Understanding Russophone Estonian Identity Through Popular Culture: An Analysis of Hip-Hop Hit “für Oksana”
Authors: Cole Michael 
Published: November 2022

AbstractSince emerging in the early 1990s, Estonian hip-hop has developed in line with other cultural and artistic projects in the country, reflecting attempts to foster a homogeneous society, yet ultimately cultivating one where diversity and multiculturalism prevail. As a genre where minority groups are frequently presented as “authentic,” hip-hop and its visual and performative manifestations provide a valuable platform to examine expressions of identity. To this end, several Estonian hip-hop musicians have explored aspects of being “post-Soviet” in contradistinction to official hegemonic discourses, which outright reject the Soviet past and emphasize titular ethnicity as a cornerstone of national identity.This article uses Critical Discourse Analysis (CDA) and Multi-Modal Discourse Analysis (MMDA) to examine the lyrics and accompanying video of popular hip-hop song “für Oksana” by “Nublu featuring Gameboy Tetris.” Doing so highlights how the song’s basic narrative acts as a metaphor for experiences of integration processes between ethnic Estonians and Russophones since Estonian independence. I argue that through a combination of linguistic and cultural codeswitching, “für Oksana” constitutes an expression, performance, and negotiation of Russophone Estonian identity from both insider and outsider perspectives, emphasizing the need to understand Russophone Estonians as more than simply “Russians who live in Estonia.”

Published: November 2022

AbstractFor a graph G, let
$f(G)$
denote the maximum number of edges in a bipartite subgraph of G. Given a positive integer m and a fixed graph H, let
$f(m,H)$
denote the minimum possible cardinality of
$f(G)$
, as G ranges over all graphs on m edges that contain no copy of H. We prove bounds on
$f(m,H)$
for some bipartite graphs H and give a bound for a conjecture of Alon et al. [‘MaxCut in H-free graphs’, Combin. Probab. Comput.14 (2005), 629–647] concerning
$f(m,K_{4,s})$

Income inequality and opinion expression gap in the American public: an analysis of policy priorities
Authors: Yildirim Tevfik Murat , Bulut Alper T. 
Published: November 2022

AbstractPast scholarship has documented that the poor are more likely to withhold their policy preferences in public opinion surveys, suggesting income gaps in political engagement. Despite the wealth of scholarly interest in opinion formation, however, previous studies focused almost exclusively on opinion gaps in preferences, leaving income-related gaps in policy prioritisation virtually unexamined. Drawing on 596 public opinion surveys conducted with nearly 700,000 Americans over 55 years, we make a comprehensive attempt to examine income-level differences in “don’t know” responses to the most important problem (MIP) question. Our results show that the less affluent are more likely to say “don’t know” when asked about the MIP facing their country, even after controlling for various factors including educational attainment and political attention. Importantly, we also show that income-related differences in opinionation cross cut other socio-economic differences in policy prioritisation. These results have important implications for the study of public opinion.
Official discretion, errors, and oversights: legal bureaucracy and the question of justice in twentieth-century India
Authors: Wani Javed Iqbal 
Published: November 2022

AbstractLate colonial juridical practice in India was prone to bureaucratic errors and shared with the police a fundamental disinterest in the liberty of ordinary people. This article tells the politically marginal but highly revealing story of how a series of errors during the arrest and subsequent detention of an elderly man called Peter Budge—an innocent bystander in a situation of heightened communal tensions—led to a momentary scandal in the United Provinces administration in the year 1947–48. Peter's case disappeared between the cracks of bad record-keeping, leading to his lengthy and unlawful detention. It raises important questions about the complementary relation between law and violence, and the fictitious nature of public-order laws. In contrast to the scholarship that has discussed the spectacular violence of the state, this article looks at the ‘other’ acts of violence of the state and argues that the everyday reality of public-order enforcement is key to understanding the nature and operations of the late colonial and post-colonial state.

