Formation and Evolution of Chromitites in the Hongshishan Complex,Beishan Orogenic Collage,NW China:Constraints from Mineralogical Compositions,Re-Os Isotopes and Platinum-Group Element Geochemistry

The Hongshishan chromitite deposits are situated to the north of the Beishan orogenic collage,in the southern part of the Central Asian Orogenic Belt.This study describes the mineral chemistry,Re-Os isotopes and platinum-group elements geochemistry of the Hongshishan chromitites for the purpose of constraining the origin,evolution and composition of their parental melts.The restricted ranges of Al_(2)O_(3),Cr_(2)O_(3)and Cr#-Mg#variation of chromite-cores and chromites fall within the field of the mid-ocean ridge and ophiolitic podiform chromite settings.The(^(187)Os/^(188)Os)i ratios of the chromitites are in the range of 0.12449–0.12745(average 0.12637)and theγOs are from-1.92 to-0.06(average-0.83).In the Re-Os isotope diagrams,all the samples fall in the field of chromitites and show a residual peridotitic trend.The range of Os isotopic compositions andγOs values indicate that they overlap the depleted MORB mantle(DMM)as well as being close to global Os isotopic data andγOs of ophiolite chromitites.The characteristics of the PGE contents can be roughly subdivided into two groups:podiform chromitites and Ural-Alaskan type complexes.For the ferritchromite cores,the calculated Al_(2)O_(3)concentrations of the parental melt are higher(average 16.65 wt%)in high-Cr than high-Al chromitite(average 16.17 wt%)and for the chromite,the calculated Al_(2)O_(3)concentrations are even higher(average 16.48 wt%)in the high-Cr than the high-Al examples(average 15.38 wt%).In the(TiO_(2))melt vs.TiO_(2)diagrams,most high-Al melts fall in the MORB,while the high-Cr melts fall in the ARC field.The calculated Fe O/Mg O ratios for the parental melt show the closest resemblance to a MORB magma composition.The inferred parental melt composition for studied chromitites falls in the field of mid-ocean ridge basalt(MORB)magmas and far away from boninite.The calculated degrees of partial melting producing the chromitites are 16%-22%(average 19%),which is around the range of those of the MORB magmas.The chromitites are suggested to have been formed in a MORB setting.The chromites and ferritchromite cores are mostly scattered along the MORB and SSZ harzburgite–dunite fields.Ferritchromite rims and ferritchromites with high YFes formed as a result of alteration during serpentinization..

Creating Space for Children’s Voices: Utility of the Collage Life Story Elicitation Technique

A challenge for many School-Based Family Counseling(SBFC)practitioners,child psychotherapists and researchers are finding ways to give voice to children and eliciting trustworthy and detailed narratives that could serve as resource for understanding the needs of young clients in the context of all their interpersonal networks.Children are often reticent when asked to self-disclose and tell their stories during consultation.The purpose of the present study was to examine the utility of five sequential steps constituting the Collage Life Story Elicitation Technique(CLET)for scaffolding storytelling among children in middle childhood(aged 9-12 years).Using the CLET for data collection and conducting an interpretive analysis,the researchers explored the performance of 38 middle-childhood children living in three different settings.Findings suggest that the five sequential steps of the CLET adequately and satisfactorily combine to stimulate and elicit rich data and help children to construct their narratives and represent the challenges they face in everyday living.We discuss the application of CLET in SBFC practice as tool when screening and intervention planning for children’s perspectives pertaining to a range of topics regarding each of the four quadrants as proposed in the SBFC metamodel.

A Fractal Compression Algorithm Based on Collage Distance Estimating and Compensating

A new fractal image compression scheme based on collage distance is explained, which can provide of the scheme two different compression codes containing their own unique collage distance sets and different types of similar transforms. The analysis and applications of the scheme indicate that it can be adopted as a suitable alternative for balancing between the distortion measure and compression ratio occurring in ordinary fractal compression method.

Manufacturable pattern collage along a boundary

Recent years have shown rapid development of digital fabrication techniques, making manufacturing individual models reachable for ordinary users. Thus,tools for designing customized objects in a user-friendly way are in high demand. In this paper, we tackle the problem of generating a collage of patterns along a given boundary, aimed at digital fabrication. We represent the packing space by a pipe-like closed shape along the boundary and use ellipses as packing elements for computing an initial layout of the patterns. Then we search for the best matching pattern for each ellipse and construct the initial pattern collage in an automatic manner. To facilitate editing the collage, we provide interactive operations which allow the user to adjust the layout at the coarse level. The patterns are fine-tuned based on a spring–mass system after each interaction step. After this interactive process, the collage result is further optimized to enforce connectivity. Finally, we perform structural analysis on the collage and enhance its stability, so that the result can be fabricated. To demonstrate the effectiveness of our method, we show results fabricated by 3D printing and laser cutting.

