Swinging Gait Patterns and Preferred Rung Spacing During Free Choice Horizontal Ladder Traverses

Roth, Charles H. (Charles Hillary) 08 1900 (has links)
Fifty-one subjects each performed two trials which consisted of traversing a horizontal ladder. Film records were made of each trial using a high-speed camera. Absolute and relative temporal and kinematic parameters were obtained from the film records. The conclusions were that there was no age related interaction or differences in preferred rung spacing or contact/airborne times. A Chi-Square analysis did show a preference for a specific gait pattern for the six year old age group.

Kleist and Hoffmann in dialogue with enlightenment

Hall, William January 2018 (has links)
This thesis considers how Kleist and Hoffmann’s fiction might be considered as responding to the perceived shortcomings of enlightenment. The two writers, despite the barriers of literary categorisations, have a striking affinity in their sense that notions of truth and knowledge are intertwined with social and political agendas, rather than forming part of some natural teleology. The thesis breaks new ground in viewing the texts within a more expansive discourse context as literary interventions within a broad, cross-society engagement with enlightenment, in its various streams and factions. The texts studied, I argue, represent thought experiments, not merely reflecting and re-articulating the influences of literary peers and historically significant events, but instead testing the real-world application of key enlightenment ideas. The driving force for this thesis is the need to locate their work more rigorously in relation to enlightenment thought of their time than has previously been attempted. This is not so much a question of retrieving past influences, as one of viewing their work as being in dialogue with contemporary thought. Moving away from attempts using Kleist’s letters to theorise the relation between Kleist and Kant, this investigation instead turns to aspects of Kant’s philosophy to illuminate the texts. Hoffmann’s relationship to enlightenment, too, is explored beyond the prism of Romanticism. Taking a more comparative approach than previous work on the two writers, I identify not only thematic commonalities, but also a parallel aesthetic, in which multiple narratives coexist and where ‘truth’ is manufactured by the dominance of one particular narrative. The notion of 'MÃ1⁄4ndigkeit', central to Kant’s famous definition of 'Aufklärung' offers a useful guiding concept for the investigation and captures the emancipatory promise of self-realisation and the positive trajectory of human progress at the heart of the miscellany of moral and political theories and philosophies collectively known as ‘enlightenment’. The latter refers not to the historical period, but rather to a process of intellectual emancipation and an assemblage of ideals and values. As an intellectual movement, enlightenment was not, as is often assumed, monolithic, but encompasses conflicting notions of reason, freedom, and how its goals were to be achieved. Not only are the certainty and consequences of this intellectual emancipation evaluated in the texts, but I have also identified a radical questioning of the paradigms of thought which condition our understanding of narratives. Both Kleist and Hoffmann’s texts are narratively complex, often with shifts in focalisation, jumps in time, occasionally, figures whose identity changes leave the reader uncertain whether they are dealing with more than one character, and depictions of events which resist clarification through conventional understandings of time, space and causality. This project seeks to reconcile these ‘blind spots’ with a broader critique of enlightenment, in which absolute knowledge is shown to be illusory and truth simply reflective of constellations of power. The spatiotemporal and causal frameworks foundational to rational understanding and used to make sense of the world are revealed to be inadequate.

Online product decision support using sentiment analysis and fuzzy cloud-based multi-criteria model through multiple e-commerce platforms

Yang, Z., Li, Q., Vincent, Charles, Xu, B., Gupta, S. 22 April 2023 (has links)
Yes / The competitive landscape of multiple e-commerce platforms and the vast amount of product reviews associated with these platforms have supported both consumers’ online shopping decision making and also served as a reference for product attribute performance improvement. This paper proposes a sentiment-driven fuzzy cloud multi-criteria model for online product ranking and performance to provide purchase recommendations. In this novel model, Bi-directional Long Short-Term Memory Network-Conditional Random Fields (BiLSTM-CRF), sentiment analysis, and K-means clustering are first integrated to mine product attributes and compute sentiment values based on reviews from various platforms. Next, considering the confidence of the sentiment value, the cloud model is combined with q-rung orthopair fuzzy sets to define the new concept of the q-rung orthopair fuzzy cloud (q-ROFC) and the interaction operational laws between q-ROFCs are given. The sentiment values of each product attribute from different platforms are cross-combined and transformed into a type of q- ROFC, while multiple interactive information matrices are established. To investigate the correlation among homogeneous attributes, the q-ROFC interaction weighted partitioned Maclaurin Symmetric mean operator is proposed. Finally, we provide real-world examples of online mobile phone ranking and attribute performance evaluation. The results show that our proposed method offers significant advantages in dealing with customer purchase decisions for online products and problems with performance direction identification. Managerial implications are discussed.

Edmund Burke's German readers at the end of Enlightenment, 1790-1815

Green, Jonathan January 2018 (has links)
Amidst the upheaval of the French Revolution, the British parliamentarian and political theorist Edmund Burke received a vibrant reception in German-speaking Europe. Anxious to uncover the ideological roots of the anarchy that enveloped France – and worried that their own society might be vulnerable to a similar fate – a series of important German thinkers began studying his Reflections on the Revolution in France (1790). This dissertation brings into focus the diverse interpretations of Burke that were assembled in this turbulent era, and explains them vis-à-vis contemporary debates among German idealists (Kant and his heirs) about the philosophical nature of freedom. This dissertation centers on Burke’s three most perceptive and influential students: the civil servant and philosopher August Wilhelm Rehberg; the journalist, translator, and diplomat Friedrich Gentz; and the political economist and cultural critic Adam Müller. For many decades, both German- and English-speaking intellectual historians have shoehorned these thinkers into a rigid ideological box labeled ‘conservatism’. Inspired by Burke, they are said to have turned away from the ideals of Enlightenment, theorizing an illiberal form of politics that was traditionalistic, authoritarian, and reactionary. A careful, contextualized reconstruction of their engagements with Burke, however, renders this thesis untenable. Far from triggering a monolithic backlash against Enlightenment, Burke in fact inspired a series of divergent, and often incompatible, analyses of the Revolution’s origins, grounded in different readings of his Reflections. Rehberg, for instance, saw Burke as a principled skeptic: he admired the Reflections as an incisive critique of the revolutionaries’ philosophical dogmatism. Gentz, an erstwhile student of Kant, disagreed completely, arguing that Burke’s politics were entirely compatible with Kantian metaphysics. In his view, the Reflections’ central insight was that it takes political prudence to realize the rights of man in practice. Müller, finally, read the Reflections as a lament for the fall of Christendom, and as a diagnosis of the social alienation and moral confusion that had followed its demise. In other words, whereas Rehberg was a Humean skeptic and Gentz was a Kantian liberal, Müller was a Trinitarian Christian. Each of these men, moreover, claimed Burke as an ally. What this means is that Rehberg, Gentz, and Müller cannot have jointly invented a single thing called ‘conservatism’, and Burke cannot have inspired it. This becomes clear only after we recognize that at the turn of the nineteenth century, neither the meaning of Enlightenment nor the crux of Burke’s Reflections was clear: these were not fixed variables, but points of contemporary debate. By recapturing the diversity of Burke’s German reception, this thesis invites scholars to consider the ways that his students shepherded their differing visions of Enlightenment through the fires of the Revolution, down into the nineteenth century.
