Conrad's impressionism the treatment of space and atmosphere in selected works

This thesis focuses on Conrad's representation of space and atmosphere in the "impressionistic" works published between 1897 and 1904, notably The Nigger of the "Narcissus" (1897), "Heart of Darkness" (1899), Lord Jim (1900), and Nostromo (1904). The many conflicting statements regarding the nature of Conrad's impressionism lead one to ask two fundamental questions: What constitutes this strange and elusive phenomenon, and how does it bear upon interpretation? This thesis works towards defining the elusive quality of Conrad's writing by investigating and assessing the contribution of impressionist techniques in the creation of a pervasive space and atmosphere; secondly, it considers how the various constituent elements interact with, and complement one another to form a dominant mode of fictional space in each work; and, thirdly, it indicates the possible impact that these particular Conradian configurations of space and atmosphere might have upon the interpretation of his impressionist works. The thesis argues that the existential condition of isolatio~experienced by Conrad's heroes and narrators is a consequence of epistemological frustration and fragmentation, which, in turn, is a function of impressionist ontology. There is a definite and complementary relationship between each of these notions in Conrad's fiction. The mysterious atmosphere in his works results from the interplay between various configurations of theme, narration and description, and these novelistic elements correspond roughly with the notions of existential isolation (the dominant theme), epistemology (narrating, telling and (re)telling as a method of knowing and understanding the space in which the characters find themselves) and, lastly, the ontological dimensions of the various modes of fictional space (as realized in description). The evocation and invocation of cosmic space in The Nigger of the "Narcissus," the mapping of a dorriinant symbolic space in "Heart of Darkness," the (re)constructions of Jim's psychological space in Lord Jim, and, finally, the "transcription" and "inscription" of a mythical space in Nostromo, indicate a definite development from epistemological to ontological issues. Phrased in more theoretical terms, this development is a movement from asking predominantly epistemological questions like "How can I interpret this world of which I am a part?" "What is there to be known?" "Who knows it ... and with what degree of certainty?", to asking predominantly ontological questions, such as "Which world is this?" "What kinds of worlds are there ... and how are they constituted?". Such questions, categorized by McHale as the dominant characteristics of Modernist and Postmodernist fiction respectively, are already present in Conrad's texts, thus undermining any clear-cut division between these broad categories. Indeed, this thesis suggests that these categories are at best tenuous, and that they should perhaps be used heuristically, rather than definitivel

Moving Circles: mobile media and playful identities

The mobile phone has become part of our everyday lives with astonishing speed. Over four billion people now have access to mobile phones, and this number keeps increasing. Mobile media technologies shape how we communicate with each other, and relate to the world. This raises questions about their influence on identity. Medium-specific properties and user-practices challenge the idea that we understand ourselves through stories. It is proposed that the notion of play sheds new light on how technologies shape identities. The mobile phone mediates identities on four play levels: we play on the mobile, with the mobile, through the mobile, and at the same time we are played by the mobile. Mobile media bring new freedom of movement. Yet at the same time they constrict us. In this dialectic we become moving circles

Materials and modes of translation: Re-imagining inclusive “zero”-waste futures

In this paper, we present and reflect upon a creative and participatory approach for engaging citizens in imagining desirable “zero”-waste futures that include different values and perspectives. The approach emerged through a 4-month collaboration involving academic researchers and creative professionals and was prototyped in a formerly industrial neighborhood of Utrecht (het Werkspoorkwartier), currently being developed as a creative circular manufacturing area. With our approach, we inquire into and provide an alternative to predominant technology-centered policy visions, which portray the issues of waste as objective challenges that can be addressed through data-driven technological solutions. Such visions neglect many other perspectives and values, particularly those of citizens that face the issue of waste in everyday life, thus providing only a narrow vision of how the future might look like. To gather and articulate different perspectives on alternative “zero”-waste futures, we focus on citizen-science-inspired and speculative design methods to engage people and stimulate imagining futures that bring to light diverse values and perspectives. In the development of the methods, we work in close collaboration with creative practitioners, both in terms of anchoring the research in a real-world context and in terms of combining our different types of expertise. Reflecting on the project, we discuss the potential of our transdisciplinary approach and the co-produced methods to intervene in how we see and imagine alternative futures. We do so by taking “translation” as an analytical lens to understand how different meanings and visions are created through experiential, material, and affective modes of expression. Specifically, we will analyze the translations that occur in the processes of moving from abstract data to matters of concern, and from desirable futures to actionable presents. Looking at these multiple processes through the lens of translation will serve to investigate how different future imaginaries are generated through different materials and modalities of translation, offering different forms of engagement in shaping inclusive urban futures. Translation here will be conceptualized less as a perfect transference of information and more as an open-ended process of paying attention to different values, and identifying those matters for which to care for in our urban futures

