The impact of Sosnowsky’s Hogweed on feeding guilds of birds
Authors: Grzędzicka Emilia , Reif Jiří
Published: May 2021

Plant invasions alter bird community composition worldwide, but the underlying mechanisms still require exploration. The investigation of feeding guild structure of bird communities can be informative in respect to the potential impact of invasion features on the availability of food for birds. For this purpose, we focused on determining the influence of the invasive Sosnowsky’s HogweedHeracleum sosnowskyion the abundance of birds from various feeding guilds. In spring and summer 2019, birds were counted three times on 52 pairs of sites (control + Heracleum) in southern Poland, at various stages of Sosnowsky’s Hogweed development (i.e. sprouting, full growth and flowering, all corresponding to respective bird counts). We have shown that the presence of invader negatively affected the abundance of birds from all feeding guilds. However, a closer examination of the invaded sites uncovered that responses of particular guilds differed in respect to development stages expressed by a set of characteristics of the invader. Ground and herb insectivores were more common on plots with a higher number of the invader, while the abundance of bush and tree insectivores was negatively correlated with hogweeds’ height. Granivores were not affected by the invader’s features, while the abundance of omnivores was negatively related to the number of flowering hogweeds. Besides showing the general negative impact of the invader on different feeding guilds, our research has shown that certain aspects of Sosnowsky’s Hogweed invasion may support or depress occurrence of different birds on invaded plots. Knowledge of these aspects may facilitate our capacity for coping with challenges the invasive plants put in front of bird conservationists.
Leveraging Artificial Intelligence in Marketing for Social Good—An Ethical Perspective
Authors: Hermann Erik
Published: May 2021

Artificial intelligence (AI) is (re)shaping strategy, activities, interactions, and relationships in business and specifically in marketing. The drawback of the substantial opportunities AI systems and applications (will) provide in marketing are ethical controversies. Building on the literature on AI ethics, the authors systematically scrutinize the ethical challenges of deploying AI in marketing from a multi-stakeholder perspective. By revealing interdependencies and tensions between ethical principles, the authors shed light on the applicability of a purely principled, deontological approach to AI ethics in marketing. To reconcile some of these tensions and account for the AI-for-social-good perspective, the authors make suggestions of how AI in marketing can be leveraged to promote societal and environmental well-being.
Recovery and Recrystallization Behaviors of Ni–30 Mass Pct Fe Alloy During Uniaxial Cold and Hot Compression
Authors: Yamaguchi Itsuki , Yonemura Mitsuharu
Published: May 2021

The recovery and recrystallization behaviors of the high-temperature γ-phase of carbon steel during deformation strongly affect the mechanical properties of steel. However, it is difficult to evaluate such behaviors at a high temperature. This study proposes the deformation behavior of the high-temperature γ-phase of low-carbon steel based on the quantitative observation of dislocation density and vacancies in the Ni–30 mass pct Fe alloy. This alloy was used because its stacking fault energy (60 to 70 mJ m-2) is similar to that of low-carbon steel. Uniaxial compression tests were conducted at a strain rate of 10−3 s−1 and 1473 K (1200 °C) for dynamic recrystallization and at 293 K (20 °C) for work hardening. The compression process was interrupted at different strain values to systematically investigate microstructural changes. The changes in work hardening, recovery, and recrystallization behaviors were obtained from the true stress–true strain curves of the uniaxial compression tests. Further, the microstructure changes during cold and hot uniaxial compression were investigated from the viewpoint of lattice defects by X-ray diffraction, positron annihilation analysis, transmission electron microscopy, and electron backscatter diffraction to comprehend the work hardening, dynamic recovery (DRV), and dynamic recrystallization (DRX). This study helps understand the DRV, DRX, and work hardening behaviors in the γ-phase of the Ni–30 mass pct Fe alloy during cold and hot compression.
Increasing physical activity levels following treatment for cervical cancer: an intervention mapping approach
Authors: Millet Nessa , McDermott Hilary J. , Moss Esther L. , Edwardson Charlotte L. , Munir Fehmidah
Published: May 2021

Purpose

The purpose of this study was to utilise the intervention mapping (IM) protocol as a framework with which to develop an intervention underpinned by relevant behaviour change theory to promote physical activity (PA) following treatment for cervical cancer.

Methods

The six steps of the IM protocol were followed. A qualitative semi-structured interview study and a rapid review of the literature were conducted along with the development of a logic model of the problem and a logic model of change to inform intervention development.

