Note On Fuel Consumption In Ocean Container Shipping: Bounds On Fuel Usage, Manwo Ng

Information Technology & Decision Sciences Faculty Publications

This paper contributes to the literature by deriving upper and lower bounds on the fuel consumption in container shipping. The bounds are derived from sailing distances, port times, and the possible arrival times at ports/ the berth windows negotiated between the ocean carrier and the port operators. Crucially, the derived bounds can be used in conjunction with any of the common fuel consumption functions proposed in the literature. This latter is especially important since currently there is no consensus on a specific functional form for the fuel consumption function. The behavior of the bounds will be illustrated with numerical examples.

High-Dimensional Iv Cointegration Estimation And Inference, Peter C. B. Phillips, Igor L. Kheifets

Research Collection School Of Economics

A semiparametric triangular systems approach shows how multicointegrating linkages occur naturally in an I(1) cointegrated regression model when the long run error variance matrix in the system is singular. Under such singularity, cointegrated I(1) systems embody a multicointegrated structure that makes them useful in many empirical settings. Earlier work shows that such systems may be analyzed and estimated without appealing to the associated I(2) system but with suboptimal convergence rates and potential asymptotic bias. The present paper develops a robust approach to estimation and inference of such systems using high dimensional IV methods that have appealing asymptotic properties like those …

Statistical Discrimination And Duration Dependence In A Semistructural Model, Ismail Baydur, Jianhuan Xu

Research Collection School Of Economics

This article develops a job-search model with unobserved worker heterogeneity and learning about worker types from unemployment duration. The model features negative duration dependence that stems from unobserved heterogeneity, skill depreciation, and statistical discrimination. We estimate job-finding rates implied by our model using microlevel data from the Current Population Survey. We find that removing interview costs counterfactually, thereby eliminating statistical discrimination, substantially increases the job-finding rates of the long-term unemployed. The performance of low-skill workers at the interview stage with discriminating firms plays a key role in explaining our counterfactual result.

Implications Of Alternative Communications And Sensing Technologies For Implementing Variable Speed Limit Control Through Connected Vehicles: Sag Curve As A Case Study, Reza Vatani Nezafat, Mecit Cetin, Elizabeth Williams, George F. List

Civil & Environmental Engineering Faculty Publications

Connected vehicles (CVs) will enable various applications to improve traffic flow. This paper's focus is to investigate how the potential implementation of variable speed limit (VSL) through different types of communication and sensing technologies on CVs makes it possible to mitigate congestion at a sag curve bottleneck. A VSL algorithm is developed and implemented in a simulation environment for controlling the inflow of vehicles to a sag curve to minimize delays and increase throughput. Both vehicle-to-vehicle (V2V) and infrastructure-to-vehicle (I2V) options for CVs are investigated when implementing the VSL control strategy in a simulation environment. Also, for measuring traffic density …

The Classification Paradox: Historically Black Colleges' And Universities' Complex Relationship With Inequitable Experiences With The Carnegie Classification System, Felecia Commodore

Educational Leadership & Workforce Development Faculty Publications

[Introduction] Higher education in the United States boasts of diverse institutional offerings to students. From community colleges to well-resourced liberal arts institutions, this diverse array of institutions and types has created a system commonly viewed as having a variety of access points for those seeking higher learning. Higher education stakeholders can argue that this diversity is a strong suit of American higher education, but an argument can also be made that this same institutional diversity laid the groundwork for systemic racism and inequities within the higher education system.

These inequities exist through various intersecting systems and practices, such as the …

On The Optimal Forecast With The Fractional Brownian Motion, Xiaohu Wang, Jun Yu, Chen Zhang

Research Collection School Of Economics

This paper investigates the performance of different forecasting formulas with fractional Brownian motion based on discrete and finite samples. Existing literature presents two formulas for generating optimal forecasts when continuous records are available. One formula relies on a history over an infinite past, while the other is designed for a record limited to a finite past. In reality, only observations at discrete time points over a finite past are available. In this case, the forecasting formula, which has been widely used in the literature, is the one obtained by Gatheral et al. (2018) that truncates and discretizes the formula based …

Ultimately, despite higher education being perceived as a progressive industry and having legislature in place to combat gender disparities, leadership positions are not reflective of gender distribution …

A Novel Dual Configuration Dart/Uhplc-Ms/Ms System For The Rapid Analysis Of Psilocybin-Containing Mushrooms And Other Seized-Drug Submissions, Aron R. Jaffe

Master of Science in Forensic Science Directed Research Projects

The use and availability of controlled substances is highly dynamic. When a classical or novel psychoactive substance becomes popular, an influx of seized-drug evidence submissions closely follows, contributing to an ever-growing backlog of exhibits awaiting identification. The need for inclusive, rapid, and robust analytical methods is apparent, as demonstrated by recent growth in hallucinogen use. Psilocybin and psilocin, among other entheogens, have become increasingly popular and an increase of psilocybin mushroom seizures by law enforcement has followed. The structural similarity and thermal lability of many entheogens preclude their identification using many conventional analysis techniques. A DART and UHPLC were interchangeably …

