The presence of underground quarries in North France in close proximity to urbanized areas, imposes serious problems in terms of security of both people and constructions at one hand, and induces a strong constraint against planning and urban development on the other hand. The purpose of this paper is to provide a practical tool for the preliminary estimation of the stability of underground quarries.

In this paper, a numerical stability study of quarries, excavated in chalk of North France with or without joints, by the method of rooms and pillars, is presented. This integrates the data provided from site: mechanical properties of the chalk and geometric characteristics of the quarries (width of the pillar W, height of the pillar H and span between pillars L), as well as the orientation of the joints (α). Numerical parametric analysis is conducted using FLAC 3D. Factors of safety are computed from the numerical models. Then, a second-order regression technique is applied on these numerically obtained factors, to correlate new formulae.

As a result, user-friendly formulae for the calculation of factors of safety Fs (ex) are extrapolated. Besides, abacuses to determine the minimum permissible effective width of safe pillars are proposed.

By this, it becomes possible, knowing only few parameters about geometry and properties, to give a fast estimation of the stability state of any quarry in the region.

Exploiting a novel measure of hostile takeover exposure primarily based on the staggered adoption of state legislations, we explore a crucial, albeit largely overlooked, aspect of corporate social responsibility (CSR). In particular, we investigate CSR inequality, which is the inequality across different CSR categories. Higher inequality suggests a less balanced, more lopsided, CSR policy.

In addition to the standard regression analysis, we perform several robustness checks including propensity score matching, entropy balancing and an instrumental-variable analysis.

Our results show that more takeover exposure exacerbates CSR inequality. Specifically, a rise in takeover vulnerability by one standard deviation results in an increase in CSR inequality by 4.53–5.40%. The findings support the managerial myopia hypothesis, where myopic managers promote some CSR activities that are useful to them in the short run more than others, leading to higher CSR inequality.

Our study is the first to exploit a unique measure of takeover vulnerability to investigate the impact of takeover threats on CSR inequality, which is an important aspect of CSR that is largely overlooked in the literature. We aptly fill this void in the literature.

Recent studies have shown that hyperuricemia is a predictor of non-communicable disease and an increment of mortality rate. Also, elevated serum uric acid may be associated with obesity in the adult population. This study aims to evaluate the association between serum uric acid levels with metabolic parameters and risk of obesity in the Iranian population.

The cross-sectional study was done on 550 participants, who were referred to a hospital for elective angiography in Rasht, Iran; anthropometric indices (waist circumference (WC) and body mass index (BMI)) and hematological factors were measured using the standard approaches. Based to the angiography results, the severity of atherosclerosis was defined.

The mean (SD) concentration of serum uric acid for all participants was 5.15 (1.37) mg/dl. Individuals who were at the highest tertile had higher mean (SD) of weight (p = 0.004), creatinine and blood urea nitrogen (p < 0.001) lower fasting blood sugar (FBS) (p = 0.000) and HbA1c (p = 0.016), and they were mostly men compared with those in the lowest tertile. After adjusting for confounders, FBS (ß = –0.145, p = 0.001) and HbA1c (%) (ß = –0.130, p = 0.019) had inverse and weight (ß = 0.156, p = 0.001) had direct association with serum uric acid. After adjustment for additionally potential confounders subjects in the highest tertile of serum uric acid had 92 per cent higher chance of obesity compared with subjects in the lowest tertile (OR 1.92; 95 per cent CI 1.13, 3.23).

The present study has concluded that increase serum uric acid related to high risk of obesity and low mean of FBS and HbA1c.

The authors investigate whether firm-specific vulnerability to climate change influences foreign exchange hedging, using a novel text-based measure of firm-level climate change exposure generated by state-of-the-art machine-learning algorithms.

The authors' empirical analysis includes firm-fixed effects, random-effects regressions, propensity score matching (PSM), entropy balancing, an instrumental-variable analysis and using an exogenous shock as a quasi-natural experiment.

The authors' findings suggest that greater climate change exposure brings about a significant reduction in exchange rate hedging. Companies more exposed to climate change may invest significant resources to address climate change risk, such that they have fewer resources available for currency risk management. Additionally, firms seriously coping with climate change risk may view exchange rate risk as relatively less important in comparison to the risk posed by climate change. Notably, the authors also find that the negative effect of climate change exposure on currency hedging can be specifically attributed to the regulatory aspect of climate change risk rather than the physical dimension, suggesting that companies view the regulatory dimension of climate change as more critical.

Recent studies have demonstrated that climatic fluctuations represent one of the most recent sources of unpredictability, thereby impacting the economy and financial markets (Barnett et al., 2020; Bolton and Kacperczyk, 2020; Engle et al., 2020). The authors' study advances this field of research by revealing that company-specific exposure to climate change serves as a significant determinant of corporate currency hedging, thus expanding the existing knowledge base.

Political participation of young people has been examined, but there is a lack of research about how these participation forms are interpreted and what counts as participation for young people. The study aims to identify discourses of political participation in Hungary, where the COVID-19 restrictions during 2020–2021 have confined young people's everyday interactions and political activism to the online space for an extended period. The authors’ asteroid-effect hypothesis suggests that new discourses of political participation have become more widespread, which may have reinterpreted the previous dynamics between online and offline participation.

The authors analyse the results of six focus groups and eight interviews with young people conducted between 2021–2022 through discourse analysis.

The qualitative results show that to intellectualise the everyday discourses of youth political participation, extending its classical theories is worthwhile. While online participation has not emerged as a paramount, positive interpretational framework, a new discourse of political participation has emerged, making conversation a fundamental act.