Published: November 2022

AbstractObjective:The COVID-19 pandemic changed early care and education (ECE) mealtimes. Feeding practices that support children’s emerging autonomy may support children’s healthy eating, but it is unknown whether and how COVID-19 changed feeding practices. This paper describes caregiver feeding practices in ECE centres in Florida during COVID-19.Design:A mixed-methods design was used to understand mealtime feeding practices. Survey and interview questions were developed based on the Trust Model. More than 7000 surveys were sent to ECE centres. Analysis included descriptive statistics for survey data and thematic analysis for interview data.Setting:This statewide study included teachers in all licensed and license-exempt ECE centres.Participants:Four hundred and thirty-one teachers completed a survey, and twenty-nine participated in follow-up interviews.Results:Surveys showed most teachers engaged in autonomy-supportive behaviours, such as letting children eat until they were finished (90 %). The most common controlling behaviour was praising children for cleaning their plates (70 %). The most common responses about changes to mealtimes were keeping physical distance and serving healthy food. Interview themes were Autonomy Support, Controlling Feeding Practices, Interactions are the Same, Interactions are Different, Physical Distancing and Healthy Eating.Conclusions:Mealtimes are a central part of the day for young children and teachers in ECE environments. COVID-19 continues to influence ECE routines as behaviour change remains the primary method of reducing the risk of COVID-19 in the absence of a vaccine for young children. Understanding teachers’ practices and perspectives is important for reducing the risk of COVID-19 and supporting children’s autonomy and healthy eating.
Advancing rights and inclusion of persons with disabilities in humanitarian action: a donor perspective
Authors: Mojtahedi Mina C. , Mikkola Riikka , Saxén Niklas 
Published: November 2022

AbstractDespite increasing awareness and high-level commitments on disability inclusion by humanitarian donors and actors, persons with disabilities continue to be ignored from humanitarian assistance. Rights and inclusion of persons with disabilities are a foreign policy priority for the Ministry for Foreign Affairs of Finland, including in humanitarian assistance. The primary means for donors, such as Finland, to promote disability-inclusive humanitarian action are funding and advocacy. Trade-offs between flexible and earmarked funding for disability inclusion are challenging when reporting on results is inadequate. This article shares examples on how the Ministry promotes inclusion of persons with disabilities in humanitarian action and explores challenges that need to be resolved by stakeholders.
Investigating the Role of Magnetosheath High‐Speed Jets in Triggering Dayside Ground Magnetic Ultra‐Low Frequency Waves
Authors: Wang Boyi , Nishimura Yukitoshi , Hietala Heli , Angelopoulos Vassilis 
Published: November 2022

AbstractUltra‐low frequency (ULF) waves significantly contribute to transferring energy and transporting particles in the coupled magnetosphere‐ionosphere system. Recent studies suggested magnetosheath high‐speed jets (HSJs) can drive magnetospheric ULF waves, but whether they can be an important source of dayside ground magnetic ULF oscillations has not been examined thoroughly. Utilizing 5 years of observations by the Time History of Events and Macroscale Interactions During Substorms satellites and ground‐based magnetometers, we found that 37% of all the observed magnetosheath HSJs can trigger ground magnetic field oscillations and were thus determined as geoeffective HSJs. The occurrence rate has positive relationship with increasing flow speed and dynamic pressure of magnetosheath HSJs. We propose that magnetosheath HSJs can be a source of dayside ground magnetic ULF oscillations. We also identified the different behaviors of isolated and recurrent magnetosheath HSJs in generating ground magnetic ULF oscillations. The recurrence time of recurrent magnetosheath HSJs likely determines the frequencies of the ULF oscillations.

AbstractThe mild degassing and effusion that characterizes open‐vent volcanoes can be interrupted by episodes of sustained explosive activity known as paroxysms. Here, we present observations from a seismic array deployment during the 2021 eruption of Mt. Etna, Italy. During the observation period, degassing dominated surface activity at the central and northeast summit craters; lava flows, Strombolian explosions, and fire fountaining, accompanied by ash plumes, characterized eruption in the southeast sector of Mt. Etna. Seismic array locations showed changes associated with shifts in the style and location of activity across multiple craters at Mt. Etna. We observed changes in array locations between the north‐northeast and southeast directions that consistently anticipated the onset of paroxysmal activity in the southeast sector. Our results demonstrate the potential of seismic arrays to resolve vent‐specific activity and shed light on precursory patterns leading up to paroxysmal activity.
Model Projections of Increased Severity of Heat Waves in Eastern Europe
Authors: Turnau Roger , Robinson Walter A. , Lackmann Gary M. , Michaelis Allison C. 
Published: November 2022

AbstractExtreme heat is investigated in a series of high‐resolution time‐slice global simulations comparing the current and late‐21st century climates. An increase in climate‐relative extreme heat is found in the region surrounding the Black Sea. Similarities between the synoptic‐scale flows in current and future heat events combined with a decrease in future summer precipitation suggests that the increased future severity stems from strengthened land‐atmosphere feedbacks driven primarily by the changes in precipitation. The resulting intensification of heat events beyond the mean warming driven by climate change could generate significant future heat hazards in vulnerable regions. Given the continental cool bias in the present‐day simulations, the resulting estimates of future extreme heat are likely to be conservative.

