Differential Effects of Internal and External Constraints on Sustainability Intentions: A Hierarchical Regression Analysis of Running Event Participants by Market Segment

There are immediate calls to action across all business sectors to address the adverse effects of climate change. The sport industry is not immune to these calls—practitioners have engaged participants to further the environmental initiatives of their events through creative messaging campaigns with mixed success. We examine the differential effects of internal and external constraints on sustainability intentions by market segment of a running event’s participants. This furthers our understanding of how to engage sport participants in sustainable behaviors at a sport event and improves the sustainable behavior outcomes of messaging campaigns. Our results support the principles of constraint theory and that internal constraints need to be addressed before external constraints are relevant. Internal constraints, such as lack of knowledge and lack of worth, predict variance in intentions to act sustainably (i.e., to dispose of waste correctly). After controlling for internal constraints, the external constraints of lack of interest by others to act sustainably, and lack of access and time, explain additional variance in sustainability intentions. We also found that each market segment varies on the impact of constraints that inhibit sustainability intentions, with the amount of variance in sustainability intention explained by such constraints varying from as low as 11.4% in one segment to as high as 33.1% in another. We then provide specific recommendations for future research and discuss how practitioners can use these results to ameliorate these constraints and increase sustainability intentions

Formation and Function of a Collegiate Athletics Sustainability Committee

Institutions of higher learning may be considered dual-identity organizations because of the perceived distinctiveness between universities’ academic and athletic missions. One way in which these barriers can be weakened is through cross-sector social partnerships (CSSPs), a form of collaborative engagement aimed at achieving a common societal goal. In this study, we examine the formation of a university-directed CSSP focused on enhancing environmentally sustainable initiatives within the Athletic Department. Interviews with 11 members of a so-called Green Team illustrate the processes of boundary spanning and boundary blurring. As demonstrated in the article, boundary spanning occurred under the leadership of a “champion” that assembled a team of stakeholders to assist with the major renovation of a pro-environmental football stadium. Though the sustainability committee has a common goal, not all experiences of Green Team members have been the same. In light of these differences, we identify key barriers and prescribe solutions that can lead to the realization of a new organizational form

Pollution, health, and the moderating role of physical activity opportunities

Cunningham GB, Wicker P, McCullough BP. Pollution, health, and the moderating role of physical activity opportunities. International Journal of Environmental Research and Public Health. 2020;17(17): 6272.Air and water pollution have detrimental effects on health, while physical activity opportunities have a positive relationship. The purpose of this study was to explore whether physical activity opportunities moderate the relationships among air and water pollution, and measures of health. Aggregate data were collected at the county level in the United States (n = 3104). Variables included the mean daily density of fine particle matter (air pollution), reported cases of health-related drinking water violations (water pollution), subjective ratings of poor or fair health (overall health), the number of physically and mentally unhealthy (physical and mental health, respectively), and the percentage of people living in close proximity to a park or recreation facility (access to physical activity). Air and water pollution have a significant positive effect on all measures of residents' poor health, while physical activity opportunities only have a negative effect on overall health and physical health. Access to physical activity only moderates the relationship between air pollution and all health outcomes. Since physical activity behavior can be more rapidly changed than some causes of pollution, providing the resident population with better access to physical activity can represent an effective tool in environmental health policy

Sport events and emissions reporting: an analysis of the Council for Responsible Sport standard in running events

The use of fossil fuels has pushed the world towards crucial ecological tipping points and a climate crisis. The rapid decarbonization of all sectors is necessary to limit the worst impacts of this. Within the sports and sport-tourism sectors, event organizers and policymakers are increasingly interested in assessing the environmental impacts of events and identifying the types of strategies needed to reduce their carbon footprint. This paper responds to calls for studies to examine and compare the environmental impacts of multiple sport events and contribute towards providing an enhanced understanding of key factors influencing the scale of those impacts. It focuses on assessing the carbon footprints of 28 mass participation running events in North America. The paper uses a methodology developed by the Council for Responsible Sport as part of its Responsible Sport Standard for Events accreditation process. The results highlight that variations existed between the events in terms of their reporting of GHG emissions. The average event generated 3363 MtCO2e (0.23 MtCO2e per capita), with Scope 3 emissions accounting for 99.9% of the total emissions, and 98.9% being attributable to participant travel. This demonstrates how the Council’s methodology can assist event organizers by providing valuable insights into the carbon footprint of their events and its potential value as an environmental management tool. The paper also discusses some of the challenges faced by event organizers in measuring the carbon footprint of their event, suggests strategies for reducing event emissions, and provides recommendations for strengthening the Council’s methodology and its contribution to global sustainability efforts

Fan Responses of Sponsored Environmental Sustainability Initiatives

The sport sector is advancing its efforts to be environmentally friendly. These efforts now include corporate sponsored environmental initiatives, yet fans’ responsiveness to such efforts remains unexamined. Specifically, in this study, the corporate-sponsored environmental initiatives of a college athletic department with an established history of environmental commitments were examined to evaluate the influence of a point of attachment, sport brand-sustainability fit, and receptivity to messaging on the sport organization’s desired outcomes of the campaign (i.e., sustainability behavioral, support for environmental initiative corporate partner). Data were collected from college football fans of an institution in the United States Midwest region using an internet-based survey after the 2019 football season (N = 548). We found that most of our hypotheses were supported. Specifically, attachment to athletics, athletics/sustainability fit, and ascription of responsibility to athletics explained 52.7% of the variance of receptivity to messaging from athletics. In turn, receptivity to sustainable messaging and behaviors explained 45.0% of the support for corporate partners. Our results show that sport practitioners should evaluate the ascription of responsibility their fans place on the sport organization to be environmentally responsible, increasing the receptivity of environmental messages and desired outcomes from such efforts. In addition, this study shows the versatility and applicability of the model to actual sponsored environmental sustainability campaigns of a sport organization

