Abstract:
The experience of migration includes costs and benefits to migrants and sending communities. In the tradition of a “letters” type discussion, this paper presents a synthesis of recent work from a longitudinal study from Zambia, Africa that used a mixed-methods approach to investigate the experience and outcomes of migration among the Gwembe Tonga. In this ethnographic study, we argue that including anthropometric methods in migration studies enhances our ability to empirically assess impacts of mobility to better understand the experience of migration. In this particular African context we see, on average, a beneficial outcome for migrants’ nutritional status, and livelihoods.

Abstract:
This paper presents multi-criteria methods for ranking project activities according to several ranking indexes. The methods are based on the Analytical Hierarchical Process (AHP), on Data Envelopment Analysis (DEA), and on the use of common ranking indexes. This paper reviews ranking indexes of project activities for project management tasks. The ranking of project activities in one project is applicable for focusing the attention of the project manager on important activities. The selection of the appropriate ranking indexes should be done in accordance with managerial purposes: 1) Paying attention to activities throughout the execution phase and in the resources allocation process, in order meet pre-determined qualities, and to deliver the project on time and within budget, i.e., to accomplish the project within the "iron triangle" 2) Setting priorities in order to share the managerial care and control among the activities. The paper proposes to use multi-criteria ranking methods in order to rank the activities in a case where several ranking indexes are selected.

Abstract:
AbstractMulti-criteria decision analysis (MCDA) is widely used to solve various decision problems through alternative evaluation. MCDA methods can be used in every field that can define a problem, alternatives and criteria. However, finding the appropriate method can influence the results, in this research five MCDA methods have been tested on the renewable energy sector in Latvia to find the best alternative. The main results showed that TOPSIS, VIKOR and PROMETHEE-GAIA have similar priority selection and the highest ranking was selected for hydropower plant, but MULTIMOORA and COPRAS results were beneficial to Solar PV.

Abstract:
This thesis explored the concept of nurses' research literacy – how nurses' read and understand research literature. Through two systematic reviews of the literature, a pilot study and a qualitative research study, insights were formed into how nurses perceive research and how improved research literacy could be facilitated. Forty registered nurses from around Australia shared their experiences of learning about, reading and using research which led to different ways of thinking about teaching research. A new intervention for increasing research literacy, using a language-based, genre-analysis approach, was developed and found to be feasible and effective.

Abstract:
Dans cette thèse nous nous intéressons à plusieurs problèmes de gestion de stocks, à travers des modèles de dimensionnement de lots sur plusieurs niveaux, en tenant compte de capacités de production. Nous étudions tout d’abord un problème de dimensionnement de lots à deux niveaux en série avec des capacités de production identiques et stationnaires aux deux niveaux, pour lequel proposons un algorithme dynamique exact pouvant résoudre le problème en temps polynomial sous certaines hypothèses. Dans le chapitre suivant nous étendons ce résultat dans deux directions : nous considérons le problème de gestion de stocks sur un nombre quelconque de niveaux en série, et nous considérons des livraisons par lots. Nous présentons un algorithme exact de résolution, polynomial et très efficace, basé sur une décomposition originale en composantes connexes induites. Nous considérons ensuite des versions plus générales de ce problème, en établissant des résultats de NP-complétude lorsque chaque niveau à une capacité ou une taille de lot différentes. Nous proposons pour ces problèmes une 2-approximation, basé sur l’encadrement de la fonction objectif par deux fonctions affines. Pour finir nous étudions un problème sur un seul niveau mais dans un système de production composé de machines identiques fonctionnant en parallèle. L’originalité de ce problème est de considérer une limitation de la consommation énergétique. A chaque période, on doit décider combien de machines allumer ou éteindre, et quel volume produire et stocker. Des résultats de complexité sont proposés, montrant que ce problème est NP-difficile même sous des hypothèses fortes, et un algorithme dynamique exact est présenté pour le cas de paramètres d’énergie stationnaires
In this thesis we are interested in several multi-level lot-sizing problems taking into account production capacities. We first study a 2-level in series lot-sizing problem with identical and stationary capacities at both levels, for which we propose an exact dynamic algorithm running in polynomial time under some hypothesis. Next chapter extends this result on two main lines: we consider the multi-level in series lot-sizing problem with batch deliveries and with a number of level which is part of the input. We provide a very efficient exact algorithm for this problem, which is polynomial in the number of levels and in the number of periods, based on an original decomposition into induced connected components. Then, we consider more general versions of this problem, for which we provide NP-hardness results when batch sizes or capacities are level-dependent. We propose 2-approximation algorithms for these problems, based on the sandwiching of the objective function by two affine functions. Finally, we study a single-level lot-sizing problem in a system composed of identical machines working in parallel. The originality of this study is to consider a periodic energy limitation. At each period it must be decided how many machines to switch on or off and the volume to be produced and stored. Complexity results are provided, showing that this problem is NP-hard, even under some restrictive assumptions, and an exact dynamic algorithm running in polynomial time is proposed for the case of stationary energy parameters

