description: ￼￼OBJECTIVE: Alcohol and other drug use appears to reduce decision-making ability and increase the risk of unsafe sex, leading to possible unplanned pregnancies, sexually transmitted diseases/human immunodeficiency virus/HIV transmission, and multiple sexual partners. This study aimed to test the hypothesis that risky sexual behaviors among adolescents are associated with legal and illegal drug use. METHODS: A national cross-sectional survey of 17,371 high-school students was conducted in 2010. Students were selected from 789 public and private schools in each of the 27 Brazilian state capitals by a multistage probabilistic sampling method and answered a self-report questionnaire. Weighted data were analyzed through basic contingency tables and logistic regressions testing for differences in condom use among adolescents who were sexually active during the past month.￼￼ RESULTS: Approximately one third of the high school students had engaged in sexual intercourse in the month prior to the survey, and nearly half of these respondents had not used a condom. While overall sexual intercourse was more prevalent among boys, unsafe sexual intercourse was more prevalent among girls. Furthermore, a lower socioeconomic status was directly associated with non-condom use, while binge drinking and illegal drug use were independently associated with unsafe sexual intercourse. ￼CONCLUSION: Adolescent alcohol and drug use were associated with unsafe sexual practices. School prevention programs must include drug use and sexuality topics simultaneously because both risk-taking behaviors occur simultaneously.
The upper cretaceous Horseshoe Canyon formation: using palesols to reconstruct ancient environments, climates, and record of sea level change in a dinosaur-dominated terrestrial ecosystem

description: Bibliography: p. 117-126
description: Paleosols are investigated to reconstruct Late Cretaceous paleoenvironments and paleoclimates of the Horseshoe Canyon Formation. Based on hydrology, degree of development, and pedogenic features, paleosols record the transition from wetland environments to well-drained environments and back to poorly-drained environments through the formation. Paleoclimatic reconstructions indicate that the lower half of the formation was warm and humid, but a period of cooling and drying occurred in the middle of the formation. A complex relationship exists between paleoenvironmental and paleoclimatic changes and a terrestrial vertebrate faunal turnover within the Horseshoe Canyon Formation. The distribution of paleosols was also compared to sequence stratigraphic interpretations of the HCFm to determine if paleosols recorded evidence of base level changes. Although HCFm paleosols do record some marine transgressive-regressive cycles, the ability to resolve these cycles depends on the distance to the shoreline and the magnitude of the sea­level change.
Reassessing the Critical Legal Studies Movement

subject: FOS: Law

description: Like liberation theologians in seminaries, social medicine proponents in medical schools, radical deconstructionists in university literature departments, and opposition postmodern critics in the arts, critical legal theorists fundamentally question the dominant and usually liberal paradigms prevalent and pervasive
in American culture and society. This thorough questioning is not primarily a constructive attempt to put forward a conception of a new legal and social order. Rather, it is a pronounced disclosure of the inconsistencies, incoherences, silences, and blindness of legal formalists, legal positivists, and legal realists in the liberal tradition. Critical legal studies is more a concerted attack and assault on the legitimacy and authority of pedagogical strategies in law schools than a comprehensive
announcement of what a credible and realizable new society and legal system would look like.

description: © 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. Aphasia is a significant cause of disability and reduced quality of life. Two speech pathology treatment approaches appear efficacious: multimodal and constraint-induced aphasia therapies. In constraint-induced therapies, non-verbal actions (e.g., gesture, drawing) are believed to interfere with treatment and patients are therefore constrained to speech. In contrast, multimodal therapies employ non-verbal modalities to cue word retrieval. Given the clinical and theoretical implications, a comparison of these two divergent treatments was pursued. This systematic review investigated both approaches in chronic aphasia at the levels of impairment, participation and quality of life. After a systematic search, the level of evidence and methodological quality were rated. Meta-analysis was conducted on 14 single case experimental designs using Tau-U, while heterogeneity in the four group designs precluded meta-analysis. Results showed that high-quality research was limited; however, findings were broadly positive for both approaches with neither being judged as clearly superior. Most studies examined impairment-based outcomes without considering participation or quality of life. The application and definition of constraint varied significantly between studies. Both constraint and multimodal therapies are promising for chronic post-stroke aphasia, but there is a need for larger, more rigorously conducted studies. The interpretation of “constraint” also requires clearer reporting.
Why didn't the Nyaya recognize the mind-body problem?

