Performance Analysis: Using The Northern Sea Route As An Alternative To Traditional Routes, Liangkun Xu, Qing Yu

Journal of Marine Science and Technology–Taiwan

The grounding accident of M/V EVER GIVEN in the Suez Canal causes a catastrophic loss on shipping companies. Alternatively, previous studies have presented encouraging findings of the remarkable benefits of time and cost saving in the Northern sea route (NSR) due to extend the ice-free time and shorten the distance. Ships using the NSR could shorten as much as 40% of the sailing distance from China (Shanghai) to Europe (Rotterdam) compared with the traditional route via the Suez Canal. This paper investigates the economic potential of using the NSR as a cost-effective route in comparison with Suez Canal Route (SCR) …

Numerical And Approximate Analytic Solutions Of Second- Order Nonlinear Boundary Value Problems, Chein-Shan Liu, Jian-Hung Shen, Yung-Wei Chen

Journal of Marine Science and Technology–Taiwan

The shooting method consists of guessing unknown initial values, transforming a second-order nonlinear boundary value problem (BVP) to an initial value problem and integrating it to obtain the values at the right end to match the specified boundary condition, which acts as a target equation. In the shooting method, the key issue is accurately solving the target equation to obtain highly precise initial values. Due to the implicit and nonlinear property, we develop a generalized derivative-free Newton method (GDFNM) to solve the target equation, which offers very accurate initial values. Numerical examples are examined to show that the shooting method …

Numerical Investigation Of The Uncertainty Of Typhoon Wave Parameters Retrieval Using Hf Radar, Toan Duy Dao, Hwa Chien

Journal of Marine Science and Technology–Taiwan

The aim of this study was to identify the sources of uncertainties of typhoon wave field monitoring using HF radar and to quantitatively assess the bias of the wave parameters, such as significant wave height and mean period, retrieved under various conditions. The strategy was to apply a purely numerical simulation of the Doppler-range spectra and then compare the estimation results to the target. For the quantitative investigation, a numerical test-bed was established. The test-bed was used to simulate the Doppler spectra based on Barrick’s (1972) theory by using the input of the directional wave spectra. The typhoon wave spectra …

A Fused Data Based Real-Time Collision Warning System For Ferries In The Yangtze River, Xiaojia Liu, Ke Zhang, Han Xue, Yingtang Li

Journal of Marine Science and Technology–Taiwan

The risks for ferries in the Yangtze River are relatively high, as they frequently cross the main traffic flows, leading to more intersections with other upwards and downwards ships. Although some studies have developed many models to assess collision risks in the Yangtze River, collision warning studies on ferries are scant. Meanwhile, most of the current collision studies evaluate risk based on AIS data, which are incapable of providing real-time ship information as they are discrete-time series data. In this work, fused data combining radar and AIS data are applied in a real-time ship collision warning model to assess the …

Experimental Study Of The Effect Of A Solid Wing Conveyor On Marine Debris Collection, Erik Sugianto, Jeng-Horng Chen

Journal of Marine Science and Technology–Taiwan

Marine debris is a global problem that has not been resolved. This has encouraged the emergence of marine debris cleaning technologies, one of which is a conveyor ship. However, how effective conveyors are in collecting waste has not been studied. In this paper, experimental research on conveyors as marine debris collectors is investigated. The capability of catamarans with or without solid wing conveyors to collect marine debris is explored. Three kinds of marine debris collection models are used: no-wing conveyor, a 12.5-cm-long wing conveyor, and an 18.75-cm-long wing conveyor. Artificial marine debris (AMD) is spread on the water surface in …

Adding Equity To Transformative Agreements And Journal Subscriptions –The Read & Let Read Model, Arthur J. Boston

Faculty & Staff Research and Creative Activity

The transition towards open access to research articles has become a question of how, rather than why and the rise of transformative agreements has enabled publishers to strike agreements with large institutions and national research organisations to provide open access and authorship to their members. In this post, Arthur J. Boston puts forward an alternative Read & Let Read model, which could extend access beyond these limited groups and create a framework for more collaborative funding for access to open access research.

Impact Of Organizational Structure On Community Engagement Outcomes, Christy Arrazattee

School of Education Doctoral Projects - Higher Education

Community engagement has been embedded into higher education institutions since the early 1990s, yet scholars and practitioners still debate if there is an ideal reporting structure for coordinating offices (Jacoby, 2014). This study involved a quantitative analysis of 72 institutions who submitted information to the National Inventory of Institutional Infrastructure for Community Engagement survey (NI³CE – pronounced “nice”) between 2017 and 2020. Institutions were categorized by organizational structure (centralized vs. decentralized) and by reporting line (Academic Affairs, Student Affairs, Joint Academic Affairs/ Student Affairs, Outreach, and decentralized). Using the NI³CE inventory and scoring system, points were awarded to institutions based …

I’M Not That Needy: Black Students’ Perceptions Of Food Assistance And The Impact Of Self-Categorization On Campus Food Pantry Utilization, Catherine M. Jermany

School of Education Doctoral Projects - Higher Education

The purpose of this qualitative study was to identify which student groups Black students perceive as needing food assistance, to explore how Black students’ perceptions of students in need impacts their decision to utilize the on-campus food pantry at California State University, Dominguez Hills (CSUDH), and to identify the circumstances that influence Black students’ self-categorization. Nine, Black-identified students enrolled at CSUDH participated in semi-structured interviews that were transcribed and coded using a grounded theory approach. Results of the study revealed that Black students generally perceived low-income students, unemployed or overemployed students, students experiencing food insecurity, and students with non-traditional housing …

Educators’ And Parents’ Attitudes Toward The Inclusion Of Students With Emotional And Behavior Disorders, Shannon L. Howze

Dissertations

Educating students with emotional and behavior disorders (EBD) has historically been a difficult task for educators (McKenna et al., 2021). The general education setting comes with many barriers when attempting to include students with EBD to the equation. Parents are instrumental to the success of their students with EBD regardless to the setting. Educators may lack in the skills needed to communicate, educate, and understand students with EBD. Without educators and parents collectively communicating and collaborating, students with EBD will not have the opportunity to have the positive experiences and outcomes to be successful. Applying the theoretical frameworks of Bandura’s …

Using The Social-Ecological Model To Better Understand Sexual Assertiveness Among Undergraduate Women At An Institution Of Higher Education In The Southeastern United States, Lisa Wright

Dissertations

This study examined sexual assertiveness among female undergraduate students at an institution of higher education in the southeastern United States from the context of the social-ecological model. An online survey instrument examined sexual assertiveness, sexual communication self-efficacy, campus climate, and sexual scripts. Structural equation modeling was used to examine the relationships between these variables and all variables significantly predicted sexual assertiveness individually, but when examining the relationships collectively, only sexual communication self-efficacy and campus climate remained significant predictors of sexual assertiveness.

The Impact Of A Five-Day Number Sense Intervention On High School Student's Quantitative Reasoning Skills And Self-Efficacy, Rebecca Steele-Mackey

Dissertations

Understanding numerical quantities and applying this knowledge in practical applications is essential throughout life. A well-developed number sense comes from learning foundational skills and continuing to rely on these skills and concepts in higher mathematical education as well as in adulthood. Prior research shows that K-8 students lack a conceptual understanding of fraction, decimal, and percentage concepts (NCTM, 2009). While there is literature that identifies a deficit in these mathematical areas, there is a need to examine possible activities and interventions that can be performed throughout secondary education courses that support growth in students' conceptual understanding of rational number concepts. …
