A Study of the Impact of the Alternative Intervention Program on Improving Student Achievement, Attendance, and Discipline
This mixed methods study sought to examine student perceptions of the impact of an alternative intervention program (AIP), and provide a framework meant to inspire programs in other locations. Focusing on attendance, discipline, and academic achievement data, this study examined what factors motivate successful alternative education students to succeed upon their return to the comprehensive setting, and identify support factors that foster resiliency. Qualitative data were collected through three focus groups of students who were either new to the program, enrolled in the program for at least a nine-week period, and students who successfully completed a nine-week placement. Six adult students who completed the program and received a high school diploma were in-depth interview participants. Quantitative data were collected using student records. Results indicated differences in the students’ perception of grades earned and the actual grades received. Students were able to maintain their attendance, grades, and discipline during the alternative program enrollment, but scored lower in English and Mathematics after leaving the program than they did prior to attending the program. The fast pace and rigor of a standards-based curriculum in a comprehensive setting proved challenging for students in need of a caring, nurturing environment that offered individualized instruction. Students overwhelmingly attribute their success in the alternative program to a caring staff, and flexible scheduling within a structured environment. This study revealed the need for a more structured process to transition students from the alternative to comprehensive settings. Students could literally be in the alternative setting today and in the comprehensive setting tomorrow, with very little support or guidance. This led to repeated disciplinary offenses and for some students, their return to the alternative setting

The Role Modelling and Farming Systems Research Can Play in Redesigning Grazing Systems for Improved Productivity and Environmental Sustainability
Achieving production and natural resource outcomes from farming systems is critical with growing demand for livestock products, increasing pressure on land and water resources and the desire of farmers to improve profit and standard of living. In many countries this brings to the fore a number of policy dilemmas and conflicts in terms of pastoral household livelihood, regional economic growth and development, as well as natural resource management. By using two case studies; (1) Temperate Grasslands in Southern Australia (EverGraze project); and (2) Western Grasslands in North West China (ACIAR project), this paper considers how farming systems can be redesigned for production and environmental outcomes using modelling and farming systems research. Farming systems, as well as the regions and economies in which they operate, are complex and under constant change. The use of models combined with good science, relevant data and regional validation is essential to examine alternative systems that are better suited to changed operating conditions. Bio-economic modelling helps to understand trade-offs between production and enterprise performance and environmental sustainability over time and, most importantly, where multiple benefits from farming systems are possible. We contend that it is possible to redesign farming systems with both enterprise and environmental sustainability in mind. However the approach used to design and test alternative farming systems is important in an era of declining research resources and increasing complexity

Single electron Sensitive Readout (SiSeRO) X-ray detectors: Technological progress and characterization
Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge
detector output stage for charge-coupled device (CCD) image sensors. Developed
at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with a
depleted internal gate beneath the transistor channel. The transistor
source-drain current is modulated by the transfer of charge into the internal
gate. At Stanford, we have developed a readout module based on the drain
current of the on-chip transistor to characterize the device. Characterization
was performed for a number of prototype sensors with different device
architectures, e.g. location of the internal gate, MOSFET polysilicon gate
structure, and location of the trough in the internal gate with respect to the
source and drain of the MOSFET (the trough is introduced to confine the charge
in the internal gate). Using a buried-channel SiSeRO, we have achieved a
charge/current conversion gain of >700 pA per electron, an equivalent noise
charge (ENC) of around 6 electrons root mean square (RMS), and a full width
half maximum (FWHM) of approximately 140 eV at 5.9 keV at a readout speed of
625 Kpixel/s. In this paper, we discuss the SiSeRO working principle, the
readout module developed at Stanford, and the characterization test results of
the SiSeRO prototypes. We also discuss the potential to implement Repetitive
Non-Destructive Readout (RNDR) with these devices and the preliminary results
which can in principle yield sub-electron ENC performance. Additional
measurements and detailed device simulations will be essential to mature the
SiSeRO technology. However, this new device class presents an exciting
technology for next generation astronomical X-ray telescopes requiring fast,
low-noise, radiation hard megapixel imagers with moderate spectroscopic
resolution.Comment: To appear in SPIE Proceedings of Astronomical Telescopes +
