Exporting professionalism: US efforts to reform the armed forces in the Dominican Republic and Nicaragua, 1916–1933

Why did the United States, a country notorious for supporting coups and military dictatorships in Latin America during the Cold War, seek to depoliticize security forces in the Caribbean basin during the early twentieth century? Drawing from primary sources, I argue that this emphasis on military non-partisanship abroad stemmed from Progressive Era reforms popular at home. These reforms, which stressed bureaucratic efficiency via nonpartisan expertise, had become institutionalized within the US military and State Department and then channelled into the imperial administration of Nicaragua and the Dominican Republic. The State Department and Marine Corps attempted to replace local partisan armies with the kind of professional, nonpartisan armed forces that the US's own military had come to exemplify. That these civil-military reform efforts ultimately backfired should serve as a reminder of the difficulties inherent in using military interventions to transform coercive apparatuses and their societies.     

Friend or foe? The Cyprus Police Force and the EOKA insurgency

This article examines the ambiguous role played by the Cyprus Police Force during the Greek Cypriot insurgency against Britain between 1955 and 1959. A multiethnic force policing a multiethnic society, the CPF struggled to fulfill its duties. Greek Cypriot officers became ineffective as sympathy for, or fear of insurgents undermined their ability to function. Some collaborated, others resigned. Those who stayed became targets of their own people. Turkish Cypriot officers, recruited in greater numbers to compensate for a reduction in Greek Cypriot officers, worked to enforce the law, but exacerbated intercommunal relations in doing so. In spite of the peculiar conditions present in Cyprus, the case has valuable implications for contemporary policymakers on the vulnerabilities inherent in the use of local police forces to restore law and order in ethnically divided societies.     

India and Israel: emerging partnership

The absence of formal diplomatic relations between India and Israel from India's hesitant recognition of Israel in 1950 and the establishment of full relations in January 1992, was the result of a complex interplay between two sets of tensions. The first involved the Arab–Israeli dispute, and India's sympathies with a post-colonial Arab world and with the Non-Aligned Movement; the second involved accommodating Muslim opinion within India. Normalization has proceeded more strongly as the growth of Hindu nationalism has weakened Muslim leverage on Indian foreign policy.     

Comment: Why “an identified systemic model of the democracy‐peace nexus” does not persuade*

In their article in this journal, James, Solberg and Wolfson (1999) challenge our findings that two states are more likely to have peaceful relations if they are both democratic. They claim to develop a simultaneous system of two equations showing that peace and democracy foster each other, and that the effect of peace in encouraging democracy is stronger than that of democracy on peace. Their analysis, however, is flawed. Their research design employs measures of dispute and joint democracy that are inferior to those now common in the literature, and their equation for predicting peace is not properly specified. These problems distort their results. Even so, their results provide evidence of the pacific benefits of democracy. Analyses we conduct with a more completely specified model reveal stronger support for the democratic “ peace. Furthermore, a test of the effect of interstate conflict on democracy should be done at the national (or monadic) level of analysis; but James et al. perform a dyadic analysis. In a monadic test using vector autoregression, we find that disputes make no contribution to explaining the character of regimes. Even with their dyadic method, their finding that peace promotes democracy is not robust Including a crucial control variable, the ratio of militarily relevant national capabilities, that James et al. omitted, dramatically alters their findings.     

Performance evaluation of a production/inventory system with periodic review and endogenous lead times

This paper considers a discrete time, single item production/inventory system with random period demands. Inventory levels are reviewed periodically and managed using a base‐stock policy. Replenishment orders are placed with the production system which is capacitated in the sense that there is a single server that sequentially processes the items one at a time with stochastic unit processing times. In this setting the variability in demand determines the arrival pattern of production orders at the queue, influencing supply lead times. In addition, the inventory behavior is impacted by the correlation between demand and lead times: a large demand size corresponds to a long lead time, depleting the inventory longer. The contribution of this paper is threefold. First, we present an exact procedure based on matrix‐analytic techniques for computing the replenishment lead time distribution given an arbitrary discrete demand distribution. Second, we numerically characterize the distribution of inventory levels, and various other performance measures such as fill rate, base‐stock levels and optimal safety stocks, taking the correlation between demand and lead times into account. Third, we develop an algorithm to fit the first two moments of the demand and service time distribution to a discrete phase‐type distribution with a minimal number of phases. This provides a practical tool to analyze the effect of demand variability, as measured by its coefficient of variation, on system performance. We also show that our model is more appropriate than some existing models of capacitated systems in discrete time. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

Waiting time analysis of the M/G/1 queue with finite retrial group

We consider an M/G/1 retrial queue with finite capacity of the retrial group. First, we obtain equations governing the dynamic of the waiting time. Then, we focus on the numerical inversion of the density function and the computation of moments. These results are used to approximate the waiting time of the M/G/1 queue with infinite retrial group for which direct analysis seems intractable. © 2007 Wiley Periodicals, Inc.

Interval scheduling: A survey

In interval scheduling, not only the processing times of the jobs but also their starting times are given. This article surveys the area of interval scheduling and presents proofs of results that have been known within the community for some time. We first review the complexity and approximability of different variants of interval scheduling problems. Next, we motivate the relevance of interval scheduling problems by providing an overview of applications that have appeared in literature. Finally, we focus on algorithmic results for two important variants of interval scheduling problems. In one variant we deal with nonidentical machines: instead of each machine being continuously available, there is a given interval for each machine in which it is available. In another variant, the machines are continuously available but they are ordered, and each job has a given “maximal” machine on which it can be processed. We investigate the complexity of these problems and describe algorithms for their solution. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007
