The Positive Effect of Women’s Education on Fertility in Low-Fertility China
Authors: Chen Shuang
Published: February 2022

Despite pervasive evidence of more educated women having lower fertility, it remains unclear whether education reduces women’s fertility. This study presents new evidence of the causal effect of women’s education on fertility from China, where fertility has remained below the replacement level since the early 1990s. To account for endogeneity, the study exploits the timing and varying intensity of China’s higher education expansion as exogenous sources of increase in women’s education. Using data from China General Social Survey (2010–2012), findings show that each year of women’s education induced by the higher education expansion increases the number of children ever born by 10%. According to the average marginal effects, each additional year of women’s education increases the number of children ever born by 0.14, decreases the probability of having no children by 3 percentage points, and increases the probability of having two or more children by 4 percentage points. Two mechanisms drive the positive effect of education: first, education does not cause an increase in the mean age at first marriage; second, among ever-married women, education increases their demand for children. Findings from this study have important implications for China and other low-fertility developing countries.
Gestational Age in Autistic Children and Adolescents: Prevalence and Effects on Autism Phenotype
Authors: Martini Miriam I. , Merkelbach Inge , Begeer Sander
Published: February 2022

Pre- and post-term children show increased autism risk. Little is known about gestational age (GA) prevalence among autistic children, and their respective autism phenotype. We compared prevalence of pre-, full- and post-term birth between a population-derived sample of N = 606 (137 females, 22.61%) autistic children and adolescents (mean age = 14.01, SD = 3.63, range 3–24) from the Netherlands Autism Register, and matched controls from the Dutch birth register. Autism phenotype and comorbid symptoms were assessed with the AQ-short and SDQ questionnaires. Using logistic regression, we found higher prevalence of pre- and post-term birth among autistic individuals but no phenotypical differences across GA groups. Autism risk was particularly elevated for post-term children, highlighting the need for closer investigation of autism on the whole GA range.
Debt Problem of One Partner and Depressive Morbidity in the Other: A 2-Year Follow-up Register Study of Different-Sex Couples in Sweden
Authors: Rojas Yerko
Published: February 2022

This study sets out to examine whether depressive morbidity varies by status of financial indebtedness of a spouse or cohabiting partner. For this purpose, individuals aged between 20 and 60 with a different-sex spouse/cohabiting partner with a registration date for a debt at the Swedish Enforcement Authority (SEA) during 2017 (n = 6979) are followed-up for a 2-year period for prescriptions of antidepressants and compared with a sample from the general Swedish population (n = 29,708). The analysis is based on penalized maximum likelihood logistic regressions. Both women and men were more likely to suffer from depressive morbidity if the spouse/cohabiting partner had been registered at the SEA in 2017 and was still active for a debt in the SEA’s register in 2018 (OR 1.31 and OR 1.57, respectively), irrespective of their own health, employment, socioeconomic status, and other background variables. This also held true for men if a wife/cohabiting partner had been registered at the SEA in 2017 but was no longer active for a debt in the SEA’s register in 2018 (OR 1.29). For women, on the other hand, only those with no history (11-year period) of prescription of psychotropic medications were also at an enhanced risk of depressive morbidity if a husband/cohabiting partner had gone from being registered for a debt at the SEA in 2017, to not being registered as active for a debt in the SEA’s register in 2018 (OR 1.24). The results reinforce the importance of acknowledging that negative effects of financial indebtedness extend beyond the individual debtor.
The role of adult noctuid moths (Lepidoptera: Noctuidae) and their food plants in a nocturnal pollen-transport network on a Mediterranean island
Authors: Ribas-Marquès Elisa , Díaz-Calafat Joan , Boi Marzia
Published: February 2022

Noctuidae belong to one of the largest families of night-flying Lepidoptera. However, despite being among the most common nocturnal flower-visitors, they have seldom been included in pollination networks. Similarly, the current knowledge on food plants used by adults is rather scarce. In this article, we build the first moth–plant pollen transfer network in the Balearic archipelago. We aim to increase the knowledge of which plants are used as food resources by adult Noctuidae, assess how specific or generalist nocturnal pollinators and their food plants are and establish the first baseline information on adult Noctuidae–plant interactions on the archipelago and the Mediterranean. 20.7% of the adult Noctuidae in our samplings carried pollen and were therefore potentially involved in nocturnal pollination. The family Ericaceae, and especially Arbutus unedo, was a key food resource for our moth community, with 46% of the total recorded interactions belonging to this plant. Overall, both plants and moths in our system behaved in a generalist way. Niche overlap was larger in moths than in plants, suggesting that the functional role that moth species take in our system is more redundant than that taken by plants. Robustness values suggest that the network functionality would not collapse despite the extinction of a few species.

