MOTOR VEHICLES AND TRAFFIC Driver\u27s Licenses: Repeal Certain Requirements for Habitual Offender Applicants for Probationary Licenses; Provide Administrative Suspension for First Time Offenders; Limit Driving Permits; Change Allowable Blood Alcohol Content for Drivers Under the Age of Eighteen; Provide for Administrative Suspensions and Service of Notice of Suspensions; Provide for Driving Under the Influence; Prohibit Certain Nolo Contendere Pleas; Require that Testing Machines Work Properly

Act 1008 eliminates the requirement for the Department of Public Safety to do a criminal records check on habitual violators applying for a probationary license. Act 1209 tightens up Georgia Driving Under the Influence (DUD laws by changing the provisions relating to limited driving permits. These provisions include the issuance of temporary driving permits; the administration of chemical tests; the suspension of licenses for refusing to submit to a blood alcohol level test; the service of notice of such a suspension; the terms and conditions of an administrative suspension of license; the basic provisions for driving under the influence; the elimination of nolo contendere pleas for serious first time offenders; and the requirement that all the parts in blood alcohol level testing machines be in proper working order

Intensive Cultural Resources Survey Of The Proposed Hunt University 35-19 Pipeline Within Reagan County, Texas

On behalf of Medallion Midstream, LLC. (Medallion) SWCA Environmental Consultants (SWCA) conducted an intensive cultural resources survey of the proposed Hunt University 35-19 Pipeline which crosses property owned by University of Texas Lands (University Lands) in Reagan County, Texas. The proposed project will be constructed within Medallion’s easement, totaling approximately 2.40 miles (3.86 kilometers [km]) in Reagan County; however, only 2.36 miles (3.80 km) of the project will be on University Lands. Because portions of the proposed undertaking will occur on land owned by University Lands, a political subdivision of the state, the work was performed in compliance with the Antiquities Code of Texas (ACT) under Texas Antiquities Permit No. 8467. All investigations were conducted in accordance with Texas Historical Commission (THC) and Council of Texas Archeologists standards. The investigations consisted of a background literature and records review and an intensive cultural resources survey. The work was performed to identify cultural resources within the project area and provide recommendations regarding their significance and management. As part of the background literature and records review, SWCA investigated a 1-mile (1.6-km) radius of the currently proposed project area. The background literature review determined that two previous cultural resources surveys are known to have been conducted within portions of the proposed project area; however, no archaeological sites have been recorded within the project area. Three additional cultural resources surveys, and no known archaeological sites are located within a 1-mile (1.6-km) radius of the project area. The historic map review did not identify any potentially historic-age structures within or immediately adjacent to (within 350 feet [107 meters] of) the current project area; however, a potential historic ranch complex was identified approximately 0.85 mile (1.37 km) east of the southern terminus of the proposed project area. SWCA archaeologists surveyed the entire 2.40-mile-long (3.86-km-long) project area using intensive shovel test excavations and examination of available exposures. The survey encountered vegetation typical of the Semiarid Edwards Plateau ecoregion, generally consisting of arid-land scrub brush and short grasses, underlain by calcareous soil with a shallow limestone bedrock. SWCA conducted pedestrian survey, augmented with shovel testing, along the entire length of the 2.40- mile (3.86-km) project area, within a 100-foot (30.5-meter) wide corridor. The THC’s survey standards require a minimum of 16 shovel tests per mile, per 100 feet of corridor width with thorough documentation of all exceptions (e.g., disturbance, slope, and impervious surfaces). Based on these standards, the project area required 39 shovel tests. SWCA excavated a total of 44 shovel tests within the project area, exceeding the THC’s required survey standards. No cultural materials were identified on the ground surface or within any of the shovel tests excavated within the project area. In accordance with the ACT, SWCA made a reasonable and good faith effort to identify cultural resources within the project area. No archaeological sites were identified that meet the criteria for designation as a State Antiquities Landmark, per 13 Texas Administrative Code 26.12; therefore, SWCA recommends that no additional cultural resources investigations should be warranted within the project area, as currently defined

Methodology for Microscopic Traffic Simulation Modelling of Land Port of Entries along the U.S.-Mexican Border: Ysleta – Zaragoza Land Port of Entry Case Study

AbstractLand Ports of Entry (LPOEs) are facilities that control access into the U.S., as well as departures of persons and freight. While traffic simulation modeling techniques are not typically used to evaluate LPOE operational processes, they should be considered more often, because LPOEs have a significant impact on surrounding traffic conditions and vice versa. This paper proposes a methodology for developing microscopic traffic simulation models of LPOEs along the U.S.-Mexico border. The methodology consists of seven steps: (i) collect data; (ii) develop traffic or roadway network; (iii) model inspection and toll booths; (iv) develop traffic management strategies; (v) set up traffic demand; (vi) calibrate model; and (vii) validate model. The paper also presents a case study in which this methodology was followed to develop the Ysleta – Zaragoza LPOE traffic simulation model, which can be controlled from a web-based interface to help LPOE personnel without previous transportation modeling experience

Variability in H9N2 haemagglutinin receptor-binding preference and the pH of fusion

H9N2 avian influenza viruses are primarily a disease of poultry; however, they occasionally infect humans and are considered a potential pandemic threat. Little work has been performed to assess the intrinsic biochemical properties related to zoonotic potential of H9N2 viruses. The objective of this study, therefore, was to investigate H9N2 haemagglutinins (HAs) using two well-known correlates for human adaption: receptor-binding avidity and pH of fusion. Receptor binding was characterized using bio-layer interferometry to measure virus binding to human and avian-like receptor analogues and the pH of fusion was assayed by syncytium formation in virus-infected cells at different pHs. We characterized contemporary H9N2 viruses of the zoonotic G1 lineage, as well as representative viruses of the zoonotic BJ94 lineage. We found that most contemporary H9N2 viruses show a preference for sulphated avian-like receptor analogues. However, the ‘Eastern’ G1 H9N2 viruses displayed a consistent preference in binding to a human-like receptor analogue. We demonstrate that the presence of leucine at position 226 of the HA receptor-binding site correlated poorly with the ability to bind a human-like sialic acid receptor. H9N2 HAs also display variability in their pH of fusion, ranging between pH 5.4 and 5.85 which is similar to that of the first wave of human H1N1pdm09 viruses but lower than the pH of fusion seen in zoonotic H5N1 and H7N9 viruses. Our results suggest possible molecular mechanisms that may underlie the relatively high prevalence of human zoonotic infection by particular H9N2 virus lineages

Online Media Forums as Separate Social Lives: A Qualitative Study of Disclosure Within and Beyond Reddit

Social media websites and web forums increasingly resemble massive media-sharing spaces where participants must manage self-presentation by targeting data disclosures to anticipated audiences. To explore the dynamics of selective disclosure, we conducted a qualitative study with participants on the social news site, reddit, and examined how people discuss its content in conversation on the website, in other websites, and in face-to-face conversation. We conducted 24 interviews with users and analyzed a supplementary corpus of popular reddit threads and reddit Internet Relay Chat logs. We also made regular use of the website to ground our understanding of the community. In our inductive analysis we found that many reddit users described deliberate social choices to compartmentalize discussions involving content on the website from their social lives beyond.ye
