On The Governance Of Innovation: Institutional Ownership Vs. Stock Price, Huong Thi Thu Le Jan 2014

On The Governance Of Innovation: Institutional Ownership Vs. Stock Price, Huong Thi Thu Le

LSU Doctoral Dissertations

Firms can change their outstanding shares to manage their stock price levels. Those with lower stock prices tend to attract more speculative trading, which causes higher price volatility and may force their managers to excessively focus on short-term earnings at the expense of R&D and other long-term projects. Thus, I hypothesize that keeping high stock price levels allows firms to (i) limit speculative traders’ influences on stock prices and thus mitigate investor short-termism, and (ii) enhance R&D productivity. Indeed, I find that high-priced firms are less likely to cut R&D to reverse an earnings decline, less likely to fire their …

Climate Extremes In The Southeast United States : Variability, Spatial Classification, And Related Planning, Emily J. Powell Jan 2014

Climate Extremes In The Southeast United States : Variability, Spatial Classification, And Related Planning, Emily J. Powell

LSU Doctoral Dissertations

Spatial and temporal trends in temperature and precipitation extremes were investigated for the Southeast United States for the period 1948 to 2012 using 27 extreme indices developed by Working Groups headed by the World Meteorological Organization. Results show region-wide warming in extreme minimum temperatures and cooling in extreme maximum temperatures. As a result, diurnal temperature ranges are decreasing for most stations. The intensity and magnitude of extreme precipitation events appear to be rising overall, though eastern sites are experiencing increasing dryness in some indices. Seasonal trends suggest that warming in minimum temperatures is most pronounced in summer and least pronounced …

Can You Hear Me Now: A Cross-National Analysis Of Media, New Icts, Press Freedoms And Sociopolitical Instability, Conflict, And Democracy., Britt Christensen Jan 2014

Can You Hear Me Now: A Cross-National Analysis Of Media, New Icts, Press Freedoms And Sociopolitical Instability, Conflict, And Democracy., Britt Christensen

LSU Doctoral Dissertations

Using cross-national panel data, I investigated relationships among sociopolitical instability, major intrastate conflicts, democracy levels, and media and new information and communication technologies (ICTs) penetration rates and press freedoms. I conducted similar analyses regarding all non-democracies, looking at various types of political instability and media/ICT penetration rates. The results of this research add to democratic, freedom of expression, and political communication theories. These findings bring empirical evidence to help illuminate many of the popular debates surrounding the impact of new ICTs and freedom of expression on popular dissident activities. My results suggested that countries with higher rates of Internet and …

Leader Benefits: Exploring How Leaders Benefit From Lmx, Jeffrey Muldoon Jan 2014

Leader Benefits: Exploring How Leaders Benefit From Lmx, Jeffrey Muldoon

LSU Doctoral Dissertations

Leader Member Exchange (LMX) theory has emerged as one of the most prominent leadership theories over the last thirty years. Scholars found that subordinates with elevated levels of LMX experience higher degrees of job satisfaction and work motivation, experience lower levels of burnout and turnover intentions, and demonstrate stronger contextual and focal job performance. Yet the work outcomes for supervisors have not been heavily researched. Scholars assume, but have not demonstrated, that supervisors gain cognitive and affective benefits beyond job performance from their relationships with subordinates. These benefits are crucial because they are common to social exchange and differentiate supervisor/subordinate …

Evaluation Of Economic Injury Levels And Chemical Control Recommendations For Rice Stink Bug (Oebalus Pugnax) In Louisiana, Bryce Blackman Jan 2014

Evaluation Of Economic Injury Levels And Chemical Control Recommendations For Rice Stink Bug (Oebalus Pugnax) In Louisiana, Bryce Blackman

LSU Doctoral Dissertations

Experiments were carried out from 2010 to 2013 to investigate multiple aspects of rice stink bug (RSB) integrated pest management (IPM): insecticide recommendations, sampling efficiency, treatment thresholds, farmer practices, and improved educational tools. The first objective of this research was to compare the efficacies of currently used insecticides with that of a new product from the neonicotinoid class of insecticides. Experiments were carried out in the laboratory, small field plots, and commercial fields across Louisiana. Results from efficacy trials showed that the neonicotinoid was comparable to pyrethroid products used most by rice producers in Louisiana. Conversely, in separate experiments the …

