Squeezing minds from stones: Cognitive archaeology and the evolution of the human mind

Cognitive archaeology is a relatively new interdisciplinary science that uses cognitive and psychological models to explain archaeological artifacts like stone tools, figurines, and art. Edited by cognitive archaeologist Karenleigh A. Overmann and psychologist Frederick L. Coolidge, Squeezing Minds From Stones is a collection of essays, from both early pioneers and 'up and coming' newcomers in the field, that addresses a wide variety of cognitive archaeology topics, including the value of experimental archaeology, primate archaeology, the intent of ancient tool makers, and how they may have lived and thought

The Infection Dynamics of Sea Lice on Atlantic Salmon (Salmo Salar) in Cobscook Bay, Maine, USA

Sea lice (Lepeophtheirus and Caligus spp) are parasitic copepods that infect the external surfaces of fish hosts. Salmon lice (L. salmonis) outbreaks are commonly reported by operations in Canada, Norway, Scotland, Ireland, and the United States and are a primary concern in aquaculture because of their fish health and economic impacts. When farmed fish mortalities and treatments are accounted for, annual losses from sea louse infestations exceed $300,000,000 (Costello 2009). Farms experiencing sea lice infections risk on-site re-infection and transmission to wild populations and other farms that are hydrographically connected. In Maine, Atlantic salmon farms are located in the northeast, with major operations in Machiasport and Cobscook Bay. The primary aim of this study was to establish the infection dynamics of sea lice in Cobscook because it is positioned at the mouth of the Bay of Fundy, where outbreaks are increasingly common but are not well described in the available literature. Sentinel cages housed Atlantic salmon juveniles for a total of 7 days every month to monitor sea lice settlement at 4 sites within Cobscook Bay: Broad Cove, Comstock Cove, Prince Cove, and Pembroke Landing. The survey revealed a pre-season (early summer) and season (autumn) peak for sea lice prevalence (percent infected fish) and abundance (lice/fish). Spatial differences in prevalence and abundance were also detected for most months of the study and Pembroke Landing became a site of interest because the observed infection trends were unique relative to the remaining coves. Copepodid and chalimus stages were not detected in the late winter or early spring in 2014 because temperatures were not supportive of egg hatching, naupliar survival, or copepodid attachment. The source of the infections observed over the course of 18 months was unclear and farm counts from the time of the study were not made available for farm to sentinel comparisons. The relationship between environmental factors and total sea lice counts were investigated using generalized linear mixed effect models (GLMMs) with a negative binomial distribution and a log link function. A mathematical model estimating body surface area of Atlantic salmon juveniles was designed and then used to generate fish morphometric data for GLMM development. Data from individual sites were initially pooled to generate a general model for the entire bay, but the significance of Pembroke Landing as an individual site prompted a need to generate site-specific GLMMs. Temperature had a positive relationship on total sea lice count at all sites, which was expected because of its biological relevance in expediting sea louse development and growth. Current velocity had a negative relationship with sea lice at Prince Cove and Pembroke Landing, likely because average velocities were within a range that limits sea lice attachment. Results from the survey and the mathematical model were linked with previous work on sea lice infection dynamics to develop scenarios that describe potential sources of infection for Cobscook Bay. These data and scenarios will be used to inform future bio-physical models and assist in developing hypotheses that can be tested once models are validated and confirmed

Evaluation of 2007 Montana crash data reported to the Motor Carrier Management Information System Crash File

This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associated with reporting rates for the State of Montana. MCMIS Crash File records were matched to the Montana crash file to determine the nature and extent of underreporting. It is estimated that that Montana reported 81.0 percent of reportable crash involvements in 2007. Reporting rates were found to be related to crash severity, the configuration of the vehicle, and the type of enforcement agency that covered the crash. Over 97 percent of fatal crash involvements were reported, 80.2 percent of injury/transported involvements, and 80.2 percent of towed/disabled involvements. Trucks were reported at a significantly higher rate than buses. Large trucks, especially truck tractors, were reported at a higher rate than smaller trucks. Missing data rates are low for most variables. Corresponding data elements in the MCMIS and Montana crash files were reasonably consistent, though specific problems were noted with respect to some variables. The timeliness of report was outstanding, with almost 99 percent of records submitted to the MCMIS file within 90 days of the crash.Federal Motor Carrier Safety Administrationhttp://deepblue.lib.umich.edu/bitstream/2027.42/89596/1/102788.pd

