Unnatural Narration beyond Postmodernist Alterities

Postmodernism has frequently employed unnatural narration with the aim to disturb and subvert conventionalized reading practices. Postmodernist discourses thus widely associate the unnatural with alterity, marginality and the suppressed. In this paper, I caution against such a perspective, which threatens to unduly limit our understanding of the broad variety of relations between natural and unnatural narrative on the one hand, and of the multiple possible functions of unnatural narratives on the other. Taking my cue from the use of unnatural narration in a number of recent novels, like Mark Z. Danielewski’s House of Leaves (2000), Michael Chabon’s Amazing Adventures of Kavalier & Clay (2000), or Yann Martel’s Life of Pi (2001), I will argue that a postmodernist approach which foregrounds ontological and epistemological questions and emphasizes alterity and subversion remains blind to some of the pragmatic implications that are the main concern of the unnatural narratives under consideration. This not only begs the question whether and in how far such a shift from ontological and epistemological towards pragmatic concerns constitutes a move beyond postmodernism, but also calls for a reconsideration of some of our widely established theories and assumptions about unnatural narratives.

Attention affects prospective memory performance in dichotic listening paradigm

The current study was designed to test for the effect of lateralized attention on prospective memory performance in a dichotic listening task. The practice phase of the experiment consisted of a semantic decision task during which the participants were presented with different words on either side via headphones. Depending on the experimental condition the participants were required to focus on the words presented on the left or right side and to decide if these words were abstract or concrete. Thereafter, the participants were informed about the prospective memory task. They were instructed to press a distinct key whenever they hear a word which denotes an animal in the same task later during the experiment. The participants were explicitly informed that the prospective memory cues could appear on either side of the headphones. This was followed by a retention interval which was filled with unrelated tasks. Next, the participants performed the prospective memory task. The results revealed more prospective hits for the attended side. The finding suggests that noticing a prospective memory cue is not an automatic process but requires attention.

Europeanization in parliament and in the press

Europeanization challenges national democratic systems. As part and parcel of the broader internationalization of politics, Europeanization is associated with a shift from policymaking within majoritarian, elected representative bodies towards technocratic decisions among non-majoritarian and non-elected bodies (Kohler-Koch and Rittberger 2008, Lavenex 2013). It is thus said to weaken the influence of citizens and parliaments on the making of policies and to undermine democratic collective identity (Lavenex 2013, Schimmelfennig 2010). The weakening of national parliaments has been referred to as “de-parliamentarisation” (Goetz and Meyer-Sahling 2008) and has nurtured a broader debate regarding the democratic deficit in the EU. While not being a member of the EU, Switzerland has not remained unaffected by these changes. As discussed in the contribution by Fischer and Sciarini, state executive actors take the lead in Switzerland's European policy. They are responsible for the conduct of international negotiations, they own the treaty making power, and it is up to them to decide whether they wish to launch a negotiation with the EU. In addition, the strong take-it or leave-it character of Europeanized acts limits the room for manoeuver of the parliamentary body also in the ratification phase. Among the public, the rejection of the treaty on the European constitution has definitely closed the era of “permissive consensus” (Hooghe and Marks 2009). However, the process of European unification remains far remote from the European public. In Switzerland, the strongly administrative character of international legislation hinders public discussion (Vögeli 2007). In such a context, the media may serve as cue for the public: By delivering information about the extent and nature of Europeanized policymaking, the media enable citizens to form their own opinions and to hold their representatives accountable. In this sense media coverage may not only be considered an indicator of the information delivered to the public, but it may also enhance the democratic legitimacy of Europeanized policymaking (for a similar argument, see Tresch and Jochum 2005). While the previous contributions to this debate have examined the Europeanization of Swiss (primary and secondary) legislation, we take a closer look at two additional domestic arenas that are both supposed to be under pressure due to Europeanization: The parliament and the media. To that end, we rely on data gathered in a research project that two of us carried out in the context of the NCCR Democracy.1 While this project was primarily interested in the mediatization of decision-making processes in Switzerland, it also investigated the conditional role played by internationalization/Europeanization. For our present purposes, we shall exploit the two data-sets that were developed as part of a study of the political agenda-setting power of the media (Sciarini and Tresch 2012, 2013, Tresch et al. 2013): A data-set on issue attention in parliamentary interventions (initiatives, motions, postulates,2 interpellations and questions) and a data-set on issue attention in articles from the Neue Zürcher Zeitung (NZZ). The data covers the years 1995 to 2003 and the coding of issues followed the classification system developed in the “Policy Agendas Project” (Baumgartner and Jones 1993).

