Genetic Algorithm Based Model In Text Steganography, Christine K. Mulunda, Peter W. Wagacha, Alfayo O. Adede
The African Journal of Information Systems
Steganography is an ancient art. It is used for security in open systems. It focuses on hiding secret messages inside a cover medium. The most important property of a cover medium is the amount of data that can be stored inside it without changing its noticeable properties. There are many sophisticated techniques with which to hide, analyze, and recover that hidden information. This paper discusses an exploration in the use of Genetic Algorithm operators on the cover medium. We worked with text as the cover medium with the aim of increasing robustness and capacity of hidden data. Elitism is used …

The Role Of Central Bank Of Nigeria’S Analytical Balance Sheet And Monetary Survey In Monetary Policy Implementation, Sani I. Doguwa, Sunday N. Essien
The Role Of Central Bank Of Nigeria’S Analytical Balance Sheet And Monetary Survey In Monetary Policy Implementation, Sani I. Doguwa, Sunday N. Essien
CBN Journal of Applied Statistics (JAS)
This paper discusses the significance of Central Bank of Nigeria’s (CBN) monetary aggregates in the implementation of monetary policy. The Analytical Balance Sheet and monetary survey are shown to be useful tools in the analysis of monetary and credit developments in the economy. It also discusses the role of the aggregates in monetary policy implementation through the adjusted money multiplier, which explains how policy actions of the CBN influence the broad money supply. Finally, the paper attempts to estimate the Taylor-type monetary policy reaction function for Nigeria using the monetary policy rate and reserve money since December 2006 when the …
The Relationship Between Domestic Savings And Investment: The Feldstein-Horioka Test Using Nigerian Data, Inuwa Nasiru, Usman M. Haruna
The Relationship Between Domestic Savings And Investment: The Feldstein-Horioka Test Using Nigerian Data, Inuwa Nasiru, Usman M. Haruna
CBN Journal of Applied Statistics (JAS)
This study explores the relationship between savings and investment in Nigeria during the period 1980-2011. Unlike previous studies, this study employed Autoregressive Distributed Lag (ARDL) Bounds testing approach to test for long run relationship. The short-run dynamics are also captured from error correction model (ECM).The results of the Bounds test suggest that there is a long run relationship between savings and investment. This result is consistent with a number of earlier studies reviewed in the literature that found saving and investment to be cointegrated in the long run. The results also support the Feldstein-Horioka (1980) hypothesis that postulates low capital …
On The Derivation Of Estimators Of Foster-Greer-Thorbecke (Fgt) Poverty Indices, Oyedeji I. Osowole, Adebayo T. Bamiduro
On The Derivation Of Estimators Of Foster-Greer-Thorbecke (Fgt) Poverty Indices, Oyedeji I. Osowole, Adebayo T. Bamiduro
CBN Journal of Applied Statistics (JAS)
Poverty analysis has relied heavily on data in summarized form and this has created dearth of knowledge on the statistical properties of Foster-Greer-Thorbecke (FGT) poverty indices. This study derived estimators of FGT poverty indices from first principles in an attempt to provide an insight into some intrinsic characteristics of FGT indices. The estimators are found to be reasonably unbiased and consistent. The estimates of the indices obtained from the estimators are approximately 53%, 22% and 12% for the head count, poverty gap and square poverty gap indices. From the conventional method, the estimates are approximately 52%, 21% and 11% respectively. …
Monetary Policy Rule: A Broad Monetary Conditions Index For Nigeria, Yaaba N. Baba
Monetary Policy Rule: A Broad Monetary Conditions Index For Nigeria, Yaaba N. Baba
CBN Journal of Applied Statistics (JAS)
To determine the relative importance of both the domestic and external influences on monetary policy formulation, this paper constructs a broad monetary conditions index for Nigeria. It brings together the three key channels of monetary transmission, namely interest rate, exchange rate and credit channels. The result gives dominance to exchange rate channel, followed by credit channel and interest rate channel. The resultant monetary conditions index traces fairly well the policy direction of the Central Bank of Nigeria for the studied period, hence can serve as an adequate gauge of monetary policy stance of the Bank.
Measuring Technical Efficiency Of Wireless And Wired Technologies In Nigeria Cyber Cafés, Sule Magaji, Eke I. Chukwuemeka
Measuring Technical Efficiency Of Wireless And Wired Technologies In Nigeria Cyber Cafés, Sule Magaji, Eke I. Chukwuemeka
CBN Journal of Applied Statistics (JAS)
This study examined the technical efficiency (TE) of two different remote internet access methods, wireless and wired in Nigeria using the stochastic frontier production function analysis. Primary data were obtained through the use of a set of questionnaire from four hundred and fifty representative samples of cyber café operators. The results show that in Nigeria, in spite of the acclaimed superiority of wireless technologies internationally, wired technology (within the context of Nigeria’s socio-economic constraints) is (still) more efficient technically with mean technical efficient indices of 0.914 and 0.797 respectively. The analysis also suggests that age and years of education of …
Exchange–Rates Volatility In Nigeria: Application Of Garch Models With Exogenous Break, Bala A. Dahiru, Joseph O. Asemota
Exchange–Rates Volatility In Nigeria: Application Of Garch Models With Exogenous Break, Bala A. Dahiru, Joseph O. Asemota
CBN Journal of Applied Statistics (JAS)
This paper examines exchange–rate volatility with GARCH models using monthly exchange–rate return series from 1985:1 to 2011:7 for Naira/US dollar return and from 2004:1 to 2011:7 for Naira/British Pounds and Naira/Euro returns. The study compare estimates of variants of GARCH models with break in respect of the US dollar rates with exogenously determined break points. Our results reveal presence of volatility in the three currencies and equally indicate that most of the asymmetric models rejected the existence of a leverage effect except for models with volatility break. Evaluating the models through standard information criteria, volatility persistence and the log likelihood …
Effect Of Monetary-Fiscal Policies Interaction On Price And Output Growth In Nigeria, Musa Yakubu, Asar K. Barfour, Shehu U. Gulumbe
Effect Of Monetary-Fiscal Policies Interaction On Price And Output Growth In Nigeria, Musa Yakubu, Asar K. Barfour, Shehu U. Gulumbe
CBN Journal of Applied Statistics (JAS)
This paper investigates the effectiveness of monetary-fiscal policies interaction on price and output growth in Nigeria. The dynamic correlations of variables have been captured by the analyses of impulse response and variance decomposition. From innovation analyses, the results suggest that the policy variables money supply and government revenue have more positive impact on price and economic growth in Nigeria specifically in the long run, thus some time with lag. Although monetary and fiscal policy variables have a dominant effect on economic activity, it is clear from this study that economic activity is dominated by its own dynamics in most of …

