Are low-income families victims of high prices in small neighborhood stores? This article goes beyond asking what prices small stores charge and examines the purchasing patterns of low-income families. What kind of stores do they patronize? Why? Do they use the convenience stores in the low-income areas? Do many buy food on credit? How well do they perceive price differences among stores? These are some of the questions answered through a survey in a Philadelphia redevelopment area. [ABSTRACT FROM AUTHOR]

The article reports on the housebuilding industry as a coordination of products and materials and seeks to evaluate the production process as a whole with a goal of increased efficiency. The millwork industry and warm air furnaces markets are cited as specific examples. The process of extracting wood material, processing the wood at mills and marketing the wood to builders is expressed. For furnaces, the casting process, foundries' contributions, shipping, processing, and assembling furnaces before they are sold to builders is another coordinated effort. Housebuilding is evaluated with respect to the entire process.

Deals with the unions of physicians in the United States. Frustration of doctors over the managed care system; Difference between the American Medical Association and a traditional union; Opportunity given by unions for doctors to recapture their profession.

Purpose: Limited resection has been increasingly used in older patients with stage IA lung cancer. However, the equivalency of limited resection versus lobectomy according to histology is unknown., Methods: We identified patients older than 65 years with stage IA invasive adenocarcinoma or squamous cell carcinoma ≤ 2 cm who were treated with limited resection (wedge or segmentectomy) or lobectomy in the Surveillance, Epidemiology, and End Results-Medicare database. We estimated propensity scores that predicted the use of limited resection and compared survival of patients treated with limited resection versus lobectomy. Treatments were considered equivalent if the upper 95th percentile of the hazard ratio (HR) for limited resection was ≤ 1.25., Results: Overall, 27% of 2,008 patients with adenocarcinoma and 32% of 1,139 patients with squamous cell carcinoma underwent limited resection. Survival analyses, adjusted for propensity score by using inverse probability weighting, showed that limited resection was not equivalent to lobectomy in patients with adenocarcinoma (HR, 1.21; upper 95% CI,1.34) or squamous cell carcinoma (HR, 1.21; upper 95% CI, 1.39). Although patients with adenocarcinomas treated with segmentectomy had equivalent survival rates to those treated with lobectomy (HR, 0.97; upper 95% CI, 1.07), outcomes of those treated with wedge resection (HR, 1.29; upper 95% CI, 1.42) did not. Among patients with squamous cell carcinoma, neither wedge resection (HR, 1.34; upper 95% CI, 1.53) nor segmentectomy (HR, 1.19; upper 95% CI, 1.36) were equivalent to lobectomy., Conclusion: We found generally that limited resection is not equivalent to lobectomy in older patients with invasive non-small-cell lung cancer ≤ 2 cm in size, although segmentectomy may be equivalent in patients with adenocarcinoma., (© 2015 by American Society of Clinical Oncology.)
