Manufacturing flexibility is often viewed as a strategic capability that enables firms to more effectively meet heterogeneous market demands arising, in part, from increased product proliferation. However, recent studies suggest that the operational challenges associated with meeting this objective may be heavily dependent not only upon a firm's internal modification, mix, and new product flexibilities, but also upon the flexibility of its inbound and outbound SUPPL.y chain partners. Drawing upon the theory of Complementarity, we examine if simultaneous utilization of both internal and external flexibilities does in fact create synergies that can improve a firm's delivery performance. Based on a sample of 158 U.S. manufacturing plants, we find that the extent to which performance enhancing synergies are generated is primarily dependent upon the type of internal flexibility that is paired with SUPPL.y chain flexibilities. Additionally, we find that when synergies do exist, external SUPPL.ier and logistics flexibilities generally tend to enhance the scope of flexible response, while internal flexibilities generally tend to enhance the achievability of a flexible response. Taken together, our findings suggest that the ability of firms to actually reap the synergistic benefits of an integrated system of SUPPL.y chain flexibility is much more complex and nuanced than previously believed or expected. © 2011 Elsevier B.V.

In this study, we develop a distance method for inferring unrooted species trees from a collection of unrooted gene trees. The species tree is estimated by the neighbor joining (NJ) tree built from a distance matrix in which the distance between two species is defined as the average number of internodes between two species across gene trees, that is, average gene-tree internode distance. The distance method is named NJst to distinguish it from the original NJ method. Under the coalescent model, we show that if gene trees are known or estimated correctly, the NJst method is statistically consistent in estimating unrooted species trees. The simulation results suggest that NJst and STAR (another coalescence-based method for inferring species trees) perform almost equally well in estimating topologies of species trees, whereas the Bayesian coalescence-based method, BEST, outperforms both NJst and STAR. Unlike BEST and STAR, the NJst method can take unrooted gene trees to infer species trees without using an outgroup. In addition, the NJst method can handle missing data and is thus useful in phylogenomic studies in which data sets often contain missing loci for some individuals. © 2011 The Author(s).

The notion of social capital or embeddedness has received increased attention in the field of supply chain management. However, although embeddedness has both a structural and a relational aspect, the structural has received more focus. In addition, circumstances that may affect the development of social capital, and the role and import of a focal firm's supply management function on aspects of social capital, remain unclear. This study draws on the social network perspective to explore factors associated with the relational embeddedness of social capital, and investigate the role of supply management on the process. Using empirical data collected from 204 U.S. manufacturing firms, an empirical framework is proposed and tested using structural equation modeling. The results of this study suggest a mechanism through which social capital affects firm performance, and indicate that the supply management function may contribute to sustainable competitive advantage. The study confirms that the relational embeddedness aspect of social capital should be treated as a critical antecedent to performance. It also highlights the potential role of the supply management function in developing social capital in dyadic network interactions. © 2009 Institute for Supply Management, Inc.™.

To survive and persist, an organism must acquire food, be able to reproduce, avoid being eaten, and prevent infection. However, each of these important traits is costly to maintain, which can lead to tradeoffs among the traits. That is, investment into one trait comes at a cost to another. The researchers propose an experimental approach examining simultaneous tradeoffs among three important biological traits (e.g., immunity, reproduction, and body movement) that will provide insight into the role of multi-trait tradeoffs in shaping how animals survive. Given that trait tradeoffs are influenced by the environment, these studies will occur in a range of manipulated environments that simulate the dynamics of environmental change in North America. Under stressful conditions, investment into one trait can take precedence over investment into another trait. However, if individuals encounter favorable environments (e.g., unlimited access to food), two traits, such as reproduction and immunity, may be maintained, suggesting that tradeoffs may be dependent upon food availability. The effects of food availability are often influenced by other environmental factors that may accompany reduced food availability (e.g., heat waves), and interactions between food availability and temperature may profoundly influence tradeoffs. This research will be the first to characterize the interplay between environmental variability and animal life history strategies using a network analysis approach. This approach has proven to be a powerful tool for studying diverse phenomena, such as social interactions, the structure of the Internet, and for optimizing solutions to engineering problems. Much of this research will be performed by students from under-represented minority groups, and it will be complemented by a science outreach program designed to educate community members (particularly K-8 students) on the importance of insect biology.

