Cash Is Suprisingly Valuable As A Strategic Asset, Changhyun Kim, Richard A. Bettis

Research Collection Lee Kong Chian School Of Business

Academics, politicians, and journalists are often highly critical of U.S. firms for holding too much cash. Cash holdings are stockpiled free-cash flow and incur substantial opportunity costs from the perspectives of economics. However, behavioral theory highlights the benefits of cash holdings as fungible slack resources facilitating adaptive advantages. We use the countervailing forces embodied in these two theories to hypothesize and test a quadratic functional relationship of returns to cash measured by Tobin's q. We also build and test a related novel hypothesis of scale-dependent returns to cash based on the competitive strategy concept of strategic deterrence. Tests for both …

Passive Takings: The State's Affirmative Duty To Protect Property, Christopher Serkin

Michigan Law Review

The purpose of the Fifth Amendment’s Takings Clause is to protect property owners from the most significant costs of legal transitions. Paradigmatically, a regulatory taking involves a government action that interferes with expectations about the content of property rights. Legal change has therefore always been central to regulatory takings claims. This Article argues that it does not need to be and that governments can violate the Takings Clause by failing to act in the face of a changing world. This argument represents much more than a minor refinement of takings law because recognizing governmental liability for failing to act means …

Study Abroad And Moral Development, Andrew B. Johnson, Danielle R. Hathcock

eJournal of Public Affairs

Why should students study abroad? The standard answer universities give cites three types of benefit: academic, cultural, and professional. We argue that this answer sells the value of study abroad short. Just as important as any of these benefits is the value study abroad has in promoting moral development. Drawing on key ideas of the seminal developmental psychologists Jean Piaget and Lawrence Kohlberg, we make the case that study abroad can facilitate moral development, whether one understands morality in utilitarian, Kantian, or sentimentalist terms. It does so by helping students take the perspective of those who are culturally different, inducing …

The International Classification of Diseases, Tenth Revision has two parts: The International Classification of Diseases, Tenth Revision, Clinical Modification for diagnosis codes and The International Classification of Diseases, Tenth Revision, Procedure Coding System for inpatient procedure codes. Both classification systems incorporate greater specificity, clinical data, and information relevant to ambulatory and to managed-care encounters. With the greater specificity, it is imperative for …

How Copyright Law May Affect Pop Music Without Our Knowing It, Peter K. Yu

Faculty Scholarship

Commissioned for a symposium on copyright law and the creation of music, this article explores five questions about popular music that can be illuminated by greater insights into copyright law and the music business. Why do popular songs usually last for fewer than five minutes? Why are professional songwriters dissatisfied with Pandora and Spotify? Why can we bring European CDs back to the United States? Why can't YouTube videos be created with ASCAP/BMI licenses? Are digital downloads sales or licenses? And as a bonus: Why did the royalty rate for sheet music stay at seven cents per copy?

The Voice Of Low-Income Adolescent Mothers On Infant Feeding, Mildred A. Horodynski, Kristen J. Mills

Journal of Extension

Adolescent mothers' feeding practices impact infant weight gain. Infant obesity, especially in low-income families, is rapidly increasing. The aim of the exploratory study reported here was to identify factors affecting low-income African American and non-Hispanic White adolescent mothers' infant feeding practices and useful learning modalities. Two focus groups were conducted by a trained facilitator using a semi-structured topic guide. Three themes emerged: (1) feeding decisions related to introduction of solid foods; (2) feeding information/advice provided by others; and (3) useful learning strategies. These themes can be used by Extension professionals in designing nutrition education programs for adolescent mothers.

