Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

Amrit Singh and the Birmingham Quean: fictions, fakes and forgeries in a vernacular counterculture

For a literary critic preparing a scholarly edition of a text like this within an epistème that disparages the theory underpinning it for being tainted with the gestural idealism of 1968 and the neon-glare of 1980s high postmodernism, the crucial question is how to reconcile the commitment to authenticity ingrained in historicist textual studies (perhaps the critic’s only viable disciplinary inheritance) with the author’s implicit antagonism to any such quietist approach. The encounter inevitably becomes a battle of wills. In the course of the current project, this theoretical struggle escalates exponentially as doubts concerning the authenticity (and indeed the existence) of both writer and manuscript are multiplied. If a thesis can be retrospectively extrapolated from this project, it is the argument that fiction is demonstrably a tractable forum for research in the Arts and Social Sciences: all the more tractable for its anti-authenticity. The critic’s loss is the novelist’s gain. Specifically, in this case, the faithful historian of late twentieth century literatures, languages and cultures can solve the key dilemma of the subject by working under the auspices of Creative Writing. Only in this way can justice be done to the most cogent intellectual trend of the posmodern period (perhaps its defining feature): one that revelled in its own pluralities, ambiguities and contradictions, and resisted all the unifying, teleological models of ‘history’ that had been implicated in the century’s terrible ‘final solutions’. In other words, only fiction can tell the history of a culture that rejects that history. If this means condoning forgery… so be it

CORPORATE SOCIAL RESPONSIBILITY IN ROMANIA

The purpose of this paper is to identify the main opportunities and limitations of corporate social responsibility (CSR). The survey was defined with the aim to involve the highest possible number of relevant CSR topics and give the issue a more wholesome perspective. It provides a basis for further comprehension and deeper analyses of specific CSR areas. The conditions determining the success of CSR in Romania have been defined in the paper on the basis of the previously cumulative knowledge as well as the results of various researches. This paper provides knowledge which may be useful in the programs promoting CSR.Corporate social responsibility, Supportive policies, Romania

Penned in the first person : setting and theme in the lyrics of Thomas Hardy

Bibliography: pages 240-258.This thesis arises from the conviction that the Hardyan quality of mind, a mind at once tentative and courageous, is of supreme importance in our time and is most distinctly and decisively present in Hardy's short poems. The chief aim of this thesis has been to offer students of Hardy thematic and aesthetic guidelines for reading his poems so as to encounter that quality of mind first-hand. In order to develop those guidelines, I have rooted them in primary materials and biographical details germane to demonstrating Hardy's achievement as a poet. The main title of this thesis, for instance, is meant to emphasise the complex relationship between the poet and the man: culled from the preface of his third volume of verse, Time's Laughingstocks and Other Verses, the simple yet apposite phrase, "penned in the first person," is the invention of Hardy himself

"Such friends": effects of extensive cluster group interaction on the development of creative writers

Four writers and their associated cluster groups were studied through content analysis of numerous biographies. These include W. B. Yeats and the Irish Literary Renaissance (1897-1906), Virginia Woolf and the Bloomsbury Group (1907-1915), Gertrude Stein and the American Expatriates in Paris (1921-1930), and Dorothy Parker and the Algonquin Round Table (1919-1928). The groups were analysed with reference to the social psychological research on group roles, structure, and interaction patterns; climate, goals and values; and cohesiveness. The writers’ development was analysed with reference to identity, differentiation, productivity and risk-taking. The analyses of all four groups-despite their diversity of membership, nationality and location-revealed remarkably similar structuring of roles and interaction patterns. The core of each group consisted of the writer and a co-dependent who hosted the group and supported the writer. Closely associated with these two roles were three others, each of which was crucial to both the task and socio-emotional functioning of the group. These included the “Irritant,” whose behavior served to focus tensions and stimulate periodic realignments within the group; the “Angel” who served to pull the group together and allow members to affirm their commonalties; and the “Sponsor” whose lack of social skills, which allowed other members to affirm their own normality, was compensated by his ability to marshal the resources to create outlets for the others’ work. Finally each group contained three additional roles which served crucial bridging functions between the group and the wider world. These included the “Odd One Out,” who had both close supportive ties to the core of the group and strong connections to other groups; the “Link,” who used his personal ties within the cultural and political establishment to promote the careers of group members; and the “Bridge” who raised sociological, political and cultural issues crucial to the core values of the group and the writings of its members. The shared values, goals and complementary patterning of roles allowed each of the groups to sustain an inordinately high and lengthy level of cohesiveness for an informal cluster group. The sizeable benefits which accrued to the four writers at the core of these groups included: (1) greatly enhanced organization and structure in both personal and professional life; (2) enhanced self-concept and public visibility as writers; and (3) increased differentiation and productivity in their writing
