    Coloniality and the Courtroom: Understanding Pre-trial Judicial Decision Making in Brazil

    This thesis focuses on judicial decision making during custody hearings in Rio de Janeiro, Brazil. The impetus for the study is that while national and international protocols mandate the use of pre-trial detention only as a last resort, judges continue to detain people pre-trial in large numbers. Custody hearings were introduced in 2015, but the initiative has not produced the reduction in pre-trial detention that was hoped. This study aims to understand what informs judicial decision making at this stage. The research is approached through a decolonial lens to foreground legacies of colonialism, overlooked in mainstream criminological scholarship. This is an interview-based study, where key court actors (judges, prosecutors, and public defenders) and subject matter specialists were asked about influences on judicial decision making. Interview data is complemented by non-participatory observation of custody hearings. The research responds directly to Aliverti et al.'s (2021) call to ‘decolonize the criminal question’ by exposing and explaining how colonialism informs criminal justice practices. Answering the call in relation to judicial decision making, findings provide evidence that colonial-era assumptions, dynamics, and hierarchies were evident in the practice of custody hearings and continue to inform judges’ decisions, thus demonstrating the coloniality of justice. This study is significant for the new empirical data presented and theoretical innovation is also offered via the introduction of the ‘anticitizen’. The concept builds on Souza’s (2007) ‘subcitizen’ to account for the active pursuit of dangerous Others by judges casting themselves as crime fighters in a modern moral crusade. The findings point to the limited utility of human rights discourse – the normative approach to influencing judicial decision making around pre-trial detention – as a plurality of conceptualisations compete for dominance. This study has important implications for all actors aiming to reduce pre-trial detention in Brazil because unless underpinning colonial logics are addressed, every innovation risks becoming the next lei para inglĂȘs ver (law [just] for the English to see)

    Identification of Hindbrain Neural Substrates for Motor Initiation in the hatchling Xenopus laevis Tadpole

    Animal survival profoundly depends on the ability to detect stimuli in the environment, process them and respond accordingly. In this respect, motor responses to a sensory stimulation evolved into a variety of coordinated movements, which involve the control of brain centres over spinal locomotor circuits. The hatchling Xenopus tadpole, even in its embryonic stage, is able to detect external sensory information and to swim away if the stimulus is considered noxious. To do so, the tadpole relies on well-known ascending sensory pathway, which carries the sensory information to the brain. When the stimulus is strong enough, descending interneurons are activated, leading to the excitation of spinal CPG neurons, which causes the undulatory movement of swimming. However, the activation of descending interneurons that marks the initiation of motor response appears after a long delay from the sensory stimulation. Furthermore, the long-latency response is variable in time, as observed in the slow-summating excitation measured in descending interneurons. These two features, i.e. long-latency and variability, cannot be explained by the firing time and pattern of the ascending sensory pathway of the Xenopus tadpole. Therefore, a novel neuronal population has been proposed to lie in the hindbrain of the tadpole, and being able to 'hold' the sensory information, thus accounting for the long and variable delay of swim initiation. In this work, the role of the hindbrain in the maintenance of the long and variable response to trunk skin stimulation is investigated in the Xenopustadpole at developmental stage 37/38. A multifaceted approach has been used to unravel the neuronal mechanisms underlying the delayed motor response, including behavioural experiments, electrophysiology analysis of fictive swimming, hindbrain extracellular recordings and imaging experiments. Two novel neuronal populations have been identified in the tadpole's hindbrain, which exhibit activation patterns compatible with the role of delaying the excitation of the spinal locomotor circuit. Future work on cellular properties and synaptic connections of these newly discovered populations might shed light on the mechanism of descending control active at embryonic stage. Identifying supraspinal neuronal populations in an embryonic organism could aid in understanding mechanisms of descending motor control in more complex vertebrates

    The clinical data for the studies was collected at The PROMIS Recovery Centre, a Minnesota Model treatmentc entre for addictions,w hich encouragesth e membership and use of the 12 step Anonymous Fellowships, and is abstinence based. The area of addiction is contextualised in a review chapter which focuses on research relating to the phenomenon of cross addiction. A study examining the concept of "addictive orientations" in male and female addicts is described, which develops a study conductedb y StephensonM, aggi, Lefever, & Morojele (1995). This presents study found a four factor solution which appeared to be subdivisions of the previously found Hedonism and Nurturance factors. Self orientated nurturance (both food dimensions, shopping and caffeine), Other orientated nurturance (both compulsive helping dimensions and work), Sensation seeking hedonism (Drugs, prescription drugs, nicotine and marginally alcohol), and Power related hedonism (Both relationship dimensions, sex and gambling. This concept of "addictive orientations" is further explored in a non-clinical population, where again a four factor solution was found, very similar to that in the clinical population. This was thought to indicate that in terms of addictive orientation a pattern already exists in this non-clinical population and that consideration should be given to why this is the case. These orientations are examined in terms of gender differences. It is suggested that the differences between genders reflect power-related role relationships between the sexes. In order to further elaborate the significance and meaning behind these orientations, the next two chapters look at the contribution of personality variables and how addictive orientations relate to psychiatric symptomatology. Personality variables were differentially, and to a considerable extent predictably involved with the four factors for both males and females.Conscientiousness as positively associated with "Other orientated Nurturance" and negatively associated with "Sensation seeking hedonism" (particularly for men). Neuroticism had a particularly strong association with the "Self orientated Nurturance" factor in the female population. More than twice the symptomatology variance was explained by the factor scores for females than it was for males. The most important factorial predictors for psychiatric symptomatology were the "Power related hedonism" factor for males, and "Self oriented nurturance" for females. The results are discussed from theoretical and treatment perspectives

