Exercise Breaks, Unm Prevention Research Center

Exercise Breaks

Exercise Breaks are designed to be short in duration, and require a small space and little-to-no equipment. Exercise Breaks are a great way to transition children from one activity to the next and help them to be more focused throughout the day. Exercise Breaks can be performed in the classroom, outside, or in a large room such as a gymnasium or meeting room. Exercise Breaks can be conducted with center staff and parents during meetings.

Fearful Asymmetry: How The Absence Of Public Participation In Section 7 Of The Esa Can Make The 'Best Available Science' Unavailable For Judicial Review, Travis O. Brandon

Law Faculty Scholarship

Recent empirical studies have shown that public participation is an essential part of the listing process of the Endangered Species Act (“ESA”) because it provides the wildlife agencies with valuable scientific information regarding candidate species and forces agencies to make politically unpopular decisions to protect species standing in the way of development interests. However, the crucial agency-forcing mechanism of public participation is lacking in the interagency consultation process in section 7 of the ESA, one of the most important provisions by which the ESA’s protections for listed species are enforced. This Article explains how the absence of public input through …

From Youth Sports To Collegiate Athletics To Professional Leagues: Is There Really 'Informed Consent' By Athletes Regarding Sports-Related Concussions?, Tracey Carter

Law Faculty Scholarship

Traumatic brain injury (TBI) is a major public health issue in the United States. A sports-related concussion is a form of TBI that can occur from participation in both contact and non-contact sports and recreational activities. The Centers for Disease Control and Prevention estimates that 1.6 to 3.8 million sports- and recreation-related concussions occur in the United States every year. This article emphasizes the serious impact of TBI on youth, collegiate, and professional athletes, explores whether athletes are really “informed” regarding sports-related concussions, and provides recommendations to better protect athletes and to decrease the number of sports-related concussions.

Keep Out Fda: Food Manufacturers' Ability To Effectively Self-Regulate Front-Of-Package Food Labeling, Ellen A. Black

Law Faculty Scholarship

The headlines on any given day claim that the American "obesity epidemic" continues to worsen.' According to these headlines, Americans, both adults and children, are increasingly becoming more obese, are more likely to be diagnosed with diabetes, and will likely prematurely die due to this preventable disease. Numerous private industries, as well as the government, seek to rescue Americans from this crisis. As the obesity epidemic debate intensifies, the call for more government regulation correspondingly grows. There are critics, however, who question the legitimacy of this epidemic and the need for more regulation. For example, some well-known scholars opine that …

Comprehensive Self-Selected Reading And Student Engagement With The Novel: A Program Evaluation, Jennesis Kathleen Jensen

Doctoral Dissertations

Not reading (Krashen, 2009) is a phenomenon widely noted in students assigned to read as a part of school curriculum. A solution to the many criticisms and deficits cited in the literature surrounding the practice of not reading may lie in the CSSR (Comprehensive Self-Selected Reading) program chosen for focus in this study. In this high school student-reading program, incoming students are guided through a process of textual self-selection and evaluation in an enthusiastic, engaging, and motivating manner. During an eight-month study duration, thirty-two 10th grade students actively read a total of 24,419 pages collaboratively, and 763.09 pages on average. …

The Effect Of Simulation With Debriefing For Meaningful Learning In Courses Of Nursing Theory And Practicum On Student Knowledge And Perception Of Instruction, Kathleen L. Shea

Doctoral Dissertations

Nursing students are expected to apply knowledge from lectures and laboratories to the clinical setting. One major challenge of nursing educators is facilitating the transfer of knowledge to the clinical-practice setting. Simulation-based education provides students with an experiential-learning activity within the context of a simulated clinical environment. Following the simulation activity, the instructor facilitates a debriefing session and guides student discussion and reflection related to the experience. Debriefing promotes understanding of nursing concepts (Benner, Sutphen, Leonard, & Day, 2010).

The purpose of this research is to compare two debriefing methods: traditional method and Debriefing for Meaningful Learning DML (Dreifuerst, 2012). …

Identification And Comparative Analysis Of Subolesin/Akirin Ortholog From Ornithodoros Turicata Ticks, Hameeda Sultana, Unnati Patel, Daniel E. Sonenshine, Girish Neelakanta

Biological Sciences Faculty Publications

Background: Subolesin is an evolutionary conserved molecule in diverse arthropod species that play an important role in the regulation of genes involved in immune responses, blood digestion, reproduction and development. In this study, we have identified a subolesin ortholog from soft ticks Ornithodoros turicata, the vector of the relapsing fever spirochete in the United States.

