Bayesian non-parametric models for regional prevalence estimation

We developed a flexible non-parametric Bayesian model for regional disease-prevalence estimation based on cross-sectional data that are obtained from several subpopulations or clusters such as villages, cities, or herds. The subpopulation prevalences are modeled with a mixture distribution that allows for zero prevalence. The distribution of prevalences among diseased subpopulations is modeled as a mixture of finite Polya trees. Inferences can be obtained for (1) the proportion of diseased subpopulations in a region, (2) the distribution of regional prevalences, (3) the mean and median prevalence in the region, (4) the prevalence of any sampled subpopulation, and (5) predictive distributions of prevalences for regional subpopulations not included in the study, including the predictive probability of zero prevalence. We focus on prevalence estimation using data from a single diagnostic test, but we also briefly discuss the scenario where two conditionally dependent (or independent) diagnostic tests are used. Simulated data demonstrate the utility of our non-parametric model over parametric analysis. An example involving brucellosis in cattle is presented.

A conceptual model for compliant management systems

The dissertation specifies a Set of Concepts and a Conceptual Model for Compliant Management Systems (CMSs). The Set of Concepts is drawn from existing methodologies and the CMS Model, which is based on the Concepts, is evaluated against a compiled Set of Standard Requirements. The dissertation is analytical, conceptual and argumentative in nature. The Model is designed to enable the future development of compliant, efficient and globally functional organisational Information Technology (IT) Systems. The Three Central Requirements of the Model – Compliance (essentially a Legal requirement), Efficiency (essentially a Business Management requirement) and Global Functionality (essentially an IT requirement) – necessitated a multi-disciplinary investigation in the Legal, Business Management and IT areas. Compliance was the focus of the research as initial investigations showed no significant solutions existed that provided specific guidelines for the design of inherently compliant IT systems. As compliance relates to meeting regulatory requirements on a local or jurisdictional basis, whereas efficiency and global functionality favour global standards for IT systems (that enable system interoperability), the means for delivering “globally compliant” IT systems is problematic. The research therefore took the approach of “thinking globally and acting locally” by designing a Model appropriate for individual local organisations that can be used, in association with the development of appropriate regulation, as a template for globally compliant IT systems. It was found that the issues of Privacy, Consent, and Accountability were at the core of compliance requirements and that Digital Service Contracts with systematic Authorisation mechanisms for contract parties (represented as IT System “Groups”) provided the means for assuring compliance. The Model proposes software based on Service, Group and Service Contract components – the Service Contract components fulfilling Legal requirements, the Service components fulfilling Business Management requirements and the Group components fulfilling IT requirements. The Model description in the dissertation focuses on the IT System design. Technical (software design) issues are not explored in detail, making the dissertation readable to persons with minimal IT background. The aim was to draw together existing knowledge in the Legal, Business Management and IT disciplines and to explore relationships between the fields at a high level rather than to delve in detail into any of the three disciplines. The research spans many fields within the three research disciplines, including Contract Law, Privacy Law, Company Law, Legal Consent, Franchising Systems, Business Process Management, Service Oriented Architectures, Cloud Computing, Access Control, Authorisation, Operating Systems, Data Management and Object Oriented Programming.
Lean engineering performance measurement model

Today, the application of lean principles is not limited to the shop floor: it is extended to the entire enterprise. Knowledge-based activities, in particular, product development, can significantly benefit from the application of lean principles. R&D intensive organizations such as aerospace have started to implement lean in their product development processes, however, the performance measurement systems that are in place are obsolete and do not promote lean goals and principles. These methods are not capable of measuring the benefits of adopting lean initiatives in the product development process. In this research, a lean engineering performance measurement (LEPM) model is developed that takes into account key lean principles and performance indicators and measures the performance of the engineering process from a lean perspective. This model was implemented in the engineering process of a case company to measure and promote lean initiatives.
The Impact of Stress on Job Satisfaction among Nurses in Jordan University Hospital: Quantitative Research Proposal

Stress is accounted to be a process in which environmental events or forces, known as stressors, threaten an organism’s existence and wellbeing. Several professions with totally different jobs are confronted by different types of stress, that is, impress job environment which resulting affects job performance. The purpose of this paper is to learn how to create a proposal to study the effect of stress on job satisfaction based on Polit & Beck guidelines, 2012) [Saleh, A. (2015). Tool development: Dyspnea.

