Multi-agent scavenging patterns in Hawai‘i: A forensic archaeological and skeletal case study

Knowledge of the behavior of local fauna can aid forensic investigators in developing awareness of site formation processes. In Hawai‘i, little has been published on the effects of feral domestic pig (Sus scrofa) and feral domestic dog (Canis familiaris) scavenging and bone dispersal on field recovery and laboratory observations. In this Pacific tropical setting, the most consequential terrestrial taphonomic agents are pigs and dogs, both in terms of hard tissue modification and dispersal of remains across the landscape. In 2017, an archaeologist discovered the remains of an unidentified decedent on the island of Kauaʻi, State of Hawai‘i during a cultural resource management survey. Subsequently, a forensic recovery team in conjunction with Kaua‘i police and crime scene investigators used archaeological techniques, including pedestrian survey, tape-and-compass, and GPS mapping, to map and recover the remains. A feral pig trail transected various areas of the recovery site and corresponded with the distribution pattern of recovered skeletal material, including both the main concentration more broadly dispersed skeletal elements. While much of the skeleton was present, missing or unrecovered skeletal elements are consistent with expectations based on existing literature. Much of the postmortem bone deformations were characteristic of marks related to feral dog and/or feral pig scavenging. These results assisted local investigators in deciding the manner of death, as well as providing the family with an accounting of the decedent’s remains for burial. Thus, forensic anthropologists and archaeologists need to understand and develop knowledge of local animal behavior to recover and interpret human remains of medicolegal significance

Disability and Impairment of the Hand: Trauma Analysis of the Erie County Poorhouse Cemetery

Hands are one of the most frequently used parts of the body and, as such, are historically and intrinsically linked to daily functioning and the ability to work. Thus, the bioarchaeological analysis of hand bones can prove to be a useful resource in evaluating the lived experiences of past peoples. The current study analyzes antemortem hand trauma observed in individuals exhumed from the Erie County Poorhouse Cemetery (1851-1913), located in Buffalo, New York. In doing so we investigate patterns of trauma distribution and subsequent severity of impairment of the hand. These impairments are then used as a window into the occupational realities of the institutionalized poor in an Industrial Revolution era urban setting. Of the 271 individuals with observable hand bones, 42 (15.5%) displayed trauma in the form of a bone fracture, avulsion fracture, or joint dislocation. There were 55 females and 109 males, of which 5 (9%) and 24 (22%), respectively, displayed trauma. This was a statistically significant difference in trauma occurrences (X2 (1) = 4.197, p = .040). These findings likely reflect occupational differences between men and women. When comparing hand trauma by side (e.g., left and right hand), a significant difference was found with more trauma on the right (t = -1.972; p = 0.049). Impairment scoring of the injuries revealed that individuals suffered mild impairment and subsequent disability of their hand(s). These impairments may be indicative of the hazardous, often unregulated workplace conditions of the time as well as potential instances of interpersonal violence.https://digitalscholarship.unlv.edu/durep_posters/1064/thumbnail.jp

South Eastern Interprofessional Collaborative Learning Environment (SEIPCLE): Nurturing Collaborative Practice

AbstractBackground: There has been tremendous pressure on Canada’s healthcare system to respond to the increasingly complex health needs of the population despite worsening constraints in financial and human resources. Interprofessional collaborative practice has been seen as an enabler for improving patient care and meeting the current demands on the healthcare system.Methods: The South Eastern Interprofessional Collaborative Learning Environment (SEIPCLE) project, funded by HealthForceOntario, focused on the development and evaluation of the collaborative practice care model in three clinical settings in Southeastern Ontario, Canada. The project was exploratory in nature and used a quasi-experimental design with pre- and post-tests matched with non-equivalent control groups. Several different measures were used, including the Collaborative Practice Assessment Tool (CPAT), an Interprofessional Clinical Education Survey, and a Patient Participation Survey. Quantitative outcome measures were derived from these instruments using factor analysis, and analyzed using regression modelling with co-variates. Focus groups, interviews, and questionnaires provided qualitative data that was coded conceptually and used to complement the results of analyses using quantitative measures. Intervention teams participated in educational components that addressed identified weaknesses in their collaborative practice. Educational components included online modules, workshops, and real-time activities.Findings: Implementation of educational components in the clinical setting posed a number of challenges to reducing the exposure time for some of the intervention teams. Barriers to and enablers of the development of collaborative practice in the healthcare system were identified.Conclusion: Overall, all three intervention teams demonstrated an increase in perceived levels of collaborative practice. Although the results were not statistically significant, the effect, size, and magnitude of change were considered substantial

