Making meaning and meaning making: memory, postmemory and narrative in Holocaust literature

This paper explores links between narration and memory in Holocaust literature and examines ways in which individuals construct memory and postmemory. Based on the premise that ‘All authors mediate reality through their writing...’ and taking into consideration that what we remember and how we remember is likely to have a significant impact on the narratives that we construct, this article considers the reliability of memory. It argues that whilst there is, at times, a blurring of boundaries between fact and fiction in Holocaust literature, this has little or no impact on the validity and authenticity of the narratives. In an attempt to address these issues more fully, this paper explores the notions of making meaning and meaning making, whilst considering the effects of positionality, time and trauma on memory. Key texts referred to in this discussion include Night (1958) by Elie Wiesel, All Rivers Run to the Sea (1996) by Elie Wiesel, In My Brother’s Shadow (2005) by Uwe Timm and The Dark Room (2001) by Rachel Seiffert. These texts have been chosen in order to highlight the subjectivity of memory and postmemory and to demonstrate the role that narrative plays in their construction and representation

Hyperfine transitions of 13CN from pre-protostellar sources

Recent quantum mechanical calculations of rate coefficients for collisional transfer of population between the hyperfine states of 13CN enable their population densities to be determined. We have computed the relative populations of the hyperfine states of the N = 0, 1, 2 rotational states for kinetic temperatures 5 $\le$ T $\le$ 20 K and molecular hydrogen densities 1 $\le$ n(H2) $\le$10 10 cm --3. Spontaneous and induced radiative transitions were taken into account. Our calculations show that, if the lines are optically thin, the populations of the hyperfine states, F, within a given rotational manifold are proportional to their statistical weights, (2F + 1) -- i.e. in local thermodynamic equilibrium -- over the entire range of densities. We have re-analysed IRAM 30 m telescope observations of 13CN hyperfine transitions (N = 1 $\rightarrow$ 0) in four starless cores. A comparison of these observations with our calculations confirms that the hyperfine states are statistically populated in these sources.Comment: MNRAS, Oxford University press, 2015, http://mnras.oxfordjournals.org/content/452/1/19.full?keytype=ref\&ijkey=CCx468pl8lXgoXx. \<10.1093/mnras/stv1322\&gt

Dynamic Euler Diagram Drawing

In this paper we describe a method to lay out a graph enhanced Euler diagram so that it looks similar to a previously drawn graph enhanced Euler diagram. This task is non-trivial when the underlying structures of the diagrams differ. In particular, if a structural change is made to an existing drawn diagram, our work enables the presentation of the new diagram with minor disruption to the user's mental map. As the new diagram can be generated from an abstract representation, its initial embedding may be very different from that of the original. We have developed comparison measures for Euler diagrams, integrated into a multicriteria optimizer, and applied a force model for associated graphs that attempts to move nodes towards their positions in the original layout. To further enhance the usability of the system, the transition between diagrams can be animated

Governing urban wetlands for green growth in the Western Region Megapolis of Sri Lanka

The Western Region Megapolis (WRM) of Sri Lanka, the conurbation associated with Greater Colombo and covering the entire Western Province, is the thriving economic center of the country. According to the State of Sri Lankan Cities 2018 report (GoSL 2018), the city accounts for 40% of Sri Lanka’s gross domestic product (GDP), 30% of its population and is the nation’s administrative center. The WRM is also endowed with wetlands of international importance. This includes the Bellanwila-Attidiya marshes: a 370-ha freshwater marsh in southern Colombo rich in biodiversity (Box 1); the Colombo Flood Detention Area: a 400-ha network of marshes and canals that traverse the DISCUSSION BRIEF An aerial view of the city of Colombo in Sri Lanka with its network of wetlands supporting urban dwellers - A hub for green growth. Photo: Martin Seemungal city; and the Muthurajawela marsh: a 2,500-ha saltwater marsh in northern Colombo, which is the largest saline peat bog in Sri Lanka (IUCN and CEA 2006). The aim of this brief is to support the efforts of the Government of Sri Lanka to leverage the WRM wetlands to foster green growth. Green growth promotes economic development alongside environmental sustainability, and is gaining traction as a model to achieve sustainable urban development globally (Hammer et al. 2011). According to OECD (2013: 9), governments promote green growth “to create jobs and attract firms and investment, while improving local environmental quality and addressing global environmental challenges, particularly climate change.

Coral Reefs, Fisheries, and Food Security: Integrated Approaches to Addressing Multiple Challenges in the Coral Triangle

The Coral Triangle is the most biologically and economically valuable marine ecosystem on the planet. Covering just three percent of the globe, the region represents more than half of the world's reefs and boasts 76 percent of its known coral species. Sustaining more than 130 million people who rely directly on the marine ecosystems for their livelihoods and food, the marine habitats of the Coral Triangle contribute billions of dollars each year toward the economies of the region.Although the environmental imperative for preserving this area of incredible value and biodiversity is obvious, the growing pressures and threats from widespread poverty, rapid development, and global demands continue to place enormous strain on the natural marine resources of the Coral Triangle

