Cache-Enabled In Cooperative Cognitive Radio Networks For Transmission Performance, Jiachen Yang, Houbing Song, Chaofan Ma, Jiabao Man, Huifang Xu, Gan Zheng

Publications

The proliferation of mobile devices that support the acceleration of data services (especially smartphones) has resulted in a dramatic increase in mobile traffic. Mobile data also increased exponentially, already exceeding the throughput of the backhaul. To improve spectrum utilization and increase mobile network traffic, in combination with content caching, we study the cooperation between primary and secondary networks via content caching. We consider that the secondary base station assists the primary user by pre-caching some popular primary contents. Thus, the secondary base station can obtain more licensed bandwidth to serve its own user. We mainly focus on the time delay …

Advances In Plant-Derived Scaffold Proteins, Congyue Annie Peng, Lukasz Kozubowski, William R. Marcotte Jr.

Publications

Scaffold proteins form critical biomatrices that support cell adhesion and proliferation for regenerative medicine and drug screening. The increasing demand for such applications urges solutions for cost effective and sustainable supplies of hypoallergenic and biocompatible scaffold proteins. Here, we summarize recent efforts in obtaining plant-derived biosynthetic spider silk analogue and the extracellular matrix protein, collagen. Both proteins are composed of a large number of tandem block repeats, which makes production in bacterial hosts challenging. Furthermore, post-translational modification of collagen is essential for its function which requires co-transformation of multiple copies of human prolyl 4-hydroxylase. We discuss our perspectives on how …

Color-Based Template Selection For Detection Of Gastric Abnormalities In Video Endoscopy, Hussam Ali, Muhammad Sharif, Mussarat Yasmin, Mubashir Husain Rehmani

Publications

Computer-aided diagnosis of gastric diseases from endoscopy frames is an important task. It facilitates both the patient and gastroenterologist in terms of time, money and most important health. Colors are the basic visual features of endoscopic images and also provide clues about abnormal regions in endoscopy frames. A variety of color spaces available for representation of color frames. However, we are not certain about which color space is more suitable for representing color features of gastric images. This paper presents a comparison of color features in different color spaces for detection of abnormal areas in chromoendoscopy (CH) frames. In addition, …

Sleep And Organizational Behavior: Implications For Workplace Productivity And Safety, June J. Pilcher, Drew M. Morris

Publications

The interaction between sleep and work-related behaviors influence many aspects of employee performance, safety, and health as well as organizational-level success. Although it is well established that quantity and quality of sleep can affect different types of task performance and personal health, the interactions between sleep habits and organizational behaviors have received much less attention. It is important to examine how sleep habits and workplace behaviors relate and the role of the underlying circadian rhythm on the potential impact of sleep and sleepiness in the workplace. Developing a deeper understanding of how sleep habits and sleepiness impact workers and the …

Complete Plastid Genome Sequences Of Two Species Of The Neotropical Genus Brunellia (Brunelliaceae), Janice Valencia Duarte, José Murillo-A, Clara Inés Orozco, Carlos Parra-O, Kurt M. Neubig

Publications

Here we present the first two complete plastid genomes for Brunelliaceae, a Neotropical family with a single genus, Brunellia. We surveyed the entire plastid genome in order to find variable cpDNA regions for further phylogenetic analyses across the family. We sampled morphologically different species, B. antioquensis and B. trianae, and found that the plastid genomes are 157,685 and 157,775 bp in length and display the typical quadripartite structure found in angiosperms. Despite the clear morphological distinction between both species, the molecular data show a very low level of divergence. The amount of nucleotide substitutions per site is one of the …

Establishing Content Validity For A Conceptualized Instrument To Measure Barriers To Eating A Healthful Diet In Adults: A Consensus Approach, Enia Zigbuo-Wenzler, Gayenell S. Magwood Phd, Rn, Faha, Faan, Martina Mueller, Angela Fraser

Publications

BACKGROUND: A poor quality diet is a well-known risk factor for many chronic diseases. However, eating a healthful diet is not always simple as many underlying factors can impede adherence. Individuals with fewer barriers are more likely to eat a healthful diet than those who have more barriers. Accurately measuring barriers to eating a healthful diet could inform personalized interventions, particularly those aiming to prevent chronic diseases. The aim of this study was to establish content validity for selected items obtained from the National Health and Nutrition Examination Survey (NHANES) database to be considered for inclusion as items on the …

Developing A Taxonomy For Success In Commercial Pilot Behaviors, Kristine Kiernan, David S. Cross, Mark Scharf Ph.D.

