and envelope (SFSE) combinations.. A unified nomenclature was developed with the collaboration of a multi-disciplinary team to navigate through the PBD. A mathematical model for incremental dynamic analysis was developed to fit the existing data in the database in a manageable way. Three sets of data were collected to initialize the database: 1) responses of structures subjected to hazard; 2) fragility curves; 3) consequence functions. Fragility curves were critically analyzed to determine the source and the process of development of the curves, but structural analysis results and consequence functions were not critically analyzed due to lack of similarities between the data and background information respectively. Gaps in the data and the methods to fill them were identified to lay out the path for the completion of the database. A list of SFSE systems applicable to typical midrise office buildings was developed. Since the database did not have enough data to conduct PBD calculations, engineering judgement was used to screen SFSE combinations to identify the potential combinations for detailed analysis. Through these five contributions this thesis lays the foundation for the development of a database for multi- hazard PBD and identifies potential future work in this area. / Master of Science

With the increased push towards performance-based engineering (PBE) design, there is a need to understand and design more resilient building envelopes when subjected to natural hazards. Since architectural glass curtain walls (CW) have become a popular façade type, it is important to understand how these CW systems behave under extreme loading, including the relationship between damage states and loading conditions. This study subjects 3D computational models of glass CW systems to in- and out-of-plane loading simulations, which can represent the effects of earthquake or hurricane events. The analytical results obtained were used to support fragility curve development which could aid in multi-hazard PBE design of CWs. A 3D finite element (FE) model of a single panel CW unit was generated including explicit modeling of the CW components and component interactions such as aluminum-to-rubber constraints, rubber-to-glass and glass-to-frame contact interactions, and semi-rigid transom-mullion connections. In lieu of modeling the screws, an equivalent clamping load was applied with magnitude based on small-scale experimental test results corresponding to the required screw torque. This FE modeling approach was validated against both an in-plane racking displacement test and out-of-plane wind pressure test from the literature to show the model could capture in-plane and out-of-plane behavior effectively. Different configurations of a one story, multi-panel CW model were generated and subjected to in- and out-of-plane simulations to understand CW behavior at a scale that is hard to test experimentally. The structural damage states the FE model could analyze included: 1) initial glass-to-frame contact; 2) glass/frame breach; 3) initial glass cracking; 4) steel anchor yielding; and 5) aluminum mullion yielding. These were linked to other non-structural damage states related to the CW's moisture, air, and thermal performance. Analytical results were converted into demand parameters corresponding to damage states using an established derivation method within the FEMA P-58 seismic fragility guidelines. Fragility curves were then generated and compared to the single panel fragility curves derived experimentally within the FEMA P-58 study. The fragility curves within the seismic guidelines were determined to be more conservative since they are based on single panel CWs. These fragility curves do not consider: the effects of multiple glass panels with varying aspect ratios; the possible component interactions/responses that may affect the extent of damages; and the continuity of the CW framing members across multiple panels. Finally, a fragility dispersion study was completed to observe the effects of implementing the Derivation method or the Actual Demand Data method prescribed by FEMA P-58, which differ on how they account for different levels of uncertainty and dispersion in the fragility curves based on analytical results. It was concluded that an alternative fragility parameter derivation method should be implemented for fragility curves based on analytical models, since this may affect how conservative the analytically based fragility curves become at a certain probability of failure level. / Master of Science / Performance-based engineering (PBE) can allow engineers and building owners to design a building envelope for specific performance objectives and strength/serviceability levels, in addition to the minimum design loads expected. These envelope systems benefit from PBE as it improves their resiliency and performance during natural multi-hazard events (i.e. earthquakes and hurricanes). A useful PBE tool engineers may utilize to estimate the damages an envelope system may sustain during an event is the fragility curve. Fragility curves allow engineers to estimate the probability of reaching a damage state (i.e. glass cracking, or glass fallout) given a specified magnitude of an engineering demand parameter (i.e. an interstory drift ratio during an earthquake). These fragility curves are typically derived from the results of extensive experimental testing of the envelope system. However, computational simulations can also be utilized as they are a viable option in current fragility curve development frameworks. As it’s popularity amongst owners and architects was evident, the architectural glass curtain wall (CW) was the specific building envelope system studied herein. Glass CWs would benefit from implementing PBE as they are very susceptible to damages during earthquakes and hurricanes. Therefore, the goal of this computational research study was to develop fragility curves based on the analytical results obtained from the computational simulation of glass CW systems, which could aid in multi-hazard PBE design of CWs. As v opposed to utilizing limited, small experimental data sets, these simulations can help to improve the accuracy and decrease the uncertainties in the data required for fragility curve development. To complete the numerical simulations, 3D finite element (FE) models of a glass CW system were generated and validated against experimental tests. 11 multi-panel CW system configurations were then modeled to analyze their effect on the glass CW’s performance during in-plane and out-of-plane loading simulations. These parametric configurations included changes to the: equivalent clamping load, glass thickness, and glass-to-frame clearance. Fragility curves were then generated and compared to the single panel CW fragility curves derived experimentally within the FEMA P-58 Seismic Fragility Curve Development study. The fragility curves within FEMA P-58 were determined to be more conservative since they are based on single panel CWs. These fragility curves do not consider: the effects of multiple glass panels with varying aspect ratios; the possible component interactions/responses that may affect the extent of damages; and the continuity of the CW framing members across multiple panels. Finally, a fragility dispersion study was completed to observe the effects of implementing different levels of uncertainty and dispersion in the fragility curves based on analytical results.
