The radial action from probe amplitudes to all orders
Authors: Kol Uri , O’Connell Donal , Telem Ofri
Published: March 2022

Abstract

We extract the relativistic classical radial action from scattering amplitudes, to all orders in perturbation theory, in the probe limit. Our sources include point charges and monopoles, as well as the Schwarzschild and pure-NUT gravitational backgrounds. A characteristic relativistic effect, that scattering trajectories may wind around these sources any number of times, can be recovered when all-order amplitudes are available. We show that the amplitude for scattering a probe off a pure NUT is given by the solution of a transcendental equation involving continued fractions, and explain how to solve this equation to any desired loop order.
Simulation-based design of flank face modification for the milling of Ti-6Al-4V and Inconel 718
Authors: Denkena Berend , Bergmann Benjamin , Worpenberg Sebastian
Published: March 2022

The milling of titanium and nickel-based alloys leads to high tool wear due to the high thermomechanical load on the tool. By modifying the flank face on end mills, it is possible to limit the increase in the width of flank wear land, thus increasing tool life, component quality and increasing the allowable productivity of the tools. The flank face modification is characterized by the width and depth of the undercut and the rounding in the undercut of the modification. Through a simulation-based approach, a method is created to design the flank face modification in a load-optimized way and thus to use the full potential in the respective application cases.
Permutability of matrices over bipotent semirings
Authors: Aird Thomas , Kambites Mark
Published: March 2022

We study permutability properties of matrix semigroups over commutative bipotent semirings (of which the best-known example is the tropical semiring). We prove that every such semigroup is weakly permutable (a result previous stated in the literature, but with an erroneous proof) and then proceed to study in depth the question of when they are strongly permutable (which turns out to depend heavily on the semiring). Along the way we classify monogenic bipotent semirings and describe all isomorphisms between truncated tropical semirings.

Main conclusion

By combining hyperspectral signatures of peanut and soybean, we predicted Vcmax and Jmax with 70 and 50% accuracy. The PLS was the model that better predicted these photosynthetic parameters.

One proposed key strategy for increasing potential crop stability and yield centers on exploitation of genotypic variability in photosynthetic capacity through precise high-throughput phenotyping techniques. Photosynthetic parameters, such as the maximum rate of Rubisco catalyzed carboxylation (Vc,max) and maximum electron transport rate supporting RuBP regeneration (Jmax), have been identified as key targets for improvement. The primary techniques for measuring these physiological parameters are very time-consuming. However, these parameters could be estimated using rapid and non-destructive leaf spectroscopy techniques. This study compared four different advanced regression models (PLS, BR, ARDR, and LASSO) to estimate Vc,max and Jmax based on leaf reflectance spectra measured with an ASD FieldSpec4. Two leguminous species were tested under different controlled environmental conditions: (1) peanut under different water regimes at normal atmospheric conditions and (2) soybean under high [CO2] and high night temperature. Model sensitivities were assessed for each crop and treatment separately and in combination to identify strengths and weaknesses of each modeling approach. Regardless of regression model, robust predictions were achieved for Vc,max (R2 = 0.70) and Jmax (R2 = 0.50). Field spectroscopy shows promising results for estimating spatial and temporal variations in photosynthetic capacity based on leaf and canopy spectral properties.
An extended Boussinesq theory for interfacial fluid mechanics
Authors: Forbes Lawrence K. , Turner Ross J. , Walters Stephen J.
Published: March 2022

Boussinesq theory can model quite accurately viscous flows that involve multiple fluids with interfaces between them, so long as there is not much difference between the densities of the various fluids. However, the Boussinesq approximation is generally poor when the density ratio between the fluids is large. Here, we propose an Extended Boussinesq approximate equation, that allows for large density ratios, while still remaining straightforward to implement. Examples are given for planar Rayleigh–Taylor instability, where the Boussinesq and the novel Extended Boussinesq models are compared with the predictions of an SPH fluid dynamics code, to confirm this approach.

Purpose

Highly localized impedance (LI) measurements during atrial fibrillation (AF) ablation have emerged as a viable real-time indicator of tissue characteristics and the consequent durability of the lesions created. We investigated the impact of catheter-tissue contact force (CF) on LI behavior during pulmonary vein isolation (PVI).

Methods

Forty-five consecutive patients of the CHARISMA registry undergoing de novo AF radiofrequency (RF) catheter ablation with a novel open-irrigated-tip catheter endowed with CF and LI measurement capabilities (Stablepoint™ catheter, Boston Scientific) were included.

