    PERCUSSION INSTRUCTION IN BEGINNING BAND FOR PROGRAMS WITH A SINGLE TEACHER An Abstract of the Thesis by Micah A. Martin The primary purpose of this study was to find the best methods for developing students into total percussionists in beginning band programs with only one band director on staff. A total percussionist is defined as one who is capable of playing keyboard percussion, snare drum, timpani, and the accessory instruments. The study consists of a survey to assess individual approaches to percussion instruction in beginning band. A questionnaire was developed using Google Forms and a link was emailed to band directors in Kansas, Missouri, and Arkansas. A link was also posted on the Facebook pages of the Southwest Missouri Music Educators Association and the Missouri Music Educators Association. Most of the respondents start percussion along with the other band students on both snare drum and keyboard percussion in the sixth grade. About four-fifths of them do not meet with percussionists for rehearsals or lessons outside of class. Around two-thirds indicated that their percussionists do not take lessons outside of school. Over half of them are able to meet class daily. Over half meet at least ninety minutes per week. However, many of the directors believe that they need more time for beginning band, and especially percussion

    Compost Tea Quality and Fertility

    The water extract of compost termed “compost tea” retains all the beneficial soluble bioactive components, making it a potent source of plant stimulatory and defensive compounds. The exact nature and extent of these features are, however, modified by composting system, feedstock quality, tea preparation and resultant use and management, including application dynamics of the compost tea. Compost teas contain a significant quantity of total nutrients with the majority being primary macronutrients. Secondary and micronutrient concentrations are more variable, but contents are generally insufficient to satisfy crop requirements. Noting this, compost tea use in agriculture and horticulture supports crop nutrition directly and indirectly. Improvements in soil quality have been widely reported for a range of soils and compost teas. A key feature of compost tea-amended soils is the increase in soil organic matter and microbial diversity and its associated benefits. Research on appropriates rates for field and container use show large variability associated with edapho-climatic factors and crop species. However, foliar application seems best suited to maximising the dual nutrition and phytopathogenic effects of compost tea. Regardless of the purpose of compost tea use, its positive effects on crop growth and soil fertility, whilst controlling pest and disease, make it a contemporary sustainable tool aligned to organic agriculture

    Voting on Cyclic Orders, Group Theory, and Ballots

    A cyclic order may be thought of informally as a way to seat people around a table, perhaps for a game of chance or for dinner. Given a set of agents such as {A,B,C}\{A,B,C\}, we can formalize this by defining a cyclic order as a permutation or linear order on this finite set, under the equivalence relation where A≻B≻CA\succ B\succ C is identified with both B≻C≻AB\succ C\succ A and C≻A≻BC\succ A\succ B. As with other collections of sets with some structure, we might want to aggregate preferences of a (possibly different) set of voters on the set of possible ways to choose a cyclic order. However, given the combinatorial explosion of the number of full rankings of cyclic orders, one may not wish to use the usual voting machinery. This raises the question of what sort of ballots may be appropriate; a single cyclic order, a set of them, or some other ballot type? Further, there is a natural action of the group of permutations on the set of agents. A reasonable requirement for a choice procedure would be to respect this symmetry (the equivalent of neutrality in normal voting theory). In this paper we will exploit the representation theory of the symmetric group to analyze several natural types of ballots for voting on cyclic orders, and points-based procedures using such ballots. We provide a full characterization of such procedures for two quite different ballot types for n=4n=4, along with the most important observations for n=5n=5.Comment: 29 pages, to be published in conference proceedings from AMS Special Session on The Mathematics of Decisions, Elections and Games, 202

    WikiDo

    Not formally publishedThe Internet has allowed collaboration on an unprecedented scale. Wikipedia, Luis Von Ahn’s ESP game, and reCAPTCHA have proven that tasks typically performed by expensive in-house or outsourced teams can instead be delegated to the mass of Internet computer users. These success stories show the opportunity for crowdsourcing other tasks, such as allowing computer users to help each other answer questions like “How do I make my computer do X?”. Such a system would reduce IT cost, user frustration, and machine downtime. The current approach to crowd-sourcing IT tasks, however, only allows users to collaborate on generating text. Anyone who goes through the process of searching help wikis and user forums hoping to find a solution for some computer problem knows the inefficacy and the frustration accompanying such a process. Text is ambiguous and often incomplete, particularly when written by non-experts. This paper presents WikiDo, a system that enables the mass of non-expert users to help each other answer how-to computer questions by actually performing the task rather than documenting its solution.National Science Foundation (U.S.) (grant IIS-0835652

