An innovative and shared methodology for event reconstruction using images in forensic science

This study presents an innovative methodology for forensic science image analysis for event reconstruction. The methodology is based on experiences from real cases. It provides real added value to technical guidelines such as standard operating procedures (SOPs) and enriches the community of practices at stake in this field. This bottom-up solution outlines the many facets of analysis and the complexity of the decision-making process. Additionally, the methodology provides a backbone for articulating more detailed and technical procedures and SOPs. It emerged from a grounded theory approach; data from individual and collective interviews with eight Swiss and nine European forensic image analysis experts were collected and interpreted in a continuous, circular and reflexive manner. Throughout the process of conducting interviews and panel discussions, similarities and discrepancies were discussed in detail to provide a comprehensive picture of practices and points of view and to ultimately formalise shared know-how. Our contribution sheds light on the complexity of the choices, actions and interactions along the path of data collection and analysis, enhancing both the researchers' and participants' reflexivity.

Vers une intégration des connaissances: dialogue épistémologique entre science forensique et criminologie

Bien que la science forensique et la criminologie partagent un objet commun, le crime comme réalité physique et sociale, elles tendent à se construire de manière indépendante et ont une propension à se profiler comme des disciplines bien établies et distinctes l'une de l'autre. A contre-courant, le présent article esquisse des pistes de réflexion sur le projet de construction de connaissances avancé par une cohorte de chercheurs convaincus de l'attrait de l'interface entre criminologie et science forensique. En particulier, nous visons à stimuler le débat et amorcer une réflexion croisée sur la manière dont le phénomène criminel est érigé en objet de connaissance, tant en science forensique qu'en criminologie. Nous affirmons que ces deux champs d'étude d'un même objet ont plus en commun que leurs praticiens ne le prétendent et proposons un dialogue visant à entrevoir les bénéfices d'une démarche à la fois plus ouverte et plus entremêlée de la criminologie et de la science forensique

Explorer les intersections entre la science forensique et la criminologie au travers de la temporalité de trois types d'actions de contrôle social

Our contribution aims to explore some intersections between forensic science and criminology through the notion of time. The two disciplines analyse the vestiges of illicit activities in order to reconstruct and understand the past, and occasionally to prevent future harms. While forensic science study the material and digital traces as signs of criminal activities and repetitions, criminology contributes to the acquisition of knowledge through its analysis of crime, its authors and victims, as well as social (re)actions to harmful behaviours. Exploratory, our contribution proposes a conceptual delimitation of the notion of time considering its importance in the study of criminality and harms. Through examples, we propose a "crimino-forensic" analysis of three types of actions of social control - prevention, investigation and intelligence - through their respective temporality (before, near or during and after the criminal activity or harm). The temporal issues of the different methodologies developed to appreciate the efficiency of these actions are also addressed to highlight the connections between forensic science and criminology. This attempt to classify the relations between different times and actions of social control are discussed through the multiple benefits and challenges carried out by the formalisation of fusing those two sciences. Notre contribution vise à explorer quelques intersections entre la science forensique (ou criminalistique) et la criminologie au travers de la notion de temps. En effet, les deux disciplines ont en commun qu'elles analysent les vestiges du phénomène criminel pour tenter de reconstruire et comprendre le passé et parfois prévenir de futurs incidents. Alors que la science forensique étudie les traces matérielles et numériques comme signe d'activités et de répétitions criminelles, la criminologie contribue à l'avancée des connaissances en ce domaine par son analyse des comportements contraires aux normes, de leurs auteurs et de leurs victimes, ainsi que des (ré)actions sociales à ces comportements. A but exploratoire, notre contribution propose une délimitation conceptuelle de la notion de temps en regard de l'importance que revêtent ses différentes manifestations dans l'étude de la criminalité. A l'appui d'exemples, nous proposons une analyse « crimino-forensique » de trois types d'action de contrôle social - la prévention, l'investigation et le renseignement - en fonction de leur temporalité respective (avant, proche voire pendant et après l'activité criminelle). Les enjeux temporels entourant les différentes stratégies méthodologiques développées pour apprécier l'efficacité de ces actions sont aussi abordés pour mettre en évidence des pistes d'intégration entre la science forensique et la criminologie. Cet essai de classification des relations entre les temps et ces trois actions de contrôle social est discuté sous l'angle des bénéfices, multiples, mais aussi des défis, que pose la formalisation des liens entre ces deux disciplines des sciences criminelles.

The Role of the Subjectivist Position in the Probabilization of Forensic Science

This paper is concerned with the contribution of forensic science to the legal process by helping reduce uncertainty. Although it is now widely accepted that uncertainty should be handled by probability because it is a safeguard against incoherent proceedings, there remain diverging and conflicting views on how probability ought to be interpreted. This is exemplified by the proposals in scientific literature that call for procedures of probability computation that are referred to as "objective," suggesting that scientists ought to use them in their reporting to recipients of expert information. I find such proposals objectionable. They need to be viewed cautiously, essentially because ensuing probabilistic statements can be perceived as making forensic science prescriptive. A motivating example from the context of forensic DNA analysis will be chosen to illustrate this. As a main point, it shall be argued that such constraining suggestions can be avoided by interpreting probability as a measure of personal belief, that is, subjective probability. Invoking references to foundational literature from mathematical statistics and philosophy of science, the discussion will explore the consequences of this interdisciplinary viewpoint for the practice of forensic expert reporting. It will be emphasized that-as an operational interpretation of probability-the subjectivist perspective enables forensic science to add value to the legal process, in particular by avoiding inferential impasses to which other interpretations of probability may lead. Moreover, understanding probability from a subjective perspective can encourage participants in the legal process to take on more responsibility in matters regarding the coherent handling of uncertainty. This would assure more balanced interactions at the interface between science and the law. This, in turn, provides support for ongoing developments that can be called the "probabilization" of forensic science.

