Drawing a baseline in aesthetic quality assessment

Aesthetic classification of images is an inherently subjective task. There does not exist a validated collection of images/photographs labeled as having good or bad quality from experts. Nowadays, the closest approximation to that is to use databases of photos where a group of users rate each image. Hence, there is not a unique good/bad label but a rating distribution given by users voting. Due to this peculiarity, it is not possible to state the problem of binary aesthetic supervised classification in such a direct mode as other Computer Vision tasks. Recent literature follows an approach where researchers utilize the average rates from the users for each image, and they establish an arbitrary threshold to determine their class or label. In this way, images above the threshold are considered of good quality, while images below the threshold are seen as bad quality. This paper analyzes current literature, and it reviews those attributes able to represent an image, differentiating into three families: specific, general and deep features. Among those which have been proved more competitive, we have selected a representative subset, being our main goal to establish a clear experimental framework. Finally, once features were selected, we have used them for the full AVA dataset. We have to remark that to perform validation we report not only accuracy values, which is not that informative in this case, but also, metrics able to evaluate classification power within imbalanced datasets. We have conducted a series of experiments so that distinct well-known classifiers are learned from data. Like that, this paper provides what we could consider valuable and valid baseline results for the given problem.

A Road to Aesthetic Stylistics

Full Text Available Being a linguistic phenomenon, poetry is marked by the defamilarization of language in a poetic discourse there is an aesthetic distortion of  the normal codes, in which the aesthetic value is the most prominent function of the poetic texture . This study is a new  adventure in correlating linguistics to aesthetics by and through the so-called approach Aesthetic stylistics( As. Aesthetic stylistics is the application of the theory of beauty to the intentionally violated components in literary text. It proceeds with the hypothesis that John Keats's Ode on a Grecian Urn and Kabbani's Maritime Poem are disinterested poetic experiences which create ecstatic responses to the reader's awareness, therefore, the judgment of the reader's taste is aesthetic. The study aims at highlighting the stylistic-aesthetic factors which generate the judgment of taste. While drawing heavily on the aestheticism of the Prague Linguistic Circle and Halliday's Functional Linguistics (FL, or what has come to be called the Traditional European Functionalism, the study will analyze Keats' Ode and Kabbani's poem in terms of Kant's Kritik der Urteilstraft, KdU. The two circles of the linguistic description and aesthetic interpretation will be internally interlinked to create the coherence of the stylistic process. The study consists of an introduction, two parts, one in theory and the other in analysis; it is eventually rounded up with concluding remarks elicited from the semiotic quest.  Keywords: Stylistics, Functionalism, Aesthetics

Graph Treewidth and Geometric Thickness Parameters

OpenAIRE

Dujmović, Vida; Wood, David R.

2005-01-01

Consider a drawing of a graph $G$ in the plane such that crossing edges are coloured differently. The minimum number of colours, taken over all drawings of $G$, is the classical graph parameter "thickness". By restricting the edges to be straight, we obtain the "geometric thickness". By further restricting the vertices to be in convex position, we obtain the "book thickness". This paper studies the relationship between these parameters and treewidth. Our first main result states that for grap...

Full Text Available In this article we will discuss how the aesthetic values, that the digital imaging provide, has influenced in drawing and architecture in a historical reading of the evolution of each means of architecture expression. In painting art and photography have been happening genres and styles that have adopted criteria of one or another discipline. When photography became independent from painting as an artistic discipline, its relationship to the architecture affected both the acceptance of its stylistic canon and the broadcast area. With technological development and the emergence of the new concept of digital imaging, it has become an indispensable tool in the whole process of contemporary architecture, which should not contaminate the true sense of the architectural drawing.

That is Cool: the Nature Of Aesthetics in Fluid Physics

Science.gov (United States)

Hertzberg, Jean

2013-11-01

Aesthetics has historically been defined as the study of beauty and thus as a metric of art. More recently, psychologists are using the term to describe a spectrum of responses from ``I hate it'' to ``I love it.'' In the context of fluid physics, what is beautiful? What elicits a ``Wow! Awesome! Cool!'' response versus a snore? Can we use aesthetics to deepen or change students' or the public's perceptions of physics and/or the world around them? For example, students seem to appreciate the aesthetics of destruction: environmental fluid dynamics such as storms, tornadoes, floods and wildfires are often responsible for massive destruction, yet humans draw pleasure from watching such physics and the attendant destruction from a safe distance. Can this voyeurism be turned to our advantage in communicating science? Observations of student and Facebook Flow Visualization group choices for fluid physics that draw a positive aesthetic response are sorted into empirical categories; the aesthetics of beauty, power, destruction, and oddness. Each aesthetic will be illustrated with examples drawn from flow visualizations from both the Flow Visualization course (MCEN 4151) taught at the University of Colorado, Boulder, and sources on the web.

PLOT3D (version-5): a computer code for drawing three dimensional graphs, maps and histograms, in single or multiple colours, for mono or stereoscopic viewing

International Nuclear Information System (INIS)

Jayaswal, Balhans

1987-01-01

PLOT3D series of graphic codes (version 1 to 5) have been developed for drawing three dimensional graphs, maps, histograms and simple layout diagrams on monochrome or colour raster graphic terminal and plotter. Of these, PLOT3D Version-5 is an advanced code, equipped with several features that make it specially suitable for drawing 3D maps, multicolour 3D and contour graphs, and 3D layout diagrams, in axonometric or perspective projection. Prior to drawing, graphic parameters that define orientation, magnification, smoothening, shading, colour-map, etc. of the figure can be selected interactively by means of simple commands on the user terminal, or by reading those commands from an input data file. This code requires linking with any one of three supporting libraries: PLOT 10 TCS, PLOT 10 IGL, and CALCOMP, and the figure can be plotted in single colour, or displayed in single or multiple colours depending upon the type of library support and output device. Furthermore, this code can also be used to plot left and right eye view projections of 3D figure for composing a stereoscopic image from them with the aid of a viewer. 14 figures. (author)

Planar graphs theory and algorithms

Nishizeki, T

1988-01-01

Collected in this volume are most of the important theorems and algorithms currently known for planar graphs, together with constructive proofs for the theorems. Many of the algorithms are written in Pidgin PASCAL, and are the best-known ones; the complexities are linear or 0(nlogn). The first two chapters provide the foundations of graph theoretic notions and algorithmic techniques. The remaining chapters discuss the topics of planarity testing, embedding, drawing, vertex- or edge-coloring, maximum independence set, subgraph listing, planar separator theorem, Hamiltonian cycles, and single- or multicommodity flows. Suitable for a course on algorithms, graph theory, or planar graphs, the volume will also be useful for computer scientists and graph theorists at the research level. An extensive reference section is included.

Unified Photo Enhancement by Discovering Aesthetic Communities From Flickr.

Hong, Richang; Zhang, Luming; Tao, Dacheng

2016-03-01

Photo enhancement refers to the process of increasing the aesthetic appeal of a photo, such as changing the photo aspect ratio and spatial recomposition. It is a widely used technique in the printing industry, graphic design, and cinematography. In this paper, we propose a unified and socially aware photo enhancement framework which can leverage the experience of photographers with various aesthetic topics (e.g., portrait and landscape). We focus on photos from the image hosting site Flickr, which has 87 million users and to which more than 3.5 million photos are uploaded daily. First, a tagwise regularized topic model is proposed to describe the aesthetic topic of each Flickr user, and coherent and interpretable topics are discovered by leveraging both the visual features and tags of photos. Next, a graph is constructed to describe the similarities in aesthetic topics between the users. Noticeably, densely connected users have similar aesthetic topics, which are categorized into different communities by a dense subgraph mining algorithm. Finally, a probabilistic model is exploited to enhance the aesthetic attractiveness of a test photo by leveraging the photographic experiences of Flickr users from the corresponding communities of that photo. Paired-comparison-based user studies show that our method performs competitively on photo retargeting and recomposition. Moreover, our approach accurately detects aesthetic communities in a photo set crawled from nearly 100000 Flickr users.

Summary: beyond fault trees to fault graphs

International Nuclear Information System (INIS)

Alesso, H.P.; Prassinos, P.; Smith, C.F.

1984-09-01

Fault Graphs are the natural evolutionary step over a traditional fault-tree model. A Fault Graph is a failure-oriented directed graph with logic connectives that allows cycles. We intentionally construct the Fault Graph to trace the piping and instrumentation drawing (P and ID) of the system, but with logical AND and OR conditions added. Then we evaluate the Fault Graph with computer codes based on graph-theoretic methods. Fault Graph computer codes are based on graph concepts, such as path set (a set of nodes traveled on a path from one node to another) and reachability (the complete set of all possible paths between any two nodes). These codes are used to find the cut-sets (any minimal set of component failures that will fail the system) and to evaluate the system reliability

The religion under the rule of aesthetics

2015-04-01

Full Text Available This article examines the modern process of aestheticization of culture and religion as consequent unfolding of the expansion of market rationality to the subjective life and the libidinal sphere of subjects. Its main objective is to inquire about the future of religion under the impact of sensation seeking culture and the inflation of aesthetics. Firstly, with the help of Türcke, Welsch, Foucault and Schultze´s investigate the aestheticization process of of social life, its causes and characteristics; Secondly, following Dufour, Türcke Leiss, Kline, Jhally e Welsch, it asks how the dynamics of aesthetical impacts the daily life and the bio-psychic economy of people; thirdly, it applies the results obtained to the analysis of what is happening with religion under the regime of aesthetics and sensational culture. Finally, it asks about the possible emancipatory potential of aestheticized own religious experience and tries to draw some further consequences for religion in the aesthetic field.

Information Technology and Aesthetics: Passive and Active Dimensions

Directory of Open Access Journals (Sweden)

John D Haynes

2007-09-01

Full Text Available This paper is concerned with examining and recognizing aesthetics in an Information System (an organization incorporating both humans and information technology. Aesthetics emerge from the wholeness of things, not from specific parts or components. As such, aesthetics may naturally be considered in “systems”, and we propose that an effective manner of thinking of aesthetics is to think in terms of “themes”. Humans have an extraordinary capacity to capture events thematically. In other words, human beings have a natural sense of aesthetics. To examine aesthetics in an information systems context, we argue that one must consider not only aesthetics that may be perceived by the senses (a passive dimension, but also aesthetics that may be conceived in the mind (an active dimension. This paper draws the conclusion that the benefits of aesthetics in relation to the study of Information Systems, has characteristics similar to the nature and importance of ethics in IS. Also, the study of aesthetics in IS has greater implications than simply recognizing and appreciating beauty and art. The very human capacity for recognizing and appreciating beauty and art is also the same capacity for effective creativity and happiness: the active aesthetic dimension. It follows that if an information system encouraged and provided the enabling circumstances for the human capacity of thematic recognition (as found in the human appreciation of art and beauty it thereby also provides the ground and the necessary thematically recognizable stimulus for effective creative and visionary organizational management.

Optimal Monotone Drawings of Trees

A monotone drawing of a graph G is a straight-line drawing of G such that, for every pair of vertices u,w in G, there exists abpath P_{uw} in G that is monotone in some direction l_{uw}. (Namely, the order of the orthogonal projections of the vertices of P_{uw} on l_{uw} is the same as the order they appear in P_{uw}.) The problem of finding monotone drawings for trees has been studied in several recent papers. The main focus is to reduce the size of the drawing. Currently, the smallest drawi...

PSYCHOANALYSIS AS APPLIED AESTHETICS.

Science.gov (United States)

Richmond, Stephen H

2016-07-01

The question of how to place psychoanalysis in relation to science has been debated since the beginning of psychoanalysis and continues to this day. The author argues that psychoanalysis is best viewed as a form of applied art (also termed applied aesthetics) in parallel to medicine as applied science. This postulate draws on a functional definition of modernity as involving the differentiation of the value spheres of science, art, and religion. The validity criteria for each of the value spheres are discussed. Freud is examined, drawing on Habermas, and seen to have erred by claiming that the psychoanalytic method is a form of science. Implications for clinical and metapsychological issues in psychoanalysis are discussed. © 2016 The Psychoanalytic Quarterly, Inc.

Can medicine be aesthetic? Disentangling beauty and health in elective surgeries.

Science.gov (United States)

Edmonds, Alexander

2013-06-01

This article analyzes tensions between aesthetics and health in medicine. The blurring of distinctions between reconstructive and cosmetic procedures, and the linking of plastic surgery with other medical treatments, have added to the legitimacy of an emerging "aesthetic medicine." As cosmetic surgeries become linked to other medical procedures with perceived greater medical necessity, health and aesthetics become entangled. One consequence is that medical needs are magnified while perceptions of the risks of surgery are minimized. Drawing on ethnographic work on plastic surgery, as well as other studies of obstetrics and cosmetic surgery, I illustrate this entanglement of health and aesthetics within the field of women's reproductive health care in Brazil. I argue that while it would be difficult to wholly disentangle aesthetics and health, analysis of how risk-benefit calculations are made in clinical practice offers a useful critical strategy for illuminating ethical problems posed by aesthetic medicine. © 2013 by the American Anthropological Association.

The spatial frequencies influence the aesthetic judgment of buildings transculturally.

Science.gov (United States)

Vannucci, Manila; Gori, Simone; Kojima, Haruyuki

2014-01-01

Recent evidence has shown that buildings designed to be high-ranking, according to the Western architectural decorum, have more impact on the minds of their beholders than low-ranking buildings. Here we investigated whether and how the aesthetic judgment for high- and low-ranking buildings was affected by differences in cultural expertise and by power spectrum differences. A group of Italian and Japanese participants performed aesthetic judgment tasks, with line drawings of high- and low-ranking buildings and with their random-phase versions (an image with the exact power spectrum of the original one but non-recognizable anymore). Irrespective of cultural expertise, high-ranking buildings and their relative random-phase versions received higher aesthetic judgments than low-ranking buildings and their random-phase versions. These findings indicate that high- and low-ranking buildings are differentiated for their aesthetic value and they show that low-level visual processes influence the aesthetic judgment based on differences in the stimuli power spectrum, irrespective of the influence of cultural expertise.

Psychotherapy in the aesthetic attitude.

Science.gov (United States)

Beebe, John

2010-04-01

Drawing upon the writings of Jungian analyst Joseph Henderson on unconscious attitudes toward culture that patients and analysts may bring to therapy, the author defines the aesthetic attitude as one of the basic ways that cultural experience is instinctively accessed and processed so that it can become part of an individual's self experience. In analytic treatment, the aesthetic attitude emerges as part of what Jung called the transcendent function to create new symbolic possibilities for the growth of consciousness. It can provide creative opportunities for new adaptation where individuation has become stuck in unconscious complexes, both personal and cultural. In contrast to formulations that have compared depth psychotherapy to religious ritual, philosophic discourse, and renewal of socialization, this paper focuses upon the considerations of beauty that make psychotherapy also an art. In psychotherapeutic work, the aesthetic attitude confronts both analyst and patient with the problem of taste, affects how the treatment is shaped and 'framed', and can grant a dimension of grace to the analyst's mirroring of the struggles that attend the patient's effort to be a more smoothly functioning human being. The patient may learn to extend the same grace to the analyst's fumbling attempts to be helpful. The author suggests that the aesthetic attitude is thus a help in the resolution of both countertransference and transference en route to psychological healing.

Graph-theoretical concepts and physicochemical data

Directory of Open Access Journals (Sweden)

Lionello Pogliani

2003-02-01

Full Text Available Graph theoretical concepts have been used to model the molecular polarizabilities of fifty-four organic derivatives, and the induced dipole moment of a set of fifty-seven organic compounds divided into three subsets. The starting point of these modeling strategies is the hydrogen-suppressed chemical graph and pseudograph of a molecule, which works very well for second row atoms. From these types of graphs a set of graph-theoretical basis indices, the molecular connectivity indices, can be derived and used to model properties and activities of molecules. With the aid of the molecular connectivity basis indices it is then possible to build higher-order descriptors. The problem of 'graph' encoding the contribution of the inner-core electrons of heteroatoms can here be solved with the aid of odd complete graphs, Kp-(p-odd. The use of these graph tools allow to draw an optimal modeling of the molecular polarizabilities and a satisfactory modeling of the induced dipole moment of a wide set of organic derivatives.

Drawing from the Deweyan theory of experience (1934, 1938), the goal of teaching and learning for transformative, aesthetic experience is contrasted against teaching and learning from a cognitive, rational framework. A quasi-experimental design was used to investigate teaching and learning of fifth grade science from each perspective across an entire school year including three major units of instruction. Detailed comparisons of teaching are given and pre and post measures of interest in learning science, science identity affiliation, and efficacy beliefs are investigated. Tests of conceptual understanding before, after, and one month after instruction reveal teaching for transformative, aesthetic experience fosters more, and more enduring, learning of science concepts. Investigations of transfer also suggest students learning for transformative, aesthetic experiences learn to see the world differently and find more interest and excitement in the world outside of school.

Full Text Available A. G. Baumgarten grounds the aesthetics of which he was the founder on widely poetic and rhetoric in his ‘Aestetica’ (1750/58. Nevertheless, what is significant here for him is to validate the individualist right of ‘sensitive knowledge.’ The word ‘aesthetics’ (αíσυŋгηικόç here is strictly attached to its basic meaning which is ‘related to sense and perception,’ and ‘sensually understandable.’ The aesthetics of Baumgarten is the philosophy of sensual knowledge and perception, and its sensitivity cannot be perceived as the material of outer stimulation and logic; contrarily, it sincerely sees it as a special genre of the knowledge. Hence, the aesthetics is defined as the ‘science of sensitive knowledge.’ With this study, it has been targeted to draw a general outline of Baumgarten’s aesthetics understanding by discussing the basic chapters of ‘Aestetica.’

Joint Graph Layouts for Visualizing Collections of Segmented Meshes

KAUST Repository

Ren, Jing

2017-09-12

We present a novel and efficient approach for computing joint graph layouts and then use it to visualize collections of segmented meshes. Our joint graph layout algorithm takes as input the adjacency matrices for a set of graphs along with partial, possibly soft, correspondences between nodes of different graphs. We then use a two stage procedure, where in the first step, we extend spectral graph drawing to include a consistency term so that a collection of graphs can be handled jointly. Our second step extends metric multi-dimensional scaling with stress majorization to the joint layout setting, while using the output of the spectral approach as initialization. Further, we discuss a user interface for exploring a collection of graphs. Finally, we show multiple example visualizations of graphs stemming from collections of segmented meshes and we present qualitative and quantitative comparisons with previous work.

Generating Realistic Labelled, Weighted Random Graphs

Directory of Open Access Journals (Sweden)

Michael Charles Davis

2015-12-01

Full Text Available Generative algorithms for random graphs have yielded insights into the structure and evolution of real-world networks. Most networks exhibit a well-known set of properties, such as heavy-tailed degree distributions, clustering and community formation. Usually, random graph models consider only structural information, but many real-world networks also have labelled vertices and weighted edges. In this paper, we present a generative model for random graphs with discrete vertex labels and numeric edge weights. The weights are represented as a set of Beta Mixture Models (BMMs with an arbitrary number of mixtures, which are learned from real-world networks. We propose a Bayesian Variational Inference (VI approach, which yields an accurate estimation while keeping computation times tractable. We compare our approach to state-of-the-art random labelled graph generators and an earlier approach based on Gaussian Mixture Models (GMMs. Our results allow us to draw conclusions about the contribution of vertex labels and edge weights to graph structure.

Defining the Aesthetic(s of Negation in El Techo de la Ballena

Directory of Open Access Journals (Sweden)

Sean Nesselrode

2014-06-01

Full Text Available The radical artist collective El Techo de la Ballena (1961–1968 is primarily remembered as a scandalous, interdisciplinary pioneer of performative public interventions in Venezuela. Yet the group established a contradictory, pluralistic visual aesthetic(s that served as a refusal of the artistic and political hegemony of geometric and kinetic art. This paper examines several case studies to consider El Techo’s complex visual output, which variously draws upon medieval woodcuts, photography and photomontage, and a mode of gestural abstraction that came to be known as informalismo. The group looked to an alternative genealogy of Dada and Surrealist tactics as a means of introducing an arsenal of new artistic strategies that could be adapted to a specifically Venezuelan discourse of development and disillusion. By advancing a visual language of unpredictability and mutability, El Techo actively refused to achieve a singular identity, its deliberate dissonances complementing its guerrilla approach to artmaking and ultimately seeking to undo the perceived academicism of dominant visualities in Venezuelan art and politics.

Recent research informing and related to the study of three-dimensional scientific models is assembled here in a way that explores an aesthetic, specifically, of touch. I concentrate on the materiality of models, drawing on insights from the history and philosophy of science, design and metaphysics. This article chronicles the ways in which touch, or material interactions, operate in the world of 3D models, and its role in what models mean and do. I end with a call for greater attention to scientific process, described as assembly of and within science, which is revealed by this focus on touch. Copyright © 2012 Elsevier Ltd.

Culture and aesthetic preference: comparing the attention to context of East Asians and Americans.

Science.gov (United States)

Masuda, Takahiko; Gonzalez, Richard; Kwan, Letty; Nisbett, Richard E

2008-09-01

Prior research indicates that East Asians are more sensitive to contextual information than Westerners. This article explored aesthetics to examine whether cultural variations were observable in art and photography. Study 1 analyzed traditional artistic styles using archival data in representative museums. Study 2 investigated how contemporary East Asians and Westerners draw landscape pictures and take portrait photographs. Study 3 further investigated aesthetic preferences for portrait photographs. The results suggest that (a) traditional East Asian art has predominantly context-inclusive styles, whereas Western art has predominantly object-focused styles, and (b) contemporary members of East Asian and Western cultures maintain these culturally shaped aesthetic orientations. The findings can be explained by the relation among attention, cultural resources, and aesthetic preference.

Teaching 5th grade science for aesthetic understanding

Science.gov (United States)

Girod, Mark A.

Many scientists speak with great zeal about the role of aesthetics and beauty in their science and inquiry. Few systematic efforts have been made to teach science in ways that appeal directly to aesthetics and this research is designed to do just that. Drawing from the aesthetic theory of Dewey, I describe an analytic lens called learning for aesthetic understanding that finds power in the degree to which our perceptions of the world are transformed, our interests and enthusiasm piqued, and our actions changed as we seek further experiences in the world. This learning theory is contrasted against two other current and popular theories of science learning, that of learning for conceptual understanding via conceptual change theory and learning for a language-oriented or discourse-based understanding. After a lengthy articulation of the pedagogical strategies used to teach for aesthetic understanding the research is described in which comparisons are drawn between students in two 5th grade classrooms---one taught for the goal of conceptual understanding and the other taught for the goal of aesthetic understanding. Results of this comparison show that more students in the treatment classroom had aesthetic experiences with science ideas and came to an aesthetic understanding when studying weather, erosion, and structure of matter than students in the control group. Also statistically significant effects are shown on measures of interest, affect, and efficacy for students in the treatment class. On measures of conceptual understanding it appears that treatment class students learned more and forgot less over time than control class students. The effect of the treatment does not generally depend on gender, ethnicity, or prior achievement except in students' identity beliefs about themselves as science learners. In this case, a significant interaction for treatment class females on science identity beliefs did occur. A discussion of these results as well as elaboration and

Ten years of a model of aesthetic appreciation and aesthetic judgments : The aesthetic episode - Developments and challenges in empirical aesthetics.

Science.gov (United States)

Leder, Helmut; Nadal, Marcos

2014-11-01

About a decade ago, psychology of the arts started to gain momentum owing to a number of drives: technological progress improved the conditions under which art could be studied in the laboratory, neuroscience discovered the arts as an area of interest, and new theories offered a more comprehensive look at aesthetic experiences. Ten years ago, Leder, Belke, Oeberst, and Augustin (2004) proposed a descriptive information-processing model of the components that integrate an aesthetic episode. This theory offered explanations for modern art's large number of individualized styles, innovativeness, and for the diverse aesthetic experiences it can stimulate. In addition, it described how information is processed over the time course of an aesthetic episode, within and over perceptual, cognitive and emotional components. Here, we review the current state of the model, and its relation to the major topics in empirical aesthetics today, including the nature of aesthetic emotions, the role of context, and the neural and evolutionary foundations of art and aesthetics. © 2014 The British Psychological Society.

Cajal’s hypothetical mapping of the neurological forest through histology drawings

Directory of Open Access Journals (Sweden)

José María Ariso, PhD

2017-07-01

Full Text Available One of the most significant steps taken to further the intimacy between medicine and art was taken by Santiago Ramón y Cajal, who was subsequently regarded as the father of modern neuroscience. In the late 19th century, Cajal started to draw neural tissues, and neurons in detail. As paradoxical as it may seem, the aesthetic quality of his drawings was so substantial that, in principle, they were not taken seriously by most of Cajal’s professional colleagues. However, they were eventually proven wrong, and today Cajal’s sketches are known for their brilliant clarity and accuracy. Indeed, in this article I provide a brief account of the scientific, aesthetic and even ethical relevance of Cajal’s work, which ended up holding pride of place in the history of medicine.

Aesthetic perception and judgement are not merely cognitive processes, but also involve feelings. Therefore, the empirical study of these experiences requires conceptualization and measurement of aesthetic emotions. Despite the long-standing interest in such emotions, we still lack an assessment tool to capture the broad range of emotions that occur in response to the perceived aesthetic appeal of stimuli. Elicitors of aesthetic emotions are not limited to the arts in the strict sense, but extend to design, built environments, and nature. In this article, we describe the development of a questionnaire that is applicable across many of these domains: the Aesthetic Emotions Scale (Aesthemos). Drawing on theoretical accounts of aesthetic emotions and an extensive review of extant measures of aesthetic emotions within specific domains such as music, literature, film, painting, advertisements, design, and architecture, we propose a framework for studying aesthetic emotions. The Aesthemos, which is based on this framework, contains 21 subscales with two items each, that are designed to assess the emotional signature of responses to stimuli’s perceived aesthetic appeal in a highly differentiated manner. These scales cover prototypical aesthetic emotions (e.g., the feeling of beauty, being moved, fascination, and awe), epistemic emotions (e.g., interest and insight), and emotions indicative of amusement (humor and joy). In addition, the Aesthemos subscales capture both the activating (energy and vitality) and the calming (relaxation) effects of aesthetic experiences, as well as negative emotions that may contribute to aesthetic displeasure (e.g., the feeling of ugliness, boredom, and confusion).

Localization in random bipartite graphs: Numerical and empirical study

Science.gov (United States)

Slanina, František

2017-05-01

We investigate adjacency matrices of bipartite graphs with a power-law degree distribution. Motivation for this study is twofold: first, vibrational states in granular matter and jammed sphere packings; second, graphs encoding social interaction, especially electronic commerce. We establish the position of the mobility edge and show that it strongly depends on the power in the degree distribution and on the ratio of the sizes of the two parts of the bipartite graph. At the jamming threshold, where the two parts have the same size, localization vanishes. We found that the multifractal spectrum is nontrivial in the delocalized phase, but still near the mobility edge. We also study an empirical bipartite graph, namely, the Amazon reviewer-item network. We found that in this specific graph the mobility edge disappears, and we draw a conclusion from this fact regarding earlier empirical studies of the Amazon network.

A gray matter of taste: sound perception, music cognition, and Baumgarten's aesthetics.

Science.gov (United States)

Pannese, Alessia

2012-09-01

Music is an ancient and ubiquitous form of human expression. One important component for which music is sought after is its aesthetic value, whose appreciation has typically been associated with largely learned, culturally determined factors, such as education, exposure, and social pressure. However, neuroscientific evidence shows that the aesthetic response to music is often associated with automatic, physically- and biologically-grounded events, such as shivers, chills, increased heart rate, and motor synchronization, suggesting the existence of an underlying biological platform upon which contextual factors may act. Drawing on philosophical notions and neuroscientific evidence, I argue that, although there is no denying that social and cultural context play a substantial role in shaping the aesthetic response to music, these act upon largely universal, biological mechanisms involved with neural processing. I propose that the simultaneous presence of culturally-influenced and biologically-determined contributions to the aesthetic response to music epitomizes Baumgarten's equation of sensory perception with taste. Taking the argument one step further, I suggest that the heavily embodied aesthetic response to music bridges the cleavage between the two discrepant meanings-the one referring to sensory perception, the other referring to judgments of taste-traditionally attributed to the word "aesthetics" in the sciences and the humanities.

Aesthetic Response and Cosmic Aesthetic Distance

Science.gov (United States)

Madacsi, D.

2013-04-01

For Homo sapiens, the experience of a primal aesthetic response to nature was perhaps a necessary precursor to the arousal of an artistic impulse. Among the likely visual candidates for primal initiators of aesthetic response, arguments can be made in favor of the flower, the human face and form, and the sky and light itself as primordial aesthetic stimulants. Although visual perception of the sensory world of flowers and human faces and forms is mediated by light, it was most certainly in the sky that humans first could respond to the beauty of light per se. It is clear that as a species we do not yet identify and comprehend as nature, or part of nature, the entire universe beyond our terrestrial environs, the universe from which we remain inexorably separated by space and time. However, we now enjoy a technologically-enabled opportunity to probe the ultimate limits of visual aesthetic distance and the origins of human aesthetic response as we remotely explore deep space via the Hubble Space Telescope and its successors.

Aesthetic and emotional effects of meter and rhyme in poetry.

Metrical patterning and rhyme are frequently employed in poetry but also in infant-directed speech, play, rites, and festive events. Drawing on four line-stanzas from nineteenth and twentieth German poetry that feature end rhyme and regular meter, the present study tested the hypothesis that meter and rhyme have an impact on aesthetic liking, emotional involvement, and affective valence attributions. Hypotheses that postulate such effects have been advocated ever since ancient rhetoric and poetics, yet they have barely been empirically tested. More recently, in the field of cognitive poetics, these traditional assumptions have been readopted into a general cognitive framework. In the present experiment, we tested the influence of meter and rhyme as well as their interaction with lexicality in the aesthetic and emotional perception of poetry. Participants listened to stanzas that were systematically modified with regard to meter and rhyme and rated them. Both rhyme and regular meter led to enhanced aesthetic appreciation, higher intensity in processing, and more positively perceived and felt emotions, with the latter finding being mediated by lexicality. Together these findings clearly show that both features significantly contribute to the aesthetic and emotional perception of poetry and thus confirm assumptions about their impact put forward by cognitive poetics. The present results are explained within the theoretical framework of cognitive fluency, which links structural features of poetry with aesthetic and emotional appraisal.

