    An unfolding signifier: London's Baltic Exchange in Tallinn

    Get PDF
    In the summer of 2007 an unusual cargo arrived at Muuga and Paldiski harbors outside Tallinn. It consisted of nearly 50 containers holding over 1,000 tons of building material ranging from marble columns, staircases and fireplaces, to sculpted allegorical figures, wooden paneling and old-fashioned telephone booths. They were once part of the Baltic Exchange in the City of London. Soon they will become facets of the landscape of Tallinn. The following article charts this remarkable story and deploys this fragmented monument to analyze three issues relating to the Estonian capital: the relocation of the ‘Bronze Soldier’, the demolition of the Sakala Culture Center, and Tallinn’s future role as European Cultural Capital in 2011

    Empty spaces and the value of symbols: Estonia's 'war of monuments' from another angle

    Get PDF
    Taking as its point of departure the recent heightened discussion surrounding publicly sited monuments in Estonia, this article investigates the issue from the perspective of the country's eastern border city of Narva, focusing especially upon the restoration in 2000 of a 'Swedish Lion' monument to mark the 300th anniversary of Sweden's victory over Russia at the first Battle of Narva. This commemoration is characterised here as a successful local negotiation of a potentially divisive past, as are subsequent commemorations of the Russian conquest of Narva in 1704. A recent proposal to erect a statue of Peter the Great in the city, however, briefly threatened to open a new front in Estonia's ongoing 'war of monuments'. Through a discussion of these episodes, the article seeks to link the Narva case to broader conceptual issues of identity politics, nationalism and post-communist transition

    Sufficient conditions on the Tychonoff spaces X and Y are found that imply that the equation in the title holds. Sufficient conditions on the Tychonoff space X are found that ensure that the equation holds for every Tychonoff space Y . A series of examples (some using rather sophisticated cardinal arithmetic) are given that witness that these results cannot be generalized much

    The extraresolvability of some function spaces

    A space X is said to be extraresolvable if X contains a family D of dense subsets such that the intersection of every two elements of D is nowhere dense and |D| > Δ(X), where Δ(X) = min{|U| : U is a nonempty open subset of X} is the dispersion character of X. In this paper, we study the extraresolvability of some function spaces Cp(X) equipped with the pointwise convergence topology. We show that Cp(X) is not extraresolvable provided that X satisfies one of the following conditions: X is metric; nw(X) = ω; X is normal; e(X) = nw(X) and either e(X) is attained or cf(e(X)) is countable. Hence, Cp(R) and Cp(Q) are not extraresolvable. We establish the equivalences 2ω ω, where [0,κ) has the order topology. We also prove that if κcf(κ) = κ and cf(κ) > ω, then Cp({0,1}κ) is extraresolvable; and that Cp(β(κ)) is extraresolvable, for every infinite cardinal κ with the discrete topology. It is shown that Cp([0,βω1)) is extraresolvable, where βω1 is the beth cardinal corresponding to ω1. Under GCH, for a compact space X, we have that cf(w(X)) > ω iff Cp(X) is extraresolvable. We proved that 2ω < 2ω1 is equivalent to the statement "Cp({0,1}ω1) is strongly extraresolvable"

    PERANCANGAN ARSITEKTUR INFORMASI PT. YUNIA YOGA FARMA BANDUNG MENGGUNAKAN BUSINESS SYSTEM PLANNING (BSP)

