Evaluation in Today’s World : Respecting Diversity, Improving Quality, and Promoting Usability
Recipient of a 2021 Most Promising New Textbook Award from the Textbook & Academic Authors Association (TAA) Evaluation in Today’s World: Respecting Diversity, Improving Quality, and Promoting Usability is a timely and comprehensive textbook that guides students, practitioners, and users of evaluations in understanding evaluation purposes, theories, methodologies, and challenges within today’s sociocultural and political context.Veronica G. Thomas and Patricia B. Campbell include discussions of evaluation history, frameworks, models, types, planning, and methods, through a social justice, diversity, and inclusive lens.The authors focus on ethics in diverse cultural contexts, help readers understand how social problems and programs get politicized and, sometimes, framed through a racialized lens, show how to engage stakeholders in the evaluation process, and communicate results in culturally appropriate ways. Included with this title: The password-protected Instructor Resource Site (formally known as SAGE Edge) offers access to all text-specific resources, including a test bank and editable, chapter-specific PowerPoint® slides.

Introduction To Analysis With Complex Numbers
This is a self-contained book that covers the standard topics in introductory analysis and that in addition constructs the natural, rational, real and complex numbers, and also handles complex-valued functions, sequences, and series. The book teaches how to write proofs. Fundamental proof-writing logic is covered in Chapter 1 and is repeated and enhanced in two appendices.Many examples of proofs appear with words in a different font for what should be going on in the proof writer's head. The book contains many examples and exercises to solidify the understanding.The material is presented rigorously with proofs and with many worked-out examples.Exercises are varied, many involve proofs, and some provide additional learning materials.

Usability Testing of Medical Devices
Usability Testing of Medical Devices covers the nitty-gritty of usability test planning, conducting, and results reporting.The book also discusses the government regulations and industry standards that motivate many medical device manufacturers to conduct usability tests. Since publication of the first edition, the FDA and other regulatory groups have modified their regulations and expectations regarding how medical device manufacturers should approach usability testing.Reflecting these changes, this Second Edition provides updated guidance to readers with an interest or direct role in conducting a usability test of a medical device or system.Key updates involve the 2011 FDA guidance on human factors engineering, requirements set forth by the third edition of IEC 60601 and closely related IEC 62366-1:2015, linking usability test tasks to risk analysis results, and analyzing root causes of use errors that occur during usability tests.Written by seasoned human factors specialists, Usability Testing of Medical Devices, Second Edition is an informative, practical, and up-to-date handbook for conducting usability tests of medical devices.The book helps ensure a smooth and painless development process—and thus, safe and effective medical devices.

Numbers, Numbers Everywhere
An original concept where math is explained on real life situations showing the practical usage of numbers in our everyday lives. Math is usually considered a demanding, boring or even a scary subject.But numbers are all around us and we use them and math constantly without even realizing it.Various usage of numbers in different environments is presented in 17 chapters and the book ends with a double-spread where kids can try out their newly gained knowledge. The aim of this book is to show math as a fun and useful subject that can be comprehensible and that helps us in many ways on a daily basis.

What is the algorithm for testing prime numbers?
The algorithm for testing prime numbers involves checking if the number is divisible by any integer from 2 to the square root of the number. If the number is divisible by any of these integers, then it is not a prime number. If the number is not divisible by any of these integers, then it is a prime number. This algorithm is efficient because it only needs to check up to the square root of the number, reducing the number of iterations needed to determine if a number is prime.

What are integers, rational numbers, natural numbers, real numbers, and irrational numbers?
Integers are whole numbers, including both positive and negative numbers, as well as zero. Rational numbers are numbers that can be expressed as a fraction of two integers, where the denominator is not zero. Natural numbers are the counting numbers, starting from 1 and going up to infinity. Real numbers include all rational and irrational numbers, and they can be represented on the number line. Irrational numbers are numbers that cannot be expressed as a fraction and have non-repeating, non-terminating decimal representations.
-
Are negative numbers irrational numbers?
No, negative numbers are not irrational numbers. Irrational numbers are numbers that cannot be expressed as a fraction of two integers, and they have non-repeating, non-terminating decimal representations. Negative numbers, on the other hand, can be expressed as a fraction of two integers and have terminating decimal representations. Therefore, negative numbers are not considered irrational numbers.
-
Are negative numbers real numbers?
Yes, negative numbers are real numbers. Real numbers include all rational and irrational numbers, which encompass positive, negative, and zero values. Negative numbers are simply numbers that are less than zero on the number line and are an essential part of the real number system.

Are whole numbers also decimal numbers?
No, whole numbers are not considered decimal numbers. Whole numbers are integers that do not have any fractional or decimal parts, while decimal numbers include a decimal point and can have fractional parts. For example, the whole number 5 is not a decimal number, but the decimal number 5.0 includes a decimal point and is considered a decimal number.

How can one present the proof for complex numbers in analysis?
One can present the proof for complex numbers in analysis by starting with the definition of complex numbers as ordered pairs of real numbers, and then introducing the operations of addition and multiplication for complex numbers. The proof can then proceed to show that these operations satisfy the properties of a field, such as closure, associativity, commutativity, and distributivity. Additionally, one can demonstrate the existence of additive and multiplicative inverses for complex numbers, as well as the existence of a multiplicative identity. Finally, the proof can conclude by showing that the set of complex numbers forms a field, and therefore can be treated as a complete algebraic system.

What are real numbers and imaginary numbers?
Real numbers are numbers that can be found on the number line, including integers, fractions, and irrational numbers like pi and the square root of 2. Imaginary numbers, on the other hand, are numbers that involve the square root of -1, denoted as 'i'. When a real number is multiplied by 'i', it becomes an imaginary number. Together, real and imaginary numbers make up the set of complex numbers.

Why are round numbers called round numbers?
Round numbers are called "round" because they are easy to work with and understand. They are multiples of 10, which makes them easy to divide, multiply, and round off. Their simplicity and ease of use make them "round" in the sense that they are smooth and convenient for calculations and estimations. This term has been used for centuries to describe numbers that are easily manageable and divisible.