Results

An intervention was developed which aims to increase PA levels following treatment for cervical cancer, tailored to address key findings from the IM needs assessment. These include embedding behavioural and social strategies that help participants to overcome perceived barriers to PA participation; goal setting strategies to gradually increase PA levels with a view of reaching relevant PA guidelines for cancer survivors and feedback to encourage self-assessment of well-being and PA capability.

Conclusion

This study maps the development of a novel PA intervention for those who have been treated for cervical cancer. The use of a systematic development framework was necessary as little insight exists regarding PA preferences after treatment for cervical cancer.

Implications for Cancer Survivors

PA behaviour is associated with positive physical and psychological health outcomes for cancer survivors. Optimising targeted promotion of PA behaviour following treatment for cervical cancer may result in an enhanced survivorship experience through increased PA behaviour and improved quality of life (QOL).
Development of a measure of kindness
Authors: Youngs Donna E. , Yaneva Miroslava A. , Canter David V.
Published: May 2021

In the spirit of the growing developments in positive psychology, there is an increasing interest in how kind people are to each other. Yet, this area lacks any strong psychometric instrument. An initial exploratory study demonstrated that a 40-item questionnaire, completed by 165 people, revealed distinct aspects of kindness when subjected to multivariate analysis. A subsequent study is reported, using the structure of the exploratory results to further clarify the conceptual framework (Study 1). The revised 45-item questionnaire was administered to 1039 individuals from the general British population. Smallest Space Analysis of the variables, supported by Factor analysis, confirmed the hypothesis of two facets to kindness, the psychological source of the action (from principles or empathy), and the form of expression (through psychological involvement or following social prescription. It also revealed an additional general, core kindness, labelled Anthropophilia. Reliable scales derived from the combinations of the two elements from each facet were identified: Affective-Socially Prescribed; Affective-Proactive; Principle-Socially Prescribed and Principle-Proactive. Intercorrelations between the scales revealed that they measure different modes of kindness. Comparisons between male and female respondents provided external validity for the questionnaire. Study 2 (N = 251) reported that the scales measure independent dimensions when correlated with similar and dissimilar concepts.
The Legacies of Tennis Champions Althea Gibson, Arthur Ashe, and the Williams Sisters Show the Persistence of America’s Race Obstacles
Authors: Destin Yven , Dyer Ervin
Published: May 2021

Black athletes have had to express a double consciousness of being American and being Black. By exploring the biographies of pioneering tennis figures—Althea Gibson, Arthur Ashe, and the Williams sisters—Venus and Serena—one can look at their encounters with racism and their quests for self-respect and explore the social implications of race in the USA. To understand race and its complications on the world in which black tennis players navigate, we broadly look at racial discrimination in their lives using the lens of sociological concepts such as “the color line” hypersegregation and “American Apartheid;” the controlling image thesis and respectability politics, and class mobility in and outside the black community. The concepts connect to illuminate the racial constructs and structures the players operated in and which shaped in the process of becoming a sports champion. Through their biographies, we argue that it is possible to interrogate the ways in which America’s longstanding racial policies, prejudices, and perspectives have had a persistent impact on not only the lives of black tennis players, but the lives of black Americans.
Enhancing Sustained Attention

Published: May 2021

Arguably, automation is fast transforming many enterprise business processes, transforming operational jobs into monitoring tasks. Consequently, the ability to sustain attention during extended periods of monitoring is becoming a critical skill. This manuscript presents a Brain-Computer Interface (BCI) prototype which seeks to combat decrements in sustained attention during monitoring tasks within an enterprise system. A brain-computer interface is a system which uses physiological signals output by the user as an input. The goal is to better understand human responses while performing tasks involving decision and monitoring cycles, finding ways to improve performance and decrease on-task error. Decision readiness and the ability to synthesize complex and abundant information in a brief period during critical events has never been more important. Closed-loop control and motivational control theory were synthesized to provide the basis from which a framework for a prototype was developed to demonstrate the feasibility and value of a BCI in critical enterprise activities. In this pilot study, the BCI was implemented and evaluated through laboratory experimentation using an ecologically valid task. The results show that the technological artifact allowed users to regulate sustained attention positively while performing the task. Levels of sustained attention were shown to be higher in the conditions assisted by the BCI. Furthermore, this increased cognitive response seems to be related to increased on-task action and a small reduction in on-task errors. The research concludes with a discussion of the future research directions and their application in the enterprise.

