Abstract:

In this thesis I explore radio detection and ranging (RADAR) and software defined radio (SDR) in the context of wireless passive sensor interrogation. A RADAR topology is selected based upon preliminary measurements using ordinary laboratory instrumentation and then used for construction of a prototype X-band wireless measurement system using commercial, off-the-shelf (COTS) components. This research explores the feasibility of wireless passive sensor interrogation through practical application of SDR and RADAR techniques to the interrogation of a wireless passive resonator signal. This work serves as a foundation for further research on sensor interrogation through establishment of critical system parameters in the design of wireless measurement systems.

Abstract:

This thesis proposes and develops a novel optic configuration, Kerr phase-interrogator, which investigates the phase-shift between two sinusoidally modulated optical signals (SMOS) utilizing Kerr effect. The Kerr phase-interrogator gives birth to an entirely new technique for measuring the phase-shift between two light-waves. Taking advantage of all-optical signal processing, ultrafast responses, and being free from the coherent properties of a laser source, the Kerr phase-interrogator based technique for measuring the phase-shift is a promising novel approach for monitoring and sensing applications. The thesis begins with theoretically demonstrating the operation of Kerr phase-interrogator. As the core of optical process occurs in Kerr phase-interrogator, nonlinear interactions between two SMOSs in the Kerr medium are theoretically analyzed utilizing the models of nonlinear phase-modulation and four-wave mixing (FWM). The phase-modulation-based model is intuitive and allows for conceptual understanding of the operation of the Kerr phase-interrogator. However, this model does not account for the impact of chromatic-dispersion (CD) of the Kerr medium on the operation of the Kerr phase-interrogator. Compared with the former model, the FWM-based model is essential for acquiring insight into Kerr phase-interrogator, and can explain the CD impact of the Kerr medium. The analytical solution of the power of the first order sideband as a result of the nonlinear interaction is obtained in both theoretical models. The obtained solution shows sinusoidal dependence of the power on the phase-shift of the SMOSs. Utilizing this sinusoidal dependence, the phase-shift of two SMOSs can be acquired by measuring the power of the first-order sideband. Birefringence and CD are critical factors that affect the nonlinear interactions and thus impact the operation of Kerr phase-interrogator. In this work, vector analysis is performed on the nonlinear interaction between two SMOSs in a Kerr medium with randomly varying birefringence, and the effect of polarization-states of SMOSs on the operation of Kerr phase-interrogator is investigated. Impact of CD of Kerr medium on the operation of Kerr phase-interrogator is theoretically investigated using theory of FWM and is experimentally verified. Four typical applications, which comprehensively reflect the advantages of Kerr phase-interrogator, are proposed and experimentally demonstrated in this thesis. First, we present a novel approach for measurements of CD in long optical fibers using a Kerr phase-interrogator. The Kerr phase-interrogator measures the phase variation of a SMOS induced by CD in a fiber under test as the laser carrier wavelength is varied. This approach takes advantage of all-optical signal-processing based on Kerr effect to acquire the phase variation, and consequently removes the requirement of complex electrical signal-processors in existing techniques of CD measurement. CD measurement for several fibers is experimentally demonstrated. Second, a novel temperature sensor that utilizes temperature dependence of reflection group-delay in a linearly chirped fiber Bragg grating is presented. The reflection group-delay of chirped grating changes with temperature leading to a variation in the phase of a SMOS reflected from the grating. A Kerr phase-interrogator converts the phase-variation into power variation allowing for temperature sensing with a resolution of 0.0089 oC and a sensitivity of 1.122 rad/oC. Third, a Kerr phase-interrogator is applied for implementation of real-time CD monitoring. CD induces a phase-shift between two SMOSs carried by two different wavelengths. A Kerr phase-interrogator converts the phase-shift into power variation and CD monitoring is achieved by measurement of the power variation in real time with a resolution of 0.196 ps/nm. This application takes advantages of ultrafast response of Kerr phase-interrogator and achieves the real-time monitoring. Lastly, a novel approach for incoherent optical frequency-domain reflectometry based on a Kerr phase-interrogator is presented. The novel approach eliminates the limitation of finite coherent length of the light source, and achieves measurement of long-range distance beyond the coherent length of the light source. Long-range detection of reflection points as far as 151 km at a spatial-resolution of 11.2 cm is experimentally demonstrated.

Abstract:

Post-modern feminist security studies explore how our discourse about gender and war affects the construction of security as a concept. Military narratives valorizing the masculine over the feminine have long marginalized women warriors. In recent years, images of the torture and abuse of detainees have appropriated the representation of women interrogators during the Global War on Terrorism in particular. This research applied interpretative phenomenological analysis to the narratives of women interrogators in order to challenge the silence concerning their lived experiences by addressing how women interrogators understand their experiences both as woman and as interrogators, and how they negotiated socially constructed contradictions between these identities. Based on an analysis of semi-structured interviews with eight participants, the findings produced seven, interrelated themes. First, the findings explored the integration of gender with other markers of identity. Next, the findings demonstrated women interrogators recognize gender as a context-dependent role negotiated within the military institution through the development and demonstration of technical prowess. Then, the findings described interrogation as a complex adaptive system in which women interrogators harnessed to achieve their goals. Finally, the findings determined that the intersection of women interrogators’ identities and their interactions in the context of interrogation operations generated the perception of women interrogators as non-threatening. Women interrogators learned to exploit the meaning of this emergent phenomenon through introspection and the development of self-awareness.

Abstract:

The lack of passive, wireless, chemical and biological sensor systems is a significant impediment to sensor system applications. While active sensors with a wireless communications link continue to decrease in power consumption, they still require a power source, such as a battery. This active power consumption limits the useful life of the sensor and its applications. A more attractive solution would be a passive, wireless, chemical and biological sensor integrated with a wireless interrogation platform to monitor the sensor. The focus of this thesis is the realization of a wireless sensor interrogator capable of monitoring multiple, passive, resonant-frequency sensors. It is demonstrated, using Frequency Modulation Spectroscopy techniques, that the resonant frequency of a passive sensor can be detected and tracked over time. Simulated results are presented that verify the functionality of the proposed wireless sensor interrogator. In addition, an experimental hardware setup and subsequent experimental results are presented that verify the simulation results. Considerations for the design of the wireless sensor interrogator and opportunities for future research are discussed.

Abstract:

This dissertation investigates the use of the harmonic radar technique for passive wireless sensing applications. Issues of DC power consumption, high RF activation power, large node size, and short communication range associated with the existing passive wireless sensing technologies are addressed by the development of novel, completely passive, high efficiency, compact 3-D harmonic sensor nodes. The node transceiver employs a passive frequency doubler to return the second harmonic of the interrogation signal, and electrically-small 3-D antennas to achieve the compactness and high efficiency. The developed nodes fit inside a sphere with a diameter < 3 cm and achieve communication range > 60 m using a 43 dBm EIRP interrogator. Effective modulation is demonstrated experimentally using low cost commercial vibration sensors. To address major challenges associated with long-range, embedded, passive wireless sensing including sensor node identification and remote channel calibration, a 3-D dual-channel transceiver is developed. To the best of the author's knowledge, the presented dual-channel transceiver is the first completely passive design with built-in passive remote channel calibration and identification capabilities, and the presented nodes have the best overall performance among previously published designs, in terms of conversion efficiency, communication range, and occupied volume. To reduce the cost and weight and improve the manufacturing process of the proposed nodes, the 3-D digital additive manufacturing and conformal direct printing technologies are employed. The harmonic interrogator antenna design is also an underlying focus of this work. Different interrogator antenna candidates are developed based on different design approaches. The first approach is based on the use of dual-channel antenna array, where one channel is used for transmission and the second channel is used for reception. Two dual-channel harmonic interrogator antennas that consist of 4-element circular patch antenna arrays and 2-element quasi-Yagi dipole antenna arrays are implemented. The second approach employs mechanically reconfigurable antennas to reduce the size and maintain persistent radiation properties over wide frequency bandwidth. Two mechanical reconfiguration methods are developed; the first method is based on the use of Hoberman's planar foldable linkage to vary the operating frequency of planar circular patch antennas and the second mechanical reconfiguration method is based on the use of a rack and pinion mechanism to reconfigure dual-band slot antennas. The third approach employs a single channel multi-octave Vivaldi antenna to provide the capability to interrogate a large number of harmonic tags that are widely spaced in frequency. To improve the antenna radiation performance over a broad frequency range, a new method based on the introduction of a parasitic elliptical patch in the flare aperture is proposed. This method enables gain and bandwidth improvement compared to what has been reported for Vivaldi antennas with a compact size. To provide the interrogator the capability to steer the radiation beam for locating and tracking sensor nodes, a topology to develop a miniature, non-dispersive switchable 4-bit phase shifter is proposed on the basis of composite right/left handed transmission line unit cells.

