Adults\u27 Attachment Representations and \u27Mindrelated\u27 Descriptions of Romantic Partners
No full textAdults\u27 attachment representations were analyzed in relation of their use of mental (compared to physical and/or behavioral) attributes to describe their (a) primary caregiver and (b) their current romantic partner. Significant associations were found between adults\u27 attachment representations and their use of mental attributes to describe their romantic partner
Diving behavior and thermal habitats of gravid hawksbill turtles at St. Croix, USA
No full textKnowledge of an animal’s behavior during particular life history stages can provide insights into habitat selection, and this can have important conservation implications. Gravid hawksbill turtles spend the internesting interval resting on the seafloor, but their diving behavior has only been previously examined in shallow-water habitats. We examined depth use of gravid hawksbills in a location of variable bathymetry to determine if hawksbills engage in deeper diving if deeper waters are available. We attached archival time-depth recorders onto hawksbills nesting at Sandy Point National Wildlife Refuge, St. Croix, US Virgin Islands, where the neritic zone ends within 500 m of the shoreline. We recorded seven internesting intervals from five individuals. Internesting intervals were characterized by long dives (mean 24.2 ± SD 22.3 min) to a constant depth, consistent with seafloor resting in a spatially restricted residence area. There was little variation in the water temperatures at all depths occupied (mean 29.06 ± SD 0.43 °C). Two turtles attained the deepest recorded dives for gravid hawksbills (95.1 and 84.4 m) and sometimes remained at depths greater than 60 m for up to 30 min. Although we recorded instances of relatively deep diving for the species, the overall pattern of seafloor resting and infrequent diving was consistent with hawksbills in other ocean basins with different offshore habitats. We propose that benthic resting is common behavior for gravid hawksbills globally, and protection of benthic habitats near the nesting beach should be a management priority
Unfolding case studies: Discovery of ways to stimulate students’ deeper learning
No full textAbstract
Background
The Future of Nursing Report (2010), and National League for Nursing (NLN) (2011) reveal an expectation that nursing programs integrate strategies for academic progression from beginner to advanced nursing. Improving nursing curricula rely on integrating teaching and learning principles that reflect a student-centered approach supported by evidence (Ironside \u26 Hayden-Miles, 2012). An idea to facilitate students to “think like a nurse” as described by Tanner (2006), is to provide deeper learning experiences for students by transforming students’ reflections about their clinical and simulation experiences into unfolding case studies that can be used in the classroom.
Purpose
The purpose of this research project is to determine ways to integrate unfolding case scenarios that reflect students’ clinical and simulation experiences throughout the nursing curriculum.
Methods
Unfolding case studies that evolve in complexity from beginner to advanced expertise in nursing courses include an actual patient situation leveled in complexity from beginning to advanced content. The patient situations are video recorded and guiding questions are provided in class to stimulate students’ small group discussions about the patient situations. Students who attend each clinical class and view the video and participate in the discussion of the unfolding case study will be invited to participate in focus group sessions to share their perceptions of growth and learning related to the case study content. The focus group sessions will be audio recorded for approximately 60 minutes. Field notes will be recorded to add clarity and insight to communication shared by the students. This study captures a new holistic inter-professional approach to end of life care where an Advanced Care Planning team is included in one of the higher level course case study scenarios. Triangulation using test question analyses for this study is intended to validate if there will be students\u27 deeper understanding of the complexity the patient’s situation. Test questions related to content in the case studies will be taken from the comprehensive exam for each of the clinical courses. The comprehensive exam test questions reveal validity and reliability according to a test item analysis report.
