“…Our PL relation slopes α ′ k are uniformly shallower by 0.05-0.10, although the agreement is again consistent with the uncertainties in the individual estimates. The zero-points and slopes agree with recent studies by Laney & Stobie (1994) 1 and Tanvir (1996). coefficients were expected, because we lacked the true mean effective wavelengths for these filters and had simply set their values to those for the CTIO JHK filters.…”

We develop a statistical method for using multicolor photometry to determine distances using Cepheid variables including the effects of temperature, extinction, and metallicity and apply it to UBVRIJHK photometry of 694 Cepheids in 17 galaxies. We derive homogeneous distance, extinction and uncertainty estimates for four models, starting from the standard extragalactic method and then adding the physical effects of temperature distributions, extinction distributions, requiring positive definite extinctions, and metallicity.While we find general agreement with published distances when we make similar systematic assumptions, there is a clear problem in the standard distances because they require Cepheids with negative extinctions, particularly in low metallicity galaxies, unless the mean LMC extinction exceeds E(B − V ) > ∼ 0.25. The problem can be explained by the physically expected metallicity dependence of the Cepheid distance scale, where metal-poor Cepheids are hotter and fainter than metal-rich Cepheids. For V and I we found that the mean magnitude change is −0.14 ± 0.14 mag/dex and the mean color change is 0.13 ± 0.04 mag/dex, with the change in color dominating the change in distance. The effect on Type Ia supernova estimates of the Hubble constant is dramatic because most were found in the metal poor galaxies with the bluest Cepheids. The Type Ia Multi-color Light Curve Shape (MLCS) method estimate for H 0 formally rises from 69 ± 8 km s −1 Mpc −1 to 80 ± 6 km s −1 Mpc −1 with the metallicity correction.

“…In particular, the standard PL relations (e.g. , Laney & Stobie 1994, Tanvir 1996 determine α ′ k based on the Cepheids in the LMC. In the second class, consisting of the extinction and the distance, we know the state vectors (R k and d k ) and would like to determine the dependent variable (E and µ).…”

“…The effectiveness of this teaching method depends on how relevant the story is to the subject being taught. A case study approach, however, can be used within units or subjects to help students analyse puzzling, unexpected events through subject reasoning (Laney, 2001). …”

“…Role-playing activities are often employed within the format of a simulation (Welton and Mallan, 1996;Laney, 2001;Taylor, 2013). Simulation replicates the essential characteristics of the real world but this teaching method does not attempt to generate a perfect real world model.…”

“…Simulation replicates the essential characteristics of the real world but this teaching method does not attempt to generate a perfect real world model. The method simplifies reality so that the real world can be better understood without overwhelming students with too many complex factors (Laney, 2001). Role-playing is normally incorporated in games.…”

This study examined the use and effect of a role-playing game on learners' ability in information systems audit. The study is based on experimental research. Information systems control and audit case study and video had been developed. A total of 75 graduate students undertaking a Master's degree in accounting participated in the experiment. The findings suggested that the role-playing game did enhance participants' perceived knowledgeability, perceived ability to perform actual tasks, and perceived enjoyment of learning. However, learning only occurred if the lecturer was involved in the game. The lecturer had to instruct and provide guidelines to students to perform information systems audit throughout the game. The study also finds an initial relationship between players' enjoyment and their knowledgeability. In addition, the study indicates the correlation between players' enjoyment and their ability to perform the actual information systems auditing tasks.
