    This book is open access under a CC BY 4.0 license This open access book brings together the latest genome base prediction models currently being used by statisticians, breeders and data scientists. It provides an accessible way to understand the theory behind each statistical learning tool, the required pre-processing, the basics of model building, how to train statistical learning methods, the basic R scripts needed to implement each statistical learning tool, and the output of each tool. To do so, for each tool the book provides background theory, some elements of the R statistical software for its implementation, the conceptual underpinnings, and at least two illustrative examples with data from real-world genomic selection experiments. Lastly, worked-out examples help readers check their own comprehension. The book will greatly appeal to readers in plant (and animal) breeding, geneticists and statisticians, as it provides in a very accessible way the necessary theory, the appropriate R code, and illustrative examples for a complete understanding of each statistical learning tool. In addition, it weighs the advantages and disadvantages of each tool

    The progress of data mining technology and large public popularity establish a need for a comprehensive text on the subject. The series of books entitled by "Data Mining" address the need by presenting in-depth description of novel mining algorithms and many useful applications. In addition to understanding each section deeply, the two books present useful hints and strategies to solving problems in the following chapters. The contributing authors have highlighted many future research directions that will foster multi-disciplinary collaborations and hence will lead to significant development in the field of data mining

    Emergent quality issues in the supply of Chinese medicinal plants: A mixed methods investigation of their contemporary occurrence and historical persistence

    Quality issues that emerged centuries ago in Chinese medicinal plants (CMP) were investigated to explore why they still persist in an era of advanced analytical testing and extensive legislation so that a solution to improve CMP quality could be proposed. This is important for 85% of the world鈥檚 population who rely on medicinal plants (MP) for primary healthcare considering the adverse events, including fatalities that arise from such quality issues. CMP are the most prevalent medicinal plants globally. This investigation used mixed-methods, including 15 interviews with CMP expert key informants (KI), together with thematic analysis that identified the main CMP quality issues, why they persisted, and informed solutions. An unexplained case example, Eleutherococcus nodiflorus (EN), was analysed by collection of 106 samples of EN, its known toxic adulterant Periploca sepium (PS), and a related substitute, Eleutherococcus senticosus (ES), across mainland China, Taiwan and the UK. Authenticity of the samples was determined using High-performance thinlayer chromatography. Misidentification, adulteration, substitution and toxicity were the main CMP quality issues identified. Adulteration was found widespread globally with 57.4% EN found authentic, and 24.6% adulterated with cardiotoxic PS, mostly at markets and traditional pharmacies. The EN study further highlighted that the reason CMP quality issues persisted was due to the laboratory-bound nature of analytical methods and testing currently used that leave gaps in detection throughout much of the supply chain. CMP quality could be more effectively tested with patented analytical technology (PAT) and simpler field-based testing including indicator strip tests. Education highlighting the long-term economic value and communal benefit of delivering better quality CMP to consumers was recommended in favour of the financial motivation for actions that lead to the persistence of well-known and recurrent CMP quality issues

    Theology & technology: An Exploration of their relationship with special reference to the work of Albert Borgmann and intelligent transportation systems

    Get PDF
    This thesis summarizes a large body of literature concerning the sociology, 褉hilosophy, and history of technology and the specific set of technologies concerned with Intelligent Transportation Systems (ITS). It considers technologies of various kinds within the Old and New Testaments and how technology has been understood and occasionally discussed by contemporary theologians. Intelligent Transportation Systems are a very prominent area of modem technologies that will shape the future of society in profound ways. The overall field of ITS is described and then a specific case study concerning a set of automated highway systems applications within three states and two large national parks within the United States is presented. The case study then provides a backdrop to explore specific ways in which theology might engage in a conversation with intelligent transportation systems specifically and technology more generally. Since theologians have written relatively little about technology, we draw upon the work of a leading philosopher of technology who is informed by his Christian commitments, Albert Borgmaim. The extensive philosophy of Bergmann about technology and the character of contemporary life is described. Various considerations about how to create, foster, and maintain a sustained dialogue between disparate intellectual traditions and disciplines are suggested. This includes attention to goals for dialogue, respective strengths that various parties bring to the conversation, and the willingness to hear and learn from the other. A framework to categorize interactions between theology and technology is introduced. Borgmann's ideas, coupled with those of other theologians and philosophers are then applied to the case study. The worth of this approach is then assessed in light of what theologians might contribute to discussion and decision-making about technological systems and devices facing toward the future. Consideration is also given to what technology might contribute to the theological enterprise. The investigation demonstrates the importance of such dialogues and the viability of initiating them
