The Broken Circle and Integration of Youthful Narrative Perspectives in Mainstream Media

That area of terror

New Jersey artist Robert Smithson reveled in sites untouched by civilization: ‘I like landscapes that suggest prehistory’, he told an interviewer in 1973, just before his tragic death. ‘I was always interested in origins and primordial beginnings’. Augur of ecological collapse, Smithson maintained a strange connection to Northern Europe. Broken Circle / Spiral Hill (1971) – now meekly dissolving in a sand pit outside of Emmen – survives as the artist’s most famous ‘land reclamation’ project and the sole earthwork he completed outside of the United States. The Drenthe piece stands as a harbinger of what the artist may have achieved with his – not unproblematic – fusion of culture and land management: ‘With my work in the quarry I somehow re-organized a disrupted situation’. Smithson wrote of Broken Circle, ‘Holland [sic] is (…) completely cultivated and so much an earthwork itself’. Broken Circle, for its sake, extended Smithson’s dismantling of the bordered, overtly retinal artwork. And this, vaguely Duchampian, notion extended to the work’s material ontology.

Multi-modal Analysis of Water Milk Consumption Preferences and Influencing Factors——Based on Shanghai's Generation Z Crowd

This study aims to analyze the consumption preference and influencing factors of Buffalo Milk among Shanghai's Generation Z population, to provide marketing strategy references for dairy companies, and to promote the healthy development of Shanghai's Buffalo Milk market.In this paper, we first take the Generation Z population as the main body through network survey and literature survey, and select potential consumers who will buy buffalo milk from them, and then recover the questionnaires to conduct follow-up surveys, organize and analyze the existing buffalo milk industry data, and derive the overall development of Shanghai's Generation Z buffalo milk market, and compare the customer's loyalty to the brand by using the retention index in order to explore the brand equity of each brand. The brand equity of each brand is explored by utilizing the retention index to compare customer loyalty. Secondly, we collect basic data on buffalo milk consumption of Generation Z through online questionnaire survey based on K-Means clustering algorithm for feature extraction, and use word cloud to draw user profiles to find out the consumption preference of buffalo milk crowd. Then, the logistic model is used to explore the significant influencing factors that affect consumers' purchase of buffalo milk. Finally, we provide reasonable and effective suggestions for the "broken circle" problem of buffalo milk.

Broken Circle: Exploring Indigenous Perspectives of Academic Integrity

Across the land now known as Canada, a growing body of research confirms the importance of academic integrity in higher education. Indigenous voices, though, are largely subsumed within the morass of dominant student and faculty perspectives or segregated alongside international student perspectives. Using the imagery of the Medicine Wheel as a framework, this session explores the views of Indigenous faculty, staff, administrators, and graduates affiliated with a mid-sized post-secondary institution in British Columbia. Findings from a small-scale research study reveal a holistic vision of academic integrity that emphasizes relationships with people and knowledge. As Wilson (2008) explains, “relationships do not merely shape reality, they are reality” (p.7). In this relational paradigm, academic integrity is inseparably grounded in the broader principles of integrity, and relies on reciprocal truth-telling to maintain the wholeness of the circle (Lindstrom, 2022). In this session, participants will gain insights into the ways dominant approaches to academic integrity can break the circle of integrity. The session will review similarities and differences between the experiences of Indigenous and non-Indigenous learners, and will consider how Indigenous views of relationality may foster a culture where stewardship of knowledge strengthens the bonds of integrity for all.

Analysis of the Transformation of Bilibili Video Content from the Perspective of Communication

In today's extremely developed Internet, Bilibili has changed from a niche website to a mainstream media. This paper takes the content transformation in the transformation process of Bilibili as the main research object. It analyzes the content partition change, user growth and "broken circle" publicity according to the content partition data, form change and user portrait in its transformation and development. The results show that the content of Bilibili has gradually become mainstream and ubiquitous. Among them, Generation Z users still occupy a high proportion of users, and Bilibili also makes good use of this user’s feature. The New Year party, live broadcast business and homemade programs have achieved remarkable results. At the same time, during the transformation of Bilibili, problems such as high-profit pressure, reduced user stickiness, and difficulty in supervising the infringement of secondary creative content also emerged. Taking Bilibili as the research object, the research on its transformation from a single-style video website to a social media has reference significance for other domestic video websites.

