Die Dissertation behandelt die Zusammenhänge zwischen den beiden einflußreichsten neueren Theorien über die Logik von Konditionalsätzen: der auf die Mögliche-Welten-Semantik zurückgreifenden, primär für konjunktivische Konditionalsätze entwickelten Theorie von David Lewis und derjenigen von Ernest Adams, die primär für indikativische konzipiert wurde und in der Tradition des Bayesianismus steht. Bei dem Versuch, beide Theorien auf den indikativischen Bereich anzuwenden, erwiesen sich die Lewisschen Trivialitätstheoreme als schwerwiegendes Problem. Die wichtigsten der in der Literatur vorgeschlagenen Lösungsansätze (z.B. diejenigen von V. McGee, B. v. Fraassen und F. Jackson) werden in der Dissertation ausführlich erörtert und als unbefriedigend zurückgewiesen. In diesem Kontext findet auch eine Diskussion von McGees Kritik an der generellen Gültigkeit des Modus-ponens-Prinzips statt. Anschließend wird dargelegt, warum Adams´ Versuch, seine Analyse auf konjunktivische Konditionalsätze anzuwenden, scheitert und daß aus sehr ähnlichen Gründen die kausale Entscheidungstheorie von A. Gibbard und W. L. Harper in ihrer gegenwärtigen Form zu Widersprüchen führt. Der Schlußteil der Arbeit zeigt, daß sich die Zuständigkeiten der beiden Theorien nur auf der Grundlage einer neuen Klassifikation angemessen bestimmen lassen. Die übliche Indikativ/Konjunktiv-Dichotomie muß durch eine auf kontextuelle Kriterien rekurrierende Unterscheidung im Bereich der indikativischen Konditionalsätze in eine Trichotomie überführt werden. Es wird nachgewiesen, daß unter weithin akzeptierten Voraussetzungen zu einer der drei Teilklassen nur solche Sätze gehören, die nicht im selben Sinne wie andere Aussagesätze wahr oder falsch sein können.

This thesis focuses on fictious librarians in film. It uses three research questions: Firstly, how the movies make use of typical elements from movie genres and narrative modes in their portrayal of library work and librarians. Secondly, the way in which myths, stereotypes and ideas surrounding librarians and library work are used – typically or atypically – to build librarian characters and the narrative. Thirdly and lastly, it discusses the protagonists, focusing on their personalities and character arcs in relation to their role as librarians. The theoretical background departs partly in discourse surrounding librarian imagery in general, but also in film genre and mode theories. The thesis consists of two case studies, each focusing on one film, both with librarian protagonists. Even though this thesis focuses on them, the other librarian roles are also discussed, as well as the dynamics of the librarian teams. The two films discussed in this thesis are vastly different. One, Grabben i graven bredvid (2002), is a romantic relationship film with a female public librarian as protagonist, and the other, Bibliotekstjuven (2011), is a dark drama about a male research librarian turned book thief. Both films tie librarian myths to genre patterns: the single yet snotty female librarian is well fit as a romantic lead, and the male librarian as a pale, mysterious underdog makes a great villain protagonist. However, the films also present common themes and traits. Both librarian protagonists display elitism in relation to their professional identity, at the expense of their non-librarian partners. I argue that this is rooted in the historical idea of the librarian as a judgemental snob, but also that of librarians as ambiguous (and possibly false) “guardians” of the treasures of the library. Both librarian protagonists studied here lead double lives in one sense or another – most obvioulsy the book thief in Bibliotekstjuven, but also the confused female librarian in Grabben i graven bredvid who tries to hide her infatuation with a farmer from her colleagues. Some other results concern the use of the library as idea in relation to genre and mode elements. I argue, for example, that the Royal Library of Sweden in different stages of the narrative in Bibli- otekstjuven is not only a crime scene but also plays the part of a betrayed lover. This of course is connected to the societal role of libraries, in particular the relationship between “ordinary people” and libraries - a central theme in both films. One ends in a healing of a historic wound between a working man and an educated woman through love, while the other, in fact, ends in melodrama when the crime of stealing books is punished by death, yet also forgiven in an ideological sense given the protagonists humble beginnings and desperation. To conclude, both films thematise ideas surrounding personal morals, truth, social status and social justice, and do so through struggling librarian protagonists. Both films take place in worlds with a dual structure, where the fine world (represented by libraries) collides with the mundane, and the librarian protagonists try to navigate. Both films, finally, use librarian stereotypes to build the narratives – but they do not, apart from in a few scenes, reproduce them. This is a two years master’s thesis in library and information science.

