The institutional and socio-technical determinants of renewable energy production in the EU: implications for policy
Authors: Marra Alessandro , Colantonio Emiliano 
Published: March 2022

AbstractDespite the consensus that the transition to renewable energy is a process that encompasses institutional, regulatory, technical, political, social, and cultural aspects, such issues have rarely been addressed in a comprehensive way. This study explores the determinants of renewable energy production (REP), focusing on institutional and socio-technical aspects. We employ a panel vector autoregressive (PVAR) model to test dynamic relationships for the period 1990–2015 among several variables, as have emerged in the literature: REP, policy stringency, public awareness, lobbying, education, controlling for income and energy imports. Focusing indiscriminately on 18 European Union (EU) member states, the results show that environmental policy stringency does not influence REP, while income and education impact negatively. This evidence is counter-intuitive, and would be surprising if we did not consider the strong heterogeneity between countries. EU member states are engaging in energy transition at different speeds, depending on their individual starting point: this differs from country to country in terms of installed capacity and energy security. Moving from the recent European Green Deal, we divide the sample into two panels based on energy imports to account for different starting points: countries less active on the production side (that depends particularly on energy imports), and countries more active on the production side. Results for the first panel show that an increase in policy stringency would lead to a decrease in lobbying and an increase in REP. Policy efforts must be clearly established and consistently preserved to support REP, at least if there are increasing returns to exploit. Results for the second panel show that lobbying negatively affects the transition to REP, while an increase in public awareness will promote an increase in REP. Therefore, priority should be given to the ‘social’ aspect, and policymakers should increase efforts to reduce the proportion of energy generated from oil, natural gas, coal, and nuclear fuel.

AbstractIntroductionEnabling education programs, otherwise known as Foundation Studies or Preparatory programs, provide pathways for students typically under-represented in higher education. Students in Enabling programs often face distinct challenges in their induction to academic culture which can implicate them in cases of misconduct. This case study addresses a gap in the enabling literature reporting on how a culture of academic integrity can be developed for students and staff in these programs through an educative approach.Case descriptionThis paper outlines how an educative approach to academic integrity is implemented within the Enabling programs of two Australian universities.Discussion and reflectionThis case study reflects upon an approach which makes specific reference to the key elements of ‘support’, ‘approach’ and ‘responsibility’ as highlighted in Bretag and Mahmud’s seminal paper. The paper reports a reduction in misconduct cases at the two institutions suggesting a positive correlation between the interventions and students’ understanding of ethical academic practice. This study reflects upon practitioner experiences with academic integrity investigations to evaluate the effectiveness of this approach.ConclusionsThe authors show that it is possible to ensure academic integrity practices and values are upheld within a supportive learning environment appropriate to a students’ level of study.
A Review of PCN Determination of Airport Pavements Using FWD/HWD Test

Published: March 2022

AbstractAirport pavements are widely constructed as airport runways, taxiways, and aprons. The airport traffic should be considered during the design stage of airport pavements before the construction. To protect airport pavements from negligent overload, a pavement strength rating system and an aircraft load classification system are adopted. Under the rating systems developed by the International Civil Aviation Organization (ICAO), Aircraft Classification Number (ACN) and Pavement Classification Number (PCN) are calculated to assess the aircraft loads and the load-carrying capacity of the airport pavements for unrestricted operations. With the increase in the air transport demand, increasing attention on the continuous evaluation of airport pavement conditions is introduced to airports across the globe. The load-carrying capacity can be evaluated to assess airport pavement conditions by calculating the value of PCN continuously during the service cycle of pavements. The value of PCN can be estimated by testing the response of stationary dynamic loads, adopting a Falling Weight Deflectometer (FWD) or a Heavy Weight Deflectometer (HWD) device that simulates the stress generated by aircraft movements. By evaluating the PCN continuously in Airport Pavement Management System (APMS), cyclic determinations of the load-carrying capacity can be conducted to support the maintenance and rehabilitation (M&R) decision-makers. This review summarizes the methodology for determining the PCN and the tests conducted for evaluating the strength of airport pavement presented in the published literature. Further, the review highlights the benefits of determining PCNs by adopting the FWD or HWD field data with more precise results through mechanistic procedures.