Methods: Uninfected fed or unfed O. turicata ticks were used throughout this study. The subolesin mRNA was amplified by reverse transcription polymerase chain reaction (RT-PCR) and sequenced. Quantitative-real time PCR (QRT-PCR) was performed to evaluate subolesin mRNA levels at different O. turicata developmental stages …

Governments have committed to conserving greater than or equal to 17% of terrestrial and greater than or equal to 10% of marine environments globally, especially "areas of particular importance for biodiversity" through "ecologically representative" Protected Area (PA) systems or other "area-based conservation measures", while individual countries have committed to conserve 3-50% of their land area. We estimate that PAs currently cover 14.6% of terrestrial and 2.8% of marine extent, but 59-68% of ecoregions, 77-78% of important sites for biodiversity, and 57% of 25,380 species have inadequate coverage. The existing 19.7 million km super(2) terrestrial PA network needs only 3.3 million …

Quantifying Florida Bay Habitat Suitability For Fishes And Invertebrates Under Climate Change Scenarios, Kelly A. Kearney, Mark J. Butler Iv, Robert Glazer, Christopner R. Kelble, Joseph E. Serafy, Erik Stabenau

Biological Sciences Faculty Publications

The Florida Bay ecosystem supports a number of economically important ecosystem services, including several recreational fisheries, which may be affected by changing salinity and temperature due toclimate change. In this paper, we use a combination of physical models and habitat suitability index models to quantify the effects of potential climate change scenarios on a variety of juvenile fish and lobster species in Florida Bay. The climate scenarios include alterations in sea level, evaporation and precipitation rates, coastal runoff, and water temperature. We find that the changes in habitat suitability vary in both magnitude and direction across the scenarios and species, …

Mutations in the Plasmodium falciparum chloroquine resistance transporter, PfCRT, are the major determinant of chloroquine resistance in this lethal human malaria parasite. Here, we describe P. falciparum lines subjected to selection by amantadine or blasticidin that carry PfCRT mutations (C101F or L272F), causing the development of enlarged food vacuoles. These parasites also have increased sensitivity to chloroquine and some other quinoline antimalarials, but exhibit no or minimal change in sensitivity to artemisinins, when compared with parental strains. A transgenic parasite line expressing the L272F variant of PfCRT confirmed this increased chloroquine sensitivity and enlarged food vacuole phenotype. Furthermore, the introduction …

A Popular And Potentially Sustainable Fishery Resource Under Pressure-Extinction Risk And Conservation Of Brazilian Sciaenidae (Teleostei: Perciformes), Ning L. Chao, Flávia L. Frédou, Manuel Haimovici, Monica B. Peres, Beth Polidoro, Marcelo Raseira, Rosana Subira, Kent E. Carpenter

Biological Sciences Faculty Publications

Croakers (Sciaenidae) are major fishery resource in Brazil; constituting 22% of marine and 9% of freshwater fishery landings. Croakers are subject to heavy fishing pressure throughout Brazil, but habitat alteration is also an important threat to regional populations. In this regional Sciaenidae assessment, each species was analyzed for relative risk of extinction, including the identification and quantification of the impact of major threats and existing conservation measures, based on application of the Categories and Criteria of the IUCN Red List of Threatened Species. Of the 52 species of Sciaenid fishes (34 marine and 18 freshwater) present in Brazilian waters, the …

Dynamic Ocean Management: Defining And Conceptualizing Real-Time Management Of The Ocean, Sara M. Maxwell, Elliot L. Hazen, Rebecca L. Lewison, Danial C. Dunn, Helen Bailey, Steven J. Bograd, Dana K. Briscoe, Sabrina Fossette, Alistair J. Hobday, Meredith Bennett

Biological Sciences Faculty Publications

Most spatial marine management techniques (e.g., marine protected areas) draw stationary boundaries around often mobile marine features, animals, or resource users. While these approaches can work for relatively stationary marine resources, to be most effective marine management must be as fluid in space and time as the resources and users we aim to manage. Instead, a shift towards dynamic ocean management is suggested, defined as management that rapidly changes in space and time in response to changes in the ocean and its users through the integration of near real-time biological, oceanographic, social and/or economic data. Dynamic management can refine the …

Comparative Population Genetics Of Two Invading Ticks: Evidence Of The Ecological Mechanisms Underlying Tick Range Expansions, Robyn Nadolny, Holly Gaff, Jens Carlsson, David Gauthier