Aesthetic chills: Knowledge-acquisition, meaning-making and aesthetic emotions

Directory of Open Access Journals (Sweden)

Leonid Perlovsky

2016-08-01

Full Text Available This article addresses the relation between aesthetic emotions, knowledge-acquisition, and meaning-making. We briefly review theoretical foundations and present experimental data related to aesthetic chills. These results suggest that aesthetic chills are inhibited by exposing the subject to an incoherent prime prior to the chill-eliciting stimulation, and that a meaningful prime makes the aesthetic experience more pleasurable than a neutral or an incoherent one. Aesthetic chills induced by narrative structures seem to be related to the pinnacle of the story, to have a significant calming effect and subjects describe a strong empathy for the characters. We discuss the relation between meaning-making and aesthetic emotions at the psychological, physiological, narratological, and mathematical levels and propose a series of hypotheses to be tested in future research.

Eigenfunction statistics on quantum graphs

International Nuclear Information System (INIS)

Gnutzmann, S.; Keating, J.P.; Piotet, F.

2010-01-01

We investigate the spatial statistics of the energy eigenfunctions on large quantum graphs. It has previously been conjectured that these should be described by a Gaussian Random Wave Model, by analogy with quantum chaotic systems, for which such a model was proposed by Berry in 1977. The autocorrelation functions we calculate for an individual quantum graph exhibit a universal component, which completely determines a Gaussian Random Wave Model, and a system-dependent deviation. This deviation depends on the graph only through its underlying classical dynamics. Classical criteria for quantum universality to be met asymptotically in the large graph limit (i.e. for the non-universal deviation to vanish) are then extracted. We use an exact field theoretic expression in terms of a variant of a supersymmetric σ model. A saddle-point analysis of this expression leads to the estimates. In particular, intensity correlations are used to discuss the possible equidistribution of the energy eigenfunctions in the large graph limit. When equidistribution is asymptotically realized, our theory predicts a rate of convergence that is a significant refinement of previous estimates. The universal and system-dependent components of intensity correlation functions are recovered by means of an exact trace formula which we analyse in the diagonal approximation, drawing in this way a parallel between the field theory and semiclassics. Our results provide the first instance where an asymptotic Gaussian Random Wave Model has been established microscopically for eigenfunctions in a system with no disorder.

[Exploration of nursing art and aesthetic experiences: cross-disciplinary links and dialogues].

Interdisciplinary understanding is crucial for readers today. This article integrates the ideas of four care-aesthetics-column writers in order to illustrate and discuss nursing art and aesthetic care experiences in a cross-disciplinary conversation. This article reflects critically on the art, culture, and nature of nursing in the five themes of: 1) the shape of nursing knowledge, "science" or "art"?; 2) the caring arts: passively regulative or consciously creative labor?; 3) busy hospital workers: a landscape of persons and objects or the creators of the scenery?; 4) nursing skills, arts, and the Tao; and 5) art liberation: is the nursing profession in need of a revolution or fundamental reform? This article utilizes diverse and occasionally contradictory points of view together with practical examples in order to encourage readers to interlink their disparate professional nursing skills and draw aesthetic knowledge from multiple sources and experiences.

Aesthetic aspects in meaning making - an explorative study of dance education in a PETE programme

Directory of Open Access Journals (Sweden)

Suzanne Lundvall

2010-12-01

Full Text Available The article focuses on how aesthetic aspects of experience are involved in meaning making within an educational setting of body movement practice. The study explores stories of how physical education student teachers feel when participating in a dance lesson, with attention given to aesthetic aspects of embodied experiences in relation to meaning making. The study draws on Dewey’s theory of experimental learning. Aesthetic experience is defined as the feeling of wholeness or fulfilment in the transaction taking place. The categorical analysis of content, inspired by pragmatic epistemology analyses, uses the operational concepts of gaps, encounters, and relations. Three categories of stories emerge linked by the resemblance of positive or negative feelings expressed. The aesthetic experiences seem to inform the students of the purpose of what is undertaken, how to value the experience, and how the meaning of the embodied experience is perceived.

Brain and Aesthetic Attitude: How to Integrate "Old" and "New" Aesthetics

Directory of Open Access Journals (Sweden)

Gianluca Consoli

2014-01-01

Full Text Available At present, various efforts are being put forward to naturalize aesthetics. One of the most controversial disciplines of aesthetics is neuroaesthetics. The first applications of neuroimaging of the aesthetic experience of paintings occurred ten years ago. Over this decade, neuroscientific findings have determined three common centers of visual aesthetic experience: top-down processing; reward and evaluation; and cortical sensory processing. Undoubtedly, these common centers require better identification and further investigation. However, the experimental data currently available make it possible to falsify or corroborate traditional philosophical theories of aesthetic perception and evaluation. Within an integrated approach to aesthetics, this selective function might constitute a future role for neuroaesthetics in humanities research.

Wollina, Uwe; Payne, Christopher Rowland

2010-03-01

The western world is getting older. Aging well has become the new target of preventative medicine. Aesthetic dermatology can contribute to this quest. Females over 65 represent an important and growing group of consumers of cosmetic procedures. In this group, there is a paucity of scientific evaluation of aesthetic procedures. To review the use of minimally invasive procedures for facial rejuvenation in women over 65. Drawing from both the literature and personal experience, the opportunities, modifications, and limitations of minimally invasive techniques for facial rejuvenation in older women are considered. In this older age group, dermal fillers, chemical and laser peels, and nonablative photorejuvenation remain useful and can each be used as stand-alone treatments. In this age group, botulinum toxin (BTX) injections are more often used in combination with other procedures. With respect to aesthetic procedures, women over 65 are different from younger women. More scientific investigation is necessary to better meet needs of this growing part of the population. Available data suggest that aesthetic dermatology can make a major contribution to the complex matter of aging well.

Full Text Available Abstract Background With continuing identification of novel structured noncoding RNAs, there is an increasing need to create schematic diagrams showing the consensus features of these molecules. RNA structural diagrams are typically made either with general-purpose drawing programs like Adobe Illustrator, or with automated or interactive programs specific to RNA. Unfortunately, the use of applications like Illustrator is extremely time consuming, while existing RNA-specific programs produce figures that are useful, but usually not of the same aesthetic quality as those produced at great cost in Illustrator. Additionally, most existing RNA-specific applications are designed for drawing single RNA molecules, not consensus diagrams. Results We created R2R, a computer program that facilitates the generation of aesthetic and readable drawings of RNA consensus diagrams in a fraction of the time required with general-purpose drawing programs. Since the inference of a consensus RNA structure typically requires a multiple-sequence alignment, the R2R user annotates the alignment with commands directing the layout and annotation of the RNA. R2R creates SVG or PDF output that can be imported into Adobe Illustrator, Inkscape or CorelDRAW. R2R can be used to create consensus sequence and secondary structure models for novel RNA structures or to revise models when new representatives for known RNA classes become available. Although R2R does not currently have a graphical user interface, it has proven useful in our efforts to create 100 schematic models of distinct noncoding RNA classes. Conclusions R2R makes it possible to obtain high-quality drawings of the consensus sequence and structural models of many diverse RNA structures with a more practical amount of effort.

Dynamics of aesthetic appreciation

Science.gov (United States)

Carbon, Claus-Christian

2012-03-01

Aesthetic appreciation is a complex cognitive processing with inherent aspects of cold as well as hot cognition. Research from the last decades of empirical has shown that evaluations of aesthetic appreciation are highly reliable. Most frequently, facial attractiveness was used as the corner case for investigating aesthetic appreciation. Evaluating facial attractiveness shows indeed high internal consistencies and impressively high inter-rater reliabilities, even across cultures. Although this indicates general and stable mechanisms underlying aesthetic appreciation, it is also obvious that our taste for specific objects changes dynamically. Aesthetic appreciation on artificial object categories, such as fashion, design or art is inherently very dynamic. Gaining insights into the cognitive mechanisms that trigger and enable corresponding changes of aesthetic appreciation is of particular interest for research as this will provide possibilities to modeling aesthetic appreciation for longer durations and from a dynamic perspective. The present paper refers to a recent two-step model ("the dynamical two-step-model of aesthetic appreciation"), dynamically adapting itself, which accounts for typical dynamics of aesthetic appreciation found in different research areas such as art history, philosophy and psychology. The first step assumes singular creative sources creating and establishing innovative material towards which, in a second step, people adapt by integrating it into their visual habits. This inherently leads to dynamic changes of the beholders' aesthetic appreciation.

Conceptualizing Aesthetics in Design

Folkmann, Mads Nygaard

2018-01-01

The aim of this chapter is to introduce and discuss aesthetics as an approach to understand how design frames experience. In doing so, the chapter combines two philosophical interests in design, design phenomenology and design aesthetics, in order to promote a framework for discussing the impact...... of aesthetic meaning construction on experience. First, the chapter raises the phenomenological question of the relationship between design and experience, specifically, how design conditions experience. Second, in looking at aesthetics in terms of a) the sensual appeal of design, b) design objects...... as aesthetic media that frame modes of understanding, and c) contextual factors, such as media, influencing what is regarded as aesthetic, it is the thesis of the chapter that a reflective concept of design aesthetics can be employed to differentiate between three different ways in which design frame our...

Using Graph and Vertex Entropy to Compare Empirical Graphs with Theoretical Graph Models

Directory of Open Access Journals (Sweden)

Tomasz Kajdanowicz

2016-09-01

Full Text Available Over the years, several theoretical graph generation models have been proposed. Among the most prominent are: the Erdős–Renyi random graph model, Watts–Strogatz small world model, Albert–Barabási preferential attachment model, Price citation model, and many more. Often, researchers working with real-world data are interested in understanding the generative phenomena underlying their empirical graphs. They want to know which of the theoretical graph generation models would most probably generate a particular empirical graph. In other words, they expect some similarity assessment between the empirical graph and graphs artificially created from theoretical graph generation models. Usually, in order to assess the similarity of two graphs, centrality measure distributions are compared. For a theoretical graph model this means comparing the empirical graph to a single realization of a theoretical graph model, where the realization is generated from the given model using an arbitrary set of parameters. The similarity between centrality measure distributions can be measured using standard statistical tests, e.g., the Kolmogorov–Smirnov test of distances between cumulative distributions. However, this approach is both error-prone and leads to incorrect conclusions, as we show in our experiments. Therefore, we propose a new method for graph comparison and type classification by comparing the entropies of centrality measure distributions (degree centrality, betweenness centrality, closeness centrality. We demonstrate that our approach can help assign the empirical graph to the most similar theoretical model using a simple unsupervised learning method.

A New Kind of Aesthetics —The Mathematical Structure of the Aesthetic

Full Text Available This paper proposes a new approach to the investigation into aesthetics. Specifically, it~argues that it is possible to explain the aesthetic and its underlying dynamic relations with an~axiomatic structure (the octahedral axiom-derived category based on contemporary mathematics (namely category theory, and through this argument suggests the possibility for discussion about the mathematical structure of the aesthetic. If there were a way to describe the structure of the aesthetic with the language of mathematical structures and mathematical axioms---a~language completely devoid of arbitrariness---then we would make possible a universal argument about the essential human activity of ``the aesthetic'', and we would also gain a new method and viewpoint into the philosophy and meaning of the act of creating a work of art and artistic activities. This paper presents one mathematical structure as a foundation in constructing the science of dynamic aesthetics based on axiomatic functionalism, which is in turn based on a new interdisciplinary investigation into the generative structure of the aesthetic.

‘Machinic Trajectories’: Appropriated Devices as Post-Digital Drawing Machines

Directory of Open Access Journals (Sweden)

Andres Wanner

2014-12-01

Full Text Available This article presents a series of works called Machinic Trajectories, consisting of domestic devices appropriated as mechanical drawing machines. These are contextualized within the post-digital discourse, which integrates messy analog conditions into the digital realm. The role of eliciting and examining glitches for investigating a technology is pointed out. Glitches are defined as short-lived, unpremeditated aesthetic results of a failure; they are mostly known as digital phenomena, but I argue that the concept is equally applicable to the output of mechanical machines. Three drawing machines will be presented: The Opener, The Mixer and The Ventilator. In analyzing their drawings, emergent patterns consisting of unpremeditated visual artifacts will be identified and connected to irregularities of the specific technologies. Several other artists who work with mechanical and robotic drawing machines are introduced, to situate the presented works and reflections in a larger context of practice and to investigate how glitch concepts are applicable to such mechanical systems.

2014-07-01

Full Text Available The article analyses deconstructions of the European construct from the vantage point of how skin colour, physical appearance and religion have been used for drawing boundaries between white, Christian Europe and the black, Muslim world. The analysis is based on literary texts by the Afro-Swedish author Johannes Anyuru. The article proposes that his first collection of poems from 2003, the first novel from 2010 and a multifaceted text from 2011, which is a kind of diary on the surface level, contribute to the shaping of new notions of belonging, home and identity that challenge ideas of cultural purity and homogeneity. On the level of aesthetics the texts exemplify a diaspora aesthetic characterized by hybridization. This involves a mixture of elements from various stylistic registers and locations from within and outside Europe.

Integrated color face graphs for plant accident display

International Nuclear Information System (INIS)

Hara, Fumio

1987-01-01

This paper presents an integrated man-machine interface that uses cartoon-like colored graphs in the form of faces, that, through different facial expressions, display a plant condition. This is done by drawing the face on a CRT by nonlinearly transforming 31 variables and coloring the face. This integrated color graphics technique is applied to display the progess of events in the Three Mile Island nuclear power plant accident. Human visual perceptive characteristics are investigated in relation to the perception of the plant accident process, the naturality in face color change, and the consistency between facial expressions and colors. This paper concludes that colors used in an integrated color face graphs must be completely consistent with emotional feelings perceived from the colors. (author)

Aesthetic experience of dance performances

Directory of Open Access Journals (Sweden)

Vukadinović Maja

2012-01-01

Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

Maintaining "Synk" in Detroit: Two Case Studies in the Remix Aesthetic

Directory of Open Access Journals (Sweden)

Carleton S. Gholz

2011-03-01

Full Text Available Advances in audio-visual remixing technologies have produced a significant, largely unintended, consequence: audiences at EDM performances are dancing less—if at all. Instead, utilizing digital mobile devices, audiences have increasingly become interactive media producers within an environment encouraged by savvy, former DJs. Drawing from the fields of EDM studies, sound studies and film studies, I outline the historical arc of the remix aesthetic by comparing and contrasting recent work by two long-time EDM artists from the Detroit-Windsor region, Jeff Mills and Richie Hawtin. These two artists were central to the global proliferation of EDM culture during its mass-communication phase. However, in an era of heightened media convergence what scholars have traditionally understood as EDM has irreparably changed. Mills and Hawtin have much to contribute to this apparent impasse.Keywords: EDM, film studies, film sound, remix aesthetic, soundscape, media convergence, Jeff Mills, Richie Hawtin, Plastikman

Antonak, R F

1990-01-01

While this product is clearly unique, its usefulness to individuals outside small business environments is somewhat limited. FlexiGraphs is, however, a reasonable first attempt to design a microcomputer software package that controls data through interactive editing within a graph. Although the graphics capabilities of mainframe programs such as MINITAB (Ryan, Joiner, & Ryan, 1981) and the graphic manipulations available through exploratory data analysis (e.g., Velleman & Hoaglin, 1981) will not be surpassed anytime soon by this program, a researcher may want to add this program to a software library containing other Macintosh statistics, drawing, and graphics programs if only to obtain the easy-to-obtain curve fitting and line smoothing options. I welcome the opportunity to review the enhanced "scientific" version of FlexiGraphs that the author of the program indicates is currently under development. An MS-DOS version of the program should be available within the year.

Esteetilise suhtumise mõiste Nõukogude Eesti esteetikas. The Concept of Aesthetic Approach in Soviet Estonian Aesthetics

Directory of Open Access Journals (Sweden)

Marek Volt

2012-04-01

Full Text Available This nostalgic yet analytic article discusses the topic of aesthetic approach in the aesthetic literature of Soviet Estonia (authors Borev, Kagan, Stolovich and others. Firstly, the aesthetic approach engages man’s creative/reshaping activities in relation to the world (following Marx’s slogan that ’man also produces in accordance with the laws of beauty’. Secondly, an artistic meaning can be distinguished, followed by a third, the subjective aesthetic meaning, which indicates the actual application of aesthetic categories (such as ’beauty’, ’sublimity’, etc.. Since the subjective aesthetic meaning is fundamental in relation to the other meanings, the article focuses on the specific characterisation of this category. The first important characteristic is the appraisability, which is born from the usage of the categories; the number of categories has been subject to historical change, reflecting the development of man’s aesthetic approach. Aesthetic approach was mainly defined through the five conditions (sensuousness, direct contact with the concrete object, selflessness, and the appraisal of the object in comparison with the ideal. Analysis of the aesthetic approach in a historical dialectic relation to theoretical, utilitarian and ethical approaches indicates that aesthetical feelings only arose towards the end of the Paleolithic era. Peoples on a lower developmental level didn’t know of aesthetic appraisal, or their aesthetic appraisals were still very closely connected with the utilitaristic. Even though all approaches at times are exhibited in their ‘pure’ forms, Soviet aesthetics generally held to the opinion that they arose simultaneously in daily practice and were intertwined with one another. The societal and practical meanings are what constitute the aesthetic approach – meaning that they define what man will begin to consider beautiful (in its more radical forms, this meant reducing the beauty of an object to

Sonic morphology: Aesthetic dimensional auditory spatial awareness

Science.gov (United States)

Whitehouse, Martha M.

The sound and ceramic sculpture installation, " Skirting the Edge: Experiences in Sound & Form," is an integration of art and science demonstrating the concept of sonic morphology. "Sonic morphology" is herein defined as aesthetic three-dimensional auditory spatial awareness. The exhibition explicates my empirical phenomenal observations that sound has a three-dimensional form. Composed of ceramic sculptures that allude to different social and physical situations, coupled with sound compositions that enhance and create a three-dimensional auditory and visual aesthetic experience (see accompanying DVD), the exhibition supports the research question, "What is the relationship between sound and form?" Precisely how people aurally experience three-dimensional space involves an integration of spatial properties, auditory perception, individual history, and cultural mores. People also utilize environmental sound events as a guide in social situations and in remembering their personal history, as well as a guide in moving through space. Aesthetically, sound affects the fascination, meaning, and attention one has within a particular space. Sonic morphology brings art forms such as a movie, video, sound composition, and musical performance into the cognitive scope by generating meaning from the link between the visual and auditory senses. This research examined sonic morphology as an extension of musique concrete, sound as object, originating in Pierre Schaeffer's work in the 1940s. Pointing, as John Cage did, to the corporeal three-dimensional experience of "all sound," I composed works that took their total form only through the perceiver-participant's participation in the exhibition. While contemporary artist Alvin Lucier creates artworks that draw attention to making sound visible, "Skirting the Edge" engages the perceiver-participant visually and aurally, leading to recognition of sonic morphology.

A dual-process perspective on fluency-based aesthetics: the pleasure-interest model of aesthetic liking.

Science.gov (United States)

Graf, Laura K M; Landwehr, Jan R

2015-11-01

In this article, we develop an account of how aesthetic preferences can be formed as a result of two hierarchical, fluency-based processes. Our model suggests that processing performed immediately upon encountering an aesthetic object is stimulus driven, and aesthetic preferences that accrue from this processing reflect aesthetic evaluations of pleasure or displeasure. When sufficient processing motivation is provided by a perceiver's need for cognitive enrichment and/or the stimulus' processing affordance, elaborate perceiver-driven processing can emerge, which gives rise to fluency-based aesthetic evaluations of interest, boredom, or confusion. Because the positive outcomes in our model are pleasure and interest, we call it the Pleasure-Interest Model of Aesthetic Liking (PIA Model). Theoretically, this model integrates a dual-process perspective and ideas from lay epistemology into processing fluency theory, and it provides a parsimonious framework to embed and unite a wealth of aesthetic phenomena, including contradictory preference patterns for easy versus difficult-to-process aesthetic stimuli. © 2015 by the Society for Personality and Social Psychology, Inc.

Literary aesthetics: beauty, the brain, and Mrs. Dalloway.

Science.gov (United States)

Hogan, Patrick Colm

2013-01-01

Empirical research indicates that beauty is in part a matter of prototype approximation. Some research suggests that unanticipated pattern recognition is important as well. This essay begins by briefly outlining an account of beauty based on these factors. It goes on to consider complications. Minor complications include the partial incompatibility of these accounts and the importance of differentiating judgments of beauty from aesthetic response. More serious issues include the relative neglect of literature in neurologically-based discussions of beauty, which tend to focus on music or visual art. There is also a relative neglect of emotion, beyond the reward system. Finally, there is the almost complete absence of the sublime. After considering these problems broadly, the essay turns to Virginia Woolf's Mrs. Dalloway, examining its treatment of beauty and sublimity. The aim of this section is not merely to illuminate Woolf's novel by reference to neuroscientific research. It is equally, perhaps more fully, to expand our neuroscientifically grounded account of aesthetic response by drawing on Woolf's novel. In Mrs. Dalloway, there are gestures toward prototypes and patterns in beauty. But the key features are clearly emotional. Specifically, the emotions at issue in feelings of beauty and sublimity appear to be primarily attachment, on the one hand, and a profound sense of isolation, on the other. Woolf's novel also points us toward other features of aesthetic experience, crucially including the emotion-sharing that is a key function of the production and circulation of art. © 2013 Elsevier B.V.

Image-guided automatic triggering of a fractional CO2 laser in aesthetic procedures.

Science.gov (United States)

Wilczyński, Sławomir; Koprowski, Robert; Wiernek, Barbara K; Błońska-Fajfrowska, Barbara

2016-09-01

Laser procedures in dermatology and aesthetic medicine are associated with the need for manual laser triggering. This leads to pulse overlapping and side effects. Automatic laser triggering based on image analysis can provide a secure fit to each successive doses of radiation. A fractional CO2 laser was used in the study. 500 images of the human skin of healthy subjects were acquired. Automatic triggering was initiated by an application together with a camera which tracks and analyses the skin in visible light. The tracking algorithm uses the methods of image analysis to overlap images. After locating the characteristic points in analysed adjacent areas, the correspondence of graphs is found. The point coordinates derived from the images are the vertices of graphs with respect to which isomorphism is sought. When the correspondence of graphs is found, it is possible to overlap the neighbouring parts of the image. The proposed method of laser triggering owing to the automatic image fitting method allows for 100% repeatability. To meet this requirement, there must be at least 13 graph vertices obtained from the image. For this number of vertices, the time of analysis of a single image is less than 0.5s. The proposed method, applied in practice, may help reduce the number of side effects during dermatological laser procedures resulting from laser pulse overlapping. In addition, it reduces treatment time and enables to propose new techniques of treatment through controlled, precise laser pulse overlapping. Copyright © 2016 Elsevier Ltd. All rights reserved.

Crafty Entanglements: Knitting and Hard Distinctions in Aesthetics and Political Theory

Directory of Open Access Journals (Sweden)

Kate M. Daley

2013-01-01

Full Text Available Many theoretical writings on aesthetics and politics rely on hard distinctions between what is and is not art, and what is and is not political. In this article, I draw on the work of theorists, knitters, and fiber artists to argue that hand knitting provides a lens through which to unsettle some of these distinctions. I illustrate some of the ways in which aesthetic theory relies on hard distinctions between art and not-art and politics and not-politics, with particular focus on the work of Kant, Hegel, Heidegger, and Rancière. I explain how knitting is often seen as falling clearly outside the definitions of art and politics, and explore the surprising ways in which knitting shows the instability of these categories and expectations. I show that common social traditions and practices that often go unanalyzed can provide insight into the limitations and complexities of prevalent theoretical assumptions.

Proxy Graph: Visual Quality Metrics of Big Graph Sampling.

Science.gov (United States)

Nguyen, Quan Hoang; Hong, Seok-Hee; Eades, Peter; Meidiana, Amyra

2017-06-01

Data sampling has been extensively studied for large scale graph mining. Many analyses and tasks become more efficient when performed on graph samples of much smaller size. The use of proxy objects is common in software engineering for analysis and interaction with heavy objects or systems. In this paper, we coin the term 'proxy graph' and empirically investigate how well a proxy graph visualization can represent a big graph. Our investigation focuses on proxy graphs obtained by sampling; this is one of the most common proxy approaches. Despite the plethora of data sampling studies, this is the first evaluation of sampling in the context of graph visualization. For an objective evaluation, we propose a new family of quality metrics for visual quality of proxy graphs. Our experiments cover popular sampling techniques. Our experimental results lead to guidelines for using sampling-based proxy graphs in visualization.

On the aesthetic illusion.

Science.gov (United States)

Balter, L

1999-01-01

The aesthetic illusion--the experience of the content of a work of art as reality--occurs through the mobilization and intensification of typical infantile fantasies in the beholder. This necessarily evokes intrapsychic conflict in the mature adult. Two illusion-producing strategies ameliorate this conflict and effect the aesthetic illusion. The first illusion is that the artist's proffered fantasy is the beholder's own personal and private fantasy. This isolates the beholder from the shame- and guilt-evoking social surround. The second illusion is that the protagonist depicted in the work is an actual person. This defends the beholder from the painful emotions attendant upon his instinctually gratifying identification with the protagonist. The first illusion is necessary for the establishment of the second, but it is the second that establishes the aesthetic illusion. The aesthetic illusion exists in a highly unstable dynamic equilibrium with the beholder's usual reality orientation. If either orientation is too powerful, the dynamic equilibrium is disrupted and the aesthetic experience as such is abolished.

Integrating the philosophy and psychology of aesthetic experience: development of the aesthetic experience scale.

Science.gov (United States)

Stamatopoulou, Despina

2004-10-01

This study assessed the dynamic relationship between person and object in aesthetic experience. Patterns of the structure of aesthetic experience were derived from a conceptual model based on philosophical and psychological ideas. These patterns were further informed by interviewing individuals with extensive involvement in aesthetic activities and 25 secondary students. Accordingly, patterns were tested by developing a large pool of items attempting to identify measurable structural components of aesthetic experience. Refined first in a pilot study, the 36-item questionnaire was administered to 652 Greek students, aged from 13 to 15 years. Correlation matrices and exploratory factor analyses on principal components were used to examine internal structural relationships. The obliquely rotated five-factor solution of the refined instrument accounted for the 44.1% of the total variance and was combatible with the conceptual model of aesthetic experience, indicating the plausibility of both. The internal consistency of the items was adequate and external correlational analysis offered preliminary support for subsequent development of a self-report measure that serves to operationalize the major constructs of aesthetic experience in the general adolescent population. The results also raise theoretical issues for those interested in empirical aesthetics, suggesting that in experiential functioning, expressive perception and affect may play a more constructive role in cognitive processes than is generally acknowledged.

Design and the question of aesthetics

DEFF Research Database (Denmark)

Friberg, Carsten

2014-01-01

In the article an approach to aesthetics is suggested with the focus on the education of the designer rather than on the outcome of the design. Design is taken to be an interpretative intervention into a social context which requires a sensibility for the context. The forming of this sensibility...... in the social context a central issue of aesthetics. Here, is the argument, is the link to an aesthetic education understood as an education of our senses through cultural products which is also a link to a perspective that appears to be absent in present debates on aesthetics in relation to design. Taking up...... is the goal of an aesthetic education. Through discussions of different approaches to aesthetics like Grant Kester’s dialogical aesthetics and Kant’s critique of the faculty of judgement, it is emphasized how sensibility as the key focus of aesthetics rather than art and beauty makes the ability to manoeuvre...

Chromatic graph theory

Chartrand, Gary; Rosen, Kenneth H

2008-01-01

Beginning with the origin of the four color problem in 1852, the field of graph colorings has developed into one of the most popular areas of graph theory. Introducing graph theory with a coloring theme, Chromatic Graph Theory explores connections between major topics in graph theory and graph colorings as well as emerging topics. This self-contained book first presents various fundamentals of graph theory that lie outside of graph colorings, including basic terminology and results, trees and connectivity, Eulerian and Hamiltonian graphs, matchings and factorizations, and graph embeddings. The remainder of the text deals exclusively with graph colorings. It covers vertex colorings and bounds for the chromatic number, vertex colorings of graphs embedded on surfaces, and a variety of restricted vertex colorings. The authors also describe edge colorings, monochromatic and rainbow edge colorings, complete vertex colorings, several distinguishing vertex and edge colorings, and many distance-related vertex coloring...

Long Memory of Pathfinding Aesthetics

Directory of Open Access Journals (Sweden)

Ron Coleman

2009-01-01

Full Text Available This paper investigates a new dynamic (i.e., space-time model to measure aesthetic values in pathfinding for videogames. The results we report are important firstly because the artificial intelligence literature has given relatively little attention to aesthetic considerations in pathfinding. Secondly, those investigators who have studied aesthetics in pathfinding have relied largely on anecdotal arguments rather than metrics. Finally, in those cases where metrics have been used in the past, they show only that aesthetic paths are different. They provide no quantitative means to classify aesthetic outcomes. The model we develop here overcomes these deficiencies using rescaled range (R/S analysis to estimate the Hurst exponent, . It measures long-range dependence (i.e., long memory in stochastic processes and provides a novel well-defined mathematical classification for pathfinding. Indeed, the data indicates that aesthetic and control paths have statistically significantly distinct signatures. Aesthetic paths furthermore have more long memory than controls with an effect size that is large, more than three times that of an alternative approach. These conclusions will be of interest to researchers investigating games as well as other forms of entertainment, simulation, and in general nonshortest path motion planning.

