International retirement and later-life migrants in the Marche region, Italy: materialities of landscape, ‘home’, lifestyle and consumption
Authors: King Russell , Cela Eralba , Fokkema Tineke , Morettini Gabriele 
Published: October 2020

AbstractWithin the general framework of ‘lifestyle migration’, the paper explores three materialities associated with the arrival and settlement of British, German and Dutch later-life migrants in the Italian region of Marche, a relatively new ‘frontier’ region for international retirement migration. The first is about the aesthetics of landscape and the scenic and emotional qualities of the physical and social environment. The second concerns ‘home’, where we examine house types, property location and home-making practices in terms of ‘authenticity’, material objects and the cultivation of land for productive purposes. The paper's third thematic focus is on consumption patterns. Most of the 69 participants interviewed for this study hanker after what they perceive as a simpler, more genuine way of life, in tune with the surrounding mixed-farming agricultural environment and distinct from other regions where tourism has taken hold. Many grow their own produce, including some who have small vineyards and olive groves. They enjoy shopping in local markets, eating out in inexpensive local hostelries, visiting museums and cultural festivals, and exploring the many pretty villages and historic towns of the region. The participants embody later-life migration as ‘active ageing’, but those who are older and/or frailer must consider, often reluctantly, the reality of a less-active and more isolated life in the Italian countryside.
Successful balloon valvuloplasty using direct puncture of the heart for pentalogy of Cantrell with complete ectopia cordis, low birth weight, single ventricle and severe pulmonary stenosis

Published: October 2020

AbstractWe present a 31 gestational weeks’ premature baby whose fetal echocardiogram showed ectopia cordis, single ventricle and severe pulmonary stenosis. At 31 gestational weeks, an emergency caesarean section was performed, and his birth weight was 1756 g, SpO2 was 80% on 100% O2. Epicardial echocardiogram showed double inlet right ventricle, severe valvular pulmonary stenosis and no ductus arteriosus. The risk of surgery was very high, so we decided to perform balloon valvuloplasty by direct puncture of the heart. We punctured the apex of the ventricle using a 16-gauge needle under echo guidance, advanced the guidewire to the pulmonary artery and performed balloon valvuloplasty. Soon after the procedure, the cyanosis improved dramatically. This is the first report of a transcatheter procedure performed by direct puncture of the heart for ectopia cordis with complex congenital heart disease.

AbstractObjective:To evaluate the hypothesis that a perinatal educational dietary intervention focused on ‘eating for the gut microbiota’ improves diet quality of pregnant women pre- and postnatally.Design:The Healthy Parents, Healthy Kids study is a prospectively registered randomised controlled trial designed to evaluate the efficacy of a dietary intervention in altering the maternal and infant gut microbiota and improving perinatal diet quality. Eligible pregnant women were randomised to receive dietary advice from their healthcare provider or to additionally receive a three session dietary intervention. Dietary data were collected at gestation weeks 26, 31, 36 and postnatal week 4. Outcome measures were diet quality, dietary variety, prebiotic and probiotic food intakes, energy, fibre, saturated fat and discretionary food intakes. Between-group differential changes from baseline before and after birth in these dietary measures were assessed using generalised estimating equations.Setting:Melbourne, Australia.Participants:Healthy pregnant women from gestation week 26.Results:Forty-five women were randomised (twenty-two control, twenty-three intervention). Compared with the control group, the intervention group improved diet quality prior to birth (5·66 (95 % CI 1·65, 9·67), Cohen’s d: 0·82 (se 0·33)). The intervention improved dietary variety (1·05 (95 % CI 0·17, 1·94), d: 0·66 (se 0·32)) and increased intakes of prebiotic (0·8 (95 % CI 0·27, 1·33), d: 0·91 (se 0·33)) and probiotic foods (1·05 (95 % CI 0·57, 1·53), d: 1·3(se 0·35)) over the whole study period compared with the control group.Conclusion:A dietary intervention focused on ‘eating for the gut microbiota’ can improve aspects of perinatal diet quality during and after pregnancy.
WHITE RESPONSE TO BLACK DEATH
Authors: Walker Hannah , Collingwood Loren , Bunyasi Tehama Lopez 
Published: October 2020

