Benefits of dance education : the perceptions of college dance students

The purpose of this study was to examine college dance students\u27 perceptions of the contributions of dance education to their lives. Its primary goal was to develop a picture of the benefits of dance through the thoughts and words of dancers. An open-ended dance questionnaire designed to ascertain the students\u27 thoughts on the benefits of dance education in their lives and a demographic questionnaire designed to provide information on the dancers\u27 levels of ability were administered to dance students at a major University in the Southeast United States. Eighty-six and eight tenths percent of the students enrolled in dance classes completed the questionnaire. Each of the student\u27s responses were coded and then categorized. Similar answers were grouped into sub-categories that were then placed under larger general categories. The percentages were calculated for the advanced, intermediate, and beginner levels under each sub-category. This study answered the following research questions: I) What are the life long benefits of dance training as perceived by mature students of dance? 2) Are the perceived benefits of dance training different for dancers of different levels of ability? 3) What makes dance a valuable option for physical fitness? and 4) Has dance training influenced students to include physical fitness in their lives? The answers provided by the students fell under the three major categories of emotional, intellectual, and physical benefits. Dancers from advanced, intermediate and beginner levels reported benefits from all three categories. The differences between groups were in the degree of importance upon which they placed the emotional, intellectual, and physical benefits. This study revealed the physical benefits of dance as well as the additional emotional and intellectual benefits. The answers provided by the study\u27 s participants showed that dance provides an emotional outlet in the form of stress relief and personal expression for many dancers. The physical benefits reported by the dancers included improved physical fitness, increased body awareness, and an increased motivation to maintain a higher fitness level. Intellectual benefits included the development of time management skills, concentration skills, and self-regulation. This study concludes that the combined physical, intellectual, and emotional benefits of dance can contribute to a person\u27s overall health and well being

A Study Of The Prairie View English Placement Test 1937-38

The testing program in English at Prairie View College has been carried on regularly over a period of nine years. It has consisted of the giving of entrance placement tests on the basis of which the department tried to section students according to ability levels. For the most part commercial standardized achievement tests, chiefly the Barrette- Byan, have been used. About six years ago members of Department constructed a placement test in an attempt to set up its own standards for placement and promotion. In 1937 an altogether new and more satisfactory test was devised. The department plans to issue a new form of the test each year. Already a second form of this test has been devised. In September 1937 form I of the test was given to entering freshmen at Prairie View College. The same group took the teat again in February. (A partial report on the results of this test is included in this study.) Purpose: The purpose of this thesis was to administer form I of the new Prairie View English Placement Test to senior high school stud onto of the State in order to help establish norms for the test

"Taking your place at the table": an autoethnographic study of chaplains' participation on an interdisciplinary research team.

BackgroundThere are many potential benefits to chaplaincy in transforming into a "research-informed" profession. However little is known or has been documented about the roles of chaplains on research teams and as researchers or about the effects of research engagement on chaplains themselves. This report describes the experience and impact of three chaplains, as well as tensions and challenges that arose, on one particular interdisciplinary team researching a spiritual assessment model in palliative care. Transcripts of our research team meetings, which included the three active chaplain researchers, as well as reflections of all the members of the research team provide the data for this descriptive, qualitative, autoethnographic analysis.MethodsThis autoethnographic project evolved from the parent study, entitled "Spiritual Assessment Intervention Model (AIM) in Outpatient Palliative Care Patients with Advanced Cancer." This project focused on the use of a well-developed model of spiritual care, the Spiritual Assessment and Intervention Model (Spiritual AIM). Transcripts of nine weekly team meetings for the parent study were reviewed. These parent study team meetings were attended by various disciplines and included open dialogue and intensive questions from non-chaplain team members to chaplains about their practices and Spiritual AIM. Individual notes (from reflexive memoing) and other reflections of team members were also reviewed for this report. The primary methodological framework for this paper, autoethnography, was not only used to describe the work of chaplains as researchers, but also to reflect on the process of researcher identity formation and offer personal insights regarding the challenges accompanying this process.ResultsThree major themes emerged from the autoethnographic analytic process: 1) chaplains' unique contributions to the research team; 2) the interplay between the chaplains' active research role and their work identities; and 3) tensions and challenges in being part of an interdisciplinary research team.ConclusionsDescribing the contributions and challenges of one interdisciplinary research team that included chaplains may help inform chaplains about the experience of participating in research. As an autoethnographic study, this work is not meant to offer generalizable results about all chaplains' experiences on research teams. Research teams that are interdisciplinary may mirror the richness and efficacy of clinical interdisciplinary teams. Further work is needed to better characterize both the promise and pitfalls of chaplains' participation on research teams

Just what the doctor ordered: An evaluation of provider preference-based Instrumental Variable methods in observational studies, with application for comparative effectiveness of type 2 diabetes therapy

