Providing Medication Assisted Treatment for Opioid Use Disorder in Family Medicine Clinics in Vermont

Opioid use disorder is a nationwide issue and a serious problem in the state of Vermont. Medication assisted treatment (MAT) is currently being used to treat individuals with opioid use disorder. In an effort to address the opioid epidemic, more and more family medicine physicians in Vermont are becoming trained medication assisted treatment providers. This project aims to recognize some of the challenges faced by physicians who are currently prescribing MAT in family medicine clinics, as well as to identify the concerns of family medicine physicians who are not currently prescribing MAT. By determining barriers to providing MAT to patients with opioid use disorder in family medicine clinics, additional support and resources can be identified and implemented.https://scholarworks.uvm.edu/fmclerk/1198/thumbnail.jp

Lake Champlain Water Quality: A Study of Public Awareness, Perceptions, and Behavior

Introduction: Lake Champlain serves as a major source of drinking water and a prime recreational area in Vermont. The Vermont Department of Health actively monitors Lake Champlain water quality, generates informational resources, and issues restrictions and advisories as necessary. Key water quality issues include: blue-green algae blooms (BGAB), combined sewer overflow (CSO), mercury-based fish consumption advisories, and suitability for recreational use. Determining public awareness of Lake Champlain water quality, and how perceptions of Lake Champlain water quality influence behavior, are essential to improving communication with at-risk and underinformed populations.https://scholarworks.uvm.edu/comphp_gallery/1233/thumbnail.jp

Seismic structure of the Endeavour Segment, Juan de Fuca Ridge : correlations with seismicity and hydrothermal activity

The definitive version was published in Journal of Geophysical Research 112 (2007): B02401, doi:10.1029/2005JB004210.Multichannel seismic reflection data collected in July 2002 at the Endeavour Segment, Juan de Fuca Ridge, show a midcrustal reflector underlying all of the known high-temperature hydrothermal vent fields in this area. On the basis of the character and geometry of this reflection, its similarity to events at other spreading centers, and its polarity, we identify this as a reflection from one or more crustal magma bodies rather than from a hydrothermal cracking front interface. The Endeavour magma chamber reflector is found under the central, topographically shallow section of the segment at two-way traveltime (TWTT) values of 0.9–1.4 s (∼2.1–3.3 km) below the seafloor. It extends approximately 24 km along axis and is shallowest beneath the center of the segment and deepens toward the segment ends. On cross-axis lines the axial magma chamber (AMC) reflector is only 0.4–1.2 km wide and appears to dip 8–36° to the east. While a magma chamber underlies all known Endeavour high-temperature hydrothermal vent fields, AMC depth is not a dominant factor in determining vent fluid properties. The stacked and migrated seismic lines also show a strong layer 2a event at TWTT values of 0.30 ± 0.09 s (380 ± 120 m) below the seafloor on the along-axis line and 0.38 ± 0.09 s (500 ± 110 m) on the cross-axis lines. A weak Moho reflection is observed in a few locations at TWTT values of 1.9–2.4 s below the seafloor. By projecting hypocenters of well-located microseismicity in this region onto the seismic sections, we find that most axial earthquakes are concentrated just above the magma chamber and distributed diffusely within this zone, indicating thermal-related cracking. The presence of a partially molten crustal magma chamber argues against prior hypotheses that hydrothermal heat extraction at this intermediate spreading ridge is primarily driven by propagation of a cracking front down into a frozen magma chamber and indicates that magmatic heat plays a significant role in the hydrothermal system. Morphological and hydrothermal differences between the intermediate spreading Endeavour and fast spreading ridges are attributable to the greater depth of the Endeavour AMC and the corresponding possibility of axial faulting.E.V.A. was supported by a National Science Foundation Graduate Research Fellowship, the WHOI-MIT Joint Program, and the WHOI Deep Ocean Exploration Institute.

Public Information and Performance: The Role of Spatial Dependence in the Worldwide Governance Indicators among African Countries

The Worldwide Governance Indicators (WGI) provide transparent and comparable country statistics for different dimensions of governance linked to (under)development. Yet, does the public availability of governance data actually enhance performance? If investors, donor agencies, and citizens are made aware of relative governance performance, competition for inward investment, such as FDI and ODA, and domestic legitimacy become plausible mechanisms for diffusion of good governance. We test whether such mechanisms operate using the WGI for Africa, and find evidence for spatial diffusion of democracy, rule of law, and corruption control. There is no evidence for diffusion of regulatory quality and government effectiveness

Surviving elections: election violence, incumbent victory, and post-election repercussions

It is often assumed that government-sponsored election violence increases the probability that incumbent leaders remain in power. Using cross-national data, we show that election violence increases the probability of incumbent victory, but can generate risky post-election dynamics. These differences in the consequences of election violence reflect changes in the strategic setting over the course of the election cycle. In the pre-election period, anti-incumbent collective action tends to be focused on the election itself, either through voter mobilization or opposition-organized election boycotts. In the post-election period, by contrast, when a favorable electoral outcome is no longer a possibility, anti-government collective action more often takes the form of mass political protest, which in turn can lead to costly repercussions for incumbent leaders

