Person to Person in England

While still in the midst of their study abroad experiences, students at Linfield College write reflective essays. Their essays address issues of cultural similarity and difference, compare lifestyles, mores, norms, and habits between their host countries and home, and examine changes in perceptions about their host countries and the United States. In this essay, Maria Raquel Escalera Gonzalez describes her observations during her study abroad program at the University of Nottingham in England

Usar la filosofía de Wittgenstein para eliminar conceptos erróneos en la práctica de la danza. Un enfoque cuádruple

A fourfold use of Wittgenstein’s later philosophy in order to tackle fundamental conceptual misconceptions in the domain of dance practice is proposed: the extension to dance of the insights of his remarks on other arts, the application to dance instructions of his method of examination of the use of language, the extension to dance of the insights of his remarks on aesthetics, and the use of some of the fundamental concepts of his later philosophy, such as “aspect-seeing”, or “form of life”. In the first section, Wittgenstein’s paragraphs on Shakespeare are used in order to clarify the nature of representation, his remarks on architecture are used to shed light on the gestural character of a dance movement and to differentiate dance movement from mere bodily movement, and his remarks on music are used in order to elucidate the relation ship between a movement and its so called meaning. In the second section, an analysis looks at how language is used in the dance studio to tackle the problem of affectation in dance practice, and to propose measures to overcome this tendency, such as awareness of the use of the mirror in the studio. In the third section, Wittgenstein’s understanding of aesthetic satisfaction as something that clicks is understood as a tool to fight dualistic tendencies in dance practice. The fourth section discusses how insight into Wittgenstein’s concepts of “aspect-seeing” and “form of life” can contribute to superseding affectation. In dance, aspect seeing involves directing one’s gaze back to the movement in question. Instead of blaming the incorrect execution of a movement on a lack of dramatic skill on the part of the dancer, an approach that reinforces the idea of dance performance as a dualistic process, it can be attributed to aspect blindness, allowing for the redirection of the dancer’s attention to the movement. In this regard, it is proposed that dancers be helped to appreciate that a movement is charged with the atmosphere of a whole form of life. By understanding this relationship, it should become clear for dancers that expressivity is something that depends neither on their mental state nor on their ability to transfer the latter to the movement in question.Propongo un uso cuádruple de la filosofía madura de Wittgenstein con vistas a abordar confusiones conceptuales fundamentales en el ámbito de la práctica de la danza: extender a la danza aquellas de sus observaciones perspicaces sobre otras artes que sean relevantes, aplicar a las instrucciones de danza su análisis del uso del lenguaje, extender a la danza sus observaciones sobre la estética y usar en el contexto de la danza algunos de los conceptos fundamentales de su filosofía madura, tales como el de «ver aspectos» o el de «forma de vida». En la primera sección, se usan los parágrafos sobre Shakespeare de Wittgenstein para clarificar la naturaleza de la representación, sus observaciones sobre arquitectura para arrojar luz sobre el carácter gestual del movimiento de danza y para diferenciar un movimiento de danza de un simple movimiento corporal. Asimismo, sus observaciones sobre música se usan con el fin de dilucidar la relación entre un movimiento y su presunto significado. En la segunda sección, analizo cómo se usa el lenguaje en el estudio de danza con vistas a afrontar el problema de la afectación en la práctica de la danza y propongo una serie de medidas con el propósito de superar esta tendencia, como, por ejemplo, tomar conciencia del uso del espejo en el estudio de danza. En la tercera sección, la comprensión de Wittgenstein de la satisfacción estética como algo que hace click se propone como herramienta para encarar las tendencias dualistas en la práctica de la danza. La cuarta sección enfoca cómo la familiaridad con los conceptos de Wittgenstein de «ver aspectos» y «forma de vida» puede contribuir a superar la afectación. En la danza, ver aspectos supone reencauzar la mirada, enfocando de nuevo el movimiento en cuestión. En lugar de echar la culpa de una ejecución incorrecta de un movimiento a una falta de talento dramático por parte del bailarín, idea que refuerza la imagen de la representación de danza como un proceso dualista, se podría atribuir a la ceguera para los aspectos, y así reorientar la atención del bailarín al movimiento. De igual modo, se propone que los bailarines deberían ser llevados a apreciar que un movimiento ha de participar de la atmósfera de toda una forma de vida. Tras comprender esta relación, para el bailarín debería resultar evidente que la expresividad no es algo que dependa de su estado mental, ni de su habilidad para transferir ese estado mental al movimiento en cuestión

Unveiling the Effect of Magnetic Noise in the Coherence of Single-Molecule Quantum Processors

