This article synthesizes the insights gained through presentations and discussions at the 2023 IEEE Workshop on Norbert Wiener in the 21st Century (21CW2023), which focused on "The Future of Work in the Age of Automation."Hosted at Purdue University, this interdisciplinary convening of technologists, social scientists, and humanists explored the impacts of automation on labor, drawing on Wiener's legacy of insights as a backdrop to examine the technologically mediated future we face in coming decades. The workshop presented a rare opportunity to reflect critically on these issues at a pivotal moment in human and technological history, and to elicit underappreciated dimensions. Areas of focus include: the qualitative and quantitative losses associated with automation and AI, the impacts automation has for questions about the meaningfulness of work, the challenges we face related to uncertainty and lack of predictability in technological advancement, and the opportunities that exist for centering human values and agency in these conversations. While acknowledging many items for concern in the context of automation in the future of work, such as the domination of economic narratives, a potential loss of qualitative texture, and the neglect of certain issues key to human identity, the authors conclude by offering optimistic visions - or calls - for redefining value and labor, preserving human agency, and embracing creative problem-solving. © 2024 IEEE.

Most of the arsenic (As) removal methods remove the major part of the other ions in water, especially anions which are important for general water quality measures. However, the efficiency of selective removal is decided on the basis of competitive ions and their concentrations, removal capacity and required water quality parameters. To reduce the waste and energy use for water treatment , selective As removal and easy separation of adsorbent materials and produced water is a basic need. Although As removal is efficient, if the material cannot be easily separated, additional energy and high-tech instruments are required, which increase the energy use and cost of the operation. Another major characteristic of a sustainable selective As removal method is regeneration and re-use capability. The number of cycles that can effectively remove As determine the capacity of re-use. With increased re-use capacity, waste generation can be significantly reduced as well as the energy use.

Avoiding floodplain development is critical for limiting flood damage, yet there is little empirical evidence of how local governments effectively avoid floodplain development. We conduct a mixed-methods study to explain how local floodplain management influences floodplain development in New Jersey, a state with high development pressure and flood risk. We find that 85% of towns developed relatively little in the floodplain from 2001 to 2019, and they achieved this with commonplace land use management tools and modest levels of local government capacity. One hundred twenty-six New Jersey towns put none of their new housing in the floodplain 2001-2019. Our findings run counter to common reports of rampant floodplain development requiring legal innovation and capacity-building campaigns and suggest alternative approaches for promoting floodplain avoidance. We find multiple paths to floodplain avoidance, weak support for previously identified drivers, and strong evidence that the keys to avoidance include having a few high-quality tools that are well-implemented, requiring consistency, coordination, and commitment of local officials. The multiple paths and importance of maximum, rather than average, quality might explain the mixed evidence in prior research connecting floodplain management actions and development outcomes. A lack of attention to towns that limit floodplain development impedes our ability to learn from and disseminate their successes. Contrary to our expectations, we show that floodplain avoidance can be and is achieved through routine municipal practices. Our findings underscore the importance of sustained commitment to development management as a core tool for limiting flood risk. © 2024 The Author(s).

Remediation is one method to improve environmental quality. Hydrocarbon components, especially PAHs are toxic and are commonly found in the environment, including in the marine environment in port areas and the activities of the petroleum processing industry. The toxic properties of PAHs can be reduced or even eliminated by destroying the molecular structure. The biodegradation method uses microorganisms as a biodegradator. This study aims to determine the biodegradation performance of a consortium of sponge microsymbiont isolates against PAHs components. The interaction between the suspension of the isolate consortium and the PAHs were tested for 25 days. Biodegradation performance against PAHs was determined using GC-MS and FTIR. The results showed that a consortium of sponge microsymbiont isolates, namely: Sp1.A1, Sp2.B2 and Sp3.B1 could degrade naphthalene, anthracene and pyrene components. The level and performance of the biodegradation of the isolate consortium against naphthalene (23.64 %), anthracene (28.98 %), and pyrene (39.01%). The biodegradation product of the isolate consortium against naphthalene was a carboxylic acid group (Hexadecanoic acid), against anthracene in the form of an aromatic alcohol compound (Phenol) and pyrene, an alcohol group organic compound (Benzenemethanol). The order of biodegradation strength of the isolate consortium against the tested PAHs was: pyrene ˃ anthracene ˃ naphthalene. The degradation of the isolate consortium against the PAHs test material did not show a consistent pattern related to the components of the biodegradation product.