Results

A total of 2895 point-by-point RF applications were analyzed (RF delivery time (DT) = 8.7±4s, CF = 13 ±±8 g, LI drop = 23 ±±7 Ω). All PVs were successfully isolated in an overall procedure time of 118 ±±34 min (fluoroscopy time = 13 ±±8 min). The magnitude of LI drop weakly correlated with CF (r = 0.13, 95% confidence interval (CI): 0.09 to 0.16, p < 0.0001), whereas both CF and LI drop inversely correlated with DT (r = −0.26, 95%CI: −0.29 to −0.22, p < 0.0001 for CF; r = −0.36, 95%CI: −0.39 to −0.33, p < 0.0001 for LI). For each 10 g of CF, LI drop markedly increased from 22.4 ± 7 Ω to 24.0 ± 8 Ω at 5 to 25 g CF intervals (5–14 g of CF vs 15–24 g of CF, p < 0.0001), whereas it showed smooth transition over 25 g (24.8 ± 7Ω at ≥ 25 g CF intervals, p = 0.0606 vs 15–24 g of CF). No major complications occurred during the procedures or within 30 days.

Conclusions

CF significantly affects LI drop and probable consequent lesion formation during RF PVI. The benefit of higher contact (> 25 g) between the catheter and the tissue appears to have less impact on LI drop.

Introduction

Efforts to recruit and retain diverse Maternal and Child Health (MCH) professionals are of paramount public health significance. Culturally congruent mentorship strategies are key to supporting a successful transition from undergraduate to graduate studies.

Methods

This mixed-method study evaluated a culturally congruent mentorship training used by one of the MCH Pipeline Training programs and described mentorship practices and lessons learned from the six MCH Pipeline programs. A retrospective pre-test post-test survey assessed mentorship competency skills following a mentoring workshop. All MCH Pipeline program leaders completed a questionnaire to elicit responses about mentoring training practices, mentor evaluation strategies, and lessons learned.

Results

Maternal and Child Health Pipeline Training Programs supported 1890 undergraduate scholars at universities and institutions nationally. Scholars at six MCH Pipeline Programs participated in MCH education and mentored experiential leadership opportunities in clinical practice, research, and public health education. Qualitative program-level mentor survey themes indicated the importance of creating a reflective space and building mentorship teams. Mean mentor self-assessed improvement in mentor competencies was 14.4 points, 95% CI [10.5, 18.3], p < .001 following completion of a mentoring training workshop implemented by one of the MCH Pipeline programs.

Discussion

The Health Resources and Services Administration’s Maternal and Child Health Bureau recognized the need to support the development of the next generation of diverse MCH leaders. Pipeline programs that included mentoring workshops and building culturally congruent mentorship teams are two strategies to increase and retain diverse scholars in graduate school and leaders in the public health workforce.
Social embeddedness of pig value chains in Myanmar and its implications for food and nutrition security
Authors: Ebata Ayako
Published: March 2022

Agricultural intermediaries – traders and middlemen/women – play a critical role for food security in low- and middle-income countries (LMICs). Yet, their role in improving or undermining food safety, an indicator for food quality, is not well understood. As middle-class citizens increasingly demand high-quality perishable and nutritious produce, food safety has become an important issue in LMICs. The existing literature offers limited insights as to whether and, if so, how intermediaries manage information regarding food safety in LMICs. This article fills this gap based on an in-depth qualitative study on pig value chains in Myanmar. We document that intermediaries helped reduce transaction costs of trade by linking farmers to buyers based on an intricate socio-economic relationship. While we find no evidence of intermediaries actively concealing facts about invisible (i.e. microbiological or chemical) nature of pig products, they facilitated selling sick animals. On the other hand, intermediaries withheld information about potential buyers and sellers in order to maintain their role along the value chains. In order to improve food safety in LMICs, policies need to reduce transaction costs of trade as well as access to public health expertise.
Women, Painful Sex, and Mindfulness
Authors: Pernilla Maathz , Lance McCracken , Johanna Ekdahl , Thomas Parling , JoAnne Dahl
Published: March 2022

Objectives

Mindfulness-based approaches to treatment of sexual dysfunction associated with vulvar pain appear promising, but little is known about the specific processes of mindfulness in sexual interactions or if mindfulness may be of particular benefit to women who experience pain associated with sexual activity. This study aimed to examine the associations between sexual mindfulness and sexual function and distress among women who currently experience pain with sexual activity as compared to women who do not.

Methods

Women over the age of 18 were invited to complete an online survey, including measures of mindfulness in sexual activity, pain associated with sexual activity, sexual function, and sexual distress. Of the participants, 134 (42.1%) were experiencing pain and 184 (57.9%) were pain free.