Quantum bits (qubits) constitute the most elementary building-blocks of any quantum technology, where information is stored and processed in the form of quantum superpositions between discrete energy levels. In particular, the fabrication of quantum processors is a key long-term goal that will allow us conducting specific tasks much more efficiently than the most powerful classical computers can do. Motivated by recent experiments in which three addressable spin qubits are defined on a potential single-molecule quantum processor, namely the [Gd(H2O)P5W30O110]12− polyoxometalate, we investigate the decohering effect of magnetic noise on the encoded quantum information. Our state-of-the-art model, which provides more accurate results than previous estimates, show a noticeable contribution of magnetic noise in limiting the survival timescale of the qubits. Yet, our results suggest that it might not be the only dephasing mechanism at play but other mechanisms, such as lattice vibrations and physical movement of magnetic nuclei, must be considered to understand the whole decoherence process

Bridging the Gap: A Pentadic Analysis of Theresa May’s Conservative Conference Speech “Britain after Brexit: A Vision of a Global Britain”

This qualitative study of British Prime Minister Theresa May’s Conservative conference speech “Britain after Brexit: A Vision of a Global Britain” delivered in the fall of 2016 uses pentadic criticism as the basis for its analysis. This contemporary study identifies women as an underrepresented minority in the realm of politics around the world and media as a powerful channel for their portrayal. As the role of women in political leadership is more prevalent in times of crisis around the world, it is exceedingly important to understand the role that the media can play in their portrayal for both foreign and domestic audiences alike. This study reaffirms that more women in leadership within politics is needed for equitable gender representation in politics. May’s speech and her portrayal within the media for both foreign and domestic audiences show that it is possible for women to bridge the gap of gender and politics

Conditions Pertinent for Overcoming Gender Inequality in Political Leadership: A Comparative Analysis of Angela Merkel and Ellen Johnson Sirleaf

This qualitative study of Liberian President Ellen Johnson Sirleaf and Chancellor Angela Merkel of Germany implements a most different systems design (MDSD) as the basis for its comparative analysis. A cross-examination of Johnson Sirleaf’s and Merkel’s personal backgrounds, their leadership styles in their political careers before they became the heads of their governments, and their level of political participation in democracy or liberalization movements prior to their rise to power is conducted in this study. Key strands of feminist approaches in IR, such as liberal feminism, difference feminism, and postmodern feminism add to this study’s discourse on Johnson Sirleaf’s and Merkel’s rise to political power. The basis for this study is that women comprise an underrepresented minority in the field of politics worldwide. As women in political leadership is more prevalent in times of crisis around the world, it is exceedingly important to understand the conditions under which women political leaders may attain their country’s highest political office. More so, this study identifies some key similar conditions from which Angela Merkel and Ellen Johnson Sirleaf overcame gendered obstacles in politics to reach their country’s highest political offices

Folded Recurrent Neural Networks for Future Video Prediction

Future video prediction is an ill-posed Computer Vision problem that recently received much attention. Its main challenges are the high variability in video content, the propagation of errors through time, and the non-specificity of the future frames: given a sequence of past frames there is a continuous distribution of possible futures. This work introduces bijective Gated Recurrent Units, a double mapping between the input and output of a GRU layer. This allows for recurrent auto-encoders with state sharing between encoder and decoder, stratifying the sequence representation and helping to prevent capacity problems. We show how with this topology only the encoder or decoder needs to be applied for input encoding and prediction, respectively. This reduces the computational cost and avoids re-encoding the predictions when generating a sequence of frames, mitigating the propagation of errors. Furthermore, it is possible to remove layers from an already trained model, giving an insight to the role performed by each layer and making the model more explainable. We evaluate our approach on three video datasets, outperforming state of the art prediction results on MMNIST and UCF101, and obtaining competitive results on KTH with 2 and 3 times less memory usage and computational cost than the best scored approach.Comment: Submitted to European Conference on Computer Visio

LSTA: Long Short-Term Attention for Egocentric Action Recognition

Egocentric activity recognition is one of the most challenging tasks in video analysis. It requires a fine-grained discrimination of small objects and their manipulation. While some methods base on strong supervision and attention mechanisms, they are either annotation consuming or do not take spatio-temporal patterns into account. In this paper we propose LSTA as a mechanism to focus on features from spatial relevant parts while attention is being tracked smoothly across the video sequence. We demonstrate the effectiveness of LSTA on egocentric activity recognition with an end-to-end trainable two-stream architecture, achieving state of the art performance on four standard benchmarks.Comment: Accepted to CVPR 201
