Discussion of “optimal reinsurance designs based on risk measures: a review” by Jun Cai and Yichun Chi

Empirical study on optimal reinsurance for crop insurance in China from an insurer's perspective

This study investigates the optimal reinsurance for crop insurance in China in an insurer's perspective using the data from Inner Mongolia, Jilin, and Liaoning, China. On the basis of the loss ratio distributions modeled by AnHua Crop Risk ...

Marginal Impact of climate variability on crop yields in Ghana

The impacts of climate variability indicators on crop yields have attracted global attention over the years. This is particularly so because of the growing concern about the effect of climate change on sustainable food production, especiall...

Modelling the adsorption of iron and manganese by activated carbon from teak and shea charcoal for continuous low flow

Nearly 6494 boreholes with iron (Fe) and manganese (Mn) concentrations above permissible limits of 0.3 mg/L and 0.4 mg/L respectively in Ghana have been abandoned because of ineffective water treatment solutions. Activated carbon prepared f...

Beyond airborne spread: a dual-route Wells-Riley extension for estimating norovirus infection risk in Ghanaian pediatric wards

Background: The classic Wells–Riley model (CWRM) is a well-established framework for estimating airborne infection risk in shared indoor environments. This study extends the framework to simultaneously incorporate fecal–oral transmission, a...

Changes in the geographical distribution of youth poverty and social exclusion in EU member countries between 2008 and 2017

With respect to the fulfillment of the objectives of the Europe 2020 strategy, the threat of poverty and social exclusion has not been sufficiently reduced in the European Union (EU) over the past decade, and large regional disparities pers...

Long-Term Prognosis and Systemic Impact of Acromegaly: Analyses Utilizing Korean National Health Insurance Data

Acromegaly is a rare endocrine disorder caused by excessive growth hormone secretion. Its low prevalence poses challenges in studying its long-term prognosis and systemic effects. To address this research gap, we conducted five studies usin...

Assessment of polygenic architecture and risk prediction based on common variants across fourteen cancers

In cancer many gene variants may contribute to disease etiology, but the impact of a given gene variant may have varied effect size. Here, the authors analyse summary statistics of genome-wide association studies from fourteen cancers, and ...

Modeling antiretroviral therapy adherence among people living with HIV: a cross-sectional study at Pantang Hospital, Ghana

Abstract Background Poor adherence to antiretroviral therapy (ART) continues to undermine HIV treatment outcomes in sub-Saharan Africa, including Ghana. Objective This study aimed to quantify ART treatment adherence among people living with...

APPLICATION OF THE EQUIVALENCE PRINCIPLE TO THE CALCULATION OF EDUCATION INSURANCE PREMIUMS FOR VILLAGE-OWNED ENTERPRISES (BUMDes)

Program Education plays a vital role in improving human resources. But on the other hand, education costs are not cheap. For this reason, people need to prepare education funds from an early age. One way is to take part in an education insu...

Robustness analysis of a Continuous-Time Markov Jump Process model for herd behaviour under stochastic shocks

Herd behaviour in socio-economic systems is characterised by asynchronous, stochastic decision-making that traditional models capture imperfectly. Discrete-time DTMCs impose fixed-tick synchrony and require binning, which distorts event tim...

Ranking of treatments in network meta-analysis: incorporating minimally important differences

Abstract Background In network meta-analysis (NMA), the magnitude of difference between treatment effects is typically ignored in the calculation of ranking metrics, such as probability best and surface under the cumulative ranking curve (S...

Seemingly unrelated time series model for forecasting the peak and short-term electricity demand: Evidence from the Kalman filtered Monte Carlo method

In this extant paper, a multivariate time series model using the seemingly unrelated times series equation (SUTSE) framework is proposed to forecast the peak and short-term electricity demand using time series data from February 2, 2014, to...

An artificial neural network-based model for predicting paratransit travel time

The nature of paratransit services makes for increased uncertainty in trip time, leading to reported unreliability and dissatisfaction by the users. While providing travel information has proved helpful in formal bus services and has been r...

Mathematical Modeling of Leptospirosis With Misdiagnosis

Leptospirosis is a widespread zoonotic bacterial disease that continues to pose a major public health challenge, particularly in developing countries where it causes substantial morbidity, mortality, and economic losses. A key problem in co...

Ozonation, electrochemical, and biological methods for the remediation of malachite green dye wastewaters: A mini review

The extensive usage of malachite green (MG) dyes in the fish and dye industries cause serious water pollution, leading to catastrophic effects on living organisms and the environment. In addressing the challenges of health risks related to ...

The risk of colorectal cancer according to obesity status at four-year intervals: a nationwide population-based cohort study

Abstract Obesity is a risk factor for colorectal cancer. However, the effect of body weight change on colorectal cancer is uncertain. This study aimed to investigate the relationship between difference in body mass index and the risk of col...

Darboux operators for linear first-order multi-component equations in arbitrary dimensions

Metabolomic sweet spot clock predicts mortality and age-related diseases in the Canadian Longitudinal Study on Aging

Abstract Background Chronological age does not capture individual health or resilience. Advances in metabolomics have enabled development of molecular aging biomarkers that capture deviations between biological and chronological age, highli...

How to measure consumer's inconsistency in sensory testing?

Consumer sensory testing is the basis for determining directions of product development in the food industry. However, while compliance assessment by trained and expert assessors is well developed, few information is available on testing co...