AbstractAdults who had non-edematous severe acute malnutrition (SAM) during infancy (i.e., marasmus) have worse glucose tolerance and beta-cell function than survivors of edematous SAM (i.e., kwashiorkor). We hypothesized that wasting and/or stunting in SAM is associated with lower glucose disposal rate (M) and insulin clearance (MCR) in adulthood.We recruited 40 nondiabetic adult SAM survivors (20 marasmus survivors (MS) and 20 kwashiorkor survivors (KS)) and 13 matched community controls. We performed 150-minute hyperinsulinaemic, euglycaemic clamps to estimate M and MCR. We also measured serum adiponectin, anthropometry, and body composition. Data on wasting (weight-for-height) and stunting (height-for-age) were abstracted from the hospital records.Children with marasmus had lower weight-for-height z-scores (WHZ) (−3.8 ± 0.9 vs. −2.2 ± 1.4; P < 0.001) and lower height-for-age z-scores (HAZ) (−4.6 ± 1.1 vs. −3.4 ± 1.5; P = 0.0092) than those with kwashiorkor. As adults, mean age (SD) of participants was 27.2 (8.1) years; BMI was 23.6 (5.0) kg/m2. SAM survivors and controls had similar body composition. MS and KS and controls had similar M (9.1 ± 3.2; 8.7 ± 4.6; 6.9 ± 2.5 mg.kg−1.min−1 respectively; P = 0.3) and MCR. WHZ and HAZ were not associated with M, MCR or adiponectin even after adjusting for body composition.Wasting and stunting during infancy are not associated with insulin sensitivity and insulin clearance in lean, young, adult survivors of SAM. These data are consistent with the finding that glucose intolerance in malnutrition survivors is mostly due to beta-cell dysfunction.
SAR Altimetry Data as a New Source for Swell Monitoring

Published: March 2022

AbstractThis article shows the first spectral analysis of fully‐focused Synthetic Aperture Radar (FFSAR) altimetry data with the objective of studying backscatter modulations caused by swells. Swell waves distort the backscatter in altimetry radargrams by means of velocity and range bunching. These swell signatures are visible in the tail of the waveform. By locally normalizing the backscatter and projecting the waveforms on an along‐/cross‐track grid, satellite altimetry can be exploited to retrieve swell information. The analysis of FFSAR spectra is supported by buoy‐derived swell‐wave spectra of the National Oceanic and Atmospheric Administration network. Using cases with varying wave characteristics, we discuss the altimetry‐derived spectra and relate them to what is known from side‐looking SAR imaging systems. Besides having a vast amount of additional data for swell‐wave analysis, altimeter data can also help us to better understand the side‐looking SAR spectra.
Peatland Dissolved Organic Carbon Export to Surface Waters: Global Significance and Effects of Anthropogenic Disturbance
Authors: Rosset Thomas , Binet Stéphane , Rigal François , Gandois Laure 
Published: March 2022

AbstractPeatlands are key components of the global carbon cycle. We compiled peatland dissolved organic carbon (DOC) export from 62 sites to provide a global estimate of the contribution of these ecosystems to fluvial organic carbon fluxes. Despite their modest coverage on land (less than 3%), peatlands contribute at least 91 ± 54 Tg DOC to surface waters, and could represent from 12% to 20% of the DOC ultimately transferred to oceans. Boreal peatlands are the main contributors, with 58% of peatland inputs. Tropical peatlands contribute 37% of global peatland fluxes although representing only 13% of global peatland areas. Temperature is the leading factor explaining the variability in DOC fluxes for natural sites, when it is discharge for sites impacted by direct anthropogenic activities. This suggests different trajectories under climate change pressure for non–disturbed and disturbed sites and reinforces the need for hydrological restoration of disturbed peatland sites worldwide.
Differentiating the Causes of Aged Organic Carbon in Marine Sediments

