Miscarriages of Justice and the Role of the Expert Witness
This chapter examines the role of the expert witness and the ways in which it has been both informed and formed by the high-profile miscarriages of justice. The expert witness is alone in the courtroom in being able to give opinion evidence and is there to assist the court with elucidating and presenting information about a specialist subject which is outside the expertise of the jury. This anomalous role was developed during the eighteenth century and the ability to give an opinion remains the primary factor that separates the role of the expert witness from that of other witnesses in court. In addition to the issue of non-disclosure, the appeals into the Maguire Seven, Birmingham Six and Judith Ward all exposed the problem of bias in relation to the evidence given by the expert witnesses. The experts were accused of having lost their impartiality.</p
The reliability of the Greulich and Pyle Atlas when applied to a modern Scottish population
This study examines the reliability of age estimation utilizing the Greulich and Pyle atlas in relation to a modern Scottish population. A total of 406 left-hand/wrist radiographs (157 females and 249 males) were age-assessed using the Greulich and Pyle atlas. Analysis showed that there was a strong correlation between chronological age and estimated age (females R(2) = 0.939, males R(2) = 0.940). When age groups were broken down into year cohorts, the atlas over-aged females from birth until 13 years of age. The pattern for males showed that the atlas under-estimated age until 13 years of age after which point it consistently over-aged boys between 13 and 17 years of age. This study showed that the Greulich and Pyle atlas can be applied to a modern population but would recommend that any analysis takes into account the potential for over- and under-aging shown in this study
Age estimation from radiographic images of the knee
This study examines the reliability of age estimation utilizing the Pyle and Hoerr atlas in relation to a modern Scottish population. The knee radiographs of 442 individuals (168 females, 274 males) were age assessed using the Pyle and Hoerr atlas. Analysis showed that there was a strong correlation between chronological age and estimated age (females R2 = 0.968, males R2 = 0.952). For females, the atlas method was most accurate between the ages of 9 and 15 years of age with an underage of 2.27 months and an overage of 2.38 months. For males, the atlas consistently overestimated age from the age of 9 years to the age of 16 years from between 0.14 and 8.81 months. The standard deviation for females was 9.86 months and for males was 10.75 months. This study showed that the Pyle and Hoerr atlas can be applied to a modern population with small modifications.</p
Does Mirror Imaging a Radiograph Affect Reliability of Age Assessment Using the Greulich and Pyle Atlas?
Age estimation is routinely undertaken by comparing radiographs of the individual in question to published reference samples of individuals of known age. This study examines the reliability of age estimation utilizing the Greulich and Pyle atlas in relation to both left- and right-hand/wrist radiographs and explores whether reversing right-hand/wrist radiographs, so that they are in the same anatomical orientation as those images used in the atlas affects reliability. A total of 403 left-hand/wrist radiographs and 415 right-hand/wrist radiographs were age assessed using the Greulich and Pyle atlas. Analysis showed that there is no significant loss in reliability when radiographs of the right hand (women R(2) = 0.887 and men R(2) = 0.907) are utilized instead of the left (women R(2) = 0.939 and men R(2) = 0.940) or when they are assessed as mirror images to those printed in the reference atlas (reversed female left hand R(2) = 0.929 and reversed male left hand R(2) = 0.931)
Responsibilities and Obligations of the Expert Witness
The expert witness is expected to assist the court in fulfilling its duty to case management and to do so by complying with the directions made by the court and to inform the court of any significant failure in such an objective. The obligations can be linked very clearly to the requirements outlined in Criminal Procedure Rules in relation to the construction of the expert witness report and following the principles outlined above in the ‘record’ approach to disclosure. If a breach occurs in relation to disclosure, then it can result in a prosecution being halted or delayed, a conviction being quashed on appeal, adverse comment about the expert witness and professional embarrassment, which could include action against the expert witness by their professional body. Accreditation is a process whereby the competency, credibility or authority of an organisation or an individual is certified by an external body or agency against an accepted standard.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
