The Mouth Parts of the Firebrat Thermobia domestica (Packard), (Thysanura)

The purpose of this paper is to present detailed drawings of the external form of the mouth parts of the adult firebrat, as a representative lepismatid. That the Lepismatidae, or silverfish insects, are of great significance in insect morphology, is well known to students of the subject. In certain respects they are the principle morphological link between the Apterygota and the Pterygota. While any of the widely distributed, domestic species of Lepisma or Ctenolepisma might well be used for morphological study, the firebrat, Thermobia domestica, is the species which seems to us the most likely to be practical for use in experimental biology, largely because it is thermophilic and can be reared comparatively quickly at high constant temperatures (Adams, HJ33, 1936; Sweetman, 1938). This insect has been used successfully in a series of toxicological studies carried on at Iowa State College: one of the more recent of these is an investigation of the toxicity of barium compounds (Richardson and Seiferle, 1941). The morphology of this insect, including the structure of its mouth parts, is likely to be of interest to a considerable variety of workers

Responses from the Field

DeFiore (2006) provides a comprehensive review of elements that have shaped the state of special education in Catholic schools. The article speaks of the bishops’ vision without teeth and the theoretical support provided under the Individuals with Disabilities Education Improvement Act of 2004 (IDEIA). DeFiore discusses the demand for services that are not met because of a lack of resources, expertise, and funding. The article concludes by allowing that much has occurred over the past decade, but more is needed. To meet this need, DeFiore states that diocesan and local leaders must face the challenge of inspiring the laity to respond to this need with the necessary enthusiasm. We believe that high quality special education comes out of a culture of inclusiveness and is not impacted as greatly by resources as DeFiore and others would suggest. The focus on the inequities in funding between public and private schools often provides an opportunity to justify the inability to provide services for children with special needs. In truth, special education is mandated but not fully funded in public schools as well. At the time that the original special education act, Education for All Handicapped Children Act of 1975, was signed into law, President Ford warned that the mandates would far exceed the allocated resources. His hope was that Congress would revise the law to be more realistic before it was enacted in 1978. These revisions never happened and the mandates of the law continue to exceed the funding (Freedman, Bisbicos, Jentz, & Orenstein, 2005)

An Integrated Approach to Paleo-Ice Stream Determination in Mid Continental Prairies, Saskatchewan, Canada

Ice stream research has gained momentum in the last decade due to the increased need to understand ice sheet dynamics and instability and, by extension, the role ice streams have on climate change and sea level rise. Although significant progress has been made recently in understanding the role of ice streams in ice sheet dynamics, much remains to be done for documenting and understanding paleo-ice stream records. This is especially true for terrestrial paleo-ice streams like those that operated in the southwest Laurentide Ice Sheet. In previous studies evidence was shown for at least two large paleo-ice stream systems in southern Saskatchewan and a model was proposed involving major glacial dynamics shifts during the Late Wisconsinan linked to ice streaming in the Prairies. The goal of this research is to further characterize drift provenance and to verify sediment-landform assemblages that are central to the proposed reconstruction. This is done through spatial analysis of sediment and landform characteristics (e.g. compositional data, till fabric, landform identification). Provenance is also investigated using radiometric data and 40Ar/39Ar dating of hornblende grains. All of the data are geo-referenced in GIS to examine the spatial relationships. Results show spatially consistent patterns that fit within the structure of the proposed ice stream model. Ten assemblages were delineated, some showing landform evidence of southwestern and southeastern flow, while others show an older western signature through compositional data. The ice flow dynamics were characterized by a combination of landform evidence and compositional data, where three distinct ice flow phases can be seen. Of these three flow phases, two can be characterized by paleo-ice streams. The older south westward Maskwa system flowed against the regional slope, creating a large area of mega-scale glacial lineations, as well as transverse ridges, and was bound on either side by hummocky terrain. The preservation of the southwest Maskwa system was due to the abrupt shift to the southeastward Buffalo system. The Buffalo system captured the subglacial water from the Maskwa causing its shutdown, which fed the James Lobe until it collapsed. The Buffalo paleo-ice stream was the youngest and least stable of the two systems, as shown in the cross-cutting landform evidence. This approach combines multiple methods of analysis to go beyond the geomorphologic evidence to test the main underlying assumptions of paleo-ice stream landsystem models. This is critical if we are to understand the processes involved in the formation of paleo-ice streams and to reconstruct their evolution. Further characterization of the paleo-ice stream systems in the Prairies is critical to improve our understanding of how large ice sheets, like the Laurentide Ice Sheet, evolved and eventually collapsed
