The Influence Of Corporate Social Responsibility On The Decision-Making Process Of Music Festival-Goers: Findings From A Survey-Embedded Experiment, Yahya A. Alzghoul

All Dissertations

The concept of corporate social responsibility (CSR) has received pronounced interest at both the academic and industry levels, associated with the recognition that businesses have responsibilities towards society beyond profit making (Othman & Othman, 2014). The tourism industry relies heavily on environmental and cultural resources within tourist destinations (Sheldon & Park, 2011), requiring businesses to actively engage with social and environmental issues (Henderson, 2007). While there is an increased interest in CSR in the tourism sector at both the academia and business levels, CSR tourism research is underdeveloped (Coles, Fenclova, & Dinan, 2013; Sheldon & Park, 2011; Wells, Smith, Taheri, …

The Evolutionary Diversity Of Uracil Dna Glycosylase Superfamily, Jing Li

All Dissertations

Uracil DNA glycosylase (UDG) is a crucial member in the base excision (BER) pathway that is able to specially recognize and cleave the deaminated DNA bases, including uracil (U), hypoxanthine (inosine, I), xanthine (X) and oxanine (O). Currently, based on the sequence similarity of 3 functional motifs, the UDG superfamily is divided into 6 families. Each family has evolved distinct substrate specificity and properties. In this thesis, I broadened the UDG superfamily by characterization of three new groups of enzymes. In chapter 2, we identified a new subgroup of enzyme in family 3 SMUG1 from Listeria Innocua. This newly found …

Understanding Intracellular Redox Regulation In Methanogens: Characterization Of The Components And Targets Of The Nadph-Dependent Thioredoxin System From Methanosarcina Acetivorans, Addison Clark Mccarver

Graduate Theses and Dissertations

All cells have a reduced intracellular environment. In the presence of oxygen, the non-specific oxidation of intracellular components leads to the production of reactive oxygen species (ROS) within cells leading to oxidative stress. During oxidative stress labile cofactors (e.g. Fe-S clusters) are lost and deleterious disulfide bonds are formed within proteins. Intracellular redox maintenance systems are used to direct reducing equivalents towards the repair of oxidatively-damaged proteins. The thioredoxin system is the ubiquitous intracellular redox system, found in virtually all species. The canonical thioredoxin system is comprised of a NADPH-dependent thioredoxin reductase (TrxR) that functions to reduced thioredoxin (Trx). Although …

Study methods are briefly described and paired with a description of the NWA region as an ideal southern Latino emerging community in which to conduct research on educational outcomes. The manuscript then turns to an ethnographic examination of how and the extent to which curricular, co-curricular and extra-curricular aspects of a Spanish for …

Small Rna-Dependent Gene Silencing In The Green Alga Chlamydomonas Reinhardtii: Functions And Mechanisms, Eun Jeong Kim

School of Biological Sciences: Dissertations, Theses, and Student Research

Small RNAs (sRNAs), ~20-30 nucleotides in length, are non-coding RNAs that play essential roles in the regulation of gene expression in eukaryotes. They lead to inactivation of cognate sequences at the post-transcriptional level via a variety of mechanisms involved in translation inhibition and/or RNA degradation.

In the Chlorophyta Chlamydomonas reinhardtii, however, the molecular machinery responsible for sRNA-mediated translational repression remains unclear. To address the mechanisms of translation inhibition by sRNA, we have isolated an RNAi defective mutant (Mut26), which contains a deletion of the gene encoding the homolog of CCR4 in Chlamydomonas. We investigated the expression …

Resource Allocation For Acorn Production: A Comparison Across Species Pairs Of Oaks With Contrasting Acorn Production Patterns And Water Use Strategies, Kyle A. Funk

