  • A theory of caricature is used to analyse and explain the nature of—and reactions to—a controversial political cartoon depicting Jacob Zuma, the highly publicized president of South Africa, and how the cartoon both played on and affected his political image and brand. Jacob Zuma has crafted his image as a person who has overcome insurmountable injustices to lead his nation. The cartoon directly questioned Zuma's claims of discrimination by the justice system. The cartoonist (Zapiro) was able to use the cartoon to further solidify Zuma's image as an embattled yet contentious and divisive leader. The framework that follows depicts the spoofing of a political brand, in a marketing environment in which parody and spoofing of more conventional products and services are increasingly common.

There is a serious issue within the forensic science community, which even extends outside of the field. The role of the scientist in the investigation of crime has been increasingly confined to the laboratory, which has been accompanied by the conflation of the terms forensic science and criminalistics. This unfortunate situation has been festering for years. To make matters worse, the era of the proactive, problem-defining, criminalist (generalist) is waning, and possibly over. Present-day “criminalists” are treated as little more than reactive, protocol-constrained, laboratory technicians, with few, if any, consequential crime scene roles. In most cases, these “criminalists” merely respond to routine requests from prosecutors and police. The absence of science at the front end of forensic investigations, i.e., the scene, has resulted in biased, ineffective, inefficient, and/or erroneous outcomes with immediate and long-term societal impacts. To disentangle this imbroglio, we propose the use of another term, traceology, which has seen limited use worldwide except in the field of archaeology. With respect to criminalistics, this term has been previously proposed by Margot (20–21). Traceology is an historical science, dealing with the examination, analysis, and scientific interpretation of event traces (signs or remnants) of earlier activities. In this commentary, we define and redefine familiar, but ambiguous, terms and concepts with the hope of recapturing the essence of criminalistics (32), which we suggest is best termed traceology.  相似文献

Abstract: Accuracy of forensic facial approximation and superimposition techniques relies on the knowledge of anatomical correlations between soft and hard tissues. Recent studies by Stephan and collaborators (6,8,10) reviewed traditional guidelines leading to a wrong placement of the eyeball in the orbit. As those statements are based on a small cadaver sample, we propose a validation of these findings on a large database (n = 375) of living people. Computed tomography scans of known age and sex subjects were used to collect landmarks on three‐dimensional surfaces and DICOM with TIVMI. Results confirmed a more superior and lateral position of the eyeball relatively to the orbital rims. Orbital height and breadth were used to compute regression formulae and proportional placement using percentages to find the most probable position of the eyeball in the orbit. A size‐related sexual dimorphism was present but did not impact on the prediction accuracy.  相似文献

Digital investigation of anthropological material through computed tomography (CT) offers several new opportunities in morphometrics. However, an object measured with computer-assisted methods does not necessarily exactly match the original one. The scanning and surface reconstruction of the object induce some alterations, and data acquisition is prone to measurement uncertainty. The purpose of this research is to evaluate the intra- and inter-observers variations in medical CT scan measurements of a known-size phantom and two dry crania. Two software packages, AMIRA and Treatment and Increased Vision for Medical Imaging (TIVMI), which use different techniques of surface reconstructions, were compared. The mean difference between the measurements was lower for TIVMI, using an objective algorithm based on the half-maximum height (HMH) protocol in three dimensions (3D). AMIRA can induce up to a 4% error in known measurements and 5% uncertainty in dry skull measurements. This study emphasises the risk of object shape alteration in each step of its digitisation.  相似文献

This paper proposes an alternative solution to multimetal deposition (MMD) for the development of latent fingermarks on non-porous and porous surfaces. MMD offers a good sensitivity, however it is very time-consuming and requires many reagents to be carried out. Single-metal deposition (SMD) replaces the silver enhancement of the gold colloids by a gold enhancement procedure. This reduces the number of baths by one as well as the number of reagents and their cost, utilizes reagents with a longer shelf life, and most importantly reduces the labor-intensity of the procedure. It offers quasi-identical results to MMD and thus makes a very attractive alternative.  相似文献

In the fall of 2014, the Government of Canada formally split the role of the Chief Public Health Officer (CPHO) into two positions: the CPHO and the President of the Public Health Agency of Canada. Despite concerns raised by the public health community, these changes are consistent with the CPHO's authority. However, the nature of responsible government means that the CPHO cannot simultaneously serve as an independent advocate for policies and programs that might prevent disease and as a senior advisor to the government of the day.  相似文献

Since the 1990s, most Western countries have equipped themselves with frameworks and tools to measure health organizations and systems' performance. Paradoxically, several theoretical, methodological and usage issues remain unresolved. Conceptually, the notion of performance is vague and not well rooted in theory. From a methodological perspective, we are faced with numerous measures that don't always meet reliability, validity and usefulness criteria and don't help to grasp the complexity of the concept. Finally, the assessment results are not fully used to continuously improve performance. This article focuses on analyzing these issues by deconstructing the myths that slow down the development of better‐suited frameworks to meet decision‐makers' needs. It also proposes innovations based on the global and integrated assessment model of health systems.  相似文献
