Reclaiming Indigenous Narratives through Critical Discourses and the Autonomy of the Trickster

How do prevailing narratives about Native Americans, particularly in the medium of film, conspire to promote the perspective of the dominant culture? What makes the appropriation of Indigenous images so metaphorically popular? In the past hundred years, little has changed in the forms of representation favored by Hollywood. The introductory chapter elucidates the problem and outlines the scope of this study. As each subsequent chapter makes clear, the problem is as relevant today as it has been throughout the entire course of filmic history. Chapter Two analyzes representational trends and defines each decade according to its favorite stereotype. The binary of the bloodthirsty savage is just as prevalent as it was during the 1920s and 30s. The same holds true for the drunken scapegoat and the exotic maiden, which made their cinematic debuts in the 1940s and 50s. But Hollywood has added new types as well. The visionary peacemaker and environmental activist have also made an appearance within the last forty years. What matters most is not the realism of these images, but rather the purposes to which they can be put toward validating whatever concerns the majority filmmakers wish to promote. Whether naïvely or not, such representations continue to evacuate Indigenous agency to the advantage of the majority. A brief historical overview confirms this legacy. Various disciplines have sought to interrogate this problem. Chapter three investigates the field of postcolonial studies, which makes inquiry into the various ways these narratives are produced, marketed, and consumed. It also raises the key questions of for whom, and by whom, these narratives are constructed. Additional consideration is given to their value as commodities in the mass marketplace. Typically the products of a boutique-multiculturalism, their storylines are apt to promote the prevailing point of view. Critical theory provides a foundational framework for chapter four. What is the blockbuster formula and how do the instruments of capital promote it? Concepts such as culture industry and repressive tolerance examine both the function and form of the master narrative, as well as its use to control the avenues of dissent. Moreover, the public sphere and its diminishment highlight the challenges inherent in the widespread promotion of an alternative set of narratives. Nonetheless, challenges to prevailing narratives do exist, particularly in the form of Trickster narratives. Often subject to persistent misrecognition, the Trickster demonstrates a potent form of agency that undeniably dismantles the hegemony of Western cinema. The final chapter examines some of the Trickster's more subtle and obscure productions. Usually subjugated to the realm of the mystical, rather than the mythical, these misinterpreted forms have the power to speak in circles around a majority audience. Intended for an Other audience, they are coded in a language that delivers a type of direction through indirection, promoting a poignant agency all their own.

View-Dependent Extraction of Contours with Distance Transforms for Adaptive Polygonal for adaptive polygonal Mesh-Simplification

During decades Distance Transforms have proven to be useful for many image processing applications, and more recently, they have started to be used in computer graphics environments. The goal of this paper is to propose a new technique based on Distance Transforms for detecting mesh elements which are close to the objects' external contour (from a given point of view), and using this information for weighting the approximation error which will be tolerated during the mesh simplification process. The obtained results are evaluated in two ways: visually and using an objective metric that measures the geometrical difference between two polygonal meshes.

Head Tracking Based Avatar Control for Virtual Environment Teamwork Training

Virtual environments (VE) are gaining in popularity and are increasingly used for teamwork training purposes, e.g., for medical teams. One shortcoming of modern VEs is that nonverbal communication channels, essential for teamwork, are not supported well. We address this issue by using an inexpensive webcam to track the user's head. This tracking information is used to control the head movement of the user's avatar, thereby conveying head gestures and adding a nonverbal communication channel. We conducted a user study investigating the influence of head tracking based avatar control on the perceived realism of the VE and on the performance of a surgical teamwork training scenario. Our results show that head tracking positively influences the perceived realism of the VE and the communication, but has no major influence on the training outcome.

Brain electric correlates of strong belief in paranormal phenomena: intracerebral EEG source and regional Omega complexity analyses

The neurocognitive processes underlying the formation and maintenance of paranormal beliefs are important for understanding schizotypal ideation. Behavioral studies indicated that both schizotypal and paranormal ideation are based on an overreliance on the right hemisphere, whose coarse rather than focussed semantic processing may favor the emergence of 'loose' and 'uncommon' associations. To elucidate the electrophysiological basis of these behavioral observations, 35-channel resting EEG was recorded in pre-screened female strong believers and disbelievers during resting baseline. EEG data were subjected to FFT-Dipole-Approximation analysis, a reference-free frequency-domain dipole source modeling, and Regional (hemispheric) Omega Complexity analysis, a linear approach estimating the complexity of the trajectories of momentary EEG map series in state space. Compared to disbelievers, believers showed: more right-located sources of the beta2 band (18.5-21 Hz, excitatory activity); reduced interhemispheric differences in Omega complexity values; higher scores on the Magical Ideation scale; more general negative affect; and more hypnagogic-like reveries after a 4-min eyes-closed resting period. Thus, subjects differing in their declared paranormal belief displayed different active, cerebral neural populations during resting, task-free conditions. As hypothesized, believers showed relatively higher right hemispheric activation and reduced hemispheric asymmetry of functional complexity. These markers may constitute the neurophysiological basis for paranormal and schizotypal ideation.