Since the approval of botulinum toxin, dermal fillers, and lasers for cosmetic use, minimally invasive aesthetic procedures have rapidly become the treatments of choice for age-related facial changes.

Botulinum toxin and dermal filler injections, laser hair reduction, chemical peels, laser skin resurfacing, microdermabrasion, and intense pulsed light photorejuvenation were the most commonly performed procedures in 2008. These procedures are effective and associated with minimal discomfort, and they have a low incidence of adverse effects and short recovery times. High patient and physician satisfaction have contributed to their growing popularity and availability in the primary care setting. As patient demand for aesthetic treatments increases, family physicians should be familiar with common minimally invasive aesthetic procedures when advising patients or incorporating aesthetic care into office practice.

Aesthetic activities and aesthetic attitudes: influences of education, background and personality on interest and involvement in the arts.

Science.gov (United States)

McManus, I C; Furnham, A

2006-11-01

There have been few studies of why some people are frequently involved in aesthetic activities such as going to the theatre, reading or playing musical instruments, whereas others are less involved. This study assesses the broad roles of education, personality and demographic factors such as social class, age and sex. More aesthetic activity was associated with music and art education, whereas science education had a substantial negative relationship with aesthetic activity, both directly and also indirectly via reduced art education. More aesthetic activity was particularly related to higher scores on the personality factor of openness, and also to lower scores on agreeableness and conscientiousness. Higher parental social class was also associated with more aesthetic activity, as also was lower age. Sex had no relationship to aesthetic activity, as neither did masculinity-femininity. Positive aesthetic attitudes were also related moderately to aesthetic activity, but were particularly strongly related to openness to experience, and somewhat less to extraversion. Class, age and sex had no direct relationship to aesthetic attitudes.

Studies in Cup Drawing Behavior of Polymer Laminated Sheet Metal

Elnagmi, M.; Jain, M.; Bruhis, M.; Nielsen, K.

2011-08-01

Axisymmetric deep drawing behavior of a polymer laminated sheet metal (PLSM) is investigated using an axisymmetric cup drawing test. PLSMs are of interest as a replacement for painted finishes for automotive applications as they have the potential to achieve good quality long lasting and aesthetically appealing surfaces on stamped parts. However, there is limited understanding of PLSMs in automotive deep drawing situations to produce complex 3-D parts. The tests are carried out using well-controlled, laboratory-based, dual-action, servo-hydraulic forming presses under blank-holder force and punch displacement control conditions. An optical strain mapping system is used to measure the surface strains (and to construct 3D strain maps) from the film side of the deformed samples for a range of forming conditions. Deep drawing characteristics such as punch load versus punch displacement traces, strain distribution along the cup profile, flange wrinkling and fracture characteristics are experimentally assessed for stainless steel-plastic film laminated sheet materials. Also the effect of lamination pressure on wrinkling and delamination is investigated for a decorative pressure sensitive adhesive film affixed to the stainless steel sheet.

Coevolutionary aesthetics in human and biotic artworlds.

Science.gov (United States)

Prum, Richard O

2013-01-01

This work proposes a coevolutionary theory of aesthetics that encompasses both biotic and human arts. Anthropocentric perspectives in aesthetics prevent the recognition of the ontological complexity of the aesthetics of nature, and the aesthetic agency of many non-human organisms. The process of evaluative coevolution is shared by all biotic advertisements. I propose that art consists of a form of communication that coevolves with its own evaluation. Art and art history are population phenomena. I expand Arthur Danto's Artworld concept to any aesthetic population of producers and evaluators. Current concepts of art cannot exclusively circumscribe the human arts from many forms of non-human biotic art. Without assuming an arbitrarily anthropocentric perspective, any concept of art will need to engage with biodiversity, and either recognize many instances of biotic advertisements as art, or exclude some instances of human art. Coevolutionary aesthetic theory provides a heuristic account of aesthetic change in both human and biotic artworlds, including the coevolutionary origin of aesthetic properties and aesthetic value within artworlds. Restructuring aesthetics, art criticism, and art history without human beings at the organizing centers of these disciplines stimulate new progress in our understanding of art, and the unique human contributions to aesthetics and aesthetic diversity.

Wulff-Nilsen, Christian

structural properties that can be exploited.

Specialized algorithms that take advantage of such properties are often orders...... of magnitude faster than the corresponding algorithms for general graphs. The first and main part of this thesis focuses on the development of efficient planar graph algorithms.

Roughly speaking, the stretch factor is a real value expressing how well a (geo-)metric graph approximates the underlying complete graph w.r.t. distances. We give improved algorithms for computing the stretch factor of a given graph and for augmenting...

Troiage Aesthetics

Science.gov (United States)

Brown, Sheldon

As the world around us is transformed into digitally enabled forms and processes, aesthetic strategies are required that articulate this underlying condition. A method for doing so involves a formal and conceptual strategy that is derived from collage, montage and assemblage. This triple "age" is termed "troiage", and it uses a style of computational apparency which articulates the edges of our current representational forms and processes as the semantic elements of culture. Each of these component aesthetics has previously had an important effect upon different areas of contemporary art and culture. Collage in painting, montage in film, assemblage in sculpture and architecture, are recombined via algorithmic methods, forefronting the structure of the algorithmic itself. The dynamic of the aesthetic is put into play by examining binary relationships such as: nature/culture, personal/public, U.S/Mexico, freedom/coercion, mediation/experience, etc. Through this process, the pervasiveness of common algorithmic approaches across cultural and social operations is revealed. This aesthetic is used in the project "The Scalable City" in which a virtual urban landscape is created by users interacting with data taken from the physical world in the form of different photographic techniques. This data is transformed by algorithmic methods which have previously been unfamiliar to the types of data that they are utilizing. The Scalable City project creates works across many media; such as prints, procedural animations, digital cinema and interactive 3D computer graphic installations.

Aesthetic occiput augmentation using methylmethacrylate.

Science.gov (United States)

Song, Yong Tai

2015-01-01

Cranioplasty for only aesthetic reasons has not been commonly performed to date. However, recently there has been a new focus by the public on a more aesthetically pleasing head shape with frequent patient requests for purely aesthetic contouring of the occiput, an important definer of cosmetic head shape. For example, in Asia, where the normal cranial shape is mesocephalic or brachycephalic and often with a planar occiput, requests for its aesthetic correction are increasingly common. Accordingly, the author developed a minimally invasive occiput augmentation using methylmethacrylate. In this study, the indications for aesthetic occiput contouring were planar occiput, left-right asymmetric occiput, and grooved occiput. Under local anesthesia, soft methylmethacrylate is subperiosteally inserted through a small incision (about 5-cm length), manually and precisely contoured in situ through the scalp to the desired occipital shape. All is performed as an outpatient procedure, and a quick recovery is the case. Between March 2007 and October 2013, 959 patients received such aesthetic occiput augmentation. The mean follow-up period was 49 months (range, 3-84 months). Nearly all patients were satisfied with the outcome, and complications were very rare. Only 5 patients (0.5%) needed additional corrective procedures. The author has concluded that aesthetic occiput augmentation using methylmethacrylate yields consistent, predictable, and satisfactory results. Additional long-term follow-up is required for a final conclusion, however.

The Aesthetics Of Trademarks

Directory of Open Access Journals (Sweden)

Peter H. Karlen

2008-01-01

Full Text Available Trademarks are not just property, they are aesthetic creations that pervade everyday experience. One estimate is that the average person encounters more than 1,000 trademarks per day, many of which influence purchases and product use. As pervasive aesthetic creations having literary, pictorial, graphic, sculptural, and musical content, trademarks deserve aesthetic analysis. The article discusses the origins, strength, appeal, and effectiveness of trademarks within the context of aesthetic considerations such as meaning, intention, authorship, and mode of creation. Also reviewed are morphemic and phonemic analysis of trademarks, semantic positioning, the dichotomy between creation and discovery of trademarks, and the differences between trademarks and titles. The discussion is confined to "word marks" consisting of alphanumeric characters, since discussing other kinds of marks (such as designs, configurations, sounds, colors, and scents would raise issues well beyond the scope of a single article.

Using Behavior Over Time Graphs to Spur Systems Thinking Among Public Health Practitioners.

Science.gov (United States)

Calancie, Larissa; Anderson, Seri; Branscomb, Jane; Apostolico, Alexsandra A; Lich, Kristen Hassmiller

2018-02-01

Public health practitioners can use Behavior Over Time (BOT) graphs to spur discussion and systems thinking around complex challenges. Multiple large systems, such as health care, the economy, and education, affect chronic disease rates in the United States. System thinking tools can build public health practitioners' capacity to understand these systems and collaborate within and across sectors to improve population health. BOT graphs show a variable, or variables (y axis) over time (x axis). Although analyzing trends is not new to public health, drawing BOT graphs, annotating the events and systemic forces that are likely to influence the depicted trends, and then discussing the graphs in a diverse group provides an opportunity for public health practitioners to hear each other's perspectives and creates a more holistic understanding of the key factors that contribute to a trend. We describe how BOT graphs are used in public health, how they can be used to generate group discussion, and how this process can advance systems-level thinking. Then we describe how BOT graphs were used with groups of maternal and child health (MCH) practitioners and partners (N = 101) during a training session to advance their thinking about MCH challenges. Eighty-six percent of the 84 participants who completed an evaluation agreed or strongly agreed that they would use this BOT graph process to engage stakeholders in their home states and jurisdictions. The BOT graph process we describe can be applied to a variety of public health issues and used by practitioners, stakeholders, and researchers.

The psychology of Kant's aesthetics.

Science.gov (United States)

Guyer, Paul

2008-12-01

Contrary to both his own intentions and the views of both older and more recent commentators. I argue that Kant's aesthetics remains within the confines of eighteenth-century aesthetics as a branch of empirical psychology, as it was then practiced. Kant established a plausible connection between aesthetic experience and judgment on the one hand and cognition in general on the other, through his explanatory concept of the free play of our cognitive powers. However, there is nothing distinctly 'a priori' or 'transcendental' in his claim that this state of mind is what causes our pleasure in beauty or other aesthetic properties. Nor did Kant establish a genuinely a priori or transcendental principle that all human beings have the same disposition to experience a free play of their cognitive powers, let alone in response to the same objects. This failure, however, in no way limits the continuing significance of Kant's aesthetic theory.

Degree Associated Edge Reconstruction Number of Graphs with Regular Pruned Graph

Full Text Available An ecard of a graph $G$ is a subgraph formed by deleting an edge. A da-ecard specifies the degree of the deleted edge along with the ecard. The degree associated edge reconstruction number of a graph $G,~dern(G,$ is the minimum number of da-ecards that uniquely determines $G.$  The adversary degree associated edge reconstruction number of a graph $G, adern(G,$ is the minimum number $k$ such that every collection of $k$ da-ecards of $G$ uniquely determines $G.$ The maximal subgraph without end vertices of a graph $G$ which is not a tree is the pruned graph of $G.$ It is shown that $dern$ of complete multipartite graphs and some connected graphs with regular pruned graph is $1$ or $2.$ We also determine $dern$ and $adern$ of corona product of standard graphs.

Aesthetic Diagnosis in Gestalt Therapy.

Science.gov (United States)

Roubal, Jan; Francesetti, Gianni; Gecele, Michela

2017-10-17

The diagnostic process in psychotherapy using the aesthetic evaluation is described in this article. Unlike the classical diagnostic process, which presents a result of comparing clinicians´ observations with a diagnostic system (DSM, ICD, etc.), the aesthetic evaluation is a pre-reflexive, embodied, and preverbal process. A Gestalt Therapy theoretical frame is used to introduce a concept of the aesthetic diagnostic process. During this process, the clinicians use their own here-and-now presence, which takes part in the co-creation of the shared relational field during the therapeutic session. A specific procedure of the aesthetic evaluation is introduced. The clinical work with depressed clients is presented to illustrate this perspective.

Graph Theory. 2. Vertex Descriptors and Graph Coloring

Directory of Open Access Journals (Sweden)

Lorentz JÄNTSCHI

2002-12-01

Full Text Available This original work presents the construction of a set of ten sequence matrices and their applications for ordering vertices in graphs. For every sequence matrix three ordering criteria are applied: lexicographic ordering, based on strings of numbers, corresponding to every vertex, extracted as rows from sequence matrices; ordering by the sum of path lengths from a given vertex; and ordering by the sum of paths, starting from a given vertex. We also examine a graph that has different orderings for the above criteria. We then proceed to demonstrate that every criterion induced its own partition of graph vertex. We propose the following theoretical result: both LAVS and LVDS criteria generate identical partitioning of vertices in any graph. Finally, a coloring of graph vertices according to introduced ordering criteria was proposed.

On an edge partition and root graphs of some classes of line graphs

Directory of Open Access Journals (Sweden)

K Pravas

2017-04-01

Full Text Available The Gallai and the anti-Gallai graphs of a graph $G$ are complementary pairs of spanning subgraphs of the line graph of $G$. In this paper we find some structural relations between these graph classes by finding a partition of the edge set of the line graph of a graph $G$ into the edge sets of the Gallai and anti-Gallai graphs of $G$. Based on this, an optimal algorithm to find the root graph of a line graph is obtained. Moreover, root graphs of diameter-maximal, distance-hereditary, Ptolemaic and chordal graphs are also discussed.

Graphs and matrices

Bapat, Ravindra B

2014-01-01

This new edition illustrates the power of linear algebra in the study of graphs. The emphasis on matrix techniques is greater than in other texts on algebraic graph theory. Important matrices associated with graphs (for example, incidence, adjacency and Laplacian matrices) are treated in detail. Presenting a useful overview of selected topics in algebraic graph theory, early chapters of the text focus on regular graphs, algebraic connectivity, the distance matrix of a tree, and its generalized version for arbitrary graphs, known as the resistance matrix. Coverage of later topics include Laplacian eigenvalues of threshold graphs, the positive definite completion problem and matrix games based on a graph. Such an extensive coverage of the subject area provides a welcome prompt for further exploration. The inclusion of exercises enables practical learning throughout the book. In the new edition, a new chapter is added on the line graph of a tree, while some results in Chapter 6 on Perron-Frobenius theory are reo...

Aesthetic Engagement, Ecosophy C, and Ecological Appreciation

Directory of Open Access Journals (Sweden)

Cheng Xiangzhan

2013-01-01

Full Text Available With the aim of healing the earth and sustain a healthy ecosystem for all life forms, not humankind alone, ecoaesthetics emerges as a critique of Enlightenment mentality and of modern aesthetics as it is embodied in it. This mentality contributes greatly to the global ecological crisis and to other problem areas, such as population, economic, political and religious ones. In my understanding of aesthetics, ecoaesthetics is defined as the theory of ecological aesthetic appreciation.[1] With ecoaesthetics as my research horizon, there are at least two reasons for me to pay special attention to American philosopher Arnold Berleant’s conception of aesthetic engagement and his aesthetic theory based on it, an aesthetics of engagement. The first is our shared theme, which is the critique of modern aesthetics. The second reason is more complex for it involves the crucial question of the proper manner of aesthetic appreciation. From the perspective of ecoaesthetics, the contemplation of objects by a separated perceiver, an approach that is based on the modern philosophical dualism of subject and object, is unsatisfactory and inadequate. Berleant’s aesthetic engagement is a more satisfactory account of appreciation that is aesthetic and ecological. This emphasizes the ecological continuity or interrelatedness between the human appreciator and objects. Of course, any theory can occasion critique and development. Based on Berleant’s idea of aesthetic engagement, I would like to propose Ecosophy C. This can be contrasted with Ecosophy T proposed by the Norwegian, Arne Naess, and with traditional Chinese aesthetic wisdom. In contrast with these, I would like to develop my own view of ecological understanding. In order to construct a more comprehensive and reasonable ecoaesthetics, my Ecosophy C contains eight points that are crucial in building an ecological model of aesthetic appreciation for this period of ecological crisis.

Graphs cospectral with a friendship graph or its complement

2013-12-01

Full Text Available Let $n$ be any positive integer and let $F_n$ be the friendship (or Dutch windmill graph with $2n+1$ vertices and $3n$ edges. Here we study graphs with the same adjacency spectrum as the $F_n$. Two graphs are called cospectral if the eigenvalues multiset of their adjacency matrices are the same. Let $G$ be a graph cospectral with $F_n$. Here we prove that if $G$ has no cycle of length $4$ or $5$, then $Gcong F_n$. Moreover if $G$ is connected and planar then $Gcong F_n$.All but one of connected components of $G$ are isomorphic to $K_2$.The complement $overline{F_n}$ of the friendship graph is determined by its adjacency eigenvalues, that is, if $overline{F_n}$ is cospectral with a graph $H$, then $Hcong overline{F_n}$.

2014-12-01

Full Text Available In this article, the authors perform an analysis in order to assess adaptation of magnetic force-directed algorithms for context-based information extraction from multi-attributed graphs during visualization sessions. Theoretic standings behind magnetic force-directed approach are stated together with review on how particular features of respective algorithms in combination with appropriate visual techniques are especially suitable for improved processing and presenting of knowledge that is captured in form of graphs. The complexity of retrieving multi-attributed information within the proposed approach is handled with dedicated tools, such as selective attraction of nodes to MFE (Magnetic Force Emitter based on search criteria, localization of POI (Point of Interest regions, graph node anchoring, etc. Implicit compatibility of aforementioned tools with interactive nature of data exploration is distinguished. Description of case study, based on bibliometric network analysis is given, which is followed by the review of existing related works in this field. Conclusions are made and further studies in the field of visualization of multi-attributed graphs are defined.

Aura, Self, and Aesthetic Experience

Full Text Available Aesthetic experiences are generated in encounters with cultural objects and such experiences are marked by the free play of cognitive and numinous experience unstructured by concepts. Kant’s famous three types of pleasure, made infamous in social theory by Pierre Bourdieu, are examined in relation to the critical theoretical concept of aura, the social psychology of “flow,” and cognitive explanations of perception to explain experience in aesthetic fields. Theories of aesthetic experience developed at the crossroad of critical social thought and cognitive science hold promise for a social analysis able to avoid the usual sociological pitfalls of either ignoring aesthetics or reducing it to structurally determined differences of taste.

Graph embedding with rich information through heterogeneous graph

KAUST Repository

Sun, Guolei

2017-11-12

Graph embedding, aiming to learn low-dimensional representations for nodes in graphs, has attracted increasing attention due to its critical application including node classification, link prediction and clustering in social network analysis. Most existing algorithms for graph embedding only rely on the topology information and fail to use the copious information in nodes as well as edges. As a result, their performance for many tasks may not be satisfactory. In this thesis, we proposed a novel and general framework for graph embedding with rich text information (GERI) through constructing a heterogeneous network, in which we integrate node and edge content information with graph topology. Specially, we designed a novel biased random walk to explore the constructed heterogeneous network with the notion of flexible neighborhood. Our sampling strategy can compromise between BFS and DFS local search on heterogeneous graph. To further improve our algorithm, we proposed semi-supervised GERI (SGERI), which learns graph embedding in an discriminative manner through heterogeneous network with label information. The efficacy of our method is demonstrated by extensive comparison experiments with 9 baselines over multi-label and multi-class classification on various datasets including Citeseer, Cora, DBLP and Wiki. It shows that GERI improves the Micro-F1 and Macro-F1 of node classification up to 10%, and SGERI improves GERI by 5% in Wiki.

Naturalizing aesthetics: brain areas for aesthetic appraisal across sensory modalities.

Science.gov (United States)

Brown, Steven; Gao, Xiaoqing; Tisdelle, Loren; Eickhoff, Simon B; Liotti, Mario

2011-09-01

We present here the most comprehensive analysis to date of neuroaesthetic processing by reporting the results of voxel-based meta-analyses of 93 neuroimaging studies of positive-valence aesthetic appraisal across four sensory modalities. The results demonstrate that the most concordant area of activation across all four modalities is the right anterior insula, an area typically associated with visceral perception, especially of negative valence (disgust, pain, etc.). We argue that aesthetic processing is, at its core, the appraisal of the valence of perceived objects. This appraisal is in no way limited to artworks but is instead applicable to all types of perceived objects. Therefore, one way to naturalize aesthetics is to argue that such a system evolved first for the appraisal of objects of survival advantage, such as food sources, and was later co-opted in humans for the experience of artworks for the satisfaction of social needs.

A linear graph for digoxin radioimmunoassay

International Nuclear Information System (INIS)

Smith, S.E.; Richter, A.

1975-01-01

The determination of drug or hormone concentrations by radio-immunoassay involves interpolation of values for radioisotope counts within standard curves, a technique which requires some dexterity in curve drawing and which results in some inaccuracy in practice. Most of the procedures designed to overcome these difficulties are complex and time-consuming. In radioimmunoassays involving saturation of the antibody-binding sites a special case exists in that the bound radioactivity is directly proportional to the specific activity of the ligand in the system. Thus a graph of the ratio of radioactivity bound in the absence to that in the presence of added non-radioactive ligand is linear against the concentration of added ligand (Hales,C.N., and Randle, P.J., 1963, Biochem. J., vol. 88, 137). A description is given of a simple and convenient modification of their method, and its application to the routine clinical determination of digoxin using a commercial kit (Lanoxitest β digoxin radioimmunoassay kit, Wellcome Reagents Ltd.). Specially constructed graph paper, which yields linearity with standard solutions, was designed so that it could be used directly without data transmission. The specific activity function appears as the upper arithmetical horizontal scale; corresponding values of the concentration of non-radioactive ligand in the solution added were individually calculated and appear on the lower scale opposite the appropriate values of the upper scale. The linearity of the graphs obtained confirmed that binding of digoxin was approximately constant through the range of clinical concentrations tested (0.5 to 8ng/ml), although binding declined slightly at higher concentrations.

Computational and Experimental Approaches to Visual Aesthetics

Brachmann, Anselm; Redies, Christoph

2017-01-01

Aesthetics has been the subject of long-standing debates by philosophers and psychologists alike. In psychology, it is generally agreed that aesthetic experience results from an interaction between perception, cognition, and emotion. By experimental means, this triad has been studied in the field of experimental aesthetics, which aims to gain a better understanding of how aesthetic experience relates to fundamental principles of human visual perception and brain processes. Recently, researchers in computer vision have also gained interest in the topic, giving rise to the field of computational aesthetics. With computing hardware and methodology developing at a high pace, the modeling of perceptually relevant aspect of aesthetic stimuli has a huge potential. In this review, we present an overview of recent developments in computational aesthetics and how they relate to experimental studies. In the first part, we cover topics such as the prediction of ratings, style and artist identification as well as computational methods in art history, such as the detection of influences among artists or forgeries. We also describe currently used computational algorithms, such as classifiers and deep neural networks. In the second part, we summarize results from the field of experimental aesthetics and cover several isolated image properties that are believed to have a effect on the aesthetic appeal of visual stimuli. Their relation to each other and to findings from computational aesthetics are discussed. Moreover, we compare the strategies in the two fields of research and suggest that both fields would greatly profit from a joined research effort. We hope to encourage researchers from both disciplines to work more closely together in order to understand visual aesthetics from an integrated point of view. PMID:29184491

To assess the prevalence of body dysmorphic disorder (BDD) in an aesthetic surgery setting in the region of Southwest China, and to ascertain the differences in terms of body images between patients in the aesthetic setting and general Chinese population. This study tracked patient satisfaction with their body image changes while undergoing aesthetic medical procedures to identify whether the condition of patients who were presenting with BDD symptoms or their psychological symptoms could be improved by enhancing their appearance. Additionally, this study explored whether there was improvement in quality of life (QoL) and self-esteem after aesthetic medical procedures. A total of 106 female patients who were undergoing aesthetic medical procedures for the first time (plastic surgery, n = 26; minimally invasive aesthetic treatment, n = 42; and aesthetic dermatological treatment, n = 38) were classified as having body dysmorphic disorder symptoms or not having body dysmorphic disorder symptoms, based on the body dysmorphic disorder examination (BDDE), which was administered preoperatively. These patients were followed up for 1 month after the aesthetic procedures. The multidimensional body self-relations questionnaire-appearance scales (MBSRQ-AS) and rosenberg self-esteem scale (RSE-S) were used to assess patients' preoccupation with appearance and self-esteem pre-procedure and 1 month post-procedure. Additionally, 100 female healthy control participants were recruited as a comparative group into this study and they were also assessed using BDDE, MBSRQ-AS, and RSE-S. A total of 14.2 % of 106 aesthetic patients and 1 % of 100 healthy controls were diagnosed with BDD to varying extents. BDDE scores were 72.83 (SD ± 30.7) and 68.18 (SD ± 31.82), respectively, before and after the procedure for the aesthetic patient group and 43.44 (SD ± 15.65) for the healthy control group (F = 34.28; p aesthetic patients (pre-procedure) and female adult norms from

2005-01-01

Full Text Available Although discourses of immersive aesthetics and distributed aesthetics may evoke associations with different media, creative processes, modes of audience engagement and even political ideologies, artists using these aesthetics often share similar interests in transforming and enhancing notions of the body and perception through technological intervention. This paper undertakes a comparison between immersive and distributed aesthetics in relation to Virtual Reality (VR and Networked Art (net.art, particularly networked installation art. It focuses on the ways in which both VR and networked installations immerse the viewer in states of perceptual and cognitive transition. Central to this article is the argument that VR and net.art are able to generate immersive experiences in the viewer by creating the sensation of being (tele-present in an electronically mediated environment that is illusionistic and sometimes remote from the physical body of the participant. Furthermore, the immersive and distributed aesthetics generated by specific VR and net.art projects have revolutionary consequences for traditional aesthetic theories of spectatorship and art appreciation that assert the need for critical and physical distance.

Full Text Available The energy of a molecular graph G is defined as the summation of the absolute values of the eigenvalues of adjacency matrix of a graph G. In this paper, an infinite class of fullerene graphs with 10n vertices, n ≥ 2, is considered. By proving centrosymmetricity of the adjacency matrix of these fullerene graphs, a lower bound for its energy is given. Our method is general and can be extended to other class of fullerene graphs.

Numerical integration methods and layout improvements in the context of dynamic RNA visualization.

Science.gov (United States)

Shabash, Boris; Wiese, Kay C

2017-05-30

RNA visualization software tools have traditionally presented a static visualization of RNA molecules with limited ability for users to interact with the resulting image once it is complete. Only a few tools allowed for dynamic structures. One such tool is jViz.RNA. Currently, jViz.RNA employs a unique method for the creation of the RNA molecule layout by mapping the RNA nucleotides into vertexes in a graph, which we call the detailed graph, and then utilizes a Newtonian mechanics inspired system of forces to calculate a layout for the RNA molecule. The work presented here focuses on improvements to jViz.RNA that allow the drawing of RNA secondary structures according to common drawing conventions, as well as dramatic run-time performance improvements. This is done first by presenting an alternative method for mapping the RNA molecule into a graph, which we call the compressed graph, and then employing advanced numerical integration methods for the compressed graph representation. Comparing the compressed graph and detailed graph implementations, we find that the compressed graph produces results more consistent with RNA drawing conventions. However, we also find that employing the compressed graph method requires a more sophisticated initial layout to produce visualizations that would require minimal user interference. Comparing the two numerical integration methods demonstrates the higher stability of the Backward Euler method, and its resulting ability to handle much larger time steps, a high priority feature for any software which entails user interaction. The work in this manuscript presents the preferred use of compressed graphs to detailed ones, as well as the advantages of employing the Backward Euler method over the Forward Euler method. These improvements produce more stable as well as visually aesthetic representations of the RNA secondary structures. The results presented demonstrate that both the compressed graph representation, as well as the Backward

To assess the psychosocial impact of dental aesthetics using the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ) and self-rated Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Cross-sectional study. Dental Section, the Aga Khan University Hospital, Karachi, from August to September 2006. Adults with no prior orthodontic treatment were asked to complete a modified version of the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ). A total of four variables including 'Dental Self-confidence', 'Social impact', 'Psychological impact' and 'Perceived orthodontic treatment need' were assessed by a series of statements, whereas dental aesthetics were assessed by the respondents using the IOTN Aesthetic Component (self-rated IOTN-AC). Kruskal-Walli's test was applied to determine significance. The respondents were 120 adults (70 females and 50 males; mean age 25.8 years), all four of the above-mentioned variables measuring psychosocial impact showed positive and significant correlations with the perceived severity of malocclusion as depicted by the Aesthetic Component (AC) of Index of Orthodontic Treatment Need (IOTN), with p-value of less than 0.01 for all variables. The results indicate the strong psychosocial impact of altered dental aesthetics on the emotional state of an individual. The association between self-rated IOTN-AC grading with psychosocial well-being stands established, indicating that the perceived aesthetics of malocclusion may be as significant a factor in determining treatment need as the degree of malocclusion.

[A "dialogue" between the aesthetics of nursing and philosophy].

Science.gov (United States)

Chang, Chia-Hsiu; Chen, Chung-Hey

2012-02-01

Nursing aesthetics belong to the broader school of aesthetics, a branch of philosophy, as well as the nursing arts, an element of professional nursing. The philosophy of aesthetics recognizes the connection between an author and appreciators and identifies both substantive and abstract aesthetic experiences in interpersonal communication through the fine arts. Nursing aesthetics values the meaningful moments of patients, is sensitive to the influences of different circumstances and situations, and appreciates the unique qualities of humanness. Nursing aesthetics is emancipatory knowledge and involves empirical, ethical and personal knowing. The article is based on a search of OvidSP and Chinese Electronic Periodical Services (CEPS) database references using key words including aesthetic, aesthetics, art of nursing, or nursing aesthetics as well as a review of books related to aesthetics, knowledge construction, and nursing aesthetics. Authors determined definitions as defined by nursing experts and the applications thereof in clinical practice. This article aimed to illustrate that the ultimate concern of philosophy is "goodness" and that the foundation of caring behaviors is "love". In practice, nursing aesthetics is expressed through empathy, appreciation, inspiration and the therapeutic use of the self. Through aesthetic knowing and enhanced perceptual sensibility and reflection, nurses can transform intuitive knowing into art-acts and ultimately enhance nursing care quality.

