Outdoor Recreation Constraints: An Examination of Race, Gender, and Rural Dwelling

We assess whether traditionally marginalized groups in American society (African-Americans, women, rural dwellers) perceive more constraints to outdoor recreation participation than other groups. A series of logistic regressions are applied to a national recreation survey and used to model the probability that individuals perceive certain constraints to participating in outdoor recreation activities. Twelve constraints related to health, facilities, socioeconomic standing, and other personal factors are examined for both participants and nonparticipants of outdoor recreation. We model the probability that individuals report being constrained in participating in their favorite activities as a function of race, gender, and rural residence. In addition, we control for income, age, regional differences, and activity groupings. Of the three groups examined, women are most likely to feel constrained--for instance, by personal safety concerns, inadequate facilities and information, insufficient funds, and outdoor pests. Race is not a significant predictor of constraints for participants, but nonparticipating African-Americans are more likely than whites to feel personal safety concerns inhibit their outdoor recreation opportunities. Rural residence does not appear to be an important factor among either participants or nonparticipants in explaining the probability that an individual feels constrained in outdoor recreation participation

Visitor Support for Recreation Fees in Georgia State Parks

Abstract Public land managers are experiencing increasing pressure to create parks that are self-sustaining. Recreation fees can help managers achieve this goal, but tradeoffs associated with fees often produce undesired consequences (i.e., declining visitation) that warrant further investigation. This study used intercept surveys (n = 1049) to examine support for recreation fees among visitors to Georgia state parks. Participants were evenly split regarding their willingness to pay to enter state parks, with a mean willing to pay increase about $2 above the current$5 parking fee. Proposed fee increases negatively affected projected visitation among all groups, particularly low-income visitors. Place attachment ratings were the strongest predictor of support for fees. Results suggest that, to accommodate a diverse clientele, managers could work on strengthening visitors’ attachment to and reliance upon state parks while developing flexible pricing schemes that appeal to a range of potential users

PdZn catalysts for CO2 hydrogenation to methanol using chemical vapour impregnation (CVI)

The formation of PdZn bimetallic alloys on ZnO, TiO2 and Al2O3 supports was investigated, together with the effect of alloy formation on the CO2 hydrogenation reaction. The chemical vapour impregnation (CVI) method produced PdZn nanoparticles with diameters of 3–6 nm. X-ray photoelectron spectroscopy and X-ray diffraction revealed the changes in the structure of the PdZn alloy that help stabilise formate intermediates during methanol synthesis. PdZn supported on TiO2 exhibits high methanol productivity of 1730 mmol kgcat−1 h−1 that is associated with the high dispersion of the supported PdZn alloy

Scraping the Social? Issues in live social research

What makes scraping methodologically interesting for social and cultural research? This paper seeks to contribute to debates about digital social research by exploring how a ‘medium-specific’ technique for online data capture may be rendered analytically productive for social research. As a device that is currently being imported into social research, scraping has the capacity to re-structure social research, and this in at least two ways. Firstly, as a technique that is not native to social research, scraping risks to introduce ‘alien’ methodological assumptions into social research (such as an pre-occupation with freshness). Secondly, to scrape is to risk importing into our inquiry categories that are prevalent in the social practices enabled by the media: scraping makes available already formatted data for social research. Scraped data, and online social data more generally, tend to come with ‘external’ analytics already built-in. This circumstance is often approached as a ‘problem’ with online data capture, but we propose it may be turned into virtue, insofar as data formats that have currency in the areas under scrutiny may serve as a source of social data themselves. Scraping, we propose, makes it possible to render traffic between the object and process of social research analytically productive. It enables a form of ‘real-time’ social research, in which the formats and life cycles of online data may lend structure to the analytic objects and findings of social research. By way of a conclusion, we demonstrate this point in an exercise of online issue profiling, and more particularly, by relying on Twitter to profile the issue of ‘austerity’. Here we distinguish between two forms of real-time research, those dedicated to monitoring live content (which terms are current?) and those concerned with analysing the liveliness of issues (which topics are happening?)

Challenging Social Cognition Models of Adherence:Cycles of Discourse, Historical Bodies, and Interactional Order

Attempts to model individual beliefs as a means of predicting how people follow clinical advice have dominated adherence research, but with limited success. In this article, we challenge assumptions underlying this individualistic philosophy and propose an alternative formulation of context and its relationship with individual actions related to illness. Borrowing from Scollon and Scollon’s three elements of social action – “historical body,” “interaction order,” and “discourses in place” – we construct an alternative set of research methods and demonstrate their application with an example of a person talking about asthma management. We argue that talk- or illness-related behavior, both viewed as forms of social action, manifest themselves as an intersection of cycles of discourse, shifting as individuals move through these cycles across time and space. We finish by discussing how these dynamics of social action can be studied and how clinicians might use this understanding when negotiating treatment with patients

What’s Sex (Composition) Got to Do with It? The Importance of Sex Composition of Gangs for Female and Male Members’ Offending and Victimization

Sex composition of groups has been theorized in organizational sociology and found in prior work to structure female and male members’ behaviors and experiences. Peer group and gang literature similarly finds that the sex gap in offending varies across groups of differing sex ratios. Drawing on this and other research linking gang membership, offending, and victimization, we examine whether sex composition of gangs is linked to sex differences in offending in this sample, further assess whether sex composition similarly structures females’ and males’ victimization experiences, and if so, why. Self-report data from gang members in a multi-site, longitudinal study of 3,820 youths are employed. Results support previous findings about variations in member delinquency by both sex and sex composition of the gang and also indicate parallel variations in members’ victimization. These results are further considered within the context of facilitating effects such as gender dynamics, gang characteristics, and normative orientation
