"Compendious extracts of strange and memorable things": sixteenth-century compilations and the new world
Creators: name: Young, Sandra M. (Sandra Michele)
Publisher: name: No Publisher Supplied
Year: 2008

description: The sixteenth-century compilation's encyclopaedic scope embraced widely diverse texts in accounting for the newly expanded world. I examine its representational methods for what they suggest of the period's habits of thought, and consider how these shape objects of knowledge. Michel Foucault's methodological tools facilitate a critique of epistemological constructions, but his characterizations of the sixteenth-century compilation as condemned "to never knowing anything but the same thing" do not adequately account for its contested meanings and shifts in form. I consider how Martin Waldseemüller deftly arranges disparate texts to authorize Vespucci's account of the New World and his map, announcing "America," managing the unsettling discrepancies between received knowledge and new ways of describing the world.Compilations instructing in the "arte" of navigation (Taisnier, Cortés) invoke the mathematical number's abstractions in the face of shifting landscapes, demonstrating that "knowing" is caught up with "doing." I caution against reading backwards through imperial history, assuming epistemological certainties. In Sebastian Münster's Treatyse of the Newe India, the presence of human subjects troubles cosmographical certainties, while also providing objects of curiosity for natural history. The possibilities of knowing become both troubled and enabled through encounter, evident also in Cabot's instructions to explorers. I analyze relational terms (novel, ancient, strange, monstrous, "our," beastly, peculiar, gentle, humane, barbarous, infidel), as the basis of Europe's identifications. Richard Hakluyt's early compilations, Divers voyages and Principall Navigations, create the possibility of a nation-specific imperial identity, through the gathering of texts.Close reading does not always bear out the rigidly temporal shifts identified by critics. While firsthand "experience" and "novelty" carry cachet, texts flaunting their novelty often echo existing texts. The ancients' authority remains an oft-cited method of authorizing disputed material, alongside methods considered new -- the mathematical number, instrumentation to measure the world, diagrammatic forms of representation (maps, astronomical charts) and narrative eye-witness accounts. The powerful critical methods of revisionist analysis warrant a recognition of the inevitably provisional nature of these abstractions and particularized investigations. Today as in the past, what we "know" to be "true" is a function of our institutional and political context. The coherence of our insights is always, inevitably, open to question.

description: We introduce a new "universality class" of artificial optical media - photonic hyper-crystals. These hyperbolic metamaterials with periodic spatial variation of dielectric permittivity on subwavelength scale, combine the features of optical metamaterials and photonic crystals. In particular, surface waves supported by a hyper-crystal, possess the properties of both the optical Tamm states in photonic crystals and surface plasmon polaritons at the metal-dielectric interface.
مقایسه کیفیتِ کالبدیِ زندگی در بحران های همه گیری از منظرِ ذهنِ ساکنین ؛ (نمونه پژوهی: محلات مسکونی معاصر ایران در بحران همه گیری کووید 19).
Publisher: name: دانشگاه کردستان
Year: 2023

description: محلات در همه گیری ویروس کرونا می توانند با بالا بردن کیفیت زندگی ساکنین نقش مهمی در مقابله با ویروس داشته باشند. از میان ابعاد موثر بر کیفیت زندگی در محلات، بعد کالبد به دلیل دخیل بودن در ساماندهی محیط و پاسخگویی به نیازهای ساکنین به منظور خود کفایی محلات ، جلوگیری از رفت و آمد به داخل شهرها و کاهش تراکم جمعیتی در مراکز شهری در جهت قطع زنجیره انتقال ویروس تاثیرشگرفی دارد. از همین رو پژوهش حاضر سعی دارد به مقایسه کیفیت کالبدی زندگی ساکنین محلاتِ معاصر سه مقیاس کلان شهری، شهرهای میانی و شهر کوچک در ایران بپردازد. روش پژوهش مقاله علی- قیاسی بوده و برای جمع آوری اطلاعات از منابع کتابخانه ای و پرسشنامه اینرنتی استفاده شده است. حجم جامعه آماری بر اساس فرمول دوم کوکران که به دلیل نامشخص بودن جمعیت 90 عدد نمونه رامطرح می کند، مشخص گردید. اما برای بالا بردن اعتبار پژوهش 300 پرسشنامه با شیوه نمونه گیری طبقه بندی شده توزیع گردید. برای تجزیه وتحلیل داده ها از آزمون کروسکال- والیس و تحلیل واریانس یک طرفه بهره گرفته شد. نتایج پژوهش حاکی از آن است که در بین شش دسته عوامل کالبدی، در کلان شهرها طبق میانگین نظرات، سلامت روانی(29/170)، طراحی محیطی(28/159)، نورپردازی(19/178) و سکونتی(01/188) ، در شهرهای میانی بهداشت محیطی (55/171) و در شهر های کوچک دسترسی (48/159) اولویت داشته اند. علاوه بر این دسته های بهداشت محیطی، نورپردازی، دسترسی،طراحی محیطی و سکونتی تفاوت چشمگیری بین سه گروه شهری ندارند و فقط دسته سلامت روانی با آماره خی دو (163/14) و سطح معناداری 001/ در بین سه مقیاس شهری دارای تفاوت معناداری است.

