12. An Exploration of the Definition of Data Literacy in the Academic and Public Domains

Author

Ghodoosi, Bahareh, Torrisi-Steele, Geraldine, West, Tracey, and Li, Qinyi

Abstract

There is no single agreed-upon definition of data literacy because expectations of what it means to be data literate varies across contexts. The lack of agreement on a definition of data literacy across contexts is therefore necessary. However, definitions are important. Definitions embody our understanding of concepts and are the foundation for operationalization of concepts. The work reported in the chapter is motivated by the observation that despite no shortage of university graduates, organizations are struggling to find data-literate talent. There is an apparent disconnect between data literacy as taught in the academic domain and data literacy as expected by businesses in the public domain. An exploration of definitions of data literacy in academic and public domains is undertaken to gain insight in why the disconnect exists. A thematic analysis and comparison of definitions in the two domains were conducted. The differences identified provide some broad directions for developing data literacy capabilities in students that better fulfil the needs of business organizations.

Abstract

The optimization analysis of gears in a hybrid transmission is carried out using the micro-modification module in the simulation platform of system analysis software MASTA，aiming at the vibration and noise problems of gear meshing in hybrid transmission. By comparing the transmission error between gears before and after modification and the contact stress nephogram of the tooth surface, the effectiveness of micro-modification based on system analysis software MASTA is verified, which provides a reliable theoretical basis for actual modification. The analysis results show that the transmission error of the gear is obviously reduced after micro-modification, and the contact stress nephogram of the tooth surface has been improved to a great extent, which plays an active role in reducing the vibration and noise of the gear. Finally, the data collection and comparative analysis of vibration and noise of gears in transmission are carried out. The results show that the corresponding box vibration acceleration and gear noise will be significantly improved after the micro-modification of the gear pair.

Abstract

Dimethyl sulfide (DMS), emitted from the oceans, is the most abundant biological source of sulfur to the marine atmosphere. Atmospheric DMS is oxidized to condensable products that form secondary aerosols that affect Earth's radiative balance by scattering solar radiation and serving as cloud condensation nuclei. We report the atmospheric discovery of a previously unquantified DMS oxidation product, hydroperoxymethyl thioformate (HPMTF, HOOCH2SCHO), identified through global-scale airborne observations that demonstrate it to be a major reservoir of marine sulfur. Observationally constrained model results show that more than 30% of oceanic DMS emitted to the atmosphere forms HPMTF. Coincident particle measurements suggest a strong link between HPMTF concentration and new particle formation and growth. Analyses of these observations show that HPMTF chemistry must be included in atmospheric models to improve representation of key linkages between the biogeochemistry of the ocean, marine aerosol formation and growth, and their combined effects on climate.

Abstract

Mercury (Hg) is a contaminant of global concern, and an accurate understanding of its atmospheric fate is needed to assess its risks to humans and ecosystem health. Atmospheric oxidation of Hg is key to the deposition of this toxic metal to the Earth's surface. Short-lived halogens (SLHs) can provide halogen radicals to directly oxidize Hg and perturb the budget of other Hg oxidants (e.g., OH and O3). In addition to known ocean emissions of halogens, recent observational evidence has revealed abundant anthropogenic emissions of SLHs over continental areas. However, the impacts of anthropogenic SLHs emissions on the atmospheric fate of Hg and human exposure to Hg contamination remain unknown. Here, we show that the inclusion of anthropogenic SLHs substantially increased local Hg oxidation and, consequently, deposition in/near Hg continental source regions by up to 20%, thereby decreasing Hg export from source regions to clean environments. Our modeling results indicated that the inclusion of anthropogenic SLHs can lead to higher Hg exposure in/near Hg source regions than estimated in previous assessments, e.g., with increases of 8.7% and 7.5% in China and India, respectively, consequently leading to higher Hg-related human health risks. These results highlight the urgent need for policymakers to reduce local Hg and SLHs emissions. We conclude that the substantial impacts of anthropogenic SLHs emissions should be included in model assessments of the Hg budget and associated health risks at local and global scales.

Abstract

Biomass burning (BB) is a major source of trace gases and particles in the atmosphere, influencing air quality, radiative balance, and climate. Previous studies have mainly focused on the BB emissions of carbon and nitrogen species with less attention on chlorine. Reactive chlorine chemistry has significant effects on atmospheric chemistry and air quality. However, quantitative information on chlorine emissions from BB, particularly the long-term trend and associated atmospheric impacts, is limited both on regional and global scales. Here, we report a long-term (2001–2018) high-resolution BB emission inventory for the major chlorine-containing compounds (HCl, chloride, and CH3Cl) in Asia based on satellite observations. We estimate an average of 730 Gg yr−1 chlorine emitted from BB activity in Asia, with China contributing the largest share at 24.2% (177 Gg yr−1), followed by Myanmar at 18.7% and India at 18.3%. Distinct seasonal patterns and significant spatial and interannual variability are observed, mainly driven by human-mediated changes in agricultural activity. By incorporating the newly developed chlorine emission inventory into a global chemistry-climate model (CAM-Chem), we find that the BB-chlorine emissions lead to elevated levels of HCl and CH3Cl (monthly average up to 2062 and 1421 parts per trillion by volume (pptv), respectively), subsequently resulting in noticeable changes in oxidants (up to 3.1% in O3 and 17% in OH radicals). The results demonstrate that BB is not only a significant source of air pollutants but also of oxidants, suggesting a larger role of BB emissions in the atmospheric chemistry and oxidation process than previously appreciated. In light of the projected increase in BB activity toward the end of the century and the extensive control of anthropogenic emissions worldwide, the contribution of BB emissions may become fundamental to air quality composition in the future.

Abstract

Urban construction is confronted with increasingly complex challenges as social and economic development progresses. Urban regeneration has become an inevitable choice for promoting high-quality urban development in the new era. Historical and cultural districts, with historic buildings as spatial carriers, are microcosms of a city's development and a testimony to the lives of local people. It is necessary to define their development position, role in the city, and functions to revitalize them commercially. The best way to achieve these goals is to clarify consumer preferences and identify the key factors that influence target groups' behavioral preferences in similar shopping areas. Only then will we be able to truly preserve the character and value of heritage districts while promoting their commercial development. This paper focuses on heritage districts. Through a combination of online and offline questionnaires, the authors learned about the current situation of young consumer behavioral preferences for urban commercial revitalization projects. A theory of planned behavior model was then built to empirically analyze the factors influencing consumer behavioral preferences in these projects. Based on the results of our analysis, we propose goals and suggestions for the government, property developers, and citizens involved in revitalization projects to support urban commercial revitalization and promote consumers' consumption intentions. Governments emphasize the importance of culture and give more directions to maintain historical elements. From the perspective of property developers, a business format combining culture and the market is necessary. The participation of citizens in the process of urbanization leads to a people-oriented and sustainable strategy that is beneficial for future development. [ABSTRACT FROM AUTHOR]
