Helping Children Find a Home that Offers Safety, Stability, and Love
The researcher wanted to look closely to see if preferences of adoptive parents, such as a particular race, age, or gender of the adoptee, helped or hindered the process of adoption. Gathering research, based on previous studies, the researcher was able to compare and contrast, to see if there are any patterns regarding adoptive parent preferences. There was a hole in the literature in regards to the preference of gender. This was a quantitative descriptive study completed by Providence College students, using a Likert-like style instrument. The main findings in the research was the statistically significant relationship of the values of the variable race and age, based on their preference of an adoptee. Implications for further research, would be that more studies should be done to identify other variables affecting the decline in adoption, and ways to successfully move forward from this decline
Study of operational parameters impacting helicopter fuel consumption
A computerized study of operational parameters affecting helicopter fuel consumption was conducted as an integral part of the NASA Civil Helicopter Technology Program. The study utilized the Helicopter Sizing and Performance Computer Program (HESCOMP) developed by the Boeing-Vertol Company and NASA Ames Research Center. An introduction to HESCOMP is incorporated in this report. The results presented were calculated using the NASA CH-53 civil helicopter research aircraft specifications. Plots from which optimum flight conditions for minimum fuel use that can be obtained are presented for this aircraft. The results of the study are considered to be generally indicative of trends for all helicopters
What roles and functions have been identified by empirical research for material objects later in life?
Introduction: Moving house later in life can be a major transition. Some studies have identified valued objects may be important to this process however the significance of objects is not well understood and related psychological theory is limited. As such, the present study aimed to build an explanatory model for the significance of valued objects to older adults in the context of a residential transition.
Method: 11 older adults, and 1 care home manager were interviewed about the meanings and roles of valued material objects following a residential transition. Older adult participants lived in either their own home, or a care home. Grounded theory method was used to build a theory of the value of objects for older adults following a residential transition.
Results: The theory proposes valued objects are associated with at least one of five key constructs; properties of objects, emotions, memory, connection, and legacy. The model also depicts the process of residential transition which is characterised by making decisions about objects.
Conclusion: Valued objects have important meanings and roles for older adults following a residential transition. Losing objects can result in emotional pain and potentially separate people from making use of objects to adjust and reflect on their move. Clinical recommendations include providing information to support people with making decisions about objects when moving house, and exploring the topic of valued objects with older adults when working therapeutically
Covering Kids & Families Evaluation: Expectations of Sustainability: What Do CKF Grantees and State Officials Predict Will Happen Once RWJF Funding Ends?
Based on a survey of CKF state grantees and Medicaid and Children's Health Insurance Program officials, examines prospects for continuing efforts to increase enrollment, factors contributing to survival, alternative funding sources, and priorities
Covering Kids & Families Evaluation: Improving Medicaid and SCHIP Through Simplification and Coordination
Based on a survey of CKF state grantees and Medicaid and Children's Health Insurance Program officials, outlines procedural simplifications and better coordination achieved to improve programs and increase enrollment, CKF's role, and contributing factors
Outliving Grant Funding: A Review of State CKF Projects and Coalitions and the Roles of Funding and In-Kind Support in Their Survival
Examines how the requirements built into RWJF's grants for projects to increase enrollment in Medicaid and State Children's Health Insurance Programs affected the sustainability, evolution, and activities of grantees and coalitions after the grants ended
Study of the mapping of Navier-Stokes algorithms onto multiple-instruction/multiple-data-stream computers
Implicit approximate-factored algorithms have certain properties that are suitable for parallel processing. A particular computational fluid dynamics (CFD) code, using this algorithm, is mapped onto a multiple-instruction/multiple-data-stream (MIMD) computer architecture. An explanation of this mapping procedure is presented, as well as some of the difficulties encountered when trying to run the code concurrently. Timing results are given for runs on the Ames Research Center's MIMD test facility which consists of two VAX 11/780's with a common MA780 multi-ported memory. Speedups exceeding 1.9 for characteristic CFD runs were indicated by the timing results
The 20/30 GHz satellite systems technology needs assessment
Rain attenuation in the 20/30 GHz bands, and the resultant impact on system user costs were estimated for a variety of satellite communication system concepts. Results of previous and current NASA Lewis contractual and in-house studies on system design are reported as well as market studies conducted to evaluate the concepts and test their relevancy against forecasted market needs. The 20/30 GHz bands appear attractive economically and, with certain technology, appear to offer a virtually unlimited spectrum resource. This attractiveness is especially relevant to high density trunking where there is sufficient traffic to justify dual-station site diversity
Very high voltage latching relay
Relay consists of high voltage reed switch actuated by rotating permanent magnet mounted on stepper motor shaft, with actuation assembly isolated from high voltage circuit. Unit can be modified for use as double pole or double pole double throw latching relay and can be used in either air or vacuum
