Thermochemistry of oxygen atom transfer from Cp*ReO3

The reaction enthalpy for O atom transfer from Cp*ReO3 to PPh(3) in toluene solution is measured to be -28.4 +/- 0.3 kcal/mol and -28.0 +/- 0.6 kcal/mol in THF solution. This allows the strength of the Re=O bond in Cp*ReO3 (in solution) to be estimated at 116.8 +/- 1.2 kcal/mol

Factors and Measures of Business Process Modelling: Model Building Through a Multiple Case Study

Business process modelling has gained widespread acceptance as a valuable design and management technique for a variety of purposes. While there has been much research on process modelling techniques and corresponding tools, there has been little empirical research into the success factors of effective process modelling, and the post hoc evaluation of process modelling success. This paper reports on the first attempt to identify process modelling success factors and measures, as empirically evidenced in case studies of nine process modelling projects in three leading Australian organizations

A group-randomized controlled trial for health promotion in Girl Scouts: healthier troops in a SNAP (Scouting Nutrition & Activity Program)

Background: Girl Scouting may offer a viable channel for health promotion and obesity prevention programs. This study evaluated the effectiveness of an intervention program delivered through Girl Scout Junior troops that was designed to foster healthful troop meeting environments and increase obesity prevention behaviors at home. Methods: Seven Girl Scout troops were randomized to intervention (n = 3, with 34 girls) or standard-care control (n = 4, with 42 girls) conditions. Girls ranged in age from 9 to 13 years (mean 10.5 years). Intervention troop leaders were trained to implement policies promoting physical activity (PA) and healthful eating opportunities at troop meetings, and to implement a curriculum promoting obesity-prevention behaviors at home. The primary outcome variable was child body mass index (BMI) z-score. Secondary outcomes included accelerometer-assessed PA levels in troop meetings, direct observations of snack offerings, time spent in physically active meeting content, and leader encouragement of PA and healthful eating. Results: The intervention was delivered with good fidelity, and intervention troops provided greater opportunities for healthful eating and PA (x2 = 210.8, p < .001), relative to control troops. In troop meetings, intervention troop leaders promoted PA (x2 = 23.46, p < .001) and healthful eating (x2 = 18.14, p < .001) more frequently, and discouraged healthful eating and PA less frequently (x2 = 9.63, p = .002) compared to control troop leaders. Most effects of the intervention on individual-level variables of girls and parents were not significantly different from the control condition, including the primary outcome of child BMI z-score (F1, 5 = 0.42, p = .544), parent BMI (F1, 5 = 1.58, p = .264), and related behavioral variables. The notable exception was for objectively assessed troop PA, wherein girls in intervention troops accumulated significantly less sedentary (x2 = 6.3, p = .011), significantly more moderate (x2 = 8.2, p = .004), and more moderate-to-vigorous physical activity, (x2 = 18.4, p < .001), than girls in control troops. Conclusions: Implementing a health promotion curriculum and supporting policies to provide more healthful environments in Girl Scout troop meetings appears feasible on a broader scale. Additional work is needed to bridge health promotion from such settings to other environments if lasting individual-level behavior change and obesity prevention remain targeted outcomes.