Results

Higher levels of mindfulness during sexual activity were associated with greater sexual functioning and less sexual distress both among women with and without pain. However, the association between Observing skills and sexual functioning among women with pain was weaker if the capacity for nonreactivity was low. Sexual mindfulness contributed significantly to the explanation of sexual function and distress in both groups. Of the mindfulness facets, Acting with awareness consistently contributed, beyond the other facets, to the explanation of sexual outcomes.

Conclusions

The capacity to stay mindful in sexual interactions appears to be important to sexual functioning both among women who experience pain with sexual activity and among women who do not. These findings encourage further examination of the role of mindfulness and its facets in sexual outcomes.
Re-thinking of T-tube use in whole liver transplantation: an analysis on the risk of delayed graft function
Authors: Pravisani Riccardo , Isola Miriam , Lorenzin Dario , Cherchi Vittorio , Boscolo Erica , Mocchegiani Federico , Terrosu Giovanni , Baccarani Umberto
Published: March 2022

The liver–gut axis has been identified as crucial mediator of liver regeneration. Thus, the use of a T-tube in liver transplantation (LT), which interrupts the enterohepatic bile circulation, may potentially have a detrimental effect on the early allograft functional recovery. We retrospectively analyzed a cohort of 261 patients transplanted with a whole liver graft, with a duct-to-duct biliary anastomosis, who did not develop any surgical complication within postoperative day 14. Early allograft dysfunction (EAD) was defined according to the criteria of Olthoff et al. (EAD-O), and graded according to the Model for Early Allograft Function (MEAF) score. EAD-O developed in 24.7% of recipients and the median MEAF score was 4.0 [interquartile range 2.9–5.5]. Both MEAF and EAD predicted 90-day post-LT mortality. A T-tube was used in 49.4% of cases (n = 129). After a propensity score matching for donor age, cold and warm ischemia time, donor risk index, balance of risk score, Child–Pugh class C, and MELD score, the T-tube group showed a significantly higher prevalence of EAD-O and value of MEAF than the no-T-tube group (EAD-O: 29 [34.1%] vs 16 [19.0%], p = 0.027; MEAF 4.5 [3.5–5.7] vs 3.7 [2.9–5.0], p = 0.014). In conclusion, T-tube use in LT may be a risk factor for EAD and higher MEAF, irrespective of graft quality and severity of pre-LT liver disease.
Some new semi-exponential operators
Authors: Abel Ulrich , Gupta Vijay , Sisodia Meer
Published: March 2022

In the theory of approximation, linear operators play an important role. The exponential-type operators were introduced four decades ago, since then no new exponential-type operator was introduced by researchers, although several generalizations of existing exponential-type operators were proposed and studied. Very recently, the concept of semi-exponential operators was introduced and few semi-exponential operators were captured from the exponential-type operators. It is more difficult to obtain semi-exponential operators than the corresponding exponential-type operators. In this paper, we extend the studies and define semi-exponential Bernstein, semi-exponential Baskakov operators, semi-exponential Ismail–May operators related to $$2x^{3/2}$$

A Theoretical Framework for Circular Processes and Circular Impacts Through a Comprehensive Review of Indicators
Authors: Garcia-Saravia Ortiz-de-Montellano Cris , van der Meer Yvonne
Published: March 2022

Circular Economy (CE) is gaining traction among academics and stakeholders; however, there is no unified framework on how to assess it. This paper proposes a framework that is composed of two segments. The first segment includes circular processes based on the value retention stages of products and systems on different levels. The second segment comprises circular impacts measuring the goals of the CE concerning environmental performance, economic contribution, and social impact. There are eight clusters of circular processes: redesign, reduce, use and reuse, re-sell, refurbish and remanufacture, recycle, recover and recirculate. The review shows that there is a widely spread confusion and overlap between indicators for circular processes and circular impacts. A clear differentiation of each category can significantly improve the tools and methods through which to assess CE. This work aims to provide such differentiation and the foundation for the development of a systematic and standardised CE assessment framework. This review provides relevant guidance of circularity indicators to be used at the (re)design phase of products, materials and systems, as well as the environmental, social and economic considerations that circular strategies must have.