Abstract:
Modern methods of contraception are freely available in Albania, yet contraceptive prevalence among Albanians is relatively low (11%). Abortion on the other hand has long been the mainstay of family planning in the country. Emergency contraception is not very popular in Albania either, even though two different levonorgestrel-only EC pills (NorLevo® and Postinor®) are widely available in Albanian pharmacies. This study aimed to investigate potential factors that influence women’s choices of contraception. In 2016, we conducted a multi-method qualitative study with women and service providers in Albania. Women were invited to report their knowledge of, attitudes toward, and practices surrounding contraception in an online survey. Also, we conducted in-depth semi-structured interviews with key informants to better understand the current reproductive health landscape in the country. Additionally, we conducted structured interviews with pharmacists in Tirana to assess their training and practices with regard to different available contraceptive methods. Misinformation, lack of awareness, fear of judgement and embarrassment, and lack of infrastructure are the strongest influencers of women’s choice of contraception in Albania. Training of health service providers, as well as development of materials for distribution are warranted to improve knowledge and uptake of contraception among women.

Abstract:
Dependency problems for developers are like sneezing for people with pollen allergies during the spring, an everyday problem. This is especially true when working in multi-repositories. The dependency problems that occur do so as a byproduct of enabling developers to work on different components of a project in smaller teams, where everything is version controlled.Nearly all developers use version control systems, such as Git, Mercurial, or Subversion. While version control systems have helped developers for nearly 40 years and are constantly getting updated, there are still functionalities that do not exist. One example of that is having a good way of managing dependencies and allowing developers to download projects without having to handle dependency problems manually. The solutions that version control systems offer to help manage dependencies (e.g., Git’s submodules or Mercurial’s subrepositories), do not enable developers a fail-safe download or build the project if it contains dependency problems.In this study, a case study was conducted at Saab Training and Simulation to explore methods for dependency management as well as discuss and highlight some of the problems that emerge when working with dependencies in multi-repositories.An argument can be made that the functionality of dependency management systems, both package managers and version control systems’ solutions are not up to date on how dependencies are used in the development, during this time.In this paper, a novel approach to dependency management is introduced with the possibility to describe the dependencies dynamically by providing the utility to describes usages of a repository (such as simulation of hardware or the main project). As well as discussing the necessary functionalities that are required to handle such a system.By re-opening the dialog about dependency management as well as describing problems that arise in such environments, the goal is to inspire further research within these areas.

