Although interviewer observations have potential as auxiliary sources of information on key survey variables, questions about their quality temper enthusiasm for their use in survey estimation and responsive survey design. This study considers the utility of two interviewer observations (household income and household receipt of unemployment benefits) collected in a panel survey: the German Labor Market and Social Security (PASS) study. We find that the ability of the interviewer observations to accurately identify these household features is not as high as that of prior-wave survey reports on these features, but the observations do tend to capture accurate information for households with changing socioeconomic status over time (where prior-wave reports may be inconsistent with current-wave reports). The observations add modest predictive power to models for key survey variables that also include survey reports on related variables in prior waves, but this predictive power may be limited by relatively high error rates and variance in observation quality among interviewers. Finally, estimates based on panel households only improve slightly when including the observations in nonresponse adjustments, which is likely due to the inability of the observations to predict response propensity (given a relatively low attrition rate for the panel households). Implications for practice and directions for future research in this area are discussed in conclusion.
We present a framework for cognitive modeling of esthetic decision making based on dynamic prototypes. Starting point of our work
is empirical evidence which shows that subjects’ initial ratings of attractiveness of objects can be influenced by adapting them to new,
typically more innovative objects. The framework consists of three steps: (1) Estimating an initial prototype from the ratings, (2) adapting
the prototype due to the impact of the new objects, and (3) predicting the attractiveness ratings for subsequently presented object by
their similarity to the adapted prototype. The framework allows representation of prototypes and objects as feature vectors containing
metrical or categorial attributes or as structural representations. Within the framework, a variety of similarity measures and similarity-torating
mappings can be explored to gain more precise insight into the cognitive processes underlying esthetical appreciations. We instantiated
the framework for a first set of data obtained in a psychological experiment. In this experiment subjects rated the attractiveness of
an initial set of chairs which varied in length of the backrest and the saturation of the color. Subjects then were adapted to a new set of
chairs with extreme values on both dimensions. Finally, subjects again rated the initial objects. The framework was instantiated with an
e-function to model the non-linear effects of variations in length and saturation on the judgements. Although there were only 25 data
points per subject, we got satisfying results in predicting the shift of esthetical judgements due to adaptation to novel stimuli.
Facial recognition relies on distinct and parallel types of processing: featural processing focuses on
the individual components of a face (e.g., the shape or the size of the eyes), whereas configural (or
“relational”) processing considers the spatial interrelationships among the single facial components
(e.g., distance of the mouth from the nose). Previous neuroimaging evidence has suggested that
featural and configural processes may rely on different brain circuits. By using rTMS, here we show
for the first time a double dissociation in dorsolateral prefrontal cortex for different aspects of face
processing: in particular, TMS over the left middle frontal gyrus (BA8) selectively disrupted
featural processing, whereas TMS over the right inferior frontal gyrus (BA44) selectively interfered
with configural processing of faces. By establishing a causal link between activation in left and
right prefrontal areas and different modes of face processing, our data extend previous
neuroimaging evidence and may have important implications in the study of face-processing
deficits, such as those manifested in prosopagnosia and autistic spectrum disorders.
In Europa hat der Bau von Moscheen in jüngster Zeit heftige Debatten entfacht. Innerhalb dieses Diskurses ist Architektur zunächst als Träger politischer Botschaften verstanden worden. Im weiteren Kontext der Architekturgeschichte wurde die Gestalt von Moscheen von mehreren Faktoren beeinflusst. So konnte sich eine Architektur-Ikonographie der Moschee herausbilden, aus der wiederum moderne und heutige Moscheebauten Anregungen bezogen haben. Die Entwicklung der Kirchenarchitektur im 20. Jahrhunderts kann als Vergleichsbeispiel dienen, um das Potential einer Debatte über angemessene Architekturformen für einen Islam im heutigen Westen aufzuzeigen.
Der Artikel beschäftigt sich mit der Erklärung des altrussischen Lautwandels, insbesondere im Vokalsystem, und versucht eine Erklärung als "Phänomen der dritten Art" (nach Rudi Keller) für den Jat'-Wandel zu skizzieren. Erstmals werden dabei die Änderungen in der morphologischen Paradigmatik mit in den Blickpunkt genommen.
