    Consider processes where a transaction moves through stages and falls within a category at each stage. For example, in a tax complaint process, the stages are the steps taxpayers follow to resolve a property tax dispute from initial complaint through final resolution. The primary motivation here is customer service, although the transactions could be related to manufacturing applications as well. The main contribution here is a method to monitor the fractions and numbers of transactions within and across stages of multistage and multicategory processes, a problem that has not been formulated before in the literature. The proposed method not only signals an out-of-control situation, it identifies accurately and easily which stages and categories are causing the disturbance, providing interpretations within and across stages of the process. The proposed methodology works as follows: If a multinomial distribution fits the number of transactions in each category at every stage, then the process is decomposed into single stages that are monitored separately, and finally into independent binary substages with two categories. Each binary substage is characterized by a conditional probability and monitored with an independent fraction, called a tree fraction. The number of tree fractions that are monitored depends on the number of final categories, i.e., those that do not split in any further categories, not on the number of stages. Two other contributions, summarized next, address the single stage case. Each is useful by itself, and each contributes to the method for the multistage case as well. The first is a new two-sided CUSUM Arcsine method to monitor a process with two categories. The second is the p-tree method that monitors a multinomial process. The p-tree method not only signals an out-of-control situation, it identifies accurately which categories are causing the problem, in contrast to the widely used method in Marcucci (1985). Future research would cover monitoring other types of multistage processes in service. An application of using probability trees to test and interpret associations in contingency tables is envisioned.Ph.D.Includes bibliographical references (p. 114-120)by Rodrigo Ignacio Duran Lope

    Cognitive Complexity of Comprehending Computer Programs

    Instructional designers must consider learners' learning trajectories and design tasks that are neither too hard nor too easy for them, sequencing tasks from less to more complex ones. Most efforts in programming assessment have been directed to code writing. However, programming is a multi-faceted skill, including precursory skills such as the comprehension of programs, which recent studies suggest having many interacting elements. An essential part of assessment is characterization of what makes a program unique and how to estimate learner's previous knowledge. When programs are different enough, instructors can intuitively compare the effort demanded of the learners. However, when the difference is subtle, instructors struggle to evaluate program's cognitive demands. Complexity is the metric used to describe the cognitive demands of a task. While research of computational and software engineering metrics of complexity are well-established, little research has been devoted to evaluating the complexity of comprehending programs from learners' perspective. In general, the taxonomies used by Computing Education to evaluate complexity do not evaluate the core content used in programming tasks. While subjective evaluations of difficulty proved to be useful in empirical evaluations, researchers have advocated for a complementary \emph{a priori} analytical metric of complexity to support instructional design. To alleviate such gaps, we seek to develop and present the necessary toolset to define and evaluate the cognitive complexity of comprehending computer programs. We introduce a novel conceptualization, the Rules of Program Behavior, which augment previous notional machine research and offer guidelines to communicate semantics instruction among practitioners and set the expectations of possible learners' mental models. We designed and partially validated a self-evaluation instrument to assess prior programming knowledge, inspired by frameworks successfully used in linguistics. These tools serve as input to our theoretical framework of cognitive complexity, which is based on educational psychology theories. The framework analyzes the cognitive elements present in a given program, and the way these elements are intertwined, extracting measurable aspects of complexity. Finally, we investigated instructors' perspectives of program comprehension and presented activities to foster program comprehension and how such activities could be sequenced to create learning trajectories. Our framework and tools laid the foundation to evaluate the cognitive complexity of program comprehension. We expect that the results of this thesis could support the design of assessment instruments, curricula, and programming languages. Our work particularly fits frameworks that holistically integrate skills and knowledge using authentic tasks while keeping learners' cognitive load in check. We believe that our results can be adapted to other aspects of programming and could help researchers to generate and test hypotheses related to program comprehension

    A mathematical programming approach to applicant selection for a degree program based on affirmative action

    In 2007, the Department of Industrial Engineering at the University of Chile allied with a major Chilean mining company to inaugurate a master's degree program in globalization management. The program's objective is to address the challenges Chile faces in its development of human and social capital by training young professionals. This paper describes the use of mathematical programming models in the program's applicant selection procedure for the first three entering classes, subject to equity criteria on gender, regional origin, and socioeconomic background. The models generated robust solutions in minutes, an achievement practically impossible using manual methods. The application's success demonstrates how mathematical programming and operations research can contribute to social policy.Fil: Duran, Guillermo Alfredo. Universidad de Buenos Aires.

