‘Outside their expertise’: The implications of Field Manual 3-24 for the professional military education of non-commissioned officers

Within the framework of classical theory, the joint US Army-Marine field manual Counterinsurgency (FM 3-24) described an ambitious set of skills required for success against guerrillas. But if counterinsurgency, as FM 3-24 describes it, is ‘the graduate level of warfare’, then these two military services have been for years systematically failing to train their talent in the appropriate fields. In today's small wars, NCOs serve as modern-day Mounties, and consequently require at least a modest undergraduate education in armed good governance.     

Environmental regulation in project‐based industries

We study the environmental regulation of industrial activities that are organized as projects. Applications arise in construction, ship and aircraft building, and film making, among other industries. Relative to manufacturing, environmental regulation is different in project‐based industries, due to the uniqueness and geographical diversity of projects, and a lack of product takeback programs. Because the amount of waste and pollution generated by project companies can be large, regulators need environmental policies to ensure reduction of waste and pollution. We consider a regulator who attempts to maximize social welfare. We model this problem as a bilevel nonlinear program. The upper level regulator specifies waste reduction targets, which the lower level project companies meet using waste stream reduction and remediation of pollution, while attempting to control their project costs. We find that high waste diversion targets lead to outcomes with little pollution, but excessive project costs and only modest waste stream reduction. Projects that have lower task precedence density, or that have pollutants with different environmental impacts, show larger increases in project cost and time resulting from regulation. We describe a subsidy for waste stream reduction that coordinates the system, and we estimate the value of coordination. We also describe a bonus that encourages truthful reporting by project companies, and evaluate the relative cost and effectiveness of the subsidy and the bonus. © 2015 Wiley Periodicals, Inc.

聚钛碳硅烷的新合成法及其研究

从聚硅烷(PS)与钛酸丁酯。(Ti(OBu)_4)出发,不采用任何反应促进剂直接合成了含钛碳化硅纤维的先驱体聚钛碳硅烷(PTC)。在这一反应中,PS 首先裂解成含Si—C 骨架与Si—H 键的低分子聚硅烷(LPS)。然后,由LPS 中的Si—H 键与Ti(OBu)_4的反应以及LPS 的Si—Si 骨架裂解转化为Si—C 骨架的反应制得了PTC.本文对这种新合成法所涉及的反应过程进行了研究,并比较了新旧两法得到的PTC—1与PTC—Ⅱ的结构异同,报告了以新法制得的PTC—Ⅱ为先驱体得到的含钛碳化硅纤维的优良性能。