Social Ecology and Aesthetic Criticism

Owen, Connor

2016-12-01

Full Text Available While ecocriticism has become a respected field in literary theory and in the broader landscape of aesthetic philosophy, it could benefit from an enhanced ethical-political framework which social ecology – an underrated critical theory developed by Murray Bookchin – could provide. This essay attempts to tease out the potentials for such a framework, integrating the insights of social ecology, ecocriticism, Critical Realism, and John Dewey's aesthetic concepts into a layered idea-set used for the study of all kinds of aesthetic objects, from popular art to the gallery arts. Its key principles are the emergence of aesthetic objects (including formal artworks out of congealed human experience, the relation between organism and environment in assessing meaning, the breakdown of implicit or overt hierarchies within a work, and the idea of the artist and art-critic as a "gardener".

Orthodontics in the "Art" of Aesthetics.

Science.gov (United States)

Thomas, Mayuri

2015-01-01

Aesthetics in dentistry has of late become an awakening/actor among patients and often serves as a major reason for seeking dental treatment and care. Ever since the introduction of orthodontics as a separate specialty branch in dentistry, a variety of techniques have evolved, and methods developed both in the type of devices/instruments used and treatments planned. The discipline of orthodontic aesthetics involves micro and macro aesthetics, gingival, and facial aesthetics. This article helps focus on the artistic part of the orthodontic science. It brings out various important factors involved in customizing aesthetic orthodontic treatment planning according to the individual needs of the patient. Through this kind of treatment planning not only are the functional and biological needs of the patient met, they also provide a stable and durable results. Less invasive treatment planning makes it easier for the patient to select future treatment options as new technologies keep evolving. The review was selected by typing aesthetic orthodontics in the Google search engine, Pubmed, and Pubmed Central. Literature review of articles reflecting history, different analysis, factors responsible, and the latest technique was conducted.

Non-heuristic reduction of the graph in graph-cut optimization

International Nuclear Information System (INIS)

Malgouyres, François; Lermé, Nicolas

2012-01-01

During the last ten years, graph cuts had a growing impact in shape optimization. In particular, they are commonly used in applications of shape optimization such as image processing, computer vision and computer graphics. Their success is due to their ability to efficiently solve (apparently) difficult shape optimization problems which typically involve the perimeter of the shape. Nevertheless, solving problems with a large number of variables remains computationally expensive and requires a high memory usage since underlying graphs sometimes involve billion of nodes and even more edges. Several strategies have been proposed in the literature to improve graph-cuts in this regards. In this paper, we give a formal statement which expresses that a simple and local test performed on every node before its construction permits to avoid the construction of useless nodes for the graphs typically encountered in image processing and vision. A useless node is such that the value of the maximum flow in the graph does not change when removing the node from the graph. Such a test therefore permits to limit the construction of the graph to a band of useful nodes surrounding the final cut.

Towards a Wittgensteinian Aesthetics. Wollheim and the Analysis of Aesthetic Practices

Giovanni Matteucci

2013-05-01

Full Text Available In order to investigate the possibility to develop Wittgenstein's suggestions about aesthetics, this paper will focus on the organic perspective elaborated by Richard Wollheim in «Art and Its Objects». In this regard we will try to emphasize how the concept of art as a "form of live" - explicit in Wollheim - involves the analysis of the practices embodied in the experience of art starting from those of representation. The inception modes of such practices of representation need to be described in the use of specific anthropological abilities related to perception patterns that go beyond the mere statement of facts, in a fusion among aesthetic, cognitive and emotional levels. Deepening the relationships both between lived experience and expression, and expression and understanding, we will try to point out how Wollheim (and Wittgenstein places any rhetoric of the ineffable out of the game, even regarding the analysis of the aesthetic experience.

Graphing trillions of triangles.

Science.gov (United States)

Burkhardt, Paul

2017-07-01

The increasing size of Big Data is often heralded but how data are transformed and represented is also profoundly important to knowledge discovery, and this is exemplified in Big Graph analytics. Much attention has been placed on the scale of the input graph but the product of a graph algorithm can be many times larger than the input. This is true for many graph problems, such as listing all triangles in a graph. Enabling scalable graph exploration for Big Graphs requires new approaches to algorithms, architectures, and visual analytics. A brief tutorial is given to aid the argument for thoughtful representation of data in the context of graph analysis. Then a new algebraic method to reduce the arithmetic operations in counting and listing triangles in graphs is introduced. Additionally, a scalable triangle listing algorithm in the MapReduce model will be presented followed by a description of the experiments with that algorithm that led to the current largest and fastest triangle listing benchmarks to date. Finally, a method for identifying triangles in new visual graph exploration technologies is proposed.

Birkhoff’s aesthetic measure

Directory of Open Access Journals (Sweden)

Veronika Douchová

2016-08-01

Full Text Available In this paper, we review and critically evaluate George D. Birkhoff’s work concerning formalisation of aesthetics, as it appeared in his book Aaesthetic Measure from 1933, and discuss its influence on further research in the field. In the book, Birkhoff defines an aesthetic measure M of an art object as the ratio between its order and complexity, or more generally a function f of this ratio: M = f (OC , where O stands for order and C for complexity. The specific definitions of O and C depend on the type of the analysed object. Birkhoff applied the formula to multiple classes of objects (e.g. vases, music, or English poetry and calculated the aesthetic measure for many art objects from these classes. We give an example of Birkhoff’s analysis using polygons, and we further discuss to what extent the ordering of the polygons (or other objects according to the resulting measures can be used, or interpreted, as an ordering according to a degree of aesthetic preference. We also include an extensive bibliography, supplemented by a critical discussion of the influence of Birkhoff’s work on further research.

2017-01-01

Full Text Available Graphing function is an important issue in mathematics education due to its use in various areas of mathematics and its potential roles for students to enhance learning mathematics. The use of some graphing software assists students’ learning during graphing functions. However, the display of graphs of functions that students sketched by hand may be relatively different when compared to the correct forms sketched using graphing software. The possible misleading effects of this situation brought a discussion of a misconception (asymptote misconception on graphing functions. The purpose of this study is two- fold. First of all, this study investigated whether using graphing software (GeoGebra in this case helps students to determine and resolve this misconception in calculus classrooms. Second, the reasons for this misconception are sought. The multiple case study was utilized in this study. University students in two calculus classrooms who received instructions with (35 students or without GeoGebra assisted instructions (32 students were compared according to whether they fell into this misconception on graphing basic functions (1/x, lnx, ex. In addition, students were interviewed to reveal the reasons behind this misconception. Data were analyzed by means of descriptive and content analysis methods. The findings indicated that those who received GeoGebra assisted instruction were better in resolving it. In addition, the reasons behind this misconception were found to be teacher-based, exam-based and some other factors.

High Dimensional Spectral Graph Theory and Non-backtracking Random Walks on Graphs

Science.gov (United States)

Kempton, Mark

This thesis has two primary areas of focus. First we study connection graphs, which are weighted graphs in which each edge is associated with a d-dimensional rotation matrix for some fixed dimension d, in addition to a scalar weight. Second, we study non-backtracking random walks on graphs, which are random walks with the additional constraint that they cannot return to the immediately previous state at any given step. Our work in connection graphs is centered on the notion of consistency, that is, the product of rotations moving from one vertex to another is independent of the path taken, and a generalization called epsilon-consistency. We present higher dimensional versions of the combinatorial Laplacian matrix and normalized Laplacian matrix from spectral graph theory, and give results characterizing the consistency of a connection graph in terms of the spectra of these matrices. We generalize several tools from classical spectral graph theory, such as PageRank and effective resistance, to apply to connection graphs. We use these tools to give algorithms for sparsification, clustering, and noise reduction on connection graphs. In non-backtracking random walks, we address the question raised by Alon et. al. concerning how the mixing rate of a non-backtracking random walk to its stationary distribution compares to the mixing rate for an ordinary random walk. Alon et. al. address this question for regular graphs. We take a different approach, and use a generalization of Ihara's Theorem to give a new proof of Alon's result for regular graphs, and to extend the result to biregular graphs. Finally, we give a non-backtracking version of Polya's Random Walk Theorem for 2-dimensional grids.

Aesthetic Diagnosis in Gestalt Therapy †

Roubal, Jan; Francesetti, Gianni; Gecele, Michela

2017-01-01

The diagnostic process in psychotherapy using the aesthetic evaluation is described in this article. Unlike the classical diagnostic process, which presents a result of comparing clinicians´ observations with a diagnostic system (DSM, ICD, etc.), the aesthetic evaluation is a pre-reflexive, embodied, and preverbal process. A Gestalt Therapy theoretical frame is used to introduce a concept of the aesthetic diagnostic process. During this process, the clinicians use their own here-and-now presence, which takes part in the co-creation of the shared relational field during the therapeutic session. A specific procedure of the aesthetic evaluation is introduced. The clinical work with depressed clients is presented to illustrate this perspective. PMID:29039752

Organization aesthetics in nursing homes.

Science.gov (United States)

Hujala, Anneli; Rissanen, Sari

2011-05-01

The aim of this study was to make visible the material dimensions of nursing management.   Management theories have mainly ignored the material dimensions, namely the physical spaces in which management actually takes place as well as the physical bodies of organization members. The perspective of organization aesthetics enhances our understanding of the role of materiality in nursing management. The data were collected in 2009 using observation and interviews in eight nursing homes. Qualitative content analysis with critical interpretations was used. Three main issues of organizational aesthetics related to nursing management were identified: (1) the functionality of working spaces and equipment; (2) the relevance of 'organizational' space; and (3) the emotional-aesthetic dimension of daily work. Materiality is closely related to management topics, such as decision-making, values and identity formation of organizational members. Aesthetic dimensions of care are constructed by management practices which, in their turn, influence the nature of management. Implications for nursing management  Nurse managers need to be aware of the unintended and unnoticed consequences of materiality and aesthetics. Space and body issues may have considerable effects, for example, on the identity of care workers and on the attractiveness of the care branch. © 2011 The Authors.

Similarity Measure of Graphs

Directory of Open Access Journals (Sweden)

Amine Labriji

2017-07-01

Full Text Available The topic of identifying the similarity of graphs was considered as highly recommended research field in the Web semantic, artificial intelligence, the shape recognition and information research. One of the fundamental problems of graph databases is finding similar graphs to a graph query. Existing approaches dealing with this problem are usually based on the nodes and arcs of the two graphs, regardless of parental semantic links. For instance, a common connection is not identified as being part of the similarity of two graphs in cases like two graphs without common concepts, the measure of similarity based on the union of two graphs, or the one based on the notion of maximum common sub-graph (SCM, or the distance of edition of graphs. This leads to an inadequate situation in the context of information research. To overcome this problem, we suggest a new measure of similarity between graphs, based on the similarity measure of Wu and Palmer. We have shown that this new measure satisfies the properties of a measure of similarities and we applied this new measure on examples. The results show that our measure provides a run time with a gain of time compared to existing approaches. In addition, we compared the relevance of the similarity values obtained, it appears that this new graphs measure is advantageous and  offers a contribution to solving the problem mentioned above.

Art fighting its way back to aesthetics

DEFF Research Database (Denmark)

Sejten, Anne Elisabeth

2016-01-01

. In this essay, ‘Aesthetics is not what you think it is’ is thus an invitation to break through at the very point in which contemporary art seems to state the opposite—that art no longer should be a concern of aesthetics. The iconic example of Marcel Duchamp’s readymade, Fountain, which writes art history......When Claire Farago and Donald Preziosi claim that ‘art is not what you think it is,’ aesthetics itself is implicitly challenged, especially aesthetics’ seemingly inherent correlation with art. However, aesthetics, as complex and ambiguous as the concept of art, calls for a similar suspicion...... at the threshold of contemporary art, is summoned, on the contrary, to give evidence of an intact, though profoundly transformed, aesthetic engagement by the artist....

2016-09-01

Full Text Available Purpose: It has been known that psychological factors have an important effect on the decision to undergo aesthetic surgery. In this study, we aimed to test the hypothesis that the personality traits of people admitted for aesthetic surgery differ from those of people who have never planned to undergo aesthetic surgery in their lives. Material and Methods: Forty-seven patients who were referred to the outpatient clinic of the Faculty of Medicine, Department of Plastic, Reconstructive, and Aesthetic Surgery, Kirikkale University to undergo aesthetic surgery were enrolled in the study. Forty-three subjects who neither underwent nor planned to undergo aesthetic surgery at any time in their lives were included in the study as a control group. Psychometric evaluation of the patients and the control group was conducted using the Turkish version of the Minnesota Multiphasic Personality Inventory (MMPI. Results: Taking 65 as a cut-off point, the ratio of patients who scored and #8805;65 on the hysteria subscale of the MMPI was found to be significantly higher in the sugery group than in the control group and the ratio on social introversion subscale was also higher in the patient group than in the control group, very closely approaching significance. Conclusion: It should be kept in mind that people who have personality traits that can be partially improved with psyachiatric treatment, such as social introverted, lonely, timid, shy, and hysterical and feel the need for validation by others, may be more often admitted for aesthetic surgery.

Pattern graph rewrite systems

Directory of Open Access Journals (Sweden)

Aleks Kissinger

2014-03-01

Full Text Available String diagrams are a powerful tool for reasoning about physical processes, logic circuits, tensor networks, and many other compositional structures. Dixon, Duncan and Kissinger introduced string graphs, which are a combinatoric representations of string diagrams, amenable to automated reasoning about diagrammatic theories via graph rewrite systems. In this extended abstract, we show how the power of such rewrite systems can be greatly extended by introducing pattern graphs, which provide a means of expressing infinite families of rewrite rules where certain marked subgraphs, called !-boxes ("bang boxes", on both sides of a rule can be copied any number of times or removed. After reviewing the string graph formalism, we show how string graphs can be extended to pattern graphs and how pattern graphs and pattern rewrite rules can be instantiated to concrete string graphs and rewrite rules. We then provide examples demonstrating the expressive power of pattern graphs and how they can be applied to study interacting algebraic structures that are central to categorical quantum mechanics.

On middle cube graphs

Full Text Available We study a family of graphs related to the $n$-cube. The middle cube graph of parameter k is the subgraph of $Q_{2k-1}$ induced by the set of vertices whose binary representation has either $k-1$ or $k$ number of ones. The middle cube graphs can be obtained from the well-known odd graphs by doubling their vertex set. Here we study some of the properties of the middle cube graphs in the light of the theory of distance-regular graphs. In particular, we completely determine their spectra (eigenvalues and their multiplicities, and associated eigenvectors.

Probabilistic graphs as a conceptual and computational tool in hydrology and water management

Science.gov (United States)

Schoups, Gerrit

2014-05-01

Originally developed in the fields of machine learning and artificial intelligence, probabilistic graphs constitute a general framework for modeling complex systems in the presence of uncertainty. The framework consists of three components: 1. Representation of the model as a graph (or network), with nodes depicting random variables in the model (e.g. parameters, states, etc), which are joined together by factors. Factors are local probabilistic or deterministic relations between subsets of variables, which, when multiplied together, yield the joint distribution over all variables. 2. Consistent use of probability theory for quantifying uncertainty, relying on basic rules of probability for assimilating data into the model and expressing unknown variables as a function of observations (via the posterior distribution). 3. Efficient, distributed approximation of the posterior distribution using general-purpose algorithms that exploit model structure encoded in the graph. These attributes make probabilistic graphs potentially useful as a conceptual and computational tool in hydrology and water management (and beyond). Conceptually, they can provide a common framework for existing and new probabilistic modeling approaches (e.g. by drawing inspiration from other fields of application), while computationally they can make probabilistic inference feasible in larger hydrological models. The presentation explores, via examples, some of these benefits.

Aesthetic responses to music

2009-01-01

We explored the content and structure of the cognitive, knowledge-based concept underlying aesthetic responses to music. To this aim, we asked 290 Finnish students to verbally associate the aesthetic value of music and to write down a list of appropriate adjectives within a given time limit....... No music was presented during the task. In addition, information about participants' musical background was collected. A variety of analysis techniques was used to determine the key results of our study. The adjective "beautiful" proved to be the core item of the concept under question. Interestingly......, the adjective "touching" was often listed together with "beautiful". In addition, we found music-specific vocabulary as well as adjectives related to emotions and mood states indicating that affective processes are an essential part of aesthetic responses to music. Differences between music experts and laymen...

Grace under fire: aesthetic leadership in clinical nursing.

Science.gov (United States)

Mannix, Judy; Wilkes, Lesley; Daly, John

2015-09-01

This paper reports the results of an online descriptive survey that sought to determine nurses' perceptions of aesthetic leadership among clinical leaders in nursing. Clinical leadership has been identified as an essential component to ensuring the delivery of safe, high-quality health care. Leadership has been increasingly linked in the literature to aesthetics. However, little consideration has been given to aesthetics in relation to clinical leadership in nursing. A mixed-method, online descriptive survey. Participants were recruited via e-learning platforms and social media. A total of 66 surveys were completed, including 31 written accounts of aesthetic leadership in practice. Aesthetic leadership characteristics in clinical leaders most valued are support, communication and the approach taken to colleagues. Taking risks and challenging processes were least likely to be evident among effective clinical leaders. Aesthetic leadership is multi-dimensional and a style of leadership to positively influence the clinical workplace. Support, effective communication and taking into consideration the feelings of colleagues are important dimensions of aesthetic leadership. Aesthetic leadership represents a way for clinical leaders to create and sustain a calm and positive clinical workplace. © 2015 John Wiley & Sons Ltd.

The Role of Aesthetics for Design Phenomenology

DEFF Research Database (Denmark)

Folkmann, Mads Nygaard

The aim of the paper is to conceptualize the means and effects of different dimensions of aesthetic meaning in relation to the experience of design. In doing so, the paper combines two philosophical interests in design, design phenomenology and design aesthetics, in order to promote a framework...... for discussing the impact of aesthetic meaning construction on experience. First, the paper raises the phenomenological question of the relationship between design and experience, specifically, how design conditions experience. Second, in looking at aesthetics in terms of a) the sensual appeal of design, b...... our experience: We can look at sensual, conceptual, and contextual aesthetic dimensions of design and examine their contribution to the framing of experience, that is, how different dimensions of meaning articulation in design offer different framings of the experiences promoted by design objects...

Combinatorial and geometric aspects of Feynman graphs and Feynman integrals

Energy Technology Data Exchange (ETDEWEB)

Bergbauer, Christoph

2009-06-11

The integrals associated to Feynman graphs must have been a source of frustration for particle physicists ever since. Indeed there is a delicate difference between being able to draw a Feynman graph and being able to compute the associated Feynman integral. Although perturbation theory has brought enormous breakthroughs, many physicists turned to more abstract developments in quantum field theory, looked for other ways to produce perturbational results, or left the field entirely. Nonetheless there is a significant number of physicists, computational and theoretical, who pursue the quest for concepts and algorithms to compute and understand those integrals to higher and higher orders. Their motivation is to help test the validity of the underlying physical theory. For a mathematician, Feynman graphs and their integrals provide a rich subject in their own right, independent of their computability. It was only recently though that the work of Bloch, Esnault and Kreimer has brought a growing interest of mathematicians from various disciplines to the subject. In fact it opened up a completely new direction of research: a motivic interpretation of Feynman graphs that unites their combinatorial, geometric and arithmetic aspects. This idea had been in the air for a while, based on computational results of Broadhurst and Kreimer, and on a theorem of Belkale and Brosnan related to a conjecture of Kontsevich about the generality of the underlying motives. A prerequisite for the motivic approach is a profound understanding of renormalization that was established less recently in a modern language by Connes and Kreimer. This dissertation studies the renormalization of Feynman graphs in position space using an adapted resolution of singularities, and makes two other contributions of mostly combinatorial nature to the subject. I hope this may serve as a reference for somebody who feels comfortable with the traditional position space literature and looks for a transition to the

Network Graph Analysis of Gene-Gene Interactions in Genome-Wide Association Study Data

2012-12-01

Full Text Available Most common complex traits, such as obesity, hypertension, diabetes, and cancers, are known to be associated with multiple genes, environmental factors, and their epistasis. Recently, the development of advanced genotyping technologies has allowed us to perform genome-wide association studies (GWASs. For detecting the effects of multiple genes on complex traits, many approaches have been proposed for GWASs. Multifactor dimensionality reduction (MDR is one of the powerful and efficient methods for detecting high-order gene-gene (GxG interactions. However, the biological interpretation of GxG interactions identified by MDR analysis is not easy. In order to aid the interpretation of MDR results, we propose a network graph analysis to elucidate the meaning of identified GxG interactions. The proposed network graph analysis consists of three steps. The first step is for performing GxG interaction analysis using MDR analysis. The second step is to draw the network graph using the MDR result. The third step is to provide biological evidence of the identified GxG interaction using external biological databases. The proposed method was applied to Korean Association Resource (KARE data, containing 8838 individuals with 327,632 single-nucleotide polymorphisms, in order to perform GxG interaction analysis of body mass index (BMI. Our network graph analysis successfully showed that many identified GxG interactions have known biological evidence related to BMI. We expect that our network graph analysis will be helpful to interpret the biological meaning of GxG interactions.

Symbolic aesthetics in steel structural systems

Full Text Available The aesthetic expression and its orders are important for steel structures forming. Steel structures are a compilation of structural elements, where its shapes have standard dimensions and pre-fabricated. As the steel construction systems not only aim to achieve the functional requirements for users, but must also have the symbolic aesthetics which provides visually and cognitive expression for viewers. In this sense the research interested in expressional aesthetics in these systems and highlights the importance of attention as structural items. Therefore the visual items which related with steel structures contain some of the most powerful forms of modern architecture, steel structures with a glass cladding, agility and accuracy in manufacture of structural elements as visual items, structural interest in the forms of spaces which have long span systems or in high buildings are different forms of expression and influence. So the research focuses on the study of those expressive patterns related with the steel construction properties, including the advantages of these systems at the level of strength and firmness, flexibility and economy as well as aesthetic and expression. Accordingly, the research problem concentrated on educational shortage in the study of the structural steel system aspects concerning constructional characteristic, expressive and aesthetic features, and how to deal with them as a language bearing the symbols and meanings which have clear structural style, because it the best ways to make those systems as communication means with users, by premise that the use of expressional symbol in steel construction increases the aesthetic value. Therefore the research aims to reveal the most structural and expressive patterns by analysis the expressional means and steel structural aesthetics.

Let G be a connected graph with vertex set V(G) and edge set E(G). For every pair of vertices u,v\\in V(G), the interval I[u, v] between u and v to be the collection of all vertices that belong to some shortest u ‑ v path. A vertex s\\in V(G) strongly resolves two vertices u and v if u belongs to a shortest v ‑ s path or v belongs to a shortest u ‑ s path. A vertex set S of G is a strong resolving set of G if every two distinct vertices of G are strongly resolved by some vertex of S. The strong metric basis of G is a strong resolving set with minimal cardinality. The strong metric dimension sdim(G) of a graph G is defined as the cardinality of strong metric basis. In this paper we determine the strong metric dimension of a generalized butterfly graph, starbarbell graph, and {C}mȯ {P}n graph. We obtain the strong metric dimension of generalized butterfly graph is sdim(BFn ) = 2n ‑ 2. The strong metric dimension of starbarbell graph is sdim(S{B}{m1,{m}2,\\ldots,{m}n})={\\sum }i=1n({m}i-1)-1. The strong metric dimension of {C}mȯ {P}n graph are sdim({C}mȯ {P}n)=2m-1 for m > 3 and n = 2, and sdim({C}mȯ {P}n)=2m-2 for m > 3 and n > 2.

In this paper we develop statistical detection theory for graph signals. In particular, given two graphs, namely, a background graph that represents an usual activity and an alternative graph that represents some unusual activity, we are interested in answering the following question: To which of the two graphs does the observed graph signal fit the best? To begin with, we assume both the graphs are known, and derive an optimal Neyman-Pearson detector. Next, we derive a suboptimal detector for the case when the alternative graph is not known. The developed theory is illustrated with numerical experiments.

A Day in the Life of an Aesthetic Tāntrika: From Synaesthetic Garden to Lucid Dreaming and Spaciousness

Directory of Open Access Journals (Sweden)

Kerry Martin Skora

2018-03-01

Full Text Available This essay addresses the question of the relationship between Aesthetics and Tantra, in the world-view and life-world of Hindu Tantric visionary Abhinavagupta (ca. 975–1025 C.E. and his tradition. I respond to a classic work on Abhinavagupta’s understanding of aesthetic experience and religious experience by shifting the focus from ultimate experience to the life of a liberated being. I argue that Abhinavagupta’s blending of Aesthetics and Tantra naturally follows from his view of liberation, which re-integrates the body and senses into the religious life, and affirms the reality of the material world in which the liberated being is embedded. I recover the very humanness and boundedness of Abhinavagupta as an additional way of understanding liberation. I draw on hymns of praise, descriptions of ritual, thoughts on hermeneutics of Being, and complex metaphors, from Abhinavagupta’s tradition, and engage with various thinkers, including Performance Theorist Richard Schechner and neurologist James Austin, to flesh out complex metaphors depicting the relationship between consciousness and the world. I conclude by reflecting on similarities between the Trika model of Self, as interpreted by Abhinavagupta’s student Kṣemarāja, and lucid dreaming.

Pragmatic Graph Rewriting Modifications

We present new pragmatic constructs for easing programming in visual graph rewriting programming languages. The first is a modification to the rewriting process for nodes the host graph, where nodes specified as 'Once Only' in the LHS of a rewrite match at most once with a corresponding node in the host graph. This reduces the previously common use of tags to indicate the progress of matching in the graph. The second modification controls the application of LHS graphs, where those specified a...

Simplicial complexes of graphs

CERN Document Server

Jonsson, Jakob

2008-01-01

A graph complex is a finite family of graphs closed under deletion of edges. Graph complexes show up naturally in many different areas of mathematics, including commutative algebra, geometry, and knot theory. Identifying each graph with its edge set, one may view a graph complex as a simplicial complex and hence interpret it as a geometric object. This volume examines topological properties of graph complexes, focusing on homotopy type and homology. Many of the proofs are based on Robin Forman's discrete version of Morse theory. As a byproduct, this volume also provides a loosely defined toolbox for attacking problems in topological combinatorics via discrete Morse theory. In terms of simplicity and power, arguably the most efficient tool is Forman's divide and conquer approach via decision trees; it is successfully applied to a large number of graph and digraph complexes.

This paper describes the stapl Parallel Graph Library, a high-level framework that abstracts the user from data-distribution and parallelism details and allows them to concentrate on parallel graph algorithm development. It includes a customizable distributed graph container and a collection of commonly used parallel graph algorithms. The library introduces pGraph pViews that separate algorithm design from the container implementation. It supports three graph processing algorithmic paradigms, level-synchronous, asynchronous and coarse-grained, and provides common graph algorithms based on them. Experimental results demonstrate improved scalability in performance and data size over existing graph libraries on more than 16,000 cores and on internet-scale graphs containing over 16 billion vertices and 250 billion edges. © Springer-Verlag Berlin Heidelberg 2013.

[Patients' decision for aesthetic surgery].

Science.gov (United States)

Fansa, H; Haller, S

2011-12-01

Aesthetic surgery is a service which entails a high degree of trust. Service evaluation prior to provision is difficult for the patient. This leads to the question of how to manage the service successfully while still focusing on the medical needs. The decision to undergo an operation is not influenced by the operation itself, but by preoperative events which induce the patient to have the operation done. According to "buying decisions" for products or in service management, the decision for an aesthetic operation is extensive; the patient is highly involved and actively searching for information using different directed sources of information. The real "buying decision" consists of 5 phases: problem recognition, gathering of information, alternative education, purchase decision, and post purchase behaviour. A retrospective survey of 40 female patients who have already undergone an aesthetic operation assessed for problem recognition, which types of information were collected prior to the appointment with the surgeon, and why the patients have had the operation at our hospital. They were also asked how many alternative surgeons they had been seen before. Most of the patients had been thinking about undergoing an operation for several years. They mainly used the web for their research and were informed by other (non-aesthetic) physicians/general practitioners. Requested information was about the aesthetic results and possible problems and complications. Patients came based on web information and because of recommendations from other physicians. 60% of all interviewees did not see another surgeon and decided to have the operation because of positive patient-doctor communication and the surgeon's good reputation. Competence was considered to be the most important quality of the surgeon. However, the attribute was judged on subjective parameters. Environment, office rooms and staff were assessed as important but not very important. Costs of surgery were ranked second

Topic Model for Graph Mining.

Xuan, Junyu; Lu, Jie; Zhang, Guangquan; Luo, Xiangfeng

2015-12-01

Graph mining has been a popular research area because of its numerous application scenarios. Many unstructured and structured data can be represented as graphs, such as, documents, chemical molecular structures, and images. However, an issue in relation to current research on graphs is that they cannot adequately discover the topics hidden in graph-structured data which can be beneficial for both the unsupervised learning and supervised learning of the graphs. Although topic models have proved to be very successful in discovering latent topics, the standard topic models cannot be directly applied to graph-structured data due to the "bag-of-word" assumption. In this paper, an innovative graph topic model (GTM) is proposed to address this issue, which uses Bernoulli distributions to model the edges between nodes in a graph. It can, therefore, make the edges in a graph contribute to latent topic discovery and further improve the accuracy of the supervised and unsupervised learning of graphs. The experimental results on two different types of graph datasets show that the proposed GTM outperforms the latent Dirichlet allocation on classification by using the unveiled topics of these two models to represent graphs.

