The Budget Enforcement Act in 1992: Necessary But Not Sufficient

The 1992 budget process followed the Budget Enforcement Act of 1990 (BEA) script, although not without a protracted conflict concerning the walls separating the three categories of discretionary spending. The walls were retained, spending caps were met, and the process was timely. What deficit reduction occurred was the result of spending below the FY 1993 defense cap. Congress neither raised taxes nor cut entitlements to reduce the deficit further. The deficit grew significantly, driven by entitlement spending, chiefly health care programs. The limits of the BEA approach to spending control and deficit reduction became apparent

The metatranscriptomes of root caries and sound root surface biofilms

There is limited knowledge of bacterial metabolism in root caries lesions. The aim of this study was to describe the bacterial metatranscriptomes associated with root caries and sound root surfaces using an RNA-seq analysis approach. The biofilms from exposed root surfaces were sampled from caries-free volunteers (n=10), and from the infected dentine of volunteers with root caries (n=30). Total bacterial RNA was extracted; cDNA libraries were prepared and sequenced on the Illumina Hi-Seq2500. The function and composition of the metabolically active microbiota were investigated using: a) MG-RAST, and b) denovo assembly of the read data and mapping to contigs. Differential gene expression analysis was done using the R package DESeq2 (padj <10−3). Transcripts with the highest expression levels were those coding for membrane transport systems, ribosomal proteins, enolase and glycolytic pathways in both groups. Differential analysis indicated that genes coding for the OmpA domain protein and metalloprotease domain protein were over-expressed in the caries samples (log2FoldChange = –12.2; padj= 3.5 × 10−13), whereas genes in the samples from healthy sites over-expressed pilus biosynthesis protein, thiamine diphosphokinase and transporter protein (log2FoldChange = 16.5; padj = 2.2 × 10−21). Metatranscriptomic analyses show unique gene expression profiles in sound root surface and carious biofilms

Restorative Justice Cases in Scotland:Factors Related to Participation, the Restorative Process, Agreement Rates and Forms of Reparation

This research draws on four years of data from three restorative justice services in Scotland to explore the factors associated with service user participation, agreement rates, the use of direct or indirect restorative processes, and different forms of reparation. Among other things, the results show that participation is more likely if the accused is contacted before the victim, if the alleged offence involves vandalism, and if the accused is male or young or does not have a recorded history of offending. The results suggest that, given appropriate ethical and safety considerations, the default practice should be to approach the accused first. The implications of the results are discussed within a theoretical framework

Ecological and Genomic Attributes of Novel Bacterial Taxa That Thrive in Subsurface Soil Horizons.

While most bacterial and archaeal taxa living in surface soils remain undescribed, this problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in the subsurface. Additionally, previous studies of soil microbiomes have focused almost exclusively on surface soils, even though the microbes living in deeper soils also play critical roles in a wide range of biogeochemical processes. We examined soils collected from 20 distinct profiles across the United States to characterize the bacterial and archaeal communities that live in subsurface soils and to determine whether there are consistent changes in soil microbial communities with depth across a wide range of soil and environmental conditions. We found that bacterial and archaeal diversity generally decreased with depth, as did the degree of similarity of microbial communities to those found in surface horizons. We observed five phyla that consistently increased in relative abundance with depth across our soil profiles: Chloroflexi, Nitrospirae, Euryarchaeota, and candidate phyla GAL15 and Dormibacteraeota (formerly AD3). Leveraging the unusually high abundance of Dormibacteraeota at depth, we assembled genomes representative of this candidate phylum and identified traits that are likely to be beneficial in low-nutrient environments, including the synthesis and storage of carbohydrates, the potential to use carbon monoxide (CO) as a supplemental energy source, and the ability to form spores. Together these attributes likely allow members of the candidate phylum Dormibacteraeota to flourish in deeper soils and provide insight into the survival and growth strategies employed by the microbes that thrive in oligotrophic soil environments.IMPORTANCE Soil profiles are rarely homogeneous. Resource availability and microbial abundances typically decrease with soil depth, but microbes found in deeper horizons are still important components of terrestrial ecosystems. By studying 20 soil profiles across the United States, we documented consistent changes in soil bacterial and archaeal communities with depth. Deeper soils harbored communities distinct from those of the more commonly studied surface horizons. Most notably, we found that the candidate phylum Dormibacteraeota (formerly AD3) was often dominant in subsurface soils, and we used genomes from uncultivated members of this group to identify why these taxa are able to thrive in such resource-limited environments. Simply digging deeper into soil can reveal a surprising number of novel microbes with unique adaptations to oligotrophic subsurface conditions

The Higher Spin/Vector Model Duality

This paper is mainly a review of the dualities between Vasiliev's higher spin gauge theories in AdS4 and three dimensional large N vector models, with focus on the holographic calculation of correlation functions of higher spin currents. We also present some new results in the computation of parity odd structures in the three point functions in parity violating Vasiliev theories.Comment: 55 pages, 1 figure. Contribution to J. Phys.
