Plymouth Business School

This paper aims to examine the main practices that shape sustainable port development in the context of Korean ports and generalize a typology of port–stakeholder decision framework for sustainable port development. First, the main practices of sustainable port development were examined through a comprehensive literature review and a holistic conceptual framework underpinned by sustainable development and stakeholder management theories. Semi-structured interviews were then conducted with 67 port managers in Korea. Lastly, FAHP was performed based on inputs from 18 port managers to analyze the priorities of the proposed sustainable port development practices. It was found that all proposed practices should …

Commercial Energy Demand Forecasting In Bangladesh, Ar Anik, S Rahman

Plymouth Business School

Although both aggregate and per capita energy consumption in Bangladesh is increasing rapidly, its per capita consumption is still one of the lowest in the world. Bangladesh gradually shifted from petroleum-based energy to domestically sourced natural-gas-based energy sources, which are predicted to run out within next two decades. The present study first identified the determinants of aggregate commercial energy and its three major components of oil, natural gas, and coal demand for Bangladesh using a simultaneous equations framework on an annual database covering a period of 47 years (1972–2018). Next, the study forecast future demand for aggregate commercial energy and …

Challenges Of Virtual Rds For Recruitment Of Sexual Minority Women For A Behavioral Health Study, Deirdre Middleton, Laurie A. Drabble, Deborah Krug, Katherine J. Karriker-Jaffe, Amy A. Mericle, Tonda L. Hughes, Ronaldo Iachan, Karen F. Trocki

Faculty Research, Scholarly, and Creative Activity

Respondent-driven sampling (RDS) is an approach commonly used to recruit nonprobability samples of rare and hard-to-find populations. The purpose of this study was to explore the utility of phone- and web-based RDS methodology to sample sexual minority women (SMW) for participation in a telephone survey. Key features included (i) utilizing a national probability survey sample to select seeds; (ii) web-based recruitment with emailed coupons; and (iii) virtual processes for orienting, screening, and scheduling potential participants for computer-assisted telephone interviews. Rather than resulting in a large diverse sample of SMW, only a small group of randomly selected women completed the survey …

The Impact Of Short Papers On Clinical Decision Making Skills Of Nursing Students, Tara R. Hayes

Theses

Clinical decision making and critical thinking are fundamental skills to ensuring the success of undergraduate nursing students. Nursing faculty, and specifically clinical nursing faculty, are responsible for encouraging the development of these types of skills as students work in direct patient care. Traditional methods of clinical evaluation include lengthy case studies, concept mapping, and discussion board participation. While these methods have been in effect for some time, clinical short paper assignments are a fresh, innovative way to challenge students as they refine their critical thinking and clinical decision making abilities. No statistically significant difference was found between the perceived level …

Building A Pipeline Of Bilingual Slps To Serve Dual Language Learners: An Inclusive Model Of Interprofessional Education, Sonja Pruitt-Lord, Alicia Escobedo, Jennica Paz, Carol Robinson-Zañartu

Teaching and Learning in Communication Sciences & Disorders

Speech-language pathology graduate programs do not reflect equity across racial and ethnic groups. Training programs must adopt an anti-racist stance and intentionally and strategically plan for equity and inclusion of students and professionals who are Black, Indigenous and Persons of Color (BIPOC). Retention of minoritized students must be supported by inclusion efforts. The authors review systems of support essential to the recruitment and retention of BIPOC students in graduate programs. Through funding support from a grant, the authors developed a model of training bilingual SLP students to work with dual language learners through an inclusive model of interprofessional education. Finally, …

The study investigated the characteristics and practices of the diverse teaching-learning contexts involving the participant, the intersection of those settings, and the student's perceptions, feelings, and thoughts about the value of music experiences in those settings for his musical growth. The study …

Cultivating The Cyborg Voice: Technology In The Creative Writing Classroom, Rebecca Valley

Journal of Creative Writing Studies

This article takes a critical look at pieces generated from a capstone project in a recent mixed-genre Intro to Creative Writing workshop. It was inspired by an open-ended creative project asking students to use technology to generate unconventional works of fiction, poetry, memoir, and theatre. Writer and educator Rebecca Valley's hope when assigning this project was to encourage students to innovate and step outside their standard forms. But beyond mere innovation of form, students surprised her in their capacity to use technology to hybridize their authorial voices – rather than merely changing the form of their own words, they became …

Writing Here, Writing Now; Making Sense Of It All: Examining Cultural And Historical Context In The Introductory Creative Writing Class, Oindrila Mukherjee

Journal of Creative Writing Studies

Writers are a product of their environment. The time and place in which they live inevitably impact what they write, why they write, and how they write. I assign a brief reflection essay in my Introduction to Creative Writing class which asks students to consider social, historical, and cultural factors that influence the poetry, fiction, or nonfiction they write, either directly or indirectly. It encourages students to identify patterns in their writing, and to reflect on what it means to live in a specific part of the world at a specific time in history. This makes them more aware of …

(Re)Considering Craft And Centralizing Cultures: A Revision Of The Introductory Creative Writing Workshop, Zoë Bossiere, Micah Mccrary

Journal of Creative Writing Studies

This article explores options for introductory creative writing curricula that allow for and encourage a greater consideration of personal identity and audience on the part of the student-author. It reaches toward possibilities for revising the introductory creative writing course as a space for student-authors to not only consider the cultural positions of the professional authors they study, but also the ways in which their own subject-positions influence their writing practices, craft choices, and understandings of genre. The article overall proposes a holistic revision to the standard, introductory creative writing curriculum, moving student-authors beyond considerations of “good” creative writing, and toward …

Anti-Corrosion Protection Of Metal Parts Of Transportation Equipment With A Polymer Coating Based On Epoxiurethane, Aida Barkhanadjyan, Ravshan Khakimov, Botir Ibragimov, Oybek Vafayev, Dmitriy Ayrapetov

CHEMISTRY AND CHEMICAL ENGINEERING

Automotive vehicles are constantly exposed to corrosion processes, and the durability of metal parts depends on the intensity of corrosion. The loss of metals from corrosion is 8-10% of the initial metal mass. In total, losses from corrosion are 4-6% of national income in many countries. This indicates the need for research and the importance of scientific and technical work in this area. This can be achieved by developing a technology for producing anticorrosive compounds and applying them as protective coatings. The anticorrosive protection of a coating synthesized on the basis of local raw materials - epoxyurethane with an additive …

On The Possibility Of Obtaining Effective Phosphoric Fertilizers As A Result Of Interaction Of Phosphorite-Containing Waste With Activated Glauconite Sands, Nargisa Takhirova, Fazlidin Khudoyberdiev, Shahlo Daminova

CHEMISTRY AND CHEMICAL ENGINEERING

These studies are devoted to the study of the chemical properties obtained as a result of chemical activation of glauconite and further neutralization of activated glauconite by waste products of phosphorite concentrates. Based on the results of X-ray structural studies of the obtained products, it is possible to obtain granular complex fertilizers after adding phosphorites to the system. Activation with mineral acids (nitric or sulfuric) should be carried out to accelerate the transformation of minerals from glauconite sands into an easily digestible form. Since the obtained compounds form an acidic environment, it is necessary to neutralize them. The neutralization process …