Two New Species of Free-Living Marine Nematode of the Genus Anticyathus Cobb, 1920 (Linhomoeidae) from Mangroves Sediment of Shenzhen and Shantou, China

Two new species belonging to the genus Anticyathus were discovered during an ecological investigation of mangrove sediment in China. Anticyathus shenzhensis sp. nov. and Anticyathus communis sp. nov. are both characterized by: annulated cuticles; ten cephalic setae in a circle; buccal cavity lined with six longitudinal reinforcements; amphids in broken circles or cryptic spirals, located at the very anterior of the head; pharynx with anterior cuticularized, gradually enlarging in posterior portion but without bulb; conical tail; arcuate spicules, the distal ends pointed, gradually broadening towards the proximal; gubernaculum has a dorsal–caudal apophysis; female with two opposed, outstretched ovaries. Anticyathus shenzhensis sp. nov. can be distinguished by ten cephalic setae of length about 2–4 µm; amphids diameter about 20–29% of corresponding body diameter; pharynx occupy 0.07–0.10 times of body length; cardia length about 25 µm; tail length 2.5–3.4 times of anal body diameter (abd) in males and 3.4–4.7 abd in females; spicules length 51–59 µm as arc and 0.71–1.04 abd; apophysis length 18–19 µm; female vulva at 52–56% of body length. Anticyathus communis sp. nov. is identified by ten cephalic setae length about 3–5 µm; amphids diameter about 20–32% of corresponding body diameter; cardia 17–27 µm long; tail length 3.6–4.5 abd in male, 5.3–5.5 abd in female; spicules proximal with distinctly cephalated, 0.74–0.96 abd; gubernaculum shape of “L”, consisting of sleeves around spicule and dorsal–caudal apophysis; five to seven pre-anal and seven to ten post-anal almost invisible papilla or papillae-like setae occur on each ventrally submedian line on the posterior body part of male; the tip of male tail with three slight elevation; female vulva at 52% of body length. A dichotomous key for the genus Anticyathus is given and 39 sequences of 18S rRNA gene from ten individuals of Anticyathus shenzhensis sp. nov. are provided in Genbank database.

Broken Circle: Premature Deindustrialization, Chinese Capital Exports, and the Stumbling Development of New Territorial Industrial Complexes

AbstractWhile inherited models of industrial development and the role of Foreign Direct Investment (FDI) in the developmental process associate urbanization and rising industrial output with the industrialization of employment, suggesting that the structural shift to a service-based job market is a sign of developmental “maturity,” such models fail to explain the secular tendency toward “premature deindustrialization” that has become increasingly evident in poor countries worldwide. These models cannot account for the deep bifurcations between output and employment, formality and informality, and industrialization and urbanization observable on the ground in the world's fastest growing cities. Meanwhile, the alternative models of critical development theorists tend to focus on failures of industrial takeoff and classic relations of dependency, none of which adequately account for the phenomenon being observed today. This paper explores an alternate explanation for premature deindustrialization, drawing from Marxian theories of technical change and the secular tendencies of capitalist development. The argument is illustrated with examples taken from the author's field work in Dar es Salaam, Tanzania, and the Pearl River Delta in China. Ultimately, the phenomenon of premature deindustrialization suggests that the great circle of development may collapse under its own contradictions before industrialization circumnavigates the globe.

Music, Form, and Crooked Time in Felix van Groeningen’s The Broken Circle Breakdown (2012)

Abstract This article explores the connections between musical and narrative crookedness in The Broken Circle Breakdown (2012). I propose a definition of narrative tactus to account for the increasingly disruptive impact of the film’s nonlinear structure and consider how the soundtrack both accentuates and counteracts the resulting sense of disjunction. Trigger warning: This article discusses the suicide of one of the film’s protagonists.

The broken circle method: a novel technique that enhances detection of Hill–Sachs lesions on internal rotation shoulder radiographs

To describe and test a new method that increases the conspicuity of a Hill-Sachs lesion on internal rotation (IR) radiographs. This study had institutional review board approval. A retrospective search for patients with a prior shoulder dislocation and a Hill-Sachs lesion documented on magnetic resonance imaging (MRI) was performed over a 10-year period identifying 256 test patients. In Part 1, the IR radiographs from test cases were randomised with controls, and three readers scored them independently for the defect. The readers were then taught the Broken Circle (BC) method and re-scored the radiographs. In Part 2, 15 cases of Hill-Sachs lesions that were missed by all readers in Part 1 were randomised with controls, and were shown to 25 radiology residents before (pre-test) and after (post-test) learning the BC method. A paired t-test was used to compare the differences in sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV). In Part 1, the sensitivity increased 19.7% (54.1%-73.8%; p<0.05) and NPV increased 10.8% (62.5%-73.3%; p<0.01). In Part 2, post-test sensitivity for residents increased 16.3% (55.2%-71.5%; p<0.0001), accuracy increased 13.4% (64%-77.4%; p<0.0001), and NPV increased 13.3% (40.8%-54.1%; p<0.0001) independent of the level of training. The change in accuracy was also statistically significant for every individual class. The BC method was an effective technique that facilitated detection of a Hill-Sachs lesion at all levels of training, and was useful as a teaching tool.