Has The Fasb And Iasb's Shift Toward An Asset/Liability View Enhanced The Predictive Usefulness Of Roe?, Regina Cavalier Rosa Jan 2014

Has The Fasb And Iasb's Shift Toward An Asset/Liability View Enhanced The Predictive Usefulness Of Roe?, Regina Cavalier Rosa

LSU Doctoral Dissertations

Over the past several decades, accounting standard setters have been gradually shifting financial reporting toward an asset/liability view, by rewriting the underlying conceptual framework and issuing accounting standards that reflect this view. The asset/liability view enhances comparability of a firm’s investment base to that of its peers, and thus enhances the comparability of a firm’s return of equity (ROE). This, in turn, increases the transparency with which firm-specific performance differs from its peers. Greater transparency would be expected to improve predictive usefulness, but would also place greater pressure on a firm to meet the performance of its peers. In the …

Subjugated Territory: The New Afrikan Independence Movement And The Space Of Black Power, Paul Karolczyk Jan 2014

Subjugated Territory: The New Afrikan Independence Movement And The Space Of Black Power, Paul Karolczyk

LSU Doctoral Dissertations

In this dissertation, I study the black revolutionary nationalist geography of the New Afrikan Independence Movement (NAIM) and the anti-racist space of Black Power. I adapt social theorist Henri Lefebvre’s concept of representational space to show how New Afrikan revolutionary nationalism intersects with space, place, and scalar politics in a representational space of black radicalism that confounds dominant notions of race, cultural identity, and national belonging in the United States. NAIM originated in 1968 when several-hundred black nationalist delegates met at the National Black Government conference in Detroit to create the Provisional Government of the Republic of New Afrika. New …

Teacher Matters: Teacher Normative Influence And Student Persistence In College, Jonathan Paul Denham Jan 2014

Teacher Matters: Teacher Normative Influence And Student Persistence In College, Jonathan Paul Denham

LSU Doctoral Dissertations

This dissertation extends the work on teacher immediacy (TI) and student persistence by using the Theory of Planned Behavior (TPB) (Ajzen, 1985) to account for variability in college student persistence. Students provided perceptions of their teachers’ immediacy behaviors using modified versions of Gorham’s (1988) TI scale. Instruction prompts of the TI scale were manipulated to create four conditions. The results from Study 1 demonstrate that TI scale prompt language has an effect on the ways participants assess their teacher’s immediacy behaviors. The results from Study 2 show that student perceptions of their teacher’s immediacy behaviors change over the course of …

Reducing Juvenile Justice Involvement Through A Childhood Truancy Intervention, Bret James Blackmon Jan 2014

Reducing Juvenile Justice Involvement Through A Childhood Truancy Intervention, Bret James Blackmon

LSU Doctoral Dissertations

This study employed a mixed methods design to evaluate an elementary school truancy intervention in terms of reducing rates of juvenile delinquency over six years. Few (n = 11) participants became involved in the formal justice system, so the intervention’s effectiveness was measured by re-referrals for continued truancy. The regression discontinuity design was used to compare the intervention group to the comparison group. The intervention group received intensive case management and the comparison group received a warning letter. A regression discontinuity design using multivariate logistic regression indicated that the intervention did not reduce the likelihood of subsequent re-referrals, and the …

Lopsided, Scarred, And Squint-Eyed: Ugly Women In The Work Of Southern Women Writers, Monica C. Miller Jan 2014

Lopsided, Scarred, And Squint-Eyed: Ugly Women In The Work Of Southern Women Writers, Monica C. Miller

LSU Doctoral Dissertations

The ubiquity of ugly female characters in the work of southern women calls into question what W. J. Cash termed “gyneolatry,” the worship of the beautiful white woman upon which so much of southern ideology has been based. If the South functions as an internal other for the nation, then examining this fiction’s multiplicity of ugly women illuminates the ways in which women defy not only the norms of southern gender but also those of the larger American culture, in which the southern woman often acts as a representation of the South in general. By considering ugliness as a category …

Lightweight Data Compression In Wireless Sensor Networks Using Huffman Coding, Henry P. Medeiros, Marcos C. Maciel, Richard D. Souza, Marcelo E. Pellenz Jan 2014

