When processing a face stimulus, the human visual system tends to strongly integrate its constituent features (eyes, nose, mouth, etc) in a so-called holistic representation. Such feature integration mainly occurs in face-sensitive regions located in bilateral fusiform gyrii. Behavioural studies showed that feature integration relies on the extraction of low spatial frequencies (LSF) while high SF (HSF) underlie more local aspects of feature analysis. Following coarse-to-fine models of vision, we propose that the LSF-driven feature integration is an early and fast stage of face perception, in contrast to the longer-lasting extraction of detailed feature cues in HSF. By means of an event-related fMRI design, the present study investigated the temporal dynamics of face LSF and HSF processing in the network of face-sensitive cortical regions. Faces were flashed at 75, 150, or 300 msec, followed by a Gaussian mask. They were band-pass filtered to preserve low or high SF. At short stimulus durations, face-sensitive regions located in bilateral fusiform gyrii and superior temporal sulci responded more strongly to LSF than HSF faces. At longer durations, the same regions were more active for HSF than LSF faces. This pattern did not replicate for phase-scrambled versions of the stimuli. Taken together our findings suggest that face perception proceeds following a coarse-to-fine scenario, with an early and fast LSF-driven feature integration being relayed by the slower accumulation of HSF local information.

A study containing four experiments provided evidence in favour of assimilation effects in retrospective duration judgments due to temporal expectations. In this study, the participants did not know in advance that they would have to reproduce the duration of a target interval. Temporal expectations were induced prior to the target interval by the repeated presentation of a visually filled interval (the expectancy interval). Both the duration of the expectancy interval and the number of presentations of that interval were varied between subjects. The experiments showed a clear assimilation effect of temporal expectations on reproduced duration, indicated by judged durations strongly resembling the duration of the ex-pectancy interval. This effect increased with the magnitude of the difference between the expectancy interval and the target interval, and with the number of repetitions of the expectancy interval. Results were discussed with reference to Helson’s adaptation-level theory. [less ▲]

Two experiments investigated the effect of encoding two standard intervals on the performance in a temporal generalization task. Previous research has suggested that when individuals compare current time intervals with a standard encoded within both the auditory and the visual modality, they apparently use both the auditorily and the visually encoded standard for comparison so that each interval was compared with a “mixture” of both standard representations. However, the results of this study showed that memory mixing also happened within a pure visual modality. Moreover, it could be shown that the occurrence of memory mixing depended on instructional ambiguity. If in the training phase both standard durations were erroneously declared to be the same, memory mixing did occur in the testing phase. If, however, both standard durations were described as being different, memory mixing was not observed. [less ▲]

Escherichia coli phage phiEco32 encodes two proteins that bind to host RNA polymerase (RNAP): gp79, a novel protein, and gp36, a distant homolog of σ(70) family proteins. Here, we investigated the temporal pattern of phiEco32 and host gene expression during infection. Host transcription shutoff and three distinct bacteriophage temporal gene classes (early, middle, and late) were revealed. A combination of bioinformatic and biochemical approaches allowed identification of phage promoters recognized by a host RNAP holoenzyme containing the σ(70) factor. These promoters are located upstream of early phage genes. A combination of macroarray data, primer extension, and in vitro transcription analyses allowed identification of six promoters recognized by an RNAP holoenzyme containing gp36. These promoters are characterized by a single-consensus element tAATGTAtA and are located upstream of the middle and late phage genes. Curiously, gp79, an inhibitor of host and early phage transcription by σ(70) holoenzyme, activated transcription by the gp36 holoenzyme in vitro. [less ▲]

Analysing independent 1-yr data sets of 10 European superconducting gravimeters (SG) reveals statistically significant temporal variations of M2 tidal parameters. Both common short-term (<2 yr) and long-term (>2 yr) features are identified in all SG time-series but one. The averaged variations of the amplitude factor are about 0.2‰. The path of load vector variations equivalent to the temporal changes of tidal parameters suggests the presence of an 8.85 yr modulation (lunar perigee). The tidal waves having the potential to modulate M2 with this period belong to the 3rd degree constituents. Their amplitude factors turn out to be much closer to body tide model predictions than that of the main 2nd degree M2, which indicates ocean loading for 3rd degree waves to be less prominent than for 2nd degree waves within the M2 group. These two different responses to the loading suggest that the observed modulation is more due to insufficient frequency resolution of limited time-series rather than to time variable loading. Presently, SG gravity time-series are still too short to prove if time variable loading processes are involved too as in case of the annual M2 modulation known to appear for analysis intervals of less than 1 yr. Whatever the variations are caused by, they provide the upper accuracy limit for earth model validation and permit estimating the temporal stability of SG scale factors and assessing the quality of gravity time-series.

Following the terrorist attacks in Paris (November 2015) and Brussels (March 2016), several EU Member States have decided to re-establish border controls or to build walls inside the Schengen Area. Although these decisions are temporary and legally framed by the Schengen code, their extent disrupts the free movement within the Schengen Area, in particular in border areas. While lawyers and economists have analyzed the impacts of this situation, the spatial perspective has remained rather neglected. This exploratory contribution aims to address this gap in the literature by outlining the spatial significance of reintroduced controls for border areas inside the Schengen Area. This contribution firstly undertakes a literature review of the different conceptual tools at hand. These are then compared with a set of exploratory empirical materials. The article focuses more precisely on the Greater Region where France and Germany have reintroduced border controls, thus disrupting in particular daily cross-border flows with Luxembourg and Belgium. The analysis demonstrates that the border acts as a filter, disrupting cross-border flows and cooperation. Also, it sheds some light on the important role played by the ideational perception of the border for practitioners and decision-makers. This contribution concludes by suggesting several paths for a future research agenda. [less ▲]

The paper discusses ten philosophical problems in deontic logic: how to formally represent norms, when a set of norms may be termed `coherent', how to deal with normative conflicts, how contrary-to-duty obligations can be appropriately modeled, how dyadic deontic operators may be redefined to relate to sets of norms instead of preference relations between possible worlds, how various concepts of permission can be accommodated, how meaning postulates and counts-as conditionals can be taken into account, and how sets of norms may be revised and merged. The problems are discussed from the viewpoint of input/output logic as developed by van der Torre Makinson. We argue that norms, not ideality, should take the central position in deontic semantics, and that a semantics that represents norms, as input/output logic does, provides helpful tools for analyzing, clarifying and solving the problems of deontic logic.
