Ministerial Mandate Letters and Co-ordination in the Canadian Executive
Authors: Ie Kenny William 
Published: December 2023

AbstractPrime ministers in parliamentary systems confront a challenging agency problem in leading cabinets toward cross-government priorities: ministers tend to prioritize departmental interests and may lack incentives and/or information enabling co-ordinated effort. In Canada, a novel mechanism for both increasing incentives and information provision has been developed in recent decades: the mandate letter. These letters are issued by Canadian prime ministers to their ministers, reinforcing government priorities, each minister's responsibilities, and specific policy expectations. This article examines mandate letters as mechanisms inducing interministerial policy co-ordination, focusing on the 2015–2021 period, under Justin Trudeau, as the first Canadian prime minister to release these letters publicly. Using topic modelling and social network analysis, I find that Trudeau has increasingly sought to strengthen ministerial co-ordination and ministers’ focus on crosscutting policy priorities. This case study contributes to our understanding of intraexecutive co-ordination and the agency problem in cabinet government.
Similarity and difference in large-scale functional network alternations between behavioral addictions and substance use disorder: a comparative meta-analysis

AbstractBehavioral addiction (BA) and substance use disorder (SUD) share similarities and differences in clinical symptoms, cognitive functions, and behavioral attributes. However, little is known about whether and how functional networks in the human brain manifest commonalities and differences between BA and SUD. Voxel-wise meta-analyses of resting-state functional connectivity (rs-FC) were conducted in BA and SUD separately, followed by quantitative conjunction analyses to identify the common and distinct alterations across both the BA and SUD groups. A total of 92 datasets with 2444 addicted patients and 2712 healthy controls (HCs) were eligible for the meta-analysis. Our findings demonstrated that BA and SUD exhibited common alterations in rs-FC between frontoparietal network (FPN) and other high-level neurocognitive networks (i.e. default mode network (DMN), affective network (AN), and salience network (SN)) as well as hyperconnectivity between SN seeds and the Rolandic operculum in SSN. In addition, compared with BA, SUD exhibited several distinct within- and between-network rs-FC alterations mainly involved in the DMN and FPN. Further, altered within- and between-network rs-FC showed significant association with clinical characteristics such as the severity of addiction in BA and duration of substance usage in SUD. The common rs-FC alterations in BA and SUD exhibited the relationship with consistent aberrant behaviors in both addiction groups, such as impaired inhibition control and salience attribution. By contrast, the distinct rs-FC alterations might suggest specific substance effects on the brain neural transmitter systems in SUD.
Exploiting the deep seabed for the benefit of humankind: A universal ideology for sustainable resource development or a false necessity?
Authors: Roland Holst Rozemarijn J. 
Published: December 2023

AbstractA pivotal point in time has been reached in the ongoing negotiations under the auspices of the International Seabed Authority (ISA) towards the adoption of regulations for the commercial exploitation of mineral resources in the deep seabed beyond national jurisdiction. The ISA has a mandate to ensure that activities in the Area, legally designated as ‘common heritage of humankind’, are carried out for the benefit of humankind as a whole. Yet, there is a growing sense of unease with the potential imminence of the commercial exploitation phase, and concern that the implementation of all components of the common heritage principle, including its environmental and distributive ambitions, will be compromised in the interest of a handful of industry stakeholders. This article dives under the surface of these tensions by asking how the public interest in a global commons can become constructed in a way that conflates diverse and opposing interests in favour of value extraction by the private sector, revealing the ambivalent role of international law in the process. It uses the concept of ‘false necessity’ to question the apparent urgency and inevitability of commercial exploitation, more specifically to the extent it obscures and pre-empts more inclusive conceptions of ‘benefit’ for humankind. By shifting the focus from the much-debated risks of deep seabed mining to the notion of benefit, the article illuminates the inherent contradictions and distributional asymmetries obscured by the conflated yet purportedly universal conception of public interest in exploitation.
The ‘ideal victim’: A cage for victims’ narratives at the International Criminal Court
Authors: Cuppini Alessandra 
Published: December 2023

AbstractDespite Article 68(3) of the Rome Statute of the International Criminal Court (ICC) granting victims an autonomous standing in proceedings, victims’ participatory rights have often been tailored to fit within the retributive structure of the trials. This contribution aims to provide a different perspective on victims’ role and their narratives in proceedings at the ICC, building upon the expressivist model of international criminal justice and focusing on a specific strand that engages with the adjudication process’s performative and communicative features. In providing a better understanding of how victims’ narrative unfolds in trials at the ICC, the article addresses two issues: how the concept of the victim is constructed at the ICC; and whether and, eventually, how this construct impedes progress in recognizing their narratives in proceedings at the ICC. Concerning the first issue, drawing on criminologist Nils Christie’s theorizing of the ‘ideal victim’, it will be observed that the construct of victims in proceedings at the ICC reflects three main attributes: weakness; innocence; and dependency. The second issue shed light on the extent to which the emphasis on the ‘ideal victim’ can serve as a tool in the hands of institutional actors at the ICC to pre-empt, constrain and subordinate victims’ narratives, in a manner that oversimplifies victimhood. To impose a particular narrative upon victims’ experiences, three main procedural mechanisms have been identified: appropriation of victims’ interests; legal representation of abstract victimhood; and exclusion from the trial of victims who do not conform to the ideal victim.

