Information Technology Impacts On Firm Performance: An Extension Of Kohli And Devaraj (2003), Anand Jeyaraj, Rajiv Sabherwal

Management Information Systems Faculty Publications

Despite the importance of investing in information technology, research on business value of information technology (BVIT) shows contradictory results, raising questions about the reasons for divergence. Kohli and Devaraj (2003) provided valuable insights into this issue based on a meta-analysis of 66 BVIT studies. This paper extends Kohli and Devaraj by examining the influences on BVIT through a meta-analysis of 303 studies published between 1990 and 2013. We found that BVIT increases when the study does not consider IT investment, does not use profitability measure of value, and employs primary data sources, fewer IT-related antecedents, and larger sample size. Considerations …

Fire And Flood Expand The Floodplain Shifting Habitat Mosaic Concept, W. J. Kleindl, Mark C. Rains, L. A. Marshall, F. R. Hauer

School of Geosciences Faculty and Staff Publications

The floodplain shifting habitat mosaic concept suggests that habitat patch dynamics are influenced by hydrologic disturbances driven by flood pulses of sufficient power to initiate incipient motion of the substratum and maintain cut-and-fill alluviation of the channel and banks. However, floodplain habitat mosaics are subject to other important landscape-scale disturbance regimes. In the Rocky Mountains of the USA and Canada, fire also affects floodplain habitat patch composition. The floodplain exists at the intersection of disturbance regimes that shape the riverscape and those that shape the landscape. We extended the shifting habitat mosaic concept by examining the effects of multiple disturbance …

Who Will Build The 21st Century?: Addressing Critical Demographic Gaps In The Geosciences, Bradley Cramer, Katherine J. Lewandowski, Arthur Goldstein, Pranoti Asher, Jeffrey G. Ryan, David I. Schofield, Rex Buchanan

School of Geosciences Faculty and Staff Publications

The geoscience workforce in the United States may be facing a critical shortage of trained personnel (Gonzalez and Keane, 2011; NRC, 2013; Mosher et al., 2014; Wilson, 2014a). The National Bureau of Labor Statistics projects a 16% increase in geoscience jobs by 2022. If, as projected, more than half of the present geoscience workforce retires by that time (Wilson, 2014a, 2014b), up to 185,000 new geoscientists will be needed. Graduation rates in U.S. geoscience programs (Wilson, 2014a) are slowly increasing but still lack the capacity to produce such numbers by 2022 (Fig. 1A). The result is a projected shortfall of …

Decoupling Of The Antiferromagnetic And Insulating States In Tb-Doped Sr2Iro4, J. C. Wang, Saicharan Aswartham, Feng Ye, Jsaminka Terzic, H. Zheng, Daniel Haskel, Shalinee Chikara, Yong Choi, P. Schlottmann, Radu Custelcean, Shujuan Yuan, Gang Cao

Physics and Astronomy Faculty Publications

Sr₂IrO₄ is a spin-orbit-coupled insulator with an antiferromagnetic (AFM) transition at T_N=240K. We report results of a comprehensive study of single-crystal Sr₂Ir_1−xTb_xO₄(0≤x≤0.03). This study found that a mere 3% (x=0.03) of tetravalent Tb⁴⁺(4f⁷) substituting for Ir⁴⁺ (rather than Sr²⁺) completely suppresses the long-range collinear AFM transition but retains the insulating state, leading to a phase diagram featuring a decoupling of the magnetic interactions and charge gap. The insulating state at x=0.03 is characterized by …

Evidence For Photoionization-Driven Broad Absorption Line Variability, Tinggui Wang, Chenwei Yang, Huiyuan Wang, Gary J. Ferland

Physics and Astronomy Faculty Publications

We present a qualitative analysis of the variability of quasar broad absorption lines using the large multi-epoch spectroscopic data set of the Sloan Digital Sky Survey Data Release 10. We confirm that variations of absorption lines are highly coordinated among different components of the same ion or the same absorption component of different ions for C ɪᴠ, Si ɪᴠ, and N ᴠ. Furthermore, we show that the equivalent widths (EWs) of the lines decrease or increase statistically when the continuum brightens or dims. This is further supported by the synchronized variations of emission and absorption-line EWs when the well-established intrinsic …

The Inferred Evolution Of The Cold Gas Properties Of Candels Galaxies At 0.5 < Z < 3.0, G. Popping, K. Caputi, S. C. Trager, Rachel S. Somerville, Avishai Dekel, Susan A. Kassin, Dale D. Kocevski, Anton M. Koekemoer, Sandra M. Faber, Henry C. Ferguson, A. Galametz, Norman A. Grogin, Yicheng Guo, Y. Lu, Arjen Van Der Wel, Benjamin J. Weiner