Abstract:
When people 'go to the theatre' we know that they are audiences. When young people go to Contact, however, they might be audiences, performers and/or theatre makers - they might play all three or more roles. Contact's users blur existing concepts and terminology. When we want to know more about theatre audiences, audience research offers models based on the distinction between audiences and theatre makers. If we want to know more about Contact's users, however, a model reflecting the blending of audiences and theatre makers' roles has yet to be developed. This thesis engages with Contact's users. It maps some of their multiple roles and experiences by asking two main questions: What are the practices of the people attending Contact and how can these practices be researched? A range of qualitative methods is necessary in order to investigate the wide variety of Contact's users' roles and experiences. Individual and group interviews are drawn from audience research, creative workshops are drawn from communication studies, and participant observation and visual research from the social sciences. Finally, a new method, Walking Fieldwork, is adapted for the use in theatre. A number of case studies are employed to investigate Contact's users. These case studies involve the observation of young actors during rehearsals and performances, the observation of participants in an outreach project, the investigation of audiences' experiences of two productions, and several short post-show interviews with general Contact audiences. This study found evidence that the relationship between theatre makers and audiences is changing. The term 'theatre user' is introduced as it opens up an area of overlap between the two and fits contemporary practices at Contact more closely. Contact's users function as communities, participants and co-creators. The descriptions of these roles and experiences contained in this thesis are understood as an initial exploration into practices of contemporary theatre users. However, further research is needed to build a more detailed understanding of these practices. In terms of research methods, this study found that the academic field of audience research needs to develop methods which are sensitive to both the backgrounds of theatre users and the theatrical context. The argument is put forward that audience research should become more aware of methods for the investigation of human experience and should enter into a 'methods-dialogue' with other academic fields of study.

Full text
Abstract:
Background: Mentoring is an intervention for implementing evidence into practice, but little is known about this intervention. The overall aim of this dissertation was to examine mentoring as a knowledge translation (KT) intervention to inform clinical practice. Methods: 1) A systematic review was used to determine the effectiveness of mentoring as a KT intervention. 2) An interpretive descriptive qualitative study was conducted to explore the use of mentoring in the Registered Nurses' Association of Ontario’s Best Practice Guidelines Implementation/ Knowledge Transfer Fellowship program. Findings: 1) Of 10,669 citations from 1988 to 2012, 10 studies were eligible. Findings showed that mentoring alone (n = 1 study) improved one behavioral outcome. When mentoring was used as part of a multi-faceted intervention (n = 9), there were various effects on knowledge, beliefs/attitudes, use of research evidence in clinical practice, and the impacts on healthcare professionals, patients and organizations. 2) Qualitative interviews with 6 fellows, 8 mentors and 4 program leaders revealed that mentoring involved building relationships, establishing a learning plan, and using teaching and learning activities. Mentors were described as accessible, dedicated, and having expertise; fellows were described as dedicated, self-directed, and having mixed levels of expertise. Mentoring was described as positively impacting upon mentoring relationships, fellows, mentors, and organizations. Participants reported no negative outcomes. Conclusion: Mentoring was used as a KT intervention to support the implementation of evidence into clinical practice. The systematic review and qualitative study findings informed the Mentoring for Guideline Implementation model. Mentoring involved mentees selecting more experienced mentors who provided individualized support based on mentees’ learning needs, which resulted in mutual benefits for mentees and mentors. Future research is required to validate this new mentoring model, develop an instrument to measure the mentor-mentee relationship, and evaluate the effectiveness of mentoring as a KT intervention for guideline implementation in nursing.

