Application Of Web Mashup Technology To Oyster Information Services, Christian Chuindja Ngniah

University of New Orleans Theses and Dissertations

Web mashup is a lightweight technology used to integrate data from remote sources without direct access to their databases. As a data consumer, a Web mashup application creates new contents by retrieving data through the Web application programming interface (API) provided by the external sources. As a data provider, the service program publishes its Web API and implements the specified functions.

In the project reported by this thesis, we have implemented two Web mashup applications to enhance the Web site oystersentinel.org: the Perkinsus marinus model and the Oil Spill model. Each model overlay geospatial data from a local database …

Diseñando Colisiones De Satélites En La Guerra Cibernética Encubierta, Jan Kallberg

Jan Kallberg

La guerra concentrada en la red depende de la red de información global para capacidades de combate conjuntas.3 La capa fundamental crea la capacidad de combate global como la columna vertebral espacial de la red de información donde los haberes espaciales son el elemento decisivo. EE.UU. depende de las capacidades espaciales para su éxito y la seguridad nacional de EE.UU. se basa hoy en día en un número limitado de satélites muy utilizados. Estos satélites son cruciales para la disuasión estratégica, la vigilancia, la recopilación de inteligencia y las comunicaciones militares. Si la disuasión estratégica falla, los satélites forman parte …

Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns

MIS/OM/DS Faculty Publications

We examine the effects of human resource management (HRM) practices (e.g., career development, social support, compensation, and security) on IT professionals‟ job search behavior. Job search is a relatively novel dependent variable in studies of voluntary withdrawal behavior, in general, and for IT professionals, in particular. From a universalistic perspective, HRM practices individually and in combination exhibit independently additive effects on job search behavior. Our study contrasts this perspective with configurational theory, hypothesizing that proposed idealtype configurations of HRM practices have synergistic effects on job search behavior. We contribute to the IT and broader HRM literature by theoretically explicating and …

The Return Of Dr. Strangelove: How Austerity Makes Us Stop Worrying And Love The Bomb…And Cyber War, Jan Kallberg, Adam Lowther

Jan Kallberg

With sequestration looming—generating significant cuts to defense spending—the United States may find itself increasingly relying on nuclear and cyber deterrence as an affordable way to guarantee national sovereignty and prevent major conflict. While earlier defense planning and acquisitions were based on economic conditions that no longer exist, Congress’ options to balance the budget by cutting defense spending are politically palatable because far fewer American are “defense voters” than “social welfare voters,” according to a number of recent public opinion surveys.

Analysis - Toward A New American Military., Adam Lowther, Jan Kallberg

Jan Kallberg

In releasing the United States Department of Defense’s (DoD) Sustaining U.S. Global Leadership: Priorities for 21st Century Defense and Defense Budget Priorities and Choices in January 2012, President Barack Obama and Secretary of Defense Leon Panetta offered a rationale for the administration’s reductions in defense spending. By stating that the shift in strategic direction is an effort to “put our fiscal house in order” and a response to the 2011 Budget Control Act, which requires DoD to reduce spending by $487 billion between fiscal years 2012 and 2021, the United States’ NATO partners in Europe were given considerable reason for …

Principles For Conducting Critical Realist Case Study Research In Information Systems, Donald E. Wynn, Clay K. Williams

MIS/OM/DS Faculty Publications

Critical realism is emerging as a viable philosophical paradigm for conducting social science research, and has been proposed as an alternative to the more prevalent paradigms of positivism and interpretivism. Few papers, however, have offered clear guidance for applying this philosophy to actual research methodologies. Under critical realism, a causal explanation for a given phenomenon is inferred by explicitly identifying the means by which structural entities and contextual conditions interact to generate a given set of events. Consistent with this view of causality, we propose a set of methodological principles for conducting and evaluating critical realism-based explanatory case study research …

With the prospect of sequestration looming, the United States may find itself increasingly rely ing on nuclear and cy ber deterrence as an affordable means of guaranteeing national sovereignty and preventing major conflict between the U.S. and potential adversaries in the Asia-Pacific. While earlier defense planning and acquisition were based on economic conditions that no longer ex ist, Congress’s options to balance the budget by cutting defense spending are politically palatable because far fewer American are “defense v oters” relative to “social welfare voters,” according to a number of recent public opinion surveys. The simple fact is China’s rise has …

