Relationship of dental practitioners to rural primary care networks
Abstract still to be addedResidents of rural and remote communities have poorer oral health and less access to oral health services than people living in major cities. The populations of many rural and remote centres are not large enough to support a resident dentist and, in the absence of community oral health services, rural residents may present to non-dental primary care providers with oral health problems.
The aim of this study was to describe strategies that can be used by primary care practitioners to improve the provision of oral health services to rural and remote communities. The specific objectives were to (i) map oral health services practices in rural communities across primary care providers (ii) assess the extent to which oral health problems impact on service provision by primary health care providers; (iii) assess the extent to which primary care networks could be more effectively utilised to improve the provision of oral health services to rural communities and to identify what interventions/strategies were most likely to be effective.The research reported in this paper is a project of the Australian Primary Health Care Research Institute which is supported by a grant from the Australian Government Department of Health and Ageing under the Primary Health Care Research Evaluation and Development Strategy
The paradox of going hungry when there is so much food : the perspective of vulnerable youth and their caseworkers
This study aimed to examine the food security challenges experienced among vulnerable youth in North West Tasmania. An exploratory, descriptive design was used to collect data through face-to-face interviews and focus group discussions with 22 young residents and with five stakeholders and representatives from different community and state organisations. The most significant finding of the study was that a proportion of young residents in the North West Coast of Tasmania were threatened by food insecurity, which was caused by a combination of factors including patterns of food consumption and dietary behaviours. Those with higher financial difficulty due to the lack of a stable job were significantly more vulnerable to food insecurity and faced a higher chance of having health problems. The findings of the project have many implications to improve the food security and lives of vulnerable youth
HIV Suppression among Patients on Treatment in Vietnam: A Review of HIV Viral Load Testing in a Public Urban Clinic in Ho Chi Minh City
Background. There are few reports of HIV viral load (VL) testing among patients on ART in Vietnam. Methods. From a public clinic in Ho Chi Minh City (HCMC), we reviewed cases of VL measurements from adults on ART. Results. We identified 228 cases. Median age was 30 years (27–34), 85% were male, and 77% had a history of IDU. The mean ART duration was 26 months (95% CI 25–27); d4T/3TC/NVP was the most common regimen. Viral suppression was seen in 160/228 (70%). Viremia (>1000 copies/mL) was associated with prior ART exposure (OR 5.68, P < .0001) and immunologic failure (OR 4.69, P = .0001). Targeted testing accounted for 13% of cases, only half of which yielded viremia. Conclusion. We demonstrate a high HIV suppression rate among patients on ART in HCMC, Vietnam. In this setting, routine testing detects viremia missed by targeted testing
Coordinated Container Migration and Base Station Handover in Mobile Edge Computing
Offloading computationally intensive tasks from mobile users (MUs) to a
virtualized environment such as containers on a nearby edge server, can
significantly reduce processing time and hence end-to-end (E2E) delay. However,
when users are mobile, such containers need to be migrated to other edge
servers located closer to the MUs to keep the E2E delay low. Meanwhile, the
mobility of MUs necessitates handover among base stations in order to keep the
wireless connections between MUs and base stations uninterrupted. In this
paper, we address the joint problem of container migration and base-station
handover by proposing a coordinated migration-handover mechanism, with the
objective of achieving low E2E delay and minimizing service interruption. The
mechanism determines the optimal destinations and time for migration and
handover in a coordinated manner, along with a delta checkpoint technique that
we propose. We implement a testbed edge computing system with our proposed
coordinated migration-handover mechanism, and evaluate the performance using
real-world applications implemented with Docker container (an
industry-standard). The results demonstrate that our mechanism achieves 30%-40%
lower service downtime and 13%-22% lower E2E delay as compared to other
mechanisms. Our work is instrumental in offering smooth user experience in
mobile edge computing.Comment: 6 pages. Accepted for presentation at the IEEE Global Communications

