Key Elements of a State Master Plan in Higher Education

A master plan in higher education is developed to address the academic and workforce needs of a particular state. The master plan helps serve as the roadmap for implementation of proposed strategies to reach state goals in education and degree attainment. In Tennessee, Drive to 55 is a state-wide effort to increase the number of Tennesseans with a higher education credential to 55% by the year 2025. In an attempt to gain a deeper understanding of the key elements within state master plans, an independent review of ten state plans was conducted. The states involved in the analysis were Tennessee, Virginia, West Virginia, New York, Colorado, Arkansas, Nevada, Louisiana, Connecticut, and Massachusetts. The informal review revealed four key elements of state master plans in higher education: accessibility, affordability, accountability, and success. A consensus to reach underserved, underrepresented, or nontraditional students could be found among all ten states. Increasing accessibility to higher education can help abridge achievement gaps and eliminate disparities. Through responsible planning, management of resources, and assistance of those with demonstrated financial need, a quality higher education degree or credential that is affordable could be obtained. Accountability is measured in various ways by the ten states; however, clear expectations for performance are needed to ensure student success and positive institutional outcomes are experienced. A key element of success was noted to be college readiness and characteristics of students including determination and grit. Nine out of the ten states reviewed had some form of performance-based funding measures in place; providing incentives for institutions to help students successfully complete degree program

A Study of the "toss Factor" in the Impact Testing of Cermets by the Izod Pendulum Test

The test method presented shows that the "toss energy" contributed by the apparatus for brittle materials is negligible. The total toss energy is considered to consist of two components. (a) recovered stored elastic energy and (b) kinetic energy contributed directly by the apparatus. The results were verified by high-speed motion pictures of the test in operation. From these photographs, velocities of tossed specimens were obtained and toss energy computed. In addition, impact energies of some titanium carbide base cermets and high-temperature alloys, as measured by the low-capacity Izod pendulum test, compare well with impact energies measured by the NACA drop test

A Quality-Preserving Increase in Four-Year College Attendance

We use the National Longitudinal Study of the High School Class of 1972 and the Education Longitudinal Study of 2002 data sets to evaluate changes in the college matching process. Rising attendance rates at 4-year institutions have not decreased average preparedness of college goers or of college graduates, and further attendance gains are possible before diminishing returns set in. We use multinomial logic models to demonstrate that measures of likely success (grade point average) became more predictive of college attendance over time, while other student characteristics such as race and parents’ education became less predictive. Our evidence suggests that schools have become better at sorting while students have efficiently responded to changes in the return to higher education

Potential use of algae for heavy metal bioremediation, a critical review

Algae have several industrial applications that can lower the cost of biofuel co24 production. Among these co-production applications, environmental and wastewater bioremediation are increasingly important. Heavy metal pollution and its implications for public health and the environment have led to increased interest in developing environmental biotechnology approaches. We review the potential for algal biosorption and/or neutralization of the toxic effects of heavy metal ions, primarily focusing on their cellular structure, pretreatment, modification, as well as potential application of genetic engineering in biosorption performance. We evaluate pretreatment, immobilization, and factors affecting biosorption capacity, such as initial metal ion concentration, biomass concentration, initial pH, time, temperature, and interference of multi metal ions and introduce molecular tools to develop engineered algal strains with higher biosorption capacity and selectivity. We conclude that consideration of these parameters can lead to the development of low-cost micro and macroalgae cultivation with high bioremediation potential

Bed II Sequence Stratigraphic context of EF-HR and HWK EE archaeological sites, and the Oldowan/Acheulean succession at Olduvai Gorge, Tanzania