AbstractIn the United States, Blacks overwhelmingly bear the brunt of gun violence. While Blacks are more likely to favor gun restrictions than are Whites, the influence of Black gun death on Whites’ attitudes about gun control has not been investigated. We advance a theory to explain White response to Black firearm fatalities: Black gun death is explicitly and implicitly racialized in the public discourse and imagination. The roots of the gun control debate are themselves likewise racialized, and portrayals of Black gun death has the potential to tap latent racial biases among Whites. As a consequence, exposure to routinized Black gun death either fails to move White opinion, or moves Whites to greater support for gun rights. The influence of race on White public opinion is particularly concerning in an era when health officials consider gun death a public health crisis. First, we evaluate this theory with a regression discontinuity (RDD) analysis of the effects of a highly salient gun death of a young Black boy in Chicago on Whites’ opinions about gun control. Relative to White people interviewed before the death, White people interviewed after the death record greater opposition to gun control. Second, we fielded a survey experiment, exposing respondents to the reported gun homicide of either Black or White thirteen-year-old boys. Relative to a control, respondents in the Black death condition are unmoved, whereas respondents in the White death condition report greater levels of support for gun control. Implications are discussed.
Intrinsic absorption profile and radiative cooling rate of a PAH cation revealed by action spectroscopy in the cryogenic electrostatic storage ring DESIREE

Published: October 2020

AbstractThe multi-photon photodissociation (MPD) action spectrum of the coronene cation $$({{\rm{C}}_{24}}{\rm{H}}_{12}^ + )$$ has been measured as a function of storage time up to 60 s in the cryogenic electrostatic storage ring DESIREE. These measurements reveal not only the intrinsic absorption profile of isolated coronene cations, but also the rate at which hot-band absorptions are quenched by radiative cooling. The cooling rate is interpreted using a Simple Harmonic Cascade model of infrared vibrational emission.
PAH clusters as interstellar very small grains
Authors: Roser Joseph. E. , Ricca Alessandra 
Published: October 2020

AbstractPAH clusters are one candidate species for the interstellar “very small grains” or “VSGs”, i.e., dust grains small enough to be stochastically heated and contribute to the aromatic infrared emission bands (AIBs). This possibility motivated laboratory experiments on the infrared spectroscopy of PAH clusters using matrix isolation spectroscopy. The spectral shifts due to PAH clustering in argon matrices provide clues for the AIB contribution from PAH clusters in the interstellar medium. Here we review results from a number of small PAH species, extrapolation to the much larger PAHs believed to be present in the interstellar medium, and the implications for a PAH cluster contribution to the VSG population.

Characterization of large carbonaceous molecules in cosmic dust analogues and meteorites
Authors: Sabbah Hassan , Carlos Mickaël , Joblin Christine 
Published: October 2020

AbstractWe present a new experimental setup called AROMA (The Aromatic Research of Organics with Molecular Analyzer) based on the use of laser mass spectrometry techniques. We demonstrate the potential of AROMA for the analysis of meteoritic samples and cosmic dust analogues. Tens of peaks are identified in the mass spectra with notable discrepancies across the different samples. These discrepancies provide clues on the chemical history of each sample and are not a bias of our analysis. A double bound-equivalent (DBE) method is applied to sort the detected carbonaceous molecules into families of compounds. It reveals in addition of polycyclic aromatic hydrocarbons, the presence of other populations such as mixed aromatic-aliphatic species and carbon clusters.
Using cold plasma to investigate the mechanisms involved in cosmic dust formation: Role of the C/O ratio and metals

Published: October 2020

AbstractUsing a cold plasma reactor in which we inject an organosilicon molecular precursor, we investigate chemical mechanisms that can be involved in dust formation in evolved stars. By injecting metal atoms into the gas-phase, we investigate the role of metals on dust composition. We show the formation of composite particles made of pure metal (silver) nanoparticles embedded in an organosilicon dust. We study the impact of oxygen and show that it can inhibit dust formation, likely through the destruction of nucleation seeds.
Laboratory astrophysics: Key to understanding the Universe
Authors: van Dishoeck Ewine F. 
Published: October 2020

AbstractThis brief overview stresses the importance of laboratory data and theory in analyzing astronomical observations and understanding the physical and chemical processes that drive the astrophysical phenomena in our Universe. This includes basic atomic and molecular data such as spectroscopy and collisional rate coefficients, but also an improved understanding of nuclear, plasma and particle physics, as well as reactions and photoprocesses in the gaseous and solid state that lead to chemical complexity and building blocks for life. Systematic laboratory collision experiments have provided detailed insight into the steps that produce pebbles, bricks and ultimately planetesimals starting from sub-μ-sized grains. Sample return missions and meteoritic studies benefit from increasingly sophisticated laboratory machines to analyze materials and provide compositional images on nanometer scales. Prioritization of future data requirements will be needed to cope with the increasing data streams from a diverse range of future astronomical facilities within a constrained laboratory astrophysics budget.
H2 formation on Mg-rich amorphous silicates
Authors: Mennella Vito , Suhasaria Tushar 
Published: October 2020

AbstractWe present the results of an experimental study on the interaction of D atoms with Mg-rich amorphous silicates. The effects of D irradiation have been analyzed by infrared spectroscopy. The results indicate that HD forms by abstraction of hydrogen atoms chemisorbed in the hydroxyl groups of silicate grains. The formation process occurs for grain and atom temperatures relevant to photodissociation regions.

