Newspaper Theft, Self-Preservation and the Dimensions of Censorship

One of the most common yet understudied means of suppressing free expression on college and university campuses is the theft of freely-distributed student publications, particularly newspapers. This study examines news accounts of nearly 300 newspaper theft incidents at colleges and universities between 1995 and 2008 in order to identify the manifestations and consequences of this peculiar form of censorship, and to augment existing research on censorship and tolerance by looking, not at what people say about free expression, but at what they do when they have the power of censorship in their own hands. Among the key findings is that men commit nearly 70% of newspaper thefts, which is inconsistent with much of the existing research on censorship and gender, and that those who censor college newspapers are far more concerned with their own self-preservation than with shaping public dialog on controversial social or political issues

Madhouse Psychiatry and Politics in Cuban History

On the outskirts of Havana lies Mazorra, an asylum known to—and at times feared by—ordinary Cubans for over a century. Since its founding in 1857, the island\u27s first psychiatric hospital has been an object of persistent political attention. Drawing on hospital documents and government records, as well as the popular press, photographs, and oral histories, Dr. Jennifer L. Lambe charts the connections between the inner workings of this notorious institution and the highest echelons of Cuban politics. Across the sweep of modern Cuban history, she finds, Mazorra has served as both laboratory and microcosm of the Cuban state: the asylum is an icon of its ignominious colonial and neocolonial past and a crucible of its republican and revolutionary futures. Dr. Jennifer L. Lambe is Assistant Professor of Latin American and Caribbean History at Brown University. She earned her Ph.D. in Latin American and Caribbean History at Yale University and her B.A. in Gender Studies and History at Brown University. Her work has received support from the American Council of Learned Societies, the Andrew W. Mellon Foundation, the Coordinating Council for Women in History, and the Cuban Heritage Collection of the University of Miami Libraries. Dr. Lambe is coeditor of the volume New Histories of the Cuban Revolution, currently under review by Duke University Press.https://digitalcommons.fiu.edu/cri_events/1333/thumbnail.jp

Comparison maps for relatively free resolutions

Let Λ be a commutative ring, A an augmented differential graded algebra over Λ (briefly, DGA-algebra) and X be a relatively free resolution of Λ over A. The standard bar resolution of Λ over A, denoted by B(A), provides an example of a resolution of this kind. The comparison theorem gives inductive formulae f : B(A)→X and g : X→B(A) termed comparison maps. In case that fg=1 X and A is connected, we show that X is endowed a A  ∞ -tensor product structure. In case that A is in addition commutative then (X,μ X ) is shown to be a commutative DGA-algebra with the product μ X =f*(g⊗g) (* is the shuffle product in B(A)). Furthermore, f and g are algebra maps. We give an example in order to illustrate the main results of this paper

Strain-stiffening in random packings of entangled granular chains

Random packings of granular chains are presented as a model polymer system to investigate the contribution of entanglements to strain-stiffening in the absence of Brownian motion. The chain packings are sheared in triaxial compression experiments. For short chain lengths, these packings yield when the shear stress exceeds a the scale of the confining pressure, similar to packings of spherical particles. In contrast, packings of chains which are long enough to form loops exhibit strain-stiffening, in which the effective stiffness of the material increases with strain, similar to many polymer materials. The latter packings can sustain stresses orders-of-magnitude greater than the confining pressure, and do not yield until the chain links break. X-ray tomography measurements reveal that the strain-stiffening packings contain system-spanning clusters of entangled chains.Comment: 4 pages, 4 figures. submitted to Physical Review Letter

Initial Results from a Stacked Ring Apparatus for Simulation of a Soil Profile

A stack of 48 rings, lined with a latex membrane, is used to confine a column of soil 12 inches high by 12 inches in diameter (300 mm x 300 mm). Both dry and saturated columns of fine sand are shaken at their base, at a centrifugal acceleration of 35.5 g. Measurements of the settlement of the surface, horizontal displacement and pore pressures show that the columns of soil are behaving essentially (although not exactly) as one-dimensional shear beams

What health inequalities exist in access to, outcomes from and experience of treatment for lung cancer?: A scoping review

