How can heat maps of indexing vocabularies be utilized for information seeking purposes?
The ability to browse an information space in a structured way by exploiting
similarities and dissimilarities between information objects is crucial for
knowledge discovery. Knowledge maps use visualizations to gain insights into
the structure of large-scale information spaces, but are still far away from
being applicable for searching. The paper proposes a use case for enhancing
search term recommendations by heat map visualizations of co-word
relation-ships taken from indexing vocabulary. By contrasting areas of
different "heat" the user is enabled to indicate mainstream areas of the field
in question more easily.Comment: URL workshop proceedings: http://ceur-ws.org/Vol-1311
Assessing Educational Research -- An Information Service for Monitoring a Heterogeneous Research Field
The paper presents a web prototype that visualises different characteristics
of research projects in the heterogeneous domain of educational research. The
concept of the application derives from the project "Monitoring Educational
Research" (MoBi) that aims at identifying and implementing indicators that
adequately describe structural properties and dynamics of the research field.
The prototype enables users to visualise data regarding different indicators,
e.g. "research activity", "funding", "qualification project", "disciplinary
area". Since the application is based on Semantic MediaWikitechnology it
furthermore provides an easily accessible opportunity to collaboratively work
on a database of research projects. Users can jointly and in a semantically
controlled way enter metadata on research projects which are the basis for the
computation and visualisation of indicators.Comment: 8 pages, 10 figures, Libraries in the digital age (LIDA) 2014

Analysis of the Heyd-Scuseria-Ernzerhof density functional parameter space
The Heyd-Scuseria-Ernzerhof (HSE) density functionals are popular for their
ability to improve the accuracy of standard semilocal functionals such as
Perdew-Burke-Ernzerhof (PBE), particularly for semiconductor band gaps. They
also have a reduced computational cost compared to hybrid functionals, which
results from the restriction of Fock exchange calculations to small
inter-electron separations. These functionals are defined by an overall
fraction of Fock exchange and a length scale for exchange screening. We
systematically examine this two-parameter space to assess the performance of
hybrid screened exchange (sX) functionals and to determine a balance between
improving accuracy and reducing the screening length, which can further reduce
computational costs. Three parameter choices emerge as useful: "sX-PBE" is an
approximation to the sX-LDA screened exchange density functionals based on the
local density approximation (LDA); "HSE12" minimizes the overall error over all
tests performed; and "HSE12s" is a range-minimized functional that matches the
overall accuracy of the existing HSE06 parameterization but reduces the Fock
exchange length scale by half. Analysis of the error trends over parameter
space produces useful guidance for future improvement of density functionals.Comment: 11 pages, 7 figures, accepted to the Journal of Chemical Physic
Nihilation of femininity in the battle of looks: a Sartrean reading of Jhumpa Lahiriās āA temporary matterā
The panoptic gaze is vested in with a constitutive impact upon the subjectivity of individuals.
Feminist scholars like Luce Irigaray have charged that the metaphor of vision is intimately
connected with the construction of gender and sexual difference. By pointing to the
masculine logic of Western thought, Irigaray confirms that a womanās entry into a dominant
scopic economy signifies her inevitable confinement to passivity. This essay aims to examine
the sexual politics of metaphors of vision in a literary text that is controversially argued to be
a voice for the subordinated Indian immigrant women in the US. As one of the most
influential schools of thought in Western philosophy, the Sartrean paradigm of sexual
difference is employed to investigate this allegation by identifying the latent binary system at
work in the fiction of Jhumpa Lahiri, who has garnered substantial yet controversial critical
attention over her representations of gender. Specifically, this essay focuses on Lahiriās
prefatory story to her Pulitzer Prize-winning short story collection, Interpreter of Maladies
(2000), to unravel the manner her exercise of vision in this narrative perpetuates the
dichotomies of a male subject and a female object pre-established in the traditional
hierarchies of gender in the West. In this story, Lahiri (un)wittingly privileges masculinity
over femininity and reduces the latter to a typically disgusting Sartrean female body of holes
and slime. Hence, notwithstanding infrequent emasculated images of the male subject, it is
ultimately the masculine that, in the battle of looks between male and female, nihilates the
Other to the state of ābeing-in-itselfā and enjoys supremacy over the feminine
Genetic dissection of NK cell responses
The association of Natural Killer (NK) cell deficiencies with disease susceptibility has established a central role for NK cells in host defence. In this context, genetic approaches have been pivotal in elucidating and characterizing the molecular mechanisms underlying NK cell function. To this end, homozygosity mapping and linkage analysis in humans have identified mutations that impact NK cell function and cause life-threatening diseases. However, several critical restrictions accompany genetic studies in humans. Studying NK cell pathophysiology in a mouse model has therefore proven a useful tool. The relevance of the mouse model is underscored by the similarities that exist between cell-structure-sensing receptors and the downstream signaling that leads to NK cell activation. In this review, we provide an overview of how human and mouse quantitative trait locis (QTLs) have facilitated the identification of genes that modulate NK cell development, recognition, and killing of target cells