Implications for insect conservation

Detecting flower preferences and the role of nocturnal insects on pollination will allow understanding of ecosystem functionality and will be crucial for conservation of both moths and organisms that depend on them.

Bioactive materials in combination with antibiotics have been widely developed for the treatment of bone infection. Thus, this work aims to characterize six biomaterials formulated with different concentrations of hydroxyapatite and cobalt ferrite nanoparticles, in addition to the antibiotic ciprofloxacin, using X-ray diffraction (XRD), scanning electron microscopy (SEM), and the antibiotic diffusion test on agar. Furthermore, in vivo biocompatibility and the reabsorption process of these materials were analyzed. XRD showed that both hydroxyapatite and cobalt ferrite present high crystallinity. The photomicrographs obtained by SEM revealed that composites have a complex surface, evidenced by the irregular arrangement of the hydroxyapatite and cobalt ferrite granules, besides demonstrating the interaction between their components. The antibiotic-diffusion test showed that all biomaterials produced an inhibition halo inStaphylococcus aureuscultures. For the biocompatibility study, composites were surgically implanted in the dorsal region of rabbits. At 15, 30, 70, and 100 days, biopsies of the implanted regions were performed. The biomaterials were easily identified during histological analysis and no significant inflammatory process, nor histological signs of toxicity or rejection by the adjacent tissue were observed. We can conclude that the biomaterials analyzed are biocompatible, degradable, and effective in inhibiting the in vitro growth ofStaphylococcus aureus.
Micro-XRF-inferred depositional history of the Orakei maar lake sediment sequence, Auckland, New Zealand
Authors: Peti Leonie , Augustinus Paul C.
Published: February 2022

Lake sediment records offer insights into past climate and environmental changes. There are, however, few continuous lake sediment records from the Southern Hemisphere mid-latitudes that span the last glacial interval (LGI) and have the requisite chronological control and sampling resolution. Orakei maar paleolake in the Auckland Volcanic Field, New Zealand, is an exception, as it contains a high-resolution record of continuous lacustrine sedimentation from its formative phreatomagmatic eruption ~ 130 ka, until post-glacial sea-level rise breached the crater tuff rim and connected the lake to the sea ~ 9 ka. We used micro-XRF core scanning, dry bulk density, loss-on-ignition and visual facies descriptions to investigate the depositional history of Orakei maar lake as a response to regional and global drivers of climate change, and to erosional events in the lake catchment. The climate history of the lake was divided into six depositional phases: (I) Early warming with frequent in-wash events, followed by climate fluctuations coeval with marine isotope stages (MIS) 5e to mid-5c, (II) Warm, quiescent depositional conditions during mid-MIS 5c to 5a, (III) A colder, windier interval during MIS 4, (IV) Warmer conditions with dominantly autochthonous sedimentation during MIS 3, (V) Cold conditions followed by a slow temperature increase and the onset of sea-level rise during late MIS 2, (VI) Warm conditions that culminated in formation of a peat unit at the top of the Orakei lacustrine sediment sequence, which was terminated by an influx of massive marine muds into the basin at 9.75 ka. Comparison of the inferred climate evolution at Orakei with climate inferences from the global marine benthic MIS record during LGI shows general agreement, though inferred climate changes consistently occur earlier at Orakei than in the MIS. There is also general agreement in temperature changes inferred from the Orakei record and from other regional lake sediment records, but more detailed comparison requires additional proxy climate data such as pollen, organic geochemistry and biomarkers, to better understand discrepancies between some records. This study demonstrated the great potential of the Orakei record for paleoclimate inference and the applicability of micro-XRF core scanning data for addressing questions about paleoclimate and paleoenvironment. It also highlighted past intervals that require further study.
Diffusion-Localization Transition Point of Gravity Type Transport Model on Regular Ring Lattices and Bethe Lattices
Authors: Koike Hajime , Takayasu Hideki , Takayasu Misako
Published: February 2022

Focusing on the diffusion-localization transition, we theoretically analyzed a nonlinear gravity-type transport model defined on networks called regular ring lattices, which have an intermediate structure between the complete graph and the simple ring. Exact eigenvalues were derived around steady states, and the values of the transition points were evaluated for the control parameter characterizing the nonlinearity. We also analyzed the case of the Bethe lattice (or Cayley tree) and found that the transition point is 1/2, which is the lowest value ever reported.
Unemployment and Well-Being of Europeans Across the Life Cycle: The Role of Countries’ Macroeconomic Situation
Authors: Malisauskaite Gintare , Nizalova Olena , Xanthopoulou Despoina
Published: February 2022