description: While it is well established that medical student learning about abortion is inadequate and lacks systemisation, there is little research on why this might be the case. This exploratory study draws on a survey sent to 438 medical educators at Australia’s 21 accredited medical schools through March–May 2021. Forty-eight educators responded to the survey. In this article, I examine their responses alongside policy and research on medical education to consider how curricula are determined. I conceptualise abortion exceptionalism–the singling out of abortion from other areas of medicine on the grounds that it is special, different, or more complex or risky than is empirically justified–as a mode of ‘stigma-in-action’, arguing that medical curricula are powerful sites for its reproduction and undoing.
Migrations of memory: postmemory in twentieth century ethnic American women's literature
Creators: name: Rice, Maria J.
Publisher: name: No Publisher Supplied
Year: 2007

description: "Migrations of Memory" studies the experience and resolution of inherited traumatic memory as depicted in the late twentieth-century narrative works of Ethnic and African American women writers. Often raised in the shadow of cultural or traumatic memories with which they have no direct experience, but deep affective connection, these writers from traditionally marginalized or subjugated groups find themselves, in the post1960s era, with greater opportunities than ever before to enter the mainstream of American society and separate themselves from their cultural pasts. My study argues that, in response to this possible loss of cultural moorings, contemporary Ethnic and African American women writers use narrative to theorize their relationship to their cultural inheritance and the influence that relation has on the formation of contemporary identity.This dissertation builds on the scholarship of Marianne Hirsch who coined the term postmemory to describe the relationship the children of survivors of cultural or collective trauma have to their parents' memories. Although Hirsch originated the term in relation to the Holocaust, my project utilizes the concept as a starting point for a theoretical approach to analyzing narrative representations of the generational impact of traumatic memory in a diversity of cultural contexts and resulting from a variety of experiences. The texts in my study have in common a process of identification, translation, and differentiation, whereby American-born protagonists first identify with or bear witness to their traumatic inheritance, then translate it into the terms of their livedexperience, and finally differentiate from it by re-articulating it in a form appropriate to their generational or cultural perspective. Analyzing the experience of inherited traumatic memory depicted in Gayl Jones' Corregidora, Octavia Butler's Kindred, Phyllis Alesia Perry's Stigmata, Edwidge Danticat's The Dew Breaker, Cristina Garc'sDreaming in Cuban, Maxine Hong Kingston's The Woman Warrior, and Nora Okja Keller's Comfort Woman, I argue ultimately that the resolution of postmemory requires representation and consistently engenders formal innovation.

description: We present results on the development of nanocomposite NiO:Au thin-film hydrogen sensors, which are able to detect hydrogen concentrations as low as 2 ppm in air, operating at low temperatures in the range 125-150C. Thin NiO films were sputter-deposited on oxidized silicon substrates. The structural, morphological, and nanomechanical properties of the films were investigated with respect to post-deposition annealing. Au nanoparticles were added on the NiO surface via pulsed laser deposition and the films were tested as hydrogen sensors before and after Au deposition. The performance of the NiO films as hydrogen sensors improved significantly in the presence of Au nanoparticles on the surface. The detection limit (lowest detectable hydrogen concentration) decreased by two orders of magnitude, while the response time also decreased by a factor of three.
More than a feeling: affect, narrative, neoliberalism
Creators: name: Smith, Rachel
Publisher: name: No Publisher Supplied
Year: 2008

