Perspectives on emergent wind band literature: Understanding the views of band directors in high school instrumental settings

Directors of school concert bands continue to program new and emergent works alongside pieces considered to be part of the core and traditional repertoire. The purpose of this dissertation was to discover what criteria directors consider important in their review of new and emergent concert band works for use in rehearsal and performance. A secondary objective examined if director experience and educational background influenced the evaluation of this music used in high school instrumental settings. In order to evaluate this recent repertoire, the Concert Band Repertoire Evaluation Criteria (CBREC) was developed by the researcher, and reviewed by a panel of collegiate directors. The review of the CBREC revealed it to be a reliable tool for the purposes of the study. An independent panel of experts in concert band repertoire selected three works to be reviewed by participants. Invited participants comprised band directors who hold membership in an international band fraternity. The teaching responsibilities of these directors included conducting concert bands at American senior high schools. Participant directors rated each work using the CBREC after viewing an image of the music score and listening to an audio recording of the piece. The participant directors had the option of rating their familiarity with each piece used and answering three open-ended questions regarding repertoire selection. Data collected from the participants indicated favorable mean ratings for the works used in the study. When the participant data were analyzed in sub-groups, several statistically significant findings were reported. Sub-groups including older directors, directors teaching only one ensemble, and directors who answered open-ended questions in the study demonstrated more stability in their ratings of the repertoire used in the study than did younger directors, directors teaching multiple ensembles, and directors who did not respond to open-ended questions. Results suggested participant directors reached a consensus regarding several aspects of the pieces used in the study, indicated by the CBREC Ratings and open-ended comments. The correlational analysis of CBREC Items demonstrated that directors are considering multiple aspects of a work during the evaluation process. Data supported that melodic material, pedagogical use, as well as timbre and orchestration influence how this group of directors estimate the longevity of new concert band works

Data from: The role of inbreeding depression and mating system in the evolution of heterostyly

We investigated the role of morph-based differences in the expression of inbreeding depression in loss of the mid-styled morph from populations of tristylous Oxalis alpina as proposed by theoretical analyses. The extent of self-compatibility of reproductive morphs, the degree of self-fertilization, and the magnitude of inbreeding depression were investigated in three populations of O. alpina differing in their tristylous incompatibility relationships. All three populations exhibited significant inbreeding depression. In two populations with highly modified tristylous incompatibility, manifested as increased reciprocal compatibility between short- and long-styled morphs, substantial self-compatibility and self-fertilization of mid-styled morphs was detected, and expected to result in expression of inbreeding depression in the progeny of mid-styled morphs in the natural populations. In contrast, significant self-fertility of the mid-styled morph was absent from the population with typical tristylous incompatibility, and no self-fertilization could be detected. Although self-fertilization and expression of inbreeding depression should result in selection against the mid-styled morph in the later stages of the transition from tristyly to distyly, in O. alpina selection against the mid-styled morph in the early phases of the evolution of distyly is likely due to genic selection against mid alleles associated with modified tristylous incompatibility, rather than expression of inbreeding depression
