LSU Doctoral Dissertations

This study applied a holistic method of healthcare program assessment, known as systems approach, to evaluate the efficacy of the East Baton Rouge Parish (EBRP) EMS Community-integrated Health Program (CIHP). The author developed assessment metrics following the Quadruple Aim Framework: IHI (Institute for Healthcare Improvement) Triple Aim + Provider Experience.

Results showed that the CP program in this study delivers high ratings on patient experience and provided a 51% return on investment (ROI) through reduced emergency service utilization, ED visits and inpatient hospital admissions. However, findings did not demonstrate meaningful improvement in patients’ health-related quality of life (HRQoL) and self-efficacy …


Accelerated Capital Allowances: An Overview, Bernard Doherty, James Mc Mahon, William Coffey, Ger Nagle, Kevin Delaney Sep 2019

Accelerated Capital Allowances: An Overview, Bernard Doherty, James Mc Mahon, William Coffey, Ger Nagle, Kevin Delaney

Articles

ACA is based on the existing capital allowances tax structure or wear and tear allowance, for plants and machinery. Claiming the ACA is carried out the same way as for the standard capital allowances.

Organisations who invest in eligible energy-efficient capital equipment can deduct the full cost of the equipment from their profits in the year of purchase. This reduces the taxable profit in year one by the full cost of the equipment.


Academic Skill Learning And The Problem Of Complexity I: Creational Purposeful Integrated Capability At Skill (Cpics), Martin F. Gardiner Sep 2019

Academic Skill Learning And The Problem Of Complexity I: Creational Purposeful Integrated Capability At Skill (Cpics), Martin F. Gardiner

Northeast Journal of Complex Systems (NEJCS)

Physical and mental skills are intended to achieve success at acting purposefully. As capability at any skill increases, the need to adjust details of application to complexity of context and goals will increase as well. It will become more and more important to prepare mentally for what I now term Creational Purposeful Integrated Capability at Skill (CPICS). This paper develops what I mean by CPICS. Theory concerning Complex Dynamical Systems (CDS) such as the brain and other evidence points to the likelihood that the mental operations by which our brain produces any kind of skillful behavior cannot remain constant, …


Being In Uncertainties: An Inquiry-Based Model Leveraging Complexity In Teaching-Learning, Diane Rosen Sep 2019

Being In Uncertainties: An Inquiry-Based Model Leveraging Complexity In Teaching-Learning, Diane Rosen

Northeast Journal of Complex Systems (NEJCS)

Education is traditionally structured as a closed system, privileging result-driven methods that offer control and predictability. In recent decades this reductionist approach has been effectively challenged by interdisciplinary work in complex systems theory, revealing myriad levels of orderly disorder that make either-or, linear instruction an inadequate norm. Narrowing the broad implications of a complexity lens on education, this paper focuses on generative uncertainty in teaching-learning, a paradoxical state of epistemological and creative growth described by English poet John Keats as "the negative capability of being in uncertainties, mysteries, doubts." Opportunities to advance this potentiating capacity are especially abundant in constructivist …


Creativity As An Emergent Property Of Complex Educational System, Ceire Monahan, Mika Munakata, Ashwin Vaidya Sep 2019

Creativity As An Emergent Property Of Complex Educational System, Ceire Monahan, Mika Munakata, Ashwin Vaidya

Northeast Journal of Complex Systems (NEJCS)

The importance of creativity in education has been discussed often in the literature. While there remains no agreed-upon definition of creativity, the psychological literature points to traits of a creative person. These include the ability to think outside the box, make connections between seemingly disparate ideas, and question norms. The literature provides several examples of classroom experiments to help foster creativity in the classroom. In science and mathematics, we can start by getting students to recognize mathematics and the sciences as being creative endeavors. While these attempts are noteworthy, they are not necessarily aligned with instructional practices. In this article, …


Rethinking Educational Reforms Through A Complex Dynamical Systems Approach: Preliminary Report From An Empirical Research, Eugenia Tsiouplis, Dimitrios Stamovlasis Sep 2019

Rethinking Educational Reforms Through A Complex Dynamical Systems Approach: Preliminary Report From An Empirical Research, Eugenia Tsiouplis, Dimitrios Stamovlasis

Northeast Journal of Complex Systems (NEJCS)

Literature on educational reforms is rich of cases where changes have been attempted, without however to attain success. Likewise the Greek education system had experienced a lot of reforms, most of which have failed to make the intended changes and they attenuated shortly after their implementation or they ceased at the stage of legislative planning. On the other hand, the traditional research have failed to develop a coherent theoretical perspective and provide satisfactory interpretations of the perpetually unsuccessful reforms. This paper is part of wider project which attempts to address the above issue following the Complex Dynamical Systems (CDS) perspective, …

