AbstractHistoric declines in young people’s mental health began to emerge before the COVID-19 pandemic. In the face of this youth mental health crisis, the pandemic constituted a naturalistic stressor paradigm that came with the potential to uncover new knowledge for the science of risk and resilience. Surprisingly, approximately 19-35% of people reported better well-being in the first few months of the COVID-19 pandemic than before. Therefore, in May and September 2020, we asked N=517 young adults from a cohort study to describe the best and the worst aspects of their pandemic lives (N=1,462 descriptions). Inductive thematic analysis revealed that the best aspects included the deceleration of life and a greater abundance of free time, which was used for hobbies, healthy activities, strengthening relationships, and for personal growth and building resilience skills. Positive aspects also included a reduction in educational pressures and work load and temporary relief from climate change concerns. The worst aspects included disruptions and changes to daily life; social distancing and restrictions of freedoms; negative emotions that arose in the pandemic situation, including uncertainty about the future; and the growing polarization of society. Science that aims to reverse the youth mental health crisis must pay increased attention to sources of young people’s distress that are not commonly measured (e.g., their educational, work, and time pressures; their fears and uncertainties about their personal, society’s, and the global future), and also to previously untapped sources of well-being – including those that young people identified for themselves while facing the COVID-19 pandemic.

Published: April 2023

AbstractThe substitution of traditional materials with lightweight materials in vehicle structures requires the development of new joining techniques which are capable of joining un-weldable alloys as well as dissimilar materials. Although conventional joining techniques such as fusion welding, adhesive bonding and mechanical fastening have matured in recent decades, their use for some of the above applications is limited. In this paper, recently developed joining techniques based on plastic deformation are presented and discussed. These techniques are divided into two categories, those based on mechanical interlocking and those based on metallurgical bonding. The first category covers clinching, self-pierce riveting and some innovative joining methods, and the second category covers friction stir welding and its variants. The focus of this study is on process development, process control and monitoring, process modelling, and joint characterization techniques. Finally, the two categories are compared, and their potential is discussed.

AbstractDuring the second half of the 20th century, the Antarctic Peninsula region has undergone a long and sustained warming period, followed by a shorter but also sustained cooling period, and then a very recent return to warming conditions. All of these have profoundly impacted the glaciers peripheral to the Antarctic Peninsula. This paper focuses on the analysis of the surface mass balance monitoring of such glaciers by the glaciological method, complemented by the analysis of mass-balance estimates by geodetic methods, as well as frontal ablation estimates. We aim to summarize the current knowledge and outline the main challenges faced by investigating the mass balance of such peripheral glaciers and their current contribution to sea-level rise.

Abstract
To assess the determinants of hunger among food pantry users, the present study used a cross-sectional survey that included a modified Household Hunger Scale to quantify hunger. Mixed-effects logistic regression models were used to assess the relationship between hunger categories and various household socio-demographic and economic characteristics, such as age, race, household size, marital status and experience of any economic hardship. The survey was administered to food pantry users from June 2018 to August 2018 at various food pantries across Eastern Massachusetts with 611 food pantry users completing the questionnaire at any of the 10 food pantry sites. One-fifth (20⋅13 %) of food pantry users experienced moderate hunger and 19⋅14 % experienced severe hunger. Food pantry users who were single, divorced or separated; had less than a high school education; working part-time, unemployed or retired; or, who earned incomes less than $1000 per month were most likely to experience severe or moderate hunger. Pantry users who experienced any economic hardship had 4⋅78 the adjusted odds of severe hunger (95 % CI 2⋅49, 9⋅19), which was much larger than the odds of moderate hunger (AOR 1⋅95; 95 % CI 1⋅10, 3⋅48). Younger age and participation in WIC (AOR 0⋅20; 95 % CI 0⋅05–0⋅78) and SNAP (AOR 0⋅53; 95 % CI 0⋅32–0⋅88) were protective against severe hunger. The present study illustrates factors affecting hunger in food pantry users, which can help inform public health programmes and policies for people in need of additional resources. This is essential particularly in times of increasing economic hardships recently exacerbated by the COVID-19 pandemic.
The Tradeoff Between Private Equity Sponsorship, Board Centrality, and Experience as Credible Signals for IPO Performance
Authors: Kirschbaum Charles , Rossoni Luciano , Minardi Andrea , da Silva Emília Borges 
Published: April 2023

