    The author of this practicum developed and implemented a program to introduce global perspectives focusing on Haitian culture in a sixth grade class for learning disabled students. The program\u27s aim was developed to get the students to develop an understanding of Haitian culture and a perspective of feeling and caring for others of a Haitian background. The program contained seven strategies: film watching, game playing, food sampling, class discussions, story reading, Gestalt strategies and societal media involvement. All strategies were fully implemented throughout the ten weeks. At the conclusion of the program, all of the students showed a significant gain in understanding Haitian culture and a sense of caring for students of a Haitian background. Pretesting, an attitudinal questionnaire, and a weekly questionnaire were used for the author\u27s purpose of monitoring each student\u27s progress. The author considered this practicum to be of value throughout the county because of its multi-cultural diversity

D.) University of Missouri-Columbia 2005.Dissertations, Academic -- University of Missouri--Columbia -- Mechanical and aerospace engineering.The in-situ response of WC-Ni and WC-Co composites under compressive loading was measured using neutron diffraction techniques. These measurements give a clear indication of the elastic strain behavior of both the carbide and metal binder phases in directions both axial and transverse to the applied load. Residual stress measurements were also made on as-produced samples and on those samples which had been mechanically loaded. These measurements show a substantial relaxation in the initial thermal residual stresses of the cemented carbides with high binder content, most of which occurs by the end of the first load-unload cycle. This relaxation in residual stress is also found to be anisotropic, relaxing more in the direction transverse to the loading axis than in the direction parallel to the loading axis. Strain distribution was considered by observing the change in peak widths in the diffraction data. Taken as a whole, the data suggests a profound role for thermal residual stress and the point-to-point variation of residual stress in the response of cemented carbides to applied load. Localized yielding on the scale of the microstructure which acts to absorb energy is proposed as a mechanism for the superior toughness of these materials

    Ignite: Not Just Surviving PBIS, But Succeeding: 1st Year Success Toolkit (Group 2)

    Get PDF
    This presentation will target schools that are in the installing phase or planning phase. However, the presentation could also benefit schools that may not have had a successful implementation year due to a variety of reasons. The presentation will focus on 7 critical components (tools) Stockbridge Elementary School utilized during Year 1 of implementing the PBIS framework. By using these tools SES reduced the number of office referrals by 33%. The 7 success tools are: Community Buy-In, Strategic Introduction to Student Body, Planned PBIS Leadership Meetings, PBIS Student Ambassadors, Constant Reflection of Practices / Procedures, Effective and Consistent Acknowledgement System, and Data-Driven Decision Making. During the session participants will be actively engaged in the practices that allowed SES to have a successful 1st year of implementation. Presenters will give examples of how each tool assisted with ensuring the PBIS framework was implemented with fidelity. The presentation will also allow participants to reflect on their practices and build a toolkit that will allow their school to successfully implement PBIS. In addition to hearing from teachers, the presentation will include feedback from the school’s principal. As we all know, PBIS is a very intricate framework that must be implemented with fidelity. The presentation will highlight the importance of using the TFI and how each success tool is linked to a particular item on the TFI. The presentation will focus on the 15 items in Tier I

    Serotoninergic modulation of sensory transmission to brainstem reticulospinal cells

    Sensory inputs are subjected to modulation by central neural networks involved in controlling movements. It has been shown that serotonin (5‐HT) modulates sensory transmission. This study examines in lampreys the effects of 5‐HT on sensory transmission to brainstem reticulospinal (RS) neurons and the distribution of 5‐HT cells that innervate RS cells. Cells were recorded intracellularly in the in vitro isolated brainstem of larval lampreys. Trigeminal nerve stimulation elicited disynaptic excitatory responses in RS neurons, and bath application of 5‐HT reduced the response amplitude with maximum effect at 10 Όm. Local ejection of 5‐HT either onto the RS cells or onto the relay cells decreased sensory‐evoked excitatory postsynaptic potentials (EPSPs) in RS cells. The monosynaptic EPSPs elicited from stimulation of the relay cells were also reduced by 5‐HT. The reduction was maintained after blocking either N‐methyl‐d‐aspartate (NMDA) or α‐amino‐3‐hydroxy‐5‐methylisoxazole‐4‐propionic acid (AMPA) receptors. The local ejection of glutamate over RS cells elicited excitatory responses that were only slightly depressed by 5‐HT. In addition, 5‐HT increased the threshold for eliciting sustained depolarizations in response to trigeminal nerve stimulation but did not prevent them. Combined 5‐HT immunofluorescence with axonal tracing revealed that the 5‐HT innervation of RS neurons of the middle rhombencephalic reticular nucleus comes mainly from neurons in the isthmic region, but also from neurons located in the pretectum and caudal rhombencephalon. Our results indicate that 5‐HT modulates sensory transmission to lamprey brainstem RS cells

    Electron simulated desorption of oxygen and ethylene adsorbed on a Ni[sub0.9]Cu[sub0.1] (111) surface

    Includes bibliographical references (pages 40-41)This thesis represents the first paper generated by the system for electron stimulated desorption (ESD) established at Northern Illinois University. Its major goals are (1) to verify the proper operation of the system and (2) to investigate the interaction of oxygen and ethylene on the surface of a nickel-copper alloy. Evidence is presented that confirms the system's operation. Also presented are the results of the ESD of oxygen and ethylene from a nickel-copper surface. It was observed that ethylene, either alone or coadsorbed with oxygen, had very little effect on desorption as compared to the clean surface. However, oxygen was found to significantly affect the desorption of hydrogen from the surface, suggesting a change in the bond state of hydrogen in the presence of oxygen.M.S. (Master of Science