Abstract:
Although replication is considered an indispensable part of the scientific method in software engineering, few replication studies are published each year. The rate of replication, however, is not surprising given that replication theory in software engineering is immature. Not only are replication taxonomies varied and difficult to reconcile, but opinions on the role of replication contradict. In general, we have no clear sense of how to build knowledge via replication, particularly given the practical realities of our research field. Consequently, most replications in software engineering yield little useful information. In particular, the vast majority of external replications (i.e., replications performed by researchers unaffiliated with the original study) not only fail to reproduce the original results, but defy explanation. The net effect is that, as a research field, we consistently fail to produce usable (i.e., transferable) knowledge, and thus, our research results have little if any impact on industry. In this dissertation, we dissect the problem of replication into four primary concerns: 1) rate and explicitness of replication; 2) theoretical foundations of replication; 3) tractability of methods for context analysis; and 4) effectiveness of inter-study communication. We address each of the four concerns via a two-part research strategy involving both a theoretical and a practical component. The theoretical component consists of a grounded theory study in which we integrate and then apply external replication theory to problems of replication in empirical software engineering. The theoretical component makes three key contributions to the literature: first, it clarifies the role of replication with respect to the overall process of science; second, it presents a flexible framework for reconciling disparate replication terminology; and third, it informs a broad range of practical replication concerns. The practical component involves a series of replication studies, through which we explore a variety of replication concepts and empirical methods, ultimately culminating in the development of a tractable method for context analysis (TCA). TCA enables the quantitative evaluation of context variables in greater detail, with greater statistical power, and via considerably smaller datasets than previously possible. As we show (via a complex, real-world example), the method ultimately enables the empirically and statistically-grounded reconciliation and generalization of otherwise contradictory results across dissimilar replications—which problem has previously remained unsolved in software engineering.

Abstract:
This multi methods research, which is combined both of quantitative and qualitative methods, is about Public Service Announcement (PSA). This study is aimed to find out if something changes in behavior of people and their attitude to social problem in Russia by an impact of PSA and to understand whereby PSA impacts on changes in behavior of people and rise of attention to social problem in Russia. In order to achieve thesis aims, various types of data presented in this research: a survey of   50 people from different age and sex groups and interviews with a workers of two social organizations. To analyze a data, it were used a univariate and bivariate analysis for quantitative data. Analysis of qualitative data is done in a phenomenological way. According to the results, PSA performs its tasks, something it’s changed in people by impact of PSA, people of all ages noted an  influence of PSA on them, they get to know about social problem, begin to think about or changed their behavior, begun to work as volunteers, made a donation. By all this aspects as emotion, feeling, sensation, design, PSA impact on changes in behavior of people and rise of attention to social problem in Russia.  PSA impacts across effective psychological mechanism such as an emotional sphere of personality. Psychological aspects can be divided into cognitive and emotional. Emotion is one of the key factors of the PSAs. It is established that emotional memory is much stronger than other types of memory, affects human behavior. Cognitive component is related to how advertising information is perceived by people. All elements like an illustration, title, text, logo, layout and general features of the image determine the overall effect of advertising. PSA is a display of goodwill of society, its principled position on socially significant values. Social advertising can and should be considered as a mode of operation of social services.

Abstract:
Much of the research into community interpreting has used different methodologies in order to test or explore the same phenomena from different perspectives (Hale and Napier 2013). This approach is typically referred to as mixed-methods or multi-method research. Pöchhacker (2011) considers that the use of mixed methods in interpreting research is appropriate in order to account for the complexity of interpreting processes and practices. This chapter presents an overview of interpreting research methodologies and explores the meaning of mixed methods. It then discusses a mixed-methods, longitudinal multi-stage project comprising a series of studies conducted by the authors that investigated the feasibility of deaf signers serving as jurors using professional sign language interpreting services. By showcasing our own studies and why these interlinked projects employed mixed methods, we highlight the benefits of exploring various approaches to interpreting research generally.