Recovery from Psychosis: An Integrated Model of Interpersonal and Intrapersonal Factors from the Perspective of Psychologists
Authors: Atapattu Methma Supathmi , Gonzales Hugo M. , Williams Nigel
Published: March 2022

Psychosis is an encumbering cluster of mental illnesses which has a significant impact on the daily life of individuals. Recovery from psychosis is a personalised process due to the unique nature of the lived experiences of these individuals. Although numerous research have been conducted, there exists a research gap in taking into consideration the perspectives of practitioners in treating the illness. This study aimed to identify the perspectives of psychologists on the impact of interpersonal and intrapersonal factors that impact recovery from psychosis. Five participants were interviewed to qualitatively explore this utilising Interpretative Phenomenological Analysis (IPA). Findings suggested that recovery from psychosis can occur on four different dimensions; Behavioural, Insight, Cognitive, and Social Recovery. There are several interpersonal and intrapersonal factors impacting these dimensions collaboratively. An Integrated Recovery Model was generated to summarise these findings which could potentially assist the recovery process of individuals. Limitations of the study and future implications were also addressed.
Sweat Equity: Student Scholarships in Aotearoa New Zealand’s Universities
Authors: Soar Max , Stewart Lucy , Nissen Sylvia , Naepi Sereana , McAllister Tara
Published: March 2022

This paper responds to calls from past and present students to increase the value of postgraduate scholarships in Aotearoa New Zealand. Here we provide context for understanding the scholarship landscape in Aotearoa, including how scholarships are understood in relation to dominant neoliberal framings of higher education and persistent inequities within the sector. We present data which provides insight into the current inequities in Summer, Masters and PhD scholarship values. The average value of PhD scholarships has remained stagnant between 2011 and 2019 resulting in the average being $11,238 less than the Living Wage in 2019. We show that the average length of time full-time PhD students take to complete their doctorates exceeds the three-year tenure of scholarships. We argue the status-quo of low scholarships, supplemented by postgraduate ‘sweat’, excludes people from participating in postgraduate education, preventing them and their communities from realising the public benefits that such an education can produce. We suggest that these inadequacies could be addressed through (1) raising Summer, Masters and PhD scholarships to the living wage; (2) extending tenure of PhD scholarships; and (3) reinstating the postgraduate student allowance.
Covid 19 - some Lessons from Public Administrations for Humanistic Management
Authors: Ruffini Renato , Traquandi Valerio , Ingaggiati Marta , Barbato Giovanni
Published: March 2022

In order to understand how the logic of public management can enrich humanistic management’s practices, the current paper will analyze the managerial practices adopted by public administrations within a situation of emergency, a condition where the specific features of the public management can emerge more clearly. Specifically, it will focus on the ways in which the municipality of Bergamo (one of the hardest-hit cities) have reacted to the Covid-19 pandemic, outlining interesting managerial practices especially from the point of view of Humanistic Management’s theory. Such interest resides also in the fact that although the Humanistic Management’s field of research has dealt with a wide range of topics (including human development, emancipation and progress), so far, however, it has not yet considered public administrations, whose role is by definition oriented towards human development through the creation of public value. The analysis of public management through the lens of Humanistic Management can be useful in various respects. Above all, the difference between public administrations and private enterprises can also lead to a very much different process of value creation, based on collaborative forms of production as well as relational and reflexive forms of management. In accordance with the Humanistic Management framework, also business organizations must generate social wellbeing. From this point of view, the lesson of public administrations can be extremely useful for business organization and management alike.

Fabricating surface oxygen vacancies is considered to be an efficient method to improve the adsorption performance of sorbents. In this work, a bismuth oxychloride/biochar (BiOCl/BC) nanocomposite with abundant oxygen vacancies was successfully prepared by a facile ball milling method. BiOCl/BC nanocomposite was found to have excellent adsorption performance for removing reactive red-120 (RR120) from aqueous solution. The effects of key adsorption parameters, such as RR120 dye concentration, solution pH (2–10), and contact time were studied by batch adsorption test. The adsorption data were well described by the Langmuir and Freundlich isotherms and pseudo-second-order kinetic models. The 50%-BiOCl/BC (50 wt% of BiOCl in composite) exhibited the best adsorptive performance (60%), much better than the pristine BM-BC (20%). The high adsorption capacity of 50%-BiOCl/BC (Langmuir maximum capacity of 116.382 mg g−1) can be attributed to the electrostatic effect, π–π interactions, and hydrogen bond. This work provided a facile method to prepare semiconductor assisted biochar-based adsorbents, which would also contribute to the advance of environmental remediation.

