Summary: The weakest link in a cyber secure system is often the people who configure, manage or use it, with security breaches being attributed to human error. Companies implement strong security policies and provide specific training to minimize phishing attacks, but the effectiveness relies on individual adherence.

Summary: Although SMEs play a crucial role in developing and growing economies, little is known about their use of management control tools. A holistic system is needed in SME management control to study how each lever affects organizational performance. This article proposes a fuzzy logic approach for decision-making and applies the MFIS technique to explore the impact of management control tools on SME organizational performance, with data analysis obtained through empirical research.

Summary: This paper investigates the impact of the river chief system (RCS), a decentralized policy in China for water protection, on firm-level emission abatement and profits. The study finds that the RCS significantly reduces COD emissions, particularly in heavily polluting industries, non-state-owned firms, and firms in the eastern provinces. However, it also increases profits for polluting firms, especially in heavily polluting industries. The paper also reveals regional variations in pollution abatement strategies and the potential transfer of negative shocks from the RCS along the production line.

Summary: This paper examines the identification and counterfactual bounds for heterogeneous firms that can be ranked based on their productivity. The paper develops a methodology that can be applied even when quantities and prices are unobservable. Instead, the study requires information on profits, costs, or revenues, as well as prices or price proxies for selected variables. The paper also extends classical duality results to a scenario with discrete heterogeneity, endogeneity, and limited variation in potentially latent prices. Finally, the paper demonstrates the conversion of convergence results for nonparametric estimators into convergence results for production sets.

Summary: Multi-drug chemotherapy improves the success rate of cancer treatment, but incorrect drug concentration selection can affect the patient's body. To address this issue, researchers proposed a closed-loop multi-drug scheduling based on fractional-order internal-model-control proportional integral (IMC-FOPI) control. Experimental results showed that compared to conventional controllers, this control scheme improved the settling time in drug concentration control at the tumor site. Therefore, it can be concluded that the proposed control scheme is more efficient than conventional controllers.

Summary: This study uses transaction data to examine trading styles and profitability in a leading derivatives market. The findings suggest that retail investors predominantly hold simple, one-sided positions in only one class of options, while institutional investors are more likely to use complex strategies. Additionally, the study reveals that retail investors using simple strategies perform worse than the rest of the market, and selling volatility is the most successful strategy for both retail and institutional investors.

Summary: In this study, a central cooling water system is modeled and optimized using Matlab Simulink. The PI controllers of the system are tuned using internal model control (IMC) filters, and a modified IMC method is proposed to simplify the tuning process. The results show that the proposed methods can improve the efficiency of the seawater pump and the operation of the three-way valve while maintaining reasonable control of the outlet temperature.

Summary: Inadequate disposal of Municipal Solid Waste (MSW) is a major environmental issue today. Incineration, also known as mass burning, is a controversial but widely used method for MSW disposal in Europe, Japan, the US, and China. This article reviews the global progress of waste-to-energy recovery and mass-burning technologies, focusing on the Brazilian context. The study examines the benefits, impacts, and regulatory frameworks of these technologies, and provides insights into the electricity generation capacity and licensing processes of Waste-to-Energy Plants (WtEPs) in Sao Paulo state.

Summary: The concentrations of bioactive compounds in orange juice are affected by different citrus scion/rootstock combinations. Packaging and storage can optimize the shelf life of freshly squeezed juice. The combination of 'Rubi' orange in both 'Rangpur' lime and 'Swingle' citrumelo rootstocks showed higher concentrations of ascorbic acid and dehydroascorbic acid. Overall, scions grafted onto 'Swingle' citrumelo rootstock had higher concentrations of ascorbic acid, dehydroascorbic acid, and some phenolic compounds. Phenolic compounds had the highest concentrations at the time of fruit extraction and decreased during storage. Dark packaging increased the levels of bioactive compounds in juices stored for longer periods. These findings can help diversify scion/rootstock cultivars to produce pasteurized orange juice with higher nutritional value.

Summary: Climate change is affecting vegetable production through changes in rainfall patterns and soil moisture. To mitigate this, technologies such as magnetically treated water are being explored to maintain ideal soil moisture for plant uptake. This study investigated the effect of magnetically treated water on lettuce biomass and nutrient uptake, finding that it improved nitrogen assimilation and resulted in higher agronomical characteristics and yield.

Summary: Soil management systems can directly impact crop yield by altering the physical and hydraulic properties of the soil. Long-term experiments have shown that the no-tillage system improves soil density and compaction resistance, enhances root development, and increases soybean yield by 6.5%, without affecting water infiltration.

Summary: The aim of this study was to investigate the diversification of citrus cultivation to increase variety and profitability of orchards in response to environmental changes. The study was conducted in the subtropical region of Sao Paulo, Brazil. The results showed that the rootstocks had little influence on the duration of phenological intervals. Scion cultivars grafted onto RL demonstrated larger canopy volumes and better fruit quality compared to those grafted onto SC.

Summary: This study aims to evaluate the energy efficiency of a Brazilian agribusiness company's meat retail sector using PROCEL energy evaluation methods. By using PROCEL's RTQ-C manual, conducting literature research on energy issues, and understanding the company's environment, the commercial establishment received a B classification index, which is considered good but needs improvement in areas such as air conditioning for better energy efficiency. Therefore, improving these areas can lead to economic and environmental benefits for the company, and this research serves as a basis for evaluating energy efficiency in other companies in the same sector.

Summary: This study aims to evaluate the neuro-fuzzy inference method as a decision support for irrigated coriander cultivation. The experiment was conducted in two cultivation cycles in Pentecoste-CE, Brazil, and the results showed that the best results occurred at 55% irrigation depth and a range of 40 to 50% of mulch in the first cycle, while in the second cycle, the water consumption was reduced by 50 to 80%. The neuro-fuzzy model could be a viable option for decision-making in irrigated crops in semi-arid regions.

Summary: This study used a mathematical model based on fuzzy logic to estimate the replacement rates of magnetic water provided by irrigation and compared it with multiple polynomial regression analysis. The results showed that irrigating with magnetic water resulted in higher biometric values for lettuce, and the fuzzy model provided a more accurate adjustment compared to multiple polynomial regression.
