    The purpose of this study was to identify issues that are considered important to the legislators and higher education leaders of Tennessee in making decisions that affect the funding of higher education. A further purpose was to identify actions that such individuals believe should be taken by higher education leaders to ensure that higher education is accountable and worthy of continued or increased financial support. Using a qualitative research design, interviews were held with 10 legislators and 6 higher education leaders selected in accordance with the concept of purposeful sampling. Legislative participants included five members from the Senate and five members from the House of Representatives. All participants served on either the Education Committee or Finance Ways and Means Committee within their chamber. Higher education leaders consisted of a university president, the President of the University of Tennessee System, Chancellor of the Tennessee Board of Regents, Executive Director of the Tennessee Higher Education Commission, Comptroller of the Treasury, and a member of the University of Tennessee Board of Trustees. Issues identified from the interviews were reduced to eight categories: (a) issues affecting higher education and (b) findings regarding the accountability of higher education. The issues category was divided into eight categories: (a) financial issues that was further subdivided into funding issues, accountability issues, capital expenditures, taxes, fees, and other general financial issues; (b) administrative structure and costs; (c) quality outcomes; (d) faculty issues; (e) technology; (f) program duplication; (g) relationship to K-12 education; and (h) other general issues. Issues that emerged related to accountability included the measurement of educational outcomes and the communication of those results to legislators and the public. Based on the findings of this study, three recommendations are offered: (1) a committee consisting of appropriate representatives should be established to study the issue of accountability and determine appropriate measurements that will provide relevant information; (2) leaders in higher education should make a concerted effort to improve communication with legislators and their staffs; and (3) those in higher education must improve their communication with the public

    This study was conducted to determine if seventh and eighth grade students could develop keyboarding on the microcomputer using the computer-assisted method of instruction with minimal teacher interaction as effectively as students on electric typewriters using the traditional method of instruction. Specifically, an effort was made to determine the following difference between the computer-assisted method of instruction group and the traditional method of instruction group: gross words typed on straight-copy timed writings per minute, number of errors made on straight-copy timed writings, and technique on straight-copy. The data were made up of gross word per minute and accuracy scores on straight-copy timed writings of one to three minute duration achieved by the experimental group and control group. A rating sheet was used to gather information concerning technique. Based on the data collected, the findings of this study are as follows: There was no significant difference in accuracy between the two groups. There was a significant difference in gross words per minute typed. There was no difference in technique between the two groups. Based on the findings the following conclusions are made: Keyboarding can be taught using the computer-assisted method of instruction. Accuracy can be taught as effectively by the computer-assisted method of instruction as the traditional method of instruction. The computer-assisted method of instruction did not result in as high a speed as the traditional method of instruction. Teacher interaction was minimal with the computer-assisted method of instruction group which may have resulted in lower speed for this group. Technique can be taught as effectively using pictorial demonstration on the microcomputer as well as using teacher demonstration in the traditional method of instruction. Based on the findings and conclusions, the following recommendations are made: Additional research should be conducted to determine the effect of teacher interaction on speed scores. Additional research should be completed with keyboarding software packages to determine if daily lessons should place more emphasis on speed. Additional studies should be conducted concerning the teaching of keyboarding on the microcomputer

    Discrimination of unitary transformations in the Deutsch-Jozsa algorithm

    Full text link
    We describe a general framework for regarding oracle-assisted quantum algorithms as tools for discriminating between unitary transformations. We apply this to the Deutsch-Jozsa problem and derive all possible quantum algorithms which solve the problem with certainty using oracle unitaries in a particular form. We also use this to show that any quantum algorithm that solves the Deutsch-Jozsa problem starting with a quantum system in a particular class of initial, thermal equilibrium-based states of the type encountered in solution state NMR can only succeed with greater probability than a classical algorithm when the problem size exceeds n105.n \sim 10^5.Comment: 7 pages, 1 figur

    Land application of lime amended biosolids.