School of Biological Sciences: Dissertations, Theses, and Student Research

Mast seeding, or masting, is a phenomenon where inter-annual seed production by individuals is synchronized across a population of plants. Masting is hypothesized to confer a selective advantage to plants by increasing rates of pollination or by decreasing rates of seed predation. Masting can also play a crucial role in ecosystem functioning as fluctuations in annual seed crops correspond with fluctuations in seed predator populations, which in turn have consequences that ripple throughout food webs. The mechanism(s) that causes masting is unresolved, but the high variability in seed production of masting plants is hypothesized to be caused, in part, by …

The Impact Of Private Sector Credit On Economic Growth In Nigeria, Ganiyu B.A. Amoo, Matthew I. Eboreime, Yusuf Adamu, Maximillian C. Belonwu

CBN Journal of Applied Statistics (JAS)

The paper determines empirically the local conditions and policy environment that influence the absorptive capacity of credit in the Nigerian economy for the period 1993:Q1 to 2013:Q4 using fully modified least squares. Findings show that credit is growth-enhancing, even when trade openness, monetary policy, investment climate and infrastructure are low. Also, the composite local condition index analysis revealed that private sector credit increased economic growth when domestic or local conditions were favourable and the absorptive capacity of the domestic economy for credit was estimated at 29% of the GDP in 2013. These results suggest that there is ample room for …

Forecasting The Volatilities Of The Nigeria Stock Market Prices, Sikiru O. Ibrahim

CBN Journal of Applied Statistics (JAS)

The objective of this work is to assess and forecast the volatilities of prices on the Nigeria Stock Exchange. The ARCH family (ARCH, GARCH, TGARCH, EGARCH and PGARCH) and ARIMA models are used to assess and forecast volatilities in prices on the Nigeria stock market. The EGARCH model is found to be the most efficient for forecasting volatilities and has the capability to show the asymmetric effect. The assessment of volatilities in prices for 1985 to 2014 shows clustering, over the years. The forecasting performance shows the volatility in the Nigeria stock market to be on the increase for the …

Determinants Of Fdi And Fpi Volatility: An E-Garch Approach, Philip I. Nwosa, Omolade Adeleke

CBN Journal of Applied Statistics (JAS)

This study examined the determinants of Foreign Direct Investment (FDI) and Foreign Portfolio Investment (FPI) volatility in Nigeria. The study used annual data covering the periods 1986 to 2016 and the EGARCH approach was employed. The study observed that trade openness and world GDP were the significant determinants of FDI volatility, while domestic interest rate and stock market capitalization were significant determinants of FPI volatility in Nigeria. Other variables were insignificant in influencing volatility in FDI and FPI. Consequently, the study recommends the need for the prudent management of these determinants (with particular reference to indigenous variables) to ensure reduced …

Determinants Of Financial Inclusion In Sub-Saharan Africa Countries: Does Institutional Infrastructure Matter?, Kazeem B. Ajide

CBN Journal of Applied Statistics (JAS)

The paper examines the determinants of financial inclusion by specially accounting for the role of institutions in a panel of eighteen (18) subSaharan Africa (SSA) countries using a dynamic system of Generalized Method of Moments (SYS-GMM). The emanated findings consistently stress the importance of institutions together with other control variables like GDP per capita, inflation, bank concentration and z-score as key drivers of FI. In the final analysis, the paper emphasizes the importance of using dimension by dimension indicators of governance as well as a composite governance index instead of relying solely on the latter as a basis of informing …

On The Properties Of The Weibull-Burr Iii Distribution And Its Application To Uncensored And Censored Survival Data, Aliyu Yakubu, Sani I. Doguwa

CBN Journal of Applied Statistics (JAS)

Twelve different families of cumulative distributions that are used to model real life data were introduced by Burr (1942). Burr III distribution is among these families of cumulative distributions. In this work, a four-parameter distribution is introduced to model real life scenarios called Weibull-Burr III distribution. The limiting behavior of the proposed distribution, hazard function, moments, skewness, kurtosis and quantile function is investigated; order statistics and entropy are also derived. The method of Maximum Likelihood Estimation technique was used in estimating the parameters of the proposed distribution. To prove the flexibility and performance of the distribution and Weibull-G family of …

