Death Notification for the Law Enforcement Chaplain; Considering Models that Emphasize the Ministry of Presence

Against a backdrop of protocols developed in the medical community for delivering bad news (news of a distressing nature) to patients and survivors (e.g., friends and family of a patient or victim), a straightforward procedure is described for law enforcement chaplains who must deliver death notifications to civilians. A description of and appreciation for the ministry of presence is explored. Specifically, the ministry of presence, modeled after Jesus’ example in the Incarnation and His development of disciples, is described as the cornerstone of chaplaincy

Cerebrovascular Dysfunction in Metabolic Syndrome and Depression: Mechanisms and Implications for Neurovascular Disease

Cerebrovascular diseases are any pathological conditions that are caused by disruptions or alterations in the blood supply to the brain. The brain, which is only 2% of body mass, constantly requires a minimum of 20% of cardiac output to meet its unique metabolic demands. Cerebral tissue relies on aerobic respiration and therefore requires a constant, steady supply of blood to provide oxygen and glucose to make ATP. Insufficient perfusion of the brain, which occurs as a result of reduced or obstructed blood flow, results in cerebral ischemia; ischemic neurons quickly deplete their available ATP and die if blood flow is not restored. Disruptions in the delivery of blood to the brain, either acutely or chronically, can lead to impairment of neurological function, neuronal cell death, and even death.;Metabolic Syndrome (MetSyn) is the comorbid presence of three or more risk factors, including: central obesity, hypertriglyceridemia, high cholesterol, hypertension, and hyperglycemia. Data from the NHANES study reports that over 35% of all adults, and over 50% of adults over 60, are estimated to have MetSyn. MetSyn is a risk factor for almost every major cardiovascular disease, and causes well-defined impairments in the peripheral circulation. However, its effects on regulation of cerebral blood flow are not well understood. The primary aim of this dissertation is to study the functional and structural alterations cause by MetSyn in the cerebral circulation, utilizing the obese Zucker rat (OZR), a translationally relevant model for studying the vascular complications of MetSyn, and to interrogate how vascular and neurological outcomes to cerebrovascular disruptions are influenced by pre-existing cerebral vasculopathies associated with MetSyn in OZR. The specific aims are as follows:;1. Define and characterize structural and functional changes in vascular reactivity, vessel wall mechanics, and vascular remodeling in middle cerebral arteries (MCA) of OZR, and evaluate changes in microvascular density throughout the cerebral microcirculation.;2. Determine the contribution of each constituent pathology of MetSyn on the development of cerebrovascular impairments in OZR, and identify mechanisms through which these pathologies are progressing in the cerebral circulation.;3. Interrogate the mechanisms of stroke-induced vascular dysfunction in lean Zucker (LZR) and OZR, and determine how pre-existing vascular dysfunction in OZR changes outcomes and pathological mechanisms following ischemic stroke.;4. Investigate the effects of chronic stress/ depression on cerebrovascular function in LZR and OZR, assess efficacy of exercise as a prophylactic anti-depressant treatment, and evaluate mechanisms through which impairments, and exercise-based recovery, are occurring.;The results of these studies have helped to establish the prominent driving mechanism of cerebrovascular dysfunction in MetSyn, and defined the functional impacts these impairments have on outcomes to ischemic stroke and stress-induced depression. By thoroughly interrogating these mechanisms and evaluating functional outcomes of relevant disease states, this dissertation hopes to lay the groundwork for a new approach to understanding the relationship between MetSyn, cerebrovascular dysfunction, and neurological outcomes

Short-term Response of Holcus lanatus L. (Common Velvetgrass) to Chemical and Manual Control at Yosemite National Park, USA

One of the highest priority invasive species at both Yosemite and Sequoia and Kings Canyon national parks is Holcus lanatus L. (common velvetgrass), a perennial bunchgrass that invades mid-elevation montane meadows. Despite velvetgrass being a high priority species, there is little information available on control techniques. The goal of this project was to evaluate the short-term response of a single application of common chemical and manual velvetgrass control techniques. The study was conducted at three montane sites in Yosemite National Park. Glyphosate spotspray treatments were applied at 0.5, 1.0, 1.5, and 2.0% concentrations, and compared with hand pulling to evaluate effects on cover of common velvetgrass, cover of other plant species, and community species richness. Posttreatment year 1 cover of common velvetgrass was 12.1% 6 1.6 in control plots, 6.3% 6 1.5 averaged over the four chemical treatments (all chemical treatments performed similarly), and 13.6% 6 1.7 for handpulled plots. This represents an approximately 50% reduction in common velvetgrass cover in chemically- treated plots recoded posttreatment year 1 and no statistically significant reduction in hand pulled plots compared with controls. However, there was no treatment effect in posttreatment year 2, and all herbicide application rates performed similarly. In addition, there were no significant treatment effects on nontarget species or species richness. These results suggest that for this level of infestation and habitat type, (1) one year of hand pulling is not an effective control method and (2) glyphosate provides some level of control in the short-term without impact to nontarget plant species, but the effect is temporary as a single year of glyphosate treatment is ineffective over a twoyear period

