Contribution Of Lianas To Plant Area Index And Canopy Structure In A Panamanian Forest, M. Elizabeth Rodríguez-Ronderos, Gil Bohrer, Arturo Sanchez-Azofeifa, Jennifer S. Powers, Stefan A. Schnitzer Dec 2016

Contribution Of Lianas To Plant Area Index And Canopy Structure In A Panamanian Forest, M. Elizabeth Rodríguez-Ronderos, Gil Bohrer, Arturo Sanchez-Azofeifa, Jennifer S. Powers, Stefan A. Schnitzer

Lianas are an important component of tropical forests, where they reduce tree growth, fecundity, and survival. Competition for light from lianas may be intense; however, the amount of light that lianas intercept is poorly understood. We used a large-scale liana-removal experiment to quantify light interception by lianas in a Panamanian secondary forest. We measured the change in plant area index (PAI) and forest structure before and after cutting lianas (for 4 yr) in eight 80 m × 80 m plots and eight control plots (16 plots total). We used ground-based LiDAR to measure the 3-dimensional canopy structure before cutting lianas, …

Neighborhood Characteristics Contribute To Urban Alcohol Availability: Accounting For Race/Ethnicity And Social Disorganization, Aleksandra J. Snowden Oct 2016

Neighborhood Characteristics Contribute To Urban Alcohol Availability: Accounting For Race/Ethnicity And Social Disorganization, Aleksandra J. Snowden

Social and Cultural Sciences Faculty Research and Publications

This study examined the role that race/ethnicity and social disorganization play in alcohol availability in Milwaukee, Wisconsin, census block groups. This study estimated negative binomial regression models to examine separately the relationship between neighborhood racial/ethnic composition and social disorganization levels for (1) total, (2) on-premise, and (3) off-premise alcohol outlets. Results of this study suggest that proportion Hispanic was positively associated with total and with off-premise alcohol outlets. Second, proportion African American was negatively associated with on-premise alcohol outlets and positively associated with off-premise alcohol outlets. Proportion Asian was not associated with total, on-premise, or off-premise alcohol outlets. However, the …

Examining The Role Of The Catholic Environment In Students’ Search For Meaning, Jody Jessup-Anger, Jonathan C. Dooley, Rachel Leih, Elizabeth Mueller, Kathleen Lis Dean Jul 2016

Examining The Role Of The Catholic Environment In Students’ Search For Meaning, Jody Jessup-Anger, Jonathan C. Dooley, Rachel Leih, Elizabeth Mueller, Kathleen Lis Dean

College of Education Faculty Research and Publications

Emerging research illustrates that undergraduate students are searching for meaning in their lives, yet postsecondary institutions generally do little to support them in exploring such issues (Astin et al., 2005b). We speculated that religiously affiliated institutions might offer guidance on supporting students’ spiritual development, and thus examined students in the context of Catholic postsecondary environments, focusing on whether the students’ religious affiliations and perceptions of their institution as supporting their spiritual development affected their search for meaning. Further, we examined the aspects of the environment that strengthened students’ perceptions of their college environment as closely aligned with the Catholic mission, …

Alcohol Outlet Density And Intimate Partner Violence In A Nonmetropolitan College Town: Accounting For Neighborhood Characteristics And Alcohol Outlet Types, Aleksandra J. Snowden Jan 2016

Alcohol Outlet Density And Intimate Partner Violence In A Nonmetropolitan College Town: Accounting For Neighborhood Characteristics And Alcohol Outlet Types, Aleksandra J. Snowden

Social and Cultural Sciences Faculty Research and Publications

There is a growing evidence of an ecological association between alcohol outlet density and intimate partner violence. It is reasonable to assume, however, that not all types of alcohol outlets contribute equally to criminal behavior, and to date, most ecological studies have been of large urban cities. Using Bloomington, Indiana, block groups as units of analysis and controlling for several structural characteristics associated with violence rates, I estimated spatially lagged regression models to determine if the variation in alcohol outlet density, including total outlets and disaggregating by on- and off-premise outlets, is related to intimate partner violence density. Results suggested …
