Anisotropic atomic motions in structural analysis by low energy electron diffraction

The structure of the √3 × √3 R30° overlayer formed by CO molecules adsorbed on a Ru(0001) was analyzed by low energy electron diffraction. Anisotropic atomic motions under the influence of thermal excitation were taken into account by adopting the concept of split positions. Apart from considerable improvement in the structural refinement this technique provides information about dynamic processes. In particular, the molecular axis of the CO molecules was found to be tilted on the average by (12±3° at 150 K, which is attributed to excitation of the bending mode vibration (i.e., frustrated translation)

This essay explores the author’s process of trying to understand how to responsibly forge a relationship with traditional song heritage given conditions of ethnocultural rupture. Weaving together Slovácko folk songs transcribed by the author’s great-grandfather, an archival recording of the author’s grandfather, audio/video documents of her own embodied performance, dreams, folk tales, and analysis, the piece meditates on the many facets of “living song” (živá píseň). The author explores her process of learning how to approach the life of song, and how songs might be cared for. The performance of practice-based research is posited as a means to confront and dismantle patriarchal white supremacy within one’s body and spirit, thereby making possible the recovery of exiled strands of self and the forging of ancestral connections

Living song : an intergenerational investigation of Moravian folk song

Throughout the first half of the 20th century, biologist/ethnomusicologist Vladimír Úlehla (1888-1947) transcribed hundreds of folk songs from Strážnice, his hometown in the rural region of Slovácko, which lies at the border of present-day Czech and Slovak Republics. For Úlehla, Slovácko songs were living organisms, intimately related to the landscape and carried through time by family clans. Some of his interlocutors were relatives. Others were relations forged by decades of friendship. Vladimír was my great-grandfather, and his monograph Živá píseň (Living Song, 1949) provided a means for me to enter into a musical-cultural heritage that was ruptured when my father escaped communist Czechoslovakia and entered North America as a refugee. Informed by song transcriptions, Vladimír’s ideas about living song, childhood experiences musicking with family members, and ethnographic fieldwork, this dissertation seeks to address the life of song, even when hybridity, rupture, and transplant figure into that inquiry. Through a networked, rhizomatic framework and mixed-methods approach, this research brings a number of theoretical, historical and methodological contexts to bear on addressing the living nature of song. Family oral history, interviews with musicians, and folk song poetics gesture towards a Slovácko cosmology that inscribes a world co-inhabited by humans, ancestral spirits, birds, trees, waters, mountains, and storms, all of which are conceived as animate and interrelated. Participant observation, my own research-creation and subsequent song-bartering (Bovin 1988) offer glimpses into the powerful role that songs play in connecting people with one another and with their ancestors. I describe how during fieldwork, the cultural hybridity of my performing body called many complex and painful histories into question and disrupted folk song’s alliance with cultural purity, which was especially provocative in an era of heightened xenophobia. Weaving together a consideration of the formal qualities of songs, their affectual, emotional power, and the historical/political contexts in which they appear, Slovácko songs emerge as agentive entities with which a human might collaborate in a variety of culturally-specific performance ecologies, thereby opening possibilities for ethical, anticolonial research practices and interpersonal encounters within a heterogeneous, multicultural society facing crises of social injustice, the COVID-19 pandemic, and impending climate catastrophe.Arts, Faculty ofMusic, School ofGraduat
