Towards typologies of virtual maltreatment: Sport, digital cultures and dark leisure.

A changing technological context, specifically that of the growth of social media, is transforming aspects of leisure behaviour, especially in terms of negative interactions between followers of sport and athletes. There is a growing body of research into the maltreatment of adult athletes, exploring issues such as abusive acts or behaviours against the individual, including acts of physical and/or psychological violence to the person. Existing research however, focuses upon face-to-face behaviours, and to date the nature of abuse in online spaces has been overlooked. It is becoming ever more apparent that virtual environments create optimal climates for abuse to occur due to the ability for individuals to communicate in an instantaneous, uncontrolled and often anonymous manner in virtual worlds. Using a netnographic approach, an analysis of a popular social media platform (Twitter) was conducted to examine the types of abuse present in online environments. This paper presents a conceptual typology, identifying four broad types of abuse in this setting; physical, sexual, emotional and discriminatory; examples of each form are presented. Findings highlight how online environments can pose a significant risk to individual emotional and psychological safety

Assessing depleted uranium (DU) contamination of soil, plants and earthworms at UK weapons testing sites

Depleted uranium (DU) weapons testing programmes have been conducted at two locations within the UK. An investigation was therefore carried out to assess the extent of any environmental contamination arising from these test programmes using both alpha spectrometry and mass spectrometry techniques. Uranium isotopic signatures indicative of DU contamination were observed in soil, plant and earthworm samples collected in the immediate vicinity of test firing points and targets, but contamination was found to be localised to these areas. The paper demonstrates the superiority of the 235U:238U ratio over the 234U:238U ratio for identifying and quantifying DU contamination in environmental samples and also describes the respective circumstances under which alpha spectrometry or mass spectrometry may be the more appropriate analytical tool

The Effects of a Powerful Military on Compliance with International Human Rights Tribunals

Are states with a powerful military force less likely to comply with European Court of Human Rights (ECtHR) and Inter-American Court of Human Rights (IACtHR) judgements and rulings? The main foundation of the paper is built upon Hillebrecht’s definition of compliance and why a particular state complies with the rulings of the ECtHR and IACtHR. Domestic institutions are the driving force behind a state’s willingness to comply because of the significant lack of enforcing power behind these international institutions. The goal of the paper is to expand upon what Hillebrecht started by looking past the basic domestic institutions like executive branch power, an independent judiciary, and a prosperous civil society and, instead, look at the military power of states. By focusing on the military might of states, I argue that this coincides with the Realist theory approach to International Relations (IR) where states are in a constant power struggle in international relations. I also draw on the rational functionalist approach to IR. I utilize both Hillebrecht’s Compliance with Human Rights Tribunals (CHRT) dataset and the National Material Capabilities v5.0 (NMC) dataset to gather state compliance under the two tribunals as well as a strong definition for what a powerful military is. The implications of this study could be the expansion of the IR literature as a whole by adding a completely different approach to studying noncompliance and the power of states while also providing possible policy implications for noncompliance

Nitrous oxide emissions from a peatbog after 13 years of experimental nitrogen deposition

Nitrogen deposition was experimentally increased on a Scottish peatbog over a period of 13 years (2002–2015). Nitrogen was applied in three forms, NH3 gas, NH4Cl solution, and NaNO3 solution, at rates ranging from 8 (ambient) to 64 kg N ha−1 yr−1, and higher near the NH3 fumigation source. An automated system was used to apply the nitrogen, such that the deposition was realistic in terms of rates and high frequency of deposition events. We measured the response of nitrous oxide (N2O) flux to the increased nitrogen input. Prior expectations, based on the IPCC default emission factor, were that 1 % of the added nitrogen would be emitted as N2O. In the plots treated with NH4+ and NO3− solution, no response was seen, and there was a tendency for N2O fluxes to be reduced by additional nitrogen, though this was not significant. Areas subjected to high NH3 emitted more N2O than expected, up to 8.5 % of the added nitrogen. Differences in the response are related to the impact of the nitrogen treatments on the vegetation. In the NH4+ and NO3− treatments, all the additional nitrogen is effectively immobilised in the vegetation and top 10 cm of peat. In the NH3 treatment, much of the vegetation was killed off by high doses of NH3, and the nitrogen was presumably more available to denitrifying bacteria. The design of the wet and dry experimental treatments meant that they differed in statistical power, and we are less likely to detect an effect of the NH4+ and NO3− treatments, though they avoid issues of pseudo-replication