Published: December 2023

SummaryOocyte cytoplasmic evaluation is based on homogeneity and granular appearance. Our study investigated if a granular cytoplasm, highly heterogeneous, would affect oocyte competence in bovine. In two experiments, bovine cumulus–oocyte complexes (COCs) with homogeneous cytoplasm (control, CC) and granulated cytoplasm (granular, GC) were selected from a regular pool of COCs. Experiment 1 was performed with slaughterhouse ovaries, and Experiment 2 was carried out in Girolando COCs obtained from ovum pick-up. Granular oocytes had higher caspase 3 levels (66.17 ± 11.61 vs 172.08 ± 16.95, P < 0.01) and similar GAP junction activity (5.64 ± 0.45 vs 6.29 ± 0.29). ZAR1 relative mRNA amount was lower in granular oocytes (178.27 ± 151.63 vs 0.89 ± 0.89, P = 0.01) and no effect was detected for MATER, PPP2R1A, ENY2, IGF2R, and BMP15 genes. Despite molecular differences, no detrimental effect was detected on oocyte competence in GC oocytes. Cleavage (Experiment 1: 59.52 ± 7.21% vs 59.79 ± 6.10% and Experiment 2: 68.88 ± 4.82 vs 74.41 ± 5.89%) and blastocyst (Experiment 1: 29.28 ± 4.14% vs 23.15 ± 2.96% and Experiment 2: 21.11 ± 3.28% vs 21.02 ± 6.08%) rates were similar between CC and GC (Experiments 1 and 2, respectively). Post-transfer embryo development revealed that pregnancy (CC: 24.27 ± 9.70% vs GC: 26.31 ± 7.23%) and calving (23.68% vs 33.33%) rates and fetal growth were not affected by the presence of cytoplasmic granules. Our results demonstrated that oocytes with granular cytoplasm present equivalent efficiency for IVF and calf production compared with homogenous cytoplasm oocytes. This could be observed through similar cleavage, blastocyst rates, and fetal growth development. In addition to differences in oocyte gene expression related to oocyte quality, it seems not to affect oocyte developmental competence.
House prices and rents: a reappraisal
Authors: Achou Bertrand , d’Albis Hippolyte , Iliopulos Eleni 
Published: December 2023

AbstractIn this work, we introduce rental markets in a general equilibrium model with borrowing constraints and infinitely lived agents. We estimate our model using standard Bayesian methods and match US data on recent decades. We highlight a crucial relationship that strongly links interest rates, house prices, and rents. It represents agents’ arbitrage when choosing their degree of participation in the housing market (i.e. their real estate holdings). This framework is particularly well suited for explaining how policy-induced changes in households’ preferences have driven house prices up while pushing rent-price ratios down in the aftermath of the Covid-19 outbreak. It also allows us to parsimoniously track the unequal impact of these changes on agents’ decisions and welfare, which crucially depends on whether they are owners or renters.
The ingroup love and outgroup hate of Christian Nationalism: experimental evidence about the implementation of the rule of law
Authors: Broeren Zachary D. , Djupe Paul A. 
Published: December 2023

Abstract
A long line of research has established that Americans who subscribe to Christian nationalism have a preference for those inside their group and animosity toward those outside their group. These beliefs may impede the equal application of the rule of law, a link that has been suggested but not formally tested. Utilizing experimental data from a survey conducted in fall 2021, we assess the equal application of the rule of law for in and outgroup members conditional on Christian nationalism and belief in Christian persecution. We suggest that ingroup love may move distinctly from outgroup hate. Our results suggest that Christian nationalists have a preference for the ingroup, but do not automatically denigrate outgroups. However, belief in Christian persecution drives animosity toward outgroups, while not elevating the ingroup. Christian nationalist outgroup hatred must be triggered by threat, which has been the project of movement and party elites.
Associations between epigenome-wide DNA methylation and height-related traits among Sub-Saharan Africans: the RODAM study

