Bayesian inference networks, a synthesis of statistics and expert systems, have advanced reasoning under uncertainty in medicine, business, and social sciences. This innovative volume is the first comprehensive treatment exploring how they can be applied to design and analyze innovative educational assessments. Part I develops Bayes nets’ foundations in assessment, statistics, and graph theory, and works through the real-time updating algorithm. Part II addresses parametric forms for use with assessment, model-checking techniques, and estimation with the EM algorithm and Markov chain Monte Carlo (MCMC). A unique feature is the volume’s grounding in Evidence-Centered Design (ECD) framework for assessment design. This “design forward” approach enables designers to take full advantage of Bayes nets’ modularity and ability to model complex evidentiary relationships that arise from performance in interactive, technology-rich assessments such as simulations. Part III describes ECD, situates Bayes nets as an integral component of a principled design process, and illustrates the ideas with an in-depth look at the BioMass project: An interactive, standards-based, web-delivered demonstration assessment of science inquiry in genetics. This book is both a resource for professionals interested in assessment and advanced students. Its clear exposition, worked-through numerical examples, and demonstrations from real and didactic applications provide invaluable illustrations of how to use Bayes nets in educational assessment. Exercises follow each chapter, and the online companion site provides a glossary, data sets and problem setups, and links to computational resources.

Federal guidance on nutrition and diet is intended to reflect the state of the science and deliver the most reliable recommendations possible according to the best available evidence. This guidance, updated and presented every 5 years in the Dietary Guidelines for Americans (DGA), serves as the basis for all federal nutrition policies and nutrition assistance programs, as well as nutrition education programs. Despite the use of the guidelines over the past 30 years, recent challenges prompted Congress to question the process by which food and nutrition guidance is developed. This report assesses the process used to develop the guidelines; it does not evaluate the substance or use of the guidelines. As part of an overall, comprehensive review of the process to update the DGA, this first report seeks to discover how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints for the purpose of informing the 2020 cycle.

The College Instructor’s Guide to Writing Test Items: Measuring Student Learning addresses the need for direct and clear guidance on item writing for assessing broad ranges of content in many fields. By focusing on multiple-choice response items, this book provides college instructors the tools to understand, develop, and use assessment activities in classrooms in a way that consistently supports learning. Including dozens of example items and additional resources to support the item development process, this volume is unique in its practical-focus, and is essential reading for instructors and soon-to-be educators, professional development specialists, and higher education researchers. As teaching, assessment, and learning are inherently intertwined, The College Instructor’s Guide to Writing Test Items both facilitates the development of instructors’ own practice and improves the learning outcomes and success of students.

In the US, there is a wide-ranging network of at least 370 food banks, and more than 60,000 hunger-relief organizations such as food pantries and meal programs. These groups provide billions of meals a year to people in need. And yet hunger still affects one in nine Americans. What are we doing wrong? In Reinventing Food Banks and Pantries, Katie Martin argues that if handing out more and more food was the answer, we would have solved the problem of hunger decades ago. Martin instead presents a new model for charitable food, one where success is measured not by pounds of food distributed but by lives changed. The key is to focus on the root causes of hunger. When we shift our attention to strategies that build empathy, equity, and political will, we can implement real solutions. Martin shares those solutions in a warm, engaging style, with simple steps that anyone working or volunteering at a food bank or pantry can take today. Some are short-term strategies to create a more dignified experience for food pantry clients: providing client choice, where individuals select their own food, or redesigning a waiting room with better seating and a designated greeter. Some are longer-term: increasing the supply of healthy food, offering job training programs, or connecting clients to other social services. And some are big picture: joining the fight for living wages and a stronger social safety net. These strategies are illustrated through inspiring success stories and backed up by scientific research. Throughout, readers will find a wealth of proven ideas to make their charitable food organizations more empathetic and more effective. As Martin writes, it takes more than food to end hunger. Picking up this insightful, lively book is a great first step.

Policymakers and program managers are continually seeking ways to improve accountability in achieving an entity's mission. A key factor in improving accountability in achieving an entity's mission is to implement an effective internal control system. An effective internal control system helps an entity adapt to shifting environments, evolving demands, changing risks, and new priorities. As programs change and entities strive to improve operational processes and implement new technology, management continually evaluates its internal control system so that it is effective and updated when necessary. Section 3512 (c) and (d) of Title 31 of the United States Code (commonly known as the Federal Managers' Financial Integrity Act (FMFIA)) requires the Comptroller General to issue standards for internal control in the federal government.

In what circumstances and on what basis, should those who transmit serious diseases to their sexual partners be criminalised? In this new book Matthew Weait uses English case law as the basis of a more general and critical analysis of the response of the criminal courts to those who have been convicted of transmitting HIV during sex. Examining cases and engaging with the socio-cultural dimensions of HIV/AIDS and sexuality, he provides readers with an important insight into the way in which the criminal courts construct the concepts of harm, risk, causation, blame and responsibility. Taking into account the socio-cultural issues surrounding HIV/AIDS and their interaction with the law, Weait has written an excellent book for postgraduate and undergraduate law and criminology students studying criminal law theory, the trial process, offences against the person, and the politics of criminalisation. The book will also be of interest to health professionals working in the field of HIV/AIDS genito-urinary medicine who want to understand the issues that may face their clients and patients.
