    This qualitative study takes a deeper look into the lived experiences of students in southeast Kansas who have dropped out of high school. As a result, school and community leaders are better informed to create effective strategy, policy, and practice in dropout prevention. Framed as a phenomenology, data was collected by conducting in-depth, face-to-face interviews with 12 participants and a focus-group interview with four participants. The researcher administered a survey/questionnaire to an additional 15 participants. Utilizing the Streamlined Codes-To-Theory Model (Saldana, 2009); organizational, structural, and elaborative coding techniques were implemented to reduce the data into categories, which led to the establishment of common themes and conclusions for the study. The findings indicate the most common reasons participants share for their decision to drop out relates to negative school experiences, followed closely by life-events occurring outside of the school culture. Many participants stated that there was nothing anyone could have said or done to keep them in school; however, almost half said they might have been persuaded to stay in school if conditions were different. The overriding conclusion was that students who dropped out lacked the appropriate motivation to finish or complete the desired goal, to graduate. This was explained by applying the Expectancy-Value Theory of Achievement Motivation (Keller, 1987) to the study. This study concludes that dropout can be reduced by increasing the value a student places in having an education or being connected to the school. Further, chances of completing the diploma requirements can be greatly enhanced by increasing students\u27 confidence in their own ability to be successful

    Purpose: After-hours social work (SW) services seem to be provided in many major healthcare centres but there appear to be no data describing these services, in terms of the number of patients seen, their characteristics, types of problems, SW interventions provided, their effectiveness or the impact of providing after-hours services on the provider. The aim of this study was to investigate the patient characteristics and types of interventions provided to patients who received an after-hours SW service and the effect of providing these services on the service-provider. Method: A retrospective review of data collected on patients who had received after-hours SW service for urgent/crisis scenarios over a three-year period in a tertiary-care public hospital in Australia was undertaken, with two illustrative case scenarios. Results: A total of 172 occasions of service were delivered, with most services provided to patients/families in the Emergency Department (ED) or Intensive Care Unit (ICU) following trauma or with a medical condition. Counselling for trauma, grief or loss were the types of interventions most often provided. Interventions were most frequently rated by the SW-provider as highly complex and imperative. At times, providing the after-hours service negatively impacted on the service-provider the following day, with tiredness and hypervigilance most frequently reported. Conclusion: An after-hours SW service within a tertiary-care hospital was provided approximately five times/month, predominantly involving counselling to patients/families in the ED or ICU, and rated as highly complex and imperative. These results provide evidence, albeit anecdotal, that an after-hours SW service is of value in this setting

    Flight Control Design for a Tailless Aircraft Using Eigenstructure Assignment

    We apply eigenstructure assignment to the design of a flight control system for a wind tunnel model of a tailless aircraft. The aircraft, known as the innovative control effectors (ICEs) aircraft, has unconventional control surfaces plus pitch and yaw thrust vectoring. We linearize the aircraft in straight and level flight at an altitude of 15,000 feet and Mach number 0.4. Then, we separately design flight control systems for the longitudinal and lateral dynamics. We use a control allocation scheme with weights so that the lateral pseudoinputs are yaw and roll moment, and the longitudinal pseudoinput is pitching moment. In contrast to previous eigenstructure assignment designs for the ICE aircraft, we consider the phugoid mode, thrust vectoring, and stability margins. We show how to simultaneously stabilize the phugoid mode, satisfy MIL-F-8785C mode specifications, and satisfy MIL-F-9490D phase and gain margin specifications. We also use a cstar command system that is preferable to earlier pitch-rate command systems. Finally, we present simulation results of the combined longitudinal/lateral flight control system using a full 6DOF nonlinear simulation with approximately 20,000 values for the aerodynamic coefficients. Our simulation includes limiters on actuator deflections, deflection rates, and control system integrators