Physics and Astronomy Faculty Publications

We derive the total cold gas, atomic hydrogen, and molecular gas masses of approximately 24 000 galaxies covering four decades in stellar mass at redshifts 0.5 < z < 3.0, taken from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey survey. Our inferences are based on the inversion of a molecular hydrogen based star formation law, coupled with a prescription to separate atomic and molecular gas. We find that: (1) there is an increasing trend between the inferred cold gas (H i and H₂), H i, and H₂ mass and the stellar mass of galaxies down to stellar masses of 10⁸ M_⊙ already in place at z = 3; (2) the molecular fractions of cold gas increase with increasing stellar mass and look-back time; (3) there is hardly any evolution in the mean H i content of galaxies at fixed stellar mass; (4) the cold gas fraction and relative amount of molecular …

Midfield Rf Signal Detector, Dawei Zhang

Electrical Engineering

This project is part of a Master’s thesis which looks at alternative ways to measure blood glucose. The Master’s thesis uses mid-field signals in order to match impedance and therefore lose less power as they travel through flesh. The goal of this senior project is to build a receiver for those signals and give accurate RSSI (received signal strength indicator) measurements. Mid-fields were originally explored by Stanford professor Dr. Ada Poon [3] who used the signaling technique to recharge the batteries of deeply implanted devices. Devices implanted near the surface of the skin were able to have their batteries recharged …

Influence Of Benagene Supplementation In Conjunction With High Intensity Cycling Exercise, Wilson P. Simmons

Honors Theses

High intensity aerobic performance is determined by the body’s maximal ability to match lactate production and clearance rates, defined as the lactate threshold (LaTh). Intensities performed above the LaTh result in accumulation of lactate causing fatigue. In a double-blind experiment, using trained cyclists and triathletes, we investigated skeletal muscle adaptations that occurred following 28-days of Benagene supplementation (oxaloacetate). The testing protocol consisted of an initial cycle test (T1) to measure VO₂max, LaTh, respiratory exchange ratio (RER), power output (PO) and heart rate (HR). Testing began after a 15-min warm-up at 75W, beginning at 100W, increasing 30W each 3-min …

Democratizing Dionysus: The Origins Controversy And The Dual Evolution Of Tragedy And Civism, Belen Plaza-Gainza

Honors Theses

Finding the origins of tragedy has been a fascinating subject since late antiquity, and it continues to be a source of academic debate. The controversy I have examined is from the early years of our twenty-first century, and has questioned the testimony of Aristotle, opening the debate once again. The evidence continues to prove that tragedy’s origins were religious, and even though there is no hard evidence to prove that it evolved from Dionysiac ritual, there is no hard evidence to disprove this theory either.

I have taken this opportunity to examine the origins of tragedy from its evolution, which …

Young And Unemployed: A Multivariable Analysis Of Youth Unemployment In Jordan, Morgan E. Mabry

Honors Theses

The level of youth unemployment in the Middle East is higher than any other region in the world. The detrimental effects of early unemployment can be broad and long lasting. This paper discusses some of the factors of youth unemployment in the Middle East, such as poor education systems and underdeveloped labor markets; and the social effects such as delayed marriages and political unrest. It then goes on to analyze the School-to-Work Transition Survey (SWTS) to understand the impact of age, sex, individual education, and parental education on the transition from school to work. The results indicated that sex and …

Characterization Of Embryonic Stem Cell-Differentiated Cells As Mesenchymal Stem Cells, Rachael N. Kuehn

Honors Theses

Embryonic stem cells (ESCs), due to their ability to differentiate into different cell types while still maintaining a high proliferation capacity, have been considered as a potential cell source in regenerative medicine. However, current ESC differentiation methods are low yielding and create heterogeneous cell populations. If transplanted in the human body, differentiated ESCs could be rejected by the immune system, form tumors, or may not function normally within the human body. On the other hand, mesenchymal stem cells (MSCs), a type of adult stem cell typically derived from bone marrow, have proved to be excellent candidates in clinical applications due …

An Analysis Of The Relationship Between Study Styles And Demographics Across Multiple Accounting Class Levels, Savannah B. Hooper

Honors Theses

Approaches to learning are elemental to a student’s learning outcomes. Prior research indicates that accounting students with a deep learning approach have a more successful student learning outcome than do accounting students with a surface learning approach. Accounting accreditation and regulatory agencies have recommended that coursework be directed towards more critical thinking and real-life preparation of students. These characteristics are indicative of the deep learning approach. After ascertaining the learning approach adopted by introductory, intermediate, and advance accounting students at a public university with a main and satellite campus, this paper reports on demographic characteristics that may impact a student’s …

Currently technological and regulatory changes are creating challenges for community banks. To combat these issues many community banks are increasing their merger and acquisition activity to avoid closing. This objective of this paper is to discuss the reasons community banks are so important to our economy and to define the hardships they are currently facing. It is also important to identify the next steps we should take to ensure the stability of …

¿Dónde Están Todas Las Mujeres?: The Impact Of Female Labor Force Participation On Female Political Representation In Latin America, Murakami A. Carpenter