description: This project examines a range of affective states as they are constructed in works of American literature and visual media. Focusing on affects that are implicated in processes of change -- fear, grief, perseverance, curiosity, and love -- it argues for the relevance of these transitional feelings to a cultural critique of neoliberalism. Proponents of neoliberalism emphasize values of autonomy, freedom, and progress, which paradoxically have also provided the traditional basis for humanist projects of resistance. When works of literature address change, the emotions and other bodily responses that emerge are often shaded with suffering and hesitation, and do not translate directly into recognizable forms of agency. Yet these seemingly passive modes of being are anything but static; security and predictability dissolve in these difficult states of transition. This entails pain, but also potential -- sadness, but also possibility.Literary works such as Don DeLillo's The Body Artist and Tony Kushner's Angels in America produce states of suffering that contradict the neoliberal assumption that appeals to change must call upon active expressions of individual agency. These works produce other corporeal sensations -- grief and perseverance -- that suggest modes of collective feeling at once strongly tied to transformative experiences and withdrawn from conventional forms of active production. Works of visual media from sources as diverse as television, contemporary cinema, and medical imaging produce other affects, among them fear and curiosity, which play pivotal roles in the neoliberal naturalization of progress. Yet some cultural constructions of curiosity, for example, also suggest that the desire for knowledge might produce new forms of social connection even within the very practices of neoliberal control. As cultural critics contend with these states of feeling, the affects produced by critique itself are at stake. This project concludes with an exploration of contemporary experiments in critical form that envision critique as a practice of love, forging unexpected links and untimely encounters with the world of events. The dissertation thus pursues a loose narrative that traces one possible affective trajectory from crisis to continuity, from breaking habitual structures of experience to forming new modes of social engagement and thought.

description: حواس پنجگانه بعنوان دریچه ارتباط انسان با محیط اطراف شناخته می شود، از اینرو درک فضا های شهری از طریق کانال های حسی مختلف، مانند: بینایی، شنوایی، بویایی، چشایی و لامسه صورت می گیرد. دریافت های ناشی از محرک های حسی، با وجود نقش با اهمیت خود در کیفیت بخشی به فضای شهری و ایجاد فضای یاد و خاطره، به نظر می رسد که امروزه کمتر مورد توجه طراحان شهری و معماران منظر قرار گرفته است؛ در حالی که یکی از راه های ارتقاء کیفیت فضاهای شهری، افزایش غنای حسی محیط به منظور بکارگیری تمامی حواس با هدف ایجاد جذابیت، حس تعلق به محیط، افزایش شمولیت و امکان فعالیت برای همه اقشار اجتماعی، سنی، جنسی و افراد کم توان از نظر ادراک و حواس مانند: افراد نابینا، ناشنوا و معلول، می باشد. پژوهش حاضر با توجه به اهمیت نظام ادراکات حسی در ادراک فضا و نقشی که این ادراک می تواند بر فرآیند شناخت و رفتار بگذارد، به بررسی کیفی ابعاد حسی فضا از طریق شناسایی و رتبه بندی دریافت های حسی گوناگون در فضاهای تجاری می پردازد. از همین روی محدوده بازار بزرگ تهران و مرکز خرید بام لند جهت مقایسه تطبیقی سطح کیفی مؤلفه های غنای حسی دو فضای شهری تجاری مدرن و سنتی انتخاب شده اند، تا به این مهم پرداخته شود که توجه به کیفیت غنای حسی در طراحی فضا های تجاری از گذشته تا به امروز دستخوش چه تغییراتی شده است؟ در راستای دستیابی به هدف پژوهش در بخش مبانی نظری و پیشینه تحقیق از روش کتابخانه ای و در بخش مطالعات میدانی، از دو روش «حس گردی » و «یادداشتبرداری حسی » استفاده شده است. نتایج حاصل از پژوهش بیانگر آن است که به طور کلی سطح کیفی مؤلفه های غنای حسی در بازار بزرگ تهران بیشتر از مرکز خرید بام لند بوده و در هر دو نمونه، حس بینایی بیشترین تحریک حسی و حس چشایی، کمترین میزان تحریک را داشته است. از طرفی امتیاز مربوط به تحریک حس بینایی در مرکز خرید بام لند بیشتر از بازار بزرگ تهران بوده که این امر خود گویای توجه بیشتر به بعد بصری محیط در طراحی های امروزین فضاهای تجاری می باشد.