Published: March 2022

AbstractAged organic carbon (OC) is widely observed in surficial sediments deposited on continental margins, resulting from several factors including old OC input and sedimentological processes. While the supply of old OC to marine sediments has been examined and quantified in a range of continent margin settings, there have been few attempts to constrain the extent to which hydrodynamic processes, specifically lateral transport, contribute to the old age of sedimentary OC. Here, we propose a mathematical index, bAgedOC, to differentiate the causes of sedimentary aged OC, and apply this approach to two typical sediment transport pathways that follow the supply and dispersal of terrestrial OC in the marine environment, and further extrapolate it to submarine canyon, Arctic and deep‐sea environments. The index, representing a modification of a widely used quantitative method, provides a novel approach to distinguish the contribution of lateral transport to the pre‐depositional aging of OC in the oceanic region.
Asymmetric Warming/Cooling Response to CO2 Increase/Decrease Mainly Due To Non‐Logarithmic Forcing, Not Feedbacks
Authors: Mitevski Ivan , Polvani Lorenzo M. , Orbe Clara 
Published: March 2022

AbstractWe explore the CO2 dependence of effective climate sensitivity (SG) with symmetric abrupt and transient CO2 forcing, spanning the range 1/8×, 1/4×, 1/2×, 2×, 4×, and 8×CO2, using two state‐of‐the‐art fully coupled atmosphere‐ocean‐sea‐ice‐land models. In both models, under abrupt CO2 forcing, we find an asymmetric response in surface temperature and SG. The surface global warming at 8×CO2 is more than one third larger than the corresponding cooling at 1/8×CO2, and SG is CO2 dependent, increasing non‐monotonically from 1/8×CO2 to 8×CO2. We find similar CO2 dependence in the transient runs, forced with −1%yr−1CO2 and +1%yr−1CO2 up to 1/8×CO2 and 8×CO2, respectively. The non‐logarithmic radiative forcing—not the changing feedbacks—primarily explains the dependence of SG on CO2, particularly at low CO2 levels. The changing feedbacks, however, explain SG's non‐monotonic behavior.
Feedback of Tropical Cyclones Over the Western North Pacific on La Niña Flavor
Authors: Wang Qiuyun , Li Jianping 
Published: March 2022

AbstractThe relationship between La Niña and tropical cyclone (TC) activity has not received as much attention as that between El Niño and TCs; in particular, the important role of TCs in affecting La Niña flavor has not been reported. This study reveals a clear feedback of TCs over the western North Pacific (WNP) on La Niña flavor by modulating the Walker circulation and thermocline. When strong WNP accumulated cyclone energy (ACE) occurs 3 months earlier, the center of sea surface temperature (SST) anomalies shifts to the equatorial eastern Pacific, favoring the development of eastern‐Pacific (EP) La Niña. In contrast, weak WNP ACE is associated with central‐Pacific (CP) La Niña, and the influence of WNP TCs on the intensity of CP La Niña may be larger than for EP La Niña. More evidence is provided in the predictions of EP and CP La Niña events using the ACE + SST model.

