Results of Significance Testing at 41DW269 Dewitt County, Texas
Site 41DW269 was tested by Texas Department of Transportation (TxDOT) archeologists in July of 1997. The investigations were conducted in the right-of-way of a proposed bridge replacement project on DeWitt County Road 122 at its crossing of Clear Creek. The investigations at Site 41DW269 consisted of mechanical trenching for archeological prospection and stratigraphic evaluation of the site, and the manual excavation of two 1 x 1 m test units and two shovel tests.
Site 41DW269 is a multi-component terrace site with cultural deposits ranging in age from the Early Archaic through the Late Archaic. Two discrete alluvial fills, both containing cultural material, underlie the terrace. Unit 1 forms the core of the terrace and consists of a dark brown, sandy to silty loam to clay loam containing abundant secondary calcium carbonate. Unit 2 consists of a very dark grayish brown to black loam that represents a veneer of more recent overbank deposits that is approximately 1.0 to 1.2 m thick. In addition, two younger alluvial fills (Units 3 and 4) are present across the stream and at the base of the cutbank forming the northern site boundary. Testing of the site revealed two clearly distinct prehistoric cultural strata within deep alluvial deposits, and a single pit-like feature. The first cultural deposit is associated with Unit 1, and consists of a sparse assemblage of mineralized bone and lithic material extending from approximately 120-180 cm below the present ground surface. On the basis of a single radiocarbon age and a diagnostic Guadalupe tool, this component is believed to date to the Early Archaic. The second cultural deposit is associated with the upper veneer, and extends from approximately 10 cm to 110 cm below the surface. Although this deposit could not be subdivided based on the limited excavation data, it contains a cultural debris associated with Late Archaic and possibly Middle Archaic occupations
Due to the deep and stratified nature of the deposits and the diversity of artifactual assemblages at the site, 41DW269 is considered eligible for inclusion in the National Register of Historic Places and for designation as a State Historic Landmark

Positive impacts on rural and regional workforce from the first seven cohorts of James Cook University medical graduates
Introduction: The regionally-based James Cook University (JCU) School of Medicine aims to meet its mission to address the health needs of the region by combining selection and curriculum strategies shown to increase rural career recruitment outcomes. The School has graduated 536 students in its first seven cohorts from 2005 to 2011. This paper presents the early career practice locations and the specialty training undertaken by these cohorts, and describes the association between later practice location with both hometown at application and internship location.
Methods: 'Hometown at application' data for JCU Bachelor of Medicine, Bachelor of Surgery (MBBS) graduates was retrieved from administrative databases held by the university, while postgraduate location and career data were obtained either from personal contact via email, telephone, Facebook or electronically from the Australian Health Practitioner Regulation Authority website. Practice location was described across Australian Standard Geographical Classification Remoteness Area (RA) categories.
Results: Data for the primary practice location of 536 JCU MBBS graduates across postgraduate years (PGY) 1 to 7 is 99% complete. A total of 65% of JCU graduates undertook their internship in non-metropolitan locations including 20% in RA 2 and 44% in RA 3–5, a pattern of practice different to that of other Australian clinicians. For the internship year, 'non-metropolitan-origin' JCU MBBS graduates predominantly worked in RA 2–5 locations, while 'metropolitan origin' graduates were more likely to work in major cities. However, by PGY 7, the distribution of 'rural' and 'metropolitan' origin JCU graduates across RA categories was similar. The RA category of internship location – either 'metropolitan' (RA 1) or 'non-metropolitan' (RA 2–5) – was associated with the location of subsequent practice across PGY 2–7.
