Currency Unions and Global Value Chains: The Impact of the Euro on the Italian Value Added Exports
Authors: Cerulli Giovanni , Nenci Silvia , Salvatici Luca , Zinilli Antonio 
Published: June 2021

AbstractMany estimates of the effect of the common currency on trade have been made, although a clear answer has yet to be given. This work analyses the trade effect of the euro by providing a twofold contribution. First, one of the main stylised facts that has emerged from the recent literature is that trade flows in gross terms can differ substantially from those measured in value added terms. Accordingly, we focus on the structure of global value chains rather than conventional gross trade. To this aim, we provide an estimate of the value added trade flows that would have existed between Italy and its main trading partners if Italy had not joined the monetary union and show how, and to what extent, international production sharing has been affected. Second, we use a methodology that is different from traditional, parametric ones. Specifically, we apply the synthetic control method to construct appropriate counterfactuals and estimate the causal impact of the euro. Our empirical analysis provides a relevant case for considering value added in addition to gross trade since it shows that the euro facilitated the forward integration of Italian exports, whereas it slowed down backward integration. Overall, these results suggest that the euro had an impact on Italian global value chain participation by altering value added flows across member as well as non-member states, with great heterogeneity in the results across value added trade components and sectors.
Space weather: the solar perspective
Authors: Temmer Manuela 
Published: June 2021

AbstractThe Sun, as an active star, is the driver of energetic phenomena that structure interplanetary space and affect planetary atmospheres. The effects of Space Weather on Earth and the solar system is of increasing importance as human spaceflight is preparing for lunar and Mars missions. This review is focusing on the solar perspective of the Space Weather relevant phenomena, coronal mass ejections (CMEs), flares, solar energetic particles (SEPs), and solar wind stream interaction regions (SIR). With the advent of the STEREO mission (launched in 2006), literally, new perspectives were provided that enabled for the first time to study coronal structures and the evolution of activity phenomena in three dimensions. New imaging capabilities, covering the entire Sun-Earth distance range, allowed to seamlessly connect CMEs and their interplanetary counterparts measured in-situ (so called ICMEs). This vastly increased our knowledge and understanding of the dynamics of interplanetary space due to solar activity and fostered the development of Space Weather forecasting models. Moreover, we are facing challenging times gathering new data from two extraordinary missions, NASA’s Parker Solar Probe (launched in 2018) and ESA’s Solar Orbiter (launched in 2020), that will in the near future provide more detailed insight into the solar wind evolution and image CMEs from view points never approached before. The current review builds upon the Living Reviews article by Schwenn from 2006, updating on the Space Weather relevant CME-flare-SEP phenomena from the solar perspective, as observed from multiple viewpoints and their concomitant solar surface signatures.

AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinetic and neuromuscular) and physiological methodology (at the systemic and/or muscle level), providing recommendations for standardization/control of the experimental setup. We describe the types of measuring equipment and technology that are most suitable in this context. Moreover, we also deal with certain aspects of nomenclature of the classical and skating sub-techniques. In addition to enhancing the quality of studies on XC skiing, Nordic combined and biathlon, our guidelines should also be of value for sport scientists and coaches in other disciplines where physiological and/or biomechanical measurements are performed in the laboratory and/or outdoors.

Published: June 2021

AbstractSmoking cessation method effectiveness is discussed among socially disadvantaged smokers. Our aim was to measure real-life effectiveness of the choice of a multi-component group intervention in comparison with individual usual care. We report an observational study (N = 100). Disadvantaged smokers were screened with a validated tool. We designed a multi-component structured behavioural group intervention, delivered in weekly group sessions during 6 weeks. Usual care consisted of individual visits. Both groups received free nicotine replacement therapy. We observed 33 smokers participating in the group intervention, while 67 received usual care. Abstinence at 6 weeks was 24.2% (n = 8) in the group intervention versus 11.9% (n = 8) in usual care (p = .115). Also, 36.4% (n = 12) of group intervention patients had reduced their cigarette consumption versus 16.4% (n = 11) in usual care (p = .026). In addition, 6.1% (n = 2) dropped out of group versus 31.3% (n = 21) in usual care (p = .005). Finally, 6 months after their first visit, 15.2% (n = 5) of group intervention patients and 4.5% (n = 3) in usual care were abstinent (p = .111). Group intervention choice versus usual care might facilitate smoking abstinence, reduction, and follow-up adherence.
Wage and employment effects of immigration: Evidence from South Korea
Authors: Kim Hyejin 
Published: June 2021