Unemployment impairs individuals’ well-being and health and there is some empirical evidence showing that macroeconomic conditions can moderate these effects. This paper goes a step further and investigates differences in how macroeconomic indicators of European countries’ economic situation relate to individual subjective health and well-being, and also moderate the relationship between individual labour market exclusion and these outcomes across age groups: young individuals (aged 15–29), prime working age adults (aged 30–49, base category) and pre-retirement age adults (aged 50–64). We used two different macroeconomic indicators to define macroeconomic situation: country-level unemployment rate and gross domestic product (GDP). Both indicators were disaggregated into long-term economic trend and business cycle shocks using Hodrick–Prescott filtering to allow distinguishing between expected and unexpected change in macroeconomic circumstances. We used the European Social Survey individual-level data from 35 European countries for 2002–2014. Multi-level analysis with three levels were run for men and women separately. Results revealed differences in how individual-level unemployment related to well-being depending on the age group, with pre-retirement age group adults’ health and well-being suffering the most. Also, macroeconomic indicators were found to moderate the relationship between individual-level unemployment and subjective health and well-being with some noticeable differences between age groups, and with GDP trend having the most sizeable influence.
Creation of Work Integration Social Enterprises (WISEs) by Social Action Organizations: Proposal of a Model for Decision-Making
Authors: Pizarro Escribano Francisco , Miranda González Francisco Javier
Published: February 2022

Successive crisis in Europe have contributed to rethink welfare state and the entrepreneurial role of Third Sector organizations in the provision of community services that progressively have created social enterprises. Its creation is the result of a decision-making process that is collective, not individual, and of a strategic nature, in which the organization's culture plays a relevant role. This work aims to describe and analyze the entrepreneurial process, and the key elements that determines the decision of creating a work insertion social enterprise by its promotor entity. As a result, this article proposes an explicative model of social enterprises creation and makes an empirical validation, using Delphi Method in Spanish work insertion social enterprises case.
Family Cohesion and Sleep Disturbances During COVID-19: the Mediating Roles of Security and Stress
Authors: Ye Baojuan , Hu Jing , Im Hohjin , Liu Mingfan , Wang Xinqiang , Yang Qiang
Published: February 2022

Despite the increase in proximity to one's family amid university closures during the COVID-19 pandemic, the mechanisms underlying how family cohesion influenced students’ sleep remain understudied. Using a large sample of college students in China (N = 1,178) during the COVID-19 pandemic, the current study examined the serial mediating roles of sense of security and perceived stress on the effect of family cohesion on sleep disturbance. Generalized linear modeling serial mediation analysis with 1,000 resampled bootstrapping methods showed that sense of security and perceived stress were negatively and positively associated with sleep disturbance, respectively. Furthermore, sense of security and perceived stress fully mediated the indirect effect of family cohesion on sleep disturbances. Implications and conclusions are discussed.
Patient Advocacy Assessment in the Medicine Clerkship: A Qualitative Study of Definition, Context, and Impact
Authors: Griffiths Elizabeth P. , Lai Cindy J. , Ziv Tali , Dawson Deanna , Dhaliwal Gurpreet , Wheeler Margaret , Teherani Arianne
Published: February 2022

Background

Advocacy is a core value of the medical profession. However, patient advocacy (advocacy) is not uniformly assessed and there are no studies of the behaviors clinical supervisors consider when assessing advocacy.

Objective

To explore how medical students and supervisors characterize advocacy during an internal medicine clerkship, how assessment of advocacy impacted students and supervisors, and elements that support effective implementation of advocacy assessment.

Design

A constructivist qualitative paradigm was used to understand advocacy assessment from the perspectives of students and supervisors.

Participants

Medical students who completed the internal medicine clerkship at UCSF during the 2018 and 2019 academic years and supervisors who evaluated students during this period.

Approach

Supervisor comments from an advocacy assessment item in the medicine clerkship and transcripts of focus groups were used to explore which behaviors students and supervisors deem to be advocacy. Separate focus groups with both students and supervisors examined the impact that advocacy assessment had on students’ and supervisors’ perceptions of advocacy and what additional context was necessary to effectively implement advocacy assessment.

Key Results

Students and supervisors define advocacy as identifying and addressing social determinants of health, recognizing and addressing patient wishes and concerns, navigating the health care system, conducting appropriate evaluation and treatment, and creating exceptional therapeutic alliances. Effective implementation of advocacy assessment requires the creation of non-hierarchical team environments, supervisor role modeling, and pairing assessment with teaching of advocacy skills. Inclusion of advocacy assessment reflects and dictates institutional priorities, shapes professional identity formation, and enhances advocacy skill development for students and their supervisors.

