Nature-Based Tourism Businesses in Colorado: Interpreting Environmental Ethics and Responsible Behavior

Tourism businesses operate from a primarily economic-centric point of view, but nature-based tourism businesses are also acutely aware of the need to sustain the natural resource that attracts the client to their outdoor recreation service. A preliminary qualitative inquiry reveals how nature-based tourism organizations in Colorado view themselves as operating from environmentally ethical positions, what specific actions they take to minimize negative environmental impacts, and how they educate their clients about resource conservation. Findings indicate that too often companies fail to realize opportunities in which they can encourage meaningful bonds between people and nature through the use of education and environmental interpretation. Education is seen more as a means to equip tourists with skills pertaining to a certain sport/activity, rather than as a way to enrich the total experience. Due to the industry’s reliance upon natural resources, a higher level of resource interpretation should be encouraged, promoting natural resource conservation

Hypersonic research engine project. Phase 2: Aerothermodynamic Integration Model (AIM) data reduction computer program, data item no. 54.16

The data reduction program used to analyze the performance of the Aerothermodynamic Integration Model is described. Routines to acquire, calibrate, and interpolate the test data, to calculate the axial components of the pressure area integrals and the skin function coefficients, and to report the raw data in engineering units are included along with routines to calculate flow conditions in the wind tunnel, inlet, combustor, and nozzle, and the overall engine performance. Various subroutines were modified and used to obtain species concentrations and transport properties in chemical equilibrium at each of the internal and external engine stations. It is recommended that future test plans include the configuration, calibration, and channel assignment data on a magnetic tape generated at the test site immediately before or after a test, and that the data reduction program be designed to operate in a batch environment

The (In)Determinacy of the Pictorial Sign: Evaluating Health Education Illustrations from a Semiotic Perspective

[Abstract] The basic point of departure for the present study was one of Habermas' principles of communicative ethics, namely universalization, requiring the acceptance (Zustimmung) of the communicative norms at play by all concerned without coercion. The study focused on evaluating the communicative acceptability of health education illustrations meant for an elderly (mean age 71.7 years), pre-dominantly Sesothospeaking (84.7%) and primarily female (87.1%) target group in Sharpeville, South Africa. The emphasis was on the relationship between the semiotic other (members of the target group) and the semiotic self (the researcher), i.e. on the contractual axis of semiosis in Johansen's 'semiotic pyramid' model. The first phase comprised a survey with questionnaires (n=140) to obtain input about pictorial illustration preferences. The respondents indicated their preferred option among a range of different pictorial signs and illustration approaches, explaining their choice. On the strength of this input, an illustrated nutrition education calendar was produced and disseminated in the target group. The second phase involved follow-up questionnaires (n=137) approximately one year later. The second set of questionnaires measured whether the target group wanted to move away from the previously agreed on pictorial signs and consensus-based pictorial illustration approach. The outcome was that the target group strongly disagreed with the introduction of new pictorial signs and illustration approaches. This result highlights that evaluating the acceptability of pictorial signs and illustration approaches in a particular target group is not necessarily primarily a question of understanding the complex and tenuous relationship between the referent and the iconic sign, but also about how pictorial meaning may be stabilized, or de-stabilized, as a result of a shifting and evolving relationship between the semiotic other and the semiotic self

Hypersonic research engine project. Phase 2: Some combustor test results of NASA aerothermodynamic integration model

Combustor test results of the NASA Aerothermodynamic Integration Model are presented of a ramjet engine developed for operation between Mach 3 and 8. Ground-based and flight experiments which provide the data required to advance the technology of hypersonic air-breathing propulsion systems as well as to evaluate facility and testing techniques are described. The engine was tested with synthetic air at Mach 5, 6, and 7. The hydrogen fuel was heated to 1500 R prior to injection to simulate a regeneratively cooled system. Combustor efficiencies up to 95 percent at Mach 6 were achieved. Combustor process in terms of effectiveness, pressure integral factor, total pressure recovery and Crocco's pressure-area relationship are presented and discussed. Interactions between inlet-combustor, combustor stages, combustor-nozzle, and the effects of altitude, combustor step, and struts are observed and analyzed

Open Educational Resources @ Butler University: Gateway to Access and Advocacy in Open Education

This session reports on the progress of the Open Education Resources @ Butler University web portal. The portal was designed with 2 goals: (1) to provide a platform for the advocacy of OERs and (2) to provide an extensive list of resources with consideration given to their integration among departmental introductory courses at Butler. This project explicates a role academic libraries can play in Open Education

Measuring Altruistic Impact: A Model for Understanding the Social Justice of Open Access

INTRODUCTION Traditional assessment of ways in which open access initiatives and institutional repositories have provided a return on investment normally use pragmatic measures such as download counts and citation benefits. This pragmatic approach misses out on the powerful altruistic impact of improving access to international and/or marginalized communities. Using a frame of social justice, this article considers the importance of developing altruistic measures of repositories, particularly for institutions with missions specifically related to social justice and related themes. METHODS Using web analytics data for search keywords from eight institutions and geographic usage data from nine institutions, the authors were able to determine how well social justice related content is accessed by search engines and how much overall content is accessed internationally, particularly by lower-resourced countries. A social justice term list was developed to permit corpus overlap analysis with each institution’s search keywords, while the World Bank country income lists were used to determine international access by low and low-middle income countries. RESULTS Universities with mission statements explicitly mentioning social justice or Catholic social teaching had greater overlap with the social justice corpus. Low and low-middle income countries as defined by the World Bank were among the most engaged users. All institutions had at least one social justice search term in their top ten; Marquette University had five. Collection development in social science and environmental sustainability at Loyola University Chicago successfully increased this term overlap year-over-year and increased user engagement as measured by session length. DISCUSSION The results of this exploratory study indicate that it is possible to use repository data to evaluate the success of an institution’s open access and social justice initiatives. The year-over-year improvement of Loyola’s numbers suggest in addition that it is possible to increase social justice impact through collection development. Performing an analysis of social justice impact can be used as an overall strategy for repository success and outreach on campus, particularly for institutions where social justice is an important part of the campus identity. For repositories in need of further resources, the ability to quantify impact for university administrators and decision-makers may be of use. CONCLUSION For institutions with a social justice mission, improving social justice content may improve repository ranking in social justice related search results. Collection development strategies should focus on departments and/or individuals who are working in social justice related areas, which defined broadly could encompass much of an institution. For institutions that emphasize social justice, it may be easier to approach faculty who might not otherwise have an interest in open access issues