Authors: Ren Zhonghe , Fang Fengzhou , Yan Ning , Wu You
Published: May 2021

Machine vision significantly improves the efficiency, quality, and reliability of defect detection. In visual inspection, excellent optical illumination platforms and suitable image acquisition hardware are the prerequisites for obtaining high-quality images. Image processing and analysis are key technologies in obtaining defect information, while deep learning is significantly impacting the field of image analysis. In this study, a brief history and the state of the art in optical illumination, image acquisition, image processing, and image analysis in the field of visual inspection are systematically discussed. The latest developments in industrial defect detection based on machine vision are introduced. In the further development of the field of visual inspection, the application of deep learning will play an increasingly important role. Thus, a detailed description of the application of deep learning in defect classification, localization and segmentation follows the discussion of traditional defect detection algorithms. Finally, future prospects for the development of visual inspection technology are explored.
Seismic vulnerability assessment and fragility curves for a multistorey gallery arch bridge

Published: May 2021

The masonry bridges on the Kalka Shimla Mountain Railway line, which have multiple arch galleries in the form of Roman aqueducts, are spectacular. The Kalka Shimla Mountain Railway line is situated in severe seismic zones (Indian Standard 1893:2016). This research assesses the seismic vulnerability of masonry arch Bridge No. 541 situated on the Kalka Shimla Mountain Railway line. This bridge is the tallest on the route. In particular, it assesses the seismic vulnerability of the bridge using finite element (FE) analysis. For this purpose, an FE model for the bridge is developed using the ABAQUS FE-based environment. The experimental field study conducted on the bridge using an ambient vibration test (AVT) and dynamic parameters (frequency and mode shapes) is evaluated by operational modal analysis (OMA). Further, the FE model is updated by modifying the elastic mechanical property of the stone masonry to match the analytical modal frequency with the results of the AVT and OMA. The updated model is then used to perform a pushover analysis and nonlinear dynamic analysis to estimate the seismic performance of the bridge. Furthermore, fragility curves are developed for the bridge to estimate the damage state for specific seismicity. The study shows that the bridge is vulnerable to Zone IV seismicity and needs some retrofitting in specific locations such as the pier–abutment joints.
The Effects of Animistic Thinking, Animistic Cues, and Superstitions on Brand Responses on Social Media
Authors: Karpinska-Krakowiak Malgorzata , Eisend Martin
Published: May 2021

Although marketers have been using various message tactics to breathe life into their brands, the concepts of animism and animistic cues, particularly in social media marketing, have received little theoretical and empirical attention. Therefore, we conducted two studies to uncover what drives animistic thinking on social media, how animism is linked to anthropomorphism, how animism can benefit brands online, and what the boundary conditions for this phenomenon are. The findings demonstrate that animistic (vs. non-animistic) cues elicit animistic thinking, which leads to more favorable brand evaluations. This effect is moderated by superstitious beliefs. The results provide new knowledge for both marketing researchers and practitioners, revealing that it is easier to activate animism than anthropomorphism on social media and that such activation can be done via easily devisable cues (such as simple movement), particularly when addressing highly superstitious consumers.
Samuel Beckett and Cultural Nationalism
Authors: Weller Shane
Published: May 2021

Drawing on evidence from his published works, manuscripts, and correspondence, Samuel Beckett and Cultural Nationalism explores Beckett's engagement with the theme of cultural nationalism throughout his writing life, revealing the various ways in which he sought to challenge culturally nationalist conceptions of art and literature, while never embracing a cosmopolitan approach. The Element shows how, in his pre-Second World War writings, Beckett sought openly to mock Irish nationalist ideas of culture and language, but that, in so doing, he failed to avoid what he himself described as a 'clot of prejudices'. In his post-war works in French and English, however, following time spent in Nazi Germany in 1936-7 as well as in the French Resistance during the Second World War, Beckett began to take a new approach to ideas of national-cultural affiliation, at the heart of which was a conception of the human as a citizen of nowhere.

Published: May 2021

The Inquisitions post mortem (IPMs) are a truly wonderful source for many different aspects of late medieval countryside and rural life. They have recently been made digitally accessible and interrogatable by the Mapping the Medieval Countryside project, and the first fruits of these developments are presented here. The chapters examine IPMs in connection with the landscape and topography of England, in particular markets and fairs and mills; and consider the utility of proofs of age for everyday life on such topics as the Church, retaining, and the wine trade. Michael Hicks is Emeritus Professor of Medieval History at the University of Winchester. Contributors: Katie A. Clarke, William S.

