An Efficient Two Sample Capture-Recapture Model With High Recaptures, Danjuma Jibasen, Yusuf J. Adams

CBN Journal of Applied Statistics (JAS)

This paper proposed an efficient two sample capture-recapture model (Ma) with high recaptures and compared it with the existing models like the model of no factor effect (Mo), behavioral response model (Mb) and the Petersen model (Ms), using simulated data. We found that the Petersen model provides a better estimate of the population size when the observations follow a hypergeometric distribution and the population is overestimated when recapture is high. It was also found that the proposed model provides a better estimator of the population size than the existing ones when the recapture is high. This model is particularly useful …

Causal Relationship Between Stock Market Index And Exchange Rate: Evidence From Nigeria, Abdulrasheed Zubair

CBN Journal of Applied Statistics (JAS)

This paper uses Johansen’s cointegration to test for the possibility of cointegration and Granger-causality to estimate the causal relationship between stock market index and monetary indicators (exchange rate and M2) before and during the global financial crisis for Nigeria, using monthly data for the period 2001–2011. Results suggest absence of long-run relationship before and during the crisis. The Granger-causality tests show a uni-directional causality running from M2 to ASI before the crisis while during the period of the crisis there is absence of causality between the variables. This suggests that ASI show responsiveness to M2. Thus, absence of the direct …

Investigating Chaos In The Nigerian Asset And Resource Management (Arm) Discovery Fund, Ibiyinka A. Fuwape, Samuel T. Ogunjo

CBN Journal of Applied Statistics (JAS)

This paper investigates chaos in a Nigerian mutual fund, Asset and Resource Management Company Limited (ARM) for a period of eleven years. The existence of chaotic signals in the data was identified by the reconstruction of the phase space of the daily closing price of the fund and the delay time was quantified using mutual information function and the embedding dimension by the false nearest neighbours, where the values were identified to be 15 and 20 respectively. The presence of chaotic signals in the ARM data was further confirmed by the correlation dimension method which yielded a dimension of 2.2 …

Modeling The Nigerian Inflation Rates Using Periodogram And Fourier Series Analysis, Chukwuemeka O. Omekara,, Emmanuel J. Ekpenyong, Micheal P. Ekerete

CBN Journal of Applied Statistics (JAS)

This work considers the application of Periodogram and Fourier Series Analysis to model all-items monthly inflation rates in Nigeria from 2003 to 2011. The main objectives are to identify inflation cycles, fit a suitable model to the data and make forecasts of future values. To achieve these objectives, monthly all-items inflation rates for the period were obtained from the Central Bank of Nigeria (CBN) website. Periodogram and Fourier series methods of analysis are used to analyze the data. Based on the analysis, it was found that inflation cycle within the period was fifty one (51) months, which coincides with the …

Nigerian Stock Index: A Search For Optimal Garch Model Using High Frequency Data, Olaoluwa Simon Yaya

CBN Journal of Applied Statistics (JAS)

This paper attempts to fit the best Generalized Autoregressive Conditional Heteroscedastic (GARCH) model for All Share Index (ASI) of Nigerian Stock Exchange (NSE) returns. A search is made on various GARCH variants specified on the assumptions of stationarity and asymmetry. Fractionally integrated types are also considered to capture the possibility of return series having property of long range dependency. The parameter estimations are carried out on the assumptions of normality and non-normality of GARCH innovations, with models and forecasts evaluated using information criteria and loss functions respectively. Under normality assumption, Hyperbolic GARCH (HYGARCH(1,d,1)) model is selected and Integrated GARCH (IGARCH(1,1)) …

Time Series Modeling Of Nigeria External Reserves, Iheanyichukwu S. Iwueze, Eleazar C. Nwogu, Valentine U. Nlebedim

CBN Journal of Applied Statistics (JAS)

This paper discusses the levels and trend of external reserves in Nigeria. The relevance of this lies in the fact that it could help to monitor the reserves and throw early warning signal about any economic crisis. Monthly data on Nigeria external reserves for the period January 1999 to December, 2008 derived from the 2008 CBN Statistical Bulletin was analyzed using ARIMA model. Results of the analyses show that (i) the data requires logarithmic transformation to stabilize the variance and make the distribution normal (ii) the appropriate model that best describes the pattern in the transformed data is the Autoregressive- …

