Rose-tinted lenses: how American functionalist strategy inhibits our appreciation of complex conflicts

Strategists and military professionals have previously questioned many of the methodological (theoretical underpinnings, the principles, and rules applied by the discipline) decisions associated with American military strategy, but the direction this essay takes is above and beyond the common methodological rivalries in how we pursue strategic desired future states. To get beyond methodological disputes entirely, we must consider thinking about our thinking as an organization on American strategy. Thus, this article hovers between philosophies, organizational theory, as well as our usually unquestioned belief in something called “strategy”. Questioning things about our basic understanding of the world tends to trigger strong organizational defense mechanisms, for good reason. Critical reflection at deep levels puts our worldview, and our role within it at stake. Nonetheless, as strategic disappointment emerges over multiple complex conflict developments, even the most cherished and guarded choices on how the world ought to work are ripe for critical inquiry. This essay examines the limited single strategic paradigm of the US defense industry and how the latest American National Security Strategy and Army Future Operating Concept (Win in a Complex World through 2030) presents a flawed strategic position. This essay presents valid alternative strategies that operate within different paradigmatic constructs.     

‘Look like the innocent flower,but be the serpent under’t’: mimicking behaviour of growth-oriented terrorist organizations

This paper examines the interaction between a growth-oriented terrorist organization and an uninformed government based on a two-period signalling game. Combining the signalling game and organizational growth approaches of previous contributions, this paper shows that, if a terrorist group follows a growth strategy, it has an incentive to appear weaker than it is by mimicking the behaviour of a smaller organization. Depending on its beliefs about the extent of the terrorist threat, it can be optimal for a government to spend more on second-period counter-terrorism measures if it is not attacked in the first period than if it were attacked.     

Operations planning revisited: theoretical and practical implications of methodology

Parts of NATO’s contemporary planning framework called the comprehensive operations planning directive (COPD), and parts of the operation-level planning process should be revised since they suffer from methodological inconsistency. This claim is defended by discussing contradicting methodological properties and heuristics applied when framing and managing a military problem in accordance with the COPD. The methodological inconsistency within the COPD; in other words, simultaneously applying contradictory methodological properties, implies one theoretical and three practical implications. The theoretical implication is summarised in a meta-theoretical framework and explained by discussing five methodological properties: non-linearity, emergence, independently changeable generalisations, invariance and boundaries. The three practical implications of methodology imply that methodology is guiding: the problem-frame, conceptual development and action. To improve military planners’ understanding and management of these four identified implications, NATO is recommended to develop a “handbook of methodology.” The purpose of such a handbook should be to emphasise the utility of methodology when planning military operations.     

Analysis of a production system in a general configuration

We consider a production system comprising multiple stations (or workshops) such as an entry station, a set of work stations, a central station, and an exit station, which are arranged in a general configuration. A worker (or a vehicle tool) is assigned to each station, who sends a part from the station to the destination station according to the required process path of the part. Any part is allowed to visit a work station more than once if its process path requires. We propose a new control strategy with the push policy for instructing each worker to send a part and the kanban mechanism for controlling the work‐in‐process (WIP) in each work station. As all work stations have limited local buffers, the central station is used for storing blocked parts temporarily. Such a production system is modeled as an open queueing network in a general configuration with a Markovian part sending policy and a machine no blocking mechanism. The queueing network is analytically characterized. Some important performance measures are compared with other control strategies. A semi‐open decomposition approach is applied to the queueing network for computing the blocking probabilities when parts arrive at the work stations. An algorithm is developed based on the semi‐open decomposition approach. Numerical experiments show the quality of the solutions obtained by the algorithm as well as a property of a performance measure. © 2001 John Wiley & Sons, Inc.

加强党性党风建设 提高党员干部的整体水平

党性党风建设历来是我党高度重视的一个问题。高校领导干部亦不例外。目前 ,高校基层党员干部普遍存在政治理论水平不高 ,道德修养变形 ,党的意识淡薄等现象。要想提高高校基层党员干部党性党风建设的整体水平 ,就必须加强对其进行政治理论教育和道德教育 ,同时加强制度建设。唯有此 ,才能提高基层管理者的管理水平和整体办学层次

Forces of heresy versus forces of conservation: making sense of Hezb-e Islami-ye Afghanistan’s and the Taleban’s positions in the Afghan insurgency

Ethnicity and ideology are frequently used to determine whether an armed group is hostile or friendly vis-à-vis the state. By contrast, I argue that the social structure of insurgent movements holds more explanatory power for their respective positions than ethnicity or ideology. To illustrate this, I apply Pierre Bourdieu’s concept of a contest between forces of ‘conservation’ and forces of ‘heresy’ to the current Afghanistan war. I demonstrate that the social structure of the Taleban renders them prone to ‘heresy’, while the formerly second biggest insurgent group, Gulbuddin Hekmatyar’s party, has rather been an impeded force of ‘conservation.’