Conclusions

Students and supervisors consider advocacy to be a variety of behaviors beyond identifying and addressing social determinants of health. Effectively implementing advocacy assessment shapes students’ professional identity formation, underscoring the critical importance of formally focusing on this competency in the health professions education.
Pathophysiology of Demineralization, Part I: Attrition, Erosion, Abfraction, and Noncarious Cervical Lesions
Authors: Roberts W. Eugene , Mangum Jonathan E. , Schneider Paul M.
Published: February 2022

Purpose of the Review

Compare pathophysiology for infectious and noninfectious demineralization disease relative to mineral maintenance, physiologic fluoride levels, and mechanical degradation.

Recent Findings

Environmental acidity, biomechanics, and intercrystalline percolation of endemic fluoride regulate resistance to demineralization relative to osteopenia, noncarious cervical lesions, and dental caries.

Demineralization is the most prevalent chronic disease in the world: osteoporosis (OP) >10%, dental caries ~100%. OP is severely debilitating while caries is potentially fatal. Mineralized tissues have a common physiology: cell-mediated apposition, protein matrix, fluid logistics (blood, saliva), intercrystalline ion percolation, cyclic demineralization/remineralization, and acid-based degradation (microbes, clastic cells). Etiology of demineralization involves fluid percolation, metabolism, homeostasis, biomechanics, mechanical wear (attrition or abrasion), and biofilm-related infections. Bone mineral density measurement assesses skeletal mass. Attrition, abrasion, erosion, and abfraction are diagnosed visually, but invisible subsurface caries <400μm cannot be detected. Controlling demineralization at all levels is an important horizon for cost-effective wellness worldwide.

Published: February 2022

We describe the techniques applied by the University of Alberta (UA) team in the most recent Competition on Legal Information Extraction and Entailment (COLIEE 2021). We participated in retrieval and entailment tasks for both case law and statute law; we applied a transformer-based approach for the case law entailment task, an information retrieval technique based on BM25 for legal information retrieval, and a natural language inference mechanism using semantic knowledge applied to statute law texts. This competition included 25 teams from 14 countries; our case law entailment approach was ranked no. 4 in Task 2, the BM25 technique for legal information retrieval was ranked no. 3 in Task 3, and the natural language inference technique incorporating semantic information was ranked no. 4 in Task 4. The combination of the latter two techniques on Task 5 was ranked no. 2. We also performed error analysis of our system in Task 4, which provides some insight into current state-of-the-art and research priorities for future directions.
Testosteron door de eeuwen

Published: February 2022

Samenvatting

De zoektocht naar het mannelijk hormoon begint met de experimenten van de Duitse fysioloog Bertholdt in 1849 die testes van een kuiken transplanteerde in gecastreerde kuikens en het gedrag van deze kippen beschreef voor en na de ingreep. Na de ontdekkingen van de effecten van extracten van organen nam de organotherapie, het genezen van ziekten met orgaanextracten, een grote vlucht. Injecties met dierlijke testesextracten, sterilisaties om de productie van mannelijk hormoon te stimuleren en testestransplantaties werden populair, omdat ze mogelijk veroudering en seksuele stoornissen konden tegengaan. De interesse in de effecten van deze behandelingen leidde ertoe dat vele onderzoeksgroepen, gesteund door de farmaceutische industrie, androgenen isoleerden uit de testes en urine. Ernst Laqueur (1866–1947) en zijn medewerkers isoleerden in 1935 als eersten testosteron.

Published: February 2022

The germination characteristics response for some selected maize hybrids and their parental inbred lines were observed and evaluated in an in vitro trial. The aim of the study was to determine the differences within the performance of some hybridization pathways. Single cross (SC), double cross (DC) and three-way cross (TC) hybrids and their parental inbred lines were studied. The results showed that the germination of maize seeds started after the third day and completely germinated on the seventh day after sowing. Hybrids SC (F1), DC (F1), and TC (F1) showed excellent germination performance with a 100% germination rate on the fifth day and produced the highest shoot and root lengths with 7.9 cm, 7.6 cm, and 6.9 cm (shoot length) and 12.9 cm, 13.9 cm and 14.9 cm (root length), respectively. Thus, the results obtained clearly show that the hybrid seeds have higher germination rate (100%), and the seedlings were more vigorous compared to the parents.
Research on ADR1s helps understanding the plant immune network
Authors: Hu Meijuan , Zhou Jian-Min
Published: February 2022

