Asymmetric reactions of the crude oil and natural gas markets on Vietnamese stock markets
Authors: Aladwani Jassim 
Published: February 2025

PurposeThe purpose of studying the impact of crude oil and natural gas prices on the Vietnamese stock market is to understand the relationship between energy prices and the overall performance of the financial markets. As Vietnam is an energy-dependent country, fluctuations in crude oil and natural gas prices can significantly affect various industries, including manufacturing, inflation, transportation, energy production and economic growth. These sectors are often sensitive to changes in energy costs, which can lead to shifts in corporate profitability and investor sentiment. By analyzing how crude oil and natural gas prices influence the Vietnamese stock market, policymakers and investors can provide deeper insights into the economic risks and opportunities related to energy price volatility. This paper can also provide valuable information for decision-making in sectors such as economic forecasting, risk management and investment strategies.Design/methodology/approachUsing monthly data from January 2006 to March 2024, data were collected from the Vietnamese stock market and the OPEC organization for oil prices, while data on natural gas were obtained from the EIA. The data were analyzed using vector error correction (VEC) model, impulse response function, variance decomposition test and asymmetric reactions method; the study tries to ascertain the short-term and long-term dynamic relationships between the shocks of the crude oil price and natural gas prices and their effects on the movement of the stock price. In addition, the GARCH model is applied to measure the volatility of crude oil and natural gas prices.FindingsCrude oil price shocks have a statistically significant impact on most Vietnamese real stock market indices, except for the utility and consumer indices and some energy companies. Conversely, natural gas price shocks do not significantly affect on Vietnamese stock market indices, except for the energy index and some energy companies. Some “important” of both crude oil price and natural gas price shocks tend to depress the stock returns of energy companies. An increase in both crude oil and natural gas volatility can lead to heightened speculation in certain indices, particularly the energy and industrial indices, as well as in some energy companies. This heightened speculation often results in elevated of their stock returns.Originality/valueThis study provides valuable insights into the field of study examining how fluctuations in the prices of oil and gas, particularly during major crisis periods such as global financial crisis, COVID-19 pandemic and the Russo-Ukrainian War, affect financial markets.

PurposeHotel management and academia are increasingly interested in corporate social responsibility (CSR) and charismatic leadership. In this context, the present study examines how charismatic leaders affect employee quality of life through CSR practices in hotels.Design/methodology/approachThe survey encompassed employees working at either three-star or five-star hotels in Oman. The model was tested using data gathered from 396 hotel employees.FindingsResults showed that charismatic leadership positively affects CSR-induced intrinsic and extrinsic attributions. CSR positively affected task significance and intrinsic quality and negatively affected turnover intention. Quality of life predictors had a considerable impact, with intrinsic quality and turnover intention standing out. There was no significant effect of task significance on quality of life. The relationship between charismatic leadership and CSR was stronger for employees in five-star hotels and weaker for employees in three-star hotels. The CSR role mediates the relationship between charismatic leadership and quality of life.Practical implicationsThe results indicate that charismatic leaders exert a substantial impact on employees’ attributions of CSR. Upper-level management must emphasize fostering the cultivation of charismatic leadership attributes among non-charismatic leaders as a means to enhance employees’ perceptions of CSR.Originality/valueFew studies have focused on analyzing employees’ perceptions of CSR activities on a micro level. Investigating CSR phenomena in the context of internal stakeholders, especially employees, is very rare.

Published: February 2025

AbstractThe treatment of pemphigus vulgaris (PV) often requires long‐term systemic corticosteroids. Although new biologicals like rituximab are changing the landscape, traditional immunosuppressants still prevail in many underdeveloped areas. One such medication is methotrexate (MTX), which has been widely used in autoimmune and autoinflammatory diseases, but its role in treating pemphigus remains somewhat unclear and controversial. This study aimed to evaluate the effect and safety profile of using low‐dose MTX in PV patients receiving glucocorticoids. PV patients who visited the Department of Dermatology, Peking University First Hospital from January 2010 to December 2021 were retrospectively screened. Based on different treatment regimens, patients were automatically divided into a corticosteroid monotherapy group and a corticosteroid combined with low‐dose MTX group (MTX was administered at a dose of no more than15 mg per week, with a minimum duration of 8 weeks). All patients were followed up for 1 year. A total of 142 patients with PV were eligible for the study (100 in the corticosteroid monotherapy group and 42 in the corticosteroid combined with low‐dose MTX group). The Kaplan–Meier curve indicated that the corticosteroid combined with low‐dose MTX group achieved a 50% reduction in glucocorticoid use faster, with a P value of 0.0132, especially among patients who initially received more than 60 mg of steroids per day. The inclusion of MTX reduced the occurrence of hyperpilidemia. There was not sufficient evidence to determine if the addition of MTX was associated with more bacterial infection cases for certain. The inclusion of low‐dose MTX in the corticosteroid treatment regimen for patients with PV, particularly those receiving high doses, can facilitate the reduction of glucocorticoid dosages and lower the incidence of hyperlipidemia, without increasing the risk of other adverse effects.

Published: February 2025

AbstractThe resonance of coal reservoir induced by external excitation is a kind of environment‐friendly stimulation technology. In this work, an experimental system was established to carry out the coal resonance fracturing experiments, and the change trend of fracture structure was investigated by computed tomography scanning. The results showed that under the excitation of vibration within the resonance frequency band range, the coal fracture will gradually expand to failure. There are three forms of coal fracture expansion under the condition of resonant, which are the formation of slip zones in coal, the formation of fracture at phase interface and the formation of ‘void’. When the excitation frequency is constant, the natural frequency of coal decreases gradually with the expansion of fractures, resulting in the vibration frequency gradually deviating from the natural frequency of coal, and the fracture propagation behaviour of vibrating coal gradually changes from divergence to convergence.
Tree species identity shapes the relationship between canopy cover and herb‐layer species in temperate forests
Authors: Vallé Clément , Le Viol Isabelle , Nabias Jean , Princé Karine , Gosselin Frédéric 
Published: February 2025

Abstract

The composition of canopy tree species is known to impact the distribution of herb‐layer species through various factors, such as light availability, soil structure and composition. However, relationships between these strata have been rarely demonstrated empirically across a wide range of species and large spatial areas, which could help understand and spatially predict herb‐layer species distribution patterns.

