2016 Performance and Accountability Report
The FY 2016 Performance and Accountability Report for the Institute of Museum and Library Services comes as IMLS begins a yearlong celebration marking its 20th Anniversary. In the last 20 years, IMLS has worked to benefit libraries of all types: public, research, academic and tribal; and museums of all disciplines: history, botanic gardens, aquariums, science and technology centers, children’s museums and zoos. With the help of a range of partners, IMLS has inspired libraries and museums to advance innovation, learning and civic engagement. That work will continue into the coming years as libraries and museums are urged abd encouraged to “Reimagine the Future” and how they can best serve the communities in which they reside. Those goals are reflected in this year’s report: to continue to focus on creating a nation of learners by preserving and providing broad public access to collections and content; and promoting policies that ensure robust library, museum, and information services for all Americans. IMLS continues to be an outstanding steward of federal funds and will continue to look for ways to achieve even greater impact on library and museum services throughout the United States.

2D and 3D Fabrication Devices: Can They Improve Spatial Reasoning Skills in Children?
The purpose of this study is to evaluate the potential benefit of two hours of activities involving 2D and 3D fabricators on the spatial reasoning skills of children in Grades 4 and 5, ages 9 to 10, from a private school in Southeast Texas. Can the introduction to hands-on activities with products created with these devices and learning about how these devices operate improve spatial reasoning skills? The research also evaluates the use of the Shapes Test as a valid measure of the spatial reasoning skills of children. The Cube Design and Spatial Memory subtests of the UNIT (Universal Nonverbal Intelligence Tests) were used for evaluating the spatial reasoning skills of the participants, based on their respected validity, along with a Shapes Test that is in development. Discussion regarding gender, language, and experiential theories of spatial reasoning skill development are included in the literature review.

Academic Progress Scores to Predict Performance on a State Assessment
This quantitative study examined seventh-grade reading scores to determine the extent to which certain demographic variables (race/ethnicity, gender, socioeconomic status) explain and MAP reading scores predict reading scores on the State of Texas Assessment of Academic Readiness (STAAR) in a selected northeast Texas public school. Standardized assessments only compare the relative performance of an individual student to other groups of students using scaled scores, which can vary from year to year and from state to state. With the advent of computer adaptive testing, this study provides information on the predictive validity of benchmark assessments. Specifically, this study looked for predictive evidence that indicates how accurately test data can predict criterion scores. Findings revealed, through a multiple regression analysis, that the fall MAP Rasch Unit (RIT) scores predicted the STAAR scale scores. Using SPSS version 22, the data were entered and analyzed in a multiple regression model to determine the presence of a statistical trend or lack thereof. Demographic data and MAP scores were entered into the regression model to examine the predictive validity of the MAP assessment in determining student performance on the STAAR seventh-grade state-mandated reading assessment. The statistical analysis revealed that MAP RIT scores explain a significant variance …

Accelerated Corrosion Test with Operation Simulation of All-Aluminum Microchannel Heat Exchangers
The HVAC&R industry is looking to transition from copper-aluminum heat exchangers to all-aluminum microchannel technology. The want for the transition stemmed from seeing the performance improvement of all-aluminum microchannel radiators in the automotive industry. Applications differ between the two industries; therefore, applying this technology for HVAC&R use must be validated. Research towards operating modes of an all-aluminum heat exchanger in a defined corrosive environment will provide the industry with a better understanding of heat exchanger design and heat exchanger material selection. The worth in this is preventing overdesign and producing more efficient heat exchangers. Furthermore, ASHRAE members and the corrosion community will find value in a defined corrosion system and corrosion test procedure. The information gained through past research has progressed assessment of material performance; however, the methods improperly simulate and expedite natural weathering. The most common method being used is the ASTM (American Society of Testing Materials) Sea Water Acetic Acid Test. The research discussed in this paper was focused on improving a standard corrosion system by implementing system modifications to simulate heat exchanger operation while performing a modified wet-dry cyclic test (e.g. ASTM G85 Annex 5). The goal is to produce results that are more representative of natural …

