National Cyber Strategy of the United States of America

Description: With the release of this National Cyber Strategy, the United States now has its first fully articulated cyber strategy in 15 years. This strategy explains how the US will: Defend the homeland by protecting networks, systems, functions, and data; Promote American prosperity by nurturing a secure, thriving digital economy and fostering strong domestic innovation; Preserve peace and security by strengthening the ability of the United States — in concert with allies and partners — to deter and, if necessary, punish those who use cyber tools for malicious purposes; and Expand American influence abroad to extend the key tenets of an open, interoperable, reliable, and secure Internet. The new U.S. cyber strategy seeks to allay some of those concerns by promoting responsible behavior in cyberspace, urging nations to adhere to a set of norms, both through international law and voluntary standards. It also calls for specific measures to harden U.S. government networks from attacks, like the June 2015 intrusion into the U.S. Office of Personnel Management (OPM), which compromised the records of about 4.2 million current and former government employees. And the strategy calls for the U.S. to continue to name and shame bad cyber actors, calling them out publicly for attacks when possible, along with the use of economic sanctions and diplomatic pressure.

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

Description: 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 climate were less likely to be taking action and do not participate in social groups where climate change is discussed. Conclusions are that the whole group would like more and better communication and education from our leaders, that they also expect our leaders to be part of creating solutions to climate change, and that the solutions the interviewees suggested provide a very thorough initial list of mitigation and adaptation strategies for the city's future CAP.

Adventure in the Classroom: Role and Practices of Adventure Therapy in School Counseling Curriculum

Description: The purpose of this study was to explore the role and impact of adventure therapy (AT) on student development and to identify the greatest challenges to the implementation of AT in schools. The Delphi method was used to generate consensus of opinion within a group of experts in the field of adventure therapy and school counseling. Purposive sampling was used to identify the members of the expert panel and the definition of consensus was set at 80% for each item. Content and descriptive analysis were used to develop representative statements from participant responses between rounds. Ten Caucasian respondents, 6 men and 4 women, having met at least one of the expert criteria for the study, completed three rounds of participation which resulted in the attainment of consensus on 36 items addressing the role of adventure therapy in school counseling and the impact of AT in the areas of academic/career and social/emotional development. Twelve challenges to the implementation of AT in schools were identified and put in rank order. According to the results, experts believe adventure therapy has the greatest impact on social connectedness, problem solving, and student engagement in schools. Access to appropriate training in AT, administrative support, and funding were identified as the three greatest challenges to the implementation of adventure therapy in schools.

Analysis of Young and Mature Thrombocytes in Zebrafish

Description: 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 compared to young thrombocytes suggesting the lipid composition may be important for differential labeling. Therefore, we tested the liposomes prepared with different ratios of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) and observed that the lower amounts of PE favor the DiI-C18 labeling whereas higher concentrations of PC are less efficient. Also, in both PE and PC, increased concentrations of both resulted in decreased binding. These results are consistent with our observation that mature thrombocytes have higher concentrations GP and thus DiI-C18 may not bind to them efficiently compared to young thrombocytes.

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

Description: 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.

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

Description: 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 discovery that meditation makes the heartbeat depart from the ideal condition of 1/f noise. We also discussed how to combine the wave-like nature of the dynamics of the brain with the existence of crucial events that are responsible for the 1/f noise. We showed that the anomalous scaling generated by the crucial events could be established by means of a direct analysis of raw data. The efficiency of the direct analysis procedure is made possible by the fact that periodicity and crucial events is the product of a spontaneous process of self-organization. We argue that the results of this study ...

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

Description: 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 not desired.

The Art of Marimba Articulation: A Guide for Composers, Conductors, and Percussionists on the Expressive Capabilities of the Marimba

Description: Articulation is an element of musical performance that affects the attack, sustain, and the decay of each sound. Musical articulation facilitates the degree of clarity between successive notes and it is one of the most important elements of musical expression. Many believe that the expressive capabilities of percussion instruments, when it comes to musical articulation, are limited. Because the characteristic attack for most percussion instruments is sharp and clear, followed by a quick decay, the common misconception is that percussionists have little or no control over articulation. While the ability of percussionists to affect the sustain and decay of a sound is by all accounts limited, the ability of percussionists to change the attack of a sound with different implements is virtually limitless. In addition, where percussion articulation is limited, there are many techniques that allow performers to match articulation with other instruments. Still, percussion articulation is often a topic of little concern to many musicians. The problem is not that this issue has been completely ignored, but rather that a vast number of contradictory and conflicting viewpoints still permeate pedagogical methods and literature. This is most certainly the case with the marimba, where a review of method books reveals a multitude of confusing statements about marimba articulation. It is clear that there is still widespread confusion about marimba articulation from composers, conductors, and most importantly percussionists themselves. This study attempts to advance percussion pedagogy in this area through a better understanding of the terminology of musical articulation, the acoustical principles of the marimba, and the techniques that affect sound production on this instrument. After a review of these three areas, this study examines 166 recordings, which look at the actual effect of specific techniques carried out on the marimba. Finally, the project offers a set of recommendations for composers, ...
