Brain-Based Learning: Implications For The Elementary Classroom, Brenda Van Roekel

Master of Education Program Theses

Recent developments in neuroscience have enabled scientists to understand and image brain activity. Brain researchers are now more able than ever before to understand how the brain works, what affects the brain, and what implications these discoveries have for education. Based upon these discoveries new methods of teaching have been devised using the term, brain-based strategies or brain-based learning. This thesis examines some of the brain-based strategies embraced by leaders in this field. It will pay particular attention to the enriched environment, the effect of emotion on learning, and the concept of sensitive or critical periods. It will examine research …

Creating A Strong Family: Strengthening Families And Communities In Times Of Crisis And Uncertainty, John Defrain

University of Nebraska-Lincoln Extension: Historical Materials

Strong families rise above crisis by working together toward a common goal. Perhaps we can all find a common vision in the world, one that recognizes the universal need for safety, security and positive human connection.

Nf526 Spring Millers, Ronald C. Seymour, Gary L. Hein

University of Nebraska-Lincoln Extension: Historical Materials

Biology, migration, and management of spring millers.

Millers can be abundant in and around homes each year, especially in May and early June. At this time of year, the moths are most likely the adult stage of the army cutworm, a common pest of wheat and alfalfa.

When millers emerge and begin to move westward in the spring, area residents have little recourse but to patiently await their departure. There are a few tactics, however, that can help lessen moth activity in and around homes:

Keep outside lighting to a minimum. These night-flying moths are attracted to lights. A porch …

G02-1444 Medical Sharps Disposal From Livestock Operations, Dicky D. Griffin, Marilyn Buhman

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to properly dispose of medical sharps (hypodermic needles and scalpel blades) for livestock operations. Understanding this is critical for employee safety and environmental stewardship.

Disposing livestock medical sharps presents two concerns. The first is human safety. Handling livestock medical sharps presents a potential employee safety concern and as such is addressed within the United States Occupational Safety and Health Administration (OSHA) regulations. Second, the disposal of livestock medical sharps presents an environmental hazard and as such is addressed within the United States Environmental Protection Agency (EPA) regulations.

G02-1443 Care Of Veterinary Vaccine Syringes, Dicky D. Griffin, Steve Ensley, David R. Smith, Grant Dewell, Marilyn Buhman

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains the basics of veterinary vaccine syringe cleaning and care.

Inadequately cleaned vaccine syringes are often responsible for localized infections associated with vaccination. Swellings around the injection site is common, especially when killed vaccines such as clostridial bacterins are given subcutaneously. Generally, these swellings can be considered good evidence that the animal is developing a proper immune response, but if the injection site swelling is greater than a small hen's egg, the swelling may be due to infection and should be examined.

Nf02-518 Management Of Phytophthora Diseases Of Soybeans, Loren J. Giesler, Jane A. Christensen, Christopher M. Zwiener

University of Nebraska-Lincoln Extension: Historical Materials

Phythophthora diseases of soybean, caused by Phytophthora sojae, are present wherever soybeans are grown in Nebraska. The pathogen survives primarily as "resting" spores in the soil or in association with infested crop debris. Symptoms associated with Phytophthora sojae, infections include seed rots, pre- and post-emergence dampin goff of seedlings and stem rot of plants at various growth stages.

Knowledge of the races present in the state and how varieties with different resistance genes have performed in a grower's field is critical to variety selection for maximum profitability.

Nf02-506 Plant Disease Central Web Site, Jim Stack

University of Nebraska-Lincoln Extension: Historical Materials

Disease is a natural part of every crop production system. This is true for all crop species and for each type of production system; irrigated or rain-fed, conventional or conservation tillage, and continuous or rotational cropping. In any given year, the question is which diseases will occur in Nebraska's field crops and at what incidence and severity.

To help producers, consultants, and other agricultural professionals diagnose and manage field crop diseases in Nebraska, the Plant Disease Central (PDC) web site was developed. The home page includes instructions on navigating the site under the "About This Site" link.

Ec02-177 Purple Loosestrife, Stevan Z. Knezevic

University of Nebraska-Lincoln Extension: Historical Materials

Purple loosestrife (Lythrum salicaria) is an introduced invasive weed that isover running thousands of acres of wetlands and waterways in the Midwest. Once purple loosestrife invades a wetland, natural habitat is lost and the productivity of native plant and animal communities is severely reduced. These losses in turn interfere with various levels of the ecosystem and area recreational activities such as fishing, boating and hunting, diminishing revenue from tourism and impairing the social and economic well being of local communities. A single control measure cannot provide long-term, sustainable control of this weed. An integrated approach, using a variety …

Ec02-174 Noxious Weeds Of Nebraska: Leafy Spurge, Robert A. Masters, Brady Kappler

University of Nebraska-Lincoln Extension: Historical Materials

Leafy spurge is an invasive weed that infests over three million acres in the northern Great Plains and the prairie provinces of Canada. It is commonly found in rangelands, pastures, roadsides, rights-of-way, and woodlands. Leafy spurge can reduce rangeland and pasture carrying capacity by as much as 75 percent because it competes with forages and cattle avoid grazing areas infested with this weed.

This Extension Circular discusses the biology, identification, distribution and control of leafy spurge.

Storm Deposition Of Pisoids In The Humboldt Oolite Member Of The Gilmore City Formation (Mississippian), North-Central Iowa, Shawn C. Thomas, John R. Groves

Journal of the Iowa Academy of Science: JIAS

Pisoids (concentrically laminated carbonate grains, > 2 mm in diameter) are abundant in the upper Humboldt Oolite Member of the Gilmore City Formation (Mississippian). Their cortices are isopachous and nuclei include both intraclasts and fragments of preexisting

pisoids. They occur both as floating grams m a fine grainstone matrix and concentrated at the bases of distinct layers that may be crudely graded beds. Sorting characteristics and the presence of broken and abraded pisoids suggest not only their origin as primary free grams, but also storm influence in the deposition of local pisolite layers. Regionally, the upper Humboldt Oolite is characterized by …

Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland

Journal of the Iowa Academy of Science: JIAS

Many species of grassland birds have been shown to avoid smaller fields. The avoidance of smaller fields, however, has not been consistently reported; avoidance may occur in one study, but not in another. To examine one possible reason for these inconsistencies, we examined how landscape composition influenced the relations between occurrence or abundance and field size. The study took place during the 1998 breeding season on 44 Conservation Reserve Program (CRP) fields located in Adair, Ringgold, and Union counties. The relations between occurrence, abundance, and field size were not influenced by landscape composition for any species.

Factors Influencing The Occurrence Of Birds That Use Feeders In Iowa, David Joseph Horn, Steve E. Fairbairn, Richard J. Hollis

Journal of the Iowa Academy of Science: JIAS

Since its inception in 1984, data from the annual Iowa "Winter Bird Feeder Survey" have provided valuable information about birds that use feeders in Iowa such as spatial and temporal population trends. Using data from the 1988 and 1994 Surveys, we examined how the occurrence of bird species that use feeders was influenced by geographic location, the habitat surrounding a house, and the types of seeds offered at a house. Of the 23 species examined, the occurrence of 8 species was influenced by latitude, 22 species were influenced by the habitat surrounding the house, and 22 species were influenced by …