Published: May 2021

Background

Caregiver mental health is linked to early childhood development, yet more robust evidence of community-based interventions to prevent maternal depression and optimize socio-emotional development of young children is needed. Objectives of this cluster-randomized controlled trial (cRCT), based in Northern Ghana, are to assess the impact of the lay counselor-delivered, group-based Integrated Mothers and Babies Course and Early Childhood Development (iMBC/ECD) program on (1) the mental health of mothers of children under age 2; and (2) the socio-emotional development of their children.

Methods

This cRCT randomized 32 women's groups – 16 received iMBC/ECD content (intervention) and 16 received general health education content (control). Surveys were administered at baseline, immediate post-intervention, and 8-month post-intervention. The primary outcome was maternal depression [Patient Health Questionnaire (PHQ-9)], and the secondary outcome was child's socio-emotional development [Ages and Stages Questionnaire: Social Emotional (ASQ:SE-2)]. Qualitative interviews with 33 stakeholders were also conducted.

Results

In total, 374 participants were enrolled at baseline while pregnant with the index child, 19% endorsing moderate/severe depression. Of these, 266 (71.1%) completed the 8-month post-intervention survey (~19 months post-baseline). There were no significant effects of iMBC/ECD on PHQ-9 and ASQ:SE-2 scores. However, results favored the intervention arm in most cases. iMBC participants were highly satisfied with the program but qualitative feedback from stakeholders indicated some implementation challenges.

Conclusions

This real-world evaluation had null findings; however, post-intervention depression levels were very low in both arms (3%). Future research should examine the potential impact of women's groups on postpartum mental health more broadly with varying content.
Incidence and burden of Staphylococcus aureus infection after orthopedic surgeries
Authors: Dreyfus Jill G. , Yu Holly , Begier Elizabeth , Gayle Julie , Olsen Margaret A.
Published: May 2021

Objective:

To assess the 180-day incidence of Staphylococcus aureus infections following orthopedic surgeries using microbiology cultures.

Design:

Retrospective observational epidemiology study.

Setting:

National administrative hospital database.

Patients:

Adult patients with an elective admission undergoing orthopedic surgeries in the inpatient and hospital-based outpatient settings discharged between July 1, 2010, and June 30, 2015.

Methods:

Patients were identified from 181 hospitals reporting microbiology results to the Premier Healthcare Database. Orthopedic surgeries were defined using International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) procedure and current procedural terminology (CPT) codes. Microbiology cultures and ICD-9/10 diagnosis codes identified surgical site infections (SSIs), bloodstream infections (BSIs), and other infections associated postoperatively (eg, respiratory and urinary tract infections).

Results:

Among 359,268 inpatient orthopedic surgical encounters, the S. aureus infection incidence was 1.13%: SSI, 0.68%; BSI, 0.28%; and other types, 0.17%. Among 292,011 outpatient encounters, the S. aureus incidence was 0.78%: SSI, 0.55%; BSI, 0.12%; and other types, 0.11%. Methicillin-resistant S. aureus (MRSA) infections accounted for 46% and 44% in the respective settings. Plastic/hand-limb reattachment and amputation had the highest overall S. aureus incidence in both settings. S. aureus was the most commonly isolated microorganism among culture-confirmed SSIs (48.0%) and BSIs (35.0%), followed by other Enterobacteriaceae (14.0%) for SSIs and Escherichia spp (12.5%) for BSIs.

Conclusions:

These findings suggest that S. aureus infections continue to be an important contributor to the burden of postoperative infections after inpatient and outpatient orthopedic procedures.
Psychological anthropology and medical anthropology: a brief history of ideas and concepts
Authors: Sheehan Cormac
Published: May 2021

This paper sets out to briefly explore the definitions of two interrelated subfields of cultural anthropology; psychological anthropology and medical anthropology. This exploration will argue that culture and the individual are intimately intertwined. The theoretical evolution within psychological anthropology will be presented, from the bio-moral classifications of the ‘primitive’ to modern ‘experience near’ ethnographies, and fluid understanding of personhood. Theoretical and methodological approaches to mental health will be discussed briefly. Finally, the conclusion will ask the question: what is the future for medical and psychological anthropology?
Eolian sedimentation in central European Auel dry maar from 60 to 13 ka
Authors: Fuhrmann Florian , Seelos Klemens , Sirocko Frank
Published: May 2021