Evaluation of 2008 Rhode Island crash data reported to the Motor Carrier Management Information System Crash File

This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associated with reporting rates for the State of Rhode Island. MCMIS Crash File records were matched to the Rhode Island crash file to determine the nature and extent of underreporting. It is estimated that that Rhode Island reported 75.0% of reportable crash involvements in 2008. The most decisive factor identified in predicting reporting was whether the Truck/Bus Crash Report Supplemental form was completed. Over 95% of reportable cases with this form completed were reported, compared with no records where the officer did not fill out the form. Missing data rates are low for most variables. Corresponding data elements in the MCMIS and Rhode Island crash files were reasonably consistent, though specific problems were noted with hazmat variables and the truck and trailer configuration.Federal Motor Carrier Safety Administrationhttp://deepblue.lib.umich.edu/bitstream/2027.42/89601/1/102793.pd

Evaluation of 2009 New York Crash Data Reported to the Motor Carrier Management Information System Crash File

This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associated with reporting rates for the State of New York. MCMIS Crash File records were matched to the New York crash file to determine the nature and extent of underreporting. Because all levels of the MCMIS crash file reporting criteria could not be applied, the evaluation of reporting completeness was restricted to crashes that involved either a fatality or an injury transported for immediate medical attention. Of these crashes, an estimated 36.7 percent were properly reported. Reporting rates were found to be related to crash severity and the configuration of the vehicle. Over 82 percent of fatal crash involvements were reported, but only 34.6 percent of injury/transported involvements. Crashes in which a vehicle was towed due to disabling damage could not be identified in the New York crash data supplied, so reporting rates for that subset cannot be estimated. Trucks were reported at a slightly higher rate than buses. Large trucks, especially truck tractors, were reported at a higher rate than smaller trucks. Missing data rates are low for most variables. Corresponding data elements in the MCMIS and New York crash files were quite consistent, though specific problems were noted with respect to one truck configuration. The timeliness of reporting was good, with about 91 percent of records submitted to the MCMIS file within 90 days of the crash.Federal Motor Carrier Safety Administrationhttp://deepblue.lib.umich.edu/bitstream/2027.42/89602/1/102794.pd

Evaluation of 2008 Alaska crash data reported to the Motor Carrier Management Information System Crash File

This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associated with reporting rates for the State of Alaska. MCMIS Crash File records were matched to the Alaska crash file to determine the nature and extent of underreporting. It is estimated that Alaska reported 62.4 percent of this subset of reportable crash involvements in 2008. Reporting rates were found primarily to be related to crash severity and the configuration of the vehicle. Eighty percent of fatal crash involvements were reported, 73.9% of injured/transported, and 58.7 percent of towed/disabled involvements. Trucks were reported at about the same rate as buses as a whole, 61.4% to 66.0%. Large trucks such as tractor-semitrailers were reported at a higher rate than smaller single unit trucks. Missing data rates are low for most variables. Corresponding data elements in the MCMIS and Alaska crash files were reasonably consistent,Federal Motor Carrier Safety Administrationhttp://deepblue.lib.umich.edu/bitstream/2027.42/89599/1/102791.pd

Evaluation of 2010 Delaware crash data reported to the Motor Carrier Management Information System Crash File

Special reportThis report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associated with reporting rates for the State of Delaware. MCMIS Crash File records were matched to the Delaware crash file to determine the nature and extent of underreporting. Overall, it is estimated that, for 2010, 71.6% of reportable crash involvements were reported. All fatal crash involvements were correctly reported. Reporting rates were lower for less severe collisions: 66.6% of injured/transported crashes and 76.6% of towed/disabled crashes were reported. Recognition by the reporting officer that a vehicle was a CMV was important, though no single factor was identified that explained the overall reporting rate. Missing data rates are low for most variables. Corresponding data elements in the MCMIS and Delaware crash files were reasonably consistent, though specific problems were noted with respect to the MCMIS truck configuration variable. Over one-quarter of the records were inconsistent on this variable. Improvements in training to may address this issue. Only about 53 percent of records were submitted to the MCMIS file within 90 day post-crash period requirement.Federal Motor Carrier Safety Administrationhttp://deepblue.lib.umich.edu/bitstream/2027.42/90844/1/102853.pd