A perspective on biochar for repairing damages in the soil–plant system caused by climate change-driven extreme weather events
Authors: Kumar Abhishek , Bhattacharya Tanushree , Mukherjee Santanu , Sarkar Binoy
Published: March 2022

There has been more than 75% rise in the number of extreme weather events such as drought and flood during 2000–2019 compared to 1980–1999 due to the adverse effects of climate change, causing significant deterioration of the soil and water quality. Simultaneously, the growing human population has been exerting pressure on available water and soil resources due to overuse or unplanned use. While greenhouse gas emissions have intensified, the fertility of agricultural soils has declined globally due to the exposure of soils to frequent flooding, desertification, and salinization (resulting from extreme weather events). The current review aims to give an overview of damages caused to the soil–plant system by extreme weather events and provide a perspective on how biochar can repair the damaged system. Biochar is known to improve soil fertility, increase crop productivity and mitigate greenhouse gas emissions via sustainable recycling of bio-waste. Beneficial properties of biochar such as alkaline pH, high cation exchange capacity, abundant surface functional groups, remarkable surface area, adequate porosity, excellent water holding capacity, and sufficient nutrient retention capacity can help repair the adverse effects of extreme weather events in the soil–plant system. This paper recommends some cautious future approaches that can propel biochar’s use in improving the soil–plant systems and promoting sustainable functioning of extreme weather-affected areas via mitigation of the adverse effects.

Proletarian Lives
Authors: Pérez Marcos E.
Published: March 2022

Based on multi-year ethnographic fieldwork on the Unemployed Workers' Movement in Argentina (also known as the piqueteros), Proletarian Lives provides a case study of how workers affected by job loss protect their traditional forms of life by engaging in progressive grassroots mobilization. Using life-history interviews and participant observation, the book analyzes why some activists develop a strong attachment to the movement despite initial reluctance and frequent ideological differences. Marcos Pérez argues that a key appeal of participation is the opportunity to engage in age and gender-specific practices associated with a respectable blue-collar lifestyle threatened by long-term socioeconomic decline. Through their daily involvement in the movement, older participants reconstruct the routines they associate with a golden past in which factory jobs were plentiful, younger activists develop the kind of habits they were raised to see as valuable, and all members protect communal activities undermined by the expansion of poverty and violence.
Can Courts be Bulwarks of Democracy?
Authors: Staton Jeffrey K. , Reenock Christopher , Holsinger Jordan
Published: March 2022

Liberal concepts of democracy envision courts as key institutions for the promotion and protection of democratic regimes. Yet social science scholarship suggests that courts are fundamentally constrained in ways that undermine their ability to do so. Recognizing these constraints, this book argues that courts can influence regime instability by affecting inter-elite conflict. They do so in three ways: by helping leaders credibly reveal their rationales for policy choices that may appear to violate legal rules; by encouraging leaders to less frequently make decisions that raise concerns about rule violations; and by encouraging the opposition to accept potential rule violations. Courts promote the prudent use of power in each of these approaches. This book evaluates the implications of this argument using a century of global data tracking judicial politics and democratic survival.
Planning Democracy
Authors: Menon Nikhil
Published: March 2022

The Indian planning project was one of the postcolonial world's most ambitious experiments. Planning Democracy explores how India fused Soviet-inspired economic management and Western-style liberal democracy at a time when they were widely considered fundamentally contradictory. After nearly two centuries of colonial rule, planning was meant to be independent India's route to prosperity. In this engaging and innovative account, Nikhil Menon traces how planning built India's knowledge infrastructure and data capacities, while also shaping the nature of its democracy. He analyses the challenges inherent in harmonizing technocratic methods with democratic mandates and shows how planning was the language through which the government's aspirations for democratic state-building were expressed. Situating India within international debates about economic policy and Cold War ideology, Menon reveals how India walked a tightrope between capitalism and communism which heightened the drama of its development on the global stage.
Explorations in Ancient and Modern Philosophy
Authors: Burnyeat Myles , Atack Carol , Schofield Malcolm , Sedley David
Published: March 2022

Myles Burnyeat (1939–2019) was a major figure in the study of ancient Greek philosophy during the last decades of the twentieth century and the first of this. After teaching positions in London and Cambridge, where he became Laurence Professor, in 1996 he took up a Senior Research Fellowship at All Souls College, Oxford, from which he retired in 2006. In 2012 he published two volumes collecting essays dating from before the move to Oxford. Two new posthumously published volumes bring together essays from his years at All Souls and his retirement. The main body of Volume 3 presents studies written for a wide readership, first on Plato's Republic and then on the reading and interpretation of Plato in subsequent periods, particularly in nineteenth-century Britain. The volume also includes hitherto unpublished lectures, 'The Archaeology of Feeling', on the ancient origins of some key modern philosophical and psychological concepts.
Gender and Sexuality in Modern Japan
Authors: Frühstück Sabine
Published: March 2022

