Entre el "deber" y el "derecho": patrimonio arqueológico y obligaciones sociales en Patagonia Argentina Among "duty" and "rights": Archaeological heritage and social obligations in Argentine  [cached]

Abstract: En a os recientes, los restos arqueológicos de varias provincias de la Patagonia han sido legislados bajo la categoría de "patrimonio cultural" de las mismas, regulándose su uso científico, cultural y, en ciertos casos, turístico. Sin embargo, más allá de los comportamientos reglados por el texto legal coexiste toda una serie de comportamientos y lazos sociales que se rigen bajo otras reglas o principios que trascienden el marco normativo. Motiva así, a este artículo, analizar los intercambios sociales que se entretejen por fuera del andamiaje institucional y jurídico alrededor de los bienes arqueológicos, específicamente del arte rupestre, en una ciudad de Patagonia. La importancia del análisis reside en el tipo de relaciones que se actualiza hoy alrededor de este patrimonio, el desplazamiento de sentidos que éstas impulsan sobre este bien y los efectos que generan en la gestión del mismo. El examen de las prestaciones y contraprestaciones, esto es, de las obligaciones mutuas que expresan, pretende servir como un ejemplo de la resignificación que en los últimos a os adquieren los bienes arqueológicos y, específicamente el arte rupestre en la Patagonia Argentina, así como de las complejidades que reviste su gestión. In recent years the archaeological remains from several Patagonian provinces were legislated under the category of "cultural heritage," regulating their scientific, cultural and, in some cases, touristic use. Nevertheless, beyond the behaviors regulated by the legal text an entire series of behaviors and social connections coexist that is governed by other rules or principles which transcend the normative framework. As such, the goal of this paper is to analyze the social exchanges that are woven together beyond the institutional and legal scaffolding erected around archaeological goods - specifically rock art - in a Patagonian city. The relevance of the analysis lies in the type of relationships that are now actualized around this heritage, the change of meanings of these artefacts that such relationships motivate and the effects they produce on the management of the archaeological heritage. An analysis of the exchange of services and of the mutual obligations that arise serves as an example of the new meanings acquired by archaeological goods - especially rock art in Argentine Patagonia - in recent years, as well as the complexities of its management.

Nisticò, G.;
Brazilian Journal of Physics , 2005, DOI: 10.1590/S0103-97332005000300020
Abstract: to perform a more transparent analysis of the problems raised by contrary inferences within consistent history approach to quantum theory, we extend the formalism of the conceptual basis. according to our analysis, the conceptual difficulties arising from contrary inferences are ruled out.

JIA Shu-wei,HE Cheng-yuan
Journal of Chongqing Normal University , 2012,
Abstract: This paper gives the concept of the contrary orthogonal matrix and studies its centrosymmetry, and obtains the following main results: the contrary orthogonal matrix is row column symmetric matrix and centrosymmetric matrix; cross the row anyway, the matrix transpose matrix and its transpose rows and columns transposed matrix is centrosymmetric matrix; cross the row anyway, rows of the matrix transpose inverse of a matrix of rows equal to its inverse transpose, the transpose column inverse of a matrix is equal to its inverse columns of the matrix transpose; its row transpose matrix transpose is equal to its transpose rows of the matrix transpose, its columns of transpose matrix is equal to its transpose matrix of columns.

Abstract: In the aftermath of SARS and with the spectre of a pandemic avian influenza, it is imperative that we (re)consider the obligations of HCPs for patients with severe infectious diseases, particularly diseases that pose risks to those providing care. It is of pressing importance that organizations representing HCPs give clear indication of what standard of care is expected of their members in the event of a pandemic. In this paper, we address the issue of special obligations of HCPs during an infectious disease outbreak. We argue that there is a pressing need to clarify the rights and responsibilities of HCPs in the current context of pandemic flu preparedness, and that these rights and responsibilities ought to be codified in professional codes of ethics. Finally, we present a brief historical accounting of the treatment of the duty to care in professional health care codes of ethics.An honest and critical examination of the role of HCPs during communicable disease outbreaks is needed in order to provide guidelines regarding professional rights and responsibilities, as well as ethical duties and obligations. With this paper, we hope to open the social dialogue and advance the public debate on this increasingly urgent issue.In 2003, the world witnessed the spread of a novel and deadly virus, namely SARS CoV. The health care workers (HCWs) and hospital systems that bore the brunt of the SARS outbreak continue to struggle with the aftermath of the crisis. Indeed, HCWs – both in clinical care and in public health – were severely tested by SARS. Unprecedented demands were placed on their skills and expertise, and their personal commitment to their profession was severely tried. Many were exposed to serious risk of morbidity and mortality; indeed, approximately 30% of reported cases were among HCWs, some of whom died from the infection [1].As a number of commentators have noted, SARS exposed the vulnerabilities of our current health care systems and governance structures [2

Abstract: Commercial professionals have some obligations under the law, aimed both at defending public interests and the interests of third parties who enter into contracts with traders and commercial credit, and at defending the interests of professionals themselves, by creating an appropriate legal framework for the activities they perform. The main obligations of traders are the following: fulfilling Trade Register advertising formalities; exercising trade within the limits of legitimate competition; and the organization and bookkeeping of commercial companies. This paper aims at elaborating on the three listed obligations, mainly referring to commercial professionals, as they carry out professional activities that are centered on obtaining profit.
Discourse Obligations in Dialogue Processing  [PDF]
David R. Traum,James F. Allen
Computer Science , 1994,
Abstract: We show that in modeling social interaction, particularly dialogue, the attitude of obligation can be a useful adjunct to the popularly considered attitudes of belief, goal, and intention and their mutual and shared counterparts. In particular, we show how discourse obligations can be used to account in a natural manner for the connection between a question and its answer in dialogue and how obligations can be used along with other parts of the discourse context to extend the coverage of a dialogue system.