AbstractCover crops have critical significance for agroecosystem sustainability and have long been promoted in the U.S. Midwest. Knowledge of cover cropping variations and impacts of government policies remains very limited. We developed an accurate and cost‐effective approach utilizing satellite fusion data, environmental variables, and machine learning to quantify cover cropping in corn and soybean fields from 2000 to 2021 in the U.S. Midwest. We found that cover crop adoption in most counties was stagnant from 2000 to 2011, but has significantly increased from 2011 to 2021. The adoption of 2021 is four times that of 2011, which was highly correlated to the funding for conservation programs. However, the percentage of cover crop adoption in the U.S. Midwest is still low (7.2%). Our work fills a critical gap in quantifying long‐term field‐level cover crop adoption at large regions and highlights the potential importance of incentive programs to promote sustainable agricultural practices.
Influence of African Easterly Wave Suppression on Atlantic Tropical Cyclone Activity in a Convection‐Permitting Model
Authors: Danso Derrick K. , Patricola Christina M. , Bercos‐Hickey Emily 
Published: November 2022

AbstractAfrican easterly waves (AEWs) are strongly linked to Atlantic tropical cyclones (TCs) on the synoptic timescale by serving as seedling disturbances for TC genesis. However, it is unclear whether climatological TC frequency is limited by AEWs. We investigated the impact of suppressing AEWs using a 3‐member ensemble of convection‐permitting regional model simulations, in which AEWs were either retained or removed through the lateral boundary conditions. Suppressing AEWs did not substantially change seasonal TC number, but did influence TC intensity, genesis time and location. Suppressing AEWs produced stronger TCs, shifted peak TC genesis from September to August, and reduced (increased) TC genesis in the eastern Atlantic (Gulf of Mexico). Without AEWs, TCs generated under more favorable large‐scale atmospheric conditions. These results indicate that AEWs may not be reliable predictors of basin‐wide seasonal TC frequency. However, simulations provide evidence that AEWs could influence the large‐scale environment that is important for TCs.

AbstractThe dispersal of dissolved iron (DFe) from hydrothermal vents is poorly constrained. Combining field observations and a modeling hierarchy, we find the dispersal of DFe from the Trans‐Atlantic‐Geotraverse vent site occurs predominantly in the colloidal phase and is controlled by multiple physical processes. Enhanced mixing near the seafloor and transport through fracture zones at fine‐scales interacts with the wider ocean circulation to drive predominant westward DFe dispersal away from the Mid‐Atlantic ridge at the 100 km scale. In contrast, diapycnal mixing predominantly drives northward DFe transport within the ridge axial valley. The observed DFe dispersal is not reproduced by the coarse resolution ocean models typically used to assess ocean iron cycling due to their omission of local topography and mixing. Unless biogeochemical models account for fine‐scale physics and colloidal Fe, they will inaccurately represent DFe dispersal from axial valley ridge systems, which make up half of the global ocean ridge crest.

AbstractWe investigate Mars‐ward planetary ions (O+ and O2+) in the Martian magnetotail that potentially reduce the amount of escaping ions. The global properties of Mars‐ward flows in the Martian magnetotail are characterized, based on over 13‐years of ion data (May 2007–December 2020) collected by the Analyzer of Space Plasma and Energetic Atoms instrument on Mars Express. We find that Mars‐ward flows are frequently observed in the vicinity of the crustal fields, implying that crustal fields may play a key role in producing such flows. The occurrence rate and sunward flux are found higher during solar maximum than solar minimum. However, the occurrence rate and flux of Mars‐ward flows are relatively low. This is different from the case at Venus, where the planetward flows can significantly decrease the total escape rates of ions.
Field and Numerical Investigations of Wave Effects on Groundwater Flow and Salt Transport in a Sandy Beach

