International Conflict and Collective Security: The Principle of Concern in International Organization

The control of man’s violence against man presents to modern society its greatest problem. A capacity to deal with the most devastating type of conflict—international war—is crucial to human welfare and even to the survival of civilization. Nations have become interdependent in technology and economy, but world political organization is based on a system of sovereign states now divided into hostile camps armed with absolute weapons. This book is a study of the development of collective security, or international cooperative action for the maintenance of peace. The approach is based upon the “principle of concern,” a recognition of the fact that organization to preserve peace is essential for every political community. As a case study Willard N. Hogan has analyzed the principle of collective security as it has worked in practice in international organizations over the past thirty-five years. He holds that collective security is not unworkable as a method for stopping aggression and maintaining peace. Willard Hogan is professor of political science at State University Teachers College, New Paltz, New York, and director of the Information Center for the United Nations at the same college.https://uknowledge.uky.edu/upk_political_science_international_relations/1009/thumbnail.jp

Measurement of charged particle spectra in minimum-bias events from proton-proton collisions at root s =13 TeV

Pseudorapidity, transverse momentum, and multiplicity distributions are measured in the pseudorapidity range vertical bar eta vertical bar 0.5 GeV in proton-proton collisions at a center-of-mass energy of root s = 13 TeV. Measurements are presented in three different event categories. The most inclusive of the categories corresponds to an inelastic pp data set, while the other two categories are exclusive subsets of the inelastic sample that are either enhanced or depleted in single diffractive dissociation events. The measurements are compared to predictions from Monte Carlo event generators used to describe high-energy hadronic interactions in collider and cosmic-ray physics.Peer reviewe
