Book excerpt: Resumen: El presente trabajo presenta el diseño y desarrollo de una metodología para que los estudiantes de la Universidad Tecnológica de Pereira, puedan realizar el cálculo de la incertidumbre de medición con base a la norma GTC 51 "Guía para la expresión de incertidumbre en las mediciones", basada en normas internacionales que actualmente son utilizadas a nivel científico, industrial y legal. Con la finalidad de crearle a la comunidad educativa una cultura metrológica consciente, acerca de la expresión correcta de los resultados de las mediciones realizadas en los laboratorios de Física, puesto que el resultado de cualquier medición NO está completo, sino está acompañado por una declaración cuantitativa de la incertidumbre, lo cual permite valorar la confiabilidad en dicho resultado. Por las razones anteriores se exponen 2 procedimientos didácticos, que reúnen los lineamientos más importantes para la adecuada expresión de la incertidumbre de medición para medidas directas e indirectas, con el fin de facilitar el aprendizaje del cálculo de incertidumbre de medida en las prácticas de los laboratorios de Física. Para cumplir con el objetivo general de este trabajo se crearon nuevas guías y modificaron las existentes, procurando que su contenido sea técnicamente correcto, desde el punto de vista físico, matemático y metrológico, siguiendo las definiciones dadas en el Vocabulario Internacional de Metrología (VIM).

Book excerpt: Introducción: En este trabajo se presenta una metodología didáctica y organizada paso a paso para la enseñanza de la estimación de la incertidumbre en mediciones experimentales realizadas en el laboratorio de Física II de la Universidad Tecnológica de Pereira. Actualmente en el curso experimental de laboratorio de física II de la Universidad Tecnológica de Pereira, no se da la importancia requerida a la estimación del cálculo de incertidumbre de medida, tampoco se cuenta con una guía unificada en la cual se brinde una metodología didáctica dirigida a estudiantes y profesores que permita realizar una aproximación de la importancia de la metrología como ciencia de la medición. Existen organizaciones dedicadas a la metrología científica, estas se encargan de estudiar todo lo relacionado a las medidas como los patrones de referencia y la forma como se debe realizar y expresar la incertidumbre de medida en datos experimentales. Este trabajo se basa en la GUM (Guide to de Expresion of Uncertainly) realizada por la Oficina internacional de pesas y medidas BIPM (Bureau International des Poids et Mesures). El objetivo general es diseñar e implementar una metodología didáctica que permita a los estudiantes del Laboratorio de física II de la Universidad Tecnológica de Pereira, adquirir las competencias necesarias para realizar el cálculo de la incertidumbre de medición de sus datos experimentales, comprendiendo y reconociendo todos los aspectos involucrados en este tema. Para alcanzar este objetivo ha sido necesario la intervención, reajuste y diseño de nuevas guías de laboratorio que cuentan con el materia necesario y la teoría correspondiente a los temas metrológicos requeridos para el curso experimental de laboratorio de física II, siguiendo estrictamente las definiciones del Vocabulario Internacional de Metrología (VIM) y del Sistema Internacional de Unidades (SI)...

Available in PDF, EPUB and Kindle. Book excerpt: La incertidumbre es un valor de imprecisi?n estimado. En un ejemplo m?s mundano: si tengo que usar una regla com?n para medir, por ejemplo, el largo de una mesa, distintas mediciones sucesivas me dar?n valores ligeramente diferentes: algunos mil?metros m?s o menos. Entonces lo que hace el cient?fico para establecer la medida de la mesa es manipular las mediciones sucesivas con ayuda de la estad?stica. En este caso, sacar? un promedio de las mediciones, por un lado, y por el otro calcular? la incertidumbre o incerteza de ese promedio. El valor de la medida del largo de la mesa ser?, por ejemplo: "tres metros m?s / menos tres mil?metros". El primer valor (tres metros) es el promedio de las mediciones. El segundo valor (tres mil?metros) es la incertidumbre. Entonces la medici?n no da por resultado un n?mero sino un intervalo, Este y otros planteos encontrar? el lector en este breve pero sugestivo texto del afamado cient?fico.

