Abstract

Social pension and security systems worldwide are experiencing difficulties in maintaining the financing required to provide promised benefits. Despite their economic and political difficulties, many Latin American countries have arguably been more proactive and innovative with the implementation of social security reform than other regions of the world. Suggestions for reform of the Social Security system in Venezuela are provided by integrating many of the same concepts found in other restructurings in Latin America. It is the conclusion of this analysis that, given the political and economic instability of the region, a major overhaul of the existing system is not politically feasible. An incremental approach with minimal disruption is more attainable given the circumstances.

Abstract

This book is an attempt to reflect on what we have learned from financial policies and financial crises in Latin America. The 21 chapters in this volume capture the developments in various ways. They cover theoretical contributions, regional empirical studies, and specific inquiries on Argentina, Brazil, Chile, Colombia, Cuba, Ecuador, Mexico, Peru and Venezuela. The breadth of methodologies implemented suggests that researchers are looking at Latin American financial markets through a variety of lenses. The chapters are divided into 7 parts, including, in Part I, an initial overview. Part II examines the foreign exchange markets in Latin America and their interactions with other markets. Part III discusses dollarization issues in the region. Part IV then takes up the issue of banking in Latin America. Equity and bond markets are considered in Parts V and VI, respectively. Lastly, Part VII considers pension systems in Latin America. Taken as a whole, the 21 chapters seize the excitement of studying Latin America and provide lessons that are applicable around the world.

Abstract

Purpose

The purpose of this paper is to provide an integrated semantic information retrieval (IR) solution based on an ontology-improved vector space model for situations where a digital collection is established or curated. It aims to create a retrieval approach which could return the results by meanings rather than by keywords.

Design/methodology/approach

In this paper, the authors propose a semantic term frequency algorithm to create a semantic vector space model (SeVSM) based on ontology. To support the calculation, a multi-branches tree model is created to represent the ontology and a set of algorithms is developed to operate it. Then, a semantic ontology-based IR system based on the SeVSM model is designed and developed to verify the effectiveness of the proposed model.

Findings

The experimental study using 30 queries from 15 different domains confirms the effectiveness of the SeVSM and the usability of the proposed system. The results demonstrate that the proposed model and system can be a significant exploration to enhance IR in specific domains, such as a digital library and e-commerce.

Originality/value

This research not only creates a semantic retrieval model, but also provides the application approach via designing and developing a semantic retrieval system based on the model. Comparing with most of the current related research, the proposed research studies the whole process of realizing a semantic retrieval.

Abstract

Purpose

The purpose of this paper is to formulate a novel model for enhancing the effectiveness of existing digital forensic readiness (DFR) schemes by leveraging the capabilities of cyber threat information sharing.

Design/methodology/approach

This paper uses a quantitative methodology to identify the most popular cyber threat intelligence (CTI) elements and introduces a lightweight approach to correlate those with potential forensic value, resulting in the quick and accurate triaging and identification of patterns of malicious activities.

Findings

While threat intelligence exchange steadily becomes a common practice for the prevention or detection of security incidents, the proposed approach highlights its usefulness for the digital forensics (DF) domain.

Originality/value

The proposed model can help organizations to improve their DFR posture, and thus minimize the time and cost of cybercrime incidents.

Abstract

Purpose

The purpose of this paper is to present a two‐phase approach for designing an efficient tailored but flexible storage solution for resource description framework (RDF) data based on its query workload characteristics.

Design/methodology/approach

The approach consists of two phases. The vertical partitioning phase which aims of reducing the number of join operations in the query evaluation process, while the adjustment phase aims to maintain the efficiency of the performance of the query processing by adapting the underlying schema to cope with the dynamic nature of the query workloads.

Findings

The authors perform comprehensive experiments on two real‐world RDF datasets to demonstrate that the approach is superior to the state‐of‐the‐art techniques in this domain.

Originality/value

The main motivation behind the authors' approach is that several benchmarking studies have recently shown that each RDF dataset requires a tailored table schema in order to achieve efficient performance during query processing. None of the previous approaches have considered this limitation.

Abstract

Describes an approach to real‐time expert systems for integrated network management. Presents an overview of expert systems technology, proceeding to develop the requirements for a real‐time system in network management. Describes a system being developed (1989) by Pacific Bell. Describes NETREX, a prototype real‐time system, aimed at automatically maintaining Pacific Bell′s internal data networks. Concentrates on an application for solving problems with travel tickets in real time.

Abstract

Are we now entering the era of a new type of economy, with new rules? What we perceive is more than just an addition to today’s economics. By removing the effects of distance, and giving more equal access across nations and classes, networks will effectively reengineer our basic economic equations. Electronic networks can provide access to skills, work and commerce at much lower cost, via electronic markets in jobs, products, services and education. At the same time, they introduce new economic behaviour, as a large enough quantitative change becomes a qualitative change. Electronics and optics enable the networking of human capital, expanding its application and accelerating its enrichment via education. So knowledge‐based operations may slowly replace traditional capital‐based assets. Consequently, the conventional process for the creation of wealth with its prerequisites for capital investment is revised:economic value in traditional fixed assets is replaced by “electronic assets”. At the same time, the network effect pushes the market mechanism to its limits, through a step‐change in breadth of access, reduced costs of entry and pace of trading. National differences and national markets, all the trappings and devices of commercial locality, are challenged. In this first of two articles, the initial conditions and the evidence for change are examined and the emergence of a new form of economy, or “tele‐economy”, is reviewed. Following from this, a view of the form of capitalism driving the economic environment – “electronic capitalism” – is put forward. The second article, to be published in a forthcoming issue of foresight, examines the consequences and conclusions on assets, wealth accumulation, national players and the benefits and dangers of a tele‐economy.

Abstract

The task of a document retrieval system is to match a query, perhaps in natural language, against a large number of natural language documents. Neural networks are known to be good pattern matchers. This article describes investigations in implementing a document retrieval system based on a neural network model. It shows that many of the standard strategies of information retrieval are applicable in a neural network model.