description: Bibliography: p. 155-159
description: Although I contend that the spatiality of the Nyaaya soul goes a long way in explaining why the Nyaaya did not recognize a mind-body interaction problem, I have argued here that there does seem to be an interaction problem nevertheless. I make this claim because what seems to be doing the causal work in mind-body interactions are tropes of the soul. Because these tropes lack any spatial extension, it is hard to see how they can be causally efficacious, particularly if effects need to be spatially contiguous with their causes. In the end, I conclude that the Nyaaya soul, if it is construed along the lines of a classical field as portrayed in modern physical theory, is no more or less problematic, ontologically speaking, than such a field, save for the fact that a mathematical description has not been given for it.

description: The biological requirements for an ecosystem to develop and maintain species diversity are in general unknown. Here we consider a model ecosystem of sessile and mutually excluding organisms competing for space [Mathiesen et al. Phys. Rev. Lett. 107, 188101 (2011)]. The competition is controlled by an interaction network with fixed links chosen by a Bernoulli process. New species are introduced in the system at a predefined rate. In the limit of small introduction rates, the system becomes bistable and can undergo a phase transition from a state of low diversity to high diversity. We suggest that patches of isolated meta-populations formed by the collapse of cyclic relations are essential for the transition to the state of high diversity.

description: Fossilized turtle clutches containing embryos are heretofore undescribed. Here the description of such a specimen from the Upper Cretaceous of Alberta sheds light on the taxonomic identity and paleobiology of the turtle that laid the clutch. Examination of the clutch reveals 33 rigid-shelled, spherical eggs arranged in a layered cluster. Clutch size and the paleoenvironment of the nest site suggest that the fossil clutch belongs to a large, freshwater turtle. Numerous embryonic bones described from virtual reconstructions of computed tomographic data reveal that the embryonic bones are well-ossified. Comparisons with modem turtles indicate the fossil embryos were at a late stage of development, near batching, at the time of death. Morphology of the maxillae, dentary, and plastron suggests affinities with Adocidae, an extinct freshwater turtle clade. Additional lines of evidence, including egg and eggshell morphology, the predicted size of the female, and geographic and stratigraphic location, also suggest that the fossil clutch belongs to adocids.

description: Background: Recombinant human growth hormone (rhGH) reduces visceral adipose tissue (VAT) volume in HIV-infected patients but can worsen glucose homeostasis and lipoatrophy. We aimed to determine if adding rosiglitazone to rhGH would abrogate the adverse effects of rhGH on insulin sensitivity (SI) and subcutaneous adipose tissue (SAT) volume. Methodology/Principal Findings: Randomized, double-blind, placebo-controlled, multicenter trial using a 262 factorial design in which HIV-infected subjects with abdominal obesity and insulin resistance were randomized to rhGH 3 mg daily, rosiglitazone 4 mg twice daily, combination rhGH + rosiglitazone, or double placebo (control) for 12 weeks. The primary endpoint was change in SI by frequently sampled intravenous glucose tolerance test from entry to week 12. Body composition was assessed by whole body magnetic resonance imaging (MRI) and dual Xray absorptiometry (DEXA). Seventy-seven subjects were randomized of whom 72 initiated study drugs. Change in SI from entry to week 12 differed across the 4 arms by 1-way ANCOVA (P = 0.02); by pair-wise comparisons, only rhGH (decreasing SI; P = 0.03) differed significantly from control. Changes from entry to week 12 in fasting glucose and glucose area under the curve on 2- hour oral glucose tolerance test differed across arms (1-way ANCOVA P = 0.004), increasing in the rhGH arm relative to control. VAT decreased significantly in the rhGH arms (217.5% in rhGH/rosiglitazone and 222.7% in rhGH) but not in the rosiglitazone alone (22.5%) or control arms (21.9%). SAT did not change significantly in any arm. DEXA results were consistent with the MRI data. There was no significant rhGH x rosiglitazone interaction for any body composition parameter. Conclusions/Significance: The addition of rosiglitazone abrogated the adverse effects of rhGH on insulin sensitivity and glucose tolerance while not significantly modifying the lowering effect of rhGH on VAT.