Instrumental Variables provide a way of addressing bias due to unmeasured confounding when estimating treatment effects using observational data. As instrument prescription preference of individual healthcare providers has been proposed. Because prescription preference is hard to measure and often unobserved, a surrogate measure constructed from available data is often required for the analysis. Different construction methods for this surrogate measure are possible, such as simple rule-based methods which make use of the observed treatment patterns, or more complex model-based methods that employ formal statistical models to explain the treatment behaviour whilst considering measured confounders. The choice of construction method relies on aspects like data availability within provider, missing data in measured confounders, and possible changes in prescription preference over time. In this paper we conduct a comprehensive simulation study to evaluate different construction methods for surrogates of prescription preference under different data conditions, including: different provider sizes, missing covariate data, and change in preference. We also propose a novel model-based construction method to address between provider differences and change in prescription preference. All presented construction methods are exemplified in a case study of the relative glucose lowering effect of two type 2 diabetes treatments in observational data. Our study shows that preference-based Instrumental Variable methods can be a useful tool for causal inference from observational health data. The choice of construction method should be driven by the data condition at hand. Our proposed method is capable of estimating the causal treatment effect without bias in case of sufficient prescription data per provider, changing prescription preference over time and non-ignorable missingness in measured confounders.Comment: 44 pages, 11 figure

DNA Damage and Cytokine Production in Non-Target Irradiated Lymphocytes

In advanced radiotherapy, treatment of the tumor with high-intensity modulated fields is balanced with normal tissue sparing. However, the non-target dose delivered to surrounding healthy tissue within the irradiated volume is a potential cause for concern. Whether the effects observed are caused after exposure to out-of-field radiation or bystander effects through neighboring irradiated cells is not fully understood. The goal of this study was to determine the effect of exposure to out-of-field radiation in lymphocyte cell lines and primary blood cells. The role of cellular radiosensitivity in altering bystander responses in out-of-field exposed cells was also investigated. Target cells were positioned in a phantom in the center of the radiation field (in-field dose) and exposed to 2 Gy irradiation. Lymphocyte cell lines (C1, AT3ABR, Jurkat, THP-1, AT2Bi and AT3Bi) and peripheral blood were placed 1 cm away from the radiation field edge (out-offield dose) and received an average dose of 10.8 6 4.2 cGy. Double-stranded DNA damage, cell growth and gene expression were measured in the out-of-field cells. Radiosensitive AT3ABR and primary blood cells demonstrated the largest increase in c-H2AX foci after irradiation. Exposure of normal cells to bystander factors from irradiated radiosensitive cell lines also increased DNA damage. Expression of IL-1, IL-6, TNFa and TGFb after addition of bystander factors from radiosensitive cells showed differential effects in normally responding cells, with some evidence of an adaptive response observed. Exposure to out-of-field radiation induces DNA damage and reduces growth in radiosensitive cells. Bystander factors produced by directly irradiated cells in combination with out-of-field exposure may upregulate pro- and anti-inflammatory genes in responding cells of different radiosensitivities, with the potential of affecting the tumor microenvironment. A greater understanding of the radiobiological response in normal cells outside the primary treatment field would assist in radiation treatment planning and in reducing early and late toxicities

A school-based program to prevent depressive symptoms and strengthen well-being among pre-vocational students (Happy Lessons):protocol for a cluster randomized controlled trial and implementation study

BACKGROUND: Depression is one of the leading causes of illness and disability among young people. In the Netherlands, one in twelve Dutch adolescents has experienced depression in the last 12 months. Pre-vocational students are at higher risk for elevated depressive symptoms. Effective interventions, especially for this risk group, are therefore needed to prevent the onset of depression or mitigate the adverse long-term effects of depression. The aim of this study is to examine the effectiveness and implementation of a school-based program Happy Lessons (HL), that aims to prevent depression and promote well-being among pre-vocational students. METHODS: A cluster randomized controlled trial (RCT) with students randomized to HL or to care as usual will be conducted. Pre-vocational students in their first or second year (aged 12 to 14) will participate in the study. Subjects in both conditions will complete assessments at baseline and at 3- and 6-months follow-up. The primary outcome will be depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CES-D) at 6-months follow-up. Secondary outcomes are well-being using the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) and life satisfaction (Cantril Ladder) measured at 6-months follow-up. Alongside the trial, an implementation study will be conducted to evaluate the implementation of HL, using both quantitative and qualitative methods (interviews, survey, and classroom observations). DISCUSSION: The results from both the RCT and implementation study will contribute to the limited evidence base on effective school-based interventions for the prevention of depression and promotion of well-being among pre-vocational adolescents. In addition, insights from the implementation study will aid identifying factors relevant for optimizing the future implementation and scale-up of HL to other schools and contexts. TRIAL REGISTRATION: This study was registered on 20 September 2021 in the Dutch Trial Register (NL9732).

