This article explores the definition of Critical Autism Studies and its inclusion in autistic scholarship. There has been critique of recent non-autistic literature for lacking autistic authorship, leading to doubts about its epistemological integrity due to misrepresentations of autistic culture and the neurodiversity movement. This article utilises the work of Arnold, Milton and O'Dell et al. to introduce an emancipatory definition to ensure the discipline is autistic led. In the process, we discuss the nature of autism studies and what constitutes critical literature. We propose Waltz's interpretation of Critical Autism Studies as a working definition.

The dominant discourse in Autism since the first appearance of the word in the psychiatric literature, has been what has subsequently been called the Medical Model [1] but in recent times there have been many challenges drawing from the field of disability studies and the emerging field of critical autism studies. This is the story of how I came to start Autonomy, the Critical Journal of Interdisciplinary Autism Studies [2]. I did not discover my autism-I prefer the word discovery over diagnosis-during the lifetime of either of my parents. I had not felt any great need for an identity whilst they were still alive and put off many questions I perhaps ought to have addressed whilst they were still there to answer them. I had been long aware that I related to the world in a very particular way, when I watched others around me as I grew up, negotiate the world with an apparent ease that was foreign to me. In my mid-twenties I took L. Arnold (B)

The east side of the Uncompahgre River Basin has been a known contributor of dissolved selenium to recipient streams. Discharge of groundwater containing dissolved selenium contributes to surface-water selenium concentrations and loads; however, the groundwater system on the east side of the Uncompahgre River Basin is not well characterized. The U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board and the Bureau of Reclamation, has established a groundwater-monitoring network on the east side of the Uncompahgre River Basin. Ten monitoring wells were installed during October and November 2012. This report presents location data, lithologic logs, well-construction diagrams, and well-development information. Understanding the groundwater system will provide managers with an additional metric for evaluating the effectiveness of salinity and selenium control projects.

The Kiowa core was obtained as a component of the Denver Basin Project, a cooperative research effort to study the evolution of the Denver Basin, Colorado. The Kiowa core provides a virtually continuous stratigraphic record of the Upper Cretaceous and lower Tertiary strata of the Denver Basin. The upper portion of the core recovered strata conventionally referred to as the Arapahoe and Denver Formations and the Dawson Arkose. A prominent unconformity marked by a mature paleosol breaks these strata into two unconformity-bounded sequences; the lower sequence is termed D1 and the upper sequence, D2. Beneath these units and also penetrated by the core occur the Laramie Formation, Fox Hills Sandstone, and Pierre Shale. The site for coring was selected in order to obtain fine-grained strata suitable for both palynological and paleomagnetic analyses. The coring effort recovered 93 percent of the 2,256 ft of rock penetrated, resulting in a nearly continuous record of the sedimentary rocks recording the retreat of the Cretaceous Interior Seaway and the subsequent uplift of the Front Range portion of the Rocky Mountains. Palynological data constrain the Cretaceous-Tertiary boundary to a depth between 878 and 880 ft in the core. The palynological data also serve to bracket the age of the paleosol marking the unconformity between the D1 and D2 sequences to between middle Paleocene and earliest Eocene. The paleomagnetic data are interpreted to represent polarity intervals ranging from polarity subchrons 31r to 28n and polarity subchron 24r. Hydrologic analyses indicate variable aquifer characteristics across the State-defined bedrock aquifers. Individual aquifer units exhibit generally lower water-yield potential than was identified to the west in a core drilled by the U.S. Geological Survey (USGS) in 1987 at Castle Pines, Colorado. Downhole temperature measurements indicate a normal geothermal gradient of 30°C/ km. Perturbations of the gradient may represent active fluid flow through the aquifers penetrated by the core. Petrographic examination of the cored sandstone and mudstone units document both the clayrich character of the paleosol series marking the boundary between the D1 and D2 sequences, and variation in sandstone composition with depth. The lower sequence (D1) is characterized by litharenites with a significant volcaniclastic component, while the upper sequence (D2) is more arkosic. Extensive lignite beds occur in D1 in the cored interval and these appear as strong reflectors on the seismic line that passes near the core hole. A set of electric logs, core descriptions, and derived data sets accompany this report.

Computational experiments with the primal integer programming algorithm indicate that in many cases the optimal value of the objective function is obtained in a very few iterations but a large number of iterations are required to establish optimality; thus, an alternative proof of optimality is needed. This paper describes an algorithm for obtaining an upper bound (such an alternative) on the value of the objective function. This bound is based on the best bound obtainable from dual solutions to a class of related linear programs. Computational results illustrating the effectiveness of this bounding technique are presented.