Abstract:
Hydro-Generator Sets Condition Monitoring and Predictive Maintenance activity has increased dramatically over the past few years. The Fault Diagnostic System is the key technique for the Predictive Maintenance. This paper discusses the Fault Diagnostic System function structure, system design and inferential strategy of Multi-Fault Diagnostic System of the Hydro-Generator Sets. The developing of the power system to big unit requires the higher automation and reliability of the power station. Electrical power systems are constantly exposed to faults and disturbances. This may lead to damage or it may pose a threat to reliable power system operation if a faulty cannot be quickly isolated from the system operation. In accordance with diversity and complexity of Hydro-Generator Sets faults, this paper brings forward a type of fault diagnosis method based on Multi-Diagnosis methods. The Multi-Diagnosis system is constituted of two Sub-Diagnosis systems: one is On-Line Sub-Diagnosis system that based on Bayesian Network (BN) just for the modeling with Bayesian Network has been a powerful tool to solve many uncertainty problems and also with the ability of predicting the future diagnosis; the other is Off-Line Sub-Diagnosis System that based on Model of a hydraulic Turbine-Generator Rotor-Bearing. In order to apply the Bayesian Network model to the engineering fields, we have to solve the problem of constructing the Bayesian Network. Then it suggests a method of constructing Bayesian Network based on the Fault Trees that widely used by the engineers. Base on the construction method, we will construct the Bayesian Network quickly, and Bayesian Network is more suitable for Hydro-Generator Sets fault diagnosis. In accordance with the On-Line Diagnosis Sub-System, it adopts Case-Based Reasoning to make the decision of final diagnosis result or further diagnosis. However, the method mentioned above is limited because of its bottleneck of the knowledge acquisition. The model strategy of the Rotor-Bearing system of Hydro-Generator is discussed and a multi-degree-freedom nonlinear model is developed. It proposes the simulation in accordance with the three fields such as: waterpower, electric and machine. Mechanical, electrical and hydraulic forces acting on rotor externally can be taken into account during the model calculating process. The transient responses of the system are calculated by combined used the transfer matrix method. This paper brings forward a prototype of Hydro-Generator Sets Fault Diagnostic System in order to make a more efficient fault diagnostic decision.

Abstract:
We study the use of multi-level Monte Carlo methods for wind engineering. This report brings together methodological research on uncertainty quantification and work on target applications of the ExaQUte project in wind and civil engineering. First, a multi-level Monte Carlo for the estimation of the conditional value at risk and an adaptive algorithm are presented. Their reliability and performance are shown on the time-average of a non-linear oscillator and on the lift coefficient of an airfoil, with both preset and adaptively refined meshes. Then, we propose an adaptive multi-fidelity Monte Carlo algorithm for turbulent fluid flows where multilevel Monte Carlo methods were found to be inefficient. Its efficiency is studied and demonstrated on the benchmark problem of quantifying the uncertainty on the drag force of a tall building under random turbulent wind conditions. All numerical experiments showcase the open-source software stack of the ExaQUte project for large-scale computing in a distributed environment.

Outcome Measure Harmonization and Data Infrastructure for Patient-Centered Outcomes Research in Depression: Report on Registry Configuration. Agency for Healthcare Research and Quality (AHRQ), November 2020. http://dx.doi.org/10.23970/ahrqepcregistryoutcome.

Full text
Abstract:
Background: Major depressive disorder is a common mental disorder. Many pressing questions regarding depression treatment and outcomes exist, and new, efficient research approaches are necessary to address them. The primary objective of this project is to demonstrate the feasibility and value of capturing the harmonized depression outcome measures in the clinical workflow and submitting these data to different registries. Secondary objectives include demonstrating the feasibility of using these data for patient-centered outcomes research and developing a toolkit to support registries interested in sharing data with external researchers. Methods: The harmonized outcome measures for depression were developed through a multi-stakeholder, consensus-based process supported by AHRQ. For this implementation effort, the PRIME Registry, sponsored by the American Board of Family Medicine, and PsychPRO, sponsored by the American Psychiatric Association, each recruited 10 pilot sites from existing registry sites, added the harmonized measures to the registry platform, and submitted the project for institutional review board review Results: The process of preparing each registry to calculate the harmonized measures produced three major findings. First, some clarifications were necessary to make the harmonized definitions operational. Second, some data necessary for the measures are not routinely captured in structured form (e.g., PHQ-9 item 9, adverse events, suicide ideation and behavior, and mortality data). Finally, capture of the PHQ-9 requires operational and technical modifications. The next phase of this project will focus collection of the baseline and follow-up PHQ-9s, as well as other supporting clinical documentation. In parallel to the data collection process, the project team will examine the feasibility of using natural language processing to extract information on PHQ-9 scores, adverse events, and suicidal behaviors from unstructured data. Conclusion: This pilot project represents the first practical implementation of the harmonized outcome measures for depression. Initial results indicate that it is feasible to calculate the measures within the two patient registries, although some challenges were encountered related to the harmonized definition specifications, the availability of the necessary data, and the clinical workflow for collecting the PHQ-9. The ongoing data collection period, combined with an evaluation of the utility of natural language processing for these measures, will produce more information about the practical challenges, value, and burden of using the harmonized measures in the primary care and mental health setting. These findings will be useful to inform future implementations of the harmonized depression outcome measures.

