Crowd escape event detection has become one of the hottest problems in intelligent surveillance filed. When the 'escape event' occurs, pedestrians will escape in a disordered way with different velocities and directions. Based on these characteristics, this paper proposes a Direction-Collectiveness Model to detect escape event in crowd scenes. First, we extract a set of trajectories from video sequences by using generalized Kanade-Lucas-Tomasi key point tracker (gKLT). Second, a Direction-Collectiveness Model is built based on the randomness of velocity and orientation calculated from the trajectories to express the movement of the crowd. This model can describe the movement of the crowd adequately. To obtain a generalized crowd escape event detector, we adopt an adaptive threshold according to the Direction-Collectiveness index. Experiments conducted on two widely used datasets demonstrate that the proposed model can detect the escape events more effectively from dense crowd.

Leslie Marmon Silko's Storyteller does not belong to a typical category of books, for it looks more like a family album with photographs, poems and Pueblo narratives as well as short stories authored by her. This 'book' without any chapters defies a traditional concept of books we are familiar with. In addition to refusing to be labelled as a conventional book, I argue, Storyteller defies the tradition of Western personal writing in that it shows the collective power of stories. That is, stories have the collective power which is impersonal beyond personal, internalized identity. It does not mean, however, the collective power comes from groups rather than individuals. It is not the conventional opposition of group and individual but that of group and collectiveness that matters here. I draw a distinction between group and collectiveness on the ground that the former actually groups individuals into categories with which individuals identify themselves. It is not group but collectiveness where stories find their power. "Storyteller," the first of eight short stories in the book, tells the story of an unnamed protagonist, a Yupik Eskimo girl, who takes revenge of her parents who died after drinking poisoned alcohol sold by a white storeman. There are four layers of stories in this short story. The first one is the old man's story of a blue glacier bear; the second one is a revenge story of the Yupik girl; the third one is a story told by the girl to the attorney after being arrested for the death of a storeman. And the final one is the story told to us by Silko, entitled "Storyteller." Although the structure of story within story resembles a technique of metafiction at a glance, it surely is a characteristic of Pueblo narratives in general, according to Silko. This kind of stories within stories refers to the collective power of story which, like a spider's web with many little threads radiating from the center and crisscrossing one another, is also a characteristic of stories on the Web today.

Written as her last collaboration with the Provincetown Players, Susan Glaspell's The Verge is an exceptional play in that its formal experiment and modernist theme are clear of her general modernist ambivalence which combines a uniquely American and feminist expression of the modernist spirit with rather conventional forms. Following critics' brief and generalizing comments on the play's protagonist embodying modernist formalism and alienation, this paper offers a full and concrete survey detailing the tenets and the slogans of Modernism inlaid in the play. Its main argument is that Glaspell strategically deployed the metaphysics of egoism, anarchic hostility to the collectiveness of bourgeois society, and formalist preoccupation in Modernism in representing a female egoist's longing for a new order of society, illustrating an intersection between Modernism and feminism. It concludes that The Verge is an extremely rare case of modernist literature where a play, allegedly the least modernist genre of all according to Christopher Innes, exemplifies the "eloquent critical acts entangled in the creative work" which Michael Levenson lists as a distinct feature of modernist texts.

트랜스미디어 스토리텔링은 다양한 미디어 플랫폼에 기반한 다수의 콘텐츠가 하나의 세계를 구현하는 것으로, 디지털 컨버전스 시대에 새롭게 나타난 양식을 말한다. 하나의 세계를 창조해 내기 위해 각기 다른 미디어가 개별적인 세계를 유기적으로 창출하여 다양한 의미를 생산해 내는 트랜스미디어 스토리텔링은 창작자의 영역을 넘어 소비자의 영역에까지 변화를 일으킨다. 트랜스미디어 스토리텔링의 첫 번째 특성은 창작의 공동 제작과 향유의 집단 지성이다. 두 번째 특성은 교차와 결합을 통한 스토리 분화로 소비자에게 새로운 경험과 통찰을 제시하는 것이다. 마지막 특성으로는 세계 구축을 위한 관계 맺기를 통해 콘텐츠가 수렴되고 발산되는 과정을 들 수 있다. 트랜스미디어 스토리텔링은 창작자와 소비자들이 만나는 여러 지점을 통해 모아지고 전개되는 것이다. 이러한 트랜스미디어 스토리텔링의 특성은 다양한 미디어 플랫폼을 통해 구축되는 트랜스미디어 콘텐츠를 분석하는 기반으로 작용할 것이다.

Samuel Beckett's literary sympathies with underdogs enslaved to authoritative figures, found in his earliest plays, continued in a more or less subdued form in his later plays: Not I is a good case in point thematizing a social authority psychologically embedded within a subject. The incessant bouts of self-defense, or confessional, which Mouth carries out on a dark stage is directed to an inner authority. In Civilization and Its Discontents (1931), Freud's diagnosis for individuals torn between the opposite calls of a social order-- which he called, by turns, civil society, civilization, and culture--and of individual freedom was a "neurosis." What Not I dramatizes seems to be this state of neurosis suffered by a subject bound to the contradictory calls of an internal social authority, which forces Mouth to carry on a confessional till she obtains a symbolically/linguistically viable social title of "I," and of her individualistic denial of the position("what?..who?..no!.. she!.."). Mouth's ordeal on stage does not signify the psychological pressure of the social system, with its disciplinary measures of guilt, justice, and punishment, triumphs over individualistic irregularities and abnormalities, for her "maddened" confession will never see its closure. The opposite psychological forces at work inside Mouth, who is both "in" and "out[side]" "this world," will keep engaging in an eternal battle. In a way, she is a perfect parable about us humans living within a system, "discontent" and hung between the contradictory calls of individualism and social collectiveness.

Skeletal muscle tissues feature cellular heterogeneity, including differentiated myofibers, myoblasts, and satellite cells. Thanks to the presence of undifferentiated myoblasts and satellite cells, skeletal muscle tissues can self-regenerate after injury. In skeletal muscle regeneration, the collective motions among these cell types must play a significant role, but little is known about the dynamic collective behavior during the regeneration. In this study, we constructed in vitro platform to visualize the migration behavior of skeletal muscle cells in specific conditions that mimic the biochemical environment of injured skeletal muscles. We then visualized the spatiotemporal distribution of stresses arising from the differential collectiveness in the cellular clusters under different conditions. From these analyses, we identified that the heterogeneous population of muscle cells exhibited distinct collective migration patterns in the injury-mimicking condition, suggesting selective activation of a specific cell type by the biochemical cues from the injured skeletal muscles.
