Comprehensive testing of a defense systems communications satellite

The system level testing of the defense satellite communications system (DSCS) 3 program is reviewed. Concentration is on the results of the systems tests of the DSCS 3 development test model (DTM). The DSCS 3DTM consisted of engineering components interconnected in an open bench layout. The DTM tests were performed to demonstrate satellite electrical performance characteristics and to uncover design deficiencies and interface problems. The availability of the DTM test results prior to the fabrication of the flight model hardware permited the incorporation of necessary design changes with a minimum impact on program costs and schedules

The Preparedness Of Elementary Music Teachers To Include Students With Challenging Behavior In Their Classrooms

Students with disabilities, some with emotional and behavior disorders, are included in almost all elementary music classes. Students with emotional behavior disorders are one of the greatest challenges for teachers. To be effective, teachers must develop strategies and inclusive practices specifically geared towards intervention. With the quantity of students served and only limited class time with students, the music teacher is often unaware of the unique needs of specific special learners. Music teacher preparation has been inadequate in training teachers for inclusion. Elementary music educators rarely have outside support to deal with classroom challenges as they serve students with disabilities and at-risk students. Music teacher training is focused on content, not behavior management. This study examined the perceptions of randomly selected elementary music educators who were members of MENC: The National Association for Music Education regarding their preparedness to effectively manage five areas of severe behavior often exhibited by students with emotional behavior disorders: withdrawal, impulsivity, argumentative behavior, aggression towards peers, and aggression towards the teacher. The researcher devised a 39 item online survey instrument based on supporting literature. The survey was given to randomly selected participants. Two hundred sixty-nine elementary music educators from across the United States completed the survey providing information on incidence frequency, preparedness, training in behavior management, and the amount of behavior support available. Elementary music teachers felt prepared to handle impulsivity (58.2%), and argumentative behavior (55.7%). They were not prepared for withdrawal (50.8%), aggression towards peers (50.9%), and least prepared to handle aggression towards the teacher (58.1%).Over 94% of the music teachers had adult assistance less than 25% of the time and 45.9% never had adult assistance with included classes. More than 74% of the teachers indicated that they have adult assistance with self-contained special education classes less than 25% of the time and 35.7% never having adult assistance with those classes. Forty-six point two percent of the music teachers had no behavior specialist available or were unaware if one was available. Only 3.7% of the respondents felt they had all the support they needed. Thirty-six point one percent of the music teachers had no crisis plan in case of an eruption of severe behavior in their classes

The deduction of repairs to property in terms of section 11(d) of the Income Tax Act 58 of 1962

As the burden borne by the South African taxpayer seems to increase yearly, the prudent taxpayer must embrace the various deductions available to him or her in terms of the Act . In order to do so the taxpayer must understand the ambit of each deduction so that he or she may plan accordingly. A deduction that has for many years granted relief to the weary taxpayer is that contained in Section 1 l(d)

Bank Street and Teach for America: Process and Preparation

In this paper I analyze the goals and practices of education that are implied in the mission statements and literature of Bank Street College of Education (Bank Street) and Teach for America (TFA). I noticed and struggled to understand the tension between the mission statements of the two organizations that I was a part of during my master\u27s program. While analyzing the readings and my experiences, I began to see differences between these two organizations\u27 theories and beliefs about child development. I considered how my experiences with children supported or refuted these beliefs. From Bank Street, I recognized many beliefs about child development that confirmed ideas and feelings that I have passionately considered in my own education and in my experience as a teacher. From TFA, I recognized beliefs about child development that have been sources of frustration. In summary, I\u27ve found that my experience at Bank Street has helped me to see education, like Dewey (1897) saw it, as a process of living and not a preparation for future living

Sex-specific Habitat Use and Responses to Fragmentation in an Endemic Chameleon Fauna

Chameleons are an understudied taxon facing many threats, including collection for the international pet trade and habitat loss and fragmentation. A recent field study reports a highly female-biased sex ratio in the Eastern Arc Endemic Usambara three horned chameleon, Trioceros deremensis, a large, sexually dimorphic species. This species is collected for the pet trade, and local collectors report males bring a higher price because only this sex has horns. Thus, sex ratios may vary due to differential rates of survival or harvesting. Alternatively, they may simply appear to be skewed if differences in habitat use biases detection of the sexes. Another threat facing chameleons is that of habitat loss and fragmentation. Despite enormous amounts of research, the factors of fragmentation that different species respond to is still under debate. Understanding these responses is important for current mitigation efforts as well as predicting how species will respond to future habitat alteration and climate change. My study suggests that differences in survival and detection may explain much of the observed seasonal sex skew in adult T. deremensis. Within fragmented habitat chameleons consistently responded more to edge effects and vegetative characteristics associated with fragmentation than to area or isolation effects. This may bode poorly for chameleon populations in the coming decades as climate change further alters vegetative communities and exacerbates edge effects

Shaping Public Programs through Medicare, Medicaid, and SCHIP Waivers: The Fundamentals

This background paper examines the use of research, demonstration, and program waiver authorities to test new approaches to the delivery of and payment for health care services in federally financed health coverage programs such as Medicare, Medicaid, and the State Children’s Health Insurance Program. The paper also looks at the mechanics of waivers as well as their history and political context in shaping public programs. In addition, it explores the ways the changing state-federal relationship and the ever-growing demand for state flexibility have driven waiver policy

Crisis Communication in the Public Sector: Influences on Stakeholders’ Experience of Psychological Effects as U.S.-Russia Tensions Rise

As war in Ukraine rages on and the U.S.-Russia relationship becomes increasingly hostile, the need to better understand public sector communication in times of international crisis is once again rising. For years, the public and private sectors have been treated largely the same in crisis communication research and practice. In the context of international crisis, specifically rising tensions between the U.S. and Russia, this study looks at where these differences lie and what that might mean for future research and practice. In contribution to this broader topic, this study looks at the influence of domestic stakeholders’ perceptions of the Biden Administration’s adapting information about the crisis on their experience of psychological effects, anger and anxiety. It was also hypothesized that involvement and political ideology would have moderating effects on this relationship. Through a survey of 644 U.S. citizens and residents, adapting information was shown to have a strong positive correlation with psychological effects. The moderation was insignificant; however, both political ideology and involvement correlated significantly to psychological effects. Findings support treating public and private sector organizations differently in research and practice. Further research is suggested for defining more differences and determining best practices for public sector crisis communication

Rebalancing Long-Term Care: The Role of the Medicaid HCBS Waiver Program

This paper reviews the history and background of the Medicaid home and community-based services (HCBS) waiver program. It describes the eligibility, benefits, and financing structure, as well as the trends in program expenditures over time. The paper considers the contribution of the HCBS waiver program toward improving access to community-based care for Medicaid beneficiaries who are elderly and disabled and discusses the barriers that remain. This paper also summarizes the provisions included in the recently enacted Deficit Reduction Act of 2005 that may further expand Medicaid HCBS and considers how it may continue the process of redefining the concept of long-term care
