Effects of childhood setting and interaction with nature on academic performance in introductory college-level courses in the environmental sciences

This study explored the relationships between student background and academic performance in college introductory environmental science (ES) courses at a large U.S. research university with the premise that this analysis may inform teaching practices, curricula, and efforts to increase retention. We surveyed over 700 students across eleven introductory ES courses and used multiple linear mixed-effects regressions to model the data. We found that students who grew up in rural settings or who had frequent childhood interactions with natural environments earned higher grades, on average, than students from urban settings or with fewer childhood interactions with natural environments. Our results indicate that students reporting frequent childhood interactions with forests, for example, were projected to earn grades up to 1.5 letter grades higher in these courses than students with no such interactions. In addition, students with frequent childhood interactions with nature were likelier to report that such interactions helped them in their ES course, suggesting that these students may recognize the value of these experiences. Greater interest in the subject matter also correlated with higher ES course grades, whereas amount of prior ES coursework did not. We discuss the possible implications of these correlations for ES academic performance and educational practice.     

Accelerated Decisionmaking via Action Learning at the Federal Deposit Insurance Corporation (FDIC)

Training courses are insufficient to solve the “wicked problems” facing organizations. Lengthy task forces also fail to meet urgent challenges that demand a rapid response. Intrigued by the success of General Electric's innovative WorkOuts, the Federal Deposit Insurance Corporation (FDIC) has adapted this tool into an accelerated decisionmaking process to enhance both managerial and organizational effectiveness. Executives participate in a compressed version of the FDIC's accelerated decisionmaking process during management training, developing solutions for real organizational challenges posed by a corporate officer. Once exposed to this nontraditional problem-solving method, the executives are encouraged to apply the method to problems in their own realms. Emerging business demands compelled an evolution in the methodology, including the addition of tools for conscious reflection on the process, what the participants learn from the experience, and how they can apply that wisdom to their management practices.     

The belief revision model: asymmetrical effects of noncontingency on human covariation learning

A noncontingent experience affects the subsequent detection of positive and negative contingencies between the same events. Experiments 1 and 2 showed that such preexposure can produce both an impairment in the detection of subsequent positive contingency and a facilitation of a negative one, independent of the level of contingency during the contingent phase. Experiment 3 raised difficulties for a model that assumes that associations to the context can explain this asymmetrical effect. Experiment 4 suggested that the different weights usually assigned to the different types of trials when computing the contingency between events can change as a result of a noncontingent experience with the same events. This change supports an account of the asymmetrical effect by a belief revision model based on a mechanism that updates the weights of the different trial types as a function of previous experience. More generally, the belief revision model is a statistical (i.e., nonassociative) model of learning that is capable of accounting for trial-order effects, which have long posed problems for statistical models.     

Partnership working in the production of clinical guidelines

This article describes a working partnership between the Cairns Clinical Librarian Service, Health Care Libraries, University of Oxford and the Emergency Department (ED) at the John Radcliffe Hospital, Oxford. This collaboration resulted in the establishment of a guideline development group in June 2002. The aim of the group is to produce a set of easily accessible, user-orientated, evidence-based guidelines for the use of clinicians in the Emergency Department, within a realistic timescale. The Cairns Clinical Librarian Project was built on previous models of clinical librarianship and incorporated an evaluation of previous programmes. The objective was to provide information to clinicians at the time and point of need. Consultation with the ED from the outset determined the approach adopted by the Cairns team. Clinical guidelines have been shown to improve clinical practice. Pending the introduction of nationally available protocols, we have begun to establish a collection of evidence-based guidelines using web-based architecture in conjunction with the Oxford Radcliffe Hospitals NHS Trust's IT department. A piece of diagnostic analysis was undertaken to ensure a coherent strategy was developed for the guideline project. An 'intermediate approach' was adopted, where existing valid guidelines were modified to fit local circumstances. We strove to be transparent at all times about all aspects of the guideline development process. Formative evaluation has shown how the application of evidence-based health care needs adequate resources and requires people with appropriate knowledge and skills. This article charts the progress of the project and highlights how the partnership between the clinical team and the Clinical Librarian has been deemed to be essential to the success of the project.     

Assessing Training Needs of HIV Program Providers

This article describes a mixed‐methods needs assessment, or developmental evaluation, that was conducted for the providers and stakeholders of Oklahoma's community‐based organizations (CBOs). The needs assessment, which was the first phase in developing training on outcome monitoring for their HIV prevention programs, relied on three evaluation approaches: Behavioral‐objectives, participatory, and empowerment. This article describes the background for the needs assessment, the needs assessment process, and the lessons learned. When dealing with such a complex issue as HIV prevention where multiple goals must be achieved for success, a mixed‐methods approach to needs assessment may better capture real‐world needs. Furthermore, it may increase acceptance of the needs assessment findings and conclusions by the diverse groups that have a stake in the evaluation. However, as this study exemplified, implementing and reporting a mixed‐methods needs assessment that is based on differing evaluation approaches is complex, challenging, and resource intensive. This study can contribute to theory building for mixed‐methods evaluation.     

Shaping a gender equality policy in higher education: which human capabilities matter?

South African institutions still confront gendered inequalities, irrespective of transformative national policies, compounded by the absence of a national gender equality policy for higher education. We therefore explore the potential of the capabilities approach (CA) to inform policy formation and argue for the development of a policy for higher education institutions based on opportunities for valuable functionings as the informational basis for gender equality. Using one university as our case study, data from 38 interviews with female and male students were analysed as part of a longitudinal study on Gender, Empowerment, Agency and Higher Education. The data reveal which opportunities these women and men find important for their personal development and directly and indirectly for gender equality. We conclude by discussing the implications of the data for stimulating public dialogues towards formulating a capabilities-based gender equality policy, as well as reflecting on the broader contributions the CA brings to policy development.     

High efficiency vortex trapping of circulating tumor cells

Circulating tumor cells (CTCs) are important biomarkers for monitoring tumor dynamics and efficacy of cancer therapy. Several technologies have been demonstrated to isolate CTCs with high efficiency but achieve a low purity from a large background of blood cells. We have previously shown the ability to enrich CTCs with high purity from large volumes of blood through selective capture in microvortices using the Vortex Chip. The device consists of a narrow channel followed by a series of expansion regions called reservoirs. Fast flow in the narrow entry channel gives rise to inertial forces, which direct larger cells into trapping vortices in the reservoirs where they remain circulating in orbits. By studying the entry and stability of particles following entry into reservoirs, we discover that channel cross sectional area plays an important role in controlling the size of trapped particles, not just the orbital trajectories. Using these design modifications, we demonstrate a new device that is able to capture a wider size range of CTCs from clinical samples, uncovering further heterogeneity. This simple biophysical method opens doors for a range of downstream interventions, including genetic analysis, cell culture, and ultimately personalized cancer therapy.
