Patterns in Group Involvement Experiences During College: Identifying a Taxonomy

This study explored whether latent phenomena could be identified to classify students based on their patterns of involvement in cocurricular group experiences. The sample was comprised of 11,209 seniors from 50 institutions. A total of 4 latent factors were identified and students were classified into one of 8 latent classes. Findings offer new analytic and conceptual approaches for use in college impact research as well as a useful heuristic tool to assist student affairs professionals in designing and targeting educational interventions

Exploring Relationships Between Fraternity and Sorority Membership and Socially Responsible Leadership

Membership in social fraternities and sororities provides a powerful platform for developing college students’ capacity for leadership. The existing knowledge regarding the extent to which it fulfills this goal, however, is relatively sparse. Much of the research on college student leadership relies on definitions that are inconsistent with contemporary conceptualizations. This study addresses this gap by looking at the leadership development of fraternity and sorority members using data from a national study grounded in the social change model. Results indicated fraternity and sorority members scored highest on the leadership value of commitment and lowest on the capacity to navigate change. Findings also revealed statistically significant differences across seven of eight leadership measures based on membership in sororities versus fraternities

Advanced turboprop technology development

The efficiency of high-speed turboprop propulsion systems is considered with emphasis on fuel savings. Specific topics discussed include: (1) high efficiency and low noise of propeller design; (2) fuselage noise attenuation; (3) propeller and gear box maintenance; and (4) engine-airframe integration

Research in development: the approach of AAS

The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is pursuing a Research in Development approach that emphasizes the importance of embedding research in the development context. Reflecting this emphasis the six elements of this approach are a commitment to people and place, participatory action research, gender transformative research, learning and networking, partnerships, and capacity building. It is through the careful pursuit of these six elements that we believe that the program will achieve the development outcomes we aspire to, and do so at scale

Investing in Africa: the WorldFish Center's African strategy in summary

Across much of Africa, freshwater and coastal fisheries provide an important source of food and livelihood for many millions of people. In addition, the aquaculture potential of the continent has only recently begun to be developed. To help sustain these capture fisheries, support the emergence of aquaculture and foster the contribution of both to sustainable livelihoods and improved food security, the WorldFish Center is increasing its investment in Africa. The framework for this investment is provided by a new Strategy for Africa and West Asia 2002-2006 that identifies priorities for the Center’s work in rivers and floodplains, lakes and reservoirs, coastal fisheries, aquaculture, policy research and capacity building. The present article summarizes the issues being addressed by the Center and describes initial research priorities

Ground Heave Due to Pile Driving

The factors which influence ground heave due to pile driving outside the construction site are discussed. Elevation survey data are presented for nine case studies in the Boston area where the subsoil conditions consist of an insensitive clay deposit in the range of 60 to 110 feet thick. Curves of heave vs. normalized distance exhibit a trend of increasing heave with increased volumetric displacement ratio. Patterns of ground heave typically occur as radially shaped contours decreasing in magnitude away from pile driving. Building and ground movements observed several years after completion of pile driving indicate that the heave is temporary, and is followed by a net settlement. Eight factors which influence heave due to pile driving are briefly discussed. Pile driving can be designed to minimize or prevent heave by properly planning the methods and sequence of pile installation
