Security risk analysis is the term used to describe the analysis of critical facilities in which the initiating events of possible accident sequences are human actions intentionally carried out with the objective of causing harm and/or damage. Several methodologies are available for security risk assessment, which are applicable to different domains. In general, they are characterised by the following phases: 1) Identification of possible adversaries; 2) Identification of possible targets (assets); 3) Vulnerability analysis of the infrastructure; 4) Security Risk Analysis; and 5) Improvement of the protection measures. Generally an installation contains multiple assets that need to be protected. A sequence of attack to a given asset describes the paths the adversary has to follow to reach the target. Protection systems are in place to detect the presence of non-authorised people and to trigger alarms to security forces. Parts of these systems protect different assets. The vulnerability analysis of the installation aims at identifying the weakest point of the protection system that could be exploited by the attackers. This paper describes a methodological approach to implement in particular steps 3-5 of the aforementioned process. Attack scenarios to each asset of interest are identified and modelled by means of event trees and attack trees...

Increased situational awareness in the battlefield is one of the main objectives in today?s operations and applies to all levels of commands. Several attempts have been made to use tracking devices for detecting and continuously updating the positional data of friendly assets on a map. Current applications like Falcon View fulfill their objective in presenting the location of targets of interest on a digital mapping environment. Falcon View is a geographic information system (GIS) used extensively by DoD for mission planning purposes. When the requirement is to track airborne assets such as aircraft or unmanned aerial vehicles (UAVs), none of the current applications can present the results in three-dimensions. Instead they project the received tracks on the ground in 2-dimensions creating a false or impaired perspective of the true tactical situation. This thesis develops and tests a software application in a plug-in form integrated into the open-source NASA World Wind mapping engine. The application is designed to determine the tracks of both airborne and ground-moving assets in three dimensions. It also tests the concept in a real-world environment and verify the impact it has on situational awareness at various command levels.

Approved for public release; distribution in unlimited.; This thesis is an attempt to define how some of the commercial space assets already in use or under development could be useful to the Argentine Navy as tools for better accomplishment of their basic missions. Research efforts involved investigating part of what is available on the international market and some space related international laws and policies that may represent limits for military use of civilian assets. Basically divided in two main areas, communications and remote sensing, this thesis covers the basics of GEO and LEO communication satellites and provides an overview of what could be expected from commercial remote sensing systems. Through examples, the feasibility of using civilian space assets in the military is demonstrated. Finally, an objective analysis is made to define the best approach to improve Argentine Navy space capabilities

This thesis sought to research the causes of the accumulation of assets due to unmatched receipts within the Aviation Repairable Tracking system determine the significance of these assets to the system as a whole and make recommendations for recoupling the value of the assets and for applying them to the correct appropriation account. The study was conducted from a management control perspective In addition to the economic impact, workload impact on all levels, from fleet to staff, were considered before any recommendations were made. The major recommendation is that a system change be made so that all asset turn ins should coded as credits and thus they will generate replenishment funds to the specific appropriations and budgets.

Military Operations Research, 5(2), 2000, pp. 77-91.; Finding the correct balance between investment in weapons and information assets has proven to be a substantial challenge. Information alone cannot defeat the enemy on the battlefield, but modern long-range weaponry is useless without the information necessary to deploy it. We present a new optimization methodology that combines attack assets and bomb-damage assessment sensors in a single allocation model. The resulting model allows analysis of the tradeoffs between information (sensor) and transformation (attack) assets. We discuss the computational difficulties of the problem and cover the motivating ideas behind the methodology. Then, we outline the mathematical techniques used, and present results for a notational data set.

This article studies the valuation of boundary-linked assets and their derivatives in continuous-time markets. Valuing boundary-linked assets requires the solution of a stochastic differential equation with boundary conditions, which, often, is not Markovian. We propose a wavelet-collocation algorithm for solving a Milstein approximation to the stochastic boundary problem. Its convergence properties are studied. Furthermore, we value boundary-linked derivatives using Malliavin calculus and Monte Carlo methods. We apply these ideas to value European call options of boundary-linked assets

A dissolução do vínculo conjugal por divórcio, declaração de nulidade ou anulação do casamento faz cessar as relações patrimoniais entre os cônjuges e conduz à partilha do património conjugal. Procede-se, ainda, à partilha no caso de vir a ser decretada a separação judicial de pessoas e bens, a simples separação judicial de bens ou nos demais casos previstos na lei de separação de bens na vigência da sociedade conjugal. Acontece, porem, que não é com a sentença que decreta o divórcio ou com a decisão que determina a separação de bens que terminam, de facto, as relações patrimoniais entre os cônjuges.Esta situação, embora por natureza transitória, destinada que está à liquidação, pode apesar disso perdurar, suscitando os problemas próprios das relações de contitularidade. O presente papel pretende inventariar os problemas que, a este própósito, se levantam e propor, ainda que de forma necessariamente ligeira, solução, à luz da lei vigente e de jure constituendo, quando o ordenamento jurídico – como, ver-se-á, acontece algumas vezes – não a oferece ou não o faz de forma clara. Dissolution of the marriage by divorce, annulment of marriage, simple separation of assets...

