    Training Youth Workers for Vocational Youth Ministry: Foundations for Undergraduate Youth Ministry Degree Programs

    Get PDF
    The goal of this research project was to examine youth ministry education programs as to what is considered essential to training vocational youth ministry students in undergraduate degree programs. Questions regarding a youth ministry student’s preparedness for ministry and graduate studies have arisen. The purpose of the thesis is to propose an integrated interdisciplinary youth ministry education program for undergraduate institutions. A random survey resulted in 140 Christian Bible colleges and Liberal Arts Universities programs being examined. These institutions had 141 youth ministry education programs as one institution had two distinct programs. The youth ministry major course requirements and class descriptions were evaluated based on the institution’s catalog description of the essential coursework required for the major. These were listed under the major description. Secondly, a literature review was conducted. This review examines Dean Hoge’s study on denominational influences on youth ministry. Andrew Jack and Barrett McRay’s and Mark Cannister’s surveys results of youth ministry professors are examined. Then content was reviewed by examining textbooks available for youth ministry education in the respective interdisciplinary fields. Based on the surveys and additional research, the study makes an argument for an interdisciplinary approach to youth ministry education. It argues that a theology of community is an essential theological foundation. It argues that developmental studies should be integrated into the youth ministry education program, especially as it relates to understanding adolescent spirituality. Finally, a broad understanding of the systems that affect adolescents is essential, including ecology of human development, urban and social justice issues and skill sets are essential in youth ministry education. Finally, the study concludes with a suggestion for an integrated youth ministry education program. It proposes a theological, developmental and environmentally integrated series of courses. The appendix includes a series of suggested courses as an example. Content Reader: Dr. Chapman Clar

    A Case of Tacrolimus-Induced Posterior Reversible Encephalopathy Syndrome Initially Presenting as a Bilateral Optic Neuropathy

    Purpose: To report a case of asymmetric bilateral optic neuropathy in a patient receiving tacrolimus for immunosuppression after kidney transplantation with subsequent stroke-like symptoms of posterior reversible encephalopathy syndrome (PRES). Method: Case report. In a 54-year-old Hispanic male receiving tacrolimus after orthotropic kidney transplantation, serial ophthalmologic examinations, laboratory studies, and imaging were performed. Results: The patient had deterioration of vision in the left eye with subclinical optic neuropathy in the right eye, with clinical features resembling ischemic optic neuropathy. Additionally, he developed a change in mental state with weakness of extremities. After the cessation of tacrolimus, the visual loss remained but the other neurologic symptoms resolved. Conclusion: Tacrolimus may be associated with optic neuropathy and PRES at the initial presentation to an ophthalmologist

    Data-mining modeling for the prediction of wear on forming-taps in the threading of steel components

    An experimental approach is presented for the measurement of wear that is common in the threading of cold-forged steel. In this work, the first objective is to measure wear on various types of roll taps manufactured to tapping holes in microalloyed HR45 steel. Different geometries and levels of wear are tested and measured. Taking their geometry as the critical factor, the types of forming tap with the least wear and the best performance are identified. Abrasive wear was observed on the forming lobes. A higher number of lobes in the chamber zone and around the nominal diameter meant a more uniform load distribution and a more gradual forming process. A second objective is to identify the most accurate data-mining technique for the prediction of form-tap wear. Different data-mining techniques are tested to select the most accurate one: from standard versions such as Multilayer Perceptrons, Support Vector Machines and Regression Trees to the most recent ones such as Rotation Forest ensembles and Iterated Bagging ensembles. The best results were obtained with ensembles of Rotation Forest with unpruned Regression Trees as base regressors that reduced the RMS error of the best-tested baseline technique for the lower length output by 33%, and Additive Regression with unpruned M5P as base regressors that reduced the RMS errors of the linear fit for the upper and total lengths by 25% and 39%, respectively. However, the lower length was statistically more difficult to model in Additive Regression than in Rotation Forest. Rotation Forest with unpruned Regression Trees as base regressors therefore appeared to be the most suitable regressor for the modeling of this industrial problem.ThisinvestigationwaspartiallysupportedbyProjects TIN2011-24046,IPT-2011-1265-020000andDPI2009- 06124-E/DPIoftheSpanishMinistryofEconomyand Competitiveness.WethanktheUFIinMechanicalEngineer- ing oftheUPV/EHU(UFIMECA-1.0.2016(ext))forits support

    A Randomized Trial to Improve Adherence to Follow-up Eye Examinations Among People With Glaucoma

    Get PDF
    INTRODUCTION: Appointment nonadherence is common among people with glaucoma, making it difficult for eye care providers to monitor glaucoma progression. Our objective was to determine whether the use of patient navigators, in conjunction with social worker support, could increase adherence to recommended follow-up eye appointments. METHODS: A randomized, controlled trial evaluated the effectiveness of an intervention that used patient navigators and social workers to improve patient adherence to follow-up eye care compared with usual care. Participants with glaucoma and other eye diseases (N = 344) were identified at primary care clinics in community settings through telemedicine screening of imaging and then randomized to enhanced intervention (EI) or usual care (UC). Data on participants\u27 visits with local ophthalmologists were collected for up to 3 years from randomization. Groups were compared for timely attendance at the first visit with the local ophthalmologist and adherence to recommended follow-up visits. RESULTS: Timely attendance at the first visit was higher for EI than UC (74.4% vs 39.0%; average relative risk [aRR] = 1.85; 95% CI, 1.51-2.28; P \u3c .001). Rates of adherence to recommended annual follow-up during year 1 were 18.6% in the EI group and 8.1% in the usual care group (aRR = 2.08; 95% CI, 1.14-3.76; P = .02). The aRR across years 2 and 3 was 3.92 (95% CI, 1.24-12.43; P = .02). CONCLUSION: An intervention using patient navigators and social workers doubled the rate of adherence to annual recommended follow-up eye care compared with usual care in community settings, and was effective at increasing connections with local ophthalmologists. Interventions to further improve long-term adherence are needed

    Cutaneous lesions of the nose

    Skin diseases on the nose are seen in a variety of medical disciplines. Dermatologists, otorhinolaryngologists, general practitioners and general plastic and dermatologic surgeons are regularly consulted regarding cutaneous lesions on the nose. This article is the second part of a review series dealing with cutaneous lesions on the head and face, which are frequently seen in daily practice by a dermatologic surgeon. In this review, we focus on those skin diseases on the nose where surgery or laser therapy is considered a possible treatment option or that can be surgically evaluated