A Study of the Diverse T Dwarf Population Revealed by WISE

We report the discovery of 87 new T dwarfs uncovered with the Wide-field Infrared Survey Explorer (WISE) and three brown dwarfs with extremely red near-infrared colors that exhibit characteristics of both L and T dwarfs. Two of the new T dwarfs are likely binaries with L7+/-1 primaries and mid-type T secondaries. In addition, our follow-up program has confirmed 10 previously identified T dwarfs and four photometrically-selected L and T dwarf candidates in the literature. This sample, along with the previous WISE discoveries, triples the number of known brown dwarfs with spectral types later than T5. Using the WISE All-Sky Source Catalog we present updated color-color and color-type diagrams for all the WISE-discovered T and Y dwarfs. Near-infrared spectra of the new discoveries are presented, along with spectral classifications. To accommodate later T dwarfs we have modified the integrated flux method of determining spectral indices to instead use the median flux. Furthermore, a newly defined J-narrow index differentiates the early-type Y dwarfs from late-type T dwarfs based on the J-band continuum slope. The K/J indices for this expanded sample show that 32% of late-type T dwarfs have suppressed K-band flux and are blue relative to the spectral standards, while only 11% are redder than the standards. Comparison of the Y/J and K/J index to models suggests diverse atmospheric conditions and supports the possible re-emergence of clouds after the L/T transition. We also discuss peculiar brown dwarfs and candidates that were found not to be substellar, including two Young Stellar Objects and two Active Galactic Nuclei. The coolest WISE-discovered brown dwarfs are the closest of their type and will remain the only sample of their kind for many years to come.Comment: Accepted to ApJS on 15 January 2013; 99 pages in preprint format, 30 figures, 12 table

The AllWISE Motion Survey, Part 2

We use the AllWISE Data Release to continue our search for WISE-detected motions. In this paper, we publish another 27,846 motion objects, bringing the total number to 48,000 when objects found during our original AllWISE motion survey are included. We use this list, along with the lists of confirmed WISE-based motion objects from the recent papers by Luhman and by Schneider et al. and candidate motion objects from the recent paper by Gagne et al. to search for widely separated, common-proper-motion systems. We identify 1,039 such candidate systems. All 48,000 objects are further analyzed using color-color and color-mag plots to provide possible characterizations prior to spectroscopic follow-up. We present spectra of 172 of these, supplemented with new spectra of 23 comparison objects from the literature, and provide classifications and physical interpretations of interesting sources. Highlights include: (1) the identification of three G/K dwarfs that can be used as standard candles to study clumpiness and grain size in nearby molecular clouds because these objects are currently moving behind the clouds, (2) the confirmation/discovery of several M, L, and T dwarfs and one white dwarf whose spectrophotometric distance estimates place them 5-20 pc from the Sun, (3) the suggestion that the Na 'D' line be used as a diagnostic tool for interpreting and classifying metal-poor late-M and L dwarfs, (4) the recognition of a triple system including a carbon dwarf and late-M subdwarf, for which model fits of the late-M subdwarf (giving [Fe/H] ~ -1.0) provide a measured metallicity for the carbon star, and (5) a possible 24-pc-distant K5 dwarf + peculiar red L5 system with an apparent physical separation of 0.1 pc.Comment: 62 pages with 80 figures, accepted for publication in The Astrophysical Journal Supplement Series, 23 Mar 2016; second version fixes a few small typos and corrects the footnotes for Table

Improving Student Success: Arkansas State’s Partnership With Credo and Regional High Schools

In this “out of the box” session, two librarians from Arkansas State University (A-State) and Credo’s chief content officer discussed their innovative collaboration in which A-State and Credo are working together to bring information literacy resources and instruction to local high schools in support of college readiness. The session covered several issues, including how the library engaged and garnered administrative support, the challenges in establishing meaningful partnerships with local high schools, and developing and tracking the right metrics to validate progress. Topics of discussion included ways in which the library is working to do more to enhance its strategic importance relative to administration goals; an overview of the established project goals and how success will be tracked in areas, including college preparedness, retention, graduation rates, grade point average (GPA), and recruiting; and why this matters to the A-State Library. Participants were encouraged to share their experiences and provide feedback

A Silylation Based Kinetic Resolution of Secondary Alcohols And The Synthesis And Structural Characterization of Pyridyl-oxazolidine Compounds