The climate in central Europe during the last 60 ka is characterized by rapid temperature and moisture changes and strong cold periods (Heinrich events). All these variations are preserved in sediments of marine and also some terrestrial archives. Here we present a continuous, terrestrial sediment record with almost all Greenland stadials and Heinrich events between 60 and 13 ka visible from carbonate roundness of the Eifel Laminated Sediment Archive Dust Stack-20 and CaCO3 data for central Europe. The carbonate roundness data show almost all stadials between 60 and 13 ka. CaCO3 data show a general transport system change with the beginning of Heinrich event 3. Since there are no carbonates west of the Auel Maar, we conclude that the eolian-transported grains were not transported by westerly but easterly winds. These postulated easterly winds during the last glacial maximum are supported by similar findings of previous works.
What is truth? A Johannine theological epistemology
Authors: Andrew Matthew
Published: May 2021

This essay begins with Pilate's question – ‘What is truth?’ – and notes the way it sets us up to long for a second-person experience of Jesus. I argue that this longing is met in the literary function of the Beloved Disciple, which prepares us for our own second-person encounter with Jesus. This raises some puzzles: can the Spirit convey to us a second-person encounter with Jesus? How do we know we have been so addressed by Jesus? Given John's above/below dualism, what does such an encounter mean for our theological language? I answer these questions in turn.
Technology assessment framework for precision health applications
Authors: Hussain M. Sazzad , Silvera-Tawil David , Farr-Wharton Geremy
Published: May 2021

Objective

Established and emerging technologies—such as wearable sensors, smartphones, mobile apps, and artificial intelligence—are shaping positive healthcare models and patient outcomes. These technologies have the potential to become precision health (PH) innovations. However, not all innovations meet regulatory standards or have the required scientific evidence to be used for health applications. In response, an assessment framework was developed to facilitate and standardize the assessment of innovations deemed suitable for PH.

Methods

A scoping literature review undertaken through PubMed and Google Scholar identified approximately 100 relevant articles. These were then shortlisted (n = 12) to those that included specific metrics, criteria, or frameworks for assessing technologies that could be applied to the PH context.

Results

The proposed framework identified nine core criteria with subcriteria and grouped them into four categories for assessment: technical, clinical, human factors, and implementation. Guiding statements with response options and recommendations were used as metrics against each criterion.

Conclusion

The proposed framework supports health services, health technology innovators, and researchers in leveraging current and emerging technologies for PH innovations. It covers a comprehensive set of criteria as part of the assessment process of these technologies.

Published: May 2021

The rapid transmissibility of the severe acute respiratory syndrome-coronavirus-2 causing coronavirus disease-2019, requires timely dissemination of information and public health responses, with all 47 countries of the WHO African Region simultaneously facing significant risk, in contrast to the usual highly localised infectious disease outbreaks. This demanded a different approach to information management and an adaptive information strategy was implemented, focusing on data collection and management, reporting and analysis at the national and regional levels. This approach used frugal innovation, building on tools and technologies that are commonly used, and well understood; as well as developing simple, practical, highly functional and agile solutions that could be rapidly and remotely implemented, and flexible enough to be recalibrated and adapted as required. While the approach was successful in its aim of allowing the WHO Regional Office for Africa (WHO AFRO) to gather surveillance and epidemiological data, several challenges were encountered that affected timeliness and quality of data captured and reported by the member states, showing that strengthening data systems and digital capacity, and encouraging openness and data sharing are an important component of health system strengthening.
Serum micronutrient status, sleep quality and neurobehavioural function among early adolescents
Authors: Ji Xiaopeng , Compher Charlene W , Irving Sharon Y , Kim Jinyoung , Dinges David F , Liu Jianghong
Published: May 2021

Objective:

To examine associations between serum micronutrients and neurobehavioural function and the mediating role of sleep quality in early adolescents.

Design:

In this cross-sectional study, peripheral blood samples were analysed for Fe and Zn levels. The Pittsburgh Sleep Quality Index and Penn Computerized Neurocognitive Battery were used to assess sleep quality and neurobehavioural function, respectively. The logistic/linear regressions and generalised structural equation modelling were performed to estimate the associations.

Setting:

Jintan, China

Participants:

In total, 226 adolescents (106 females) from the Jintan Child Cohort study.

