Simplicial structures on model categories and functors

We produce a highly structured way of associating a simplicial category to a model category which improves on work of Dwyer and Kan and answers a question of Hovey. We show that model categories satisfying a certain axiom are Quillen equivalent to simplicial model categories. A simplicial model category provides higher order structure such as composable mapping spaces and homotopy colimits. We also show that certain homotopy invariant functors can be replaced by weakly equivalent simplicial, or `continuous', functors. This is used to show that if a simplicial model category structure exists on a model category then it is unique up to simplicial Quillen equivalence.Comment: To appear in American Journal of Mathematic

Assessing Collateral Consequences Accompanying Sex Offender Registration

Sex Offenders are often the most feared group of offenders. In response to this fear, sex offender registries were created as a method for monitoring convicted offenders and for providing communities with a sense of security by publicizing information about potential predators nearby. The underlying questions are whether or not notification and registration laws actually reduce crime and make the community safer. According to the literature, and to the current study, they do not. However, community safety and recidivism rates are not the only factors that pose concern attributed to registration and notification. Researchers alike have argued that these practices are a violation of human rights and the stigma surrounding the label infringes upon the lives of offenders and their family. Therefore, collateral consequences experienced by both offenders and by third parties are a common occurrence. In the current study, nine common themes were identified: impact on employment; impact on housing; perceptions of the registry; mental and emotional health; denial of service excluding housing and employment; impact on families; impact on other relationships; support networks; and vituperative attacks. The same nine themes were used to assess family members. Through each of these themes, an array of collateral consequences were identified that range in severity. In the discussion and conclusion section, reintegration difficulty, myths surrounding stranger danger, and ways in which social capital can be gained are discussed

The impact of a post-take ward round pharmacist on the risk score and enactment of medication-related recommendations

There is a scarcity of published research describing the impact of a pharmacist on the post-take ward round (PTWR) in addition to ward-based pharmacy services. The aim of this paper was to evaluate the impact of clinical pharmacists' participation on the PTWR on the risk assessment scores of medication-related recommendations with and without a pharmacist. This includes medication-related recommendations occurring on the PTWR and those recommendations made by the ward-based pharmacist on the inpatient ward. A pre-post intervention study was undertaken that compared the impact of adding a pharmacist to the PTWR compared with ward-based pharmacist services alone. A panel reviewed the risk of not acting on medication recommendations that was made on the PTWR and those recorded by the ward-based pharmacist. The relationship between the risk scores and the number and proportion of recommendations that led to action were compared between study groups. There were more medication-related recommendations on the PTWR in the intervention group when a pharmacist was present. Proportionately fewer were in the 'very high and extreme' risk category. Although there was no difference in the number of ward pharmacist recommendations between groups, there was a significantly higher proportion of ward pharmacist recommendations in the "very high and extreme" category in those patients who had been seen on a PTWR attended by a pharmacist than when a pharmacist was not present. There were a greater proportion of "low and medium" risk actionable medication recommendations actioned on the PTWR in the intervention group; and no difference in the risk scores in ward pharmacist recommendations actioned between groups. Overall, the proportion of recommendations that were actioned was higher for those made on the PTWR compared with the ward. The addition of a pharmacist to the PTWR resulted in an increase in low, medium, and high risk recommendations on the PTWR, more very high and extreme risk recommendations made by the ward-based pharmacist, plus an increased number of recommendations being actioned during the patients' admission

Findings from the California Youth Transitions to Adulthood Study (CalYOUTH): Conditions of Youth at Age 19

The "CalYOUTH Wave 2 Youth Survey", conducted when the young people participating in CalYOUTH were 19 years old, follows up on a survey of the same young people when they were approaching the age of majority in California's foster care system. More than 80 percent of the youth who took part in the baseline interviews participated in the Wave 2 survey. The report provides the most comprehensive view to date of young adults making the transition to adulthood from foster care in California, highlighting differences between young people participating in extended foster care and young people who had left care. The report provides feedback for all parties interested in improving youth's transitions from foster care to adulthood

Archaeological Data Recovery Of A Burned Rock Midden At Site 41CM412, Comal County, Texas

