The association between smartphone use, stress, and anxiety: A meta-analytic review

Abstract: Research investigating the various mental, physical, and social effects of smartphone use has proliferated in the previous decade. Two variables of interest in this literature are the levels of anxiety and stress associated with smartphone use. The current meta-analysis aimed to provide the first quantitative review of this literature, as well as determine potential moderators that might influence this relationship. A total of 39 independent samples (N = 21, 736) were used to compute a summary effect size of r = .22, p < .001, CI [.17-.28] indicating a small-to-medium association between smartphone use and stress and anxiety. Significant moderators included the year in which the article was published, as well as whether problematic or nonproblematic phone use was assessed. In addition, studies using validated measures of smartphone use indicated a (nonsignificantly) larger association than studies using nonvalidated measures. Strengths and limitations of the meta-analysis, as well as future directions of research are discussed.

Modeling urban land use change and urban sprawl : Calgary, Alberta, Canada

Abstract: This paper implements a land use classification for the City of Calgary, Alberta, Canada, using an object-oriented approach for six Landsat TM and ETM+ images and simulates the land use pattern in the future using Markov Chain analysis and Cellular Automata analysis based on the interactions between these land uses and the transportation network. Shannon’s Entropy (an urban sprawl index) based on the land use classification results is used to measure urban sprawl. This research proves that an object-oriented approach can produce satisfactory classification results. It reveals the manner in which land use is likely to develop in the future, and demonstrates that urban sprawl continued to grow in Calgary during the years between 1985 and 2001. Such models are useful for providing the building blocks for traditional four-step transportation planning models.

Exploring the advantages and challenges of double-skin façades (DSFs)

Abstract: With the global target to promote energy saving in buildings, various studies draw attention to the role of environmentally benign building envelopes. In this regard, double-skin facades (DSFs) have been proposed as a promising passive building technology to enhance the energy efficiency and improve the indoor thermal comfort at the same time. A comprehensive analysis of the current design of DSFs, and their technical aspects is presented in this paper. Construction characteristics of DSFs are also reported. The impacts of DSFs on the energy efficiency and thermal performance are discussed by looking at measured and simulated performances. Findings confirm that significant benefits result from using DSFs. Finally, research opportunities are outlined for further investigation.