The Consumption-Oriented Capital Asset Pricing Model In The Nigerian Stock Exchange, Abidemi C. Adegboye

CBN Journal of Applied Statistics (JAS)

In this study, the Consumption-oriented Capital Asset Pricing Model (CCAPM) is tested for Nigeria by considering returns on investments in the Nigerian Stock Exchange market and other financial assets for the period 1993: Q1 to 2016:Q4. Three tests are conducted. The first test examines forecast performance of excess returns for the selected portfolios in predicting future consumption; the second test estimates the consumption betas for the set of assets using two alternative formulations of the CCAPM; and the third test included consumption growth variable in a multifactor risk analysis to compare with the basic CAPM formulations. The empirical results indicates …

An Assessment Of The Impact Of Banking Reforms On Economic Growth And Bank Performance In Nigeria, Matthew O. Gidigbi

CBN Journal of Applied Statistics (JAS)

This study assesses the impact of banking reforms on banks’ performance and economic growth for the period 1981 to 2015 by fitting an ANOVA model into Stepwise Regression. Using dummy variables to isolate reform periods, results show that banking reforms contribute positively to economic growth, especially in the period 1999 to 2004. Also, banking reforms are found to contribute negatively to banks’ performance, following the 1993 reforms. The study confirms that banking system reforms in Nigeria have dual impact on the economy and banks’ performance. The banking reforms are capable of promoting growth in the economy. Thus, the study recommends …

A Complete Coverage Algorithm For 3d Structural Inspection Using An Autonomous Unmanned Aerial Vehicle, Venkat Ramana Reddy Garlapati

Student Work

This thesis presents a novel algorithm for complete coverage of three-dimensional structures to address the problem of autonomous structural inspection using an Unmanned Aerial Vehicle (UAV). The proposed approach uses a technique of cellular decomposition based on Morse decomposition to decompose the 3D target structure into 2D coverable faces that are subsequently connected using a graph-based representation. We then use graph traversal techniques such as the Traveling Salesman Problem (TSP) to generate a flight coverage path through the decomposed faces for a UAV to completely cover the target structure, while reducing the coverage time and distance. To test the validity …

Book Reviews: Raptors Of Mexico And Central America. William S. Clark And N. John Schmitt., Jack Jack Eitniear

The Prairie Naturalist

Whether a raptor is cryptically perched in the shadows or is viewed only as a silhouette soaring in the clouds below the glaring midday sun, raptor identification can be challenging. If you are observing raptors in the North Temperate Zone, several guides (e.g., Clark and Wheeler 2001 Dunne et al.2012) will aid you with such identifications, but few resources exist for visitors south of this zone. So, if you are interested in identifying the 69 species of diurnal raptors found in Mexico and Central America, the recently released Raptors of Mexico and Central America by William S. Clark and N. …

Prairie Falcon Depredation Attempts On A Greater Prairie-Chicken Lek In South-Central Nebraska, Andrew J. Caven, Joshua D. Wiese, William R. Wallauer

The Prairie Naturalist

Little information exists concerning Prairie falcons’ (Falco mexicanus; PRFA) seasonal movements, habitat use, and diet outside of the breeding season; this is especially true in the eastern portion of its wintering and migratory range (Steenhof 1998, Sharpe et al. 2001, Steenhof et al. 2005). Prairie falcons prey on ground squirrels (Spermophilus spp.), prairie dogs (Cynomys spp.), wood rats (Neotoma spp.), and other rodents during the breeding season (Bond 1936, 1942, MacLaren et al. 1988, Steenhof 1998, Steenhof et al. 1999, Johnsgard 2013). They utilize avian prey regionally as well, including western meadowlarks (Sturnella neglecta …