Accelerated Degree Program Faculty: Motivation to Teach
Adult educators are a growing part of American higher education. Because of their increasing prominence in adult education, it is essential to understand what roles these educators play and what motivates them to remain in the profession despite poor work prospects and conditions. Research to date, however, focuses primarily on the adult learner and not the adult educator. The purpose of this qualitative, multiple-case study was to explore the role and motivation for teaching of adult educators employed as adjunct faculty in an accelerated degree program at a small, liberal arts college in the northwest United States. Purposeful sampling was used to select the five participants for the study. All participants taught in the program for more than five years and were considered to be successful in their positions by peers, students, and administrators. The study employed a preliminary demographic survey to solicit initial background data on the instructors. Other data collection included in-depth, open-ended, face-to-face interviews, document analysis, and classroom observation. The results showed that all five participants identified the following roles and assumed them in the classroom: (a) facilitator, (b) listener, (c) specialist, (d) guide, (e) adviser, and (f) co-learner or colleague. Further results showed that all five …

Acceptability of Behavioral Interventions for Autism
Caregivers' evaluation of evidence-based behavioral interventions may differ dependent upon the type of language used to describe the intervention. We administered a survey to 24 parents of children with autism to assess social validity measures of behavioral interventions described in one of three communication styles: technical, conversational, and conversational with intended outcome. Participants were presented with a description of two behavior-reduction and two behavior-acquisition interventions. Overall, interventions described in conversational with intended outcome style received the highest social validity ratings, while interventions described in the technical style received the lowest ratings. Moreover, behavior-acquisition interventions were rated significantly higher than behavior-reduction interventions when described in either conversational or conversational with intended outcome style. The current study supports the requirements of the Behavior Analyst Certification Board's Compliance Code that behavior analysts should inform the client/consumer of the treatment/interventions in an understandable language. Findings are also discussed in terms of verbal communities.

Accuracy of Partner Perception and Relationship Satisfaction: Investigating Masturbatory Habits
An individual's perceptions of various aspects of one's romantic relationship (irrespective of whether or not the perceptions align with reality) often play a critical role in romantic relationship satisfaction. Research has demonstrated that the accuracy of an individual's perception of his or her partner is generally positively related to the individual's romantic relationship satisfaction. However, when perceiving negative or conflictual messages from a partner, an individual's accuracy of perception is negatively associated with his or her romantic relationship satisfaction. Researchers have suggested that poor accuracy in perceiving negative messages might diffuse the negative intention in a way that is less impactful to the relationship. The present study was designed to investigate accuracy in the perception of sexual topics, specifically masturbatory habits. A sample of 93 married couples (186 individuals) responded to questions about (a) their own masturbatory behaviors and (b) their perception of their partners' masturbatory behaviors to determine the accuracy of each partner's perception of his or her partner. The association between accuracy and romantic and sexual relationship satisfaction was explored, along with one potential moderating variable: attitudes toward masturbation. Perceived reason for masturbating, perceived target of arousal during masturbation, and partner's actual reason for masturbating all positively predicted …

Achieving Financial Sustainability: Are We Asking the Wrong Questions?
While technology has made producing copies of digital content almost entirely free, there is no escaping that publishing, according to most definitions of the term, still requires time and money. Any publishing service offered by a library must find a way to achieve financial sustainability—that is, operate without losing money. However, even "losing money" is a tricky concept, especially when taking into account varying definitions of operating expenses (overhead costs) under different models for auxiliary services. Libraries are by their very nature cost centers, providing services without the expectation of recovering revenue, and are usually part of larger organizations that similarly provide services under partial or full subsidies. While libraries are often comfortable with charging for convenience services and for services to those outside their designed community of users, careful thought should be given to which costs a publishing service-or any new service-should be expected to recover.

Addressing Social Elements of Wildfire: Risk, Response, and Recovery in Highland Village, TX
Representatives of the City of Highland Village expressed concern over the risk of wildfires for their community. Anthropology provides many tools for and examples of disaster assessment of preparedness, response, recovery, and mitigation. These tools combined with Geographic Information Systems (GIS) can provide a holistic, cultural ecological look at how such a disaster may take place in the city. The project's methods included a detailed survey of preparedness steps which was analyzed using SPSS and also imported into ArcGIS for spatial analysis, and semi-formal, in-depth interviews with residents of the community regarding preparedness, response, and recovery. Residents fell into a middle category of preparedness, with the majority of participants considering or implementing a few recommended preparedness steps. Interview participants expressed respect for and trust of the city and first-responders, as well as a willingness to volunteer their help during response and recovery stages. Finally the American Community Survey showed that resident socioeconomic vulnerability was considerably low, and no action needed to be taken to advocate for at-risk individuals. Overall, the City of Highland Village showed a high resiliency to disaster. A wildfire likely will not have a major impact on the community as a whole, though the city may reduce …