Biological Sciences Faculty Publications

Two species of ixodid tick, Ixodes affinis Neumann and Amblyomma maculatum Koch, are simultaneously expanding their ranges throughout the mid-Atlantic region of the US. Although we have some understanding of the ecology and life history of these species, the ecological mechanisms governing where and how new populations establish and persist are unclear. To assess population connectivity and ancestry, we sequenced a fragment of the 16S mitochondrial rRNA gene from a representative sample of individuals of both species from populations throughout the eastern US. We found that despite overlapping host preferences throughout ontogeny, each species exhibited very different genetic and geographic …

Predicting Social Networking Site (Sns) Use: Personality, Attitudes, Motivation And Internet Self-Efficacy, Jin-Liang Wang, Linda A. Jackson, Hai-Zhen Wang, James Gaskin

Faculty Publications

Few studies have considered the personal characteristics that may predict the use of Social Networking Sites (SNSs). We examined the prediction of SNS use from distinct personality traits (i.e., sociability and shyness), attitudes toward SNS use, motivations for SNS use and Internet self-efficacy. Participants were 352 Chinese college students who used the QQ zone. Results indicated that sociability, shyness, attitudes, motivations and self-efficacy predicted SNS use, prediction depending on the function of SNS use. Specifically, sociability, attitudes, social interaction motivation, entertainment motivation and self-efficacy were significant predictors of SNS’s social function. In contrast, shyness, attitudes, relaxing entertainment motivation and self-efficacy …

Spectral Results For The Blue Plume Stars In Canis Major Overdensity, Mirza Sharoz Rafiul Islam

Theses and Dissertations--Physics and Astronomy

We present distances and kinematics and look at the possible populations for the blue plume (BP) stars in the Canis Major Overdensity (CMa). We conducted a medium resolution spectral survey on the BP stars (N=303) in CMa (centered at l = 238° ; b = -8°) using the data from AAOmega Spectrograph. We used a modified version of the Statistics-sensitive Non-linear Iterative Peak-clipping (SNIP) algorithm to normalize our fluxed absorption spectra. After determining the radial velocities from measurements of strong absorption features for the stars we use a Bayesian analysis of spectral feature strengths and photometric colors to determine Teff, …

A Study On Atomically Thin Ultra Short Conducting Channels, Breakdown, And Environmental Effects, Abhishek Sundararajan

Theses and Dissertations--Physics and Astronomy

We have developed a novel method of producing ultra-short channel graphene field effect devices on SiO₂ substrates and have studied their electrical transport properties. A nonlinear current behavior is observed coupled with a quasi-saturation effect. An analytical model is developed to explain this behavior using ballistic transport, where the charge carriers experience minimal scattering. We also observe multilevel resistive switching after the device is electrically stressed. In addition, we have studied the evolution of the electrical transport properties of few-layer graphene during electrical breakdown. We are able to significantly increase the time scale of break junction formation, and we …

Search For A Permanent Electric Dipole Moment Of 225Ra, Mukut R. Kalita

Theses and Dissertations--Physics and Astronomy

The observation of a permanent electric dipole moment (EDM) in a non-degenerate system would indicate the violation of discrete symmetries of Time reversal (T) or combined application of Charge (C) and Parity (P) symmetry violation through the CPT theorem. The diamagnetic ²²⁵Ra atom with nuclear spin I=1/2 is a favorable candidate for an EDM search. Experimental sensitivity to its EDM is enhanced due to its high atomic mass and the increased Schiff moment of its octupole deformed nucleus. An experimental setup is developed where laser cooled neutral radium atoms are collected in a …

Measurement Of The Dμd Quartet-To-Doublet Molecular Formation Rate Ratio (Λq : Λd) And The Μd Hyperfine Rate (Λqd) Using The Fusion Neutrons From Μ− Stops In D2 Gas, Nandita Raha

Theses and Dissertations--Physics and Astronomy

The MuSun experiment will determine the μd capture rate (μ−+d ->n+n+ν_e) from the doublet hyperfine state Λ_d, of the muonic deuterium atom in the 1S ground state to a precision of 1.5%. Modern effective field theories (EFT) predict that an accurate measurement of Λ_d would determine the two-nucleon weak axial current. This will help in understanding all weak nuclear interactions such as the stellar thermonuclear proton-proton fusion reactions, the neutrino reaction ν+d (which explores the solar neutrino oscillation problem). It will also help us understand weak …