United Nations University Institute for Water, Environment and Health, December 2021. http://dx.doi.org/10.53328/uxuo4751.

Full text
Abstract:
The report provides a review of how risk is conceived of, modelled, and mapped in studies of infectious water, sanitation, and hygiene (WASH) related diseases. It focuses on spatial epidemiology of cholera, malaria and dengue to offer recommendations for the field of WASH-related disease risk mapping. The report notes a lack of consensus on the definition of disease risk in the literature, which limits the interpretability of the resulting analyses and could affect the quality of the design and direction of public health interventions. In addition, existing risk frameworks that consider disease incidence separately from community vulnerability have conceptual overlap in their components and conflate the probability and severity of disease risk into a single component. The report identifies four methods used to develop risk maps, i) observational, ii) index-based, iii) associative modelling and iv) mechanistic modelling. Observational methods are limited by a lack of historical data sets and their assumption that historical outcomes are representative of current and future risks. The more general index-based methods offer a highly flexible approach based on observed and modelled risks and can be used for partially qualitative or difficult-to-measure indicators, such as socioeconomic vulnerability. For multidimensional risk measures, indices representing different dimensions can be aggregated to form a composite index or be considered jointly without aggregation. The latter approach can distinguish between different types of disease risk such as outbreaks of high frequency/low intensity and low frequency/high intensity. Associative models, including machine learning and artificial intelligence (AI), are commonly used to measure current risk, future risk (short-term for early warning systems) or risk in areas with low data availability, but concerns about bias, privacy, trust, and accountability in algorithms can limit their application. In addition, they typically do not account for gender and demographic variables that allow risk analyses for different vulnerable groups. As an alternative, mechanistic models can be used for similar purposes as well as to create spatial measures of disease transmission efficiency or to model risk outcomes from hypothetical scenarios. Mechanistic models, however, are limited by their inability to capture locally specific transmission dynamics. The report recommends that future WASH-related disease risk mapping research: - Conceptualise risk as a function of the probability and severity of a disease risk event. Probability and severity can be disaggregated into sub-components. For outbreak-prone diseases, probability can be represented by a likelihood component while severity can be disaggregated into transmission and sensitivity sub-components, where sensitivity represents factors affecting health and socioeconomic outcomes of infection. -Employ jointly considered unaggregated indices to map multidimensional risk. Individual indices representing multiple dimensions of risk should be developed using a range of methods to take advantage of their relative strengths. -Develop and apply collaborative approaches with public health officials, development organizations and relevant stakeholders to identify appropriate interventions and priority levels for different types of risk, while ensuring the needs and values of users are met in an ethical and socially responsible manner. -Enhance identification of vulnerable populations by further disaggregating risk estimates and accounting for demographic and behavioural variables and using novel data sources such as big data and citizen science. This review is the first to focus solely on WASH-related disease risk mapping and modelling. The recommendations can be used as a guide for developing spatial epidemiology models in tandem with public health officials and to help detect and develop tailored responses to WASH-related disease outbreaks that meet the needs of vulnerable populations. The report’s main target audience is modellers, public health authorities and partners responsible for co-designing and implementing multi-sectoral health interventions, with a particular emphasis on facilitating the integration of health and WASH services delivery contributing to Sustainable Development Goals (SDG) 3 (good health and well-being) and 6 (clean water and sanitation).