Lightweight Data Compression In Wireless Sensor Networks Using Huffman Coding, Henry P. Medeiros, Marcos C. Maciel, Richard D. Souza, Marcelo E. Pellenz

Electrical and Computer Engineering Faculty Research and Publications

This paper presents a lightweight data compression method for wireless sensor networks monitoring environmental parameters with low resolution sensors. Instead of attempting to devise novel ad hoc algorithms, we show that, given general knowledge of the parameters that must be monitored, it is possible to efficiently employ conventional Huffman coding to represent the same parameter when measured at different locations and time periods. When the data collected by the sensor nodes consists of integer measurements, the Huffman dictionary computed using statistics inferred from public datasets often approaches the entropy of the data. Results using temperature and relative humidity measurements show …

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah Jan 2014

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah

Geography

Sustainability science has grown as a field of inquiry, but has said little about the role of large-scale private sector actors in socio-ecological systems change. However, the shaping of global trends and transitions depends greatly on the private sector and its development impact. Market-based and command-and-control policy instruments have, along with corporate citizenship, been the predominant means for bringing sustainable development priorities into private sector decision-making. This research identifies conflict as a further means through which environmental and social risks are translated into business costs and decision making. Through in-depth interviews with finance, legal, and sustainability professionals in the extractive …

Albedo-Induced Radiative Forcing From Mountain Pine Beetle Outbreaks In Forests, South-Central Rocky Mountains: Magnitude, Persistence, And Relation To Outbreak Severity, M. Vanderhoof, C. A. Williams, Y. Shuai, D. Jarvis, Dominik Kulakowski, J. Masek Jan 2014

Albedo-Induced Radiative Forcing From Mountain Pine Beetle Outbreaks In Forests, South-Central Rocky Mountains: Magnitude, Persistence, And Relation To Outbreak Severity, M. Vanderhoof, C. A. Williams, Y. Shuai, D. Jarvis, Dominik Kulakowski, J. Masek

Geography

Mountain pine beetle (MPB) outbreaks in North America are widespread and have potentially persistent impacts on forest albedo and associated radiative forcing. This study utilized multiple data sets, both current and historical, within lodgepole pine stands in the south-central Rocky Mountains to quantify the full radiative forcing impact of outbreak events for decades after outbreak (0-60 yr) and the role of outbreak severity in determining that impact. Change in annual albedo and radiative forcing peaked at 14-20 yr post-outbreak (0.06 ± 0.006 and-0.8 ± 0.1 W m-2, respectively) and recovered to pre-outbreak levels by 30-40 yr post-outbreak. Change in albedo …

Does Subtype Matter?: Comparing The Effects Of A Self-Monitoring Intervention On Adhd-C And Adhd-I, Caleb James Corwin Jan 2014

Does Subtype Matter?: Comparing The Effects Of A Self-Monitoring Intervention On Adhd-C And Adhd-I, Caleb James Corwin

LSU Doctoral Dissertations

Recently Attention-Deficit/Hyperactivity Disorder (ADHD) research has been confronted with questions regarding the subtype distinctions. Millich, Ballantine, and Lyman (2001) have claimed that ADHD – Combined Type (ADHD-C) and ADHD – Predominantly Inattentive Type (ADHD-I) are “distinct and separate disorders.” As important as this distinction is diagnostically, it is, possibly equally important with regards to treatment. Multiple pharmacological studies have compared the responsiveness of ADHD-C and ADHD-I to stimulant medications, yet the results are often conflicting (e.g. Grizenko, Paci, & Joober, 2010; Solanto et al., 2009; Stein et al., 2003). To date, only one study has compared ADHD subtypes with respect …

Audio-Based Visualization Of Expressive Body Movements In Music Performance: An Evaluation Of Methodology In Three Electroacoustic Compositions, Yeamin Oh Jan 2014

Audio-Based Visualization Of Expressive Body Movements In Music Performance: An Evaluation Of Methodology In Three Electroacoustic Compositions, Yeamin Oh

LSU Doctoral Dissertations

An increase in collaboration amongst visual artists, performance artists, musicians, and programmers has given rise to the exploration of multimedia performance arts. A methodology for audio-based visualization has been created that integrates the information of sound with the visualization of physical expressions, with the goal of magnifying the expressiveness of the performance. The emphasis is placed on exalting the music by using the audio to affect and enhance the video processing, while the video does not affect the audio at all. In this sense the music is considered to be autonomous of the video. The audio-based visualization can provide the …

