The goal of this research was to investigate the social carrying capacity of an urban park in Vienna, Austria. We used a stated choice approach, combined with a referendum style conjoint model. Based on the hypothesis that the perception of crowding is influenced by several factors, digitally calibrated images were generated to depict in a systematic and rigorous manner different visitor number...

During March 4-June 23, 2013, CDC conducted its second annual national paid-media tobacco education campaign encouraging adult smokers to quit. These campaigns, called Tips from Former Smokers (Tips), feature true stories of former smokers living with serious smoking-related diseases. To assess the immediate impact of the 2013 Tips campaign, CDC analyzed the weekly numbers of calls to the natio...

METHODS Mothers participated in 1–3 semistructured interviews of 60–90 minutes, which addressed their experiences and expectations of engagement with PHNs and FVs. 29 interviews were conducted (11 by telephone). Interviewer field notes and client records were also reviewed. Data were analysed using open, selective, and theoretical coding. Checks for data credibility included peer debriefing and...

We prove the normality of the limiting distribution of the coefficients of the q-derangement numbers of type B based on the formula of Foata and Han that contains a parameter z. Setting the parameter z to zero, we are led to the case of ordinary q-derangement numbers. For z = 1, we obtain the normality of the distribution of the coefficients of the usual q-derangement numbers of type B.

This report explores the differences in farm and farmer attributes, marketing and management practices, and economic performance among agritourism farms in Missouri receiving different numbers of visitors 1. This is the second report derived from the Missouri Agritourism Survey, a study conducted in 2009 by the Missouri Department of Agriculture and the University of Missouri Department of Park...

The number of interactions with flower visitor species differs considerably among insect pollinated plants. Knowing the causes for this variation is central to the conservation of single species as well as whole plant /flower visitor communities. Species specific constraints on flower visitor numbers are seldom investigated at the community level. In this study we tested whether flower size par...

Linear stability of double diffusive convection of Darcy-Maxwell fluid with Soret and Dufour effects is investigated. The effects of the Soret and Dufour numbers, Lewis number, relaxation time and solutal Darcy Rayleigh number on the stationary and oscillatory convection are presented graphically. The Dufour number enhances the stability of Darcy-Maxwell fluid for stationary convection while it...
