The objective of the evaluation of the weather forecasting services used by the Iowa Department of Transportation is to ascertain the accuracy of the forecasts given to maintenance personnel and to determine whether the forecasts are useful in the decision-making process and whether the forecasts have potential for improving the level of service. The Iowa Department of Transportation has estimated the average cost of fighting a winter storm to be about $60,000 to $70,000 per hour. This final report is to provide an evaluation report describing the collection of weather data and information associated with the weather forecasting services provided to the Iowa Department of Transportation and its maintenance activities and to determine their impact in winter maintenance decision-making.

Developing leadership in managers to facilitate the implementation of national guideline recommendations : a process evaluation of feasibility and usefulness

Background: Previous research supports the claim that managers are vital players in the implementation of clinical practice guidelines (CPGs), yet little is known about interventions aiming to develop managers’ leadership in facilitating implementation. In this pilot study, process evaluation was employed to study the feasibility and usefulness of a leadership intervention by exploring the intervention’s potential to support managers in the implementation of national guideline recommendations for stroke care in outpatient rehabilitation. Methods: Eleven senior and frontline managers from five outpatient stroke rehabilitation centers participated in a four-month leadership intervention that included workshops, seminars, and teleconferences. The focus was on developing knowledge and skills to enhance the implementation of CPG recommendations, with a particular focus on leadership behaviors. Each dyad of managers was assigned to develop a leadership plan with specific goals and leadership behaviors for implementing three rehabilitation recommendations. Feasibility and usefulness were explored through observations and interviews with the managers and staff members prior to the intervention, and then one month and one year after the intervention. Results: Managers considered the intervention beneficial, particularly the participation of both senior and frontline managers and the focus on leadership knowledge and skills for implementing CPG recommendations. All the managers developed a leadership plan, but only two units identified goals specific to implementing the three stroke rehabilitation recommendations. Of these, only one identified leadership behaviors that support implementation. Conclusion: Managers found that the intervention was delivered in a feasible way and appreciated the focus on leadership to facilitate implementation. However, the intervention appeared to have limited impact on managers’ behaviors or clinical practice at the units. Future interventions directed towards managers should have a stronger focus on developing leadership skills and behaviors to tailor implementation plans and support implementation of CPG recommendations.

The challenges of integrating biodiversity and ecosystem services monitoring and evaluation at a landscape-scale wetland restoration project in the UK

There is an increasing emphasis on the restoration of ecosystem services as well as of biodiversity, especially where restoration projects are planned at a landscape scale. This increase in the diversity of restoration aims has a number of conceptual and practical implications for the way that restoration projects are monitored and evaluated. Landscape-scale projects require monitoring of not only ecosystem services and biodiversity but also of ecosystem processes since these can underpin both. Using the experiences gained at a landscape-scale wetland restoration project in the UK, we discuss a number of issues that need to be considered, including the choice of metrics for monitoring ecosystem services and the difficulties of assessing the interactions between ecosystem processes, biodiversity, and ecosystem services. Particular challenges that we identify, using two pilot data sets, include the decoupling of monetary metrics used for monitoring ecosystem services from biophysical change on the ground and the wide range of factors external to a project that influence the monitoring results. We highlight the fact that the wide range of metrics necessary to evaluate the ecosystem service, ecosystem process, and biodiversity outcomes of landscape-scale projects presents a number of practical challenges, including the need for high levels of varied expertise, high costs, incommensurate monitoring outputs, and the need for careful management of monitoring results, especially where they may be used in making decisions about the relative importance of project aims.

Namibia RSRC Activity Performance Evaluation: Component 1 Report

The Millennium Challenge Corporation (MCC) contracted the Technology & Social Change group (TASCHA) at the University of Washington to conduct a performance evaluation of the Namibia Regional Study and Resource Centers (RSRC) Activity.

The evaluation comprises a set of quantitative and qualitative data collection efforts divided into two categories: Component 1 and Component 2. This report presents the findings for Component 1 only, focusing on evaluating the RSRC planning and implementation activities leading up to the end of the MCA-Namibia Compact in September 2014.