Results:

Adolescents with low Fe (<75 μg/dl) (OR = 1·29,P= 0·04) and low Zn (<70 μg/dl) (OR = 1·58,P< 0·001) were associated with increased odds for poor sleep quality. Adolescents with low Fe and Zn were associated with fast (Fe:β= –1353·71,P= 0·002, Zn:β= –2262·01,P= 0·02) but less-accurate (Fe:β= –0·97,P= 0·04; Zn:β= –1·76,P= 0·04) performance on non-verbal reasoning task and poor sleep quality partially mediated the associations between low Fe/Zn and non-verbal reasoning (P< 0·05). Additionally, low Fe was associated with a slower reaction on spatial processing task (β= 276·94,P= 0·04), and low Zn was associated with fast (β= –1781·83,P= 0·03), but error-prone performance (β= –1·79,P= 0·04) on spatial processing ability and slower reaction speed (β= 12·82,P= 0·03) on the attention task. We observed similar trends using a cut-off point of 75 μg/dl for low serum Zn, except for the association with attention task speed (P> 0·05).

Conclusion:

Fe and Zn deficiencies may possibly be associated with poor sleep and neurobehavioural function among early adolescents. Poor sleep may partially mediate the relationship between micronutrients and neurobehavioural function.
How Conscientiousness and Neuroticism Affect Academic Procrastination
Authors: Bäulke Lisa , Daumiller Martin , Dresel Markus
Published: May 2021

Abstract. We examined students’ procrastinatory behavior in a specific higher-education learning situation in relation to conscientiousness and neuroticism as well as motivational regulation. We hypothesized that conscientiousness would be associated with low levels and favorable trajectories of academic procrastinatory behavior, and neuroticism would be associated with high levels and unfavorable trajectories of procrastinatory behavior. Furthermore, we examined whether motivational regulation mediates these effects. To answer our research questions, we used data from a diary study that spanned a period of 28 days with a total of 3,121 single measurements of 128 university students (mean age = 21.7 years; SD = 2.2; 53 % female). The results of conditional growth curve models indicated that levels of procrastinatory behavior were negatively linked to conscientiousness and positively linked to neuroticism. Motivational regulation mediated the relation between conscientiousness and procrastinatory behavior. No effects on the trajectories of procrastinatory behavior were found. Our findings provide insights into procrastinatory behavior in a specific learning situation and emphasize the functional effects of motivational regulation on academic procrastination.
Measurement Invariance of the SOC-13 Sense of Coherence Scale Across	Gender and Age Groups
Authors: Grevenstein Dennis , Bluemke Matthias
Published: May 2021

Abstract. Sense of coherence (SOC) describes an individual’s ability to deal with life challenges (manageability), comprehend the environment (comprehensibility), and perceive life and its challenges as meaningful (meaningfulness). We examine measurement invariance (MI) of the SOC-13 scale across gender and age groups in a matched sample of N = 1,816 (50% females; age range 16–83 years). A two-factor model, with a common factor for manageability/comprehensibility items and a second factor for meaningfulness items, best represented the SOC-13 in all groups. Full metric, partial scalar, and full strict invariance held across gender groups. Across age groups, full metric, partial scalar, and partial strict invariance could be established. We conclude that SOC-13 is a reliable and valid measure. Measurement is comparable across gender and age.

Authors: Metin Ahmet , Çetinkaya Ali , Erbiçer Eyüp Sabır
Published: May 2021

Abstract. Background: The COVID-19 pandemic has penetrated almost all countries and has affected people in many areas. The COVID-19 pandemic also has affected the mental health of the community. Aims: The purpose of this study is to investigate the individuals’ perceptions of subjective well-being (SWB) and resilience (R) during the pandemic. Method: A total of 643 people, 351 women and 292 men, who are not diagnosed with COVID-19, have voluntarily participated in the study. The data were collected online due to social restrictions. Also, their pre-pandemic SWB and R levels were evaluated based on their statements taken during the pandemic since the pandemic was not foreseen at this time. Results: A significant decrease was observed in participants’ SWB and R levels during the pandemic. Besides, significant differences were observed in R levels according to gender and age; on the other hand, no difference was observed according to the participants’ residence type, city type, education level, and job status. Regarding SWB level, significant differences were observed according to gender, age, and job status; no difference was observed according to residence type, city type, and education level. Limitations: Participants’ subjective well-being and resilience data could not be collected before the pandemic due to the unpredictable and fast spread of the COVID-19 pandemic. When individuals compare the current pandemic period with their past (before the pandemic), they may perceive their resilience and subjective well-being levels as decreased. Conclusion: The pandemic affects the subjective well-being and resilience of individuals negatively.
Adolescents at a Distance
Authors: Cavicchiolo Elisa , Manganelli Sara , Girelli Laura , Cozzolino Mauro , Lucidi Fabio , Alivernini Fabio
Published: May 2021