Gender and Sexuality in Modern Japan describes the ever-changing manifestations of sexes, genders, and sexualities in Japanese society from the 1860s to the present day. Analysing a wide range of texts, images and data, Sabine Frühstück considers the experiences of females, males and the evolving spectrum of boundary-crossing individuals and identities in Japan. These include the intersexed conscript in the 1880s, the first 'out' lesbian war reporter in the 1930s, and pregnancy-vest-wearing male governors in the present day. She interweaves macro views of history with stories about individual actors, highlighting how sexual and gender expression has been negotiated in both the private and the public spheres and continues to wield the power to critique and change society. This lively and accessible survey introduces Japanese ideas about modern manhood, modern womenhood, reproduction, violence and sex during war, the sex trade, LGBTQ identities and activism, women's liberation, feminisms and visual culture.
Decoupling
Authors: Michelson Ethan
Published: March 2022

Michelson's analysis of almost 150,000 divorce trials reveals routine and egregious violations of China's own laws upholding the freedom of divorce, gender equality, and the protection of women's physical security. Using 'big data' computational techniques to scrutinize cases covering 2009–2016 from all 252 basic-level courts in two Chinese provinces, Henan and Zhejiang, Michelson reveals that women have borne the brunt of a dramatic intensification since the mid-2000s of a decades-long practice of denying divorce requests. This book takes the reader upstream to the institutional sources of China's clampdown on divorce and downstream to its devastating and highly gendered human toll, showing how judges in an overburdened court system clear their oppressive dockets at the expense of women's lawful rights and interests. This book is a must-read for anyone interested in Chinese courts, judicial decision-making, family law, gender violence, and the limits and possibilities of the globalization of law.This title is also available as Open Access on Cambridge Core.
Shakespeare and British World War Two Film
Authors: Sullivan, Jr Garrett A.
Published: March 2022

During World War Two, many British writers and thinkers turned to Shakespeare in order to articulate the values for which their nation was fighting. Yet the cinema presented moviegoers with a more multifaceted Shakespeare, one who signalled division as well as unity. Shakespeare and British World War Two Film models a synchronic approach to adaptation that, by situating the Shakespeare movie within histories of film and society, avoids the familiar impasse in which the playwright's works are the beginning, middle and end of critical study. Through close analysis of works by Laurence Olivier, Leslie Howard, Humphrey Jennings, and the partners Michael Powell and Emeric Pressburger, among others, this study demonstrates how Shakespeare served as a powerful imaginative resource for filmmakers seeking to think through some of the most pressing issues and problems that beset wartime British society.
Marketing Democracy
Authors: Snider Erin A.
Published: March 2022

For nearly two decades, the United States devoted more than $2 billion towards democracy promotion in the Middle East with seemingly little impact. To understand the limited impact of this aid and the decision of authoritarian regimes to allow democracy programs whose ultimate aim is to challenge the power of such regimes, Marketing Democracy examines the construction and practice of democracy aid in Washington DC and in Egypt and Morocco, two of the highest recipients of US democracy aid in the region. Drawing on extensive fieldwork, novel new data on the professional histories of democracy promoters, archival research and recently declassified government documents, Erin A. Snider focuses on the voices and practices of those engaged in democracy work over the last three decades to offer a new framework for understanding the political economy of democracy aid. Her research shows how democracy aid can work to strengthen rather than challenge authoritarian regimes. Marketing Democracy fundamentally challenges scholars to rethink how we study democracy aid and how the ideas of democracy that underlie democracy programs come to reflect the views of donors and recipient regimes rather than indigenous demand.

River systems originating from the Upper Indus Basin (UIB) are dominated by runoff from snow and glacier melt and summer monsoonal rainfall. These water resources are highly stressed as huge populations of people living in this region depend on them, including for agriculture, domestic use, and energy production. Projections suggest that the UIB region will be affected by considerable (yet poorly quantified) changes to the seasonality and composition of runoff in the future, which are likely to have considerable impacts on these supplies. Given how directly and indirectly communities and ecosystems are dependent on these resources and the growing pressure on them due to ever‐increasing demands, the impacts of climate change pose considerable adaptation challenges. The strong linkages between hydroclimate, cryosphere, water resources, and human activities within the UIB suggest that a multi‐ and inter‐disciplinary research approach integrating the social and natural/environmental sciences is critical for successful adaptation to ongoing and future hydrological and climate change. Here we use a horizon scanning technique to identify the Top 100 questions related to the most pressing knowledge gaps and research priorities in social and natural sciences on climate change and water in the UIB. These questions are on the margins of current thinking and investigation and are clustered into 14 themes, covering three overarching topics of “governance, policy, and sustainable solutions”, “socioeconomic processes and livelihoods”, and “integrated Earth System processes”. Raising awareness of these cutting‐edge knowledge gaps and opportunities will hopefully encourage researchers, funding bodies, practitioners, and policy makers to address them.
Seasonal Variation and Governing Dynamics of the Mixed Layer in the Indian Sector of the Southern Ocean
Authors: Ferreira Azevedo Matheus , Aoki Shigeru , Kitade Yujiro
Published: March 2022

