This article summarizes the findings of the environmental scan, including number of contact hours, …

Materials And Environments That Promote Learning In The Primary Years .G2199, Jennifer Gerdes, Tonia Renee Durden, Leanne Manning

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

Teachers can use multiple strategies to create a stimulating and responsive environment for children in the primary years. These strategies can lead to children’s overall social, emotional, physical, and cognitive development.

To promote optimal development of the whole child, children need a variety of materials available to them daily that provide both challenge and success. They also need daily exposure to music, art, and movement activities.

Elevational Distribution And Conservation Biogeography Of Phanaeine Dung Beetles (Coleoptera: Scarabaeinae) In Bolivia, Sebastian K. Herzog, A. Caroli Hamel-Leigue, Trond H. Larsen, Darren J. Mann, Rodrigo W. Soria- Auza, Bruce D. Gill, William D. Edmonds, Sacha Spector

Entomology Papers from Other Sources

Insect macroecology and conservation biogeography studies are disproportionately scarce, especially in the Neotropics. Dung beetles are an ideal focal taxon for biodiversity research and conservation. Using distribution and body size data on the ecologically important Phanaeini, the best-known Neotropical dung beetle tribe, we determined elevational patterns of species richness, endemism, body size, and elevational range in Bolivia, specifically testing Bergmann’s and Rapoport’s rule. Richness of all 39 species and of 15 ecoregional endemics showed a hump-shaped pattern peaking at 400 m, but overall declined strongly with elevation up to 4000 m. The relationship between endemic and total species richness appeared …

Law Clinics And Lobbying Restrictions, Marcy L. Karin, Kevin Barry

Journal Articles

“Can law school clinics lobby?” This question has plagued professors for decades but has gone unanswered, until now. This Article situates law school clinics within the labyrinthine law of lobbying restrictions and concludes that clinics may indeed lobby. For ethical, pedagogical, and, ultimately, practical reasons, it is critical that professors who teach in clinics understand these restrictions. This Article offers advice to professors and students on safely navigating this complicated terrain.

Investigating Therapeutic Options For Lafora Disease Using Structural Biology And Translational Methods, Amanda R. Sherwood

Theses and Dissertations--Molecular and Cellular Biochemistry

Lafora disease (LD) is a rare yet invariably fatal form of epilepsy characterized by progressive degeneration of the central nervous and motor systems and accumulation of insoluble glucans within cells. LD results from mutation of either the phosphatase laforin, an enzyme that dephosphorylates cellular glycogen, or the E3 ubiquitin ligase malin, the binding partner of laforin. Currently, there are no therapeutic options for LD, or reported methods by which the specific activity of glucan phosphatases such as laforin can be easily measured. To facilitate our translational studies, we developed an assay with which the glucan phosphatase activity of laforin as …

Effects Of Antimicrobial Peptide Revealed By Simulations: Translocation, Pore Formation, Membrane Corrugation And Euler Buckling, Licui Chen, Nana Jia, Lianghui Gao, Weihai Fang, Leonardo Golubovic

Faculty & Staff Scholarship

We explore the effects of the peripheral and transmembrane antimicrobial peptides on the lipid bilayer membrane by using the coarse grained Dissipative Particle Dynamics simulations. We study peptide/lipid membrane complexes by considering peptides with various structure, hydrophobicity and peptide/lipid interaction strength. The role of lipid/water interaction is also discussed. We discuss a rich variety of membrane morphological changes induced by peptides, such as pore formation, membrane corrugation and Euler buckling.

Can Spatial Dependence Enhance Industry Sustainability? The Case Of Pasture-Based Beef, Inocencio Rodriguez, Gerard D'Souza, Thomas Griggs

Regional Research Institute Working Papers

Can sustainability be enhanced by maximizing the sum of private and social benefits from an industry? This might take place, for example, by identifying production options that increase profitability side-by-side with societal goals such as renewable energy production and carbon sequestration, healthier communities, environmental quality, and economic development. We explore this issue for pasture based beef (PBB), a nascent industry where industry profitability, community development, and quality of life can be enhanced by explicitly linking the PBB supply chain spatially and intertemporally, thereby increasing the sum of private and social benefits. We develop a framework based on optimal control theory …

The Rise Of Carrots And The Decline Of Sticks, Gerrit De Geest, Giuseppe Dari-Mattiacci

University of Chicago Law Review

There is a remarkable tendency in modern legal systems to increasingly use carrots. This trend is not limited to legal systems but can also be observed in, for instance, parenting styles, social control mechanisms, and even law schools' teaching methods. Yet, at first glance, sticks appear to be a more efficient means of inducing people to comply with legal rules or social norms because they are not meant to be applied (thus minimizing transaction costs and risks) and may cause fewer unintended distributional distortions. So how can we justify the widespread use of carrots? This Article shows that carrots can …

The Connected Lawyer: The Evolving 'Operating System' Of The Networked Professional, Patrick C. Brayer

Faculty Works

The legal profession must prepare for generations of networked law students and attorneys who demand interaction with a professional system in the same way they experience connection in their social system. As technology evolves, new professionals will expect more autonomy and control over their interactions. The central thesis of this Essay is that technology allows greater control of an individual’s professional interactions, and this control can provide a benefit, but devices of connection can also serve as a barrier to the authentic experiences that provide professional learning and innovation.