Published: December 2023

AbstractHuman height and related traits are highly complex, and extensively research has shown that these traits are determined by both genetic and environmental factors. Such factors may partially affect these traits through epigenetic programing. Epigenetic programing is dynamic and plays an important role in controlling gene expression and cell differentiation during (early) development. DNA methylation (DNAm) is the most commonly studied epigenetic feature. In this study we conducted an epigenome-wide DNAm association analysis on height-related traits in a Sub-Saharan African population, in order to detect DNAm biomarkers across four height-related traits. DNAm profiles were acquired in whole blood samples of 704 Ghanaians, sourced from the Research on Obesity and Diabetes among African Migrants study, using the Illumina Infinium HumanMethylation450 BeadChip. Linear models were fitted to detect differentially methylated positions (DMPs) and regions (DMRs) associated with height, leg-to-height ratio (LHR), leg length, and sitting height. No epigenome-wide significant DMPs were recorded. However we did observe among our top DMPs five informative probes associated with the height-related traits: cg26905768 (leg length), cg13268132 (leg length), cg19776793 (height), cg23072383 (LHR), and cg24625894 (sitting height). All five DMPs are annotated to genes whose functions were linked to bone cell regulation and development. DMR analysis identified overlapping DMRs within the gene body of HLA-DPB1 gene, and the HOXA gene cluster. In this first epigenome-wide association studies of these traits, our findings suggest DNAm associations with height-related heights, and might influence development and maintenance of these traits. Further studies are needed to replicate our findings, and to elucidate the molecular mechanism underlying human height-related traits.

Published: December 2023

AbstractThis letter, written by two early career researchers, highlights their urgent concerns regarding the future of scientific ocean drilling (SciOD) research following the retirement of the JOIDES Resolution (JR) at the end of the 2024 fiscal year. In the letter, addressed to the director of NSF‐OCE and to key leaders in determining U.S. scientific priorities, we outline the importance of scientific ocean drilling, both historically and for future scientific advances. We urge the NSF to make immediate, concrete commitments to fund, develop, and construct a new riserless drilling vessel dedicated to SciOD. We also highlight the importance of supporting existing and future SciOD researchers and infrastructure, including the urgent need to create programs designed to support early career researchers in our field. The letter has been signed by nearly three hundred scientists, more than two hundred of which are U.S.‐based researchers and more than half of which are early career researchers.

AbstractOn 15 September 2021, Chandra carried out a 40‐hr (∼4 jovian rotations) observation as part of its longest planetary campaign to study the drivers of jovian X‐ray aurora that may be linked to ultra‐low frequency (ULF) wave activity. During this time, Juno's orbit had taken the spacecraft into Jupiter's dusk magnetosphere. Here is believed to be the most probable location of ULF waves propagating along jovian magnetic field lines that drive the X‐ray auroral emissions. This is the first time that this region has been observed by an orbiter since Galileo >20 years ago, and never before has there been contemporaneous in situ and X‐ray observations. A 1D solar wind propagation model identifies a compression event near the midpoint of the 40‐hr observation window. The influence of a compression is confirmed when comparing the measured magnetic field in the dusk lobes of the magnetotail from Juno MAG data against a baseline lobe field model. Data from the Juno Waves instrument also show activation of broadband kilometric (bKOM) emissions during the arrival of the shock, a feature that has previously been observed during compression events. Therefore this is the first time we can fully analyze the morphological variability during the evolution of a shock. Wavelet transforms and Rayleigh testing are used to search for statistically significant quasi‐periodic pulsations (QPPs) of the X‐ray emissions in the data set, and find significant QPPs with periods of 25–26 min for the northern auroral X‐rays.
The Evolution of Solar Tide‐Like Signatures in the Ionospheric Total Electron Content During Major Sudden Stratospheric Warming Events

Published: December 2023

AbstractBy using total electron content (TEC) from the global ionospheric maps, the solar tide‐like signatures in the ionosphere are explored. We further study how the main components evolve during the 2009 and 2018 major stratospheric sudden warming events (SSWs). The method of a least‐square fit is applied for extracting the solar tide‐like components. The three predominant components are SW2, D0, and SW1, amplitude of which increase in the equatorial ionization anomaly region after the onset of both SSW events, especially in the northern hemisphere. During the SSW events, the solar tide‐like components vary significantly with latitude and their evolutions show hemispherical asymmetries. Each same component presents similar evolutionary trend during both events. The characteristics of ionospheric tide‐like signatures and related mechanisms are discussed. The SW2 tide‐like responses in TEC closely follow the changes in the tidal wind fields in the lower thermosphere, which provide evidences of the atmosphere‐ionosphere coupling during SSW events. In addition, the latitudinal asymmetric distributing of stratospheric ozone and ionospheric TEC background during the SSW may be influence factors for the hemispherical asymmetries in tide‐like signatures responses in TEC.
Defining the Multiscalar Index Timescale—Soil Water Depth Continuum for the Southwestern United States
Authors: McKellar Trevor T. , Crimmins Michael A. , Schaap Marcel G. , Rasmussen Craig 
Published: December 2023

