“Putting The Arts In Their Place”: A Case For Map-Making In Art History, Marco Jalla

Artl@s Bulletin

The use of cartography in art history is less than common. Because of its link to the old artistic geography (Kunstgeographie) once used to defend nationalist issues in Nazi Germany, it fell into disfavor until the 1960s and 1970s, when maps regained some attention from a new generation of art historians. Mapping arts indeed proves to be very useful to visualize and organize large dataset and to formulate new hypotheses, both as a descriptive and a prospective tool. The challenge we proposed to the authors was to use maps for questioning the territorial logics, the centers and peripheries of the …

Visual Contagions, The Art Historian, And The Digital Strategies To Work On Them, Béatrice Joyeux-Prunel

Artl@s Bulletin

How do images and styles spread out over time and place? This article presents how art historians can use digital methods to study “visual contagions”– the visual part of globalization: how images circulate, as material artefacts (paintings, sculptures, engravings, etc.…) or in reproductions (in illustrated periodicals, in photography, or on the internet…), through which channels (cultural, geographical, political…) and according to which visual logics. It sketches the new possibilities offered by deep learning and artificial intelligence algorithms applied to images, to better understand the epidemiology of visual diffusions. This Paper is also an opportunity to assess 10 years of digital …

Film And Video As A Space For Political Expression And Social Critique In Syria, Charlotte Bank

Artl@s Bulletin

This article discusses examples of transgressive artistic production in Syria with a focus on moving images. During the 2000s, a young generation of artists began to experiment with digital video and rethink the role of the artist in society. They sought to develop new aesthetic languages and modes of representation. By examining this production in relation to critical and committed works by earlier generations of artists and filmmakers in Syria, I discuss the possibilities and limits of critical art production in the context of the authoritarian Syrian state.

Illness As Political Metaphor In Modernist Arts In Iran, Katrin Nahidi

Artl@s Bulletin

This article explores a political reading of Iranian modernism and analyses art works through the lens of illness as metaphor. This metaphor first emerged in the discourse of gharbzadegi (westoxification) in the 1960s, when the intellectual Jalal al-e Ahmad likened Iran's adaptation of Western modernity to being infected with a highly contagious disease. This article investigates the visual traces of illness as political metaphor in the works of Jalil Ziapour, Bahman Mohassess, Forough Farrokhzad, and Vincenzo Bianchini, while highlighting how these artists reflected one of the most substantial political discourses of their time.

Mining Maps, Making Meaning: An Interview With Kasia Ozga, Nikoo Paydar

Artl@s Bulletin

In the following interview with Kasia Ozga, the Polish-French-American contemporary artist focuses on her Mapping Aluminum series from 2013-2014, metal relief sculptures that throw light on environmental issues arising from bauxite mining and aluminum processing and smelting. Ozga illuminates how she came to focus on the material aluminum, the context in which she developed the project and selected the mapped sites (the Saint Lawrence River in Massena, NY, the Simandou Mountain Range in Guinea, and Ajka Vezprém County, Hungary), and how borders, cartography and maps figure in her larger body of work.

Tracing The Routes Of Floating Exhibitions: A Fluid Cartography Of Post-War Modernism Around 1956, Laura Bohnenblust

Artl@s Bulletin

This article discusses the phenomenon of floating art exhibitions based on the examples of the Argentinian exposición flotante and the Australian Pacific Loan Exhibition (both 1956). They manifested themselves at the same time as the “second wave of biennials” and can be interpreted as floating national pavilions. Through a spatial analysis of the routes taken across the open ocean, it is shown how the ships’ movements form what can be understood as a ‘negative map’ of canonical art history, oriented around the North Atlantic. This cartographic approach reveals blind spots in art historical research and contributes to the creation of …

Jan Hus: The Life And Death Of A Preacher, Pavel Soukup

Purdue University Press Book Previews

Jan Hus was a late medieval Czech university master and popular preacher who was condemned at the Council of Constance and burned at the stake as a heretic in 1415. Thanks to his contemporary influence and his posthumous fame in the Hussite movement and beyond, Hus has become one of the best known figures of the Czech past and one of the most prominent reformers of medieval Europe as a whole. This definitive biography now available in English opposes the view of Hus that saw his importance primarily as a martyr, subsequently invoked by a variety of religious, national, and …

New Perspectives On Kristallnacht: After 80 Years, The Nazi Pogrom In Global Comparison, Wolf Gruner, Steven J. Ross

Purdue University Press Book Previews

On November 9 and 10, 1938, Nazi leadership unleashed an unprecedented orchestrated wave of violence against Jews in Germany, Austria, and the Sudetenland, supposedly in response to the assassination of a Nazi diplomat by a young Polish Jew, but in reality to force the remaining Jews out of the country. During the pogrom, Stormtroopers, Hitler Youth, and ordinary Germans murdered more than a hundred Jews (many more committed suicide) and ransacked and destroyed thousands of Jewish institutions, synagogues, shops, and homes. Thirty thousand Jews were arrested and sent to Nazi concentration camps.