The dynamics involved in the variability of temperature, salinity, and density distributions in the upper layer of the Indo‐Pacific sector of the Southern Ocean were studied using Acoustic Doppler Current Profiler and Conductivity Temperature Depth data from a mini triangle trans‐ocean buoy network mooring deployed at 60°S and 140°E between January 15th and 19th December 2012, together with hydrographic casts, reanalysis outputs, and satellite imagery. Spectral analysis confirmed that near‐inertial internal waves are a major factor transporting energy downward to the lower boundary of the mixed layer (ML), with 12.5 J m−3 or 45% of the mean surface energy being able to reach deeper than the ML depth during one of the analyzed events. During a period of net heat loss from the ocean surface to the atmosphere, most of the energy was concentrated below the maximum shear layer, at around 80 m depth. Internal wave events were found to be linked to scalar diffusivity increases of up to two orders of magnitude. A box model clarified that surface cooling plays the most significant role in mixing surface waters during winter, but it is not enough to explain variability below 100 m depth, where horizontal advection and eddy enhancement are also important in modulating warm water flux. Our results elucidate how wind energy might enhance mixing, even in ice‐covered regions, while influencing depths greater than previously thought.

Dry lakebeds exposed by shrinking water bodies in arid regions constitute sodium (Na)‐rich mineral dust emission hotspots that may potentially affect agriculture through soil sodification. However, no soluble Na mass balance has so far been attempted. We modeled 13 years (2005–2017) of dust emission from Mar Chiquita (MC), the most extensive shrinking saline lake in South America. Based on a chemical characterization of dust, we found that a mean ∼15–150 mg m−2of soluble Na was deposited 300 km from the source during the season of strongest dust emissions. We estimated the impact of this atmospheric input on 13 agricultural soils, with different rainfall regimes and water holding capacities. At most sites, dust‐equilibrated infiltrated rainfall water had a Na concentration 8–7,000 times lower than the lowest concentration threshold proposed to trigger sodification. Additionally, this rainfall water is diluted ∼2–20 times as it infiltrates in saturated soils, and its sodium adsorption ratio is probably reduced due to the abundance of soluble calcium and magnesium in the soil solution. Thus, there is no risk of short‐term, seasonal sodification, except possibly at two sites and in close proximity to the dust source (<50 km), where dust deposition is maximum. At these sites, we estimated potential dust‐related rises in the proportion of soil exchangeable Na. Under scenarios of enhanced salt‐rich dust emissions from shrinking lakes in the twenty‐first century, agricultural soils close to salt‐rich dust sources worldwide should be monitored for potential Na enrichment related to Na‐rich dust.

Sub‐grid topographic heterogeneity has large impacts on surface energy balance and land‐atmosphere interactions. However, the impacts of representing sub‐grid topographic effects in land surface models (LSMs) on surface energy balance and boundary conditions remain unclear. This study analyzed and evaluated the impacts of sub‐grid topographic representations on surface energy balance, turbulent heat flux, and scalar (co‐)variances in the Energy Exascale Earth System Model (E3SM) land model (ELM). Three sub‐grid topographic representations in ELM were compared: (a) the default sub‐grid structure (D), (b) the recently developed sub‐grid topographic structure (T), and (c) high spatial resolution (1KM). Additionally, two different solar radiation schemes in ELM were compared: (a) the default plane‐parallel radiative transfer scheme (PP) and (b) the parameterization scheme (TOP) that accounts for sub‐grid topographic effects on solar radiation. A series of offline simulations with the three grid discretization structures (D, T, and 1KM) and two schemes of solar radiation (TOP and PP) were carried out using the Sierra Nevada, California. 1KM simulations with TOP well capture the spatial heterogeneity of surface fluxes compared to Moderate Resolution Imaging Spectroradiometer remote sensing data. There are significant differences between TOP and PP in the 1‐km simulated surface energy balance, but the differences in mean values and standard deviations become small when aggregated to the grid scale (i.e., 0.5°). The T configuration better mimics the 1KM simulations with TOP than the D configuration and better captures the sub‐grid topographic effects on surface energy balance and boundary conditions. These results underline the importance of representing sub‐grid topographic heterogeneities in LSMs and motivate future research to understand the sub‐grid topographic effects on land‐atmosphere interactions over mountainous areas.