Common Criteria Meets Realpolitik Trust, Alliances, And Potential Betrayal, Jan Kallberg

Jan Kallberg

Common Criteria for Information Technology Security Evaluation has the ambition to be a global standard for IT-security certification. The issued certifications are mutually recognized between the signatories of the Common Criteria Recognition Arrangement. The key element in any form of mutual relationships is trust. A question raised in this paper is how far trust can be maintained in Common Criteria when additional signatories enter with conflicting geopolitical interests to earlier signatories. Other issues raised are control over production, the lack of permanent organization in the Common Criteria, which leads to concerns of being able to oversee the actual compliance. As …

Feature-Based Opinion Mining And Ranking, Magdalini Eirinaki, S. Pisal, J. Singh

Magdalini Eirinaki

The proliferation of blogs and social networks presents a new set of challenges and opportunities in the way information is searched and retrieved. Even though facts still play a very important role when information is sought on a topic, opinions have become increasingly important as well. Opinions expressed in blogs and social networks are playing an important role influencing everything from the products people buy to the presidential candidate they support. Thus, there is a need for a new type of search engine which will not only retrieve facts, but will also enable the retrieval of opinions. Such a search …

Towards Cyber Operations The New Role Of Academic Cyber Security Research And Education, Jan Kallberg, Bhavani Thuraisingham

Jan Kallberg

Abstract – The shift towards cyber operations represents a shift not only for the defense establishments worldwide but also cyber security research and education. Traditionally cyber security research and education has been founded on information assurance, expressed in underlying subfields such as forensics, network security, and penetration testing. Cyber security research and education is connected to the homeland security agencies and defense through funding, mutual interest in the outcome of the research, and the potential job market for graduates. The future of cyber security is both defensive information assurance measures and active defense driven information operations that jointly and coordinately …

Geometric Programming Subject To System Of Fuzzy Relation Inequalities, Elyas Shivanian, Mahdi Keshtkar, Esmaile Khorram

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, an optimization model with geometric objective function is presented. Geometric programming is widely used; many objective functions in optimization problems can be analyzed by geometric programming. We often encounter these in resource allocation and structure optimization and technology management, etc. On the other hand, fuzzy relation equalities and inequalities are also used in many areas. We here present a geometric programming model with a monomial objective function subject to the fuzzy relation inequality constraints with maxproduct composition. Simplification operations have been given to accelerate the resolution of the problem by removing the components having no effect on …

Numerical Solution Of Interval And Fuzzy System Of Linear Equations, Suparna Das, S. Chakraverty

Applications and Applied Mathematics: An International Journal (AAM)

A system of linear equations, in general is solved in open literature for crisp unknowns, but in actual case the parameters (coefficients) of the system of linear equations contain uncertainty and are less crisp. The uncertainties may be considered in term of interval or fuzzy number. In this paper, a detail of study of linear simultaneous equations with interval and fuzzy parameter (triangular and trapezoidal) has been performed. New methods have been proposed for solving such systems. First, the methods have been tested for known problems viz. a circuit analysis solved in the literature and the results are found to …

Imagining Emergent Metadata, Realizing The Emergent Web, Jason A. Bengtson

Jason A Bengtson

Current metadata schemas are largely analog technology grafted onto the digital format. They have three inherent limitations that need to be transcended: they generate a static product which must be changed manually, they revolve around the needs of human, rather than mechanistic agents, and they are limited by the imagination and organizational capabilities of human agency. The author argues that to meet future challenges metadata will have to take a more flexible, adaptive form that centers on the needs of the machine in searching, interpretation and organization until the information it proxies enters into the human sphere. The author further …

The Art Of Redirection: Putting Mobile Devices Where You Want Them, Jason A. Bengtson

Jason A Bengtson

Mobile technology has exploded, with many libraries experiencing a surge in access to their resources through mobile devices. In response, many institutions have created or are creating mobile sites designed to accommodate themselves to the unique strictures of these devices. One hurdle faced by these organizations, however, is getting mobile users to those sites. One solution is mobile redirect scripts, which automatically redirect mobile users from a regular page to a mobile page. These scripts come in various forms and present unique challenges to libraries. How are these scripts created? What triggers can or should be used to activate them? …