Visual perception driven collage synthesis

A collage is a composite artwork made from the spatial layout of multiple pictures on a canvas,collected from the Internet or user photographs.Collages,usually made by skilled artists,involve a complex manual process,especially when searching for component pictures and adjusting their spatial layout to meet artistic requirements.In this paper,we present a visual perception driven method for automatically synthesizing visually pleasing collages.Unlike previous works,we focus on how to design a collage layout which not only provides easy access to the theme of the overall image,but also conforms to human visual perception.To achieve this goal,we formulate the generation of collages as a mapping problem:given a canvas image,first,compute a saliency map for it and a vector field for each sub-region of it.Second,using a divide-and-conquer strategy,generate a series of patch sets from the canvas image,where the salient map and the vector field are used to determine each patch’s size and direction respectively.Third,construct a Gestalt-based energy function to choose the most visually pleasing and orderly patch set as the final layout.Finally,using a semantic-color metric,map the picture set to the patch set to generate the final collage.Extensive experimental and user study results show that this method can generate visual pleasing collages.

Non-dominated sorting based multi-page photo collage

The development of social networking services(SNSs)revealed a surge in image sharing.The sharing mode of multi-page photo collage(MPC),which posts several image collages at a time,can often be observed on many social network platforms,which enables uploading images and arrangement in a logical order.This study focuses on the construction of MPC for an image collection and its formulation as an issue of joint optimization,which involves not only the arrangement in a single collage but also the arrangement among different collages.Novel balance-aware measurements,which merge graphic features and psychological achievements,are introduced.Non-dominated sorting genetic algorithm is adopted to optimize the MPC guided by the measurements.Experiments demonstrate that the proposed method can lead to diverse,visually pleasant,and logically clear MPC results,which are comparable to manually designed MPC results.

Prophetic Collage: Bella Li's Lost Lake

With an eye to the workings of collage-in particular its prophetic temporality-I explore the collage practice of the Australian poet Bella Li,with a focus on her second book,Lost Lake(2018).Taking my cue from movements of broken or disjunctive association in Li*s work,I seek to mirror Li’s poetic collages with a reading that is itself both exploratory and associative.Beginning by commenting on the circularity of collage,this article itself becomes a kind of collage.Li's surrealist practice,layering evocative object(word,image,idea)over evocative object,instigates a chain of associations.Via such sequences’ellipses and associative chains,Li writes poetry as transtemporal collage,as a surrealist dream,and as prophecy of what was and is and is yet to come.

Yanchuan Folk Art—Collage

Latest Triassic to Early Jurassic Thrusting and Exhumation in the Southern Ordos Basin, North China: Evidence from LA-ICP-MS-based Apatite Fission Track Thermochronology

The contractional structures in the southern Ordos Basin recorded critical evidence for the interaction between Ordos Basin and Qinling Orogenic Collage. In this study, we performed apatite fission track （AFT） thermochronology to unravel the timing of thrusting and exhumation for the Laolongshan-Shengrenqiao Fault （LSF） in the southern Ordos Basin. The AFT ages from opposite sides of the LSF reveal a significant latest Triassic to Early Jurassic time-temperature discontinuity across this structure. Thermal modeling reveals at the latest Triassic to Early Jurassic, a ~50~C difference in temperature between opposite sides of the LSF currently exposed at the surface. This discontinuity is best interpreted by an episode of thrusting and exhumation of the LSF with -1.7 km of net vertical displacement during the latest Triassic to Early Jurassic. These results, when combined with earlier thermochronological studies, stratigraphic contact relationship and tectono-sedimentary evolution, suggest that the southern Ordos Basin experienced coeval intense tectonic contraction and developed a north-vergent fold-and-thrust belt. Moreover, the southern Ordos Basin experienced a multi-stage differential exhumation during Mesozoic, including the latest Triassic to Early Jurassic and Late Jurassic to earliest Cretaceous thrust-driven exhumation as well as the Late Cretaceous overall exhumation. Specifically, the two thrust-driven exhumation events were related to tectonic stress propagation derived from the latest Triassic to Early Jurassic continued compression from Qinling Orogenic Collage and the Late Jurassic to earliest Cretaceous intracontinental orogeny of QinUng Orogenic Collage, respectively. By contrast, the Late Cretaceous overall exhumation event was related to the collision of an exotic terrain with the eastern margin of continental China at -100 Ma.