A Markov Decision Process Approach To Optimal Control Of A Multi-Level Hierarchical Manpower System, Akaninyene U. Udom

CBN Journal of Applied Statistics (JAS)

A recurrent problem in manpower control is how to attain the desired structural configuration in an optimal way, since it is possible to reach a desired structural configuration using different control inputs. The major aim of this paper is to develop a Markov Decision Process for optimal control of a Multi-level Hierarchical Manpower System (MHMS) by promotion and interdepartmental transfers. This is examined under control by intervention and contraction cost Markov Decision Process.

Carton Clamp Methodologies And The Effects On Load Containment And Retention, Tyler D. Blumer

Master's Theses

ABSTRACT

Carton Clamp Test Methodologies and the Effects on

Load Containment and Retention

Tyler Don Blumer

A carton clamp is an alternative device for moving packages and material. Instead of using iron tines like that of a conventional forklift, a carton clamp uses two large aluminum platens to slightly compress and secure the load for handling. This is advantageous as it allows operators to move layers of a unitized load individually, and eliminates the need for a pallet when handling full unitized loads. When using a carton clamp attachment, it is often difficult for operators to accurately gauge the amount …

Agco Corporation Valuation, Sean Michael Miller

Undergraduate Honors Capstone Projects

This paper will discuss the excellent growth potential that AGCO Corporation faces and the reason that this company's stock is rated as a hold position. AGCO has seen tremendous progress and is in an industry that shows that a growing world population will continue to need food and more efficient ways to create food. However, based on sensitivities of assumptions in the models presented herein and on a current share price that is already close to my assumed fair value I do not issue a buy recommendation.

Titanic: Consuming The Myths And Meanings Of An Ambiguous Brand, Stephen Brown, Pierre Mcdonagh, Clifford J. Shultz

School of Business: Faculty Publications and Other Works

Myths have come of age in consumer research. In the 22 years since Levy’s inaugural article, the literature has grown at an impressive rate. Yet important questions remain unanswered: What makes some myths especially meaningful to consumers? Why are certain consumer myths more prevalent and less perishable than others? This article argues that ambiguity is an influential factor. Using the RMS Titanic as an empirical exemplar, it unpacks the principal forms of myth-informed ambiguity surrounding “the unsinkable brand.” Predicated on William Empson’s hitherto unsung principles of literary criticism, the article posits that ambiguity in its multifaceted forms is integral to …

New Mouthguard Design With Intermediate Nickel-Titanium And Foam Layer, Freddie Martinez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mouthguards help prevent orofacial injuries in many physical activities, commonly to the maxillary incisors. Mouthguards have many different properties which can be idealized. One property involves the amount of impact force the mouthguard can dissipate, commonly referred to as shock absorption. The aim of this study was to improve shock absorption capabilities beyond the protection that a mouthguard made of Ethylene Vinyl Acetate (EVA) can offer. A Nickel-Titanium (NiTi) and/or foam intermediate layer was placed between EVA. Seven configurations were fabricated at 3 different thicknesses. The configurations consisted of an intermediate layer composed of NiTi, foam, or NiTi/foam. The NiTi …

Followership, Leadership And Social Influence, Burak Oc, Michael R. Bashshur

Research Collection Lee Kong Chian School Of Business

Traditional research in leadership has largely relegated followers to the role of passive recipients or, at best, moderators of leader influence and behaviors. However, recent work in the area of followership has begun shifting this focus and emphasizing the possibility that followers actively have an influence over leaders, in particular leader behavior. This paper revisits traditional areas of the leadership literature and builds on the emerging followership literature to reintroduce followers as part of the social context of leaders. In an attempt to build theoretical rationales for how followers influence leader behavior we draw on the social influence (e.g., Social …

The Costs Of Ambient Cultural Disharmony: Indirect Intercultural Conflicts In Social Environment Undermine Creativity, Roy Y. J. Chua