Human Rights Obligations To The Poor, Monica Hakimi

Book Chapters

Poverty unquestionably detracts from the human rights mission. Modern human rights law recognizes a broad range of rights - for example, "to life, liberty, and security of person" and to adequate "food, clothing, and medical care."1 Any number of those rights might go unrealized in conditions of extreme poverty. However, human rights law has always been partly aspirational. For those seeking to improve the lives of the poor, the key question is not what rights exist but how to make those rights operational. What does human rights law actually require of states? And how might its obligations benefit the poor?

Becoming-Belieber: Girls' Passionate Encounters With Bieber Culture, Kortney Sherbine

Teacher Education and Leadership Faculty Publications

In this article, I draw on French philosophers Gilles Deleuze and Félix Guattari’s (1987) notion of becoming to consider the ways in which these encounters with people, materials, and technologies are productive, creating space for Beliebers to come into relationship with one another and with popular culture in ways that are new and that I never could have anticipated during my more carefully organized and school-curriculum-driven interactions with girls during my six years as an elementary school teacher. Through my current research into young girls’ after-school fanaticism, I have been able to come to know girls differently than I knew …

The Effects Of Acute Nicotine Administration On Memory Formation And Neural Activity In The Hippocampus, Perirhinal Cortex, And Medial Septum: Implications For Neurodegenerative Disorders, Matthew Wishnoff

Behavioral Neuroscience Honors Papers

Within the general public, nicotine is commonly thought of as a harmful molecule due to its role in tobacco addiction. However, nicotinic stimulation of the cholinergic system has also been shown to enhance cognitive functioning. This enhancement is thought to be caused by an increase in the release of the neurotransmitter, acetylcholine (ACh), which is responsible for mediating a variety of cognitive processes, such as REM sleep and memory formation. Recent research by Melichercik and colleagues shows that systemic nicotine administration enhances memory acquisition for both object location and object recognition memory in rats, as assessed by a modified version …

Designing Contour Weep Berms To Reduce Agricultural Nonpoint Source Pollution, Richard C. Warner, Carmen T. Agouridis, Ross L. Guffey

Biosystems and Agricultural Engineering Faculty Publications

Nonpoint source pollution (NPS) of surface waters is a significant issue in agricultural lands, and best management practices (BMPs) are often used to reduce these impacts. Since the effectiveness of a BMP depends on a large number of widely varying factors, it is important to continue to develop BMPs in order to provide designers with more tools to use to maximize NPS removal. The contour weep berm is a new structural BMP constructed out of earth and subsequently vegetated. It is a linear BMP that is used in combination with a down-gradient vegetated filter strip or forested riparian buffer. Preliminary …

Lindsay’S Legacy: The Tragedy That Triggered Law Reform To Prevent Teen Dating Violence, D. Kelly Weisberg

UC Law SF Journal on Gender and Justice

Intimate partner violence is common not only among adults but among teenagers as well. A recent large-scale study reveals the startling fact that dating violence begins as early as age eleven. In 2005, an innovative state law reform movement was launched that confers a proactive role on the schools to prevent teen dating violence (TDV). Currently, twenty states have laws that address TDV in the schools, and additional states have pending legislation. This article explores the impetus for this law reform movement, provides an analysis of state laws on TDV prevention, and examines pending federal legislation that overcomes a fundamental …

Using Text Structures Of Information Books To Teach Writing In The Primary Grades, Sarah K. Clark, Cindy D'On Jones, D. Ray Reutzel

Teacher Education and Leadership Faculty Publications

Teaching children in the primary grades the text structures and features used by authors of information text has been shown to improve comprehension of information texts and provide the scaffolding and support these children need in order to write their own information texts. As teachers implement the English Language Arts Common Core State Standards (CCSS), they will need support and training on how to meet these increased curricular demands. In this article, we describe how children’s information books can be used as exemplars of well-structured text models to teach young students how to write selected discourse patterns required in the …

Combined Effects Of Rearing Environment And Lead (Pb2+) Exposure On Visuospatial Learning And Memory In Rats, Nicholas Tolman

Behavioral Neuroscience Honors Papers

Critical periods of neural development occur during early postnatal life that correspond with increases in synaptic plasticity and the formation of neural circuits needed for learning and memory. This development can be profoundly influenced by experience and negatively affected by environmental toxins. Environmental enrichment and lead exposure inversely affect mediators of synaptic plasticity, which suggests that enrichment may have an attenuating effect on lead induced cognitive deficits. A wealth of evidence has indicated that exposure to excessive amounts of inorganic Pb2+ during early development can produce long lasting cognitive deficits in humans. Evidence also suggests that children raised in an …