Update on 3D Moving Mesh Simulations of Galactic Center Cloud G2

description: Using three-dimensional, moving-mesh simulations, we investigate the future evolution of the recently discovered gas cloud G2 traveling through the galactic center. From our simulations we expect an average feeding rate onto Sgr A* in the range of $(5-19) \times 10^{-8} M_\odot\mathrm{~yr}^{-1}$ beginning in 2014. This accretion varies by less than a factor of three on timescales of about 1 month, and shows no more than a factor of 10 difference between the maximum and minimum observed rates within any given model. These rates are comparable to the current estimated accretion rate in the immediate vicinity of Sgr A*, although they represent only a small (<10%) increase over the current expected feeding rate at the effective inner boundary of our simulations $(r_\mathrm{acc} = 750 R_S \sim 10^{15} \mathrm{cm})$. We also explore multiple possible equations of state to describe the gas. In examining the Br-$γ$ light curves produced from our simulations, we find that all of our isothermal models predict significant (factor of 10) enhancements in the luminosity of G2 as it approaches pericenter, in conflict with observations. Models that instead allow the cloud to heat as it is compressed do better at matching observations.

description: توسعه میان افزا که بخش اساسی انگاره رشد هوشمند شهری است، راهکاری عملی برای جلوگیری از گسترش کالبدی شهر در زمین های خالی و متروکه داخل مناطق شهری است که می تواند به احیا و تجدید حیات شهری کمک نماید . زمانی که در یک محدوده زیستی، پدیده پراکنده رویی کالبدی پدیدار شود، می توان گفت که درون شهر، فضاهای بلااستفاده، رها شده، ناکارآمد و فرسوده شکل می گیرد، از این روست که توجه و برنامه ریزی جهت استفاده از این فضاها اهمیت پیدا می کند. در واقع رشد هوشمند شهری یکی از راهکارهای اساسی در پاسخ به پراکنده رویی است؛ بنابراین توجه به اصول توسعه میان افزا در محدوده های دارای ظرفیت شهر مانند: بافت های فرسوده، مخروبه ها، اراضی بایر و بافت های ناکارآمد شهری می تواند به عنوان یکی از راهبرد های اساسی برای دستیابی به رشد هوشمند شهری کمک نماید. هدف پژوهش حاضر نیز شناسایی محدوده های با قابلیت توسعه درون زا با تاکید بر شاخصهای قابل دست یابی از داده های دورسنجی شامل بخش های فرسوده و زمین های بایر در محدوده قانونی شهر اهواز است. برای این منظور پس از تهیه و استانداردسازی تصاویر لندست و IRS، با استفاده از مدل های WS و MLC به طبقه بندی و استخراج بافت های مورد نظر پرداخته و سپس در GIS با ترکیب خروجی های پیشین، نقشه کلاسه بندی مناطق قابل پیشنهاد توسعه میان افزا ارایه گردیده است. نتایج تحقیق نشان داد که از مساحت 18650 هکتاری محدوده قانونی شهر اهواز، بیش از 6726 هکتار (شامل مناطق شناسایی شده بایر و بافت فرسوده) قابلیت توسعه میان افزا را دارا می باشند. این مقدار 36.2 درصد از مساحت شهر را شامل می شود.
Redefining political theatre: masochism and the problem of identity
Creators: name: Mustamäki, Piia J.
Publisher: name: No Publisher Supplied
Year: 2008

description: This dissertation proposes that the psychoanalytic concept of masochism is indispensable in interpreting race and gender politics in contemporary American theatre by women of color. The plays I examine -- Suzan-Lori Parks's Venus, Adrienne Kennedy's The Ohio State Murders and Alice Tuan's Hit -- use race and gender to expose the manner in which the democratic principles of modernity are not fulfilled, despite the appearance of equality. They do this, paradoxically, by staging the ways in which social factors might produce political conformity rather than defiance. Masochism, I argue, offers a compelling critical lens into the failures of liberal democracy as experienced by women of color. These failures surface as crises in the idealized concept of the autonomous, free-willing subject, a concept on which the democratic principles are based. Unlike much political theatre, the plays in this study do not represent efforts to achieve such an idealized subject position. Instead they depict masochistic subjects for whom such positions are unavailable, delineating the inadequacies of liberal democracy as they pertain to racialized and gendered subjects in the nineteenth and twentieth century.I proceed from the recognition that masochism, an inherently cultural phenomenon, is an acted-out symptom of the discrepancy between modernity's ideals of sovereignty and equality and a differently experienced reality. More than merely serving as a mechanism of sexual gratification, masochism is a complex psychic and social matrix, always both adaptive and defensive. It is in fact a paradoxical act of resistance, a defense mechanism for those for whom autonomy is out of reach. Through close readings of the three plays, I provide an example of masochism's usefulness in interpreting the politics in dramas that represent women of color whose masochistic behavior perpetuates rather than defies their oppression. Formally and thematically closer to the theatre of Jean Genet than to that of the Black Arts Movement or feminist groups, these plays foreground a new way of representing race and gender-based social criticism in the theatre.

