＂Beyond the Dreams of Loveliness＂ --Film, Unionism, and Working Class Community Formation in Detroit, 1933-1939

Ever since Lawrence Goodwyn published The Populist Moment, social historians have been keenly aware of the power culture represents when it comes to resistance. Historically, ＂movement culture＂ has been used to create a collective climate and offered political activists a springboard to discuss with the masses the benefits of joining a social movement. ＂Beyond the Dreams of Loveliness＂ uses the cultural outlet of film and the labor movement in the city of Detroit as analytical tools to examine working class community resistance throughout the 1930s. In the midst of the ＂golden age of film＂ community activists and union organizers--some of whom were well-known radicals and some of whom were mainstream unionists--used the institution of cinema to instill a level of class consciousness in the masses and mobilize the working class community against exploitation of employers, reactionary politicians, and white supremacist organizations. Movie-going had been a very popular form of recreation in Detroit since the 1920s and downtown theatres increasingly became the destination of an eclectic array of workers. Movie theaters themselves were bastions of community activity around the thirties and many were located in the heart of the city＇s working class district. Yet it was the films themselves that offered community activists and unionists a chance to converse with workers regarding the socio-economic matters of the day. Hollywood released a good number of films that dealt with working class issues and provided activists with ample opportunities to ＂instruct＂ the audience and carry on the discussion into the factory or union halls. ＂Beyond the Dreams of Loveliness＂ relies on a combination of oral histories, movie reviews, film clips, and union and/or working class organizational records to illuminate how activists in Detroit＇s working class community used film as an outlet to inspire working class resistance. In sum, film provided an accessible form of entertainment that proved to be effective on two fronts： It promoted increased group cooperation, friendship, and alliances while it also fostered a shared culture, making it easier for activists to organize workers in the coming struggles for unionism.

A universal thermodynamic model of calculating mass action concentrations for structural units or ion couples in aqueous solutions and its applications in binary and ternary aqueous solutions

A universal thermodynamic model of calculating mass action concentrations for structural units or ion couples in ternary and binary strong electrolyte aqueous solution was developed based on the ion and molecule coexistence theory and verified in four kinds of binary aqueous solutions and two kinds of ternary aqueous solutions. The calculated mass action concentrations of structural units or ion couples in four binary aqueous solutions and two ternary solutions at 298.15 K have good agreement with the reported activity data from literatures after shifting the standard state and concentration unit. Therefore, the calculated mass action concentrations of structural units or ion couples from the developed universal thermodynamic model for ternary and binary aqueous solutions can be applied to predict reaction ability of components in ternary and binary strong electrolyte aqueous solutions. It is also proved that the assumptions applied in the developed thermodynamic model are correct and reasonable, i.e., strong electrolyte aqueous solution is composed of cations and anions as simple ions, H2O as simple molecule and other hydrous salt compounds as complex molecules. The calculated mass action concentrations of structural units or ion couples in ternary and binary strong electrolyte aqueous solutions strictly follow the mass action law.

Derivation of Plastic Work Rate Done per Unit Volume for Mean Yield Criterion and Its Application

In Haigh Westergaard stress space linear combination of twin shear stress and Tresca yield functions is called the mean yield （MY） criterion. The mathematical relationship of the criterion and its plastic work rate done per unit volume were derived. A generalized worked example of slab forging was analyzed by the criterion and its corresponding plastic work rate done per unit volume. Then, the precision of the solution was compared with those by Mises and Twin shear stress yield criterions, respectively. It turned out that the calculated results by MY criterion were in good agreement with those by Mises criterion.

Numerical study of n-heptane/benzene separation by thermal diffusion column

In this article,numerical simulations are performed to investigate the performance of the thermal diffusion column for the separation of n-heptane/benzene mixture.The present work tried to optimize column by analyzing significant parameters such as feed flow rate,temperature and cut.In order to obtain the hydrodynamic and temperature and mass distribution inside thermal diffusion column,computational fluid dynamic(CFD) method is applied to solve the Navier-Stocks equations.Numerical simulations are conducted to study the main parameters in both stationary and time-dependent conditions.By using the separation work unit as a function of cut,the optimal cut for maximum SWU occurs within a limited range of 0.47-0.5 for feed rate between 0.5 and 4 g min^-1.Our findings reveal that the optimum feed rate in the range of optimum cut is about 1 g min^-1.In transient study,results show that the best cut for reaching to steady-state condition is θ=0.5.

Delirium Severity and Correlates among Medical Inpatients Admitted through Accident and Emergency Unit of Jos University Teaching Hospital

Background: Delirium is one of the most common medical emergencies and is associated with poor outcomes including: mortality, prolonged length of stay and poor functional outcome. The more severe delirium is the worst the clinical outcomes of medical illness. Despite the obvious, not much has been documented on delirium severity and its associated factors among medical inpatients in low income countries including Nigeria. Objectives: This study was conducted to examine the severity of delirium among medical inpatients admitted through the Accident and Emergency unit of Jos University Teaching Hospital as well as to assess its associated Sociodemographic and Clinical characteristics. Method: This was a cross-sectional study that employed a consecutive sampling technique to select 290 eligible subjects from medical inpatients that presented to Accident and Emergency unit of Jos University Teaching Hospital. On admission, patients were assessed for delirium using Confusion Assessment Method and severity of delirium was evaluated using Delirium Rating Scale-Revised-98. Results: Of the 105 delirious medical inpatients, 48 (45.7%) had severe delirium, 41 (39.1%) developed less severe delirium while 16 (15.2) presented with no severe delirium. Sociodemographic characteristics found to be significantly associated with less to more severe delirium include male gender (P = 0.001), nonprofessionals (P = 0.003), income range of N20,000 - N49,000 (P Conclusion: This study demonstrates that delirium is often associated with higher severity in Accident and Emergency unit admission and there are strongly associated clinical characteristics to watch out for in high risk medical inpatients.

Media Effect of Students’ Ideological and Political Work in Tibetan Agricultural Colleges and Universities
