Abstract
Introduction
Eastern migratory monarch butterflies (Danaus plexippus) have declined over 80% in recent years, but little is known about fall reproduction in the southern U.S. where monarchs may compete with queen butterflies (Danaus gilippus).

Aims/methods
We provide data on the survival to third instar, associated arthropods, and phenology of fall breeding monarchs and queens in Texas.

Results
Monarch and queen survival was relatively high, but varied among years. Oleander aphids (Aphis nerii), spiders, and red imported fire ants (Solenopsis invicta) had minor negative effects on survival. The abundance of monarchs and queens on the study site peaked three to four weeks before the main passage of monarchs in the area. Queens had similar phenology and exhibited a migratory pattern similar to monarchs but on a smaller scale.

Discussion
Survival of fall monarchs is relatively high and potentially important for winter roost recruitment. Fall survival was not greatly affected by any particular arthropod taxon, but may be affected by precipitation. Fall reproduction is a response to available host plants and its timing enables pupae to eclose in time for migration to winter roosts.

Implications for insect conservation
Management of Asclepias viridis and other native milkweeds to facilitate fall reproduction could facilitate recovery of monarchs if it buffers variable productivity further north. Management should use mowing and burn schedules that promote high quality host plants. Populations of queens should be monitored for their potential to compete with monarchs especially in response to the potential impacts of parasite resistance and climate change.

AbstractYounger breast cancer survivors (YBCS) consistently report poorer quality of life (QOL) than older survivors. Increasing physical activity (PA) may improve QOL, but this has been understudied in YBCS. This single arm pilot study evaluated the feasibility and acceptability of a 3-month, peer-delivered, remote intervention to increase PA and improve QOL in YBCS. Data were collected from October 2019 – July 2020. Participants (n = 34, 43.1 ± 5.5 years old, 46 ± 34.4 months post-diagnosis, BMI = 30.2 ± 7.4 kg/m2) completed six video sessions with a trained peer mentor; self-monitored PA with a Fitbit activity tracker; and interacted with a private Fitbit Community for social support. At baseline, 3-and 6-months, participants completed QOL questionnaires and PA was measured through accelerometer (moderate-to-vigorous PA [MVPA]) and self-report (strength and flexibility). A parallel mixed-methods approach (qualitative interviews and quantitative satisfaction survey at 3-months) explored intervention feasibility and acceptability. One-way repeated-measures ANOVAs examined impacts on PA and QOL at 3-and 6-months. The intervention was feasible as evidenced by efficient recruitment, high retention, and adherence to intervention components. Remote delivery, working with a peer mentor, and using Fitbit tools were highly acceptable. From baseline to 3-months, participants increased time spent in objectively measured MVPA, strength, and flexibility exercises, and reported meaningful improvements to body image, fatigue, anxiety, and emotional support. A fully remote, peer-to-peer intervention is an acceptable and promising strategy to increase PA and improve QOL in YBCS. Refinements to the intervention and its delivery should be further assessed in future studies, toward the goal of disseminating an evidence-based, scalable intervention to the growing number of YBCS.Trial registration Prospectively registered as NCT04064892.

AbstractSeasonal and interannual variabilities of sea-ice area in the Southern Ocean were examined using daily sea-ice concentration and ice velocity products for 2003–2019, derived from Advanced Microwave Scanning Radiometer for EOS (AMSR-E) and AMSR2 data. This study quantified the contributions to changes in the sea-ice area due to sea-ice transport and local processes, including ice formation/melting and ice deformation. Regional differences in the processes of seasonal advance and retreat of sea ice were elucidated. In most regions, sea-ice area increases mainly due to new ice formation in the marginal ice zone during autumn and winter. However, in the Amundsen–Bellingshausen seas, ice melting occurs in the marginal ice zone, even during winter, and expansion of the ice cover is attributable mainly to off-ice transport. With regard to interannual variability, the maximum ice area for each year is highly correlated with increase of ice area attributable to the ice formation in the marginal ice zone. Revealed processes that controls sea-ice changes could help improve our understanding of the sea-ice response to climate change.
Should We Cheer Together? Gender Differences in Instantaneous Well-being: An Application to COVID-19 Lockdowns
Authors: Giménez-Nadal José Ignacio , Molina José Alberto , Velilla Jorge 
Published: December 2022