Virtual Charter Schools And The Democratic Aims Of Education, Dustin Hornbeck, Kathleen Knight Abowitz, Andrew Saultz

Education and Culture

Virtual schooling is expanding as an alternative to traditional public schooling in the early twenty-first century. This paper analyzes virtual schooling with regards to the democratic associational aims of public schooling as conceived by John Dewey. We examine the general landscape of virtual schooling by looking at recent history, governance, and student performance in these schools. Next, we analyze the significant ways in which virtual schools fail to meet associational aims for schooling. We conclude with a normative argument about the nature of new educational trends and innovations, drawing from Dewey’s ideas in The School and Society to articulate the …

Identification Of Novel Adenylyl Cyclase 5 (Ac5) Signaling Networks In D1 And D2 Medium Spiny Neurons Using Bimolecular Fluorescence Complementation Screening, Trevor B. Doyle, Brian S. Muntean, Karin F. Ejendal, Michael P. Hayes, Monica Soto-Velasquez, Kirill A. Martemyanov, Carmen W. Dessauer, Chang-Deng Hu, Val J. Watts

Purdue University Libraries Open Access Publishing Fund

Adenylyl cyclase type 5 (AC5), as the principal isoform expressed in striatal medium spiny neurons (MSNs), is essential for the integration of both stimulatory and inhibitory midbrain signals that initiate from dopaminergic G protein-coupled receptor (GPCR) activation. The spatial and temporal control of cAMP signaling is dependent upon the composition of local regulatory protein networks. However, there is little understanding of how adenylyl cyclase protein interaction networks adapt to the multifarious pressures of integrating acute versus chronic and inhibitory vs. stimulatory receptor signaling in striatal MSNs. Here, we presented the development of a novel bimolecular fluorescence complementation (BiFC)-based protein-protein interaction …

Students aspiring to careers in the themed entertainment and attractions industry have few formal options to learn and demonstrate skills and knowledge specific to the industry. Students have shown initiative in developing extracurricular activities, and industry has reached out to offer “next generation” programs and internships. It still remains problematic for industry employers to select the best qualified students from a large pool of aspirants and for motivated candidates to stand out as highly qualified for these opportunities. The Ryerson Invitational Thrill Design Competition (RITDC) was developed to address this problem. RITDC provides learning experiences and performance evaluation with not …

Pitfalls When Dealing With The Public, Politicians, And Project Developers, Darrin Jacobs

Building Academy Conference

Officials who work in the public sector deal with external pressures from citizens, elected officials, contractors, and developers. These groups are all trying to influence building, planning, and code enforcement officials to make sure that their particular projects are completed on their terms. Sometimes these efforts to influence are outright unethical, other times they are more subtle, but can be just a damaging to a public officials reputations. It’s important for an official who works in the public sector to recognize when they may be entering into dangerous territory and ways to avoid putting themselves in a compromising position.

Experimental Investigation On Capillary Water Absorption In Discrete Planar Cracks, Licheng C. Wang, J. Bao

International Conference on Durability of Concrete Structures

Water movement is responsible for the deterioration of concrete and concrete structures, especially when distributed microcracks exist because cracks can facilitate the ingress of aggressive agents. Experiment was carried out on capillary water absorption by discrete planar cracks to clarify the effect of crack width on the transport speed of water by crack. The granite samples were used to create parallel and smooth cracks with purpose to avoid rehydration of the cement-based materials. Two granite blocks were applied to joint by glue for artificially fabricating a single parallel crack by means of ultra thin steel disc with various thicknesses of …

International Conference on Durability of Concrete Structures

During corrosion distinct types of corrosion products form, composed of different ratios of ferrous ions and oxide, hydroxides. Corrosion products have different physical and mechanical properties, mainly density, resistivity, volume and modulus of elasticity compared to iron. Knowing properties of corrosion products is indispensable for service life modelling of structures and can give valuable insight into the long-term corrosion propagation process. In this study micro-indentation method was used to evaluate mechanical properties of different layers formed during long-term carbonation induced corrosion of steel in concrete. Investigation was performed on three sets of reinforced concrete samples, that underwent corrosion during 50, …