Online MBPeT dashboard : enabling performance testing as a service in the cloud

In this thesis, tool support is addressed for the combined disciplines of Model-based testing and performance testing. Model-based testing (MBT) utilizes abstract behavioral models to automate test generation, thus decreasing time and cost of test creation. MBT is a functional testing technique, thereby focusing on output, behavior, and functionality. Performance testing, however, is non-functional and is concerned with responsiveness and stability under various load conditions. MBPeT (Model-Based Performance evaluation Tool) is one such tool which utilizes probabilistic models, representing dynamic real-world user behavior patterns, to generate synthetic workload against a System Under Test and in turn carry out performance analysis based on key performance indicators (KPI). Developed at Åbo Akademi University, the MBPeT tool is currently comprised of a downloadable command-line based tool as well as a graphical user interface. The goal of this thesis project is two-fold: 1) to extend the existing MBPeT tool by deploying it as a web-based application, thereby removing the requirement of local installation, and 2) to design a user interface for this web application which will add new user interaction paradigms to the existing feature set of the tool. All phases of the MBPeT process will be realized via this single web deployment location including probabilistic model creation, test configurations, test session execution against a SUT with real-time monitoring of user configurable metric, and final test report generation and display. This web application (MBPeT Dashboard) is implemented with the Java programming language on top of the Vaadin framework for rich internet application development. The Vaadin framework handles the complicated web communications processes and front-end technologies, freeing developers to implement the business logic as well as the user interface in pure Java. A number of experiments are run in a case study environment to validate the functionality of the newly developed Dashboard application as well as the scalability of the solution implemented in handling multiple concurrent users. The results support a successful solution with regards to the functional and performance criteria defined, while improvements and optimizations are suggested to increase both of these factors.

External school evaluation : teachers’ perspectives : two case studies from Northern Portugal

The external evaluation of non-higher education schools in Portugal has been developed by the General Inspectorate of Education since 2006. A first cycle of evaluation was completed, covering all educational units in continental Portugal up to 2011. The model of evaluation has since been subject to alterations, and a second cycle of evaluation is now coming to an end. The current model of evaluation is based on documental analysis, analysis of students’ results, and panel interviews with a variety of representatives of the school community, and addresses three domains: results, provision of educational service and management. This paper is part of an ongoing research project, developed by 6 universities and supported by the Portuguese Foundation for Science and Technology (PTDC/CPE-CED/116674/2010) which intends to analyse the impacts and effects this process of external evaluation has had on Portuguese schools. This project includes a variety of perspectives and methodologies. In particular, we will focus on two case studies undertaken in two schools from the northern region of Portugal, and more specifically on the perspectives expressed by the teachers of those schools. These particular schools were chosen because they have been evaluated twice and represent different educational levels (basic and secondary), contexts and results. These case studies included the analysis of documental data, interviews to key informants and a questionnaire directed to teachers (n = 141) – the latter will be the main focus of this paper. Teachers are essential elements of the school community when considering the impacts of external evaluation, as any changes directed at teaching practices, student evaluation, among others are only possible through their direct action and implication. Therefore, their perceptions on the process and its impacts are crucial to the understanding of what does and does not change in schools as a consequence of external evaluation. Although teachers’ opinions are not homogenous and each school reveals a number of differences when it comes to teachers’ perceptions of School Evaluation, it was possible to stress some areas as the most and as the least consensual. Teachers in both schools agree External School Evaluation (ESE) is useful for the identification of the schools’ strengths and weaknesses, values students’ external evaluation results, imposes a model for schools internal evaluation (and in fact contributes to the very existence of internal evaluation practices), and contributes to schools improvement. However teachers in both schools do not believe ESE contributes to teachers’ autonomy produces changes in how curriculum is managed, or leads to innovative teaching practices. These results point to a greater emphasis on change at the levels of school management, self-evaluation and particularly internal evaluation, but little impact on the teaching practices. We believe the classroom is at the core of school practices and teaching processes are essential to any measure of school quality and to their impacts on student learning.

Evaluation use within a humanitarian non-governmental organization’s health care user-fee exemption program in West Africa

L’évaluation de l’action humanitaire (ÉAH) est un outil valorisé pour soutenir l’imputabilité, la transparence et l’efficience de programmes humanitaires contribuant à diminuer les inéquités et à promouvoir la santé mondiale. L’EAH est incontournable pour les parties prenantes de programme, les bailleurs de fonds, décideurs et intervenants souhaitant intégrer les données probantes aux pratiques et à la prise de décisions. Cependant, l’utilisation de l’évaluation (UÉ) reste incertaine, l’ÉAH étant fréquemment menée, mais inutilisé. Aussi, les conditions influençant l’UÉ varient selon les contextes et leur présence et applicabilité au sein d’organisations non-gouvernementales (ONG) humanitaires restent peu documentées. Les évaluateurs, parties prenantes et décideurs en contexte humanitaire souhaitant assurer l’UÉ pérenne détiennent peu de repères puisque rares sont les études examinant l’UÉ et ses conditions à long terme. La présente thèse tend à clarifier ces enjeux en documentant sur une période de deux ans l’UÉ et les conditions qui la détermine, au sein d’une stratégie d’évaluation intégrée au programme d’exemption de paiement des soins de santé d’une ONG humanitaire. L’objectif de ce programme est de faciliter l’accès à la santé aux mères, aux enfants de moins de cinq ans et aux indigents de districts sanitaires au Niger et au Burkina Faso, régions du Sahel où des crises alimentaires et économiques ont engendré des taux élevés de malnutrition, de morbidité et de mortalité. Une première évaluation du programme d’exemption au Niger a mené au développement de la stratégie d’évaluation intégrée à ce même programme au Burkina Faso. La thèse se compose de trois articles. Le premier présente une étude d’évaluabilité, étape préliminaire à la thèse et permettant de juger de sa faisabilité. Les résultats démontrent une logique cohérente et plausible de la stratégie d’évaluation, l’accessibilité de données et l’utilité d’étudier l’UÉ par l’ONG. Le second article documente l’UÉ des parties prenantes de la stratégie et comment celle-ci servit le programme d’exemption. L’utilisation des résultats fut instrumentale, conceptuelle et persuasive, alors que l’utilisation des processus ne fut qu’instrumentale et conceptuelle. Le troisième article documente les conditions qui, selon les parties prenantes, ont progressivement influencé l’UÉ. L’attitude des utilisateurs, les relations et communications interpersonnelles et l’habileté des évaluateurs à mener et à partager les connaissances adaptées aux besoins des utilisateurs furent les conditions clés liées à l’UÉ. La thèse contribue à l’avancement des connaissances sur l’UÉ en milieu humanitaire et apporte des recommandations aux parties prenantes de l’ONG.