description: The battle now raging in the legal academy between the Critical Legal Studies movement (CLS) and its critics has taken a decisive turn. Battles over decisions not to hire or give tenure to scholars associated with CLS have been front-page news in the academic community, and the tone of scholarly discussion has become decidedly negative. Much of the criticism has been aimed at one person often considered a guru to CLS, Roberto Unger. His work has inspired sharply negative commentary both here and abroad, and his most recent work, Politics, has received several scathing reviews.

description: Recently, X-ray imaging dose from computed tomography (CT) or cone beam CT (CBCT) scans has become a serious concern. Patient-specific imaging dose calculation has been proposed for the purpose of dose management. While Monte Carlo (MC) dose calculation can be quite accurate for this purpose, it suffers from low computational efficiency. In response to this problem, we have successfully developed a MC dose calculation package, gCTD, on GPU architecture under the NVIDIA CUDA platform for fast and accurate estimation of the x-ray imaging dose received by a patient during a CT or CBCT scan. Techniques have been developed particularly for the GPU architecture to achieve high computational efficiency. Dose calculations using CBCT scanning geometry in a homogeneous water phantom and a heterogeneous Zubal head phantom have shown good agreement between gCTD and EGSnrc, indicating the accuracy of our code. In terms of improved efficiency, it is found that gCTD attains a speed-up of ~400 times in the homogeneous water phantom and ~76.6 times in the Zubal phantom compared to EGSnrc. As for absolute computation time, imaging dose calculation for the Zubal phantom can be accomplished in ~17 sec with the average relative standard deviation of 0.4%. Though our gCTD code has been developed and tested in the context of CBCT scans, with simple modification of geometry it can be used for assessing imaging dose in CT scans as well.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A model is proposed to demonstrate that classical general relativity can emerge from loop quantum gravity, in a relational description of gravitational field in terms of the coordinates given by matter. Local Dirac observables and coherent states are defined to explore physical content of the model. Expectation values of commutators between the observables for the coherent states recover the four-dimensional diffeomorphism algebra and the large-scale dynamics of the gravitational field relative to the matter coordinates. Both results conform with general relativity up to calculable corrections near singularities.

description: This thesis investigated how contextual cuing varied as a function of stimulus features, awareness of the effect, and participant age. Young and old adults with 20/40 or better near-vision and good self-reported general health completed laboratory-based visual search and recognition tasks. Robust and reliable contextual cuing was found across all samples and conditions. Young and old adults showed equivalent contextual cuing. Varying task difficulty and the contextual information provided did not significantly influence the presence of contextual cuing. Across conditions, participants showed a disruption of contextual cuing once learned context was changed. In most situations this disruption was short-lived. Instructing participants to monitor displays for repetitions of particular displays did not impact the magnitude of the contextual cuing effect. Parametric sensitivity analyses showed that sensitivity for Repeated and Novel displays was at chance levels. Thus, it contextual cuing appears to be a primarily incidental process. Future research could be directed profitably toward the examination of age differences in naturalistic context effects.