Le but de la présente étude est de mieux comprendre le mode opératoire des entraîneurs ayant commis des abus sexuels en contexte sportif. Pour ce faire, le premier objectif est de décrire les stratégies précisément utilisées comme mode opératoire par les entraîneurs. Quant au second objectif, il vise à décrire l'influence de certains facteurs individuels et situationnels (sexe de la victime, niveau sportif et année du premier abus sexuel commis par l'entraîneur) sur les stratégies employées par les entraîneurs pour commettre les abus. Une grille de codification a été développée en se basant sur des travaux en sciences du sport et en criminologie portant sur les abus sexuels et le mode opératoire. Cette dernière a servi d'outil pour identifier les données pertinentes à l'étude comprises dans des jugements de Cour et des articles journalistiques au sujet de 120 entraîneurs ayant commis des abus sexuels en contexte sportif. Des analyses descriptives ainsi que des chi carrés ont été effectuées pour décrire les stratégies du mode opératoire des entraîneurs et pour déterminer s'il existe une association statistique entre certaines stratégies du mode opératoire et certaines variables individuelles et contextuelles. Les résultats montrent qu'en général, les entraîneurs gagnent la confiance de l'athlète en devenant ami avec celui-ci, n'emploient pas de stratégies pour exercer un contrôle ou développer une dépendance, emmènent l'athlète dans des endroits isolés autres que sur les lieux d'entraînement et à leur domicile, passent graduellement de touchers non sexuels à des touchers sexuels et n'emploient pas de stratégies en particulier par maintenir le silence. Les entraîneurs qui commettent des abus sexuels à l'endroit d'athlètes féminines emploient davantage des stratégies en lien avec la séduction (p. ex., déclaration d'amour) alors que ceux qui commettent ces gestes à l'égard de victimes masculines profitent du sommeil de l'athlète ou intègrent les abus pendant un jeu. Les entraîneurs de niveaux élites sont plus susceptibles d'employer des stratégies pour exercer un contrôle et développer une dépendance que ceux de niveaux non-élites. Les résultats indiquent aussi qu'un certain changement de stratégie semble s'être effectué avec le temps : les entraîneurs ayant commis leur premier abus avant 2000 ont attendu de passer une nuit avec leur athlète dans le but de l'isoler. Ceux ayant commis leur premier abus en 2000 ou après avaient davantage échangé du matériel sexuellement explicite avec leur athlète. Il s'agit de la première étude qui fournit des données sur les stratégies précisément employées par plusieurs entraîneurs pendant toutes les étapes des abus et qui montre que le sexe de la victime, le niveau sportif et l'année au premier abus sexuel ont une influence sur ces stratégies. / The purpose of this study is to explore the modus operandi of coaches who have committed sexual abuse in sport settings. The first objective is to describe the specific modus operandi strategies used by coaches. The second objective is to describe the influence of specific individual and situational factors (gender of the victim, sport level and year of the first sexual abuse committed by the coach) on the strategies used to commit the abuse. A coding grid was developed based on previous work in sport sciences and criminology on sexual abuse and modus operandi. This was used as a tool to identify data relevant to the study from court judgments and newspaper articles about 120 coaches who had committed sexual abuse in sport. Descriptive and chi-square analyses were conducted to describe the coaches' modus operandi strategies and to determine if there were statistical associations between modus operandi strategies and certain individual and contextual variables. Results showed that coaches generally gained the athlete's trust by becoming friends with the athlete, did not employ strategies to exert control or develop dependency, took the athlete to isolated locations other than training sites and their homes, gradually moved from non-sexual to sexual touching, and did not employ any strategies to maintain silence. Strategies related to seduction (e.g., declarations of love), were more frequently used by coaches who sexually abuse female athletes while strategies such as taking advantage of the athlete's sleep or incorporating the abuse into a game were more likely to be used by those who sexually abused male victims. Strategies to exert control and develop dependency were statistically associated with elite coaches. Coaches who perpetrated their first offence in 2000 or later were more likely to have exchanged sexually explicit material with their athlete. This is the first study to provide data on the specific strategies employed by multiple coaches during all stages of abuse and to demonstrate the influence of victims' gender, sport level, and year of first sexual abuse on these strategies.