AbstractThis paper studies the impact of immigration on native labor market outcomes in South Korea. We exploit the variation in immigration flows in an education-experience cell and find that, on average, immigration has no harmful effect on the wages or employment of native workers. However, there is a great heterogeneity of wage effects across education groups: high school dropouts suffer from the adverse effects, whereas the effects for college graduates are positive. We find the potential explanation for these differential effects in the suggestive evidence on the degree of substitution. Specifically, we examine the similarity of occupational distribution between natives and immigrants and assimilation patterns for immigrants.
Affirmative Action in Medical School: A Comparative Exploration
Authors: Sander Richard 
Published: June 2021

AbstractA significant body of evidence shows that law schools and many elite colleges use large admissions preferences based on race, and other evidence strongly suggests that large preferences can undermine student achievement in law school and undergraduate science majors, thus producing highly counterproductive effects. This article draws on available evidence to examine the use of racial preferences in medical school admissions, and finds strong reasons for concern about the effects and effectiveness of current affirmative action efforts. The author calls for better data and careful investigation of several identified patterns.
Creating the Truth with Persons Living with Advanced Dementia
Authors: Karlawish Jason 
Published: June 2021

AbstractTruth telling to persons living with dementia is a nuanced problem that demands negotiating between the hazards of principlism and the loving deceiver’s demand to lie as needed. To ban deception, as we do restraints, would be misguided and cruel. So too to demand we always tell the truth. We ought to adopt a practice called “creative care.” It begins with the premise that person’s living with dementia are capable of creativity. Creative care breaks down the mysterious fourth wall we build around persons living with dementia, especially persons with advanced dementia. It invites us to see a person living with dementia as a person who is capable of creating something beautiful. They need our time and words, not our lies and sedatives.
NEW MARINE RESERVOIR CORRECTION VALUES (ΔR) APPLICABLE TO DATES ON NEOLITHIC SHELLS FROM THE SOUTH COAST OF KOREA
Authors: Kim Habeom , Lee Hyunsoo , Lee Gyoung-Ah 
Published: June 2021

ABSTRACTShells from Neolithic shell midden sites have been routinely dated in Korea, but they have not been calibrated based on the correction values (ΔR) for the marine reservoir effect (MRE). A lack of proper calibration has left dates on shells incomparable to those on terrestrial samples, and thus unusable in building the chronological sequence of shell middens. Here, we report the two new ΔR values of a pre-bomb (pre-1950) blue mussel from the south coast. We applied the two new and the two previously reported ΔR values to the three dates on marine shells from the Bibongri shell midden in southeastern Korea. Our ΔR adjusted calibration and the comparison to dates on charcoal and bone remains clarify an ambiguity in the stratigraphy and the Early Neolithic chronology at Bibongri. Our contribution is to provide the ΔR values that can be further applied to other Neolithic shell middens along the south coast.

AbstractPolycystic ovary syndrome (PCOS) is associated with a higher prevalence of sleep disturbances and obesity. Treatment of PCOS includes modifying lifestyle behaviours associated with weight management. However, poor sleep in the non-PCOS population has been associated with poorer lifestyle behaviours. The aim was to investigate whether sleep disturbance confounds or modifies the association between lifestyle factors and PCOS. This was a cross-sectional analysis from the Australian Longitudinal Study on Women’s Health cohort aged 31–36 years in 2009 were analysed (n 6067, 464 PCOS, 5603 non-PCOS). Self-reported data were collected on PCOS, anthropometry, validated modified version of the Active Australia Physical Activity survey, validated FFQ and sleep disturbances through latent class analysis. Women with PCOS had greater adverse sleep symptoms including severe tiredness (P = 0·001), difficulty sleeping (P < 0·001) and restless sleep (P < 0·001), compared with women without PCOS. Women with PCOS also had higher energy consumption (6911 (sd 2453) v. 6654 (sd 2215) kJ, P = 0·017), fibre intake (19·8 (sd 7·8) v. 18·9 (sd 6·9) g, P = 0·012) and diet quality (dietary guidelines index (DGI)) (88·1 (sd 11·6) v. 86·7 (sd 11·1), P = 0·008), lower glycaemic index (50·2 (sd 4·0) v. 50·7 (sd 3·9), P = 0·021) and increased sedentary behaviour (6·3 (sd 2·8) v. 5·9 (sd 2·8) h, P = 0·009). There was a significant interaction between PCOS and sleep disturbances for DGI (P = 0·035), therefore only for women who had adequate sleep was PCOS associated with a higher DGI. For women with poorer sleep, there was no association between PCOS and DGI. The association between PCOS and improved diet quality may only be maintained if women can obtain enough good quality sleep.
Alcohol and early mortality (before 65 years) in the ‘Seguimiento Universidad de Navarra’ (SUN) cohort: does any level reduce mortality?