description: To discover susceptibility genes of late-onset Alzheimer’s disease (LOAD), we conducted a 3-stage genome-wide association study (GWAS) using three populations: Japanese from the Japanese Genetic Consortium for Alzheimer Disease (JGSCAD), Koreans, and Caucasians from the Alzheimer Disease Genetic Consortium (ADGC). In Stage 1, we evaluated data for 5,877,918 genotyped and imputed SNPs in Japanese cases (n = 1,008) and controls (n = 1,016). Genome-wide significance was observed with 12 SNPs in the APOE region. Seven SNPs from other distinct regions with p-values ,261025 were genotyped in a second Japanese sample (885 cases, 985 controls), and evidence of association was confirmed for one SORL1 SNP (rs3781834, P=7.3361027 in the combined sample). Subsequent analysis combining results for several SORL1 SNPs in the Japanese, Korean (339 cases, 1,129 controls) and Caucasians (11,840 AD cases, 10,931 controls) revealed genome wide significance with rs11218343 (P=1.7761029) and rs3781834 (P=1.0461028). SNPs in previously established AD loci in Caucasians showed strong evidence of association in Japanese including rs3851179 near PICALM (P=1.7161025) and rs744373 near BIN1 (P = 1.3961024). The associated allele for each of these SNPs was the same as in Caucasians. These data demonstrate for the first time genome-wide significance of LOAD with SORL1 and confirm the role of other known loci for LOAD in Japanese. Our study highlights the importance of examining associations in multiple ethnic populations.
Detonation stability in the chain-branching regime assuming a small initiation rate

description: Bibliography: p. 97-107
description: Hydrogen chemistry is characterized by a specific chain-branching chemical kinetic mech­anism leading to an S-shaped chain-branching explosion diagram, and characterized by an induction length much longer than the main reaction zone controlled by chain-branching. A simple three step kinetic scheme helps understanding how chain-branching works, and how it may affect detonation stability. A stability analysis of the steady, one dimensional Zel'dovich-von Neumann-Doering (ZND) detonation wave is performed for the case where the post-shock state lies inside the chain-branching explosion region, assum­ing that the initiation rate is small, which is especially accurate in the case of hydrogen. Instability of the planar wave is thought to be related to the cellular structure adopted by 11 early all detonation waves observed in experiments. Linear stability entails identifying whether the growth rate of a small perturbation is positive. The perturbation problem depends upon the steady, planar ZND reference solution, the stability of which is being investigated. Thus the coefficients in the linear perturbation problem depend upon the longitudinal coordinate, but not upon time nor the transverse coordinate. Hence the solution can be expressed in Fourier space in time and in relation to the transverse co­ordinate. Because the ZND solution is obtained numerically, the perturbation problem also requires a numerical solution. In relation to previous stability analysis, the main challenge in the current study was in formulating the proper boundary conditions, under the assumption of slow initiation rate. Results consist of the growth rates and frequencies of the dominant eigenmodes. Although the formulation handles transverse modes with no additional difficulty, results shown only consider longitudinal modes.

description: Most agricultural water quality models are based on umped parameterizations of spatial process. The AgSimGIS water quality tool has been developed to predict space-time planning scenarios across spatially variable agricultural landscapes. The tool runs under the ArcGIS 8.3 environment, and consists of a multi-functional system for simulation modeling and spatial data storage, analysis, and display. AgSimGIS offers a spatial framework for integrating a complex, agricultural system water quality a model (modified USDA-ARS RZWWQM) with interaction between simulated land areas via overland runoff and runon. AgSimGIS also provides the increased interface sophistication necessary for distributed hydrologic modeling. AgSimGIS development history, including an overview of the major GIS and simulation modeling components, will be presented.

description: We present discovery limits for heavy quarks in the Bestest Little Higgs model via pair production at the LHC running at $\sqrt{s} = 7 \mathrm{TeV}$. We study pair produced heavy top-like quarks decaying to $b\bar{b}W^+W^-$ and $t\bar{t}ZZ$ final states and singly produced heavy top-like quarks via t-channel $W$ exchange. These results are compared to currently available limits on heavy top-like quark cross sections from CMS (with 1.14 fb$^{-1}$ integrated luminosity) for two scenarios of Yukawa couplings. We find that the CMS data limits the mass of the lightest top partner to larger than 413 GeV in the first scenario, where the two lightest top-partners have a small mass splitting, and 364 GeV in the second scenario, where the mass splitting between the two lightest top-partners is larger.

