17 USC 109: The First Sale Doctrine

This document is part of a series of white papers on various copyright issues. One statute, 17 USC § 109, provides a number of exceptions specifically for libraries. In addition to fair use, there are a variety of other exceptions built into the copyright law that don’t get as much attention.This paper argues that as there is no digital first sale, libraries can continue to use 17 USC ​§ ​109 for physical collections and are safe to lend the books they own without worrying about copyright problems.

Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America (open access)

Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America

The aging experience of men and women in rural America is different than that of their urban counterparts. In this study, I identified key disparities in access to health care, mortality, and utilization of health care that result from geographic location. Foundational theories are discussed to illustrate that disparities can originate from historical societal behaviors. Secondary data and literary reviews create a combined qualitative and quantitative approach to explore the rural/urban divide, concluding that the potential for increased disparities as the aging population grows is very real and rural residents remain vulnerable to a poor(er) aging experience. Recommendations for policy and practice, as well as additional research, are made to address the conclusion.

Accurate Joint Detection from Depth Videos towards Pose Analysis (open access)

Accurate Joint Detection from Depth Videos towards Pose Analysis

Joint detection is vital for characterizing human pose and serves as a foundation for a wide range of computer vision applications such as physical training, health care, entertainment. This dissertation proposed two methods to detect joints in the human body for pose analysis. The first method detects joints by combining body model and automatic feature points detection together. The human body model maps the detected extreme points to the corresponding body parts of the model and detects the position of implicit joints. The dominant joints are detected after implicit joints and extreme points are located by a shortest path based methods. The main contribution of this work is a hybrid framework to detect joints on the human body to achieve robustness to different body shapes or proportions, pose variations and occlusions. Another contribution of this work is the idea of using geodesic features of the human body to build a model for guiding the human pose detection and estimation. The second proposed method detects joints by segmenting human body into parts first and then detect joints by making the detection algorithm focusing on each limb. The advantage of applying body part segmentation first is that the body segmentation method narrows …

Adolescent Academic Adjustment during Chronic Illness: Online Training for Child Life Specialists (open access)

Adolescent Academic Adjustment during Chronic Illness: Online Training for Child Life Specialists

Frequent absences resulting from a chronic illness can disrupt adolescent school involvement, impacting academic achievement and psychosocial development as a result. This study explores whether certified child life specialists (CCLSs) could be a resource for parents as they address their adolescents' academic disruptions. Specifically, this study assesses an online training program designed to increase CCLSs' knowledge and self-efficacy as related to adolescents' academic adjustment following frequent absences. This knowledge and skill based training was designed as a three part module with sections including: academic considerations, psychosocial considerations, and availability of school resources in promoting successful adolescent academic adjustment. 62 CCLSs were recruited to participate and complete measures evaluating knowledge, in relation to content included in each module, and self-efficacy, involving communication with parents in regards to adolescent academic adjustment. T-tests were conducted to determine whether there were differences in reports of self-efficacy and knowledge following participation in the intervention between and within the treatment and control groups. Results indicate statistical significance for enhanced knowledge and self-efficacy for the treatment group at post-test. Therefore, the outcomes from this study support the effectiveness of brief online training in fostering knowledge and feelings of efficacy for CCLSs in a context not typically included …

Advancing a Community's Conversations About and Engagement with Climate Change (open access)

Advancing a Community's Conversations About and Engagement with Climate Change

The goal of this project completed for the Greater Northfield Sustainability Collaborative (GNSC) was to understand how Northfield, Minnesota citizens are experiencing climate change. Thirty individuals were interviewed to find out what they know about climate change, what actions they are taking, what they think the solutions are to the problems, and what barriers they have to more fully engaging with climate change issues. The interview results are intended to promote and advance the community's discussion on climate change via social learning and community engagement activities such as town hall forums and community surveys. These activities encourage citizens in the community to have direct input into the development of the community's climate action plan (CAP). Analysis of the interviews showed that the interviewees are witnessing climate change, that most are taking at least some action such as recycling or lowering thermostats, that they can name barriers to their own inaction, that they say communication about climate change remains confusing and is not widespread in Northfield, and that they are able to provide numerous suggestions for what the local and broader leadership should be doing. The analysis also showed wide individual variation within the group. Interviewees who were less knowledgeable about …

Allowing Students to Have VOICES (Voluntary Options in Chemical Education Schedules) in General Chemistry I

