Chemicals are everywhere. Many are natural and safe, others synthetic and dangerous. Or is it the other way around? Walking through the supermarket, you might ask yourself: Should I be eating organic food? Is that anti-wrinkle cream a gimmick? Is it worth buying BPA-free plastics? This new edition of Chemistry in the Marketplace provides fresh explanations, fascinating facts and funny anecdotes about the serious science in the products we buy and the resources we use. It might even save you some money. With chapters on the chemistry found in different parts of our home, in the backyard and in the world around us, Ben Selinger and Russell Barrow explain how things work, where marketing can be deceptive and what risks you should really be concerned about. Chemistry in the Marketplace is a valuable resource for university lecturers, high school teachers and students of chemistry and chemistry related subjects and disciplines, such as biochemistry, microbiology and science in society.

Intensely readable, poetic, truthful, wise and wonderful.' STEPHEN FRY 'An extraordinary book.' SUNDAY TIMES Struggling to comprehend the shocking death of his teenage daughter, Ben Goldsmith finds solace in nature by immersing himself in plans to rewild his farm. In July 2019, Ben Goldsmith lost his fifteen-year-old daughter, Iris, in an accident on their family farm in Somerset. Iris's death left her family reeling. Grasping for answers, Ben threw himself into searching for some ongoing trace of his beloved child, exploring ideas that until then had seemed too abstract to mean much to him. Missing his daughter terribly and struggling to imagine how he would face the rest of his life in the shadow of this loss, Ben found solace in nature, the object of a lifelong fascination. As Ben set about rewilding his farm, nature became a vital source of meaning and hope. This book is the story of a year of soul-searching that followed a terrible loss. In an instant, Ben's world had turned dark. Yet, unbelievably to him, the seasons kept on turning, and as he immersed himself in the dramatic restoration of nature in the place where it happened, he found healing. In God is an Octopus, Ben tells a powerful, immersive and inspiring story of finding comfort and strength in nature after suffering loss and despair.
Have you ever wondered why students too often have only a rudimentary understanding of mathematics, why even rich and exciting hands-on learning does not always result in "real" learning of new concepts? The answer lies in whether students have actually learned mathematical concepts, rather than merely memorizing facts and formulas. Concept-Rich Mathematics Instruction is based on the constructivist view that concepts are not simply facts to be memorized and later recalled, but rather knowledge that learners develop through an active process of adapting to new experiences. The teacher's role is critical in this process. When teachers prompt students to reflect on their experiences and report and answer questions verbally, students must re-examine and even revise their concepts of reality. Meir Ben-Hur offers expert guidance on all aspects of Concept-Rich Mathematics Instruction, including * Identifying the core concepts of the mathematics curriculum. * Planning instructional sequences that build upon concepts that students already understand. * Designing learning experiences that provoke thoughtful discussions about new concepts and prepare students to apply these concepts on their own. * Identifying student errors, particularly those caused by preconceptions, as important sources of information and as key instructional tools. * Conducting classroom dialogues that are rich in alternative representations. * Using a variety of formative assessment methods to reveal the state of students' learning. * Incorporating problem-solving activities that provoke cognitive dissonance and enhance students' cognitive competence. Concept-Rich Mathematics Instruction is grounded in the belief that all students can learn to think mathematically and solve challenging problems. If you're looking for a powerful way to improve students' performance in mathematics and move closer to fulfilling the NCTM standards, look no further: this approach provides the building blocks for constructing a first-class mathematics program. Note: This product listing is for the reflowable (ePub) version of the book.
This latest edition of Case Critical applies decolonized, critical analysis to highlight what is often hidden from view for most Canadians: the personal trauma and communal devastation inflicted on Indigenous people by past and present colonialism and the ways in which neoliberal tax cuts, austerity, and privatization create more inequality, homelessness, and despair among both Indigenous and non-Indigenous people. Social service providers, the authors argue, should become social activists, working in solidarity with progressive grassroots social movements in order to de-legitimatize colonial and neoliberal policies.

This book is about database security and auditing. You will learn many methods and techniques that will be helpful in securing, monitoring and auditing database environments. It covers diverse topics that include all aspects of database security and auditing - including network security for databases, authentication and authorization issues, links and replication, database Trojans, etc. You will also learn of vulnerabilities and attacks that exist within various database environments or that have been used to attack databases (and that have since been fixed). These will often be explained to an "internals level. There are many sections which outline the "anatomy of an attack – before delving into the details of how to combat such an attack. Equally important, you will learn about the database auditing landscape – both from a business and regulatory requirements perspective as well as from a technical implementation perspective.* Useful to the database administrator and/or security administrator - regardless of the precise database vendor (or vendors) that you are using within your organization.* Has a large number of examples - examples that pertain to Oracle, SQL Server, DB2, Sybase and even MySQL.. * Many of the techniques you will see in this book will never be described in a manual or a book that is devoted to a certain database product.* Addressing complex issues must take into account more than just the database and focusing on capabilities that are provided only by the database vendor is not always enough. This book offers a broader view of the database environment - which is not dependent on the database platform - a view that is important to ensure good database security.
This invaluable reference book explains the chemistry we encounter in our daily life in terms that everyone can understand. Makes chemistry come alive and is illustrated with fascinating anecdotes, interesting snippets of information and experiments which further clarify the topics.
In Replacement Parts, internationally recognized bioethicist Arthur L. Caplan and coeditors James J. McCartney and Daniel P. Reid assemble seminal writings from medicine, philosophy, economics, and religion that address the ethical challenges raised by organ transplantation. Caplan's new lead essay explains the shortfalls of present policies. From there, book sections take an interdisciplinary approach to fundamental issues like the determination of death and the dead donor rule; the divisive case of using anencephalic infants as organ donors; the sale of cadaveric or live organs; possible strategies for increasing the number of available organs, including market solutions and the idea of presumed consent; and questions surrounding transplant tourism and "gaming the system" by using the media to gain access to organs. Timely and balanced, Replacement Parts is a first-of-its-kind collection aimed at surgeons, physicians, nurses, and other professionals involved in this essential lifesaving activity that is often fraught with ethical controversy.