Objectives: Lung cancer (LC) continues to be the leading cause of cancer-related deaths and while there have been significant improvements in overall survival, this gain is not equally distributed. To address health inequalities (HIs), it is vital to identify whether and where they exist. This paper reviews existing literature on what HIs impact LC care and where these manifest on the care pathway. Design: A systematic scoping review based on Arksey and O’Malley’s five-stage framework. Data sources: Multiple databases (EMBASE, HMIC, Medline, PsycINFO, PubMed) were used to retrieve articles. Eligibility criteria: Search limits were set to retrieve articles published between January 2012 and April 2022. Papers examining LC along with domains of HI were included. Two authors screened papers and independently assessed full texts. Data extraction and synthesis: HIs were categorised according to: (a) HI domains: Protected Characteristics (PC); Socioeconomic and Deprivation Factors (SDF); Geographical Region (GR); Vulnerable or Socially Excluded Groups (VSG); and (b) where on the LC pathway (access to, outcomes from, experience of care) inequalities manifest. Data were extracted by two authors and collated in a spreadsheet for structured analysis and interpretation. Results: 41 papers were included. The most studied domain was PC (32/41), followed by SDF (19/41), GR (18/41) and VSG (13/41). Most studies investigated differences in access (31/41) or outcomes (27/41), with few (4/41) exploring experience inequalities. Evidence showed race, rural residence and being part of a VSG impacted the access to LC diagnosis, treatment and supportive care. Additionally, rural residence, older age or male sex negatively impacted survival and mortality. The relationship between outcomes and other factors (eg, race, deprivation) showed mixed results. Conclusions: Findings offer an opportunity to reflect on the understanding of HIs in LC care and provide a platform to consider targeted efforts to improve equity of access, outcomes and experience for patients

Mental Health Care in Cuba and the Diaspora A Panel Discussion

This panel takes as its cue the recent publication of Jennifer L. Lambe\u27s book, Madhouse: Psychiatry and Politics in Cuban History, focusing on Mazorra, the island\u27s first psychiatric hospital. The book examines how, from its birth, Cuban psychiatry was politically inflected, drawing partisan contention while sparking debates over race, religion, gender, and sexuality. Psychiatric notions were even invested with revolutionary significance after 1959, as the new government undertook ambitious schemes for social reeducation. Debates about the treatment of mental health issues continued among exiles in South Florida. In particular, the 1980 Mariel boatlift turned into a psychiatric problem both for Cuba and the United States, due to the presence of a large number of mental patients among the migrants. This panel will feature the following speakers: • Dr. Jennifer L. Lambe, Department of History, Brown University • Dr. Eugenio Rothe, Department of Psychiatry, Herbert Wertheim College of Medicine, Florida International University • Dr. Héctor R. Castillo Matos, Nueva América Community Mental Health Center, Miamihttps://digitalcommons.fiu.edu/cri_events/1332/thumbnail.jp

Secondary organic aerosol formation from in-use motor vehicle emissions using a potential aerosol mass reactor.

Secondary organic aerosol (SOA) formation from in-use vehicle emissions was investigated using a potential aerosol mass (PAM) flow reactor deployed in a highway tunnel in Pittsburgh, Pennsylvania. Experiments consisted of passing exhaust-dominated tunnel air through a PAM reactor over integrated hydroxyl radical (OH) exposures ranging from ∼ 0.3 to 9.3 days of equivalent atmospheric oxidation. Experiments were performed during heavy traffic periods when the fleet was at least 80% light-duty gasoline vehicles on a fuel-consumption basis. The peak SOA production occurred after 2-3 days of equivalent atmospheric oxidation. Additional OH exposure decreased the SOA production presumably due to a shift from functionalization to fragmentation dominated reaction mechanisms. Photo-oxidation also produced substantial ammonium nitrate, often exceeding the mass of SOA. Analysis with an SOA model highlight that unspeciated organics (i.e., unresolved complex mixture) are a very important class of precursors and that multigenerational processing of both gases and particles is important at longer time scales. The chemical evolution of the organic aerosol inside the PAM reactor appears to be similar to that observed in the atmosphere. The mass spectrum of the unoxidized primary organic aerosol closely resembles ambient hydrocarbon-like organic aerosol (HOA). After aging the exhaust equivalent to a few hours of atmospheric oxidation, the organic aerosol most closely resembles semivolatile oxygenated organic aerosol (SV-OOA) and then low-volatility organic aerosol (LV-OOA) at higher OH exposures. Scaling the data suggests that mobile sources contribute ∼ 2.9 ± 1.6 Tg SOA yr(-1) in the United States, which is a factor of 6 greater than all mobile source particulate matter emissions reported by the National Emissions Inventory. This highlights the important contribution of SOA formation from vehicle exhaust to ambient particulate matter concentrations in urban areas