    Strung pieces: on the aesthetics of television fiction series

    Get PDF
    As layered and long works, television fiction series have aesthetic properties that are built over time, bit by bit. This thesis develops a group of concepts that enable the study of these properties, It argues that a series is made of strung pieces, a system of related elements. The text begins by considering this sequential form within the fields of film and television. This opening chapter defines the object and methodology of research, arguing for a non-essentialist distinction between cinema and television and against the adequacy of textual and contextual analyses as approaches to the aesthetics of these shows. It proposes instead that these programmes should be described as televisual works that can be scrutinised through aesthetic analysis. The next chapters propose a sequence of interrelated concepts. The second chapter contends that series are composed of building blocks that can be either units into which series are divided or motifs that unify series and are dispersed across their pans. These blocks are patterned according to four kinds of relations or principles of composition. Repetition and variation are treated in tandem in the third chapter because of their close connection, given that variation emerges from established repetition. Exception and progression are also discussed together in the fourth chapter since they both require a long view of these serial works. The former, in order to be recognised as a deviation from the patterns of repetition and variation. The latter, In order to be understood in Its many dimensions as the series advances. Each of these concepts is further detailed with additional distinctions between types of units, motifs, repetitions, variations, and exceptions, using illustrative examples from numerous shows. In contrast, the section on progression uses a single series as case study, CarnivĂ le (2003-05), because this is the overarching principle that encompasses all the others. The conclusion considers the findings of the research and suggests avenues for their application

    Pontus in Antiquity: aspects of identity

    Get PDF
    The purpose of this thesis is the presentation of the interaction between the successive inhabitants of Pontus in antiquity, indigenous Anatolians, Greeks, Persians and Romans. Limited archaeological evidence cannot determine the precise extent of interaction, although the available information substantiates the notion of a slow, but steady amalgamation. Initially, the intermingling was based on mutual trading links. Although the Hellenic cultural element tended to surface, Eastern factors remained visible. The Mithridatic dynasty was established around the vicinity of Pontus, creating the 'Kingdom of Pontus' which reached its height under Mithridates VI. His administrative and military policy appears to have placed the foundations for the later, Roman corresponding structures. His policies-propaganda reflected the GraecoEastern image of a king, which appealed to the Greek and Persian-Eastern inhabitants of his kingdom, Asia Minor and, to a lesser extent, mainland Greece. This GraecoEastern image might have nourished the concept of a shared history among the inhabitants of Pontus. Their interactions appear to have given rise to an unnamed, local culture, which was enriched with the relevant Roman practices. Around the third century A.D., the Roman administrative patterns might have established an externally defined appellation. During Roman times, Christianity started to be established in Pontus. Although it was not yet a socio-political factor, its non-racial nature prevailed in later centuries. The influence of the Roman-Christian elements can still be observed in the modern Ponti an identity. In antiquity, (lack of) evidence indicates that no group defined themselves as 'Pontics' or 'Pontians' and an internally defined Pontic identity is unlikely to have existed. However, people associated themselves with the geographical area of Pont us, cultural and religious concepts were frequently amalgamated, while the notion of a common descent and a shared history might have been unconsciously fostered. These factors can assist in the understanding of the 'Pontians' today

    A Cornish palimpsest : Peter Lanyon and the construction of a new landscape, 1938-1964

    The thesis examines the emergence of Peter Lanyon as one of the few truly innovative British landscape painters this century. In the Introduction I discuss the problematic nature of landscape art and consider the significance of Lanyon's discovery that direct description and linear perspective can be replaced with allusive representational elements by fusing the emotional and imaginative life of the artist with the physical activity of painting. Chapter One concentrates on the period 1936-8 when Lanyon was taught by Borlase Smart, a key figure in the St Ives art colony between the wars. Chapter Two examines the influence of Adrian Stokes and the links between Lanyon's painting and the theories developed in books such as Colour and Form and The Quattro Cento. Chapter Three analyses the period 1940-45 when Lanyon was directly influenced by the constructivism of Nicholson, Hepworth and Gabo. I look closely at their approaches to abstraction and assess Lanyon's relative position to them. The importance of Neo-Romanticism and the status of St Ives as a perceived avant-garde community is also addressed. In Chapter Four I discuss how Lanyon resolved to achieve a new orientation in his art on his return from wartime service with the RAF by synthesising constructivism, and traditional landscape. The Generation and Surfacing Series demonstrate his preoccupation with a sense of place, a fascination with the relationships between the human body and landscape and his struggle to find a technique and style that was entirely his own. His sense of existential insideness is discussed in Chapter Five through an examination of the work derived from Portreath, St. Just and Porthleven - key places in Lanyon's psychological attachment to the landscape of West Penwith. In Chapter Six I examine Lanyon's attachment to myths and archetypal forms, tracing the influence of Bergson's vitalist philosophy as well as his use of Celtic and classical motifs. Chapter Seven is a discussion of the malaise evident in Lanyon's work by 1955 and the impact of American Abstract Expressionism at the Tate Gallery a year later. In the summer of 1959 Lanyon joined the Cornish Gliding Club and Chapter Eight looks at how this necessitated a dynamic, expanded conception of the landscape and a re-thinking of relations within the picture field. The ability to dissolve boundaries encouraged him to break down distinctions between painting and construction so that abstract sculptural elements were now assembled into independent works of art. Finally, Chapter Nine assesses Lanyon's overall position in relation to his early influences and to St Ives art as a whole, his response to new directions in art coming out of London and NewYork in the early 1960s and the importance of travel as a stimulus for further realignment in his artistic and topographical horizons. His pictorial inventiveness and vitality remained unabated at the time of his death and would undoubtedly have continued to be enriched by travel abroad and contact with new movements in modem art on both sides of the Atlanti
