USE OF CATCHMENT SPECIFIC SOCIAL AND ECONOMIC INFORMATION IN MANAGING NATURAL RESOURCES

Catchment specific economic and social information assists catchment management authorities in natural resource planning and decision making. It gives a context to the natural resource management (NRM) planning and decision making by providing an understanding of the economic and social characteristics in a region and tracks economic and social changes overtime. It also enables analysis of factors that influence a community’s competence in undertaking NRM activities. Catchment specific economic and social data is available from the Australian Bureau of Statistics but there are gaps in the availability of this data that may hinder NRM planning and decision making. The aim of this paper is two fold: firstly, it provides a snapshot of the economic and social information of selected catchments in NSW and secondly, it emphasises the need for further data availability that can facilitate NRM planning and decision making at a catchment level.economic, social, data availability, natural resource management, catchment management authorities, decision making, Resource /Energy Economics and Policy,

Empowering Providers to Empower Their Patients: One Model to Expand Knowledge, Competency, and Awareness for the Perinatal Substance Use Workforce

Perinatal substance use (PSU) is a serious and growing public health concern. It is associated with a variety of adverse health outcomes for both mother and child and has been shown to negatively impact the parent-child relationship. Despite the growing prevalence of PSU, there are notable deficits in provider knowledge regarding, and comfortability with, PSU. Moreover, providers report feelings of judgment, resentment, fear, and hesitancy related to their work with women with PSU. Subsequently, women with PSU struggle to find appropriate, compassionate, and effective treatment for their substance misuse. Widespread and accessible training is needed to bolster provider knowledge base, reduce stigma, shame, and increase quality of service provision and care for women with PSU. This paper aims to outline the development and structure of a PSU training to serve as a one model to expand knowledge, competency, and awareness for the PSU workforce. I begin with a review of the prevalence of PSU and its impact on maternal and infant wellbeing. Theoretical underpinnings of PSU are explored, including a specific discussion regarding the interplay between the neurobiology of addiction and the parent-child attachment system. Subsequently, the current state of the PSU workforce and the need for training is discussed. The paper ends with an in-depth review of a PSU training developed in collaboration with the University of Denver, Colorado Department of Public Health (CDPH), and the Colorado chapter of Postpartum Support International (PSI). Implications for the field and potential future directions are explored

Attempted DNA extraction from a Rancho La Brea Columbian mammoth (Mammuthus columbi): prospects for ancient DNA from asphalt deposits.

Fossil-bearing asphalt deposits are an understudied and potentially significant source of ancient DNA. Previous attempts to extract DNA from skeletons preserved at the Rancho La Brea tar pits in Los Angeles, California, have proven unsuccessful, but it is unclear whether this is due to a lack of endogenous DNA, or if the problem is caused by asphalt-mediated inhibition. In an attempt to test these hypotheses, a recently recovered Columbian mammoth (Mammuthus columbi) skeleton with an unusual pattern of asphalt impregnation was studied. Ultimately, none of the bone samples tested successfully amplified M. columbi DNA. Our work suggests that reagents typically used to remove asphalt from ancient samples also inhibit DNA extraction. Ultimately, we conclude that the probability of recovering ancient DNA from fossils in asphalt deposits is strongly (perhaps fatally) hindered by the organic compounds that permeate the bones and that at the Rancho La Brea tar pits, environmental conditions might not have been ideal for the general preservation of genetic material

Self-Efficacy and Burnout and Their Impact on School Counselors

Policymakers focused on school and mental health proposals in the wake of shooting in Newton, Connecticut. Since this incident a policy is being considered to restrict gun use and increase mental health and student support services. In 2012, the Department of Education explored five emerging issues that impact learning: (a) school discipline, (b) gender-based violence, (c) behavioral health, (d) bullying, and (e) school safety. These five issues, when they impact the learning environment, the school counselor may exhibit increased anxiety that may lead to burnout. Additionally, the school climate may be impacted by the relationship with administrators and staff. If there is a decrease in the quality of the school climate, it may impact the school counselors self-efficacy and increase burnout. Therefore, the purpose of this quantitative study was to identify how the decreasing quality of school climate and the heightened stressors can lead to burnout among counselors and burnout leads to decreased self-efficacy. Using a correlational design, the Counselor Burnout Inventory was used to measure burnout and school climate and the School Counselor Efficacy scale was used to measure self-efficacy. Both surveys was administered to 62 school counselors in elementary, middle, and high school. The data were analyzed using a multiple linear regression and analysis of variance.The findings indicated that (a) there is a relationship between self-efficacy, school climate and burnout and that (b) there was no difference between school levels for self-efficacy or burnout. One recommendation for future research is to interview administrators to establish their perceptions about school counselor burnout. Social change implications include creating healthier school counselors who can do a better job developing positive school climates which will also impact their clients

Strategies to address auditory perceptual deficits in a school of skills in the northern suburbs of Cape Town

The aim of this action research was to investigate how auditory perceptual deficits affect reading in learners with disabilities. The sub-questions were: What auditory perceptual deficits learners’ experience? How do educators assist learners with auditory perceptual deficits? What instructional strategies and classroom management can educators apply to assist learners with auditory perceptual skills? The data collections comprised of an informal oral assessment, observation and anecdotal notes with fifteen participants with barriers to learning, from the English first year class, within a special needs educational setting. Data analysis and validity were supported by triangulation through informal assessment, observation, my critical friend and my own critical reflection. The support of phonologic, memory, and cohesion skills, auditory skills were the reading educational construct and strategies used as intervention in order to identify the efficacy of said interventions. Both bottom-up and top-down support strategies were used in relation to the participants’ individualised educational needs. The research results and discussion included methods to improve reading and listening skills in the classroom environment.Inclusive EducationM. Ed. (Inclusive Education

Parents' involvement in child care: do parental and work identities matter?

