Teaching Physics to Deaf College Students In A 3-D Virtual Lab

Virtual worlds are used in many educational and business applications. At the National Technical Institute for the Deaf at Rochester Institute of Technology (NTID/RIT), deaf college students are introduced to the virtual world of Second Life, which is a 3-D immersive, interactive environment, accessed through computer software. NTID students use this virtual environment to practice concepts first encountered in the laboratory

Contemplative Motions

Bird baths and canoes are vessels that represent a dialogue with nature. Vessels are by nature a symbol for the womb, and can evoke a sense of nurturing and protection. The simplicity and beauty of these sensual objects has lead me to use them as the primary subject matter in my thesis exhibition.&nbsp; The bird bath is an offering that expresses an unconditional pleasure of nature. The classic object can be plastic, concrete or marble and still function in any of these materials as subject of enjoyment. The canoe is primarily an object of leisure time that resembles both a seed pod and sarcophagus. This visual similiarity emphasizes it's symbolic reference to passage and growth, and expands the concept of vehicle.&nbsp; These objects have come to represent a sense of optimism that prevailing attitudes have shifted towards a greater respect for the environment. Everyone has their own sense of what a vehicle is .. any of the places and sounds, any of the moments where our pressing concerns become mundane and a sense of peace and magic is found. These are moments where an object of possession can evolve into a subject of contemplation. &nbsp;</p

Health promotion in an Australian Aboriginal community: the Growing Strong Brains ® toolkit

AIM: The aim of this paper is to describe the implementation and evaluation of the Growing Strong Brains® (GSB) toolkit in a remote Aboriginal community in Western Australia (WA) over a 2-year period, 2018-2019. BACKGROUND: Ngala, a community service organisation in WA, developed the GSB toolkit in 2014, a culturally appropriate and interactive resource to build knowledge of early childhood development within Aboriginal communities. This was in response to evidence that a higher percentage of children in Aboriginal communities were developmentally vulnerable compared to the rest of the population. The GSB toolkit promotes awareness and understanding of early brain development pre-birth and in the early years of a child\u27s life. METHODS: The project was underpinned by participatory action research (PAR). Reflective PAR review cycles (n = 5) monitored local community engagement, navigated challenges and utilised community strengths. Fifty-nine local service providers attended a 2-day formal training. Data were collected by using various methods throughout the project, including feedback following training, focus groups, surveys, one-on-one interviews using yarning techniques and reflective feedback from the Project Lead. FINDINGS: Establishing local Aboriginal project staff was pivotal to the success of the project. When delivering services for and with Aboriginal people, it is essential that cultural competence, safety and decision-making is carried through from planning to implementation and evaluation, and involves genuine, respectful and authentic relationships. Sufficient time allocation directed towards building relationships with other service providers and local community members needs to be considered and built into future projects.The Growing Strong Brains® project is embedded within the local community, and anticipated implementation outcomes were achieved. The support of the local people and service providers was beyond expectation, enabling the building of local capacity, and the development of a common understanding of the key messages from the GSB toolkit to allow integration throughout all levels of the community. This project has been important to build on the strategies necessary to introduce, implement and evaluate the GSB toolkit in other remote Aboriginal communities

What Matters Most? An Exploration of Quality of Life Through the Everyday Experiences of Autistic Young People and Adults

BACKGROUND: The quality of life (QoL) of Autistic people is consistently reported to be poor compared with the general population. Little is known, however, about how Autistic people experience QoL from their perspectives and the ways they would like it to be enhanced. This qualitative study, conducted in collaboration with Autistic people, sought to understand how Autistic young people and adults define a good life and what helps and hinders them from achieving a good QoL. METHODS: We conducted semi-structured in-depth interviews with 34 Autistic adults and 14 Autistic adolescents about their everyday life experiences of different aspects of QoL, including physical health, sensory needs, mental health, money, home, transport, leisure, social connections, acceptance, and inclusion, being in charge of one's life and perceptions of the future. We coded transcripts in NVivo and analyzed them using reflexive thematic analysis. RESULTS: We identified four themes: two themes that described what a good QoL meant for our participants along with aspects of their lives that facilitated a good QoL: “feeling good” and “being myself in the world”; and two themes that described barriers to achieving a good QoL: “exhaustion and overwhelm” and “negative experiences shape perceptions.” DISCUSSION: These findings highlight the need to consider Autistic people's QoL within the context of their everyday realities. Enhancing QoL will only be achieved through focusing on these realities and through the provision of adaptations and supports to create more inclusive environments

