The Impact Of Guided Vs. Self-Directed Instruction On Student's Information Literacy Skills, Christiane Schroeter, Lindsey Higgins

Agribusiness

Purpose of the Study. Given the shift toward an increasingly knowledge-based economy, educators and employers have expressed the desire to emphasize students’ information literacy. Being information literate extends beyond the classroom setting and provides skills for independent investigations needed in internships and professional positions in marketing. However, in order to most effectively teach information literacy, what teaching styles are most appropriate? Should students be guided by the instructor or develop skills as independent learners? Our study determines the impact of a guided versus self-directed instruction method on students’ information literacy skills.

Method/Design and Sample. Using a survey with objective and …

A Website Of Agriculturally Related Activities For Elementary Grade Levels, Bailey M. Kirby

Agricultural Education and Communication

The purpose of this project is to develop a website containing agriculturally-related activities designed for the elementary classroom, including kindergarten to fifth grade. This website was created in order to bring agriculture into the elementary classroom and introduce the topic to students at an earlier age because the subject is currently only taught at the high school level. Two activities were created for each grade level and fit into the current curriculums for those grade levels. The website was designed in a way that teachers will be able to continually submit activities to be added to the website at any …

Building Conflict-Free Fft Schedules, Stephen Richardson, Dejan Markovic, Andrew Danowitz, John Brunhaver, Mark Horowitz

Computer Science and Software Engineering

A conflict-free schedule lets an FFT run to completion without ever having to pause for memory-conflict resolution. We show how to build such schedules for FFTs having any number of butterfly units B operating at any radix R, transforming any number of datapoints D. Our algorithm works for FFT datapaths with or without pipeline overlap, and for memory banks having any number of access ports. Specifically, it enables construction of conflict-free schedules using single-ported memory banks, which require less area than more traditional multi-ported designs.

Measuring The Strength Of The Semantic Relationship Between Words, Lubomir Stanchev

Computer Science and Software Engineering

We propose a novel way for extracting the strength of the semantic relationship between words from semi-structured sources, such as WordNet. Unlike existing approaches that only explore the structured information (e.g., the hypernym relationship in WordNet), we present a framework that allows us to utilize all available information, including natural text descriptions. Our approach constructs a similarity graph that stores the strength of the semantic relationship between words. Specifically, an edge between two words describes the probability that someone who is interested in resources about the first word will be also interested in resources about the second word. Note that …

Role Of Bacterial-Fungal Interactions On Heavy Metal Phytotoxicity In Serpentine Soil, Mihiri Seneviratne, Gamini Seneviratne, H. M. S. P. Madawala, M.C.M. Iqbal, Nishanta Rajakaruna, Tharanga Bandara, Meththika Vithanage

Biological Sciences

This study was conducted to understand the role of bacterial–fungal interactions on heavy metal uptake by Zea mays plants. A pot experiment was conducted for 90 days with Z. mays in serpentine soil inoculated with a Gram-negative bacterium, fungus (Aspergilllus sp.) and both microbes to determine the effects of inoculation on nickel, manganese, chromium and cobalt concentrations in plant tissue and soil. Soil nutrients and soil enzyme activities were measured to determine the effect of inoculations on soil quality. Inoculation of microorganisms increased shoot and root biomass, and the maximum biomass was in the bacterial–fungal inoculation. This could be …

Calcium : Magnesium Ratio Affects Environmental Stress Sensitivity In The Serpentine-Endemic Alyssum Inflatum (Brassicaceae), Rasoul Ghasemi, Zohreh Zare Chavoshi, Robert S. Boyd, Nishanta Rajakaruna

Biological Sciences

Plants endemic to serpentine soils are adapted to harsh environmental conditions typical of those soils, particularly, low (<1) calcium (Ca) : magnesium (Mg) ratios. We compared survival of two perennial Alyssum species native to Iran under experimental manipulations of Ca : Mg ratio, including when Ca : Mg ratio was varied under conditions of high ammonium concentration and heat stress. Alyssum inflatum is a serpentine endemic capable of nickel (Ni) hyperaccumulation, whereas A. lanceolatum is found on non-serpentine soils and is not known to hyperaccumulate Ni. We grew plants of both species under four Ca : Mg ratios (0.4, 2, 20, 40) and tested survival when plants were exposed to elevated ammonium …

An Analysis Of Strategic Treatment Interruptions During Imatinib Treatment Of Chronic Myelogenous Leukemia With Imatinib-Resistant Mutations, Dana Paquin, David Sacco, John Shamshoian

Mathematics

Chronic myelogenous leukemia (CML) is a cancer of the white blood cells that results from increased and uncontrolled growth of myeloid cells in the bone marrow and the accumulation of these cells in the blood. The most common form of treatment for CML is imatinib, a tyrosine kinase inhibitor. Although imatinib is an effective treatment for CML and most patients treated with imatinib do attain some form of remission, imatinib does not completely eradicate all leukemia cells, and if treatment is stopped, all patients eventually relapse (Cortes, 2005). In Kim (2008), the authors developed a mathematical model for the dynamics …

Transfer Of Heavy Metals Through Terrestrial Food Webs: A Review, Jillian E. Gall, Robert Boyd, Nishanta Rajakaruna

Biological Sciences

Heavy metals are released into the environment by both anthropogenic and natural sources. Highly reactive and often toxic at low concentrations, they may enter soils and groundwater, bioaccumulate in food webs, and adversely affect biota. Heavy metals also may remain in the environment for years, posing long-term risks to life well after point sources of heavy metal pollution have been removed. In this review, we compile studies of the community-level effects of heavy metal pollution, including heavy metal transfer from soils to plants, microbes, invertebrates, and to both small and large mammals (including humans). Many factors contribute to heavy metal …

A Preliminary Survey Of The Diversity Of Soil Algae And Cyanoprokaryotes On Mafic And Ultramafic Substrates In South Africa, Arthurita Venter, Anatoliy Levanets, Stefan Siebert, Nishanta Rajakaruna

Biological Sciences

Despite a large body of work on the serpentine-substrate effect on vascular plants, little work has been undertaken to describe algal communities found on serpentine soils derived from peridotite and other ultramafic rocks. We report a preliminary study describing the occurrence of algae and cyanoprokaryotes on mafic and ultramafic substrates from South Africa. Results suggest that slope and aspect play a key role in species diversity and community composition and, although low pH, nutrients and metal content do not reduce species richness, these edaphic features also influence species composition. Further, typical soil genera such as Leptolyngbya, Microcoleus, Phormidium …

Growth And Nickel Uptake By Serpentine And Non-Serpentine Populations Of Fimbristylis Ovata (Cyperaceae) From Sri Lanka, P. K. D. Chathuranga, S. K. A. T. Dharmasena, Nishanta Rajakaruna, M.C.M. Iqbal

Biological Sciences

Compared with serpentine floras of Southeast Asia, the serpentine vegetation of Sri Lanka is impoverished in regard to serpentine endemics and nickel hyperaccumulators. All species so far documented from the serpentine outcrops of Sri Lanka also have non-serpentine populations; it is unclear whether the serpentine populations are physiologically distinct and deserve ecotypic recognition. We conducted a preliminary study to examine whether serpentine and non-serpentine populations of Fimbristylis ovata represent locally adapted ecotypes by investigating their growth and potential for nickel uptake and tolerance under greenhouse conditions. Although both populations of F. ovata showed a similar growth pattern in serpentine soil …

Vegetation Dynamics And Mesophication In Response To Conifer Encroachment Within An Ultramafic System, J. Burgess, K. Szlavecz, N. Rajakaruna, S. Lev, C. Swan

Biological Sciences

The biological, ecological, and evolutionary significance of serpentine habitats has long been recognised. We used an integrated physiochemical dataset combining plot spatial data with temporal data from tree cores to evaluate changes in soils and vegetation. Data suggest that this unique habitat is undergoing a transition, endangering local biodiversity and endemic plant species. The objective of this work was to analyse the vegetation dynamics of a xeric serpentine savanna located in the Mid-Atlantic, USA. We employed vegetation surveys of 32 10 × 15 m quadrats to obtain woody species composition, density, basal area, and developed a spatial physiochemical dataset of …

Physics

In the Spring of 2011 we carried out a 2.5 month reverberation mapping campaign using the 3 m Shane telescope at Lick Observatory, monitoring 15 low-redshift Seyfert 1 galaxies. This paper describes the observations, reductions and measurements, and data products from the spectroscopic campaign. The reduced spectra were fitted with a multicomponent model in order to isolate the contributions of various continuum and emission-line components. We present light curves of broad emission lines and the active galactic nucleus (AGN) continuum, and measurements of the broad Hβ line widths in mean and rms spectra. For the most highly variable AGNs we …