Archaeological excavations at EF-HR and HWK EE allow reassessment of Bed II stratigraphy within the Junction Area and eastern Olduvai Gorge. Application of Sequence Stratigraphic methods provides a time-stratigraphic framework enabling correlation of sedimentary units across facies boundaries, applicable even in those areas where conventional timelines, such as tephrostratigraphic markers, are absent, eroded, or reworked. Sequence Stratigraphically, Bed II subdivides into five major Sequences 1 to 5, all floored by major disconformities that incise deeply into the underlying succession, proving that simple "layer cake" stratigraphy is inappropriate. Previous establishment of the Lemuta Member has invalidated the use of Tuff IIA as the boundary between Lower and Middle Bed II, now redefined at the disconformity between Sequences 2 and 3, a lithostratigraphic contact underlying the succession containing the Lower, Middle, and Upper Augitic Sandstones. HWK EE site records Oldowan technology in the Lower Augitic Sandstone at the base of Sequence 3, within Middle Bed II. We suggest placement of recently reported Acheulean levels at FLK W within the Middle Augitic Sandstone, thus emphasizing that handaxes are yet to be found in earlier stratigraphic units of the Olduvai sequence. This would place a boundary between the Oldowan and Acheulean technologies at Olduvai in the Tuff IIB zone or earliest Middle Augitic Sandstone. A major disconformity between Sequences 3 and 4 at and near EF-HR cuts through the level of Tuff IIC, placing the main Acheulean EF-HR assemblage at the base of Sequence 4, within Upper rather than Middle Bed II. Sequence stratigraphic methods also yield a more highly resolved Bed II stratigraphic framework. Backwall and sidewall surveying of archaeological trenches at EF-HR and HWK EE permits definition of “Lake-parasequences” nested within the major Sequences that record downcutting of disconformities associated with lake regression, then sedimentation associated with lake transgression, capped finally by another erosional disconformity or hiatal paraconformity caused by the next lake withdrawal. On a relative time-scale rather than a vertical metre scale, the resulting Wheeler diagram framework provides a basis for recognizing time-equivalent depositional episodes and the position of time gaps at various scales. Relative timing of archaeological assemblage levels can then be differentiated at a millennial scale within this framework

Magnetic flux jumps in textured Bi2Sr2CaCu2O(8+d)

Magnetic flux jumps in textured Bi2Sr2CaCu2O(8+d) have been studied by means of magnetization measurements in the temperature range between 1.95 K and Tc, in an external magnetic field up to 9 T. Flux jumps were found in the temperature range 1.95 K - 6 K, with the external magnetic field parallel to the c axis of the investigated sample. The effect of sample history on magnetic flux jumping was studied and it was found to be well accounted for by the available theoretical models. The magnetic field sweep rate strongly influences the flux jumping and this effect was interpreted in terms of the influence of both flux creep and the thermal environment of the sample. Strong flux creep was found in the temperature and magnetic field range where flux jumps occur suggesting a relationship between the two. The heat exchange conditions between the sample and the experimental environment also influence the flux jumping behavior. Both these effects stabilize the sample against flux instabilities, and this stabilizing effect increases with decreasing magnetic field sweep rate. Demagnetizing effects are also shown to have a significant influence on flux jumping.Comment: 10 pages, 6 figures, RevTeX4, submitted to Phys. Rev.

Critical elements in implementing fundamental change in public environmental policy: Western Australia’s mine closure and rehabilitation securities reform

Development of public policy is a key role of government. Following the framework for Australian governments to uphold when developing public policy alone will not guarantee good policy development. This research critically explores the policy development process of the Department of Mines and Petroleum in Western Australia for mine closure and rehabilitation securities reform, where significant costs for mining companies, and large environmental and community legacies were at stake. Fundamental change from use of individual bonds to a central Mining Rehabilitation Fund resulted; offering financial advantage for mining companies and government alike, and a mechanism for rehabilitation of historically abandoned mines. Critical elements in the policy development process were: (1) openness in clearly articulating the policy problem at the outset, (2) retaining focus on the policy scope relevant to the jurisdictional level, (3) use of trusted experts especially for contentious aspects of the reform agenda, (4) commitment to stakeholder engagement throughout, and (5) acknowledging and managing uncertainties through transparent and consultative data gathering processes. Attention to these matters enabled an innovative and effective mine closure and rehabilitation policy solution to be implemented by the Government of Western Australia that is unique in Australia, and perhaps the world

Absence of Edge Localized Moments in the Doped Spin-Peierls System CuGe1−x_{1-x}Six_{x}O3_3

We report the observation of nuclear quadrupole resonance (NQR) of Cu from the sites near the doping center in the spin-Peierls system CuGe$_{1-x}$Si$_{x}$O$_3$. The signal appears as the satellites in the Cu NQR spectrum, and has a suppressed nuclear spin-lattice relaxation rate indicative of a singlet correlation rather than an enhanced magnetic correlation near the doping center. Signal loss of Cu nuclei with no neighboring Si is also observed. We conclude from these observations that the doping-induced moments are not in the vicinity of the doping center but rather away from it.Comment: 4 pages, 4 figures, accepted for publication in Phys.
