Practical and comprehensive, this is the first book to focus on noncredible performance in clinical contexts. Experts in the field discuss the varied causes of invalidity, describe how to efficiently ...incorporate validity tests into clinical evaluations, and provide direction on how to proceed when noncredible responding is detected. Thoughtful, ethical guidance is given for offering patient feedback and writing effective reports. Population-specific chapters cover validity assessment with military personnel; children; and individuals with dementia, psychiatric disorders, mild traumatic brain injury, academic disability, and other concerns. The concluding chapter describes how to appropriately engage in legal proceedings if a clinical case becomes forensic. Case examples and sample reports enhance the book's utility.
The steel industry is one the biggest consumers of refractories. In this industry, refractories are commonly used as linings for steel production equipment, because they can sustain high temperature ...and corrosive attack in their working environment. However due to the harsh conditions, their life span is limited. Corrosion mainly by slag and molten steel is the principal phenomenon responsible for degradation and wear of the refractory bricks. It is a complex phenomenon that is due to infiltration (penetration) into and subsequent dissolution of the refractories by slags and molten steel. A thorough understanding of these mechanisms is necessary in order to improve the refractories behavior for steel making applications. However, even nowadays, no laboratory test can reproduce the real working conditions in the steel industry. According to the parameter of interest several testing methods have been developed. They can be static like the sessile drop test or crucible test or dynamic like the rotary slag test. This paper describes the principal corrosion tests used in the steel industry in order to give an overview of the way to determine and finally alleviate the impact of corrosion on refractories.

Just as comprehension strategies have helped millions of students learn to read like proficient readers, they can also help students think like effective test-takers. The authors show how students ...can use background knowledge, mental images, synthesizing, monitoring, inferring, questioning, and determining of importance to understand the genre of tests and to think through the problems they are given. Instead of engaging in artificial and disconnected activities to cram for upcoming tests, students learn skills and strategies that will serve them throughout their school careers and beyond. Presenting numerous classroom vignettes featuring students in grades 3-8, "Put Thinking to the Test" includes: (1) examples of the direct application of thinking strategy instruction to test taking; (2) actual work samples from lessons used with students; (3) additional lesson ideas that go beyond the teaching described in the vignettes; (4) detailed anchor charts; and (5) background on how the authors came to understand this work so that a staff, team, or individual teacher can apply these concepts in their own school setting. This book is divided into three sections. Section I, Wondering About Tests, contains the following chapters: (1) Coming to Know Standardized Tests: Walking in Our Students' Shoes; (2) Tests as a Genre: What Makes Standardized Tests Unique; and (3) Increasing Student Stamina: The Role of Workshop Structures in Becoming Successful Test Takers. Section II, Thinking About Tests, contains the following chapters: (4) Ask Questions; (5) Create Mental Images; (6) Draw Inferences; (7) Synthesize New Learning and Ideas; (8) Activate, Utilize, and Build Background Knowledge (Schema); (9) Determine the Most Important Ideas and Themes; and (10) Monitor for Meaning and Problem-Solve When Meaning Breaks Down. Section III, Still Learning About Tests, contains the following chapters: (11) Q and A--Weaving Thinking Together with Testing; and (12) Integrity: It's All About Being True to Ourselves and Our Profession. References are also included. Foreword by Ellin Keene.
This book was proposed and organized as a means to present recent developments in the field of testing of materials and elements in civil engineering. For this reason, the articles highlighted in ...this editorial relate to different aspects of testing of different materials and elements in civil engineering, from building materials to building structures. The current trend in the development of testing of materials and elements in civil engineering is mainly concerned with the detection of flaws and defects in concrete elements and structures, and acoustic methods predominate in this field. As in medicine, the trend is towards designing test equipment that allows one to obtain a picture of the inside of the tested element and materials. Interesting results with significance for building practices were obtained.

Numerical data that are normally distributed can be analyzed with parametric tests, that is, tests which are based on the parameters that define a normal distribution curve. If the distribution is ...uncertain, the data can be plotted as a normal probability plot and visually inspected, or tested for normality using one of a number of goodness of fit tests, such as the Kolmogorov-Smirnov test. The widely used Student's t-test has three variants. The one-sample t-test is used to assess if a sample mean (as an estimate of the population mean) differs significantly from a given population mean. The means of two independent samples may be compared for a statistically significant difference by the unpaired or independent samples t-test. If the data sets are related in some way, their means may be compared by the paired or dependent samples t-test. The t-test should not be used to compare the means of more than two groups. Although it is possible to compare groups in pairs, when there are more than two groups, this will increase the probability of a Type I error. The one-way analysis of variance (ANOVA) is employed to compare the means of three or more independent data sets that are normally distributed. Multiple measurements from the same set of subjects cannot be treated as separate, unrelated data sets. Comparison of means in such a situation requires repeated measures ANOVA. It is to be noted that while a multiple group comparison test such as ANOVA can point to a significant difference, it does not identify exactly between which two groups the difference lies. To do this, multiple group comparison needs to be followed up by an appropriate post hoc test. An example is the Tukey's honestly significant difference test following ANOVA. If the assumptions for parametric tests are not met, there are nonparametric alternatives for comparing data sets. These include Mann-Whitney U-test as the nonparametric counterpart of the unpaired Student's t-test, Wilcoxon signed-rank test as the counterpart of the paired Student's t-test, Kruskal-Wallis test as the nonparametric equivalent of ANOVA and the Friedman's test as the counterpart of repeated measures ANOVA.

The second edition of the International Test Commission Guidelines for Translating and Adapting Tests was prepared between 2005 and 2015 to improve upon the first edition, and to respond to advances ...in testing technology and practices. The 18 guidelines are organized into six categories to facilitate their use: pre-condition (3), test development (5), confirmation (4), administration (2), scoring and interpretation (2), and documentation (2). For each guideline, an explanation is provided along with suggestions for practice. A checklist is provided to improve the implementation of the guidelines. This paper was written by the International Test Commission (ITC), including Dave Bartram, Giray Berberoglu, Jacques Grégoire, Ronald Hambleton, Jose Muniz, and Fons van de Vijver.