Plant innate immunity begins with the recognition of pathogens by plasma membrane localized pattern-recognition receptors (PRRs) and intracellular nucleotide-binding domain leucine-rich repeat containing receptors (NLRs), which lead to pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), respectively. For a long time, PTI and ETI have been regarded as two independent processes although they share multiple components and signal outputs. Increasing evidence shows an intimate link between PTI and ETI. PTI and ETI mutually potentiate each other, and this is essential for robust disease resistance during pathogen infection. An ancient class of NLRs called RNLs, so named because they carry a Resistance to Powdery Mildew 8 (RPW8)-like coiled-coil (CC) domain in the N terminus, has emerged as a key node connecting PTI and ETI. RNLs not only act as helper NLRs that signal downstream of sensor NLRs, they also directly mediate PTI signaling by associating with PRR complexes. Here, we focus on Activated Disease Resistance 1 (ADR1), a subclass of RNLs, and discuss its role and mechanism in plant immunity.
Magnesium Isotopes
Authors: Tipper Edward T.
Published: February 2022

Magnesium is a major constituent in silicate and carbonate minerals, the hydrosphere and the biosphere. Magnesium is constantly cycled between these reservoirs. Since each of the major planetary reservoirs of magnesium have different magnesium isotope ratios, there is scope to use magnesium isotope ratios to trace 1) the processes that cycle Magnesium at a spatial scales from the entire planet to microscopic and 2) the relative fluxes between these reservoirs. This review summarises some of the key motivations, successes and challenges facing the use of magnesium isotopes to construct a budget of seawater magnesium, present and past.
The Case Study in Archaeological Theory
Authors: Lucas Gavin , Olsen Bjørnar
Published: February 2022

The case study is a familiar yet generally taken-for-granted element of archaeological theory. Typically, it is viewed as a kind of “proof of concept,” an essential way to demonstrate the value of a particular theoretical approach, if not theory in general. In this article, we examine the case study as it has been used in archaeology, exploring its different manifestations and situating them within a wider discussion of the role of cases and examples within the humanities and social sciences. Offering our own “example”—a rereading of Bonnichsen's Millie's Camp experiment from the 1970s—we argue for a different role of the case study in relation to archaeological theory.
Wave scattering by a three-dimensional submerged horizontal rectangular plate in a channel: experiments and numerical computations
Authors: Geng T. , Liu H. , Wang Q. , Dias F.
Published: February 2022

Experiments are conducted in a wave tank to investigate wave scattering by a three-dimensional submerged horizontal rectangular plate in a channel. The free-surface elevation around the plate is presented for various water depths and depths of submergence of the plate. The wave forces and moments are obtained using an underwater load measuring system. The numerical simulations are performed with a parallelized three-dimensional boundary element method. The numerical set-up follows closely the set-up of the laboratory experiments. The numerical results are compared with the experimental results for non-breaking waves. In most cases a good agreement is found for the free-surface elevation, the vertical force and the moment. A physical interpretation of the flow around the plate is provided. The pressure distribution on the lower surface of the plate differs from the linear distribution from the leading edge to the trailing edge that is obtained in the equivalent two-dimensional problem. The reflection by the lateral walls is investigated.
Multipolar spherical and cylindrical vortices
Authors: Viúdez A.
Published: February 2022

Multipolar spherical solutions to the three-dimensional steady vorticity equation are provided. These solutions are based on the separation of radial and angular contributions in terms of the spherical Bessel functions and vector spherical harmonics, respectively. In this set of multipolar vortex solutions, the Hicks–Moffatt swirling vortex is categorized as a vortex of degree

${\ell }=1$

and therefore as a vortex dipole. This swirling vortex is the three-dimensional dipole in spherical geometry equivalent to the two-dimensional Lamb–Chaplygin dipole in polar geometry. The three-dimensional dipole solution admits two linearly superposable solutions. The first one is a Trkalian flow and the second one is a cylindrical solid-body rotation with swirl. The higher

${\ell }>1$

multipolar vortices found are either vanishing-helicity vortices or Trkalian flow vortices. The multipolar Trkalian flows admit two circular polarizations given by the sign of the wavenumber

$k$

. It is also found that piecewise vortex solutions, consisting of interior rotational and exterior potential flow domains, satisfying velocity continuity conditions at the vortex boundary, are possible in the general multipolar Trkalian spherical vortex. A particular polarized dipole solution in three-dimensional cylindrical geometry, consisting as well in the superposition of a Trkalian flow and a rigid motion, is also analysed. This swirling vortex may be interpreted as the three-dimensional dipole in cylindrical geometry equivalent to the two-dimensional Lamb–Chaplygin dipole in polar geometry.
A live yeast supplementation to gestating ewes improves bioactive molecule composition in colostrum with no impact on its bacterial composition and beneficially affects immune status of the offspring