Electrospinning for the design of medical supplies

In this review, various achievements in the field of development of tissue-engineered scaffolds with the electrospinning approach were observed. Through the appropriate selection of electrospinning parameters, such as solution viscosity, the type of solvent, voltage, the distance between a tip and a collector etc., scaffolds with a high degree of porosity and pore size applicable for optimal cell infiltration can be obtained. These tissue-like materials can be produced from both synthetic and natural polymers and their mixtures. Based on the characteristics specific for the desirable tissue – vascular, bone or cardiac – materials providing the required mechanical properties, architecture, degradation kinetics and biocompatibility are selected for scaffold synthesis. In different studies, electrospun fibers were modified by adding biologically active agents or nanoparticles. This article also describes the particularities of the extracellular matrix of different tissues and approaches used for specific tissue imitation. Repopulation of the matrices with autologous cells before transplantation is the most commonly used method to improve the biocompatibility of the scaffold and the recipient.
Analysis Characteristics of On/Off Grid Tie Inverter and Implementation in Microgrid

One characteristic of microgrid is possible to be integrated with the public electricity network (PLN/grid) or work independently of the public network. Additionally on microgrid is also possible to supply excess power to the grid and still be able to supply power to local load even when disconnected from grid. Not all inverter devices can be used on a microgrid, associated with some of the criteria that must be met. How do the characteristics of on-off grid tie inverter (GTI on-off) and how to build microgrid using on-off GTI became topic of this research activity. Based on results of testing, on-off GTI can be used on microgrid, with ability to supply power to network when excess power or supplied from network at the time of power shortage. As well as on-off GTI is able to work independently when there is no power from network.

Integrated Conditional Moment Estimation and Consistent Model Specification Testing of Static Random Effects Linear Panel Data Models

In this paper we propose a new estimation approach for the static random effects linear panel data model with fixed time dimension, with instruments based on the integrated conditional moment (ICM) principle, which is in essence an instrumental variable approach with infnitely many instruments. The advantages of this new approach are that it allows to estimate the parameters of time-invariant covariates directly and yields a consistent ICM test of the null hypothesis that the model is a proper multivariate conditional expectation model, including the case where the parameters are time-varying. Under this null hypothesis the parameter estimates are strongly consistent, unbiased and asymptotically normal. Moreover, it will be shown that under some regularity conditions these asymptotic normality results also hold for the fixed effects case. The ICM estimation and testing procedures are checked by a limited Monte Carlo analysis. ∗Professor Emeritus of Economics.

design tools and collaborative ideation

This paper presents the results of a comparative study between traditional analogue tools (sketches and physical models), a CAD software (digital) and a hybrid tool (digital and analogue) that allows immersive freehand sketching and model making (the Hybrid Ideation Space), in order to assess their respective abilities to support collaborative ideation. By comparing these tools, we were able to better understand the relationship between the activity of collaborative ideation, the tools that support it and the experience of the designer in order to provide principles for the development of collaborative tools in design.
Advanced Leader Election for Virtual Traffic Lights

We examine the network performance of algorithms for self-organized traffic management. In particular, we focus on wireless network-ing between cars. One of many technologies that make road traffic safer and more efficient is the Virtual Traffic Light(VTL) system,which is able to coordinate the traffic flow at intersections without the need for physical lights. VTL takes a leading vehicle at an inter-section and uses it to control the traffic lights. We developed algorithms for leader election and traffic light computation in realistic ve-hicular networking scenarios. Our key contribution is the extension of this algorithm to support arbitrary intersection layouts. We in-vestigated the proposal in synthetic and realistic scenarios. The results show that, overall, VTLs use network resources efficiently andpositively influences driving experience. It performs better than stationary traffic lights for a low to medium network load. We alsoidentify potential optimizations to deal with high network load and to improve fairness.
The effect of living arrangement on dietary intake of athletes who participated in Special Olympics living in Delaware County, Indiana