ABSTRACTPrivate equity funds implement various management and governance practices in firms they endorse, signaling higher quality of sponsored IPOs (Initial Public Offer). However, the participation of such PE funds comes at a cost for newcomer firms, as they may lose both autonomy and future post-IPO earnings. If they do not choose to signal quality through PE funds, the IPO literature points to the validity of other mechanisms, such as the experience and centrality of the board of directors. We theorize and test the effect of the tradeoff between private equity sponsorship and board centrality and experience on IPO performance. We analyzed the effects of signaling on long-term performance through the one-year cumulative abnormal return in Brazilian IPOs issued between 2004 and 2013. Our results indicate that private equity sponsorship is the most effective signal, completely overtaking the relevance of board centrality and experience to explain IPO performance. However, these latter board characteristics significantly affected the performance of non-private equity-backed IPOs. Between PE-backed companies, there is a reverse effect of the board centrality on the IPO's performance and a substitution effect of the board's previous experience with IPO processes.
The Roles of Supply Networks and Board Interlocks in Firms’ Technological Entry and Exit: Evidence from the Chinese Automotive Industry
Authors: Aalbers Rick , Ma Rongkang 
Published: April 2023

ABSTRACTIn this research, we explore how supply networks and board interlocks – as distinct, yet parallel interorganizational networks – jointly influence firms’ entry into new technology domains and exit from old technology domains. Drawing from the perspectives of social networks and organizational learning we highlight the relevance of the interdependency between these networks for a firm's technological entry and exit decisions. We argue that a firm that maintains a large number of supplier ties is more likely to enter new technology domains and exit from old technology domains instead. We further find empirical evidence that the degree centrality of a firm in its board interlock network strengthens these effects. Our theoretical arguments are supported through stochastic actor-based modeling analysis for the longitudinal and multilevel networks of 86 firms active in the Chinese automotive during 2011–2015. These findings inform the literature on interorganizational network dynamics as we insert relational pluralism to examine the complexities of organizational relationships as antecedents to a firms’ technological entry and exit. Finally, we imagine the implications of our analysis for management as they shed light on how multiple interorganizational relationships affect firms’ decisions on new technology entry and old technology exit.
Too Much of a Good Thing: Downsides of a Large Social Network and Moderating Effects of Political Skill
Authors: Chen Yi , Boh Wai Fong , Wong Sze-Sze , Shao Jun 
Published: April 2023

AbstractExisting research examining the curvilinear relationship between network centrality and performance tends to focus on the information recipients’ perspective. Focusing on the information providers’ perspective, our study draws upon social exchange theory to demonstrate that the advice-giving centrality-performance relationship for information providers has an inverse U-shape due to decreasing benefits and increasing costs of maintaining more advice-giving ties. We further show that increasing advice-giving centrality increases the likelihood that individuals would become a hindrance to coworkers, as they become bottlenecks impeding efficient workflow. However, our study demonstrates that political skill enables them to overcome the interpersonal challenges associated with high advice-giving centrality. Specifically, individuals with high political skills can better convert advice-giving ties to resources that could assist their cooperation with coworkers, reducing the hindrance they impose. Overall, we provide insights into the trade-off between the benefits and costs of advice-giving ties from a social exchange perspective and examine political skill as an important mitigator of the downsides of large advice-giving networks – a key area that has been hitherto largely unexplored.

Abstract
The quenching of cluster satellite galaxies is inextricably linked to the suppression of their cold interstellar medium (ISM) by environmental mechanisms. While the removal of neutral atomic hydrogen (H i) at large radii is well studied, how the environment impacts the remaining gas in the centres of galaxies, which are dominated by molecular gas, is less clear. Using new observations from the Virgo Environment traced in CO survey (VERTICO) and archival H i data, we study the H i and molecular gas within the optical discs of Virgo cluster galaxies on 1.2-kpc scales with spatially resolved scaling relations between stellar (

$\Sigma_{\star}$

), H i (

$\Sigma_{\text{H}\,{\small\text{I}}}$

), and molecular gas (

$\Sigma_{\text{mol}}$

) surface densities. Adopting H i deficiency as a measure of environmental impact, we find evidence that, in addition to removing the H i at large radii, the cluster processes also lower the average

$\Sigma_{\text{H}\,{\small\text{I}}}$

of the remaining gas even in the central

$1.2\,$

kpc. The impact on molecular gas is comparatively weaker than on the H i, and we show that the lower