Programming Generalization : The Use Of Sufficient Exemplars Within A Discrete Trial Training Early Intervention Program For Children With Autism Spectrum Disorder, Carolyn Barahona Jan 2014

Programming Generalization : The Use Of Sufficient Exemplars Within A Discrete Trial Training Early Intervention Program For Children With Autism Spectrum Disorder, Carolyn Barahona

LSU Doctoral Dissertations

Discrete Trial Training (DTT), a skill acquisition paradigm using Applied Behavioral Analysis (ABA) principles, is an empirically validated early intervention method for children with ASD. However, one disadvantage of this treatment is its highly structured method that hinders generalization. Since generalization is essential for independence and overall functioning in children with ASD, programming for generalized behavior change is an important treatment component. Training sufficient exemplars is one generalization programming technique that has led to the transfer of skills across several stimulus contexts. Very few scientific investigations have evaluated the use of sufficient exemplars within a DTT format. Experiment 1 evaluated …

A Data-Driven Storm Surge Analysis For The U.S. Gulf Coast, Harold Francis Needham Jan 2014

A Data-Driven Storm Surge Analysis For The U.S. Gulf Coast, Harold Francis Needham

LSU Doctoral Dissertations

This dissertation provides the first empirical storm surge analysis for the U.S. Gulf Coast. Data are provided by SURGEDAT, a comprehensive storm surge database. A global storm surge literature review provided more than 700 observations in six ocean basins. The most severe storm surges have occurred in the Bay of Bengal, and the most frequent low-magnitude surges have occurred in East Asia. The U.S. Gulf Coast experiences the second highest frequency of low- and high- magnitude storm surges. Two Gulf Coast studies revealed that storm surge heights correlate better with pre-landfall tropical cyclone conditions, such as maximum wind speed and …

Numerical Experiments Of Hurricane Impact On Vertical Mixing And De-Stratification Of The Louisiana Shelf Waters, Mohammadnabi Allahdadi Jan 2014

Numerical Experiments Of Hurricane Impact On Vertical Mixing And De-Stratification Of The Louisiana Shelf Waters, Mohammadnabi Allahdadi

LSU Doctoral Dissertations

The numerical model FVCOM (Finite Volume Community Ocean Model) was applied to study the effects of Hurricane Katrina on the vertical mixing over the Louisiana shelf and the process of post-storm re-stratification. Wind field from Hurricane Katrina was generated using a single vortex analytical model and was evaluated using available wind measurements over the shelf. Simulations of shelf circulation under Hurricane Katrina were done through several numerical tests to find the best approach for treating vertical eddy viscosity. Model results for the shelf during Katrina demonstrated opposite currents between surface and bottom for most of the shelf area. Results also …

Southern Sapphisms: Sexuality And Sociality In Literary Productions, 1974-1997, Jaime Cantrell Jan 2014

Southern Sapphisms: Sexuality And Sociality In Literary Productions, 1974-1997, Jaime Cantrell

LSU Doctoral Dissertations

Southern Sapphisms: Sexuality and Sociality in Literary Productions, 1974-1997, considers how queer and feminist theories illuminate and complicate the intersections between canonical and obscure, queer and normative, and regional and national narratives in southern literary representations produced during a crucial but understudied period in the historical politicization of sexuality. The advent of New Southern Studies—and its nascent emphasis on sexuality as an organizing principle of social relations—has focused almost exclusively on midcentury texts from the Southern Renascence, largely neglecting post-1970 queer literatures. At the same time, despite these developments in southern studies, most scholarship in women’s and feminist studies continue …

Accountable Actors: Politics And Poetic Imagination In Huxley, Lewis, And Orwell, Sarah Beth Vosburg Jan 2014

Accountable Actors: Politics And Poetic Imagination In Huxley, Lewis, And Orwell, Sarah Beth Vosburg

LSU Doctoral Dissertations

What does it mean, and what does it take, to practice personal responsibility in the face of political oppression? In this dissertation, I trace the essential themes of responsibility through a critical analysis of three stories: Aldous Huxley’s Brave New World, C. S. Lewis’s That Hideous Strength, and George Orwell’s Nineteen Eighty-Four. No comparative study of these important works of twentieth-century political literature exists. Yet, each of these stories merits the attention of students of character and politics because all three unforgettably portray men who strive to live meaningful lives against the contrived meaning imposed on them by those in …

