摘要： Study Objective: To compare the pain reported by patients during the Essure Micro-Insert sterilization procedure using either intravenous conscious sedation or oral analgesia. Design: Randomized, double-blind, placebo-controlled trial (Canadian Task Force classification 1). Setting: Tertiary care ambulatory women's clinic. Patients: Eighty women of reproductive age women requesting permanent sterilization. Intervention: Hysteroscopic placement of the Essure Micro-Insert permanent birth control system. Measurements and Main Results: Patients undergoing placement of the Essure Micro-Insert system for permanent contraception were randomized to receive either intravenous conscious sedation, oral analgesia, or placebo. During the procedure, pain scores were recorded using a visual analog scale. Patients in the oral analgesia group reported slightly more pain during insertion of the hysteroscope and placement of the second micro-insert;the groups were otherwise equivalent. They were also equivalent when all visual analog scale scores were combined. Conclusion: Oral analgesia is an effective method of pain control during placement of the Essure Micro-Insert permanent birth control system.

摘要： Cognitive control allows humans to overrule and inhibit habitual responses to optimize performance in challenging situations. Contradicting traditional views, recent studies suggest that cognitive control processes can be initiated unconsciously. To further capture the relation between consciousness and cognitive control, we studied the dynamics of inhibitory control processes when triggered consciously versus unconsciously in a modified version of the stop task. Attempts to inhibit an imminent response were often successful after unmasked ( visible) stop signals. Masked ( invisible) stop signals rarely succeeded in instigating overt inhibition but did trigger slowing down of response times. Masked stop signals elicited a sequence of distinct ERP components that were also observed on unmasked stop signals. The N2 component correlated with the efficiency of inhibitory control when elicited by unmasked stop signals and with the magnitude of slowdown when elicited by masked stop signals. Thus, the N2 likely reflects the initiation of inhibitory control, irrespective of conscious awareness. The P3 component was much reduced in amplitude and duration on masked versus unmasked stop trials. These patterns of differences and similarities between conscious and unconscious cognitive control processes are discussed in a framework that differentiates between feedforward and feedback connections in yielding conscious experience.

摘要： This dissertation combines electrochemistry-based battery models and optimal control theory to study power management in energy storage/conversion systems. This topic is motivated by the need to enhance the performance and longevity of battery electric systems. In particular, the rapid progress in battery material science and energy conversion presents a highly relevant opportunity to bridge the knowledge gap between electrochemistry and control. Ultimately, this dissertation elucidates the key physical phenomena in battery-powered systems which enable opportunities to improve battery performance and health through control. We address this topic in three phases. First we provide an overview of battery fundamentals and relevant degradation mechanisms. Then we develop mathematical models for the electrochemical battery phenomena, plug-in hybrid vehicle drivetrain dynamics, and stochastic drive cycle dynamics. A battery-in-the-loop experimental test system is fabricated to identify the electrochemical battery model. Second, we investigate the battery-health conscious power management problem for plug-in hybrid electric vehicles (PHEVs). This effort designs controllers to split engine and battery power to minimize both fuel/electricity consumption costs and battery state-of-health degradation. Mathematically, this problem is formulated as a stochastic dynamic program. The degradation phenomena considered include anode-side solid electrolyte interphase film growth and the "Ah-processed" model. This work is the first to utilize fundamental electrochemical battery models to optimize power management. The final phase proposes a novel battery pack management strategy which investigates the potential health advantages of allowing unequal yet controlled charge levels across batteries connected in parallel. Mathematically, this problem is formulated as a deterministic dynamic program. The optimal solutions reveal that capacity fade can be mitigated through controlled charge une

摘要： 随着经济的发展,人们的生活进一步富裕,各种思潮此起彼伏,享乐主义、自由主义等各种思潮不断地考验着员工。在新形势下,尽管大部分员工都能继承先辈们哪种"责任重于泰山"的优良传统,但仍然有一些人不能有效抵制住各种诱惑,出现事业心责任心不强的现象,贪恋享乐,无心工作,有的甚至出现责任事故,严重影响单位的正常工作和生活,给单位造成严重的损失。本文就此作出具体分析。

摘要： 相对于“意识形态领导权”而言，“意识形态控制力”体现的不是一个阶级的地位而是任务，它将促使一个阶级及其政党牢牢掌握意识形态领导权并贯穿于实践中。意识形态控制力的强化需要在一定的场域中经由一定的手段和途径来完成，而利用意识形态教化实现统治制度的合法化，则具有一切国家机器所不具备的优势。学校思想政治教育因其努力以占支配地位的价值观念与思想方式向受众进行教育，促使受众形成共同持有的价值观、信仰的特性，而成为统治阶级强化意识形态控制力的首选。

摘要： 本文在分析"股东至上"与"共同治理"两种思想基础上,结合人力资本性质及特征提出"双元治理模式,"即内部公司治理结构体现为非人力资本所有者出资后,企业内部董事人力资本所有者群体与经理阶层人力资本所有者群体在合作性竞争博弈的基础上构建的内部治理。在此基础上,提出了内部控制机制的组织框架、控制要素及当前内部控制体系亟待加强的工作:强化内部审计、预算控制、道德规范与行为准则建设。
