An interactive paired comparison method for bicriterion integer programming

This article proposes an interactive paired comparison region elimination method for bicriterion integer mathematical programming problems. The new method isolates the best compromise solution by successively evaluating a pair of associated supported non-dominated solutions. The efficiency of the method is tested by solving randomly generated problems based on varying shapes of efficient frontiers. When compared with the existing branch-and-bound method, the method was effective in reducing the burden on the decision maker. © 1994 John Wiley & Sons, Inc.     

One more push: Forcing the Dardanelles in March 1915

The historiography of the Gallipoli campaign suggests that the Turks were critically short of ammunition for the Dardanelles coastal defences in March 1915. This theme, established by Winston Churchill, became the basis for a widespread belief that the Royal Navy, after its failure to carry the Dardanelles on 18 March 1915, simply needed one more determined naval push to breakthrough the narrows. The presumed consequence was that the Ottoman Empire, with Constantinople under the guns of the Royal Navy, would have withdrawn from the war. Using modern Turkish sources, the author examines the available quantities, placement, and expenditure of ammunition, and challenges the premise that the Turks were desperately short of heavy shells. The author concludes that the Turks had sufficient remaining ammunition to fiercely contest control of the straits.     

Bayonets on Musa Dagh: Ottoman Counterinsurgency Operations – 1915

This article examines the Ottoman military's escalatory response to violence and frames the Armenian insurrection of 1915 in the historical context of contemporary early twentieth-century counterinsurgency campaigns. A case study is presented, from a military historian's perspective, of counterinsurgency operations conducted by the Ottoman Army's 41st Infantry Division against Armenian insurgents on Musa Da? (Musa Dagh) in an operational area south of Iskenderun (Alexandretta). In this particular operational area, it appears that the modern label which most closely approximates what happened there is ethnic cleansing. Finally, the article concludes with an objective assessment of the effectiveness of the Ottoman Army's counterinsurgency operations.     

Chinese Theater and Strategic Missile Force Modernization and its Implications for the United States

The People's Republic of China (PRC), no longer content with its longstanding ‘minimalist’ nuclear posture and strategy, is enhancing the striking power and survivability of its theater and strategic missile forces and rethinking its nuclear doctrine in ways that may pose serious challenges for the United States. Although the modernization of Chinese nuclear and missile forces may ultimately result in greater strategic deterrence stability, this change will not come about immediately or automatically. Indeed, it is entirely possible that China's growing missile capabilities could decrease crisis stability under certain circumstances, especially in the event of a US–China conflict over Taiwan.     

The sensitivity of first term navy reenlistment to changes in unemployment and relative wages

Multiple regression analysis was used to analyze newly developed twenty year time series of first term reenlistment rates for nine major Navy occupational categories. Results indicate that there are significant differences among the occupational categories in the determinants of their reenlistment behavior. More importantly, it is apparent that reenlistment rates are highly sensitive to current unemployment and especially unemployment about the time of enlistment. By comparison, relative wages (measures of military versus private sector rates of compensation) are relatively insignificant and appear powerless to control reenlistment in the context of normal fluctuations in economic activity.     

A graphical aid for sensitivity analysis of estimated regression coefficients

A problem often arising in applied linear regression modeling is determining the appropriate weight to attach to each observation. In the extreme, the problem extends to the deletion of observations from a data base. Since the choice of weights, fitting criteria, and estimation procedure depend on the specific objectives of the modeling, universally applicable guidelines are virtually nonexistent. However, the sensitivity of analytic conclusions to weights assigned to “suspect” observations can be conveniently assessed using a graphical display. This report develops such a display based on a modeling of outliers which leads naturally to estimators based on a weighted least-squares criterion, and a data-analytic method for determining how much downweighting to impose on a specific subset of observations. This technique is illustrated with several examples, including one relating air pollution to human mortality.     

Rising Tide,Dispersing Waves: Opportunities and Challenges for Chinese Seapower Development

Abstract

This article surveys China’s current naval forces and considers key dynamics and possible Chinese naval futures to 2020, the projected end of Beijing’s ‘strategic window of opportunity’, the idea that a peaceful external environment for economic development, globalization, and integration of China into the global economy allows China to benefit from diversion of US attention to countering terrorism. It considers broad possibilities through 2030, the general limit of public US government projections, and by which time multiple factors will likely slow China’s growth and compete for leadership focus and resources.