$\Sigma_{\text{mol}}$

gas is removed first. In the most H i-deficient galaxies, however, we find evidence that environmental processes reduce the typical

$\Sigma_{\text{mol}}$

of the remaining gas by nearly a factor of 3. We find no evidence for environment-driven elevation of

$\Sigma_{\text{H}\,{\small\text{I}}}$

or

$\Sigma_{\text{mol}}$

in H i-deficient galaxies. Using the ratio of

$\Sigma_{\text{mol}}$

-to-

$\Sigma_{\text{H}\,{\small\text{I}}}$

in individual regions, we show that changes in the ISM physical conditions, estimated using the total gas surface density and midplane hydrostatic pressure, cannot explain the observed reduction in molecular gas content. Instead, we suggest that direct stripping of the molecular gas is required to explain our results.
Potential field-based dual heuristic programming for path-following and obstacle avoidance of wheeled mobile robots
Authors: Peng Yaoqian , Zhang Xinglong , Xie Haibin , Xu Xin 
Published: April 2023

AbstractPath-following control of wheeled mobile robots has been a crucial research topic in robotic control theory and applications. In path-following control with obstacles, the path-following control and collision avoidance goals might be conflicting, making it challenging to obtain near-optimal solutions for path-following control and obstacle avoidance with low tracking error and input energy consumption. To address this problem, we propose a potential field-based dual heuristic programming (P-DHP) algorithm with an actor–critic (AC) structure for path-following control of mobile robots with obstacle avoidance. In the proposed P-DHP, the path-following control and collision avoidance problems are decoupled into two ones to resolve the control conflict. Firstly, a neural network-based AC is constructed to approximate the near-optimal path-following control policy in a no-obstacle environment. Then, with the trained path-following control policy fixed, a potential field-based control policy structure is constructed by another AC network to generate opposite control forces as the robot moves toward the obstacle, which can guarantee the robot’s control safety and reduce the tracking error and input energy consumption in obstacle avoidance. The simulated and experimental results show that P-DHP can realize near-optimal path-following control with the satisfaction of safety constraints and outperforms state-of-the-art approaches in control performance.

Published: April 2023

AbstractThe Vancouver Obsessional Compulsive Inventory–Mental Contamination scale (VOCI-MC) and the Contamination Thought–Action Fusion scale (CTAF) are two self-report instruments that assess symptoms of mental contamination and fusion between thoughts, and feelings and behaviours associated with contamination, respectively. The aim of this study was to investigate the psychometric properties of the French version of these two scales in non-clinical and clinical samples. We included 79 participants diagnosed with obsessive-compulsive disorder (OCD), 31 diagnosed with anxiety disorders, who were recruited from the University Department of Adult Psychiatry in Montpellier, and 320 non-clinical participants recruited from the general population. Psychometric properties of the French VOCI-MC and CTAF were investigated. Results showed that the French versions of the VOCI-MC and the CTAF had high internal consistency, good convergent and divergent validity, as well as good temporal stability. Exploratory and confirmatory factor analyses showed a one-factor structure for the two scales in both non-clinical and OCD samples. Adequate discriminative validity was established by comparing OCD patients with contamination-related symptoms and OCD patients who did not report contamination-related symptoms. The French VOCI-MC and CTAF are valid and appropriate tools for measuring mental contamination in both clinical and research contexts.
Impact of culturally tailored shared medical appointments on diabetes self-care ability and knowledge in African Americans
Authors: Reddick Adrienne L. , Gray Deborah C. 
Published: April 2023

Abstract

Background:
Type 2 diabetes mellitus (T2DM) continues to disproportionately affect African Americans, significantly impacting morbidity and mortality. Research suggests that addressing barriers that stem from socioeconomic circumstances, systemic inequalities, biological factors, and cultural factors may positively influence biometric indicators of health and diabetes control.

Objective:
The aim of this study was to evaluate a diabetes shared medical appointment (SMA) model program that has been culturally tailored to address the unique social determinants of health barriers faced by an inner city African American population in Norfolk, Virginia.

Methods:
A pilot study using a within-group pretest–posttest design was conducted. Information was collected from self-report surveys that included the Modified Michigan Diabetes Knowledge Test, the Diabetes Self-Efficacy Scale, and researcher generated surveys before and after a single-session three-hour SMA program.