Download or read book bookdown written by Yihui Xie and published by CRC Press. This book was released on 2016-12-12 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: bookdown: Authoring Books and Technical Documents with R Markdown presents a much easier way to write books and technical publications than traditional tools such as LaTeX and Word. The bookdown package inherits the simplicity of syntax and flexibility for data analysis from R Markdown, and extends R Markdown for technical writing, so that you can make better use of document elements such as figures, tables, equations, theorems, citations, and references. Similar to LaTeX, you can number and cross-reference these elements with bookdown. Your document can even include live examples so readers can interact with them while reading the book. The book can be rendered to multiple output formats, including LaTeX/PDF, HTML, EPUB, and Word, thus making it easy to put your documents online. The style and theme of these output formats can be customized. We used books and R primarily for examples in this book, but bookdown is not only for books or R. Most features introduced in this book also apply to other types of publications: journal papers, reports, dissertations, course handouts, study notes, and even novels. You do not have to use R, either. Other choices of computing languages include Python, C, C++, SQL, Bash, Stan, JavaScript, and so on, although R is best supported. You can also leave out computing, for example, to write a fiction. This book itself is an example of publishing with bookdown and R Markdown, and its source is fully available on GitHub.
Download or read book Hidden Hunger written by H.K. Biesalski and published by Karger Medical and Scientific Publishers. This book was released on 2016-05-24 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malnutrition caused by deficiencies of vitamins and minerals - also called hidden hunger - impairs both the intellectual and physical development of a child. Due to the absence of clinical symptoms and assessments, no intervention can be staged. The tragedy is that this, in turn, decreases the child’s chance to escape from poverty. This book looks at malnutrition in high-income countries, the nutrition transition and nutritional deficiencies in low-income countries, consequences of hidden hunger, and interventions to improve nutrition security. Written by leading experts in the field, it clearly stresses that national governments and international organizations must make malnutrition one of their top priorities in order to provide children with optimal conditions for a healthy future.

Download or read book Particle Image Velocimetry written by Ronald J. Adrian and published by Cambridge University Press. This book was released on 2011 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle image velocimetry, or PIV, refers to a class of methods used in experimental fluid mechanics to determine instantaneous fields of the vector velocity by measuring the displacements of numerous fine particles that accurately follow the motion of the fluid. Although the concept of measuring particle displacements is simple in essence, the factors that need to be addressed to design and implement PIV systems that achieve reliable, accurate, and fast measurements and to interpret the results are surprisingly numerous. The aim of this book is to analyze and explain them comprehensively.
Download or read book Assessing Correctional Rehabilitation written by Francis T. Cullen and published by Createspace Independent Pub. This book was released on 2012-07-17 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theme that has persisted throughout the history of American corrections is that efforts should be made to reform offenders. In particular, at the beginning of the 1900s, the rehabilitative ideal was enthusiastically trumpeted and helped to direct the renovation of the correctional system (e.g., implementation of indeterminate sentencing, parole, probation, a separate juvenile justice system). For the next seven decades, offender treatment reigned as the dominant correctional philosophy. Then, in the early 1970s, rehabilitation suffered a precipitous reversal of fortune. The larger disruptions in American society in this era prompted a general critique of the “state run” criminal justice system. Rehabilitation was blamed by liberals for allowing the state to act coercively against offenders, and was blamed by conservatives for allowing the state to act leniently toward offenders. In this context, the death knell of rehabilitation was seemingly sounded by Robert Martinson's (1974b) influential “nothing works” essay, which reported that few treatment programs reduced recidivism. This review of evaluation studies gave legitimacy to the antitreatment sentiments of the day; it ostensibly “proved” what everyone “already knew”: Rehabilitation did not work. In the subsequent quarter century, a growing revisionist movement has questioned Martinson's portrayal of the empirical status of the effectiveness of treatment interventions. Through painstaking literature reviews, these revisionist scholars have shown that many correctional treatment programs are effective in decreasing recidivism. More recently, they have undertaken more sophisticated quantitative syntheses of an increasing body of evaluation studies through a technique called “meta-analysis.” These meta-analyses reveal that across evaluation studies, the recidivism rate is, on average, 10 percentage points lower for the treatment group than for the control group. However, this research has also suggested that some correctional interventions have no effect on offender criminality (e.g., punishment-oriented programs), while others achieve substantial reductions in recidivism (i.e., approximately 25 percent). This variation in program success has led to a search for those “principles” that distinguish effective treatment interventions from ineffective ones. There is theoretical and empirical support for the conclusion that the rehabilitation programs that achieve the greatest reductions in recidivism use cognitive-behavioral treatments, target known predictors of crime for change, and intervene mainly with high-risk offenders. “Multisystemic treatment” is a concrete example of an effective program that largely conforms to these principles. In the time ahead, it would appear prudent that correctional policy and practice be “evidence based.” Knowledgeable about the extant research, policymakers would embrace the view that rehabilitation programs, informed by the principles of effective intervention, can “work” to reduce recidivism and thus can help foster public safety. By reaffirming rehabilitation, they would also be pursuing a policy that is consistent with public opinion research showing that Americans continue to believe that offender treatment should be an integral goal of the correctional system.

