  • We present a 1000 km transect of phase-sensitive radar measurements of ice thickness, basal reflection strength, basal melting and ice-column deformation across the Ross Ice Shelf (RIS). Measurements were gathered at varying intervals in austral summer between 2015 and 2020, connecting the grounding line with the distant ice shelf front. We identified changing basal reflection strengths revealing a variety of basal conditions influenced by ice flow and by ice–ocean interaction at the ice base. Reflection strength is lower across the central RIS, while strong reflections in the near-front and near-grounding line regions correspond with higher basal melt rates, up to 0.47 ± 0.02 m a−1 in the north. Melting from atmospherically warmed surface water extends 150–170 km south of the RIS front. Melt rates up to 0.29 ± 0.03 m a−1 and 0.15 ± 0.03 m a−1 are observed near the grounding lines of the Whillans and Kamb Ice Stream, respectively. Although troublesome to compare directly, our surface-based observations generally agree with the basal melt pattern provided by satellite-based methods but provide a distinctly smoother pattern. Our work delivers a precise measurement of basal melt rates across the RIS, a rare insight that also provides an early 21st-century baseline.

  • Objective

    Agricultural workers such as migrant and seasonal farmworkers are a population uniquely vulnerable to the negative effects of climate-related disasters. The primary aim of this study was to assess how counties in eastern North Carolina (NC) incorporated best practices related to agricultural workers in emergency preparedness planning.

    Methods

    The authors conducted a quantitative content analysis of 47 emergency preparedness plans from 41 eastern NC counties between November 2022 and March 2023. The research team developed a codebook based on recommended best practices from the Centers for Disease Control and Prevention, Farmworker Advocacy Network, Federal Emergency Management Agency, and National Center for Farmworker Health. Best practices included having materials in Spanish language, mapping vulnerable populations, and garnering input from agricultural workers.

    Results

    Of the 47 plans evaluated, most lacked inclusion of agricultural workers in emergency preparedness planning. Furthermore, plans demonstrated few relevant best practices that address agricultural workers’ specific challenges in preparation for and recovery from climate-related disasters.

    Conclusions

    Public emergency preparedness plans in eastern NC rarely include mention of recommended best practices related to agricultural workers. Local emergency preparedness officials should consider collaboration with advocacy groups, community health workers, and federal emergency management agencies to build disaster resilience.

    Texts and Intertexts in Archaic and Classical Greece

  • Summary

    The first section of this introduction sets the scene for the volume as a whole by briefly considering the history of intertextuality within modern classical scholarship, both Latin and Greek, and then highlighting the special methodological and historical challenges that attend on comparative approaches to early Greek literature. As scholars increasingly agree on the need to read early Greek literature in a comparative way, it is argued, this only makes more urgent the question of how best to do so. The second section of the introduction highlights some of the core methodological, historical, and literary preoccupations of this book by exploring in chronological order two contrastive and complementary case studies from early elegy, one from Tyrtaeus and one from Simonides. Rather than providing a set of definitive answers about how these texts relate to epic tradition and/or particular epics, this section aims to give a sense of the sort of questions at stake in the following chapters. The introduction then concludes by summarising each of those chapters and highlighting interconnections between them.

  • Summary

    As scholars look increasingly for the traces of intertextuality and allusion in early Greek poetry, Homer remains the prime focus of interest, and the relationship between the Iliad and Odyssey especially so. This chapter suggests that, though direct allusion between texts should not be ruled out a priori, an intertextual dynamic which stems from the traditionality of the texts is a more reliable and rewarding first interpretative step. The discussion reviews two examples which have served as important planks in the case that the Odyssey explicitly refers to the Iliad, and finds wanting the allusive arguments normally used to make that case, before suggesting a more methodologically and historically sound form of interaction. Interpretation, meaning, and appreciation all remain possible, and are indeed much richer in their appreciation of the poetry.

  • Encompassing the period from the earliest archaic epics down through classical Athenian drama, this is the first concerted, step-by-step examination of the development of allusive poetics in the early Greek world. Recent decades have seen a marked rise in intertextual approaches to early Greek literature; as scholars increasingly agree on the need to read these texts in a comparative way, this only makes all the more urgent the question of how best to do so. This volume brings together divergent scholarly voices to explore the state of the field and to point the way forward. All twelve chapters address themselves to a core set of fundamental questions: how do texts generate meaning by referring to other texts and how do the poetics of allusivity change over time and differ across genres? The result is a holistic study of a key dimension of literary experience.