Effect of Immediate Administration of Antibiotics in Patients With Sepsis in Tertiary Care:A Systematic Review and Meta-analysis

Purpose The goal of this review was to synthesize existing evidence regarding outcomes (mortality) for patients who present to the emergency department, are administered antibiotics immediately (within 1 hour) or later (>1 hour), and are diagnosed with sepsis. Methods A search of PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL, using the MeSH descriptors “sepsis,” “systemic inflammatory response syndrome,” “mortality,” “emergency,” and “antibiotics,” was performed to identify studies reporting time to antibiotic administration and mortality outcome in patients with sepsis. The included studies (published in English between 1990 and 2016) listed patient mortality based on time to antibiotic administration. Studies were evaluated for methodologic quality, and data were extracted by using a data extraction form tailored to this study. From an initial pool of 582 potentially relevant studies, 11 studies met our inclusion criteria, 10 of which had quantitative data for meta-analysis. Three different models (a random effects model, a bias-adjusted quality-effects [synthetic bias] model, and an inverse variance heterogeneity model) were used to perform the meta-analysis. Findings The pooled results suggest a significant 33% reduction in mortality odds for immediate (within 1 hour) compared with later (>1 hour) antibiotic administration (OR, 0.67 [95% CI, 0.59–0.75]) in patients with sepsis. Implications Immediate antibiotic administration (<1 hour) seemed to reduce patient mortality. There was some minor negative asymmetry suggesting that the evidence may be biased toward the direction of effect. Nevertheless, this study provides strong evidence for early, comprehensive, sepsis management in the emergency department

Loneliness, HPA Stress Reactivity and Social Threat Sensitivity: Analyzing Naturalistic Social Challenges

Loneliness has been linked to poor health through an increased activation of threat surveillance mechanisms, such as the hypothalamic-pituitary-adrenal axis (HPA). The socio-cognitive model (Cacioppo & Hawley, 2009) proposes that lonely people have an increased social threat sensitivity which activates the HPA axis. The current study examined the impact of loneliness on HPA stress reactivity and social threat sensitivity in response to naturally occurring social challenges. Participants (N = 45) were prospective undergraduates attending a 3-day university preparation programme over the summer, prior to commencing their university studies. Cortisol levels and perceived stress were measured before and after an ice breaker session on Day 1 and a lecture session on Day 3. Social threat sensitivity was also measured on the first and third day. When meeting unfamiliar peers in the ice breaker session, HPA stress reactivity was evident, but it was not markedly different in those who reported high levels of loneliness than those with low levels. The high loneliness group had higher levels of perceived stress and increased social threat sensitivity than the low loneliness group on both testing days. The findings show partial support for the socio-cognitive model of loneliness because increased threat sensitivity was demonstrated in the high loneliness group. The findings indicate that lonely people do not respond in a physiologically different way to specific social challenges, but they typically report higher social threat sensitivity and higher perceived stress than their non-lonely peers

Variable Galaxies in the Hubble Deep Field

We present results from a study to detect variable galaxies in the Hubble Deep Field North. The goal of this project is to investigate the number density of AGN at z=1 through the detection of variable galaxy nuclei. The advantage of HST is the ability to do accurate photometry within smaller apertures, thus allowing us to probe much lower AGN/host galaxy luminosity ratios than can be done from the ground. The primary data sets analyzed for galactic variability follow from the original HDF-N observations in December 1995 and a second epoch obtained two years later. We have detected nuclear variability at or above the 3 sigma level in 8 of 633 HDF galaxies at I<27. Only 2 detections would be expected by chance in a normal distribution. At least one of these 8 has been spectroscopically confirmed as a Seyfert 1 galaxy. Based on the AGN structure function for variability, the estimated luminosity of the varying component in each galaxy lies in the range -19.5<M<-15.0. We construct an upper limit to the luminosity function for the variable nuclei and compare this to the local Seyfert LF and the LF for QSOs at z=1. Assuming we have detected all Seyfert-like nuclei in the HDF-N, we find no evidence for an increase in the number density of AGN at M=-19. We estimate that ~1-3% of field galaxies with I<27 may contain a nuclear AGN.Comment: 31 pages, 8 figures, accepted to the A