Das Paradigma des kritischen Realismus

Der Kritische Realismus („Critical Realism“) ist seit Ian G. Barbours grundlegenden Issues in Science and Religion (1966) erkenntnistheoretisches Paradigma zentraler Ansätze im angelsächsischen Gespräch zwischen Theologie und Naturwissenschaften geworden; neben Barbour selbst sind hier insbesondere Arthur Peacocke und John Polkinghorne zu nennen.

Self-reported attenuated psychotic-like experiences in help-seeking adolescents and their association with age, functioning and psychopathology

OBJECTIVE Self-rated attenuated psychotic-like experiences (APLEs) are increasingly used to screen for ultra-high-risk (UHR) across all ages. However, self-rated psychotic-like experiences (PLEs), in particular perception-related ones, were more frequent in children and adolescents, in which they possessed less clinical significance. We therefore explored the prevalence of different factors of APLEs in help-seeking adolescents, and their relationship with age, functioning and psychopathology METHOD As a part of the "Liberiamo il Futuro" project, help-seeking adolescents (N=171; 11-18years, 53% male) were screened with the 92-item Prodromal Questionnaire (PQ-92). A factor analysis was performed on the PQ-92 positive items (i.e., APLEs) to identify different APLE-factors. These were assessed for their association with age, functioning and psychopathology using regression analyses. RESULTS APLEs were very common in help-seeking adolescents, and formed four factors: "Conceptual Disorganization and Suspiciousness", "Perceptual Abnormalities", "Bizarre Experiences", and "Magical Ideation". Associations with age and functioning but not psychopathology were found for "Perceptual Abnormalities" that was significantly more severe in 11-12-year-olds, while "Conceptual Disorganization and Suspiciousness" was significantly related to psychopathology. CONCLUSION In line with findings on PLEs, prevalence and clinical significance of APLEs, especially perception-related ones, might depend on age and thus neurodevelopmental stage, and may fall within the normal spectrum of experience during childhood. This should be considered when screening for UHR status in younger age groups

Loose but normal: a semantic association study.

An abnormal facilitation of the spreading activation within semantic networks is thought to under-lie schizophrenics' remote associations and referential ideas. In normal subjects, elevated magical ideation (MI) has also been associated with a style of thinking similar to that of schizotypal subjects. We thus wondered whether normal subjects with a higher MI score would judge "loose associations" as being more closely related than do subjects with a lower MI score. In two experiments, we investigated whether judgments of the semantic distance between stimulus words varied as a function of MI. In the first experiment, random word pairs of two word classes, animals and fruits, were presented. Subjects had to judge the semantic distance between word pairs. In the second experiment, sets of three words were presented, consisting of a pair of indirectly related, or unrelated nouns plus a third noun. Subjects had to judge the semantic distance of the third noun to the word pair The results of both experiments showed that higher MI subjects considered unrelated words as more closely associated than did lower MI subjects. We conjecture that for normal subjects high on MI "loose associations" may not be loose after all. We also note that the tendency to link uncommon, nonobvious, percepts may not only be the basis of paranormal and paranoid ideas of reference, but also a prerequisite of creative thinking.

Swiss Adolescents' Career Aspirations: Influence of Context, Age, and Career Adaptability

This study investigated the content, realism, stability, and coherence of the career aspirations of 262 students in seventh grade in Switzerland (ages 13-15 years). The content analysis revealed that 82% of the participants named at least one realistic career aspiration, and aspirations showed clear resemblance to existing opportunities in the environment. Quantitative analyses confirmed the hypotheses that realism and stability of aspirations over a 10-month period could better be predicted by individual degree of career adaptability as measured by planfulness and exploration than by chronological age when grade level was controlled for. Coherence of aspirations was not related to age or adaptability. Students attending basic scholastic requirements school tracks reported more adaptability but not more realistic, stable, or coherent aspirations compared to students in advanced requirements tracks.

Holland's secondary constructs of vocational interests and career choice readiness of secondary students

The study examined the relationship between the secondary constructs of Holland’s (1997) theory of vocational interests and career choice readiness [career maturity] attitudes with 358 Swiss secondary students. The hypothesis was tested that the secondary constructs consistency, coherence, differentiation, and congruence are measures for the degree of vocational interest development. Thus, they should belong to the content domain in career choice readiness and should show meaningful relations to career choice readiness attitudes. The hypothesis was confirmed for congruence, coherence, and differentiation. Interest profile consistency showed no relation to career choice readiness attitudes. Vocational identity emerged as a direct measure for career choice readiness attitudes. Realism of career aspirations was related to career choice readiness attitudes and coherence of career aspirations. Profile elevation was positively connected to more career planning and career exploration. Differences between gender, ethnicity, and school-types are presented. Implications for career counselling and assessment practice are discussed.