    Get PDF
    Arsitektur informasi merupakan suatu kerangka informasi yang meggambarkan aliran-aliran informasi pada suatu organisasi untuk mengintegrasikan sistem informasi satu sama lain menjadi satu kesatuan. Arsitektur informasi dapat memperlihatkan bagaimana informasi dihasilkan dan digunakan oleh organisasi, memperjelas proses bisnis yang terlibat di organisasi, serta menentukan sistem-sistem utama dan keterhubungan antar sistem-sistem tersebut dalam organisasi. Tujuan dari arsitektur di PT. Yunia Yoga Farma adalah agar dapat mengetahui informasi yang dapat memenuhi kebutuhankebutuhan bisnis organisasi. Arsitektur informasi memadukan kebutuhan informasi, komponen sistem informasi, dan teknologi pendukung. Tujuan penelitian ini adalah untuk merancangan arsitektur informasi menggunakan metode Business System Planning (BSP). Business System Planning (BSP) merupakan metodologi dengan tahapan utama yang mengacu pada proses bisnis dan kelas data, karena apabila organisasi menginginkan suatu pengembangan sistem informasi secara mendasar, harus diawali dengan kejelasan alur proses dan aliran data sehingga dalam pemanfaatannya dapat menyediakan dan memprioritaskan informasi bagi masing-masing bagian dalam organisasi. Penelitian dilakukan dengan melakukan studi literatur, dan wawancara yang terkait dengan kebutuhan rancangan arsitektur informasi, dan melakukan analisis sistem kerja yang sedang berjalan di organisasi. Selanjutnya dilakukan tahap-tahap perancangan arsitektur informasi yang dimulai dari mendefinisikan tujuan bisnis sampai mendefinisikan arsitektur informasi. Setelah rancangan arsitektur informasi terbentuk, dilanjutkan dengan merekomendasikan pemanfaatan arsitektur informasi dan teknologi informasi sebagai pendukung untuk membantu proses terbentuknya informasi. Penelitian ini menghasilkan rancangan arsitektur informasi untuk PT. Yunia Yoga Farma Bandung yang digunakan dalam penetapan rekomendasi pengembangan sistem informasi di organisasi terkait.

    Growth regulation of simian and human AIDS-related non-Hodgkin's lymphoma cell lines by TGF-β1 and IL-6

    BACKGROUND: AIDS-related non-Hodgkin's lymphoma (AIDS-NHL) is the second most frequent cancer associated with AIDS, and is a frequent cause of death in HIV-infected individuals. Experimental analysis of AIDS-NHL has been facilitated by the availability of an excellent animal model, i.e., simian Acquired Immunodeficiency Syndrome (SAIDS) in the rhesus macaque consequent to infection with simian immunodeficiency virus. A recent study of SAIDS-NHL demonstrated a lymphoma-derived cell line to be sensitive to the growth inhibitory effects of the ubiquitous cytokine, transforming growth factor-beta (TGF-beta). The authors concluded that TGF-beta acts as a negative growth regulator of the lymphoma-derived cell line and, potentially, as an inhibitory factor in the regulatory network of AIDS-related lymphomagenesis. The present study was conducted to assess whether other SAIDS-NHL and AIDS-NHL cell lines are similarly sensitive to the growth inhibitory effects of TGF-beta, and to test the hypothesis that interleukin-6 (IL-6) may represent a counteracting positive influence in their growth regulation. METHODS: Growth stimulation or inhibition in response to cytokine treatment was quantified using trypan blue exclusion or colorimetric MTT assay. Intracellular flow cytometry was used to analyze the activation of signaling pathways and to examine the expression of anti-apoptotic proteins and distinguishing hallmarks of AIDS-NHL subclass. Apoptosis was quantified by flow cytometric analysis of cell populations with sub-G1 DNA content and by measuring activated caspase-3. RESULTS: Results confirmed the sensitivity of LCL8664, an immunoblastic SAIDS-NHL cell line, to TGF-beta1-mediated growth inhibition, and further demonstrated the partial rescue by simultaneous treatment with IL-6. IL-6 was shown to activate STAT3, even in the presence of TGF-beta1, and thereby to activate proliferative and anti-apoptotic pathways. By comparison, human AIDS-NHL cell lines differed in their responsiveness to TGF-beta1 and IL-6. Analysis of a recently derived AIDS-NHL cell line, UMCL01-101, indicated that it represents immunoblastic AIDS-DLCBL. Like LCL-8664, UMCL01-101 was sensitive to TGF-beta1-mediated inhibition, rescued partially by IL-6, and demonstrated rapid STAT3 activation following IL-6 treatment even in the presence of TGF-beta1. CONCLUSION: These studies indicate that the sensitivity of immunoblastic AIDS- or SAIDS-DLBCL to TGF-beta1-mediated growth inhibition may be overcome through the stimulation of proliferative and anti-apoptotic signals by IL-6, particularly through the rapid activation of STAT3
