Social scientists are being called upon more and more to study training for the various professions and to consult with those who make policy with reference to it. The following pages suggest a general frame of reference for such study. They were written for several people, both medical educators and social scientists, who were thinking of embarking on a modest study tracing the course of students through the maze of a particular medical school. There resulted a daylong discussion which was of great value in planning the study. It was more like a prolonged group interview than a formal discussion. While the ideas refer specifically to medicine, they implicitly refer to other professions as well.

Helping theories are discussed within the general frame of reference of Christian beliefs and the impact they may have on the spiritual healing of persons with disabilities or chronic illnesses. Each helping theory is summarized, then related to generally accepted ideas about Christian beliefs and their relationship to healing and rehabilitation. Spirituality can be seen as a potential source of help for persons who experience a chronic physical problem if at least minimally nurtured by the professional worker in rehabilitation.

Institutional theory is an important framework for various research fields. It gives a general frame of reference as to what constitutes an institution and what are the factors that affect it. However, the theory requires more than a general frame of reference because in today’s world the characteristics of the organizations are changing with the change in factors related as well as unrelated to the processes of organization. In this background, the paper attempts to provide a brief historical overview of institutions, institutionalisation, differences among institutions and institutional environment to unveil the development of institutional theory. It also looks at the application of institutional theory in the context of multinational enterprises. The findings indicate that emphasis of institutional theory has shifted from generalized system of social belief to appropriate means to become legitimate with the pressures.

Electron microscopy of replicating intermediates has been quite useful in understanding the mechanism of DNA replication in DNA molecules of bacteriophage, mitochondria and plasmids. The use of partial denaturation mapping has made the tool more powerful by providing a frame of reference by which the position of the replicating forks in bacteriophage DNA can be determined on the circular replicating molecules. This provided an easy means to find the origin and direction of replication in λ and P2 phage DNA molecules. DNA of temperate E. coli phage 186 was found to have an unique denaturation map and encouraged us to look into its mode of replication.

Zusammenfassung: Das I/E-Modell (“Internal/External Frame of Reference Model”) von Marsh (1986) postuliert, dass Schülerinnen und Schüler dimensionale Vergleiche der eigenen Leistungen in einem Fach mit den Leistungen in einem anderen Fach anstellen. Diese Vergleiche führen dazu, dass z. B. Schüler mit guten Leistungen in Mathematik ihre verbalen Fähigkeiten niedriger einschätzen. Gegenstand dieser Untersuchung mit N = 1114 Probanden ist die Frage, ob die Überzeugungen von Personen zum Zusammenhang von mathematischer und verbaler Begabung die Effekte dimensionaler Vergleiche moderieren. Analysen zeigten die Bedeutung der Begabungsüberzeugungen der Schülerinnen und Schüler: Negative Zusammenhänge zwischen den Fachleistungen in einem Fach und dem akademischen Selbstkonzept in einem anderen Fach ergaben sich insbesondere für Personen, die annehmen, dass Begabung domänenspezifisch ist, man also entweder mathematisch oder sprachlich begabt ist. Für Schüler mit eher wenig spezifischer Begabungsüberzeugung ergaben sich geringere Effekte dimensionaler Vergleiche.

The studies reported here focus on similarities and dissimilarities between the terminal value hierarchies ( Rokeach, 1973 ) ascribed to different groups ( Schwartz & Struch, 1990 ). In Study 1, n = 65 East Germans and n = 110 West Germans mutually assess the respective ingroup and outgroup. In this intra-German comparison the West Germans, with a mean intraindividual correlation of rho = 0.609, perceive a significantly greater East-West similarity between the group-related value hierarchies than the East Germans, with a mean rho = 0.400. Study 2 gives East German subjects either a Swiss (n = 58) or Polish (n = 59) frame of reference in the comparison between the categories German and East German. Whereas the Swiss frame of reference should arouse a need for uniqueness, the Polish frame of reference should arouse a need for similarity. In accordance with expectations, the Swiss frame of reference significantly reduces the correlative similarity between German and East German from a mean rho = 0.703 in a control group (n = 59) to a mean rho = 0.518 in the experimental group. Contrary to expectations, the Polish frame of reference does not lead to an increase in perceived similarity (mean rho = 0.712).

Zusammenfassung: Im Rahmen der Genese schulischer Selbstkonzepte postuliert das “Internal/External Frame of Reference”-Modell (I/E-M, Marsh, 1986 ) zwei (gegenläufige) Vergleichsprozesse: Neben sozialen Vergleichen spielen auch dimensionale Vergleiche (Leistungen in verschiedenen Fächern werden einander gegenübergestellt) eine Rolle. Diese sollen zu Kontrasteffekten führen, d. h. zu negativen Pfaden der Leistung in einem Fach (z. B. Mathematik) auf das Selbstkonzept in einem anderen Fach (z. B. Deutsch). Empirische Untersuchungen konzentrierten sich bislang hauptsächlich auf Mathematik und (Mutter-)Sprache. An N = 1632 Gymnasiasten haben wir das I/E-M strukturgleichungsbasiert für zwei sprachliche (Deutsch, Englisch), zwei naturwissenschaftliche (Physik, Mathematik) und zwei nicht eindeutig einer Domäne zugehörige Fächer (Geschichte, Biologie) überprüft. Neben Kontrasteffekten traten auch Assimilationseffekte (positive Pfade der Leistung in einem Fach auf das Selbstkonzept in einem anderen Fach) auf. Zukünftig müsste präzisiert werden, welche Faktoren das Ergebnis dimensionaler Vergleiche (Assimilation oder Kontrast) moderieren.

Progress in surgical technology and in postoperative therapy has remarkably increased life expectation after heart transplantation. Nevertheless, patients still show a resistance to resume a normal life after transplantation, for example, to return to work. In this study we assume that after surgery patients become risk averse because they achieve a positive frame of reference. Because of this propensity toward risk aversion, they withhold from engaging in behavior that their physical condition would allow them in principle. Coherent with this assumption we found that compared to the medical team patients overestimate the degree of risk for routine activities. The study also showed that the representation of risk by the patients could be captured by a dreadfulness factor and a voluntariness factor. Patients' risk judgments were strongly and specifically predicted by the perceived degree of dreadfulness of the activity and, to a lesser extent, by the perceived knowledge of the consequences. Implications for patient-physician communication were explored.