Creative Urban Methods for the Datafied City

Dataf ied and smart cities produce some challenges for inclusive, resilient, and sustainable urban futures. How can creative methods contribute to thinking and designing ways to imagine and co-create dataf ied cit-ies with and for participatory citizenship and values for inclusion and sustainability? This question is central to the agenda of the research group [urban interfaces] and their collaboration in interdicisplinary and transdisciplinary partnerships. Working with and around the concepts of participation, criticality and imagination, the group brings cultural inquiry into dataf ied cities together with a methodological inquiry into creative urban methods. In the following, we sketch this agenda and approach and some recent examples of what such creative methods may yield

CyberParks: The interface between people, places and technology

This open access book is about public open spaces, about people, and about the relationship between them and the role of technology in this relationship. It is about different approaches, methods, empirical studies, and concerns about a phenomenon that is increasingly being in the centre of sciences and strategies – the penetration of digital technologies in the urban space. As the main outcome of the CyberParks Project, this book aims at fostering the understanding about the current and future interactions of the nexus people, public spaces and technology. It addresses a wide range of challenges and multidisciplinary perspectives on emerging phenomena related to the penetration of technology in people’s lifestyles - affecting therefore the whole society, and with this, the production and use of public spaces. Cyberparks coined the term cyberpark to describe the mediated public space, that emerging type of urban spaces where nature and cybertechnologies blend together to generate hybrid experiences and enhance quality of life

Controversing Datafication through Media Architectures

In this chapter, we discuss a speculative and participatory “media architecture” installation that engages people with the potential impacts of data through speculative future images of the datafied city. The installation was originally conceived as a physical combination of digital media technologies and architectural form—a “media architecture”—that was to be situated in a particular urban setting. Due to the COVID-19 pandemic, however, it was produced and tested for an online workshop. It is centered on “design frictions” (Forlano and Mathew, 2014) and processes of controversing (Baibarac-Duignan and de Lange, 2021). Instead of smoothing out tensions through “neutral” data visualizations, controversing centers on opening avenues for meaningful participation around frictions and controversies that arise from the datafication of urban life. The installation represents an instance of how processes of controversing may unfold through digital interfaces. Here, we explore its performative potential to “interface” abstract dimensions of datafication, “translate” them into collective issues of concern, and spark imagination around (un)desirable datafied urban futures

Reduction of blood culture contamination rate by an educational intervention

Background: Although mechanical dyssynchrony parameters derived by speckle tracking echocardiography (STE) may predict response to cardiac resynchronization therapy (CRT), comparability of parameters derived with different STE vendors is unknown. Methods: In the MARC study, echocardiographic images of heart failure patients obtained before CRT implantation were prospectively analysed with vendor specific STE software (GE EchoPac and Philips QLAB) and vendor-independent software (TomTec 2DCPA). Response was defined as change in left ventricular (LV) end-systolic volume between examination before and six-months after CRT implantation. Basic longitudinal strain and mechanical dyssynchrony parameters (septal to lateral wall delay (SL-delay), septal systolic rebound stretch (SRSsept), and systolic stretch index (SSI)) were obtained from either separate septal and lateral walls, or total LV apical four chamber. Septal strain patterns were categorized in three types. The coefficient of variation and intra-class correlation coefficient (ICC) were analysed. Dyssynchrony parameters were associated with CRT response using univariate regression analysis and C-statistics. Results: Two-hundred eleven patients were analysed. GE-cohort (n = 123): age 68 years (interquartile range (IQR): 61-73), 67% male, QRS-duration 177ms (IQR: 160-192), LV ejection fraction: 26 +/- 7%. Philips-cohort (n = 88): age 67 years (IQR: 59-74), 60% male, QRS-duration: 179 ms (IQR: 166-193), LV ejection fraction: 27 +/- 8. LV derived peak strain was comparable in the GE-(GE: -7.3 +/- 3.1%, TomTec: -6.4 +/- 2.8%, ICC: 0.723) and Philips-cohort (Philips: -7.7 +/- 2.7%, TomTec: -7.7 +/- 3.3%, ICC: 0.749). SL-delay showed low ICC values (GE vs. TomTec: 0.078 and Philips vs. TomTec: 0.025). ICC's of SRSsept and SSI were higher but only weak (GE vs. TomTec: SRSsept: 0.470, SSI: 0.467) (Philips vs. QLAB: SRSsept: 0.419, SSI: 0.421). Comparability of septal strain patterns was low (Cohen's kappa, GE vs. TomTec: 0.221 and Philips vs. TomTec: 0.279). Septal strain patterns, SRSsept and SSI were associated with changes in LV end-systolic volume for all vendors. SRSsept and SSI had relative varying C-statistic values (range: 0.530-0.705) and different cut-off values between vendors. Conclusions: Although global longitudinal strain analysis showed fair comparability, assessment of dyssynchrony parameters was vendor specific and not applicable outside the context of the implemented platform. While the standardization taskforce took an important step for global peak strain, further standardization of STE is still warranted

Regional sediment deficits in the Dutch lowlands:Implications for long-term land-use options

