Dissolving the Dichotomies Between Online and Campus-Based Teaching: a Collective Response to The Manifesto for Teaching Online (Bayne et al. 2020)

This article is a collective response to the 2020 iteration of The Manifesto for Teaching Online. Originally published in 2011 as 20 simple but provocative statements, the aim was, and continues to be, to critically challenge the normalization of education as techno-corporate enterprise and the failure to properly account for digital methods in teaching in Higher Education. The 2020 Manifesto continues in the same critically provocative fashion, and, as the response collected here demonstrates, its publication could not be timelier. Though the Manifesto was written before the Covid-19 pandemic, many of the responses gathered here inevitably reflect on the experiences of moving to digital, distant, online teaching under unprecedented conditions. As these contributions reveal, the challenges were many and varied, ranging from the positive, breakthrough opportunities that digital learning offered to many students, including the disabled, to the problematic, such as poor digital networks and access, and simple digital poverty. Regardless of the nature of each response, taken together, what they show is that The Manifesto for Teaching Online offers welcome insights into and practical advice on how to teach online, and creatively confront the supremacy of face-to-face teaching

RECENT PROGRESS ON THE FACILITY UPGRADE FOR ACCELERATED RADIOACTIVE BEAMS AT TEXAS A&M *

The Cyclotron Institute at Texas A&amp;M University is<br />involved in an upgrade, one goal of which is to provide<br />radioactive ion beams accelerated to intermediate<br />energies by the K500 superconducting cyclotron. The old<br />88&rdquo; cyclotron, now the K150, has been refurbished to be<br />used as a driver and also to provide higher intensity, lowenergy,<br />primary beams for experiments. Two external ion<br />sources, an electron-cyclotron-resonance ion source<br />(ECRIS) and a multi-cusp negative ion source, have been<br />installed on a new axial line to inject beams into a<br />modified K150 central region. Acceleration of negative<br />ions of protons and deuterons with stripping for<br />extraction will be used in order to mitigate activation of<br />the K150. Beams from the K150 will be used to create<br />radioactive species via a light-ion guide and a heavy-ion<br />guide. Singly charged ions from either ion guide will be<br />transported to an ECRIS that is configured to capture<br />these ions and further ionize them. One charge-state from<br />this second ECRIS will be selected for subsequent<br />acceleration by the K500. Progress on the upgrade,<br />including the acceleration and extraction of both negative<br />and positive beams by the K150, is presented

Multilevel societies in new world primates? Flexibility may characterize the organization of Peruvian red uakaris (Cacajao calvus ucayalii)

Researchers have described multilevel societies with one-male, multifemale units (OMUs) forming within a larger group in several catarrhine species, but not in platyrhines. OMUs in multilevel societies are associated with extremely large group sizes, often with >100 individuals, and the only platyrhine genus that forms groups of this size is Cacajao. We review available evidence for multilevel organization and the formation of OMUs in groups of Cacajao, and test predictions for the frequency distribution patterns of male–male and male–female interindividual distances within groups of red-faced uakaris (Cacajao calvus ucayalii), comparing year-round data with those collected at the peak of the breeding season, when group cohesion may be more pronounced. Groups of Cacajao fission and fuse, forming subgroup sizes at frequencies consistent with an OMU organization. In Cacajao calvus ucayalii and Cacajao calvus calvus, bachelor groups are also observed, a characteristic of several catarrhine species that form OMUs. However, researchers have observed both multimale–multifemale groups and groups with a single male and multiple females in Cacajao calvus. The frequency distributions of interindividual distances for male–male and male–female dyads are consistent with an OMU-based organization, but alternative interpretations of these data are possible. The distribution of interindividual distances collected during the peak breeding season differed from those collected year-round, indicating seasonal changes in the spatial organization of Cacajao calvus ucayalii. We suggest a high degree of flexibility may characterize the social organization of Cacajao calvus ucayalii, which may form OMUs under certain conditions. Further studies with identifiable individuals, thus far not possible in Cacajao, are required to confirm the social organization.Publisher PDFPeer reviewe
