A Multilayer Secured Messaging Protocol For Rest-Based Services, Idongesit Efaemiode Eteng

Journal of International Technology and Information Management

The lack of descriptive language and security guidelines poses a big challenge to implementing security in Representational State Transfer (REST) architecture. There is over reliance on Secure Socket Layer/Transport Layer Security (SSL/TLS), which in recent times has proven to be fallible. Some recent attacks against SSL/TLS include: POODLE, BREACH, CRIME, BEAST, FREAK etc. A secure messaging protocol is implemented in this work. The protocol is further compiled into a reusable library which can be called by other REST services. Using Feature Driven Development (FDD) software methodology, a two layer security protocol was developed. The first layer is a well hardened …

Group Decision-Making, Edward Cook

Theses and Dissertations

The present work explores improvements in group decision-making. It begins with a practical example using state-of-the-art techniques for a complex, high-risk decision. We show how these techniques can reveal a better alternative. Although we created an improved decision process, decision-makers were apt to protect their own organizations instead of the project. This tendency was reduced over the course of the decision-making process but inspired the first conceptual component of this work.

The first concept describes the “Cost of Conflict” that can arise in a group decision, using game theory to represent the non-cooperative approach and comparing the outcome to the …

Forecast Combination With Multiple Models And Expert Correlations, David P. Soule

Theses and Dissertations

Combining multiple forecasts in order to generate a single, more accurate one is a well-known approach. A simple average of forecasts has been found to be robust despite theoretically better approaches, increasing availability in the number of expert forecasts, and improved computational capabilities. The dominance of a simple average is related to the small sample sizes and to the estimation errors associated with more complex methods. We study the role that expert correlation, multiple experts, and their relative forecasting accuracy have on the weight estimation error distribution. The distributions we find are used to identify the conditions when a decision …

Assessment Of Adaptability Of A Supply Chain Trading Agent’S Strategy: Evolutionary Game Theory Approach, Yoon Sang Lee, Riyaz T. Sikora

Journal of International Technology and Information Management

With the increase in the complexity of supply chain management, the use of intelligent agents for automated trading has gained popularity (Collins, Arunachalam, B, et al. 2006). The performance of supply-chain agents depends on not just the market environment (supply and demand patterns) but also on what types of other agents they are competing with. For designers of such agents it is important to ascertain that their agents are robust and can adapt to changing market and competitive environments. However, to date there has not been any work done that assesses the adaptability of a trading agent’s strategy in the …

Bribery And Export Intensity: The Role Of Formal Institutional Constraint Susceptibility, Randika Eramudugoda Gamage

Open Access Theses & Dissertations

This study explores the influence of home country formal institutional constraints on firm bribery payments and export intensity. Distinguishing between forms of formal institutional constraints based on their susceptibility to bribery, this study highlights the different mechanisms through which formal institutional constraints impact export intensity. I propose that highly susceptible formal institutional constraints will behave as incentives leading to increased bribery payments. In contrast, less-susceptible formal institutional constraints will act as an added cost, ex-post to bribery payments, in the bribery-export intensity relationship. These less-susceptible formal institutional constraints will further decrease export intensity. Utilizing a firm-level dataset from 25 countries, …

A Conceptual Framework For Managerial Analysis Under Economic Nationalism And Globalization: A Study Of Japanese Automakers In The Usa, Kanji Kitamura

School of Business: Faculty Publications and Other Works

This chapter qualitatively examines cross-national managerial strategies employed at the Japanese automakers in the context of economic nationalism. It proposes and tests a simple yet versatile conceptual framework by developing existing models and integrating foundational concepts available in literature. Proposed as a tool for comparative analysis on management styles, the framework has two extreme ends of a continuum to capture not only variants of the social realities but also changes of businesses as it shifts between the extremes. The findings suggest that the force of economic nationalism likely affects the Japanese automakers’ growth strategies, and the dynamics of managerial styles …

The Reversal Strategy: A Test Case For An Emerging Market, Hilal Anwar Butt, Mohsin Sadaqat

Business Review

The reversal strategy in the Pakistan Stock Market has shown significant profits for the time period January 1993 - September 2017. The available asset pricing models are unable to link these returns with the risk premium. This paper explores an alternative channel of predicting risk premium. It suggests that reversal profits can be considered as compensation for providing liquidity to the market during times of high volatility. Results reveal that reversal is stronger for illiquid and volatile stocks. Furthermore, firms that show reversal, are cash constrained, have lower return on asset (ROA) and equity (ROE), lesser operating profitability (OP), investment …

An Evaluation Of The Forecast Performance Of Dsge And Var Models: The Case Of A Developing Country, Shahzad Ahmad, Adnan Haider

Business Review

This paper estimates a DSGE model and three versions of VAR models (VARX, BVARX and BVAR) to analyze forecasting performance of these models in context of Pakistan. VAR models and a medium-scale DSGE model are estimated using quarterly data (1980Q4-2017Q2). Expanding window recursive out-of-sample forecasts for GDP growth, call money rate, CPI inflation and percent change in exchange rate are generated and compared over the period 2009Q1-2017Q2. Forecasting performance is analyzed by the comparison of bias and root mean squared errors (RMSE). Analysis of forecasting performance over 1-8 quarters forecast horizon reveals that BVAR model provides relatively better forecast in …

United I Stand: An Investigation Of Power Distance Value And Endorsement Of The Great Man Theory Through American Social Identities, Jeffrey M. Girton

Antioch University Dissertations & Theses

Four decades of research on power distance have been applied to cross-cultural leadership studies on an inter-national level. A quantitative investigation was conducted to analyze a uniquely American narrative of power distance, which was developed through a post-structural epistemology. Using ANTi-History theory, endorsement of the Great Man Theory was argued to be a leadership ethos that is related to American power distance value. The GLOBE project’s Power Distance Subscale, Trompenaars and Hampden-Turner’s Achievement Versus Ascription Scale, and an author-developed scale for self-reported endorsement of the Great Man Theory was deployed to investigate culturally contingent leadership ethos on an intra-national level …

Dynamic Pricing Of Wireless Internet Based On Usage And Stochastically Changing Capacity, Demet Batur, Jennifer K. Ryan, Zhongyuan Zhao, Mehmet C. Vuran

Department of Supply Chain Management and Analytics: Faculty Publications

(1) Problem Definition: Inspired by new developments in dynamic spectrum access, we study the dynamic pricing of wireless Internet access when demand and capacity (bandwidth) are stochastic. (2) Academic / Practical Relevance: The demand for wireless Internet access has increased enormously. However, the spectrum available to wireless service providers is limited. The industry has thus altered conventional license- based spectrum access policies through unlicensed spectrum operations. The additional spectrum obtained through these operations has stochastic capacity. Thus, the pricing of this service by the service provider has novel challenges. The problem considered in this paper is therefore of high practical …
