An In-Service Educational Program for Beginning Teachers of Spanish in the Elementary Grades

An In-Service Educational Program for Beginning Teachers of Spanish in the Elementary Grades

Date: June 1960
Creator: Robertson, John Clifford
Description: The problem of the study was to determine the effectiveness of an in-service education program as a means of providing qualified foreign language teachers for elementary schools. Specifically, the problem was concerned with a statistical comparison of the achievement of two groups of pupils. One group was composed of fourth-grade pupils who were taught Spanish by teachers who had had a maximum of three college hours in Spanish and who had participated in an in-service education program. The other group was composed of fourth-grade pupils whose teachers had had a minimum of twelve college hours in Spanish but had not participated in an in-service education program.

In-store Event Needs and Technology Use Among Half Price Books Customers

In-store Event Needs and Technology Use Among Half Price Books Customers

Date: December 2013
Creator: Wilson, Steven K.
Description: Half Price Books, Records, Magazines, Inc. (HPB), fills a unique niche by selling a variety of new, used and rare merchandise primarily in their chain of 116 stores in sixteen states and online. The company has noticed increased mobile device use among customers in their stores while sales have declined in recent years. To remain viable HPB is attempting to adapt to market forces in a timely manner while remaining continually interested in growth and innovation. A major part of adapting, growing, and innovating is the adoption and astute utilization of technology in-store and a more complete understanding of their customers’ activities and preferences. The goal is to make Half Price Books a more technologically savvy destination for shopping, community events, and entertainment. One purpose of this study is to give the company a better idea of how customers use technology in searching for merchandise including information searches generated in-store from mobile devices and how customers use the internet to find merchandise prior to and following their experiences in HPB’s stores. Another important purpose is to also determine what kinds of events such as book signings, poetry readings and other special events customers would like to see at Half Price ...

In Vitro Cortical Networks for Disease Modeling and Drug Evaluation

In Vitro Cortical Networks for Disease Modeling and Drug Evaluation

Date: December 2013
Creator: Wu, Calvin
Description: In translational research, disease models in preclinical studies are used as media for discovery of drugs or novel therapeutics. Development of in vitro models for various neurological diseases that enable efficient pharmacological or toxicological screening has been ongoing but challenging. Recognizing the potential benefit of in vitro disease models, dysfunctions in the cortical neuronal networks were induced to mimic the functional pathology of neurological symptoms using microelectrode arrays. Two different disease states – tinnitusand excitotoxicity – were investigated and discussed. In this model, pentylenetetrazol-induced increase in spontaneous firing rate and synchrony in the auditory cortical networks was used as correlate of tinnitus. Potential tinnitus treatment drugs from several different classes – including the novel class of potassium channel openers – were screened and quantified. The potentialtherapeutic values of these drugs were also discussed as the basis for drug repurposing. Functional excitotoxicity was induced by cisplatin (a cancer drug that causes neurological sideeffects) and glutamate (the major excitatory neurotransmitter). As proof-of-principle that the model may contribute to expediting the development of therapeutics, cisplatin excitotoxicity wasprevented by the antioxidant D-methionine, while glutamate excitotoxicity was prevented by ceftriaxone (a modulator of a glutamate reuptake transporter). In the latter part of the study, with ...

In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens

In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens

Date: December 2009
Creator: Bakshi, Vibhu
Description: Plant estrogens have long been associated with health benefits. The potential of tissue culture techniques for the production of several secondary metabolites has been known for many years. Tissue cultures stimulate the production or induce the biosynthesis of novel compounds not found in the mature plant. Tissue culture of Morus alba, family Moraceae, is known to contain phytoestrogens, was established on plant-hormone supplemented Murashige and Skoog (MS) medium. Petiole and the stem tissue from mature trees were the best explants for initiation and proliferation of calli. The best callus proliferation was obtained on MS medium containing 1-napthalene acetic acid (1mg/ml) and benzylaminopurine (0.5mg/ml) for M. alba. Comparison of phytoestrogens of Moraceae species from in vivo and in vitro tissue isolation were carried out. The estrogenic activities of callus extracts were assayed in an estrogen-responsive yeast system expressing the human estrogen receptor alpha. Male callus extracts had higher estrogenic activity than male and female extracts from in vivo and in vitro tissues. Isolation and characterization of phytoestrogens from above tissues were carried out using solid phase extraction, high perfomance liquid chromatography and mass spectrometry techniques. Biochanin A, an isoflavonoid, was isolated as one of the compounds in male callus extracts. Biochanin ...

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

Date: 1950
Creator: Heather, Carl D.
Description: In this study twelve types of top soil were collected under aseptic conditions. The cellulose-decomposing rates of these were compared in order to determine the relative rates in the cellulose-decomposing potential of the microorganisms involved. Furthermore, this investigation is designed to acquire pertinent information on the rate at which natural cellulose materials are returned to available plant food.

In Vitro Studies of Nuclear Changes in Mammalian CNS Neurons Subjected to Rapid Acceleration Impact Injury

In Vitro Studies of Nuclear Changes in Mammalian CNS Neurons Subjected to Rapid Acceleration Impact Injury

Date: May 1995
Creator: Wolf, Amy
Description: An in vitro model of Rapid Acceleration Impact (RAI) Injury was used to study the effects of multiple impact (220 g/impact, 3-5 sec intervals) trauma on cultures of murine CNS cells. Investigations with spinal cord cultures showed that 1) multiple impacts delivered tangential to the plane of cell growth caused neuronal death (12% after 3 impacts to 46% after 10 impacts); 2) multiple impacts delivered normal to the plane of cell growth were much less effective (8% dead after 10 impacts); 3) most neuronal death occurred within 15 minutes after injury 4) morphological changes observed included increased nuclear prominence and somal swelling; and 5) pretreatment with ketamine (0.1mM) reduced cell death from 51 to 14% and reduced somal swelling. Identical studies performed on cortical cultures revealed minimal differences between the two tissues in their response to multiple tangential impacts.