Vekstbedrifters sosiale nettverk
Denne bacheloroppgaven har som formål å undersøke hvilken effekt sosialt nettverk har for
veksten til norske bedrifter. Dette vil bli gjort ved å undersøke graden av sosialt nettverk hos
gasellebedrifter og sammenlikne dette opp mot en kontrollgruppe. Gasellebedrifter har en stor
betydning for sysselsetting og verdiskapning i et land, på grunn av rask vekst, ekspansjon og
omsetning (Rasmussen 2014). Arbeidsledighet er et stort problem, og Ringstad (2011) hevder
at det er at av de mest sentrale økonomiske og politiske problemene som finnes. Ved å
avdekke kriterier som kan hjelpe bedrifter til å vokse raskere, vil man kunne bidra til å øke
antall arbeidsplasser som skapes. I Norge blir dette mer relevant, etter at oljebransjen har
begynt å stagnere og det norske arbeidsmarkedet møter mer usikre tider. Resultatene av
undersøkelsen vil være til stor hjelp for å øke forståelsen, og dermed bedre tilretteleggelse for
vekst, som igjen vil føre til at det skapes mer verdi og arbeidsplasser i samfunnet.
Vi benyttet oss av kvantitative undersøkelser, i form av spørreundersøkelser, for å kunne
svare på problemstillingen: “I hvor stor grad påvirker sosialt nettverk veksten til
gasellebedrifter?”. Utvalget som skal undersøkes, består av en gruppe gasellebedrifter og en
tilsvarende kontrollgruppe bestående av små- og mellomstore bedrifter (SMB).
Oppgaven vil argumentere for at sosialt nettverk kan bli sett på som et langsiktig
konkurransefortrinn for bedrifter, ut fra et ressursbasert syn. Sosialt nettverk som fagfelt er
omfattende, og vil bli delt inn i fire underkategorier; nettverkstetthet, nettverksposisjon,
nettverksstyrke og nettverksstørrelse. Dette legger grunnlaget for våre fire hypoteser, som
viste seg å ikke være signifikante. Undersøkelsen viste ikke noe signifikant forskjell på sosialt
nettverk mellom gasellebedriftene og kontrollgruppen. Derimot viser undersøkelsen at alder
og utdannelsenivået var lavere hos gasellebedrifter (daglig leder), enn hos kontrollgruppen.
Dette kan sees i sammenheng med at gasellebedrifter ofte er yngre og mindre. Hvilken
bransje bedriften opererer i og konjunkturen til økonomien vil kunne påvirke om en bedrift
blir kategorisert som en gaselle. Hurtig vekst kan føre med seg mange nye utfordringer, som
kan hindre optimal bruk av ressurser, som for eksempel vedlikehold og utnyttelsen av sosial
kapital. Dette kan være problematisk for gasellebedrifter som opplever større vekst enn andre
A bioinformatics workflow for detecting signatures of selection in genomic data
The detection of “signatures of selection” is now possible on a genome-wide scale in many plant and animal species, and can be performed in a population-specific manner due to the wealth of per-population genome-wide genotype data that is available. With genomic regions that exhibit evidence of having been under selection shown to also be enriched for genes associated with biologically important traits, detection of evidence of selective pressure is emerging as an additional approach for identifying novel gene-trait associations. While high-density genotype data is now relatively easy to obtain, for many researchers it is not immediately obvious how to go about identifying signatures of selection in these data sets. Here we describe a basic workflow, constructed from open source tools, for detecting and examining evidence of selection in genomic data. Code to install and implement the pipeline components, and instructions to run a basic analysis using the workflow described here, can be downloaded from our public GitHub repository: http://www.github.com/smilefreak/selectionTools

The use of fluorescence correlation spectroscopy to monitor cell surface β2‐adrenoceptors at low expression levels in human embryonic stem cell‐derived cardiomyocytes and fibroblasts
The importance of cell phenotype in determining the molecular mechanisms underlying β2- adrenoceptor (β2AR) function has been noted previously when comparing responses in primary cells and recombinant model cell lines. Here, we have generated haplotype-specific SNAP-tagged β2AR human embryonic stem (ES) cell lines and applied fluorescence correlation spectroscopy (FCS) to study cell surface receptors in progenitor cells and in differentiated fibroblasts and cardiomyocytes. FCS was able to quantify SNAP-tagged b2AR number and diffusion in both ES-derived cardiomyocytes and CRISPR/Cas9 genome-edited HEK293T cells, where the expression level was too low to detect using standard confocal microscopy. These studies demonstrate the power of FCS in investigating cell surface b2ARs at the very low expression levels often seen in endogenously expressing cells. Furthermore, the use of embryonic stem cell technology in combination with FCS allowed us to demonstrate that cell surface b2ARs internalise in response to formoterol-stimulation in ES progenitor cells but not following their differentiation into ES-derived fibroblasts. This indicates that the process of agonist-induced receptor internalisation is strongly influenced by cell phenotype and this may have important implications for drug treatment with long-acting b2AR agonists

CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
CMB-S4---the next-generation ground-based cosmic microwave background (CMB)
experiment---is set to significantly advance the sensitivity of CMB
measurements and enhance our understanding of the origin and evolution of the
Universe, from the highest energies at the dawn of time through the growth of
structure to the present day. Among the science cases pursued with CMB-S4, the
quest for detecting primordial gravitational waves is a central driver of the
experimental design. This work details the development of a forecasting
framework that includes a power-spectrum-based semi-analytic projection tool,
targeted explicitly towards optimizing constraints on the tensor-to-scalar
ratio, , in the presence of Galactic foregrounds and gravitational lensing
of the CMB. This framework is unique in its direct use of information from the
achieved performance of current Stage 2--3 CMB experiments to robustly forecast
the science reach of upcoming CMB-polarization endeavors. The methodology
allows for rapid iteration over experimental configurations and offers a
flexible way to optimize the design of future experiments given a desired
scientific goal. To form a closed-loop process, we couple this semi-analytic
tool with map-based validation studies, which allow for the injection of
additional complexity and verification of our forecasts with several
independent analysis methods. We document multiple rounds of forecasts for
CMB-S4 using this process and the resulting establishment of the current
reference design of the primordial gravitational-wave component of the Stage-4
experiment, optimized to achieve our science goals of detecting primordial
gravitational waves for at greater than , or, in the
absence of a detection, of reaching an upper limit of at CL.Comment: 24 pages, 8 figures, 9 tables, submitted to ApJ. arXiv admin note:
