This work presents a mathematical model describing the interactions between the cross-shore structure of small pelagic fish population an their exploitation by coastal and offshore fisheries. The complete model is a system of seven ODE’s governing three stocks of small pelagic fish population moving and growing between three zones. Two types of fishing fleets are inter-acting with the fish population, industrial boats, constrained to offshore area, and artisanal boats, operating from the shore. Two time scales were considered and we use (...) aggregation methods that allow us to reduce the dimension of the model and to obtain an aggregated model, which is a four dimension one. The analysis of the aggregated model is performed. We discuss the possible equilibriums and their meaning in terms of fishery management. An interesting equilibrium state can be obtained for which we can expect coexistence and a stable equilibrium state between fish stocks and fishing efforts. Some identification parameters are also given in the discussion part of the model. (shrink)

The feedback arrow extending from the response to the distal state in the lens model, together with Brunswik's dictum that the organism is a stabiliser of systems, implies a dynamic view of behaviour. This paper describes the main problems in the study of dynamic decision making: feedback delays and the feedback structure of the tasks. It also describes microworlds, a methodology for studying dynamic decision making in the laboratory. The results from experiments with microworlds show that subjects have problems compensating (...) for feedback delays and side effects. These results are discussed in terms of Brunswik's distinction between perception and thinking. (shrink)

BackgroundMoral distress is a phenomenon that can lead to an imbalance of the mind and body. There are many coping strategies to overcome the obstacles that lead the subject to this condition. Some coping strategies are capable of being achieved through the cultivation of moral resilience.AimThe aim is to identify the strategies of moral resilience in the nursing management of University Hospitals in Brazil.Research designThe research design is the qualitative study with discursive textual analysis.Participants and research context: 44 nurse managers (...) and nurses in leadership positions participated in a total of 30 University Hospitals in Brazil. Data were collected online, using a questionnaire with open questions.Ethical considerationsThe Ethics Committee approved the study. Participants received information about the research, agreed to respond to the questionnaire, and were guaranteed anonymity.FindingsPersonal adaptive strategies (intrapersonal and interpersonal) and organizational collaborative strategies (intrinsic and transformational management) emerged from this process. The intrapersonal strategies involved elements of rationality, flexibility, rebalancing practices, moral courage, and detachment. The interpersonal strategies addressed support networks, team involvement, and dialog. Organizational strategies dealt with actions which reorient ethical infrastructure, ethical education, and psychological protection, as well as fostering dialogical relationships, empowerment, and cooperation.ConclusionFrom the perspective of social historical construction, it is understood that developing personal and organizational strategies is essential to cultivating moral resilience.

Study of rationalism in Urdu literature.

Level statistics and nodal point distribution in a rectangular semiconductor quantum dot are studied for different degrees of spin-orbit coupling. The chaotic features occurring from the spin-orbit coupling have no classical counterpart. Using experimental values for GaSb/InAs/GaSb semiconductor quantum wells we find that level repulsion can lead to the semi-Poisson distribution for nearest level separations. Nodal lines and nodal points are also investigated. Comparison is made with nodal point distributions for fully chaotic states.

Is classical logic valid in empty domains? The aim of the paper is to show that for empty domains of individuals the thesis concerning the validity of classical logic cannot be consistently maintained. Taking the empty domain as an extension of a self-inconsistent property and making a distinction between logical and factual existence, it can be shown that in empty domains the assumption of the truth (resp.L-truth) of a universal statement leads to a paradox analogous to those of self-reflexivity.

Constitutional and judicial law-making is increasingly beginning to find its reflection not only in the Anglo-Saxon, but also in the Romano-Germanic legal family. However, the prerequisites for the use of this legal instrument are different, which determines the relevance of conducting a comparative analysis regarding the provision of such a mechanism in the USA and Kazakhstan. The purpose of the research is to identify common and distinctive features in the process of implementation of constitutional and judicial law-making in countries belonging (...) to different legal systems. The article uses the methods of analysis, synthesis, comparison, deduction and generalization. As a result, the specificity of ensuring the mechanism of constitutional law-making in the USA was expressed, taking into account various forms of law-making activity. It has been established that the development of constitutional provisions in the United States takes place with the help of the constitutional doctrines of the Supreme Court of the United States, which provide for the introduction of amendments to constitutional provisions without a formal procedure. As a result of the study of the experience of Kazakhstan, it was established that special priority was given to the role of precedent, in particular, the decision of the Supreme Court of the Republic of Kazakhstan. This is explained by the integrative nature of the Romano-Germanic legal system, which allows effective development of national legislation as a whole and its provisions. The obtained results can be used during the professional training of judges in the Republic of Kazakhstan. (shrink)

K. Satchidananda Murty (1924-2011) was a vociferous writer and an iconoclast. This volume is a collection of his unpublished writings. It includes Murty's views on the Veda, its meaning, relevance, and study, and shows the significance of the Vedāntic vision to the modern world. Murty elucidates the basic tenets of Advaita Vedānta and expounds the Advaitic doctrine of the relationships between Brahman and God, Brahman and the individual self, as well as between God and the world. In his writings, Murty (...) contrasts empirical knowledge with transcendental wisdom and surveys the history of Indian science and scientific views in ancient times. The book also includes Murty's musings on the scholar Śankara's philosophy, authorship and religious life. An important contribution to Indian philosophy, the volume will be of great interest to scholars, teachers and students of Hindu philosophy, Vedāntic philosophy, Advaita Vedanta, comparative philosophy, religious studies, and South Asian studies.

This chapter provides an introduction to higher-order metaphysics as well as to the contributions to this volume. We discuss five topics, corresponding to the five parts of this volume, and summarize the contributions to each part. First, we motivate the usefulness of higher-order quantification in metaphysics using a number of examples, and discuss the question of how such quantifiers should be interpreted. We provide a brief introduction to the most common forms of higher-order logics used in metaphysics, and indicate a (...) number of questions which can be raised in such systems using logical vocabulary alone. Using a further example, we return to applications of higher-order logics in metaphysics. We also mention key developments in the history of higher-order logic as it pertains to metaphysics. Finally, we mention certain arguments which have been raised against the use of higher-order logic, and some ways of responding to them. (shrink)

This monograph aims to mathematically codify the notion of "moral systems" and define a sensible distance between them. It consists of three parts, aimed at an audience with varying interests and mathematical backgrounds. The first part steers philosophical, formally defining moral systems and several related concepts. The second part studies black box algorithms, including questions of inference and metric construction. The third part explores the technical construction of metrics amongst conditional probability distributions.