Growth aspirations and social capital:young firms in a post-conflict environment

This article explores the growth aspirations of owners and managers of young firms in a post-conflict economy by focusing on social capital. It treats social capital as a multidimensional, multilevel phenomenon, studying the effects of discussion network characteristics, trust in institutions, generalised trust in people and local ethnic pluralism. We argue that in a post-conflict country, ethnic pluralism is indicative of local norms of tolerance towards experimentation and risk taking which support growth aspirations. It also distinguishes between the aspirations of hired managers and owners-managers. The empirical counterpart and hypotheses testing rely on survey evidence drawn from young businesses in Bosnia and Herzegovina

MIGHTEE-HI: The first MeerKAT HI mass function from an untargeted interferometric survey

We present the first measurement of the HI mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MIGHTEE Survey Early Science data covering a period of approximately a billion years ($0 \leq z \leq 0.084$). This is the first HIMF measured using interferometric data over non-group or cluster field, i.e. a deep blank field. We constrain the parameters of the Schechter function which describes the HIMF with two different methods: $1/\rm V_{\rm max}$ and Modified Maximum Likelihood (MML). We find a low-mass slope $\alpha=-1.29^{+0.37}_{-0.26}$, `knee' mass $\log_{10}(M_{*}/{\rm M_{\odot}}) = 10.07^{+0.24}_{-0.24}$ and normalisation $\log_{10}(\phi_{*}/\rm Mpc^{-3})=-2.34^{+0.32}_{-0.36}$ ($H_0 = 67.4$ kms$^{-1}$ Mpc$^{-1}$) for $1/\rm V_{\rm max}$ and $\alpha=-1.44^{+0.13}_{-0.10}$, `knee' mass $\log_{10}(M_{*}/{\rm M_{\odot}}) = 10.22^{+0.10}_{-0.13}$ and normalisation $\log_{10}(\phi_{*}/\rm Mpc^{-3})=-2.52^{+0.19}_{-0.14}$ for MML. When using $1/\rm V_{\rm max}$ we find both the low-mass slope and `knee' mass to be consistent within $1\sigma$ with previous studies based on single-dish surveys. The cosmological mass density of HI is found to be slightly larger than previously reported: $\Omega_{\rm HI}=5.46^{+0.94}_{-0.99} \times 10^{-4}h^{-1}_{67.4}$ from $1/\rm V_{\rm max}$ and $\Omega_{\rm HI}=6.31^{+0.31}_{-0.31} \times 10^{-4}h^{-1}_{67.4}$ from MML but consistent within the uncertainties. We find no evidence for evolution of the HIMF over the last billion years.Comment: 13 pages, 9 figures, accepted for publication in MNRA

Hydrothermally-induced melt lens cooling and segmentation along the axis of fast- and intermediate-spreading centers

Author Posting. © American Geophysical Union, 2011. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Geophysical Research Letters 38 (2011): L14307, doi:10.1029/2011GL047798.The heat output and thermal regime of fast and intermediate spreading centers are strongly controlled by boundary layer processes between the hydrothermal system and the underlying crustal magma chamber (AMC), which remain to be fully understood. Here, we model the interactions between a shallow two-dimensional cellular hydrothermal system at temperatures <700°C, and a deeper AMC at temperatures up to 1200°C. We show that hydrothermal cooling can freeze the AMC in years to decades, unless melt injections occur on commensurate timescales. Moreover, the differential cooling between upflow and downflow zones can segment the AMC into mush and melt regions that alternate on sub-kilometric length scales. These predictions are consistent with along-axis variations in AMC roof depth observed in ophiolites and oceanic settings. In this respect, fine-scale geophysical investigations of the structure of AMCs may help constrain hydrothermal recharge locations associated with active hydrothermal sites

Climate, conflict and forced migration

Despite the lack of robust empirical evidence, a growing number of media reports attempt to link climate change to the ongoing violent conflicts in Syria and other parts of the world, as well as to the migration crisis in Europe. Exploiting bilateral data on asylum seeking applications for 157 countries over the period 2006–2015, we assess the determinants of refugee flows using a gravity model which accounts for endogenous selection in order to examine the causal link between climate, conflict and forced migration. Our results indicate that climatic conditions, by affecting drought severity and the likelihood of armed conflict, played a significant role as an explanatory factor for asylum seeking in the period 2011–2015. The effect of climate on conflict occurrence is particularly relevant for countries in Western Asia in the period 2010–2012 during when many countries were undergoing political transformation. This finding suggests that the impact of climate on conflict and asylum seeking flows is limited to specific time period and contexts
