    Self-responsibility study initially outlined the importance of ‘self-directed Adult learning’ either as the method or the outcome of education. Attention was given to the different interest of individual’s in accepting responsibility for their professional development. In this regard, several sources reveal the need for learners to take their own responsibility for developing employability competencies development. However, the concern must be expressed at the incompleteness of research into the personal responsibility for competency development

    Perfect Sampling with Unitary Tensor Networks

    Tensor network states are powerful variational ans\"atze for many-body ground states of quantum lattice models. The use of Monte Carlo sampling techniques in tensor network approaches significantly reduces the cost of tensor contractions, potentially leading to a substantial increase in computational efficiency. Previous proposals are based on a Markov chain Monte Carlo scheme generated by locally updating configurations and, as such, must deal with equilibration and autocorrelation times, which result in a reduction of efficiency. Here we propose a perfect sampling scheme, with vanishing equilibration and autocorrelation times, for unitary tensor networks -- namely tensor networks based on efficiently contractible, unitary quantum circuits, such as unitary versions of the matrix product state (MPS) and tree tensor network (TTN), and the multi-scale entanglement renormalization ansatz (MERA). Configurations are directly sampled according to their probabilities in the wavefunction, without resorting to a Markov chain process. We also describe a partial sampling scheme that can result in a dramatic (basis-dependent) reduction of sampling error.Comment: 11 pages, 9 figures, renamed partial sampling to incomplete sampling for clarity, extra references, plus a variety of minor change

    Listening to Movement: The Use of Dance Movement Therapy in Groups to Reduce Anxiety in Males Struggling with Addiction

    Get PDF
    A study with the use of dance movement therapy as a counseling approach in a chemical dependency setting was presented. The objective of the study was to find out if the use of dance movement therapy in male chemical dependency groups reduces overall anxiety. The literature review describes dance movement therapy, aspects of chemical dependency and addiction, dance movement therapy used with specific populations, chemical addiction with creative art therapies, the process of recovery (stages of change), fundamentals of group work, anxiety, and movement therapy techniques used in chemical dependency groups. Methods of the study were presented with the use of four movement therapy interventions. The instrument and participants were also described. The results were evaluated qualitatively and quantitatively through pre and post test results and observations. The discussion presents areas for additional research and implications for future research

    Bridging Inequity Through Farmer’s Market Mobility: Food Access Barriers and Alternative Food Systems in Kingston, New York

    Get PDF
    Low-income communities in the United States face disproportionately higher levels of food access barriers than other demographics in the country. Flawed public transportation systems, high cost, inefficient government food assistance programs, and structural exclusivity have created a food system that is largely inaccessible for many low-income individuals. This project demonstrates existing inequity in our food systems and illustrates the ways and which it is experienced by low-income demographics. It describes ways that geographic and physical space, economics, policy, and socio-cultural components impact food access experiences, and the ways these components impact choice and decision-making. While the existing system is unjust and inequitable, alternative food systems can create and foster equity and resiliency. This project illustrates existing exclusivity in alternative food systems, while advocating for their necessity in creating broad systematic change. They must be redefined and recreated as inclusive, community systems, and through this, they have the potential to foster community, create resiliency local food systems, and increase equity. This project uses Kingston, New York as a case study to examine existing barriers and the potential for farmer’s markets and urban farms, such as the Kingston YMCA Farm Project to mitigate food access barriers

    A biophysical model of prokaryotic diversity in geothermal hot springs

    Recent field investigations of photosynthetic bacteria living in geothermal hot spring environments have revealed surprisingly complex ecosystems, with an unexpected level of genetic diversity. One case of particular interest involves the distribution along hot spring thermal gradients of genetically distinct bacterial strains that differ in their preferred temperatures for reproduction and photosynthesis. In such systems, a single variable, temperature, defines the relevant environmental variation. In spite of this, each region along the thermal gradient exhibits multiple strains of photosynthetic bacteria adapted to several distinct thermal optima, rather than the expected single thermal strain adapted to the local environmental temperature. Here we analyze microbiology data from several ecological studies to show that the thermal distribution field data exhibit several universal features independent of location and specific bacterial strain. These include the distribution of optimal temperatures of different thermal strains and the functional dependence of the net population density on temperature. Further, we present a simple population dynamics model of these systems that is highly constrained by biophysical data and by physical features of the environment. This model can explain in detail the observed diversity of different strains of the photosynthetic bacteria. It also reproduces the observed thermal population distributions, as well as certain features of population dynamics observed in laboratory studies of the same organisms

    A Comparison of a Full Time Grazing and a Partial Storage Feeding System, for Dairy Cows

    Get PDF
    Partial storage feeding has been adopted by a number of Northern Ireland dairy farmers in recent years. This is due in part to increasing cow numbers, and as such, insufficient pasture close to the milking parlour to permit full time grazing. Partial storage feeding may also have environmental benefits, as well as reducing labour requirements associated with \u27droving\u27 and pasture management. In view of this, a study was undertaken to examine animal performance with either a full-time grazing, or a partial storage feeding regime