description: First cycle games (FCG) are played on a finite graph by two players who push a token along the edges until a vertex is repeated, and a simple cycle is formed. The winner is determined by some fixed property Y of the sequence of labels of the edges (or nodes) forming this cycle. These games are traditionally of interest because of their connection with infinite-duration games such as parity and mean-payoff games. We study the memory requirements for winning strategies of FCGs and certain associated infinite duration games. We exhibit a simple FCG that is not memoryless determined (this corrects a mistake in \it Memoryless determinacy of parity and mean payoff games: a simple proof by Björklund, Sandberg, Vorobyov (2004) that claims that FCGs for which Y is closed under cyclic permutations are memoryless determined). We show that /Theta(n)! memory (where n is the number of nodes in the graph), which is always sufficient, may be necessary to win some FCGs. On the other hand, we identify easy to check conditions on Y (i.e., Y is closed under cyclic permutations, and both Y and its complement are closed under concatenation) that are sufficient to ensure that the corresponding FCGs and their associated infinite duration games are memoryless determined. We demonstrate that many games considered in the literature, such as mean-payoff, parity, energy, etc., satisfy these conditions. On the complexity side, we show (for efficiently computable Y) that while solving FCGs is in PSPACE, solving some families of FCGs is PSPACE-hard.

Religion in postmodern science fiction: a case study in secularity
Creators: name: Pizzino, Christopher J.
Publisher: name: No Publisher Supplied
Year: 2008

description: Using recent debates in the humanities and social sciences, this dissertation argues that the category of the secular is currently being critiqued, contested, and modified from within. This dissertation considers postmodern science fiction, particularly the subgenre of cyberpunk, as a literary instance of this contestation. This study focuses on the ways cyberpunk fiction constructs religious others against which to define its protagonists, and on the way that the distinction between the secular and the religious is understood using concepts of subjectivity and history. Further, this work argues that the secular concepts common to postmodern science fiction can be considered a key expression of secular subjectivity as it undergoes new challenges to its legitimacy. Further, using examples from postmodern science fiction film, this work considers the ways that secular subjectivity may be undergoing further modifications that challenge the opposition of the religious to the secular.
Nucleosynthesis of elements between Sr and Ag in neutron- and proton-rich neutrino-driven winds

description: Neutrino-driven winds that follow core collapse supernovae were thought to be the site where half of the heavy elements are produced by the r-process. Although recent hydrodynamic simulations show that the conditions in the wind are not enough for the r-process, lighter heavy elements like Sr, Y, and Zr can be produced. However, it is still not clear whether the conditions in the wind are slightly neutron rich or proton rich. Here we investigate the nucleosynthesis in neutrino-driven winds for both these conditions and systematically explore the impact of wind parameters on abundances. Our results show the difficulty of obtaining a robust abundance pattern in neutron-rich winds where also an over production of Sr, Y, and Zr is likely. In proton-rich conditions, the abundances smoothly change when varying wind parameters. Constraints for wind parameters and neutrino energies and luminosities will soon become available by combining nucleosynthesis studies, like the one presented here, with new and future experimental data and observations.

description: In this review I first describe the nature of the three kinds of High-Mass X-ray Binaries (HMXBs), accreting through: (i) Be circumstellar disc, (ii) supergiant stellar wind, and (iii) Roche lobe filling supergiants. I then report on the discovery of two new populations of HMXBs hosting supergiant stars, recently revealed by a wealth of new observations, coming from the high energy side (INTEGRAL, Swift, XMM, Chandra satellites), and complemented by multi-wavelength optical/infrared observations (mainly ESO facilities). The first population is constituted of obscured supergiant HMXBs, the second one of supergiant fast X-ray transients (SFXTs), exhibiting short and intense X-ray flares. I finally discuss the formation and evolution of HMXBs, constrain the accretion models (e.g. clumpy winds, transitory accretion disc, magneto-centrifugal barrier), show evidences suggesting the existence of an evolutionary link, include comparisons with population synthesis models, and finally build a consistent scenario explaining the various characteristics of these extreme celestial sources. Because they are the likely progenitors of Luminous Blue Variables (LBVs), and also of neutron star/black hole binary mergers, related to short/hard gamma-ray bursts, the knowledge of the nature, formation and evolution of these HMXB populations is of prime importance.

