Improvised explosive devices (IEDs) are a type of unconventional explosive weapon that can be deployed in a variety of ways, and can cause loss of life, injury, and property damage in both military and civilian environments. Terrorists, violent extremists, and criminals often choose IEDs because the ingredients, components, and instructions required to make IEDs are highly accessible. In many cases, precursor chemicals enable this criminal use of IEDs because they are used in the manufacture of homemade explosives (HMEs), which are often used as a component of IEDs. Many precursor chemicals are frequently used in industrial manufacturing and may be available as commercial products for personal use. Guides for making HMEs and instructions for constructing IEDs are widely available and can be easily found on the internet. Other countries restrict access to precursor chemicals in an effort to reduce the opportunity for HMEs to be used in IEDs. Although IED attacks have been less frequent in the United States than in other countries, IEDs remain a persistent domestic threat. Restricting access to precursor chemicals might contribute to reducing the threat of IED attacks and in turn prevent potentially devastating bombings, save lives, and reduce financial impacts. Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Explosive Precursor Chemicals prioritizes precursor chemicals that can be used to make HMEs and analyzes the movement of those chemicals through United States commercial supply chains and identifies potential vulnerabilities. This report examines current United States and international regulation of the chemicals, and compares the economic, security, and other tradeoffs among potential control strategies.
Bangladesh’s vulnerability to the effects of climate change is well documented; the evidence on the direct relationship between climate change and health focusing on Bangladesh is less so. Global evidence suggests intensification of climate change will increase incidences and variations of infectious diseases. Climate Afflictions contributes to filling this important knowledge gap. It includes a systematic review of existing literature on the relationship between climate change and health, distinguishing between climate change and variability. It establishes the relationship between climate variability and infectious diseases and mental health using household-level data. It also documents changes in climate patterns in Bangladesh over the past 44 years using monthly meteorological data. Overall, the report finds a strong relationship between infectious diseases, mental health, and climate variability. Based on analyses of primary data, it concludes that the prevalence of vector-borne diseases is higher during the monsoon than dry seasons, while the opposite is true for waterborne illnesses. Meanwhile, rising humidity and mean temperature are positively associated with respiratory illnesses. In terms of mental health conditions, while temperature is negatively correlated to depression, anxiety among individuals is likely to increase with temperature and humidity. Irrespective of the season, morbidity and mental health issues are highest in densely populated urban hubs such as Dhaka and Chattogram compared to other areas. The mean temperature in Bangladesh has increased by 0.5°C between 1976 and 2019. Overall, summers are becoming hotter and longer, the monsoon season is extending, and winters are becoming warmer. Consequently, Bangladesh is on the path to losing its distinct seasonality. With global warming progressing faster than initially projected, stresses on human health may be elevated to an extent that can overburden the systems to a point at which adaptation will no longer be possible. Countries susceptible to climate change, like Bangladesh, need to be better prepared.

Engineering skills and knowledge are foundational to technological innovation and development that drive long-term economic growth and help solve societal challenges. Therefore, to ensure national competitiveness and quality of life it is important to understand and to continuously adapt and improve the educational and career pathways of engineers in the United States. To gather this understanding it is necessary to study the people with the engineering skills and knowledge as well as the evolving system of institutions, policies, markets, people, and other resources that together prepare, deploy, and replenish the nation's engineering workforce. This report explores the characteristics and career choices of engineering graduates, particularly those with a BS or MS degree, who constitute the vast majority of degreed engineers, as well as the characteristics of those with non-engineering degrees who are employed as engineers in the United States. It provides insight into their educational and career pathways and related decision making, the forces that influence their decisions, and the implications for major elements of engineering education-to-workforce pathways.
Good requirements do not come from a tool, or from a customer interview. They come from a repeatable set of processes that take a project from the early idea stage through to the creation of an agreed-upon project and product scope between the customer and the developer.From enterprise analysis and planning requirements gathering to documentation,
The Model Rules of Professional Conduct provides an up-to-date resource for information on legal ethics. Federal, state and local courts in all jurisdictions look to the Rules for guidance in solving lawyer malpractice cases, disciplinary actions, disqualification issues, sanctions questions and much more. In this volume, black-letter Rules of Professional Conduct are followed by numbered Comments that explain each Rule's purpose and provide suggestions for its practical application. The Rules will help you identify proper conduct in a variety of given situations, review those instances where discretionary action is possible, and define the nature of the relationship between you and your clients, colleagues and the courts.
In light of growing discourse on 'frugal innovation', this book offers novel approaches to innovation based on extensive empirical research. The study complements a decade of scholarly attention on frugal innovation by taking a research-based approach to innovation in resource-scarce and complex institutional contexts. The findings suggest that concepts such as frugal, reverse, jugaad, social, grassroots and inclusive innovation in fact represent heterogeneous assemblies of innovation for social, environmental and economic value. The conceptual framework invites attention to more plural sources and elements in the study of models of innovation to inspire further research in the fields of strategy, innovation, entrepreneurship, economic sociology and development studies. The design framework offers models, metrics and competencies for practitioners and policymakers to identify, evaluate and design frugal innovations. The comprehensive view of frugal innovation demonstrates how firms can implement globally competitive strategies by pursuing innovation for humanity to improve lives for everyone, everywhere.