The current study draws on identity theory to explore mothers' and fathers' involvement in childcare. It examined the relationships between the salience and centrality of individuals’ parental and work-related identities and the extent to which they are involved in various forms of childcare. A sample of 148 couples with at least one child aged 6 years or younger completed extensive questionnaires. As hypothesized, the salience and centrality of parental identities were positively related to mothers' and fathers' involvement in childcare. Moreover, maternal identity salience was negatively related to fathers' hours of childcare and share of childcare tasks. Finally, work hours mediated the negative relationships between the centrality of work identities and time invested in childcare, and gender moderated this mediation effect. That is, the more central a mother's work identity, the more hours she worked for pay and the fewer hours she invested in childcare. These findings shed light on the role of parental identities in guiding behavioral choices, and attest to the importance of distinguishing between identity salience and centrality as two components of self-structure

Phenotypic convergence in genetically distinct lineages of a Rhinolophus species complex (Mammalia, Chiroptera)

Phenotypes of distantly related species may converge through adaptation to similar habitats and/or because they share biological constraints that limit the phenotypic variants produced. A common theme in bats is the sympatric occurrence of cryptic species that are convergent in morphology but divergent in echolocation frequency, suggesting that echolocation may facilitate niche partitioning, reducing competition. If so, allopatric populations freed from competition, could converge in both morphology and echolocation provided they occupy similar niches or share biological constraints. We investigated the evolutionary history of a widely distributed African horseshoe bat, Rhinolophus darlingi , in the context of phenotypic convergence. We used phylogenetic inference to identify and date lineage divergence together with phenotypic comparisons and ecological niche modelling to identify morphological and geographical correlates of those lineages. Our results indicate that R. darlingi is paraphyletic, the eastern and western parts of its distribution forming two distinct non-sister lineages that diverged ~9.7 Mya. We retain R. darlingi for the eastern lineage and argue that the western lineage, currently the sub-species R . d. damarensis , should be elevated to full species status. R. damarensis comprises two lineages that diverged ~5 Mya. Our findings concur with patterns of divergence of other co-distributed taxa which are associated with increased regional aridification between 7-5 Mya suggesting possible vicariant evolution. The morphology and echolocation calls of R. darlingi and R. damarensis are convergent despite occupying different biomes. This suggests that adaptation to similar habitats is not responsible for the convergence. Furthermore, R. darlingi forms part of a clade comprising species that are bigger and echolocate at lower frequencies than R. darlingi , suggesting that biological constraints are unlikely to have influenced the convergence. Instead, the striking similarity in morphology and sensory biology are probably the result of neutral evolutionary processes, resulting in the independent evolution of similar phenotypes

Comparison of significance level at the true location using two linkage approaches: LODPAL and GENEFINDER

BACKGROUND: We compare two new software packages for linkage analysis, LODPAL and GENEFINDER. Both allow for covariate adjustment. Replicates 1 to 3 of Genetic Analysis Workshop 13 simulated data sets were used for the analyses. We described the results of searching for evidence of loci contributing to a simulated quantitative trait related to systolic blood pressure (SBP). Individuals with SBP greater than 130 mm Hg were defined as affected individuals, and all others as unaffected. Total cholesterol was treated as a covariate. RESULTS: Using LODPAL, the power of detecting one of the three major genes related to SBP is 44.4% when a LOD score of 1 is used as the cut-off point. The power of GENEFINDER is lower than that of LODPAL. It is 22.2%. CONCLUSIONS: Based on the limited comparison, LODPAL provided the more reasonable power to detect linkage compared to GENEFINDER. After adjusting for the total cholesterol covariate, the current version of both programs appeared to give a high number of false positives

What Next-Generation 21 cm Power Spectrum Measurements Can Teach Us About the Epoch of Reionization

A number of experiments are currently working towards a measurement of the 21 cm signal from the Epoch of Reionization. Whether or not these experiments deliver a detection of cosmological emission, their limited sensitivity will prevent them from providing detailed information about the astrophysics of reionization. In this work, we consider what types of measurements will be enabled by a next-generation of larger 21 cm EoR telescopes. To calculate the type of constraints that will be possible with such arrays, we use simple models for the instrument, foreground emission, and the reionization history. We focus primarily on an instrument modeled after the $\sim 0.1~\rm{km}^2$ collecting area Hydrogen Epoch of Reionization Array (HERA) concept design, and parameterize the uncertainties with regard to foreground emission by considering different limits to the recently described "wedge" footprint in k-space. Uncertainties in the reionization history are accounted for using a series of simulations which vary the ionizing efficiency and minimum virial temperature of the galaxies responsible for reionization, as well as the mean free path of ionizing photons through the IGM. Given various combinations of models, we consider the significance of the possible power spectrum detections, the ability to trace the power spectrum evolution versus redshift, the detectability of salient power spectrum features, and the achievable level of quantitative constraints on astrophysical parameters. Ultimately, we find that $0.1~\rm{km}^2$ of collecting area is enough to ensure a very high significance ($\gtrsim30\sigma$) detection of the reionization power spectrum in even the most pessimistic scenarios. This sensitivity should allow for meaningful constraints on the reionization history and astrophysical parameters, especially if foreground subtraction techniques can be improved and successfully implemented.Comment: 27 pages, 18 figures, updated SKA numbers in appendi
