The effects of repetitive news framing on political opinions over time

This study tests how repeated exposure to the same news frame influences political opinions over time. In a survey experiment (N = 296), we repeatedly exposed participants to the same news frame (at the start of the study, after one day, one week, and two weeks) and measured effects on opinions (at the start, after two weeks, and after six weeks). Participants in a control group were exposed only once and the effect was also traced over time. Results show that repetitive framing leads both to stronger and more persistent effects than single exposure. The persistence effects are most evident for individuals with moderate political knowledge. Our study contributes to a more comprehensive model of framing effects in mass communication experiments

Growth and structure of polycrystalline Cr/Au multilayered thin films

Brückl H, Vancea J, Lecheler R, Reiss G, Hoffmann H. Growth and structure of polycrystalline Cr/Au multilayered thin films. Thin solid films. 1994;250(1-2):56-60.Metallic multilayered thin films have recently been investigated due to their new magnetic and transport properties. The interest here is focussed on the characterization of the interfaces between the layers. The analysis of growth and structure of polycrystalline Cr/Au multilayers is accomplished by two complementary techniques: in situ ultrahigh vacuum scanning tunnelling microscopy and ex situ transmission electron microscopy. The combination of these powerful methods provides detailed information about structural characteristics such as crystallite size, surface roughness and crystallographic orientation. Moreover, conclusions can be drawn on the atomic arrangement and growth mechanism at the Cr-Au interface. The results are supported by semiempirical and theoretical expectations

Experimental and Numerical Investigation of the Flow in a 5-Stage Transonic Compressor Rig

The flow in a 5-stage transonic compressor rig was experimentally and numerically investigated. The rig is geometrically scaled from the front part of an existing heavy duty gas turbine compressor with CDA-blading. At several operating points pressures and temperatures were measured in order to get the performance map of the compressor, radial distributions at vane leading edges and static pressures at vanes and casing. In order to identify shock locations and to get information about the rotor-stator interactions and the flow angles, 3D L2F-measurements were done in the first and second rotor at two speeds. A newly developed double periodic measuring L2F-system was employed in order to analyze the results with respect to up- and downstream effects of both rotors. The experimental data were used for the validation and calibration of two steady 3D multistage Navier -Stokes codes with mixing plane models between the blade rows. With STAGE3D, calculations were mainly done for the first 2 transonic stages in order to compare shock locations, velocities, inlet and outlet flow angles with measurements. Furthermore the code was calibrated, which means, that grid sizes and numerical parameters were adjusted to give the best fit to the experiments while having acceptable calculation times. A set of parameters was found, which will be used for the design of new transonic multistage compressors. However not all flow quantities fit well to the measurements. Mass flow and pressures could not be fulfilled at the same time. The other code used was TRACE-S. A procedure for a fast calculation of the whole performance map for all 9 blade rows together was developed and tested. The shape of the calculated speed lines fit well to the measured ones, but the mass flow is predicted too high at off-design conditions. The reason is a too low calculated loss production which is confirmed by the higher calculated radial total pressure distributions

Issue importance as a moderator of framing effects

A growing amount of research is devoted to the question of which individual and contextual variables enhance, limit, or obliterate news framing effects. However, the fundamental question whether framing effects vary depending on the issue at stake has not been addressed. Based on two experimental studies (total N = 1,821), this article investigates the extent to which framing effects differ in magnitude as well as process, depending on how important an issue is. The studies show that a high-importance issue yields no effects and a low-importance issue large effects. This moderating function of issue importance operates both at the contextual and at the individual levels. The implications for future framing effects research are discussed