Stochastic Analysis Of Horizontal Ip Scanning, Derek Leonard, Zhongmei Yao, Xiaoming Wang, Dmitri Loguinov

Computer Science Faculty Publications

Intrusion Detection Systems (IDS) have become ubiquitous in the defense against virus outbreaks, malicious exploits of OS vulnerabilities, and botnet proliferation. As attackers frequently rely on host scanning for reconnaissance leading to penetration, IDS is often tasked with detecting scans and preventing them. However, it is currently unknown how likely an IDS is to detect a given Internet-wide scan pattern and whether there exist sufficiently fast scan techniques that can remain virtually undetectable at large-scale. To address these questions, we propose a simple analytical model for the window-expiration rules of popular IDS tools (i.e., Snort and Bro) and utilize a …

On Superposition Of Heterogeneous Edge Processes In Dynamic Random Graphs, Zhongmei Yao, Daren B. H. Cline, Dmitri Loguinov

Computer Science Faculty Publications

This paper builds a generic modeling framework for analyzing the edge-creation process in dynamic random graphs in which nodes continuously alternate between active and inactive states, which represent churn behavior of modern distributed systems. We prove that despite heterogeneity of node lifetimes, different initial out-degree, non-Poisson arrival/failure dynamics, and complex spatial and temporal dependency among creation of both initial and replacement edges, a superposition of edge-arrival processes to a live node under uniform selection converges to a Poisson process when system size becomes sufficiently large. Due to the convoluted dependency and non-renewal nature of various point processes, this result significantly …

Designer Satellite Collisions From Covert Cyber War, Jan Kallberg

Jan Kallberg

Outer space has enjoyed two decades of fairly peaceful development since the Cold War, but once again it is becoming more competitive and contested, with increased militarization. Therefore, it is important the United States maintain its space superiority to ensure it has the capabilities required by modern warfare for successful operations. Today is different from earlier periods of space development,1 because there is not a blatantly overt arms race in space,2 but instead a covert challenge to US interests in maintaining superiority, resilience, and capability. A finite number of states consider themselves geopolitical actors; however, as long as the United …

Identification Of Influential Social Networkers, Magdalini Eirinaki, S. P. Singh Monga, S. Sundaram

Magdalini Eirinaki

Online social networking is deeply interleaved in today's lifestyle. People come together and build communities to share thoughts, offer suggestions, exchange information, ideas, and opinions. Moreover, social networks often serve as platforms for information dissemination and product placement or promotion through viral marketing. The success rate in this type of marketing could be increased by targeting specific individuals, called 'influential users', having the largest possible reach within an online community. In this paper, we present a method aiming at identifying the influential users within an online social networking application. We introduce ProfileRank, a metric that uses popularity and activity characteristics …

Ancillary Service Capacity Optimization For Both Electric Power Suppliers And Independent System Operator, Lijian Chen, Dengfeng Sun, Guang Li

MIS/OM/DS Faculty Publications

Ancillary Services (AS) in electric power industry are critical to support the transmission of energy from generators to load demands while maintaining reliable operation of transmission systems in accordance with good utility practice. The ancillary services are procured by the independent system operator (ISO) through a process called the market clearing process which can be modeled by the partial equilibrium from the ends of ISO. There are two capacity optimization problems for both Market participants (MP) and Independent System Operator (ISO). For a market participant, the firm needs to determine the capacity allocation plan for various AS to pursue operating …

Irish Cios’ Influence On Technology Innovation And It-Business Alignment, Harvey Enns, Joseph J. Mcdonagh

MIS/OM/DS Faculty Publications

Technology is the driving force behind many of today’s new products, services, and cost-cutting measures. However, there are gaps in our understanding about how technological innovation is fostered and nurtured in organizations.

Part of the answer is to examine how Chief Information Officers (CIOs) exercise influence regarding technological innovation in organizations. This is particularly important since the CIO is the head of technology in organizations, an important source of technological innovation. This article draws on an established executive influence framework to demonstrate how Irish CIOs are able to solidify Information Technology’s (IT’s) contribution to technological innovation via relational means. Most …