    Learn the Terms: A Visual Glossary, 2016 Edition

    Get PDF
    Understanding a discipline requires a fundamental understanding of its terminology. The terminology of information literacy, used by librarians and professors, comprises a language integrated within all disciplines. Critical to academic success, it’s often assumed to be widely understood by students. The students of Graphic Design V, fall 2016, created a visual glossary to help students learn this critical terminology. This bold, eye-catching informational campaign, produced and disseminated in and outside of the Library, promotes learning through innovative designs created by students for students. The materials, introduced in a 2017 ACRL presentation, Warning! This Program Contains Graphic Content: Facilitating Understanding of Library Terms through Visual Rhetoric, include bookmarks, tabletoppers, and digital images.https://scholarworks.gvsu.edu/oer_teaching/1001/thumbnail.jp

    Which medications benefit patients with diastolic heart failure?

    Angiotensin-converting enzyme inhibitors (ACEIs), propranolol, statins, furosemide, and some angiotensin receptor blockers (ARBs) benefit patients. Medications that reduce mortality in diastolic heart failure include ACEIs (strength of recommendation [SOR]: C, 1 prospective cohort trial with matched controls), propranolol (SOR: B, 1 randomized controlled trial [RCT]), and statins (SOR: C, 1 prospective cohort trial). Furosemide improves symptoms of heart failure and quality of life (SOR: C, 1 RCT, using cohort data). ARBs show mixed results: candesartan decreases hospital admissions (SOR: B, 1 large RCT); losartan improves exercise duration and quality of life (SOR: B, 2 small RCTs); irbesartan doesn't improve heart failure symptoms or other outcomes (SOR: B, 1 large RCT)

    The Wyoming Survey for H-alpha. I. Initial Results at z ~ 0.16 and 0.24

    Full text link
    The Wyoming Survey for H-alpha, or WySH, is a large-area, ground-based, narrowband imaging survey for H-alpha-emitting galaxies over the latter half of the age of the Universe. The survey spans several square degrees in a set of fields of low Galactic cirrus emission. The observing program focuses on multiple dz~0.02 epochs from z~0.16 to z~0.81 down to a uniform (continuum+line) luminosity at each epoch of ~10^33 W uncorrected for extinction (3sigma for a 3" diameter aperture). First results are presented here for 98+208 galaxies observed over approximately 2 square degrees at redshifts z~0.16 and 0.24, including preliminary luminosity functions at these two epochs. These data clearly show an evolution with lookback time in the volume-averaged cosmic star formation rate. Integrals of Schechter fits to the extinction-corrected H-alpha luminosity functions indicate star formation rates per co-moving volume of 0.009 and 0.014 h_70 M_sun/yr/Mpc^3 at z~0.16 and 0.24, respectively. The formal uncertainties in the Schechter fits, based on this initial subset of the survey, correspond to uncertainties in the cosmic star formation rate density at the >~40% level; the tentative uncertainty due to cosmic variance is 25%, estimated from separately carrying out the analysis on data from the first two fields with substantial datasets.Comment: To appear in the Astronomical Journa

    The respiratory resistance sensitivity task: An automated method for quantifying respiratory interoception and metacognition

    Full text link
    The ability to sense, monitor, and control respiration – e.g., respiratory interoception (henceforth, respiroception) is a core homeostatic ability. Beyond the regulation of gas exchange, enhanced awareness of respiratory sensations is directly related to psychiatric symptoms such as panic and anxiety. Indeed, chronic breathlessness (dyspnea) is associated with a fourfold increase in the risk of developing depression and anxiety, and the regulation of the breath is a key aspect of many mindfulness-based approaches to the treatment of mental illness. Physiologically speaking, the ability to accurately monitor respiratory sensations is important for optimizing cardiorespiratory function during athletic exertion, and can be a key indicator of illness. Given the important role of respiroception in mental and physical health, it is unsurprising that there is increased interest in the quantification of respiratory psychophysiology across different perceptual and metacognitive levels of the psychological hierarchy. Compared to other more popular modalities of interoception, such as in the cardiac domain, there are relatively few methods available for measuring aspects of respiroception. Existing inspiratory loading tasks are difficult to administer and frequently require expensive medical equipment, or offer poor granularity in their quantification of respiratory-related perceptual ability. To facilitate the study of respiroception, we here present a new, fully automated and computer-controlled apparatus and psychophysiological method, which can flexibly and easily measure respiratory-related interoceptive sensitivity, bias and metacognition, in as little as 30 min of testing, using easy to make 3D printable parts.ISSN:0301-0511ISSN:1873-624
