This paper focuses on mariner-ship interaction from the practical end of the design spectrum. Statistical data on marine collisions, rammings and groundings attribute a considerable percentage of marine casualties to poor ship controllability. A vessel's controllability is of a dichotomous nature, constrained not only by its inherent controllability characteristics, fixed by the naval architect, but also by the skill and the expertise of the shiphandler in initiating a conclusive control strategy. The results of an international survey of naval architects and shiphandlers are presented. The techniques of frequency distribution and factor analysis were used to identify the key ship controllability effectors. This survey highlights where improvements in terms of interface design can be made. The survey identifies the key controllability effectors of naval architects and ship-handlers for effective mariner-ship interaction. A case study is presented which identifies the applicability of part-task ship simulation to improve confidence levels in practical ship control. For effective mariner/ship interaction, the designers of ships must use the various codes of practice for a ship's bridge in order to improve the bridge as a control station, and marine licensing authorities have to realize the potential benefits that training with computerized ship simulation can bring the industry.

Masonry buildings are ordinarily complex construction systems and there is a lack of knowledge and information concerning the behavior of their seismic response. Due to the life safety of masonry buildings under seismic effects are very essential, numerical modeling and analysis of the buildings are an important issue. Because of the insufficient seismic resistance on structural members such as jack arch slabs and masonry walls, numerical studies have become necessary to determine the level of the structural strength of the structures. The tensile strength of load-bearing walls in the buildings is lower whereas, the compressive strength is higher. In this way, tensile cracks occur at structural members due to insufficient tensile resistance. Therefore, the tensile stress locations in the structure are critical. The study focuses on the assessment of historical masonry buildings from the point of seismic resistance. The entire process is performed using a case study from a historical masonry building. In this study conducted in this respect, the existing situation of a historical building using numerical analyses were presented with the cross-disciplinary study of civil engineering and architecture. The linear elastic analysis is selected as an analysis method. The seismic parameters are determined based on the Turkish Earthquake Code (TBEC 2018). Consequently, the study is performed to determine the seismic-resistant of historical buildings within the scope of numerical analyses.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.