The Comal Independent School District (CISD) retained Pape-Dawson Engineers, Inc. (PapeDawson) to conduct cultural resource investigations for the proposed construction of a new high school (High School #4) near the city of Garden Ridge in southern Comal County, Texas. The CISD High School #4 Project (Project) includes construction of buildings, parking lots, roadways, and associated utility installation for the new school campus. After the identification of a State Antiquities Landmark (SAL)-eligible burned rock midden at site 41CM412 during the preliminary archaeological survey, a data recovery investigation was undertaken within this portion of the site. Pape-Dawson archaeologists initially identified site 41CM412 during an intensive archaeological survey for the Project between December 11, 2017, and January 10, 2018, under Texas Antiquities Permit No. 8244. Comprising the entire 40.4-hectare (ha; 99.8-acre [ac]) survey area, site 41CM412 is a multi-component site containing early to mid-twentieth century structures, a light scatter of historic artifacts, an extensive scatter of prehistoric lithic material (both tools and non-tools), and a large burned rock midden. While the historic component of the site, as well as the extensive lithic artifact scatter, were determined to be not eligible for designation as a SAL, Pape-Dawson’s survey effort concluded that the burned rock midden demonstrated research value. Following completion of the initial survey, Pape-Dawson archaeologists coordinated with the Texas Historical Commission (THC), who concurred that the burned rock midden feature at site 41CM412 met the requirements for SAL designation. As impacts to the burned rock midden at site 41CM412 could not be avoided during the proposed Project construction, Pape-Dawson archaeologists conducted a data recovery investigation of the midden deposits. Since CISD is a political subdivision of the State of Texas, compliance with the Antiquities Code of Texas (ACT) was required for the investigation. Pape-Dawson completed the data recovery field effort under Texas Antiquities Permit No. 8361 between March 19 and April 3, 2018. The data recovery Project Area included a buffer of 0.66 ha (1.63 ac) surrounding the 0.21-ha (0.51-ac) midden area within the overall 40.4-ha (99.8-ac) site boundary. The primary goals of the investigation were to (1) assess the age or age range of the midden accumulation; (2) identify if the type of burned rock formation was sheet, domed, or annular; (3) identify the fuel sources and types of food processed at the midden; (4) determine if a heating element was present within the midden or if the rocks were heated elsewhere; and (5) determine if the accumulation of burned rock was gradual over a period of time or rapid during a phase of intense usage. To address these research questions, the investigation consisted of a program of systematic shovel testing, mechanical excavation of two archaeological trenches, and the hand-excavation of two 1-x-1-meter (3.3-x-3.3-foot) units, as well as five 50-x-50-centimeter (19.7-x-19.7-inch) columns. Melanie Nichols served as the initial Principal Investigator (PI), and Dr. Karissa Basse assumed responsibility as PI during report production. Field efforts were led by Melanie Nichols, with assistance from Jacob Sullivan, Virginia Moore, Megan Veltri, and Dr. Nesta Anderson. Light Detection and Ranging imaging and drone footage were collected on site by David Leyendecker and Angela Livingston. Geographic Information Systems and laboratory assistance was provided by Jacob Sullivan, Sheldon Smith, Ann Marie Blackmon, and Mikayla Mathews. Curation for the Project was completed by Ann Marie Blackmon and Mason Miller. Special studies, including macrobotanical analysis, faunal analysis, projectile point analysis, magnetic susceptibility testing, and radiocarbon dating, were conducted by Dr. Leslie Bush, Melanie Nichols, Chris Ringstaff, Dr. Charles Frederick, and Direct AMS, respectively. Brooke Bonorden served as editor, and Zachary Overfield oversaw quality control and quality assurance. The data recovery investigations resulted in the horizontal and vertical refinement of the boundaries of the burned rock midden (Feature 1) within 41CM412, which dates to the Archaic period. In addition, two internally embedded features—a possible heating element (Feature 1.1) and an earth oven pit (Feature 1.2)—were identified. A historic-age midden (Feature 2) was also identified during investigation. In total, the prehistoric assemblage collected from site 41CM412 consists of 3,224 prehistoric artifacts, including 3,156 lithics (17 projectile points, 2 dart point preforms, 29 bifaces, 3 unifacial scrapers, 1 perforator, 5 edge-modified flakes, 2 cores, 1 blank, and 3,096 pieces of unmodified debitage), 47 faunal bone fragments, 10 pieces of ocher (21.16 grams [g]), 1,395.4 g burned clay, 2.46 g charcoal, and 2,910 pieces of burned rock (214.29 kilograms). The historic- and modern-age material recovered from the site largely consists of metal, glass, cut faunal bone, and mortar. All cultural material was collected and brought back to the Pape-Dawson Laboratory in Austin for processing and analysis aside from FCR, which was analyzed and discarded in the field. Based on the results of the fieldwork and subsequent analyses, the burned rock midden at site 41CM412 appears to have largely resulted from a series of long-term, or perhaps seasonal occupations occurring from the Early to Transitional Archaic periods, with a concentrated occupation evident during the Middle Archaic. The vertical distribution of artifacts at the site points to multiple occupations occurring on a landform with a slow sedimentation rate. Integral heating elements and earth oven pits (Features 1.1 and 1.2, respectively) within the Feature 1 midden suggest the site contained a center-focused cooking facility. This facility is represented by the annular formation of the overall midden and on-site heating of the rocks. Task specific activities at the site include earth oven baking (as evidenced by burned rock midden deposits) and tool manufacturing and maintenance (as evidenced by a high percentage of small, tertiary flakes within the artifact assemblage). Processing of predominantly meat products also occurred at the site, given the presence of faunal bone within the overall Feature 1 matrix and general lack of packing material in the earth oven. Ancient fuel sources appear to be hardwoods of oak and potentially juniper. In addition, trace evidence of hickory/walnut/pecan family nuts indicate these plants may have also been processed as a food source. Although not all cultural components of the site were stratigraphically discrete, the burned rock midden deposits illustrate evidence of use and reuse over several millennia. This sequence significantly contributes to our understanding of Archaic cooking models and burned rock formation processes. In accordance with the criteria in 13 ACT 26.10, Pape-Dawson’s data recovery of the SAL eligible portion of site 41CM412 has mitigated any impact associated with the construction of the Comal ISD High School #4. As a result, Pape-Dawson recommends no further work for the site. The THC concurred with the Pape-Dawson’s recommendation on April 13, 2018 and allowed construction for the Project to proceed. Furthermore, Pape-Dawson received concurrence from the THC for the draft report of investigation on October 23, 2020. Following completion of the final report, artifact discard decisions will be coordinated with the THC. Project records, photographs, and select collected artifacts will be curated at the University of Texas at San Antonio Center for Archaeological Research