Navigating interpretive authorities: women readers and reading models in the eighteenth century
Creators: name: Steele, Kathryn Lenore
Publisher: name: No Publisher Supplied
Year: 2008

description: Challenging existing notions of the oppositional reader, this dissertation proposes the model of limited interpretive authority as a new way of understanding reading practices in eighteenth-century England. It examines the women readers of Samuel Richardson's Clarissa as illustrations of this concept. Chapter 1, a literature review, suggests that even as methodologies become more flexible, the modern, individual, and secular reader continues to inform studies of historical reading. Arguing that the field requires a reading model describing more limited individual interpretive authority, this chapter turns to eighteenth-century instructions for reading the Bible. These texts employ a language of self-discipline and self-censorship that characterizes reading which negotiates, instead of rejecting, interpretive authority. Chapter 2 explores the historically problematic emphasis on oppositional reading in the study of women readers. A review of these methodological problems is followed by an examination of Hester Mulso Chapone's 1773 Letters on the Improvement of the Mind. This influential conduct book theorizes and recommends socially-embedded reading practices; in recuperating novelistic reading practices for the reading of the Bible, this text reflects a key change in reading practices. The chapter argues for extending the search for evidence of reading to the didactic texts usually believed to merely constrain readers. The final two chapters examine the implied readers and historical readers of Samuel Richardson's 1747-48 novel Clarissa. Chapter 3 examines internal reading strategies. Clarissa's interpretive practice changes as she moves from acting in the social world to spiritual retreat. Silences in response to her family's coercion--representing a form of passive disobedience--are replaced by a refusal to narrate. This refusal signifies Clarissa's removal from the interpretive conflicts of the material world. Clarissa's self-transcendence invites us to imagine some readers' desire for similar self-transcendence. Using both published and archival letters, Chapter 4 tests and extends the models of reading proposed by the novel itself. Anna Howe, this chapter proposes, not Clarissa, provides the model of reading most often employed by readers. Reading like Anna Howe, or reading in a mode of filial disobedience, reveals a way to navigate, without necessarily rejecting, the interpretive dictates of patriarchy.

description: In this work we aim at applying automata techniques to problems studied in Dynamic Epistemic Logic, such as epistemic planning. To do so, we first remark that repeatedly executing ad infinitum a propositional event model from an initial epistemic model yields a relational structure that can be finitely represented with automata. This correspondence, together with recent results on uniform strategies, allows us to give an alternative decidability proof of the epistemic planning problem for propositional events, with as by-products accurate upper-bounds on its time complexity, and the possibility to synthesize a finite word automaton that describes the set of all solution plans. In fact, using automata techniques enables us to solve a much more general problem, that we introduce and call epistemic protocol synthesis.

description: آسیب های ناشی از بحران جهانی بیماری کرونا، شهرها و مدیریت شهری را با وضعیت دشواری رو به رو کرده است. درجه و شدت این آسیب ها در اسکان های غیررسمی و زاغه ها به دلیل خصوصیات و ویژگی های کمی و کیفی پایین این مناطق، بیشتر می باشد. هدف اصلی تحقیق حاضر بررسی نقش سازمان های مردم نهاد در ارتقاء تاب آوری سکونتگاه های غیررسمی شهر ارومیه در برابر پاندمی کووید- 19 می باشد. روش تحقیق پژوهش حاضر، توصیفی-تحلیلی با رویکرد کمّی بوده است. جامعه آماری پژوهش شامل کلیه سازمان های مردم نهاد فعال در شهر ارومیه با زمینه فعالیتی مقابله با کووید-19 بوده است. شیوه نمونه گیری تحقیق نیز به صورت تصادفی ساده و به روش قرعه کشی می باشد. داده ها و اطلاعات گردآوری شده در این پژوهش، با استفاده از آمار توصیفی میانگین و آزمون های کولموگروف-اسمیرنوف و فریدمن در نرم ا فزار Spss تجزیه و تحلیل شده اند. نتایج نشان می دهد که میزان نقش و فعالیت سازمان های مردم نهاد جهت ارتقاء تاب آوری سکونتگاه های غیررسمی شهر ارومیه در برابر کووید-19 در مولفه اجتماعی-فرهنگی با میانگین 66/3 متوسط رو به بالا، در مولفه اقتصادی-معیشتی با میانگین 95/2 متوسط رو به پایین و در مولفه کالبدی - محیطی با میانگین 11/3 در حد متوسط بوده است. بدین منظور پیشنهاد می شود که با توجه به تاثیری که بیماری فراگیر کووید-19 بر اقتصاد و گسست سرمایه اجتماعی شهروندان ساکن در سکونتگاههای غیررسمی می گذراد، سازمان های مردم نهاد تمرکز خود را بر روی جذب حمایت های اقتصادی و اجتماعی بخش های دولتی، عمومی و خصوصی قرار دهند. همچنین لازم است توجه ویژه ای به ارائه مشوق ها و بسته های حمایت مالی برای حفاظت از سلامت و امنیت اقتصادی و اجتماعی مردم ساکن در این سکونتگاهها شود.
Cross-ethnic mediums and the autobiographical gesture in twentieth century American literature
Creators: name: Jaffe-Foger, Miriam
Publisher: name: No Publisher Supplied
Year: 2008

