Bike share's impact on car use: evidence from the United States, Great Britain, and Australia

Abstract: There are currently more than 700 cities operating bike share programs. Purported benefits of bike share include flexible mobility, physical activity, reduced congestion, emissions and fuel use. Implicit or explicit in the calculation of program benefits are assumptions regarding the modes of travel replaced by bike share journeys. This paper examines the degree to which car trips are replaced by bike share, through an examination of survey and trip data from bike share programs in Melbourne, Brisbane, Washington, D.C., London, and Minneapolis/St. Paul. A secondary and unique component of this analysis examines motor vehicle support services required for bike share fleet rebalancing and maintenance. These two components are then combined to estimate bike share’s overall contribution to changes in vehicle kilometers traveled. The results indicate an estimated reduction in motor vehicle use due to bike share of approx. 90,000 km per annum in Melbourne and Minneapolis/St. Paul and 243,291 km for Washington, D.C. London’s bike share program however recorded an additional 766,341 km in motor vehicle use. This was largely due to a low car mode substitution rate and substantial truck use for rebalancing of bicycles. As bike share programs mature, evaluation of their effectiveness in reducing car use may become increasingly important. Researchers can adapt the analytical approach proposed in this paper to assist in the evaluation of current and future bike share programs.

The walkthrough method: An approach to the study of apps

Abstract: Software applications (apps) are now prevalent in the digital media environment. They are the site of significant sociocultural and economic transformations across many domains, from health and relationships to entertainment and everyday finance. As relatively closed technical systems, apps pose new methodological challenges for sociocultural digital media research. This article describes a method, grounded in a combination of science and technology studies with cultural studies, through which researchers can perform a critical analysis of a given app. The method involves establishing an app’s environment of expected use by identifying and describing its vision, operating model and modes of governance. It then deploys a walkthrough technique to systematically and forensically step through the various stages of app registration and entry, everyday use and discontinuation of use. The walkthrough method establishes a foundational corpus of data upon which can be built a more detailed analysis of an app’s intended purpose, embedded cultural meanings and implied ideal users and uses. The walkthrough also serves as a foundation for further user-centred research that can identify how users resist these arrangements and appropriate app technology for their own purposes.

FT‐Raman and FT‐IR spectroscopic study of synthetic Mg/Zn/Al‐hydrotalcites

Abstract: Synthetic Mg/Zn/Al-hydrotalcites with atomic ratios of 6:0:2, 4:2:2, 2:4:2 and 0:6:2 were characterized by FT-Raman and FT-IR spectroscopy. ‘AlOH’ IR translation modes are observed at 419, 427, 559, 616 and 771 cm−1 with two corresponding Raman bands at 465–477 and 547–553 cm−1. ‘MgOH’ IR translation modes are found at 412, 559 and 616 cm−1 with equivalent Raman bands at 464–477 and 547–553 cm−1. The ‘ZnOH’ IR translation mode is found at 445 cm−1 and the Raman modes around 450 and 495 cm−1. The CO32 − group is identified by the ν1(IR) at 1112 cm−1 and a doublet in the Raman around 1045–1055 and 1060 cm−1. ν2(IR) is observed at 874 cm−1. ν3(IR) is a doublet at 1359 and 1381 cm−1. ν4 is observed in both the IR and Raman spectra around 670 and 695–715 cm−1, respectively. In the OH deformation region, a doublet is observed for ‘AlOH’ at 955 and 1033 cm−1 in the IR spectra. The ‘ZnOH’ IR deformation mode is observed at 1462 cm−1. H2O is characterized by a bending mode at 1632 cm−1 and an H-bonded interlayer H2O mode at 3266 cm−1 with a Raman band between 3244 and 3271 cm−1. The OH stretching region is characterized by three bands in the Raman spectra around 3355–3360, 3440–3455 and 3535–3580 cm−1. One band is observed in the IR spectra at 3471 cm−1.

Examination of gaze behaviors under in situ and video simulation task constraints reveals differences in information pickup for perception and action

Abstract: Queensland University of Technology, Brisbane, Queensland, Australia Gaze and movement behaviors of association football goalkeepers were compared under two video simulation conditions (i.e., verbal and joystick movement responses) and three in situ conditions (i.e., verbal, simplified body movement, and interceptive response). The results showed that the goalkeepers spent more time fixating on information from the penalty kick taker’s movements than ball location for all perceptual judgment conditions involving limited movement (i.e., verbal responses, joystick movement, and simplified body movement). In contrast, an equivalent amount of time was spent fixating on the penalty taker’s relative motions and the ball location for the in situ interception condition, which required the goalkeepers to attempt to make penalty saves. The data suggest that gaze and movement behaviors function differently, depending on the experimental task constraints selected for empirical investigations. These findings highlight the need for research on perceptual— motor behaviors to be conducted in representative experimental conditions to allow appropriate generalization of conclusions to performance environments.