The Dora‐Maira massif is an archetypal nappe stack of subducted and exhumed upper crust. Slices of continental crust experienced metamorphism at upper blueschist to ultrahigh‐pressure (UHP) eclogite‐facies conditions. While the timing of peak metamorphism in the UHP unit has been extensively studied, little is known about the other units. In order to constrain the timing and conditions of high‐pressure metamorphism, U‐Pb‐trace element analyses of rutile and titanite were carried out across the nappe stack. The data reveal Alpine peak metamorphic ages younging downwards in the stack, from ∼40 to ∼33 Ma. Greenschist‐facies retrogression of the whole massif occurred at ∼32–31 Ma, after high‐pressure metamorphism of the lowermost unit (Sanfront‐Pinerolo Unit). Tectonic implications include (a) continuous and fast exhumation of subducted continental crust, (b) long‐lived subduction from ∼60 to ∼33 Ma of the distal European margin, reconstructed to be a hyperextended margin spread over ∼130 km for the Dora‐Maira massif alone, and (c) the initiation of continental collision synchronous with the end of high‐pressure metamorphism.
Resonance Maps for 3D Alfvén Waves in a Compressed Dipole Field

Published: March 2022

Resonance Maps depict the possible locations and polarizations of resonant Alfvén waves (Field Line Resonances – FLRs) for a given equilibrium and driving frequency. Previously the use of Resonance Maps has been developed for gaining insight into the behavior of Alfvén waves in basic potential magnetic fields that allow the use of an orthogonal field aligned coordinate system. In more general magnetic fields these coordinates do not exist. In this paper we explore the application of Resonance Maps to such equilibria. A number of simulations of resonant Alfvén waves are presented and interpreted using the Maps. We find that Resonance Maps remain useful when some of the constructions used previously are generalised to accommodate the properties of more general magnetic fields. For example, Resonance Maps are able to predict the location and polarisation of Alfvén waves which are driven strongly by fast mode waves using a “tangential alignment condition”. Unusual properties, such as Alfvén waves crossing flux surfaces persist in the more general magnetic fields we consider.

Solving the doping asymmetry issue in wide-gap semiconductors is a key difficulty and long-standing challenge for device applications. Here, a desorption-tailoring strategy is proposed to juggle the carrier concentration and transport. Specific to the p-doping issue in Al-rich AlGaN, self-assembled p-AlGaN superlattices with an average Al composition of over 50% are prepared by adopting this approach. The hole concentration as high as 8.1 × 1018 cm−3 is thus realized at room temperature, which is attributed to the significant reduction of effective Mg activation energy to 17.5 meV through modulating the activating path, as well as the highlighted Mg surface-incorporation by an intentional interruption for desorption. More importantly, benefiting from the constant ultrathin barrier thickness of only three monolayers via this approach, vertical miniband transport of holes is verified in the p-AlGaN superlattices, greatly satisfying the demand of hole injection in device application. 280 nm deep-ultraviolet light-emitting diodes are then fabricated as a demo with the desorption-tailored Al-rich p-AlGaN superlattices, which exhibit a great improvement of the carrier injection efficiency and light extraction efficiency, thus leading to a 55.7% increase of the light output power. This study provides a solution for p-type doping of Al-rich AlGaN, and also sheds light on solving the doping asymmetry issue in general for wide-gap semiconductors.

Poly (ADP-ribose) polymerase (PARP) inhibitor (PARPi) resistance remains a therapeutic challenge in ovarian cancer. High-mobility group box 3 (HMGB3) plays significant roles in the development of drug resistance of many cancers. However, the function of HMGB3 in PARPi resistance is poorly understood. In the current study, we clarified that HMGB3 was aberrantly overexpressed in high-grade serous ovarian carcinoma (HGSOC) tissues, and high HMGB3 levels indicated shorter overall survival and drug resistance in HGSOC. The overexpression of HMGB3 increased the insensitivity of ovarian cancer to PARPi, whereas HMGB3 knockdown reduced PARPi resistance. Mechanistically, PARP1 was identified as a novel interaction partner of HMGB3, which could be blocked using olaparib and was enhanced upon DNA damage conditions. We further showed that loss of HMGB3 induced PARP1 trapping at DNA lesions and inhibited the PARylation activity of PARP1, resulting in an increased DNA damage response and cell apoptosis. The PARPi-resistant role of HMGB3 was also verified in a xenograft mouse model. In conclusion, HMGB3 promoted PARPi resistance via interacting with PARP1, and the targeted inhibition of HMGB3 might overcome PARPi resistance in ovarian cancer therapy.