Download or read book Fear of Crime in the United States written by Jodi Lane and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fear of Crime in the United States: Causes, Consequences, and Contradictions examines the nature and extent of crime-related fear. The authors describe and evaluate key research findings in the specific areas of methodology; gender, age, race and ethnicity, and socioeconomic status; contextual predictors; and the consequences of fear of crime. They discuss the improvement of fear of crime measures over time; the consistent finding that women are more afraid of crime; the impact of age, race and ethnicity, and socioeconomic status on fear; and the importance of environmental factors (such as witnessing crime and perceptions of diversity, disorder, and decline) and indirect victimization (through acquaintances and the media) on fear. The book also describes the physical, psychological, behavioral, and social effects of fear of crime. In the end, the authors tie the findings together to suggest important policy and research implications from the wealth of available research. There is no other book of which I am aware that so masterfully reviews empirical studies on fear of crime during the past half century to show how the research has changed and will continue to evolve. As long as there is crime, there will be perceptions of risk and fear of victimization; and Lane et al. help one to sift through the research with conceptual precision to formulate the most scientifically valid conclusions about the phenomena. The book is a hedgehog view of the research but points the way to needed research on topics such as fear of terrorism and how social context shapes perceptions of crime. The book is must-reading for those involved in research on victimization or fear of crime. - Kenneth F. Ferraro, Distinguished Professor of Sociology and Director of the Center on Aging and the Life Course, Purdue University This book consolidates the literature on fear of crime in a way that is unprecedented and that lends much-needed coherence to the area.

Download or read book Biological Dosimetry written by W. G. Eisert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 1982, a small international symposium was held at the Gesellschaft fUr Strahlen- und Umweltforschung mbH (GSF) in Munich as a satellite meeting of the IX International Conference on Analytical Cytology. The symposium focussed on cytometric approaches to biological dosimetry, and was, to the best of our knowledge, the first meeting on this subject ever held. There was strong encouragement from the 75 attendees and from others to publish a proceedings of the symposium. Hence this book, containing 30 of the 36 presentations, has been assembled. Dosimetry, the accurate and systematic determination of doses, usually refers to grams of substance administered or rads of ionization or some such measure of exposure of a patient, a victim or an experimental system. The term also can be used to describe the quantity of an ultimate, active agent as delivered to the appropriate target material within a biological system. Thus, for mutagens, one can speak of DNA dosimetry, meaning the number of adducts produced in the DNA of target cells such as bone-mar row stem cells or spermatogonia.
Download or read book Community Justice written by John R. Hamilton Jr. and published by Routledge. This book was released on 2010-12-08 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Community Justice discusses concepts of community within the context of justice policy and programs, and addresses the important relationship between the criminal justice system and the community in the USA. Taking a bold stance in the criminal justice debate, this book argues that crime management is more effective through the use of informal (as opposed to formal) social control. It demonstrates how an increasing number of criminal justice elements are beginning to understand that the development of partnerships within the community that enhance informal social control will lead to a stabilization and possible a decline in crime, especially violent crime, and make communities more liveable. Borrowing from an eclectic toolbox of ideas and strategies - community organizing, environmental crime prevention, private-public partnerships, justice initiatives – Community Justice puts forward a new approach to establishing safe communities, and highlights the failure of the current American justice system in its lack of vision and misuse of resources. Providing detailed information about how community justice fits within each area of the criminal justice system, and including relevant case studies to exemplify this philosophy in action, this book is essential reading for undergraduate and postgraduate students of subjects such as criminology, law and sociology.