Analytical procedures and interpretation basis for biomarkers used in environmental effect monitoring for the water column at the Norwegian continental shelf

Prosjektleder Jonny BeyerHerein, method description documents for the biomarker parameters that are required or recommended by the current edition of the guidelines for offshore water column monitoring at the Norwegian shelf (M-300, revised version 2020) are systemised, examined and discussed. The objective of this study is to assess the quality status of open and available method and analysis descriptions, identify any significant shortages on biomarker method descriptions and method validation issues and to discuss/suggest possible correcting and improving measures.Offshore Norge (formerly NOROG, Norwegian Oil and gas)publishedVersio

Water Column Monitoring Research and development programme: Determining the residency of wild fish around offshore installations

Prosjektleder: Steven BrooksIn order to link effects with exposure, recent WCM programmes have discovered the need to determine the residency of fish, caught from within the safety zone of offshore installations. The method of using baited tags to encourage the voluntary ingestion of acoustic tags was thought promising and work was commissioned to develop the baited tag concept for field application. Acoustic telemetry products such as receivers and tag transmitters were obtained from the Norwegian electronics manufacturer Thelma Biotel AS. Developmental work, consisting of a series of cod feeding experiments in large aquaria at the NIVA marine research station in Solbergstrand, discovered some important findings including food preferences, residency time of the tag in the stomach of the fish and excretion pathways. A field trial was conducted in the Trondheimsfjord and although only one tag was eaten the quality of the data was promising for offshore application. The good quality images from the underwater camera with light fixed to the fishing line was also considered suitable for species determination and able to visually document the interactions of the baited tags with the fish. The offshore trial of the baited tag system at Ekofisk proved to be unsuccessful due to the unsuitability of the two fish species present at Ekofisk. It was thought the baited tag system would be more suitable in deeper waters with more voracious fish such as ling, tusk and larger haddock or cod. The baited tag system will be carefully considered for future water column monitoring campaigns.Offshore Norway, represented by EquinorpublishedVersio

Ultrasonic biaxial stress measurement for evaluating the adequacy of gusset plates

The collapse of the I-35W bridge in Minneapolis, Minnesota, on August 1, 2007, resulted in the deaths of 13 people. In an investigation conducted by the National Transportation Safety Board, the cause of the collapse was determined to be the failure of an overstressed steel gusset plate which connected key members of the structure. Following the collapse, State Departments of Transportation sought to confirm the adequacy of gusset plates in other bridges to ensure overstressed gusset plates were not present. Total stresses in a gusset plate cannot be effectively determined using conventional tools such as strain gages. The goal of this research was to improve the safety of steel truss highway bridges by developing an ultrasonic stress measurement methodology for determining total stress in steel gusset plates. A methodology was developed and assessed based on the results of laboratory testing in which the accuracy and precision of ultrasonic stress measurements for a biaxial stress condition were evaluated. This research utilized the acoustoelastic effect to evaluate total stress levels by assessing the acoustic birefringence in steel. The birefringence measurement evaluates normalized variations of polarized shear waves propagating through the plate thickness; these shear waves vary proportionally as a function of stress. A sine regression technique was applied to measure the desired birefringence parameters. Testing results indicated stress measurement uncertainties of 2,600 psi (12.5% of the shear yield strength) or less. This study demonstrated the potential of the sine regression technique to accurately and repeatedly assess total stress levels in steel gusset plates

Discrimination, Coping, and Depression among Black Men Who Have Sex with Men

Black men who have sex with men (BMSM) have elevated risk for depression compared to the general population. BMSM’s capacity to cope with these experiences is not well understood. Increased understanding of how multiple forms of discrimination contribute to depression and how BMSM cope with discrimination can better inform interventions. Data come from 3,510 BMSM who attended Black Pride events in six U.S. cities from 2015-2017. Participants completed a health survey that ascertained their psychosocial health and resiliency profiles. Using multivariable logistic regression models, we tested the associations between type-specific discrimination (race, sexuality, HIV status) and depression. We then conducted sub-analyses to determine if coping attenuated the association between type-specific discrimination and depression. Our findings indicated that increased odds of depression among BMSM were associated with discrimination based on race (aOR=1.38, 95% CI = 1.08-1.76), sexual orientation (aOR=1.32, 95% CI = 1.01-1.72), and HIV status (aOR=1.53, 95% CI = 1.08-2.17). Sub-analyses indicated coping had inconsistent moderation effects between type-specific discrimination and depression. Our findings demonstrate that impact of various forms of discrimination on BMSM’s mental health and the mitigating role of coping. Interventions should seek to address depression by reducing experiences of discrimination and building coping resiliency
