Tracing international migration in projections of income and inequality across the Shared Socioeconomic Pathways
Authors: Benveniste Hélène , Cuaresma Jesús Crespo , Gidden Matthew , Muttarak Raya 
Published: June 2021

AbstractThe Shared Socioeconomic Pathways (SSPs) represent five narratives of future development used for climate change research. They include quantified projections of socioeconomic variables such as population, income levels, inequalities, and emissions over the twenty-first century. The SSP’s population projections embody explicit, pathway-specific international migration assumptions, which are only implicit in the projections of other variables. In this contribution, we explicitly quantify the effects of international migration on income levels and income inequality across and within countries by comparing the original SSP projections to scenarios of zero migration. Income projections without migration are obtained by removing two effects of migration on income dynamics: changes in population size and remittances sent to origin countries. We base our remittance estimates on migrant stocks derived from bilateral migration flow estimates obtained from a gravity model. We find that, on average, migration tends to make the world richer in all SSP narratives. The nature of migration and remittance corridors is shaped by the specific scenario of future development considered. Depending on the particular SSP narrative and world region considered, the effects of migration on income can be substantial, ranging from −5 to +21% at the continental level. We show that migration tends to decrease income inequality across countries and within country in most destination countries but does not affect within-country inequality in origin countries. This new set of projections is consistent with the interdisciplinary framework of the SSPs, which makes it particularly useful for assessing global climate and sustainable development policy options.
Motherhood: Female Perspectives and Experiences of Being a Parent with ASC
Authors: Winnard Rebecca , Roy Mark , Butler-Coyne Hannah 
Published: June 2021

AbstractLittle is known about the emotional pressures and practical management of daily challenges and, intra and interpersonal demands of raising a child as a parent with a diagnosis of Autistic Spectrum Conditions. The present study utilised a qualitative approach to understand perceptions of females diagnosed on the autistic spectrum of ‘being a parent’. Eight semi-structured interviews were analysed using Interpretative Phenomenological Analysis. Benefits and challenges of being a parent were highlighted alongside population-specific skill and characteristics associated with strength and resilience, love, nurture, routine and sensory considerations. Findings identify the need for population-specific specialist parenting support, provide direction for professionals in clinical settings and expand the paucity of research in this area.

Published: June 2021

AbstractThe introduction of emtricitabine/tenofovir diphosphate (FTC/TDF) as pre-exposure prophylaxis (PrEP) for HIV prevention has raised questions regarding which clinicians will serve as prescribers and how providers will be educated about this HIV prevention strategy. We piloted an HIV Prevention Education Program called PrEP University (PrEP U) to address knowledge gaps in HIV prevention among medical trainees. We examined PrEP awareness and assessed learning as a result of the program, measuring knowledge before and after the lectures with an anonymous 5-question multiple choice test. A total of 198 learners participated in PrEP University, which included 127 first year medical students, and post-graduate trainees in internal medicine (n = 23), family medicine (n = 16), OBGYN (n = 13) and pharmacy (n = 19). Prior to PrEP U, 27% of all participants were not aware of PrEP and an additional 8% were unsure if they had heard of it. Knowledge increased significantly after the education program among trainees in OBGYN (2.3 vs 3.8, p < 0.001), pharmacy (1.4 vs 2.5, p = 0.012) and school of medicine (3.3 vs 4.4, p < 0.001), with a trend seen in family medicine (2.7 vs. 3.7, p = 0.067) and internal medicine (2.7 vs 3.4, p = 0.068). Overall, an HIV Prevention Education Program was successfully administered to nearly 200 participants and resulted in improved knowledge of HIV prevention and PrEP across. Pharmacists and OBGYN physicians are two groups with an expanding role in the use of PrEP. Similar programs at other medical schools should be implemented to ensure that future physicians and pharmacists are comfortable with PrEP prescription.