Economic Impacts of Non-Native Forest Insects in the Continental United States

Reliable estimates of the impacts and costs of biological invasions are critical to developing credible management, trade and regulatory policies. Worldwide, forests and urban trees provide important ecosystem services as well as economic and social benefits, but are threatened by non-native insects. More than 450 non-native forest insects are established in the United States but estimates of broad-scale economic impacts associated with these species are largely unavailable. We developed a novel modeling approach that maximizes the use of available data, accounts for multiple sources of uncertainty, and provides cost estimates for three major feeding guilds of non-native forest insects. For each guild, we calculated the economic damages for five cost categories and we estimated the probability of future introductions of damaging pests. We found that costs are largely borne by homeowners and municipal governments. Wood- and phloem-boring insects are anticipated to cause the largest economic impacts by annually inducing nearly $1.7 billion in local government expenditures and approximately$830 million in lost residential property values. Given observations of new species, there is a 32% chance that another highly destructive borer species will invade the U.S. in the next 10 years. Our damage estimates provide a crucial but previously missing component of cost-benefit analyses to evaluate policies and management options intended to reduce species introductions. The modeling approach we developed is highly flexible and could be similarly employed to estimate damages in other countries or natural resource sectors

Nonnative forest insects and pathogens in the United States: Impacts and policy options

We review and synthesize information on invasions of nonnative forest insects and diseases in the United States, including their ecological and economic impacts, pathways of arrival, distribution within the United States, and policy options for reducing future invasions. Nonnative insects have accumulated in United States forests at a rate of ~2.5 per yr over the last 150 yr. Currently the two major pathways of introduction are importation of live plants and wood packing material such as pallets and crates. Introduced insects and diseases occur in forests and cities throughout the United States, and the problem is particularly severe in the Northeast and Upper Midwest. Nonnative forest pests are the only disturbance agent that has effectively eliminated entire tree species or genera from United States forests within decades. The resulting shift in forest structure and species composition alters ecosystem functions such as productivity, nutrient cycling, and wildlife habitat. In urban and suburban areas, loss of trees from streets, yards, and parks affects aesthetics, property values, shading, stormwater runoff, and human health. The economic damage from nonnative pests is not yet fully known, but is likely in the billions of dollars per year, with the majority of this economic burden borne by municipalities and residential property owners. Current policies for preventing introductions are having positive effects but are insufficient to reduce the influx of pests in the face of burgeoning global trade. Options are available to strengthen the defenses against pest arrival and establishment, including measures taken in the exporting country prior to shipment, measures to ensure clean shipments of plants and wood products, inspections at ports of entry, and post-entry measures such as quarantines, surveillance, and eradication programs. Improved data collection procedures for inspections, greater data accessibility, and better reporting would support better evaluation of policy effectiveness. Lack of additional action places the nation, local municipalities, and property owners at high risk of further damaging and costly invasions. Adopting stronger policies to reduce establishments of new forest insects and diseases would shift the major costs of control to the source and alleviate the economic burden now borne by homeowners and municipalities.Organismic and Evolutionary Biolog

Amyloid-related imaging abnormalities in the DIAN-TU-001 trial of gantenerumab and solanezumab: lessons from a trial in dominantly inherited Alzheimer disease

OBJECTIVE: To determine the characteristics of participants with amyloid-related imaging abnormalities (ARIA) in a trial of gantenerumab or solanezumab in dominantly inherited Alzheimer disease (DIAD). METHODS: 142 DIAD mutation carriers received either gantenerumab SC (n=52), solanezumab IV (n=50), or placebo (n=40). Participants underwent assessments with the Clinical Dementia Rating® (CDR®), neuropsychological testing, CSF biomarkers, β-amyloid positron emission tomography (PET), and magnetic resonance imaging (MRI) to monitor ARIA. Cross-sectional and longitudinal analyses evaluated potential ARIA-related risk factors. RESULTS: Eleven participants developed ARIA-E, including 3 with mild symptoms. No ARIA-E was reported under solanezumab while gantenerumab was associated with ARIA-E compared to placebo (OR=9.1, CI[1.2, 412.3]; p=0.021). Under gantenerumab, APOE-ɛ4 carriers were more likely to develop ARIA-E (OR=5.0, CI[1.0, 30.4]; p=0.055), as were individuals with microhemorrhage at baseline (OR=13.7, CI[1.2, 163.2]; p=0.039). No ARIA-E was observed at the initial 225mg/month gantenerumab dose, and most cases were observed at doses >675mg. At first ARIA-E occurrence, all ARIA-E participants were amyloid-PET+, 60% were CDR>0, 60% were past their estimated year to symptom onset, and 60% had also incident ARIA-H. Most ARIA-E radiologically resolved after dose adjustment and developing ARIA-E did not significantly increase odds of trial discontinuation. ARIA-E was more frequently observed in the occipital lobe (90%). ARIA-E severity was associated with age at time of ARIA-E. INTERPRETATION: In DIAD, solanezumab was not associated with ARIA. Gantenerumab dose over 225mg increased ARIA-E risk, with additional risk for individuals APOE-ɛ4(+) or with microhemorrhage. ARIA-E was reversible on MRI in most cases, generally asymptomatic, without additional risk for trial discontinuation. This article is protected by copyright. All rights reserved