To research living beings one has to participate in life.' Viktor von Weizsäcker's legacy

Viktor von Weizsäcker has been a German medical doctor and philosopher, well known throughout Europe, but hardly received in the Anglo-American culture. He focusses on the crucial epistemological question how one can conduct research on living beings. The article’s title represents a key quote of his opus magnum “Der Gestaltkreis”, which works out a theory of the unity of perception and motion. According to Viktor von Weizsäcker, one cannot separate the two, meaning that we locate ourselves in a fundamental union with the living world, which has lasting influence on our capacity of perception. This idea does not seem too different from Ian Barbour’s idea about critical realism, exploring a “consciousness of ourselves as arising out of rapport, interconnection and participation in processes reaching beyond ourselves.” Both authors, Viktor von Weizsäcker and Ian Barbour, still have lasting influence on the dialog between religion and science, each in their respective cultures – a further reason to compare their core ideas, after presenting Viktor von Weizsäcker’s life and thought. Finally, the theological impact of von Weizsäcker’s thought will be assessed. Following his philosophy, it becomes clear that the miracle of creation is the condition of the possibility of any perception.

Quantum Nondemolition Measurement Enables Macroscopic Leggett-Garg Tests

We show how a test of macroscopic realism based on Leggett-Garg inequalities (LGIs) can be performed in a macroscopic system. Using a continuous-variable approach, we consider quantum nondemolition (QND) measurements applied to atomic ensembles undergoing magnetically driven coherent oscillation. We identify measurement schemes requiring only Gaussian states as inputs and giving a significant LGI violation with realistic experimental parameters and imperfections. The predicted violation is shown to be due to true quantum effects rather than to a classical invasivity of the measurement. Using QND measurements to tighten the “clumsiness loophole” forces the stubborn macrorealist to recreate quantum backaction in his or her account of measurement.

Dramas of Recognition: Philosophy as Literary History

Offers a critique of the concept of recognition (Honneth, Fraser), arguing that, from a literary-historical perspective, it connstitutes a step back behing modernism toward the agenda of Realism.

Crafting strategy : embodied metaphors in practice

The rationalist approach to strategizing emphasizes analytical and convergent thinking. Without denying the importance of this approach, this book argues that strategists must learn to complement it with a more creative approach to strategizing that emphasizes synthetic and divergent ways of thinking. The theoretical underpinnings of this approach include embodied realism, interpretivism, practice theory, theory of play, design thinking, as well as discursive approaches such as metaphorical analysis, narrative analysis, dialogical analysis and hermeneutics. The book includes in-depth discussions of these theories and shows how they can be put into practice by presenting detailed analyses of embodied metaphors built by groups of agents with step-by-step explanations of how this process can be implemented and facilitated. The link between theory and practice is further supported by the inclusion of several vignettes that describe how this approach has been successfully employed in a number of organizations, including BASF and UNICEF

Expanding Our Grasp: Causal Knowledge and the Problem of Unconceived Alternatives

I argue that scientific realism, insofar as it is only committed to those scientific posits of which we have causal knowledge, is immune to Kyle Stanford’s argument from unconceived alternatives. This causal strategy (previously introduced, but not worked out in detail, by Anjan Chakravartty) is shown not to repeat the shortcomings of previous realist responses to Stanford’s argument. Furthermore, I show that the notion of causal knowledge underlying it can be made sufficiently precise by means of conceptual tools recently introduced into the debate on scientific realism. Finally, I apply this strategy to the case of Jean Perrin’s experimental work on the atomic hypothesis, disputing Stanford’s claim that the problem of unconceived alternatives invalidates a realist interpretation of this historical episode.

A study to determine the association between medical decision-making and the performance of an institutional ethics committee

This study developed proxy measures to test the independent effects of medical specialty, institutional ethics committee (IEC) and the interaction between the two, upon a proxy for the dependent variable of the medical decision to withhold/withdraw care for the dying--the resuscitation index (R-index). Five clinical vignettes were constructed and validated to convey the realism and contextual factors implicit in the decision to withhold/withdraw care. A scale was developed to determine the range of contact by an IEC in terms of physician knowledge and use of IEC policy.^ This study was composed of a sample of 215 physicians in a teaching hospital in the Southwest where proxy measures were tested for two competing influences, medical specialty and IEC, which alternately oppose and support the decision to withhold/withdraw care for the dying. A sub-sample of surgeons supported the hypothesis that an IEC is influential in opposing the medical training imperative to prolong life.^ Those surgeons with a low IEC score were 326 percent more likely to continue care than were surgeons with a high IEC score when compared to all other specialties. IEC alone was also found to significantly predict the decision to withhold/withdraw care. Interaction of IEC with the specialty of surgery was found to be the best predictor for a decision to withhold/withdraw care for the dying. ^
