发展靠改革 改革求创新——访上海烟草工业印刷厂俞志康厂长

从中央对“十一五”规划的部署来看,我国的发展又进入了一个新的历史阶段。规划强调改变经济的增长方式,提高资源利用率,调整经济增长与资源环境制约之间的矛盾,继续实施产业结构的调整,对企业兼并改组的力度还将加强,钢铁、石油、石化、烟草等均在其列。占国家税收重头的烟草业,自2003年就迎来一次“地震”式的重组。2006年1月11日,国家烟草专卖局又宣布,正式启动“打造十大烟草航母集团”的计划,将对现有44家烟草企业进行整合,组建成以品牌为支撑的十大烟草航母集团。这对长期以来依靠烟草企业而生存发展的烟草印刷企业来说,如何面对这种改组,并规划好自身的发展,采取哪些应对策略与措施,也就成了那些不甘寂寞,且仍想稳操胜券的烟印企业领导们关注的焦点。其实,在钢铁、石油、石化以及其他大型企业集团长期庇护下的印刷企业又何止少数?这些企业的领导人也该从“手捧铁饭碗,稳坐太师椅”的状态中有所觉醒、有所思考吧?所以这次我们采访上海烟草印刷厂领导的目的,说白了,绝不仅仅是为了报道上海烟印自强不息的光辉篇章,而是通过这一报道,给面临行业整合改组的印企领导们奉上一道醒酒菜。毕竟在葡萄美酒前自我陶醉的好景不会太久了,还是尽快作好优胜劣汰的竞争准备吧。     

Robust adaptive control of robotic manipulators without the regressor matrix

A new adaptive controller is presented here for rigid-body robotic manipulators. It is stable and robust with respect to a class of external disturbances. The robustness of the adaptive controller is established without the ‘slow-varying’ assumption and the computationally demanding regressor matrix. The control law consists of a non-adaptive PD control part and an adaptive control part. It uses two adaptive matrices to compensate two uniformly bounded coefficient matrices derived from the original dynamics. A α σ|q?|-modified adaptive law is designed to adjust the adaptive matrices. A Lyapunov-type stability analysis indicates that the closed-loop system is uniformly ultimately bounded. The tracking error and compensation error will eventually converge into a closed region, which can be made arbitrarily small by adjusting the controller parameters. Simulation results are included to demonstrate the performance of the proposed controller.

Relationship of provider characteristics to outcomes, process, and costs of care for community-acquired pneumonia

OBJECTIVES: The authors describe the relation of provider characteristics to processes, costs, and outcomes of medical care for elderly patients hospitalized for community-acquired pneumonia. METHODS: Using Medicare claims data, Medicare beneficiaries discharged from Pennsylvania hospitals during 1990 with community-acquired pneumonia were identified. Claims data were used to ascertain mortality, readmissions, use of procedures and physician consultations, and the costs of care. The relationship of these measures to provider characteristics was analyzed using regression techniques to adjust for patient characteristics, including comorbidity and microbial etiology. RESULTS: Among 22,294 pneumonia episodes studied, 30-day mortality was 17.0%. After adjusting for patient characteristics, 30-day mortality and readmission rates were unrelated to hospital teaching status or urban location or to physician specialty. Use of procedures and physician consultations was more common and costs were 11% higher among patients discharged from teaching hospitals compared with nonteaching hospitals. Similarly, costs were 15% higher at urban hospitals compared with rural hospitals. General internists and medical subspecialists used more procedures and had higher costs than family practitioners. CONCLUSIONS: Processes and costs of care for community-acquired pneumonia varied by provider characteristics, but neither mortality nor readmission rates did. These differences cannot be explained by clinical variables in the database. Further studies should determine whether less costly patterns of care for pneumonia, and perhaps other conditions, could replace more costly ones without compromising patient outcomes.