Conclusions: This comprehensive data set provides the first real evidence from one of Australia's new medical schools on actual postgraduate practice location, as compared to 'intent to practice'. The geographic profile by RA of JCU graduates' hometown and patterns of postgraduate practice is different to that of other Australian medical students and doctors. This early evidence supports the JCU model of distributed non-metropolitan medical education, and suggests more regionally-located internship and specialty training places would further increase the medical workforce in northern and/or rural Australia. The workforce impact of the seven cohorts of graduates in this study is starting to be felt in rural and regional Australia, and, if these trends continue, will result in significant workforce improvements over the next decade. These results support further investment in regional and rural medical education
Vitrification and determination of the crystallization time scales of the bulk-metallic-glass-forming liquid Zr58.5Nb2.8Cu15.6Ni12.8Al10.3
The crystallization kinetics of Zr58.5Nb2.8Cu15.6Ni12.8Al10.3 were studied in an electrostatic levitation (ESL) apparatus. The measured critical cooling rate is 1.75 K/s. Zr58.5Nb2.8Cu15.6Ni12.8Al10.3 is the first bulk-metallic-glass-forming liquid that does not contain beryllium to be vitrified by purely radiative cooling in the ESL. Furthermore, the sluggish crystallization kinetics enable the determination of the time-temperature-transformation (TTT) diagram between the liquidus and the glass transition temperatures. The shortest time to reach crystallization in an isothermal experiment; i.e., the nose of the TTT diagram is 32 s. The nose of the TTT diagram is at 900 K and positioned about 200 K below the liquidus temperature
A successful longitudinal graduate tracking system for monitoring Australian medical school graduate outcomes
Context: Maintaining an adequate health workforce in rural and remote Australia is challenging. The Australian Government has addressed this challenge by encouraging the admission of rural background students and supporting the growth of regionally based academic health faculties and clinical schools.
Issue: It is imperative to assess the relevance and effectiveness of regionally based academic health faculties and clinical schools so standards can be maintained and health workforce supply and distribution can be maximised to benefit local populations.
Approach: The James Cook University (JCU) College of Medicine and Dentistry, the first regional Australian medical school, has developed a longitudinal tracking system for its medical graduates. Processes include administering an exit survey to each cohort immediately prior to graduation (which also collects each graduate's details and consent to be contacted for follow-up studies and practice/career choice data), a Facebook (TM) page to search for hard-to-trace graduates, and accessing the Australian Health Practitioner Regulation Authority (AHPRA) website.
Conclusions: The comprehensive personal contact tracking system backed by the AHPRA website has resulted in a 98% complete longitudinal tracking database, and thus a comprehensive picture of the practice location of JCU medical graduates from 2006 to 2013, enabling exploration of the patterns of practice to be conducted with considerable confidence. It is intended that the tracking database will be maintained for many years to allow regular follow-up of graduates well into their established careers. However, as graduate numbers increase at the JCU medical school, personal contact will be made with the majority of graduates on a less frequent basis

Program on Earth Observation Data Management Systems (EODMS)
An assessment was made of the needs of a group of potential users of satellite remotely sensed data (state, regional, and local agencies) involved in natural resources management in five states, and alternative data management systems to satisfy these needs are outlined. Tasks described include: (1) a comprehensive data needs analysis of state and local users; (2) the design of remote sensing-derivable information products that serve priority state and local data needs; (3) a cost and performance analysis of alternative processing centers for producing these products; (4) an assessment of the impacts of policy, regulation and government structure on implementing large-scale use of remote sensing technology in this community of users; and (5) the elaboration of alternative institutional arrangements for operational Earth Observation Data Management Systems (EODMS). It is concluded that an operational EODMS will be of most use to state, regional, and local agencies if it provides a full range of information services -- from raw data acquisition to interpretation and dissemination of final information products
Patient-reported outcomes measures and patient preferences for minimally invasive glaucoma surgical devices.
BackgroundMany therapeutic options are available to glaucoma patients. One recent therapeutic option is minimally invasive glaucoma surgical (MIGS) devices. It is unclear how patients view different treatments and which patient-reported outcomes would be most relevant in patients with mild to moderate glaucoma. We developed a questionnaire for patients eligible for MIGS devices and a patient preference study to examine the value patients place on certain outcomes associated with glaucoma and its therapies.ObjectivesTo summarize the progress to date.MethodsQuestionnaire development: We drafted the questionnaire items based on input from one physician and four patient focus groups, and a review of the literature. We tested item clarity with six cognitive interviews. These items were further refined. Patient preference study: We identified important benefit and risk outcomes qualitatively using semi-structured, one-on-one interviews with patients who were eligible for MIGS devices. We then prioritized these outcomes quantitatively using best-worst scaling methods.ResultsQuestionnaire testing: Three concepts were deemed relevant for the questionnaire: functional limitations, symptoms, and psychosocial factors. We will evaluate the reliability and validity of the 52-item draft questionnaire in an upcoming field test. Patient preference study: We identified 13 outcomes that participants perceived as important. Outcomes with the largest relative importance weights were "adequate IOP control" and "drive a car during the day."ConclusionsPatients have the potential to steer clinical research towards outcomes that are important to them. Incorporating patients' perspectives into the MIGS device development and evaluation process may expedite innovation and availability of these devices