Published: October 2020

AbstractHD 66051 is an eclipsing and spectroscopic double-lined binary (SB2), hosting two chemically peculiar stars: a highly peculiar B star as primary and an Am star as secondary. The investigation of the new high-resolution UVES spectrum of HD 66051 allowed us to decide on the chemical peculiarity type of both components with more reliability. An analysis of TESS photometric time series data will further specify the physical parameters of the stars and the orbital parameters of the system.
From molecules to dust grains: The role of alumina cluster seeds

Published: October 2020

AbstractAsymptotic Giant Branch (AGB) stars contribute a major part to the global dust budget in galaxies. Owing to their refractory nature alumina (stoichiometric formula AlO) is a promising candidate to be the first condensate emerging in the atmospheres of oxygen-rich AGB stars. Strong evidence for that is supplied by the presence of alumina in pristine meteorites and a broad spectral feature observed around ∼ 13 μm. The emergence of a specific condensate depends on the thermal stability of the solid, the gas density and its composition. The evaluation of the condensates is based on macroscopic bulk properties. The growth and size distribution of dust grains is commonly described by Classical Nucleation Theory (CNT). We question the applicability of CNT in an expanding circumstellar envelope as CNT presumes thermodynamic equilibrium and requires, in practise, seed nuclei on which material can condense. However, nano-sized molecular clusters differ significantly from bulk analogues. Quantum effects of the clusters lead to non-crystalline structures, whose characteristics (energy, geometry) differ substantially, compared to the bulk material. Hence, a kinetic quantum-chemical treatment involving various transition states describes dust nucleation most accurately. However, such a treatment is prohibitive for systems with more than 10 atoms. We discuss the viability of chemical-kinetic routes towards the formation of the monomer (Al2O3) and the dimer (Al4O6) of alumina.
Thermal desorption of formamide and methylamine from graphite and amorphous water ice surfaces
Authors: Chaabouni Henda , Diana Stephan , Nguyen Thanh 
Published: October 2020

AbstractThermal desorption experiments of Formamide (NH2CHO) and methylamine (CH3NH2) were performed in LERMA-Cergy laboratory to determine the values of the desorption energies of formamide and methylamine from analogues of interstellar dust grain surfaces, and to understand their interaction with water ice. We found that more than 95 % of solid NH2CHO diffuses through the np-ASW ice surface towards the graphitic substrate, and is released into the gas phase with a desorption energy distribution Edes = (7460 – 9380) K, measured with the best-fit pre-exponential factor A=1018 s-1. Whereas, the desorption energy distribution of methylamine from the np-ASW ice surface (Edes =3850-8420 K) is measured with the best-fit pre-exponential factor A=1012s-1. A fraction of solid methylamine, of about 0.15 monolayer diffuses through the water ice surface towards the HOPG substrate, and desorbs later, with higher binding energies (5050-8420 K), which exceed that of the crystalline water ice (Edes =4930 K), calculated with the same pre-exponential factor A=1012 s-1.

AbstractThe emergence of life on Earth may have its origin in organic molecules formed in the interstellar medium. Molecules with amide and isocyanate groups resemble structures found in peptides and nucleobases and are necessary for their formation. Their formation is expected to take place in the solid state, on icy dust grains, and is studied here by far-UV irradiating a CH4:HNCO mixture at 20 K in the laboratory. Reaction products are detected by means of infrared spectroscopy and temperature programmed desorption - mass spectrometry. Various simple amides and isocyanates are formed, showing the importance of ice chemistry for their interstellar formation. Constrained by experimental conditions, a reaction network is derived, showing possible formation pathways of these species under interstellar conditions.
Sensitivity to salinity at the emergence and seedling stages of barnyardgrass (Echinochloa crus-galli), weedy rice (Oryza sativa), and rice with different tolerances to ALS-inhibiting herbicides
Authors: Fogliatto Silvia , Patrucco Lorenzo , Milan Marco , Vidotto Francesco 
Published: October 2020