While the results are limited to Hungarian youth, the strong appearance of participation as a communicative action can have consequences to theoretical approaches of political participation. The authors believe that COVID-19 restrictions had a significant role in this change, because family talks became more politicised.

This study examines how English teachers use culturally relevant pedagogy (CRP) to support postsecondary readiness for underrepresented students in the context of dual credit (DC) coursework in the USA. Postsecondary readiness, termed “college readiness” in the USA, refers to the skills and knowledge students need to succeed at a university. DC courses are university-level classes delivered to high school students through partnerships with postsecondary institutions, most often two-year community colleges. The purpose of this study is to highlight practices and institutional conditions that enable English instructors to foster postsecondary opportunity for all.

Using an interpretive approach, this qualitative study analyzes data derived from in-depth interviews with five community college English instructors who teach DC to diverse high-school students and who apply CRP in their classroom practice.

Findings reveal that instructors used culturally relevant approaches not only to help students access dominant college-ready skills, but also to reimagine what constitutes college readiness to begin with. Instructors also took advantage of their unique positioning as postsecondary instructors working with secondary students, leaning on academic freedom to push boundaries with their curriculum.

This study shows how English instructors are uniquely positioned to enhance university preparation and build a more inclusive vision of postsecondary readiness for all students. The study also highlights institutional conditions, such as teacher autonomy, pedagogical training and administrator support, that can promote culturally relevant postsecondary preparation in English classrooms.

Theoretically, both democ/ratic legitimacy and government capacity are necessary for successful crisis management, like the COVID-19 pandemic. The authors argue that there are important variations for pandemic management in the developed and democratic world. However, are these equally needed in the developing world where democracy and capacity are present in varying degrees and in some countries with a vast deficit? This article analyzes how legitimacy and capacity affect citizens' satisfaction with the pandemic management in South Asia.

The study is based on a survey of 3,423 randomly selected respondents from Facebook users in South Asia. The survey data are presented and discussed along with information derived from secondary sources to put the data in the broader context of the South Asian countries. The authors apply ordinary linear regression for statistical analysis.

The findings suggest that citizens are content with the performance of government institutions in COVID-19 management. They emphasize material well-being, such as relief provisions and financial incentives during the crisis period. They are, however, less concerned about the legitimacy dimension, although democracy in South Asia is flawed with excessive restrictions on public freedom during the pandemic. The contradictory findings may be due to the public orientation towards authoritarian culture and their preference for strongman rule in crisis management.

The governments in South Asia may systematically use army and police forces to manage crises as people are more satisfied with their performance during COVID-19 management.

This is the first time data across South Asia have been collected and analyzed about crisis management.

Crises precipitate strong fiscal responses by government – sometimes toward austerity, other times toward renewed social spending. This variation in approaches to crisis handling has the potential to highlight factors that drive public opinion toward government interventions that may be quite different from those in non-crisis times. This study aims to discuss the aforementioned issues.

This article brings together theories of government policymaking in crises, policy responsiveness and economic voting to assess how personal financial (egocentric) concerns and/or national financial (sociotropic) concerns may influence opinions toward government handling of direct financial supports in a crisis and, more generally, opinions toward social policy interventions. The authors assess this dynamic in the Canadian context using original national survey data collected in the initial stage of the pandemic-based crisis in June and July of 2020 (N = 1290).

The authors find strong evidence in support of sociotropic concerns shaping government approval and support for greater social policy interventions, but limited evidence to support egocentric concerns, suggesting that social policy attitudes may be more insulated from personal factors than anticipated.

The authors’ findings suggest that crises may prompt enhanced support for interventionist social policy measures that may lack broad-based support in non-crisis times.

The authors’ findings speak to the ongoing discussion around the possibility for crises to function as policy windows for enhanced social spending and for entrenching targeted financial supports for vulnerable individuals.

The paper discusses the predictors of trust in the institutions and people involved in crisis management at the beginning of the COVID-19 pandemic in Romania. Trust in institutions might be a key factor in the way countries affected by the COVID-19 pandemic deal with the crisis as people might be more willing to accept the restrictions and rules imposed if they trust the key institutions and people involved in managing the pandemic. The paper provides recommendations for key stakeholders to increase trust in people and institutions in times of crisis.

The authors draw evidence from a national online panel survey (N = 1,160) to investigate the main predictors of trust in this context.

The main results indicate that trust in institutions is positively correlated with news consumption and personal discussions about the pandemic, perceived incidence of COVID-19 fake news, belief in conspiracy theories and uncertainty about the future of the country.

To the best of the knowledge, this study is one of the few papers investigating the predictors of trust in the institutions and people involved in managing the current pandemic in a country in the Central and Eastern European region.

This paper aims to analyze conflict resolution strategies among individuals who encountered disputes with family, neighbors, workmates, businesses, strangers, government authorities or other members in their communities during the COVID-19 pandemic.

Applying a difference-in-difference approach by sex, the authors use a representative panel of adults living in 82 cities from across Mexico to measure changes in antisocial strategies (violence) and prosocial strategies (non-confrontational methods and dialogue) to resolve disputes.

During the COVID-19 pandemic, men reduced their use of violence by 19.6% while women did so by 17.4%. There was a parallel rise in non-confrontational strategies used to solve conflicts equal to 73.6% for men and 62% for women. The use of dialogue as a tool for resolving disputes increased by more in cities that banned the sale of alcohol. Alternative Twitter data corroborates the main findings, suggesting that individuals are becoming more prosocial during the pandemic.

To the knowledge, this is the first empirical study to analyze changes in strategies for conflict resolution as a consequence of the COVID-19 pandemic. This paper contributes to the literature by demonstrating how individuals adapt their dispute strategies under extraordinary circumstances such as a pandemic, with a focus on a middle-income setting.
