Putting theory into practice: The creation of REALs in the context of today's universities

Rich Environments for Active Learning (REALs), as described by R. Scott Grabinger and Joanna Dunlap, are comprehensive educational systems based on constructivist principles that present an intellectual and practical challenge to university lecturers. As teachers and researchers, academics are concerned with improving the learning potential of teaching strategies and, to this end, the theory of the REAL provides inspiration and ideas based on sound theoretical principles. Yet in the context of the current pressured climate, having the time and resources to put such an extensive, theory into practice can seem little more than a pipe‐dream. It is argued that using a computer‐based application such as the Hypermedia Learning Tutorials (HLTs) as the heart of a REAL allows lecturers to take positive steps towards the creation of comprehensive, flexible, integrated learning environments. The concept of the HLT is discussed and a practical application in the field of advanced second‐language acquisition is described. Based on conceptual analysis and the results of preliminary student evaluation, it is argued that the HLT encompasses both in theory and in practice the chief qualities of REALs and can form the basis for their creation in a wide variety of disciplines

WILLINGNESS TO PARTICIPATE AND BIDS IN A FISHING VESSEL BUYOUT PROGRAM: A CASE STUDY OF NEW ENGLAND GROUNDFISH

An experimental fishing vessel buyout program was initiated in 1995 to remove vessels from the Northeast United States groundfish fishery. Information provided by the applicants to this program was used to evaluate the likely participation and potential cost of an expanded buyout initiative. This paper describes the pilot buyout program and the econometric procedures used to forecast participation and bids at various levels of program spending. Program participation and bid levels were modeled in two stages using participation and bid functions. The expanded buyout program, completed in April 1998, provided a unique opportunity to evaluate initial participation and cost forecasts. Methods used in this study are also applicable to modeling other fishery related economic decisions, such as the trading of individual transferable quota shares.Resource /Energy Economics and Policy,

A Multi-Layer, Multi-Robot Control Architecture for Long-Range, Dynamic Communication Links

A unified motion control architecture is presented for dynamic, long-range multi-robot communications networks, incorporating task abstraction that disassociates goals from implementation. In the task space, communication link states are specified, directly measured, and explicitly controlled yielding well-behaved task state trajectories. The control architecture uses task-level compensation to generate multi-robot formation mobility commands, and a cluster space controller transforms those formation commands to mobility commands for individual robots. The number of robots are selected to meet communications requirements and controlled through a multi-task coordination capability incorporated within the architecture. Robustness to performance commands, system configuration parameters, and external disturbances is demonstrated through a variety of simulations and experiments. These show how robots are dynamically positioned and switched into or out of operation in order to meet communications requirements

A Simple Matter of Herring Fishery Management

In 1996, the US New England Fishery Management Council formed a technical team (PDT) to develop a new plan for Atlantic Herring (Clupea harengus harengus). The inshore stock was close to fully exploited while the offshore stock was underexploited. There were few full-time herring harvesters and very few processors. Fresh bait was in demand by the adjacent lobster industry. The industry had experienced a collapse in the late seventies and the original plan was withdrawn by the government in 1982. By 1992 conditions were ripe for rational federal management which would guide the redevelopment of the fishery while preventing overharvest and the redevelopment of over-capacity. Despite the proposal of several ideas for permits (described) which would allow for what might now be described as a core fishery (Pontecorvo and Schrank, 2009), an open access regime was adopted in 2001. Several possible reasons for this are examined. Subsequently the PDT examined and proposed variations on what has come to be known as sectors in the Northeast (Kitts, this meeting). Their rejection in Amendment #1 (2006) is discussed. The explication of the sector notion in the amendment process helped spread the mis-labeled idea to other fisheries and other fishermen, however. Amendment #4 to the herring plan will revisit the sector options further. Other institutional complications to the application of secure privilegebased management in the US are discussed

Respiratory Sinus Arrhythmia as an Index of Vagal Activity during Stress in Infants: Respiratory Influences and Their Control

Respiratory sinus arrhythmia (RSA) is related to cardiac vagal outflow and the respiratory pattern. Prior infant studies have not systematically examined respiration rate and tidal volume influences on infant RSA or the extent to which infants' breathing is too fast to extract a valid RSA. We therefore monitored cardiac activity, respiration, and physical activity in 23 six-month old infants during a standardized laboratory stressor protocol. On average, 12.6% (range 0–58.2%) of analyzed breaths were too short for RSA extraction. Higher respiration rate was associated with lower RSA amplitude in most infants, and lower tidal volume was associated with lower RSA amplitude in some infants. RSA amplitude corrected for respiration rate and tidal volume influences showed theoretically expected strong reductions during stress, whereas performance of uncorrected RSA was less consistent. We conclude that stress-induced changes of peak-valley RSA and effects of variations in breathing patterns on RSA can be determined for a representative percentage of infant breaths. As expected, breathing substantially affects infant RSA and needs to be considered in studies of infant psychophysiology