Face Time Is Still Critical To Effective Extension In Commercial Agriculture, Justin Waggoner, Chris Reinhardt

Journal of Extension

Even in the digital era, face-to-face meetings still have impact. Employees and managers must have a similar understanding of the challenges facing their industry. The meeting series described here was designed to allow workers and managers to learn side-by-side. A total of 622 workers and managers representing 75 companies (which have the combined annual capacity to feed approximately 1.8 million cattle, or 9% of the entire U.S. cattle feeding industry) attended seven meetings across western Kansas in which both overarching industry challenges and specific best management practices were communicated. Meeting face-to-face remains an effective way to communicate with commercial agricultural …

Putting A Face On Hunger: A Community-Academic Research Project, Nancy Coffey, Mary K. Canales, Emily Moore, Melissa Gullickson, Brenda Kaczmarski

Journal of Extension

Food insecurity is a growing concern for Eau Claire County residents in Western Wisconsin. A community-academic partnership studied food insecurity through the voices of families struggling to access food and institutions that assist with hunger related problems. Data were collected through focus groups held in urban and rural parts of the county. Participants reported that food insecurity affected all aspects of daily life, increasing stress and reducing coping abilities. Results indicate that when Extension and campus-based staff partner with community groups, they can increase community awareness of and find innovative solutions to pressing community needs, such as food insecurity.

Ethnic And Language Matching: Effects On Hispanics' Treatment Perceptions, Carlos Adrian Ojeda Cedeno

Graduate Theses and Dissertations

Cultural adaptations to mental health treatment have been recommended to improve treatment outcomes in minorities, including Hispanics (Griner & Smith, 2006). One such adaptation includes matching the therapist to the client on culturally salient variables, such as spoken language or ethnic background. Yet, most investigations about the efficacy of matching have been correlational or have not examined language and ethnic match together (Cabassa, 2007). I investigated the effects of both ethnic and language matching on Hispanics' perceptions of psychological treatment. Participants were 100 Hispanic adults (36 men) randomly assigned to one of four conditions. In each condition, participants read a …

Storm Water Damage Risk Assessment Along The South Carolina Heritage Trail, Charles Pellett

All Theses

This study was conducted to better predict and assess damage to high-value small-spatial scale landscapes from storm water. Storm water damage in the form of rill formation across the South Carolina Botanic Gardens (SCBG) Natural Heritage Garden Trail has been modelled as a function of contributing area using D8 and D-infinity flow direction algorithms on a preprocessed LiDAR-derived elevation raster. D8 and D-infinity algorithms were also applied over a set of stochastic Monte Carlo simulations (n=1,000) representing elevation error. The contributing area was calculated using each of the four methods for each 5'x5' cell along the trail. The output was …

Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang

All Theses

Shiga toxin-producing Escherichia coli (STEC), a member of Enterobacteriaceae family, has been recognized as emerging pathogens. Dairy compost is commonly applied to farmland as a soil amendment. Despite the agricultural benefit of manure-based soil amendment, the inadequately treated compost can contribute to fresh produce contamination on the farm. Moreover, the epidemiological results showed that the non-O157 STEC cases have surpassed those of E. coli O157. Therefore, it is critical to evaluate the behavior of non-O157 STEC strains in the dairy manure-based compost. The objectives of this study were to: 1) optimize a culturing method for detecting non-O157 STEC from dairy …

Hand Hygiene Promotion: An Essential Strategy For Preventing Foodborne Disease In Elementary Schools, Zhangqi Wang

All Theses

Student absenteeism is a pervasive problem in the United States, causing a number of educational, economic, and institutional problems. Hand-hygiene interventions have been reported to be a method for reducing illness-associated student absenteeism. As an increasing number of schools offer self-service, including salad bars and bowls of whole fresh fruit, opportunities for the transmission of foodborne pathogens via hands could possibly increase illness-associated student absenteeism. To address this problem, we conducted a two-phase study. First, we conducted a systematic literature review to evaluate peer-reviewed studies (N=24) that reported an association between hand hygiene interventions and illness-associated absenteeism reduction in elementary …

Does Health Insurance Have Influence On Obesity?, Wenyao Zhou

All Theses

Obesity in the United States has been continuing increasing and cited as a major health issue in recent decades. Many researchers have studied its socio-economic cause, but very few studies center on the potential influence that health insurance has on obesity. In our common sense, health insurance reduces the money that we pay for health care and makes many treatments' cost affordable which we may choose to give up originally due to our financial situation. However, everything has two sides. The benefits from insurance also can lead people to change their choices and behaviors. As an insured, people may take …