1998-01-01

The time has now come when graph theory should be part of the education of every serious student of mathematics and computer science, both for its own sake and to enhance the appreciation of mathematics as a whole. This book is an in-depth account of graph theory, written with such a student in mind; it reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. The volume grew out of the author's earlier book, Graph Theory -- An Introductory Course, but its length is well over twice that of its predecessor, allowing it to reveal many exciting new developments in the subject. Recognizing that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavor of the subject and to arouse interest. In addition to a modern treatment of the classical areas of graph theory such as coloring, matching, extremal theory, and algebraic graph theory, the book presents a detailed ...

A graph edit dictionary for correcting errors in roof topology graphs reconstructed from point clouds

Science.gov (United States)

Xiong, B.; Oude Elberink, S.; Vosselman, G.

2014-07-01

In the task of 3D building model reconstruction from point clouds we face the problem of recovering a roof topology graph in the presence of noise, small roof faces and low point densities. Errors in roof topology graphs will seriously affect the final modelling results. The aim of this research is to automatically correct these errors. We define the graph correction as a graph-to-graph problem, similar to the spelling correction problem (also called the string-to-string problem). The graph correction is more complex than string correction, as the graphs are 2D while strings are only 1D. We design a strategy based on a dictionary of graph edit operations to automatically identify and correct the errors in the input graph. For each type of error the graph edit dictionary stores a representative erroneous subgraph as well as the corrected version. As an erroneous roof topology graph may contain several errors, a heuristic search is applied to find the optimum sequence of graph edits to correct the errors one by one. The graph edit dictionary can be expanded to include entries needed to cope with errors that were previously not encountered. Experiments show that the dictionary with only fifteen entries already properly corrects one quarter of erroneous graphs in about 4500 buildings, and even half of the erroneous graphs in one test area, achieving as high as a 95% acceptance rate of the reconstructed models.

Shaping and reshaping the aesthetic brain: Emerging perspectives on the neurobiology of embodied aesthetics.

Kirsch, Louise P; Urgesi, Cosimo; Cross, Emily S

2016-03-01

Less than two decades after its inception, the burgeoning field of neuroaesthetics continues to grow in interest and momentum. Despite the biological and social importance of the human body and the attention people pay to its appearance in daily life, only recently has neuroaesthetic inquiry turned its attention to questions concerning the aesthetic appraisal of the human body. We review evidence illustrating that the complexity of aesthetic experience is reflected by dynamic interplay between brain systems involved in reward, perceptual and motor processing, with a focus on aesthetic perception involving the human body. We then evaluate work demonstrating how these systems are modulated by beholders' expertise or familiarity. Finally, we discuss seminal studies revealing the plasticity of behavioural and neural responses to beauty after perceptual and motor training. This research highlights the rich potential for neuroaesthetic inquiry to extend beyond its typical realm of the fine arts to address important questions regarding the relationship between embodiment, aesthetics and performing arts. We conclude by considering some of the criticisms and limitations of neuroaesthetics, and highlight several outstanding issues for future inquiry. Copyright © 2016 The Authors.

Introduction to quantum graphs

CERN Document Server

Berkolaiko, Gregory

2012-01-01

A "quantum graph" is a graph considered as a one-dimensional complex and equipped with a differential operator ("Hamiltonian"). Quantum graphs arise naturally as simplified models in mathematics, physics, chemistry, and engineering when one considers propagation of waves of various nature through a quasi-one-dimensional (e.g., "meso-" or "nano-scale") system that looks like a thin neighborhood of a graph. Works that currently would be classified as discussing quantum graphs have been appearing since at least the 1930s, and since then, quantum graphs techniques have been applied successfully in various areas of mathematical physics, mathematics in general and its applications. One can mention, for instance, dynamical systems theory, control theory, quantum chaos, Anderson localization, microelectronics, photonic crystals, physical chemistry, nano-sciences, superconductivity theory, etc. Quantum graphs present many non-trivial mathematical challenges, which makes them dear to a mathematician's heart.

PHOG analysis of self-similarity in aesthetic images

Amirshahi, Seyed Ali; Koch, Michael; Denzler, Joachim; Redies, Christoph

2012-03-01

In recent years, there have been efforts in defining the statistical properties of aesthetic photographs and artworks using computer vision techniques. However, it is still an open question how to distinguish aesthetic from non-aesthetic images with a high recognition rate. This is possibly because aesthetic perception is influenced also by a large number of cultural variables. Nevertheless, the search for statistical properties of aesthetic images has not been futile. For example, we have shown that the radially averaged power spectrum of monochrome artworks of Western and Eastern provenance falls off according to a power law with increasing spatial frequency (1/f2 characteristics). This finding implies that this particular subset of artworks possesses a Fourier power spectrum that is self-similar across different scales of spatial resolution. Other types of aesthetic images, such as cartoons, comics and mangas also display this type of self-similarity, as do photographs of complex natural scenes. Since the human visual system is adapted to encode images of natural scenes in a particular efficient way, we have argued that artists imitate these statistics in their artworks. In support of this notion, we presented results that artists portrait human faces with the self-similar Fourier statistics of complex natural scenes although real-world photographs of faces are not self-similar. In view of these previous findings, we investigated other statistical measures of self-similarity to characterize aesthetic and non-aesthetic images. In the present work, we propose a novel measure of self-similarity that is based on the Pyramid Histogram of Oriented Gradients (PHOG). For every image, we first calculate PHOG up to pyramid level 3. The similarity between the histograms of each section at a particular level is then calculated to the parent section at the previous level (or to the histogram at the ground level). The proposed approach is tested on datasets of aesthetic and

We introduce loose graph simulations (LGS), a new notion about labelled graphs which subsumes in an intuitive and natural way subgraph isomorphism (SGI), regular language pattern matching (RLPM) and graph simulation (GS). Being a unification of all these notions, LGS allows us to express directly...... also problems which are “mixed” instances of previous ones, and hence which would not fit easily in any of them. After the definition and some examples, we show that the problem of finding loose graph simulations is NP-complete, we provide formal translation of SGI, RLPM, and GS into LGSs, and we give...

Art Appreciation and the Method of Aesthetic Transfer

Directory of Open Access Journals (Sweden)

Zupančič Tomaž

2013-11-01

Full Text Available The method of aesthetic transfer is a modern teaching method in art education. It emphasizes the pedagogic value of the aesthetic experience. It is a comprehensive method, as it encompasses different parameters of art didactics. It affects lesson time allocation and determines content, methods, and teaching modes. It also affects motivation and final evaluation. The essence of the method of aesthetic transfer lies in transferring aesthetic messages from the artwork to students. The foundation and condition for a successful implementation of the method of aesthetic transfer is a high-quality art appreciation. There are several ways and methods for successfully developing art appreciation, the common objective of all being to allow students to see, perceive, and enjoy a work of art. Thus they enrich their artistic and aesthetic development, and establish a positive attitude towards art, while this method at the same time encourages their own artistic exploration.

Combining aesthetic with ecological values for landscape sustainability.

Yang, Dewei; Luo, Tao; Lin, Tao; Qiu, Quanyi; Luo, Yunjian

2014-01-01

Humans receive multiple benefits from various landscapes that foster ecological services and aesthetic attractiveness. In this study, a hybrid framework was proposed to evaluate ecological and aesthetic values of five landscape types in Houguanhu Region of central China. Data from the public aesthetic survey and professional ecological assessment were converted into a two-dimensional coordinate system and distribution maps of landscape values. Results showed that natural landscapes (i.e. water body and forest) contributed positively more to both aesthetic and ecological values than semi-natural and human-dominated landscapes (i.e. farmland and non-ecological land). The distribution maps of landscape values indicated that the aesthetic, ecological and integrated landscape values were significantly associated with landscape attributes and human activity intensity. To combine aesthetic preferences with ecological services, the methods (i.e. field survey, landscape value coefficients, normalized method, a two-dimensional coordinate system, and landscape value distribution maps) were employed in landscape assessment. Our results could facilitate to identify the underlying structure-function-value chain, and also improve the understanding of multiple functions in landscape planning. The situation context could also be emphasized to bring ecological and aesthetic goals into better alignment.

Aesthetic quality inference for online fashion shopping

Science.gov (United States)

Chen, Ming; Allebach, Jan

2014-03-01

On-line fashion communities in which participants post photos of personal fashion items for viewing and possible purchase by others are becoming increasingly popular. Generally, these photos are taken by individuals who have no training in photography with low-cost mobile phone cameras. It is desired that photos of the products have high aesthetic quality to improve the users' online shopping experience. In this work, we design features for aesthetic quality inference in the context of online fashion shopping. Psychophysical experiments are conducted to construct a database of the photos' aesthetic evaluation, specifically for photos from an online fashion shopping website. We then extract both generic low-level features and high-level image attributes to represent the aesthetic quality. Using a support vector machine framework, we train a predictor of the aesthetic quality rating based on the feature vector. Experimental results validate the efficacy of our approach. Metadata such as the product type are also used to further improve the result.

Trash and Aesthetics in the Hoard

Directory of Open Access Journals (Sweden)

Charmaine Eddy

2015-06-01

Full Text Available Trash and Aesthetics in the Hoard by Charmaine Eddy, Issue 7: The Aesthetics of Trash. This article examines two reality television series, Hoarders and Hoarding: Buried Alive, in terms of a variation in the understanding of the object in relation to value based upon an aesthetic tied to consumer capitalism. Object collection is viewed as a spectacle of abjection in each episode, as items that were once worthy of purchase come to produce a garbage heap within the home. The concept of “trash” is an evaluative category applied to objects over time, but it also becomes part of the therapeutic process, as hoarders are required to dispose of their things. Object-oriented ontology, or “thing theory,” provides an alternate semiology for the object, ultimately illustrating how an evaluative aesthetics of the object in these series is linked to consumer capitalism and normative patterns of consumption.

Quantum walks on quotient graphs

International Nuclear Information System (INIS)

Krovi, Hari; Brun, Todd A.

2007-01-01

A discrete-time quantum walk on a graph Γ is the repeated application of a unitary evolution operator to a Hilbert space corresponding to the graph. If this unitary evolution operator has an associated group of symmetries, then for certain initial states the walk will be confined to a subspace of the original Hilbert space. Symmetries of the original graph, given by its automorphism group, can be inherited by the evolution operator. We show that a quantum walk confined to the subspace corresponding to this symmetry group can be seen as a different quantum walk on a smaller quotient graph. We give an explicit construction of the quotient graph for any subgroup H of the automorphism group and illustrate it with examples. The automorphisms of the quotient graph which are inherited from the original graph are the original automorphism group modulo the subgroup H used to construct it. The quotient graph is constructed by removing the symmetries of the subgroup H from the original graph. We then analyze the behavior of hitting times on quotient graphs. Hitting time is the average time it takes a walk to reach a given final vertex from a given initial vertex. It has been shown in earlier work [Phys. Rev. A 74, 042334 (2006)] that the hitting time for certain initial states of a quantum walks can be infinite, in contrast to classical random walks. We give a condition which determines whether the quotient graph has infinite hitting times given that they exist in the original graph. We apply this condition for the examples discussed and determine which quotient graphs have infinite hitting times. All known examples of quantum walks with hitting times which are short compared to classical random walks correspond to systems with quotient graphs much smaller than the original graph; we conjecture that the existence of a small quotient graph with finite hitting times is necessary for a walk to exhibit a quantum speedup

Fundamentals of algebraic graph transformation

Ehrig, Hartmut; Prange, Ulrike; Taentzer, Gabriele

2006-01-01

Graphs are widely used to represent structural information in the form of objects and connections between them. Graph transformation is the rule-based manipulation of graphs, an increasingly important concept in computer science and related fields. This is the first textbook treatment of the algebraic approach to graph transformation, based on algebraic structures and category theory. Part I is an introduction to the classical case of graph and typed graph transformation. In Part II basic and advanced results are first shown for an abstract form of replacement systems, so-called adhesive high-level replacement systems based on category theory, and are then instantiated to several forms of graph and Petri net transformation systems. Part III develops typed attributed graph transformation, a technique of key relevance in the modeling of visual languages and in model transformation. Part IV contains a practical case study on model transformation and a presentation of the AGG (attributed graph grammar) tool envir...

Brain correlates of aesthetic judgment of beauty.

Jacobsen, Thomas; Schubotz, Ricarda I; Höfel, Lea; Cramon, D Yves V

2006-01-01

Functional MRI was used to investigate the neural correlates of aesthetic judgments of beauty of geometrical shapes. Participants performed evaluative aesthetic judgments (beautiful or not?) and descriptive symmetry judgments (symmetric or not?) on the same stimulus material. Symmetry was employed because aesthetic judgments are known to be often guided by criteria of symmetry. Novel, abstract graphic patterns were presented to minimize influences of attitudes or memory-related processes and to test effects of stimulus symmetry and complexity. Behavioral results confirmed the influence of stimulus symmetry and complexity on aesthetic judgments. Direct contrasts showed specific activations for aesthetic judgments in the frontomedian cortex (BA 9/10), bilateral prefrontal BA 45/47, and posterior cingulate, left temporal pole, and the temporoparietal junction. In contrast, symmetry judgments elicited specific activations in parietal and premotor areas subserving spatial processing. Interestingly, beautiful judgments enhanced BOLD signals not only in the frontomedian cortex, but also in the left intraparietal sulcus of the symmetry network. Moreover, stimulus complexity caused differential effects for each of the two judgment types. Findings indicate aesthetic judgments of beauty to rely on a network partially overlapping with that underlying evaluative judgments on social and moral cues and substantiate the significance of symmetry and complexity for our judgment of beauty.

BootGraph: probabilistic fiber tractography using bootstrap algorithms and graph theory.

Science.gov (United States)

Vorburger, Robert S; Reischauer, Carolin; Boesiger, Peter

2013-02-01

Bootstrap methods have recently been introduced to diffusion-weighted magnetic resonance imaging to estimate the measurement uncertainty of ensuing diffusion parameters directly from the acquired data without the necessity to assume a noise model. These methods have been previously combined with deterministic streamline tractography algorithms to allow for the assessment of connection probabilities in the human brain. Thereby, the local noise induced disturbance in the diffusion data is accumulated additively due to the incremental progression of streamline tractography algorithms. Graph based approaches have been proposed to overcome this drawback of streamline techniques. For this reason, the bootstrap method is in the present work incorporated into a graph setup to derive a new probabilistic fiber tractography method, called BootGraph. The acquired data set is thereby converted into a weighted, undirected graph by defining a vertex in each voxel and edges between adjacent vertices. By means of the cone of uncertainty, which is derived using the wild bootstrap, a weight is thereafter assigned to each edge. Two path finding algorithms are subsequently applied to derive connection probabilities. While the first algorithm is based on the shortest path approach, the second algorithm takes all existing paths between two vertices into consideration. Tracking results are compared to an established algorithm based on the bootstrap method in combination with streamline fiber tractography and to another graph based algorithm. The BootGraph shows a very good performance in crossing situations with respect to false negatives and permits incorporating additional constraints, such as a curvature threshold. By inheriting the advantages of the bootstrap method and graph theory, the BootGraph method provides a computationally efficient and flexible probabilistic tractography setup to compute connection probability maps and virtual fiber pathways without the drawbacks of

2015-08-01

The demand for female aesthetic labiaplasty surgery continues to rapidly increase. Several questions have been raised regarding the safety and effectiveness of female aesthetic genital surgery. The purpose of this study is to review our experience with aesthetic labiaplasty and describe the type and frequency of complications that have been experienced. A retrospective chart review was performed on all patients who had primary aesthetic labia minora reduction surgery from August 2007 to April 2014. A chart review of the electronic medical record was performed to examine demographic, procedural, and outcome data. In the study period, 113 patients underwent aesthetic labiaplasty. Of these, 29 patients (25.6%) had labiaplasty performed in combination with another procedure. A total of 15 patients (13.3%) reported transient symptoms, including swelling, bruising, and pain. There was one patient (0.8%) that experienced bleeding. Four patients (3.5%) required revision surgery. All revisions were performed to excise further tissue to address persistent redundancy or asymmetry. No major complications were reported. In our experience, aesthetic surgery of the labia minora using an edge excision technique has a very low complication rate and provides satisfactory aesthetic outcomes for our patients. More studies examining the impact of labiaplasty on a woman's self-image and quality of life would add to our understanding of the motivations and expectations of women undergoing this aesthetic surgery. This information will allow us to help our patients make well-informed decisions when considering this aesthetic genital surgery. 4 Risk. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

The Evolutionary Value of an Aesthetic Sense

Stephen Davies

2013-12-01

Full Text Available The aesthetic sense we inherited from our successful ancestors drew them toward conditions that made for survival and reproductive success and repelled them away from conditions that impacted negatively on longevity and fertility. But for them, as for us, those desirable outcomes were incidental and uncalculated. Their search was for the beautiful and sublime. Aesthetic behaviours are apparent in our forerunner species about 400,000 years ago. They sometimes made symmetrical hand axes that were then not used. We can take an aesthetic interest in more or less anything, but the aesthetic responses that are rooted in our biology include those to landscapes and environments, to non-human animals, and to the appearance and behaviour of our fellow humans.

Cognitive mechanisms for explaining dynamics of aesthetic appreciation

Science.gov (United States)

Carbon, Claus-Christian

2011-01-01

For many domains aesthetic appreciation has proven to be highly reliable. Evaluations of facial attractiveness, for instance, show high internal consistencies and impressively high inter-rater reliabilities, even across cultures. This indicates general mechanisms underlying such evaluations. It is, however, also obvious that our taste for specific objects is not always stable—in some realms such stability is hardly conceivable at all since aesthetic domains such as fashion, design, or art are inherently very dynamic. Gaining insights into the cognitive mechanisms that trigger and enable corresponding changes of aesthetic appreciation is of particular interest for psychologists as this will probably reveal essential mechanisms of aesthetic evaluations per se. The present paper develops a two-step model, dynamically adapting itself, which accounts for typical dynamics of aesthetic appreciation found in different research areas such as art history, philosophy, and psychology. The first step assumes singular creative sources creating and establishing innovative material towards which, in a second step, people adapt by integrating it into their visual habits. This inherently leads to dynamic changes of the beholders— aesthetic appreciation. PMID:23145254

Truth comes into play: Adorno, Kant and Aesthetics

Directory of Open Access Journals (Sweden)

Berta M. Pérez

2009-10-01

Full Text Available This paper departs from the verification of the centrality that, in Adorno’s recognition of the aesthetic field, the rehabilitation of its bond to knowledge and truth has. Adorno’s criticism to the Kantian aesthetic theory is, this way, reconstructed starting from his dismissal of the separation, established by Kant, between the aesthetic and the epistemological fields. This criticism, which accuses the Kantian aesthetics of subjectivism, is finally taken back to Adorno’s dissatisfaction regarding the transcendental approach, for not being dialectic. At this point, the need of determining the specificity of his own understanding of the aesthetic and dialectics becomes apparent. Surprisingly it is then discovered an unexpected proximity between his position and the one represented by the Kantian aesthetics itself, a proximity that let recognize in the latter some features which go beyond the limits of the Critical System towards the Adornian approach. But this proximity proves also the immanence and legitimacy of the (ambiguous Adornian criticism to Kant, and, as a result of this, the unsatisfactory quality of the Kantian determination of knowledge and truth.

The main tools we use here are the Cauchy-Schwarz inequality and the Ozeki inequality.

Confidence, Visual Research, and the Aesthetic Function

Directory of Open Access Journals (Sweden)

Stan Ruecker

2007-05-01

Full Text Available The goal of this article is to identify and describe one of the primary purposes of aesthetic quality in the design of computer interfaces and visualization tools. We suggest that humanists can derive advantages in visual research by acknowledging by their efforts to advance aesthetic quality that a significant function of aesthetics in this context is to inspire the user’s confidence. This confidence typically serves to create a sense of trust in the provider of the interface or tool. In turn, this increased trust may result in an increased willingness to engage with the object, on the basis that it demonstrates an attention to detail that promises to reward increased engagement. In addition to confidence, the aesthetic may also contribute to a heightened degree of satisfaction with having spent time using or investigating the object. In the realm of interface design and visualization research, we propose that these aesthetic functions have implications not only for the quality of interactions, but also for the results of the standard measures of performance and preference.

Stolen beauty: gender, aesthetics and embodiment in Brazilian drama

Directory of Open Access Journals (Sweden)

Heloisa Pontes

2008-01-01

Full Text Available Drawing from a broader research on gender inflections in the Brazilian intellectual field and in Brazilian drama, between 1940 and 1968, the article discusses the relations between aesthetics and gender, and their implications on the careers of actresses Cacilda Becker, Maria Della Costa, Tônia Carrero and Cleyde Yáconis. According to testimony of those who saw her perform on stage, Cacilda was never hampered by her less favorable physical attributes. The hypothesis is that this is due to the cunning tricks of the conventions of dramatic arts that allow the dodging of social, gender and physical constraints. Widely evoked by the media to portrait, underline or diminish women under its focus, beauty rarely features as a relevant dimension in the analysis of female trajectories. Hence the interest in discussing the subject through its refraction on the process of social construction of artistic careers.

Price Competition on Graphs

This paper extends Hotelling's model of price competition with quadratic transportation costs from a line to graphs. I propose an algorithm to calculate firm-level demand for any given graph, conditional on prices and firm locations. One feature of graph models of price competition is that spatial discontinuities in firm-level demand may occur. I show that the existence result of D'Aspremont et al.

Acyclicity in edge-colored graphs

DEFF Research Database (Denmark)

Gutin, Gregory; Jones, Mark; Sheng, Bin

2017-01-01

A walk W in edge-colored graphs is called properly colored (PC) if every pair of consecutive edges in W is of different color. We introduce and study five types of PC acyclicity in edge-colored graphs such that graphs of PC acyclicity of type i is a proper superset of graphs of acyclicity of type i......+1, i=1,2,3,4. The first three types are equivalent to the absence of PC cycles, PC closed trails, and PC closed walks, respectively. While graphs of types 1, 2 and 3 can be recognized in polynomial time, the problem of recognizing graphs of type 4 is, somewhat surprisingly, NP-hard even for 2-edge-colored...... graphs (i.e., when only two colors are used). The same problem with respect to type 5 is polynomial-time solvable for all edge-colored graphs. Using the five types, we investigate the border between intractability and tractability for the problems of finding the maximum number of internally vertex...

Graph Sampling for Covariance Estimation

KAUST Repository

Chepuri, Sundeep Prabhakar

2017-04-25

In this paper the focus is on subsampling as well as reconstructing the second-order statistics of signals residing on nodes of arbitrary undirected graphs. Second-order stationary graph signals may be obtained by graph filtering zero-mean white noise and they admit a well-defined power spectrum whose shape is determined by the frequency response of the graph filter. Estimating the graph power spectrum forms an important component of stationary graph signal processing and related inference tasks such as Wiener prediction or inpainting on graphs. The central result of this paper is that by sampling a significantly smaller subset of vertices and using simple least squares, we can reconstruct the second-order statistics of the graph signal from the subsampled observations, and more importantly, without any spectral priors. To this end, both a nonparametric approach as well as parametric approaches including moving average and autoregressive models for the graph power spectrum are considered. The results specialize for undirected circulant graphs in that the graph nodes leading to the best compression rates are given by the so-called minimal sparse rulers. A near-optimal greedy algorithm is developed to design the subsampling scheme for the non-parametric and the moving average models, whereas a particular subsampling scheme that allows linear estimation for the autoregressive model is proposed. Numerical experiments on synthetic as well as real datasets related to climatology and processing handwritten digits are provided to demonstrate the developed theory.

Magic and the aesthetic illusion.

Science.gov (United States)

Balter, Leon

2002-01-01

The aesthetic illusion is the subjective experience that the content of a work of art is reality. It has an intrinsic relation to magic, an intrapsychic maneuver oriented toward modification and control of the extraspyschic world, principally through ego functioning. Magic is ontogenetically and culturally archaic, expresses the omnipotence inherent in primary narcissism, and operates according to the logic of the primary process. Magic is a constituent of all ego functioning, usually latent in later development. It may persist as an archaic feature or may be evoked regressively in global or circumscribed ways. It causes a general disinhibition of instincts and impulses attended by a sense of confidence, exhiliration, and exuberance. The aesthetic illusion is a combination of illusions: (1) that the daydream embodied by the work of art is the beholder's own, the artist being ignored, and (2) that the artistically described protagonist is a real person with a real "world." The first illusion arises through the beholder's emotional-instinctual gratification from his or her own fantasy-memory constellations; the second comes about because the beholder, by taking the protagonist as proxy, mobilizes the subjective experience of the imaginary protagonist's "reality." The first illusion is necessary for the second to take place; the second establishes the aesthetic illusion proper. Both illusions are instances of magic. Accordingly, the aesthetic illusion is accompanied by a heady experience of excitement and euphoria. The relation among the aesthetic illusion, magic, and enthusiasm is illustrated by an analytic case, J. D. Salinger's "The Laughing Man," Woody Allen's Play It Again, Sam, Don Quixote, and the medieval Cult of the Saints.

Graphing the order of the sexes: constructing, recalling, interpreting, and putting the self in gender difference graphs.

Hegarty, Peter; Lemieux, Anthony F; McQueen, Grant

Graphs seem to connote facts more than words or tables do. Consequently, they seem unlikely places to spot implicit sexism at work. Yet, in 6 studies (N = 741), women and men constructed (Study 1) and recalled (Study 2) gender difference graphs with men's data first, and graphed powerful groups (Study 3) and individuals (Study 4) ahead of weaker ones. Participants who interpreted graph order as evidence of author "bias" inferred that the author graphed his or her own gender group first (Study 5). Women's, but not men's, preferences to graph men first were mitigated when participants graphed a difference between themselves and an opposite-sex friend prior to graphing gender differences (Study 6). Graph production and comprehension are affected by beliefs and suppositions about the groups represented in graphs to a greater degree than cognitive models of graph comprehension or realist models of scientific thinking have yet acknowledged.

Large scale graph processing is a major research area for Big Data exploration. Vertex centric programming models like Pregel are gaining traction due to their simple abstraction that allows for scalable execution on distributed systems naturally. However, there are limitations to this approach which cause vertex centric algorithms to under-perform due to poor compute to communication overhead ratio and slow convergence of iterative superstep. In this paper we introduce GoFFish a scalable sub-graph centric framework co-designed with a distributed persistent graph storage for large scale graph analytics on commodity clusters. We introduce a sub-graph centric programming abstraction that combines the scalability of a vertex centric approach with the flexibility of shared memory sub-graph computation. We map Connected Components, SSSP and PageRank algorithms to this model to illustrate its flexibility. Further, we empirically analyze GoFFish using several real world graphs and demonstrate its significant performance improvement, orders of magnitude in some cases, compared to Apache Giraph, the leading open source vertex centric implementation.

Bell inequalities for graph states

International Nuclear Information System (INIS)

Toth, G.; Hyllus, P.; Briegel, H.J.; Guehne, O.

2005-01-01

Full text: In the last years graph states have attracted an increasing interest in the field of quantum information theory. Graph states form a family of multi-qubit states which comprises many popular states such as the GHZ states and the cluster states. They also play an important role in applications. For instance, measurement based quantum computation uses graph states as resources. From a theoretical point of view, it is remarkable that graph states allow for a simple description in terms of stabilizing operators. In this contribution, we investigate the non-local properties of graph states. We derive a family of Bell inequalities which require three measurement settings for each party and are maximally violated by graph states. In turn, any graph state violates at least one of the inequalities. We show that for certain types of graph states the violation of these inequalities increases exponentially with the number of qubits. We also discuss connections to other entanglement properties such as the positively of the partial transpose or the geometric measure of entanglement. (author)

Fractal Analysis of Stealthy Pathfinding Aesthetics

Directory of Open Access Journals (Sweden)

Ron Coleman

2009-01-01

Full Text Available This paper uses a fractal model to analyze aesthetic values of a new class of obstacle-prone or “stealthy” pathfinding which seeks to avoid detection, exposure, openness, and so forth in videogames. This study is important since in general the artificial intelligence literature has given relatively little attention to aesthetic outcomes in pathfinding. The data we report, according to the fractal model, suggests that stealthy paths are statistically significantly unique in relative aesthetic value when compared to control paths. We show furthermore that paths generated with different stealth regimes are also statistically significantly unique. These conclusions are supported by statistical analysis of model results on experimental trials involving pathfinding in randomly generated, multiroom virtual worlds.

Multiple graph regularized protein domain ranking.

Science.gov (United States)

Wang, Jim Jing-Yan; Bensmail, Halima; Gao, Xin

2012-11-19

Protein domain ranking is a fundamental task in structural biology. Most protein domain ranking methods rely on the pairwise comparison of protein domains while neglecting the global manifold structure of the protein domain database. Recently, graph regularized ranking that exploits the global structure of the graph defined by the pairwise similarities has been proposed. However, the existing graph regularized ranking methods are very sensitive to the choice of the graph model and parameters, and this remains a difficult problem for most of the protein domain ranking methods. To tackle this problem, we have developed the Multiple Graph regularized Ranking algorithm, MultiG-Rank. Instead of using a single graph to regularize the ranking scores, MultiG-Rank approximates the intrinsic manifold of protein domain distribution by combining multiple initial graphs for the regularization. Graph weights are learned with ranking scores jointly and automatically, by alternately minimizing an objective function in an iterative algorithm. Experimental results on a subset of the ASTRAL SCOP protein domain database demonstrate that MultiG-Rank achieves a better ranking performance than single graph regularized ranking methods and pairwise similarity based ranking methods. The problem of graph model and parameter selection in graph regularized protein domain ranking can be solved effectively by combining multiple graphs. This aspect of generalization introduces a new frontier in applying multiple graphs to solving protein domain ranking applications.

