Give Them Something To Talk About: The Role Of Dialogue In Mentoring Relationships, Dawan Coombs, Kate Goodwin

Faculty Publications

An effective mentor/protégé relationship is essentially dialogical. Given that the mentor learns as the beginner learns, the mentor needs to take a dialogical stance to promote open conversations and investigation. Journals, blogs, observations, and subsequent debriefings help both the mentor and the beginner to learn much about teaching and learning.

Enabling Connections In Postgraduate Supervision For An Applied Elearning Professional Development Programme, Roisin Donnelly

Journal Articles

This article describes the practice of postgraduate supervision on a blended professional development programme for academics, and discusses how Connectivism has been a useful lens to explore a complex form of instruction. By examining the processes by which supervisors and their students on a two-year part-time masters in Applied eLearning negotiated the blended approach adopted to supervision, it illustrates the conditions that enable connections to occur and flourish. The socio-technical context for supervision was supported using learning technologies (vle, research wikis and ePortfolios), small group supervision (two to three supervisors and students) and traditional individual supervision. Qualitative data were obtained …

Ultrasound For Improved Crystallisation In Food Processing, N. Misra, Navneet Deora, Brijesh Tiwari, Patrick J. Cullen

Articles

Within the food industry, controlling crystallisation is a key factor governing food structure, texture and consumer appeal, with some foods requiring the promotion of crystallisation in a controlled manner (e.g. chocolate) and others a check (e.g. in honey). Sonocrystallisation is the application of ultrasound energy to control the nucleation of a crystallisation process. The use of power ultrasound provides a non-invasive approach to producing crystals with desired properties. Sonocrystallisation facilitates process control, primarily by modulating crystal size distribution and morphology. This paper details the governing mechanisms of sonocrystallisation. Proven and potential applications of the process in foods, including chocolates, honey, …

Making Connections: Networked Mindmaps As A Student Centred Assessment For Learning., Barry Ryan

Articles

Engaging students is a difficult task faced by all academics. Student engagement can be achieved by giving ownership of their learning back to the student and by carefully aligning the assessment methodology to the students learning and future employability. To promote learning ownership in this case-study, a group of final year students were involved in the design of the delivery (‘flipped classroom’) and assessment strategy (‘flipped assessment’) of the curriculum. Upon reflection, students noted a deep understanding of their self-selected topic by taking ownership of their learning and their ‘assessment for learning’ within the bounded learning environment. Additionally, students enhanced …

Line Up, Line Up: Using Technology To Align And Enhance Peer Learning And Assessment In A Student Centred Foundation Organic Chemistry Module., Barry Ryan

Articles

This paper describes how three technologies were utilised in combination to align student learning and assessment as part of a case study. Multiple choice questions (MCQs) were central to all these 10 technologies. The peer learning technologies; Personal Response Devices (a.k.a. Clickers) and PeerWise (http://peerwise.cs.auckland.ac.nz), were implemented to achieve scaffolded, self-directed independent learning by the students which aligned to the assessment methodology through creating, analysing, answering and discussing multiple choice questions. Personal response devices enhanced in-class activity involvement, whilst PeerWise provided structure and support for independent student learning through 15 defined outside class activities. An associated technology, online MCQs hosted …

A Walk Down The Red Carpet: Students As Producers Of Digital Video-Based Knowledge., Barry Ryan

Articles

Disengaged and apathetic students are common in many undergraduate classrooms. Learning to these students is a passive process, typified by a consumer-like attitude. One approach to engage students, and enhance the learning experience, is to integrate active learning into the curriculum. The purpose of the pedagogical evaluative study described here was to investigate if student researched, designed and created digital video could act as a viable reusable peer learning resource. Although the use and integration of technology was central to the scope of this project, other ideas such as threshold concepts, the requirement for both active and authentic social constructivist …

Legal, Technical, And Economic Challenges In Integrating Renewable Power Generation Into The Electricity Grid, Timothy P. Duane, Kiran H. Griffith

San Diego Journal of Climate & Energy Law

This Article addresses the legal, technical, and economic challenges of integrating high levels of renewable power generation into electrical grid system operation. Part II shows that the primary integration challenge is reducing the total costs of integration and allocating the costs of integration in a hybrid regulatory structure, which presents different institutional impediments than traditional cost-of-service ratemaking or rate-of-return regulation. We demonstrate that the primary impediment to improved integration is a failure to make the critical policy choice about how such costs will be allocated. Part III describes and analyzes the BPA-wind dispute in order to evaluate the adequacy of …

Exploring The Use Of Web 2.0 Tools To Support Knowledge Sharing Within The Non-Profit Sector, Christina Shannon

Students Learning with Communities

This project will investigate the challenges of knowledge sharing and communication in non-profit organizations with a high dependence on volunteers. Projects of this type typically rely heavily on the knowledge of the volunteers for success and while many projects have some mechanisms through which they communicate and share knowledge such as a web presence, typically the knowledge is disparate, highly tacit, embedded in the people involved. A scattered approach is typical with knowledge and information on several different forums managed by several different people with no obvious connection. There is unlikely to be a cohesive, coherent approach in place to …

Quasi-Experimental Evaluation Of Undergraduate Learning In A Multidimensional Wellness Course, Kristi Leonard

Dissertations and Theses @ UNI

Introductory wellness courses are common among American institutions of higher education. These courses are typically of a unidimensional approach, focusing on just the physical component of wellness. Some wellness educators would argue that a multidimensional approach is a richer and more valuable learning experience. Furthermore, technology has played a larger role in wellness education, as it is being created, developed, and implemented into the field. Therefore, college wellness educators and curriculum designers need to determine the implications for both online and face-to-face instructional methods in their execution of teaching the holistic concept of wellness to their students.