Abstract:

This dissertation focuses on developing new technologies for ultra-low-cost sapphire fiber-optic high-temperature sensors. The research is divided into three major parts, the souceless sensor, the simple Fabry-Perot (F-P) interrogator, and the sensor system. Chapter 1 briefly reviews the background of thermal radiation, fiber optic F-P sensors, and F-P signal demodulation. The research goal is highlighted. In Chapter 2, a temperature sensing system is introduced. The environmental thermal radiation was used as the broadband light source. A sapphire wafer F-P temperature sensor head was fabricated, with an alumina cap designed to generate a stable thermal radiation field. The radiation-induced optical interference pattern was observed. We demodulated the temperature sensor by white-light-interferometry (WLI). Temperature resolution better than 1°C was achieved. Chapter 3 discusses a novel approach to demodulate an optical F-P cavity at low-cost. A simple interrogator is demonstrated, which is based on the scanning-white-light-interferometry (S-WLI). The interrogator includes a piece of fused silica wafer, and a linear CCD array, to transform the F-P demodulation from the optical frequency domain to the spatial domain. By using the light divergence of an optical fiber, we projected a tunable reference F-P cavity onto an intensity distribution along a CCD array. A model for S-WLI demodulation was established. Performance of the new S-WLI interrogator was investigated. We got a good resolution similar to the well-known traditional WLI. At last, we were able to combine the above two technologies to a sapphire-wafer-based temperature sensor. The simple silica wafer F-P interrogator was optimized by focusing light to the image sensor. This approach improves the signal to noise ratio, hence allows the new integrator to work with the relatively weak thermal radiation field. We, therefore, proved in the experiment, the feasibility of the low-cost sourceless optical Fabry-Perot temperature sensor with a simple demodulation system.

Abstract:

The thesis comprises a dissertation, a linking piece and a collection of poems. The dissertation is an analysis of state-imposed censorship in Iranian poetry from 1979 through 2014. It investigates the state's rationale for censorship, its mechanism and its effects in order to show how censorship has influenced the trends in poetry and the creativity of poets during the period studied. The introduction outlines attitudes towards censorship in three different categories: Firstly, censorship as "good and necessary", then censorship as "fundamentally wrong yet harmless or even beneficial to poetry", and lastly, censorship as a force that is always destructive and damages poetry. Chapter one investigates the relevant laws, theories and cultural policies in order to identify the underlying causes for censorship of poetry. Chapter two looks at the structure and mechanism of the censorship apparatus and examines the role of cultural organizations as well as judicial and security forces in enforcing censorship. Chapter three contemplates and explores the reaction of Iranian poets to censorship and different strategies and techniques they adopt to protest, challenge and circumvent censorship. Chapter four analyses the outcome of the relationship between the censorship apparatus and the poets, providing a clear picture of how censorship defines, shapes and presents the poetry produced and published in Iran. Chapter five compares the type of censorship in Iran with two historical cases of Tsarist Russia and the Soviet Bloc to conclude that every censorship regime has particular characteristics and affects creativity in a unique way. It revisits the previous arguments in light of findings of the research and concludes that censorship in Iran has highly influenced the contemporary Iranian poetry, and that it leaves a lasting effect on creativity of the Iranian poets. Growing up with Censorship is a self-reflective memoir which chronicles the author’s personal encounters with censorship both as a reader and a writer from 1979 to 2014. It links the dissertation to the poems and provides an intimate narrative of the role censorship has played in shaping the author’s poetic life and his poetry. The Kindly Interrogator is a portfolio of 57 poems concerned with the themes of censorship, surveillance and persecution.

Abstract:

La confession en contexte d’interrogatoire policier est un élément important de l’enquête afin d’accumuler des preuves (Inbau, Reid, Buckley, et Jayne, 2001), résoudre le crime sous enquête (Phillips et Brown, 1998), et pour prouver la culpabilité d’un individu (Leo, 1996). Jusqu’à présent, les recherches effectuées dans ce domaine ont majoritairement mis l’accent sur l’identification des facteurs et motivations qui influencent la décision de confesser les faits reprochés. La non-confession a donc, jusqu’ici, pratiquement toujours été considérée par les chercheurs de façon implicite : ce qui ne favorise pas une confession doit donc nécessairement favoriser la non-confession. Aucun chercheur ne s’est véritablement attardé à valider cette présupposition ni à décrire le processus décisionnel de non-confession. Cette étude vise donc à combler un vide de connaissances au sujet des motivations sous-jacentes à la non-confession en se basant sur un échantillon de 111 hommes non-confesseurs, ayant été reconnus coupables des faits reprochés, et détenus dans un pénitencier canadien. Des analyses de classes latentes effectuées avec certains des facteurs motivationnels reconnus dans la littérature sur la confession ont aidé à identifier cinq profils distincts de non-confession : le déni passif et le déni ambivalent, deux profils pour lesquels les motivations n’ont pas su être bien identifiées à l’aide des variables à l’étude ; le déni émotif, qui est motivé par plusieurs facteurs, particulièrement par ceux liés aux émotions et aux pressions internes (ex. : la peur de perdre un être cher) ; le déni calculé, déni qui semble basé sur une analyse coûts-bénéfices ; et finalement, le déni pour protéger sa dignité, ces non-confesseurs ayant principalement peur de ternir leur réputation. Les résultats de l’étude, discutés à la lumière des recherches sur l’interrogatoire policier et les stratégies d’interrogatoire, ont d’importantes retombées au niveau des pratiques d’interrogatoire et ont aussi d’importantes implications dans l’avancement des connaissances théoriques sur la non-confession et sur l’interrogatoire policer, domaine encore très peu étudié, particulièrement au Canada.
Suspect’s confession during police interrogation is an important component of successful police investigations. Confession has been shown to play an important role in the corroboration of incriminating facts (Inbau, Reid, Buckley, & Jayne, 2001), to help solve crimes (Phillips & Brown, 1998), and to lay charges and prove guilt (Leo, 1996). While prior and more recent studies helped to further our knowledge regarding profiles of motivations and factors associated with suspects’ confession during police interrogation, not much is known about the motivations associated with a suspect’s non-confession. Using a sample of 111 individuals who have been convicted—despite the fact that they had not confessed their crime—and incarcerated in a Canadian penitentiary, the current study tries to better understand the different profiles of motivations leading to a non-confession during police interrogation. Using selected motivational factors, latent class analyses were performed and helped identify five subgroups of non-confessors: passive denial and ambivalent denial, two profiles for which the motivational factors used in the current did not fully helped to understand their decision-making, emotional denial, which is motivated by several factors, particularly those related to emotions and internal pressures (e.g. fear of losing loved ones), calculated/rational denial, a group of non-confessor for which the decision not confess seemed to be the result of a cost-benefit analysis, and finally, dignity denial, since these non-confessors were mainly afraid to undermine their reputation. Findings, discussed in light of the literature on police interrogation and interrogation techniques, have important practical implications, both in terms of human rights and effective practices within police agencies. The study results also have important implications for the advancement of theoretical knowledge in the field of non-confession and police interrogation, an area that is still well understudied, particularly in Canada.

