Habitat Use, Distribution, and Density of Dwarf Seahorse (Hippocampus zosterae) Populations along the Texas Gulf Coast
Get PDFThe Dwarf Seahorse (Hippocampus zosterae) is one of the smallest species of seahorse and resides in shallow waters throughout the Gulf of Mexico, Atlantic Coast of Florida, and Caribbean. They rely on seagrass beds for feeding, spawning, and refuge, rarely traveling far from the bed in which they were spawned. Information on density, distribution, and habitat associations in Texas are needed to address knowledge gaps and inform future management initiatives. We evaluated seagrass beds along the Texas Coast (from Galveston Bay to the Lower Laguna Madre) to determine what factors correlated with Dwarf Seahorse presence and density. Dwarf Seahorse (n=79) were captured at 30 of 80 (36.3%) sites. They were detected in all sampled bay systems except Galveston Bay. Dwarf Seahorse were found in association with all seagrass species found in Texas. Variables significantly correlated with Dwarf Seahorse presence included average seagrass biomass, turtle grass (Thalassia testudinum) percent cover, and nekton species abundance, evenness, and richness. Variables significantly correlated with Dwarf Seahorse density included number of seagrass species present, the presence of turtle grass, and nekton species evenness, and richness. Nekton species associated with the presence of Dwarf Seahorse included grass shrimp (Palaemonetes spp.), Penaeid shrimp, Code Goby (Gobiosoma robustum), and Rainwater Killifish (Lucania parva). There were an estimated 1,116,356 Dwarf Seahorse in Aransas Bay, 2,769,686 in Upper Laguna Madre, and 7,899,652 in Lower Laguna Madre throughout the sampling time frame. Results from this study will inform continued monitoring, development of a habitat suitability index, and management of this species and their essential habitat
Inventory of Silveira Files
Get PDFThe Silveira files are divided into five sections. The first section contains subject files which have been maintained in the order received and filed alphabetically by folder title. The subject files are followed by reports arranged chronologically, after which are chronologically filed presentations. Following presentations are miscellaneous chronological files, and finally graphics - photographs and viewgraphs
Inventory of Solar Max Documents
Get PDFThese documents were collected by Gerald P. Kenney of the Payload Integration Office (mail code LP). They range in date from 1977 to 1984 and consist of correspondence, presentations and reports related to the Solar Max Repair Mission. They are arranged in two categories. The first is a chronological run of documents generally related to the Solar Max Repair Mission (SMRM). This section is followed by material organized primarily by subject. These subjects relate to issues involved with the Solar Max Repair Mission such as the remote manipulator system (RMS) foot restraint (MFR), SMRM safety issues, and the flight support system (FSS). The last box contains the interface control document (ICD), console log, and Mr. Kenney's workbook
Examining Executive Functioning in Children with Externalizing and Internalizing Behaviors Using the BRIEF2
Get PDFMany children struggle with externalizing and internalizing behaviors, with some reaching diagnosable levels. Research has suggested these children also have significant difficulty with executive functioning. The BRIEF is a behavior observation narrowband rating scale that is frequently used to identify executive dysfunction in children. However, with the new standardization of the BRIEF2, there is no research to date that uses this measure to identify executive dysfunction in children with externalizing and internalizing behaviors. The purpose of this study was to examine the use of the BRIEF2 teacher form for investigating the relation between externalizing and internalizing behaviors and executive functioning. Standardization data provided by the authors of the BRIEF2 were used for this study. Teachers of the subjects provided data regarding the subjects’ externalizing and internalizing behaviors using the BASC-2, as well as the subjects’ executive functioning abilities using the BRIEF2. Increases in domains of executive functioning were found to be significantly associated with behavior. Given that externalizing and internalizing behaviors are related to executive functioning, the current study provided further evidence that this relation is important, and the BRIEF2 may be considered an appropriate measure for this purpose
Inventory of STS-51-L Mission Documents
No full textOnly the first few documents in this subseries are those that are found in most other flight related documents subseries for the STS-51 mission, more commonly known as the Challenger explosion. The press kit, flight plan and flight rules are included, but other than that the bulk of the documentation was created after the accident and geared towards return to flight, reaction to the accident and response to the Presidential Commission investigating the 51-L accident. Also included in this subseries are two videotapes of the 51-L memorial service. This subseries is geared toward looking at only issues related to this flight and its impact on future flights. For information on the investigation proper see the 51-L investigation subseries. Some files about the accident can also be found in the Charlesworth files in the Center collection. The documentation is arranged chronologically and dated from 1984 through 1988 and responding to the "Report off the Presidential Commission on the Space Shuttle Challenger Accident." The video tapes of the memorial service are at the end of the run, in box 6

Secondary Co-Teachers’ Perceptions of Their Competence in Co-Teaching and Utilizing Integrative Technology
No full textWhen ensuring the least restrictive environment for students eligible and receiving special education services a delivery option frequently considered is providing a second teacher in the general education classroom. This second teacher is often a specialist in special education instruction which allows for an increase in opportunities for differentiation and specially designed instruction through the instructional model known as co-teaching. Related, instruction is increasingly being presented through integrative technology. The purpose of this study was to explore secondary educators’ perceptions of their competence in co-teaching and utilizing integrative technology, and the relationship it has with educators’ perceived practices. The findings from this study illustrated the illusion of beliefs and knowledge and emphasized the disconnect between knowledge and classroom practice. Several misconceptions of co-teaching and integrative technology are presented within this study’s findings
The perspectives of secondary math and science teachers, administrators, and district personnel on retaining highly qualified secondary math and science teachers in Title I districts
No full textThe purpose of this study was to explore the perceptions of urban secondary math and science teachers, administrators, and district personnel regarding the factors that influence secondary math and science teachers with more than five years of teaching experience to remain in urban Title I districts. The participants were interviewed to gain their perspective of teacher retention through their experiences and roles in the district. The participants discussed: (a) the lack of preparation to teach in urban schools, (b) why teachers leave urban districts, and (c) what districts can do to retain teachers. The outcome of this study is to positively impact teacher retention of secondary math and science teachers in urban districts by selecting teachers who have a desire to work with at-risk students, continuously have a growth mindset, and have students achieve academic success