Published: February 2022

Colostrum quality is of paramount importance in the management of optimal ruminant growth and infectious disease prevention in early life. Live yeast supplementation effect during the last month of gestation was evaluated on ewes’ colostrum composition. Two groups of ewes (n = 14) carrying twin lambs were constituted and twins were separated into groups (mothered or artificially fed) 12 h after birth. Nutrient, oligosaccharides (OS), IgG and lactoferrin concentrations were measured over 72 h after lambing, and bacterial community was described in colostrum collected at parturition (T0). Immune passive transfer was evaluated through IgG measurement in lamb serum. In both groups, colostral nutrient, OS concentrations and IgG concentrations in colostrum and lamb serum decreased over time (P < 0⋅01), except for lactose, which slightly increased (P < 0⋅001), and lactoferrin, which remained stable. Bacterial population was stable over time with high relative abundances of Aerococcaceae, Corynebacteriaceae, Moraxellaceae and Staphylococcaceae in T0 colostrum. No effect of supplementation was observed in nutrient and lactoferrin concentrations. In supplemented ewes, the level of colostral IgG was higher at T0 and a higher level of serum IgG was observed in lambs born from supplemented mothers and artificially fed, while no effect of supplementation was observed in the mothered lamb groups. Using a metabolomic approach, we showed that supplementation affected OS composition with significantly higher levels of colostral Neu-5Gc compounds up to 5 h after birth. No effect of supplementation was observed on bacterial composition. Our data suggest that live yeast supplementation offsets the negative impact of early separation and incomplete colostrum feeding in neonate lambs.
¡Despierta México! Changing Public Attitudes Toward NAFTA, 2008–2018
Authors: Aspinwall Mark , Maldonado Gerardo
Published: February 2022

Regional trade agreements have important consequences for developing countries, but the public opinion literature on trade agreements suffers from several shortcomings. Most significant is that studies tend to take a single year as the point of analysis, leaving us uncertain as to how opinion evolves. This study uses polling data to examine Mexicans’ attitudes toward NAFTA over a ten-year period. Results from regression analyses show an association between Mexicans’ support for the United Nations and their support for NAFTA, and a weaker relationship for other types of cues (presidential, the United States), than other studies have found. The data also reveal an association between Donald Trump’s arrival in the presidency and increased support for NAFTA.
Partisan External Borrowing in Middle-Income Countries
Authors: Cormier Ben
Published: February 2022

Why do middle-income country governments use costlier sovereign debt markets when cheaper finance is available from official creditors? This research note argues that left-leaning governments with labor and the poor as core constituencies are likely to prioritize markets in their annual foreign borrowings. This is because markets provide an exit option from official creditor conditions that have disproportionately negative effects on working classes. This finding puts limits on disciplinary assumptions that left-leaning governments should have relatively less access to sovereign debt markets and thus use them less. Instead, left-leaning middle-income countries are likely to use proportionally more market finance as they fulfill annual foreign borrowing needs. This, in turn, shapes which middle-income countries are likely to become relatively more exposed to global debt market costs and pressures as they accumulate external debt over time.
Evolution of soil fertility research and development in Ethiopia: From reconnaissance to data-mining approaches
Authors: Erkossa Teklu , Laekemariam Fanuel , Abera Wuletawu , Tamene Lulseged
Published: February 2022

Meeting the burgeoning global demand for both food and energy requires substantial yield increases through the efficient use of inputs like fertilizers. Prompted by the result of a soil survey expedition in the late 1950s, which signaled a widespread deficiency of nitrogen (N) and phosphorus (P), plant nutrition research in Ethiopia began in the 1960s, focusing on the response of prioritized cereals – tef (Eragrostis tef), wheat (Triticum aestivum), and maize (Zea mays) – to the application of N and P fertilizers. Nationwide on-farm trials conducted in the early 1970s led to a blanket recommendation of 64 kg N ha−1 and 20 kg P ha−1, irrespective of the crop and soil types, which were applied in the form of di-ammonium phosphate (18-46-0) and urea (46-0-0), respectively. Research conducted in the 1980s across agro-ecological and edaphic spectrum recommended 30–138 kg N ha−1 and 0–50 kg P ha−1, respectively. However, studies show that only 30–40% of the smallholder farmers use fertilizers at a rate less than recommended (on average at 37–40 kg ha−1). This rate reflects limited supply, high prices, and the low and declining crop response to fertilizers. As a result, cereal yields increased only 10% despite a fivefold increase in fertilizer application since the 1980s. Owing to the limited and declining crop response and the increased price of fertilizer in the 1990s, research on the integrated application of inorganic and organic sources of fertilizers was initiated. Although the integrated use resulted in increased yield and better economic benefits, it was not mainstreamed into the national agricultural extension system. The soil survey expedition that began in 2011 culminated in the mapping of the soil nutrient status using literature-based critical limits. The maps have persistently revealed the deficiency of N, P, potassium, sulfur, zinc, and boron across the surveyed areas. Despite the above efforts, the data sets generated through the soil surveys conducted at different times during the last half-century and the agronomic research during the same period have never been fully exploited. It is believed that the recent development in data mining and machine-learning approaches creates the opportunities to use the data sets in conjunction with other covariates in order to generate evidence that helps to make better decisions both at strategic and operational levels. The development of decision support tools based on such large datasets and analytical capacity is believed to facilitate better-informed decisions that lead to increased resource use efficiency and sustainability.
Low-cost seed storage technologies for development impact of small-scale seed saving entities in tropical climates
Authors: Trail Patrick , Motis Timothy , Swartz Stacy , Bicksler Abram
Published: February 2022

