Published: April 2021

AbstractMonitoring and guiding multiple groups of students in face-to-face collaborative work is a demanding task which could possibly be alleviated with the use of a technological assistant in the form of learning analytics. However, it is still unclear whether teachers would indeed trust, understand, and use such analytics in their classroom practice and how they would interact with such an assistant. The present research aimed to find out what the perception of in-service secondary school teachers is when provided with a dashboard based on audio and digital trace data when monitoring a collaborative learning activity. In a vignette study, we presented twenty-one in-service teachers with videos from an authentic collaborative activity, together with visualizations of simple collaboration analytics of those activities. The teachers perceived the dashboards as providers of useful information for their everyday work. In addition to assisting in monitoring collaboration, the involved teachers imagined using it for picking out students in need, getting information about the individual contribution of each collaborator, or even as a basis for assessment. Our results highlight the need for guiding dashboards as only providing new information to teachers did not compel them to intervene and additionally, a guiding dashboard could possibly help less experienced teachers with data-informed assessment.

AbstractThe goal of this study was to measure food insecurity among families with children in a low-income district of Lima, Peru and to identify the formal and informal food resources available to them that may affect their food security status. In June-July 2019, we collected data from 329 randomly selected households in Villa El Salvador (Lima, Peru). Following a mixed methods approach, we found that the percentage of households using food assistance programs (FAPs) increased with increasing levels of food insecurity, but two FAPs were heavily used by households regardless of food (in)security. The main reasons for using FAPs included financial need, already being signed up in the program, and believing that the food was of nutritional value; the main reasons for non-use were finding the program unnecessary, dislike or poor perceived quality of the food, and not being able to sign up for the program. Similarly, informal food resources, such as buying food on credit or receiving food from someone outside the household, were incrementally used with increased levels of food insecurity. Our study clarifies the relationship between level of household food insecurity and FAP use – FAPs more commonly used by food insecure households were used because of financial need, whereas the FAPs most commonly used by food secure households were those with automatic enrollment. At a programmatic level, our research highlights the need for making nutritious and preferred foods available in FAPs and standardizing the application of enrollment criteria.
On the strength of the phase cross-correlation in retrieving the Green’s function information in a region affected by persistent aftershock sequences

AbstractAlthough research on seismic interferometry is now entering a phase of maturity, earthquakes are still the most troublesome issues that plague the process in real applications. To address the problems that arise from spatially scattered and temporally transient enormous earthquakes, preference is usually given to the use of time-dependent weights. However, small earthquakes can also have a disturbing effect on the accuracy of interpretations if they are persistently clustered right next to the perpendicular bisector of the line joining station pairs or in close proximity to one of the stations. With regard to the suppression of these cluster earthquakes, commonly used solutions for dealing with monochromatic microseismic cluster events (e.g., implementing a band-reject filter around a comparatively narrow frequency band or whitening the amplitude spectra before calculating the cross-spectrum between two signals) may not have the necessary efficiency since earthquake clusters are generally a collection of events with different magnitudes, each having its own frequency and energy contents. Therefore, the only solution left in such a situation is to use stronger non-linear time-dependent weights (e.g., square of the running average or one-bit normalization), which may cause Green’s function amplitude information to be lost. In this paper, by simulating the records of a benchmark earthquake MN5.2 with the help of empirical Green’s functions (EGF) obtained after the Ahar-Varzeghan Earthquake Doublet (MN6.4 and MN6.3), it is shown that the amplitude-unbiased phase cross-correlation is a relatively efficient approach in the face of the issues concerning long-standing cluster events.
No Infimum Gap and Normality in Optimal Impulsive Control Under State Constraints
Authors: Fusco Giovanni , Motta Monica 
Published: April 2021

AbstractIn this paper we consider an impulsive extension of an optimal control problem with unbounded controls, subject to endpoint and state constraints. We show that the existence of an extended-sense minimizer that is a normal extremal for a constrained Maximum Principle ensures that there is no gap between the infima of the original problem and of its extension. Furthermore, we translate such relation into verifiable sufficient conditions for normality in the form of constraint and endpoint qualifications. Links between existence of an infimum gap and normality in impulsive control have previously been explored for problems without state constraints. This paper establishes such links in the presence of state constraints and of an additional ordinary control, for locally Lipschitz continuous data.