AbstractThe lack of long‐term reliable in‐situ soil moisture data sets creates unique drought monitoring challenges for the semi‐arid Southwestern United States (“Southwest”). Land managers use multiscalar meteorological drought indices, like the Standardized Precipitation Index (SPI) and Standardized Precipitation‐Evapotranspiration Index (SPEI), as proxies for soil water availability; however, objectively identifying the index and timescale that best represents soil water availability in semi‐arid environments remains a significant gap for applying available climate information to land management action. Here, we couple site‐specific soil modeling with high resolution, spatially continuous meteorological data sets to define the relationship between index timescale length and soil water availability of different depths. By creating new matric potential indices (MPI) from 0 to 200 cm, we correlate MPI time series with the SPI and SPEI at different timescale lengths to identify the best index‐timescale combination for each depth. Results indicate the general relationship between highest correlating index‐timescale and MPI‐depth operates roughly on a 1‐month:5 cm step progression at shallow depths (<80 cm). Analysis by soil texture class shows that soils with higher clay content produce shallower sloped relationships (>1‐month:5 cm) than sandy soils (<1‐month:5 cm). Overall, the SPI produced higher correlations and less error with the MPI compared to the SPEI across all texture classes and depths. Thus, the SPI is a good indicator of soil water availability at shallow depths (<80 cm) and should be considered for soil drought monitoring on Southwestern drylands. However, land managers should consult local soils information, if available, given the impacts of texture class on timescale‐depth relationships.
Methane Gas Ebullition Dynamics From Different Subtropical Wetland Vegetation Communities in Big Cypress National Preserve, Florida Are Revealed Using a Multi‐Method, Multi‐Scale Approach
Authors: Sirianni Matthew J. , Comas Xavier , Anderson Frank E. 
Published: December 2023

AbstractMethane (CH4) emissions from peat soils are highly variable in space and time and are influenced by changes in biogeochemical controls and other environmental factors. Areas or times with disproportionally high CH4 emissions in wetlands may develop where conditions are especially conducive for microbial processes like methanogenesis. Currently, eddy covariance methods are employed to quantify CH4 exchanges over several extensive subtropical forested wetland communities in the Big Cypress National Preserve, Florida. In this work, we investigate the importance of multi‐scale measurements to characterize CH4 ebullition dynamics from subtropical wetlands. Our approach uses a combination of gas traps, time‐lapse photography, and capacitance probes to characterize ebullition dynamics from two different wetland vegetation communities for comparison to eddy covariance CH4 measurements at the site. Ground‐penetrating radar surveys and soil sampling are used to assess differences in subsurface properties between sites that influence ebullition. Our results show that the mean measurement bias between fluxes measured in this study and the eddy covariance measurements over the same period was 10–14 times larger during the wet season when ebullition rates were greatest, than the dry season, when ebullition rates were smallest. This suggests that eddy covariance measurements may underestimate the CH4 contribution of ebullition across heterogeneous wetland vegetation communities and that the comparability of CH4 fluxes from methods varying in spatio‐temporal scale changes in response to subtropical Florida seasonality. Our work suggests that these methods can be used to complement eddy covariance measurements and improve the characterization of ebullition dynamics in subtropical wetlands.
A Multivariate Frequency Analysis Framework to Estimate the Return Period of Hurricane Events Using Event‐Based Copula

Published: December 2023

AbstractThis study proposed a framework to evaluate multivariate return periods of hurricanes using event‐based frequency analysis techniques. The applicability of the proposed framework was demonstrated using point‐based and spatial analyses on a recent catastrophic event, Hurricane Ian. Univariate, bivariate, and trivariate frequency analyses were performed by applying generalized extreme value distribution and copula on annual maximum series of flood volume, peak discharge, total rainfall depth, maximum wind speed, wave height and storm surge. As a result of point‐based analyses, return periods of Hurricane Ian was investigated by using our framework; univariate return periods were estimated from 39.2 to 60.2 years, bivariate from 824.1 to 1,592.6 years, and trivariate from 332.1 to 1,722.9 years for the Daytona‐St. Augustine Basin. In the Florida Bay‐Florida Keys Basin, univariate return periods were calculated from 7.5 to 32.9 years, bivariate from 36.5 to 114.9 years, and trivariate from 25.0 to 214.8 years. Using the spatial analyses, we were able to generate the return period map of Hurricane Ian across Florida. Based on bivariate frequency analyses, 18% of hydrologic unit code 8 (HUC8) basins had an average return period of more than 30 years. Sources of uncertainty, due to the scarcity of analysis data, stationarity assumption and impact of other weather systems such as strong frontal passages, were also discussed. Despite these limitations, our framework and results will be valuable in disaster response and recovery.