We examined the response of 85 herb‐layer species occurrence (presence/absence) distribution to the cover of 105 tree species across 7255 sites in mainland France. By accounting for site characteristics and canopy diversity, we ensured that associations between herbaceous and tree species were not a reflection of these factors. We then predicted the occurrence distribution of herbaceous species by considering these environmental factors and comparing them with the addition of individual tree species cover.

Our models revealed that tree species identity cover relationships are important for all herb‐layer species and with some strong associations between these two strata. While all herb‐layer species had increased explanatory and predictive model performance from the information added by tree species identity cover, non‐forest and open vegetation species showed the greatest increase. Non‐forest generalist species are those with the most negative associations with these canopy tree species. Models also highlighted that tree species identity cover cannot be fully replaced by unidimensional functional tree groups based on trophic, dynamic, hydric or life form classification.

Our study emphasizes that incorporating tree species identity composition can enhance the prediction of herb‐layer species occurrence distribution at new sites. Consequently, we provide an empirical demonstration of improved prediction leveraging on species associations, which synthesizes various factors challenging to measure in situ. This knowledge could guide future experiments to explore mechanisms involved, especially for the high‐magnitude associations detected.

Synthesis. Our study is an empirical demonstration of the importance of tree species identity cover in shaping the distribution of the herb layer, surpassing the effects of tree diversity alone. By considering the significance of tree species identity cover, we can inform forest management and conservation measures, improve spatial prediction of herb‐layer species distribution and better understand herb layer and tree species relationships.
Who pays for a VAT hike at an international border?
Authors: Chávez Emmanuel , Domínguez Cristóbal 
Published: February 2025

AbstractThis research studies the effects of a value added tax (VAT) reform that raised the rate from 11 to 16 per cent at localities close to international borders in Mexico. Using difference‐in‐differences, we find that the VAT hike increased prices by one‐third the size of the full‐passthrough counterfactual. Moreover, we find that workers absorbed part of the VAT hike, as the reform had a negative effect on workers’ compensation. Informality, competition across the border, worker mobility and earnings level drive the effects we find.
Ultraviolet and pulsed light treatment of spices and herbs and their products: Microbial safety, enzyme inactivation, bioactive retention, and shelf‐life extension
Authors: Pravallika Kosana , Pradhan Swadhin , Prabha Abhirami , Chakraborty Snehasis 
Published: February 2025

AbstractSpices and herbs are a crucial component of the global food industry, valued for their unique flavors, aromas, and bioactive properties. However, microbial contamination and quality degradation during production, storage, and distribution pose significant challenges. Ultraviolet (UV) and pulsed light (PL) processing have emerged as nonthermal technologies offering effective, eco‐friendly solutions for microbial decontamination and quality retention in spices. This review explores recent advancements and applications of UV and PL treatments in the spice industry, highlighting their impact on pathogenic and spoilage microbial safety, physicochemical properties, and bioactive compound retention. UV processing, primarily involving UV‐C radiation, inactivates microorganisms by disrupting DNA, offering effective surface decontamination without compromising quality of spices and herbs. PL, which utilizes high‐intensity, broad‐spectrum light pulses, extends this capability to irregularly shaped surfaces, further enhancing microbial inactivation. Both methods preserve key quality attributes such as phenolics, flavonoids, antioxidant activity, ascorbic acids, and color while mitigating sensory losses, making them attractive alternatives to conventional thermal and chemical treatments. The review also examines critical factors influencing the efficacy of these technologies, including processing parameters, spice morphology, and microbial load. Despite promising results, challenges related to regulatory approval, equipment design, and consumer acceptance remain. This comprehensive analysis underscores the potential of UV and PL technologies to revolutionize spices and herbs processing, ensuring safety and quality while aligning with sustainable and consumer‐driven demands in the food industry.

Authors: Manson Alexandra C. , Golley Rebecca K. , Johnson Brittany J. 
Published: February 2025

AbstractAimsThe views of parents/caregivers about food programs in schools internationally is not well understood. This review aimed to synthesise what parents/caregivers identify as the key features of school food programs and their perspectives of these programs globally.MethodsA mixed papers review was undertaken with a systematic search (January 2024) and screening of three databases (Scopus, Web of Science, PubMed). Eligible studies captured parent/caregiver perspectives across all school food models. Study findings were extracted using Bayesian methods to translate quantitative findings into qualitative data. Data was deductively categorised to identify features of school food models, and separately themed to identify parent perspectives.ResultsTwenty‐six eligible studies were identified from 11 countries. Fifteen features were identified, including cost, time, effort and convenience, child preferences, nutrition, policy and messaging, eating environment and food education. Parent perspective themes were: child is the priority, lunchbox procurement, preparation and provision is challenging, school‐provided meals have strengths and limitations, and parents acknowledge they are central to feeding. An overarching theme was that compromises must be made to meet the needs of family members, when parents make decisions on school food.ConclusionsThis review found that globally parents perceive benefits and challenges to school food programs, regardless of provision model, with a range of features that influence parent acceptability. Considering parent/caregiver perspectives when developing or changing school food provision models is likely to increase caregiver acceptability, supporting children to engage with health promotion efforts.