Fractality And Power Law Distributions: Shifting Perspectives In Educational Research, Matthijs Koopmans Sep 2019

Fractality And Power Law Distributions: Shifting Perspectives In Educational Research, Matthijs Koopmans

Northeast Journal of Complex Systems (NEJCS)

The dynamical character of education and the complexity of its constituent relationships have long been recognized, but the full appreciation of the implications of these insights for educational research is recent. Most educational research to this day tends to focus on outcomes rather than process, and rely on conventional cross-sectional designs and statistical inference methods that do not capture this complexity. This presentation focuses on two related aspects not well accommodated by conventional models, namely fractality (self-similarity, scale invariance) and power law distributions (an inverse relationship between frequency of occurrence and strength of response). Examples are presented for both phenomena …


Competitive Strategies In Small And Medium Sized Enterprises (Sme's): A Cross- Case Analysis Of Irish Construction Professional Service Firms, Oluwasegun O. Seriki, Roisin Murphy Sep 2019

Competitive Strategies In Small And Medium Sized Enterprises (Sme's): A Cross- Case Analysis Of Irish Construction Professional Service Firms, Oluwasegun O. Seriki, Roisin Murphy

Conference papers

Strategy formulation aims to attain strategic fit between an organisation and its business environment in pursuit of competitive advantage. Although competitive strategy research is long established within industries such as manufacturing, financial services and IT, strategy within construction is still under-investigated by comparison. For construction professional service firms (CPSFs), the dearth of academic inquiry is even more apparent, partly due to the intangible nature of their service offerings, highly customised nature of their services and reliance on intellectual capital. The Irish construction sector is experiencing stable growth since following a prolonged recession, thus understanding the strategy process within professional service …


A Study Of Onboarding And Turnover Mediating Variables In U.S. Air Force Officers, Brett S. Bowers Sep 2019

A Study Of Onboarding And Turnover Mediating Variables In U.S. Air Force Officers, Brett S. Bowers

Theses and Dissertations

Employee retention, while always a concern in the workplace, has become a greater challenge for organizations in recent years. Today’s working class has displayed a propensity to change jobs more rapidly than previous generations, exacerbating not only turnover rates but also the costs associated with them (Frankel, 2016). This challenge is especially relevant to the United States Air Force, which has experienced difficulty retaining young officers in recent years. The problems resulting from this voluntary turnover are exceedingly impactful to the military command structure, as senior leaders must work their way up from the lowest ranks. As such, the Air …

Attraction And Retention Of Minority Managerial Employees At Electrical Contractors, Ben F. Bigelow, Anthony J. Perrenoud, Anusree Saseendran

The Professional Constructor

Diversity in the managerial workforce in construction is limited, with a shortage of talent in the industry and the demand projected to grow over the next ten years. The challenge of attracting and retaining managerial talent is exacerbated for trade contractors as they have historically promoted management from the trades. This study explored differences, based on ethnicity, when it comes to factors that attract and retain managerial talent in electrical construction. Data was collected through a nationwide survey of management employees of electrical contractors. It was found that while some factors were influential for all ethnic groups, certain factors became …

Building Information Model-Based Quantity Takeoff – Leadership Support And Training, Morgan Tagg, James P. Smith, Jay P. Christofferson, Kevin R. Miller

The Professional Constructor

Building Information Modeling (BIM) plays an important role in the modern construction industry. BIM models are tools that help stakeholders perform a variety of functions including communication, visualization, trade coordination, and clash detection. A less commonly utilized functionality of BIM that shows strong potential to improve efficiencies and reduce error is model-based quantity take off (QTO). The literature identifies eight challenges to implementing BIM QTO. This paper focuses on the leadership and training elements inherent to two of the identified challenges – 1) New skills and training, and 2) reluctance of employees to adopt. Through semi-structured interviews with estimators, preconstruction …


Effects Of Organizational Trust And Project Delivery Variables On Bim User Confidence, Jason D. Lucas, Saw Sri Neeharika Vijayarao Sep 2019

Effects Of Organizational Trust And Project Delivery Variables On Bim User Confidence, Jason D. Lucas, Saw Sri Neeharika Vijayarao

The Professional Constructor

The use of Building Information Models (BIM) for construction planning has increased in all areas except for automated processes such as quantity take-off. Many model users lack confidence that a model, typically created by a third party, has accurate enough information in it to rely on the data for planning the project. This research is looking at how factors of organization trust and variables related to project delivery can raise user confidence in these situations. Factors of organizational trust were identified through a literature review. Two surveys were utilized to identify which factors were significant in raising user confidence. Finally, …

Systemic Risk In Financial Networks, Tathagata Banerjee Aug 2019

Systemic Risk In Financial Networks, Tathagata Banerjee

McKelvey School of Engineering Graduate Student Theses & Dissertations

In this dissertation, I have used the network model based approach to study systemic risk in financial networks. In particular, I have worked on generalized extensions of the Eisenberg--Noe [2001] framework to account for realistic financial situations viz. pricing of corporate debt while accounting for network effects, asset liquidation mechanisms during fire sales, dynamic clearing and impact of contingent payments such as insurance and credit default swaps. First, I present formulas for the valuation of debt and equity of firms in a financial network under comonotonic endowments. I demonstrate that the comonotonic setting provides a lower bound to the price …


Optimizing Impression Counts For Outdoor Advertising, Yipeng Zhang, Yuchen Li, Zhifeng Bao, Songsong Mo, Ping Zhang Aug 2019

Optimizing Impression Counts For Outdoor Advertising, Yipeng Zhang, Yuchen Li, Zhifeng Bao, Songsong Mo, Ping Zhang

Research Collection School Of Computing and Information Systems

In this paper we propose and study the problem of optimizing theinfluence of outdoor advertising (ad) when impression counts aretaken into consideration. Given a database U of billboards, each ofwhich has a location and a non-uniform cost, a trajectory databaseT and a budget B, it aims to find a set of billboards that has themaximum influence under the budget. In line with the advertisingconsumer behavior studies, we adopt the logistic function to takeinto account the impression counts of an ad (placed at differentbillboards) to a user trajectory when defining the influence measurement. However, this poses two challenges: (1) our problemis …

Correlation-Sensitive Next-Basket Recommendation, Duc Trong Le, Hady Wirawan Lauw, Yuan Fang Aug 2019

Correlation-Sensitive Next-Basket Recommendation, Duc Trong Le, Hady Wirawan Lauw, Yuan Fang

Research Collection School Of Computing and Information Systems

Items adopted by a user over time are indicative ofthe underlying preferences. We are concerned withlearning such preferences from observed sequencesof adoptions for recommendation. As multipleitems are commonly adopted concurrently, e.g., abasket of grocery items or a sitting of media consumption, we deal with a sequence of baskets asinput, and seek to recommend the next basket. Intuitively, a basket tends to contain groups of relateditems that support particular needs. Instead of recommending items independently for the next basket, we hypothesize that incorporating informationon pairwise correlations among items would help toarrive at more coherent basket recommendations.Towards this objective, we develop a …


Minimodal: Dimensional Domain Of Miniature Shipping Containers For Intermodal Freight Transportation, Lee Stapley Jul 2019

Minimodal: Dimensional Domain Of Miniature Shipping Containers For Intermodal Freight Transportation, Lee Stapley

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

This study explores the feasibility of miniature shipping container usage within existing intermodal transportation (IT) supply chains. Smaller intermodal container shipments may help realign freight shipments with the most efficient transportation mode, rail. These containers embolden the dimensional domain (DD) of shipping. The shipping container dimensional domain (container size variation and modal fluidity) is widespread and results in shipments that are often larger or more infrequent than needed. The DD impacts transport mode, shipping frequency, shipment velocity, intermodal supply chain accessibility, and regional shipping networks. This study suggests that container size impacts the DD and, therefore, mode choice. As miniature …

Longitudinal Analysis Of Perceived And Objective Airline Performance Quality, Kaetlyn Blocker, Javad Gorjidooz

Student Works

Commercial air carrier performance is a multivariable function, uniquely and substantially impacted by passenger's perception of negative employee behavior. High industry visibility, coupled with exponential social media growth, has provided the incredible potential to either widen or narrow the perception-performance gap. The present research conducts a rare longitudinal evaluation of objective airline performance quality in contrast with consumer perceptions of perceived airline performance and the dynamic changes occurring therein. Additionally, the implications regarding air carriers facing both objective and perceived performance challenges, as well as implications for the industry as a whole, are discussed. Utilizing nearly 30 years of objective …


Forecasting In Blockchain-Based Local Energy Markets, Michael Kostmann, Wolfgang Karl Hardle Jul 2019

Forecasting In Blockchain-Based Local Energy Markets, Michael Kostmann, Wolfgang Karl Hardle

Sim Kee Boon Institute for Financial Economics

Increasingly volatile and distributed energy production challenges traditional mechanisms to manage grid loads and price energy. Local energy markets (LEMs) may be a response to those challenges as they can balance energy production and consumption locally and may lower energy costs for consumers. Blockchain-based LEMs provide a decentralized market to local energy consumer and prosumers. They implement a market mechanism in the form of a smart contract without the need for a central authority coordinating the market. Recently proposed blockchain-based LEMs use auction designs to match future demand and supply. Thus, such blockchain-based LEMs rely on accurate short-term forecasts of …