Creating a Pilot Educational Psychiatry Website: Opportunities, Barriers, and Next Steps

Background: While medical students and residents may be utilizing websites as online learning resources, medical trainees and educators now have the opportunity to create such educational websites and digital tools on their own. However, the process and theory of building educational websites for medical education have not yet been fully explored. Objective: To understand the opportunities, barriers, and process of creating a novel medical educational website. Methods: We created a pilot psychiatric educational website to better understand the options, opportunities, challenges, and processes involved in the creation of a psychiatric educational website. We sought to integrate visual and interactive Web design elements to underscore the potential of such Web technology. Results: A pilot website (PsychOnCall) was created to demonstrate the potential of Web technology in medical and psychiatric education. Conclusions: Creating an educational website is now technically easier than ever before, and the primary challenge no longer is technology but rather the creation, validation, and maintenance of information for such websites as well as translating text-based didactics into visual and interactive tools. Medical educators can influence the design and implementation of online educational resources through creating their own websites and engaging medical students and residents in the process

A Novel Service-Oriented Professional Development Program for Research Assistants at an Academic Hospital: A Web-Based Survey

Background: Research assistants (RAs) are hired at academic centers to staff the research and quality improvement projects that advance evidence-based medical practice. Considered a transient population, these young professionals may view their positions as stepping-stones along their path to graduate programs in medicine or public health. Objective: To address the needs of these future health professionals, a novel program—Program for Research Assistant Development and Achievement (PRADA)—was developed to facilitate the development of desirable professional skill sets (ie, leadership, teamwork, communication) through participation in peer-driven service and advocacy initiatives directed toward the hospital and surrounding communities. The authors hope that by reporting on the low-cost benefits of the program that other institutions might consider the utility of implementing such a program and recognize the importance of acknowledging the professional needs of the next generation of health care professionals. Methods: In 2011, an anonymous, Web-based satisfaction survey was distributed to the program membership through a pre-established email distribution list. The survey was used to evaluate demographics, level of participation and satisfaction with the various programming, career trajectory, and whether the program's goals were being met. Results: Upon the completion of the survey cycle, a 69.8% (125/179) response rate was achieved with the majority of respondents (94/119, 79.0%) reporting their 3-year goal to be in medical school (52/119, 43.7%) or nonmedical graduate school (42/119, 35.3%). Additionally, most respondents agreed or strongly agreed that PRADA had made them feel more a part of a research community (88/117, 75.2%), enhanced their job satisfaction (66/118, 55.9%), and provided career guidance (63/117, 53.8%). Overall, 85.6% of respondents (101/118) agreed or strongly agreed with recommending PRADA to other research assistants. Conclusions: High response rate and favorable outlook among respondents indicate that the program had been well received by the program's target population. The high percentage of respondents seeking short-term entry into graduate programs in health care-related fields supports the claim that many RAs may see their positions as stepping-stones and therefore could benefit from a professional development program such as the one described herein. Strong institutional support and sustainable growth and participation are other indications of early success. Further evaluation is necessary to assess the full impact of the program, particularly in areas such as job satisfaction, recruitment, retention, productivity, and career trajectory, but also in reproducibility in other institutions

Ginseng on Hyperglycemia: Effects and Mechanisms

It has been reported that American ginseng attenuates hyperglycemia and may present itself as a supplement to diabetes therapy. However, the lack of standardization in the usage of ginseng root leads to inconclusive results when applied to diabetes treatment. The mechanisms of American ginseng root in the treatment of diabetes remains a mystery. This greatly limits the effective utilization of American ginseng in facilitating diabetic therapy. Initiating studies have shown that American ginseng increases insulin production and reduces cell death in pancreatic β-cells. Also, studies have revealed American ginseng's ability to decrease blood glucose in type II diabetes patients as well as in streptozotocin-induced diabetic animals (STZ-diabetic mice). These data suggest that effects of ginseng in improving hyperglycemia may alter mitochondrial function as well as apoptosis cascades to ensure cell viability in pancreatic islet cells. This review briefly summarizes current knowledge of ginseng components and clinical studies related to diabetes. Further research will be needed to explore and identify the component(s) of ginseng, which may be responsible for the beneficial effects observed in animal studies which could then be extrapolated to human islets
