Determinants and Consequences of Risk Disclosure: Evidence from Chinese Stock Markets during the COVID-19 Pandemic

ABSTRACT This study examines the determinants and consequences of firms’ disclosures related to the COVID-19 pandemic in annual financial reports in China. First, we find that firms with high growth opportunity or low stock liquidity tended to disclose COVID-19 pandemic information to mitigate information asymmetry. Second, our results show that voluntary risk disclosure significantly decreased stock risks due to the reduction of information asymmetry. We further find that stock price crash risks decreased for firms that reported risk information compared with those that did not. Our results suggest that detailed voluntary risk disclosure is needed to mitigate stock risks, especially in extreme situations.
Landscape composition and configuration affect bees in the olive agroecosystem

Olive groves constitute a landscape that covers a large area in the Mediterranean basin, with essential economic importance, but which can also have environmental importance if an olive grove landscape is designed that favours populations of beneficial insects. Bees are also essential from an economic and environmental viewpoint and are in increasing decline. This work aimed to determine the landscape parameters in the olive agroecosystem that favour bee populations. Fifteen olive groves were sampled in central Spain throughout 2015 and 2016. Bees belonging to 6 families and 24 genera were captured. The most numerous family was Halictidae, and the most numerous genus Lasioglossum. The parameter that mostly affected the abundance and richness of bee genera was the scrubland area (CAMME), with a positive effect. The olive grove area (CAO) had a negative effect in general, although the responses of the different families vary slightly. The configuration of the landscape (MSI) also positively affected bees, which indicates the importance of maintaining linear elements with wild vegetation, to contribute to the maintenance of these important insects. Environmental conditions can affect the importance of olive grove as a supplier of resources for bees, being greater in dry and warm years.
Parental involvement in homework of children with learning disabilities during distance learning: Relations with fear of COVID‐19 and resilience

Abstract The present study investigated parental involvement in the homework of children with learning disabilities, during distance learning due to the coronavirus disease 2019 (COVID‐19) pandemic. Also, the role of parents' fear of COVID‐19 and resilience in their involvement in homework was examined. The study involved 271 parents (140 mothers and 131 fathers) of children with learning disabilities, who studied in the fifth and sixth grade from4 schools of Thessaloniki (Greece). Parents completed a set of self‐reported questionnaires, which included a scale on parental involvement in homework, a scale on fear of COVID‐19, and a scale on resilience. According to the results, both mothers and fathers expressed a high fear of COVID‐19, a low sense of resilience, and were involved in homework mostly in terms of parental control. Parental involvement in homework was not significantly differentiated by children's gender and grade. Furthermore, the path analysis model showed that parents' fear of COVID‐19 predicted, indirectly and positively, parental control through the mediating role of resilience. The findings show how parents' current emotional state affects their involvement in the homework of children with learning disabilities. Finally, the findings imply the need for parental counseling during the pandemic, to feel more resilient and consequently supportive towards children's learning.
Social capital during the coronavirus pandemic: the value of corporate benevolence

ABSTRACT In this paper, we explore market reaction to announcements of corporate donations associated with the COVID-19 crisis. Companies with larger firm size, higher leverage, higher institutional ownership, and higher ESG rankings are more likely to donate COVID relief. We observe statistically significant positive abnormal returns over the event window, driven by a subsample of community relief funds. Our results support the notion of a strategic, reputational premium for participating firms. Consistent with signalling theory, we find firms without ESG scores show positive share price responses to corporate benevolence announcements. This finding suggests the market is less likely to anticipate corporate acts of benevolence from firms with missing ESG scores. Our findings suggest that the market positively reacts to corporate philanthropy news during a crisis. The strongest stock market reaction is related to those firms with missing or less favourable ESG scores.
Quantitative Distribution of English and Indonesian Motion Verbs and Its Typological Implications: A case study with the English and Indonesian versions of the Twilight novel

