The Theological Method of Friedrich Schleiermacher
What Friedrich Schleiermacher is most known for is his theological method of deriving doctrine from religious experience. He believed that religious piety is to be found in the “feeling of absolute dependence”, and all subsequent doctrines must be discovered through reflection upon religious experience. Understanding and critiquing Schleiermacher’s theological method requires examining his theological influences, his “feeling of absolute dependence,” and a few examples from his systematic theology. In the end, Schleiermacher’s theological method is ingenious but misguided because it is based on a faulty religious epistemology of human experience. What is needed instead is an objective standard of truth from outside of human nature–namely, God’s revelation found in the Bible
Evidence of Late Quaternary Fires from Charcoal and Siliceous Aggregates in Lake Sediments in the Eastern U.S.A.
The late-glacial transition to the Holocene, 15,000–11,600 cal yr BP, is an enigmatic period of dynamic global changes and a major extinction event in North America. Fire is an agent of disturbance that transforms the environment physically and chemically, and affects plant community composition. To improve understanding of the linkages between fire, vegetation, and climate over the late glacial and Holocene in the eastern U.S., I analyzed lake-sediment cores for charcoal and indicators of wood ash, and compared results to existing pollen records. A new microscopic charcoal record from Anderson Pond, Tennessee revealed high fire activity from 23,000–15,000 cal yr BP when conifers dominated, and during the Mid-Holocene Warm Period (8000–5200 cal yr BP), when hardwoods dominated. Macroscopic charcoal analysis of sediments from Pigeon Marsh, Georgia showed high fire activity from 16,500–14,500 cal yr BP, below a major hiatus. Jackson Pond, Kentucky and Cahaba Pond, Alabama had low macroscopic charcoal concentrations during the late glacial; largest charcoal peaks occurred around 5000 cal yr BP at Jackson Pond, and from 1370–640 cal yr BP at Cahaba Pond.
Thin sections were prepared for cores from the four southeastern U.S. sites and from Swift and Slack Lakes, Michigan, and analyzed together with nitrogen isotopes and element data from XRF. Thin sections showed the presence of siliceous aggregates, a unique grain type, in sediments from five sites. These grains are rare, occurring in only three periods, around 19,250, 14,000 and 12,400 cal yr BP. In laboratory experiments, I produced siliceous aggregates from wood ash with simulated rain, and found their formation requires silt, but not high acidity. On the landscape, siliceous aggregates form after fires in wood ash by the action of water. The alkaline pH of the wet ash dissolves phytoliths, and amorphous silica nucleates around silt-sized quartz grains. Then aggregates are transported into lake sediments. My research demonstrates that siliceous aggregates are a new proxy for wildfires in paleoenvironmental records. The wildfire-derived siliceous aggregates in cores examined from the eastern U.S. are contemporaneous with combustion signals in Greenland ice cores, suggesting widespread late-glacial fire events
Factors limiting productivity of the Central Arctic Caribou Herd of Alaska
Many biotic and abiotic factors can limit productivity and growth of caribou (Rangifer tarandus) herds, but limiting factors typically vary by region. Identifying limiting factors may help to indicate which seasons are of relative importance to a caribou herd and possibly to suggest general life history strategies. Using regression techniques, we found that despite previous suggestions, net productivity of Alaska’s Central Arctic Caribou Herd (CAH) did not respond to early summer forage biomass or summer insect severity from the previous year. Abiotic factors that did have apparent effects on CAH productivity included early fall snow deposition, winter snow condition, and spring snow ablation. To achieve a suitable weight for conception, caribou of the CAH may exhibit a seasonal time-minimizing foraging strategy by moderating weight gain during the warm summer insect season and feeding more intensively during the insect-free weeks before the autumn rut. A long-term trend of the Northern Hemisphere annular mode (NAM) may be linked to anthropogenic climate change and may have negative implications for the future success of the CAH
Apathy and its response to antipsychotic review and non-pharmacological interventions in people with dementia living in nursing homes : WHELD, A factorial cluster randomised controlled trial
Objectives: Apathy is common, impactful, and difficult to manage in people with dementia. We evaluated the efficacy of non-pharmacological interventions, exercise and social interaction, in combination with antipsychotic review, to reduce apathy in people with dementia living in nursing homes in a cluster randomised controlled trial (RCT). Methods: Well-being and health for people with dementia (WHELD) programme included a 2X2X2 factorial cluster RCT involving people with dementia living in 16 nursing homes in UK. All homes received training in person-centred care, and were randomised to receive antipsychotic review, social interaction, and exercise, either alone or in combinations. Apathy was one of the secondary outcomes of the WHELD trial, and it was measured by the Neuropsychiatric Inventory-nursing home version at baseline and nine months (N=273). We employed multilevel mixed effects linear regression models to assess the impact of the interventions on apathy. Results: Prevalence of apathy was 44.0% (n=120; 95% CI 38.1-49.9%) at baseline. Severity of apathy had significant positive correlations with dementia severity, neuropsychiatric symptoms, depressive symptoms, agitation, and the needs of the people with dementia (p<0.001). Antipsychotic review reduced antipsychotic use, but it significantly increased apathy (β=5.37; SE=0.91; p<0.001). However, antipsychotic review in combination with either social interaction (β=-5.84; SE=1.15; p<0.001) or exercise (β=-7.54; SE=0.93; p<0.001) significantly reduced apathy. Conclusions: Antipsychotic review can play a significant role in improving apathy in people with dementia living in nursing homes, when combined with psychosocial interventions such as social interaction and exercise. Guidance must be adapted to reflect this subtlety in care