description: Hepatitis C virus (HCV) and human pegivirus (HPgVorGBvirusC) are globally distributed and infect 2 to 5% of the human population. The lack of tractable-animal models for these viruses, in particular for HCV, has hampered the study of in- fection, transmission, virulence, immunity, and pathogenesis. To address this challenge, we searched for homologous viruses in small mammals, including wild rodents. Here we report the discovery of several new hepaciviruses (HCV-like viruses) and pegiviruses (GB virus-like viruses) that infect wild rodents. Complete genome sequences were acquired for a rodent hepacivirus (RHV) found in Peromyscus maniculatus and a rodent pegivirus (RPgV) found in Neotoma albigula. Unique genomic features and phylogenetic analyses confirmed that these RHV and RPgV variants represent several novel virus species in the Hepacivirus and Pegivirus genera within the family Flaviviridae. The genetic diversity of the rodent hepaciviruses exceeded that observed for hepaciviruses infecting either humans or non-primates, leading to new insights into the origin, evolution, and host range of hepaciviruses. The presence of genes, encoded proteins, and translation elements homologous to those found in human hepaciviruses and pegiviruses suggests the potential for the development of new animal systems with which to model HCV pathogenesis, vaccine design, and treatment.

We show that faceting occurs in regions where the vesicle wall is softer, such as areas of reduced wall thicknesses or concentrated in crystalline defects. The elastic heterogeneities are modeled as a second component with reduced elastic parameters. Using simulated annealing Monte Carlo simulations we obtain the vesicle shape by optimizing the distributions of facets and boundaries. Our model allows us to reduce the effects of the residual stress generated by crystalline defects, and reveals a robust faceting mechanism into polyhedra other than the icosahedron.

Modelling channel morphodynamics associated with large wood in an intermediate-sized stream
Creators: name: Davidson, Sarah
Publisher: name: University of British Columbia
Year: 2011

description: The primary objective of this research is to investigate the relationship between wood load and reach-scale morphodynamics using a model system. Previous re- search has shown that large wood significantly impacts channel dynamics, espe- cially in small and intermediate sized forested streams where wood pieces are similar in length to channel width. Five experiments, each comprised of several five hour runs, were conducted using a stream table with wood loads scaled to 0 m³/m², 0.011 m³/m², 0.016 m³/m², 0.022 m³/m², and 0.028 m³/m². The addition of large wood significantly increased the flow resistance and decreased the reach-averaged velocity in all experiments. These hydraulic changes were associated with decreased sediment transport and increased sediment storage within the reach. Over time, increases in bed and water surface slope compensated for the loss of potential energy to flow resistance and enabled the system to reach a new steady state. The heterogeneity in the spatial distribution of the hydraulic changes – with flow velocity and shear stress decreasing upstream of obstructions and increasing downstream of log steps – increased the facies complexity and pool frequency in the reach at the new steady state, and thereby increased habitat complexity. These results show that wood load is a primary control on channel morphodynamics and the availability of aquatic habitat in intermediate sized streams.

description: Using the Hartree-Fock plus random-phase-approximation (HF+RPA), we study the impurity effect of $Λ$ hyperon on the collective vibrational excitations of double-$Λ$ hypernuclei. To this end, we employ a Skyrme-type $ΛN$ and $ΛΛ$ interactions for the HF calculations, and the residual interactions for RPA derived with the same interactions. We find that inclusion of two $Λ$ hyperons in $^{16}$O shifts the energy of the collective states towards higher energies. In particular, the energy of the giant monopole resonance of $^{\,\,18}_{ΛΛ}$O, as well as that of $^{210}_{ΛΛ}$Pb, becomes larger. This implies that the effective incompressibility modulus increases due to the impurity effect of $Λ$ particle, if the $β$-stability condition is not imposed.

