Though many experimental studies have documented that certain solution-phase additives can play a key role in the shape-selective synthesis of metal nanocrystals, the origins and mechanisms of this shape selectivity are still unclear.

Binary Nb-Hf alloys exhibit a wide bcc solid solution phase field at temperatures above the Hfα→ß transition (2023K) and a two phase bcc+hcp field at lower temperatures. The β solvus exhibits a small slope above about 1500K, suggesting the possible existence of a miscibility gap. An earlier investigation showed that two morphological forms of precipitate occur during the bcc→hcp transformation. The equilibrium morphology is rod-type with axes along <113> bcc. The crystallographic habit of the rod precipitate follows the Burgers relations: {110}||{0001}, <112> || <1010>. The earlier metastable form, transition α, occurs as thin discs with {100} habit. The {100} discs induce large strains in the matrix. Selected area diffraction examination of regions ∼2 microns in diameter containing many disc precipitates showed that, a diffuse intensity distribution whose symmetry resembled the distribution of equilibrium α Bragg spots was associated with the disc precipitate.

Abstract. Five overlapping eras or stages can be distinguished in the evolution of music therapy. The first one refers to the historical roots and ethnological sources that have influenced modern meta-theoretical perspectives and practices. The next stage marks the heterogeneous origins of modern music therapy in the 20th century that mirror psychological positions and novel clinical ideas about the healing power of music. The subsequent heyday of music therapeutic models and schools of thought yielded an enormous variety of concepts and methods such as Nordoff–Robbins music therapy, Orff music therapy, analytic music therapy, regulatory music therapy, guided imagery and music, sound work, etc. As music therapy gained in international importance, clinical applications required research on its therapeutic efficacy. According to standards of evidence-based medicine and with regard to clearly defined diagnoses, research on music therapeutic practice was the core of the fourth stage of evolution. The current stage is characterized by the emerging epistemological dissatisfaction with the paradigmatic reductionism of evidence-based medicine and by the strong will to discover the true healing nature of music. This trend has given birth to a wide spectrum of interdisciplinary hermeneutics for novel foundations of music therapy. Epigenetics, neuroplasticity, regulatory and chronobiological sciences, quantum physical philosophies, universal harmonies, spiritual and religious views, and the cultural anthropological phenomenon of esthetics and creativity have become guiding principles. This article should not be regarded as a historical treatise but rather as an attempt to identify theoretical landmarks in the evolution of modern music therapy and to elucidate the evolution of its spirit.

This comment briefly examines the history of entertainment research in media psychology and welcomes the conceptual innovations in the contribution by Oliver and Bartsch (this issue). Theoretical perspectives for improving and expanding the “appreciation” concept in entertainment psychology are outlined. These refer to more systematic links of appreciation to the psychology of mixed emotions, to positive psychology, and to the psychology of death and dying – in particular, to terror management theory. In addition, methodological challenges are discussed that entertainment research faces when appreciation and the experience of “meaning for life” need to be addressed in empirical studies of media enjoyment.
