In order to improve the effectiveness of financial credit risk control, a financial credit risk control strategy based on weighted random forest algorithm is proposed. The weighted random forest algorithm is used to classify the financial credit risk data, construct the evaluation index system, and use the analytic hierarchy process to evaluate the financial credit risk level. The targeted risk control strategies are taken according to different risk assessment results. We compared the proposed method with two other methods, and the experimental results show that the proposed method has higher classification accuracy of financial credit data and the risk assessment threshold is basically consistent with the actual results.

Motivated by the Basel III requirement we analyze an optimal Capital Adequacy Ratio subject to foreclosure risk exposure. We assume that the banker invests in treasuries, a stock index and a loan portfolio, where he/she wishes to maximize his/her expected utility of terminal wealth by selecting optimal investment and risk control strategies. The dynamics of the stock index and the banker’s risk exposure towards foreclosure is modeled as two independent compensated pure jump Lévy Processes. By applying the martingale approach we obtain a closed form solution for this optimization problem under a quadratic utility function. A negative correlation between the banker’s foreclosure risk and the price dynamics of stock index will result in a reduced amount invested in stock index fund while a positive correlation between the banker’s foreclosure risk and the price dynamics of stock index will increase the amount invested in stock index fund.

Abstract Throughout the past couple of decades, the surge in the sale of equity-linked products has led to many discussions on the evaluation and risk management of surrender options embedded in these products. However, most studies treat such options as American/Bermudian style options. In this article, a different approach is presented where only a portion of the policyholders react optimally due to the belief that not all policyholders are rational. Through this method, a probability of surrender is obtained based on the option moneyness and the product is partially hedged using local risk-control strategies. This partial hedging approach is versatile since few assumptions are required for the financial framework. To compare the different surrender assumptions, the initial capital requirement for an equity-linked product is obtained under a regime-switching equity model. Numerical examples illustrate the dynamics and efficiency of this hedging approach.

Oxide Nanoparticles

Over the past decade, the production and applications of metal-based and metal-oxide nanoparticles (MBNPs and MONPs, respectively) have increased significantly due to their enhanced physicochemical properties and biological activities when compared with their bulk parent materials. Once MBNPs and MONPs enter agricultural soil via direct or indirect pathways, they can interact with crop plants and thus pose a threat to both animal and human health through food chain pathways. Although many review articles on engineered nanoparticles have been published, few have focused on the interactions of MBNPs and MONPs with crop plants and their current applications. Therefore, we reviewed the sources and behaviors of MBNPs and MONPs in agricultural soil, physiological and biochemical effects of MBNPs and MONPs on plants, uptake, translocation of MBNPs and MONPs in crop plants, factors affecting the interaction between MBNPs and MONPs and plants, and the applications of MBNPs and MONPs. Lastly, we propose where the future research priorities should be focused to provide a better understanding of MBNPs and MONPs. This review will help to promote scientific research regarding MBNPs and MONPs and to understand the risks and benefits of their association with plants and will contribute to the advancement of nanotechnology.

The main purpose of this article was to study the risk management of terminal on-site operations for special bulk cargos in Taiwan. This study applied the concept of Formal Safety Assessment approach as the foundation of risk management assessment. At first, a total of four risk aspects with eighteen preliminary risk factors were generated from literature and experts interviews. Three methods – namely analytical hierarchy process (AHP), risk matrix model (RMM), and costs and benefit analysis (CBA) methods – were employed to perform an empirical study in Taiwan. The empirical results showed: (1) The most severe risk factor found using the AHP method was ‘failure to perform periodic machinery maintenance and examination.’ (2) Ten risk factors placed in the highest-risk area via the RMM method. (3) All risk control strategies were evaluated for applicability by using the CBA method. This study recommended that improvement and reinforcement of the staff aspect and the related risk factors for the on-site operation of special bulk cargos. Through implementation of risk control strategies, the risks of accidents can be controlled.