Challenges In Diagnosing Adhd: Discrepancies Between Behavioral And Executive Functioning Indicators, Amneet Kaur

Selected Full Text Dissertations, 2011-

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, hyperactivity, impulsivity, and executive function deficits. The DSM-5-TR (American Psychiatric Association [APA], 2022), along with the DSM IV-TR (APA, 2000) and the DSM-5 (APA, 2013), emphasizes the behavioral aspects of ADHD while giving scant attention to executive function deficits, complicating diagnosis for clinicians and potentially resulting in misdiagnosis. This study seeks to identify the prevalence of ADHD diagnoses based on psychological evaluations where data from behavioral rating scales meet DSM criteria, but data from executive functioning measures do not, suggesting potential misdiagnosis. In this descriptive mixed design content …

Data was collected using an online survey of 76 licensed psychologists’ training in nutrition and use of nutrition counseling. Findings …

Teaching Children Consent Skills Through The Lens Of Personal Boundaries And Bodily Autonomy, Prerana Atreya

University of the Pacific Theses and Dissertations

Sexual violence is a public health and safety problem affecting many children across the United States. One preventative tool the public health department uses to mitigate the high prevalence rates and harm of sexual violence is teaching consent skills to children. Previous research has demonstrated that behavior analytic principles effectively teach other important safety skills (e.g., abduction prevention, gun safety, and poison safety). Thus, it is possible that using behavioral technologies to teach consent skills will show similar effectiveness as teaching safety skills. The current study’s purpose was to evaluate the effectiveness of using behavioral skills training (BST), video modeling, …

Exploring Women`S Perceptions Of Climate Change Impact On Agriculture, Health & Food Security In Upper Hunza, Gilgit Baltistan, Ambreen, Elina Nizar Ali, Taiba Yar Baig, Fozia Parveen

Institute for Educational Development, Karachi

The Hindu Kush Himalayan (HKH) region, renowned for its towering mountains and major river basins, sustains nearly 1.4 billion people worldwide and is pivotal to global food production. Glacial melt from the HKH region nourishes agriculture, livestock, and horticulture, supporting the livelihoods of mountain communities. However, climate change is accelerating the melting of glaciers, and shifts in wet seasons significantly impact food security in these communities. Sectors such as water resources, agricultural land, and human health, particularly women’s health, are significantly affected by these changes. For centuries, agriculture has been the backbone of Gilgit-Baltistan’s economy, with over 70% of livelihoods …

Discourses That Undermine Union Movements: A Multimodal Analysis Of Union-Busting Videos, Theresa A. Catalano, Julia Schleck

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Labor unions in the United States have experienced decades of decline, but recent years have seen a rebirth of union campaigns and successes. Because unions are once again becoming a threat to large companies, it is reasonable to assume that efforts to discourage organizing efforts will increase and become even more robust in the near future. Although traditionally, companies have worked to suspend union organizing through captive audience meetings in which unions were discussed via verbal or written modes, more recent means of reaching workers with anti-union messages incorporate a variety of communication strategies to get the message across. As …

Pricing, Decarbonization, And Green New Deals, David M. Driesen, Michael A. Mehling

William & Mary Environmental Law and Policy Review

This Article evaluates an emerging literature claiming that carbon pricing (emissions trading or carbon taxes) has not performed very well and therefore cannot be the basis for the sort of transformative change now required to address the climate crisis. This is an important claim, as carbon pricing has been viewed as being at the heart of global efforts to address one of our most important contemporary problems.

We provide theoretical and empirical support for these critics’ claim that carbon pricing by itself cannot catalyze the technological transformation now required, and that other approaches have done and will likely do better. …

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …

Method: The current study collected data from 127 undergraduate students aged 18-25. A survey was given with questionnaires assessing demographics such as age, sex, and gender, as well as the frequency of ACEs, BDD symptoms, and obsessional beliefs. Pearson’s correlation analysis was …

Unveiling The Pathways: The Effects Of Mindfulness And Recreational Psychedelic Experiences On Well-Being; The Mediating Roles Of Non-Dual Awareness, Pro-Sociality, And Meaning In Life., Sebastian Ehmann

West Chester University Master’s Theses

Contemplative practices and psychedelic experiences have demonstrated significant benefits for psychological health and general human flourishing. Both practices share neuroscientific (i.e., cognitive flexibility), psychological (i.e., insight), and phenomenological (i.e., self-loss) overlap, but the combined effects remain underexplored. This study aimed to address this gap by examining the influence of drug-induced ego-dissolution and dispositional mindfulness on subjective well-being while testing the potential mediating role of compassion, meaning in life, and non-dual awareness (NDA; awareness without the typical subject-object dichotomy). The initial hypothesis posited that selfless experiences and mindfulness cultivate non-dual embodied cognition, leading to increased compassion and meaning and, in turn, …