AbstractAgroforestry (AF)-based adaptation to global climate change can consist of (1) reversal of negative trends in diverse tree cover as generic portfolio risk management strategy; (2) targeted, strategic, shift in resource capture (e.g. light, water) to adjust to changing conditions (e.g. lower or more variable rainfall, higher temperatures); (3) vegetation-based influences on rainfall patterns; or (4) adaptive, tactical, management of tree-crop interactions based on weather forecasts for the (next) growing season. Forty years ago, a tree physiological research tradition in aboveground and belowground resource capture was established with questions and methods on climate-tree-soil-crop interactions in space and time that are still relevant for today’s challenges. After summarising early research contributions, we review recent literature to assess current levels of uncertainty in climate adaptation assessments in and through AF. Quantification of microclimate within and around tree canopies showed a gap between standard climate station data (designed to avoid tree influences) and the actual climate in which crop and tree meristems or livestock operates in real-world AF. Where global scenario modelling of ‘macroclimate’ change in mean annual rainfall and temperature extrapolates from climate station conditions in past decades, it ignores microclimate effects of trees. There still is a shortage of long-term phenology records to analyse tree biological responses across a wide range of species to climate variability, especially where flowering and pollination matter. Physiological understanding can complement farmer knowledge and help guide policy decisions that allow AF solutions to emerge and tree germplasm to be adjusted for the growing conditions expected over the lifetime of a tree.
How achievement motive enactment shapes daily flow experience and work engagement: The interplay of personality systems
Authors: Digutsch Jan , Diestel Stefan 
Published: June 2021

AbstractIn the present study, we examined how different forms of achievement motive interact to predict daily flow experience and work engagement. In particular, we conducted two diary studies to examine the main and interaction effects of motive enactment via extension memory (a macrosystem that enables holistic and experience-based information processing) and via the object recognition system (an alert-oriented macrosystem). In study 1, in line with personality systems interaction (PSI) theory, we found that motive enactment via extension memory fosters both day-specific flow and work engagement, whereas the conjunction of both forms of motive enactment has beneficial effects on flow and work engagement (two-way interaction). In study 2, we found that role clarity moderates the interaction of the two forms of enactment, indicating that the two-way interaction occurs when role clarity is low. Our results imply that the interplay of different dispositional forms of achievement motive enactment shapes how employees experience flow and engagement.
The Calculus of Natural Calculation
Authors: Gazzari René 
Published: June 2021

AbstractThe calculus of Natural Calculation is introduced as an extension of Natural Deduction by proper term rules. Such term rules provide the capacity of dealing directly with terms in the calculus instead of the usual reasoning based on equations, and therefore the capacity of a natural representation of informal mathematical calculations. Basic proof theoretic results are communicated, in particular completeness and soundness of the calculus; normalisation is briefly investigated. The philosophical impact on a proof theoretic account of the notion of meaning is considered.
Trees as a solar control measure for southern-oriented street frontages. Analysis of a selected street model for a humid continental climate
Authors: Zielonko-Jung Katarzyna , Janiak Justyna 
Published: June 2021

AbstractThe present study is aimed at the analysis of possibilities for shading southern frontage of street oriented along the E-W axis by the single row of trees, parallel to the southern elevations. The effectiveness of solar control shading was tested depending on the geometric relationships between trees and buildings. Numerical simulation analyses were conducted in Rhinoceros® program for the street located in humid continental climate in city Płock, Poland (52°32′50 “N 19°42’00 “E), for the day of the highest degree of total solar radiation in the year i.e. June 7th, during hours: 8.00a.m - 5.00 p.m. The analysis has proved that a row of 20–25 year old Sycamore Maple ‘Rotterdam’ in the street 30 m wide and 18 m high (H/W = 0.6), can provide solar protection for the southern frontage, especially when trees are located no more than 4 m away. Location of greenery within the range of 4 to 5 m from the buildings leads to a radical reduction in the possibility of shading the wall surfaces (at 5 m to 0%). Over 90% of the shading area of the ground floor façade walls was found when trees were within the distance 2 and 3 m away from the building.
Conceptualising sustainability through environmental stewardship and virtuous cycles—a new empirically-grounded model
Authors: Turnbull John W. , Clark Graeme F. , Johnston Emma L. 
Published: June 2021

AbstractHumans depend on earth’s ecosystems and in the Anthropocene, ecosystems are increasingly impacted by human activities. Sustainability—the long-term integrity of social–ecological systems—depends on effective environmental stewardship, yet current conceptual frameworks often lack empirical validation and are limited in their ability to show progress towards sustainability goals. In this study we examine institutional and local stewardship actions and their ecological and social outcomes along 7000 km of Australia’s coastline. We use empirical mixed methods and grounded theory to show that the combination of local and institutional stewardship leads to improved ecological outcomes, which in turn enhance social values and motivate further stewardship to form a virtuous cycle. Virtuous cycles may proceed over multiple iterations, which we represent in a new spiral model enabling visualisation of progress towards sustainability goals over time. Our study has important implications for collaborative earth stewardship and the role of policy in enabling virtuous cycles to ultimately realise sustainable futures.
A simple and effective algorithm for the maximum happy vertices problem
Authors: Ghirardi Marco , Salassa Fabio 
Published: June 2021