This paper investigates the quantitative distribution (type and token frequencies, and type-per-token ratio [TTR]) of motion verbs found in English and Indonesian versions of the novel Twilight (Meyer, 2005; Sari, 2008). The study is contextualized within two divergent views on the typological characteristics of Indonesian lexicalization patterns of motion events. One study (Son, 2009) suggests that Indonesian behaves like English, representing a satellite-framed pattern (i.e., lexicalizing Manner of motion in the main verb) while another study (Wienold, 1995) argues for the verb-framed nature of Indonesian (i.e., lexicalizing Path of motion in the main verb). We seek to offer a quantitative perspective to these two proposals. Our study shows that, compared to English, Indonesian has significantly higher number (i.e., types) and occurrences (i.e., tokens) of Path verbs (reflecting the verb-framed pattern). Moreover, the higher TTR value of Path verbs for Indonesian shows a greater lexical diversity in the inventory of Indonesian Path verbs compared to English. In contrast, the English Manner verbs are significantly higher in number and in token frequency than Indonesian (suggesting the satellite-framed pattern), and show greater lexical diversity given the higher TTR value. While these findings lean toward supporting the verb-framed pattern of Indonesian (Wienold, 1995), we caution with the limitation of our conclusion and offer suggestions for future study.

Investigating the Demographic Characteristics of Institutional Investors Affecting Representativeness, Conservatism and Overconfidence Biases in their Individual Investments

This study aims to identify the factors affecting representativeness, conservatism, and overconfidence biases in a sample of Turkish institutional investors. In difference to other studies, especially the individual investments of institutional investors in capital markets are focused on. The respondents who are selected with the method of convenience sampling are asked survey questions. In the study, models are formed with the stepwise method using linear regression analysis, and survey questions that are assumed to represent the examined biases are selected as the dependent variable. The age, gender, marital status, education, whether or not having children, and experience of institutional investors are included in the analysis as the independent variables. This way, which of the independent variables that are found to be statistically significant and the subcategories of these independent variables are most influential on the biases is revealed. As a result of the analysis, in addition to determining the variables that affect a single bias, it is understood that the variable of education level affects all examined biases, and especially the effect of low education levels on the examined biases is higher. In the regression analysis, experience is identified as a significant variable affecting representativeness and conservatism biases. It is observed that especially the institutional investors who are inexperienced or less experienced interact with these two biases more in their decisions related to their individual investments. Gender is found to be significant variable on both conservatism and representativeness biases, especially it was understood that female institutional investors were more effective than men on the representativeness and conservatism bias. Furthermore, it is determined that the marital status variable and the divorced institutional investors as a subcategory of this variable are significantly influential on conservatism and overconfidence biases.
A Joint Soil‐Vegetation‐Atmospheric Modeling Procedure of Water Isotopologues: Implementation and Application to Different Climate Zones With WRF‐Hydro‐Iso

Water isotopologues, as natural tracers of the hydrological cycle on Earth, provide a unique way to assess the skill of climate models in representing realistic atmospheric‐terrestrial water pathways. This study presents the newly developed WRF‐Hydro‐iso, which is a version of the coupled atmospheric‐hydrological WRF‐Hydro model enhanced with a joint soil‐vegetation‐atmospheric description of water isotopologue motions. It allows the consideration of isotopic fractionation processes during water phase changes in the atmosphere, the land surface, and the subsurface. For validation, WRF‐Hydro‐iso is applied to two different climate zones, namely Europe and Southern Africa under the present climate conditions. Each case is modeled with a domain employing a 5 km grid‐spacing coupled with a terrestrial subgrid employing a 500 m grid‐spacing in order to represent lateral terrestrial water flow. A 10‐year slice is simulated for 2003–2012, using ERA5 reanalyses as driving data. The boundary condition of isotopic variables is prescribed with mean values from a 10‐year simulation with the Community Earth System Model Version 1. WRF‐Hydro‐iso realistically reproduces the climatological variations of the isotopic concentrations δPO18 and δPH2 from the Global Network of Isotopes in Precipitation. In a sensitivity analysis, it is found that land surface evaporation fractionation increases the isotopic concentrations in the rootzone soil moisture and slightly decreases the isotopic concentrations in precipitation. Lateral terrestrial water flow minorly affects these isotopic concentrations through changes in evaporation‐transpiration partitioning.
Capillary Flow in Cotton Fabric Based on Fiber Orientation Probability Density Function