Abstract:

En pharmaco-épidémiologie, la mesure de l’exposition médicamenteuse est fondamentale. Des données déclaratives recueillies par interrogatoire des sujets ou des données extraites des bases de remboursement de l’Assurance Maladie peuvent être utilisées. Les objectifs de ce travail étaient de comparer l’exposition mesurée à partir de ces deux sources de données et d’évaluer l’impact du choix de l’une ou l’autre source sur les mesures de risque dans les études étiologiques. Les travaux ont été conduits au sein de l’étude des Trois-Cités, cohorte de sujets âgés pour laquelle étaient disponibles des données déclaratives et de remboursement. La concordance entre les expositions issues des deux sources ou la validité de l’exposition issue de l’une par rapport à celle issue de l’autre ont été évaluées dans différents contextes. La survenue d’événements a été simulée dans la population et des études cas-témoins nichées ont été conduites pour évaluer l’association entre l’exposition issue de chaque source et chaque événement. Pour les médicaments cardiovasculaires, les mesures d’exposition étaient peu différentes entre les deux sources. L’impact du choix de l’une ou l’autre source sur les mesures d’association entre l’exposition et un événement était faible. Pour les benzodiazépines ou les anti-inflammatoires non stéroïdiens, des différences étaient observées entre les expositions issues des deux sources. Pour ces médicaments, l’association avec un événement pouvait varier selon la source utilisée. Pour des médicaments pris de manière irrégulière ou intermittente, le choix de la source de données pour la mesure de l’exposition peut donc être un élément déterminant
In pharmacoepidemiology, assessment of drug exposure is fundamental. It can rely on data collected through patient interviews or extracted from healthcare insurance system databases recording reimbursement claims. This work aimed to compare drug exposure measured from these two data sources and to evaluate the impact of choosing one source or the other on risk estimates in etiological studies. It was conducted as part of the Three-City Study, a cohort of French elderly persons for which both interview and reimbursement data were available. Agreement between exposures measured from both sources or validity of exposure measured from one source with reference to that measured from the other were evaluated in different backgrounds. Simulated outcomes were generated in the study population and nested case-control studies were conducted in order to estimate the association between the drug exposure measured from each source and each simulated outcome. For cardiovascular system drugs, exposure measured from interview data was close to that measured from reimbursement data. The choice of one source or the other had few impact on the estimated associations between the exposure and an outcome. For benzodiazepines or non-steroidal anti-inflammatory drugs, exposure measured from both sources could differ. For these drugs, the association between the exposure measured from each source and an outcome could vary. For drugs that can be used irregularly or intermittently, the choice of the source of data for drug exposure assessment could thus be of great importance

L’objectif de cette recherche est de déterminer les facteurs explicatifs de la confession en contexte d’interrogatoire chez les cyberdélinquants sexuels ayant pour victimes des enfants. Pour ce faire, des analyses d’interrogatoires vidéos ont été réalisées. S’inscrivant dans un projet de recherche plus large, la présente étude est basée sur la codification et l’analyse de 80 interrogatoires vidéo menés par la division des enquêtes sur l’exploitation sexuelle des enfants sur Internet (ESEI) de la Sûreté du Québec. La codification de ces interrogatoires vidéo a été faite grâce à une grille de codification développée dans le cadre du projet et composée de 137 variables regroupant, notamment, des informations quant aux caractéristiques sociodémographiques, délictuelles et contextuelles des cas analysés. Les résultats obtenus tendent à confirmer l’importance des variables contextuelles sur l’issue finale de l’interrogatoire (déni vs. confession partielle ou complète), et donc, la possibilité pour les enquêteurs de venir influencer le processus décisionnel du suspect par rapport à sa collaboration en contexte d’interrogatoire policier. Plus précisément ce sont les variables suivantes qui se sont avérés significativement reliées à la confession complète suite à une analyse de régression logistique : la durée de l’interrogatoire, le fait d’engager le suspect dès le départ dans la récapitulation de son arrestation ainsi que la relation entre l’interrogateur et le suspect.
The goal of this study is to determine which explanatory factors would influence confession during a police interrogation in cyber child sexual offense cases. In order to do so, video-recorded police interrogations were analysed. Part of a larger ongoing research project, the current study is based on the analyses of 80 video recorded interrogations conducted by Internet Child Exploitation (ICE) unit of the Sûreté du Québec. Interrogations were coded using a coding sheet specifically designed for this research project that included information regarding the suspect, the crime committed and the contextual characteristics of the interrogation. The results showed the importance and the role of contextual variables on the outcome of the interview and suggest that investigators do have the power to influence the suspect’s decision-making process to collaborate and confess their crime during police interrogations. More specifically, the length of the interrogation, the fact that the interviewer engaged the suspect into describing the recapitulation of the arrest and the relation between the interviewer and the suspect were found to be statistically related to the outcome of the interrogation.

Full text

Abstract:

Notre recherche a pour objet des interrogatoires médiatisés par interprète, en tant que pratiques langagières et discursives situées dans un contexte institutionnel donné, à savoir le tribunal. Parmi les divers contextes de nos sociétés contemporaines où les interprètes sont partenaires de l’échange au sein de dialogues effectifs, nous avons ciblé le contexte judiciaire, dont le caractère institutionnel et les enjeux en font un lieu formel et au fonctionnement normé : les interrogatoires s’y déroulant sont des échanges réglés et codés. Nous avons fait alors l’hypothèse que peut fonctionner à double titre la tension qui se crée ainsi entre les normes à l’œuvre au tribunal et la présence de sujets en interaction dont les enjeux et représentations peuvent considérablement différer : elle fonctionne d’une part comme loupe grossissante sur certains phénomènes qui, lorsqu’ils se produisent malgré la normativité ambiante, sembleraient alors relever de ce qui ne peut ne pas se produire en présence d’un interprète ; elle fonctionne d’autre part comme déclencheur d’événements particuliers et uniques propres au contexte, aux personnes concernés, aux enjeux spécifiques liés aux thèmes traités, aux dialogues ponctuels. L’analyse de dialogue que nous pratiquons consiste aussi bien à spécifier préalablement le cadrage externe de l’événement communicatif qu’à décrire comment la situation est perçue et évaluée par les participants à travers l’élaboration conjointe du sens. Notre problématique vise ainsi à dégager la relation existant entre les conventions socio-discursives propres à cette sphère d’activité et certains traits interactionnels et discursifs, engendrés par la participation du "tiers/interprète" à l’interrogatoire. L’approche discursive et dialogique a permis d’entreprendre une démarche analytique prenant en compte : un plan interlocutif, concernant la dynamique compositionnelle des échanges et les rapports de places, dialogal ; un plan énonciatif et dialogique concernant à la fois la présence des sujets dans leurs dires et la façon dont les discours sont élaborés par des mouvements interprétatifs qui peuvent être plus ou moins directement accessibles, notamment à travers ces réaménagements de sens que sont les reformulations inter-linguistiques de l’interprète. Les voix qui parcourent l’espace discursif en le rendant hétérogène peuvent par-là être identifiées. Ces pratiques d’interactions médiatisées peuvent alors être pensées sur un continuum de dispositifs allant des stratégies d’effacement énonciatif que l’interprète met en œuvre - afin de créer des discours objectivés -, aux procédés variés qui l’inscrivent dans le discours d’autrui, jusqu’à la prise en charge de ses propres discours en tant que locuteur/énonciateur à part entière. Enfin, les propriétés qui caractérisent les interrogatoires interprétés dans le contexte du tribunal s’avèrent propres non seulement au genre de discours institutionnel et juridique concerné mais également à la présence du "tiers", apte à influencer l’événement discursif "interrogatoire" à tous les niveaux pris en compte par l’analyse. Il semble alors que cela pourrait permettre d’appréhender ces dialogues comme un type, ou sous-genre, particulier du discours juridique
Our research focuses on interpreter-mediated examinations as situated oral exchanges and discursive practices in a specific institutional context, i.e. the courtroom. In contemporary societies, among the various situations where interpreters act and dialogue in face-to face interactions, the judiciary context proves to be one of those institutional domains where highly formal and normative practices take place. Examinations are very coded exchanges. Starting from the hypothesis that the tension which develops between laws and norms at work in this frame and the discursive productions by speakers directly dialoguing and interacting, whose representations and goals may consistently differ, may have a double effect on the interpreter-mediated event, we further investigate how : some specific interactional and discourse patterns realize in a such ritualized and normative context, attempting to understand if they are typical of interpreter-mediated interactions in general or of the specific examinations we observe ; and speakers’ identities, institutional roles, their personal goals and the specific themes concerned have an influence on these practices, producing very peculiar and singular patterns of sense-making. Hence, focusing on face-to-face interpreting practices, the dialogical and discourse approach we adopt allows to take into account : from one side, what relates to the dialogal dimension of the interaction, pertaining to a dialogue between two (or more) co-present interlocutors and the definitions of their identities, from what pertains to the dialogical one, having to do with dialogism or dialogicality in the more abstract senses. Given that understanding is related to responding, interpreters are seen as speakers actively involved in dialogue. The ways speakers leave traces of their presence in the utterances they produce, while they’re doing the interacting, and, particularly, the way in which the interpreter’s presence is sensed through thar interlinguistic reformulation of the other’s words which is translation gives access to the way in which sense-making is jointly created in the framework of a highly ritualized activity type such as examinations in the courtroom. In the end, interpreted-mediated examinations may be thought of as changing practices on a more/less continuum, going from : the cases where the interpreter translates as a reporter using the 1st person, using linguistics strategies allowing him/her to assume full responsibility for the words uttered without showing it; to all those cases of variation on the expected pattern which, at different degrees, let emerge his/her presence in the interpreting process; to the production of discourses for which s/he is entirely responsible, acting as a an autonomous speaker. These collectively constructed events may therefore suggest that there is a dynamic relation between expected practices in the discourse context and their actual realization. Interpreter-mediated examinations prove to be per se speech events, namely very specific exchanges with their often hybrid dynamics, within which all interlocutors - including the interpreter – dialogically contribute to understanding and to the creation of meaning