Lateralized processing of faces: The role of features, configurations and familiarity

We investigated the lateralized processing of featural and configural information in face recognition in two divided visual field studies. In Experiment 1, participants matched the identity of a cue face containing either featural (scrambled faces) or configural (blurred faces) information with an intact test face presented subsequently either in the right visual field (RVF) or in the left visual field (LVF). Unilateral presentation was controlled by monitoring eye movements. The results show an advantage of the left hemisphere (LH) over the right hemisphere (RH) for featural processing and a specialization of the RH for configural compared to featural processing. In Experiment 2, we focused on configural processing and its relationship to familiarity. Either learned or novel test faces were presented in the LVF or the RVF. Participants recognized learned faces better when presented in the LVF than in the RVF, suggesting that the RH has an advantage in the recognition of learned faces. Because the recognition of familiar faces relies strongly on configural information (Buttle & Raymond, 2003), we argue that the advantage of the RH over the LH in configural processing is a function of familiarity.

Coded Aperture Flow

Real cameras have a limited depth of field. The resulting defocus blur is a valuable cue for estimating the depth structure of a scene. Using coded apertures, depth can be estimated from a single frame. For optical flow estimation between frames, however, the depth dependent degradation can introduce errors. These errors are most prominent when objects move relative to the focal plane of the camera. We incorporate coded aperture defocus blur into optical flow estimation and allow for piecewise smooth 3D motion of objects. With coded aperture flow, we can establish dense correspondences between pixels in succeeding coded aperture frames. We compare several approaches to compute accurate correspondences for coded aperture images showing objects with arbitrary 3D motion.

Mobile Temporalities: Place, Ruination and the Dialectics of Time

In this chapter I explore the ambiguous, contradictory and often transient ways the past enters into our lives. I shed light on the interplay of mobility and temporality in the lifeworlds of two Somalis who left Mogadishu with the outbreak of the war in the 1990s. Looking into the ways they actively make sense of this crucial ‘memory-place’ (Ricoeur 2004), a place that that has been turned into a landscape of ruins and rubble, alternative understandings of memory and temporality will emerge. Instead of producing a continuum between here and there, and now and then, the stories and photographs discussed in this chapter form dialectical images – images that refuse to be woven into a coherent picture of the past. By emphasising the dialectical ways these two individuals make sense of Mogadishu’s past and presence, I am following Walter Benjamin’s cue to rethink deeply modern analytical categories such as history, memory and temporality by highlighting the brief, fragmented moments of their appearance in everyday life.

Krise, Kritik, Kontingenz: Prolegomena zu einer neuen Poetik der Gemeinschaft

Contingency is the third term that inevitably accompanies crisis and critique. Traditionally, community has been conceived as one of the means to overcome contingency. Taking its cue from the recent work of Roberto Esposito on community and its strategies of immunization, and taking into account that globalization has led to new, contingent forms of community, the essay argues for a new poetics of community conceived as metonymic. The members of a community thus understood share nothing else but the sheer space of their coexistence. Such an approach, I argue, avoids the pitfalls of exclusion that any community conceived of as metaphoric – that is, as sharing a third element – necessarily implies.