The purpose of …

Postmodern Humanism And The "Exhaustion Of Easy Life", Mason Beets

Dissertations and Theses @ UNI

The twenty-first century appears to herald a new epoch, one in which religion and other similar belief systems appear to have run their course. However, this should not necessarily mean that other forms of spirituality and interconnectedness must fade away. Within America, there is a humanistic undercurrent that is gaining strength within our postmodern condition, even as we begin to challenge several of the tenets of postmodernity itself. The groundswell of American humanism has a notable and wholly unintended effect: it ideologically rehabilitates modes or vehicles of thought that might otherwise be labeled as defunct, or inapplicable to the changing …

Playing By New Rules: Board Games And America's Cold War Culture, 1945-1965, Matthew John Sprengeler

Dissertations and Theses @ UNI

This thesis examines the domestic culture of the United States during the first two decades of the Cold War, using popular games as an interpretive tool to expand our understanding of the changes that took place. Four board games which were popular during the 1950s – Scrabble, chess, Clue, and Risk – explain some of the anxieties and evolutions in mass culture. Scrabble illustrated the nation's growing respect for expertise and, along with game theory, the hope for intellectual solutions to the country's problems. Chess, often seen as a symbol of the Cold War, served as a proxy battlefield for …

Recalcitrant Arguments, Kiranjeet Kaur Dhillon

Dissertations and Theses @ UNI

On January 26, 2011, Reuters photojournalist Amr Abdallah Dalsh took an image of a unknown veiled woman gesturing at Dalsh and his camera. Using TinEye, a reverse image search engine, I found that 86 circulations and 22 recirculations of the photo were primarily in the United States. US graphic artist Nick Bygon created one of the recirculations, which primarily appeared on US blogs. The photo achieved this level of circulation in the US because it is consistent with, and therefore legible within the symbolic language, of the liberal democratic order. Similar to “Migrant Mother” and “Tank Man”, the photo is …

Longitudinal Analysis Of Perceived Body Image, Sport Commitment, Burnout, And Athletic Injury, Erik Chaouch

Dissertations and Theses @ UNI

Injury is a risk that all athletes face while participating in sport. How injuries affect athletes perceived body image, sport commitment levels, and burnout levels are not yet fully understood. Athletes are aware of what the media portrays an athlete as, aware of what peers think an athlete should look like, and even have their own pre-conceived notions as to what an athlete’s body should look like. Many athletes perceive their bodies to be appropriate for their sport, yet there is dissatisfaction with their own bodies in the context of what is socially considered to be attractive. A distorted body …

Long-Term, Low-Dose Exposure Of People Residing In Arsenic Affected Areas Of Iowa: A Cross-Sectional Analytical Study, Junu Shrestha

Dissertations and Theses @ UNI

Arsenic contamination in the ground water source is a major problem throughout the world. Epidemiological studies show that long-term arsenic exposure in drinking water, even at low concentrations, can lead to chronic toxicity problems and negative health outcomes. In the United States, private wells are not mandated to comply with the drinking water standards that piped water is, putting many people at risk. This study focused on monitoring of arsenic contamination of private well water, hair samples, and questionnaire based surveys. Of the 260 private well owners selected from 13 counties in Iowa who were invited to participate in the …

From Saeter To Sod: Single Women Homesteaders Of Norwegian Descent Farming Their Land In Dakota Territory, 1862-1929, Sara Marie Skindelien

Dissertations and Theses @ UNI

On May 20, 1862 Congress signed into effect the Homestead Act which provided 160 acres of surveyed government land to any citizen over the age of twenty-one and who was a head of household. One of the most historical aspects of this act was that it allowed single women the opportunity to own land. Not only were native-born women taking advantage of such a lucrative offer, but the women of Norway saw just the opening they needed to venture out on their own. They joined thousands of their countrymen across the Atlantic to find a bit of land where they …

A Study Of The Effect Of Organizational Communication Cultures On Interorganizational Collaboration Of Crisis Response, Laura Pechta

Wayne State University Dissertations

Recent history has indicated that crises are becoming more frequent rather than exceptional events. Dozens of organizations, often with very different missions, methods, technologies and cultures, are called upon to coordinate activities in order to mitigate the crisis and assist in recovery efforts. Although several interorganizational coordination perspectives and strategies have been proposed, they have neglected to examine how different organizational communication cultures of crisis response organizations involved in an Emergency Operations Center (EOC) may affect crisis collaboration efforts. Previous studies have also disregarded the important distinction between crisis coordination and crisis collaboration and the challenges and benefits of each …

An Investigation Into The Role Of Cfia 3' End Processing Complex In The Termination And Initiation/Reinitiation Of Transcription, Nadra Al-Husini

Wayne State University Dissertations

In budding yeast, as in higher eukaryotes, transcription of protein coding genes is executed by a highly specialized, conserved polymerase called RNA polymerase II (RNAPII). The transcription cycle of RNAPII has four major steps: initiation, elongation, termination, and reinitiation. The successful accomplishment of each of these steps requires a number of accessory factors. Many of these factors operate at multiple steps in the transcription cycle. The major focus of this study was to examine the function of Clp1, which is an RNA processing factor operating at the 3′ end of genes, in the transcription cycle. Clp1 is one of the …

Social Support And Health Behaviors, Bryan Michael Kingry

Wayne State University Dissertations

Empirical evidence exists showing a correlation between social support and health behaviors. However, does social support act the same across several health behaviors? The purpose of this study was to determine if social support has an impact across diet, physical activity and smoking in adults. The participants were 2,821 adults over the age of 40 from the National Health and Nutrition Examination Survey (2005-2006, NHANES III). Multiple regression models were used to explore such a correlation. The findings suggest that social support does not act the same across varying health behaviors. The findings also suggest that educational attainment was the …
