Subjective well-being and consumption: defining the relationship and exploring the effects of overconsumption
Master in Economics: Empirical Applications and Policies. Academic Year 2022/23.Previous economic studies on subjective well-being have primarily focused on income, and limited research has been conducted on the relationship between consumption and subjective well-being, which lies at the core of economic theory. This paper explores the effect of consumption on life satisfaction, using a new synthetic dataset with information on subjective well-being and consumption for Spanish households. The relationship between consumption and life satisfaction, and levels of consumption are analyzed with multiple linear regressions, while a semiparametric approach is applied through a generalized additive model (GAM). The instrumental variable approach does not confirm the presence of endogeneity, however the similarity of results from multiple approaches (GAM and linear regressions) may indicate a low severity of the issue of endogeneity in this model. This paper finds a concave curve defining the relationship between consumption and life satisfaction in both the linear regressions and the semi-parametric approach, representing a decreasing marginal effect of consumption
Which treatments provide the most relief for pharyngitis pain?
Nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, antibiotics, and oral and intramuscular steroids are effective (strength of recommendation [SOR]: A, meta-analysis). Ibuprofen relieves pain more effectively than acetaminophen (SOR: A, meta-analysis). Antibiotics reduce pain in confirmed bacterial infections (SOR: A, multiple randomized controlled trials [RCTs]). Steroids are superior to placebo (SOR: A, meta-analysis). Traditional demulcents, agents that help form a film over mucous membranes, provide less than 30 minutes of pain relief (SOR: B, small RCT); demulcents that contain benzocaine or lidocaine are longer acting (SOR: B, small RCT). The efficacy of herbal remedies can't be determined because of lack of high-quality studies (SOR: A, meta-analysis). Zinc doesn't reduce pharyngitis symptoms (SOR: A, meta-analysis)
Use of Riparian Vegetated Filter Strips to Reduce Nitrate and Fecal Contamination in Surface Water
This research assessed fecal bacteria trapping in surface runoff by grass filters and their potential to enhance NO3- removal via denitrification. Grass filter strips 9.0 m long trapped over 99% of the soil in surface runoff in 1992. Fecal coliform removal was less than 75%. In 1993, 9.0 and 4.5 m grass filter strips trapped 99 and 95% of the sediment, respectively. Fecal coliform trapping efficiency was 90% in 9.0 m grass filters and 75% in 4.5 m filters. Fecal streptococci trapping efficiency was 77% in 9.0 m grass filters and only 56% in 4.5 m filters. Fecal coliform concentration in grass filter strip runoff consistently exceeded 200 fecal coliforms per 100 mL. Grass filter strips which minimized sediment loss did not reduce fecal contamination of water to acceptable levels when runoff occurred. Nitrous oxide fluxes were smaller in grass filters than in manured plots. In 1993, N2O loss ranged from 2050 to 11120 mg N2O-N m-2 h-1 in amended soil and 160 to 1060 mg N2O-N m-2 h-1 in grass filter strips. Denitrification was not apparently enhanced in the grass filters relative to the manured soil
Nuevas Vistas
With the new database system in place, the electronic resources page is much easier to update and maintain. In addition, the tagging system has allowed users to find the resources they need in a more efficient manner. Future plans include using the new electronic resources database to create self generating subject guides for different departments within the division of health sciences
A genome-wide association study for diabetic nephropathy genes in African Americans
A genome-wide association study was performed using the Affymetrix 6.0 chip to identify genes associated with diabetic nephropathy in African Americans. Association analysis was performed adjusting for admixture in 965 type 2 diabetic African American patients with end-stage renal disease (ESRD) and in 1029 African Americans without type 2 diabetes or kidney disease as controls. The top 724 single nucleotide polymorphisms (SNPs) with evidence of association to diabetic nephropathy were then genotyped in a replication sample of an additional 709 type 2 diabetes-ESRD patients and 690 controls. SNPs with evidence of association in both the original and replication studies were tested in additional African American cohorts consisting of 1246 patients with type 2 diabetes without kidney disease and 1216 with non-diabetic ESRD to differentiate candidate loci for type 2 diabetes-ESRD, type 2 diabetes, and/or all-cause ESRD. Twenty-five SNPs were significantly associated with type 2 diabetes-ESRD in the genome-wide association and initial replication. Although genome-wide significance with type 2 diabetes was not found for any of these 25 SNPs, several genes, including RPS12, LIMK2, and SFI1 are strong candidates for diabetic nephropathy. A combined analysis of all 2890 patients with ESRD showed significant association SNPs in LIMK2 and SFI1 suggesting that they also contribute to all-cause ESRD. Thus, our results suggest that multiple loci underlie susceptibility to kidney disease in African Americans with type 2 diabetes and some may also contribute to all-cause ESRD
Integrative Taxonomy for Continental-Scale Terrestrial Insect Observations
Although 21st century ecology uses unprecedented technology at the largest spatio-temporal scales in history, the data remain reliant on sound taxonomic practices that derive from 18th century science. The importance of accurate species identifications has been assessed repeatedly and in instances where inappropriate assignments have been made there have been costly consequences. The National Ecological Observatory Network (NEON) will use a standardized system based upon an integrative taxonomic foundation to conduct observations of the focal terrestrial insect taxa, ground beetles and mosquitoes, at the continental scale for a 30 year monitoring program. The use of molecular data for continental-scale, multi-decadal research conducted by a geographically widely distributed set of researchers has not been evaluated until this point. The current paper addresses the development of a reference library for verifying species identifications at NEON and the key ways in which this resource will enhance a variety of user communities
Exploring Green Nudges: Using Local Group Identity to Reduce Beef Consumption on Campus
Beef production is a large driver of environmental problems, from greenhouse gas emissions and
deforestation to air pollution and water contamination (FAO, 2006; EPA, 2003). This paper
explores how beef consumption can be reduced, and evaluates an intervention based on Ajzen’s
(1985) Theory of Planned Behavior (TPB), targeting beef consumption on Princeton University’s
campus. More specifically, I compare nudges appealing to local group identity and global
identity in terms of their effectiveness in reducing beef consumption in a natural dining hall
setting. The results show no significant difference between the global and local identity
condition. However, a lower average beef consumption was found in the experimental conditions
compared to baseline data. Individual behaviors can be large drivers of environmental
destruction, and a better understanding of the mechanisms underlying these behaviors will be
important in reducing the global impacts of ERBs