Published: March 2022

AbstractIrregular industrial Carbon monoxide (CO) emissions not only deteriorate global atmospheric environment but also add a large uncertainty to CO emission inventory. This work demonstrates the potentiality of the Tropospheric Monitoring Instrument (TROPOMI) data product to derive CO emissions from facility‐level industrial sources. We have demonstrated CO emission estimates of 14 randomly selected facility‐level industrial sources over China with uncertainties of 10%–35% from TROPOMI archive between 2017 and 2020. We found that most of the plumes reveal significantly larger emissions than the registered inventory values. The simplicity of the demonstrated plume quantification method makes it easily applicable everywhere around the globe. This study suggests that future CO satellite constellation can routinely observe point source CO emissions to support environment policy.
A Reference Section Through Fast‐Spread Lower Oceanic Crust, Wadi Gideah, Samail Ophiolite (Sultanate of Oman): Trace Element Systematics and REE Crystallization Temperatures—Implications for Hybrid Crustal Accretion
Authors: Müller Samuel , Garbe‐Schönberg Dieter , Koepke Jürgen , Hoernle Kaj 
Published: March 2022

AbstractOceanic gabbros are the most abundant rocks close to Earth's surface. Here we present new data from a consistent profile through the paleocrust of the Samail Ophiolite (Oman), which is thought to provide the best analog for modern fast‐spreading oceanic crust. Incompatible trace elements of co‐existing plagioclase and clinopyroxene fractionate from the mineral core to rim and up section from layered to foliated to varitextured gabbros. Layered gabbro parental melts correspond to mid‐ocean‐ridge basalts (MORB), and plagioclase Ca# shows a pronounced inverse zonation. Likely, they crystallized in situ from hydrous melts, compositionally buffered by replenishment at equilibrium to MORB and near steady‐state boundary conditions. Further upsection, the compositional variability increases. Foliated gabbro rim and core compositions indicate increased fractionation and disequilibrium to MORB, triggered by open‐system fractional crystallization within a heterogeneous magma plumbing structure, characterized by magma mixing, varying ambient water activities, and boundary conditions. Varitextured gabbros are chemically diverse with parental melts partially more primitive than MORB, suggesting that primitive melts directly reach the axial melt lens (AML). REE‐in‐plagioclase‐clinopyroxene thermometry compared to and supported by anorthite‐in‐plagioclase thermometry reveals a relationship of [°C] = 6.1 ± 0.2 × An + 706 ± 19. Crystallization temperatures of the layered gabbros cover a narrow range of 1216 ± 14°C. Considerable temperature variability of 1077–1231°C is observed further upsection, featuring a thermal minimum within the foliated gabbros. This minimum is assumed to represent a zone where the fractionated descending crystal mushes originating from the AML meet with evolved liquids expelled from deeper crustal levels. Our findings suggest hybrid accretion of fast‐spread crust.
A Framework to Evaluate Convective Aggregation: Examples With Different Microphysics Schemes
Authors: Huang Jin‐De , Wu Chien‐Ming 
Published: March 2022

AbstractThis study introduces a modeling framework to evaluate convective aggregation (CA) under radiative‐convective equilibrium simulations using the vector vorticity equation cloud‐resolving model (VVM) coupled to a mixed‐layer slab ocean. The framework introduces the competing effects between the convection‐sea surface temperature (SST) feedback (CSF) and the moisture‐convection feedback (MCF) by modifying the initial SST gradient and the mixed layer depth. Examples of applying this framework are demonstrated by comparing simulations with different microphysics schemes. The conventional five‐category scheme (VVM‐Lin) and the predicted particle properties scheme (P3) are examined by the matrix formed by these two factors. A clear bifurcation of the aggregated/non‐aggregated states can be identified in both sets of experiments. The change of the bifurcation between two sets of experiments suggests that the P3 experiments tend to develop CA due to the stronger MCF. The budget analysis of spatial frozen moist static energy variance is applied to quantify the stronger MCF in the P3 simulations. Convective systems in P3 simulations develop more organized structures, which enhances MCF and leads to CA. The proposed modeling framework provides a reconciled view of the process‐based evaluation of CA among cloud‐resolving models that use different dynamics and physical parameterizations.
Water Footprint Analysis Under Dual Pressures of Carbon Mitigation and Trade Barrier: A CGE‐Based Study for Yangtze River Economic Belt