Research Collection Lee Kong Chian School Of Business

Intercultural tensions and conflicts are inevitable in the global workplace. This paper introduces the concept of ambient cultural disharmony—indirect experience of intercultural tensions and conflicts in individuals' immediate social environment—and demonstrates how it undermines creative thinking in tasks that draw on knowledge from multiple cultures. Three studies (a network survey and two experiments) found that ambient cultural disharmony decreases individuals' effectiveness at connecting ideas from disparate cultures. Beliefs that ideas from different cultures are incompatible mediate the relationship between ambient cultural disharmony and creativity. Alternative mechanisms such as negative affect and cognitive disruption were not viable mediators. Although ambient cultural …

Financial Reporting Quality Of Chinese Reverse Merger Firms: The Reverse Merger Effect Or The China Effect?, Kun-Chih Chen, Qiang Cheng, Ying Chou Lin, Yu-Chen Lin, Xing Xiao

Research Collection School Of Accountancy

In this paper, we examine why Chinese reverse merger (RM) firms have lower financial reporting quality. We find that while U.S. RM firms have similar financial reporting quality as matched U.S. IPO firms, Chinese RM firms exhibit lower financial reporting quality than Chinese ADR firms. We further find that Chinese RM firms exhibit lower financial reporting quality than U.S. RM firms. These results indicate that the use of RM process is associated with poor financial reporting quality only in firms from China, where the legal enforcement is weaker than U.S. In addition, we find that compared to Chinese ADR firms, …

Institutional Presence, Johan Sulaeman, Chi Shen Wei

Research Collection Lee Kong Chian School Of Business

We propose an Institutional Presence (IP) measure to capture the latent role of non-owner institutional investors who nevertheless may be observing a firm. We employ this measure to examine whether the ‘presence’ of institutional investors reduces information asymmetry in the market. Firms in areas with high institutional presence experience higher liquidity, faster information incorporation, lower costs of equity capital, and less financing frictions relative to firms in low IP areas. The results hold after controlling for firm and geographical characteristics including institutional ownership and urban locality. Our findings indicate that being in the presence of institutional investors brings tangible benefits.

In Search Of The Impactful And The Interesting: Swings Of The Pendulum?, Timothy Adrian Robert Clark, Steven W. Floyd, Mike Wright

Research Collection Lee Kong Chian School Of Business

In this article we reflect on our time as editors of JMS during the period 2003-09. First we describe the context as we saw it on assuming editorship of the Journal and the actions that we took to improve the quality of scholarship published in the journal in order to set JMS on the trajectory to become a world-leading Journal. We articulate our view of what quality means in this context and observe that we eschewed the USA-Europe divide. Rather, to be publishable, all papers had to meet the highest standards relative to their epistemological assumptions. Finally, we address two …

Contrasting Perspectives On China's Rare Earths Policies: Reframing The Debate Through A Stakeholder Lens, Leslie Hayes-Labruto, Simon J.D. Schillebeeckx, Mark Workman, Nilay Shah

Research Collection Lee Kong Chian School Of Business

This article critically compares China's rare earth policy with perspectives upheld in the rest of the world (ROW). We introduce rare earth elements and their importance for energy and present how China and the ROW are framing the policy debate. We find strongly dissonant views with regards to motives for foreign direct investment, China's two-tiered pricing structure and its questionable innovation potential. Using the metaphor of "China Inc.", we compare the Chinese government to a socially responsible corporation that aims to balance the needs of its internal stakeholders with the demands from a resource-dependent world. We find that China's internal …

Energy Development In Africa And The Performance Of Renewable Energy Projects, Yohannes Haile

Student Scholarship

Africa has abundant energy resources; however, it is estimated that no more than 30% of its population has access to reliable and sustainable grid electricity. Furthermore, only 50% of the countries in Sub-Saharan Africa (SSA) are expected to have universal access to electricity by 2050. Literatures identify affordability, financing mechanisms, and policy instruments as key factors for the performance of renewable energy projects. Our research data has revealed that the performance of renewable energy systems cannot be viewed or determined in isolation (contextual reduction) from the social system of the host community. Furthermore, the performance of renewable energy projects is …