Northeast Ocean Planning Baseline Assessment: Marine Resources, Infrastructure, and Economics

This document summarizes the status of coastal and marine resources in the Northeast region of the United States, and how these resources generate economic and ecological value. The Northeast region, for ocean planning purposes, includes the coastal counties of Maine, New Hampshire, Massachusetts, Rhode Island, and Connecticut, and the New York counties (bordering Long Island Sound) of Queens, Bronx, Suffolk, Nassau, and Westchester. The coastal and marine natural resources and coastal infrastructure of the Northeast, and the economic activities and cultural/recreational services that rely them, directly and indirectly support more than 500,000 jobs and $40 billion in economic value (GDP) per year (2013 data) in the region. This represents about 2% of the region’s overall economy. In addition, US Navy and Coast Guard activities in the region support more than 10,000 jobs and account for billions of dollars per year in federal expenditures in the region. The region’s coastal and ocean resources also generate significant ecosystem service value in the region and beyond, though these values are not well quantified. Coastal and marine recreation and tourism account for about half of the region’s ocean economy GDP and for more than 70% of ocean economy employment. The maritime transportation sector account for 16% of ocean economy employment and 29% of ocean economy GDP in the region; ship and boat building accounts for 11% of employment and 13% of GDP; and commercial fisheries and seafood processing account for 6% of employment and 8% of GDP. Information about the spatial distribution and status of coastal and marine resources and the economic activities that make use of them inform and support the Northeast ocean planning process

Nothing to hide: An X-ray survey for young stellar objects in the Pipe Nebula

We have previously analyzed sensitive mid-infrared observations to establish that the Pipe Nebula has a very low star-formation efficiency. That study focused on YSOs with excess infrared emission (i.e, protostars and pre-main sequence stars with disks), however, and could have missed a population of more evolved pre-main sequence stars or Class III objects (i.e., young stars with dissipated disks that no longer show excess infrared emission). Evolved pre-main sequence stars are X-ray bright, so we have used ROSAT All-Sky Survey data to search for diskless pre-main sequence stars throughout the Pipe Nebula. We have also analyzed archival XMM-Newton observations of three prominent areas within the Pipe: Barnard 59, containing a known cluster of young stellar objects; Barnard 68, a dense core that has yet to form stars; and the Pipe molecular ring, a high-extinction region in the bowl of the Pipe. We additionally characterize the X-ray properties of YSOs in Barnard 59. The ROSAT and XMM-Newton data provide no indication of a significant population of more evolved pre-main sequence stars within the Pipe, reinforcing our previous measurement of the Pipe's very low star formation efficiency.Comment: Accepted for publication in Ap