The purpose of this study was to measure and compare athletes’ dietary intake to the National Health and Nutrition Examination Survey (NHANES) data that represents individuals without intellectual disabilities (ID), and to determine the effect of living arrangements on dietary intake and diet quality of the athletes. Dietary intakes from the athletes’ three-day food records, previously collected in 2009, were analyzed using the Self Administered 24-hr Recall (ASA24). Results indicated individuals with ID have a poorer quality diet than Americans without ID. Overall, the lowest HEI-2005 score (e.g., poorest diet quality) was observed among the subjects who lived in the family home (41.4 ± 7.6) and the highest HEI-2005 score was observed among the subjects who lived in a group home (45.3 ± 6.4). Results show that the more food choice responsibility given to an individual with ID the lower the quality diet, and the less responsibility given to an individual with ID the higher the quality diet (p≤0.01). Determining the nutrient intake and diet quality of individuals with ID may help identify ways to reduce the rate of obesity in this population, and provide health professionals with information needed to develop appropriate educational efforts.
Degrees of Freedom Analysis of the Non-coherent Block Fading MAC Channel

We study a two-user multiple-input multiple-output (MIMO) fading multiple-access channel (MAC), where two terminals wish to communicate with a third one. The channels between the terminals are MIMO block fading channels with channel coefficients which are constant in a block of length T, and then change in an independent realization. The system model follows the model introduced by Hochwald and Marzetta. We consider a non-coherent channel model, where all terminals are aware of the statistics of the fading but not of its realization. Instead of using pilots for channel estimation, we assume communication where the information is communicated by the use of subspaces, following the geometric approach introduced by Zheng and Tse. We focus on the high signal-to-noise ratio (SNR) regime. In particular, we study the pre-log region, defined as the limiting ratio of the achievable-rate region to log SNR as the SNR tends to infinity.
Parents as Multidimensional Reading Partners for Young Children’s Reading Development: A Scoping Review

This scoping review aims to identify the appropriate roles of parents that can help address problems related reading development amongst young learners. The topic of parents as reading partners needs to be explored given that having the involvement of parents would advantage language learners to minimize their reading problems from different aspects including interest, fluency and comprehension in reading. Parents’ role is in fact, an effective indicator of high language proficiency level. Numerous studies that explored reading development found that most young learners are still facing challenges in mastering different types of reading skills. This problem seems unending despite various approaches, methods and interventions are applied to tackle reading issues among young learners. Therefore, a more practical and reliable way of learning that can cater to students’ individual needs should be devised. A scoping review protocol was established for this study. A total of 42 articles from 2010 to 2020 were qualitatively synthesised. Out of 42 articles, twenty-six articles are on parents’ role in young learners’ reading problems and sixteen articles highlight reading problems aided by parents’ roles were isolated and analysed. The findings suggested that parents’ roles are effective as motivator, tutor and facilitator in aiding children’s reading problems from the aspects of their interest, fluency and comprehension. The involvement of parents in learners’ reading development is beneficial as it also offers reliable references for teachers to adopt in school programmes.
Calculation of external exposure during dismantling and segmentation of steam generator

The prediction of radiation doses obtained during dismantling of steam generator represents one of the most crucial issues within the process of decommissioning of nuclear installations. Given the fact that in Slovakia the nuclear power plant V1 in Jaslovske Bohunice is currently being decommissioned, represents the analysis of the segmentation of steam generator an actual issue. In this paper, the proposed dismantling methodology together with the results of calculations is given. Also the complex analysis of the influence of different distance of workers carrying out the dismantling as well as the influence of the time on the total collective effective dose is carried out. The results of this analysis show that the obtained doses are below the legislative limits and thus the main consequences can be applied in the process of V1 nuclear power plant decommissioning.
PME and Online Education in the Air Force: Raising the Game