Background, Aim and Scope. Coastal and river plains are the surfaces of depositional systems, to which sediment input is a parameter of key-importance. Their habitation and economic development usually requires protection with dikes, quays, etc., which are effective in retaining floods but have the side effect of impeding sedimentation in their hinterlands. The flood-protected Dutch lowlands (so-called dike-ring areas) have been sediment-starved for up to about a millennium. In addition to this, peat decomposition and soil compaction, brought about by land drainage, have caused significant land subsidence. Sediment deficiency, defined as the combined effect of sediment-starvation and drainage-induced volume losses, has already been substantial in this area, and it is expected to become urgent in view of the forecasted effects of climate change (sea-level rise, intensified precipitation and run-off). We therefore explore this deficiency, compare it with natural (Holocene) and current human sediment inputs, and discuss it in terms of long-term land-use options. Materials and Methods. We use available 3D geological models to define natural sediment inputs to our study area. Recent progress in large-scale modelling of peat oxidation and compaction enables us to address volume loss associated with these processes. Human sediment inputs are based on published minerals statistics. All results are given as first-order approximations. Results. The current sediment deficit in the diked lowlands of the Netherlands is estimated at 136 ± 67 million m3/a. About 85% of this volume is the hypothetical amount of sediment required to keep up with sea-level rise, and 15% is the effect of land drainage (peat decomposition and compaction). The average Holocene sediment input to our study area (based on a total of 145 km3) is -14 million m3/a, and the maximum (millennium-averaged) input ∼26 million m3/a. Historical sediment deficiency has resulted in an unused sediment accommodation space of about 13.3 km3. Net human input of sediment material currently amounts to ∼23 million m3/a. Discussion. As sedimentary processes in the Dutch lowlands have been retarded, the depositional system's natural resilience to sea-level rise is low, and all that is left to cope is human counter-measure. Preserving some sort of status quo with water management solutions may reach its limits in the foreseeable future. The most viable long-term option therefore seems a combination of allowing for more water in open country (anything from flood-buffer zones to open water) and raising lands that are to be built up (enabling their lasting protection). As to the latter, doubling or tripling the use of filling sand in a planned and sustained effort may resolve up to one half of the Dutch sediment deficiency problems in about a century. Conclusions, Recommendations and Perspectives. We conclude that sediment deficiency - past, present and future - challenges the sustainable habitation of the Dutch lowlands. In order to explore possible solutions, we recommend the development of long-term scenarios for the changing lowland physiography, that include the effects of Global Change, compensation measures, costs and benefits, and the implications for long-term land-use options. © 2007 ecomed publishers (Verlagsgruppe Hüthig Jehle Rehm GmbH)

Probing the Early Stages of Low-Mass Star Formation in LDN 1689N: Dust and Water in IRAS 16293-2422A, B, and E

We present deep images of dust continuum emission at 450, 800, and 850 micron of the dark cloud LDN 1689N which harbors the low-mass young stellar objects (YSOs) IRAS 16293-2422A and B (I16293A and I16293B) and the cold prestellar object I16293E. Toward the positions of I16293A and E we also obtained spectra of CO-isotopomers and deep submillimeter observations of chemically related molecules with high critical densities. To I16293A we report the detection of the HDO 1_01 - 0_00 and H2O 1_10 - 1_01 ground-state transitions as broad self-reversed emission profiles with narrow absorption, and a tentative detection of H2D+ 1_10 - 1_11. To I16293E we detect weak emission of subthermally excited HDO 1_01 - 0_00. Based on this set of submillimeter continuum and line data we model the envelopes around I16293A and E. The density and velocity structure of I16293A is fit by an inside-out collapse model, yielding a sound speed of a=0.7 km/s, an age of t=(0.6--2.5)e4 yr, and a mass of 6.1 Msun. The density in the envelope of I16293E is fit by a radial power law with index -1.0+/-0.2, a mass of 4.4 Msun, and a constant temperature of 16K. These respective models are used to study the chemistry of the envelopes of these pre- and protostellar objects. The [HDO]/[H2O] abundance ratio in the warm inner envelope of I16293A of a few times 1e-4 is comparable to that measured in comets. This supports the idea that the [HDO]/[H2O] ratio is determined in the cold prestellar core phase and conserved throughout the formation process of low-mass stars and planets.Comment: 61 pages, 17 figures.

On-the-fly selection of cell-specific enhancers, genes, miRNAs and proteins across the human body using SlideBase

Genomics consortia have produced large datasets profiling the expression of genes, micro-RNAs, enhancers and more across human tissues or cells. There is a need for intuitive tools to select subsets of such data that is the most relevant for specific studies. To this end, we present SlideBase, a web tool which offers a new way of selecting genes, promoters, enhancers and microRNAs that are preferentially expressed/used in a specified set of cells/tissues, based on the use of interactive sliders. With the help of sliders, SlideBase enables users to define custom expression thresholds for individual cell types/tissues, producing sets of genes, enhancers etc. which satisfy these constraints. Changes in slider settings result in simultaneous changes in the selected sets, updated in real time. SlideBase is linked to major databases from genomics consortia, including FANTOM, GTEx, The Human Protein Atlas and BioGPS. Database URL: http://slidebase.binf.ku.d