Formation Pumping of Molecular Hydrogen in Dark Clouds

Many theoretical and laboratory studies predict H2 to be formed in highly excited ro-vibrational states. The consequent relaxation of excited levels via a cascade of infrared transitions might be observable in emission from suitable interstellar regions. In this work, we model H2 formation pumping in standard dense clouds, taking into account the H/H2 transition zone, through an accurate description of chemistry and radiative transfer. The model includes recent laboratory data on H2 formation, as well as the effects of the interstellar UV field, predicting the populations of gas-phase H2 molecules and their IR emission spectra. Calculations suggest that some vibrationally excited states of H2 might be detectable towards lines of sight where significant destruction of H2 occurs, such as X-ray sources, and provide a possible explanation as to why observational attempts resulted in no detections reported to date.Comment: 32 pages, 8 figures, 5 table

Some Results for Drawing Area Proportional Venn3 With Convex Curves

Many data sets are visualized effectively with area proportional Venn diagrams, where the area of the regions is in proportion to a defined specification. In particular, Venn diagrams with three intersecting curves are considered useful for visualizing data in many applications, including bioscience, ecology and medicine. To ease the understanding of such diagrams, using restricted nice shapes for the curves is considered beneficial. Many research questions on the use of such diagrams are still open. For instance, a general solution to the question of when given area specifications can be represented by Venn3 using convex curves is still unknown. In this paper we study symmetric Venn3 drawn with convex curves and show that there is a symmetric area specification that cannot be represented with such a diagram. In addition, by using symmetric diagrams drawn with polygons, we show that, if area specifications are restricted so that the double intersection areas are no greater than the triple intersection area then the specification can be drawn with convex curves. We also propose a construction that allows the representation of some area specifications when the double intersection areas are greater than the triple intersection area. Finally, we present some open questions on the topic

Drawing Area-Proportional Euler Diagrams Representing Up To Three Sets

Area-proportional Euler diagrams representing three sets are commonly used to visualize the results of medical experiments, business data, and information from other applications where statistical results are best shown using interlinking curves. Currently, there is no tool that will reliably visualize exact area-proportional diagrams for up to three sets. Limited success, in terms of diagram accuracy, has been achieved for a small number of cases, such as Venn-2 and Venn-3 where all intersections between the sets must be represented. Euler diagrams do not have to include all intersections and so permit the visualization of cases where some intersections have a zero value. This paper describes a general, implemented, method for visualizing all 40 Euler-3 diagrams in an area-proportional manner. We provide techniques for generating the curves with circles and convex polygons, analyze the drawability of data with these shapes, and give a mechanism for deciding whether such data can be drawn with circles. For the cases where non-convex curves are necessary, our method draws an appropriate diagram using non-convex polygons. Thus, we are now always able to automatically visualize data for up to three sets

Habitus and Interest in Agroforestry Practices in Missouri

This study analyzes the factors driving interest in two agroforestry practices, riparian buffers and forest farming. Because agroforestry is outside main stream commodity production in US agriculture, the purpose is to evaluate a framework to understand attitudes. The framework incorporates Pierre Bourdieu's notions of "habitus" and "field" along with individual economic and demographic characteristics of farm operators' traditionally used in adoption studies. Four attitudes are analyzed: disengagers, conservatives, lifestyle, and accumulators. A Logit regression measures the effects of respondents' attitudes, and other internal and external factors to assess interest in each practice. The data used is from a household survey of 364 farm-operators from the Fox Wyaconda watershed in northeast Missouri and Scott County in southeast Missouri gathered in 1999. Findings show that a conservative or a lifestyle attitude, are significant, with high probability of being interested in riparian buffers. Those with an accumulator or a lifestyle attitude have a significant and high probability of being interested in forest farming. Other variables also significant in riparian buffer interest are knowledge of agroforestry, and interest in alternative farming practices, and especially having perceptions of erosion problems. In forest farming, a high value of farm and assets has a negative effect, while belonging to informal groups has a positive effect pointing to characteristics that do not belong to traditional farmers.adoption, attitudes, forest farming, habitus, interest, riparian, Institutional and Behavioral Economics,

Temporal evolution of magnetic molecular shocks II. Analytics of the steady state and semi-analytical construction of intermediate ages

In the first paper of this series (Paper I) we computed time dependent simulations of multifluid shocks with chemistry and a transverse magnetic field frozen in the ions, using an adaptive moving grid. In this paper, we present new analytical results on steady-state molecular shocks. Relationships between density and pressure in the neutral fluid are derived for the cold magnetic precursor, hot magnetic precursor, adiabatic shock front, and the following cooling layer. The compression ratio and temperature behind a fully dissociative adiabatic shock is also derived. To prove that these results may even hold for intermediate ages, we design a test to locally characterise the validity of the steady state equations in a time-dependent shock simulation. Applying this tool to the results of Paper I, we show that most of these shocks (all the stable ones) are indeed in a quasi-steady state at all times, i.e. : a given snapshot is composed of one or more truncated steady shock. Finally, we use this property to produce a construction method of any intermediate time of low velocity shocks (u < 20 km/s) with only a steady-state code. In particular, this method allows one to predict the occurrence of steady CJ-type shocks more accurately than previously proposed criteria.Comment: A&A in pres