Brennan, Connie

2014-01-01

The quest to restore a more youthful appearance by filling and volumizing facial deformities and deficiencies continues to be an ongoing pursuit in the noninvasive aesthetics market. Bruising can result from the delivery of neuromodulators and dermal fillers--common tools in the aesthetic provider's armamentarium to combat the ravages of aging. There are steps both the aesthetic provider and the client can take to minimize the potential for bruising. This article focuses on the etiology of bruising, the pharmacological and herbal agents to avoid prior to an aesthetic procedure, techniques to utilize during aesthetic procedures that lessen the potential of bruise formation, and pharmacological and herbal agents to administer after an aesthetic procedure to ultimately mitigate bruise formation.

Kaplan, Julie Bass

2015-01-01

The concept of aesthetic self-esteem was explored for utilization in the medical spa environment. The aims and purposes of the analysis were outlined. The literature review identified various uses of the self-esteem concept as well as published definitions of the word. Defining attributes were also explored and examined, including positive and negative connotations of self-esteem. Two tools were utilized to help aesthetic nurse specialists assess patients for self-esteem and assess for a possible mental illness that may present as low self-esteem. A culturally sensitive theoretical definition of self-esteem was constructed to fit the needs and environment of medical spas. A model case of this definition, as well as a borderline and contrary case, was presented. Antecedents and consequences, as well as empirical referents of the concept, were explored.

[What is beauty? : Manifest for an aesthetic character medicine].

Harth, W

2017-12-01

Aesthetic medicine has in recent decades attained a growing social significance and firm place in the medical profession image. In a short time, a variety of technical procedures and processes have been developed and applied by specialized physicians. A further leading medical discussion regarding the central question "What is beauty" is missing compared with the technologically innovative progress. Beauty is characterized by an individual and subjective pleasure. Social media and fashion trends exert a central influence on common beauty ideals and aesthetic medicine. In practice, the artificial intervention must accord to the individual personality. Therefore, the professional term Aesthetic Medicine is insufficient and should be replaced by "Aesthetic Character Medicine". The particular purpose is the aim of graceful aging and a sustained adequate result which outlasts the zeitgeist. This requires medical know how and clear aesthetic self-conception of the physician. "Aesthetic Character Medicine" can be realized in a discourse, with the 10-step plan presented in this article.

Humans uniquely appreciate aesthetics, experiencing pleasurable responses to complex stimuli that confer no clear intrinsic value for survival. However, substantial variability exists in the frequency and specificity of aesthetic responses. While pleasure from aesthetics is attributed to the neural circuitry for reward, what accounts for individual differences in aesthetic reward sensitivity remains unclear. Using a combination of survey data, behavioral and psychophysiological measures and diffusion tensor imaging, we found that white matter connectivity between sensory processing areas in the superior temporal gyrus and emotional and social processing areas in the insula and medial prefrontal cortex explains individual differences in reward sensitivity to music. Our findings provide the first evidence for a neural basis of individual differences in sensory access to the reward system, and suggest that social-emotional communication through the auditory channel may offer an evolutionary basis for music making as an aesthetically rewarding function in humans. © The Author (2016).

2012-11-19

Background: Protein domain ranking is a fundamental task in structural biology. Most protein domain ranking methods rely on the pairwise comparison of protein domains while neglecting the global manifold structure of the protein domain database. Recently, graph regularized ranking that exploits the global structure of the graph defined by the pairwise similarities has been proposed. However, the existing graph regularized ranking methods are very sensitive to the choice of the graph model and parameters, and this remains a difficult problem for most of the protein domain ranking methods.Results: To tackle this problem, we have developed the Multiple Graph regularized Ranking algorithm, MultiG-Rank. Instead of using a single graph to regularize the ranking scores, MultiG-Rank approximates the intrinsic manifold of protein domain distribution by combining multiple initial graphs for the regularization. Graph weights are learned with ranking scores jointly and automatically, by alternately minimizing an objective function in an iterative algorithm. Experimental results on a subset of the ASTRAL SCOP protein domain database demonstrate that MultiG-Rank achieves a better ranking performance than single graph regularized ranking methods and pairwise similarity based ranking methods.Conclusion: The problem of graph model and parameter selection in graph regularized protein domain ranking can be solved effectively by combining multiple graphs.

2017-01-01

Based on psychophysics’ pragmatic dualism, we trace the cognitive neuroscience of stability and variability in aesthetic experience. With regard to different domains of aesthetic processing, we touch upon the relevance of cognitive schemata for aesthetic preference. Attitudes and preferences are explored in detail. Evolutionary constraints on attitude formation or schema generation are elucidated, just as the often seemingly arbitrary influences of social, societal, and cultural nature are. A...

Canonical Labelling of Site Graphs

Directory of Open Access Journals (Sweden)

Nicolas Oury

2013-06-01

Full Text Available We investigate algorithms for canonical labelling of site graphs, i.e. graphs in which edges bind vertices on sites with locally unique names. We first show that the problem of canonical labelling of site graphs reduces to the problem of canonical labelling of graphs with edge colourings. We then present two canonical labelling algorithms based on edge enumeration, and a third based on an extension of Hopcroft's partition refinement algorithm. All run in quadratic worst case time individually. However, one of the edge enumeration algorithms runs in sub-quadratic time for graphs with "many" automorphisms, and the partition refinement algorithm runs in sub-quadratic time for graphs with "few" bisimulation equivalences. This suite of algorithms was chosen based on the expectation that graphs fall in one of those two categories. If that is the case, a combined algorithm runs in sub-quadratic worst case time. Whether this expectation is reasonable remains an interesting open problem.

Aesthetic Cartography

Science.gov (United States)

Toland, Alexandra

2017-04-01

Art theorists, Carole Gray and Heather Delday (2010) pose the question, "What might be known through creative practice that could not be known by any other means?" As a visual artist with a doctorate degree in environmental planning from the TU-Berlin's Department of Soil Protection, I have long considered this question in my work and over the years contributed an active voice to discussions on research, education, and public engagement with soil and art and soil and culture in Germany and around the world. After presenting many other examples of artists' work at international scientific symposia, I would like to present examples of some of my own artistic practice with soil mapping and soil protection issues at the 2017 EGU. In combining methods of visual art, landscape analysis, and soil mapping, I have developed a practice called Aesthetic Cartography that employs sculptural techniques, object-making, installation and performance, printing and graphic design, as well as site analysis, data mining, and map reading and interpretation. Given my background in participatory planning practices, I also integrate small-group dialogic processes in the creation and implementation of my works. The projects making up the body of works in Aesthetic Cartography are mainly focused on urban issues, including: soil sealing, inner-city watershed management, creative brownfield use, rubble substrates and leachates, foraging and urban agriculture, and envisioning sustainable cities of the future. In the session SSS1.4 - Soil, Art, and Culture I will summarize project goals, materials and methods, venues and public contexts, elements of collaboration and participation, as well as target audiences involved in several projects of the Aesthetic Cartography series. The aim of the presentation is not to give a comprehensive answer to Gray and Delday's question above, but rather to share personal insights from a professional practice that merges artistic and scientific approaches to soil

Full Text Available We titled our work “On Beauty and the Beautiful in Aesthetic Education” and we analyzed the category beautiful in function of better understanding the issues of aesthetic education.The basic point was the fact that the determination of the term beautiful is being different in both, time aspect and space aspect. Also, the authors involved in this matter have got different understanding on beautiful issue, on its essence, on its role in human development and on the development of the aesthetics and the aesthetic education.Therefore, within our work, there is an attempt to differ the approaches towards the category beautiful, to comment it, to compare it and finally to give our approach.

Lähdesmäki, Tuuli

2017-01-01

This anthology fosters an interdisciplinary dialogue between the mathematical and artistic approaches in the field where mathematical and artistic thinking and practice merge. The articles included highlight the most significant current ideas and phenomena, providing a multifaceted and extensive snapshot of the field and indicating how interdisciplinary approaches are applied in the research of various cultural and artistic phenomena. The discussions are related, for example, to the fields of aesthetics, anthropology, art history, art theory, artistic practice, cultural studies, ethno-mathematics, geometry, mathematics, new physics, philosophy, physics, study of visual illusions, and symmetry studies. Further, the book introduces a new concept: the interdisciplinary aesthetics of mathematical art, which the editors use to explain the manifold nature of the aesthetic principles intertwined in these discussions.

Aesthetic experience and the emotional content of paintings

Directory of Open Access Journals (Sweden)

Slobodan Marković

2010-03-01

Full Text Available In this study we investigated the relationship between aesthetic experience and other emotional qualities judged in paintings. Aesthetic experience was defined as an exceptional state of mind in which a person is focused on a particular object, transcending its everyday uses and meanings and losing the awareness of surroundings and even of himself/herself. In this state a person has an exceptional emotional experience, that is a feeling of unity with the object. Our basic idea is that aesthetic experience is not reducible to pleasure or a positive hedonic tone, but a person can equally be fascinated with both pleasant and unpleasant objects. In preliminary studies we specified the stimulus set of figural and semi-figural paintings, and a set of descriptors of emotions, feelings and aesthetic experience. Participants judged the paintings on descriptors (seven-point scales. Factor analysis revealed two large factors: the bipolar factor Affective Tone (descriptors on the positive pole: lovely, charming, cheerful, etc; descriptors on the negative pole: scary, disgusting, hateful etc. and Aesthetic Experience (descriptors: exceptional, profound, unique, etc.. Additional analyses have shown no significant correlation between the two factors. These findings confirmed our idea that aesthetic experience is independent of pleasure or affective attraction, and that it can be induced by both pleasant and unpleasant paintings.

Full Text Available A connected dominating set is an important notion and has many applications in routing and management of networks. Graph products have turned out to be a good model of interconnection networks. This motivated us to study the Cartesian product of graphs G with connected domination number, γc(G=2,3 and characterize such graphs. Also, we characterize the k−γ-vertex (edge critical graphs and k−γc-vertex (edge critical graphs for k=2,3 where γ denotes the domination number of G. We also discuss the vertex criticality in grids.

Graph Creation, Visualisation and Transformation

Full Text Available We describe a tool to create, edit, visualise and compute with interaction nets - a form of graph rewriting systems. The editor, called GraphPaper, allows users to create and edit graphs and their transformation rules using an intuitive user interface. The editor uses the functionalities of the TULIP system, which gives us access to a wealth of visualisation algorithms. Interaction nets are not only a formalism for the specification of graphs, but also a rewrite-based computation model. We discuss graph rewriting strategies and a language to express them in order to perform strategic interaction net rewriting.

Aesthetic value, or beauty, is important to the relationship between humans and natural environments and is, therefore, a fundamental socio-economic attribute of conservation alongside other ecosystem services. However, beauty is difficult to quantify and is not estimated well using traditional approaches to monitoring coral-reef aesthetics. To improve the estimation of ecosystem aesthetic values, we developed and implemented a novel framework used to quantify features of coral-reef aesthetics based on people's perceptions of beauty. Three observer groups with different experience to reef environments (Marine Scientist, Experienced Diver and Citizen) were virtually immersed in Australian's Great Barrier Reef (GBR) using 360° images. Perceptions of beauty and observations were used to assess the importance of eight potential attributes of reef-aesthetic value. Among these, heterogeneity, defined by structural complexity and colour diversity, was positively associated with coral-reef-aesthetic values. There were no group-level differences in the way the observer groups perceived reef aesthetics suggesting that past experiences with coral reefs do not necessarily influence the perception of beauty by the observer. The framework developed here provides a generic tool to help identify indicators of aesthetic value applicable to a wide variety of natural systems. The ability to estimate aesthetic values robustly adds an important dimension to the holistic conservation of the GBR, coral reefs worldwide and other natural ecosystems. PMID:29765676

Looking Neat on the Street. Aesthetic Labor in Public Parking Patrol

Directory of Open Access Journals (Sweden)

Dorte Boesby Dahl

2013-05-01

Full Text Available Research on aesthetic labor has been confined to service encounters in private sector industries. Aesthetic labor theory is critical of the commercialism that drives management of service labor and points to the discrimination of employees on the grounds of their “looks” that this entails. Considering the common conception today of the public sector as a service provider, application of the theory of aesthetic labor is relevant to public sector service work. But the public sector has many other purposes and mechanisms than those pertaining to increased revenues that may influence the use of aesthetic labor. This paper analyzes the aesthetic labor of Danish parking attendants in an organizational ethnography. A change management process in this organization has applied the principles of aesthetic labor actively for the purposes of diversity and health and safety. The paper shows how managers apply aesthetic labor principles to promote health and safety and workforce diversity, but also that the use of aesthetics has ambivalent purposes. Aesthetic labor is not as unequivocally applied for commercial purposes as hitherto assumed.

[Some considerations about aesthetic medicine].

Ferreira, Francisco Romão

2010-01-01

In this article, we will discuss some aspects of the construction of the meanings concerning the body from the scientific speech which was modeled based on modern thinking and became the hegemonic thinking of some sectors of the medical field. Meanings attributed to the body bring questions that come from other areas of the social life and those questions will build the aesthetic parameters which will be part of the identity construction, in the relation with the body itself, subjectivity and healthcare. We will describe some moments of the construction of the modern scientific thought and how this thought became hegemonic, influences the common sense, naturalizes identity construction and how dealing with the body, interferes in the healthcare, show a division among some sectors of the biomedicine, reinforce an specific type of medical rationality and makes an epistemic base and principle (theoretical and discursive) to some sectors connected to aesthetic medicine and aesthetic surgeries.

Foodsheds in Virtual Water Flow Networks: A Spectral Graph Theory Approach

Directory of Open Access Journals (Sweden)

Nina Kshetry

2017-06-01

Full Text Available A foodshed is a geographic area from which a population derives its food supply, but a method to determine boundaries of foodsheds has not been formalized. Drawing on the food–water–energy nexus, we propose a formal network science definition of foodsheds by using data from virtual water flows, i.e., water that is virtually embedded in food. In particular, we use spectral graph partitioning for directed graphs. If foodsheds turn out to be geographically compact, it suggests the food system is local and therefore reduces energy and externality costs of food transport. Using our proposed method we compute foodshed boundaries at the global-scale, and at the national-scale in the case of two of the largest agricultural countries: India and the United States. Based on our determination of foodshed boundaries, we are able to better understand commodity flows and whether foodsheds are contiguous and compact, and other factors that impact environmental sustainability. The formal method we propose may be used more broadly to study commodity flows and their impact on environmental sustainability.

Operative experience in aesthetic surgery is an important issue affecting plastic surgery residents. This study addresses the variability of aesthetic surgery experience during plastic surgery residency. National operative case logs of chief residents in independent/combined and integrated plastic surgery residency programs were analyzed (2011-2015). Fold differences between the bottom and top 10th percentiles of residents were calculated for each aesthetic procedure category and training model. The number of residents not achieving case minimums was also calculated. Case logs of 818 plastic surgery residents were analyzed. There was marked variability in craniofacial (range, 6.0-15.0), breast (range, 2.4-5.9), trunk/extremity (range, 3.0-16.0), and miscellaneous (range, 2.7-22.0) procedure categories. In 2015, the bottom 10th percentile of integrated and independent/combined residents did not achieve case minimums for botulinum toxin and dermal fillers. Case minimums were achieved for the other aesthetic procedure categories for all graduating years. Significant variability persists for many aesthetic procedure categories during plastic surgery residency training. Greater efforts may be needed to improve the aesthetic surgery experience of plastic surgery residents. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Classical dynamics on graphs

International Nuclear Information System (INIS)

Barra, F.; Gaspard, P.

2001-01-01

We consider the classical evolution of a particle on a graph by using a time-continuous Frobenius-Perron operator that generalizes previous propositions. In this way, the relaxation rates as well as the chaotic properties can be defined for the time-continuous classical dynamics on graphs. These properties are given as the zeros of some periodic-orbit zeta functions. We consider in detail the case of infinite periodic graphs where the particle undergoes a diffusion process. The infinite spatial extension is taken into account by Fourier transforms that decompose the observables and probability densities into sectors corresponding to different values of the wave number. The hydrodynamic modes of diffusion are studied by an eigenvalue problem of a Frobenius-Perron operator corresponding to a given sector. The diffusion coefficient is obtained from the hydrodynamic modes of diffusion and has the Green-Kubo form. Moreover, we study finite but large open graphs that converge to the infinite periodic graph when their size goes to infinity. The lifetime of the particle on the open graph is shown to correspond to the lifetime of a system that undergoes a diffusion process before it escapes

A groupie in a graph is a vertex whose degree is not less than the average degree of its neighbors. Under some mild conditions, we show that the proportion of groupies is very close to 1/2 in multitype random graphs (such as stochastic block models), which include Erd?s-R?nyi random graphs, random bipartite, and multipartite graphs as special examples. Numerical examples are provided to illustrate the theoretical results.

Quantum information processing with graph states

International Nuclear Information System (INIS)

Schlingemann, Dirk-Michael

2005-04-01

Graph states are multiparticle states which are associated with graphs. Each vertex of the graph corresponds to a single system or particle. The links describe quantum correlations (entanglement) between pairs of connected particles. Graph states were initiated independently by two research groups: On the one hand, graph states were introduced by Briegel and Raussendorf as a resource for a new model of one-way quantum computing, where algorithms are implemented by a sequence of measurements at single particles. On the other hand, graph states were developed by the author of this thesis and ReinhardWerner in Braunschweig, as a tool to build quantum error correcting codes, called graph codes. The connection between the two approaches was fully realized in close cooperation of both research groups. This habilitation thesis provides a survey of the theory of graph codes, focussing mainly, but not exclusively on the author's own research work. We present the theoretical and mathematical background for the analysis of graph codes. The concept of one-way quantum computing for general graph states is discussed. We explicitly show how to realize the encoding and decoding device of a graph code on a one-way quantum computer. This kind of implementation is to be seen as a mathematical description of a quantum memory device. In addition to that, we investigate interaction processes, which enable the creation of graph states on very large systems. Particular graph states can be created, for instance, by an Ising type interaction between next neighbor particles which sits at the points of an infinitely extended cubic lattice. Based on the theory of quantum cellular automata, we give a constructive characterization of general interactions which create a translationally invariant graph state. (orig.)

Drawing experts have better visual memory while drawing.

Science.gov (United States)

Perdreau, Florian; Cavanagh, Patrick

2015-01-01

Drawing involves frequent shifts of gaze between the original and the drawing and visual memory helps compare the original object and the drawing across these gaze shifts while creating and correcting the drawing. It remains unclear whether this memory encodes all of the object or only the features around the current drawing position and whether both the original and the copy are equally well represented. To address these questions, we designed a "drawing" experiment coupled with a change detection task. A polygon was displayed on one screen and participants had to copy it on another, with the original and the drawing presented in alternation. At unpredictable moments during the copying process, modifications were made on the drawing and the original figure (while they were not in view). Participants had to correct their drawing every time they perceived a change so that their drawing always matched the current original figure. Our results show a better memory representation of the original figure than of the drawing, with locations relevant to the current production most accurately represented. Critically, experts showed better memory for both the original and the drawing than did novices, suggesting that experts have specialized advantages for encoding visual shapes.

Fibonacci number of the tadpole graph

Directory of Open Access Journals (Sweden)

Joe DeMaio

2014-10-01

Full Text Available In 1982, Prodinger and Tichy defined the Fibonacci number of a graph G to be the number of independent sets of the graph G. They did so since the Fibonacci number of the path graph Pn is the Fibonacci number F(n+2 and the Fibonacci number of the cycle graph Cn is the Lucas number Ln. The tadpole graph Tn,k is the graph created by concatenating Cn and Pk with an edge from any vertex of Cn to a pendant of Pk for integers n=3 and k=0. This paper establishes formulae and identities for the Fibonacci number of the tadpole graph via algebraic and combinatorial methods.

On characterizing terrain visibility graphs

Directory of Open Access Journals (Sweden)

William Evans

2015-06-01

Full Text Available A terrain is an $x$-monotone polygonal line in the $xy$-plane. Two vertices of a terrain are mutually visible if and only if there is no terrain vertex on or above the open line segment connecting them. A graph whose vertices represent terrain vertices and whose edges represent mutually visible pairs of terrain vertices is called a terrain visibility graph. We would like to find properties that are both necessary and sufficient for a graph to be a terrain visibility graph; that is, we would like to characterize terrain visibility graphs.Abello et al. [Discrete and Computational Geometry, 14(3:331--358, 1995] showed that all terrain visibility graphs are “persistent”. They showed that the visibility information of a terrain point set implies some ordering requirements on the slopes of the lines connecting pairs of points in any realization, and as a step towards showing sufficiency, they proved that for any persistent graph $M$ there is a total order on the slopes of the (pseudo lines in a generalized configuration of points whose visibility graph is $M$.We give a much simpler proof of this result by establishing an orientation to every triple of vertices, reflecting some slope ordering requirements that are consistent with $M$ being the visibility graph, and prove that these requirements form a partial order. We give a faster algorithm to construct a total order on the slopes. Our approach attempts to clarify the implications of the graph theoretic properties on the ordering of the slopes, and may be interpreted as defining properties on an underlying oriented matroid that we show is a restricted type of $3$-signotope.

Network reconstruction via graph blending

Science.gov (United States)

Estrada, Rolando

2016-05-01

Graphs estimated from empirical data are often noisy and incomplete due to the difficulty of faithfully observing all the components (nodes and edges) of the true graph. This problem is particularly acute for large networks where the number of components may far exceed available surveillance capabilities. Errors in the observed graph can render subsequent analyses invalid, so it is vital to develop robust methods that can minimize these observational errors. Errors in the observed graph may include missing and spurious components, as well fused (multiple nodes are merged into one) and split (a single node is misinterpreted as many) nodes. Traditional graph reconstruction methods are only able to identify missing or spurious components (primarily edges, and to a lesser degree nodes), so we developed a novel graph blending framework that allows us to cast the full estimation problem as a simple edge addition/deletion problem. Armed with this framework, we systematically investigate the viability of various topological graph features, such as the degree distribution or the clustering coefficients, and existing graph reconstruction methods for tackling the full estimation problem. Our experimental results suggest that incorporating any topological feature as a source of information actually hinders reconstruction accuracy. We provide a theoretical analysis of this phenomenon and suggest several avenues for improving this estimation problem.

2016-06-01

Full Text Available Purpose: to justify theoretically the need for musical training of coaches in aesthetic-oriented sports. Material & Methods: theoretical analysis and generalization of scientific and methodological literature, pedagogical supervision. Results: the main directions of musical training of coaches in aesthetic-orientated sports were reviewed. It was discovered that in these types of sports coaches must have specific musical and rhythmic motor skills involving the use of musical accompaniment as a methodological technique for training sessions. The means of music and rhythmic education, which facilitate effective musical training of coaches in aesthetic-oriented sports, were determined. Conclusions: the necessity of improving the teaching methods of the subject "music and rhythmic education" as part of the musical training of coaches in aesthetic-orientated sports, was theoretically justified.

The phenomenology in the environmental aesthetic education

Noguera de Echeverri, Ana Patricia

2000-01-01

In this paper we present an abstract about our Philosophical Doctor Thesis make on Campinas University (Sao Paulo, Brazil) titled educacion estetico ambiental y fenomenologia: problemas de la educacion estetico ambiental en la modernidad. In this thesis we do a critical thinking about the epistemological model of relation subject -object on modern education, and on the other side, we work in the construction about a aesthetic - environmental education model. We propose here an aesthetization of the education, for conjoint body and world-of-life (lebenswelt) into scenarios and actors of the pedagogical process. Body and world-of-life, are two concepts of Husserl's phenomenology that open the door about the environment' s studies aesthetization and aesthetic' s studies environment, separated on modernity, between the metaphysical subject and physicality objects. Body and world-of-life -symbolic-biotic- are marginal alterities on modernity. This marginality has been a structural lead on the contemporary environmental problems

Cultural history and aesthetics of nursing care.

Siles González, José; Ruiz, Maria del Carmen Solano

2011-01-01

The aim of this study was to clarify the role of aesthetics in the organization and motivation of care through history. The guiding questions were: What values and aesthetic feelings have supported and motivated pre-professional and professional care? and Based on what structures has pre-professional and professional care been historically socialized? Primary and secondary sources were consulted, selected according to established criteria with a view to avoiding search and selection bias. Data analysis was guided by the categories: "habitus" and "logical conformism". It was found that the relation between social structures and pre-professionals (motherhood, religiosity) and professional aesthetic standards (professionalism, technologism) of care through history is evidenced in the caregiving activity of the functional unit, in the functional framework and the functional element. In conclusion, in social structures, through the socialization process, "logical conformism" and "habitus" constitute the aesthetic standards of care through feelings like motherhood, religiosity, professionalism, technologism and humanism.

Interaction graphs

Seiller, Thomas

2016-01-01

Interaction graphs were introduced as a general, uniform, construction of dynamic models of linear logic, encompassing all Geometry of Interaction (GoI) constructions introduced so far. This series of work was inspired from Girard's hyperfinite GoI, and develops a quantitative approach that should...... be understood as a dynamic version of weighted relational models. Until now, the interaction graphs framework has been shown to deal with exponentials for the constrained system ELL (Elementary Linear Logic) while keeping its quantitative aspect. Adapting older constructions by Girard, one can clearly define...... "full" exponentials, but at the cost of these quantitative features. We show here that allowing interpretations of proofs to use continuous (yet finite in a measure-theoretic sense) sets of states, as opposed to earlier Interaction Graphs constructions were these sets of states were discrete (and finite...

Groupies in multitype random graphs.

Shang, Yilun

2016-01-01

A groupie in a graph is a vertex whose degree is not less than the average degree of its neighbors. Under some mild conditions, we show that the proportion of groupies is very close to 1/2 in multitype random graphs (such as stochastic block models), which include Erdős-Rényi random graphs, random bipartite, and multipartite graphs as special examples. Numerical examples are provided to illustrate the theoretical results.

Fell runners and walking walls: towards a sociology of living landscapes and aesthetic atmospheres as an alternative to a Lakeland picturesque.

Science.gov (United States)

Nettleton, Sarah

2015-12-01

This article draws on analysis of data generated by way of an ethnography of fell running in the English Lake District and suggests that participants who have lived and run in the area for many years experience a particular mode of aesthetic. The Lake District has long been valued for its outstanding scenery represented in the aesthetic of the picturesque comprising relatively static landscapes that should be conserved. Established fell runners who have run in the area for many decades apprehend and appreciate the landscape in more complex, rooted and situated ways. The anthropologist Ingold, distinguishes between landscape and landsceppan, and this insight is instructive for grasping the way in which the runners do not simply scope scenery but work with the land: they shape it and are shaped by it. Fell runners are elements within the living environment and along with walls, sheep, becks, sun, rain--what Ingold evocatively calls the 'weather-world'--are mobile. Movement is central to their aesthetic, they enjoy not so much the scenic but rather a fellsceppan and do so through their fast eye-gait-footwork and their lively, variable occupation with the terrain. The fells infiltrate and interpenetrate the runners and movement through the fells generates a somatic aesthetic. The pleasure in turn breeds existential capital an embodied gratification that serves as an attractor that binds those who appreciate feelings of being alive with and in the fells. © London School of Economics and Political Science 2015.

The Harary index of a graph

2015-01-01

This is the first book to focus on the topological index, the Harary index, of a graph, including its mathematical properties, chemical applications and some related and attractive open problems. This book is dedicated to Professor Frank Harary (1921—2005), the grandmaster of graph theory and its applications. It has be written by experts in the field of graph theory and its applications. For a connected graph G, as an important distance-based topological index, the Harary index H(G) is defined as the sum of the reciprocals of the distance between any two unordered vertices of the graph G. In this book, the authors report on the newest results on the Harary index of a graph. These results mainly concern external graphs with respect to the Harary index; the relations to other topological indices; its properties and applications to pure graph theory and chemical graph theory; and two significant variants, i.e., additively and multiplicatively weighted Harary indices. In the last chapter, we present a number o...

The LDUA drawings are addressed in the Characterization Equipment Essential Drawings (HNF 1998). The Cone Penetrometer system drawings which are vendor drawings (not H- series) is not currently turned over to operations for deployment. The LLCE equipment was just recently assigned to Characterization Project and were not included in the original scope for this evaluation and will be addressed in the evaluation update scheduled for fiscal year 1999

[History of aesthetic rhinoplasty].

Nguyen, P S; Mazzola, R F

2014-12-01

One of the first surgical procedures described in the history of medicine is reconstructive surgery of the nose. Over the centuries, surgeons have developed techniques aimed at reconstructing noses amputated or traumatized by disease. The concept of aesthetic rhinoplasty was only introduced at the end of the 19th century. Since then, techniques have evolved toward constant ameliorations. Nowadays, this surgery is one of the most performed aesthetic procedures. Current technical sophistication is the result of over a century of history marked by many surgeons. All of these techniques derive from a detailed understanding of the anatomical nose from the surgical and artistic point of view. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Graph mining for next generation sequencing: leveraging the assembly graph for biological insights.

Science.gov (United States)

Warnke-Sommer, Julia; Ali, Hesham

2016-05-06

The assembly of Next Generation Sequencing (NGS) reads remains a challenging task. This is especially true for the assembly of metagenomics data that originate from environmental samples potentially containing hundreds to thousands of unique species. The principle objective of current assembly tools is to assemble NGS reads into contiguous stretches of sequence called contigs while maximizing for both accuracy and contig length. The end goal of this process is to produce longer contigs with the major focus being on assembly only. Sequence read assembly is an aggregative process, during which read overlap relationship information is lost as reads are merged into longer sequences or contigs. The assembly graph is information rich and capable of capturing the genomic architecture of an input read data set. We have developed a novel hybrid graph in which nodes represent sequence regions at different levels of granularity. This model, utilized in the assembly and analysis pipeline Focus, presents a concise yet feature rich view of a given input data set, allowing for the extraction of biologically relevant graph structures for graph mining purposes. Focus was used to create hybrid graphs to model metagenomics data sets obtained from the gut microbiomes of five individuals with Crohn's disease and eight healthy individuals. Repetitive and mobile genetic elements are found to be associated with hybrid graph structure. Using graph mining techniques, a comparative study of the Crohn's disease and healthy data sets was conducted with focus on antibiotics resistance genes associated with transposase genes. Results demonstrated significant differences in the phylogenetic distribution of categories of antibiotics resistance genes in the healthy and diseased patients. Focus was also evaluated as a pure assembly tool and produced excellent results when compared against the Meta-velvet, Omega, and UD-IDBA assemblers. Mining the hybrid graph can reveal biological phenomena captured

TrajGraph: A Graph-Based Visual Analytics Approach to Studying Urban Network Centralities Using Taxi Trajectory Data.