Publications

Human error has been well studied in aviation. However, less is known about the ways in which human performance maintains and contributes to aviation safety. The lack of data on positive human performance prevents consideration of the full range of human behaviors when making safety and risk management decisions. The concept of resilient performance provides a framework to understand and classify positive human behaviors. Through interviews with commercial airline pilots, this study examined routine airline operations to evaluate the concept of resilient performance and to develop a taxonomy for success. The four enablers of resilient performance, anticipation, learning, responding, and …

Indicators Per Factor In Confirmatory Factor Analysis: More Is Not Always Better, Jennifer Koran

Publications

Although some research in confirmatory factor analysis has suggested that more indicators per factor is generally better, studies have also documented that sample size requirements increase as model size increases. The present study used Monte Carlo simulation to investigate the effect of indicators per factor on sample size requirements. Results demonstrated a nonlinear association between the number of indicators per factor and the minimum required sample size while avoiding six important consequences for the analysis, such as bias in the model chi-square statistic. There is an upper limit for the desirable number of indicators per factor, and this upper limit …

Teamwork Makes The Dream Work: Using Team-Based Learning In The Science Classroom, Virginia J. Moore, Elizabeth Mitchell Prewitt, Amber Jean Carpenter-Mccullough, Brooke A. Whitworth

Publications

With an overwhelming amount of research and a demand for collaborative learning in the classroom, teachers are tackling challenges at all educational levels that often accompany the social aspects of group work. Team-Based Learning (TBL) is an instructional sequence that shifts instruction from teacher lecture to small-group learning. Through the use of teams and social learning, students are actively engaged and learning through critical-thinking tasks. College students can take responsibility both for their own learning and for each other as learners and fellow human beings. TBL allows the instructors to design opportunities for students to demonstrate what they know and …

Do We Need More Productive Theorizing? A Commentary, David Reinking, David B. Yaden Jr.

Publications

In this commentary, we argue that literacy research would be more produc- tive if researchers had a clearer, more nuanced understanding of theory. Specifically, we argue that theory in a practice-oriented field is most fun- damentally productive when it provides instrumental guidance for literacy beyond academic understanding about literacy. Premises for that argument are presented, as well as how productivity connects to an instrumental view of theory within the philosophy of science. We provide examples from au- thoritative sources and relevant studies suggesting that conceptions and uses of theory in literacy research are ambiguous, diffuse, and incoherent. We argue that …

The Effect Of Professional Development On Elementary Science Teachers’ Understanding, Confidence, And Classroom Implementation Of Reform‐Based Science Instruction, Jennifer L. Maeng, Brooke A. Whitworth, Randy L. Bell, Donna R. Sterling

Publications

Through a randomized controlled trial, this mixed‐methods study evaluated changes in elementary science teachers’ understandings, confidence, and classroom implementation of problem‐based learning (PBL), inquiry, and nature of science (NOS) instruction following participation in a professional development (PD) as well as the components of the PD that teachers perceived facilitated these changes. Results indicated that following the PD, treatment teacher (n = 139) understandings of and confidence for teaching inquiry, NOS, and PBL were significantly greater than control teachers (n = 98) after controlling for preunderstandings and confidence. The effect sizes were large. Treatment teachers also incorporated significantly more …

The Effect Of Health Insurance On Crime: Evidence From The Affordable Care Act Medicaid Expansion, Qiwei He, Scott Barkowski

Publications

Little evidence exists on the effect of the Affordable Care Act (ACA) on criminal behavior, a gap in the literature that this paper seeks to address. Using a simple model, we argue we should anticipate a decrease in time devoted to criminal activities in response to the expansion, because the availability of the ACA Medicaid coverage raises the opportunity cost of crime. This prediction is particularly relevant for the ACA expansion because it primarily affects childless adults, a population likely to contain individuals who engage in criminal behavior. We validate this forecast empirically using a difference‐in‐differences framework, estimating the expansion's …

