Excavations at the Bluff Creek Sites: 41MK10 and 41MK27, McColloch County, Texas

From late 1978 through early 1979, Ann M. Irwin of the Texas Department of Transportation (TxDOT) supervised excavations of two prehistoric archeological sites, 41MK10 and 41MK27, that were to be affected by construction along FM 765 in McCulloch County, Texas. The sites are located on Bluff Creek in the northern part of McCulloch County. Analyses of sites 41MK10 and 41MK27 and their cultural materials were conducted by TxDOT personnel in 1979, and an initial draft form of the report was prepared by Irwin in the early 1980s. TxDOT subsequently contracted SWCA, Inc. Environmental Consultants in 1999 to complete the report of the results of archeological investigations at 41MK10 and 41MK27 and to prepare the artifacts and records for curation. Site 41MK27 contained a small burned rock midden, Feature I. This midden was approximately 8 to 10 m in diameter, and 50 cm thick, and annular in form. A single internal feature (Feature IA), a rock-lined pit or hearth, was located in the approximate center and bottom of the midden. Lying between the midden and Bluff Creek were a series of small hearths, of which eight were excavated and designated as Features III through X. These small hearths, most of which had been at least somewhat disturbed, appeared to have been simple structures composed of one or more layers of rock. Many of the individual rocks appear to have been fire-fractured in place. No true basin-shaped hearths were observed. Associated with these hearths were an accompanying scatter of living debris in the form of flint and burned rock and significant quantities of freshwater mussel shell. Although the individual specimens are relatively small, the quantities recovered suggest that they served as a source of food. Radiocarbon data suggest that the site was intermittently occupied from the Late Archaic through the Late Prehistoric. The midden apparently dates to the Late Prehistoric, although the Transitional Archaic period may have been the period of most intense occupation at the site. Site 41MK10 was smaller than 41MK27 and not as intensively investigated. Two small burned rock features were excavated. The site was at least visited in the Late Archaic times, as is evidenced by the presence of a Castroville point, and in the Transitional Archaic, indicated by the recovery of two Ensor projectile points. It is likely, though by no means firmly established, that these dart point types are in fact associated with the use of the features

Outcomes following child welfare services: What are they and do they differ for Black children?

Current calls to end structural racism in the US include proposals to abolish or radically transform child welfare services (CWS). While substantial research finds numerous poor outcomes following maltreatment, the efficacy and acceptability of CWS, particularly for children of color, has long sparked debate. This review summarizes the state of quantitative research across seven domains for children overall and by race with varying degrees of CWS contact. Current research with adequate comparisons provides no robust evidence to support the idea that children have worse outcomes from CWS involvement, but few studies focused on Black children. Implications for research and system change are discussed

The Stark Implications of Abolishing Child Welfare: An Alternative Path Toward Support and Safety

Scholars and advocates are at odds about how to achieve higher levels of child safety and permanency. Calls for change include the recent upEND focus on eradication of child welfare services to a radical refocusing of the present system towards prevention/early intervention. To clarify the implications of reform over abolition, we seek to portray a future in which the abolition of child welfare has occurred, in juxtaposition to maintaining four core elements of established child maltreatment programmes around the world: (1) receiving and responding to community signals about the risk to children; (2) assessment of need coupled with a proportionate response; (3) rights protections to ensure fairness when placement outside the family is required; and (4) procedures for accountability and quality improvement. For each of these functions, we outline abolitionist advocates\u27 positions and implications for children and parents. Across these elements, we delineate how assigning these responsibilities to communities, as suggested by upEND, would likely (1) exaggerate racial and economic inequities and (2) create structural barriers that would increase harm to children. We suggest several evidence-informed enhancements to practice, research and policy that would mitigate these inequities while also increasing safety and permanency

Structured on-the-job training to improve retention of newborn resuscitation skills: a national cohort Helping Babies Breathe study in Tanzania

Background: Newborn resuscitation is a life-saving intervention for birth asphyxia, a leading cause of neonatal mortality. Improving provider newborn resuscitation skills is critical for delivering quality care, but the retention of these skills has been a challenge. Tanzania implemented a national newborn resuscitation using the Helping Babies Breathe (HBB) training program to help address this problem. Our objective was to evaluate the effectiveness of two training approaches to newborn resuscitation skills retention implemented across 16 regions of Tanzania. Methods: An initial training approach implemented included verbal instructions for participating providers to replicate the training back at their service delivery site to others who were not trained. After a noted drop in skills, the program developed structured on-the-job training guidance and included this in the training. The approaches were implemented sequentially in 8 regions each with nurses/ midwives, other clinicians and medical attendants who had not received HBB training before. Newborn resuscitation skills were assessed immediately after training and 4–6 weeks after training using a validated objective structured clinical examination, and retention, measured through degree of skills drop, was compared between the two training approaches. Results: Eight thousand, three hundred and ninety-one providers were trained and assessed: 3592 underwent the initial training approach and 4799 underwent the modified approach. Immediately post-training, average skills scores were similar between initial and modified training groups: 80.5 and 81.3%, respectively (p-value 0.07). Both groups experienced statistically significant drops in newborn resuscitation skills over time. However, the modified training approach was associated with significantly higher skills scores 4–6 weeks post training: 77.6% among the modified training approach versus 70.7% among the initial training approach (p-value \u3c 0.0001). Medical attendant cadre showed the greatest skills retention. Conclusions: A modified training approach consisting of structured OJT, guidance and tools improved newborn resuscitation skills retention among health care providers. The study results give evidence for including on-site training as part of efforts to improve provider performance and strengthen quality of care