Science.gov (United States)

Huang, Xiaoke; Zhao, Ye; Yang, Jing; Zhang, Chong; Ma, Chao; Ye, Xinyue

2016-01-01

We propose TrajGraph, a new visual analytics method, for studying urban mobility patterns by integrating graph modeling and visual analysis with taxi trajectory data. A special graph is created to store and manifest real traffic information recorded by taxi trajectories over city streets. It conveys urban transportation dynamics which can be discovered by applying graph analysis algorithms. To support interactive, multiscale visual analytics, a graph partitioning algorithm is applied to create region-level graphs which have smaller size than the original street-level graph. Graph centralities, including Pagerank and betweenness, are computed to characterize the time-varying importance of different urban regions. The centralities are visualized by three coordinated views including a node-link graph view, a map view and a temporal information view. Users can interactively examine the importance of streets to discover and assess city traffic patterns. We have implemented a fully working prototype of this approach and evaluated it using massive taxi trajectories of Shenzhen, China. TrajGraph's capability in revealing the importance of city streets was evaluated by comparing the calculated centralities with the subjective evaluations from a group of drivers in Shenzhen. Feedback from a domain expert was collected. The effectiveness of the visual interface was evaluated through a formal user study. We also present several examples and a case study to demonstrate the usefulness of TrajGraph in urban transportation analysis.

Temporal Representation in Semantic Graphs

Energy Technology Data Exchange (ETDEWEB)

Levandoski, J J; Abdulla, G M

2007-08-07

A wide range of knowledge discovery and analysis applications, ranging from business to biological, make use of semantic graphs when modeling relationships and concepts. Most of the semantic graphs used in these applications are assumed to be static pieces of information, meaning temporal evolution of concepts and relationships are not taken into account. Guided by the need for more advanced semantic graph queries involving temporal concepts, this paper surveys the existing work involving temporal representations in semantic graphs.

Full Text Available After the success of GNSS (Global Navigational Satellite Systems and navigation services for public streets, indoor seems to be the next big development in navigational services, relying on RTLS – Real Time Locating Services (e.g. WIFI and allowing seamless navigation. In contrast to navigation and routing services on public streets, seamless navigation will cause an additional challenge: how to make routing data accessible to defined users or restrict access rights for defined areas or only to parts of the graph to a defined user group? The paper will present case studies and data from literature, where seamless and especially indoor navigation solutions are presented (hospitals, industrial complexes, building sites, but the problem of restricted access rights was only touched from a real world, but not a technical perspective. The analysis of case studies will show, that the objective of navigation and the different target groups for navigation solutions will demand well defined access rights and require solutions, how to make only parts of a graph to a user or application available to solve a navigational task. The paper will therefore introduce the concept of private graphs, which is defined as a graph for navigational purposes covering the street, road or floor network of an area behind a public street and suggest different approaches how to make graph data for navigational purposes available considering access rights and data protection, privacy and security issues as well.

Aesthetics of movement with sight disabled children - pilot study

2010-01-01

Full Text Available The aim of the study was to establish the aesthetics of movement in people with vision defects. This knowledge will provide tools to improve the methodology of study in the area of assessment of movement aesthetics in people with disabilities. In order to establish its level a test was used which measured its selected elements such as precision, rhythm, harmony, fluidity and speed. The aesthetics of movement was assessed using exercise tests which were to represent the components of aesthetics of movement. Individual tests were carried out on blind and partially sighted children aged 6 to 15 years and on a group of healthy children of the same age. Using the test tasks a general indicator of movement aesthetics in blind children was obtained. The participants of the study were 145 children from four School and Education Centres for Blind Children in Poland and the control group consisted of 310 children from a primary school in Poznań. The studies confirmed a lower level of movement aesthetics in children with vision defects, but the differences in groups between the partially sighted children and children with correct vision were definitely smaller. A higher level of aesthetics of movement characterised children from older groups irrespective of their sex. The best developed property in blind and partially sighted children was precision.

Integer Flows and Circuit Covers of Graphs and Signed Graphs

Science.gov (United States)

Cheng, Jian

The work in Chapter 2 is motivated by Tutte and Jaeger's pioneering work on converting modulo flows into integer-valued flows for ordinary graphs. For a signed graphs (G, sigma), we first prove that for each k ∈ {2, 3}, if (G, sigma) is (k - 1)-edge-connected and contains an even number of negative edges when k = 2, then every modulo k-flow of (G, sigma) can be converted into an integer-valued ( k + 1)-ow with a larger or the same support. We also prove that if (G, sigma) is odd-(2p+1)-edge-connected, then (G, sigma) admits a modulo circular (2 + 1/ p)-flows if and only if it admits an integer-valued circular (2 + 1/p)-flows, which improves all previous result by Xu and Zhang (DM2005), Schubert and Steffen (EJC2015), and Zhu (JCTB2015). Shortest circuit cover conjecture is one of the major open problems in graph theory. It states that every bridgeless graph G contains a set of circuits F such that each edge is contained in at least one member of F and the length of F is at most 7/5∥E(G)∥. This concept was recently generalized to signed graphs by Macajova et al. (JGT2015). In Chapter 3, we improve their upper bound from 11∥E( G)∥ to 14/3 ∥E(G)∥, and if G is 2-edgeconnected and has even negativeness, then it can be further reduced to 11/3 ∥E(G)∥. Tutte's 3-flow conjecture has been studied by many graph theorists in the last several decades. As a new approach to this conjecture, DeVos and Thomassen considered the vectors as ow values and found that there is a close relation between vector S1-flows and integer 3-NZFs. Motivated by their observation, in Chapter 4, we prove that if a graph G admits a vector S1-flow with rank at most two, then G admits an integer 3-NZF. The concept of even factors is highly related to the famous Four Color Theorem. We conclude this dissertation in Chapter 5 with an improvement of a recent result by Chen and Fan (JCTB2016) on the upperbound of even factors. We show that if a graph G contains an even factor, then it

Mechanical properties and aesthetics of FRP orthodontic wire fabricated by hot drawing.

The FRP wires 0.5 mm in diameter with a multiple fiber structure were fabricated by drawing the fiber polymer complex at 250 degrees C for an esthetic, transparent orthodontic wire. Biocompatible CaO-P2O5-SiO2-Al2O3 (CPSA) glass fibers of 8-20 microm in diameter were oriented unidirectionally in the longitudinal direction in PMMA matrix. The mechanical properties were investigated by 3-point flexural test. The FRP wire showed sufficient strength and a very good elastic recovery after deformation. Young's modulus and the flexural load at deflection 1 mm were nearly independent of the fiber diameter and linearly increased with the fiber fraction. The dependence on fiber fraction obeys well the rule of mixture. This FRP wire could cover the range of strength corresponding to the conventional metal orthodontic wires from Ni-Ti used in the initial stage of orthodontic treatments to Co-Cr used in the final stage by changing the volume ratio of glass fibers with the same external diameter. The estheticity in external appearance was excellent. Thus the new FRP wire can satisfy both mechanical properties necessary for an orthodontic wire and enough estheticity, which was not possible for the conventional metal wire.

Towards a theory of geometric graphs

CERN Document Server

Pach, Janos

2004-01-01

The early development of graph theory was heavily motivated and influenced by topological and geometric themes, such as the Konigsberg Bridge Problem, Euler's Polyhedral Formula, or Kuratowski's characterization of planar graphs. In 1936, when Denes Konig published his classical Theory of Finite and Infinite Graphs, the first book ever written on the subject, he stressed this connection by adding the subtitle Combinatorial Topology of Systems of Segments. He wanted to emphasize that the subject of his investigations was very concrete: planar figures consisting of points connected by straight-line segments. However, in the second half of the twentieth century, graph theoretical research took an interesting turn. In the most popular and most rapidly growing areas (the theory of random graphs, Ramsey theory, extremal graph theory, algebraic graph theory, etc.), graphs were considered as abstract binary relations rather than geometric objects. Many of the powerful techniques developed in these fields have been su...

Aesthetic Band, Reception Theory and Sociology of Reading

Directory of Open Access Journals (Sweden)

Marcin Rychlewski

2010-01-01

Full Text Available The aesthetic band – in contrast to the bandwidth, i.e. the distribution channel – is a socially and historically conditioned cluster of aesthetic expectations presented by readers-buyers, represented by their majority, which in the egalitarian, post-modern, and free market society, determines the shape of the publishing market and the circuits it consists of. The author believes that the aesthetic band should be analyzed in the context of both individual and collective expectations of the reading audience in relation to the book content and its subject-matter, as well as in relation to the literary and non-literary production. In the last part of the paper, the author puts forward a proposition that the aesthetic band might be considered as a tool of ideology.

We analyse a continuous-time quantum walk on a chimera graph, which is a graph of choice for designing quantum annealers, and we discover beautiful quantum walk features such as localization that starkly distinguishes classical from quantum behaviour. Motivated by technological thrusts, we study continuous-time quantum walk on enhanced variants of the chimera graph and on diminished chimera graph with a random removal of vertices. We explain the quantum walk by constructing a generating set for a suitable subgroup of graph isomorphisms and corresponding symmetry operators that commute with the quantum walk Hamiltonian; the Hamiltonian and these symmetry operators provide a complete set of labels for the spectrum and the stationary states. Our quantum walk characterization of the chimera graph and its variants yields valuable insights into graphs used for designing quantum-annealers.

Joint action aesthetics.

Staci Vicary

Full Text Available Synchronized movement is a ubiquitous feature of dance and music performance. Much research into the evolutionary origins of these cultural practices has focused on why humans perform rather than watch or listen to dance and music. In this study, we show that movement synchrony among a group of performers predicts the aesthetic appreciation of live dance performances. We developed a choreography that continuously manipulated group synchronization using a defined movement vocabulary based on arm swinging, walking and running. The choreography was performed live to four audiences, as we continuously tracked the performers' movements, and the spectators' affective responses. We computed dynamic synchrony among performers using cross recurrence analysis of data from wrist accelerometers, and implicit measures of arousal from spectators' heart rates. Additionally, a subset of spectators provided continuous ratings of enjoyment and perceived synchrony using tablet computers. Granger causality analyses demonstrate predictive relationships between synchrony, enjoyment ratings and spectator arousal, if audiences form a collectively consistent positive or negative aesthetic evaluation. Controlling for the influence of overall movement acceleration and visual change, we show that dance communicates group coordination via coupled movement dynamics among a group of performers. Our findings are in line with an evolutionary function of dance-and perhaps all performing arts-in transmitting social signals between groups of people. Human movement is the common denominator of dance, music and theatre. Acknowledging the time-sensitive and immediate nature of the performer-spectator relationship, our study makes a significant step towards an aesthetics of joint actions in the performing arts.

Theory books and method books within the field of web design mainly focus on the technical and functional aspects of the construction of web design. There is a lack of a model which weighs the analysis of the visual and aesthetic aspects against the the functional and technical aspects of web...... design. With a point of departure in Roman Jakobson's linguistic communication model, the reader is introduced to a model which covers the communication aspects, the visual aspects, the aesthetic aspects and the net specific aspects of the analysis of media products. The aesthetic aspects rank low...... in the eyes of the media producers even though the most outstanding media products often obtained their success due to aesthetic phenomena. The formal aesthetic function and the inexpressible aesthetic function have therefore been prioritised in the model in regard to the construction and analysis of media...

Towards a sensorimotor aesthetics of performing art.

Calvo-Merino, B; Jola, C; Glaser, D E; Haggard, P

2008-09-01

The field of neuroaesthetics attempts to identify the brain processes underlying aesthetic experience, including but not limited to beauty. Previous neuroaesthetic studies have focussed largely on paintings and music, while performing arts such as dance have been less studied. Nevertheless, increasing knowledge of the neural mechanisms that represent the bodies and actions of others, and which contribute to empathy, make a neuroaesthetics of dance timely. Here, we present the first neuroscientific study of aesthetic perception in the context of the performing arts. We investigated brain areas whose activity during passive viewing of dance stimuli was related to later, independent aesthetic evaluation of the same stimuli. Brain activity of six naïve male subjects was measured using fMRI, while they watched 24 dance movements, and performed an irrelevant task. In a later session, participants rated each movement along a set of established aesthetic dimensions. The ratings were used to identify brain regions that were more active when viewing moves that received high average ratings than moves that received low average ratings. This contrast revealed bilateral activity in the occipital cortices and in right premotor cortex. Our results suggest a possible role of visual and sensorimotor brain areas in an automatic aesthetic response to dance. This sensorimotor response may explain why dance is widely appreciated in so many human cultures.

Aesthetic Appreciation, Ethics, and 9/11

Directory of Open Access Journals (Sweden)

2008-01-01

Full Text Available There have been numerous critical articles on what really happened on the otherwise beautiful morning of 11 September 2001. Beyond doubt, the bulk of the critical responses to the terrorist attacks focused on the ethical and humanitarian, or rather the unethical and inhumane implications of the atrocious act, leaving no room for any philosophical reflection on the potential assessment or reception of the event from the perspective of art and aesthetics. The few years that have gone by since 2001 have provided us with some a sense of emotional detachment from the horror of that day, a detachment that may have awakened our aesthetic and artistic instincts with regard to the attacks themselves as well as their visual representation. Chronological distance renders an unprejudiced and independent stance more possible now than ever. It also allows us to reconsider our initial politically correct and ethically justified repulsion of the efforts made by a few artists to aestheticize 9/11. Such repulsion, however, was associated with the delusion that by denouncing aesthetics we were really securing the prevalence of politics, morality and ethical responsibility in a terror-afflicted society. My point in this paper is that there is a need for aesthetic appreciation when contemplating a violent event such as the 9/11 terrorist attacks. What is more, appreciation of the beautiful, even in case of a 9/11, seems necessary because it is a key to establishing an ethical stance towards terror, life, and art. It should be stressed that independent aesthetic experience is not important in itself but is a means of cultivating an authentic moral and ethical judgment.

Full Text Available The research analyzes the aesthetic dimension on teaching about natural environment on Ecology disciplines. The semiotics of Charles Sanders Peirce guided data analysis, regarding to suggested values on the answers of interviewees. The analysis has revealed that, in terms of methodological approaches, Ecology instructors tend to valorize scientific and objective criteria, demonstrating a certain embarrassment on including aesthetic dimension in their teaching, although they recognize the relevance of aesthetic dimension for ethic implications on teaching and for the conservation of natural environment.

Full Text Available Consider the result of a soccer league competition where n teams play each other exactly once. A team gets three points for each win and one point for each draw. The total score obtained by each team vi is called the f-score of vi and is denoted by fi. The sequences of all f-scores [fi]i=1n$\\left[ {{\\rm{f}}_{\\rm{i}} } \\right]_{{\\rm{i}} = 1}^{\\rm{n}} $ arranged in non-decreasing order is called the f-score sequence of the competition. We raise the following problem: Which sequences of non-negative integers in non-decreasing order is a football sequence, that is the outcome of a soccer league competition. We model such a competition by an oriented graph with teams represented by vertices in which the teams play each other once, with an arc from team u to team v if and only if u defeats v. We obtain some necessary conditions for football sequences and some characterizations under restrictions.

2018-03-01

Place-of-Interest (POI) summarization by aesthetics evaluation can recommend a set of POI images to the user and it is significant in image retrieval. In this paper, we propose a system that summarizes a collection of POI images regarding both aesthetics and diversity of the distribution of cameras. First, we generate visual albums by a coarse-to-fine POI clustering approach and then generate 3D models for each album by the collected images from social media. Second, based on the 3D to 2D projection relationship, we select candidate photos in terms of the proposed crowd source saliency model. Third, in order to improve the performance of aesthetic measurement model, we propose a crowd-sourced saliency detection approach by exploring the distribution of salient regions in the 3D model. Then, we measure the composition aesthetics of each image and we explore crowd source salient feature to yield saliency map, based on which, we propose an adaptive image adoption approach. Finally, we combine the diversity and the aesthetics to recommend aesthetic pictures. Experimental results show that the proposed POI summarization approach can return images with diverse camera distributions and aesthetics.

DrawFromDrawings: 2D Drawing Assistance via Stroke Interpolation with a Sketch Database.

Science.gov (United States)

Matsui, Yusuke; Shiratori, Takaaki; Aizawa, Kiyoharu

2017-07-01

We present DrawFromDrawings, an interactive drawing system that provides users with visual feedback for assistance in 2D drawing using a database of sketch images. Following the traditional imitation and emulation training from art education, DrawFromDrawings enables users to retrieve and refer to a sketch image stored in a database and provides them with various novel strokes as suggestive or deformation feedback. Given regions of interest (ROIs) in the user and reference sketches, DrawFromDrawings detects as-long-as-possible (ALAP) stroke segments and the correspondences between user and reference sketches that are the key to computing seamless interpolations. The stroke-level interpolations are parametrized with the user strokes, the reference strokes, and new strokes created by warping the reference strokes based on the user and reference ROI shapes, and the user study indicated that the interpolation could produce various reasonable strokes varying in shapes and complexity. DrawFromDrawings allows users to either replace their strokes with interpolated strokes (deformation feedback) or overlays interpolated strokes onto their strokes (suggestive feedback). The other user studies on the feedback modes indicated that the suggestive feedback enabled drawers to develop and render their ideas using their own stroke style, whereas the deformation feedback enabled them to finish the sketch composition quickly.

Graph Quasicontinuous Functions and Densely Continuous Forms

Full Text Available Let $X, Y$ be topological spaces. A function $f: X \\to Y$ is said to be graph quasicontinuous if there is a quasicontinuous function $g: X \\to Y$ with the graph of $g$ contained in the closure of the graph of $f$. There is a close relation between the notions of graph quasicontinuous functions and minimal usco maps as well as the notions of graph quasicontinuous functions and densely continuous forms. Every function with values in a compact Hausdorff space is graph quasicontinuous; more generally every locally compact function is graph quasicontinuous.

Book review: Spilleregler og Spillerom. Tradisjonens Estetikk (Rules and Leeway: The Aesthetics of Tradition.

Directory of Open Access Journals (Sweden)

Siri Homlong

2013-01-01

Full Text Available Mikkel B. Tin is interested in the aesthetic dimensions of art in general and of folk art in particular. In the book Rules and Leeway: The Aesthetics of Tradition, he highlights the creative processes that are driven by individual relations to aesthetics and craftsmanship in traditional crafts and design. His goal is to examine tradition and art at their meeting point, a meeting point he names the ‘tradition of aesthetics’. As signalled in the book’s title, there are in this context some limits to deal with—rules, but also a personal freedom we all expect that arts need, i.e., the expression of self.The book provides many empirical examples of how various practitioners relate to traditions. Tin present  studies of the Czech artist Tomas Smetana’s drawings, embroidered collars from East Telemark in Norway, the carved pattern on the wooden porches of Romania, towels from Ukraine, and wireworks from Slovakia. Finally, he also offers rules and scope for spray graffiti, again from an international perspective. The book contains a wealth of pictorial material, descriptions of variations in pattern, colour and materials used in various works, as well as local and international comparative analyses of these works.I find the book interesting because Tin turns the discussion away from the view of traditional craftsmanship as copying and not contributing to the development of individual creative abilities. He discusses how, from the traditional expressions of different materials, we can both learn something and also develop our own expressions. Tin’s message is that taking up a tradition does not mean to copy it, but to play along with others within a certain scope where the individual’s own experiences influence the aesthetic result. I enjoyed the associations with card or board games that proceed from a set of rules. What moves you make or what cards you put on the table depend on the situation and the other players, but also the

Sublimity and beauty: A view from nursing aesthetics.

Science.gov (United States)

Siles-González, José; Solano-Ruiz, Carmen

2016-03-01

Several authors have focused on the aesthetics of nursing care from diverse perspectives; however, there are few studies about the sublime and the beautiful in nursing. To identify beautiful and sublime moments in the context of the aesthetics of nursing care. A theoretical reflection has been contemplated about sublime and beautiful values in the context of the aesthetics of nursing care from the cultural history perspective. For that purpose, a revision of this issue has been completed. The terms 'beautiful' and 'sublime' have been analysed to identify the characteristics of both in the context of nursing care. We have followed all ethical requirements regarding the sources, conducting research and authorship. There is no conflict of interest in this paper. With aesthetic knowledge, the nurse expresses the artistic nature of nursing care by appreciating the act of caring for individuals. The sublime is a complex phenomenon, since apparently contrary feelings are interwoven. Nursing care is an art with an anthropological object-subject on which the 'artist' applies their prior knowledge and skills. Feelings and emotions that develop during the clinical nursing practice - especially at times sublime and beautiful, aesthetic - constitute experiences which are professionally significant. © The Author(s) 2015.

Jacques Joseph: Father of modern aesthetic surgery

Directory of Open Access Journals (Sweden)

Bhattacharya Surajit

2008-10-01

Full Text Available When we review the history of modern aesthetic surgery, a name that stands out as bright as a beacon and precious as gold is undoubtedly that of Jacques Joseph. A surgeon, par excellence, far ahead of his time, who chose to think out of the box, Joseph, despite all odds set out to give respectability to Aesthetic Surgery without depriving it of any scientific core values. By his words and deeds proved beyond doubt that only the very best in the field of reconstructive surgery, can visualize the hidden perfection in imperfection and formulate a treatment plan and a surgical strategy to achieve that elusive perfection. The rich surgical literature that he has left behind, the wealth of surgical instruments that he had designed and above all a way of thinking that he propagated, that aesthetic surgery is not frivolous but very serious endeavor, and treating the psychology of the patient is as important as treating his disease, undoubtedly makes him the revered ′Father of Modern Aesthetic Surgery′.

Coloring sums of extensions of certain graphs

Directory of Open Access Journals (Sweden)

Johan Kok

2017-12-01

Full Text Available We recall that the minimum number of colors that allow a proper coloring of graph $G$ is called the chromatic number of $G$ and denoted $\\chi(G$. Motivated by the introduction of the concept of the $b$-chromatic sum of a graph the concept of $\\chi'$-chromatic sum and $\\chi^+$-chromatic sum are introduced in this paper. The extended graph $G^x$ of a graph $G$ was recently introduced for certain regular graphs. This paper furthers the concepts of $\\chi'$-chromatic sum and $\\chi^+$-chromatic sum to extended paths and cycles. Bipartite graphs also receive some attention. The paper concludes with patterned structured graphs. These last said graphs are typically found in chemical and biological structures.

On a conjecture concerning helly circle graphs

Directory of Open Access Journals (Sweden)

Durán Guillermo

2003-01-01

Full Text Available We say that G is an e-circle graph if there is a bijection between its vertices and straight lines on the cartesian plane such that two vertices are adjacent in G if and only if the corresponding lines intersect inside the circle of radius one. This definition suggests a method for deciding whether a given graph G is an e-circle graph, by constructing a convenient system S of equations and inequations which represents the structure of G, in such a way that G is an e-circle graph if and only if S has a solution. In fact, e-circle graphs are exactly the circle graphs (intersection graphs of chords in a circle, and thus this method provides an analytic way for recognizing circle graphs. A graph G is a Helly circle graph if G is a circle graph and there exists a model of G by chords such that every three pairwise intersecting chords intersect at the same point. A conjecture by Durán (2000 states that G is a Helly circle graph if and only if G is a circle graph and contains no induced diamonds (a diamond is a graph formed by four vertices and five edges. Many unsuccessful efforts - mainly based on combinatorial and geometrical approaches - have been done in order to validate this conjecture. In this work, we utilize the ideas behind the definition of e-circle graphs and restate this conjecture in terms of an equivalence between two systems of equations and inequations, providing a new, analytic tool to deal with it.

A graph-based method for fitting planar B-spline curves with intersections

Directory of Open Access Journals (Sweden)

Pengbo Bo

2016-01-01

Full Text Available The problem of fitting B-spline curves to planar point clouds is studied in this paper. A novel method is proposed to deal with the most challenging case where multiple intersecting curves or curves with self-intersection are necessary for shape representation. A method based on Delauney Triangulation of data points is developed to identify connected components which is also capable of removing outliers. A skeleton representation is utilized to represent the topological structure which is further used to create a weighted graph for deciding the merging of curve segments. Different to existing approaches which utilize local shape information near intersections, our method considers shape characteristics of curve segments in a larger scope and is thus capable of giving more satisfactory results. By fitting each group of data points with a B-spline curve, we solve the problems of curve structure reconstruction from point clouds, as well as the vectorization of simple line drawing images by drawing lines reconstruction.

Social Factors in Aesthetics: Social Conformity Pressure and a Sense of Being Watched Affect Aesthetic Judgments.

Science.gov (United States)

Hesslinger, Vera M; Carbon, Claus-Christian; Hecht, Heiko

2017-01-01

The present study is a first attempt to experimentally test the impact of two specific social factors, namely social conformity pressure and a sense of being watched, on participants' judgments of the artistic quality of aesthetic objects. We manipulated conformity pressure with a test form in which a photograph of each stimulus was presented together with unanimously low (downward pressure) or high quality ratings (upward pressure) of three would-be previous raters. Participants' sense of being watched was manipulated by testing each of them in two settings, one of which contained an eyespots stimulus. Both social factors significantly affected the participants' judgments-unexpectedly, however, with conformity pressure only working in the downward direction and eyespots leading to an overall downward shift in participants' judgments. Our findings indicate the relevance of including explicit and implicit social factors in aesthetics research, thus also reminding us of the limitations of overly reductionist approaches to investigating aesthetic perception and experience.

Comparison between state graphs and fault trees for sequential and repairable systems

International Nuclear Information System (INIS)

Soussan, D.; Saignes, P.

1996-01-01

In French PSA (Probabilistic Safety Assessment) 1300 for the 1300 Mwe PWR plants carried out by EDF, sequential and reparable systems are modeled with state graphs. This method is particularly convenient for modeling dynamic systems with long-term missions but induces a bad traceability and understandability of models. In the objective of providing elements for rewriting PSA 1300 with only boolean models, EDF has asked CEA to participate to a methodological study. The aim is to carry out a feasibility study of transposition of state graphs models into fault trees on Component Cooling System and Essential Service Water System (CCS/ESWS) and to draw a methodological guide for transposition. The study realized on CCS/ESWS involves two main axes: quantification of cold source loss (as an accident sequence initiating event, called H1); quantification of the CCS/ESWS missions in accident sequences. The subject of this article is to show that this transformation is applicable with minimum distortions of the results and to determine the hypotheses, the conditions and the limits of application of this conversion.

Elena Nechita

2010-06-01

Full Text Available During the last three decades, different types of decompositions have been processed in the field of graph theory. Among these we mention: decompositions based on the additivity of some characteristics of the graph, decompositions where the adjacency law between the subsets of the partition is known, decompositions where the subgraph induced by every subset of the partition must have predeterminate properties, as well as combinations of such decompositions. In this paper we characterize threshold graphs using the weakly decomposition, determine: density and stability number, Wiener index and Wiener polynomial for threshold graphs.

Hierarchy of modular graph identities

The low energy expansion of Type II superstring amplitudes at genus one is organized in terms of modular graph functions associated with Feynman graphs of a conformal scalar field on the torus. In earlier work, surprising identities between two-loop graphs at all weights, and between higher-loop graphs of weights four and five were constructed. In the present paper, these results are generalized in two complementary directions. First, all identities at weight six and all dihedral identities at weight seven are obtained and proven. Whenever the Laurent polynomial at the cusp is available, the form of these identities confirms the pattern by which the vanishing of the Laurent polynomial governs the full modular identity. Second, the family of modular graph functions is extended to include all graphs with derivative couplings and worldsheet fermions. These extended families of modular graph functions are shown to obey a hierarchy of inhomogeneous Laplace eigenvalue equations. The eigenvalues are calculated analytically for the simplest infinite sub-families and obtained by Maple for successively more complicated sub-families. The spectrum is shown to consist solely of eigenvalues s(s−1) for positive integers s bounded by the weight, with multiplicities which exhibit rich representation-theoretic patterns.

On the centrality of some graphs

Vecdi Aytac

2017-10-01

Full Text Available A central issue in the analysis of complex networks is the assessment of their stability and vulnerability. A variety of measures have been proposed in the literature to quantify the stability of networks and a number of graph-theoretic parameters have been used to derive formulas for calculating network reliability. Different measures for graph vulnerability have been introduced so far to study different aspects of the graph behavior after removal of vertices or links such as connectivity, toughness, scattering number, binding number, residual closeness and integrity. In this paper, we consider betweenness centrality of a graph. Betweenness centrality of a vertex of a graph is portion of the shortest paths all pairs of vertices passing through a given vertex. In this paper, we obtain exact values for betweenness centrality for some wheel related graphs namely gear, helm, sunflower and friendship graphs.

In recent years, there has been a huge growth in the amount of genomic data available as reads generated from various genome sequencers. The number of reads generated can be huge, ranging from hundreds to billions of nucleotide, each varying in size. Assembling such large amounts of data is one of the challenging computational problems for both biomedical and data scientists. Most of the genome assemblers developed have used de Bruijn graph techniques. A de Bruijn graph represents a collection of read sequences by billions of vertices and edges, which require large amounts of memory and computational power to store and process. This is the major drawback to de Bruijn graph assembly. Massively parallel, multi-threaded, shared memory systems can be leveraged to overcome some of these issues. The objective of our research is to investigate the feasibility and scalability issues of de Bruijn graph assembly on Cray s Urika-GD system; Urika-GD is a high performance graph appliance with a large shared memory and massively multithreaded custom processor designed for executing SPARQL queries over large-scale RDF data sets. However, to the best of our knowledge, there is no research on representing a de Bruijn graph as an RDF graph or finding Eulerian paths in RDF graphs using SPARQL for potential genome discovery. In this paper, we address the issues involved in representing a de Bruin graphs as RDF graphs and propose an iterative querying approach for finding Eulerian paths in large RDF graphs. We evaluate the performance of our implementation on real world ebola genome datasets and illustrate how genome assembly can be accomplished with Urika-GD using iterative SPARQL queries.

