The Legality of the Image

Intimate links exist between political power, law and images. Theology, philosophy and law have always developed elaborate rules about visuality. The iconophilic and iconoclastic traditions complemented one another and combined to construct subjectivity and to reconcile humanity with finitude. In modernity, law replaced religion and philosophy conceptualised legality through the aesthetic category of the sublime. The law understands the importance of the governance of images for the maintenance of the social bond and helps organise a regime of permitted images and forbidden idols which amounts to a complex legal administration of aesthetics and a related aesthetic organisation of law.

An assessment of the 2000 US presidential election: a set of political marketing guidelines

This paper comprises a set of marketing guidelines using the 2000 presidential election as an example, and analysing the image building of the two candidates, Al Gore and George W. Bush. It is not hard to understand, with hindsight, why Bush was the winner. Copyright © 2001 Henry Stewart Publications     

Explosion Scene Forensic Image Interpretation

Image interpretation is an important aspect in the field of forensic science; however, it is seldom reported how to use these techniques in explosion scene forensic investigations. On 12 August 2015, a series of explosions killed 165 people and injured hundreds more at a container storage station at the Port of Tianjin. In this study, we applied image interpretation methods to determine the seat of the explosion by analyzing low‐quality video clips of the event. The interpretation fits well with recently published standard operating procedures, including the hypothesis, evaluation, inference, and confirmation. Image processing was adopted to enhance the images while the explosion scene was reconstructed with the same images. Some important features were extracted and utilized to distinguish whether the flashes were caused by reflection or a real blast. We reveal the real explosion location, which guides the overall investigation. The results indicate that image interpretation is a powerful tool for forensic investigators to analyze low‐quality images in complicated explosions or fire accidents.     

How long does it take? An exploration of the time between case assignment and a detective’s first investigative activity

Citizens and victims perceive the criminal justice system to be protracted. Blame for lengthy delays has disproportionately fallen on detective work. To that end, these analyses explore how long it took 184 detectives to work index crimes. Data suggest that more serious crimes, cases with a known suspect, and offenses that did not result in an arrest are most likely to be investigated and worked more promptly by detectives. Detectives, however, continue to exercise a great deal of discretion in if and when cases are worked once they are assigned. These findings are discussed as they relate to police performance indicators, the allocation of departmental resources, issues of crime control, and citizen satisfaction with the police.     

Fear of terrorism: media exposure and subjective fear of attack

In many Western countries, citizen knowledge of terrorist events is intrinsically shaped by the style of broadcasted messages published by the media. Media discourses regarding terrorist acts raise questions about how such rhetoric elicits fear in people who typically experience such events through news reports. However, we do not fully understand the impact of the media on perceptions of terrorism as clearly as we understand the relationship between the media and fear of crime. This study examines how media sources accessed actively (e.g. through newspapers; Internet) or passively (e.g. through television; radio) influence knowledge and fear of terrorism. We find receiving information about terrorism from multiple media sources increases fear of terrorism, but media sources accessed passively are not as influential as media sources accessed more actively. These results highlight how media consumption from various sources may affect one’s fear of terrorism, and further illustrates how the role of perceived knowledge may exacerbate or mitigate fear. Implications for policy and practice are discussed.     

Effect of History and Context on Forensic Pathologist Interpretation of Photographs of Patterned Injury of the Skin

In a previous study, a survey‐based analysis of pathologist diagnoses of patterned injury was performed. Subjects were provided with photographs of “classic” injuries and asked to diagnose the lesion in the absence of history or context. There was a relatively low diagnostic consensus among respondents. A second survey suggested that the disparate answers were not due to a strong belief in different diagnoses, but instead reflected how the respondents dealt with ambiguity. A third survey was created that asked participants to evaluate patterned injuries of the skin, but provided history and contextual information. The addition of history and contextual information increased consensus from a median of 80% to 98% on a per‐question basis. Confidence increased from a median of 56%–92%. These results demonstrate the importance of history and context in medical diagnosis of patterned injuries of the skin.     

Access to party positions and preference formation: a field experiment

Abstract: Surveys are sometimes used to assess preferences towards policy issues that are remote from experience and that have never been publicly discussed. How do these preferences of isolated survey respondents compare with preferences expressed by voters who have access to advice from competing political parties? I address this question by conducting a field experiment with a sample of the general public in which I experimentally control the subjects’ access to the actual positions of competing parties and interest groups on specific novel policy propositions. Access to party positions decreased approval of the proposed environmental policy among right‐wing voters by over fifty percent, and this effect was similar for different educational groups. When voters had access to party positions, their policy preferences were more consistent with their general political orientation. I conclude by discussing implications of these results for the debate about voter competence and for preference elicitation using surveys.     

The dynamic character of disguise behavior for text-based, mixed, and stylized signatures

The aims of this study were to determine if dynamic parameters (duration, size, velocity, jerk, and pen pressure) differed for signing style (text-based, stylized, and mixed) and if signing style influences handwriting dynamics equally across three signature conditions (genuine, disguised, and auto-simulation). Ninety writers provided 10 genuine signatures, five disguised signatures, and five auto-simulated signatures. All 1800 signatures were collected using a digitizing tablet resulting in a database of each signature's dynamic characteristics. With genuine signatures, there were significant differences between styles for size, velocity, and pen pressure, and there were significant differences between genuine signatures and at least one of the un-natural signature conditions for all parameters. For velocity and size, these changes with condition were dependent on style. Changes with condition for the other parameters were similar for the three styles. This study shows that there are differences among natural signature styles and disguise behaviors that may be relevant in forensic signature examinations.     

Evaluation of maxillary sinus dimensions in gender determination using helical CT scanning

Gender determination is an important step in identification in forensic medicine. CT measurements of maxillary sinuses may be useful to support gender identification. This study was undertaken to study the accuracy and reliability of maxillary sinus dimensions measurement in gender classification through the use of reconstructed helical CT images. Eighty-eight patients (43 men and 45 women) with age range from 20 to 49 years were selected in this study. The width, length, and height of the maxillary sinuses in addition to the total distance across both sinuses were measured. Data were subjected to discriminant analysis for gender using multiple regression analysis. Maxillary sinus height was the best discriminant parameter that could be used to study sexual dimorphism with an overall accuracy of 71.6%. Using multivariate analysis, 74.4% of male sinuses and 73.3% of female sinuses were sexed correctly. The overall percentage for sexing maxillary sinuses correctly was 73.9%. It can be concluded that reconstructed CT image can provide valuable measurements for maxillary sinuses and could be used for sexing when other methods of sexing are not conclusive.