AbstractThe COVID-19 pandemic has confined millions in their homes, an unprecedented opportunity to spend more time together with family members. This paper explores subjective well-being in the uses of time for US and UK workers, differentiating between solo activities and activities done with family members, at home and outside the home. Using American and British time use surveys, we compute the instant utility associated with paid work, unpaid work, leisure, and childcare activities. OLS regressions on both men and women show that workers prefer joint leisure to solo leisure, and that significant differences exist for solo and joint market work and housework, between the sexes. Despite that, the effect magnitudes are relatively low. Furthermore, we simulate a strict lockdown situation by replacing where and with whom worker episodes would be, based on mid-2020 strict confinements. Results suggest diverging effects, since more time with the spouse/partner and children, and less time with others, seems to increase the experienced wellbeing of women, compared to that of men. The simulation exercise also reveals asymmetric effects in the US and in the UK. The conclusions of this paper may help in assessing the psychological consequences of COVID-19 lockdowns, beyond the negative economic and labour market consequences.

AbstractThe negative consequences of perceived ethnic discrimination on adolescent adjustment are well documented. Less is known, however, about the consequences of discriminatory climates in school, beyond the individual experiences of discrimination. This study investigated whether a perceived discriminatory climate in school is associated with lower academic performance across adolescents from ethnic minority and majority groups, and which psychological mechanisms may account for this link. Using the 2018 Programme for International Student Assessment (PISA) data, the participants were 445,534 adolescents (aged 15–16, 50% girls) in 16,002 schools across 60 countries. In almost all countries, a discriminatory climate—i.e., student perceptions of teachers’ discriminatory beliefs and behaviors in school—was associated with lower math and reading scores across all pupils, although minorities perceived a more discriminatory climate. Lower school belonging and lower values attributed to learning partially mediated these associations. The findings demonstrate that schools’ ethnic and racial climates predict standardized academic performance across schools and countries among pupils from both ethnic majority and minority groups.

Published: December 2022

AbstractEutectic AlSi12, commonly used in casting and in additive manufacturing, is investigated with Fast Differential Scanning Calorimetry to determine the impact of different cooling rates from the liquid state upon the apparent specific heat capacity on subsequent heating. A heat flow correction strategy is developed and refined for the reliable and precise measurement of sample heat flow using chip sensors and assessed by the evaluation of results on pure (99.999%) aluminium. That strategy is then applied to the study of the AlSi12 eutectic alloy, and rate-dependent perturbations in the measured apparent specific heat capacity are discussed in terms of Si supersaturation and precipitation. Several cooling rates were implemented from − 100 to − 30,000 K s−1, and subsequent heating ranged from + 1000 to + 30,000 K s−1. After rapid cooling, a drop in AlSi12 apparent specific heat capacity is found on heating above ~ 400 °C; even at rates of + 10,000 K s−1, a result which has high relevance in metal additive manufacturing where similarly fast temperature cycles are involved. The Literature data, temperature modulated DSC and CALPHAD simulations on the heat capacity of AlSi12 are used to provide comparative context to the results from Fast Differential Scanning Calorimetry.

Published: December 2022

Abstract
Context
Field boundary (FB) establishment and conservation have been promoted to enhance biodiversity in agroecosystems. However, weeds can colonize these areas during the revegetation process, which might be a problem for adjacent fields. Data is necessary to facilitate acceptance of these structures by farmers.

Objectives
This work takes advantage of a unique opportunity to describe the plants establishing in a set of new FBs. The main aims were to describe species composition in a six-year period and to detect if FBs can be a weed source for surrounding agricultural land.

Methods
Data was collected in ten FBs in a semi-arid environment in north-eastern Spain (eight metres in width) created from 2003 to 2007 in a farm owned by the CITA Research Centre. Vegetation was recorded in spring in years 2006–08 and 2011–13 covering a time sequence that ran from establishment until an age of 10 years. The same data was recorded in adjacent winter cereal field centres (FCs) and existing boundaries of neighbouring commercial farms (CFBs) established decades earlier.

Results
Plant ground cover and total species richness increased rapidly in the FBs, remaining stable after approximately the fourth year. Different analysis confirm that vegetation in the FBs was different from that found in the FCs and CFBs; 10 years was probably a too short period for the FBs to develop a similar vegetation composition to that of the CFBs.

