The Kontsevich constants for the volume of the moduli of curves and topological recursion

We give an Eynard-Orantin type topological recursion formula for the canonical Euclidean volume of the combinatorial moduli space of pointed smooth algebraic curves. The recursion comes from the edge removal operation on the space of ribbon graphs. As an application we obtain a new proof of the Kontsevich constants for the ratio of the Euclidean and the symplectic volumes of the moduli space of curves.Comment: 37 pages with 20 figure

Anxiety and control in African American families.

To investigate the effects of anxiety and ethnicity on parental control as well as the effects ethnicity, anxiety, and parental control have on child diagnostic severity, anxious African American and Caucasian families were compared. Sixty-nine parent-child dyads completed the study. Forty-two mothers in the sample suffered from an anxiety disorder whereas twenty-seven mothers did not meet criteria for any current or past psychopathology. Parent-child dyads were videotaped as they completed two mildly stressful tasks together. Parental and child behaviors during the interactions were coded to obtain an objective measure of parents\u27 behavior. Data were reduced to produce four behavioral composites one of which, overcontrolling, was used to assess objective ratings of parental control. Subjective parental control was assessed by two self-report measures of parenting behaviors. Four hierarchical linear regressions were conducted. It was hypothesized that parental anxiety would predict high control in Caucasian families whereas parental anxiety would predict low parental control in African American families. It was further hypothesized that parental control would positively predict child diagnostic severity in anxious Caucasian families whereas parental control would negatively predict child diagnostic severity in anxious African American families. Ethnicity did not significantly predict parental control in either group. As expected, parental anxiety predicted child diagnostic severity. Ethnicity did not significantly predict child diagnostic severity as an outcome variable. The interaction term of ethnicity and parental anxiety failed to predict both objective ratings of parental control and subjective ratings of parental control. The interaction term of ethnicity, parental control (both objective and subjective ratings), and parental anxiety failed to predict child diagnostic severity. Exploratory analyses indicated that both subjective parental control and ethnicity play integral roles along with parental anxiety in predicting child diagnostic status. Exploratory analyses further indicated that anxious Caucasian parents and highly controlling Caucasian parents are more likely than African American parents in general to have an anxious child. Findings from the current sample indicate that anxious African American and Caucasian parents do not seemingly differ with regard to control behaviors toward their children, although African Americans seem less likely to have an anxious child. Future directions are discussed in terms of matched samples of African American and Caucasian families, within group comparisons of African American families, further objective measurement, improved subjective ratings of parental control, and larger sample size

Comparison of Archeological Survey Techniques at Camp Lawton, a Civil War Prison Stockade

In 2009, Dr. Sue Moore of Georgia Southern University was contacted by State Archeologist Dr. Dave Crass of the Georgia Department of Natural Resources Historic Preservation Division. He proposed an exploratory survey of the site of a Civil War Confederate prisoner of war camp known as Camp Lawton located on Magnolia Springs State Park and Bo Ginn National Fish Hatchery in Millen, Georgia. Camp Lawton was constructed, occupied, and abandoned over an approximately three month period in the fall of 1864. The survey served a twofold purpose. First, was to evaluate survey methods to determine the most efficient for use on this and similar sites. Second, was to determine the archeological integrity of the site

Cultural Resources Survey for the Granbury East Wastewater Treatment Plant, City of Granbury, Hood County, Texas (TWDB Project No. 73813)

This report presents the substantive findings of a cultural resources survey for the Granbury East Wastewater Treatment Plant (WWTP) Project, which is a component to the Wastewater Phase I Improvements Project reviewed by the Texas Water Development Board [TWDB] under Project No. 73813. The proposed Granbury East WWTP is located within a 10.6-acre (ac) property located at 3121 Old Granbury Road in the City of Granbury, Hood County, Texas. As the City of Granbury is a political entity of the State of Texas, the City is required to comply with the Antiquities Code of Texas (ACT). In addition, as the project will require federal funding from the Environmental Protection Agency through the TWDB Clean Water State Revolving Fund (CWSRF) the project must comply with the National Environmental Policy Act (NEPA), which requires compliance with the National Historic Preservation Act (NHPA). The goal of the survey was to locate, identify, and document any cultural resources, which include architectural features and archeological sites, and to evaluate such resources for their potential eligibility for inclusion in the National Register of Historic Places (NRHP). The cultural resources survey was conducted by Project Archeologist Thomas Chapman on 30 April 2020 within an approximate 10.6-ac project area or Area of Potential Effects (APE). All work conformed to 13 Texas Administrative Code 26 (13 TAC 26), which outlines the regulations for implementing the ACT, and was conducted under Antiquities Permit No. 9401. During the survey, the site boundaries for one previously recorded archeological site (41HD96), were expanded to include a portion of the current APE. Based on the lack of association with historically important individuals or events, absence of significant architectural features, and the limited archeological data potential of the site, it is the recommendation of IES that 41HD96 be considered not eligible for listing in the NRHP or designation as a SAL. Based on the findings of this cultural resources survey, IES is requesting concurrence for the APE and a “no historic properties affected” determination per 36 Code of Federal Regulations 800.4(d)(1). It is the recommendation of IES that the Texas Historical Commission (THC) concur with these findings and the Granbury East WWTP (TWDB Project No. 73813) be permitted to continue without the need for further cultural resources investigations. However, if any cultural resources (other than those documented within this report) are encountered during construction, the operators should immediately cease work in the area of the inadvertent discovery. The project cultural resources consultant should then be contacted to initiate further consultation with the THC prior to resuming construction activities. All project records generated by this project will be permanently stored at the IES office in McKinney, Texas

Cultural Resources Survey Of The Sparks Drive Connector Project, City Of Cleburne, Johnson County, Texas

This report documents the substantive findings and management recommendations of a cultural resource inventory conducted by Integrated Environmental Solutions, LLC (IES) for the Sparks Drive Connector Project, City of Cleburne, Johnson County, Texas. Per the provisions of the Antiquities Code of Texas, as the project will transpire on land owned or controlled by the City of Cleburne, which is a political subdivision of the State of Texas, the proposed project will require coordination with the Texas Historical Commission (THC) prior to construction. In addition, as the project will require a Section 404 of the Clean Water Act (CWA) permit from the U.S. Army Corps of Engineers (USACE), portions of the project within USACE jurisdiction will also be subject to the provisions of the National Historic Preservation Act (NHPA) of 1966, as amended. All work conformed to 36 Code of Federal Regulations (CFR) Part 800, and 13 Texas Administrative Code (TAC) 26, which outline the regulations for implementing Section 106 of the NHPA and the ACT, respectively. The goal of the survey was to locate, identify, and assess any cultural resources that could be adversely affected by the proposed development, and to evaluate such resources for their potential eligibility for listing as a State Antiquities Landmark (SAL) or eligibility for listing in the National Register of Historic Places (NRHP). The cultural resources inventory was conducted by archeologist Thomas Chapman on 03 August 2017, under Texas Antiquities Permit No. 8126.