Books Becoming Museums:Exploring Intertextuality and Pictorial Influence in Susan Howe’s Debths

At the end of the seventies,science,philosophy and arts became a succulent material for poets,especially for those belonging to experimental groups like Susan Howe.Debths(2017),probably Howe’s last book,is a museum for any reader as it is not just an ensemble of memoirs and related poems,but also a source of pictorial and literary information.It includes extracts from 19th and 20th century texts(fairy tales,essays,and other genres)by her favorite influential authors as well as her ekphrastic poems that evocate paintings and sculptures from the Isabella Gardner Museum where she once found the inspiration.Even music has a place in this book,as Howe tends to include sound effects,interferences and references to musical pieces in her poems to make them multidimensional works of art.Along the pages,Howe highlights the materiality of writing,as well as the relevance of the form,especially in“Tom Tit Tot”,where she shows her mastery of the collage technique.All these carefully chosen pieces have the mission of representing the eternal return,the relativity of time,and how death can also be a beginning.

Memory and Aesthetics： Study of Musical Quotations in Ives’s and Crumb’s Music

Throughout Western music history, pre-existing material has long been the aesthetic core of a new composition. Yet there has never been such an epoch as our time in which using pre-existing material, melodic quotation in particular, features so extensively in works of many of the composers. The aim of this paper is to investigate how the use of quoted tunes in a musical piece operates in an interwoven complex where time and space are of the essence. A quote is able to oscillate perpetually between one’s mental worlds of the memorable past and the imaginative present when it is highlighted enough to be recognizable from its surrounding context. Upon interpreting the use of quotation in various contexts, the aesthetic object, I argue, is the shift from original to quoted music, and vice versa. And listeners can respond aesthetically to the quotation itself even without knowledge of its provenance and textual or referential content.

Covers and Contents:Why iot is a Marvelous Work of Art

iot(1924)was a remarkable artistic achievement.Following collages in the works of Picasso,Braque,and Gris,publisher Bill Bird created a collage of newspaper headlines on the cover of that slim volume that linked to the collage of vignettes within that Hemingway wrote.Both depicted a world losing traditional values,torn by war and despair and increasing commercialism.Subsequent Hemingway book covers by Scribners,at least until The Old Man and the Sea,emphasized sales over art and had little to do with content.

Theatrical Hybridity, Thy Name Is Conflict： A Case Study on Holo Taiwan Residents Opera Troupe＇s Tai Tzu Fu Chou （The Prince＇s Vengeful Plan）

Holo Taiwan Residents Opera Troupe has produced a series of intercultural performances in Taiwan Residents Opera since the troupe adapted Nikolai Vasilievich Gogol＇s （1809-1852） The Government Inspector in 1996. In fact, there is a huge controversy over these intercultural performances which fuse western drama with traditional Taiwan Residents performing art because such a kind of theatrical hybridity lacks the spirit of the original and damages the aesthetics of native performing art practice. In 2002, Holo adapted William Shakespeare＇s Hamlet into a six-hour-long performance, Tai Tzu Fu Chou （The Prince＇s Vengeful Plan）, which the troupe tried to explore new source for traditional Taiwan Residents Opera and expected to bring something new to Taiwan Residents audience. However, The Prince＇s Vengeful Plan is considered ＂cultural collage＂ as well as an unsuccessful intercultural performance. Besides, The Prince＇s Vengeful Plan is accused to blaspheme Shakespeare because the performance merely maintains the frame of the original and distorts the spirit of the original. According to Rustom Bharucha, the most problematic aspect of intercultural performance is ＂de-historicizing tendency＂, and such a condition explains why Holo＇s The Prince＇s Vengeful Plan cannot transcend the original. In order to detect the problems of intercultural adaptation in Holo＇s The Prince Vengeful Plan, we cover the related issues in three aspects： （1） to discuss the development of Taiwan Residents Opera in Taiwan; （2） to explore the cultural conflicts when the text of the source culture is adapted into the performance of the target culture; and （3） to see how and why the spirit and aesthetics of Shakespeare＇s verses in Hamlet are distorted in Holo＇s theatrical adaptation. After that, we expect to conclude the impossibility of adapting Shakespeare＇s play into traditional Taiwan Residents Opera in the case of Holo＇s The Prince＇s Vengeful Plan.
