The Changing Landscape of Leadership

Leading a campus is not what it used to be (nor is teaching a class, being a student, or raising a child for that matter). The increasing pace of societal and technological change provides an ever-evolving backdrop against which educational leaders view and conduct their work. Overlay a culture of accountability enacted amid budget cuts, surging enrollments, and shifting demographics, and the roles of school leaders become clouded with uncertainty, imbued with responsibility, and demanding increased personal commitment and professional and technical knowledge. One principal preparation student recently commented that her teaching colleagues routinely asked her, Why in the world do you want to do that? Upon reflection, it\u27s a valid question we should all answer

Current Realities for Public Schools

Administrators in today\u27s schools work in a constant state of flux; change is the norm. Congress\u27 recent reauthorization of the Elementary and Secondary Act, through the Every Student Succeeds Act (ESSA), provides a signal example. Just as many were beginning to fully understand and adjust to the implications of the now defunct No Child Left Behind (NCLB) Act, there\u27s a new set of rules to play by

Preparing Aspiring Superintendents to Lead School Improvement: Perceptions of Graduates for Program Development

Changes in the design and delivery of educational leadership preparation programs are advocated in order to meet the needs of leadership for 21st century schools (Byrd, 2001; Cox, 2002; McKerrow, 1998; Smylie & Bennett, 2005). The changing needs of the 21st century, coupled with accountability standards and more diverse populations of students within school districts, create challenges for leaders who are attempting to increase student achievement (Firestone & Shipps, 2005; Schlechty, 2008). Further, student performance demands have increased at the state and national level because of the No Child Left Behind Act (Wong & Nicotera, 2007). These standards have thus increased the emphasis of the administrator\u27s responsibility to positively impact student achievement (Taylor, 2001). With the graying of the profession and the need for exemplary school superintendents, the preparation of school superintendents who can successfully lead school improvement is vitally important (Lashway, 2006). According to the National Council for the Accreditation of Teacher Education (NCATE, 2002), university preparation programs should seek current leaders\u27 perspectives of critical content components and the processes to be used in the preparation of educational leaders who can lead school improvement practices and processes

Active Shooter Events: The Guardian Plan

The decision on how to protect the children and youth while at schools is a serious conversation with varying agreements on the best practices. Some feel that school personnel should not be trained nor expected to be able to react to an armed person while others believe that training of school personnel and allowing them to be armed will deter armed assailants in schools. Ultimately, each school board and district leadership need to choose an emergency safety plan that fits their community. The number of school shootings has brought emergency safety discussions to the forefront again. One school district, highlighted in this article, chose the implementation of a plan called the Guardian Plan

General practitioners' reasons for removing patients from their lists: postal survey in England and Wales

The removal of patients from doctors' lists causes con­ siderable public and political concern, with speculation that patients are removed for inappropriate, including financial, reasons. In 1999 the House of Commons Select Committee on Public Administration noted that little evidence was available on either the frequency of, or the reasons for, removal of patients. National statistics do not distinguish between patients removed after moving out of a practice area and those removed for other reasons. Two postal surveys have reported why general practitioners might, in general, remove patients, and one small study has described the reasons doctors give for particular removals. We therefore determined the current scale of, and doctors' reasons for, removal of patients from their lists in Eng­ land and Wales

Understanding and utilization of Thematic Mapper and other remotely sensed data for vegetation monitoring

The TM Tasseled Cap transformation, which provides both a 50% reduction in data volume with little or no loss of important information and spectral features with direct physical association, is presented and discussed. Using both simulated and actual TM data, some important characteristics of vegetation and soils in this feature space are described, as are the effects of solar elevation angle and atmospheric haze. A preliminary spectral haze diagnostic feature, based on only simulated data, is also examined. The characteristics of the TM thermal band are discussed, as is a demonstration of the use of TM data in energy balance studies. Some characteristics of AVHRR data are described, as are the sensitivities to scene content of several LANDSAT-MSS preprocessing techniques

Body of Knowledge (BOK) for Copper Wire Bonds

Copper wire bonds have replaced gold wire bonds in the majority of commercial semiconductor devices for the latest technology nodes. Although economics has been the driving mechanism to lower semiconductor packaging costs for a savings of about 20% by replacing gold wire bonds with copper, copper also has materials property advantages over gold. When compared to gold, copper has approximately: 25% lower electrical resistivity, 30% higher thermal conductivity, 75% higher tensile strength and 45% higher modulus of elasticity. Copper wire bonds on aluminum bond pads are also more mechanically robust over time and elevated temperature due to the slower intermetallic formation rate - approximately 1/100th that of the gold to aluminum intermetallic formation rate. However, there are significant tradeoffs with copper wire bonding - copper has twice the hardness of gold which results in a narrower bonding manufacturing process window and requires that the semiconductor companies design more mechanically rigid bonding pads to prevent cratering to both the bond pad and underlying chip structure. Furthermore, copper is significantly more prone to corrosion issues. The semiconductor packaging industry has responded to this corrosion concern by creating a palladium coated copper bonding wire, which is more corrosion resistant than pure copper bonding wire. Also, the selection of the device molding compound is critical because use of environmentally friendly green compounds can result in internal CTE (Coefficient of Thermal Expansion) mismatches with the copper wire bonds that can eventually lead to device failures during thermal cycling. Despite the difficult problems associated with the changeover to copper bonding wire, there are billions of copper wire bonded devices delivered annually to customers. It is noteworthy that Texas Instruments announced in October of 2014 that they are shipping microcircuits containing copper wire bonds for safety critical automotive applications. An evaluation of copper wire bond technology for applicability to spaceflight hardware may be warranted along with concurrently compiling a comprehensive understanding of the failure mechanisms involved with copper wire bonded semiconductor devices
