Review: A Working Model For Contingent Faculty, Courtney L. Werner Jan 2024

Review: A Working Model For Contingent Faculty, Courtney L. Werner

The Writing Center Journal

In his book A Working Model for Contingent Faculty, Robert Samuels presents multiple ideas for helping contingent faculty organize to gain equity on campus: in their careers, working conditions, and pay. Samuels critiques current prominent, negative discourse on contingent faculty, offering instead ways to emphasize contingent faculty’s diverse and positive experiences and opportunities. I offer additional insights spurred from Samuels’s ideas, including connecting with student government and finding ways to make writing center work and research more public and apparent to institutional stakeholders (e.g., students, faculty, donors, administrators, boards/trustees).

Entrepreneurship As Collective Action: The Next Frontier., Cyrine Ben-Hafaïedh, Claire Champenois, Thomas M. Cooney, Leon Schjoedt Jan 2024

Entrepreneurship As Collective Action: The Next Frontier., Cyrine Ben-Hafaïedh, Claire Champenois, Thomas M. Cooney, Leon Schjoedt

Articles

Collective action in entrepreneurship is lacking in the extant literature. Despite entrepreneurship research progressively moves away from the focus of a lone heroic entrepreneur, scholars have yet to absorb the full potential of entrepreneurship as collective action. Also missing is a collective stance on key entrepreneurship concepts such as opportunity discovery or construction and entrepreneurial agency. Accordingly, this article reviews and critiques five articles that constitute this Special Issue seeking to establish ‘entrepreneurship as collective action’ as the next frontier of entrepreneurship theory development. The articles in this Special Issue each investigate a specific instance of collective action in entrepreneurship. …

Articles

The majority of available climate data in global digital archives consist of data only from the 1940s or 1950s onwards, and many of these series have gaps and/or are available for only a subset of the variables which were actually observed. However, there exist billions of historical weather observations from the 1700s, 1800s, and early 1900s that are still in hard‐copy form and are at risk of being lost forever due to deterioration. An assessment of changes in climate extremes in several IPCC regions was not possible in IPCC AR6 WGI owing, in many cases, to the lack of available …

Probing A Neural Unreliability Account Of Auditory Sensory Processing Atypicalities In Rett Syndrome, Tufikameni Brima, Shlomit Beker, Kevin D. Prinsloo, John Butler, Aleksandra Djukic, Edward G. Freedman, Sophie Molholm, John J. Foxe

Articles

Background: In the search for objective tools to quantify neural function in Rett Syndrome (RTT), which are crucial in the evaluation of therapeutic efficacy in clinical trials, recordings of sensory-perceptual functioning using event-related potential (ERP) approaches have emerged as potentially powerful tools. Considerable work points to highly anomalous auditory evoked potentials (AEPs) in RTT. However, an assumption of the typical signal-averaging method used to derive these measures is “stationarity” of the underlying responses – i.e. neural responses to each input are highly stereotyped. An alternate possibility is that responses to repeated stimuli are highly variable in RTT. If so, this …

Hamiltonian Models For The Propagation Of Long Gravity Waves, Higher-Order Kdv-Type Equations And Integrability, Rossen Ivanov Jan 2024

Hamiltonian Models For The Propagation Of Long Gravity Waves, Higher-Order Kdv-Type Equations And Integrability, Rossen Ivanov

Book chapter/book

A single incompressible, inviscid, irrotational fluid medium bounded above by a free surface is considered. The Hamiltonian of the system is expressed in terms of the so-called Dirichlet-Neumann operators. The equations for the surface waves are presented in Hamiltonian form. Specific scaling of the variables is selected which leads to a KdV approximation with higher order nonlinearities and dispersion (higher-order KdV-type equation, or HKdV). The HKdV is related to the known integrable PDEs with an explicit nonlinear and nonlocal transformation.

Sic Addition To A Dual Phase High Entropy Ultra-High Temperature Ceramic, Rubia Hassan, William G. Fahrenholtz, Kantesh Balani, Gregory E. Hilmas, Jeremy Watts

Materials Science and Engineering Faculty Research & Creative Works

Dual phase (Hf,Ta,Ti,W,Zr)B2-(Hf,Ta,Ti,W,Zr)C high entropy ultra-high temperature ceramics were processed from commercial diboride and carbide powders with and without SiC additions. A 30-min hold at a maximum temperature of 1850 °C in spark plasma sintering resulted in a relative density of ∼95 %, which increased to ∼100 % with the addition of 7.5 wt.% SiC. The compositions did not reach chemical equilibrium under the given sintering conditions resulting in an inhomogeneous distribution of transition metals in both the boride and carbide phases. The addition of SiC improved densification by inhibiting grain growth, which reduced the grain size from 9.0 ± …