The purpose of this investigation (a quasi-experimental design called a non-equivalent design group (NEDG)) was to determine if allowing students in a science majors general Chemistry I course the choice in establishing the due dates that their homework was due to the instructor would improve course averages. This study covered two semesters with a total of 288 students participating with n = 158 in the fall and n = 130 in the spring. The students self-selected the homework group, VOICES, that best fit his/her needs which included (1) the instructor's homework schedule, (2) a student-customized schedule or a schedule that followed the exam schedule, or (3) all homework due by the last class day prior to the final exam. Online homework was assigned and graded with individual assignment and homework average grades collected and analyzed. No statistically significant differences were found among the VOICES groups with respect to final course average. Other results of this study replicated findings in the literature; namely, that there is a higher correlation between mathematics skills and course success. Course averages of students who had completed Calculus I or higher were statistically significantly higher than students with less completed mathematics coursework in all VOICES groups. …

Alloy Development and High-Energy X-Ray Diffraction Studies of NiTiZr and NiTiHf High Temperature Shape Memory Alloys (open access)

Alloy Development and High-Energy X-Ray Diffraction Studies of NiTiZr and NiTiHf High Temperature Shape Memory Alloys

NiTi-based shape memory alloys (SMAs) offer a good combination of high-strength, ductility, corrosion resistance, and biocompatibility that has served them well and attracted the attention of many researchers and industries. The alloys unique thermo-mechanical ability to recover their initial shape after relatively large deformations by heating or upon unloading due to a characteristic reversible phase transformation makes them useful as damping devices, solid state actuators, couplings, etc. However, there is a need to increase the temperature of the characteristic phase transformation above 150 °C, especially in the aerospace industry where high temperatures are often seen. Prior researchers have shown that adding ternary elements (Pt, Pd, Au, Hf and Zr) to NiTi can increase transformation temperatures but most of these additions are extremely expensive, creating a need to produce cost-effective high temperature shape memory alloys (HTSMAs). Thus, the main objective of this research is to examine the relatively unstudied NiTiZr system for the ability to produce a cost effective and formable HTSMA. Transformation temperatures, precipitation paths, processability, and high-temperature oxidation are examined, specifically using high energy X-ray Diffraction (XRD) measurements, in NiTi-20 at.% Zr. This is followed by an in situ XRD study of the phase growth kinetics of the favorable …

Analysis of Mature and Young Thrombocytes in Zebrafish (open access)

Analysis of Mature and Young Thrombocytes in Zebrafish

Eukaryotic platelets are small cell fragments that are released into the bloodstream from megakaryocytes, and their production is initiated in the bone marrow. They are mainly involved in blood hemostasis and thrombus formation. The newly synthesized platelets are called reticulated platelets or young platelets. Zebrafish thrombocytes are equivalent to mammalian platelets and have similar characteristics and functions. Likewise, zebrafish has both young and mature thrombocytes. Only young thrombocytes as reticulated platelets are labeled with thiazole orange. Similarly, labeling zebrafish thrombocytes with a specific concentration of DiI-C18 showed two populations of thrombocytes (DiI+ and DiI-). Again, only young thrombocytes showed DiI+ labeling. The mechanism of selective labeling of young thrombocytes by is unknown. Furthermore, there is no zebrafish line where young and mature thrombocytes are differentially labeled with fluorescence proteins. Therefore, in this study, we identified and confirmed that the RFP labeled cells of Glofish were young thrombocytes. In addition, we found that myosin light chain 2 (MLC2) promoter is expressed in young thrombocytes. We also generated a transgenic zebrafish line, GloFli fish, where the young and mature thrombocytes are labeled with red and green fluorescence proteins respectively. Furthermore, this study showed a two-fold increase in glycerol-phospholipids (GP) in mature thrombocytes …

Analyzing Tradeoffs between Privacy Concerns and Active Social Media Presence of 18- to 30-Year-Old College Students (open access)

Analyzing Tradeoffs between Privacy Concerns and Active Social Media Presence of 18- to 30-Year-Old College Students

This study applied the impression management theory in the context of social networking to investigate the generalized research question of this dissertation which is "Do active social media presence and various privacy concerns influence online behaviors of students on social media?" The results and conclusions are presented via the conduct of three different studies and the summary provides insights and explain the overall contribution of the research. For each study we developed a research model for which data was collected separately for each of these models. Hypotheses of each model were tested by partial least squares- structural equation modeling techniques using SmartPLS 2.0. Our findings confirm the hypotheses and showed that all the predictors positively influence online social networking behaviors. Active social media presence is operationalized as predictors such as SNS stalking awareness, Selective disclosure, desired differential persona, impression motivation, and information trustworthiness. Privacy concerns have been operationalized as SNS privacy awareness, technology awareness. Online behaviors have been operationalized as responsible image and reckless image.