Published: November 2022

AbstractCoastal dynamic forces, such as waves and tides, altogether drive groundwater circulation and salt transport in the intertidal zone. However, few numerical studies have ever considered the combined effects of waves and tides. In this study, the fluctuations of wave height are integrated with tidal level together using an iterative least squares fitting method, in which the wave height can be acquired from measured sea level in the surf zone, and this fitted wave height is further verified by wind speed. Groundwater flow and salt transport were then simulated using the MARUN code to evaluate the impacts after considering wave effect. The simulated equivalent freshwater head and salinity of the model with wave effect presented less difference with the measured data compared with the simulated results of the model without wave effect. After incorporating the wave effect in a model, submarine groundwater discharge (SGD) was increased, among which recirculated SGD grew more rapidly than the fresh, leading to the proportion of the fresh SGD accounting for a small proportion (1.1%). The water influx and efflux rates increased greatly especially during the period of high wave height. Most of the influx occurred in the intertidal zone, while a considerable amount of efflux occurred in the subtidal zone. The iterative algorithm to separate the wave height from the mixed field data can be employed to identify and quantify the respective effects of tides and the combined effects of waves and tides on the density‐dependent beach groundwater flow.

AbstractWater transit time is now a standard measure in catchment hydrological and ecohydrological research. The last comprehensive review of transit time modeling approaches was published 15+ years ago. But since then the field has largely expanded with new data, theory and applications. Here, we review these new developments with focus on water‐age‐balance approaches and data‐based approaches. We discuss and compare methods including StorAge‐Selection functions, well/partially mixed compartments, water age tracking through spatially distributed models, direct transit time estimates from controlled experiments, young water fractions, and ensemble hydrograph separation. We unify some of the heterogeneity in the literature that has crept in with these many new approaches, in an attempt to clarify the key differences and similarities among them. Finally, we point to open questions in transit time research, including what we still need from theory, models, field work, and community practice.

Published: November 2022

Abstract
Background
Naturally occurring germline gene deletions (KO) represent a unique setting to interrogate gene functions. Complete deletions and differential expression of the human glycosyltransferase UGT2B17 and UGT2B28 genes are linked to prostate cancer (PCa) risk and progression, leukaemia, autoimmune and other diseases.

Methods
The systemic metabolic consequences of UGT deficiencies were examined using untargeted and targeted mass spectrometry-based metabolomics profiling of carefully matched, treatment-naive PCa cases.

Results
Each UGT KO differentially affected over 5% of the 1545 measured metabolites, with divergent metabolic perturbations influencing the same pathways. Several of the perturbed metabolites are known to promote PCa growth, invasion and metastasis, including steroids, ceramides and kynurenine. In UGT2B17 KO, reduced levels of inactive steroid-glucuronides were compensated by sulfated derivatives that constitute circulating steroid reservoirs. UGT2B28 KO presented remarkably lower levels of oxylipins paralleled by reduced inflammatory mediators, but higher ceramides unveiled as substrates of the enzyme in PCa cells.

Conclusion
The distinctive and broad metabolic rewiring caused by UGT KO reinforces the need to examine their unique and divergent functions in PCa biology.

Published: November 2022

Abstract
Background
Intratumoral heterogeneity (ITH) is a major problem in gastric cancer (GC). We tested Ki67 and tumor regression for ITH after neoadjuvant/perioperative chemotherapy.

Methods
429 paraffin blocks were obtained from 106 neoadjuvantly/perioperatively treated GCs (one to five blocks per case). Serial sections were stained with Masson’s trichrome, antibodies directed against cytokeratin and Ki67, and finally digitalized. Tumor regression and three different Ki67 proliferation indices (PI), i.e., maximum PI (KiH), minimum PI (KiL), and the difference between KiH/KiL (KiD) were obtained per block. Statistics were performed in a block-wise (all blocks irrespective of their case-origin) and case-wise manner.

Results
Ki67 and tumor regression showed extensive ITH in our series (maximum ITH within a case: 31% to 85% for KiH; 4.5% to 95.6% for tumor regression). In addition, Ki67 was significantly associated with tumor regression (p < 0.001). Responders (<10% residual tumor, p = 0.016) exhibited prolonged survival. However, there was no significant survival benefit after cut-off values were increased ≥20% residual tumor mass. Ki67 remained without prognostic value.

Conclusions
Digital image analysis in tumor regression evaluation might help overcome inter- and intraobserver variability and validate classification systems. Ki67 may serve as a sensitivity predictor for chemotherapy and an indicator of ITH.
