Naval Research Program 2019 Annual Report

NPS NRP Annual ReportThe Naval Postgraduate School (NPS) Naval Research Program (NRP) is funded by the Chief of Naval Operations and supports research projects for the Navy and Marine Corps. The NPS NRP serves as a launch-point for new initiatives which posture naval forces to meet current and future operational warfighter challenges. NRP research projects are led by individual research teams that conduct research and through which NPS expertise is developed and maintained. The primary mechanism for obtaining NPS NRP support is through participation at NPS Naval Research Working Group (NRWG) meetings that bring together fleet topic sponsors, NPS faculty members, and students to discuss potential research topics and initiatives.Chief of Naval Operations (CNO)This research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.

A Survey of the European Security Market

This document synthesizes the results of the research made on the European security market. It deals with questions of interest regarding the provision of security goods and services for protecting society from terrorism and organised crime. It explores issues such as market revenues, demand and supply, industrial capabilities, technology, research and development, innovation, business strategies, competition as well as market structure, agents' conduct and economic performance. The research has been based upon desk analysis of open source information related to the security market. Economic theory and critical analysis has been applied to understand the gathered information, derive knowledge, point out key issues and assess trends and drivers that will likely shape the sector's future. The study is the outcome of the working package number 5 included in the research project A new Agenda for European Security Economics (EUSECON). This project with code number 218195 has been financed by the European Commission within the 7th European Research Framework Programme. The task has been performed by the company ISDEFE according to the scope and work plan described in the EUSECON proposal. The author wishes to express his appreciation to all the individuals that have provided input and valuable comments to this study, including anonymous referees. Any flaws or omissions contained in this document are solely the responsibility of the author.

Synthesis, Interdiction, and Protection of Layered Networks

This research developed the foundation, theory, and framework for a set of analysis techniques to assist decision makers in analyzing questions regarding the synthesis, interdiction, and protection of infrastructure networks. This includes extension of traditional network interdiction to directly model nodal interdiction; new techniques to identify potential targets in social networks based on extensions of shortest path network interdiction; extension of traditional network interdiction to include layered network formulations; and develops models/techniques to design robust layered networks while considering trade-offs with cost. These approaches identify the maximum protection/disruption possible across layered networks with limited resources, find the most robust layered network design possible given the budget limitations while ensuring that the demands are met, include traditional social network analysis, and incorporate new techniques to model the interdiction of nodes and edges throughout the formulations. In addition, the importance and effects of multiple optimal solutions for these (and similar) models is investigated. All the models developed are demonstrated on notional examples and were tested on a range of sample problem sets

Beyond Nelson: A Post-heroic Study of Leader-Follower Interaction in the Royal Navy

Leadership studies have traditionally considered leader characteristics to account for leadership outcomes such as leader emergence or team performance. This heroic narrative has always had its opponents but recently a post-heroic approach is becoming more prominent. Post-heroic approaches contest the assertion that leadership outcomes are mainly the product of leader traits. My research begins with a particular leader trait, the ability to interact, and bridges the two approaches by investigating the process from leader competence to leadership outcomes. The research uses a sequential exploratory design incorporating mixed methods. Three projects were conducted in Royal Navy (RN) warships. A qualitative project developed a leader-follower interaction model. The model suggests that leadership is granted by followers after a long-term series of mundane encounters. These encounters allow followers to build a group consensus of leader prestige. Prestige inuences follower behaviour such as engagement, disengagement and a covert form of resistance called levelling. A second project mapped the advice and participation networks on RN vessels and determined the prestige of team and sub-team leaders. Regression techniques allowed me to verify empirically the signicant relationship between prestige scores and team performance for ships conducting Sea Training. A nal project conducted on a warship in the South Atlantic verified a similar relationship between advice network prestige and intra-team communication. Finally I used the findings of the two empirical projects, based on sub-team or dyadic relationships, to model the effects of prestige at the group level, using computer simulation. I discovered that prestige that is dispersed throughout a group generates more effective teams, in terms of communication, than other conditions. This challenges the traditional top-down view of leadership communication. The resulting leader-follower interaction model describes a series of mundane and contested encounters through which prestige is given to dispersed leaders within a group. The theoretical impact of my research is to develop trait-process approaches to leadership and to describe leader-follower interaction as a post-heroic process. In doing so, I synthesise engagement theory with antropological approaches, including resistance to leadership. Practically, my projects validate the RN's compentency method of selecting leaders but points out that prestigious leaders alone cannot maximise team performance

Canadian Navy and domestic maritime enforcement

The objective of this research is to evaluate the employment of the Canadian Navy in a maritime enforcement role within the Canadian maritime zones. This investigation is comprised of two main parts: an analysis of the Canadian political and regulatory structures, as well as an analysis of naval enforcement operations. The marine geography of Atlantic Canada is described through six key ocean-use sectors, followed by an analysis of important oceans policy initiatives, and the federal government's ad hoc approach to security and defence policy formulation. The mandates, jurisdictions, and general capabilities of Canadian federal departments with either direct or indirect links to marine security and maritime enforcement are discussed, as well as the legal framework for the use of Canadian military forces for domestic operations. The second part of the thesis analyses the capabilities that the Navy brings to maritime security and enforcement operations. These include the contribution to maritime domain awareness, government "presence" derived through aerial surveillance, search and rescue operations, and naval support to fisheries enforcement. An analysis of patrol patterns is offered, as well as spatial analyses of at-sea inspection data. Two exploratory studies that address the perceived deterrent value of naval support to fisheries enforcement, and public opinion as it pertains to naval support to constabulary operations are presented, as well as the effect that fisheries support missions have on the combat readiness of warships. The thesis suggests that the Canadian Navy could take on a greater role in domestic enforcement, and a proposal is made for enhanced legal powers. The thesis ends by summarizing the Navy's important role championing and enabling improvement in the government's Marine Security Response System, as well as a whole-of- government approach to maritime surveillance planning.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
