Language of Lullabies: The Russification and De-Russification of the Baltic States

This article argues that the laws for promotion of the national languages are a legitimate means for the Baltic states to establish their cultural independence from Russia and the former Soviet Union

Enhanced Water Quality Protection in Florida: An Analysis of the Regulatory and Practical Significance of an Outstanding Florida Water Designation

The Outstanding Florida Water (OFW) designation is the highest protection offered to a body of water by the state of Florida and is available only to those waters whose “natural attributes” warrant it. An OFW designation provides that water body with an antidegradation standard for certain activities affecting its water quality. Ordinarily, waters in Florida must meet the criteria established by rule for their respective class of water (based on the Florida water body classification system), regardless of existing water quality. Once a water body is designated as an OFW, however, a baseline water quality standard is set based on the ambient water quality of that particular water body. Because the OFW water quality standard may be higher than the rule-based water quality classification criteria, regulated activities that may affect the OFW are subject to additional scrutiny by regulatory agencies. In addition, those activities not necessarily occurring within an OFW, but that may “significantly degrade” an OFW, are subject to heightened scrutiny. The ability of current OFW regulation to fulfill the legislative intent behind the OFW designation remains uncertain. Judicial and administrative case law addressing OFWs provide little clear guidance in interpreting the statutory standards for the issuance of permits in or affecting OFWs, especially the “clearly in the public interest” standard. The Florida Department of Environmental Protection (FDEP) should consider adopting for the OFW Program the type of public interest benefits/costs balancing test currently provided for in Aquatic Preserves Program rules. This test creates a discernible distinction between the public interest standard for submerged lands activities that are within aquatic preserves as opposed to those occurring outside of the preserves. The effect of the OFW designation on water quality parameters subject to a narrative standard (nutrients), and on water quality parameters that are not currently established by rule (e.g. emerging pathogens of concern) has not been established. In addition OFWs do not appear to enjoy any special consideration as designated uses subject to impaired waters restoration. The definitions of non-degradation and of ambient water quality for the purposes of OFW designation should be amended to ensure that they contemplate degradation by contaminants other than the current rule–based list of water quality standards and criteria. The extent to which Best Management Practices (BMPs) for silviculture operations are sufficient to safeguard OFW water quality may require further research. In addition, the extent to which the OFW statute and rules recognize the ecological role and recreational value of riparian zones remains in question. This should be clarified by the FDEP

Theory of adsorbate induced surface reconstruction on W(100)

We report results of a theoretical study on an adsorbate induced surface reconstruction. Hydrogen adsorption on a W(100) surface causes a switching transition in the symmetry of the displacements of the W atoms within the ordered c(2x2) phase. This transition is modeled by an effective Hamiltonian, where the hydrogen degrees of freedom are integrated out. Based on extensive Monte Carlo renormalisation group calculations we show that the switching transition is of second order at high temperatures and of first order at low temperatures. This behavior is qualitatively explained in terms of an XY model where there is an interplay between four and eight fold anisotropy fields. We also compare the calculated phase diagrams with a simple mean field theory.Comment: CSC Preprint, 31 pages (plain TeX file, no figures

Effective Field Theories and Inflation

We investigate the possible influence of very-high-energy physics on inflationary predictions focussing on whether effective field theories can allow effects which are parametrically larger than order H^2/M^2, where M is the scale of heavy physics and H is the Hubble scale at horizon exit. By investigating supersymmetric hybrid inflation models, we show that decoupling does not preclude heavy-physics having effects for the CMB with observable size even if H^2/M^2 << O(1%), although their presence can only be inferred from observations given some a priori assumptions about the inflationary mechanism. Our analysis differs from the results of hep-th/0210233, in which other kinds of heavy-physics effects were found which could alter inflationary predictions for CMB fluctuations, inasmuch as the heavy-physics can be integrated out here to produce an effective field theory description of low-energy physics. We argue, as in hep-th/0210233, that the potential presence of heavy-physics effects in the CMB does not alter the predictions of inflation for generic models, but does make the search for deviations from standard predictions worthwhile.Comment: 19 pages, LaTeX, no figures, uses JHEP

Deep sequencing analysis of the developing mouse brain reveals a novel microRNA

Extent: 15p.Background: MicroRNAs (miRNAs) are small non-coding RNAs that can exert multilevel inhibition/repression at a post-transcriptional or protein synthesis level during disease or development. Characterisation of miRNAs in adult mammalian brains by deep sequencing has been reported previously. However, to date, no small RNA profiling of the developing brain has been undertaken using this method. We have performed deep sequencing and small RNA analysis of a developing (E15.5) mouse brain. Results: We identified the expression of 294 known miRNAs in the E15.5 developing mouse brain, which were mostly represented by let-7 family and other brain-specific miRNAs such as miR-9 and miR-124. We also discovered 4 putative 22-23 nt miRNAs: mm_br_e15_1181, mm_br_e15_279920, mm_br_e15_96719 and mm_br_e15_294354 each with a 70-76 nt predicted pre-miRNA. We validated the 4 putative miRNAs and further characterised one of them, mm_br_e15_1181, throughout embryogenesis. Mm_br_e15_1181 biogenesis was Dicer1-dependent and was expressed in E3.5 blastocysts and E7 whole embryos. Embryo-wide expression patterns were observed at E9.5 and E11.5 followed by a near complete loss of expression by E13.5, with expression restricted to a specialised layer of cells within the developing and early postnatal brain. Mm_br_e15_1181 was upregulated during neurodifferentiation of P19 teratocarcinoma cells. This novel miRNA has been identified as miR-3099. Conclusions: We have generated and analysed the first deep sequencing dataset of small RNA sequences of the developing mouse brain. The analysis revealed a novel miRNA, miR-3099, with potential regulatory effects on early embryogenesis, and involvement in neuronal cell differentiation/function in the brain during late embryonic and early neonatal development.King-Hwa Ling, Peter J Brautigan, Christopher N Hahn, Tasman Daish, John R Rayner, Pike-See Cheah, Joy M Raison, Sandra Piltz Jeffrey R Mann, Deidre M Mattiske, Paul Q Thomas, David L Adelson and Hamish S Scot