AbstractIn a recent paper, a solution approach to the Maximum Happy Vertices Problem has been proposed. The approach is based on a constructive heuristic improved by a matheuristic local search phase. We propose a new procedure able to outperform the previous solution algorithm both in terms of solution quality and computational time. Our approach is based on simple ingredients implying as starting solution generator an approximation algorithm and as an improving phase a new matheuristic local search. The procedure is then extended to a multi-start configuration, able to further improve the solution quality at the cost of an acceptable increase in computational time.

Abstract
Purpose
To report healthcare resource use and associated costs in controlled versus uncontrolled carcinoid syndrome (CS) in patients with neuroendocrine tumours.

Methods
A cross-sectional, non-interventional multicentre study was conducted with retrospective data analysis. Resource use was compared between two patient groups: those with controlled CS (> 12 months with no uncontrolled CS episodes) and uncontrolled CS (< 12 months since last uncontrolled episode). Patients were matched for age, sex, and origin and grade of tumour. When no matching patients were available, data from deceased patients were used. Information on healthcare resource use came from review of medical records, patient history and physician reports. Working capacity was assessed using the Work Productivity and Activity Impairment General Health questionnaire.

Results
Twenty-six university hospitals in Spain participated, between July 2017 and April 2018. 137 patients were enrolled; 104 were analysed (2 groups of 52). Patients with uncontrolled CS had 10 times more emergency department (ED) visits (mean 1.0 vs 0.10 visits; P = 0.0167), were more likely to have a hospital admission (40.4% vs 19.2%; P = 0.0116) and had longer hospital stays (mean 7.87 vs 2.10 days; P = 0.0178) than those with controlled CS. This corresponded to higher annual hospitalisation costs (mean €5511.59 vs €1457.22; P = 0.028) and ED costs (€161.25 vs €14.85; P = 0.0236). The mean annual total healthcare costs were 60.0% higher in patients with uncontrolled than controlled CS (P = NS).

Conclusion
This study quantifies higher health resource use, and higher hospitalisation and ED costs in patients with uncontrolled CS. Better control of CS may result 3in lower medical costs.
The Other, Altruism and Empathy. Variety of Prosocial Behavior
Authors: Cipriani Roberto 
Published: June 2021

AbstractSociology is par excellence the science of the other since relationality is the object of its approach. It is precisely from the relationship that is established with the other that various dynamics develop, which can be pro-social or counter-social, generating forms of altruism and selfishness, generosity and appropriation, acceptance and rejection, collaboration and competition. Altruism, in particular, has been the object of attention by Comte and Spencer in a universalistic perspective very different from the contemporary forms assumed by the phenomenon of globalization. Perhaps, it is only through the analysis of the modalities of altruism that we can understand well enough the reasons that produce attitudes and behaviours that are more or less favourable towards others. If we then combine altruism with the peculiar processes of the exercise of empathy, the sociological problem in its complexity becomes even more intriguing. It is not by chance that Daniel Batson has started a rather articulate discussion that tends to show how altruism is motivated by empathy.

Published: June 2021

AbstractIncreasing evidence has shown that astrocytes are implicated in regulating oligodendrocyte myelination, but the underlying mechanisms remain largely unknown. To understand whether microRNAs in astrocytes function in regulating oligodendroglial differentiation and myelination in the developing and adult CNS, we generated inducible astrocyte-specific Dicer conditional knockout mice (hGFAP-CreERT; Dicer fl/fl). By using a reporter mouse line (mT/mG), we confirmed that hGFAP-CreERT drives an efficient and astrocyte-specific recombination in the developing CNS, upon tamoxifen treatment from postnatal day 3 (P3) to P7. The Dicer deletion in astrocytes resulted in inhibited oligodendroglial differentiation and myelination in the developing CNS of Dicer cKO mice at P10 and P14, and did not alter the densities of neurons or axons, indicating that Dicer in astrocytes is required for oligodendrocyte myelination. Consequently, the Dicer deletion in astrocytes at P3 resulted in impaired spatial memory and motor coordination at the age of 9 weeks. To understand whether Dicer in astrocytes is also required for remyelination, we induced Dicer deletion in 3-month-old mice and then injected lysolecithin into the corpus callosum to induce demyelination. The Dicer deletion in astrocytes blocked remyelination in the corpus callosum 14 days after induced demyelination. Together, our results indicate that Dicer in astrocytes is required for oligodendroglia myelination in both the developing and adult CNS.
Toward Automated Support of Complaint Handling Processes: An Application in the Medical Technology Industry
Authors: Hake Philip , Rehse Jana-Rebecca , Fettke Peter 
Published: June 2021

