In Rwanda, farmers’ traditional farming systems based on intercropping and varietal mixtures are designed to meet a variety of livelihood objectives and withstand risks associated with fluctuation in market and agro-climatic conditions. However, these mixed systems have been disappearing since 2008 when government mandated intensification strategies. In(More)
Studied the reliability of the Washington University Sentence Completion Test by giving 51 9th graders and 26 college students the test twice, a week apart. For 9th graders the design included a test-retest group and two groups given half of the test at each session. Although test-retest correlations were high for the 9th graders, retest scores dropped(More)

Perennial crops have numerous ecological and agronomic advantages over their annual counterparts. We estimate discrete choice models to evaluate farmers' preferences for perennial attributes of pigeon pea intercropped with maize in central and southern Malawi. Pigeon pea is a nitrogen-fixing leguminous crop, which has the potential to ameliorate soil(More)
PURPOSE This study was designed to help dental hygiene educators identify predictors of early instrumentation achievement among preclinical students. Studies from other disciplines suggest that underlying abilities play a significant role in early skill development and that additional factors contribute to later skill development. Previous studies in the(More)
Quantitative and qualitative data from a group of 12 novice hoophouse farmers over a 3-year period in Michigan were analyzed to better understand factors associated with profitable use of these structures. There was wide variation in labor inputs and effective wages. We used regression analysis and semistructured interviews to better understand the(More)
Adoption rates of leguminous crops remain low in sub-Saharan Africa despite their potential role in improving nutrition, soil health, and food security. In this study we explored Malawian farmers’ perceptions of various legume attributes and assessed how these perceptions affected allocation of land to legume crops using a logit link model. We found high(More)
Twelve hand measurements were made on 45 first-year dental hygiene students within one week of their entering a dental hygiene program. Multiple regression was performed, using three clinical examinations (use of periodontal probe, use of 3-A explorer, and use of Gracey curets) as dependent variables, to assess whether or not hand measurements predicted(More)
