Modeling the IPv6 Internet AS-level Topology

To measure the IPv6 internet AS-level topology, a network topology discovery system, called Dolphin, was developed. By comparing the measurement result of Dolphin with that of CAIDA's Scamper, it was found that the IPv6 Internet at AS level, similar to other complex networks, is also scale-free but the exponent of its degree distribution is 1.2, which is much smaller than that of the IPv4 Internet and most other scale-free networks. In order to explain this feature of IPv6 Internet we argue that the degree exponent is a measure of uniformity of the degree distribution. Then, for the purpose on modeling the networks, we propose a new model based on the two major factors affecting the exponent of the EBA model. It breaks the lower bound of degree exponent which is 2 for most models. To verify the validity of this model, both theoretical and experimental analyses have been carried out. Finally, we demonstrate how this model can be successfully used to reproduce the topology of the IPv6 Internet.Comment: 15 pages, 5 figure

Navigating in the Landscape of Care: A Critical Reflection on Theory and Practise of Care and Ethics

The theory and practise of care is defined and enacted differently in different national as well as cultural contexts, illuminating how differently constructed the personal and societal structures in Europe are. A common trait is however that care work paid or non-paid, private or public is identified with women. To navigate in the landscape of care and ethics requires taking into account the constitutive relation between one’s identity, embodiment and position. The author suggests conceiving care as an existential condition of life demanded from all human beings. This will free care from the identification with women and pave a way towards a more gender equal and just society with less gender segregation in the labour market and at the arena of education

Treatment strategies and prognostic factors of patients with primary germ cell tumors in the mediastinum

Se presenta una paciente que fue intervenida quirúrgicamente por presentar una lesión tumoral a nivel del mediastino anterior, totalmente asintomática y descubierta, de forma incidental (incidentaloma), en el estudio preoperatorio por padecer litiasis vesicular. La tumoración resultó ser, histológicamente, un teratoma quístico maduro. La paciente evolucionó satisfactoriamente.It presents a patient who was surgery because of a tumor at the level of the anterior mediastinum, totally asymptomatic and uncovered, incidentally (incidentaloma), in the preoperative study due to vesicular lithiasis. The tumor turned out to be, histologically, a mature cystic teratoma. The patient evolved satisfactorily

Emergency department triage: an ethical analysis

<p>Abstract</p> <p>Background</p> <p>Emergency departments across the globe follow a triage system in order to cope with overcrowding. The intention behind triage is to improve the emergency care and to prioritize cases in terms of clinical urgency.</p> <p>Discussion</p> <p>In emergency department triage, medical care might lead to adverse consequences like delay in providing care, compromise in privacy and confidentiality, poor physician-patient communication, failing to provide the necessary care altogether, or even having to decide whose life to save when not everyone can be saved. These consequences challenge the ethical quality of emergency care. This article provides an ethical analysis of "routine" emergency department triage. The four principles of biomedical ethics - viz. respect for autonomy, beneficence, nonmaleficence and justice provide the starting point and help us to identify the ethical challenges of emergency department triage. However, they do not offer a <it>comprehensive </it>ethical view. To address the ethical issues of emergency department triage from a more comprehensive ethical view, the care ethics perspective offers additional insights.</p> <p>Summary</p> <p>We integrate the results from the analysis using four principles of biomedical ethics into care ethics perspective on triage and propose an integrated clinically and ethically based framework of emergency department triage planning, as seen from a comprehensive ethics perspective that incorporates both the principles-based and care-oriented approach.</p

Moments of Goodness: An Analysis of Ethical and Educational Dimensions of the Terror Attack on Utøya, Norway (July 22, 2011)

Published version of an article in the journal: Studies in Philosophy and Education. Also available from the publisher at: http://dx.doi.org/10.1007/s11217-014-9452-1The analysis is based on some moral experiences taking place during a terrorist attack on the Norwegian Labor Party’s youth camp on the island of Utøya (outside of Oslo) July 22, 2011, where 69 young people were killed and several seriously injured. After the attack many of the survivors told stories of how strangers spontaneous had helped and cared for each other. In the midst of the horror there occurred sudden “moments of goodness” or “points of light” that revealed hope for the persons involved, as well as for the society. The article examines these spontaneous moral practices in light of moral educational theory, as well as discusses the terrorists own way of thinking and acting. The spontaneous practices point toward another basis for a moral approach then a cognitive development tradition. The importance of community is underlined, as well as an interpersonal dimension. In the last section the fostering of moral and ethical thinking and acting is discussed in light of general education and the three functions of education proposed by Biesta (Beyond learning: democratic education for a human future. Paradigm Publishers, Boulder, 2010). It is suggested that moral education could contribute something to all of the three dimensions but based on the experiences from Utøya, there will be a particular emphasis on the subjectification function of education