A functional near-infrared spectroscopy study of the effects of configural properties on sustained attention

Forty-five participants performed a vigilance task during which they were required to respond to a critical signal at a local feature level, while the global display was altered between groups (either a circle, a circle broken apart and reversed, or a reconnected figure). The shape in two of the groups formed a configurative whole (the circle and reconnected conditions), while the remaining shape had no complete global element (broken circle). Performance matched the results found in the previous experiments using this stimulus set, where a configural superiority effect was found to influence accuracy over time. Physiological data, measured using functional near-infrared spectroscopy, revealed elevated activation in the right pre-frontal cortex compared to the left pre-frontal cortex during the task. Additionally, bilateral activation was found in the conditions that formed configurative wholes, while hemispheric differences over time were found in the condition that did not. These findings suggest that configural aspects of stimuli may explain why non-typical laterality effects have been found in similar research.

Measurement of amplitude of accommodation in young persons

BackgroundThe aim was to evaluate the amplitude of accommodation using test objects designed with constant angular size corresponding to 6/6 visual acuity.MethodsIn total, 155 young volunteers with good ocular and systemic health aged between eight and 25-years were recruited for the study. A push‐up method was conducted, with the near‐vision target having a set of Landolt's broken circles. The angular size of the circles corresponded to a 6/6 visual acuity for various distances from 5.0-cm to 40-cm. To ensure precision of the object size, the electron beam lithographic technique was applied.ResultsA general trend in a reduction in amplitude with the progression of age is coincident with data from previous studies; however, the magnitudes of the volume of accommodation in our study are substantially lower.ConclusionTest objects with constant angular size can increase the accuracy of ‘push‐up’ accommodation measures.

The configural properties of task stimuli do influence vigilance performance.

Sixty-one participants performed a sustained attention task in which they were required to respond to a critical signal requiring feature discrimination. Three separate groups performed the task with different global display configurations. The local feature elements (directional arrow shapes) were displayed on either a circle, a circle broken apart or a reconnected figure. For two of the groups, the entire display consisted of a clear global shape (circle and reconnected), and for one of the groups, the display had no discernible global element (broken circle) despite the critical signal being the same for all the groups. Analyses of hit rate and A' scores indicated that the broken circle group had impaired performance compared to the global figure groups. A configural superiority effect was found in which performance was improved by having a global shape property to the entire display. These results provide a behavioural base for further research utilizing measures of cerebral activation, as cerebral activity during vigilance tasks may be dependent on both task difficulty and hierarchical aspects of the display. The configurable or hierarchical aspects of vigilance displays may be critical in understanding sustained attention performance and its hemispheric lateralization.

A novel plant-station and inter-plant-station topology analysis method

Summary In view of the requirement for instantaneity on power system topology analysis, a novel power system topology analysis method is proposed in this paper. For the plant-station topology method, the nodes that represent the circuit breakers are numbered according to the graph theory. On this basis, combining the main wiring characteristics and the switch status information, the plant-station topology is analyzed using the topological base theorem. When the switch status changes, the affected part of topology is modified using the radius search method, so that reforming of the topology is avoided and fast update of topology is guaranteed. When dealing with inter-plant-station topology, the incidence matrix notation method is used to judge the connectivity of the graph and mark the tree branches and link branches in the network, thus conducting static topology analysis of the power network. And then, when the network topology changes, the property of the changing branch is determined with the help of the loop matrix. On this basis, the local network topology and the loop matrix are updated by means of the broken circle method and the radius search method. Calculation examples verify the advantage of the proposed methods over traditional methods in calculation speed. With the proposed topology analysis methods, fast tracking of the switch status can be realized. Copyright © 2015 John Wiley & Sons, Ltd.

Model of Wagons’ Placing-In and Taking-Out Problem in a Railway Station and Its Heuristic Algorithm

Placing-in and taking-out wagons timely can decrease wagons’ dwell time in railway stations, improve the efficiency of railway transportation, and reduce the cost of goods transportation. We took the locomotive running times between goods operation sites as weights, so the wagons’ placing-in and taking-out problem could be regarded as a single machine scheduling problem,1pijCmax, which could be transformed into the shortest circle problem in a Hamilton graph whose relaxation problem was an assignment problem. We used a Hungarian algorithm to calculate the optimal solution of the assignment problem. Then we applied a broken circle and connection method, whose computational complexity wasO(n2), to find the available satisfactory order of wagons’ placing-in and taking-out. Complex problems, such as placing-in and transferring combined, taking-out and transferring combined, placing-in and taking-out combined, or placing-in, transferring, and taking-out combined, could also be resolved with the extended algorithm. A representative instance was given to illustrate the reliability and efficiency of our results.