Yes, The Government Should Tax Soft Drinks: Findings from a Citizens’ Jury in Australia

Taxation has been suggested as a possible preventive strategy to address the serious public health concern of childhood obesity. Understanding the public’s viewpoint on the potential role of taxation is vital to inform policy decisions if they are to be acceptable to the wider community. A Citizens’ Jury is a deliberative method for engaging the public in decision making and can assist in setting policy agendas. A Citizens’ Jury was conducted in Brisbane, Australia in May 2013 to answer the question: Is taxation on food and drinks an acceptable strategy to the public in order to reduce rates of childhood obesity? Citizens were randomly selected from the electoral roll and invited to participate. Thirteen members were purposively sampled from those expressing interest to broadly reflect the diversity of the Australian public. Over two days, participants were presented with evidence on the topic by experts, were able to question witnesses and deliberate on the evidence. The jurors unanimously supported taxation on sugar-sweetened drinks but generally did not support taxation on processed meats, snack foods and foods eaten/ purchased outside the home. They also supported taxation on snack foods on the condition that traffic light labelling was also introduced. Though they were not specifically asked to deliberate strategies outside of taxation, the jurors strongly recommended more nutritional information on all food packaging using the traffic light and teaspoon labelling systems for sugar, salt and fat content. The Citizens’ Jury suggests that the general public may support taxation on sugar-sweetened drinks to reduce rates of obesity in children. Regulatory reforms of taxation on sugar-sweetened drinks and improved labelling of nutritional information on product packaging were strongly supported by all members of the jury. These reforms should be considered by governments to prevent childhood obesity and the future burden on society from the consequences of obesity

Supporting International Ab Initio Flight Students Through English Language Training

Effective communication between ab initio flight students and their instructors is critical for efficient flight training; additionally, clear radio communications between student pilots and air traffic controllers is imperative for smooth and incident-free airport operations. During the Fall 2019 semester, Embry-Riddle Aeronautical University (ERAU) at Daytona Beach implemented a new semi-intensive eight-week course to improve the communicative skills of its international students who speak English as a second language. This presentation describes the cross-campus and cross-departmental collaboration that took place to implement this new course. The stages that will be described include (a) the pre-screening of the students using ERAU’s online, remotely administered English for Flight Training Assessment (EFTA)™, a project initiated by Daytona Beach’s Applied Aviation Sciences Department and the Embry-Riddle Language Institute, and (b) the employment of a curriculum specifically designed for ab-initio flight students based on flight training materials created by the Aviation English Specialists at ERAU, Worldwide. The presenters will describe the teaching approaches used during the course and provide insights about the challenges faced and lessons learned throughout the eight weeks. The topic of aviation-familiarity for English language instructors will be discussed along with plans for improving the course. The audience will leave with insights about how to directly support international ab initio flight students and understand how ERAU’s approach to effective English language training can serve as an exemplar for the industry

NFIRAOS adaptive optics for the Thirty Meter Telescope

NFIRAOS (Narrow-Field InfraRed Adaptive Optics System) will be the first-light multi-conjugate adaptive optics system for the Thirty Meter Telescope (TMT). NFIRAOS houses all of its opto-mechanical sub-systems within an optics enclosure cooled to precisely -30°C in order to improve sensitivity in the near-infrared. It supports up to three client science instruments, including the first-light InfraRed Imaging Spectrograph (IRIS). Powering NFIRAOS is a Real Time Controller that will process the signals from six laser wavefront sensors, one natural guide star pyramid WFS, up to three low-order on-instrument WFS and up to four guide windows on the client instrument’s science detector in order to correct for atmospheric turbulence, windshake, optical errors and plate-scale distortion. NFIRAOS is currently preparing for its final design review in late June 2018 at NRC Herzberg in Victoria, British Columbia in partnership with Canadian industry and TMT

