Deciding on Military Intervention—What Is The Role of Senior Military Leaders?

Deliberations on the possible use of force have usually failed to provide U.S. leaders with the information and advice necessary to make informed decisions. How can this be improved

The Intervention Debate: Towards a Posture of Principled Judgment

The author argues that American policymakers must take an approach based on principled judgment when deciding on the use of force. The 1990s showed the extremes of deciding when and how to use force, one of the central elements of strategy. Throughout American history, debate has raged over whether force is appropriate only in defense of the homeland and vital national interests or whether it should also be used to promote more expansive objectives like regional security and stopping humanitarian disasters in regions with few tangible U.S. interests. He concludes with a discussion of Army roles and requirements for future contingencies.https://press.armywarcollege.edu/monographs/1828/thumbnail.jp

Investigation of recast and crack formation in laser trepanning drilling of CMSX-4 angled holes

This paper presents an experimental investigation on the influences of laser trepanning drilling process parameters on the recast layer thickness and surface crack formation in CMSX-4 nickel-based superalloy angled holes. The effects of peak power, pulse frequency and the trepanning speed as input parameters were investigated in details by varying the laser drilling conditions using Taguchi orthogonal array-based design of experiment approach. Analysis of variance identifies the significant parameters affecting the output responses. It is found that the output responses are affected mainly by the peak power and trepanning speed. The experimental results reveal that the recast layer thickness increases with the increase of peak power and trepanning speed whereas the crack number density decreases with the increase of peak power only. Pulse frequency has no significant effect on both output responses within the range of values investigated. The knowledge gained in this parametric study could be used to improve the metallurgical characteristics of laser-drilled nickel-based acute angled holes

Bringing the margin to the focus: 10 challenges for riparian vegetation science and management

Riparian zones are the paragon of transitional ecosystems, providing critical habitat and ecosystem services that are especially threatened by global change. Following consultation with experts, 10 key challenges were identified to be addressed for riparian vegetation science and management improvement: (1) Create a distinct scientific community by establishing stronger bridges between disciplines; (2) Make riparian vegetation more visible and appreciated in society and policies; (3) Improve knowledge regarding biodiversity—ecosystem functioning links; (4) Manage spatial scale and context-based issues; (5) Improve knowledge on social dimensions of riparian vegetation; (6) Anticipate responses to emergent issues and future trajectories; (7) Enhance tools to quantify and prioritize ecosystem services; (8) Improve numerical modeling and simulation tools; (9) Calibrate methods and increase data availability for better indicators and monitoring practices and transferability; and (10) Undertake scientific validation of best management practices. These challenges are discussed and critiqued here, to guide future research into riparian vegetation

Reconciliation in the Asia-Pacific

Asia’s brutal colonial and wartime his- tory has left wounds that continue to shape the region’s politics and interna- tional relations. Traditional approaches to international relations say little about how to overcome lingering ani- mosity and to replace it with trust and harmonious relations. Time alone is never a solution. Nor, as Japan has dis- covered repeatedly, are apologies enough. Even need, as that between de- veloping China and economically and technologically advanced Japan, is in- sufficient. The contributors to this vol- ume demonstrate that the path to reconciliation is different for each country, requiring unique blends of a wide range of political and social ingre- dients, many of which are in short supply
