Conductance of electrolytes in 1-propanol solutions from −40 to 25°C

Conductance data for solutions of LiCl, NaBr, NaI, KI, KSCN, RbI, Et4NI, Pr4NI, Bu4NI, Bu4NClO4, n-Am4NI, i-Am4NI, n-Hept4NI, Me2Bu2NI, MeBu3NI, EtBu3NI, i-Am3BuNI, and i-Am3BuNBPh4 in 1-propanol at –40, –30, –20, –10, 0, 10, and 25°C are communicated and discussed. Evaluation of the data is performed on the basis of a conductance equation that includes a term in c3/2. Single ion conductances at 25 and 10°C are determined with the help of transference numbers t o + (KSCN/PrOH); the data are compared to data estimated by other methods. Ion-pair association constants and their temperature dependence are discussed in terms of contact and solvent separated ion pairs, and the role of non-coulombic forces is shown with the help of an appropriate splitting of the Gibbs energy of ion-pair formation

Identifying Social and Cultural Barriers to Food Security in Nicaragua

IMPACT. 1: This effort will involve local researchers and community members in a much-needed food security and health study in León, Nicaragua, and in outreach efforts that provide evidencebased feedback to the local communities about these health issues. -- 2. The immediate outcome of the project will be the identification of barriers to food security and child health in poor communities in León, Nicaragua. In the long-term, this project will yield invaluable future opportunities for Ohio State students and faculty to engage with local communities in research, learning and service in an international setting, where food insecurity and child malnutrition present serious threats to individuals' well-being.OSU PARTNERS: Department of Anthropology; Department of Sociology; College of Arts and SciencesCOMMUNITY PARTNERS: Center for Demographic; and Health Research (León, Nicaragua)PRIMARY CONTACT: Barbara Piperata ([email protected]); Kammi Schmeer ([email protected])With approximately 1 billion people world-wide suffering from lack of adequate access to food, food insecurity and maternal-child malnutrition remain critical health issues in poor communities around the world. This project aims to address this pressing need in poor communities in Nicaragua (the 2nd poorest country in the Western hemisphere) through an "outreach through research" approach

Evaluating a rugby sport intervention programme for young offenders

Purpose: Interventions intended to aid offender re-entry, rehabilitation and desistence based around specific sports and championed by sporting institutions have been introduced in custodial settings. Though research evaluating these is positive (Meek, 2012), conclusions are often hampered by the absence of control groups in such work. This study will evaluate the Saracens “Get Onside” rugby based intervention at HMPYOI Feltham, while employing a non-randomised control group. Design and Methodology: In total 24 young offenders took part. Those in the treatment condition experienced a ten week course which included a range of activities leading to accredited awards, exercises in functional skills in literacy/numeracy and 72 hours of rugby sessions. Those in the control condition were matched on key static factors, crime attitudes and aggression. Self-reported measures of pro-crime attitudes, aggression, self-esteem, and impulsivity were taken once before the start, once during, and at the end of the course for both groups. Findings: As predicted, self-reported scores measuring attitudes towards aggression and crime did differ significantly across groups, with those experiencing the intervention showing more positive values by the end of treatment compared with others. However, measures of impulsiveness and self-esteem showed no change. Limitations: Revisions are suggested in respect of both the self-esteem and impulsivity measures, and future work needs better control over the match between treatment and comparison groups. Originality/Value: This paper shows that concerns over the potentially iatrogenic effects of contact sport interventions may be misplaced, and the benefits of sporting interventions are replicated in a between groups design.Peer reviewe

Stickstoffflüsse im System Boden-Pflanze nach einer Grünlanderneuerung mit eingeschobener Ackerzwischennutzung

An Experiment to examine the nitrogen fluxes after ploughing up and resowing grassland was conducted on the organic experimental station “Lindhof” in northern Germany. The trial was implemented on a uniform grassland site (since 1993) focussing on the factors grassland resowing, fertilisation with organic cattle slurry (0/230 kg ha-1) and year of renovation (2005, 2006, 2008). The factor grassland resowing further involved the following treatments: 1. undisturbed control, 2. ploughing up and resowing grassland in late summer, 3. ploughing up of grassland in autumn followed by winter wheat and grassland resowing the year after, 4. ploughing up of grassland in spring followed by spring wheat and grassland resowing the year after. Ploughing up in autumn induced increased nitrate leaching. Inserted wheat cultivation led to higher leaching in the second winter. N-yields of the newly sown grassland did not exceed those of the undisturbed control due to a low content of white clover in newly established grassland