Quantifying The Impacts Of The Recent Economic Crisis On Regional Tourism Industry And Economy, Yun Ying Zhong, Tadayuki Hara Ph.D.
Hospitality Review
The purpose of this study is to explore the accuracy issue of the Input-Output model in quantifying the impacts of the 2007 economic crisis on a local tourism industry and economy. Though the model has been used in the tourism impact analysis, its estimation accuracy is rarely verified empirically. The Metro Orlando area in Florida is investigated as an empirical study, and the negative change in visitor expenditure between 2007 and 2008 is taken as the direct shock. The total impacts are assessed in terms of output and employment, and are compared with the actual data. This study finds that …
Best Management Practices In Green Lodging Defined And Explained, Leonard Anthony Jackson
Best Management Practices In Green Lodging Defined And Explained, Leonard Anthony Jackson
Hospitality Review
Best management practices in green lodging are sustainable or “green” business strategies designed to enhance the lodging product from the perspective of owners, operators and guests. For guests, these practices should enhance their experience while for owners and operators, generate positive returns on investments. Best management practices in green lodging typically starts with a clear understanding of each lodging firm’s role in society, its impact on the environment and strategies developed to mitigate negative environmental externalities generated from the production of lodging goods and services. Negative externalities of hotel operations manifest themselves in energy and water usage, waste generation and …
Hybrid Spread-Spectrum Tcp For Combating Fraudulent Cyber Activities Against Reconnaissance Attacks, Simon Enoch Yusuf, Olumide Longe
Hybrid Spread-Spectrum Tcp For Combating Fraudulent Cyber Activities Against Reconnaissance Attacks, Simon Enoch Yusuf, Olumide Longe
The African Journal of Information Systems
The inefficiencies of current intrusion detection system against fraudulent cyber activities attracts the attention of computer gurus, also known as “hackers” to exploit known weakness on a particular host or network. These hackers are expert programmers who mainly focus on how the Internet works, and they interact with each other to know its strengths and weaknesses. Then they develop advanced tools which an average attacker with little background can use to know the liveness, reachability and running service on the network. Once an attacker identifies these details, he can accurately launch an effective attack and get maximum benefit out of …

Towards A “Cloud Curriculum” In Art And Science?, Roger Malina
Towards A “Cloud Curriculum” In Art And Science?, Roger Malina
The STEAM Journal
Recently an email hit my desk from Paul Thomas in Australia with a proposal to work together on a “Cloud Curriculum for Art and Science”. I immediately agreed to collaborate. I don’t yet have a clue of what a cloud curriculum is, but what I do know is that we are ‘backing into the future’ in educational institutions and we desperately need a ‘cloud curriculum.’ We need to look over the ten year horizon. And in the emerging art-science field I doubt that the usual approach to curriculum development will work.

A Profile Of Travelers Who Are Willing To Stay In Environmentally Friendly Hotel, Michelle Millar, Karl J. Mayer
Hospitality Review
The purpose of this study is to describe travelers that have indicated they are willing to stay in green hotel in order to better understand the market segment. There is very little knowledge about these types of travelers, thus making it difficult for hoteliers to know how to create marketing campaigns that target them. Data were collected via an online survey company. Behavior characteristics provided a more distinguishing profile of the traveler than did demographics or psychographics. Most travelers were willing to pay the same amount for a green hotel as a traditional hotel. Implications, future research, and limitations are …