This paper compares assets-based portfolio management fees to profits-based fees. Whilst both forms of compensation can provide appropriate risk incentives, fund managers' limited liability induces more excess risk-taking under a profits-based fee contract. On the other hand, an assets-based fee is more costly to investors. In Spain, where the law explicitly permits both forms of retribution, assets-based fees are observed far more frequently. Under this type of compensation, the paper provides some insights into how management fees should be determined in order to solve the principal's trade-off between providing better risk incentives and incurring a lower cost of compensation.

Joint Applied Project; The objective of this Joint Applied Project was to examine the technical, financial, and implementation aspects for DoD transitioning POR systems to IPv6. The research outlines the initial intended useful life and limitations of IPv4 and IPv6. The financial aspects of transitioning to IPv6 are examined from a programs perspective, relative to the Program Objective Memorandum (POM). Implementation of transition strategies and mechanisms are identified and courses of action for implementing the mandatory IPv6 requirement are recommended. The principal finding of this research is that DoD Global Information Grid (GIG) assets must function in a dual IPv4/IPv6 capacity when transitioning to IPv6 in order to maintain the relevance of currently fielded programs. Furthermore, legacy GIG assets should be transitioned using Technology Refresh or Software Block upgrade programs while paying careful attention to the effects the transition has on tactical network operations.; US Army (USA) author.

Economic theory predicts that money is an important determinant of macroeconomic variables but fails to clearly define which assets should be considered money. Benjamin Friedman (1984) rejected the hypothesis that the major monetary aggregates move closely together over substantial periods of time. Thus, the central bank cannot simply pick one monetary aggregate, target it appropriately, and ignore mixed signals. Separability of preferences provides an explicit criteria for determining which assets should be considered as money. An aggregate based on separability will satisfy two properties. First, the total amount of the aggregate desired can be determined independent of the size of the aggregate's individual components. Second, changes in the relative size of the aggregate's components which leave the aggregate's total unchanged will not affect the choice of other assets and commodities. These properties indicate that an aggregate based on separability will have a more stable relationship with GNP than any other aggregate. Barnett (1980) first argued this proposition. Separability imposes structure on the Hessian matrix. Imagine a partition of the n goods of the choice set into m groups. If preferences are separable in this partition...

The authors assess empirically the impact of contractual savings institutions portfolios (pension funds and life insurance companies) on securities markets, for example, depth and liquidity in the domestic stock market, and depth in the domestic bond market. They discuss how the institutionalization of savings can modify financial markets through the lengthening of securities' maturities. The results are the following: 1) An increase in assets of contractual savings institutions relative to domestic financial assets has a positive impact on the depth of stock and bond markets on average. 2) The impact on stock market depth and liquidity is nonlinear: it is stronger in countries where corporate information is more transparent. 3) There is evidence of a significant heterogeneity among countries: contractual savings have a stronger impact on securities markets in countries where the financial system is market based, pension fund contributions are mandatory, and international transactions in securities are lower. 4) The authors do not find that the impact of contractual savings institutions on securities markets is explained by the overall level of development...

Aden has a number of widely recognized unique assets, which are critical inputs to its emerging strategic positioning within Yemen and the region. Most notable is its natural deep-water harbor on the Red Sea, striking landscapes and distinctive topography, abundance of raw materials, and rich urban heritage. In addition, the residents of Aden are known for their hospitable nature and openness to diversity. Today, leadership in Aden, both public and private, are motivated to create prosperity. Despite a broad portfolio of assets and existence of key infrastructure, the city must address constraints that are holding back economic growth. Aden has much of the basic infrastructure required for businesses to compete, with a few areas requiring major investment. The city is spread across 6,980 square kilometers and is composed of eight districts, each with its own commercial center. The city developed on a peninsula and subsequently expanded along the coast, following the main radial route inland. The city of Aden is differentiated from the rest of the country in several important ways. First...

While the 2008 financial crisis is global in nature, it is likely to have heterogeneous welfare impacts within the developing world, with some countries, and some people, more vulnerable than others. It also threatens to have lasting impacts for some of those affected, notably through the nutrition and schooling of children in poor families. These features point to the need for a differentiated social policy response, aiming to provide rapid income support to those in most need, while preserving the key physical and human assets of poor people and their communities. The paper points out some mistakes in past crisis responses and identifies key design features for safety net programs that can help compensate for the likely welfare losses in the short-term while also promoting longer-term recovery.