The modern Criminal Lawsuit has the remarkable characteristic of looking at the imputed person as someone who has rights, to privilege the biggest principle of the human being, conquered gradually. To start from the comprehension of the basis of the right to the silence, campared to the guided principle of the Democratic State of Right, emanates the logical of the doctrinal, the Legislator and the applicator of right to get together in order to give an exact application to the institute and its correspondings. The interrogation of an accused in a penal lawsuit, chance for him to be heard by the authority to present his version of the facts and to exercise his right of self-defense, since the old times, has changed a lot in its penal lawsuit system according to the ideological-social-cultural mentality of the historical moment. But the evolution of Science and Philosophy made new methods of investigation to come out. The accused started to be seen not as an evidence object but as someone who had rights. The right to remain silent started to be accepted as assurance of privacy and mainly as deduction of the principle against the self-incrimination. The study of principles which honor the right of being silent and its reflexes, and also of the investigation, makes evident the need of a discussion around the subject. It happens through the right of information, the supposed innocence, the contradiction, the wide defense, the prohibition of illicit evidences. The right to remain silent extends to all inquired person at the moment of his prision and in another case, by public officers, and also in the police investigation phase, in the instruction of the penal lawsuit and of parliamentary and administrative procedures, even when he is the witness or concerning to self-incriminative facts. So, it works in every moment that the inquired individual finds himself in front of answers which can harm him. It s a subjective public right that prevents disadvantageous interpretations against the one who is remaining silent. For its full exercise, it is necessary the information of this right to the titular and its extension as an exercise of free and aware will. The right of not being obliged to prove against himself permits to the accused not to help in producing evidences, translation of the right to preserve the privacy and inertness and specially the imputed person s spontaneous acts. And this work treats all this complexity in a unpretentious way
O moderno direito processual penal tem a destacada característica de avistar o imputado como sujeito de direitos a privilegiar o princípio maior da dignidade da pessoa humana, conquistado paulatinamente. A partir da compreensão do fundamento da garantia do direito ao silêncio, em cotejo com os princípios norteadores do Estado Democrático de Direito, emana a lógica da consonância do doutrinador, legislador e operador do direito de unirem-se para dar uma exata aplicação ao instituto com suas vertentes. O interrogatório do acusado no processo penal, oportunidade em que será ouvido pela autoridade para apresentar sua versão dos fatos e exercer seu direito de autodefesa, desde os tempos remotos, sofreu grandes alterações na sistemática processual de acordo com a mentalidade ideológico-social-cultural do momento histórico. Mas a evolução da ciência fez surgir novos métodos de investigação. O acusado passou a ser visto não como objeto da prova, mas como sujeito de direitos. O direito de silenciar passou a ser aceito como garantia da intimidade e, principalmente, como corolário do princípio contra a autoincriminação. O estudo dos princípios que prestigiam o direito ao silêncio e seus reflexos, bem como do interrogatório, evidencia a necessidade de debater o tema. Realiza-se através do direito à informação, da presunção de inocência, do contraditório, da ampla defesa, da proibição de provas ilícitas. O direito ao silêncio estende-se a toda pessoa questionada no momento da sua prisão e fora desta, por agentes públicos, bem assim na fase investigativa policial, na instrução do processo penal e dos procedimentos parlamentares e administrativos, mesmo quando estiver na qualidade de testemunha quanto a fatos auto-incriminatórios. Cabe em todo momento em que o indivíduo perquirido vê-se diante de respostas que possam prejudicá-lo. Trata-se de direito público subjetivo impeditivo da interpretação desfavorável contra aquele que silencia. Para seu pleno exercício, faz-se necessária a informação tanto deste direito ao titular como da amplitude de seu alcance como exercício da vontade livre e consciente, para que possa ser exercido plenamente. O direito de não ser obrigado a fazer prova contra si permite ao imputado não colaborar na produção da prova, tradução do exercício do direito de preservação da intimidade e inércia e, sobretudo, do agir espontâneo do imputado. É essa a complexidade tratada no presente trabalho

Abstract:

Cette thèse porte sur l'étude de l'entretien cognitif, une technique destinée à améliorer les souvenirs des témoins au moment de l'audition, c'est-à-dire à augmenter la quantité d'informations correctes restituées par le témoin sans augmentation des erreurs ou des affabulations. L'introduction théorique débute par une analyse critique des procédures d'audition employées par les policiers. Il est ensuite exposé les 2 fondements théoriques sur lesquels repose la technique : les notions de contexte et de script, suivi d'une revue de question de la littérature portant sur l'entretien cognitif. Il est aussi étudié une autre technique d'amélioration des souvenirs, l'encodage cognitif, employant plusieurs stratégies de l'entretien cognitif mais appliquées au moment de l'encodage. L'introduction est suivie par l'exposé d'un ensemble de 6 investigations menées dans le but de mettre à l'épreuve l'entretien cognitif et l'encodage cognitif. La 1ère recherche, impliquant des policiers, permet de mettre en évidence l'efficacité de l'entetien cognitif sur le terrain. La 2e confirme à la fois l'efficacité de l'entretien cognitif, mais aussi de l'encodage cognitif et de la complémentarité de ces dernières. La 3e fait apparaître à nouveau une efficacité des 2 techniques dans des conditions méthodologiques plus contrôlées et en présence d'émotion négative. La 4e permet de cerner l'efficacité de chaque constituant de l'entretien cognitif et de l'encodage cognitif. La 5e porte plus spécifiquement sur la recontextualisation mentale en fonction de la présence d'émotion négative et du lien sémantique émotion-événement. La 6e permet d'étudier l'efficacité des différentes règles de l'entretien cognitif en fonction du degré d'expertise des sujets par rapport à l'événement critique. Il est ensuite discuté des implications théoriques et pratiques des résultats présentés dans ce travail montrant une efficacité importante des techniques étudiées
The purpose of this thesis is to study the cognitive interview, a new technique designed to improve eyewitness memory at the time of examination, or, in other words, to increase the quantity of correct information recalled by the witness without a corresponding increase in errors or confabulations. The theoretical introduction begins by a critical analysis of procedures used by police officers. The two theoretical foundations of the cognitive interview are then exposed : notions of context and script, followed by a review of litterature on the cognitive interview. An another technique of memory improvement is also studied, the cognitive encoding, wich employs several strategies of the cognitive interview applied at the time of encoding. The introduction is followed by the presentation of six experiences carried out in order to test the effectiveness of cognitive interview and cognitive encoding. The first experience, involving police officers, demonstrates the effectiveness of the cognitive interview in a field perspective. The second one confirms the effectiveness of both the cognitive interview and the cognitive encoding, and the complementarity of the two techniques. The third one demonstrates once again the effectiveness of the two techniques in more controlled methodological conditions and in presence of negative emotion. The fourth one explores the effectiveness of each mnemonic components of the cognitive interview and the cognitive encoding. The fifth one examines specifically the effectiveness of the mental context reinstatement technique as a function of the presence of negative emotion and the semantic relation between the emotion and the critical event. The sixth one examines the effectiveness of each components of the cognitive interview as a function of subjects' expertise level in consideration of the critical event. Theorical and pratical implications of results obtained in this work, wich demonstrate a significant effectiveness of the cognitive interview, are then discussed