Animal Rights and Human Responsibilities: Towards a Relational Capabilities Approach in Animal Ethics (open access)

Animal Rights and Human Responsibilities: Towards a Relational Capabilities Approach in Animal Ethics

In this thesis, I analyze some of the most important contributions concerning the inclusion of animals in the moral and political sphere. Moving from these positions, I suggest that a meaningful consideration of animals' sentience demands a profound, radical political theory which considers animals as moral patients endowed with specific capabilities whose actualization needs to be allowed and/or promoted. Such theory would take human-animal different types of relationships into account to decide what kind of ethical and political responsibilities humans have towards animals. It would be also based on the assumption that animals' sentience is the necessary and sufficient feature for assigning moral status. I start from the consideration that in the history of political philosophy, most theorists have excluded animals from the realm of justice. I then propose an examination of utilitarianism, capabilities approach, and relational-based theories of animal rights (in particular the works by Kymlicka and Donaldson, and Clare Palmer) and borrow essential elements from each of these approaches to build my theory. I claim that a political theory which attaches high importance to individual capabilities, as well as to the various types of relationships we have with animals, is the most appropriate to tackle the puzzle of …

Anthropology of Aging: Assessment of Old Age Needs and Ethical Issues regarding the Use of Assistive Technologies

The main goal of this research has been to investigate elderly people's needs, perceptions, fears, hopes, and expectation regarding elderly care, including ethical issues linked to assistive technologies. As faith seems to take an important place in how some elders face the aging process, the spiritual dimension was also included. Therefore, the research was conducted among 15 church congregants. Results show that most respondents fear the physical and mental decay due to aging, often resulting in becoming a burden to someone else, along with abandonment and lack of financial resources. Most ethnic groups perceive that other cultures take better care of their elders than their own. Faith seems to offer a great support, as it gives the confidence that divine power will always be there for them even beyond death. The respondents in this research suggest that guidance should be provided in a more structured way, more focus should go on the youth and the elderly, more activities should be organized and practical information should be shared. Regarding the ethical issues of assistive technologies, they are not well informed about their possibilities but acknowledge their potential usefulness, combined with human care. They don't want technology to be too intrusive in …

Application of Statistical Physics in Human Physiology: Heart-Brain Dynamics (open access)

Application of Statistical Physics in Human Physiology: Heart-Brain Dynamics

This dissertation is devoted to study of complex systems in human physiology particularly heartbeats and brain dynamics. We have studied the dynamics of heartbeats that has been a subject of investigation of two independent groups. The first group emphasized the multifractal nature of the heartbeat dynamics of healthy subjects, whereas the second group had established a close connection between healthy subjects and the occurrence of crucial events. We have analyzed the same set of data and established that in fact the heartbeats are characterized by the occurrence of crucial and Poisson events. An increase in the percentage of crucial events makes the multifractal spectrum broader, thereby bridging the results of the former group with the results of the latter group. The crucial events are characterized by a power index that signals the occurrence of 1/f noise for complex systems in the best physiological condition. These results led us to focus our analysis on the statistical properties of crucial events. We have adopted the same statistical analysis to study the statistical properties of the heartbeat dynamics of subjects practicing meditation. The heartbeats of people doing meditation are known to produce coherent fluctuations. In addition to this effect, we made the surprising …

Applications of Metallic Clusters and Nanoparticles via Soft Landing Ion Mobility, from Reduced to Ambient Pressures

Nanoparticles, simple yet groundbreaking objects have led to the discovery of invaluable information due to their physiological, chemical, and physical properties, have become a hot topic in various fields of study including but not limited to chemistry, biology, and physics. In the work presented here, demonstrations of various applications of chemical free nanoparticles are explored, from the determination of a non-invasive method for the study of the exposome via using soft-landing ion mobility (SLIM) deposited nanoparticles as a matrix-assisted laser desorption/ionization (MALDI-MS) matrix replacement, to the direct SLIM-exposure of nanoparticles onto living organisms. While there is plenty of published work in soft-landing at operating pressures of 1 Torr, the work presented here shows how this technology can be operated at the less common ambient pressure. The ease of construction of this instrument allows for various modifications to be performed for a wide array of applications, furthermore the flexibility in metallic sample, operating pressure, and deposition time only open doors to many other future applications. The work presented will also show that our ambient SLIM system is also able to be operated for toxicological studies, as the operation at ambient pressure opens the door to new applications where vacuum conditions are …