Positron emission tomography (PET) is a well-established functional imaging method used in nuclear medicine. It allows for retrieving information about biochemical and physiological processes in vivo. The currently possible spatial resolution of PET is about 5 mm for brain acquisitions and about 8 mm for whole-body acquisitions, while recent improvements in image reconstruction point to a resolution of 2 mm in the near future. Typical acquisition times range from minutes to hours due to the low signal-to-noise ratio of the measuring principle, as well as due to the monitoring of the metabolism of the patient over a certain time. Therefore, patient motion increasingly limits the possible spatial resolution of PET. In addition, patient immobilisations are only of limited benefit in this context. Thus, patient motion leads to a relevant resolution degradation and incorrect quantification of metabolic parameters. The present work describes the utilisation of a novel motion compensation method for clinical brain PET acquisitions. By using an external motion tracking system, information about the head motion of a patient is continuously acquired during a PET acquisition. Based on the motion information, a newly developed event-based motion compensation algorithm performs spatial transformations of all registered coincidence events, thus utilising the raw data of a PET system - the so-called `list-mode´ data. For routine acquisition of this raw data, methods have been developed which allow for the first time to acquire list-mode data from an ECAT Exact HR+ PET scanner within an acceptable time frame. Furthermore, methods for acquiring the patient motion in clinical routine and methods for an automatic analysis of the registered motion have been developed. For the clinical integration of the aforementioned motion compensation approach, the development of additional methods (e.g. graphical user interfaces) was also part of this work. After development, optimisation and integration of the event-based motion compensation in clinical use, analyses with example data sets have been performed. Noticeable changes could be demonstrated by analysis of the qualitative and quantitative effects after the motion compensation. From a qualitative point of view, image artefacts have been eliminated, while quantitatively, the results of a tracer kinetics analysis of a FDOPA acquisition showed relevant changes in the R0k3 rates of an irreversible reference tissue two compartment model. Thus, it could be shown that an integration of a motion compensation method which is based on the utilisation of the raw data of a PET scanner, as well as the use of an external motion tracking system, is not only reasonable and possible for clinical use, but also shows relevant qualitative and quantitative improvement in PET imaging. / Die Positronen-Emissions-Tomographie (PET) ist ein in der Nuklearmedizin etabliertes funktionelles Schnittbildverfahren, das es erlaubt Informationen über biochemische und physiologische Prozesse in vivo zu erhalten. Die derzeit erreichbare räumliche Auflösung des Verfahrens beträgt etwa 5 mm für Hirnaufnahmen und etwa 8 mm für Ganzkörperaufnahmen, wobei erste verbesserte Bildrekonstruktionsverfahren eine Machbarkeit von 2 mm Auflösung in Zukunft möglich erscheinen lassen. Durch das geringe Signal/Rausch-Verhältnis des Messverfahrens, aber auch durch die Tatsache, dass der Stoffwechsel des Patienten über einen längeren Zeitraum betrachtet wird, betragen typische PET-Aufnahmezeiten mehrere Minuten bis Stunden. Dies hat zur Folge, dass Patientenbewegungen zunehmend die erreichbare räumliche Auflösung dieses Schnittbildverfahrens limitieren. Eine Immobilisierung des Patienten zur Reduzierung dieser Effekte ist hierbei nur bedingt hilfreich. Es kommt daher zu einer relevanten Auflösungsverschlechterung sowie zu einer Verfälschung der quantifizierten Stoffwechselparameter. Die vorliegende Arbeit beschreibt die Nutzbarmachung eines neuartigen Bewegungskorrekturverfahrens für klinische PET-Hirnaufnahmen. Mittels eines externen Bewegungsverfolgungssystems wird während einer PET-Untersuchung kontinuierlich die Kopfbewegung des Patienten registriert. Anhand dieser Bewegungsdaten führt ein neu entwickelter event-basierter Bewegungskorrekturalgorithmus eine räumliche Korrektur aller registrierten Koinzidenzereignisse aus und nutzt somit die als "List-Mode" bekannten Rohdaten eines PET Systems. Für die Akquisition dieser Daten wurden eigens Methoden entwickelt, die es erstmals erlauben, diese Rohdaten von einem ECAT Exact HR+ PET Scanner innerhalb eines akzeptablen Zeitraumes zu erhalten. Des Weiteren wurden Methoden für die klinische Akquisition der Bewegungsdaten sowie für die automatische Auswertung dieser Daten entwickelt. Ebenfalls Teil der Arbeit waren die Entwicklung von Methoden zur Integration in die klinische Routine (z.B. graphische Nutzeroberflächen). Nach der Entwicklung, Optimierung und Integration der event-basierten Bewegungskorrektur für die klinische Nutzung wurden Analysen anhand von Beispieldatensätzen vorgenommen. Es zeigten sich bei der Auswertung sowohl der qualitativen als auch der quantitativen Effekte deutliche Änderungen. In qualitativer Hinsicht wurden Bildartefakte eliminiert; bei der quantitativen Auswertung einer FDOPA Messung zeigte sich eine revelante Änderung der R0k3 Einstromraten eines irreversiblen Zweikompartment-Modells mit Referenzgewebe. Es konnte somit gezeigt werden, dass eine Integration einer Bewegungskorrektur unter Zuhilfenahme der Rohdaten eines PET Systems sowie unter Nutzung eines externen Verfolgungssystems nicht nur sinnvoll und in der klinischen Routine machbar ist, sondern auch zu maßgeblichen qualitativen und quantitativen Verbesserungen in der PET-Bildgebung beitragen kann.