With the recent resurgence of interest in equity, inequality, and growth, the possibility of a negative relationship between inequality and economic growth, has received renewed interest in the literature. Faced with the prospect that high levels of inequality may persist, and give rise to poverty traps, policymakers are paying more attention to the distributional implications of macroeconomic policies. Because high levels of inequality may hurt overall growth, policymakers are exploring measures to promote growth and equity at the same time. How the consequences of inequality are analyzed, along with the possible cures, depends partly on how inequality is measured. The authors use assets (land) rather than income - and a GMM estimator - to examine the robustness of the relationship between inequality and growth that has been observed in the cross-sectional literature, but has been drawn into question by recent studies using panel techniques. They find evidence that asset inequality - but not income inequality - has a relatively large negative impact on growth. They also find that a highly unequal distribution of assets reduces the effectiveness of educational interventions. This means that policymakers should be more concerned about households' access to assets...

Longstanding macroeconomic instability, and inflation in Turkey, have discouraged investment in financial assets, and a persistently high public sector borrowing requirement has crowded funding for the private sector. Notwithstanding, the Government's ongoing stabilization, and structural reforms, are improving the prospects for the development of financial services, though a series of policy issues should be addressed. This study identifies such issues, and formulates recommendations to better address them. Chapter I outlines the advantages of a broad based, diversified financial services industry, lays out the evidence of a clear correlation between financial system development, and per capita income, and, analyzes the outlook for such financial services industry over the next five years. Chapter II, in addressing the mobilization of savings, describes the extent to which macroeconomic uncertainty, chronically high inflation, and ill-suited tax policies have driven significant savings into real estate, gold...

In an earlier paper, the authors presented a mathematical exposition of a theory that demonstrated that mass privatization without institutions to limit asset-stripping may not lead to a demand for the rule of law ["After the Big Bang? Obstacles to the Emergence of the Rule of Law in Post-Communist Societies," American Economic Review 94(3), June 2004, pages 753-63]. This report makes the same argument in terms of simple diagrams. The central idea is that economic actions (to build value or strip assets) and political positions of individuals are interdependent. "Big bang" privatization may give individuals an interest in taking what they can quickly, rather than waiting for the establishment of property rights protection that would permit them to build more valuable assets. Asset stripping gives some of these individuals an interest in prolonging the absence of the rule of law so that they can enjoy the fruits of stripping without the constraint of government enforcement of property rights. Each individual...

Control of corporate assets by wealthy families in economies lacking institutional integrity is common. It has negative implications on corporate governance and adverse macroeconomic effects when it extends across a sufficiently large part of the country's corporate sector. The authors consider the reasons why family control and control pyramids predominate in emerging market economies and in some industrial economies. They also discuss the reasons why widely held freestanding firms predominate in the United States. The authors discuss policies that countries might adopt to discourage family control pyramids, but caution that control pyramids are but one feature of an institutionally deficient economy. A concerted effort to improve a country's institutions is needed before diffuse ownership is desirable.

Government of Azerbaijan (GoA) and the World Bank have a long history of partnership in addressing the needs of Internally Displaced Persons (IDPs) in the country. The purpose of this study was to start identifying gaps and areas for further engagement. The report would not have been possible without the support of GoA counterparts. The report pursues the argument that in order to expand the choice of IDP livelihoods it is possible to build upon and extend economic activities in which they are already involved and which are currently unprofitable. Indeed, the report shows that many IDPs do seek to supplement their household incomes through a range of strategies but, due to a series of constraints, these strategies neither provide a viable employment source nor bring in substantial incomes. The report concludes that, two decades after their forced displacement, the IDPs' economic and social development still lagged behind that of the rest of the non-displaced population, and they needed continued support. Therefore...

The paper explores whether one of the largest programs in the world for women's empowerment and rural livelihoods, the Indira Kranti Patham in Andhra Pradesh, India, has had an impact on the economic and social wellbeing of households that participate in the program. The analysis usespanel data for 4,250 households from two rounds of a survey conducted in 2004 and 2008 in five districts. Propensity score matching was used to construct control groups and outcomes are compared with differences-in-differences. There are two major impacts. First, the Indira Kranti Patham program increased participants' access to loans, which allowed them to accumulate some assets (livestock and durables for the poorest and nonfarm assets for the poor), invest in education, and increase total expenditures (for the poorest and poor). Women who participated in the program had more freedom to go places and were less afraid to disagree with their husbands; the women participated more in village meetings and their children were slightly more likely to attend school. Consistent with the emphasis of the program on the poor...