White-Handed Gibbons Discriminate Context-Specific Song Compositions., Julie Andrieu, Samuel G Penny, Hélène Bouchet, Suchinda Malaivijitnond, Ulrich H. Reichard, Klaus Zuberbühler

Publications

White-handed gibbons produce loud and acoustically complex songs when interacting with their neighbours or when encountering predators. In both contexts, songs are assembled from a small number of units although their composition differs in context-specific ways. Here, we investigated whether wild gibbons could infer the 'meaning' when hearing exemplars recorded in both contexts (i.e. 'duet songs' vs. 'predator songs'). We carried out a playback experiment by which we simulated the presence of a neighbouring group producing either its duet or a predator song in order to compare subjects' vocal and locomotor responses. When hearing a recording of a duet song, …

Supporting Safety Culture In Academia: Safety Communication Barriers, Emily Faulconer, Chelsea Lenoble

Publications

In the last decade, we have heard of multiple disturbing academic laboratory accidents resulting in significant injury and property damage. When these hit headlines, it can spur self-reflection across academic institutions. The unfortunate truth is that safety in academia tends to be problematic. Accidents happen regularly even if they do not make headlines, with post-accident analyses typically revealing systematic safety failures. As a result, the concept of safety culture has come into the spotlight.

Penn State’S School Of Public Affairs Security-Related Academic Programs Amid The Novel Coronavirus Catastrophe, Alexander Siedschlag

Publications

Due to its large OL student population, Penn State’s School of Public Affairs had (unintended) applicable crisis contingency protocols in place prior to the COVID-19 outbreak. With the support of our college’s Center for Teaching Excellence, many traditional F2F residential courses had already been set up on our learning management system (LMS), Canvas. As a result, many of our school’s traditional students and faculty had a handle on using Canvas and remote learning technology. The center enhanced and focused its services to faculty as COVID-19 evolved (Center for Teaching Excellence, 2020). As the COVID-19 crisis hit Penn State during the …

(Indigenous) Language As A Human Right, Kristen Carpenter, Alexey Tsykarev

Publications

The United Nations General Assembly has proclaimed 2022-2032 as the International Decade of Indigenous Languages. Building on lessons of the International Year of Indigenous Languages of 2019, the Decade will "draw attention to the critical loss of indigenous languages and the urgent need to preserve, revitalize and promote indigenous languages." These actions are necessary, in part, because existing laws and policies have proven inadequate to redress the legacy of state suppression of indigenous languages or ensure nondiscrimination in contemporary usage. In light of the International Year and Decade, this Article explores the rights of indigenous peoples to "use, revitalize, and …

Pushing The Envelope: Salzberg V. Sciabacucchi And Delaware's Evolving View Of The Internal Affairs Doctrine, Mark J. Loewenstein

Publications

In January, 2020, the Delaware Supreme Court handed down its decision in Salzberg v. Sciabacucchi, upholding a provision in a certificate of incorporation that designated the federal courts as the exclusive jurisdiction for the litigation of claims under the federal Securities Act of 1933. The inclusion of these provisions in Delaware charters and bylaws – often referred to as “Federal Forum Provisions” or FFPs – raised important questions as to the reach of the internal affairs doctrine. This doctrine provides that the jurisdiction of incorporation regulates the internal affairs of its corporations: the relationship among and between the corporate …

Facilitating Collaborative Metadata Creation For Faculty-Initiated Digital Projects, R. Cecilia Knight, Elizabeth Rodrigues, Rebecca Ciota

Publications

The usability and long-term preservation of digital humanities projects, such as a digital archive or other project built around digitized materials, depend on thoughtful and thorough metadata creation. The variety of expertise required to create high-quality metadata for digital humanities projects practically requires a collaborative approach. Putting the call for collaboration into practice requires tools that are accessible and functional for all collaborators. Research on tools for metadata creation has tended to focus either on tools for librarians to manage digital project metadata or on tools for independent author metadata creation (Greenberg, 2003; Crystal & Greenberg, 2005). The …