It is an open question whether the chromatic number of $t$-perfect graphs is bounded by a constant. The largest known value for this parameter is 4, and the only example of a 4-critical $t$-perfect graph, due to Laurent and Seymour, is the complement of the line graph of the prism $\\Pi$ (a graph is 4-critical if it has chromatic number 4 and all its proper induced subgraphs are 3-colorable).

Local adjacency metric dimension of sun graph and stacked book graph

Science.gov (United States)

Yulisda Badri, Alifiah; Darmaji

2018-03-01

A graph is a mathematical system consisting of a non-empty set of nodes and a set of empty sides. One of the topics to be studied in graph theory is the metric dimension. Application in the metric dimension is the navigation robot system on a path. Robot moves from one vertex to another vertex in the field by minimizing the errors that occur in translating the instructions (code) obtained from the vertices of that location. To move the robot must give different instructions (code). In order for the robot to move efficiently, the robot must be fast to translate the code of the nodes of the location it passes. so that the location vertex has a minimum distance. However, if the robot must move with the vertex location on a very large field, so the robot can not detect because the distance is too far.[6] In this case, the robot can determine its position by utilizing location vertices based on adjacency. The problem is to find the minimum cardinality of the required location vertex, and where to put, so that the robot can determine its location. The solution to this problem is the dimension of adjacency metric and adjacency metric bases. Rodrguez-Velzquez and Fernau combine the adjacency metric dimensions with local metric dimensions, thus becoming the local adjacency metric dimension. In the local adjacency metric dimension each vertex in the graph may have the same adjacency representation as the terms of the vertices. To obtain the local metric dimension of values in the graph of the Sun and the stacked book graph is used the construction method by considering the representation of each adjacent vertex of the graph.

Aesthetic genital surgery seems to have become a fashionable issue nowadays. Many procedures and techniques have been described these last years, but very few long-term results or follow up studies are available. The novelty of this aspect of plastic surgery and the lack of evidence-based interventions, have led to a comparison with female genital mutilation. In this article, the authors provide an overview of the possible surgical procedures as well as the general principles of aesthetic sur...

Appearance of the male genitalia is linked with self-esteem and sexual identity. Aesthetic surgery of the male genitalia serves to correct perceived deficiencies as well as physical deformities, which may cause psychological distress. Attention to patient motivation for surgery and to surgical technique is key to achieving optimal results. In this review, the authors describe aesthetic surgical techniques for treatment of penile and scrotal deficiencies. They also discuss techniques for revision in patients with previous surgery.

Hospitalization and aesthetic health in older adults.

Science.gov (United States)

Moss, Hilary; Donnellan, Claire; O'Neill, Desmond

2015-02-01

To assess the impact of hospitalization on arts engagement among older people; and to assess perceptions of whether hospitals are aesthetically deprived environments. A Survey of Aesthetic and Cultural Health was developed to explore the role of aesthetics before, during and after hospital. Study participants were n = 150 hospital in-patients aged >65. Descriptive and inferential statistics were used to analyze the data. Attendance at arts events was an important part of life for this sample and a large drop off was noted in continuation of these activities in the year post-hospital stay. Physical health issues were the main causes but also loss of confidence and transport issues. Film, dance, and music were the most popular arts for this sample prior to hospital stay. Noise pollution caused by other patients, lack of control over TV/radio, and access to receptive arts in hospital (reading and listening to music) were important issues for patients in hospital. This study identifies a trend for decreasing exposure to arts beginning with a hospital stay and concludes that older people may need encouragement to resume engagement in arts following a hospital stay. There is relatively limited evidence regarding the nature of, and potential benefit from, aesthetics in healthcare and limited studies with rigorous methodology, and further research is needed to understand the aesthetic preferences of older people in hospital.

In order to realise this, a new understanding of the concept of aesthetics as a reflexive framing of performative choice...... by an evolutionary model based on Niklas Luhmann's systems theory: when the concept of art changes, the concept of aesthetics also changes.

Aesthetic concepts, perceptual learning, and linguistic enculturation: considerations from Wittgenstein, language, and music.

Science.gov (United States)

Croom, Adam M

2012-03-01

Aesthetic non-cognitivists deny that aesthetic statements express genuinely aesthetic beliefs and instead hold that they work primarily to express something non-cognitive, such as attitudes of approval or disapproval, or desire. Non-cognitivists deny that aesthetic statements express aesthetic beliefs because they deny that there are aesthetic features in the world for aesthetic beliefs to represent. Their assumption, shared by scientists and theorists of mind alike, was that language-users possess cognitive mechanisms with which to objectively grasp abstract rules fixed independently of human responses, and that cognizers are thereby capable of grasping rules for the correct application of aesthetic concepts without relying on evaluation or enculturation. However, in this article I use Wittgenstein's rule-following considerations to argue that psychological theories grounded upon this so-called objective model of rule-following fail to adequately account for concept acquisition and mastery. I argue that this is because linguistic enculturation, and the perceptual learning that's often involved, influences and enables the mastery of aesthetic concepts. I argue that part of what's involved in speaking aesthetically is to belong to a cultural practice of making sense of things aesthetically, and that it's within a socio-linguistic community, and that community's practices, that such aesthetic sense can be made intelligible.

With the growing use of personal and ubiquitous computing technology, an increase is seen in utilizing aesthetic aspects for designing interactive systems. The use of aesthetic interpretations, however, has differed in different applications, often lacking a coherent and holistic meaning of aesthetics. In this paper we provide an account on aesthetics, utilizing the pragmatist perspective, which can be used as a framework to design for aesthetic experience in interactive systems. We discuss s...

Expert interpretation of bar and line graphs: The role of graphicacy in reducing the effect of graph format.

Directory of Open Access Journals (Sweden)

David ePeebles

2015-10-01

Full Text Available The distinction between informational and computational equivalence of representations, first articulated by Larkin and Simon (1987 has been a fundamental principle in the analysis of diagrammatic reasoning which has been supported empirically on numerous occasions. We present an experiment that investigates this principle in relation to the performance of expert graph users of 2 x 2 'interaction' bar and line graphs. The study sought to determine whether expert interpretation is affected by graph format in the same way that novice interpretations are. The findings revealed that, unlike novices - and contrary to the assumptions of several graph comprehension models - experts' performance was the same for both graph formats, with their interpretation of bar graphs being no worse than that for line graphs. We discuss the implications of the study for guidelines for presenting such data and for models of expert graph comprehension.

Spatial modelling of landscape aesthetic potential in urban-rural fringes.

Science.gov (United States)

Sahraoui, Yohan; Clauzel, Céline; Foltête, Jean-Christophe

2016-10-01

The aesthetic potential of landscape has to be modelled to provide tools for land-use planning. This involves identifying landscape attributes and revealing individuals' landscape preferences. Landscape aesthetic judgments of individuals (n = 1420) were studied by means of a photo-based survey. A set of landscape visibility metrics was created to measure landscape composition and configuration in each photograph using spatial data. These metrics were used as explanatory variables in multiple linear regressions to explain aesthetic judgments. We demonstrate that landscape aesthetic judgments may be synthesized in three consensus groups. The statistical results obtained show that landscape visibility metrics have good explanatory power. Ultimately, we propose a spatial modelling of landscape aesthetic potential based on these results combined with systematic computation of visibility metrics. Copyright © 2016 Elsevier Ltd.

Interactive Graph Layout of a Million Nodes

Directory of Open Access Journals (Sweden)

Peng Mi

2016-12-01

Full Text Available Sensemaking of large graphs, specifically those with millions of nodes, is a crucial task in many fields. Automatic graph layout algorithms, augmented with real-time human-in-the-loop interaction, can potentially support sensemaking of large graphs. However, designing interactive algorithms to achieve this is challenging. In this paper, we tackle the scalability problem of interactive layout of large graphs, and contribute a new GPU-based force-directed layout algorithm that exploits graph topology. This algorithm can interactively layout graphs with millions of nodes, and support real-time interaction to explore alternative graph layouts. Users can directly manipulate the layout of vertices in a force-directed fashion. The complexity of traditional repulsive force computation is reduced by approximating calculations based on the hierarchical structure of multi-level clustered graphs. We evaluate the algorithm performance, and demonstrate human-in-the-loop layout in two sensemaking case studies. Moreover, we summarize lessons learned for designing interactive large graph layout algorithms on the GPU.

Parotidectomy for benign parotid tumors: An aesthetic approach

International Nuclear Information System (INIS)

Amin, A.; Mostafa, A.; Rifaat, M.; Shallan, M.; Rabie, A.; Elzohairy, M.; Nabawi, A.

2011-01-01

The sternocleidomastoid (SCM) partial thickness muscle flap is among the various methods described to correct parotidectomy defects, but its indications and limitations are not clearly demonstrated in several reports. This study was done to test the aesthetic outcome of this method, its indications and limitations. The technique was combined with a face lift incision to further improve the outcome. Patients and methods: At the National Cancer Institute, Cairo University, Egypt, 23 patients presenting with benign tumors underwent parotidectomy, 19 had superficial parotidectomy and four had total parotidectomy done. The superiorly based (SCM) muscle flap was used to correct the contour deformity. The aesthetic result was evaluated by assessing arid scoring the overall appearance of the scar, the degree of symmetry of the reconstructed parotid region and the site of the donor muscle to their contralateral normal sides. The overall aesthetic appearance was then calculated by the summation of the scores of the latter three parameters. Patients' satisfaction was assessed by patients' questionnaire. Result: The overall aesthetic appearance was good in 17 patients, and moderate in six patients. 16/23 patients had an overall deep satisfaction with the result. The residual hollowness of the parotid following reconstruction of the total parotidectomy defect and the poor quality of scars were the main reasons affecting the aesthetic outcome. Conclusion: Superficial parotidectomy through facelift incision with immediate reconstruction with superiorly based partial thickness SCM flap allows adequate resection of most benign parotid tumors with a satisfactory aesthetic outcome and minimal donor site morbidity

The two volumes comprising Part 1 of this work embrace the theme of Eulerian trails and covering walks. They should appeal both to researchers and students, as they contain enough material for an undergraduate or graduate graph theory course which emphasizes Eulerian graphs, and thus can be read by any mathematician not yet familiar with graph theory. But they are also of interest to researchers in graph theory because they contain many recent results, some of which are only partial solutions to more general problems.

The One Universal Graph — a free and open graph database

Science.gov (United States)

Ng, Liang S.; Champion, Corbin

2016-02-01

Recent developments in graph database mostly are huge projects involving big organizations, big operations and big capital, as the name Big Data attests. We proposed the concept of One Universal Graph (OUG) which states that all observable and known objects and concepts (physical, conceptual or digitally represented) can be connected with only one single graph; furthermore the OUG can be implemented with a very simple text file format with free software, capable of being executed on Android or smaller devices. As such the One Universal Graph Data Exchange (GOUDEX) modules can potentially be installed on hundreds of millions of Android devices and Intel compatible computers shipped annually. Coupled with its open nature and ability to connect to existing leading search engines and databases currently in operation, GOUDEX has the potential to become the largest and a better interface for users and programmers to interact with the data on the Internet. With a Web User Interface for users to use and program in native Linux environment, Free Crowdware implemented in GOUDEX can help inexperienced users learn programming with better organized documentation for free software, and is able to manage programmer's contribution down to a single line of code or a single variable in software projects. It can become the first practically realizable “Internet brain” on which a global artificial intelligence system can be implemented. Being practically free and open, One Universal Graph can have significant applications in robotics, artificial intelligence as well as social networks.

Should advertising by aesthetic surgeons be permitted?

Directory of Open Access Journals (Sweden)

Neeraj Nagpal

2017-01-01

Full Text Available Cosmetic, aesthetic and cutaneous surgical procedures require qualified specialists trained in the various procedures and competent to handle complications. However, it also requires huge investments in terms of infrastructure, trained staff and equipment. To be viable advertising is essential to any establishment which provides cosmetic and aesthetic procedures. Business men with deep pockets establish beauty chains which also provide these services and advertise heavily to sway public opinion in their favour. However, these saloons and spas lack basic medical facilities in terms of staff or equipment to handle any complication or medical emergency. To have a level playing field ethical advertising should be permitted to qualified aesthetic surgeons as is permitted in the US and UK by their respective organisations.

Degree-based graph construction

International Nuclear Information System (INIS)

Kim, Hyunju; Toroczkai, Zoltan; Erdos, Peter L; Miklos, Istvan; Szekely, Laszlo A

2009-01-01

Degree-based graph construction is a ubiquitous problem in network modelling (Newman et al 2006 The Structure and Dynamics of Networks (Princeton Studies in Complexity) (Princeton, NJ: Princeton University Press), Boccaletti et al 2006 Phys. Rep. 424 175), ranging from social sciences to chemical compounds and biochemical reaction networks in the cell. This problem includes existence, enumeration, exhaustive construction and sampling questions with aspects that are still open today. Here we give necessary and sufficient conditions for a sequence of nonnegative integers to be realized as a simple graph's degree sequence, such that a given (but otherwise arbitrary) set of connections from an arbitrarily given node is avoided. We then use this result to present a swap-free algorithm that builds all simple graphs realizing a given degree sequence. In a wider context, we show that our result provides a greedy construction method to build all the f-factor subgraphs (Tutte 1952 Can. J. Math. 4 314) embedded within K n setmn S k , where K n is the complete graph and S k is a star graph centred on one of the nodes. (fast track communication)

Downhill Domination in Graphs

Directory of Open Access Journals (Sweden)

Haynes Teresa W.

2014-08-01

Full Text Available A path π = (v1, v2, . . . , vk+1 in a graph G = (V,E is a downhill path if for every i, 1 ≤ i ≤ k, deg(vi ≥ deg(vi+1, where deg(vi denotes the degree of vertex vi ∈ V. The downhill domination number equals the minimum cardinality of a set S ⊆ V having the property that every vertex v ∈ V lies on a downhill path originating from some vertex in S. We investigate downhill domination numbers of graphs and give upper bounds. In particular, we show that the downhill domination number of a graph is at most half its order, and that the downhill domination number of a tree is at most one third its order. We characterize the graphs obtaining each of these bounds

Subsampling for graph power spectrum estimation

KAUST Repository

Chepuri, Sundeep Prabhakar; Leus, Geert

2016-01-01

In this paper we focus on subsampling stationary random signals that reside on the vertices of undirected graphs. Second-order stationary graph signals are obtained by filtering white noise and they admit a well-defined power spectrum. Estimating the graph power spectrum forms a central component of stationary graph signal processing and related inference tasks. We show that by sampling a significantly smaller subset of vertices and using simple least squares, we can reconstruct the power spectrum of the graph signal from the subsampled observations, without any spectral priors. In addition, a near-optimal greedy algorithm is developed to design the subsampling scheme.

We consider modular graph functions that arise in the low energy expansion of the four graviton amplitude in type II string theory. The vertices of these graphs are the positions of insertions of vertex operators on the toroidal worldsheet, while the links are the scalar Green functions connecting the vertices. Graphs with four and five links satisfy several non-trivial relations, which have been proved recently. We prove these relations by using elementary properties of Green functions and the details of the graphs. We also prove a relation between modular graph functions with six links. (paper)

2015-01-01

The paper presents the cases of five patients who developed complications after aesthetic medicine procedures. Four of the cases involved women who reported to the Department of Forensic Medicine, Medical University of Lodz, for a description and legal qualification of bodily injuries suffered as a result of aesthetic medicine procedures, whereas one was related to the assessment of accuracy of medical management at the request of the prosecutor handling the case. The reported cases concerned acid exfoliation treatments, photoepilation and cryotherapy. The authors attempt to discuss the most common complications that may occur after aesthetic medicine procedures, and measures to avoid them.

Semantic graphs and associative memories

Science.gov (United States)

Pomi, Andrés; Mizraji, Eduardo

2004-12-01

Graphs have been increasingly utilized in the characterization of complex networks from diverse origins, including different kinds of semantic networks. Human memories are associative and are known to support complex semantic nets; these nets are represented by graphs. However, it is not known how the brain can sustain these semantic graphs. The vision of cognitive brain activities, shown by modern functional imaging techniques, assigns renewed value to classical distributed associative memory models. Here we show that these neural network models, also known as correlation matrix memories, naturally support a graph representation of the stored semantic structure. We demonstrate that the adjacency matrix of this graph of associations is just the memory coded with the standard basis of the concept vector space, and that the spectrum of the graph is a code invariant of the memory. As long as the assumptions of the model remain valid this result provides a practical method to predict and modify the evolution of the cognitive dynamics. Also, it could provide us with a way to comprehend how individual brains that map the external reality, almost surely with different particular vector representations, are nevertheless able to communicate and share a common knowledge of the world. We finish presenting adaptive association graphs, an extension of the model that makes use of the tensor product, which provides a solution to the known problem of branching in semantic nets.

RNA graph partitioning for the discovery of RNA modularity: a novel application of graph partition algorithm to biology.

Directory of Open Access Journals (Sweden)

Namhee Kim

Full Text Available Graph representations have been widely used to analyze and design various economic, social, military, political, and biological networks. In systems biology, networks of cells and organs are useful for understanding disease and medical treatments and, in structural biology, structures of molecules can be described, including RNA structures. In our RNA-As-Graphs (RAG framework, we represent RNA structures as tree graphs by translating unpaired regions into vertices and helices into edges. Here we explore the modularity of RNA structures by applying graph partitioning known in graph theory to divide an RNA graph into subgraphs. To our knowledge, this is the first application of graph partitioning to biology, and the results suggest a systematic approach for modular design in general. The graph partitioning algorithms utilize mathematical properties of the Laplacian eigenvector (µ2 corresponding to the second eigenvalues (λ2 associated with the topology matrix defining the graph: λ2 describes the overall topology, and the sum of µ2's components is zero. The three types of algorithms, termed median, sign, and gap cuts, divide a graph by determining nodes of cut by median, zero, and largest gap of µ2's components, respectively. We apply these algorithms to 45 graphs corresponding to all solved RNA structures up through 11 vertices (∼ 220 nucleotides. While we observe that the median cut divides a graph into two similar-sized subgraphs, the sign and gap cuts partition a graph into two topologically-distinct subgraphs. We find that the gap cut produces the best biologically-relevant partitioning for RNA because it divides RNAs at less stable connections while maintaining junctions intact. The iterative gap cuts suggest basic modules and assembly protocols to design large RNA structures. Our graph substructuring thus suggests a systematic approach to explore the modularity of biological networks. In our applications to RNA structures, subgraphs

Aesthetic practitioner as a physician and businessperson – Is it achievable?

Directory of Open Access Journals (Sweden)

Elena Thomaidou

2018-04-01

Full Text Available Aesthetic medicine subspecialty is no longer limited to the fields of plastic surgery and dermatology, as many specialties are offering aesthetic medical procedures to better accommodate their patients’ aesthetic needs. During the last decade there is an enormous increase of cosmetic treatments worldwide and the absence of regulations in aesthetic practice has become more noticeable. This article illustrates the challenges that every aesthetic physician must overcome daily to maintain high ethos and make decisions according to patient’s best interest and safety. Aesthetic practitioner should be more than a businessperson with a medical degree. If they place their integrity and moral standards to the test, then they will continue to be judged by their colleagues and society. Is it possible to maintain the same moral obligations during cosmetic procedures as with any other medical treatments?

2018-02-01

Full Text Available The teaching aim of Mechanical Drawing is to cultivate the students' graphics interpreting ability, plotting ability, inter-space imagination and innovation ability. For engineering students in China Universities, Mechanical Drawing course with the characteristics of 3D and 2D inter-space transformation, is often difficult to master. The ordinary dull teaching method is not enough for stimulating students’ spatial imagination capability, interest in learning, and cannot meet teachers’ teaching needs to explain complicated graphs relationships. In this paper, we design an interactive teaching system based on mobile augmented reality to improve the learning efficiency of Mechanical Drawing course. To check the effect of the proposed system, we carried out a case study of course teaching of Mechanical Drawing. The results demonstrate that the class for which interactive teaching system based on mobile augmented reality technology was adopted is significantly superior to the class for which the ordinary dull teaching approach was adopted with regard to the degree of proficiency of course key and difficult points content，spatial imagination capability, students’ interest in learning and study after class, especially in respect of students’ learning interest and spatial imagination capability.

2015-08-01

In recent years, a plethora of novel therapeutic approaches to fight signs of aging and to influence external body appearance have become available in aesthetic dermatology. Extensive research in this field has led to advanced understanding of the anatomy and physiology of the aging face. To successfully address the complex age-related alterations anti-aging treatment nowadays calls for a multi-faceted approach. Most frequently utilized aesthetic procedures include the use of botulinum toxin, a variety of filling substances, microneedling (collagen induction therapy), chemical peeling, lasers, radiofrequency, thread facelift and injectional lipolysis with phosphatidylcholine/deoxycholate among others. Unfortunately, many clinicians still lack in-depth understanding of potential complications, risk factors and side effects associated with minimal-invasive procedures. The following review aims to give a broad overview of nowadays most frequently used approaches in the dermato-aesthetic field and their related complications. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

Social aesthetics and the management of addiction.

Science.gov (United States)

Musalek, Michael

2010-11-01

One of the main causes of nonadherence is that the goals and forms of addiction treatment are not sufficiently attractive. To study the attractiveness of treatment in clinical practice inevitably means to enter the field of social aesthetics. The call for the implementation of social aesthetics in practice results in a shift of paradigms in the treatment of patients suffering from dependence syndromes. The main themes in the literature covered by the article focus on the role of social aesthetics in medicine in general, as well as on the attractiveness of addiction treatment, in particular. When treatment objectives and programmes become more attractive the result will be reduced drop-out rates, and in turn an increase of treatment effectiveness. Transferring theory of social aesthetics to clinical practice, the Anton Proksch Institute's Orpheus Programme is concerned with opening up spaces and creating atmospheres in which it becomes possible for the individual addicts to realise their possibilities. The challenge in the therapeutic process is not only to recognise the significance of the disorders' pathology but also to find ways out of the imagined impossibilities by opening up new possibilities and uncovering resources of the suffering human.

Sánchez-Camus, Roberto

2009-12-01

The Problem of Application investigates the multiple viewpoints in defining a critical aesthetic in applied arts practice. Amongst organisations, participants, and facilitators there are varying wants and needs in any creative project with an educational agenda. The product of arts based health initiatives often seek to inform and educate, whereby an aesthetic standard may seem contrary to this participatory approach. This research maintains that an aesthetic approach is a lively portion of the collaborative dialogue, which requires interrogation and consideration for a successful outcome. Through the analysis of a participatory arts project completed in West Africa addressing youth issues and HIV/AIDS, The Problem of Application seeks to uncover the multiple facets surrounding the defining of aesthetics in applied practice. The project entitled Youth Visions: Transforming our Futures Together worked with students aged 17-21 to develop an outdoor mural and a live performance inspired by the traditions of local festivals. With an anthropological approach to aesthetic criticism, Youth Visions revealed the multiple layers that define our focus of appreciation.

Ontological-epistemological views of the beautiful Byzantine aesthetics

2015-01-01

Full Text Available The paper approaches the ontological-epistemology aspects of the beauty of Byzantine art. Byzantine aesthetics and Byzantine art are unjustly neglected in the history of aesthetic thought. Christian aestheticians have an ambivalent attitude towards art. Because, Byzantine painting represents reality show based on the Christians view, where absolutizs a new dimension of spirituality and aesthetics deriving from the ontological-epistemological positions. The phenomenon of beauty in Byzantine art is primarily deposited in epistemological components, where everything is directed to the knowledge of the truth. In Byzantine art beauty has, above all, spiritual character; it does not have a classical aesthetic dimension, but primarily because the ontological character is recognized as one of the innumerable divine energies and of phenomena. The Byzantine painter makes an effort to realize the creative transformation of matter into a unique experience community and relationship with God, who volatility of the world beyond the ontological light that is converted from non-being into being.

A review of the evidence supporting the aesthetic orthodontic treatment need indices.

Science.gov (United States)

Borzabadi-Farahani, Ali

2012-11-01

Aesthetic improvement and psychological enhancement have been cited as justifications for orthodontic treatment. This paper reviews the evidence that relates malocclusion to psychological health and quality of life and explores whether this evidence supports the most commonly used aesthetic Orthodontic Treatment Need Indices (OTNI). The relevant cited material from the MEDLINE, Web of Science, Scopus, Cochrane databases, and scientific textbooks were used. The citation rate was confirmed by using the Google Scholar. The subjective nature of aesthetic indices and the variable perception of attractiveness between clinicians and patients, and among various cultures or countries are a few limitations of aesthetic OTNI. The available evidence of mainly cross-sectional studies on the link between malocclusion and either psychosocial well-being or quality of life is not conclusive, and sometimes contradictory, to suggest these characteristics are affected by malocclusions. Further, the long-term longitudinal studies did not suggest that people with malocclusion are disadvantaged psychologically, or their quality of life would be worse off, which challenges using aesthetic OTNI to assess the social and psychological implications of malocclusion. The subjective nature of aesthetic OTNI and the minor contributory role of malocclusion in psychosocial health or quality of life undermine using aesthetic indices to assess the likely social and psychological implications of malocclusion. Consequently, using aesthetic OTNI, as a method to quantify malocclusion remains open to debate. Various soft and hard-tissue analyses are used before formulating a treatment plan (i.e., assessment of sagittal and vertical skeletal relationships). The addition of a shortened version of these analyses to the aesthetic OTNI can be a good substitute for the aesthetic components of OTNI, if an assessment of the aesthetic aspects of malocclusion is intended. This reduces subjectivity and improves the

Commuting graphs of matrix algebras

International Nuclear Information System (INIS)

Akbari, S.; Bidkhori, H.; Mohammadian, A.

2006-08-01

The commuting graph of a ring R, denoted by Γ(R), is a graph whose vertices are all non- central elements of R and two distinct vertices x and y are adjacent if and only if xy = yx. The commuting graph of a group G, denoted by Γ(G), is similarly defined. In this paper we investigate some graph theoretic properties of Γ(M n (F)), where F is a field and n ≥ 2. Also we study the commuting graphs of some classical groups such as GL n (F) and SL n (F). We show that Γ(M n (F)) is a connected graph if and only if every field extension of F of degree n contains a proper intermediate field. We prove that apart from finitely many fields, a similar result is true for Γ(GL n (F)) and Γ(SL n (F)). Also we show that for two fields E and F and integers m, n ≥> 2, if Γ(M m (E)) ≅ Γ(M n (F)), then m = n and vertical bar E vertical bar = vertical bar F vertical bar. (author)

In this paper, we investigate continuous-time quantum walk on star graphs. It is shown that quantum central limit theorem for a continuous-time quantum walk on star graphs for N-fold star power graph, which are invariant under the quantum component of adjacency matrix, converges to continuous-time quantum walk on K 2 graphs (complete graph with two vertices) and the probability of observing walk tends to the uniform distribution.

Artworks with sad and affectively negative content have repeatedly been reported to elicit positive aesthetic appreciation. This topic has received much attention both in the history of poetics and aesthetics as well as in recent studies on sad films and sad music. However, poetry and aesthetic evaluations of joyful and sad poetry have received only little attention in empirical studies to date. We collected beauty and liking ratings for 24 sad and 24 joyful poems from 128 participants. Following previous studies, we computed an integrated measure for overall aesthetic appreciation based on the beauty and liking ratings to test for differences in appreciation between joyful and sad poems. Further, we tested whether readers' judgments are related to their affinity for poetry. Results show that sad poems are rated significantly higher for aesthetic appreciation than joyful poems, and that aesthetic appreciation is influenced by the participants' affinity for poetry.

Tailored graph ensembles are a developing bridge between biological networks and statistical mechanics. The aim is to use this concept to generate a suite of rigorous tools that can be used to quantify and compare the topology of cellular signalling networks, such as protein-protein interaction networks and gene regulation networks. We calculate exact and explicit formulae for the leading orders in the system size of the Shannon entropies of random graph ensembles constrained with degree distribution and degree-degree correlation. We also construct an ergodic detailed balance Markov chain with non-trivial acceptance probabilities which converges to a strictly uniform measure and is based on edge swaps that conserve all degrees. The acceptance probabilities can be generalized to define Markov chains that target any alternative desired measure on the space of directed or undirected graphs, in order to generate graphs with more sophisticated topological features.

The Smallest Valid Extension-Based Efficient, Rare Graph Pattern Mining, Considering Length-Decreasing Support Constraints and Symmetry Characteristics of Graphs

Full Text Available Frequent graph mining has been proposed to find interesting patterns (i.e., frequent sub-graphs from databases composed of graph transaction data, which can effectively express complex and large data in the real world. In addition, various applications for graph mining have been suggested. Traditional graph pattern mining methods use a single minimum support threshold factor in order to check whether or not mined patterns are interesting. However, it is not a sufficient factor that can consider valuable characteristics of graphs such as graph sizes and features of graph elements. That is, previous methods cannot consider such important characteristics in their mining operations since they only use a fixed minimum support threshold in the mining process. For this reason, in this paper, we propose a novel graph mining algorithm that can consider various multiple, minimum support constraints according to the types of graph elements and changeable minimum support conditions, depending on lengths of graph patterns. In addition, the proposed algorithm performs in mining operations more efficiently because it can minimize duplicated operations and computational overheads by considering symmetry features of graphs. Experimental results provided in this paper demonstrate that the proposed algorithm outperforms previous mining approaches in terms of pattern generation, runtime and memory usage.