Performance evaluation of DCA and SRC on a single bot detection

Malicious users try to compromise systems using new techniques. One of the recent techniques used by the attacker is to perform complex distributed attacks such as denial of service and to obtain sensitive data such as password information. These compromised machines are said to be infected with malicious software termed a “bot”. In this paper, we investigate the correlation of behavioural attributes such as keylogging and packet flooding behaviour to detect the existence of a single bot on a compromised machine by applying (1) Spearman’s rank correlation (SRC) algorithm and (2) the Dendritic Cell Algorithm (DCA). We also compare the output results generated from these two methods to the detection of a single bot. The results show that the DCA has a better performance in detecting malicious activities.

Clinical evaluation of two materials in the restoration of abfraction lesions

Aim: To evaluate the clinical performance of a composite resin (CR) and a resin-modified glassionomer cement (RMGIC) for the treatment of abfraction lesions. Methods: Thirty patients with abfraction lesions in at least two premolar teeth were selected and invited to participate in this study. All restorations were made within the same clinical time frame. One tooth was restored with CR Z100TM (3M, St. Paul, MN, USA), and the other was restored with RMGIC VitremerTM (3M). The restorations were assessed immediately and 1, 6 and 12 months after the restoration, using modified US Public Health Service (USPHS) criteria: marginal integrity, marginal discoloration, wear, retention, secondary caries and hypersensitivity. The statistical analysis was based on Friedman ANOVA test and Mann-Whitney test, considering p<0.05 for statistical significance. Results: Both materials demonstrated satisfactory clinical performance after one year. In the individual analysis of each material, there was a significant difference (p<0.05) in the criteria marginal integrity and wear, for both CR and RMGIC. RMGIC exhibited more damage one year after the restoration. Comparing both materials, it was found a significant difference only for marginal discoloration, while the RMGIC restorations showed the worst prognosis after a year of evaluation. There was no significant difference in the number of retentions, caries or hypersensitivity between CR and RMGIC. Conclusions: It was concluded that CR exhibited the best clinical performance according to the cost-effectiveness and evaluation criteria used in this study.

Girolando breed genetic improvement program - Genetic evaluation of cows - June/2016.

The Girolando breed progeny test was established in 1997, as a result of the partnership between Girolando and Embrapa Dairy Cattle. In 2007, the Programa de Melhoramento Genético da Raça Girolando? PMGG (Genetic Improvement Program of the Girolando Breed) was implemented. Besides interacting with previously existing initiatives of the Girolando Breeders Association, such as the genealogical register service, the progeny test and the dairy control service, the PMGG launched the Linear Evaluation System (SLAG). The main objectives of the PMGG comprises identification of genetically superior individuals, the technically-oriented multiplication of genetics, the evaluation of economic traits and the promotion of sustainable dairy activities. The program have yielded impressive results. The Girolando breed semen sales increases faster than any other breed in Brazil.

A next application prediction service using the BaranC framework

Predicting user behaviour enables user assistant services provide personalized services to the users. This requires a comprehensive user model that can be created by monitoring user interactions and activities. BaranC is a framework that performs user interface (UI) monitoring (and collects all associated context data), builds a user model, and supports services that make use of the user model. A prediction service, Next-App, is built to demonstrate the use of the framework and to evaluate the usefulness of such a prediction service. Next-App analyses a user's data, learns patterns, makes a model for a user, and finally predicts, based on the user model and current context, what application(s) the user is likely to want to use. The prediction is pro-active and dynamic, reflecting the current context, and is also dynamic in that it responds to changes in the user model, as might occur over time as a user's habits change. Initial evaluation of Next-App indicates a high-level of satisfaction with the service.