Abstract. Background: In many countries, physical distancing is seen as one of the crucial preventive measures for limiting the COVID-19 pandemic. However, it is likely to be very difficult to ensure that adolescents keep apart from one another since peer interactions are extremely significant for them. Aims: We examined the utility of the Theory of Planned Behavior enhanced with a construct of the Protection Motivation Theory for predicting physical distancing behavior among adolescents during the period following the national lockdown imposed in Italy to tackle the pandemic. Method: Measures of attitude, subjective norm, perceptions of behavioral control, perceptions of threat regarding personal health and the health of loved ones, and intention were administered to the participants ( N = 363) at baseline. Measures of physical distancing behavior were then administered 3 weeks later ( N = 350). Results: The tested structural equation model accounted for 77% of variance in intention and 25% of variance in behavior. Perceived behavioral control and attitude were important predictors of intention and behavior, while the data did not support the hypothesized impact of perceptions of threat. Limitation: Due to the observational nature of the data caution should be taken in drawing causal inferences. Conclusion: The results suggest that programs for increasing physical distancing behavior in adolescents by concentrating exclusively on risks to their health or that of their loved ones might prove to be ineffective. Instead, it seems likely that prevention campaigns targeting adolescents will be more successful if they focus on perceived behavioral control and attitude.
Comparison of Lightning Detection Between the FY‐4A Lightning Mapping Imager and the ISS Lightning Imaging Sensor
Authors: Ni Xiang , Hui Wen , Zhang Qinghong , Huang Fuxiang , Liu Chuntao
Published: May 2021

The Lightning Mapping Imager (LMI) onboard Fengyun‐4A (FY‐4A) is the first Chinese lightning detection sensor in geostationary orbit. This study presents the lightning characteristics observed by the FY‐4A LMI in its first year, and then observations from the Lightning Imaging Sensor (LIS) onboard the International Space Station (ISS) are used to validate the performance of the LMI sensor. LMI lightning events are defined by the pixel's luminosity exceeding the threshold radiance. During the first year of operation, LMI events revealed a reasonable geographical distribution. The diurnal cycles of LMI event/background/threshold radiance are in general agreement with the later afternoon peaks in previous findings. However, the LMI events that occurred around the LIS flash time and in the LMI observation field‐of‐view show a slightly delayed peak at around 1900 LST. This peak can be shifted closer to LIS's results after removing LMI events with event radiance lower than 300 , suggesting that a larger threshold radiance value is needed to qualify some of these LMI events. Finally, LIS lightning groups were matched with LMI lightning events using different temporal and spatial collocation criteria. The detection efficiency is defined by the fraction of LIS groups detected by LMI to assess LMI's performance. The LMI detection efficiency relative to LIS was found to be regionally dependent and lower in the daytime than at nighttime. These results contribute to applications of LMI lightning observations in storm research and provide suggestions for further algorithm improvement.

We present multi‐point observations of foreshock bubbles (FBs) for comparison with the predictions of hybrid simulations. The four Magnetospheric Multiscale (MMS) spacecraft observed a series of discontinuities in the region upstream from the bow shock on December 18, 2017. Two solar wind discontinuities were associated with fully developed FBs with core regions exhibiting greatly decelerated and deflected antisunward flows, significant increases in temperature, and depressed plasma densities and magnetic field strengths. A single shock lies upstream (sunward) from each of the two bubbles. The connection to the foreshock before and/or after the discontinuities can play an important role in the foreshock transient formation. We present the predictions of a 2.5‐D global hybrid simulation for the presence of the FBs for two different interplanetary magnetic field (IMF) cone angles (66° and 25°). The topology of the simulated FB is nearly hemispherical for small angles, but becomes linear for large angles. We show that the characteristics of the two simulated FBs for the two different discontinuity normals and IMF cone angles are in good agreement with the observational results.