description: One of the most definitive aspects of twentieth century literary studies has been the move to group fiction by ethnic minorities into separate categories according to the authors' ethnicities. Among these categories, "African American literature" and "American Jewish literature" have emerged as two of the most prevalent. This study suggests that African American authors and American Jewish authors have resisted the confines of ethnic categorization by imagining themselves as each other and by using each other's cultural property within their writing. Previous scholarship on the literary relationship between African Americans and American Jews tends to position the two groups in conflict, but the subjects of this study--Franz Boas, Zora Neale Hurston, James Weldon Johnson, Fran Ross, Bernard Malamud, and Philip Roth--employ cross-ethnic mediums in pursuit of a common goal: to be considered as American individuals without the boundaries of their ethnic identities. The literary tactic that indicates each subject's struggle with the boundaries of their own ethnic identities is the autobiographical gesture--the artful use of one's own experiences. In each subject's use of the autobiographical gesture, the self as other serves as a means to work against the bounds of ethnic identity.
Conversing with books: reading the eighteenth-century British periodical essay in Jeffersonian America
Creators: name: Squibbs, Richard J.
Publisher: name: No Publisher Supplied
Year: 2007

description: The periodical essay is the sole British literary genre to have emerged and declined within the chronological eighteenth century. It appeared in London during the reign of Queen Anne, and by the end of the century had virtually disappeared amidst a new culture of magazine publication. This study charts the various guises the genre assumed across the eighteenth century as essayists in Edinburgh, Philadelphia and Manhattan adapted the worldviews expressed in the earlier London essays to the particular circumstances of their cities. What the English essayists and their readers had regarded as timely, topical conversations in print about manners and culture became something more to their Scottish and American avatars. The periodical essay for them became a medium for witnessing historical change, a genre centrally concerned with what might have been. Each of the first three chapters focuses on a particular figure within the periodical essay tradition, showing how each one articulates a moral relationship to civil society that the essays' authors encourage their readers to adopt. The Censor in chapter one represents a certain manner of reading, one that means to prompt social self-reflection in the name of a broader, more comprehensive civic awareness. Chapter two takes the whimsical essayistic persona as its subject, reading whimsicality as a principled resistance to the rationalizations of time management in a developing market society, and as a direct challenge to the herd mentality periodical writers see as the real face of liberal individualism in its consumer-market guise. My third chapter shows how the Templar, a young law student who finds himself drawn increasingly to literature, comes to figure in Scottish and American essay series a perception that belletristic writing must assume a law-like moral function in recording for posterity these writers' exemplary resistance to civic decline. My final chapter then reads Washington Irving's History of New York as self-consciously drawing upon these elements of the periodical tradition to create a sort of literary conscience for a new American polity seemingly intent on reducing all of civic life to an imaginatively impoverished market for consumer goods.
Exchange interaction and tunneling induced transparency in coupled quantum dots

description: We investigate the optical response of quantum dot molecules coherently driven by polarized laser light. Our description includes the splitting in excitonic levels caused by isotropic and anisotropic exchange interactions. We consider interdot transitions mediated by hole tunneling between states with the same total angular momentum and between bright and dark exciton states, as allowed by spin-flip hopping between the dots in the molecule. Using realistic experimental parameters we demonstrate that the excitonic states coupled by tunneling exhibit a rich and controllable optical response. We show that through the appropriate control of an external electric field and light polarization, the tunneling coupling establishes an efficient destructive quantum interference path that creates a transparency window in the absorption spectra, whenever states of appropriate symmetry are mixed by the carrier tunneling. We explore the relevant parameter space that allows probing this phenomenon in experiments. Controlled variation of applied field and laser detuning would allow the optical characterization of spin-preserving and spin-flip hopping amplitudes in such systems, by measuring the width of the tunneling-induced transparency windows.