Automated service provisioning in programmable network infrastructures

Modern networks are undergoing a fast and drastic evolution, with software taking a more predominant role. Virtualization and cloud-like approaches are replacing physical network appliances, reducing the management burden of the operators. Furthermore, networks now expose programmable interfaces for fast and dynamic control over traffic forwarding. This evolution is backed by standard organizations such as ETSI, 3GPP, and IETF. This thesis will describe which are the main trends in this evolution. Then, it will present solutions developed during the three years of Ph.D. to exploit the capabilities these new technologies offer and to study their possible limitations to push further the state-of-the-art. Namely, it will deal with programmable network infrastructure, introducing the concept of Service Function Chaining (SFC) and presenting two possible solutions, one with Openstack and OpenFlow and the other using Segment Routing and IPv6. Then, it will continue with network service provisioning, presenting concepts from Network Function Virtualization (NFV) and Multi-access Edge Computing (MEC). These concepts will be applied to network slicing for mission-critical communications and Industrial IoT (IIoT). Finally, it will deal with network abstraction, with a focus on Intent Based Networking (IBN). To summarize, the thesis will include solutions for data plane programming with evaluation on well-known platforms, performance metrics on virtual resource allocations, novel practical application of network slicing on mission-critical communications, an architectural proposal and its implementation for edge technologies in Industrial IoT scenarios, and a formal definition of intent using a category theory approach.

An architecture for network acceleration as a service in the cloud continuum

The pervasive availability of connected devices in any industrial and societal sector is pushing for an evolution of the well-established cloud computing model. The emerging paradigm of the cloud continuum embraces this decentralization trend and envisions virtualized computing resources physically located between traditional datacenters and data sources. By totally or partially executing closer to the network edge, applications can have quicker reactions to events, thus enabling advanced forms of automation and intelligence. However, these applications also induce new data-intensive workloads with low-latency constraints that require the adoption of specialized resources, such as high-performance communication options (e.g., RDMA, DPDK, XDP, etc.). Unfortunately, cloud providers still struggle to integrate these options into their infrastructures. That risks undermining the principle of generality that underlies the cloud computing scale economy by forcing developers to tailor their code to low-level APIs, non-standard programming models, and static execution environments. This thesis proposes a novel system architecture to empower cloud platforms across the whole cloud continuum with Network Acceleration as a Service (NAaaS). To provide commodity yet efficient access to acceleration, this architecture defines a layer of agnostic high-performance I/O APIs, exposed to applications and clearly separated from the heterogeneous protocols, interfaces, and hardware devices that implement it. A novel system component embodies this decoupling by offering a set of agnostic OS features to applications: memory management for zero-copy transfers, asynchronous I/O processing, and efficient packet scheduling. This thesis also explores the design space of the possible implementations of this architecture by proposing two reference middleware systems and by adopting them to support interactive use cases in the cloud continuum: a serverless platform and an Industry 4.0 scenario. A detailed discussion and a thorough performance evaluation demonstrate that the proposed architecture is suitable to enable the easy-to-use, flexible integration of modern network acceleration into next-generation cloud platforms.

Evaluation Of The Radiopacity Of Esthetic Root Canal Posts.

The radiopacity of esthetic root canal posts may impair the assessment of their fit to the root canal when using radiographic images. This study determined in vitro the radiographic density of esthetic root canal posts using digital images. Thirty-six roots of human maxillary canines were assigned to six groups (N=6 per group): Reforpost (RP); Aestheti-Plus (AP); Reforpost MIX (RPM); D.T. Light Post (LP); Reforpost Radiopaque (RPR); and White Post DC (WP). Standardized digital images of the posts were obtained in different conditions: outside the root canal, inside the canal before and after cementation using luting material, and with a tissue simulator. Analysis of variance was used to compare the radiopacity mean values among the posts outside the root canal and among the posts under the other conditions, and the t unpaired test to compare the radiopacity between the posts and the dentin, and between the posts and the root canal space. There was no statistically significant difference in radiopacity between RP and RPM, and LP and WP. AP posts showed radiopacity values significantly lower than those for dentin. No statistically significant difference was found between posts (RP and AP) and the root canal space. A statistically significant difference was observed between the luted and non-luted posts; additionally, luted posts with and without tissue simulator showed no significant differences. Most of the cement-luted posts analyzed in this study were distinguishable from the density of adjacent dentin surfaces, allowing radiographic confirmation of the fit of the post in the canal. The success of using esthetic root canal posts depends mainly on the fit of the post within the canal.[1] The radiopacity of a post allows for radiographic imaging to be used to determine the fit, an important factor in a clinical perspective.
