We develop a molecular-statistical theory of the smectic-A-smectic-C transition which is described as a transition of the order-disorder type. The theory is based on a general expansion of the effective interaction potential and employs a complete set of orientational order parameters. All the order parameters of the smectic-C phase including the tilt angle are calculated numerically as functions of temperature for a number of systems which correspond to different transition scenario. The effective interaction potential and the parameters of the transition are also calculated for specific molecular models based on electrostatic and induction interaction between molecular dipoles. The theory successfully reproduces the main properties of both conventional and so-called ``de Vries-type'' smectic liquid crystals, clarifies the origin of the anomalously weak layer contraction and describes the tricritical behavior at the smectic-A-smectic-C transition. The ``de Vries behavior,'' i.e., anomalously weak layer contraction is also obtained for a particular molecular model based on interaction between longitudinal molecular dipoles. A simple phenomenological model is presented enabling one to obtain explicit expressions for the layer spacing and the tilt angle which are used to fit the experimental data for a number of materials.

The symmetry of boundaries between ferroelectric, ferroelastic, and antiphase domains is a key element for a theoretical understanding of their properties. Here, we derive this symmetry from their organic relation to the symmetry of the primary transition order parameters. The domain wall symmetries are shown to coincide with directions of the order-parameter n-dimensional vector space, corresponding to sum of the vectors associated with adjacent domain states. This property is illustrated by the determination of the maximal symmetries of domain walls in BaTiO3, LaAlO3, SrTiO3, and Gd2(MoO4)3. Besides, the domain pattern in YMnO3 is interpreted as resulting from an annihilation-creation process, the annihilation of the antiphase domain walls creating six ferroelectric domain walls merging at a single point.

In this short note, we aim at a qualitative framework for modeling multivariate risk. To this extent, we consider completely distributive lattices as underlying universes, and make use of lattice functions to formalize the notion of risk measure. Several properties of risk measures are translated into this general setting, and used to provide axiomatic characterizations. Moreover, a notion of quantile of a lattice-valued random variable is proposed, which is shown to retain several desirable properties of its real-valued counterpart. [less ▲]

The paper emphasizes the importance of informal diagnostic procedures in routine paediatric and medical school entry check-ups (Kindervorsorge- und Einschulungsuntersuchungen) from the perspective of cultural analysis. Analysing the ethnographic data we demonstrate how diagnostic knowledge is built up in the course of interaction between paediatrician, parent, and child and which effects appear. The empirical analysis focuses on the paediatrician’s investigation into the child habits of watching television. This informal element of the physician’s diagnosis is specifically suitable to show how the paediatrician assesses the family’s lifestyle and its educational potential and how he uses this information to diagnose the need for prevention. We will argue that the interactive transformation of the focus of medical observation and treatment from “children” to “parents and children” – that means to the relationship between generations –, points out the dependency on the context and institutional logic in constructing diagnostic knowledge regarding developmental processes of children. It is shown as well in which way societal expectations on the generational relations in families are shaped in these preventive examinations of development. [less ▲]