Results and Conclusions
The unfolding case studies implementation and data collection are in process this spring semester. The focus groups will provide interaction that not only will include the students\u27 actual words, but also non-verbal communication that may enhance exchanging of perceptions. Test question results will reveal students\u27 knowledge, comprehension, application, and analysis of the content
J-Holomorphic Curves in Rough Almost Complex Structures
No full textA pseudoholomorphic curve, or J-holomorphic curve, is a differentiable map from a Riemann surface to a manifold with almost complex structure J, that satisfies an analogue of the Cauchy-Riemann equations. When J is smooth, pseudoholomorphic curves have well-known regularity and uniqueness properties. I will survey what can happen when J is only continuous or satisfies a Hölder condition
Modeling the Spread of Influence in Social Networks
No full textSocial networks play an important role in connecting people and facilitating human social interaction. Influence can spread through a social network. “Word-of-mouth” and “viral marketing” effects have been widely exploited to promote new products and technological innovations. For example, when an individual adopts a new product and finds it useful, she or he would recommend it to her or his friends and colleagues. One of this individual’s friends takes the advice, and may also feel excited about the product and spread the words about it to her or his own friends. In such a way, social influence can help diffuse new products or ideas. Modeling the spread of influence in social networks is valuable to computer science because of its relevance to digital networks (e.g., online social networks), but this research also holds importance in other fields, such as epidemiology, physics, and social sciences. The goal of this work is to derive a mathematical model that can accurately predict the influence of individuals in social networks. Such an accurate model can help computer scientists in designing new network protocols, structures, and policies to facilitate the spread of influence or information. Previous works on modeling the spread of influence assume the status of a single node in the network is independent of the status of other nodes in the network. In social networks, this is not true. For example, two friends in a social network tend to both either favor a product or reject it, meaning that the two individuals are spatially related to each other. In our work, we investigate the spread of influence in social networks using a Markov model, which assumes that neighboring nodes are spatially dependent on each other. To simulate the spread of influence in a social network, we use several generated network topologies and a real co-authorship network of scientists working on network theory, where the relationship between nodes is that author X wrote a joint work with author Y. We develop simulation tools in C++ to replicate influence diffusion through these networks. Our results show that our proposed Markov model predicts the spread of influence in a social network better than previously proposed models. To the best of our knowledge, this is the first attempt in studying the spatial dependence among nodes to describe influence dissemination.http://opus.ipfw.edu/stu_symp2017/1042/thumbnail.jp
Temperature tolerance of filamentous cyanobacteria from Indiana Dunes State Park
No full textBiological soil crusts (BSCs) are associations between microorganisms and the surface of the soil that occur in relatively undisturbed soils exposed to sunlight. They have been shown to stabilize soils and contribute to nutrient cycling in otherwise barren soils. Cyanobacteria are important microorganisms in BSCs because they initiate their development, serve as primary producers, and provide stability for the BSC microbial ecosystem. BSCs are known for their presence in open areas such as deserts, although they can be found in the more temperate environment of the Indiana Dunes State Park in the sand dunes along the Lake Michigan Lakeshore. With increasing temperatures, it is unknown as to how BSC microbial communities will respond and how a changing climate will specifically impact the cyanobacteria within these soils. Therefore, the objective of this research is to isolate cyanobacteria from BSCs of the Indiana Dunes and observe their temperature tolerance in comparison to cyanobacteria from arid deserts of the western US. It is hypothesized that strains from the Indiana Dunes will be more psychrotolerant and respond more similarly to Microcoleus vaginatus from the Colorado Plateau, than Microcoleus steenstrupii from the Sonoran Desert. Two strains of cyanobacteria were isolated from the Indiana Dunes and, following PCR and sequencing, were determined to most likely be strains of Leptolyngbya and Pseudophormidium. These two isolates, M. vaginatus, and M. steenstrupii were allowed to grow for 20 days at 10, 25 and 35oC. Their growth and survival will be determined by changes in the amount of chlorophyll and statistically compared to identify any significant difference in temperature tolerance between these strains. If Leptolyngbya and Pseudophormidium are unable to grow in warmer temperatures then their ability to colonize BSCs may be affected and this will have unknown consequences to the microbial ecosystems they harbor as temperatures increase.http://opus.ipfw.edu/stu_symp2017/1036/thumbnail.jp
Nutritional, Economic, and Environmental Benefits of Wholesome Insects