Conclusions
Data of this example support that establishing new FBs can promote plant diversity without infesting the surrounding fields with weeds.
Particle breakage and morphology changes of calcareous sands under one-dimensional compression loading

Published: December 2022

AbstractParticle breakage and the corresponding change of morphology are two key factors governing the mechanical behavior of calcareous sands in offshore geotechnical engineering constructions. To reveal the characteristics of these two factors, oedometer tests on calcareous sands have been performed in this study. The materials were sampled from the South China Sea with a homogenous composition but different particle size ranges and relative densities. In these tests, the dynamic imaging analysis (DIA) by Microtrac PartAn3Dand acoustic emission (AE) techniques were employed to investigate the evolution of particle morphology and characteristics of AE signaling associated with the material deformations, respectively. The compressive deformation of calcareous sands was mainly induced by the particle rearrangement and particle breakage which are effectively irreversible plastic deformations. The irregular particle shape has led to strong interparticle filling and interlocking effects, which affected the particle slippage and rearrangement significantly during the deformation. The intensity and type of AE-triggering micro-mechanical behaviors were characterized by AE ringdown counts (RDC) and peak frequency, respectively. The RDC values concentrated primarily in the compression stage and increased rapidly under the normal stress of 400–3200 kPa. The RDC values increased with the increase of particle size but decreased with the increase of initial relative density. The compressive deformation and breakage characteristics of calcareous sands are consistent with the existing acoustic emission laws.

Published: December 2022

ZusammenfassungFür die Universität erwiesen sich digitale Technologien während der COVID-19-Pandemie als zentrales Element der Krisenbewältigung. Das gilt insbesondere für den Bereich der Lehre. Aus Sicht der „Multi-Level-Perspektive“ (Geels 2004) eröffnen die disruptiven Auswirkungen der Pandemie ein „Window of Opportunity“ für einen tiefgreifenden und dauerhaften soziotechnischen Wandel. Daran anschließend wird in diesem Artikel die Frage erörtert, wie Angehörige der Universität die zukünftige Bedeutung digitaler Technologien einschätzen. Auf Basis qualitativer, empirischer Erhebungen lassen sich fünf Szenarien herausarbeiten, die in je unterschiedlicher Weise digitale Zukünfte skizzieren. Die Analyse dieser Zukunftsszenarien fragt jedoch nicht nach deren Eintrittswahrscheinlichkeit, sondern nach ihrer Wünschbarkeit. Auf diese Weise kann gezeigt werden, mit welchen Begründungen argumentiert wird, warum die weiterführenden Digitalisierungsschritte an der Universität unternommen oder auch unterlassen werden sollten. Zum gegebenen Zeitpunkt ist es nicht einschätzbar, welche Szenarien digitaler Universitäten sich letztlich durchsetzen werden. Nicht zuletzt deshalb versteht sich dieser Artikel als Grundlage für eine breite Debatte, die es erst zu führen gilt.

Abstract Examination of post-mortem brain tissues has previously revealed a strong association between Parkinson’s disease (PD) pathophysiology and endoplasmic reticulum (ER) stress. Evidence in the literature regarding the circulation of ER stress-regulated factors released from neurons provides a rationale for investigating ER stress biomarkers in the blood to aid diagnosis of PD. The levels of ER stress-regulated proteins in serum collected from 29 PD patients and 24 non-PD controls were measured using enzyme-linked immunosorbent assays. A panel of four biomarkers, protein disulfide-isomerase A1, protein disulfide-isomerase A3, mesencephalic astrocyte-derived neurotrophic factor, and clusterin, together with age and gender had higher ability (area under the curve 0.64, sensitivity 66%, specificity 57%) and net benefit to discriminate PD patients from the non-PD group compared with other analyzed models. Addition of oligomeric and total α-synuclein to the model did not improve the diagnostic power of the biomarker panel. We provide evidence that ER stress-regulated proteins merit further investigation for their potential as diagnostic biomarkers of PD.

Published: December 2022

AbstractConstruction on swelling soil is a major challenge to geotechnical engineers all around the world. This type of soil has a quite complex behavior as they undergo the category of problematic soils. The seasonal variations in the climate cause swelling and shrinkage, affecting soil’s water retention. The prediction of future climate change will worsen this problem, increasing the importance of the matter. The attention has been directed to experimental modeling and field investigations. In previous references, this problem was targeted by adding additives which are relatively expensive and non-environment friendly. In this study, waste and recycled materials are used in the lab to enhance the undesirable expansive soil characteristics to keep the environment clean and sustainable and reduce pollution. The additives are selected not only for its availability and cheapness but also to reduce the damage of environment due to disposal of waste. Therefore, the aim of study is to observe the behavior of expansive soils when mixing with various percentages of sodium chloride (NaCl) and lime sludge (LS). The percentages used in this work to determine the swelling properties of expansive soil were 1%, 2%, and 3% NaCl by weight with 3%, 6%, 9%, 10%, 12%, 15%, and 20% of LS by weight. The experimental tests held in the laboratory were liquid limit (LL), plastic limit (PL), free swell (FS), plasticity index (PI), swelling pressure, swelling and infiltration test, and physical models. The results show that by increasing the percentage of NaCl and LS, a significant improvement is obvious to the swelling properties of soils. Added to that, a decrease in PI of the swelling soil is clearly observed which reflects a decrease in swelling pressure and free swell of the swelling soil.