Abstract : The U.S. House of Representative s 2010 assessment of professional military education (PME) Another Crossroads? Professional Military Education Two Decades After the Goldwater-Nichols Act and the Skelton Panel was clearly intended to present a comprehensive evaluation of education for U.S. military officers, and in many ways, the report accomplishes that goal admirably. However, Another Crossroads does not assess the area of distance learning in much depth or detail. In fact, the 238-page report contains only nine brief comments or references to distance learning. This lack of detailed consideration of nonresident education was certainly understandable in 1989 when the U.S. House Armed Services Committee issued its first critical assessment of PME in the well-known Skelton Report.2 After all, that was still the era of the traditional correspondence or box of books distance learning method for those who did not attend a PME school in residence.
Direct torque control of switched reluctance motor for minimizing torque ripple

Large torque ripple of the Switched Reluctance Motor (SRM) is a major problem that is an obstacle to spreading over an industry. Nonlinear inductance profile and pulse magnetizing make the torque ripple unavoidable. In order to reduce the torque ripple, it is necessary to control the torque directly because the torque of the SRM is not linearly proportional to a current. This paper shows direct torque control scheme that reduces the torque ripple of the SRM dramatically. To verify the feasibility of control scheme, simulation and experiment are carried out.
Optimized Maintenance Standards for Unpaved Road Networks Based on Cost-Effectiveness Analysis

Unpaved roads play a crucial role in the economic and social development of societies, linking rural communities to education, health services, and markets. The asset value of unpaved roads is low compared with national and provincial road networks, because agencies responsible for rural roads management lack the resources to assess and maintain the network properly. Lack of resources is especially critical in developing countries, where the majority of the population lives in rural areas and where few tools are available for sustainable management of the unpaved network. The main objective for this study was to develop and validate cost-effective maintenance standards for unpaved rural roads. The study was directed at improving the management process of unpaved road networks that serve rural populations. The scope was to develop maintenance standards that can be used by agencies in charge of network management, given available resources and technical skills. The developed four-step methodology evaluates an unpaved road network for 4 years, identifies the effects of maintenance treatments on the condition of roads from field data analysis, defines maintenance strategies, and develops optimal maintenance standards. The study was part of a 4-year project conducted at the University of Waterloo, in Ontario, Canada, that resulted in the development of a sustainable management system for rural road networks in developing countries. The proposed standards were applied and successfully validated and were demonstrated to be adaptable to varying climates, budgets, traffic, and road structures.
Modeling and comparison of the Halbach array with different segments per pole

In this paper the Halbach array with different segments per pole are modeled and compared. The unified harmonic model for the magnetic flux density distribution of the Halbach array with different segments per pole is derived by using Fourier series and magnetic scalar potential. The coil power dissipation and higher harmonics are compared with the Halbach arrays, respectively. The dimension parameter of magnet array is optimized on the basis of minimum coil power dissipation by taking the magnetically levitated planar motor with moving magnets for example. The genetic algorithm is used to minimize the higher harmonics in z-component of the magnetic flux density distribution. Then the dimension parameters of magnet arrays are obtained, according to that the arrays are compared on the ratio between the higher harmonics and analytical model of z-component of the magnetic flux density distribution and the peak value of z -a ndx-component of the magnetic flux density distribution. The Halbach array with 3 segments per pole is chosen on the basis of the above comparison.
The Economic Effects of Dividend Taxation, [by] Kenneth J. McKenzie, Aileen J. Thompson

In this paper we investigate the theoretical rationale for and implications of dividend taxation in a Canadian context. We focus in particular on the implications of dividend taxation for real investment. Three views of dividend taxation are described, each of which has different implications for investment and firm financial policy. Some of the literature which investigates the empirical relevance of these three views is reviewed. We tentatively conclude that there is some support for the “traditional” view that dividend taxes dampen investment. Accepting this as the relevant view, we perform some rough calculations of the impact of eliminating integration in Canada on the cost of capital, and speculate upon the possible investment effects of this hypothetical policy.

Aspectos Didácticos En La Enseñanza De Conceptos Geobotánicos

En el imperio romano cabe destacar la aportación de Plinio que aunque se ocupa esencialmente de plantas cultivadas, realiza numerosos comentarios biogeográficos sobre el paisaje vegetal en su obra "Naturalis Historia". Con la invasión de los bárbaros, se entra en un largo período de recesión en lo que se refiere al conocimiento y uso de las plantas, coincidiendo con un auge de la ganadería que pasa a ser la actividad económica principal.