Published: June 2021

AbstractThe aim of this study was to assess the association between alcohol intake and premature mortality (younger than 65 years) and to explore the effect of potential alcohol underreporting by heavy drinkers. We followed-up 20 272 university graduates. Four categories of alcohol intake were considered (abstainer, light, moderate and heavy consumption). Repeated measurements of alcohol intake and updated information on confounders were used in time-dependent Cox models. Potential underreporting of alcohol intake by some heavy drinkers (likely misclassified as light or moderate drinkers) was explicitly addressed in an attempt to correct potential underreporting by using indirect information. During 12·3 years of median follow-up (interquartile range: 6·8–15·0), 226 participants died before their 65th birthday. A higher risk of early mortality was found for the highest category of alcohol intake (≥50 g/d) in comparison with abstention (multivariable-adjusted hazard ratio (HR) = 2·82, 95 % CI 1·38, 5·79). In analyses of alcohol as a continuous variable, the multivariable-adjusted HR was 1·17 (95 % CI 1·08, 1·26), for each 10 g/d of alcohol. This harmful linear association was present both in uncorrected models and in models corrected for potential underreporting. No significant inverse association between light or moderate alcohol intake and premature mortality was observed, even after correcting for potential misclassification. Alcohol intake exhibited a harmful linear dose–response association with premature mortality (<65 years) in this young and highly educated Mediterranean cohort. Our attempts to correct for potential misclassification did not substantially change these results.
Hegemonic Muslim Masculinities and Their Others: Perspectives from South and Southeast Asia
Authors: Peletz Michael G. 
Published: June 2021

AbstractThis article provides ethnographic, comparative, and theoretical perspectives on Muslim masculinities in South and Southeast Asia, home to more than half the world's 1.9 billion Muslims. Its empirical and thematic focus broadens the scholarly discussion of gender and sexuality among Muslims insofar as most of the literature deals with the Middle East and North Africa and is devoted to women and the discourses and practices of femininity and sexuality associated with them. More specifically, the article develops theoretical insights bearing on gender hegemonies and the pluralities and hierarchies of discourses on masculinities in the Muslim-majority nations of Pakistan and Malaysia, each of which illustrates broad trends in the region. It thus sheds important light on the empirical diversity of Muslim masculinities (amidst commonalities) and some of the ways they have been informed by locally and regionally variable macro-level processes keyed to colonialism, postcolonial nation-building, global/neoliberal capitalism, and post-Cold War geopolitical struggles including the Global War on Terror.
A NOTE ON RANK TWO STABLE BUNDLES OVER SURFACES
Authors: REYES-AHUMADA GRACIELA , ROA-LEGUIZAMÓN L. , TORRES-LÓPEZ H. 
Published: June 2021

Abstract.Let π : X → C be a fibration with integral fibers over a curve C and consider a polarization H on the surface X. Let E be a stable vector bundle of rank 2 on C. We prove that the pullback π*(E) is a H-stable bundle over X. This result allows us to relate the corresponding moduli spaces of stable bundles $${{\mathcal M}_C}(2,d)$$ and $${{\mathcal M}_{X,H}}(2,df,0)$$ through an injective morphism. We study the induced morphism at the level of Brill–Noether loci to construct examples of Brill–Noether loci on fibered surfaces. Results concerning the emptiness of Brill–Noether loci follow as a consequence of a generalization of Clifford’s Theorem for rank two bundles on surfaces.