Honors Theses

Do higher levels of female labor force participation increase female political representation? Over the past 40 years, the involvement of Latina women in the labor force and the number of female legislators in Latin America has been steadily increasing. To determine if there is a correlation between these two variables, this research builds on the socio-economic status model created by Brady, Verba and Schlozman (1995). Using both a bivariate and a multivariate model, I test for a correlation between the number of women working and the number of elected female legislators in 24 Latin American countries. Contrary to expectations, I …

Exploration Of The United States’ Cultural Legacy In Panama Through Analysis Of American Foreign Policy And Public Opinion, Katherine A. Boss

Honors Theses

The study of a culture is nearly too difficult to accomplish academically, therefore the consilience of data, personal experience, and public opinion offers the most comprehensive approach. The Panama Canal has just celebrated its centennial and remains to this day one of the most important geopolitical and global economic hubs in the world. Nearly every country that participates in maritime trade utilizes the canal. Panama has ambitious plans for the canal’s future, as it nears completion of a multibillion dollar expansion project; however predicting how Panama handles this growth and new responsibility as a major world power is directly related …

Biochar From Pyrolysis Of Biosolids For Nutrient Adsorption And Turfgrass Cultivation, Daniel Elliott Carey, Patrick J. Mcnamara, Daniel Zitomer

Civil and Environmental Engineering Faculty Research and Publications

At water resource recovery facilities, nutrient removal is often required and energy recovery is an ever-increasing goal. Pyrolysis may be a sustainable process for handling wastewater biosolids because energy can be recovered in the py-gas and py-oil. Additionally, the biochar produced has value as a soil conditioner. The objective of this work was to determine if biochar could be used to adsorb ammonia from biosolids filtrate and subsequently be applied as a soil conditioner to improve grass growth. The maximum carrying capacity of base modified biochar for NH₃−N was 5.3 mg/g. Biochar containing adsorbed ammonium and potassium was …

Testing The Heckscher-Ohlin-Vanek Theory With A Natural Experiment, Assaf Zimring

Upjohn Institute Working Papers

This paper uses the historical episode of the near-elimination of commuting from the West Bank into Israel, which caused a large and rapid expansion of the local labor force in the West Bank, to test the predictions of the Heckscher-Ohlin-Vanek (HOV) mode of trade. I use variation between districts in the West Bank to test these predictions, and find strong support for them: Wage changes were not correlated with the size of the shock to the district labor force (Factor Price Insensitivity); Districts that received larger influx of returning commuters shifted production more towards labor intensive industries (Rybczynski effect); And …

Wide bandgap semiconductor materials such as gallium nitride (GaN) and silicon carbide have grown in popularity as a substrate for power devices for high temperature and high voltage applications over the last two decades. Recent research has been focused on the design of integrated circuits for protection and control in these wide bandgap materials. The ICs developed in SiC and GaN can not only complement the power devices in high voltage and high frequency applications, but can also be used for standalone high temperature control and data acquisition circuitry.

This dissertation work aims to explore the possibilities in high temperature …

The Mass-Pitch Angle Relation For Three High Redshift Active Galaxies Selected From The Goods Field, John Adam Hughes

Graduate Theses and Dissertations

As we continue to investigate and ponder the heavens, we have come to realize the presence of highly energetic gravitational wells at the center of all galaxies. These supermassive black holes at a galaxies nucleus formed in the company of the other features making up the galaxy, particularly spiral arms. With nearby galaxies showing a relationship between the spiral arm pitch angle and that central mass, here we push that relationship out to distances of redshift one. With three galaxies at this distance we find that they also hold to the same relationship of tighter spiral arms corresponding to more …

Thermodynamic Modeling Of Aqueous Geochemistry Of Chlorine Salts: Application To Stability And Habitability Of Liquid Brines On Mars, Amira Elsenousy

Graduate Theses and Dissertations

The WCL (Wet Chemistry Lab) instrument on board the Mars’s Phoenix Lander has identified the soluble ionic composition of the soil at the landing site. Two important ions were detected at the landing site; perchlorates (ClO4-) with a concentration of ~ 2.4 wt% and chlorides (Cl-) with a concentration of 0.54 wt%. Between chloride and perchlorate ions three other oxidized ions exist and called chlorine ions: hypochlorite ClO - (ox. state +1), chlorite ClO2- (ox. state +3) and chlorate ClO3- (ox. state +5). These oxidized ions might be existed as intermediate species on the surface of Mars but remained undetected. …

Predictors Of Texas Police Chiefs’ Satisfaction With Police-Prosecutor Relationships, Brenda I. Rowe

Criminology and Criminal Justice Faculty Publications (Archived)

Although strain in police-prosecutor relationships may be built into the criminal justice system’s checks and balances, the administration of criminal justice can benefit from the adoption of practices which improve these working relationships. A first step towards the adoption of such practices can be taken by first adding to the knowledge base regarding this understudied topic. Using a survey of a state-wide sample of Texas police chiefs, this exploratory study identifies which aspects of police-prosecutor interaction styles are predictors of police chiefs’ satisfaction with police-prosecutor relationships. Results indicate that perceived level of police input in prosecutors’ plea bargain and charging …
