Animal experiments report contradictory findings on the presence of a behavioural and neuronal anisotropy exhibited in vertical and horizontal capabilities of spatial orientation and navigation. We performed a pointing experiment in humans on the imagined 3-D direction of the location of various invisible goals that were distributed horizontally and vertically in a familiar multilevel hospital building. The 21 participants were employees who had worked for years in this building. The hypothesis was that comparison of the experimentally determined directions and the true directions would reveal systematic inaccuracy or dimensional anisotropy of the localizations. The study provides first evidence that the internal representation of a familiar multilevel building was distorted compared to the dimensions of the true building: vertically 215% taller and horizontally 51% shorter. This was not only demonstrated in the mathematical reconstruction of the mental model based on the analysis of the pointing experiments but also by the participants’ drawings of the front view and the ground plan of the building. Thus, in the mental model both planes were altered in different directions: compressed for the horizontal floor plane and stretched for the vertical column plane. This could be related to human anisotropic behavioural performance of horizontal and vertical navigation in such buildings.
Last week, this year’s ISA conference brought together over 5000 scholars and exhibitors from all over the world to discuss all things international, political, scholarly, hold meetings, get lunch together, and party at Mardi Gras (it was in New Orleans, after all!). Similar to last year, a lot of this discussing took also place on Twitter. Scholars-slash-tweeps rallied around the hashtag #isa2015 to talk to each other online about great (and not so great) panels, trends in IR scholarship, gender bias in academia, and (not surprisingly for an academic conference) coffee. Who was most active during ISA2015 on Twitter? What were the most hotly debated topics online? When did ISAlers tweet?
"Je suis Charlie" was used over 619.000 times in the two days that have followed the attack of the editorial team of Charlie Hebdo (Le Progrès, The Huffington Post) and has regularly been taken up in both written and spoken form since. In this paper, we argue that the structure of this sentence actually clashes with its meaning. More specifically, whereas its word order and default rightmost sentence stress are compatible either with an all-focus reading or a narrow focusing of Charlie, the context of use of this sentence as well as the solidarity/empathy message it intends to communicate suggest that its subject is narrowly focused. We will propose that two strategies have emerged to solve this conflict: (i) various alternative forms have appeared that allow proper subject focusing and (ii) speakers have reinterpreted the structure so as to pragmatically retrieve the (additive) focused nature of the subject.
n this paper we analyze an economy with two heterogeneous investors who both exhibit misspecified filtering models for the unobservable expected growth rate of the aggregated dividend. A key result of our analysis with respect to long-run investor survival is that there are degrees of model misspecification on the part of one investor for which there is no compensation by the other investor's deficiency. The main finding with respect to the asset pricing properties of our model is that the two dimensions of asset pricing and survival are basically independent. In scenarios when the investors are more similar with respect to their expected consumption shares, return volatilities can nevertheless be higher than in cases when they are very different.
The Muskoka Initiative – or the Maternal, Newborn and Child Health (MNCH) Initiative has been a flagship foreign policy strategy of the Harper Conservatives since it was introduced in 2010. However, the maternal health initiative has been met with a number of key criticisms in relation to its failure to address the sexual and reproductive health needs of women in the Global South2. In this article, I examine these criticisms and expose the prevalent and problematic discourse employed in Canadian policy papers and official government speeches pertaining to the MNCH Initiative. I examine the embodiment of the MNCH and how these references to women’s bodies as “walking wombs” facilitate: the objectification and ‘othering’ of women as mothers and childbearers; a discourse of ‘saving mothers’ in a paternalistic and essentialist language; and the purposeful omission of gender equality. Feminist International Relations (IR) and post-colonial literature, as well as critical/feminist Canadian foreign policy scholarship are employed in this paper to frame these critiques.
Reading is not only "cold" information processing, but involves affective and aesthetic processes that go far beyond what current models of word recognition, sentence processing, or text comprehension can explain. To investigate such "hot" reading processes, standardized instruments that quantify both psycholinguistic and emotional variables at the sublexical, lexical, inter-, and supralexical levels (e.g., phonological iconicity, word valence, arousal-span, or passage suspense) are necessary. One such instrument, the Berlin Affective Word List (BAWL) has been used in over 50 published studies demonstrating effects of lexical emotional variables on all relevant processing levels (experiential, behavioral, neuronal). In this paper, we first present new data from several BAWL studies. Together, these studies examine various views on affective effects in reading arising from dimensional (e.g., valence) and discrete emotion features (e.g., happiness), or embodied cognition features like smelling. Second, we extend our investigation of the complex issue of affective word processing to words characterized by a mixture of affects. These words entail positive and negative valence, and/or features making them beautiful or ugly. Finally, we discuss tentative neurocognitive models of affective word processing in the light of the present results, raising new issues for future studies.

The production of the hypertriton nuclei 3ΛH and 3Λ¯H¯¯¯¯ has been measured for the first time in Pb-Pb collisions at sNN−−−√ = 2.76 TeV with the ALICE experiment at LHC energies. The total yield, dN/dy ×B.R.(3ΛH→3He,π−)=(3.86±0.77(stat.)±0.68(syst.))×10−5 in the 0-10% most central collisions, is consistent with the predictions from a statistical thermal model using the same temperature as for the light hadrons. The coalescence parameter B3 shows a dependence on the transverse momentum, similar to the B2 of deuterons and the B3 of 3He nuclei. The ratio of yields S3 = 3ΛH/(3He ×Λ/p) was measured to be S3 = 0.60 ± 0.13 (stat.) ± 0.21 (syst.) in 0-10% centrality events; this value is compared to different theoretical models. The measured S3 is fully compatible with thermal model predictions. The measured 3ΛH lifetime, τ=181+54−39(stat.)±33(syst.) ps is compatible within 1σ with the world average value.
The neutron capture cross section of the s-process branch nucleus 63Ni affects the abundances of other nuclei in its region, especially 63Cu and 64Zn. In order to determine the energy-dependent neutron capture cross section in the astrophysical energy region, an experiment at the Los Alamos National Laboratory has been performed using the calorimetric 4πBaF2 array DANCE. The (n,γ) cross section of 63Ni has been determined relative to the well-known 197Au standard with uncertainties below 15%. Various 63Ni resonances have been identified based on the Q value. Furthermore, the s-process sensitivity of the new values was analyzed with the new network calculation tool NETZ.