In this research docket analysis is evaluated as an investigative tool in stranger rape cases. Owing to the fact that serial rapists mostly reside within the category of stranger rape cases, the researcher attempted to test the value of docket analysis in the identification of patterns and similarities among such cases which could be indicative of serial rape activity. A rape matrix was used as a docket analysis tool to analyse the content of 184 stranger rape cases which was closed as ‘undetected’. In addition to investigative shortcomings in the case dockets, the researcher identified 15 stranger rape cases which presented six unique patterns among them. These identified patterns could be indicative of serial rape activity. / Criminology / M.Tech. (Forensic Investigation)

This study was conducted with the aim to critically analyse how the crime of human trafficking for sexual exploitation can be identified in order to develop practical guidelines to be used during the identification of this crime in South Africa. In this study the researcher conducted a review of pertinent literature, both international and national, to gain an understanding of the problem being researched. The explanatory sequential mixed-method design was used with the main purpose to use the qualitative data to help explain in more detail the initial quantitative results obtained. The explanatory sequential mixed-methods design assisted the researcher to follow a procedure whereby the mixed-mode survey design was applied to collect data through questionnaires. These questionnaires were in the form of mailed, self-administered surveys and in-person interviews with human trafficking provincial coordinators, police officials and investigators of human trafficking within the nine provinces country wide during the first quantitative phase of this study. The data were analysed and followed up during the second qualitative phase with interview schedules that were used in semi-structured one-on-one interviews with the following persons: police investigators working at the SAPS organised crime units who dealt with and investigated cases of human trafficking where victims were trafficked for sexual exploitation; state prosecutors working at the National Prosecuting Authority who dealt with, identified and prosecuted human trafficking cases where victims were trafficked for sexual exploitation in South Africa; NGOs who work in the field of counter-trafficking and victim assistance; and an international police investigator who dealt with, identified and investigated human trafficking cases where victims were trafficked for sexual exploitation. The researcher is of the opinion that this study (analysing how the crime of human trafficking for sexual exploitation can be identified in order to develop practical guidelines to be used during the identification of this crime in South Africa) presents a significant contribution to the identification of human trafficking for sexual exploitation incidents in South Africa and subsequently presents practical guidelines that can be used during the identification of this phenomenon in South Africa. SUMMARY “Modern slavery – be it bonded labour, involuntary servitude, or sexual slavery – is a crime and cannot be tolerated in any culture, community, or country... [It] is an affront to our values and our commitment to human rights.” (US Secretary of State Hillary Rodham Clinton, US Department of State, Trafficking in Persons Report, 2010) This study was conducted with the aim to critically analyse how the crime of human trafficking for sexual exploitation can be identified in order to develop practical guidelines to be used during the identification of this crime in South Africa. In this study the researcher conducted a review of pertinent literature, both international and national, to gain an understanding of the problem being researched. Relevant international legislation which informs South African legislation was accordingly considered in order to explain the current legal framework that forms the foundation to address this problem. A survey was conducted to gain insight into the phenomenon of human trafficking in South Africa. Thereafter interviews were conducted in order to understand the meaning provided by individuals to the problem researched. The researcher also explored how the federal police in Australia address the specific problem relating to the identification and