Seeds can deteriorate rapidly under high heat and humidity, making it challenging and potentially costly to store orthodox seeds effectively in the tropics, thereby affecting agriculture development. This work explores the effectiveness of novel, low-cost technologies for storing seeds in warm, humid, resource-constrained environments, focusing on maintaining the viability of seeds already dry prior to storage. Seeds of okra (Abelmoschus esculentus (L.) Moench), sorghum (Sorghum bicolor (L.) Moench), and velvet bean (Mucuna pruriens (L.) DC) were kept for 12 months under roofed, outdoor screened porches. Seed moisture content prior to treatment was 6, 9, and 12% for okra, sorghum, and velvet bean, respectively. Treatments, replicated four times at each of two locations (USA [Florida] and Thailand), were technology suites involving vacuum drawn on glass jars with a modified bicycle pump, vacuum drawn on polyethylene bags with an electric vacuum sealing machine, desiccant (calcium oxide powder or zeolite Drying Beads® at a 2:1 ratio, by weight, of seeds to desiccant) in glass jars, and nontreated seeds in paper bags. Ambient temperature and humidity were variable and high, reaching over 35 °C and 83%, respectively, at both locations. Under these conditions, okra and sorghum germination percentages (across locations) without treatment declined from over 90% initially to 30 and 0%, respectively, by month 12. Both vacuum treatments and calcium oxide maintained high germination of okra (≈ 80%) and velvet bean seeds (nearly 100%) across locations. Glass, however, was superior to polyethylene in maintaining vacuum and stabilizing the moisture content of okra and sorghum seeds. Only zeolite reduced seed moisture below initial values, drying seeds to ultradry levels of <5%. With zeolite, sorghum germination stayed near 70% over time, while okra and velvet bean germination fell to <40 and <20%, respectively, by month 12, suggesting that, with the beads kept with dry seeds in storage rather than removing the beads after reaching a target level of seed moisture, the 2:1 ratio of seed-to-bead weight was too high for seeds that are sensitive to ultralow moisture. Findings have practical implications for inexpensive household- or community-level seed storage to deliver development impact.

Bullying victimization is common in adolescence and has been associated with a broad variety of psychopathology and alcohol use. The present study assessed time-varying associations between bullying victimization and alcohol use through internalizing and externalizing symptoms and whether this indirect association throughout time is moderated by personality. This 5-year longitudinal study (3,800 grade 7 adolescents) used Bayesian multilevel moderated mediation models: independent variable was bullying victimization; moderators were four personality dimensions (anxiety sensitivity, hopelessness, impulsivity, and sensation seeking); internalizing symptoms (anxiety, depressive symptoms) and externalizing symptoms (conduct, hyperactivity problems) were the mediators; and alcohol use, the outcome. Results indicated significant between, within, and lagged effects on alcohol use through internalizing and externalizing symptoms. There were significant between and within effects on alcohol use through internalizing symptoms for adolescents with high anxiety sensitivity and hopelessness, and significant between, within, and lagged effects on alcohol use through externalizing symptoms for adolescents with high impulsivity and sensation seeking. These findings implicate two risk pathways that account for how bullying victimization enhances alcohol use risk and emphasize the importance of personality profiles that can shape the immediate and long-term consequences of victimization.
Kulturand Its Ambiguities: West German Intellectuals and the Société Européenne de Culture in the Early 1950s
Authors: Guidali Fabio
Published: February 2022

This article provides a perspective on the relations between Jaspers, Sternberger and Paeschke, and the SEC, an intellectual organisation which advocated the autonomy of culture from politics and the idea of common cultural ground with Eastern Europe. While West German intellectuals could endorse the principles of the association, they were reluctant to cooperate with foreign colleagues to bridge the division of Europe. This article supposes that their failure to collaborate with the SEC was due to the existence of a limited space for independent political initiatives, but also to their actual approval of the Cold War status, which had brought them back into the international community, and to the persistence of a traditional interpretation of ‘culture’, regardless of whether they accepted or refused this. Thus, the Cold War situation is not the only explanation of why the SEC failed to have success in West Germany in that phase.
IN DEFENSE OF THE STANDARD PICTURE: WHAT THE STANDARD PICTURE EXPLAINS THAT THE MORAL IMPACT THEORY CANNOT
Authors: Watson Bill
Published: February 2022