Adhesion and Surface Energy Profiles of Large-area Atomic Layers of Two-dimensional MoS2 on Rigid Substrates by Facile Methods
Two-dimensional (2D) transition metal dichalcogenides (TMDs) show great potential for the future electronics, optoelectronics and energy applications. But, the studies unveiling their interactions with the host substrates are sparse and limits their practical use for real device applications. We report the facile nano-scratch method to determine the adhesion energy of the wafer scale MoS2 atomic layers attached to the SiO2/Si and sapphire substrates. The practical adhesion energy of monolayer MoS2 on the SiO2/Si substrate is 7.78 J/m2. The practical adhesion energy was found to be an increasing function of the MoS2 thickness. Unlike SiO2/Si substrates, MoS2 films grown on the sapphire possess higher bonding energy, which is attributed to the defect-free growth and less number of grain boundaries, as well as less stress and strain stored at the interface owing to the similarity of Thermal Expansion Coefficient (TEC) between MoS2 films and sapphire substrate. Furthermore, we calculated the surface free energy of 2D MoS2 by the facile contact angle measurements and Neumann model fitting. A surface free energy ~85.3 mJ/m2 in few layers thick MoS2 manifests the hydrophilic nature of 2D MoS2. The high surface energy of MoS2 helps explain the good bonding strength at MoS2/substrate interface. This simple adhesion …

Adolescent's Social Networking Use and Its Relationship to Attachment and Mental Health
Adolescents spend much of their time using the internet and electronic media. Since its inception, the use of online social networking (OSN) sites by adolescents continues to grow. With the proliferation of OSN, it is critical to examine how this activity affects psychological development, but better measurement tools are needed. As researchers struggle to keep up with this rapidly growing field, many gaps remain in the literature investigating the interrelations between adolescent's OSN use and mental health outcomes. Research examining the relationship between OSN and mental health outcomes, specifically depression and anxiety, has produced mixed results suggesting that other factors influence this association. A large research literature documents associations between attachment and mental health. Given that attachment also affects interpersonal communication, several studies have investigated links between attachment and OSN use in adult and college populations. Results indicated that even though attachment to father was independently related to anxiety and depression symptoms, it was not a significant moderator for mental health and OSN. Attachment to mother was a significant moderator for anxiety and depression and several OSN subscales. Based on this information, a greater focus on youth's interpersonal connection and social skills both online and offline may be beneficial when …

The Adoption, Management, and Performance of Local Government Investment Pools: A Comparative Analysis of State Practices
This dissertation examines the factors influencing a state’s decision to adopt a local government investment pool (LGIP), the institutional arrangements used in managing them, and the effect of the institutional types on LGIP performance. The dissertation extends the policy adoption theory with insights from investment theory to demonstrate that management credibility influences the likelihood of a state’s LGIP adoption. The study finds that the quality of financial management, the quality of professional leadership, proximate state neighbors who have previously adopted an LGIP, and economic factors determine a state’s proclivity to policy adoption. The dissertation also describes the institutional arrangements used in managing LGIPs and develops typologies based on their institutional arrangements. The dissertation compares LGIPs depending on the risk aversion of their institutional arrangements. The research extends the risk-return tradeoff in investment theory to LGIP institutional arrangements. The empirical findings show that LGIP institutional arrangement that has greater risk report higher performance. The dissertation also finds that competition in the LGIP market due to multiple vendors, and periods of economic recession account for higher performance because of higher risk-taking behaviors associated with them. This dissertation promotes public funds investment laws that emphasize prudent management of government finances and guides managers …

Aging Texas Well: An Assessment of Denton's Aging-Friendliness
The purpose of this research was to conduct a needs assessment for the city of Denton, Texas to learn how residents view Denton's aging-friendliness. The research design was based on the Texas Department of Aging and Disability Services' Aging Texas Well Toolkit and was funded by a two year grant from that agency. Both qualitative and quantitative methods were used to gather data on six community indicators: demographics, housing, transportation, health care (including mental health and substance abuse services), recreation, and community supports and services. Input from city residents was gathered through focus groups, followed by a survey of the broader community in the city to validate and prioritize the needs identified. The research found gaps in Denton's aging-friendliness. Denton residents feel that although there are some services for the aging in the area, other services are lacking. The top needs identified by residents were a single point of contact for, and better communication about, resources currently available, as well as a need for increased transportation options.