Understanding academics' popular science publishing : institution culture and management style effects

Most universities and higher education systems have formally taken up a third mission, which involves various public outreach and engagement activities. Little is known regarding how higher education institutions' organisations interact with academic's level of public outreach. This article examines to which extent the perceptions academics have of their institutions' culture and management style, as well as some of their own individual and statutory characteristics interact with their level of public outreach. Using the Academic Profession in Europe comparative and quantitative research database, this article focuses on two countries on the extremities of the spectrum - Switzerland and the United Kingdom.

L'examen des plumes en science forensique

L'investigateur forensique est confronté à une vaste typologie de traces qui comprend notamment les plumes d'oiseaux. La présente contribution a pour but de fournir les éléments nécessaires pour mieux discerner le potentiel informatif de ces dernières et donner un aperçu global des différents examens pouvant être réalisés sur les plumes dans un contexte forensique. Il s'agit également de mettre en évidence les avantages et les limitations de chaque méthode ainsi que leur capacité de discrimination. Cet article présente finalement plusieurs exemples d'affaires dans lesquelles un examen de plumes a contribué de manière non négligeable à l'enquête et propose des pistes de réflexion sur le traitement et l'exploitation de ce type particulier de traces dans le futur.

Literature report : a review of policy learning in five strands of political science research

This paper reviews the policy learning literature in political science. In recent years, the number of publications on learning in the political realm increased dramatically. Researchers have focused on how policymakers and administrators adapt policies based on learning processes or experiences. Thereby, learning has been discussed in very different ways. Authors have referred to learning in the context of ideas, understood as deeply held beliefs, and, as change and adaptation of policy instruments. Two other strands of literature have taken into consideration learning, namely the diffusion literature and research on transfer, which put forward learning to understand who learns from whom and what. Opposed to these views, political learning emphasizes the adaptation of new strategies by policymakers over the transfer of knowledge or broad ideas. In this approach, learning occurs due to the failure of existing policies, increasing problem pressure, scientific innovations, or a combination of these elements.

Wonderalp. Une science émerveillée. Les Alpes et la culture de la curiosité

WonderAlp est un cabinet de curiosités réalisé à partir d'une documentation provenant d'anciens ouvrages de voyages dans les Alpes. L'app présente des images de dragons, de fossiles, de cristaux, de plantes, d'animaux, de phénomènes naturels. Elle donne des clés pour retrouver et comprendre l'émerveillement devant la nature qui animait la science à l'époque de la curiosité (XVIe-XVIIIe siècles). WonderAlp is a cabinet of curiosities that transforms your iPad or Android into an Early Modern Wunderkammer. It displays objects discovered in the Alps during the early period of exploration. These are grouped under three titles : "Dragons of the Alps", "Fossils and Crystals", "Plants to Landscapes". It helps apprehend a natural world that is both rational and wonderful, scholarly and popular, unlike the compartmentalized thinking of modern life.

The local configuration of a science and innovation policy : a city into the nanoworld

Local trajectories and arrangements play a significant role because the development of a research field, such as nanoscience and nanotechnology, requires substantial investments in human and instrumental resources. But why are there often concentrated in a limited number of places? What dynamics lead to such concentration? The hypothesis is that there is an assemblage of heterogeneous resources through the action of local actors. The chapter will explore, from an Actor Network Theory (ANT) perspective, how the local emergence of research dynamics from: the revival of local traditions, the local and national action of institutional entrepreneurs, controversial dynamics, and researchers' arrangements to involve other actors. It will examine how they connect up with each other and mutually commit themselves to the development of new technologies. It will focus on the role of narratives in this assembling: how were the local narratives of the past mobilized and to what effect.

Statistical hypothesis testing and common misinterpretations: should we abandon p-value in forensic science applications?

Many people regard the concept of hypothesis testing as fundamental to inferential statistics. Various schools of thought, in particular frequentist and Bayesian, have promoted radically different solutions for taking a decision about the plausibility of competing hypotheses. Comprehensive philosophical comparisons about their advantages and drawbacks are widely available and continue to span over large debates in the literature. More recently, controversial discussion was initiated by an editorial decision of a scientific journal [1] to refuse any paper submitted for publication containing null hypothesis testing procedures. Since the large majority of papers published in forensic journals propose the evaluation of statistical evidence based on the so called p-values, it is of interest to expose the discussion of this journal's decision within the forensic science community. This paper aims to provide forensic science researchers with a primer on the main concepts and their implications for making informed methodological choices.

"A Hard Battle to Fight": Natural Theology and the Dismal Science, 1820-1850

William Whewell's and Richard Jones's criticism of Jeremy Bentham's and David Ricardo's "dismal" views on the relation of theory and evidence in political economy was motivated by the former's views on the structuring role of natural theology for questions of method and evidence in the sciences, including political economy. In comparison, natural theology was for Richard Whately as structuring on these issues as it was for the Cambridge men. Whately's view on natural theology, however, conformed with the Ricardian predilection for theory over facts. The differences between the Cambridge men and Whately became manifest after (or better: during) the publication of Jones's book on rent in 1831 and led to a somewhat acerbic exchange of views on the role of definitions in science and the use of history for establishing scientific evidence. As far as political economy was concerned, Whately's stance carried the day in Victorian England.
