Do zoo visitors come to learn? An internationally comparative,mixed-methods study

Zoo visitors go to see animals, but are they there to learn? This mixed-methods study examines visitor learning from both zoos’ and visitors’ perspectives using qualitative and quantitative data. Five hundred and forty zoo visitor interviews from nine case studies provide insight into visitor intentions, which indicate that the majority of visitors (72%) arrive at zoos with a learning agenda. Over 170 zoos across 48 countries also report, via an online questionnaire, that the majority of their visitors come to learn. In contrast, however, 28 face-to-face zoo education staff interviewed at the nine case study sites suggests a different conclusion. The study also indicates that zoos appear to determine visitors’ intentions through a number of methods, but are most heavily reliant on informal measures with only 15% of zoos using both formal and informal processes. Juxtaposing these findings suggests that zoos’ reliance on informal measures of visitor intentions appears to provide them with a less than accurate picture of their visitors’ learning agendas.     

Leg soft tissue position and velocity data from skin markers can be obtained with good to acceptable reliability following heel impacts

Quantifying soft tissue motion following impact is important in human motion analysis as soft tissues attenuate potentially injurious forces resulting from activities such as running and jumping. This study determined the reliability of leg soft tissue position and velocity following heel impacts. A grid of black dots was applied to the skin of the right leg and foot (n = 20). Dots were automatically detected (ProAnalyst^®) from high-speed records of pendulum and drop impacts. Three trained measurers selected columns of dots on each participant for analysis; one measurer 6 months later. Between- and within-measurer differences in kinematic variables were all relatively small (<0.8 cm for position; <3.7 cm/s for velocity) between-measurers and (<0.5 cm for position; <2.6 cm/s for velocity) within-measurer. Good (coefficients of variation (CV) ≤ 10%) to acceptable (CV > 10% and ≤20%) reliability was shown for 95% of the position measures, with mean CVs of 10% and 11% within-measurers and between-measures, respectively. Velocity measures were less reliable; 40% of the measures showed good to marginal (CV > 20% and ≤30%) reliability. This study established that leg soft tissue position data from skin markers could be obtained with good to acceptable reliability following heel impacts. Velocity data were less reliable but still acceptable in many cases.     

The influence of warning messages on the public's perception of substance use: A theoretical framework

We bring different theories together to develop a theoretical framework that helps to understand how early warning messages about (new) dangerous drugs can influence the public's perception of substance use. We bring together the agenda setting theory, framing theory, dual processing theory, social learning theory, health belief model, theory of planned behavior, and cultivation theory in order to explain how warning messages diffused through the mass media can have an impact on the receivers' perceptions. Based on these insights we construct the Integrated Media Effect Framework (IMFE) that takes into account the role of cultural and structural contexts in the realm of early warning systems (EWS). Ultimately, this framework provides valuable guidelines for conceptualizing EWS and for developing applications by governments.     

Values in Education in a Plural Society

This is the text of a talk given to the first conference of the Cambridgeshire Secondary Educational Trust (CSET) on 8 June 1993. Three sets of values related to the work of the educational system are distinguished (Economic, Religious and Humanistic) and the achievement of a proper balance between them is urged.     

Comparison of Mediated Effects: A Correlation Structure Modeling Approach

A correlation structure modeling method for comparison of mediated effects is outlined. The procedure permits point and interval estimation of differences in mediator effects, and is useful with models postulating 1 or more predictor, intervening, or response variables that may also be latent constructs. The approach allows scale-free evaluation of differences in effects of any explanatory upon criterion variables transmitted via studied mediators, and is applied on data from a study of older adults with recent vision loss.