In this work, multi-scale cementitious composites were developed using microcrystalline cellulose (MCC) and sisal fibers as reinforcements. Mechanical performance of plain mortar and reinforced mortar samples containing MCC (0.1, 0.2, 0.4 and 0.6%) and 0.50% sisal fibers (with respect to cement weight) was investigated. The experimental work was carried out by dispersing MCC in water with the help of a non-ionic surfactant (Pluronic F-127) using ultrasonication energy. The aqueous suspensions of MCC were then added to the cement-sand mixture along with sisal fibers. The developed cementitious composites were cured inside water for two different hydration periods, 28 and 56 days. It was observed that the fracture energy of the cementitious composites increased by 95% and 24%, respectively after 28 days and 56 days of hydration using 0.1% MCC and 0.5% sisal fibre. © 2019 Trans Tech Publications Ltd, Switzerland.

Estimating health benefits of reducing fossil fuel use from improved air quality provides important rationales for carbon emissions abatement. Simulating pollution concentration is a crucial step of the estimation, but traditional approaches often rely on complicated chemical transport models that require extensive expertise and computational resources. In this study, we develop a novel and succinct machine learning framework that is able to provide precise and robust annual average fine particle (PM2.5) concentration estimations directly from a high-resolution fossil energy use data set. The accessibility and applicability of this framework show great potentials of machine learning approaches for integrated assessment studies. Applications of the framework with Chinese data reveal highly heterogeneous health benefits of reducing fossil fuel use in different sectors and regions in China with a mean of 34/tCO2and a standard deviation of 84/tCO2. Reducing rural and residential coal use offers the highest co-benefits with a mean of 360/tCO2. Our findings prompt careful policy designs to maximize cost-effectiveness in the transition towards a carbon-neutral energy system. Copyright © 2021, The Authors. All rights reserved.

A time-serial topographic change was performed using two kinds of surveying methods, including direct measurement and indirect remote sensing technology for beach topography surveillance. Compared with reference topographic data, the root mean square error was 0.169 m. From May, 2018 to March, 2019, multi-temporal beach topographic change results indicated that the distance between baseline and shoreline varied in the range of −24.82∼9.58 meter, and weekly variates are −3.16∼0.45 m. The UAV technique can be efficiently used to detect topographic change information in the coastal area.

Material stocks in long-lived products require over half of the annual global resource extraction for their construction and maintenance, and lock in energy use through their technical and geospatial characteristics. A thorough understanding of material stocks is therefore essential to inform sustainable resource use strategies. However, despite substantial advances in material stock research in recent decades, their robust quantification remains challenging and bears considerable uncertainties. We assess the (dis)agreement of material stock estimates from 32 recent studies across global, national, and urban scales, and propose recommendations for future work. Overall, we observe medium to high divergences between studies estimating the same material stocks. For end-use categories that aggregate multiple material stocks (e.g., buildings), most global-level estimates show divergences within 140 %. At the national level, most estimates for the USA diverge by <210 %, while those for China by <550 %. At the urban level, most estimates for Beijing fall within 90 %, and for Vienna, within 70 %. For low-income countries, non-residential buildings, and individual materials, the differences are often substantially higher, highlighting the need for an improved scientific basis for policy and planning. These disparities arise from differences in system boundaries, methodology, data sources, definitions, and lack of data to capture the diversity of material stock types. To robustly inform sustainable resource use strategies, the scientific community and practitioners should systematically assess and report sensitivity and uncertainty, and reduce the latter through transparent documentation, model intercomparisons, consensus and open-access databases, enhanced data collection, and comprehensive quantification of material stocks.

The problem of mixed discrete-continuous task planning for mechanical systems, such as aerial drones or other autonomous units, can often be treated as a sequence of point-to-point trajectories. The minimum time optimal solution between points in the plan is critical not only for the calculation of the trajectory in cases where the goal has to be achieved quickly but also for the feasibility checking of the plan and the planning process itself, especially in the presence of deadlines and temporal constraint. In this work, we address the minimum time problem for a second-order system with quadratic drag, under state (velocity) and control (acceleration) constraints. Closed-form expressions for the trajectory are derived and the optimality is proven using the Pontryagin Maximum Principle. Simulations supporting the results are provided and compared with those of an open source academic optimal control solver.