ABSTRACT In natural fiber fabrics such as cotton fabric, bleeding and dye transfer in household washing have always been a concern. Due to the complex fabric structure and the closed washing process, a dynamic model for predicting the concentration of bleed dyes and soils in the fabric is lacking. This study uses the fiber orientation probability density function based on the fiber radius and the fiber volume fraction to build a capillary flow model of the fabric’s dye concentration. The numerical results were calculated by taking the hydrolyzed reactive black 5 solutions in the cotton fabric. The calculation matches the experimental results well. Numerical results show that the fabric’s washing time should be appropriately reduced to inhibit the dye transfer. Also, reducing the surface tension will result in a lower soil concentration. Increasing the fabric washing system’s viscosity is another way to slow down the hydrolyzed dyes into the fabric. More discussions about different soils with complex boundary conditions and fabric structures will be conducted in the future.
Multiple-step value-at-risk forecasts based on volatility-filtered MIDAS quantile regression: Evidence from major investment assets

Forecasting multiple-step value-at-risk (VaR) consistently across asset classes is hindered by the limited sample size of low-frequency returns and the potential model misspecification when assuming identical return distributions over different holding periods. This paper hence investigates the predictive power for multi-step VaR of a framework that models separately the volatility component and the error term of the return distribution. The proposed model is illustrated with ten asset returns series including global stock markets, commodity futures, and currency exchange products. The estimation results confirm that the volatility-filter residuals demonstrate distinguished tail dynamics to that of the return series. The estimation results suggest that volatility-filtered residuals may have either negative or positive tail dependence, unlike the unanimous negative tail dependence in the return series. By comparing the proposed model to several alternative approaches, the results from both the formal and informal tests show that the specification under concern performs equivalently well if not better than its top competitors at the 2.5% and 5% risk level in terms of accuracy and validity. The proposed model also generates more consistent VaR forecasts under both the 5-step and 10-step setup than the MIDAS-Q model.

Identification of Risk Factors for Coexisting Sinusitis and Inflammatory Bowel Disease

Abstract Background This study aimed to analyze the association of coexisting sinusitis and inflammatory bowel disease (IBD), establish significant factors involved in their development, and enable further biological correlation between these 2 diseases. Methods The IBD and Sinusitis Study at UChicago Medicine (TISSUe) is a retrospective, single-center study. We reviewed patients to confirm IBD and chronic sinusitis diagnoses. Case-control propensity score matching was performed using matched controls with IBD only or sinusitis only. Statistical methods included chi-squared test and Wilcoxon rank sum test. Logistic regression analysis was performed, and factors were considered significant if P < . 05. Results Stratifying 214 patients with coexisting IBD and sinusitis, 176 patients had IBD first and 38 patients had sinusitis first. Multivariable analysis of factors associated with subsequent disease with matched controls determined that duration of disease, UC, steroid exposure ever, and younger age of IBD diagnosis were associated with subsequent sinusitis in patients with IBD; steroid exposure ever and duration of sinusitis were significantly associated with subsequent IBD in patients with sinusitis. Conclusion This study suggests that IBD maintenance therapies are not associated with increased risk of sinusitis, as proposed by adverse events in clinical trial data; rather, UC diagnosis and duration of disease may be more influential in sinusitis development. While further studies are necessary, this study also demonstrates that sinusitis precedes IBD in some patients, probing its biological association with IBD and possible classification as an extraintestinal manifestation.
Probation officer discretion in monitoring and violating supervision conditions

Probation is a sentence served in the community and includes a number of supervision conditions. If the conditions are violated, individuals could receive a sanction, including revocation. Not every violation, however, may receive a consequence. Probation officers have discretion for how they manage individuals on the caseloads. This study used qualitative data from two departments in a MidWest state in the United States, one rural and one urban, to explore officer decision-making in supervision. It is critical to examine these factors due to the high number of individuals revoked from probation each year. The study findings illustrate the factors officers use in monitoring conditions, as well as in violations and revocations.
Demonstrating 170 °C Low-Temperature Cu–In–Sn Wafer-Level Solid Liquid Interdiffusion Bonding