Abstract
Purpose
Considering that breast cancer survivors (BCSs) have been dealing with unwanted job changes after diagnosis, this study aimed to investigate involuntary job changes (unwanted modifications in employment since diagnosis) and explore the association between job changes, involuntariness, and occupational development satisfaction in BCSs 5–6 years after diagnosis.

Methods
Data were drawn from the mixed-methods breast cancer patients’ return to work (B-CARE) study. We surveyed 184 female BCSs who were working at the time of study enrollment during hospitalization (T1), 10 weeks after discharge (T2), 40 weeks after discharge (T3), and 5–6 years after diagnosis (T4) and used descriptive measures and stepwise linear regression models for data analysis.

Results
The mean age of BCSs was 57 years. A total of 105 participants reported 410 job changes, of which 16.1% were reportedly (rather) involuntary. The most commonly reported involuntary changes were increased workload (15.2%) and increased scope of work (15.2%). In the final model, significant predictors of satisfaction with occupational development 5–6 years after diagnosis were age, state of health ΔT2–T3, state of health ΔT3–T4, and involuntariness of job changes.

Conclusions
Although the number of job changes alone is not substantially associated with BCSs’ satisfaction with occupational development, experiencing involuntary job changes is. Sociodemographic, disease-related, and work(place)-related factors may influence occupational satisfaction among BCSs.

Implications for Cancer Survivors
The findings indicate the importance of strengthening one’s ability to work as desired to prevent involuntary job changes and enable desired work participation in long-term support. The significance of workplace characteristics highlights the need for employers to encourage satisfying work participation.

Advancing the Circular Economy Through Organic by-Product Valorisation: A Multi-criteria Assessment of a Wheat-Based Biorefinery
Authors: Hagman Linda , Feiz Roozbeh 
Published: April 2021

Abstract
The transition toward a circular and biobased economy requires the biorefineries and bio-based industries to become more resource efficient with regards to their waste and by-product management. Organic by-products and waste streams can be an important source of value if used in feasible pathways that not only have a low environmental impact but also preserve or recover their energy, nutrients, and other potentially valuable components. Through development of a multi-criteria assessment framework and its application on a real case, this article provides methodological and practical insights on decision making for enhanced by-product management. Our framework includes 8 key areas and 18 well-defined indicators for assessing the environmental performance, feasibility, and long-term risk of each alternative. We studied six different management options for the stillage by-product of a Swedish wheat-based biorefinery and our results shows that the most suitable options for this biorefinery are to use the stillage either as animal fodder or as feedstock for local biogas production for vehicle fuel. This multi-criteria approach can be used by bio-based industrial actors to systematically investigate options for by-product management and valorisation for a circular and bio-based economy.

AbstractApple pomace (AP) is an abundant waste causing environmental problems. Therefore, the aim of the study was to evaluate the impact of AP on soil and plant growth under optimum and limited water availability. Two laboratory experiments were conducted to evaluate the impact of AP on: (i) hydrophysical properties, respiration, and N transformations in soil aggregates and (ii) the growth of wheat and faba bean in soil with addition of AP under optimum and limited water availability. The soil respiration rate increased rapidly after the introduction of AP, and the effect was dependent on the aggregate size. The reduction of nitrate and the increase in ammonium content in response to the AP addition were more pronounced in the larger aggregates. Reduced growth of wheat was noted in the dry soil supplemented with AP. Faba bean maintained its unchanged rate of growth after the application of AP, irrespective of water availability. An increase in the chlorophyll content was observed in faba bean grown in the AP-enriched soil. The apple pomace reduced the water wetting rate and increased the repellency index but did not affect the tensile strength of the soil aggregates. Disposal of AP as a soil amendment affects many indicators of soil quality. The application of AP to the soil has an impact on respiration and N transformations in the soil aggregates; moreover, it differently influences the growth of spring wheat and faba bean.
Impaired attentional and socio-affective networks in subjects with antisocial behaviors: a meta-analysis of resting-state functional connectivity studies
Authors: Dugré Jules Roger , Potvin Stéphane 
Published: April 2021

