The Disappearing State Corporate Income Tax

This paper examines alternative explanations for the decline over the past two decades in state corporate income taxes relative to the state economy. We employ a survey of state tax administrators, individual tax returns from Georgia and Utah, and panel data to explore the importance of tax policy, tax planning, and economic factors on the trend in state corporate taxes. We find that corporate tax planning and economic factors account for much of the relative decline and that state tax policy changes are important factors. However, federal tax changes had only a modest effect during this period. Working Paper 06-2

Resistance or resignation to welfare reform? The activist politics for and against social citizenship

Since 2008, mature welfare states have, to varying degrees, pursued a strategy of welfare reform that has reconfigured the dominant praxis of social citizenship. Drawing on qualitative data from two studies, this paper explores what bearing this has had on the political subjectivity of welfare claimants in the New Zealand context. The findings suggest welfare claimants engage in diverse political struggles for and against social citizenship to resist, reconfigure and resign themselves to the prevailing socio-political settlement. In light of this, conclusions are drawn about the insurgent politics of low-income social security claimants as political agents in the citizenship-making process

Accelerated Electrons in Cassiopeia A: An Explanation for the Hard X-ray Tail

We propose a model for the hard X-ray (> 10 keV) emission observed from the supernova remnant Cas A. Lower hybrid waves are generated in strong (mG) magnetic fields, generally believed to reside in this remnant, by shocks reflected from density inhomogeneities. These then accelerate electrons to energies of several tens of keV. Around 4% of the x-ray emitting plasma electrons need to be in this accelerated distribution, which extends up to electron velocities of order the electron Alfven speed, and is directled along magnetic field lines. Bremsstrahlung from these electrons produces the observed hard x-ray emission. Such waves and accelerated electrons have been observed in situ at Comet Halley, and we discuss the viability of the extrapolation from this case to the parameters relevant to Cas A.Comment: 20 pages, 3 figures, aasTeX502, accepted in Ap

Geologic controls on the recent evolution of oyster reefs in Apalachicola Bay and St. George Sound, Florida

This paper is not subject to U.S. copyright. The definitive version was published in Estuarine, Coastal and Shelf Science 88 (2010): 385-394, doi:10.1016/j.ecss.2010.04.019.Apalachicola Bay and St. George Sound contain the largest oyster fishery in Florida, and the growth and distribution of the numerous oyster reefs here are the combined product of modern estuarine conditions in the bay and its late Holocene evolution. Sidescan-sonar imagery, bathymetry, high-resolution seismic profiles, and sediment cores show that oyster beds occupy the crests of a series of shoals that range from 1 to 7 km in length, trend roughly north-south perpendicular to the long axes of the bay and sound, and are asymmetrical with steeper sides facing to the west. Surface sediment samples show that the oyster beds consist of shelly sand, while much of the remainder of the bay floor is covered by mud delivered by the Apalachicola River. The present oyster reefs rest on sandy delta systems that advanced southward across the region between 6400 and 4400 yr BP when sea level was 4–6 m lower than present. Oysters started to colonize the region around 5100 yr BP and became extensive by 1200 and 2400 yr BP. Since 1200 yr BP, their aerial extent has decreased due to burial of the edges of the reefs by the prodelta mud that continues to be supplied by the Apalachicola River. Oyster reefs that are still active are narrower than the original beds, have grown vertically, and become asymmetrical in cross-section. Their internal bedding indicates they have migrated westward, suggesting a net westerly transport of sediment in the bay.Funding for this research was provided by the NOAA Coastal Services Center

Non-take-up of benefits at the start of the COVID-19 pandemic

In this report, we look at the number of people eligible for UC but who didn't claim it, why they didn't claim, and their situation (funded by the Health Foundation)

"You're actually part of the team" : a qualitative study of a novel transitional role from medical student to doctor