AbstractSalinization is affecting many rice (Oryza sativa L.) areas worldwide and weed infestation, together with the occurrence of herbicide-resistant populations, is further limiting rice yield. This study aimed at evaluating the effect of water salinity on the emergence and seedling growth of five Italian barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] populations (three sensitive and two resistant to acetolactate synthase–inhibiting herbicides), three Italian weedy rice (Oryza sativa L.) populations (all sensitive to imazamox), and two rice varieties (the conventional ‘Baldo’ variety and the imazamox-tolerant ‘CL80’ one). In 2017, seeds were sown in alveolar trays filled with sand, a nutrient solution, and water with the following salt concentrations: 0, 50, 100, 150, 200, and 250 mM NaCl. Plant emergence (after 15 d), plant height, shoot and root weight, chlorophyll a, chlorophyll b, and carotenoid content were measured at 40 d after sowing. Echinochloa crus-galli showed a higher tolerance to salinity than O. sativa and rice. All species were affected more at the seedling stage than at emergence. A variable behavior of the herbicide-resistant populations was shown; one resistant E. crus-galli population was affected more by salinity and showed a lower emergence rate (about 20% against 40% emergence of the other populations at the highest salt concentration) and reduced seedling growth, while the other resistant population’s response was similar to that of the sensitive populations. The chlorophyll content increased as the salt content increased in all E. crus-galli populations. The highest emergence and growth reduction in O. sativa were recorded in the imazamox-tolerant rice. Rice and O. sativa were able to grow only up to 50 mM. Echinochloa crus-galli populations are probably favored under saline conditions, while lower infestation by O. sativa can be expected.
Allow Peace to Reign: Musical Genres ofFújìandIslamicAllegorise Nigerian Unity in the Era of Boko Haram

Published: October 2020

AbstractA proliferation of popular music genres flourished in post-independence Nigeria: highlife,jùjú, Afrobeat, andfújì.Originating within Yorùbá Muslim communities, the genres offújìand Islamic are Islamised dance music genres characterised by their Arabic-influenced vocal style, Yorùbá praise poetry, driving percussion, and aesthetics of incorporation, flexibility, and cultural fusion. Based on analysis of interviews and performances in Ìlọrin in the 2010s, this article argues that the genres offújìand Islamic allegorise Nigerian unity—an ideology of tolerance, peaceful coexistence, and equity—while exposing the gap between the aspiration for unity and everyday inequities shaped by gender and morality.
Better Battles by a Self-Compassionate Partner?
Authors: Tandler Nancy , Krüger Martin , Petersen Lars-Eric 
Published: October 2020

Abstract. Self-compassion entails being kind towards oneself when encountering uncontrollable life events, inadequacies, or failure. When in conflict with a romantic partner, we expected self-compassion to be associated positively with functional (positive problem solving) and negatively with dysfunctional styles (conflict engagement, withdrawal, compliance). Adult individuals ( n = 163) involved in a serious romantic relationship for at least 2 years responded to a questionnaire that assessed self-compassion, personality factors, conflict resolution styles, and relationship satisfaction. High self-compassionate partners reported more functional and less dysfunctional styles when statistically controlling for demographics, neuroticism, and agreeableness. Conflict resolution styles fully mediated the significant path between self-compassion and relationship satisfaction.
Peer Perceptions of Communal Narcissism and Communalism in At-Risk Adolescents
Authors: Barry Christopher T. , Sidoti Chloe L. , Wong Megan 
Published: October 2020

Abstract. The present study extended research on the relation of communal narcissism in adolescents with self- and peer-reported personality and behavior. Although communal narcissism may be associated with negative peer perceptions, a communal orientation that does not also convey superiority (i.e., communalism) may be viewed more favorably. Self- and peer-perceptions were investigated as a function of communal narcissism and a non-narcissistic communal orientation (i.e., by altering the Communal Narcissism Inventory to reflect more humble self-views). Participants were 246 adolescents, ages 16–19 years, who were attending a quasi-military residential program for youth who have dropped out, or were at-risk of dropping out, of school. Communal narcissism and communalism were significantly interrelated. Communal narcissism was negatively associated with unique variance in self-reported empathy, whereas communalism was positively associated with self-reported empathy and more strongly related to peer-reported prosociality. The role of superiority in communal domains in adolescent self-perception and peer relationships is discussed.
Selflessness and Happiness in Everyday Life
Authors: Pellerin Nicolas , Raufaste Eric , Dambrun Michael 
Published: October 2020

Abstract. Using the experience sampling method (ESM), this study examines the relationship between experienced selflessness and experienced happiness. Based on the self-centered/selflessness happiness model (SSHM), we hypothesized that: (a) these two constructs would be positively related and (b) harmony feeling would mediate this relation. Using ESM, the participants ( N = 63) filled in a short survey, five times a day during 2 days (response rate = 79.2%; 482 observations). A linear mixed-model analysis showed that selflessness and harmony feelings were significant predictors of happiness. Finally, a mediation analysis indicated that harmony feeling emerged as a significant mediator of the relationship between selflessness and happiness at the experienced level. Overall, the study supports the idea that happiness does not depend solely on the satisfaction of one’s expectations but experiencing the self as an interdependent and relational entity also plays an important role. The implications of this study are discussed.
