Objectives. To evaluate the effectiveness of an evidence-based, parent-centered intervention, Familias Unidas, delivered by nonresearch personnel, in preventing substance use (alcohol, illicit drugs) and sex without a condom among Hispanic adolescents. Methods. A randomized controlled trial (n = 746) evaluated the effectiveness of Familias Unidas among Hispanic eighth graders (age range = 12–16 years), relative to prevention as usual, within a public school system. School personnel, including social workers and mental health counselors, were trained to deliver the evidence-based intervention. Participant recruitment, intervention delivery, and follow-up ran from September 2010 through June 2014 in Miami–Dade County, Florida. Results. Familias Unidas was effective in preventing drug use from increasing and prevented greater increases in sex without a condom 30 months after baseline, relative to prevention as usual. Familias Unidas also had a positive impact on family functioning and parental monitoring of peers at 6 months after baseline. Conclusions. This study demonstrated the effectiveness of a parent-centered preventive intervention program in preventing risky behaviors among Hispanic youths. Findings highlight the feasibility of training nonresearch personnel on effectively delivering a manualized intervention in a real-world setting.
Are Basic School Head Teachers Transformational Leaders? Views of Teachers
Authors: Asare Kwame Bediako 
Published: February 2017

Transformational leadership practice is associated with improved school functioning and quality education delivery through teacher commitment and willingness to exceed targets or educational benchmarks (Balyer, 2012; Nedelcu, 2013). The establishment of the Leadership for Learning (LFL) program in Ghana in 2009 aimed at improving the effectiveness of basic school head teachers to better lead schools to promote student learning. In this study, the perceptions of basic school teachers as to the transformational leadership conduct of head teachers who had received training under the LFL model were collected and reviewed. The purpose of this qualitative inquiry was to determine from teachers’ perceptions how the conduct of head teachers related to transformational leadership. From the study results, the findings indicated that while teachers largely perceived their head teachers as transformational leaders, more than the influence of head teachers is required to motivate teachers to give of themselves to improve education outcomes. Recommendations and implications of the study for practice and research were considered.
Shape of Time Domain Reflectometry Signals during the Passing of Wetting Fronts
Authors: Germann Peter F. 
Published: February 2017

Core Ideas
Precise wetting front arrival times can be determined from local TDR readings.
Wetting shock fronts due to preferential flow are sharp.
This approach uses the control volume with two‐rod TDR probes as the longitudinal axis.
Estimates of preferential flow rates follow from this approach.
Viscous flow theory expects sharp wetting shock fronts during infiltration in permeable media, but time domain reflectometry (TDR) measurements, using horizontally installed two‐rod probes, reveal concave and convex increases at the early and late stages during the passing of the front, i.e., the TDR signals are S‐shaped. Wetting front dispersal was initially considered as the cause, due to variations in the flow path lengths at the profile scale. However, later studies favored processes that are closer to the scale of the TDR control volume. In this study, an approach was developed that quantifies the shape of TDR signals exclusively with local features. It improves the determination of the arrival time of a wetting shock front at the depth of a TDR probe, and it ultimately supports the notion of sharp wetting shock fronts at the scale of the probe's length that evolve during preferential infiltration.