Smaf: A Soil Health Assessment Tool, D. L. Karlen, C. D. Nance, D. L. Dinnes, D. W. Meek

Journal of the Iowa Academy of Science: JIAS

The Soil Management Assessment Framework (SMAF) was developed to help quantify soil quality/health effects of tillage, crop rotation, and other soil management practices. Our objective was to determine if the SMAF could detect soil health differences after growing a single winter triticale (X Triticosecale Wittmack) crop. Soil samples were collected from 0 to 7.5- and 7.5 to 15- cm depth increments during the 2003 – 2004 and 2004 – 2005 growing seasons near Ames and Lewis, IA, and analyzed for several potential soil quality indicators. The SMAF analysis showed higher soil quality ratings for surface than subsurface samples. It also …

Using Power-Law Properties Of Social Groups For Cloud Defense And Community Detection, Justin L. Rice

Doctoral Dissertations

The power-law distribution can be used to describe various aspects of social group behavior. For mussels, sociobiological research has shown that the Lévy walk best describes their self-organizing movement strategy. A mussel's step length is drawn from a power-law distribution, and its direction is drawn from a uniform distribution. In the area of social networks, theories such as preferential attachment seek to explain why the degree distribution tends to be scale-free. The aim of this dissertation is to glean insight from these works to help solve problems in two domains: cloud computing systems and community detection.

Privacy and security are …

Engineering Microenvironments To Modulate Calcium Information Processing In Neuronal Cells, Kinsey Cotton Kelly

Doctoral Dissertations

Tissue engineered microenvironments were constructed to test the effects glial cells have on calcium information processing, and to mimic conditions in vivo for tumor invasion and residual cancer after resection of tumor. Submaximal, nM, glutamate (GLU) stimuli were applied to the engineered environments, and the resulting calcium dynamic behavior of neuronal cells was measured to help predict and interpret chaotic systems in the experimental realm. Calcium is a key signaling ion which signals through the N-methyl-D-aspartate (NMDA) glutamate receptor on the neuronal membrane. GLU binding to the NMDA receptor (NMDAR) causes a large and dynamic increase in neuronal intracellular calcium. …

How The Axe Falls: A Retrospective On Thirty-Five Years Of Sir Gawain And The Green Knight Performance, Linda Marie Zaerr

English Literature Faculty Publications and Presentations

This retrospective represents a new approach to using historical performance as a tool for understanding medieval narrative performance. The core of the article traces how an individual performer’s interaction with a stable medieval text both indicates directions medieval performers may have taken and suggests the limitations imposed by modern performance conventions. The discussion touches on issues of adaptation and translation, variation in troupe composition and audience, expectations of modern audiences, impact of costume choices, and limitations of audio and video recordings as documentation of live performance. Juxtaposing eight performances of a single passage clarifies how performance can transform a text, …

Affective Forecasting And Well Being, Barry Schwartz, R. Sommers

Psychology Faculty Works

Every decision requires a prediction, both about what will happen and about how the decider will feel about what happens. Thus, decisions require what is known as affective forecasting. This chapter reviews evidence that people systematically mispredict the way experiences will feel. First, predictions about the future are often based on memories of the past, but memories of the past are often inaccurate. Second, people predict that the affective quality of experiences will last, thereby neglecting the widespread phenomenon of adaptation. Third, in anticipating an experience, people focus on aspects of their lives that will be changed by the experience …

A Familial Privacy Right Over Death Images: Critiquing The Internet-Propelled Emergence Of A Nascent Constitutional Right That Preserves Happy Memories And Emotions, Clay Calvert

UC Law Constitutional Quarterly

In May 2012, the United States Court of Appeals for the Ninth Circuit broke new constitutional ground in Marsh v. County of San Diego when it held that the constitutional right to privacy encompasses "the power to control images of a dead family member." This article provides an overview of Marsh. It then discusses the historical common law right to familial privacy over death images. In addition, it explores both judicial and legislative recognition of the Internet's power as a force in the battle to preserve privacy. Next, it illustrates how these twin forces-the preexisting common law right to familial …

Tattoos & Ip Norms, Aaron K. Perzanowski

Faculty Publications

The U.S. tattoo industry generates billions of dollars in annual revenue. Like the music, film, and publishing industries, it derives value from the creation of new, original works of authorship. But unlike rights holders in those more traditional creative industries, tattoo artists rarely assert formal legal rights in disputes over copying or ownership of the works they create. Instead, tattooing is governed by a set of nuanced, overlapping, and occasionally contradictory social norms enforced through informal sanctions. And in contrast to other creative communities that rely on social norms because of the unavailability of formal intellectual property protection, the tattoo …