Racial/ethnic differences in Child Protective Services reporting, substantiation, and placement, with comparison to non-CPS risks and outcomes: 2005—2019

We used National Child Abuse and Neglect Data System and Census data to examine Black–White and Hispanic–White disparities in reporting, substantiation, and out-of-home placement both descriptively from 2005–2019 and in multivariate models from 2007–2017. We also tracked contemporaneous social risk (e.g., child poverty) and child harm (e.g., infant mortality) disparities using non-child protective services (CPS) sources and compared them to CPS reporting rate disparities. Black–White CPS reporting disparities were lower than found in non-CPS risk and harm benchmarks. Consistent with the Hispanic paradox, Hispanic–White CPS reporting disparities were lower than risk disparities but similar to harm disparities. Descriptive and multivariate analyses of data from the past several years indicated that Black children were less likely to be substantiated or placed into out-of-home care following a report than White children. Hispanic children were slightly more likely to be substantiated or placed in out-of-home care than White children overall, but this difference disappeared in multivariate models. Available data provide no evidence that Black children were overreported relative to observed risks and harms reflected in non-CPS data. Reducing reporting rates among Black children will require addressing broader conditions associated with maltreatment

Metacognitive beliefs, beliefs about voices and affective symptoms in patients with severe auditory verbal hallucinations

Objectives. This study explores associations between metacognitive beliefs and beliefs about voices in patients with severe auditory verbal hallucinations, and their hypothesized relationship with levels of depression and anxiety. Furthermore, it was hypothesized that metacognitive beliefs are better able to explain differences in levels of depression and anxiety, than beliefs about voices. Design. Cross-sectional data were obtained from baseline measurements of a randomized controlled trial. All patients (N = 77) met the criteria for a DSM-IV diagnosis within the schizophrenia spectrum. A correlation analysis was conducted to explore the associations between metacognitive beliefs and beliefs about voices. Regression analysis was performed to test the second hypothesis. Method. Metacognitive beliefs were measured using the MCQ-30. Beliefs about voices were measured using the BAVQ-R. Furthermore, the Beck Depression Inventory-II and the Beck Anxiety Inventory were applied to measure depression and anxiety. All analyses were a priori controlled for gender and level of education. Results. Significant associations were found between negative beliefs about voices and negative metacognitive beliefs. One of the metacognitive beliefs, that is, perceived uncontrollability and danger of thinking, proved to be a key variable in explaining differences in levels of depression and anxiety and seemed to have greater explanatory value than all of the beliefs about voices when analysed simultaneously. Conclusions. The results offer modest support to models emphasizing the fact that metacognitive beliefs are a core feature in the development and maintenance of depression and anxiety in patients with severe auditory verbal hallucinations. © 2012 The British Psychological Society

Operationalizing marketable blue carbon

The global carbon sequestration and avoided emissions potentially achieved via blue carbon is high (∼3% of annual global greenhouse gas emissions); however, it is limited by multidisciplinary and interacting uncertainties spanning the social, governance, financial, and technological dimensions. We compiled a transdisciplinary team of experts to elucidate these challenges and identify a way forward. Key actions to enhance blue carbon as a natural climate solution include improving policy and legal arrangements to ensure equitable sharing of benefits; improving stewardship by incorporating indigenous knowledge and values; clarifying property rights; improving financial approaches and accounting tools to incorporate co-benefits; developing technological solutions for measuring blue carbon sequestration at low cost; and resolving knowledge gaps regarding blue carbon cycles. Implementing these actions and operationalizing blue carbon will achieve measurable changes to atmospheric greenhouse gas concentrations, provide multiple co-benefits, and address national obligations associated with international agreements

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Utilisation of an operative difficulty grading scale for laparoscopic cholecystectomy

Background A reliable system for grading operative difficulty of laparoscopic cholecystectomy would standardise description of findings and reporting of outcomes. The aim of this study was to validate a difficulty grading system (Nassar scale), testing its applicability and consistency in two large prospective datasets. Methods Patient and disease-related variables and 30-day outcomes were identified in two prospective cholecystectomy databases: the multi-centre prospective cohort of 8820 patients from the recent CholeS Study and the single-surgeon series containing 4089 patients. Operative data and patient outcomes were correlated with Nassar operative difficultly scale, using Kendall’s tau for dichotomous variables, or Jonckheere–Terpstra tests for continuous variables. A ROC curve analysis was performed, to quantify the predictive accuracy of the scale for each outcome, with continuous outcomes dichotomised, prior to analysis. Results A higher operative difficulty grade was consistently associated with worse outcomes for the patients in both the reference and CholeS cohorts. The median length of stay increased from 0 to 4 days, and the 30-day complication rate from 7.6 to 24.4% as the difficulty grade increased from 1 to 4/5 (both p < 0.001). In the CholeS cohort, a higher difficulty grade was found to be most strongly associated with conversion to open and 30-day mortality (AUROC = 0.903, 0.822, respectively). On multivariable analysis, the Nassar operative difficultly scale was found to be a significant independent predictor of operative duration, conversion to open surgery, 30-day complications and 30-day reintervention (all p < 0.001). Conclusion We have shown that an operative difficulty scale can standardise the description of operative findings by multiple grades of surgeons to facilitate audit, training assessment and research. It provides a tool for reporting operative findings, disease severity and technical difficulty and can be utilised in future research to reliably compare outcomes according to case mix and intra-operative difficulty
