Ethical Frameworks, Moral Practices and Outdoor Education

Discoveries and insights from quantum physics and chaos theory help create new metaphors about. ethical frameworks and moral practices in outdoor education. Using concepts such as fractals, fields, and strange attractors, we explore new ways to view research results, scholarly writings, and creative endeavors related to outdoor education. In addition, we evaluate four themes related to the present ethical discourse in outdoor education and sketch new directions for moral practice

Outdoor Leadership: A Question of Vision and Ethics

Outdoor education increasingly includes programs for youth-at-risk, multi-cultural groups, battered women, and other special populations. The diversity of such groups and their needs and expectations place additional demands upon the outdoor leader. Good judgement on a trip with seniors may not be identical to good judgement on a trip with youth-at-risk; group exercises appropriate for young males of color may be inappropriate for women who have been abused. The diverse populations and situations will require outdoor leaders to become more self-aware, reflective, and sensitive to culture, race, and gender differences (Greenleaf, 1970; Shapiro, 1988; Terry, 1988). Resolving conflicts and ethical differences will also include competencies in critical thinking and ethical decision-making as applied to outdoor recreation/education (Hunt, 1989; Warren, 1989). This exploratory study looked at student journal writings and papers during a course about ethical outdoor leadership that included readings from the areas of outdoor recreation and ethical leadership. The text of 26 students was analy:zed using the Minnesota Contextual Content Analysis computer program (McTavish & Pirro, 1989) and traditional content analysis. Preliminary results indicate a conceptual difference between writings about ethical leadership and outdoor leadership. The students perceived the material about outdoor leadership as practical and actionented. They saw the infonnation about leadership and ethics as being academic and not­very pragmatic. As the course progressed, and in their final papers, the material of both fields begins to be integrated using examples of class exercises and discussions. Students provided more ethical analysis when discussing iri:.Class exercises and student interaction than responding direttly to readings or lecture information. The use of critical thinking skills did not increase, which may reflect the lack of consistent, direct teaching of these skills. Fmally, the students made small changes in applying the principles to their own leadership and ethical frameworks. Future research should address preconceptions about leadership, direct .teaching of critical thinking skills and ability to describe ethical dilemmas, the role of ethical followership, and the integration of readings with class experiences for analysis and transfer of ethical leadership skills

Fluorescent visualization of a spreading surfactant

The spreading of surfactants on thin films is an industrially and medically important phenomenon, but the dynamics are highly nonlinear and visualization of the surfactant dynamics has been a long-standing experimental challenge. We perform the first quantitative, spatiotemporally-resolved measurements of the spreading of an insoluble surfactant on a thin fluid layer. During the spreading process, we directly observe both the radial height profile of the spreading droplet and the spatial distribution of the fluorescently-tagged surfactant. We find that the leading edge of spreading circular layer of surfactant forms a Marangoni ridge in the underlying fluid, with a trough trailing the ridge as expected. However, several novel features are observed using the fluorescence technique, including a peak in the surfactant concentration which trails the leading edge, and a flat, monolayer-scale spreading film which differs from concentration profiles predicted by current models. Both the Marangoni ridge and surfactant leading edge can be described to spread as $R \propto t^{\delta}$. We find spreading exponents, $\delta_H \approx 0.30$ and $\delta_\Gamma \approx 0.22$ for the ridge peak and surfactant leading edge, respectively, which are in good agreement with theoretical predictions of $\delta = 1/4$. In addition, we observe that the surfactant leading edge initially leads the peak of the Marangoni ridge, with the peak later catching up to the leading edge

Experimental Infection of Brazilian Free-Tailed Bats (\u3ci\u3eTadarida brasiliensis\u3c/i\u3e) with Two Strains of SARS-CoV-2

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is presumed to have originated from wildlife and shares homology with other bat coronaviruses. Determining the susceptibility of North American bat species to SARS-CoV-2 is of utmost importance for making decisions regarding wildlife management, public health, and conservation. In this study, Brazilian free-tailed bats (Tadarida brasiliensis) were experimentally infected with two strains of SARS-CoV-2 (parental WA01 and Delta variant), evaluated for clinical disease, sampled for viral shedding and antibody production, and analyzed for pathology. None of the bats (n = 18) developed clinical disease associated with infection, shed infectious virus, or developed histopathological lesions associated with SARS-CoV-2 infection. All bats had low levels of viral RNA in oral swabs, six bats had low levels of viral RNA present in the lungs during acute infection, and one of the four bats that were maintained until 28 days post-infection developed a neutralizing antibody response. These findings suggest that Brazilian free-tailed bats are permissive to infection by SARS-CoV-2, but they are unlikely to contribute to environmental maintenance or transmission

Moving forward in circles: challenges and opportunities in modelling population cycles

Population cycling is a widespread phenomenon, observed across a multitude of taxa in both laboratory and natural conditions. Historically, the theory associated with population cycles was tightly linked to pairwise consumer–resource interactions and studied via deterministic models, but current empirical and theoretical research reveals a much richer basis for ecological cycles. Stochasticity and seasonality can modulate or create cyclic behaviour in non-intuitive ways, the high-dimensionality in ecological systems can profoundly influence cycling, and so can demographic structure and eco-evolutionary dynamics. An inclusive theory for population cycles, ranging from ecosystem-level to demographic modelling, grounded in observational or experimental data, is therefore necessary to better understand observed cyclical patterns. In turn, by gaining better insight into the drivers of population cycles, we can begin to understand the causes of cycle gain and loss, how biodiversity interacts with population cycling, and how to effectively manage wildly fluctuating populations, all of which are growing domains of ecological research

Targeted Nasal Vaccination Provides Antibody-Independent Protection Against Staphylococcus aureus

Despite showing promise in preclinical models, anti-Staphylococcus aureus vaccines have failed in clinical trials. To date, approaches have focused on neutralizing/opsonizing antibodies; however, vaccines exclusively inducing cellular immunity have not been studied to formally test whether a cellular-only response can protect against infection. We demonstrate that nasal vaccination with targeted nanoparticles loaded with Staphylococcus aureus antigen protects against acute systemic S. aureus infection in the absence of any antigen-specific antibodies. These findings can help inform future developments in staphylococcal vaccine development and studies into the requirements for protective immunity against S. aureu