Full text
Abstract:
Rolling waves of consolidation have significantly decreased the number of hospital systems in the U.S. potentially affecting industry quality, prices, efficiency, wages and more. This research concerns the growth in hospital system consolidation in local labor markets and its effect on registered nurse wages. We first use a nonparametric preprocessing data step via matching methods to define MSA-specific samples of workers analogous to nurses outside of the hospital sector. This step enables an accounting of heterogeneous MSA-specific baseline wage growth, and yields a standardized measure of nurse wage growth across MSAs used to set up a multi-site quasi-experiment. We then run a parsimonious linear model; market size matters, for every 0.1 increase in consolidation in smaller-MSAs, real hourly nurse wage growth decreased by $0.70 (p-value of 0.038). Though not the primary aim of this study, a secondary finding is that real hourly wages for nurses grew less than that of comparable workers by $4.08.

Full text
Abstract:
The main objectives of this research was to detect the specific polymorphisms responsible for observed quantitative trait loci and develop optimal strategies for genomic evaluations and selection for moderate (Israel) and large (US) dairy cattle populations. A joint evaluation using all phenotypic, pedigree, and genomic data is the optimal strategy. The specific objectives were: 1) to apply strategies for determination of the causative polymorphisms based on the “a posteriori granddaughter design” (APGD), 2) to develop methods to derive unbiased estimates of gene effects derived from SNP chips analyses, 3) to derive optimal single-stage methods to estimate breeding values of animals based on marker, phenotypic and pedigree data, 4) to extend these methods to multi-trait genetic evaluations and 5) to evaluate the results of long-term genomic selection, as compared to traditional selection. Nearly all of these objectives were met. The major achievements were: The APGD and the modified granddaughter designs were applied to the US Holstein population, and regions harboring segregating quantitative trait loci (QTL) were identified for all economic traits of interest. The APGD was able to find segregating QTL for all the economic traits analyzed, and confidence intervals for QTL location ranged from ~5 to 35 million base pairs. Genomic estimated breeding values (GEBV) for milk production traits in the Israeli Holstein population were computed by the single-step method and compared to results for the two-step method. The single-step method was extended to derive GEBV for multi-parity evaluation. Long-term analysis of genomic selection demonstrated that inclusion of pedigree data from previous generations may result in less accurate GEBV. Major conclusions are: Predictions using single-step genomic best linear unbiased prediction (GBLUP) were the least biased, and that method appears to be the best tool for genomic evaluation of a small population, as it automatically accounts for parental index and allows for inclusion of female genomic information without additional steps. None of the methods applied to the Israeli Holstein population were able to derive GEBV for young bulls that were significantly better than parent averages. Thus we confirm previous studies that the main limiting factor for the accuracy of GEBV is the number of bulls with genotypes and progeny tests. Although 36 of the grandsires included in the APGD were genotyped for the BovineHDBeadChip, which includes 777,000 SNPs, we were not able to determine the causative polymorphism for any of the detected QTL. The number of valid unique markers on the BovineHDBeadChip is not sufficient for a reasonable probability to find the causative polymorphisms. Complete resequencing of the genome of approximately 50 bulls will be required, but this could not be accomplished within the framework of the current project due to funding constraints. Inclusion of pedigree data from older generations in the derivation of GEBV may result is less accurate evaluations.