AbstractIn the past decade, there has been a growing interest in examining resting-state functional connectivity deficits in subjects with conduct and antisocial personality disorder. Through meta-analyses and literature reviews, extensive work has been done to characterize their abnormalities in brain activation during a wide range of functional magnetic resonance imaging (fMRI) tasks. However, there is currently no meta-analytical evidence regarding neural connectivity patterns during resting-state fMRI. Therefore, we conducted a coordinate-based meta-analysis of resting-state fMRI studies on individuals exhibiting antisocial behaviors. Of the retrieved studies, 18 used a seed-based connectivity approach (513 cases v. 488 controls), 20 employed a non-seed-based approach (453 cases v. 460 controls) and 20 included a correlational analysis between the severity of antisocial behaviors and connectivity patterns (3462 subjects). Meta-analysis on seed-based studies revealed significant connectivity deficits in the amygdala, middle cingulate cortex, ventral posterior cingulate cortex-precuneus, ventromedial and dorsomedial prefrontal cortex, premotor cortex, and superior parietal lobule. Additionally, non-seed-based meta-analysis showed increased connectivity in the ventral posterior cingulate cortex and decreased connectivity in the parietal operculum, calcarine cortex, and cuneus. Finally, we found meta-analytical evidence for negative relationship between the severity of antisocial behaviors and connectivity with the ventromedial prefrontal cortex. Functional characterization and meta-analytical connectivity modeling indicated that these findings overlapped with socio-affective and attentional processes. This further underscores the importance of these functions in the pathophysiology of conduct and antisocial personality disorders.
Georgian Washerwomen: tales of the tub from the long eighteenth century
Authors: Dyer Jenny 
Published: April 2021

AbstractWasherwomen in the Georgian period belonged, for the most part, to the small army of part-time and casual workers who found employment when and where they could. As handlers of one of the most coveted (as well as necessary) commodities of the period they were a focus of interest to a wide range of society and were growing in number as many householders came to rely less on resident domestic servants. Washerwomen were prime players in the ‘economy of makeshifts’, relying on a miscellany of supplementary activities to ‘get by’ and in which they showed both enterprise and agency.
Estimating lengths-of-stay of hospitalised COVID-19 patients using a non-parametric model: a case study in Galicia (Spain)

Published: April 2021

AbstractEstimating the lengths-of-stay (LoS) of hospitalised COVID-19 patients is key for predicting the hospital beds’ demand and planning mitigation strategies, as overwhelming the healthcare systems has critical consequences for disease mortality. However, accurately mapping the time-to-event of hospital outcomes, such as the LoS in the intensive care unit (ICU), requires understanding patient trajectories while adjusting for covariates and observation bias, such as incomplete data. Standard methods, such as the Kaplan-Meier estimator, require prior assumptions that are untenable given current knowledge. Using real-time surveillance data from the first weeks of the COVID-19 epidemic in Galicia (Spain), we aimed to model the time-to-event and event probabilities of patients’ hospitalised, without parametric priors and adjusting for individual covariates. We applied a non-parametric mixture cure model and compared its performance in estimating hospital ward (HW)/ICU LoS to the performances of commonly used methods to estimate survival. We showed that the proposed model outperformed standard approaches, providing more accurate ICU and HW LoS estimates. Finally, we applied our model estimates to simulate COVID-19 hospital demand using a Monte Carlo algorithm. We provided evidence that adjusting for sex, generally overlooked in prediction models, together with age is key for accurately forecasting HW and ICU occupancy, as well as discharge or death outcomes.

AbstractObjective:To investigate the association between the Children’s Dietary Inflammatory Index (C-DIITM) scores and atherogenic risk in Brazilian schoolchildren.Design:A cross-sectional representative study. Three 24-h dietary recalls were performed to evaluate food consumption and to calculate C-DII scores. Blood samples were collected for the lipid profile analysis (serum total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol and triglycerides (TAG)) and to determine atherogenic indexes (Castelli risk indexes I and II, lipoprotein combined index (LCI), and atherogenic index of plasma and atherogenic coefficient (AC)). A semi-structured questionnaire was used to obtain sociodemographic characteristics and screen time. Body fat was assessed by dual-energy X-ray absorptiometry. We compared the distributions of outcomes by C-DII categories using multivariable linear regression.Setting:Viçosa, Minas Gerais, Brazil.Participants:Three hundred seventy-eight children between the ages of 8 and 9 years.Results:The mean C-DII score was 0·60 ± 0·94, and the prevalence of dyslipidaemia was 70 %. Children with hypercholesterolaemia and hypertriglyceridaemia had higher C-DII scores. The C-DII was directly associated with atherogenic risk. Every 1 sd of C-DII was associated with a 0·07 (0·01, 0·13), 1·94 (0·20, 3·67), 0·06 (0·002, 0·12) and 0·12 (0·02, 0·22) units higher TC:HDL cholesterol ratio, LCI, AC and accumulation of altered dyslipidaemia markers (high TC + high LDL-cholesterol + high TAG + low HDL-cholesterol), respectively.Conclusions:Dietary inflammatory potential, as estimated by the C-DII, is directly associated with atherogenic risk in Brazilian schoolchildren. This results reinforce the importance of effective nutritional policies to promote healthy eating habits and improve children’s lipid profiles.
Mandatory annuitization and money's worth: evidence from Singapore
Authors: Fong Joelle H. , Li Jackie 
Published: April 2021

