  • Business financial decisions are not made in a vacuum. An ‘obvious’ decision may often have to be tempered by an appreciation of the restrictions imposed by the prevailing environment. Although it is beyond our scope to consider the full social, political and economic complexity of the financial decision-making context, we provide an overview of the key features of the UK financial and economic system. A sound grasp of the framework for financial decisions is essential if the reader is to appreciate fully the issues discussed in subsequent chapters of this book....

  • hess is a game of decisions. As well as deciding about which move to play and which plan to adopt, players must also make practical decisions about how to use their clock time and whether to use intuition rather than trying to calculate every line to a finish. Viacheslav Eingorn draws upon his vast experience to provide guidance on how to weigh the various factors in positions and decide on the best course of action. He examines many practical examples and explains how the critical decisions were made, and investigates whether they were correct. By following Eingorn on this voyage...

  • Harrison's Internal Medicine Chapter 3. Decision-Making in Clinical Medicine Decision-Making in Clinical Medicine: Introduction To the medical student who requires 2 h to collect a patient's history and perform a physical examination, and several additional hours to organize them into a coherent presentation, the experienced clinician's ability to reach a diagnosis and decide on a management plan in a fraction of the time seems extraordinary.

  • In an increasingly complex world, decision analysis has a major role to play in helping decision makers to gain a greater understanding of the problems they face. The main aim of this book is to make decision analysis accessible to its largest group of potential users: managers and administrators in business and public sector organizations, most of whom, although expert at their work, are not mathematicians or statisticians.

  • Risk has become one of the main topics in fields as diverse as engineering, medicine, and economics, and it is also studied by social scientists, psychologists, and legal scholars. But the topic of risk also leads to more fundamental questions such as:What is risk?What can decision theory contribute to the analysis of risk? What does the human perception of risk mean for society? How should we judge whether a risk is morally acceptable or not? Over the last couple of decades, questions like these have attracted interest from philosophers and other scholars into risk theory.

  • This book has been made possible by a sea of efforts. Collating this book was a labour of love. I share the topic of Decision-making support systems with the reader with a sense of zeal and oceans of enthusiasm. I think that these attributes are reflected in this book and perhaps make it better. I wish to thank Sophie Tergeist from Bookboon Ltd for her guidance and Shafaqat Hussain for designing the cover of this book. Each chapter in this book was subject to a previous peer-review process.

  • Major Influences on Clinical Decision-Making More than a decade of research on variations in clinician practice patterns has shed much light on forces that shape clinical decisions. The use of heuristic "shortcuts," as detailed above, provides a partial explanation, but several other key factors play an important role in shaping diagnostic hypotheses and management decisions.

  • Clinical Practice Guidelines According to the 1990 Institute of Medicine definition, clinical practice guidelines are "systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances." This definition provides emphasis to several crucial features of modern guideline development. First, guidelines are created using the tools of EBM. In particular, the core of the development process is a systematic literature search followed by a review of the relevant peer-reviewed literature.

  • Calculating sensitivity and specificity requires selection of a decision value for the test to define the threshold value at or above which the test is considered "positive." For any given test, as this cut point is moved to improve sensitivity, specificity typically falls and vice versa. This dynamic tradeoff between more accurate identification of subjects with disease versus those without disease is often displayed graphically as a receiver operating characteristic (ROC) curve (Fig. 3-1). An ROC curve plots sensitivity (y-axis) versus 1 – specificity (x-axis).

  • This paper describes novel and practical Japanese parsers that uses decision trees. First, we construct a single decision tree to estimate modification probabilities; how one phrase tends to modify another. Next, we introduce a boosting algorithm in which several decision trees are constructed and then combined for probability estimation. The two constructed parsers are evaluated by using the EDR Japanese annotated corpus. The single-tree method outperforms the conventional .Japanese stochastic methods by 4%. ...

  • Making decisions under conditions of risk and uncertainty is one of the most important activities that managers engage in. Generally, there is a lack of information and a limited amount of time available to make the decision. Procrastinating and not making a decision sometimes has greater risk than making it.

  • This paper discusses a decision-tree approach to the problem of assigning probabilities to words following a given text. In contrast with previous decision-tree language model attempts, an algorithm for selecting nearly optimal questions is considered. The model is to be tested on a standard task, The Wall Street Journal, allowing a fair comparison with the well-known trigram model.

  • In the face of sparsity, statistical models are often interpolated with lower order (backoff) models, particularly in Language Modeling. In this paper, we argue that there is a relation between the higher order and the backoff model that must be satisfied in order for the interpolation to be effective. We show that in n-gram models, the relation is trivially held, but in models that allow arbitrary clustering of context (such as decision tree models), this relation is generally not satisfied. ...
