How Gender and Age Affect Newscasters' Credibility—An Investigation in Switzerland     

David Weibel Ph.D.  Bartholomäus Wissmath Ph.D.  Rudolf Groner Ph.D. 《广播与电子媒介杂志》2013,57(3):466-484

In an experimental study conducted in Switzerland the effects of newscasters' gender and age on credibility were analyzed using a 2 × 2 × 2 factorial design. Participants (N = 160) evaluated Swiss, German, and Austrian TV news items in terms of credibility of the newscaster and credibility of the message. News items read by female newscasters were perceived as being more credible. In contrast, male newscasters were considered to be more credible persons. Furthermore, a significant interaction between the newscasters' gender and age was observed: Age had no effect on the credibility of the younger newscasters, whereas older male newscasters were perceived as being the most credible.  相似文献

Conservation of a room: A treatment proposal for Mark Rothko's Harvard Murals     

Jens Stenger  Narayan Khandekar  Ramesh Raskar  Santiago Cuellar  Ankit Mohan  Rudolf Gschwind 《文物保护研究》2016,61(6):348-361

A treatment with projected light for Mark Rothko's Harvard Murals (1962) is proposed. The group of five paintings on canvas has changed color due to the presence of a fugitive red pigment and excessive exposure to natural light in a room with large windows. For the conservation of Rothko's Harvard room, it is brought into context within his other commissions and environments. The original color of the works is determined by the digital restoration of contemporary photographs. With a camera projector system a compensation image is calculated that is projected onto the original canvas resulting in a restored color appearance. This approach of inpainting with light is compared with considerations of cleaning and inpainting in conventional conservation treatments. Overall lighting and architecture including the unusual wall color carefully chosen by Rothko play a key role in the treatment of the Mural cycle as an environment.  相似文献   

Comparative analysis of delayed alternation learning in cats,mice, and guinea pigs     

Josef Kessler  Hans J. Markowitsch  Wolfgang Guldin  Rudolf Riess  Monika Pritzel  Maria Streicher  Marcus Kerriou 《Learning & behavior》1980,8(3):457-464

The performance of cats, guinea pigs, and mice in a delayed alternation paradigm was compared both during initial learning and following a 10-day retention interval. The testing situation (a modified T-maze), the length of the delay period (10 sec), and the amount of training per session and per week were kept identical for all three species. The results indicated that (1) animals of all three species acquired the task within similar time spans, (2) a considerable variance was apparent in the performance of individual animals independent of their species, and (3) guinea pigs, as a group, appeared to need a somewhat longer time to acquire delayed alternation than did mice and cats. Relearning of the task following the 10-day interval seemed to follow similar laws in all three species.  相似文献   

On the density of stabilizable plants in the class of unstabilizable plants: The real symmetric disk algebra case     

Rudolf Rupp 《Journal of The Franklin Institute》2009,346(8):784-793

Let A_R denote the set of functions from the disk algebra having real Fourier coefficients. Generalizing a result of Quadrat we show that every unstabilizable multi-input multi-output plant is as close as we want to a stabilizable multi-input multi-output plant in the product topology.  相似文献   

Science and Education in a Totalitarian Regime: The Case of Slovakia     

Sebesta  Juraj  Zajac  Rudolf 《Science & Education》1998,7(3):225-229

In this paper we attempt to reflect on the past period in which we have lived and worked; more specifically to examine the role played by science and science education in the two recent Slovakian totalitarian regimes (1939–1945, 1948–1989).  相似文献   

Restrictive Stochastic Item Selection Methods in Cognitive Diagnostic Computerized Adaptive Testing     

Chun Wang  Hua‐Hua Chang  Alan Huebner 《Journal of Educational Measurement》2011,48(3):255-273

This paper proposes two new item selection methods for cognitive diagnostic computerized adaptive testing: the restrictive progressive method and the restrictive threshold method. They are built upon the posterior weighted Kullback‐Leibler (KL) information index but include additional stochastic components either in the item selection index or in the item selection procedure. Simulation studies show that both methods are successful at simultaneously suppressing overexposed items and increasing the usage of underexposed items. Compared to item selection based upon (1) pure KL information and (2) the Sympson‐Hetter method, the two new methods strike a better balance between item exposure control and measurement accuracy. The two new methods are also compared with Barrada et al.'s (2008) progressive method and proportional method.  相似文献