Full text
Abstract:
This report is one of a series of reports documenting the methods and findings of a multi-year, multi-disciplinary project coordinated by the Pacific Earthquake Engineering Research Center (PEER) and funded by the California Earthquake Authority (CEA). The overall project is titled “Quantifying the Performance of Retrofit of Cripple Walls and Sill Anchorage in Single-Family Wood-Frame Buildings,” henceforth referred to as the “PEER–CEA Project.” The overall objective of the PEER–CEA project is to provide scientifically-based information (e.g., testing, analysis, and resulting loss models) that measure and assess the effectiveness of seismic retrofit to reduce the risk of damage and associated losses (repair costs) of wood-frame houses with cripple wall and sill anchorage deficiencies as well as retrofitted conditions that address those deficiencies. Tasks that support and inform the loss-modeling effort are: (1) collecting and summarizing existing information and results of previous research on the performance of wood-frame houses; (2) identifying construction features to characterize alternative variants of wood-frame houses; (3) characterizing earthquake hazard and ground motions at representative sites in California; (4) developing cyclic loading protocols and conducting laboratory tests of cripple wall panels, wood-frame wall subassemblies, and sill anchorages to measure and document their response (strength and stiffness) under cyclic loading; and (5) the computer modeling, simulations, and the development of loss models as informed by a workshop with claims adjustors. This report is a product of Working Group 3.2 and focuses on Loading Protocol Development for Component Testing. It presents the background, development process, and recommendations for a quasi-static loading protocol to be used for cyclic testing of cripple wall components of wood-frame structures. The recommended loading protocol was developed for component testing to support the development of experimentally informed analytical models for cripple wall components. These analytical models are utilized for the performance-based assessment of wood-frame structures in the context of the PEER–CEA Project. The recommended loading protocol was developed using nonlinear dynamic analysis of representative multi-degree-of-freedom (MDOF) systems subjected to sets of single-component ground motions that varied in location and hazard level. Cumulative damage of the cripple wall components of the MDOF systems was investigated. The result is a testing protocol that captures the loading history that a cripple wall may experience in various seismic regions in California.

Abstract:
Application of 3D technologies to the wide range of Geosciences knowledge domains is well underway. These have been operationalized in workflows of the hydrocarbon sector for a half-century, and now in mining for over two decades. In Geosciences, algorithms, structured workflows and data integration strategies can support compelling Earth models, however challenges remain to meet the standards of geological plausibility required for most geoscientific studies. There is also missing links in the institutional information infrastructure supporting operational multi-scale 3D data and model development. Canada in 3D (C3D) is a vision and road map for transforming the Geological Survey of Canada's (GSC) work practice by leveraging emerging 3D technologies. Primarily the transformation from 2D geological mapping, to a well-structured 3D modelling practice that is both data-driven and knowledge-driven. It is tempting to imagine that advanced 3D computational methods, coupled with Artificial Intelligence and Big Data tools will automate the bulk of this process. To effectively apply these methods there is a need, however, for data to be in a well-organized, classified, georeferenced (3D) format embedded with key information, such as spatial-temporal relations, and earth process knowledge. Another key challenge for C3D is the relative infancy of 3D geoscience technologies for geological inference and 3D modelling using sparse and heterogeneous regional geoscience information, while preserving the insights and expertise of geoscientists maintaining scientific integrity of digital products. In most geological surveys, there remains considerable educational and operational challenges to achieve this balance of digital automation and expert knowledge. Emerging from the last two decades of research are more efficient workflows, transitioning from cumbersome, explicit (manual) to reproducible implicit semi-automated methods. They are characterized by integrated and iterative, forward and reverse geophysical modelling, coupled with stratigraphic and structural approaches. The full impact of research and development with these 3D tools, geophysical-geological integration and simulation approaches is perhaps unpredictable, but the expectation is that they will produce predictive, instructive models of Canada's geology that will be used to educate, prioritize and influence sustainable policy for stewarding our natural resources. On the horizon are 3D geological modelling methods spanning the gulf between local and frontier or green-fields, as well as deep crustal characterization. These are key components of mineral systems understanding, integrated and coupled hydrological modelling and energy transition applications, e.g. carbon sequestration, in-situ hydrogen mining, and geothermal exploration. Presented are some case study examples at a range of scales from our efforts in C3D.
