We develop a mixed-frequency, tree-based, gradient-boosting model designed to assess the default risk of privately held firms in real time. The model uses data from publicly-traded companies to construct a probability of default (PD) function. This function integrates high-frequency, market-based, aggregate distress signals with low-frequency, firm-level financial ratios, and macroeconomic indicators. When provided with private firms' financial ratios, the model, which we name signal-knowledge transfer learning model (SKTL), transfers insights gained from 35 thousand publicly-traded firms to more than 4 million private-held ones and performs well as an ordinal measure of privately-held firms' default risk.

We must make judgments all the time when we can't be certain of the risks. Should we have that elective surgery? Trust the advice of our financial adviser? Take that new job we've been offered? How worried should we be about terrorist attacks? In this lively and groundbreaking book, pioneering researcher Dylan Evans introduces a newly discovered kind of intelligence for assessing risks, demonstrating how vital this risk intelligence is in our lives and how we can all raise our RQs in order to make better decisions every day. Evans has spearheaded the study of risk intelligence, devising a simple test to measure a person's RQ which when posted online sparked a storm of interest and was taken by tens of thousands of people. His research has revealed that risk intelligence is quite different from IQ, and that the vast majority of us have quite poor risk intelligence. However, he did find some people who have very high RQs. So what makes the difference? Introducing a wealth of fascinating research findings, Evans identifies a key set of common errors in our thinking that most of us fall victim to and that undermine our risk intelligence, such as "ambiguity aversion," overconfidence in our knowledge, the fallacy of mind reading, and our attraction to worst-case scenarios. We are also regularly led astray by the ways in which information is provided to us. Citing a wide range of real-life examples--from the brilliant risk assessment skills of horse race handicappers to the tragically flawed evaluations of risk that caused the financial crisis--Evans illustrates that sometimes our most trusted advisors, including the experts and analysts at the top of their disciplines, don't always give us the best advice when it comes to risk evaluation. Presenting his revolutionary test that allows readers to evaluate their own RQs, Evans introduces a number of simple techniques we can use to build our risk assessment powers and reports on the striking results he's seen in training people to develop their RQs. Both highly engaging and truly mind-changing, Risk Intelligence will fascinate all of those who are interested in how we can improve our thinking in order to enhance our lives.

Business objectives and methods in an organization change periodically. Their supporting Information Systems (ISs) change even more dynamically for various reasons: system upgrades, software patches, routine maintenance, and intentionally or unintentionally induced attacks. Unless regular, routine, and timely risk assessments are conducted, changes in IS risks may never be noticed. Risk assessments need to be performed more frequently and faster in order to discover potential threats and to determine the changes that must be made to corporate computing environments to address them. Furthermore, conducting risk assessments on organizational assets can be time consuming, burdensome, and misleading in many cases because of the dynamically changing security states of assets. In theory, each asset can change its security states from one of secure, mitigated, vulnerable, or compromised. However, the secure state is only temporary and imaginary; it may never exist. Therefore, it is more accurate to say that each asset changes its security state from mitigated, vulnerable, or compromised. If we can predict an asset's future security state based on its current security state, we would have a good indicator of risk for the organization's mission-critical assets. Similarly, if risk factors of each mission critical asset could be quantified in near real-time, a risk assessment could be valuable in informing organizational stakeholders of the level of risk of their mission critical assets, which would then aid in their risk mitigation decisions. Quantifying organizational IS risk factors could be meaningful to an organization because quantifying risk levels could prompt a solution space in mitigating risks. In this research, we introduce an effective risk assessment using hidden Markov models (HMMs) in order to predict future security states and to quantify dynamically changing organizational IS assets by exploring possible security states from an insider user's perspective. HMMs have been used in many scientific fields to predict future states based on current states. Using these models, organizational mission critical assets could be assessed for their risk levels in a near real-time basis to determine the future risk level of each dynamically changing asset due to internally or externally induced threats.

By avoiding risk, are you also avoiding your life's full potential? Join acclaimed neurosurgeon Dr. Ben Carson as he explores the life-changing power of taking the risk, even if you're afraid. In our risk-avoidant culture, we place a high premium on safety. We insure our vacations. We check crash tests on cars. We extend the warranties on our appliances. But by insulating ourselves from the unknown--the natural risks of life--we miss the great adventure of living our lives to their fullest potential. Dr. Ben Carson spent his childhood as an at-risk child on the streets of Detroit, and he took big risks in performing complex surgeries on the brain and the spinal cord. Now, offering inspiring personal examples, Dr. Carson invites us to embrace risk in our own lives. In Take the Risk, Dr. Carson examines our safety-at-all-costs culture and the meaning of risk and security in our lives. Take the Risk guides you through an extensive examination of risk, including: Risk-taking in history An assessment of the real costs and rewards of risk Learning how to assess and accept risks Understanding how risk reveals the purpose of your life From a man whose life dramatically portrays the connection between great risks and greater successes, the insights Dr. Carson shares in Take the Risk will help you dispel your fear of risk in order to dream big, aim high, move with confidence, and reap the rewards of wise risk-taking. Praise for Take the Risk: "Whether you are a world-renowned neurosurgeon, a CEO, or a teacher, this book applies to anyone who ever wondered about the difference between the pacesetters and those who struggle to keep up. It is the pacesetters who Take the Risk, and this book explains when and why to take risks to empower everyone to become a trailblazer rather than a mere spectator. For anyone who wants to rise above mediocrity, this book is a must-read." --Armstrong Williams, author and radio host, The Armstrong Williams Show

Decision-making tools are needed to support environmental management in an increasingly global economy. Addressing threats and identifying actions to mitigate those threats necessitates an understanding of the basic risk assessment paradigm and the tools of risk analysis to assess, interpret, and communicate risks. It also requires modification of the risk paradigm itself to incorporate a complex array of quantitative and qualitative information that shapes the unique political and ecological challenges of different countries and regions around the world. This book builds a foundation to characterize and assess a broad range of human and ecological stressors, and risk management approaches to address those stressors, using chemical risk assessment methods and multi-criteria decision analysis tools. Chapters discuss the current state-of-knowledge with regard to emerging stressors and risk management, focusing on the adequacy of available systematic, quantitative tools to guide vulnerability and threat assessments, evaluate the consequences of different events and responses, and support decision-making. This book opens a dialogue on aspects of risk assessment and decision analysis that apply to real-time (immediate) and deliberative (long-term) risk management processes.
