You are What You Wear: Unless You Moved—Effects of Attire and Posture on Person Perception
While first impressions are often based on appearance cues, little is known about how these interact with information from other channels. The present research aimed to investigate the impact of occupational stereotypes, evoked by attire, as well as posture on person perception. For this, computer animation was used to create avatars with different types of attire (nurse, military, casual) and posture (open, closed). In Study 1 (N = 164), participants attributed significantly more empathy to avatars wearing a nurse versus a military uniform or casual outfit. When adding posture as an additional cue, Study 2 (N = 312) showed that ratings of empathy and dominance were affected by both attire and posture. This effect was replicated in Study 3 (N = 163) for female avatars, in the sense that open postures in nurses increased empathy ratings and decreased dominance ratings, which both in turn led to greater perceived competence. By contrast, for male avatars, posture did not affect attributions of competence directly. Rather, attire predicted perceived dominance directly, as well as through perceived empathy. The present findings suggest that both posture, and occupational information evoked by attire, are used to infer personal characteristics. However, the strength of each cue may vary with the gender of the target
Measures and metrics for automatic emotion classification via FACET
For dynamic emotions to be modelled in a natural and
convincing way, systems must rely on accurate affective analysis
of facial expressions in the first place. The present work
introduces two measures for evaluating automatic emotion
classification performance. It further provides a systematic
comparison between 14 databases of dynamic expressions.
Machine analysis was conducted using the FACET system, with
an algorithm calculating recognition sensitivity and confidence.
Results revealed the proportion of facial stimuli that could be
recognised by the machine algorithm above threshold evidence,
showing significant differences in recognition performance
between the databases
Die Bedeutung von Open Innovation in Innovationsnetzwerken : Einblicke in die Automobilindustrie
Die Entwicklung von Innovation wird vermehrt als ein dynamisches Zusammenspiel unterschiedlichster
Akteure angesehen. Steigende Wettbewerbsanforderungen sowie die Gefahr von hohen Flopraten haben in vielen Unternehmen dazu geführt, dass die Anforderungen und Bedürfnisse aktueller und potentieller Kunden detailliert in Form der Kundenintegration analysiert werden. Durch die Einbindung von Kunden in die Innovationsentwicklung wird es Unternehmen möglich, genaue Erkenntnisse über den Kunden zu gewinnen bzw. von dessen Know-how zu rofitieren. Die Tätigkeit von Unternehmen innerhalb von Netzwerken, insbesondere Innovationsnetzwerken, wird in Zukunft einen größeren Einfluss auf die Wettbewerbsfähigkeit von Unternehmen nehmen. Aufgrund dieser Bedeutung der beiden Themenfelder Kundenintegration und Innovationsnetzwerke für die Innovationsentwicklung, stellt sich die Frage, inwieweit eine Integration von Kunden in Innovationsnetzwerke im Verlauf des 21. Jahrhunderts stattfinden wird.
Im Rahmen der vorliegenden Arbeit wird daher anhand einer Literaturanalyse der Forschungsstand der beiden Themenfelder in der wissenschaftlichen Literatur dargestellt. Dies geschieht separat, da bisher diese beiden Forschungsbereiche noch nicht gemeinsam untersucht wurden. Es zeigt sich, dass für die erfolgreiche Tätigkeit innerhalb eines Innovationsnetzwerkes, ein Unternehmen eine Unternehmenskultur der Open Innovation entwickelt. In Bezug auf die Kundenintegration in die Innovationsentwicklung kann sowohl der Zeitpunkt der Einbindung des Kunden, die Intensität dieser Einbindung sowie gewisse Kundenmerkmale als besonders erfolgsrelevant identifiziert werden.
Anhand einer qualitativen Studie wird die Bedeutung der identifizierten erfolgsrelevanten
Dimensionen der Kundenintegration innerhalb von Innovationsnetzwerken aus Unternehmenssicht betrachtet. Hierzu wurden Experten mit Hilfe von direkten Interviews befragt, um in erster Linie qualitative Informationen zum Untersuchungsgegenstand zu erhalten. Ein Vergleich zwischen dem Status Quo der Kundenintegration und der kĂĽnftigen Kundenintegration innerhalb von Innovationsnetzwerken deckt dabei Unterschiede und Gemeinsamkeiten auf. Aufgrund dieser Erkenntnisse werden abschlieĂźend Implikationen fĂĽr die Unternehmenspraxis abgeleitet
Boundary Effects on the Determination of Metamaterial Parameters from Normal Incidence Reflection and Transmission Measurements
A method is described for the determination of the effective electromagnetic
parameters of a metamaterial based only on external measurements or
simulations, taking boundary effects at the interfaces between a conventional
material and metamaterial into account. Plane-wave reflection and transmission
coefficients at the interfaces are regarded as additional unknowns to be
determined, rather than explicitly dependent on the material parameters. Our
technique is thus analogous to the line-reflect-line (LRL) calibration method
in microwave measurements. The refractive index can be determined from
S-parameters for two samples of different thickness. The effective wave
impedance requires the additional assumption that generalized sheet transition
conditions (GSTCs) account for the boundary effects. Expressions for the bulk
permittivity and permeability then follow easily. Our method is validated by
comparison with the results using the Nicolson-Ross-Weir (NRW) for determining
properties of an ordinary material measured in a coaxial line. Utilizing
S-parameters obtained from 3-D full wave simulations, we test the method on
magnetodielectric metamaterials. We compare the results from our method and the
conventional one that does not consider boundary effects. Moreover, it is shown
that results from our method are consistent under changes in reference plane
location, whereas the results from other methods are not.Comment: 16 pages, 16 figures. Submitted to IEEE Transactions on Antennas and

Virtual Clay Modeling using Adaptive Distance Fields
This paper describes an approach for the parametrization and modeling of objects represented by adaptive distance fields (ADFs). ADFs support the construction of powerful solid modeling tools. They can represent surfaces of arbitrary and even changing topology, while providing a more intuitive user interface than control-point based structures such as B-splines. Using the octree structure, an adaptively refined quadrilateral mesh is constructed that is topologically equivalent to the surface. The mesh is then projected onto the surface using multiple projection and smoothing steps. The resulting mesh serves as the ``interface'' for interactive modeling operations and high-quality rendering