Described herein is the first enantioselective silylation based kinetic resolution of monofunctional secondary alcohols to achieve useful levels of enantioselectivity. Using commercially available reagents, the reaction conditions were optimized and found to successfully resolve several secondary alcohols with high enantioselectivity. It was discovered that the nucleophilic isothiourea compound (-)-tetramisole, with Ph3SiCl as the silyl source, gave superior results to other nucleophilic catalysts and was capable of performing the kinetic resolution in as little as 45 minutes using mild reaction conditions. The structural and electronic characteristics of successful and less successful substrates are also discussed. Chapter three discusses mechanistic investigations and the characterization of the reactive silylating compounds for the enantioselective silylation of monofunctional secondary alcohols with (-)-tetramisole and other nucleophiles. Solid state and solution based 1H and 29Si NMR techniques were utilized as well as a modified 1H-29Si gHSQC NMR technique. Evidence to support a tetravalent silicon intermediate between (-)-tetramisole and Ph3SiCl is presented. Then, circular dichroism studies were performed on some chiral silyl ethers to see if a nearby chiral center can cause the aryl groups to favor a single helical conformation. Chapter four presents the synthesis and structural characteristics of chiral 2-pyridyloxazolidine and 2,6-pyridylbisoxazolidine compounds. These compounds were found to be viable ligands in the formation of metal complexes. Their ability to behave as colorimetric sensors for chiral monofunctional alcohols and amines is also reported. In addition, their use as an organocatalyst for the kinetic resolution of secondary alcohols by enantioselective silylation is also discussed. ourea compound (-)-tetramisole, with Ph3SiCl as the silyl source, gave superior results to other nucleophilic catalysts and was capable of performing the kinetic resolution in as little as 45 minutes using mild reaction conditions. The structural and electronic characteristics of successful and less successful substrates are also discussed

Ensembl regulation resources

New experimental techniques in epigenomics allow researchers to assay a diversity of highly dynamic features such as histone marks, DNA modifications or chromatin structure. The study of their fluctuations should provide insights into gene expression regulation, cell differentiation and disease. The Ensembl project collects and maintains the Ensembl regulation data resources on epigenetic marks, transcription factor binding and DNA methylation for human and mouse, as well as microarray probe mappings and annotations for a variety of chordate genomes. From this data, we produce a functional annotation of the regulatory elements along the human and mouse genomes with plans to expand to other species as data becomes available. Starting from well-studied cell lines, we will progressively expand our library of measurements to a greater variety of samples. Ensembl's regulation resources provide a central and easy-to-query repository for reference epigenomes. As with all Ensembl data, it is freely available at http://www.ensembl.org, from the Perl and REST APIs and from the public Ensembl MySQL database server at ensembldb.ensembl.org.Database URL: http://www.ensembl.org.Wellcome Trust grant: (WT098051); National Human Genome Research Institute grants: (U41HG007234, 1U01 HG004695); Biotechnology and Biological Sciences Research Council grant: (BB/L024225/1); European Molecular Biology Laboratory; European Union’s Seventh Framework Programme; European Research Council

Discoveries from a Near-infrared Proper Motion Survey using Multi-epoch 2MASS Data

We have conducted a 4030-square-deg near-infrared proper motion survey using multi-epoch data from the Two Micron All-Sky Survey (2MASS). We find 2778 proper motion candidates, 647 of which are not listed in SIMBAD. After comparison to DSS images, we find that 107 of our proper motion candidates lack counterparts at B-, R-, and I-bands and are thus 2MASS-only detections. We present results of spectroscopic follow-up of 188 targets that include the infrared-only sources along with selected optical-counterpart sources with faint reduced proper motions or interesting colors. We also establish a set of near-infrared spectroscopic standards with which to anchor near-infrared classifications for our objects. Among the discoveries are six young field brown dwarfs, five "red L" dwarfs, three L-type subdwarfs, twelve M-type subdwarfs, eight "blue L" dwarfs, and several T dwarfs. We further refine the definitions of these exotic classes to aid future identification of similar objects. We examine their kinematics and find that both the "blue L" and "red L" dwarfs appear to be drawn from a relatively old population. This survey provides a glimpse of the kinds of research that will be possible through time-domain infrared projects such as the UKIDSS Large Area Survey, various VISTA surveys, and WISE, and also through z- or y-band enabled, multi-epoch surveys such as Pan-STARRS and LSST.Comment: To appear in the September 2010 issue of The Astrophysical Journal, Supplement Serie