AbstractThis paper examines the impact of uncertainties in the future trends of mortality on annuity values in Singapore's compulsory purchase market. We document persistent population mortality improvement trends over the past few decades, which underscores the importance of longevity risk in this market. Using the money's worth framework, we find that the life annuities delivered expected payouts valued at 1.019–1.185 (0.973–1.170) per dollar of annuity premium for males (females). Even in a low mortality improvement scenario, the annuities provide an expected value exceeding 0.950. This suggests that participants in the national annuity pool have access to attractively priced annuities, regardless of sex, product, and premium invested.

Published: April 2021

AbstractThe yield of durum wheat extremely reduces in response to salinity stress because of several variations in biochemical, physiological and molecular traits in this unfavorable condition. According to the agro-physiological traits under salinity stress, the most resistant and sensitive cultivars were selected from 10 genotypes of durum wheat over a period of 2 years. Afterwards, the molecular, biochemical, and physiological traits in these two genotypes were evaluated. The seedlings (3–4 leaves) were exposed to salinity through irrigating with 0.5 × Hoagland solution containing 200 mM NaCl until physiological maturity. Principal components analysis for the agronomic characteristics and stress resistance index led to identifying Behrang and Arya as the most tolerant and sensitive genotypes, respectively. In these two genotypes in response to salinity stress, osmolyte contents (proline, total soluble carbohydrates and total soluble proteins) and enzymatic antioxidant defence system activities (ascorbate peroxidase, catalase and guaiacol peroxidase) were much higher in the most tolerant genotype than those of the sensitive cultivar. Moreover, the most tolerant genotype showed less amount of oxidative stress parameters (hydrogen peroxide, electrolyte leakage, malondialdehyde and other aldehydes) than the sensitive one.Pyrroline-5-carboxylate reductase(P5CR) anddelta-1-pyrroline-5-carboxylate synthase(P5CS) genes expression increased under salinity stress (considering much higher increase in the most tolerant cultivar). Also, proline content was shown to have a significant positive correlation withP5CSandP5CRgenes expression levels. Our result not only identified Behrang cultivar as a superior genotype for durum wheat breeding programs, but also represented several efficient mechanisms involved in salt tolerance.

AbstractDrought tolerance is a highly complex trait and one of the important components of yield stability in wheat. An experiment was therefore conducted to study the drought tolerance status of 14 high-yielding wheat varieties based on morphological characteristics under a randomized complete block design following factorial arrangement with three replications. Variety × Treatment × Year interactions of wheat genotypes were studied for various morphological traits under normal and drought stress conditions for 2 years in plants grown in pots. Significant differences were observed among the 14 varieties of wheat. Sutlej-86 was found to be highly affected by drought, with maximum reductions in plant height, spike length and number of spikelets/spike. The variety with the maximum tolerance to drought was Bahawalpur-97; this variety also had the lowest reductions in the number of fertile tillers/plant, the number of spikelets/spike, spike weight, the number of grains/spike, 1000-grain weight, grain yield/spike, total biomass and stress susceptibility and tolerance indices. Stronger correlations among the studied attributes under drought stress over normal conditions further highlighted drought stress adversities. The studied traits are thus recognized as drought tolerance indicators for varietal selection, and varieties showing less reduction under drought could be used as a standard check in breeding programmes to identify lineages with drought tolerance and could be recommended for drought-stressed areas.