Key Results:
The program increased perceived diabetes self-care confidence and perceived overall diabetes knowledge levels. Increases in knowledge scores were seen but not statistically significant. Participants reported high levels of satisfaction with the program model.

Discussion:
Findings indicate that this model is an effective and engaging method of improving self-care ability and diabetes disease management knowledge among African Americans. Addressing unique circumstances and barriers experienced by this population may be more effective than usual traditional care approaches.
‘I’m a bit of a champion for it actually’: qualitative insights into practitioner-supported self-collection cervical screening among early adopting Victorian practitioners in Australia

Published: April 2023

Abstract

Background:
Self-collection for cervical screening has been available in the Australian National Cervical Screening Program since 2017 and is now available to all people as an option for cervical screening through a practitioner-supported model. Documenting early adopting practitioner experiences with self-collection as a mechanism to engage people in cervical screening is crucial to informing its continuing roll-out and implementation in other health systems.

Aim:
This study aimed to describe the experiences of practitioners in Victoria, Australia, who used human papillomavirus (HPV)-based self-collection cervical screening during the first 17 months of its availability.

Methods:
Interviews (n = 18) with practitioners from Victoria, who offered self-collection to their patients between December 2017 and April 2019, analysed using template analysis.

Findings:
Practitioners were overwhelmingly supportive of self-collection cervical screening because it was acceptable to their patients and addressed patients’ barriers to screening. Practitioners perceived that knowledge and awareness of self-collection were variable among the primary care workforce, with some viewing self-collection to be inferior to clinician-collected screening. Practitioners championed self-collection at an individual level, with the extent of practice-level implementation depending on resourcing. Concerns regarding supporting the follow-up of self-collected HPV positive patients were noted. Other practical barriers included gaining timely, accurate screening histories from the National Cancer Screening Register to assess eligibility. Practitioners’ role surrounded facilitating the choice between screening tests through a patient-centred approach.
Modern China's financial obligations and strategies, 1901–1925: the depreciation of tael, the Austrian loans and the gold franc
Authors: Chang Chihyun , Kao Chiu-Ya 
Published: April 2023

AbstractThe financial burden of the Boxer Indemnity forced the Chinese government to change its behaviours since 1901. This article re-examines the position that the decision to honour indeminity obligations enabled the Chinese state to maintain peaceful relations with western powers during the first quarter of the twentiety century. The 1901 edict affirming that China would re-examine its capacity to satisfy its international commitments. Before this edict, China had selectively followed its Sino-foreign treaties, but thereafter, China completely assumed all of her financial obligations to foreign creditors. These changes in behaviour helped China restore its deteriorated foreign relations and were followed by Provisional Executive Duan Qirui until 1925. These changes can be illustrated by three cases, namely the depreciation of tael, the Austrian loans, and the gold franc. The cases were highly international as the first concerned eleven foreign creditors, the second concerned two, and the third concerned three. From 1901–1925, foreign powers also provided China with reciprocal favours in exchange for China's responsible behaviours. Eventually, China retrieved its tariff autonomy in 1930.

Published: April 2023

AbstractA miniaturized and flexible frequency-selective surface (FSS) has been presented in this article with a unit cell size of 0.049 λc × 0.049 λc where λc is the free space wavelength at the lower cut-off frequency. In order to achieve an ultra-wide (−3 dB) second order pass band of 151.3% with enhanced selectivity factor of 0.887, a cascaded triple layered hybrid resonating structure has been proposed with symmetrical Minkowski island-shaped fractal geometry pair and spiral-shaped middle layer in optimized air gap coupling. Furthermore, 149.8% ultra-wide pass band also ascertains the conformal feature of the proposed structure. In addition to this, the proposed FSS provides the stable angular response for both TE and TM polarization. An equivalent circuit model has been synthesized for accurate frequency response. Finally, a sample prototype has been fabricated to verify the experimental validation. Excellent angular stability under large oblique incident and significant conformal characteristics ensure the compatibility of the proposed structure for electromagnetic stealth in 0.9–1.8 GHz GSM band, 2.10–2.14 GHz wireless medical telemetry band, 2.4–2.5 and 4.9–5.8 GHz WLAN band, 3.4–3.7 and 4.4–4.9 GHz sub-6 GHz 5 G band, and 3.7–4.2 GHz C band.