How do legal texts determine legal content? A standard answer to this question—sometimes called “the standard picture”—is that legal texts communicate something and what they communicate is identical to legal content. Mark Greenberg criticizes the standard picture and offers in its place his own “moral impact theory.” My goal here is to respond to Greenberg by showing how the standard picture better explains legal practice than the moral impact theory does. To that end, I first clarify certain aspects of the moral impact theory. I then critique the theory, focusing on its inability to explain (i) why practitioners reason about legal content as they do and (ii) why they agree on legal content as often as they do. Finally, I refine the standard picture and demonstrate how it explains what the moral impact theory cannot.
The Tambourine, Joseph Dale's Grand Sonata and Its Role in the Appearance of Women Musicians in the Salon
Authors: Girling Sam
Published: February 2022

By the turn of the nineteenth century composers such as Daniel Steibelt and Muzio Clementi were writing keyboard pieces with tambourine (and, occasionally, triangle) parts that were clearly intended for private salon performances by girls and young women. These works were introduced to public and private European salons during the early nineteenth century. Steibelt performed such pieces, typically waltzes, bacchanals, rondos and divertissements whilst on tour with his English wife Catherine, daughter of the London-based music publisher and patent tambourine manufacturer Joseph Dale. She became a renowned tambourine virtuoso, even attracting the attention of the Bohemian musician and writer Václav Jan Tomášek, who described the great sensation caused by Catherine's performances.

I analyse different types of works that were written for the tambourine around the year 1800. Examples of short waltzes (which were usually published in sets of 6 or 12) are plentiful – they were by far the most common pieces written for piano and tambourine – and in them the historical link between the tambourine and dance is most obvious. I argue that these waltzes may have served as a bridging point between dance-like, energetic, social activities and passive, recreational drawing-room music. Further support for this idea can be found in a Grand Sonata for pianoforte, tambourine, flute, violin and basso by Joseph Dale. The tambourine part contains numerous choreographic instructions as well as a wide variety of playing techniques such as thumb rolls, bass notes and harmonics, the likes of which did not become common practice in the orchestral or chamber repertory until the twentieth century. Dale's intention was clearly to provide an opportunity for women musicians to express themselves in ways that were contrary to contemporary expectations of female social etiquette.
Boosting exposure and response prevention with imagery-based techniques: a case study tackling sexual obsessions in an adolescent
Authors: Lau-Zhu A. , Farrington A. , Bissessar C.
Published: February 2022

Sexual obsessions are common in adolescents with obsessive compulsive disorder (OCD), but how to address these obsessions in a developmentally sensitive manner remains under-explored. This report presents the case of an adolescent who experienced unwanted sexual imagery, undergoing conventional exposure and response prevention, which was subsequently augmented with imagery-based techniques. This approach was associated with remission in symptoms of OCD and marked improvements in symptoms of anxiety and depression. The imagery-based approach was well received and valued as key to treatment success by the adolescent. This raises the tantalising possibility that working directly with images can fuel treatment innovation in tackling sexual (and non-sexual) obsessions in youth OCD.

The Abundance of Trace Elements in Human Bone Relative to Bone Type and Bone Pathology

Published: February 2022

As the global population ages and the proportion of individuals afflicted with musculoskeletal disease spirals upward, there is an increasing interest in understanding and preventing bone‐related diseases. Bone diseases, such as osteoporosis and osteoarthritis, are known to be influenced by a variety of factors including age, gender, nutrition, and genetics, but are also inherently linked to the human body's ability to produce biominerals of suitable quality. Because the crystal lattice structure and mineralogy of bone hydroxyapatite is surprisingly analogous to geological hydroxyapatite, trace element levels and exposure have long been proposed to influence the structure of biominerals as they do geological minerals (e.g., strontium substitution changes the crystal lattice of bone minerals, while toxic lead disrupt bone cellular processes leading to bone disease). Here, we explore the distribution of trace elements in human bones to evaluate the distribution of these elements with respect to bone type (cortical vs. trabecular) and bone disease (osteoarthritis vs. osteoporosis). We find higher concentrations of many metabolically active transition metals, as well as lead, in cortical bone compared to trabecular bone. When compared to patients who have osteoarthritis, and thus presumably normal bone minerals, osteoporosis patients have higher concentrations of scandium and chromium (Cr) in trabecular bone, and Cr and lead in cortical bone. Lower concentrations of barium and titanium are associated with osteoporotic trabecular bone. This survey is an exploratory cross‐sectional geochemical examination of several trace element concentrations previously understudied in human bone minerals.