Published: March 2022

AbstractFacing the dual pressures of carbon mitigation and trade barrier, it is desired that variations of water footprints (WFs) with the related policy interferences be investigated in Yangtze River Economic Belt (YREB). In this study, a factorial equilibrium WFs model is developed to (a) tackle the interactive effects (on blue‐ and gray‐WFs) of different policy alternatives presented as multiple levels of carbon tax and import tariff; (b) explore the variations of blue‐ and gray‐WFs in specific socio‐economic sectors under multiple scenarios of the dual pressures; and (c) investigate the provincial WFs from the perspective of commodity consumption. It is found that increased import tariffs can boost the WFs of primary energy and resource‐conversion sectors, and can promote inter‐sectoral virtual‐water exchanges; carbon tax can suppress the WFs for most of the sectors, and can result in entirely declined industrial production. Moreover, carbon tax can lead to reduced water productivity in YREB, and thus exacerbate water shortage. Through this research, desired policies for water‐footprint management policies could be identified with maximized socio‐economic and environmental benefits.
Strength and Memory of Precipitation's Control Over Streamflow Across the Conterminous United States

Published: March 2022

AbstractHow precipitation (P) is translated into streamflow (Q) and over what timescales (i.e., “memory”) is difficult to predict without calibration of site‐specific models or using geochemical approaches, posing barriers to prediction in ungauged basins or advancement of general theories. Here, we used a data‐driven approach to identify regional patterns and exogenous controls on P–Q interactions. We applied an information flow analysis, which quantifies uncertainty reduction, to a daily time series of P and Q from 671 watersheds across the conterminous United States. We first demonstrated that information transfer from P to Q primarily reflects the quickflow component of water‐budgets, based on a watershed model. Readily quantifiable information flows show a functional relationship with model parameters, suggesting utility for model calibration. Second, applied to real watersheds, P–Q information flows exhibit seasonally varying behavior within regions in a manner consistent with dominant runoff generation mechanisms. However, the timing and the magnitude of information flows also reflect considerable subregional heterogeneity, likely attributable to differences in watershed size, baseflow contributions, and variation in aerial coverage of preferential flow paths. A regression analysis showed that a combination of climate and watershed characteristics are predictive of P–Q information flows. Though information flows cannot, in most cases, uniquely determine dominant runoff mechanisms, they provide a means to quantify the heterogeneous outcomes of those mechanisms within regions, thereby serving as a benchmarking tool for models developed at the regional scale. Last, information flows characterize regionally specific ways in which catchment connectivity changes from the wet to dry season.
The Universal Eating Monitor (UEM): objective assessment of food intake behavior in the laboratory setting
Authors: Kissileff Harry R. 
Published: March 2022

AbstractThe Universal Eating Monitor was a term used to describe a device used in a laboratory setting that enabled investigators to measure, with the same instrument, the rate of eating either solids or liquids, hence the term “universal”. It consisted of an electronic balance placed in a false panel under a table cloth on which could be placed a food reservoir that contained either solid or liquefied food. The device was created in order to determine whether rates of eating differed in pattern between solid and liquid foods. An acceptable mixture of foods of identical composition that could be served as either solid or blended as a liquid was used to test the hypothesis that eating rate and intake were affected by physical composition. A best-fitting mathematical function (intake was quadratic function of time, with coefficients varying among foods used and experimental conditions), quantified intake rates. The device was used to test a variety of mechanisms underlying food intake control. Eating rates were linear when solid foods were used, but negatively accelerated with liquids. Overall, intake did not differ between solid and liquefied food of identical composition. Satiation on a calorie for calorie basis was different among foods, but physical composition interacted with energy density. Hormones and gastric distension were strong influences on food intake and rate of eating. Individuals with bulimia nervosa and binge eating disorder ate more than individuals without these disturbances. Intake in social and individual contexts was identical, but the rate of eating was slower when two individuals dined together. The eating monitor has been a useful instrument for elucidating controls of food intake and describing eating pathology.