Anisotropy of magnetic susceptibility (AMS) and anisotropy of magnetic remanence (AARM and AIRM) are efficient and versatile techniques to indirectly determine rock fabrics. Yet, deciphering the source of a magnetic fabric remains a crucial and challenging step, notably in the presence of ferrimagnetic phases. Here we use X‐ray micro‐computed tomography to directly compare mineral shape‐preferred orientation and spatial distribution fabrics to AMS, AARM and AIRM fabrics from five hypabyssal trachyandesite samples. Magnetite grains in the trachyandesite are euhedral with a mean aspect ratio of 1.44 (0.24 s.d., long/short axis), and >50% of the magnetite grains occur in clusters, and they are therefore prone to interact magnetically. Amphibole grains are prolate with magnetite in breakdown rims. We identified three components of the petrofabric that influence the AMS of the analyzed samples: The magnetite and the amphibole shape fabrics and the magnetite distribution anisotropy. Depending on their relative strength, orientation and shape, these three components interfere either constructively or destructively to produce the AMS fabric. If the three components are coaxial, the result is a relatively strongly anisotropic AMS fabric (P' = 1.079). If shape fabrics and/or magnetite distribution anisotropy are non‐coaxial, the resulting AMS is weakly anisotropic (P' = 1.012). This study thus reports quantitative petrofabric data that show the effect of magnetite distribution anisotropy on magnetic fabrics in igneous rocks, which has so far only been predicted by experimental and theoretical models. Our results have first‐order implications for the interpretation of petrofabrics using magnetic methods.

High speed spectra (between ∼380 nm and ∼800 nm) of meter‐long lightning‐like discharges recorded at 672,000 fps and 1,400,000 fps (with 1.488 and 0.714 μs time resolutions and 160 ns exposure time) show optical emissions of neutral hydrogen, singly ionized nitrogen, oxygen, and doubly ionized nitrogen which are similar to those found in natural lightning optical emissions. The spectra recorded in the near ultraviolet‐blue range (380–450 nm) and visible‐near infrared (475–793 nm) exhibited features of optical emissions corresponding to several molecular species (and emission bands) like cyanide radical (CN) (Violet bands), N2 (Second Positive System), N2+ (first negative system), C2 (Swan band) and CO (Quintet and Ångström bands). Molecular species can be formed at regions of the lightning‐like channel where the gas temperature would be milder and/or in the corona sheath surrounding the heated channel. We have quantified and compared electron densities and temperatures derived from different sets of neutral and ion line emissions and have found different sensitivities depending on the lines used. Temperatures derived from ion emissions are higher and change faster than those derived from neutral emissions.
Three-dimensional reconstruction of systematic histological sections: application to observations on palatal shelf elevation

Normal mammalian secondary palate development undergoes a series of processes, including palatal shelf (PS) growth, elevation, adhesion and fusion, and palatal bone formation. It has been estimated that more than 90% of isolated cleft palate is caused by defects associated with the elevation process. However, because of the rapidly completed elevation process, the entire process of elevation will never be easy to clarify. In this article, we present a novel method for three-dimensional (3D) reconstruction of thick tissue blocks from two-dimensional (2D) histological sections. We established multiplanar sections of the palate and tongue in coronal and sagittal directions, and further performed 3D reconstruction to observe the morphological interaction and connection between the two components prior to and during elevation. The method completes an imaging system for simultaneous morphological analysis of thick tissue samples using both synthetic and real data. The new method will provide a comprehensive picture of reorientation morphology and gene expression pattern during the palatal elevation process.

The combination of electrophysiology and optogenetics enables the exploration of how the brain operates down to a single neuron and its network activity. Neural probes are in vivo invasive devices that integrate sensors and stimulation sites to record and manipulate neuronal activity with high spatiotemporal resolution. State-of-the-art probes are limited by tradeoffs involving their lateral dimension, number of sensors, and ability to access independent stimulation sites. Here, we realize a highly scalable probe that features three-dimensional integration of small-footprint arrays of sensors and nanophotonic circuits to scale the density of sensors per cross-section by one order of magnitude with respect to state-of-the-art devices. For the first time, we overcome the spatial limit of the nanophotonic circuit by coupling only one waveguide to numerous optical ring resonators as passive nanophotonic switches. With this strategy, we achieve accurate on-demand light localization while avoiding spatially demanding bundles of waveguides and demonstrate the feasibility with a proof-of-concept device and its scalability towards high-resolution and low-damage neural optoelectrodes.

Anxiety-like behavior of rodents is frequently accompanied by reduced exploration. Here, we identify dissociable components of anxiety, fear, and exploratory drive of sated and foraging mice. With the help of behavioral assays, including the open field task, elevated plus maze, dark–light transition task, and beetle mania task, we demonstrate a general increase in exploration by food restriction. Food-restricted mice bred for high anxiety behavior (HAB) showed ameliorated anxiety- but not fear-related behavior. By means of principal component analysis, we identified three independent components, which resemble the behavioral dimensions proposed by Gray’s Reinforcement Sensitivity Theory (approach behavior, avoidance behavior, and decision making). Taken together, we demonstrate anxiolytic consequences of food restriction in a mouse model of anxiety disorders that can be dissociated from a general increase in foraging behavior.
