Interpreting Evidence

This book explains the correct logical approach to analysis of forensic scientific evidence. The focus is on general methods of analysis applicable to all forms of evidence. It starts by explaining the general principles and then applies them to issues in DNA and other important forms of scientific evidence as examples. Like the first edition, the book analyses real legal cases and judgments rather than hypothetical examples and shows how the problems perceived in those cases would have been solved by a correct logical approach. The book is written to be understood both by forensic scientists preparing their evidence and by lawyers and judges who have to deal with it. The analysis is tied back both to basic scientific principles and to the principles of the law of evidence. This book will also be essential reading for law students taking evidence or forensic science papers and science students studying the application of their scientific specialisation to forensic questions.

Evaluating the strength of epidemiologic evidence is inherently challenging, both for those new to the field and for experienced researchers. This book offers a strategy for assessing epidemiologic research findings, explicitly describing the goals and products of research

CRYSTAL—Alberta was established to research ways to improve students’ understanding and reasoning in science and mathematics. To accomplish this goal, faculty members in Education, Science, and Engineering, as well as school teachers joined forces to produce a resource bank of innovative and tested instructional materials that are transforming teaching in the K-12 classroom. Many of the instructional materials cross traditional disciplinary boundaries and explore contemporary topics such as global climate change and the spread of the West Nile virus. Combined with an emphasis on the use of visualizations, the instructional materials improve students’ engagement with science and mathematics. Participation in the CRYSTAL—Alberta project has changed the way I think about the connection between what I do as a researcher and what I do as a teacher: I have learned how to better translate scientific knowledge into language and activities appropriate for students, thereby transforming my own teaching. I also have learned to make better connections between what students are learning and what is happening in their lives and the world, thereby increasing students’ interest in the subject and enriching their learning experience.

Interpreting Complex Forensic DNA Evidence is a handy guide to recent advances—and emerging issues—in interpreting complex DNA evidence and profiles for use in criminal investigations. In certain cases, DNA cannot be connected to a specific biological material such as blood, semen or saliva. How or when the DNA was deposited may be an issue. The possibility of generating DNA profiles from touched objects, where there may not be a visible deposit, has expanded the scope and number of exhibits submitted for DNA analysis. With such advances, and increasing improvements in technological capabilities in testing samples, this means it is possible to detect ever smaller amounts of DNA. There are also many efforts underway to seek was to interpret DNA profiles that are sub-optimal—either relative to the amount required by the testing kit and, potentially, the quality of the obtained sample. Laboratories often use enhancements in order to obtain a readable DNA profile. The broad-reaching implications of improving DNA sensitivity have led to this next, emerging generation of more complex profiles. Examples partial profiles that do not faithfully reflect the proposed donor, or mixtures of partial DNA from multiple people. A complexity threshold has been proposed to limit interpretation of poor-quality data. Research is now addressing the interpretation of transfer of trace amounts of DNA. Complex issues are arising in trial that need to be reconciled as such complexity has added challenges to the interpretation of evidence and its introduction or dismissal in certain cases in the courts. Key Features: Addresses DNA transfer, from person-to-person as well as to objects Outlines each stage required to produce a DNA profile from an exhibit—including collection, handling, storage, and analysis Discusses ethics, subjectivity, and bias—including cognitive dissonance—as they relate specifically to complex DNA evidence Highlights current techniques and the latest advances in DNA analysis, including advances in familial DNA searches Interpreting Complex Forensic DNA Evidence provides tools to assist the criminal investigator, forensic expert, and legal professional when posed with a DNA result in a forensic report or testimony. The result—and any associated statistic—may not reveal any ambiguity, complexity, or the assumptions involved in deriving it. Questions from resolved criminal cases are posed, and the relevant forensic literature, provided for the reader to assess a DNA result and any associated statistic. Case studies throughout illustrate concepts and emphasize the need for conclusions in the forensic report that are supported by the data.

Intended for forensic scientists and students, this book provides the necessary statistical tools and methodology for introducing forensic glass evidence into the laboratory. It contains an introductory chapter on glass evidence procedures and analysis before covering topics such as classical approaches to handling glass evidence, the application of Bayesian statistics to forensic science, and the use of histograms. The authors present both the physical and chemical examinations performed on glass along with their interpretations. With free software available for downloading at the authors' web site, scientists can apply their own data and draw conclusions using the principles detailed in the text.

How can defendants be tried if they cannot understand the charges being raised against them? Can a witness testify if the judges and attorneys cannot understand what the witness is saying? Can a judge decide whether to convict or acquit if she or he cannot read the documentary evidence? The very viability of international criminal prosecution and adjudication hinges on the massive amounts of translation and interpreting that are required in order to run these lengthy, complex trials, and the procedures for handling the demands facing language services. This book explores the dynamic courtroom interactions in the International Criminal Tribunal for the Former Yugoslavia in which witnesses testify through an interpreter about translations, attorneys argue through an interpreter about translations and the interpreting, and judges adjudicate on the interpreted testimony and translated evidence.

Employing a wide range of examples from Uncle Tom's Cabin and Birth of a Nation to Zelig and Personal Best, Janet Staiger argues that a historical examination of spectators' responses to films can make a valuable contribution to the history, criticism, and philosophy of cultural products. She maintains that as artifacts, films do not contain immanent meanings, that differences among interpretations have historical bases, and that these variations are due to social, political, and economic conditions as well as the viewers' constructed images of themselves. After proposing a theory of reception study, the author demonstrates its application mainly through analyzing the varying responses of audiences to certain films at specific moments in history. Staiger gives special attention to how questions of class, gender, sexual preference, race, and ethnicity enter into film viewers' interpretations. Her analysis reflects recent developments in post-structuralism, cognitive psychology, psychoanalysis, and cultural studies, and includes a discussion of current reader-response models in literary and film studies as well as an alternative approach for thinking about historical readers and spectators.