An Examination Of The Impact Of Postsecondary Transition Program Models On College Self-Efficacy Beliefs Of First-Generation College Students, Shaneá Morrison Nelson Jan 2014

An Examination Of The Impact Of Postsecondary Transition Program Models On College Self-Efficacy Beliefs Of First-Generation College Students, Shaneá Morrison Nelson

LSU Doctoral Dissertations

The primary purpose of this study was to examine the impact of postsecondary transition programs on the college self-efficacy beliefs of first-generation college students. Postsecondary transition programs were developed to address the challenges that all first-time freshmen face, including all first-generation students. While there are a number of postsecondary transition program models, the three models examined in this study were Developmental Academic, Residential Colleges, and First Year Intervention programs. Although there is a great deal of evaluative research regarding how postsecondary transition programs impact students’ academic performance, there is a lack of research on how these programs impact students internal …

Supporting Diverse Online Learners, Charlotte Nirmalani Gunawardena Jan 2014

Supporting Diverse Online Learners, Charlotte Nirmalani Gunawardena

University Libraries & Learning Sciences Faculty and Staff Publications

Learner support is the critical link in online education. A learner support system is comprised of human and non-human resources that contribute to the learning process of an online course and should be designed as an integral part of the course. For example, if the online course requires students to access library resources to complete a research paper, then, easy access to library resources must be provided as part of the learner support system for that course. Learner support for online learners will differ based on the context, learner characteristics such as needs, expectations, prior learning experiences, etc., and the …

The Role Of Organisational Culture In The Merger Of English Local Authorities Into A Single Unitary Authority, Colin Cresswell, Jonathan Moizer, Jonathan Lean Jan 2014

The Role Of Organisational Culture In The Merger Of English Local Authorities Into A Single Unitary Authority, Colin Cresswell, Jonathan Moizer, Jonathan Lean

Plymouth Business School

Cornwall Council is a new ‘unitary’ local authority which was created following the merger of six district councils and one county council on 1 April 2009. A questionnaire survey based on specific ‘dimensions’ of organisational culture was circulated to staff prior to the merger date. Overall, the results indicated a generally congruent culture characterised by a strong team spirit and commitment to the workplace. A number of differences were observed between the cultural orientations of the seven councils, but there was only weak evidence of differences between tiers of management or professional groupings. The study suggests that the new organisation …

The Woman Question In Post-Socialist Legal Education, Isabel Marcus Jan 2014

The Woman Question In Post-Socialist Legal Education, Isabel Marcus

Journal Articles

Sex equality—a significant contribution to the international human rights canon—was one of the legitimating principles of socialist states in Eastern Europe and, at least formally, of their post-socialist democratic successors. Why then has the subject been ignored or deeply marginalized in post-socialist legal education? Using socio-legal analysis to establish a legitimation or delegitimation dynamic regarding law in theory and practice in both eras, the author provides answers to this question and suggests various options for reforming post-socialist legal education to provide adequate training in the subject of women’s rights consistent with states’ international and regional human rights obligations.

A Foot In Both Camps: The Influence Of Role Identity Centrality Of Professional Service Entrepreneurs On Entrepreneurial Orientation And Firm Performance, Steven Anthony Stewart Jan 2014

A Foot In Both Camps: The Influence Of Role Identity Centrality Of Professional Service Entrepreneurs On Entrepreneurial Orientation And Firm Performance, Steven Anthony Stewart

Electronic Theses and Dissertations 2010 - 2019

Professional service entrepreneurs (PSEs) paradoxically practice their profession in highly institutionalized contexts which require significant socialization, while at the same time enacting their role as an entrepreneur. Some activities consistent with entrepreneurship may be unnecessary for—and possibly even contradictory with— activities consistent with professional roles. In this dissertation, I addressed the questions of how two highly central role identities (professional and entrepreneurial) related to entrepreneurial orientation (EO) in professional service practices, and how EO influences performance in the context of professional practices. Using a sample of 139 physicians, I examined the relationships between the role identity centrality of two primary …