    Orientador: Prof. Dr. Rodrigo Vasconcelos MachadoTese (doutorado) - Universidade Federal do Paraná, Setor de Ciências Humanas, Programa de Pós-Graduação em Letras. Defesa : Curitiba, 21/08/2019Inclui referências: p. 342-348Resumo: O objetivo geral desta tese é reunir e analisar a obra do poeta paranaense Rodrigo Júnior, pseudônimo de João Baptista Carvalho de Oliveira (1887-1964). Para isso, foi necessário coletar a quantidade máxima das suas publicações literárias e ensaísticas e, num recorte específico, analisá-las e discuti-las sob a perspectiva de quanto seus textos se apresentam como provincianos, e, quanto ao mesmo tempo não os são. Rodrigo Júnior é um autor que buscou intensamente seu próprio estilo no meio do confuso pré-modernismo, entre o parnasianismo, simbolismo e o neorromantismo, utilizando-se de várias estéticas e escolas unicamente com objetivo encontrar sua liberdade na arte. Nessa busca, encontrou a sua voz quando escreveu principalmente seus poemas com temas bucólicos, amorosos, satíricos, quase sempre atravessados por uma constante melancolia, por um tédio e pessimismo, uma tristeza de quem deseja paz e felicidade. Consagrou-se como poeta de rara qualidade, compondo ora em formas clássicas, ora em verso livre sempre com uma linguagem simples, mas também foi um eficiente prosador, como escritor de contos, crônicas, novelas e ensaios. Sua carreira começa no início do século XX e dura até os anos 60, atuando diariamente na imprensa curitibana, estabelecendo-se como um agitador cultural durante esse tempo. A produção gigantesca contrasta com seus poucos livros publicados, pois acabou abandonando muitos projetos de livros e deixando a maior parte dos seus escritos esparsos em jornais e revistas. Incentivou e influenciou pelo menos duas gerações de artistas do Paraná, como os jovens interessados no futurismo e no modernismo e os literatos da década de 30 e 40 que queriam modernizar as letras paranaenses. Por fim, dedicou boa parte da sua vida à literatura e à criação um sistema literário no Paraná autossuficiente que fosse independente dos grandes centros urbanos da época como o Rio de Janeiro. Palavras-chave: Rodrigo Júnior. Literatura paranaense. Pré-modernismo e modernismo paranaense. Simbolismo. Provincianismo.Abstract: The general objective of this thesis is to gather and analyze the work of the poet Rodrigo Júnior, pseudonym of João Baptista Carvalho de Oliveira (1887-1964). For this, it was necessary to collect the maximum amount of their literary and essayistic publications and, in a specific cut, to analyze and discuss them from the perspective of how much their texts are provincial, and at the same time not. Rodrigo Júnior is an author who intensely sought his own style in the midst of confusing pre-modernism, between parnasianism, symbolism and neorromantism, using various aesthetics and schools solely to find their freedom in art. In this search, he found his voice when he wrote mainly his poems with bucolic, loving, satirical themes, almost always crossed by a constant melancholy, boredom and pessimism, a sadness of those who want peace and happiness. He established himself as a poet of rare quality, composing sometimes in classical forms, sometimes in free verse always with simple language, but was also an efficient prospector, as a writer of short stories, chronicles, novels and essays. His career begins in the early twentieth century and lasts until the 1960s, working daily in the Curitiba press, establishing himself as a cultural agitator during that time. The mammoth production contrasts with its few published books, as it has abandoned many book projects and left most of its sparse writings in newspapers and magazines. It encouraged and influenced at least two generations of artists from Paraná, such as the young people interested in futurism and modernism and the literati of the 30's and 40's who wanted to modernize Paraná's lyrics. Finally, he devoted much of his life to literature and the creation of a self-sufficient literary system in Paraná that was independent of the great urban centers of the time such as Rio de Janeiro. Keywords: Rodrigo Júnior. Literature from Paraná. Premodernism and modernism of Paraná. Simbolism. Provincialism

    Delgado, Hegel and the Rodrigo Chronicles

    Richard Delgado has made path-breaking contributions to the literature on race and American law. His Rodrigo Chronicles are already classics of the Critical Race Theory genre. It is, therefore, wholly appropriate that the Harvard Latino Law Review dedicated a symposium issue to an examination of the Rodrigo Chronicles and Delgado\u27s other work. In this symposium essay, the author attempts to illuminate Delgado\u27s project in the Chronicles through an examination of various aspects of Hegel\u27s philosophy. Hegel\u27s philosophy allows us to better understand Delgado\u27s work in the Chronicles and elsewhere