AbstractWhole-plant soybean silage (WPSS) is a potential high-protein roughage source for ruminant diets. However, WPSS can be difficult to ensile and fermentation is a challenge. This study was conducted to evaluate the effect of chitosan and microbial inoculants on fermentation profile, fermentation losses, chemical composition, and in vitro degradation of WPSS. Forty experimental silos (PVC tubing with 28 cm i.d. and 25 cm height) were produced. Soybean plants from 10 plots were ensiled in a completely randomized block design to evaluate the following treatments: (1) control (CON): WPSS without additives; (2) chitosan (CHI): WPSS additive with 6 g/kg DM of chitosan; (3) LBB: WPSS treated with 5.0 × 107 colony-forming units (CFU) of Lactobacillus buchneri (NCIM 40788) per kg of fresh matter and (4) LPP: WPSS treated with 1.6 × 108 CFU of Lactobacillus plantarum and 1.6 × 108 CFU of Pediococcus acidilactici per kg of fresh matter. Silos were opened 120 days after ensiling. Microbial inoculants reduced silage pH, whereas LPP-treated silos showed the lowest concentration of NH3-N, ethanol, butyric, acetic, branched-chain, and propionic organic acids. LBB-treatment decreased lactic acid bacteria (LAB) count relative to other treatments, and LPP-treatment showed the lowest fermentation losses, improving dry matter (DM) recovery. Relative to other treatments, LPP increased silage DM, organic matter, and decreased acid detergent insoluble crude protein (CP), improving DM and neutral detergent fibre in vitro degradation. Treatments showed no effect on silage aerobic stability. Thus, LPP-treatment improves fermentation profile, reduces fermentation losses, and increases the nutritional value of WPSS.
Mid upper arm circumference as an alternative measure to assess the nutritional status of adolescents: a study in India based on NFHS-4 data
Authors: Roy Aparna , Sekher T. V. 
Published: June 2021

AbstractUse of body mass index (BMI) to assess the nutritional status of adolescents requires many resources, especially for country-level assessment. This study aimed to determine the relationship between BMI and mid upper arm circumference (MUAC) among adolescent males and females in India and to examine whether MUAC effectively represents the nutritional status of adolescents. The study utilized anthropometric measurement data collected by India’s National Family Health Survey-4 (2015–16). The weighted sample for analysis included 91,315 female and 14,893 male adolescents. The BMI and MUAC measurements showed a positive correlation in both female and male adolescents. Using BMI-for-ageZ-score classifications, 12.7% of the adolescents were undernourished. Using MUAC (in cm) as per NACS (Nutrition Assessment, Counselling, and Support) guidelines and Mrambaet al.(2017) classified 22.9% and 3.7% of the adolescents as undernourished respectively. Finally, using the MUAC-for-ageZ-score classification, 98.4% of adolescents were determined to be normal and 1.7% undernourished. Sensitivity and specificity tests of the MUAC cut-offs, in comparison with BMI cut-offs, showed that all three MUAC cut-off classifications had high specificity (NACS cut-off: 81.3%; Mrambaet al.cut-off (cm): 97.7%; Mrambaet al.cut-off (Z-score): 99.1%). The NACS cut-off had moderately high sensitivity (52.2%) but the Mrambaet al.cut-offs had low sensitivity (13.3% for the centimetre cut-off and 6.6% for theZ-score cut-off). Sensitivity and specificity tests proved the relationship between BMI and MUAC, and that MUAC represents adolescent nutritional status with considerable efficiency. With further research, it may be established that MUAC is a better and promising measure of adolescent nutrition, having the advantage of needing fewer resources for data collection. The MUAC has the potential to offer a simple and low-resource alternative to BMI to assess nutritional status among adolescents in poor countries.
Self-limited myocarditis presenting with chest pain and ST segment elevation in adolescents after vaccination with the BNT162b2 mRNA vaccine

Published: June 2021

AbstractTwo adolescent males presented within 3 days after the first and second dose of the BNT162b2 vaccine with chest pain. Elevated troponin levels, ST segment elevation, and enhancement of the myocardium in cardiac MRI suggested myocarditis. Left ventricular function remained normal, symptoms resolved, and patients were discharged in 4 days. BNT162b2 vaccine may be associated with self-limited myocarditis in youth.
How Do You Solve a Problem Like Maria?US – Countervailing Measures (China) (21.5)
Authors: Nelson Douglas 
Published: June 2021

AbstractThe rise of China as a genuine world power, economically and militarily, constitutes the gravest challenge faced by the liberal international order constructed in the aftermath of the Great Depression and the Second World War. A major source of strain in the trade relations between China and the other core members of the liberal world trading system is its extensive use of state-owned enterprises as an instrument of general (domestic) economic policy. This paper builds on Ruggie's theory of embedded liberalism and the theory of economic policy to characterize the political and economic difficulties and opportunities in moving toward a new regime for dealing with subsidies. The conclusion sketches some goals such a regime should seek to embody.