Scientific Application Acceleration Utilizing Heterogeneous Architectures, Edwin Weill

All Theses

Within the past decade, there have been substantial leaps in computer architectures to exploit the parallelism that is inherently present in many applications. The scientific community has benefited from the emergence of not only multi-core processors, but also other, less traditional architectures including general purpose graphical processing units (GPGPUs), field programmable gate arrays (FPGAs), and Intel's many integrated cores (MICs) architecture (i.e. Xeon Phi). The popularity of the GPGPU has increased rapidly because of their ability to perform massive amounts of parallel computation quickly and at low cost with an ease of programmability. Also, with the addition of high-level programming …

Charitable Donations: An Analysis Of The Differences In Donation Patterns By Income Level, Elizabeth Ficklin

All Theses

This thesis examines the possibility of grouping charitable donors by income level to develop a set of models that can more accurately predict charitable donations. Previous work is inconsistent in predicting charitable donations. This work helps to determine if these inconsistencies are a result of methodological differences between researchers, or if group membership is an important factor in predicting charitable donations as suggested by some researchers. This research only found four variables that were common to all three income groups, frequency of church attendance, family income, age, and years of education. Results show that additional variables can serve as predictors …

Sustenance, Brenton Pafford

All Theses

Utilizing the ceramic process I create objects that facilitate experiences in the domestic space. Developing sculptural elements that evoke memory traces, and in heightening the everyday to an aesthetic, I place value on the overlooked, under-thought items that sustain existence. 'It is the realm of these submerged memory-traces that creative art moves, bringing them into the orbit of everyday life and making them available to the experience of others by formalizing and projecting them onto elements of the familiar world which can receive and transmit them.' - Rawson The objects I created for this exhibition are rooted in memory traces, …

Characterizing Navigational Tools In A Virtual Search Task, Austin Riggs

All Theses

The goal of this thesis is to characterize and empirically compare navigational tools in the context of a virtual inspection task. The framework considers both directional-cue navigational tools (e.g., GPS navigation arrows) and trail navigational tools (e.g.,footprints) in comparison to a control condition. Characterizing the tools allows for documented relationships between specific navigational tool-performance combinations. It is intended that by characterizing and comparing the tools a more advantageous use of navigational tools will emerge to increase the benefit provided to both the users and implementers of virtual environments. The focus of the metrics in the paper were distance traveled, speed …

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu

All Theses

Purpose: Different travel behavior, particularly the choice of commuting modes, will have different impacts on students. On one hand, it has been suggested that active commuting (walking, cycling, and taking transit) will add routine daily exercise. Moreover, health benefits (improved cognitive function and reduced anxiety) from physical activity might increase students' academic performance. Nevertheless, too much physical activity may reduce the time for students to study. Travel time may shorten study time, and study time has been identified as positively contributing to academic performance. Considering that there is limited research examining travel behavior and academic achievement of university students, this …

Inhibition Of Vibrio Cholerae Biofilm Formation By Water-Soluble Cranberry Extracts, Daniel Pederson

All Theses

Vibrio cholerae, a Gram-negative bacterium found in natural aquatic environments, is the causative agent of cholera, a severe diarrheal disease most commonly spread through drinking water. An essential component to this pathogen's success and persistence in the environment is its ability to attach to both biotic and abiotic surfaces via biofilm formation. Biofilms not only aid in surface attachment, but also provide a barrier that protects and enhances survival. Water-soluble extracts from the North American cranberry (Vaccinium macrocarpon) were found to dramatically inhibit V. cholerae biofilm formation at a low concentration of 2mg/ml. This inhibition was not due to acidification …

Jean-Luc Godard And Francois Truffaut: The Influence Of Hollywood, Modernization And Radical Politics On Their Films And Friendship, Caroline Glenn