Background Optimizing transitions from final year of medical school and into first post graduate year has important implications for students, patients and the health care system. Student experiences during novel transitional roles can provide insights into potential opportunities for final year curricula. We explored the experiences of medical students in a novel transitional role and their ability to continue learning whilst working as part of a medical team. Methods Novel transitional role for final year medical students were created in partnership by medical schools and state health departments in 2020 in response to the COVID-19 pandemic and the need for a medical surge workforce. Final year medical students from an undergraduate entry medical school were employed as Assistants in Medicine (AiMs) in urban and regional hospitals. A qualitative study with semi-structured interviews at two time points was used to obtain experiences of the role from 26 AiMs. Transcripts were analyzed using deductive thematic analysis with Activity theory as a conceptual lens. Results This unique role was defined by the objective of supporting the hospital team. Experiential learning opportunities in patient management were optimized when AiMs had opportunities to contribute meaningfully. Team structure and access to the key instrument, the electronic medical record, enabled participants to contribute meaningfully, whilst contractual arrangements and payments formalized the obligations to contribute. Conclusions The experiential nature of the role was facilitated by organizational factors. Structuring teams to involve a dedicated medical assistant position with specific duties and access to the electronic medical record sufficient to complete duties are key to successful transitional roles. Both should be considered when designing transitional roles as placements for final year medical students

Accelerated Electrons in Cassiopeia A: Thermal and Electromagnetic Effects

We consider in more detail a model previously proposed for the hard X-ray (>10 keV) emission observed from the supernova remnant Cas A, whereby electrons are accelerated by lower-hybrid waves and radiate bremsstrahlung. We consider both cold and thermal plasma limits of the modified two-stream instability that generates the lower-hybrid waves, and by studying time dependent ionization balance for various components of the Cas A ejecta and shocked circumstellar medium, find locations within the shell where one or other of the instabilities may occur. Either instability can be effective, with the cold plasma instability imposing fewer constraints on the shocked reflected ion population responsible for exciting the waves. The instability must be located in the ejecta shocked at the earliest times and therefore closest to the contact discontinuity where magnetic fields are expected to be the strongest. The energy deposited in this ejecta by collisions between accelerated and ambient electrons is broadly consistent with that required to reheat this ejecta to observed temperatures.Comment: 29 pages + 8 figures, accepted for publication by Ap

Reading with drama: relations between texts, readers and experiences

This article explores the intersections of drama and reading, specifically focusing on approaches that are situated within “drama in education.” Supported with a retrospective analysis, this article portrays the research, related practice and possible futures in drama education in relation to literacy and in particular to reading fiction as meaning making practice. This study is situated in a reassertion of the value of relational literacies through imaginative practices that dramatic modes generate and support. The article disrupts common misconceptions about the purposes and effects of drama in reading and establishes prominent research discourses and definitions across the history of drama and reading practices. By locating paradigmatic and practical opportunities in our analysis of contemporary research, we bring visibility to the intricacies of drama in education as a generative pedagogy in reading as relational meaning making work

Plasma structures observed in gas breakdown using a 1.5 MW, 110 GHz pulsed gyrotron

Regular two-dimensional plasma filamentary arrays have been observed in gas breakdown experiments using a pulsed 1.5 MW, 110 GHz gyrotron. The gyrotron Gaussian output beam is focused to an intensity of up to 4 MW/ cm2. The plasma filaments develop in an array with a spacing of about one quarter wavelength, elongated in the electric field direction. The array was imaged using photodiodes, a slow camera, which captures the entire breakdown event, and a fast camera with a 6 ns window. These diagnostics demonstrate the sequential development of the array propagating back toward the source. Gases studied included air, nitrogen, SF6, and helium at various pressures. A discrete plasma array structure is observed at high pressure, while a diffuse plasma is observed at lower pressure. The propagation speed of the ionization front for air and nitrogen at atmospheric pressure for 3 MW/ cm2 was found to be of the order of 10 km/s.open322