AbstractOne of the most important fossil fauna localities in the Baikal region is the Tagay section. It is located on the shore of Tagay bay at the northwestern coast of Olkhon Island in the Baikal Lake and consists of two different exposures, Tagay-1 and Tagay-2. The Tagay-1 section exposes predominantly lake sediments of Miocene age and contains a faunal complex. The Tagay-2 section is composed of slope wash and subaerial sediments of Early Pleistocene (Calabrian?) age with remains of small mammals. A total of 95 samples for palaeomagnetic studies were taken in both sections. Magnetic susceptibility (MS), its frequency dependence (Fd) and anisotropy were measured from all samples. The stable component of the natural remanent magnetization (NRM) was obtained using stepwise alternating field (AF) demagnetization. The magnetic polarity pattern was constrained for the Tagay-1 section. It includes an extended zone of reversed polarity, complicated by three normal subzones of minor rank. Palaeontological data allow correlation of the Tagay-1 pattern with the magnetic chrons C5Dn to C5Cn.1n (late Burdigalian – early Langhian). Palaeomagnetic directions in the upper part of the Tagay-2 section are randomly distributed due to intensive slope-wash processes resulted in mechanical perturbation of the sediments. The lower part of Tagay-2 section demonstrates only reversed polarity, although the scatter of directions is quite large due to landsliding. This reversed interval may be correlated with the Matuyama chron between Cobb Mountain and Olduvai subchrons. Synchronous increase of MS and Fd values in palaeosols suggests a pedogenic (or “Chinese”) mechanism influencing magnetic properties of the Tagay-2 section under warm palaeoclimatic conditions.
Wetlands as a Local Scale Management Tool to Reduce Algal Growth Potential
Authors: Borgström Anna , Hansson Lars-Anders , Sjöstedt Johanna 
Published: December 2022

AbstractRecent land-use changes have led to a significant loss of natural wetlands worldwide resulting in increased amounts of organic and inorganic compounds reaching lakes and coastal areas. In turn, this has led to an increased algal growth, and subsequently the risk of algal blooms and deteriorated water quality. The capacity of wetlands to retain nutrients is well-known, suggesting that constructed wetlands may be a potential management strategy to mitigate algal blooms in downstream waters, although little is known about seasonal variation in reduction of algal growth potential. Therefore, in a long-term study, we experimentally evaluated the efficiency of seven wetlands to reduce the algal growth potential by comparing the growth in cultures containing 50:50 wetland water from the inlet or outlet and water from a eutrophic lake as a standard inoculum. We show that the majority of the wetlands have a considerable potential to reduce algal growth potential, with up to 89% for cyanobacteria and 73% for green algae. However, there were strong temporal variations in efficiency within, as well as between wetlands. Specifically, we show that the potential to reduce algal growth (standardized conditions) was generally higher in winter than in summer. In addition, the wetlands showed different efficiency in reducing the growth potential of cyanobacteria and green algae. Taken together, our results show that wetlands have a considerable potential to reduce algal growth potential, suggesting that they are an efficient local-scale tool in reducing the risk of algal blooms especially from a future climate change perspective.
Correlation between free fatty acids content and textural properties of Gouda cheese supplemented with denatured whey protein paste

Published: December 2022

AbstractIn this study, the denatured whey protein paste (DWPP) was used to improve the texture characterizations of Gouda cheese. Five treatments of cheese were manufactured by adding 0, 1, 2, 3 and 4% of DWPP to cheese curd. Fortification of Gouda cheese with DWPP increased values of moisture, salt in moisture, water-soluble nitrogen/total nitrogen and non-protein nitrogen/total nitrogen whereas decreased values of density and free oil. The cheese contained DWPP was lighter and more yellowish compared to the control. The cheese samples contained 1 and 2% DWPP exhibited a significant increase in hardness, cohesiveness, springiness, gumminess and chewiness values while, the cheese samples that contained 3 and 4% DWPP exhibited a significant decrease. Adding DWPP to cheese lowered saturated fatty acids and raised unsaturated fatty acid (USFA) values which partially caused a lowering in cheese hardness at high levels of DWPP because of the low melting points of USFA. Based on these results, supplementation of Gouda cheese with 1 or 2% DWPP improved the texture properties.