Hamlet's Mobility: The Reception of Shakespeare's Tragedy in US-American and Canadian Narrative Fiction

This essay presents a comprehensive study of how Hamlet figures in North American fiction. Gabriele Rippl takes her cue from Stephen Greenblatt’s notion of Shakespeare’s ‘theatrical mobility’ (Greenblatt, Cultural Mobility. Cambridge University Press, 2010). This initial mobility, based on the playwright’s own borrowings, appears to facilitate, or even instigate further migrations. Rippl proceeds to give an overview of adaptations of Shakespeare’s Hamlet in the USA and Canada, thus providing an insight into the historical and cultural uses to which the play has been put by authors such as John Updike or Margaret Atwood. Phenomena such as the ‘republicanization’ of Shakespeare (James Fenimore Cooper), or his appropriation for a feminist counter-discourse in Canada circumscribe a space for the negotiation of cultural and political identities.

Herbivore intoxication as a potential primary function of an inducible volatile plant signal

Plants release herbivore-induced volatiles (HIPVs), which can be used as cues by plants, herbivores and natural enemies. Theory predicts that HIPVs may initially have evolved because of their direct benefits for the emitter and were subsequently adopted as infochemicals. Here, we investigated the potential direct benefits of indole, a major HIPV constituent of many plant species and a key defence priming signal in maize. We used indole-deficient maize mutants and synthetic indole at physiologically relevant doses to document the impact of the volatile on the generalist herbivore Spodoptera littoralis. Our experiments demonstrate that indole directly decreases food consumption, plant damage and survival of S. littoralis caterpillars. Surprisingly, exposure to volatile indole increased caterpillar growth. Furthermore, we show that S. littoralis caterpillars and adults consistently avoid indole-producing plants in olfactometer experiments, feeding assays and oviposition trials. Synthesis. Together, these results provide a potential evolutionary trajectory by which the release of a HIPV as a direct defence precedes its use as a cue by herbivores and an alert signal by plants. Furthermore, our experiments show that the effects of a plant secondary metabolite on weight gain and food consumption can diverge in a counterintuitive manner, which implies that larval growth can be a poor proxy for herbivore fitness and plant resistance.

Spatial proteomic and phospho-proteomic organization in three prototypical cell migration modes

BACKGROUND Tight spatio-temporal signaling of cytoskeletal and adhesion dynamics is required for localized membrane protrusion that drives directed cell migration. Different ensembles of proteins are therefore likely to get recruited and phosphorylated in membrane protrusions in response to specific cues. RESULTS HERE, WE USE AN ASSAY THAT ALLOWS TO BIOCHEMICALLY PURIFY EXTENDING PROTRUSIONS OF CELLS MIGRATING IN RESPONSE TO THREE PROTOTYPICAL RECEPTORS: integrins, recepor tyrosine kinases and G-coupled protein receptors. Using quantitative proteomics and phospho-proteomics approaches, we provide evidence for the existence of cue-specific, spatially distinct protein networks in the different cell migration modes. CONCLUSIONS The integrated analysis of the large-scale experimental data with protein information from databases allows us to understand some emergent properties of spatial regulation of signaling during cell migration. This provides the cell migration community with a large-scale view of the distribution of proteins and phospho-proteins regulating directed cell migration.

Active JNK-dependent secretion of Drosophila Tyrosyl-tRNA synthetase by loser cells recruits haemocytes during cell competition

Cell competition is a process by which the slow dividing cells (losers) are recognized and eliminated from growing tissues. Loser cells are extruded from the epithelium and engulfed by the haemocytes, the Drosophila macrophages. However, how macrophages identify the dying loser cells is unclear. Here we show that apoptotic loser cells secrete Tyrosyl-tRNA synthetase (TyrRS), which is best known as a core component of the translational machinery. Secreted TyrRS is cleaved by matrix metalloproteinases generating MiniTyr and EMAP fragments. EMAP acts as a guiding cue for macrophage migration in the Drosophila larvae, as it attracts the haemocytes to the apoptotic loser cells. JNK signalling and Kish, a component of the secretory pathway, are autonomously required for the active secretion of TyrRS by the loser cells. Altogether, this mechanism guarantees effective removal of unfit cells from the growing tissue.