Second nature: the discourse of habit in nineteenth-century British realist fiction
Creators: name: Allen, Kristie M.
Publisher: name: No Publisher Supplied
Year: 2008

description: Second Nature: The Discourse of Habit in Nineteenth-Century British Fiction explores ideas about habit in the nineteenth century. Even as the discourse of habit took shape in psychology studies, self-help tracts, and social reform inquiries, its aesthetic realization in the novel performed the crucial task of synthesizing these psychological and sociological perspectives. My dissertation examines the ways realist writers sought to reconceive the relationship between social determination and self-improvement. I argue that they were compelled to develop new modes to represent consciousness in ways that would correspond to new theories of evolutionary progress, institutional change, and even the physiology of the brain. As science increasingly pointed toward the amorality of natural evolution, Victorian novelists derived moral meaning from new ways of narrating the ordinary experiences that constituted people's "second nature." In revealing the rich historical debates about habit, my dissertation contributes to our understanding of the reciprocally shaping forces of scientific ideas about the mind and realist narrative techniques. Chapter one analyzes the political, scientific and aesthetic concerns with habit, demonstrating several contradictions at work in the Victorian formulation of second nature by tracing its genealogy. The texts I examine--parliamentary reports, the Preface to the Lyrical Ballads, and evolutionary controversies, among others--suggest that the training and reforming of habit was understood as a key to social reform. In the following three chapters I consider the intricate ways that Charles Dickens, George Eliot, and Thomas Hardy imagine and depict the intersecting social and psychological origins of habit. Dickens's novel Dombey and Son investigates the ethical responsibility for one's socialization and unconscious life. Chapter two's reading of The Mill on the Floss argues that Eliot's engagement with new physiological understandings of habit shapes both her ideal of sympathy and her sense of the importance of reimagining conventions. My final chapter contends that Hardy's work refutes earlier realist claims about the potential of habit for self-reform. Taken together, these fictions demonstrate an aesthetic experiment with scientific notions of subjectivity, examining how repetition, personal disposition, desire, environment, and early training are entailed in the process of becoming a moral subject.
Estranging science, fictionalizing bodies: viral invasions, infectious fictions, and the biological discourses of "the human," 1818-2005.
Creators: name: Diehl, Laura Anne
Publisher: name: No Publisher Supplied
Year: 2008

description: In 1818, Mary Shelley's novel Frankenstein causes science and literature--two different discourses, two different signifying systems, two different realities--to collide. As it addresses the givenness, or "naturalness," of "the human," Frankenstein reimagines the putative boundary between the human and the nonhuman, a fictive border made perceptible by contemporary scientific investigation. Catalyzing a new genre, science fiction, Shelley estranges the enlightenment discourse of "reason," revealing it as a highly regulative structure through which societies are forged and bodies governed. "Estranging Science, Fictionalizing Bodies: Viral Invasion, Infectious Fictions, and the Biological Discourses of 'the Human,' 1818-2005," posits a mutually infective relationship between science and literature. It both exposes the logic of purification that delimits "modern" forms of knowledge as discursively distinct (science v. literature) and considers how this distinction informs the evolutionary/philosophical shifts in how we think about the possible, the human, and the novel. Since literature plays a significant role in the history of science and science a significant role in the history of literature, the dissertation uses each imaginary technology to interpret the other. In so doing, it defamiliarizes and recontextualizes not only individual texts, but entire literary histories and scientific discourses that are rarely thought of as science fiction. Finally, the dissertation argues that the question of "the human," of what we invoke when we invoke "the human," emerges most powerfully through an interpretive matrix of science and literature, genre and the novel. Though radically different methods of shaping those narratives that concern us all, science and literature both employ the process by which novelty enters the world and affects our experience of the self and the relatedness of bodies. The epistemological--and epidemiological--encounters the dissertation explores make possible a whole range of new entities, properties, and kinships that connect through unfamiliar evolutionary and intellectual bonds. "Human nature" emerges as neither essential nor unchanging, random nor inevitable.
Cosmology with quantum matter and a classical gravitational field: the approach of configuration-space ensembles

description: I consider the formulation of hybrid cosmological models that consists of a classical gravitational field interacting with a quantized massive scalar field in the formalism of ensembles on configuration space. This is a viable approach that provides an alternative to semiclassical gravity. I discuss a particular, highly nonclassical solution in two approximations, minisuperspace and spherically-symmetric midisuperspace. In both cases, the coupling of the quantum scalar field and classical gravitational field leads to a cosmological model which has a quantized radius of the universe.