AbstractComplaints about finished products are a major challenge for companies in the medical technology industry, where product quality is directly related to public health and therefore strictly regulated. In this paper, we examine how available data can be used to provide automated support to the complaint handling processes in the medical technology companies. We identify the automation potentials in the 8D reference process for complaint management and discuss their organizational and technical challenges. Using data from a large manufacturer of medical products, we show how partial process automation can be achieved in practice by designing, implementing, and evaluating a deep learning-based prototype for automatically suggesting a likely error code for future complaints, given their textual description. Our approach is able to assign the correct error code for more than 75% of all cases and outperforms the conventional classification approaches used as a baseline comparison. Our results show that partial automation of a complaint management process by means of deep learning can be achieved in practice.
Measuring Natural Hazard-Related Disasters through Self-Reports
Authors: Edwards Ben , Gray Matthew , Borja Judith B. 
Published: June 2021

AbstractExposure to multiple natural hazard-related disasters will become more common due to climate change. This article reports on the development and validation of a cumulative measure of exposure to natural hazard-related disasters (2013–2017) at the area level, and an individual-level measure of disaster impact using data from the Longitudinal Cohort Study on the Filipino Child and linked data from the International Disaster Database (EM-DAT). Caregiver reports of cumulative exposure to disasters had statistically significant associations with disasters reported by neighborhood officials and with disasters in EM-DAT. Using ecometric techniques we generated a reliable community average measure of exposure to natural hazard-related disasters. Based on neighbor but not individual self-reports this exogenous measure of disaster exposure in the local area was more strongly related to EM-DAT and official neighborhood reports than individual reports. To capture household variation we developed an individual-level measure of disaster impacts. Disaster impact was associated with measures of exposure (individual and community average), community ratings by officials, and EM-DAT but only moderately associated with the community average exposure. Both the community average and disaster impacts measures were associated with household income and the adequacy of income in households.

The current understanding of the bio-tribological behavior and mechanism involved in those devices is summarized. Recent advances in the improvement of tribological properties are examined. Challenges and future developments for the prospective of bio-tribological performance are highlighted.
Optimization of Inhibition Efficiency of a Schiff Base on Mild Steel in Acid Medium: Electrochemical and RSM Approach
Authors: Kumari Preethi , Lavanya M. 
Published: June 2021

AbstractThis research investigates the effect of Schiff base, namely,N'-[4-(dimethylamino) benzylidene]-4-hydroxybenzohydrazide (SB) on the corrosion mitigation of mild steel (MS) in hydrochloric acid medium (HCl) using potentiodynamic polarization (PDP) technique. The study highlights the effect of SB concentration, HCl concentration, and temperature on the corrosion current density (icorr) and inhibition efficiency (IE). The adsorption of SB onto the MS surface was justified with the support of kinetic and thermodynamic parameters. The morphological behavior of the MS surface was analyzed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). A blend of statistical study and interaction plots has been applied to obtain a thorough understanding of the corrosion parameters. Experimental results obtained by PDP measurements revealed that tested compounds had a good anti-corrosion capacity. The main and interaction effects of the parameters on the response were analyzed using Box-Behnken Design. An empirical model equation from experimental results elucidates the relationship among the variables. The optimized parameters for the maximum output were recognized. The maximum IE of 81.5 was predicted by RSM with temperature (A = 30 °C), HCl concentration (B = 0.5 M), and Inhibitor concentration (C = 0.0001 M). Using RSM, further analyses regarding individual and interaction effects between the variables can be more comprehensive. Few more parameters such as pH and time can be included in the future study.Graphic Abstract
