Emergent achievement segregation in freshmenlearning community networks

A common assumption about Freshmen Learning Communities (FLCs) is that academic relationships contribute to students’ success. This study investigates how students inlearning communities connect with fellow students for friendship and academic support. Longitudinal social network data across the first year, collected from 95 Dutch students in eight FLCs, measure both social and academic relational choices within and beyond the FLCs. Using stochastic actor-based models, the study tests two competing hypotheses. The alignment hypothesis states that students connect with their similar-achieving friends for both academic and social support, leading to an alignment of both types of networks over time. In contrast, the duality hypothesis states dissimilarity between academic support networks and friendship networks: students should connect with better-achieving fellow students for academic support and to more similar peers for friendship. The data support the alignment hypothesis but not the duality hypothesis; in addition, they show evidence of achievement segregation in FLCs: the higher the students’ achievement level, the more they connect with other students for both academic support and friendship, relating in particular to peers with a similarly high achievement level. The results suggest that lower-achieving students are excluded from the support provided by higher achieving students and instead ask similar lower achievers for support. They thus cannot benefit optimally from the academic integration FLC offer. The article concludes with recommendations of how to support students in an FLC so that they can reach optimal achievement potential

The Contribution of Management Control Systems to Environmental Capabilities

International audienceA growing number of companies are implementing proactive environmental strategies with the objective of gaining competitive advantage through an enhanced reputation, the reduction of production costs and a first-mover advantage in the green product market. Yet according to the natural-resource-based view, the development and maintenance of unique and valuable environmental capabilities are the central elements allowing companies to gain financial benefit from their proactive environmental strategy. In this context, management control systems can contribute to the development of environmental capabilities by focusing attention on strategic priorities and stimulating dialogue. Through a single case study, and building on Simons' (1995) four levers of control, we propose a conceptual framework of management control levers that show how companies can enhance (1) stakeholder integration capability through the joint use of belief, boundary and diagnostic control systems; (2) shared vision capability through the joint use of the belief and boundary systems; (3) organizational learning capability through the use of interactive control systems and to a lesser extent diagnostic control systems; and (4) continuous innovation capability through the use of interactive control systems, belief systems and to a lesser extent diagnostic control systems