    Increased nutrient levels in inland waterways have led to algal blooms and eutrophication in many agricultural regions. To ensure fertiliser inputs are managed more effectively, the source of contamination needs to be tracked and identified. Point sources could include inorganic fertilisers, livestock excreta, or more recently biosolids. The presence of faecal indicator microorganisms has been widely used to identify the presence of faeces, however, these methods cannot distinguish between human and animals samples. This study investigated PCR amplification as a molecular method to distinguish biosolids from livestock faeces of biosolids, cattle, sheep, poultry and kangaroo. This was achieved using published priming sequences and restriction site profiling of amplified DNA across the 16S rRNA gene of anaerobic gastrointestinal bacteria Bacteroides spp and Bifidobacteria spp. Preliminary investigation showed that of the three Bacteroides spp primer pairs investigated, two were useful for cow faecal material; though at lower annealing temperatures were also applicable to biosolids and sheep faecal material. The third primer pair was specific only for biosolids. All three primer pairs were unable to PCR-amplify Bacteroides spp sequences in faecal material of kangaroo. Of the three Bifidobacteria spp primer pairs, one was useful for sheep faecal material; though at lower annealing temperature was also applicable to biosolids and cow and kangaroo faecal material. The Bifidobacterium angulatum specific primer pair enabled the PCR detection of anaerobes only in biosolids and faecal material of kangaroo. The third, a Bifidobacterium catenulatum specific primer pair was suitable for faecal material of cow and at lower annealing temperatures was also applicable to the sample from sheep. Varying degrees of success were observed in faecal material from other animals. Generally, biosolids tested positive for Bacteroides and Bfidobacteria with all primers except for those specific for B. angulatum. For some primer sets, PCR amplification alone could not differentiate biosolids from other faecal samples. The serial dilution of water contaminated by a range of livestock excreta and biosolids is being examined further to enable the sensitivity of this method to be applied in the field.Soil acidification is an increasing problem throughout many agricultural regions in Australia typically on lighter-textured soils that have a low buffering capacity to changes in soil pH and/or that may be naturally acidic. Crops and pastures grown on acidic soils are subject to problems such as aluminium toxicity (particularly in the subsoil), nodulation failure in legumes and a reduced availability of some nutrients. Lime and dolomite are products that are commonly applied to neutralise soil acidity and improve plant productivity with application rates often determined by their neutralising value and particle size of the product, and the pH buffering capacity (lime requirement) of the soil. To investigate the effect of lime amended biosolids (LAB) as a product for neutralising soil acidity and for improving crop growth, four rates of LAB (0, 5, 10 and 15 t DS/ha) and four equivalent rates of lime product (0, 2.3, 4.6 and 6.7 t/ha) were applied to an acidic red/brown sandy loam in the central wheatbelt of Western Australia. In addition, one rate of dewatered biosolids cake (DBC) at 7 t DS/ha was included to enable comparison to be made to this product. The experiment was conducted over three years and sown to wheat (Triticum aestivum), canola (Brassica napus) and then wheat in 2005, 2006 and 2007, respectively. Plants were sampled at 8 weeks and at harvest to determine the effect of LAB, lime and DBC on crop growth, nutrient uptake and grain yield. Samples of surface soil (0-10 cm) were collected and analysed at harvest for pH and major nutrients. Soil pH increased significantly with increasing rates of LAB or lime at the end of the first year, with similar values recorded between equivalent values of lime product. There was no significant change in soil pH following the addition of the DBC treatment. No further changes in soil pH had occurred by the end of the second year. The growth of both wheat and canola in the first two years was affected to a greater extent by nutrients (typically nitrogen) in the LAB than by the reduction in soil acidity. Measurements on wheat yield in the third year of the experiment and changes in soil pH in the surface (0-10 cm) and subsoil (10-20 cm) will provide further information as to the long term effects of LAB in agriculture and allow recommendations to be made regarding best practise land application rates

    Scaling issues in ensemble implementations of the Deutsch-Jozsa algorithm

    Full text link
    We discuss the ensemble version of the Deutsch-Jozsa (DJ) algorithm which attempts to provide a "scalable" implementation on an expectation-value NMR quantum computer. We show that this ensemble implementation of the DJ algorithm is at best as efficient as the classical random algorithm. As soon as any attempt is made to classify all possible functions with certainty, the implementation requires an exponentially large number of molecules. The discrepancies arise out of the interpretation of mixed state density matrices.Comment: Minor changes, reference added, replaced with publised versio

    Gaps in accessing treatment for anxiety and depression: challenges for the delivery of care.

    Get PDF
    Epidemiological studies have identified high prevalence rates of anxiety and depression in North America [e.g., J. of Nerv. Ment. Dis. 182 (1994) 290]. However, only a small percentage of these individuals access effective treatment. The undertreatment of anxiety and depression is a major public health issue and is associated with significant personal, social, and economic burden. This article describes the existing discrepancy between prevalence of anxiety and depression and access to effective treatment for adults and children, the contributors to this discrepancy, and suggests various means through which access to effective treatment may be enhanced. We begin with a brief overview of the prevalence and associated personal, societal, and systemic burdens of anxiety and depression. This is followed by a review of current rates of access to treatment and possible individual, provider, and systemic barriers to accessing treatment. Recommendations for bridging the gap between the high rates of these disorders and limited accessibility of effective care are then presented

    We derive the 'separate universe' method for the inflationary bispectrum, beginning directly from a field-theory calculation. We work to tree-level in quantum effects but to all orders in the slow-roll expansion, with masses accommodated perturbatively. Our method provides a systematic basis to account for novel sources of time-dependence in inflationary correlation functions, and has immediate applications. First, we use our result to obtain the correct matching prescription between the 'quantum' and 'classical' parts of the separate universe computation. Second, we elaborate on the application of this method in situations where its validity is not clear. As a by-product of our calculation we give the leading slow-roll corrections to the three-point function of field fluctuations on spatially flat hypersurfaces in a canonical, multiple-field model.Comment: v1: 33 pages, plus appendix and references; 5 figures. v2: typographical typos fixed, minor changes to the main text and abstract, reference added; matches version published in JCA

    Multifunctional Tanks for Spacecraft

    Get PDF
    A document discusses multifunctional tanks as means to integrate additional structural and functional efficiencies into designs of spacecraft. Whereas spacecraft tanks are traditionally designed primarily to store fluids and only secondarily to provide other benefits, multifunctional tanks are designed to simultaneously provide multiple primary benefits. In addition to one or more chamber(s) for storage of fluids, a multifunctional tank could provide any or all of the following: a) Passageways for transferring the fluids; b) Part or all of the primary structure of a spacecraft; c) All or part of an enclosure; d) Mechanical interfaces to components, subsystems, and/or systems; e) Paths and surfaces for transferring heat; f)Shielding against space radiation; j) Shielding against electromagnetic interference; h) Electrically conductive paths and surfaces; and i) Shades and baffles to protect against sunlight and/or other undesired light. Many different multifunctional-tank designs are conceivable. The design of a particular tank can be tailored to the requirements for the spacecraft in which the tank is to be installed. For example, the walls of the tank can be flat or curved or have more complicated shapes, and the tank can include an internal structure for strengthening the tank and/or other uses
