Thin-walled spread foundations are used in coastal projects where the soil strength is relatively low. Developing a predictive model of bearing capacity for this kind of foundation is of interest due to the fact that the famous bearing capacity equations are proposed for conventional footings. Many studies underlined the applicability of artificial neural networks （ANNs） in predicting the bearing capacity of foundations. However, the majority of these models are built using conventional ANNs, which suffer from slow rate of learning as well as getting trapped in local minima. Moreover, they are mainly developed for conventional footings. The prime objective of this study is to propose an improved ANN-based predictive model of bearing capacity for thin-walled shallow foundations. In this regard, a relatively large dataset comprising 145 recorded cases of related footing load tests was compiled from the literature. The dataset includes bearing capacity （Qu）, friction angle, unit weight of sand, footing width, and thin-wall length to footing width ratio （Lw/B）. Apart from Qu, other parameters were set as model inputs. To enhance the diversity of the data, four more related laboratory footing load tests were conducted on the Johor Bahru sand, and results were added to the dataset. Experimental findings suggest an almost 0.5 times increase in the bearing capacity in loose and dense sands when LJB is increased from 0.5 to 1.12. Overall, findings show the feasibility of the ANN-based predictive model improved with particle swarm optimization （PSO）. The correlation coefficient was 0.98 for testing data, suggesting that the model serves as a reliable tool in predicting the bearing capacity.

Consistent climatic perturbations have increased global environmental concerns, especially the impacts of abiotic stresses on crop productivity. Rice is a staple food crop for the majority of the world’s population. Abiotic stresses, including salt, drought, heat, cold and heavy metals, are potential inhibitors of rice growth and yield. Abiotic stresses elicit various acclimation responses that facilitate in stress mitigation. Plant hormones play an important role in mediating the growth and development of rice plants under optimal and stressful environments by activating a multitude of signalling cascades to elicit the rice plant’s adaptive responses. The current review describes the role of plant hormone-mediated abiotic stress tolerance in rice, potential crosstalk between plant hormones involved in rice abiotic stress tolerance and significant advancements in biotechnological initiatives including genetic engineering approach to provide a step forward in making rice resistance to abiotic stress.

Personality Disordered (herein referred to as PD) clients are challenging to statutory mental healthcare programmes. They can be difficult to diagnose: their disorders can be obscured by second-order problems such as anxiety and depression, caused by PD cognitive processes. Treatment-as-usual (the predominant model of psychiatric intervention) for PD clients in crisis tends to focus on these second-order presentations, but provide no means of identifying underlying PD. The purpose of this paper is to describe how heuristic methods of diagnosis can be used to reframe the client’s distress in the context of personality disorders (according to DSM-IV criteria), and how subsequent application of integrative therapies can break their cycle of recidivism. Method: Two case studies of treatment-refractory individuals with cyclical patterns of crisis-point service engagement for self-harm or psychotic depression where heuristic/ integrative therapies were used. Results: The use of integrative therapies in the case studies presented resulted in a marked change in recidivism and quality of life for each client, as measured by a significant reduction in presentation of symptoms and hypervigilance. Discussion: By understanding the maladaptive cognitive-behavioural processes of PD clients, they can be modified to reduce the client’s self-defeating behavioural patterns, breaking the cycle of recidivism. However, a new diagnostic strategy must first be formulated that looks at the clients past use of mental health services to detect underlying PD.