AirSniffer: A Smartphone-Based Sensor Module for Personal Micro-Climate Monitoring
Environmental factors can have a significant impact on an individual's health and well-being, and a primary characteristic of environments is air quality. Air sensing equipment is available to the public, but it is often expensive,stationary, or unusable for persons without technical expertise. The goal of this project is to develop an inexpensive and portable sensor module for public use. The system is capable of measuring temperature in Celsius and Fahrenheit, heat index, relative humidity, and carbon dioxide concentration. The sensor module, referred to as the "sniffer," consists of a printed circuit board that interconnects a carbon dioxide sensor, a temperature/humidity sensor, an Arduino microcontroller, and a Bluetooth module. The sniffer is small enough to be worn as a pendant or a belt attachment, and it is rugged enough to consistently collect and transmit data to a user's smartphone throughout their workday. The accompanying smartphone app uses Bluetooth and GPS hardware to collect data and affix samples with a time stamp and GPS coordinates. The accumulated sensor data is saved to a file on the user's phone, which is then examined on a standard computer.

Am I Crazy or Spiritually Transforming? Beyond the Differentiation of Psychiatric and Spiritually Transformative Experiences
Abstract: Spiritually transformative experiences (STEs) may sometimes present with the symptomatology of psychiatric disorders. Transformational crisis may even occur within the context of a psychiatric hospitalization. Such STEs are at odds with the medical model of Western psychiatry that emphasizes pathology. Yet a coherent approach yields no absolute differentiation between spiritual emergence and what health professionals diagnose as mental illness. A historical perspective begins with the presumed differentiation between authentic spiritual experience and psychiatric illness. A more functional approach to spiritual emergency takes into account the perspective of experiencers, their communication and meta-communication skills, and the integration process itself. One case from the popular literature and two cases from the author's psychotherapy practice are presented to demonstrate that the list of causative experiences for STEs can include what is diagnosable as a psychiatric condition, specifically, bipolar disorder.

Analysis and Optimization of Graphene FET based Nanoelectronic Integrated Circuits
Like cell to the human body, transistors are the basic building blocks of any electronics circuits. Silicon has been the industries obvious choice for making transistors. Transistors with large size occupy large chip area, consume lots of power and the number of functionalities will be limited due to area constraints. Thus to make the devices smaller, smarter and faster, the transistors are aggressively scaled down in each generation. Moore's law states that the transistors count in any electronic circuits doubles every 18 months. Following this Moore's law, the transistor has already been scaled down to 14 nm. However there are limitations to how much further these transistors can be scaled down. Particularly below 10 nm, these silicon based transistors hit the fundamental limits like loss of gate control, high leakage and various other short channel effects. Thus it is not possible to favor the silicon transistors for future electronics applications. As a result, the research has shifted to new device concepts and device materials alternative to silicon. Carbon is the next abundant element found in the Earth and one of such carbon based nanomaterial is graphene. Graphene when extracted from Graphite, the same material used as the lid in pencil, …

Analysis of Factors for Successful State-Level Support of Low-Performing Schools
This study provides a qualitative look at Texas' Professional Service Providers' (PSPs) strategies for supporting low-performing schools. Four PSPs were selected for participation based on the number of schools they helped exit the Texas Title I School Improvement Program from 2007-2012. Data collected and analyzed included provider and principal interviews, providers' progress reports documenting services, and principals' evaluations of provider services. Results indicated key support strategies in two of four cases were supporting and mentoring/coaching while communicating and building trust were important in the other two cases. Communicating, reviewing information, and planning were important across all cases. The quality indicators aligning with the PSPs' strategies were fit, comprehensiveness, and coherence. They were also the most common across all cases. Finally, analysis of the evaluation of provider services revealed PSP-1 with the highest ratings, followed by PSP-2, PSP-3, and PSP-4 respectively. The findings suggest, first, that PSP support has a dual nature. Contextual support was provided based on the campus leaderships' skills and requests. PSPs also ensured coherence among the strategies of all stakeholders. Secondly, a hierarchy of quality service indicators aligned to the PSPs' strategies: fit, comprehensiveness, and coherence. Finally relationships are vital to a successful provider-campus relationship. The findings …