Abstract:

Les notions de strategie et de tactique, definis par clausewitz, peuvent etre transposees a la procedure criminelle. C'est sous cet angle, avec l'etude des forces en presence, des moyens tactiques mis en oeuvre et de la finalite poursuivie, que nous examinons la procedure criminelle suivie en bretagne, au xviiieme siecle. Une premiere phase revele les enquetes menees par la victime. Celle-ci prefere souvent agir par elle-meme, en dehors de tout contexte processuel, et trouve l'appui actif des tiers. Le premier moment capital de l'instance judiciaire met en presence du juge chacun des temoins de l'information. L'analyse des temoignages permet d'etablir leur sincerite et leur transcription minutieuse, a charge et a decharge. L'interrogatoire de l'accuse est un autre moment decisif de la strategie judiciaire. La pratique se revele en harmonie avec la doctrine. L'immense majorite des interrogatoires est exemple de tout caractere captieux et de toute question piegee. C'est exceptionnellement que l'interrogateur tend a forcer l'aveu. Les differents types de defense ont ete degages; et leur analyse montre que l'accuse breton, qu'il adopte une defense primaire ou sophistiquee, se defend avec une forte opiniatrete. Nous estimons, pour conclure, que la strategie visait essentiellement a la recherche de la verite.

Full text

Abstract:

À travers l’étude d’une cinquantaine de pièces, textes et spectacles, issues du répertoire européen contemporain, il s’agit d’envisager la représentation dramatique comme un fait anthropologique, mettant en jeu des pratiques du signe et de l’interprétation, à travers le prisme de l’enquête – entendue comme processus de création, comme forme structurante mais aussi comme mode de relation au monde et au spectateur. Parcours des hypothèses, laboratoire des fonctions cognitives et heuristiques de la représentation, il apparaît que l’enquête désigne ce trouble par lequel le théâtre se pense comme représentant quelque chose. Cette thèse inscrit donc les dramaturgies contemporaines à l’intérieur du paradigme indiciaire, identifié par C. Ginzburg, en regard des formes romanesques de l’enquête (roman naturaliste et policier). Elle entend ainsi réparer le déficit théorique dont souffre cette fiction maîtresse » (D. Kalifa), permettant ainsi de penser les significations de la reprise d’une démarche moderne, attachée à la recherche d’un sens et d’une lisibilité, dans une période marquée par le postmodernisme, caractérisée par une posture de relativisme et de suspens herméneutique. Le recours aux scènes du procès, de la reconstitution, de l’interrogatoire, étudié dans une seconde partie, découvre des opérations critiques et réflexives où les dispositifs de production du vrai sont interrogés comme autant de politiques et de poétiques du signe. Quant à l’écriture documentaire, qui fait l’objet d’une troisième partie, elle apparaît comme traversée par trois orientations distinctes – thétique, constatative et interrogative – que nous identifions à partir de leur rapport à l’enquête
Through the analysis of about fifty plays, texts, and performances from the contemporary European repertoire, this study will consider dramatic representation as an anthropological fact involving practices of signs and interpretation, through the prism of the investigation – understood as a creation process, a structuring form but also a way of relating to the world and the spectator. A path of hypotheses and a laboratory of the cognitive and heuristic functions of representation, it appears that the investigation refers to this confusion through which theatre is thought to represent something. This dissertation therefore inscribes contemporary dramaturgies within the clue paradigm, coined by C. Ginzburg, in relation to novelistic forms of the investigation (naturalistic and detective novels). Thus it intends to repair the theoretical deficit plaguing this “master fiction” (D. Kalifa), opening a reflection on the meanings of reusing a modern approach, tied to the search for meaning and legibility in a time marked by postmodernism and characterized by an attitude of relativism and hermeneutic suspense. The use of scenes of trial, reconstitution, and questioning, studied in the second part, uncovers critical and reflexive operations in which the devices of truth production are questioned as politics and poetics of the sign. As for documentary writing – the focus of the third part, it appears crossed by three distinct orientations – assertive, constatative and interrogative – which will be identified according to their relations to the investigation

In the context of a Conversational Analysis approach ethnographically oriented, my work deals withcoordination in the telephonic interaction of calls made to the French medical emergency call («15»). Two aspects of this coordination are explored : (1) organization of the questioning in the following ternary sequential format « Question-Answer-Acknowledgement » ; (2) coordination between the production of these ternary sequential formats and their interaction with the computerized system.This research is based on audio-visual data gathered at the Center of Reception and Regulation of Calls (in French : CRRA) of the SAMU of Versailles (France).The first aspect of the coordination (1) proposes an analysis of the various actions accomplished through an « OK » ( « d’accord », or its equivalent) which is itself the result of a question put to a caller (fireman, ambulance staff or a private individual) by the CRRA call takers ( »permanencière » in French). This response after an answer presents a wealth of prospective and retrospective features, in terms of the work performed by the participants to obtain and gather informations about a medical problem, to ensure coordination in order to advance step-by-step, to investigate further, to infer, and to establish transitions in the interaction.The second aspect of the coordination (2) illustrates the complexity of the activities of the CCRA staff who must, in a synchronized manner, be engaged in an exchange of a conversational nature, and at the same time organize the gathering of information on the medical problem, while using objects such as a computer mouse, a keyboard, notebooks

Deux facteurs permettent d’augmenter la performance de détection du mensonge : (a)identifier les croyances erronées et lutter contre elles et (b) accroître les différences decomportements entre les menteurs et les personnes qui disent la vérité. Ce travail de thèse aétudié ces facteurs en lien avec les expressions faciales du mensonge. Pour ce faire, nous avonsinvestigué les croyances via l’utilisation d’un questionnaire photographique et utilisé un récitantéchronologique (narration à rebours) pour amplifier les différences de comportements(approche de la charge cognitive).Notre démarche expérimentale a questionné : (a) Les croyances les plus prégnantesrelatives aux expressions faciales du mensonge. (b) L’influence de l’expérience professionnelle,de l’enjeu du mensonge (grave ou anodin) et du comportement mensonger évalué (le sien oucelui d’autrui). (c) La pertinence de l’intensité des expressions faciales pour déceler lesmensonges lors d’un récit antéchronologique.L’ensemble de nos résultats ont mis au jour de nombreuses nouvelles croyances. Septd’entre elles étaient très partagées par les individus et cohérentes avec la vision stéréotypée dumenteur. L’expérience professionnelle, l’enjeu du mensonge et le comportement mensongerévalué ont peu modifié les croyances. Le récit antéchronologique a amplifié les différences entrementeurs et sincères ; et l’intensité des mouvements faciaux a été une mesure pertinente pourdéceler le mensonge. L’application de nos travaux est discutée
Two factors increase the lie detection performance: (a) identify and decrease false beliefsand (b) increase behavioral differences between liars and truth-tellers. These factors were studiedin relation to facial expressions of deception in this doctoral dissertation.The present work questioned (a) The most important beliefs about facial expressions ofdeception throught the use of a photographic questionnaire (b) The influence of professionalexperience, stakes of lie (serious or trivial) and the lying behavior evaluated (his own or that ofothers) (c) The relevance of facial expressions’ intensity to detect lies in an reverse orderinstruction which was used to magnify behavioral differences (cognitive load approach).Our results highlighted many new beliefs. Seven of them were very shared by people andconsistent with the stereotypical view of the liar. Beliefs were little infuenced by professionalexperience, the stakes of lie and the evaluated behavior. The reverse order instruction amplifieddifferences between liars and truth-tellers; and the intensity of facial movements was a relevantmeasure for detecting deception.

Abstract:

Spectrally-based fiber optic sensors are a rapidly maturing technology capable of sensing several environmental parameters in environments that are unfitting to electrical sensors. However, the sensor interrogation systems for this type of sensors are not yet fit to replace conventional sensor systems. They lack the speed, compact size, and usability necessary to move into mainstream test and measurement. The Fiber Sensor Integrated Monitor (FSIM) technology leverages rapid optical components and parallel hardware architecture to move these sensors across the research threshold into greater mainstream use. By dramatically increasing speed, shrinking size, and targeting an interface that can be used in large-scale industrial interrogation systems, spectrally-based fiber optic sensors can now find more widespread use in both research labs and industrial applications. The technology developed in this thesis was demonstrated by producing two advanced interrogators: one that was one half the size of commercially available systems, and one that accelerated live spectral capture by one thousand times – both of which were operated by non-developers with little training.