investigation of human trafficking, as they have appointed a leading human trafficking task team focusing on this phenomenon in specific. Links and associations were identified through the knowledge and facts gained in this study, exploring past events and theories developed from former research relating to this topic. This formed the foundation of the study in order to describe and explain future application of findings emanating from this research. The explanatory sequential mixed-method design was used with the main purpose to use the qualitative data to help explain in more detail the initial quantitative results obtained. The explanatory sequential mixed-methods design assisted the researcher to follow a procedure whereby the mixed-mode survey design was applied to collect data through questionnaires. These questionnaires were in the form of mailed, self-administered surveys and in-person interviews with human trafficking provincial coordinators, police officials and investigators of human trafficking within the nine provinces country wide during the first quantitative phase of this study. The data were analysed and followed up during the second qualitative phase with interview schedules that were used in semi-structured one-on-one interviews with the following persons: police investigators working at the SAPS organised crime units who dealt with and investigated cases of human trafficking where victims were trafficked for sexual exploitation; state prosecutors working at the National Prosecuting Authority who dealt with, identified and prosecuted human trafficking cases where victims were trafficked for sexual exploitation in South Africa; NGOs who work in the field of counter-trafficking and victim assistance; and an international police investigator who dealt with, identified and investigated human trafficking cases where victims were trafficked for sexual exploitation. Through a critical analysis of the identification process of the phenomenon of human trafficking for sexual exploitation, the purpose of this research was to gain a better understanding of this phenomenon and establish, develop and provide practical guidelines, procedures and recommendations to the South African Police Service to identify these cases more successfully. The specific research objectives and research questions answered in this study to address the research aim were divided into five categories:  Explore and describe the phenomenon of human trafficking.  Determine the nature and extent of the legal arena to criminalise human trafficking, to prevent human trafficking, and to protect trafficking victims upon which South African legislation is based.  Explain how the identification of the phenomenon of human trafficking fits into the policing process.  Explore the current situation regarding the procedures followed to identify the phenomenon of human trafficking for sexual exploitation.  Develop practical guidelines, procedures and recommendations for police officials to identify human trafficking for sexual exploitation incidents more successfully. The trafficking of women and children for commercial sexual purposes lies in the expansion and ever growing sexual entertainment industry, which is most importantly a demand-driven phenomenon. The exploitation of victims for profit through the use of force, fraud or coercion remains the common denominator of this crime and the trade of human beings continues to evolve into new and more multifaceted forms of exploitation, using debt contracts and other means to coerce people for the purpose of profit gain. Women and children are perceived as the most exploitable and controllable and therefore are deemed to be the most in demand to contribute to this expanding and very competitive economic market driven by maximum profit. It is imperative and fundamental to have an understanding of the trafficking of persons as a crime committed against an individual and therefore it is of the utmost importance that police personnel serving in the South African Police Service (one of the key role players within the Criminal Justice System), are conversant with the means of trafficking, what it constitutes and what attributes and features this phenomenon includes. Through the development of practical guidelines, procedures and recommendations for police officials to identify human trafficking for sexual exploitation incidents more successfully, data obtained from both literature and interviews contributed immensely in the identification of incidents of human trafficking in order to prevent and address this crime successfully. The researcher is of the opinion that this study (analysing how the crime of human trafficking for sexual exploitation can be identified in order to develop practical guidelines to be used during the identification of this crime in South Africa) presents a significant contribution to the identification of human trafficking for sexual exploitation incidents in South Africa and subsequently presents practical guidelines that can be used during the identification of this phenomenon in South Africa. / Police Practice / D.