Effects of stereotypic behaviour and chronic mild stress on judgement bias in laboratory mice

Cognitive processes are influenced by underlying affective states, and tests of cognitive bias have recently been developed to assess the valence of affective states in animals. These tests are based on the fact that individuals in a negative affective state interpret ambiguous stimuli more pessimistically than individuals in a more positive state. Using two strains of mice we explored whether unpredictable chronic mild stress (UCMS) can induce a negative judgement bias and whether variation in the expression of stereotypic behaviour is associated with variation in judgement bias. Sixteen female CD-1 and 16 female C57BL/6 mice were trained on a tactile conditional discrimination test with grade of sandpaper as a cue for differential food rewards. Once they had learned the discrimination, half of the mice were subjected to UCMS for three weeks to induce a negative affective state. Although UCMS induced a reduced preference for the higher value reward in the judgement bias test, it did not affect saccharine preference or hypothalamic–pituitary–adrenal (HPA) activity. However, UCMS affected responses to ambiguous (intermediate) cues in the judgement bias test. While control mice showed a graded response to ambiguous cues, UCMS mice of both strains did not discriminate between ambiguous cues and tended to show shorter latencies to the ambiguous cues and the negative reference cue. UCMS also increased bar-mouthing in CD-1, but not in C57BL/6 mice. Furthermore, mice with higher levels of stereotypic behaviour made more optimistic choices in the judgement bias test. However, no such relationship was found for stereotypic bar-mouthing, highlighting the importance of investigating different types of stereotypic behaviour separately.

The (In)visibility of Psychodiagnosticians' Expertise

This study investigates decision making in mental health care. Specifically, it compares the diagnostic decision outcomes (i.e., the qualityof diagnoses) and the diagnostic decision process (i.e., pre-decisional information acquisition patterns) of novice and experienced clinicalpsychologists. Participants’ eye movements were recorded while they completed diagnostic tasks, classifying mental disorders. In line withprevious research, our findings indicate that diagnosticians’ performance is not related to their clinical experience. Eye-tracking data pro-vide corroborative evidence for this result from the process perspective: experience does not predict changes in cue inspection patterns. Forfuture research into expertise in this domain, it is advisable to track individual differences between clinicians rather than study differenceson the group level.

Relational Memory Is Evident in Eye Movement Behavior despite the Use of Subliminal Testing Methods

While it is generally agreed that perception can occur without awareness, there continues to be debate about the type of representational content that is accessible when awareness is minimized or eliminated. Most investigations that have addressed this issue evaluate access to well-learned representations. Far fewer studies have evaluated whether or not associations encountered just once prior to testing might also be accessed and influence behavior. Here, eye movements were used to examine whether or not memory for studied relationships is evident following the presentation of subliminal cues. Participants (assigned to experimental or control groups) studied scene-face pairs and test trials evaluated implicit and explicit memory for these pairs. Each test trial began with a subliminal scene cue, followed by three visible studied faces. For experimental group participants, one face was the studied associate of the scene (implicit test); for controls none were a match. Subsequently, the Display containing a match was presented to both groups, but now it was preceded by a visible scene cue (explicit test). Eye movements were recorded and recognition Memory responses were made. Participants in the experimental group looked disproportionately at matching faces on implicit test trials and participants from both groups looked disproportionately at matching faces on explicit test trials, even when that face had not been successfully identified as the associate. Critically, implicit memory-based viewing effects seemed not to depend on residual awareness of subliminal scenes cues, as subjective and objective measures indicated that scenes were successfully masked from view. The reported outcomes indicate that memory for studied relationships can be expressed in eye movement behavior without awareness.