Full text

Abstract:

L’objectif de cette thèse était de fournir des recommandations aux professionnels de la justice pour recueillir la parole des adolescents, population de témoin peu étudiée en laboratoire. Pour cela, cinq études ont été conduites. Les deux premières avaient pour objectif de dresser un état des lieux des pratiques des enquêteurs français. Nous avons observé une spécificité des adolescents, notamment en ce qui concerne le recours aux suggestions d’informations. Celles-ci étaient plus fréquemment faites lorsque l’adolescent venait de développer un propos, ce qui n’était pas le cas avec des mineurs plus jeunes. Cela pourrait signifier des objectifs d’audition différents selon l’âge du mineur (Étude 1). Pourtant, les recommandations internationales déconseillent fortement l’usage des suggestions en raison des biais mémoriels qu’elles peuvent entrainer immédiatement comme de manière différée. Ensuite, nous avons montré que les adolescents sont les plus représentés parmi les mineurs témoins et/ou victimes dans les affaires françaises et qu’ils sont généralement perçus comme menteurs et pudiques par les enquêteurs (Étude 2). Une étude conduite avec des gendarmes formés aux techniques de recueil de la parole des mineurs témoins (vs. non formés ; Étude 3) a montré que ces utilisations des questions suggestives seraient dues à une croyance des enquêteurs selon laquelle les suggestions pouvaient aider le mineur à se souvenir et à rappeler des informations, mais aussi (et surtout) permettre à l’enquête d’avancer. Ceci était d’autant plus vrai pour les gendarmes non formés. Pour répondre à ces pratiques inappropriées, mais aussi aux besoins des enquêteurs, nous nous sommes intéressés à deux versions modifiées de l’entretien cognitif (ECM). En effet, ce protocole d’audition est basé sur un questionnement ouvert (plutôt que fermé ou suggestif), et propose des stratégies de récupération efficaces. En favorisant la récupération en mémoire et le rappel des informations, il pourrait alors optimiser leur fiabilité, en vue de les exploiter lors de l’enquête judiciaire. Pour cela, nous avons testé la mnémotechnique du Séquençage (Étude 4), qui a montré ses bénéfices. Nous avons en effet observé une hausse du rappel des informations correctes (vs. entretien structuré ; ES). Toutefois, celle-ci s’accompagnait d’une hausse des erreurs. Un résultat similaire a été observé en testant une version raccourcie de l’ECM pour des événements répétés dans le temps (vs. événement unique ; Étude 5). De plus, cette étude a mis en avant une hausse des affabulations avec l’ECM (comparativement à un ES, et indépendamment de la fréquence de l’événement), mais aussi des confusions entre les différents événements visionnés par une partie des adolescents. Ces augmentations des informations erronées n’entrainaient cependant, dans aucune des deux études, de chute du taux d’exactitude. Ces résultats seront discutés au regard de la littérature scientifique, et des recommandations appliquées seront formulées afin d’aider les enquêteurs à conduire au mieux leurs auditions d’adolescents témoins et/ou victimes
The goal of this thesis was to provide recommendations to any practitioner involved in the justice system to interview adolescent witnesses and/or victims, a population little studied in laboratory analogue contexts. To do so, five studies were conducted. The first two studies were aimed at establishing an inventory of the young French investigators’ witness interview practices. We observed that adolescents are a specific population, in particular regarding the use of suggestive questions. This type of questions increased right after the adolescents had just developed a statement, which was not the case with younger children. This result might reveal that, during investigative interviews with children and adolescents, the investigators have different aims depending on the age of the young witness (Study 1). However, international recommendations strongly discourage the use of suggestions because of immediate and delayed memory biases that may occur. Secondly, we have shown that adolescents represent most of the under legal age witnesses and/or victims in French cases, and that investigators generally perceived them as liars and as easily ashamed (Study 2). A study conducted with military police officers who previously had training in the use of structured interview techniques (vs. untrained officers; Study 3) showed that their use of suggestive questions were related to the belief that suggestive prompts could help the young witness and/or victim retrieve and recall information, but also (and most importantly) allow the investigation to move forward. This was especially observed with untrained military police officers. To deal with these inappropriate practices, we investigated the efficiency of two modified versions of the cognitive interview (MCI). This interview protocol is based on an open (rather than closed or suggestive) questioning style, and proposes effective retrieval strategies. Relying on techniques that promote memory retrieval and recall of information, it could then enhance the adolescents’ statements’ reliability, for these to be used during the investigation. We therefore tested a mnemonic called ‘guided peripheral focus’ (Study 4), which showed its benefits. Indeed, we observed an increase in the recall of correct information (vs. structured interview; SI). However, this was accompanied by an increase in errors. A similar pattern was observed with a shortened version of the MCI (vs. SI) used for repeated events (vs. single event; Study 5). In addition, this last study showed an increase in confabulations with the MCI (compared to a SI, and irrespective of the frequency of the event), but also in confusions between the different events experienced by some of the adolescents. However, these increases in erroneous details did not lead to a drop in the accuracy rate in either study. The results of the five studies will be discussed in regards with the scientific literature, and recommendations to help justice practitioners conduct their adolescent witness and/or victim interviews as appropriately as possible will be provided

Full text

Abstract:

En première analyse, misérables et chemineaux apparaissent à l’historien comme des figures typiques de toute société. En fait, en dehors des caractéristiques du régime politique, ils exigent le même genre d’attitude et des mesures, de sorte que les critères normatifs réglementaires semblent identiques de tout temps. La question préliminaire est alors de savoir si certaines situations, ou conditions d’incertitude ou doute sur le statut juridique des personnes sont ou non indépendantes de leur qualification administrative et ainsi du type d’ordre social ou du régime actuel. Cette recherche propose de maintenir ces catégories dans deux formes de justice pour les pauvres, ayant un rôle de liaison dans la construction d’une affaire pénale/politique, depuis l’apparition des circonscriptions administratives de la Vénétie napoléonienne. Les réactions face à des manifestations de pauvreté sont notées surtout et avant tout d’une certaine prudence, plutôt que par la solidarité et les secours. C’est le signal d’une attitude spécifique réservée à la conduite de l’indigence. L’analyse de l’expérience dans un contexte local nous permet aussi de reconstituer la signification pratique d’une situation en termes juridiques ou sociaux. Ce qui démontre comment ces catégories conceptuelles sont les plus largement utilisées dans le schéma d’un discours à un niveau plus élevé de généralisation, qui peut être opérationnel en appliquant à la situation historique ces régimes normatifs réglementaires. L’objectif est également de comprendre comment les catégories influencent le processus de construction identitaire, non seulement en attribuant à chaque personne un rôle avec différents droits, obligations et pouvoirs, mais en soulignant également cette condition à chaque instant de la vie. Il s’agit aussi de tracer un profil juridique et social des misérables et des chemineaux, à partir de l’exploration de la documentation produite par l’administration de certains centres de pouvoir au début du XIXe siècle. L’objectif est de comprendre comment certaines catégories réapparaissent de manière systématique dans le droit codifié ou étatique et de quelle manière ces dernières sont employées dans l’administration
At first sight, miserables and wanderings arise to the historian as common examples of any society. Indeed, besides the characteristics of the political system, they require the same approach and measures, whereas the normative/statutory standards appeared identical at all times. The threshold question is then whether specific administrative situations, under ambiguity or else doubtfulness on the legal status of the people, are independent of their qualifications and thereby social order or current system. This research proposes to retain these categories in two different forms of justice for indigenous, having a liaison function in the construction of a political criminal proceeding later the onset of districts in Venetia during the Napoleonic period. The reaction to the worst forms of poorness scored foremost a significant prudent manner rather than substantive support for the others. It’s the signal to be fixed being in a specific common attitude relative to the private management policy of indigence care. The frame analysis in local context also allows us to reconstruct the legal and extralegal social means in the hands-on situation. I want to show how these categories are most widely produced in the plan of higher level rhetorical justification, which can be made available in the historical application of this normative/statutory standards. The goal is to know how the categories affect the process of identity building, not just by awarding to each person a social role and various rights, duties and power, and also by highlighting this social condition in everyday life. It is also necessary to set a normative and social profile, based on administrative materials produced by a management policy in the early 19th century. The expected outcome is to understand how various sorts are systematically denied to people in statute law, and how these standards work in administrative activities