Entanglement spectrum of the Heisenberg XXZ chain near the ferromagnetic point

description: We study the entanglement spectrum (ES) of a finite XXZ spin 1/2 chain in the limit Δ-> -1^+ for both open and periodic boundary conditions. At Δ=-1 (ferromagnetic point) the model is equivalent to the Heisenberg ferromagnet and its degenerate ground state manifold is the SU(2) multiplet with maximal total spin. Any state in this so-called "symmetric sector" is an equal weight superposition of all possible spin configurations. In the gapless phase at Δ>-1 this property is progressively lost as one moves away from the Δ=-1 point. We investigate how the ES obtained from the states in this manifold reflects this change, using exact diagonalization and Bethe ansatz calculations. We find that in the limit Δ->-1^+ most of the ES levels show divergent behavior. Moreover, while at Δ=-1 the ES contains no information about the boundaries, for Δ>-1 it depends dramatically on the choice of boundary conditions. For both open and periodic boundary conditions the ES exhibits an elegant multiplicity structure for which we conjecture a combinatorial formula. We also study the entanglement eigenfunctions, i.e. the eigenfunctions of the reduced density matrix. We find that the eigenfunctions corresponding to the non diverging levels mimic the behavior of the state wavefunction, whereas the others show intriguing polynomial structures. Finally we analyze the distribution of the ES levels as the system is detuned away from Δ=-1.

description: Marine reserves are an effective tool for protecting biodiversity locally, with potential economic benefits including enhancement of local fisheries, increased tourism, and maintenance of ecosystem services. However, fishing communities often fear short-term income losses associated with closures, and thus may oppose marine reserves. Here we review empirical data and develop bioeconomic models to show that the value of marine reserves (enhanced adjacent fishing + tourism) may often exceed the pre-reserve value, and that economic benefits can offset the costs in as little as five years. These results suggest the need for a new business model for creating and managing reserves, which could pay for themselves and turn a profit for stakeholder groups. Our model could be expanded to include ecosystem services and other benefits, and it provides a general framework to estimate costs and benefits of reserves and to develop such business models.

description: Loess formation generally involves the four main stages of production, deflation, transportation, and deposition of loess particles. Traditionally, loesses are classified as glacial, desert, or other types based only on source area characteristics without taking into account provenance and transportation. Research on loess genesis is often local with only a few attempts at systematically overviewing worldwide loess distribution. Both the local and few global studies lack information on the variability in loess thickness, continuity, and areal extent. This review integrates a large body of information on loess source areas and transportation pathways and the existence of desert transition zones. Three modes of loess genesis, (1) continental glacier provenance-river transport, (2) mountain provenance-river transport, and (3) mountain provenance-river transport-desert transition, were identified. Global distribution maps of provenance and transport pathways of major loess areas and their different genesis modes were meticulously prepared. Maps showing the spatial distribution, thickness, and continuity of loess deposits were also composed and the sizes of loess-covered areas of each continent were re-estimated. The main features related to the distribution of the loess deposits on each continent are summarized for different regions or as a whole depending on the coverage of the source maps and references.

description: There are two main approaches to non-equlibrium statistical mechanics: one using stochastic processes and the other using dynamical systems. To model the dynamics during inflation one usually adopts a stochastic description, which is known to suffer from serious conceptual problems. To overcome the problems and/or to gain more insight, we develop a dynamical systems approach. A key assumption that goes into analysis is the chaotic hypothesis, which is a natural generalization of the ergodic hypothesis to non-Hamiltonian systems. The unfamiliar feature for gravitational systems is that the local phase space trajectories can either reproduce or escape due to the presence of cosmological and black hole horizons. We argue that the effect of horizons can be studied using dynamical systems and apply the so-called thermodynamic formalism to derive the equilibrium (or Sinai-Ruelle-Bowen) measure given by a variational principle. We show that the only physical measure is not the Liouville measure (i.e. no entropy problem), but the equilibrium measure (i.e. no measure problem) defined over local trajectories (i.e. no problem of observables) and supported on only infinite trajectories (i.e. no problem of initial conditions). Phenomenological aspects of the fluctuation theorem are discussed.
