Governance and Capacity Building in German and Austrian Public Health Since the 1950s
Horst Noack
Public Health Reviews , 2011,
Abstract: The German speaking countries (Germany and Austria) have a strong tradition of universal health insurance since the late 19th century. Germany was one of the leading countries in “social hygiene as health science”, an interdisciplinary field of academic work, health policy and practice, providing a comprehensive scientific basis both for professional education and training in the new academies for social hygiene, the schools of public health in the 1920s, and also for a rapidly growing network of municipal public health services. Public health in Austria at that time was less advanced. There was a rupture in the field of public health in these countries as the Nazi regime and World War II destroyed almost all of the human resources, the scientific basis and the institutional infrastructure required for advancement. In the postwar period Germany was divided with separate social and health systems in East and West Germany until reunification in 1990. Meanwhile, Austria became a democratic federal republic developing a social welfare policy on the basis of a successful economy. Whereas Germany set up national programmes to support the development of a new public health, Austria established a health promotion fund. As a result, there has been more growth in the public health community in Germany than in Austria. However, in both countries strong efforts to strengthen the educational base will be needed to address the complex issues facing public health in the 21st century. For example, health expenditures in Germany and Austria are among the highest in the European Union, but health systems indicators such as healthy life years show values below the European average. The challenge to renew the highly fragmented systems of health/disease care and improve the social determinants of population health underline the need for strengthening public health structures and national policy in the two German speaking countries. Development of the scientific community is underway but has not yet reached the levels of the outstanding achievements of the late 19th and early 20th centuries.
A idéia de identidade sob uma perspectiva semiótica
Juliane Noack
Galáxia , 2008,
Abstract: O tema do artigo é o conceito de identidade. O ponto de partida é a observa o de que as idéias de unidade, coerência e continuidade, enquanto constituintes do conceito de identidade, parecem perder o seu poder explicativo atualmente, na assim chamada pós-modernidade. O ideal de um EU uno e total levou a muitos debates e fez perguntar sobre se se deveria abdicar do conceito de identidade. O presente artigo pretende contribuir com esse debate, apresentando algumas reflex es sobre a idéia de identidade desde a perspectiva da Semiótica. Palavras-chave: identidade; semiótica; semiose; identidade como signo Abstract The notion of identity from the standpoint of semiotics - The subject of this article is the concept of identity. The starting point is the observation that the ideas of unity, coherence and continuity, which constitute the concept of identity, appear to be losing their explanatory power in so-called postmodernity. The ideal of a unique and complete "I" has led to heated debate about whether the concept of identity should be abandoned. This article aims to contribute to this debate, offering reflections about the concept of identity from the perspective of Semiotics and about how this perspective can enrich both the concept of identity and identity as such. Keywords: identity; semiotic; semiosis; identity as a sign

Vormoderne Geschlechterkonzepte Pre-Modern Gender Concepts
Karoline Noack
querelles-net , 2007,
Abstract: Zum Selbstverst ndnis der Geschlechterforschung geh rt es, ein differenzierteres Geschichtsbild zu konstruieren. Der vorliegende interdisziplin re Sammelband leistet dazu einen Beitrag. Es werden die vielf ltigen Diskurse über Geschlecht in Europa in der Zeit des übergangs zur Neuzeit diskutiert. Diese unterscheiden sich deutlich von dem seit der Mitte des 18. Jahrhunderts dominierenden Konzept des Geschlechterdualismus. Für den untersuchten Zeitraum ist ein Pluralismus von Geschlechter-Diskursen zu beobachten, die nebeneinander existieren, sich miteinander verbinden oder einander überschneiden k nnen. Part of the self-conception of gender research is the construction of a differentiated image of history. The interdisciplinary collected volume at hand contributes to this project. It discusses the diverse European discourses on gender in the transition to the modern era. These are noticeably different than the gender dualism propagated since the mid-18th century. Instead, a pluralism of gender discourses can be identified, which can exist alongside one another, be related to one another, or overlap.
Modularity clustering is force-directed layout
Andreas Noack
Computer Science , 2008, DOI: 10.1103/PhysRevE.79.026102
Abstract: Two natural and widely used representations for the community structure of networks are clusterings, which partition the vertex set into disjoint subsets, and layouts, which assign the vertices to positions in a metric space. This paper unifies prominent characterizations of layout quality and clustering quality, by showing that energy models of pairwise attraction and repulsion subsume Newman and Girvan's modularity measure. Layouts with optimal energy are relaxations of, and are thus consistent with, clusterings with optimal modularity, which is of practical relevance because both representations are complementary and often used together.
Dynamic Threshold Cryptosystem without Group Manager
Andreas Noack,Stefan Spitz
Network Protocols and Algorithms , 2009,
Abstract: In dynamic networks with flexible memberships, group signatures and distributed signatures are an important problem. Dynamic threshold cryptosystems are best suited to realize distributed signatures in dynamic (e.g. ad-hoc) networks. Without a group manager or a trusted third party even more flexible scenarios can be realized. Gennaro et al. [1] showed, it is possible to dynamically increase the size of the signer group, without altering the public key. We extend this idea by removing members from the group, also without changing the public key. This is an important feature for dynamic groups, since it is very common, e.g. in ad-hoc networks that members leave a group.Gennaro et al. used RSA and bi-variate polynomials for their scheme. In contrast, we developed a DL-based scheme that uses ideas from the field of proactive secret sharing (PSS). One advantage of our scheme is the possibility to use elliptic curve cryptography and thereby decrease the communication and computation complexity through a smaller security parameter.Our proposal is an efficient threshold cryptosystem that is able to adapt the group size in both directions. Since it is not possible to realize a non-interactive scheme with the ability to remove members (while the public key stays unchanged), we realized an interactive scheme whose communication efficiency is highly optimized to compete with non-interactive schemes. Our contribution holds against passive and active information theoretic adversaries.

Concentrations and chemical speciation of particulate matter in two Moroccan cities; Meknes and Kenitra
M. Tahri,Y. Noack
Journal of Environmental Science and Water Resources , 2012,
Abstract: An assessment of air quality in two Moroccan cities (Meknes and Kenitra) was performed by determining the elemental composition of particulate matter (fine and coarse) in a sampling campaign from June 2007 to May 2008 for Kenitra city and from March 2007 to April 2008 for Meknes city. The chemical composition of the collected samples was determined using Atomic Absorption Spectroscopy (AAS), Total Reflection X-Ray Fluorescence (TXRF) and Inductively Coupled Plasma Atomic Absorption Spectroscopy (ICP-AES). The results, for the both cities, show the highest concentrations of particulate matter in summer and the lowest in winter, particularly for coarse fractions. Furthermore, the fine/coarse ratios, for both cities, were in the most case lower than 0.5 indicating the importance of soil dusts and resuspension of deposited soil particles. The major emission sources identified in these two cities were traffic, soil dusts and resuspension of deposited particles.
DMRG study of ferromagnetism in a one-dimensional Hubbard model
S. Daul,R. Noack
Physics , 1996, DOI: 10.1007/s002570050376
Abstract: The one dimensional Hubbard model with nearest and (negative) next-nearest neighbour hopping has been studied with the density-matrix renormalization group (DMRG) method. A large region of ferromagnetism has been found for finite density and finite on-site interaction.