No full textIt is widely accepted that by 2050 the world will host 9 billion people. Today’s society already copes with nearly 1 billion chronically hungry people worldwide; factoring climate change effects and subsequent alterations in geology, there will be devastating effects on food sources. We need to find new ways of growing food and rediscover our original diets as Homo-sapiens. An insectivorous diet is able to provide essential proteins and nutrients to the human body. Insect consumption also offers a significant opportunity to merge traditional knowledge and modern science in both developed and developing countries. Placing insects back into the human diet will allow alternative nutrition, a healthier environment, and increased trade and economic development. This paper contains two surveys conducted in the hope of raising awareness of the many valuable roles that insects play in sustaining nature and in human life. The first survey, with 100 responses, sheds light on the misperceptions people have when considering eating insects. In the end, 39 of the 100 responses would choose insect diets over beef. The second survey of 200 responses gives the respondents nutritional, environmental, and geographical facts about insects before leading into questions in response to the facts given. Based on the second survey conducted, 88% of 200 respondents are more willing to try insects and believe in the changes that could happen globally if the insect diet were embraced. From the two surveys, it appears people are more willing to try insects after they have been presented with the relevant nutritional and environmental incentives. All it takes is education/ and exposure to change people’s perceptions.http://opus.ipfw.edu/stu_symp2017/1031/thumbnail.jp
Animation of Kevin Gemin
No full text“Revisiting and Reinventing the Technique of Kevin Gemin.” I am presenting a creative project to develop a short animation based on the work of Kevin Gemin, a French animator. The main purpose of this creative project proposal is to understand the animating technique of Kevin Gemin, and how he uses the somewhat unusual program of Flipnote Studio1 for his work. The impact of this technique is defined by its frame-by-frame method, and how the work of this artist can be applied today to Nintendo 3DS, 3D animation and gamin consoles. A fundamental goal of this project is to implement Gemin’s animation technique in the narrative of the short animation sequential process and how this process will help me to craft my own style of storyboarding and concept art. The goals of my project are to: ● Develop a character based on his animations in 2D and 3D, and how he is multifaceted for multiple media: video games, cinematic, and Virtual Reality. ● Study transition effects in the video animations, and how they help to enhance the animation narrative. ● Study and apply Kevin Gemin’s visual effects in his animated sequences and cinematic videos, such as Fade In Fade Out, Blinds, Dissolve, etc. The project will help me expand my knowledge and skill set as an artist and animator. 1 Flipnote Studio allows the user to create both word and picture-based notes with the stylus, add sound, and put them together to create frame-by-frame flipbook-style animations. https://en.wikipedia.org/wiki/Flipnote_Studiohttp://opus.ipfw.edu/stu_symp2017/1012/thumbnail.jp
Revising History: Exploring what Lies Below the Historical Cannon
No full textIn this project, I illustrate the interdisciplinarity of international, intercultural creative writing and history through the construction of my short story, “The Lord of Pandemonium.” I wrote it for my class in Writing Fiction, in which I developed my own writing process based on drafting, research and revision in a multidisciplinary approach. Although multidisciplinarity in storytelling offer refers to the use of multiple media resources (picture, video, audio) which complement the story, my approach explores the steps taken in order to create a story in an existing historical context, honing in from other subject areas in academia but maintaining a single dimension to storytelling in written words. My process includes research of the cultural and international context as well as the process of revision. The research I have done contributed to the composition of the reality in which the story takes place: the period of instability immediately preceding the Rwanda genocide. I went through academic articles and online research of news pieces, which offered accounts and analysis of the genocide. Together, these offered the basic structuring of the world I wrote in. I used the compiled data to construct not only a three-dimensional “map” or “scheme” of the world in which the story takes place, but also a historical context that explains why things were the way they were at a political, cultural and individual level. The second section of my process is based on revision, which prompted me to wonder how I could offer a different account of history. For revision I honed in on Diane Lefer’s essay “Breaking the ‘rules’ of story structure,” in which she argues in favor of the breaking of conventions in writing – how a story can be told in a new way. In other words, “how could I offer a different perspective to read this historical event?” Instead of weighing experiences against facts and trying to balance them out, I decided to expose facts through a narrative. Revision is about trying to get a fresh perspective on the story’s subject, so my story is about the people who do not show up in detail in history books or research. It is not factual in its character-driven plot, but every event that alters the character’s life and experiences is based on fact. Although I make use of history to bring life to the character, in my revision I honed in on individuality. How is an individual impacted by ethnic conflict, post-colonial society and which side does he take? How does that affect his perspective of the world and his personal relationships? As a person, how would this setting change the way a character sees the world? To me, that is a special kind of storytelling because I am focusing on the humanity behind history and on how people’s hands form and destroy their futures. That is what makes storytelling personal, relatable and even educational. Different perspectives, different opinions prompt learning and personal connections. My effort to try to reach for those who have not had their voices heard and trying to learn about an entirely different country is a form of creating and accepting dissent, new voices that contribute to political debate and reach people’s hearts. That public debate, which is essential for a functional democratic society, can be prompted by these revisions. I consider myself better for driving off the beaten path and deviating from our common historical knowledge. I think sharing this process can help other people learn, grow and see beyond the current, established and detached accounts of history and connect to the past in a more human wa