The wafer-level solid liquid interdiffusion (SLID) bonds carried out for this work take advantage of the Cu–In–Sn ternary system to achieve low-temperature interconnections. The 100-mm Si wafers had <inline-formula> <tex-math notation="LaTeX">$\mu $ </tex-math></inline-formula>-bumps from <inline-formula> <tex-math notation="LaTeX">$250~\mu \text{m}$ </tex-math></inline-formula> down to <inline-formula> <tex-math notation="LaTeX">$10~\mu \text{m}$ </tex-math></inline-formula> fabricated by consecutive electrochemical deposition of Cu, Sn, and In layers. The optimized wafer-level bonding processes were carried out by EV Group and Aalto University across a range of temperatures from 250 °C down to 170 °C. Even though some quality-related process challenges were observed, it could be verified that high strength bonds with low defect content can be achieved even at a low bonding temperature of 170 °C with an acceptable 1-h wafer-level bonding duration. The microstructural analysis revealed that the bonding temperature significantly impacts the obtained phase structure as well as the number of defects. A higher (250 °C) bonding temperature led to the formation of Cu<sub>3</sub>Sn phase in addition to Cu<sub>6</sub>(Sn,In)<sub>5</sub> and resulted in several voids at Cu<sub>3</sub>Sn|Cu interface. On the other hand, with lower (200 °C and 170 °C) bonding temperatures, the interconnection microstructure was composed purely of void-free Cu<sub>6</sub>(Sn,In)<sub>5</sub>. The mechanical testing results revealed the clear impact of bonding quality on the interconnection strength.
Split Tibialis Anterior Transfer for Correction of Residual Dynamic Metatarsus Adductus Following Ponseti Management of Idiopathic Clubfoot

Background: Clubfoot represents one of the most common congenital orthopedic deformities. It affects 1-2/1000 live births all over the world. Cases of dynamic and severe deformity represent a challenging problem. This is because the conservative management is not effective as well as the surgical options are little. Objective: Aim of the present study was to evaluate the better management of split tibialis anterior tendon transfer in the treatment of residual clubfoot. Patients and methods: Eighteen cases (22 feet) with residual dynamic supination deformity following previous Ponseti management underwent split transfer of the anterior tibial tendon. This was a prospective study between March 2020 and February 2021, the cases were collected and the study was carried out at Zagazig University Hospitals. Results: In our study, the mean age was 41.05 months (ranged from 30 to 59 months). Out of the 18 patients, there were 12 males and 6 females. Four cases (22.2%) were bilaterally affected. While 14 patients (77.8%) were one-side affected (5 left foot affected and 9 right foot affected). Our results showed marked improvement of patients according to Garceau and Palmer’s criteria as the mean pre-operative assessment was 2.5 reaching 3.28 post-operatively. 14 patients (88.9%) were either poor or fair and no single patient was excellent pre-operatively, while postoperatively all patients became either excellent mostly or good. Conclusion: Anterior tibial tendon transfer is a reasonable method of achieving the objective, either fully or split transfer because both operations have excellent results with low rate of major complications. It's very simple but yet very effective soft-tissue procedure to correct the muscle imbalance of the foot.
Operating Limits for Low-Capacitance Cascaded H-Bridge Static Compensators

The cascaded H-bridge (CHB) low-capacitance static compensator (LC-StatCom) has a limited inductive region compared to a conventional StatCom, both in balanced and unbalanced conditions, due to the inherent large oscillations on the capacitor voltages. This article presents a detailed analysis of the viable operating region in these converters that takes into account the inherent large oscillations. The analysis facilitates sizing of the dc-link capacitors to ensure that the StatCom is able to inject a given range of positive- and negative-sequence current. Though the analysis is generic and applicable to the CHB StatComs with relatively large capacitance values, it is more relevant in the LC-StatComs. In addition, the article derives reference steady-state signals that can be used as feedforward terms in LC-StatCom control loops to enhance the control performance. The article presents simulation and experimental results, in balanced and unbalanced conditions to corroborate the proposed analysis.

How Do Populist Radical Right Parties Differentiate their Appeal? Evidence from the Media Strategy of the Hungarian Jobbik Party

Abstract As they become more successful, populist radical right parties face a tension between keeping their nativist credentials and moderating their appeal to gain new voters. We argue that differentiating party messages to core supporters and the wider electorate allows parties to pursue both goals. We outline and empirically illustrate the previously underexplored phenomenon of selective messaging based on the communication strategy of the Hungarian Jobbik party throughout its lifespan (2006–19) in partisan outlets, press releases and Facebook. Using a dictionary approach, we map the co-evolution of populist and nativist mobilization under conditions of supply- and demand-side changes. Our results show the decline and transformation of Jobbik's nativist appeal, and an increasing reliance on populism. The trend is not uniform; Jobbik relies on nativism as a function of targeting party identifiers or the general electorate in specific media outlets. Our findings show the importance of mapping parties’ programmatic appeal across platforms and over time.