Broken Circle: The Isolation of Franklin D. Roosevelt in World War II*

On the night of 21–22 June 1941, two different crises converged, changing the outlook for Franklin D. Roosevelt's presidency. German armies crashed into the Soviet Union. At nearly the same hour, forty-three-year-old Marguerite A. “Missy” LeHand, FDR's closest companion for two decades, was crippled by a stroke followed by a nervous breakdown. Roosevelt faced the challenges of a widened war at the moment when he lost a key member of his circle. Samuel I. Rosenman, a Roosevelt insider since the 1920s, pointed to LeHand as “the one indispensable person around the Executive Mansion and later around the White House.”1 He ranked her as “one of the five most important people in the U.S.”2 Indeed, LeHand operated as FDR's personal and political partner. As the New Dealer Raymond Moley put it, “Missy was as close to being a wife as he ever had—or could have.”3 Secretary of the Interior Harold L. Ickes detailed how LeHand's strengths fit Roosevelt's needs. After war broke out in Europe, Ickes wrote,

Precipitation Pattern Formation in the Presence of Imposed Concentration Gradients

AbstractThis study explored precipitation pattern formation under conditions where the inner electrolyte was inhomogeneously distributed. Depending on the imposed concentration gradient, various new precipitation structures such as bifurcated segments, budding patterns, and Liesegang rings segregated with broken circles have been observed. The analysis illustrates that, despite the presence of an imposed concentration gradient, the location of Xn of the nth band and its time of formation tn still satisfy a simple law, but the spacing (Xn+1/Xn) of the precipitation bands departs from a linear relationship once broken rings are developed in the medium.

The structure of chloroplast DNA molecules and the effects of light on the amount of chloroplast DNA during development in Medicago truncatula.

We used pulsed-field gel electrophoresis and restriction fragment mapping to analyze the structure of Medicago truncatula chloroplast DNA (cpDNA). We find most cpDNA in genome-sized linear molecules, head-to-tail genomic concatemers, and complex branched forms with ends at defined sites rather than at random sites as expected from broken circles. Our data suggest that cpDNA replication is initiated predominantly on linear DNA molecules with one of five possible ends serving as putative origins of replication. We also used 4',6-diamidino-2-phenylindole staining of isolated plastids to determine the DNA content per plastid for seedlings grown in the dark for 3 d and then transferred to light before being returned to the dark. The cpDNA content in cotyledons increased after 3 h of light, decreased with 9 h of light, and decreased sharply with 24 h of light. In addition, we used real-time quantitative polymerase chain reaction to determine cpDNA levels of cotyledons in dark- and light-grown (low white, high white, blue, and red light) seedlings, as well as in cotyledons and leaves from plants grown in a greenhouse. In white, blue, and red light, cpDNA increased initially and then declined, but cpDNA declined further in white and blue light while remaining constant in red light. The initial decline in cpDNA occurred more rapidly with increased white light intensity, but the final DNA level was similar to that in less intense light. The patterns of increase and then decrease in cpDNA level during development were similar for cotyledons and leaves. We conclude that the absence in M. truncatula of the prominent inverted repeat cpDNA sequence found in most plant species does not lead to unusual properties with respect to the structure of plastid DNA molecules, cpDNA replication, or the loss of cpDNA during light-stimulated chloroplast development.

Receptor specific downregulation of cytokine signaling by autophosphorylation in the FERM domain of Jak2

The tyrosine kinase, Janus kinase-2 (Jak2), plays a pivotal role in signal transduction through a variety of cytokine receptors, including the receptor for erythropoietin (Epo). Although the physiological relevance of Jak2 has been definitively established, less is known about its regulation. In studies assessing the roles of sites of tyrosine phosphorylation, we identified Y(119) in the FERM (band 4.1, Ezrin, radixin and moesin) domain as a phosphorylation site. In these studies, we demonstrate that the phosphorylation of Y(119) in response to Epo downregulates Jak2 kinase activity. Using a phosphorylation mimic mutation (Y(119)E), downregulation is shown to involve dissociation of Jak2 from the receptor complex. Conversely, a Y(119)F mutant is more stably associated with the receptor complex. Thus, in cytokine responses, ligand binding induces activation of receptor associated Jak2, autophosphorylation of Y(119) in the FERM domain and the subsequent dissociation of the activated Jak2 from the receptor and degradation. This regulation occurs with the receptors for Epo, thrombopoietin and growth hormone but not with the receptor for interferon-gamma.