Application of Advanced Non-Linear Spectral Decomposition and Regression Methods for Spectroscopic Analysis of Targeted and Non-Targeted Irradiation Effects in an In-Vitro Model

Irradiation of the tumour site during treatment for cancer with external-beam ionising radiation results in a complex and dynamic series of effects in both the tumour itself and the normal tissue which surrounds it. The development of a spectral model of the effect of each exposure and interaction mode between these tissues would enable label free assessment of the effect of radiotherapeutic treatment in practice. In this study Fourier transform Infrared microspectroscopic imaging was employed to analyse an in-vitro model of radiotherapeutic treatment for prostate cancer, in which a normal cell line (PNT1A) was exposed to low-dose X-ray radiation from the scattered treatment beam, and also to irradiated cell culture medium (ICCM) from a cancer cell line exposed to a treatment relevant dose (2 Gy). Various exposure modes were studied and reference was made to previously acquired data on cellular survival and DNA double strand break damage. Spectral analysis with manifold methods, linear spectral fitting, non-linear classification and non-linear regression approaches were found to accurately segregate spectra on irradiation type and provide a comprehensive set of spectral markers which differentiate on irradiation mode and cell fate. The study demonstrates that high dose irradiation, low-dose scatter irradiation and radiation-induced bystander exposure (RIBE) signalling each produce differential effects on the cell which are observable through spectroscopic analysis

MicroRNA Analysis of ATM-Deficient Cells Indicate PTEN and CCDN1 as Potential Biomarkers of Radiation Response

Genetic and epigenetic profile changes associated with individual radiation sensitivity are well documented and have led to enhanced understanding of the mechanisms of the radiation-induced DNA damage response. However, the search continues to identify reliable biomarkers of individual radiation sensitivity. Herein, we report on a multi-biomarker approach using traditional cytogenetic biomarkers, DNA damage biomarkers and transcriptional microRNA (miR) biomarkers coupled with their potential gene targets to identify radiosensitivity in ataxia-telangiectasia mutated (ATM)-deficient lymphoblastoid cell lines (LCL); ATM-proficient cell lines were used as controls. Cells were 0.05 and 0.5 Gy irradiated, using a linear accelerator, with sham-irradiated cells as controls. At 1 h postirradiation, cells were fixed for γ-H2AX analysis as a measurement of DNA damage, and cytogenetic analysis using the G2 chromosomal sensitivity assay, G-banding and FISH techniques. RNA was also isolated for genetic profiling by microRNA (miR) and RT-PCR analysis. A panel of 752 miR were analyzed, and potential target genes, phosphatase and tensin homolog (PTEN) and cyclin D1 (CCND1), were measured. The cytogenetic assays revealed that although the control cell line had functional cell cycle checkpoints, the radiosensitivity of the control and AT cell lines were similar. Analysis of DNA damage in all cell lines, including an additional control cell line, showed elevated γ-H2AX levels for only one AT cell line. Of the 752 miR analyzed, eight miR were upregulated, and six miR were downregulated in the AT cells compared to the control. Upregulated miR-152-3p, miR-24-5p and miR-92-15p and all downregulated miR were indicated as modulators of PTEN and CCDN1. Further measurement of both genes validated their potential role as radiation-response biomarkers. The multi-biomarker approach not only revealed potential candidates for radiation response, but provided additional mechanistic insights into the response in AT-deficient cells

Cross-Species Genome-Wide Analysis Reveals Molecular and Functional Diversity of the Unconventional Interferon-ω Subtype

Innate immune interferons (IFNs), particularly type I IFNs, are primary mediators regulating animal antiviral, antitumor, and cell-proliferative activity. These antiviral cytokines have evolved remarkable molecular and functional diversity to confront ever-evolving viral threats and physiological regulation. We have annotated IFN gene families across 110 animal genomes, and showed that IFN genes, after originating in jawed fishes, had several significant evolutionary surges in vertebrate species of amphibians, bats and ungulates, particularly pigs and cattle. For example, pigs have the largest but still expanding type I IFN family consisting of nearly 60 IFN-coding genes that encode seven IFN subtypes including multigene subtypes of IFN-α, -δ, and -ω. Whereas, subtypes such as IFN-α and -β have been widely studied in many species, the unconventional subtypes such as IFN-ω have barely been investigated. We have cross-species defined the IFN evolution, and shown that unconventional IFN subtypes particularly the IFN-ω subtype have evolved several novel features including: (1) being a signature multi-gene subtype expanding primarily in mammals such as bats and ungulates, (2) emerging isoforms that have superior antiviral potency than typical IFN-α, (3) highly cross-species antiviral (but little anti-proliferative) activity exerted in cells of humans and other mammalian species, and (4) demonstrating potential novel molecular and functional properties. This study focused on IFN-ω to investigate the immunogenetic evolution and functional diversity of unconventional IFN subtypes, which may further IFN-based novel antiviral design pertinent to their cross-species high antiviral and novel activities