The colonial ascidian Didemnum sp. A: Current distribution, basic biology and potential threat to marine communities of the northeast and west coasts of North America

The definitive version was published in Journal of Experimental Marine Biology and Ecology 342 (2007): 99-108, doi:10.1016/j.jembe.2006.10.020.Didemnum sp. A is a colonial ascidian with rapidly expanding populations on the east and west coasts of North America. The origin of Didemum sp. A is unknown. Populations were first observed on the northeast coast of the U.S. in the late 1980s and on the west coast during the 1990s. It is currently undergoing a massive population explosion and is now a dominant member of many subtidal communities on both coasts. To determine Didemnum sp. A’s current distribution, we conducted surveys from Maine to Virginia on the east coast and from British Columbia to southern California on the west coast of the U.S. between 1998 and 2005. In nearshore locations Didemnum sp. A currently ranges from Eastport, Maine to Shinnecock Bay, New York on the east coast. On the west coast it has been recorded from Humboldt Bay to Port San Luis in California, several sites in Puget Sound, Washington, including a heavily fouled mussel culture facility, and several sites in southwestern British Columbia on and adjacent to oyster and mussel farms. The species also occurs at deeper subtidal sites (up to 81 m) off New England, including Georges, Stellwagen and Tillies Banks. On Georges Bank numerous sites within a 147 km2 area are 50-90% covered by Didemnum sp. A; large colonies cement the pebble gravel into nearly solid mats that may smother infaunal organisms. These observations suggest that Didemnum sp. A has the potential to alter marine communities and affect economically important activities such as fishing and aquaculture.Funding for this project was provided by EPA (STAR) grant GZ1910464 to R.B.

NFIRAOS: TMT's facility adaptive optics system

NFIRAOS, the TMT Observatory's initial facility AO system is a multi-conjugate AO system feeding science light from 0.8 to 2.5 microns wavelength to several near-IR client instruments. NFIRAOS has two deformable mirrors optically conjugated to 0 and 11.2 km, and will correct atmospheric turbulence with 50 per cent sky coverage at the galactic pole. An important requirement is to have very low background: the plan is to cool the optics; and one DM is on a tip/tilt stage to reduce surface count. NFIRAOS' real time control uses multiple sodium laser wavefront sensors and up to three IR natural guide star tip/tilt and/or tip/tilt/focus sensors located within each client instrument. Extremely large telescopes are sensitive to errors due to the variability of the sodium layer. To reduce this sensitivity, NFIRAOS uses innovative algorithms coupled with Truth wavefront sensors to monitor a natural star at low bandwidth. It also includes an IR acquisition camera, and a high speed NGS WFS for operation without lasers. For calibration, NFIRAOS includes simulators of both natural stars at infinity and laser guide stars at varying range distance. Because astrometry is an important science programme for NFIRAOS, there is a precision pinhole mask deployable at the input focal plane. This mask is illuminated by a science wavelength and flat-field calibrator that shines light into NFIRAOS' entrance window. We report on recent effort especially including trade studies to reduce field distortion in the science path and to reduce cost and complexity

Inflation and Dark Energy from spectroscopy at z > 2

The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at z < 1, when Dark Energy is hypothesized to drive cosmic acceleration. The undiscovered mechanisms behind these two epochs represent some of the most important open problems in fundamental physics. The large cosmological volume at 2 < z < 5, together with the ability to efficiently target high-$z$ galaxies with known techniques, enables large gains in the study of Inflation and Dark Energy. A future spectroscopic survey can test the Gaussianity of the initial conditions up to a factor of ~50 better than our current bounds, crossing the crucial theoretical threshold of $\sigma(f_{NL}^{\rm local})$ of order unity that separates single field and multi-field models. Simultaneously, it can measure the fraction of Dark Energy at the percent level up to $z = 5$, thus serving as an unprecedented test of the standard model and opening up a tremendous discovery space