Abstract:

Cette thèse s’intéresse à un dispositif, particulièrement critiqué à la fin des années 2000 pour son usage exponentiel et pour son indigence en matière de droits : la garde à vue. Loin de la restreindre à sa codification juridique d’acte d’enquête, la garde à vue peut alors être appréhendée comme un instrument désormais privilégié de gestion de la police et de la politique en matière de petite et moyenne délinquance. Mais sous le coup des injonctions européennes, le gouvernement français est contraint de la réformer en avril 2011. Le mis en cause a désormais le droit d’être assisté d’un avocat pendant toute la durée de l’interrogatoire. Avec cette réforme, la garde à vue incarne une tension entre, d’une part, l’intensification de la répression de certaines populations et d’autre part, la reconnaissance de droits nouveaux qui leur sont accordés. À partir d’une enquête mêlant études de débat, ethnographie et questionnaire, l’objet de cette thèse est d’interroger la mise en œuvre et les effets de cette réforme paradoxale sur l’institution policière. La réforme de la garde à vue ne peut pas être appréhendée comme une simple modalité d’action publique. Elle constitue un moment critique de transformation des modalités de relations de l’État aux administrés, complexifiées par l’introduction des avocats en interrogatoire. Les effets de la présence de l’avocat varient, selon les usages qui sont faits de la garde à vue (d’une mesure de contention à un acte d’enquête), liés à la position des agents et des services dans la hiérarchie des prestiges policiers, et selon les propriétés sociales des gardés à vue, des policiers, et des avocats. La rencontre des uns et des autres peut prendre la forme d’une configuration d’alliance, de conflit, de concurrence, selon les différentes variables étudiées. Par l’étude de ces configurations d’interrogatoires, situées et incarnées, nous montrons qu’à chaque type de population est attaché un usage spécifique de la garde à vue. Ainsi, l’entrée par la garde à vue permet plus largement de voir la justice et la gestion des illégalismes par l’État en train de se faire
This PhD investigates an apparatus that attracted considerable criticism in the late 2000s for being overused and failing to ensure enough rights: garde à vue, which roughly translates as police custody. Far from being only an investigative act, as its legal definition goes, garde à vue increasingly operates as a key instrument for the police and political management of petty crime. To meet the EU’s demands, however, the French government was forced to reform the system in April 2011. Suspects now have the right to receive a lawyer’s assistance during their entire interrogation. The reform of garde à vue reflects a tension between the intensifying repression of specific populations and the recognition of new rights granted to them. Drawing on the study of debates, ethnographic material and a questionnaire, this research examines the implementation and the effects of this paradoxical reform on the police institution.The reform of garde à vue cannot be approached simply as a public policy shift. Beyond that, it constitutes a key juncture in the transformations of the relationships between the State and citizens resulting from the introduction of lawyers during the interrogations. Effects of the lawyer’s presence vary according to the uses of garde à vue (from a measure of restraint to an investigative act), which relate to the position of agents and departments in the hierarchy of police prestige, and the social properties of suspects, members of the police and lawyers. The interactions between these protagonists may be characterized by configurations of alliance, conflict or competition depending on the above variables. Through the situated, embodied analysis of these configurations of interrogation, I show that a distinct use of garde à vue corresponds to each type of population. The focus on police custody ultimately yields broader insights into justice and the State’s management of illegalisms in the making

Normally, discussions about suspects’ confession evidence in Taiwan focus on legal aspects, only rarely do they probe the process and reasons that underlie the confession from an operational point of view. Yet confessions are important to clarify details of the case and shorten the time of investigation. This thesis analyzes, from the viewpoints of investigators and prisoners, what kind of interrogational techniques, personality variables and situational factors would help produce appropriate confessions. According to previous published research, three major factors are generalized in the thesis: interrogator, suspect, and situation. Factors relating to the interrogator include five parts: the preparation before investigations, interrogational techniques, judgment of the interrogators, disposition of the investigation rooms and personalities of the interrogators; as for the factors about suspect, memory, cognition, and emotion are included; situational factors involve strength of the evidence, opinions of defense counsel, length of the legally prison term, detainment, and the importance of a third person. A questionnaire was constructed, according to the above-mentioned factors. A sample of investigators (n=389) and prisoners (n=26) completed the questionnaire. Finally, information about the questionnaires was compiled and encoded; analyzed using T test, ANOVA, and regression analysis by SPSS. The study found that the basic of approach on confessions is to seek to obtain the suspects’ trust, with investigators stressing the personalities of interrogators and the interrogational techniques, convicts care more about personal feelings, and both sides agreed that factors such as the illegal interests, illegal methods and high celebrity rating of the suspect are unfavorable to obtain a confession. Additionally, investigator’s age, seniority, work area, and frequency of obtaining a confession and convict’s age will influence their grades of the questionnaire. According to the regression analysis, investigator’s age, and major in college and factor of interrogator are more influential to the success of obtaining a confession. In the light of these results, the thesis suggests that interrogation should be assigned to particular people, and role-playing via on-the-job training should be reinforced. As for further research, the work reported here would be increased by improving the questionnaire, increasing the sample size, analyzing video tapes of interrogations and distinguishing how different kinds of criminal react to interrogation.

Abstract:

A confession in a criminal investigation is a prosecution’s most potent weapon and is sometimes the best available evidence. Identifying the profile of an effective interrogator may improve interview performance and personnel selection. Data concerning personality, interviewing competency, and communicative suspicion was collected from 29 police interrogators employed with large police forces across Canada. Interrogators reported on the outcome of their interrogations of suspects over a six-month period. It was expected that interrogators who obtain a positive outcome (full confession, partial admission, cleared innocent) would likely score high on four of the five factors of the NEO-PI, but low on N; would tend to score high on all dimensions of the competency scale (C-T, CNR, DI and Co), except for the Be scale; and would score moderately on the communicative suspiciousness measure. Results indicated a significant but inverse relationship between interrogation outcome and two pairs of variables: Conscientiousness and Careful-Tenacious, and Extroversion and Careful-Tenacious, each accounting for nearly 25% of the variance. A suppression effect is present. The knowledge gained from this experiment will assist police forces in Canada with the identification and selection process of two main groups of police officers, investigators who are called upon to interrogate persons suspected of having committed serious criminal activities and polygraph operators.

This thesis shows that we develop a remote fiber monitoring system by using a remote monitoring software in a FBG interrogation system. The system is potential to replace the optical measuring instrument because it is cheaper in the market. On the other hand, the system synchronize large-scale and multi-viaduct bridge security with real-time monitoring to protect people's safety. After the experiment, we choose the “broadband light source pass through tunable filter type probe light source” in the FBG interrogation system. Because it has the best stability after putting it in the room temperature environment for 8 hours. In this structure, the absorption at 1530 nm of Erbium-doped fiber is 17.5 dB/m and the length is 5 m. The channel of Optoplex's C-band tunable filter is fixed at the middle (M4400) of C-band when the output peak wavelength is stable at 1547.201 nm without any fluttering phenomenon; while the maximum peak power is -24.06 dBm and the minimum is -24.10 dBm. The variation is very stable and the range is only ± 0.02 dB. The wavelength range for scan monitoring is from 1527.996 nm to 1563.029 nm developed in the FBG interrogation system and it contains the whole C-band wavelength. In the remote monitoring software, the initial value of interrogator setting function, single fiber grating scanning function, all bridges automatic monitoring function and resolution/span setting function can all work after the hardware and software integration test. Users are able to control the FBG interrogation system, read the monitoring results and analyze the data with remote monitoring software at a long distance. At last, the vertical stress monitoring experiment is carried out by the remote optical fiber monitoring system. It’s the actual simulation of real-time monitoring. We selected three fiber gratings laid out at different analog bridges and at different distances to do the experiment. The results show that the sensitivity of FBG1-2, FBG2-4 and FBG3-1 for the vertical force is 61.22 pm/N, 61.22 pm/N and 110.2 pm/N and for the linearity R2 is 0.999, 0.999 and 0.9922. In order to ensure the reliability and accuracy of this monitoring system, this chapter performs reproducibility testing. The results are just the same as the ones in the first testing. Besides, we applied 0.98 N vertical force on the selected fiber grating and put it at room temperature for 8 hours to test the stability of the FBG reflection wavelength and the peak power of this surveillance system. The results show that the reflection wavelength is very stable without any fluttering phenomenon. There are only few datum showing the drifting between ±0.1 dB. This monitoring system monitors the signal that shows a fairly stable state at the sensing ends as well as at different distances of the three analog bridges.

