Abstract
The trend of rising income inequality in Germany since the mid-1990s is strongly amplified when considering income after housing expenditure. The income share of housing expenditure rose disproportionally for the bottom income quintile and fell for the top quintile. Factors contributing to these trends include declining relative costs of homeownership versus renting, changes in household structure, declining real incomes for low-income households and residential mobility towards larger cities. Younger cohorts spend more on housing and save less than older cohorts did at the same age, which will affect future wealth accumulation, particularly at the bottom of the income distribution.

Aim: The purpose of this review is to describe the use and definitions of the concepts of nurse-patient interaction and nurse-patient communication in nursing literature. Furthermore, empirical findings of nurse-patient communication research will be presented, and applied theories will be shown. Method: An integrative literature search was executed. The total number of relevant citations found was 97. The search results were reviewed, and key points were extracted in a standardized form. Extracts were then qualitatively summarized according to relevant aspects and categories for the review. Results: The relation of interaction and communication is not clearly defined in nursing literature. Often the terms are used interchangeably or synonymously, and a clear theoretical definition is avoided or rather implicit. Symbolic interactionism and classic sender-receiver models were by far the most referred to models. Compared to the use of theories of adjacent sciences, the use of original nursing theories related to communication is rather infrequent. The articles that try to clarify the relation of both concepts see communication as a special or subtype of interaction. Conclusion: The included citations all conclude that communication skills can be learned to a certain degree. Involvement of patients and their role in communication often is neglected by authors. Considering the mutual nature of communication, patients' share in conversation should be taken more into consideration than it has been until now. Nursing science has to integrate its own theories of nursing care with theories of communication and interaction from other scientific disciplines like sociology.

Zusammenfassung
Der Beitrag diskutiert Auswirkungen der Einführung des Sozialgesetzbuches II auf gesundheitlich beeinträchtigte Leistungsbezieher und die Inanspruchnahme von beruflichen Rehabilitationsleistungen. Es zeigt sich, dass einerseits die Ziele des SGB II mit Zielen des SGB IX in Teilen schwer vereinbar sind. Aufbauprozesse der neuen SGB II-Träger, vor allem im Jahr 2005, führten andererseits zu Aufgabenhierarchisierung und zur Konzentration auf finanzielle Leistungsgewährung. Das Ziel einer schnellen Vermittlung in Arbeit beeinflusst pudern Zugangsprozesse und trägt, neben anderen Faktoren, im Ergebnis einem deutlichen Rückgang der Eintritte in Maßnahmen der beruflichen Rehabilitation bei. So lassen sich in unterschiedlich starkem Maße Anzeichen einer Praxis herausarbeiten, die eine Inkongruenz zur gesetzgeberischen Intention deutlich machen.
