The authors conducted a study of teachers' perceptions of the potential costs and benefits of involvement in school decision making. The teachers interviewed rated the potential costs of decision making involvement as low and the potential benefits as high. Nevertheless, many were hesitant to become involved because they saw little possibility that their involvement would actually make a difference.

Schmidt hammer (SH) R‐values are reported for surface clasts from numerically dated Holocene and Pleistocene fluvial terraces in the South Island of New Zealand. The R‐values are combined with previously obtained weathering rind, radiocarbon, terrestrial cosmogenic nuclide and luminescence terrace ages to derive SH R‐value chronofunctions for greywacke clasts from four distinct locations. Our results show that different weathering rates affect the form of the SH R‐value versus Age curve, however a fundamental dependency between the two remains constant over timescales ranging from 102 to 105 years. Power law scaling constants suggest changes in clast weathering rates are primarily affected by climatic (precipitation and temperature) and sedimentologic variables (source terrane petrology). Age uncertainties of ~22% of the surface age suggest that Schmidt hammer exposure‐age dating (SHD) is a reliable calibrated‐age dating technique for fluvial terraces.

This article examines the decisions made by one principal in her first year as a school turnaround specialist in a low-performing urban elementary school. Researchers focused on decisions related to the principal's three high-priority concerns: (1) elimination of an ineffective instructional program; (2) creation of a culture of teacher accountability; and (3) development of an effective reading program. Forty-nine decisions were identified and organized into five categories-performance, policy, program, process, and personnel decisions. The study concludes with a discussion of what principals need to know in order to make the kinds of decisions required of a 'turnaround' principal. -making, leader ship, principal, turnaround