All Theses

During the late 1950's the French film industry's hard-won financial stability during the Occupation and liberation years had all but disappeared. Combined with the dwindling, unpredictable nature of French audiences, the multi-star, literary adaptation dramas French studios produced were no longer reliable. In response to these dilemmas a transformation took place in French cinema. Known as the nouvelle vague (or French New Wave), the movement was largely, but not completely, a reaction to France's declining film industry. The nation as a whole was undergoing significant change and growth during the 1950s. From the Algerian conflict, the Fourth Republic's collapse and …

Repeated Transradial Catheterization: Feasibility, Efficacy, And Safety, Marinos A Charalambous, Savvas S Constantinides, Michael A Talias, Elpidoforos S Soteriades, Christos P Christou

The Texas Heart Institute Journal

Transradial access is an alternative to the transfemoral approach in coronary interventions. It results in less access-site bleeding, shorter hospital stays, lower costs, and less pain for the patient. However, some authors have suggested that the transradial approach might lead to radial artery occlusion, which precludes repeated same-artery catheterizations. Using data from our center, we evaluated the feasibility, safety, and efficacy of repeated transradial catheterization.

We reviewed the 3,006 transradial catheterizations performed at our center from 2006 through 2009. Patients who had undergone at least one repeated transradial catheterization were identified, their cases monitored through 2012, and their baseline characteristics …

Brachiocephalic Artery Cannulation In Proximal Aortic Surgery That Requires Circulatory Arrest, Mehmet Unal, Oguz Yilmaz, Ilker Akar, Ilker Ince, Cemal Aslan, Fatih Koc, Haluk Kafali

The Texas Heart Institute Journal

The brachiocephalic artery is an alternative cannulation site in the repair of ascending aortic lesions that require circulatory arrest. We evaluate the effectiveness and safety of this technique.

Proximal aortic surgery was performed in 32 patients from 2006 through 2012 via brachiocephalic artery cannulation and circulatory arrest. Twenty-four (75%) of the patients were men. The mean age was 48.69 ± 9.43 years (range, 30–68 yr). Twelve had type I dissection, 2 had type II dissection, and 18 had true aneurysms of the ascending aorta. All operations were performed through a median sternotomy. The arterial cannula was inserted through an 8-mm …

Anticoagulation With Bivalirudin During Deep Hypothermic Circulatory Arrest In A Patient With Heparin-Induced Thrombocytopenia, Agamemnon Pericleous, Mostafa Sadek, Mary Fitzmaurice, Constance Caldwell, Kris Natividad, Konstadinos A Plestis

The Texas Heart Institute Journal

Heparin-induced thrombocytopenia is a well-recognized complication of anticoagulation with heparin. We present the case of a patient with recent heparin-induced thrombocytopenia who subsequently needed surgery on an emergency basis for acute type A aortic dissection. This article reports the successful use of bivalirudin, a direct thrombin inhibitor, as an alternative to heparin throughout cardiopulmonary bypass and deep hypothermic circulatory arrest. We contend that bivalirudin is a safe alternative to heparin when performing surgery for aortic dissection and should be considered as an option for use in patients who present with heparin-induced thrombocytopenia.

Aortic Valve Reconstruction With Use Of Pericardial Leaflets In Adults With Bicuspid Aortic Valve Disease: Early And Midterm Outcomes, Meong Gun Song, Hyun Suk Yang, Jong Bum Choi, Je Kyoun Shin, Hyun Keun Chee, Jun Seok Kim

The Texas Heart Institute Journal

In this study, we retrospectively analyzed the outcomes of adults with bicuspid aortic valve (BAV) disease who underwent aortic valve reconstructive surgery (AVRS), consisting of replacement of the diseased BAV with 2 or 3 pericardial leaflets plus fixation of the sinotubular junction for accurate and constant leaflet coaptation. From December 2007 through April 2013, 135 consecutive patients (mean age, 49.2 ± 13.1 yr; 73.3% men) with symptomatic BAV disease underwent AVRS. Raphe was observed in 84 patients (62.2%), and the remaining 51 patients had pure BAV without raphe. A total of 122 patients (90.4%) underwent 3-leaflet reconstruction, and 13 (9.6%) …