Klimagasemission im Futterbau: Vergleich von leguminosenbasierten und intensiv stickstoffgedüngten Grünlandbeständen

Aim of the presented study was the comparison of the specific emissions of CO2 equivalents of a legume based and a mineral N fertilised grassland considering the N2O emissions caused by N fertilisation and soil compaction. The field trial was set up on the experimental station “Hohenschulen” in northern Germany with the factors soil compaction, N fertilisation and experimental year. The N2O emissions were affected by an interaction of soil compaction and N fertilisation, especially under moist spring conditions. The specific CO2-equivalent emission per unit energy yield was 67 % higher for the mineral N-fertilised grassland compared to the legume based grassland

Period change of Superhumps in the WZ Sge-Type Dwarf Nova, HV Virginis

After 10 years of quiescence, HV Vir underwent a superoutburst in January 2002. We report time-series observations clearly revealing the period change of ordinary superhumps during the superoutburst. We derived a mean superhump period of 0.058260 d and a positive period derivative of $7 \times 10^{-5}$. These results are in good agreement with the value obtained from the 1992 superoutburst. We also detected early superhumps, which were not clearly recognized in the past outburst, and a possible rebrightening. Both of them are the common characteristics of WZ Sge-type stars.Comment: 9 pages, 8 figures. Accepted for publication in PAS

Discovery of a New Deeply Eclipsing SU UMa-Type Dwarf Nova, IY UMa (= TmzV85)

We discovered a new deeply eclipsing SU UMa-type dwarf nova, IY UMa, which experienced a superoutburst in 2000 January. Our monitoring revealed two distinct outbursts, which suggest a superoutburst interval of ~800 d, or its half, and an outburst amplitude of 5.4 mag. From time-series photometry during the superoutburst, we determined a superhump and orbital period of 0.07588 d and 0.0739132 d, respectively.Comment: 5 pages, 3 figures, accepted by PASJ lette

Inspiration vs. Appropriation: Representation of Indigenous Cultures in Western Dance Companies

In modern, Westernized society, we are often fascinated by cultures that differ from our own. The well-meaning interest in other cultures, especially the cultures of indigenous tribes, can become problematic when people unknowingly treat these very real cultures and people as fictional entities. Our words and actions can perpetuate stereotypes harmful to these minority groups, contributing to an idea of “otherness,” the idea that these people are separate from us. Artists have a high degree of responsibility when using other cultures as inspiration for their work. A long, brutal history of genocide, racism, and theft of land and identity makes dealing with indigenous tribes a sensitive and complex matter. Concurrently, it is important their cultures be shared and appreciated. This paper will explore how dance choreographers have successfully navigated the terrain between inspiration and appropriation, focusing specifically on Jiří Kylián, director of the Nederlands Dans Theater, use of the Aboriginal cultures for his ballet Stamping Ground, as well as the Limón Dance Company’s piece based on Native American tribes. Their works will be compared to pieces performed by the American Indian Dance Theatre. This paper will also discuss cultural equity, an ideal championed by Alan Lomax, an American ethnomusicologist

Dance and the New Deal

Dance, like all art, acts as an important factor in social change. Dancers and choreographers have frequently sought to challenge the status quo, whether by removing women’s corsets and incorporating natural movements into pieces as Isadora Duncan did, or by creating dances with political subject matter, like in Kurt Jooss’s The Green Table. Despite the clear importance of the arts, securing funding has always been and continues to be an uphill battle. The period of the Great Depression in the 1930s saw huge growth in many artistic spheres through the implementation of Franklin Delano Roosevelt’s New Deal. The art projects and programs of the New Deal acted as a harbinger of the National Endowment for the Arts and laid the foundation for dance to be recognized as its own genre separate from theatre. This paper will explore the history of dance and dance funding, beginning with and focusing on the Federal Theatre and Federal Dance Projects. It will go on to discuss the National Endowment for the Arts and engage with larger ideas about artistic funding