The proposed research will use a manipulative approach in a wing-dimorphic field cricket to examine tradeoffs among investment into three life history traits of widespread importance: reproduction, immune function, and locomotion. Resultant empirical data will be used for a network analysis approach to characterize dynamic relationships among these traits through the determination of several network metrics (e.g., connectivity, betweenness, and modularity). They will also examine linkages between the life history networks and a network of underlying physiological traits (e.g., antioxidant defense and metabolic rate). Further, they will use a network approach to determine the independent and interactive role of two universal environmental constraints (food availability and temperature) in multi-trait tradeoffs and trait-trait interactions. Thus, the proposed study will use an integrative approach to better understand how complex trait systems develop and are maintained. It will have impact on multiple biological disciplines, including ecological immunology, ecological physiology, network analyses, and life history evolution. The researchers will provide extensive research training to students, many of whom come from under-served minority groups representative of both the region and the student body at Georgia Southern University (GSU). To complement their research goals, they will develop an outreach program designed to educate young people about insects, an important taxonomic group. They will create a website and an accompanying outreach exhibition at the GSU Museum that provides information about local insects. They will also construct and disseminate an educational module designed to meet the State of Georgias Department of Education performance standards; this will contain structured activities, informational handouts, and live crickets that K-8 students can use to develop scientific literacy.

This Research Experiences for Teachers (RET) in Engineering and Computer Science Site, entitled Engaging Educators in Renewable EnerGY (ENERGY) at Georgia Southern University (GSU) aims to develop a diverse, competitive, and nationally engaged teacher workforce through activities and projects performed alongside graduate and undergraduate students, as well as faculty and industry advisors. The focus is on high-need rural areas in southeastern Georgia, in partner counties, that collectively are home to high populations of underrepresented minorities, economically disadvantaged and special needs students. Target participants include those who are from historically underrepresented groups in the STEM disciplines and those who teach in schools characterized by a high level of poverty and/or a high percentage of minority learners. ENERGY was specifically chosen as the research theme because it is a current national topic of direct interest to students and teachers, and it can be easily embedded in the high school STEM curriculum. In addition, there are regional industries involved in hands-on, cutting edge engineering research projects in energy-related fields. The research topics for the RET participants in ENERGY include: renewable and alternative energy (solar, wind, biofuels, thermoelectric), development of sensors and controls for energy applications, biologically-inspired wind turbines and solar collectors. As part of their engineering and scientific research projects, the teachers will be linked with real-world applications through collaborations with university and industry partners and will build upon long-term collaborative relationships between the participating school districts and the College of Engineering and Information Technology (CEIT) at GSU. This research experience will give participants the ability to immerse themselves into various engineering disciplines, expand their knowledge of engineering through research in renewable energy while giving them concrete hands-on examples and pedagogical methods of incorporating engineering into STEM curricula.

Over a three-year period the ENERGY RET Site will directly impact 30 STEM high school teachers, pre-service education majors, and community college faculty and approximately 4000 students. The goal of the ENERGY RET is to educate, engage, and inspire teachers to bring renewable energy to their classrooms through summer-term interdisciplinary STEM research experiences in the field of engineering and computer science. The educational objectives of this program are to: increase basic understanding of interdisciplinary concepts through hands-on learning, introduce STEM problem-solving skills and the ability to apply them in lectures and laboratories, and to increase interest in conducting STEM research. The program will develop the participants ability to collaborate and communicate effectively at both the interpersonal and presentation level all while part of a diverse team. RET participants, through fundamental energy-related research and transformational activities that are tied to industry, will leverage curricular approaches that allow them to transition this knowledge into highly inspirational STEM experiences for their students. The ENERGY participants, working with College of Education faculty, will develop activities and instructional practices that model and transfer their experience for integration of energy concepts into their classrooms during the academic year.