Text in Afrikaans / In die ondersoek na die modus operandi van die bankrower: 'n kriminologiese introspeksie, kan die ondergemelde drie dimensies onderskei word: Die eerste dimensie is 'n kriminologiese introspeksie wat die betekenis wat bankrowers self aan die uitvoer van bankrooftogte heg, behels. Hierdie leefwereld van die subjekte word deur die navorser "betree" en mede-verken. Doelgerigtheid, morele oorwegings, teesin in geweld, charisma, kognitiewe vermoens en 'n materialistiese ingesteldheid is begrippe wat die bankrower as mens belig. Die tweede dimensie word verteenwoordig deur die begrondingsteorie as navorsingsmetode, gebaseer op die werk van Strauss en Corbin {1990), wat toegepas word ten einde sodanige navorsingsdoelstelling te fasiliteer. Tydens die aanvanklike fase van die ondersoek is daar met 28 bankrowers in aanhoud i ng, gefokusde semi -gest ruktureerde ind i epte-onderhoude gevoer. Opvolgonderhoude is met ses van die 28 subjekte gevoer, met die doel om 'n substantiewe begrondingsteorie te ontplooi, verskille op te klaar en die geldigheid van die data te verhoog. Die derde dimensie reflekteer vervolgens die ontplooiing van 'n substantiewe begrondingsteorie wat weerspieel word in proposisies en wat in vier fases van die modus operandi van die bankrower onderskei word, naamlik die beplanning-; uitvoering-; afhandeling-; en heroorwegingsfase. Elk van die ge'identifiseerde fases word gekenmerk deur progressiewe beweging, natuurlike kontinu'iteit, emosionele belewenisse en 'n individualistiese inslag. Twee kernelemente, naamlik besluitneming en rasionaliteit staan prominent binne die kader van die modus operandi van die bankrower. Die substantiewe begrondingsteorie is daarop ingestel om die verskynsel wat bestudeer word, te verklaar. Seide die oorweging van die ondersoek asook ander doelstellings van die navorser word binne die teorie geakkommodeer. Verdere vergelykende studies kan daartoe bydra om die substantiewe begrondingsteorie te verfyn, te falsifiseer, 6f by gebrek daaraan, tot 'n formele teorie uit te bou. Derhalwe word die begrondingsteorie as navorsingsmetode nie slegs as toepaslik beskou vir toekomstige navorsing oor onderwerpe waaroor daar 'n gebrek aan empiriese bevindinge bestaan en waaroor relatief min kennis in kriminologiese literatuur voorkom nie, maar hou dit ook die voordeel van 'n pluriforme navorsingstudie in. / In the investigation into the modus operandi of the bank robber: a criminological introspection, three dimensions can be distinguished. The first dimension is a criminological introspection comprising the meaning attached by bank rob.bers to the execution of bank robberies. This world of the subjects is entered and co-scouted. Sense of purpose, mora 1 considerations, aversion to violence, charisma, cognitive powers and a materialistic disposition are conceptions that elucidate the bank robber as a human. The second dimension is represented by the grounded theory as research method, based on the work of Strauss and Corbin (1990), which are applied to facilitate such research aims. During the initial phase of the investigation, focused, semi-structured, in-depth interviews were held with 28 bank robbers in detention. Subsequent interviews were held with six of the 28 subjects, aimed at expanding a substantive grounded theory, to clear up differences and to increase the validity of the data. The third dimension reflects the development of a substantive grounded theory which is revealed in propositions and signalised in four phases of the bank robber's modus operandi, namely the planning, execution, disposal and reconsideration phases. Each of these identified phases is characterised by progressive movement, natura 1 continuity, emot i ona 1 experiences and an individualistic infusion. The basic elements, namely decision-making and rationalisation, are prominent in the cadre of the bank robber's modus operandi. The substantive grounded theory is aimed at explaining the study phenomenon. Consideration of the investigation as well as other aims of the researcher are accommodated in the theory. Further comparative studies can assist in refining or falsifying the substantive grounded theory or, failing, to expand it to a formal theory. The grounded theory is therefore regarded as appropriate for future research on subjects about which there is a lack of empirical findings and relatively little knowledge in criminological literature. The theory offers, in addition, the advantage of a pluriform research study. / Sociology / D. Litt et Phil. (Kriminologie)