The Impact Of Securitization, Bank Liquidity Shocks, And Government Intervention On Lending And Banks' Asset Composition: Evidence From The U.S. 2007-2009 Financial Crisis, Peter V. Egly

Theses and Dissertations - UTB/UTPA

The 2007- 2009 financial crisis creates a new wave of research opportunities in part due to the transformation of the banking system that led to the development of securitized banking that is supported by short term funding sources provided through the money and capital markets. The near collapse of the financial system ultimately led to the ensuing government intervention by the Federal Reserve and the U.S. Treasury department to revive the frail U.S. economy. This dissertation has two basic research objectives: 1) investigate the impact of securitization and the subprime mortgage collapse on bank lending during the crisis and 2) …

Canadian Family Leisure, Family Functioning, And Family Satisfaction: A Family Perspective, Shaun C. Nua

Theses and Dissertations

The purpose of this study was to further examine the relationship between family leisure variables and the dependent variables of family functioning and satisfaction with family life among a broad, national sample of Canadian families using the Core and Balance framework. Specifically, this study examined how both family leisure involvement (core and balance) and family leisure satisfaction contributed to the explanation of variance in family functioning and satisfaction with family life. Because the data were nested in families, this study accounted for family-level variance by incorporating mixed modeling. The sample consisted of 943 families across Canada including one parent and …

The Mechanisms Of Interpersonal Privacy In Social Networking Websites: A Study Of Subconscious Processes, Social Network Analysis, And Fear Of Social Exclusion, Bryan I. Hammer

Graduate Theses and Dissertations

With increasing usage of Social networking sites like Facebook there is a need to study privacy. Previous research has placed more emphasis on outcome-oriented contexts, such as e-commerce sites. In process-oriented contexts, like Facebook, privacy has become a source of conflict for users. The majority of architectural privacy (e.g. privacy policies, website mechanisms) enables the relationship between a user and business, focusing on the institutional privacy concern and trust; however, architectural privacy mechanisms that enables relationships between and among users is lacking. This leaves users the responsibility to manage privacy for their interpersonal relationships. This research focuses on the following …

Consumer Adoption Of Health Information Systems, Sankara Subramanian Srinivasan

Graduate Theses and Dissertations

At nearly 18 percent of the country's GDP, the U.S. healthcare industry continues to wrestle with growing cost and a quality of care that does not match the increased spending. The dominant focus to date has been on promoting Health IT (HIT) system implementation and digitizing health records at the provider's end, with scant attention to the role of the patient in the healthcare process. The source of inefficiency in the healthcare system is not only on account of shortcomings at the provider's end but also due to non-compliance (such as failing to adhere to medication advice and follow-up visits) …

Management Forecast Credibility And Underreaction To News, Jeffrey Ng, Irem Tuna, Rodrigo Verdi

Research Collection School Of Accountancy

In this paper, we first document evidence of underreaction to management forecast news. We then hypothesize that the credibility of the forecast influences the magnitude of this underreaction. Relying on evidence that more credible forecasts are associated with a larger reaction in the short window around the management forecasts and a smaller post-management forecast drift in returns, we show that the magnitude of the underreaction is smaller for firms that provide more credible forecasts. Our paper contributes to the literature by providing out-of-sample evidence of the drift in returns documented in the post-earnings-announcement drift literature, with the credibility of the …

Counterparty Responses To Managerial Overconfidence, Paul Hribar, Jaewon Kim, Ryan Wilson, Holly I-Hwa Yang

Research Collection School Of Accountancy

Existing research links CEO overconfidence to a number of corporate decisions including overinvestment, external acquisitions, and earnings management. These findings raise the question of whether counterparties distinguish between differences in CEOs, and how they respond to it. We focus on two key counterparties – auditors and credit rating agencies – and examine whether audit fees and credit ratings are affected by CEO overconfidence. We find a positive association between audit fees and CEO overconfidence, suggesting that auditors exert more effort or increase the risk premium associated with auditing firms with more overconfident CEOs. We also find a significant negative association …