Pore Characteristics And Computed Permeability Of Pastes Subject To Freeze-Thaw Cycles At Very Early Ages By X-Ray Ct, Ya Wei, Zehong Wu, Xiang Gao

International Conference on Durability of Concrete Structures

Freeze-thaw cycling can damage microstructure of concrete and reduce the service life of concrete structures. This is especially detrimental for concrete subject to freeze-thaw cycles at very early-ages, such as within the first few days after constructions. Typical low and high water-to-cement (w/c) ratio pastes are investigated experimentally and numerically in this study. The pastes are subject to freeze-thaw cycles at the age of 1, and 7 days and then sealed-cured to the age of 45 days. The pore size distribution is measured and quantified by X-ray computer tomography (CT) with high resolution. The permeability of the corresponding pastes is …

Surface Treatments For Concrete Under Physical Salt Attack, Mohamed Sakr, Mohamed T. Bassuoni

International Conference on Durability of Concrete Structures

Physical salt attack (PSA) is a key deterioration mechanism for concrete structures in contact with salt-rich media. Yet, procedures and techniques for protecting and repairing concrete affected by PSA are not adequately addressed in the technical literature. Therefore, in this study, three surface coatings of concrete were tested to determine their ability to withstand conditions stimulating to PSA. The treatments were selected to achieve either a single function such as acting as a membrane layer or hydrophobic agent, or combined pore blocking and water repelling functions. Coatings were applied on a concrete mixture typically used for residential foundations in Canada. …

Establishment Of A Numerical Model For Sulfate Attacked Concrete Considering Multi-Factors, Shanshan Qin, Dujian Zou, Jun Jiang, Tiejun Liu

International Conference on Durability of Concrete Structures

Sulfate attack is one of the major durability problems of concrete structures, which is manifested by expansive cracks and deterioration of cement paste. In this study, a numerical model is proposed to predict the process of ionic diffusion into concrete under external sulfate attack. The chemical reaction and diffusion processes are considered in this model. Furthermore, the influence of calcium leaching, chemical activity of multi-ions, temperature and changes in porosity are also taken into account. The initial porosity and tortuosity are assumed to be homogeneous in concrete, and the chemical potential gradient is regarded as the driving force for ions …

An Image-Based Local Homogenization Method To Model Mass Transport At The Steel-Concrete Interface, Zhidong Zhang Dr, Ueli Angst Prof, Alexander Michel Prof, Mads Jensen Dr

International Conference on Durability of Concrete Structures

Mass transport (moisture and ions) at the steel-concrete interface is closely related to corrosion of rebar in reinforced concrete structures. Thus, in the model simulating mass transport, the structure of the steel-concrete interface must be well represented. In this study, an image-based local homogenization method is proposed based on images taken in the scanning electron microscope (SEM) under the backscattered electron (BSE) detector. According to the gray level of the image, porosity can be calculated and then proposed equations are used to associate the transport properties (sorption isotherms, diffusion coefficients and permeability) with porosity. Experimental data of chloride concentration taken …

Modelling Of Capillary Pore Structure Evolution In Portland Cement Pastes Based On Irregular-Shaped Cement Particles, Cheng Liu, Mingzhong Zhang, G Fang, Yun Bai, Y Zhang

International Conference on Durability of Concrete Structures

The pore structure plays a crucial role in durability performance of cement-based materials. However, the pore structure in cement pastes is highly dependent on the initial packing of cement particles and cement hydration process, which seems to be related to the shapes of cement particles. This paper proposed a numerical method to investigate the effect of cement particle shapes on capillary pore structures in cement pastes. In this study, irregular-shaped cement particles with various shapes are generated using a novel central growth model, and then incorporated into CEMHYD3D model to simulate Portland cement hydration. Some home-made programs of determining pore …

Durability Design Based On Serviceability Stage For Corroded Reinforced Concrete Structures, Zhongxiaoping Zhongxiaoping, J Zhu, Cb Yuan, Wl Jin, J Xia

International Conference on Durability of Concrete Structures

After analyzing such factors as the structural durability failure state, environmental load and resistance, the durability limit state equation considering steel corrosion initiation, concrete cover cracking and maximum corrosion-induced damage value is established to meet its durability service life requirements under chloride environment. For three different durability limit states, the design theory of reliability, the partial factors of variables for load and resistance are introduced to reflect the target reliability requirements of structural durability, and subsequently the partial factors expression form of structural durability design is established. According to the principle of the same reliability level for partial factors design …
