Technology and Ethics. A European Quest for Responsible Engineering, edited by B. Heriard Dubreuil and his team (University Lille) is in many regards an innovative publication. It is the first fully European contribution to the field of engineering ethics and the result of an intensive cooperation between ethicists and engineers from all the member countries of the European Union. The basic structure of the book is both the distinction and interaction between three levels of analysis: personal responsibility of engineers, the (...) institutional level (business organisations) and the impact of technology on society and culture. On the personal level, the book deals with problems such as the role of professional codes and the fact that engineers must cope with flexibility, shorter lines of decision and erosion of the boundaries between private and professional life. On the meso level, the book deals with different aspects of decision making in the context of business organizations, such as quality management, technology assessment procedures, business ethics committees etc... On the macro level, the authors focus on the power of technology. Together with the influences from other social, economic and political actors, the decisions of engineers change the world in a way which is of moral significance. (shrink)

We investigate two formalizations of Optimality Theory, a successful paradigm in linguistics.We first give an order-theoretic counterpart for the data and processinvolved in candidate evaluation.Basically, we represent each constraint as a function that assigns every candidate a degree of violation.As for the second formalization, we define (after Samek-Lodovici and Prince) constraints as operations that select the best candidates out of a set of candidates.We prove that these two formalizations are equivalent (accordingly, there is no loss of generality with using violation (...) marks and dispensing with them is only apparent).Importantly, we show that the second formalization is equivalent with a class of operations over sets of formulas in a given logical language.As a result, we prove that Optimality Theory can be characterized by certain cumulative logics.So, applying Optimality Theory is shown to be reasoning by the rules of cumulative logics.

Rationale, aims and objectives This randomized controlled trial was designed to evaluate the 2-year costs and effects of a proactive, public health nursing case management approach compared with a self-directed approach for 129 single parents (98% were mothers) on social assistance in a Canadian setting. A total of 43% of these parents had a major depressive disorder and 38% had two or three other health conditions at baseline. Methods Study participants were recruited over a 12 month period and randomized into (...) two groups: one receiving proactive public health nursing and one which did not. Results At 2 years, 69 single parents with 123 children receiving proactive public health nursing (compared with 60 parents with 91 children who did not receive public health nursing services) showed a slightly greater reduction in dysthymia and slightly higher social adjustment. There was no difference between the public health and control groups in total per parent annual cost of health and support services. However, costs were averted due to a 12% difference in non-use of social assistance in the previous 12 months for parents in the public health nursing group. This translates into an annual cost saving of $240 000 (Canadian) of costs averted within 1 year for every 100 parents. Conclusions In the context of a system of national health and social insurance, this study supports the fact that it is no more costly to proactively service this population of parents on social assistance.

Dogmatic Metaphysics and Tschirnhaus's M ethodology MARTIN SCHONFELD ACCORDING TO STANDARD COMMENTARIES, Tschirnhaus's main work, Medicina mentis, ~ supposedly furnished the methodological basis for the Leibnizian-Wolffian metaphysics. ~ Christian Wolff and his disciples, at any rate, preferred to think so. Wolff taught classes on Tschirnhaus and claimed that he had developed his own tenets on the basis of Tschirnhaus's ideas; Johann Christoph Gottsched praised the Medicina mentis as the basic methodology of the Wolffian enlightenment.3 Mirroring these views, W. Wundt and (...) H. J. de Vleeschauwer saw in Tschirnhaus the inventor of the "geometric method" adopted by the School Philosophers.4 According to M.

Trees architectural study shows gradients in the meristematic activity. This activity is described by the number of internodes per growth unit, which is considered as the output of a dynamic random process. Several species were observed, which led us to propose and then estimate some mathematical models. Computing the functioning of a tree in a given environment therefore involves finding the probability function of the meristems and following the evolution of the parameters of this law along the botanical gradients (order, (...) trend, acrotony) within its architecture.

In der vorliegenden Arbeit wird ein Begriffsrahmen entwickelt, in dem sich Gemeinsamkeiten und Unterschiede zwischen drei Arten von Kulturprodukten klar aufzeigen lassen: Dichtung, Mythos und Wissenschaft. Die allen drei Phänomenen gemeinsame Struktur erfassen wir in §II und §III mit dem Begriff eines Repräsentationssystems, welcher in Anlehnung an die formale Modelltheorie semiotische Vorstellungen mit einem Denken in Systemen zusammenbringt. Die relevanten Unterschiede werden durch Differenzierung (§IV) jenes Begriffs festgemacht, d.h. die drei Phänomene werden durch jeweils spezielle Arten von Repräsentationssystemen erfaßt (§V). (...) Unser spezielles Augenmerk gilt dabei dem Mythos (§I), der sich in letzter Zeit eines wachsenden Interesses -- oft außerhalb des etablierten Wissenschaftsbetriebs -- erfreut. Es zeigt sich, daß der Mythos eine Mittelstellung zwischen Dichtung und Wissenschaft einnimmt: als "Bindeglied" vermittelt er sowohl zwischen der rein begrifflichen Struktur der Phänomene "Dichtung" und "Wissenschaft" als auch zwischen deren Unterschieden in Methode und Wahrheitsanspruch (die in engem Zusammenhang mit der begrifflichen Struktur stehen). Der hier entwickelte begriffliche Rahmen soll in weiteren Untersuchungen als Grundlage zur Herausarbeitung von Unterschieden in der Methode und im Wahrheitsanspruch dienen, die sich aus unserem Ansatz in natürlicher Weise ergeben. Diese müssen jedoch aus Platzgründen einer weiteren Arbeit vorbehalten bleiben. (shrink)