This thesis is essentially a portfolio of four disjoint yet thematically related articles that deal with some semantic aspect or another of natural language conditionals. The thesis opens with a brief introductory chapter that offers a short yet opinionated historical overview and a theoretical background of several important semantic issues of conditionals. The second chapter then deals with the issue of truth values and conditions of indicative conditionals. So-called Gibbard Phenomenon cases have been used to argue that indicative conditionals construed in terms of the Ramsey Test cannot have truth values. Since that conclusion is somewhat incredible, several alternative options are explored. Finally, a contextualised revision of the Ramsey Test is offered which successfully avoids the threats of the Gibbard Phenomenon. The third chapter deals with the question of where to draw the so-called indicative/ subjunctive line. Natural language conditionals are commonly believed to be of two semantically distinct types: indicative and subjunctive. Although this distinction is central to many semantic analyses of natural conditionals, there seems to be no consensus on the details of its nature. While trying to uncover the grounds for the distinction, we will argue our way through several plausible proposals found in the literature. Upon discovering that none of these proposals seem entirely suited, we will reconsider our position and make several helpful observations into the nature of conditional sentences. And finally, in light of our observations, we shall propose and argue for plausible grounds for the indicative/subjunctive distinction.distinction. The fourth chapter offers semantics for modal and amodal natural language conditionals based on the distinction proposed in the previous chapter. First, the nature of modal and amodal suppositions will be explored. Armed with an analysis of modal and amodal suppositions, the corresponding conditionals will be examined further. Consequently, the syntax of conditionals in English will be uncovered for the purpose of providing input for our semantics. And finally, compositional semantics in generative grammar will be offered for modal and amodal conditionals. The fifth and final chapter defends Modus Ponens from alleged counterexamples. In particular, the chapter offers a solution to McGee’s infamous counterexamples. First, several solutions offered to the counterexamples hitherto are all argued to be inadequate. After a couple of observations on the counterexamples’ nature, a solution is offered and demonstrated. the solution suggests that the semantics of embedded natural language conditionals is more sophisticated than their surface syntax indicates. The heart of the solution is a translation function from the surface form of natural language conditionals to their logical form. Finally, the thesis ends with a conclusion that briefly summarises the main conclusions drawn in its preceding chapters.

Cette étude s’applique à démontrer comment la relation documentaire peut être mise à l’épreuve du pardon dans deux films mettant en scène des bourreaux. Comment est-il possible de concevoir un dispositif cinématographique éthique avec la participation d’anciens criminels ? C’est la question que se sont posée les cinéastes Avi Mograbi et Rithy Panh. L’objectif de cette recherche sera de relever comment le pardon intervient explicitement, mais aussi implicitement, dans la forme documentaire. Il s’agira de comprendre comment ces films, "Z32" et "S21 la machine de mort khmère rouge", s’élaborent socialement, politiquement et esthétiquement du tournage à la réception, afin de cerner le potentiel symbolique et performatif du pardon dans la reconstruction du lien avec autrui. / In this study we strive to show how the notion of relationship, conjured up by the documentary, is challenged by the act of forgiving in two films depicting executioners. Is it possible to conceive of a filmic project that would be at the same time ethical and include the participation of former criminals? Such is the question raised by the filmmakers Avi Mograbi and Rithy Panh. The purpose of our research will be to highlight instances where forgiveness unfolds, both explicitly and implicitly, in the documentary form. We will thus try to understand how the films "Z32" and "S21 la machine de mort khmère rouge" find a social, political and aesthetic existence, from shooting to reception. In this way the symbolic and performative potential of the act of forgiving will be revealed in its relation to the reconstruction of the bond with the other.
