Visual art communities of practice: cultivating support for beginning visual art teachers
Visual art teachers, from beginning to veteran, often report experiencing feelings of professional isolation and a desire for content-specific support and collaborative professional learning experiences. Mentoring and Induction Programs (IPs) offered by schools and districts continue to fall short of meeting the needs of beginning visual art teachers in particular. There are a large number of visual art teachers in the state of California, especially in Los Angeles County, yet there are no visual art specific support networks for beginning visual art teachers to help them navigate their first years teaching. Collaborative learning groups, such as communities of practice (CoP), may offer visual art teachers opportunities to learn together and support one another in shared learning, yet none have been formally documented in Los Angeles County as a means of supporting novice art educators. The Exploratorium in San Francisco, CA has established a community practice called the Teacher Induction Program (TIP) to support beginning science teachers with content-specific pedagogy during their first two years of teaching. Using the TIP as a framework, a visual art professional growth support community was outlined for this study based on the needs and concerns of visual art teachers reported throughout the literature. Beginning visual art teachers in Los Angeles county were interviewed to help the researcher better understand their existing and desired supports, as well as their individual needs and concerns as new teachers. The visual art CoP was proposed to them to elicit feedback about its anticipated values (immediate, potential, applied) based on their lived experiences as first or second year PK-12 public school visual art teachers in Los Angeles County
True Confessions From a Wannabee Heel
True Confessions from a Wannabe Heel is a collection composed of memoir -themed personal essays in lyrical and mosaic styles touching on the themes of violence, wrestling, sexuality, love, mental health, and the significance of home. The essays are representative of my experiences growing up in an unstable home and how the effects of growing up in that environment shaped how I view the world around me. There are essays reflecting on how we perceive violence in the world, and how that violence has become more widely accepted, and how the line that we draw for what is acceptable seems to move with each trauma. The collection also explores the dynamics of marriage, the burdens we carry for those that we love, and the power of storytelling through a controlled lens, a theme highlighted by the strong focus on different wrestling storylines
Predictors of Treatments Acceptable to Patients for Late-Life Depression
Objectives. Describe older patients’ perceptions about depression and characteristics associated with acceptance of treatments. Design. Cross-sectional study. Setting. Three primary care clinics in Iowa. Participants. Consecutive sample of 529 primary care patients. Measurements. Depression screening tool (a 9-item patient health questionnaire [PHQ-9]) and questionnaire including sociodemographic data, patient attitudes about depression, and acceptability of different treatments. Results. Mean age was 71.9 years (range 60–93 years), 314 (59%) female. Among the 529 participants, 93 (17.5%) had history of depression and 60 (11.3%) had PHQ-9 scores of 10 or greater. Participants believed depression is a disease for which they would use medication and counseling. Accepting medications from primary physicians was strongly associated with a past history of depression (P \u3c 0.01) and with agreeing that depression needs treatment (P \u3c 0.01). Counseling was not acceptable for those believing that they can control depression on their own (P \u3c 0.01). Older patients (P \u3c 0.001) and those with higher education levels (P \u3c 0.01) were less likely to accept herbs or supplements as treatment options. Willingness to discuss treatments with family was associated with not using alcohol as a treatment and acceptance of all other treatment options (P \u3c 0.001). Conclusions. Attitude that depression is a disease and the willingness to discuss depression with family may enhance treatment acceptance
Bringing home the trash: Do colony-based differences in foraging distribution lead to increased plastic ingestion in Laysan albatrosses?
When searching for prey, animals should maximize energetic gain, while minimizing energy expenditure by altering their movements relative to prey availability. However, with increasing amounts of marine debris, what once may have been ‘optimal’ foraging strategies for top marine predators, are leading to sub-optimal diets comprised in large part of plastic. Indeed, the highly vagile Laysan albatross (Phoebastria immutabilis) which forages throughout the North Pacific, are well known for their tendency to ingest plastic. Here we examine whether Laysan albatrosses nesting on Kure Atoll and Oahu Island, 2,150 km apart, experience different levels of plastic ingestion. Twenty two geolocators were deployed on breeding adults for up to two years. Regurgitated boluses of undigestable material were also collected from chicks at each site to compare the amount of plastic vs. natural foods. Chicks from Kure Atoll were fed almost ten times the amount of plastic compared to chicks from Oahu despite boluses from both colonies having similar amounts of natural food. Tracking data indicated that adults from either colony did not have core overlapping distributions during the early half of the breeding period and that adults from Kure had a greater overlap with the putative range of the Western Garbage Patch corroborating our observation of higher plastic loads at this colony. At-sea distributions also varied throughout the year suggesting that Laysan albatrosses either adjusted their foraging behavior according to constraints on time away from the nest or to variation in resources. However, in the non-breeding season, distributional overlap was greater indicating that the energy required to reach the foraging grounds was less important than the total energy available. These results demonstrate how a marine predator that is not dispersal limited alters its foraging strategy throughout the reproductive cycle to maximize energetic gain and how this has led to differences in plastic ingestion
Simulation of individual leaf areas in grain sorghum
Most crop simulation models that incorporate environmental conditions estimate leaf area development. The grain sorghum growth simulation model, SORKAM, calculates individual leaf area based on leaf number and maturity class. The objective of this study was to generalize present leaf growth routines in SORKAM to be independent of maturity since there are no generally accepted maturing classes. Modified relationships between leaf number and leaf growth parameters were developed from existing studies and were tested against independent detailed leaf growth data sets. The revised relationships improved the r2 between simulated and actual individual leaf areas from 0.80 to 0.88, reduced the bias from 32 cm2 to 9 cm2, and the RMSE from 80 cm2 to 52 cm2. With the improved simulation, estimated leaf area index through the season was also improved from the original SORKAM estimate (RMSE decreased from 0.77 to 0.63; RMSE: root mean square error). Although simulation of individual leaf areas was improved, total leaf area produced over the season was not

3D Gamma-ray and Neutron Mapping in Real-Time with the Localization and Mapping Platform from Unmanned Aerial Systems and Man-Portable Configurations
Nuclear Scene Data Fusion (SDF), implemented in the Localization and Mapping
Platform (LAMP) fuses three-dimensional (3D), real-time volumetric
reconstructions of radiation sources with contextual information (e.g. LIDAR,
camera, etc.) derived from the environment around the detector system. This
information, particularly when obtained in real time, may be transformative for
applications, including directed search for lost or stolen sources, consequence
management after the release of radioactive materials, or contamination
avoidance in security-related or emergency response scenarios. 3D
reconstructions enabled by SDF localize contamination or hotspots to specific
areas or objects, providing higher resolution over larger areas than
conventional 2D approaches, and enabling more efficient planning and response,
particularly in complex 3D environments.
In this work, we present the expansion of these gamma-ray mapping concepts to
neutron source localization. Here we integrate LAMP with a custom
(CLLBC) scintillator detector sensitive to both
gamma-rays and neutrons, which we dub Neutron Gamma LAMP (NG-LAMP). NG-LAMP
enables simultaneous neutron and gamma-ray mapping with high resolution
gamma-ray spectroscopy. We demonstrate the ability to detect and localize
surrogate Special Nuclear Materials (SNM) in real-time and in 3D based on
neutron signatures alone, which is critical for the detection of heavily
shielded SNM, when gamma-ray signatures are attenuated. In this work, we show
for the first time the ability to localize, in 3D and realtime, a neutron
source in the presence of a strong gamma-ray source, simultaneous and
spectroscopic localization of three gamma-ray sources and a neutron source, and
finally the localization of a surrogate SNM source based on neutron signatures
alone, where gamma-ray data are consistent with background