This thesis presents a remote fiber monitoring system. A fiber Bragg grating (FBG) interrogation system with remote monitoring software is developed to replace the high-cost optical measuring instruments to ensure livelihood security and immediately monitor several bridges in large scale. Based on the first generation of the FBG interrogation system proposed by our laboratory, we present herein the second generation interrogation system to replace the optical tunable filter. With a mini-second tuning speed, the real-time monitoring, which is the most important characteristics, is more suitable in bridge monitoring system. Moreover, we downsize the FBG interrogation to make our system portable. Regarding the second generation FBG interrogation system, the wavelength measurement can range from 1527 nm to 1567 nm (include the entire C band) and the speed of scanning reaches 20 mini-second/point. While testing the remote monitoring software, including setting initial values, scanning single FBG, automatically monitoring bridges and data automatically saved, all the functions work perfectly. Thus, users can control and analyze the data by using the monitoring software. Finally, we use the remote fiber monitoring system to measure the FBG settlement sensor that is applied to the bridge sensing to simulate the function of real-time monitoring. The experiment is set up at different distances with three settlement sensors. The results show that the sensitivity of the changing in water level of the settlement sensor 1, 2 and 3 are 0.1543 nm/cm, 0.1536 nm/cm and 0.155 nm/cm, respectively, with the linearity R2 is 0.9968, 0.9995 and 0.9988. In addition, the height we manually changed is used to simulate how the height changes on one single point or multi-points. Further, the stability of the reflected wavelength and the peak power of each settlement sensors are tested in this thesis. It is shown that the reflected wavelength is stable with slightly fluctuation caused by thermal drift. Here, we have reached a peak power of less than ±0.1 dB jitter. To sum up, the system receives a stable signal when monitoring the three settlement sensors with three different distances.

Abstract:

The thesis describes development and application of coupled resonant coil sensors, which is of growing interest for remote monitoring applications. An interrogation technique, which improves the accuracy and interrogation range of coupled resonant coil sensors, is introduced. The method uses time-domain gating to produce measurements that are dominated by the response of the sensor coil and are immune to surrounding object interference. For application in structural health monitoring a low cost embeddable coupled coil sensor, which is able to monitor the corrosion potential of reinforcement steel is presented. Results of an accelerated corrosion test using the sensor indicate that corrosion potential can be monitored with a resolution less than 10 mV and a sensitivity of 0.76 kHz/mV. The last part describes a coupled-coil pH sensor based on pH electrode potential measurement. A linear response over a 4 to 10 pH dynamic range and 50 kHz/pH sensitivity are achieved with a 0.1 pH resolution and 30 s response time.

Le présent mémoire cherche à déterminer s’il existe des facteurs qui conduisent aux aveux chez les agresseurs sexuels durant un interrogatoire. Dans ce but, notre étude est basée sur 183 dossiers d’agression sexuelle traités par le Service de police de la Ville de Montréal. Les 137 participants qui ont fait une ou deux victimes (un dossier par victime) étaient âgés de 15 à 71 ans au moment du crime, et sont majoritairement francophones, caucasien et sans emploi. Toutes les variables sélectionnées ont été divisées en trois catégories : les caractéristiques de l’agresseur, les caractéristiques du crime et les caractéristiques contextuelles de l’interrogatoire. Les agresseurs sexuels qui ont avoué leur crime avaient les caractéristiques suivantes : caucasien, célibataire, n’ayant pas utilisé la menace ni causé de blessures, la victime était un garçon ou une femme adulte. Il n’y avait, contre eux, ni preuves matérielles ou biologiques, ni présence de sperme sur la victime, et il n’y a pas eu de séance d’identification. De plus, ils ont subi plusieurs interrogatoires, souvent dans un bureau privé en présence d’un seul interrogateur, qui n’est pas l’enquêteur principal, mais ils ont écrit et signé leur déclaration. Ces résultats devraient aider les policiers à cibler les facteurs les plus favorables aux aveux tout en montrant qu’il s’agit généralement d’un ensemble de facteurs qui conduisent les agresseurs sexuels aux aveux lors d’un interrogatoire.
This study seeks to determine whether there are factors that lead to the confession in sex offenders, during an interrogation. For this purpose, the study is based on 183 cases of sexual abuse handled by the Service de police de la Ville de Montréal. The 137 participants who made one or two victims (one file for each victim) were aged from 15 to 71 years old at the time of crime, and are mostly French-speaking, Caucasians and unemployed. All selected variables were divided into three categories: characteristics of the sex offender, characteristics of the crime and characteristics of the context of the interviews. Sex offenders who have confessed their crime had the following characteristics: Caucasian, unmarried, who did not use threat, who did not commit injuries and their victim was a young male or an adult female. Against them, there were no physical evidence, nor biological evidence, nor the presence of semen on the victim, and there was no identification parade. In addition, they have had several interviews, often in a private office with a single interrogator who isn’t the principal inspector, but they wrote and signed their statement. These results should help the police to identify the factors most favorable to confession, showing that it’s usually a combination of factors that lead sex offenders to confession during an interrogation.

Abstract:

Les chercheurs s’étant penchés sur les facteurs influençant la décision du suspect de confesser son crime ont mis en évidence que deux facteurs sont principalement influents : la force de la preuve (Des Lauriers-Varin et St-Yves, 2006; Moston et al., 1992) et la conduite de l’enquêteur (Holmberg et Christianson, 2002; Kebell et al., 2005). Par contre, les contradictions entre ces études ont apporté davantage de confusion que de réponses à la pratique. Cette étude vise donc à explorer l’incidence de ces deux facteurs sur l’inclination du suspect à confesser son crime et les possibles interactions entre eux. Pour ce faire, 50 enregistrements vidéo d’interrogatoires d’homicide furent visionnés et les données furent soumises à des analyses statistiques et qualitatives. Les résultats d’une régression logistique démontrent que la conduite de l’enquêteur est le facteur prédominant pour prédire l’obtention d’aveux du suspect en contrôlant pour l’effet des variables statiques et de la preuve. Également, les résultats mettent en évidence qu’en augmentant les attitudes et comportements associés à une conduite « positive », l’enquêteur augmentait les probabilités d’aveux du suspect. De plus, les résultats indiquent que l’augmentation du nombre d’éléments de preuves est associée à une plus grande démonstration de « rapport de force » de la part de l’enquêteur. Les résultats sont discutés en relation à l’effet des principaux facteurs sur les schémas et dynamiques prenant place entre l’enquêteur et le suspect.
The studiess on factors influencing a suspect’s decision to confess his crime during a police questioning, reveal that the strength of evidence (Moston et al., 1992 and Des Lauriers-Varin and St-Yves, 2006) and the detective’s behaviour (Holmberg et Christianson, 2002 et Kebell et al., 2005) are considered key factors. However, past studies show notable contradictions. The present work focuses on the role of the two aforementioned factors, in the suspect’s decision to confess a crime and the potential interaction effect among them. The data were obtained by visioning and analyzing 50 questionings of a suspect linked to a homicide investigation. The logistic regression’s results show that the detective’s behaviour is the predominant factor in obtaining a confession from a suspect. Theses results are maintained when both the characteristic of the suspect and the weight of evidence are controlled for. Moreover, our results suggest that a “positive” attitude from the detective’s part is associated with a greater propensity toward confessing. Also, the results indicate that the greater available evidence to support the case, will translate into more “dominant” style of questioning from the detectives. The results are discussed in relation to the effects of the different dynamics taking place between the detective and the suspect during the questioning.
